Abstract:
A collapsible cable regulator assembly is provided, having a collapsible support structure wherein one or more swing arms are pivotably mounted to a lateral member. Cable guide means are provided for mounting a regulator cable, including a cable return at the free end of each of the swing arms. The collapsible support structure is openable from a collapsed condition in which each swing arm is at an acute angle to the lateral member, to an operating condition in which each swing arm is at an operating angle to the lateral member which is greater than the aforesaid acute angle. The cable regulator assembly in its collapsed condition has improved installation capability, being especially advantageous for installation through limited access openings. Once in proper location, the cable regulator assembly is opened to its operating condition. The regulator assembly can then be permanently or non-permanently mounted in position, and a windowpane or other moveable member attached to mounting brackets or gliders driven by the regulator cable. In the operating position the swing arms act as guide rails with good parallelism aided by the lateral member acting as an interconnecting cross-member between the guide rails.
Abstract:
A urethane coating composition is disclosed which uses fluorinated monohydric alcohols to increase abrasion resistance. One specific use of the coating is on vehicle sealing systems which use elastomeric substrates. The coating composition was found to have dramatically improved abrasion resistance in glass run channel applications over similar coatings without the fluorinated component.
Abstract:
The lifting door has slatted armor for closing the door aperture, the armor having hinge straps including hinge members connected to one another by pins for articulation of the straps relative to one another. The hinge straps are supported in guide tracks at the sides of the door aperture. The adjoining slats attached to the hinge members are spaced from one another and sealing strips extending approximately the entire door width afford a seal between the opposed registering opposite edges of adjoining slats.
Abstract:
A lifting door includes a plurality of slats pivotally connected one to the other for pivotal movement about horizontal axes. Each slat carries at opposite ends a guide. Guide tracks are disposed in a door aperture for guiding the door during opening and closing. The guide tracks above the door aperture extend in a generally inwardly directed spiral configuration whereby, upon opening the door, the slats are guided about the spirally configured guide tracks into an open position without engaging one another.
Abstract:
A one-piece glass run guide for retaining and smoothly guiding a slidable vehicle window includes a polymeric strip having a substantially U-shaped transverse cross section including a base, an inboard leg having a projecting lip portion which engages an interior surface of a slidable vehicle window, and an outboard leg having a projecting lip portion which engages an exterior surface of the slidable vehicle window. The glass run guide can be formed such as by injection or compression molding, extruded, or can be formed from a combination of molded and extruded portions. The one-piece glass run guide of the invention is formed of a fiber reinforced polymer having sufficient strength and rigidity to counter forces exerted by the sliding vehicle window to prevent undesirable inboard, outboard, forward and rearward movement of the window, while at least the surfaces of the lip portions which contact the surfaces of the slidable vehicle window are low friction, non-abrasive surfaces which facilitate smooth movement of the window as it is raised or lowered. The invention, therefore, performs, with a one-piece guide, two different functions which are conventionally performed by separate components.
Abstract:
A trolley rail system (10) for supporting and guiding a sliding cooler door (14) of a walk-in type cooler. The system has a guide rail (27) having two linear segments (29,30) and two deviation ramp portions (33,34), and an auxiliary rail (38). The system also has a leading trolley (41) and a trailing trolley (42). The leading trolley has a wheel (51) supported upon the guide rail. The trailing trolley has a primary wheel (52) supportable upon the guide rail and an auxiliary wheel (53) supportable upon the auxiliary rail.
Abstract:
A door drive of a up and over door, sectional side or sectional ceiling door or sliding door, especially of a garage door, comprises at least one cylindrical guide tube supported against a ceiling or side wall, has a slide carriage arranged for movement along the guide tube, an endless traction element and a drive for opening and closing the door. The carriage is connectable with the door panel via a connecting rod. The ends of the traction element are secured together by means of a turnbuckle. For better support of the guide tube and for sampler connection or coupling of the traction element with the slide carriage, a number of mounting brackets are secured to the upper side of each guide tube for receiving support struts for mounting in the guide tube to the garage ceiling or wall. The slide carriage slides with a tubular portion along the guide tube. It has a continuous longitudinal slit on its upper side so that it can pass the brackets. The slide carriage has furthermore a lateral coupling element which can releasably be coupled with the turnbuckle. The turnbuckle comprises opposedly arranged a left-handed threads and a right handed threads, respectively, at each end for receiving anchor screws at the ends of the traction element permitting tensioning of the traction element.
Abstract:
This invention relates to a friction drive mechanism for a motorized sliding door. The door is suspended by a first rail and its movement guided by a third rail. A second rail is flexibly coupled to the first and biased against a motorized driving roller by a simple tensioning mechanism. The tensioning mechanism maintains the friction contact between the driving roller and the second rail. The flexible coupling joining the first and second rails compensates for any misalignment in the mounting of the componentry. The flexible mounting also allows for the door to be driven around curves.
Abstract:
A wear resistant track for the rollers of an overhead door to roll against includes a pair of uniform longitudinally extruded members such as an insert and a channel and locking means for releasably interlocking the members together whereby a planar surface of the insert is flush with portions of the channel and positioned for the rollers to bear against. In one arrangement the insert was of a polymer such as nylon and the channel was of aluminum.
Abstract:
An overhead tracked door selfsealing device suitable for easy retrofit of existing door installations which have no self sealing feature. It is comprised of a bracket and a spring driven cam system that is attached to the door track at the roller shaft points when the door is in the closed position. As a result, a lateral force imparted by the cam against the roller shaft via the pre-loaded spring forces the door against the jamb.
