Definitions

  • This invention relates to locking assemblies of the so-called staple and hasp type in which a staple is mounted to a first part to be locked, e.g. a door frame or door, and a hasp is mounted to the other part,.e.g. a door or the shaft of a bolt.
  • a staple is mounted to a first part to be locked, e.g. a door frame or door
  • a hasp is mounted to the other part,.e.g. a door or the shaft of a bolt.
  • the staple adapted to extend through an aperture in the hasp and the two may be locked together for example by means of a padlock.
  • Such locking assemblies are very well known and have a particular advantage over other locking arrangements in that an assembly may be readily mounted to for example a .door and frame not previously adapted to include a lock without the need for any modifications to either the door or the frame.
  • various methods and means are available to a prospective intruder to break the lock the most common of which involve hack-sawing through the staple and/or through the locking bar of the padlock or alterna- tively levering or forcing the staple from the wall by means of a ' chisel or the like.
  • GB-PS 1 602.013 discloses an arrangement which goes some way to increasing the security of such locking assemblies by providing a protecting member adapted to be engaged over the hasp and in use to shield from attack at least a part of a padlock lockingly engaged with the staple. Owing to its construction however this protecting member is still vulnerable to vertical or sideward blows because of the weakness of its engagement with the hasp and staple.
  • the invention provides a locking assembly comprising a hasp, a staple and a protecting member adapted to be engaged on the hasp and in use to shield from attack at least a part of a padlock lockingly engaged with the staple, the protecting member including a housing formed with a sideways facing opening adapted to receive . therethrough the hasp whereby frontal removal of the housing from the hasp is prevented, the housing having a further aperture through which in use and through the hasp aperture the staple protrudes to prevent lateral removal, the staple protruding into a chamber having a wall or walls which shield the padlock from said attack.
  • the housing which may be for example of steel plate and as such access for tampering with the heretofore vulnerable components of the assembly is considerably reduced.
  • the housing co-operates with the hasp so as to at least partially transmit lateral stresses imposed on the housing to the hasp mounting.
  • the opening in the housing is preferably adapted to snugly receive the hasp and the hasp is provided with an abutment adapted to limit movement of the hasp into the housing so as to correctly align the apertures.
  • the means in the housing adapted to abut the hasp comprises an apertured plate extending across the housing adjacent the housing opening; the plate is advantageously above the opening so that in use, in the locked position, the hasp lies adjacent and is concealed below and shielded by the plate.
  • the. housing includes a peripheral wall the lowermost portion of which is adapted to fit snugly over a mounting plate, of the staple which mounting plate is preferably partially embedded into the surface to which it is mounted. In this way any lateral stresses imparted to the housing in addition to being absorbed by the hasp mounting will be directly absorbed by the staple mounting plate. Thus, the staple itself is further protected from such lateral stresses. Furthermore, the staple may not be levered from, e.g.
  • the housing has a generally cylindrical peripheral wall in which the opening in the form of an elongate slot is formed.
  • the invention also extends to the provision of locking means mounted within the housing adapted for engagement with the staple.
  • the invention provides a locking assembly comprising a hasp, a staple and a locking and protecting member adapted to be engaged on the hasp and including.—, a housing formed with a sideways facing opening adapted to receive therethrough the hasp whereby frontal removal of the housing from the hasp is prevented, the housing having a further aperture through which in use and through the hasp aperture the staple protrudes to prevent lateral removal, the staple protruding into a chamber containing fixedly mounted locking means adapted to lockingly engage the staple in the closed condition.
  • the hasp is introduced into the housing via the opening and the housing is then urged against the staple so that the staple passes through both said apertures into the housing.
  • the locking means engages the staple and prevents removal of the housing and the hasp therefrom. The requirement of a separate padlock as the securing means -is therefore avoided.
  • the housing is closed at the front end thereof remote in use from the door or wall so that when locked the locking means, the staple and the end of the hasp are enclosed within and completely concealed by the housing.
  • the housing is closed at the front end thereof remote in use from the door or wall so that when locked the locking means, the staple and the end of the hasp are enclosed within and completely concealed by the housing.
  • the opening in the housing is preferably adapted to snugly receive the hasp whereby the housing co-operates with the hasp to transmit any lateral stresses imposed on the housing to the hasp mounting rather than directly to the staple.
  • the means adapted to abut the hasp comprises an apertured plate which extends across the housing adjacent the opening, which may conveniently be in the form of a slot formed in a peripheral wall of the housing, whereby in the locked position the hasp lies closely adjacent the plate.
