Abstract
Abstract A collapsible and lockable hinge joint for elongated members such as a fishing rod. The embodiment disclosed utilizes a unitary, flexible, non-elastic hinge formed of polypropylene which is slotted into ferrules which are attached to adjacent segments of the rod. The junction is preferably completed with the use of a flexible coupling sleeve which slides over the joint. In this manner the entire rod is flexible when in use and does not contain a dead spot at the joint. For use as a fishing rod the segments of the rod can be folded together and clipped for easy storage and transportation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
140 words
In a collapsible elongated member having at least two segments, each of the segments having at least one receiving end, the receiving end having an opening confined entirely therein, an improved hinge joint comprising: retention means for holding two segments in a substantially contiguous, linear relationship to each other so as to form an assembled member with a receiving end from one of the segments abutting a receiving end from the other segment; a unitary, nonelastic, flexible hinge formed from an environmentally stable material, the hinge having an elongated central portion between two ends; and hinge end means integrally formed as part of the hinge ends, the hinge end means securing each end of the hinge to a receiving end of each of the two segments and being freely movable within that portion of the segment adjacent the receiving ends.
Claim 2
Dependent Claim
140 words
In a collapsible elongated member having at least two segments, each of the segments having at least one receiving end, the receiving end having an opening confined entirely therein, an improved hinge joint comprising: retention means for holding two segments in a substantially contiguous, linear relationship to each other so as to form an assembled member with a receiving end from one of the segments abutting a receiving end from the other segment; a unitary, nonelastic, flexible hinge formed from an environmentally stable material, the hinge having an elongated central portion between two ends; and hinge end means integrally formed as part of the hinge ends, the hinge end means securing each end of the hinge to a receiving end of each of the two segments and being freely movable within that portion of the segment adjacent the receiving ends.
Claim 3
Dependent Claim
46 words
The improvement of claim 1 wherein the hinge is molded to have a noncircular cross section; and the opening in the receiving end is an aperture having the same noncircular cross section as the hinge so that the segments are aligned with each other upon assembly.
Claim 4
Dependent Claim
38 words
The improvement of claim 2 wherein the hinge end means comprises compressible tapered protrusions on each end of the hinge constructed so that the hinge may be inserted and removed from the aperture of the segment receiving ends.
Claim 5
Dependent Claim
37 words
The improvement of claims 1 or 2 wherein the hinge end means is removably secured to a receiving end of each of the two segments so that the hinge may be replaced in the event of failure.
Claim 6
Dependent Claim
35 words
The improvement of claim 1 wherein the retention means comprises a sleeve mounted near a receiving end of one of the two segments and into which a receiving end of the other segment is secured.
Claim 7
Dependent Claim
22 words
The improvement of claim 7, wherein the sleeve is flexible so that flexing of the assembled member includes flexing of the sleeve.
Claim 8
Dependent Claim
38 words
The improvement of claim 5 wherein the sleeve is slidably mounted so that the two segments may be aligned and the sleeve slid into place to assemble the collapsible elongated member and to lock the two segments together.
Claim 9
Dependent Claim
20 words
The improvement of claim 7 wherein the sleeve is substantially shorter than the segment to which it is slidably mounted.
Claim 10
Dependent Claim
22 words
The improvement of claim 1 wherein the hinge is molded from a plastic material impervious to gasoline, water, ultraviolet light and sunlight.
Claim 11
Dependent Claim
12 words
The improvement of claim 1 wherein the hinge is molded from polypropylene.
Claim 12
Dependent Claim
98 words
The improvement of claim 3 wherein the retention means comprises a flexible sleeve mounted near a receiving end of one of the two segments and into which a receiving end of the other segment is secured, the sleeve being slidably mounted so that the two segments may be aligned and the sleeve slid into place to assemble the collapsible elongated member and to lock the two segments together, the sleeve being substantially shorter than the segment to which it is mounted; and the hinge is molded from a plastic material impervious to gasoline, water, ultraviolet light and sunlight.
