DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety frame used for a portable toilet.

[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, 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]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides: 1) a short tubular main body, a toilet seat provided on the upper surface of the main body so as to be able to undulate, and an upper surface of the toilet seat provided so as to be undulating.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail by reference examples and embodiments shown in the accompanying drawings. 1 is a perspective view of a main part of a reference example of the present invention, FIG. 2 is a perspective view of an embodiment of the present invention, FIG. 3 (A) is a longitudinal sectional view of a part A in FIG. 2, and FIG. FIG. 4 is a longitudinal sectional view of a part B of FIG.
6 is a vertical sectional view of a part D in FIG. 2, and FIG. 6 is a vertical sectional view of a part E in FIG. The same or equivalent parts in FIGS. 1 and 2 are denoted by the same reference numerals.

This portable toilet is a well-known general-purpose portable toilet (referred to as a general portable toilet currently on the market), and has a height of a toilet seat (37.5 cm).
多 い 38.5 cm) and the occupied area of the main body is slightly different depending on the manufacturer.

The safety frame 5 is configured to be applicable to any portable toilet 1. The safety frame 5 is particularly suitable for a handicapped person who has difficulty walking, but can of course be used for the elderly and the sick.

As shown in FIG. 1, this portable toilet 1 has a short cylindrical (may be bottomed) main body 2 and a toilet tub (bucket) (not Illustrated),
The toilet seat 3 is roughly composed of a toilet seat 3 that can be raised and lowered on the upper surface of the main body 2 and a toilet lid 4 that can be raised and lowered on the upper surface of the toilet seat 3 and covers the toilet seat 3.

A safety frame 5 surrounds the portable toilet 1 as shown in FIG. 1, and has handrails 10 and 10 provided on both sides thereof, and a toilet lid provided at the rear and standing up. And a backrest 13 that does not interfere with the backrest 4.

Therefore, a user such as a handicapped cannot use the handrail 1.
Because the body can be supported by the backrest 13 and the toilet can be used while grasping at zero, the user can safely use the toilet without the helper or by reducing the labor of the helper. It will be convenient.

Since the length of the handrail 10 in the front-rear direction (for example, 560 mm) and the distance between the front legs (posts 8, 8) described later are substantially the same, the safety frame 5 can be used during assembly. It is made into a square shape in plan view, making it compact.

Next, details of the safety frame 5 are shown in FIG.
It will be described according to FIG.

Since the left and right handrails 10 have the same configuration, only one side will be described. However, this handrail 10 is supported in a horizontal front-rear direction by a pair of front and rear columns 8, 9 (also referred to as front legs). Is about 20-25mmφ
Made of structural steel pipe (hereinafter simply referred to as steel pipe)
The handrail 10 and the columns 8, 9 are fixed by welding.

The height of the handrail 10 can be individually adjusted to, for example, five levels on the left and right sides, and the toilet seat 3 of the portable toilet 1 can be adjusted.
To the height of the user's bed, to allow immediate transfer from the bed to the height of the user's bed,
It is possible to adjust the height so that the user can move to the side and sit down by lowering one of them, with the height of 3 being left under the bed. Furthermore, it is easy to sit according to the posture of the user,
The heights of the left and right handrails 10 may be individually adjusted so that the user can stand up and use the toilet.

Therefore, wheelchair users, such as disabled persons,
It is said that it is preferable to shift from the side to the toilet. However, according to the safety frame 5, since it is possible to shift from the side of the wheelchair and sit down, the burden on the person and the attendant can be reduced.

In order to make such an adjustment, the front support 8 supporting the handrail 10 is configured by loosely fitting two large and small steel pipes, and the fitting part is joined by the front joint part 20. .

That is, the front joint portion 20 is
As shown in the figure, the joint is composed of an inverted L-shaped joint made of a synthetic resin such as an ABS resin, and is press-fitted and fixed to the front joint portion 20 from above so as to support the lower end of the upper large-diameter support 8A. The small-diameter column 8B is fitted inside the large-diameter column 8A by inserting the column 8B from below, and the upper-stage steel pipe reinforcing pipe 19A is press-fitted from the lateral direction to be fixed and supported (ie,
It does not come off when folded and stored).

