Description

{ADJUSTABLE LENGTH TOY SWORD}

The present invention relates to a toy sword with adjustable length, and more specifically, to a toy sword with adjustable length, in which a wire is connected to a gear portion, and a plurality of parts are spaced apart from each other or adjacent to each other in response to winding and unwinding of the wire to form a sword blade portion whose length is adjusted, and a driving portion that operates the gear portion according to the length of the sword blade portion is made to rotate idling to prevent damage to the gear portion.

Typically, sword toys are made of plastic with a handle and a sword protruding from the handle to a certain length, and are used when children play sword games by dividing into teams and swinging the sword toy.

However, the problem with sword fighting is that it often causes safety accidents in which children get injured as they become more aggressive, and it also has a negative impact on children's emotions.

Accordingly, a conventional sword toy has an LED bar inside the sword that operates with a button, and a control board, a battery compartment, and a button are provided inside the handle, so that when the button is pressed, the LED bar inside the sword flashes. In addition, a sword toy that is safe and fun has been provided by making it possible for a single player to play swordfight by generating a sound when the swords collide.

However, these knife toys do not have uniform lighting and only repeat the same sound, making them monotonous. In addition, they are not fun, so children easily lose interest.

Provides a toy sword with adjustable length.

In an embodiment of the present invention, the above-described frame part may be characterized in that it is accommodated in the center of the parts and can respond to the bending mode of the second to n-th parts when the length is expanded by spacing out the second to n-th parts.

In an embodiment of the present invention, the blade portion may be characterized in that one side of the part forms an inclined portion having at least one step and a raised center, and the other side of the second to nth parts forms a concave portion corresponding to the inclined portion, so that the first to nth parts are respectively coupled to the inclined portion and the concave portion.

In an embodiment of the present invention, the length adjusting unit may be characterized in that when one side of the wire is unwound from the first roller plate along the longitudinal direction of the blade portion, the other side of the wire is wound around the second roller plate, and the tube accommodated in the part slides to sequentially separate the second to nth parts.

In an embodiment of the present invention, the length adjusting member may further include a stopper that forms flanges on both sides of the tube pipe, has one side accommodated inside the hole, and is positioned on an outer surface of the part communicating with the hole, so that when the tube pipe slides along the hole, the flange comes into close contact with the outer surface of the part to control movement of the part.

In an embodiment of the present invention, the gear section may further include roller gears formed on one surface of the first roller plate and one surface of the second roller plate, respectively; a main gear formed with a diameter larger than the roller gears and rotatably connected to the inside of the seal to rotate the roller gears; and a protruding gear protruding toward each facing surface of the main gear to rotate the main gear in response to the rotation of the driving section.

In an embodiment of the present invention, the gear portion may further include a twist-preventing wall portion formed between the circumference of the first roller plate and the second roller plate and the shaft connecting the main gear to separate the wire from the shaft.

In an embodiment of the present invention, the driving unit may further include an extension portion forming a grip portion and extending from one side of the grip portion and accommodated inside the seal; a grip gear formed on one side of the extension portion and connected to the protruding gear and having the other side formed to rotate on one side inside the extension portion; a receiving groove formed with a concave groove on the other side of the grip gear; and a lower gear portion connected to the receiving groove and controlling the rotation of the grip gear.

As illustrated in FIG. 1, a toy sword (10) with adjustable length according to an embodiment of the present invention includes a blade part (100), a length adjustment part (200), a gear part (300), and a driving part (400).

More specifically, as illustrated in FIGS. 1 and 2, a toy sword (10) with adjustable length according to an embodiment of the present invention includes a sword frame portion (110) extending from one side of a sword guard (11), a sword blade portion (100) connecting first to nth parts (120) separated by an axis of the sword frame portion, a tube tube (210) formed in a sliding manner in a through-hole (130) formed on both sides of the parts, and a length-adjusting portion (200) that separates and adjacent the parts by the movement of the tube tube in response to the movement of a wire (220) accommodated in the tube tube, a gear portion (300) configured to wind and unwind the wire, the first roller plate (310) accommodated inside the sword guard and having one end of the wire wound around it and a second roller plate (320) having the other end of the wire wound around it, and a driving portion (400) positioned on the other side of the sword guard and operating the gear portion.

