The present invention relates to a lock for a door, in particular for a rebated door.
Locks for a rebated door are known comprising a containing box body inside which a latch is fitted that is movable from an extracted position, with respect to the box body, to a retracted position in the box body. When the door is closed, with the rebate thereof next to the door jamb, the latch in the extracted position is received in a corresponding cavity obtained on the door jamb, this cavity being bounded by a retaining plate. By a handle that is drivable from the outside it is possible to act on the latch to transfer the latch from the extracted position to the retracted position, in this way making possible the opening of the door. The latch can be of mechanical or magnetic type.
Some locks, for security and privacy reasons or needs, not only close the door normally, but also have a locking function. In particular, a first type of lock has a security key-cylinder by means of which it is possible to lock the latch, preventing driving thereof by the handle. Such a lock, although it is provided with a key-locking function, has a limit represented by the fact that the security locking is performed by a sole element, in this case the latch. Thus, for example in the case of a break-in attempt by an ill-intentioned person, it is sufficient tamper only with the latch to bypass the locking with a key, or stress the door with a push that is more or less vigorous that releases the latch from the respective cavity of the door jamb.
A second type of lock on the other hand, in addition to the normal latch that cannot be locked in the extracted position, provides a bolt and an associated security-key cylinder, the latter being totally decoupled functionally and structurally from the latch. In other words, the security key cylinder acts only on the bolt.
In this type of lock, the key-locked condition is achieved only by the bolt engaged in the respective cavity of the door jamb. In key-locked-door conditions, i.e. with the respective bolt in the extracted position and received in the dedicated cavity of the door jamb, the latch is not locked in the extracted position, being held in this position only through the effect of the preloading stress of a spring inside the containing box body in the case of a mechanical latch, or by the action of magnetic attraction in the case of a magnetic latch. Thus the latch in itself does not constitute any problem in the event of a break-in attempt committable by an ill-intentioned person and the sole obstacle to overcome for the latter is represented by only the bolt. Also for this type of lock, in fact, the locked condition of the door relies on a sole element, in this case the bolt.
As hinted at, in this latter type of lock that has just been disclosed, the two parts of lock relating respectively to the latch and to the bolt are totally decoupled from one another both from the functional and structural point of view, which entails a significant general complexity with a high number of mechanical parts that are necessary for the relative operation thereof.
From DE3504125 a lock provided with a latch and bolt is known. The latch can be retracted into the box casing of the lock by a rotatable pushing member, which is drivable by a handle. The bolt is connected mechanically to a rear locking plate that is movable horizontally by a key cylinder. On the aforesaid rear locking plate a rotatable lever is hinged that returns the latch to the inner position. A substantially rectangular plate is provided that is guided by couplings of the pin-slot type, which transfers a movement of the key cylinder to the aforesaid rotatable lever, and a vertical stop plate, which is movable longitudinally, which in the lowered position, with the bolt extracted, locks the latch in the extracted position. A control plate is further provided, having the shape of an irregular pentagon, which connects the rear locking plate to the vertical stop plate to move the latter according to the movement of the bolt. It is clear that this lock includes a great number of mechanical components that define a driving mechanism that is structurally rather complex, accordingly expensive to make, the mechanical reliability of which, which as known decreases with the complexity and number of parts of a structure, is adversely affected thereby.
From CH671427 another lock is known also having a significant structural complexity and thus being affected by the same drawbacks set out above and by an unsatisfactory level of security provided.
CH446109 relates to another lock that does not however provide the levels of security and versatility that it is desired to obtain.
Another drawback of known locks is due to the fact that the accidental driving of the key cylinder to lock the door when the latter is not actually closed on the respective door jamb entails some problems; in particular, the outward projection of the bolt causes, by bringing up the door to the door jamb, damage to the door jamb, the more serious the greater the impetus with which the door is pushed to the closed position.
In the light of what has been said above, it would be desirable to dispose of a lock having improved features, that is structurally and functionally simplified and at the same time enables, with a key-locking modality, much higher levels of security to be reached than those currently provided by the known locks available.
The object of the present invention is thus to provide a new and different solution for a lock for a rebated door, with a mechanical or magnetic latch, that responds to the aforesaid constructional and functional needs. In particular it is intended to:
This invention aims to achieve the aforesaid objects and to overcome the drawbacks of conventional locks for a rebated, or hinged door.
