Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a structure for mounting a top frame on a truck for integrally attaching and detaching a plurality of top frames attached to a truck bed.

Conventional technology Conventionally, the hood frames of a truck were individually fitted and supported on the side gates, so when opening the cargo bed, the hood was removed from the hood frame, and then each hood frame was removed one by one. I had to remove it. Therefore, the work is not only troublesome and time-consuming, but also has the disadvantage that the operator becomes dirty due to dust, dirt, water, etc. adhering to the canopy. Moreover, when the hood frame is distorted, it is difficult to insert and remove the hood frame, which may hinder work.

Purpose This invention was made in order to eliminate the above-mentioned conventional defects, and its purpose is to provide a new method for attaching and detaching a hood frame in a truck, which allows the attachment and detachment of the entire hood frame to be performed easily, quickly and safely. Our goal is to provide the following.

Embodiments Next, embodiments embodying this invention are shown in FIGS.
This will be explained according to FIG.

Figure 1 is a side view showing the entire truck;
1 is a pair of left and right side gates, 2 is a hood, 2a is a rubber ring for fixing the hood 2 to the chassis, 3 is a hood 2
Multiple hood frames are arranged in parallel inside the hood frame, 4 is each hood frame 3
A crosspiece 60 for maintaining the distance, which is installed between the upper parts of the hoods, is an important part of the present invention, and is a hood frame connecting member for connecting and supporting each hood frame at approximately equal intervals.

FIG. 2 is a longitudinal cross-sectional view of the top frame connecting member 60,
Pins 62 are erected at equal intervals on the upper surface of a base 61 having a U-shaped cross section and extending along the side gate 1, and a support cylinder portion 63 into which the canopy frame 3 is removably fitted is attached to the upper end of each pin 62. is fixed. Further, a pair of left and right side plates 64 having a U-shaped cross section are fixed to the lower surface of each base 61 and extending opposite to each other.

A plurality of support pins 65 are inserted and fixed at equal intervals in the longitudinal direction of both side plates 64, and each support pin 65 has a drum-shaped roller 66 formed with a small diameter at the center, which is rotatable and movable in the axial direction. is supported by Further, a rail 67 having a substantially arrow-shaped cross section extending in the longitudinal direction is screwed onto the upper surface of both side gates 1, and the rollers 66 are supported by the upper end roof portion 68 of the rail 67. As each roller 66 rolls on the rail 67, the two hood frame connecting members 60 can be moved in the front-rear direction with respect to the side gate 1.

Note that the angle of inclination of the upper surface of the roof portion 68 of the rail 67 is smaller than the angle of inclination of the central trough of the roller 66, and in the engaged state of both, there is an allowable angle α (in this embodiment, the value thereof) on both the left and right sides. teeth
9°) is formed. Therefore, when the top 2 is subjected to a crosswind or the like while the vehicle is running, the left and right tilting of the top frame 3 and the top frame connecting member 60 is allowed by the allowable angle α.

Further, a cylindrical locking fitting 70 having a notch 69 is fixed to the outer surface of the side plate 64 of the hood frame connecting member 60, and at a position directly below the locking fitting 70, the upper end of the side gate 1 is removed. A locking ring 71 is fixed to the side surface. This lock fitting 7
An L-shaped locking pin 72 is inserted into the interior of the locking pin 72 so as to be movable up and down. A retaining ring 71 is inserted therethrough. Therefore, in this state, the back and forth movement of the hood frame connecting member 60 with respect to the side gate 1 is prevented. The locking fitting 70 and the locking pin 72 constitute a fixing device. Further, when the upper end bent portion of the locking pin 72 is locked to the upper end surface of the locking fitting 70 as shown by the chain line in the figure, the lower end thereof is held in a state of not being inserted into the locking ring 71. Thus, the back and forth movement of the top frame connecting member 60 is allowed.

On the other hand, as shown in FIG. 3, a pair of left and right guide rails 74 are provided on the upper surface of the frame vehicle 73 in this embodiment, which is used when attaching and detaching the top frame 3, and have the same shape and shape as the rails 67 on the side gate 1 side. They are laid at the same intervals, and their height can be adjusted by operating an operating section 76 provided on each support column 75. Moreover, the rail 6 is provided at the upper front side of the frame car 73.
A pair of left and right connecting fittings 77 are provided for bridging the guide rail 74 and the guide rail 74.

That is, as shown in FIG. 4, a rotating plate 79 is rotatably supported by a pin 78 at the upper end of both front columns 75 of the frame vehicle 73, and the rails 67 and 74 are mounted on the upper surface of the rotating plate 79. A rail piece 80 of the same shape is fixed. When the frame car 73 and the truck are connected, the tip bent portion 81 of the rotating plate 79
are fitted into connecting rings 82 provided on the upper rear end surfaces of both side gates 1, respectively. The connecting fitting 77 is constituted by the rotating plate 79, the rail piece 80, the connecting ring 82, etc.
At the time of connection, each roller 66 rolls on the rail piece 80, and the hood frame connection member 60 is moved from the side gate 1 onto the frame car 73.

Now, the canopy frame connecting member 6 configured as described above
When opening the loading platform of a truck using the truck chassis 73, first remove each rubber ring 2a of the hood 2 from the chassis of the truck, and then open the platform vehicle 73 behind the truck as shown in FIG. Place the
Both rails 67, 74 are connected by the connecting fitting 77.
Concatenate.

Next, as shown by the chain line in FIG. 2, the locking pin 72 is pulled upward and the locking ring 7
1, the two hood frame connecting members 60 become movable relative to the side gate 1.
When the canopy frame 3 is pulled rearward in this state, each roller 66 rolls on the rail 67, rail piece 80, and guide rail 74, and the entire canopy frame 3 is moved onto the frame car 73. Therefore, in this embodiment as well, the work of removing the top frame 3 can be quickly performed by an extremely simple operation. Note that since each roller 66 is movable in the axial direction, it is possible to cope with the curvature of the side gate 1.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and may be modified as desired without departing from the spirit of the present invention.

Effects As described in detail above, in the present invention, a plurality of rollers rotatably supported by the top frame connecting member roll on the rails provided along the side gate, and the plurality of rollers rotatably supported by the top frame connecting member roll on the rails provided along the side gate. Since all the connected and supported hood frames can be moved forward and backward along the side gates, the hood frame can be easily, quickly and safely attached or removed on the truck using input. demonstrate.
