Abstract

A personal computer table keyboard hinge shelf-security system is described including fold-down shelf hinge pivot plates, a drawer-type linear motion key lock, and a sliding top mechanism, as shown in the drawings. The design allows non-sequential opening and closing as well as security for the swing-out cabinet keyboard shelf, and sliding top. It supports the keyboard shelf in its open position. The keyboard hinge consists of right-hand and left-hand sets of specially shaped plates, with one plate mounted on the cabinet wall and the other mounted on the keyboard shelf. They pivot on a common hinge pin which is welded on the keyboard shelf plate.

Personal Computer Table Keyboard Hinge Shelf-Security Structure

A personal computer table keyboard hinge shelf-security system is described including fold-down shelf hinge pivot plates, a drawer-type linear motion key lock, and a sliding top mechanism, as shown in the drawings. The design allows non- sequential opening and closing as well as security for the swing-out cabinet keyboard shelf, and sliding top. It supports the keyboard shelf in its open position. The keyboard hinge consists of right-hand and left-hand sets of specially shaped plates, with one plate mounted on the cabinet wall and the other mounted on the keyboard shelf. They pivot on a common hinge pin which is welded on the keyboard shelf plate. The lock is permanently mounted near the top edge of the swing-out cabinet such that the throat in the locked position will contact the interposer which interferes with the keyboard shelf plate in its closed position. This prevents intrusion into the swing-out unit or opening the keyboard shelf. By blocking the keyboard shelf, the sliding top is held in the closed position preventing intrusion into the cabinet via the keyboard or sliding top. The one operation of turning the key to the lock or unlock position activates or deactivates the entire security system.