The invention and some preferential embodiments thereof will be disclosed in greater detail below with reference to the drawings, in which:
A lock 1, 101 according to the invention is disclosed below that is suitable for being fitted, in particular, on an indoor door of the rebated type, i.e. a hinged door, but which can be applied in general in rotatable closing elements of the rebated type.
With reference to
A frontal closing plate 66 is provided that, once inserted the box body 2 inside the cavity of the door, is applied to the front wall 63 fixed by the same screws that fix the lock 1 to the door.
The lock 1 comprises a latch 3 or 3′ that is movable, along an entrance direction DI, between an extracted position E, i.e. protruding outside the box body 2, and a retracted position R in which the latch 3 is positioned inside the box body 2.
The latch 3 or 3′ is suitable for engaging a retaining plate that is mounted on the door jamb at the engaging cavities for latch and bolt.
For the sake of simplicity, (in
The lock comprises a driving device 4 that is movable along an opening direction DA to move the latch 3 from the extracted position E to the retracted position R. The driving device 4 is movable along the aforesaid opening direction DA by a rotatable lever member 14 that is in turn drivable by an outer control handle.
In particular, the opening direction DA is transverse to the entrance direction DI along which the latch 3 is movable.
To move the latch 3 from the extracted position E to the retracted position R, the lock 1 is provided with a motion transferring arrangement (9a, 9b; 10a, 10b, 11), disclosed better below, which transforms a movement of the driving device 4 along the opening direction DA into a movement of the latch 2 in the entrance direction DI.
The driving device 4 is moreover movable by a key-locking-member 5, along a locking direction D8 opposite the aforesaid opening direction DA, to reach a disengaged position PD in which the driving device 4 is disconnected and not engageable by the lever member 14 coupled with the outer control handle. In this manner, driving of the latch 3 is prevented. This disengaged position PD is visible in
The driving device, in particular, comprises a cursor element 4 that will be disclosed in detail below.
The lock 1 comprises a bolt 6 for locking by key the door. The bolt 6, which is drivable by the aforesaid key-locking-member 5, is movable from a non-operative position PN, in which it is retracted into the box body 2, to an operative position PO in which it protrudes outside the box body 2. The key-locking-member 5 in particular comprises a key cylinder provided with a bit element, that is rotatably drivable by inserting a suitable key. In another embodiment, the key-locking-member 5 is defined, instead of by a key cylinder, by a suitable key provided with a stem and a suitably shaped driving portion.
The aforesaid motion transferring arrangement (9a, 9b; 10a, 10b, 11) is now disclosed, which comprises part of the cursor element 4, and part of the latch 3 (or 3′, 3″).
Specifically, the motion transferring arrangement comprises a pushing-portion 9a obtained on an upper zone of the cursor element 4, and a follower-portion 9b obtained on the latch 3 (3′). The pushing-portion 9a is shaped for coming into contact with the follower-portion 9b to push the latch 3 (or 3′) into the retracted position R when the cursor element 4 advances along the opening direction DA. The pushing-portion 9a and the follower-portion 9b are then shaped to slide on one another in reciprocal contact.
In the lock embodiment 1 shown in
In one embodiment (not shown), it is possible to provide, in replacement of just one of the two tilted surfaces 9a and 9b, a wheel portion, or another equivalent solution, which is able to slide on the remaining tilted surface. This possible configuration can also be applied to the lock embodiment 101 that will be disclosed further on.
Still with reference to
The cursor element 4 comprises an abutting zone 15, opposite the pushing-portion 9a, suitable for interacting with the key-locking cylinder 5.
The abutting zone 15 comprises a first abutting portion 16 that is suitable for receiving from the key-locking cylinder 5 a pushing action for the cursor element in the locking direction DB, thus in particular downwards.
The abutting zone 15 comprises a second abutting portion 17 that is suitable for receiving from the key-locking cylinder 5 a further pushing action to move the cursor element 4 in the opening direction DA, thus in particular upwards. The first abutting portion 16 and the second abutting portion 17 project orthogonally to the plane defined by the cursor element 4, in other words parallel to the rotation axis of the key-locking cylinder 5.
