Definitions

  • This invention is concerned with a coupling mechanism for a double cylinder lock of the type which comprises a coupling element extending between the inner end faces of the two cylinder cores.
  • Such a coupling mechanism is known from the DE-PS 2,133,782, in which a central spindle of the same material extends from one coupling body.
  • the one coupling body is provided at its end with diametrically opposed projections, whilst the other coupling body has a bore provided with appropriate slots in order to be able to combine the two coupling bodies by way of a bayonet assembly. If a key is inserted on one side of the double cylinder lock and it is turned then it is impossible for the cylinder to be locked from the other side of the cylinder lock.
  • This construction also does not allow the use of emergency keys, which have for example longitudinally-extending slots for arranging the tumblers.
  • the tumblers could be arranged and the cylinder core be turned afterwards by means of such an emergency key.
  • displacement of the coupling element is not possible, even if the cylinder cores align with one another.
  • the emergency key is not in fact able to displace the coupling body facing it so that its flanks can engage with the boss of the locking member.
  • the object of the present invention is to provide a coupling mechanism for a double cylinder lock of the type described which can be used in different ways while maintaining its design and structure and in which engagement by the point of the key is avoided.
  • the present invention provides a coupling mechanism for a double cylinder lock comprising a coupling element extending between the inner faces of the two cylinder cores in the form of two coupling bodies mounted on a central spindle having flanks projecting from the surface, the end sections of which facing away from each other are in positive engagement with the adjacent cylinder cores for transferring the rotary motion of the cylinder core to the locking member boss, which surrounds the coupling element and has at least one coupling engagement aperture characterised in that the flanks of the coupling bodies are movable into the discs spring loaded against one another, the periphery of which are of the same shape as the coupling engagement aperture and which discs are disposed to be displaceable in relation to the centre wall of the boss.
  • the coupling mechanism is designed as a so-called emergency coupling, then this can be achieved by designing the discs to have such a thickness, that there is no longer any displacement of the discs by the key.
  • the appropriate emergency key then has to be provided with longitudinal slots, so that the emergency throw is equal to at least half of the thickness of the centre wall of the boss. It is, however, also possible to make the discs of such a thickness, that there is still a certain movement of the discs towards one another.
  • the slots for the emergency key then do not need be designed to be quite so long. They can thus be shorter than half of the thickness of the centre wall of the boss.
  • the coupling element does not have to be taken along by the key tip.
  • the coupling mechanism can be used in cylinder locks, in which the keys have slots on their narrow edge or on their broadside. Apart from that, the boss of the locking member is secured against twisting, even if there is no key in the lock.
  • the cylinder core ends facing each other do not need to be altered for the coupling mechanism to be used as a standard coupling, emergency coupling or a coupling lockable on both sides.
  • the plan form of the discs in compliance with the rectangular shape, is designed so that two opposite narrow edges extend convexly.
  • the two supporting means provided in opposite corner areas are sufficient to ensure that tilting which would affect the displacement cannot occur, if the key tip acts off-centre on the coupling element.
  • the end sections of the steel needles may be a stop collar at one end and a circular spring clip at the other end. Furthermore, the enlargements can be formed when the steel needle is severed. The cup-shaped recesses then provide an engagement area for the appropriate severing tool. By not riveting the end sections the steel needle itself is not subjected to any kind of deformation which might affect the seating of the coupling bodies, so that maximum mobility of the coupling bodies is constantly ensured despite some tolerance. Advantages from the point of view of assembly technology are obtained by providing stops on the inner side of the boss for the deflection of the discs. This permits installation of the locking member boss into the coupling mechanism as a prefabricated constructional unit.
  • the stops are formed by circlips inserted into annular grooves of the locking member boss.
  • One circlip will generally be sufficient, provided that a fixed stop is provided.
  • this can also be attained by a centre disc arranged between the discs. The two outer discs can then remain unaltered. This centre disc does not however affect the deflection of the two outer discs towards one another.
  • the deflection property of the discs and the spring loading of the coupling bodies towards each other can be induced by a common flat spring, which can be made economically by die cutting.
  • the flat springs produced have at their edge, deflected tongues for abutting against the discs and, occupying a middle position, deflected flaps for resting against the coupling bodies.
  • the deflection has to be such that the tongues and flaps are pointing in opposite directions to one another to result in a uniform abutment.
  • its plan form is comparable with that of a disc.
  • the coupling bodies are here to be additionally supported by springloading against each other.
  • the double cylinder lock is designed to be the same for all coupling mechanisms. It comprises a housing 1 having a central cut-out 2, though which the two housing half-members 3 and 4 are formed. In the areas of the housing half-members 3, 4 of larger cross-section, are rotatably mounted the two cylinder cores 5, 6 which are axially aligned with each other and are of equal size.
