Description

Storage type massage device capable of being led out

Technical Field

The present invention relates to a retractable massage device capable of being drawn out, and more particularly, to a retractable massage device capable of being drawn out from the inside of a main body portion or from the inside of the main body portion, in which a drawing-out portion provided with a massage module is housed.

Background

Massage (massage) is a method of adjusting a physical change of a massage subject by applying various mechanical stimuli such as kneading, pressing, stretching, beating, or moving the body to a body part of the massage subject, and contributing to blood circulation and relieving fatigue of the massage subject.

For economic and time reasons, there is an increasing demand for massage devices or massage apparatuses that provide artificial massage functions. That is, as the need to relieve stiff muscles and to relieve fatigue or stress by massage increases, various massage devices have been developed and proposed that are both time and cost effective.

Recently, the massage device may be manufactured as a bed, and a user may receive a massage in a lying state. Such a bed-type massage device provides massage by stimulating the waist and back of a user lying down as the massage module moves.

On the other hand, the conventional bed massage device has a disadvantage of being bulky because it must have a length at least equal to the height of the user. However, in order to solve such a problem, the conventional massage apparatus includes a structure in which a portion corresponding to the leg portion can be manually folded, but there is an inconvenience in that the leg portion needs to be manually operated every time a massage is provided. However, in order to solve such a problem, the conventional massage apparatus includes a structure in which a portion corresponding to the leg portion can be manually folded, but there is an inconvenience in that the leg portion needs to be manually operated every time a massage is provided.

In addition, there is a problem in that the space utilization is low because the bed massage device needs to be disposed in a space such as a living room or a bedroom other than a bed in which the user sleeps.

Accordingly, there is a need for a device for receiving a bed massage device in a extractable manner on an existing bed, so that a separate space for placing the bed massage device is not required.

The link mechanism 300 may be provided with a moving portion at one side thereof and a hinge portion at the other side thereof. The moving portion of the link mechanism 300 is formed at one end region of the link mechanism 300, and can be moved along any one of the main body portion 100 and the lead-out portion 200 by the driving force of the driving portion 500. The hinge portion of the link mechanism 300 is formed at the other end region of the link mechanism 300, and may be coupled with the remaining one hinge of the main body portion 100 and the lead-out portion 200.

For example, when the link mechanism 300 is formed of the first link member 310, the first link member 310 includes the first connection portion 311 connected to the first link mounting portion 111 of the main body portion 100, and includes the second connection portion 312 connected to the second link mounting portion 211 of the lead-out portion 200.

The first connection portion 311 forms a hinge portion hinge-coupled to the first link mounting portion 111, and the second connection portion 312 forms a moving portion movably mounted to the second link mounting portion 211.

For example, when the link mechanism 300 is formed of the second link member 320, the second link member 320 includes the third connecting portion 321 connected to the first link mounting portion 111 of the main body portion 100, and includes the fourth connecting portion 322 connected to the second link mounting portion 211 of the lead-out portion 200. The third connecting portion 321 forms a moving portion movably mounted to the first link mounting portion 111, and the fourth connecting portion 322 forms a hinge portion hinge-coupled to the second link mounting portion 211.

As described above, when the link mechanism 300 is formed of a single link member, that is, when the link mechanism 300 is formed of any one of the first link member 310 or the second link member 320, a moving portion formed at one end region of the link mechanism 300, which can move along any one of the first link mounting portion 111 of the main body portion 100 or the second link mounting portion 211 of the lead-out portion 200, is included, and a hinge portion formed at the other end region of the link mechanism 300, which is hinge-coupled to the remaining one of the first link mounting portion 111 of the main body portion 100 or the second link mounting portion 211 of the lead-out portion 200, is included.

When the link mechanism 300 formed of the first link member 310 or the second link member 320 rotates about the hinge portion as an axis and the moving portion moves the link mounting portion, the length of the link mechanism 300 in the width direction may be changed.

According to the stowable massage device 10 of an embodiment of the present invention, one side of the driving part 500 may be connected to one of the body part 100 and the lead-out part 200, to which the hinge part is incorporated, and the other side may be connected between one end and the other end of the link mechanism 300. The link mechanism 300 expands or contracts in the width direction, so that the distance of separation of the lead-out portion 200 with respect to the main body portion 100 can be adjusted.

In the stowable massaging device 10 of an embodiment of the invention, as shown in fig. 4, the link mechanism 300 may include both the first link member 310 and the second link member 320.

The first connection portion 311 of the first link member 310 of the link mechanism 300 forms a hinge portion hinge-coupled to the first link mounting portion 111, and the second connection portion 312 forms a moving portion movably mounted to the second link mounting portion 211. In addition, the third connecting portion 321 of the second link member 320 forms a moving portion movably mounted to the first link mounting portion 111, and the fourth connecting portion 322 forms a hinge portion hinge-coupled to the second link mounting portion 211.

As described above, even in the case where the link mechanism 300 includes the first link member 310 and the second link member 320, the link mechanism 300 includes, at one end region thereof, a moving portion that can move along any one of the first link mounting portion 111 of the main body portion 100 or the second link mounting portion 211 of the lead-out portion 200, and includes, at the other end region thereof, a hinge portion that is hinge-coupled to the remaining one of the first link mounting portion 111 of the main body portion 100 or the second link mounting portion 211 of the lead-out portion 200. The first link member 310 and the second link member 320 are connected to each other centering on the link shaft 351.

