Description

The present invention relates to a lock having a latch bolt and a manually actuable actuation member which are in operative connection with one another so that the la ich bolt is movable írom an extended position into a retracted position and vice versa by actuating the actuation member when the lock is in an unlatched stale, and having a blocking element by which a retraction of the iatchboit Is prevented when the lock is in a locked state..

Locks of this kind are in particular used in doors, hut can also he used in windows or the like. These locks can furthermore be both conventional single-latch locks and, tor example:, three-latch locks or the Ike which typically comprise a so-called math lock and one or more secondary locks. With a single-latch: lock or with a mam lock of a multi-latch lock, the actuation member is typically formed by a handle, whereas with a secondary lock the actuation member cart be formed, for example, by a part: of a drive rod or by an adjustment member coupled to the drive rod.

Miami ally actuated locks have to withstand a minimum handle torque of, for example, 60 Nm in the latched state; according to applicable standards, if a break occurs within the lock on this strain or if one or more lock parts yield within the lock on this strain, the applicable standard is mi satisfied. Since the Iatchboit is blocked against retraction in the locked state of the lock, the force applied via the handle in the test of the lock thus acta on. the. lock elements which are arranged within the lock between the actuation member and the Iatchboit and which operatively connect them to one another. So that the applicable standard can be satisfied, it has previously been customary to dimension all the elements present in the operative connection between the actuation member and the: Iatchboit such thai: the forces and torques, which occur cannot result in any destruction or in any yielding within the lock. The manufacturing costs for the locks satisfying the applicable standards are increased due tills excessive dimensioning:. The excessively dimensioned lock elements furthermore requ ire relatively large space requirements. CH 316 665 A discloses a lock in which a handle operates a latch via. means which can he brought by a key into a position in which they lock the latch: in an advanced position and cancel the connection between the handle and the latch,, it is an object of the present invention to provide a lock of the initially named kind in which the lock elements arranged between the actuation member and the latchbolt can be dimensioned smaller and in which the required stability of the lock, is nevertheless ensured.

Starting from a lock of the initially named kind, this object Is satisfied in accordance with the Invention in that the operative connection between the actuation member and the latchbolt is weakened or Interrupted In the locked state of the lock.

Instead of thus over-dimensiomng the lock elements exposed to the high force on a corresponding actuation of the actuation member, the operative connection between the actuation member and the latchbolt. is weakened or interrupted In accordance with the invention by the locking of the lock so that the actuation member and thus the handle are not blocked despite the blocked latchbolt, but can rather he operafed normally, that is as with an unlocked lock. The torque applied in accordance with the applicable standard thus acts via the handle only on the handle nut which Is generally accordingly dimensioned to withstand the specified torque values. The weakening or interruption of the operative con nectinn between the actuation member and. the latchbolt can in this respect represent a complete Interruption, of the mechanical coupling between these elements or ohly an interruption or a redaction of the force transmission within the mechanic^ coupling by which. It is'ultimately achieved in the sanie man tier that a torque applied to the actuation member is no longer transferred to the latch bolt without impediment.

In accordance with the invention, the operative connection between the latchhoit and the actuation member comprises a drive gear' element, which is rotatable or pivotable about a rotation axis or a pivot axis, with, the rotation axis or pivot axis being displaceable transverse to the axial direction in the locked state of the lock. Whereas the force acting on the actuation member is substantially completely transmitted to the latch bolt via the rotutionally or pivotably supported drive gear element in the unlocked state of the lock to achieve a retraction of the latchbolt, the rotation axis of pivot axis is displaced transverst? to the axial direction due to the applied torque in the locked stab? of the lock so that a substantial force transmission to the latchbolt no longer takes place. The force transmission does not in this respect have to be completely interrupted, but it is rather the ease that a. pari: of the drive gear element can be supported at the blocked latchbolt in order thereby to allow the displacement of the rotation axis or pivot axis transverse to the axial direction.