Then, a fitting portion between the large-diameter support 8A and the small-diameter support 8B is fixed by tightening a bolt 21 and a tapping screw hole (referred to as a female screw formed using a tap; the same applies hereinafter) 23. .

That is, one large hole 22 is previously formed in the large-diameter support 8A, and a large number (for example, 5
), And a screw rod of a bolt 21 is passed through a large hole 22 to form a tapping screw hole 2.
3, and the small-diameter support 8B is attracted to the large-diameter support 8A to be brought into close contact therewith. Reference numeral 25 denotes a handle for burying the bolt 21 and rotating it.

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
Are formed by short pipes, and are press-fitted into the rear joint portion 26 and implanted. As shown in FIG. 5, the rear joint 26 is formed of an inverted L-shaped joint made of a synthetic resin such as an ABS resin. Is also inserted and penetrates.

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 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 tapping screw holes 29 and 2 are provided in the middle of the backrest support column 27 in advance.
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 column 27 (or 27A, 27B), so that one of the pair of right and left handrails 10,
(And FIG. 2) as shown in column 27A (one rear leg)
, The other handrail 10 is pivoted in the X direction on the front surface of the backrest 13, and the other handrail 10 is centered on the support 27 </ b> B (the other rear leg).
When the handrail is rotated to the rear surface in the Y direction, the handrails 10 and 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 column 8 and the back column 27 by welding, that is, is connected to the front column 8 and the back column 27 to secure the strength of the columns 8 and 27 in the front-rear direction. The portable toilet 1 is prevented from protruding in the left-right direction.

Of course, the up-and-down adjustment mechanism of the handrail 10 is not limited to the above-mentioned one, and a turnable buckle-shaped rod with a double-ended nut may be used.

The surface of the handrail 10 is covered with a resin cover.
The toilet paper holder wire 32 is inserted into the front joint portion 20 to improve the feel.

Next, details of the backrest 13 will be described.

As shown in FIG. 3A, the backrest 13
Is constructed by bending a steel pipe in a downward U-shape, and a pair of legs 13A is fitted to the back support column 27, respectively, so that the height can be adjusted in two stages, for example.

Incidentally, the height of the toilet seat 3 of the portable toilet 1 currently on the market is 37.5 cm or more as described above.
38.5 cm often, the height of the handrail 10 for that,
Ergonomically becomes 63 cm, and the height of the backrest 13 at that time is about 68 cm in 72 cm to 64 cm,
The height of the tip side of the toilet lid 4 (the height of the tip where the toilet lid 4 stands up is often 67 cm to 80 cm higher than the floor surface, and the height below this is not found).

Then, the steel pipe of the U-shaped connecting portion is formed in a flat shape, and a pillow 33 is attached to the flat portion to form a strip-shaped backrest 13.

The height of the pillow body 33 is substantially the same as the height of the distal end of the upright toilet lid 4 of the portable toilet 1 placed as described above. When the portable toilet 1 is moved rearward by slightly lifting the front part 1 and tilting the standing toilet lid 4 further rearward, the toilet lid 4 can pass through the oblong strip-shaped backrest 13, and thereafter The front side of the portable toilet 1 may be returned to the floor (or the base plate 6).

Surprisingly, the height of the pillow body 33 is unexpectedly near the upper and lower centers of the back of the seated user (toilet seat 4).
Height of about 40cm + 30cm from sitting position = about 70cm)
, And corresponds to the position of the leaning body in the sitting position.
Therefore, it is convenient for a severely handicapped person and also for his / her caretaker. Of course, a user who has a normal upper body can take a comfortable posture and use the device.

As shown in FIG. 6, the feet 13A of the backrest 13 and the backrest support column 27 are fixed by tightening bolts 34 and tapping screw holes 35. That is, a plurality of (for example, two) tapped screw holes 35, 35 are drilled in advance on the distal end side of the backrest support column 27, and a large hole 36 is drilled in the foot 13A of the backrest 13, and a bolt 34 is formed. Through the large hole 35 to support the backrest 2
7 is screwed into the tapping screw hole 35 to support the backrest 2
7 is attracted to the feet 13A of the backrest 13 and fixed in close contact. Reference numeral 38 denotes a handle for burying the bolt 34 and rotating the bolt 34.

