Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel connecting device for a floor, wall (orientation) or the like which constitutes a loading platform of a vehicle.

[0002]

2. Description of the Related Art Conventionally, it has already been known that, for example, a cargo bed wall of a vehicle such as a truck, a panel made of extruded hollow aluminum material is connected to each other by fitting a required number of projections and depressions (for example, the actual exploitation model 51-). No. 14420 and Japanese Utility Model Laid-Open No. 56-8585), these hollow panels were connected by connecting bolts and nuts.

However, in such a conventional panel connecting device, it is necessary to form a bolt insertion hole in each hollow panel, and it takes a lot of man-hours to tighten the bolts of the hollow panels, so that the connecting work of the hollow panels is very difficult. Besides being troublesome, there is a problem that the weight of the luggage carrier wall itself cannot be increased due to the use of a required number of bolts and nuts.

In order to solve the above problems, therefore, the hollow panels are connected to each other by using connecting pins without using bolts or the like (Actual No. Sho 56-12268).
No. 8, No. 56-135370, etc.), or one in which a connecting member for connecting the two is fitted to the panel end portion where the concave and convex portions are fitted (No. 57-32063, No. 58).
No. 23745, etc.) has also been proposed.

[0005]

However, although the above-mentioned conventional one shows a great improvement in the weight of the panel as compared with the case of the bolt and the nut, in the work of connecting the panels to each other, for example, , Jitsukai Sho 56-12268
In the case of No. 8, it is necessary to join the vertically adjacent hollow panels by rotating one of the hollow panels with respect to the edge of the other hollow panel by a certain amount and then using the connecting pin. However, there is still a problem that workability is poor. Also, for example, in the case of Japanese Utility Model No. 57-32063,
Although it is relatively easy to fit the panels to each other, the work of fitting the connecting members is troublesome.

It is an object of the present invention to directly and surely connect a required number of adjacent hollow panels to each other directly and reliably by a simple operation without using bolts and nuts or connecting members having a specific shape. An object of the present invention is to provide a panel connecting device for a floor or the like.

[0007]

DISCLOSURE OF THE INVENTION According to the present invention, in a cargo bed floor of a vehicle in which a required number of hollow panels are joined to the left and right, the left panel of the adjacent hollow panels projects from the right side surface. The upper wall is provided with a groove at the right end, and the lower surface of the right end is provided with a retaining wall that extends substantially vertically downward and is elastically deformable to the left, facing the lower end of the retaining wall to the left. The right edge of the lower wall of the panel has a standing edge, and the left edge of the upper wall of the right panel has a hanging edge that fits in the groove of the left panel. The left end of the wall is provided with a standing wall formed on the right side part of the left end and a horizontal wall extending from the upper end of the standing wall to the left side and a hanging part having a hanging wall formed on the horizontal wall tip, The hanging edge of the right panel fits into the groove of the left panel, and the rising edge of the left panel The right side of the base is in contact with the left end of the lower wall, the tip of the rising edge is hooked on the right side of the hanging wall of the locking part, and the lower end of the retaining wall of the horizontal wall is in contact. There is something.

[0008]

According to the present invention, regarding the left and right adjacent hollow panels, the hanging edge of the left end of the upper wall of the right panel faces the groove of the upper end of the left panel of the left panel, At the standing edge on the right end, the locking part on the left end of the lower wall of the right panel,
Push the retaining wall to the left to make them face each other, and in this state, just push down the right panel to fit the hanging edge of the right panel into the groove of the left panel, while the rising edge of the left panel is The retaining wall that was hung on the hanging wall of the locking part of the right panel and pushed back to the left returned to its original state due to its elasticity, and the lower end of the retaining wall hits the upper surface of the horizontal wall of the locking part. As a result of being touched, the left and right panels are joined.

Further, in the above-mentioned panel connection, the lower end side of the retaining wall of the left panel is elastically deformed when the engaging portion of the right panel is arranged above the rising edge of the left panel. While it is easily pushed away, the lower edge of the retaining wall that has been pushed back is elastic again as the rising edge is hooked on the locking portion of the right panel and this locking portion moves downward. And is brought into contact with the upper surface of the horizontal wall of the locking portion of the right panel. As a result, the locking portion of the right panel is pressed by the retaining wall, and the state of being locked with the rising edge portion is firmly maintained.

EFFECT OF THE INVENTION Since the panel connecting device for the floor of the vehicle bed according to the present invention can directly and firmly connect the panels to each other, it is possible to perform hole drilling as in the case of connecting with bolts and nuts. It is unnecessary and does not add weight to the bonded panels. Also, in terms of the work of joining the panels to each other, the workability is extremely good because the left and right panels can be joined by substantially fitting them together. Further, since the coupling device of the present invention has a simple structure, it can be manufactured at a low cost, and can be widely applied to the coupling of panels such as walls (flaws) in addition to the floor for the bed of the vehicle. Is.

Further, according to the panel connecting apparatus of the present invention, the ends of the adjacent panels are fitted together and the retaining wall provided on one panel is elastically restored to the original state. Since the panels are fitted between the upper and lower end portions of the fitted panels, the panels are integrally and reliably joined together.

In addition, when it becomes necessary to separate the panels that have been joined together, the fitting between the panels can be released by elastically deforming the fitted retaining wall again with an appropriate tool. It is convenient because you can also do it.
