Description

REMOTE ENTRY LOCK KIT This invention relates to lock sets that can be closed on the outside by a key and locked on the inside by turning a turn button and more particularly with said knob or lock set which can also be opened when a receiver in the lock set receives an encoding of a remote transmitter.

BACKGROUND OF THE INVENTION The rolling coding technology has been developed to the point that it is economically feasible to incorporate it into seamers such as car and home locks. With house locks, battery power is often the preferred source of energy. This imposes severe limitations since the owner of the house does not want to be replacing expensive batteries every month.

OBJECT OF THE INVENTION Accordingly, it is an object of the present invention to provide a remote entry knob lock kit which will utilize very much current in the remote input mode.

Other objects and advantages of the present invention will become apparent from the following portion of this specification and the accompanying drawings, which illustrate in accordance with the mandate of the patent statuses, a currently preferred embodiment embodying the principles of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a detailed perspective view of a portion of a lock kit made in accordance with the teachings of the present invention; Figure 2 is an axial view of a portion of the lock set shown in Figure 1, in the locked door position. Figure 3 is a view taken in 3-3 of Figure 1; Figure 4 is an axial view of the portion of the closure set shown in Figure 2. when the door has been unlocked with the use of a remote transmitter; and Figure 5 is an axial view of the portion of the lock set shown in Figure 3, when the external lock or knob has been rotated.

BRIEF DESCRIPTION OF THE PREFERRED MODE A sliding actuator 10, which is positioned within a sliding actuator housing 12 (the upper and lower edges 13 of the sliding actuator are positioned within the bent upper and lower flanges 15 of the sliding actuator housing), it has a follower surface 14 which is displaced by a cam ramp 16 in a round spindle 18. A transverse link 20, formed at one end of the round spindle, cooperates with pins 22 defined at the open end of a lock lead 24, so that when a key 26 is placed in the stopper and rotated to lock the door, the plug pins will engage the transverse link 20 and rotate the round spindle 18, thereby moving the actuator 10 by sliding to a latched door position where the concave end 28 of the sliding actuator catches the detent portion 30 of a slide 32 of interlocking (figure 2). A compression spring 34 which is positioned within a cavity 25 within the retainer portion, extends between a vertical support 27 of a spring stop member 29 which is secured to the base 42 of the lock housing 36 and the wall 31 of the front end of the retainer portion cavity, continuously drives the locking slider to this secured door position. As can be seen from Figures 1 and 3, one of the threaded posts 38 of the lock housing is integral with a bridge 40 having a top portion 41 and opposite sides 43 that is part of the base 42 of the lock housing 36. This bridge is configured to catch the detent portion 30 of the locking slider and restricts it to linear movement between the door interlock position (FIG. 2) and the released door position (FIGS. 4 and 5). When a transmitter T 44 transmits the correct coding, a receiver r 46 supplies a signal of "connection" to a solenoid 48. The normally advanced pin 50 of the solenoid which is biased towards the locking position by the compression spring 72 will retract. from its advanced position (Figure 2) to its retracted position (Figures 4 and 5) and as a consequence, the locking piece 52, which is secured to the end of the solenoid pin 50, which in the advanced position, blocks the movement of the holding slide (a portion 53 of the lock housing wall acts as a physical stop for the movement of the blocking piece 52 by means ofa latching slide) will move to a retracted position free of the latch slider. Now the outer operator (knob) 54, which rotates with the round half 56 to operate the bolt 58 to pull the bolt 60, can be rotated to release the door (the rounded surface 62 of one of the end projections 64 of the sliding actuator. engages and cam with the detent portion 30 of the detent slide rearwardly out of the way). The rounded surfaces 62 are extended by surface extenders 62E which are secured to the slide actuator. As soon as the knob or lock is released, a detent spring 66 will return the knob to its neutral position (the bent ends 68 of the spring coupling housing posts 70). The compression spring will return the locking slide to its advanced position and the solenoid, after a timed interval, will be disconnected thereby allowing the locking piece to return to its advanced locking position. The door can also be conventionally opened by rotating the key, and therefore, the spindle 18 is rounded to retract the slide actuator 10 away from the detent portion. Additional details of the conventional portion of this closing game are described in the U.S. Patent. No. 5,335,950.

CLAIMS: 1. A lock key comprising: a latch mechanism including an extendable dead bolt, a lock housing, a first spindle mounted on the lock housing for rotary movement, a slide actuator, an actuator housing of slide mounted on the first spindle to support the slide actuator for linear movement relative to the slide actuator housing, a spring element interconnecting the lock housing and the slide actuator housing to establish a first neutral orientation of the spindle , a key operated element for linearly moving the slider actuator from a retracted position to an advanced position, the slider actuator having a sample thereon, an interlocking slider that includes a detent portion spring-biased in a selected address to an advanced position where the detent portion is positioned within the slider of the slide actuator when the first spindle has the first orientation with the slide actuator in the advanced position, an element to prevent the displacement of the transverse detent portion to the selected direction, an block piece, and an element for moving the locking part from a retracted position wherein the detent portion is displaceable in the selected direction to an advanced position wherein the locking part prevents displacement of the retainer portion in the direction selected, and an element to prevent displacement of the locking piece by the locking slider in the selected direction when the locking piece is in the advanced position. 2. A lock kit according to claim 1, wherein the element for moving the locking part from a retracted position to an advanced position comprises a solenoid including a movable pin connected to the locking part. 3. A lock kit according to claim 2, wherein the element for moving the locking part from a retracted position to an advanced position further comprises a receiver for supplying the solenoid with a "connection" signal when it is received. a selected encoding, and a transmitter to transmit the selected encoding to the receiver.
