Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an armrest of a connecting chair.

[0002]

2. Description of the Related Art In a facility such as a hall, a movie theater, a theater, a conference hall, a stadium, and the like, a connecting chair for connecting a large number of chair bodies to the left and right is installed. As for the connecting chair, one elbow is shared between adjacent seats. The upper surface of the elbow is generally composed of a flat surface, and its width is almost 50 mm.
It was about.

[0003]

However, in the conventional armrest device for a connected chair, the upper surface is flat and the narrow elbow is used. Therefore, it is difficult for two persons in the adjacent seat to use the elbow at the same time. Yes, even if two people in the seats next to each other used elbows, their elbows and arms touched each other, causing discomfort. On the other hand, by increasing the width of the elbow, it becomes easier for two persons next to the elbow to use the elbow at the same time, but in this case the elbows and arms of each other are still touching, and the wide elbow is the seat of the occupant. It interferes with the sitting and standing motions. Furthermore, since there is no distinction between left and right elbows, it is unclear which of the left and right occupants should use the elbows,
It was difficult to use the elbow trees without hesitation.

[0004] These problems can be solved to some extent by increasing the width of the elbow, but without considerably increasing the width, it is impossible to prevent contact with the arm or elbow of a person in the next seat. Also, if the width of the elbow is widened, the number of seats must be reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an armrest of a connected chair which can make the boundary between adjacent seats clear and can prevent contact between the elbows and arms.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the first aspect of the present invention, there is provided an armrest of a connecting chair in which a plurality of chair bodies are connected side by side and an elbow is shared between adjacent seats. A partition wall is provided. Therefore, the left and right borders of the elbow resting surface of the elbow tree become clear, and the areas to be used by the left and right occupants become clear. Also, the partition wall prevents contact between the elbows and arms.

Here, the partition wall may be formed integrally with the elbow, or may be formed separately and fixed by bonding, screwing, fitting, or the like, or movable with a hinge, a shaft, a guide, or the like. It may be connected in some way. Further, the partition wall does not need to be formed continuously over the entire area in the depth direction of the elbow, and may be formed intermittently in the depth direction, or may be provided partially, for example, in a portion near the back of the seat. . Furthermore, it is also possible to make a part of the elbow tree foldable in the width direction so that the elbow rest surface can be expanded at the time of use. Further, the partition wall may be installed floating from the elbow, or may be installed on the backrest of the chair body and installed on the elbow.

[0008] For example, as in the second aspect of the present invention, the elbow is superposed on the substrate so as to sandwich the partition wall with the vertically protruding partition wall and is connected to the substrate so as to be reversible in the width direction. The elbow support surface is expanded by reversing the auxiliary plate in the width direction, and at the same time, the partition wall is projected. In this case, the width of the elbow is narrowed by folding the auxiliary plate, and the auxiliary plate does not hinder the seating operation or the standing operation. Then, by spreading the auxiliary plate after seating, the elbow mounting surface is widened and a sufficient elbow mounting area is obtained.

In the armrest according to the third aspect of the invention, the partition wall and the auxiliary plate sandwiching the partition wall form a flat armrest surface. In this case, even when the auxiliary plate is inverted in the width direction and folded to be used as a narrow width elbow, a flat elbow rest surface can be formed by the auxiliary plate and the partition wall.

[0010] In the armrest of the connecting chair according to the sixth aspect, the partition wall is formed separately from the elbow, and comprises a mounting portion for holding the elbow and a partition, and the mounting portion is detachable from the elbow. It can be attached and retrofitted. In this case, even in the case of an existing armrest device in which a partition wall is not provided on an elbow, a partition wall can be provided later.

Further, like the armrest according to the present invention, the partition wall is formed separately from the elbow, and the partition wall is attached to the elbow so as to be horizontally movable in the opposite directions at the front and rear of the elbow. Alternatively, the width of the left and right elbow resting surfaces of the partition wall may be made different between the front and rear of the elbow tree so that the position of the partition wall can be adjusted. In this case, the shape and area of the region where each occupant places his or her elbow can be changed according to the physique, posture, and the like of those who sit on both sides of the elbow. In addition, a person who sits next to each other can use one elbow tree at the same time without touching the arms and elbows by alternately hanging the elbows and arms back and forth.