In accordance with: the invention, the displaceability of the rotation axis or pivot axis is limited in the unlocked state of the lock by a bounding element in operative connection with the blocking element, it is ensured by the operative connection between the blocking element ami the bounding element that when the lock is unlocked, on which the blocking element is moved from a blocking position into a release position, the bounding element is automatically brought Into a position in which the displaceability of the rotation axis or pivot axis is limited and the rotation axis or pivot axis cart thus substantially only carry out a rotation movement or a pivot movement in the unlocked state of the lock. Since an escape movement of the rotation axis or pivot: axis is prevented in this manner, an actuation of the actuation member is converted into a corresponding rotation movement or pivot movement of the pivotably supported drive gear element which in turn effects a retraction .of the latehboit.

In accordance with the invention, the rotation axis or pivot axis is substantially non-dispiaeeabie in the unlocked state of the lock. The rotation axis or pivot axis can in this respect he completely non-dispiaceahle, that is; it can only be rotatable or pivotable, or a slight displaoeability can also he possible, with this displaceahility, however, being smaller than the displaceahihty in .the· kicked state of the lock.

In accordance with the invention, at least one guide section, is provided in which the rotation axis or pivot axis is displaceabiy guided in the locked state of the lock. Ä defined displacement of the rotation axis or pivot axis along the guide section is achieved in this manner. The guide section can hr particu lar he provided in or at a housing, sec tion of a lock housing.. The ends of the relation axis or pivot axis can be guided, for example, in corresponding recesses in the housing section.

The drive gear element is preferably formed as a; pivot: lever. The pivot {ever can in this respect comprise two lever arms connected to one another in an articulated manner and one of the two lever arms can he pivotably supported about the rotation, axis or pivot axis, in this respect, the free end of the one lever arm can comprise an engagement section which is configured for displacing the latchbolt into the retracted position, â contact section which the engagement section contacts at least on the: displacement of the latchholt Into the retracted position can correspondingly be formed at the latch holt. The free end of the other one of the two lever arms can be operatively connected to the actuation member. It. is achieved in this manner that, on the actuation of the actuation member, the pivot lever is pivoted about the rotation axis or pivot axis, when?by the engagement section of the pivot lever comes to fie at the contact section, of the iatohholt and the ia.tch.bolt is thereby displaced into die retracted position if the lock is in its unlocked state.

The drive gear clement Is formed as a toothed wheel in accordance with a farther subject of the invention in accordance with the independent claim. The toothed wheel can., for example, he rotated abou t the rotation axis or pivot axis via a sprocket: connected to the handle nut or via another drive gear element actuabie via the actuating element and can be in operative connection with a further drive gear element, for example a further toothed wheel or a gear rack, in operative cooperation with the latchholt The rotation axis or pivot axis is displaeeahly guided in at least one guide section. In the unlocked state of the lock, an actuation of the actuation member thus effects a rotation of the toothed wheel, which in turn effects a corresponding retraction of the latchholt, On switching over the lock from the unlocked state Into the locked state, In contrast, the rotation axis or pivot axis of the toothed wheel is displaced transverse to the axial direction such that the toothed wheel comes out of engagement with the drive gear element cooperating with it at the input side, at the output side or at the input side and the output side so that the operative connection between the actuation member and the lafchholt is interrupted.

In accordance with a further advantageous embodiment of the invention, a spring element is provided by which the latch bolt is urged hack from the retracted position into the moved out position. If is generally also possible that, for example* a spring element is provided which acts on the actuation member or on a. drive gear element connecting the latehbolt. axxl the actuation member arid the latehbolt. is brought into the extended position oh the retraction of the actuation member into its starting position by a corresjxrnding mechanical coupling.

Further advantageous embodiments of the invention are set forth in t he dependent claims.

In the following Figures elements which correspond to one another are also each designated fey the same reference numerals in different embodiments.

Fig. 1 shows a door I having a three-latch lock 2 which, comprises a main lock 3 and two secondary locks 4 which can fee of identical design..

