DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container carrier which is easy to handle.

[0002]

2. Description of the Related Art Conventionally, as a container carrier of this type for simply placing and transporting agricultural containers and the like, a push handle is provided upright at a rear portion of a substantially U-shaped frame.
Rolling wheels are mounted on the left and right sides of the frame, a fork of approximately the same shape as the frame is arranged inside the frame, and the fork is configured to be able to move up and down by an operation lever. Is placed and transported in a vertically moving state.

[0003]

However, in the above-mentioned conventional container carrier, the frame on which the rolling wheels are mounted and the fork on which the container is mounted are separate bodies, and the fork and the lifting mechanism of the fork are placed inside the frame. Since the fork must be provided, the movement of the fork elevating mechanism is restricted, and the fork cannot be lifted above the ground. Therefore, the use of the container carrier is mainly used in a flat place, and it has been difficult to freely use the container carrier in a field having many irregularities.

[0004] Further, the frame disposed outside the fork tends to be large, and a heavy member made of metal is used because the frame or the fork requires a certain strength. Therefore, it was too heavy for women and the elderly to use.

[0005] It is an object of the present invention to provide a container carrier which can solve the above-mentioned problems, has a simple structure, is lightweight, and can increase the amount of elevation of a fork.

[0006]

Therefore, according to the present invention, an approximately U-shape is provided in which an engaging portion is provided at the rear end, a handle is erected, and a container accommodating space is formed inside. A fork and, on the left and right sides of the fork, a base end rotatably connected and disposed so as to straddle the fork, and
A substantially U-shaped operation lever having a hook that is attached to and detachable from the engagement portion at the rear end, and a left and right link mechanism interposed between the operation lever and the fork so as to be vertically swingable. Left and right wheels attached are provided. Therefore, the structure is simplified and the weight can be reduced.
When the operation lever is pulled down with the container positioned in the container storage space, the wheel becomes a fulcrum and the fork itself rises in a sufficient amount, and at the same time, the hook engages with the engaging portion and the fork's floating posture can be maintained. The container can be transported very easily.

According to the present invention, the link mechanism has one end rotatably connected to an upper end of a support member projecting from a side of the fork, and a wheel mounting shaft projecting from the other end. And a second link having one end rotatably connected to a middle portion of the first link and the other end rotatably connected to a middle portion of the operation lever.

An operation lever formed in a substantially U-shape like the fork is pivotally connected to the left and right sides of the fork so as to straddle the fork so as to straddle the fork.

[0010] A hook is rotatably mounted on the folded portion of the operating lever so as to be rotatable around an axis, and an engaging portion for engaging the hook is attached to a rear end of the fork.

A link mechanism interposed between the operation lever and the fork has one end rotatably connected to an upper end of a support member protruding from a side of the fork, and the other end rotatably attached to the wheel. A first link protruding the wheel mounting shaft,
A second link may be configured such that one end is rotatably connected to a middle part of the first link and the other end is rotatably connected to a middle part of the operation lever.

[0012] With this configuration, the fork can be lifted at a height enough to avoid unevenness of the road surface from the grounding position by its own weight with the grounding portion of the wheel as a fulcrum by the operation of pulling down the operating lever, and provided on the operating lever. By engaging the hook with the engaging portion provided on the fork, the container can be easily transported while maintaining the floating attitude of the fork. Therefore, it can be suitably used in a field or the like.

When lowering the fork, the hook is disengaged from the engaging portion by slightly lowering the operating lever.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a container carrier A according to this embodiment.
FIG. 2 is a plan view of the container carrier A, FIG.
4 and FIG. 4 are explanatory views as viewed from the side.

As shown in the figure, the container carrier A according to the present embodiment has side plates 11 and 11 whose front ends are slightly opened outward.
And a rear plate 12 connecting the rear ends of the side plates 11, 11 to each other, to provide a substantially U-shaped fork 1 in which a container accommodation space Q is formed inward, and the side plates 11, 11 and the rear plate On the inner surface of 12, flanges 10, 10 for supporting the lower surface of the container C are continuously provided. Reference numeral 13 denotes a reinforcing plate provided between the side plate 11 and the rear plate 12.