However, when the link mechanism 300 includes the first link member 310 and the second link member 320, one end regions of the first link member 310 and the second link member 320 may be coupled to the first link mounting portion 111 in a manner different from each other, and the other end regions of the first link member 310 and the second link member 320 may also be coupled to the second link mounting portion 211 in a manner different from each other.

For example, the first connection portion 311, which is any one of the first connection portion 311 and the third connection portion 321 belonging to one end region, forms a hinge portion, and the third connection portion 321, which is the other one, forms a moving portion, and the second connection portion 312, which is any one of the second connection portion 312 and the fourth connection portion 322 belonging to the other end region, forms a moving portion, and the fourth connection portion 322, which is the other one, forms a hinge portion. At this time, the plurality of hinge portions formed at one end portion and the other end portion of the link mechanism 300 may be disposed in correspondence with each other, and the plurality of moving portions formed at one end portion and the other end portion may be disposed in correspondence with each other.

Thus, the link mechanism 300 can stably perform the expansion motion or the contraction motion.

The link mechanism 300 provided with the first link member 310 and the second link member 320 can change the length of the link mechanism 300 in the width direction in the same manner as the link mechanism 300 formed of a single link member. That is, when the first link member 310 and the second link member 320 of the link mechanism 300 are rotated about the hinge portion as an axis and the moving portion moves the link mounting portion, the length of the link mechanism in the width direction can be changed.

Since the first link member 310 and the second link member 320 are operatively connected by the link shaft 351, by providing the driving force of the driving portion 500 to at least any one of the first link member 310 and the second link member 320, the link mechanism 300 is extended or contracted in the width direction, whereby the distance of separation of the lead-out portion 200 with respect to the main body portion 100 can be adjusted.

On the other hand, in the description with reference to the drawings, for convenience of description, one end region of the link mechanism 300 is described as a region connected to the main body portion 100, and the other end region of the link mechanism 300 is described as a region connected to the lead-out portion 200, but should not be construed restrictively. One end region of the link mechanism 300 may be a region connected to the lead-out portion 200, and the other end region of the link mechanism 300 may be a region connected to the main body portion 100. One end and the other end region of the linkage 300 should be understood from the context of the relevant description.

Fig. 5 is a plan view showing a state in which the storage type massage device according to an embodiment of the present invention is provided above the central axis of the drawing portion and is extended and contracted.

According to an embodiment of the present invention, the link mechanism 300 is configured to adjust the separation distance between the main body part 100 and the lead-out part 200 by pushing and pulling the region corresponding to the center of gravity of the lead-out part 200. The center of gravity of the lead-out portion 200 corresponds to the moving path of the massage module 400. By configuring components related to the massage module 400 and/or the action of the massage module 400, the lead 200 may have a biased weight distribution.

The lead-out portion 200 is formed to provide a massage in a state where the user lies down. As described above, the lead portion 200 may include the massage providing portion 240 composed of a separately formed bed type massage device, or may be formed in a form integrally with the massage providing portion 240. In both cases, the massage module 400 is provided so as to be movable along the opening 204a of the upper support surface 204 of the lead-out portion 200 that supports the body of the user.

The opening 204a formed in the support surface 204 of the lead portion 200 extends in the vertical longitudinal direction corresponding to the upper body portion of the user, for example, corresponding to the portions corresponding to the shoulder portion and the back portion. Further, a rack for guiding movement of the massage module 400 is provided adjacent to the opening 204a, and an assembly related to movement of the massage module 400 is provided. The massage module 400 serves as a component for providing a plurality of massage modes, which is a component having a relatively large weight.

Therefore, the lead portion 200 is not in a form in which the entire weight is uniformly distributed, but includes a moving path of the massage module 400, a relatively large weight is formed in a region where the massage module 400 is located, and a center of gravity of the lead portion 200 is formed in a region where the massage module 400 is located.

According to an embodiment of the present invention, since the region where the massage module 400 moves, i.e., the opening 204a, is formed corresponding to a portion of the lead-out portion 200, for example, corresponding to the upper body of the user, the center of gravity of the lead-out portion 200 may be formed in the region corresponding to the opening 204a, i.e., on the upper side of the lead-out portion 200.

Therefore, the center of gravity of the lead-out portion 200 may be located above the lead-out portion center axis l including a relatively large number of openings 204a, with reference to the lead-out portion center axis l dividing the length of the lead-out portion 200 into half. The massage module 400 may temporarily partially enter the lower portion of the lead-out portion central axis l according to the formed length of the opening portion 204 a.

However, the movement of the lead portion 200 is generally performed in a state where the massage module 400 is in an operation standby state on the upper side of the opening 204a, and the center of gravity of the lead portion 200 may be formed not only by the massage module 400 but also by a combination of the arrangement of components related to the movement of the massage module 400, for example, racks and the like, so that the center of gravity of the lead portion 200 is formed at a position biased to the upper side.

According to the embodiment of the present invention, the link mechanism 300 is disposed in such a manner that the movement area of the center of the link mechanism 300 is biased to the upper side of the extraction center axis l of the extraction portion 200. For example, the movement region of the center of the link mechanism 300 may be disposed above the lead portion center axis l of the lead portion 200.

When the link mechanism 300 is formed of a single link member, the center of the link mechanism 300 is formed between the hinge portion of one end region and the moving portion of the other end region. When the link mechanism 300 is formed of a plurality of link members, the center of the link mechanism 300 may be formed as the link shaft 351. Thus, the center of the linkage 300 includes the link shaft 351.

