Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seating assisting device which is effective when a user who has low muscular strength of the legs and legs uses a toilet.

[0002]

2. Description of the Related Art When a user with weak muscular strength of the legs and legs excretes, it may not be easy to sit on the toilet seat of the toilet or stand up. In such a case, it may be necessary to assist a caregiver. is there.

[0003] However, it is not easy to assist a user who has weak muscles in the legs and hips to stand up or sit down, and the burden on the assistant is large. Therefore, it is desired to reduce the burden on the assistant. I have.

[0004] Generally, a toilet seat provided on a toilet is rotatably attached to the toilet with its rear end as a fulcrum, and when used, is held on the toilet in a state of lying down substantially horizontally. Therefore, when the user sits on the toilet seat, the user must lower the buttocks deeply to the height of the toilet seat.

Further, when the user stands up, the buttocks which have been lowered deeply into the toilet seat must be lifted, and the legs must be extended from the bent state, which places a greater burden on the user than sitting down.

Accordingly, the present applicant has filed Japanese Patent Application No. 2000-30.
No. 5188 has proposed a toilet seating assistance device. In the toilet seat assisting device of this application, a front end of a frame to which a valve seat is attached is rotatably connected to an upper portion of a front end of a main body. A link mechanism is provided between the main body and the frame, and the frame is urged by a gas spring in an upright direction.

The main body is provided with rotatable handles as operation members located on both sides of the frame. This handle is connected to the link mechanism. Then, when the user operates the above handle,
The valve seat can be slowly rotated when the user sits on the toilet or stands up.

[0008] Thus, without using a gas spring having a large urging force, the handle can be used to suppress the rotation speed of the frame in the falling direction when seated, so that the frame can be gently seated. If the user is encouraged to rotate in the upright direction, the user can sit down or stand up so that a heavy load is not applied to his / her feet and hips.

[0009]

According to the toilet seating assisting device having such a configuration, the user can certainly reduce the burden on his / her feet when sitting or standing up.

Incidentally, a gas spring provided between the frame and the link mechanism urges the frame in a rising direction with a predetermined urging force. Therefore, when the user sits down, the frame is rotated in the falling direction against the urging force of the gas spring, and the collapsed frame is rotated in the upright direction by the urging force of the gas spring. Become.

For this reason, it is preferable that the urging force of the gas spring be changed according to the weight of the user. For example, when the weight of the user is light, the biasing force of the gas spring is weakened, so that the frame can be easily laid down while sitting down, and it is preferable that the buttocks are not strongly pressed when standing up. .

For a heavy user, the urging force of the gas spring is increased to prevent the falling speed of the frame from becoming too fast when seated.
It is better to be able to push up the buttocks when standing up.

However, conventionally, the strength of the gas spring has not been changed in accordance with the load of the user. Therefore, when a user having a different weight uses the gas spring, the user can comfortably sit or stand up. Was sometimes impaired.

Further, a handle for assisting the rotation of the frame is provided with a predetermined length and at a predetermined angle when the frame is laid down, and its length and angle can be changed. It wasn't.

[0015] Therefore, when users of different physiques use it, it may be difficult to use,
There were things that got in the way when I got up.

It is an object of the present invention to provide a toilet seating assisting device which can change the urging force for urging a frame by a gas spring when used by users of different weights.

Accordingly, the height of the front grounding member 7 can be adjusted by a pair of height adjusting nuts 14 and 17, and each of the bolts 13 and 16 has the through hole 12 and the insertion hole 19.
Is inserted in a state where there is a play, so that it can swing with respect to the main body 1.

The front end of the front grounding member 7 attached to the lower end of the side member 2 projects forward by a predetermined distance from the front end of the lower horizontal portion 3a of the side member 2, as shown in FIG.
Thus, the rear end of the main body 1 in the front-rear direction by the pair of front grounding members 7 is prevented from rising and rotating forward.

Further, by rotating the height adjusting nut 17 in the ascending direction to support the lower horizontal portion 3a, the side member 3 is prevented from rattling against the front grounding member 7.

A pair of non-slip members 20 made of sheet rubber or the like are attached to the lower surface of the front grounding member 7.