  • the hasp may conveniently be provided with an abutment adapted for engagement with the peripheral wall which serves to limit movement of the hasp into the housing so as to correctly align the apertures.
  • a bottom portion of the housing peripheral wall is preferably adapted to fit over a mounting plate of the staple which plate is preferably partially embedded into the mounting surface.
  • the locking means may take any convenient form although in this embodiment it preferably comprises a pin and tumbler rotary lock having a rotatable locking cam adapted for engagement with the staple which, in this arrangement, is in the form of a hook-like member.
  • the housing is generally rectangular and has side walls adapted to abut in use the side edges of the hasp.
  • the means adapted to abut the hasp comprises an apertured plate extending at least partially across the interior of the housing and adapted in use to underlie the end of the hasp.
  • the hasp is preferably provided with an abutment adapted to engage the end of the apertured plate so as to correctly align the apertures. It will be seen that lateral stresses imposed on the housing will again be largely transmitted to the hasp mounting as a result of the side walls of the housing - bearing against the hasp. Again, part of the housing wall may be adapted to directly engage a mounting plate of the staple so that stresses are additionally transmitted to the mounting plate.
  • the locking means may convenient ⁇ ly comprise a mortise lock having a locking shaft engageable with the staple.
  • the lock body is preferably mounted against the front wall of the housing and overlies the housing opening.
  • a lock body securing plate preferably extends beneath the lock between two opposed shoulder portions of the housing side walls ⁇ -- and retains the lock body in position.
  • the securing plate may additionally be adapted to abut the top of the hasp and is spaced from the apertured plate so as to define a channel for snugly receiving in use, the end of the hasp.
  • a further strengthe ing plate may be provided overlying the lock body so as ⁇ to protect the lock mechanism from possible attack by drilling through the front of the housing.
  • the assembly when locked is of smart appearance since the lock mechanism and the staple are completely concealed by the housing.
  • the hasp may be secured to the shaft of a locking bolt and be adapted for engagement with the staple when the bolt is in its locked condition.
  • Figure 1 is a perspective view of a first embodiment of the invention showing the various components in the unlocked position.
  • Figure 2 is a cross-sectional view of the locking assembly shown. in Figure 1 in the locked position.
  • Figure 3 is a view similar to Figure 2 but showing a second embodiment of the invention.
  • Figure 4 is a view similar to Figure 3 only showing a third embodiment.
  • Figure 5 is a perspective view from underneath on a slightly enlarged scale of the housing for the embodiment of the invention illustrated in Figure 4.
  • Figure 6 is a perspective view of a further embodiment.
  • a locking assembly including a hasp 1, a staple 2 and a housing 3 having a generally cylindrical peripheral wall 4.
  • a plate 5 having a slot-like aperture 6 is provided within the housing 3 and overlies a slot 7 formed in the lower portion of the peripheral wall 4.
  • the hasp 1 includes a mounting portion 8 adapted to be secured to for example a door by means of screws, which is hingedly attached to a portion 9 having an aperture 10.
  • An arcuate abutment surface 11 having a similar radius of curvature to the outer surface of the housing peripheral wall 4 is formed on the -underside of the portion 9 of the hasp.
  • the staple 2 includes an aperture 12 adapted to receive a conventional padlock or the like (not shown) and is securable to for example a wall by means of a circular mounting ' plate 13 which is of similar radius to the inside surface of the housing peripheral wall 4.
  • the hasp 1 and the staple 2 are respectively mounted ' to two relatively movable parts to be locked, for example a door and a door frame.
  • the mounting plate 13 of the staple 2 is partially embedded into the surface to which it is mounted.
  • the apertured portion 9 of the hasp 1 is introduced into the housing via the slot 7.
  • the housing 3 is slid on to the portion 9 until the abutment surface 11 of the hasp engages the outer surface of the lower portion of the peripheral wall 4 whereupon the aperture 10 in the hasp is aligned with the aperture 6 in the plate 5.
  • the padlock, the staple and the end of the hasp are all at least partially shielded from attack by the housing and it is not ' possible for a prospective intruder to, for example, hacksaw through the arm of the padlock or through •the staple.
  • the interaction between the housing .and the hasp is such that any lateral forces imposed on the housing will be at least partially transmitted to the hasp rather than to the staple.
  • the staple is further protected from such forces by the fact that the bottom of the peripheral wall 4 fits over and abuts the staple base portion 13 and as such lateral forces will be partially absorbed directly by the base portion 13 rather than the staple itself.
