DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height-adjustable chair that can be stored on a wall.

[0002]

2. Description of the Related Art Chairs for rest are arranged at various places in public facilities and event venues where many people gather. Normal chairs can be used under conditions where a large space can be secured, but if space is not large enough compared to the group size, use chairs fixed to the wall or floor in addition to auxiliary chairs In some cases. However, fixed chairs hinder traffic in narrow passages and the like. Therefore, some chairs have a seat that can be folded and the seat is rotated along the wall surface so as not to protrude toward the space when not in use.

[0003]

However, even with a foldable chair, when not in use, the seat surface is stuck to the wall surface and the appearance is impaired. In addition, since it protrudes from the wall surface by the thickness of the seat surface, a pedestrian may be caught on the seat surface, possibly leading to an unexpected accident. Furthermore, the height of the seat cannot be raised or lowered in many cases, and it cannot be said that the seat is comfortable. The present invention has been devised to solve such a problem, and it is an object of the present invention to provide a chair which is completely stored on a wall so as to have no irregularities when not in use, and which can be adjusted in height. I do.

[0004]

SUMMARY OF THE INVENTION The retractable chair of the present invention comprises:
In order to achieve the object, a rack plate fixed to the back wall of the accommodation space formed on the wall surface, a rack is formed in a vertical direction, and a guide groove is formed in the vicinity of both sides in the left-right direction, and a bend fitted into the guide groove Parts are formed on both sides on the back side, a pair of bearings are provided on the front side, a slide plate with a square window opened below, and a seat surface support rotatably connected to the slide plate by pins supported at both ends by the bearings And a rack that engages with the rack of the rack plate through the square window of the slide plate on the end surface of the seat support plate protruding from the seat surface. It is preferable that the gap formed between the lower end of the seating surface in the housed state and the lower edge of the accommodation space be closed by a blind plate pivotally attached to the lower front edge of the accommodation space so as to be able to undulate. As the rack plate, the slide plate and the seating surface support plate, those formed from an extruded aluminum material are used. An aluminum decorative plate can be attached to the bottom surface of the seat so as to form the same plane as the wall surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a retractable chair according to the present invention, as shown in FIG. 1, a seating surface 10 protrudes orthogonally from a wall A in a use state (a), and a bottom plate 11 of the seating surface 10 in a non-use state. Are accommodated in an accommodation space B provided in the wall surface A so as to form the same plane as the wall surface A (b). The seat surface 10 is a seat surface support plate 1.
2 is embedded in a cushion material 13, and the cushion material 13 is wrapped by a bottom plate 11 and a surface material 14 (FIG. 2).
The bottom plate 11 is preferably provided so as to form the same plane as the wall surface A when the seat surface 10 is pushed into the accommodation space B. Further, if an aluminum decorative plate is used for the bottom plate 11 or the same cloth or the like as the wall surface A is attached, the design of the wall surface A in the stored state is improved. In addition, if the cue concave portion 16 is provided at an appropriate position, the undulating operation of the seat surface 10 becomes easy.

The seat support plate 12 is fixed at a predetermined position by bolts 15 inserted from the bottom plate 11, a pin hole 12a is formed at a portion protruding from the seat surface 10 toward the wall A, and a rack 12b is formed at the protruding end surface. Are formed (FIG. 3). The pin holes 12a, the racks 12b, and the like can be formed at the same time when the extruded aluminum material used for the seat surface support plate 12 is manufactured. Pins 22 whose both ends are supported by bearings 21 and 21 provided on the slide plate 20 are inserted into the pin holes 12a (FIG. 4). Blind holes or through holes into which the ends of the pins 22 are inserted are formed in the bearings 21 and 21. In the bearings 21 and 21 provided with the through holes, the pins 22 are prevented from falling off by using appropriate pin clips. The slide plate 20 is made of an extruded aluminum material, and has a rectangular cross-sectional shape with an open back as shown in FIG.
The bent portions 24, 24 face the rear opening 23 from both sides, and a gap 27 is provided between the bent portions 24, 24 and the front portion 25.
Is provided. In addition, below the slide plate 20,
A square window 26 into which the rack 12b of the seat support plate 12 enters is formed (FIGS. 3 and 8).

