Definitions
- the present invention relates to a lock cylinder which can be assembled from several units.
- Lock cylinders of this type are known from DE 37 38 832 A1, the lock cylinder being assembled from a central and two terminal units. If greater lengths of lock cylinder are required, interposed extension units can optionally be provided.
- the terminal units have, in the flange which is orientated radially to the lock cylinder core region supporting the cylinder core, two terminally admitted, superimposed pins which engage in the flange of the central piece and are fixed there by a transverse pin. If an extension unit is interposed, these pins pass through corresponding openings in the extension unit. Because of this, it is not possible to fit profile lock cylinders on this design with normal pin tumblers. Cylinder cores with a central projecting band which rest, on the one hand, in the terminal units and, on the other hand, in the central unit are also used in this design.
- Lock cylinders of this type are also known from US patent No 3 293 892, which describes and claims a lock assembly comprising first and second housings, a cam driver in each said housing, the driver of said first housing including a lock plug, a latch operator cam rotatably mounted between said housings, a spacer ferrule interposed between said cam and said second housing, said ferrule having an inner bore, a support bar fixed to said housings and maintaining said housings in abutting relation, respectively, with said cam and said ferrule, a pair of independently rotatable abutting link means for connecting said cam drivers selectively and alternatively to said cam, one said link means being longitudinally extensible, and including at least two relatively longitudinally movable cylindrical segments rotatably mounted in said ferrule, one said segment including a drive portion slidably extending from one segment to the other segment and locking said segments against relative rotation, each said link means having at its inner end a generally cylindrical wafer member, said wafer members being relatively rotatable and disposed in end
- the invention provides a lock cylinder, which can be assembled from several units, with a locking member arranged in the central region and at least one locking mechanism adjacent thereto, said locking mechanism consisting of a cylinder core which comprises a key channel and to which tumblers are allocated, characterised by a fit and turn connection in the form of a bayonet connection between a unit allocated to the locking member and the unit containing the locking mechanism, said connection locking the two units against longitudinal movement.
- a very wide variety of overall lengths can be provided by means of units which are of different lengths and contain the locking mechanisms and units of different lengths equipped with the locking member.
- the components for the locking mechanism as well as coupling and locking member of the respective units can always be identical in design. Different lengths are then only bridged over by suitable spacer members. However, these do not adversely affect the production of the fit and turn connection.
- the bayonet connection is achieved by an annular band, located concentrically to the cylinder core axis, on one unit, which engages in a groove in the adjacent unit, mutual hooking of the two elements being achieved in the region of a lock cylinder housing flange. When two adjacent units are fitted together, therefore, the annular band of one unit engages initially in the groove in the adjacent unit.
- This position is secured by mutual pivoting of the two units, so that the housing flanges come into alignment with one another with simultaneous mutual hooking of these units.
- the hooking between the adjacent units can be adjusted so that the space for pin tumblers of normal design is not reduced. Pin tumblers can therefore be used and consequently give the lock cylinder high security.
- This bayonet connection even allows the lock cylinder to receive a certain orientation from one end to the other should the insertion opening in a door not be worked exactly. This case can arise, in particular, with thick doors of the type used, for example, for deep freeze room doors, owing to the relatively thickly dimensioned doors.
- the lock cylinder can easily be inserted. Finishing of the fitting opening, if it is not produced exactly, does not therefore have to be carried out.
- the lock cylinder 1 designed as a profile double cylinder is assembled from a central unit 3 containing a locking member 2 and the two adjacent units 4 comprising the locking mechanisms W.
- the two units 4 are of equal length and are identical in design.
- the cylinder housing G formed by the units 3, 4 has a circular cylindrical portion A and a housing flange B oriented radially thereto, the housing flanges of mutually adjacent units being aligned with one another when the lock cylinder is assembled.
- a cylinder core 6 is mounted in a central bore 5 of the circular cylindrical portion A of each unit 4.
- the cylinder core 6 has, at the height of the cylinder core axis, a key channel 7 the longitudinal plane of which is perpendicular to the housing flange B.
- the cross-sectional profile of the key 8 is adapted to that of the key channel 7.