The cursor element 4 is further provided with a pin protrusion 20, shaped for engaging with a driving groove 30 obtained on the bolt 6.
The groove 30 comprises a tilted portion in such a manner that a movement of the cursor element 4 in the locking direction DB causes the bolt 6 to protrude to the outside of a length Q. On the other hand, a movement of the cursor element 4 in the opening direction DA is matched by a retracting movement of the bolt 6 to inside the box body 2. A widened zone 35 of the groove 30, placed in a more advanced position, i.e. nearer the front wall 63, disengages the bolt 6 from the pin protrusion 20, enabling it to move by a certain amount equal to half the total length of extracting to the outside. The groove 30 further comprises a locking portion 37, extending orthogonally to the movement direction of the bolt 6. In particular, the locking portion 37, with reference to
The bolt 6, which is housed in a zone approximately comprised between the engaging lug 13 and the abutting zone 15 of the cursor element 4, comprises an extracting abutment 32 shaped for coming into contact with, and receiving a pushing action from the key-locking-member 5. The push of the key-locking-member 5 on the extracting abutment 32 causes the bolt 6 to exit from the box body 2 by a first amount Q. The lowering of the cursor element 4, by the locking member 5, causes the bolt 6 to advance further outside by a further amount—that can be the same as, or different from, the aforesaid amount Q—until the maximum protruding end position is reached, i.e. the operative position Po shown in
In this operative position PO, the bolt 6 protrudes by 20 mm, or another desired amount, with respect to the containing box body 2.
The bolt 6 comprises a return-abutment 33, in a position that is retracted with respect to the extracting abutment 32. The return-abutment 33 is shaped for coming into contact with, and receiving a pushing action from the bit of the key-locking cylinder 5, to return the bolt 6 to inside the box body 2.
The cursor element 4 comprises a locking arrangement (7A or 7B) shaped for locking the latch (3 or 3′) in the extracted position E, preventing forced movement thereof from the outside to the retracted position R, when the cursor element 4 is in the disengaged position PD, disconnected from the lever 14 member. In other words, the locking arrangement (7A or 7B) intervenes to prevent the latch retracting, by an undesired outer action, when the lock 1 is in the key-locking configuration. Thus in the key-locking configuration not only does the possible rotation of the idle handle not have any effect on the latch 3, but any forced movement of the latch is also prevented.
In the lock embodiments I with magnetic latch 3, the locking arrangement comprises a locking ridge 7A shaped for restingly receiving a protruding wall 8 of the latch 3. In particular, the locking ridge comprises a locking wing 7A that projects orthogonally near an edge of the cursor element 4 facing the front wall 63 of the box body 2. In the locked condition with the cursor element 4 in a lowered position in which also the bolt 6 is in a position protruding outside, movement of the latch 3 from the extracted position E to the retracted position R is prevented. It is obvious that in this condition, the zones that are actually locked in the extracted position ensuring locking in total security of the door are two, unlike what occurs with the prior art systems disclosed previously. Further, the protruding wall 8 provided on the magnetic latch 3 has a further function. In conditions with the open door, the magnetic latch 3 is in a non-operating condition, i.e. is freely housed inside the containing box body 2. In this condition, the cursor element 4, by acting by means of the key-locking cylinder 5, is prevented from descending along the locking direction DB; this effect is achieved through the protruding wall 8 which, in the retracted position R of the latch 3, is placed immediately below the locking wing 7A, impeding the movement thereof downwards. The advantageous effect of this configuration is to prevent the exit of the bolt 6 from the box body 2 when the door is not actually drawn against the respective door jamb, thus preventing the latter from being damaged if the door is pushed against the door jamb with the bolt in a protruding position.
The protruding wall 8 enables the cursor element 4 to be moved in the locking direction DB only when the magnetic latch 3, attracted magnetically into the extracted position E, is thus received correctly into the respective cavity of the door jamb.
