An exercise device has a pair of axially spaced reels 102a, 102b, which are each biased by a spiral spring 108. Each reel is attached to one end of a respective strap 130a, 130b and an outer end of each strap is attached to a carabiner 134a, 34b. Each reel is selectably releaseable by a locking arrangement 112a, 112b, 16, 117, that is able to interfere with rotation of the reels 102a, 102b, in dependence upon action by a user. Each reel is independently rotatable and each strap 130a, 130b may be extended or retracted independently of one another. Using the carabiners 134a, 134b, each strap may be secured to an attachment 10 beam so that the straps form a V-configuration and it is envisaged that two such exercise devices may be used so that a user may perform exercises such as push-ups, triceps dips, back pulls and pull-ups. Non-suspended exercises may be performed by providing rubber feet 127a, 127b, and two such exercise devices may be connected together by interconnecting male 123a and female connectors 124b.
An exercise device including a pair of axially spaced rotatable reels having axes in spaced apart planes, spring means arranged to bias each said reel in a direction of rotation, each said reel having associated therewith an inelastic strap, and selectably releaseable locking means arranged to release and lock said reels from rotation, wherein each said reel is arranged to extend a respective one of said straps against the bias of said spring means or to rewind said strap about a respective reel under the influence of said spring means, and also wherein the reels and locking means are located within a casing, said casing being generally dumbbell-shaped with the reels being longitudinally axially spaced apart and each located in a drum-shaped end, and said drum-shaped ends being interconnected by a member forming a handle, said casing being provided in two longitudinally conjoined halves, the reels and locking means being located between the two halves and the spring means being located in an outer portion of each drum-shaped end.
An exercise device including a pair of axially spaced rotatable reels having axes in spaced apart planes, spring means arranged to bias each said reel in a direction of rotation, each said reel having associated therewith an inelastic strap, and selectably releaseable locking means arranged to release and lock said reels from rotation, wherein each said reel is arranged to extend a respective one of said straps against the bias of said spring means or to rewind said strap about a respective reel under the influence of said spring means, each said reel comprising a single sprocket wheel toward one end of an axle about which said strap is wound and said reel has a longitudinally extending diametric slot therein and the axle, said associated strap being inserted through the slot and secured in overlapping manner about the axle, and also wherein the locking means comprises the sprocket wheel attached to the reel and a spring biased manually operable shaft slideably mounted in a barrel, said shaft and barrel each having a cut-out therein disposed along a longitudinal axis thereof, said cut-outs having a width greater than a width of the sprocket wheel, whereby the sprocket wheel is arranged to locate through the cut-out in the barrel, and the shaft has at least a portion thereof having a full diameter sufficient to locate between teeth of the sprocket wheel, and translational motion of the shaft within the barrel permits the sprocket wheel to rotate within the cut-outs of the barrel and shaft, or to have rotation thereof arrested by said full diameter of the shaft engaging between adjacent teeth of the sprocket wheel.
