Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevated drawer device for an elevated storage cabinet or the like, which makes it possible to effectively utilize empty space near the ceiling.

[Conventional technology]

In conventional high storage cabinets, etc., which effectively utilize the area close to the ceiling in the room, in order to put items in and out of drawers located at high places, it is necessary to
It is necessary to use a footrest etc.

[The problem that the idea aims to solve]

Therefore, it is not only dangerous but also troublesome to take articles into and out of conventional high-place storages.

[Means to solve the problem]

According to the present invention, a casing, a drawer housed in the casing with a spring biased toward the rear, a vertical support plate protruding forward on both sides of the casing, and a rear end fixed to the drawer; and a wire rope whose front end descends through the front part of the support plate and is fixed to the knob lever, and a wire rope which is bored through the support plate and has a locking part at the lower end of the vertical part, and the handle lever. The above-mentioned problems can be solved by providing a guide hole into which the support plate is slidably fitted, an elevating rail provided on the support plate, and means for elevating the elevating rail.

〔Example〕

Reference numeral 1 in FIG. 1 denotes an elevated storage cabinet, and a plurality of drawers 4 are housed behind double doors 3, 3 in an upper case 2 of the high storage cabinet. Note that the double doors 3, 3 form vertical support plates, and may be of a fixed type.

The present invention makes it possible to easily pull out or retract the top drawer 4 or the drawer 4 following it, which is located near the ceiling and cannot be pulled out without using a footrest or the like.

As shown in FIG. 2, a plurality of fixed rails 5, 5 are attached to opposite side surfaces of the upper case 2, corresponding to each drawer 4 and forming pairs on the left and right.

A vertical guide groove 6 is provided on the rear surface of the left and right doors 3, and within the guide groove 6 is a guide block 8 that is integrated with a lifting rail 7 that runs along the inner surface of the door 3.
They are slidably fitted.

As shown in FIGS. 2 and 3, a motor 10 with a reduction gear 9 and a reduction gear 9
A drive shaft 11 extending from left to right is attached.

A pulley 12 is fixed to the tip of each drive shaft 11, the front end is fixed to each guide block 8, and left and right wire ropes 14 are pulled out rearward via a guide pulley 13 provided at the upper end inside the guide groove 6. are each wound around the pulley 12 several times and then pulled out downward.

The lower end of each wire rope 14 is connected to a plate-shaped balance weight 1 that hangs down along the entire rear wall of the housing 2.
It is fixed to the left and right upper corners of 5.

In this way, when the motor 10 is driven, the wire rope 14 is wound up and the lifting rail 7 rises, and by an appropriate stopping mechanism (not shown), the lifting rail 7 is stopped just before the uppermost fixed rail 5.
It is now possible to stop in line with this.

A support tube 16 made of a square tube facing the front-rear direction is fixed to the upper inner surface of the left and right side walls of the housing 2.
The sliding tube 17 is properly fitted.

At the front end of the sliding tube 17, there is a continuous piece 18a facing inward.
A locking piece 1 facing inward with a downward-slanted cross section
8 is fixed, and this locking piece 18 is fitted and locked to the upper edge of the entire surface plate of the upper drawer 4.

Between the front end of the sliding tube 17 and the rear wall of the housing 2,
A tension spring 19 is tensioned, and the sliding tube 17 is always urged to pull into the support tube 16.

A vertically long guide hole 20 is bored near the free end of the rear surface of the door 3, extending vertically downward from slightly below the uppermost lifting rail 7, and having a lower end horizontally bent 20a facing forward. There is.

The tip of the knob lever 21 is slidably fitted into the guide hole 20, and the rear end of the royal rope 22, whose front end is fixed to the knob lever 21, is inserted into the guide hole 20.
It is fixed to the front end of the sliding tube 17 via a guide pulley 23 fixed to the rear surface of the door 3 above (see FIG. 4).

Wheels 24, 2 are installed at the front and rear of the bottom of both sides of the drawer 4.
4 is installed.

When the door 3 is opened forward, it can be stopped at a right angle by a bifold stay 25.

When the drawer 4 is stored, the sliding tube 1
7 is retracted into the support tube 16 by a tension spring 19, and a knob lever 21 connected to a wire rope 22 is located at the upper part of the guide hole 20. Further, the wire rope 14 is wound up by the motor 10, so that the elevating rail 7 has the same height as the uppermost fixed rail 5.

After opening the door 3, when the knob lever 21 is lowered, the drawer 4 together with the sliding tube 17 is pulled out forward against the tension spring and rides on the elevating rail 7.

After the drawer 4 is completely transferred to the lifting rail 7, the knob lever 21 is locked to the bent portion 20a at the lower end of the guide hole 20, as shown in the fifth figure.

Next, rotate the motor 10 to move the elevator rail 7
When the drawer 4 is lowered along the guide groove 6, the drawer 4 is disengaged from the locking piece 18 and lowered together, making it easy to take articles in and out of the drawer 4.

The storage of the drawer 4 is performed in the reverse order to the above.

When the present invention is applied to multiple drawers 4 in the upper part, a support tube 16, a sliding tube 17, a wire rope 22, and a guide hole 20 are provided for each drawer 4, and a lifting rail 7 is provided. It is sufficient if it can be stopped just before the fixed rail 5 of each stage.

Although the balance weight 15 does not necessarily need to be provided, if it is provided, the capacity of the motor 10 can be reduced and the operation can be made smoother.

Instead of the door in the embodiment, fixed vertical support plates protruding forward on both sides of the casing may be provided and used to implement the present invention.

[Effect of idea]

A drawer located at a high place that cannot be reached can be taken in and taken out or raised and lowered by a simple operation, and articles can be easily stored and also safely.

It has a simple structure and is easy to implement.
