Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly applies to the side portions of cab-over type wagons;
This invention relates to a curtain mechanism for automobiles that can be used as an opening/closing mechanism for a curtain hung in a partition at the rear.

Curtains for automobiles used to be hung on curtain rails and opened and closed manually, just like ordinary curtains for the bottom of a house, but as the number of cab-over type wagons has increased recently, the number of curtains has also increased. There is a growing demand for automobile window curtains that can be opened and closed automatically from the driver's seat using an electric motor.

In a conventional motor-driven curtain mechanism, a slider is fixed to a wire, and the curtain is opened and closed when the slider comes into contact with a stopper disposed on the side of a curtain rail.

However, since the stopper and the slider come into contact with each other, the wire will continue to be pulled unless the motor is stopped, resulting in an overload on the wire and the motor. Therefore, there were disadvantages in that the strength of the wire had to be improved and the motor had to be durable.

The present invention was proposed in response to the above-mentioned needs, and includes a curtain rail that is attached to the inner upper edge of an automobile window where curtains need to be hung, and a curtain rail that is arranged along the curtain rail and that is moved by the drive of a motor. A wire that suspends the curtain and a plurality of sliders that can move within the grooves of the curtain rail.A plurality of sliders are attached to the sides of the curtain and move together with the wire when there is no resistance, but when resistance is applied, only the wire moves. A slider with a friction member that is movably engaged in frictional engagement with the wire is filled and fixed in a cylindrical portion through which the wire passes, and the slider with the friction member and the slider located at the other end of the curtain are provided. 1 attached to both sides of the curtain rail so as to be in contact with each other.
An object of the present invention is to provide a curtain mechanism for an automobile, which has a structure consisting of a pair of stoppers and whose purpose is to prevent overload from being applied to the wire or motor even if the slider contacts the stopper in the curtain opening/closing position. It is something to do.

The present invention will be described below with reference to the embodiments shown in the drawings. Fig. 1 is a side view showing the inside of a cab-over type wagon, Fig. 2 is a plan view of the same with the roof removed, and 1a, 1b and 2 are side views. Window curtains, 3
A and 3b are rear window curtains, and 4a and 4b are partition window curtains.

Each curtain is suspended using appropriate hanging fittings (not shown) through holes 6 in the lower parts of the sliders 5, 5a shown in FIGS. 2 and 4, and the sliders 5, 5a are attached to the upper edges of each window The curtain rail 7 can be moved along a curtain rail 7 installed in the curtain rail 7. Each of the sliders 5 and 5a has a wire 9 (the inner wire is 9a and the outer wire is 9b) passed through the upper cylindrical body part 8, and unlike the slider 5, the slider 5a is different from the cylindrical body part 8. A friction member 10 made of rubber, synthetic resin, etc. is filled and fixed inside. The wire 9 is passed through the hole in the center of the friction member 10 of the slider 5a, and the two are frictionally engaged and move as one. When it comes into contact with the stopper 11a provided on the side of the
The movement of the slider 5a is stopped so that only the wire 9 can pass through the friction member 10 and move.

Several sliders are attached to one curtain, and although the number is different between FIG. 1 and FIG. 2, the number is reduced to three in FIG. 2 for convenience of explanation. That is, one slider 5a is attached near the center of the window of each curtain (when opening and closing the curtain from both sides), and this slider 5a
is adapted to come into contact with the stopper 11a. Further, a slider 5 attached to the other end of each curtain comes into contact with the stopper 11 on the other side of each curtain rail 7.

On the other hand, the wires 9a and 9b are provided parallel to each other so as to be movable along the curtain rail 7 at the upper edge of each window, and both ends of each wire 9a and 9b are wound around a drum (not shown) that is rotated by the drive of a motor 12. and are designed to reciprocate in opposite directions. The motor 12 can be of any type, such as an electric type or an air type, and can be started and stopped from either the driver's seat 13 or the passenger seat. In the figure, 14 is a back door, and 15 is a side door.

Next, to explain the operation, the curtains 1a, 1b, 2, 3a, 3b, 4 are closed as shown in Fig. 2.
In order to open wires a and 4b, the wires 9a and 9b are wound around a drum (not shown) by driving the motor 12 so that they move in opposite directions as shown by the arrows, and are then rewound. In this case, the slider 5a attached to one side of each curtain has wires 9a, 9
b moves in the direction of the arrow while pushing each curtain open, and the slider 5 provided in the middle of each curtain does not move together with the wires even if the wires 9a and 9b move; When the slider 5a approaches the position of these sliders 5, it is pushed by the curtain part that is being opened and moves. The slider 5 located at the side end of the curtain opposite to the slider 5a remains in contact with the stopper 11 and does not move its position until each curtain is completely opened. In this case slider 5a
When the wires hit each slider 5 and cannot move, only the wires 9a and 9b move, and the curtains of each part are completely opened.

Next opened curtains 1a, 1b, 2, 3a,
3b, 4a, 4b, by rotating the motor 12 in the opposite direction, the wires 9a, 9b are closed.
moves in the opposite direction to the arrow in FIG. 2, and each curtain begins to move in the closing direction as it is pulled by the slider 5a, which moves together with the wires 9a and 9b. In this case, even if the slider 5a attached to the curtain at the smallest window width first comes into contact with the stopper 11a and cannot be moved, the curtains at the other wide windows are not completely closed, so the wire 9
Only a and 9b are the friction members 1 of this slider 5a.
0 until the sliders 5a of the other curtains all come into contact with the stoppers 11a. As a result, the curtains on all windows are completely closed, resulting in the state shown in FIG. Moreover, even if the curtain is completely opened and closed, the wires 9a, 9
Since only wire b can move, the load on the wires 9a, 9b and the motor 12 due to continued driving of the motor 12 can be reduced.

Since the present invention is configured as described above in detail, even if the slider with a friction member stops moving directly by the stopper on that side or by the stopper on the other side via another slider, the wire will not move. Since the friction member can be moved independently, the window curtain can be completely closed simply by driving the motor.
Alternatively, the curtain can be opened, and although it has a simple structure, the load on the motor and wires that occurs after the curtain is fully opened or closed can be reduced, and its durability can be significantly improved. As described above, according to the present invention, even if the slider contacts the stopper in the opening/closing position of the curtain, overload can be prevented from being applied to the wire or the motor, and the effect is extremely excellent.