Therefore, in order to adjust the height of the pillow 33 of the backrest 13 to the height of the toilet lid 4 of the portable toilet 1, loosen the bolt 34, move the backrest 13 up and down, and 34 can be tightened.

The backrest 13 is formed by bending a steel pipe in a downward U-shape as described above, but furthermore, the leg 13A is bent slightly forward to form a forward inclined portion 39, so that a pillow is provided. Body 3
A space is formed between the toilet lid 3 and the toilet lid 4, so that the back of the seated user does not contact the toilet lid 4. In addition, since such a forward inclined portion 39 is formed, if the forward inclined portion 39 is mounted on the backrest support column 27 so as to be backward, the toilet lid 4 is located in front of the pillow 33. It becomes possible that the toilet lid 4 can be laid down and covered immediately after the stool.

The pillow 33 of the backrest 13 is shown in FIG.
As shown in (A), the cross-sectional shape has a major axis of 90 mm and a minor axis of 4 mm.
It is formed in a 0 mm oval shape, and this oval shape is divided along the major axis. Therefore, the backrest 13 is generally strip-shaped and horizontally long. A bearing portion is formed by a rib 40 into which a flat portion of a steel pipe is inserted in the center of the oval. The two pillows 33 are held together by a screw 41 after holding the flat portion of the steel pipe.

Now, an embodiment of the present invention will be described.

As shown in FIG. 2, the embodiment of the present invention differs from the reference example shown in FIG. 1 in that a base plate 6 is particularly provided. Therefore, the safety frame 5 according to the embodiment of the present invention can be said to be of a high-grade type.

The base plate 6 is formed in a square shape in a plan view, is a PP resin injection molded product having a thickness of about 3 mm, and has a thickness of about 630 m.
It has a size of m □. The smooth plate surface 6A is inclined forward at a slight gradient (slightly inclined to the extent that sewage flows) and at the rear end without inclination.

For this purpose, low banks 16 and 17 on the front side and both sides with the lower end edges flush with each other are provided, and an island-shaped stopper 18 is provided on the rear side. Of course, the banks on the front and both sides may be island-shaped stoppers, and these are referred to as horizontal non-slip stoppers for portable toilets.

It should be noted that the anti-slip stopper allows
In order to prevent the spilled urine from flowing out, as shown in FIG. 2, the banks 16 and 17 on the front side and both sides may be formed as a continuous bank, that is, a bank for preventing sewage outflow.

The portable toilet 1 of any manufacturer can be placed on the plate surface 6A. Therefore, when the portable toilet 1 of a certain manufacturer is placed, some space (for example, a width of 20 mm) is set.
Through one of the banks 16, 17 or the stopper 1
It comes into contact with 8 and becomes non-slip. In particular, this stopper 18
The present invention completely eliminates the feeling of anxiety by completely stopping the backward sliding of the portable toilet 1 when the user is seated.

However, although the portable toilet 1 placed thereon can be moved horizontally by the space, the handrail 10
And a pair of supporting columns 8 and 9 for supporting the
Dangerous movement, that is, jumping out of the portable toilet 1 is prevented by 9 and the like, and since the toilet lid 4 is located at the back of the backrest 13, falling down is also prevented.

The front bank 16 is formed with an inclined surface 16A which is inclined forward to eliminate the step so as not to hinder the user from sitting or standing up. This facilitates the setting on the plate 6. In addition,
The front bank 16 can also store spilled urine, as described above.

The details of the anti-slip foot 15 will be described.

As shown in FIG. 2, on the banks 17 on both sides of the base plate 6, the front support column 8 and the back support column 27 are detachably erected so that the safety frame 5 can be folded. Has been established. These standing structures are the same,
One of them will be described.

That is, as shown in FIG.
