Description

Technical Field

[0001] The present invention relates to a scroll bearing for a scroll that bears a scroll web in a vehicle rolling blind device, wherein the scroll bearing has a guiding unit that guides a scroll edge of the unrolled scroll web to a guide rail connected to the scroll bearing. Furthermore, the present invention also relates to an injection molding tool for injection molding such a scroll bearing. Background Art

[0002] A scroll bearing for a scroll of such a vehicle rolling blind device is disclosed by DE 20 2018 100 220 U1. A guiding unit in the form of a guiding element guides a side edge of the scroll web onto a guide rail and into a guiding channel of the guide rail. The guiding element is an independent component that is fixed, for example, by plugging or screwing onto a bearing element of the scroll bearing. The guiding element is particularly formed as an injection molded part, wherein a parting line of the injection molding tool extends such that when the guiding element is placed on the bearing element of the scroll bearing, the resulting parting burr does not penetrate a guiding or contact surface having the scroll web. By this configuration, side recesses should be avoided when injection molding the bearing element, which are necessary in an integral configuration of the bearing element and the guiding element. Summary of the Invention

[0003] The object of the present invention is to provide a scroll bearing as mentioned at the beginning of this text, which is improved in terms of the configuration of the guiding unit, and to provide an injection molding tool for injection molding such a scroll bearing.

[0004] According to the present invention, this object is solved in the scroll bearing mentioned at the beginning of this text in such a way that the guiding unit has a guiding front section facing the scroll and a guiding main section facing the guide rail; a guiding contact surface of the guiding main section that guides the scroll edge onto the guide rail protrudes relative to a guiding contact surface of the guiding front section that guides the scroll edge out of or to the scroll; and the scroll bearing and the guiding front section and the guiding main section of the guiding unit are integrally formed as a plastic injection molded part in an injection molding tool.

[0005] Furthermore, the object is solved by an injection molding tool for injection molding such a scroll bearing, wherein the injection molding tool has a rotating or inclined sliding member for molding a guiding main section of the guiding unit that has side recesses and a guiding contact surface of the guiding main section that particularly guides the scroll web or the scroll edge.

[0006] Advantageous configurations of the present invention are given in the dependent claims.

[0007] Thus, in the scroll bearing of the present invention, at least two functional or guiding regions of different configurations of the guiding unit can be integrally injection molded with the scroll bearing as a structural unit. These two functional regions configured as a leading front section and a leading main section can be arranged adjacent to each other, but are arranged so spaced apart from each other as desired that they can be manufactured or injection molded by different sliding members or tool parts of the injection molding tool. Since the guiding contact surface of the leading main section for guiding the rolling shutter edge strip onto the guide rail protrudes relative to the guiding contact surface of the leading front section for leading the rolling shutter edge strip out of or onto the scroll, a uniquely defined separating portion is obtained, which is at the same time a transition portion with a high protrusion or a high offset. The functional or guiding region includes a sliding surface on which the rolling shutter edge strip unfolds from its flat and especially folded posture on the scroll and is brought together with the guiding strip mounted on the rolling shutter edge strip into a posture in which the rolling shutter edge strip and the guiding strip can be transferred to an assigned guiding device, for example, transferred to the guiding channel of the guide rail. The guiding contact surface of the leading main section and the guiding contact surface of the leading front section represent such sliding surfaces, where these guiding contact surfaces can be shaped, for example, flatly, curvedly or archedly and can be formed as a continuous surface or as at least two separate surfaces respectively.

[0008] According to a preferred configuration, at least one transition region that is not in contact with the rolling shutter edge strip is formed between the guiding contact surface of the leading front section and the guiding contact surface of the leading main section. Such a non-contact transition region is especially formed on the high protrusion or high offset portion between the guiding contact surface of the leading front section and the guiding contact surface of the leading main section. The injection molding tool can be designed such that a separating seam extends in this transition region, and this separating seam can especially be formed on the guiding unit of the scroll bearing between the sliding members of the injection molding tool and is accompanied by an undesired material accumulation portion in the form of separating burrs. In this transition region, such separating burrs are harmless. On the contrary, the separating burrs formed in the guiding contact surface in the guiding unit of the prior art must be removed by additional reprocessing.

[0009] Therefore, it is particularly preferred that, based on the configuration described above, the guiding contact surface of the leading front section and the guiding contact surface of the leading main section are formed without separating burrs during injection molding.

[0010] Desirably, the leading main section has a shape that rises and bends from the inside out in the transverse direction or the y direction or along the bearing axis of the scroll. Desirably, the free end of the leading main section is formed by a guiding contact surface designed in an arched manner. This design supports injection molding by means of a rotary sliding member or an inclined sliding member of the injection molding tool.

