Description

[Detailed description of the invention] The present invention is a novel device for lifting and lowering vehicle window glass.

For details, see 111 during sliding window glass during lifting/lowering operations.
We are trying to provide a new vehicle window glass lifting device tm that can be used to raise and lower the window glass smoothly by suppressing the @ and smoothly raising and lowering the window glass.

Problems with the conventional vehicle breath glass lifting device are illustrated in FIGS. 1 and 2. Figures 1 and J show the conventional lifting device pipe IIW! 4. In the figure, . is a guide fixed to the frame of a car door, for example.
A tape made of acid-containing resin (not shown) is arranged in a slidable manner.

b is a sprocket wheel rotatably supported on the door frame, and is rotated manually or by an appropriate drive source such as a motor.

This sprocket wheel b is meshed with the tape, so that the skeleton tape slides within the guide 6 in accordance with the rotation of the sprocket wheel. C is a connecting body that connects the window glass d and the tape inside the guide 6. Therefore, in such a lifting device K, when the sprocket wheel b is rotated and the tape meshing with the sprocket wheel b is slid up and down within the guide 6, it is combined with the skeleton tape and connected to the connector body. It is raised or lowered therewith and is therefore raised or lowered via the pane series C'.

By the way, in such a conventional lifting device, the window glass d and the tape covering the movable body are connected at only one point. Moreover, the window glass d that is raised and lowered is generally formed so that the length of the edge K1m is shorter than the length of the rear edge 1 and the width in the front and back becomes narrower at the top 11, as shown in FIG. The longer trailing edge of the glass guide is guided by touching the glass guide with a gold edge. As a result, the upper end of the front edge is subjected to a counterclockwise rotational moment while being raised and lowered, and the upper end of the front edge comes into point contact with the window frame, and the dust is concentrated at the contact point K. The movement of the window glass d appears to be a bit stiff or p, and the window glass d
It is difficult to move up and down smoothly. Therefore, the operability is extremely poor, and, for example, if a motor is used to
If you try to raise or lower the
This causes problems such as burnout of the motor.

The present invention was made in an attempt to solve the above-mentioned drawbacks of the conventional elevating device, and is a novel method that prevents the window glass from swinging during the elevating operation and allows smooth elevating and lowering of the window glass. This is intended to provide a device for lifting and lowering wheel window glass, which includes a window glass whose front and rear inner edges at least one edge is guided by a glass guide extending downward on the road to move up and down. A large number of mooring structures such as flexible synthetic resin tapes, spheres, abacus veins, etc. are connected by flexible eel-shaped bodies, and a drive cable body such as a nine-chain chain is slid on the cable body. a movably guided cable guide; a drive section that raises or lowers the drive cable body along the cable guide manually or by an appropriate power source; and a portion of the drive cable body that moves up and down along the cable guide. and a pair of transmission members respectively fixed to the window glass, at least one of the pair of transmission members is provided with an engagement protrusion, and the other is provided with an engagement set, and the engagement protrusion and the engagement groove are respectively open. The drive cable is inclined upwardly from the side of the edge of the glass guided by the glass guide to the opposite side, and the engagement protrusion and the engagement groove are slidably engaged with each other, and the drive cable It is characterized in that a driving force for raising and lowering the window glass is transmitted from the body through the pair of transmission members to the window glass so that the body moves.

The front edge of the window glass to which the transmission member λl is fixed has a length J
/ is the length of the trailing edge l, - is shortened, and the width in the front-rear direction is narrower at the upper part 11, and is narrower in shape H.・ 10 is a window frame, and the cross-sectional shape is formed so that the periphery excluding the lower edge of the T-less window glass 2-2 is fitted into it. 9 is its leading edge structure! Of and the trailing edge member JOr extend downward to the window glass. It is designed to guide you.

Accordingly, in the above-mentioned wheel window glass lifting device of the present invention, the sprocket wheel can be operated by the screen or by manual operation. When is rotated, the drive chain/4C is raised or lowered within the guide lO depending on the direction of rotation. Therefore, the transmission member core 7, which is attached to the drive chain 1 through the bracket 01r, is also raised or lowered, and the movement of the window glass is carried out through the transmission member 7 rYr that engages with the transmission member core. It is transmitted to λ2. As a result, both edges of the front wall of the window glass are window frames! OO leading edge structure jOf and trailing edge structure jOrK
It becomes a jin that is guided and ascends or descends.

Then, the window glass 2 is raised and its upper edge becomes the window frame! When the upper edge of the window glass is fitted to the upper edge of the window glass, the lifting of the window glass is stopped.

