Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window regulator for raising and lowering a windshield of an automobile, and more particularly to a wire-type window regulator.

Conventionally, this type of window regulator 1 is manufactured by sliding a glass bracket 1 driven by a wire 3 along a side rail fixed to a door panel or a vehicle body panel outside the figure 1, as shown in FIG. , the window glass 3f attached to the glass bracket can be raised and lowered. The wire 3 is bent and guided in one direction by pulleys J and 6a as guide members provided at both ends of the guide rail, and both ends of the wire 3 are connected to a drum as an actuator. VC is locked,
The wire 3 is driven by rotating the drum 7. By the way, the wire 3
is a bracket to which the pulleys a and 6a are attached to maintain tension.

An outer tube 1 fitted around the outer periphery of the wire 3 is provided between the pace plate holder and the pace plate holder to which the drum 7 is attached.
0 and 10a are arranged. ii, ii a are the outer tubes 10, 10 a f brackets,
This is a spring that biases in the a direction.

However, in such a conventional window regulator, a pulley t is used as an id member.

Since Aai was used, in order to assemble the wire 3 under tension, it was necessary to ride over the side wall of the goo IJ t, 6a and lock it in the groove. As shown in FIG. A groove 13 is formed by the wire, and when the wire 3 is assembled, the tensioned wire 3 is further stretched while the side wall 13 is inserted.

/2a from the entire outside to the inside of the groove 13. Therefore, assembly at this time becomes extremely difficult and workability deteriorates.

Furthermore, since the pulley 7+4a is added via the brackets g and a that are fixed to both ends of the guide rail λ, the number of parts increases due to the brackets g and a, and the entire i bracket ♂♂a is The extra work of fixing it to the guide rail λ becomes necessary.

Further, both ends of the outer tubes 10 and 10a need to be supported by the bracket, the groove and the base plate, respectively.

If there are brackets za, zaaK, there are bent portions lda+ at the ends of the brackets g, ga, as shown in FIGS. 3 and 4.
1'Aak is formed, and one end of the outer tube 10, 10a is supported by the bent portion /II, /daa. Therefore, it becomes necessary to perform an operation to form the bent portion lda+/4'ak in the bracket groove a.

Furthermore, since one of the pair of outer tubes 10 and 10a (upper tube in this conventional example) can be supported before the wire J is tensioned, as shown in FIG. A fitting hole lj is formed in the bend i11/4' of the upper bracket.

It is fitted and supported in this fitting hole 15 via a collar 16. 17 is fixed to one end of the acta tube IO,
This is a locking ring that is locked to the collar 16. On the other hand, since the other outer tube 10a (lower in this conventional example) needs to be supported after the wire 3 is tensioned, one end is attached to the bent part l of the lower bracket ga as shown in FIG. A U-shaped notch 15 a f is formed in which the outer tube 10 a is opened, and one end of the outer tube 10 a is fixed to this notch g / ? Fit together with a,
In order to prevent the locking IJt/7a from being pulled out from the open side of the notch isa, the upper side of the locking ring/7a is fixed by a fixing metal fitting 18 fixed to the bracket a. In order to support one end of the outer tubes 10 and 10a on the brackets ♂ and ra in this way, the collar/6.
Since the locking rings /7, /7a and the fixing metal fittings IT are required, the number of parts increases in these parts as well, and the workability for assembling these parts deteriorates.

As mentioned above, in conventional window regulators, the boos 96, 6a are used as guide members, which deteriorates the ease of assembly and increases the number of parts, which increases the cost of the product. There was a problem with the connection.

In view of such conventional problems, the present invention has a guide member that has a function of bending the wire in the direction of the entire actuator and a function of fully supporting one end of the outer tube. The wire fitting groove for fully fitting and fixing the wire in between is fully utilized, and a part of the side wall of the boob function part is cut out at the intersection with the wire, reducing the number of parts. It is an object of the present invention to provide a window regulator that completely facilitates workability.

Finally, the lower outer tube 10a'f is strongly pulled in the direction of the drum 7 to fit one end of the outer tube 10a (in the direction of the guide member 20a) into the fitting part la.

