Abstract

Abstract Lock-protecting hasp for trailer full swing rear doors having locking bars which secures to the bars of the rear doors and includes two mating members and a shackle lock whether the lock be key or combination. A protecting block against the lock on the female mating member protects the shackle of the lock from being cut or pried off the body of the lock, or between the shackle, the body and the lock-protecting hasp. Longitudinal opposing slots and a ribbed locking bar on the male mating member provide for adjustability between the two members for accepting door bars spaced any distance dependent upon the type of trailer. The lock-protecting hasp particularly lends itself to use on semi-trailers having full swing rear doors and the lock-protecting hasp accepts a lock of predetermined size.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 167 words
Lock-protecting hasp for use with opposing bars of full swing rear truck trailer doors, said lock-protecting hasp comprising: opposing aligned male and female mating J-shaped members, each of said mating members including opposing holes, said female member including opposing channels on an inside leg of said J member for accepting said male member and a protector block on an outside leg of said J member, adjacent said opposing holes, said male member including opposing longitudinal slots in a leg of said male member and a longitudinal ribbed locking bar on an inside of said leg between said longitudinal slots whereby a shackle of a lock connects through each of said aligned holes of said mated members and said shackle engages between two of said ribs when said members are adjusted together about bars of said trailer doors and said protector block is adjacent said lock, thereby preventing any area or space exposed between said shackle and said lock body of said legs of said outside mounting hasps.
Claim 2
Dependent Claim 167 words
Lock-protecting hasp for use with opposing bars of full swing rear truck trailer doors, said lock-protecting hasp comprising: opposing aligned male and female mating J-shaped members, each of said mating members including opposing holes, said female member including opposing channels on an inside leg of said J member for accepting said male member and a protector block on an outside leg of said J member, adjacent said opposing holes, said male member including opposing longitudinal slots in a leg of said male member and a longitudinal ribbed locking bar on an inside of said leg between said longitudinal slots whereby a shackle of a lock connects through each of said aligned holes of said mated members and said shackle engages between two of said ribs when said members are adjusted together about bars of said trailer doors and said protector block is adjacent said lock, thereby preventing any area or space exposed between said shackle and said lock body of said legs of said outside mounting hasps.
Claim 3
Dependent Claim 25 words
The lock-protecting hasp of claim 1 wherein said opposing channels on each side of said female member sufficiently overlap said sides of said male member.
Claim 4
Dependent Claim 21 words
The lock-protecting hasp of claim 1 wherein said space between each rib substantially corresponds geometrically to said shackle of said lock.
Claim 5
Dependent Claim 11 words
The lock-protecting hasp of claim 1 comprising a plurality of ribs.
Claim 6
Dependent Claim 9 words
The lock-protecting hasp of claim 1 comprising eleven ribs.
Claim 7
Dependent Claim 32 words
The lock-protecting hasp of claim 1 wherein said longitudinal slots are of a width slightly larger than said diameter of said shackle of said lock thereby providing for positioning of said shackle.
Claim 8
Dependent Claim 31 words
The lock-protecting hasp of claim 1 wherein said holes comprise elongated holes including an outer radial circumference on each of said holes providing for rotation of said shackle within said hole.
Claim 9
Dependent Claim 49 words
The lock-protecting hasp of claim 1 comprising a protector block affixed to a top end of said leg of said female member adjacent said holes whereby said protector block secures any space between such shackle and said block preventing any prying between said block and body of said lock.
Claim 10
Dependent Claim 24 words
The lock-protecting hasp of claim 1 comprising an offset bend in each leg of said members adjacent the J of each of said members.
Claim 11
Dependent Claim 14 words
The lock-protecting hasp of claim 1 wherein said members are 0.164" hot rolled steel.
Claim 12
Dependent Claim 17 words
The lock-protecting hasp of claim 1 wherein said ribbed locking member and protector block are ductile castings.
Claim 13
Dependent Claim 188 words
Lock-protecting hasp for bars on at least one door and adjacent aligned member comprising: male and female aligned and engageable hasps, each of said hasps including J-shaped structure, two elongated opposing holes in a leg of each of said J for accepting a shackle of a lock and including outer radial circumferences on each of said elongated holes providing for rotation of said shackle of said lock in each said leg, longitudinal opposing slots in said male mating J member and including a longitudinal ribbed locking bar positioned between said slots on the inside of said male J member, longitudinal channels running substantially the length of said female J member on the inside of said female J member to receive the male J member, and a protector block secured to an outer end of an outside of said female J mating member and adjacent said elongated holes whereby said male and female J portion engages over said bars and said ribbed locking bar provides for adjustable securing of said hasps by said lock shackle interlocking with said ribbed member thereby securing said bars of said door and member.
Claim 14
Dependent Claim 188 words
Lock-protecting hasp for bars on at least one door and adjacent aligned member comprising: male and female aligned and engageable hasps, each of said hasps including J-shaped structure, two elongated opposing holes in a leg of each of said J for accepting a shackle of a lock and including outer radial circumferences on each of said elongated holes providing for rotation of said shackle of said lock in each said leg, longitudinal opposing slots in said male mating J member and including a longitudinal ribbed locking bar positioned between said slots on the inside of said male J member, longitudinal channels running substantially the length of said female J member on the inside of said female J member to receive the male J member, and a protector block secured to an outer end of an outside of said female J mating member and adjacent said elongated holes whereby said male and female J portion engages over said bars and said ribbed locking bar provides for adjustable securing of said hasps by said lock shackle interlocking with said ribbed member thereby securing said bars of said door and member.
