Description

  The present invention relates to a vehicle bed structure and a vehicle, and more particularly to a bed structure that can increase variations in a method for securing a load on a load bed and a method for preventing movement, and a vehicle including the bed structure.

A hook for fixing a rope or a lashing belt is attached to a loading platform of a vehicle such as a general truck. In addition, a rod-like pillar called a stanchion is set up in a plurality of holes provided in the cargo bed, and a phosphorus tree placed on the cargo bed is supported by the stanchion to prevent the movement of the luggage during traveling.
For example, Patent Document 1 discloses a structure in which an annular hook (rope hanging member) is supported by a support member so as to be able to stand up with respect to a floor surface. The hooks are arranged at the left and right side edges and the center of the loading platform at equal intervals in the front-rear direction.
Here, for example, one rope is hung on the left rear hook and the right front hook, and the other one rope is hung on the left front hook and the right rear hook, thereby fixing the luggage by hanging. is there. In such a case, a tensile force acts obliquely upward on each hook and each support member, and the hook and the support member may be cracked due to repeated loads caused by vibration during traveling.
In addition, since the hook in an upright state protrudes 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 on the upper surface of the horizontal joist of the track, and a large number of rod members (hooks) are fixed at equal intervals in the front-rear direction inside the U-shaped groove. Is disclosed. A flange extending in a 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 and is fixed in the U-shaped groove, the possibility of the hook being broken even when a tensile force acts obliquely upward can be reduced. Moreover, since the hook does not protrude from the floor surface, it does not get in the way when loading and unloading luggage.

JP 2000-255316 A JP 60-92941 A

However, the above prior art 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 (construction member) with a bolt or the like, the hook can be attached only to the position where the horizontal joist exists, There is a problem of limitations.
In the technique of Patent Document 2, as described above, the U-shaped groove is fixed to the upper surface of the horizontal joist with a bolt or the like, and the flange and the floor surface are flush with each other. Therefore, the depth of the U-shaped groove can only be secured 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 becomes narrow, There is a problem that it is difficult to pass the lashing belt through the gap.
In addition, since the stanchions are used by being inserted into holes provided in the loading platform in advance, it is difficult to freely change the position where the stanchions are set up according to the type and size of the baggage, limiting the method for preventing baggage movement. There is also a problem that occurs.

  In view of such problems, an object of the present invention is to provide a cargo bed structure capable of increasing variations of a luggage securing method and a movement prevention method and a vehicle including the cargo bed structure.

The loading platform structure according to the present invention has a U-shaped cross section composed 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 both left and right ends joined to the inner surfaces of the two side plates. The rail is disposed in a recess formed by cutting out the upper side of the end of the horizontal joist of the track, and a plurality of the rod-shaped hooks are disposed in the front-rear direction in the rail. Features.
In addition, it has an L-shaped stanchion consisting of a rod-shaped main body portion extending in the vertical direction and a locking portion extending in the horizontal direction from the lower end of the main body portion, and the locking portion is located between the bottom plate and the rod-shaped hook. The L-shaped stanchion is locked in a standing state with respect to the cargo bed by being inserted into the gap formed in the base plate.
Moreover, the vehicle of this invention is provided with the said bed structure.

In the loading platform structure and the vehicle according to the present invention, a recess is formed by cutting out the upper portions of the left and right ends of the lateral joists, and a U-shaped rail is disposed in the recess. Therefore, it is not necessary to make the depth of the rail the same as the thickness of the floor panel on the side joist as in the prior art. That is, the depth of the rail can be set to a length obtained by adding the thickness of the floor panel and the depth of the recess. Thereby, the height of the gap formed between the bottom plate of the rail and the rod-like 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-like 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 within the rail. That is, since it is not necessary to match the position of the rod-like hook with the position of the horizontal joist as in the conventional case, variations in the method of securing the luggage can be increased.
In addition, when using an L-type stanchion, the L-type stanchion can be locked to the cargo bed in an upright state simply by inserting the locking portion into the gap. Since a large number of rod-like 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 load, and the variation of the load movement prevention method can be increased.

[First embodiment]
A first embodiment of a cargo bed structure and a vehicle according to the present invention will be described. In the following description, the traveling direction of the vehicle is expressed as “front”. Further, since the cargo bed structure is substantially symmetrical, the left cargo bed structure will be mainly described. In this embodiment, the vehicle is a truck having a tilt, but the cargo bed structure of the present invention can be applied to all vehicles having a cargo bed such as a van.

