Abstract:
A hanger assembly for a sliding screen door comprises a horizontally mounted track that fits within a standard door header and roller assembly, preferably one roller assembly per side of the screen door. Each roller assembly comprises at least a roller, and preferably two per roller assembly, and a holder that connects the roller(s) to the screen door. The holder includes a connecting bar portion that attaches to the roller(s) and a generally U shaped bracket portion that extends downwardly from the connecting bar portion, whereby the screen door is positioned and held snugly within the U shaped portion. A side of the bracket U shaped portion includes a slot for vertically and/or horizontally adjusting the screen by positioning of attachment means through the slot such as a screw.
Abstract:
An assembly system for a medium powered door opening and closing device especially for sliding doors. The assembly consists of a supporting profile located above the doorway with grooves or corresponding guides which act as travel tracks for rollers or wheels that function as door suspending members. The assembly also includes one or more channels through the profile to conduct pressure medium to a cylinder and/or a valve system and a cylinder to move the door, which cylinder is placed parallel to and in association with the profile. There is at least one connection hole between a profile flow channel and the cylinder for moving the piston and the piston rod. The cylinder is connected to supporting members and a valve system to control the cylinder.
Abstract:
An insert is disclosed for use with a sliding panel door having a sash and rollers for supporting the door on a rail of a supporting frame. The insert is adapted to be secured to the sash in a vertically adjustable position and extend longitudinally between the rollers. When the sliding door is mounted on the rail, a portion of the insert surrounds the head of the rail and prevents the door from becoming dislodged from the rail by lateral forces. The insert also provides security against the sliding door being lifted and removed from the rail by an intruder. Furthermore, a weather strip can be secured to the insert to reduce air and water leakage under the door.
Abstract:
For the purpose of preventing a vehicle sliding door from falling off, a stopper member is fixedly secured to the vehicle body and a coacting surface is provided on a bracket mounted on the vehicle door. As guide rollers of the vehicle sliding door tilt under an external force applied to the vehicle door, the stopper member engages with the coacting surface and prevents the rollers from derailment. Since the stopper member extends laterally, it is effective for preventing the sliding door from falling off even when the sliding door is deformed.
Abstract:
A by-pass door assembly is disclosed including a pair of stiles and a pair of trim pieces adapted to frame a rectangular panel and a plurality of corner brackets held by the stiles and the trim pieces. Each of the stiles includes an elongated one-piece slot free member having spaced front and rear walls joined by a side wall to define a panel receiving channel. The rear wall and the side wall define a triangular box shaped portion. Each of the trim pieces includes a rear wall having a longitudinally extending, outwardly directed groove portion. Each of the corner brackets includes a central, channel-shaped housing and outwardly extending portions having spaced tabs adapted to be received and captured by the stile members. Tabs extend outwardly from the transverse edge of the bracket and include a transverse bead which is captured by the groove of the trim member. Brackets on one side of the panel are adapted to retain guide rollers to either suspend the door construction from an upper track or to support the door construction on the lower track. The remaining corner brackets carry guide members having flexible attachment tabs.
Abstract:
Apparatus is provided for supporting and drivingly opening and closing an overhead single-panel door such as a garage door. The apparatus includes drive rollers protruding from the plane of the door at respective opposite upper corners thereof, which drive rollers are bearingly supported by a plate member attached to the door. These drive rollers are supported from underneath and in driving contact with fixed guide tracks arranged at the building accommodating the door. In order to insure continuous firm driving engagement of the drive rollers with the topside of the guide track, a bearing bracket is rotatably supported at the drive roller axles, which bearing bracket in turn supports a pair of counterpressure rollers engageable directly at the underside of the guide track. The counterpressure rollers are spaced from one another in the direction of travel of the guide roller at respective opposite sides of a line through the axle with the drive roller and extending downwardly, such that at least one of these counterpressure rollers is continuously in supporting backing engagement with the guide track so as to assist in assuring a firm driving contact between the guide rollers and the guide track. In preferred embodiments, an additional spring support system is provided between the drive roller and the bracket supporting the drive roller axle and the door, so as to provide an additional biasing force in the downward direction on the drive roller. In preferred embodiments, the guide track is constructed as a C-shaped cross-sectional member, and the bearing bracket includes an extension which protrudes over the top of the guide track as a safety measure to support the door in the event of an axle breakage or the like.
Abstract:
A sliding door installation in a doorway. Framed door panels are guided over threshold trackways and suspended from roller wheels in trackways at the top of the doorway. Corner brackets interconnect rails and stiles framing the door panels. Identical brackets interchangeably utilizable to carry roller wheels or floating guides interconnect the rails and stiles at the corners of the door panels. The brackets include three spurred lugs for securing the brackets to the rails and stiles. The rails and stiles are designed to be interconnected by the brackets to form a sturdy frame around the door panel edges.
Abstract:
A unitary panel edging member is disclosed in which a first channel is formed with an inturned flange for gripping the edge of a panel of various thicknesses, such first channel being so adaptable without adversely affecting the outer walls of such edging member. The member includes a second channel for receiving a corner connector therein. When the member is in the stile, the second channel faces in the same direction as the first channel. When the member is the rail, the second channel faces in the opposite direction with respect to the first channel. A panel assembly including a rail and stile edging member and corner connector is also disclosed.
