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 is 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 fence is held in a standing state in which a vertical frame pivotally mounted on the side frame of the bed, an upper horizontal frame, and the vertical frame and the upper horizontal frame are interposed. In addition, there are a type in which the whole body is folded, and a type in which the side fence is formed in two and can be folded separately.

[0003]

However, in any type, a folding space is provided so that it can be folded on the side frame. Therefore, in the standing state of the side fence, the folding space is provided. The space becomes an open space and cannot cover the entire side 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]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a base cross rail extending over the entire length of the side frame on a side frame of a bed, and a post at the center of the base cross rail. Hollow pillar receiving portions for holding via a locking mechanism are provided to project vertically, and on both sides of the central portion of the base horizontal rail, a foldable first portion directed toward the central portion of the base horizontal rail is provided. First and second side fences are provided. Each of the first and second side fences has a plurality of vertical bars whose one end is axially attached to the base horizontal rail, and a hollow shape which is axially attached to the other ends of these vertical rails. An upper cross rail, the pillar has a leg portion and an arm portion that is perpendicular to the leg portion, and while the leg portion is fitted into the pillar receiving portion and held through a locking mechanism, It is characterized in that the arm portion is fitted into the hollow upper horizontal rail of the first and second side fences. In addition, the locking mechanism is locked in the locking groove by a plurality of locking grooves formed along the legs of the support pillar and by elastically projecting into the support receiving portion in the support pillar receiving portion. And a locking member.

[0005]

In the folding side fence according to the present invention, the first and second side fences wobble by inserting the leg of the support into the support receiving portion at the center of the base cross rail and fixing it by the locking mechanism. It is held in a standing position without being. At this time, the first
The side fences and the second side fences are in a state where the arm portions of the columns are fitted into the upper horizontal rails from the openings of the hollow upper horizontal rails of the first and second side rails, but the columns are fixed. Therefore, the first and second side fences exhibit a sufficient holding force even in the longitudinal direction of the side frame. Here, when folding the first and second side fences,
The locking member of the locking mechanism in the strut receiving portion is disengaged from the locking groove in the leg portion of the strut against the elastic force. To do. Then, by pushing the support pillar from above, the leg portion of the support pillar descends so as to slide through the hollow support receiving portion. Along with this, the hollow upper horizontal rails of the first and second side fences slide toward each other in the central portion under the restraint of the arm portions of the support pillars, and the first and second side fences have a plurality of vertical rails. It will be folded along with the collapse of the crosspiece. In this way, since the first and second side fences are oriented toward the center and fall down, there is no need for a folding space on the headboard side or the footboard side.
The bedside can be fully covered.

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 is provided on a side frame 3 of a bed 2 on a side frame 3 and a base cross rail 4 extending over the entire length of the side frame 3.
And a hollow pillar receiving portion 5 vertically projecting from the central portion of the base horizontal rail 4, and the leg portion 6a of the pillar 6 is pierced into the pillar receiving portion 5 so as to be centered on the central portion of the base horizontal rail 4. In contrast,
The first and second side fences 7, which can be folded toward the center,
8 is provided. The first and second side fences 7 and 8 have a plurality of vertical bars 7a and 8a whose one end is pivotally attached to the base horizontal bar 4.
And a hollow upper horizontal rail 9 axially attached to the other ends of these vertical rails 7a and 8a. The upper horizontal rail 9 has an opening 10 directed toward the center, and the arms 6b, 6 of the support column 6 are provided.
The c is inserted into the upper horizontal rail 9 through the opening 10. Further, the strut receiving portion 5 has a locking mechanism 1
1 is provided, and this locking mechanism 11 locks a locking member, that is, the stopper pin 14 into the locking groove 12 formed in the leg portion 6a of the column 6 by the elastic force of the spring member 13, It is configured so as to be projected and locked inward.

According to the folding side fence 1 according to the present invention, the leg portion 6a of the column 6 is inserted into the column receiving portion 5 at the central portion of the base cross rail 4 and is fixed by the locking mechanism 11. The first and second side fences 7 and 8 are held in a standing position without wobbling. At this time, the first side fence 7 and the second side fence
The side fence 8 is a state in which the arms 6b and 6c of the pillar 6 are fitted into the upper horizontal rail 9 through the openings 10 of the hollow upper horizontal rails 9 of the first and second side rails 7 and 8. Since 6 is fixed, the first and second side fences 7 and 8 exhibit sufficient holding force even in the longitudinal direction of the side frame 3. Here, when the first and second side fences 7 and 8 are folded, the stopper pin 14 of the locking mechanism 11 in the pillar receiving portion 5 resists the elastic force, and the locking groove in the leg portion 6a of the pillar 6 is held. Detach from 12. Then, by pushing in the pillar 6 from above, the leg portion 6a of the pillar 6 descends while sliding through the hollow pillar receiving portion 5. Along with this, the first and second side fences 7,
The hollow upper horizontal rail 9 of 8 slides under the restraint of the arm portions 6b and 6c of the support column 6 so as to be directed toward the center of each other, and the first and second side fences 7 and 8 include a plurality of vertical rails 7a, It will be folded with the fall of 8a. In this way, the first and second side fences 7 and 8 are configured to fall toward the central portion, so that a folding space on the headboard side or the footboard side is unnecessary, and the bedside is entirely covered. be able to.

[0008]

As described above, according to the present invention, since the first and second side fences are oriented toward the center and fall down, a folding space on the headboard side or the footboard side is unnecessary. The bedside can be covered entirely.
