Definitions

  • This invention relates to a padlock for securement of possession, more specifically, to a padlock having tamper evident feature.
  • the padlock is a convenient lock used to secure possession from unauthorised manipulation or theft.
  • a padlock is provided with a tamper evident feature to provide evidence that a iocked possession has been tampered with.
  • Most tamper-evident padlocks as used on airline trolleys or luggage consist of a lock body, a hasp, and a locking key (also known as a disposable seal). This type of padlock frees the user of need to carry a key, an advantage which eliminates possibility of loss of the key. Compared to padlock with number combination codes, the user needs not memorise the code or worry about jammed dials.
  • US 71 18144 B2 discloses a tamper-evident padlock and padlock combination.
  • the padlock has a moulded plastic lock body which includes an open-ended passage and an opening spaced from the passage, There is also a hasp which has first and second spaced apart legs. An end of the first leg can be located in the passage through a first end thereof whiie the end of the second leg can be located simultaneously in the opening. The end of the first leg in the passage can then be engaged by a breakable seal which is inserted into the passage through the opposite end of the passage, in order to lock the hasp relative to the lock body.
  • the padlock combination comprises the padlock and the seal in combination.
  • a drawback of the above-mentioned invention is that any pul!lng force exerted on the hasp transfers directly to the frangible portion of the seal, which at times causes accidental breakage of the seal, resulting in removal of the hasp from its Iocked position.
  • US 7370892 B2 discloses a security seal which has housing and a hasp moveable relative to the housing in a first direction between a Iocked position and an unlocked position.
  • the hasp in the locked position, is !ockable to the housing by a disposable seai.
  • the housing has an opening to ailow the insertion of the disposable seal in a second direction different from the first direction.
  • the hasp includes a first locking element engageable, in the locked position, with a second, matching Socking element of the disposable sea! to prevent movement of the hasp in the first direction toward the unlocked position and withdrawal of the disposable seal in the second direction.
  • the hasp is attached to the housing so as to be both slidable and pivotabfe relative to the housing.
  • a padlock which comprises a generally U-shaped hasp, a lock body, and a locking key.
  • the hasp has one leg longer than the other.
  • Said longer leg has an end portion wider than the rest of the hasp.
  • the wider portion has an elongate slot which extends parallel to the leg, and a recess which opens sideways towards the shorter leg.
  • the lock body the interior of which has a first blind passage towards one side of the body for receiving the wider portion of the hasp and has a peg for engagement with the slot in the wider portion, a second blind passage for receiving the shorter leg, a third passage for receiving a locking key which has a chamfered end, and a transverse passage for receiving a spring loaded locking pin.
  • the arrangement is such that the hasp can be moved between a locked position in which the locking pin is engaged in the recess in the wider portion, and an unlocked position in which the locking pin extends into the third passage under the Influence of the spring .
  • the locking key comprises a shaft which has an undercut chamfered end that when inserted into the third passage engages the chamfered end of the locking pin, and forces it into the transverse passage to enter the recess in the wider portion, after which the locking pin springs back to engage under the undercut to prevent removal of the key, Said key has a frangible end portion of the shaft to ho!d the key in position until the end portion is broken off.
  • the longer leg has a protrusion disposed on the side opposite the edge of the wider portion; said protrusion hinders intrusion to the interior of the lock body when the hasp is in the locked position,
  • the first passage is defined by a generally P-shaped depression which has the head portion of the P shape trimmed to a!lovv the hasp to rotate about the peg.
  • the invention also discloses a method for locking the padlock.
  • the method comprises a step of inserting the shaft of the locking key into the third passage via an opening of the third passage disposed on an end of the lock body opposite the hasp, such that the chamfered end of the shaft engages the chamfered end of the locking pin, and forces it into the transverse passage to enter the recess in the wider portion , after which the locking pin springs back to engage under the undercut to prevent removal of the key.
  • the invention discloses a method for unlocking the padlock.
  • the method comprises steps of: tearing along the frangible end portion of the shaft of the locking key, and breaking off the tab portion and the transverse portion of the key; and pushing the shaft and the undercut head through the passage to release the locking pin.
  • FIG. 1 is a perspective view of one form of a padlock according to the invention, in which a hasp is in a locked position and a locking key is disengaged from a through passage of a lock body;
  • Fig. 2 is a partially exploded view of the padlock shown in Fig. 1 ;
  • FIG. 3 is a front view of the padlock shown in Fig. 1 with a lock cover removed and the hasp in a locked position;
  • Fig. 4 is a front view of the padlock shown in Fig. 1 with the lock cover removed, the hasp In the locked position, and a shaft of the locking key residing in the through passage in the lock body.
  • a padlock comprises a lock body that is formed by two parts 1 a, 1 b.
  • the lock body 1 has a first blind passage 9 disposed in proximity to one edge, a second b ⁇ m ' 0 passage 1 1 parallel to the passage 9, at about the middle of the Sock body 1 , a through passage 12 disposed in proximity to an opposing edge of the lock body 1 , and a

  • the longer leg 3 has a protrusion 24 disposed on the side opposite the edge of the wider portion 4 to prevent access to the interior of the lock body 1 when the hasp 2 is in the locked position.
  • the first passage 9 receives the wider portion 4 of the hasp 2 and has a peg 10 for engagement with the slot 6 In the wider 5 portion 4; the first passage 9 is defined by a generally P-shaped depression having the head portion of the P shape trimmed to allow the hasp 2 to rotate about the peg 10.

Abstract

L'invention concerne un cadenas qui comprend un moraillon présentant généralement la forme d'un U (2), un corps de serrure (1) et une clé de verrouillage (13). Le moraillon (2) présente une branche plus longue que l'autre. Ladite branche plus longue (3) est dotée d'une partie d'extrémité (4) plus large que le reste du moraillon (2). La partie plus large (4) présente une fente allongée (6) qui s'étend parallèlement à la branche (3) et un évidement (7) qui s'ouvre latéralement en direction de la branche plus courte (5). L'intérieur du corps de serrure (1) présente un premier passage aveugle (9) en direction d'un côté du corps (1) destiné à recevoir la partie plus large (4) du moraillon (2) et présente une cheville (10) destinée à venir en prise avec la fente (8) dans la partie plus large (4), un deuxième passage aveugle (11) destiné à recevoir la branche plus courte (5), un troisième passage (12) destiné à recevoir une clé de verrouillage (13) qui présente une extrémité chanfreinée (14), et un passage transversal (15) destiné à recevoir une goupille de verrouillage à ressort (17). L'agencement est tel que le moraillon (2) peut être déplacé entre une position verrouillée dans laquelle la goupille de verrouillage (17) est en prise dans l'évidement (7) dans la partie plus large (4) et une position déverrouillée dans laquelle la goupille de verrouillage (17) s'étend dans le troisième passage (12) sous l'influence du ressort (18). L'invention concerne également des procédés de verrouillage et de déverrouillage du cadenas.
