Description

[Detailed explanation of the idea] This invention relates to a vehicle cargo bed wall.

BACKGROUND ART In general, loading platform walls such as floors and gate walls of trucks and the like are formed by connecting a plurality of wall members made of extruded materials through bolts and bolts.

However, in this case, drilling the bolt holes is troublesome, and the weight of the truck increases due to the bolts and nuts.

This invention was made in view of the above-mentioned circumstances, and is intended to provide a vehicle loading wall that does not require troublesome work and can reduce the weight of the truck.

This invention will be specifically explained below with reference to embodiments shown in the drawings.

In addition, in this specification, the inside refers to the right side of each figure.
, ->The outside refers to the left side, and the up and down direction refers to the up and down direction in which each button can be pressed.

Referring to FIG. 1, reference numerals 1 and 2 are a pair of wall members constituting the loading platform wall according to this invention, each of which is made of extruded aluminum.

Each wall member 1.degree. 2 has extensions 3, 4 extending in opposite directions on each outer wall 1a, 2a.

Reference numeral 5 denotes a fitting groove having a U-shaped cross section provided on the inner side of the lower end of the extension part 3 of the upper wall member 1, and 6 indicates the extension part 4 of the lower wall member 2.
This is an inward fitting protrusion provided on the upper end of the holder.

By fitting the fitting protrusion 6 into the fitting groove 5, the pair of upper and lower wall members 1.degree.2 are vertically connected.

7.8 are the side walls of the pair of wall members 1 and 2, and an inward opening 9 is formed by these and the extensions 3 and 4.

10 is an upper engagement edge formed downward at the center of the width of the upper side wall 70, 11 is a lower engagement edge formed upward at the center of the width of the lower side wall 8, and 12.13 is the upper and lower side wall 7. , 8 are a pair of guiding inclined surfaces formed from the upper and lower engaging edges io, ii to the opening edges, respectively, and these are inclined so that the distance between them increases as they move inward.

14.15 denotes each inner wall Ib, 2 of the upper and lower side wall members 1, 2.
These are fitting grooves formed inwardly at the opening edges of b.

Further, in FIG. 1C, reference numeral 16 denotes a connecting member having a U-shaped cross section for fitting into the opening 9, and is made of an extruded aluminum material with high elasticity.

The vertical parts 17 of the connecting member 16 are each slightly extended in the vertical direction, and these extension pieces 18, 19 are provided with outward fitting projections 20, 21', respectively. has.

Further, the upper horizontal portion 22II'i of the connecting member 16 has an upwardly directed upper engaging ridge 23 at its tip, and the lower horizontal portion 24 has a downwardly directed lower engaging ridge 25 at its tip.

In the above configuration, when the connecting member 16 is first pushed into the opening 9 in each horizontal portion 22, 24' (i = 1), as shown in the opening in FIG. Article 20.2
1 is fitted into the fitting grooves 14 and 15 of the inner walls 1b and 2b, and the upper and lower engaging protrusions 23 and 25 are inserted into the opening 9 along the inclined surfaces 12 and 13 of the upper and lower side walls 7 and 8. It is press-fitted and tightly engages with each of the engaging edges 10.11 of the upper and lower side walls 7.8, and also fits into the gap 26 between the lower engaging edge 11 and the fitting groove 5.

In this way, the pair of wall members 1 and 2 are connected.

FIG. 2 shows a second embodiment of this invention.

In this example, the fitting groove 5 and the fitting protrusion 6 are constructed in the same manner as in the first embodiment, but the lower side wall 8 does not have an inclined surface, and the lower engaging edge 11 is formed on the side wall 8. It forms an obtuse angle to.

The lower fitting groove 15 is shaped to curve outward and diagonally downward to have an arc shape in cross section, and the lower fitting protrusion 21 is also curved to have an arc shape in cross section so as to conform to the groove groove 15. There is.

Further, the lower engaging protrusion 25 also forms an obtuse angle with respect to the horizontal portion 24.

In this case, as shown in the opening of the figure, first, the lower fitting protrusion 21 is fitted into the lower fitting groove 15, and then the upper engaging protrusion 23 is slid on the inclined surface 12. When the connecting member 16 is pushed into the opening 9, the lower engaging protrusion 25 fits into the gap 26 between the lower engaging edge 11 and the fitting groove 5.

In the embodiment shown in FIGS. 1 and 2, the lower engaging protrusion 25 presses outward the fitting part 27 consisting of the fitting protrusion 6 and the fitting groove 5 fitted in the inner and outer directions. , prevents the fitting protrusion 6 and the fitting groove 5 from separating.

Note that other reference numerals in FIG. 2 indicate the same members as those with the same reference numerals in FIG.

The button fitting grooves 14 and 15 and the fitting protrusions 20 and 21 that fit into these buttons are not essential.

Since the vehicle cargo bed wall according to this invention has the above-mentioned structure, the wall members 1 and 2 can be reliably connected via the connecting member 16 with a simple operation, and in this case Since bolts and nuts are not used, the weight of the truck does not increase.

Furthermore, since the fitting portion 27 consisting of the grooved line 5 and the protruding line 6 that are fitted in the inner and outer directions is pressed outward by one of the protruding edges 23 and 25, the fitted grooved line 5 and the protruded line 6, There is no or no separation due to vibration or the like, so that the fitting can be reliably maintained and the connection can be made strong, and the looseness of the fitting portion can be completely eliminated.
