BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric underfloor storage attached to the floor of a kitchen or the like, and more particularly to an electric underfloor storage that can be used selectively by horizontally moving a plurality of storage cases.

0002

[Background technology and its problems] Parallel horizontal guide rails are arranged on the left and right sides of an opening provided on the floor of a kitchen, etc., and a case support mechanism that supports a pair of storage cases in front and behind the horizontal guide rail is movably loaded. However, the present applicant has already proposed an electric underfloor storage (storage object moving device) in which each storage case can be selectively placed below the opening using a drive device (see Utility Application No. 1-118482). ).

By the way, in this type of electric underfloor storage, a pair of storage cases connected front and back move along a horizontal guide rail and are selectively positioned below the opening, so the length of the horizontal guide rail is limited. Requires three times the width of at least one storage case in the front and back direction.

[0004] For this reason, the horizontal guide rails have a considerable length, which takes up space in storage and transportation, resulting in inefficiency and increased costs. In particular, in the case of electric underfloor storage that includes a lifting drive device that raises and lowers the storage case and a lid opening/closing mechanism linked to the device, each mechanism is organically arranged in a rectangular parallelepiped main body frame and integrated. Therefore, the horizontal guide rail also needs to be assembled integrally with the main body frame, which results in a significant increase in the size of the electric underfloor storage as a whole, which not only causes problems in storage and transportation, but also There were problems with construction that were extremely difficult.

[0005] The present invention solves the problems that exist in the background art, and saves space during storage and transportation through a rational unit configuration of each part.
The objective is to provide an electric underfloor storage that can significantly improve storage and transportability, as well as simplify installation.

[0006]

[Means for Solving the Problems] In the present invention, horizontal guide rails 2, 2 are arranged on the left and right sides of an opening S provided in the floor F, and a plurality of storage cases 3x,
The case support mechanism 4 supporting the 3y is movably loaded,
When configuring the electric underfloor storage 1 in which the storage cases 3x and 3y can be selectively arranged below the opening S, the storage cases 3x and 3y are particularly designed to be insertable from above into the opening S. It is equipped with a main body frame 5 provided with an elevating drive device 6 for elevating the 3x or 3y, and a horizontal guide rail 2.
, 2 to front rail parts 2f, 2f, intermediate rail parts 2m, 2m
And divided into rear rail part 2r, 2r, middle rail part 2m
... is attached to the main body frame 5, and the front rail portion 2f... and the rear rail portion 2r... are configured to be attachable to the floor component Fc under the floor, and the case support mechanism 4 is attached to each storage case 3.
A horizontal movement drive device 8 is configured of a plurality of case support frames 7x and 7y that correspond to the case support frames 7x and 3y and can be connected to each other, and horizontally moves the case support frame 7x (7y) to one case support frame 7x. It is characterized by having been provided. In this case, the horizontal movement drive device 8 is moved forward and backward by a drive unit 9 attached to the case support frame 7x, and one end 10p is coupled to the case support frame 7x, and the other end 10q is connected to the floor F side. The geared wire 10 can be configured to include a geared wire 10 coupled to a fixing member 11 that is fixed to the fixing member 11.

[0007]

[Function] According to the electric underfloor storage 1 according to the present invention, the floor F
The horizontal guide rail 2 placed on the bottom side of... is the front rail part 2
f..., intermediate rail part 2m..., and rear rail part 2r..., so the length of each rail part 2f..., 2m..., 2r... is approximately 1/3 of the total length. Therefore, the front rail portion 2f
... and the rear rail portions 2r... can be attached in advance to the floor component Fc under the floor, and only the intermediate rail portions 2m... can be attached to the main body frame 5. In this case, since the intermediate rail portion 2m (the other one is the same) is integrally assembled to the main body frame 5, the positional relationship is accurately set. Moreover, since the main body frame 5 is configured to be inserted into the opening S from above, it is inserted into the opening S from above the floor F at the time of installation, and is attached to the floor component Fc. As a result, the intermediate rail portion 2m is continuous with the front rail portion 2f and the rear rail portion 2r, forming the original horizontal guide rail 2 that is linearly integrated.

Furthermore, since the case support mechanism 4 is composed of a plurality of case support frames 7x and 7y that correspond to each storage case 3x and 3y and can be connected to each other,
The case support frames 7x and 7y can be sequentially accommodated in the opening S and loaded onto the horizontal guide rails 2, and the case support frames 7x and 7y can be connected to each other after being loaded. In this case, one case support frame 7x has a horizontal movement drive device 8 for horizontally moving the case support frame 7x (7y), that is, a drive section 9 attached to the case support frame 7x, and the drive section 9 moves the case support frame 7x (7y) forward and backward. At the same time, since a horizontal movement drive device 8 is provided which includes a geared wire 10 whose one end 10p is connected to the case support frame 7x and whose other end 10q is connected to a fixing member 11 that is fixed to the floor F side, the case support frame 7x After loading the wires onto the horizontal guide rails 2 . Since the other end 10q of the geared wire 10 is fixed to the floor F side, one end 10p
The case support frame 7x to which it is connected is relatively moved along the horizontal guide rail 2.

Therefore, by controlling the operation of the horizontal movement drive device 8, the storage cases 3x and 3y supported by the case support frames 7x and 7y can be selectively placed below the opening S. On the other hand, by controlling the operation of the lifting drive device 6 provided on the main body frame 5, the storage case 3x or 3y located below the opening S can be moved up and down.
