Description

Device for detachable union of a wiper racket with a wiper arm.

State of the art

The invention relates to a joining device and a windshield wiper racket according to the type of independent claims. On the windshield wiper racket mentioned must guarantee the support element for the all of the cleaning field based on the racket of windshield wipers a uniform distribution of the pressure to tighten the wiper blade starting from wiper arm on the glass. By a curvature corresponding support element not loaded -that is if the windshield wiper does not line up on the glass - the wiper blade ends aligned during the operation of the wiper blade completely glass by the support element then tensioned towards the crystal, even if the radii and curvatures of crystals are altered of spherically curved cars in each position of the wiper racket. The curvature of the racket Windshield wiper has to be, then, something more pronounced than the more pronounced curvature and measurement in the cleaning field of the glass to be cleaned, the support element replaced by consequently the laborious construction of the support bracket with two transverse reinforcements positioned on the sheet Windshield wiper blade, elastic serving of spring rails, as practiced on snowshoes traditional windshield wiper (DE 1505394 A1). A racket of Windshield wiper with such a support element has to be easily connectable without getting lost in the arm of windshield wiper and has to be removable again from it.

To join a racket formed of this type with the wiper arm, has to be equipped with an element of particularly formed connection, with which it can be connected necessarily on the wiper arm. The wall surfaces of the joint element must ensure also a smooth guide to the windshield wiper racket, if it is deflected by the wiper arm transversely to its longitudinal extension on the glass to be cleaned, since it align to the guide surfaces of the wiper arm. As the generally curved windshield wiper of a automobile does not represent the section of a spherical surface, the windshield wiper racket must be adapted to the wiper arm during its cleaning movement constantly to the respective position and the course to the glass surface. Therefore the union is necessary articulated and easily movable, which allows a movement of swing around the axis of the articulated bolt between the arm of windshield wiper and wiper racket.

The invention starts from a joining device and a windshield wiper racket according to the type of claims 1 and 19. In a known device of this type (DE 19729862.1A1) both articulated bolts are provided in their wrapping surfaces respectively with two surfaces between yes opposite. That is why it is possible to incorporate the racket of Windshield wiper with these bolts on arm bearing necklines of windshield wipers, which are open at the edge in the distance of the bolt surface in tight introduction channels each. For the connection of the wiper blade with the wiper arm or for racket disassembly of windshield wiper arm has to turn certainly the wiper racket to a position transversely to the wiper arm extension by the axis of the articulated bolt, so that the bolts can be carried through the introduction channels in their bearing necklines and hold the wiper racket mounted in its position of operation on the glass on the wiper arm of such way that is not lost. In this case it is nevertheless necessary, of remove the wiper arm from the glass. In many cases However, such an arm movement is not possible of windshield wipers, since, for example, the arm of windshield wipers in their alignment position, which enables assembly process is located on the glass edge below a car body cover or you have to give up cost reasons for joint positioning foldable

Advantages of the invention

In the connection device according to the invention with the remarkable features of claim 1 have to join the adapter that shows the connection means on the side of the windshield wiper racket join the racket windshield wiper, first with the windshield wiper racket, of so that it belongs to the windshield wiper racket. The formation of a special joint between the wiper arm and the windshield wiper racket is therefore not necessary and the articulated joint functions and connection means are separated each other and therefore optimized without compromise. For the configuration of the clamping joint between the racket windshield wiper and windshield wiper arm have to incorporate only clamping and fitting agents positioned in the adapter with opposite clamping agents assigned to these of the wiper arm. Your configuration can take you to out for example in such a way that the union between the arm of windshield wiper and windshield wiper racket can be achieved by a sliding movement of the wiper blade on longitudinal direction of the wiper arm, not having lift the windscreen wiper arm or just very little glass.

A form of construction particularly narrow joint articulated between the wiper arm and the windshield wiper racket and therefore none disturbance of the view from the joint device of the automobile passenger enclosure then results if the distance between both wall surfaces of the connecting element is smaller than the width of the support element.

In this case a configuration particularly according to the finish of the invention both wall surfaces of the connection element are formed by the external surfaces in the T-foot of a component at least by parts in the cross section in the form of a T, whose head of T is assigned to the support element and linked with it.

