A security device for hindering the unauthorized opening of safes includes first and second, retractably cooperable longitudinal members. First and second lateral members are provided at respective outer ends of the longitudinal members. A locking mechanism locks the first longitudinal member to the second longitudinal member. A tension spring retractably biases the second longitudinal member into the first longitudinal member. The locking mechanism can include a clamping member swivellably attached to the first longitudinal member and containing a pawl member, while the second longitudinal member includes a sawtoothed element. The clamping member can then be swiveled, so as to push the second longitudinal member further into the first longitudinal member. A vernier arrangement may be included to further tighten the lateral members against the walls of the safe. The device provides, firstly, a visible deterrent and, secondly, a physical barrier to would-be intruders.

An auto steering wheel safety lock includes an elongate rod, a lock core and a telescopic rod. The elongate rod has a through hole. The lock core installed in a vertical portion of an L-shaped core sleeve has a key hole. The vertical portion of the sleeve possesses a locking bar extended outward from its right side to form a wide locking groove to fit with diverse steering wheels. The core sleeve further has a horizontal portion combined with the elongate rod in a line and having a through hole communicating with the through hole of the elongate rod. The telescopic rod is movably extended in the through holes of the both, formed with plural ACME threads for engaging with the lock core to keep the telescopic rod positioned immovable in place, and having a hook located at its rear end. The hook and the vertical portion of the core sleeve are positioned at the underside of the lock. As the auto steering wheel safety lock is locked on a steering wheel, the key hole is hidden in a little space under the steering wheel, making a burglar unable to conveniently damage or even break the lock core.
摘要:
A security bar for quickly barricading a doorknob-operated, outward-opening door from inside a room, especially useful for fire safety doors used in schools and similar institutions. The bar spans the doorway from the knob to at least one side of the doorframe, with the ends of the bar overlying, and preferably directly engaging, the sides of the doorframe in a non-rotating fashion. The bar has a doorknob-engaging platform that engages the inner doorknob. A clamping member carried by the doorknob-engaging platform normally rests in a storage position out of the way of the doorknob while the bar is being applied to the door, but is quickly activated to clamp the doorknob to the platform. A lock is optionally engaged to lock the clamping member in place and prevent attempts to lift the bar out of engagement with the doorknob. Attempts to force the door open from the outside simply force the bar more tightly against the doorframe.
