Abstract

Abstract A heavy duty load fastener designed to tightly hold bulky materials on a flatbed carrier. The holding device of one embodiment includes a high tensile strength nylon strap having a hook on one end for engaging the edge of a flatbed carrier and a smooth end on the other end for insertion into a ratchet winding mechanism. The winding mechanism is hand operable for securely tightening the nylon strap against the load on the device when in the holding position. The tension on the nylon strap coacts with the ratcheting mechanism to produce a tamperproof lock that cannot be inadvertently released. In another embodiment a high tensile strength nylon strap passes around web supporting surfaces on the load fastener to enable the fastener to securely hold a load together when the load fastener is mounted on the flatbed carrier or to the load.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 250 words
A heavy duty load fastening device, comprising: a housing adaptable for detachably mounting on a carrier, said housing including a first side member and a second side member, said first side member spaced from said second side member to provide an opening between said first side member and said second side member for a chain sprocket wheel; said chain sprocket wheel having a peripheral surface with a plurality of recesses therein for receiving and positively engaging the links of a chain, said chain sprocket wheel rotatably mounted in the space between said first side member and said second side member; a chain holding member, said chain holding member mounted on said first side member and said second side member, said chain holding member located in the space between said first side member and said second side member, said chain holding member having a peripheral surface for holding said chain links in an edgewise position, said chain holding member spaced sufficiently close to said peripheral surface of said sprocket wheel to hold at least one of said chain links securely in at least one of said plurality of recesses in said chain sprocket wheel; a ratchet member rigidly connected to said sprocket and rotatably mounted on said housing; and a pawl mounted on said housing for forming interlocking engagement with said ratchet member to thereby prevent rotation of said ratchet member and said sprocket wheel in at least one direction when said pawl is in interlocking engagement with said ratchet member.
Claim 2
Dependent Claim 250 words
A heavy duty load fastening device, comprising: a housing adaptable for detachably mounting on a carrier, said housing including a first side member and a second side member, said first side member spaced from said second side member to provide an opening between said first side member and said second side member for a chain sprocket wheel; said chain sprocket wheel having a peripheral surface with a plurality of recesses therein for receiving and positively engaging the links of a chain, said chain sprocket wheel rotatably mounted in the space between said first side member and said second side member; a chain holding member, said chain holding member mounted on said first side member and said second side member, said chain holding member located in the space between said first side member and said second side member, said chain holding member having a peripheral surface for holding said chain links in an edgewise position, said chain holding member spaced sufficiently close to said peripheral surface of said sprocket wheel to hold at least one of said chain links securely in at least one of said plurality of recesses in said chain sprocket wheel; a ratchet member rigidly connected to said sprocket and rotatably mounted on said housing; and a pawl mounted on said housing for forming interlocking engagement with said ratchet member to thereby prevent rotation of said ratchet member and said sprocket wheel in at least one direction when said pawl is in interlocking engagement with said ratchet member.
Claim 3
Dependent Claim 35 words
The invention of claim 1 wherein said chain holding member being an idler wheel said idler wheel including a groove for allowing links to pass edgewise between said chain sprocket wheel and said idler wheel.
Claim 4
Dependent Claim 261 words
A heavy duty load fastening device comprising: a housing adaptable for detachably mounting on a carrier, said housing including a first and a second member for rotatably supporting a tiedown engaging member therein having a first tiedown supporting surface at one side of said tie down engaging member, said housing further including a base for supporting said first member and said second member, said base constituting said first tie down supporting surface, a second tiedown supporting surface connecting said first member to said second member at the other side of said tiedown engaging member; said tiedown engaging member including means for rotating said tie down engaging member; a ratchet member rigidly connected to said tie-down engaging member and rotatably mounted on said housing; a pawl mounted on said housing for forming interlocking engagement with said ratchet member to thereby prevent rotation of said ratchet member and said tiedown engaging member in at least one direction when said pawl is in interlocking engagement with said ratchet member; and a tiedown for fastening a load and for engaging said tiedown engaging member, said tiedown engagable with said tiedown supporting surfaces for exerting pressure thereon; said tiedown operable for receiving a tension force by rotation of said tiedown engaging member, said tie down, said tiedown engaging member, and said supporting surfaces coacting so that rotation of said tiedown engaging member causes said tiedown to be placed in tension so that the tension on said tiedown is operable to simultaneously tightly hold a load and maintain said pawl in interlocking engagement with said ratchet member.
Claim 5
Dependent Claim 261 words
A heavy duty load fastening device comprising: a housing adaptable for detachably mounting on a carrier, said housing including a first and a second member for rotatably supporting a tiedown engaging member therein having a first tiedown supporting surface at one side of said tie down engaging member, said housing further including a base for supporting said first member and said second member, said base constituting said first tie down supporting surface, a second tiedown supporting surface connecting said first member to said second member at the other side of said tiedown engaging member; said tiedown engaging member including means for rotating said tie down engaging member; a ratchet member rigidly connected to said tie-down engaging member and rotatably mounted on said housing; a pawl mounted on said housing for forming interlocking engagement with said ratchet member to thereby prevent rotation of said ratchet member and said tiedown engaging member in at least one direction when said pawl is in interlocking engagement with said ratchet member; and a tiedown for fastening a load and for engaging said tiedown engaging member, said tiedown engagable with said tiedown supporting surfaces for exerting pressure thereon; said tiedown operable for receiving a tension force by rotation of said tiedown engaging member, said tie down, said tiedown engaging member, and said supporting surfaces coacting so that rotation of said tiedown engaging member causes said tiedown to be placed in tension so that the tension on said tiedown is operable to simultaneously tightly hold a load and maintain said pawl in interlocking engagement with said ratchet member.
Claim 6
Dependent Claim 11 words
The invention of claim 3 wherein said tiedown includes a web.
Claim 7
Dependent Claim 23 words
The invention of claim 4 wherein said tiedown engaging member includes a detachable handle for applying a torque to said tiedown engaging member.
Claim 8
Dependent Claim 34 words
The invention of claim 5 wherein said web has a thickness one-half a and said tiedown engaging member includes an elongated opening therein having an opening for receiving two webs of thickness one-half a.
Claim 9
Dependent Claim 21 words
The invention of claim 6 wherein said carrier is a flatbed carrier having at least two load fastening devices located thereon.
Claim 10
Dependent Claim 22 words
The invention of claim 6 wherein said load fastening device includes nylon web having a tensile strength of at least 24,000 pounds.
