Definitions

  • the present invention relates to a locking device comprising a lock cylinder and a flat key, which key has locking indentations along the surface of its broad side and, in the area of the front of the key, is provided with at least one entry slot located in alignment with the locking indentations to receive the pointed heads of the non-pivotally mounted plug pins, so that the bottom of the entry slot forms a control face for plug pin displacement.
  • the present invention further relates to a flat key of the type detailed in the preamble of claim 23 and to a blank for a key of the type detailed in the preamble of claim 25.
  • German Patent Specification No. 26 60 959 C2 It is known from German Patent Specification No. 26 60 959 C2 to provide a lock in which, when the key is inserted in the keyway the bottom of the entry slot engages the pointed head of the plug pin at the point which is furthest away from the bore of the pin. This will inevitably result in the formation of tilting forces, which provide additional resistance to the insertion of the flat key, which is also found with the arrangement of the plug pins of known lock cylinders.
  • the present invention provides a locking device which comprises a lock cylinder and a flat key, which has locking indentations along its broad-sided surface and, in the area of the front of the key, is provided with at least one entry slot lying in alignment with the locking indentations for receiving the pointed heads of the non-pivotally mounted plug pins in which the bottom of the entry slot forms a control face for plug pin displacement, characterised in that each plug pin has, at a distance from its pointed head, at least one drive bevel impingable by the key which, viewed in the insertion direction of the key, lies at the side close to the corresponding pointed head.
  • the invention further provides a flat key according to claim 23.
  • Said key has locking indentations along its broad-sided surface and, in the area of the front of the key, is provided with at least one entry slot lying in alignment with the locking indentations for receiving the pointed heads on the non-pivotally mounted plug pins in which the bottom of the entry slot forms a control face for plug pin displacement.
  • the invention further provides a blank for this flat key according to claim 25.
  • a further advantageous feature in accordance with the invention is that the flat key adjacent to the entry slot comprises a control zone cooperating with the drive bevels of the plug pins.
  • the area remaining at the side of the entry slot thus represents a control zone, which acts upon the drive bevel when the key is inserted.
  • the pointed head is formed onto a flat rib extending in the longitudinal direction of the keyway. This is the design if each plug pin is provided with two drive bevels. The thickness of the flat rib must always be matched to the width of the entry slot. It is therefore advantageous for the flat rib to lie concentric with the centre of the plug pins, so that each run-up bevel is sufficiently utilised.
  • the drive bevels are simple to manufacture since the step-like transition region between the flat rib and the adjacent plug pin circumference forms the drive bevel.
  • control zone In order to allow the drive to advance with very little effort, the control zone is designed as control face running inclined to the longitudinal direction of the key shank. In this way the tractive stress between drive face of the plug pin and control zone of the key is reduced.
  • the control zone or control face is formed as a chamfer onto the side of the entry slot.
  • the drive bevel starts at the entry end by maintaining a distance to the adjacent keyway wall. Then when the key is inserted the control zone close to the adjacent keyway wall becomes effective, in the near vicinity of the bore of the pin, while minimising any tilting forces acting on the plug pin. That means that even if the inclined face were to start in the bore of the pin, a simple bifurcation would suffice to produce the entry slot.
  • the bottom of the entry slot extends from the one broad side of the key up to the other.
  • the arrangement of the plug pins is also assisted by the fact that the angle of inclination of the bottom of the entry slot corresponds to the angle of inclination of the run-up ramp.
  • a further advantageous feature of the present invention is that the angle of inclination of the drive bevel relative to the insertion direction of the key is smaller than the correspondingly related angle of inclination of the control face. In this case, edge-like contact between the drive bevel and the control zone results.
  • the recesses are formed by a continuous slot.
  • the recesses are formed by indentations spaced at intervals from each other matching the shape of the pointed heads. Only the smooth shank of the plug pin is then available to a picking instrument as an engagment surface, so that its displacement is effectively impossible unless a proper flat key is used. A key which has the correct recesses, but is not appropriately designed in the region of the entry slot, would also not be able to displace the plug pins.
  • the end of the entry slot bottom lying at the insertion end is set back relative to the front of the key, in the direction of the lengthwise extension of the key.
  • the broad side of the key comprises a projecting longitudinal rib, into which at least one locking indentation formed on the opposite broad side of the key extends.