Further, the partition wall does not need to always protrude from the elbow resting surface, and it is sufficient if the partition wall protrudes or is set as necessary at least when the armrest is used. For example, as in the case of the armrest according to the fourth aspect of the present invention, the partition wall may be formed separately from the elbow, and may be provided so as to be able to penetrate the elbow in the vertical direction and to protrude and retract on the elbow rest surface. Further, like the armrest of the invention according to claim 5, the partition wall is formed separately from the elbow,
The partition wall is connected to the front edge or the rear edge of the elbow tree or in the vicinity thereof in a reversible manner, and the partition wall can be placed on the elbow rest surface of the elbow tree by flipping the partition wall forward or backward. In these cases, when there is no need to share the elbow with the vacant seat or the next seat, the elbow resting surface should be flat and widely used by storing or reversing the partition wall and removing it from above the elbow. Can be.

Further, the shape of the partition wall is not limited to a linear plate, but may be curved. For example, as in the armrest according to the seventh aspect of the present invention, the partition wall may be curved, and the width of the left and right elbow rest surfaces of the partition wall may be different between the front and rear of the elbow. In this case, those who sit next to each other can use one elbow at the same time by alternately hanging the elbow or arm back and forth without touching the arm or elbow to each other.

The elbow rest surface of the elbow is usually flat, but may have irregularities in some cases. For example, in the armrest of the connecting chair according to the ninth aspect, the center of the elbow resting surface of the elbow tree protrudes. In this case, the arm part is placed and the elbow part rises, so that the elbow does not hurt even if the arm is put on for a long time.

According to a tenth aspect of the present invention, there is provided an armrest apparatus for a coupled chair in which a plurality of chair bodies are connected to each other in a left-right direction and an adjacent seat shares an elbow. And an auxiliary plate connected reversibly to the elbow. The elbow mounting area can be expanded by inverting the auxiliary plate. In this case, the width of the elbow is reduced by folding the elbow, so that the elbow does not obstruct the sitting operation or the standing operation. On the other hand, by expanding the folded elbow after seating, the elbow resting surface is widened, and a sufficient elbow rest area is ensured so that the arm or elbow does not touch.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail based on the best mode shown in the drawings.

FIG. 1 shows a first embodiment of an armrest of a connecting chair to which the present invention is applied. The connected chair is composed of a plurality of chair bodies 1 connected to the left and right, and an elbow 2 of the same armrest device between adjacent seats.
Is shared. The elbow 2 is provided with a partition wall 3 that partitions the upper surface 2a of the elbow rest on the left and right. In addition,
The elbow 2 is fixed to the upper surface of the leg 14 between the chair bodies 1.

The partition wall 3 is formed, for example, over substantially the entire length of the elbow 2 in the depth direction. This partition 3
When the occupants on both sides place their elbows on the elbow 2, the arms and elbows are formed so high that they do not directly touch. That is, the areas used by the occupants on both sides are separately secured in advance, and even if both of them are placed on the elbow 2 at the same time, the contact of the elbows and arms is prevented by the central partition wall 3. Of course, partition wall 3
The height must be at least enough to allow the user to notice the existence of the partition wall 3, and the height of the partition wall 3 must be formed so as to ensure that it does not come into contact with the arm or elbow of a person sitting next to the seat. And do not form the entire length at the same height.
For example, the height of the partition wall 3 on the front side of the seat may be reduced as shown by a virtual line and hatching with respect to the partition wall 3 of the elbow 2 in the middle of FIG. Furthermore, the partition wall 3 may be formed intermittently in the depth direction, may be provided partially, or may be formed partially high. For example, the partition wall 3 may be provided only at the portion of the backrest that is likely to come into contact with the arm or elbow of the person sitting on the next seat (the back side of the seat indicated by phantom lines and hatching in FIG. 1). In this embodiment, the partition wall 3 is integrally formed of the same material as the elbow 2 such as wood or synthetic resin.

According to the armrest for a connected chair constructed as described above, the partition wall 3 makes the left and right borders of the elbow rest surface 2a of the elbow 2 clear, and the areas to be used by the left and right occupants respectively. It becomes clear. Therefore, the seated person next to the arm rests his or her elbow or arm on each of the elbow resting surfaces 2a, 2a which are divided into right and left, so that the opponent can use it without hesitation and touch the arm or elbow of the neighbor. You don't have to feel uncomfortable and get a comfortable sitting.

