Strap Tensioning Assembly
First Claim
1. A strap tensioning assembly comprising:
- a frame including two lateral walls spaced from and parallel with each other, with each lateral wall including a perimeter defining a first, a second, and a third engaging sections, an axle having two ends mounted on the two lateral walls respectively and being rotatable, an automatic reeling device mounted on the axle, a first detent having two lateral sides biasably mounted on the two lateral walls respectively, and a brake mechanism biasably mounted between the two lateral walls;
a ratcheting device including a spool mounted on the axle and rotatable with the axle, a ratchet wheel mounted on the spool, with the ratchet wheel selectively engaged with the first detent, and with ratchet wheel selectively engaged with the brake mechanism; and
an operating device includes a pivotal end pivotally mounted on the axle, with the pivotal end including a perimeter defining a first, a second, and a third cams, with the first cam selectively urging the first detent away from the ratchet wheel, and with the second and third cams selectively urging the braking mechanism away from the ratchet wheel, a locking member selectively engagable with the first, second and third engaging sections of each lateral wall, and with the locking member selectively engaged with the ratchet wheel; and
wherein the locking member is engaged in the first engaging section, the ratchet wheel is engaged by the locking member, the brake mechanism is urged away and disengaged from the ratchet wheel by the second cam, and the ratchet wheel is rotated in a first direction upon reciprocal pivoting of the operating device in the first engaging section in order to tension and collect a strap; and
wherein the locking member is disengaged from the ratchet wheel and engaged in the second engaging section, the brake mechanism is urged away and disengaged from the ratchet wheel by the second cam, and the first detent is selectively disengaged from the ratchet wheel upon pivoting of the operating device in the second engaging section in order to release a strap; and
wherein the locking member is disengaged from the ratchet wheel and is engaged in a first position of the third engaging section, the first detent is urged to disengage from the ratchet wheel by the first cam, the brake mechanism is engaged with the ratchet wheel, the ratchet wheel is rotated in the first direction by the automatic reeling device without maneuvering the operating device, and the brake mechanism provides resistance to slow down rotation speed of the ratchet wheel; and
wherein the locking member is engaged in a second position of the third engaging section, the first detent is urged to disengage from the ratchet wheel by the first cam, the brake mechanism is urged away and disengaged from the ratchet wheel by the third cam, and the ratchet wheel is rotated without resistance from the brake mechanism.

Abstract
A strap tensioning assembly includes a frame having two lateral walls and each of which includes a perimeter defining a first, a second, and a third engaging sections, an axle, and an automatic reeling device. A ratcheting device is mounted on and is rotatable with the axle and includes a ratchet wheel selectively engaged with a first detent as well as a brake mechanism. An operating device includes a pivotal end mounted on the axle and including a first, a second, and a third cams, and a locking member selectively engagable with the first, second and third engaging sections. The operating device is pivoted in the first engaging section in order to tension a strap, and is pivoted in the second engaging section in order to release a strap, and is adapted to be rotated by the automatic reeling device, and under or without resistance imposed by the braking mechanism.
