Abstract
Abstract An improved arrangement for accommodating movement of a manual crank member for a sliding and tilting roof is provided. The crank member is drivingly connected to a shaft, which shaft is connected by a lost motion connection with a driving plate, which driving plate in turn includes a stop member engageable with a stop member on a driving gear connected for movement with the vehicle roof member. The lost motion connection between the shaft and the plate member corresponds to the angular rotation equivalent to the sum of the circumferential length of the stop members at the plate and the driven gear, so that the crank member can be freely returned to a single predetermined rotative position where it can be moved into a roof recess or the like to be concealed, irrespective of the position of the roof member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
235 words
Movable vehicle panel member apparatus including a vehicle panel member and driving means for moving said panel member with respect to adjacent vehicle structure, said driving means including: a rotatable driving member which is drivingly connected to move said panel member in response to rotational movements of said driving member, said driving member having a first stop member, a shaft, a crank member drivingly connected to said shaft for applying rotational movement to said shaft, and a driving plate carried by said shaft, said driving plate having a second stop member engageable with said first stop member to rotate said driving member along with said driving plate, said first and second stop members occupying a small circumferential length of said driving member and driving plate so that said driving plate can be freely rotated from a first position with the second stop member engaging one circumferential side of said first stop member to a second position with the second stop member engaging an oppositely facing circumferential side of said first stop member, said shaft and said driving plate being connected by lost motion connecting means permitting free relative rotational movement corresponding to the angular range determined by the circumferential lengths of the first and second stop members, whereby said crank member can be freely returned to a predetermined rotated position for movement to a concealed position, irrespective of the rotative position of the drive member.
Claim 2
Dependent Claim
235 words
Movable vehicle panel member apparatus including a vehicle panel member and driving means for moving said panel member with respect to adjacent vehicle structure, said driving means including: a rotatable driving member which is drivingly connected to move said panel member in response to rotational movements of said driving member, said driving member having a first stop member, a shaft, a crank member drivingly connected to said shaft for applying rotational movement to said shaft, and a driving plate carried by said shaft, said driving plate having a second stop member engageable with said first stop member to rotate said driving member along with said driving plate, said first and second stop members occupying a small circumferential length of said driving member and driving plate so that said driving plate can be freely rotated from a first position with the second stop member engaging one circumferential side of said first stop member to a second position with the second stop member engaging an oppositely facing circumferential side of said first stop member, said shaft and said driving plate being connected by lost motion connecting means permitting free relative rotational movement corresponding to the angular range determined by the circumferential lengths of the first and second stop members, whereby said crank member can be freely returned to a predetermined rotated position for movement to a concealed position, irrespective of the rotative position of the drive member.
Claim 3
Dependent Claim
15 words
Apparatus according to claim 1, wherein said vehicle panel member is a roof panel member.
Claim 4
Dependent Claim
25 words
Apparatus according to claim 2, wherein said driving means includes means for tiltingly and slidingly moving said panel member with respect to adjacent vehicle structure.
Claim 5
Dependent Claim
17 words
Apparatus according to claim 3, wherein said driving member is a gear mounted loosely on the shaft.
Claim 6
Dependent Claim
77 words
Apparatus according to claim 4, wherein the shaft is provided with flattened areas in the vicinity of the driving plate, said flattened areas being on two opposite sides and parallel to one another, and wherein the driving plate is provided with an opening to accept the flattened areas of the shaft, said opening being so designed that it allows rotation of the shaft relative to the driving plate by the predetermined angular range in both rotational directions.
Claim 7
Dependent Claim
52 words
Apparatus according to claim 4, wherein the shaft is provided with a radially projecting pin in the vicinity of the driving plate, said pin extending into a recess in the driving plate, said recess corresponding to the desired amount of play, and with the ends of said plate constituting stops for pin.
Claim 8
Dependent Claim
77 words
Apparatus according to claim 1, wherein the shaft is provided with flattened areas in the vicinity of the driving plate, said flattened areas being on two opposite sides and parallel to one another, and wherein the driving plate is provided with an opening to accept the flattened areas of the shaft, said opening being so designed that it allows rotation of the shaft relative to the driving plate by the predetermined angular range in both rotational directions.
Claim 9
Dependent Claim
52 words
Apparatus according to claim 1, wherein the shaft is provided with a radially projecting pin in the vicinity of the driving plate, said pin extending into a recess in the driving plate, said recess corresponding to the desired amount of play, and with the ends of said plate constituting stops for pin.
Claim 10
Dependent Claim
224 words
Movable vehicle panel member apparatus including a vehicle panel member and driving means for moving said panel member with respect to adjacent vehicle structure, said driving means including: a rotatable driving member which is drivingly connected to move said panel member in response to rotational movements of said drivng member, said driving member having a first stop means, a shaft, a crank member drivingly connected to said shaft for applying rotational movement to said shaft, and transmission means carried by said shaft, said transmission means forming a second stop means engageable with said first stop means to rotate said driving member along with said transmission means, said first and second stop means being arranged so that said transmission means can be freely rotated from a first position with the second stop means engaging one circumferential surface of said first stop means to a second position with the second stop means engaging an oppositely facing circumferential surface of said first stop means, said shaft and said transmission means being connected by lost motion connecting means permitting free relative rotational movement corresponding to the angular range determined by the circumferential lengths of the first and second stop means, whereby said crank member can be freely returned to a predetermined rotated position for movement to a concealed position, irrespective of the rotative position of the drive member.
