Description

[Detailed description of the invention] This invention relates to the improvement of a pallet trolley, which is mainly used on the loading bed of a truck. To provide a pallet truck with a stopper which is equipped with a stopper to prevent cargo placed thereon from moving and which can be easily operated.

Recently, trucks have become larger, and pallets and carts on which the pallets are placed are used to place cargo on the loading platform.

However, since conventional trolleys do not have stoppers, there is a drawback that the cargo moves along with the trolley on the loading platform, causing damage to the cargo.

In view of this point, the proposed pallet truck with a stopper was devised, and the pallet truck with a stopper of the present invention supports a large number of rollers between a pair of frames in a freely rotatable manner, and also supports the rear end and tip of the frame or the rear end of the frame. A sliding body is formed by fixing a pair of guide plates facing each other between the ends and arbitrary rollers, and a friction body is provided at the bottom where an upward force is constantly exerted by a spring. , the sliding body is fitted between the guide plates so as to be able to freely move up and down, and a freely rotatable shaft is formed between the pair of frames, and a freely rotatable roller is interlocked with the shaft via a support. The gist of the present invention is that the sliding body is moved downward against a spring by a freely rotatable roller interlocked with a support body and a connecting rod, so that the friction body is brought into contact with the ground.

Next, an embodiment of the stopper-equipped pallet truck according to the present invention will be described based on the drawings.

First, the main body of the pallet truck will be explained.

Ia and 1b are movable bodies having the same structure, and the movable bodies 1a,
1b is constructed as follows.

That is, 2a and 2b are a pair of parallel frames, and a large number of rollers 3 are freely rotatable between the frames 2a and 2b.
It is configured by attaching.

As a result, the moving bodies 1a and Ib are arranged in a row in parallel.
1b are connected and fixed in a detachable manner by means of a support rod 4.

Further, 5at5b, 6at6b, 7at7b, and 8ay8b are guide plates each having a narrow width, and each guide plate is attached at an arbitrary position between the rear ends of the frames 2a and 2b and the roller 3, or with the rear end, as shown in the figure. The tips (not shown) are fixed to the inner sides of the frames 2a and 2b vertically and facing each other with a gap between them.

The pallet truck body A is constructed as described above.

Further, 9a, 9b and 10a, 10b are a pair of sliding bodies, respectively. The sliding body 9a is connected to the guide plates 5a, sb, the sliding body 9b is connected to the guide plates 6a, 5b, and the sliding body 10a is connected to the guide plates 7a, 7b. , and the sliding body 10b is a guide plate 8a,
The guide plates 5a p 5b p6a, 6 move up and down along the frames 2a, 2b guided by the guide plate sb.
b.? a, 7b and 8a, and ob, and the sliding bodies 9a, 9b and 10a p 1
A friction body 11 made of, for example, a rubber plate is fixed to the lower part between the frames 2a and 0b via a seat plate 12, and a straight line extending perpendicularly to the frames 2a and 2b is provided at the center of the upper surface of the seat plate 12. A substantially square-shaped recess 13 is formed.

Moreover, 14 is a long groove formed in the vertical direction at the center of the upper part of the sliding bodies 9at9b, 10a, and 10b.

Reference numeral 15 designates a total of eight lower retaining pins which are screwed and fixed to opposite sides of the two seat plates 12, respectively.

Reference numeral 16 designates a total of eight upper stop pins screwed and fixed to the upper part of each guide plate, including the upper stop pin 16 and the lower stop pin 15.
A tension spring 17 is provided between each of them.

Therefore, the sliding bodies 9a, 9b and 10a, 10b always have
There is an upward force at work.

Further, 18a and 18b are freely rotatable shafts that protrude into the long groove 14 and have both ends supported by the frames 2a and 2b,
A pair of support plates 19a, 19b and 20a, 20b are fixed to the shafts 18a, 18b at intervals such that they are located between the frames 2a, 2b, respectively.

Support plates 19a, 19b and 20a are provided at both ends between the support plates 19a, 19b and 20a, 20b.

The rollers 21a and 21b supported by the shaft 1
It is provided so as to be freely rotatable so as to be located below 8a and 18b.

Further, above the shafts 18a, 18b, support plates 19a, 19b
and 20a.

Freely rotatable round shafts 22a and 22b are provided between the rollers 21a, the shaft 18a, and the round shaft 22a.
The centers of the roller 21b, shaft 18b, and round shaft 22b are located on the same line.

Further, both round shafts 22a and 22b are connected by a connecting rod 23.

