Description

"Lift and slide roof with lifting lever

  The present invention relates to a lifting and sliding roof for motor vehicles comprising a panel for the choice of closing or releasing at least partially a roof opening, which comprises in the front part and both sides, front guide members which are movably guided in guide rails

  connected to a fixed part of the roof, laterally

  port at the roof opening, and the panel being able to be placed in an inclined position from its closed position, by raising its rear edge and being able to be moved backwards into an open position,

  above the fixed part of the roof.

  The rising and sliding roofs of this type which

  are also called roof-fins, are particularly suitable

  particularly well for motor vehicles in the-

  the available height is limited, as is above all the case for relatively small vehicles with a low coefficient cw (coefficient of penetration into the air) for reasons of energy saving. problems with traditional sliding roofs or sliding roofs with a panel that can be slid back under the rigid part of the roof, these problems regarding the importance of the opening that can be

  achieve andjoug the stability of the guidance of the panel.

  The object of the present invention is to create a lifting and sliding roof of low constructive height, which allows relatively large opening angles and whose panel is at the same time guided in such a way that

particularly safe.

  To this end, the invention relates to a sliding and sliding roof of the above type, characterized in that the panel is pivotally supported on

  front guide, in that a lever is provided for

  vage which is pivotally supported on the one hand on a guide member, which is also adjustably guided along the guide rail, and on the other hand is articulately connected by its rear end to the panel, and the lifting lever or a transport carriage sliding along the guide rail carries at least one slide axis which is engaged with a slide guide member (slit slot) of

  the transport element or the lifting lever for

  the panel to tilt and engage to drive the panel in the direction

guide rails.

  The lifting and sliding roof according to the invention is made particularly robust using a relatively small number of components The tilting bearings according to the invention for the panel and the lifting lever, result in combination with the mounting of the slides by which the lever of releage and

  transport trolley cooperate in a

  pact and stable, and small footprint in the direc-

vertically.

  Other features of the inention result

  of the description and claims

  double slide according to the invention requires the le'ier lift to follow with great precision the adjustment movements of the transport member This

  effectively avoids any movement of shaking and

  of the sliding panel, for example, which could occur as a result of the forces of wind acting on the panel. This disadvantage is further reduced by reciprocal elastic prestressing between

  transport and lifting lever and / or

  be the panel and the lift lever.

  FIG. 13 is a partial longitudinal section of a lifting and sliding roof corresponding to another

variant embodiment.

  As shown, at the front part of the roof 1 of a motor vehicle A, there is provided a roof opening 2 The roof opening 2 is surrounded by a joint 3 whose section corresponds essentially to a shape of L. below the roof 1 is a roof frame 4 which limits upwardly the passenger compartment of the vehicle A The roof frame 4 is at the level of the roof opening 2, at a distance from the roof 1 and surrounds a frame opening 5 corresponding to the opening of

roof 2.

  The rectilinear guide rails 6 are mounted on the upper side of the roof frame 4, on both sides of the roof opening 2. The guide rails 6 are provided

  in the longitudinal direction of the vehicle,

  parallel to the roof opening 2 A transport carriage 7 as well as front and rear adjustable guide members 8, 9 slide forwardly or rearwardly along the guide rails 6 The transport carriage 7 comprises a member 11 which is connected to a drive means, for example an electric motor or

  a crank, via a drive mechanism

  10 for example in the form of a threaded cable

  non-compressible The organ 1 l carries two pieces of sliding

  12, which engage with the guide rail 6 For the sliding parts 12 and the guide members 8, 9, it may be

  preferably slip skids of synthetic material

  tick or the like, having in view an essential shape

  elliptical, and which take in the guide rail 6 essentially channel-shaped and

  sliding along the guide rail.

  To close or open the roof opening 2, a rigid panel 13 is provided, for example made of glass, synthetic material, a sheet or the like, that is to say a transparent, translucent or opaque material. In this case, in particular, the underside of the panel is pressed against the upper face of a lower part 3 of the seal 3. The panel 13 is supported. by two fixing means 14a (these means are only shown in Figure II) on two opposing panel supports 14 Each of the two panel supports 14 is hinged at its front end on a guide member 8, before, respectively , and can

  turn around a transverse axis formed by an articu-

21.