When the link mechanism 300 expands and contracts in the width direction, the center of the link mechanism 300 and the link shaft 351 have movement in the width direction and movement in the length direction. According to the embodiment of the present invention, the link mechanism 300 is connected between the main body portion 100 and the lead-out portion 200 such that the movement in the longitudinal direction of the link mechanism 300 is biased to the upper side of the lead-out portion center axis l of the lead-out portion 200, for example, the movement in the longitudinal direction is performed at the upper side of the lead-out portion center axis l of the lead-out portion 200. Thereby, the link mechanism 300 can adjust the separation distance between the main body portion 100 and the lead-out portion 200 by pushing and pulling the region corresponding to the center of gravity of the lead-out portion 200.

The link mechanism 300 of an embodiment of the present invention is connected to the first link mounting portion 111 and/or the second link mounting portion 211 such that a connection portion disposed on an upper side among connection portions formed in one end region and/or the other end region forms a hinge portion. In addition, a connection portion disposed on the lower side, among connection portions formed in one end region and/or the other end region of the link mechanism 300, is connected to the first link mounting portion 111 and/or the second link mounting portion 211, so that the moving portion forms a moving portion.

For example, the first connection portion 311 disposed at the upper side in one end region of the link mechanism 300 and the fourth connection portion 322 disposed at the upper side in the other end region will form a hinge portion, and the third connection portion 321 disposed at the lower side in one end region of the link mechanism 300 and the second connection portion 312 disposed at the lower side in the other end region will form a moving portion.

Since the center of the link mechanism 300 and the link shaft 351 are formed in the region corresponding to the center of gravity of the lead-out portion 200, when the link mechanism 300 is extended and contracted, the link mechanism 300 pushes or pulls (pulls) the region corresponding to the center of gravity of the lead-out portion 200.

As described more specifically with reference to fig. 5, the first connection portion 311 disposed on the upper side of the first link member 310 of the link mechanism 300 forms a hinge portion at the first link mounting portion 111 and is connected thereto, and the fourth connection portion 322 disposed on the upper side of the second link member 320 forms a hinge portion at the second link mounting portion 211 and is connected thereto. The second connection portion 312 disposed at the lower side in the first link member 310 forms a moving portion at the second link mounting portion 211 and is connected thereto, and the third connection portion 321 disposed at the lower side in the second link member 320 forms a moving portion at the first link mounting portion 111 and is connected thereto.

Therefore, the distance (i.e., height) of the link mechanism 300 from the lead-out portion central axis l to the link shaft 351 of the link mechanism 300 when extended is greater than the distance (i.e., height) of the link mechanism 300 from the lead-out portion central axis l to the link shaft 351 when contracted.

That is, when the link mechanism 300 is extended, the first link member 310 located at the lower portion of the lead-out portion central axis l, the second connecting portion 312 and the third connecting portion 321, which are moving portions of the lower side of the second link member 320, are moved to the upper sides of the first link mounting portion 111 and the second link mounting portion 211. Therefore, when the link mechanism 300 is extended, the position of the link shaft 351, which is the center of the link mechanism 30, will rise. Thereby, the movement stability of the lead portion 200 can be ensured.

Referring to fig. 5, in order to provide a driving force required for driving the link mechanism 300, an actuator 510 as a driving part 500 may be included. The driving section 500 is not limited to the actuator 510, and various driving sections may be provided. The driving unit 500 will be described in detail with reference to fig. 9 to 13.

According to an embodiment of the present invention, a guide rail may be included to guide the movement of the moving part of the link mechanism 300.

Fig. 6 is a view for explaining a first embodiment of a guide rail in a storage type massage apparatus according to an embodiment of the present invention.

Referring to fig. 6, a guide rail 610 for guiding movement of the moving part of the link mechanism 300 may be formed at least one of the first link mounting part 111 of the main body part 100 and the second link mounting part 211 of the lead part 200.

When the link mechanism 300 is formed of a single link member, for example, when the link mechanism 300 is formed of the first link member 310, the first link attachment portion 111 of the main body portion 100 is hinge-coupled with the first connection portion 311, and the second link attachment portion 211 of the lead portion 200 may be formed with a guide rail for guiding movement of the second connection portion 312 as a moving portion.

In addition, for example, when the link mechanism 300 is formed of the second link member 320, a guide rail for guiding the movement of the third connecting portion 321 as a moving portion may be formed at the first link mounting portion 111 of the main body portion 100, and the fourth connecting portion 322 may be hinge-coupled to the second link mounting portion 211 of the lead portion 200.

When the link mechanism 300 includes a plurality of link members, for example, when the link mechanism 300 includes the first link member 310 and the second link member 320, in order to guide the movement of each moving portion of the first link member 310 and the second link member 320, a guide rail 610 may be formed at each of the first link mounting portion 111 and the second link mounting portion 211. However, the guide rail 610 is only one embodiment of a guide means provided to the main body portion and/or the lead-out portion for guiding the movement of the moving portion, and the present invention is not limited to the guide rail.

As shown in fig. 6, the guide rail 610 extends a predetermined length in the length direction of the first link mounting portion 111 and the second link mounting portion 211. A moving member 301 that moves along the guide rail 610 is attached to the moving portion of the link mechanism 300, and as the moving member 301 moves along the guide rail 610, the movement of the moving portion of the link mechanism 300 can be guided. The moving member 301 may be formed of a roller (roller). However, the present invention is not limited thereto, and a bearing, a bush, or the like may be applied.

