DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair which can be used by being laterally connected to each other.

[0002]

2. Description of the Related Art As one of the types of chairs, there is one that has a structure in which the chairs are laterally connected to each other so as to arrange them in a hall or the like. In such a type of chair, especially when it is a chair with an armrest, the lateral connection makes the armrest bulky, and the arrangement pitch is large, and the arrangement efficiency is lower than the chair without the armrest. .

Therefore, for example, as shown in FIGS. 10 and 11, a chair B disclosed in Japanese Patent Publication No. 57-35967 discloses an armrest support in which an armrest 102 stands up from the chair body 101 toward the front and the outside. 106 and an armrest main body 107 which has a front end portion integrally connected to the upper end portion of the armrest support 106 and extends rearward from that position.
02, the upper end of the armrest support 106 and the armrest main body 1
At the boundary portion X with the front end of 07, the chairs B can be combined with each other by crossing and colliding with each other and engaging the insides 107a of the armrest main bodies 107 with each other.

[0004]

However, although such a connecting structure is effective in reducing the arrangement pitch, the boundary portion X for crossing the armrests 102 with each other is seated by a person. When the elbow is placed on the main body 102, it is located at a position where the hand is just put. Therefore, when the chair B is displaced in the front-rear direction, there is a risk that a finger may be caught between the front and rear armrests 102 at the boundary portion X,
It is a danger. Also, the armrests 10 of the chairs B adjacent to each other
2 is required to be shared by this boundary portion X, which is inconvenient. Further, since the vicinity of the boundary portion X is twisted outward so that they can be easily crossed with each other, as shown in FIG. 10, the armrest main body 107 is detached outward from the extension line of the elbow when the hand is put on. Yuki, the usability is impaired. Furthermore, as is clear from FIG. 11, since the front end portion of one armrest body 107 and the front end portion of the other armrest body 107 have different front and rear positions, the amount of forward protrusion of the left and right armrests 102 is reduced. There is also the drawback that it will be different and that it will not look good from the side.

An object of the present invention is to solve these problems at once.

[0006]

In order to achieve the above object, the present invention employs the following configuration.

That is, the chair of the present invention is a chair in which an armrest is attached to a chair body, and the armrest stands upright and outward from the chair body, and the armrest support. It consists of an armrest body that is integrally connected to the front end at the upper end and extends rearward from that position, and at the connecting position of the chairs, the armrest support of adjacent armrests is an intermediate part or a proximal end part. in abut back and forth by the intersection, and the armrest main body with each other Rutotomoni butt each other of the inner surface on the left and right, the armrest support bodies of each other
Butt the outer surfaces of the base ends to the left and right, and position the chairs laterally.
It is characterized by making arrangements.

In order to make the appearance of the chair look good, it is desirable that the adjacent armrest main bodies have their front end portions supported at the same front and rear positions. As a specific embodiment for that purpose, the adjacent armrest supports are fixedly fixed at their base end portions at different front and rear positions, and are erected forward at different angles from that position so that their upper end portions are at substantially the same front and rear positions. The thing arrange | positioned is mentioned.

In order to make the armrests safe and convenient when the chairs are connected to each other, it is desirable that a lateral gap be formed between the front end portions of the adjacent armrest bodies.

[0010] When connecting the chair to each other, wherein in order also to prevent longitudinal displacement of the chair in the abutment portion, the outer surface facing the position of the base end of the adjacent armrest support, the armrest support before and after each other It is desirable to form an engaging portion that gives resistance to the separating operation in the direction.

