The stopper button 23 has a pushing operation portion 23a exposed so as to protrude from the through hole 24 of the stopper main body 22. Guide grooves 5 and 6 are provided on the back surface of a location opposite to the pushing operation portion 23a. Adjustment groove 1 in
2, a projection 27 is provided. With the stopper button 23 having such a configuration, the protrusion 27 is always
A torsion spring 28 is provided so as to be locked in the adjustment groove 12.

The board-mounted full-surface fence 2 according to the present invention is constructed as described above, and its operation will be described below. First, when the entire fence 2 is folded, that is, as shown in FIGS. 2 and 3, when the upper cross member 9 is at a substantially same height as the bottom 11 of the bed 1, when used as a fence, The stopper means 10 of the height adjusting grip 17 at both ends of the upper cross member 9 is released one by one. That is, while holding the height adjusting grip 17, the pushing operation part 23a of the stopper button 23 is pushed in with the thumb (see FIG. 7). As a result, the side opposite to the push-in operation section 23a is lifted up against the biasing force of the torsion spring 28, and as a result, the protrusion 27 on the back side of the location is moved to the guide groove 5,
6, the lock member is released from the adjustment groove 12, and the one side of the upper cross member 9 can be lifted. At this time, the upper cross member 9 is attached to the slide hinge 1.
8 is inclined with respect to the base 18a, and one side of the upper cross member 9 is inclined by the sliding portion 19 sliding in the inner space of the upper cross member 9; The base 1 of the slide hinge 18 which is an open end of the base 9
Since the place where the shaft 8a and the swinging shaft 18b are stopped is covered with the bellows member 20, there is no possibility that a hand or an object will be pinched (see FIG. 5).

When one side of the upper cross member 9 is lifted, the telescopic strut 8 provided between the upper cross member 9 and the lower cross member 7 gradually extends under a predetermined resistance and stands up. Go. When one side of the upper cross member 9 is brought to a desired height, the thumb is pushed into the stopper button 23 by the pushing operation portion 23a.
As a result, the projection 27 on the back side of the part opposite to the push-in operation part 23a is locked by the biasing force of the torsion spring 28 in the adjustment groove 12 in the guide grooves 5, 6, and one of the upper rails The member 9 can be held. Next, similarly, if the other end side of the upper cross member 9 is lifted, the upper cross member 9 is lifted to a desired height,
With all telescopic struts 8 in the extended state,
You can make great use of it.

On the other hand, in order to fold the upper rail member 9 from the state where the upper rail member 9 is held at the highest position, the stopper means 10 in the height adjusting grips 17 at both ends of the upper rail member 9 is released one by one, and the upper rail member 9 is released. The member 9 may be operated one by one and lowered along the guide grooves 5 and 6 (see FIG. 8). In addition, if a part of the telescopic strut 8 is configured to be capable of expanding and contracting under a predetermined resistance, the stopper means 10 can be used.
Even when the release operation is performed, the upper cross member 9 can be prevented from suddenly descending, so that a more stable operation can be performed, and no limbs or other objects are sandwiched between the telescopic struts 8. . Also, since the upper cross member 9 can be held at an arbitrary height position even if it is not at the highest position, it has a minimum function as a fence, but does not hinder the treatment. It is also possible to do so.
