DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a lift-type bed side guard mechanism according to the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a bed 10 to which an elevating bed side guard mechanism 11 according to the present invention is applied. The up / down bed side guard mechanism 11 is configured so that the screen member 12 can be deployed so that the side surface of the bed 10 is guarded by the screen member 12. That is, in the bed side guard mechanism 11, a lower horizontal rail member 16 detachably provided through a mounting means 15 in a mounting hole 14 provided in a side frame 13, and a column is provided at both ends of the lower horizontal rail member 16. The support columns 17, 17 are provided with guide grooves 18 on the sides of the columns 17, 17 facing each other in the longitudinal direction of the side frame 13.
And the upper horizontal rail member 19 is mounted so as to be able to move up and down. A take-up shaft 20 for taking up and holding the screen member 12 is disposed between the lower horizontal bar member 16 and the upper horizontal bar member 19 in a state where the screen member 12 is constantly urged to be wound. . The screen member 12 is arranged so as to be deployed between the lower horizontal rail member 16 and the winding shaft 20 when the upper horizontal rail member 19 is lifted, and is wound and accommodated in the winding shaft 20. Screen member 1
2a, and a second screen member 12b that is arranged so as to be developed between the upper horizontal rail member 19 and the winding shaft 20 and is wound and housed on the winding shaft 20. That is, in the bed side guard mechanism 11, the first and second screen members 12a and 12b are pulled out from the winding shaft 20 so as to expand against the urging force by lifting the upper horizontal rail member 19, and the bed 10 At the position where the upper horizontal rail member 19 is lifted to the highest position, the stopper pin (described later) of the lock mechanism 21 provided on the upper horizontal rail member 19 is engaged with the lock hole 21 a formed in the support pillar 17, 17 while the side surface is covered. To hold it.

The screen member 12 is made of a woven cloth made of, for example, a relatively coarse weave of synthetic resin yarn or a knitted mesh cloth so that the shielded side surface of the bed 10 can be seen through from the outside to some extent. Can be applied.

The lower horizontal rail member 16 and the upper horizontal rail member 19 are made of extruded aluminum material, and the lower horizontal rail member 16 has a side frame 13 having a total length substantially between the headboard 22 and the footboard 23. It has dimensions comparable to. The mounting means 15 for detachably fixing the lower horizontal rail member 16 to the mounting holes 14 on both outer sides of the side frame 13 is not shown in detail. While being inserted through a cylindrical member 25 having a diameter that can be fitted into the mounting hole 14,
A nut 26 is screwed onto the fastening bolt 24. The cylindrical member 25 and the nut 26 are in contact with each other with a slope, and the fastening bolt 24
By tightening, the cylindrical member 25 and the nut 26 are
The mounting holes 14 are deviated from each other via a slope which is a contact surface.
And the lower horizontal rail member 16 is fixed so as not to fall off.

The upper horizontal rail member 19 is a hollow frame member as shown in FIG. 2, and the movable element 2 is fitted at both ends thereof movably along guide grooves 18 provided in the columns 17, 17.
7, 27 are fitted. In addition, the upper horizontal beam member 1
9, the upper end of the second screen member 12 b of the screen member 12 is screwed to the lower surface side of the screen member 12 via a mounting frame 28.

As shown in FIG. 3, the lock mechanism 21 has a pair of stopper pins 29 housed in a hollow upper horizontal beam member 19. The stopper pins 29 are always urged by the spring member 30 interposed between the bases 29a of the stopper pins 29, so that the upper horizontal rail member 19
The tip ends protrude from the movers 27, 27 at both ends. In addition, the base portion 29a of the stopper pin 29 includes
The stopper pin 29 against the urging force of the spring member 30
(For unlocking operation) for operating to pull the tip of the slider into the moving elements 27, 27
Is screwed. And such knobs 31, 31
Are protruded from long holes 32 for operation regulation formed in the center of the upper horizontal rail member 19.

The screen member 12 arranged between the lower horizontal rail member 16 and the upper horizontal rail member 19 configured as described above, which is arranged so as to cover the side surface of the bed 10 and can be raised and lowered, is shown in FIG. As shown in FIG. 4, the first and second screen members 12a and 12b having substantially the same dimensions are attached to each other, and the lower end of the first screen member 12a is attached to the lower cross member 16 while the upper end is taken up by a winding shaft 20.
And the lower end of the second screen member 12b is attached to the take-up shaft 20, while the upper end is attached to the lower surface of the upper horizontal rail member 19 as described above. In the drawing, the first and second screen members 12a, 12b are simultaneously rewound in the same direction by being urged counterclockwise to accommodate them.

In the bed side guard mechanism 11 as described above, in order to cover the side surface of the bed 10 with the screen member 12, the columns 17, 17 are supported by the upper horizontal beam member 19.
To bring the upper cross member 19 to the highest position. At this time, the winding shaft 20 moves up along the guide groove 18 of the columns 17, 17 together with the upper horizontal rail member 19, and the first and second screen members 12a, 12b constituting the screen member 12 are wound. Each of the shafts 20 is drawn out and deployed against the urging force to cover the side surface of the bed 10 (see FIG. 4). In this case, since the screen member 12 is a relatively coarse woven fabric, the upper side of the bottom can be seen through from the outside. Further, when the first and second screen members 12a and 12b are unfolded, the winding shaft 20 functions as an intermediate bar, and there is no problem in strength. By bringing the upper horizontal rail member 19 to the highest position, the pair of stopper pins 29 in the lock mechanism 21 is caused to be biased by a spring member 30 so that the column 1
As it is locked in lock holes 21a provided in 7, 17,
In this state, the screen member 12 can be held (see FIG. 1).

On the other hand, in order to lower the screen member 12 and open the side surface of the bed 10, the knobs 31, 31 of the lock mechanism 21 are connected to the elongated holes 32, 3
Under the restriction of 2, the pull-back operation (lock release operation) of the stopper pin 29 is performed simultaneously against the urging force of the spring member 30. In this case, the lock cannot be released unless the pair of stopper pins 29 are simultaneously pulled back, so that the screen member 12 does not fall down through the upper horizontal rail member 19 without being blind, and the child or dementia patient Mischief operation can be avoided. When the screen member 12 is lowered, the first and second screen members 12
Since a and 12b are simultaneously urged to be wound and accommodated in the winding shaft 20 in the same direction, they do not sag, and there is little possibility that limbs, futons, or the like are involved.

As described above, the bed side guard mechanism 11
The screen member 12 is made of an aluminum material, and the screen member 12 is made of synthetic resin yarn. Therefore, the screen member 12 is lightweight, easy to operate, and covers the entire side surface of the bed. As it can be done, it can sufficiently fulfill the function of a pipe type folding side fence called a conventional side rail, and there is little involvement of limbs, futons, etc.Even if something is involved,
Since it is a lightweight and flexible screen member 12 in which a synthetic resin thread is woven, there is no risk of injury. For this reason,
It is highly versatile in that it can be applied to children's beds in addition to ordinary beds.

[0014]

As described above, the present invention is not a pipe frame type as in the prior art, but is constituted by an upper cross member and a screen member. In this case, the entire side surface of the bed can be covered, and at this time, the winding shaft for winding the screen member functions as an intermediate crosspiece, so that there is no problem in strength and the function of the side fence can be sufficiently performed. Moreover, limbs, futons, etc. are less likely to be involved. Even if something is involved, there is no danger of injury due to the light and flexible screen member woven with synthetic resin thread. For this reason, the application range is wide, for example, it can be applied to a children's bed in addition to a normal bed.
