BACKGROUND OF THE RELEVANT PRIOR ART

Field of the Invention: Technical Field

The Skiles Locking System, S. L. S. incorporates the existing Kwikset tubular locking cylinder in its operation. The S. L. S. Locking System utilizes multiple internal spring loaded sliding bolts and also multiple internal spring loaded floating locks within the spring loaded sliding bolts. The S. L. S. rotating discs which are attached to the Kwikset tubular locking cylinder operate independently of each other yet, are located on the same Kwikset tubular locking cylinder.

BACKGROUND ART

The Skiles Locking System, S. L. S. incorporates the existing Kwikset tubular locking cylinder in its operation. The S. L. S. Locking System utilizes multiple internal spring loaded sliding bolts and also multiple internal spring loaded floating locks within the spring loaded sliding bolts, unlike the Kwikset tubular system.

The door (Fig. E) is easily closed and locked just by pushing the door on its hinges (Fig. E) into its frame, and activating the singular door lock mechanism from either “inside or outside” of the dwelling unlike Saunders, which can only be manually activated and locked once inside. In the S. L. S. Locking System, rotating the doorknob (Fig. A) is not necessary to activate the S. L. S. Locking System as is required in the “Saunders System.” This unique feature of the S. L. S. Locking System (Fig. A) enables multiple internal spring loaded bolts (Figs. B & C) within the door (Figs. C & E) to be activated immediately and simultaneously after closure of the door (Fig. E) creating a safe, secure and defended position for the occupants without having to activate “additional locks,” dead bolts or keyed mechanisms in the door, saving precious seconds and possibly lives in the process.

BRIEF SUMMARY OF THE INVENTION

A mechanized system of multiple internal spring loaded sliding bolts and internal spring loaded floating lock mechanisms located inside of the door. The S. L. S. Skiles Locking System protects the occupants and their property from unwanted intruders, harm and theft. These internal spring loaded sliding bolts and their internally located spring loaded floating locks are interconnected with and to a centrally positioned door knob mechanism and to the S. L. S. rotating discs which allow activation of the locking system mechanism either “inside or outside” of the dwelling into the locked or unlocked position. The S. L. S. Skiles Locking System is also activated inside or outside of the dwelling with either a key, “button” (inside) or “electronic keyless entry device,” allowing the door to be unlocked and opened. This can be done from either side of the door, (inside or outside) unlike the Saunders locking system, which allows operation only from the inside. The same simultaneous movement and action in the S. L. S. Locking System is accomplished (Fig. B) with all multiple internal spring loaded lock mechanisms.

When the doorknob is compromised (Fig. I) the S. L. S. mechanisms (Fig. J) will remain locked in place (Fig. K). The wire connectors between the internal spring loaded bolt locks and the S. L. S. door knob mechanism (Fig. I) will be broken by force. The steel connecting wires once separated from the S. L. S. doorknob mechanism and their respective internal spring loaded bolt locks cannot be reattached. The locked position of the S. L. S. mechanism (Fig. K) cannot be unlocked manually because the connecting wires (Fig. I) are unreachable by the intruder.

When the doorknob is compromised by force, (Fig. I) adverse pressure is applied to the mechanism and its connections. An incorporated “weak-link” (Fig. I) is built into the connecting wires. (Fig. J) This part (Fig. J) is made from a softer and weaker metal (brass) as compared to the (steel) connecting wires (Fig. J) which “connect” the S. L. S. internal spring loaded bolt locks to the S. L. S. doorknob mechanism. (Fig. I) When compromising force is applied to the S. L. S. doorknob mechanism, (Fig. I) the connecting wires (Fig. I) will separate at the “weak-link” (Fig. I) and disconnect the attachment to the S. L. S. internal spring loaded bolt locks (Fig. J) and the S. L. S. doorknob mechanism (Fig. I). When this separation occurs, the internal spring loaded bolt locks (Fig. K) will remain in the “locked” position (Fig. K) by way of the internal springs within the bolt mechanism, (Fig. K) providing continued force upon their respective bolt locks within the mechanism. (Fig. K) This “locked” position of the door within its frame (Fig. K) cannot be reversed manually or otherwise because of the disconnection of the two mechanisms (Fig. I) within the system and door.

DETAILED DESCRIPTION OF THE INVENTION

1. Internal spring loaded bolt locks are simultaneously activated by a key, button or remote electronic device.

2. When the doorknob mechanism is compromised, (Fig. I) the internal locking mechanisms will remained locked in place.

3. The S. L. S. locking mechanism with the internal spring loaded bolt locks are completely contained within a brass cylinder within the door.
