Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a chair set consisting of a plurality of chairs that are used in conjunction with each other.

Conventional technology and its problems Many chairs of the same type are placed side by side in the lobbies of hotels and halls, but when a large number of chairs for one person are arranged, the arrangement is left to the will of the user and the arrangement becomes chaotic, and it is difficult to arrange chairs for multiple people. When using a chaise longue, the sitting direction is 1.
The disadvantage is that it is limited to. Furthermore, even when it comes to sofas used at home, it is convenient for conversation, etc., if the sofa can be used not only as an integrated chaise longue, but also by changing the orientation appropriately for each person sitting on it.

On the other hand, as a chair that has a structure that allows multiple items to be connected, there is a folding chair that can be connected sequentially in the width direction, but since the chairs are fixed in a straight line by connecting, each chair can be It is unsuitable when changing direction is desired.

The purpose of the present invention is to solve the problems of the prior art and to provide a chair that maintains a constant state of connection and allows the direction of each chair to be changed to make it convenient for conversation, etc.

Means for Solving the Problems The object of the present invention is to provide support chairs that can stand on their own and are spaced apart facing the same side, and the lower surfaces near the corners of the front ends of the seats of these support chairs that are closer to each other. a support rod whose ends are rotatably coupled around a vertical axis and extends between the support chairs; and a mounting member located between the support chairs with the underside of the seat supported on the support rod. This is achieved by a set of chairs characterized by comprising a chair.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an example of a chair set consisting of three chairs in which a mounting chair 2 is placed between two supporting chairs 1, 1. The support chair 1 has legs at four corners so as to be able to stand on its own, and has a seat part 10 and a backrest part 11 located on the same side and spaced apart from each other. The seat part 10 and the backrest part 11 can be the same as those of a normal chair. As shown in FIG. 3, the legs, except for the front leg 12 that is closer to the other support chair 1, are regular legs 13 with studs, and are screwed into mounting holes provided on the underside of the seat 10 for installation. It is being The length of the front leg 12 from the bottom of the leg to the upper end of the stud is the same as that of the leg 13, but the exposed portion of the stud is lengthened by the thickness of the support rod, which will be explained below, and is inserted through the through hole of the support rod. It is screwed into a mounting hole on the lower surface of the seat portion 10. The support rod 3 has vertical through-holes 30 at both ends, through which the bolts 120 of the legs 12 are passed, and the support rod 3 is attached to the support chair 1 so as to be rotatable about a vertical axis. The mounting chair 2 is constructed similarly to the supporting chair 1, with the following exceptions. The mounting chair 2 does not have front legs attached, but instead supports the lower front part of the seat by a support rod 3.
As shown in Fig. 2 (bottom view), a mounting piece 24 protrudes from the underside of the seat to connect with the support rod 3 and position the chair 2, and is fixed to the rod 3 with screws. There is. In this example,
The support chair 1 and the mounting chair 2 are designed to be compatible with each other. Therefore, each chair is provided with leg attachment holes 15, 25 and support rod attachment pieces 14, 24, respectively, on the underside of the seat. The support rod 3 has a shape in which the center part is bent and recessed toward the rear of the chair 2 from both ends so that it does not extend over the flange part of the leg attachment hole 25 and is difficult to see from the front of the chair. ing. Further, in this example, the backrest portion 21 of the chair 2 is configured as follows. That is, as shown in FIG. 4, the backrest part 21 includes a guide part 211 attached to the rear part of the chair so as to guide it in the vertical direction, and a guide part 211 that extends upward from the guide part 211 and moves up and down while being guided by the guide part. Ururu rod 212 and the rod 2
12 Backrest member 213 attached to the upper end part
and a spring device 214 that is installed between the guide portion and the rod and biases the rod upward so that the backrest member and the rod can descend against the spring force as the seater leans back. . Backrest member 2
14 is normally held in the raised position by spring force, and the void to allow lowering from the raised position is surrounded by a drapery 215.

Furthermore, in this example, a side table 4 appears between each chair. The side table is fixed to both sides of the bottom of the seat of the attached chair, and its planar shape is fan-shaped with the front legs 12 as the center of curvature. At the side edge of the bottom of the seat of the support chair 1, there is a support bar 5 for supporting the side table 4.
is provided.

