Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a foldable bed which is mainly installed in a toilet booth for a physically handicapped person, a dressing room of a nursing facility, and the like, and particularly uses a foldable bed for a wheelchair user or an assistant or for changing diapers. The present invention relates to a handrail and a storeroom for improving user's convenience.

[0002]

2. Description of the Related Art A conventional foldable bed merely provides a floor for lying down on a body, for example, a handrail for holding a body when a wheelchair user transfers from a wheelchair to the floor. And did not provide a place to store luggage.

[0003]

For this reason, for example, a wheelchair user who is half-paralyzed transfers to a floor from a wheelchair in an unstable state in which he can only hold his body with one leg when using a folding bed. I had to. In addition, when transferring, the user needs to take out only the necessary items and place the luggage away from the folding bed or move the luggage once on the floor and transfer while moving the luggage. Action had to be performed. In addition, toilet booths for the disabled with such foldable beds are generally small,
Often there is no place to put luggage. For this reason, the user puts the luggage on the washbasin, but in many cases, the toilet booth for the handicapped is equipped with automatic flushing, and the luggage often becomes flooded. In addition, since the caregiver keeps the body in a different place such as a towel for wiping, the work is often difficult. In order to solve the above-mentioned problems, the present invention provides a folding bed provided with a flip-up handrail and a storage.

[0004]

According to a first aspect of the present invention, a front floor and a rear floor are provided, and the front and rear floors are pivotally connected so as to be freely and horizontally storable. A torsion bar that elastically urges in a direction to be folded into a stowed state is disposed along a pivot axis of the joint at a part of a joint for swingably pivoting, and is located at a rear position. A foldable bed having a fixed support member and pivotably attached to the fixed support member so that the rear end side of the rear floor body can swing up and down, wherein the foldable bed rotates parallel to a swing axis of the joint. A foldable bed provided with a flip-up handrail that rotates about an axis.

According to the present invention, since a flip-up type handrail is provided which rotates about a rotation axis parallel to the swing axis of the folding bed, the flip-up type handrail is used when the flip-up type handrail is not used. Since the flip-up handrail can be folded in the same direction as the folding bed, a space such as a toilet booth for the handicapped can be effectively used.

According to a second aspect of the present invention, the handrail portion of the flip-up handrail is disposed on the side of the bed along the long side direction of the folding bed, and the rotation axis of the flip-up handrail is fixed to the floor. It is fixed to the floor via members.

According to the present invention, the flip-up handrail can be installed at a required position according to the situation of the installation place where the folding bed is installed.

According to a third aspect of the present invention, the handrail portion of the flip-up handrail is arranged on the side of the bed along the long side direction of the folding bed, and the rotary shaft of the flip-up handrail is fixed to a wall. It is fixed to the wall via a member.

According to the present invention, the flip-up handrail can be installed at a necessary position according to the situation of the installation place where the folding bed is installed.

According to a fourth aspect of the present invention, the handrail portion of the flip-up handrail is disposed on a lateral side of the bed along a longitudinal direction of the foldable bed, and a rotation axis of the flip-up handrail is a fixed member. The foldable bed according to claim 1, wherein the foldable bed is fixed to the fixed support member via a second member.

According to the present invention, since the flip-up handrail is fixed to the fixed support member, there is no need to perform a work for installing the flip-up handrail.

According to a fifth aspect of the present invention, the position of the handrail is such that the lower end surface thereof is at least 200 mm from the upper end surface of the floor and the diameter or width of the handrail is at most 75 mm.

According to the present invention, by setting the position of the handrail at 200 mm or more from the floor, even if a user falls off the floor during use, the user may catch his / her neck on the handrail and suffocate. Nothing. In addition, the foldable bed is usually installed near the wall, and the gap between the wall on the long side of the foldable bed and the floor of the foldable bed is designed so that the user does not get stuck in the gap during use. The gap is 100 mm. At this time, when installing a handrail on the wall side, the width of the handrail needs to be 75 mm or less so as not to pinch a finger between the handrail and the wall.

According to a sixth aspect of the present invention, the upper surface of the handrail is flat.

According to the present invention, by making the upper surface flat, even a user who cannot grasp the handrail can hold his / her body with the handrail.

According to a sixth aspect of the present invention, a storage is installed on the handrail.

According to the present invention, since the storeroom is installed on the handrail, the user can place luggage on the handrail before work, and the work can be performed easily.
Further, since the luggage is always placed at the position of the handrail, even when the user who has moved on the floor takes out the tools in the luggage, the luggage is conveniently located nearby.

According to another aspect of the present invention, there is provided a front floor body and a rear floor body, wherein the front floor body and the rear floor body are pivotably connected to each other so as to be horizontally and freely stored, and are also folded from the horizontal deployment state to the mountain-folding storage state. A torsion bar that is elastically biased to a part of a joint for swingably pivoting, is disposed along the swing axis of the joint, and includes a fixed support member at a rear position; A folding bed in which the rear end of the rear floor is swingable up and down and pivotally attached to the fixed support member, wherein a storage is installed below the front floor or the rear floor. Provide tatami beds.

According to the present invention, since the storage room is installed below the floor of the folding bed, the storage room can be provided even if there is no space for installing a handrail with a storage room.
