Abstract

To prevent intruders from forcing a deadbolt out of a locking position, the deadbolt has a sleeve defining inside and outside slots. Each of these slots has a horizontal section and a locked position vertical section. Cross members extend through the slots and are placed in the locked position vertical sections when the deadbolt is in the locked position. This prevents the deadbolt from being forcibly unlocked.

Claims

1. A deadbolt lock for a door, comprising:

a sleeve defining an inside slot within the lock and an outside slot exposed to the outside of the lock, each slot having a locked position vertical section and a horizontal section;

a deadbolt slidably mounted within the sleeve;

an outside cross member portion attached to the deadbolt and extending through the outside slot;

an inside cross member portion attached to the deadbolt and extending through the inside slot, the deadbolt being in a door locking position when each cross member is moved from the horizontal section to the locked position vertical section of the respective slot, the vertical sections thereby preventing the deadbolt from being moved into an unlocked position;

an activator mounted within the lock, the activator being positioned to engage the inside cross member portion so that moving the activator forces each cross member portion from the locked position vertical section into the horizontal section whereby the deadbolt can be moved to the unlocked position;

wherein each slot further comprises an unlocked position vertical section, the horizontal section of each slot separating the unlocked position and locked position vertical sections, the deadbolt being in the unlocked position when the cross members are placed in the unlocked position vertical sections; and

a second activator, the second activator being positioned so that rotating the second activator forces the cross members from the unlocked position vertical section into the horizontal section.

2. The deadbolt lock of claim 1, wherein the second activator comprises a lever.

3. A deadbolt lock for a door, comprising:

a sleeve defining an inside slot within the lock and an outside slot exposed to the outside of the lock, each slot having a locked position vertical section and a horizontal section;

a deadbolt slidably mounted within the sleeve;

an outside cross member portion attached to the deadbolt and extending through the outside slot;

an inside cross member portion attached to the deadbolt and extending through the inside slot, the deadbolt being in a door locking position when each cross member is moved from the horizontal section to the locked position vertical section of the respective slot, the vertical sections thereby preventing the deadbolt from being moved into an unlocked position;

an activator mounted within the lock, the activator being positioned to engage the inside cross member portion so that moving the activator forces each cross member portion from the locked position vertical section into the horizontal section whereby the deadbolt can be moved to the unlocked position;

wherein each slot further comprises an unlocked position vertical section, the horizontal section of each slot separating the unlocked position and the locked position vertical sections, the deadbolt being in the unlocked position when the cross members are placed in the unlocked position vertical sections; and

a key acceptor coupled to the second activator so that rotating the key acceptor rotates the second activator.

4. The deadbolt lock of claim 3, further comprising the second activator further comprising an arm rotatably coupled to the key acceptor, the arm engaging the inside cross member portion so that the rotation of the arm moves the deadbolt into the unlocked position.

5. A deadbolt lock for a door, comprising:

a sleeve defining a wall and a slot, the slot having a locked position vertical section and a horizontal section;

a deadbolt slidably mounted within the sleeve;

a cross member attached to the deadbolt and extending through the slot, the deadbolt being moved into a locked position when the cross member is moved from the horizontal section to the locked position vertical section of the slot whereby the locked position vertical section prevents the deadbolt from being forced into an unlocked position;

a resilient component mounted between the wall and the deadbolt, wherein the expansion of the resilient component propels the deadbolt into the locked position;

the cross member including an outside cross member portion extending outside of the lock;

a weight disposed on the cross member outside portion;

a key acceptor mounted on the lock;

the slot defining an unlocked position vertical section; and

the rotatable component further comprising a rotatable arm wherein the arm engages the cross member in the horizontal section and the rotation of the arm places the cross member in the unlocked position vertical section.

6. A deadbolt lock for a door, comprising:

a sleeve defining an inside slot within the lock and an outside slot exposed to the outside of the lock, each slot having a locked position vertical groove and a horizontal passage;

a deadbolt slidably mounted within the sleeve;

an outside cross member portion attached to the deadbolt and extending through the outside slot;

an inside cross member portion attached to the deadbolt and extending through the inside slot, the deadbolt being in a door locking position when each cross member is moved from the horizontal passage to the locked position vertical groove of the respective slot, the vertical groove thereby preventing the deadbolt from being forced into an unlocked position;

an activator mounted within the lock, the activator being positioned to engage the inside cross member portion so that moving the activator forces each cross member portion from the locked position vertical groove into the horizontal passage whereby the deadbolt can be moved to the unlocked position;

wherein each slot further comprises an unlocked position vertical groove, the horizontal passage of each slot separating the unlocked position and locked position vertical grooves, the deadbolt being in the unlocked position when the cross members are placed in the unlocked position vertical sections; and

a second activator, the second activator being positioned so that moving the activator forces the cross members from the unlocked position vertical grooves into the horizontal passage.
