Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an assisting device that also serves as a side rail for beds in homes, hospitals, and the like.

(Prior art) When a patient, a physically disabled person, an elderly person, or other physically weak person gets up on the bed or gets on and off the bed, they should use side rails, headboards, etc. as handholds. They also use special assistance devices installed in their beds. (For the latter, see Utility Model Application Publication No. 63-109130, for example.) (Problem to be solved by the invention) When using side rails or headboards, it is difficult to always use them as appropriate cues for each movement of the patient, etc. Moreover, dedicated assistance devices have the problem that they get in the way when not in use.

The present invention aims to solve such problems.

(Means for Solving the Problems) The means for solving the above-mentioned problems will be explained with reference to the drawings corresponding to the embodiments. Detachable side rail body 1
An assisting frame 5 is provided at the side end portion of the assisting frame 5 so as to be rotatable in the lateral direction, and a locking mechanism 6 is provided which can freely prevent rotation of the assisting frame 5.

In the above configuration, the side rail main body 1 is
The lower end of the support column 2 can be inserted into and removed from a fitting cylinder 4 provided on the floor support frame 3 of the bed, so that it can be configured to be detachable. Further, a gripping slope portion 28 can be formed on the upper frame member of the assistance frame portion 5. Further, the lock mechanism 6 can be configured to be able to hold the assistance frame 5 at least in a position coplanar with the side rail main body 1 and in a position orthogonal to the side rail main body 1.

(Function) When the patient or the like lies supine on the floor of the bed, the assistance frame 5 is held in the same plane as the side rail main body 1 by the lock mechanism 6. In this state, the assistance frame 5 does not protrude in the lateral direction of the bed, so it does not interfere with traffic or the like. The patient or the like can easily get up from the floor by grasping the assistance frame 5 and using it as a handhold.

When a patient, etc. gets off the floor of the bed or gets on the bed, the locking mechanism 6 is operated to make the assistance frame 5 rotatable, so that it protrudes laterally from the side rail body 1. At this point, the lock mechanism 6 is operated again to maintain this state. In such a state, the space occupied by the assistance frame 5 in the above-mentioned state is vacant, and the assistance frame 5 is disposed in the direction of movement of the body during the movement of getting on and off. You can use it as a proper handhold to get on and off the vehicle.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

Figures 1a and 1b are explanatory external views showing the overall configuration and operation of the device of the present invention. Reference numeral 1 is a side rail body, and this side rail body 1 has a pair of left and right support columns 2 with lower ends attached to the bed. floor support frame 3
It is configured to be detachable from the side of the bed so that it can be inserted into and removed from the fitting cylinder portion 4 provided in the bed. In this way, the pillar part 2
In the configuration in which the lower end of the is fitted into the fitting cylinder part 4 to be in the attached state, in order to prevent it from easily coming off or shaking and becoming unstable in this attached state, Provide an appropriate tightening mechanism. As such a tightening mechanism, for example, a mechanism such as that disclosed in Japanese Utility Model Application Publication No. 62-85168 can be applied.

Thus, the assistance frame 5 is provided at the side end of the side rail main body 1 so as to be rotatable in the lateral direction, and
A lock mechanism 6 is provided which can freely prevent rotation of the assistance frame 5.

In the configuration shown in FIG. 2a, an operating shaft 8 which also serves as support is rotatably supported on the side end member, and this operating shaft 8 is rotatably operated by a grip 9. A cylindrical body 7 provided at one end of the assistance frame 5 is rotatably supported.
Further, a first engaging body 11 having a first engaging surface 10 such as a radial protrusion is provided on the lower surface of the cylindrical body 7, and the side end member has the first engaging surface 10 formed on the upper surface thereof. A second engaging body 13 having a second engaging surface 12 corresponding to the mating surface 10 is provided, and this second engaging body 1
3 is provided with a female threaded portion 15 that is screwed into the threaded portion 14 formed on the operating shaft 8.

In the above configuration, when the operating shaft 8 is rotated in a predetermined direction by the grip 9, the threaded portions 14, 15
As a result, the second engaging body 13 moves upward, and the second engaging surface 12 on the upper surface thereof engages with the first engaging surface 10 of the first engaging body 11, so that the cylinder body 7 can be operated. Rotation around the shaft 8 becomes impossible, and conversely, when these engaging surfaces 10 and 12 are not engaged, the cylinder body 7 can freely rotate around the operating shaft 8, and the assistance frame The part 5 can be rotated laterally. In the lock mechanism 6 described above, the assistance frame 5 can be fixed at an appropriate rotation angle allowed by the engagement surfaces 10 and 12.

Next, the configuration of FIGS. 2b, c, and d is as shown in FIG.
The lock mechanism 6 is similar in that it is supported by a cylinder 7 on the side end member of the side rail main body 1 so as to be rotatable in the lateral direction, but the lock mechanism 6 is different as follows.

First, in Figure 2b, unlike the configuration in Figure 2a,
The second engaging body 13 of the side end member is not moved;
The first engaging body 11 is configured to move together with the cylinder 7, and the first engaging body 11 has an inclined cam surface 17 formed at the lower part of the operating shaft 16 that passes through the center of the second engaging body 13. An actuating body 18 is provided, and by pressing and moving the inclined cam surface 17 with a tightening screw 19, the first engaging body 11 is moved via the operating shaft 16.

Next, in FIG. 2c, unlike the configuration in FIG. 2a, the second engaging body 13 of the side end member is installed at the top with the second engaging surface 12 facing downward, and the A first engagement surface 10 is provided on the upper part of the cylindrical body 7 of the frame part 5.
The first engaging body 11 is installed with the cylindrical body 7 facing upward, and the operating shaft 20 is provided at the bottom of the cylinder body 7.
An operating cam 21 for vertically moving the operating shaft 20 is provided on the side end member, and the operating cam 21 is connected to the operating lever 22.

At the same time, the first engaging body 11 is moved up and down to operate and release the lock.

Next, in the configuration of FIG. 2 d, unlike the above-mentioned configuration, the engaging body with the engaging surface formed is not used, and the actuating shaft 20 provided on the lower side of the cylinder 7 is connected to the support provided on the side end member. By penetrating the center hole 24 of the body 23 and the center hole 26 of the actuating body 25, and moving the actuating body 25 laterally by a tightening mechanism using a wing nut 27 to shift the center holes 24 and 26, The actuating shaft 20 is pressed against the inner walls of these center holes 24 and 26 to prevent rotation of the actuating shaft 20 and rotation of the cylindrical body 7, resulting in a locked state.

In the lock mechanism 6 described above, the assistance frame 5
can be held at a substantially appropriate angle with respect to the side rail body 1, but in addition, at least at a position coplanar with the side rail body 1 and at a position perpendicular to the side rail body 1. It can also be configured to be able to be held.

The shape of the assistance frame 5 may be determined as appropriate;
As shown in the figure, there is a gripping slope 28 on the upper frame member.
It is possible to form an appropriate part that is easy to grip, such as forming a .

(Effects of the Invention) As described above, the present invention provides an assistance frame that is used as a handhold when a patient, etc. gets up on the bed or gets on and off the bed, at the side end of the side rail body. By holding this assistance frame at an appropriate angle with respect to the side rail body, it can be used as a suitable handhold at all times, and when not in use, it can be used as a conventional side rail. Since it has the same form as a rail, it has the effect of not getting in the way.
