Abstract:
A door closer includes a closer casing, a pivot unit, and a length-variable damping cylinder. The pivot unit includes a pivot axle, a cam member, and a cam follower member. The pivot axle has a drive end portion that extends into and that is retained rotatably in the closer casing, and a coupling end portion that extends out of the closer casing. The cam member is mounted co-rotatably on the drive end portion of the pivot axle. The cam follower member is disposed in the closer casing, and is acted upon by the cam member. The damping cylinder is disposed in the closer casing, and has one end coupled to the cam follower member and an opposite end anchored to the closer casing.
Abstract:
An overhead garage door having the appearance of a set of light-transmitting doors, such as French doors. The garage door includes arrays of light-transmitting panels on the door arranged to simulate light-transmitting doors, moldings, doorknobs, and hardware for connecting the garage door to a garage. The door may be formed from a plurality of sections arranged in a stack and pivotally connected to adjacent sections. The garage door may be formed from a kit having a plurality of door sections with light-transmitting panels mounted thereon and hinges for connecting the sections. The garage door may also be formed from a retrofit kit for modifying an existing garage door to have the appearance of a set of light-transmitting doors. The light-transmitting panels permit visible light to enter a garage and may be translucent. The panels may be made of polycarbonate acrylic.

Abstract:
A sliding door includes a frame comprising an elongated header member having a topwall, a backwall, an intermediate wall and a bottom wall. The bottom wall and intermediate wall are engageable with sliding door panel support rollers and the bottom wall and intermediate wall are interconnected by a separate support member to distribute door panel loads between such walls. A movable cover is attached to the header by a hinge part including spaced apart flanges and projections co-operable with projections on the header to support the cover in open and closed positions. The door operator is supported in the header by a single angle-shaped frame member supporting a power supply, a controller and a door operator motor. An adjustable torsion bar assembly supports the door panel against sagging.
Abstract:
An operator (10, 210) for moving in upward and downward directions a sectional door (D) having a counterbalancing system (30) including a drive tube (31) interconnected with the door comprising, a reversible motor (41), selectively driven in two directions by the motor, a driven gear (54) freely rotatably mounted on the drive tube and engaging the drive gear, a slide guide (56) non-rotatably mounted on the drive tube, a disconnect (70) mounted on the slide guide and selectively movable between a first position rotatably connecting the driven gear and the slide guide and a second position disconnecting the drive gear and the slide guide, and an actuator (80) for selectively moving the disconnect between the first position and the second position.
Abstract:
A sliding door system is provided which has a support frame including vertical posts and a horizontal transom. An assembly supporting a sliding door wing is supported at the support frame and includes a running mechanism operable to carry the door wing disposed in a running mechanism housing. A drive motor assembly disposed in a drive motor assembly housing is operably connected to the running mechanism to move the door wing. The running mechanism housing and the drive motor assembly housing are disposed one behind the other in a direction transverse to the transom and door wing and are configured and dimensioned to form a parallelepiped with a vertical height fitting within a vertical height of the transom.
Abstract:
The present application discloses a retrofit power door assembly for installation on a manual door assembly. One aspect of the application related to a retrofit power door assembly having an axial operator. Another aspect of the application relates to a retrofit power door assembly having a clutch with a manually engageable release member.
Abstract:
A hinged connection between a removable housing closure and a stationary housing part, wherein a terminal configuration of the housing closure has a convex molding, with a web that is contiguous with the molding and which web has a tapering cross section. Adjacent to the web there is an indentation, in which a convex molding that is on the stationary housing part and is offset at an angle of 90 degrees from a projecting leg and is connected to the projecting leg by a contiguous web that has a tapering cross section is engaged. The housing closure can thereby be pivoted with respect to the stationary housing part and re-engaged with it. Additionally, when the housing is closed, no parts project either inside or outside in the vicinity of the housing closure and the stationary housing part.
Abstract:
A manually releasable coupling device for connecting an elongate operator chain (2) with a frame or main frame member of a window comprises a first coupling member (3) for connection with a free end of the operator chain (2) and a second coupling member (6-10) designed for mounting in or on the frame or main frame member. The first coupling member is a flat disc-shaped element (3) with a substantially keyhole-shaped recess 85), while the second coupling member comprises a shaft section (6) for mounting in a bore in the frame member or the main frame member in connection with a turning handle (7). The shaft section (6) has a local constriction (8) for releasable engagement with the keyhole-shaped recess (5) in the disc-shaped element (3). In order to allow manual closing of the window under surmounting of sealing pressure, the shaft section may be eccentric relative to the rotational axis of the turning handle.
Abstract:
A safety edge assembly, for a movable closure such as a garage door, automatically reverses the direction of travel of the door when the door encounters an obstruction. The safety edge assembly includes an electrically conductive mounting rail fixed to the door, and a deformable tubular member supported on the mounting rail. A conductive member on the tubular member is movable, upon deformation of the tubular member, from a first position normally spaced from the conductive mounting rail into a second position in engagement with the conductive mounting rail to complete an electrical circuit for controlling the direction of movement of the door. An end plug for closing the open end of the tubular member has a nonconductive portion for insertion between the end of the conductive member, which may fray or otherwise move out of position while being cut to length in the field, and the end of the conductive mounting rail to provide electrical insulation therebetween. A method of controlling operation of a movable door includes the step of moving an electrically conductive member on a deformable member on a leading edge of the door into electrical contact with an electrically conductive mounting rail on the leading edge of the door, under the influence of forces applied to the deformable member by contact of the tubular member with an obstruction, to control actuation of the movable door.
