Definitions

  • This invention relates to a locking arrangement for dead bolt latch locks, especially for hotel guest room doors, provided with a tumbler cylinder plug operated from outside by a key, with a turn knob coaxially arranged relatively to said tumbler cylinder plug on the inside as well as with two bolt actuating cam hubs rotatable in position between the knob and plug for latch and dead bolt operation.
  • Such a lock intended to be used for guest room doors in hotels is supposed to meet the following requirements: It must be capable of being operated to release position from outside by the hotel guest by means of the corresponding guests key and capable of being bolted from inside by means .of the turn knob. Moreover, it must also be possible that the lock can be released from outside bythe room maid by means of the key,.unles's it is bolted from inside by means of the turn knob.
  • the hotel manager or administrator must-also be able to release the lock from outside by means of the corresponding key, even if it is bolted frominside and, in addition to that, it must also be possible to be locked from outside in case of special incidents so that it cannot be released by means of the guests key or the room-maids key.
  • a hotel room door lock of the above design meeting the aforesaid requirements is already known. It is provided with latch bolt and dead bolt and, additionally, with a night bolt that can be projected by means of the inside turn knob.
  • the tumbler cylinder is designed for master key operation, and permits the night bolt to be retracted-by means of the administrators key designed to be a master key.
  • the dead bolt can be projected in two turns by means of the master key, whereas the guests and the room-maids keys project the deadbolt in single turns only.
  • this lock cannot be released by means of the last-mentioned keys, if locked in two turns by means of the master key.
  • a disadvantage, however, of this known locking arrangement is that the lock requires an extra night bolt besides the normal dead bolt.
  • the turn knob for the night bolt is mounted on the exterior hardware, which makes it difficult in practice to mount it in the lock so as to be flush with the night bolt hub to permit the night bolt to be moved with sufficient ease by means of the corresponding key.
  • the present invention has for an object the provision of a locking arrangement for dead bolt latch locks to be installed mainly in hotel guest room doors not having the above-mentioned defectsbut rather being so constituted that the aforesaid requirements can also be realized with a normal latch bolt lock, i.e., not provided with an additional night bolt.
  • this object is attained according to the invention in that the latch retracting cam hub is in constant non-rotatable relation to the turn knob shaft and can be operated by the guests and administrators keys that may be inserted, and that there is an axially slidable coupling member that is coaxial with the turn knob shaft and nonrotatable relatively to said turn knob shaft, said coupling member connecting the turn knob shaft with the cam hub that actuates the dead boltwhen the administrator's key is inserted and also when no key is present.
  • the coupling member will, however, disconnect the turn knob shaft from thecam hub, if the guest's key is inserted.
  • This locking arrangement may be used with the lock construction that is shown by the United States patent to Perlick and Duerhagen, No. 3,63 1,695.
  • the latch retracting cam hub is advantageously arranged to face the tumbler cylinder plug and the deadbolt operating cam hub is arranged to face the turn knob shaft
  • the coupling member is mounted in the turn knob shaft designed to be hollow and is axially slidable against the action of a compression spring accommodated in said hollow turn knob shaft, a coupling rib laterally projecting from the coupling member and coacting with a coupling slot provided in the bolt operating cam hub and a thrust piece having a key-engaging slot arranged on the front end being incorporated and the guests key still featuring an elongated key tip in comparison with that of the administrators key.
  • FIG. 1 shows a longitudinal section through the locking arrangement with the guests key inserted
  • FIG. 2 shows a longitudinal section corresponding to FIG. 1, but with the administrators key inserted
  • FIG. 3 shows a cross-section along the lineA-B of FIG. 1 and FIG. 4 shows a cross-section along the line C-D of FIG. 2.
  • the tumbler cylinder plug 2 whose axial movement is prevented by snap ring 3 engaging with annular groove 2' is rotatably mounted invlock cylinder case 1.
  • pin tumblers 6, 7 acted upon by spring 5 secure plug 2 against turning.
  • the depth of bittings 8 provided on keys 4 and 24 is so proportioned to the length of pin tumblers 6, 7 that all of these pin tumblers are moved when the keys are inserted so that the common contact areas between pin tumblers 6, 7 are shifted to the circumference located between cylinder case 1 and cylinder plug 2, thus discontinuing the locking by pin tumblers 6, 7 so that cylinder plug Zcan be turned in case 1 as is conventional.
  • a turn knob shaft 10, designed as a single piece securely connected to turn knob 9, is mounted in case 1 coaxially with cylinder plug 2.
