Such a moving device 1, that is, each of the moving units Ma and Mb can be retrofitted by modifying an existing fixed underfloor storage, and since a pair of the same unit can be prepared, it is advantageous in terms of cost. In addition, since it can be transported in a compactly disassembled state, it is easy to handle.

Therefore, when the drive motor 11 is operated and the worm gear 12 is rotated in the forward direction, the worm wheel 13 is decelerated and rotated, and the pinion 41 is further rotated. As a result, the pinion
The sector gear 8 meshing with 41 rotates about the fixed support shaft 9 and displaces one end of the main arm 4 upward, whereby the movable rail 6, and further the sliders 36a and 36b ascend along the guide rails 35a and 35b. Let Therefore, the storage case Cs supported by the support frames 43a and 43b can be raised above the floor surface 21 as indicated by a virtual line Cso in FIG. On the other hand, when the drive motor 11 is operated in the reverse direction, the transmission gear mechanism 14 and the main arm 4 rotate in the reverse directions, respectively, and the storage case Cs descends below the floor surface 21 as shown by the solid line in FIG. To do. The position control of the ascending position or the descending position can utilize a limit switch or a numerical control of a stepping motor. Further, it is desirable to provide a link mechanism for automatically opening and closing the lid 22 in conjunction with the raising and lowering operation of the storage case Cs.

Although the first embodiment has illustrated a single storage case Cs,
Two stations (generally multiple stations) as in the modification shown in FIG.
The same can be applied to the storage cases Cs-1 and Cs-2. In this case, below the floor surface 21, parallel horizontal rails 51 are provided along the floor surface 21, and the horizontal rails 51 ...
The case holders 52 and 53 for holding Cs-1 are slidably attached. Incidentally, the storage case Cs-1 ... is a case holding portion.
It can be displaced upward with respect to 52. Further, geared wires 54 are coupled to one case holding portion 53, and the geared wires 54 are moved forward and backward by a drive mechanism portion 55 including a transmission gear mechanism and a drive motor. Therefore, the storage cases Cs-1 and Cs-2 can be selectively arranged below the opening 23 by controlling the operation of the drive mechanism 55. Further, the storage cases Cs-1 ... Arranged below the opening 23 can be moved up and down by the moving device 1 similar to the first embodiment.

Second Embodiment Next, a second embodiment in which the moving device is used as a hanging cabinet will be described with reference to FIG.

The hanging cabinet B is placed on the wall surface of the kitchen in the house, and as shown in FIG. 6, one moving unit Ma is fixed to the wall surface by the mounting brackets 71a and 71b, and the protruding connecting piece 37.
The upper ends of the storage shelves Ct may be directly fixed to the a and 37b by the mounting brackets 72a and 72b. In addition, storage shelf Ct
