Abstract
Abstract A strap adjusting and tensioning assembly includes a frame or body portion carrying a drum for holding the adjusted portion of the strap. Ratchet wheels are connected to the drum and a holding pawl member is mounted in the frame and is engageable with the ratchet teeth. A movable handle having a second pawl member mounted thereon is supported on the body for movement therewith. The handle pawl is formed with a portion which engages the wrapped strap when the strap is wrapped up to give a predetermined diameter after take up by movement of the handle. The frame pawl is shaped to be clear of the wrapped strap surface to provide a condition where the wrapped strap diameter causes the handle pawl to disengage from the ratchet teeth while the frame pawl member remains in holding engagement with the teeth.

Claim 1
Independent Claim
221 words
In a strap adjusting and tensioning device having a frame assembly and a handle assembly swingably supported on said frame assembly, a. said frame assembly including, 1. a frame structure having a pair of frame side members spaced to accommodate a strap member between them, 2. a wind-up drum rotatably mounted on said side members, said drum providing for holding several wraps of strap for length adjustment and tensioning purposes, 3. a pair of ratchet wheels each having a plurality of teeth, one of which wheels is connected near each end of said drum for rotational movement and positioned generally adjacent a side member, 4. a frame supported holding pawl member slidably movable with respect to said frame structure in a generally radial direction relative to said ratchet wheels and spring loaded to bear against the ratchet, said frame pawl member having a body section and a pair of spaced legs extending therefrom, said legs extending respectively along each of the frame slide members to engage the teeth of a ratchet wheel, and said body section spanning the strap holding portion of the wind-up drum; b. said handle assembly including: 1. a pair of handle side members, one located adjacent each of said frame side members, said handle side members being pivotally supported for rotation about the axis of the drum,

In a strap adjusting and tensioning device having a frame assembly and a handle assembly swingably supported on said frame assembly, a. said frame assembly including, 1. a frame structure having a pair of frame side members spaced to accommodate a strap member between them, 2. a wind-up drum rotatably mounted on said side members, said drum providing for holding several wraps of strap for length adjustment and tensioning purposes, 3. a pair of ratchet wheels each having a plurality of teeth, one of which wheels is connected near each end of said drum for rotational movement and positioned generally adjacent a side member, 4. a frame supported holding pawl member slidably movable with respect to said frame structure in a generally radial direction relative to said ratchet wheels and spring loaded to bear against the ratchet, said frame pawl member having a body section and a pair of spaced legs extending therefrom, said legs extending respectively along each of the frame slide members to engage the teeth of a ratchet wheel, and said body section spanning the strap holding portion of the wind-up drum; b. said handle assembly including: 1. a pair of handle side members, one located adjacent each of said frame side members, said handle side members being pivotally supported for rotation about the axis of the drum,
Claim 3
Dependent Claim
197 words
A handle supported adjusting pawl member slidably movable with respect to the handle in a generally radial direction relative to said ratchet wheels, and spring-loaded to bear against the ratchet, said handle pawl member having a body section and a pair of spaced legs extending therefrom, said legs extending respectively along each of the handle side members to engage the teeth of a ratchet wheel, and said body section spanning the strap holding portion of the wind-up drum; The improvement characterized in that the radially innermost edge portion of the frame pawl body section spanning the windup drum is offset on a larger radius from the drum axis than the radially innermost edge portion of the handle pawl body section spanning the wind-up drum, whereby when a strap wound about the drum builds up to a diameter such That it engages the radially innermost edge portion of the handle pawl body section it will cause the handle pawl to move out of engagement with the ratchet teeth, thereby making handle movement ineffective for further wind-up of the strap but without simultaneously causing disengagement of the frame pawl from the ratchet wheels and consequent loss of strap tension.
Claim 4
Dependent Claim
197 words
A handle supported adjusting pawl member slidably movable with respect to the handle in a generally radial direction relative to said ratchet wheels, and spring-loaded to bear against the ratchet, said handle pawl member having a body section and a pair of spaced legs extending therefrom, said legs extending respectively along each of the handle side members to engage the teeth of a ratchet wheel, and said body section spanning the strap holding portion of the wind-up drum; The improvement characterized in that the radially innermost edge portion of the frame pawl body section spanning the windup drum is offset on a larger radius from the drum axis than the radially innermost edge portion of the handle pawl body section spanning the wind-up drum, whereby when a strap wound about the drum builds up to a diameter such That it engages the radially innermost edge portion of the handle pawl body section it will cause the handle pawl to move out of engagement with the ratchet teeth, thereby making handle movement ineffective for further wind-up of the strap but without simultaneously causing disengagement of the frame pawl from the ratchet wheels and consequent loss of strap tension.
Claim 5
Dependent Claim
24 words
a wind-up drum rotatably mounted on said side members, said drum providing for holding several wraps of strap for length adjustment and tensioning purposes,
Claim 6

a wind-up drum rotatably mounted on said side members, said drum providing for holding several wraps of strap for length adjustment and tensioning purposes,
Claim 7
Dependent Claim

A handle supported adjusting pawl member slidably movable with respect to the handle in a generally radial direction relative to said ratchet wheels, and spring-loaded to bear against the ratchet, said handle pawl member having a body section and a pair of spaced legs extending therefrom, said legs extending respectively along each of the handle side members to engage the teeth of a ratchet wheel, and said body section spanning the strap holding portion of the wind-up drum; The improvement characterized in that the radially innermost edge portion of the frame pawl body section spanning the wind-up drum is offset on a larger radius from the drum axis than the radially innermost edge portion of the handle pawl body section spanning the wind-up drum, whereby when a strap wound about the drum builds up to a diameter such That it engages the radially innermost edge portion of the handle pawl body section it will cause the handle pawl to move out of engagement with the ratchet teeth, thereby making handle movement ineffective for further wind-up of the strap but without simultaneously causing disengagement of the frame pawl from the ratchet wheels and consequent loss of strap tension.
Claim 8
Dependent Claim
