Abstract

An exerciser includes two straps and a handle mounted to an end each strap. A connecting member is mounted to the other end of each strap. The exerciser further includes a suspension member having an inelastic strap. A stop is engaged with an end of the inelastic strap. A retaining ring is engaged with the other end of the inelastic strap. A plurality of rings is fixed to the inelastic strap. The retaining member is releasably engageable with one of the rings, so that the inelastic strap forms a loop. The connecting member is releasably engaged with one of the rings. The inelastic strap is mounted around a rod or the like or extended through a gap between a door and a door frame, allowing user to perform exercises resisting the weight of the user.

Claims

1. An exerciser comprising, in combination:

a connecting member (20) including first and second portions (22, 24);

a linking member (26) including a first linking portion (28) and two second linking portions (30), with the first linking portion (28) engaged with the second portion (24) of the connecting member (20);

two connecting rings (32) engaged with the two second linking portions (30);

two straps (34) each having first and second ends (35, 37), with each of the two straps (34) including first, second, and third sections (36, 38, 40) between the first and second ends (35, 37), with the second section (38) located intermediate the first and third sections (36, 40), with the first end (35) located on an end portion of the first section (36), with the second end (37) located on an end portion of the third section (40), with the first and second sections (36, 48) of each of the two straps (34) hung on one of the two connecting rings (32) with the first section (36) facing a side of the second section (38), with the third section (40) folded onto another side of the second section (38), with the first end (35) of each of the two straps (34) having a spacing to the two connecting rings (32) larger than the second end (37) of the strap (34);

two sleeves (42) each wound around the second and third sections (38, 40) of one of the two straps (34), with each of the two sleeves (42) fixed to the third section (40) of one of the two straps (34), with each of the two sleeves (42) movable along the second section (38) of one of the two straps (34) to move the third section (40) of the strap (34);

two first elements (48) each including a toothed portion (50) and an edge (52) spaced from the toothed portion (50), with each of the two first elements (48) further including a transverse rod (54) between the toothed portion (50) and the edge (52), with the first end (35) of each of the two straps (34) connected to the transverse rod (54) of one of the two first elements (48), with the second and third sections (38, 40) of each of the two straps (34) wound around the toothed portion (50) of one of the two first elements (48);

two second elements (56) respectively and pivotably connected to the two first elements (48), with each of the two second elements (56) including an outer side (58), with each of the two second elements (56) pivotable between a stop position adjacent the toothed portion (50) and a disengagement position distant to the toothed portion (50);

two connecting straps (60) each including two ends (62), with the two ends (62) of each of the two connecting straps (60) connected to the edge (52) of one of the two first elements (52) and the outer side (58) of one of the two second elements (58);

two handles (64) each mounted to one of the two connecting straps (60);

two suspension belts (68) each mounted to one of the two handles (64);

an inelastic strap (74) including first and second ends (76, 78);

a stop (80) engaged with the first end (76) of the inelastic strap (74) and having cross sections larger than the inelastic strap (74);

a plurality of rings (86) fixed to the inelastic strap (74); and

a retaining ring (82) engaged with the second end (78) of the inelastic strap (74);

wherein when either of the two second elements (56) is in the disengagement position, a first spacing between the third section (40) of one of the two straps (34) engaged with the second element (56) and one of the two connecting rings (32) is adjustable by moving one of the two sleeves (42) mounted on the strap (34), a second spacing between one of the two handles (64) associated with the second element (56) to one of the two connecting rings (32) increases when the first spacing decreases,

wherein when the two handles (64) or the two suspension belts (68) are pulled, the two second elements (56) pivot to the stop position, so that each of the two straps (34) is sandwiched and frictionally retained between the toothed portion (50) of one of the two first element (48) and the outer side (58) of one of the two second elements (56),

wherein the first portion (22) of the connecting member (20) is releasably engageable with one of the plurality of rings (86), and

the retaining member (82) is releasably engageable with one of the plurality of rings (86), so that the inelastic strap (74) forms a loop.

2. The exerciser as claimed in claim 1, further comprising, in combination:

a plurality of fixing members (84), with each of the plurality of fixing members (84) folded in two and fixed to a side (79) of the inelastic strap (74) with a space formed between two folded portions of each of the plurality of fixing members (84), with each of the plurality of rings (86) engaged with one of the plurality of fixing members (84) and extended through the space of the fixing member (84).
