Description

  The present invention relates to an elevating type cupboard which has a simple structure and smoothly lifts and lowers a storage shelf housed in a cupboard case, and makes it easy to take out and store items in the cupboard.

The conventional cupboard is installed on the wall surface above the sink, etc., and it can be moved up and down by moving the storage shelf stored in the cupboard case with the bottom open by winding and rewinding the belt by motor drive There is a cupboard (see, for example, Patent Document 1).
In addition, the conventional cupboard is installed on the wall surface above the sink, etc., and the belt is wound up and rewound by driving the motor to raise and lower the storage shelf stored in the cupboard case with the bottom open, There is also a lift cabinet that can be pulled out diagonally forward when it is lowered (see, for example, Patent Document 2).
However, the conventional elevating cabinet that allows the cabinet stored in the cabinet case to be moved up and down can be easily taken out and stored when the storage shelf is lowered, but extends to the left and right ends respectively. Since it requires a lifting device that winds and unwinds two belts, it is complicated, and in order to smoothly lift and lower the storage shelf, there are a plurality of spaces between the inside of the cupboard case and the outside of the storage shelf. It requires a complicated slide rail with a bearing.
In addition, a slide rail is provided diagonally forward between the inside of the cupboard case and the outside of the storage shelf, and the cupboard can be lifted diagonally forward by the same lift drive mechanism, but the lifting device is also complicated. Moreover, in order to smoothly lift and lower the storage shelf, a complicated slide rail is required between the inside of the cupboard case and the outside of the storage shelf.
In addition, by retracting and rewinding the belt by driving the motor, the storage shelf to be stored in the cabinet case can be raised and lowered, and when the storage shelf is lowered, the conventional lifting cabinet that can be pulled out diagonally forward is also taken out. However, the lifting device that winds and unwinds the belt provided on each of the left and right ends is complicated. A complicated slide rail is required between the inside and the outside of the storage shelf.
