摘要:
A push chain is used to drive a piston into a canister of extrudable material. The push chain is stored in an elongated chain magazine, withdrawn from the magazine and into the canister by actuation of a trigger connected to a sprocket for the chain. The push chain exerts a compressive force on a piston rod connected to a piston at a point offset from the center line of the piston, causing the piston to rotate to lock the push chain. The amount of material remaining in a tube of extrudable material is enunciated by way of a contents indicator driven by the push chain.
摘要:
A piston and piston rod for a rodless dispenser for extrudable material are configured such that compressive force exerted on the piston from a push chain causes a reactive torque to be created that locks the links of the chain together. The push rod is located away from the piston's geometric center.

A quick-release ratcheting mechanism for a weight lifting bar system. The present invention utilizes a ratcheting device in conjunction with ratchet teeth which are located on the inside surface of an aperture of individual weight components. As such, when the individual weight components are placed onto the present invention, the present invention ratcheting system engages the weight component teeth, subsequently creating a fixed and secure engagement. If the user desires to remove the individual weight component, a quick-release handle disengages the ratchet mechanism and allows free removal of an individual weight component. As a further feature the present invention, the preferred embodiment incorporates a unique passive interlocking means between each adjacently placed individual weight component and a unique geometric configuration which enhances the stability of the present invention.

A mounting bracket mountable to the underside of the cabinet prior to the range hood and configured to engage and support the range hood as the range hood is secured to the cabinet. The mounting bracket having a support feature engagable to the range hood to hold the range hood proximate the cabinet while fasteners are sunk to secure the range hood to the cabinet. The mounting brackets are pre-positioned on the cabinet such that range hood is aligned with the cabinet when the range hood is supported by the support feature. The smaller mounting brackets can be more easily mounted in the proper position on the cabinet then the larger range hood speeding the installation process and reducing errors.

A ring mechanism includes a chassis and a hinge blade coupled to the chassis. An actuator coupled to the chassis moves the hinge blade between a first position and a second position. A ring half coupled to the hinge blade is positioned in a closed position when the hinge blade is in the first position, and an open position when the hinge blade is in the second position. A dampening member is positioned at least partially between the inner surface of the chassis and the actuator to prevent at least a portion of the actuator from directly engaging the inner surface of the chassis during movement of the actuator between the first and second positions. A locked state indicator indicates to the user whether the ring mechanism is in a locked position or an unlocked position. The dampening member can function as the lock state indicator and vice versa.
