Description

[Detailed description of the invention] Industrial usage total The present invention relates to a slider for a window regulator.

Conventional technology Automobile window regulators are classified into regulator handles and windshields based on the structure of the opening/closing force transmission mechanism that transmits the opening/closing force of a motor to the windshield.
It can be divided into a nine-arm type, which uses a single arm, a long arm, a parallel arm, etc., and a wire type, which uses flexible wire, plastic tape, etc.

By the way, in the case of the above-mentioned window regulator, for example, as shown in Japanese Patent Publication No. 5O-177R8, a windshield opening/closing force transmission member (the wire type is made of a flexible wire or plastic tape, etc., and the arm type is made of a flexible wire, plastic tape, etc.). Baso has one arm.

A slider is used which is connected to the lower edge of the windshield (corresponding to an X-arm or parallel arm) and which is attached to the carrier plate and engages the guide rail in a straight line. This method is illustrated and explained in FIGS. 8 and 4. Third
In the figure, the slider 1 is connected to the opening/closing force transmitting member 2 and the lower edge of the window glass 8, is attached to the upper and lower parts of the fixed carrier plate 4, and is slidably engaged with the guide rail b.
ing. The slider 1 is made of plastic and has a slit 6 having a groove width approximately equal to the thickness of the convex rail portion 6a of the guide rail 6.

The opposing groove wall surfaces of this slit 6 are set approximately parallel to each other.
The sliding surface 8a of the guide rail 6 with the rail portion 5a
It is composed of K. In the slider shown in FIG. 4, the sliding surfaces 6b of the slider IA with the guide rail 6 are formed into convex arcuate surfaces facing toward each other.

Problems to be Solved by the Invention However, in the nine sliders shown in the above-mentioned GN diagram, since the sliding surfaces 6a are set substantially parallel and are formed as flat surfaces, the slits 6 It was designed to separate the alignment between the width of the groove and the rail g Fs a.

While this prevents the slider 1 from wobbling, the contact area between the sliding surface 6 and the guide rail 6 is large. In addition, dust passes from outside the vehicle through the windshield entrance/exit portion of the window, and contacts the large sliding surface 6a with the large contact area and the rail portion 5.
intrude between a. Due to the action of this dust, when the slider 1 rams against the guide rail 6 when the windshield 3 is opened or closed, it may produce a sliding sound. In the slider IA shown in the figure, since the sliding surfaces 6b are formed into convex arcuate surfaces facing each other, the contact area with the guide rail 6 is small, and the force required to move the slider IA is small. On the other hand, on the other hand,
The degree of wear of the sliding surface 6b is rapid. Therefore, even if the consistency with the plate thickness of the guide rail 6 is increased and the number of assemblies is increased, the number of movements or distance of the slider (IAf) increases under the action of dust as described above. , WI mover IA is t
There is a risk that the windshield 8 will not open and close easily.

Therefore, the present invention provides a slider for a window regulator that can overcome the above-mentioned problems by appropriately setting the contact area of the sliding surface with the guide rail. The present invention has nine configurations in which the sliding surface with the guide rail is formed into an uneven surface.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, with the same reference numerals assigned to the same parts as in the conventional structure.

