Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a curtain such as a back door window of a one-box type automobile.

[0002]

2. Description of the Related Art FIG. 5 is a double-opening type curtain applied to a curtain such as a back door window of a one-box type automobile. The curtain rail (1) attached to the upper edge of the window has left and right curtains. A pair of curtains
(2,3) is slidably supported by slidable. Permanent magnets (4,5) are attached above and below the mating edges of the curtains (2, 3) respectively, and the permanent magnets of both curtains (2, 3) are attached.
The curtains (2, 3) are made by stacking (4,5) on top of each other and magnetically attaching them.
Is locked closed.

[0003]

In the above conventional structure, when the magnetic force of the permanent magnets (4,5) of both curtains (2, 3) is weak, the permanent force is applied by the inertia force when closing the curtains (2, 3). Magnet (4,5)
They repel each other and are easily separated, and when the curtains (2, 3) are both closed, the permanent magnets (4,5) are not easily magnetized unless both are securely overlapped. Moreover, the permanent magnets (4,5) of both curtains (2, 3) are easily separated due to vibration while the vehicle is running. On the other hand, when the magnetic force of the permanent magnets (4,5) is strong, a large force is required to separate the curtains (2, 3), and the thrust of the electric linear motor curtain is small and cannot be separated. Also, if the thrust of the electric wire type curtain is large, the seam of the curtains (2, 3) may be broken.

[0004]

As a means for solving the above-mentioned conventional problems, the present invention is directed along one edge of a curtain (2) slidably supported by a curtain rail (1). A member to which the electromagnet (14) or a pair of upper and lower permanent magnets are attached, and one end of the curtain (2) is fixed.
A pair of upper and lower permanent magnets (15A, 15B) or electromagnets are attached to (3), and one end of the electromagnet (14) of the curtain (2) or member is attached to the permanent magnet (3) of the member or curtain. 15
A curtain fixing structure is provided in which the north poles of A, 15B) face each other and the south poles of the permanent magnets (15A, 15B) face the other end of the electromagnet (14). The member (3) provides a curtain fixing structure in which the member is a curtain or a pillar garnish.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIGS. In the figure, a pair of left and right curtains (2, 3) are slidably supported on the curtain rail (1) attached to the upper edge of the window, and the curtain rail (1) is attached along the edge of one curtain (2). Electromagnet (14) is attached to the other curtain (3) at the mating edge of the curtain (3).
5B) is installed. As shown in FIGS. 3 and 4, the electromagnet (14) and the permanent magnets (15A, 15B) are the curtains.
They are attached to the bag parts (2A, 3A) formed on the edges of (2, 3) in a housed state, and the upper permanent magnet (15A) corresponds to the upper end of the electromagnet (14). , The permanent magnet (15A) has an N pole facing the upper end of the electromagnet (14), and the lower permanent magnet (15B) corresponds to the lower end of the electromagnet (14).
5B) has an S pole facing the lower end of the electromagnet (14).

As shown in FIG. 2, the electromagnet (14) has an iron core (14).
A) and the coil (14B) wound around the iron core (14A)
The coil (14B) of the electromagnet (14) is supplied with current from the power supply (18) through the electric wire (17) in the harness (16) arranged along the curtain rail (1). The switch (19) is interposed in the circuit.

In the above structure, in order to secure the fixing of the curtains (2, 3) to each other, the permanent magnets (1
If the magnetic force of (5A, 15B) is strong, turn off the switch (19) and close the curtain (2, 3) to close the permanent magnet of the curtain (3).
(15A, 15B) on the electromagnet (14) of the curtain (2), the permanent magnet (15A, 15B) the iron core (14A) of the electromagnet (14)
Both curtains (2, 3) are fixed in the closed state by magnetically adhering to them. When separating and opening both curtains (2, 3), the switch (19) is turned on and a current flows in the direction of the arrow in FIG. Then, the electromagnet (1
Since the upper end of 4) becomes the N pole and the lower end becomes the S pole, the N pole and the permanent magnet (15A) of the permanent magnet (15A) of the curtain (3) are
The electromagnet (14) and the permanent magnets (15A, 15B) are automatically dissociated by repelling the S pole of B). Therefore, the permanent magnet (15A, 15
Even if the magnetic force of B) is increased to ensure the mutual fixing of the curtains (2,3), the curtains (2,3) can be easily pulled apart and opened.

When the permanent magnets (15A, 15B) of the curtain (3) are weakened to facilitate the separation of the curtains (2, 3), the switch (19) is turned on to turn on the electromagnet (14). ) In the direction opposite to the arrow shown in FIG.
When (15A, 15B) are turned upside down, the S pole of the permanent magnet (15B) faces the N pole of the electromagnet (14), and the S pole of the electromagnet (14) faces the permanent magnet (15A). The N poles of the two become opposite to each other, the permanent magnets (15A, 15B) are strongly magnetically attached to the electromagnet (14), and the curtains (2, 3) are securely fixed to each other. And when separating the curtain (2, 3), switch (19)
When turned off, the magnetic force of the permanent magnets (15A, 15B) is weak and can be easily separated.

In the above embodiment, a pair of right and left curtains are arranged and the mating edges of both curtains are fixed. However, in the present invention, only one curtain is arranged, and an electromagnet or an electromagnet is attached to one edge of the curtain. A permanent magnet may be attached, and a permanent magnet or an electromagnet may be attached to a pillar garnish or the like, which is a member to which one end edge of the curtain is fixed.

[0010]

Therefore, in the present invention, the curtain is securely fixed in the closed state, and can be easily separated when opened.
