Door lock 10 also has anti-feature of locking, thereby can start anti-lockout mechanism, so that prevent if door inadvertently is locked into the outside with the people when unexpectedly closing with a bang.Anti-lockout feature is also set during installation.

Accompanying drawing shows mortice lock 10, and this mortice lock is suitable for being installed in the mortise (not shown) of door, is visible thereby positive 11 (Fig. 1 (b)) are only arranged.The rear portion 21 of mortice lock 10 has been shown among Fig. 1 (c).This mortice lock has the housing 12 of the functional unit that holds mortice lock 10.This mortice lock has all common features that can find in the mortice lock that comprises main dead bolt 13, this main dead bolt is carried by bolt bracket 29 and can move with dead bolt (dead latchpin) 14.

Pin 14 is designed to extend to outside the housing, and helps door lock due to doorframe, and externally handles under the situation of dead bolt 13 standby security feature is provided.When opening, pin 14 unclamps, and is withdrawn in the housing together with dead bolt 13.

Actuation gear releases pin 14 also is withdrawn into dead bolt 13 in the mortice lock housing 12, so that door is opened.Actuation gear is the form of split hub handle actuator 15, and each actuator can be actuated by the corresponding door handle (not shown) on the door either side.The split hub handle actuator makes a handle can be independent of another handle and operates door lock.

The square department 17 that is positioned at each actuator 15 central part holds the axle (not shown), so that split hub 15 can be rotated by corresponding handle.Actuation arm 54 on each actuator 15 engages with bolt flange 16 when actuator 15 rotates, thus release pin 14 and main dead bolt 13 is withdrawn in the housing 12, to open/to open door.

Spring 18 is towards main dead bolt 13 is kept from the positive outstanding direction bias voltage hub actuator of mortice lock.Main dead bolt 13 self is biased into outstanding from the front by latch bolt spring 55.Latch bolt spring 55 is contained between bolt bracket 29 and the housing 12.Bolt bracket 29 is connected with main dead bolt 13 integratedly with bolt flange 16, to move with main dead bolt 13.

Handle selection mechanism is located towards the rear portion of mortice lock, and does not optionally engage with any one hub actuator 15 or engage with one or two hub actuator.Handle selection mechanism is by key-driven cylinder lock 19 operations.Replacedly, key-driven cylinder lock 19 can be by being replaced by the adapter of thumb turn or similar means driving.Present described embodiment shows key-driven cylinder lock.

Handle selection mechanism comprises elongation formula locking bar 20, and this locking bar is directed, to slide between open position shown in Fig. 1 (a) and lock position shown in Figure 2 in housing.

In the time of in that open when being in, the inoperative position, locking bar is not interfered actuator 15, and the handle of door on the both sides can freely rotate, with release pin 14 and main dead bolt 13 is withdrawn in the housing 12.When in the lock position that is in reduction, left hand and right hand detent 22a and 22b can be adjusted to and optionally not interfere any one handle actuator 15 or interfere one or two handle actuator, thus make two actuators can open the door, only have an actuator can open the door or any actuator all can not open door.Fig. 4 shows locking bar and parts in the mode of exploded view.

Locking bar 20 also comprises outstanding stop part 57, and this stop part outwards is biased into outside the locking bar 20 by spring 59.In two stop recesses 58 in stop part 57 and the housing 12 one of them engages.Recess 58 limits the upper and lower position of locking bar 20 respectively, that is, open and the lock position.Recess 58 prevents that locking bar 20 from slipping over these terminal positions.

When locking bar 20 applied up or down power, this stop part 57 that makes of making every effort to overcome clothes spring 59 was projected into the spring force in the recess 58, thereby stop part 57 moves inward locking bar 20, therefore makes locking bar move up or down.Stop part 57 has leg-of-mutton pointed profile, thereby the inclined side of stop part 57 can slide on the matching surface in recess 58 under an amount of power effect, and overcomes the spring force of stop part 57.

