Abstract

Abstract Lock-protecting hasp which secures to at least one door and a member or to two doors and a subsequent shackle lock whether the lock be key or combination and protects the shackle from being cut or pried off the body of the lock or between the shackle, the body and the lock-protecting hasp. The lock-protecting hasp includes two outside mount hasps, a spacer secured to each of the outside mount hasps, and a protector block engaged to each of the outside mount hasps. The lock-protecting hasp particularly lends itself to use on semi-trailers. The lock-protecting hasp accepts any lock of suitable size.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 181 words
A lock-protecting hasp for use on a stationary member and a movable member, the lock-protecting hasp comprising: opposing aligned outside mounting hasps, each of said mounting hasps including a longitudinal member having a plurality of bolt holes, an angular member connected to the longitudinal member rising upward at a slight angle from said longitudinal member, and a vertical leg connected to said angular member, two elongated holes in said leg for accepting a shackle of a lock, a spacer member on each of said legs of said outside mounting hasp and including two aligned elongated holes for accepting said shackle of said lock, and a protector block affixed to a top of said spacer and running substantially the distance above said elongated holes whereby said shackle connects through each of said aligned holes of said aligned outside mounting hasps and said spacer thereby substantially protecting small space exposed between said shackle and said lock body of said legs of said outside mounting hasps and thereby securing said space between said shackle, said lock body, and said spacer by said protector block.
Claim 2
Dependent Claim 181 words
A lock-protecting hasp for use on a stationary member and a movable member, the lock-protecting hasp comprising: opposing aligned outside mounting hasps, each of said mounting hasps including a longitudinal member having a plurality of bolt holes, an angular member connected to the longitudinal member rising upward at a slight angle from said longitudinal member, and a vertical leg connected to said angular member, two elongated holes in said leg for accepting a shackle of a lock, a spacer member on each of said legs of said outside mounting hasp and including two aligned elongated holes for accepting said shackle of said lock, and a protector block affixed to a top of said spacer and running substantially the distance above said elongated holes whereby said shackle connects through each of said aligned holes of said aligned outside mounting hasps and said spacer thereby substantially protecting small space exposed between said shackle and said lock body of said legs of said outside mounting hasps and thereby securing said space between said shackle, said lock body, and said spacer by said protector block.
Claim 3
Dependent Claim 28 words
The lock-protecting hasp of claim 1 wherein said elongated holes of said spacer are larger than said elongated holes in said leg providing for positioning of said shackle.
Claim 4
Dependent Claim 32 words
The lock-protecting hasp of claim 1 wherein said elongated holes in said leg include an outer radial circumference on each of said holes providing for rotation of said shackle within said leg.
Claim 5
Dependent Claim 36 words
The lock-protecting hasp of claim 1 wherein said elongated holes in said spacer include an outer radial circumferential circular edge at each of the outer ends of said elongated holes providing for rotation of said shackle.
Claim 6
Dependent Claim 19 words
The lock-protecting hasp of claim 1 wherein said elongated holes are larger in said spacer than in said leg.
Claim 7
Dependent Claim 24 words
The lock-protecting hasp of claim 5 wherein said elongated holes in outer circular circumferential edges are larger in said spacer than in said leg.
Claim 8
Dependent Claim 36 words
The lock-protecting hasp of claim 1 comprising an inside mounting support plate for each of said outside mounting hasps including a plurality of bolt holes in alignment with said bolt holes in said outside mounting hasps.
Claim 9
Dependent Claim 15 words
The lock-protecting hasp of claim 7 wherein said bolts are round-headed square shank carriage bolts.
Claim 10
Dependent Claim 74 words
The lock-protecting hasp of claim 7 comprising an inside mounting support plate for each of said outside mounting hasps including a plurality of aligned bolt holes and upward rising lips on each end of said plate and a corresponding panel including corresponding lips for sliding frictional engagement with said inside mounting support plate whereby said corresponding channel slidably and frictionally engages with said lipped inside mounting support plate and covers said nuts and bolts.
Claim 11
Dependent Claim 40 words
The lock-protecting hasp of claim 9 wherein said outside channel includes at least one closed end and another scored end whereby said scored end is hammered into position when said outside channel is engaged to said inside mounting support plate.
Claim 12
Dependent Claim 218 words
A lock-protecting hasp for trailer doors of a semi-trailer comprising opposing and geometrically identical outside mounting hasps including a longitudinal rectangular member having a plurality of bolt holes, an angular member rising from said longitudinal rectangular member at a slight angle, and a vertical leg connected to said angular member, said vertical leg including two elongated axially aligned holes for accepting the shackle of a lock and including outer circumferential enlarged ends, a spacer secured to said leg having substantially the same size as same leg and including two elongated aligned holes of a slightly larger size than said holes in said leg and including outer radial circumferential edges slightly larger than the corresponding holes in said spacer, a rectangular bar protector block secured to said spacer above said holes and an inside mounting support plate having a longitudinal rectangular size whereby said longitudinal member mounts to said door on the outer side and said inside mount support plate mounts on the inner side with round-headed square-shank carriage bolts securing said members to said doors, and a shackle lock fits into said opposing holes and through the other set of said opposing holes and is locked thereto, thereby securing said hasp members together and said protector block isolates said shackle of said lock body from outside removal means.
Claim 13
Dependent Claim 218 words
A lock-protecting hasp for trailer doors of a semi-trailer comprising opposing and geometrically identical outside mounting hasps including a longitudinal rectangular member having a plurality of bolt holes, an angular member rising from said longitudinal rectangular member at a slight angle, and a vertical leg connected to said angular member, said vertical leg including two elongated axially aligned holes for accepting the shackle of a lock and including outer circumferential enlarged ends, a spacer secured to said leg having substantially the same size as same leg and including two elongated aligned holes of a slightly larger size than said holes in said leg and including outer radial circumferential edges slightly larger than the corresponding holes in said spacer, a rectangular bar protector block secured to said spacer above said holes and an inside mounting support plate having a longitudinal rectangular size whereby said longitudinal member mounts to said door on the outer side and said inside mount support plate mounts on the inner side with round-headed square-shank carriage bolts securing said members to said doors, and a shackle lock fits into said opposing holes and through the other set of said opposing holes and is locked thereto, thereby securing said hasp members together and said protector block isolates said shackle of said lock body from outside removal means.
Claim 14
Dependent Claim 14 words
The lock-protecting hasp of claim 11 wherein said outside mounting hasp is 3/16" steel.
Claim 15
Dependent Claim 12 words
The lock-protecting hasp of claim 11 wherein said spacer is 1/8" steel.
Claim 16
Dependent Claim 15 words
The lock-protecting hasp of claim 11 wherein said inside mount support plate is 1/8" steel.
