Definitions

  • the present invention relates to a cylindrical lock operable with a rotatable key, said lock comprising a base body provided with a cylindrical bore, in which bore a set of annular, particularly concentric plates is arranged, said arrangement substantially constituting catchers, said catchers being locked against self-rotation and preferably adapted for engagement with the shank of the rotatable key, with at least one tumbler as well as with guiding means for aligning the catchers in a position enabling the rotatable key to be removed from the lock.
  • An overwhelming majority of the down-to-date cylinder locks with rotatable keys, wherein key actuates lamellar catchers arranged perpendicularly to the former, such as the cylinder lock mentioned in the background section of the patent document US 5,388,438 or the cylinder lock disclosed in the European patent EP 0 989 262 , comprises a base body provided with a cylindrical bore, in which a rotatable cylinder is placed, said cylinder being provided with an entry slot for the tumbler and accommodating a plurality of catchers, the particular arrangements of the latter creating diverse locking combinations, or additional discs enhancing the functionality of the cylinder lock, such as plugs having diverse thicknesses.
  • the additional discs enhancing the functionality of the cylinder lock may serve as lifters, as disclosed in EP 0 989 262 .
  • a considerable problem of such cylinder lock assemblies consists in the difficult delimitation of the deviation tolerances along the longitudinal axis of the assembly, the total deviation tolerance being the sum of the thickness tolerances of the catchers and those of the additional discs, if any, and the length tolerance of the bore of the rotatable cylinder.
  • the deviation tolerances embracing those between the catcher sets with the additional discs, if any, and the rotatable cylinder as well as those between the individual catchers and the individual additional discs, if any are mutually compensated so that the position of the combination tab of each catcher corresponds to the position of the respective combination tab on the rotatable key with the highest degree of accuracy possible.
  • any delimitation of the deviation tolerances provided by inserting shims having diverse thicknesses between the catchers or the additional discs, if any, is accomplished in a statistical or empiric manner since it is not possible to determine the accurate dimensions in any particular point of the assembly in advance.
  • the tabs on the catchers, which correspond to the combination tabs on the rotatable key, are made thinner so that the reduced area of the contact surfaces enables a better compensation of the deviation tolerances to be achieved. Nevertheless, it is not possible to completely eliminate the risk that the corresponding combination tabs on the catcher and on the rotatable key become longitudinally misaligned after the completion of the assembly of the lock due to disparate tolerances and the complete lock will have do be disassembled and readjusted.
  • the prior art further includes various cylinder locks of the above mentioned type involving different solutions for locking the catchers against self-rotation (unintended rotation), the most commonly used technical solution consisting in utilising a friction force between the catchers and shims having diverse thicknesses for retaining the same. Said friction force is induced either by the elimination of the tolerances between the discs by means of variable shims and pressing the discs inside the cavity of the rotatable cylinder against each other as close as possible, which is the case with the cylinder lock according EP 0 989 262 , or by means of additional spring-loaded elements.
  • Another known technical solution is disclosed in GB 2266119 , wherein the discs are subjected to the clamping force induced by a helical spring arranged behind the disc assembly.
  • the objective of the present invention is to eliminate the above disadvantages and drawbacks of the existing technical solutions and to provide a cylinder lock that would enable the thickness tolerances of the catchers and the additional discs, if any, to be compensated in the most simple, accurate and reliable manner possible and that would simultaneously solve the problem relating to the alignment of the catchers and additional discs inside the cylinder lock in order to substantially simplify the process of manufacturing the same.
  • a cylindrical lock operable with a rotatable key said lock comprising a base body provided with a cylindrical bore, in which a set of annular plates constituting at least catchers is arranged axially, said catchers being locked against unintended rotation and adapted for an engagement with a shank of the rotatable key, with at least one tumbler as well as with guiding means for aligning the catchers in a position enabling the rotatable key to be removed from the lock, while according to the invention a plurality of adjacent spacing shims is arranged axially in the cylindrical bore, the spacing shims being locked against relative movement, wherein at least the individually freely rotatable catchers are completely embedded in the spacing shims, which are adapted for engagement with at least one tumbler, with means for locking the catchers against unintended rotation and with means for aligning the same in a position enabling the rotatable key to be removed and the shank of the key to
  • each spacing shim comprises an annular plate provided with an outer contact surface and an internal surface as well as with a discontinuous unilateral rim terminated with a frontal contact surface, wherein the distance between the frontal contact surface and the internal surface exceeding the thickness of the respective catcher, and the unilateral rim is provided with an internal circumferential surface for holding the catcher in its functional position, and with an external circumferential surface for retaining the spacing shim inside the cylindrical bore of the base body, while an axial through bore for inserting the rotatable key is provided in the annular plate.
