Description of embodiments

Figure 1 shows a front view of an embodiment of a hasp generally indicated by the numeral 10. Figure 2 and 6 show perspective and top views corresponding to figure 1. The hasp 10 is mounted to a movable barrier 12 in the form of a swinging door. Other examples of movable barriers to which the hasp 10 may be attached include but are not limited to a sliding door and a closure for a chest. Generally, the hasp 10 may be attached to any suitable movable barrier. In figures 1 and 2, the hasp 10 secures the movable barrier 12 to a structure 14 in the form of a door frame adjacent the movable barrier 12, without the use of a padlock. Figures 3 and 4 show a front view and a perspective view respectively of the hasp 10, in which the hasp 10 does not secure the movable barrier 12 to the structure 14. The hasp 10 comprises a hasp body 16. The hasp 10 comprises an attachment plate 18 to which to hasp body 16 is attached. The hasp 10 is configured for receiving within an end 39 thereof a longitudinally orientated lock cylinder 22, the lock cylinder 22 being in the form of a key-in-knob lock cylinder, a rear view of which is shown by figure 10. In the context of this document, longitudinallyorientatedmeans that the lock cylinder runs substantially lengthwise with respect to the hasp 10. The hasp 10 comprises a bolt 20 movably mounted within the hasp body 16. The lock cylinder 22 when so received is operationally coupled to the bolt 20 for actuation thereof.

The hasp body 16 has an end 40 at which the attachment plate 18 is attached, and another end 38 at which with cylinder lock is disposed. The hasp body 18 is elongated between the end 15 and the other end 17, defining the lengthwise direction.

Revealed in figures 3 and 4 are a portion of the attachment plate 18 and a staple 24 attached to the structure 14. The bolt 20 can be actuated by the lock cylinder 22 into and out of receipt by the staple 24. The staple 24 comprises a keeper 26 opposite the attachment plate 18 and defining an aperture 28 in which the bolt 20 is receivable for engagement of the hasp 10 with the staple

24. The movable barrier 12 is secured when the hasp 10 is engaged with the staple 24. In the present but not all embodiments, the hasp 10 comprises a plurality of bolts 20, 241 - specifically but not limited to 2 bolts - that are operationally coupled to the lock cylinder 22. The bolts 20,241 are actuatable by the lock cylinder 22. The staple 24 comprises another keeper 30 for the other of the plurality of bolts 20,241.

Figure 5 shows the hasp 10 and superimposed thereon a lateral section line A-A and a longitudinal section line B-B. Figure 7 shows a sectional view of the hasp 10 through section line B-B of figure 5, revealing that the hasp body 16 comprises a hasp body shell 36 in which is received the longitudinally orientated lock cylinder 22. The lock cylinder 22, while longitudinally orientated, is inclined with respect to the attachment surface 42 of the movable barrier 12 when the hasp 10 is engaged to the staple, and also inclined with respect to the rear face 23 of the hasp body 16. The lock cylinder face plate 32 and keyhole 34 of the lock cylinder 22 are at an end 38 of the hasp body 16 in which the cylinder lock is received. The outer surface 44 of the face plate 32 and keyhole 34 surround 46 are inclined at an acute angle with respect to the attachment surface 42 of the movable barrier 12 and the rear face 23 of the hasp body, which generally increases their exposure. A key when received by the lock cylinder 22 is inclined with respect to attachment surface 42. The inclination may reduce the effort required to locate the keyhole 34, reduce the effort required to insert the key into the lock cylinder 22, reduce the effort required to remove the key from the lock cylinder 22, and/or provide more clearance around the keyhole 34 for fingers. The attachment plate 18 is attached to another end 40 of the hasp body 16. The keyhole 34 of the cylinder lock 22 when so received is at an end-face of the hasp body 16, and is orientated away from the attachment plate 18.

Figure 9 shows a partially exploded view of a lock mechanism module 48 of the hasp 10 that is received within a cavity of the hasp body shell 36. The rear face 23 of the hasp body shell 36 defines an opening into the cavity through which the lock mechanism can pass during insertion into the cavity and removal from the cavity. The module 48 is configured to internally mount the lock cylinder 22 within a module cavity 50 defined by module shell 54. The module shell 54 is fastened to the hasp body shell 36 by a plurality of fasteners in the form of screws 53 that pass through apertures 55 formed in the module shell 54 and are held by tapped holes formed in the hasp body shell 36 or by nuts held thereat for example, although any suitable fastener - for example a rivet - may be used. The module 54 has a module closure 52 in the form of a cap plate 52 configured to be fastened to the module shell 54. The module closure 52 has a plurality of apertures 57 for passage of a plurality of fasteners 59 in the form of screws and the module shell 54 has tapped holes for holding the screws. It will be appreciated that generally any suitable form of fastener - for example rivets - may be used. Removable fasteners - for example screws and clips - may enable easier removal of the lock module 48 for re-keying or replacement of the lock cylinder 22. The lock module 48 is fastened to the hasp body 16, and so it may be difficult to misplace or attack the lock cylinder 22.

