Abstract:
A centering device for centering a sliding door or window, including a rail; a moving member configured to be movable along the rail; and a plurality of centering rollers fixed to one of the rail and the moving member and spaced along a length thereof corresponding to a direction of movement of the door or window along the rail, the centering rollers abutting against an other of the rail and the moving member to laterally center the moving member with respect to the rail. The centering device can be implemented in a sill, header and jamb.
Abstract:
The present application discloses a sliding door comprising a door body, a supporting structure, a guiding structure, a lower sliding rail module and an upper sliding rail module, the supporting structure and the guiding structure are respectively fixed with the door body; the lower sliding rail module comprises first and second lower sliding rails; the upper sliding rail module comprises first and second upper sliding rails; when the door body, the first upper sliding rail and the first lower sliding rail are on the same plane, the door body is in a closed state, and when the door body, the second upper sliding rail and the second lower sliding rail are on the same plane, the door body is in an open state. Thus, the present application enables the door body to not occupy the width of the doorway in the open state.
Abstract:
The aim of the invention is to achieve a door closer arrangement (1) where the force needed for opening the door (2) is not so substantial. The invention comprises a door closer (6), a slide rail (7), and an arm (8) that connects the door closer with the slide rail. The arrangement comprises also a second rail (9), which is arranged to form a slide slope for the door closer (6).
Abstract:
In an upper door fitting of a sliding door which comprises a housing and two transverse guide rollers which each are rotatably supported each on a shaft stub, both shaft stubs extend parallel to each other and are arranged symmetrically with respect to a vertical longitudinal center plane. Both shaft stubs are rigidly mounted in the housing. In addition, the transverse guide rollers delimit an intake opening of the housing for guiding the sliding door so as to prevent impact noises and jerky movements of the sliding door.
Abstract:
A device comprising a guide having a first pair of substantially parallel running surfaces, which are placed along a first track at a lateral distance apart, and a second pair of substantially parallel running surfaces, which are placed along a second track at a lateral distance apart. The second pair of running surfaces extends, at a crossing or junction, transversely to the first pair of running surfaces. A carrier is displaceable over at least the running surfaces and has a bearing axle, extending transversely to the running surfaces, for fastening of a load, which bearing axle extends between the running surfaces. The device, close to the crossing junction, has a transport mechanism. The transport mechanism is movable between a take-up position in the first track, for load-bearing engagement with the carrier, and a delivery position in the second track, for release of the carrier. The invention further relates to a rail system and a transport mechanism.
Abstract:
A guide device for a folding door consisting of a carriage which is displaceably guided at a web part of a section rail and which surrounds the web part with rollers or slides. So that the guide device can easily be put into its longitudinally displaceable connection with the web part of the section rail from the side, the rear roller disposed behind the web part relative to the door is supported at an arm which is in pivoted connection with the carriage and which can be pivoted between an assembly position where it is pivoted out and a position of use where it is pivoted in, in which the rear roller contacts or almost contacts the front side of the web part.
Abstract:
A device is structured to be integrated with a major components such as a movable unit and a stator contained in a rail member for easy removal from downward of the lintel, thus eliminating adjustment work on site. Since the door may be simply installed on the hanger, it can be easily installed and removed. Also, the stator and the hanger with rollers may be connected by clamping a projection strip formed on a bottom face of the stator from left and right sides thereof with the hanger with rollers installed on the door, or instead by engaging the hanger with rollers with an engagement portion provided on the stator from both side thereof. Consequently, connecting and releasing of the stator and the hanger is simplified and the ease of maintenance is improved.
Abstract:
A hinge arrangement for hinging a sliding element (2) movable in guidance of, and carried by, a pair of fixed guide sections (1.sup.1, 1.sup.2) for turning about a hinge axle (3) affixed to the sliding element. The hinge arrangement comprises a first coupling member (4), connected to the hinge axle (3), and a second coupling member (5), connected to the guide section (1.sup.1, 1.sup.2), and the first coupling member and the second coupling member are arranged to become coupled with each other when the first coupling member is in register with the second coupling member, and thus to lock the hinge axle (3) relative to the guide section to be substantially immovable, for the turning of said sliding element.
Abstract:
A self-plumbing, counter-rotating trolley and track suspension system for supporting an operable wall panel is disclosed. The suspension system comprises a trolley assembly, including a pendant bolt to provide a common axle on which a pair of counter-rotating discs are rotatably mounted in spaced apart alignment. The track-contacting surface of each disc is spherically formed, with each surface generated from a common centerpoint but having unequal radii so that the surfaces generated by the radii have curvatures which are similar but are not congruent. The suspension system also includes a track having a pair of vertically spaced and diametrically arranged rails, each rail defining a cylindrical surface which is generated from the same common centerpoint of that of the discs, the locus of which lies above the rail-contacting surface of the upper disc. When the trolley is mounted for movement along the track, the discs of the trolley will always maintain mating contact with their respective rails, even when the center line of the trolley and track are in misalignment.
