Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety frame for use in portable toilets and Western style toilets.

[0002]

2. Description of the Related Art As is well known, portable plastic toilets (hereinafter referred to as portable toilets) are widely used in hospital rooms and elderly people's bedrooms. A main body (referred to as a toilet body), a toilet tub suspended from the main body so as to be freely taken out, a toilet seat that is automatically raised and lowered on the upper surface of the main body, and a toilet lid that can be freely raised and lowered on the upper surface of the toilet seat, Approximately.

[0003] On the other hand, wheelchairs called sanitary chairs have long been used in toilets used by persons with difficulty walking, such as the handicapped, elderly and sick, and these sanitary chairs are provided horizontally on both sides in the front-rear direction. A wheelchair including a handrail (hereinafter simply referred to as a handrail, also referred to as an armrest), a backrest provided at a rear portion, a seat plate having a large hole in the center, and the like,
Usually, it can pass over a Western-style toilet installed in a toilet.

[0004] And, this handrail is particularly handicapped,
A safe operation can be performed by sitting on the seat plate or grasping when standing up, and the backrest can support the body during the stool of the handicapped.

[0005] Therefore, a portable toilet with a safety frame combining a portable toilet and a sanitary chair (for example, see Japanese Utility Model Publication No. 52-10867) has been provided and has been well received.

In addition, instead of a wheelchair called a sanitary chair, a safety frame with a handrail surrounding a Western-style toilet bowl has been proposed (for example, see Japanese Utility Model Laid-Open No. 23997/1993).

By the way, a safety frame used for the portable toilet and a safety frame with a handrail surrounding a Western-style toilet bowl.
The safety frame is stored because it is no longer necessary to recover the user's physical disability, the portable toilet itself is unnecessary, and the safety frame is compacted during packing and transportation. Accordingly, there is a demand for disassembling and assembling and miniaturization as much as possible.

Therefore, a proposal has been made to make such a safety frame disassemble and assemble and to make it compact. For example, Japanese Unexamined Utility Model Publication No. Hei 6-11592 discloses the following safety frame that can be disassembled and assembled.

This will be described with reference to FIG. The safety frame 50 is formed of a frame pipe in the same manner as a normal chair. In particular, a pair of front legs and a pair of rear legs 51, 52,. Railings 55, 55,
A backrest 56 at the rear and a left and right connecting rod 57 at the rear are integrally formed.

In order to disassemble and assemble the safety frame 50, the safety frame 50 can be divided into two parts as viewed from the front, that is, a pipe of a backrest 56 and a left and right connecting rod 57.
The pipe can be divided into two parts, and at the division position, a connecting insert 58 is protruded from one of the pipes and can be inserted into and removed from the other pipe, and the connecting insert 58 inserted into the pipe is screwed. The stopper is fixed.

[0011]

However, in the proposed safety frame 50, when it is divided into two parts, a width of only L is required as viewed from the front as shown in the figure, which is sufficient for the above demand for compactness. In particular, when disassembled, the connecting insert 58 is easily damaged because the thin connecting insert 58 inserted into the frame pipe is protruded, and if it is damaged, it may be damaged during assembly. There is a problem that it becomes difficult to insert into the pipe.

The inventors of the present invention have changed the idea of dividing the safety frame into a compact form, and have conceived the idea of making the safety frame compact so as to make it still compact, that is, a problem.

[0013]

Therefore, in order to adjust the height of the handrail 10, the bolt 21 is loosened, and the small-diameter support 8B is connected to the large-diameter support 8.
A may be inserted and removed, and the bolt 21 may be tightened again.

A rear support 9 for supporting the handrail 10 is also provided.
Are formed by short pipes, and are press-fitted into the rear joint portion 26 and implanted. As shown in FIG. 6, the rear joint 26 is formed of an inverted L-shaped joint made of a synthetic resin such as ABS resin. The rear joint 26 is provided with a steel pipe back support column 27 (FIG. 1). Is also referred to as a hind leg).

Further, the upper reinforcing pipe 19A is pressed into the rear joint portion 26 from the lateral direction and fixed and supported (that is, it does not come off when it is folded and stored). Therefore, the rear support 9 is planted between the end of the upper reinforcing pipe 19A and the support 27 for the backrest. The rear joint 26 and the backrest support column 27 are connected to the bolt 28 and the tapped screw hole 29.
It is fixed by tightening.

That is, a large number (for example, five) of tapped screw holes 29, 2 are previously provided in the middle of the back support column 27.
9 are drilled in accordance with the positions of the tapping screw holes 23 drilled in the small-diameter support 8B, and the threaded rods of the bolts 28 are screwed into the tapping screw holes 29 of the support 27 for the backrest. The part 26 and the back support column 27 are fixed.
Reference numeral 31 denotes a handle for burying the bolt 28 and rotating it.

Therefore, in order to adjust the height of the handrail 10, it is sufficient to loosen the bolt 28, move the rear joint 26 up and down with respect to the back support column 27, and tighten the bolt 28 again. For this reason, the rear joint 26 made of synthetic resin and the support column 27 made of metal are slid, so that a smooth vertical movement can be achieved even in a close fitting.

Then, a pair of legs 13A of the backrest 13,
13A is rotatably fitted to the back support pillar 27 (or 27A, 27B), so that one of the pair of left and right handrails 10, 10 is used as a support as shown in FIG. By turning the backrest 13 in the X direction around the front of the backrest 13 around the 27A (one rear leg) and turning the other handrail 10 around the column 27B (the other rear leg) in the Y direction, The handrails 10, 10 are folded with the backrest 13 therebetween.

Therefore, it is convenient for transporting and storing the safety frame 5, for example, it does not take up space, and can be handled compactly as used bulky waste. In particular, the folded thickness can be the thickness of the pair of handrails 10, 10 and the backrest 13 side.

The lower reinforcing pipe 19B is fixed to the front support 8 and the back support support 27 by welding, respectively, that is, they are connected to each other to secure the strength of these supports 8 and 27 in the front-rear direction. The portable toilet 1 is prevented from protruding in the left-right direction.
