JPS585025Y2 - Mirror plate for door bag - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a head panel for a door case, and more particularly to a head panel provided with reinforcing recesses or protrusions with improved surface strength and excellent design.

□Generally, a shutter bag is equipped with a mirror plate to protect the stored shutter.

With the spread of metal fittings in recent years, this mirror plate is made of iron, copper,
Although it is constructed from a metal plate material such as aluminum, this part is subject to wind pressure and unexpected shock, so it is required to have strength such as wind resistance and impact resistance.

For this reason, head panels usually have U-shaped reinforcing grooves formed in the horizontal direction on their surfaces, or are constructed from a number of plate members similar to conventional wooden head panels, with an upper plate placed above the upper end of the lower plate member. The lower ends of the members are overlapped, and the lower end of the upper plate member is further overlapped on the upper end of this upper plate member, and the lower ends of the upper plate member are sequentially joined in the same manner and attached to the support frame to form one mirror plate. , the strength was improved by the polymerized portion.

In addition, with this configuration, the end plate body as a whole has a continuous pattern of horizontal stripes approximately equivalent to the width of the plate, so
It also matches the image of wooden mirror panels in traditional Japanese houses, and the material has become quite popular even when metal is replaced.

However, since these reinforcement parts of the head plate are provided only in the lateral direction, the bending strength of this part is high, but in reality, force is also applied to the head plate in the diagonal direction, and the bending strength in this direction is small.

For example, the central part of the mirror plate furthest from the support frame is the weakest part in terms of strength, but if force is applied to this part from the front, this force will be applied not only vertically and horizontally but also diagonally.

Therefore, when force is actually applied, the panel may become twisted due to the difference in surface strength of the panel, and the attachment to the frame may become loose, causing a rattling noise, or the storage storm door may not be adequately protected. I don't like it.

In addition, appearance has recently become an important element as a condition for a comfortable residence.

In this respect, there are usually windows, especially on the east or south side of the house.
Many glass shoji screens are installed, and each one is equipped with a shutter, so the shutters occupy a considerable part of the exterior of the house, and their design effect cannot be ignored. However, it was just the same continuous pattern of horizontal stripes as the old one, and lacked freshness.

The purpose of the present invention is to solve the above-mentioned drawbacks, particularly to propose a mirror plate for a door pocket that has improved surface strength and is also excellent in design effect.

That is, the present invention is attached to a rectangular frame body and has at least one reinforcing groove in the flat part between the reinforcing grooves of the end plate main body, which is provided with U-shaped reinforcing grooves at regular intervals. It is characterized by having a reinforcing recess or projection formed by continuously forming a substantially diamond-shaped recess or projection and at least one elongated recess or projection outside both ends of the recess or projection. shall be.

Embodiments of the present invention will be described below with reference to the drawings.

In addition, FIG. 1 is a front view of the end plate according to the present invention, FIG. 2 a,
1) is a perspective view showing the configuration of the end plate main body, FIGS. 3 and 4 are cross-sectional views taken along the line A-A and B-B in FIG. 1, and FIG. 5 is a perspective view showing the configuration of the end plate main body according to the present invention. FIG.

In the figure, reference numeral 1 indicates the end plate main body.

This mirror plate main body 1 is attached to a rectangular frame formed by a vertical frame 2 and an upper and lower frame 3.

Further, the end plate main body 1 can be constructed from a single plate-like material, or can be constructed by connecting a large number of single plates.

In other words, when constructing a single plate, as shown in Figure 2a, a vertically long metal plate made of iron, copper, aluminum, etc. is bent horizontally at regular intervals into a U-shape. All you have to do is form the reinforcing groove 4.

In addition, when configuring the end plate main body 1 by connecting veneers,
As shown in Figure 2, after folding the upper end of the narrow veneer 1' made of the metal plate material inward, 1. Further, it is folded back in the opposite direction to form a locking groove 10, and the lower end is also bent to provide a locking edge 6 at the same level as the locking groove 10, thereby locking one of the veneers 1' configured in this way. By fitting and locking the other adjacent locking edge 6 into the groove 10 as shown in FIG. 4, these veneers 1' are successively connected integrally to form the end plate main body 1.

When connected in this way, a reinforcing groove 4 is formed in the connecting part,
Furthermore, since the ends of the adjacent veneers 1' overlap each other in this connecting portion, the bending strength is increased, which is preferable.

In either case, in the present invention, as shown in FIG. 5, in addition to the above-mentioned horizontal reinforcing grooves 4, a diamond-shaped recess 5a is provided in the center of the plane part 1b between these reinforcing grooves 4, 4. ,
Further, elongated end recesses 5b are formed outward from both ends of the central recess 5a.

With this configuration, the entire mirror plate will have a continuous pattern of straight lines and rhombuses, as shown in FIG. , a mirror plate with a novel design not seen in conventional products can be obtained.

Moreover, the above-mentioned recessed portions are not only effective in terms of design, but also can improve the surface strength of the end plate main body 1.

That is, the central recessed portion 5a has a rhombic shape, and the opposite side equivalent portions p, p
Since ', q, and q' are parallel to each other, the recess 5a is composed of a reinforcing groove composed of the parallel opposite side portions p and p', and the other pair of opposite side equivalent portions q and q'. It can be considered that the reinforcing grooves 4 are integrated with each other, and the portions corresponding to the opposing sides are not parallel to the reinforcing grooves 4, respectively.

Therefore, it is possible to obtain bending strength in directions that cannot be obtained with the reinforcing grooves 4, and it is possible to ensure surface strength over the entire central portion.

Also, the end recesses have the same reinforcing effect as the reinforcing grooves 4, but this improves the surface strength of the end plate body against bending in the same lateral direction as the reinforcing grooves.

Note that if the end recesses 5b' are formed not only in the lateral direction but also in the oblique direction, the surface strength of the recesses 5b' in the oblique direction will be increased as well as in the central recess 5a. preferable.

Furthermore, the formation of the end recesses 5b and 5b' provides favorable results in terms of molding.

That is, when forming a diamond-shaped central recess on the flat part 1b of the end plate body, both ends are squeezed to form an acute angle, so during actual molding, radial drawing wrinkles are generated outward from the acute angle ends. Unfavorable in appearance.

Therefore, if the end recesses 5b are continuously formed in this portion, the occurrence of drawing wrinkles can be prevented and the finish of the recesses can be improved.

Incidentally, the side end portion of the end plate main body 1 is bent as shown in FIG. 2 a, l) to form a bent piece 1a.

When formed in this manner, the bending strength of the side end portions of the end plate main body 1 is improved, and together with the recesses 5 a and 5 b in the central portion, the strength of the flat portion of the end plate is further improved.

As shown in FIGS. 3 and 4, the end plate main body constructed as described above is usually constructed by inserting the end plate main body 1 into storage grooves 2a and 3a of a rectangular frame formed by a vertical frame 2 and an upper and lower frame 3. , just fix it with rivets 7 or the like.

As a result of the above-mentioned configuration of the present invention, the surface strength of the head panel can be greatly improved, and the present invention breaks away from the image of conventional head panels and provides a head panel with a novel design suitable for metal fittings. As a result, it can significantly contribute to improving the appearance of the building□.

In addition, although the example in which the recessed part was formed in the surface of the end plate main body 1 was shown above, the present invention is not limited to the recessed part, and it is also possible to form a raised part on the surface.

In addition, although the above example shows an example in which one diamond-shaped reinforcing recess is provided in the plane part between the reinforcing grooves of the end plate main body, the invention is not limited to the above, and two reinforcing recesses are provided in the present invention. More than one may be provided.