A union of this type can be achieved by example favorably in costs such that the element connection is provided on its longitudinal edges apart each other's head T with protruding claw type, which grab the external longitudinal edges of the element of support.

Other technical finishing advantages result from the fact that the connection element has ready in the section transversal two essentially rectangular halves, which form together with the T foot aligned with each other on the angular side and its other angular side.

In this case it is convenient if both halves in The foot of T consists of a metal is joined in one piece.

In cases of special applications it can be particularly advantageous, if the connection element is made of a synthetic material, since then the bolts articulated can be included by models directly the element of  connection, if in another configuration of the invention you have the adapter a cross section essentially in the form of a U, whose both sides of U grab the foot of T of the connecting element of fixed form laterally, whose base of U covers the foot of T of the connecting element and is positioned on each of both sides of U an adaptation at its free ends open at the edge of slot type, whose slit ends form housing of bearings for articulated bolts, large surfaces result guides between the adapter that belongs to the racket windshield wiper and the connection element connected to the windshield wiper racket support, so that you get a free game union and that provides a good image of cleaning.

A securing of the adapter to the bolt articulated connection element, even if the arm is raised glass windshield wiper, results from the fact that the adapter is manufactured by an elastic synthetic material and that slot-type necklines have narrow places elastically expandable and limiting on the housing of bearings

For the improvement of the bearing guide articulated, the adapter is fitted on its outer side and with each other apart on its sides of U, with protruding neck type that surround the bearing housings.

With a view to an articulated union exempt from play and particularly narrow grabs the racket bra of windshield wiper arm wiper to adapter on their U sides with side vacations being positioned on the side skirts of the wiper blade racket open for protruding neck type adapter.

So you can't let go of the racket windscreen wiper unwantedly from the wiper arm or well of the windshield wiper arm holder, show the necklines a form of type L being open on the edge one side of L towards the windshield wiper racket support element and it extends one other side of L towards the free end of the arm of windshield wipers, the width of the necklines being adapted to the outer diameter of protruding adapter.

For a definitive and secure block in the operation of the wiper blade with the arm of the wiper is equipped with a tongue adapter elastically deviable against a restoring force, which a lace shoulder is formed, which is arranged transversely towards the windshield wiper racket and in a plane that is on the support element, being assigned to the lace shoulder an opposite lace shoulder fixed on the arm of windshield wiper and acting the opposite lace shoulder in conjunction with the lace shoulder, if the protruding neck type adapter at the ends closed from the other sides of L of the necklines on the walls Windshield wiper blade fastener sides.

An unintended drive of the tongue in the sense of an opening of the safety connection between the racket of windshield wipers and the windshield wiper arm is avoided, if the tongue is attached with at least one U side of the adapter and its side adjacent to its motor side of the wiper arm and if it also startles on the side of the racket wiper of the tongue the shoulder of lace, which is assigned the opposite shoulder of fixed lace on the arm of wiper washer.

In this case it is a form of execution nice in handling the invention, if the tongue is positioned at the U base of the adapter and extends towards the free end of the wiper arm, the opposite shoulder of lace on the front side of the arm Windshield wiper and tongue with its lace shoulder protrudes on the free end of the wiper arm.

To avoid a relative tilting movement e inconvenient for the articulated shaft between the arm of windshield wiper and adapter has been shown as convenient, if the adapter is provided with distance from the added parts of neck type at least in a U loop with a protruding side, to which a neckline provided on the side benches is assigned of the wiper blade holder.

For the protection of the articulated joint against fouling are positioned on protruding type neck with distance from the U sides of the adapter covers, which protrude over laterally protruding pieces of type shield.

