DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(15) In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part hereof, and within which are shown by way of illustration specific embodiments by which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the invention.

(16) In a general embodiment the novel releasable ratchet strap having a lock mechanism can have a lock and key system. It is within the scope of this invention for a key to include, but not be limited to, a passcode, a combination, a digital code, a numerical code, a finger print identification system, a password system, a visual identification system, or a turn-key. An authorized user includes, but not limited to, an individual having the key or passcode to the keyed lock. In a preferred embodiment, an authorized user will use the key or passcode which enables the lock mechanism to orient at least one recess of the lock pin to align with a portion of the latch. This recess creates clearance for a portion of the latch to be depressed by a user to release the latch tooth of the lever from engaging a strap tooth of the releasable ratchet strap.

(17) In a preferred embodiment, the latch of the releasable ratchet strap having a lock mechanism has a length great enough for a user to depress an end of the latch. More particularly, when the lock mechanism is positioned in a locked orientation, the latch tooth of the lever is positioned between a primary strap tooth and a secondary strap tooth. When a portion of the latch is located within a recess of the lock pin, the latch tooth of the lever is disengaged from the interconnection between a primary strap tooth and a secondary strap tooth of the releasable ratchet strap. In an alternate embodiment, the latch tooth engages a portion of at least one strap tooth.

(18) In another embodiment, the releasable ratchet strap having a lock mechanism can have a robust flexible inner core made of a material including, but not limited to steel or carbon fiber. A steel core being located within a releasable ratchet strap having a lock mechanism can prevent an unauthorized user from cutting through the ratchet strap. It is within the scope of this invention for the releasable ratchet strap having a lock mechanism to be made of a flexible metal material.

Construction of the Novel Releasable Ratchet Strap

(19) It will now be seen, referring to FIGS. 1-3, novel releasable ratchet strap having a lock mechanism 1 includes lock housing 2. Lock housing 2 retains components of lock mechanism 20 (FIGS. 2 and 3). Lock housing 2 has primary compartment 3. Primary compartment 3 can have primary compartment opening 8 (FIGS. 2-4). Lock pin 4 is retained by primary compartment 3. Secondary compartment 19 retains lock cam 17 (FIGS. 2-4). A releasable ratchet strap having a lock mechanism 1 has ratchet strap 9. Ratchet strap 9 has a surface having at least one strap tooth 10. Latch 11 has primary end 12 having latch tooth 18 located opposite latch 11 secondary end 13. Secondary end 13 of latch 11 is configured to be depressed 2 (FIG. 1B) by a user (not shown). FIGS. 1B and 3 depicts lock mechanism positioned in an unlocked orientation. In this unlocked orientation, latch 11 can be depressed because recess 14 of lock pin 4 is in alignment with latch 11. FIG. 1B shows the force 21 applied to latch 11 secondary end 13 which pivots latch 11 on recessed portion 14 of lock pin 4. Lock pin 4 is oriented in a locked orientation in FIGS. 1A-2 when no recess of the lock pin is in alignment with a portion of the latch. Lock pin 4 obstructs latch 11 from hingedly pivoting and cannot release latch tooth 18 of lever 11 from contact with strap tooth 10 of ratchet strap 9.

(20) FIG. 1A illustrates ratchet strap 9 having a proximal end 34A located opposite a distal end 34B. Lock housing 2 is connected to proximal end 34A of ratchet strap 9. Lever 11 is hingedly connected to lock housing 2. Ratchet strap 9 has robust flexible inner core 25 (FIGS. 1A-3). An end of ratchet strap 9 can be connected to primary anchor structure 26A. In an alternate embodiment illustrated in FIGS. 1A and 1B, primary anchor structure 26A can connect flexible inner core 25 of ratchet strap 9 to lock housing 2.

(21) FIG. 1B shows lock pin 4 being oriented in an unlocked orientation when at least one recess 14 (FIGS. 1B-4) of lock pin 4 is in alignment with a portion of latch 11. Latch 11 can hingedly pivot when the force 21 of a user (not shown) depresses an end 13 of latch 11. When lever 11 is depressed by a user, latch tooth 18 of lever 11 is released from contact with strap tooth 10 of the ratchet strap 9.

(22) FIGS. 1-3 depict ratchet strap 9 of releasable ratchet strap having a lock mechanism 1 being substantially flat with one side of ratchet strap 9 having plurality of strap teeth 10.

(23) FIGS. 2 and 3 depict primary compartment 3 retaining lock pin 4 and resilient member 7. Primary compartment 3 also retains a portion of lock jam ball 15. Lock pin 4 has primary end 5 located opposite secondary end 6. Secondary end 6 of lock pin 4 is in communication with resilient member 7. It is within the scope of this invention for resilient member 7 to include, but not be limited to, a spring. FIG. 2 illustrates primary end 5 of lock pin 4 protruding from primary compartment opening 8 (FIGS. 2 and 3) of lock housing 2. In an example, a user could depress 22 (FIG. 2) primary end 5 of lock pin 4 to engage lock jam ball 15 within recess 14 of lock pin 4 to position the lock mechanism in a locked orientation. In another example, a user could turn 23 a key 16 to position the lock mechanism in a locked orientation.

