Description of the Related Art When a physically handicapped person, such as a sick person or a physically handicapped person, gets up and down on a bed, the side rails and the headboard provided on the bed are used as clues. It is common to use. However, since the side rails and the headboard attached to these beds are fixed to the bed and their positions cannot be adjusted, it is inconvenient for getting up and down on the bed. In order to solve this inconvenience, it is necessary to provide a laterally rotatable assistance frame at the side end of a detachable side rail body provided at an appropriate position on the bed and to prevent the rotation thereof. There has been proposed an assisting device provided with a lock mechanism capable of performing the following (see Japanese Utility Model Publication No. 4-50028). Since this assistance device can rotate and fix the assistance frame at an appropriate angle, it can be used as a clue when going up and down on the bed, and at the same time, the side rail and the assistance frame can be used simultaneously. Although it is practically convenient because it can be removed, the side rail can be removed leaving only this assistance frame part because the rotating assistance frame part is provided integrally with the side rail. In some cases, the siderails could get in the way. Also, Write gap between the side rail and the rotatable care for frame portion is also good usability, but care for frame parts of the revolvable the end of the conventional ones siderails Because they were attached, there was no space between them. Therefore, according to the present invention, a fixed frame corresponding to the side rail is provided on a side portion of the bed, and the bed is rotated at a distance from the fixed frame. An object of the present invention is to provide a bed assisting device which can provide an assisting frame of a type and can remove both of them at the same time, or can remove only a fixed type frame. [0005] In order to solve the above problems, the present invention employs the following configuration. That is, the bed side frame device according to the present invention comprises a plurality of pillars, a horizontal frame connecting upper ends of the plurality of pillars, and a support arm extending in the longitudinal direction of the bed from the pillar or the horizontal frame.
A detachable base frame attached to the bed such that the horizontal frame is lower than the upper surface of the bed mattress, and a detachable base frame attached to the side frame of the bed. A detachable insertion-side frame attached to the base frame by inserting a leg portion into an insertion hole provided therein, and a support arm distal end of the base frame at a position away from the insertion side frame is turned in a horizontal plane. A rotating handrail portion provided with a lock device that is movably supported and can be fixed at an arbitrary rotating position. The pivoting handrail is rotated to an appropriate position and fixed by a lock device, so that it can be used as a clue for rising and falling. Detachable insertion side frame,
A rotatable handrail portion rotatable in a horizontal plane is mounted on a common base frame, and when unnecessary, the side frame and the rotatable handrail portion can be integrally removed together with the base frame. Further, when the side frame is obstructed by climbing or descending, it is convenient because only the side frame can be removed while leaving the rotating handrail portion. If an appropriate space is provided between the side frame and the rotating handrail, the space can be used, for example, when picking up an article on a side table beside a bed. . An embodiment of the present invention will be specifically described below with reference to the drawings. In this assisting device 1, an insertion side frame 3 detachably attached to a side portion of a bed 2 and a rotating handrail portion 4 rotatable in a horizontal plane are mounted on a common base frame 5. By rotating the handrail unit 4 at an appropriate angle and fixing it, a person using a bed such as a physically handicapped can easily get up, stand up on the floor, or walk by grasping it. Can be done. The base frame 5 of the assistance device 1 has two support columns 5
a, 5b, and a horizontal horizontal frame 6 for connecting the both columns is integrally provided at the upper ends of these columns. An obliquely upward support arm 7 extending from the support 5b along the longitudinal direction of the bed is fixed to one support 5b. The side frame 9 of the bed 2 is provided with a plurality of fitting holes 9a,... Along the longitudinal direction, and a shaft provided at the lower part of the columns 5a, 5b of the base frame 5 is fitted with these fitting holes. The base frame is attached to the bed by inserting it into the bed. The shaft of one of the two columns 5b is eccentrically mounted on the column so as to be eccentric with respect to the axis of the column. By rotating the support around the axis of the column by 180 degrees using the fixed handle 10 in a state fitted to the bed 9a, the shaft side is pressed against the inner peripheral surface of the mounting hole 9a of the bed frame, and the base frame 5 is put on the bed. It can be fixed. If the fixed handle 10 loose Melle the base frame 5 can be removed from the bed. When the base frame 5 is fixed to the bed, the horizontal frame 6 is positioned below the upper surface of the mattress M laid on the bed. The insertion holes 11, 1 are provided above the columns 5a, 5b.
1 is provided, and the insertion side frame 3 is attached to the base frame 5 by inserting mounting shafts 12, 12 provided on the legs of the insertion side frame 3. At the end of the support arm 7 projecting from the base frame 5, a chrysanthemum seat receiving portion 15 having a sawtooth-shaped tooth row 15a on its upper surface is fixed. A small vertical fitting shaft 16 is integrally formed. Inside the chrysanthemum seat 15, a stopper portion 18 having a vertical through hole 17 at the center is integrally formed, and a concave portion 19 is formed below the stopper portion. A shaft 20 having a screw portion 20a at the lower end is inserted into the through hole 17, the upper end of the shaft protrudes above the fitting shaft portion 16, and a flange 21 is attached near the upper end. . The lower end of the shaft 20 projects into the recess 19, and a nut 22 is screwed into this portion. On the other hand, the rotating handrail portion 4 has a handrail body 4a obtained by bending a hollow pipe in a loop shape and a row of teeth which is fixed to a joint portion of the pipe and meshes with a row of teeth 15a of the chrysanthemum seat receiving section on the lower surface. It consists of a cylindrical base 25 having 25a. The rotating handrail portion 4 is attached to the base frame 5 so as to be rotatable around the fitting shaft portion by fitting the cylindrical base portion 25 to the fitting shaft portion 16 integral with the chrysanthemum seat. A lock device 30 is provided on the outer peripheral surface of the base 25.
The attachment plate 32 is fixed, and a vertically long slit 33 is formed in the base side wall of this portion. A pivot member 35 having a distal end inserted into the base 25 through the slit 33 is attached to the attachment plate 32 with a pin P. The rear portion of the rotating member 35 is a key-shaped engaging portion 35a that is slightly bent upward. Further, on the upper side of the rotating member 35, an engaging portion 35 of the rotating member is provided.