[0007] The slide plate 20 can be moved up and down.
0 is attached. As shown in FIG. 5, the rack plate 30 has a rack 31 formed at the center in the front surface in the vertical direction. On both sides of the rack 31, fitting projections 32, 32 that fit into the gaps 27 of the slide plate 20 are formed.
Rear portions 33, 33 are provided with a slight gap from 2, 32. Fitting protrusions 32, 32 and rear portions 33, 33
Are formed as guide grooves 37 into which the bent portions 24 of the slide plate 20 are inserted. This rack plate 30
Is formed by cutting or extruding an extruded aluminum material having a predetermined shape, and then machining or press-forming the rack 31. Here, in order to facilitate the processing of the rack 31, it is preferable to form the grooves 34 on both sides of the rack 31. Further, after securing the strength of the portion where the rack 31 is formed, it is preferable to provide a concave portion 35 on the back side to reduce the weight of the rack plate 30. The rear portions 33, 33 are formed with holes through which bolts 36, 36,... For fixing the rack plate 30 to the back wall C of the accommodation space B (FIG. 1) provided on the wall surface A are inserted.

On the wall A on which the chair can be stored,
An accommodation space B corresponding to the size of the chair is formed. A blind plate 40 is rotatably attached to the lower front edge of the accommodation space B. When the chair is not in use, the blindfold plate 40 is used for the seat surface 10.
One side edge is rotatably pivotally connected to a lower front edge of the accommodation space B by a hinge 41 so as to close a gap formed between the accommodation space B and the storage space B (FIG. 1B). Providing the cue recess 42 substantially at the center of the blind plate 40 facilitates the opening and closing operation of the blind plate 40. Further, stuck aluminum veneer D on the side wall C ₁ of the accommodating space B, it is preferable to improve the design. When installing in the accommodation space B, first, the fitting projection 32 of the rack plate 30 is fitted into the gap 27 of the slide plate 20, and the slide plate 20 is slidably combined with the rack plate 30 (FIG. 6). The rack plate 30 on which the slide plate 20 is mounted is fixed to the back wall C of the accommodation space B with bolts 36, 36,... (FIG. 7). Next, the seat 10
The pin holes 12a of the seating surface support plate 12 integrated with the pin holes 12a are matched with the pin holes of the bearings 21 and 21, and both ends of the pin 22 inserted into the pin holes 12a are supported by the bearings 21 and 21 (FIG. 8).

In a state where the seating surface 10 is laid down and protruded from the wall surface A, as shown in FIG.
b faces the rack plate 30 from the square window 26 of the slide plate 20, and the rack 31 of the rack plate 30 and the rack 12b mesh with each other. Thereby, the seating surface 10 is fixed at a predetermined height from the floor surface. When changing the height of the seating surface 10, the seating surface 10 is rotated slightly upward from the state of FIGS.
Is disengaged from the rack 12b. When the engagement is released, the seating surface 10 can move up and down along the guide groove 37 of the rack plate 30 together with the slide plate 20, so that the seating surface 10 is moved to a required height. Then, the seat 10 is rotated downward, and the rack 12b of the seat support plate 12 is engaged with the rack 31 of the rack plate 30 again. This allows
The bearing surface 10 is fixed at the position where the height has been changed.

When the seat 10 is stored when not in use,
Similarly, the seat 10 is rotated upward and pushed into the accommodation space B. At this time, the side of the seating surface 10 and the side wall C of the accommodation space B
_If the concave / convex portions for engagement are provided in ₁ , the seating surface 10 pushed into the housing space B is stabilized in the housed state. Then, when the gap formed between the seating surface 10 in the housed state and the lower surface of the housing space B is closed by the blind plate 40, it becomes flush with the wall surface A (FIG. 1b). Therefore, there is no protrusion that hinders the movement of the person, and the space can be effectively used, and the space itself is orderly.

[0011]

As described above, the retractable chair of the present invention can be accommodated in the accommodation space provided on the wall surface, and the height can be adjusted. Therefore, it can be used at a height suitable for the user, and when not in use, is stored in the housing space without protruding from the wall surface, and does not hinder movement or obstructive movement.
