A keypad lockset adapted for deadbolt as well as lever locks, and having as a first embodiment an exterior gear train, an interior gear train, and an electronically controlled clutch for coupling the gear trains when engaged and for uncoupling the gear trains when the clutch is disengaged, so that when the clutch is engaged rotation of an external thumb turn will permit the door latch to be withdrawn and thus to permit opening of the door, and a mechanical override mechanism that can be operated in case of electrical failure, and in which clutch mechanism and the override mechanism both operate through the single, standard 2⅛ inch door preparation hole, or alternatively as a second embodiment, a keypad lockset in which two four-bar mechanical linkages are used in place of gears as means to actuate the clutch, and alternatively to provide for a pass-through override function.

The present invention discloses a gate control device which controls the passage (e.g., entry, exit, etc.) through a passageway of both authorized persons and unauthorized companions of authorized persons into a protected room. The device may be configured such that the unauthorized companions may be permitted or denied passage if the unauthorized companions are with an authorized person. For example, the device may be configured to allow an entire group of persons to enter a room if only one authorized person is present. In another example, the device may deny passage to the entire group if it contains even one unauthorized person.

A combination lock container (10), suitable for accepting a wine bottle, consisting of an upper housing (12), a lower housing (50), a plurality of tumblers (18A-18E), and externally applied indicia (24). Cylindrical walls, or skirt portions, of each housing nest and engage into one another. Each housing has a key-like feature, consisting of a linear array of tabs with gap spacing between, that projects radially from the outer cylindrical wall surface. The upper housing has a longitudinal slot opening in the cylindrical wall, adjacent to its set of tabs, which can accept the tabs of the lower housing. When the housings are fully assembled, matching tab and gap features on each housing are adjacent and in lateral alignment with respect to each other. A plurality of tumblers, each with an internal annularly formed locking rib, are placed concentrically around the housings. The locking rib wall has a section removed that creates a keyway opening, the width of which is slightly greater than that of the aligned tabs. Located on the tumbler's outer circumference, and directly above the keyway, is a score mark or keyway indicator. Applying a personalized code word to the locking mechanism requires no disassembly. By using the keyway indicator features, indicia may be applied externally such that designated letters of a code word can be applied and aligned directly over the tumbler keyway. Once applied, the indicia conceal the location of the score marks. Locking ribs rotate through and intersect the laterally aligned gaps between the housing tabs, thus axially locking the housings together. When the proper code word is positioned underneath a marker, all keyways fall into alignment with the housing tabs. In this unlocked condition, the housings may be separated and the bottle of wine removed. A slot opening in the upper housing additionally allows the container to be used as a coin bank.
