Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a magnet ring runner.
[0002]
[Prior art]
The conventional magnet ring runner is a ring runner with a built-in magnet, and a box is integrally provided on a hook hanging from the ring, and the magnet is accommodated in the box. Therefore, the ring runner with a built-in magnet was not the same as a general ring runner.
[0003]
[Problems to be solved by the invention]
Ring runners, including ring runners with built-in magnets, are externally fitted to curtain poles from their ends, so some modifications to the order of ring runners with magnets and general ring runners, and addition or removal of ring runners with built-in magnets are partly It was a troublesome work because it was necessary to remove the ring runner from the curtain pole.
[0004]
The present invention has been made to solve this problem, and the object of the present invention is to remove the ring runner from the curtain rod in order to change, add or remove the magnet ring runner in the ring runner row. It is to be able to implement without.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the means employed by the present invention resides in that a magnet case is detachably attached to the ring runner and the magnet is accommodated in the magnet case.
The magnet case is an elastic synthetic resin molded product, and has a square box-shaped main body with one open side, an inverted J-shaped hook projecting from the upper surface of the main body, and a grip formed on the other side of the main body. It consists of parts. The main body houses two yokes and a magnet sandwiched between them. The hook part is provided with a slit except for the tip part and separated into the front and rear. When the hook part of the magnet case is hung on the ring runner, the upper part of the ring runner hook is fitted into the slit, and the lower part is fitted into the fitting groove of the fitting part. The entrance width of the hook part is slightly smaller than the outer diameter of the ring cross section of the ring runner so that when the hook part is attached to or detached from the ring of the ring runner, the hook part elastically expands.
[0006]
As a result, the magnet case can be attached to the ring runner, and since the attached magnet case has a stable posture, it plays the same role as a conventional magnet built-in ring runner. The attached magnet case can be detached from the ring runner by elastically expanding the hook portion. Therefore, the sequence change, addition, and removal of the magnet ring runner in the ring runner row fitted to the curtain pole can be performed without removing the ring runner from the curtain pole.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the examples shown in FIGS.
Hooks attached to the upper edge ends of the left and right curtains (not shown) are hooked on the hook hooks 12 of the two runners 11 at the center of the curtain pole 10. The upper circular portion 13 of the hook hook 12 is held by a ring 15, and the lower circular portion 14 has a hook hole 16. The upper circular portion 13 is concentric with the circular cross section of the ring 15 to be sandwiched, but the diameter is slightly larger than the cross section of the ring 15. Magnet cases 20 are mounted symmetrically on the two runners 11. The magnet case 20 has a box-shaped main body 21 with one open side, an inverted J-shaped hook portion 22 extended from the upper surface and hooked to the ring 15, and a hook hook 12 provided on the other side of the main body 21. The lower circular portion 14 is formed of a grip portion 23 to be fitted. A magnet 17 and a yoke 18 that holds the magnet 17 are accommodated inside the main body 21, and the pins 19 prevent the dropout. The hook portion 22 includes an inlet portion 24 that is narrower than the cross-sectional diameter of the ring 15, a fitting portion 25 having the same inner diameter as the cross-sectional diameter of the ring 15, and a slit 26 that separates portions other than the tip. The width of the slit 26 is wider than the thickness of the hook hook 12. The grip portion 23 is two parallel protrusions, and a grip groove 27 is formed between them. The magnet case 20 is a synthetic resin molded product rich in elasticity, and is attached to and detached from the ring 15 by making the opening width of the inlet portion 24 elastically larger than the diameter of the cross section of the ring 15. Further, the magnet case 20 is hooked by making the opening of the inlet portion 24 of the inverted J-shaped hook portion 22 and the inner diameter of the fitting portion 25 elastically larger than the diameter of the upper circular portion 13 of the hook hook 12. It is possible to fit in 12 or remove it. Therefore, the magnet case 20 can be detached from the curtain pole 10 without removing the runner 11.
[0008]
【Example】
A magnet case according to an embodiment of the present invention will be described with reference to the cross-sectional view of FIG. A pin hole 28 is formed in the front and rear surfaces of the main body 21 of the magnet case 20 so as to fit both ends of the pin passing through the magnet and the yoke. The slit 26 of the hook portion 22 extends from the upper surface of the main body 21 to the distal end side inlet portion 24. The grip groove 27 of the grip portion 23 formed on the other side surface of the main body 21 has a bottom that communicates with the inside of the main body 21. The reverse J-shaped hook portion 22 is separated from the front and rear inlet portions 24 and the fitting portion 25 by the slit 26, so that when it is twisted open, it is elastically deformed relatively easily and fits with the opening width of the inlet portion 24. The inner diameter of the joint portion 25 can be made larger than the diameter of the upper circular portion of the hook hook.
[0009]
As shown in FIG. 4, when the magnet 20 is moved horizontally in the direction of the arrow with respect to the ring 15 fitted to the curtain pole 18, the hook portion 22 of the magnet case 20 can be easily fitted to or removed from the ring 15. it can.
As shown in FIG. 5, after being fitted to the ring 15, the hook portion 22 of the magnet case 20 is hooked on the upper circular portion 13 of the hook hook 12 obliquely from above, and as shown by the arrow, the main body 21. Is pulled obliquely downward, the hook portion 22 is twisted to increase the opening width, and the upper circular portion 13 is fitted into the slit 26. Then, as shown in FIG. 2, when the lower circular portion 24 is fitted into the grip groove 27 of the grip portion 23, the mounting of the magnet case 20 to the ring runner 11 is completed, and the magnet ring runner is obtained.
[0010]
【The invention's effect】
As described above, the magnet ring runner of the present invention is a runner consisting of a general ring and a hook, and a magnet case is detachably mounted. Therefore, unlike the conventional magnet built-in ring runner, the magnet ring runner is attached to a curtain pole. By attaching the magnet case to the runner or by removing the attached magnet case, the excellent effect that the order position of the magnet ring runner in the runner row can be changed with the runner attached to the curtain pole. Play.
