Description

  The present invention relates to a structure of a child chair which has a frame made of a round pipe and can be easily regenerated, and a structure of a simple toilet chair using the child chair.

  As shown in FIGS. 3 and 4, a conventional child chair has a frame 101 made of a round pipe. A seat plate 107 is attached to a parallel supporting round pipe 103 formed in a part of the frame 101 by a rivet 105 (FIG. 3). Since the seat board 107 is made of wood plywood, the layers constituting the plywood come off from the end when used for several years. If the peeled part touches the child's skin, the skin may be rubbed and rubbed, so the chairs are discarded with the plywood life. Although there is no problem with the portion of the frame 101 made of an iron round pipe, the entire chair is discarded with the life of the plywood.

In addition, there are a plurality of techniques that use the elasticity of metal fittings instead of screws or screws to fix the chair seat plate to the pipe. For example, in Patent Document 1, the pipe is fitted along the edge on the back side of the seat plate. What is formed with a groove having an arcuate cross-section is described. Patent Document 2 and Patent Document 3 describe one in which a claw formed on the back side of a seat plate is fitted into a claw hole of a pipe.

  However, in order to replace the seat plate and regenerate the conventional child chair, the rivet is struck with a hammer to deform and drop off, the old seat plate is removed, and then the new seat plate is attached using the new rivet There is a need. Since it takes time to replace the seat plate with rivets, it is difficult to recycle used child chairs.

  Moreover, even if it considers attaching a seat plate with the elasticity of metal fittings by the technique of patent documents 1-3, in patent document 1, it is circular arc shape for a pipe to fit along the edge of the back side of a seat plate. The processing for forming the cross-sectional groove is troublesome, and the manufacturing cost increases. In Patent Documents 2 and 3, it is expensive to form nails and nail holes, which also increases the manufacturing cost.

  Furthermore, if the seat plate can be easily replaced, a child chair can be easily used as a simple toilet chair by providing a hole in the new seat plate. In the event of a disaster such as an earthquake, a large number of people gather as schools as evacuation sites. At that time, one of the most worrisome problems is how to secure a toilet. One of the most worrisome problems can be solved if children's chairs that already exist in the evacuation school can be used as simple toilet chairs.

  In order to solve the above problems, the present invention facilitates the regeneration of child chairs, does not increase the manufacturing cost, and can solve the problem of securing toilets in disaster evacuation areas. The purpose is to provide simple toilet chairs using child chairs.

  In order to solve the above problems, the first device is a framework composed of a metal round pipe, a parallel support round pipe formed on a part of the framework and supporting the lower surface of the seat plate, and the support An easily reproducible child chair characterized by having a seat plate in which a parallel metal fitting round pipe that fits in contact with the inside or outside of the round pipe is fixed to the lower surface.

  The second device is a frame composed of a metal round pipe, a parallel support round pipe formed on a part of the frame and supporting the lower surface of the seat plate, and a seat attached to the support round pipe by rivets. For the fitting of parallel metal fitting in contact with the inner side or the outer side of the frame from which the seat plate is removed using a used child chair having a plate, and the supporting round pipe of the frame A seat plate with a round pipe fixed to the lower surface, a hole provided in the seat plate, and a bag attached by sandwiching the left and right portions of the opening edge between the support round pipe and the fitting round pipe A simple toilet chair using a child chair characterized by having

  According to the first device, the mounting of the seat plate is a metal fitting round pipe fixed to the lower surface of the seat plate with respect to the parallel supporting round pipe formed on a part of the frame made of a metal round pipe. Press firmly from top to bottom. As a result, the fitting round pipe comes into contact with the inside or outside of the supporting round pipe and slides downward while fitting, while causing elastic deformation. To remove the seat plate, tap the lower surface of the seat plate upward with a wooden mallet. As a result, the fitting round pipe comes into contact with the inside or outside of the supporting round pipe and slides upward, and the fitting is released while causing elastic deformation.

