Description

Vehicle Wiper

The utility model relates to the automotive industry and, in

in particular to glass cleaning products.

Known wipers containing brush holders with paws, a scraper in the form of a profiled part made of elastomer and at least one reinforcing plate made with a protrusion and facing it were supported for paws connected to the scraper and connected to the brush holder by paws, one of them fixed on the scraper with stops, and the other is made longitudinally movable (US Pat. No. 3541629 class. 15-250.42)

Known wipers do not have sufficient rigidity, and therefore, sufficient cleaning efficiency. They are not economical to manufacture and assemble.

The closest analogue of the proposed utility model is a wiper containing a profiled scraper made of elastomeric material, a reinforcing plate located in the longitudinal recess of the scraper, a brush holder consisting of a central part and two movable rockers at the edges. Each of the rocker arms is equipped with a pair of legs covering the scraper, one of the legs in the pair being fixed, and the second

MKI BGOS 1/38

has some freedom of longitudinal movement (see USSR Patent No. 1195897 according to class BGOS, 1/38).

The manufacture and assembly of such wipers is not economical. The service life is not long, because conventional anti-corrosive coatings quickly deteriorate, two plates become rusty, the adhesion of road dirt increases, they cease to be elastic in the grooves. In addition, both plates are not interconnected, which complicates the assembly of the scraper. During operation, the plates fall out of the grooves - at least one,

The purpose of this utility model is to manufacture a wiper blade in which the ratio of the thicknesses a and widths in (Figs. 2, 3) of one reinforcing plate provide sufficient structural rigidity and flexibility at the same time as the wiper operates even under conditions of increased load on it in winter period. Protection from the atmospheric effects of the reinforcing plate in one embodiment is provided by treating it with an anti-corrosion coating with a high resistance coating and full usability in profiled recesses, and in the second embodiment due to its complete isolation in the longitudinal hole of the scraper.

An increase in the rigidity of the scraper structure in this way allows increasing its size by 15-20% and eliminates the possibility of the plates falling out of the scraper.

(elastic material, for example, selicon, rubber, etc.), in the longitudinal recesses of which are placed flush reinforcing plate "and -shaped, curved in the plane of its width" in (Fig.2).

In another embodiment, a reinforcing plate of rectangular cross section is inserted into the corresponding hole of the elastomeric scraper either during manufacture or pressing or after manufacture.

In more detail, the device of the wiper and its modifications are shown in the drawings:

figure 1 - General view of the wiper;

figure 2 is a plan view of the "and -shaped plate, the first embodiment,

figure 3 - the first embodiment of the scraper (section aa) in figure 1,

figure 4 - section bB in figure 1,

figure 5 is an elongated part of the scraper (section bb in figure 1),

on figb is a plan view of a rectangular plate, a second embodiment,

in Fig. 7 is a second embodiment of a scraper, section AA in Fig. 1.

The wiper device includes a scraper 1 (Fig. 1), a reinforcing plate 2, a brush holder 3, rocker arms 4 and 5, movably fixed to the ends of the brush holder 3. Each of the rocker arms 4 and 5 is equipped with a pair of legs 6, 7 and 8, 9, respectively.

The reinforcing plate 2 (Fig. 1, 2, 3, 4, 5) is made of a strip of metal "and -shaped, curved in the plane of its width" in (Fig.2). The width of the plate is selected so that it does not deform in the longitudinal recesses 10 and 11 of the scraper 1, and the length exceeds the length “L of the brush holder 3 with rocker arms 4 and 5. A reinforcing plate 2 is installed in the recesses 10 and 11 of the scraper 1 from two sides to the full drowning in them. Those. the height of the said grooves corresponds to the thickness of the plate 2. The distance between the parallel planes of the plate 2 corresponds to the distance between the profiled recesses 10 and 11 of the scraper 1.

The increase in the length of the “1 reinforcing plate El 2 together with the length of the scraper 1 is made from the side of its curved part and is 15-20% of the entire length of the scraper.

In another embodiment (Fig.6, 7), the scraper 1 is also made of elastomeric profiled material with a longitudinal technological hole 12 and a longitudinal hole 13, the cross section of which corresponds to the cross section of the reinforcing plate 14.

The reinforcing plate 14 can be inserted into the inside of the scraper 1 in the second embodiment of the plate both during manufacturing-pressing and separately, after pressing. For free movement - sliding plate, it is passed through a paraffin liquid.

This method of reinforcing the scraper 1 increases its service life, increases the efficiency of manufacturing, not

requires anti-corrosion coating of the plate 14, because she

it is isolated from external atmospheric influences. Ease of replacement of the elastomeric scraper is ensured in case of wear.

The ratio of the width and thickness dimensions of the reinforcing plate 2 or 14 in both versions provides sufficient structural rigidity and its flexibility in the operation of the wiper even under conditions of increased load for it in the winter.

The complete recessibility of the “and -shaped plate in the profiled recesses of the scraper in the first embodiment and the insulation of the reinforcing plate in the hole of the scraper in the second embodiment preclude any possibility of them falling out of the scraper, so increasing their length“ 1 together with the scraper increases the reliability of the wiper and ensures comfortable operation by increasing the viewing area.
