[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention relates to a mechanism for connecting a wire and a slider in a window regulator that opens and closes a window glass for a door of an automobile or the like.

(Prior Art) One of the above-mentioned wind regulators is a wire-driven type. That is, the wire is driven by a drive device and a slider connected to the wire is moved along a rail to raise and lower the window glass.

Conventionally, the wire and the slider were connected by, for example, a mechanism shown in FIG. 11.
That is, the reference numeral 2a' in the figure indicates a wire, and a cylindrical connecting member 40' is fixed to this wire 2a'. This connecting member 40' is previously formed into a cylindrical shape, and is fixed by caulking after being inserted into the wire 2a'. On the other hand, the slider 8' is formed with an insertion part 50', and this insertion part 50' has locking walls 54', 54' for locking at least both ends of the connecting member 40', and the locking wall part 5.

5' and 55'. This insertion part 5
By inserting the connecting member 40' into the
The wire 2a' and the slider 8' are connected to each other.

A support member (not shown) is further attached to the insertion portion 50', and this support member prevents the connecting member 40' from falling off.

(Problems to be Solved by the Invention) However, in such a conventional connection mechanism, since the insertion portion 50' is formed in the slider 8', the structure of the slider 8' becomes complicated and However, it had the disadvantage of high manufacturing costs.

Also, depending on how the support member is attached,
The connecting member 40' may come off from the insertion portion 50', and the supporting member must be securely fixed by welding or the like, making the connecting work complicated.

Structure of the invention (means for solving the problem) This invention was made to solve the above problem, and its gist is to drive a wire and move a slider connected to the wire along the rail. In the window regulator, which opens and closes the window glass by moving the slider, the slider includes an insertion hole formed in the slider, a connecting member fixed to the wire and inserted into the insertion hole, and supporting the connecting member. the connecting member has locking grooves on two end faces substantially perpendicular to the wire, and the insertion hole has a large hole portion into which the connecting member is inserted, and a supporting member for locking the connecting member. The support member has a pair of elastic locking portions, and by inserting and locking the elastic locking portions into the insertion hole, the small hole portion is connected to the groove. A connecting mechanism for a wire and a slider in a wind regulator is characterized in that it supports a connecting member locked to a portion thereof.

(Example) Hereinafter, an example of this invention will be shown in Figures 1 to 10.
The explanation will be based on the drawings up to the figure.

FIG. 1 shows an overall outline of a window regulator 1 installed in a door of an automobile (not shown). Reference numeral 2a in the figure indicates a ring-shaped wire. This wire 2
a is driven by the rotation of a rotating drum 4 provided in a drive device 3. On the other hand, reference numeral 5 indicates a main rail, and support plates 6a and 6b are attached to the upper and lower ends of this main rail 5. A fixed pulley 7a and a guide 7b are provided on the driving device 3 side of the support plates 6a and 6b, respectively, and the wire 2a is stretched between the fixed pulley 7a and the guide 7b. A slider 8 is supported on the main rail 5 via upper and lower rollers 9 so as to be freely movable. The slider 8 is connected to a wire 2a via a connection mechanism to be described later, and is moved up and down along the main rail 5 by driving the wire 2a. Furthermore, window glasses (not shown) are attached to attachment holes 8a and 8b on both sides of the slider 8 via predetermined means.

The main rail 5 is formed to be curved along the movement locus of the window glass. Further, a sub-rail 10 having a U-shaped cross section is attached to the main rail 5 on the opposite side of the drive device 3. A balance roller 11 which also serves as a movable pulley is provided within this sub-rail 10. A subwire 2b is suspended between the balance roller 11 and a fixed pulley 7c attached to the upper support plate 6a. One end of this sub-wire 2b is attached to the support plate 6a,
The other ends are each connected to the slider 8 via a connection mechanism that will be described later. The above balance roller 11
The upper and lower ends of the balance spring 12 are hooked to the center portion of the balance spring 12 and the mounting groove 7d of the lower support plate 6b. This balance spring 12 is a cylindrical tension coil spring and has a function as a balancer. The balance roller 11 is configured to descend within the sub-rail 10 as the slider 8 rises, and rise within the sub-rail 10 as the slider 8 descends. Further, the load of the window glass is supported by the balance spring 12.

Next, the connection mechanism 20 between the wire 2a and the slider 8 will be explained based on the drawings of FIGS. 2 to 10. This connection mechanism 20 is the gist of this invention, and includes an insertion hole 30 formed in the slider 8 and an insertion hole 30 fixed to the wire 2a.
0, and a resin support member 50 that supports this connection member 40. Each of the above members will be explained below.

