Description

AUXILIARY LOCK FOR PREVENTING MOVEMENT OF LOCKING ELEMENT
FIELD OF THE INVENTION
The present invention relates generally to door locks, and particularly to an auxiliary lock for preventing movement of a locking element mounted in a door, even though the locking element is actuated by a different locking mechanism.
BACKGROUND OF THE INVENTION
Lock assemblies for use with doors or windows, hinged or sliding, are well known in the art. Such lock assemblies typically include one or more movable locking elements, such as a vertical bar mounted along a free side edge of the door or window or a horizontal latch bolt, which is moved in and out of a locked position by a lock, such as a cylinder lock or mortise lock. A handle or lever is normally included as part of the lock assembly and is adapted for manual rotation to retract the locking element and thereby permit the door or window to be opened.
However, there are situations where an owner of the door or window would like to prevent movement of the locking element, so as to prevent locking or unlocking of the door or window by another person, even if that other person has an authorized key to the cylinder lock or mortise lock.
SUMMARY OF THE INVENTION
The present invention seeks to provide an auxiliary lock for preventing movement of a locking element mounted in a door, even though that locking element is actuated by a different locking mechanism (called the “locking-element locking mechanism”), as described more in detail hereinbelow. For example, if the locking-element locking mechanism is in a locked position (meaning the door is locked), the auxiliary lock can prevent movement of the locking element, so that even if an authorized key is used to try to unlock the locking-element locking mechanism (to try to open the door), the auxiliary lock will prevent movement of the locking element, and thus prevent the door from being opened. This can be useful in a situation, for example, if a maid has an authorized key but the house owner is on vacation and does not want the maid to enter the house with her key. The house owner simply locks the auxiliary lock and the maid cannot gain entry since she does not have the key to the auxiliary lock.
In another example, if the locking-element locking mechanism is in an unlocked position (meaning the door is not locked), the auxiliary lock can prevent movement of the locking element, so that even if an authorized key is used to try to lock the lockingelement locking mechanism (to try to lock the door), the auxiliary lock will prevent movement of the locking element, and thus prevent the door from being locked. This can be useful in a situation, for example, if a child has an authorized key and wishes to lock himself/herself in a room. The house owner simply locks the auxiliary lock and the child cannot lock the door since he/she does not have the key to the auxiliary lock.
It is noted that the term “door” as used throughout the specification and claims encompasses any kind of door, window, gate or panel, for example.
There is thus provided in accordance with an embodiment of the present invention a method for door security including providing an auxiliary lock which is movable to a locked orientation that prevents movement of a locking element mounted in a door, wherein the locking element is actuated by a locking-element locking mechanism which is different than the auxiliary lock, wherein if the auxiliary lock is in the locked orientation, then even if an authorized key is used to try to unlock the locking- element locking mechanism in order to try to open the door, the auxiliary lock prevents movement of the locking element and prevents the door from being opened, and wherein if the auxiliary lock is in the locked orientation, then even if the authorized key is used to try to lock the locking-element locking mechanism in order to try to lock the door, the auxiliary lock prevents movement of the locking element and prevents the door from being locked.
The auxiliary lock may include a locking member that abuts against a surface of a stopper element mounted on the locking element of the door, when the auxiliary lock is in the locked orientation. The locking member may abut against a first surface of the stopper element when the authorized key is used to try to lock the locking- element locking mechanism, and may abut against a second surface of the stopper element when the authorized key is used to try to unlock the locking-element locking mechanism.
In accordance with an embodiment of the present invention the auxiliary lock includes a set of locking members of different lengths, and each of the locking members abuts against a surface of a stopper element mounted on the locking element of the door, when the auxiliary lock is in the locked orientation. The method further includes choosing one of the locking members of the set and installing that locking member in the auxiliary lock.
In accordance with an embodiment of the present invention the auxiliary lock includes one or more locking bolts, and moving the auxiliary lock to the locked orientation causes the one or more locking bolts to move out of a housing of the auxiliary lock. In accordance with an embodiment of the present invention the auxiliary lock includes a locking member that engages an aperture of the locking element of the door, when the auxiliary lock is in the locked orientation. The auxiliary lock may include a set of locking members of different lengths, and each of the locking members engages an aperture of the locking element of the door, when the auxiliary lock is in the locked orientation. The method further includes choosing one of the locking members of the set and installing that locking member in the auxiliary lock.
