Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle carrier structure and a vehicle, and more particularly to a carrier structure capable of increasing variations in a method of securing and moving a load on the carrier, and a vehicle including the carrier structure.

Hooks for fixing ropes and lashing belts are attached to the bed of vehicles such as general trucks. In addition, a rod-shaped column called a stanchion is erected in a plurality of holes provided in the luggage carrier, or a lantern placed on the luggage carrier is supported by a stanchion to prevent movement of luggage during traveling.
For example, Patent Document 1 discloses a structure in which an annular hook (rope hooking member) is supported by a supporting member so as to stand upright on the floor surface. The hooks are arranged at equal intervals in the front-rear direction on the left and right edges and the center of the luggage carrier.
Here, for example, one rope may be hung on the left rear hook and the right front hook, and the other rope may be hung on the left front hook and the right rear hook to fix the luggage with a rapture. is there. In such a case, a tensile force acts diagonally upward on each hook and each support member, and a crack may be generated in the hook and the support member due to repeated load caused by vibration during traveling.
Further, since the hook in the upright state projects from the floor surface, there is a problem that it becomes an obstacle when loading and unloading luggage.

Therefore, for example, in Patent Document 2, a U-shaped groove extending in the front-rear direction is fixed to the upper surface of the lateral joist of the truck, and a large number of bar members (hooks) are fixed inside the U-shaped groove at equal intervals in the front-rear direction. Is disclosed. A flange extending in the horizontal plane is formed at the upper end of the U-shaped groove, and the flange and the floor surface are flush with each other (see FIGS. 1 to 3 of Patent Document 2).
According to the structure of Patent Document 2, since the hook is not movable but is fixed in the U-shaped groove, it is possible to reduce the possibility that the hook will be broken even when a tensile force acts diagonally upward. Further, since the hook does not protrude from the floor surface, it does not interfere with loading and unloading of luggage.

However, the above conventional technique has the following problems.
That is, in the technique of Patent Document 1, since the hook is fixed to the upper surface of the horizontal joist (the erection member) with a bolt or the like, the hook can be attached only to the position where the lateral joist is present, which is a method for securing luggage. There is a problem of limitation.
Further, in the technique of Patent Document 2, the U-shaped groove is fixed to the upper surface of the lateral joist with bolts and the flange and the floor surface are flush with each other as described above. Therefore, the depth of the U-shaped groove can be secured only to the same level as the thickness of the floor panel (support panel), and the gap formed between the bottom of the U-shaped groove and the hook is narrowed, and a thick rope or There is a problem that it is difficult to pass the lashing belt through the gap.
In addition, since the stanchion is used by inserting it into the hole provided in the luggage carrier in advance, it is difficult to freely change the position of the stanchion according to the type and size of the luggage, and the method of preventing movement of the luggage is limited. There is also a problem that occurs.

  In view of such problems, it is an object of the present invention to provide a luggage carrier structure that can increase variations of the method of securing luggage and the movement prevention method, and a vehicle including the luggage carrier structure.

The luggage carrier structure of the present invention is a rail having a U-shaped cross section consisting of a bottom plate extending in the front-rear direction of the truck and two side plates extending upward from the left and right ends of the bottom plate, and the left and right ends being joined to the inner surfaces of the two side plates. The rail is provided with two flanges extending inward at the upper ends of the two side plates, and the rail is formed by cutting out the upper side of the end of the lateral joist of the track. a shall be arranged in a recess made, the recess are those made by cutting the stepped upper bunk end of said transverse joists, side skirts are arranged in the first stage of the recess By doing so, the upper side of the side skirt and the second step of the concave portion are flush with each other, and the bottom plate is placed on the flush surface, and the rod-shaped hook is in the front-back direction in the rail. It is characterized in that a plurality is arranged.
Further, it is provided with an L-shaped stanchion composed of a rod-shaped main body extending in the vertical direction and a locking portion extending horizontally from the lower end of the main body, and the locking portion is provided between the bottom plate and the rod-shaped hook. It is characterized in that the L-shaped stanchion is locked in an upright state with respect to the loading platform by being inserted into the gap formed in.
A vehicle of the present invention is characterized by including the above-described luggage carrier structure.