From the previous explanations it results from consequently a whole series of characteristics, which contribute to the formation of an easily manageable, favorable articulated joint in costs and free of play between the wiper arm and the wiper racket. A known connection element of this type (DE 1972 98 64.8A1) shows only on one side of the foot of  T an articulated bolt for connection in the arm of wiper washer. It results, therefore, an articulated union positioned outside the longitudinal center axis of the racket windshield wiper, which can be shown as an inconvenience regarding the tightening pressure starting from the wiper arm and in certain crystal configurations. They also serve there both surfaces apart from the foot of T not as surfaces of  guide, which act together with opposite surfaces Windshield wiper arm corresponding during the process cleaning. The wiper blade guide will be occupied there only of unilateral annular fixation and small articulated bolt surface. If the item is set, however, according to the outstanding characteristics of the claim 20 additionally, the pressure of squeeze from the wiper arm evenly to both pivots and also an excellent racket guide of windshield wipers during cleaning operation.

Other additional configuration and advantages and embodiments of the invention are indicated in the following description of execution examples represented in the drawings relevant.

Description of the execution example

Figure 1 shows a side perspective of the free end of the wiper arm 10 actuated from its other end not shown, on which a racket of windshield wiper 12 through an articulated joint 13 of such so that it can swing in the direction of the double arrow 14. The wiper racket is an elastic support element 16 of longitudinally extended spring type band and curved on its band surface, on whose band surface 17 concave bottom and adjacent to the glass 20 is positioned a windshield wiper blade 18, an elastic rubber also extended longitudinally as a band parallel to the axis longitudinal. The surface to be cleaned of the car glass It is indicated in figure 1 by a line of dashes and dots. How line 20 must represent the steepest curvature of the glass surface can be seen clearly, that the curvature of the windshield wiper racket 12 still without load that aligns with its both ends to crystal 20 is more pronounced than the maximum curvature of the glass. For a clamping pressure that acts under the direction of arrow 22 on the arm of windshield wiper 10 aligns the windshield wiper racket with its wiper blade 18 along its entire length on the surface of the crystal 20, in this case a voltage is formed in the element of support 16 made of a metal, which deals with an alignment correct windshield wiper blade 18 throughout its entire length in the glass as well as a uniform distribution that the clamping pressure (arrow 22).

Since the glass generally spherical curved does not represent a section of a spherical surface, it has that the windshield wiper racket 12 can be adapted in front of the wiper arm 10 during its cleaning movement always to the respective position and surface development of the crystal That is why it is necessary to articulate easily movable between the wiper arm and the racket windshield wiper that allows oscillating movement (arrow double 14) by articulated shaft 24. The arrangement of the shaft articulated or oscillation is taken in this case in such a way which is directed transversely towards the longitudinal extension of the wiper arm 10 and transversely to the direction (arrow 22) of the clamping pressure. They have to explain themselves with more detail two examples of execution of an articulated joint of this type in what follows through figure 4 to 9 and from 10 to 13.

To the windshield wiper racket belongs still a connection element 26 (figures 2 and 3), which has a essentially T-shaped cross section. It has for consequently a foot of T 28 and a head of T 30, whose extension longitudinal is limited, however, to two sections comparablely short that is located with distance between them. In the songs longitudinal sections between them of the head of T 30 is positioned 32 protruding claw type, its function is Try later. as can be seen particularly in figure 3, in the example of execution the T-shape of the element of connection 26 in such a way that a sheet metal part is folded in such so that the foot of T 28 is formed by two sections of sheet 34 aligned with each other, which transforms into its further development angular on the head pieces of T 32. They result accordingly two halves positioned symmetrically with each other that are joined each other by the crease in the foot of T 28 of a piece, these two essentially rectangular halves that line each other's connecting element 26 therefore form with its one side angular 34 the foot of T 28 and the other angular sides proportion together the head of T 30. Both external surfaces 36 of the foot of T 28 apart from each other therefore meet a distance from each other that is smaller than the width 46 (figure 4) of the support element 16. The foot of T 28 of the connection element 26 is penetrated in its central longitudinal section in a perforation 27 of an articulated bolt 42 that is fixedly attached with the connecting element and whose both ends protrude in both sides of the foot of T 28 (figure 3) but it can also be thought to replace the articulated bolt or its both ends that protrude from the walls or external surfaces 36 on the side angular 34 or articulated pivot 23 by two short pivots and separated, which may be formed by you, for example by many procedures known to the expert for example the vessel positioning, stamping marks or flow warts by pressure, etc.

