Description

[Detailed explanation of the invention] Industrial field of application This invention is mainly used in large stores, etc., to efficiently transport large quantities of meat, sashimi, and other packaged goods on trays by hand. In addition, it has swivel casters,
The present invention relates to a transport vehicle having a multi-stage substantially horizontal cargo shelf.

BACKGROUND TECHNOLOGY Conventionally, hand-held vehicles equipped with swivel casters and having a multi-tiered substantially horizontal cargo rack are disclosed in, for example, Publication of Utility Model Publication No. 54-17945, Publication of Utility Model Publication No. 58-5659, or Design Registration No. 494285. It is described in and belongs to the public knowledge.

What these transport vehicles have in common is that they are generally made of metal, have a total of four pillars at the four corners, and the required number of shelves (tray mounting frames) are arranged vertically along these pillars. It is arranged horizontally, and articles are placed on a tray having the same shape and size as the cargo shelf, and this tray is placed on the cargo shelf.

Problems that the invention aims to solve In the case of the conventional transport vehicle mentioned above, the tray, which is approximately the same shape and size as the cargo shelf, can only be taken in and out in the longitudinal direction due to the relationship with the supports at the four corners of the transport vehicle; However, there was a problem in that the supports made it difficult to take the tray in and out, making it difficult to handle the tray.

Additionally, conventional transport vehicles are generally made of metal, are therefore heavy, and have problems with rust. For this reason, the manufacturing process required painting and finishing processes after welding and assembling the struts, luggage racks, etc., making it time-consuming and expensive.

In addition, aluminum trays have the problem of rattling and making a lot of noise every time they vibrate on the shelf during transportation.

Therefore, the purpose of this invention was to firstly make the work easier as there is no directionality when loading and unloading trays, and also to make the trays made of synthetic resin without the problem of rust, making it less noisy when transporting goods. An object of the present invention is to provide a hand-push vehicle with an improved and inexpensive structure.

(Means for Solving the Problems) As a means for solving the above problems, the transport vehicle of this invention is equipped with flexible casters and has multiple nearly horizontal loading shelves, as shown in the embodiment in the drawings. (a) First, a total of two pillars 3, one at each diagonal position on the trolley 2 to which the swivel caster 1 is attached, are installed.
3 was established.

(b) Then, a required number of tray mounting frames 4 having a substantially rectangular planar shape with the positions of the pillars 3, 3 as diagonals were attached in the vertical direction along the two pillars 3, 3.

(C) In addition, a tray locking member 5 is attached to the frame members 4a, 4a parallel to the longitudinal direction of the tray mounting frame 4, and trays b placed one by one on the tray mounting frame 4 are attached to the tray locking member 5. 5 to stabilize the placement position.

In addition, the two pillars 3, 3, the framework of the trolley 2, the tray mounting frame 4, and the tray locking member 5, which are the components of the above-mentioned transport vehicle, are each made of synthetic resin or are made of synthetic resin coated steel pipes and the joints are glued together. It was formed by combining.

(Function) Since the tray mounting frame 4 has a simple structure with only two supports 3, 3 in total, one at each diagonal position, the tray 6 has the same shape and size as the tray mounting frame 4. Even if it is, it can be taken in and out freely from either the longitudinal direction or the lateral direction of the tray mounting frame 4, and there is no particular directionality.

Then, the tray 6 placed on the tray mounting frame 4
The movement in the transverse direction is restrained by the tray locking member 5, and the movement in the longitudinal direction is restrained by the diagonally positioned columns 3, 3.
Since it is restrained by the treadmill, unstable shearing motion will never occur.

Furthermore, the number of pillars 3 is reduced to just two, and the structural elements except for the swivel caster 1 are formed by combining synthetic resin pipes and joints, so there is no problem with rust. Moreover, even if the tray 6 is made of aluminum, the noise caused by rattling during transportation is extremely small.
Furthermore, assembly is extremely simple and can be manufactured at low cost since the only work required is gluing the joints and pipes together.

(Example) Next, a preferred example of the illustrated invention will be described.

FIG. 1 shows the overall structure of a transport vehicle according to this invention.

In the figure, reference numeral 1 indicates a swivel caster, and a total of four casters are attached to the lower part of each of the four corners of the truck 2.

