Abstract

An arm exerciser for runners comprising a hand grip having a peripheral wall, an end wall and a hand grip passage. A tube is received within the hand grip. A weight comprising metal is provided within the tube, and the outer end of the tube is closed.

Claims

1. An arm exerciser for runners comprising:

an elongated enclosure;

said enclosure including a tube and a hand grip having a peripheral wall and an end wall, said tube being received within said hand grip, said end wall having an aperture therein at least a region of the peripheral wall adjacent said end wall being of a size to be manually grasped;

said enclosure having a cavity therein;

a weight comprising metal in said cavity to make the exerciser materially heavier, said weight having a greater density than the enclosure;

a cord with at least a region thereof formed into a loop, said cord extending through said aperture of said end wall; and

means for attaching the cord to the enclosure, said attaching means including said end wall and means on said cord and within said enclosure for cooperating with said end wall.

2. An arm exerciser as defined in claim 1 wherein said aperture communicates with said cavity, said weight includes a plurality of weight elements, at least some of said weight elements being sufficiently small to pass through said aperture, and said cord filling said aperture sufficiently to substantially prevent said weight elements from passing out of said enclosure through said aperture.

3. An arm exerciser as defined in claim 1 wherein said attaching means includes a washer within said enclosure, said washer having an opening therein, said cooperating means includes said cord being tied into a knot, said washer being sandwiched between said knot and said end wall, and said knot being too large to pass through said opening in said washer.

4. An arm exerciser for runners comprising:

a hand grip including a peripheral wall and an end wall, said hand grip having a hand grip passage therein opening at an end of the hand grip opposite said end wall;

a tube having a tube passage therein and inner and outer ends;

said tube being received and retained in said hand grip passage with said inner end being in said hand grip passage;

a weight comprising metal in said tube passage to make the exerciser materially heavier;

closure means for closing the outer end of said tube; and

said outer end being out of said hand grip passage whereby the tube projects beyond the hand grip, said weight includes a plurality of weight elements, said hand grip being constructed of a resilient material and having a plurality of axially spaced radial projections on the exterior thereof to facilitate manual grasping of the hand grip, said tube being constructed of a rigid plastic material, said end wall having an aperture therein, said exerciser including a cord extending through said aperture with at least a portion of said cord lying outside of said hand grip and defining a loop sized to slip over the hand of the user, and means on said cord within said hand grip for cooperating with said end wall to prevent the cord from being withdrawn from the hand grip through said aperture.

5. An arm exerciser as defined in claim 4 wherein at least a portion of said weight lies in the portion of said tube which is outside the hand grip.

6. An arm exerciser as defined in claim 5 including a nonmetallic filler material in said tube passage between the closure means and said weight.
