[0007]

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a main yoke 10 for a wiper used to connect a wiper to an arm 1 of the type shown in FIG.
A holding frame 11 fixed to the back portion of the main yoke 10 of the wiper shown in FIG. 2, a connecting frame 21 fitted into the holding frame 11, and a holding frame. 11 and a pin 41 penetrating through the pin insertion hole of the connection frame 21.

As shown in FIG. 2, the holding frame 11 is formed in a concave shape in cross section, and is formed as an inverted channel type having a horizontal bottom surface. The opposing walls 12 and 13 forming the holding frame are formed such that one end has a high height and the other end has a low height. Pin insertion holes 14 and 15 are formed in opposing walls 12 and 13 at portions where the height is increased. Further, in the portion where the height of the opposing wall is reduced, projection insertion holes 16 and 17 are formed so as to face the longitudinal edge side so as to face each other.

An arm connecting frame 21 is mounted on the holding frame 11 having the above-described structure.

As shown in FIG. 3, the arm connecting frame 21 has a horizontal lower side, a vertical edge on one side, and a vertical edge on a lower side, and a rounded edge on the other side. 22 and 23 are opposed to each other, and the connecting plate 24 is arranged on the side where the height of the edge of the opposed plates 22 and 23 is reduced, and the end on the side where the height of the plates 22 and 23 arranged on both sides is reduced. Cuts 25, 26 are formed in the vicinity of the edge, and the space between the edge and the cut is formed as a piece-shaped projection forming part 27, 28 with a lower side as a rounded edge, and both outer surfaces of the piece-shaped projection forming parts 27, 28 Projection 29
A pin insertion hole 3 formed in the thick portion 2 of the arm 1 on the side where the height is increased, and a pin insertion hole having an inclined surface 5 from the bottom surface in the pin insertion hole. A pin insertion portion 31 of the same type as the pin insertion portion 6 including the pin guide groove 5 slightly narrower in diameter than the diameter of the pin insertion hole reaching No. 3 is formed.

As shown in FIG. 3, the pin insertion portion 31 of the connecting frame 21 of the arm has a pin insertion hole forming portion formed between the plates 22 and 23 disposed on both sides to form the pin insertion portion 31. It is formed by bridging a guide tube 32 having a tube surface cut in a chord shape in the longitudinal direction. This state is shown in FIG. 4 as a partially cutaway view.

The present invention provides a holding frame 11 constructed as described above.
Is fixed to the back of the main yoke 10 of the wiper according to a conventional method.

Next, the arm connecting frame 2 constructed as described above is used.
1 is aligned with the pin insertion holes 14 and 15 of the holding frame 11 and the pin insertion portion 31 of the connecting frame 21 of the arm, and
1 and the pin insertion holes 14 and 15 of the holding frame 11 and the connecting frame 2
The pin 41 is penetrated through a guide tube 32 cut out in a chord shape forming the pin insertion portion 31, and both ends of the pin 41 are caulked as shown in FIG. 5, and the connecting frame 21 is rotatably mounted on the holding frame 11. .

By this operation, a connecting tool composed of the holding frame 11 and the connecting frame 21 is completed.

Next, the arm 1
The means for mounting is described. As shown in FIG. 6, the connecting frame 21 mounted on the holding frame 11 of the connecting tool is set in a state where the bottom side of the connecting frame 21 is raised almost vertically. In this state, the chord-shaped notched guide cylinder 32 disposed in the pin insertion portion 31 of the arm connection frame 21 is connected to the pin insertion holes 14 and 15 of the holding frame 11 and the pin insertion portion 31 of the arm connection frame. The chord-shaped notch penetrated by the pin 42 and cut in a chord shape coincides with the inclined surface 4 of the guide groove 5 forming the pin insertion portion 6 formed in the arm shown in FIG. State.

In this state, as shown in FIG. 6, the inclined surface 4 of the guide groove 5 forming the pin insertion portion 6 of the arm 1 and the chord of the guide tube 32 cut through the pin 42 in a chord shape. By aligning the notches and pushing down the arm 1 toward the chord-shaped notched guide tube 32 as shown in FIG.
As shown in FIG. 5, the guide tube 32 cut in a chord shape can be fitted into the pin insertion hole 5 of the pin insertion portion 6 of the arm 1. Since the guide groove 5 of the pin insertion portion 6 of the arm 1 is made narrower than the diameter of the pin insertion hole 3, the chord-shaped notched guide cylinder 32 penetrating through the pin insertion hole 3 is provided with the pin of the arm. It will not come off from the insertion hole.

After this operation, the transfer plate 24 of the connecting frame 21 is pushed down, so that the projecting projection forming portions 27, 28 formed on both sides of the transfer plate 24 of the arm connecting frame 21 are held as shown in FIG. It will be stuck in the part 11. Since the projections 29 are formed on the outer sides of the projecting projection forming portions 27 and 28, the projections 29 fit into the pin insertion holes 16 and 17 of the holding frame 11. By this operation, as shown in FIG. 7, the arm 1 can be connected to the connecting tool disposed on the back of the main yoke 10 of the wiper.

When removing the arm 1 from the connecting tool,
By slightly squeezing the projecting portion of the connecting frame 21, the projection fitted into the pin insertion hole of the holding frame is pulled out from the pin insertion hole. In this state, the connecting frame 21 is pulled up from the holding frame 11 to be in the state shown in FIG.
In this state, the pin insertion portion of the arm can be pulled out of the pin having the above-described configuration penetrating the holding frame 11 and the connection frame 21, and the arm can be removed from the connection tool.

[0019]

According to the present invention, the above-mentioned structure is provided.
The number of parts can be reduced, the structure can be simplified and the cost can be reduced, and the arm of the type shown in FIG. 1 can be easily and reliably connected to the wiper, and can be easily and reliably removed from the connection tool.