The rear grounding member 8 has a disk shape, and a convex portion 21 is formed at the center thereof so as to protrude toward the upper surface.
A non-slip member 22 is adhered to the lower surface. A through hole 21a is formed in the convex portion 21, and a bolt 23 having a crimped head is inserted into the through hole 21a with a play. A third height adjusting nut 24 is screwed into a screw portion of the bolt 23 protruding on the upper surface side of the rear grounding member 8.

The bolt 23 is screwed to a mounting nut 26 fixed to the lower surface of the lower horizontal portion 3a of the side member 2. Thus, the rear grounding member 8 can be adjusted in height by the third height adjusting nut 24, and can be swung by the bolt 23 being inserted into the through hole 21a in a loose state. It has become.

Therefore, even if the floor on which the main body 1 is installed has an inclination or unevenness, the installation members 7 and 8 swing according to the inclination and unevenness of the grounding portion, and the grounding is reliably performed.
The main body 1 can be installed in a stable state without rattling on the floor surface.

The side member 2 is provided with a first height adjusting nut 14.
And the third height adjusting nut 24 can adjust the height. After turning the nuts 14 and 24 to move the front grounding member 7 and the rear grounding member 8 up and down to adjust the height of the side member 2, turn the second height adjusting nut 17 in the ascending direction to lower the lower member. When the horizontal portion 3a is pressed, the front grounding member 7 can be held so as not to swing with respect to the side member 2.

Thus, even if the front grounding member 7 and the rear grounding member 8 are provided to be swingable, the main body 1 can be installed without rattling on the floor surface.

As shown in FIGS. 1 and 2, a pair of side members 2
A mounting piece 27 is fixed near the top of the rising portion 3b. Both ends of the front end of the frame 28 are rotatably connected to the pair of mounting pieces 27. In other words, this frame 28 is formed by bending a pipe material into a substantially U-shape, and both ends, which are front ends, are formed outward in substantially L-shaped bent portions 28a. Is pivotally attached to the mounting piece 27 by a support shaft 29.

As shown by a chain line in FIG.

In the present invention, the toilet seat 34 is removed from the toilet bowl 41 and the frame is removed. 28 is attached via the holding member 31. Note that a water tank 40 is integrally provided at the upper end of the toilet 41.

The horizontal portion 4a of the holding member 4 is held at the rear end of the toilet 41 from which the toilet seat 34 has been removed.
That is, the shaft-like elastic member (not shown) is passed through the mounting hole 4b formed in the horizontal portion 4a and the through hole formed in the rear end portion of the upper surface of the toilet 41, thereby holding the toilet 41. The main body 1 is elastically held via the member 4.

That is, when the main body 1 is fixed to the toilet 41 using, for example, bolts or the like, an external force is applied to the main body 1 and the toilet 41 may be damaged. It is held elastically.

As shown in FIG. 1, a link mechanism 45 is provided between the reinforcing member 5 of the pair of left and right side members 2 and the frame 28. The link mechanism 45 is driven by a handle 46. The handle 46 has a tubular fixing member 46a and an L-shaped handle member 46b slidably provided on the fixing member 46a.
As shown in FIG. 4 or FIG. 6, a bracket 47 is provided on the fixing member 46a, and an upper end of the bracket 47 is pivotally connected to the reinforcing member 5 by a pin 44.

The handle member 46b of the handle 46
Can be fixed at a predetermined sliding position with respect to the fixing member 46a. That is, as shown in FIG. 5, a U-shaped spring 51 is housed in a compressed state in the lower end portion of the handle member 46b. An engagement pin 52 is provided at one end of the U-shaped spring 51. The engagement pin 52 projects from a through hole 53 formed in the peripheral wall at the lower end of the handle member 46b, and a plurality of engagement holes 54 formed at predetermined intervals along the height direction on the peripheral wall of the fixing member 46a. One resiliently engages.

Therefore, by engaging the engaging pin 52 with the engaging hole 54 of a predetermined height, the handle member 46b can be held at the height position shown by the solid line in FIG. 4 or the height shown by the chain line. I can do it. The engagement hole 54
The holding height of the handle member 46b can be changed according to the number.

