(16) FIGS. 1-4 show a first embodiment of the tie strap 10 comprising a head 20 formed on a first end, a body 30 formed on a medial region, and a tail 40 formed on a second end. In alternate embodiments not illustrated the tie strap 10 may include multiple heads 20, bodies 30, and tails 40.

(17) The head 20 comprises a plurality of similarly dimensioned head apertures 22 extending through the entire head thickness 21. Each head aperture 22 has a head aperture height 23 along its minor dimension and a head aperture width 24 along its major dimension. The head thickness 21 is defined adjacent to the head apertures 22.

(18) Although not illustrated, additional apertures of arbitrary size and shape may be present, such as a small circular aperture for hanging the tie strap 10 on a nail or pegboard hook. Furthermore, although head apertures 22 are illustrated as narrow slots with rounded ends, any aperture shape suitable for coupling with a body 30 may be used. Finally, although a uniform head thickness 21 is illustrated, varying head thickness 21 may be advantageous, for example to accommodate varying separations between some ridge pair 33a and an adjacent ridge pair 33b.

(19) The body 30 generally comprises a plurality of ridge pairs 33a. Each ridge pair 33a comprises a first ridge 33 disposed on a first lateral surface 11x and a second ridge 33 disposed on an opposite second lateral surface 11y, wherein ridges 33 are oriented transversely to the longitudinal axis of the tie strap 10 and protrude laterally from the body 30. Although not illustrated, ridges 33 disposed on only one lateral surface 11 may be advantageous in some circumstances. Also, although only equally spaced ridge pairs 33a have been illustrated, it may be advantageous to space them unequally. Close spacing between some ridge pair 33a and ridge pair 33b near the head 20 permits fine-grained strapping adjustments where precision matters, for example when the tie strap 10 is secured to a small-diameter object. Similarly, far spacing between some ridge pair 33a and ridge pair 33b near the tail 40 permits coarse-grain adjustments where precision is less important, for example when the tie strap 10 is secured to a large-diameter object.

(20) The body 30 has a body thickness 31 substantially equal to the head aperture height 23 (short dimension) and a body width 32 substantially equal to the head aperture width 24 (long dimension) to permit insertion of the body 30 through a head aperture 22. The body thickness 31 is defined between some adjacent ridge pair 33a and ridge pair 33b.

(21) The tail 40 defines a tail thickness 41 that is less than the head aperture height 23 to enable easy insertion through a head aperture 22. The tail width 42 may be smaller than the head aperture width 24, or the tail 40 may have a generally tapered shape, to further simplify insertion of the tail 40 through a head aperture 22.

(22) FIG. 3 shows a perspective view of the tie strap 10 with the body 30 coupled to the head 20 through one of the head apertures 22. A user may couple the body 30 to the head 20 by: (1) inserting the tail 40 through a head aperture 22; (2) gripping the tail 40; and (3) pulling the tail 40 (and body 30) until at least one ridge pair 33a has traversed through the head aperture 22. A plurality of embossed elements 43 may be disposed on the tail 40 to facilitate easier gripping.

(23) FIG. 4 shows an example application in which the tie strap 10 is semi-permanently secured to a first object by coupling the body 30 to a first head aperture 22. In FIG. 4a, the body 30 is wrapped around a second object but not yet secured thereto. In FIG. 4b, the tie strap 10 is secured to the second object by coupling the body 30 to a second head aperture 22. Although the body 30 can be readily decoupled from the second head aperture 22, inserting and withdrawing the body 30 through the second head aperture 22 can be slow. Also, the ridges 33 can eventually wear out from repeated insertions and withdrawals. FIG. 4c shows how the tie strap 10 can be secured to the second object by means of a catch mechanism 50 protruding axially from the distal end of the head 20. The catch lip 51 of the catch mechanism 50 may be inserted through a body aperture 34 to hold the tie strap 10 in place around the second object.

(24) FIG. 5 shows the catch mechanism 50 in greater detail. The catch mechanism 50 may be made of metal, plastic, or any other material or materials having suitable strength. As shown in FIG. 1, the catch mechanism 50 may swivel or rotate to accommodate various strapping applications or to enable more compact stowage of the tie strap 10, for example when several tie straps 10 are stacked and bundled for retail packaging. FIG. 5b and FIG. 5c show an example swivel mechanism comprising a flanged housing adapted to receive a bulbous base of a hook member.

