Description

  The present invention relates to a foldable side fence having a function of preventing pinching, which prevents a hand or the like from being pinched when folded on a foldable side fence mounted on a side frame such as a bed. It is.

  Until now, as is well known, the side rails provided on the side frames of beds and the like (ordinary beds, transfer beds, ICU beds) are indispensable for safety measures. For example, the foldable side fence can be folded and raised on the bedside frame, and is maintained in a raised state by a lock mechanism, and is removed one by one when getting on and off the bed. Since it is not necessary and it only needs to be folded, it exhibits an excellent effect without bothering a caregiver or the like.

By the way, the present applicant has proposed such a folding-type side fence until now. For example,
(Japanese Laid-Open Patent Publication No. 9-121982) In this foldable side fence 1, a lower horizontal beam 3 that is mounted on a side frame 2 such as a bed, and a lying down in one direction on the lower horizontal beam 3. A plurality of support columns 4 that can be attached, an upper horizontal beam 5 attached to the tops of the plurality of columns 4, and an upright holding mechanism that maintains the column 4 in an upright position between the columns 4 and the upper horizontal beam 5. 6 is provided with a fall prevention means 7 that prevents the plurality of columns 4 from falling on the lower horizontal rail 3 halfway (see FIG. 15). The standing position holding mechanism 6 is provided in the cover member b in a fitting hole (not shown) provided in the receiving member a on the upper end side of the column 4 and elastically locks the fitting pin p at the tip. The support member 4 is made up of a lever member c, and the support pin 4 is maintained in an upright state by fitting a fitting pin p at the tip of the lever member c into a fitting hole in the receiving member a. As shown in FIG. 16, the lodging prevention means 7 is provided in the vicinity of both end portions of the lower horizontal beam 3, and a base member 8 screwed to the lower horizontal beam 3, and a standing fall on the base member 8. The column holding member 10 is mounted so as to be capable of being urged by the spring member 9 at all times in the standing position, and is manually provided to be able to fall down against the urging force. That is, the support member 10 is attached to the base member 8 in a slightly inclined state so that the support member 4 can be easily received on the top side. The support member 10 is attached to the top side. A finger hook 11 for pulling down with a finger against the spring force of the spring member 9 is provided.

However, when the folding side fence 1 is folded, it is necessary to operate in the following procedure.
(1) The unlocking operation of the standing position holding mechanism 6 is performed with one hand, and the other hand is lying down while supporting an appropriate position of the upper horizontal rail 5.
(2) The plurality of struts 4 fall down, and the strut 4 closest to the fall prevention means 7 hits the top of the strut holding member 10 of the fall prevention means 7, thereby temporarily stopping the fall (see FIG. 17).
(3) Since the upper horizontal rail 5 is in a high state as it is, the column holding members 10 of both the fall prevention means 7 are pulled down one by one by placing a finger on the finger hooking portion 11 at the top of the column holding member 10. By operating, the top part of the support | pillar holding member 10 is removed from the support | pillar 4, and it lies down completely (refer FIG. 18).
Therefore, since the operation of pulling down the column holding members 10 of both of the fall prevention means 7 is difficult with one hand, the operation of pulling down the column holding members 10 of both of the fall prevention means 7 must be performed simultaneously. However, at present, the hand holding the upper crosspiece 5 is released and simultaneously released with both hands.
As described above, it is difficult to release both the fall prevention means 7 with one hand, and at the same time, the support column 4 falls over the operating hand during the releasing operation, so that the hand is pinched. High risk.
