【Example】

 FIG. 1 is a perspective view of a blind lid A according to an embodiment of the present invention as viewed from the back side. This blind lid A is a rectangular blind lid that has been improved in design by forming a slanted portion 11 (see FIGS. 3 to 5) on the surface side peripheral edge portion to make the outer edge thin by delustering with a textured finish. A plate 1, a support 2 projecting from the back surface of the blind plate 1, and first and second projecting pieces 3 and 4 formed at two positions of the beam portion 21 of each support 2 are provided. These are made of synthetic resin and are integrally formed.

The support body 2 is formed in a gate shape having a beam portion 21 and leg portions 22 and 22 on both sides thereof, and the leg portion 22 is provided between each leg portion 22 and 22 and the blind plate 1. , 22 are provided with reinforcing bracket portions 23, 23 for forming a right angle. A pair of such supporting bodies 2 are provided so as to project in the symmetrical state near the opposite side portions 12 and 13 of the blind plate 1. In the blind plate 1, the rectangular annular portion outside the portion surrounded by the pair of supports 2, 2 and the bracket portions 23, 23 attached to them is the mouth of the opening 100 described later. It is formed as an edge 14 which is applied to the edge surface. In other words, the shape and size of the portion formed by the pair of support bodies 2, 2 and the bracket portions 23, 23 attached to them are substantially the same as the shape and size of the opening 100 described later.

The protruding pieces 3 and 4 are formed from the beam portion 21 of the support 2 toward the blind plate 1. The outer surface of the first projecting piece 3 is located further outward from the support 2 as it is farther from the beam portion 21, that is, in a direction opposite to the opposing direction of the pair of support bodies 2, 2. An inclined flat guide surface 31 and a flat steep surface 32 following the guide surface 31 are formed. Further, a first engaging surface 33 located outside the support body 2 is formed at the tip of the first projecting piece 3. The second projecting piece 4 has a flat guide surface 41 inclined on the outer surface thereof so as to be positioned further outward than the support body 2 as the distance from the beam portion 21 increases, and a flat steep surface 42 following the guide surface 41. And are formed. Further, at the tip of the second projecting piece 4, two engaging surfaces 43 and 44, which are located outside the support body 2, are formed stepwise. The facing distance between each of the above-described engaging surfaces 33, 43, 44 and the edge portion 14 of the blind plate 1 is the narrowest facing distance between the first engaging surface 33 and the edge portion 14. The facing distance between the second engaging surface 43 and the edge portion 14 and the facing distance between the third engaging surface 44 and the edge portion 14 become wider in this order. Whether the third engagement surface 44 projects more outward than the second engagement surface 43 than the support 2, and the second engagement surface 43 projects further outward than the first engagement surface 33 in the support 2. , Or the same level as the first engaging surface 33.

Next, a rectangular small piece 5 having the same width as that of the blind plate 1 is integrally extended on one specific side portion 12 of the blind plate 1, and the boundary between the small piece 5 and the blind plate 1 is extended. A thin portion 51 is formed on the portion. Further, the surface of the small piece 5 is matt-finished by graining, and an inclined portion 52 is formed on the peripheral portion on the surface side to make the outer edge thin. The thin portion 51 is designed to be broken when bent. Such bending breakability of the thin portion 51 is satisfied by appropriately selecting the synthetic resin as the material of the blind lid A. For example, when AS resin is selected as the material, the thin portion 51 can be easily bent and broken. It is possible, and the fracture surface becomes a beautiful fracture surface without burr.

FIG. 2 is a front view of the state in which the blind lid A is attached to the opening 100 of the panel P as seen from the rear surface side of the panel P, and the left half of FIG. The right half of is the case where the length of the opening 100 is short. 3 is a sectional view taken along line III-III in FIG. 2, and fourth is a sectional view taken along line IV-IV in FIG.

As can be inferred from these figures, when the panel P having the same thickness as the facing distance between the edge portion 14 of the blind plate 1 and the third engaging surface 44 is targeted, the panel shown in FIG. As described above, the blind lid A is attached by gripping the lip edge portion 101 of the opening 100 by the edge portion 14 of the blind plate 1 and the third engaging surface 44, and the edge portion 14 of the blind plate 1 and When a panel P having a thickness approximately the same as the facing interval with the first engaging surface 33 is targeted, the edge 100 of the blind plate 1 and the first engaging surface 33 cause the opening 100 of the opening 100 as shown in FIG. The blind lid A is attached by gripping the lip 101. Further, when the panel P having the same thickness as the facing distance between the edge 14 of the blind plate 1 and the second engaging surface 43 is targeted, the blind plate is indicated by the phantom line A in FIG. The blind lid A is attached by gripping the rim 101 of the opening 100 with the first edge 14 and the second engagement surface 43.

In such a blind lid A, since the first projecting piece 3 and the second projecting piece 4 are both projected from the beam portion 21 of the gate-shaped support body 2, these projecting pieces 3, 4 are provided. When an inwardly directed force is applied to the beam portion 21, the beam portion 21 is twisted or bent by the force to displace the protruding pieces 3 and 4. Therefore, when the blind plate 1 is held by hand and the pair of supports 2 and 2 are pushed into the opening 100 when the blind lid A is attached to the opening 100, the respective supports 2 are inserted into the rim of the opening 100. When the guide surfaces 31 and 41 of the projecting pieces 3 and 4 come into contact with the rim and are pushed inward while moving, the beam portion 21 is twisted or bent, so that the projecting pieces 3 and 4 are moved to the beam portion 21. Gradually turn inward with the vicinity as a fulcrum. Then, when the support 2 is completely inserted and the edge portion 14 of the blind plate 1 hits the surface of the rim portion of the opening 100, the beam portion 21 approaches the original state with elasticity peculiar to synthetic resin. Return to. Therefore, as the beam portion 21 returns, any one of the first to third engagement surfaces 33, 43, and 44 engages with the back surface of the rim portion 101 of the opening 100.

