摘要： A first belt tensioner includes an arm, spring case, coil spring, and arm plate. The arm is adapted to support an idler pulley and has a hook portion. The spring case is disposed in the arm and has a first spring seat. The spring is disposed in the spring case. The arm plate has a second spring seat. The spring is longitudinally compressed between the arm plate and the spring case. The spring is in torsion with the end portions of the spring seated against a corresponding spring seat and with the arm plate rotationally positioned under the hook portion. A method for assembling the first belt tensioner includes using the arm plate to longitudinally compress the spring and rotating the arm plate. A second belt tensioner includes an arm, spring case, coil spring, arm plate, and pivot bushing.

摘要： A belt tensioner is provided for mounting on a mounting surface of a structure. The tensioner comprises a body, which defines a cavity, and a drain hole that is in communication with the cavity. The drain hole is located on the body so as to be facing the mounting surface of the structure when the tensioner is mounted on the structure. In this manner it is more difficult for contaminants to enter the body than to exit the body.

摘要： A new tensioner is disclosed that achieves asymmetric damping in part by using a moveable ramp plate. The moveable ramp plate is in frictional contact with the arm provides asymmetric frictional damping for the tensioner arm when the arm experiences wind-up and begins to move away from the belt. The ramp plate is rotatably associated with the movement of the tensioner arm through a spring. The tensioner arm may pivot in two directions. As the tensioner arm pivots in a direction toward the belt the ramp plate is urged such that friction between the ramp plate and tensioner are minimized. When the tensioner arm pivots in the opposite direction, as potentially typified by wind-up, the ramp plate is urged such that friction between the ramp plate and tensioner is increased thereby minimizing wind-up of the tensioner arm.

摘要： A tensioner for tensioning a belt includes a support housing at least in part defining a spring cavity. A damping member having a first friction bearing surface is at least partially disposed in the spring cavity. An arm pivotally attached to the support housing has a second friction bearing surface. A spring is located in the spring cavity and operatively connected to the arm and damping member to pivot the damping member about a pivot location such that the first friction bearing surface of the damping member is biased against the second friction bearing surface of the arm to dampen relative movement between the arm and the support housing.

摘要： A belt tensioner includes a support housing at least in part defining a spring cavity and an arm pivotally attached to the support housing. A spring is located in the spring cavity and is operatively connected to the arm and the support housing to bias the arm about a pivot axis toward an unloaded position relative to the support housing. A damping member includes a hub and deflectable, force-applying elements that are connected to and spaced apart about a periphery of the hub. The force-applying elements are biased toward a contact surface of the arm to apply a frictional force between the contact surface and the force-applying elements to impede rotation of the arm relative to the support housing.

摘要： A playground security system comprises a power supply and a monitoring station. The monitoring station comprises a camera, a light and/or an audio deterrent device which are electrically connected to the power supply. The monitoring station can be contained in a post; and the post is part of a playground structure or can be a stand alone post. The audio deterrent device emits signals in a frequency range that is bothersome to humans between the ages of about 13 to about 25 years. The audio deterrent device and light are activated by a motion sensor. Further, the system includes a dusk-to-dawn sensor which also controls the audio deterrent device and the light. The camera can be in an “always-on” mode and can be adapted to transmit signals containing visual or audio-visual information. The camera signals can be stored and viewed remotely from the playground.