The guide rail 610 includes a disengagement preventing jaw 612 to prevent the moving member 301 from being disengaged. The escape prevention jaw 612 forms an upper surface of the guide rail 610, and is disposed on both sides with an upper surface opening portion through which the moving member 301 moves, so as to extend in the longitudinal direction. The upper opening portion between the escape prevention jaws 612 is formed smaller than the diameter of the moving member 301, so that the moving member 301 can be prevented from escaping to the upper portion of the guide rail 610.

The guide rail 610 includes an introduction portion for inserting the moving member 301 to the inside of the guide rail 610. The introduction portion is formed by a side opening portion 611 formed at a side of the guide rail 610. The side opening 611 is formed to be opened at one side and/or the other side in the length direction of the guide rail 610 so that the moving member 301 can be introduced. One side of the guide rail 610 may include a side opening portion 611, and the other side of the guide rail 610 may be closed to prevent the moving member 612 from being detached. After the introduction of the moving member 612, the side opening 611 may be shielded to prevent the moving member 612 from being detached.

The driving force required when the moving member 301 connected to the moving portion of the link mechanism 300 moves along the guide rail 610 may be provided by the actuator 510. One side of the actuator 510 may be connected to the first support member 110 of the body part 100, and the other side of the actuator 510 may be connected between one end and the other end of the link mechanism 300.

As shown in fig. 6, the other end of the actuator 510 may be connected to the link shaft 521, but is not limited thereto, and may be connected between one end and the other end of the link mechanism 300. One side of the actuator 510 is disposed in an unretained space in the internal space of the main body 100, and extends toward the link mechanism 300.

Fig. 7 is a view for explaining a second embodiment of a guide rail in the stowable massaging device of the invention.

The guide rail 610b according to the second embodiment shown in fig. 7 is different in structure of an introduction portion of the moving member 301 introduced into the inside of the guide rail 610, compared to the guide rail 610 according to the first embodiment shown in fig. 6. In describing the guide rail 610b according to the second embodiment, the same or similar parts as those of the guide rail 610 according to the first embodiment are omitted or briefly described.

As described with reference to fig. 6, the guide rail 600b is provided with a disengagement preventing jaw 612, and the disengagement preventing jaw 612 forms an upper surface of the guide rail 610 and extends in the longitudinal direction to prevent the moving member 301 from being disengaged.

The guide rail 610b is a lead-in portion, and the guide rail 610b includes an opening 621, and the opening 621 is formed in a part of the escape prevention jaw 612 constituting the upper surface of the guide rail 610 b. The opening 621 forms the escape prevention jaws 612 at both sides, thereby forming a space for introducing the moving member 301. At this time, both side portions may be closed in the longitudinal direction of the guide rail 610 b.

A holder member 622 is detachably attached to the opening 621. The holder member 622 can introduce the moving member 301 into the guide rail 610b via the opening 621 at the time of separation, and can prevent the introduced moving member 301 from being detached at the time of installation.

The opening 621 includes a through portion 621a and a step portion 621b, and the step portion 621b extends from the escape prevention jaw 612 at both sides in the longitudinal direction of the through portion 621a to form a step. The step 821b forms an installation space of the holder member 622. Opening portions 621 are formed at positions where the escape prevention jaws 612 are respectively opposite to both sides of the upper portion of the guide rail 610b, and a holder member 622 may be installed at each opening portion 621.

The holder member 622 includes an upper plate 622a and an engaging portion 622b. The upper plate 622a extends in such a manner as to block the guide rail 610b together with the escape prevention jaw 612. The engaging portion 622b is mounted on the step portion 621b and is used to fix the holder member 622. The holder member 622 allows the introduction of the moving member 301 connected to the moving part of the link mechanism 300 by separation and fixation, and can prevent the introduced moving member 301 from being detached.

When the moving member 301 is mounted on the guide rail 610b, the moving member 301 is assembled by being placed from the upper side to the lower side of the guide rail 610b, so that the assembly becomes easy, and the opening 621 constituting the introduction portion can be easily closed. Thereby, the moving member 301 of the link mechanism 300 can be easily introduced into the guide rail 610 b.

Fig. 8 is a view for explaining a third embodiment of a guide rail in the stowable massaging device of the invention.

The guide rail 610c according to the third embodiment shown in fig. 8 is formed differently in the opening 621 forming the introduction portion compared to the guide rail 610b according to the second embodiment shown in fig. 7. In describing the guide rail 610c according to the third embodiment, the same or similar parts as those of the guide rail 610b according to the second embodiment are omitted or briefly described.

Unlike the guide rail 610b shown in fig. 7, the opening 621 forming the introduction portion of the guide rail 610c is formed by a through portion 621a' that is open to the side of the guide rail 610 c.

The moving member 301 of the link mechanism 300 may be introduced into the sliding space 621b 'via the through portion 621 a'.

The holder member 622' is mounted on the opening 621. The holder member 622' is formed in such a manner that a first side plate 622a ' on the inner side of the guide rail 610c and a second side plate 622b ' on the outer side of the guide rail 610c are connected. A space capable of moving the moving member 301 is formed between the first side plate 622a 'and the second side plate 622 b'.

When the moving member 310 is mounted on the guide rail 610c, the moving member 301 can be assembled in the guide rail 610 by sliding the moving member 301 on one side of the guide rail 610, thereby facilitating assembly. In addition, by making the holder member 622' detachable from the side portion of the guide rail 610c, the opening 621 for constituting the introduction port is easily opened and closed. Thereby, the moving member 301 of the link mechanism 300 can be easily introduced into the guide rail 610 c.

