Description

[Detailed Description of the Invention] The present invention relates to a shutter attached to a cabinet, locker, etc.

For example, it is well known that shutters are used on the doors of cabinets that can store office documents, books, Western alcoholic beverages, clothing, etc., for example, because of the advantage of being able to easily obtain large openings. However, conventionally, the veneers constituting the shutter are connected by inserting the side ends of the adjacent veneers into each other, or by using hinges. In the former case, there is the problem that it is not easy to process the side edges of each veneer, and the associated problem is that the manufacturing cost is high. As the number of points increases, the manufacturing process becomes complicated, the manufacturing cost increases, and it also becomes heavy in terms of weight, making it difficult to open and close smoothly.Moreover, in order to change the shape of the shutter, there is a gap between adjacent veneers. Although it is necessary to have a gap between the cabinets, there is a problem in that dust enters the cabinet through the gap and the appearance of the cabinet is also deteriorated due to the gap.

This invention solves the above problems, and only requires simple processing on the side edges of each veneer, and the number of parts is small, making it possible to manufacture at low cost. It is lightweight, can be opened and closed smoothly, and can be installed on cabinets, etc., which eliminates gaps between adjacent veneers, prevents dust from entering the interior of the cabinet, etc., and maintains a good external appearance of the cabinet, etc. The purpose is to provide a shutter, and in order to achieve this purpose, a plurality of veneers having bent portions on both sides in the width direction with bent portions on the back side are used for connecting purposes, which are inserted through the bent portions. Connected by a steel wire, each end of the connecting steel wire is locked to each end side veneer, and the new curved part of the adjacent veneer is brought into contact with one end side of the connecting steel wire. In a shutter to be attached to a cabinet etc. equipped with a spring, only a semicircular part protruding outward in the width direction of the veneer is formed in the bending direction of the bending part, and the center part of the semicircular part in the bending direction Insert the connecting steel wire into the
A folded part is folded back on the back side of the end-side veneer and a part is included in the outer bent part of the veneer, and the spring is a coil spring, and the coil spring is connected to the folded part and the end-side veneer. This is characterized by a connecting steel wire wrapped around the inner bent portion of the plate.

Hereinafter, an embodiment of the present invention will be described based on the drawings. 1 is a single plate made of a long and thin steel wire, and both ends of the plate in the width direction are bent in a curved shape toward the back side to form bent parts 2, 2. In the bending direction of the bending parts 2, 2 of the veneer 1, only semicircular parts 2a, 2a protruding outward in the width direction of the veneer 1 are formed, and the semicircular part 2a
, connecting holes 14 are opened at several locations in the vertical direction (three locations in the figure) in the center of the bending direction of 2a, and the plurality of veneers 1 are arranged in parallel with the semicircular portions 2a, with the center portions of 2a abutting each other. The veneers 1 are connected by inserting the connecting steel wire 3 into the connecting hole 14.

One end of the connecting steel wire 3 is folded back and locked inside the veneer-side bent part 2 of the end veneer 1, and the other end is attached to the start end veneer 1.
It is not inserted into the outer bent part 2 of the starting end veneer 1, but is folded back to form a folded part 4, and the folded part 4 is partially included in the outer folded part 2 of the starting end veneer 1, and the connecting steel A coil spring 5 is elastically wound and interposed between the folded portion 4 of the wire 3 and the veneer-side bent portion 2 of the starting end veneer 1, and the bent portion 2 is locked by the elastic force of the coil spring 5. .2 Comrades are always in close contact.

6 is a movable wheel made of plastic material, etc., and the starting end is a single plate 1.
, is provided on the lower end back surface of the terminal veneer 1 and an appropriate number of veneers 1 between them, but it may of course be provided on the upper end back surface of these veneers 1 as well.

The shutter A according to the embodiment of the present invention is constructed as described above.

The above-mentioned shutter A can be installed in a cabinet, etc. in a double-opening format or a single-opening format, but the cabinet in the figure shows the shutter A of the present invention installed in a single-opening format, and this cabinet is the cabinet itself. 7
, a base plate 8, a top plate 9, and a shutter A.