The main lock 3 comprises a handle S via which a latchbolt 6 can fee moved in a conventional manner from an extended position shown in Fig. I. into a retracted, position in that the handle S is pivoted, downwards about a handle nut 7. When moving back into the starting position, the iatchfeolf 6 is moved back into the extended position ín a known manner by spring force assistance.

The movement, of the handle 5 Is respectively transferred via a drive rod 8 to the secondary locks 4 which have latcbholts 9. The latchboits 9 are can pied to the handle 5 via the drive rods 8 such that they can be moved in parallel with the latchbolt 6, that is they can be switched between a retracted position and an extended, position.

The main lock 3 .furthermore comprises a lock cylinder 10 via which the three-latch, lock 2 can be locked, in this respect, in the locked state of the three-latch lock 2. both the main lock 3 and the secondary locks 4 are locked. 1rs the locked state of tin; main lock 3 and of the secondary locked, the latchboits 6, 9 are each arranged in the extended position and are blocked against a pressing back into the retracted position. Bar exclusions 11 as well as, in particular at the main lock: 3, locking bolts 12. or other holt dements can furthermore additionally fee provided for locking: the door 1, The control of the bolt elements, that is the blocking of the latchboits 6, 9 or the extending of the locking bolt 12 and of the bar •exclusions 11., takes place m this respect in a conventional manner via latch bars 13 or via lock drive gear elements provided within the main lock 3 and the secondary locks 4.

The invention will he described in more detail in the following with reference to two embodiments which each show the design et a secondary lock. The invention, can in principle also be used in an analogue manner In a. main lock. The main difference can in particular he found in that a lock cylinder is present in a main lock via which the locking of the main lock takes place directly, whereas with the secondary locks the; locking respectively takes place via the bolt bars starring from the lock cylinder of the main lock, A. first embodiment of a. lock 14 hi aceordanee with the invention is shown in four different positions in Pigs, 2 to 5. The lock .14 has a lock housing 15 of which only a lock cover 16 is shown in the Figures which is located in the bottommost plane of the plane of the drawing. The lock cover 16 comprises at its longitudinal side a section which extends perpendicular to the plane of the lock cover and which forms a rear wall 1? of the lock housing 15, To form the lock housing IS», a..further counter-lock cover is provided which corresponds to the lock cover 16, which is not shown in the Figures and which can he connected to the lock cover such that the individual lock elements described in the following are arranged between the two lock covers.

The latch bolt 9 is arranged in the middle region of the lock 14 and is guided by two guide sections 18, 19 which are: formed, for example, írom stampings In the lock cover 16 for displacement In accordance with a double arrow 20 from the extended position shown in. Fig, 2 into the retracted position shown In Fig, 3, The guide section 1.9 in this respect, has at its rear end a section 21 which, m angled by 9CF and which forms a rear end abutment for the latch boh 9, A spigot 22 onto which a spring element 23 formed as a .spiral spring is poshed is fastened to the lock: cover 16, Whereas one free end 24 of the spring element 23 is supported at the rear wall 17, the other free end 25 Is longer and contacts a rear section 26 of the latch bolt 9 such that it. is urged from the retracted position shown in Fig, 3 into the extended position shown In Fig. 2,

The latchbolt 9 furthermore comprises a contact, section 27 which an engagement section 28 of a lexer arm 29 contacts, The lexer arm. 29 m pivotably supported about a rotation axis or pivot axis 30 formed as a spigot whose free ends are guided in two arcuate longitudinal slits 31 from which a respective one is formed in the lock cover 16 and the other is, formed in the counter-lock cover, not shown.

