Abstract:
The present invention relates to sliding door systems, apparatus and methods of using and making the same. Specifically, the present invention relates to systems for opening horizontally sliding doors on a structure, such as, for example, a barn, warehouse, hangar, or other building or structure. Moreover, the present invention relates to apparatuses for providing the automatic opening of sliding doors. In addition, methods of making and using the same are provided.
Abstract:
Provided herein is a curb-mounted skylight having a rigid plastic curb frame, a mechanism for firmly securing the curb frame to an opening in a building, a transparent or translucent covering element, and a mechanism for retaining the covering element on the frame. The curb frame includes a fixed base frame (having an interior frame and a counter-flashing element) and a moveable sash frame (having an accessory shelf and a sash). The base frame and the sash frame may be connected to one another by a first hinge member integral with the counter-flashing element and a cooperative and complementary-shaped second hinge member attached to the sash. The hinge members form a watertight seal and may be disengaged to permit the sash to be removed from the skylight assembly during installation, if so desired. Because the frame and hinge components are made of plastic, the skylight assembly is relatively lightweight.
Abstract:
In one aspect, a method of operating a movable barrier operator includes engaging a flexible driven member with a drive of the movable barrier operator. The method includes moving the flexible driven member in a first direction to move a movable barrier connected to the driven member and monitoring the position of the movable barrier. In response to the movable barrier reaching a given position, the driven member is moved in a second direction without moving the movable barrier to remove slack from the driven member. In another aspect, a movable barrier apparatus includes a movable barrier controller operatively coupled to a movable barrier operator. The movable barrier controller is configured to cause the movable barrier operator to reverse direction of a flexible driven member a distance after stopping movement of a movable barrier toward a limit position and without moving the movable barrier.
Abstract:
A retrofit conversion kit for facilitating the conversion of a door operating apparatus conventionally mounted above the door, to a position mounted and anchored underground for operating a swinging door therefrom. The conversion to an anchored underground position is facilitated by incorporating positional adjustment mechanisms covering any or all possible adjustment dimensions.
Abstract:
Movable partition systems may include a chain guide structure extending along a curved path. The chain guide structure may have a specified maximum width, and may include attachment flanges that project laterally from a central beam beyond laterally outward ends of chain guide members of the chain guide structure by a specified minimum distance. Overhead support systems for movable partition systems may include such chain guide structures. Methods of forming overhead support systems and movable partition systems may include stretch forming a bent chain guide structure. Methods of installing overhead support systems and movable partition systems may include inserting fasteners at least substantially perpendicularly through attachment flanges of a chain guide structure to secure the chain guide structure to an overhead structure.
Abstract:
A guide rail assembly for moving a closure panel of a motor vehicle between an open position and a closed position includes a guide rail fixedly secured to the motor vehicle. A slide mechanism slidably engages the guide rail. A rod has one end coupled to the slide mechanism and an opposing end coupled to the closure panel to move the closure panel as the slide mechanism slides along the guide rail. A drive is fixedly secured to the guide rail for selectively driving the slide mechanism along the guide rail. A clasp is operatively secured to the slide mechanism for selectively coupling the drive to the slide mechanism such that the drive moves the slide mechanism along the guide rail to move the closure panel between the open and closed positions when the slide mechanism is coupled with the drive.
Abstract:
A folding leaf gate comprising a post hung section hingedly attachable to a gate post and at least one leaf hung section hingedly connected in series with the post hung section by means of one or more section hinges, wherein the folding leaf gate additionally includes a rotating device associated with the or each leaf hung section and sharing a common axis of rotation with the or each section hinge and secured in a static relationship to a leaf hung section whereby rotation of the or each rotating device causes rotation of a leaf hung section about the or each section hinge, and one or more translating devices engaging the or each rotating devices, the one or more translating device being configured, when in use, to translate rotational motion of the post hung section about a gate post to rotation of the one or more rotating devices whereby simultaneously to open a gateway closed by the folding leaf gate and fold the folding leaf gate in two or more.
Abstract:
The invention is a system for gearless operation of a movable barrier utilizing Lorentz forces, and in particular, a movable barrier operator retrofitted with a gearless motor capable of high torque at very low speeds. Eliminating a gear system in accordance with the present invention lowers maintenance requirements, increases efficiency, and streamlines operation of any movable barrier. By utilizing a motor which produces high-torque at low a speeds a system in accordance with the present invention does away with the need for complicated gears and pulley systems in order to achieve control of movable barriers. The present invention allows manufacturers, distributors and consumers to implement movable barrier systems with much more versatility and efficiency.
