Abstract
A specially designed line marking device includes a marking string that is attached to a bow-shaped support structure with no free end for conveniently use by a single operator, a shuttle for coating the marking string with marking media prior to use, allowing an operator to effectively use this marking device and snap a marking line onto a working surface without the assistance of an additional operator, and a movable carriage containing liquid, powder, or aerosol marking media to be sprayed or deposited along said marking string, creating an inverse image of the marking string.
Claims20
A line marking device comprising:
- a bow-shaped support structure having a first and second ends;
- a continuous marking string slidably attached to said support structure forming a closed loop with no free end, a portion of said marking string extending lengthwise along a shortest distance between said first and second ends of said support structure forming a straight line for producing straight lines on a working surface;
- and
- a shuttle of marking media fixedly attached to said second end of said support structure, said marking string extending through said shuttle of marking media, said marking media impregnating said marking string as said marking string passes through said shuttle of marking media;
- wherein said marking media that is picked up by said marking string is transferred to the working surface to produce straight lines as said marking string is pulled away from the working surface and then released towards the working surface.
A line marking device comprising:
- a bow-shaped support structure having an elongated main body and a first and second curved ends;
- a marking string fixedly attached at both ends to said first and second ends of said support structure forming a lengthwise straight line along a shortest distance between said first and second ends of said support structure for marking a working surface;
- a shuttle carrying a supply of marking media slidably attached to said marking string, said marking string extending through said shuttle and said supply of marking media carried by said shuttle;
- said marking media impregnating said marking string as said shuttle travel back and forth between said first and second ends of support structure;
- and
- wherein said marking media that is picked up by said marking string is transferred to the working surface to produce straight lines as said marking string is pulled away from the working surface and then released towards the working surface.
