Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a window regulator for opening and closing a window glass of a window of a vehicle or the like, and more particularly to a window regulator configured to open and close a window glass using a wire.
[0002]
[Prior art]
The so-called “wire-type” window regulator that opens and closes the window glass of a vehicle or the like by moving the support body supporting the window glass up and down using a wire is a link or pantograph type. Compared with the advantage that the space in the door can be used for other purposes, it has been frequently used in recent years.
[0003]
As this wire type window regulator, for example, Patent Document 1 or Patent Document 2 has been proposed. In these conventional window regulators, a support body supporting a window glass is slid on a guide rail in the vertical direction. The support is supported freely, and the support is moved up and down on the guide rail by a wire. And a "pulley" is attached to the upper and lower ends of this guide rail, and the wire is guided by this pulley.
[0004]
[Patent Document 1]
No. 5-15029 (1st page, 2nd page, and Fig. 6)
[0005]
[Patent Document 2]
No. 6-3952 (Pages 1, 2, 4 and 5) Therefore, the "pulley" in the conventional window regulator must rotate while guiding the wire. Of course, in order to do so, the "axis" is necessary. Since the force from the drive device that drives the wire is applied to this pivot through the pulley, failure will occur unless bearings are provided or both ends of the pivot are processed. It becomes easy. In other words, a conventional window regulator that employs a “pulley” requires complicated processing and countermeasures particularly in the pulley portion.
[0006]
In addition, this type of window regulator is completely housed in the door, but rainwater easily enters the door as the window glass enters and exits. "Is likely to occur in each component of the window regulator.
[0007]
In particular, in the window regulator of Patent Document 2, the pulley must be “cantilevered” as shown in FIG. 4 of the document, and the pulley is directly supported on the inner panel of the door. Therefore, it is considered that the pivot and its periphery are easily corroded. For this reason, if the direction of the pivot is changed or the pivot is removed due to corrosion of the inner panel or the like, the wire cannot be guided by the pulley, and the window regulator itself may be broken.
[0008]
Therefore, the present inventors have completed the present invention as a result of various studies on how to improve the conventional wire type window regulator.
[0009]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described actual situation in this type of wire type window regulator, and a problem to be solved is to make it difficult for failure to occur and to have excellent durability.
[0010]
That is, first, an object of the invention according to claim 1 is to provide a wind regulator that is easy to manufacture and excellent in durability by integrating a portion that guides a wire and a portion that is fixed to an inner panel. It is to be provided by a simple structure.
[0011]
Further, it is an object of the invention according to claim 1 is also to provide a window regulator which can prevent the occurrence of "Densawa" as much as possible.
[0012]
The object of the invention according to claim 2 is that the same object as the invention according to claim 1 can be achieved, and the force from the wire side is directly applied to the inner panel side, An object of the present invention is to provide a window regulator that can further enhance the overall durability.
[0013]
[Means for Solving the Problems]
In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the embodiments described later.
“The vertical guide rail 10 attached to the inner panel 200 side of the door, the glass support 20 that slides on the guide rail 10, and the wire 30 that transmits the driving force of the driving device 40 to the glass support 20. A window regulator 100 that opens and closes the window glass 210 supported by the glass support 20 by moving the glass support 20 up and down,
For the upper and lower ends of the guide rails 10, fitted with a rigid block 50a, and a sliding block 50b integrally provided with a protrusion 53 which would be interposed between the guide rail 10 with the rigid block 50a Attach the integrated support member 50,
By fixing the rigid blocks 50a to the inner panel 200, to fix the upper and lower end portions of the guide rail 10 to the inner panel 200, the wire 30 by the sliding surface 52 of the sliding block 50b fitted to the rigid blocks 50a Wind regulator 100 characterized by being guided "
It is.
[0014]
That is, in the window regulator 100 according to the first aspect of the present invention, in particular, the support members 50 in which the rigid block 50 a and the sliding block 50 b are fitted and integrated are attached to the upper and lower ends of the guide rail 10. In this case, only the rigid block 50a constituting each of the upper and lower support members 50 is fixed to the inner panel 200 using an attachment hole 51 formed at the center or the like, for example, as shown in FIG. It is a thing. Thus, the upper and lower ends of the guide rail 10 are fixed to the inner panel 200, and the sliding block 50 b fitted and integrated with each rigid block 50 a guides the wire 30 by the sliding surface 52. It will be.
[0015]
In other words, in the window regulator 100 according to the first aspect, each of the support members 50 to be attached to the upper and lower end portions of the guide rail 10 is literally formed into a block shape with a material having high rigidity such as aluminum or cast iron. The sliding block 50b formed to have a certain degree of rigidity and sliding characteristics with a synthetic resin or the like is integrated with the means 50a simply by means of fitting or combination.
[0016]
Each rigid block 50a is fitted and attached to the upper and lower ends of the guide rail 10 using, for example, a rail fitting groove 56 as shown in FIG. 9 (C) and FIG. 14 (B). Then, it is fixed to the inner panel 200 side by bolts or the like through a mounting hole 51 formed at the approximate center thereof. Of course, the rigid block 50a may be made of die-cast metal with the metal material as described above. Therefore, the necessary portion of the meat is integrated with ribs to literally “block” it.
