Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hand truck for transporting products in department stores, warehouses, etc.

[Conventional technology]

There have been various types of handcarts of this type, but even when the handle is folded when not in use, the attachment part of the handle rises above the loading platform and protrudes, allowing it to be loaded onto a vehicle for transporting cargo, etc. It's a hindrance to doing that.

Note that the handcart is often loaded onto a truck or a wagon, and the cargo that is controlled by the wagon is transported using the handcart loaded on the wagon. However, the mounting parts of handles and the like on the loading platform of handcarts were high and could not be stored properly under the floor of the wagon, causing the floor surface to float. Therefore, it is not possible to carry enough luggage.

[The problem that the idea attempts to solve]

The object of the present invention is to provide a handcart that not only has a handle that is foldable but also has a low height at the attachment part of the handle so that it can be stored without taking up much space.

[Means to solve the problem]

The means of the present invention is to fix a pair of mounting frames at both corners of the rear end of the loading platform, rotatably pivot the left and right lower ends of the handle to each mounting frame with pins, and use a support rod bent in a U-shape. The upper rod of the handle is inserted in close proximity to both pivot points of the handle, the lower rod is inserted into the elongated slot formed in the mounting frame, and a shaped stopper member is separately pivoted to each mounting frame with a pin. The lower edges of both sides are provided with a fitting notch into which the lower rod fits in when the handle is in an upright position, and a guide bevel on which the lower rod contacts and slides, and the fitting notch acts in a direction to fit into the lower rod. The spring is wound around the pivot pin of the stopper member, one end of which is locked to the stopper member, and the other end is pressed into contact with the mounting frame.

〔Example〕

In the figure, reference numeral 1 denotes a mounting frame for a handle 20, which is formed into a cross-sectional shape, and its bottom plate 2 is attached to the rear corner of the loading platform 3.
The side plates 4 on both sides of the bottom plate 2 have elongated slots 5 in the center.
, and pin holes 6 and 7 are provided on the left and right sides of the elongated slot 5.

Reference numeral 8 designates a stopper member, which is of cross-sectional type and has side plates 10, 10 on both sides of the upper plate 9, with the front lower part of the side plate 10 serving as a guide bevel 11, and an opening facing downwards adjacent to the side plate 10. A fitting notch 12 is formed, and a pin hole 13 and a shaft hole 24 are drilled in the remaining portion.

The stopper member 8 is fitted into the mounting frame 1 with the upper plate 9 facing upward. Reference numeral 20 indicates a handle, and the end of the handle is inserted into the mounting frame 1 by aligning the pin hole provided on the edge with the pin hole 6 of the mounting frame 1, and the threaded pin 14 is inserted into the pin hole 6. (Fig. 1) Tighten the nut to attach the handle 20 so that it can rotate. Also, the pin hole 13 of the stopper member 8 fitted to the mounting frame 1 and the mounting frame 1
Insert the pin 15 into the pin hole 7, and attach the spring 16 to the shaft of the pin 15 (Fig. 2).
Each edge of the spring 16 is attached to the bottom plate 2 of the mounting frame 1.
and comes into contact with the upper plate 9 of the stopper member.

Reference numeral 17 denotes a U-shaped support rod, the upper rod 17a of which protrudes through an insertion hole bored in the handle 20, into which a threaded nut of the upper rod 17a is screwed. Note that 18 is a contact ring fitted on the upper rod 17a.

Furthermore, the lower rod 17b of the U-shaped support rod 17 is attached to the side plate 4.
The support rod 1 is inserted into the elongated slot 5 provided in the other side plate 4, protrudes from the elongated slot 5 provided in the other side plate 4, and screwed into the threaded portion provided at the edge of the lower rod 17b.
7 is slidable within the elongated slot 5. Reference numeral 19 denotes an arm plate between the upper rod 17a and the lower rod 17b.

Reference numeral 21 denotes a bending release rod, with a horizontal rod portion 22 at the center, and the left and right ends thereof bent to form shaft portions 23, respectively, and the shaft portion 23 is inserted into the shaft hole 2 provided in the stopper member 8.
4 so that it can rotate freely.

[Effect]

When you hold the folded handle 20 on the loading platform 3 and lift up the loading platform 3, the handle 20 will touch the pin 1 attached to the mounting frame 1.
4 as a fulcrum, and at the same time the lower rod 17b slides within the slotted holes 5, 5. This lower rod 17b
guide bevel 11 of the stopper member 8 while sliding.
and presses the beveled edge 11 to move further. Using the pin 15 to which the stopper member 8 is attached as a fulcrum, the lower rod 17b moves by lifting its tip upward and fits into the fitting notch 12 provided in the stopper member 8. Thus support rod 1
7 is fixed, and the handle is raised up so that the baggage can be transported.

When storing next time, rotate the release rod 21 to join the horizontal rod part 22 in the center onto the loading platform 3,
When the shaft portion 23 of the release rod 21 is pushed down by stepping on it from above, the tip of the stopper member 8 lifts up using the pin 15 as a fulcrum against the elastic force of the spring 16, and the lower rod fitted into the fitting notch 12 is lifted. 1
7b is released and moved in the elongated groove 5 toward the attachment part of the handle 20, and at the same time, the handle 20 is tilted in the direction of the arrow shown in FIG. 1, so that the handle 20 lies down on the loading platform.

〔effect〕

According to the present invention, since the mounting frame for attaching the handle protrudes by a height corresponding to the thickness of the handle, it is not bulky and can be stored in a small space of a luggage carrier without getting in the way.