  • At least one retaining protrusion extends from the frontal contact surface of the unilateral rim of each spacing shim and a shaped recess extending partially in the annular plate is provided in the unilateral rim behind the retaining protrusion.
  • a labyrinth hole for a pair of pair of return rods is arranged opposite to the transversal slot and along the internal circumferential surface of the unilateral rim of each spacing shim, said hole being provided with two opposed guiding edges and with an abutment edge at either end, the edges merging into retaining grooves in the direction towards the internal circumferential surface of the unilateral rim of the spacing shim.
  • the terminating element is formed by a cylindrical body provided with a blind or through axial bore for an insertion of the end portion of the shank of the rotatable key and with at least one interconnecting protrusion and a shaped recess arranged on its frontal side, a peripheral area of the terminating element being further provided with an open-ended cutout for engagement with a pair of return rods, the open-ended cutout being provided with a frontal abutment surface and a bottom surface, which corresponds to a guiding edge arranged on the spacing shim proximally to the centreline of the same, and which is terminated with end recesses, while - in the opposite position with respect to the open-ended cutout - the peripheral portion of the terminating element is further provided with a longitudinal slot matching with a transversal slot of the spacing shim, and with a transversal notch engaging with an arresting latch.
  • the most significant advantage of the cylinder lock according to the invention consists in that the total deviation tolerance of the locking system is composed merely of the sum of the deviation tolerances of the outer thicknesses T3 of the spacing shims.
  • the thickness tolerances of the catchers are compensated in that the dimensions of the catchers are included in the functional widths T1 of the spacing shims, i.e. between the frontal contact surface and the internal surface of the individual spacing shims.
  • the above surfaces partly keep the catcher in a relatively stable position and partly enable the catcher to be displaced within a small axial range, which displacement compensates any possible deviation between the positions of the coding tab of the catcher and that of the rotatable key during the insertion of the key.
  • the solution according to the invention further enables the relatively long thin-walled rotatable cylinder, which is one of the parts that must be unavoidably manufactured by machining, to be replaced with a series of spacing shims, each being producible using a more effective manufacturing method, such as stamping or precise casting.
  • the solution according to the invention also enables the return rods, when the latter are included in the mechanism, to be guided in a relatively precise manner, namely by means of enclosed grooves formed in the spacing shims and the catchers to be more securely locked against self-rotation by means of the return bars, said bars being held in the locking positions by the relatively precise shaped edges of the above mentioned enclosed grooves.

  • the cylinder lock according to the invention comprises a base body 1 ( Fig. 1 ) provided with a cylindrical bore 2 , in which a series of spacing shims 3 is arranged, in which arrangement standard individual freely rotatable catchers 4 and lifters 5 are embedded.
  • the first of the catchers 4 in the series shown is the one which is not embedded in the spacing shim 3 , since it is possible to arrange the first catcher inside the internal space of a cylindrical collar 6 so that only the subsequent catcher 4 is placed in the first spacing shim 3 .
  • the outer catchers 4 or lifters 5 may also be arranged outside the spacing shim 3.
  • the catchers 4 are provided with standard open-ended notches 7 having rounded bottom portions and outer edges 8 , 9 .

  • Fig. 1 shows only one of the grooves 34 .
  • the series of spacing shims 3 is adjoined by a terminating element 35 provided with a pair of compression springs 36 and with an arresting latch 37 .
  • the terminating element 35 accommodates a carrier 38 , which simultaneously engages with a finger 39 for controlling an adjoining mechanism (not shown) of the cylinder lock.

  • each of the spacing shims 3 is provided with an annular plate 69 having an outer contact surface 43 and an inner surface 42.
  • a part of the peripheral area of the spacing shim 3 is provided with a discontinuous unilateral rim 70 concluded with a frontal contact surface 41 , wherein the distance between the frontal contact surface 41 and the internal surface 42 equals the inner functional width T1 of the spacing shim 3 .
