Ratcheting strap with take-up reel

Abstract

A ratcheting strap device has an elongate body with a reel axis towards a first end and a ratcheting mechanism towards a second end opposite there-from. The ratcheting mechanism is affixed to the body, and has a spool axis and a ratchet spool rotatable relative to the body there-about. A first strap/hook member has a first length of strap affixed to a first one of the ratcheting mechanism and the body at a first proximal end, and has a first hook affixed to a first distal end there-of. A take-up reel is affixed to the body and rotational relative thereto about the reel axis. A second strap hook member has a second length of strap having a second proximal end connectable to the take-up reel, has a take-up strap portion adjacent to the second proximal end and windable around the take up reel, and has a second hook affixed to a second distal end there-of. The second length of strap has a midsection between its second proximal and distal ends, passing through and engageable by the ratchet spool such that rotation of the spool causes the midsection to be wound there-around.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT

(12) Referring to FIGS. 1 through 8, an exemplary ratcheting strap 100 according to or for use in practicing the invention is disclosed. The ratcheting strap includes a body 101, a short strap/hook 102, a long strap/hook 104, a ratchet mechanism 106, a take-up reel 108 for storing and dispensing the long strap/hook through the ratcheting mechanism, and a hook/loop belt 110 for retaining the ratcheting mechanism and straps/hooks in a compact configuration for storage. The short strap/hook has a proximal end 103 affixed to the body and ratcheting mechanism and a distal end 105 equipped with a hook 107. The long strap/hook has a proximal end 109 connected to the reel and a distal end 111 equipped with a hook 113.

(13) FIG. 1 shows the ratcheting strap in its storage configuration with belt 110 wrapped around the straps/hooks and ratcheting mechanism. The take-up portion 135 of the long strap/hook closest to its distal end is wound around reel 108. Pawl 112 is slidable sideways to lock the reel to prevent it from being rotated relative to body 101 and thereby prevent it from inadvertently dispensing any of the long strap/hook. In FIGS. 2, 4, and 7B, pawl 112 has been slid to its unlocked position, and the crank 114 of the ratcheting mechanism has been swung to its fully opened dispensing condition. By now tugging on the long strap/hook, it causes the reel to rotate relative to the body and dispense the long strap/hook there-from, which passes through slot 116 of the ratcheting mechanism's selectively rotatable spool 118.

(14) The take up reel 108 is a central core 150 with large circular flanges 151A and 151B at both ends. Those flanges have recesses 152 spaced evenly around their perimeters which pass entirely through the thicknesses of the flanges and which are engaged by the pawl when it is slid sideways. By having the recesses in the outer perimeter 153 of the flanges and having them pass entirely through the flanges it gives optimal strength and advantage to the locking feature.

(15) The portion of the long strap/hook that passes through or may be wound around the spool will be referred to as its midsection 125. Of course, that portion will change along the strap as it is dispensed, so the entirety of the long strap/hook between its portion wrapped around the reel and its hooked distal end 111 may serve as the midsection at any given time. When the spool is in the condition of FIG. 5 and has none of the midsection wound around it, the long strap/hook may be freely pulled there-through for dispensing regardless of the crank's position. When some of the midsection is wound around the spool, as seen in FIGS. 6A and 6B, the crank must be swung out to its dispensing position, shown in FIGS. 2, 4, and 7B, to allow the spool to freely rotate so that the long strap/hook may be dispensed. This is made possible by disengagement of the ratchet pawl 133 from the toothed ratchet wheel 115, which is integral with the spool, during the crank's dispensing condition.

(16) When the crank is swung inward as shown in FIGS. 3, 5, 6A, and 7A, the ratchet pawl engages the toothed ratchet wheel and prevents rotation thereof and of the spool except as caused by cranking the crank, so that dispensing of the long strap/hook is denied. When the crank is within that ratcheting range, shown in FIG. 5, pivoting of the crank repeatedly back and forth between the positions shown causes the toothed wheel and spool to rotate in clockwise direction (in that view), and wind the long strap/hook around the spool with great mechanical advantage.

(17) Referring to FIG. 3, with hook 107 hooked onto a first anchoring feature 117 of an automobile or such, the long strap/hook can now be pulled out and passed around an object to be secured (not shown), until it reaches a proper length for its hook 113 to be hooked to a second anchoring feature 119.

(18) Next, the ratcheting mechanism can be activated by swinging the crank in and out within its ratcheting range, as shown in FIG. 7A to pull in and tighten the long strap/hook and tightly secure the object. During this ratcheting, the long strap/hook is wound tightly around spool 118 with great available force to firmly secure the object. The engagement of the crank's ratcheting pawl with the toothed ratchet wheel allows the spool to be rotated by the crank in a tightening direction, but prevents it from rotating in a loosening direction even when the crank is released.

(19) Any slack that may have developed in the long strap/hook between the spool and reel 108 may be taken up by reverse-rotating the reel, then sliding the locking pawl 112 to its locked position to prevent the reel from further rotating in either direction.

(20) Such ratcheting mechanisms including the slotted spool, toothed ratchet wheel, crank, and ratchet pawl are well known and will not be further described herein for brevity, but are exemplified by U.S. Pat. Nos. 5,271,606 and 7,874,047, the entire teachings of which are incorporated herein by reference. Among the advantages of the present invention are the take-up reel and its related features used in conjunction with such a mechanism, for neatly containing the long strap/hook both during use and during storage.

(21) FIG. 9 is an exploded view of ratcheting strap 100.

(22) While the reel is shown in a form that would be wound by hand, an alteration is anticipated in which the reel is spring-loaded like a typical tape measure.

(23) It should be noted that the embodiment shown herein is not intended to limit the scope of the invention. The invention should only be limited by the follow claims, including any equivalent interpretation to which they are entitled.
