A roller tube including a body having a tube wall that defines an interior and an exterior. The body includes a first end and a second end opposite the first end. A surface feature is formed in the tube wall proximate the exterior. The surface feature is configured to receive a sheet material and is configured to deformably fix the sheet material to the tube wall. The surface feature maintains a circular profile in the tube wall proximate the interior.
A roller tube support mechanism includes a roller tube including a roller tube body. The roller tube is configured to support a sheet material wound around the roller tube body along a length of the roller tube body between a first end and a second end of the roller tube body. An assembly includes a first mount and a second mount opposite the first mount. The assembly is configured to support the roller tube rotatably coupled to the first mount and the second mount. A support cradle is coupled to the assembly between the first mount and the second mount. The support cradle is configured to support the roller tube along the length of the roller tube.
A roller tube housing includes a first housing portion and a second housing portion configured to lockingly engage with the first housing portion defining an interior and an exterior. A support cradle can be formed integral with the first housing portion. The support cradle can be configured to support the roller tube along a length of the roller tube. A dispensing passage for dispensing material from said roller tube.
Roller Tube Having External Slot For Mounting Sheet Material
A roller tube has a tubular wall and a longitudinal axis. A channel runs longitudinally in an exterior surface of the tubular wall and is configured to receive an attachment insert for sheet material such as a solar shade, movie screen, decorative shade or the like. The channel has first and second side walls that extend from an interior portion of the tubular wall toward the exterior surface. The second side wall extends further away from the longitudinal axis of the roller tube than the first side wall. This creates a lip in the exterior surface of the roller tube, enabling the attachment insert to be mounted flush with the exterior surface of the roller tube and avoiding any bumps from being formed in the sheet material as it is wound around the tube. The tube wall varies in thickness and has a relatively thick section to accommodate the channel being formed therein.
A support assembly is provided for a roller tube having a sheet material wound therearound. The support assembly has opposed first and second mounts adapted to support the roller tube, which is rotatably coupled to the mounts. At least one support cradle is disposed between the first and second mounts. The support cradle is configured to support the roller tube along a length thereof A biasing member is arranged to reduce a force of the roller tube in a direction toward the support cradle, thereby preventing the sheet material from binding against the support cradle as it winds and/or unwinds.
Spring Biased Slide Arrangement For Anti-Bow Roller Tube
A support assembly is provided for a roller tube that holds sheet material. The support assembly has opposed first and second mounts adapted to support the roller tube when rotatably coupled to the mounts. The mounts can include slides having a slide member that slides within a slide bracket. A support cradle is disposed between the first and second mounts. The support cradle is configured to support the roller tube along a length thereof. Various spring elements can be arranged to apply a force to the roller tube in an upward direction when the roller tube is positioned to dispense material therefrom in a downward direction, thereby preventing the sheet material from telescoping and/or from dragging or binding against the support cradle as it winds and/or unwinds, while also keeping the material from being wound tighter at the ends than across the rest of the roller tube.
Frame Assembly Using Master Rib With Positionable Cleats
A frame assembly, such as for an awning or canopy, includes a master rib having identical keyways running the longitudinal length of the rib. Each keyway is defined by an opposing pair of sidewalls extending lengthwise in the longitudinal direction. The sidewalls are each formed integrally with a plurality of threadlines extending in the longitudinal direction which face opposite from and are offset in the depthwise direction by a given pitch from those of the other sidewall, so as to form threadable surfaces for a screw to be threaded therein. A cleat member has a body portion with a depthwise bore so that a threaded screw can be inserted depthwise and project from its lower end into the keyway and the master rib. The cleat member can be fastened to the master rib at any position along its longitudinal length. The cleat member preferably has a mating cleat which projects from the lower end into the keyway, or brackets against the sides of the master rib wall, so as to guide and hold the cleat member firmly in position.
An awning support structure has lateral arms with shoulder ends which are pivotably mounted to load-adjusting mounting members secured to a mounting portion of a building. The load-adjusting mounting members allow the lateral arms to deflect in the upward or downward directions, in order to allow the awning structure to absorb and/or shed the load. The preferred mounting members have urethane compression joints securing the shoulder ends of the lateral arms to shoulder brackets fixed to a support tube which is secured to the building.
