Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed plate for a hand guided vehicle which has a plurality of wheels mounted on the bottom surface and handles attached to all four ends and is used for a hand guided vehicle.

[0002]

2. Description of the Related Art Conventionally, in a hand guided vehicle, two directional fixed wheels (fixed casters) are located rearward (side closer to the user) and two directional wheels (universal casters) are located forward (side farther from the user). It was limited to the hand guided vehicles (vehicles that could move forward) attached to each. In such a hand guided vehicle, it was possible to change from the forward movable vehicle to the hand movable vehicle only by changing the mounting position of the handle.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide mounting holes for directional fixed wheels and directional wheels having different mounting hole intervals and arrangements at all four corners of a bed plate for a hand guided vehicle. It is possible to attach direction-fixed wheels to all the wheels or directional wheels to all four wheels. Further, the wheels can be exchanged from the direction-fixed wheels to the direction-free wheels or vice versa, and the functionality is greatly improved. Furthermore, even by the user, the wheels can be exchanged so that the wheels can be exchanged from the fixed-direction wheels to the directional wheels or vice versa, or the operation can be performed with low human power according to the weight of the article to be conveyed. is there.

[0004]

In order to solve the above-mentioned problems, as a result of intensive studies, the present invention has found that at least one wheel is mounted on a carrier bed plate for a hand guided vehicle in which a plurality of wheels can be removably mounted on the bottom surface. A loading platform for a hand guided vehicle, which has a mounting hole for mounting multiple types of wheels, has been adopted.

Therefore, since it is possible to attach a plurality of types of wheels to the wheel attachment site, it is not necessary to produce a plurality of types of carrier plates for hand guided vehicles having different attachment holes. In addition, the user can also replace the wheel with another type of wheel according to the application, or replace the wheel so that it can be operated with low human power according to the weight of the article to be conveyed.

Further, it is possible to provide one or a plurality of common holes common to a plurality of types of wheels in the mounting holes.

An independent mounting hole may be provided for each mounting hole of different types of wheels, but the mounting hole may be a common hole depending on the arrangement of the mounting holes on the wheel side. The number of mounting holes can be reduced, resulting in improved production efficiency.

A carrier plate for a hand guided vehicle according to claim 2, wherein the direction-fixed wheel and the direction-controllable wheel can be mounted, and the direction-control wheel mounting hole is arranged inside the direction-fixed wheel mounting hole. You can also do it.

As described above, the direction-controllable wheels are sometimes attached so that the traveling direction of the hand-guided vehicle can be easily changed. In the directional wheel, the wheel rotates freely in a horizontal plane, and therefore the wheel may protrude and come into contact with a wall or the like. Therefore, by disposing the directional wheel mounting hole inside the directional fixed wheel mounting hole, it is possible to prevent the wheel from protruding when the traveling direction is changed.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic bottom view showing an arrangement of mounting holes of a bed plate for a hand guided vehicle according to the present invention. In the carrier plate 1 for a hand guided vehicle, the wheels are usually attached to the four corners. That is, in FIG. 1, it is attached to the attachment site 2 surrounded by a circle.

As described above, even when the wheels are attached to the attachment portions 2 at the four corners, the wheels to be attached are not always the same type. For example, directional wheels on the front wheels,
Directional fixed wheels may be attached to the rear wheels, respectively, or directional wheels may be attached to all four wheels. Therefore, it is necessary to attach different wheels to the same attachment site 2.

FIG. 2 is a schematic perspective view of a wheel used in a hand guided vehicle, in which (a) is a fixed direction wheel and (b) is a directional wheel. Usually, the mounting holes 3a of the direction-fixed wheel 3 are arranged in a substantially rectangular shape, and the mounting holes 4a of the directional wheel 4 are arranged in a substantially square shape. Therefore, the mounting holes of the two are different, and it is necessary to arrange the mounting holes corresponding to each.

FIG. 3 is an enlarged view of an essential part including the upper left mounting portion 2 in FIG. In FIG. 3A, a mounting hole 11 is a mounting hole for the direction-fixed wheel 3, and a mounting hole 12 is a mounting hole for the direction-controllable wheel 4, which is formed in the bottom surface of the bed plate for the hand guided vehicle. For convenience of description, the mounting hole 11 is connected by a virtual line 21 and the mounting hole 12 is connected by a virtual line 22.

Since the directionally fixed wheel 3 has a fixed rotating shaft and cannot rotate in a horizontal plane, it is mounted so that the hand guided vehicle can move straight. That is, the imaginary line 21 forms a rectangle, and each piece of the rectangle is the outer edge 1 of the cart bed 1 for a cart.
It is attached so as to be parallel to a and 1b.

On the other hand, since the directional wheel 4 is rotatable in the horizontal plane, the arrangement of the mounting holes 12 is not particularly limited, but is preferably inside the mounting holes 11. That is, the mounting hole 12 may be located inside the sides 21a and 21b of the mounting hole 11 near the outer edges 1a, 1b of the imaginary line 21 (on the side opposite to the outer edges 1a, 1b).
It is less likely that the baggage plate 1 for a hand guided vehicle will protrude from the outer edges 1a, 1b and come into contact with a wall or the like.

FIG. 3 (b) shows an example in which one common hole is provided for both the fixed direction wheel 3 and the directional wheel 4. In the figure, the common hole 13 is located at the lower left, and is also the mounting hole 11 and the mounting hole 12. By providing the common hole 13, the drilling process can be partially omitted, and the productivity is improved.

FIG. 3C shows an example in which two common holes are provided. Since there is a degree of freedom in attaching the directional wheel 4,
The virtual line 22 can be attached so as to rotate by about 45 degrees so that two common holes are formed.

Of course, also in FIGS. 3B and 3C, as described above, the direction-fixed wheel 3 is attached so that the hand guided vehicle can move straight. Further, in order to prevent the wheel from protruding, the mounting hole 12 is formed by the imaginary line 21a,
21b is preferably provided on the inner side (on the side opposite to the outer edges 1a, 1b). Further, the mounting holes 11 and 12 can be similarly provided for the other three wheel mounting portions.

[0019]

As described above, according to the carrier bed plate for a hand guided vehicle of the present invention, different types of wheels can be used depending on the application.
It can be attached, improving productivity and user convenience.