One end of a movable link 56 is pivotally connected to the lower end of the bracket 47 by a pin 57. A plurality of, in this embodiment, three connecting holes 59 are formed at one end of the movable link 56 at predetermined intervals, and the pin 57 is inserted into one of them.

A base end of a fixed link 58 is fixed to a halfway portion on both sides of the frame 28. The front end of the fixed link 58 extends toward the front of the main body 1,
The other end of the movable link 56 is pivotally attached to its front end.

Accordingly, when the handle 46 is turned forward and downward from the state shown by the solid line in FIG. 6 as shown in FIG. 7, the frame 28 provided with the toilet seat 34 is connected to the mounting piece 27 at the front end. With the part as a fulcrum, it can be rotated upward in a rising direction from a substantially horizontal state.

Depending on which of the three connection holes 59 formed at one end of the movable link 56 is connected to the lower end of the bracket 47, when the toilet seat 34 is in a substantially horizontal state, The angle of inclination along can be adjusted. That is, the handle 46 is
Can be held at a position indicated by a solid line as shown by a dotted line, and a position inclined at a predetermined angle forward and rearward of the position indicated by a solid line as indicated by a chain line.

By changing the inclination angle of the handle 46 in the front-rear direction as shown in FIG. 6 or changing the height as shown in FIG. 4, the handle 46 can be easily operated according to the user's physique and the like. Can be positioned.

The handle member 46b of the handle 46
Can be removed from the fixing member 46a. Therefore, by removing the handle member 46b protruding above the toilet seat 34 of the one handle 46, if the user has a physical disability, for example, a user who cannot move his / her half freely, sit on the toilet seat 34. It can also be easier. In addition, in the case of such a user, since only one of the handles 46 can be operated, there is no operational problem even if the handle member 46b of the other handle 46 is removed.

One end of a gas spring 61 is pivotally connected to the horizontal portion 3a of the one side member 2. The other end of the gas spring 61 is pivotally connected to a connecting portion 62 provided behind the fixed link 58 on both sides of the frame 28, whereby the frame 8 is raised by the gas spring 61 in a rising direction. Being energized.

As shown in FIG. 7, the connecting portion 62 has a plurality of mounting holes 63a to 63c formed at predetermined intervals in the vertical direction. The other end of the gas spring 61 is connected to any one of the three mounting holes 63a to 63c.

Depending on which of the three mounting holes 63a to 63c the other end of the gas spring 61 is connected to, the force required when the frame 28 that has been rotated and raised can fall can be changed.

That is, the gas spring 61 has a lower end mounting hole 6 as shown by a chain line as compared with a case where the other end is connected to the uppermost mounting hole 63a as shown by a solid line in FIG.
3c, the angle formed with respect to the frame 28 is smaller. When the inclination angle of the gas spring 61 with respect to the frame 28 is reduced, when the extended gas spring 61 is pressed in the contracting direction via the frame 28, it is difficult to operate in the contracting direction. Becomes larger.

That is, the load for rotating the frame 28 in the falling direction can be changed. Therefore, even if the load applied to the toilet seat 34 changes due to the weight of the user or the like, the connecting member 6 that connects the other end of the gas spring 61
By changing the positions of the second mounting holes 63a to 63c, the speed at which the frame 28 (toilet seat 34) rotates in the falling direction when seated can be adjusted.

The number of connecting holes formed in the connecting portion 62 is not limited to three, but may be two or four or more.

As shown in FIG. 4, a base end of a stopper 65 formed at a hook-like engaging portion 64 at the tip thereof is rotatably connected to a middle portion of the movable link 56. The engaging portion 64 of the stopper 65 engages with a locking pin 66 protruding from the outer surface of the fixed link 58 when the frame 28 is lowered from the upright state to a substantially horizontal position.
Thus, the frame 28 is held in a substantially horizontal state against the urging force of the gas spring 61, and is prevented from rotating in the upright direction.

An operation pin 67 is projected from an intermediate surface of the stopper 65, and the engagement pin 64 is disengaged from the locking pin 66 by rotating the stopper 65 with the operation pin 67. be able to.