[0011]

With the chair having such a structure, when the armrests are in a sitting posture and the elbows are out of reach of each other when the chairs are seated, that is, in the middle portion or the proximal end portion of the armrest support, when connected. Crossing each other, and a part from the upper end of the armrest support to the armrest main body is opened to avoid mutual collision. Therefore, even if the chair shifts back and forth, the risk of pinching a finger can be eliminated. Moreover, with such a structure, each person sitting on the adjacent chair can completely use the armrest main body of the other party including the upper end portion of the armrest support, so that the convenience is also good. Become. Also, the outer surface of the base of the adjacent armrest support
The chairs are connected to each other because they are abutted against each other.
In this case, it is possible to prevent lateral rattling more reliably.
You. In particular, in the case where a gap is formed between the front ends of the armrest main body, the collision between the armrests is more reliably avoided, the safety is further improved, and a sufficient space for the armrest is secured. Will be done. further,
In the configuration of the present invention, it is not necessary to twist the vicinity of the boundary between the upper end of the armrest support and the front end of the armrest main body for crossing, and since it can be positioned on the extension line of the elbow, it is natural when used. By extending the hand in this state, the hand can be placed near the boundary, and the usability is further improved. Furthermore, in such a configuration, the front end portions of the adjacent armrest main bodies can be arranged at the same front and rear positions only by changing the standing angles of the armrest main bodies, so that the front protrusion amounts of the left and right armrests are the same. It is possible to improve the appearance of the chair without difficulty.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 to 3, the chair A of this embodiment has an armrest 2 detachably attached to the left and right edges of the chair body 1.
It consists of a fixed structure. In the following description, when it is necessary to particularly refer to the left-right relationship in the description of each part, the corresponding reference numeral is attached with the suffix (R) or (L).

The chair body 1 is provided with a leg 3 that spreads downward, a seat 4 supported by the left and right legs 3, and a backrest 5 integrally connected to the seat 4. The leg 3

The armrest 2 is made by integrally molding an armrest support 6 and an armrest body 7 with resin. Although the boundary portion between the armrest support 6 and the armrest main body 7 is not always clear, in the present embodiment, a portion that rises in a substantially straight line diagonally forward is included in the armrest support 6 side while curving. Consider the upper part of the armrest main body 7 side from the part starting to extend rearward and upward.

The armrest support 6 stands up from a block-shaped base end mounting portion 61. The base end mounting portion 61 is thick, and the inner surface of the base end mounting portion 61 is, as shown in FIG.
And a columnar protrusion 61c that fits into the armrest mounting hole 33c and a bolt insertion hole 61d that is continuous with the bolt insertion hole 33d. Then, as shown in FIGS. 2 and 3, the entire armrest support body 6 is erected from the base end attachment portion 61 while being simultaneously inclined forward and outward. The left and right armrest supports 6
Although (L) and 6 (R) have the same base end mounting portion 61, as is clear from FIGS. ) Stands up from a position forward of the left armrest support 6 (L). The former has a steeper rising angle than the latter, and conversely, the latter has a smaller standing angle than the former but is elongated and its upper end portions 62a are at the same height position and at the same front and rear. It is located at the position.

The armrest main body 7 is supported in a cantilever manner on the upper end of the armrest support 6, and has a streamlined vertical portion 71 extending from the front end portion 7a thereof to the upper rear portion while smoothly curving. The vertical arm 71 has an armrest 72 integrally and substantially horizontally extending inward from the upper edge of the vertical arm 71.

The chairs of this embodiment having the above-mentioned structure are connected to each other in the state shown in FIGS. 5 and 6 by arranging them closely adjacent to each other in the lateral direction. That is, of the adjacent chairs A (L) and A (R), the armrest support 6 on the right side of the chair A (L) arranged on the left side.
With respect to (R), the armrest support 6 (L) on the left side of the chair A (R) arranged on the right side is erected on the back side. As described above, since the armrest supports 6 (R) and 6 (L) differ in the standing base end position and the standing angle, they intersect at the intermediate portion and abut in the front-back direction. At this time, since both armrest supports 6 (R) and 6 (L) extend in the direction of separating after crossing, the horizontal portion 72 (R) of the armrest main body 7 (R) connected to the upper end thereof. And armrest body 7
The armrests 72 (L) of (L) are arranged at positions left and right interchanged, and their inner surfaces 72a (R), 72a.
Let (L) abut each other. Furthermore, chair A on the left side

The outer surface abutment portion of 1 (R) is positioned, and the positioning in the front-rear direction is performed at the front and rear abutment portions of the armrest supports 6 (L) and 6 (R).