Locking bar 20 is lowered by the key that is inserted in the cylinder locks 19, and is right-hand so that cylinder locks 19 is turned to, shown in the arrow A among Fig. 1 (a).Rotate cylinder locks 19, engage with lower reaction surface 25 on the locking bar 20 until the little cam 23 on the cylinder locks 19.The rotation impetus surface 25 of cylinder locks 19, and make locking bar 20 slide in the lock position downwards, shown in the arrow B among Fig. 1 (a).

On the sidepiece relative with cylinder locks 19 that big cam 27 is positioned at mortice lock, this big cam can be actuated by another cylinder locks or thumb turn (not shown).Therefore, big cam 27 is actuated by the side relative with little cam 23 from door.When the counterclockwise in Fig. 1 (a) rotated, big cam 27 engaged bolt flange 16, so that dead bolt 13 is withdrawn in the housing 12, made door be opened.Use key to open which side of door (the normally outside) and wish which side (normally inboard) to be provided with latch functions, can exchange the position of big cam 27 and little cam 23 according to hope.

Following action face 25 is positioned at the upper end of locking bar 20.Left hand detent 22a and right hand detent 22b are positioned at the lower end of locking bar 20.

Brake component

22a, 22b can slide independently along the longitudinal direction of locking bar 20, thereby brake component can move process locking bar 20 and be projected into such point,, interferes a corresponding left side and/or right handle actuator 15 at this some place's left hand and/or right hand detent that is.Brake component is only just interfered actuator when they are in the lock position of reduction.In the lock position, brake component will prevent 15 rotations of corresponding handle actuator, and prevent that dead bolt is withdrawn in the housing.That is, pin door effectively from respective side.

Handle by the door of locking is corresponding with the brake component 22a or the 22b that are reduced to the lock position.For example, reduce right hand detent 22b and can prevent that the actuator 15 that combines with right door handle (not shown) from rotating.Thereby the right side of door is lockable, and can not be operated to open door.In this example, left hand detent 22a is held and is elevated in the open position, and this left hand detent is not interfered left handle actuator, and makes left handle actuator rotate in response to the rotation of left handle.

By handle selection mechanism, door can be opened from a side, and can not be opened from opposite side.The handle of door can be adjusted to or pin the left side as required or pin the right side or even pin both sides, thereby door only can be opened by the key that is inserted in cylinder locks 19 and rotate in this cylinder locks.

Before being inserted into door lock 10 in the mortise,

regulate brake component

22a and 22b by pushing corresponding sprung push buttons 30a and

30b.Button

30a, 30b are arranged in the button recesses 32 of each brake component.Button is biased into outside the recess 32 by spring 35, gives prominence to pass the hole 34 in the locking rod 20.When being in resting position and be biased into outside the hole 34, the narrower throat 37 in each hole 34 is as the stopper section, and this stopper section prevents button 30 displacements and prevents that

brake component

22a, 22b from carrying out any slip in locking bar.But these holes do not need narrower throat is set, and brake component can move in oval-shaped hole.

In order to change the handle of door lock, by pushing

corresponding button

30a, 30b respective detent is slided up or down in locking rod 20, so that remove throat 37, and use button to come manually stopper slides in the structure that raises or reduce.Button can be designed to be pushed and move by pointed tool.As shown in the figure, button comprises centre bore 39, in this centre bore, can be captured and be used for the slip brake part such as the pointed tool of nib or specialist tools.Replacedly, button can be configured to allow to be handled by operator's finger.For example, button can have such feature, promptly makes the part of button can be pulled outwardly moving or upwards outwards upset, so that button is by clamping manually.

For with the side opening of door, use the key (not shown) so that locking bar 20 is elevated to open mode from the locked hand actuator.Key is inserted in the cylinder locks 19, rotates cylinder locks with (when watching as Fig. 2) in the counterclockwise direction, thus the top action face 26 that little cam 23 engages on the locking bars 20.This operation makes locking bar 20 slide in the open mode of rising, thereby discharges blocked handle actuator, make handle to be rotated and the door be opened.

