Description

[Detailed description of the invention] [Industrial application field] This invention relates to a hand truck for transportation, and more specifically, the invention relates to a hand truck for transporting goods that require special hygiene precautions, such as food, from one place to another. This relates to improvements to handcarts used for transportation.

[Prior Art] As shown in FIGS. 17 and 18, for example, as shown in FIGS. 17 and 18, a conventional cart of this kind has a reinforcing frame b fixed to the lower surface of a press-formed iron cart body a. A caster c is attached to the lower surface of b, and a plastic or rubber buffer band d is screwed to the outer surface of the trolley body a, or two pressed steel plates are superimposed and a spacer is inserted inside. A buffer belt with a deep groove cross section (horizontal U-shape in cross section) is wrapped around the loaded platform.
Also known is a structure in which the peripheral end of the loading platform is bent into an L shape to form a mounting part, and a buffer band is attached to this mounting part (see Japanese Utility Model Application No. 51-38876).

[Problems to be solved by the invention] However, in the former case, that is, in the case where the reinforcing frame b is fixed to the lower surface of the bogie body a,
After welding the press-formed truck main body a and the reinforcing frame b, the caster c is attached using bolts or the like, which causes problems such as a complicated assembly process and an increase in weight. In addition, even in the latter case, in which two pressed steel plates are superposed, a spacer is interposed between the two pressed steel plates, and after they are superposed, they are fixed with bolts, etc. Similarly, there is a drawback that the assembly requires a large number of man-hours and is a complicated work. Furthermore, since these trolleys are all made of iron, they are susceptible to rust and are unsanitary when transporting food. In addition, since the transport vehicle described in Japanese Utility Model Application Publication No. 51-38876 has an L-shaped mounting portion formed by cutting out the periphery of the loading platform, when attaching the buffer band to this mounting portion, the groove portion of the buffer band is cut out. Installation is troublesome because it must be spread out laterally and attached to the mounting part, or it must be installed by sliding the groove into the mounting part, and there is a risk that the buffer band may be deformed or damaged due to a collision. There was a problem that it took a lot of time to repair. In addition, reinforcing ribs e, e... can be provided on the top surface of these carts at appropriate intervals, but since the spacing is limited, these ribs e, e... can also be used as anti-slip ridges. There is also the problem that it is difficult. In addition, a truck made of a combination of plastic and metal may be considered in order to reduce the weight, but even this type of truck requires complicated assembly work and is not fully satisfactory in terms of hygiene. Therefore, it is currently desired to develop a hand truck for transportation that satisfies these requirements.

This invention was devised in view of the above-mentioned circumstances, and the object is to provide a handcart for transportation that has a lightweight and durable structure and is easy to assemble.

[Means for Solving the Problems] In order to achieve the above object, the handcart for transportation of this invention connects a plurality of aluminum alloy sections to each other by means of fixing means, and A wide-bottomed groove is provided on the side surface of the side, and a cap material body having a wide-bottomed groove of the same shape as the above-mentioned wide-bottomed groove is provided on the other two opposing sides. A cap material consisting of a pair of mounting pieces protruding to sandwich the upper and lower parts is fixed, a buffer band is attached to the wide-bottomed groove to form a loading platform, and a caster is attached to the lower surface of the profile. It is what it is.

In this invention, the fixing means may be any means as long as it connects adjacent sections, but preferably it fastens the abutting portions formed on the connecting sides of adjacent sections. It consists of a bolt and a nut, or a fitting recess formed on one of the connecting side surfaces of adjacent sections, and a fitting convex part formed on the other side to fit into the fitting recess. It is better to consist of

Further, the upper surface of the above-mentioned shape may be of any type as long as it can ensure a flat surface on which the article can be placed, but for example, a group of protrusions or protrusions with a large number of small pitches parallel to each other, or a group of protrusions with a large number of small pitches parallel to each other. It is also possible to form a non-slip part with holes.

Further, the buffer band may be made of any material and shape as long as it is attached to the wide-bottomed groove provided in the profile and the cap material. For example, it may be formed of a synthetic rubber member. It is also possible to provide a shape with a bulge that fits into the wide-bottomed groove.

[Function] According to the handcart for transportation of this invention constructed as described above, a plurality of aluminum alloy sections are connected to each other by fixing means, and two opposing sides of these sections are connected to each other by a fixing means. By sandwiching a pair of mounting pieces and fixing the cap material, by attaching a buffer band to the wide-bottomed groove provided in the shape material and the cap material to form a loading platform, and by attaching the caster to the bottom surface of the shape material, Assembling man-hours can be reduced and assembly work becomes easier. Further, by selecting the dimensions and number of the sections, the shape and dimensions of the loading platform can be set arbitrarily. Furthermore, it is lightweight, easy to handle, and sanitary, allowing safe transportation of foods, medicines, and other items.

Then, the mounting legs 19, 19 of the cap material 18 may be fitted and fixed (see FIG. 15).

On the other hand, the bracket portion 34 of the caster 30 is screwed to a flange portion 64 protruding from the lower end of the vertical portion 63. In this case, as shown in Figure 15,
Bolts 32, 32 are attached to stepped portions 35, 35 provided at the lower portions of the opposing surfaces of the hollow portions 15, 15 of the profile 10.
A mounting plate 33 that is integrally formed with the bracket portion 34 of the caster 30 is fixed to the mounting plate 33 that is fixed with a
may be attached using bolts 37 and nuts 38.

◎ Fourth Embodiment FIG. 16 is a plan view of the main part showing a fourth embodiment of this invention, in which the anti-slip effect of the group of anti-slip protrusions is further improved. In other words, a plurality of (the drawing shows a case of three) sections 10, 10, 10 each having a group of anti-slip protrusions 40 formed of small-pitch protrusions parallel to each other on the loading surface are fixed together as described above. In addition to connecting by means, the section 1
Cap material 1 is attached to the longitudinal side ends of 0, 10, 10.
8 and 18 are attached to form the loading platform 16, and the protrusions of the projection group 40 are formed in a direction perpendicular to the running direction of the truck. Note that a reinforcing channel material 50 is disposed at the center of the lower surface of the loading platform 16 so as to straddle each of the sections 10 , 10 , 10 .

Note that the anti-slip protrusion group 40 is not necessarily limited to being formed of small-pitch protrusions; for example, the protrusion group 40 may be composed of a large number of truncated cone-shaped holes, or it may be formed of a porous It may also have a plate-like structure.

[Effects of the invention] As explained above, according to the handcart for transportation of this invention, which is configured as described above, the following effects can be obtained.