The method may include using a jig to mount the stopper element on the locking element of the door.

Reference is now made to Figs. 5A and 5B, which illustrate an auxiliary lock 10, constructed and operative in accordance with an embodiment of the present invention.
The auxiliary lock 10 may include a cylinder lock 12 or any other kind of lock, mounted in a mortise lock housing 14. The cylinder lock 12 actuates one or more locking bolts 16, such as dead bolts, that can pass through apertures in a face plate 18, as is known in the art.
The actuation mechanism of auxiliary lock 10 may include a cam 20 that is turned by cylinder lock 12; cam 20 may be arranged to abut against one of teeth 22 of a plate 24 coupled to locking bolts 16. Plate 24 may be formed with an elongate channel 26. A pin 28 of a link member 30 can slide in channel 26. Link member 30 may be pivotally coupled to a locking member 32 at a pivot 34.
In Fig. 5A, auxiliary lock 10 is in an unlocked position; locking member 32 and locking bolts 16 do not protrude out of housing 14.
In Fig. 5B, auxiliary lock 10 is in a locked position; locking member 32 and locking bolts 16 protrude out of housing 14.
Reference is now made to Fig. 1, which illustrates auxiliary lock 10 mounted in a door 36 and in an unlocked position. A locking element 38 is mounted in door 36, such as a vertical locking bolt, but the invention is applicable for locking elements that are horizontal or at any angle. Locking element 38 is actuated by a locking- element locking mechanism 40, such as a cylinder lock, which is different than the auxiliary lock 10. The locking- element locking mechanism 40 may include a handle 42, latch 44 and locking bolts 46, as is known in the art.
Reference is now made to Fig. 4. In one embodiment, locking member 32 may engage an aperture 48, which may be one of several apertures 48, formed in the locking element 38, when the auxiliary lock 10 is in the locked orientation. The locking element 38 may be previously formed with the apertures 48 or the installer may drill them on site.
Reference is now made to Fig. 8. In another embodiment, a stopper element 50, such as but not limited to, a C-shaped collar, may be affixed to locking element 38, such as by a fastener 52 (e.g., a set screw).
Referring to Figs. 6 and 7, a jig 54 may be used to mount the stopper element 50 on the locking element 38. Jig 54 is shaped like the housing 14 (Fig. 5A), so that a tool 56 (e.g., a screwdriver) can be used to tighten fastener 52 of stopper element 50 to fasten stopper element 50 at the correct position on locking element 38. A gripper tool 58 may hold the stopper element 50 at the correct position during tightening of fastener 52.
Reference is now made to Figs. 2A, 2B and 2C, which illustrate auxiliary lock 10 installed in door 36 and stopper element 50 fastened on locking element 38. Fig. 2A illustrates auxiliary lock 10 in an unlocked position that does not prevent movement of locking element 38. In Fig. 2B, auxiliary lock 10 is in a locked position that prevents upward movement of the locking element 38 because locking member 32 abuts against a first surface 51 of stopper element 50 (in this case, the upper surface). In this locked position, the locking element 38 cannot move into a locked orientation. In Fig. 2C, auxiliary lock 10 is in a locked position that prevents downward movement of the locking element 38 because locking member 32 abuts against a second surface 53 of stopper element 50 (in this case, the lower surface). In this locked position, the locking element 38 cannot move into an unlocked orientation. Fig. 3 also illustrates the auxiliary lock 10 mounted in the door and in a locked position as in Fig. 2C.
Accordingly, if the auxiliary lock 10 is in the locked orientation of Fig. 2B, then even if an authorized key is used to try to unlock the locking-element locking mechanism (40, seen in Fig. 3) in order to try to open the door 36, the auxiliary lock 10 prevents movement of the locking element 38 and prevents the door 36 from being opened.
If the auxiliary lock is in the locked orientation of Fig. 2C, then even if the authorized key is used to try to lock the locking-element locking mechanism in order to try to lock the door, the auxiliary lock 10 prevents movement of the locking element 38 and prevents the door from being locked.
Reference is now made to Figs. 10A and 10B. In accordance with an embodiment of the present invention, the auxiliary lock may include a set of locking members of different lengths, such as locking members 32L (32 “long”) and 32S (32 “short”). These locking members can be used to abut against the stopper element or to engage the apertures formed in the locking element of the door. The installer may simply choose one of the locking members of the set with the appropriate length to suit the particular geometry of the door and locking element of the door.