As shown in FIG. 1, FIG. 2 or FIG. 8, both ends of a mounting rod 71 bent in a mountain shape are fixed to the front ends of the lower horizontal portions 3a of the pair of side members 2. The mounting rod 71 is provided with a tensioning means 70. The strut means 70 has a tubular member 72 having an intermediate portion fixed to the top of the mounting rod 71. This tubular member 72
Is formed to be equal to or slightly longer than the width of the main body 1, and bar-shaped members 73 are provided at both ends thereof so as to be able to protrude and retract. The pair of rod-shaped members 73 are connected to the tubular member 7.
2 can be fixed at an arbitrary projecting length by stopper screws 74 provided at both ends.

As shown in FIG. 8, the rod-shaped member 73 is fixed with its tip protruding so as to contact the side wall 75 of the room R in which the toilet 41 is installed. This prevents the main body 1 from shifting in the width direction in the room R.

A case where the toilet seating assisting device having such a configuration is used will be described. As shown in FIG. 9B, before the user U sits on the toilet seat 34, the toilet seat 34 is in an upright state at a predetermined angle by the urging force of the gas spring 61.

When the user U sits on the toilet seat 34 in this state, the user U faces backward as shown in FIG. 9B, grasps the distal ends of the pair of handles 46 with both hands, and then sits down. Put down the buttocks on the toilet seat 34. By gradually lowering the buttocks in this state, the lower surface of the frame 28 provided with the toilet seat 34
Until the gas spring 61 comes into contact with the upper surface, the gas spring 61 rotates in the falling direction against the urging force of the gas spring 61.

Therefore, since the user U can sit while the buttocks are supported by the toilet seat 34, the user U can sit without imposing a large burden on the waist and the legs.

In addition, when the user U is seated, the handle 46 gripped by the user U is linked with the rotation of the toilet seat 34 in the falling direction.
Therefore, the user U can change the speed at which the toilet seat 34 rotates in the falling direction by adjusting the force applied to the handle 46. The seat can also be seated with the rotation speed of the downturn 34 in the falling direction further reduced.

Further, since the user U holds the handle 46 when he / she sits down, the operation can be performed stably without shaking the body.

In the case where the user U who stands down with the toilet seat 34 lying down to a state where the toilet seat 34 is joined to the upper surface of the toilet 41,
The user grips the distal end of the handle 46 and moves the weight upward of the handle 46. As a result, weight is added to the tip of the handle 46, and the user U moves the handle 46 to the position shown in FIG.
(A) It can be easily rotated in the direction shown by the arrow.

When the handle 46 is rotated in the direction shown by the arrow in FIG. 9A, the frame 28 provided with the toilet seat 34 is rotated by the link mechanism 45 to rotate the frame 29 on the front end side.
Is pivoted in the direction in which the user U stands up, so that the user U has his buttocks pushed up. At this time, since the urging force of the gas spring 61 is applied to the frame 28, the force for pushing the handle 46 forward can be reduced.

Therefore, the user U can push up the buttocks diagonally forward by operating the handle 46 with a relatively light operating force, and can stand up without imposing a heavy burden on the legs and hips. Also at this time, since the user U is holding the handle 46 and the toilet seat 34 is in contact with the buttocks, the user U can surely hold the body until the condition of the legs and hips is stabilized.

When the user U stands up by pressing the handle 46 forward, a moment is generated in the main body 1 at which the rear end rises with the front end as a fulcrum, that is, a moment in the turning direction of the handle 46 is generated. However, since the front grounding member 7 provided on the main body 1 has a front end portion projecting forward from the front end of the side member 2 by a predetermined size, the protruding portion prevents the main body 1 from rotating forward. .

The front grounding member 7 and the rear grounding member 8 are swingably provided at the lower end of the side member 2 of the main body 1. Therefore, the floor of the room R in which the main body 1 is installed is inclined,
Even if there is unevenness, it swings according to the state and joins without rattling on the floor surface.

Therefore, when the user U sits or stands up, even if the user grips the handle 46 and applies a force to the main body 1, the main body 1 does not rattle on the floor surface.
The user U can sit and stand in a stable state.

Further, the main body 1 installed in the room R is fixed in a state where the rod-shaped member 73 of the tension means 70 is in contact with the side wall 75. Therefore, even when an external force is applied to the main body 1, the main body 1 is unlikely to move in the width direction or the front-back direction in the room R, so that the user U can sit or stand in a stable state.

