Definitions

  • the present invention relates to a padlock.
  • padlocks are known that are constituted by a metal body, with a typical substantially parallelepiped conformation, the top surface of which is provided, along two axes that are approximately mutually parallel, with a first and a second seat, that are substantially cylindrical, within which a substantially cylindrical first arm and second arm respectively, of an upside-down U-shaped metal bow are slidingly associated, (see for example US-B1-7076976 ).
  • the first arm of the bow is longer than the second arm, in such a way that the second arm can be inserted or extracted axially from the second seat, while simultaneously maintaining the first arm inserted in the first seat.
  • the first arm of the metal bow further rotates into the first seat, and can translate longitudinally to the first seat between an internal end position and an external end position, delimited when reaching an adapted end tooth, which protrudes from the internal surface of the first seat, with the transversal ends of a suitable groove that is provided longitudinally on the lateral surface of the first arm.
  • a first spring is usually interposed between the bottom of the first seat and the first arm and is adapted to force such first arm towards the external end position.
  • such second arm can be retained within the second seat by way of an adapted locking tooth that is slidingly accommodated within a cavity that is provided, transversally to the second seat, in the metal body.
  • the locking tooth is forced toward the second arm by the action of a second spring that is interposed between the locking tooth and the bottom of the cavity; such locking tooth, when pushed by the second spring, is inserted within a suitable third seat formed in the facing lateral surface of the second arm, thus preventing its removal from the second seat, and therefore maintaining the padlock in the closed condition.
  • the locking tooth is connected to an eccentric that is made to move by way of the reel of a lock inserted in the metal body and is actuated by way of an adapted key.
  • the first arm of the bow may then be inserted, for example, in two links of a chain to be mutually joined, and may thus be fixed again in the first seat, thus coupling detachably such links to each other and to such arm.
  • Such padlock of a known type has, however, a drawback; in fact the lock is accessible from the outside, and therefore is exposed to possible tampering or acts of vandalism including, for example, the introduction, through the key access slit, of glue or other substances that could damage the reel.
  • the lock is exposed to atmospheric agents such as, for example, rain or snow that put the lock at risk of oxidation and/or deterioration.
  • the aim of the present invention is to solve the technical problems mentioned, eliminating the drawbacks of the known cited art, by providing a padlock that reduces the risk of its unauthorized opening and tampering.
  • an object of the invention is to provide a padlock that can be exposed to atmospheric agents such as, for example, rain or snow reducing the risk of becoming damaged or deteriorating.
  • Another object of the invention is to provide a padlock that is structurally simple and with low manufacturing costs.
  • a padlock comprising a body in which a first seat is provided, to which a pivot is slidingly associated, said body and pivot being shaped in such a way so that together they form a ring that can be selectively opened and closed by way of the sliding of the pivot with respect to the body, characterized in that in said body a cavity is formed, that is arranged transversally to said first seat and communicates with it, to which a pin is slidingly associated which is adapted to abut against a first groove, that is formed within said pivot, to temporarily block the sliding of said pivot with respect to said first seat in the condition in which the padlock is closed, one or more appendages protruding approximately radially from the lateral surface of said pin and interacting with one or more cams that are rotatably associated within said body and that selectively interact with magnetic means that are adapted to selectively modify the position of said cams in order to either lock or allow said pin to slide within said cavity, and respectively
  • the reference numeral 1 designates a padlock comprising a body 2, made of metal, in which a first seat 3 is provided with which a pivot 4, advantageously made of steel, is slidingly associated.
  • the body 2 and the pivot 4 are shaped in such a way so that together they form a ring, which can be selectively opened and closed by way of the sliding of the pivot 4 with respect to the body 2.
  • the body 2 is, advantageously, in a front view, almost U-shaped, with a first base 5 that is preferably approximately parallelepiped and from which a first branch 6 and a second branch 7 respectively protrude that are substantially parallelepiped and about mutually parallel.
  • the first seat 3 is provided within the first branch 6, beginning from the surface of the first branch which faces the second branch 7, and is blind and preferably approximately cylindrical.
  • the second branch 7 is provided with a second seat 8 that has, in a transverse section, the same shape as the first seat 3, and is provided according to the same axis: in the embodiment shown in Figures 1 through 6 , the second seat 8 is thus substantially cylindrical and is further completely open.
