Abstract: A roller shade having a counterbalancing assembly with an optimally pretensioned spring that lowers the torque load on the motor of the roller shade throughout the rolling up or rolling down cycles. The roller shade comprises a roller tube, a gudgeon pin having a first stop, a gudgeon body having a through bore and rotatably connected about the gudgeon pin and operably connected to the roller tube, a limit nut operably connected to the gudgeon body and adapted to axially travel along the gudgeon pin within the through bore, a spring, a first spring carrier connected to the first end of the spring and operably connected to the gudgeon pin, and a second spring carrier connected to the second end of the spring and operably connected to the roller tube. The spring is pretensioned and the limit nut abuts the first stop thereby locking the pretension.

Abstract: Presented is a gudgeon assembly that includes a gudgeon body, a first ball bearing, a second ball bearing, a gudgeon pin, a first spring plate, a second spring plate, and two springs. The gudgeon pin extends through the gudgeon body and is coaxial with the first and second ball bearings. The first spring plate is coupled to a distal portion of the gudgeon pin. The second spring plate defines an opening and is coupled to the second ball bearing. The opening is coaxial with the second ball bearing and the gudgeon pin. The two springs are coupled to the first spring plate and the second spring plate. Longitudinal axes of the two springs are coplanar and non-coaxial with the longitudinal axis of the gudgeon pin. The gudgeon pin, the first spring plate, and the second spring plate rotate together as a single unit and rotate independently of the gudgeon body.

Abstract: A sunshade includes a roller, a screen wound on the roller, a torque unit, and a latch unit. The torque unit is mounted in the roller, extends outwardly of the roller, and is disposed for urging movement of the screen to a wound state. The latch unit includes a plug disposed in the roller and formed with a pin hole, a pin member, and a biasing member disposed in the roller. The pin member has a main portion (521) extending movably through the pin hole, a diameter-enlarged portion disposed in the roller and connected fixedly to the main portion, and a shoulder portion formed between the main portion and the diameter-enlarged portion and biased by the biasing member to abut resiliently against the plug.

Abstract: In order to facilitate mounting of a roller blind one end of the roller blind tube is fitted with a spring-loaded insert (M). To prevent this from being pushed back a grub screw may be used, but it requires tools and precise alignment. According to the invention a releasable pawl-and-ratchet structure (2, 4) is provided in the end plug (1). The release is obtained by rotating the holder (5) of the pawls (2), whereby they are directed into axial grooves (3 or 3?).

Abstract: A length adjustable fitting for blind systems, including a housing and a drive member fitted to said housing; a core component including a core member shaped for engaging a drive portion of said drive member, the core component including a support portion shaped for engaging a support member for supporting said fitting; wherein, the selective adjustment of the drive member relative to the housing moves the core member along an axis to a different position relative to the housing, wherein at each said position, the drive member engages the core member to resist movement of the core member along the axis from said position relative to said housing.

Abstract: The present invention relates to a roller blind idle end assembly for roller blinds comprising a splined bush, a support bearing and an end pin, wherein the splined bush is supported by the support bearing and rotatable relative thereto in use; the end pin projects from the support bearing and is slidably coupled thereto such that the end pin is adapted to move axially relative to the support bearing and projects therefrom to engage with a receiving element of a mounting bracket; and wherein the end pin is rotationally fixed relative to the support bearing. This assembly reduces wear between an idle end pin and an idle end bracket and the likelihood of failure of the blind.

Abstract: A roller blind tube with fabric wound around it is mounted in brackets that have spade-shaped elements (3) provided in the axis. These elements cooperate with oblong holes (2) in terminating plugs (1) in the roller blind tube. According to the invention the oblong holes (2) are opened by rotating excentrically built rings (8). Hereby the roller blind may be hung on the brackets, whereupon the rings (8) are closed again.

Abstract: A system for the deploying and storing of an automobile cover. The system is provided with a roller assembly which can be made to be pivotally disposed about the axis of an axle. Attached to the roller at one end and the axle at another end is a spring means. The roller assembly has attached to it a full body automobile cover. The cover having one end adapted to covering and being secured to the end of the automobile opposite from the trunk, and the other end attached to the roller. The cover wound around the roller assembly and the roller assembly is stored in the trunk compartment of the automobile. The cover can be easily unwound from and wound back onto the roller with the assistance of the spring biased roller. The operator can quickly deploy the cover by pulling it from the back of the trunk over the trunk lid, and over the car, securing it to front bumper. The trunk can be closed after the cover is secured to the front bumper, thus securing the system inside the trunk.

Abstract: A window shade motor and a window shade roller assembly which is characterized by easier release and release with greater certainty, as contrasted to current construction, while having fewer parts which is based, in part, on arranging the pivot axes of the pawls closer to the center and a reduction of parts to as few as seven including a cage structure which performs several functions and which may easily be formed by progressive stamping.

Abstract: A roller assembly fitting device for selectively locking the retraction of the pivot, which is inserted in a bore in a mounting bracket to support the roller assembly in both brackets. The device has a roller-end sleeve fixed to the roller assembly, a guide sleeve rotatably mounted in the roller-end sleeve, a pivot retractably mounted in the guide sleeve, and a coil spring interposed between the guide sleeve and the pivot to bias them in opposite directions. The guide sleeve has its radial projection for selectively fitting engagement with axial and peripheral grooves formed in the outer periphery of the pivot. The pivot is retractable when the guide sleeve is in the first position in which the projection is in the axial groove but locked when the guide sleeve is in the second position in which the projection is in the peripheral groove.

Abstract: A roller shade braking mechanism of the type including a pair of outwardly biased braking shoes for engaging a cylindrical brake drum. The brake shoes are urged into braking engagement by an axially positionable wedge which cams against the interior surfaces of the brake shoes to thereby produce a constantly applied braking force. Externally accessible adjustment means are also provided for adjusting the pressure exerted by said brake shoes.

Abstract: A window shade support roller having an improved spring motor construction and method of manufacture includes a spring retaining structure which holds a driving spring and a spear structure having an integral spear. The spear structure and the spring retaining structure cooperate together, and with a ball, to form a ball clutch mechanism. The spring retaining structure has ball-receiving recesses with canting floors which simplify assembly. Assembly steps include inserting balls into the spring retaining structure, inserting the spear structure into the spring retaining structure, inserting a dowel into the spear structure, positioning a spring around the dowel, and inserting one end of such spring between portions of the spring retaining structure, which uniquely capture and retain the end without other securement, for torsional winding of the spring.