With respect to the embodiment that has just been disclosed with magnetic latch, the lock 1 that is provided with a mechanical latch 3′ has small differences in terms of the locking arrangement. Substantially, the locking arrangement comprises, instead of the locking wing 7A (which is absent in this case), a different locking ridge, i.e. a turret portion 7B obtained on the summit of the cursor element 4, which also has the function of interacting with the flexure spring 46 that urges the cursor element 4 downwards. The turret portion 7B is shaped for restingly receiving, and locking, a further protruding wall 8′ placed on the mechanical latch 3′.
When the cursor element 4 is in the lowered position, i.e. in the locked condition by key of the lock 1, the turret portion 7B is below the shelf wing 47 on which the flexure spring 46 rests. In particular, the turret portion 7B, being housed in a recess zone 36 of the latch 3′ (
In all the lock embodiments according to the invention, both in the embodiments that have just been described, and in those described below, the locking arrangement 7A, or 7B, are obtained integrally on the cursor element, i.e. they are made as a single piece with the cursor element. In other words, the locking arrangement is part of the cursor element. The locking function of the latch, which is thus assigned to a part of the cursor element, is accordingly performed by an element that is distinct from the bolt, unlike some prior-art locks in which the locking function of the latch is on the other hand assigned to the bolt when the latter reaches the extracted position. The fact that the locking function of the latch is performed by the cursor element, which is totally contained in the box body (2; 102) and thus, not being accessible, is immune to break-in attempts, makes the level of security and resistance to break-ins provided by the present lock much higher than with the type of known lock that has just been mentioned: in the latter case it is possible to act directly on the bolt in an extracted, and thus accessible, position, to tamper with the locking function and thus force the lock, this not on the other hand being possible with the lock according to this invention.
The operation of the lock 1 of this invention is now disclosed concisely.
When the door is open, the lock 1 is in the condition shown in
Once the door has been closed against the door jamb, the magnetic latch 3 is attracted magnetically, for example through the effect of a magnetic element associated with the door jamb, to inside the respective cavity provided on the door jamb. In this manner the protruding wall 8 disengages from the locking ridge 7A, which is thus free to proceed downwards. By starting the rotation of the cylinder 5—anticlockwise with respect to
By continuing the rotation of the cylinder 5, the bit element moves away from the extracting abutment 32 and comes into contact with the first abutting portion 16 of the cursor element 4. The bit element 5 then pushes the abutting portion 16 downwards, in the locking direction DB, thus taking the cursor element 4 to the disengaged position PD in which it is disconnected from the lever 14 coupled with the outer handle. During the lowering of the cursor element 4, the pin protrusion 20 abandons the widened zone 35 and penetrates the narrowest portion of the groove 30 forcing, with a movement descending along the driving groove 30, the bolt 6 to exit by a further amount Q. In this configuration, the cursor element 4 is lowered into the locking position and the locking ridge 7A, i.e. the locking wing 7A, is in a position that is such as to lock the protruding wall 8. In this key-locked condition of the lock 1, any attempt from outside to push the latch 3 (or 3′) to the inside is prevented. The pin protrusion 20, engaged in the locking portion 37 of the groove 30, blocks in the extracted position the bolt 6, preventing any movement thereof caused by possible forcing from outside.
Two elements of the lock are thus locked, i.e. latch and bolt, significantly improving the achievable levels of security. The lock 1 thus permits key-locking and bolt-locking owing to a complete rotation of the cylinder 5.
It should be noted that the bit element of the cylinder 5, in the condition shown in
To open, the opposite procedure is followed. Thus by rotating the cylinder 5 clockwise this time, the second abutting portion 17 is pushed upwards: the pin protrusion 21 of the cursor element 4, moving upwards, forces the bolt 6 to retract, by half a stroke, into the box body 2. By continuing the clockwise rotation of the cylinder 5, the bit element engages the return-abutment 33, which is pushed in the entrance direction DI, making the bolt 6 retract to inside the box body 2.
The cursor element 4 is pushed further upwards, thus beyond the normal rest position, and by contrasting the first flexure spring 46 can also perform the function normally assigned to the handle, i.e. it is able to retract the latch in the containing box body 2 and enable the door to be opened. This is possible owing to the abutting portion 16—obtained on the cursor element 4—which can receive a downward push directly from the bit element of the member 5.
