Abstract: The invention relates to a device for introducing and extracting drapery holding elements by hand or by means of an auxiliary rod in and out of an opening in the slideway of a drapery rod of a down-turned C-shaped cross-section, wherein the opening is closable by means of a removable insert piece and which comprises a channel for the drapery holding elements protruding from the channel through a slot formed between the angle portions of the C-form. The insert piece comprises a zone of C-shaped cross-section which is shorter than the opening, comprising at one end an extension insertable into the channel of the drapery rod under the angle portions thereof and comprising at the other end two elastic tongues extending the angle portions of the C zone and slidable under the angle portions of the drapery rod, the length of the C zone and tongues being greater than the length of the opening.

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.

Abstract: The invention relates to a device for attaching the vertical slats of a slatted blind to another element for support, in which an end of each slat is inserted into a cap like member having inwardly directed suspension lugs which support the slat by engagement in holes through the slat which are spaced from but adjacent to the end edge of the slat.

Abstract: Preassembled self-locking guide and pivot pin cartridge assemblies are installed on the job site in folding doors rather than on the factory assembly line. Considerable labor is saved in manufacturing and a better installation is achieved. Both the guide and pivot pin assemblies feature molded nylon housings which conveniently snap into place on the folding door brace structure. Top and bottom guide pin assemblies are identical and interchangeable. A lower adjustable pivot pin assembly possesses more than one and one-half inch of full threads on the molded nylon housing and includes a hardened steel lock clip having snap on engagement with the housing and threaded engagement with the adjustable screw-threaded pivot pin. A cooperating lock nut is provided to secure the assembly after proper adjustment. Both of the guide and pivot pin cartridge assemblies are insertable as units on the doors and can be removed if necessary.

Abstract: Two parallel rails for the guidance of rollers or sliders on opposite edges of a panel, door or similar structural component comprise each a pair of elongated, substantially parallel members nestedly interfitted with a longitudinal internal clearance left therebetween to allow a change of their transverse separation and/or a limited relative tilting thereof. For this purpose the two members are joined to each other, at longitudinally spaced locations, by a plurality of adjustable connectors each comprising a male threaded element or bolt and a female threaded element or nut, each of these elements being anchored to a respective member. One member serves as a base, to be fixedly secured to a support, and the connector elements anchored thereto are nonrotatably held therein; the other member, forming a track, has a guide channel with an apertured bottom giving access to slotted or otherwise indented faces of the coacting connector elements to enable their rotation by a suitable tool such as a screwdriver.

Abstract: A stop for limiting the upward movement of closures such as slidable windows and doors, which stop has a body portion adhesively securable to the frame of said window or door and limiting the upward movement of said window or door within said frame.

Abstract: A sliding door is suspended from a top rail for movement across a doorway and is guided at the bottom by a J-shaped rail mounted to the side of the building adjacent the doorway and extending upwardly into a downwardly opening channel provided along the bottom of the door.

Abstract: This invention relates to clamping apparatus defining a base plate having a male portion located at the first end and a female portion located at the second end. The base plate is adapted with apertures. First clamp plates are positioned longitudinally along each side of the base plate. The first clamp plates having a male portion located at the first end and a female portion located at the second end. The first clamp plate is adapted with first apertures that are in matching relationship with the apertures of the base plate and the first clamp plates have second apertures. Second clamp plates are positioned longitudinally along one side of the first clamp plates. The second clamp plates have a female portion located at the first end and a male portion located at the second. The second clamp plate is adapted with apertures in matching relationship to the second apertures of the first clamp plate.

Abstract: A door-supporting system for a multipanel, side-opening door includes a single track from which each panel is supported.

Abstract: An insulating system for reducing heat loss from a structure during one part of the day and for permitting light to enter the structure during another part of the day, this system comprising a roll mounted on the structure, a flexible sheet of material wound around the roll, structure supporting the roll immediate its length and engaging portions of the wound sheet, and means for unwinding the sheet from around the roll and deploying it in a plane and for rotating the roll to rewind the sheet therearound; and a system for detecting build-up of snow or ice.

Abstract: An assembly of a track member for suspended doors designed for ceiling or door opening header mounting having a separate fascia member mechanically interlocking therewith and secured in place and laterally supported by a spring member.
