Abstract
A shielded lock assembly for a padlock for securing a pair of closure members and comprising a staple secured to one closure member and a hasp secured to the other closure member. The hasp has a back plate for securing the hasp to the closure member and a front plate hingedly connected to the back plate for movement to a closed position in which the front plate overlies the staple, the front plate having a slot for receiving the loop portion of the staple and a tubular shield which circumscribes the slot and extends outwardly from the front plate at an angle to an open end which allows the insertion of a human hand into the shield for application of a padlock to the staple to secure the hasp in the closed position and to permit subsequent unlocking of the padlock.
Claims11
Lock assembly for securing first and second closure members, comprising:
- (a) a staple secured to one of said closure members and having a padlock receiving loop,
- (b) a hasp having a back plate secured to the other of said closure members, and a front plate hingedly connected to the back plate for movement from an open position in which the front plate is clear of said one closure member to a closed position in which the front plate overlies said loop, said front plate having a slot for receiving the loop of said staple so that loop extends forwardly of the outwardly facing surface of the front plate when the front plate is in said closed position,
- (c) a padlock having a body portion, a shackle at one end of the body portion, and a keyhole at the other end of the body portion, said shackle being adapted to extend through the loop portion of said staple to secure the front plate of said hasp in said closed position, and
- (d) a tubular shield having an inner end which is fixed to said outwardly facing surface and which completely circumscribes said slot, said shield having an outer end which has an opening that is large enough to permit the insertion of a human hand, said tubular shield defining a cavity having a central longitudinal axis which extends at a substantial angle to the plane of said outwardly facing surface, said tubular shield being sufficiently long so that an adult human hand must be inserted beyond the wrist joint in order to reach the padlock.

Hasp for a padlock assembly, comprising:
- (a) a back plate which is adapted to be secured to a flat surface,
- (b) a front plate which is hingedly connected to the back plate and having a slot for receiving the loop portion of a padlock staple, and
- (c) a tubular shield having an inner end which is fixed to one broad side of the front plate and which completely circumscribes said slot, said shield having an outer end which has an opening that is large enough to permit the insertion of a human hand, said tubular shield defining a cavity having a central longitudinal axis which extends at a substantial angle to the plane of said outwardly facing surface, said tubular shield being sufficiently long so that an adult human hand must be inserted beyond the wrist point to reach a padlock which is attached to the padlock staple.
Lock assembly for securing first and second closure members, comprising:
- (a) a face plate secured to one of said closure members, and having an outwardly facing flat surface,
- (b) a padlock receiving loop extending from the outer flat surface of said face plate,
- (c) a hasp having a back plate secured to the other of said closure members, and a front plate hingedly connected to the back plate for movement from an open position in which the front plate is clear of said one closure member to a closed position in which the front plate overlies said loop, said front plate having a slot for receiving the loop of said staple so that loop extends forwardly of the outwardly facing surface of the front plate when the front plate is in said closed position, said front plate having a lip which extends rearwardly about the periphery of the inwardly facing surface of said front plate so as to define an inwardly facing recess so that when said inwardly facing surface abuts said face plate, the face plate is enclosed within sait recess,
- (d) a padlock having a body portion, a shackle at one end of the body portion, and a keyhole at the other end of the body portion, said shackle being adapted to extend through the loop portion of said staple to secure the front plate of said hasp in said closed position, and
- (e) a tubular shield having an inner end which is fixed to said outwardly facing surface and which completely circumscribes said slot, said shield having an outer end which has an opening that is large enough to permit the insertion of a human hand, said tubular shield defining a cavity having a central longitudinal axis which extends at a substantial angle to the plane of the outwardly facing surface of said front plate.