Referring to Fig. 1, the sword guard (10) is positioned between the toy sword and the handle to prevent the opponent's sword blade from injuring the hand during a sword fight. In addition, the sword guard (10) is formed as a cover that is separated into two sides, and forms a receiving space for accommodating the gear part (300) of the present invention inside the cover on one side.

In addition, the shield (10) may have a PCB board inside, and a button for forming an LED module on the PCB board to light up the LED module may be provided on one side of the handle. To this end, a control unit for controlling power supply to the PCB board is provided and connected to the button.

In addition, the seal (10) may be expressed simply or its specific shape may be omitted in order to clearly explain the operating principle and the coupling relationship between the components of the embodiment of the present invention in the drawings of the specification herein.

Referring to Fig. 1, the blade part (100) is connected to a blade frame part (110) extending from one side of the blade cover (11) and first to nth parts (120) separated by an axis from the blade frame part (110).

The sword frame part (110) is received in a first part (120) that is firmly connected to one side of the sword curtain (11) and extends in one direction. Then, the first to n-th parts (120) are formed with a length that is adjacent to each other, and the terminal part is received inside the n-th parts (120).

Referring to FIG. 2, the sword frame part (110) is accommodated in the center of the part (120) and functions to respond to the bending mode of the second to nth parts when the length is expanded by spacing out the second to nth parts.

For example, when parts (120) made of multiple pieces are spaced apart at regular intervals to form a space between them, the weight and centrifugal force of the parts (120) located at a distance away from the sword barrier (11) may cause them to bend. Accordingly, the spaced apart parts of each part (120) are supported by the sword frame (110) to enable children to play sword fighting.

Referring to FIGS. 2 and 3, the parts (120) form the appearance of a blade extending in the longitudinal direction and are separated at a certain interval or at a desired interval according to the shape of the blade and connected to each other.

In addition, the part (120) forms a guide hole (121) that penetrates the center flatly in response to the shape of the sword frame part (110). The guide hole (121) enables the separated part (120) to slide along the length of the sword frame part (110).

The perforation (130) is formed to receive a tube (210) that will be described later by penetrating both sides of the part (120), and to form a hole through which the tube (210) can slide. As a result, when the parts (120) are separated and spaced apart, the central part of each part (120) that has been separated is supported by the frame part (110), and both sides of the part (120) can be supported by the tube (210).

In addition, the hole (130) is formed so that the diameter of the inner center is wider than the diameters of the two sides exposed to the outside of the part (120), thereby forming a step. In addition, among the stoppers (230) formed on both sides of the tube pipe (210) described below, one stopper (230) enables the part (120) to move in response to the moving direction of the tube pipe (210).

Meanwhile, as illustrated in FIG. 3, it is preferable that the blade portion (100) has one side of the part (120) formed with an inclined portion (140) that has at least one step and a raised center, and that the other side of the second to nth parts (120) corresponding to the inclined portion (140) forms a concave portion (150), so that the first to nth parts (120) are respectively coupled to the inclined portion (140) and the concave portion (150).

In particular, the blade part (100) can have its length varied by expanding the length by spacing out the first to nth parts (120) along a straight line, and then reducing the length by placing each part (120) adjacent to each other.

In this case, when the length is varied, as shown in FIGS. 1 and 2, the inclined portion (140) formed on one side of the first part (120) is received and pressed into the concave portion (150) formed on the other side of the second part (120). As a result, the center of the first part (120) is pressed into the second part, and both sides of the second part (120) surround both sides of the first part (120) to form a strong sealing force.

