Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to a truck carrier wing panel that covers both left and right sides of a truck carrier.

[Prior art]

As a structure for covering the cargo bed of a truck, it has been common that a large number of gate-shaped aggregates are hung on both sides of the cargo bed and a hood is hung so as to cover them. However, in such a structure, since a large number of aggregates are fixed to both sides of the cargo bed, the cargo can be taken in and out only from the rear part of the cargo bed, and there is a problem that workability is extremely poor. Therefore, in order to solve this problem, Japanese Utility Model Publication No. 54-2496 discloses that the above-mentioned aggregate is divided into left and right parts in the central part, and the divided end parts are respectively pivotally attached to lateral beams installed in the center part in the left-right direction of the luggage carrier. Therefore, a hood having a so-called wing structure is proposed, in which the left and right aggregates can be flipped up and rotated together with the hood. And, based on the hood of such a wing structure,
A wing panel is now in widespread use, in which an aluminum panel having the functions of a hood and an aggregate is pivotally attached to a horizontal beam, and each of which can be raised upward to open the left and right sides of the luggage carrier.

Problems to be Solved by the Invention Here, the wing panel, as shown in FIG.
Each channel material a arranged at a predetermined interval is used as an aggregate and an aluminum panel b is attached to the outer surface side thereof, and an appropriate interior material c is attached to the inner surface side thereof (may be omitted). There is. For this reason, the conventional wing panel has a lot of hollow portions and is weak against external force, but it is relatively heavy and has a problem in weather resistance and corrosion resistance. Further, the thickness of the wing panel needs to be reduced in order to secure a sufficient loading width on the cargo bed where the left and right sides are covered with the wing panel. However, the conventional wing panel requires the channel material a as an aggregate. It is difficult to make it thin. For this reason, it is currently difficult to insert two pallets each having a width of 1,200 mm on the platform. Therefore, it is an object of the present invention to provide a wing panel for a truck bed that is lightweight, yet has sufficient strength, weather resistance, corrosion resistance, and can be made thin.

[Means for Solving the Problems]

For this purpose, the present invention provides a pair of left and right trucks that are pivotally attached to center beams installed in the center of the luggage carrier in the left-right direction to cover the upper and left and right sides of the luggage carrier and jump up to open the left and right sides of the luggage carrier. In a wing panel for a loading platform, it has a bent plate shape of a sandwich structure in which a core material is sandwiched between protective layers of FRP (fiber reinforced plastic), and a peripheral edge portion is held by a channel member. The feature is that it is composed of a large number of balsa wood blocks whose fiber directions are aligned in the same direction.

[Action]

Such a wing panel for a truck carrier has a bent plate shape of a sandwich structure in which a large number of balsa material blocks whose fiber directions are aligned in the thickness direction of the panel are sandwiched as a core material between protective layers of the FRP, and a peripheral edge portion is a channel member. Since it is held by, it is lightweight, yet has sufficient strength, weather resistance, touch resistance, and heat insulation performance. In addition, the core material can be easily thinned by reducing the thickness of the core material, and by doing so, a sufficient loading width on the luggage carrier can be secured. Furthermore, because the protective layer on the surface is FRP, it can be diversified in design by coloring it in an appropriate color, and the degree of freedom in design is high due to integral molding. Further, the flat surface can improve the aerodynamic characteristics of the truck.

