Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a window regulator device.

<Prior Art> As a conventional window regulator device, the one shown in Figs. 4 and 5 is known, for example [Automotive Engineering Complete Book Volume 13 (1981 (published by Kikizankaido), Vol. See page 135].

First, the structure of this window regulator device will be explained based on FIG. ■ is a car door, and this door l
The window glass 2 is supported by front and rear rails 3 so as to be movable up and down. A bracket 4 is attached to the lower end of the window glass 2, and a loop-shaped flexible wire 5 is secured to the bracket 4. The flexible wire 5 is fed in mutual directions by a regulator unit 6 assembled to a door inner panel (not shown), and is adapted to move the window glass 2 up and down. That is, the regulator unit 6 is provided with a rotating shaft 7 that projects toward the interior of the vehicle, and a base end 9 of a regulator handle 8 for operating from the interior of the vehicle is attached to this rotating shaft 7. be. When the occupant turns a knob 10 provided at one end of the regulator handle 8, the rotating shaft 7 is rotated, the flexible wire 5 is sent, and the window glass 2 is raised and lowered. ing.

Now, as shown in FIG. 4, parts such as an armrest A1, a door pocket B, and a speaker C are arranged on the door trim 11 around the regulator handle 8. Further, an instrument panel D, a seat E, etc. are also arranged close to the regulator handle 8. Considering the operability when turning the knob 10 of the regulator handle 8 along the circular rotation path X, the distance a − between these peripheral parts A-E and the rotation path X of the regulator handle 8 is A certain appropriate interval is determined for e corresponding to each of the peripheral parts A to E.

<Problem to be Solved by the Invention> However, in such a conventional technique, in addition to occupying a circular rotation trajectory X with a radius approximately corresponding to the length of the regulator handle 8, each peripheral component A Since it is necessary to ensure proper spacing a - e corresponding to -E, the degree of freedom in layout of the peripheral components A to E is greatly restricted. Therefore, all cars with such a manual regulator handle 8 have roughly the same layout of peripheral parts A to E.
It was not possible to create a unique layout. Furthermore, among the peripheral parts A-E, the armrest A and the instrument panel D located above the rotational trajectory X are
In particular, it is easy to approach the rotation path X, and depending on the type of vehicle, it may not be possible to sufficiently secure the appropriate distances a and d from the armrest A and the instrument panel D.

The present invention has been made by paying attention to such conventional technology, and it is an object of the present invention to provide a window regulator device that can increase the degree of freedom in the layout of peripheral components.

Means for Solving the Problems> In order to achieve the above object, the window regulator device according to the present invention has the base end of the regulator handle in a non-rotatable state relative to the rotating shaft, and the regulator handle It is installed so as to be slidable in the longitudinal direction, and is engaged with a roughly oval cam groove on either the rotating shaft mounting surface of the regulator unit or the back surface of the proximal end of the regulator handle, and into the cam groove on the other side. It forms a cam follower.

<Operation> When the regulator handle is turned, the cam follower moves along the approximately elliptical cam groove, so the rotation locus of the regulator handle also becomes approximately elliptical. For example, if this rotational trajectory is made into a horizontally elongated roughly elliptical shape, the rotational trajectory will be like a conventional circular rotational trajectory squashed vertically, so there will be more space above and below this rotational trajectory. I can do it,
This increases the degree of freedom in the layout of peripheral components.

Embodiment A preferred embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Incidentally, the same reference numerals are given to the parts common to the conventional one, and redundant explanation will be omitted.

12 is a regulator unit, 13 is a door inner panel, 14 is a door trim, 15 is a regulator handle,
Each is shown. The regulator unit 12 is provided with attachment parts 16 at three locations, and the attachment parts 16 are attached to the door inner panel 13 with screws 17. The regulator unit 12 is provided with a long plate-shaped rotary shaft 18 having a constant thickness and protruding from its mounting surface 19. Further, this mounting surface 19 has an oval cam groove 20 surrounding the rotation shaft 18.
is formed. The cam groove 20 has a vertically elongated elliptical shape, and is formed so as to be slightly displaced downward from the center of the mounting surface 19.

