Abstract
Abstract For limiting the rotational or angular movement of a drive spindle about its axis, such as in a rotary drive for the sliding roof of a motor vehicle, abutments or stops are associated with the driving spindle and with a slide movably displaceable relative to and transversely of the drive spindle, for effecting the limiting action. The drive spindle extends through a housing and the slide is movably positioned within the housing. An eccentric disk is fixed to the drive spindle and a ring is rotatably mounted on the disk and has teeth on its circumferential periphery. An arcuate portion of the teeth on the ring intermesh with teeth formed in the housing. Due to the eccentricity of the disk and ring, during each 360* turn of the drive spindle there is a displacement of the ring relative to the housing. Abutment surfaces are provided on the ring extending toward the slide. The slide is displaceable between two positions and has a pair of abutments so that in each of its positions one of its abutments is located in the path of the abutment surfaces on the ring. When the abutment surface on the ring contacts the abutment on the slide further angular movement of the drive spindle in a particular direction is prevented.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
294 words
A device including a drive spindle and the device arranged for limiting the revolution of said drive spindle such as for use in the rotary drive for the sliding roof of a motor vehicle, a disk rigidly connected to and extending transversely of said drive spindle, the axis of said disk being disposed eccentrically of the axis of said drive spindle, a ring rotatably mounted on the circumferential periphery of said disk and having gear teeth formed in its outer circumferential peripheral surface, a stationary housing laterally enclosing said disk and ring and having a cylindrically shaped surface concentric with the axis of said shaft and disposed about the circumferential periphery of said ring, said housing having gear teeth formed in said cylindrically shaped surface, the radius of the dedendum circle of said teeth on said housing being larger than the radius of the addendum circle of said teeth on said ring by an amount substantially equal to the eccentricity of said disk relative to the axis of said drive spindle, abutment means on said housing and said ring for limiting the angular movement of said drive spindle, wherein the improvement comprises a slide mounted in said housing and extending transversely of the axis of said drive spindle, said abutment means comprises a pair of spaced abutment members secured to and extending outwardly from said slide toward said ring, said slide being movably positionable within said housing transversely of the axis of said drive spindle for selectively alternatively locating one of said abutment members in the path of said abutment means on said ring with the other said abutment member disposed out of the path of said abutment means on said ring for providing a stop for the angular movement of said drive spindle.
Claim 2
Independent Claim
294 words
A device including a drive spindle and the device arranged for limiting the revolution of said drive spindle such as for use in the rotary drive for the sliding roof of a motor vehicle, a disk rigidly connected to and extending transversely of said drive spindle, the axis of said disk being disposed eccentrically of the axis of said drive spindle, a ring rotatably mounted on the circumferential periphery of said disk and having gear teeth formed in its outer circumferential peripheral surface, a stationary housing laterally enclosing said disk and ring and having a cylindrically shaped surface concentric with the axis of said shaft and disposed about the circumferential periphery of said ring, said housing having gear teeth formed in said cylindrically shaped surface, the radius of the dedendum circle of said teeth on said housing being larger than the radius of the addendum circle of said teeth on said ring by an amount substantially equal to the eccentricity of said disk relative to the axis of said drive spindle, abutment means on said housing and said ring for limiting the angular movement of said drive spindle, wherein the improvement comprises a slide mounted in said housing and extending transversely of the axis of said drive spindle, said abutment means comprises a pair of spaced abutment members secured to and extending outwardly from said slide toward said ring, said slide being movably positionable within said housing transversely of the axis of said drive spindle for selectively alternatively locating one of said abutment members in the path of said abutment means on said ring with the other said abutment member disposed out of the path of said abutment means on said ring for providing a stop for the angular movement of said drive spindle.
Claim 3
Dependent Claim
60 words
A device, as set forth in claim 1, wherein said abutment members on said slide being located on opposite sides of the axis of said drive spindle relative to one another and said slide and abutment members being arranged so that one of said abutment members is always in the path of movement of said abutment means on said ring.
Claim 4
Dependent Claim
36 words
A device, as set forth in claim 2, wherein said slide has a slot therethrough elongated in the direction of movement of said slide relative to said drive spindle,and said drive spindle extends through said slot.
Claim 5
Dependent Claim
33 words
A device, as set forth in claim 1, wherein said abutment means on said ring comprises a pair of angularly spaced abutment surfaces secured to and extending from said ring toward said slide.
Claim 6
Dependent Claim
71 words
A device, as set forth in claim 4, wherein said abutment means comprises a rib secured to and extending outwardly from the face of said ring directed toward said sleeve, said rib having an arcuate configuration being spaced inwardly of the circumferential periphery of said ring and being disposed concentrically of the axis of said ring, and said pair of abutment surFaces each located on an opposite end of said rib.
Claim 7
Dependent Claim
63 words
A device, as set forth in claim 1, wherein said slide being positionable between a first position and a second position, and spring means associated with said housing for holding said slide in the one of the first and second positions into which it is located and for biasing said slide from any intermediate position into one of the first and second positions.
Claim 8
Dependent Claim
105 words
A device, as set forth in claim 6, wherein said housing having a recess therein extending along one side of the path of movement of said slide, said slide having a V-shaped cam projecting outwardly from the side thereof adjacent said recess into the recess in said housing, and said spring means comprising a stirrup spring positioned within said recess and having a V-shaped projection extending into the path of said cam for engaging said cam in each of the first and second positions of said slide for holding said slide in the one of the first and second positions in which it is located.
Claim 9
Dependent Claim
69 words
A device, as set forth in claim 1, wherein said slide being positionable between a first position and a second position, said slide having a notch formed in one of the sides thereof extending in the direction of movement of said slide relative to said drive spindle, and means articulated to said housing and positioned within said notch for moving said slide between the first and second positions thereof.
Claim 10
Dependent Claim
66 words
A device, as set forth in claim 8, wherein said means for moving said slide comprises a lever pivoted to said housing and extending at one end into said notch in said slide and having its other end projecting outwardly from said housing so that said outwardly extending end can be manipulated for actuating said lever and displacing said slide between its first and second positions.
Claim 11
Dependent Claim
43 words
A device, as set forth in claim 9, wherein a hat-shaped actuating button articulated to the outer end of said lever and disposed in surface contact with the periphery of said housing in each of the first and second positions of said slide.
