BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable side fence capable of completely covering a bedside surface.

[0002]

2. Description of the Related 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. As the side fences, there are those having various structures such as a fence that can be simply inserted into a side frame, a foldable fence, and a fence that rotates and descends. By the way, of the above-mentioned side fences, the foldable side fences include a vertical frame whose one end is axially attached to the side frame of the bed, and an upper horizontal frame whose other end is axially attached to the side frame of the bed. Some of them are made up of a standing position holding mechanism for holding the frame in a standing position, and the one that folds the whole or the side fence itself is divided into two parts that can be folded separately. There is a format that can.

[0003]

However, any type has a folding space so that it can be folded on the side frame,
For this reason, when the side fence is in the standing position, the folding space becomes an open space and cannot cover the entire side surface of the bed. The present invention has been made to solve the above problems, and an object thereof is to provide a foldable side fence capable of covering the bedside surface entirely.

[0004]

In order to solve the above-mentioned problems, the present invention provides guide posts near both ends in the longitudinal direction of a side frame of a bed, and a lower cross rail is provided between the guide posts. while the shaft wearing one end of telescopic plurality of struts to the lower horizontal桟上, pivotally attached a hollow upper rung to the other end of the plurality of struts, said plurality of struts, the outer
It has a pipe part and a rod part that moves back and forth in the outer pipe part in a buffer manner.
The rod part on the lower horizontal rail to one side.
The guide shaft is inserted through the upper horizontal rail, and the guide shaft is attached to the guide post via a locking and holding mechanism.

[0005]

[Function] In the folding side fence according to the present invention, the upper cross rail is
The guide shaft is held by the guide post together with the plurality of stanchions via the locking and holding mechanism, thereby standing.
Here, when any one of the lock holding mechanisms is operated to release the lock holding state and the lock holding mechanism is lowered along the guide post, the upper horizontal rail slides along the guide shaft. With respect to the plurality of columns , the rod portion is retracted into the outer tube portion from the side where the locking holding mechanism is lowered in a buffer manner.
Bending and probing while shrinking more gradually. And
By operating the locking and holding mechanism on the other side to release the locked and held state, and by lowering the locking and holding mechanism along the guide post, the upper horizontal rail can be entirely folded on the side frame. Becomes

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A folding side fence according to the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 indicates a foldable side fence, and the foldable side fence 1 includes a guide post 4 in the vicinity of both ends of the side frame 3 of the bed 2 in the longitudinal direction, and a lower cross rail 5 between the guide posts 4. One end of a plurality of stretchable columns 6 is pivotally mounted on the lower horizontal rail 5, the hollow upper horizontal rail 7 is pivotally mounted on the other end, and a long guide shaft 8 is attached to the upper horizontal rail 7. And the guide shaft 8 is attached to the guide post 4 via a locking and holding mechanism, that is, a stopper mechanism 9 which is a friction locking mechanism.

The plurality of columns 6 are composed of an outer pipe portion 6a and a rod portion 6b which moves forward and backward in a buffer manner in the outer pipe portion 6a. The rod portion 6b is located on the lower horizontal rail 5 in one direction. The outer pipe portion 6a is attached to the upper horizontal rail 7 via the upper hinge 11 (see FIG. 2).

The upper horizontal rail 7 has a length slightly shorter than that of the guide shaft 8 which is stretched between the guide posts 4 via a stopper mechanism 9. It is configured to be slidable on the guide shaft 8 via a slider member 12 (for example, a linear bearing member or the like) provided on the inner surface.

The stopper mechanism 9 is configured to hold the upper horizontal rail 7 and the guide shaft 8 at an arbitrary position by frictional force. In addition, in order to release the held state,
The stopper mechanism 9 includes an operation lever 13 for removing frictional force.
Is provided. That is, when an example of the stopper mechanism 9 is shown in FIG. 3, the housing 14 is slidably mounted on the guide post 4, and the end portion of the guide shaft 8 is axially mounted in the housing 14 and operated. The lever 13 is pivotally mounted via a spring member. The operation lever 13 is inserted into the guide post 4 through the locking hole 15. One of the operating levers 13 is displaced by a spring force, and the position of the locking hole 15 is displaced so that the edge of the locking hole 15 is pressed against the guide post 4 to contact the upper horizontal rail 7 and The guide shaft 8 is held at an arbitrary position.

According to the folding side fence 1 of the present invention, the upper horizontal rail 7 is held upright by holding the guide shaft 8 on the guide post 4 via the stopper mechanism 9 together with the plurality of columns 6. It is in a state (see FIG. 4). Here, when any one of the operation levers 13 of the stopper mechanism 9 is operated against the spring force to release the frictional lock and the stopper mechanism 9 is lowered along the guide post 4, the upper horizontal rail 7 Slides along the guide shaft 8 via the slider member 12, and the rods 6b of the plurality of columns 6 are buffered to the outer pipe portion 6a from the side where the stopper mechanism 9 is lowered. Pipe section 6
As the column 6 bends and falls down by the lower hinge 10 and the upper hinge 11 as a result, the upper column bar 7 and the guide shaft 8 incline and descend (FIG. 5 or FIG. 6). Then, when the stopper mechanism 9 on the other side is operated to release the frictional lock and the stopper mechanism 9 is lowered along the guide post 4, the upper horizontal rail 7 is entirely folded on the side frame 3. (See FIG. 7). At this time, since there is no structure projecting downward from the lower horizontal rail 5 of the side frame 3, it can be applied to a bed provided with a storage box or the like below the side frame 3. Further, any structure can be applied as long as the lower horizontal rail 5 is mounted on the side frame 3. In order to pull up the foldable side fence 1 as described above, the upper horizontal rail 7 is pulled up together with the guide shaft 8 while operating the operating lever 13 of the stopper mechanism 9 on one side, and further, the stopper mechanism 9 on one side is pulled up.
The operation lever 13 may be operated and pulled up.

As described above, when the plurality of columns 6 fall down, the rod portion 6b retracts to the outer tube portion 6a in a buffer manner, and further, both sides of the upper horizontal rail 7 are simultaneously pushed and folded. Rather than folding the guide shaft 8, the upper horizontal rail 7 is slightly shorter than the guide shaft 8.
Even if the support pillars 6 are provided over the entire length of the outer pipe portion 6a
If it is a little longer, the column 6 will not interfere with the guide post 4 when it is pushed down. Therefore, the conventional folding space is unnecessary, and almost the entire side surface of the bed 2 can be covered.

[0012]

As described above, according to the present invention, a plurality of columns are arranged almost all over the bed side, and the locking and holding mechanisms on both sides are operated one by one to shorten the columns. Since it is configured to be folded, the conventional folding space is unnecessary and the bedside can be entirely covered. In addition, since there is no structure that protrudes downward when folded, it can be applied to a bed including a storage box below the bed. Further, any one can be applied as long as the lower cross rail which constitutes the side fence according to the present invention can be attached to the bedside frame.
