Description

[Detailed description of the invention] (a) Purpose of the invention The present invention relates to a device for stopping the rotation of parts of a chandelier.

Traditionally, chandeliers have been used in places such as gathering places, parties, etc. to take advantage of the original luxury and splendor of the chandelier, rather than general home use.
It is often used in banquet halls, halls, etc., and in these cases, the rotating parts of the chandelier are used at the same time to make use of the atmosphere of the gathering place and the decorative effect other than the original lighting of the chandelier. (decorative reflector), which is used to reflect the light of the chandelier and enhance its decorative effect in the room, and the axis passing through the center of this rotating glass part is Generally, cylindrical shafts were used, but on the other hand, when stopping the movement of parts, with a cylindrical shaft, the shaft and the pipe outside it slide easily, so it is difficult to keep it stationary. It is designed to prevent parts from rotating and ensure that they remain stationary when the parts need to stand still.

(b) Structure of the invention Examples of the invention will be described below based on the drawings.

FIG. 1 shows a perspective view of the entire embodiment of the present invention, and as shown in FIGS. 1 and 3, the central shaft 1 is formed into a hexagonal prism. This shaft 1 is covered with cylindrical pipes 2 at regular intervals, that is, the shaft 1 is inserted through the pipe 2, and a part 3 is attached below the pipe 2. The method of attachment is as follows: First, the pipe 2 is provided with a screw hole 4, as shown in FIG. Next part 3
has a circular through hole 5 in the center as shown in Figure 3.
is provided, and a shaft 1 forming a hexagonal prism is provided in the through hole 5.
The pipe 2 and part 3 are installed on the shaft 1 in such a way that the pipe 2 and the part 3 are arranged vertically without any gaps, and the pipe 2 is fixed to the shaft 1 with screws as described above. If you let me,
Even if the part 3 is simply inserted into the shaft 1 as described above, the pipe 2 below the part 3 will place the part 3, and the position of the part 3 will necessarily be fixed. Part 3 and pipe 2
This makes it possible to arrange several stages up and down as necessary, and if the length of the pipes 2 is kept the same, then
Naturally, the parts 3 are arranged at equal intervals.

With the above configuration, the shaft 1 forming a hexagonal prism is simply screwed to the pipe on the outside thereof, and the two are extremely difficult to slide, thereby preventing the shaft 1 from rotating. The reason for this is that if the shaft is cylindrical, it will be the same shape as the pipe and will slide easily, while for example, if the shaft is octagonal or a larger polygon, it will approach a circle and the shaft and pipe will slide just like a circle. In addition, the contact effect of a quadrilateral is weak as only four of its apex corners touch the inner circumference of the pipe, and based on these reasons, the axis 1 is made into a hexagon and the inside of the pipe 2 is It was selected because it is highly effective in preventing sliding.

Next, part 3 is also provided with a circular transparent light 5 at its center, so this part 3 also has an axis 1.
Although, like the pipe 2, it is difficult to slide, a rotation stopper 6 is further used to completely prevent the part 3 from rotating and sliding on the shaft 1. This rotation stopper 6
In this installation method, a rectangular flat recess 7 is formed in the center of the part 3, and a rotation stop 6 is fitted into the recess 7.
It is sufficient to provide a circular hole that completely matches the hole 5 at the center of the part 3.

(c) Effects of the invention The present invention, which has the above-mentioned configuration, has a hexagonal pillar instead of the conventional cylindrical shaft, which prevents rotational sliding with the pipe on the outside, and also allows parts to be assembled together. A similar effect can be obtained in the relationship between the shaft and the shaft, and by fitting a rotation stopper in the center of the upper surface of the part, it is possible to completely prevent the rotation of the part, unlike a conventional cylindrical shaft. When the parts rotate, all parts are kept in the same direction without changing their orientation, and in short, the shaft and parts are prevented from rotating and sliding only by making the shaft into a hexagon and fitting it to the parts to prevent rotation. Also, the rotation stopper has a decorative effect that the part itself has, and if it is attached to the top of the part, it will not become a blind spot of the part and be visible to the eye, and the weight of the part will be prevented from rotating. By making the axis hexagonal,
Not only does it have the effect of preventing parts from rotating, but even if the through hole in the center of the part has some undulations, if both parts are cylindrical, it is easy to damage one of them, and it is difficult to insert it. Moreover, if the shaft is a hexagonal prism, there is no need to worry, and it has many practical effects.
