Abstract

An exercising apparatus constituting an oblong housing having handles at opposite ends that are interconnected by a shock cord which extends through the housing being looped internally of the housing by passage back and forth between sheaves adjacent opposite ends of the housing so that the length of the cord between the handles in idle condition of the apparatus is several times the distance between the handles in the latter'"'"'s idle position whereby a greater length of shock cord is available for stretching from idle condition than would be available if the shock cord directly connected the handles without such looping.

Claims

1. A compact portable exercising apparatus, comprising:

(a) a housing elongated along a longitudinal axis and having opposite end regions;

(b) retroverting means mounted within the housing and including a first plurality of pulleys at one end region of the housing and mounted for joint rotation about, and axially arranged in side-by-side relationship along, a first pulley axis which extends generally normal to the longitudinal axis, and a second plurality of pulleys at the other end region of the housing and mounted for joint rotation about, and axially arranged in side-by-side relationship along, a second pulley axis which extends generally normal to the longitudinal axis, said first and second pulley axes being in mutual parallelism and spaced apart by a predetermined distance along the longitudinal axis;

(c) a pair of handles located exteriorly of the housing and having handle passages extending through the handles; and

(d) an elongated resiliently extensible endless rope having external rope portions extending through the handle passages and internal rope portions looped back and forth between the first and second pluralities of pulleys generally along the longitudinal axis, said endless rope being stretchable between

(i) an idle position in which the rope is under low tension and urges the handles into mutual parallelism at the end regions of the housing, and

(ii) a use position in which the rope is under high tension and resists an exerciser from moving the handles apart from each other over a distance greater than said predetermined distance.

2. The apparatus as recited in claim 1, wherein the housing has planar top and bottom walls spaced apart from each other in mutual parallelism, said top wall having at each of said end regions of the housing a first wall section extending generally perpendicularly of the plane of the top wall toward the bottom wall, and a second wall section extending generally parallel to the plane of the top wall, each first and second wall section extending transversely over at least part of each end region and together bounding a niche in which a respective handle is entirely received in the idle position.

3. The apparatus as recited in claim 1, wherein the housing has entrance and exit holes through which the rope passes, said holes being formed at each end region within each niche.

4. The apparatus as recited in claim 1, wherein each plurality of pulleys includes two colinear pairs of three pulleys, each pair constituting a sub-set;

and wherein a first sub-set of the first plurality is juxtaposed with a first sub-set of the second plurality; and

wherein the internal loop portions include a first loop entrained about the first sub-sets of each plurality; and

wherein a second sub-set of the first plurality is juxtaposed with a second sub-set of the second plurality; and

wherein the internal loop portions include a second loop entrained about the second sub-sets of each plurality; and

further comprising a rib extending between the first and second loops for preventing the former and the latter from entangling with each other during stretching.

5. The apparatus as recited in claim 1, wherein the housing has a generally parallelepiped shape whose external dimensions are less than 16 inches in length, 11 inches in width and one inch in depth.
