BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a step plate on a wall of a vehicle carrier.

[0002] In this specification, the term "aluminum" shall include aluminum alloys in addition to pure aluminum. In this specification, "inside" means the inward direction of the vehicle, and "outside" means the same outward direction. Unless otherwise specified, the bed wall is approximately 180 degrees from the upright state.
The drooping state that has been swung by degrees is referred to as a reference. Furthermore, in this specification, unless otherwise specified, the vertical direction in which the bed wall swings about 180 degrees from the upright state will be referred to.

2. Description of the Related Art A required number of hollow panels made of extruded aluminum are stacked and connected to a loading platform of a vehicle such as a large truck or the like, and the loading panel wall is mounted on a side wall of the loading platform so as to be swingable by 180 degrees. Is provided.

By the way, since the loading platform of such a vehicle is high from the ground, it is not easy for an operator to ascend or descend from the loading platform, and particularly in a place where no lift is installed, There is a problem that a great deal of labor is required for unloading and unloading luggage, and the operator is tired.

In order to solve such a problem, the applicant of the present invention firstly required a number of hollow panels made of extruded aluminum to be stacked in a required number and connected to each other. There has been proposed a cargo bed wall provided with a step plate which is movably mounted and can be easily moved up and down on a cargo bed of a vehicle (see Japanese Utility Model Publication No. 4-6995).

[0006] In the hanging state where the loading wall is swung 180 degrees from the standing state, the outer wall of the hollow panel constituting the loading wall is partially removed to form a step plate receiving recess. A step plate made of a hollow panel made of an extruded aluminum member is swingably attached to a lower portion of the inner surface of the recess by a hinge portion.

[0007]

However, in the conventional cargo carrier wall, the outer wall of the hollow panel constituting the conventional carrier wall is removed to form the step plate receiving recess, so that the strength of the hollow panel is reduced. In addition, there is a problem that the strength of the entire carrier wall is reduced. In addition, in order to load and unload cargo to and from the loading platform, it is necessary to set foot on the step board at various positions in the length direction of the loading platform wall. Since it is freely mounted, the length of the step plate needs to be equal to the length of the cargo bed wall in order to achieve the above, and there is a problem that the material cost increases.

It is an object of the present invention to provide a step board mounting structure for a vehicle carrier wall which solves the above-mentioned problem.

[0009]

SUMMARY OF THE INVENTION A step plate mounting structure for a vehicle carrier wall according to the present invention comprises a hollow panel made of an extruded aluminum material and is mounted on a vehicle carrier side wall so as to be able to swing about 180 degrees. A structure in which a step plate is removably attached to a hanging wall that swings about 180 degrees from an upright state on a bed wall of a vehicle,
The outer wall of the hollow panel constituting the loading wall is recessed to form a deep recess extending in the length direction and a shallow recess connected below the recess, and protrude upward from the lower wall of the deep recess. And a first detent portion projecting outward from the bottom wall of the shallow recess and abutting against the side surface of the step plate so as not to project beyond the outer surface of the panel. And a hook portion that engages with the upper end of the engaging wall and a second rotation stopper that contacts the bottom wall of the shallow recess at one side edge of the step plate. Things.

[0010]

The outer wall of the panel constituting the loading wall is recessed to form a deep recess extending in the longitudinal direction and a shallow recess extending below the recess, so that the outer wall is removed. Therefore, a decrease in the strength of the panel is prevented.

An engagement wall protruding upward is integrally formed on a lower side wall of the deep recess, and a first turn protruding outward on a bottom wall of the shallow recess and abutting against a side surface of the step plate. The stopper portion is integrally formed so as not to protrude from the outer surface of the panel, and a hook portion engaging with the upper end portion of the engaging wall and a bottom wall of a recess having a shallow tip are provided on one side edge of the step plate. Is provided, so that the step plate is prevented from dropping and swinging downward when the step plate is attached to the carrier wall, and the step plate is held in a horizontal state. In particular, the first detent portion integrally formed on the panel abuts against the side surface of the step plate, and the second detent portion provided on the step plate abuts on the bottom wall of the shallow recess of the panel. The downward swing of the step plate is firmly prevented.
Therefore, it becomes possible for an operator to put his / her feet on this step board and move up and down on the carrier. Moreover, since the step plate can be detachably attached to the loading wall, the step plate can be attached to an arbitrary position in the length direction of the loading wall.

The engagement wall is formed integrally with the lower wall of the deep recess, and the first detent portion is formed so as not to protrude from the outer surface of the panel. The wall and the first detent do not obstruct the cargo, and do not reduce the cargo area.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 shows a carrier wall for a vehicle. In FIG. 4, a loading wall (2) of a vehicle (1) is formed by connecting a plurality of, for example, three hollow panels (3) made of extruded aluminum in the width direction thereof and connecting them. 4 is mounted on the side wall of the loading platform (4) via a hinge (5) so as to swing 180 degrees between an upright state shown by a chain line in FIG. 4 and a hanging state shown by a solid line. A step plate (10) is mounted at an arbitrary position in the length direction of the hanging wall (4) and at the center of the height.

