Title: Lightweight vertical lift device for windy conditions
Inventor: SMITH DAVE W
IPC: B64F1/315
Filed: 1996-08-30
Granted: 1999-05-11
Abstract: The present invention is an improved wheeled, light-weight lift which meets standards for airline ground support vertical lift devices, specifically being capable of use on airport tarmacs in winds up to 90 mph. On and off-loading ramps are provided which are rotatable between an upright stored position and a horizontal working position. The ramps comprise a bridge structure supporting a plurality of louvred deck plates. Each louvre is linked to the others so as to remain oriented horizontal regardless of the ramps position for minimizing their aerodynamic profile and overturning moment. Outriggers are extendible from the frame so as to increase its base dimensions and thus the moment needed to overturn the lift. The outriggers retract into the frame to minimize storage. The outriggers are horizontally movable along their longitudinal axis to minimize the deployment space required. Lastly, it is preferable to increase the effective weight of the lift by providing wind deflection surfaces or airfoils to create a downward reactive force and thereby increase lift's resistance to overturning.

Title: Tamper-proof device for lockingly attaching a piece of equipment to a support base
Inventor: ARCHAMBAULT BRUNO
IPC: E05B73/00
Filed: 1997-02-12
Granted: 1999-11-23
Abstract: A tamper-proof device is provided for lockingly attaching a piece of equipment such as a TV set or a microwave oven to a support base. It has a pair of rigid plates that are respectively connected to the piece of equipmentand the support base. One of the plates is surrounded by a flange which defines a closed area in which wedges are located to hook both plates together. The two plates are rigidly connected to each other by a screwable bolt that can be reached with a screw driver through a coaxial opening provided in the flange. A sleeve extends in between the head of the bolt and the opening. This sleeve can be closed by key-operated lock in order to prevent access to the bolt. The lock is free to rotate within the sleeve even when its latch is locked in outward position. Such prevents a theft from breaking the latch by forcing the lock into rotation in a cantilever fashion. A resilient plate is mounted within the closed area in such a manner as to extend radially close to the sleeve in order to contact the latch when the latch projects radially outwardly of the sleeve. This plate is resilient enough to let the latch flip over it if too much rotational force is applied to the lock within the sleeve.
