    Wiper blades for cleaning vehicle windscreens
    [2] Known windscreen wipers include a wiper arm consisting of a fixed part fixed to a drive shaft, a joint part engaged with the fixed part via a joint link, and a wiper rod securely connected to the joint part. The windscreen wiper also includes a wiper blade having a carrier bracket system and a wiper strip held by the system. The wiper blade is linked to the wiper arm, wherein the hooked end of the wiper rod not only engages between the two sidewalls of the carrier bracket system but also includes a hinge bolt. The joint thus configured guides the wiper blade together with the wiper strip to the windscreen of the vehicle, whereby the joint part and carrier bracket system can be configured to adjust the wiper strip according to the windscreen curvature of the vehicle. The adhesion required to adhere the wiper strip to the windscreen of the vehicle can be obtained using at least one tension spring which pretensions the stationary part and the joint part together with the wiper rod via the joint link.
    [3] The wiper strip is composed of, for example, an elastomer such as natural or synthetic rubber or ethylene propylene. The wiper strip has a head strip that engages a wiper lip seated on the windscreen to be cleaned via a swing bar. The wiper lip always has an advantageous angle with respect to the windscreen since the wiper lip is diverted in the opposite direction at the turning point of the wiping motion by constructing the swing bar. When the windscreen wiper is activated, the wiper strip and the wiper lip slide on the windscreen of the vehicle, where they are aged by friction between the wiper lip and the windscreen. In addition, the wiper strip is subjected to ambient conditions such as temperature changes, ultraviolet light, brine, exhaust gases and the like, which tend to wear parts more quickly as well as prematurely age the parts.
    [4] In order to produce a wiper strip that can remain intact even in new vehicles, it is known that the wiper strip is covered with a protective profile before the vehicle leaves the factory. After the vehicle is delivered to the buyer, the protection profile is removed. However, if the windscreen is soiled in the vehicle removal process, the shipping process, or the like, or the view is obstructed by rain, the vehicle wiper system cannot perform the function for cleaning the windscreen. As a result, the protection profile is hardened and only part of it touches the windscreen.
    [5] DE 30 05 965 A1 discloses a method in which a flexible band having a longitudinal edge is fixed on a protective profile on the side facing the windscreen. This protective profile consists of hardened PVC and the band consists of softened PVC. Thus, when the wiper is actuated, the band is generally changed over the entire length of the wiper blade, thereby adjusting within a certain range with respect to the curvature of the windscreen at the entire length. Since the band is used as a wiper lip, the wiper system can clean the windscreen without the wiper strip of the wiper blades deteriorating during the cleaning process.
    [6] It is also known to weld the protective profile laterally in order to stably secure the protective profile to the wiper blades and to protect the wiper strip from the surrounding environment. For this purpose, the protective profile is heated at the front and pressed against the plate. The plate is a plate of material capable of welding the protective profile. In this way, if only one front side is welded prior to assembly and the second front side is welded later, the protective profile is separated from the wiper strip and the protective profile is cut upon disassembly.
    [1] The present invention relates to a wiper blade according to the preamble of claim 1.

    [7] According to the invention, the protective profile is closed with a cover on at least one end along the longitudinal direction, by which the protective profile can be opened and closed multiple times for assembly and disassembly. The cover can be inserted on the protective profile and can be detachably coupled to the protective profile in the form of a forced fit and a shape fit. In addition, the cover is reliably coupled with the protective profile and can be fixed in the closed and open position by means of retaining means, for example a cover or a straight line that reliably engages with the protective profile by a joint, for example, via a rotary motion. And a cover engaged with the protective profile by the rail through the movement.
    [8] On the other hand, the use of the cover according to the invention allows for simple and inexpensive assembly and disassembly, where the protective profile can preferably be closed on both sides without breaking the protective profile during assembly. The protection profile can be used repeatedly for assembly purposes. In addition, the cover may also be used in combination with other closure members, such as a welded front, etc., but it is preferable to close the protective profile with two covers. In one embodiment, the protective profile is closed with two covers disposed on the wiper strip. This protection profile is protected on both sides from the surrounding environment, reliably fixed on the wiper strip, and fixed in both longitudinal directions, thus preventing damage as well as friction between the protective rail and the wiper strip when the wiper is driven. .
