[Industrial applications]

 The present invention relates to a carriage for carrying articles such as containers. More specifically, the present invention relates to a trolley for transporting articles such as containers, which has excellent storability of the trolley itself and can be easily stacked and stored in a stable state.

[0002]

[Prior art]

 Conventionally, many types of carts, such as hand trucks and skit carts, have been proposed and used as trolleys for transporting articles such as containers. However, many of these conventional trolleys have been improved with emphasis on loading and unloading of containers and other work items, workability during transportation, and loading stability of loads. However, there were few improvements and proposals focusing on ease of storage of the dolly itself after use of the dolly, economy of storage space, and ease of transferring a large number of dollies themselves at one time. A trolley is usually provided with a handle for transporting and moving, but the most common fixed handle type trolley requires a large space for storing the trolley, for example, when the trolley is not in use. When there are a large number of the above, it often happens that it is difficult to secure the storage or the storage place.

In order to save the storage space as much as possible, a trolley with a handle that is folded and folded has been proposed or used, but a trolley of this system is stored by stacking the trolleys as compared with a trolley of a fixed handle type. Although space can be saved, the strength of the handle is weaker than that of the fixed type, workability is not only inferior to that of the fixed type, the structure is complicated, and the manufacturing cost is higher by that amount. There are many inconveniences.

To be done.

The carrier truck of the present invention is formed with a recess on the upper surface of the opposite end of the handle mounting portion of the carriage, while the recess is formed on the lower surface of the handle mounting portion at a position spaced from the handle mounting portion. The feature is that there is a convex part that can be engaged with, so that when stacking transport vehicles, it is possible to easily and easily stack the carts to be mounted on the loaded carts. It is what That is, first, a pair of casters provided on the opposite side of the handle mounting portion of the trolley to be mounted is lifted in a mode in which the fixed handle is a force point with the other pair of casters on the handle mounting portion side as fulcrums, and this is mounted. Place it on the container loading surface near the opposite end of the trolley handle attachment end.

Next, with the to-be-mounted vehicle fixed, the to-be-mounted vehicle is moved to the handle installation side of the to-be-mounted vehicle, and the convex portion provided on the lower surface of the loading surface of the to-be-mounted vehicle and the loading surface of the to-be-mounted vehicle The handle side of the upper surface is engaged with the recess provided near the end on the opposite side. When the concave and convex portions are engaged with each other, the handle of the loading carriage is used as a force point, and the loading carriage is lifted by the lever principle with the engaging portion as a fulcrum to mount the loading carriage on the loading surface of the loaded carriage.

In order to stack the trolleys in three or more stages, the third-stage trolley may be placed on the inclined loading surface of the trolley in which the uneven portions are engaged, or first, It is also possible to use a two-tiered trolley as the loading trolley, and a new trolley as the loaded trolley, and to mount the two-tiered trolley on top of this. In any case, the multi-stage stacking procedure is not limited to these and is arbitrary.

In the trolley of the present invention, the concave portion provided on the upper surface of the end opposite to the handle mounting portion of the loading surface is further provided with a small raised portion on the bottom surface of the concave portion. It is preferable in that the lever action at the time functions efficiently and surely. That is, the mounting operation can be reliably performed with the small protrusion as the center of action of the lever fulcrum, and troubles due to displacement of the fulcrum, slipping, etc. can be prevented.

Further, in the trolley of the present invention, in order to support the stability of the stacked state after the trolley is mounted on the trolley, at least one pair of caster fitting recesses is provided at the portion corresponding to the caster stationary position on the loading surface of the trolley. Is preferably provided, whereby the caster wheels of the mounting carriage can be fitted into the recesses of the mounted carriage, respectively, and the stationary state of the carriage can be maintained in a more stable state. The operational features of the carrier truck of the present invention are as described above, and a specific embodiment of the present invention will be described in more detail below with reference to the drawings.

【Example】

 FIG. 1 is a side view showing an embodiment of a carrier truck provided with an uneven portion according to the present invention. FIG. 2 is a side view conceptually showing a state in which the carts of the embodiment shown in FIG. 1 are mounted in a stack. In the cart of FIG. 1, a small protrusion 7 is provided on the bottom surface of the concave portion 6 provided on the upper surface of the loading surface of the truck opposite to the handle installation end. In the trolley of FIG. 1, as already described above, first, the pair of casters 4 of the trolley to be mounted is placed on the loading surface 1 of the trolley to be loaded, and then the trolley to be loaded is loaded with the trolley to be loaded. The protrusion 5 of the mounting carriage and the recess 6 of the mounted carriage are engaged with each other by moving them to the handle installation side of the mounting carriage. After engaging the concavo-convex portion, the small carriage 7 of the concave portion is used as a lever fulcrum to lift the mounting carriage and mount the mounting carriage on the mounting surface 1 of the mounted carriage.

In the present invention, the small protrusion 7 provided on the bottom surface of the concave portion 6 may be located near the center of the bottom surface of the concave portion, but in view of the function as a fulcrum, it is slightly closer to the handle fixing end side than the central portion. It is preferable to install them in close proximity. As a result, the convex portion of the mounted carriage is first fitted into a portion of the concave portion of the mounted vehicle that is closer to the opposite end than the handle fixed end side (the concave portion on the front side of the small protrusion), and then the small protruding portion tip end. Place the mounted dolly on the loading surface of the loaded dolly using the lever principle, with the handle of the dolly as the contact fulcrum and the handle of the dolly as the point of contact.

FIG. 3 is a perspective view showing an example of a dolly in which a concave portion into which a wheel of a caster of a loading dolly is fitted is provided on a loading surface of a carrier dolly provided with an uneven portion of the present invention. In FIG. 3, four recesses are provided at positions corresponding to two pairs of casters, but a configuration in which two recesses are provided corresponding to any pair of casters is also included in the present invention. Needless to say. In the dolly provided with the caster fitting stationary recess, the stability of the mounted dolly after stacking is good, and the stacking stability is remarkably improved. Further, if the guide groove 9 for guiding the mounted caster to the recess is provided in the caster fitting stationary recess described above, the caster can be fitted easily, which is convenient for mounting the dolly.

It is preferable that at least one caster provided in the truck of the present invention is a caster with a stopper, and in this case, when the stacking is performed, the stopper of the loaded truck is locked to stabilize the truck. It can be placed in a fixed state and the work of mounting the trolley can be performed safely and easily. Also, by locking the casters of the mounted dolly, the mounted dolly can be placed on the loading surface of the mounted dolly in a stable state, and stacking stability is increased.

In the present invention, the material of the supporting plate of the trolley constituting the loading surface is not particularly limited as long as it can achieve the container loading function of the trolley and can withstand the loading load at the time of stacking, metal, Although any material such as plastic, wood and a combination thereof can be used, it is preferable to use plastic because it is lightweight and easy to mold and has no rust or corrosion. In this case, ribs for reinforcing the strength of the supporting plate can be installed on the back surface (bottom surface side) of the stacking supporting plate with respect to the surface of the stacking tower to reduce the weight of the supporting plate.