The main body 7 has openings on the front and upper and lower surfaces, and the front opening surface of the main body 7 is the opening surface P of the cabinet.
A top plate 9 is attached with wood screws, bolts, etc. to the upper opening edge 10 that projects inward in a flange shape on the upper surface, and closes the upper opening surface and closes the upper opening edge 10.
A communicating sliding upper guide rail 11 with inner and outer side walls 18 and 19 is formed on the front side and the right side of the inner surface.

In addition, a base plate 8 is fitted onto a lower opening edge 12 that projects inwardly in the shape of a flange on the lower surface of the main body 7, and closes the lower opening surface. Rim 12
A communicating sliding guide rail 13 with inner and outer side walls 15 and 17 is provided on the front side and right side of the inner surface, but the main plate 8 has a notch shape at the front right corner, and the western end excluding that part is cut out. It is bent downward to form a side end portion, and the front side and right side end portions of the base plate 8 constitute the inner side wall 15 of the lower guide rail 13.

Note that the bottom surface of the front right corner of the main plate 8 has a vertical pivot shaft, and a guide roller 16 made of a non-metallic material such as plastic material, rubber material, wood, etc. is freely moved so as to come into contact with the back surface of the flat end of the shutter A. It is equipped in a rotatable manner.

The upper and lower ends of the shutter A above are the upper and lower guide rails 11
. The upper end of the shutter A is fitted into the upper guide rail 11, and the shutter A, which has been tilted, is moved upright until the inner side wall 15 comes into contact with the outer side wall 17 of the unformed lower guide rail 13. Next, move the shutter A inside the upper guide rail 11 to open the opening surface P of the cabinet, insert the main plate 8 into the cabinet body 7 through this opening surface P, and place the main plate 8 on the lower side of the main body 7. When placed on the opening edge 12 in a fitted manner, the inner side wall 15 of the lower guide rail 13 is constituted by the side end portion of the base plate 8.
The lower end of the shutter A is fitted into the lower guide rail 13.

In addition, the inner and outer side walls 18 and 19 of the upper guide rail 11
On the inner surface of the outer side wall 17 of the lower guide rail 13, longitudinally continuous protrusions 20 are attached so as to come into contact with the shutter A. By reducing the contact area and reducing the frictional force between the two, the shutter A can be moved smoothly within the upper and lower guide rails 11 and 13.

The embodiment is constructed as described above, and the opening and closing of the opening surface P of the cabinet of the shutter A is performed by the upper and lower guide rails 11,
This is done by moving a guide path constituted by 13 and guide rollers 16.

At this time, the shutter A must change its shape continuously from a flat plate shape to a curved shape and then a flat plate shape at the right corner of the front side of the cabinet body 7. The bending parts 2 of 1 and the semicircular parts 2a of 2, 2a move their abutting surfaces toward the back side, and the connecting part 2a of the bending part 2 is inserted into the center of the semicircular part 2a of the bending part 2. The steel wire 3 is attached to the semicircular portion 2 of the adjacent bent portions 2, 2.
The shutter A smoothly changes its shape from a flat plate shape to a curved shape while compensating for the shortage of steel wire between the central portions a and 2a by the compression of the coil spring 5 due to the tensile force.

Next, along the guide path, the semicircular parts 2a, 2a of the bent parts 2, 2 of the adjacent veneers 1 move their folding surfaces to the center, and the connecting steel wire 3 The surplus steel wire between the semicircular parts 2a, 2a of the adjacent new curved parts 2, 2 as they approach each other is replaced by the semicircular part between the bent parts 2, 2 of the adjacent veneer 1. 2a, 2a or absorbed by the expansion of the coil spring 5 to become a straight line, and the shutter A smoothly changes its shape from a curved shape to a flat plate shape.

At this time, the guide roller 16 provided at this corner rotates freely due to its contact with the moving shutter A, thereby causing the side walls 18 and 19 of the upper guide rail 11 at the corner to move freely.
and the outer side wall 17 of the lower guide rail 13 and the shutter A
This has the advantage that the shutter A can be smoothly moved to open and close the opening surface P of the cabinet by reducing the frictional force between the upper and lower guide rails 11 and 13 at the corner. There is no unpleasant metallic friction noise between the shutter A and the shutter A.

