  • Patent number: 6173593
    Abstract: An improved locking mechanism and method for securing drawers and cabinet doors is disclosed which allows the drawers and cabinet doors to be only partially opened until the locking mechanism is unlocked. When the drawer or cabinet door is closed, the hidden locking mechanism of the present invention is entirely concealed from view behind the drawer or cabinet door. The locking mechanism of the present invention allows the drawer or cabinet door to be opened sufficiently to expose the locking mechanism, but effectively prevents the drawer or cabinet door from being more than slightly opened until the locking mechanism is unlocked. When the locking mechanism is unlocked, the drawer or cabinet door may then be fully opened.

  • Patent number: 5611286
    Abstract: An extendible bunk stake mounted on a logging vehicle has an extension member that can be raised and lowered within a support member by an operator. A remotely actuatable motor, such as a source of working fluid and an expansible working chamber can be enabled by an operator to raise and lower the extension member from a safe distance away from a log loading area of the vehicle. Particularly, during periods of inclement weather, a vehicle operator can safely raise and lower the extension member without having to climb on top of the vehicle, greatly reducing any risk of related injury.
