Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a shutter-type storage cabinet provided in a kitchen facility or the like.

[Conventional technology]

Conventionally, various storage cabinets have been adopted for kitchen equipment such as system kitchens, and the layout is properly laid out to improve work efficiency. Storage cabinets are generally drawer type or door type,
Items are stored by taking advantage of each feature. In addition to these types, shutter-type storage cabinets in which the shutter can be moved up and down are also widely used.

FIG. 5 shows a typical example of this shutter type storage cabinet, which is provided with a shutter 51 in a box-shaped main body 50 having one open surface. The shutter 51 is movable along a guide 52 provided on the side plate of the main body 50 and can be stopped at an arbitrary height. To hold this stop,
A shutter reel 53 using a mainspring is provided on a side plate, and a leaf spring 54 wound around the shutter reel 53 is attached to the shutter 51.
Connected to.

The shutter reel 53 has a casing 55 as shown in FIG.
With a spring mechanism connected to the mainspring mechanism built in,
A hole 54a is formed at the end of the leaf spring 54. Then, a screw is connected to the hole 54a and is connected to the back surface of the shutter 51 so that the shutter 51 can be held at an arbitrary height by utilizing the biasing force of the mainspring mechanism.

[Problems to be solved by the device]

However, the leaf spring 54 is strongly pulled in the direction of being wound inside the casing 55 due to the mainspring function inside the casing 55. Therefore, in order to prevent the leaf spring 54 from entering the casing 55, a nail or the like is inserted into the hole 54a, and the end portion of the leaf spring 54 is brought out of the casing 55 by hanging it on the outer periphery of the casing 55. It is necessary to use as.

As described above, in the case where the leaf spring 54 is held with nails or the like, if the leaf spring 54 is accidentally disengaged from the hand or is improperly fixed when screwed to the shutter 51, the leaf spring 54 immediately becomes inside the casing 55. Get in. For this reason, it is necessary to remove the casing 55 and repeat the work.
There is a danger that 54 will bounce off and cut your hands.

Further, since the biasing force of the built-in mainspring mechanism cannot be changed, the tension for holding the shutter 51 is constant. Therefore, when the size and weight of the shutter 51 are different depending on the product, it is necessary to prepare a plurality of dedicated shutter reels 53 in which the biasing force of the mainspring mechanism is appropriate. Further, depending on the installation conditions, fine adjustment of the tension may be necessary, and the conventional structure cannot cope with this at all, so that the lifting and lowering operation of the shutter 51 often fails.

Therefore, an object of the present invention is to easily and safely attach a shutter reel and to set tension.

[Means for Solving the Problems]

In order to achieve the above object, the shutter type storage cabinet of the present invention is a shutter type storage cabinet having a shutter reel for holding a shutter by a mainspring mechanism, wherein the shutter reel is fixed to a side plate of the cabinet. A base, a reel rotatably provided on the base and having a mainspring mechanism, and a wire having a fixture wound around a peripheral surface of the reel and connected to the shutter at one end thereof. And a stopper extending from the base constitutes a wire winding prevention mechanism for holding one end of the wire at a position apart from the peripheral surface of the reel.

〔Example〕

Hereinafter, the features of the present invention will be specifically described with reference to the embodiments shown in the drawings.

FIG. 1 is an exploded perspective view of a shutter reel provided in a cabinet of the present invention, FIG. 2 is a longitudinal sectional view, and FIG. 3 is a side view. The cabinet is similar to that shown in FIG. 5, and the description thereof is omitted.

The shutter reel has a base 1 having a screw hole 1a fixed to a side plate of a cabinet as a base, and a fixed shaft 2 integrated with the base. A reel 3 is rotatably attached to the fixed shaft 2, and a casing 4 that covers the whole is connected to the fixed shaft 2 by screws 4a. The reel 3 has a small diameter on the base 1 side as shown in FIG.
To wind. Further, a chamber 6a for accommodating the leaf spring 6 as a mainspring is provided at the end of the reel 3, and the elastic force of the leaf spring 6 urges the reel 3 in the winding direction of the wire 5. That is, one end of the leaf spring 6 is connected to the fixed shaft 2 and the leaf spring 6 is wound around the fixed shaft 2 in a direction to rotate in the direction in which the wire 5 is released, and the other end is provided around the chamber 6a. A structure for engaging the holding plate 6b is provided. With this structure, when the wire 5 is pulled down, the reel 3
Rotates in the direction of arrow A in FIG. 1, and at the same time, the reel 3 receives a biasing force in the direction of arrow B due to the reaction force of the leaf spring 6.
Then, by setting the magnitude of this biasing force to correspond to the weight of the shutter, the shutter can be held at an arbitrary height.

