Abstract

PURPOSE: To obtain an excellent mobility even on a field with soft base by installing an extended member extended upward advancably/retreatably in front/rear direction on the front/rear ends of a main body and arranging two or more fixed wheels in a row in front/rear direction on the side surfaces of respective axle support members installed on the right/left sides of blue main body lower part. CONSTITUTION: A truck main body 1 is composed of a side rod 1 a consisting of a pipe made of aluminum alloy opened in right/left and front/rear directions and connection plates 1b, 1c for connecting them and its upper surface is formed in a plane. The tip end engagingly locking member 2 and the handle member 3 of the pipe made of aluminum alloy extended upward slightly upto the height of man's waist are installed advancably/retreatably and attachably/detachably on the front/rear ends of time main body. It is constituted so that an auxiliary rod 1d can be fixed along the connection plate 1b and the tip of a side engagingly locking member 6 of a rod made of aluminum alloy extended upward can be inserted in the openings of this both ends. Two wheel support members 8, 8 are installed in a line in the main body width direction on the connection plates 1b, 1b and fixed rubber wheels 9, 9 whose direction is fixed in the front/rear direction are installed on this one side surface side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carriage, and more particularly to a carriage that can be suitably used in a greenhouse or the like.

[0002]

2. Description of the Related Art Various garden crops are produced in a greenhouse. Due to the limited area within such a greenhouse, the ridges for planting crops are usually made as narrow as possible. On the other hand, the work such as planting and harvesting in the vinyl house is carried out between the ridges, and the seedlings to be planted and their tools and boxes for harvesting are also placed on an ordinary trolley to form the ridges and ridges. Transported through the space between. However, as mentioned above, the space between the ridges is narrow, so there are some that cannot be passed by conventional trucks and unicycles.
Also, unicycle carts and carts with small wheels may even get stuck in the field of soft ground, where the wheels may get stuck.

[0003]

DISCLOSURE OF THE INVENTION As a result of studies for solving such a problem, the present invention has developed a trolley made of an aluminum alloy which can be easily moved even in a narrow ridge, and is robust, light and easy to work. .

That is, according to the present invention, the carriage is mounted on the front end and the rear end of the main body so that extension members extending upward can be moved back and forth in the front-rear direction, and the side surfaces of the wheel support members attached to the left and right of the lower part of the main body. In addition, two or more fixed wheels are arranged in a row in the front-rear direction. In this trolley, the extended height of the extension member at the rear end is set to a height at which a person can push and pull the trolley, and the height of the extension member at the front end is set to load and unload the luggage from the trolley. It is effective to set the height so as not to interfere with the above, and it is also effective to make the left and right wheel support members replaceable and / or reversible back and forth. Further, it is also preferable to attach laterally extending laterally extending locking members to the left and right sides of the upper part of the main body so that the lateral locking members can move back and forth in the left and right directions.

[0005]

Embodiments of the present invention will now be described with reference to the drawings.
As shown in FIGS. 1 and 2, the trolley body (1) is composed of a side rod (1a) made of an aluminum alloy pipe that opens in the left and right front and rear directions, and connecting plates (1b) (1c) that connect these to each other. It is formed in a plane.

As shown in FIG. 3, a front end locking member (2) made of an aluminum alloy pipe extending slightly upward is attached to the front end of the main body so as to be capable of advancing and retracting and being detachable, and the rear end thereof is almost upward. As shown in FIG. 3, the handle member (3) made of an aluminum alloy pipe extending to the level of a person's waist is provided.
It was attached so that it can be moved back and forth and detached. That is, referring to FIG. 3, a thumbscrew (4) is provided on the lower surface of the front and rear ends of the side rod (1a), and an aluminum alloy round bar () is attached to the attachment ends of the tip locking member (2) and the handle member (3). 5) is projected and fixed, the round bar (5) is inserted from the tip end opening of the side rod (1a) to an arbitrary depth, and fixed with the thumbscrew (4).

Further, an auxiliary rod (1d) is fixed along the connecting plate (1b) of the main body (1), and is made of an aluminum alloy that extends upward as shown in FIG. 4 at the openings of both ends of the auxiliary rod (1d). The tip of the side locking member (6) of the round bar is configured to be insertable. Then, a thumbscrew (4) is provided at the opening of the auxiliary rod (1d) so that the locking member (6) can be fixed at an arbitrary depth in the auxiliary rod (1d).

Further, the connecting plates (1b) (1b) are provided with elongated holes (7) -in the width direction of the main body, and two wheel supporting members (8) and (8) are respectively attached to the lower portion of the main body by bolts. And installed side by side in the width direction of the main body. The wheel supporting member (8) is formed in a substantially U shape by bending an aluminum alloy square pipe or by assembling it by welding. Fixed rubber wheels (9) and (9) whose direction is fixed in the front-rear direction are attached to one side surface of the wheel support member (8). Since the fixed rubber wheel (9) and the wheel supporting member (8) can change the position in the width direction in this way, the stability of the trolley can be increased by increasing the width between the left and right wheels as shown in FIG. . On the other hand, as shown in FIG. 6, if the left and right wheel support members (8) and (8) are replaced with each other, or the left and right wheel support members (8) and (8) are reversed front and back, the width between the wheels can be made smaller. , It can easily enter even narrow ridges.

According to the carrier truck of the present invention as described above,
When moving multiple pallets containing seedlings of crops on the trolley body or placing a box for picking up,
Since these pallets and boxes are surrounded by the front end locking member (2), the handle member (3) and the side locking members (6) and (6), they are stable without any fear of falling. Furthermore, since it is equipped with four or more wheels, it is stable and can be easily moved even in a weak field. Further, since these wheels have the structure as described above, they are suitable for linearly moving in a relatively narrow ridge in a greenhouse or a field.

Further, since only the handle member (3) is extended to the upper high position, it is easy to load and unload objects from the upper surface of the trolley in the other three directions. Depending on the working condition, the front end and the rear end of the main body may be extension members having the same height. Further, as shown in FIG. 7, the tip locking member (2),
Larger loads can be carried by pulling the handle member (3) and the side locking members (6) and (6) out of the pipes and fixing them to an appropriate length with thumbscrews (4).

[0011]

As described above, according to the present invention, it is possible to provide a carrier truck which is excellent in mobility in a greenhouse and particularly in a narrow field and is lightweight and can be used for various purposes.