  A lifting lever 15 is provided on both sides of the roof opening 2 Each of the lifting levers is pivotally supported in its middle part on a corresponding rear guide member 9 while the rear end of the lifting lever The lift is connected to the corresponding panel support 14 via a hinge 18 The transport carriage 7 and the lift lever 15 are engaged via a cam or slide assembly 16, 17 in the zone

  median of the lift lever In the embodiment of

  As shown, the slide assembly comprises the front and rear slide shafts 16a, 16b of the transport carriage 7 and the slide pads 17a and 17b front and rear of the lift lever 15. conversely the slide pins can also be provided on the lift lever and the slits on the transport carriage The slit slit 17 a forward, which is substantially in front of the tilt axis of the lifting lever 15 formed by the guide member 9, is rectilinear while the rear slit 17b, provided behind the axis of tilting of the lifting lever 15 has a rectilinear front segment and parallel to the slit slit 17a as well as a segment curved downward, following the previous The slide shafts 16a and 16b are essentially at the same height In the closed position of the panel (Figure 2) the front slit 17a and the segment recti line of the rear slit slot 17b are also substantially at the same height In the closed position of the panel, the slide pins 16a, 16b (as is apparent from Figure 2) are substantially symmetrical relative

  to the guide member 9, rear forming the rotational axis

  The slide slot 17a and the straight segment of the slit slot 17b are in the vicinity of the upper edge of the lift lever 15 while the curved segment of the slit slot 17b reaches until neighborhood of the lower edge of the

lifting lever 15.

  When starting from the position shown in Figure 3 in which the panel 13 is above the roof opening 2 and the rear edge of the panel is

  above the fixed part of the roof to provide air

  the transport carriage 7 is slid forward through the drive member 10, the slide pins 16a, 16b slide in the slide carriages 17a, 17b forwards. As long as during this movement, the slide axis 16b traverses the recurved rear segment of the slit slot 17b, the lift lever 15 tilts about the axis of rotation

  formed by the guide member 9, in the direction of the

  1 of a watch according to FIG. 3 This results in a tilting movement of the panel support 14 around the hinge 21, so that the rear edge of the panel goes down. This closes the roof opening 2. described movement, the front slide pin 16 has a push against the upper edge of the slit slot before 17a while the rear slide axis 16B pushes

  on the lower edge of the rear slit slot 17 b.

  The transport carriage 7 then continues to move forwards, so that the slide axis 16b passes into the rectilinear segment before the slit slot.

  17 b This results in the locking of the panel 13 in position

  In the forward movement, the slide axis 16a, 16b in the slit slots 17a, 17b is prevented from continuing its forward movement by a corresponding stop or simply by that the front edge of the panel rests against the

  protruding 3b from the seal 3 at the front edge of the

roof opening 2.

  By against if from the position shown in Figure 2, the transport carriage 7 is slid

  backwards through the training organ.

  10, the slide pins 16a, 16b move rearwardly in the slit slots 17a, 17b. This first results in the loosening of the panel lock. Then, the lift lever 15 switches around. its axis of rotation formed by the guide member 9 in the opposite direction of that of the clockwise according to Figure 2 It follows that the panel support 14 tilts upwardly about the axis of the 21 and the rear edge of the panel 13 is raised as shown in Figure 3 Because the distance between the slide assembly and the hinge 18 connecting the lifting lever 15 and the panel support 14 is greater at the distance between the slide assembly and the guide member 9 forming the axis of rotation of the lifting lever 15, it is obtained that the hinge 18 is raised relatively large although the vertical distance between the position the position the highest and the lowest of the axis d The latter feature has the advantage that the raising device of the lifting and sliding roof occupies only a relatively small space requirement in height and does not

  lose that low volume under the roof of the cockpit.

  The front end of the lifting lever 15 extends beyond the axis of rotation (guide member 9) of the lifting lever 15 towards the front and carries a guide element 19 when the lifting lever 15 leaves the position of FIG. 2 to switch to the position of Figure 3, the guide member 19 passes through a cutout 20 of the upper flange of the guide rail 6 to enter the guide rail 6 and can be slid along the guide rail The guide member 19 thus cooperates with the guide member 9 and the guide rail 6 to maintain the lifting lever 15 in the tilted position according to Figures 3 and 4 This ensures a support for the panel 13 On the other hand if the The panel 13 is passed from the raised position (FIG. 3) to the closed position (FIG. 2), the guide element 19 leaves the cutout 20 of the guide rail 6.

  transport 7 from the position shown in FIG.

  re 2 is moved rearwardly, the guide member 19 abuts an abutment surface 20a at the cutout 20, so that the panel 13 can not slide rearward This ensures that for a displacement of the transport carriage 7 to the rear, the panel 13 is first raised before the panel 13 is driven

  rearward by the transport trolley 7.

