Description

Detailed Description of the Invention (Industrial Field of Application) This invention provides a method for reliably holding a window glass at a desired opening position and moving the window glass for opening and closing the window opening. This invention relates to a locking device for an automobile window that can be easily operated.

(Prior Art) Conventionally, there are automobile windows in which a window opening formed on the side surface of the vehicle body is opened and closed by moving the window glass in the front and back direction, such as the one shown in FIG. 6. There is.

In the figure, 51 is a car body panel that constitutes the side wall of the car body.
A window opening 52 is formed in this vehicle body panel 51.

The opening edge 53 of this window opening 52 has this opening edge 5
A wind frame 55 is provided extending along 3,
A symmetrical glass run 56 having a substantially U-shaped cross section is attached to the recess formed in the wind frame 55. This glass run 56 is connected to the window glass 54.
is fitted so as to be slidable back and forth, and by sliding this window glass 54 back and forth, the window opening 52 can be opened to a desired degree.

(Problems to be Solved by the Invention) By the way, in the above-mentioned conventional configuration, the window glass 54 is simply slidably fitted into the glass run 56, so when the car suddenly starts or stops, there is a large inertia. When force acts on this windshield 54, the windshield 54
There is a risk that the glass run 56 may slide unexpectedly.

Therefore, in order to prevent the window glass 54 from sliding unexpectedly, a glass run 56 is pressed against the window glass 54 with a relatively large elastic force.

As a result, it is possible to hold the window glass on the vehicle body side at a position where the window opening 52 is opened to a desired degree.

However, if this is done, the operation of moving the window glass 54 back and forth becomes difficult, which causes the inconvenience that it becomes difficult to open and close the window.

(Object of the Invention) The present invention was made in view of the above-mentioned circumstances, and it is possible to securely hold a window glass in a desired position with the window opening at a desired opening, and to open and close the window opening. To make it easier to open and close the window by making the movement easier when moving the window glass.

(Structure of the Invention) A feature of the present invention for achieving the above object is that a guide rail for guiding the window glass in the front and back direction is provided on at least one of the upper and lower opening edges of the window opening. A pair of front and rear lock arms are pivotally supported on the windshield so as to be able to move up and down, respectively, and when the locks 7-m rotate, the two lock arms are mounted so that their rotating ends are frictionally joined to the guide rail. The lock arms are interlocked with each other, and a spring is provided which urges the lock arms in the rotational direction to bring them into frictional contact with the guide rail.

(Example) Hereinafter, an example of the present invention will be described with reference to the fifth factor from FIG.

In FIG. 2, 1 is a car, 2 is the body of the car, and arrow Fr in each figure indicates the front of the car l. A side door 3 is provided on the side surface of the vehicle body 2 in the middle of the front and back.

This side door 3 has a door opening 4 formed in the vehicle body 2,
The vehicle body 2 has a sliding door 5 that is slidable back and forth along the outer surface of the vehicle body 2. When the sliding door 5 moves backward, the door opening 4 is opened, and when the sliding door 5 moves forward, the door opens. 4 is considered closed.

Further, a rear quarter window 6 is provided on the side surface of the vehicle body 2 behind the side door 3. This rear quarter window 6 has a quarter window opening lower which is fixed to the vehicle body 2, and a quarter window glass 8 which is fixed to the opening edge of this quarter window opening lower when the quarter window opening lower is closed. There is.

A door window 10 is provided above the sliding door 5. This door window 10 is shown in FIGS. 2 and 3.
I will explain about it.

The door window 10 includes a window opening 11 formed at the top of the sliding door 5, and a single window that is supported by the opening edge 12 of the window opening 11 and opens and closes the window opening 11 as the vehicle body 2 moves in the longitudinal direction. It has glass 13.

The opening edge 12 is provided with a wind frame 15 extending along the opening edge 12. A weather strip 16 is attached to the outer edge of the wind frame 15. Further, guide rails 17 and 17 are attached to an upper frame (not shown) and a lower frame 15a, which constitute the wind frame 15, respectively.

Both guide rails 17.17 are made of resin and have guide grooves 18 extending in the longitudinal direction of the vehicle body 2 and having a U-shaped cross section.

On the other hand, a pair of upper and lower front sliders 20 and a rear slider 20' are protruded from the front end and the middle part of the windshield 13, respectively. The front slider 20 of these two tank movers
has a substantially perfect circular cross section, and is fitted into the guide groove 18 so as to be rotatable about its axis and slidable back and forth. On the other hand, although the rear slider 20' is also not shown, it is fitted into the guide groove 18 so as to be slidable back and forth.
0' is designed to move the rear end of the window glass 13 outward in the vehicle width direction as the window glass 13 moves back and forth.

