DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatically opening/closing sliding window for a vehicle.

[Conventional technology]

Large vehicles such as buses and trucks are equipped with sliding windows that open and close in the front and rear directions. Figure 7 is from 1986-26.
918 is a perspective view showing a conventional sliding window for a vehicle; FIG. In the figure, 1 is a sliding window, and is provided with a fixed window plate 2 and a slidable sliding window plate 3. A window plate holder 4 made of a metal plate is attached to the lower end of the sliding window plate 3, and is connected to a connecting member 6 via a movable plate 5.
It is adapted to be moved by a cable 7 such as a wire.

[Problem to be solved by the invention]

In the conventional sliding window for a vehicle as described above, the window plate holder 4 is connected to the connecting member 6 via the movable plate 5, so that the driving force by the cable 7 is transmitted to the window plate holder 4 with a time difference. Because of this, the running of the sliding window board 3 is unstable, and since the cables 7 move away from the window board holder 4, stress is applied to the window board holder 4 during movement, causing the sliding window board 3 to wobble. There was a problem.

In addition, methods have been proposed in which the sliding window plate 3 is moved using racks and pin-ons, or moved using brackets, etc. (Utility Model Application No. 57-29785,
No. 7-181880, No. 58-67061), both require a large space to move the sliding window plate 3, the movable parts are exposed indoors, which is dangerous, and the appearance is unsatisfactory. In order to solve the above-mentioned problems, it is an object of the present invention to provide a sliding window for a vehicle whose sliding window plate can be smoothly opened and closed using a small space. It is.

[Means to solve the problem]

This invention includes a sliding window plate that slides horizontally;
A window plate holder attached to the lower end of this sliding window plate,
a guide channel having a sliding groove that accommodates the window plate holder so as to be able to slide in the horizontal direction; an endless cable that is fixed to the window plate holder and moves within the sliding groove; Kakeru to drive! ! This is a sliding window for a vehicle having an II device.

[For production]

In the sliding window for a vehicle of the present invention, when the cable is moved by the drive device, the window plate holder fixed to the cable moves within the sliding groove of the guide channel, and the sliding window plate opens and closes. At this time, the driving force of the cable is applied directly to the window plate holder, and no stress is applied to the window plate holder, so the window plate holder moves smoothly in the sliding groove, and there is no time difference or wobbling with the drive device. do not.

In the present invention, a window plate holder is attached to the lower end of the sliding window plate, and a part of the endless cable stretched to this window plate holder is fixed, so that the window may become loose. It slides smoothly without any problems. Since the window plate holder slides within the sliding groove of the guide channel, there is no danger, and the kite channel can prevent dirt, rainwater, etc. from entering the door panel. Also, since a part of the endless cable is fixed to the window plate holder, tension is applied to the cable itself when the cable is stretched, but no tension is applied to the window plate holder, so the cable is stretched. Even if the window board holder is stretched, the window board holder will not come off from the window board.

If the window plate holder contacts the guide channel at the protruding portion, sliding resistance is reduced and the window plate can be slid smoothly. Also, when installing window plate holders in front and behind the window plate, when the window plate is moved horizontally, it is necessary to fix a part of the cable to the window plate holder on the side where the sliding resistance is greater in the moving direction of the window plate. For example, the window panel can slide smoothly.

That is, the window plate can be slid by pulling it in a direction where the sliding resistance is large, and pushing it in a direction where the sliding resistance is small.

When tensioning the cable, use a one-way clutch so that it rotates in only one direction, so that the tensioned cable will not stretch due to vibrations while driving.
No wobbling of the window board occurs.

is provided. The cable 7 is made of wire or the like, and both ends thereof are inserted into the tubular connecting member 6 and caulked to become endless, and the connecting member 6 is accommodated in the engaging recess 29 of the window plate holder 4 and engaged. ing. Cable 7 is guide channel 1
6 is guided by guide members 31, 32, and 33 such as reels from both ends, and is moved by a drive unit hflll. 34 is a conduit.

The drive device 11 includes a take-up bobbin 35 for winding the cable 7, a drive unit 37 such as a motor that drives the take-up bobbin 35 via a deceleration mechanism 36 such as a worm and a gear, and a tension device 38.
These are attached to a bracket 39. Both ends of the cable 7 are fixed to a winding bobbin 35.

The tension device 38 includes a guide member 41 attached to the bracket 39, a one-way clutch 42 attached coaxially with the guide member 41, and a swing arm 43 that can swing in one direction by the one-way clutch 42. It consists of a guide member 44 provided at the tip of the swing arm 43 and a spring 45 that pulls the swing arm 43. The one-way clutch 42 allows the swing arm 43 to swing in the direction in which the spring 45 is pulled (Y direction), and prevents the swing arm 43 from swinging in the opposite direction.

In the above configuration, when the drive unit 37 is started, the take-up bobbin 35 rotates via the deceleration mechanism 36, and the cable 7 starts moving. When starting, an excessive load is applied to the cable 7, so in the conventional tension mechanism consisting only of the spring 45, it swings in the counter-Y direction against the tensile force of the spring 45, resulting in a delay in opening/closing and a shock. However, in this embodiment, the one-way clutch 42 prevents rocking in the opposite Y direction, so no time delay, impact, noise, etc. occur. Furthermore, loosening of the cable 7 due to elongation of the cable 7 or the like is resolved by being pulled by the spring 45, and the cable 7 is maintained in a tensioned state.

Due to the movement of the cable 7, the window plate holder 4 that engages with the connecting member 6 moves within the guide channel 16, and the sliding window plate 3
opens and closes.

At this time, a seal molding 23 is attached to the guide channel 16, and the lips 25 press the slide window plate 3 from both sides, and in the areas where the slide window plate 3 is not present, the lips 25 abut each other and the guide channel 1
Since the opening 20 of the guide channel 16 is covered, foreign objects such as sand and water are prevented from entering the sliding groove 19 of the guide channel 16.

Therefore, opening and closing of the sliding window plate 3 is not hindered, and damage to the sliding window plate 3 is prevented even if the cable 7 is forcibly pulled by the drive unit 37 such as a motor. Furthermore, since the window plate holder 4 is formed with the protruding parts 21, the sliding resistance is reduced, and even if small pieces of sand etc. enter, they are accommodated in the spaces 22 formed between the protruding parts 21, and the sliding resistance is reduced. does not inhibit.

The driving force of the cable 7 is then applied directly to the window plate holder 4,
Since no stress is applied to the window plate holder, the window plate holder 4 moves smoothly within the sliding groove 19, and no time difference or wobbling occurs in the drive device 11.

〔Effect of the invention〕

As described above, according to the present invention, the cables are fixed to the window plate holder that supports the sliding window plate, and are slid within the guide channel having the sliding groove. Window panels can be opened and closed smoothly.