In the luggage carrier structure and the vehicle of the present invention, the recesses are formed by notching the upper portions at the left and right ends of the horizontal joist, and the rails having a U-shaped cross section are arranged in the recesses. Therefore, it is not necessary to make the depth of the rail approximately the same as the thickness of the floor panel on the horizontal joist as in the conventional case. In other words, the depth of the rail can be the length obtained by adding the thickness of the floor panel and the depth of the recess. As a result, the height of the gap formed between the bottom plate of the rail and the rod-shaped hook can be increased, and a thick rope or lashing belt can be easily passed through the gap.
In the present invention, a plurality of rod-shaped hooks are arranged inside the rail arranged in the recess. The position of the rod-shaped hook can be freely changed at the time of design as long as it is inside the rail. That is, since it is not necessary to match the position of the rod-shaped hook with the position of the horizontal joist as in the conventional case, it is possible to increase the variation of the method of securing the load.
Further, when using the L-shaped stanchion, the L-shaped stanchion can be locked to the luggage carrier in an upright state simply by inserting the locking portion into the gap. Since a large number of rod-shaped hooks are arranged in the rail, the user can freely change the position of the L-shaped stanchion according to the type and shape of the luggage, and increase the variation of the luggage movement prevention method.

[First Embodiment]
A first embodiment of a luggage carrier structure and a vehicle of the present invention will be described. In the following description, the traveling direction of the vehicle will be referred to as “forward”. Further, since the luggage carrier structure is approximately bilaterally symmetric, the left luggage carrier structure will be mainly described. In the present embodiment, the vehicle is a truck provided with a tilt, but the luggage carrier structure of the present invention can be applied to all vehicles having a luggage carrier such as a van.

As shown in FIGS. 1 to 3, the luggage carrier structure of the present embodiment is roughly configured by a lateral joist 10, a rail 20, a rod-shaped hook 30, and the like.
A tilt 3 is rotatably supported on the carrier 1 by a hinge (not shown) attached to a side skirt 2 having an L-shaped cross section. Further, the vertical joist 4 and the lateral joist 10 are connected by a connecting plate 5.

A plurality of lateral joists 10 are arranged at intervals in the front-rear direction of the vehicle. In this embodiment, a square pipe having a quadrangular cross section is used as the horizontal joist 10, but the shape of the lateral joist 10 is not particularly limited, and the cross section has a substantially L shape, an I shape, a T shape, It may be H-shaped, U-shaped or the like. Further, the material of the horizontal joist 10 is not particularly limited, and general materials such as steel, aluminum and aluminum alloy can be used.
A recess 11 is formed by cutting out the upper side of the end of the lateral joist 10. Specifically, as shown in FIG. 3, the recess 11 is formed by notching the end of the lateral joist 10 in a two-step shape when viewed from the front. By disposing the side skirt 2 on the first step 11a of the recess 11, the upper side of the side skirt 2 and the second step 11b are flush with each other, and the bottom plate 21 of the rail 20 is placed thereon. The side skirt 2 and the rail 20 are fixed to the luggage carrier 1 by well-known means such as bolts and nuts or welding.

The rails 20 are members arranged on both left and right edges of the luggage carrier 1. The rail 20 is formed in a substantially U-shaped shape by a bottom plate 21 extending in the front-rear direction and two side plates 22 extending upward from the left and right ends of the bottom plate 21.
At the upper ends of the two side plates 22, flanges 23, 24 extending inward are formed. The flanges 23, 24 are designed to be flush with the surface of the floor panel 40. The floor panel 40 is arranged on the upper surface of the lateral joist 10 with its side surface abutted against the outer surface of the side plate 22, and is fixed by a known means.
In addition, that the cross-sectional shape of the rail 20 is “U-shaped” means that at least a bottom plate 21 and two side plates 22 rising from the left and right of the bottom plate 21 have a U-shaped portion. Therefore, even when the flanges 23, 24 and other parts are provided on the rail 20, the cross-sectional shape of the rail 20 is included in the "U shape".

The rod-shaped hooks 30 are members arranged in the rail 20 in the front-rear direction. The left and right ends of each rod-shaped hook 30 are joined to the inner surfaces of the two side plates 22.
Although the rod-shaped hooks 30 are arranged at regular intervals in the front-rear direction in the present embodiment, the present invention is not limited to this, and the intervals may be changed. Further, the rod-shaped hook 30 may use either a round bar or a square bar.
The material of the rail 20 and the rod-shaped hook 30 is not particularly limited, and a general material such as steel, aluminum, aluminum alloy (for example, hot-dip zinc-aluminum-magnesium alloy plated steel sheet), stainless steel or the like can be used.

[Second Embodiment]
Next, a second embodiment of the luggage carrier structure and the vehicle of the present invention will be described. The parts having the same configurations as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.
As shown in FIG. 4, the luggage carrier structure of the present embodiment is characterized in having an L-shaped stanchion 50.
The L-shaped stanchion 50 includes a rod-shaped main body 51 extending in the vertical direction and a locking portion 52 extending horizontally from the lower end of the main body 51.
The material of the L-shaped stanchion 50 is not particularly limited, and general materials such as steel, aluminum, aluminum alloy, and stainless can be used.