  • the flat key is therefore made thicker which allows the number of step drops to be increased without having to reduce the dimensions of the step drop.
  • the design can preferably be arranged so that the end of the bottom of the entry slot lying at the insertion end departs from the crest of the longitudinal rib.
  • the end of the longitudinal rib lying at the insertion end is set back relative to the front of the key in the direction of the lengthwise extension of the key. In this way a centering end is provided, which assists in the insertion of the key into the keyway.
  • the flat key according to the invention can be designed as a reversible flat key. If the associated lock cylinder comprises a single row of pin tumblers, then the reversible flat key on each broad side is to be provided with one row of recesses, which are positioned staggered relative to each other.
  • a locking device comprises a lock cylinder 1 and a reversible flat key 2.
  • the lock cylinder 1 comprises a cylinder housing 3, which is provided at its front end with a flange 4.
  • the stepped-down section adjoining the flange is threaded along its circumference.
  • the latter is locked in position in the axial direction.
  • the cylinder plug 6 is penetrated by a keyway 7 extending along the longitudinal direction, the one narrow side of which extends up to the cylinder plug bore 5.
  • Continuous slots 10, 11 depart from the keyway walls 8, 9 staggered relative to each other, and having a trapezoidal cross-section.
  • the cylinder plug 6 Running perpendicular to the keyway 7 the cylinder plug 6 is provided with consecutive drop shaped plug pin bores 12 for housing cross-sectionally matched plug pins 13, the pointed heads 14 of which project into the keyway 7 and engage the slot 10 or rest against its bottom.
  • the non-pivotally mounted plug pins 13 are pushed into this position by housing pins 15, which on their part are displaceably mounted in housing bores 16. The latter align with the corresponding plug pin bores 12 and house pin-springs (not shown herein), which transmit their force through the housing pins 15 to the plug pins 13.
  • Each plug pin 13 is provided, spaced by a short distance from its front, with two drive bevels 17 impingable by the reversible flat key 2.
  • the bevels 17 - viewed in the insertion direction of the key - lie at the side close to the pointed head 14, which is formed on a flat rib 18 extending in the longitudinal direction of the keyway so that it lies concentric with the centre of the plug pins.
  • the drive bevels 17 are formed by the step-like transition region between the flat rib 18 and the adjacent plug pin circumference M.
  • the appropriate reversible flat key 2 comprises a key handle 19, (see Figure 4) and a partially illustrated key shank 20. Its cross-sectional profile resembles that of the keyway 7.
  • each broad side of the key B departs one longitudinal rib 21.
  • the longitudinal ribs are staggered relative to the longitudinal centre axis of the key.
  • the cross-sectional shape of the longitudinal rib 21 resembles that of the slots 10, 11 in the keyway walls 8, 9.
  • indentations 22 are provided to arrange the tumbler pins. According to the dash-dotted representation in Figure 5 it is possible, that the indentation 22 extends as far as into the longitudinal rib 21.
  • the locking indentations 22 of each row of recesses are integrated to a continuous slot of different slot bottom level such that the slot bottom levels of adjacent indentations 22 are connected to each other by slot bottom faces running rectilinearly.
  • a boring cutter can therefore be used, the diameter of which corresponds to that of the plug pins 13.
  • each entry slot 26 is arranged at the front of each web 25. Its width corresponds to that of the web 25. Additionally, each entry slot 26 is matched to the width of the flat rib 18 of the plug pins 13.
  • the reversible flat key 2 further comprises, adjacent to each entry slot 26, control zones 27 which cooperate with the drive bevels 17 of the plug pins 13, the control zones 27 of which are designed as control faces extending at an inclined angle to the longitudinal direction of the key shank.
  • the control zones 27 are thereby at the level of the shank slots 23, 24 and are arranged in front of the bottom 28 of the entry slot 26. The latter extends from the one up to the other broad side of the key.
  • the flank 29 of the pointed head 14 at the insertion end together with the inclined-extending bottom 28 of the entry slot 26 forms a run-up ramp.
  • the angle of inclination, alpha, of the bottom 28, relative to the key insertion direction corresponds to the angle of inclination of the run-up ramp or flank 29 of the pointed head of the plug pins 13.
  • the angle alpha is approximately 45°.
