Abstract
A wiper blade 1 is connected to a yoke 5 by means of a clip 7 provided with lugs 8 so that it can slide along the blade, a resilient gripping portion 9 for gripping the yoke, and an anchoring element 10 which is anchored in the bead 4 of the blade. In modifications, see Fig. 5, the gripping portion may slide under claws 11 of the harness and grip them. The anchoring element need not be in the form of a blade, but may take the form of teeth 14, see Fig. 7. The wiper blade may have a metallic or thermoplastics backing strip 2. In the latter case, the anchoring element may be anchored in the strip. <IMAGE>
Description
SPECIFICATION
Wiper blade assembly
The present invention relates to replacement blades for windscreen wipers utilised on automobile vehicles for wiping surfaces such as windscreen, rear windows or headlamps.
The known windscreen wipers comprise a harness mounted for pivoting on the free extremity of a wiper arm and carrying a wiper blade. The wiper blade itself comprises a blade rubber which is stiffened by a vertebra of metal or thermoplastic material. The wiper harness is generally formed of several yokes the fork-shaped extremities of which grasp the wiper blade.
In order to avoid the replacement of the harness when the wiper blade rubber is worn, it has been proposed to fit the wiper blade in detachable manner on its harness and consequently to provide replacement blades for these windcreen wipers.
To this end, the wiper manufacturers have provided complementary devices on the harness and on the blade, ensuring this detachable fitting. However in general the known replacement blades cannot be fitted on all existing types of harness, they are of quite high price and their fitting is often difficult.
The invention aims at obtaining a new replacement blade which can be adapted to all types of harness, which is economical and simple, and the fitting of which is easy and certain.

FIGURE 13 is a perspective view of the rider piece according to FIGURE 12.
In accordance with the invention this aim is achieved by a replacement blade for windscreen wipers which comprises a blade rubber stiffened by a vertebra of metal or thermoplastic material, and means for its fitting on the fork-shaped extremities ofyokes constituting a harness and forming part of the wiper, characterised in that the said fitting means are constituted by a rider piece mounted for sliding on the blade, the said rider piece comprising a gripper which is elastically deformable so as to come to lodge on both sides of a yoke of the harness, and an element for anchoring the rider piece in the blade.
With the replacement blade according to the invention the constitution of the actual blade is very simple and the rider piece, which likewise can be very simple, permits very easy fixing, with great security, of this blade on all types of wipers with replaceable blade. Moreover it is not necessary that the length of the blade should be strictly adapted to the windscreen wiper, which permits of reducing the number of lengths necessary to cover the different types of windscreen wipers. It is further possible for the blade to extend further on one side in relation to the harness, which can be advantageous for certain models of automobile vehicles.
Various forms of embodiment of such a blade are represented by way of non-limitative examples in the accompanying drawings, wherein: In the form of embodiment according to FIGURES 1 to 3, the blade comprises a blade rubber 1 stiffened by a metallic vertebra 2 having a longitudinal slot 3 through which there passes a bead 4 of the blade rubber 1. The blade is intended to be fitted on a harness comprising a yoke 5 the extremities of which, such as 6, form a fork which grasps the sides of the metallic vertebra 2.
In accordance with the invention the blade carries a rider piece 7 which is mounted for sliding on the lateral edges of the metallic vertebra 2 by means of two curved-in lugs 8. The rider piece 7 also comprises a gripper 9 the arms of which can be spaced elastically from one another in order to reclose around the yoke 5, above the latter. The rider piece further comprises an appendage 10 which is driven into the bead 4 of the blade rubber 1.
For fitting, the rider piece 7 is positioned as necessary on the metallic vertebra 2, the sliding being effected by a slight pivoting in the clockwise direction (in FIGURE 1) permitted by the play existing between the lugs 8 and the metallic vertebra 2. Then the blade is caused to slide between the extremities 6 of the yokes 5 until the gripper 9 comes into contact with the yoke 5 with which it is to co-operate. The elastic deformation of the gripper 9 permits of imprisoning the yoke 5 while tending to rock the rider piece 7 in the anti-clockwise direction (in FIG
URE 1), which ensures the anchoring of the appendage 10 in the bead of the rubber4. Dismantlement is effected by the converse operation. The rider piece 7 can be metallic or of thermoplastic material.
The form of embodiment according to FIGURES 4 and 5 is identical with the preceding, except that the gripper 9 is designed to penetrate between the prongs 11 of the fork constituted at the extremity 6 of the yoke 5, in the space left available between the bottom of this fork and the apex of the bead 4. To this end the gripper 9 is substantially flat and its two arms are terminated by rounded portions 12 each forming a shoulder 13 which lodges behind the extremity 6 of the yoke 5.
In the form of embodiment according to FIGURE 6, the gripper 9 recloses on the fork-shaped extremity 6 of the yoke 5, instead of reclosing upon the yoke itselft as in the case of FIGURES 1 to 3.
In the form of embodiment according to FIGURES 7 to 11, as in the case of FIGURES 4 and 5, the gripper 9 penetrates between the prongs 11 of the fork constituted on the extremity 6 of the yoke 5.
Moreover the interior of the arms of the gripper 9 comprises longitudinally staggered teeth 14 which penetrate into the base of the bead 4. The rider piece 7 is not in contact with the metallic vertebra 2 and thus has no lugs 8.
The fitting of the rider piece 7 is explained in FIG
URES6to 10. The arms of the gripper 9 are moved apartforthe rider piece to be placed in position on the bead 4 (FIGURE 7). The arms then elastically approach one another (FIGURE 8), with the teeth 14 penetrating into the bead 4. When the gripper 9 is driven between the prongs of the fork 11 of the yoke 5, this anchorage is acentuated (FIGURE 9) and at the end of the driving in the arms of the gripper 9 separate slightly from one another as soon as the shoulders 13 have passed the arms 11, the teeth 14 however remaining sufficiently anchored in the bead 4 to ensure the fixing of the blade (FIGURES 10 and 11).
The form of embodiment according to FIGURES 12 and 13 is more particularly intended for a blade the stiffening vertebra 2 of which is of thermoplastic material, the blade rubber 1 comprising no protruding bead. The rider piece 7, which is metallic, comprises a gripper 9 which comes to reclose around the yoke 5, while the lugs 8 are elastically transversely deformable. The anchoring of the rider piece 7 is effected by points 15 which are formed in the body of the rider piece and are driven into the upper surface of the vertebra 2 of thermoplastic material, when the rider piece 7 is driven in so that its lugs 8 may come to grasp the vertebra 2 laterally.
