Description

[Detailed Description of the Invention] The present invention relates to a transportation trolley whose length can be made variable depending on the length of the transported article.

Conventionally, a transportation trolley on which an article is placed and transported to a destination location is generally provided with a plurality of support members on the underside of the article loading table, and rotatably mounted wheels on the lower end of each of the support members. It has a built-in structure. For this reason, once the transportation trolley is manufactured,
It is difficult to change the size of the article mounting table of the transportation trolley, and when the article to be conveyed is a long article, there is a problem that the article becomes unstable. In addition, there is a transportation trolley with a longer article mounting table in order to transport long articles, but this transportation trolley has the disadvantage that the trolley itself becomes large and requires a large storage area.

The present invention was devised to solve the above-mentioned problems, and its purpose is to provide a transportation trolley whose length can be varied depending on the length of the transported article.

The above-mentioned object of the present invention is to provide a trolley including a plurality of support members provided on the lower surface of the article placement table and rotatably provided wheels at the lower end of each of the support members, on both sides of the article placement table of the cart. A cylindrical member in which a slit is formed in the longitudinal direction and a plurality of engagement grooves are formed in a direction perpendicular to the slit is fixed to the surface of the cylindrical member. A transportation trolley characterized in that a plurality of trolleys can be connected by movably inserting a connecting member on which a mating member is formed and locking the engaging member in an engaging groove of a cylindrical member. achieved by.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a perspective view of a transportation trolley according to the present invention, and FIG. 2 shows a perspective view for explaining the state of connection between the cylindrical member and the connecting member used in the transportation trolley of the invention. be. In FIGS. 1 and 2, reference numeral 1 denotes a transport trolley according to the present invention, and this transport trolley consists of two trolleys 2 and 3. These carts 2 and 3 have article mounting tables 4 and 4a,
Four support members 5, 5a, 5b, 5c are provided on the lower surface of the article mounting tables 4, 4a, and four support members 5, 5a, 5b, 5c are rotatably provided at the lower ends of the support members 5, 5a, 5b, 5c. two wheels 6, 6a, 6b, 6
It consists of c. Cylindrical members 7, 7a are fixed to both sides of the article mounting tables of the carts 2, 3, and slits 8, 8a are formed in the longitudinal direction of the cylindrical members 7, 7a. A plurality of engagement grooves 9, 9a are formed in the direction perpendicular to the engagement grooves 8, 8a. Furthermore, a connecting member 10 is movably installed inside the cylindrical members 7, 7a of the carts 2, 3. Engagement members 11, 11a are formed near both ends of the connection member 10, and extend in a direction perpendicular to the axial direction of the connection member 10. It is locked into the engagement grooves 9, 9a.
Then, the engagement grooves 9, 9a of the engagement members 11, 11a
By changing the position at which the carriages 2 and 3 are locked, the carriages 2 and 3 can be moved closer or further apart.

In the transportation trolley configured as above,
When conveying an article (not shown) over a long distance, first, the connecting member 10 is moved inside the cylindrical members 7, 7a, and one of the engaging members 11, 11a is moved inside the cylindrical member 7. At the same time, the other engaging member 11a is engaged with the engaging groove 9a of the cylindrical member 7a, that is, the third engaging groove 9 from the left of the cylindrical member 7a. By locking in the matching groove 9a, the length of the transportation trolley 1 becomes the longest, and long articles can be transported stably. Also, when transporting short items (not shown), as opposed to transporting long items,
The connecting member 10 is moved inside the cylindrical members 7, 7a, and one of the engaging members 11, 11a is inserted into the engaging groove 9 of the cylindrical member 7, that is, the engaging groove at the left end of the cylindrical member 7. 9, and the other engaging member 11a is inserted into the engaging groove 9a of the cylindrical member 7a,
That is, by locking into the engagement groove 9a at the right end of the cylindrical member 7a, the length of the transport trolley 1 is shortened, making it easier to transport short articles. When transporting a smaller article (not shown), the small article can be easily transported by removing the connecting member 10 from the cylindrical members 7, 7a.

As explained above, in the transportation cart according to the present invention, a slit is formed in the longitudinal direction on both sides of the article mounting table of the cart, and a plurality of engagement grooves are formed in a direction perpendicular to the slit. A cylindrical member is fixed, and a connecting member having an engaging member extending perpendicular to the axial direction is movably inserted into the cylindrical member, so that a plurality of carts can be connected. , the length of the trolley can be freely changed according to the length of the transported article, and the article mounting table has the length suitable for the purpose of use. It has the effect of being able to be transported in a stable manner.