The lever arm 29 is furthermore connected via a joint 32 arranged at its end disposed opposite the engagement section 28 to a further lever arm 33 which Firms a pivot, lever 34 together with the lever arm. 29,

Whereas the lever arm 33 is substantially former! in a straight line, the levet' arm 29 has an L-shaoed or J-shaped design so that the lever arms 29 and 33, as shown in Fig. 2,. can be pivoted with, respect to one another via the joint 32 such that they extend substantially in parallel with one another, I'he free end of the lever arm 33 is connected in an articulated manner via a pivot axle 35 to an elongated fiat control member 36 which has coupling section 37, 38 at its two ends for coupling to the drive rod 8. The control member 36 Is guided in accordance with a double arrow 39 towards: a guide provided displaceable In a counter-lock cover, not shown. On the other hand, an elongate hole 40 is formed in the control member .36 and a spigot 41. fastened to the lock cover 16 and to the: counter-lock cover, not shown, engages Into it for a limited guidance of the control member 36,

An edge 42 facing the front end of the latehboli 9 is formed at the rear section 26 of the iatchholt 9 and comes info contact with a longitudinal side 43 of the control member 36 with an extended iatchholt, whereby the extension of the latchboit § is limited, A flat, elongated, adjustment member 49 which is likewise longitudinally displaceable supported In accordance with the double arrow 39 is arranged between the Iatchholt 9 and the lock cover 6, The adjustment member 44 hi this respect.: cooperates, on the one hand, with guide elements, not shown, provided at the lock cover 16 and, on the other hand, has an elongate hole 45 into- which the: spigot. 41 engages for guiding the adjustment member 44,

Coupling sections 46, 47 which are configured for connecting the adjustment member 44 to the latch bar 13 or to the bar exclusion 11 are In turn formed at the two ends of the adjustment member 44, A blocking element 48 which comprises a contant section 49 is furthermore fastened to the upper end of the adjustment member 44, A guide section 50 in the form of a groove is furthermore provided at tin? side of the blocking element 48 feeing the lock cover 1.6, said guide section cooperating with, a guide element 51 formed at the lock cover 16 and ensuring a guided displacement of the Mocking element 48 together with the adjustment member 44 on a movement of the adjustment member 44 corresponding to the double arrow 39 . Ä run-on chamfer 52 is formed at the end of the adjustment member 44 disposed opposite the blocking element 48 and merges into a bounding edge 53 of the adjustment member 44 extending substantially in parallel with the direction of displacement in accordance with the don hie arrow 39. As can be seen from Fig, 2, the bounding edge 53 is arranged in this respect suck that the lower section of the adjustment member 44 forms a bounding element 54 lor the rotation axis or pivot axis 30 so that it can only he rotated about its longitudinal axis, hut cannot be displaced in the arcuate longitudinal slit 3.1. In the position shown in Fig. 2. Ä spigot 55 which, fortes an. upper abutment, for the blocking dement. 43 is provided at the lock cover 16 In the upper region in Fig. 2. Both the spigot 55 and the spigots 41 and 22 each have a. threaded bore into which the screws can he screwed for fastening the counter-lock cover, not shown. Another fastening, for example a rivet connection, is also possible.

The operation of the lock 14 configured in accordance with the invention will be described in. more detail in. the following with reference to the different states of the lock 14 shown. In. Figs, 2 to 5,

Fig. 2 shows the unlocked state of the lock 14 in which the handle 5 is in its horizontal position and In which the latchholt 9 Is arranged in the extended position,

On actuating the handle 5 to open the unlocked door 1, the rotational movement of the handle 5 Is converted within the main lock 3 into a corresponding translator}' movement of the drive rod 8, This translator}? movement is converted into a, displacement of the control member 36 via the coupling section 37 so that it is displaced upwardly up to and into the position -shown in Fig, 3 in accordance with the upper half of the double arrow 39,

The: pivot axle 35 of the lever arm 33 is also accordingly displaced with the displacement of the control member 36* whereby a pivoting' of the lever arm 29 connected in an articulated manner to the lever arm 33 takes place aboui the rotation axis or pivot axis 30 in accordance with an arrow 56 (set; Fig. 3) until the lever arm 29 is in the position shown In Fig. 3,

On this movement of the lever arm 29, its engagement section .28 presses the contact section 2? of the- latchbolt 9 and thereby presses the lock bolt 9 against the spring force of the spring element 23 in the direction of the rear wall IT so thai: the latchbolt 9 ultimately adopts the retracted position shown in Fig, 3 and the door 1 can he opened in a conventional manner,