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

A plurality of horizontal joists 10 are arranged at intervals in the longitudinal direction of the vehicle. In the present embodiment, a square pipe having a rectangular cross section is used as the horizontal joist 10, but the shape of the horizontal joist 10 is not particularly limited, and the cross section is substantially L-shaped, I-shaped, T-shaped, It may be H-shaped or U-shaped. Further, the material of the lateral joists 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 horizontal joist 10. Specifically, as shown in FIG. 3, when viewed from the front, the end portion of the lateral joist 10 is cut out in a two-step shape to form the recess 11. Then, by arranging 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 each fixed to the loading platform 1 by well-known means such as bolts / nuts or welding.

The rails 20 are members disposed on the left and right side edges of the loading platform 1. The rail 20 is formed in a substantially U-shaped cross section 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.
Flanges 23 and 24 extending inward are formed at the upper ends of the two side plates 22. The flanges 23 and 24 are designed to be flush with the surface of the floor panel 40. The floor panel 40 is disposed on the upper surface of the lateral joist 10 with its side face being abutted against the outer surface of the side plate 22, and is fixed by a known means.
Note that the cross-sectional shape of the rail 20 being “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 are provided with 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-type”.

A plurality of rod-like hooks 30 are members arranged in the front-rear direction in the rail 20. The left and right ends of each rod-shaped hook 30 are joined to the inner surfaces of the two side plates 22.
In the present embodiment, the rod-like hooks 30 are arranged at regular intervals in the front-rear direction. However, the present invention is not limited to this, and the intervals may be varied. The rod-like hook 30 may be 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 general materials such as steel, aluminum, an aluminum alloy (for example, a hot dip zinc-aluminum-magnesium alloy plated steel plate), and stainless steel can be used.

[Second Embodiment]
Next, a cargo bed structure and a second embodiment of the vehicle according to the present invention will be described. The same reference numerals are given to portions having the same configuration as the first embodiment, and the description thereof will be omitted.
As shown in FIG. 4, the bed structure according to the present embodiment is characterized in that an L-type stanchion 50 is provided.
The L-shaped stanchion 50 includes a rod-like main body 51 extending in the vertical direction and a locking portion 52 extending in the horizontal direction from the lower end of the main body 51.
The material of the L-type stanchion 50 is not particularly limited, and general materials such as steel, aluminum, aluminum alloy, and stainless steel can be used.

5 and 6 show the usage state of the L-shaped stanchion 50. FIG.
The user lowers the locking portion 52 between the two rod-like hooks 30 (FIG. 6 (a)), and then against the gap 25 formed between the bottom plate 21 of the rail 20 and the rod-like hook 30. The locking part 52 is inserted from the rear side (FIG. 6 (b)). As a result, the L-shaped stanchion 50 is locked in a standing state with respect to the loading platform 1 (FIG. 6 (c)). Note that the locking portion 52 may be inserted into the gap 25 from the front side.
When the vehicle starts / stops / turns left / right / accelerates / decelerates, inertial force acts in the direction to defeat the L-type stanchion 50. However, since the locking portion 52 is fitted in the gap 25 and the inclination of the locking portion 52 is regulated by the rod-shaped hook 30 and the left and right side plates 22, the L-shaped stanchion 50 does not fall down.
The user places an L-shaped stanchion 50 at an arbitrary position on the left and right rails 20 of the loading platform 1 and supports the Rinki (not shown) placed on the loading platform 1 with the two L-shaped stanchions 50. Can be prevented from moving. Rinki is not necessarily used.
The location where the L-shaped stanchions 50 are disposed may be changed as appropriate according to the type and shape of the luggage, and a plurality of L-shaped stanches 50 may be disposed on one rail 20.
Alternatively, a hole penetrating in the vertical direction may be provided in a part of the rail 20, and a conventional linear (I-type) stanchion may be fitted into the hole. Further, as shown in FIG. 5, the loading platform structure of the present invention can be used in combination with a conventional annular hook 60.

  The present invention relates to a cargo bed structure capable of increasing variations in a method for securing a load and a method for preventing movement, and a vehicle including the cargo bed structure, and has industrial applicability.