By pressing strongly or hitting with a wooden mallet as described above, the seat plate can be easily replaced, and the used child chair can be easily regenerated. Moreover, since it is only necessary to fix the metal fitting round pipe parallel to the lower surface of the seat plate, the manufacturing cost of the chair is not increased.
According to the second device, a simple toilet chair can be prepared by using a used child chair, removing the old seat plate from the frame, and fixing the fitting round pipe to the lower surface of the seat plate provided with holes. Therefore, many child chairs that already exist in the school as an evacuation site can be used as simple toilet chairs. In the event of a disaster such as an earthquake, a large number of people gather as schools as evacuation sites, and the problem of securing a toilet as one of the most worrisome problems can be solved easily. Furthermore, as in the first device, the seat plate can be easily replaced by pressing it hard or hitting it with a mallet. Bags that are sandwiched and attached can be easily replaced, and therefore, the function as a sanitary and simple toilet can be enhanced.

An embodiment of this invention is shown in FIGS.
This embodiment relates to a simple toilet chair 1 using a used child chair.

(framework)
For this reason, the framework 3 of the simple toilet chair 1 is the same as that of a conventional child chair. That is, the frame 3 made of a metal round pipe is positioned with the downward U-shaped leg frame member 5 facing the upper side 7 of the downward U-shaped in the front-rear direction of the chair. A pair of the leg frame members 5 are arranged at a predetermined interval in the left-right direction of the chair. Accordingly, four legs 9 are formed. The rear side 11 of the downward U-shape is welded to each end portion of the link member 13 positioned in the right and left direction of the chair, and thus the pair of left and right leg frame members 5 are connected.

A pair of L-shaped back plate frames 17 are disposed on the left and right sides of the back plate 15. Each L-shaped vertical side 19 is attached to the back plate 15 by a rivet 21. Each L-shaped lateral side 22 is in contact with the rear part of the upper side 7 of the leg frame member 5 along the inner side, and is connected by welding.
The framework 3 is configured as described above.

(Seat)
The upper sides 7 of the pair of left and right leg frame members 5 that are a part of the framework 3 form a pair of parallel support round pipes 23 that support the lower surface of the seat plate 24.
A pair of fitting round pipes 25 to be fitted to the pair of supporting round pipes 23 are fixed to the left and right of the lower surface of the seat plate 24. The fitting round pipe 25 is located in the front-rear direction, and is located in parallel with the supporting round pipe 23 after fitting. This fixing is performed by overlapping the seat plate 24, the spacer 27, and the fitting round pipe 25 vertically and penetrating the rivet 26. The fitting round pipe 25 is positioned below by the amount of the spacer 27, so that a moderation feeling at the time of fitting can be obtained.

This fitting is performed by causing the pair of fitting round pipes 25 to contact the inside of the pair of supporting round pipes 23 and causing elastic deformation. The fitting round pipe 25 is arranged in front of the L-shaped lateral side 22 of the back plate frame 17 in the same manner in the front-rear direction of the chair after fitting.
In the center of the seat plate 24, a hole 29 for stool is provided. A bag 31 for receiving feces is attached to the lower side of the seat plate 24. That is, the bag 31 can be easily attached by sandwiching the left and right portions of the opening edge 33 of the bag 31 between the supporting round pipe 23 and the fitting round pipe 25.

"Effects of Embodiment"
(Attaching the seat plate)
According to this embodiment, attachment of the seat plate 24 is performed by pressing the seat plate 24 strongly downward. That is, the metal fitting round pipe 25 fixed to the lower surface of the seat plate 24 is strongly pressed from the top to the bottom against the parallel supporting round pipe 23 formed on a part of the frame made of a metal round pipe. . As a result, the fitting round pipe 25 comes into contact with the inside of the supporting round pipe 23 and slides downward while fitting, while causing elastic deformation. The fitting round pipe 25 is positioned below the support round pipe 23 by the amount of the spacer 27. Therefore, the fitting round pipe 25 gets over the support round pipe 23 and is thus fitted. A feeling is fully obtained.

(Removing the seat plate)
Removal of the seat plate 24 is performed by strongly hitting the lower surface of the seat plate 24 upward with a mallet or the like. As a result, the fitting round pipe 25 comes into contact with the inside of the supporting round pipe 23 and slides upward, and the fitting is released while causing elastic deformation.