In the present invention, a part of the elbow can be folded in the width direction so that the elbow rest surface can be expanded at the time of use. For example, as shown in FIG. 2 or FIG. 3, a part of the elbow may be foldable so that the size of the elbow resting surface is variable. The chair body 1 and the legs 14
1 is the same as that of FIG. 1, only the elbow 2 and the like will be illustrated and described below, and the redundant description of the chair body 1 and the like will be omitted.

The elbow 2 shown in FIG. 2 includes a substrate 4 having a partition wall 3 projecting vertically and a substrate 4 having a partition wall 3 sandwiched therebetween.
It is composed of auxiliary boards 6, 6 laid on top of each other and connected to the board 4 in a reversible manner in the width direction. Are provided so as to protrude. That is, a pair of auxiliary plates 6, 6 are foldably attached to both side surfaces of the substrate 4 by the hinges 5, 5. Here, partition wall 3
Are formed so as to protrude slightly when the auxiliary plates 6 and 6 are folded, or to protrude to a height that functions sufficiently as a partition wall even in this state. In this case, it can be used as it is in the same manner as the elbow 2 in FIG. Further, the partition wall 3 does not need to protrude beyond the auxiliary plates 6 and 6 when the auxiliary plates 6 and 6 are folded.
As shown in the figure, the partition wall 3 and the auxiliary plates 6 and 6 for sandwiching the partition wall 3
The height may form a flat elbow resting surface 2a.
The height of each auxiliary plate 6 in this case is set to be the same as the height of the partition wall 3. In addition, it is preferable that the corners of the auxiliary plates 6 and 6, which are both corners of the elbow 2 in the folded state, have roundness as shown in FIG.

According to the elbow structure constructed as described above, the elbow can be used as it is, but when the auxiliary plates 6 and 6 are turned over and deployed, the area of the elbow rest surface 2a is reduced. Is almost doubled, and the convenience of the elbow 2 is improved. Of course, there is a case where only one auxiliary plate 6 is deployed and used. Moreover, when the developed auxiliary plates 6 and 6 are folded, the width of the auxiliary plates 6 and 6 protruding in the width direction is reduced to almost half, and does not hinder the sitting operation and the standing operation.

Further, the partition wall 3 may be formed integrally with the elbow 2 as in the embodiment shown in FIGS. 1 to 3, but is not particularly limited thereto. As shown in FIGS. They may be formed separately and fixed by bonding, screwing, fitting, or the like, or may be movably connected by hinges, shafts, guides, or the like. Further, the partition wall 3 does not need to always protrude from the elbow rest surface 2a, but it is sufficient if the partition wall 3 protrudes or is set as necessary when using the armrest.

For example, as shown in FIGS. 4 and 5, the partition wall 3 is formed separately from the elbow 2 so that the partition 3 penetrates the elbow 2 in the vertical direction and is provided on the elbow rest surface 2a so as to be freely retractable. good. That is, a lock mechanism (not shown) for forming a slit 13 in the elbow 2 and for holding the partition wall 3 in a state of protruding from the slit 13 is provided. While being stored in the one leg 14, the elbow 2 may be pulled up from the slit 13 and fixed in position by the lock mechanism during use.
Reference numeral 15 denotes a depression for picking up the elbow 2 when the elbow 2 is raised.

As shown in FIG. 6, the partition wall 3 is formed separately from the elbow 2 and is connected to the front edge or the rear edge of the elbow 2 or in the vicinity thereof in a reversible manner.
The partition wall 3 can be placed on the elbow rest surface 2a of the elbow 2 by inverting the frontward or rearward. For example, a bracket 16 is provided at the rear end of the bottom surface of the elbow 2.
The bracket 16 is attached to the partition wall 3.
Arm 3a is rotatably connected. Therefore, by lifting the partition wall 3 backward, the partition wall 3
Can be removed. When the partition wall 3 is removed, the partition wall 3 hangs from the bottom surface of the elbow 2 and does not become an obstacle. When the partition wall 3 is lifted while rotating from this state, the partition wall 3 is set on the elbow 2 and partitions the upper surface thereof left and right.

