Mode for Carrying Out the Invention

[0014] Hereinafter, a bench according to an embodiment of the present invention will be described with reference to the drawings. Note that the following embodiments are examples of the present invention, and the present invention is not limited to the following embodiments.

[0015] Hereinafter, with reference to FIG. 1, the configuration of the usage state of the bench 1 will be described.

[0016] As shown in Figure 1, the bench 1 comprises a pair of left and right legs 2 and 3, a seat 4, a backrest 5, and a holding means for holding the bench 1 in a folded state. In this embodiment, the dimensions of each part are set such that the length of the seat 4 in the left-right direction is approximately 100 cm, the length in the front-back direction is approximately 60 cm, and the height of the bench 1 in use is approximately 90 cm, but the dimensions of the bench 1 are not limited to these.

[0017] Leg section 2 has a front leg 21 and a hind leg 22. Leg section 3 also has a front leg 31 and a hind leg 32. Furthermore, leg section 2 has a lower frame 23 and an upper frame 24 extending from the front leg 21 towards the rear leg 22. Leg section 3 has a lower frame 33 and an upper frame 34 extending from the front leg 31 towards the rear leg 32.

[0018] In the illustrated example, the front leg 21 is joined to the lower frame 23 and upper frame 24, which extend in the direction of the rear leg 22. Similarly, the front leg 31 is joined to the lower frame 33 and upper frame 34, which extend in the direction of the rear leg 32. Adhesives, screws, and the like are used for these joining methods. The upper frames 24 and 34 are positioned higher than the surface of the seat 4 when in use, so that they can be used as armrests. According to the present invention, when the bench 1 is folded, the seat portion 4 can be held down by the legs 2 and 3, preventing the seat portion 4 from opening.

[0019] The hind leg 22 consists of a leg portion 22a and a support portion 22b. Similarly, the hind leg 32 consists of a leg portion 32a and a support portion 32b.

[0020] The lower frame 23 and the upper frame 24 are joined to the intermediate frame 25. The lower frame 33 and the upper frame 34 are joined to the intermediate frame 35. The leg portion 22a of the rear leg 22 and the intermediate frame 25 are rotatably connected to the seat portion 4 by a hinge. The leg portion 32a of the rear leg 32 and the intermediate frame 35 are rotatably connected to the seat portion 4 by a hinge.

[0021] Furthermore, the front leg 21 has a seat support member 26 that supports the seat portion 4 when the bench 1 is in use. Similarly, the front leg 31 has a seat support member 36 that supports the seat portion 4 when the bench 1 is in use. The seat support members 26 and 36 are attached to the front legs 21 and 31, respectively, so that they face each other when the bench 1 is in use. In addition, the seat support members 26 and 36 are provided with notched grooves (recesses).

[0022] The lower frames 23 and 33 are fixed to each end of the connecting member 6 by lap joints. The connecting member 6 also has a notched groove (recess) in the center. According to the present invention, when the bench 1 is folded, the seat support members 26 and 36 are adjacent to each other, and the notched grooves of the seat support members 26 and 36 and the notched groove of the connecting member 6 can be fitted together, thereby maintaining the folded state of the bench 1. In other words, the seat support members 26 and 36 and the connecting member 6 function as holding means to maintain the folded state of the bench 1.

[0023] The seat portion 4 consists of a rear seat portion 41 and a front seat portion 42. The rear seat portion 41 and the rear legs 22 and 32 are rotatably connected to the backrest portion 5. Hinges, rotating pins, etc., are used for the connection, and the connection is fixed when the bench 1 is in use. In addition, when the bench 1 is in use, the front seat portion 42 and the seat support members 26 and 36 are joined by a locking mechanism.

[0024] The backrest 5 consists of support columns 22b and 32b extending above the rear legs 22 and 32, and a back reinforcement section 51. Both ends of the back reinforcement section 51 are fixed to the support columns 22b and 32b, respectively. In the folded state, the rear legs 22 are curved from the leg portion 22a to the support column portion 22b so that the seat 4 folds approximately parallel to the backrest 5 while adjacent to it. Similarly, in the folded state, the rear legs 32 are curved from the leg portion 32a to the support column portion 32b so that the seat 4 folds approximately parallel to the backrest 5 while adjacent to it.

[0025] Next, we will explain the procedure for folding bench 1 using Figures 2 through 8.

[0026] First, as shown in Figure 2, remove the connecting member 6 from the lower frames 23 and 33.

[0027] Next, as shown in Figures 3 and 4, the locks between the seat support members 26 and 36 and the seat portion 4 are released, and the seat portion 4 is folded toward the backrest portion 5. At this time, the seat portion 4 is folded approximately parallel to the backrest portion 5 while remaining adjacent to it.

[0028] Then, as shown in Figures 5 and 6, the left and right legs 2 and 3 are folded toward the seat 4.

[0029] Finally, as shown in Figures 7 and 8, the notched grooves provided in the seat support members 26 and 36 are fitted together with the notched groove provided in the center of the connecting member 6. Furthermore, the rear leg protrusions 27 and 37 provided on the backs of the rear legs 22 and 32 are fitted together with the notched grooves provided at both ends of the connecting member 6. In other words, the rear leg protrusions 27 and 37 and the connecting member 6 also function as holding means to maintain the folded state of the bench 1.

[0030] Although one embodiment of the present invention has been described with specific examples, the present invention is not limited to the above-described embodiment, and modifications may be made as appropriate within the scope of the spirit of the present invention.

[0031] For example, the lower frames 23 and 33 and both ends of the connecting member 6 only need to be able to fit together, and may be a concave-concave fit. Similarly, the seat support members 26 and 36 and the connecting member 6 only need to be able to fit together, and may have a notched groove on either side.

[0032] In this embodiment, the back reinforcement section 51 is fence-shaped, but it may also be plate-shaped. Furthermore, while wood is preferred as the structural material for the bench 1 in terms of weight reduction, various materials such as synthetic resin or lightweight metals like aluminum alloy can be used individually or in combination depending on the application.

[0033] According to the present invention, the bench is securely held in a folded state, and the components do not unexpectedly open. Furthermore, the connecting members that were unnecessary in the folded state can be effectively utilized. [Industrial applicability]

[0034] This invention can be used in the development of folding benches. [Explanation of symbols]