(25) FIG. 5a and FIG. 5d show the catch mechanism 50 anchored to the tie strap 10 by means of a catch anchoring mechanism 52. In this first embodiment, the catch anchoring mechanism 52 comprises a pair of plates positioned on opposite lateral surfaces 11. Further, the catch anchoring mechanism 52 may comprise one or more inwardly oriented anchoring teeth 53 as shown in FIG. 5e and FIG. 5f. Each anchoring tooth 53 may either rest against a lateral surface 11 or pierce partially or completely therethrough. Consequently, the catch anchoring mechanism 52 may be molded in place with a tie strap 10 or it may be pressed or clamped onto a molded tie strap 10 like a pair of jaws.

(26) Although each body aperture 34 need only have shape and dimensions that are complementary with the catch mechanism 50 (for example circular body apertures 34 as shown in FIG. 13), making the shape and dimensions also complementary with the shape and dimensions of the body 30 permits the body apertures 34 to engage with the body 30 as shown in FIG. 6. If engagement of body apertures 34 with the body is desired, the body aperture height 35 (short dimension) should by substantially equal to the body thickness 31 and the body aperture width 36 (long dimension) should be substantially equal to the body width 32.

(27) FIG. 7 shows a second embodiment of the tie strap 10 wherein the catch mechanism 50 comprises a cylindrical post protruding axially from the distal end of the head 20. The catch mechanism 50 has a bulbous catch lip 51 for coupling to a body aperture 34. FIG. 8 shows the catch mechanism 50 in greater detail. The catch mechanism 50 may be made of metal, plastic, or any other material or materials having suitable strength. In this second embodiment, the catch mechanism 50 is molded in place with the tie strap 10. Consequently, the anchoring mechanism 52 may comprise: (1) fusion of the tie strap 10 material with the catch mechanism 50 material; (2) friction between adjacent surfaces of the tie strap 10 and catch mechanism 50; and (3) anchoring of tie strap 10 material that may have lodged within holes, groves, or recesses in the catch mechanism 50 during molding, such as the anchoring holes 54 shown in FIG. 8b and FIG. 8d.

(28) FIG. 9 shows an example application of the second embodiment in which the tie strap 10 is semi-permanently secured to a first object by coupling the body 30 to a first head aperture 22. In FIG. 9a, the body 30 is wrapped around a second object but not yet secured thereto. In FIG. 9b, the tie strap 10 is secured to the second object by coupling the catch mechanism 50 to a body aperture 34. The catch lip 51 is adapted to readily pass through the body aperture 34 in the direction of insertion and to resist passing through the body aperture 34 in the direction of withdrawal.

(29) FIG. 10 shows a third embodiment of the tie strap 10 wherein the catch mechanism 50 comprises a cylindrical post protruding transversely from the distal end of the head 20. The catch mechanism 50 has a bulbous catch lip 51 for coupling to a body aperture 34. FIG. 11a shows the tie strap 10 prior to coupling of the catch mechanism 50 to a body aperture 34; FIG. 11b shows the tie strap 10 with the catch mechanism 50 coupled to a body aperture 34.

(30) FIG. 12 shows a fourth embodiment of the tie strap 10 wherein the catch mechanism 50 comprises a grapple hook protruding axially from the distal end of the head 20. As in the first embodiment, the catch mechanism 50 may swivel. Further, the catch mechanism 50 may be bifurcated, trifurcated, and so on.

(31) Finally, FIG. 13 shows a fifth embodiment of the tie strap 10 wherein the body apertures 34 have shape and dimensions complementary with the catch mechanism 50 but not complementary with the body 30. A tie strap 10 configuration as shown in FIG. 6 is not possible with this fifth embodiment.

(32) Although tie straps 10 may be manufactured in various lengths, widths, and thicknesses to suit particular applications, it should be appreciated that tie straps 10 having compatible dimensions may permit chaining to increase the effective strapping length.

(33) Many modifications, configurations, and features may be evident that do not depart from the spirit and scope of the several embodiments of this disclosure. Although specific embodiments have been illustrated and described, it should be understood that the embodiments are exemplary, non-exhaustive, and should not limit the scope of the several embodiments of this disclosure as defined by the appended claims.
