【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. The embodiment described below is one in which the present invention is applied to the wiper blade of the type having two auxiliary stairs 5 on the main stay 7 shown in FIGS. 3 and 4 described above. Of course, it can be applied to a wiper blade of a type having one auxiliary stay, for example.

FIG. 1 is an exploded perspective view of parts constituting the present invention. Only one sub stay 5 is shown, and only one main stay 7 is shown.

The rubber ribbon 1 is long in order to wipe the wind glass over a wide range, and has a uniform inverted cross-sectional shape in the longitudinal direction, and has a T-shaped necked portion 15 at the top. Have.

The ribbon holder 3 for holding the rubber ribbon 1 is formed in a substantially rod shape having a uniform cross-sectional shape in the longitudinal direction, and has a cross section T through which the T-shaped reduced neck portion 15 of the rubber ribbon 1 is inserted. A character-shaped internal groove 17 is formed, and the T-shaped neck portion 15 of the rubber ribbon 1 is inserted into the internal groove of the ribbon holder 3. Further, linear outer grooves 19 are formed in the longitudinal direction of the ribbon holder 3 on both sides of the upper side of the ribbon holder 3, and these outer grooves 19 are gripping portions 11 (the right one in FIG. 1) of the auxiliary stay 5 which will be described later. The claws 29 can grip the outer grooves on both sides and slide. The grip portion 11 is formed integrally with the auxiliary stay 5 by bending a sheet metal. The grip portion 11 is formed in a substantially U-shape facing downward, and has inwardly facing claws 29 at both ends of the U-shape. In addition, hook holes 21 are formed on the upper surfaces of both ends of the ribbon holder 3.

At both ends of the ribbon holder 3, in order to prevent the rubber ribbon 1 having the above-mentioned cross-sectional shape fitted in the internal groove 17 of the ribbon holder 3 from falling off, and to prevent the claw 29 of the grip portion 11 of the auxiliary stay 5. In order to prevent the stoppers from falling off, resin stoppers 23 and 25 are attached respectively. Of these stoppers, one stopper 23 (on the left side in FIG. 1) has one grip portion 11 (on the left side in FIG. 1) located at the outer end of the auxiliary stay 5 on the ribbon holder 3 (on the left side in FIG. 1). The stopper 2 is fixed so that the grip portion 11 grips the outer groove 19 of the ribbon holder 3 together with the stopper 23 in order to fix the rubber ribbon 1 to the end portion and to prevent the rubber ribbon 1 from falling off from the ribbon holder 3. 3 has a constricted portion 27 formed by scraping off both sides of the body and the abdomen.

The constricted portion 27 formed on the stopper 23 can be inserted between the claws 29 of the grip portion 11 of the auxiliary stay 5 in a state where the stopper 23 is laterally oriented. . That is, the thickness of the constricted portion 27 (the dimension in the vertical direction on both sides in the figure) is smaller than the gap between the claws 29 of the grip portion 11. By this lateral rotation, when the constricted portion 27 of the stopper 23 is fitted into the grip portion 11 of the auxiliary stay 5 and then its orientation is restored, the constricted portion 27 is correctly fitted into the grip portion 11 of the auxiliary stay 5, and the grip portion is held. It is designed to be properly gripped by 11. That is, the width of the narrowed portion 27 of the stopper 23 is wider than the size of the gap between the claws 29 directed to the inner sides of the grip portion 11, and after the grip portion 11 is properly fitted, 11 has a cross-sectional shape of a size large enough to prevent rattling.

The base of the constricted portion 27 of the stopper 23 forms an inclined surface 32 having a downward advancing angle from the upper side to the lower side, and the gripping portion 11 is also formed with an advancing angle from the upper side to the lower side. It has a shape that matches the inclined surface 30.