Then, the driving force is transferred to the pair of O transmission member cores in which the engaging portions II and 74 are engaged with each other, and the window glass JP

an engagement groove II of the transmission member 2t in which t, ij, and ij engage;
31 and 1-t- are appropriately inclined so as to rise as they go from the rear edge side to the front edge side of the window glass 29. Therefore, when the window glass λ is pushed upward, that is, from the transmission member core to the transmission member 1 in FIG. When the driving force in the direction is transmitted, the transmission member is ! In terms of the relative relationship with the transmission member core while receiving the pressing force in the direction, the engaging protrusion 3! And it tries to move in the U direction in FIG. 2 along the inclination direction of the engagement groove 31. As a result, the window pane 2 rises at a foreshadowing line where the trailing edge metal edge slides into contact with the trailing edge structure of the window frame 9, and therefore, the window glass 2 moves counterclockwise as shown in FIG. There is no fear that it will rotate, and the window frame! It is smoothly guided by O and raised.

Also, on the contrary, window glass λ? When the transmission member 1 is pushed downward, the transmission member 1 tends to move in the U' direction 111 in the figure in relation to the transmission member core, unless gravity is taken into consideration. The glass λ2 is prevented from swinging in the counter-hour lp direction at the Pal.

Therefore, the window glass λ does not rotate even during its descent, and is smoothly guided by the window 7 and 5 10 and lowered. In this manner, in both cases of being raised and lowered, the window pane is smoothly guided by the window 7 without being swung. Therefore, as in the conventional elevating device shown in Fig. 2, the upper end of the front edge of the window glass λ2 is brought into contact with the window frame 5j OK point when receiving a rotational moment in the counterclockwise direction 9 in the figure. The driving force is concentrated at a point and the window glass λ? There is no fear that the movement will be a little more than 90%. Therefore, it is possible to move the window glass 2 up and down extremely smoothly, and the operability is extremely improved.As in the above embodiment, the mutual %/hK of the pair of transmission members λ7 and 2t is 3 engaging protrusions on each side of the bird II,!
! and engagement 111131. It, jet-forms, seventy engagements, three! , 3! , 31 and the engagement groove it, it.

31 and 1, and the driving force is transmitted to the window glass -25' by the pair of transmission member core and coil IK, the thickness direction ( 2 directions in Fig. 1)K interval t1 engaging protrusion 31S It, 3! o9! By setting the output amount to an appropriate value, you can adjust the window glass, door frame, and window frame! 0 in the thickness direction can be absorbed by the distance IK.

Therefore, even if there is a deviation in the positional relationship between the window glass 22, the door frame 2, and the window frame 10 due to dimensional error #, there is a risk that the smooth vertical movement of the window glass 2 will be hindered by the deviation. There is no glazing, and the second window glass is the window frame! As mentioned above, in the vehicle window glass elevating device of the present invention, one of the pair of transmission members is connected to the drive cable body. The other side is fixed to the window glass, and one transmission member is formed with an engagement protrusion, and the other transmission member is formed with an engagement groove, and the engagement protrusion and the engagement groove are respectively formed. It is sloped so that it rises as it goes from the edge or side guided by the glass guide of the glass guide to the opposite side, and
The engagement protrusion and the engagement groove Htx are engaged so that they can slide freely, and the driving force is transmitted from the drive cable body to the above-mentioned pair of P transmission member cores and to the window glass by elevating and lowering it. It is being done. Follow me, the window glass is on top! #Whether it is raised or lowered, at least one of its front and rear edges, the gold edge of the O edge, is slid into contact with the glass guide and guided in that state. Therefore, it does not receive @dynamic moment like a conventional lifting device.

For example, if the upper end of the front edge of the window glass comes into point contact with the Wj array 5, there is a risk that the driving force will be concentrated at the contact point and the window glass will move in a stiff or stiff manner. If the window glass could be moved up and down very smoothly, it would be extremely easy to operate. For example, when trying to raise and lower a window glass using a screen, there is no fear that the screen will be overloaded and cause a burnout noise.

FIG. 70 and FIG. 1/FIG. 1 show a modification of the wheel window glass elevating device of the present invention in which the transmission member is directly fixed to the window glass. Fitting protrusions /, j/ are integrally formed on both ends of the transmission member core ra, and the fitting protrusions /, j/ protrude 98 times to the opposite side of the engaging part, and the fitting protrusions 11 and 1 are the 1st iHr1.

The window glass 22G and the transmission member 2J are engaged with the lower edge of P6.
A deviation in the θ direction between K and K in FIG. 10 is prevented.

Incidentally, in any of the above-described embodiments of the present invention, a drive chain in which a spherical engaging element is made of a flexible one-piece bead shape is used as the drive cable body.
This KWk is not limited to 4, but other types, such as a flexible synthetic resin tape, may be used as a drive cable body.
