Abstract:
Prefabricated foldable building units are described that have one or more of the following advantages. They are more easily prefabricated, more easily transported to building sites without requiring special permits, unloadable and unfoldable at the building sites without using cranes (they can be unloaded using ground-level lifting rigs and unfolded using, for example, a cable mechanism), allow precise and fast completion at the building site, and allow significant reduction in the scope of work to be completed on-site, where costs and scheduling are far less manageable. Further, methods for unloading and unfolding foldable building units are described that obviate the need for one or more cranes that can be expensive and project-complicating, thereby opening up a significant percentage of building sites for placement of prefabricated foldable building units.
Abstract:
A linear actuator particularly for sliding doors and for sliding door or window closure elements in general, comprising a box-like body, to be fixed with corresponding elements of fixing between the two jambs of a door or of a window or door frame, in order to move a leaf by translational motion, fixed drive elements being accommodated within the box-like body which are adapted to move corresponding transmission elements which are associated with the leaf. The box-like body is telescopic in structure in order to be adapted in length to the width of the space of the door, or other window or door frame, with which it is intended to be used.
Abstract:
A sliding door with reversible hand configurations can include a plurality of mounting locations along a top and a bottom edge thereof. The plurality of mounting locations can be configured to allow the sliding door to selectively hang and operate according to multiple orientations in order to satisfy site-specific handedness requirements. In one implementation, the sliding door includes a door frame and mounting hardware for selectively mounting the sliding door to a roller track affixed near the upper portion of a doorway.
Abstract:
A retrofit conversion kit for converting a generally moisture intolerant door operating apparatus from overhead use to underground use and for operating a swinging door while protecting the door apparatus against moisture and dust encroachment within its underground location. The kit includes an enclosure to be mounted in a sub-floor stratum beneath a swinging door, with all of the door operating and controlling apparatus, whether electronic or mechanical, being self-contained within the enclosure. A seal arrangement provides the contamination encroachment protection while permitting access to the self-contained operating apparatus within the enclosure while the door remains in place.
Abstract:
A door closer comprises a piston cooperating with a rotating pinion. Upon rotation of the pinion in the door opening direction, the piston moves toward the second end of the housing forcing fluid from a second variable volume chamber through a passage to a first variable volume chamber and compressing a spring assembly for storing energy. The spring assembly urges the piston toward the first end of the housing for forcing fluid from the first variable volume chamber to the second variable volume chamber and rotating the pinion in the door closing direction. A controller controls the position of a valve in the passage based on the sensed angular position of a door and the position of the valve for determining the amount of hydraulic fluid flowing through the valve.
Abstract:
In a powered back door for a vehicle, which is opened and closed automatically by the drive device, a projecting end of a connection rod of a drive device is connected to an inner peripheral surface of a door frame around a door window opening of a back door, an opening is formed in a door garnish adapted to cover the inner peripheral surface of the door frame in the connection position between the door frame and the connection rod so as to open toward a vehicle compartment, a space is formed between the inner peripheral surface and the door garnish so as to be interconnected with the opening, and the projecting end of the connection rod is connected to the inner peripheral surface of the door frame in the space to conceal the connection section between the door frame and the connection rod.
Abstract:
The invention relates to a drive device, particularly for doors, garage doors, etc., comprising a guide device, particularly a rail or guide rail, extending in movement direction of the door. The invention is characterised in that the feed means comprises a first insert body which can be plugged at the ends of the guide rail into this and is provided with a connecting cable and which is held at the guide rail end and constructed in such a manner that it fulfils its function not only at one end of the guide rail, but also at the other end of the guide rail.
Abstract:
An opening, through which a connection section between a drive arm and a rod of a power back door enters and exits, is covered with cover members to improve external appearance, and interference between the connection section and the cover members is eliminated when the connection section passes through the opening to prevent abnormal noise and damage to the cover members during the passage of the connection section. A pair of cover members 6a and 6b are provided along right and left vertical edges of a vertically long opening 50 that is formed in a side edge defining a door opening 1, through which a connection section S between a drive arm 3 and a rod 4 of a power back door for automatically driving a back door 2 adapted to close and open the door opening 1 can enter and exit, such that lip-shaped end edges thereof face and contact each other. The cover members 6a and 6b are gradually expanded in width so that they have a greater width on the lower side thereof, and a contacting position is shifted downwardly and inwardly of the opening 50, thereby forming an entrance/exit opening 64 surrounded by lower edges of expanded sections of the cover members 6a and 6b, through which the connection section S enters and exits.
Abstract:
A hinge module is described. A T-shaped frame is pivotally connected with a base portion at one end such that the T-shaped frame rotates around a first axis relative to the base portion. A pair of connection members are pivotally connected with the other two opposite ends of the T-shaped frame such that the pair of connection members rotates around a second axis relative to the T-shaped frame, wherein the second axis is perpendicular to the first axis, and led through a cavity of the T-shaped frame. A U-shaped casing is manual-detachably connected with the T-shaped frame to fully cover a cavity of the T-shaped frame.
Abstract:
A hinge pin removal and attachment tool for efficiently and easily removing a hinge pin from a hinge. The hinge pin removal and attachment tool generally includes a support including a pounding portion and a handle portion, wherein the pounding portion extends from the handle portion and wherein the pounding portion includes a planar outer surface. A driving member extends from the pounding portion of the support opposite the planar surface, wherein the driving member includes a substantially uniform diameter to extend within a passageway of a hinge.