- Pin bores 9 of the cylinder core 6 correspond to the key channel 7, these pin bores 9 being aligned with pin bores 10 of the housing flange B.
- Two rows of pin bores 9, 10 are provided in a parallel arrangement such that in each case the bores of one row alternate with the bores of the other row.
- the pin bores 9, 10 receive pin tumblers 13 consisting of core pins 11 and housing pins 12 which are in turn loaded in the direction of the key channel 7 by pin springs 14.
- a non-rotatable arrangement of the pin tumblers 13 is produced owing to the suitable cross-sectional shape of the pin bores 9, 10 and the pin tumblers 13 guided therein.
- the ends of the pin tumblers 13 penetrating into the key channel 7 are flattened and are located by indentations (not shown) provided on the broad sides of the flat key 8 such that the separating line of the core pins 11 and the housing pins 12 comes to rest at the height of the rotational joint of the cylinder core so that the cylinder core can be rotated by means of the key.
- the pin tumblers 13 form the locking mechanism W in conjunction with the pin springs 14 and the cylinder core 6.
- the axial position of the cylinder core 6 is secured, on the one hand, by a frontal band 15 of increased cross section and, on the other hand, by a spring washer 16 which dips, at the internally located end of the cylinder core 6, into an annular groove 17.
- the unit 4 is equipped with a slot 18 which extends into the housing flange B.
- the end of the cylinder core 6 located within the housing has two successive bore portions 19, 20.
- the bore portion 19 of smaller diameter issues from the internal front edge of the cylinder core 6.
- the front end of the cylinder core 6 is equipped with a transverse slot 21 the length of which extends transversely to the key channel 7.
- the internally located front end of the cylinder core 6 extends inside the unit 4 in the bore 5 thereof.
- the unit 4 containing the locking mechanism W has an annular band 22 arranged concentrically with the axis of the cylinder core. This is achieved by appropriate turning at the inner end of the unit.
- a cavity 23 is also worked in at the height of the transverse slot 18.
- the base 23' of the cavity extends concentrically with the axis of the cylinder core.
- a hook-type projection 24 is attached to the cavity 23. Its hook head 24' is also orientated concentrically with the axis of the cylinder core.
- the unit 3 equipped with the locking member 2 is provided centrally with a locking member recess 25 extending into the housing flange B, two cross pieces 26 of equal thickness, which extend parallel to one another, being formed.
- Niches 27 are formed in the region of the housing portion B on both sides of the cross pieces 26. Their base 27' is oriented concentrically with the cylinder core axis.
- the niches 27 are followed by hook-shaped projections 28 which point toward the cylinder core axis, the hook heads 28' of which also have the corresponding concentric course.
- the niches 27 serve to receive the hook-shaped projections 24 of the units 4 while the projections 28 of the central unit 4 extend into the cavities 23 thereof, producing a continuous face on the lock cylinder housing.
- a threaded bore 29 for the admission of a lock cylinder fastening screw is located beneath the locking member recesses 25 centrally in the housing flange B of the unit 3.

- Spacer members 32 rest in the bores 31.
- the spacer members 32 are similar in construction to the internal ends of the cylinder cores 6. They have bore portions 33, 34 which, in turn, are arranged such that the one 33 of smaller diameter issues from the internal face end of the spacer member 32.
- the spacer member 32 is equipped there with a transverse slot 35 for the engagement of diametrally opposed coupling projections 36 of a cylindrical coupling piece 37. Such coupling projections 36 are provided in an aligned arrangement at both ends thereof.
- the coupling member 37 rests movably in the hub central wall 38 of a locking member hub 39 of the locking member 2.
- the locking member 2 is entrained by a transverse pin 40 in the hub central wall which penetrates a longitudinal slot 41 of the coupling piece 37.

It will be appreciated that the extension units also require spacer members which produce the connection to the cylinder cores 6 and co-operate with the spacer members on the coupling piece side. Displacement pegs of corresponding length should also be provided.

Description
- The present invention relates to a lock cylinder which can be assembled from several units.
