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 a side fence becomes a hindrance when the patient gets on and off the bed, and therefore, the side fence is removed, folded, and stored so as to open the bedside according to the function of the side fence.

[0003]

[Problems to be Solved by the Invention] However, when the side fence is removed from the bedside, there is nothing to grasp to assist the patient in moving the body position, and when the patient stands up, the patient is in bed. Since he has no choice but to support his body by holding his hands on the side parts of his, etc., 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 has a support position switch for mounting a support on a side frame of a bed, and rotating and fixing a holding member to a predetermined position on the support. It is configured to be attached via a mechanism. The support position switching mechanism allows the connecting shaft fixed to the support column to enter the gripping member to rotate the gripping member, attach a fixed gear to the tip of the connecting shaft, and attach a pair of stoppers to the gripping member. The distal end portion is provided so as to elastically contact and lock with the teeth of the fixed gear, and a fan-shaped cam member is rotatably interposed between these stoppers by an operation lever.

[0005]

In order to fix the gripping member to the column, the operation lever is operated to rotate the fan-shaped cam member, and the tips of the pair of stoppers are elastically elastically attached to the teeth of the fixed gear at an equal angle. Make sure that they come into contact and lock. When the gripping member is rotated to bring it to the desired position, the operating lever is operated to rotate the fan-shaped cam member so that the tip of the stopper on one side is disengaged from the teeth of the fixed gear. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an assistance bar according to the present invention will be described below with reference to the accompanying drawings by way of an embodiment. In FIG. 1 and FIG. 2, reference numeral 1 indicates an assisting bar. The assisting bar 1 has a support 4 attached to a side frame 3 of a bed 2, and a support bar 5 as a holding member is attached to the support 4 at a predetermined position. It is configured to be attached via a support position switching mechanism 6 that is rotated and fixed.

As shown in FIG. 3, the support position switching mechanism 6 allows the gripping bar 5 to rotate by allowing the connecting shaft 7 fixed to the column 4 to enter the gripping bar 5, and the tip end portion of the connecting shaft 7 can be rotated. A fixed gear 8 is attached to the grip bar 5, and a pair of stoppers 9 are attached to the grip bar 5.
Is provided by a compression spring member 10 so that the tip end thereof elastically abuts and locks against the teeth of the fixed gear 8.
A fan-shaped cam member 11 is rotatably interposed by an operating lever 12.

According to the assistance bar 1 according to the present invention, in order to fix the gripping bar 5 to the support column 4, the operation lever 12 is operated to rotate the fan-shaped cam member 11 to move the pair of stoppers 9. The tip is elastically abutted and locked to the teeth of the fixed gear 8 at an equal angle (see FIG. 3). When turning the grip bar 5 to bring it to a desired position, the operating lever 1
2 is operated to rotate the fan-shaped cam member 11, and the stopper 9 on one side is disengaged from the teeth of the fixed gear 8 at the tip. Then, the grip bar 5 can rotate in the clockwise and counterclockwise directions (see FIGS. 4 and 5). When the grip bar 5 is brought to a desired position, the operation lever 12 is operated. By moving to a fixed position,
The grip bar 5 can be fixed. As a result, the grip bar 5 comes to a position where the supine patient can reach, so that the grip bar 5 can be easily gripped, and the patient can easily move his / her body position. When the floor of the bed 2 is raised, the grip bar 5
The grip bar 5 may be rotated so as to move to the side frame 3 side so as not to hit the mattress. Further, when the patient sits up on the bed 2 side and stands up from the bed 2 side, the grip bar 5 can be easily assisted.

[0009]

As described above, according to the present invention, the patient is
In the supine state, the grasping member can be grasped, the body position can be easily moved, and it is possible to get out of the bed, stand up at the bedside, and stand up from the bedside. Further, since the structure is simple, there is an advantage that there is no problem in cost.