Figures 10 and 11 show alternative perspective views of parts of a locking mechanism mounted in the module shell 54. The locking mechanism comprises the lock cylinder 22 and a cam 58 rotationally coupled to the lock cylinder 22. The cam 58 is adjacent an end of the lock cylinder 22 comprising a lock cylinder actuator 60 in the form of a flat bar that is rotationally actuated by rotation of the key in the lock cylinder 22. The cam 58 defines a slot 62 in which the flat bar 60 is disposed for coupling the cam 58 and the flat bar 62. The cam 58 is in the form of a cam plate comprising a face 64 orientated away from the cylinder lock 22 and to which is attached a first follower driver 68 and a second follower driver 70, each in the form of a key comprising a circular boss. The bolts 20 and 241 each comprise a cam follower 72,74 in the form of a laterally orientated bar. The cam followers 72,74 define a key receiving socket 76,78 defined by an arcuate bearing surface 80. The follower drivers 68,70 are each received by one of the receiving sockets 76,78 to engage the arcuate bearing surfaces 80. The cam followers 72, 74 engage the cam 58 to convert a key rotation within the lock cylinder 22 to a lateral movement of the movable bolts 20,241. The follower drivers 68,70 are antipodal, and so the movable bolts 20, 241 are moved in counter lateral directions. The movable bolts 20,241 are slidingly mounted within the module shell 54 and on laterally orientated plain linear bearings for linear translation. The bearings may alternatively be ball or roller bearings, or the movable bolts may be mounted on gears, for example.

Figure 17 shows a top view of the lock mechanism module of figure 9 with the locking bolts extended and showing section line C-C. Figure 19 shows a sectioned view of FIG. 17 through section line C-C. Figure 18 shows a top view of the lock mechanism module with the locking bolts retracted and showing section line D-D. Figure 20 shows a sectioned view of FIG. 18 through section line D-D.

The hasp 10 comprises ajoint 82 joining the attachment plate 18 and the hasp body 16. The joint 82 is configured to have two rotational degrees of freedom so that when the hasp 10 is attached to the attachment surface 42 the hasp body 16 may be swung perpendicular to the attachment surface 42 and away from the staple, and also swung parallel to the attachment surface 42 and away from the staple. The joint has a translational degree of freedom for translating the hasp body toward and away from the staple, allowing errors in the placement of staple 24 or changes in the distance between the attachment plate 18 and the staple 24 due to, for example, expansion or contraction of the movable barrier 12 or structure 14. The joint 82 comprises a hinge 84 comprising the hasp body 16 attached to a hinge leaf 84 by a pin 86. The pin is disposed in a pair of low friction bearings in the form of teflon or nylon washers 88 between which is received the hinge leaf 84, which may reduce friction between the hasp 16 and the hinge leaf 84. A T-slot 88 is formed at an attachment surface of the hinge leaf 84 in which is slidingly captured an undercut boss 90 for translating the hasp body towards and away from the staple 24. The undercut boss 90 is attached to the attachment plate 18 and may be integral thereto. The T-slot 88 and the undercut boss 90 are configured for at least ninety degrees of rotation of the undercut boss 90 within the T-slot 88, in this embodiment by the circular boss 90 having a diameter less than the transverse width of the slot. The T-slot is closed with a closure 89 secured with fasteners in the form of press fitted pins 91, however screws or generally any suitable fastener or adhesive may be used. When closed, the undercut boss 90 cannot be removed from T-Slot 88. In an alternative embodiment, the rotational angle may be less and/or the T-slot may not be closed so the hasp body 16 can be separated from the attachment plate 88.

As shown in figure 30, the hasp 10 comprises a plurality of inwardly movable ventral bosses 92,93 that are outwardly biased by resilient members 94,96 in the form of compression springs, or alternatively an elastomer, for example. The inwardly movable ventral bosses may prevent rattling of the hasp body 16 against the attachment surface 42, for example. The compression springs 94,96 are held within their receiving apertures by a friction fit between an end of the spring, which is oversized. The bosses 92,94 are attached to the springs 94,96 by a resistance fit, adhesive, fastener or generally any suitable means.

As shown in figure 30, the hasp 10 comprises a plurality of attachment bolts 98,100 that pass through the attachment plate 18, through the movable barrier 12 and engaged with a threaded bolt plate 102. The staple 24 is similarly attached to the adjacent structure 14. The attachment plate 18 is ventrally disposed to the hasp body 16 when the hasp 10 is engaged to the staple 24, and so is protected from attack by the hasp body 16. The staple 24 is also ventrally disposed to the hasp body 16, when the hasp 10 is engaged to the staple 24, also protecting the staple 24 and staple attachment fasteners 104, 106 from attack. In another embodiment, the bolts 98, 100, 104 and 106 are replaced with surface mount fasteners, particularly if it is not possible or suitable to have through mounted fasteners. For example the staple 24 may be through mounted onto a door, but because of the thickness of the door frame the hinge is required to be surface mounted.