In the case of these embodiments, when there is no need to share the elbow 2 with the adjacent seat or the next-seat seat, the partition wall 3 is stored or inverted and removed from the elbow 2 to remove the elbow. The surface 2a can be used flat and wide.

The partition wall 3 may be movable as in the embodiment shown in FIGS. The partition wall 3 of the elbow 2 in this embodiment is a plate formed separately from the elbow 2, and is attached to substantially the center of the elbow 2 so as to be rotatable in the horizontal direction by a shaft 7, and the front and rear of the elbow 2 By moving horizontally in the opposite direction, the width of the left and right elbow resting surfaces 2a, 2a of the partition wall 3 differs between the front and rear of the elbow 2. Note that a lock mechanism for fixing the position of the partition wall 3 may be provided, and after the position of the partition wall 3 is adjusted, the partition wall 3 may be fixed to the elbow 2.

In such a configuration, when the partition wall 3 is turned in the horizontal direction indicated by an arrow in the figure, the direction of the partition wall 3 is swung right and left to change its position, and the shape and area of the region where the elbow is placed Can be changed. The occupant can adjust the position of the partition wall 3 according to his or her physique and posture.

As shown in FIGS. 9 and 10, guide means, for example, a pair of guide slits 8, 8 are formed at the front and rear of the elbow 2, respectively, and a partition provided separately from the elbow 2 is provided. By providing and fitting a pair of sliders 9, 9 penetrating through the respective guide slits 8 at the front and rear ends of the wall 3, the front and rear sides of the elbow 2 can be horizontally moved in opposite directions so that the front and rear of the elbow 2 can be moved. Thus, the widths of the left and right elbow resting surfaces 2a, 2a of the partition wall 3 are made different. Also in this case, the shape and area of the region where each occupant places his or her elbow can be changed according to the physique, posture, and the like of the person sitting on the seats on both sides of the elbow tree.

In the above description, the partition wall 3 is formed straight in the front-rear direction of the elbow 2; however, the partition wall 3 does not necessarily need to be formed straight.
As shown in (2), the partition wall 3 may be formed in a curved shape when viewed from above.

The elbow rest surface of the elbow is usually flat, but may have irregularities depending on the case. For example, as shown in FIG. 12, the bulge 17 may be formed on the elbow 2 according to the shape of the arm of the seated person.

FIGS. 13 and 14 show another embodiment. In the armrest of this embodiment, a partition wall 3 is formed separately from the elbow 2 so that it can be retrofitted to the elbow 2. For example, the partition wall 3 is a plastic molded product 10 integrally molded by injection molding, extrusion molding, vacuum molding, compression molding, or the like, and includes the mounting portions 12 and 12 holding the elbow and the partition portion 3 serving as the partition wall. It is detachably attached by inserting the attachment portions 12 and 12 into the elbow 2. Also in the case of this embodiment, the partition wall 3 may be curved in a substantially S-shape, or a part of the elbow rest surfaces 2a, 2a, for example, may be bulged at the center.

In the case of this embodiment, even if the armrest of an existing connecting chair in which the partition wall 3 is not provided on the elbow 2,
Partition walls can be provided later. Further, since it is a plastic molded product, a known or new antibacterial treatment or the like can be easily performed. And because it can be manufactured at low cost,
It can be disposable, and it is easy to regenerate it. Therefore, it can be made hygienic and easy to manage for use in movie theaters and theaters used by an unspecified number of customers. In addition, since coloring and patterning can be easily performed at the time of injection molding, the design can be diversified. As shown by a two-dot chain line in FIG. 13, the elbow rests 11, 11 projecting in the width direction from the elbow 2 may be formed integrally with the partition wall 3.