Since the adjustment.member 44 Is not moved out of its original position shown in Fig, 2 in this procedure, the bounding edge S3 prevents a migrating: of the spigot 30 .into the arcuate longitudinal, slits 31 so that the lever arm. 29 can only oarry out the described pivot movement

On e. moving, hack of the handle 5 into its starting position, the control member 36 is again displaced via the drive rod 8 from the position shown In Fig, 3 into the position shown in Fig. 2, whereby the lever arm 33 and the lever arm 29 connected thereto are also again pivoted into- the position shown In Fig, 2, In this respect, due to the spring force of the spring element 23* the latchbolt 9 is displaced into its extended position shown in Fig, 2 .until- the edge 42 formed at the rear .section 26 of the latchbolt 9 again comes into contact with the longitudinal side 43 of the control member 36.

On the locking of the main lock 3 via the lock cylinder IÖ, the corresponding rotational movement of the lock cylinder Is converted into a translators movement of the latch bar 13 whose movement over the coupling section 46 effects a corresponding longitudinal displacement of the adjustment member 44 in accordance with an arrow ST (Fig, 4) until the adjustment member 44 has reached the position shown in Fig. 4. At the same time, the blocking element 48 connected to the adjustment member 44 is likewise displaced in the direction of the arrow 57 such that the part of the Mocking element 48 comprising the contact section 49 comes to Me in the region between the rear section 26 of the latchbolt 9 and the rear wall 17.: The contact section 49 is configured in this respect such that It comes Into contact with the rear section 26 of the latchbolt 9 so that a retraction of the latchbolt 9 Is prevented by the blocking element 48, as can be seen from Fig, 4 which shows the locked position of the lock 14,

On the displacement of the adjustment member 44 ín the direction of the arrow ST, its end forming the bounding element 54 is also correspondingly downwardly displaced so that, the hounding edge 53 no longer contacts the rotation axis or pivot axis 30, as can likewise he recognised from Fig. 4,

If the handle 5 is pressed downwardly in this locked state of the lock 14, this movement is in torn transferred via the drive rod 8 onto the control member 36 so that It, as described with reference to Figs, 2 and 3, is longitudinally displaced up to and Into the position shown in Fig, 5 in accordance with the upper half of the double arrow 39. The pivot axle 35 and thus also the lever arm 33 Is displaced together with the adjustment member 36 so that, as described with reference to Figs. 2 and 3, the lever arm 29 connected to the lever arm 33 in an articulated manner would also want to carry out a pivot, movement about the rotation, axis or pivot axis 30 in which the engagement 'section 28 of the lever arm 29 presses against the contact section 2? of the latchbolt 9, Since a displacement of the latchbolt 9 in the direction of the rear wall 17 is, however, prevented by the blocking element 48 and at the same time the bounding edge 53 no longer contacts the rotation axis of pivot axis 3D in the locked state, the latter can be displaced transverse to its axial direction within, the circular longitudinal slit 31 until it reaches the position, shown in Fig, 5,

The operative connection between the handle 5 or the control member 36 and the latchbolt 9 is thus interrupted or weakened by the displacement of the rotation axis or pivot axis 30 so that the torque applied via the handle 5 does not act on the blocked latchbolt 9 and none of the lock parts are exposed to the high torque applied via the handle 5, The displaces bility of the rotation axis or pivot axis 30 in this respect has to be selected so large that a substantially free movahility over the whole stroke of the handle 5 Is made possible. It Is ensured in this manner that no high forces or torques act on lock parts arranged, within the lock 14 even in the end. region of the actuation of the handle S which could result in a destruction of these parts.

If the lock 14 is unlocked again, the adjustment member 44 Is again displaced together with the blocking element 48 into the position shown In Fig, 2, In this respect,, the run-on chamfer 52 runs on at the spigot forming the rotation axis or pivot axis 30 so that said spigot is automatically displaced into the position shown in Fig» 2 in which it is held by the.bounding edge 53, Â further embodiment of the indention Is shown in. a schematic representation In Figs. 6 and 7 with reference to a modified lock 14'.

