Definitions

  • the invention relates to an external unit for controlling access via doors with a lock which can only be operated from inside.
  • the external unit is one which is actuated by means of a combination cylinder which is operated by means of a key, to make it possible for a door, which is fitted with a lock, which is designed to only be opened from inside, to also be opened from outside, though only by someone who has the said key which can be used to block the said access from outside without affecting the opening of the door from the inside which can occur at any time.
  • a typical example is that of emergency doors which are provided, on the inside, with anti-panic bars which actuate the opening of the lock to enable the escape of persons (as in large commercial areas, hospitals, sporting and cultural precincts, factories, etc.).
  • the external unit can generally be applied in all cases where there is a door which is basically provided as an exit, but where, without affecting opening from inside, doors are also able to be opened occasionally from the outside by whoever has the key to do so.
  • the new exterior unit which is now proposed, seeks to provide a device for which the assembly of the combination cylinder is extremely simple, enabling simple and quick substitution.
  • an exterior unit for controlling access via doors with a lock which can normally only be operated from the inside, comprising a combination key cylinder to prevent or enable access from the exterior, a fixed support housing in which the combination cylinder is insertable from the front of the exterior unit, by sliding it longitudinally into the support housing, a sliding catch incorporated in the support housing and co-operating in the inserted position of the cylinder, with an aligned transverse cavity which is provided in at least one side of the housing of the combination cylinder and into which the tip of the said catch is slideable to retain the combination cylinder, a spring for urging the catch into its locking position, the catch having, at the rear, a conical tail which is axially guided in a chamber of the support housing and which has a radial threaded hole which is accessible from the back of the exterior unit, and a grub screw, which has a conical tip which is complementary to the conical form of the conical tail, located in this threaded hole, the grub screw being screwable between
  • this mounting can take place with the grub screw in its protruding position in which it retains the conical tail element of the catch.
  • This invention also seeks to provide a simple, economic and efficient mechanism which, through actuation of the cylinder (by the combination key), is able to lock the handle with which the proposed external unit is fitted.
  • the mechanism consists in that, when turning the key, of the combination cylinder, in the opening direction, the rotational movement of the projection of this acts on one or other of the first radial faces of a tilting cam element which is symmetrical in relation to the vertical plane which contains the virtual axis of the said combination cylinder, the tilting cam element forming, an upwards, obtuse, re-entrant angle which, by through each apex, connects with respective retention sides, the tilting cam element taking up an untilted position, with its plane of symmetry being vertically aligned, and a tilted position in which one of the two apices abuts against a side of the said exterior unit and the other apex slightly extends beyond the said vertical plane containing the virtual axis of the combination cylinder, and a sliding engaging plate, which is guided vertically and has a lower obtuse angular projection, which corresponds to the re-entrant angle of the tilting cam element, engaging the
  • this mechanism is that the projection of the cylinder tilts the tilted cam element, and, inclined by direct action between the re-entrant of this cam element and the projection of the sliding engaging plate, this engaging plate rises until the straight, vertical part of its window is engaged with the flats of the rotating shaft housing to which the handle is connected, such that this handle cannot turn. In this situation, the engaging plate cannot descend, because the tilting cam element has reached its point of maximum tilting in which the lower, angular projection of the engaging plate now rests on a side of this tilting cam element such that it pushes this cam element to its extremity of tilting.
  • the projection of the cylinder engages the second radial face, and the tilting cam is forced to tilt in the opposite direction, towards the initial position in which the engaging plate descends, pushed by its spring and by the force of gravity acting on it, until it becomes re engaged between the projection and angular re-entrants.
  • the symmetrical design of the tilting cam element enables functioning in both directions of rotation of the cylinder, in order to enable use of the unit in doors opening either to the left or to the right.
  • the invention also seeks, in a better embodiment thereof, to provide a highly simple and economic mechanism for rotationally actuating a shaft housing of the external unit which is connected to the opening mechanism of the interior lock of the door, by means of the combination cylinder, but without this shaft housing of the exterior unit having an operating handle.
  • this new mechanism is that, when turning the key of the combination cylinder, in the opening direction, the rotational projection of the latter engages one or the other of two impelling parts which are disposed symmetrically in relation to the initial idle position of the rotational projection, the impelling parts belonging to a sliding thrusting means which is guided vertically and which, on its upper part, incorporates a thrusting arm-piece which is positioned in a neck which is formed in the rim of a draw-plate which rotates together with a shaft housing without an external actuating handle and which has a transmission shaft, which can be connected to the opening mechanism of the said interior lock of the door, coupled to it.
  • the exterior unit (1) is actuated by means of a combination cylinder (2) which is operated by a key, and is provided with a rotating shaft housing (14) which is rotationally connected with the action of opening the interior lock of the door and which may or may not have an operating handle (19) connected on the outside.
  • a combination cylinder (2) which is operated by a key
  • a rotating shaft housing (14) which is rotationally connected with the action of opening the interior lock of the door and which may or may not have an operating handle (19) connected on the outside.