The stowable massage device 10 of an embodiment of the present invention may include a driving part 500 that provides a driving force for driving the link mechanism 300. According to the stowable massaging device 10 of the present invention, the driving part 500 may include actuators 510a, 510b provided between the main body part 100 and the drawing part 200 and the link mechanism 300, and an actuator 510c connected to the rack and pinion gear 520, the main body part 100, the drawing part 200, and the moving part of the link mechanism 300.

Fig. 9 to 11 are views for explaining an actuator connected as a driving part in the stowable massage device according to an embodiment of the present invention. The setting position of the actuator is shown in fig. 9 and 10, and the second embodiment of the connection relationship of the actuator is shown in fig. 11.

As shown in fig. 9 and 10, the driving portion 500 is disposed between the link mechanism 300 and at least one of the main body portion 100 and the lead-out portion 200, and provides a driving force for driving the link mechanism 300.

The driving part 500 may include an actuator 510, one side of the actuator 510 being connected to at least one of the body part 100 and the lead-out part 200, and the other side thereof being connected to the link mechanism 300. The actuator 510 may adjust the length between one side and the other side thereof, thereby driving the linkage 300.

One side of the actuator 510 is connected to the main body 100 in the non-accommodating space 122 of the main body 100. The portion connected to one side of the actuator 510 may be the first inner frame 110 of the main body 100 disposed in the non-accommodating space 122 of the main body 100. The other side of the actuator 510 is connected to the linkage 300.

Fig. 9 shows a connection relationship between the main body 100 and the actuator 510. As shown in fig. 9, the actuator 510 may include a fixed body 511, a linear motor 512, and a moving rod 513. The fixed body 511 is formed in a hollow rod shape, and the moving rod 513 is provided to be movable toward the inside of the fixed body 511. The linear motor 512 is coupled to the fixed body 511 and drives the moving lever 513.

An end portion of the fixing body 511 for forming one end of the actuator 510 is connected to the connection member 516 through the hinge shaft 515. The connection member 516 may be connected to one of the first internal frames 110 within the non-receiving space 122 of the body part 100. One side of the actuator 510 is connected to the body portion 100 in the manner described above.

The connection relationship of the actuator and the link mechanism is shown in fig. 10, and referring to fig. 10, the other side of the actuator 510 may be connected to a partial region from one end to the other end of the link mechanism 300.

For example, when the link mechanism 300 has a form in which a plurality of link members 310, 320 are connected, the other end of the actuator 510 may be connected to the link shaft 351 of the link mechanism 300. In this case, the driving force of the actuator 510 can be more efficiently transmitted to the link mechanism 300. However, without being limited thereto, the other side of the actuator 510 is connected to a partial region between one end and the other end of the link mechanism 300, for example, between one end and the other end of the first link member 310 or between one end and the other end of the second link member 320.

According to an embodiment of the present invention, when the link mechanism 300 is formed of a single link member, for example, when the link mechanism 300 is formed of the first link portion 310 or the second link portion 320, one side of the actuator 510 is connected to one of the main body portion 100 and the lead-out portion 200, in which the hinge portion is formed.

In the case where the link mechanism 300 is constituted by the first link member 310, one side of the actuator 510 may be connected to the main body portion 100. The other side of the actuator 510 is connected to an arbitrary position between one end and the other end of the first link portion 310. In the case where the link mechanism 300 is constituted by the second link member 320, one side of the actuator 510 is connected to the lead-out portion 200. The other side of the actuator 510 is connected to an arbitrary position between one end and the other end of the second link part 320.

As described above, the other side of the actuator 510 is connected to a partial region from one end to the other end of the link mechanism 300, whereby the position of any one of the one end and the other end of the link mechanism 300 can be changed, so that the separation distance can be adjusted.

Referring to fig. 11, according to the second embodiment of the connection relationship of the actuators, the actuator 510b may be connected between the support portion 111a extending from the first link mounting portion 111 of the main body portion 100 and the link mechanism 300. The support portion 111a of the side to which the actuator 510b is connected may be provided to extend vertically from the first link mounting portion 111. The support 111a may be a part of the first inner frame 110.

The other side of the actuator 510b may be connected to any region of the linkage 300. For example, the other side of the actuator 510b may be connected between the link shaft 351 and the hinge portion in the first link portion 310 hinge-coupled to the first link mounting portion 110 of the body portion 100. In this case, the driving force of the actuator 510b can be more efficiently transmitted to the link mechanism 300.

Fig. 12 is a view for explaining an embodiment in which a driving unit in the stowable massaging device of the present invention is formed of a rack and pinion gear.

According to an embodiment of the invention, the driving part 500 may be formed of a rack and pinion gear (rack and pinion gear) 520. Referring to fig. 12, a case where a driving part formed of a rack and pinion gear 520 is provided at the main body part 100 is shown, but is not limited thereto. At least one moving part of the link mechanism 300 may guide its movement through the rack and pinion gear 520 so as to receive a driving force.

The rack and pinion gear 520 may include a rack 521 and a pinion 522.

The rack 521 may be provided at least one of the main body part 100 and the lead-out part 200. For example, the rack 521 may extend in the longitudinal direction of the first link mounting portion 111 of the main body portion 100, or may extend in the longitudinal direction of the second link mounting portion 211 of the lead portion 200.

