``Problems to be solved by the invention'' Most of the connector mounting members currently in use have reverse grooves or grooves shaped like the ones shown in Figures 7 and 8, or similar shapes. However, due to the structure of conventional connectors as illustrated in FIGS. 9 and 10, for example, the connector in FIG.
The connector shown in Figure 10 cannot be used on a sign board that has the connector attachment member shown in Figure 7 attached, so please install it in a manner that is compatible with it. It can only be used for parts and has the drawback of not being versatile.

The purpose of the present invention is to eliminate these drawbacks and provide a so-called versatile connector that can be used to connect sign boards to which different types of connector mounting members are attached. .

"Means for Solving the Problem" A connector main body of a predetermined length having clamping substrates substantially parallel to both ends, and clamping plates overlapping each of the clamping substrates are provided. The clamping substrate and the clamping plate are configured such that clamping force is imparted by screws provided at appropriate positions between both ends thereof, and the positions of the screws are provided on the opposing surfaces of each of the clamping substrates or the clamping substrates. At a position further away from each other in one end direction, the space between the sandwiching substrate and the sandwiching plate at that position is filled with a cover raised from the back side of the sign of a connector mounting member that also serves as a reinforcing member attached to the backsides of the signboards. This is because a spacer part is provided to keep the wall thickness the same as or greater than the thickness of the clamping part.

"Function" At the opposite side of the clamping board and clamping plate from the side where the spacer part is provided when viewed from the position of the screw, the connector mounting member attached to the back side of each sign board is covered. The sign boards are connected to each other by sandwiching the clamping part, tightening the screw, clamping the clamped part at the opposite side, and connecting the connecting plate mounting members to each other.

"Example" Figures 1 to 4 show a first embodiment of the connector according to the present invention, and Figures 1 and 2 show the connector according to the first embodiment, An example is shown in which the sign plates a to which the connector attachment members 1 illustrated in FIG. 7 are attached are interconnected.

4 is a sandwiched substrate 41, 4 in a state substantially parallel to both ends.
1, which is integrally molded from an aluminum alloy, and a hole 42 through which a screw 6 is inserted is provided between both ends of a sandwiching substrate 41. Reference numeral 5 denotes a clamping plate made of aluminum alloy that overlaps each of the clamping substrates 41, and includes holes 42 of the clamping substrates 41.
A screw hole 51 is formed at a position that coincides with the
The structure is such that a screw 6 is screwed into this screw hole 51 from the side of the sandwiching substrate 41 to apply a clamping force to the sandwiching substrate 41 and the sandwiching plate 5.

On the surface of the clamping plate 5 facing the clamping substrate 41, a clamping plate is provided at a position away from the position of the screw 6 in one end direction (towards the upper end in FIG. 1) and the clamping board 41 at the position. The space W between the plate 5 is replaced by a pinched part b floating from the back surface of the sign board a of the connector mounting member 1 which also serves as a reinforcing member attached to the back surface of the sign board a, that is, a reverse groove shape in the mounting member 1. A spacer portion 52 is integrally formed to maintain the wall thickness w or more of the upper plate end portion 11a of the portion 11.

When viewed from the position of the screw 6, the spacer portion 52
(In Figure 1, screw 6
Guide the sandwiched part b of the connector mounting member 1 between the sandwiched substrate 41 and the sandwiched plate 5 at the lower part of the sandwiched substrate 41 and the sandwiched substrate 5 by tightening the screw 6
The clamped portion b is clamped between the clamping plate 5 and the clamping plate 5. Such connectors are used at both ends of the connector attachment member 1 to connect the mutual sign plates a, a.

Spacer portion 52 between the sandwiching substrate 41 and the sandwiching plate 5
The space W at the position is the spacer portion 52
Because of the presence of the screws 6, the thickness w of the clamped portion b of the connector mounting member 1 is always maintained to be equal to or greater than that of the clamping substrate 41 and the clamping plate 5. The clamping force thus applied acts on the clamped portion b to the maximum extent and does not weaken over time.

FIGS. 3 and 4 show a state in which sign plates a are connected to each other using the connector of the first embodiment to which the connector attachment member 1 of the type illustrated in FIG. 8 is attached. The section is illustrated. In the case of this figure, the portion of the connector attachment member 1 attached to the back surface of the sign plate a that rises from the sign plate a, that is, the end of the inward flange 15 of the grooved portion 14 is the sandwiched portion b. By sandwiching this portion between the sandwiching substrate 41 and the sandwiching plate 5 as in the case of FIGS. 1 and 2, the two sign boards a are connected.

In the connector according to the present invention, the spacer 5
2 can be similarly implemented by providing it on the side of the sandwiching board 41 as illustrated in FIG. The same effect can be achieved by using a nut 61 in place of the screw hole 53, and furthermore, the same effect can be achieved by using the screw 6 and nut 61 in opposite directions in the figure. Further, as shown in FIG. 6, the clamping plate 5 can be used with the clamping board 41 stacked on top of the other. In this case, the clamping plate 5 is provided with screw holes 53. , sandwiching substrate 41
A screw hole 43 is provided in the. Furthermore, the connector main body 4
The angle between the clamping substrate 41 and the clamping substrate 41 does not need to be perpendicular to the plane as in the previous embodiment, and it is also possible to form the entire connector main body 4 including the clamping substrate 41 into a Z-shaped plane.

"Operation of the invention" The connector for connecting the sign boards in the double-sided sign according to the present invention has a connector main body of a predetermined length that has sandwiched substrates substantially parallel to each other at both ends, and a connector body that overlaps each of the sandwiched substrates. and a clamping plate, configured such that a clamping force is applied to each of the clamping substrates and the clamping plate by screws provided at appropriate positions between both ends of the clamping substrate, and each of the clamping substrates or the clamping plate On the opposite surfaces of the indicator plates, there is a connecting device which doubles as a reinforcing member attached to the back surfaces of the sign boards, and which is installed at a position away from the position of the screw in the direction of one end, and which extends the space between the sandwich board and the sandwich plate at that position. Since a spacer part is provided to maintain the thickness of the clamped part of the mounting member that rises from the back surface of the sign board to be the same as or greater than that, it can be applied to different types of connector mounting members, making it more versatile than conventional ones. It is possible to obtain something with a certain degree of stability, and it is also possible to make a strong connection.