Function: Therefore, in this set of chairs, by arranging the support chair 1 and the mounting chair 2 so that their sides are in contact with each other, a straight long chair is constructed, and from this position, the support chair 1 is connected to the support rod 3. By rotating around the connection with the support chair 1, the orientation of only the support chair 1 can be changed without changing the position of the mounting chair 2. This change in orientation strengthens the tendency for the occupants of both chairs to face each other, resulting in a convenient arrangement for conversation and the like. The positions of the three chairs can be changed freely no matter which chair is fixed. Also, in this example, the side table 4 is attached to the chair 2.
Since the support chair 1 and the mounting chair 2 are rotated and separated from each other, the side table 4 appears in the gap between the two chairs. Since the side table 4 is fan-shaped with the front legs 12 as the center of curvature, the chair can be rotated smoothly without being hindered by the table 4.

Further, in this example, since the backrest portion of the attached chair 2 is provided with a backrest member 213 that can be moved up and down under the force of a spring, the seater can take a normal sitting posture, or by leaning back, the backrest member 213 can move up and down under spring force. It is also possible to lower the backrest member 213 against the force and take a posture in which the user's back or hips are supported at a low position and arch backward. (See Figure 5).

In the above example, a set of chairs is constructed of three chairs, but a support rod 3 is installed between any two or more support chairs, and a chair is supported on the support rod. In this way, the number of chairs can be increased as needed to form a set of chairs. If the support of the mounting chair by the support rod is sufficiently strong, the rear legs of the mounting chair can also be omitted. In this case, a support rod may also be installed between the rear legs of both support chairs to ensure the support. It is of course possible to attach the side table 4 by providing the fixed end on the support chair 1 and providing the receiving crosspiece 5 on the mounting chair. In the above example, a chair with a backrest that can be moved up and down was used as a mounting chair, but each chair is designed so that the legs, support rods, and side table support bars can be freely changed. A chair provided with a backrest can also be used as a support chair, and the arrangement of the corner chair can be appropriately determined, especially taking into consideration the space for the seater to lean back. In addition, various features other than the movable backrest can be added to each chair, and a set of chairs can be arranged to suit preferences and needs based on the compatibility between the chairs. The support rods can take various forms other than those shown in the examples above. Support rod 3a shown in FIG.
has vertical mounting holes 30a at both ends, and is attached to the front legs of the support chair in the same way as in the previous example, and has coupling holes 31 to the mounting pieces on the underside of the chair seat.
This is connected by a screw passing through a, but it differs from the previous example in that it includes a hinge part 32a and a telescopic fitting part as shown in the figure. Hinge part 32
A is provided on both ends of the rod from the pair of coupling holes 31a, and each arm 33a on the distal end side thereof is rotatable about a vertical axis as shown by arrow A with respect to the central portion 34a. The arm 33a is divided into a base end 35a and a distal end 36a, which are telescopically fitted in a telescopic manner. The distal end portion 36a receives a spring force from a built-in tension spring (not shown) in the direction of shortening the length of the arm portion, and can be extended from the base end portion 35a in the direction of arrow B. When this support rod 3a is used, even if the support chair and the mounting chair rotate in directions away from each other and touch adjacent front end corners, the arm portion 33
By extending a, the chair can continue to rotate more smoothly. After such rotation, when both chairs are rotated in a direction toward each other, the extended arm portions 33a are contracted by the spring force, and a linear arrangement with the side portions of both chairs in contact with each other can be easily obtained. Further, since the hinge portion 32a is provided, together with the above-mentioned expansion and contraction of the arm, it is possible to rotate both the supporting chair and the mounting chair with their front end corners aligned.

Effects of the Invention As is clear from the above explanation, according to the present invention, it is possible to provide a set of chairs that has the following effects. That is, since the attached chair is supported on the support rod installed between the support chairs on both sides thereof, it can have a simple structure in which one or both of the front legs and the rear legs are omitted depending on the supporting position. Since the support chair is connected near the front end corner to the support rod so as to be rotatable around a vertical axis, the attached chair and the support chairs on both sides can maintain the state of connection of the front end corner with the adjacent chair, and The orientation of each can be changed as desired.