Referring to FIGS. 3 and 4, in a toy sword (10) with adjustable length according to an embodiment of the present invention, a length-adjusting portion (200) forms a tube (210) that is slidably received in a hole (130) formed on both sides of a part (120), and functions to separate and adjacent parts (120) by moving the tube (210) in response to the movement of a wire received in the tube (210).

The tube (210) is positioned inside the hole (130) and slides in response to the movement of the wire (220) wound and unwound on the gear part (300). In addition, the tube (210) assists and supports the sword frame part (110) that supports a plurality of parts (120) that are separated and spaced apart. As a result, the phenomenon of the blade part (100) having an extended length being bent can be prevented.

The wire (220) is formed with a length corresponding to the distance separating the plurality of parts (120) and the length wound around the gear part (300). Then, by the operation of winding and unwinding around the gear part (300), the tube (210) is pushed or pulled to bring the plurality of parts (120) adjacent to each other or apart from each other.

In addition, the wire (220) forms a covering tube (221) that protects the surface and is accommodated inside the tube tube (210), enabling the tube tube (210) to move in response to the movement of the wire (220).

In this way, the length adjustment unit (200) is configured such that when one side wire (220) is unwound from the first roller plate (310) along the longitudinal direction of the blade part (100), the other side wire (220) is wound on the second roller plate (320), and the tube (210) accommodated in the part (120) slides to sequentially separate the second to nth parts (120).

Meanwhile, as shown in FIGS. 3 and 4, the length adjustment part (200) further includes a stopper (230).

The stopper (230) forms flanges on both sides of the tube pipe (210), has one side accommodated inside the hole (130), and is positioned on the outer surface of the part (120) communicating with the hole (130). When the tube pipe (210) slides along the hole (130), the flange is in close contact with the outer surface of the part (120) to control the movement of the part (120). Here, a detailed description of the stopper (230) is given with reference to the gear section (300) described below.

Referring to FIGS. 3 and 4, in the toy sword (10) with adjustable length according to an embodiment of the present invention, the gear part (300) is comprised of a first roller plate (310) that is accommodated inside the sword cover (11) and winds one end of a wire (220) and a second roller plate (320) that is winds the other end of the wire (220), and serves to wind and unwind the wire (220).

Here, the first and second roller plates (310, 320) are formed as discs and are formed in a reel shape capable of winding a wire (220) on one end surface. Then, they are laminated and rotatably connected to a shaft formed inside the covers on both sides forming the screening (11).

In particular, one end of the wire (220) is wound around a first roller plate (310) and the other end of the wire (220) is wound around a second roller plate (320). When one end of the wire (220) is wound by the rotation of the first roller plate (310), the second roller plate (320) rotates to wind the other end of the wire (220).

At this time, as shown in (b) of Fig. 4, the tube (210) located on one side of each part (120) that receives the one-sided wire (220) moves toward the concave portion (150) of the second part (120), and the stopper (230) pushes the hole (130) located in the concave portion (150).

In addition, the other side wire (220) is wound around the second roller plate (320), but due to the pushing force of the tube tube (210) located on one side, the tube tube (210) located on the other side moves in the same direction as the tube tube located on one side, and only the other side wire (220) is wound around the second roller plate (320). As a result, the second to n-th parts (120) are sequentially separated to extend the length of the blade part (100).

In addition, when the separated and spaced parts (120) are brought into close contact with each other, the wire (220) on one side is wound around the first roller plate (310). As a result, the tube (210) located on one side of each part (120) moves in the direction of the inclined portion (140) of the n-1th part (120) from the inside of the through-hole (130) of the nth part (120). In addition, the stopper (230) located inside the through-hole (130) of the nth part (120) moves the nth part (120) adjacent to the n-1th part (120).

In this way, by sequentially and closely contacting the nth to 1st parts, the blade part (100) whose length has been extended can be reduced.

To this end, as shown in Fig. 5, the gear part (300) further includes a roller gear (330), a main gear (340), and a protruding gear (350).

