Definitions

  • the invention relates to a convertible lock for room doors and valuables with two locking mechanisms assigned to the management and the customer, which independently operate a common bolt.
  • the invention relates to the use of conversion locks in the hotel sector, in office facilities or in valuables in general.
  • Electronic locks have recently been used which are actuated with electrically coded keys or magnetic cards. Electronic locks can be easily reprogrammed every time you change guests. However, these locks require extensive wiring for power supply. On this occasion you also have to lay signal lines in order to display the closed status of all doors centrally. Retrofitting hotel facilities is very expensive due to the required wall openings. Another disadvantage is that electronic systems are more susceptible to faults than purely mechanical solutions, so they require increased maintenance.
  • the invention has for its object to provide a lock system that can be easily changed with high copy security and is particularly suitable for retrofitting hotel systems.
  • the basic idea here is that the manager can change the customer lock to a key of a different coding each time a guest or customer changes or even when a key is lost, so that misuse is virtually impossible.
  • the lock is placed on the existing room door lock as a box lock with minor conversion measures after the latches, lock shields and lock cylinders have been removed.
  • the attachment takes place with With the help of screws that are inserted from the inside.
  • the same lock system can also be used as a mortise lock for new buildings.
  • Fig. 1 denotes the door leaf, in which a standard lock 2 is inserted.
  • the latch carries the number 3, the bolt no longer required the number 4.
  • the novel lock with the protective housing 5 is attached. You can see the elongated keyholes 6 and 7 for double-bit keys.
  • the housing 5 is fastened with hidden screws from the inside of the door.
  • FIG. 2 shows above the lock plate 8 a handle 9 which actuates the latch 3 via the usual lock nut.
  • Another handle 10 serves to block the trap movement. This is to prevent room service from unlocking from the outside if the guest does not want to be disturbed.
  • a marking arrow 10a indicates whether the lock is locked or not.
  • the revealing view of the actual lock according to FIG. 3 reveals the U-shape of the housing 11.
  • a flat cover 12 shows different elongated holes and the key holes 6a, 7a. It is fastened by means of the screws 25, 26.
  • Fig. 4 shows the details of the U-shaped lock housing 11. It can either consist of folded sheet metal or be made as a die-cast part. Elongated side walls 11b, 11c adjoin the base plate 11a. Two guide columns 11d, 11e with threaded holes are arranged in the axis of symmetry. A larger circular opening 11f serves to support a lock nut shown in FIG. 5. A smaller opening 11g leads to a locking disk which can be seen in FIG. 5. Four threaded holes 11h, 11i, 11j, 11k are used to fasten an intermediate cover according to FIG. 6. Recesses 111, 11m, 11n, 11o are provided on the side walls 11b, 11c for guiding the cover according to FIG. 11.
  • a recess 13a includes the nose 14a of the lock nut provided with a square hole.
  • the locking disc 15 assumes a position in which its corner 15a blocks the slide 13 via a locking lug 13d. A left turn of about 30 ° releases the lock.
  • a guide pin 15b slides in a slot 16a of an intermediate cover 16, so that the rotational movement of the locking disk is limited.
  • the slide 13 carries two drive pins 13b, 13c which engage in the tour pin slide according to FIG. 9.
  • FIG. 6 has two key pins 16b and 16c in addition to different openings.
  • Another mandrel 16d serves as a journal for a control lever (Fig. 7).
  • a mandrel 16e engages in the change-over slide (FIG. 8) and a tour pin slide (Fig. 9).
  • FIG. 7 shows an intermediate slide 17 which has a control curve 17a for the management key. It is also important to have a recess 17b which, when the slide is adjusted, takes the pin 15b with it and releases the main slide 13. In emergencies, the manager can open the door even if it is locked from the inside. Furthermore, a pin 17c is provided, the meaning of which will be explained later.
  • the intermediate slide 17 also actuates a control lever 18, the control pin 18a of which locks the lower tour pin slide (FIG. 9) when the management key is turned through 180 °.
  • the tour pin slide 21 for the management lock is arranged above the tour pin slide 22 of the customer lock.
  • the control cams are designated 21a, 22a, the tour pins 21b, 22b.
  • tumblers 23, 24 are shown, which lie as packets on the slides 21, 22.
  • the slots 23a, 24a encompass the columns 11d, 11g in FIG. 4.
  • the tooth regions 23b, 24b are retained by the pins 19b and 19c after recoding.
  • the tumblers 24 have a very special shape: they show a widening at the bottom right with an inlet funnel 24c. When the management key is turned, the slide 17 goes up and the pin 17c aligns the tumblers 24 uniformly. When changing the lock to a new customer key, it is therefore not necessary that the previous customer key is inserted and operated.
  • the handling of the new lock is as follows: The customer or guest puts his key in the lower keyhole, turns the key until the door is released, turns the key back and removes it.
  • the upper handle is used for opening from the inside.
  • the guest receives any new key that the manager uses to switch the lock to this selected key. To do this, he inserts the management key into the associated locking mechanism, turns it 180 ° to adjust the change-over slide 19, inserts the customer key, and turns it 90 °. If the management key is now turned back and removed, all the tumblers of the customer's locking system are changed over to the key introduced.
  • the locks can also be changed when changing guests on each floor by changing the locks from door to door and immediately attaching the key fobs with the room numbers to the selected keys.
  • the conversion lock described so far is very well suited for retrofitting because you only have to remove the door handles, lock plates and the lock cylinder without having to remove the standard mortise lock. Then you drill two or four new fastening holes with a drilling jig, put the lock on with the square pin, screw it to the inner lock plate and fasten the handles. Since the protective housing and the new lock plate can be chosen larger than the old fittings, it is not even necessary to touch up the paint on the door leaf.
  • the longitudinal axis of the lock housing is vertical.
  • the main slide 13 is extended by a bolt or a latch mounted on the slide.
  • the box lock can also be attached to the back of security doors, especially room safes. It is preferable to use the same key for the room door and the safe. This has the advantage for the guest that he only has to carry one key and that he does not constantly confuse two similar keys. For security reasons, however, a special management key is used for the room safe so that the floor staff have no access to the room safes.
  • the mandrel 16b can have a larger opening have knives than the mandrel 16c.
