Description

[Detailed explanation of the invention] [Industrial application field] The switchboard is called a mosaic panel, and the whole is divided into a vertical and horizontal grid pattern to form a lattice frame A of a predetermined size. Attach the necessary instruments, illumination lamps, sockets, etc. to the hole at the location, and install a blind cover called a plastic or metal tile to each other hole.
There are things that make up two boards.

By the way, the lattice frame A with the desired shape and size is
It is constructed by combining an arbitrary number of lattice blocks a of a certain size, which are made of metal or plastic and have a certain size, for example, the number of channels is 10 to 15 in the vertical and horizontal directions.

The present invention relates to a device used when two or more of these lattice blocks a are connected.

[Prior art]

Conventionally, various methods have been adopted for connecting at least two lattice blocks a, a. Typical examples include the use of a special connector called a coronet, as shown in FIGS. 6 to 8, and the use of special screws, as shown in FIGS. 9 and 10.

In the former case, the partition walls 2', 2', 3',
3' with the retainer piece 6a of the hook piece 6, and insert the circular tubular receiver 7 from the rear of the hook piece 6.
After inserting the partition walls 2', 2', 3', 3' to which the two lattice blocks a, a join into the insertion grooves 7a, 7a formed in the slots 7a, 7a, respectively, screw the nut 8 onto the hook piece 6. It is something that makes it a whole.

In the latter case, that is, when special screws are used, annular cylindrical portions 9 are provided at each intersection of the partition walls constituting the channel, and cylindrical portions 9 are provided at the top, bottom, left and right side ends of the lattice block a. A cylindrical part 9' having a shape divided into two is formed, and a cylindrical part 9'' having a shape in which the above-mentioned cylindrical part 9 is divided into four parts is formed at each of the four corners, and the front and back sides of the peripheral parts of the adjacent lattice blocks a, a are formed. A pair of bolts 10 from both sides
and nut 11, then bolt 10 and nut 1.
The short cylindrical portions 10a, 11a of 1 are fitted into the cylindrical portions 9', 9'', respectively, to form an integral body.

As an alternative to these, in FIG.
2, using a connecting piece equipped with an elastic holding piece as shown by 13 in FIG. There is a structure in which two or more lattice blocks a, a are connected to each other (for example, see Japanese Utility Model Application No. 56-43217).

[Problem that the invention attempts to solve]

When using a connector called Coronet,
A part of the coupling tool protrudes from the ditch shown at 1' in Figure 6, making the ditch that much narrower, making it impossible to attach instruments, illumination lamps, sockets, etc. to this ditch. This will cause inconvenience.

In addition, the method using special screws is an ideal connection method in terms of connection strength, but it is difficult to insert bolts.
The drawback was that it was extremely time consuming to tighten the screws.

On the other hand, as shown in FIGS. 11 and 12, a method in which connecting pieces equipped with elastic holding pieces are attached so as to intersect with each other in a plane from both the front and back sides of the lattice blocks a, The panels are arranged on a board, and a connecting piece is first attached to one side to form a panel of an appropriate size.Then, the panel is then turned over and a connecting piece is attached to that side, which improves work efficiency during assembly. It has a very bad drawback. In particular, when assembling panels, it is normal to
The size of the piece is approximately 1.5 m long and 1.5 m wide, but it is extremely troublesome to turn over such a large and somewhat heavy object. Since they are not attached, they are easily bent, and if they are bent, the lattice blocks that are being connected may separate again, or the connecting pieces may break. Therefore, jigs and devices for flipping are used at assembly sites, and these have become necessary. In addition, if the holding piece is formed with an engaging step that protrudes from the joint surface with the lattice block a, the shape of the engaging step should be adjusted when manufacturing this connecting piece. For this reason, a slide mold must be used, which has the disadvantage that the mold cost is correspondingly high, which increases the cost of the connecting piece.

The present invention is intended to eliminate all such drawbacks.

[Means for solving problems]

To achieve this objective, the present invention provides elasticity that can be bonded to the opposing inclined surfaces a', a' of the corners of at least two adjacent lattice blocks a, a, respectively, to hold these portions together. The holding claws 5, 5 are provided facing each other, and near the tip of each holding claw 5, 5, there is a lattice located on the side in a direction that does not protrude with respect to the joining surface with the inclined surface a'. Block a,
Engagement steps 5a, 5 that can engage with the back side of the partition wall of
form a.

