JP7031052B1 - Quiet curtain rail using the repulsive force of a magnet - Google Patents

Abstract

【Task】
Providing curtain rails that suppress the sound of opening and closing curtains in situations where quietness is required in environments such as nighttime and childcare.
SOLUTION:
Place the runner of the permanent magnet in the center of the rail made of non-magnetic material, place the N pole of each of the inner permanent magnets diagonally below the left and right on the runner side, and place the S pole on the outside, and lift the curtain with repulsive force to make contact. Move without moving and keep quiet.

Description

The present invention relates to a silent curtain rod utilizing the repulsive force of a magnet.

There are times when quietness is required when opening and closing the curtain, and various methods have been introduced.

We would like to provide curtain rods that suppress the sound of opening and closing curtains in situations where quietness is required in environments such as nighttime and childcare.

Permanent magnet when opening and closing the curtain N pole side of the front side and the rear side of the traveling direction of the runner body
A non-magnetic hook hook is attached to the runner body of a permanent magnet whose corners are chamfered with curves.
C-shaped, with the central opening facing down, placed in the center of the rail made of non-magnetic material with a cross-sectional shape used as a runner runway, and the N poles of the inner permanent magnets diagonally below the left and right sides are on the runner side. Permanent magnets with a specific magnetic force that take into account the repulsive force that lifts a curtain with a length of about 15 mm with the S pole on the outside are mounted side by side at the corners of the runner at an angle toward the center, due to the repulsive force between the N poles of the permanent magnets. The runner that lifted the curtain was arranged to float, and the runner and the permanent magnets attached to the inside diagonally below were moved smoothly without contact with each other to maintain quietness.

No noise was generated due to the friction between the rail and the runner, and quietness was maintained.

FIG. 1 is a cross-sectional view of the front surface of a silent curtain rod using the repulsive force of a magnet. FIG. 2 is a cross-sectional view of a side surface of a silent curtain rod using the repulsive force of a magnet. FIG. 3 is a cross-sectional view of the upper surface of a silent curtain rod using the repulsive force of a magnet.

An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 is a cross-sectional view of the front of a silent curtain rod using the repulsive force of a magnet, showing a state in which the runner floats due to the repulsive force.

FIG. 2 is a cross-sectional view of the side surface of a silent curtain rod using the repulsive force of a magnet, showing that it can cope with the inclination of the runner when the curtain is opened and closed.

FIG. 3 is a cross-sectional view of the upper surface of a silent curtain rod using the repulsive force of a magnet.

FIG. 1 is a representative diagram of the present invention.

Prevents noise from friction between rails and runners in places when quietness is required.
