Abstract:
The invention relates to a fixing element (7, 21) for fixing a guide rail (6) for sliding doors (1), in particular glass sliding doors, with a retaining piece (8) and a base piece (10, 23). The retaining piece (8) and he base piece (10, 23) are connected to each other in such a way as to be adjustable in the axial direction X-X relative to each other. The retaining piece (8) comprises a housing section (9), for fixing a guide rail (6). The base piece (10, 23) may be fixed to the furniture body (2), by means of, for example, a screw.
Abstract:
Guide track assemblies for upward acting doors include identical vertical and horizontal linear track sections and a curvilinear transition track section. The linear track sections include spaced-apart elongated slots formed at acute angles with respect to the longitudinal extent of the track sections for cooperation with retainer members mounted on angle-shaped jamb brackets. A header bracket also includes one or more retainer members thereon for disposition in similar elongated slots formed in the curvilinear track section. The linear track sections fit in telescoping relationship within enlarged end portions of the curvilinear track section. The configurations of the header brackets, jamb brackets and track sections facilitate quick assembly and easy positional adjustment of the track sections with respect to a door opening covered by a door guided by the track assemblies.
Abstract:
An elevator door sill assembly for use in elevator systems that have sliding doors. The door sill assembly comprises a sill plate, a support sill located below the sill plate having a rail that presents an inboard sliding surface and an outboard sliding surface. The assembly also comprises a first guiding surface that engages that inboard sliding surface and a second guiding surface that engages the outboard sliding surface. The assembly prevents that bottom of the elevator door from swinging while the door slides opened and closed. The sill assembly and guide system may be used with either hoistway doors or elevator car doors.
Abstract:
A universal overhead door system includes a pair of horizontal track members, a pair of vertical track members and a pair of track radius members interconnecting the horizontal and vertical track members. A pair of adjustable short radius members extend from the track radius members to guide uppermost rollers of an overhead sectional door. The overhead door system includes a pair of stationary sheaves positioned outboard of a pair of horizontal support rails which support the horizontal track members. A detent is provided at one end of the adjustable radius members to prevent undesirable travel the garage door. A spacer is provided for use in extension spring configurations when a long horizontal support rail is required. The spacer prevents metal-to-metal contact of moveable sheaves with the horizontal support rails.
Abstract:
A sectional door (2) is disclosed that includes a safety system. The safety system includes a shield apparatus (12), an improved support track (6), reverse angle track shields (80), and hemmed roller track edges (38) to prevent injury or harm to body parts errantly placed within or around the support track (6) during the opening or closing of the sectional door (2). The sectional door (2) includes a plurality of door sections (8) hingedly joined in an edge-to-edge relationship to form the completed sectional door (2). The sectional door (2) further includes support rollers (10) attached to the door sections (8), and a pair of support tracks (6), in which the support rollers (10) are confined. Each support roller (10) further includes a circular or rectangular roller shield (12) that is mounted to the axle (26) of the support roller (10) outside of the support track (6) where it is proximate the support track (6) in such a manner as to limit or prevent any fingers from engaging within the support track (6) with the support roller (10). The dimensions of the protective shield (12) are larger than the support rollers (10) so as to provide transport guidance within the support track (6) where track sections meet. The reverse angle track shields (80) are constructed of a solid metal piece so as to prevent objects from passing between the support track (6) and a mounting surface, with the outside edge being folded into a single hem (138) or covered with a protective material (140). The adjacent edge of the support track (6) is formed into a folded hem (38), either outwardly or inwardly, to prevent fingers from being cut.
Abstract:
A horizontal floor or roof structure having a plurality of spaced parallel joists each joist having a vertical web with upper and lower flanges extending from the web. Each flange has a free edge with a tubular bead extending along each free edge and having an elliptical cross-section wherein the minor axis is at least 20% of the major axis. A floor or roof member is supported over said metal joist. A preferred method of forming a horizontal reinforced concrete wall structure for a building includes mounting a wire mesh material over the upper flanges of the joists, and pouring concrete in a flowing condition onto the concrete forms over the mesh material and over the upper flanges of the joists so that curing of the concrete provides a horizontal reinforced composite concrete wall structure.
Abstract:
The invention concerns a window lifter with a guide rail (10) affixed on a base part (20) on a door inner panel, of an assembly carrier. The object of the invention is to provide a window lifter which is simple to adjust and prevents stressing of the window lifter system. This object is accomplished in that a seat (30) is formed on the base part (20), which seat is associated with a correspondingly shaped mating part (300) arranged on the guide rail (10), whereby the seat (30) and the mating part (300) are designed form-fittingly such that the guide rail (10) and the base part (20) are mounted tiltable relative to each other.
Abstract:
A door system for an enclosure such as a shower enclosure, including sliding doors suspended from hanging brackets which are attached to rails mounted to an opening of the enclosure. The hanging brackets include rollers which roll along the rails enabling the doors to slide with respect to the rails. The hanging brackets include anti-derailer clips snap fitted onto the brackets after the doors are hung from the rails to prevent the doors from being removed from the rails . The clips each have flexible catches at their top and bottom, as well as projections on a side to align their position with respect to the brackets.
Abstract:
An automotive door construction is configured so that a door trim 13 is divided into an upper trim 131 and a lower trim 132; a glass elevating mechanism 5 is installed on the inside surface of the lower trim 132 so that the upper end of a guide rail 7 projects upward from the upper edge of the lower trim 132; and the glass elevating mechanism 5 is inserted from the upper end of the guide rail 7 of the glass elevating mechanism 5 through a mount hole 2a in an inner panel 2, and is housed in a door bag portion 1b, and then the lower trim 132 is lowered along the inner panel 2, by which the glass elevating mechanism 5 and lower trim 132 are installed to the inner panel 2. By forming the relatively small mount hole 2a, which is shorter than the total length of the guide rail 7, in the inner panel 2, the modularized glass elevating mechanism 5 is incorporated in the door bag portion 1b. Therefore, the automotive door construction in which a modularized glass elevating mechanism can be incorporated without the formation of a large mount hole in the inner panel can be provided.
Abstract:
A window winder having a rail cable and motor. The motor drives the cable along the rail to move a window pane engaged on the cable. The rail (1) has a mounting on which a motor casing which houses the motor can be adjusted to a selected position and then securely fixed to the mounting. The motor that operates the cable is also fixed to the casing.
