Definitions

  • the present invention relates to a lock with a device for selecting the actuation direction of said lock according to the door side whereon it is installed as detailed in the preamble of appended claim 1.
  • the aim of the present invention is to provide a device which allows to select the actuation direction of a lock by acting without having to open the lock.
  • 1 designates the case of the lock.
  • Said case 1 is vertically elongated and is composed of a substantially rectangular front wall 2 and of two parallel walls 3 and 4 which are mutually connected by rounded walls 5, 6 which delimit the compartment 7 for containing the elements of the device (see Figure 2).
  • the letters A and B also designate the vertical and horizontal directions.
  • the cover 12 rests on the bushes 8-11, closes the compartment 7 to the rear, and is fixed by screws 13, 14, 15, 16 screwed into the bushes 8-11.
  • Threaded holes 17, 18 are formed in the cover 12 and the threaded ends of screws for fitting the lock to a door are screwed into said holes.
  • the operating connection between the lock and a door locking element is provided by means of a rod, not shown, which has a square cross-section and which activates the locking element when it is turned by the lock.
  • the rod is coupled with a side fit in a complementarily shaped seat of a cylindrical shank 19 which protrudes from the cover 12 through a hole 20 in which it is supported so that it can rotate about the axis C.
  • the shank 19 is termed output shank of the lock hereinafter.
  • the shank 19 has a flange 21 which rests on the internal face of the cover 12 and has a pin 22 ( Figure 3) which is eccentric with respect to the rotation axis C.
  • the pin 22 engages a U-shaped slot 23 formed in a plate 24 which is adjacent to the flange 21.
  • the plate 24 (see Figure 2 in particular) is substantially rectangular and is guided in the direction A between the side walls 3, 4 of the case 1 and above raised portions 25, 26, 27 which protrude inside the compartment 7.
  • a flange 31 is rotatably accommodated in the cavity 30 inside the disk 29, and a central stem 32 and a sector 33 protrude from said flange along the axis C.
  • the central stem 32 has an end which is inserted in, and rotationally coupled to, a recess of a square shank 34 which is fixed axially by means of a screw 35 which engages the stem 32.
  • the square shank 34 hereinafter termed input shank, is provided with a collar 36 which is rotatably supported in a sleeve 37 which protrudes outside the front wall 2.
  • the collar 36 has an external sector 38 in which a recess 39 is formed; said recess is shaped complementarily with respect to the sector 33 in order to receive it so as to provide a rotary coupling between the flange 31 and the shank 34.
  • a chamber is formed between the central stem 32 and the collar 36 in which a spring 40 accommodates, which is wound around the central stem 32 and whose opposite ends are folded outward and rest on opposite sides of a tooth 41 ( Figure 3) which protrudes inward from the sleeve 37 and of a tab 42, respectively (see also Figure 1), which projects axially from the collar 36.
  • the tooth 41 and the tab 42 have the same angular breadth, so that the ends of the spring 40, by acting on both sides of the tooth 41 of the tab 42, keep the input shank 34 elastically in a given inactive position.
  • a dead hole 44 is formed in the flange 31 (see Figure 3) and a pin 45 is slidingly guided therein; said pin is actuated by a spring 46 so that it engages in a hole 47 of the disk 29 and provides a rotary coupling between the input shank 34 and the output shank 19.
  • a mechanism which is generally designated by the reference numeral 48 and actuated by the bit of a pin-tumbler cylinder 48a, is provided.
  • the disk 29 has a pin 49 which is eccentric with respect to the rotation axis C and which, in the inactive condition, is arranged on the plane D, which is perpendicular to the plane A and passes through the axis C.
  • the pin 49 is engaged in a slot 50 ( Figure 4) formed on a lateral edge of the plate 24, so that the rotation of the disk 29 in either direction causes the movement of the plate 24 in the direction A by an equal extent with respect to the plane D.
  • the slot 23 is composed of two portions 51, 52 which are perpendicular to the plane A and are connected by a circular portion 53 so as to produce a U-shaped slot which is open toward the wall 3 and has portions 51, 52 which are equidistant with respect to the plane of the slot 50.
  • the pin 22 of the flange 21 of the output shank 19 engages the portion 51 or 52, depending on whether the lock is to be installed on a door which opens on its right or left side, as described hereinafter.
  • the operation of the above-described lock is the same both when the lock is to be installed in a door opening on its left side, i.e., in a door in which the hinges are arranged to the right, and when the door opens is to the right, i.e., has hinges arranged to the left.
  • the device can be preset so that it operates only for one type of opening.
  • the front plate 2 above and below the plate 24, there are two threaded holes 54, 55, in one of which an abutment pin is screwed in each instance; starting from a position in which the slot 50 lies on the axis D, said pin prevents the stroke of the plate 24 in the direction in which the pin is arranged.
  • the pin is designated by the reference numeral 56 and is screwed into the hole 54 and therefore allows the plate 24 to move only downward. Accordingly, the disk 29 and the input shank 34 can rotate in the counterclockwise direction E (viewing the case 1 from the rear).
  • the pin 22 of the output shank 19 is arranged so as to engage the portion of the slot that allows the shank 19 to rotate in the same direction E as the input shank 34, i.e., the portion 51 as shown in Figure 4.
  • the cover 12 in order to indicate outside the case the manner in which the pin 56 must be arranged according to the door opening side, in the cover 12 there are two openings 57, 58 (see Figure 1) which allow to place the pin 56 without having to remove the cover 12 and there are two notches 59, 60 which allow to orientate a reference marking 61 of the output shank 19 so that the pin 22 engages the portion 51 or 52 of the slot 23.
  • the opening 57 of the cover allows to place the pin 56 in the threaded hole 54, so as to preset the device for doors opening on the right side.
  • the opening and the notch 59 are identified by a symbol Dx (right) in order to indicate right-side opening.
  • the opening 58 allows to position the pin 56 for doors which open on the left side.
  • the opening 58 and the notch 60 are identified by the symbol Sx (left) to indicate left-side opening.
  • the operating method of the device is as follows.
  • the pin 56 is placed in the hole 54 of the front wall 2 that is marked with Dx and the output shank 19 is orientated so as to place the reference marking 61 on the symbol Dx of the cover. In this position, the pin 22 is engaged in the portion 51 of the slot 23.
  • the pin 22 of the output shank 19 moves into the lower portion 52 of the slot 23 after removing the pin 56 from the hole 54 and before screwing it into the hole 55.
  • the plate 24 can thus slide freely and the pin 22 can move along the arc-like portion 53 of the slot 23 in order to engage the lower portion 52.
  • the pin 22 engages the end of the portion 51 or 52 which is opposite to the ends connected by the arc-like portion 23, and that the radius of the pin 22 with respect to the rotation axis C of the output shank 19 is greater than the stroke that the plate 24 performs until it abuts against the pin 56. In this way, the pin 22 cannot oscillate to return into the arc-like portion 53 and remains rigidly coupled to the selected portion 51 or 52 of the plate 24.
  • the plate 24 acts as an increasing or reducing element for the rotation of the output pivot 19.
  • the distance between the portions 51 and 52 it is in fact possible, for an equal angular movement of the eccentric pin 49, to vary the stroke of the pin 22 in the direction A and therefore vary the rotation angle of the output shank 19.
  • an angular rotation of 45° of the input shank 34 and therefore of the disk 29 it is possible to achieve a 90° rotation of the output shank 19.