An inverted U-shaped handle 2 protrudes from the left and right ends of the rear plate 12, and an upper opening 30 is formed between the left and right rising portions 20 of the handle 2 so as to be larger than the lower opening 31. An expanded engaging portion 3 is provided.

An operation lever 4 having bases 40, 40 rotatably connected to the front side of the left and right side plates 11, 11 of the fork 1 is attached to the fork 1 so as to be swingable up and down so as to straddle the fork 1. ing. 41 is a lever connection shaft.

The operating lever 4 is formed in a substantially U-shape like the fork 1, and a hook 5 which is detachably attached to the engaging portion 3 is attached to the center of the folded portion forming the rear end. I have.

As shown in FIGS. 3 and 4, the hook 5 has a hook-like tip when viewed from the side, and operates an angle plate having a tread plate 5a so that the foot can be stepped down by foot. The lever 4 is rotatably mounted via a rotation shaft 50, and further has angled stoppers 51, 51 for restricting the rotation range of the hook 5 to a predetermined range in the front-rear direction. Therefore, when the tread plate portion 5a is stepped on, the tread plate portion 5a abuts on the upper end of the stopper 51 and does not rotate any more, and also rotates in the opposite direction at the lower end of the stopper 51. Will be regulated.

Further, left and right link mechanisms 6, 6 are provided between the operation lever 4 and the fork 1, and the left and right wheels 7, 7 are vertically rocked via the link mechanisms 6, 6. It is movably mounted.

That is, the link mechanism 6 has one end rotatably connected to the upper end of a support 14 projecting from the side of the fork 1 and the other end rotatably mounting the wheel 7 on the other end. A first link 61 projecting from the first link 61
A second link 62 has one end rotatably connected to a middle part of the operation lever 61 and the other end rotatably connected to a middle part of the operation lever 4. 61a is a first link connecting shaft protruding from the support 14, and 62a and 62b are second link connecting shafts.

With this configuration, as shown in FIG. 3, in a normal state, the fork 1 is in contact with the ground G together with the wheels 7, 7 due to its own weight, and the operation lever 4 swings downward. In this state, as shown in FIG. 4, the first link 61 pivots downward through the second link 62 by the lowering of the operating lever 4, and the fork 1 is brought into the ground posture with the ground portions of the wheels 7, 7 as fulcrums. Levitate from.

Then, the hook 5 provided on the operation lever 4 is engaged with the engaging portion 3 provided on the fork 1, and the fork 1 holds the floating posture, so that the container C can be easily transported.

On the other hand, when the fork 1 is lowered, the operation lever 4 is slightly pulled down so that the hook 5
, The fork 1 is automatically lowered by its own weight.

In order to raise the fork 1 when the container C is actually loaded and transported, the tread plate portion 5a of the hook 5 provided on the operation lever 4 may be stepped down, but the handle 2 is moved downward. It can be operated more easily by pushing it down.

That is, when the handle 2 is pushed downward in FIG. 3, the wheels 7, 7 try to maintain the state of being in contact with the ground, so that the fork 1 is levitated by the reaction force, and the operation lever is inevitably. The hook 5 is engaged with the engaging portion 3 in the same state as the swinging of the hook 4 downward (see FIG. 4). It is natural that the inclination of the fork 1 when the hook 5 is engaged with the engagement portion 3 is set so that the stacked containers C do not collapse. If the positional relationship between the hook 5 and the engaging portion 3 is determined in this manner, a good pushing-down stroke can be obtained even when the hook 5 and the engaging portion 3 are engaged when the operating lever 4 is pushed down with a foot.

Further, naturally, the container carrier A
Is set such that the diameter of the wheel 7 and the length of the first link 61 are matched so as to match the rising height of the fork 1.

As described above, in the container carrier A according to this embodiment, the wheels 7, 7 are swingable relative to the fork 1, and the fork 1 also avoids unevenness such as a field or a ridge. Therefore, it can be suitably used for transporting the agricultural container C.

In addition, since a frame for mounting the wheels 7, 7 is not required as in the prior art, the weight can be reduced, and the mechanism for raising and lowering the fork 1 has a simple structure. Becomes
