Definitions
- the invention relates to an adapter for adapting a main bracket of a wiper blade to the coupling section of a wiper arm of a wiper device for flat wiper blades.
- the flat wiper blades are distinguished by the fact that they do not have a cascade-type bracket system, but rather one or more, correspondingly curved elastic support elements that extend in the longitudinal direction of the wiper blade. Under the contact pressure, such a wiper blade with its wiper lip lies against the surface of the window to be wiped over its entire length. In the process, a tension builds up in the elastic support element, which ensures that the wiper strip lies properly against the window over its entire length.
- the present invention is therefore based on the object to provide a remedy in the event that proper wiping of the panes is ensured even when flat wiper blades with a specially designed fastening section are not available.
- an adapter with an insertion receptacle for inserting an axle bolt extending transversely to the wiper blade longitudinal axis between the side walls of the main bracket, with an insertion opening having a cylinder recess for lateral insertion and for largely free of play receiving an articulated bolt which extends transversely to the wiper blade longitudinal axis of the coupling section, a first contact section being provided in the area of the insertion opening for contacting the area of the coupling section holding the hinge pin, and the adapter having a second contact section arranged on the side facing away from the insertion opening for contacting the stop of the adapter in the assembled state at least in sections comprehensive approach of the coupling section.
- the adapter is plugged onto the axle bolt of the main bracket from above, that is to say from the side facing away from the windshield, with its transversely slotted insertion receptacle.
- the plug-in receptacle advantageously engages with the axle bolt.
- first and / or the second contact section is raised in the transverse direction in such a way that the respective side wall of the main bracket is protruded in the assembled state. Defined points of contact between the adapter and the coupling section are thereby realized.
- the first contact section is preferably arranged at a distance from the second contact section in the longitudinal direction of the wiper blade.
- the cylinder cutout which serves to receive the hinge pin of the wiper arm, can be designed, for example, as a through hole or as a blind hole.
- the use of a blind hole contributes to assembly security insofar as the hinge pin of the wiper arm can only be inserted into the cylinder recess in one direction. If a blind hole is provided as a cylinder recess, it is advantageous to provide a ventilation opening in the bottom region of the blind hole. This can dry out rainwater, for example, that penetrates into the blind hole.
- the cylinder recess is advantageously arranged above the insertion receptacle.
- the axis of the The cylinder recess and the axis of the insertion receptacle preferably run parallel to one another.
- a secure arrangement of the adapter is obtained if the adapter is arranged at least in sections between the side walls or in the hanging box of the main bracket in the state mounted on the main bracket.
- the second contact section of the adapter at least partially has a cheek which at least partially encompasses a side wall of the main bracket in the assembled state. In this way, lateral forces acting on the wiper blade are safely diverted into the wiper arm.
- the contact section is L-shaped or U-shaped in cross section.
- the width of the contact section which extends in the transverse direction, in the assembled state, largely engages positively with the attachment and stop of the coupling section of the wiper arm becomes.
- the adapter In the assembled state, the adapter can either be held in a rotationally fixed manner on the main bracket or in a rotationally fixed manner on the wiper arm. If the adapter is held on the wiper arm in a rotationally fixed manner, this has the advantage that wear occurs on the moving parts between the wiper blade and the adapter. Wear parts are therefore replacement parts. The coupling section of the wiper arm is then not subject to wear.
- the adapter has at least one latching section for latching with the main bracket or the extension or the stop of the wiper arm. It is advantageous if the latching section or the latching sections are arranged on the second contact section or on at least one cheek of the contact section.
- the latching section or the latching sections are arranged at the free end or the free ends of the cheeks of the corresponding contact section.
- an advantageous adapter is obtained when the adapter has a circumferential edge on its upper side which, when mounted on the main bracket, preferably completely covers a hanging box on the main bracket. This prevents dirt or leaves from entering the hanging box and negatively influencing the functioning of the wiper blade.