  • the pivot 4 is substantially rectilinear, has a length that exceeds the distance between the first and second branches of the body 2 and, in a transverse section, is substantially shaped to complement the first and second seats, and is therefore substantially cylindrical in shape; the pivot 4 can therefore be arranged in the second seat 8 and, simultaneously inserted with its front end 4a in the first seat 3, thus forming along with the body 2, a closed ring, as shown for example in Figure 1 .
  • the pivot 4 can further be made to slide longitudinally with respect to the second seat 8, until its front end 4a comes out of the first seat 3 so as to form, along with the body 2, an open ring, as shown for example in Figure 2 .
  • the body 2 is instead provided with a substantially parallelepiped conformation, and is provided, on its top surface, with a first seat 3 and a second seat 8, both of which are substantially cylindrical in shape and about mutually parallel.
  • the pivot 4 in this case, has a transverse section that is substantially circular in shape, has a diameter that is slightly inferior to those of the first and second seats, and has in plan view an approximately upside-down U shape, so as to form a bow that is provided with a second base 9, with an arched profile, from which a first arm 10 and a second arm 11 protrude, which are substantially mutually parallel, and are slidingly and rotatably associated respectively within the first and second seats of the body 2.
  • the first arm 10 has a length higher than the second arm 11 so that the second arm can be inserted or axially extracted from the second seat 8, while simultaneously maintaining the first arm 10 inserted in the respective first seat 3.
  • the pivot 4 and the body 2 together constitute, also in this case, a ring that can be selectively opened and closed by way of the sliding of the pivot 4 with respect to the body 2.
  • the body 2 is provided with a cavity 12 that is arranged transversally to the first seat 3 and communicates therewith, and to which a pin 13 is slidingly associated that is adapted to abut an adapted first groove 14 provided within the pivot 4 in order to temporarily block the sliding movement of the pivot with respect to the first seat 3, in the condition in which the padlock is closed.
  • the cavity 12 has a substantially cylindrical conformation; the pin 13 is substantially shaped to complement the cavity 12, and therefore such pin has also a substantially cylindrical conformation, with the front end 13a, which faces the first seat 3, suitably rounded.
  • the pin 13 is forced towards the first seat 3 by way of first elastic means constituted, for example, by a first helical spring 15 interposed between the pin 13 and the bottom of the cavity 12, or an adapted first cap 16 for closing such cavity.
  • first elastic means constituted, for example, by a first helical spring 15 interposed between the pin 13 and the bottom of the cavity 12, or an adapted first cap 16 for closing such cavity.
  • the first groove 14 is annularly provided within the lateral surface of the pivot and has, in a cross-section taken along a longitudinal median plane with respect to such pivot, a flared conformation that is preferably about an isosceles trapezium or an isosceles triangle in shape, so as to form a first inclined plane 17 that is adapted to push the pin 13 away from the pivot 4 during the sliding of the pivot in the direction of its coming out from the first seat 3.
  • the front end 4a of the pivot 4, beginning from the first groove 14, is substantially troncoconical in shape, so as to form a second inclined plane 18, that is adapted to push the pin 13 away from the pivot 4 during the sliding of such pivot in the direction of its insertion in the first seat 3.
  • One or more appendages 19 protrude approximately radially from the lateral surface of the pin 13, and are preferably cylindrical or prismatic in shape, and are substantially mutually parallel and are mutually aligned according to a generatrix of the pin 13.
  • the appendages 19 interact with one or more cams 20 that are substantially cylindrical in shape and are rotatably associated within the body 2 and selectively interact with magnetic means that are adapted to selectively modify the position of such appendages in order to block or allow the sliding movement of the pin 13 into the cavity 12, and thus to block or unblock respectively the sliding movement of the pivot 4 with respect to the first seat 3.
  • the cams 20 are rotatably accommodated within adapted third seats 21, which are substantially cylindrical in shape, and are provided on the bottom of a slot 22, that preferably has an approximately rectangular plan shape, and is provided within the body 2; advantageously, the third seats 21 are arranged so that their longitudinal axes are about mutually parallel and mutually aligned approximately according to the longitudinal median axis of the pin 13.
  • the cams 20 are kept within the respective third seats 21 by way of first caps 23 that at least partially have a plan shape that complements the third seats 21 in order to be fixed by pressure therein.
