Definitions

  • the present invention relates to a security device and more specifically to a latching device for coin locks of the kind defined in the preamble of Claim 1.
  • the invention relates to a method of activating and releasing a latching device used in such coin locks.
  • locks of this kind are delivered from the factory with the key fitted in the lock, there bulk presents a delivery packaging problem.
  • the keys can only be removed from these locks when the correct coin is inserted into the coin slot. This enables a hooked arm to be swung out to a latching position.
  • the lock mechanism is adapted to the size of the coin for which the lock is intended, whereafter the lock is tested to ensure that it operates in the correct. This test is carried out either with the aid of a correct coin or with the aid of a dummy coin.
  • the manufacturer of cabinets, lockers, etc., fitted with coin locks also experiences problems in delivering the cabinets. If the cabinets are transported with the keys fitted in the locks, the cabinet doors will be unlocked and the keys will project out, and therewith take up space, and are at risk of being bent or broken. The keys are also liable to damage adjacent cabinets. The doors must be kept closed, for instance with the aid of adhesive tape. If the doors are locked with the use of an appropriate coin, the coin must accompany the cabinets during their transportation.
  • One object of the invention is to eliminate these drawbacks, so that after being finally tested in the factory, the coin lock can be delivered in a thinner and more convenient package without the key of the lock cylinder being held in the key slot and projecting therefrom.
  • Another object is to enable the manufacturers of cabinets, or lockers, fitted with a coin lock to be delivered in a simpler and less expensive manner. It shall be possible to lock the doors without the aid of a coin, i.e. the coin shall no longer accompany the cabinet during its transportation.
  • Another object is to ensure that the coin locks of cabinets installed in a user location will function reliably when using a prescribed coin.
  • an object of the invention is to provide a method of activating a coin lock latching device which enables the lock latching device to be fitted in the factory in conjunction with the manufacture of the lock, and which enables the coin lock to be finally tested prior to delivery with the latching device in a resting mode, and to activate the latching device such as to enable the lock to be packaged and delivered without its key projecting out from the lock cylinder.
  • the inventive latching device may have a very simple construction and, in practice, will conveniently comprise a hooked rod, preferably a plastic rod.
  • the cost of the latching device is very small, and in fact the cost of the latching device is far less than the cost entailed by the additional coin-lock packaging material that is required when the key is fitted in the lock upon delivery and projects out from the cylinder lock. Added to this latter cost is the cost entailed by transporting cabinets fitted with such locks.
  • the latching device will, in practice, preferably include a fracture weakening or like means at which said device will break as a result of the application of force when the lock is prepared for use in the location in which the cabinet shall be used.
  • the rod or wire includes a preferably hook-like protrusion for coaction with the lock housing in the region of the rod accommodating hole, so as to determine the position of the lock-mechanism hook in which the hooked catch member can be swung, i.e. when the latching device is activated.
  • the latching device protrudes from the lock housing through two or more labyrinth-forming holes or openings. This makes it much more difficult for unauthorized persons to manipulate the lock mechanism when the coin lock is unlocked with the key in the lock.
  • the invention relates to a method of activating a latching device of the aforesaid kind that has the characteristic features set forth in the characterizing clause of Claim 6.
  • Locking device at rest means that the latching device is fitted to the lock housing.
  • the lock functions with the appropriate coin.
  • Locking device activated means that the latching device is extended to a latching position.
  • the lock functions without a coin.
  • Locking device released means that the latching device is withdrawn from the lock housing, wherewith the device has fractured at its fracture weakening or, alternatively, has overcome the requisite frictional force.
  • the lock functions with the appropriate coin.
  • Fig. 1 is a side view of a conventional coin lock which an is to be fitted with an inventive latching device.
  • the side of the lock shown in the Figure is pressed against the object to be secured, e.g. the door of a cabinet or locker.
  • Fig. 2 is an end view of the coin lock shown in Fig. 1.
  • Fig. 3 is a side view of the exterior side of the coin lock.
  • Fig. 4 shows the coin lock of Figs. 1-3 from above.
  • Fig. 5 is a side view of a coin lock according to Figs. 1-4 with the outer side wall removed so as to show an inventive latching device fitted to the lock mechanism.
  • the latching device is therewith mounted at rest so as to enable the lock to be finally tested prior to delivery.
  • Fig. 6 is a view corresponding to Fig. 5 and shows the latching device in an active position and the hook of the lock mechanism in a free position, with the hooked catch member swung outwardly so as to enable the key to be removed from the lock.
  • Fig. 7 is a view corresponding to Figs. 5 and 6 and shows the latching device extended and the hooked catch member swung inwardly to a free position so as to release the latching device.
  • Fig. 8 is a view corresponding to Fig. 7 and shows the lock subsequent to the insertion of a coin, wherein the hook has been omitted for the sake of clarity.
