  • a locking device 10 includes a pair of end pieces 12, 14 and a locking member or rod 16 (FIGS. 1 and 2).
  • End piece 12 receives one end 16a of rod 16 therein, while end piece 14 is configured to receive the other end 16b of rod 16 therein when rod 16 is inserted through an object to lock the locking device to the object, which may be a door or cargo container or latch or the like.
  • End pieces 12, 14 are formed via a forming process, such as by molding, such as injection molding or the like, and are joined together via at least one breakable or separable or frangible connecting element or portion 18 that is formed or molded during the forming process, as discussed below.
  • end pieces 12, 14 thus may be separated via breaking the frangible element 18 when it is desired to lock the locking device 10 to an object.
  • multiple end pieces 12, 14 and thus multiple locking devices 10 may be formed together and may be joined via breakable or separable or frangible portions or elements 20 such that a strip or series 22 of locking devices lOa-d (FIGS. 3-6 and 16) may be unitarily formed together, as also discussed below.
  • End piece 12 includes a generally cylindrical body portion 12a for receiving end 16a of rod 16 therein.
  • End piece 12 also includes a generally flat or planar surface 12b extending therealong and on which identification numbers or letters or characters or other indicia may be formed or printed or applied, in order to provide identification of each end piece 12.
  • generally flat surface 12b includes a roughened surface portion 12c, which may be roughened or uneven and may have a plurality of ridges and grooves formed therealong (as best shown in FIGS. 14 and 15), and a generally smooth surface portion 12d.
  • the roughened surface 12c provides a surface upon which the indicia may be printed, whereby the printed indicia will be difficult to alter or remove due to the uneven surface.
  • end 16a of rod 16 is inserted into a mold cavity and end piece 12 is molded therearound, such that rod 16 is fixedly secured to end piece 12 and extends therefrom, as discussed in detail below.
  • End piece 14 includes a generally cylindrical body portion 14a and a generally flat or planar surface 14b extending therealong and on which identification numbers or letters or characters or other indicia may be formed or printed or applied, in order to provide identification of each end piece 14.
  • generally flat surface 14b includes a roughened surface portion 14c, which may be roughened or uneven and may have a plurality of ridges and grooves 14d (FIG. 15) formed therealong, and a generally smooth surface portion 14e.
  • the roughened surface 14c provides a surface upon which the indicia may be printed, whereby the printed indicia will be difficult to alter or remove due to the uneven surface.
  • the identification indicia printed or formed on surface 14b of end piece 14 is preferably substantially identical to the identification indicia printed or formed on surface 12b of end piece 12, such that the end pieces are identifiable as being part of a single locking device.
  • Body portion 14a of end piece 14 is configured to receive end 16b of locking member 16 therein to lock the locking device 10 to an object (as shown in FIG. 2).
  • a locking element 24 (FIGS. 8 and 11) is inserted into a mold cavity and body portion 14a of end piece 14 is molded therearound, such that locking element 24 is fixedly secured at least partially within end piece 14.
  • Locking element 24 may comprise a cylindrical element 24a defining a passageway at least partially therethrough with a lock ring 24b positioned within cylindrical element 24a, such as within a channel 24c formed within cylindrical element 24a. Lock ring 24b engages end 16b of rod 16 when rod 16 is partially inserted into locking element 24 to secure end piece 14 to rod 16, as discussed below.
  • end piece 12 further includes a tab or loop 26 extending therefrom, while end piece 14 also includes a tab or loop 28 extending therefrom.
  • Tabs 26, 28 are configured to receive an identification strip or secondary seal 30 (FIG. 2), such as a thin metal strip with identification numbers or letters or characters or other indicia thereon, therethrough, such that the identification strip 30 may be attached to end pieces 12, 14. Accordingly, in order to unlock locking device 10, the identification strip 30 would have to be broken or damaged or cut, which would then provide a visible indication that the locking device has been tampered with.
  • an identification strip or secondary seal 30 FIG. 2
  • Locking member or rod 16 comprises a substantially rigid cylindrical rod formed of a metallic material (although the rod may be formed of other materials, without affecting the scope of the present invention).
  • End 16a of rod 16 may include a base or disc portion 32 (FIGS. 9 and 12), which may be inserted into the mold cavity of end piece 12 to secure rod 16 to end piece 12.
  • disc portion 32 may have a non-circular shape or may have one or more extensions extending radially outward from the base, in order to non-rotatably secure rod 16 within end piece 12 when molded therein.
  • the opposite end 16b of rod 16 includes a tapered or ramped or conical end portion 34 with a narrowed section 36 at the end of the tapered end portion 34.
  • the tapered end portion 34 is insertable into locking element 24 of end piece 14 and engages lock ring 24b. As the tapered end 34 is inserted further into locking element 24, lock ring 24b may slide along the ramped surface 34 and may expand to allow the tapered end portion to insert into locking element 24.
  • channel 24c is larger than the initial or normal size of lock ring 24b to allow for expansion of lock ring 24b as end 16b is inserted into locking element 24.
  • the lock ring 24b When the lock ring 24b reaches the narrowed section 36, the lock ring 24b contracts to its normal size and limits or substantially precludes retraction of rod 16 from locking element 24 via engagement with the ledge or lip or annular surface 35 (FIGS. 7 and 9) at the end of the tapered section 34. End 16b of rod 16 thus may be inserted into end piece 14 and retained therein when it is desired to lock the locking device to an object.
  • End pieces 12, 14 may be integrally formed or molded together in a mold cavity.
  • the mold cavity may include first and second cavity portions for forming the respective end pieces, and may also include one or more connecting cavity portions that interconnect the first and second cavity portions.
  • the connecting cavity portions may be narrowed at one or both end pieces, such that the frangible connecting elements are narrowed at one or more locations therealong (such as shown at the ends 18a of the frangible elements 18 in FIGS.
  • the end 16a and disc portion 32 of rod 16 may be inserted into the cavity portion for the first end piece 12, while the locking element 24 may be inserted into the cavity portion for the second end piece 14, such that the end pieces are molded around the rod and locking element during the molding process.
  • the entire locking device thus may be molded via a single molding process and may be retained together via the frangible elements, such that no other packaging or tie straps or the like are required to keep the end pieces together during shipping and handling of the locking device prior to actual use of the locking device.
  • a series or strip 22 of end pieces 12, 14 may be formed or molded via the single forming process.
  • the mold cavity thus may include a plurality of pairs of first and second cavity portions, and may connect the adjacent cavity portions of the adjacent pairs via one or more connecting channels or cavity portions. Accordingly, when the mold cavity is filled with the desired or suitable material (such as a durable and strong polymeric material), the end pieces are formed and are joined together via the material filling the respective connecting channels or cavity portions. The molded end pieces thus are joined to the adjacent end pieces via the frangible connecting elements formed during the molding process.
  • the desired or suitable material such as a durable and strong polymeric material
  • the identification numbers or characters or indicia may be applied to or printed on or formed on the surfaces of the corresponding end pieces of the strip without concern as to the matching end pieces being separated and mixed during shipping and handling of the locking devices and prior to their use at a particular object.
  • the first end piece 12 is joined to the respective second end piece 14 via a pair of frangible connecting elements 18, while the adjacent pairs of end pieces are connected together via a frangible portion 20 extending along and between the outer end portions of the tabs 26, 28 of the adjacent end pieces.
  • Each pair of respective end pieces 12, 14 (which may have the rod 16 and locking element 24 insert molded therein) are thus removably or separably joined together via frangible elements 18, while the adjacent locking devices lOa-d (each of which comprises a respective pair of end pieces 12, 14) are removably or separably joined together via frangible elements 20.
  • frangible elements or portions 20 may be tapered or narrowed (such as at the center region 20a shown in FIG. 10) to ease breaking of the frangible element 20 to separate the pairs of end pieces from the strip 22.
  • Multiple complete locking devices lOa-d thus may be provided in a single strip with no additional packaging or ties being required. Although shown as four locking devices formed or molded together, any number of locking devices may be formed or molded in the manner described herein, without affecting the scope of the present invention.
  • frangible connecting elements may be formed elsewhere between the end pieces (such as discussed below), without affecting the scope of the present invention.