The base end mounting portions 61 (L), 61
In (R), as shown in FIG. 7, ridges 61e are provided at positions where the phases are shifted, and these ridges 61e form the engaging portion 9 of the present invention. And the armrest support 6
When (L) and 6 (R) move away from each other in the direction of the arrow in the figure, the resistance generated when the raised portions 61e try to get over each other prevents the displacement due to the move-away operation. There is.

In the chair A having such a structure, the armrest 2 is not bulky in the lateral direction, so that the arrangement pitch of the chairs A when connected in the lateral direction can be effectively reduced, and the chair A is used in a hall or the like. In the case of doing, it is possible to reasonably increase the capacity of personnel. Moreover, when the elbows are placed on the armrests 2 in the sitting posture, the armrests 2 are out of reach of each other,
That is, the armrest support 6 is crossed at an intermediate portion thereof, and a region from the upper end of the armrest support 6 to the front end 7a of the armrest main body 7 is opened, so that mutual abutment at this region is avoided. Therefore, even if the chair A is displaced back and forth, the risk of pinching a finger is eliminated, and safety can be reliably improved. Moreover, with such a structure, since each person sitting on the adjacent chair A can exclusively use the armrest main body 7 of the other party, the hands of the neighbors do not interfere with each other and the usability is good. It becomes something. Particularly, in this embodiment, the armrest main body 7 is provided between the front end portion 7a as shown in FIGS.
Since the gap S as shown in FIG. 2 is formed, the collision between the armrests 2 is more surely avoided, the safety is further improved, and at the same time, the use space of the armrests 2 is sufficiently secured. Will be things. Furthermore, in the present embodiment, it is not necessary to twist the vicinity of the boundary between the upper end of the armrest support 6 and the front end 7a of the armrest main body 7 for crossing, and it can be positioned on the extension line of the elbow. If you reach out in a natural state, you can reach near the boundary,
The usability can be further improved. Furthermore, in this embodiment, the front end portion 7 of the adjacent armrest body 7 is
Since a is arranged at the same front and rear position, the amount of forward projection of the left and right armrests 2 becomes the same, and the appearance of the chair A can be reasonably improved both when used alone and when connected. .

In addition to the effects as described above, the chair A of this embodiment utilizes the fact that the armrest support 6 stands up toward the outside, and as shown in FIG. 8 and FIG. Also, since the rear pillars 32 on the rear side are vertically stacked so that they can be stacked, a compact storage mode is possible and the usability when applied to a hall or the like can be further improved.

The present invention is not limited only to the above-described embodiment. For example, in the above-described embodiment, the engaging portion for preventing the chair from moving backward and forward is the ridge portion having different phases provided on the outer surface of the base end portion of the armrest support, but the recesses and the recesses that fit each other at the same phase position are provided. You may comprise a convex part. Further, although the armrests are crossed at the intermediate portion of the armrest support in the above embodiment, they may be crossed at the proximal end portion. In addition, the specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0023]

As described above in detail, the present invention provides a chair which is laterally connected with the armrests crossing each other.
The crossover is performed at an intermediate portion of the armrest support or a portion near the base end. Therefore, it is possible to eliminate the risk of finger stuffing when the chair is displaced back and forth, and it is possible to dramatically improve safety. Furthermore, next door
The outer surfaces of the base ends of the armrest supports that are in contact with each other
Therefore, when connecting the chairs to each other,
Rattling can be prevented more reliably. Further, assuming such a configuration, the region from the front end of the armrest main body to the vicinity of the upper end of the armrest support can be formed into a relatively free shape, so that the shape can be easily hung,
By forming a gap between the front ends of the adjacent armrests, it is possible to effectively improve the usability of the armrests when used alone or when connected. Of course, it becomes easy to improve the appearance of the chair by aligning the front ends of the armrest bodies.
