Abstract: The device performs the function of opening and/or closing lids attached to containers, and more particularly child-proof lids in at least some embodiments. The device preferably includes a base, a post, a lever, a plate to engage the lid of a container, and a mechanism that coverts movement of the lever to rotational movement of the plate against a lid. The conversion mechanism in at least some embodiments includes a spring.

Abstract: This invention relates to gravity reactive braking systems. According to the invention there is provided a brake system to control speed in a forward direction for descending inclined surfaces and a brake system for controlling rollback when ascending an inclined surface. The speed pacer braking assembly includes a downhill activator for selectively engaging a disc brake system when a predetermined inclined is reach. The anti-rollback assembly comprises a pair of graded brake cam structures operatively disposed adjacent wheels wherein the natural pull of gravity and the configuration of the cams operate to allow passage of wheels in both directions when on flat surfaces and in only a single direction when on an incline. When on an incline, gravity operates to dispose cams relative to the wheels such that rotation of wheels in one direction is hindered by a thickening of cam body caused by rotation of cam about its axis.

Abstract: The device performs the function of opening and/or closing lids attached to containers, and more particularly child-proof lids in at least some embodiments. The device preferably includes a base, a post, an arm, a mechanism that converts straight movement to rotation movement, and a plate to engage the lid of a container. The conversion mechanism in at least some embodiments includes a spring.

Abstract: The present invention is a portable securing apparatus for fastening and unfastening a lid to a container. The apparatus minimizes or prevents health risks of medical conditions associated with repetitive and cumulative motions by minimizing or preventing repetitive motions performed by an individual. The apparatus includes a base and a balancer configured to hold a rotational drive mechanism. The base provides support for the container by allowing the container to rest thereon in an upright position. The balancer is connected to the base and is configured to hold the rotational drive mechanism. The balancer provides for movement of the rotational drive mechanism to engage the container lid.