(24) FIG. 2 shows lock pin 4 being positioned in a locked orientation when no recess of lock pin 4 is in alignment with a portion of latch 11. Lock pin 4 obstructs latch 11 from hingedly pivoting and prevents the release of contact between latch tooth 18 of lever 11 and strap tooth 10 of the ratchet strap 9.

(25) FIG. 3 shows key 16 being turned 23 to position lock mechanism 20 in an unlocked orientation. The force of resilient member 7 abutting lock pin 4 allows lock pin 4 to traverse 24 at least a portion of the length of primary compartment 3 so that recess 14 of lock pin 4 aligns with a portion of latch 11. In an unlocked configuration, latch 11 can disengage interconnection between latch tooth 18 and strap tooth 10 of ratchet strap 9.

(26) In an alternate embodiment, it is within the scope of this invention for lock pin 4 to be retained within primary compartment 3 of lock housing 2 in its entirety or in part. For example, lock pin 4 does not have to protrude from lock housing 2 when recess 14 of lock pin 4 is aligned with a portion of latch 11. Lock housing 2 could extend the entire length of lock pin 4.

(27) FIGS. 2 and 3 both show lock pin 4 having recess 14. The perimeter of lock pin 4 is smaller in size at recess 14. FIG. 2 illustrates lock mechanism 20 of lock housing 2 positioned in a locked orientation in which the lock is engaged. A portion of lock jam ball 15 is retained within recess 14 of lock pin 4 when the lock mechanism 1 is locked. Latch 11 cannot be depressed because lock pin 4 obstructs movement of latch 11.

(28) FIGS. 1A and 2 best show lock mechanism 20 of a releasable ratchet strap having a lock mechanism 1 being in a locked orientation. Latch tooth 18 of lever 11 interlocks with at least one strap tooth 10 of ratchet strap 9. Latch 11 cannot pivot due to lock pin 4 obstructing latch 11 from pivoting.

(29) FIGS. 1B and 3 best illustrate lock mechanism 20 of a releasable ratchet strap being positioned in an unlocked orientation. Latch tooth 18 of lever 11 is disengaged from strap tooth 10 of ratchet strap 9 when recess 14 of lock pin 4 is aligned with a portion of latch 11.

(30) FIG. 3 illustrates lock mechanism 20 of lock housing 2 positioned in an unlocked configuration. For example, when key 16 is turned by an authorized user (not shown), lock cam 17 orients to receive a portion of lock jam ball 15. Resilient member 7 pushes lock pin 4. Recess 14 of lock pin 4 is aligned with a portion of latch 11.

(31) FIGS. 4 and 5 illustrate an alternate embodiment of releasable ratchet strap having a lock mechanism 1. It is within the scope of this current invention for ratchet strap 28 (FIG. 5) to have a plurality of strap teeth 27 having an outer wall surface having a perimeter tapering from a larger perimeter to a smaller perimeter. It is within the scope of this invention for the ratchet strap to have a plurality of ridges on at least one side of the ratchet strap. It is within the scope of this invention for the ratchet strap to have a plurality of ridges around the perimeter of the ratchet strap. Ratchet strap 28 is made of a plurality of strap tooth segments 27.

(32) Ratchet strap 28 can have robust flexible inner core 25. Flexible inner core 25 has proximal end 36A located opposite distal end 36B. Proximal end 36A of flexible inner core 25 is connected to primary anchor structure 26A. Distal end 36B of flexible inner core 25 is connected to secondary anchor structure 26B. FIG. 7 illustrates secondary anchor structure 26B is configured to be retained in anchor structure compartment 32 of a strap tooth segment 27.

(33) FIGS. 6-12 illustrate strap tooth segment 27 having an outer wall surface having a perimeter tapering from a larger perimeter to a smaller perimeter. FIGS. 6-7 and 9-12 illustrate strap tooth segment 27 having an end having a convex protrusion 29. Convex protrusion has secondary opening 35B.

(34) FIGS. 7-9 show strap tooth segment 27 having central bore 31 (FIGS. 7-9 and 12) having primary opening 35A located opposite secondary opening 35B. Strap tooth segment 27 has concave recess 30 retaining the convex protrusion of a second strap tooth segment (not shown). Anchor structure compartment 32 retains an anchor structure (not shown). Strap tooth segment 27 has robust flexible inner core compartment 33 retaining a portion of flexible inner core 25 (FIG. 5).

(35) FIG. 5 shows a preferred embodiment of ratchet strap 28 having secondary anchor structure 26B located in the most distal strap tooth segment of the ratchet strap 28. Secondary anchor structure 26B retains the plurality of segments 27 of strap teeth onto flexible inner core 25.

(36) FIGS. 10 and 12 illustrate strap tooth segment 27 having concave recess 30, anchor structure compartment 32, and robust flexible inner core compartment 33(FIG. 10-12).

(37) It will thus be seen that the objects set forth above, and those made apparent from the foregoing description, are efficiently attained. Since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matters contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

(38) It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention that, as a matter of language, might be said to fall therebetween.