A first form of union execution articulated according to the invention between the wiper arm and the windshield wiper racket 12 is shown in figure 4 in A representation of explosion. The representation is limited in this case to the necessary areas of the windshield wiper racket 12 of the articulated joint 13. There it can also be seen as it is connected the connection element 26 with the support element 16 of the windshield wiper racket 12 the windshield wiper racket It has two longitudinal grooves as support element positioned parallel to each other on the sheet windshield wiper 18, in a longitudinal direction on its surface band curved spring rails 44 protruding at least the central longitudinal section with external edge rails of the longitudinal grooves the connecting element 27 positioned there covers from the external convex band surface 15 the element of support 16 with its protruding claw type 32 the strips of outer edges 45 protruding from the longitudinal grooves of the support rails 44, occupying a clamping force and / or welding points of a fixed connection between the rails of the springs 44 and connection element 26, the expert knows more clamping procedures This connection element 26 is by consequently part of the wiper racket. In observing the wiper blade in figure 4 se also clarifies that the distance 48 between both surfaces outer sides 36 (figure 3) is smaller than the width 46 of the support element 16.

At its free end 48 (figure 1) removed from its motor side, it is equipped with the wiper arm 10 of a windshield wiper racket 50. In the section Longitudinal shown in Figure 8 and in the observation simultaneous windshield wiper blade holder can be seen, that this has a U-shaped cross section. It has therefore in this area a base of U 52 and two sides of U or benches 54 positioned with distance and parallel to each other, in which are positioned a neckline 56 that has the shape of an L on one side of L 58 of neckline 56 is open at the edge at support element 16 (figure 4), while extending the other side from L 60 towards the free end of the wiper arm 10 or of windshield wiper blade holder 50. On the side the free end of the windshield wiper blade holder 50 neckline 56 extends with a distance from this one shoulder of dowries 62 in the residual space between the benches 34 of the fastener of the windshield wiper racket 50 (figure 8). Dowry Shoulder 62 is formed at the end as a directed angular continuation in 64 on the side of U 54 and points towards the free end of the windshield wiper racket in combination with figure 4 can be clearly seen, shown in figure 8 a half length of the wiper blade holder 50. As represents the longitudinal section plane a symmetrical plane is further clarifies that the other longitudinal half not shown in the windshield racket holder 50 is formed of image inverted with figure 8.

From figures 4 to 8 and 9 you can see the formation of an adapter 66, whereby the connection is made possible articulated wiper blade 12 with its element connection 26 on the wiper blade holder 50 of the wiper arm 10. In the observation of figure 9 it must be taken into account that the longitudinal section is also found in a symmetrical plane, so that the other half longitudinal, which can be seen from figures 4 and 5, and is missing, it has an inverted image formation and that corresponds to the Figure 9. In addition, the mentioned figures show a configuration U-shaped adapter 66. The distance 68 (figure 5) between its both sides of U 70 is selected in such a way that it results in a easily movable guide but free from adapter play on the foot of T 28 of connection element 26, if this is carried in its work position. In this working position it covers the base of U 72 the foot of T 28 of the connecting element 26. In each of both U 70 sides of adapter 66 are positioned congruently with each other 74 slot-type necklines open at the edge towards the free ends of the sides of U being formed at the ends of bearing housing grooves 76 for bolts articulated 42 of the connecting element 26. To ensure a secure attachment of the adapter 66 on the bolt articulated 42, show the grooves of slot type 74 in the area of the accommodation 76 narrow places 78 elastically expandable. Slot-type necklines 74 form introduction channels, over which can be incorporated type articulated bolts pivot 42 in its bearing housings 76. The expandability of narrow places 78 is achieved in the example of execution of such that the adapter 66 is made of a material elastic synthetic. As figures 5 and 6 particularly teach they are positioned on the outer sides apart from each other U 70 sides of adapter 66, added neck type 80 parts, surrounding the bearing housings over at least 180º of ring shape (figure 6). The diameter 82 of the added pieces of Type 80 is adapted to the width 57 of the neckline 56. In the Free ends of the 80 type neck-added pieces are positioned - as seen particularly from Figures 4 and 5- covers 84 protruding laterally over the added parts 80 and they are shield type. The distance 86 between the sides exterior and sides of U 70 and adjacent interior walls to these of the curvatures 84 are adapted to the thickness 55 (figure 8) of the benches 54 of the racket holder windshield wiper 50. At its end adjacent to the driving end of the wiper arm 10 is equipped with adapter 66 of a tongue 88 joined with this in one piece and elastically deflectable against a restoring force of blade type, whose surfaces of sheet are placed approximately parallel to the plane of the support element 16. On the surface of sheets adjacent to the U 72 base of adapter 76 shows tongue 88 an outstanding 90 tooth type, on whose side away from the adapter body a lace shoulder 92 is formed. The lace shoulder 92 is extends transversely to the wiper blade 10 and in a plane that is on the support element 16.

