The assembly of claim 7 wherein said retaining means comprises a lug extending from said outer wall towards the plane of said inner wall.

Claim 10

The assembly of claim 7 wherein said inner wall is cut away to enable direct contact between said lock body and the first member.

Claim 11

The assembly of claim 7 wherein said element body portion overlaps portions of said inner, side and outer walls when said shackle enters said shackle-receiving aperture.

Claim 12

A shielded lock assembly suitable for joining first and second members together comprising in combination: (A) a shackle-bearing element having a body portion and a shackle carried thereby; (B) a lock body having a keyhole and having a shackle-receiving aperture opening in a given direction and adapted to receive and releasably retain said shackle therein; (C) a housing adapted to be secured to the first member and having an enclosure adapted to receive said lock body and having access openings communicating with said shackle-receiving aperture and said keyhole, respectively, said housing having at least two spaced apart side walls, a back wall joining said side walls, and an outer wall joining said back and side walls, said walls cooperatively defining said enclosure; and (D) means operatively connected to said housing and engageable with said lock body for retaining said lock body in said enclosure; said shackle-bearing element being adapted to be secured to the second member such that said shackle is aligned with and enters said shackle-receiving aperture as the first and second members approach each other, said body portion thereof being configured and dimensioned to then cover substantially all portions of said aperture access opening in said housing not occupied by said shackle, said retaining means comprising a lug extending inwardly from said outer wall at a point spaced forwardly from said back wall.

Claim 13

A shielded lock assembly suitable for joining first and second members together comprising in combination: (A) a shackle-bearing element having a body portion and a shackle carried thereby; (B) a lock body having a keyhole and having a shackle-receiving aperture opening in a given direction and adapted to receive and releasably retain said shackle therein; (C) a housing adapted to be secured to the first member and having an enclosure adapted to receive said lock body and having access openings communicating with said shackle-receiving aperture and said keyhole, respectively, said housing having at least two spaced apart side walls, a back wall joining said side walls, and an outer wall joining said back and side walls, said walls cooperatively defining said enclosure; and (D) means operatively connected to said housing and engageable with said lock body for retaining said lock body in said enclosure; said shackle-bearing element being adapted to be secured to the second member such that said shackle is aligned with and enters said shackle-receiving aperture as the first and second members approach each other, said body portion thereof being configured and dimensioned to then cover substantially all portions of said aperture access opening in said housing not occupied by said shackle, said retaining means comprising a lug extending inwardly from said outer wall at a point spaced forwardly from said back wall.

Claim 14

The assembly of claim 11 wherein said lug is disposed intermediate a pair of said shackle-receiving apertures.

Claim 15

A shielded lock assembly suitable for joining first and second members together comprising in combination; (A) a shackle-bearing element having a body portion and a shackle carried thereby; (B) a lock body having a keyhole and having a shackle-receiving aperture opening in a given direction and adapted to receive and releasably retain said shackle therein; (C) a housing adapted to be secured to the first member and having an enclosure adapted to receive said lock body and having access openings communicating with said shackle-receiving aperture and said keyhole, respectively, said housing having at least two spaced apart side walls, a back wall joining said side walls, and an outer wall joining said back and side walls, said walls cooperatively defining said enclosure; and (D) means operatively connected to said housing and engageable with said lock body for retaining said lock body in said enclosure; said shackle-bearing element being adapted to be secured to the second member such that said shackle is aligned with and enters said shackle-receiving aperture as the first and second members approach each other, said body portion thereof being configured and dimensioned to then cover substantially all portions of said aperture access opening in said housing not occupied by said shackle and to overlap a portion of said side and outer walls of said housing when said shackle enters said shackle-receiving aperture.

Claim 16

A shielded lock assembly suitable for joining first and second members together comprising in combination; (A) a shackle-bearing element having a body portion and a shackle carried thereby; (B) a lock body having a keyhole and having a shackle-receiving aperture opening in a given direction and adapted to receive and releasably retain said shackle therein; (C) a housing adapted to be secured to the first member and having an enclosure adapted to receive said lock body and having access openings communicating with said shackle-receiving aperture and said keyhole, respectively, said housing having at least two spaced apart side walls, a back wall joining said side walls, and an outer wall joining said back and side walls, said walls cooperatively defining said enclosure; and (D) means operatively connected to said housing and engageable with said lock body for retaining said lock body in said enclosure; said shackle-bearing element being adapted to be secured to the second member such that said shackle is aligned with and enters said shackle-receiving aperture as the first and second members approach each other, said body portion thereof being configured and dimensioned to then cover substantially all portions of said aperture access opening in said housing not occupied by said shackle and to overlap a portion of said side and outer walls of said housing when said shackle enters said shackle-receiving aperture.

Claim 17

The assembly of claim 1 wherein said shackle-bearing element is adapted to be secured to the second member and said housing is adapted to be secured to said first member and receive said lock body therein such that the joining of said first and second members together automatically causes said shackle to enter said shackle-receiving aperture and said body portion of said shackle-bearing element to cover substantially all portions of said aperture access opening in said housing not occupied by said shackle, without further manipulation.
