Claim 1
Independent Claim
222 words
An improved mechanics creeper, comprising: a fore creeper having two sides, a front end and a rear end, and a conventional castor provided on each of said sides adjacent said front end of the fore creeper; a rear creeper having two sides, a front end and a rear end, and a conventional castor provided on each of said sides adjacent said rear end of the rear creeper; a lower junction edge provided on the front end of the rear creeper, said lower junction edge having two sides and a plurality of holes and a dovetail mortise provided on each of said two sides of the lower junction edge; an upper junction edge provided on the rear end of the fore creeper to correspond to the lower junction edge, said upper junction edge having an inner side, two sides, and a plurality of pillars provided on said inner side of the upper junction edge to be inserted in corresponding holes on the lower junction edge, and a dovetail tenon provided on each of said two sides of the upper junction edge to be inserted in each of said dovetail mortises; wherein assembly of the lower junction edge of the rear creeper with the upper junction edge of the fore creeper forms an integral mechanics creeper which can be disassembled and then assembled anew.
Claim 2
Dependent Claim
222 words
An improved mechanics creeper, comprising: a fore creeper having two sides, a front end and a rear end, and a conventional castor provided on each of said sides adjacent said front end of the fore creeper; a rear creeper having two sides, a front end and a rear end, and a conventional castor provided on each of said sides adjacent said rear end of the rear creeper; a lower junction edge provided on the front end of the rear creeper, said lower junction edge having two sides and a plurality of holes and a dovetail mortise provided on each of said two sides of the lower junction edge; an upper junction edge provided on the rear end of the fore creeper to correspond to the lower junction edge, said upper junction edge having an inner side, two sides, and a plurality of pillars provided on said inner side of the upper junction edge to be inserted in corresponding holes on the lower junction edge, and a dovetail tenon provided on each of said two sides of the upper junction edge to be inserted in each of said dovetail mortises; wherein assembly of the lower junction edge of the rear creeper with the upper junction edge of the fore creeper forms an integral mechanics creeper which can be disassembled and then assembled anew.
Claim 3
Dependent Claim
48 words
An improved mechanics creeper as claimed in claim 1 wherein said lower junction edge further comprises a lower central position having a castor holder adjacent the front end of the rear creeper having a conventional castor which is 2-5mm lower than each of all the foregoing conventional castors.
