Definitions

  • the present invention relates to a device for operating from outside a lock installed on the inner face of a door particularly an internal lock operated by an antipanic bar, according to the preamble of claim such a device is known from the document FR-A-2 581 692.
  • antipanic locks comprise a latch which protrudes from the stile of the door to engage the respective selvage of the doorjamb and is actuated by a so-called antipanic bar which is articulated to the door so that it can oscillate at right angles thereto.
  • a latch operating device comprising a handle and a pin-tumbler cylinder.
  • the aim of the present invention is to provide a device for operating a lock from the outside, particularly for a lock which is operated by an antipanic bar, which allows to obviate the above-mentioned drawbacks.
  • This aim is achieved by a device according to the appended claim 1.
  • the device comprises a case 1 which is vertically elongated and is composed of a front wall 2 which has a substantially rectangular shape and of two parallel walls 3 and 4 which are mutually connected by rounded walls 5 and 6 which delimit the compartment 7 for containing the elements of the device (see Figure 4).
  • 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 which are screwed into the bushes 8-11.
  • Threaded holes 17 and 18 are formed in the cover 12 and the threaded ends of hexagonal posts 19 and 20 (see Figure 2) for installing the device on a door 21 are screwed in said cover.
  • the device is applied to the outer face of the door 21, opposite an antipanic lock 22 installed on the inner face and provided with an operating bar 23.
  • the device is fixed to the lock 22 by means of two screws 24 and 25 which pass through the lock 22 and the door 21 and engage threaded holes of the posts 19 and 20.
  • the operative connection between the device and the lock 22 is provided by means of a rod 26 which has a square cross-section and which, when rotated by the device, activates the latch 27 of the antipanic lock 22.
  • the rod 26 has a side-fit coupling in a complementarily shaped seat 28 of a cylindrical tang 29 which protrudes from the cover 12 through a hole 30 in which it is supported so that it can rotate about the axis C.
  • the tang 29 is termed output tang of the device hereinafter (see Figures 3 and 5).
  • the tang 29 is provided with a flange 31 which rests on the inner face of the cover 12 and has a pin 32 ( Figure 5) which is eccentric with respect to the rotation axis C.
  • the pin 32 engages a U-shaped slot 33 which is formed in a plate 34 which is adjacent to the flange 31.
  • the plate 34 (see Figure 6 in particular) has a substantially rectangular shape and is guided in the direction A between the side walls 3 and 4 of the case 1 and above raised portions 35, 36 and 37 which protrude inside the compartment 7.
  • a seat 38 ( Figure 5) is formed in the raised portions 35, 36, 37, and a disk 39 can rotate therein; in turn, said disk has a cylindrical internal cavity 40 which is open toward the front wall 2.
  • the disk 39 is milled on a plane which is perpendicular to the axis C, so as to have a slot 41 which is shaped like a circular segment and interacts the internal cavity 40.
  • a hole 42 is formed in the disk 39, radially to the axis C and on the plane of the slot 41, and lies on the centerline plane of the slot 41 that passes through the axis C.
  • a flange 43 (see also Figure 8) is rotatably accommodated in the cavity 40 provided inside the disk 39, and a central stem 44 and a sector 45 protrude from said flange along the axis C.
  • the central stem 44 has an end which is rotatably coupled and inserted in a recess of a square tang 46 which is axially rigidly coupled by means of a screw 47 which engages the stem 44.
  • the square tang 46 hereinafter termed input tang, is provided with a collar 48 which is rotatably supported in a sleeve 49 which protrudes out of the front wall 2.
  • the collar 48 has an external sector 50 in which a recess 51 is provided which is complementary to the sector 45, so as to receive said sector and provide a rotary coupling between the flange 43 and the tang 46.
  • a chamber is formed between the central stem 44 and the collar 48 and accommodates a spring 52 which is wound around the central stem 44 and whose opposite ends are folded outward and rest on opposite sides of a tooth 53, which protrudes inward from the sleeve 49, and of a tab 54 which protrudes axially from the collar 48.
  • the tooth 53 and the tab 54 have the same angular breadth, so that the ends of the spring 52, by acting on both sides of the tooth 53 and of the tab 54, keep the input tang 46 elastically in a given inactive position.
  • a dead hole 56 (see Figures 5 and 8) which is slightly larger in diameter than the hole 42 of the disk 39.
  • a pin 57 having the same diameter is slidingly guided in the dead hole 56 and is provided with a spherical head 58 which has the same diameter as the hole 42, so that an annular shoulder 59 remains between the pin 57 and the spherical head 58.
  • a spring 60 is accommodated inside the dead hole 56 and actuates the pin 57 into the position in which the shoulder 59 abuts against the edge of the hole 42. In this position, the spherical head 58 engages the hole 42 and therefore rotationally rigidly couples the disk 39 to the flange 43 and therefore to the tang 46.
  • the disk 39 has a pin 61 which is eccentric with respect to the rotation axis C and is arranged, in the inactive condition, on the plane D which is perpendicular to the plane A and passes through the axis C.
  • the pin 61 engages a slot 62 ( Figure 6) which is formed on a lateral edge of the plate 34 so that the rotation of the disk 39 in one direction or the other produces the movement of the plate 34 in the direction A by an equal extent with respect to the plane D.
  • the slot 33 is composed of two portions 63 and 64 which are perpendicular to the plane A and are connected by a circular portion 65 so as to form a slot which is U-shaped and open toward the wall 3 and in which the portions 63 and 64 are equidistant with respect to the plane of the slot 62.