As shown in FIG. 2, the trolley 2 is a pipe frame structure having a rectangular planar shape, for example, about 240 mm in length and 740 mm in width. At the diagonal position, support pipes 3 and 3 with a total height of about 1255 mm are erected, and at the remaining diagonal position, auxiliary support pipe 2 with a length of about 150 mm is installed.
a, 2a are erected, and the swivel casters 1, 1 are attached to the lower ends of each. The support pipe 3 and the auxiliary support pipe 2a are connected to T-shaped joints 2b, 2.
b is connected by a vertical connecting pipe 2c, and the vertical connecting pipes 2c, 2c are connected by T-shaped joints 2d, 2d attached at the center of each, and a horizontal connecting pipe 2e, so that the frame of the bogie 2 is rigid. It is configured as.

The support pipe 3, the auxiliary support pipe 2a, and the vertical and horizontal connecting pipes 2c and 2e are resin-coated metal pipes with an outer diameter of approximately φ28, each of which is a thin-walled steel pipe whose outer periphery is coated with AAS resin and whose inner surface is coated with anti-corrosion coating. . On the other hand, the T-shaped joints 2b and 2d are also injection molded products made of AAS resin, and each is firmly adhered by an adhesive for AAS resin in a so-called solid welding manner.

Next, the lowest tray mounting frame 4A has a right-angled three-way joint 4b attached to the upper end of the auxiliary support pipe 2a, and a right-angled three-way joint 4c attached to the support pipe 3 at the same level. The frame material pipe 4a in the longitudinal direction and the width direction between
It is constructed by connecting with 4a'.

Of course, the frame material pipes 4a and 4a' are resin-coated metal pipes coated with the above-mentioned AAS resin.
The directional joints 4b and 4c are injection molded products of AAS resin, and each is adhered with an adhesive for AAS resin.

All of the upper tray mounting frames 4 have the same configuration. That is, in the diagonally positioned support pipes 3, 3,
A right-angled two-way joint 4d for penetrating the strut is installed at a common height position with a pitch of, for example, 150 mm in the vertical direction, and the frame material pipes 4a and 4a' in the longitudinal and transverse directions connected to this are connected to the remaining pair without a strut. The tray mounting frame 4, which has a planar rectangular shape (Fig. 2), is connected to right-angled L-shaped joints 4e, 4e arranged at corner positions, and is supported by supports 3, 3 only at two diagonal positions. It is configured as.

The joints 4d and 4e are injection molded from AAS resin, and are bonded to the frame pipes 4a and 4a' using an ASS adhesive.

In the figure, 5 is a tray locking member attached to the longitudinal frame pipe 4a. As shown in detail in FIG. 3, this has an upward protrusion 5a, and
is attached in a direction parallel to the axis of the frame material pipe 4a. The tray 6 is stabilized so that the raised edges 6a of its peripheral edge are locked to the protrusions 5a so that it does not slide. This tray locking member 5 is also an injection molded product of AAS resin, and is molded into a substantially C-shape that can be fitted into the frame pipe 4a from the lateral direction, and is firmly connected to the frame pipe 4a with adhesive. It is fixed.

Reference numeral 7 in FIG. 1 is a cap fitted onto the upper end of the support pipe 3.

Note that the tray 6 is usually made of aluminum,
It is said to be approximately the same shape and size as the tray mounting frame 4 (Figure 2)
Packed sashimi or meat products 8 from the store are placed on the tray 6.

With the above configuration, the tray 6 carrying the product 8 can be taken in and out of the tray mounting frame 4 of the desired stage from either the longitudinal direction or the lateral direction without any interference with the support pipe 3. can do.

When the tray 6 is placed on the tray mounting frame 4, its sliding movement in the transverse direction is restrained by the tray locking member 5, and its sliding movement in the longitudinal direction is restrained by the support pipes 3 on both sides. (Fig. 2), the stability is good.

(Effects achieved by the invention) As detailed above in conjunction with the embodiments, in the case of the transport vehicle of this invention, there is no directionality in the work of loading and unloading the tray 6 with respect to the tray mounting frame 4. This makes it easy to work even in small stores.
It is very convenient to use.

Since the tray 6 is entirely made of synthetic resin, there is no problem of rust, it is easy to assemble, it is lightweight, and the noise caused by rattling of the tray 6 during transportation is small.

The number of columns 3 has been reduced to just two, and the only assembly required is gluing the pipes and fittings, so it requires less man-hours and can be manufactured at low cost, reducing costs by approximately 30% compared to conventional metal products. .