Then, when the window glass 13 is moved backward, both tank movers 20 and 20' slide backward in the guide groove 18.
Although not shown, the front end of the windshield 13 moves inward from the outside surface of the vehicle body, and the rear end of the windshield 13 moves toward the outside of the outside surface of the vehicle body behind the window opening 11. It becomes a tilted posture. Furthermore, when the windshield 13 is moved backward, the windshield 13 moves while maintaining the above-mentioned tilted posture,
This allows the window opening 11 to be adjusted to a desired opening degree.

Furthermore, when the windshield 13 is moved forward, the rear end of the windshield 13 moves toward the inside of the vehicle as the two tank movers 20, 20' slide forward in the guide groove 18.
As a result, the inside surface of the windshield 13 comes into pressure contact with the outside surface of the weather strip 16, and the window opening 11 is completely closed. In this case, the outer surface of the window glass 13 is substantially flush with the outer surface of the vehicle body 2, as shown in FIGS. 1, 3, 4, and 5.

In the above configuration, a locking device 22 is provided to lock the window glass 13 to the vehicle body side. This locking device 2
2 will be explained with reference to FIGS. 1, 4, and 5.

The locking device fi22 is a locking means 23 that locks the window glass 13 that fully closes the window opening 11 to the vehicle body.
and a holding means 24 for holding the window glass 13 with the window opening 11 at a desired opening degree on the vehicle body side at that position.

First, the locking means 23 will be explained.

A box-shaped bracket 26 is screwed to the interior side of the window glass 13, and a front-rear midway portion of a locking arm 27 is pivotally supported at the front end of the bracket 26 so as to be rotatable about a vertical axis. A locking hook 2B is formed at the front rotating end of the locking arm 27, while the rear rotating end of the locking arm 27 serves as an operating portion 29 of the locking arm 27. Further, a locking piece 30 for releasably locking the locking hook 28 is welded to the front frame 15b constituting the wind frame 15. Furthermore, a locking spring 31 is provided which urges the locking arm 27 in a direction (indicated by arrow A in FIG. 5) to lock the locking hook 28 to the locked piece 30.

Then, when the operating portion 29 is pushed toward the outside of the vehicle against the biasing force of the locking spring 31, the locking arm 27 rotates and the locking tool 28 is released from the locked piece 30. , This releases the locking of the windshield 13 from the vehicle body.

On the other hand, the holding means 24 has a pair of front and rear first and twentieth grip arms 33, 33'. Of these two lock arms 33, 33', the tenth lock arm 33 has its middle portion pivoted to the lower end of the bracket 26 by a first pivot shaft 34. The tenth hook arm 33 is bent at its upper and lower middle portions to form a dogleg shape, and a rubber member 35 is externally fitted to the lower rotating end 33a. The rubber member 35 is fitted into the guide groove 18 of the guide rail 17, and the rubber member 35 is frictionally bonded to the guide rail 17.

On the other hand, as shown in FIG. 1, the 20th arm 33' has almost the same configuration as the lower part of the 10th arm 33 and is symmetrical.
a second shaft whose upper end has an axis parallel to the first pivot shaft 34;
It is pivoted to the lower end of the bracket 26 by a pivot shaft 34'. A rubber member 35' is fitted onto the rotary end 33a' of the 20th hook arm 33', and this rubber member 35' is fitted into the guide groove 18 and friction-bonded to the guide rail 17.

Also, gears 37 and 37' that engage with each other are formed at the upper and lower midpoints of the tenth hook arm 33 and the upper end of the twentieth hook arm 33', which are opposed to each other. As a result, the rotating end 33a' of the 20th hook arm 33' and the lower rotating end 33a of the 10th hook arm 33 are interlocked and rotated in opposite directions.

Further, the upper rotating end 33b of the tenth arm 33 is fitted into the bracket 26, and as shown in FIGS. 1 and 5, there is a gap between the front end of the bracket 26 and the upper rotating end 33b. A spring 36 is interposed therebetween. This spring 36 has the guide groove 18 on the lower surface of both the rubber members 35 and 35'.
The upper rotating end 33b of the tenth hook arm 33 is biased in the direction of press-contacting and friction-bonding the inner bottom surface of the tenth arm (as shown in FIG. 1 and arrow B in FIG. 1).

In addition, the lower surfaces of both the rubber members 35 and 35' and the guide groove 18
An operating lever 38 is provided for rotating both lock arms 33, 33' in order to release the frictional connection with the inner bottom surface of the lock arm 33, 33'. The operating lever 38 is supported by the bracket 26 so as to be slidable back and forth, and the front end 38a of the operating lever 38 is in contact with the upper rotating end 33b of the tenth arm 33, as shown in FIGS. 1 and 5. are in contact with each other. Further, a plate-shaped projection 39 is formed on the bracket 26 between the operating portion 29 of the locking arm 27 and the operating lever 38 so as to project toward the inside of the vehicle. Reference numeral 40 denotes a cover, and this cover 40 covers the upper and lower middle portions of the 10th pull arm 33 and the upper part of the 20th pull arm 33' located between the bracket 26 and the guide rail 17 from the inside of the vehicle.

