Abstract:
The invention relates to an energy guide chain system comprising an energy guide chain for guiding cables, hoses or the like between a stationary and a movable connection point, an entrainment portion to which the energy guide chain is connected by way of the movable connection point, and a guide channel which has a hollow profile with a passage extending in the longitudinal direction for the entrainment portion, wherein the energy guide chain is guided in the guide passage in the longitudinal direction thereof in the form of two runs which are guided in mutually parallel relationship and which are connected to each other by way of a deflection region, as well as a sliding door system for a vehicle having the energy guide chain system. In order to achieve easy and reliable guidance of cables, hoses or the like in at least two directions, it is proposed that the entrainment portion has a movable arm which projects from the guide channel with a fastening side for connection to an apparatus movable relative to the guide channel, wherein the spacing between the fastening side and the guide channel is variable in a travel component in transverse relationship with the longitudinal direction of the guide channel.
Abstract:
The present invention is a system for high torque operation of a movable barrier utilizing a compact hub motor device, which may be directly coupled to a movable barrier without the use of additional gearing systems. The flat geometry provides high dynamic acceleration with short electrical and mechanical time constants, and its planetary gearing system implemented within the device allows for compact, more efficient access systems. Eliminating a gear system in accordance with the present invention lowers maintenance requirements, increases efficiency, and streamlines operation of movable barriers.
Abstract:
A retrofit conversion kit for converting a 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. A seal arrangement provides this contamination encroachment protection.
Abstract:
A security gate comprises a pair of posts fixed adjacent opposing sides of a gate opening. The gate includes a pair of first gate panels pivotally mounted on the posts and second gate panels pivotally coupled to the outer ends of the first gate panels respectively so that the second gate panels meet one another in the closed position of the gate. Each first gate panel and the respective second gate panel pivotally coupled thereto are moveable together between an open position folded adjacent the respective post and a closed position spanning across the gate opening. A drive linkage is coupled between each post and the inner end of the respective first gate panel pivotally coupled thereto to drive pivotal movement of the first gate panel between the open and closed position. A guide mechanism is coupled between the fixed post and the inner end of the second gate panel for guiding pivotal movement of the second gate panel between the open and closed positions responsive to movement of the first gate panel.
Abstract:
A drive mechanism is provided for a door operator, comprising a drive member and a driven member. The drive member includes a protrusion, the edges of the protrusion forming first and second driving surfaces which define a free space of at least about 90° there between. The driven member includes a protrusion, the sides of the protrusion form a first and a second driven surface, respectively. The drive member is adapted to be operably connected to between a motor assembly for rotating the drive member and a door closer assembly rotating with the driven member. The drive member and the driven member are disposed for relative rotation in substantially the same plane such that the driven member protrusion moves in the free space defined by the driving surfaces of the drive member protrusion. Rotation of the drive member from a first angular orientation to a second angular orientation in a direction toward an adjacent driven surface causes rotation of the driven member for powered opening of the door from the closed position to the open position. The driven member protrusion moves in the free space without engaging the protrusion surfaces when the door is opened manually from the closed position and allowed to close.
Abstract:
A link structure of a power tailgate is disclosed in which the links opening and closing the tailgate move perpendicularly in relation to the rotational direction of the driving motor, thereby preventing an overload of the motor. Accordingly, a small capacity motor may be used for reducing the weight and raw material cost thereof. Further, as the orientation of the links is in the longitudinal direction of the vehicle body, a compact link construction is provided. Such the structure includes a rack gear meshing with a driving gear of the motor, and a multi-joint link connected at both ends thereof to the rack gear and tailgate, respectively. The multi-joint link is constituted by a plurality of link members relatively and pivotally connected to each other by means of pins.
Abstract:
Rain sensor arrangement for an operator for a window, said window comprising a frame, a sash pivotable with respect to said frame, and a pane mounted in said sash. The operator is adapted for pivoting said sash between a closed and an open position and vice versa, and said operator is controlled via a control circuitry responsive to input signals from at least a rain sensor. The rain sensor has at least one sensing area arranged so as to be protected against rain by said window, when the sash is in the closed position.
Abstract:
An automatic door operator for swing doors which uses a worm gear transmission to connect the motor to a belt and pulley which in turn is connected to a spur gear and drive gear. The door arm of the swing door is connected to a double-ended shaft which is part of the drive gear. A rack and pinion gear and spring are used to provide the closing force to the door arm. The motor is mounted over the spring and the belt and pulleys are located alongside the motor which results in a compact non-handed design.
Abstract:
An electric operator for a sliding door mounted for sliding movement along a track, comprising a motor having an iron cooling flywheel disposed on a drive shaft thereof, the flywheel being provided for imparting a predetermined amount of inertia for starting and stopping of the motor such that the operation of the motor is characterized by a soft start and stop. A worm gear reducer is connected to the drive shaft for effecting a predetermined reduction ratio of rotation. A limit switch is coupled to the reducer for limiting rotation of the drive shaft to a predetermined number of rotations, and apparatus is provided for coupling rotation of the drive shaft to the linear movement of the sliding door along the track.
Abstract:
In a power-assisted chain drive actuator for opening and closing gating fixtures, a drive chain has successive links formed of pairs of plates being parallel and swivel connected to each other by crosswise studs having an increased middle diameter holding the plates apart; the chain is also provided with members for limiting the relative angular displacement of adjacent links in the chain; between the middle increased diameters there engage the teeth of a drive sprocket; the limiting members prevent the chain from becoming deflected in the direction of its remote side from the drive sprocket past a position of substantially straight alignment of the links and take up the bending couples on the chain on application of a push force to a fixture leaf.
