Automobile protecting sun shade

Claim 2

In an automobile--an installation which comprises a casing affixed to the car's roof at its inside, four curtains to be contained in such casing, one for the windshield, two oppositely disposed ones for the sides of the car, and one for the rear window, the said curtains being provided with guiding members for their lateral edges, which guiding means travel in rails extending within the car along members supporting the roof of the car, pull ropes being attached to said curtains for moving them relative to the said casing, said pull-ropes being connected to springs at one end thereof, and drive means connected to the other end of each said pull-rope and being provided for moving the curtains, which drive means are operable from the interior of the car, said drive means including electrical motor means to simultaneously drive a plurality of said curtains, and means to selectively disconnect said drive means for one or more of said plurality of curtains, so that said electric motor acts on a lesser number of said curtains.

Claim 3

The arrangement of claim 1, characterized thereby that the said casing is a flat, box-like structure.

Claim 4

The arrangement of claim 2, characterized thereby that the said rails extend along from columns supporting the roof of the car.

Claim 5

The arrangement of claim 1, wherein said springs are spiral springs for pulling the curtains into the casing.

Claim 6

The arrangement of claim 1, characterized thereby that the motor is housed in the luggage compartment of the car.

Claim 7

In an automobile--an installation which comprises a casing affixed to the car's roof at its inside, four curtains to be contained in such casing, one for the windshield, two oppositely disposed ones for the sides of the car, and one for the rear window, the said curtains being provided with guiding members at their lateral edges, which guiding means travel in rails extending within the car along members supporting the roof of the car, pull-ropes being attached to the said curtains for moving them relative to the said casing, and drive means being provided for moving the curtains, which drive means are operable from the interior of the car, wherein the drive for the movements of the curtain comprises a motor fed with electrical current from the battery of the car, two first pulleys revolving in opposite directions being driven by the motor, pull-ropes winding on the said two pulleys, said ropes leading to a second pair of pulleys fixedly attached to a first pair of crown wheels, each of which meshes with one of a first pair of pinions which latter, over a common shaft, transmit rotational movement to a second pair of pinions, which--in turn--mesh with a third pair of pinions and transmit rotational movement to a fourth pair of pinions, each of which via second and third common shafts and a fifth and sixth pair of pinions transmit movement to third and fourth pairs of crown wheels which are fixedly connected each with a reel from which pull-ropes extend to side curtains, said second and third shafts carrying seventh and eighth pinions transmitting rotational movement to a fourth shaft and a pair of ninth and tenth pinions meshing with fifth and sixth crown wheels, each of which is associated with a reel from which pull-ropes extend to the frontal curtain of the arrangement.

Claim 8

In an automobile--an installation which comprises a casing affixed to the car's roof at its inside, four curtains to be contained in such casing, one for the windshield, two oppositely disposed ones for the sides of the car, and one for the rear window, the said curtains being provided with guiding members at their lateral edges, which guiding means travel in rails extending within the car along members supporting the roof of the car, pull-ropes being attached to the said curtains for moving them relative to the said casing, and drive means being provided for moving the curtains, which drive means are operable from the interior of the car, wherein the drive for the movements of the curtain comprises a motor fed with electrical current from the battery of the car, two first pulleys revolving in opposite directions being driven by the motor, pull-ropes winding on the said two pulleys, said ropes leading to a second pair of pulleys fixedly attached to a first pair of crown wheels, each of which meshes with one of a first pair of pinions which latter, over a common shaft, transmit rotational movement to a second pair of pinions, which--in turn--mesh with a third pair of pinions and transmit rotational movement to a fourth pair of pinions, each of which via second and third common shafts and a fifth and sixth pair of pinions transmit movement to third and fourth pairs of crown wheels which are fixedly connected each with a reel from which pull-ropes extend to side curtains, said second and third shafts carrying seventh and eighth pinions transmitting rotational movement to a fourth shaft and a pair of ninth and tenth pinions meshing with fifth and sixth crown wheels, each of which is associated with a reel from which pull-ropes extend to the frontal curtain of the arrangement.

Claim 9

The arrangement of claim 1, wherein said guiding means comprises an idler pulley located adjacent the bottom corner of each window, and said drive means comprises a driven pulley connected to the other end of each said pull-rope, and wherein each said pull-rope passes from said driven pulley down and around said idler pulley, then back upwardly to the curtain with which it is associated and through the guiding members of said curtain, and then to a said spring which is housed in said casing.

Claim 10

An arrangement in accordance with claim 1, wherein said selective means comprises a plurality of interacting gear wheels forming part of said drive means, and electromagnetic means for selectively moving one or more of said gear wheels out of engagement with another gear wheel.
