Definitions

  • the present invention relates to a lock provided with a gear device for actuating at least one bolt for closing a door, window and the like.
  • the bolt is actuated into the open and closed position by means of a gear which meshes with a pinion which is shaped like a toothed ring having a radial slot and suitable to be turned by the bit of a cylinder which is driven through said pinion.
  • the radial slot of the pinion is explained by the fact that the pinion is usually already provided in the lock and that it must be possible to insert the cylinder in the lock only at a later time, when the lock has already been installed in the door, so that the bit can replace the missing tooth of the pinion at the radial slot.
  • the cylinder has standard dimensions and the bit is thinner, in a tangential direction, than the dimensions of the cylinder, it is not possible to maintain a constant space between the bit and the adjacent teeth of the pinion.
  • the drawback arises that the bit, once the cylinder has been inserted in the lock, has a certain play in the radial slot of the pinion. This play compromises the meshing of the bit with the gear to be turned.
  • the aim of the present invention is to provide a lock having a device of the described type which is structurally simple and therefore economically more advantageous than conventional ones and is highly reliable in operation.
  • a lock provided with a gear device for actuating at least one bolt for closing a door, window and the like, comprising a gear which is operatively associated with said bolt and a pinion which meshes with said gear, said pinion having a slot which lies radially between two teeth and is formed by two side walls between which the bit of a cylinder is arranged with play, said cylinder being inserted in the lock through said pinion, said bit forming, together with said side walls of the slot, two interspaces which are arranged upstream and downstream of said bit with respect to the direction of rotation of said bit; characterized in that said gear has at least one pair of adjacent teeth which form a tooth space which can be engaged by said bit at each turn of the pinion and are shaped so that the tooth of said pair that engages the interspace arranged downstream of the bit produces, during the rotation angle in which said tooth remains engaged in said interspace, the approach and abutment of said bit against the side wall arranged downstream of it.
  • the lock comprises a case 1 which is composed of a bottom 2 from which an upper wall 3, a lower wall 4 and a front wall 5 rise.
  • a front faceplate 6 is associated with the front wall 5 in order to fix the lock in the seat of a door.
  • the lock comprises a gear device, generally designated by the reference numeral 11, which is capable of making the bolt 8 and the plate sliders 9, 10 move for protruding from the case 1 and retracting into it depending on whether the lock must open or close the door.
  • the device 11 comprises a prism-shaped block 12, which is fixed to the bottom 2 of the case 1 proximate to the lower wall 4.
  • a through opening 13 is formed in the prism-shaped block 12 and its cross-section is complementary to the cross-section of a lock with a lock actuation cylinder 14, termed simply "cylinder" hereinafter for the sake of convenience in description.
  • the cylinder 14 is of a standard type with a cylindrical portion 15, in which the bit 16 is supported in a median region so that it can rotate about the axis A and from which a longitudinal ridge 17 protrudes radially.
  • the opening 13 is aligned with openings 18 and 19 which have the same shape and are formed in the bottom 2 and in the cover 20 which closes the case in a front region.
  • a seat 21 is formed in the block 12, is closed by a lamina 22 and accommodates a pinion 23 which can rotate about the rotation axis A of the bit 16 of the cylinder 14.
  • the pinion 23 is composed of a ring 24, in a front region of which teeth 25 are provided which are radial with respect to the axis A; their cross-section, on the plane that lies at right angles to the axis A, is substantially rectangular.
  • the ring 24 surrounds an opening which is identical to the openings 13, 18 and 19, i.e., has a circular central portion 26 which is suitable to receive the cylindrical portion 15 of the cylinder 14 and a radial slot formed between two walls 27 and 28 whose distance is equal to the thickness of the ridge 17 of the cylinder 14.
  • the height of the teeth 25 is less than the axial length of the bit 16 in the direction of the axis A. In this manner, the bit 16 always remains between the lamina 22 and the bottom of the seat 21 and the walls 27 and 28 of the radial slot of the pinion 23.
