Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier frame apparatus for a transport vehicle capable of expanding a loading space according to the size and shape of a load to be loaded on the carrier.

[0002]

2. Description of the Related Art In a conventional carrier frame device,
As shown in FIGS. 5 and 6, there is a configuration in which the loading space is expanded by pulling out the loading frame 3 and 3 standing around the loading platform 1 outward.

[0003]

However, in the carrier frame device of a carrier constructed as in the prior art, the carrier frame 3 is fitted and supported by a plurality of insertion rods 4 and 4 as shown in FIG. So that when the carrier frame 3 is pulled out,
A gap A is formed between the loading surface and the carrier frame 3, causing the baggage to fall into the gap A, and soiling or damaging the baggage due to mud or stone splashing from the ground. Therefore, the operator solves the above-mentioned problem by hanging a plate material such as plywood over the gap A. However, the operator has to carry the plate material at all times, which is not efficient.

[0004]

A plurality of guide holes (2, 2) are formed in the width direction of the side surface of the carrier (1), and the insertion rods (4, 4) projecting from the lower part of the carrier frame (3) are slid into the guide holes (2). The carrier frame 3 is configured so as to be capable of moving and pulling out freely, and that the carrier frame 3 is pivotally supported so as to be able to fall inward at a lower portion when being withdrawn. Further, an auxiliary frame 5 protrudes outward from the lower part of the free-falling carrier frame 3 so as to have a configuration of the carrier frame device of the carrier according to claim 1.

[0005]

In the carrier frame apparatus according to the first aspect of the present invention, the carrier frame 3 is pivotally supported so as to be able to fall inward, so that the carrier frame 3 moves inward when it is pulled out. When it falls down, the carrier frame 3 is held horizontally on the insertion rods 4 and 4 so as to close the gap A to form a loading surface. Therefore, the loading surface can be expanded by closing the gap A only by falling the carrier frame 3 inward, so that the structure is simple and there is no need to separately carry a plate material such as plywood.

Further, in the carrier frame apparatus according to the second aspect of the present invention, since the auxiliary frame 5 projects outward from the lower part of the free-standing carrier frame 3, FIG. When the carrier frame 3 is lowered inward as shown in FIG. 7, the auxiliary frame 5 is pivoted to the vertical position and acts as a frame for preventing the load from slipping.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an example in which the carrier frame device of the present invention is applied to a crawler type carrier will be described with reference to the drawings. The crawler type transport vehicle of the present embodiment has a body frame 6 at the center of the vehicle.
A pair of left and right crawler-type traveling devices 7, 7 mounted on the vehicle body, a loading platform 1 mounted on a front portion of the vehicle body frame 6, a motor 8 mounted on a rear portion, and a steering operation section 9 on a rear side of the vehicle. The crawler type traveling devices 7 and 7 are configured by winding a crawler belt 12 between a rear driving sprocket 10 and a front tension sprocket 11, and a motor 8
Sprocket 10 that rotates and receives the power from
It is configured to be able to travel. Reference numerals 13 and 13 denote movable rolling wheels, which are rotatably supported at both ends of an arm 15 which is swingable about a support shaft 14.

Reference numerals 16 and 16 denote a pair of left and right bar handles extending rearward and upward from the rear of the body frame 6,
In the vicinity of the grips 17, 17 mounted on the rear end, side clutch levers 18, 18 for intermittently driving the crawler type traveling devices 7, 7, a throttle lever 19 for adjusting the output of the prime mover 8, and intermittent power from the prime mover 8. The steering device such as the traveling clutch lever 20 is arranged in a concentrated manner to form the steering operation unit 9. The carrier 1 has only the rear rear frame 26 fixedly attached thereto, and the front and left and right lateral carrier frames 3,
Reference numeral 3 denotes an insertion rod 4, 4 protruding from the lower part of the carrier frame 3, 3, which is inserted into guide holes 2, 2 formed on the front surface and left and right side surfaces of the carrier 1, so that it can be slid and pulled out. . 21 and 21 are knob bolts for fixing. Sliding / extractable carrier frame 3
Is a load frame base 22 that protrudes and holds the insertion rods 4 and 4.
And a main frame 23 vertically suspended on the load frame base 22 and an auxiliary frame 5 protruding outward from the lower part of the main frame 23 toward the outside of the carrier 1. The main frame 23 and the auxiliary frame 5 The L-shaped frame portion 24 to be formed is rotatably supported around a rotation support shaft 25 on the load frame base 22 so as to be able to fall down.

The auxiliary frame 5 has an angle of 90 ° with respect to the main frame 23.
When the main frame 23 in the upright state falls down inward, the auxiliary frame 5 is rotated to the vertical position. Packing frame base 22
As shown in FIG. 1, the main frame 23 protrudes outward from the rotation support shaft 25, and the main frame 23 falls outward from the hanging position by restricting the rotation of the auxiliary frame 5 by the protruding portion. To prevent them from doing so. The rotation support shaft 25 is provided at a position lower than the upper surface of the loading platform 1, and when the loading platform frame 3 is brought into contact with the loading platform 1, as shown in FIG. Is regulated to maintain the standing state.

In order to expand the space for loading the cargo on the carrier 1 in the carrier having the above structure, the carrier frame 3 held in the upright state is pulled out by loosening the knob bolts 21 and 21 on the lower surface of the carrier 1. The L-shaped frame portion 24 formed by the frame 23 and the auxiliary frame 5 is folded inward around the rotation support shaft 25 to form a loading surface having the same height as the upper surface of the loading platform 1. Fix at 21 and 21. At this time, as shown in FIG. 1C, the frame body 24 is restricted from rotating inward by the insertion rods 4 and 4 so as to close the gap A formed between the carrier 1 and the carrier frame 3. Since the main frame 23 is held on the insertion rods 4 and 4 in a horizontal state, the luggage loading surface can be easily expanded without a gap A only by lowering the carrier frame 3 inward.

The auxiliary frame 5 projecting outward from the lower portion of the main frame 23 is turned upright to the vertical position with the main frame 23 falling inward. When the luggage loading space is expanded, the luggage can be suspended around the loading surface to prevent the luggage from slipping. In this embodiment, the frame portion 2
The upright holding of 4 is restricted by the load frame base 22 protruding outward from the rotation support shaft 25 and the side surface of the loading platform 1 whose upper surface is higher than the rotation support shaft 25, so as to restrict the outward and inward fall. However, the present invention is not limited to such a configuration, and various methods may be used. For example, a configuration may be employed in which the device is erected and held by a generally used pin or hook.
Further, in the claims, numbers are written for convenience in comparison with the drawings, but the present invention is not limited to the configuration of the attached drawings by this entry.
