Description

[Detailed description of the invention] A. Field of industrial application This invention is an improvement of a cabinet in which a number of unit rods are rotatably connected, and a side-opening shutter with an opening/closing handle provided at one end is set as the front opening. The present invention relates to a cabinet with a shutter that can restrict inward displacement of the shutter at the front opening side end and exhibit high safety against theft.

B. Conventional technology Conventionally, in a cabinet with a shutter, the shutter installed in the front opening of the cabinet has a number of unit component rods connected to each other so as to be rotatable inward of the cabinet, and a slide handle for opening and closing is provided at one end. The opening/closing guidance is performed by linear guide grooves provided on the upper and lower surfaces of the front opening of the cabinet, and an arcuate guide groove continuous with the linear guide grooves and connected to the shutter storage space provided on one side of the interior space of the cabinet. The arcuate guide groove is formed to be wider than the outline width of the polygonal shape so that the shutter, which has a large number of unitary rods connected to each other, can be bent into a polygonal shape at that portion and easily slide through. . Therefore, the gap between the arcuate guide groove and the component rod is larger than that in the straight guide groove portion, that is, the play in the radius of curvature direction of the guide groove of the component rod is larger in the arcuate guide groove portion, and In the arcuate guide groove, outward bending of the constituent rod connecting portion, which could not occur in the straight guide groove portion, occurred, causing problems such as rattling of the shutter. In addition, in recent years, most of the structural rods are made of synthetic resin because of their ease of molding, and they are easily bent by external forces in the direction of the thickness of the structural rods, especially for tall cabinets.
That is, in the case of a long structural rod, its curvature is noticeable, and this, together with the rattling in the arcuate guide groove, poses a crime prevention problem.

C. Problems that the invention aims to solve In view of the above-mentioned situation, the invention aims to solve the problem of a shutter at the end of the front opening of the cabinet, especially a shutter made of easily moldable synthetic resin unit rods. To provide a cabinet with a shutter that regulates inward displacement due to external force, suppresses lateral vibration when opening and closing the shutter, and exhibits high safety against theft when the shutter is closed.

D. Means for Solving the Problems In order to solve the above-mentioned problems, the present invention aims to separate the shutter storage space provided on the side of the internal space of the cabinet from the article storage space by using a side end of the front opening of the cabinet. At the front edge of the partition plate standing upright on the side of the internal space of the cabinet, the terminal end of the linear guide groove of the shutter provided on the upper and lower surfaces of the front opening of the cabinet, or the inside of the starting end of the arcuate guide groove that guides the shutter into the shutter storage space. A support member having a strength capable of restricting inward displacement of the shutter is attached close to the shutter over substantially the entire vertical length of the shutter to constitute a cabinet with a shutter.

E. Embodiment Next, details of the embodiment will be further described based on the illustrations shown in the attached drawings.

