Description

Technical Field

[0001] The invention relates to a sunshade screen assembly. Background Art

[0002] A roof assembly with such a drive and guide system is known from JP H10129268A2. One drive cable operates the front and rear mechanisms, each requiring a different travel length for operation. The drive cable is operated via a pin / bend associated with a locking lever, which locks or unlocks the front mechanism while still moving the rear mechanism. Summary of the invention

[0003] An object of the present invention is to provide a sunscreen assembly having a coupling member which is easier to couple and detach.

[0004] For this and other purposes, the sunscreen assembly according to the invention comprises the feature that the connection guide is shaped to cause movement of the coupling member when the first and second drive members are moved to open or close the first and second sunscreens.

[0005] Since the connection guide itself is shaped to move the coupling member, the structure can be relatively simple without various movable parts.

[0006] Preferably, the coupling member is rotatable about an axis substantially parallel to the first slider track, and the connection guide is shaped to cause rotation of the coupling member.

[0007] Such rotation is relatively easy to accomplish in a reliable manner.

[0008] In one embodiment, the coupling member is fixed to an elongate first drive member, the elongate first drive member being able to twist about its longitudinal axis.

[0009] Such a twisting can be achieved, for example, by means of a well-known push-pull cable as an elongated drive member, and in this case the cable itself ensures a return force which makes the control more reliable in both directions.

[0010] The connection guide may include a longitudinal guide conduit to guide the elongated first drive member, the guide conduit opening through a control slit to allow the connecting member to extend between the first drive member and the mating member, the slit being curvilinear along the length of the guide conduit to cause rotation of the connecting member.

[0011] This makes it easy to control the rotation of the coupling member without the need for any moving elements.

[0012] The coupling member and the mating member may include mating protrusions / grooves that lock the coupling member and the mating member in the longitudinal direction.

[0013] Such protrusions and grooves can be easily engaged with and separated from each other.

[0014] In one embodiment, the connection guide is injection molded and is made of at least two parts which together define the guide duct for the coupling member and the control slit.

[0015] If the connecting guide is produced from at least two injection-molded parts, there is a great deal of freedom in the design of the control slot.

[0016] The parts of the connecting guide may be provided with positioning and fixing means to assemble and fix the two parts in the correct position.

[0017] Preferably, the connecting guide is provided with an end portion which is fitted into end portions of the first guide and the second guide.

[0018] This attachment method can ensure a smooth transition of the drive member on the one hand and a correct attachment of the connecting guide relative to the first and second guides on the other hand.

[0019] In one embodiment, the sunscreen is arranged to move in opposite directions, and thus the first drive member and the second drive member are arranged to move in opposite directions at equal speeds.

[0020] In this embodiment, the first drive member and the second drive member may be separate elements arranged parallel to each other and moving in opposite directions.

[0021] When the sunscreen is arranged to move in the same direction, and thus the first and second drive members are arranged to move in the same direction at equal speed, the first and second drive members are preferably arranged in series and may form two parts of a single element.

[0022] In another aspect of the present invention, a drive member guide is provided at the second end of the first guide member, and when the connecting member must be separated from the paired member, the connecting member of the first drive member reaches the drive member guide, and the drive member guide is formed to cause the movement of the connecting member when the first and second drive members move further to open or close the second sunshade screen member.

[0023] This enables various arrangements of the sunscreen. The sunscreen is preferably a roll-up sunscreen, but may also comprise a sliding sunscreen panel or other moving sunscreen.

[0024] The invention also encompasses a roof assembly for a vehicle having a roof opening in its fixed roof, the roof assembly comprising at least one closing member for closing and at least partially opening the roof opening and further comprising a sunscreen assembly as described above.

[0037] The present invention will now be described with reference to the drawings, wherein like reference numerals are used throughout the several views to identify the same or similar elements.

[0038] like Figure 1 The sunscreen assembly shown in the figure is intended for use in a roof assembly disposed in one or more roof openings of a vehicle roof. The roof assembly may include a movable panel and a fixed panel. The movable panel is also referred to as a closing member because the movable panel can be moved over the first roof opening so as to be able to open and close the first roof opening.