  • the exterior unit (1) will be fitted with an outer handle (19) which can be rotationally locked/unlocked by means of the key, depending on whether one wishes to prevent or allow access from outside as figures 6, 7 and 10 to 15 show.
  • the handle (19) is omitted from the exterior unit (1).
  • the turning of the key locks or unlocks the turning of the handle (19).
  • the key is used to effect the turning, of the rotating shaft housing (14), which rotation is transmitted to the mechanism which opens the interior lock, as shown by figures 8,9 and 16 to 19.
  • a first characteristic of the exterior unit (1) is the mounting of the combination cylinder (2) in the exterior unit (1) (figures 1 to 5).
  • This combination cylinder (2) is mounted from the front (1a) of the exterior unit (1), by sliding it longitudinally in a support housing (3) which is fixed and which incorporates a catch (4).
  • the catch 4, in the operating position of the combination cylinder (2), is axially opposite a corresponding transverse cavity (5) which is provided in at least one side of the elastic body of the combination cylinder (2) and which has a transverse section which has sliding adjustment in relation to that of the tip of a said catch (4).
  • the catch has two positions in one of which it retains the combination cylinder (2), and in the other of which it releases the combination cylinder (2), these positions being determined, respectively, by the compression and release of a spring (6) associated with a said catch (4).
  • This catch (4) incorporates, at the rear, a conical tail (7) which is axially guided in an enclosure (3a) of the support housing (3) and which is faced, in a radial direction, by a threaded hole (8) which is accessible from the back (1b) of the exterior unit (1).
  • the catch (4) and its conical tail element (7) are forced (figure 4) by the spring (6) into the retracted position of non-retention, in which the combination cylinder (2) can be inserted or withdrawn from the front (1a) by a simple axial sliding operation in relation to the support housing (3).
  • the grub screw (9) is only accessible from the back section (1b) and is therefore inaccessible when the outer unit (1 ) is fixed to the door from the inner side thereof.
  • the tilting cam element (10) forms an upwardly, extending obtuse, re-entrant angle (10b) which, by means of each apex (10c), is connected to respective retention sides (10d), the said tilting cam element (10) being movable between an untilted position, with its plane of symmetry being vertically aligned, and a tilted position in which one of the two apices (10c) abuts against a side (1c) of the said exterior unit (1) and the other apex (10c) slightly extends beyond the vertical plane containing the virtual axis of the combination cylinder (2).
  • a window (13) is formed by a circular part (13a) which merges below with a straight vertical part (13b), the circular part (13a) having a diameter greater than that of a rotatable shaft housing (14) to which, directly or indirectly, an external handle (19) is connected, and in this way, a transmission shaft (15) of any suitable kind which can be connected to the mechanism for opening the internal lock of the door, can be connected.
  • the straight, vertical part (13b) has a width which is more than the distance between two opposite, parallel flats (14a) of the revolving shaft housing (14), the engaging plate taking up both a lower locking position, and an upper non-locking position, these two positions corresponding, respectively, to the untilted and tilted positions of the tilted cam element (10).
  • the obtuse angular projection (12a)) is coupled with the corresponding re-entrant, obtuse angle (10b) and the said circular part (13a) of the window (13) is coaxial with the rotating shaft housing (14).
  • the said obtuse, angular projection (12a) has its vertex supported against one of the respective two retaining sides (10d) and the straight, vertical part (13b) of the window (13) is engaged with the flats (14a) of the rotatable shaft housing (14).
  • the shaft housing (14) can rotate freely in the circular part (13a) of the window (13) of the engaging plate (12).
  • the flats (14a) are positioned between the edges of the straight, vertical part (13b) of the window (13), and the rotatable shaft (14) cannot turn, so that neither can the rotating handle (19) turn; the raising of the engaging plate (12) is produced by the action of an inclined surface between the re-entrant angle (10b) and projecting angle (12a), when the tilting cam element (10) is tilted.
  • the angular projection (12a) falls on the retaining side (10d) and facilitates the movement of the tilting cam element (10) against its abutment on the side (1c) of the exterior unit (1).
  • the exterior unit (1) In the non-tilted position of the tilting cam element (10), there is a pin (16) which is attached to the body of the exterior unit (1) and which engages one of the two retaining sides (10d) which is in a rear position in relation to the direction of tilting of the said tilting cam element (10) and which is produced by opening movement being exerted on the combination cylinder (2).
  • the exterior unit (1) is provided with two of these pins (16) in symmetrical positions, and one of these, the one which is not necessary for the given right or left hand side of the door into which it is installed, is removed.
  • connection between the handle (19) and the shaft housing (14) is destructible should a force be applied, to a handle concerned, which is above a predetermined security value, such that the handle (19) becomes loose, before the interior lock can be opened or damaged, acting as a 'mechanical fuse' in the event of undue handling or of vandalism, destroying the handle which is simple and inexpensive to replace, while other mechanisms which are more costly and sensitive, are maintained.
