A post-pallet trolley 1 (hereinafter also simply referred to as "trolley 1") of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, the post-pallet truck 1 is generally formed in a substantially rectangular shape in plan view, and a plurality of struts 4 are provided at positions facing each other with the pallet table 2 interposed therebetween. Further, the truck 1 has a plurality of casters 6, and these casters 6 are provided with wheel brakes 8 for preventing the truck 1 from moving unexpectedly.

FIG. 2(a) shows a state in which the truck 1 with the wheel brakes 8 applied is stopped on the floor surface 24. FIG. This truck 1 has a plurality of struts 4 and an outer cylindrical body 10 . The outer cylinder 10 is formed in a tubular shape such as a cylindrical shape or a square cylinder shape, and is configured so that the struts 4 provided inside each outer cylinder 10 can move in the vertical direction. there is

FIG. 2(b) shows that another post-pallet truck 26 is stacked on top of the stopped post-pallet truck 1. FIG. In one embodiment, when the upper end 22 of the stanchion 4 of the carriage 1 is overlaid by the bottom foot 30 of another carriage 26, the stanchion 4 moves downward inside the outer casing 10 of the carriage 1. , the bottom foot 14 provided at the lower end 12 of the support 4 is grounded. Thus, the carriages 1 and 26 are stable and do not move unexpectedly even on a slightly inclined surface.

FIG. 3(a) is a perspective view showing the internal structure of the strut 4 when the bottom foot 14 is separated from the floor surface 24, and FIG. 3(b) shows a cross section at that time. Also, FIG. 3(c) is a perspective view showing the internal structure of the strut when the sole foot 14 is on the ground, and FIG. 3(d) shows a cross section at that time.

In the embodiment shown in FIG. 3, one or more coil springs 16 are provided inside the hollow post 4 . In one embodiment, the upper end of the coil spring 16 is fixed to the post 4 using a fixing screw 18 via a fixing member 17, while the lower end of the coil spring 16 is attached to the outer cylinder 10. Its movement is limited by a stop 7 which is fixed and extends into the column 4 so that it cannot move below a position where it abuts.

That is, when a plurality of trucks 1 and 26 are stacked, when the strut 4 of one truck 1 receives a load from the other truck 26 from above, the strut 4 of the lower truck 1 moves downward, and finally , the bottom foot 14 of the support 4 touches the floor surface 24 . The impact at the time of this grounding is relieved by the coil spring 16 in the column 4, and the noise generated at that time is also reduced. In other embodiments of the present invention, instead of the one or more coil springs 16, an oil damper, a synthetic resin rubber body, or the like may be used as the elastic member.

In a further embodiment, the fixing screw 18 that secures the stopper 7 to the barrel 10 passes through an elongated hole or notch 5 formed in the wall of the column 4 and extends through the column 4. The upper end of the elongated hole or notch 5 is formed at a predetermined position so that the bottom surface of the bottom foot 14 does not fall below the lower ends of the casters 6 . In other words, when the post 4 descends and the fixing screw 18 comes into contact with the upper end of the elongated hole or notch 5, the elongated hole or notch is formed so that the post 4 cannot descend further. A positional relationship between the upper end of the notch 5 and the fixing screw 18 is determined.

In another embodiment, when the bottom foot 30 of another carriage 26 is placed on the stanchion 4 of the truck 1, the stanchion 4 moves downward inside the outer casing 10, but the bottom of the stanchion 4 does not move. The bottom surface of the foot 14 may be higher than the lower end of the caster 6 in some cases. In such a case, the carriages 1 and 26 can be stabilized by inserting a pedestal or the like between the floor surface 24 and the bottom feet 14 of the pillars 4 . As shown in FIG. 2 , the upper end 22 of the support 4 is always higher than the top surface of the pallet table 2 before and after the support 4 moves up and down inside the outer cylinder 10 .

As shown in FIGS. 3(a) and 3(b), when the column 4 of the truck 1 is not receiving any force from above and the coil spring 16 in the column 4 is not significantly contracted, the bottom of the column 4 is The bottom surface of the foot 14 is separated from the floor surface 24. - 特許庁Then, another truck 26 is stacked on the truck 1, and when the struts 4 of the lower truck 1 receive the load from the upper truck 26, as shown in FIGS. 3(c) and (d), Inside the outer cylindrical body 10, the strut 4 moves downward (in the direction of arrow A) while contracting the coil spring 16 so as to press it against the stopper 7, and finally the bottom foot 14 of the strut 4 collides with the floor surface 24. . A coil spring 16 fixed to the column 4 mitigates the impact at the time of the collision.

After the carriages 1 and 26 are used, when the upper carriage 26 is removed from the lower carriage 1, the elastic energy stored in the coil springs 16 of the lower carriage 1 is used to extend the coil springs 16 while the struts 4 are moved. is pulled up, the bottom foot 14 of the support 4 is separated from the floor surface 24 again, returning to the state shown in FIGS. 3(a) and 3(b).

FIG. 4 shows two trucks 1, 26 stacked on top of each other. Various items can be placed and stored on the respective pallet stands 2, 32 of the carts 1, 26 shown in FIG.

In another example shown in FIG. 5, pallets 34 are placed on the respective pallet platforms 2, 32 of the stacked carriages 1, 26, respectively, and then the goods are stored on the pallets 34. In some cases.

As described above, in the post pallet truck of the present invention, the elastic member 16 provided on the column 4 functions as a cushioning means for absorbing the impact when the column 4 moves downward and collides with the floor surface 24 . Furthermore, since the elastic member 16 is provided inside the column 4, the appearance of the post-pallet truck of the present invention is good.