The connecting member 40 is shown in FIGS. 2 and 3. This connecting member 40 has a plate shape, and its base 41 is
It is formed thicker than the tip portion 42. base 41
The outer surface is formed into an arc shape, and an insertion hole 43 for passing the wire 2a is bored in the center thereof. As shown in FIG. 10, the connecting member 40 and the wire 2a are fixed by inserting a predetermined position of the wire 2a into the insertion hole 43 and caulking the wire 2a. Tapers 43a are formed at both ends of the insertion hole 43 such that the diameter increases outwardly.
is formed. Since the slider 8 runs along the curved main rail 5, the wire 2a
Although the wire 2a is inclined with respect to the insertion hole 43, this inclination of the wire 2a is allowed by the taper 43a, and the wire 2a is prevented from being disconnected at the edges of both ends of the insertion hole 43. Further, the tip portion 42 is formed longer in the direction of the wire 2a than the base portion 41, and has two end surfaces 44, which are substantially perpendicular to the wire 2a.
44, locking grooves 45, 45 are formed, respectively.

The insertion hole 30 of the slider 8 is shown in FIG.
This insertion hole 30 has a large hole part 31, a small hole part 32, and a sub-small hole part 33. Each hole 31, 32,
33 is continuous, and its length in the direction of the wire 2a
Lc, Ld, and Le are decreasing in order. The length Lc of the large hole 31 is the length Lc of the tip 4 of the connecting member 40.
The length La between the two end surfaces 44, 44 is the same as or slightly longer than this. Further, the length Ld of the small hole portion 32 is approximately equal to the length Lb between the inner end surfaces of the locking grooves 45, 45 of the distal end portion 42.

The connecting member 40, which is caulked and fixed to the wire 2a at a predetermined position, is then connected to the slider 8. First, insert the tip 42 of the connecting member 40 through the large hole 31 of the insertion hole, and then insert the connecting member 40 into the large hole 31 of the insertion hole.

The support member 50 is shown in FIGS. 4 to 6.
This support member 50 has a U-shaped longitudinal section and has a pair of elastic locking portions 51 and 52 facing each other. Each elastic locking part 51, 52 has a different length in the direction of the wire 2a, and the length of one elastic locking part 51 is different from the length of the other elastic locking part 51.
Lf is equal to or slightly smaller than the length Le of the sub-small hole portion 33 of the insertion hole 30, and the length Lg of the other elastic locking portion 52 is equal to or slightly smaller than the length Lc of the large hole portion 31. There is. Each elastic locking part 51, 52 has a taper 51a, 52a and a step 51b on the outer surface side of the tip part.
52b. At the center of the support member 50,
A storage recess 53 is formed, and insertion grooves 55, 55 for inserting the wire 2a are formed in two end face portions 54, 54 substantially perpendicular to the wire 2a.

After the connecting member 40 is inserted into the insertion hole 30, as shown in FIG. is inserted into the sub-small hole 33. At this time, it enters each hole 31, 33 while being elastically deformed by the guiding action of tapers 51a, 52a, and returns to its original shape when step 51b, 52b reaches the edge of each hole 31, 33. And this step 5
The support member 50 is reliably attached to the slider 8 by the locking action between the edges of the holes 31 and 33 and the support member 50. In this state, the base portion 41 of the connecting member 40 described above is stored in the storage recess 53 of the support member 50. Thereby, the connecting member 40 is reliably supported by the support member 50 and will not come off the slider 8.

As described above, the slider 8 and the wire 2a can be connected by simply inserting the connecting member 40 and the supporting member 50 into the insertion hole 30 of the slider 8. Further, the structure is simple because the slider 8 is simply provided with the insertion holes 30 as means for inserting and locking the respective connecting members 40.

It should be noted that each member constituting the coupling mechanism 20 between the sub-wire 2b and the slider 8 is also constructed in the same manner as the configuration of each member described above.

In the above configuration, the wind regulator 1
When the regulator handle (not shown) is manually operated, the wire 2a is driven via the drive device 3, and the connecting member 40 fixed to the wire 2a engages with the insertion hole 30 of the slider 8. Then,
A slider 8 moves up and down along the main rail 5 to open and close the window glass of the door.

Furthermore, the weight of the window glass can be supported by the balance spring 11 due to the locking action between the connecting member 40 fixed to one end of the sub-wire 2b and the insertion hole 30 of the slider 8.

This invention is not limited to the above-mentioned embodiments, and various embodiments are possible. For example, a V-shaped plate may be used as the connecting member, the trough of the plate may be placed at a predetermined position of the wire, and both sides of the plate may be caulked and fixed in this state.

Effects of the invention As explained above, the wire can be connected to the slider simply by inserting the pair of elastic locking parts of the connecting member and the supporting member to which the wire is fixed into the insertion hole formed in the slider. Connection work can be easily performed. Further, since it is only necessary to form an insertion hole in the slider, the structure is simple and the manufacturing cost can be reduced. Also,
Since the pair of elastic locking portions prevents the support member from coming off the insertion hole of the slider, the connecting member can be reliably fixed to the slider.