[0039] The movable panel can be moved to a closed position, which is a position in which the movable panel is arranged above / inside the first roof opening and closes the first roof opening, and thus the movable panel is generally arranged in the plane of the roof. Further, the movable panel can be moved, for example, to an inclined position, which is a position in which the rear end of the movable panel is raised compared to the closed position, while the front end of the movable panel is still substantially in the closed position. Further, the movable panel can be moved to an open position, which is a position in which the movable panel slides open (mostly in the rearward direction) and the first roof opening is partially or completely exposed. Other movements are conceivable.

[0040] It should be noted that the vehicle for which the roof assembly is intended is a passenger car. However, the present invention is not limited to passenger cars. Any other type of vehicle that can be provided with a roof assembly and a sunscreen assembly is also contemplated, such as a truck, mobile home or caravan.

[0041] The roof assembly comprises a second roof opening, which can be closed by a fixed panel so that light can enter the vehicle interior space through the fixed panel, assuming that the fixed panel is a glass panel or a similar (semi-) transparent panel made of, for example, a plastic material or any other suitable material. It should be noted that the second roof opening can be integrated with the first roof opening. The roof assembly as described above can, for example, be similar to the roof assembly disclosed in US2019 / 0176603A1, the content of which is incorporated herein by reference.

[0042] Figure 1 and 2 A first embodiment of a sunscreen assembly is shown, which includes a first or front roller blind sunscreen 1 to block light passing through a first roof opening, and a second roller blind sunscreen 2 to block light passing through a second roof opening. Typically, the frame of the roof assembly forms a first passage opening below the first roof opening and a second passage opening below the second roof opening, the first and second passage openings being selectively opened and closed by the first and second sunscreens 1, 2.

[0043] The sun screens 1, 2 are typically made of a cloth material and have end edges attached to winding reels 3, 4, respectively, opposite end edges attached to operating beams 5, 6, respectively, and opposite side edges 7, 7' and 8, 8'. In this embodiment, the winding reels 3, 4 are arranged back to back so that the rolling sun screens move in opposite directions when they perform a winding (opening) or unwinding (closing) movement. Other arrangements are conceivable.

[0044] Figure 1 Further shown is a drive assembly for a sunscreen having a first guide 9, 9', a second guide 10, 10', a first drive cable 11 and a second drive cable 12, which in this embodiment form elongated first and second drive members 11, 12. The first and second guides 9, 9' and 10, 10' are arranged to guide the respective side edges 7, 7' and 8, 8' on the opposite side edges of the sunscreen 1, 2, respectively, in a well-known manner, for example as shown in Figure 8. The guides 9, 9', 10, 10' are typically coupled to a frame or other fixed component (not shown) below the opposite side edges of one or more roof openings. The first and second drive cables 11, 12 are arranged to move the opposite ends of the operating beams 5, 6, respectively, and are driven by a drive motor 13. The first guides 9, 9' will typically also be used to guide the operating mechanism for the movable panel. This is not shown and does not form part of the present invention.

[0045] As described above, the drive cables 11, 12 connect the drive motor 13 to the operating beams 5, 6. One end of the drive cable 11 may be connected to the operating beam 5 of the sunscreen 1 in the front guide 9, and the other end - which moves in the opposite direction on the other side of the sunscreen 1, 2 - is connected to the operating beam 6 of the sunscreen 2 in the second guide 10'. One end of the drive cable 12 is connected to the operating beam 6 of the sunscreen 2 in the rear guide 10, and the opposite end - which moves in the opposite direction on the other side of the sunscreen 1, 2 - may be connected to the operating beam 5 of the front sunscreen 1 in the front guide 9'. The drive cables 11, 12 are typically push-pull cables well known in the art and are therefore not further explained here.

[0046] Figure 2 It is shown that the operating beam 5 of the sunshade screen 1 can travel a length l1, and the operating beam 6 has a maximum travel length l2, which is longer than the length l1 by a length l3. This means that if the two sunshades 1 and 2 are moved from the fully open (wound) position to the fully closed (unrolled) position, the two sunshades 1, 2 move simultaneously through the length l1, after which the sunshade screen 1 should be stopped and the sunshade screen 2 is moved further through the length l3. The present invention provides a solution for interrupting the drive of one of the sunshades in a simple and effective way.

