2. Description of the Related Art Hand carts, skit carts, and many other types have been proposed and used as carts used for transporting articles such as containers. However, many of these conventional transport carts have been proposed to be improved with emphasis on loading and unloading of containers, workability at the time of unloading, ease of transport, and stability of container loading. There have been few improvements or improvement proposals focusing on the simplicity of storage of the trolley itself after use, the economy of storage space, or the ease of transportation of the trolley itself. The bogie is usually provided with a handle for carrying and moving, but the most common fixed handle type bogie requires a large space for storing the bogie when the bogie is not used, for example, and the number of bogies is large. In many cases, it is often difficult to secure a storage space.

In order to save this storage space as much as possible, a trolley having a handle that is folded and folded has been proposed or used. However, a trolley of this type is compared with a trolley of a fixed handle type in which a trolley is stacked and stored. Although space can be saved, the strength of the handle is weaker than that of the fixed type, and the workability is not only inferior to that of the fixed type, but also the structure is complicated and the production cost is high. Had.

[0006]

The transport vehicle according to the present invention is characterized in that a concave portion is provided on the loading surface of the truck so that the casters can be fixedly fitted in the transport surface. The wheels of the casters on the loading surface of the
Position corresponding to a pair of casters on the handle fixed end side
The loading state of the loading cart is stabilized by being fixedly fitted in a concave portion provided only in the loading section, so that a plurality of carts can be stably and safely stacked one after another. This allows not only a large number of trolleys to be stacked and stored in a compact manner, but also when many trolleys are required, the stacked trolleys can be freely transferred at once to the required location. can do.

In the present invention , the concave portion formed on the loading surface of the truck to fix the caster of the loaded truck in a fitted state corresponds to a pair of casters whose concave portions are closer to the handle fixed end of the loading surface. only provided in a position.

That is, since the concave portions are provided only at the corresponding positions described above, the wheels of the pair of casters on the side near the handle fixed end of the mounting truck can be moved to the loading truck (the lower stage when stacking). In a state in which the mounting trolley is stably fixed on the container loading surface of the mounted trolley, the mounting trolley is fitted into the horizontal container loading surface of the mounted trolley. The caster wheel is fixed and fixed in a state in which it is inclined toward the handle by the amount of sinking in the recess.

As can be easily understood by referring to FIG. 4, the mounting carriage thus inclined and fixed to the handle side is supported by the mounting carriage in the fitting concave portion, and is mounted on the mounting carriage. The stationary handle is also supported by the fixed handle portion, so that the stationary stability is significantly increased as compared with the case of a horizontal staircase supported and fixed only by the fitting concave portion, and in the case of slight vibration, transfer on an inclined surface, etc. Also, the fixed state does not collapse. Further, since there are two concave portions, there is an advantage that the operation of mounting the truck and fitting the wheels of the casters into the concave portions is easier.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The carrier of the present invention will be described in more detail with reference to specific examples. Figure 1 is a perspective view of a carriage of a conventional manner provided with recesses corresponding to each of the two pairs of casters stacking surface. In the truck of this aspect, when stacking the trucks, first, a pair of trucks on the fixed handle installation side of the trucks to be normally mounted are first placed on the loading surface of the loaded truck, and then the pair of casters are moved on the loading surface. Into the corresponding recess provided on the fixed handle side of the mounted truck, and at the same time, the other pair of casters of the mounted truck are fitted into the corresponding mounted truck recess, and the mounted truck is mounted on the loading surface of the mounted truck. Fix in place. Of course, the mounting cart can be lifted by any means and the two pairs of casters can be simultaneously fitted and fixed in the concave portion of the mounted cart, or the pair of casters on the side opposite to the fixed handle side described above can be fitted first, and then It goes without saying that the casters on the fixed handle side can be fitted.

In the truck of this aspect , the caster guide for communicating between the fixed handle side and the opposite side (rear and front) recesses of the two pairs of caster fitting recesses on the loading surface of the truck. It is preferable to provide a streak-like groove portion, and in a bogie provided with such a groove, first, an arbitrary pair of casters of the mounting bogie is fitted at an appropriate position in the groove along the streak of the mounting groove. Is moved to fit the pair of casters into the corresponding concave portions, so that the two pairs of casters can be easily fitted and fixed in the respective concave portions, and the stacking operation can be easily performed.

FIG. 3 is a perspective view showing a truck having a pair of recesses provided only at positions corresponding to a pair of casters on the handle fixed end side of the loading surface in the present invention.
As described above, in the bogie of this aspect, when the bogies are stacked, the mounted bogie is fixed to the loading surface of the mounted bogie with a slight inclination toward the handle (see FIG. 4). Significantly improved the stationary stability. Also in the truck of this aspect, it is more preferable that a groove for guiding the caster wheels is provided in each of the pair of recesses from the fixed handle side to the opposite side.

It is preferable that at least one of the casters provided on the truck of the present invention is a caster with a stopper. In this case, at the time of stacking, the stopper of the mounted truck is locked to stabilize the truck. It can be set in the state, and further put another truck on the loaded truck,
After the wheels of the respective casters of the truck are fixed in the caster fixing recesses of the truck to be mounted, the stoppers of the casters of the truck are locked, thereby further stabilizing the stacked state.

The shape structure of the caster fixing recess is not particularly limited as long as it is a shape structure in which the wheels of the caster can be properly fixed, but it is convenient for the wheels to be fixedly fitted in the recesses. It is preferable to have a shape and size that are good, for example, a concave shape, a semi-elliptical shape, and an inverted trapezoid trapezoid having substantially the same shape as the wheel. Also, if a small hole for draining water is provided near the bottom of the concave portion, water and the like do not stay in the concave portion, which is convenient for cleaning and washing the bogie, and also wets the casters of the stacked bogies. There is an advantage that there is no such thing.

In the present invention, there is no particular limitation on the material of the supporting plate of the truck constituting the loading surface, as long as it can achieve the loading function of the container of the truck and sufficiently withstand the mounting load at the time of stacking. Any material such as metal, plastic, wood and a combination thereof can be used, but plastic is preferred because it is lightweight and easy to mold, and does not have rust, corrosion and the like. In this case,
Ribs for reinforcing the strength of the support plate may be provided on the back surface (bottom side) of the support plate with respect to the tower surface to reduce the weight of the support plate.

As the casters mounted on the truck of the present invention, those known per se can be used. Each caster is mounted on a support plate so that its wheels can take positions corresponding to the caster fixing recesses. Must be installed. Usually, casters are provided with a pivot between a mounting portion to a support plate or the like and a wheel support portion in consideration of mobility at the time of transport, and a structure in which wheels can freely rotate around the pivot is used, In the present invention, among such casters, those having a structure in which the pivot and the shaft of the wheel are not located on the same vertical line but are slightly shifted are preferably used.
