Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a windshield elevating device for an automobile, and more particularly to measures to prevent rotational rattling of the windshield.

Various types of windshield lifting devices have been proposed for automobiles in the past.Among these, the windshield is a device that is relatively light in overall weight and can help reduce the weight of automobiles. A one-point support system is known in which the holder is supported at a single point at its lower end.

That is, this one-point support type, for example, includes a guide block fixed to the lower end of the window glass at the approximate center, and a door panel attached to the guide block.
and a guide tube whose cross section is partially open and which guides the guide block in the up-and-down direction (vertical direction) of the window glass; A cable member connected to the guide block through the open portion and a driving means for feeding or pulling the cable member are provided, and the cable member is moved by operation of the driving means to raise and lower the window glass. A cable-driven type, or a pinion gear that is pivotally supported on a base fixed to the door panel, a sector gear that meshes with the pinion gear, and a pinion gear that is swingably supported on the base and whose lower end is fixed to the sector gear. , a regulator arm whose upper end slidably engages with a regulator guide integrated with the holder when the lower end of the window glass is held, and the regulator arm is swung by rotational drive of a pinion gear. A typical example is a single-arm type that allows the window glass to be raised and lowered.

However, in this type of single-point support system, the windshield is supported at one point, so if it is applied to a front window that does not have a guiding door sash in front of the windshield, the windshield will be susceptible to external forces such as vibrations and static during elevation. Due to this phenomenon (stuck phenomenon), there was a problem in that the door sill was tilted forward without the door sill, and rotation play was likely to occur.

For this reason, in order to prevent such rotational play of the single-point support type window glass, as disclosed in, for example, Japanese Utility Model Publication No. 48-33375,
A window glass lifting device has been proposed in which a slider that engages with the rear vertical portion of a door sash is superimposed on the window glass surface and fixed to the upper rear end of the window glass, and the slider locks and guides the window glass. ing.

However, in this proposal, since the slider overlaps the window glass surface, the wall thickness of the overlapped part increases, and as a result, the opening degree of the opening in the rear vertical part of the door sash increases. There was a problem that the door sash required a special one.

In view of this, the present invention has been developed by cutting out the rear upper end corner of the window glass to form a notch, and inserting a synthetic resin material into the notch for raising and lowering the window glass up and down along the door sash. Attach the sliding block, and
A base having the same thickness as the window glass, a mounting portion extending from the base to both sides of the window so as to sandwich the window glass, and a mounting portion provided in a portion of the base located within the sash, in the thickness direction of the window glass. The guide part protrudes from the door sash and engages with the tip of the lip of the launch channel inserted into the sash, so there is no need to widen the opening of the opening of the door sash. Enables the use of door sashes,
Therefore, it is an object of the present invention to provide a windshield elevating device for an automobile which can prevent the windshield from rotating loosely even though it has a simple structure.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

In Figure 1, 1 is the front door of a car;
2 is a window formed by a door frame 3 on the upper part of the front door 1; 4 is a substantially trapezoidal window glass fitted into the window 2;
The front end of the window glass 4 is slidably fitted into a guide member 5 fixed to the door panel 1a of the door 1, and the rear end is slidably fitted into the rear vertical part 3a of the door sash 3. The window 2 is opened and closed by moving the glass 4 up and down while being guided by the guide member 5 and the rear vertical portion 3a of the door sash 3.

An elevating block 6 is fixed to approximately the center of the lower end of the window glass 4, and the elevating block 6 is connected to a cable guide 7 attached to the door panel 1a arranged in the same direction as the elevating direction of the window glass 4.
It is slidably supported on the outside. The cable guide 7 is formed into a pipe shape with a part of its cross section continuously open, and inside the cable guide 7 is a ball chain-shaped cable member 10 that engages with a sprocket wheel 9 that is rotationally driven by a motor 8. The upper end of the cable member 10 is connected to the lifting block 6 through the open portion of the cable guide 7, and the cable member 10 is inserted into the cable guide 7 by forward and reverse rotation of the motor 8. A power window mechanism is constructed in which the lift block 6 connected to the cable member 10 is raised and lowered while being guided by the cable guide 7, and the window glass 4 is opened and closed.