  • the angle of inclination alpha′ relative to the key insertion direction of the control zone 27 designed as control face corresponds to the angle of inclination alpha.
  • the angle of inclination beta relative to the key insertion direction of the drive bevel 17 is however smaller than the corresponding relative angle of inclination alpha′ of the control face or control zone 27. That means that the imaginary extensions of drive bevel 17 and run-up ramp 29 intersect at a point P.
  • the end 28′ of the entry slot bottom 28 lying at the insertion end is set back relative to the front of the key in the direction of the lengthwise extension of the key.
  • the edge-shaped end 28′ occupies a protected position.
  • the end 21′ of the longitudinal rib 21 lying at the insertion end is set back relative to the front of the key in the direction of the lengthwise extension of the key.
  • This end 21′ extends sloping upwardly in direction of the key handle 19 and lies a distance away from the end 28′ of the bottom 28.
  • an approach end is established in the area of the front of the key which, assists the insertion of the reversible flat key 2.
  • the plug pin 13 has then already been displaced to a great extent into its bore 12, so that any tilting forces are minimised. With the abutment of the bottom 28 against the run-up ramp or flank 29 an accelerated displacement of the plug pin 13 now follows on account of the greater angle of inclination alpha of the bottom with regard to the angle of inclination beta of the drive bevel 17, so that the drive bevel 17 is moved away from the control zone 27.
  • the plug pin 13 is thus pushed back during key insertion, firstly by impingement of the drive bevel 17 and afterwards by impingement of the run-up ramp or flank 29.
  • the transfer point thereby depends on the position of the bottom 28, the control zone 27 and the drive bevel 17. It is possible that the angle of inclination of the control zone matches that of the drive bevel.
  • the lock cylinder is a sectional semi-cylinder 30. It supports a cylinder plug 31 and is provided with two rows of tumbler pins such that the pins of the one row are staggered relative to the pins of the other row. The two rows of tumbler pins are thereby arranged equidistantly from the centre of the cylinder plug.
  • Each pin tumbler comprises a plug pin 32 and a housing pin 33.
  • the plug and housing pins 32, 33 are also of a drop-shaped contour in cross-section so that they do not rotate.
  • the plug pin bores 34 and housing bores are designed appropriately.
  • the plug pins 32 are of similar design. Corresponding portions of the pins are identified by the same reference numbers.
  • the keyway 35 is offset by a small degree relative to the centre of the plug. This offset is necessary, so that on the corresponding reversible flat key 36 entry slots 37 can be arranged for each row of recesses, the bottom 38 of which slot extends from one, up to the other, broad side of the key. In extension of the bottom 38 on each broad side two rows of locking indentations 39 are provided so that the rows of recesses on the one broad side of the key are offset relative to those of the other broad side of the key. In each case two adjacent entry slots 37 and their bottom 38 intercross into each other. Adjacent to the entry slots 37 are control zones 40, 41, which are also designed as slanting control faces.
  • each entry slot has only a single control zone 40 or 41. That means that when the key is inserted only one control zone comes into contact with the drive bevel 17 of the plug pins 32 at one time. As shown in Figure 14, this means that the control zone 40 of the operative entry slot 37 lying at the outer right hand side comes into contact with the right hand drive bevel 17 of the plug pin lying at the right hand side.
  • the bottom 38 of the entry slot lying at the inner end of the left hand half of the key then impinges the plug pins 13 lying in the left hand row, so that the associated control zone 41 displaces the right hand drive bevels 17 of the plug pins lying at the left hand side.
  • the end 38′ of the bottom 38 of the entry slots 37 at the end of the front of key is also set back to a certain extent relative to the front of the key.
  • the entry slot bottom 38 and the control zones 40, 41 share the same angle of inclination. With the insertion of the reversible flat key 36 the same stages occur as in first embodiment ( Figures 1 to 10).
  • the control zone 40 or 41 first impinges the drive bevel 17. Only after partial displacement of the plug pin the bottom 38 further displaces the plug pin by impinging its flank or run-up ramp 29. The drive is possible even if the pointed head 14 of the plug pins are located completely in recesses 42 of the keyway wall 43.
  • the recesses 42 are formed by indentations spaced at intervals from each other matching the shape of the pointed heads 14.