A second flexure spring 48 is provided that by interacting with a cam profile 49 of the cursor element 4, establishes a rest position for the cursor element 4, and supplies a pleasant tactile feedback to the user during driving of the cylinder 5. This tactile feedback signals that a complete opening and closing manoeuvre of the lock 1 has been achieved, giving the user the sensation of performing the various door-locking and unlocking tasks completely and correctly.
In fact, the bolt 106 comprises a first extracting abutment 40, shaped for receiving from the cylinder 5, at a first rotation of the latter, a first pushing action causing the exit of the bolt 106 from the box body 102 by a first amount Q.
The bolt 106 comprises a second extracting abutment 41, obtained in the position that is more retracted than the first extracting abutment 40 and shaped for receiving from the cylinder 5, at a second rotation of the latter, a second pushing action causing the exit of the bolt 106 from the box body 102 by a second amount, which can be the same as or greater than or less than the preceding quantity Q. In the maximum protruding position, the bolt 106 thus protrudes by an amount Q′ that can be, for example, but not in a limiting manner, equal to 22 mm.
The bolt 106 comprises a first return abutment 42, obtained in a rear zone, shaped for receiving from the key-locking cylinder 5 a first push for retracting the bolt 106 by a first amount to inside the box body 102.
The bolt 106 comprises a second return abutment 43, in a more advanced position than the first return abutment 42, and shaped for receiving from the cylinder 5 a second push for completing the retracting movement of the bolt 106 into the box body 102. The bolt 106 further comprises a wall bounded by a mover tilted surface 23 suitable for interacting with a follower tilted surface 22 provided on the cursor element 104, as disclosed better below.
The lock 101 is provided with a further locking arrangement 50, shaped for blocking the bolt 106 in the extracted operative position PO, preventing forced movement thereof from the outside to the inside of the containing box body 102. In particular, the further locking arrangement 50 locks the bolt 106 also in further positions, such as an intermediate protruding position PI, and the non-operative position PN inside the box body 102.
The further locking arrangement 50 comprises a pawl member 50, which is rotatable around a rotation axis AR, and configured for locking the bolt 106 in various positions preventing forced movements thereof from the outside. The pawl member 50 is drivable by the bit element of the key-locking-member 5 that lifts the pawl member 50 upwards to transfer the pawl member 50 from a locked configuration—in which it locks any movement of the bolt 106—to a release configuration that permits the translation exit or entrance of the bolt 106. On the bolt, a locking groove 51 is obtained having a toothed profile with three distributed recess zones 52, shaped for coupling with a tooth 53 of the aforesaid pawl member 50. With reference to
The cursor element 104 is now disclosed that differs from the embodiment disclosed previously through a different geometrical configuration of the abutting zone 15 and of the protrusion element 21.
The cursor element 104 comprises an abutting portion 16′ that is suitable for receiving from the key-locking-member 5 a pushing action by which the cursor element 104 is moved in the locking direction DB. In this case an upper abutting portion is missing that is on the other hand present in the cursor element 4 of the preceding embodiment.
The protrusion element 21 in this case comprise a protrusion with a polygon-shaped section. The protrusion 21 comprises a follower tilted surface 22, which has already been mentioned previously, which is shaped for slidingly engaging with the mover tilted surface 23 obtained on the bolt 106. The mover 23 and follower 22 tilted surfaces are shaped so as to impose on the cursor element 104 an upward movement in the opening direction DA when the bolt 106 is returned to inside the box body 102. Thus unlike the lock 1, in the lock 101 it is the bolt 106, which is in turn pulled by the cylinder 5, which pushes upwards the cursor element 104 during the step of unlocking and opening the lock 101.
For the locking function performed by the protruding wall 8 and by the locking ridge 7A, what was disclosed previously for the first lock embodiment 1 applies similarly.
The operation of the lock 101 is now disclosed briefly, omitting the description of parts that, being very similar both functionally and structurally to the lock embodiment 1, have already been disclosed previously.
Starting from the open condition shown in
The protruding wall 8 thus leaves the locking ridge 7A freedom of movement downwards. By starting rotation of the cylinder 5 (anticlockwise in
Both the latch 3 (or 3′) and the bolt 106 are thus blocked in the protruding position.