  • a locking member boss 8 bearing a locking ward 7 extends in the cut-out.
  • a coupling mechanism 9 is assigned to the locking member boss according to the first exemplary embodiment illustrated in Figures 1 to 8 in order to be able to couple the cylinder plugs 5, 6 to the locking member boss 8.
  • the circlips 11 known per se on both sides of the locking member boss 8 are used to ensure axial locking in position of the cylinder plugs 5, 6 in the housing half-members 3 or 4.
  • the double cylinder lock comprises a row of pin tumblers in each housing half member 3, 4.
  • Each pin tumbler is made up of a core pin 12 and a housing pin 13, which are guided in corresponding location holes of the cylinder core and housing.
  • the housing pins 12 are impinged by respective pin springs 14 (sic F) in the direction of the cylinder core.
  • the pin tumblers are then displaced so that the separating line T between the core pins and the housing pins does not lie on the sliding line of the cylinder cores.
  • the cylinder cores are thus prevented from turning.
  • a key 14 illustrated in Figure 1 which penetrates a vertically oriented keyway 15 of the cylinder plug 5
  • the pin tumblers are aligned so that the separating line T between the housing pins and core pins lies at the level of the sliding joint of the cylinder core thus allowing the latter to be turned.
  • the centre wall 10 of the boss is provided centrally with a coupling engagement aperture 16, in which two discs 17, 18 which are spring biased towards each other are displaceably fitted.
  • the plan form of the discs and accordingly also the coupling engagement aperture 16 are designed in a rectangular shape 50 that two opposite narrow edges 17′, 18′ extend convexly towards each other. The respective narrow edges are in alignment with the circumference of the cylinder plugs 5, 6.
  • four single compression springs 19 which are seated in the corner areas of the discs 17, 18 are provided. Their end coils are resting in diameter-conforming countersunk holes 20 of the discs 17, 18.
  • the single compression springs 19 and countersunk holes are dimensioned so that the discs 17, 18 are able flatly to abut each other.
  • the inner side of the boss is provided with stops for the deflection of the discs. These are formed on the embodiment according to the example by circlips 22 inserted into annular grooves 21 of the locking member boss 8. In the position of the discs 17, 18 restricted by the stop, their outer end faces are thus flush with the corresponding end faces of the centre wall 10 of the boss.
  • the coupling mechanism 9 comprises a coupling element 23 assigned to the locking member boss 8, which is displaceable along its axis at the level of the cylinder cores 5, 6.
  • the coupling element is made up of two coupling bodies 25 and 25 of similar shape, which are mounted on a central pin 26.
  • the latter is designed in form of a steel needle, the diameter of which is smaller than half of the length of the bores 27, 28 of the coupling bodies 24, 25 departing from the end faces facing each other. According to standard manufacturing tolerances, the coupling bodies 24, 25 thus rest on the pin 26 substantially free from any play.
  • the length of the bores 27, 28 is determined by the fact that the end section facing the cylinder core is designed to be cup-shaped.
  • the well length t amounts to approximately half of the axial length of the coupling body 24, 25.
  • the coupling bodies 24, 25 are urged to deflect by a spring 29 designed as a compression spring lying concentric with the pin 26.
  • the concentric location of the compression spring 29 relative to the pin 26 is assured by its end coils entering into annular grooves 30, 31 of the coupling bodies end faces, facing each other.
  • the length of the compression spring 29 is approximately equal to the total of the depth of the two annular grooves 30, 31 when the spring coils are completely compressed.
  • the pin 26 in the form of a steel needle has enlargements 32, 33 at its ends, which locate against the inside of the cup-shaped recesses 34, 35.
  • the deflected coupling bodies abut against these enlargements by their cup-shaped bottoms 24 ⁇ , 25 ⁇ .
  • the enlargement 32 here represents a collar of identical material to the steel needle 26, whilst the other enlargement 33 is formed by an inserted circlip 33. It is, however, also possible to produce the englarements 32, 33 by a severing tool, whereby the respective ends may be shaped like a screwdriver blade. The largest size of such an enlargement is thereby greater than the diameter of the bore 27, 28 so that the coupling bodies are fixed in their outer position.
  • the length of the steel needle or pin 26 is such that it is shorter than the combined length of the coupling bodies 24, 25. When the end faces of the coupling bodies 24, 25 abut, the pin 26 thus does not project beyond the outer end faces of the coupling bodies.
  • flanks 36, 37 project from the circumference of each coupling body 24, 25, designed such that the flank 36 is of smaller width than the flank 37.
  • These flanks 36, 37 are movable into shape-conformed slots 38, 39 of the discs 17, 18, which slots 38, 39 depart from a central opening 40, to allow the cylindrical portion of the coupling bodies 24, 25 to be entered.
  • the daylight gap between two opposite flanks of the coupling bodies 24, 25 is smaller than the thickness of the centre wall of the boss.
