Abstract

A weighing device for attaching to the handle of a fish landing net or gaff has a tubular inner housing telescopingly received within a tubular outer housing, with a spring received between an annular collar centrally located on the inner housing and an internal shoulder on the outer housing. An "O" ring located on the side of the collar opposite the shoulder acts as a shock absorber and abuts a retaining ring that limits the travel of the collar in a direction away from the shoulder. A second shoulder spaced from the first shoulder acts to limit movement of the collar toward the first shoulder. A friction retaining adaptor attached at an end of the inner housing secures the net or gaff handle to the inner housing, and scale markings on the other end of the inner housing, which can be zeroed to eliminate the weight of the net or gaff, serve to indicate the weight of the fish.

Dependent claims

A portable scale for mounting on and cooperating with an object to be weighed, comprising:

a tubular outer housing having a central bore with a shoulder annularly positioned therein;
a tubular inner housing having a central bore, said inner housing being coaxially received and confined within said bore of said outer housing for telescoping axial movement with respect thereto and having an annular collar on its outer periphery;
means located between said collar and said shoulder for biasing said collar away from said shoulder;
means for limiting the extent of axial movement of said collar in a direction away from said shoulder;
means for releasably connecting said inner housing to an object received within said bore of said inner housing;
and
means for indicating the extent of axial movement of said inner housing relative to said outer housing;
whereby when said inner housing is secured to the object and said outer housing is restrained, the weight of the object can be determined from the axial movement shown on said indicating means.