The vertical length of the opening 100 when the first engagement surface 33 is used for mounting the blind lid A needs to be substantially the same as the mutual distance between the outer surfaces of the pair of supports 2 and 2. (See the right half of Figure 2). However, when the second engagement surface 43 and the third engagement surface 44 are used, the longitudinal length of the opening 100 is substantially the same as the mutual distance between the outer surfaces of the pair of support bodies 2 and 2, but is shorter than that. It may be long (see the left half of Figure 2). In this case, depending on the length of the opening 100, the first projecting piece 3 and the second projecting piece 4 remain pressed against the rim of the opening 100 after mounting, and the projecting pieces 3 and 4 of the supporting body 1 are retained. It is in a state of being displaced slightly inward with the vicinity of the beam portion 21 as a fulcrum.

When the supporting bodies 2 and 2 projecting from two positions on the back surface of the blind plate 1 as in this embodiment are provided with the first projecting piece 3 and the second projecting piece 4 symmetrically with respect to each other. , The first engaging surfaces 33, 33, the second engaging surfaces 43, 43, and the third engaging surfaces 44, 44 are arranged at the positions along the diagonal line of the blind plate 1, respectively, so that the mounting state in the opening 100 is It has the advantage of being stable. In addition, by extending the small piece 5 on the blind plate 1, there are the following advantages. That is, when the display H such as the name of the mounting part is attached to the side of the opening 100 as shown in FIG. 5, and the user wants to wake up by hiding the display H of the opening 100 blocked by the blind plate 1, the same figure is used. The small piece 5 can be left attached to the blind plate 1 like the blind lid A attached to the left side opening 100, and the small piece 5 can largely hide the display H. On the contrary, when the user wants to be able to see the display H of the opening 100 closed by the blind plate 1, the thin portion 51 is bent and broken, and the blind lid A attached to the opening 100 on the right side of FIG. You just need to remove the small piece 5. On the other hand, as shown on the right side of the figure, it is possible to close one opening 100 by arranging a plurality of (two in the figure) blind lids A and A in a long opening side by side. Furthermore, for long openings, blind lids may be used as spacers, and parts such as relay sockets may be attached to the openings on one or both sides.

In this embodiment, the blind plate 1 is provided with a pair of supporting bodies 2 having the first projecting piece 3 and the second projecting piece 4, but this point is that only one supporting body 2 is provided. You may stay. In this case, for example, the bracket portions 23, 23 of the support body 2 are extended to a length corresponding to the longitudinal length of the opening 100, and the leg portions 22, 22 of the support body 2 support one rim of the opening 100, and the bracket portion The other end of the opening 100 is supported at the ends of the holes 23, 23. Further, one support body 2 may be provided even for the blind lid A that is attached to the slit-shaped opening having the same thickness as the support body 2. Further, it is not always necessary to provide both the first projecting piece 3 and the second projecting piece 4, and either one may be provided. Further, the protruding piece may have only one engaging surface.

By the way, as a configuration for allowing the blind lid to be attached to the opening with one touch, generally, the configuration shown in FIG. 6 can be considered. That is, in this product, the arm 6 is provided on the back surface of the blind plate 1, and the engaging claw 61 is formed at the tip of the arm 6, and the engaging claw 61 and the blind plate 1 form the rim of the opening 100. The engaging claw 61 is inserted into the opening 100 by utilizing the bending of the arm 6 during the mounting operation. Therefore, in a blind lid that can be mounted in the opening 100 formed in the thin panel P or the like, the length of the arm 6 is shortened so that the distance between the engaging claw 61 and the blind plate 1 is reduced by the thickness of the metal plate. Need to be adjusted to. However, if the length of the arm 6 is shortened to the extent that the requirement is satisfied, the arm 6 will hardly bend. Therefore, the blind lid configured as shown in FIG. 6 cannot cope with the opening 100 formed in the thin panel P or the like. On the other hand, since the blind lid A of the present invention displaces the projecting pieces 3 and 4 by utilizing the twisting and bending of the beam portion 21 of the support 2 as described above, the thin lid panel P is However, it has been confirmed that it can be used even for control panel panels and metal cases of equipment and instruments with a thickness of about 0.8 mm. Further, in the blind lid A in which the small piece 5 is extended to the blind plate 1 through the thin-walled portion 51 having folding breakability as in the above-described embodiment, the thin-walled portion 51 has a bending breakability. Even if the support 2 is made of an excellent synthetic resin, the displacement of the projecting pieces 3 and 4 is absorbed by the twisting and bending of the beam portion 21, so that the projecting pieces 3 and 4 may break. Don't worry.

[0019]

[Effect of the device]

 According to the present invention, the blind lid can be securely attached to the opening simply by performing a one-touch operation of holding the blind plate by hand and pushing the support into the opening such as the panel. In particular, when the support is pushed into the opening edge, the projecting piece passes through the opening edge due to the twisting and flexing of the beam, so the engaging surface of the projecting piece also works on the opening of a thin panel or case. This can be dealt with by narrowing the gap between the blind plate and the back surface of the blind plate to match the thin plate.

According to the present invention, the surface of the blind plate is subjected to a matting treatment such as graining, or the peripheral edge of the blind plate is inclined to enhance the design, so that the appearance after mounting is beautiful. It is possible to finish. In addition, the product value can be improved by improving the designability in this way, and it is not necessary to use an expensive resin such as an acrylic resin.
