The outer release arm 32 has a tab 33 that extends radially. The inner lever 34 of release has a tongue 35 that extends radially. Preferably, the outer tongue 33 and the inner tongue 35 they usually extend in the same direction and the tongue outer 33 is shorter than inner tongue 35.

Additionally, with reference to Figure 6, the retaining fork 44 is rotatably mounted on a pivot 18. A shock absorber 45 is positioned to absorb the impact energy between the bolt assembly 10 and the projection of the firing pin, that is, when the door closes with a knock. The spring 46 pushes the retaining fork 44 to an open state. The retaining fork 44 is generally U-shaped. retaining fork 44 cooperates with hole 48 of the housing 14 and moves between an open state, a position hooked and a subject position to receive, secure and hold on a projection of a firing pin in a manner well known in the technique.

The ratchet 50 is rotatably mounted on a pivot 22. Spring 52 pushes ratchet 50 in the path of the retaining fork 44. In a well known way in the bolt technique, ratchet 50 cooperates with fork 44 of retention in a ratchet mechanism relationship. Usually, ratchet 50 has a V-shape that has two arms. The ratchet 50 is rotatably mounted on the convex part of the V. One of the arms extends in the trajectory of displacement of the retaining fork 44. The other arm has a coupling arm 54 rotatably mounted at the end away from the convex part. The spring 52 also pushes the coupling arm 54 to extend the stop 64 in the path of displacement of the outer tongue 33 of the arm 32 of outer release and inner tongue 35 of arm 34 of inner release to selectively engage with it.

Additionally, with reference to Figure 5, the Lock cam 58 is rotatably mounted on pivot 60. The locking cam 58 has a cylindrical body 70, a tongue 72 outside and one tongue 74 inside. The outer tongue 72 It has a stop 76 that extends axially. The inner tongue 74 It has a slot 78. The locking cam 58 is rotatable and has a unlocked position, a simple locked position and a position double locked. The remote end of the coupling arm 54 it has an axially extending stop 62 that engages with friction with locking cam 58 along surface 77 Of cam.

The locking lever 66 is mounted on a pivot 60. The locking lever 66 has a shape generally in L. The far end of the base is the pivot point for the lever 66 lock. A groove 68 extends along the foot from L. The remote end 80 is connected to a locking cylinder by key Slot 68 receives a tongue 76 in a relationship slider The lock lever 66 is rotatable and has a unlocked position, a simple lock position and a double locking position, as illustrated in figure 2, which corresponds to the positions of the locking cam 58.

The body 70 has a pair of latches 71 and 73 of longitudinal extension extending from tongue 72 Exterior. The spring 38 has a grooved end 75 that engages with the body 70 in the sureties 71 and 73. The sureties 71 and 73 are positioned to correspond with the rotating position of the lock cam 58 for an unlocked position, a position of single lock and a double lock position. The body 70 will rotate between the unlocked position, the simple lock position and the Double lock position in a staggered manner.

Additionally, with reference to Figure 7, Illustrates the simple lock subset. Lock set simple has a U-shaped bracket 82 mounted on the part outside of cover plate 12 adjacent to slot 84. The inner release lever 86 is rotatably mounted on a support 82. The axis of rotation of the release lever 86 is orthogonal to the axes of rotation of pivots 18, 20 and 22. The Inner release lever 86 is L-shaped. Base 88 is extends in the housing of the bolt 10 to engage with the tab 90 of inner release arm 34. The movement rotating lever 86 inside release makes a rotating movement of the inner release arm 34 against the spring thrust 38.

The inner locking arm 92, the crank 94, the spring support 96 and the spring 98 are commonly mounted on pivot 100 for its rotation around it. Pivot 100 it is mounted and fixed on support 82. Spring 98 pushes the spring support 96 in a locking direction around the pivot 100. The support 82 has a slot 102 through which communicates the inner locking arm 92 to extend in the inside of the door lock 10.

The spring support 96 has a stop for engage with the tongue 83 of the support 82 to limit the rotation in a blocking direction. The locking arm 92 has a disc part that has a series of gear teeth 104 for engage with an actuator of a motorized locking system doors and a tab 106 that extends radially. The tongue 106 is coupled with a groove 78 of the inner tongue 74. The rotation of the locking arm 92 will cause the cam to rotate 58 lock.

With reference to figures 8 and 9, arm 92 lock has a series of circumferentially 108 ramps separated that interconnect with complementary slots 110 of the crank 94. Ramp 108 has an inclined face 112 and a 114 support face. Similarly, slot 110 has a ramp inclined formed by tongue 116 and a support face 118. The ramps 108 are sized to fit completely inside of slots 110. When ramps 108 are completely adjusted, the locking arm 92 and the crank 94 are coupled and will spin together.

