Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a side shelf that is constructed on the side of a bed, etc., to prevent bedding, etc. from falling off, or a patient, etc., from falling. The present invention relates to a side fence in which the constructed support pipe is fitted into a fitting portion formed on the upper side of a side frame of a bed or the like to be in use.

(Prior art) In a side fence in which a support pipe constructed on the side fence body is fitted into a fitting part formed on the upper side of a side frame of a bed or the like to be in use, it can be easily removed when necessary. In order to do this, there are few devices that have a mechanism to prevent them from coming off.

(Problem that the invention aims to solve) If the device does not have a mechanism to prevent it from coming off, it may come off unexpectedly or easily, and there are cases where an old man, etc., has pulled it out and used it as a weapon. There are various problems caused by easy removal. However, it is very troublesome if it cannot be easily removed when necessary, such as when making a medical examination, making a bed, or getting on and off a patient.

The present invention aims to solve such conventional problems.

(Means for solving the problem) The structure of the present invention to solve the above problem is as follows.
To explain with reference to the drawings corresponding to the embodiments, the side fence for a bed or the like of the present invention has an operating rod 3 movably provided in a support pipe 2 formed in a side fence main body 1, and one side of the side fence is provided with a support pipe 2. 2, and a flange 4 is provided on one side of the operating rod 3,
A cylindrical stopper body 5 is interposed between the collar portion 4 and the lower end of the support pipe 2, and is elastically deformed by axial compression and can freely protrude in the radial direction. A rolling operation lever 10 is provided on the upper side of the support pipe 2 located at , and a communication hole 6 is provided on the side of the support pipe 2 corresponding to this rolling operation lever 10 .
and the upper part of the operating rod 3 are connected by a connecting link 11 through the communicating hole 6 so as to form a toggle link mechanism.

(Function and Examples) To explain the function of the above configuration together with the embodiment shown in the drawings, first, as shown in FIGS. 1 and 2 a, when the rolling operation lever 10 is rotated counterclockwise, In this case, the operating rod 3 is supported at a lower position, and therefore the cylindrical stopper body 5 is not compressed between the collar portion 4 and the lower end of the support pipe 2, and therefore does not protrude in the radial direction. Therefore, the lower part of the support pipe 2 can be easily inserted into the fitting part 13 formed on the side frame 12 of the bed or the like, as shown in FIG. 1, and can be removed.

After fitting the lower part of the support pipe 2 into the fitting part 13 in this way, the rolling operation lever 10 is moved to the second position.
As it rolls clockwise as shown in Figure b, the operating rod 3 is moved upward by the connecting link 11, so the distance between the collar 4 and the lower end of the support pipe 2 is shortened, and the cylindrical stopper body 5 is compressed. Therefore, this cylindrical stopper body 5 is elastically deformed and protrudes in the radial direction, the outer diameter of this portion increases, and its outer surface comes into pressure contact with the inner wall of the fitting portion 13. In this way, when the rolling operation lever 10 reaches the end point of rolling, the connecting link 11 and the operating rod 3
The rolling operation lever 10, which together constitute a toggle link mechanism, is supported beyond the toggle position. Therefore, the operating rod 3 is supported in the upwardly moved position, and the cylindrical stopper body 5 is maintained in the above-mentioned compressed state, that is, the state in which it protrudes in the radial direction. The state in which the support pipe 2 is in pressure contact with the inner wall is maintained, and the lower part of the support pipe 2 is prevented from coming off from the fitting portion 13 due to the frictional force of this pressure contact portion. Therefore, it is possible to prevent the support pipe 2 from accidentally coming off, or from being easily pulled out by a mentally unstable elderly person or the like and using it as a weapon.

Next, in the state shown in FIG. 2b above, place a
When the rolling operation lever 10 is rolled counterclockwise by pulling or pushing point b, the operating rod 3 moves downward and the distance between the collar 4 and the lower end of the support pipe 2 increases. However, the cylindrical stopper body 5 is decompressed and no longer protrudes in the radial direction.
In this way, the lower part of the support pipe 2 can be easily removed from the fitting part 13 again as described above. Therefore, the side rails can be removed with a simple operation when necessary, for example, for examination, treatment, bed making, and getting a patient on and off the bed.

In the embodiment, the cylindrical stopper body 5 shown in FIGS. 1 and 2 is constructed as a cylindrical body made of a material such as rubber that is easily elastically deformable.
Further, the cylindrical stopper body 5 shown in FIG.
are formed alternately from both ends in the axial direction so as to be easily elastically deformable. The operation of this embodiment is shown in FIGS. 3b and 3c, which corresponds to the operation shown in FIGS. 2a and 2b.
Further, in the above embodiment, the operating rod 3, the collar portion 4, the cylindrical stopper body 5, and the rolling operating lever 10 for operating are provided only for one support pipe 2. It can also be provided for multiple books.

(Effects of the invention) As described above, the present invention provides a side fence in which the support pipe formed on the side fence body is fitted into the fitting part formed on the upper side of the side frame of a bed etc. to be put into use. Since a cylindrical stopper body that can be elastically deformed by axial compression and protrude in the radial direction is formed at the bottom of the support pipe, when used as a side fence, the support pipe can be removed from the fitting part. This prevents the risk of it being accidentally pulled out, or easily removed by someone who is not in a normal state of consciousness, such as an elderly person, and using it as a weapon. has the advantage that it can be removed with easy operation. In particular, in the present invention, the operation of the cylindrical stopper body is performed by the toggle link mechanism of the above configuration, so even if the compression force of the cylindrical stopper body is large, sufficient compression force can be applied with a light operation force. At the same time, it can be operated with one touch without requiring the time and effort of a mechanism that uses operating screws, etc., and the rolling operation lever that operates the cylindrical stopper body is located within the space occupied by the side fence body. Since it is located in the corner, it does not get in the way except when operating
Furthermore, it can be operated by a conscious patient on a bed or the like, and there is an advantage that the patient does not have to bother the nurse when getting on and off the bed.
