Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a windshield or similar surface wiper comprising one arm removably coupled to one blade by one connector.

The term analogous surface herein refers to a surface other than the windshield surface to which a wiping action is applied, such as a headlight glass or a bank mirror.

More specifically, the present invention is disclosed in West German Patent Publication No. 212873.
No. 9 relates to a wiper of the type described in No. 9. The wiper shown in Patent Specification 1A is as follows.

That is, the blade includes an elongated frame having a cross-section inverse to the groove, the frame having mutually parallel sides, a connecting web, and an extending frame extending transversely between the sides of the frame. Has a 'pin pivot'. Thereby, one opening of the cilanib is divided into two longitudinally extending parts by the reference partition. The arm has one hook end with a through hole;
It has one semicircular bent part that is integral with the parallel body part and rim part of the arm. The connector also has a pair of opposing plate-like side surfaces near the side of the frame to align parallel to the frame, and a pair of opposite plate-like side portions on both sides of the connector to support the inner surface of the bent portion of the arm and to receive the pivot pin. one hollow bearing, at least partially cylindrical, extending inwardly and outwardly across the sides of the connector; and one protrusion extending upwardly. A wiper with one plate, one arm and one connector having these characteristics is referred to herein as a "wiper of this type".

According to one known assembly procedure for this type of wiper, the connector is first mounted to the blade pivotably about the pivot pin. The plate is tilted deeply relative to the arm to provide passage for the hook end of the arm through a portion of the opening in the web of the plate. During this initial stage of oblique insertion, the connector is tilted with respect to the blade. Is the free end of the rim portion of the arm a bearing of the connector? After passing, the blade is manipulated so that the bearing of the connector supports the inner surface of the bend of the arm. The arm and connector are then moved relative to each other so that the protrusion on the connector is in the hole in the hook end of the arm. The blade is pivoted relative to both the arm and the connector until it is ultimately substantially parallel to the arm.

The procedure for disassembly is the reverse of that for assembly.The procedure for assembly and disassembly of this type of wiper as described above is such that the arm is locked away from the surface of the windshield or similar to be wiped. It is only suitable for wiper installations where it can be pulled away to the rear position.

In such cases, it can be tilted deeply at or near an angle of 45° to the arm, allowing passage of the arm hook end through a portion of the above-mentioned plaid opening of the arm. becomes. However, when installing the wiper, the end of the arm remote from the plate and one holder supporting the arm with respect to the vibrating wiper shaft may always be hidden in a groove in the scuttle of the vehicle body. This scuttle prevents the arm from being pulled far enough away from the windshield or similar surface on which the wiping motion is to be applied, and prevents the blade from assuming the deep slanted position relative to the arm that is necessary for its assembly. It also prevents

According to the invention, therefore, the invention includes an arm releasably connected to a plate by a connector, and said arm is integral with parallel body and rim portions of said arm. It has one hook end including a semi-circular bend, said end containing an opening for a retention means on the connector, and said plate having two sides parallel to each other. The frame includes an elongated frame of substantially inverted U-shaped cross-section with one connecting web having an opening in the longitudinally extending web and between parallel sides of the frame. Said opening extending in the transverse direction?
a pivot pin which effectively divides the connector into two parts, said connector having two mutually opposed plate-like elements suitable to lie parallel to each side of said frame in said opening; one hollow bearing for receiving and allowing full pivoting of the connector on the inside and for supporting the bend of said arm on the outside; a hollow bearing placed in a fixed position relative to opposite sides of said connector and in said hook end a protrusion extending in one direction to engage an aperture in the frame, the connector having a projection in which the hook end enters a portion of the aperture in the frame; a first position in which the protrusion of the connector can engage an opening in the hook end;
the blade is attached to the arm with the connector in the first position in the wynomy of a windshield or similar surface such that the blade is pivotable about the pivot pin between positions of The connector has a structure such that the hook ends enter one of the openings in the frame while lying generally parallel to each other. - is provided.

In the wiper of the present invention, the blade is kept approximately parallel to the arm throughout assembly and disassembly, so that the arm can perform a wiping motion. It will be appreciated that it is particularly suitable for wiper installations where it cannot be separated too far from the windshield or similar surface to be applied.

Preferably said connector comprises launch means spaced from said bearing for grippingly engaging an edge of said connecting web defining an opening in said brevi. The protrusion on the connector is preferably spaced apart from the bearing. a cross member is provided between opposite sides of the connector and spaced apart from the side of the bearing remote from the projection, a hook end of the arm being formed between the bearing and the cross member; The device may be inserted into one opening. Preferably, the latching means on the connector are spaced apart from the cross member on the side remote from the bearing.

the opening in the hook end of the arm extends through a rim thereof, and the protrusion on the connector projects from a plate-like element joining one longitudinal edge of the connector; The protrusion may extend parallel to both side surfaces of the connector. Alternatively, the opening in the hook end of the arm may extend through its body and the protrusion may be V-shaped so that it is mounted on the bearing of the connector by means of a mounting part. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Two wipers for windshield surfaces or rock-like surfaces according to the present invention will be described in more detail below with reference to the drawings as examples only.

Before discussing the overall structure of the connector, it may be convenient to discuss the Wyno ξ-Brevi and wiper arms.

