Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telescopic shelves which are constructed so that shelves can extend and contract in the longitudinal direction.

[0002]

2. Description of the Related Art Conventionally known telescopic shelves are:
For example, as described in JP-A-9-238790, a sub-shelf member is nested with respect to a main shelf member, and is slid in the longitudinal direction and adjusted to expand and contract to a predetermined length. ,
Through the slits formed at the front and rear edges of the main shelf member, the sub-shelf member is fixed to the main shelf member by screwing, and each of the shelves composed of these is supported at the four corners with respect to the column. When the length of the shelf is adjusted again, loosen the screws on each shelf and adjust the length of the sub shelf relative to the main shelf when adjusting the length of the shelf again. And
Screw it again.

[Problems to be solved by the invention]

[0003] The problem here is that at least the left and right supports located at both ends of the shelf are not connected to each other, so that the screws for fixing the sub-shelf to the main shelf become loose. In addition, there is a possibility that the support of the shelf board becomes unstable due to an irregular interval between the columns and the inclination of the columns. In addition, since the slits and screws are exposed on the front of the shelf, the appearance is impaired. In addition, since the screw hits the edge of the slit to support the shelf load, especially when the shelf length is increased, the overlap of the main and sub shelf members is reduced, and the center part of the shelf is There is a possibility that the strength of the shelf board is reduced due to bending.

The present invention has been made based on the above circumstances, and a first object of the present invention is to provide a structure in which left and right support side plates (posts) are connected to each other and the length of a shelf plate is long. An object of the present invention is to provide a telescopic shelf device that can easily and stably support a shelf board by having a structure that can cope with the expansion and contraction of the shelves.

[0005] A second object of the present invention is that the shelf is composed of a main shelf and a sub-shelf, and a sufficient shelf load is applied irrespective of expansion and contraction. Another object of the present invention is to provide a telescopic shelf device that has a structure that can be supported and that is designed so that a means for fixing the main and sub shelf members to each other does not impair the appearance.

It can also be supported by the left and right support side plates 2 and 2. In this way, by adopting a structure in which the sub-shelf members 5b and 5c enter and leave from the left and right, the main shelf member 5a can be supported from the left and right even when the space between the left and right side plates is wide, resulting in a stable support structure. .

[0012] Instead of the left and right supporting side plates, four supporting columns can be used. In this case,
It is better in terms of stability to fix the left and right support columns to each other with crosspieces.

The slide guides 1, 1 described above may be provided at the upper end on the rear side of the side plate, and the other ends 3b, 3b of the support rods 3, 3 may be slidably adjusted with respect to the slide guides 1, 1. In this case, one end 3a of the support rod 3,3,
3a is opposite to the above-described embodiment, and the supporting side plates 2, 2
Pivoted at the rear upper end.

FIG. 6 shows another embodiment of the first fixing means 4, in which a pin 104b is projected from the sliding member 14, and the pin 104b is slit (sliding guide 1) and the supporting rod 3 is provided.
And is fixed with a nut 104a through a hole 3c provided in the other end 3b of the second member. In this embodiment, for convenience of assembly, a slit (slide guide 1) may be opened at the lower end of the support side plate and closed by a cap or the like.

[0024]

The present invention has been described in detail above, and the upper and lower sides of the support side plates (posts) on the left and right sides of the shelf board are interconnected by a cross-structured support rod, so that the length of the shelf board can be expanded and contracted. Even if it is adjusted, since it has a structure that can cope with it, it is possible to easily and stably support the shelf board. Further, even if a part of the bolt or nut connecting the members is loosened, the distance between the left and right side plates does not change.

Further, each shelf member is provided with a main shelf member provided with a guide rail below the shelf surface and a slider slid along the guide rail below the shelf surface. The guide rail is formed by bending at least one sub-shelf member inwardly from the front and rear edges of the main shelf member into an L-shape, and a slider is formed at the front and rear edges of the sub-shelf member. The shelf is slidably supported between the shelf surface of the main shelf member and the guide rail, so that the shelf is configured to be extendable and contractible by the main shelf member and the sub shelf member. And a sufficient shelf board load can be supported.

The second fixing means includes a slit formed along the lower side of the guide rail and a plurality of screw holes provided at a required pitch in the longitudinal direction below the slider of the sub-shelf plate member. By using a screw that is screwed into one of the screw holes via the slit, fixing screws and the like do not appear when viewed from the front, and the appearance of the shelf device is not impaired.

Further, by making the sub-shelf members move in and out from the left and right sides of the central main shelf member to expand and contract the shelves to the left and right, the main shelves can be expanded even if the distance between the left and right side plates becomes wide. The member can be supported in a balanced manner from the left and right, and a telescopic shelf device excellent in strength can be provided.
