JPH05338516A - Structure of double type wiper rubber and blade fixing part - Google Patents

Abstract

PURPOSE:To prevent deformation hardening of a wiper rubber in bent condition by forming the top of the wiper rubber in double fin shape and making the structure of a pin at a fixing part of a bracket and a blade so that it can be disassembled and reassembled. CONSTITUTION:In a wiper rubber A, fins 2 and 3 are formed symmetrically with respect to a fin 1. A fixing part of a bracket C and a blade B comprises a pin E, retaining ring F, and a washer G. In detail, the pin E is inserted in L direction, the washer G is inserted in R direction, and the retaining ring F is inserted into a groove 4 at the top of the pin for extraction prevention. The retaining ring F is made of an elastic steel material and provided with a notch 5 to hook a tool in disassembly for easy extraction. Also the notch 6 is formed symmetrically so that the bracket C can be installed even when the blade B is reversed. Thus the wiper rubber is not deformation hardened with the fins in bent condition and also can be taken care so that any deformation hardening may not be produced by removing a pin to remove the wiper rubber.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiper represented by an automobile, and more particularly to a wiper rubber and a fixing portion between a bracket and a blade.

[0002]

2. Description of the Related Art In a conventional wiper, as shown in FIGS. 6 and 7, a single row of fins at the tip of the wiper rubber (a) is reciprocally moved as shown in FIG. , And wipes off the adhered substances (K) on the glass surface (K).

Further, in FIGS. 6 and 9, the pin (e) for fixing the blade (a) to the bracket (c) is crimped and fastened with a bolt (ke) when it is attached to the arm (d). ing.

[0004]

In the conventional wiper, when the adhered substance (K) on the glass surface (K) is persistent, it can be dealt with by increasing the reciprocating speed of the arm (D), but the speed is limited. Yes, it takes time.

Then, as shown in FIG. 10, the fin acts on the adhered substance in a state where it licks, and the unevenness is left without being wiped off sufficiently.

Further, when the end of the wiper is used, the fin is always pressed against the glass surface (ki) and is bent to one side as shown in FIG. 11, and is hardened and deformed in this state.

In this case, the wiper rubber (a) may be periodically removed from the blade (a) and the mounting direction may be reversed by 180 ° for control, but the wiper rubber (a) may be removed from the blade (a). As shown in FIG. 12, there are several caulking portions (U), which is not a simple work and is generally not performed.

Therefore, when the various situations described above are conceivable, the wiping effect during one reciprocation of the wiper is reduced, and especially during driving, the driver's eyes are flickered and the visibility is hindered. It had a problem that it was dangerous because it led to a traffic accident.

An object of the present invention is to improve the wiping effect for one reciprocation and to make it easy to control so as not to harden and deform in a bent state even when it is not used for a long period of time.

[0010]

In order to achieve the above object, the wiper rubber in the present invention is provided with three rows of fins at the tip end, and double rows to operate in two rows.

Further, regarding the management of the wiper rubber described above, the blade to which the wiper rubber is attached is removed and managed, and for that purpose, the pin of the fixing portion between the bracket and the blade can be disassembled and reassembled. It has a different structure.

Then, the blade is made symmetrical so that it can be used even if the blade is inverted.

[0013]

The fact that the fins of the present invention work in two rows will be explained by taking a two-blade shave as an example. For example, a whisker that was missed by the first blade was slid by the second blade. Just like dropping it, the second row of fins will wipe off the deposits that were missed by the first row of fins without interruption.

When the wiper is not used, the blade is removed periodically, the fixing part is disassembled at one place so as not to be hardened and deformed in a state that the mounting direction is reversed by 180 ° and it is bent to one side, so that it is easily managed. it can.

[0015]

EXAMPLES Examples will be described with reference to the drawings. 1 and 2, the wiper rubber (A) is a fin (1).
The fins (2, which are the same as the fins (1)
3) is integrally molded so as to have a symmetrical shape. In the longitudinal direction, the fins (1, 2, 3) are molded over the entire length.

Further, in FIGS. 1, 3, and 4, the fixing portion of the bracket (C) and the blade (B) is composed of a pin (E), a retaining ring (F) and a washer (G). Inserts the pin (E) from the L direction, inserts the washer (G) from the R direction, and inserts the retaining ring (F) into the groove (4) at the tip of the pin to prevent the pin from slipping out. The snap ring (F) is made of an elastic steel material and is provided with a notch (5) so that the tool can be easily pulled out at the time of disassembly.

Further, the notch (6) has a symmetrical shape so that the bracket (C) can be attached even if the blade (B) is reversed.

[0018]

Since the present invention is configured as described above, it has the following effects.

In the double wiper rubber of the first aspect, as shown in FIG. 5, fins (1, 2,
Since 3) works in two rows, the wiping effect during one reciprocation is excellent.

Further, when the adhered matter (8) on the glass surface (7) is persistent, the adhered matter taken off by the fins (2) in the first row is wiped off with the fins (1) in the second row without interruption. This effect is sufficiently effective when the glass surface is frozen in winter, for example.

In the structure of the blade fixing portion according to the second aspect, when the wiper powder is used, the pin is simply pulled out so that the tip of the wiper rubber does not harden and deform when the fin is bent. It can be managed and works in a good condition when the wiper is activated, and the wiping effect is also improved.

Further, in the case of driving in the rain, visibility is deteriorated, and bad conditions such as the window glass being fogged and the road surface being slippery are likely to occur, resulting in a high degree of danger and a high possibility of an accident. Although the present invention does not reduce the possibility of accidents, at least the visibility within the working range of the wiper can be secured.