- Figure 1 shows an adapter according to the invention in the assembled state in plan view
- Figure 2 shows a section along the line II
- Figure 3 shows a section along the line III; and 4 shows a section corresponding to FIG. 2 through a second embodiment of an adapter according to the invention.
- FIG. 1 shows an adapter 10 according to the invention, which is arranged in a hanging box 12 between two side walls 14 and 16 of a main bracket 18 of a cascade-shaped bracket wiper blade, not shown.
- the adapter 10 has a slotted plug-in receptacle 20 extending in the transverse direction of the wiper blade for introducing an axle bolt 22 of the main bracket 18, which also extends in the transverse direction of the wiper blade.
- the axle pin 22 extends between the two side walls 14 and 16 and is attached to them.
- the insertion receptacles 20 are plugged onto the axle bolts 22 from above.
- the insertion receptacle 20 is in this case formed by elastically deformable insertion sections 24.
- the distance a between the two side walls 14 and 16 of the main bracket 18 is slightly larger than the width b of the section of the adapter element 10 located in the hanging box, so that the adapter element 10 can be inserted between the two side walls 14, 16.
- the adapter 10 also has a cylinder recess 26 with an opening 27 for receiving a hinge pin 28 of the coupling section 30 of a wiper arm 32.
- the cylinder recess 26 is designed as a blind hole.
- the coupling section 30 of the wiper arm 32 essentially corresponds to the coupling section known from WO 00/73113 AI for the arrangement of flat wiper blades.
- the adapter 10 only partially has a cheek 36 resting against the side wall 16.
- a longitudinal groove 38 is provided, into which the upper edge of the side wall 16 engages.
- the adapter 10 has in the region of the insertion opening 27 a first contact section 44 which is raised in the transverse direction and serves to contact the wall 42 of the coupling section 30 holding the joint pin 28.
- the contact section 44 projects beyond the side wall 14 of the main bracket 18 in the transverse direction. This ensures that the wall 42 of the coupling section 30 can come into contact with the contact section 44 without being adversely affected by the main bracket 18 or its side wall 14.
- the adapter 10 has a second contact section 46 on its side facing away from the first contact section 44. This contact section projecting beyond the side wall 16 of the main bracket 18 in the transverse direction is provided in the assembled state of the adapter 10 for contacting the stop 48 of an attachment 50 which at least in sections overlaps the adapter 10 and has an L-shaped cross section.
- the contact section 44 is therefore advantageously largely free of play against the wall 42 and the contact section 46 against the stop 48.
- the first contact section 44 is arranged in the longitudinal direction at a distance from the second contact section 46, as is clear from FIG. 1. Due to the largely play-free abutment of the contact sections 44, 46 on the coupling section 30 of the wiper arm 32, transverse forces acting on the wiper blade can be derived into the wiper arm 32. A detachment of the wiper blade from the wiper arm 32 is not possible due to the stop 48, which extends largely perpendicular to the window surface. In the embodiment shown in FIG.
- the adapter is identified by the reference number 100, the components corresponding to the adapter 10 being provided with the same reference numbers.
- the adapter 100 has a circumferential edge 60 on its upper side, which at least in sections covers the hanging box 12 in the assembled state.
- the adapter 100 also provides a cheek 62 in the region of its second contact section 46, which abuts the outside of the side wall 16.
- the side of the cheek 62 facing away from the side wall 16 serves as a contact section 64 for contacting a stop 48.
- the adapter engages around a side wall of the main bracket facing the coupling section.
- the adapter can be mirror-symmetrical to its central plane running in the longitudinal direction.
- the adapter 10 is either non-rotatably connected to the main bracket 18 or to the coupling section 30 of the wiper arm 32. It is advantageous if the adapter 10 is arranged on the coupling section 30 in a rotationally fixed manner. The relative movement between the wiper blade and the wiper arm then takes place between the axle pin 22 or the side walls 14, 16 and the adapter 10. When the wiper blade is renewed, the adapter 10 is also renewed; consequently, no signs of wear occur at the coupling section 30 of the wiper arm 32.