    [9] By using a cover having two closed surfaces and an axis of symmetry in the transverse direction with respect to the longitudinal direction, at least two methods are possible in the cover assembly process, more specifically, assembly in the form of 180 ° rotation around the axis of symmetry. The assembly is simple and preferably the two closing surfaces can also be used as assembly grips.
    [10] In another embodiment, the protective profile is closed with an inwardly inclined protrusion at the at least one end towards the longitudinal direction along the transverse to the longitudinal direction. The protrusions can be installed simply and quickly, for example in a metal profile using a kind of punch and in a synthetic profile it can be installed as a heating source, particularly preferably an ultrasonic source. A protective profile with a gap in which a wiper strip with a wiper lip between the protrusion formed on the first side wall and the second side wall can be guided during assembly and disassembly can already be closed on both sides by the two protrusions in the assembly process. As a result, the step of assembling the protective profile to the wiper can be omitted, so that the assembly can be made easily and inexpensively in a short time. For example, additional structures such as covers can be omitted. In addition, the construction of the protective profile, which is closed at both sides, allows for damage-free assembly. The protection profile may be used a plurality of times, thereby protecting the environment and saving energy.
    [11] To facilitate assembly of the protective profile on the wiper strip, the protrusions include an inclined surface that is inclined inward with respect to the front side in the longitudinal direction, which allows the wiper lip of the wiper strip to be adjusted in the gap direction during assembly. The protrusion also has a second inclined surface that is inclined outward along the longitudinal direction, which holds the protective profile firmly on the wiper strip while the wiper is in operation, not only facilitating breakage-free disassembly, but also of the wiper strip. Adjust the wiper lip in the gap.
    [12] Closing operations using protrusions can be used in combination with other closure members, for example in combination with covers or welded facades. However, it is preferable that the protective profile is closed with protrusions at both fronts. In order to fix the protective profile in both longitudinal directions, the distance between the protrusions is preferably configured equal to the length of the wiper strip. This prevents friction and breakage between the windscreen and the wiper strips.
    [13] Other advantages are described with the accompanying drawings, which illustrate embodiments of the invention. In addition, the drawings, embodiments, and claims contain various features in combination, and those skilled in the art can, individually, contemplate each feature as well as other meaningful combinations.
    [28] 1 shows a carrier bracket system 10 consisting of a main bracket 64, an intermediate bracket 66 hinged to the main bracket, and a crow bracket 68, 70 linked to both ends of the intermediate bracket. A portion of the wiper blade having is shown. The wiper strip 12 is fixed to the retaining crow 72 of the crow brackets 68, 70. The wiper strip is wrapped with a protective profile 14 that secures the wiper component 74 to the windscreen to protect the wiper strip 12 from heat or other surroundings before selling it to the purchaser.
    [29] The protective profile 14 is made of an elastic synthetic resin such as polypropylene and can be adjusted according to the curvature of the windscreen through elastic deformation. The protective profile 14 has a hollow profile with two side walls 76, 78 extending longitudinally and enclosing the wiper strip 12, which hollow protrusions 80, 82. ), Which is fixed to the wiper strip 12 in the region of the swing bar 84 and gradually tapering from the wiper strip 12 in the direction of the windscreen (FIG. 2). Each sidewall 76, 78 includes two turning points 86, 88, 90, 92 in which elastic deformations can be made. If possible, it may be configured in the form of, for example, corrugated sidewalls in order to construct many turning points. In addition, elastic deformation can be increased by forming a rounded bulb-shaped profile with respect to the windscreen, and by setting the wall thickness 94 to 0.8 mm or less. The preferred wall thickness 94 is 0.6 mm in the illustrated embodiment but may be set differently.
    [30] FIG. 3 is an enlarged view of part III of FIG. 1. Here, the protection profile 14 is closed with covers 16 and 18 of synthetic material at both ends in the longitudinal directions 37 and 40. The covers 16, 18 are inserted on the protective profile 14 and the three fins 98, 100, 102 arranged on the inner surface 96 of the protective profile 14 and the cover surface of the protective profile 14 ( One band 106 disposed on 104 is detachably coupled in the form of a forced fit (FIGS. 4, 5, 6). To facilitate assembly of the cover 16, 18, or to insert on the protective profile 14, the band 106 and the pins 98, 100, 102 are provided with faces 108, 110, 112, 114. Has The covers 16, 18 can be separated from the protective profile 14.