And, on the door inner panel 13 and the door trim 14,
Attachment holes 21 and 22 are formed for each of the rotation shafts 18 to protrude toward the interior of the vehicle. Further, a rectangular engagement hole 24 is provided at the base end 23 of the regulator handle 15.
is formed. This engagement hole 24 is set to have a width approximately corresponding to the thickness size of the rotating shaft 18 and a size L that is longer than the cross-sectional length size l of the rotating shaft 18. Then, the rotary shaft 18 is inserted into this engagement hole 24.
is inserted, and a clip 26 is fitted to a stopper 25 provided near the tip of the rotating shaft 18 to prevent it from coming off.

Therefore, although the regulator handle 15 cannot rotate relative to the rotating shaft 18, it is slidable in the longitudinal direction N thereof. Further, on the back surface 27 of the base end portion 23 of the regulator handle 15, there is provided the regulator unit 1 on the opposite side of the engagement hole 24 from the knob 28 side.
A cam follower 29 that can freely engage into the cam groove 20 of No. 2 is formed. This cam follower 29 has a structure in which a rotating roller 29b is attached to a shaft portion 29a. In addition, 30 is a cap for covering the engagement hole 24 of the base end 23, and engages the three integrally formed claws 31 into the three recesses 32 provided on the base end 23. It is installed by matching.

Next, the operation of this window regulator device will be explained.

When the regulator handle 15 is rotated by turning the knob 28 of the regulator handle 15, the cam follower 29 formed at the base end 23 of the regulator handle 15 is rotated.
However, when the knob 28 is brought upward, the entire regulator handle 15 moves downward due to the engagement between the cam follower 29 and the cam groove 20. When the knob 28 is brought downward, it is pulled upward, so that the engagement hole 24 slides vertically relative to the rotation shaft 18 while the regulator handle 15 is rotating, and the regulator handle 15 is pulled upward. The rotation locus Y of the 15 knob 28 is a horizontally long ellipse. Moreover, since the cam groove 20 is displaced downward with respect to the rotation shaft 18, this oblong elliptical rotation locus Y is also overall It is displaced downward. Since peripheral parts A to E are generally not often laid out in the lateral direction of the rotation trajectory Y, even if the rotation trajectory Y has a horizontally elongated oval shape, there is little disadvantage. On the other hand, in the vertical direction of the rotation trajectory Y, various peripheral parts A
-E are often laid out in close proximity, so if the rotation trajectory Y is made into a horizontally long oval shape as in this example,
As a result, there is more space above and below this rotational trajectory Y.
The degree of freedom in layout of peripheral components A to E increases accordingly. Moreover, since the entire rotational trajectory Y is displaced downward, the severe positional relationship between the armrest A and the instrument panel D, which were previously particularly close to each other above the rotational trajectory, is alleviated. The degree of freedom regarding the layout position and size of panel D is particularly increased.

Since the rotation locus Y thus has a horizontally long elliptical shape, the operation range Y in the horizontal direction is longer than the operation range Y2 in the vertical direction in the rotation locus Y. When comparing the operability in the horizontal operation area Y1 and the vertical operation area Y2, it is found that applying force in the horizontal direction is easier to operate than applying force in the vertical direction. , is known for its ergonomics, so the window regulator device of this example is unexpectedly superior in terms of operability compared to the conventional circular rotation trajectory, allowing easy and effortless steering wheel operation. It can be realized.

In the above description, the rotation locus Y has a horizontally elongated oval shape, but it may be vertically elongated or diagonal. In addition, the cam groove 20
Contrary to the above embodiment, the cam follower 29 may be formed on the back surface 27 of the base end portion 23 of the regulator handle 15, and the cam follower 29 may be formed on the mounting surface 19 of the rotating shaft 18 in the regulator unit H2. In addition, cam follower 29
may be formed at a position on the knob 28 side with respect to the engagement hole 24.

<Effects of the Invention> The window regulator device according to the present invention has the content as described above, and since the rotation locus of the regulator handle is approximately elliptical, the short axis direction of the approximately elliptical shape is Free up space. Therefore, by setting this roughly elliptical rotation locus in the optimal direction while taking into account the positions of surrounding parts, it will be easier to secure the appropriate distance for operating the regulator handle, and there will also be space in the direction of its short axis. Since there is a margin in the direction, the degree of freedom in layout of peripheral components in that direction increases accordingly.

In addition, if the rotation locus is a horizontally elongated roughly elliptical shape as in the example, the operating range in the horizontal direction, where it is easy to apply force, is longer than the operating range in the vertical direction, where it is difficult to apply force. , it is also superior in terms of operability compared to the conventional circular rotation locus.