- Lock cylinders of this type are known from
DE 37 38 832 A1, the lock cylinder being assembled from a central and two terminal units. If greater lengths of lock cylinder are required, interposed extension units can optionally be provided. The terminal units have, in the flange which is orientated radially to the lock cylinder core region supporting the cylinder core, two terminally admitted, superimposed pins which engage in the flange of the central piece and are fixed there by a transverse pin. If an extension unit is interposed, these pins pass through corresponding openings in the extension unit. Because of this, it is not possible to fit profile lock cylinders on this design with normal pin tumblers. Cylinder cores with a central projecting band which rest, on the one hand, in the terminal units and, on the other hand, in the central unit are also used in this design. - Lock cylinders of this type are also known from US
patent No 3 293 892, which describes and claims a lock assembly comprising first and second housings, a cam driver in each said housing, the driver of said first housing including a lock plug, a latch operator cam rotatably mounted between said housings, a spacer ferrule interposed between said cam and said second housing, said ferrule having an inner bore, a support bar fixed to said housings and maintaining said housings in abutting relation, respectively, with said cam and said ferrule, a pair of independently rotatable abutting link means for connecting said cam drivers selectively and alternatively to said cam, one said link means being longitudinally extensible, and including at least two relatively longitudinally movable cylindrical segments rotatably mounted in said ferrule, one said segment including a drive portion slidably extending from one segment to the other segment and locking said segments against relative rotation, each said link means having at its inner end a generally cylindrical wafer member, said wafer members being relatively rotatable and disposed in end-to-end abutting position, each said wafer member including a radially extending drive portion, a complemental drive portion on said cam adjacent said drive portions of said wafers, said wafers being axially reciprocable with respect to said cam to engage one only of said wafers in driving connection with said cam, spring means interposed between said second housing and said one link means for biasing said one link means toward said cam, normally to engage the wafer of said one link means with said cam, and clear the wafer member of said other link means from said cam, said other link means including portions positioned to be engaged and inwardly shifted by a key inserted into said plug, thereby to connect said wafer of said other link means with said cam and clear said wafer of said one link means therefrom. - It is an object of the present invention to design a lock cylinder of this type such that, in addition to simple construction of the units, the units can be assembled quickly with easy handling to form a lock cylinder of suitable overall length.
- The invention provides a lock cylinder, which can be assembled from several units, with a locking member arranged in the central region and at least one locking mechanism adjacent thereto, said locking mechanism consisting of a cylinder core which comprises a key channel and to which tumblers are allocated, characterised by a fit and turn connection in the form of a bayonet connection between a unit allocated to the locking member and the unit containing the locking mechanism, said connection locking the two units against longitudinal movement.
- This design results in a lock cylinder, the units of which can be combined extremely simply to form a lock cylinder having the desired overall length. The units are divided up such that one of them contains the locking member and the other the locking mechanism. The combination of these units requires only a fitting together process and subsequent twisting to produce the lock cylinder straightaway. Assembly does not require any great practical skill either and can be carried out quickly. It can even be undertaken simply by unskilled laymen. Production of the bayonet connection produces a sturdy lock cylinder, the housing of which can absorb large axial forces. If a double lock cylinder is to be provided, it will be appreciated that the unit comprising the locking member is allocated a respective locking mechanism which is adjacent on both sides in the path of the bayonet connection. A very wide variety of overall lengths can be provided by means of units which are of different lengths and contain the locking mechanisms and units of different lengths equipped with the locking member. The components for the locking mechanism as well as coupling and locking member of the respective units can always be identical in design. Different lengths are then only bridged over by suitable spacer members. However, these do not adversely affect the production of the fit and turn connection. In particular, the bayonet connection is achieved by an annular band, located concentrically to the cylinder core axis, on one unit, which engages in a groove in the adjacent unit, mutual hooking of the two elements being achieved in the region of a lock cylinder housing flange. When two adjacent units are fitted together, therefore, the annular band of one unit engages initially in the groove in the adjacent unit. This position is secured by mutual pivoting of the two units, so that the housing flanges come into alignment with one another with simultaneous mutual hooking of these units. The hooking between the adjacent units can be adjusted so that the space for pin tumblers of normal design is not reduced. Pin tumblers can therefore be used and consequently give the lock cylinder high security. This bayonet connection even allows the lock cylinder to receive a certain orientation from one end to the other should the insertion opening in a door not be worked exactly. This case can arise, in particular, with thick doors of the type used, for example, for deep freeze room doors, owing to the relatively thickly dimensioned doors. However, the lock cylinder can easily be inserted. Finishing of the fitting opening, if it is not produced exactly, does not therefore have to be carried out. It is therefore possible to fix the units in their prescribed position. This can be carried out using a transverse screw which is provided in the hooking region. Further variations for achieving different overall lengths are thus possible by providing a tumbler-free extension unit which is also introduced by a bayonet connection between adjacent units. These extension units can be of different lengths or, alternatively, a plurality of such extension units can be inserted. Along with the introduction of extension units, spacer sleeves which form the extension of the cylinder core and serve to control the coupling can also be inserted. It is thus possible to form a stop for the axially aligned rotational end position of the flanges of adjacent units so that the prescribed orientation exists when the stop is reached when producing the bayonet connection.