[0011] Preferably, the roller bearing comprises a bearing pin on which a slat having a discharge edge or a curved discharge surface can be mounted, and the rolling blind web slides on the slat when being wound onto and unwound from the roller. The bearing pin is preferably arranged approximately parallel to and spaced apart from the bearing pin of the roller.

[0012] Accordingly, the bearing pin is formed on a carrier plate on which the guide rail is formed. For a flat and horizontally uniform transition, the carrier plate can be adapted to the bottom surface of the guide channel of the guide rail.

[0013] The injection molding tool of the present invention is characterized in that the injection molding tool has a rotary or inclined sliding member for molding the guiding main section with a side recess of the guiding unit and in particular the guiding contact surface for guiding the rolling blind web or the rolling blind edge strip of the guiding main section.

[0014] In a preferred configuration, the injection molding tool additionally has a sliding member, in particular an inclined sliding member or an inclined ejector, for molding the guiding contact surface of the guiding front section. Separating the molding of the guiding front section and the guiding main section into two sliding members can improve the injection molding of the side recesses on the component.

[0015] Accordingly, the rotary sliding member is pivotally supported about a swing axis which is oriented in the longitudinal direction or the x-direction on the roller bearing or in a direction perpendicular to the bearing axis of the roller. The axis or direction description is based on the x-y-z vehicle coordinate system, which also applies to the roller bearing according to the installation state of the roller bearing on the vehicle.

[0016] Furthermore, it can be provided that the additional sliding member or the inclined sliding member is guidingly supported in a longitudinal movement, in particular along the longitudinal direction or the x-direction, for demolding. This longitudinal movement is suitable for avoiding movement conflicts between the additional sliding member and the rotary sliding member.

[0017] Preferably, the rotary sliding member is arranged in the upper part or the upper housing of the injection molding tool. Then, in the lower part or the lower housing of the tool, the position requirements of the cooling channels are not restricted. In addition, the automatic movement of the sliding member can be realized when the injection molding tool is opened or closed and the rotary movement can be carried out in the component direction.

[0018] Other parts of the roller bearing can be integrally molded by the injection molding tool as required by using other sliding members. Description of the Drawings

[0031] A vehicle 1, for example a passenger car, includes a roof 2 with a transparent roof section 3 which is formed, for example, by a glass cover 4 of a sliding roof or a fixedly arranged roof part or roof section. Below the transparent roof section 3, a vehicle roller blind device 5 is provided which has a roller blind web 6 for covering the transparent roof section 3. The roller blind web 6 is made, for example, of fabric, woven material or foil or the like and has a pulling awning frame 7 at its free front edge or pulling end. The pulling awning frame is movably supported at its two side ends on assigned, lateral guide rails 8 which extend in the direction of movement of the pulling awning frame 7 and the roller blind web 6 in the region below the side edge 9 of the transparent roof section 3 in the longitudinal direction of the roof. The vehicle roller blind device 5 has a winding shaft 10 which is arranged, for example, transversely on the roof 2 behind the roof section 3 to be covered and is rotatably supported by means of two end-side winding shaft bearings 11. The two winding shaft bearings 11 are arranged in the region of the rear ends of the two guide rails 8 with respect to the longitudinal direction of the roof.

[0032] The roller blind web 6 is fixed at its rear edge or rear end to the winding shaft 10 and is wound onto the winding shaft 10 which is preloaded by spring force in the winding direction. Each guide rail 8 has a fork guide device 12 (see Figure 4 ), on which a drive fork (not shown) is movably supported. The drive fork is connected on the one hand to an awning slide arranged on the side end of the pulling awning frame 7 (the awning slide is movably supported on the guide rail 8) and on the other hand can be adjusted by a drive motor. By means of two drive cables, the pulling awning frame 7 can be adjusted along the two guide rails 8 to wind the roller blind web 6 onto the winding shaft 10 or unwind it from the winding shaft 10, so that a desired covering position of the roller blind web 6 can be set.

