Abstract

(57) [Summary] [PROBLEMS] To facilitate storage of a chair when not in use, and to enable attachment of a chair with a wall even if the wall has insufficient strength. SOLUTION: A frame fixed to a wall surface with one wood screw, and a rear end is pivotally attached to a lower end of a storage space of the frame via a hinge and is lowered when used so that a front end has a posture of about 1 degree elevation. A large stay in which the upper end is pivotally connected to the lower surface near the front end of the seat plate via a hinge, and the lower end is in contact with the floor surface in use at a position receded from the perpendicular by about 5 degrees in use. The front end is pivotally connected to the lower end of the large stay via a joint shaft, and the rear end is pivotally connected to a position near the lower end of the frame via a hinge. In use, the front end abuts on the floor surface and the rear end is an elevation angle. Equipped with a small stay that is held at a posture of about 2 degrees.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention is a chair with a wall that can be mounted with wood screws on the wall and can be folded. Regarding

[0002]

[Prior art]

  Conventionally, as a foldable chair with a wall that has been proposed for the elderly, JP 2001 -245751 and Japanese Patent Laid-Open No. 2000-41780 are known. They are When not in use, it is composed of a seat plate and a stay that supports the seat plate from diagonally below. Lift the seat and stays and store them on the wall. It is constructed so that B can be pulled out from the wall.

[0003]

[Problems to be solved by the device]

  However, these conventional walled chairs are subject to vertical loading on the seat when in use. Since it is directly applied to the wall surface through the seat plate and stay, it has the strength to withstand it. It had the drawback that it could only be attached to the wall. Also, the strength to withstand it Even a wall provided with a crease sometimes caused squeaking during use.

[0004]

[Means for Solving the Problems]

  Therefore, in order to solve the above-mentioned problems, in the device of claim 1, the lower end is brought into contact with the floor surface. And a frame that has a storage space at the top and is fixed to the wall surface with wood screws, The end is pivotally attached to the lower end of the storage space of the frame via a hinge and when not in use Is lifted and stored in the storage space inside the frame, and is pulled down when used. And a seat plate whose front end is held at an angle of elevation of about 1 degree and an upper end is below the seat plate tip end. It is pivotally attached to the surface via a hinge and is pulled up following the seat plate when not in use. Is held parallel to the seat plate, and the bottom end is retracted about 5 degrees from the vertical line when in use. And the front end of the large stay is pivotally attached to the lower end of the large stay via a joint shaft. Also, when the rear end is pivotally attached to the position near the lower end of the frame via a hinge and when not in use Is pulled up following the large stay and is held almost parallel to the frame. Is a small stay in which the front end is in contact with the floor surface and the rear end is held in a posture with an elevation angle of about 2 degrees. It is characterized by having.

[0005]   According to a second aspect of the present invention, in the first aspect of the present invention, between the frame and the large stay. A latch mechanism is provided to keep the large stay pulled up when not in use by connecting it to the frame. When not in use, a protrusion is provided on the upper surface of the small stay near the front end. The large stay and the small stay are set so that the protrusions come into contact with the frame when the stay is pulled up to the The feature is that the connection point of does not exceed the speculation point.

[0006]

[Embodiment of device]

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a chair with a wall according to the present invention. 2 is a right side view of FIG. 1, and FIG. 3 is a plan view of FIG. Well Further, FIG. 4 is a perspective view of a used state, and FIG. 5 is a perspective view of a folded state when not in use. It In these figures, 1 is a plate-like frame, and a storage space 11 is formed at the top. And is fixed to the wall 3 with a wood screw 2 on top of the frame 1. Seat plate 4 The rear end of the frame 1 is pivotally attached to the crossbar 12 of the frame 1 by a hinge 5. Then the seat At a position near the front end of the lower surface of the plate 4, the upper end of the plate-shaped large stay 6 is attached to the seat plate 4 by the hinge 7. It is pivotally attached. Further, the lower end of the large stay 6 is the same as the front end of the small stay 8 which is also plate-shaped. And the rear end of the small stay 8 by the hinge 21 of the frame 1. It is pivotally attached near the bottom edge.

[0007]   When the chair is used, the seat plate 4 is pulled down so that the front end of the seat plate 4 is elevated with respect to the rear end. It is held in an upward posture of about 1 degree. Also, the lower end of the large stay 6 contacts the floor surface 22. While being in contact with each other, the lower end is held while being inclined rearward about 5 degrees from the perpendicular. In addition, small The stay 8 has its front end in contact with the floor surface 22 and its rear end held in a posture of an elevation angle of about 2 degrees.   With this structure, when the chair is not used, the seat plate 4 has the hinge 5 as the axis. It is housed in the housing space 11 of the frame 1 by rotating upward. simultaneous Then, the large stay 6 is pulled up together with the seat plate 4, and Held in parallel. Similarly, the small stay 8 also rotates upward with the hinge 21 as an axis, It is held parallel to the frame 1.

[0008]   Furthermore, the present invention is designed to facilitate the storage of the chair when it is not in use, and 12, and latch mechanisms 23 and 24 are provided at positions near the lower end inside the large stay 6, When the chair is stored, the latch mechanism 24 of the large stay 6 is replaced by the latch mechanism 23 of the crossbar 12. The seat plate 4 and the large stay 6 are not retracted by their own weight in conformity with the above. I tried to hold it.

[0009]   In addition, since the wall-mounted chair of the present invention is composed of four links, the chair The large stays 6 and the small stays 8 are arranged in a straight line when the sheets are stored. In this state, If the connecting point between the large stay 6 and the small stay 8 is slightly closer to the frame 1 The seat board 4 and the large stay 6 cannot be pulled down as they are. It Therefore, in the present invention, the connection point between the large stay 6 and the small stay 8 does not exceed the speculation point. As described above, the protrusion 25 is provided on the upper surface of the small stay 8 near the front end so that the protrusion 2 can be stored when the chair is stored. I made 5 contact with the frame 1 so as not to exceed the speculation point.

[0010]   Furthermore, the wall-mounted chair of the present invention maintains the above-mentioned angle and posture when used. Since it is a link mechanism that can be stored on a straight line when not in use, each component has a high Machining and assembly must be done with precise dimensional control. Only However, in the actual processing and assembly site, minute dimensional errors occur and these are accumulated. If they are piled up, the storage operation on the wall 3 will not be performed smoothly after assembly. There is. Therefore, in order to absorb those errors, in the present invention, the portion of the joint shaft 9 is That is, paying attention to the connection point between the large stay 6 and the small stay 8, the lower end of the large stay 6 and the small stay 8 are connected. B. Either one or both of the front end of 8 is a long hole or a sufficiently large hole. , So as to absorb errors in processing and assembly.

[0011]

[Effect of device]

  As described above, according to the present invention, most of the load applied to the seat plate is through the large stay. On the floor surface, and the load on the wall is reduced. Even if it can be installed. Also, since it can be attached to the wall with wood screws, Easy to attach. Furthermore, when not in use, lift the seat plate to the wall frame. By storing it, the stay connected to the seat plate can be folded almost parallel to the wall. It will not interfere with traffic or traffic.