The roller gear (330) is formed on one side of the first roller plate (310) and one side of the second roller plate (320).

The main gear (340) is formed with a diameter wider than that of the roller gear (330) and is rotatably connected to the inside of the seal (11) to rotate the roller gear (330). The main gear (340) is positioned so that a portion of its diameter is laminated on each surface of the first and second roller plates (310, 320) to provide rotational force to the roller gear (330).

The protruding gear (350) is a gear that protrudes toward each facing surface of the main gear (340) and rotates the main gear (340) in response to the rotation of the driving unit (400).

In other words, the protruding gear (350) faces each side of the main gear (340) and protrudes in the axial direction that rotatably connects the main gear (340). And, it is connected to the grip gear (430) formed on one side of the driving unit (400).

At this time, when the driving unit (400) is rotated about the longitudinal axis, the grip gear (430) rotates to rotate the protruding gears (350) connected to both sides of the grip gear (430). The main gear (340) rotates in response to the rotational direction of the protruding gear (350), and the roller gear (330) connected to the main gear (340) rotates to rotate the first and second roller plates (310, 320).

Meanwhile, as illustrated in Fig. 1, the gear portion (300) may further include an anti-twist wall portion (360).

The anti-twist wall (360) is formed between the circumference of the first roller plate (310) and the second roller plate (320) and the shaft connecting the main gear (340) and serves to keep the wire (220) away from the shaft.

For example, when one end of a wire (220) is wound around a first roller plate (310), the other end of the wire (220) unwound from the second roller plate (320) may become loose and move away from the second roller plate (320) in the axial direction of the main gear (340). As a result, the other end of the wire (220) may become entangled in the protruding gear (350), causing the wire (220) to break or the protruding gear (350) to be damaged. To improve this problem, it is preferable to form a twist-preventing wall portion (360).

Referring to FIGS. 6 and 7, in the toy sword (10) with adjustable length according to an embodiment of the present invention, the driving unit (400) is located on the other side of the sword cover (11) and serves to operate the gear unit (300).

To this end, the driving unit (400) further includes an extension unit (410), a grip gear (420), a receiving groove (430), and a lower gear unit (440).

The extension (410) forms a grip portion (12), and is extended from one side of the grip portion (12) and received so as to be rotated into the interior of the seal (11). That is, a groove is formed along a circumference on one side of the grip portion (12), and a protrusion is formed on the other side of the seal (11) corresponding to the groove formed in the grip portion (12), so that the protrusion is fastened to the groove and the grip portion (12) can be rotated about the longitudinal axis. As a result, rotation of the extension portion (410) becomes possible.

In addition, the extension (410) forms a connecting hole (411) extending longitudinally through both sides of the outer surface, and a rotating body (442) described later can be fastened to the connecting hole (411) to rotate the grip gear (420).

Referring to FIGS. 6 and 7, the grip gear (420) is formed on one side of the extension (410) to be connected to the protruding gear (350) and the other side is formed to rotate on one side inside the extension (410). That is, the grip gear (420) forms an axial shaft inserted into the inside of the extension (410), and a gear is formed on one side of the axial shaft to be connected to the protruding gear (350). In addition, an axial shaft rotating body having a diameter wider than the axial shaft is formed on the other side of the axial shaft to form a step.

The receiving groove (430) is formed as a concave groove on the other side of the grip gear (420), and a groove is formed along the diameter, and an inclined surface is formed on both sides of the groove to which the lower gear part (440) described later is connected.

Referring to FIGS. 6 and 7, the lower gear part (440) is connected to the receiving groove (430) and serves to control the rotation of the grip gear (420).

For this purpose, the lower gear part (440) includes a rotating shaft part (441), a rotating body (442), and a spring (443).

