In the support position switching mechanism 6, a fixed gear 8 is attached to the tip of the connecting shaft 7 fixed to the column 4, and a pair of stoppers 9 are abutted on the teeth of the fixed gear 8 with the pair of stoppers 9 on the grip bar 5. A fan-shaped cam member 11 is rotatably interposed between the stoppers 9 by the operation lever 12 so as to be locked. [Effect] The patient can easily move his / her body posture in the supine state, and can get out of the bed, sit up at the bedside, and stand up from the bedside.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an assistance bar.

[0002]

[Prior 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 were a hindrance when the patient got in and out of the bed, and therefore the side fences were removed, folded, and stored to open the bedside according to the function of the side fence. ..

[0003]

[Problems to be solved by the device]

 However, when the side fence is removed from the bedside, there is nothing to grasp to assist the patient when moving from the body position, and when the patient stands up, the patient should not touch the side part of the bed. For this reason, the body must support the body, and the posture and burden have been forced. The present invention has been made in view of such problems.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a structure in which a support is attached to a side frame of a bed, and the support member is attached to the support via a supporting position switching mechanism for rotating and fixing a gripping member to a predetermined position. It is a thing. The support position switching mechanism allows the gripping member to rotate by inserting the connecting shaft fixed to the support into the gripping member, attaches a fixed gear to the tip of the connecting shaft, and attaches a pair of gripping members to the gripping member. A stopper is provided so that the tip end portion thereof elastically abuts and locks against the teeth of the fixed gear, and a fan-shaped cam member is rotatably interposed between these stoppers by an operating lever.

[0005]

[Operation] 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. ..

[0006]

【Example】

 Next, the assistance bar according to the present invention will be described below with reference to the accompanying drawings, with reference to an embodiment. In FIGS. 1 and 2, reference numeral 1 denotes an assisting bar. The assisting bar 1 has a support 4 attached to a side frame 3 of a bed 2, and a holding bar 5 as a holding member is attached to the support 4 at a predetermined position. It is configured to be mounted via a support position switching mechanism 6 which is rotated and fixed to.

As shown in FIG. 3, the support position switching mechanism 6 allows the connecting shaft 7 fixed to the support column 4 to enter the grip bar 5 so that the grip bar 5 is rotatable, and the tip of the connecting shaft 7 is rotated. A fixed gear 8 is attached to the gripping bar 5, and a pair of stoppers 9 are provided on the gripping bar 5 by a compression spring member 10 so that the front ends thereof elastically abut and lock with the teeth of the fixed gear 8. The fan-shaped cam member 11 is rotatably interposed by the operation 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 and the pair of stoppers 9 are provided. The tip of the blade is elastically abutted and locked to the teeth of the fixed gear 8 at an equal angle (see FIG. 3). When the grip bar 5 is rotated to bring it to a desired position, the operation lever 12 is operated to rotate the fan-shaped cam member 11, and the stopper 9 on one side is moved from the teeth of the fixed gear 8 to the tip end thereof. Let go. Then, the grip bar 5 can rotate in the clockwise direction and the counterclockwise direction (see FIGS. 4 and 5), and when the grip bar 5 is brought to a desired position, the operation lever 12 is operated. Then, the grip bar 5 can be fixed by moving to the fixed position. As a result, the grip bar 5 comes to a position where the patient in a supine position can reach, so that the grip bar 5 can be easily gripped, and the patient can easily move his / her body position. Further, when the floor of the bed 2 is raised, the grip bar 5 may be rotated and moved to the side frame 3 side so that the grip bar 5 does not hit the mattress. Further, when the patient sits up on the bed 2 side and rises up from the bed 2 side, the grip bar 5 can be easily assisted.

[0009]

[Effect of the device]

 As described above, according to the present invention, the patient can grasp the grasping member in the supine state, can easily move his / her body position, get off the bed and sit up at the bedside, It is possible to stand up from. Furthermore, since the structure is simple, there is an advantage that there is no problem in cost.