  As long as the panel 13 is aligned with the roof opening 2, the hinge 21 which supports the panel support 14 is at the front guide member 8 in front of the front edge of the roof opening 2 If after that, the panel 13 is moved from its closed position (FIG. 2) to the raised position

  (Figure 3), the front edge of the panel 13 is recovering progressively

  Thus, the front edge of the panel is no longer

  under the plane of support of the panel formed by the lower edge

  In this way, the seal 3 is prevented from being subjected to troublesome stresses during the lifting movement of the panel 13. Furthermore, by moving the rotation axis of the support panel 14, improves the stability of the entire

  mounting due to the relatively long lever arms.

  When the transport trolley 7 from the

  position of Figure 3 continues to slide towards the

  by driving the panel 13 by the support of the slide pins 16a, 16b against the rear ends of the slits 17a, 17b, the guide member 9 and the guide member 19 which both move in the guide rail 6, are maintained in the raised position on the lifting lever 15 The panel 13 can thus be placed in the open position according to the figure

  4 and overall there is a special provision

  The fact that the hinge 18 between the panel support 14 and the lift lever 15 is arranged to be behind the rear edge of the roof opening 2 in the open position of the panel

participate in this purpose.

  The inner end of the front slide shaft

  16 has penetrated inwards (as shown in the figures

  5 and 6) from the body 11 of the transport carriage 7 A coil spring 22 connects the slide axis 16a to a retaining plate 31 which protrudes from the inner side of the lift lever 15 in its area.

  In the embodiment shown, the resistor

  22 draws the transport carriage 7 backwards relative to the lifting lever 15 The spring 22 thus pushes the slide pins 16a, 16b against the

  rear ends of the slits 17 a, 17 b when

  that the panel 13 is raised The spring 22 in this way participates in the stabilization of the panel 13 in the raised position This spring absorbs the game which may result in manufacturing tolerances, particularly in terms of assembly

  16, 17 In a variant, the front end of the housing

  fate 22 can also be provided on the slide axis

  rear 16b or on the member 11 of the transport carriage 7.

  A training member 23 is fixed in a manner

  vible on the inner end of the slide axis 16 a.

  Sliding guide means 25 extend along guide rail 6 Guide means 25 is held by screws 24 which at the same time secure attachment of guide rail 6 to roof frame 4 Sliding plate 27 relies through a means of

  fixing 26 on the sliding guide means 25.

  The plate 27 can optionally move forwards or backwards to close the frame opening 5 or to disengage it. When the panel 13 is moved backwards by the transport carriage 7, the body drive 23 leans against the fastening means 26 and drives the sliding plate 27; at the same time as the release of the roof opening 2, it also frees

the frame opening 5.

  One end of a leaf spring 28 is fixed by a rivet 29 or similar member on the panel support 14 while the other free end of the spring is resiliently applied against the upper face of the fixing plate 31 If against the panel 13 is in the raised position, the spring 28 creates a tension between the panel 13 and the lifting lever 15 This also allows

to absorb a possible Game.

  FIG. 9 shows an embodiment variant

  in which the slit 17 is not a

smooth continues but a groove.

  In the embodiment of FIGS. 10, 11, 12, the springs 22, 28 are omitted. Furthermore, in this case, there is no sliding plate. For the rest, the mounting and the operation of the lifting and sliding roof.

  correspond to the roof of Figures 2 to 8.

  Figure 13 shows another variant of

  in which when the panel 13 is in the closed position, the hinge 21 which supports the panel support 14 is provided on the guide member 8, before, directly below the front edge of the roof opening This makes it possible to preserve the gap between the front edge of the panel 13 and the highest part 3b of the joint 3 during raising and lowering of the panel 13 which is minimum.

  avoid the penetration of rainwater during the

  vehicle, the panel being in the raised position.

  Wind noise is also maintained at one level

  particularly weak The panel support 14 is rela-

  quickly and the lift lever 15 is connected by

  through articulation 18 directly to the

water 13.

  The slide assembly comprises only a slide axis 16 and a single slide slot 17.

  has no member corresponding to the guide member 19.

  In this case to maintain the panel 13 in the raised position, there is provided a spring 22 which connects the slide axis 16 to a point of the lifting lever 15 located

  behind the slide axis 16 and maintains the axis of cou-

  smooth 16 in engagement with the rear end of the slot

slide 17.