  • the base portion 13 being partially embedded in the mounting surface, cannot be .prised from the wall by sliding a chisel or the like beneath the peripheral wall 4 of the housing since the chisel would simply abut the step 14 formed by the base portion 13 adjacent the peripheral wall 4 and therefore could not be slid underneath the base portion 13.
  • Figure 3 a second embodiment of the invention is illustrated.
  • the cylindrical housing is closed at its front end by means of a front wall 15 which mounts a conventional rotary cylinder lock-16 which is secured in an opening in the front wall 15 by means of a lock nut 17.
  • the hasp 1 and the staple 2 in this embodiment are the same as those illustrated in Figure 1 although the staple is cut away at one side, as shown in dotted lines in Figure 1, so as to be generally C-shaped.
  • the locking procedure in this embodiment is the same as for the Figure 1 embodiment except that 5 instead of engaging the staple with a padlock, when in the closed position a key is inserted into the cylinder lock 16 and rotated so that a locking cam thereof engages the staple aperture 12 via the cutaway portion of the staple. It will be seen that in this 10 embodiment the aforesaid advantages concerning security are equally fulfilled and furthermore the locked assembly has a particularly smart external appearance since all the locking components are concealed within the housing.
  • a third embodiment of the invention is illustrated in Figures 4 and 5 and in this embodiment the housing 19 is generally rectangular in shape.
  • the housing 19 is provided with a plate 20 having an aperture 25 21 adapted to be aligned in use with a corresponding aperture formed in the hasp 22.
  • the hasp 22 is introduced into the housing via an opening 23 adjacent the plate 20.
  • the plate 20 underlies the apertured' portion of the hasp, " 30 unlike the embodiments shown in Figures 1 and 3, and an abutment surface 24 formed on the underside of the hasp abuts the end of the plate 20.
  • the side walls 25, 26 of the housing abut the edges of the hasp 22 so as to ensure a snug fit between 35 the hasp and the housing.
  • the locking means in this embodiment comprises a mortise lock 27 having a shaft 28 adapted for engagement_ with the staple.
  • the lock 27 is held in position by means of a plate 29 extending between two shouldered portions 30 secured to the side walls. As seen in Figure 4, the plate 29 abuts the top surface of the hasp 22 in the locked position and furthermore defines a channel between the plate 29 and the plate 20 adapted to snugly receive the end of the hasp 22.
  • the plate 29 is secured to the shouldered portions 30 by means of screws or rivets 31 and to prevent the heads of the screws or rivets 31 fouling with the top surface of the hasp 22 in the locked position, recesses 32 * are provided in, the shouldered portions.
  • a locking bolt 32 extends through and is slidably mounted in a cast-iron casting 33 which is mounted to for example a door by means of screws or bolts (not shown) .
  • the free end 34 of the bolt 33 is adapted to engage in a suitable socket (not shown) secured to or embedded in the door frame so as to prevent opening.
  • a hasp which comprises a first portion 35 with a second, apertured portion 36 welded thereto.
  • the locking assembly also includes a staple (not shown) which is positioned on the door adjacent the bolt whereby with the bolt in its locked position the hasp may be closed over the staple which extends through the hasp aperture 37.
  • the final component of the assembly is a housing 38 provided with an opening 39 adapted to receive the end of the hasp prior to closing the hasp over the staple.
  • the housing is similar to that described in Figures 4 and 5.
  • the interior of the housing is provided with a laterally extending plate having an aperture adapted in use to align with the hasp aperture, the staple extending through both apertures on closing.
  • the step 40 formed at the end of the first hasp portion 35 engages the end of the plate in the aligned position.
  • a mortise lock or similar locking means is mounted within the housing and includes a shaft adapted for engagement with the staple in the closed position so as to prevent unlocking. Access to the mortise lock is provided via- a key hole 41.
  • the lock means is at least partially shielded from attack by the housing. Furthermore, lateral forces imposed on the housing, for example by striking it with a hammer, are transmitted partially to the hasp mounting 8 by the interaction between the housing and the hasp, and to the mounting plate of the staple owing -to direct engagement between the bottom of the housing and the mounting plate. Thus, such lateral stresses do not bear ' on the staple itself or on the lock means, whether it is a padlock as in the case of the Figure 1 embodiment or a rotary or mortise lock as shown in Figure 3, Figure 4 and Figure 6 embodiments.