  • the pin 32 of the flange 31 of the output tang 29 is engaged in the portion 63 or 64, depending on whether the device must be installed on a right- or left-opening door, as described hereinafter.
  • a key 66 is engaged in the slot 41 of the disk 39 and is constituted by a T-shaped plate which is guided along the axis A between the side walls 3 and 4 of the casing 1 and the bushes 10 and 11.
  • a pin 67 (see Figure 4) is centrally fixed on the key 66 and a spring 68 is wound thereon; said spring comprises two arms which rest on the bushes 10 and 11 and tend to space the key 66 from the disk 39.
  • Two threaded holes 69 and 70 ( Figure 7) are formed in the key 66 below the pin 67 and symmetrically with respect to the plane A.
  • a pin 71 is screwed into the hole 69; however, depending on the type of right or left opening of the door, it can be screwed into the hole 70.
  • a slider 72 acts against the pin 71 and is movable at right angles to the axis A by means of a pin-tumbler cylinder 73.
  • the slider 72 is constituted by a plate in which there are two studs 74 and 75 and a slot 76.
  • the two studs 74 and 75 engage in a slot 77 which is formed in the rear face of the wall 2 at right angles to the axis A.
  • the slot 76 is crossed by a screw 78 which, together with the studs 74 and 75, guides the slider 72 in a direction which is perpendicular to the axis A.
  • the slider 72 has an extension which forms an isosceles-triangle cam 79 in which the oblique sides form two ramps 80 and 81 which converge, from the upper edge 82 and 83 of the slider, toward a flat region or hollow 84 formed at the top of the cam 79.
  • a recess 85 is formed in the lower edge of the slider 72 and is adapted to be engaged by the bit 86 of the cylinder 73.
  • the cylinder 73 is accommodated in a seat of a body 87 ( Figures 5 and 9) which is applied externally to the front wall 2 and is fixed by means of screws 88 and 89 which are inserted from the inside through the front wall.
  • the slider 72 is capable of assuming two stable positions at the right and left stroke limits.
  • a hollow 90 ( Figures 5 and 9) which accommodates a cylindrical spring 91 which acts on a ball 92, which can engage one of two holes 93 and 94 formed in the slider 72.
  • the operation of the above-described device is the same both when the device is to be installed on a right-opening door, i.e., a door in which the hinges are arranged on the right, and when the door must open to the left, i.e., has hinges arranged on the left.
  • the device can be preset so as to operate for just one type of opening.
  • the front plate 2 above and below the plate 34, two threaded holes 95 and 96 are provided, and a pin is screwed in each case in one of said holes; said pin, starting from a position in which the slot 62 lies on the axis D, prevents the stroke of the plate 34 in the direction in which the pin is arranged.
  • the pin is designated by the reference numeral 97 and is screwed in the hole 96 and therefore allows the plate 34 to move only upward. Accordingly, the disk 39 and the input tang 46 can rotate in the clockwise direction E (viewing the case 1 from the rear).
  • the pin 32 of the output tang 29 is arranged so as to engage the portion of the slot that allows the tang 29 to rotate in the same direction as the input tang 46, i.e., the portion 64 as shown in Figure 6.
  • the cover 12 in order to indicate on the outside of the case the manner in which the two pins 71 and 97 must be preset according to the door opening direction, in the cover 12 there are four openings 98, 99, 100, 101 (see Figure 3) which allow to position the pins 71 and 97 without having to remove the cover 12 and there are two notches 102 and 103 which allow to orientate a reference 104 of the output tang 29 so that the pin 32 engages the portion 63 or 64 of the slot 65.
  • the pin 32 is assumed to be engaged in the portion 64 (see Figure 6).
  • the openings 98, 101 allow to place the pins 97 and 71 in the threaded holes 95 and 70 so as to preset the device for right-opening doors.
  • the openings 95 and 70 and the notch 102 are identified by a Dx (right) symbol in order to indicate right-side opening.
  • the openings 99 and 100 allow to position the pins 97 and 71 for left-opening doors.
  • the openings 99, 100 and the notch 103 are identified by the symbol Sx (left) to indicate left-side opening.
  • the operating method of the device is as follows.
  • the pins 97 and 71 are arranged respectively in the hole 96 of the front wall 2 and in the hole 69 of the key 66, identified by Sx, and the output tang 29 is orientated so as to place the reference 104 on the Sx symbol of the cover. In this position, the pin 32 is engaged in the portion 64 of the slot 33.
  • the cylinder 73 In order to deactivate the device, i.e., to prevent the lock 22 from being operated from the outside, the cylinder 73 is operated; its bit 86, by turning in the same direction as the handle 55, i.e. clockwise, acts on the slider 72, moving it into the position in which the pin 71, after moving along the ramp 80 of the cam 79, has risen onto the flat portions 84 ( Figure 7).
  • the invention perfectly achieves the intended aim.
  • the movement of the pin 32 of the output tang 29 in the upper portion 63 of the slot 33 is performed after removing the pin 97 from the hole 96 and before said pin is screwed into the hole 95.
  • the plate 34 can thus slide freely and the pin 32 can move along the arc-like portion 65 of the slot 33 in order to engage in the upper portion 63.
  • the pin 32 engages the end of the portion 63 or 64 that lies opposite to the ends joined by the arc-like portion 65, and that the radius of the pivot 32 from the rotation axis C of the output tang 29 is greater than the stroke of the plate 34 up to the abutment against the pin 97. In this manner, the pin 32 cannot oscillate to return to the arc-like portion 65 and remains rigidly coupled to the selected portion 63 or 64 of the plate 34.