If the handle actuator on the opposite side of door is also locked, then by rotating big cam 27 (along the counter clockwise direction among Fig. 2), also main dead bolt 13 is withdrawn in the housing to enforce bolt flange 16, and the door handle on the described side that turns the handle then, and open door.

If handle actuator is not locked, then Men described side can be opened by turning the handle simply.

The anti-lockout feature of mortice lock is to realize by the anti-lockout mechanism 40 that is carried on the locking bar 20.Especially, when locking bar moved to the lock position of reduction by cylinder locks 19, anti-lockout mechanism worked, thereby in the handle actuator 15 one or two may be locked.If be in this situation, door can inadvertently be closed so, thereby the people may be locked in the outside and not have can not to open door under the situation of key.By locking bar 20 is elevated to inoperative position, make that two handle actuator help to be withdrawn into dead bolt 13 in the housing and then to open door, so anti-lockout mechanism can prevent from the people is locked in the outside.

Anti-lockout mechanism 40 comprises lockout member 42, and this lockout member can vertically moving between " opening " position of off-position that raises and reduction along locking bar 20.Thereby, usually when mortice lock is installed, can will prevent that back locking function is arranged to open or close.Lockout member can move by locking button 44, and this locks the button recesses 45 that button is arranged in part 42, and passes locking bar hole 46 and protrude in the outside.Button 30a relevant with 22b with brake component 22a and the principle of 30b are similar, lock button 44 by spring 47 bias voltages to extend to outside the hole 46.The narrower throat 37 (Fig. 4) that is arranged in the center in hole 46 remains on lockout member 42 " opening " or the off-position that sets.

Lockout member 42 is laterally extended from locking bar 20 longitudinally, and extends to the inside of housing 12, so that extend towards main dead bolt 13.Lockout member 42 has the inclined plane 49 at diagonal angle, this inclined plane corresponding to and be parallel to similar inclined plane 51 on bolt bracket 29 ends.Bolt bracket 29 is installed on the main dead bolt 13, and by its carrying.

Inclined plane 49 on the lockout member 42 and the inclined plane 51 on the bolt bracket 29 are designed to engage.Particularly, when lockout member is lowered to " opening " position and locking bar is lowered to latched position when (as shown in Figure 3), the inside motion of the main dead bolt 13 that is caused with respect to closing carelessly of doorframe by door will make bolt bracket 29 engage angled surface 49 and apply power upwards on inclined plane 49.Should power upwards make locking bar 20 slide rearwardly to not operable position by lockout member 42, thus all locking actions on the release handle actuator 15.

Preventing that not under the situation of back locking function, closing carelessly of door may make that one or two handle actuator is inoperative, and door only can be opened by using the key in the cylinder locks 19.But under the effective situation of anti-back locking function, the closing motion of door will make bolt bracket 29 that locking bar 20 is made progress and be pushed to safely in the open position of the ownership moving part of having removed handle actuator.In case door is inadvertently closed, and can locking bar 20 be moved backward in the lock position by key-driven cylinder lock 19 so.

Door lock of the present invention provides a kind of being used for that handle is arranged at simple and uncomplicated mechanism on the door lock.Described handle is provided with by entering lock 10 rear portion 21, if only during installation or with mortice lock when the lateral edges of door screws down and is pulled out to outside the mortise, just can enter described rear portion.Therefore, all can not modify handle unilaterally from any sidepiece or the front of door.

This mortice lock also provides the advantage of anti-lockout mechanism, and this anti-lockout mechanism only makes when door is closed the reveal that can set in advance with key lock safely.This has been avoided inadvertently the people being locked into outside the locked hand side of door.

Mortice door lock provides a kind of safe and economic device, and this device is selected desirable locked component, and has avoided any chance of modifying unilaterally.

It will be understood by those skilled in the art that under the prerequisite that does not deviate from the spirit and scope of the present invention, can carry out multiple modification.