For the preparation of the racket joint windshield wiper 12 with windshield wiper arm 10 is applied firstly the adapter 66 on the component 26. In this case of apply adapter 66 in the direction of arrow 67 on the foot of T 28 of element 26, the articulated bolts 42 of type arriving pivots (figure 6) after passing the narrow place 78 in its bearing housing 76. In this mounting position you can swing the adapter 66 by the angular measure necessary to ensure the cleaning work of the wiper blade around articulated shaft 24, which is formed by bolts articulated 42 in the direction of the double arrow 14 (figure 1). He adapter 66 now forms a part of the racket windshield wiper 12. For connection on the arm windshield wiper 10 moves the windshield wiper racket including adapter 66 against arrow 67 (figure 4) towards the windshield wiper racket holder 50 of such way, that adapter 66 arrives between the sides of U or the 54 of the windshield wiper blade holder 50. On In this case, the 80 pieces of the neck type are introduced in the necklines 56 of the wiper blade holder 50, submerging the benches 54 between the sides of U 70 of the adapter 66 and the shield-type covers 84 of the added pieces 80. Yes mounting movement directed against the arrow 67 by the L-shaped figure of the neckline 76, the windshield wiper racket in the direction of arrow 94 (figure 4) towards the free end 48 of the racket holder windshield wiper 50, until the added parts 80 are aligned in neck shape at the closed end of the other side of L 60 of the neckline 56. In this terminal or working position now reached of the windshield wiper blade 12 on the windshield wiper arm 10 spring the tongue 88 deflected in its position of output to the support element 16 of the racket windshield wiper 12 during the process in the direction of the arrow 87 by continuation 64 towards the support element 16, acting together the lace shoulder 92 formed in the protrusion 90 with the shoulder shoulder 62 in the continuation. Language 88 is found in this case protected below the arm of wiper washer. To guarantee the work position exempt from regular free play of the wiper blade 12 on the wiper arm 10, a careful adaptation of the distance 96 between the articulated shaft 24 and the abutment man 62 on continuation 64 of the remote wiper arm 98 between the articulated shaft 24 and the lace shoulder 92 of the adapter 66. If you have to disassemble the racket windshield wiper arm wiper, has to deviate only tongue 88 in the direction of arrow 87 to such an extent, that releases the lace shoulder 92 butt shoulder 62. Then you can  turn off the windshield wiper racket first against the direction of the arrow 94 and can then be removed in the direction of arrow 67 on the wiper arm 10.

In the other embodiment of the invention, represented in figures 10 through 13 corresponds to both the formation of the wiper arm 110 or its fastener wiper racket and adapter formation 166 essentially to the formation of the windshield wiper fastener 50 or either from adapter 66 to the first embodiment above described That's why all the configurations are called there described and adapted and altered with a reference number which is 100 higher than the reference numbers of the first way of execution. The description of the second is also limited exemplary embodiment of the invention essentially to the details, in which the second form of execution of the first deviates manner of execution already described.