[0033] The rolling blind web 6 has rolling blind side strips 14 at its two side edges 13, and the rolling blind side strips are reinforced at the edge sides by guide strips 15, for example flexible metal strips. The rolling blind side strips 14 are received in the guide channels 16 of the guide rails 8 with the guide strips 15 and are longitudinally movable in the guide channels. The guide channels 16 are upwardly open through longitudinal slots 17 which are delimited by an inner guide flap 18 and an outer guide flap 19, and the inner guide flap and the outer guide flap are opposed to each other in the transverse direction. The rolling blind side strips 14 extend upwardly through the longitudinal slots 17 from the guide strips 15 (which bear against the lower guide surfaces of the two guide flaps 18 and 19) and bear against the guide side walls 20 of the guide rails 8, and the guide side walls are formed on the inner guide flap 18 and laterally inwardly delimit the longitudinal slots 17 in the transverse direction. The rolling blind side strips 14 are turned from their vertical orientation, for example on the guide strips 15, into the horizontal plane of the rolling blind web 6 by the curved or arched guide side walls 20 and the rolling blind web 6 is tensioned based on the same support on the opposed guide rails 8. Thus, the guide strips 15 have such a width and bending strength that the tensioned rolling blind web 6 cannot pull the rolling blind side strips 14 thereof upwardly out of the guide channels 16 through the longitudinal slots 17.

[0034] The reel bearing 11 includes a bearing pin 21 on which the reel 10 is rotatably supported, and the reel bearing further includes a bearing pin 22 on which a strip (not shown) having discharge ridges is mounted, and the rolling blind web 6 slides through the strip when being wound onto or unwound from the reel 10.

[0035] The bearing pin 22 is formed on a carrier plate 23 of the reel bearing 11 which is configured as a plastic injection molding. In addition, a guide unit 24 is molded on the carrier plate 23, and the guide unit conveys the rolling blind side strips 14 in the correct orientation to the guide rails 8 or the guide channels 16 when the rolling blind web 6 is unwound from the reel 10. The guide unit 24 forms part of an interface 25 of the reel bearing 11, and the reel bearing 11 is adapted to and fixed to the guide rails 8 through the interface. The guide unit 24 includes a guide front section 26 which faces the reel 10 and with which the rolling blind web 6 has a first guiding contact when being unwound from the reel 10. In addition, the guide unit 24 includes a guide main section 27 which faces the guide rails 8.

[0036] The leading front section 26 and the leading main section 27 are formed on the upper end portion of the channel wall 28, which stands upright on the carrier plate 23 and is adapted to the shape of the guiding channel 16 of the guide rail 8 at the interface 25 of the reel bearing 11, and the channel wall has a vertical wall surface with a transition portion for a flat and non-offset transition to the associated side wall of the guiding channel 16. The channel wall 28 is rounded or chamfered at its end pointing towards the reel 10, so that a funnel-shaped extending wall surface forms a centering conveying portion 29 for guiding the belt 15. The carrier plate 23 adjoins the bottom surface 30 of the guiding channel 16 of the guide rail 8 with a flat and horizontally uniform transition portion.

[0037] The leading main section 27 of the guiding unit 24 extends from the channel wall 28 with an upward-pointing inclination over a section of the carrier plate 23, wherein the substantially planar upper side 31 and lower side 32 (see Figure 5 and 6 ) of the leading main section 27 extend approximately parallel to each other, or in particular rise with a small curvature outwards in the transverse direction. In addition, at least the upper side 31 and optionally the lower side 32 rise in the pulling-out direction of the rolling blind web 6, thereby bringing the rolling blind edge strip 14 to its height position adapted to the guiding side wall 20 of the guide rail 8. The leading main section 27 is formed with a guiding contact surface 33 at its protruding free end, which arches from its upper side 31 towards its lower side 32 and abuts against the rolling blind edge strip 14, while the guiding belt 15 is tensioned by the rolling blind edge strip 14 towards the lower side 32. The rolling blind edge strip 14 tensioned in the transverse direction of the rolling blind web 6 contacts the guiding contact surface 33 on the upper side up to a height line 34, which represents the highest bulge of the leading main section 27 and from which the rolling blind web 6 or the rolling blind edge strip 14 extends tangentially and openly. The arched guiding contact surface 33 has a shape and positioning adapted to the adjacent, arched guiding side wall 20 of the inner guiding tab 18 of the guide rail 8, so that the rolling blind edge strip 14 can slide horizontally uniformly and without offset from the guiding contact surface 33 to the guiding side wall 20 and also in the opposite direction.

[0038] The guide front section 26 of the guide unit 24 is arranged immediately in front of the guide main section 27 in the extension direction of the roller blind web 6. The guide front section 26 has reduced dimensions relative to the guide main section 27, in particular in the vertical direction or z-direction and in the transverse direction or y-direction, and supports the initial expansion of the roller blind strip 14 from its flat, wound-up position with a fold on the winding shaft 10 and the feeding of the roller blind strip 14 to the guide main section 27. The flat upper side 35 of the guide front section 26 is oriented substantially parallel to the upper side 31 of the guide main section 27, but is lowered in the vertical direction relative to the upper side 31 of the guide main section 27, so that an upper transition region 36 is formed, which has, for example, the shape of a throat or groove with a bevel 37 on the adjacent, protruding guide main section 27 and thus forms a defined transition from the upper side 35 of the guide front section 26 to the upper side 31 of the guide main section 27 and thus forms a height difference.

