A caster is attached to the front and rear portions of the lower surface of the base plate 2, and a hand handle 30 made of a metal pipe is provided at the rear portion of the base plate 2 so as to be able to be tilted to constitute a hand cart. Further, the reinforcing metal pipe 33 is fitted into both end portions of the hand handle 30 and the fitted portion is pressed to form the flat portion 40, and the flat portion 40 rotates to the rear portion of the base plate 2. It is pivotally supported and attached. [Selection] Figure 5

Description

  The present invention relates to a structure for attaching a hand handle that can be raised and lowered in a hand cart.

  Hand carts are widely used for conveying goods in factories and warehouses, and in home delivery and moving work. As this kind of hand cart, the hand handle can be tilted and stored on the base plate or the lower side of the base plate when not in use, it is compact and easy to carry, and the cart has a large storage space. There is a type that can be done without taking.

  Both ends of the handwheel handle of the carriage are attached to the rear part of the base plate so as to be rotatably supported. Usually, the handwheel handle is a metal round pipe, and the shaft attachment surface to the attachment plate is curved. Therefore, it is difficult to stably fix the shaft support, and there is a problem in that the rotation at that portion is not smoothly performed. Conventionally, in order to solve this problem, a mounting bracket is separately provided at the mounting location. However, in this configuration, a separate member is required and the assembling work is troublesome. On the other hand, when the hand handle is placed on the base plate or the lower side of the base plate when not in use, there is a problem that the end of the round pipe is exposed rearward and the appearance is poor.

  The present invention has been made in view of the above points, and an object of the present invention is to make it possible to easily and stably attach the shaft support of the hand handle and to smoothly rotate the hand handle.

  In this device, casters are attached to the front and rear portions of the lower surface of the base plate, and a hand cart made of a metal pipe is provided at the rear of the base plate so that it can be tilted. The reinforcing metal pipe is internally fitted, and a flat part is formed by pressing the fitted part, and the flat part is rotatably supported and attached to the rear part of the base plate. It was.

  According to the above configuration, the flat structure of the both end portions of the hand handle is attached so as to be rotatable in a state along the attachment surface, that is, in a surface contact state, so that the attachment structure is stabilized and the rotation is also possible. The operation is also smooth. Since the flat portion is formed in a state where the reinforcing pipe is fitted in the metal pipe, the strength is sufficiently maintained. Further, since the circular opening is not visible at the end of the push handle in a non-use state in which the hand handle is stored horizontally, the appearance is good, and since there is no end of the round pipe there is easy handling.

  The hand cart of this invention is applied to both the hand handle that can be raised and lowered and that is stored on the base plate or the lower side of the base plate when not in use.

  According to this device, the shaft support of the hand handle can be easily and stably attached, the rotation thereof can be smoothly performed, and the attachment portion can maintain sufficient strength.

Preferred embodiment

  1 is a side view of the hand cart of the present invention, FIG. 2 is a plan view thereof, and FIG. 3 is a rear view thereof. The handcart 1 has the casters 4 attached in the vicinity of the four corners of the lower surface of the plastic base plate 2 having a rectangular shape (90 × 60 cm) in plan view, and the hand handle 30 made of a metal pipe is provided at the rear of the base plate 2 in the direction of the arrow. The hand handle 30 is tilted backward and rotated when not in use, and is positioned at the lower side of the base plate 2 as shown in FIG.

  Reference numeral 32 denotes an attachment plate on which the end portions 31 of the hand handle 30 are rotatably supported, and are fixedly attached to the lower surface of the rear portion of the base plate 2. Reference numeral 34 denotes a locking rod, and both ends are attached to a convex portion 36 projecting from the inner surface of the mounting plate 32 via respective coil springs 35, and each end portion 37 is elastic to each locking concave portion 39 of each mounting plate 32. The hand handle 30 is maintained in the state of use (FIG. 1) and non-use (FIG. 4).

  With reference to FIGS. 5 and 6, the attachment structure of the end 31 of the hand handle 30 to the attachment plate 32 will be described. A reinforcing pipe 33 having a length of about 20 cm is fitted into the end of a metal round pipe (diameter approximately 3 cm) constituting the end 31 of the push handle 30, and most of the fitted part is on one side. (In the direction of the arrow), the flat portion 40 is formed. The flat portion 40 is disposed along the surface of the mounting plate 32 and is rotatably attached by the pivot pin 41.

  As described above, the flat portion 40 is attached so as to be rotatable in a state along the surface of the attachment plate 32, that is, in a state of surface contact, so that the attachment is made stable and the turning operation is also made smooth. The Since the flat portion 40 is formed with the reinforcing pipe 33 fitted therein, the strength is sufficiently maintained. Further, when the hand handle 30 is not in use (FIG. 4), the circular opening of the end portion 31 is not visible, so that the appearance is good, and since there is no end of the round pipe there is easy handling.