  • the ends of the cylinder cores 5, 6 facing each other are provided with location bores 41, 42, into which the corresponding end sections 24′, 25′ of the coupling bodies can enter.
  • location bores 41, 42 into which the corresponding end sections 24′, 25′ of the coupling bodies can enter.
  • width-confirming slots 43, 44 are milled into the location bores 41, 42 as shown in particular in Figure 6.
  • the coupling bodies are coupled in this way with the ends of the cylinder core facing them.
  • flanks 36, 37 project from the inner end faces of the coupling bodies 24, 25 facing each other spaced therefrom by a certain distance, so that a centering collar 45, 46 on the inside is left there for the engagement of the disc.
  • flanks 36, 37 are provided with detent shoulders A.
  • the shoulders A are disposed so that the flanks 36, 37 can engage into the discs 17, 18 to thickness of the discs.
  • the flanks 36, 37 moreover, extend in the plane of the keyway 15.
  • the flanks 36 are provided with a bevel 36′.
  • the coupling mechanism 9 is designed so that it allows locking from both sides, even if there is a key in the lock on the one side of the cylinder lock which has already been turned.
  • the cylinder lock is operated in the following way:
  • the coupling mechanism 9 takes up such a position, that the coupling body 24 on the LH side is coupled in positive engagement with the disc 17. It could however also be that the other coupling body 25 is in engagement with the other disc 18. If, in this position, the key 14 is inserted into the lock, then the pin tumblers are arranged by the indentations 14′ of the key such that their separating line T lies on the sliding joint of the cylinder core. It can now arise that the corresponding cylinder core 5 is turned by the key 14 through about 90 degrees. As a result of this, the corresponding coupling body 24 is taken along, which owing to the positive locking with the disc 17 also takes along the locking member boss 8.
  • the cylinder core 6 can now be turned by means of the key 47 while taking along the coupling body 25. As soon as the flanks 36, 37 of this coupling body 25 align with the appropriate slots 38, 39 of the disc 18, the compression springs 19 enter into action and displace the disc 18 into the postion taken up in Figure 8 while establishing the coupling connection between cylinder core 6 and the locking member boss 8. Upon further turning of the key 47 the opposite cylinder core is turned via the coupling mechanism 9.
  • a flat spring 48 which is formed by a twisted flat spring strip extends between the discs 17, 18.
  • the plan form of this flat spring 48 is approximately equal to that of the discs 17, 18.
  • the flat spring 48 has a central cut-out 49 to allow the coupling bodies to pass through.
  • a further alternatively-designed flat spring 50 is illustrated in Figure 10. Its plan form is also approximately equal to that of the discs.
  • This flat spring 50 is provided at its edge with deflected tongues 51, 51′ for abutting the discs 17, 18 and is provided at a central position with deflected flaps 52, 52′ for resting against the coupling bodies.
  • the tongues and flaps point towards each other in opposite directions.
  • Diagonally-extending supporting means are formed by the tongues 51, 51′, which substantially inhibit tilting of the discs. Since diagonal support is sufficient, it is also feasible to use only two compression springs in diagonal disposition in place of four single compression springs 19 in the first specific embodiment.
  • the locking member boss 8 is equipped with discs 53, 54, which are of greater thickness than the discs 17, 18.
  • the thickness of the centre wall of the boss has however remained the same. The extent of the axial displacement of the discs is reduced by this. This is done if an emergency coupling 9′ in accordance with Figures 13 and 14 is to be produced.
  • Axial displacement of the discs 17, 18 can also be restricted by arranging a centre disc 56 between them in accordance with Figure 12.
  • the centre disc is of approximately equal thickness to the two outer discs 17, 18 and is penetrated by the appropriate compression springs 19 acting on the discs 17, 18.
  • the construction of the cylinder lock illustrated in Figures 13 and 14 is similar to that of the first exemplary embodiment.
  • the mode of operation of the appropriate emergency coupling is as follows:
  • the cylinder lock cannot be locked from the opposite side by a normally-designed key, which is the same as the key 14. Locking from the opposite side is only possible by using a specially designed emergency key 55, which comprises longitudinal indentations 55′. If the emergency key 55 is inserted in accordance with Figure 13, then its key tip displaces the facing coupling body 25, which in turn displaces the disc 54 up to the stop position on he other disc 53. Because of the longitudinal indentations 55′, the pin tumblers impinged by the emergency key 55 are duly aligned in this position. The cylinder core 6 can now be turned by the emergency key, so that the flanks 36, 37 are moved into alignment with the flanks of the other coupling body.
  • Normal coupling could be produced by forming the discs of such a thickness, that their total thickness equals the thickness of the centre wall 10 of the boss. If this is the case, the corresponding single compression springs 19 can then be dispensed with.
