Claim 3

The lifter apparatus of claim 1 wherein: the aperture in the attachment member is an elongated slot; and the link includes a slider member connected to tne second end thereof and adapted to slidingly engage the slot in the attachment member.

Claim 4

The lifter apparatus of claim 1 wherein the cam block and the attachment member are formed with complimentary engaging cam surfaces.

Claim 5

The lifter apparatus of claim 3 wherein the cam surfaces have a planar inclined form.

Claim 6

The lifter apparatus of claim 1 wherein the cam block is vertically adjustable with respect to the guide shoe.

Claim 7

A pivotal-sliding roof panel apparatus adapted to be mounted to the stationary roof structure of a vehicle having an opening in the roof which is opened and closed by a movable roof panel, the apparatus comprising: a housing adapted to be mounted to the stationary roof structure of the vehicle, the housing having an aperture adapted to register with the opening in the roof of the vehicle; a roof panel slidably mounted within the housing; guide rails mounted on the housing and extending in the sliding direction of the roof panel; front and rear guide shoes operatively connected to the roof panel and movable along the guide rails for moving the roof panel between a closed position wherein the roof panel is disposed in registry with the edges of the roof opening and an open position wherein the roof panel is disposed beneath the stationary roof structure of the vehicle; first and second lifter means, connected between the rear guide shoes and opposed sides of the roof panel, for moving the roof panel between a closed position and a lowered position wherein the roof panel is movable beneath the stationary roof structure of the vehicle and between the closed position and a vent position wherein the rear edge of the roof panel is raised above the stationary roof structure of the vehicle; each of the first and second lifter means comprising: a link having first and second ends, the first end of the link being pivotally connected to the rear guide shoe; an attachment member attached to the roof panel, the attachment member having an aperture formed therein; the second end of the link being slidably disposed within the aperture in the attachment member; a cam block mounted on the rear guide shoe, the cam block engaging the attachment member as the rear guide shoe moves along the guide rail and urges the attachment member and the roof panel upwards, pivoting the link about the first end; and wherein: further movement of the rear guide shoe causes further pivotal movement of the link about the first end and urges the roof panel upward from the closed position to the vent position.

Claim 8

A pivotal-sliding roof panel apparatus adapted to be mounted to the stationary roof structure of a vehicle having an opening in the roof which is opened and closed by a movable roof panel, the apparatus comprising: a housing adapted to be mounted to the stationary roof structure of the vehicle, the housing having an aperture adapted to register with the opening in the roof of the vehicle; a roof panel slidably mounted within the housing; guide rails mounted on the housing and extending in the sliding direction of the roof panel; front and rear guide shoes operatively connected to the roof panel and movable along the guide rails for moving the roof panel between a closed position wherein the roof panel is disposed in registry with the edges of the roof opening and an open position wherein the roof panel is disposed beneath the stationary roof structure of the vehicle; first and second lifter means, connected between the rear guide shoes and opposed sides of the roof panel, for moving the roof panel between a closed position and a lowered position wherein the roof panel is movable beneath the stationary roof structure of the vehicle and between the closed position and a vent position wherein the rear edge of the roof panel is raised above the stationary roof structure of the vehicle; each of the first and second lifter means comprising: a link having first and second ends, the first end of the link being pivotally connected to the rear guide shoe; an attachment member attached to the roof panel, the attachment member having an aperture formed therein; the second end of the link being slidably disposed within the aperture in the attachment member; a cam block mounted on the rear guide shoe, the cam block engaging the attachment member as the rear guide shoe moves along the guide rail and urges the attachment member and the roof panel upwards, pivoting the link about the first end; and wherein: further movement of the rear guide shoe causes further pivotal movement of the link about the first end and urges the roof panel upward from the closed position to the vent position.

Claim 9

The roof panel apparatus of claim 6 wherein: the aperture in the attachment member is an elongated slot; the link includes a slide member connected to the second end and extending outward therefrom, the slide member adapted to slidingly engage the slot in the attachment member.

Claim 10

The roof panel apparatus of claim 6 wherein the cam block and the attachment member have complimentary formed engaging cam surfaces.

Claim 11

The roof panel apparatus of claim 8 wherein the cam surfaces have a planar, inclined form.

Claim 12

The roof panel apparatus of claim 6 wherein the cam block is vertically adjustable with respect to the rear guide shoe.

Claim 13

The roof panel apparatus of claim 6 further including: means for preventing premature raising of the roof panel before the roof panel is situated below the roof opening.

Claim 14

The roof panel apparatus of claim 11 wherein the means for preventing premature raising of the roof panel comprises: a projection formed on the link and extending outward therefrom; the guide rail having a channular configuration defined by a base, spaced sides and inwardly upper flanges; the projection being disposed below the upper flange of one of the guide rails during movement of the roof panel between open and closed position so as to prevent premature raising of the roof panel; and the one guide rail having a discontinuity formed in the upper flange, the discontinuity being positioned such that the projection on the link can pass therethrough when the roof panel is below the roof opening so as to enable the roof panel to be raised to the closed position.

Claim 15

The roof panel apparatus of claim 6 further including: means for preventing removal of the roof panel from the exterior of the vehicle when the roof panel is in the closed position, the means for preventing removal of the roof panel comprising: a member mounted on the guide rail and having an upwardly extending side wall and an inwardly extending upper flange; a projection formed on the link and extending outward therefrom; the bracket being positioned such that the upper flange is disposed vertically over the projection on the link when the roof panel is in the closed position to prevent vertical upward movement of the roof panel therefrom.