To open, the reverse procedure is followed. By rotating the bit element of the cylinder 5 this time clockwise, first the first return abutment 42 is engaged, with simultaneous lifting of the pawl member 50. The bolt 106 is thus retracted within a half stroke. At a subsequent rotation, the bit element 5 engages the second return abutment 43, to push the bolt 106 by a further half stroke to inside the containing box body 102. During this subsequent return movement of the bolt 106, the mover tilted surface 23, after coming into contact with the follower tilted surface 22 of the cursor element 104, pushes the latter upwards, returning the cursor element 104 to the rest condition in which it is engageable by the lever member 14 that is drivable by the handle. Upon completion of two rotations of the cylinder 5, the bolt 106 has reached the retracted non-operative position PN. Also in this case, by possibly continuing to rotate the cylinder 5 clockwise, the bit element can come into contact with, and lift the abutting portion 16′ to retract the latch 3, thus also performing the function normally performed by the outer handle.
According to this configuration, the motion transferring arrangement comprises a pushing-portion 10a obtained on the cursor element 204, a follower-portion 10b obtained on the latch 3″, and a rotatable lever member 11 interposed between the aforesaid portions 10a and 10b.
The pushing-portion 10a and the follower-portion 10b in particular comprise respective surfaces that are arranged according to horizontal planes orthogonally to one another. In particular, the pushing-portion 10a comprises a surface arranged substantially orthogonally to the opening direction DA in which the cursor element 204 is movable, whilst the follower-portion 10b comprises a surface arranged substantially orthogonally to the entrance direction DI in which the latch 3″ is movable. The lever member 11 is rotatable around an axis A1 that is orthogonal to the plane defined by the aforesaid opening direction DA and entrance direction DI and comprises appendages 12a and 12b suitable for engaging respectively the pushing-portion 10a and the follower-portion 10b. The appendage 12a receives the push from the cursor element 204 whilst the appendage 12b transfers the push to the follower-portion 10b: in this manner a movement of the cursor element 204 along the opening direction DA is transformed into a movement of the latch 3″ along the entrance direction DI.
All the embodiments disclosed above provide a cursor element that is movable linearly along a rectilinear trajectory. More precisely, the cursor element is movable linearly in the locking direction DB and in the opening direction DA orthogonally to the entrance direction DI of the latch.
From what has been disclosed and shown in the drawings it is clear that the lock 1, 101 according to the invention enables the declared objects to be achieved. In particular, a new lock solution for a rebated door is provided, with a mechanical or magnetic latch, which ensures greater levels of security in the key locked condition of the door. The disclosed lock according to the invention is constructionally simpler, with a reduced number of mechanical components, thus much more reliable than prior-art locks with bolts, in which the two lock parts relating respectively to the latch and to the bolt are totally decoupled from one another, both from the functional and structural point of view, with consequent great general complexity and a great number of mechanical parts.
In particular, the lock according to the invention is equipped with the cursor element (4; 104; 204) which is able to perform many functions.
In other words, a sole mechanical driving element, i.e. the cursor element (4 or 104 or 204), is able to:
Further, when it is desired to open the door, with a suitable rotation of the key-locking-member 5, the cursor element (owing to the presence of the abutting portion 16 or 16′ obtained wholly thereupon) is drivable directly, without interposed elements, by the member 5 so as to retract inside the latch without necessarily acting on the handle, with the advantage of greater versatility of the lock. In other words, the cursor element is geometrically configured so as to be able to connect operationally directly the key-locking-member 5 with the latch in the door opening operation. The result is clearly a great structural simplification of the lock.
The significant structural simplification, together with the particular configuration of the cursor element provided with the locking arrangement for the latch, and the significant length of protrusion of the extracted bolt (double extraction) enable high levels of security to be obtained for the lock that have never been reached by known locks.
What has been said and shown in the attached drawings has been provided to illustrate the innovative features of the lock 1, 101 for a rebated door according to two possible embodiments.
Modifications can be made to the lock or to parts thereof without thereby falling outside the scope of the claims.
In practice, the materials, inasmuch as they are compatible with the specific use and with the respective single components for which they are intended, can be chosen opportunely according to the required requisites and according to the available prior art.
It is moreover possible to configure and dimension the lock and adopt materials according to need and possible variations on and/or additions to what has been disclosed and illustrated in the attached drawings are possible.
