Abstract
Abstract A drive apparatus of a roof structure for a vehicle comprises a drive gear rotatably supported by a casing of the apparatus; a first gear for transmitting the power from the drive gear to a drive section for opening and closing a lid disposed in the roof structure; a rotary member having a control section for switching a switch for detecting the position of the lid; and a second gear for transmitting the power from the drive gear to the rotary member. The drive apparatus has a control device for controlling a drive motor for driving the roof structure. The control device comprises a drive motor for slidably and tiltably driving the lid disposed in a roof opening by the normal and reverse rotations of the motor; a tilting control circuit having first and second tilting contacts disposed in a first switch, and tilting the lid by driving the drive motor in the normal and reverse directions by switching the first and second tilting contacts when the first switch is operated; a sliding control circuit having first and second sliding contacts disposed in a second switch, and sliding the lid by driving the drive motor in the normal and reverse directions by switching the first and second sliding contacts when the second switch is operated; and a switch device for electrically connecting and disconnecting the tilting control circuit and the sliding control circuit by a cam rotated by the drive motor in the normal and reverse directions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
238 words
A drive apparatus of a roof structure for a vehicle, said apparatus comprising: a positionable lid disposed in the roof structure; a drive gear system rotatably supported by a casing of the apparatus; a first transmission gear drive means for opening and closing the lid; switch means having a plurality of switches stacked with respect to each other and attached to the casing by attachment means; a second transmission gear control means including a rotary member having a plurality of stacked rotary control surfaces thereon, each surface in controlling contact with a respectively positioned one of the switches for switching the switches to detect the position of the lid, said plurality of control surfaces being disposed in upward and downward positions of the outer circumferences of the rotary member such that positions of all of the switches are completely adjusted by determining only one of the positions thereof at the attachment means; a motor; a main gear and a main shaft, disposed in said drive gear system; and means for connecting the motor, the main gear and the main shaft; wherein said motor being connected to drive the main shaft through the main gear, said first and second transmission gear means being driven by the motor through said means for connecting; said rotary member being disposed such that the rotary member does not overlap and does not underlap the main gear and the first transmission gear drive means.
Claim 2
Dependent Claim
238 words
A drive apparatus of a roof structure for a vehicle, said apparatus comprising: a positionable lid disposed in the roof structure; a drive gear system rotatably supported by a casing of the apparatus; a first transmission gear drive means for opening and closing the lid; switch means having a plurality of switches stacked with respect to each other and attached to the casing by attachment means; a second transmission gear control means including a rotary member having a plurality of stacked rotary control surfaces thereon, each surface in controlling contact with a respectively positioned one of the switches for switching the switches to detect the position of the lid, said plurality of control surfaces being disposed in upward and downward positions of the outer circumferences of the rotary member such that positions of all of the switches are completely adjusted by determining only one of the positions thereof at the attachment means; a motor; a main gear and a main shaft, disposed in said drive gear system; and means for connecting the motor, the main gear and the main shaft; wherein said motor being connected to drive the main shaft through the main gear, said first and second transmission gear means being driven by the motor through said means for connecting; said rotary member being disposed such that the rotary member does not overlap and does not underlap the main gear and the first transmission gear drive means.
Claim 3
Dependent Claim
22 words
A drive apparatus as claimed in claim 1, wherein said control surfaces are projected from an outer circumference of the rotary member.
Claim 4
Dependent Claim
30 words
A drive apparatus claimed in claim 1, wherein said lid is tilted and slidably moved by the first transmission gear drive means so as to open and close the lid.
Claim 5
Independent Claim
298 words
An apparatus for driving a roof structure of a vehicle, said apparatus comprising: a positionable lid disposed in the roof structure; a drive gear system rotatably supported by a casing of the apparatus and having: a first transmission gear drive means for opening and closing the lid; switch means having a plurality of switches stacked with respect to each other and attached to the casing by attachment means; a second transmission gear control means including a rotary member having a plurality of stacked rotary control surfaces thereon, each surface in controlling contact with a respectively positioned one of the switches for switching the switches to detect a position of the lid, said plurality of stacked control surfaces being disposed in upward and downward positions of the outer circumference of the rotary member such that positions of all of the switches are completely adjusted by determining only one of the positions thereof at the attachment means; a drive motor for slidably and tiltably driving the lid in response to rotations of the drive motor; a tilting control circuit having first and second tilting contacts disposed in a first one of said switches, and operative for tilting the lid by directionally driving the drive motor by switching between the first and second tilting contracts when the first one of said switches is operated; and a sliding control circuit having first and second sliding contacts disposed in a second one of said switches, and operative for sliding the lid by directionally driving the drive motor by switching between the first and second sliding contacts when the second one of said switches is operated, wherein said rotary member being disposed such that the rotary member does not overlap and does not underlap the main gear and the first transmission gear drive means.
Claim 6
Independent Claim
298 words
An apparatus for driving a roof structure of a vehicle, said apparatus comprising: a positionable lid disposed in the roof structure; a drive gear system rotatably supported by a casing of the apparatus and having: a first transmission gear drive means for opening and closing the lid; switch means having a plurality of switches stacked with respect to each other and attached to the casing by attachment means; a second transmission gear control means including a rotary member having a plurality of stacked rotary control surfaces thereon, each surface in controlling contact with a respectively positioned one of the switches for switching the switches to detect a position of the lid, said plurality of stacked control surfaces being disposed in upward and downward positions of the outer circumference of the rotary member such that positions of all of the switches are completely adjusted by determining only one of the positions thereof at the attachment means; a drive motor for slidably and tiltably driving the lid in response to rotations of the drive motor; a tilting control circuit having first and second tilting contacts disposed in a first one of said switches, and operative for tilting the lid by directionally driving the drive motor by switching between the first and second tilting contracts when the first one of said switches is operated; and a sliding control circuit having first and second sliding contacts disposed in a second one of said switches, and operative for sliding the lid by directionally driving the drive motor by switching between the first and second sliding contacts when the second one of said switches is operated, wherein said rotary member being disposed such that the rotary member does not overlap and does not underlap the main gear and the first transmission gear drive means.
