Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wind wiper for wiping a window of an automobile or the like.

[0002]

[Prior Art]

 As shown in FIG. 5, an automobile wind wiper 6 includes a head 1 fixed to a pivot shaft, an arm 2 attached to the head 1 by a hinge pin 3 so that the arm 2 can be locked back in a direction away from the glass surface. This arm 2 is composed of an arm spring 5 that constantly urges the arm 2 toward the glass surface. Reference numeral 4 indicates a spring guide.

The lockback of the arm 2 prevents the wiper rubber from freezing on the glass surface during snowfall and facilitates cleaning of the glass surface, as shown in FIG. Is to tilt the wind wiper 6 away from the surface of the glass 7 as indicated by a virtual line.

[0004]

[Problems to be solved by the device]

 However, when the hood or the rack 8 is opened during full lockback, the edge of the hood or the rack 8 interferes with the arm 2 as shown in FIGS. 6 and 7, and the scratches on the outer plate or the wiper pivot is broken. There is a point.

An object of the present invention is to provide a wind wiper that solves the above conventional problems.

[0006]

[Means for Solving the Problems]

 The gist of the present invention for achieving the above object is to provide a head fixed to a pivot shaft, an arm attached to the head by a hinge pin so as to be able to be locked back in a direction away from the glass surface, and this arm is always made of glass. In a wiper consisting of an arm spring biased in the surface direction, one end of the link is rotatably attached to the arm and biased in the lockback direction by a spring, and the other end of the link is engaged with the head. Then, a guide groove for holding the arm in the semi-lockback position and a semi-lockback release lever for opening and closing the entrance of the guide groove are provided.

[0007]

[Action]

 With the above configuration, the arm can be positioned at the semi-lockback position where the edges of the hood and the racket do not interfere with each other, and the wiper rubber can be prevented from freezing on the glass surface during snowfall, and the glass surface can be easily cleaned.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a head fixed to a pivot shaft (not shown), 2 is an arm attached to the head 1 by a hinge pin 3 so as to be able to lock back in a direction away from the glass surface, and 5 is an arm 2 An arm spring urged in the glass surface direction, and 4 is a spring guide.

According to the present invention, one end 10a of the link 10 is rotatably attached to the arm 2 while being biased in the lockback direction by a spring 13a.

Further, the head 1 has a guide groove 14 for holding the arm 2 in a semi-lockback position by engaging the other end 10 b of the link 10 in the vicinity of the hinge pin 3, and a lower portion of the guide groove 14. A relief groove 15 for freeing the other end 10b of the link 10 in a normal state of the arm 2 and a semi-lockback release lever 11 provided with a restraining portion 11a for opening / closing the entrance of the guide groove 14 are provided. .. The semi-lockback release lever 11 is rotatably attached to the head 1 by a pivot 12, and the restraining portion 11a is constantly urged by a spring 13b so that the guide groove 14 is opened and abutted against the stopper 16. ing.

Since the present invention has the structure as described above, the normal state of FIG. 1, that is, the other end 10b of the link 10 is located in the escape groove 15, and the arm 2 is placed on the same axis as the head 1. The wiper rubber (not shown) is in contact with the glass surface.

To change from the normal state to the semi-lockback state, as shown in FIG. 2, the arm 2 is once rotated to the full lockback position of the virtual line. As a result, the link 10 is always biased in the lockback direction by the spring 13a, so that the other end 10b of the link 10 escapes from the escape groove 15 following the rotation of the arm 2.

After that, when the arm 2 is returned from the full lockback position to the semi-lockback position, even if the other end 10b of the link 10 engages with the guide groove 14 and the arm 2 opens the hood or the rack 8, The edge is fixed at the semi-lockback position where it does not interfere with the arm 2.

When the arm 2 is returned from the semi-lockback position to the normal state, the arm 2 is once rotated to the full lockback position. This causes the other end 10b of the link 10 to escape from the guide groove 14. At this time, as shown in FIG. 3, the semi-lockback release lever 11 is rotated counterclockwise in FIG. 3 so that the entrance of the guide groove 14 is closed by the restraint portion 11a, and the arm 2 is attached to the arm spring 5. When the link 10 is lowered toward the glass surface by the action force, the other end 10b of the link 10 passes through the guide groove 14 and is inserted into the escape groove 15 to be returned to the normal state of FIG.

[0015]

[Effect of the device]

 As described above, the wind wiper according to the present invention comprises an arm attached to the head by a hinge pin so as to be able to be locked back in a direction away from the glass surface, and an arm spring that constantly urges this arm toward the glass surface. In the wiper, one end of the link is rotatably attached to the arm and urged in the lockback direction by a spring, and the other end of the link engages with the head to semi-lockback the arm. Since the guide groove that holds the position and the semi-lock back release lever that opens and closes the inlet of this guide groove are provided, the semi-lock does not interfere with the arm even if the arm is opened with the hood or the racket. It can be fixed to the back position and prevents the wiper rubber from freezing on the glass surface during snowfall. The cleaning of the scan surface to be positioned to facilitate state has the advantage that it is.
