Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner member of a frame in an office wagon.

[0002]

2. Description of the Related Art An office wagon is very convenient because it can be moved to the side of a desk or computer equipment with a large number of files and folders mounted thereon, but a conventional wagon is a pair of steel wagons formed of steel pipes. Since a shelf board is erected between the frames, there are the following disadvantages.

In many cases where the frame is formed of a steel pipe, the upper corner of the frame is a right angle. There was a danger of injuries, such as accidentally hitting the wagon. In addition, since two pipes are welded at the time of manufacturing, the trace of welding is unsightly, and the finish of the product varies, which causes defective products. In some cases, the corner members are not formed in a right angle, and the frame is bent. However, since the bending angles do not match and the finish varies, it has been extremely difficult to produce a product of uniform quality.

[0004]

The object of the present invention is to eliminate the risk of the corners of the wagon and to provide a wagon that can be uniformly manufactured.

[0005]

Means for Solving the Problems The two ends of the oblique side (1) having an inverted U-shaped cross section are bent to form fitting portions (2), which are molded with synthetic resin, and nuts are fitted to each fitting portion (2). The fitting recess (3) of (5) is provided. Each end of the upper horizontal portion (6) of the steel frame is fitted into the upper fitting portion (2) of the square member (4) formed as described above, and the nut (5) and the bolt (7) are fitted.
Then, the corner member (4) and the horizontal portion (6) of the frame are fixed. When the upper end of the vertical part (8) of the frame is fitted into the lower fitting part (2) of the corner member (4) and fixed with the nut (5) and the bolt (7), the pair of left and right frame bodies (9) becomes It is formed. After that, a well-known top plate (10), shelf plate (11) and the like are attached between the frames (9), and casters (12) are provided on the legs to complete the wagon.

[0006]

As described above, since the corner member (4) is not a right angle as in the prior art but has a hypotenuse, even if the body is struck, there is no danger. Also, the assembly of the corner member and the frame is simple and does not require skill.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an example of the embodiment will be described. Both ends of an oblique side (1) having an inverted U-shaped cross section are bent inward to form a fitting part (2), and molded with synthetic resin. Fitting part (2)
One side is provided with a recess (3) for inserting a nut (5) to form a square member (4), and the upper horizontal portion (6) of the steel frame body is inserted into the insertion portions (2) on both upper sides of the square member. Each end is fitted and fixed with nuts (5) and bolts (7). Next, the upper end of the vertical portion (8) of the frame is fitted into the lower fitting portion (2) of the corner member, and is fixed with a nut (5) and a bolt (7) to form a pair of right and left frames (9). Form.

A top plate (10), a shelf plate (11) and the like are provided between a pair of frames formed as described above, and a caster (12) is attached to a leg portion. Note that a plurality of reinforcing plates (13) may be provided inside the oblique side (1) of the corner member.

[0009]

[Effects of the Invention] When a wagon is manufactured using the product of the present invention, there is no danger even if the body is accidentally crashed because the pair of frames have no horn-like corners at the upper ends and are inclined sides. . In the case of processing, since there is no bending, there is no room for occurrence of defective products as in the conventional case, and uniform quality can be achieved. Also,
Since there is no welding work and only fixing with bolts, efficient work is possible. Since the square member is molded with a synthetic resin, it is easy to color, so that a color-coded wagon is formed. If the hypotenuse is used as the handle, there are many advantages such as the wagon moving operation can be performed reliably.