As shown in FIG. 1, the carrier plate 4 is housed in a door body (not shown), which is a component of the vehicle body around the window, in a vertical direction parallel to the opening/closing direction of the window glass 80.
It is designed to move up and down along the guide rail 6. The upper m part of this gear rear plate 4 is connected to the lower part of the windshield 3 via the glass bottom channel 7.
It is fixed at the same center of gravity behind the TI. A flexible wire serving as the opening/closing force transmitting member 2 for the windshield 3 is connected to the center of gravity of the carrier plate 40 in the longitudinal direction via a bracket portion 8 . This carrier plate 4
Slider mounting portions 9, 10, and 11 are bent and formed at five points in the upper and lower portions and the middle front portion in the vertical direction. Plastic sliders 12, 111, and 14 are fitted into each of the slider mounting portions 9 to 11. The sliding facets 12, 18 of the upper and lower parts of the sliders 12 to 14 are bent at the rear edge of the guide rail 6 and are slidably engaged with the rear rail portion 6b, The remaining (Zheng sliding face 14) is formed by bending forward from the protruding edge of the flange 5C facing the front of the rear rail portion 6b of the guide rail 6, and slidingly engages with the upper front side rail portion ISd. A slit 16 is provided on the front side of the isolator 12° 18 between the rear rail portion 5b and the lower portion. The groove width is approximately the same as that of the slider 12.
．． C is provided through the upper and lower surfaces of 18. A plurality of concave grooves 16 are formed on the substantially parallel groove surfaces 15a of the slit 15.
is formed. Due to the presence of these 41 grooves 16, the surface texture of the n-wall surface 11Sa is an uneven surface, which is formed in the sliding surface with the rear rail portion 51-1 of the guide rail 6. . The plurality of grooves 1s16 are the sliders 1
2. The slits are spaced apart in the vertical direction of the IR and extend in the front and back direction of the IR. Slider 12, 1B
Mounting holes 17 for the slider mounting portions 9 and 10 of the upper and lower portions of the carrier plate 4 are formed in the upper portions of both sides of the slit 16 on the back surface of the carrier plate 4 so as not to pass through to the front surface of the sliding face 12, 13.

The front slider 14 is formed into a J-shape in plan view, and the mounting hole 18 for the front slider mounting portion 11 of the carrier plate 4 is formed in the shape of an M eave on its base end surface. It is formed. A guide rail 6 is attached to the curved tip of the slider 14.
A sliding lip portion 14a to the front rail portion 6d is connected to the neck 14el. Reference numeral 19 is a plastic wire fastening member attached to the wire bracket portion 8 of the rear plate 4, and 20 is a plastic elastic lip protruding from the front upper and lower ends of the wire fastening member 19. , is provided protruding from the inner surface of the web 5e of the guide rail 5 and is slidably pressed against the middle rail portion to bias the carrier plate 4 in the direction 1 away from the guide rail 6. .

According to the structure of the above embodiment, the opening/closing force of the regulator handle or motor (not shown) is transmitted from the opening/closing force transmitting member 2 to the carrier plate 4, and the sliders 12 to 14 are in sliding contact with the guide rail 6. As the carrier plate 4 moves up and down along the guide rail 5, the window glass 8 opens and closes.
Since the sliding surface 11sa has the required vertical width, faces substantially parallel to each other, and is formed into an uneven surface due to the presence of the plurality of grooves 16, the sliding surface 15a guide rail 5
The contact area with the sliding surface is set to be smaller by the amount of the plurality of grooves 16 than that of the case where the sliding surface is formed almost parallel and only a member (see Fig. 8). (See FIG. 4) The width can be set to be large enough to suit the condition of the formation of the plurality of grooves 16. Moreover, the dust that enters between the sliding contact surface 16a and the guide rail 6 is taken into the groove 16 in conjunction with the vertical movement of the sliders 12, 111, and is removed from the sliding contact surface 15a. It is removed from the part where it meets the guide rail 6. Friends, Surikiriko 12.1
This can prevent the squeaky sliding of the windshield 3 and improve the opening/closing performance of the window glass 3.

Figure 2 shows a different example of the present invention.
16A'ft slider 12 (1) The slider 12 is elongated and extends parallel to the direction of movement of the slider 12 (1), and is spaced apart in a direction intersecting the direction of movement. In this embodiment, the concave groove 16 prevents dust that enters between the sliding surface 15a and the guide rail 5.
It can be removed from the slider 12 (Hn) by guiding it downward.

An advantage of the present invention that exceeds the effects of the invention is that the sliding surface of the slider with the guide sole is formed into an uneven surface.

Not only can the contact area with the guide rail be set to a suitable size without being too large or too small, but also the recesses that make up the uneven surface texture of the sliding surface can be checked. This is a new method that can remove dust from between the sliding surface and the guide rail, thereby preventing rattling of the slider and sliding noise, and improving the opening/closing performance of the window glass. effective.