The crank 94 has a stop 109 that engages with bracket 82 to limit crank travel allowing the locking arm 92 to rotate in a sense of lock to move from a simple lock position to one of double lock The inclined ramp of tongue 116 will move to along the inclined ramp of the inclined face 112, once the spring thrust 98 has been exceeded. Once the crank 94 and the locking arm 92 has traveled the length of the slope, the face of the crank 94 will slidably engage with the support surface 120 of ramp 108.

The spring support 96 has a series of axially extending auxiliary pivots 122. Crank 94 it has an auxiliary drill 124, a slot 125 and a slot 126, which they are aligned with auxiliary pivots 122. As the arm 92 lock rotates in a lock direction by exiting the crank 94 out of the cooperative movement coupled with the arm Locking 92, auxiliary drill 124, slot 125 and slot 126 of the crank 94 will be coupled with the auxiliary pivots 122. Once out of the cooperative movement, the locking arm 92 can rotate independently in a blocking direction to the double lock position. In this state, the rotation of the crank 94 in an unlocking direction will not rotate some of the locking arm 92. The thrust of the spring 98 will act against such rotation, forcing the crank 94 to rotate to the simple lock position. The thrust of the spring 98 and the interconnection of crank 94 and spring support 96 they will keep crank 94 stationary allowing arm 92 lock turn counterclockwise from the double lock position to single lock position. One time that the respective ramp surfaces 116 and 112 have been found, the locking arm 92 will fully adjust with the crank 94 reestablishing the cooperative movement.

With reference to figure 10, the lock 10 of the present invention is installed on the door face interior that faces backwards from a front door 130 and a rear door 132 of a vehicle in a conventional manner and is positioned to engage a protrusion of hammers 134 and 136, respectively. The outer release arm 32 is connected to a crank 138 outside the door for a movement Cooperative with it. Similarly, the inner lever 34 release is connected through a lever 86 to a crank 140 inside the door. The lock lever 66 of the driver's door 130 or front passenger's door is connected to an outer locking cylinder 142. The cylinder of lock can be operated with a key or a numeric keypad and to a motorized locking system 150 that has a receiver and a remote transmitter 144. Preferably, the locking cylinder 142 It has four positions: U unlocked, neutral, L simple lock and 2L double lock.

An actuator 148 is mounted to engage with the teeth 104 of the locking arm 92. In a good way known in the art, actuators 148 of each door are electronically connected to each other for operation separate or multiple from a central controller of system 150 of motorized lock

The crank 94 is connected to a crank inside door lock and to a lock switch 146 motorized interior The inner door lock crank and the internal motorized lock switch 146 have two positions: simple lock and unlocked.

In operation, bolt assembly 10 will work in a way well known in the art when it find in the state of simple or unlocked lock. In the status unlocked, cam lock 58 will be positioned for a full coupling of coupling arm 54 with at least the inner release arm 32 or inner lever 34 of release or both. The rotation of the outer release arm 32 or of the inner release lever 34, from the positions of wait for the release, will rotate the ratchet 50 to release the retaining fork 44.

The crank 94 is in complete coupling with the locking arm 92. The rotation of the crank 94 will cause the locking arm 92 and locking cam 58 rotate between the state Unlocked and simple lock status. Similarly, the external lock lever 66 is rotatable between the state unlocked and simple lock position to rotate the cam 58 lock receptively.

In the simple lock state, cam 58 of Lock rotates once. The coupling arm 54 will be placed for coupling with a maximum release mechanism, preferably only the inner release lever 34. Optionally, the inner tongue 35 of the inner lever 34 of release could be shortened so that it will not engage through the  coupling arm 54 in the simple lock state, blocking Both the interior and exterior.

In the double locked position, the operator rotates the key well in the lock cylinder to a locked position double or activate a double lock 2L button on transmitter 144 remote. The lock lever 66 of the door latch driver will cause lock cam 58 to rotate once more. In response to this, the motorized locking system 150 will activate the actuators 148 of the other doors to rotate the arm 92 of lock to cause the respective lock cam 58 to rotate to The double locked position. The coupling arm 54 will be placed outside the travel path of lever 32 outer release and inner release lever 34. In this state, a "lever" is not effective since the movement of the release connections cannot effect the release of the bolt 10 of the door. Additionally, cam rotation 58 locking will rotate the locking arm 92 relative to crank 94, decoupling both and disabling the operation of the interior door locks. The actuators 148 will lock the door locks in the state double lock As a result, the only way to unlock the door locks 10 is through the locking cylinder 142 by key or through motorized locking system 150.

The specific embodiment above is illustrative. of the practice of the present invention. However, you must it is understood that other known resources may be used or evident to those skilled in the art or described in the present document without departing from the scope of the invention such as defined in the appended claims.