[0039] Furthermore, the front guide section 26 has a guide contact surface 38 which is arranged in the extension direction of the roller blind web 6 in front of the guide contact surface 33 of the main guide section 27 and comprises a curved edge in a top view, which connects the upper side 35 to the lower side 39 of the front guide section 26. The guide contact surface 38 extends approximately linearly from a front starting point 40 at the edge and extends with a bevel toward the upper side 35 and toward the lower side 39 in the transverse direction outwards and in the longitudinal direction to the transition region 36 and ends in a vertical transition region 41 of an obliquely upright guide bevel 42 on the main guide section 27. The upper side 35 and the bevel 39 of the front guide section 26 are arranged at an increasing distance in the extension direction of the roller blind web 6, so that the front guide section 26 has a small wedge shape and its guide contact surface 38 widens toward the vertical transition region 41.

[0040] Between the underside 39 of the front guide section 26 and the underside 32 of the main guide section 29 protruding relative thereto, a lower transition region 43 is formed which is substantially identical to the upper transition region 36 .

[0041] The roller blind strip 14 of the roller blind web 6 which is guided in sliding contact on the guide front section 26 and the guide main section 29 and in particular on the guide contact surfaces 33 and 38 has no contact with the guide front section 26 and the guide main section 27 in the transition areas 36 , 41 and 43 .

[0042] The injection molding tool for the injection molding of a reel bearing 11 with an integrally injected guide unit 24 from plastic, in particular a thermoplastic such as PP or PA6 or PU, comprises a rotary slide 44 (see Figure 10in the schematic diagram), which is pivotally supported about a pivot axis 45 in the upper housing of the injection molding tool, such that it can be deflected in a transverse plane in the y-direction or in the direction of the bearing axis of the reel 10 on the reel bearing 11 for demolding. The rotary slide 44 forms the guiding main section 27 up to the transition regions 36, 41 and 42. Thereby, in particular, the arched guiding contact surface 33 of the guiding main section 27 is completely inside the cavity of the rotary slide 44 and is thus formed without parting burrs from adjacent tool parts or slides. The upper side 31 and the lower side 32 of the guiding main section 27 are formed as surfaces with such a curvature that the curvature midpoints of the respective radii of curvature coincide with the pivot axis 45 of the rotary slide 44. Thereby, demolding can be achieved by the pivoting movement of the rotary slide 44. In this way, undercuts can be formed on the guiding main section 27 in a simple manner with respect to the upper housing of the injection molding tool. The rotary slide 44 deflects in front of other components of the reel bearing 11, for example in front of the guiding piece 46, during its demolding movement, and the guiding piece projects from the bearing wall 47 towards the leading front section 26 above the carrier plate 23 and is pressed against the outer guiding piece 19 of the guide rail 8.

[0043] The slide 48 of the injection molding tool, for example an inclined slide (see Figure 7 ), or the rotary slide is provided for shaping the leading front section 26 and comprises a respective cavity which forms the guiding contact surface 38 at least without parting burrs. The slide 48 is preferably supported so as to be guided in a longitudinal movement in the longitudinal direction or the x-direction for demolding. The small wedge shape of the leading front section 26 serves to simplify demolding by the longitudinal movement of the slide 48. The slide 48 is also used for forming undercuts between the guiding tab 46 and the carrier plate 23.

[0044] The rotary slide 44 and the slide or inclined slide 48 are adjacent to each other such that parting burrs occurring between the rotary slide 44 and the slide 48 can only be arranged in the respective transition regions 36, 41 and 43. Thereby, such parting burrs do not impair the sliding guidance of the hemming strip 14 and the guiding strip 15. Figure 11 The course of the parting seam or the formed parting burrs assigned to the rotary slide 44 is shown by a dashed line 49.

[0045] Other parts of the reel bearing 11 are integrally molded by the injection molding tool as required by using additional slides.

[0046] Thereby, the injection molding tool enables the integral injection molding of the reel bearing 11 and the guiding unit 24, wherein at least the critical sliding surfaces or guiding contact surfaces of the guiding unit 24 are produced without parting burrs.

[0047] Figures 2 to 4Figures 7 to 11 show two different configurations of the reel bearing 11 with a fixed flange 50 for connecting the reel bearing 11 to the corresponding guide rail 8.