Fig. 6 shows the unlocked position of the lock 14', with the latchholt 9 being in Its extended position. Instead of the pivot lever 34 in accordance with the: first embodiment* a toothed wheel 58: is provided in the second embodiment which cooperates with the laichbolt 9 via. a. toothed, arrangement 59 formed at the latch holds lower side and not shown, in any more detail in Fig, 6 so that the latchholt 9 Is retracted on a rotation of the toothed, wheel 58 in accordance with: an. arrow 60,

The toothed wheel 58 meshes with a farther toothed wheel 61 which is rotatably supported abou t a rotation axis or pivot, axis 30’. The rotation axis or pivot axis 30’ is In this respect rotatably supported with its free ends In elongate bores 62 which are .formed in the lock cover 16 and in the counter-lock cover, not shown, and which extend substantially perpendicular to the longitudinal extent of an adjustment member 44c At the same time, die rosa don axis or pivot axis 30f is arranged in an elongate hole 63 formed in the adjustment member 444 the elongate hole extending obliquely to the longitudinal alignment of .the adjustment member 44' and obliquely to the elongate holes 62. As can be recognised horn Fig, 6, In tbe shown unlocked position, of the lock 149 the rotation axis or pivot axis 30' is only rotatable about its longitudinal axis, but Is not displaceable in the elongate hole 62 since a longitudinal edge of the elongate hole 63 forms a hounding edge 53' and thus· the adjustment member 44' forms a hounding element 54* lor the rotation axis or pivot axis 309

The further toothed wheel 61 in turn meshes with a toothed wheel 64 which is drivahle, for example, via the handle 5 or via a transmission unit connected to the handle S, for example the drive rod 8 or the control member 36 cornice ted to the drive rod 8 and not shown > in the locked state of the: lock 1:4' shown in Fig, ?, the adjustment member 44* is displaced downwardly in accordance with the arrow 57 so that the blocking element: 48 engages into the region between the rear section 26 of the latehhoit 9 and the rear wall 17 so that a. retraction of the latehhoit: 9 is prevented.

Simultaneously with the displacement of the. adjustment member 44, the rotation axis or pivot axis 30' is displaced Into the position displaced to the left ami shown in Fig 7 by the obliquely arranged elongate hole 68 so that the toothed wheel 61 moves out of engagement: with the toothed wheels 53 and 64. In this locked position In accordance with Fig, 7, the operative connection between the handle 5 or the toothed wheel 64 connected thereto and the latch boll: 9 is interrupted so that a torque applied via the handle S does not act on drive gear elements which are arranged within the lock 14' and which are connected to the blocked latehhoit 9. 1§ΐΜ§ι^.ιβ«ιιΙ.ΙΜ 1 door 2 three-latch lock 3 main lock 4 secondary- locks 5 kandié 6 lalchholt 7 handle nut 8 drive rod 2 latchholts 10 lock cylinder 11 bar exclusions 12 locking bolt 13 latch bar 1.4, 14' lock 15 lock housing 16 lock cover 1.7 rear wall IS guide section 19 guide section 20 arrow 21 section 22 spigot 23 spring element 24 free end of the spring element 25 free end of the spring element 26 rear section 27 contact section 28 engagement section 29 lever arm 30, 30: rotation axis or pivot axis 31 longitudinal slits 32 joint 33 lever arm 34 pivot lever 35; pivot axle 36 control, member 37 coupling section 38 coupling section 39 double arrow 40 elongate hole 41 spigot 42 edge 43 longitudinal side 44, 44'' adjustment member 45 'elongate bole 46 coupling section 47 coupling section 48 blocking element 49 contact section 50 guide section 51 guide element 52 mn~on charnier S3* S3" bounding edge 54, S4" bounding element 55 spigot 56 arrow: 57 arrow 58 toothed wheel 59 toothed arrangement 60 arrow 61 toothed wheel 62 elongate hole: 63 elongate hole 64 toothed wheel
