Description

[Detailed description of the invention] The present invention is equipped with a storage case that is suspended under the floor of a kitchen or the like, and the upper surface of the case can be opened and closed by a lid plate installed on the same plane as the floorboard. , or seasonings such as soy sauce, or foodstuffs such as potatoes in the storage case.

Conventionally, as shown in Japanese Unexamined Utility Model Publication No. 56-176335, a pair of rails are stretched horizontally in parallel under the floor, and a frame body with rollers that is locked from below to the outside of the upper edge of a storage container is slid onto the rails. A plurality of storage containers are movably supported and suspended under the floor so as to be horizontally movable, each storage container is moved below an opening provided in the floor surface, and the storage containers moved below the opening are lifted and lowered. A technology was developed to lift and support it on the floor using a device.

However, in the above-mentioned conventional technology, the frame body that suspends and supports the container moves when the container starts to rise and after the container rises, causing the frame to shift relative to the raised storage container. The container cannot be stably suspended and supported on the frame again, making it difficult to move the storage container smoothly horizontally, and there is a risk that the storage container may fall off the frame during horizontal movement or at the destination. There were some problems.

However, in the present invention, a pair of rails are stretched in parallel in the horizontal direction under the floor, and a receiving arm that is locked from below to the outside of the upper edge of the storage case is slidably supported on the rails via a roller. A plurality of storage cases are suspended and supported under the floor so that they can be horizontally moved, and each storage case is moved to a case lifting position below a single lid plate provided on the same plane as the floorboard. A case lifting device consisting of a guide frame that supports the stand so that it can be raised and lowered, and an electric motor that raises and lowers the pedestal is installed at the case lifting position to lift and support the storage case that has been moved to the case lifting position above the floorboard. In this structure, a leaf spring is provided on the receiving arm supported on one of the rails, and a protrusion is provided on the receiving arm supported on the other rail, so that when the storage case is moved to the case lifting position, the storage case is suspended. The leaf spring of one supporting arm is engaged with a switch for detecting the lifting position of the storage case, and the protrusion of the other receiving arm is engaged with a leaf spring fixed under the floor. This structure is configured to restrict the movement of the storage case, and prevents the receiving arm that suspends and supports the case from shifting its position relative to the raised storage case. The storage case can be stably suspended and supported on the receiving arm, the storage case can be moved horizontally smoothly, and the storage case can be prevented from falling off the receiving arm during the horizontal movement and at the destination.

, lift and lower limit switches 23 and 24 that are attached to the upper and lower ends of the guide frame 14 to detect the lifting and lowering of the lift frame 12, and an opening switch 25 that is attached to the inside of the opening of the floor plate 3 to detect the opening and closing of the cover plate 10. A switch box 26 is provided inside the opening of the floor plate 3, and rise and fall switches 27 and 28 for operating the motor 19 in forward and reverse directions are attached to the box 26. The limit switch 22 is attached to the leaf spring 6a of the receiving arm 6 on one side.
Further, the plate springs 22a of the joist 1 are respectively engaged with the protrusions 6b of the receiving arm 6 on the other side, and the positions of the respective arms 6, 6 are determined.

As shown in FIG. 4, a normally open lifting position limit switch 22 and a normally closed opening switch 25
Raising and lowering switches 27 and 28 are connected in parallel to the power supply 29 of the motor 19 via the
It is equipped with raising and lowering circuits 30 and 31 that rotate the motor 19 in the normal and reverse directions, and connects each of the circuits 30 and 31 in series to the raising and lowering switches 27 and 28 via the raising and lowering limit switches 23 and 24, respectively. When the cover plate 10 is removed and the storage case 7 is moved to the opening of the floor plate 3, the motor 19 is rotated forward and backward by operating the up and down switches 27 and 28, so that the storage case 7 can be moved up and down.

Further, an overload prevention circuit 30a is connected between the switch 23 and the up circuit 30, and a down switch 22a is connected between the switch 23 and the down circuit 31, and an OR circuit 19b is connected to each switch 27, 28. This is to connect the electromagnetic coil 19c for releasing the brake 19a.

The present invention is constructed as described above, and the cover plate 10 fitted into the floor plate 3 is removed, and any one of the plurality of storage cases 7, 7 supported by the rail 4 is placed below the opening of the floor plate 3. Move and raise switch 2
7 is operated to raise the pedestal 11 and lift the storage case 7 above the floorboard 3, and the stored items are taken in and out of the case 7, and the inside of the case 7 is organized and cleaned. On the other hand, the storage case 7 is lowered below the floor by operating the lowering switch 28, and the upper opening of the case 7 is closed by the cover plate 3.

In addition, the receiving arm 6 is brought into contact with the lifting position limit switch 22 to detect the storage case 7 that has moved to the opening of the floor plate 3. is interrupted by the switch 22, so that the storage case 7 can be safely and reliably supported on the receiving arm 6.
The storage case 7 can be easily removed by blocking the motor 1 on the bottom side by removing the pedestal 11.
9 etc. can be easily maintained and repaired, and the cradle 1

a can prevent the motor 19 from being forced upward, and the lowering switch 22a can prevent the lowering of the pedestal 11 by removing the storage case 7, and the lowering and lowering switches 27, 28 In conjunction with this, the brake 19a can be released.

Furthermore, FIG. 5 shows another embodiment in which the rack gear 16 and pinion gear 17 shown in the above embodiment are omitted, a pulley 32 is attached to the upper end of the guide frame 14, and a wire is connected at one end to the lift frame 12. 33 The other end of the winch drum 34 is wound around the winch drum 34 via the pulley 32, and a winch drive box 35, in which the drum 34 is provided, is disposed on the upper surface of the support leg 13, and a winch motor is an elevating member that moves the pedestal 11 up and down. 36 is attached to the box 35, and as in the above embodiment, the winch drum 34 is moved forward and backward by operating the up and down switches 27 and 28, the pedestal 11 is raised and lowered, and the storage case 7 is moved. It is used to lift up the floorboard 3 above to take in and out stored items.

As is clear from the above embodiments, the present invention has a pair of rails 4 stretched horizontally and parallel to each other under the floor, and a receiving arm 6 that is latched from below to the outside of the upper edge of the storage case 7 is moved onto the rails 4. A plurality of storage cases 7 are slidably supported through rings 5 and suspended and supported under the floor so as to be horizontally movable, and each storage case is placed in a case elevating position below a single lid plate 10 provided on the same plane as the floorboard 3. A case elevating device that moves the case 7 and includes a pedestal 11 on which the storage case 7 is placed, a guide frame 14 that supports the pedestal 11 so as to be able to move up and down, and an electric motor 19 that moves the pedestal 11 up and down. In the structure in which the storage case 7, which is placed in the lifting position and moved to the case lifting position, is lifted and supported above the floor plate 3, a leaf spring 6a is attached to the receiving arm 6 supported on the one rail 4, and the leaf spring 6a is attached to the receiving arm 6 supported on the one rail 4. A protrusion 6b is provided on the receiving arm 6 that supports the case, and when the storage case 7 is moved to the case elevating position,
