Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to raising and lowering the shelf portion of a hanging cabinet attached to the upper part of a wall surface in a kitchen or the like.

[Conventional technology]

BACKGROUND ART Conventionally, a hanging cabinet has been installed at the upper part of a wall to utilize the upper space as a storage space for items in a kitchen or the like. We also designed the shelves to be able to be raised and lowered, taking into consideration the workability of loading and unloading items onto the shelves of the hanging cabinets.
! There have been attempts to raise and lower the shelf, particularly to lift the shelf, using a driving device such as an M-movement motor.

One of them has a configuration in which the touch switch connected to the drive device is a non-locking type, and the drive device operates only while the touch switch is held down, and stops operating when the touch switch is released. There is something. In addition, there have been devices in which the touch switch connected to the driving device is of a locking type, and the driving device is activated simply by pressing the touch switch, and released by pressing another stop switch or the like.

[Problem that the invention seeks to solve]

However, among the conventional configurations mentioned above, especially those using locking touch switches,
Since the driving equipment continues to operate until the shelf reaches top dead center, it is dangerous if a finger gets caught, and if a non-locking touch switch is used, the shelf The problem was that the touch switch had to be pressed and pressed until the lift was completed, resulting in poor operability of the drive equipment.

[Means for solving problems]

The present invention has been made in consideration of the above-mentioned conventional problems, and includes a lifting part that raises and lowers the shelf part of a hanging cabinet through a drive device such as an electric motor, and a lifting part that is connected to the lifting part and closes only when pressed. It consists of a control section that is equipped with a touch switch and switches the operation of the elevating section, such as raising and lowering the shelf, and the control section controls the raising and lowering of the elevating section when the shelf is located at a specific point within the elevating range of the shelf. Provided is a lifting device for a hanging cabinet, comprising a stopping means for stopping the operation, and a holding means for holding the lifting operation of the lifting portion from the specific point to the top dead center only when the touch switch is turned on. This solves the conventional problems.

[For production]

In the present invention, the shelf located at the bottom dead center is located at a specific point in the vertical range from the bottom dead center, for example, from the bottom of the hanging cabinet to the
Make sure that the shelf does not rise unless it rises to a position of ~10z and stops, and then continues to press the touch switch, and when the shelf rises, continue to press the touch switch during the stopping process and after this stopping process. The rising process is formed by

〔Example〕

Next, the present invention will be explained in detail based on the embodiments shown in FIGS. 1 to 3.

A in the diagram is a hanging cabinet installed at the top of a wall in a kitchen, etc.
A storage section B whose bottom surface is open is formed in a part of the hanging cabinet A, and a plurality of shelves or a shelf section C equipped with electric appliances is stored in the storage section B. This shelf C is supported by a lifting device which will be described later, and when the lifting device operates, the shelf C containing dishes, small bottles, etc. is raised and lowered.

In the figure, reference numeral 1 denotes a lifting device for lifting and lowering the shelf C, and this lifting unit @1 comprises a lifting unit 2 and a control unit 3, as shown in FIG.

The lifting section 2 includes a driving device 20 such as an electric motor installed inside the hanging cabinet A, and this driving device 20 supports the shelf section C via a coupling device (not shown) such as a gear or a belt. , the shelf C is provided so as to move up and down as the drive device 20 operates.

The control section 3 is connected to the elevating section 2, and the elevating section 2 is operated by operating the control section 3, and the shelf C is raised and lowered. That is, the control unit 3 is provided with a switch for raising and a switch for lowering in the operating circuit of the lifting unit 2, and when the switch is pressed to close the circuit, electricity is supplied to the lifting unit 2 side, and the driving vJ equipment 20 is energized. is activated to move the shelf C up and down.

FIG. 3 is an explanatory diagram showing the operation of the 1111 part 3. In the figure, 30 is a touch switch for lowering, 31 is a touch switch for raising, and 4 is a lower limit switch that is turned off when the shelf is located at the bottom dead center. , 5 is an intermediate limit switch that is turned off when the shelf is located at a specific point set several centimeters from the top dead center, 6 is an upper limit switch that is turned off when the shelf is located at the top dead center, and 7. 8.9 is a relay.

When a shelf located at bottom dead center a is raised (in addition,
Intermediate limit switch 5 and upper limit switch 6 are closed), and the coils of relays 7 and 9 are not energized, so the contacts of relays 7 and 9 are 70.90
is closed (contacts 70° and 90 are normally closed), and by pressing the touch switch 31, the relay 8
is energized, the coil is energized, the contact 80 (normal oven) of the relay 8 is closed and self-maintained, and the elevating section 2 is energized and the shelf begins to rise.

When the ascending shelf reaches a specific point, the limit switch 5 opens halfway, releases the self-holding of the relay 8, and lifts the ascending/descending section 2.
The shelf section stops by stopping power supply to the shelf. In this way, by stopping the shelf section before storing it in the storage section, it is possible to prevent accidents such as fingertips being caught or rising with stored items sticking out.

After checking to see if your fingertips have been caught or if the stored items have been removed,
By continuing to press the touch switch 31 again, the shelf begins to rise (at this point, the halfway limit switch 5 is open). i.e. relay 7 and relay 8
Since the coil is not energized, the contact 70.81 (contact 81 is normally closed) and the upper limit switch 6 are closed, and by continuing to press the touch switch 31, the shelf C reaches the top dead center C. The elevating section 2 is energized until the upper limit switch 6 is opened. At this point, after the coil of the relay 9 is energized and the normally closed contact 90 is opened, the limit switch 5 is provided to close midway.

When lowering the shelf stored in the storage section, since the coil of relay 8 is not excited, the normally closed contact 81 is closed, the lower limit switch 4 is closed, and the lower limit switch 4 is closed. By pressing the switch 30, the relay 7 is energized, the coil of the relay 7 is energized, and the contact 71 of the relay 7 is closed and self-holding.
The shelf C is provided to descend until the shelf C reaches the bottom dead center a, the lower limit switch 4 is opened, and the self-holding of the relay 7 is released.

As mentioned above, when the shelf C has already stopped at a specific point and needs to be lowered again, the limit switch 5
Since it is open, the shelf C can be lowered simply by pressing the touch switch 30. In the figure, d is a fuse, and e is a power switch.

〔Effect of the invention〕

As explained above, according to the present invention, the shelf part is raised and lowered by an elevating part that raises and lowers the shelf part of the hanging cabinet via a drive device such as an electric motor, and a switch that is connected to the elevating part and closes only when the shelf part is suppressed. a control section for switching the operation of the elevating section, such as lifting and lowering; Since it is provided with a holding means that holds the lifting operation of the lifting section from a specific point to the top dead center only when the switch is turned on, the shelf section is temporarily stopped before being stored, and then the shelf section is moved while pressing the switch. This has excellent practical effects, such as being able to check if stored items are being taken out or if a finger is caught, and it is possible to prevent malfunctions and accidents in the 4-way elevator.
