Abstract:
A door opening apparatus adapted to couple with a door. The door opening apparatus includes a motor coupled to the door and operationally coupled to a drive wheel adapted to roll along the frame of a door.
Abstract:
This invention relates to a friction drive mechanism for a motorized sliding door. The door is suspended by a first rail and its movement guided by a third rail. A second rail is flexibly coupled to the first and biased against a motorized driving roller by a simple tensioning mechanism. The tensioning mechanism maintains the friction contact between the driving roller and the second rail. The flexible coupling joining the first and second rails compensates for any misalignment in the mounting of the componentry. The flexible mounting also allows for the door to be driven around curves.
Abstract:
An installation having a slidable door in which there is provided preferably two fixed side elements which are horizontally spaced, with the slidable door being movable between the side elements on rollers which are mounted on said side elements to grip top and bottom portions of the door. Balancing rollers on ground level also support the door.
Abstract:
A SLIDING GATE STRUCTURE SUPPORTED AT ONE END BY ROLLERS ENGAGING TRACKS ON A FENCE STRUCTURE AND AT THE OTHER END BY A DRIVE UNIT HAVING A REVERSIBLE ELECTRIC MOTOR DRIVING A GROUND ENGAGING WHEEL AND A SECOND GROOVED WHEEL RIDING ON A TRACK DISPOSED ACROSS THE OPENING IN THE FENCE STRUCTURE. THE DRIVE UNIT IS RIGIDLY ATTACHED TO THE
GATE AND SUPPORTS THE OTHER END AND PROVIDES A MOUNTING SURFACE FOR A SOLENOID ACTUATED LATCHING DEVICE WHICH ENGAGES A LATCH MEMBER ATTACHED TO A GATE POST OF THE FENCE TO HOLD THE GATE IN THE CLOSED POSITION.
Abstract:
An automated coupling mechanism for sliding doors that are movably mounted upon a storage unit. The coupling mechanism may comprise a rotating mechanism comprising a rotating member, and connecting unit. The storage unit may comprise at least one outer sliding door and at least one inner sliding door comprising an upper track, where the connecting unit connect the rotating mechanism to the outer sliding door. The rotating member and the track may be made from material of substantially high friction coefficient to enable the rotating member to move the inner sliding door along the track when rotated. The connecting unit, which are connect the rotating mechanism to the outer sliding door, may enable the outer sliding door to move in the opposite direction of the inner sliding door, whereby the inner sliding door is moved by the rotating mechanism as a physical counteraction.
Abstract:
A device for opening and closing a door is provided, with a rolling device having a shell-shaped housing assembled from two complementary housing parts and in which a driving device is arranged, which is connected via a drive shaft to a driving wheel which, in a fitted operating position of the rolling device, is in frictional contact with a rolling surface facing the driving wheel. A fixing body is arranged on a housing part, which together with an opposite fixing body on the other housing part, form a fixed bearing for the drive shaft, each fixing body further having a recess forming a bearing seat for a bearing of the drive shaft. A housing part has linear guide means for connection to corresponding linear guide means of a fastening element. The linear guide means are arranged adjacent to the bearing seat. A method for installing such a device is also provided.
Abstract:
A ceiling track system including a guiding rail, in which at least one wall element is received and an encasing element that is affixed to the guiding rail. A long leg extends in a vertical joining direction and has a latching geometry, into which a latching hook can be latched such that the encasing element is affixed to the guiding rail in a self-retaining manner. The long leg has a web with a projection. The guiding rail has a groove into which the projection engages for the purpose of self-retaining the encasing element. Adjacent to the groove the guiding rail has a screw reception into which a screw element is screwable by which a clamping action is achieved. The screw reception is at an angle with regard to the vertical joining direction.
Abstract:
An internally powered sliding panel has a power source and drive train contained internally within the stiles and rails of a frame. A driven wheel is rotatably mounted on the frame and connected to the power source via the drive train. The panel may further include a lift system including a second power source, a lift mechanism, and a lift drive which are contained internally within the stiles and rails of the frame. The power sources, drive train, lift mechanism, and lift drive may be contained completely inside the stiles and rails of the frame. The movement of the panel along a fixed path, and the raising and lowering of the panel, may be regulated by a control system. The control system includes a microcontroller and sensor used to determine the position of the panel.
