Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a mechanism for vertically moving a window glass holder for an automobile, between the bracket of the window glass holder fixed to a flexible shaft and the outer tube into which the flexible shaft is loosely inserted. The present invention relates to a structure of a bracket part of a vehicle window glass holder, which is intended to prevent rattling of the window glass holder.

Conventionally known mechanisms for moving up and down automobile window glass include, for example, as shown in FIG. A glass holding odor d is bonded to a flexible shaft c for the purpose, and an outer tube e into which the flexible shaft c is loosely inserted and holds the flexible shaft c movably in the axial direction. However, it is necessary to provide a sufficient gap f between the inner diameter of the outer tube e and the outer diameter of the flexible shaft c in this type of window glass up/down operation mechanism.

This is because, as shown in the figure, the flexible shaft c and the outer tube e must be bent as appropriate before use, so if the gap f between the outer tube and the flexible shaft is small, the inner surface of the outer tube e at the bent portion may This is because the reinforcement pressure with the outer surface of the flexible shaft c becomes large, and the movement of the flexible shaft c in the koji direction cannot be performed smoothly. For this reason, the design is such that a sufficient gap f is formed between the inner surface of the outer tube e and the outer surface of the flexible shaft c, but since this gap f is large, the flexible shaft c The gap between the outer surface d' of the cylinder part of the holding odor d to be inserted and fixed and the inner surface of the outer tube e also becomes large, and this causes the inconvenience that the above-mentioned backlash occurs between the outer surface d of the cylinder part and the outer tube. there were.

The present invention has been made to solve this problem, and in a vertical movement mechanism that uses a flexible shaft to move an automobile window glass up and down, the outside of the flexible shaft fixing part of the glass holder bracket and the flexible shaft are connected to each other. A cylindrical sleeve is interposed between the guiding outer inner surface and the flexible shaft to prevent play between the flexible shaft and the outer tube. The present invention will be described in the third section below.
The embodiment will be explained in detail based on the embodiment shown in FIGS.

Reference numeral 1 denotes a vehicle glass holder, and a bracket 2 of the holder is attached to the lower part of the glass holder 1.

The bracket 2 of this holder includes a holder receiving part 21 with a U-shaped side surface that grips and holds the lower part of the holder 1, and a dispensing part 22 formed from the front side of the holder receiving part 21 in a direction perpendicular to the front surface. A cylindrical flexible shaft fixing part 23, which is formed at the end of this dispensing part and extends in the vertical direction, is integrally formed of, for example, a metal material. This cylindrical flexible shaft fixing part 2
A presser piece 25 is formed at both upper and lower entrances of the holder 3, and is divided by a notch 24. By caulking the presser piece 25, the bracket 2 of the holder is fixed to a flexible shaft 3, which will be described later. The means for fixing this holder to the flexible shaft 3 of the bracket 2 is not limited to this, and other suitable fixing means may be employed. Reference numeral 3 denotes a flexible shaft formed by winding a wire into a coil shape. This flexible shaft 3 is loosely inserted into the outer tube 4, and when the flexible shaft 3 is moved in the axial direction with a handle (not shown), the flexible shaft 3 The holder 1 can be moved up and down as the shaft moves.

Reference numeral 5 denotes a sleeve which is the main point of the present invention, and this sleeve 5 has a slit 51 in the generatrix direction and is made of a material that is flexible.

Further, stoppers 52 are formed protruding from both ends of the slit 51 of the sleeve 5, and the sleeve 5 is interposed between the outer surface of the flexible shaft fixing part 23 and the inner surface of the outer tube 4. It is something that exists. Furthermore, to specifically describe the positional relationship (combination) of the bracket 2, flexible shaft 3, sleeve 5, and outer tube 4 of the holder,
First, fix the flexible shaft fixing part 2 of the bracket 2 of the holder.
The flexible shaft 3 is inserted into the cylindrical portion of the holder 3, and the flexible shaft 3 is fixed to the bracket 2 of the holder by applying the presser piece 25. Next, the sleeve 5 is placed on the outer side of the flexible shaft fixing part 23 of the bracket 2 of the holder. When applying the sleeve 5, the sleeve 5 is inserted into the slit 51 from the end of the sleeve 5. 22, and the flexible shaft fixing part 23 is placed in the sleeve 5. Next, when the sleeve 5 is slightly rotated, the stoppers 52 provided on the sleeve 5 come into contact with both upper and lower ends of the dispensing part 22 of the bracket 2 of the holder, and the sleeve 5 is attached to the flexible shaft fixing part 23. Next, when the flexible shaft fixing part 23 to which the sleeve 5 is attached is inserted into the outer tube 4 together with the flexible shaft 3, the outer side of the stopper 52 of the sleeve 5 and the disseminated part 22 of the bracket 2 of the holder are connected to the outer tube. By moving the flexible shaft 3 in all axial directions, the bracket 2 of the holder is moved together with the sleeve 5 within the outer tube 4 as the flexible shaft 3 moves. It is something. As described above, according to the present invention, the outer side of the flexible shaft fixing part 23 of the bracket 2 of the holder,
Since the sleeve 5 is interposed between the inside of the outer tube 4, the action of the sleeve 5 prevents play between the flexible shaft fixing portion 23 and the outer tube 4. , the placket 2 of the holder can be guided by the outer tube 4 and slid smoothly. In addition, in order to attach the sleeve 5 to the bracket 2 of the holder, the two are engaged by a joining action using the slit 51 of the sleeve 5, so there is no need to prepare fixing fittings etc. in advance. Therefore, it is possible to provide a bracket structure for a vehicle window glass holder that is easy to assemble, has a small number of parts, and is inexpensive.
