Abstract

PURPOSE:To ensure bridge mounting onto the rear body, etc., of a vehicle and increase the degree of freedom for the location of the grounding part by inserting an anchor bar in a receptacle hole in a high position surface through a through-hole provided in the top end of a bridge which is set over the high position surface and low position surface of a stepping part, and mounting the bridge rotatably within a plane. CONSTITUTION:A receptacle hole admitting the insert part 1b of an anchor bar 1 is furnished at the rear end face of, for example, the rear body of a truck in such an arrangement as located identical to a through-hole 7 provided in a bridge 4, and the anchor bar 1 is set free from a mounting member and inserted in the receptacle hole upon passing through the through-hole 7, and thereby the bridge 4 can be mounted rotatably round the receptacle hole. As a result, the plane position of the bottom grounding part of the bridge 4 becomes free in sector form, and the location of the grounding part can be made any as desired. The mounting member 2 is welded fast to a stepping member 6 on the end plate 8 formation side, which liberates the anchor bar 1 nipped by the mounting member 2 from risk of falling or being left as it is.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention extends from a high-position surface to a low-position surface and from a low-position surface to a high-position surface by bridging between a high-position surface and a low-position surface of a step portion having a height difference. The present invention relates to a method and an apparatus for attaching a bridge used when moving an agricultural machine such as a tractor and a combine, a construction machine, an industrial machine, and a motorcycle to such a step.

[0002]

2. Description of the Related Art Conventionally, when bridging such a bridge between, for example, a truck bed and the ground, a hook-shaped member is provided at the tip of the bridge and the hook-shaped member is provided. It was attached by locking it at the edge of the platform. However, in such a mounting method, the positional relationship between the bridge and the track is fixed, so that the bridge is difficult to handle and therefore workability is poor.

[0003]

As a result of various studies in view of the above problems, the present invention provides a method for mounting a bridge, which facilitates handling of the bridge, and an apparatus which facilitates mounting the bridge.

That is, according to the method of the present invention, the through hole formed at the upper end of the bridge that bridges between the high position surface and the low position surface of the stepped portion having a height difference is used to receive the receptacle formed on the high position surface. The bridge is rotatably mounted in a plane by inserting an anchor bar into the hole.

Further, in the device of the present invention, the through hole formed in the upper end portion of the bridge bridging between the high position surface and the low position surface of the step portion having the height difference and the receiving hole formed in the high position surface. And an anchor bar which is inserted into the receiving hole through the through hole to rotatably mount the bridge in a plane, and an anchor bar mounting member which removably mounts the anchor bar to the bridge. At this time, it is effective to fix the anchor bar mounting member that elastically clamps a part of the anchor bar to the bridge.

EXAMPLES Next, the present invention will be explained based on examples.

As shown in FIG. 1, as the anchor bar (1), T-shaped round steel was used. In the illustrated anchor bar, the handle portion (1a) and the insertion portion (1b) are both made of round steel, but the handle portion (1a) may be a square steel material or a spherical shape, and the handle portion (1a ) And the insertion part (1b) may be L-shaped.

Further, as shown in FIG. 2, a mounting member (2) for detachably mounting the anchor bar is made of an elastic material such as a stainless steel plate, and the plate is bent into a substantially triangular cross section and the anchor bar ( 1) The insertion part (1b) of (1) is provided with an outwardly curved R part (2a) so that it can be clamped from both sides, and an opening (2b) is opened at the upper end for inserting the insertion part (1b) of the anchor bar.
Is formed. In the figure, (3) is a bolt hole that can be used when attaching the mounting member (2).

FIG. 3 shows a state in which such an anchor bar (1) is attached to the mounting member (2). However, in the drawing, the structure is such that the insertion portion (1b) of the anchor bar is detachably clamped, but it is also possible to use a mounting member configured to clamp another portion, for example, the grip portion (1a).

Next, a bridge for mounting the mounting member will be described. As shown in FIG. 4, the bridge (4) is formed by fixing a plurality of step members (6) at predetermined intervals in the longitudinal direction between opposing side wall surfaces of frame members (5) and (5 ′) parallel to each other. A through hole (7) for inserting the anchor bar (1) at one end in the longitudinal direction to be placed on the high position surface side when it is used by straddling between the high position surface and the low position surface of the step portion. ) Is provided on the end plate (8). Further, the mounting member (2) was welded and fixed to the end plate (8) side surface of the step material (6) on the side where the end plate (8) was formed. If the mounting member (2) is fixed to the bridge (4) in this way, the anchor bar (1) held by the mounting member (2) is forgotten or dropped somewhere when the bridge is moved. It's convenient because it does not happen This mounting member may be fixed not only to the position shown in the drawing but also to the outer surface of the frame material (5 ') of the bridge shown by A in the drawing. You may screw it on.

In order to bridge such a bridge between, for example, the truck bed and the ground, as shown in FIG. 5, the insertion portion (1b) of the anchor bar (1) is attached to the rear end surface of the truck bed (9). ) Into which a receiving hole (not shown) can be inserted, and the receiving hole and the through hole (7) of the bridge are aligned and the anchor bar (1) is removed from the mounting member and received through the through hole (7). Inserting into the hole allows the bridge to be rotatably mounted around the receiving hole.

By attaching the bridge to the truck carrier (9) in this way, the plane position of the lower end grounding portion of the bridge can be freely made into a fan shape, so that, for example, when the two-wheeled vehicle is lifted to the carrier (9), The position of can be changed arbitrarily and is convenient. In addition, by laying two such bridges in parallel with the truck bed, it is convenient for loading and unloading tractors, combines, other agricultural machines with rubber tires or rubber or iron crawlers, construction machines, etc. on the truck bed. Available for

[0013]

As described above, according to the present invention, the bridge is surely attached to the truck bed or the like, and the degree of freedom of the position of the ground portion of the bridge is high. It has excellent effects such as simple and reliable storage.
