Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to an elevating shelf installed on the upper part of an indoor wall.

B. Prior art The structure of the elevating shelf that raises and lowers a part of the hanging cabinet is one that uses a pulley and a balance weight, and one that uses a gas damper to move it (Japanese Patent Application Laid-Open No. 62-2011).
275410), or a device that hangs on a stopper, etc. at the raised and lowered positions of the elevating shelf (Japanese Utility Model Application No. 62-70828, Utility Model Application No. 62-111439)
It was hot.

C. Purpose of the invention or problem to be solved by the invention A device using a pulley and a balance weight has the disadvantage that extra space is required for the pulley and the weight, which reduces the amount of storage space. Those using dampers had the disadvantage of having a complicated structure and requiring less storage space.

Also, Publication No. 70828 of Utility Model Application Publication No. 1987-
The device disclosed in Publication No. 111439 cannot freely and reliably stop the elevating shelf at an intermediate position between the upper and lower positions.

D. Structure of the invention or means for solving problems In the invention, an elevating shelf that moves up and down along a drawer rail is suspended from above by constant force springs, and a stopper is attached to a rack gear fixed along the drawer rail. The locking end of the rack is releasably locked so that the elevating shelf can be reliably stopped at any position.

To explain the embodiment of the present invention with reference to the figure, the elevating shelf 1 consists of a board 2, a storage shelf 5, and a back plate 4 with a constant force spring 11 arranged at the upper end.
is supported by a thick U-shaped frame 3, both edges of which are irremovably fixed to the base plate 2, and the lower end of which protrudes below the lifting shelf 1 and has a grip handle 6.
is doing.

The article storage shelf 5 has an angle 7 open in the usage direction fixed to the frame 3 by welding or the like or removably attached, and moves together with the substrate 2.

The board 2 is fixed to one rail 8-a of the drawer rails 8 via a coupling plate 2-a, and the other rail 8-b is fixed to the back plate 4.

Further, the tip of a constant force spring 9 fixed to the upper end of the back plate 4 is fixed to the upper end of the base plate 2, and works to constantly pull up the elevating shelf 1.

Next, in the stopper mechanism according to the embodiment of the present invention shown in FIGS. Locking end 12-a of
is pressed by a coil spring 13 so as to be constantly engaged, and the other end of the stopper 12 is pivoted to both open ends of a U-shaped stopper handle 10, and the stopper handle 10 is connected to the grip handle 6. The grip handle 6 and the stopper handle 10 are located at a distance such that the grip handle 6 and the stopper handle 10 can be gripped at the same time.

5 and 6 show an embodiment of the present invention, in which the elevating shelf 1 is vertically attached to the center of the inner wall of the hanging cabinet 14 via the back plate 4, and the elevating shelf 1
4 is shown, and FIG. 6 shows the state when it is pulled out from the hanging cabinet 14.

The tensile strength of the constant force spring 9 is 2 kg to 3 kg higher than the expected weight of the elevating shelf 1 when the stored items are stored.
It will be easier to operate if the kg is set large.

E. Function Since the elevating shelf 1 of the present invention is constructed as shown in the drawings and the above explanation, the grip handle 6
By squeezing the and stopper handle 10 together, the stopper handle 10 is pushed up, the locking end 12-a of the stopper 12 is disengaged from the teeth 11-a of the rack gear 11, and the elevating shelf 1 slides up and down. It becomes possible to move.

At this time, since the constant force spring 9 is always working in the direction of pulling up the elevating shelf 1, the elevating shelf 1 is in this state.
When raised and lowered, the elevating shelf 1 moves up and down lightly along the drawer rail 8.

Furthermore, when the hand gripping the stopper handle 10 is loosened or released, the coil spring 13 rebounds the stopper 12, the stopper 12 returns to its original position, and the elevating shelf 1 is reliably stopped at that position. .

F. Effect Since the present invention is constructed and operates as described above, the vertical movement of the lifting shelf 1 is extremely light and smooth, and since both edges of the frame 3 are fixed to the base plate 2, the lifting shelf 1 It is convenient to use because the stopper 12 allows the lifting shelf 1 to be stopped at any position without swinging to the left or right during movement.

In addition, by gripping the grip handle 6 and the stopper handle 10 together or releasing them, the stopper 12 can be automatically engaged and detached, so no special care is required for use, and there is no need to worry about accidentally lifting or lowering the shelf. 1 will not fall and damage property.