The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the gist of the present invention. For example, in the above-described embodiment, the structure in which the partition wall 3 does not mainly touch the arm or elbow of the person sitting in the adjacent seat has been described. However, the present invention is not particularly limited to this, and the person sitting next to the arm only when using the armrest is used. The elbow resting area may be sufficiently large so that the arm or elbow does not touch. That is, as shown in FIG. 15 or 16, the elbow 2 is constituted only by the substrate 4 and the auxiliary plate 6 which is superposed thereon and connected to the substrate 4 so as to be reversible in the width direction. The elbow rest area can be expanded by inverting. More specifically, as shown in FIG. 15, a pair of auxiliary plates 6, 6 are foldably attached to both side surfaces of the substrate 4 by hinges 5, 5. Therefore, when the auxiliary plates 6 and 6 are inverted in the width direction and folded, the elbow 2 having the same width as the conventional one is formed, and when the auxiliary plates 6 and 6 are expanded in the width direction, the elbow rest surface is doubled. . As shown in FIG. 16, one auxiliary plate 6 having the same size as the substrate 4 may be attached to one side surface of the substrate 4 in a reversible manner by a hinge 5 so as to be foldable. In these cases, when the auxiliary plate 6 is folded, the width of the elbow 2 becomes narrower, and does not hinder the seating operation or the standing operation. On the other hand, by spreading the folded auxiliary plate 6 after seating, the elbow resting surface is widened, and a large enough elbow resting area can be secured so that the arm or elbow does not touch.

Further, the present invention has mainly been described with respect to the embodiment in which the partition wall 3 is attached to the elbow 2,
The present invention is not particularly limited to this, and the partition wall 3 may be attached to the backrest or the seat of the chair body 1. For example, as shown in FIG. 17, the frame 18 supporting the partition wall 3 is fixed to the side or back of the backrest of the chair body 1 with screws 19, and the partition wall 3 is placed on the elbow 2. Sometimes attached to. At this time,
The partition wall 3 may be formed integrally from the stage of manufacturing the chair, or may be attached to the existing chair body 1 by retrofitting. Further, the partition wall 3 is fixed to the frame 18, but may be swingably connected and supported as shown in FIG. 6 in some cases. Furthermore, the partition wall 3 in each of the above-described embodiments is disposed integrally or in close contact with the elbow 2, but is not particularly limited thereto, and a gap S is formed in the elbow 2 as shown in FIG. It may be installed so as to float above the elbow 2. In this case, the same effect as that of the embodiment of FIG. 1 can be obtained.

[0036]

As described above, in the armrest of the articulated chair to which the present invention is applied, since the partition wall which partitions the elbow rest surface on the upper surface of the elbow tree into right and left is provided, the area used by the left and right occupants in advance. Can be secured separately,
The contact between the elbow and the arm can be prevented. For this reason, the occupant does not need to take extra care, and even if the neighbors lack manners, they do not feel uncomfortable,
It will be comfortable and comfortable.

In the armrest according to the second aspect, since the elbow is foldable in the width direction and the elbow rest area is adjustable, the elbow rest can be expanded after seating to secure a large elbow rest area. The arms and arms can be placed easily, and the width of the elbows is reduced by folding the elbows, so that they do not become an obstacle when sitting or standing up. Therefore, it is possible to provide an elbow that can be comfortably shared with the next person without reducing the number of connecting chairs or increasing the width of the entire connecting chair.

Further, in the armrest according to the third aspect, even when the auxiliary plate is folded and used alone as a narrow elbow, the same usability as a conventional elbow can be obtained.

According to the fourth and fifth aspects of the present invention, when there is no need to share the elbow with the occupant or the adjacent seat, the partition wall is stored or turned over and removed from the elbow 2. Thus, the elbow rest surface can be used flat and wide, so that the elbow can be used alone without the partition wall being in the way.

In the armrest device according to the sixth aspect, a partition wall can be formed later on the armchair of the existing connecting chair.

According to the armrests of the seventh and eighth aspects, the width of the left and right elbow rest surfaces of the partition wall can be made different between the front and the rear of the elbow, so that the elbow or the arm can be placed in front of the elbow. A comfortable armrest position can be set, for example, for a person to put on, an elbow or an arm only on the back side, or when these people sit next to each other. Alternatively, a person sitting next to each other can alternately use the elbow or arm back and forth to use one elbow simultaneously without touching the arm or elbow to each other.

In the armrest according to the ninth aspect, the elbow portion rises when the arm is placed, so that the elbow does not hurt even if the arm is placed for a long time.

Further, according to the armrest according to the tenth aspect, since the elbow is foldable in the width direction and the elbow mounting area can be adjusted, the seated person can be seated without increasing the size of the connecting chair in the width direction. The space for the elbow can be expanded.
