Description

  The present invention relates to a handrail structure of a toilet bowl and a toilet bowl for movement.

For toilets and portable toilets used by elderly and handicapped persons, it is necessary to transfer from a wheelchair to the toilet seat (hereinafter referred to as “transfer”) and to get up safely from the toilet seat. A slide is provided.
On the other hand, elderly people often have a round back and often bend forward even when seated on a toilet seat during a toilet.

In addition, when older, due to defecation disorder, even when sitting on the toilet seat, it is not possible to defecate smoothly, and the time spent sitting on the toilet seat tends to increase.
Therefore, a handrail device having a front handrail has been proposed in order to support the body so that it does not fall greatly forward even when sitting for a long time (Patent Document 1).

  That is, this handrail device supports a front handrail at the tip of one handrail among the side handrails provided so as to sandwich the toilet seat from both sides, and rises from the toilet seat when seated on the toilet seat. Occasionally, the front handrail is kept upright so that the front handrail does not get in the way. The user who is seated in can support the body so that it does not fall forward with arms or hands.

JP 2011-19805 JP

By the way, in the case of the handrail device described above, the front handrail must be raised on one side handrail side when sitting or standing, and one side handrail tip side. The load on the front handrail is concentrated on the balance and the balance is poor. In particular, when such a handrail device is used in a toilet bowl for movement, the toilet bowl may fall down unless the toilet body is made heavy when changing to a toilet seat.
However, if the toilet bowl is too heavy, it cannot be easily moved.

In the case of the handrail device, if the user tries to put his elbow safely on the front handrail, it is necessary to bring the front handrail closer to the toilet seat to some extent.
However, if the front handrail is brought close to the toilet seat, the user may feel a pressure when using the front handrail while standing, and there is a risk of stressing the user.

  Further, in the case of the handrail device described above, the front handrail is disposed at a right angle to the front direction of the user at the forward tilt prevention position, so that the user tries to receive the entire forearm by the front handrail. Then, it is easy to put a burden on the shoulder.

  In view of the above circumstances, the present invention provides a handrail structure for a toilet bowl that can easily support the forearm portion and prevent forward tilt without the user feeling a sense of pressure, and a moving toilet equipped with the handrail structure. It is intended to provide.

  In order to achieve the above object, the handrail structure of a toilet according to the present invention (hereinafter referred to as “handrail structure of the present invention”) is such that two side handrails sandwich the toilet seat from the side. The handrail structure of the toilet bowl provided, wherein the two side handrails each include a side handrail main body portion and a forearm support arm, and the forearm support arm includes the side handrail main body. An armrest position that overlaps the upper part and one end protrudes forward of the toilet seat, and a substantially C shape is formed with the other forearm support arm. The other end portion is pivotally supported by the side handrail main body portion so that the user can rotate while seated on the toilet seat.

In the handrail structure of the present invention, the forearm support arm has a lateral handrail main body so that the rotation angle from the armrest position to the forward tilt prevention position is more than 90 degrees and less than 180 degrees (preferably 120 to 140 degrees). It is preferable that it is pivotally supported by the part.
That is, when the forearm support arm is rotated from the armrest position to the forward tilt prevention position, or from the forward tilt prevention position to the armrest position, the forearm support arm never protrudes outward in the width direction of the toilet seat. Therefore, the toilet can be installed with almost no gap between the toilet and the wall or bed, and the selectivity of the installation position of the toilet is high.

  A moving toilet according to the present invention (hereinafter referred to as “moving toilet of the present invention”) includes a side rail of the handrail structure of the present invention.

The moving toilet of the present invention is a toilet main body in which the side handrail is overlapped with at least the forearm support arm of the side handrail main body so that the upper surface of the forearm support arm can be lowered to the height position of the toilet seat. It is preferable that the structure is supported by the structure.
That is, when the toilet bowl for movement is installed so that one side handrail is along the bedside or the like, at least a portion of the side handrail main body overlapped with the forearm support arm is overlaid on the forearm support arm. In this state, if the part of the side handrail body that is overlapped with at least the forearm support arm is lowered so that the upper surface of the forearm support arm is at the toilet seat height, the transfer from the bed or the like to the toilet seat can be performed smoothly.
Moreover, transfer from a wheelchair etc. can also be performed easily.

  As described above, the handrail structure of the present invention is a handrail structure for a toilet bowl in which two side handrails are provided so as to sandwich a toilet seat from the side, and the two side handrails are provided. Has a side handrail main body part and a forearm support arm, and the forearm support arm has an armrest position that overlaps the side handrail main body part, one end projects forward of the toilet seat, and the other forearm support A generally square shape is formed between the arm and the forward tilting position so that the user can select a position that prevents the body from falling forward, and the end can be rotated while seated on the toilet seat. Is pivotally supported by the side handrail main body.

Therefore, by setting the forearm support arm in the armrest position that overlaps the side rail main body, it is possible to safely and easily transfer to the toilet seat from a wheelchair etc. with the side handrail and stand up from the toilet seat. Can be transferred to a wheelchair.
Then, after sitting on the toilet seat, the side handrail can be used as an armrest, and when the forearm support arm is rotated to the fore-fall prevention position, the user in a forward leaning posture causes the forearm support arm to support the forefoot. , Can prevent falling forward.

  In addition, since the forearm support arms are in the shape of a letter C at the forward-tilt prevention position, even if the user supports the forearm support arm entirely on the forearm support arm, it is stable without imposing a heavy burden on the shoulder joint or the like. The body can be supported and a C-shaped space is formed in front of the user, so that the user is not oppressed.

  Moreover, because the forearm is supported by the forearm support arm from the elbow to the wrist, even if it is used for a long time, the pressure on the forearm is distributed from the elbow to the wrist depending on the weight of the user, causing poor blood circulation locally. This prevents accidents that cause necrosis of skin tissue.
