Definitions
- the present invention relates to a spring cover for a wiper blade holder as well as to a brush holder provided with this spring cover.
- the present invention proposes to remedy these drawbacks and to produce a spring cover for a wiper blade holder which is compact, simple, quick to assemble and ultimately very economical.
- the object of the invention is therefore, and, as a new industrial product, a spring cover for a wiper, said wiper comprising a head for receiving the drive axis of the wiper, a longitudinal yoke articulated at one end on the head and continuing at its other end by the arm intended to receive the brush, a helical spring being disposed longitudinally in the yoke and fixed by one of its ends to the yoke or the arm and, by its other end, at the head, so as to exert on the broom a restoring force towards the windshield while allowing pivoting of the yoke around the articulation axis which connects it to the head, the yoke having a general U-shaped section whose open face, revealing the spring, is closed by the spring cover, characterized in that it comprises means for being fixed on the spring.
- the means for fixing to the spring are latching means and, in such an embodiment, the spring cover may advantageously have, on the side of the drive head of the wiper, a slot latching capable of receiving and trapping the non-helical end portion of the spring which is directed towards said head.
- the spring cover can also be fixed at its other end, arm side, on the spring, but it is preferable, at this level, to fix the spring cover on the yoke or the arm provided that allow, either by the method of attachment, or by the deformability of the spring cover itself, an angular movement of the spring cover relative to the yoke in order to allow it to follow the movements of the spring relative to the yoke.
- the end of the spring on the arm side is very short; it can therefore be difficult to fix the spring cover on the spring and this is the reason why the spring cover may preferably be fixed by snap-fastening on the clevis or on the arm.
- the spring cover can then advantageously include latching or hooking means which are fixed on the end of the arm or on the yoke, preferably on either side of the extension of the spring, the deformation of the concealment being allowed thanks to an articulation connecting the end of the spring cover, which is substantially fixed relative to the yoke, and most of said concealment, which is movable with the spring.
- the articulation can be easily produced inside. desired location by an interruption of said wings, leaving only the core which, thanks to its own possibilities of deformation, allows the spring cover to follow the movements of the spring. It is understood, however, that other more complex embodiments remain possible to achieve an articulation between the fixed part of the spring cover and the movable part of the latter to follow the movements of the spring.
- the invention also has as its object and the new industrial product that constitutes a wiper fitted with a spring cover as defined above.
- FIG. 1 shows a partial perspective view of a wiper according to the invention provided with its spring cover
- - Figure 2 shows a perspective view the spring cover of Figure 1;
- FIG. 3 shows a bottom view of the spring cover of Figure 2;
- FIG. 4 shows a longitudinal sectional view of the spring cover of Figures 1 to 3, mounted on the spring and on the arm extending the yoke, the latter being assumed removed.
- the wiper shown in the drawing comprises a head 1 of usual shape which can be seen fitted on a drive shaft 2 and which is connected, by means of a hinge pin 3, to one end a yoke 4, the other end of which is rigidly attached to the arm of the soot glass 5.
- the yoke 4 has a U-shaped section open at its lower part (windshield side), said yoke being seen turned over in FIG. 1: two wings 4a extend parallel to each other and are connected by a core (not seen in Figure 1); the two wings 4a extend longitudinally beyond the core, on the side of the head 1, to form extensions receiving the articulation 3, this in order to allow an angular movement of the yoke 4 relative to the head 1 around the articulation axis 3.
- the yoke 4 Towards the arm 5, the yoke 4 gradually narrows to its end 4b which is crimped onto the arm 5, an extension 5a, provided with a hole 5b penetrates inside screed 4 for a short distance.
- the helical spring 6, arranged longitudinally in the yoke, has a first filiform end 6a ending in a hook, conventionally hooked in the head 1, and a second much shorter filiform end 6b in the form of a hook penetrating into the hole 5b for hooking the spring.
- the spring 6 moves angularly in the yoke 4 around a point located at the level of the hanging hole 5b.
- the spring cover 7 preferably made of molded or injected plastic, has a general U-shaped cross section which decreases progressively, to follow the section of the yoke, in the direction of the end on the arm side 5 so as to be inserted, without friction, in the yoke 4.
- the core of the U-shaped section of the spring cover 7 has two parts, namely a part of greater length la and a part of shorter length 7b normally making an elbow relative to the part as seen in the drawing.
- the wings of the U-shaped section of the spring cover are also composed of two parts, namely a part 7c corresponding to the core part 7a and a part 7d corresponding to the core part 7b.
- the wings are interrupted by a slot 7e extending to the core and materially separating the wing parts 7c and 7d, so that at this location, the spring cover is reduced to the thickness of the core, which thus forms a deformable or flexible hinge allowing angular movement of the longest part 7.a, 7c relative to the shortest part 7b, 7d; the 7th slots having a divergent shape allowing deformation in both directions.
- the transverse bottom 7f of the spring cover 7 has a central slot 7g, the width of which is slightly less than the diameter of the wire forming the spring 6; the slot 7g opens, in the vicinity of the core 7a, into a transverse slot 7h; the slot 7 g is defined between two internal flanges 7i which project towards the inside of the spring cover.
- the core 7b In the vicinity of the slots 7e, the core 7b has two legs 7 i in the form of a hook. Finally, in its extreme part, the core part 7b. has a longitudinal slot 7k reinforced by a flange 7l, the conformation being such that this end of the spring cover can decrease in width thanks to the presence of the slot 7k and adapt exactly to the place which is offered to it in the yoke 4 During assembly, it can be seen, in particular with reference to FIG.