Further, the stopper 23 is hollowed out below the abdominal surface of the constricted portion 27 except for the constricted portion 27 in which both sides of the torso and the abdomen are shaved off, and passing through the abdominal surface to a flange 37 provided at the rear end portion. A ribbon holder fitting insertion groove that fits and inserts into the outer groove 19 of the ribbon holder 3 is provided (FIG. 2). Further, a hook portion 33 is formed on the top surface of the stopper 23 by the U-shaped notch 31. A hook 35 (FIG. 2) projects below the hook portion 33. The position of the hook 35 coincides with the hook hole 21 formed at the end of the ribbon holder at a position where the stopper 23 is sufficiently fitted to the ribbon holder 3.

Of the two stoppers, the other stopper 25 (on the right side in FIG. 1) does not have the constricted portion of the stopper 23, but has a shorter dimension as a whole, so that the stopper 23 has a shorter dimension. It has the same structure as. That is, the hook portion 33 and the outer end 19 of the ribbon holder 3 have a cross-sectional shape for fitting, and a flange 37 is formed at the rear end portion to prevent the rubber ribbon 1 from falling off. It has become.

The assembly of this embodiment will be described below. That is, at the time of assembly, the neck portion 15 of the rubber ribbon 1 is fitted and inserted in the longitudinal direction of the inner groove 17 of the ribbon holder 3 to assemble, and then both grip portions 11 of the auxiliary stay 5 on the right side in FIGS. From one of the tips of the ribbon holder 3, the claws 29 provided on the grip portion 11 are fitted and inserted so as to grip the outer groove 19 of the ribbon holder 3.

Next, the stopper 25 (right side in FIG. 1, corresponding to 13 in FIG. 4) is fitted and fixed to the end of the ribbon holder 1. After the stopper 25 is also fitted, the rubber ribbon 1 fitted and inserted in the internal groove of the ribbon holder 3 cannot move in the fitting direction due to the action of the hook portion 33. The grip portion 11 of the auxiliary stay 5 allows the rubber ribbon 1 and the ribbon holder 3 to slide in the longitudinal direction by bending.

The other tip side of the ribbon holder 3 is one grip portion 11 of the auxiliary stay 5 arranged on the left side in FIGS. 3 and 4, that is, the grip portion 11 arranged on the right side of the auxiliary stay 5 shown in FIG. In the same manner as described above, the outer groove 19 of the ribbon holder 3 is fitted by being held by the claws 29 of the holding portion 11. On the other hand, the other grip portion 11 (on the left side in FIG. 1) grips the stopper 23 as shown in FIG. That is, the constricted portion 27 is inserted between the claws 29 of the grip portion 11 of the auxiliary stay 5 in a state where the stopper 23 is rotated and laid sideways. After the insertion, the direction of the constricted portion 27 is restored so that the constricted portion 27 can be properly gripped. Then, the end portion of the groove of the stopper 23 which is fitted and inserted into the outer groove of the ribbon holder is fitted and inserted into the end surface of the end of the outer groove 19 of the ribbon holder 3. At the time of this insertion, the hook portion 33 of the stopper 23 comes into contact with the top surface of the ribbon holder 3 and is lifted up, and then it is locked so as to fall into the hook hole 21. Due to this locking, the stopper 23 no longer moves in the direction opposite to the fitting.

By assembling in this way, as shown in FIG. 2, the auxiliary stay 5 is in a state in which one grip portion 11 grips the one stopper 23 and is fixed. The other gripping portion 11 (right side in FIG. 1) of the sub-station 5 grips while allowing sliding, and allows sliding in the longitudinal direction due to bending of the ribbon ribbon 1 and the ribbon holder 3.

Further, the assembly can be easily carried out by holding the stopper 23 on the auxiliary stay 5 and fitting it to the ribbon holder 3, so to speak, one-touch assembly can be carried out.

Further, as the auxiliary stay 5, the ribbon holder 3, and the rubber ribbon 1, the conventional ones can be adopted as they are, and the stopper 23 can be adapted to the sectional shape of the grip portion 11 of the auxiliary stay 5 and the end portion of the ribbon holder 3. This embodiment can be easily carried out by molding with a resin. Therefore, the cost can be kept low.
