Security device

A hotel safe security device for hindering the unauthorized opening of safes, the device comprising:

• a first longitudinal member and a second longitudinal member, the second longitudinal member being retractably co-operable with the first longitudinal member;
• first and second lateral members at respective outer ends of the first and second longitudinal members, the first and second lateral members being for clamping against side-portions of the safe;
• a resilient member attached at one end to the first longitudinal member and at its other end to the second longitudinal member, the resilient member being such as to bias the second longitudinal member into retraction with respect to the first longitudinal member, and
• a locking mechanism for locking the first longitudinal member to the second longitudinal member in a clamped state of the device against the safe, the locking mechanism including—
• a sawtooth element as part of the second longitudinal member,
• a rigid pawl member having a first end, which is pivotably attached to the first longitudinal member and a second end, which is engageable with a tooth of the sawtooth element, and
• a swivellable clamping member, which is swivellably attached to the first longitudinal member, the swivellable clamping member being selectively swivellable to a first position, which is a clamping-enhancing position, and to a second position, which is a non-clamping-enhancing position, the first end of the rigid pawl member being swivellably attached to the swivellable clamping member and biasing means being provided to bias the second end of the rigid pawl member toward the sawtooth element, the locking mechanism being such that, when the safe security device is in place against a safe and the swivellable clamping member is swiveled from its second position to its first position, the second end of the rigid pawl member, by engagement with a tooth of the sawtooth element, moves the second longitudinal member into further retraction with respect to the first longitudinal member, thereby tightly clamping the lateral members to the sides of the safe.
