Description

[Detailed description of the invention] [Industrial application field] This invention is a hanging cabinet, etc., which can be freely moved and stopped at a desired height, such as those found in residential or commercial kitchen equipment. This invention relates to an arbitrary height adjustment device.

[Prior Art] Hanging cabinets are widely used as storage for residential or commercial kitchen equipment. Although this equipment is particularly effective in making effective use of narrow spaces, the problem is that it is inconvenient to put in and take out stored items because its height is inevitably higher than human height. It was hot.

[Problems to be solved by the invention] It is clear that the effectiveness of the cabinet would be further increased if it were possible to move the cabinet to a height that makes it easier to take in and take out stored items.

The purpose of this invention is to provide a relatively simple device that allows a hanging cabinet to be placed at an arbitrary height and that can be easily returned to its original position after the work of taking in and taking out stored items is completed.

In addition, even if there is a difference in weight between the main body of the hanging cabinet and the items stored, the main body of the cabinet is equipped with a constant tension device.
The remaining weight is driven by a motor and wires, and the aim is to provide a device that allows smooth height adjustment within the rated range.

[Means for Solving the Problems] The configuration of this invention to solve the above problems includes a hanging cabinet or the like that is mounted so as to be movable up and down along a guide rail provided on a building or a fixed frame;
A constant tension device is fixed at one end to this hanging cabinet, etc., and the other end is fixed to the building or fixed frame directly above this hanging cabinet, etc., and the tensile load of the constant tension device is approximately equal to the tare weight of the hanging cabinet bag, etc. Equally, the hanging cabinet and a hoisting device driven by a small small power motor are connected to each other by a wire through a pulley placed on a fixed frame, and the power of the small small power motor is applied to the hanging cabinet, etc. This is an arbitrary height adjustment device for hanging cabinets, etc. that moves the items stored in the cabinet up and down.

In order to always raise and lower the hanging cabinet horizontally, it is appropriate to connect the wire to the hanging cabinet via a pulley.

A specific example of the apparatus of this invention will be described with reference to the drawings. FIG. 1 is a front view of the apparatus of this invention when the hanging cabinet is lowered. Figure 2 is a side view of the device of this invention; Figure 2-a is its side view;
Figure b is a side view of the hanging cabinet when it is raised. FIG. 3 is a drawing of an example in which the mechanism section is shown with the hanging cabinet omitted.

As shown in the drawing, there are guide rails 4 on both sides of the fixed frame 1, and these guide rails are 4-a, 4-
The cabinet 6 is made up of three parts, b and 4-c, and both ends of the cabinet 6 are fixed to 4-c via bolts and nuts.

There is a cantilever beam 1-a on the upper part of the fixed frame 1, and this cantilever beam 1-a supports a beam 1-b on which a constant tension device 2 is attached. This beam is made of a square tube, and a pulley 7 for changing the direction of the wire 5 for hoisting the cupboard is attached inside the beam.

The wire 5 connects the hanging cabinet 6 and the hoisting device 8 to a pulley 7 placed on the beam 1-b at the top of the fixing frame 1.
The hanging cabinet 6 is rolled up and rewound by a winding device 8. To explain the operation of this wire 5, since the wire 5 is wound in two strips, the length of the wire 5 equivalent to the height when the hanging cabinet 6 is raised is wound around the winding device. Moreover, when the hanging cabinet 6 is lowered, the situation is reversed.

If the load of this constant tension device is balanced with the weight of the cabinet body, and the variable load caused by the items stored in the cabinet is handled by the hoisting device 8 driven by the small motor 3, the lifting device can be lifted with relatively small power. The cupboard 6 can be placed at an arbitrary height or moved.

In the above example, the constant tension device 2 is attached to the cantilever beam 1-a and connected to the hanging cabinet 6, and the wire 5 is connected to the hoisting device 8 via the hanging cabinet 6 and the pulley 7 of the cantilever beam 1-a.
However, it goes without saying that an elevating frame may be provided in place of the guide rail 4-c separately from the fixed frame 1, and a cupboard or the like may be placed and fixed on this elevating frame.

Further, this arbitrary height adjustment device is not limited to a hanging cabinet, but can also be used as a height adjustment or lifting device for desks, tables, various machines, devices, etc., for example.

[Effects of the invention] As explained above, with the device of this invention,
The load of the constant tension device is balanced with the weight of the hanging cabinet body, so if there are no items stored, the hanging cabinet can be left in any vertical position. Furthermore, when items are stored in a hanging cabinet, the weight of the items is lifted by the force of the motor, which saves labor and makes it easier to handle and store equipment.