Further, a triangular notch 11 is formed at the rear upper end corner of the window glass 4 by cutting the corner diagonally, and the window glass 4 is inserted into the rear upper corner of the door sash 3. A sliding block 12 made of synthetic resin is attached to guide the vertical movement up and down along the side vertical portion 3a. The sliding block 12
As shown in enlarged detail in FIG. 3 and FIG. 3, a triangular plate-shaped base 12a is formed to have the same thickness as the window glass 4 and the same shape as the cut-out portion of the corner portion of the window glass 4; Base 12a
A pair of plate-shaped attachment portions 12b, 12b extend forward from the front end of the window glass 4 to both sides of the window glass 4 so as to sandwich the window glass 4, and a portion located within the rear vertical portion 3a of the door sash 3 at the rear end of the base 12a. Lips 13a, 13a of the launch channel 13 are provided and protrude from both sides in the thickness direction of the window glass 4, and are fitted into the door sash 3.
It consists of a pair of triangular block-shaped guide parts 12c, 12c that engage with the tip. In addition, protrusions 14 facing each other are formed on the inner surface (contact surface with the window glass 4) of each of the mounting portions 12b. The sliding block 12 is fixed to the window glass 4 by fitting from both sides.

Therefore, in the above embodiment, the window glass 4 is moved to the position of the lifting block 6 at the lower end and the position of the sliding block 12 (guide section 1) at the rear upper corner.
2c and 12c), so that even if an external force such as vibration is applied to the window glass 4 or a stuck phenomenon occurs when the window glass 4 is raised or lowered, The window glass 4 does not tilt forward about its lower support point (elevating block 6), and rotational play of the window glass 4 can be reliably prevented.

In that case, the portion of the sliding block 12 corresponding to the front end open portion of the rear vertical portion 3a of the door sash 3 has a base 12a having the same thickness as the window glass 4.
Therefore, the rear vertical portion 3a of the door sash 3
The opening size of the opening part may be a size corresponding to the plate thickness of the window glass 4, and therefore, a normal door frame 3 can be used, so that the door frame 3 can be manufactured at a low cost.

Furthermore, since the sliding block 12 is made of resin, when attaching the sliding block 12 to the rear upper end corner of the window glass 4, both mounting portions 12b, 12b are expanded and the protrusions 14, 14 are attached.
All you have to do is insert the window glass 4 between them, slide the whole thing as it is, and fit the protrusions 14, 14 into the mounting holes 15 of the window glass 4.
Installation work can be done with one touch.

In the above embodiment, the sliding block 12 has two guide portions 12 protruding from both sides of the base portion 12a.
c and 12c are provided, but it is also possible to have one guide part and make it protrude only to one side of the base, and the same effect as in the above embodiment can be achieved.

Further, in the above embodiment, the case where the present invention was applied to a cable-driven type power window regulator was described, but it goes without saying that the present invention can also be applied to a single-arm type wind regulator. .

Furthermore, although the above embodiment is applied to the front door 1 of an automobile, the present invention can also be applied to various automobile doors that do not have a sash on either side. .

As described above, according to the automobile window glass elevating device of the present invention, a base portion having the same thickness as the window glass, a mounting portion for holding the window glass, and a launch channel of the door sash are arranged at the rear upper end corner of the window glass. A sliding block consisting of a guide part that engages with the tip of the lip is attached, and the sliding block guides the window glass up and down along the door sash, making it possible to use a regular door sash. However, even with a simple structure, it is possible to reliably prevent rotational play when the window glass is raised or lowered.

Furthermore, since the sliding block is made of synthetic resin, the sliding block can be attached to the window glass with a single touch, and the ease of mounting the sliding block can be improved.