So you have the wiper arm on your transverse wall 111 at its free end an opening 200 (figure 10), whereby the base of U 152 and zones ends Partial U-sides or benches 154 with a surface front 162 and the front surface 162 of the U base forms a dowry shoulder on the side of the wiper arm. This dowry shoulder 162 replaces dowry shoulder 62 according to the first way of execution. They are also positioned on the sides of U 154 of the windshield wiper blade holder 150 necklines 156, that also have a configuration in the form of an L and that therefore show two sides of L 158 and 160. On the side away from the front surface 162 has the bra windshield wiper 150 on its sides of U 150 respectively a slot open at edge 202, which extends in the direction wiper arm length and therefore also in direction on the other side of L 160. The opening of the Slots 202 is removed from the front surface 162. Instead of language 88 is positioned in the first form of execution, in the adapter 166 an elastic spring tongue and deviable against a restoring force 204 at the end of adapter 166, which it is placed after the installation of the wiper blade 12 on the wiper arm in the free end interval of the wiper arm 110. It is positioned as extension at the base of U 172 of adapter 166 made of a elastic synthetic material on its upper tongue surface adjacent to the base of U 162 is an outstanding piece tooth type 190 extending transversely to the extension length of the wiper arm 110 and in which it is formed in a plane that is on the support element a shoulder lacy 192, pointing out the free end 148 of the arm windshield wiper 110. The adapter is also fitted in both U 170 sides of protruding ribbons 206, which are assigned to slots 202 on the sides of U 154 and that are positioned on the outer surfaces apart from each other U 170 sides.

For mounting the wiper blade on the wiper arm proceed as follows: firstly, the adapter 166 is applied in the manner already described direction of arrow 208 on connection element 26, which corresponds to the connection element already described. In this case it arrives the foot of T 28 of element 26 between the sides of U 170 of the adapter 166 and pivot type articulated bolts 42 penetrate into slot-type necklines 174 on the sides of U 170 (figure 13) until narrow places arrive 178 accommodations of bearings 176. In this position the adapter 166 is held by the effect of the elastically expandable narrow places of fixed form on wiper racket 12 in which represented in figure 10, however, only the element of connection 26. In this case the setting is configured, as well as in the embodiment already described in adapter 166, that the adapter can be tilted in front of the connection element 26 and the shaft articulated formed by articulated bolt 42 in the direction of the double arrow 14 in figure 1. Adapter 166 now belongs to the windshield wiper racket, which can now be attached without difficulties with the wiper arm 110 or with the Wiper arm holder 150 detachable. For that the windshield wiper racket is assembled in the manner already described in this way with the racket holder of 150 windshield wipers arriving at the added neck type parts 180 on the L-shaped necklines 156. If this stage is reached assembly the intermediate position already described, the racket of windshield wiper in the direction of arrow 194 (figure 10), up to that collide the neck 180 protruding pieces on the edge terminal on the other side of L 160. In this position the tongue comes out deflected during the incorporation of adapter 166 in the fastener of wiper racket 150 in the direction of the arrow 191 by the base of U 152 in the direction of arrow 108 of the opening 200 of the wiper blade holder 150 and back by the spring against the direction of arrow 191 in its starting position, where lace shoulder 192 of the protruding part 190 with the front surface 162 of the fastener of the wiper arm 150 free of play. Also in this way of execution it is important that the distance 196 of the axis articulated 24 to the front surface 162 of the fastener of the windshield wiper blade is adjusted exactly to the distance 198 from articulated shaft 24 to lace shoulder 192 overhang 190 of adapter 166. During the movement of mounting in the direction of the arrow 194 then also penetrate simultaneously protruding strips 206 of the adapter strip 166 in the slot-type necklines 202 assigned to them in the 154 sides of the wiper blade holder and consequently secure the adapter 166 against a movement unwanted pendulum on the windshield wiper bracket 150 around the pendulum axis 24 the disassembly of the racket Windshield wiper arm wiper is carried out of in the manner already indicated, that language 204 has deviated both in direction of arrow 191, figure 11, that the front surface 162 serving as, bra dowry shoulder of the wiper blade 150.

Both examples of execution have in common that is supported by the two articulated pivot type butts a adapter 66 or 166 pendular along its longitudinal axes 24 which show means for connection in the racket holder of windshield wiper 50 or 150 of the windshield wiper arm 10. The necessary pendular movement between the wiper arm and the windshield wiper racket is then carried out between the adapter 26 fitted to the wiper arm and the element connection 26.
