Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a device for interconnecting panels made of extruded aluminum, which constitute, for example, a truck lift.

BACKGROUND TECHNOLOGY Conventionally, this type of panel connecting device has been provided with engaging portions on both sides of the connecting portions of a pair of panels to be connected to each other, and forcibly fitting the engaging portions together. Therefore, it is known that both panels are connected to each other.
(Refer to Publication No. 116514). However, with such conventional devices, high precision is required for the fitting portions during panel manufacturing, and therefore, panel manufacturing is extremely troublesome. Further, the work of forcibly fitting the panels together was not easy and required a large amount of force. Another problem was that once the panels were fitted together, it was very difficult to disassemble them for replacement. Furthermore, conventionally, a pair of panels to be connected to each other are combined with each other, a gap is provided at the connecting portion of the panel, and the connecting member having a generally T-shaped cross section is forced into the gap. When the connecting edges of both panels are pressed by the engaging convex edges on both sides of the connecting member,
It is known that both panels are connected to each other (see Japanese Utility Model Publication No. 52-28245). However, in such conventional devices, when the coupling member is displaced due to vibration etc. while the panel is in use,
There was a risk that the panel connections would come loose. Furthermore, when connecting the panels, a very large amount of force is required because the connecting members are forcibly inserted, and furthermore, once the panels are connected, it is difficult to disassemble them for replacement.

In order to solve this problem, conventionally, male and female fitting parts are provided at the edges of the left and right side walls of each connecting end of a pair of upper and lower extruded panels to be connected to each other, and both panels are connected to each other. Both panels are interconnected by fitting the male and female fitting parts together on both the left and right sides of the connection end of the panel, and
A panel connection device has been proposed in which a hollow part is formed at the connecting part of both panels, and a core member (stator) made of extruded material is inserted into this hollow part over almost the entire length of the panel (actual). (Refer to Publication No. 54-55109). However, with this conventional device,
Grooves are provided on the end walls of both panels, and when these end walls are fitted together, a hollow space is formed. Therefore, when both panels are connected, the ends Since the walls were double-walled, more materials were required for the panels, which increased the cost of manufacturing the panels. In addition, the connecting end of each panel is provided with a male and female mating part, an end wall, and a groove in the center of the end wall, and since the cross-sectional shape of the connecting end of each panel is complicated, There was a problem in that it was extremely troublesome to produce a molding die, the cost of the die was high, and the manufacturing cost of the panel was further increased.

Purpose of the invention The purpose of this invention is to solve the above problems, to have a simple cross-sectional shape of the connecting ends of a pair of panels to be interconnected, and to make it possible to manufacture both panels easily and inexpensively. In addition, the cross-sectional shape of the core member inserted into the connecting portion of both panels is simple, and it is easy and inexpensive to manufacture. It is an object of the present invention to provide a panel connecting device which can firmly press and clamp the joining part and can connect both panels very firmly.