[0017]
On the other hand, as shown in FIG. 3, each sliding block 50b is integrated with each rigid block 50a by means of fitting or the like, with its sliding surface 52 facing outward. Only the wire 30 is received and slid by the sliding surface 52 facing outward. In order to make the sliding of the wire 30 by the sliding surface 52 smooth, the sliding surface 52 of the sliding block 50b has an arc shape as shown in FIG. Since the members are in a positional relationship as shown in FIG. 3, a substantially ¼ arc is sufficient for the portion where the slidably contacts. As shown in FIG. 9E, the sliding block 50b is integrally formed with an engaging portion 55, and the sliding portion 50b is rigid. When fitted to the block 50a, it engages with a recessed portion or the like on the rigid block 50a side, thereby further ensuring integration with the rigid block 50a.
[0018]
In the window regulator 100 configured as described above, the support members 50 provided at the upper and lower ends of the guide rail 10 are integrated by fitting the rigid block 50a and the sliding block 50b. Since the wires 30 are supported by the rigid block 50a by the rigid block 50a and the sliding of the wire 30 with respect to the support member 50 is performed by the sliding block 50b, so-called division of labor is performed, so that each rigid block 50a and sliding block 50b. The durability of is increasing. That is, each sliding block 50b is fitted to the rigid block 50a and does not require rotation like the “pulley” in the prior art, so that the inner panel 200 is attached to a predetermined position. No pivot or bearing is required. Of course, the sliding contact of the wire 30 with respect to the support member 50 is sufficiently performed because the sliding surface 52 is formed only at the necessary portion of the sliding block 50b where the wire 30 contacts.
[0019]
In addition, if the guide rail 10 is corroded by rainwater or electric contact is generated between the guide rail 10 and the support member 50, there is a problem in fitting and fixing of the support members 50 to the guide rail 10. Even so, since the rigid block 50 a of each support member 50 is directly fixed to the inner panel 200 through the mounting hole 51, no change occurs in the guide of the wire 30 by each support member 50. The basic function of the window regulator 100 for moving the glass support 20 up and down is maintained as it is.
[0020]
Therefore, the window regulator 100 according to the first aspect of the present invention is very easy to manufacture because the supporting members 50 to be attached to the upper and lower ends of the guide rail 10 are constituted by the rigid block 50a and the sliding block 50b. In addition, since there are no rotating parts, the overall durability is high, and even if the guide rail 10 is corroded or an electrical contact occurs between the guide rail 10 and the support member 50, It is something that can fully demonstrate its original function.
[0021]
Further, in the window regulator 100 according to the first aspect of the present invention , when the support member 50 is attached to the end of the guide rail 10, the protruding portion 53 that is interposed between the guide rail 10 and the rigid block 50a. the Ru der made by forming integrally a part of the sliding block 50b.
[0022]
That is, in the window regulator 100 of the claims 1, part of the slide block 50b constituting the respective support member 50, for example, as shown in FIG. 9 (d) and (e), the protrusion 53 For example, as shown in FIG. 13, the protrusion 53 is formed integrally between the guide rail 10 and the rigid block 50a when the support member 50 is attached to the end of the guide rail 10. It will be interposed.
[0023]
If the protruding portion 53 in the sliding block 50b is interposed between the guide rail 10 and the rigid block 50a, the probability that electric contact is generated between the metal constituting the guide rail 10 and the support member 50 is increased. Will be reduced. Of course, each support member 50 is fixed to the inner panel 200 side by the rigid block 50a constituting the support member 50, so that the protruding portion 53 is interposed between the guide rail 10 and the rigid block 50a. Even if it sees as the whole supporting member 50, there is no influence on fixation to the inner panel 200 and support of the wire 30 here.
[0024]
Therefore, the window regulator 100 according to the first aspect of the present invention is less durable due to rainwater or the like soaking into the door, and has high durability.
[0025]
Furthermore, in order to solve the above-mentioned problem, the means taken by the invention according to claim 2 relates to the window regulator 100 according to claim 1 ,
“The tube support portion 54 that directly supports the end portion of the outer tube 31 of the wire 30 is provided in a part of the rigid block 50a.”
It is.
[0026]
That is, in the window regulator 100 according to the second aspect , the wires 30 are supported by the support members 50 by the rigid block 50a of the members constituting the support member 50, and the slide block 50b simply slides the wire 30. Alternatively, it is used for sliding contact. In other words, in each support member 50, the force applied through the wire 30 is mainly borne by the rigid block 50a, and the sliding block 50b fitted to the rigid block 50a performs only good sliding or sliding contact of the wire 30. Thus, the sliding contact of the wire 30 is improved while increasing the overall rigidity.
[0027]
Therefore, the window regulator 100 according to the second aspect of the invention not only exhibits the same function as that of the first aspect but also allows the force from the wire 30 side to be directly applied to the inner panel 200 side. Is a further improvement.
And the means taken by the invention according to claim 3 is the window regulator 100 according to either claim 1 or claim 2,
“The rigid block 50a is made of metal and the sliding block 50b is made of synthetic resin.”
It is.
[0028]