Further, a guide 7 made of synthetic resin is provided between the base 1 and the reel 3. This guide 7 has a truncated cone shape, and the wire 5 does not scatter and the reel 3
It is designed so that it can be wound around the circumference of.

Further, the base 1 is provided with a stopper 8 so that the entire wire 5 is not wound around the reel 3. The stopper 8 is a plate in which a part of the base 1 is projected to the reel 3 side, and is provided with a guide cylinder 8a through which the wire 5 passes. A fixing tool 9 for connecting to the shutter and a ring 10 for connecting the fixing tool 9 to the wire 5 are provided at one end of the wire 5. A screw hole 9a is opened in the fixture 9 and is connected to the back surface of the shutter with a screw (not shown).

In the above structure, the base 1 is fixed to an appropriate position on the side plate of the cabinet, and the fixture 9 provided at the lower end of the wire 5 is used.
The shutter can be supported by the wire 5 by connecting to the lower end of the shutter. Then, as described above, if the biasing force of the leaf spring 6 is set to an appropriate value corresponding to the weight of the shutter, the shutter can be held at an arbitrary height.

Here, since the stopper 8 is provided, the wire 5 is not wound around the reel 3 up to the fixture 9. That is, since the ring 10 abuts the lower surface of the guide tube 8a,
The fixture 9 is restrained on the lower surface side of the stopper 8. Therefore, as in the conventional example, the reel 3 of the wire 5 is utilized by using a nail or the like.
It is not necessary to prevent winding on the side, and the fastener 9
Even if the user accidentally releases his / her hand from the fixture 9 during the work of connecting the two, the work can be redone easily because the work stops on the lower surface of the stopper 8.

Further, if the wire 5 is pulled downward and the wire 5 is paid out from the peripheral surface of the reel 3, it is displaced from the chamber 6a side,
The biasing force of the leaf spring 6 can be changed. That is, after the wire 5 wound around the reel 3 is unwound and pulled out, a portion apart from the peripheral surface of the reel 3 is pulled out to the chamber 6a side, and the wire 5 is passed over the chamber 6a.
Change the tension of.

The change and setting of the tension of the wire 5 will be described with reference to FIG. One end of the leaf spring 6 is connected to the fixed shaft 2 and is spirally wound while rotating around the fixed shaft 2 in the clockwise direction (Fig. 4 (a)).

Therefore, in the illustrated case, the reel 3 by the leaf spring 6 is used.
The direction of the urging force to is counterclockwise. On the other hand, wire 5
Is wound around the reel 3 in the clockwise direction, and when the reel is pulled downward, an urging force acts on the leaf spring 6, and the shutter can be supported by this urging force.

Here, when the reel 3 is rotated clockwise without pulling the wire 5 at all (FIG. 4 (b)), the leaf spring 6 comes to be wound around the fixed shaft 2 and its biasing force is large. Change to become. It should be noted that, in the drawing, for the sake of easy understanding of the description, the leaf spring 6 is shown as having a reduced diameter to increase the radial density to increase the biasing force. Since one end of 6 is connected, the entire diameter is not reduced. At this time, since the reel 3 rotates in the direction in which the wire 5 is released, the wire 5 is loosened with respect to the peripheral surface of the reel 3. When the looseness is once displaced from the chamber 6a and wound again on the peripheral surface of the reel 3 as described above, the looseness disappears, and the wire 5
If it is released, it is held by the action of the stopper 8 (FIG. 4 (c)), and as a result, the urging force of the leaf spring 6 increases.

Contrary to the above, when the operation of releasing the wire 5 wound around the reel 3 is performed, the biasing force of the leaf spring 6 becomes small.

Thus, by handling the wire 5 and the reel 3 separately, the tension of the wire 5 can be set. Therefore, a single shutter reel can sufficiently cope with product use in which the weight is variously changed due to the difference in the height of the shutter.

Needless to say, such a tension can be set by providing the stopper 8 so that the entire wire 5 is not wound around the reel 3, and the simplification of the work and the tension setting are effective. Will be achieved.

[Effect of device]

As described above, in the shutter type storage cabinet of the present invention, a wire is wound around the reel of the shutter reel and the lower end of the wire is connected to the shutter so that the lower end of the wire is not wound around the reel. A stopper is provided. Therefore, when connecting the wire to the shutter,
Even if the wire is accidentally released, the entire wire is not wound on the reel, and the work can be immediately redone. Further, the tension of the wire can be set by changing the reaction force of the leaf spring, and it can be suitably used for a cabinet in which the weight of the shutter changes variously.