[0047] Figure 3a-3c One side edge 7, 8 of the sunscreen 1, 2 and their guide and drive means are shown. The same components are generally present at the other side edge, but in a mirror image, only the cables 11, 12 are switched as described above. Figure 3a The two sun screens 1, 2 are shown in their closed (deployed) position (part of the sun screens 1, 2 is cut away). Figure 3b In the embodiment of the present invention, the front sunshade 1 has reached its fully opened (wound) position, while the rear sunshade 2 is still a length l3 from its opened position. The cable 11 is then disconnected from the operating beam 5 of the front sunshade 1, while the rear sunshade 2 continues to be connected to the cable 12 and is thus driven further to the open position. Figure 3c In the position, both sunshades 1 and 2 are opened.

[0048] 4a, 4b show a fixed connection between the cable 12 and the operating beam 6 of the sunscreen 2. As shown, the connection member 14 is clamped to the cable 12 so that it is locked against sliding relative to the cable 12, but can be rotated around the longitudinal axis of the cable 12 if necessary. The connection member 14 is fitted into a slide 16 of the operating beam 6 so that no movement between them is possible. Figure 3a-3c It is shown that the slider 16 of the operating beam 6 is guided by the slider track 10 a of the second guide 10 between the first and second track ends.

[0049] Figure 5a , 5b The detachable connection between the cable 11 and the operating beam 5 of the sunscreen 1 is shown. At the end of the operating beam 5 there is a slide 15 into which a mating member 17 can be fixedly fitted. The slide 15 is guided by the slide rail 9a between the first and second rail ends (see Figure 3a-3c ). The coupling member 18 is fixed to the cable 11, for example by moulding the coupling member 18 onto the end portion of the cable 11, but it is also possible to connect the coupling member 18 to the cable 11 and make it rotatable around the longitudinal axis of the cable 11. The coupling member 18 is provided with a lateral protrusion 19 on its end remote from the cable 11. Next to the protrusion 19 is a lateral groove 20 and then a lateral protrusion 21. The counterpart member 17 comprises a nose 22 which fits in the groove 20 between the protrusion 19 and the protrusion 21. If the coupling member 18 is in the guide 9, it is prevented from rotating around the axis of the cable 11 and in this position the nose 22 is locked in the groove 20 between the protrusion 19 and the protrusion 21 on the coupling member 18.

[0050] 6a and 6b show a drive member guide or connection guide 23 between the first or front guide 9 and the second or rear guide 10. In this embodiment, it comprises two parts 23a, 23b (further explained later) assembled together, which together define a first guide duct 24 for guiding the end of the first cable 11 coming out of the first guide 9, and a second guide duct 25 for guiding the second cable 12 from the first guide 9 to the second guide 10. It may be supported by a support bracket 26 for the winding reels 3, 4.

[0051] FIG. 6 b partially shows that the first guide duct 24 is open on the upper side via a control slit 27 .

[0052] Figure 7a-7c The curve of this control slit is shown by the dashed line 27. Through this control slit 27 the coupling member 18 exits to connect the cable 11 (not shown) and the counterpart member 17 of the operating beam 5 of the first roller blind 1. The control slit 27 comprises a lateral step 27a at the location where the coupling member 18 must be coupled / decoupled from the counterpart member 17. This lateral step 27a moves the upper part of the coupling member 18 in the lateral direction and, since the coupling member 18 is attached to the cable 11, the coupling member 18 will rotate about the longitudinal axis of the cable 11. Due to this rotation, the coupling member 18 will move away from / towards the counterpart member 17 so that the nose 22 of the counterpart member 17 will move away from / into the groove 20 of the coupling member and thereby effectively decouple / decouple the cable 11 from the operating beam 5 of the sunscreen 1.

[0053] Figure 7a It is shown that the nose 22 engages with the groove 20 between the protrusion 19 and the projection 21. Figure 7b In the embodiment, due to the step 27a in the control slot 27, the coupling member 18 rotates away from the counterpart member 17, and the nose 22 thus moves away from the groove 20 to a certain extent so that the protrusion 21 can pass through the nose 22, thereby enabling the cable 11 to continue to move without taking the operating beam 5 with it. At the same time, the cable 12 will move the operating beam 6 of the second sunscreen 2 to the fully open position.