  • the bit 16 has a thickness, i.e., a width in the direction of its rotation, which is smaller than the thickness of the ridge 17 of the cylinder 14. Accordingly, after the cylinder 14 has been inserted in the case 1 of the lock and placed so that the bit 16 lies between the walls 27 and 28 of the pinion 23, between the walls 27 and 28 and the bit 16 a play remains which, together with the adjacent teeth arranged upstream and downstream of the pinion, helps to form two interspaces 29 and 30, whose width can vary according to the direction of rotation of the bit. In any case, through the actuation of the cylinder the interspace arranged downstream of the bit always covers a smaller angle than the interspace arranged upstream of the bit.
  • the pinion 23 transmits the movement to the bolt 8 and to the plates 9 and 10 by means of a gear train composed of a gear 31 which is rotatably supported in the case 1 and meshes with the pinion 23.
  • the gear 31 has two teeth 32 and 33 provided with mutually opposite fronts which are chamfered so that the teeth assume the configuration of two diverging protrusions and the tooth space 34 formed between them is flared outward.
  • the gear 31 has a number of teeth such that at each turn of the pinion 23 the bit 16 engages the tooth space 34. In practice, therefore, the number of teeth of the gear 31 is equal to, or an exact multiple of, the number of teeth of the pinion 23, counting the bit as a tooth.
  • a sprocket 35 is rotationally rigidly coupled to the gear 31 and, by means of a pair of gears 36 and 37, it is connected to a gear set 38 which is rotatably supported on a pivot 39 locked between the bottom 2 and the cover of the case.
  • the gear set 38 comprises a gear 40, which has a larger diameter and meshes with the gear 37, and a gear 41, which is rotationally rigidly coupled to the gear 40 and meshes with a gear 42 arranged between the bolt 8 and the cover 20.
  • the gear 42 is rotatably supported in the cover 20 by means of a pivot 43 and has, on the face directed toward the cover 20, two diametrically opposite pins 44 and 45 which are suitable to engage slots 46 and 47 (see Figure 1) of the sliders 9 and 10 and, on the opposite face, a pin 48 which engages a slot 49 formed in the bolt 8 transversely to its sliding direction.
  • the cylinder 14 is inserted through the openings 13 of the body 12, the openings 18 and 19 of the bottom 2 and of the cover 20, and the pinion 23, so that the bit 16 is interposed between the walls 27 and 28 which form the radial slot of the pinion.
  • the cylinder 14 is then fixed in a conventional manner by means of a screw which is driven through the faceplate 6 and engages a threaded hole 50 of the ridge 17 of the cylinder at the bit 16.
  • the pinion 23 turns and, by meshing with the gear 31, transmits this rotation to the gear train 35-42, causing the outward sliding, into the position for locking the door or window, of the bolt 8, of the sliders 9 and 10 and of the bolts connected thereto.
  • the interspace 29 is smaller than the interspace between the teeth 25, when the bit 16 has turned through an angle of approximately 120° (see Figure 4) and is about to mesh with the gear 31, the teeth of said gear would no longer be able to engage the interspace 29.
  • the shape of the tooth 32 allows said tooth to fit in the interspace 29 and momentarily space the bit 16 from the wall 28 (see Figure 5). The bit can thus engage the tooth space 34 that lies between the teeth 32 and 33 and turn the gear 31.
  • the sides of the teeth 32 and 33 that delimit the tooth space 34 are shaped so that in addition to facilitating the insertion of the tooth 32 in the interspace 29 the bit 16 is guided until it rests against the wall 28 (see Figure 6).
  • the bit 16 performs a forward angular movement which widens the interspace 30 arranged upstream of it, allowing to insert the tooth 33 in the preceding interspace 30 and allowing the pinion 23 to mesh again with the gear 31 (see Figure 7) in order to continue its rotation and therefore also complete the rotation of the gear 31.
  • the gear 31 can have a number of teeth which is a multiple of the teeth of the pinion 23, so as to have a multiple number of pairs of shaped teeth 32 and 33 which allows the bit 16, at each turn of the pinion 23, to engage between a pair of shaped teeth.
