In which case two holes are made in the sun shade screen and aligned in the path of the micro switches. The upper hole defines for the sensor the limit of the feedout while the lower hole defines the limit of the retraction. (The holes may also be used in an electro-optic sensor.) The present invention will be further described by figures 1-3. These figures are solely intended to illustrate the prefered embodyment of the present PAGE≡6≡ 115402/2 invention and not to limit the scope of the invention in any manner.
Figure 1 illustrates an isometric view of the electromechanical sun visor.
Figure 2 illustrates a cross section of an electromechanical sun visor unit.
Figure 3 illustrates an exploded cross section of an electro-mechanical sun visor unit.
Figure 1 illustrates an isometric view of the electromechanical sun visor. A control box (1), two sun visor units (2a) (2b), and a bi-directional electric (12v or 24v) motor (3) are shown linked together and their linkage and major components are forthwith elaborated.
The control box ( 1 ) contains a control panel ( ) , a sun shade screen up/down switch (5a) (5b), and a master on/off switch (6). The control box is connected by a wire (7) to a remote control unit or to the vehicle's alarm system. When the control box master switch is on and an up or down command is received either from the remote connection ( 7 ) or from the up/down switch ( 5 ) , then the appropriate polarity current is sent to the motor (3) and this current is stopped when either the sensor (18a) 115402/2 detects that the sun shade screen is raised to the level of the sensor, or when the sensor (18b) detects that the sun shade screen is lowered to the level of closure. The sensors (18a) (18b) are connected (9) to the control box.
Each of the two sun visor units (2a) (2b) includes a concealing container (20a) (20b) (for the take-up roller) for the sun shade screens (13a) (13b), an electromechanical axle (11a) (lib), and a rotational energy linkage (10a) (10b).
The transfer of rotational energy proceeds from the motor (3) through a flexible rotary cable (10a), through a rotary cable-to-axle attachment (25a), to an axle (lla) in the first sun visor unit, through a second rotational axle-to-cable attachment (25b), through a second flexible rotary cable (10b), through a third rotational cable-to-axle attachment (25c), and to a second axle (lib) in the second sun visor unit.
Each axle (lla) (lib) is enclosed in a rubber-like tube (12a) (12b). These rubber-like tubes are part of the frictional mechanism used to pull the sun shade screen up or down. The other part of the frictional mechanism are juxtaposed spring loaded (16a1) (16a'1) (16b») (16b'') rubber-like pulley (15a1) (15a") (15b1) (15b"). Between these juxtaposed rotating frictional members are the sun PAGE≡8≡ 115402/2 shade screens (13a) (13b). Each sun shade screen has flexible supporting strips running along the variable length sides (14a1) (14a") (14b') (14b''). These supporting side strips run between the juxtaposed frictional members . There is also an additional supporting strip along the middle of each sun shade screen (14a" · ) (14b' " ) .
Figure 2 illustrates a cross section of an electromechanical sun visor unit. The sun shade screen (13) has a flexible supporting strip (14) which runs between two juxtaposed rotating frictional members. One of the members is an axle (11) covered by a rubber-like tube (12). The other of the members is a rubber-like pulley (15) pressed into place by a spring like arm (16). The sun shade screen is rolled onto a take-up roller (17) which encloses a spring loaded axle (19). The sun shade screen is held to the take up roller by a longitudinally split cylindrical clip (17a) (not shown). This take-up roller is housed in a concealing container (20) which has a protective door (21), so as to protect the rotating components from contact with stray objects.
Figure 3 illustrates an exploded cross section of an electro-mechanical sun visor unit. Four level of enclosure are exposed wherein the spring loading take up assist mechanism (24) is inserted into the take-up roller PAGB≡9≡ 115402/2 (17) with its surrounding clip (17a), which is in turn located within the concealing container (20).
The spring loading take up assist mechanism (24) is comprised of a spring loaded axle (19) upon which is affixed one end of a co-axial spiral spring (22) and the other end of which is partially streched on and also wound around said axle (19), and this spiral spring is the affixed (23) at its other end, thus loading the mechanism (24) with an initial rotational potential energy.
This potential assists in the sun visor screen take up mechanism in two ways. First, when the sun visor screen is drawn from the take up roller by the powered frictional rollers (12) (15), the return potential is stored in the spring. Second, the initial loading of the spring provides a return potential for the last section of the sun visor screen to be returned. The spring loading take up assist mechanism (24) is inserted into the take-up roller (17).
On to the take-up roller is partially wound the sun shade screen (13) which is inturn held in place by the longitudinally split cylindrical clip (17a). This entire assembly (24) (17) (13) (17a) is in turn located within the concealing container (20).
PAGE≡1Q≡ 115402/2 Along side of and attached to the concealing container is the powered axle (11). In this preferred embodyment the rubber-like tube has been replaced with three sections of rubber-like tubing (12-1) (12-2) (12-3).
Note that since the two sun visor units are identical (except for the placement of the sensors), the motor may be attached either from the left side of the two joined units or from the right side of the two joined units.