[Effect]

Pin B having two opposing holding claws 5, 5
When inserted into the corners of at least two adjacent lattice blocks a, a from the front surface thereof, the flat surfaces of both elastic holding pieces 5, 5 will touch the opposing slopes of the two adjacent lattice blocks a, a. In addition to holding the abutting portions of adjacent lattice blocks joined to surfaces a and a, respectively, and as shown in FIGS. The joint portions 5a, 5a engage with the back sides of the partition walls of at least two adjacent lattice blocks a, a, respectively. Therefore, at least two adjacent lattice blocks a, a can be firmly connected so that they do not move even when subjected to forces in any of the vertical and horizontal directions.

〔Example〕

Embodiments of the present invention will be described based on the accompanying drawings.

In the embodiment, a case is illustrated in which four elastic holding claws 5 are provided facing each other. That is, as shown in FIGS. 1 and 2, holding claws 5 are made to protrude rearward from the four corners of the approximately octagonal contact piece 4, respectively. Further, near the tip of each holding claw 5, an engaging stepped portion 5a is formed as shown in FIG. When the pin B is inserted from the front into the intersection of four adjacent lattice blocks a as shown in FIG. It is located on the side, which is a direction in which it does not protrude from the grid, and is oriented so as to engage with the back side of the partition wall of the lattice block a.

As shown in FIG.
When inserted from the front into the intersection of the two lattice blocks a, the four holding claws 5 are tightly joined to the inclined surfaces a' at the corners of each lattice block a, thereby holding the four lattice blocks a together. At the same time, the engaging step portions 5a formed near the tips of each holding claw 5 engage with the back sides of the partition walls of the four lattice blocks a, respectively,
(FIGS. 4 and 5) Once the four adjacent lattice blocks a are connected, they can be firmly connected so that they do not move in any of the vertical and horizontal directions.

When connecting two adjacent lattice blocks a, it is only necessary to provide two holding claws 5. In short, the number of holding claws 5 may be provided in accordance with the number of lattice blocks a to be connected.

Further, the shape of the contact piece 4 is preferably made to match the shape of the intersection of the lattice blocks a to be connected. In this way, the contact piece 4 will fit snugly into the lower point a'' (Figs. 3 and 5) of the intersection of the lattice blocks a to be connected, and the pin B will not move accidentally after installation. There are no issues at all, and it also looks good.

By the way, this pin B is connected to the contact piece 4 as mentioned above.
A pair of holding claws 5, 5 are formed facing each other toward the rear, and the engagement step portion 5a of each holding claw 5, 5 is formed in a direction in which the engaging step portion 5a of each holding claw 5, 5 does not protrude from the joining surface with a' on the inclined surface. Therefore, when manufacturing this pin B, even if the spacing near the base of the opposing holding claws 5 and 5 is made to the same degree of accuracy as the spacing near the tip, it is difficult to use or otherwise There is no problem in that respect. Therefore, the mold for manufacturing this pin B does not need to be a slide mold, and the cost of the mold can be reduced accordingly, and the cost of the pin can be reduced accordingly.

A lattice block a having a constant size is partitioned into a checkerboard pattern by vertical and horizontal partition walls 2 and 3, and a large number of channels 1 and 1 are formed. Then, a plurality of these lattice blocks a are combined as shown in FIG. 5, connect four adjacent lattice blocks a to each other, and form 1 as shown in FIG.
Assume that there are two large grid frames A.

In addition, the vertical and horizontal partition walls 2 and 3 of lattice block a
are all the same thickness, but Fig. 2, Fig. 3,
As shown in FIG. 6, FIG. 7, and FIG.
3' is 1/2 the thickness of the other partition walls 2 and 3, and when combined, the partition walls 2' and 3' of the adjacent lattice block have the same thickness as the other partition walls 2 and 3. It's like this.

[Effect of idea]

According to the present invention, the pin B is connected to at least two adjacent pins.
Simply attach it from the front by connecting it to the opposing inclined surfaces of the corners of the two lattice blocks a, a, and each holding claw can be attached to at least two adjacent lattice blocks a,
The abutting portions of the adjacent lattice blocks a, a are held together by joining to the opposing inclined surfaces of the corners of the lattice blocks a, and the engaging step portions formed on each holding claw are attached to the adjacent lattice blocks a, Since each engages with the back side of the partition wall 2 of
The two lattice blocks a, a can be firmly connected so that they do not move even when subjected to forces in any of the vertical and horizontal directions.

Furthermore, in the pin used in the present invention, it is only necessary to finish the spacing near the base and the spacing near the tip to the same degree of accuracy due to the shape of the opposing holding claws and their engaging stepped portions. The mold for manufacturing does not need to be a slide mold, which reduces the mold cost and reduces the cost of the pin accordingly.
