Double-lock friction fastener system

A hospital patient restraining device having an elongated flexible restraining strap including means at one end thereof for releasable attachment to a fixture remote from the patient and having a friction loop fastener system affixed to an opposite end thereof for placement around a bodily limb of a patient, the friction loop fastener system comprising:

• an elongated flexible first strap and a separate elongated flexible second strap, both affixed to the restraining strap and extending freely and independently adjacent to one another in the same general direction away from the restraining strap,
• the first strap having an inner face and an outer face adjacent a free end thereof,
• the second strap having an outer face adjacent a free end thereof,
• an elongated first friction fastener affixed to the inner face of the first strap, an elongated second friction fastener affixed to the outer face of the first strap, and an elongated third friction fastener affixed to the outer face of the second strap,
• an elongated flexible locking strap affixed to and extending freely and independently adjacent to the outer face of the second strap and having an inner face for extending adjacent to the third friction fastener on the outer face of the second strap, and
• an elongated fourth fiction fastener affixed to the inner face of the locking strap,
• the first and second flexible straps each having a sufficient length so that the first and second straps are formed as a loop at one end of the restraining strap to wrap around the bodily limb of the patient, with the inner face of the first strap and the outer face of the second strap overlying one another along substantial lengths thereof, with the first and third friction fasteners being frictionally secured to each other for forming an infinitely adjustable and releasable friction loop fastener round the limb of the patient, the second friction fastener facing away from the friction loop fastener, the inner face of the locking strap having a sufficient length for overlying the outer face of the fastened first strap with the second and fourth friction fasteners being frictionally secured to each other so the locking strap fastened to the outer face of the first strap forms a releasable, frictional double-lock for the friction loop fastener.