If the operating lever 38 is pushed forward against the biasing force of the spring 36 (as shown in FIG. 1 and arrow C in FIG. 1), the upper rotating end 33b of the tenth arm 33 will rotate forward. As a result, the lower rotating end 33a of the 10th claw arm 33 rotates upward, and in conjunction with this lower rotating end 33a, the rotating end 33a' of the 20th claw arm 33' rotates upward. 1), both the rubber members 35 and 35' are separated from the guide groove 18 (as shown by the dashed-dotted line in FIG. 1), thereby reducing the friction between the guide rail F and both lock arms 33 and 33'. The bonding force is weakened, and the holding of the windshield 13 against the vehicle body by the holding means 24 is released.

When the push of the operating lever 38 is released from the above state, the upper rotating end 33b of the tenth hook arm 33 rotates rearward due to the biasing force of the spring 36, and the operating lever 38 moves rearward (see Fig. 1). and arrow E shown in FIG.
The 20th arm 33 is linked to this lower rotating end 33a.
The rotating end 33a' of the rubber member 35' also rotates downward (as shown by the solid line F in FIG. (shown with solid lines in the figure), this allows the guide rail 17 and both lock arms 3 to
3.33' is strengthened, and the windshield 13 is prevented from moving back and forth with respect to the vehicle body. In this case, if one of the two lock arms 33, 33', for example, the 20th lock arm 33', rotates downward, the other first
The zero lock arm 33 also rotates downward, and as a result, both lock arms 33 and 33' firmly press against the guide rail 17, and the upper rotating end 33b of the tenth lock arm 33 firmly contacts the front end 38a of the operating lever 38. I will come into contact with you. Moreover, the same thing happens even if, contrary to the above, the tenth hook arm 33 rotates downward first.

As shown in FIGS. 1 and 5, when the window glass 13 and the window opening 11 are fully closed, it is locked! I2
When attempting to release the lock 2 and move the window glass 13 to make the window opening 11 the desired opening degree,
The occupant only has to use his/her fingers to push the operation part 29 of the locking arm 27 and the operation lever 38 of the lock arm 33 in the direction of pinching the protrusion '39 (as shown by reference numeral H in FIG. 5). , locking arm 27 and both locking arms 33.3
3' rotate together, and the locking means 23 and the holding means 24
Both the locking and holding of the windshield 13 to the vehicle body by the above are released, thereby allowing the windshield 13 to move back and forth (as shown in FIG. 1 and arrow G in FIG. 1).

Then, the occupant moves the window glass 13 to a position where the window opening 011 is set to the desired opening degree while holding the operating lever 38 and the protrusion 39 between the fingers, and releases the finger at this position. Due to the urging force of 36, the first
As the 0-lock arm 33 rotates, the 20th lock arm 33' also rotates in conjunction with the 10th lock arm 33, and these two lock arms 33 and 33' are connected to the guide rail 17.
Strong friction bonding. As a result, the windshield 13 is held on the vehicle body side in the above position.

Further, when the window opening 11' is to be fully closed, the passenger can move the windshield 13 forward by pinching the operating lever 38 and the protrusion 39 with his or her fingers. When the window opening 11 is closed, the locking hook 28 is automatically locked to the locked piece 30.Next, when you release your finger from the operating lever 38, both lock arms 33 and 33' are attached to the guide rail 17. Friction bonding is performed, whereby the windshield 13 is more reliably locked toward the vehicle body when the window opening 11 is fully closed. Such operations can be performed by the passenger with one hand.

(Effects of the Invention) According to the present invention, a guide rail for guiding the window glass in the front-rear direction is provided on at least one of the upper and lower opening edges of the window opening, and a lock arm is rotatably attached to the window opening. In addition to being pivotally supported, the rotating end of the lock arm can be frictionally joined to the guide rail by rotation, and a spring is provided that biases the lock arm in the rotational direction to frictionally join the lock arm to the guide rail. If the window glass is moved to set the window opening to the desired opening, and then the lock arm is friction-bonded to the guide rail by the biasing force of the spring, the window glass will be securely held against the vehicle body at the above-mentioned moving position. be done. Therefore, even if a large inertial force acts on the windshield when the vehicle suddenly starts or stops, the windshield will not move unexpectedly and the window opening will be maintained at the desired opening.

Moreover, in this invention, the lock arms are provided as a pair of front and rear lock arms, and when one lock arm is frictionally joined to the guide rail, the other lock arm is also automatically frictionally joined to the guide rail in conjunction with this. Because I did it like this,
The frictional connection of the lock arm to the guide rail becomes more reliable.

Furthermore, since the frictional connection of the lock arm to the guide rail can be released, when moving the window glass back and forth, the movement of the window glass can be made easier by releasing the frictional connection. It can be easily done.
