Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a height-adjustable insertion-side fence in which the height of the fence is changed to correspond to the position of the back floor while raising the back of the bed. is there.

(Prior Art) Generally, a side fence provided on a side frame of a bed is
It is well known that the patient's body is for preventing an unexpected fall from the bedside. As such side fences, 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 have been commercialized.

(Problems to be Solved by the Invention) By the way, when a side fence having the above-described structure is provided in a bed having a back raising mechanism, the upper end of the side fence has only the abdomen of the patient in a state of raising the back. Therefore, if an emergency occurs in the patient and the patient falls down from the back to the side of the bed, the side fence cannot support the patient's body. Concerns have been pointed out that patients may fall.

The present invention has been made to overcome the above-mentioned problems.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention is attachable / detachable to / from a plurality of insertion holes formed in a side frame of a bed having a back raising mechanism for undulating the back floor. A pair of struts, a pivot member pivotally attached to these struts, and a fence member composed of a central frame pivotally connected to the pivot arm, and the pivot arm and the central frame are pivotally attached to each other. The part is covered with a flexible member, and the holding height of the center frame is displaced by changing the interval between the columns.

The flexible member in the present invention is a bellows type member.

(Operation) According to the present invention, when the bed floor is in the normal position, the columns are inserted into the insertion holes of the side frame of the bed so as to maximize the distance between the pair of columns. Retained.

If a plurality of the insertion holes are formed in the side frame at predetermined intervals, the side fence can be held not only on the back floor but also on the waist floor or the leg floor.

Next, when the caregiver operates the back raising mechanism to raise the back, the caregiver pulls out the pillar of the side fence from the insertion hole. Then, the caregiver pushes the pillars toward the center between the pillars while pulling up the center frame. Here, the fence member bends such that the pivot arm bends and the central frame projects upward.

Next, the support columns are inserted into the insertion holes of the side frames corresponding to the support column intervals. In this state, the central frame is held at a position corresponding to the raised back. Therefore, even if the patient falls from the back to the side of the bed, the patient is supported by the center frame of the fence member, and the worst situation in which the patient falls off the bed can be avoided. Becomes

Further, since the pivotal point between the pivot arm and the central frame is covered by a flexible member, for example, a bellows type member, the pivotal point is not exposed, and there is a risk that the hand is inadvertently caught. Sex is avoided.

(Embodiment) Next, one embodiment of the variable height insertion side fence according to the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a variable height insertion side fence (hereinafter, simply referred to as side fence 1), and this side fence 1 is a side frame of a bed having a back raising mechanism for undulating the back floor. It is detachably attached to 2. That is, the side fence 1 is composed of a pair of columns 3a and 3b and a fence member 4 connected between the columns 3a and 3b.

The fence member 4 includes an intermediate portion of the columns 3a and 3b, rotating arms 5a, 5b, 5c and 5d pivotally mounted at the apex, and a center frame 6 connected between the rotating arms 5a to 5d. Consists of. The rotating arms 5a to 5d and the central frame 6 are connected by hinges 7a to 7d, respectively, and these hinges 7a to 7d are covered by expandable and contractible bellows type members 8a to 8d. .

On the other hand, a plurality of insertion holes 9 for inserting the columns 3a and 3b of the side fence 1 are formed in the side frame 2 of the bed at predetermined intervals, and the insertion holes corresponding to the intervals between the columns 3a and 3b. The side fence 1 is held by inserting it into the side wall 9.

The side fence 1 according to the present invention is constructed as described above. Next, its operation will be described.

A pair of columns 3a, 3b when the bed is in the normal position
The columns 3a and 3b are respectively
It is held in a state of being inserted into the insertion hole 9 of the side frame 2 of the bed.

Further, since a plurality of the insertion holes 9 are formed in the side frame 2 at predetermined intervals, the side fence 1 should be held not only in the back floor but also in the position corresponding to the waist floor or leg floor. You can

Next, when the caregiver operates the back raising mechanism (not shown) to raise the back, the caregiver pulls out the columns 3a and 3b of the side fence 1 from the insertion holes 9. Then, the pillars 3a and 3b are pressed toward the center between the pillars 3a and 3b while pulling up the center frame 6 to narrow the pillars 3a and 3b. Here, in the fence member 4, the pivot arms 5a to 5d pivot upward, and the center frame 6 projects upward and bends.

Next, the columns 3a and 3b are inserted and retained in the insertion holes 9 of the side frame 2 corresponding to the intervals between the columns 3a and 3b.
In this state, the center frame 6 is held at a position corresponding to the raised back. Therefore, even if the patient falls down from the back to the side of the bed, the patient is supported by the center frame 6 of the fence member 4 and the worst situation of the patient rolling off the bed is avoided. Is possible.

Further, since the hinges 7a to 7d of the fence member 4 are covered by the bellows-type members 8a to 8d, the hinges 7a to 7d are not exposed, and therefore the hinges 7a to 7d are inadvertently moved by turning. The danger of being caught is avoided and the safety is excellent.

(Effects of the Invention) According to the present invention, the support heights of the center frames of the fence members are displaced by pressing between the columns of the side fences in the center direction between the columns, and different insertion holes formed in the side frames. By locking to
It can be held at a position corresponding to the back floor. Therefore, even if the patient falls from the back to the side of the bed, the patient is supported by the fence member,
It is possible to avoid the worst case of the patient rolling off the bed.

In addition, since the pivotal point between the pivot arm and the central frame is covered by the flexible member, for example, the bellows-type member, the pivotal point is not exposed, and the hand may be inadvertently caught. Danger is avoided.

As described above, as described above, the operation of the side fence according to the present invention is simple, and the mechanism is simple, so that there is an advantage in that there is no problem in cost.
