Abstract
A tie down capable of sustaining a load includes a drum assembly having an axle and a pair of drum wheels, a pair of slots, a pair of ratchets having gear teeth, and a pawl having a pair of flanges. One of the pair of flanges correspondingly engages in one of the pair of slots disposed within each of the pair of drums. The flanges of the pawl can simultaneously disengage from between the gear teeth of each of the pair of ratchets or simultaneously engage between the gear teeth of each of the pair of ratchets to selectively constrain rotation of the pair of ratchets.
Claims16
An apparatus, comprising:
- a drum assembly including:
- an axle having a slit disposed within an axle sidewall;
- a pair of drum wheels correspondingly coupled to distal ends of said axle with said slit disposed between said pair of drum wheels;
- a pair of slots, one of said pair of slots disposed within each of said pair of drum wheels;
- a pair of ratchets having at least two gear teeth, one of said pair of ratchets coupled to each of said distal ends of said axle adjacent an outward facing side of each of said pair of drum wheels;
- and
- a pawl having a pair of flanges, one of said pair of flanges correspondingly slidably engaged in one of said pair of slots disposed within each of said pair of drums, said pair of flanges of said pawl simultaneously slidably engageable between said at least two gear teeth of each of said pair of ratchets to selectively constrain rotation of said pair of ratchets.
An apparatus, comprising:
- a ratchet tensioner comprising:
- an axle rotatably mounted between a pair of drum wheels;
- at least one ratchet having at least two gear teeth, said at least one ratchet fixedly mounted to said axle on an outward side of said pair of drum wheels;
- a pawl having a pair of flanges, each one of said pair of flanges correspondingly slidably engageable with each one of a pair of slots disposed within each of said pair of drum wheels, said pair of flanges of said pawl simultaneously slidably engageable between said at least two gear teeth of said at least one ratchet to selectively constrain rotation of said at least one ratchet;
- a spring operated pinching member in cooperative engagement with said pawl, said spring operated pinching member fixedly attached to said pair of drum wheels in parallel alignment with said axle;
- a first strap having a first end removably anchored to said axle, a second end oppositely disposed from said first end, and an elongate member between said first end and said second end, said elongate member of said first strap extendable in a first direction away from said axle, and
- a second strap, said second strap secured to a tether member on a first end, said tether member coupled to said ratchet tensioner to introduce said second strap in a second direction opposite said first strap.
An apparatus, comprising:
- a length of first strap, said first strap comprising a distal end having a hook;
- an axle configured to spool said length of said first strap, said first strap comprising a proximal end removably anchored to said axle;
- a first ratchet wheel and a second ratchet wheel oppositely disposed on distal ends of said axle;
- said first ratchet wheel and said second ratchet wheel coupled in a cooperating rotating relationship with one another relative to said axle;
- said first ratchet wheel and said second ratchet wheel comprising a plurality of teeth extending radially from each perimeter of each of said first ratchet wheel and said second ratchet wheel;
- a pawl having a pair of flanges, each one of said pair of flanges correspondingly slidably engageable with each one of a pair of slots, each of said pair of slots formed within a sidewall of a first drum wheel and a second drum wheel;
- said first drum wheel and said second drum wheel oppositely disposed on said distal ends of said axle with said first ratchet wheel and said second ratchet wheel disposed on an outward face of said each sidewall of said first drum wheel and said second drum wheel;
- a second strap releasably secured to a tether member, said tether member removably mounted between a plurality of radial spokes formed within said each sidewall of said first drum wheel and said second drum wheel;
- and
- a spring-loaded member in cooperative engagement with said pawl, wherein said spring-loaded member in a releasably biased relationship with said pair of flanges of said pawl to selectively constrain said plurality of teeth of each of said first ratchet wheel and said second ratchet wheel.
