Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an auxiliary mechanism that allows a physically handicapped person such as a patient or the elderly to easily get on and off a bed. be.

[Conventional technology]

As a conventional getting on/off assistance mechanism for a bed, there is one shown in FIG. 5, for example.

This auxiliary mechanism a has a gripping member C erected on a base, and a person d such as a patient to be assisted gets on and off the bed e while grasping the gripping member C.

[Problems to be solved by the present invention]

As mentioned above, the conventional auxiliary mechanism a becomes a nuisance when not in use, and if you try to put it away, you have to secure a separate storage space for it, which poses the problem of poor space efficiency. .

The present invention aims to solve such problems.

[Means for Solving the Problems] The configuration of the present invention will be explained based on FIGS. 1 to 4, which correspond to embodiments.

First, the getting on/off assisting mechanism 1 for a bed according to claim 1
This is a shelf member in which a fitting hole 4 is provided in the vertical direction on the lateral side of the floor support frame 3 of the bed 2, and a fitting rod 5 corresponding to the fitting hole 4 is provided at one end of the lower side to protrude downward. A support leg portion 7 is configured at the other end of the lower side of the bed 2, and the shelf member 6 is fitted at a desired opening angle α from the head/foot direction XX of the bed 2 and the head/foot direction XX. The mating rod 5 is inserted into and removed from the fitting hole 4 of the floor support frame 3 so that it can be freely erected, and a rotation prevention mechanism 8 is provided to prevent the shelf member 6 from rotating in this erected state. A grip portion 9 is formed on the upper side of 6.

Next, the mechanism 1 described in item 2 has a support leg portion 10 provided below the fitting rod 5 described in item 1.

The mechanism l described in item 3 allows the rotation prevention mechanism 8 described in item 1 to be set at a desired opening angle α from the head and foot direction XX when the shelf member 6 is located in the head and foot direction XX of the bed 2. The fitting hole 4 is formed so that the fitting rod 5 can be freely inserted into and removed from the fitting hole 4 only when the fitting rod 5 is in the position.

In the mechanism 1 described in item 4, the rotation prevention mechanism 8 described in item 1 can be freely inserted into and removed from the female threaded portion 1) provided in the fitting hole 4, and the fitting rod 5 is inserted into and removed from the fitting hole 4. The female threaded part 1 has an elastic tightening member 13 forming a through hole 12 that can be freely penetrated, and a male threaded part 15 that forms a through hole 14 that can be freely penetrated by the fitting rod 5 and is screwed into the female threaded part 1). ) and a tightening screw 17 formed with a pressing portion 16 corresponding to the elastic tightening member 13 when screwed together with the elastic tightening member 13.

The mechanism 1 described in item 5 has the fitting hole 4 in the head and foot direction of the bed 2.
-X is provided in multiple rows. Further, the mechanism 1 described in item 6 has a plurality of rows of fitting holes 4 arranged in the head/foot direction XX of the bed 2, and a plurality of rows of fitting rods 5 corresponding to these fitting holes 4. It is something.

[For production]

With the shelf member 6 set at a desired angle α from the head/foot direction XX of the bed 2, for example in the lateral direction of the bed 2, a fitting rod 5 protruding downward from one end of the lower side of the shelf member 6 is supported on the floor. When the shelf member 6 is inserted into the fitting hole 4 provided vertically in the horizontal side of the frame 3 and the shelf member 6 is supported by its supporting legs 7 to stand up, the shelf member 6 can be rotated in this state. Since the shelf member 6 cannot be rotated by the rotation prevention mechanism 8, the shelf member 6 does not move even if it is grabbed by the shelf member 6 and is stable.

Furthermore, since a gripping portion 9 is formed on the upper side of the shelf member 6, it is easy to grasp the shelf member 6. Therefore, when the person to be assisted 19, such as a patient or the elderly, gets on and off the bed 2, the person 19 to be assisted can grasp the shelf member 6. Since the user can get on and off the vehicle while grasping the portion 9, such getting on and off operations can be made easier.

When the mechanism 1 is not in use, it protrudes from the side of the bed 2 and is a nuisance, and it may be necessary to put it away. After pulling out the fitting rod 5 from the fitting hole 4 and releasing the fitting engagement, the shelf member 6 is moved to the bed 2.
With the head and foot direction XX, insert the fitting rod 5 into the fitting hole 4 again.
If the shelf member 6 is inserted into the bed 2, the shelf member 6 will not protrude to the side of the bed 2, and therefore a space-efficient storage state can be realized. Further, even in such a state, the shelf member 6 does not move and is stable due to the rotation prevention mechanism 8, so that it functions as a side fence to prevent accidents such as falling of the person to be assisted 19 on the bed 2. Can be used together.