FIGS. 1 and 2 show a mounting structure of the step plate (10) to the loading wall (2).

In FIG. 1 and FIG. 2, a hollow panel is provided at the center of the height of the hollow panel (3) in the middle of the loading wall (2).
The outer wall (3a) of (3) is recessed, so that a deep recess (6) extending in the length direction and a shallow recess (7) extending below the recess (6) are formed over the entire length. I have. Deep depression
(6) Engaging wall (8) projecting upward from the outer edge of lower wall (6a)
Are integrally formed. In addition, the bottom wall (7
In (a), a first detent portion (9) projecting outward and abutting on the side surface of the step plate (10) is integrally formed so as not to project beyond the outer surface of the panel (3).

The step plate (10) is formed of a hollow panel made of extruded aluminum material, and has a loading wall at the upper end of one side edge thereof.
A hook (11) projecting toward (2) and engaging with the upper end of the engaging wall (8) is formed integrally. Also step board
(10) At the lower end of one side edge, a recess (7) protruding toward the loading wall (2) and having a shallow lower surface (7) in surface contact with the lower side wall (7b) and a shallow end (7) Second detent portion (12) abutting on a portion of the bottom wall (7a) below the first detent portion (9)
Are integrally formed. When the hook (11) is engaged with the engagement wall (8), the drop of the step plate (10) is prevented, and the tip of the first rotation stopper (9) is moved to the step plate.
The rotation of the step plate (10) is firmly prevented by contacting the side surface of (10) and the tip of the second detent portion (12) against the bottom wall of the shallow recess (7). By step board
(10) is held in a horizontal state. In addition, the length of the step board (10) is about 300 to 500 mm, and the width is about 150 mm.

The attachment of the step plate (10) to the carrier wall (2) is performed as follows. That is, as shown in FIG. 3, the step plate (10) is inclined so that the side edge on the side where the hook portion (11) and the second detent portion (12) are formed faces downward, and the hook The part (11) is located above and inward of the engagement wall (8). Then, the outer end of the step plate (10) is pressed downward against the loading wall (2) while rotating downward (see the arrow in FIG. 3). Then, the step board (10) is attached to the carrier wall (2) as shown in FIGS. The removal of the step board (10) from the carrier wall (2) is performed by the reverse operation.

In such a configuration, the loading wall (2) is in an upright state when the load is loaded on the loading platform (4) or in an empty state. At this time, step board
(10) has been removed from the carrier wall (2). Also, the engaging wall (8) formed integrally with the lower wall (6a) of the deep recess (6) of the hollow panel (3) and the bottom wall (7a) of the shallow recess (7) are formed integrally. Since the first detent portion (9) does not protrude beyond the outer surface of the panel (3), the load area is not reduced when the load is loaded on the loading platform (4), and the load is efficiently reduced. Can be loaded well.

On the other hand, when unloading the cargo on the loading platform (4), the loading platform wall (2) is swung 180 degrees from the standing state to the hanging state, and is placed at an arbitrary position in the length direction. The step plate (10) is attached and held in a horizontal state. Therefore, the user steps on the step board (10) and unloads the cargo on the carrier (4). If it is necessary to change the position of the foot to change the loading / unloading position with respect to the loading platform (4), shift the step board (10) to another position, or remove it once and remove it again. Install in a different location.

In the above embodiment, the loading wall (2) is formed by a plurality of hollow panels (3), but is not limited to this, and may be formed by a single hollow panel.

[0022]

According to the mounting structure of the step board on the bed wall of the vehicle of the present invention, as described above, the outer wall of the hollow panel constituting the bed wall is not removed, and the strength of this panel is reduced. Therefore, a decrease in the strength of the entire carrier wall is also prevented.

Also, when the step plate is attached to the cargo bed wall, the step plate is prevented from dropping and swinging downward, and the step plate is held in a horizontal state. It is possible to go up and down on the bed. Therefore, it is possible to easily lift and lower the loading platform, and to perform the loading and unloading work of the luggage extremely smoothly, so that the fatigue of the operator can be reduced.

Further, since the step board can be mounted at an arbitrary position in the length direction of the loading wall, the length of the step board can be kept to a minimum length necessary for putting a foot. . Therefore, the material cost is reduced.

Furthermore, in the upright state, the engagement wall and the first detent portion do not hinder the load and do not reduce the area of the loading platform, so that the load can be efficiently loaded on the loading platform.