  • the end pieces 12, 14 of the removed locking device may be readily separated by breaking the frangible element or elements 18 and the rod 16 may be inserted through the particular object to be locked or sealed.
  • the removed or separated end piece 14 may then be secured to the end 16b of the rod 16 to lock or seal the locking device to the object.
  • the metallic tamper indicating strip or identification strip or secondary seal 30 may be routed through the tabs or loops 26, 28 and secured so that the strip cannot be readily removed from the locking device without damaging or destroying the strip and/or the end pieces of the locking device.

  • an identification element provides or facilitates electronic tracking of the locking devices and provides a check to ensure that the locking device that was applied to a particular cargo container or item is still on the cargo container or item at a later date and, thus, provides a tracking and tamper resistant or tamper detection function.
  • an identification element such as a radio frequency identification (RFID) element or chip or tag 40 may be attached to or embedded in or molded into or otherwise incorporated into or onto one or both of the end pieces, such as the end piece 12, so that the locking device may be readily identified.
  • RFID radio frequency identification
  • Such an identification element may use radio waves to automatically identify the end piece and the locking device, such as by storing a unique serial number (or other identifying information) or the like that identifies the particular end piece and locking device.
  • the element or microchip may include or may be attached to an antenna that enables the chip to transmit the identification information to a reading device, which may convert the radio waves into digital information for automatically identifying the locking device via computers or the like, such that the locking devices may be automatically electronically tracked during use.
  • Such RFID chips or tags are known and may comprise a microchip with an antenna, and may be used in conjunction with an interrogator or reader with an antenna (which may be located at a shipping or receiving area or facility where the locked or sealed cargo items are shipped from or received at or the like).
  • the reader may send out electromagnetic waves and the RFID tag antenna may be tuned to receive these waves.
  • a passive RFID tag may draw power from the field created by the reader and may use the drawn power to power or enable or energize the microchip's circuits/
  • the chip may then modulate the waves that the tag sends back to the reader, and the reader may convert the new waves into digital data for processing.
  • the RFID chip may be preferred because a scanner does not need to be directed at the chip to "read" the chip, as is typically required with barcode scanners and the like.

Abstract

L'invention concerne un dispositif de verrouillage (10) comprenant une paire de pièces terminales (12, 14) et un élément de verrouillage (16). Une pièce terminale (12) reçoit une extrémité de l'élément de verrouillage, tandis que l'autre pièce terminale (14) est conçue pour recevoir l'autre extrémité lorsque l'élément de verrouillage est inséré dans un objet pour fixer par verrouillage l'objet le dispositif de verrouillage à l'objet. Les pièces terminales sont formées ensemble par un procédé de formage, et sont assemblés par au moins un élément ou une partie fragile (18, 20) qui est formé(e) ou moulé(e) pendant le procédé de moulage. Les pièces terminales peuvent ainsi être séparées par rupture de l'élément ou des éléments fragiles lorsque l'on souhaite verrouiller le dispositif de verrouillage à l'objet. De multiples dispositifs de verrouillage peuvent être formés ensemble et assemblés par des parties ou éléments fragiles de telle façon qu'une bande ou des séries (22) de dispositifs de verrouillage puissent être moulés en formant une seule pièce.
