Exercise harnesses

摘要

An exercise harness has a band (1) that is retained partially encircling the user's head, by a chin-strap (3) and inter-connected head-straps (4). The straps (3, 4) are attached to individual spaced locations of the band (1) by press-studs (6, 7) or two-part fabric fastenings. A cord (13) extending through a pulley-block (14) is clipped at its ends (12) to rings (11) at respective ends of the band (1). Load from a weight or from reaction to head movement is applied to the pulley-block (14) via a swivel connection (15) for equalisation and balancing out of asymmetrical tensioning of the two ends of the band (1) for extension exercise of muscles of the spinal cervix. Unsafe or inappropriate loading causes break-out of one or more of the press-studs (6, 7) or other fastenings to give audible warning of it and a measure of relief.

主权项

1. An exercise harness comprising:
a load bearing band for partial encirclement of a user's head in a loading of muscles associated therewith, wherein said band incorporates two ends and an upper side and a lower side extending lengthwise between said ends; a cord incorporates two opposite ends; said ends of said band being attached to said ends of said cord; said two ends of said band being separated, in use, by an opening; said exercise harness incorporating a pulley system; said cord being secured in said pulley system; a connection extending from said pulley system on which a load is applied in use; said pulley system being provided to equalise tensioning forces applied via said cord to said two ends of said band in loading said muscles; wherein said exercise harness further comprises a chin strap and a plurality of head straps which are in addition to said load bearing band and are sized and shaped to extend over a chin and over the head of the user respectively; said chin strap extending below said lower side and said head straps extending above said upper side of said band; said chin strap and said head straps being disposed in opposite directions; said plurality of head straps each comprising a first end detachably attached to said load bearing band and a second end looped to receive a cord loop; and each of said straps being individually fastened to said band at locations spaced from one another lengthwise thereof by a reattachable two-part press-fastening, said press-fastening comprising two mutually-engaging parts secured to a respective one of said straps and said band which disengage from one another to result in a break-out within an attachment between said strap and said band if inappropriate and unsafe loading exceeding a threshold value is applied to any one or more of said straps and which are reattachable after said break-out.
