Tensioner devices for use with movable partition systems include endplates configured to be mounted on opposing sides or ends of a movable partition. At least one of the endplates includes a bracket configured for attachment to an end of a chain or a belt. The bracket is movable relative to the endplate. The endplate having the bracket also includes an adjustment mechanism located on a common side of the endplate with the bracket, and is operably coupled with the bracket. The adjustment mechanism is configured for adjusting a distance separating the bracket from the endplate. Movable partition systems include such tensioner devices. Methods of adjusting a tension in a chain or a belt of a movable partition system involve the use of such a tensioner device. Methods of installing movable partition systems within structures include the installation of such tensioner devices.

A sliding operator handle includes an actuatable brake providing at least one braking position in which the actuatable brake is configured to contact a track and restrict sliding motion of the track mount along the track and at least one sliding position in which the actuatable brake is configured to reduce contact with the track and allow sliding motion of the track mount along the track, and a handle pivotably coupled to the track mount. The handle is configured to receive a manual input force to slide the track mount in either direction along the track, and being further configured to actuate the actuatable brake in response to the manual input force. The handle includes a neutral position corresponding to the at least one braking position of the actuatable brake and actuation positions to allow sliding motion of the track mount along the track in response to manual input forces.

A vehicle door actuator assembly includes a base plate having a first portion and a second portion, a first gear disposed proximate the first portion of the base plate, a second gear disposed proximate the second portion of the base plate, a third gear connected to the base plate, and a linkage engaging the first, second, and third gears. The base plate of the vehicle door actuator assembly is rotatable between a first position and a second position. As the base plate rotates between the first and second positions, the vehicle door actuator assembly maintains an outer surface of the vehicle door substantially parallel to a longitudinal axis of the vehicle at all points along a travel path of the vehicle door.

This invention is about an improved garage door opener system, with design features for preventing garage door break-in from outside of the garage using an object such as a hanger. Typically, a person pulls down a cord connected to a release handle to release emergency release of a garage door opener, allowing the door to be manually open or closed. An unauthorized person may attempt to pull down the cord using a hanger from outside the garage or to pull or push down the release handle, to open the door from outside and gain unauthorized entrance. The improved garage door opener system provides a mechanism to reverse the pulling direction of the cord and also protects release handle from being accessed from outside the garage, for increased security.

A door opening system for a merchandise container comprising a plurality of bay doors, the door opening system comprising a wheel in frictional contact with a bay door of the plurality of bay doors; and a motor connected in driving arrangement with the wheel. The motor drives the wheel to rotate and thereby to control a movement of the bay door of the plurality of bay doors between a closed position and an open position.

A vertical pivoting gate operator for positioning a gate between an open position and a closed position is provided. The gate operator includes a motor drive assembly including a motor and a linkage assembly mechanically connecting a motor output to the gate such that in response to actuation of the motor, the linkage assembly transmits an opening force to positioning the gate toward the open position, and a closing force, for positioning the gate toward the closed position. A counterbalance assembly including a biasing member is operable to release stored energy against an input link to rotate a gate arm shaft so as to urge the gate toward the open position and to increase stored energy in response to rotation of the gate traveling toward the closed position to act against the gate as it approaches the closed position.

A hatch actuating device can include a housing; a sliding portion received within the housing; a gear assembly at least partially received within the housing and movably coupled to the sliding portion; and a flexible drive element coupled to the gear assembly; wherein the gear assembly is configured to open a hatch lid of a hatch through rotation of a portion of the gear assembly by pulling of the drive element.

A housing for mounting a motorized actuator on or in a fixed portion of a window that allows the actuator to be adjusted in the housing to facilitate alignment of a linkage on the actuator with a linkage on the moveable portion of a window.

In accordance with one aspect of the present disclosure, a movable barrier operator including a body, a motor supported by the body, and a rotatable drive supported by the body and configured to be connected to an elongated driven member. The movable barrier operator further includes a shaft supported by the body and a compound gear mounted on the shaft. The compound gear includes a first gear operably coupled to a drive shaft of the motor and a second gear operably coupled to the rotatable drive. The first and second gears connected such that turning of the first gear causes turning of the second gear.

A door operating apparatus for use with a door pivotably mounted to a door frame permits the door to swing in one of a manual operation and an automatic operation. The apparatus includes a housing, a first rotatable sprocket disposed in the housing and coupled to the door, a second rotatable sprocket disposed in the housing and connected to the first rotatable sprocket by a roller chain, the second sprocket having a top face with a protrusion, a drive assembly disposed in the housing and having a motor operably connected to a drive arm. A force applied to the door permits the first and second sprockets to rotate simultaneously to enable the door to swing open. Activation of the motor allows the drive arm to contact the protrusion and drive the second sprocket, thereby rotating the first and second sprockets simultaneously to enable the door to swing open.