The handle 46 can be adjusted in height and tilt angle in the front-rear direction. Therefore, by adjusting the height and the inclination angle of the handle 46 according to the user U's physique and the like, it is possible to make it easy to use. That is, the physical burden on the user U can be reduced.

The handle 46 includes a fixed member 46a and a handle member 46b, and the handle member 46b can be removed from the fixed member 46a. Therefore, if the handle member 46b of one handle 46 of the pair of handles 46 is removed, one side in the width direction of the toilet seat 34 is opened.
You can sit on and stand up.

For example, a user U who has a disability
In such a case, the user may hit the body against one of the handle members 46b when sitting or standing up,
By removing one handle member 46b as described above, without hitting the body against the handle member 46b,
Can easily stand up and sit down.

The gas spring 61, which urges the frame 28 provided with the toilet seat 34 in the upright direction, can be attached to the attachment hole 63 of the connecting portion 62 provided in the frame 28 by changing the angle with respect to the frame 28.

By changing the mounting angle of the gas spring 61 with respect to the frame 28, the
The minimum load required to rotate the in the downturn direction can be changed. That is, the gas spring 61 is connected to the connecting portion 62.
By connecting to the mounting hole 63c at the lower end of the
If the angle formed by the gas spring 61 with respect to 8 is reduced, the minimum load required to make the frame 28 fall down is increased.

For example, in the case of the user U having a heavy weight, the gas spring 61 is connected to the mounting hole 63c at the lowermost end of the connecting portion 62 so as to increase the load required for the frame 34 to fall down. Thereby, when the user U having a heavy weight sits down, the rotation speed of the frame 34 in the falling direction can be moderated, so that the user U can sit down without imposing a sudden load on the legs and hips.

On the other hand, in the case of the user U having a light weight, the gas spring 61 is connected to the uppermost mounting hole 63a of the connecting portion 62 of the frame 34 so that the load required for the frame 34 to fall down is reduced. . Thus, the user U does not strongly press the buttocks on the toilet seat 34 and
Can be seated relatively easily and without putting a burden on the buttocks. For example, in the case where the user U has a sore on the buttocks, it is possible to reduce the feeling of discomfort and pain due to the pressure on the buttocks.

The other end of the gas spring 61 is connected to the connecting portion 62.
When the frame 28 is connected to the mounting hole 63 at the lower end of the frame 28, the moment for rotating the frame 28 in the upright state in the upright direction is greater than when the frame 28 is connected to the mounting hole 62 at the upper end.

Therefore, by connecting the gas spring 61 to the mounting hole 63c at the lowermost end of the connecting portion 62, even if the user U has a heavy weight, the user's U's buttocks can be reliably pushed up. It becomes possible.

On the other hand, in the case of the user U having a light weight, the gas spring 6 is inserted into the uppermost mounting hole 63a of the connecting portion 62.
Connect 1 As a result, the moment acting on the fallen frame 28 is reduced, so that the user U can be prevented from being pushed up strongly.

That is, by changing the attachment angle of the gas spring 61 with respect to the frame 28, even if the weight of the user U changes, the rotation speed of the frame 28 when sitting or standing can be prevented from greatly changing. can do.

The present invention is not limited to the above embodiment, but can be variously modified. For example, in the above-described embodiment, the toilet seat is rotated from the lying state to the upright state by pushing the handle forward, but if the structure of the link mechanism is changed, the toilet seat is pulled up by pulling the handle. You may make it rotate.

[0088]

As described above, according to the present invention, since the other end of the gas spring whose one end is pivotally attached to the main body is pivotally attached to the frame so that the angle between the frame and the frame can be changed, these frames and the gas spring are connected. By changing the angle formed by the gas spring, the restoring force acting on the frame by the gas spring can be changed.

For this reason, when a lightly weighted user is seated, the force for rotating the frame in the falling direction and the force for rotating the frame in the upright direction are weakened. Since the force for moving and the force for turning in the upright direction can be increased, it is possible to prevent the turning speed of the frame from greatly changing even if the weight of the user changes.

Further, according to the present invention, since the inclination angle of the operation member can be changed, it is possible to set the inclination angle of the operation member in a state that can be easily used according to the user.