〔Example〕

As in the embodiment shown in FIG.
For example, if two shelf members 6 are arranged side by side, each shelf member 6 can be grasped with both hands, making it possible to realize a more effective getting on/off assistance function. By erecting them on both sides of the bed 2, the bed 2 can be used as a normal bed 2 having side rails on both sides.

If the shelf member 6 is constructed of a pipe-like structure as shown in FIG. 2 and it is difficult to support the shelf member 6 with only the supporting legs 7, the fitting hole 4 may not be a through hole. When the bottom of the fitting hole 4, that is, the floor support frame 3 supports the fitting rod 5, or the mechanical strength of the floor support frame 3 is insufficient, the fitting hole 4 is made into a through hole. At the same time, the fitting rod 5 may be made longer to form the support leg portion 1O on the lower side thereof.

In addition, if there is a concern about the mechanical strength of only the pair of fitting rods 5 and support legs 7, additional fitting holes 4 may be added in the head/foot direction free fitting rod 5';
5", . . ., the shelf member 6 can be stably supported.

The rotation prevention mechanism 8 is, for example, as shown in FIG.
is a square hole, and the fitting rod 5 is a square rod. It is possible to freely insert and remove the fitting rod 5 only in the state located at the angle α, or to configure the fitting rod 5 with a flat square rod as shown in FIG. In one of these fitting spaces, for example, the fitting space 20', the shelf member 6 is located in the head/foot direction XX of the bed 2. In this state, the flat square rod fitting rod 5 can be freely inserted and removed, and the other fitting space 2
0 may be configured such that it can be freely inserted and removed in a state where the shelf member 6 is located at a desired opening angle α from the head-to-foot direction XX of the bed 2.

In addition, the rotation prevention mechanism 8 may have a configuration that utilizes the frictional force of the elastic tightening member 13, as shown in FIG. 4, for example. In this configuration, the fitting hole 4 is formed as a round hole, and a female threaded portion 1) is formed inside the fitting hole 4. The diameter of the lower side of the fitting hole 4 is made smaller than that of the member 13, and the member 13 is inserted into the hole from above the fitting hole 4 into the through hole 1.
If you drop it so that 2 is in the vertical direction, the hole diameter on the bottom side of the fitting hole 4 is smaller than this as mentioned above, so it will not fall under 7L 4 and will stay in the hole 4. be able to.

When the tightening screw 17 is screwed in from above the hole 4, the tightening screw 17 is also formed with a through hole 14, and each of the through holes 12 and 14 is configured to allow the fitting rod 5 to pass through it. Therefore, the fitting rod 5 can be inserted into the through hole 12.14.

If the tightening screw 17 is loosened in this state, the pressing part 1
6 does not apply force to the member 13, so the fitting rod 5 of the member 13
The frictional force exerted on the inner surface of the fitting hole 4 is small, so the fitting rod 5 can freely pivot relative to the hole 4.

Next, when the tightening screw 17 is strongly tightened, the pressing part 16
compresses the member 13 in the vertical direction, and as a result, the member 13 expands in the lateral direction and exerts a strong frictional force against the fitting rod 5 and the inner surface of the fitting hole 4. can be rotated.

Therefore, in such a configuration, the fitting rod 5 is attached to the tightening screw 1.
By simply operating 7, the fitting rod 5 can be made pivotable or non-swivelable as appropriate, so it is of course possible to make the shelf member 6 non-swivelable even when it is located in the head/foot direction XX of the bed 2. Moreover, the desired angle α from the head-to-foot direction XX can be set to the optimum angle according to the needs at the time.

The elastic tightening member 13 is made of rubber or the like, and its shape may be any suitable shape such as a hollow cylinder, but if a notch 18 is provided by cutting out a part of the side part at the top and bottom, tightening with the tightening screw 17 is possible. The lateral expansion of the member 13 in response to the force is much greater than would otherwise be the case, so that a better-performing anti-swivel mechanism 8 can therefore be realized.

〔Effect of the invention〕

As described above, when the mechanism of the present invention is in use, it is possible to get on and off the bed while grasping the grip part 9, so that it is possible to easily get on and off the bed for a person to be assisted, such as a patient. Just by standing it upright in the head-to-foot direction, you can create an extremely convenient storage situation, which is very space efficient.In addition, in this storage situation, the shelf members also function as side fences, so you can use the side fences. There is no need to provide a separate bed, and therefore the cost of the bed can be reduced.