  • Said inner functional width T1 always exceeds the thickness T2 ( Fig. 3 ) of the respective insertion element, i.e. the catcher 4 , or that of the lifter 5 , if any.
  • Each of the spacing shims 3 is further provided with an opposite contact surface 43 ( Fig.
  • the discontinuous unilateral rim 70 of each of the spacing shims 3 is further provided with an internal circumferential surface 44 for holding the respective catcher 4 in its functional position as well as with an external functional surface 45 for retaining the respective spacing shim 3 inside the cylindrical bore 2 of the base body 1 of the cylinder lock ( Fig. 1 ).
  • each of the spacing shims 3 is further provided with an axial bore 46 , which may be circular in shape, for inserting a rotatable key (not shown) and with a transversal slot 47 arranged in the circumferential portion and adapted for guiding the standard tumbler 29 ( Fig. 1 , 4, 5 ).

  • the labyrinth hole 48 is provided with two opposed guiding edges 49 , 50 and with two abutment edges 51 , 52 at either end, the latter merging into retaining grooves 53 , 54 in the direction towards the internal circumferential surface of the spacing shim 3 .
  • Each of the spacing shims 3 is provided with at least one retaining protrusion 55 extending from the frontal contact surface 41 of the unilateral rim 70 , wherein the shaped recess 56 is formed in the unilateral rim 70 behind the retaining protrusion 55 and it extends partially in the annular plate 69 of the spacing shim 3 .

  • Each of the retaining protrusions 55 of the respective spacing shim 3 extends into the shaped recess 56 of the adjacent spacing shim 3 within the assembly of the cylinder lock. Thus the adjoining spacing shims 3 are locked against relative rotational movements.
  • the terminating element 35 which has the shape of a relatively low cylinder, is provided with at least one element enabling a non-rotational interconnection with the last spacing shim 3 .
  • the terminating element 35 ( Figs. 6, 7, 8 ) is provided with two interconnecting projections 57 and four shaped recesses 58 .
  • the terminating element 35 is further provided with an, at least blind, axial bore for the insertion of the end portion of the shank of the rotatable key (not shown).
  • the terminating element 35 is provided with a through bore 59 adjoining to the axial bores 46 of the spacing shims 3 .
  • the terminating element 35 is provided with an open-ended cut-out 60 for the insertion of the standard return bars 13 .
  • a frontal abutment surface 61 of the open-ended cut-out 60 delimits the end positions of the return bars 13 and the bottom surface 62 along with end recesses 63 , 64 of the open-ended cut-out 60 are intended for guiding the return bars 13 during their functional movements.
  • the terminating element 35 is further provided with a longitudinal slot 65 having the same purpose as the transversal slots 47 of the spacing shims 3 , namely to enable an insertion of the tumbler 29 .
  • the opposite side of the terminating element 35 may be adapted for an interconnection with various adjoining parts (not shown).
  • the terminating element 35 is provided with a segmented collar 66 for the shape-based connection with the carrier 38 and for retaining the disc spring 40 slipped over the same.
  • the terminating element 35 is further provided with a transversal notch 67 created therein in a known manner and serving for the insertion of the compression springs 36 and the arresting latch 37 , the latter engaging with a corresponding cut-out (not shown) created in the base body 1 .
  • the design and the functions of the compression springs 36 and the arresting latch 37 are analogous to the embodiments known in the art, which means that the above parts serve to retain the set of the spacing shims 3 and to lock it against rotation during the alignment of the catchers 4 enabling the latter to assume the positions that are necessary for the insertion of the shank of the rotatable key.
  • the spacing shims 3 may also be provided with special means enabling the interconnection with the terminating element 35 .
  • the above means are formed by the transversal notch 24 for the insertion of the interconnecting projection 57 of the terminating element 35 and by the retaining protrusion 55 that engages with the shaped recess 58 of the terminating element 35 .
  • the cylindrical bore 2 of the base body 1 of the cylinder lock is provided with a longitudinal notch 68 formed therein ( Fig. 3 ), into which the tumbler 29 partially extends.