[0054] Figure 8a-8c The rotation of the coupling member 18 is shown in more detail, and the position of the coupling member 18 is shown in more detail. Figure 7a-7c Corresponding. Figure 8a In the embodiment, the coupling member 18 is located in the first guide 9, in which the coupling member 18 is locked against rotation. Figure 8b , the coupling member 18 has reached the connection guide 23, and one wall of the control slit 27 has allowed rotation. Figure 8c , the opposing walls of the control slot 27 push the coupling member 18 to rotate to allow the nose 22 of the mating member 17 to leave the groove 20 and allow the protrusion 21 to pass and thus separate from the coupling member 18.

[0055] Fig. 9 It is shown how one end of a first guide duct 24 and the opposite end of a second guide duct 25 are inserted into the first and second guides 9, 10. The end portion 28' of the cable channel 28 in the first guide 9 and the end portion 29' of the cable channel 29 in the second guide 10 are widened to receive the ends of the guide ducts 24, 25 and provide a substantially smooth guidance of the cables 11, 12 (not shown here) at the transition between the guides 9, 23, 10. For the sake of clarity, it should be noted that the guides 9, 10 are substantially aligned but have a slight curvature to adapt to the curvature of the fixed roof of the vehicle. Such a curvature can also be present in the connecting guide 23.

[0056] Figure 10 clearly shows the parts 23a, 23b of the connecting guide 23 and how they are connected. Figures 10a, 10b show the connecting guide 23 in an assembled state, and Figures 10c and 10d are exploded views in which parts 23a and 23b are separated. In this embodiment, parts 23a, 23b are made of plastic by injection molding. They each have a platform 30, 31 so that the platform 31 of part 23b is assembled to the platform 30 of part 23a. Platform 30 includes two keyhole-shaped openings 32, and two equally spaced mushroom-shaped protrusions 33 are formed on the lower side of platform 31 so that the head of protrusion 33 can be inserted through the larger part of opening 32, and then parts 23a and 23b can be moved toward each other, so that the second guide catheter 25 is closed and then the rod of protrusion 33 is in the smaller part of opening 32, and the head of protrusion 33 locks parts 23a and 23b to prevent vertical movement. A small pin 34 may be provided on part 23a to fit securely into an opening (not shown) in part 23b to further secure parts 23a and 23b together. Parts 23a and 23b may have additional means to further secure the connecting guide 23 to the first and second guides 9, 10, such as resilient protrusions that fit into holes in the guides.

[0057] Fig.11 and 12 Two further embodiments of the sunscreen assembly are shown in a very schematic manner. An important difference is that in these embodiments the sunscreens move in the same direction instead of in opposite directions. This means that on one side edge of the sunscreen 1, 2, the two operating beams are driven by the same cable, on the edge shown in the figure, by the cable 11.

[0058] exist Fig.11 In the embodiment of the present invention, the front sunshade screen 1 has a shorter unfolded length, such as in Figure 1-1 0. This means that the end of the cable 11 is permanently connected to the operating beam 6 of the sunshade 2. The coupling member 18 for the sunshade 1 is now attached at a distance from the end of the cable 11 so as to couple and detach with the mating member 17 on the operating beam 5 of the sunshade 1. Now, when the sunshade 1 is completely closed (deployed), detachment occurs and the sunshade 2 should be further deployed. The control of the coupling member 18 can be carried out in the same way as in the previous embodiment, that is, by means of a connecting guide with a control slit. However, the connecting guide now only requires one guide duct only for the cable 11, which extends through the connecting guide from the first guide 9 to the second guide 10. The slide for the operating beam 5 should be automatically braked to remain in the appropriate position when the cable 11 is separated, or some other brake or lock should be provided to keep the sunshade 1 in the appropriate position.

[0059] Fig.12 The embodiment of is different in that the longer second sunscreen 2 is now arranged as the front sunscreen. Therefore, the fixed coupling member 14 is now attached at a distance from the end of the cable 11 and the coupling member 18 is attached to the end of the cable 11. The control of the coupling member 18 must be carried out at the rear end of the first guide 9, where the drive member guide 39 with the control slit is attached to the first guide 9. Therefore, the drive member guide 39 is positioned at the end of the first guide 9 like the connecting guide 23. In this embodiment, the connecting guide may not be necessary and the guides 9 and 10 can be integrated into one guide.

[0060] From the foregoing it is evident that the invention provides a simple and effective assembly for operating two different sunscreen members by a single electric motor.Thanks to the simple and reliable coupling member, one sunscreen member can be further operated while the other remains in an end position.
