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.
Abstract:
A back door hinge mounting structure comprising a pair of bolts connected with to each other at the central portion thereof and threaded at the opposed ends thereof, one end of the opposed ends connected to the roof panel with the other of the opposed ends to the fixed leaf of the back door hinge and a hinge cap for covering the mounting bolts which can be mounted and removed only when the back door is open, so that access to the mounting bolts with the back door closed is avoided.
Abstract:
Rotary drive, particularly for vehicle doors, in which the piston motion of a piston-power cylinder-unit 5 is converted into a rotary motion by means of roller pairs 14 which engage into oblique slots 10, 11. The oblique slots are provided in cylinders 4, 6 arranged coaxially inside each other and one of the cylinders is connected to the power output shaft 7. The slots exhibit an axial direction at their ends. Herein the cover 2 of a pot-shaped housing 1, through which cover the power output shaft 7 passes, exhibits a collar 15 projecting outwards and embracing the power output shaft. The power output shaft 7 is provided with a cup-type seal 17 seated firmly upon it, whose surface contour 18 overlaps outwardly the collar 15 and which with its edge 19 rests tightly at the cover 2. The cover is provided with an axially oriented groove 20 on its side facing away from the collar, into which groove the edge of the pot-shaped housing 1 is tightly fitted.
Abstract:
A decorative cover for mounting on butt-hinges to conceal the exposed portions thereof to improve the aesthetic appearance. The cover includes flap portions which are attached to the leaf members of the hinge to place an arcuate in cross section hump portion of the cover in overlaying relationship with the knuckles of the hinge. The decorative hinge cover is formed of an elastomeric material to allow it to conformingly move with the hinge.
Abstract:
A sliding door support assembly having a preassembled track assembly including a split cylindrical elongate track having a flat surface on the top and a number of mounting brackets secured to the flat surface at spaced intervals and a number of support members for supporting an elongate track cover, the support members being mounted on said track assembly after the door has been mounted in the track assembly and being selected to correspond to a particular type of track cover.
Abstract:
The closing mechanism of an automatic door closing arrangement is partly enveloped by an elongated unitary casing of sheet metal. Flanges on two of the longitudinal casing walls bound therebetween an opening in the casing which may be closed by a panel releasably retained by the flanges. Provisions are made for attaching the casing to a door and for linking the output element of the closing mechanism to a door frame. The panel may be removed simply and without tools for access to the mechanism or for replacement by another panel of different decorative appearance.
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.