Pinion 522 is connected to linkage 300 and is movable along rack 521. The pinion 522 is connected to a moving portion of the link mechanism 300, and is rotated by a driving motor (not shown). The pinion 522 changes the position of one end portion of the link mechanism 300 by being connected to the one end portion of the link mechanism 300, thereby adjusting the separation distance between the main body portion 100 and the lead-out portion 200. For example, the moving portions of the first link member 310 and the second link member 320 reciprocate along the longitudinal direction of the first link mounting portion 111 and the second link mounting portion 211 according to the rotation direction of the pinion gear 522.

Fig. 13 is a view for explaining an embodiment in which a driving part in the stowable massage device of the present invention is formed of an actuator connected to a moving part of a link mechanism.

Referring to fig. 13, the driving part 500 may include an actuator 510c, one side of the actuator 510c being connected to any one of the body part 100 and the lead-out part 200, and the other side thereof being connected to the moving part of the link mechanism 300, so that length adjustment between the one side and the other side is possible. The actuator 510c provides a force that directly supports the moving portion of the link mechanism 300 while moving it. Therefore, a guide rail or the like for guiding the movement of the moving portion of the link mechanism 300 may not be provided. However, the provision of guide rails is not precluded.

The actuator 510c may be provided to extend in the longitudinal direction in at least one of the first link mounting portion 111 and the second link mounting portion 211 of the main body portion 100 and the lead portion 200. One side of the actuator 510c is fixed to a side support portion 111b connected to one side of the first link mounting portion 111, and the other side thereof is fixed to a moving portion or any one of moving portions of each of the first link member 310 and the second link member 320. The moving portion of the first link member 310 and/or the second link member 320 can reciprocate along the length direction of the first link mounting portion 111 and the second link mounting portion 211 by driving of the actuator 510 c.

When the link mechanism 300 is formed of a single link member, for example, when the link mechanism 300 is formed of the first link member 310 or the second link member 320, the moving portion may directly support and drive the link mechanism 300 through the actuator 510 c.

When the link mechanism 300 includes the first link member 310 and the second link member 320 and is formed of a plurality of link members, either one of the moving parts may be directly supported by the actuator 510c, and the other moving part may be guided by a guide rail.

As described above, the other side of the actuator 510c is connected to one end of the link mechanism 300 and changes the position of one end of the link mechanism 300, so that the separation distance between the main body portion 100 and the lead-out portion 200 can be adjusted.

According to the stowable massaging device 10 of the present invention, in the driving section 500, the actuator 510 connected between the main body section 100 or the drawing section 200 and the link mechanism, the rack and pinion gear 520, and the actuator 510c connected to the main body section 100 or the drawing section 200 and the moving section may be combined to the first link mounting section 111 and the second link mounting section 211 in any manner and used. The guide rails 610, 610b for guiding the movement of the moving part of the link mechanism 300 may be applied according to the form of the driving part 500.

For example, the rack and pinion gear 520 or the actuator 510c may be applied to the first link mounting portion 111, and the guide rails 610, 610b may be applied to the second link mounting portion 211.

The stowable massage device 10 according to an embodiment of the present invention may include one or more wheels for guiding the movement of the lead-out portion 200 with respect to the main body portion 100.

Fig. 14 is a view for explaining wheels for facilitating movement of the drawing portion with respect to the main body portion in the stowable massage device according to the embodiment of the present invention.

Wheels for guiding movement of the lead-out portion 200 may be provided at least one of the side surfaces and the bottom surface of the lead-out portion 200.

Wheels (not shown) provided on the bottom surface of the lead-out portion 200 contact the ground (or floor) and perform rolling motion. The wheel supports the lead-out portion 200 to move relative to the ground, and the support lead-out portion 200 moves relative to the main body portion 100 via the link mechanism 300.

Referring to fig. 4 and 14, wheels 231, 232 for guiding movement of the lead-out portion 200 may also be disposed at the side of the lead-out portion 200. The wheels 231, 232 formed at the sides of the lead-out portion 200 are in contact with the main body portion 100 and perform rolling motion. According to an embodiment of the invention, the wheels 231, 232 may be formed by casters or the like.

The first extension 221 may extend from the second upper wall 201 of the lead portion 200 toward the main body portion 100. The second extension 222 may extend from the second lower wall 202 of the lead-out portion 200 toward the main body portion 100 side. The first extension 221 extends in the width direction inside the first upper wall 101 of the main body portion 100. The second extension 222 extends in the width direction inside the first lower wall 102 of the main body 100.

The wheels 231, 232 may include a first wheel 221 supporting the lead-out portion 200 for movement relative to the first upper wall 101 of the body portion 100, and a second wheel 222 supporting the lead-out portion 200 for movement relative to the first lower wall 102 of the body portion 100. The wheels 231, 232 are disposed toward the main body portion 100 at the lead-out portion 200, and are disposed in contact with the inner side surfaces of the first upper wall 101 and the second lower wall 102 of each main body portion 100 and perform rolling movement.

The first wheel 221 is mounted in such a manner that the first extension 221 contacts the inner side surface of the first upper wall 101 of the main body 100. The second wheel 222 is mounted in such a manner that the second extension 222 contacts the inner side surface of the first lower wall 102 of the main body 100. By the first wheel 231 and the second wheel 232, friction of the lead-out portion 200 with respect to the main body portion 100 can be minimized, thereby facilitating storage and lead-out of the main body portion 100.

According to an embodiment of the present invention, the linkage is formed by linkage 300b in an overlapped configuration.

