APERTURE ARRANGEMENT USED IN VEHICLES

Description

TECHNICAL FIELD

[0001] The invention relates to a shade assembly which is used in vehicles and allows the shade to be retracted when it is released.STATE OF THE ART

[0002] In the state of the art, shade assemblies are known, which are used in vehicles and allow the shade to be retracted. In such shade assemblies, the number of parts in the mechanisms for retracting the shade is rather high, and hence its assembly is difficult and the cost of manufacture is high. Further, the costs are much higher in these mechanisms, in the case that the rotational movement required for retracting the shade is provided by drive members. Therefore, there is a need for solutions which have lesser parts, is easy to assembly and have reduced cost of manufacture such that the shade is enabled to retract in the vehicles.

[0003] Patent Application US 2016 / 0083998 discloses a roller shade assembly a cylindrical tube having an inner surface defining an axial bore; a spindle including an outer threaded portion defining a helical groove, the spindle being configured to be received in the axial bore of the cylindrical tube for axial movement in the cylindrical tube at one end of the cylindrical tube; and at least one tracking element operatively associated with the cylindrical tube, the at least one tracking element being configured for riding in the helical groove to convert axial rotation of cylindrical tube into axial movement of the cylindrical tube on the support tube. The tracking element engages the helical groove from a position proximal to one end of the cylindrical tube. The starting axial position of the cylindrical tube in relation to the support tube is configured to be adjustable by manually rotating the spindle without rotating the support tube.

In the first assembly (1) thus mounted, energy is accumulated in the first spring (8) by the rotational movement of the tube (7). The energy accumulated in the first spring (8) is used to retract the shade by rotating the tube (7) in the opposite direction.

[0017] Assembly and operation of the second assembly (3) is as follows: The second spring is positioned between the spring fixing member (16) and the third cap (17) on the tube. The second spring (13) is fixed by being attached to the first slot (161) on the spring fixing member (16) from one end thereof and to the second slot (175) on the third cap (17) from the other end thereof. The tube guiding member (15) is provided at both ends of the tube (7) and the third cap extension (174) of the third cap (17) is passed through the tube guiding member channel (151). The protrusion (154) is located at the aperture of the tube. The tube (7) is located at the second slot (171) by the circular wall (176) from both ends thereof. The system thus mounted is placed in the housing channel (61) and fixed by at least one connecting member (19) through the third cap connecting holes (173) on the third caps (13), and the housing hole (62). In the first assembly (1) thus mounted, energy is accumulated in the second spring (13) by the rotational movement of the tube (7). The energy accumulated in the second spring (13) is used to retract the shade by rotating the tube (7) in the opposite direction.

Figure 24 is an exploded view of mentioned further embodiment of the invention and Figure 25 is an sectional view of said further embodiment. Figure 26 and Figure 27 are views of the fourth cap (18). The fourth cap (18) is cylindrical in shape. A fourth cap recess (181) is provided on the fourth cap (18). In a preferred embodiment, said fourth cap recess (181) is circular in shape. A circular ridge (183) is provided in said fourth cap recess (181). There is provided a fourth cap channel (182) extending along the fourth cap (18) from the ridge (183). In addition, a corresponding threaded portion (184) is provided on said ridge (183) on which a corresponding thread is present. At least one fourth cap flange (185) configured to be away from the cap is provided on the fourth cap (18). At least one fourth connecting hole (186) is provided on the fourth cap flange (185).

In a more detailed embodiment, the threaded portion (147) and the corresponding threaded portion (184) are complementary to each other. On the other hand, there is provided an extension (144) extending horizontally away from the second mounting member (14) on the first surface (142). There is provided a second mounting member channel (145) on a second surface (143) corresponding to the first surface (142). In a preferred embodiment, said second mounting member channel (145) has a "C" shape. There is provided a hole (146) which is located on the second surface (143) of the second mounting member (14) and is extended along at least part of the second mounting member body (141).

[0019] Assembly and operation of the further embodiment of the invention is as follows: The first spring (8) is wound onto the rod (9), and the first spring (8) is attached to the second protrusion (92) of the rod (9) from one side thereof and is fixed to the head (11). The rod (9) is inserted into the hole (146) from the other side thereof, whereas one end of the tube (7) is positioned in the second mounting member channel (145). The extension (144) is passed through the fourth cap channel (182). In such case, threads of the corresponding threaded portion (184) and the threaded portion (147) are complementarily integrated. The rod (9) is disposed within the tube (7) along with the first spring (8) thereon. The rod (9) is passed through the fourth cap (18) from one side thereof such that it will not rotate and is positioned in the guiding member (10) from the other side thereof. The guiding member (10) is positioned in the first cap groove (42) of the first cap (4). The system thus mounted is placed in the housing channel (61) and fixed by at least one connecting member (19) through the connecting holes (44, 54) on the first cap (4) and fourth cap (18), and the housing hole (62). The corresponding threaded portion (184) and the threaded portion (147) are disengaged by a force applied linearly to the extension (144). In the first assembly (1) thus mounted, energy is accumulated in the first spring (8) by the rotational movement of the tube (7). The energy accumulated in the first spring (8) is used to retract the shade by rotating the tube (7) in the opposite direction.REFERENCE NUMERALS