- Figure 14 shows, also in elevation and partly in section, a cylinder housing of increased overall length resulting from the insertion of units, dimensioned to suitable lengths, including extension units.
- According to Figures 1 and 10, the
lock cylinder 1 designed as a profile double cylinder is assembled from acentral unit 3 containing alocking member 2 and the twoadjacent units 4 comprising the locking mechanisms W. The twounits 4 are of equal length and are identical in design. - The cylinder housing G formed by the
units - A
cylinder core 6 is mounted in acentral bore 5 of the circular cylindrical portion A of eachunit 4. Thecylinder core 6 has, at the height of the cylinder core axis, akey channel 7 the longitudinal plane of which is perpendicular to the housing flange B. The cross-sectional profile of thekey 8 is adapted to that of thekey channel 7.Pin bores 9 of thecylinder core 6 correspond to thekey channel 7, thesepin bores 9 being aligned withpin bores 10 of the housing flange B. Two rows ofpin bores pin tumblers 13 consisting ofcore pins 11 andhousing pins 12 which are in turn loaded in the direction of thekey channel 7 bypin springs 14. A non-rotatable arrangement of thepin tumblers 13 is produced owing to the suitable cross-sectional shape of thepin bores pin tumblers 13 guided therein. The ends of thepin tumblers 13 penetrating into thekey channel 7 are flattened and are located by indentations (not shown) provided on the broad sides of theflat key 8 such that the separating line of thecore pins 11 and thehousing pins 12 comes to rest at the height of the rotational joint of the cylinder core so that the cylinder core can be rotated by means of the key. - The
pin tumblers 13 form the locking mechanism W in conjunction with thepin springs 14 and thecylinder core 6. - The axial position of the
cylinder core 6 is secured, on the one hand, by afrontal band 15 of increased cross section and, on the other hand, by aspring washer 16 which dips, at the internally located end of thecylinder core 6, into anannular groove 17. For receiving thespring washer 16, theunit 4 is equipped with aslot 18 which extends into the housing flange B. - The end of the
cylinder core 6 located within the housing has twosuccessive bore portions bore portion 19 of smaller diameter issues from the internal front edge of thecylinder core 6. At the height of thebore portion 19, the front end of thecylinder core 6 is equipped with atransverse slot 21 the length of which extends transversely to thekey channel 7. The internally located front end of thecylinder core 6 extends inside theunit 4 in thebore 5 thereof. - At the internally located end, the
unit 4 containing the locking mechanism W has anannular band 22 arranged concentrically with the axis of the cylinder core. This is achieved by appropriate turning at the inner end of the unit. Acavity 23 is also worked in at the height of thetransverse slot 18. The base 23' of the cavity extends concentrically with the axis of the cylinder core. A hook-type projection 24 is attached to thecavity 23. Its hook head 24' is also orientated concentrically with the axis of the cylinder core. - The
unit 3 equipped with the lockingmember 2 is provided centrally with a lockingmember recess 25 extending into the housing flange B, twocross pieces 26 of equal thickness, which extend parallel to one another, being formed.Niches 27 are formed in the region of the housing portion B on both sides of thecross pieces 26. Their base 27' is oriented concentrically with the cylinder core axis. Theniches 27 are followed by hook-shapedprojections 28 which point toward the cylinder core axis, the hook heads 28' of which also have the corresponding concentric course. Theniches 27 serve to receive the hook-shapedprojections 24 of theunits 4 while theprojections 28 of thecentral unit 4 extend into thecavities 23 thereof, producing a continuous face on the lock cylinder housing. - A threaded bore 29 for the admission of a lock cylinder fastening screw is located beneath the locking member recesses 25 centrally in the housing flange B of the
unit 3. -
