Description

  The present invention relates to an elevating type mounting shelf that can be used in combination with a hanging cabinet that is a part of a system stocker of a kitchen, for example.

  2. Description of the Related Art Conventionally, on a wall surface or the like above a cabinet in a system kitchen, a hanging cabinet for storing objects such as cooking utensils, fixtures, and foodstuffs around the kitchen is provided. Although it is very convenient if the hanging cabinet is provided with an elevating type mounting shelf that is used only when necessary, the present situation is that such a member is not provided.

On the other hand, as a work shelf provided in a factory line, an elevating shelf device as shown in Patent Document 1 is considered. This lifting shelf device is configured such that the work shelf is biased upward by a spring.
When such a configuration is applied to a kitchen mounting shelf, it is required that the urging force of a spring for lifting the mounting shelf be constant at any position in the lifting range. That is, when the urging force of the spring is increased near the lower limit position of the mounting shelf in order to lower the mounting shelf relatively frequently, a large force is required to lower the mounting table, and the usability becomes extremely bad. . Further, when raising the mounting table, the mounting shelf rises vigorously near the lower limit position, which is dangerous.
Therefore, a constant load spring that is almost custom-made is used. However, if constant load springs are provided for each size of the mounting shelf, there is a problem that the component cost increases.

Moreover, since the raising / lowering shelf apparatus of patent document 1 is provided in the simple suspending state, a backlash may arise in a horizontal direction during use.
Furthermore, when the shelf board is manufactured by combining a plurality of members, most of them use screwing, and it takes time to assemble.
Further, when the weight of the object to be placed is heavy, it is necessary to increase the mechanical strength of the shelf board. However, there is a limit only by devising the structure of only the shelf board.

JP 2002-369720 A

  The present invention has been made in view of the existence of such problems in the background art, and can be used for shelves of various sizes without replacing constant load springs. There is no backlash of the board, it can be installed using a narrow space such as an unused space on the back of the storage cabinet, and the shelf board is easy to assemble, and the shelf board made of inexpensive materials is used to increase the mechanical strength of the shelf board. It is an object of the present invention to provide a liftable mounting shelf that can be used.