Figure 1 shows a typical embodiment of the present invention;
The figure shows a cross section thereof, and 1 is a cabinet, 2 is a shutter, 3 is a guide groove, 4 is a partition plate, and 5 is a support member. The cabinet 1 is formed by setting the shutter 2 in its front opening, partitioning a storage space 6 for the shutter 2 on one side of the interior space with a partition plate 4, which will be described later, and having a guide groove for guiding the shutter. 3 are provided with opposing openings in the top plate and bottom plate. In this embodiment, the structure of the cabinet 1 is a side-opening type with a shutter storage section provided at one end, but the structure is not limited to this, and a double-opening type or other types are also possible. The shutter 2 has a plurality of constituent rods 7 connected to each other so as to be rotatable inward, a pull handle 8 for opening and closing is provided at one end thereof, and a slider 9 having a substantially L-shaped cross section is provided at the bottom of the pull lever 8 and the constituent levers 7. has been established. Here, the constituent rod 7 has a male type connecting part 10 and a female type connecting part 11 on both sides of the connection, as shown in FIG.
In this embodiment, the male type connecting part 10 is formed into a cylindrical shape, and the female type connecting part 11 is fitted around the male type connecting part 10 so as to be rotatable. The handle 8 has a cylindrical shape with a part cut out and is made of synthetic resin that is easy to mold. However, other shapes and materials may also be used. The slider 9 is made of synthetic resin and has a handle at the center of its outer surface, and is provided at least at the lower end to allow smooth sliding inside the guide groove 3. It serves as a mounting part for attaching to the constituent rods 7, and the other part serves as a sliding part with a guide groove 3, which will be described later, and its tip is formed into a round shape so as to form a line contact. Further, the slider 9 is connected to the constituent rod 7.
It may be attached to all of... or it may be attached at intervals. The guide groove 3 consists of a linear guide groove 12 formed on the upper and lower surfaces of the front opening of the cabinet 1 and an arcuate guide groove 13 communicating with the shutter storage space 6.
Its shape has a recess with a substantially U-shaped cross section, the width of the linear guide groove 12 is set slightly larger than the width of the constituent rods 7... and the handle 8, and the width of the arcuate guide groove 13 is set to be slightly larger than the width of the constituent rods 7. Shutter 2 that connects many...
It is bent into a polygonal shape and is made wider than the outline width of the polygonal shape so that it can be easily slid through. Of course, guide grooves 3 are also provided on the upper and lower surfaces of the shutter storage space 6. The partition plate 4 is
This is provided to separate the article storage space inside the cabinet 1 from the shutter storage space 6, and is erected at one end of the interior space of the cabinet 1.Although not shown in the drawing, it can be used to attach a shelf board. It is also possible to provide an appropriate section. The support member 5 has a surface that is close to the inside of the arcuate guide groove 13 from the terminal end of the linear guide groove 12 or the start end of the arcuate guide groove 13 and follows the curve of the arcuate guide groove 13. Then bend the edge inward and attach the shutter 2.
To prevent the constituent rods 7 from getting caught when lateral displacement occurs during opening and closing of the shutter 2, and to provide cross-sectional strength capable of regulating inward displacement of the shutter 2 over substantially the entire vertical length of the shutter 2. The partition plate 4 is configured so as to be attached to the partition plate 4. Further, the support member may be attached to the partition plate 4 by screwing or welding, or it may be formed continuously and integrally with the partition plate 4, and its shape is such that it prevents inward displacement of the shutter 2. Any other shape may be used as long as it has a strength that can be controlled, for example, a shape such as a or b in FIG. 3 may be used.

With the shutter 2 closed, an inward external force is applied to the structural rods 7 located in the arcuate guide groove 13 on the side of the front opening of the cabinet 1, causing the structural rods 7 to move inward. Even if it curves to
Since the inward displacement thereof is regulated by the support member 5, the constituent rods 7 do not come off from the arcuate guide grooves 13 even if a strong inward external force is applied.

Further, when the shutter 2 is normally opened and closed, the support member 5 is arranged so as not to come into contact with the inner surface of the shutter 2, and does not interfere with the opening and closing of the shutter 2, but when the shutter 2 is opened and closed quickly. However, the width of the arc-shaped guide groove 13 is set wide so that the constituent rods 7 of the shutter 2 can be smoothly bent and passed, and the edge of the support member 5 is Since it is configured so that it does not get caught on the constituent rods 7, it does not interfere with the opening and closing of the shutter 2.

F. Effects of the invention According to the cabinet with shutter of the invention,
Despite the above-mentioned simple structure, even if an external force is applied from the front direction of the shutter 2 to the arcuate guide groove on the side of the opening of the front surface of the cabinet, the arcuate guide groove does not close to the inside of the starting end of the arcuate guide groove. Since a support member is provided that has the strength to restrict inward displacement of the shutter over almost the entire length of the shutter,
Further inward curvature of the shutter does not occur, and once the shutter is removed from the arcuate guide groove, it will not be damaged, which is very effective for crime prevention.

Furthermore, the present invention does not require any extra space for its configuration, and can be carried out using space that was previously unused, and can be easily assembled and manufactured by simply attaching it to the partition plate. be.