【Example】

Hereinafter, an embodiment of the present invention will be specifically described with reference to the accompanying drawings. In FIGS. 1 to 4 showing a cab-over type truck, reference numeral 1 is a cargo bed that extends behind the cabin 2, reference numeral 3 is a pivot that is pivotably attached to both left and right sides of the cargo bed 1,
Reference numeral 4 is a pair of left and right rear panels that openably and closably covers the rear portion of the luggage carrier 1, reference numeral 5 is a roof cowl above the cabin 2, and reference numeral 6 is the upper and left and right and left sides of the luggage carrier 1 together with the above-mentioned tilt 3, rear panel 4, and roof cowl 5. A pair of left and right wing panels 6 for covering the respective parts are shown. On the other hand, as shown in FIG. 5, gate-shaped columns 7 and 8 are erected on the front and rear of the loading platform 1, and a center beam 9 is installed between the central portions of these columns 7 and 8. ing. The rear panel 4 is pivotally attached to the supporting column 8 at the rear portion of the luggage carrier 1 as a supporting member so that the rear panel 4 can be opened and closed left and right. A pair of left and right wing panels 6 are pivotally attached to the center beam 9 as a supporting member so that the wing panel 6 can be vertically rotated to open and close both left and right sides of the luggage carrier 1. The wing panel 6 is biased upward by a gas stay (not shown). As shown in FIGS. 6 to 8, the wing panel 6 is a bent plate-like member having a rounded corner 6a and bent in an L-shaped cross section, and its thickness is shown in FIG. 17.5 mm on the ceiling 6b, Fig. 10 and
The side wall portion 6c shown in FIG. 11 is set to 16 mm, and at least two pallets having a width of 1,200 mm can be inserted on the loading platform 1 so that the loading capacity on the loading platform 1 can be sufficiently secured. Here, the wing panel 6, as shown in the partially enlarged cross-sectional view of FIG. 12, is made up of a large number of block-shaped balsa materials that are cut so that both ends of the wing panel are aligned with each other in the thickness direction so that both end faces become the mouth end face. The material 10 has a plate shape of a sandwich structure in which both end surfaces of the block-shaped core material 10 are sandwiched between protective layers 11 and 12 made of acrylic resin FRP. By adopting a large number of block-shaped core materials 10 capable of following an arbitrary curvature as the core material, the wing panel 6 is protected by the protective layers 11, 12 of the FRP.
Is formed integrally with a bent plate having a round corner 6a. The entire circumference of the wing panel 6 is held by a channel member 13 made of aluminum or hard resin, and the channel member 13 and the wing panel 6 are
They are connected by a large number of rivets 14 which penetrate them. When the channel member 13 is made of hard resin, the channel member is made of an adhesive without using the rivet 14.
The 13 can be fixed to the peripheral portion of the wing panel 6. Here, a channel member along the center beam 9
As shown in FIG. 9, a square pipe 15 is welded and fixed to 13, and the channel member 13 reinforced by the square pipe 15 is joined to the center beam 9 via a hinge metal fitting 16, thus forming a pair of left and right sides. The wing panel 6 is pivotally attached so that it can be pivoted up and down to open and close both left and right sides of the luggage carrier 1. A seal tape 17 is attached to the pair of left and right wing panels 6 so as to cover the pivotally attached portion (see FIG. 2). In addition, a long plate-shaped handle 18 is fixed to the channel member 13 along the slant 3 by the rivet 14, and the channel member 13 on the front edge side of the wing panel 6 is substantially L-shaped.
A flange plate 19 having a mold section is welded and fixed, and an inverted triangular front panel 20 is fixed to the flange plate 19 by riveting. On the other hand, the slant 3 and the rear panel 4 are also constructed similarly to the wing panel 6. That is, the fan 3 and the rear panel 4 have a sandwich structure in which a block-shaped core material made of balsa material whose fiber direction is aligned in the thickness direction is sandwiched by protective layers made of FRP of acrylic resin from both sides, and its peripheral portion is made of aluminum. Alternatively, it is held by a channel member made of hard resin and is connected to the channel member by a large number of rivets. The wing panel 6 for a truck bed configured as described above is composed of the block-shaped core material 10 of balsa material and the protective layers 11 and 12 of FRP having a very small specific gravity of 0.18. Sufficient strength, weather resistance, touch resistance and heat insulation performance can be obtained. For example, its bending strength is 16
mm and the thickness of the block-shaped core material 10 is 10 mm and the thickness of the protective layers 11 and 12 of the FRP is 3 mm, 1,100 kg / cm ²
Of the order. Since such a wing panel 6 has its peripheral portion held by the channel member 13, the hinge fitting 16, the handle 18, the flange plate 19 and the like can be attached via the channel member 13. Therefore, the wing panel 6 can withstand practical use sufficiently as a structure that covers the upper and both sides of the truck bed. Further, the wing panel 6 has the above-mentioned sandwich structure, and can be easily integrally formed into a bent plate shape having a round corner of, for example, about 75R, so that the wing panel 6 is easy to manufacture and has a high degree of freedom in design. Further, the wing panel 6 can be easily thinned by reducing the thickness of the block-shaped core material 10. For example, even if the thickness is 20 mm, the loading width of the loading platform 1 covered by the left and right wing panels 6 is 2,420. It is possible to secure 2 mm of width, and by doing so, you can insert two 1,200 mm wide pallets. Further, since the wing panel 6 has a bent plate shape and the surface thereof is the protective layers 11 and 12 of FRP, the aerodynamic characteristics of the truck can be improved by applying a flat surface treatment, and the protective layer 11 on the outer surface can be improved. The design can be diversified by coloring in an appropriate color. Furthermore, in the present embodiment, the slant 3 and the rear panel 4 also have the same structure as the wing panel 6 and are lightweight, so that the weight of the entire truck is reduced. Although acrylic resin is used as the FRP for forming the protective layer 11 of the wing panel 6 or the like in the above-described embodiment, other suitable liquid resin such as polyester resin or epoxy resin may be used. Further, as the reinforcing fiber, an appropriate metal fiber other than glass fiber may be used. Further, the block-shaped core material 10 constituting the wing panel 6 or the like can be selected in an appropriate shape and size such as a strip shape, a square shape, a rectangular shape, a triangular shape, or a circular shape. The block-shaped core materials 10 may be arranged closely depending on the strength of the wing panel 6 or the location of bending work, or may be arranged with a space therebetween.

【The invention's effect】

As described above, the wing panel for a truck carrier according to the present invention has a bent plate shape having a sandwich structure in which a large number of balsa material blocks whose fiber directions are aligned in the thickness direction of the panel are sandwiched between the protective layers of the FRP as core materials. Since the peripheral portion is held by the channel member, it has sufficient strength, weather resistance, corrosion resistance, and heat insulation performance while being lightweight. Further, by making the thickness of the core material thin, the core material can be easily made thin, and by doing so, a sufficient loading width on the loading platform can be secured. Furthermore, because the protective layer on the surface is FRP, it can be diversified in design by coloring it in an appropriate color, and the degree of freedom in design is high due to integral molding. Further, the flat surface can improve the aerodynamic characteristics of the truck.