  • the turn knob shaft 10 is secured against axial movement in case 1 by snap ring 11 engaging with annular groove 10'.
  • a coupling member 13 is acted upon by compression spring 12 and is mounted in bore 10" of turn knob shaft 10 so as to be axially slidable. It has a coupling rib 14 arranged to project laterally so as to be guided in the axially extending guide slot 10" of turn knob shaft 10, making coupling member 13 nonrotatable relatively to turn knob shaft 10. In the coupling position of coupling member 13 illustrated in FIG. 2, coupling rib 14 engages with the correspondingly shaped coupling slot (FIG.
  • cam hub 15 for operating the deadbolt, not shown.
  • the cam hub 15 is provided with an annular collar 16 through which it is rotatably mounted in case 1.
  • IDAMO unintentional IDAMO
  • braking pin 25 is arranged in hotel of the case so as to be radially movable, said braking pin being pushed against annular collar 16 of locking cam hub 15 by compression spring 26.
  • a latch retractingcam hub 17 is rotatably arranged at the inner end of tumbler cylinder plug 2.
  • the coupling dogs 19 protruding from the front end of turn knob shaft 10 engage with the coupling slots 18 of locking cam hub 17 (cf. FIG. 4), so that hub 17 will rotate integrally with turn knob shaft 10 and turn knob Unlike the administrators key 24, the guests key 4 has a lug 20 at the key tip by which, according to FIG.
  • the administrators key 24 has, as already mentioned, no extension lug 20 at its key tip 24.
  • the administrators key 24 can therefore notpush back thrust piece 21 nor coupling member 13, so that deadbolt operating cam hub 15 remains coupled with turn knob shaft 10 via coupling rib 14. Consequently, the two cam hubs l5 and 17 can be turned by the administrators key 24, and that key can both retract the latch bolt and operate the dead bolt.
  • deadbolt operating cam hub 15 will remain in coupling engagement with coupling member 13 and turn knob shaft 10 via coupling rib 14, if no key is inserted in tumbler cylinder plug 2.
  • both cam hubs 15, 17 are connected to turn knob 9 so that both the latch bolt and the dead bolt of the lock can be actuated by it.
  • the room-maids key is as long as the guest's key 4, that what has been mentioned above with regard to the guests key 4 is also true of the former.
  • the room-maids key 4 is effective only to rotate the latchbolt retracting cam hub 17.
  • the maids key cannot effect release should its deadbolt have been placed in locking position, whether by turning of the turn knob from inside or by locking from outside by means of the administrators key 24.
  • thrust piece 21 and coupling member 13 which'are pressed springs 22 and 12 independently of each other. That enables thrust piece 21 and its engaging slot 21 to be reached and actuated by the shorter administrators key 24 at any time.
  • This will, in particular, be required in the ev t of co lin membe 13 b in in its u e back position and urn ed roun relative y to d ad 0% operating cam hub 15, as might have been brought about when a previous actuation by the guest room key 4 has left coupling member 13 in a position in which coupling rib 14 cannot pass into coupling slot 15 of hub 15.
  • the administrators, key 24. is insertedand turned in this situation, when thrust piece 21 has been partially moved forward out of couplingrnember 13, the coupling member 13 will co-rotate so that itsrib 14 can enter coupling slot 15.
  • Locking mechanism characterized in that the latch retracting cam hub (17) is mounted in position intermediate the pin tumbler cylinder plug (2) and the deadbolt operating cam hub (15), and that the coupling member (13) is supported in a boring (10") in the turn knob (10) and movable in that boring against the action of a compression spring (12), said coupling member (13) being provided with a laterally projecting coupling rib (14) coacting with a coupling slot (15 in the deadbolt operating cam hub (15), as well as with a contact piece (21) having a key engaging slot (21') at its front end, and that the guest key (4) has an extended tip (20) for engaging said key engaging slot.
  • Locking mechanism characterized in that the contact piece (21) is connected to the coupling member (13) ina manner not allowing rotary motion, and is provided with a guide pin (23) which is axially movable against the action of a spring (22) in a reduced portion of the longitudinal boring in the turn knob, and that the coupling rib (14) formed on the coupling member (13) is guided in an axially extending guide slot (l0"') in the turn knob.
  • Locking mechanism characterized in that the deadbolt operating cam hub (15) is provided with a ring-shaped collar (16) against which a spring (26) presses a brake pin (25) that is radially movable in the shell of the pin tumbler cylinder.