The rotating shaft (441) forms a shaft connected to the other side of the grip gear (420), and forms a support (441a) in which the end of the shaft is rotatably connected to one side of the grip (12)). The support (441a) supports a spring (443) accommodated in the lower part of the rotating body (442), thereby enabling the rotating body (442) to move linearly back and forth by the tension action of the spring (443).

The rotating body (442) forms an inclined projection (442a) protruding on one side corresponding to the receiving groove (430), and rotates the grip gear (420) corresponding to the one-way rotation of the grip portion (12) to operate the gear portion (300).

The inclined projection (442a) enables one side of the rotating body (442) to be firmly connected to the other side of the grip gear (420), thereby transmitting the rotational power of the rotating body (442) to the grip gear (420).

Additionally, the rotor (442) may further include a coupling projection (442b).

The coupling protrusion (442b) is a protrusion that protrudes on both sides of the outer surface of the rotating body (442) corresponding to the coupling hole (411). This coupling protrusion (442b) is fastened to the coupling hole (411) so that the rotating body (442) can rotate according to the rotation of the extension part (410). Therefore, when the extension part (410) rotates corresponding to the one-way rotation of the grip part (12), the rotating body (442) can rotate and the grip gear (420) can rotate.

Referring to Fig. 7, a spring (443) has one end received on the other end of a rotating body (442) and the other end connected to one surface of a support member (441a), and applies a force to push the rotating body (442) into the receiving groove (430).

In particular, when the spring (443) separates and contacts the parts (120), it plays a role in causing the rotating body (442) to rotate idly by the linear reciprocating movement of the rotating body (442) in which the inclined projection (442a) is received and separated in the receiving groove (430).

That is, when the grip part (12) is rotated while the length of the blade part (100) has been expanded and reduced, and the rotation of the grip gear (420) has stopped, the inclined projection (442a) formed on the rotating body (442) moves away from the receiving groove (430) along the inclined surface formed in the receiving groove (430) to move the rotating body (442) toward the support part (441a).

At this time, as shown in (b) of Fig. 7, the spring (443) is compressed to push the rotating body (442) as shown in (a) of Fig. 7 so that the inclined projection (442a) is received in the receiving groove (430). Then, when the grip part (12) is continuously rotated, as described above, the rotating body (442) is moved back and forth in a straight line by the tension action of the spring (443) to cause idle rotation.

For example, as shown in Fig. 1, when the grip portion (12) is rotated in one direction to separate a plurality of parts (120) to expand the length of the blade portion (100) or to bring the parts (120) adjacent to each other to reduce the length of the blade portion (100), the movement of the parts (120) stops and the operation of the gear portion (300) stops.

At this time, when the grip part (12) is continuously rotated in one direction, as shown in Fig. 5, excessive force is applied to the protruding gear (350) connected to the grip gear (420) due to the rotation of the grip gear (420), which may cause the protruding gear (350) and the grip gear (420) to be damaged.

In addition, since rotational force is provided to the main gear (340) connected to the protrusion gear (350), excessive force is also applied to the roller gear (330) connected to the main gear (340), so there is a possibility that the main gear (340) and the roller gear (330) may also be damaged.

In order to improve this problem, when the operation of expanding or reducing the length of the blade part (100) is completed, as described above, the rotating body (442) is made to rotate idly to stop the rotational force applied to the grip gear (420), and the operation of the gear part (300) is also stopped to prevent damage to the gear part (300).

As described above, the detailed description of the present invention has described preferred embodiments of the present invention, but this has been described as an example of the best embodiment of the present invention and does not limit the present invention. In addition, it goes without saying that anyone with ordinary knowledge in the technical field to which the present invention belongs can make various modifications and imitations within the scope that does not depart from the technical idea of the present invention.

Therefore, the scope of the present invention is not limited to the above-described embodiments, but can be implemented in various forms of embodiments within the scope of the appended claims. In addition, it is considered that various modifications can be made by anyone with ordinary skill in the art to which the invention pertains without departing from the gist of the present invention claimed in the claims, and are within the scope of the claims of the present invention.
