The invention relates to a shade assembly which is used in vehicles and allows the shade to be retracted when it is released.
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.
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 a possible embodiment of the invention, the tube guiding member has a second grooved portion for attaching to an inner wall of the tube, and a protrusion for locating in the aperture. Thus, the tube guiding member is fixed to the inner walls of the wall.
In a possible embodiment of the invention, there is provided a housing having a housing passage for accommodating the tube. Thus, a housing which surrounds and protects the assembly is provided.
In a possible embodiment of the invention, the third cap has at least one connecting hole, and wherein at least one housing hole corresponding to the connecting hole is present on the housing, and wherein there is at least one connecting member for fixing the third cap to the housing. Thus, the assembly is fixed on the protective housing.
In a possible embodiment of the invention, the housing has a housing aperture allowing the shade to pass therethrough. Thus, an aperture is provided for the shade during extending and retracting processes.
In this detailed description, three different shade assemblies used in vehicles are described by way of examples only for better understanding the subject matter without limitation.
FIG.1 is an exploded view of a first assembly (1). The first assembly (1) generally has a tube (7) for winding a shade used in vehicles, a rod (9) disposed linearly within the tube (7), a first mounting member (12) through which said rod (9) is passed, a first spring (8) wound onto the rod (9), and opposing caps (4, 5) at which the ends of the tube (7) are located. A first cap (4) shown in the
In a preferred embodiment, said third cap recess (171) is circular in shape. At least one third cap flange (172) configured to be away from the cap is provided on the third cap (17). At least one third connecting hole (173) is provided on the third cap flange (172). There is provided a third cap extension (174) configured to be away from the third cap recess (171) and a circular wall (176) in said third cap recess (171). In a preferred embodiment, said wall is provided in a “C” shape. Further, a second slot (175) is provided on the third cap extension (174).
Assembly and operation of the first assembly (1) is as follows: The first spring (8) is wound onto the rod, 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 first spring (8) is attached to the first grooved portion (123) from the other side thereof. The first protrusion (91) of the rod (9) is passed through the guiding member hole (126). The rod (9) is disposed within the tube (7) along with the first spring (8) thereon. The rod (9) is placed in the second cap groove (52) of the second cap (5) 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). One end of the tube (7) is located within the guiding member channel (104). 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 second cap (5), and the housing hole (62). 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.
Assembly and operation of the second assembly (2) 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.
Assembly and operation of the third 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 (171) 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.