Fig. 15 (a) and (b) are operational state diagrams of an embodiment of a superimposed link mechanism of a stowable massage device according to an embodiment of the present invention, and fig. 16 (a) and (b) are top and bottom views of an example of a superimposed link mechanism of a stowable massage device according to an embodiment of the present invention.

Referring to fig. 15 and 16, the linkage of an embodiment of the present invention may be formed of a plurality of linkages 300b connected, overlapped, and extended. For example, the overlapped link mechanism 300b is a link mechanism having a first link member 310 and a second link member 320, and in which a plurality of link mechanisms 300 having a single link shaft 351 are connected.

The linkage 300b may include not only the first and second link members 310 and 320 of the linkage 300, but also, for example, the third and fourth link members 330 and 340. The third link member 330 forms an axial connection with the first link member 310. One end of the fourth link member 340 forms an axial connection with the second link member 320.

Irrespective of the number of link members forming the link mechanism 300b, the link mechanism 300b includes two connection portions at one end region thereof, i.e., includes the first connection portion 311 and the third connection portion 321, and includes two connection portions at the other end region thereof, i.e., includes the second connection portion 312 and the fourth connection portion 322.

The first connection portion 311 formed at one end region of the link mechanism 300b and disposed upward is hinge-connected to the first link mounting portion 111, and the fourth connection portion 322 formed at the other end region of the link mechanism 300b and disposed upward is hinge-connected to the second link mounting portion 211.

The third connecting portion 321 formed at the other end region of the link mechanism 300b and disposed downward is movably connected to the first link mounting portion 111 in the length direction, and the second connecting portion 312 formed at the other end region of the link mechanism 300b and disposed downward is movably connected to the second link mounting portion 211.

In the embodiment shown in fig. 15 and 16, the first connection portion 311 is formed at one end of the first link member 310, the third connection portion 321 is formed at one end of the second link member 320, the fourth connection portion 322 is formed at one end of the third link member 330, and the second connection portion 312 is formed at one end of the fourth link member 340.

The first link member 310 and the second link member 320 cross about the link shaft 351, and the third link member 330 and the fourth link member 340 cross about the second link shaft 352. When the link mechanism 300b expands and contracts, the link shaft 351 and the second link shaft 352 may have a movement path parallel in the length direction, and may be configured to be substantially the same in the width direction. Accordingly, the link mechanism 300 supports the lead portion 200 to move relative to the main body portion 100 with substantially the same action as in the case of being formed of the first link member 310 and the second link member 320.

When the protrusion amount of the lead portion 200 is the same, the overlap type link mechanism 300b can use a shorter stroke when using the actuator, compared to the single link mechanism 300 having the link shaft 351 described above. Therefore, the time for which the lead portion 200 is led out can be shortened. The case where the length of each link member of the link mechanism 300b is short is shown in part (a) of fig. 15, and the case where the length of each link member of the link mechanism 300b is long is shown in part (b) of fig. 15. When the length of each link member of the link mechanism 300b is long, both the upper and lower portions of the lead-out portion 200 are held, and thus can be driven more stably, than when the length of each link member of the link mechanism 300b is short.

According to an embodiment of the present invention, the actuator mounting part 360 may be mounted at the link shaft 351 where the first link member 310 and the second link member 320 cross. One side of the actuator 510d for driving the linkage 300b may be mounted at the actuator mounting part 360. One end of the actuator 510d may be fixed to the link shaft 351. The other end of the actuator 510d is connected to the third link member 330, and may be connected to a region between the third link member 330 and the second link shaft 352.

The link shaft 351 and the second link shaft 352 of the link mechanism 300b may be disposed at an upper portion of the lead portion center axis l. In the upper and lower mounting positions of the first link mounting portion 111 and the second link mounting portion 211 to which the link mechanism 300b has been mounted, the third connecting portion 321 of the second link member 320 movably mounted to the first link mounting portion 111 and the second connecting portion 312 of the fourth link member 340 movably mounted to the second link mounting portion 211 may be formed on the lower mounting positions of the first link mounting portion 111 and the second link mounting portion 211.

That is, one side of the second link member 320 is movably coupled to the lower mounting position of the first link mounting part 111, and the other side thereof is hinge-coupled to the fourth link member 340. One side of the fourth link member 340 is hinge-coupled to the second link member 320, and the other side thereof is movably coupled to a lower mounting position of the second link mounting portion 211.

Therefore, the height from the lead portion center axis l to the link shaft 351 (also applied to the second link shaft 352) when the link mechanism 300b is extended is located further upward than the height from the lead portion center axis l to the link shaft 351 when the link mechanism 300b is contracted. When the link mechanism 300b is extended, the lower ends of the second link member 320 and the fourth link member 340 located at the lower portion of the lead-out portion central axis l are moved to the upper sides of the first link mounting portion 111 and the second link mounting portion 211. Therefore, when the link mechanism 300b is extended, the position of the link shaft 351 rises.

The link mechanism 300b may be connected such that the link shaft 351 is disposed at an upper portion of the lead portion central axis l both when the link mechanism 300b is contracted and when it is extended. When the link mechanism 300b is extended (when the drawing portion 200 is drawn), the height from the drawing portion central axis l to the link shaft 351 is raised higher than the height from the drawing portion central axis l to the link shaft 351 when contracted.

Accordingly, the overlapped link mechanism 300b can adjust the separation distance between the body part 100 and the lead-out part 200 by pushing and pulling the region corresponding to the center of gravity of the lead-out part 200, whereby the stability of the stowable massaging device 10 can be ensured.