Annular grooves 30 into which theannular bands 22 of thelocking mechanism units 4 extend are worked from the external end faces of thecross pieces 26. Theannular grooves 30 are followed bybores 31, the diameter of which corresponds to thebores 5.Spacer members 32 rest in thebores 31. Thespacer members 32 are similar in construction to the internal ends of thecylinder cores 6. They havebore portions spacer member 32. Thespacer member 32 is equipped there with atransverse slot 35 for the engagement of diametrally opposedcoupling projections 36 of acylindrical coupling piece 37.Such coupling projections 36 are provided in an aligned arrangement at both ends thereof. Thecoupling member 37 rests movably in the hubcentral wall 38 of a lockingmember hub 39 of the lockingmember 2. The lockingmember 2 is entrained by atransverse pin 40 in the hub central wall which penetrates alongitudinal slot 41 of thecoupling piece 37. Thespacer members 32 which, in turn, are fastened byspring washers 42 so as to be axially unmovable extend to the central wall of the hub. For this purpose, thespring washers 42 engage in annular grooves 43 of thespacer members 32. To allow thespacer members 32 to be entrained by thecylinder cores 6, entrainingprojections 44 issue from the front edges of the spacer members facing the cylinder cores and, in turn, project into thetransverse slot 21 of thecylinder cores 6. - A bore 45 is also provided centrally in the
spacer member 32, to receive adisplacement peg 46 which is controlled by the key tip 8' such that it displaces thecoupling piece 32 during insertion of the key 8 such that the opposingcoupling projections 36 enter thebore portion 34 of greater cross section of thecorresponding spacer member 32 and do not impair rotation of the cylinder core receiving the key. - The
individual units adjacent units annular band 22 dips into theannular groove 30. The position according to Figure 9 then exists. Theunits projections 44 of thespacer member 32 project into the transverse slot of thecylinder core 6. Figure 3 shows that the rotational end position of the fit and turn connection is secured by atransverse screw 47. The receiving bore for thetransverse screw 47 is located in thecentral unit 3 and is orientated such that when thetransverse screw 47 is turned in, it presses with its inner end on the hook-shapedprojection 24 of theunit 4. - The fact that the axially aligned rotational end position is reached by a stop is not illustrated. After loading thereof, the prescribed orientation always exists after twisting of the units.
- Figure 11 illustrates a cylinder housing G' of relatively great length. This is a result of the fact that, on the one hand, the two locking mechanism units 4' have a somewhat greater length than the
units 4. Furthermore, the locking member unit 3' is also longer. This Figure shows that the cross pieces 26' have a greater width. Spacer members of greater length should be used according to these extensions. The cylinder cores would also have to be lengthened in design. The displacement pegs should also be correspondingly long in size. - The cylinder housing G'' shown in Figure 12 has an even greater length. In addition to the structure illustrated in Figure 11, a
further extension unit 48 is inserted between one locking mechanism unit 4' and the locking member unit 3'. Thisextension unit 48 also has, on opposing end faces,projections - The overall length of the cylinder housing G''' in Figure 13 is similar to that of the cylinder housing G'' illustrated in Figure 12. Only the assembly of the units varies.
Locking mechanism units 4, 4' are selected as well as twoextension units 48. The locking member unit 3'' in which crosspieces 26, 26' of different width are found is modified. - The greater length of the cylinder housing G'''' illustrated in Figure 14 is achieved by the use of two locking mechanism units 4', two
extension units 48 and one locking member unit 3'. It will be appreciated that the extension units also require spacer members which produce the connection to thecylinder cores 6 and co-operate with the spacer members on the coupling piece side. Displacement pegs of corresponding length should also be provided. - It is quite possible to produce a cylinder length of 300 mm by assembling a lock cylinder from various units.
Claims (6)
