BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf board with adjustable width in a cabinet or the like provided in a room.

[0002]

2. Description of the Related Art Conventionally, there are various kinds of shelf boards for adjusting the length of the shelf boards by expanding and contracting. For example, in a pipe shelf in which a plurality of pipes are connected in parallel, the shelf rail pipes are inserted from the left and right sides. There is a telescopic shelf that allows the length of the pipe to be adjusted by sliding it.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a front and rear width of a shelf board that can be adjusted in accordance with the width of a book or article placed on the shelf board.

[0004]

Means for Solving the Problem A small width auxiliary plate of the same length is attached to the front side of a horizontally long rectangular shelf plate, and a plurality of connecting rods for connecting the auxiliary plate and the shelf plate are arranged at appropriate intervals. The front end edge of the shelf board is inserted perpendicularly and slidably back and forth, and an enlarged portion for locking the inside of the shelf board is provided at the rear portion of the insertion of the connection rod. Attach a sliding guide piece to the back surface of the shelf board so that the enlarged part of the connecting rod engages with the rear end of the sliding guide piece to prevent the connecting rod from coming off, and to make the sliding of the connecting rod smooth. The twist of the auxiliary plate and the shelf plate is prevented.

[0005]

[Operation] A space is formed between the auxiliary plate and the front edge of the shelf plate by sliding the insertion part of the connecting rod, which has the front end fixed to the lower surface of the auxiliary plate, forward and sliding it from the front edge of the shelf plate. The front and rear width of the shelf is expanded to form a wide shelf plate, and the expansion of the rear end of the connecting rod engages with the rear end of the sliding guide piece on the inner side of the shelf plate to stop the expansion and reduce the width of the shelf. Keep it constant. The sliding guide piece attached to the back of the shelf at the connecting rod insertion part prevents the connecting rod from tilting in the left-right direction to allow smooth forward and backward sliding, and also prevents twisting of the shelf and auxiliary plates.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 of the accompanying drawings is a perspective view of a shelf plate according to an embodiment of the present invention with a part of the right side cut away, with reference numeral 1 being a shelf plate, 2 is an auxiliary plate, 3 is a connecting rod and 4 is a sliding guide piece. In each drawing, F indicated by an arrow is the front. The shelf board 1 is formed by bending both front and rear edges of a horizontally long rectangular flat plate so as to face each other downward in an L shape to form a front edge 1a and a rear edge 1b. It is a slender curved plate that has a width smaller than that of the shelf board 1 and is divided into two equal parts on the left and right to match the entire length, and a bent edge 2b is formed diagonally rearward from the front end of the upper surface portion 2a to the lower part. They are connected to each other by connecting rods 3 ...

In the plurality of connecting rods 3, ..., the front end portion 3a of each of the straight rods is welded to the back surface of the upper surface portion 2a of the auxiliary plate 2, and the sliding portion 3b at the rear portion is connected to the front end edge 1a of the shelf plate 1. On the other hand, the front end is inserted into the inside of the shelf plate so as to be slidable forward and backward in a straight line, and the rear end of the sliding portion 3b is cut into a forked shape to form an enlarged portion 3c. (See FIGS. 1, 2 and 3)

The plurality of sliding guide pieces 4 ... Form a semi-cylindrical cylindrical curved surface portion 4a into which the connecting rod 3 is inserted at the central portion of each of the flat plate small pieces, and extend on both left and right side portions of the curved surface portion 4a. The two flanged pieces 4b and 4b are welded to the central portion of the back surface of the shelf board 1 and are juxtaposed so as to correspond to the respective connecting rods 3. (See FIGS. 1, 2 and 3)

FIG. 4 is a partial perspective view of one side of a shelf board of the present invention showing an installed state, wherein reference numeral 5 is a partition wall side wall, 6 is a back wall, and 7 is a corner. The columns 8 standing upright at the corners indicate the shelves. Both the side wall 5 and the back wall 6 are formed by fitting a pair of groove-shaped edge members 5a and 6a on the upper and lower edges of a flat plate having an appropriate thickness, and as shown in FIG. The partition wall is formed in a U-shape in plan view by inserting and engaging with the concave groove 7a and fixing it, and connecting both side walls 5, 5 and the back wall 6 to each other at right angles.

As shown in FIG. 4, the shelves 8 are provided with locking claws 8 a projecting from the rear end of a substantially triangular plate member, which are inserted into the outer peripheral groove 7 a of the column 7, and then the groove bottom. It is engaged with and fixed to the peripheral surface of the pillar 7 by engaging with a locking hole (not shown) provided in the rack, and the lower surface of the side end portion of the shelf board 1 is placed on the horizontal upper side portion 8b. The plates are supported, and the shelf plates are supported by the two shelf supports opposite to each other at both ends of the shelf plates, and the shelf plates are installed between the left and right side walls of the partition wall. (See FIG. 4 and FIG. 5.) Reference numeral 9 in FIG. 4 is a cap body that is inserted into the upper end of the column 7, and reference numerals 5 b and 6 b in FIG. The locking claws projecting from the end and inserted into and engaging with the locking holes of the column 7 are shown.

FIG. 6 is a perspective view showing a whole view of a usage example of the shelf board, in which a desk board is formed in a space inside the partition wall constituted by the partition wall and the shelving means shown in FIGS. 4 and 5. It shows a state in which 10 is installed and a chair 11 is installed in the front empty space of the desk board 10 so as to perform office work, and necessary documents, books, booklets, files, etc. are set up on the shelf board. The auxiliary plate 2 is pulled out or pushed in according to the front-back width of the books to adjust the width of the shelf for use.

[0012]

[Effect of device]

 An auxiliary plate is attached to the front side of the shelf plate, and a plurality of connecting rods are slidable in an orthogonal shape between the shelf plate and the auxiliary plate, and the front and rear widths of the shelf plate can be adjusted wide and narrow by sliding the connecting rods back and forth. With this configuration, it is easy to arbitrarily adjust the shelf width according to the front and rear widths of books and articles placed on the shelf board, and the shelf width can be evenly adjusted to the left and right. The enlarged part provided at the rear end of the connecting rod engages with the rear end of the sliding guide piece inside the shelf plate to prevent the connecting rod from being pulled out forward and to keep the shelf width constant. . The sliding guide piece attached to the back of the shelf plate prevents the horizontal movement of each connecting rod and makes it slide back and forth smoothly, and also prevents the shelf plate and auxiliary plates from twisting and tilting. Makes it easy to adjust the width. Further, the shelf board of the present invention is not limited to the illustrated embodiments and usage examples, and has a versatility that it can be used in an arbitrary wide range as needed.