Further, reference numeral 24 denotes a locking body radially fixed to the rear end side shaft 18a.

Therefore, when rotating the shaft 18a via the locking body 24, the support plates 19a, 19b, and the connecting rod 23 and the shaft 18b
The support plates 20a and 20b rotate in the same manner, and the rollers 21a and 21b also rotate in the same manner.

Therefore, the rollers 21a and 21b rotate from the position shown in FIG. 3 where they do not face the recess 13 to the position shown in FIG. When the sliders 22b become vertical, the sliders 9a, 9b and 10a, 1ob move downward against the tension spring 17 via the rollers 21a and 21b, so that the friction member 11 comes into contact with the ground.

That is, the friction body 11 becomes a stopper.

However, as mentioned above, the shafts 18a and 18b are connected to the sliding bodies 9a and 9.
Since the shafts 18a and 18b are located within the longitudinal grooves 14 formed in the sliding bodies 9a and 9,
This does not interfere with the downward movement of b, 10a, and 10b.

Also, when the shafts 18a and 18b rotate, the rollers 21a,
Since the shaft 21b rotates while rotating on the upper surface of the seat plate 12, there is little resistance and the shafts 18a and 18b can be rotated with a small amount of force.

Further, as described above, the shafts 18a, 18b and the roller 21a,
When the rollers 21a and 21b become vertical, the rollers 21a and 21
It is designed so that the vicinity of the lower end of b protrudes into the approximately ■-shaped recess 13 as described above, and the sliding bodies 9a, 9
b, 10a, and 10b have tension springs 1 as described above.
Since an upward force is always exerted by roller 2, roller 2
1a.

There is no risk that the friction body 21b will accidentally jump out of the recess 13, and the grounding state of the friction body 11 is firmly maintained.

Also, as mentioned above, the sliding bodies 9a, 9b and 10a.

There is always an upward force acting on axis 10b, but axis 1
8a and 18b are sliding bodies 9a, 9b and 10a.

It plunges into the long groove 14 formed in the upper part of the shaft 18a.
, 18b are in contact with the bottom of the long groove 14, so there is no risk of the sliding bodies 9a, sb and 10a, 10b flying upward.

Further, since the round shafts 22a and 22b are connected by the connecting rod 23, when the shaft 18a is rotated via the locking body 24 as described above, the shaft 18b is rotated.In other words, the roller 2
1b rotates.

That is, the rollers 21a and 21b move in the same manner.

The pallet truck with a stopper according to the present invention is constructed as described above, and the method of use and operation and effects thereof will be explained below.

At this time, as is clear from FIG. 3, the sliding bodies 9a, sb, and 10a are used to transport the cargo to a desired location on the truck bed together with a pallet truck equipped with a stopper.

10b is pulled upward by a tension spring 17, and in other words, a roller 3 is placed between the friction body 11 and the loading platform.
Since the design is such that a gap d is formed between the rollers 3 and 3, the load can be easily transported to the desired position by the multiple rollers 3.

Next, the end of a lever (not shown) is inserted and fixed into the locking body 24, and the locking body 24 is pressed downward via the lever.

Then, the shaft 18a to which the locking body 24 is fixed and the support plates 19a and 19b to which the shaft 18a is fixed rotate, and the round shaft 22a is rotated.
rotates.

Further, the round shaft 22b rotates on the round shaft 22a via the connecting rod 23, and the support plates 20a and 20b rotate.

This rotation of the support plate causes the roller 21b to rotate.

That is, the rollers 21a and 21b move in an arc while rotating, and at the same time the rollers 21a and 21b and the shafts 18a and 18b become vertical, respectively, the rollers 21a and 21b rush into the approximately ■-shaped recess 13 and are locked. .

This operation causes the rollers 21a and 21b to move to the sliding body 9a.
, sb and 10a, 10b are moved downward against the tension spring 17, so that the friction body 11 comes into contact with the ground.

In this state, as is clear from FIG. 4, the roller 3 is designed to be located above the loading platform by the gap d, so the load of the cargo is entirely applied to the two friction bodies 11, and the friction bodies 11 The resistance between the load and the load platform acts as a dog, increasing the braking ability and keeping the load immobile.

That is, by using the pallet truck with a stopper according to the present invention, it is possible to prevent cargo from moving together with the truck on the bed of a truck.

Further, the vertical movement of the friction body is extremely simple since it is only necessary to rotate the shaft 18a via the locking body.

As is clear from the above explanation, since the pallet truck with a stopper according to the present invention is constructed as described above, it is possible to prevent the movement of the cargo and prevent damage to the cargo.