Note that since the roller 16 is made of a non-metallic material, it is natural that no unpleasant metallic friction noise is generated between the roller 16 and the shutter A.

In this way, the shutter A can continuously and smoothly change its shape from a flat plate to a curved shape and then to a flat plate, and the shutter A is made up of a plurality of veneers 1, Only an appropriate number of connecting steel wires 3, the same number of coil springs 5 as the connecting steel wires 3, and an appropriate number of movable wheels 6 are used, the number of parts is small, and it is relatively lightweight. By adding the function and the effect of the protrusion 20, the shutter A moves smoothly to open and close the opening surface P of the cabinet, and the above-mentioned shortage of steel wire is compensated by the compression of the coil spring 5. Adjacent veneer 1
The surplus steel wire is absorbed by moving it to the semicircular part 2a, 2a between the bent parts 2, 2 of the veneer 1, or by elongating the coil spring 5. The semicircular parts 2a, 2a of the veneers 1, 2a can always be brought into close contact with each other, and there is no gap between the veneers 1, 1, preventing dust from entering the cabinet, and improving the external appearance of the cabinet. are also well maintained.

In addition, since the shutter A changes its shape, the member connecting the veneers 1 is required to have a large elastic modulus, tensile strength, and fatigue limit, but in the present invention,
Since the above three types use large steel wires, they can accommodate changes in the shape of the shutter A.

Of course, among steel wires, it is more preferable to use piano wire, etc., which has particularly excellent mechanical properties in the above three types.

In addition, in the embodiment, the coil spring 5 is connected to the connecting steel wire 3.
Although the coil spring 5 is attached to the starting end of the single plate side, the coil spring 5 may be attached to the terminal end of the connecting steel wire 3 on the single plate side, or to both ends of the connecting steel wire 3.

As described above, the present invention is capable of smooth shape changes and is relatively lightweight, so the shutter can smoothly open and close the opening of the cabinet, has a small number of parts, and is made of single plate Since only simple processing is required on the side edges, it can be manufactured at low cost.Moreover, there is always no gap between the veneers, preventing dust from entering the interior of the cabinet, etc., and improving the appearance of the cabinet, etc. The appearance is maintained well, and in addition, since steel wire is used for the connecting member between the veneers, it can accommodate changes in the shape of the shutter.

In particular, in the present invention, only a semicircular part protruding outward in the width direction of the veneer is formed at the bending part on both sides of the veneer in the width direction, and the semicircular part is connected to the center part in the bending direction. Since the steel wire is inserted through the shutter, whether the shutter is deformed into a curved protrusion shape on the front side or curved protrusion shape on the back side, if the degree of deformation is the same, the adjacent veneer The bent portions are in the same contact state through the semicircular portions, and the shortfall between the veneers on both ends of the connecting steel wire due to the mutual separation of the center portions of the adjacent semicircular portions in the bending direction is also the same. Therefore,
The shutter can be smoothly deformed into a curved protrusion shape without directionality on either the front side or the back side, and there is no fear that the bent portion will be deformed in this case.

In addition, the spring that brings the bent portions of adjacent veneers into contact is a coil spring, and the coil spring is wound around the connecting steel wire between one end of the connecting steel wire and the inner bent portion of the end-side veneer. Because the shutter is deformed, the shortfall between the single plates on both ends of the connecting steel wire can be compensated for by the compressive deformation of the coil spring. Alternatively, local deformation into a large curved protrusion shape can be easily and smoothly performed.

Furthermore, since the above-mentioned one end of the connecting steel wire is folded back on the back side of the end-side veneer and a part is wrapped inside the outer bent part of the veneer, the coil spring can be used for connecting. It can be easily attached to the steel wire, and the folded part fits well, so that the folded part does not protrude from the back side of the veneer, or
There is no risk that the folded portion will interfere with items stored in the cabinet or the like.

The present invention has the various advantages mentioned above and is an extremely practical invention.