The plate ''10 is of the known type comprising an entire elongated frame having a substantially inverted U-shaped cross section and having mutually parallel sides 12 and one connecting web 14.Pivot pins 16 are attached to both sides of the frame. 12, thereby dividing the opening 14 in the web 14 into two longitudinally extending sections 18b with a reference partition.The opening section 18a is shorter than the opening section 18b. '10 may also include a rubber or comb-like wiper piece 20 and an auxiliary frame 22 (only one shown), which auxiliary frame 22 (only one shown).
6 is pivotably movable with respect to an elongated frame carrying 6.

Arm 30 (Figures 1 and 2) and 30CL (Figure 6)
Figure) is of the known type with a hook end. Each hook end has one semicircular bend 32.32a, which corresponds to the mutually parallel body portions 32, 32a of the arms 30, 30a, respectively.
4,34α and the rim portion 36.36d. There is one mouth 38 within the arm 30 and the rim portion 36
In the case of the arm 30a, the body part 3 extends through the arm 30a.
An opening 38a extends through 4ak.

A fundamental advantage of the invention lies in the disadvantage that the blade 10 can remain substantially parallel to the arm 30 or 30.2, but can be removed from or assembled to the arm 3Q or 30.2 by using a suitable connector.

The connector 50 shown in FIGS. 1-5 is suitably formed of plastic material and includes the opening 18a,
18b, two mutually opposed plate-like side surfaces 52 suitable to extend lj6 close to and parallel to both sides 12 of the elongated frame; one at least partially cylindrical hollow bearing 54 for externally supporting the bend 32 of the arm, and a rim portion 36 of the arm 30 placed in a fixed position with respect to opposite sides of the connector; one protrusion 5 forming a retention means extending in one direction to engage with the
Contains 6.

The protrusions 56 are secured 9 on a plate-like or base member 58 of the connector 50, which supports them between one longitudinal edge 80 of the connector side 52 and one side of the bearing 54. A protruding portion 56 extends between and parallel to both side surfaces 52 of the connector. One cross member 6 in the usage direction of the bearing 54
2 extends transversely between the connector sides 52 and is rigidly connected thereto. One plate-like member forming another base member 60 includes a transverse member 62 and both sides 52.
is tightly coupled to. This member carries a second cross member 64 standing thereon with a free end. Between the bearing 54 and the cross member 62 there is an opening 66 through the connector 50 for receiving the hook end of the arm 30 as described below. The free end of the cross member 64 has a pair of raised portions 7 defining a groove 72 therebetween for receiving the nearer edge of the web 14 of the plate 10, as will be described below.
It carries latch means 68 containing 0.0.

This latching means 68 includes one finger-hole flange 4 which lies across the entire web 14 and is accessible even if the transverse member 62 is used as a finger-hold. The plate-like member 60 is aligned with said one longitudinal edge 80 of the connector side 52 so that the latching means 68 lies in the plane defined by the other longitudinal edge 82 of the connector side 52.

As depicted in FIG. 3, each face 52 of the connector is formed with an open-ended keyhole slot 76, and the underside of the bearing 54 is formed with a corresponding lower longitudinal volume 8, thereby 50 is brought into gripping engagement with the tip 16 and is enabled to assume an inclined position relative to the blade 10 as shown in FIG.

Alternatively, the side surface of the connector may be formed with a hole forming the inner cavity of the bearing, thereby permanently joining the connector and blade.

During the assembly process, the hook end of arm 30 passes through opening 66 in connector 50 between bearing 54 and cross member 62.・'13's first medium work is plate 10 is arm 30
It should be understood that it is important to note that while along the arm 30 the rear 10 remains substantially parallel to the arm 30. Next, the hook end is lowered and the rim portion 36 of the arm 30 and the bent portion 32 are opened at the long opening 18b.
to invade. As the free end of the rim portion 36 passes through the bearing 54 on the pivot pin 16, the plate 10 moves parallel to itself such that the inner surface of the bend 32 engages the outer surface of the bearing 54. Finally, the connector 50 is pivoted (in a clockwise direction as shown in FIG. I am made to exercise. Because the cross member 64 is not supported relative to the connector side 52, the cross member 64 is able to elastically deform toward the cross member 62, thereby facilitating the gripping engagement. It is important to note here that this pivoting movement of the connector 50, on the one hand, causes the protrusion 56 to engage with the aperture 38 extending through the rim portion 36 of the arm 30, thereby supporting the connector on the arm 30. should be understood.

In the preferred application, the plate 10 also allows the connector 50 to remain in place in wiper installation situations where the arm 30 cannot be pulled away from the windshield or similar surface to a locked rear position from the windshield or similar surface on which the wiping movement is to be performed. 10, the protrusion 56 cannot pivot far enough to be pulled out of the aperture 38.

Figure 6 shows a modified example of the connector 50α, which will be described next.
Shown for use with 0a. Connector 50α has basically the same shape as connector 50, but protrusion 56 is not carried by base member 58. Instead of this, the protrusion 56α is one of the 'L' shaped elements.
This is the connector 50, which is provided as one rim part.
α forms a retaining means which assumes a fixed position with respect to both sides 52α, while the remaining rim of said element bears the bearing 5.
4a and functions as a mounting part. Arm 3
0α can be assembled to the plate 10 in the same way as the arm 30. However, the difference here is the connector 50.
When a is rotated clockwise to the assembled position 1σ, the protrusion 56a opens the opening 38f2 to hold the hook end.
The point is that it engages with.
