[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assisting device that functions as an assist when getting on and off a bed.

[0002]

2. Description of the Related Art It is well known that a side fence provided on a side frame of a bed generally has a function of supporting a patient. Such side fences become a hindrance when the patient gets on and off the bed, and therefore, depending on the function of the side fence, it can be removed, folded or stored to open the bedside. I was trying to do it.

[0003]

However, when the bedside is open, there is nothing to grasp to assist the patient in moving the body, and when the patient stands up, the patient is in bed. Since he has no choice but to support his body with his hands on the side parts, he has been forced into an unreasonable posture and burden. The present invention has been made in view of such problems.

[0004]

In order to solve the above-mentioned problems, the present invention provides a pair of mounting holes in a side frame of a bed, a base for holding a tightening member to be fitted into the mounting holes, and a base. A shaft member having a polygonal cross section that is erected at the center, and a hollow pillar having an inner polygonal surface into which the shaft member can be fitted,
The holding frame member integrally provided on the hollow support, and a fixing holding member for tightening and fixing the hollow support when the hollow support is attached to the shaft member, the tightening member,
Hollow cylinder member and this hollow cylinder with the tip side threaded
Tightening bolt inserted into the member and this fastening bolt
A hollow cylindrical member and a nut.
It is characterized in that the surface facing the door is an inclined surface .

[0005]

[Function] The tightening member is inserted into the pair of mounting holes on the side frame, and the base is tightened and fixed. That is, as the tightening bolt is screwed in, the hollow columnar member and the nut are pressed against each other via the inclined surfaces, and a lateral displacement force is generated in the hollow columnar member to press the inner surface of the mounting hole. Therefore, the base is attached to the side frame without rattling. Next, the hollow column is attached to the shaft member at the center of the base. Each corner of the shaft member is locked along the corner of the inner wall of the hollow column. Then, the fixed support member is operated to tighten and fix the hollow column to the shaft member. The fixed holding member can be loosened and the grip frame member can be rotated. At this time, the corners of the shaft and the hollow pillars that are locked to the corners of the shaft are
It moves while being locked to the corner of the adjacent shaft member and further to the adjacent corner. For this reason, the grip frame member rotates and moves in steps in a predetermined rotation angle unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an assisting tool according to the present invention will be described below with reference to the accompanying drawings with reference to an embodiment. In FIG. 1, reference numeral 1 indicates an assisting tool, and the assisting tool 1 includes a pair of mounting holes 3 in a side frame 2 of a bed, and a tightening member 4 that is fitted into the mounting holes 3 and is fixed by tightening.
A base 5 holding the base 5, a shaft member 6 standing in the center of the base 5 and having a polygonal cross section, an inner polygonal hollow column 7 for housing the shaft member 6, and a hollow column 7 integrally provided The holding frame member 8 and the hollow strut 7 are substantially constituted by a fixed holding member for fastening the hollow strut 7 to the shaft member 6 when the shaft member 6 is inserted, that is, an operation knob 9.

As shown in FIG. 2, the tightening member 4 includes a hollow columnar member 10, a nut 11, and a hollow columnar member 1.
It is configured such that the tightening bolt 12 is screwed into the nut 11 by inserting it into the nut 0. The hollow columnar member 10 and the nut 11 have inclined surfaces 13 and 14 facing each other.

The shaft member 6 is a hexagonal shaft, and the inner surface of the hollow column 7 is dodecagonal. The diagonal lines L on the inner surfaces of the shaft member 6 and the hollow column 7 have the same dimensions (see FIG. 3).

The gripping frame member 8 is composed of a pipe whose end portion is bent into an arc shape, and includes a lower pipe 15 and an upper pipe 1.
6 and 6 are joined to the hollow column 7 in parallel and in the horizontal direction. Further, the lower pipe 15 and the upper pipe 16 are joined by a vertical pipe 17 at an intermediate portion.

As described above, in the assistance tool 1 according to the present invention,
The fastening member 4 is inserted into the pair of mounting holes 3 on the side frame 2, and the base 5 is fastened and fixed. That is, when the tightening bolt 12 is screwed in, the hollow columnar member 10
The nut 11 and the nut 11 are pressed against each other via the inclined surfaces 13 and 14 to generate a lateral displacement force on the hollow cylindrical member 10 and press the inner surface of the mounting hole 3. Therefore, the base 5 is attached to the side frame 2 without rattling.

Next, the hollow column 7 is attached to the shaft member 6 at the center of the base 5. Each corner of the shaft member 6 is locked along the corner of the inner wall of the hollow column 7. Then, as shown in FIG. 4, the operation knob 9 is operated to tighten and fix the hollow column 7 to the shaft member 6. When the operation knob 9 is loosened, the grip frame member 8 can be rotated. At this time, the shaft member 6 and the corner portion of the hollow column 7 that is locked to the corner portion of the shaft member 6 move while being locked to the corner portion of the adjacent shaft member 6 and further to the adjacent corner portion. . Therefore, the hollow support column 7 can be rotationally moved stepwise in units of a rotation angle of 30 °, and the grip frame member 8 can be moved to a desired position. In addition, if the grip frame member 8 is fixed along the side frame 2, it can function as a side fence.

[0012]

EFFECTS OF THE INVENTION According to the present invention, a patient can easily move his / her body by grasping the gripping frame member as a clue, get down from the bed, sit up at the bedside, and stand up from the bedside. Is possible. As described above, as described above, the configuration of the assisting tool according to the present invention is simple, and there is an advantage in that there is no problem in cost.