Note that the fitting part j formed in the guide member m at the upper end is formed in a hole shape, whereas the fitting part Ja formed in the guide member 20a at the lower end part is open at the upper side. The outer tube 10a is easily fitted into the outer tube 10a when the wire 3 is under tension. It is of course possible to assemble the wire 3 in the reverse order from the guide member 1a at the lower end to the guide member 20 at the upper end.

When the windshield 5tl is raised and lowered, the wire 3 is moved to the guide member 20 by rotating the drum 7.
, 20a are driven while sliding in the guide grooves 2/, 2/a, and the guide bracket 20a moves on the guide rail λ. Therefore.

The kite groove 2/, J/a is the conventional boo I
It performs the function of 77°Aa, and the guide members 2o and 2°a serve as the conventional bracket grooves 1ga. *Ja is the conventional bending part, /9a, collar /6 x U locking ring /7. /7a functions.

Incidentally, the fitting part ja formed by opening the upper part of the guide member 20a may be provided with a lid member that covers the upper opening part in order to prevent the outer tube from falling off after the outer tube 7a is attached. , by doing this the outer tube/
(It is possible to reliably prevent the lea from falling off.

By the way, the wire 3 in the tension state is connected to the kite member J/
When hanging the guide groove 2/a, the wire hanging part J'a may be provided by notching the side wall 2Jai of the guide groove 2/a as described above. Since the wire 3t'' is formed approximately in the tangential direction of the kite 2/a, when taking the wire 3t'' outward from the kite 2/a, the length of the wire 3 is smaller than in the case where the wire 3t exceeds the entire height of the side wall 2ja. The tensile force can be reduced.The wire hanging parts 2'l, 2'
The open side of l a should be widened.

The work of hanging the wire 3 can be further facilitated.

As explained above, the present invention includes a kite rail for slidably attaching a crow bracket that can be attached to a wind crow, and an intermediate portion disposed along the length of the guide rail, and , a wire whose both ends are connected to an actuator and driven by the actuator; and a glass which is fixed to the guide rail installation portion of the wire and is slidably attached to the guide rail. The windshield is equipped with a bracket and a guide member provided at both ends of the guide rail to guide the wire in the direction of the actuator, and when the wire is driven by the actuator, the window glass attached to the glass bracket is raised and lowered. In the window regulator, the guide member includes a guide groove that smoothly guides the wire toward the actuator, a wire fitting groove that extends from the actuator side in a tangential direction of the guide groove, and a wire fitting groove that extends from the actuator side in a tangential direction of the guide groove. At the intersection of the groove and the guide groove, a wire hanging part is formed by cutting out the side wall of the guide groove in a substantially tangential direction of the guide groove continuously from the fitting groove to the outer periphery of the side wall, and an actuator side of the fitting groove. Since the fitting part for fitting and locking one end part of the outer tube that houses the wire is formed integrally with the end part, when the wire in a tensioned state is hung on the guide member, S. It is necessary for the wire to cross over the side wall of the guide groove, but in this case, by inserting the wire into the wire hanging part formed by cutting out the side wall, the wire hanging part can be inserted into the guide groove. The tangential configuration allows the wire to ride over the side wall in substantially the shortest distance. Therefore, at this time, the tension force on the stretched wire can be reduced and the wire hanging operation can be made easier. Furthermore, since the guide member itself can be attached to the guide rail or the panel to which the guide rail is fixed, there is no need for a bracket as in the prior art. In addition, by fitting the inner wire into the wire fitting groove, the wire is stably fixed.
Since one end of the outer tube that is fitted to the outer circumference of the wire is fitted to the fitting part along the fixed wire, the workability of attaching the outer tube is dramatically improved, and in addition, the outer tube One end of the tube need only be fitted into the fitting part, and there is no need for a bent part of the bracket, a locking collar, etc., as in the conventional case, and it can be combined with the unnecessary bracket. This has the excellent effect of achieving a significant reduction in the number of parts, simplifying the assembly work, and reducing the cost of the product.