    [31] The protective profile 14 can be reliably fixed on the wiper blade to protect the wiper strip 12 from the surrounding environment as well as to be easily assembled or disassembled by the covers 16 and 18. In particular, the protective profile 14 which is closed on both sides can be used again after disassembly using at least one cover 16, 18. In order to prevent the protective profile 14 from being lifted from the wiper strip 12 when the wiper is in operation, and to prevent friction and wear of the protective profile and the wiper strip, the covers 16 and 18 have a wiper strip ( A band 106 is disposed on 12 to secure the protection profile in both longitudinal directions 38, 40 (FIGS. 1, 3). The elasticity of the protective profile 14 is hardly affected by the covers 16, 18 which are only partially disposed on the protective profile 14. The side walls 76 and 78 are bent inward regardless of the cover 16 and 18 when the protective profile 14 elastically deforms.
    [32] 7, 8 and 9 show the cover 20, which is covered by the pins 116, 118, 120, 122 as well as the holes 124, 126 as well as the side walls 42 of the protective profile 22. 130 is detachably fixed in a forced fit form (FIGS. 10 and 11). The cover 20 includes an axis of symmetry 26 transverse to the longitudinal directions 38, 40 and an axis of symmetry 128 perpendicular to the longitudinal directions 38, 40, the protective profile 22 of the protective profile 22. Two closed surfaces 28, 30 according to the cross-sectional shape. Since the cover 20 rotates 180 ° about the symmetry axes 26 and 128, respectively, the cover 20 may be assembled in various forms. Assembly is easy and the two closing surfaces 28, 30 protruding from the protective profile 22 can preferably be used as disassembly grips.
    [33] The protective profile 22 can be closed by the cover 20 in the longitudinal direction 40 and by the projections 32 transverse to the longitudinal directions 38, 40 on the second end in the longitudinal direction 38. It is closed (FIG. 10). The protective profile 22 is made of synthetic resin and the protrusions 32 are installed by the ultrasonic source at the side walls 42 and protrude up to the second side walls 13.
    [34] 12, 13 and 14 show a protective profile 24 which is closed with projections 34 and 36 on both ends in the longitudinal directions 38 and 40, with the projections for the longitudinal directions 38 and 40. FIG. It is set inward along the transverse direction and is installed on the side wall 44. The protrusions 34 and 36 are molded to the side wall 44 by an ultrasonic source or ultrasonic sonde in the profile 24 of the synthetic resin material.
    [35] The length 50 of the protrusion 34 is determined at a position away from the windscreen so that a substantially constant gap 48 can be formed between the protrusion 34 and the second side wall 46, which causes the wiper lip. When assembling or disassembling (132: FIG. 2), the wiper strip 12 can be guided without being broken (FIGS. 13 and 14). The protrusion 34 includes an inclined first inclined surface 56 that is tapered in the transverse direction with respect to the longitudinal directions 38 and 40 and inclined inward 30 o along the longitudinal direction 40 with respect to the front face 54. In this case, the inclined surface of the wiper lip 132 of the wiper strip 12 is adjusted in the direction of the gap 48 during assembly to facilitate assembly (FIG. 14). The protrusion 34 also includes a second inclined surface 58 that is inclined outwardly along the longitudinal direction 38 by 10 o with respect to the inner surface toward the longitudinal direction 40, the inclined surface having a protective profile (when the wiper drives). 24) is firmly held on the wiper strip 12 to facilitate damage-free disassembly.
    [36] The protrusion 36 has the same shape as the protrusion 34 having an inclined surface with respect to the front surface 52 and an inclined surface with respect to the inner surface. The protrusions 34, 36 are spaced apart from each other at a distance 60 equal to the length 62 of the wiper strip 12 (FIGS. 12, 1). This structure prevents friction between the protective profile 24 and the wiper strip 12 and the protective profile 24 can be repeatedly fixed against the wiper blade. In addition, the wiper strip 12 can be protected against the surrounding environment. The protrusions 34, 36 extend over a small circumferential portion of the protective profile 24, with the result that the elastic deformation is hardly affected.