  • the first caps 23 are in turn covered by a second cap 24 that has a plan shape that complements the slot 22, and is fixed therein and positioned at the desired distance from the perimeter's edge of such slot.
  • a cut-out portion 25, that preferably but not necessarily has an approximately semi-circular plan shape, is provided on the lateral surface of the cams 20, along a generatrix and beginning from the surface of the cams which faces the pin 13, and one of the appendages 19 may be accommodated therein.
  • said magnetic means comprise one or more first magnets 26, which are associated in a suitable position with respect to the cams 20.
  • Such magnetic means moreover, comprise an adapted magnetic key 27 comprising a plate 28, that at least partially has a plan shape that partially complements the slot 22, so that it can be positioned partially within such slot, resting on the second cap 24.
  • one or more small disks 29 are arranged on the plate 28 and one or more second magnets 30 are associated therewith that are adapted to magnetically interact with the first magnets 26 of the cams 20, in the condition in which the plate 28 is positioned on the second cap 24, so as to cause the desired rotation of such cams 20.
  • the mutual position of the first and second magnets is such that, in the condition in which the plate 28 is positioned on the second cap 24, the through holes 25 of the cams 20 are all facing towards the first seat 3 and are mutually aligned approximately along the longitudinal median axis of the pin 13, so that the appendages 19 can be inserted in such through holes 25, and the pin 13 is free to slide within the respective cavity 12, thus freeing the sliding movement of the pivot 4 and allowing the padlock 2 to open.
  • the position of the first magnets 26 with respect to the cams 20 univocally defines the position where the second magnets 30 of the disks 29 should be positioned with respect to the plate 28 of the magnetic key 27 in order to allow the padlock 2 to be opened; therefore only one magnetic key 27 is associated with each configuration of the first magnets 26 and the cams 20.
  • the magnetic key 27 further comprises a third cap 31 that is hinged to the plate 28 and is adapted to close the disks 29.
  • the padlock 1 comprises retaining means that are adapted to prevent the separation of the pivot 4 from the body 2.
  • such retaining means advantageously comprise a locking pin 32 that is slidingly associated with a fourth seat 33, formed within the body 2, transversally to the second seat 8 and communicating therewith; the locking pin 32 is forced against the lateral surface of the pivot 4 by way of second elastic means that are constituted, for example, by a second helical spring 34 that is interposed between the bottom of the fourth seat 33 and the locking pin 32.
  • a slot 35 is provided on the lateral surface of the pivot 4 in which, when it is positioned at the fourth seat 33, the locking pin 32 enters, by the action of the second helical spring 34, thus preventing the further sliding movement of the pivot 4 away from the first seat 3.
  • a third inclined plane 36 is formed that is adapted to push the locking pin 32 towards the bottom of the fourth seat 33 during the sliding movement of the pivot 4 towards the first seat 3.
  • such retaining means are constituted by an abutment element 37, for example a pin, that radially protrudes from the lateral surface of the first seat 3 and is adapted to abut, with its two ends, against a second groove 38 that is provided annularly on the pivot 4, so as to limit the sliding movement of such pivot with respect to the first seat 3.
  • abutment element 37 for example a pin
  • the appendages 19 abut with the lateral surface of the cams 20, preventing the pin 13 from translating away from the pivot 4; thus the front end 13a of the pin 13 remains inserted in the first groove 14, and prevents the pivot 4 from sliding with respect to the first seat 3, maintaining the padlock 4 in the closed condition.
  • the second magnets 30 of the magnetic key 27 magnetically mate with the first magnets 26 of the cams 20 and thus induce the rotation of such cams until all the through holes 25 of the cams 20 face towards the first seat 3 and are mutually aligned approximately according to the longitudinal median axis of the pin 13.
  • the pin 13 can translate away from the pivot 4 because the appendages 19 that protrude from such pin can be inserted within the through holes 25 of the cams 20.
  • the invention described achieves the intended aim and objects, providing a padlock that, in the closed condition, has no parts that are accessible from the outside, including for example a keyhole, and thus reduces the risk of unauthorized opening or tampering of such padlock.
  • the padlock according to the invention allows the padlock according to the invention to be exposed to atmospheric agents, including from example rain or snow, reducing the risk of damage or deterioration of such padlock.
  • the manufacturing costs of the padlock according to the invention are low, as it is provided solely with components that are easily manufactured and/or assembled.
