BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporting and fixing mechanism for a shelf board and other objects requiring supporting and fixing.

[0002]

2. Description of the Related Art In general, movable shelves used for hanging cabinets for kitchens, cupboards, storage furniture, office cabinets and the like are characterized in that their height can be adjusted. This adjustment refers to a mode in which a support dowel is generally changed in the vertical position of a support, and a shelf board is placed thereon. As described above, since it is basically mounted on the support dowel from above, first of all, there is no defense against upward force from below, and there is anxiety that it will come off during strong vibration or careless handling. Remains. In addition, as for the packing form, when it is simply set on a cupboard during transportation or the like, it is dangerous to remove it. Therefore, it is not usually set in a cupboard, and a separate packing material is applied and fixed. Because of these problems, there is a demand for a movable shelf that can be easily fixed and easily adjusted up and down.

The following is a specific description of a conventional shelf board support mode. First, the basic mode of the movable shelf, which has been most frequently used in the past, is to provide a simple concave portion 11 on the edge of the fore edge of the shelf plate 10 as shown in FIG. Is what you do. The embodiment shown in FIG. 13 is a modification or an application of the embodiment shown in FIG. 12, and basically replaces the recess at the front end face of the shelf 10 with the front and rear support dowels 20 with one wide recess 11. . That is, the two supporting dowels 20 are sandwiched between the shelves 10, or the backing plate 30 and the supporting dowels 20 sandwich the shelf 10 to fix the shelf 10 in the front-rear direction. 14 and 15 are somewhat improved. One or both of the two concave portions 11 on the edge of the fore edge of the shelf 10 are irregular concave portions 11, and in the concave portions, a simple upward force is applied. On the other hand, shelves are less likely to come off. However, although the embodiments shown in FIGS. 14 and 15 are improved from those shown in FIGS. 1 and 2, they have almost no effect on complicated vibrations such as transportation and earthquakes. Is the actual situation. Therefore, in any case, the conventional shelf support mechanism is substantially vulnerable to upward force, and is decisively effective against vibration during transportation, earthquakes or careless handling. At present it is not seen.

[0004]

SUMMARY OF THE INVENTION In view of the above situation, the present invention provides a method of easily fixing a member to be supported, for example, a shelf plate, to a support, and removing the same. While retaining the function of a movable shelf that can be freely adjusted, the shelf board does not come off not only against the downward working force but also the front and rear and further upward working force. Provided is a mechanism for supporting and fixing a supported member such as a shelf plate, which is excellent in both convenience and safety without worrying about the detachment of the shelf plate even in the case of shaking or other vibration or careless handling such as jumping up the shelf plate. The task is to
