Description

[Detailed description of the invention] The present invention is a movable shelf in which a required number of shelves are arranged in three rows in the front and back direction, the rear row of shelves is fixed, and the front two rows of shelves can be moved laterally. , relates to a support device for supporting the upper ends of front row shelves in conjunction with fixed shelves.

Conventionally, in the movable shelf, two guide rails, one for the intermediate shelf and one for the front shelf, were attached to the upper front surface of the fixed shelf, which are necessary for moving the intermediate shelf and the front shelf laterally. For this reason, the number of parts was large, and assembly was time-consuming. The present invention is characterized in that the inside of one rail is used for an intermediate shelf, and the upper surface is used for a front shelf.

The present invention will be explained below with reference to the drawings.

In FIG. 1, 1 is a fixed shelf, 2 is an intermediate shelf, 3 is a front shelf, 4 is a guide rail, 5 is a base, 6 is a sliding door, and 7 is a front shelf guide fitting.

The fixed shelf 1 has a plurality of cabinets 11, 12,
13 are arranged and fixed in parallel on the base 5, and the intermediate shelf 2
And the front shelf 3 has one fewer cabinets 211, 212, 311, 312 than the fixed shelf 1,
Lower rails 51, 52, 5 provided on the base 5
3, 54 and is movable left and right.
51', 52', 53', 54' are the lower rails 5
These are lower stoppers provided at the left and right ends of the shelves 1, 52, 53, and 54 to restrict the movement range of the intermediate shelf 2 and front shelf 3.

4 is a guide rail attached to the upper part of the fixed shelf 1, and as shown in FIGS. 2 and 3, the upper end of the vertical body 41 is bent horizontally into an L shape, and the upper bent piece 411 is bent inside the lower end. A lower folding piece 412 is continuously provided by bending in the same direction, and a sliding door rail portion 413 is provided on the lower folding piece 412. Reference numeral 414 designates upper stoppers of the intermediate shelf 2 and the sliding door 6 provided at the left and right ends of the guide rail.

42 extends the lower end of the vertical portion 421 located at the top of the back surface of the vertical body portion 41 of the guide rail 4 outward.
A horizontal part 422 bent at 90 degrees, a floating prevention piece 423 of the second roller 9 (to be described later) with the upper end of the vertical part 421 folded inward, and a certain gap between the upper surface of the horizontal part 422 and the vertical part 421. Lean upward L
This is a steady rest rail consisting of a support part 425 for the third roller 9 (to be described later) to which a shaped bending part 424 is attached, and a rail attachment piece 426 attached to the lower surface of the horizontal part 422 and having an engaging pawl 427 at the tip. .

8 is the cabinet 211, 212 of the intermediate shelf 2;
It is an intermediate shelf guide fitting attached to both left and right end sides of the rear part of each of the intermediate shelf guide fittings, and has a first roller 81 that rolls around a vertical axis at the tip and a stopper piece 82 formed by raising the side of the tip. 1 roller 81 is the upper bent piece portion 4 of the guide rail 4.
It protrudes rearward so that it is located within 11.

The front shelf guide fitting 7 has left and right frames 71 and 72 formed by bending one end downward and inward in an L shape and the other end downward and outward in an L shape, and one end bent downward and outward in an L shape. It is constructed by assembling a front frame 73 whose other end is bent downward and outward into an L shape, and a rear frame 74 having the same shape as the left and right frames 71 and 72 into a frame shape. The left and right frames 71, 72 and rear frame 74 of the front guide fitting 7 have the same height, and the L-shaped bent portion 731 at the front end of the front frame 73 has a height approximately twice that of the frames 71, 72, 74. The left and right frames 71, 72 and the rear frame 74 are attached at a height with a predetermined distance from the intermediate shelf 2. The rear end surface of the rear frame 74 of the front guide metal fitting 7 rolls around the horizontal axis, contacts the upper surface of the upper bent piece 411 of the guide rail 4, and lowers the lifting prevention piece 423 of the steady rest rail 42. A second roller 9 is attached.

Further, on the upper surface of the rear frame 74, there is a horizontal L-shaped steady rest fitting 11 having a third roller 10 that rolls around a vertical axis on the lower surface of the horizontal end and is located within the support portion 425 of the second guide rail 42. It is attached.

The sliding door 6 has a roller 61 provided on the back surface of the upper part and is placed on the sliding door rail section 413, so that the sliding door 6 can be moved left and right on the front surface of the fixed shelf 1.

As described above, in the front shelf 3, the second roller 9 of the front shelf guide fitting 7, which is provided to protrude rearward from the upper rear surface of the front shelf 3, is connected to the upper bent portion 41 of the guide rail 4.
1 placed on the top surface, and a floating prevention piece 4 is placed on top of it.
23, the intermediate shelf 2 has a first roller 81 of an intermediate shelf guide fitting 8 that protrudes rearward from its rear upper surface.
is supported inside the upper bent portion 411 of the guide rail 4, so there is no risk of the front shelf and middle shelf falling forward, and since the middle shelf and front shelf serve as guide rails, the number of parts is small. It can be manufactured at low cost.

In order to further improve safety, we placed a steady rest rail on the back of the guide rail, and the steady rest rail supported the third roller of the steady rest metal fitting installed at the rear of the front shelf, so that This is a practical and useful idea that can prevent the back and forth wobbling that occurs when the shelves are moved.
