Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a luggage carrier configuration of a carrier that can easily carry and carry luggage by changing the shape of the luggage according to the luggage loaded on the luggage carrier. It is about.

(Prior Art) A carrier of a type in which the shape of a bed is changed according to the loaded object is described in Japanese Utility Model Publication No. 60-36527.

In this technology, the luggage carrier frame on one side of the luggage carrier is attached to the drawer frame, the luggage carrier is expanded by pulling out the drawer frame to the outside of the luggage carrier, and the luggage carrier frame is flattened by tilting the cargo carrier frame to be horizontal. To do.

In the above-mentioned conventional technique, when the drawer frame is stored in the cargo bed side, the other cargo bed frames adjacent to each other are held in the upright state by the columns that stand upright on both sides of the drawer frame. Since the hook and the pin are provided at the lower position of the carrier frame and the column, respectively, and the side surface of the hook is held in contact with the carrier frame, rattling occurs due to use, and sufficient carrier frame can be held. I have no ability.

Further, the hook and the pin, which are the holding devices, have to be operated every time the drawer frame is inserted and withdrawn, and the operation is complicated.

(Problems to be Solved by the Invention) This invention is intended to solve the above-mentioned drawbacks of the conventional technology.

(Means for Solving the Problem) The lower part of the carrier frame 1 is rotatably pivoted 2 and an inverted gate-shaped drawer frame 4 that is slidably drawn outward with respect to the carrier 3 is provided. On the upper parts of the columns 5 and 5 and the carrier frame 1 of 4, there are arranged a locking lever 6 and a locking member 7 capable of fixing the carrier frame 1 in an upright state,
In addition, the adjacent carrier frames 8, 8 which are rotatably supported by the carrier 3 are provided.
A carrier bed of the transport vehicle is provided with a pin 9 and an engaging hole 10 which can be inserted and removed by sliding the draw-out frame 4 at corresponding portions of the upper end and the columns 5, 5.

(Operation of the device) When it is desired to widely use the luggage carrier 3, the luggage carrier frame 1 is supported by the columns 5, 5 on both sides of the drawer frame 4 and is pulled out to the outside of the luggage carrier 3 together with the drawer frame 4 for use.

In addition, when a long object is to be loaded, the locking lever 6 is operated to release the fixation of the luggage carrier frame 1 by the struts 5, 5 on both sides of the drawer frame 4 pulled out to the outside, and the luggage carrier frame 1 is removed. Make it horizontal and hang it with a chain.

In order to hold the drawer frame 4, the pins 9 and the engagement holes 10 arranged on the upper portions of the carrier frames 8 and 8 adjacent to the stanchions 5 on both sides of the drawer frame 4 are engaged. Combined and adjacent the carrier frame 8,8
Make sure to stand and fix.

(Effect of the Invention) Since the present invention is configured as described above, the loading frame 3 can be widely used by pulling out the drawer frame 4 pivotally supporting the loading frame 1 to the outside of the loading platform 3, and further, By fixing the loading frame 1 by the columns 5, 5 on both sides of the pulling-out frame 4 pulled out to the outside, by operating the locking lever 6 to make the loading frame 1 horizontal, it is possible to easily mount long objects and the like. it can.

Further, when the drawer frame 4 is stored and held, pins 9 and engagement holes 10 which are respectively arranged on the upper portions of the support frames 8 adjacent to the drawer frames 4 and the adjacent carrier frames 8 are engaged. As a result, the loading frame 8 can be securely fixed, and the sliding of the pull-out frame 4 allows the pin 9 and the engaging hole 10 to be fitted into and disengaged from each other, so that the operation is simple.

(Example) In the illustrated example, the carrier is a crawler type traveling device 11,
It comprises a chassis 12, a loading platform 3 mounted on the chassis 12, a prime mover 13 mounted on the rear portion of the chassis 12, a control section 14 arranged on the prime mover 13, and the like.

A rear frame 25, which is a fixed carrier frame, is attached to the rear part of the carrier 3, that is, on the side of the prime mover 13, and on both sides of the carrier 3 are hinged frames 2 and 2 which are attached to the carrier 3 and are vertically movable. Both side frames 8 and 8 are provided.

Further, a drawer frame 4 is provided on the front side of the luggage carrier 3, and the drawer frame 4 is composed of a base frame 15 which is in contact with the rear end of the luggage carrier 3 and columns 5 which stand upright from both sides of the base frame 15. Left and right slide rods 1 attached to the base frame 15
6 and 16 are slidably inserted into sliding holes 17 and 17 formed in the loading platform 3. 18 is the stop bolt.

The lower part of the front frame 1 which is a carrier frame is attached to the rear part of the base frame 15 of the draw-out frame 4 by a hinge 2, and the locking levers 6, 6 are provided on both sides of the upper part of the front frame 1 and the draw-out frame 4 Locking members 7 and 7 are attached to the upper portions of the columns 5 and 5, and the front frame 1 can be fixed by engaging them. The locking lever 6 has its shaft portion 19
It is urged inward by the elastic force of the spring 20 wound around, and the elastic force is applied in the state in which the lever portion 21 that can be bent at a right angle to the shaft portion 19 is rotated upward. The shaft portion 19 is pulled out outward, the shaft portion 19 is fitted into the groove portion 22 of the locking member 7, and the locking lever 6 is rotated downward in this state so that both can be engaged. .

Pins 9 and 9 are fixed to the upper portions of the rear surfaces of the columns 5 and 5 of the drawer frame 4, and the side frames 8 and 8 corresponding to the pins 9 and 9 have engaging holes on the front surface.
10 and 10 are formed, and the side frames 8 and 8 can be held in an upright state by fitting them.

23, 23 are locking hooks, which are provided on the upper portions of the columns 5, 5 of the drawer frame 4 and the upper part of the front frame 1, and between the locking hooks 23, 23 when the front frame 1 is rotated horizontally. Hang the chain 24 on and hold it.

In a normal transportation work, the drawer frame 4 is stored on the side of the loading platform 3 and the side frames 8 and 8 and the front frame 1 are erected and fixed to carry out the transportation work.

Next, when it is desired to use the cargo bed 3 wide, the stop bolts 18 and 18 are loosened and the slide rods 16 and 16 are slid along the slide holes 17 and 17, so that the front frame 1 is pulled out together with the draw-out frame 4. Pull it forward.

Further, when carrying a long object or the like, the front frame 1 pulled out as described above is rotated horizontally and is mounted in an inclined shape between the front frame 1 and the rear frame 25 standing upright. In order to rotate the front frame 1 horizontally, first, the locking lever 6 is rotated about its shaft portion 19 and the lever portion 21 is positioned above. The engagement of the member 7 in the left-right direction is released, and the locking lever 6 slides inward in the groove portion 22 of the locking member 7 by the elastic force of the spring 20 to come off the locking member 7 and move in the front-back direction. The engagement is also released.

Next, the front frame 1 is rotated about the hinge 2 until it becomes horizontal, and then the chain 24 is hung on the locking hooks 23 and 23 to be suspended and fixed.

When the drawer frame 4 is to be stored, the set bolts 18,18
And slide the slide rods 16 and 16 along the sliding holes 17 and 17 of the loading platform 3 to dispose the pins 9 and 9 provided on the columns 5 and 5 of the drawer frame 4.
Is accommodated in the engagement holes 10 of the side frames 8 and 8 while firmly holding the side frames 8 and 8. Next, the fastening bolts 18 and 18 are tightened, the front frame 1 is pivotally raised about the hinge 2, and then the locking lever 6 is locked to the locking member 7 to fix the front frame.