  • the above mentioned standard pair of return bars 13 acts as usual means for transferring the torque from the lifters 5 to the spacing shims 3 , as a means for returning the catchers 4 into the positions enabling the rotatable key to be removed and as a means for preventing any unintended rotation of the catchers 4 , since in the idle condition of the cylinder lock each of the return bars 13 is pushed by the guiding edges 49 of the labyrinth holes 48 into one of the recesses 11 , 12 of the respective lifter 5 and simultaneously abuts against one of the outer edges 8 , 9 of the open-ended notches 7 formed in the catchers 4 .
  • the return bars 13 are held in the recesses 11 , 12 in that the rounded bottom surfaces of the open-ended notches 10 formed in the lifters 5 extend into the space between the guiding edges 49 , 50 of the labyrinth holes 48 , thus preventing the return bars 13 from protruding into the same space.
  • the rotation of the rotatable key causes the cylinder lock to be locked or unlocked in a completely known manner.
  • the coding projections (not shown) formed on the shank of the rotatable key come into contact with the coding tabs (also not shown) formed in the catchers 4 . Since the catchers 4 are arranged inside the corresponding spacing shims 3 with a certain amount of clearance and, at the same time, very precisely longitudinally aligned with respect to the shank of the rotatable key, the coding projections on the shank very precisely engage with the coding tabs in the catchers 4 , driving the latter successively in rotation.
  • the lifters 5 are also successively driven in rotation.
  • the lifters 5 cause one of the return bars 13 to move in a well known manner.
  • the return bar 13 is guided by the guiding edges 49 , 50 of the labyrinth holes 48 formed in the spacing shims 3 , said guiding action preventing the return bar from touching the rounded bottom portions of the open-ended notches 7 formed in the catchers 4 .
  • the lifters 5 displace the driven return bar 13 up to the respective abutment edge 51 , 52 of the labyrinth hole 48 , where that driven return bar 13 strikes against the other return bar 13 (not shown), forcing the same into one of the respective retaining grooves 53 , 54 formed in the corresponding labyrinth holes 48 .
  • the engagement of the return bars 13 with the respective abutment edge 51 , 52 cause the spacing shims 3 to rotate.
  • the rotation of the spacing shims 3 pushes the tumbler 29 out from the longitudinal notch 68 of the base body 1 .
  • tumbler 29 After having been displaced from the longitudinal notch 68 of the base body 1 , the tumbler 29 enters farther into the transversal slots 47 formed in the spacing shims 3 and into the longitudinal slot 65 formed in the terminating element 35 . At the same time, tumbler 29 enters into the slots formed in the catchers 4 and lifters 5 that have been adjusted against the former by means of the movement of the rotatable key. This enables the entire internal arrangement of the cylinder lock to be driven in rotation and all the necessary operations to be accomplished.
  • the respective return bar 13 and the tumbler 29 act as driving means causing those parts to rotate which are not in direct contact with the rotatable key, such parts particularly including the spacing shims 3 and also the terminating element 35 .
  • the additional driving means comprise the coupled retaining protrusions 55 and the shaped recesses 56 of the spacing shims 3 along with the means for interconnecting the last spacing shim 3 and the terminating element 35 .
  • the cylindrical collar 6 is locked by the adjoining spacing shim 3 .
  • the cylindrical collar 6 is driven in the direction of rotation in a known manner, namely by the projection 33 formed on the frontal face of the adjusting cylinder 15 and also by means of the pair of return bars 13 .
  • the tumbler 29 is pushed out of the slots formed in the catchers 4 and, also in a known manner, inserted back into the longitudinal notch 68 formed in the base body 1 . This is accomplished by means of the inclined walls of the slots formed in the lifters 5 to facilitate the insertion of the tumbler 29 .
  • the removal of the rotatable key is enabled in that the catchers 4 are aligned, again in the known manner.
  • the key is turned to the position which enables the tumbler 29 to be aligned with the longitudinal notch 68 of the base body 1 and the arresting latch 37 to engage with the corresponding cut-out (not shown) formed in the base body 1 , causing the terminating element 35 and hence also the spacing shims 3 to be locked against rotation.
  • the rotatable key is turned in the opposite direction into such angular position that enables the catchers 4 to be aligned under the action of the return bars 13 so that the openings of the latter stop preventing the rotatable key from being removed from the lock.
  • the technical solution according to the invention may be utilized for designing and manufacturing cylinder locks with rotatable keys, particularly when a more sophisticated and accurate design and more cost-effective production are required.
