Abstract: A wall-mounted shelving system provides for easy installation and adjustment in any number of configurations. The system includes at least one pair of vertical standards adapted to be mounted on a wall or similar supporting surface. Each standard is generally U-shaped with a backwall member adapted to be placed flush against a wall and two opposed arms extending outwardly from the backwall member. The backwall member is secured to the wall by rivets or any other suitable fastener. A ceiling mounting plate provides additional support for the standard. A plurality of keyhole slots are spaced along the pair of standard arms to receive shelf support brackets at any number of desired locations along the standard. The brackets are provided with shoulder rivets for removable engagement with the keyhole slots. The shelves are designed to snap fit over the front and back portions of the brackets to provide a secure engagement against accidental dislodgement.

Abstract: A hand development system to increase the strength and flexibility of the hands, fingers and forearms of a user. It includes a body adapted to be gripped by the hand of the user and a plurality of individually movable members operatively associated with the body. Each of the individually movable members, which may be in the form of keys, is adapted to be moved by one of the fingers of the user against resistance to movement provided by a component such as a spring. It includes a set of replaceable cartridges disposed in an interior compartment of the body for this purpose. With this construction, the cartridges each include at least one spring having a selected resistance to movement and each of the cartridges is positioned to resist movement of one of the keys.