Fig. 17 is a diagram for explaining an example in which a control module is provided in the stowable massaging device of the present invention.

Referring to fig. 17, the stowable massage device 10 according to the present invention may include a control module 700 for controlling the linkage mechanisms 300, 300 b. The control module 700 controls the driving of the link mechanisms 300, 300 b. The control module 700 may be formed in a button form, but is not limited thereto. The control module 700 may be provided at any portion of the main body portion 100 and the lead portion 200 exposed to the outside. For example, the control module 700 may be disposed at the fourth sub-sidewall 203b in the second sidewall 203 of the lead-out portion 200.

Specifically, as shown in fig. 17, the control module 700 may be provided in a central portion region of the fourth side wall 203b, but is not limited thereto, and may be provided in a portion of the main body portion 100 and the lead-out portion 200 exposed to the outside, for example, at least a portion of at least one of the first upper wall 101, the first lower wall 102, the first sub-side wall 103a, or the second upper wall 201, the second lower wall 202, and the fourth sub-side wall 203b of the main body portion 100.

Control module 700 may include an enter (IN) button 710, a LOCK (LOCK) button 720, and an exit (OUT) button 730. The enter (IN) button 710 is a button for storing the lead portion 200 IN the internal space 110 of the main body portion 100 by contracting the link mechanisms 300, 300 b. The LOCK button 720 is a button for locking or unlocking the contraction or expansion of the link mechanisms 300, 300 b. The exit (OUT) button 730 is a button for extending the link mechanisms 300 and 300b to draw the second frame 200 OUT of the main body 100. When the user presses each of the buttons, the control module 700 controls the driving part 500 in response to the input of the user, whereby the driving part 500 may be extended or contracted, or the action of the driving part 500 may be locked or released.

The control module 700 may include an LED (LIGHT EMITTING Diode) 740 that operates in conjunction with the button. At this time, the LED 740 may be disposed at an upper portion of each button of the control module 700. For example, LED 740 is located on LOCK button 720 and may be illuminated when LOCK is activated. The link mechanisms 300, 300b are initially IN a locked state, and when the user presses the lock button 720 for a predetermined time (for example, 3 seconds), the lock of the link mechanisms 300, 300b is released, and the enter (IN) button 710 and the exit (OUT) button 730 are activated.

When the user presses the enter (IN) button 710 or the exit (OUT) button 730 only once, the lead-OUT portion 200 is drawn into the main body portion 100 or is led OUT from the main body portion 100. When the driving part 500 operates, if only one of the enter (IN) button 710, the LOCK (LOCK) button 720, and the exit (OUT) button 730 is pressed, the driving part 500 stops operating. After the operation of the driving unit 500 is stopped, the arbitrary buttons 710, 720, 730 need to be pressed again in order to perform the next operation again. On the other hand, the lock state may be automatically activated. For example, the locked state is activated when the user presses any of the buttons 710, 720, 730 in rapid succession.

Referring to fig. 18, the stowable massage device 10 may include at least a portion of a remote controller 1, a socket 2, a PCB (Printed circuit board; printed circuit board) 3, and a control module 700.

The remote controller 1 is used to control the driving of the massage module 400. However, the present invention is not limited thereto, and the user may operate the driving unit 500 by operating the remote controller 1. In this case, the extraction and storage of the extraction portion 200 with respect to the main body portion 100 can also be controlled.

The PCB 3 may control the actions of the driving part 500 and the massage module 400. For example, the PCB 3 may be connected to the control module 700 and the driving part 500 by wire and wirelessly. In addition, for example, the PCB 3 may drive the driving part 500 according to a signal input from the control module 700, and may control the massage module 400 according to a signal received from the remote controller 1.

The socket 2 may be provided inside the first upper wall 101 of the body portion 100. The wires of the socket 2 extend to the outside of the stowable massage device 10 and then are connected to another power source. The massage part power supply line q of the massage module 400 provided at the lead-out part 200 extends from the lead-out part 200 along the inside of the first upper wall 101 of the main body part 100 and is connected to the socket 2.

The actuator power cord p is connected to the socket 2 without interfering with the linkage mechanisms 300, 300 b. The signal line r of the control module 700 connected to the lead-out portion 200 extends from the lead-out portion 200 to the inside of the first lower wall 102 of the main body portion 100, and is then connected to the PCB 3. Thus, interference with the link mechanisms 300, 300b is prevented. In order to prevent the massage part power supply line q, the actuator power supply line p, and the signal line r from being dragged or damaged by gears, a cable tray, a package, or the like may be used.

The PCB 3 may be provided in one or more pieces, and may be provided in the non-storage space 122 of the main body portion 100 or in the inner space of the lead portion 200 at the lower portion (portion supporting the lower body portion of the user) of the opening portion 204a where the massage module 1000 of the lead portion 200 moves in order to prevent interference with the link mechanisms 300, 300 b. However, not limited thereto, the PCB 3 may be provided in any space inside the main body portion 100 and the lead-out portion 200 other than the space accommodating the link mechanisms 300, 300 b.

Referring to fig. 19, according to an embodiment, the position of the socket 2 may be located at the outer surface of the first upper wall 101 of the body part 100, or may be located at the outer surface of the first lower wall 102 of the body part 100. Or the socket 2 may be provided in the inner space of the first upper wall 101 and the first lower wall 102. Or the socket 2 may be provided at least one of the outer surface of the first upper wall 101, the outer surface of the first lower wall 102, and the inner spaces of the first upper wall 101 and the first lower wall 102.
