Definitions

  • This invention deals with a lock of the type that uses a perforated card as a key or opening element; this lock is, therefore, specially apt for hotels and, generally speaking, for any situation which makes it necessary or practical to modify the opening code with a certain periodicity.
  • Unlocking takes place when a key is inserted in the lock, forcing the pin-­counterpin assembly to move axially in different magnitudes for each one of the pairs and, more specifically, in concrete magnitudes that cause the union plane between each pin and its counterpin to coincide with the union plane between the fixed and movable elements, enabling the latter to rotate or move longitudinally with respect to the former.
  • this unlocking is only achieved when a key with the suitable code is inserted into the lock, one which is designed to cause the exact axial movement of each pin-counterpin.
  • the lock proposed in this invention constitutes a major step in this environment, that is, in the field of card-actuated, variable-code locks, since, as will be shortly shown, this lock does not require the classic matrix to complement each of the cards or keys to be used by it; this lock has its own means for adjusting to each and every one of the key codes to be used with it.
  • the invention concentrates in the installation of an auxiliary part in each hole or joint housing where the fixed and movable elements in the lock, inside which the respective pin-counterpin sets are housed.
  • This auxiliary part which is a washer or similar item, may be radially removed from the relevant housing, causing the pins that were actuated upon by these auxiliary parts to present a set effective length, different from that of the pins lacking these parts. Therefore, in order to do the opening operation, a key must be inserted which has holes or perforations to correspond with all those pins which have an auxiliary part added.
  • To change the code for this lock that is , to enable it to be opened by a different key-­card, all that will be required will be to move around the auxiliary parts, by inserting some inside the pin housing, or withdrawing others, as required by the new key.
  • a slot has been added for this purpose to the movable element of the lock, level with the upper end of the pins.
  • This slot has a setting plate incorporated, on which two holes have been made to coincide diametrically with each one of the pin housings; this plate will be enabled to adopt two extreme locations within its relevant slot, in one of which locations one of its sets of holes is axially faced with the pin housings; in the other location, it is its second set of holes which is axially implanted inside those housings.
  • said plate goes into a position in which all washers or auxiliary parts are located inside the pin housings, which present a conical or similar end that facilitates radial penetration of the washers through elastic distortion of their springs.
  • the insertion of any key causes the springs housed inside the housings facing the holes of said key to axialy move the set of elements implanted in those housings; the relevant washers are thus out of phase in respect to the slot in the setting plate.
  • the plate now moves longitudinally, and only the washers corresponding to those housings in the lock that are face to face with hole-free areas in the key are radially driven and withdrawn from the lock operative housings; the lock is thus automatically programmed for this key, which is the only one that can now open it, since the insertion of a different key would cause an excessive drop of the pins provided with a washer or auxiliary part, or to an insufficient drop of the pins lacking this washer.
  • this lock like any conventional lock of this type, is formed by the fixed element or body (1), and a movable element or body (2); a series of housings (3) have been made in the movable element (1) which are coaxially opposed to another series of housings (4), in the movable element (1).
  • Each one of this housings contains assemblies (3) and (4), a spring (5), a counterpin (6) and a pin (7); between each pin-counterpin (6)-(7) assembly, a cutting plane (8) has been established which, when in the open configuration, faces plane (9) which interrelates the fixed and movable elements, in order to allow the relative movement of these elements.
  • a slot (10) has been added at the end of housings (3)-(4) opposite to the emplacement of springs (5).
  • This slot is used for the insertion of the key or card (11), and has a stepped section (12) on its lower edge, which acts on one hand as a stop for key penetration and on the other as a means to drive the moveable element (2) to an opening situation, through the action of the key (11) itself.
  • each housing (4) contains the terminal ball (13) over which key (11) is to act when inserted, and a second counterpin (14) on which the ball rests; but, aside from these items, and as the main feature of this invention, an auxiliary part (15) may be added to the housing.
  • This auxiliary part may be a washer or similar item, which may be installed inside housing (4) or to be radially removed in order to render it inoperative.
  • the movable body (5) has a slot (16) at the level of the union plane between pins (7) and the auxiliary counterpins (14).
  • This slot has a movable plate (17), fitted to correspond with each one of the housings (4) of the movable body (2), with a pair of 18-18′ holes, whose section coincides with that of housing (4), one of which holes is capable of receiving a corresponding washer (15) and the other one capable of allowing passage through the elements established in the relevant housing (4).
  • this new key (11′) When this new key (11′) is inserted, it causes movement of a movable group installed in specific and different housings (4), concretely those facing the areas of key (11′) which do not present holes (19); a new movement of setting plate (17) towards the position shown in Figure 1 is thus produced -- to correspond specifically with the position represented in Figure 4, bringing about that a new set of washers (15′) is now radially removed from their respective housings (4), driven by plate (17) and through holes (18) of the plate in which they had previously been installed. The lock is now ready to be opened by the new key (11′) only.
  • an element may be attached to the movable body (2), concretely through its lower projection (21).
  • Such an element may be, for instance, an arm (22) which acts as a clutch on a ferrule (23), to establish connection between the square strip (24) associated with a door outer handle (25) and the square strip (26) that allows handling of this door from the inside, at any time.
  • This connection is made through the handle not shown in the Figure, in accordance with the solution foreseen to this effect in utility model 289.551, of same applicant.
  • the key (11) consists of a card with perforations on one area, which is inserted in slot (10) of the locking mechanism, and a sector (30), used as a handle.
  • This key serves as a pushing element that moves the movable body (2) by butting against the stepped area (12) in body; it also is the means of retraction for this movable element, since the card is kept locked to it through the relevant holes (19) and balls (13); elastic retraction of the balls is not feasible in order to withdraw the key, unless when holes (4) are operationally facing the corresponding holes or housings (3), at which moment the movable element (2) has recovered its primitive position with respect to the fixed element (1).
