1 and 2 show an underfloor storage A which is an embodiment of the present invention. In the figure, 1 is a base frame, 2 is a guide frame, and 3 is a storage main body. The base frame 1 is installed between the floor F and the ground G.
The base frame 1 accommodates the guide frame 2 therein and guides its elevation, and is made up of a box-like structure, four pillars, and the like. The guide frame 2 is for accommodating the storage main body 3 therein and guiding its elevation and descent, and is constructed of a box-shaped frame or a frame having four pillars. The storage main body 3 is constituted by a box having an appropriate internal volume capable of storing food, bottles, etc., and is provided with a lid 8.

The guide frame 2 is fitted in sliding contact with a guide surface 4 on the inner surface of the base frame 1 so as to be movable up and down, and the storage main body 3 is fitted in sliding contact with a guide surface 5 on the inner surface of the guide frame 2 so as to be movable up and down. . As shown in FIG. 2, the guide frame 2 and storage main body 3 can be moved up and down smoothly by attaching rollers 6 and 7, respectively, and rolling them on the guide surfaces 4 and 5. This is preferable.

In FIG. 1, 10 is a drive cable for driving the storage main body 3 upward. As clearly shown in FIG. 3, a first cable guide 11 and a second cable guide 12 are provided at the upper and lower ends of the guide frame 2. Further, a third cable guide 13 and a fourth cable guide 14 are provided at the upper end and the lower end of the base frame 1. Note that each of these cable guides 11, 12, 13, 14 is
It may be a guide plate that guides the wiring route while sliding the cable on its surface, or it may be a pulley that guides the cable while rotating. One end of the drive cable 10 is fixed to the lower end of the storage main body 3 with a suitable metal fitting 15, and the middle part of the drive cable 10 is attached to the first cable guide 11, the second cable guide 12, the third cable guide 13, and the third cable guide 13. The four cable guides 14 are connected in this order, and the other end is connected to a cable drive device 20. Note that as the drive cable 10, any cable such as a suitable rope or steel cable can be used as long as it can withstand the lifting load of the storage main body 3. The cable drive device 20 may be of any type as long as it can drive the drive cable 10 to be fed out and retracted. For example, the cable drive device 20 may include a winding drum 22 that is rotated in forward and reverse directions by an electric motor 21. In addition, the drive cable 1 routed as described above
In order to smooth the vertical movement of the storage main body 3 and the guide frame 2, it is preferable that at least two wires 0 are arranged symmetrically, or four wires are arranged at each of the four corners of the storage main body 3 and the guide frame 2. Preferably, each drive cable 10 is guided by a cable guide located at a suitable location and driven by a single cable drive device 20.

Next, as mentioned above, the ascending drive cable 10

Since the guide frame 2 and the storage cabinet body 3 have a two-stage telescopic structure, the lifting stroke is large and the storage cabinet body 3 can be lifted to a sufficient height, making it possible to take out stored items without having to bend down. becomes very easy.

For the lowering operation, it is sufficient to reverse the electric motor 22, in which case the drive cable 10 is let out,
The storage main body 3 and the guide frame 2 descend due to their own weight. When the guide frame 2 is completely lowered into the base frame 1 and the storage main body 3 is completely lowered into the guide frame 2, the upper surface of the storage main body 3 and the floor are flush with each other, as shown in FIG. By covering it with the lid 8, it becomes flat and a person can walk on it.

Next, based on Figure 5, one drive cable 1
Embodiment B in which both sides of the storage main body 3 are simultaneously driven up and down at 0 will be described.

This has almost the same configuration as the underfloor storage A shown in Figs. 1 to 3, but fifth cable guides 16a and 16b are provided at the lower end of the storage main body 3, and the left and right drive cables 10 are connected to each other. They are connected to each other via fifth cable guides 16a and 16b. Note that the connection between the drive cable 10 and the storage main body 3 in the present invention includes such a mode. One end of the drive cable 10 is attached to the upper end of the base frame 1 on the opposite side of the base frame 1 from the cable drive device 20 (the right side in FIG. 5) with a stopper fitting 1.

6b, the first cable guide 11b, the second cable guide 12b, the third cable guide 13b, and the fourth cable guide 14, and the other end is connected to the cable drive device 20.

In this embodiment B, the amount of payout and retraction of the drive cable 10 is twice the lifting stroke of the storage main body 3, but the winding torque is halved, and moreover, the amount of drive of the left and right cables is automatically synchronized. It has the advantage of being done.

In addition, one set each of the cable drive devices 20 shown in FIG. 5 are installed in two locations on the front side and the back side in the drawing of the underfloor storage B so that they are parallel to each other, as in the case of the previous embodiment. , the four corners of the storage main body 3 may be driven up and down simultaneously.

Furthermore, in such a case, as shown in FIG. 6, the drive cable 10 on the front side and the drive cable 10 on the back side of the underfloor storage B are driven by separate cable drive devices 20a and 20b, respectively. Alternatively, as shown in FIG. 7, two drive cables 10 may be guided by a cable guide 17 and wound and driven by one cable drive device 20. In the case of the configuration shown in FIG. 7, only one cable drive device 20 is required, which has the advantage of simplifying the device.
Note that this configuration can also be adopted in Embodiment A shown in FIG.

Next, referring to FIG. 8, a description will be given of Embodiment C in which the lowering operation is not based on the body's own weight but is driven by a cable. In the same figure, the chain line indicates the drive cable 10 for ascending,

The other end is attached to the winding drum 22. Note that, like the ascending drive cables 10, the descending drive cables 30 are symmetrically arranged in two or four cables, and the same ropes or steel cables are used. The drive cable 30 is wound around the winding drum 22 in the opposite direction to the winding of the drive cable 10, and when the winding drum 22 is rotated forward, the driving cable 10 for ascending is wound up. The lowering drive cable 30 is let out,
When the winding drum 22 is reversed, the upward driving cable 10 is unwound and the downward driving cable 30 is wound up. In this embodiment as well, the drive cables 10 and 30 are arranged on the front side and the back side of the underfloor storage C, respectively, and the cable guides 17 are arranged as shown in FIG. It is also possible to drive it with a cable drive device 20.

However, the underfloor storage C configured in this way
In this case, not only the upward movement but also the downward movement can be driven by power, so that the movement is reliable.

Next, another example of the cable drive device will be explained based on FIG. 9. This drive device 40 includes a long threaded rod 42 rotated by an electric motor 41, and a block 43 that spirals on the threaded rod 42, and the drive cables 10, 30 are attached to the block 43. It is. In this device 40, block 43
reciprocates with a stroke of the length of the threaded rod 42, thereby allowing the ascending drive cable 10 and the descending drive cable 30 to be paid out and retracted.

Note that if the underfloor storage is installed in a building that is already equipped with a pneumatic source or a hydraulic source, a wire cylinder may be used as the cable drive device.

Although the embodiments of the present invention have been described above, various modifications can be made to the present invention without departing from the gist thereof.
