Description

[Detailed Description of the Invention] The present invention relates to a hanging wheel of a type that has one pair (two wheels) of which the axle and the mounting axis for a door or the like are orthogonal.

Conventionally, this type of hanging wheel has a structure in which the axle and the mounting shaft are perpendicular to each other, and it is difficult to pass two shafts through one body on the same plane, so generally, as shown in Fig. 3, In many cases, the body and the axle that protrudes from side to side are machined as one piece. However, this method has the disadvantage of requiring a large amount of cost to process the body, and in order to prevent the mounting shaft from lifting upward, for example, a groove is machined on the circumference of the mounting shaft, and the body is It was necessary to take measures such as inserting a dowel pin from the outside to prevent it from falling out.

Therefore, the present invention aims to provide an inexpensive hanging wheel by making the processing of the body part easier and eliminating the need for a locking process on the mounting shaft. An example of the invention will be described.

Reference numerals 2 and 2' designate plate-shaped shaft support members, which have through-holes 7 and 7' on the upper side that are larger than the diameter of the axle 6, and on the lower side have through-holes 7 and 7' that are slightly larger than the outer diameter and height of the mounting shaft head 4. rectangular cavities 5, 5', and semicircular recesses 8, 8' with a radius slightly larger than the radius of the mounting shaft 3, extending vertically from the lower ends of the cavities 5, 5' to the lower ends of the main bodies 2, 2'. is provided. In this case, the thickness of the shaft support members 2, 2' below the lower ends of the cavities 5, 5' is:
It must be at least sufficiently larger than the radius of the mounting shaft 3.

Reference numeral 3 denotes a mounting shaft having a shaft head 4 at its upper end, which is used to connect the entire suspension wheel to a door, panel, or other suspended object.

Reference numeral 1 denotes a body section having a cross-sectional shape, the inner dimension of which is slightly larger than the outer dimension of the shaft support members 2 and 2' stacked together. Also, the left and right side walls 1
2 and 12' are provided with axle holes 9 and 9' having a slightly larger diameter than the axle 6 on the same center line.

Now, when assembling the hanging wheel of the present invention, follow the steps below.

First, attach the mounting shaft head 4 in the opposing cavities 5 and 5',
The shaft support members 2 and 2' are overlapped so that the mounting shaft 3 is held between the semicircular recesses 8 and 8'. At this time, a convex portion 13 is provided on one side of the opposing inner wall surfaces of the shaft support members 2, 2', and a concave portion 14 is provided on the other side, and by fitting and overlapping the two, the fitting is ensured. You can also.

Next, the upper parts of the stacked shaft support members 2 and 2' are fitted into the opening of the body part 1 from below, and the axle hole 9,
9' and through holes 7, 7'.

The axle 6 is rotatably inserted into the series of holes 9, 9' and 7, 7', and finally the wheels 10, 10' are inserted into the axle 6.
Attach to both ends. The axle 6 is inserted into the holes 9, 9', 7,
7', and the wheels 10,
It goes without saying that 10' can also be rotatably pivoted.

In this way, the hanging wheel according to the present invention is made up of a combination of parts that are easy to process, making it possible to provide an inexpensive hanging wheel.