  • Fig. 9 is a side view of a preferred embodiment of an inventive latching device.
  • Fig. 10 is a modified version of the latching device shown in Fig. 9.
  • Figs. 1-4 illustrate a coin lock 1 of conventional design from different aspects.
  • the coin lock comprises a housing or casing 2 that includes an upper coin slot 3, a coin collection cup 4, a pivotal hooked catch member 5, and a cylinder lock 6 whose key (not shown) can be removed by inserting the correct coin (not shown in Figs. 1-4) into the coin slot and turning the key so as to bring the hooked catch member to its illustrated locking position.
  • the hooked catch member cannot be held in an inwardly swung position when the coin lock is delivered from the factory without including an appropriate coin. It is therefore not possible to remove the key from the cylinder lock.
  • the lock package is therefore unnecessarily bulky and awkward.
  • Fig. 5-8 show the interior of the lock housing 2 with the lock mechanism in different operational states, with the outer side of the lock housing having been omitted for the sake of illustration.
  • Fig. 5 and 6 show the lock with an inventive latching device fitted, wherein Fig. 5 shows the latching device in its rest state in which the lock mechanism can be finally tested prior to delivery from the factory.
  • Fig. 6 shows the inventive latching device in an activated position in which the coin lock can be packaged and delivered with the key removed without requiring a coin to be inserted through the coin slot.
  • Fig. 5-8 illustrate further components of the lock mechanism, among other things.
  • An intermediate member 10 includes a pin 9 by means of which the member 10 is coupled to a hooked catch member 5. Pivotal movement of the hooked catch member in different directions effected through the medium of dogs (not shown) on the lock cylinder 6 is converted to generally rectilinear movement so as to move the intermediate member 10 forwards and backwards between a rear end position (shown in Fig. 7) and a forward end position (shown in Fig. 6).
  • the mechanism also includes a hook 11 which coacts with the intermediate member 10, the hooked catch member 5 and a coin 7 shown in Fig. 8.
  • the hook 11 functions to limit movement of the intermediate member, and therewith also movement of the hooked catch member 5, until a coin 7 is inserted (Fig. 8), whereupon the latching effect of the hook 11 ceases and the hooked catch member 5 can be swung by the dogging member.
  • the intermediate member 10 is herewith moved to its forward position.
  • a latching device in the form of a wire or a plastic rod 13 of comparatively small diameter whose one end is provided with a hook 11 and whose other end projects out through a hole provided in the lock housing 2, as explained in more detail herebelow and as shown in Fig. 5.
  • the latching device 13 is at rest in the Fig. 5 illustration.
  • the final manufacturing stage includes adapting the lock mechanism to the required coin size, and testing the function of the latching device.
  • Adaptation of the lock mechanism to the required coin size includes, among other things, determining the relative position of the illustrated pin 17 in relation to the pin 18 and mounting the pin 17 in said position, i.e. a position in which an inserted coin 7 will rest against the pins 17 and 18 in the manner desired and carry out the intended function (c.f. Fig. 8).
  • the coin lock is subjected to a final test prior to delivery, with the latching device 13 in its rest state (Fig. 5).
  • the latching device is activated before packaging and delivering the coin lock.
  • the latching device is activated by applying tension to the rod 13, such that a hook-like protuberance 13b located a short distance from the end of the rod 13 can be inserted in the hole provided in the lock housing 2 herefor, i.e. the latching device is pulled-out to a device latching point.
  • the protuberance prevents the latching device 13 from moving back into the lock housing.
  • the hook 11 is therewith swung up from the position shown in Fig. 5, therewith enabling the hooked catch member 5 to be swung outwards and the lock key to be removed from its slot.
  • the coin lock can now be packaged for delivery.
  • Fig. 7 illustrates the process of releasing the latching device at the place of use.
  • the latching device 13 is again pulled-out with the aid of a suitable tool (not shown), the force applied being sufficiently great to cause the latching device to break at a fracture weakening 13a provided on its other end carrying the hook 11.
  • the coin lock is then ready for use.
  • the latching device 13 extends from the housing 2 through two openings 15 and 16 which are out of alignment with one another. These two openings can be said to form a labyrinth passageway which makes it more difficult for an unauthorized person to manipulate the lock mechanism from outside the lock, with regard to conventional use of the coin lock.
  • Fig. 9 illustrates in side view an inventive latching device in the form of a plastic rod 13 that includes a fracture weakening 13a and hook-like protuberances 13b.
  • the latching device also includes on one end an anchor 13c for coaction with the hook 11. The anchor thus remains on the hook 11 subsequent to breaking the device at the fracture weakening 13a.
  • Fig. 10 illustrates a modified version of the latching device 13 which lacks the provision of a fracture weakening.
  • the latching device is subjected to a sufficiently high pulling force, the part 13c will be pulled loose through attachment holes intended to this end.
