6 Description of the Related Art 7 It is widely known that there are millions of dog owners in 8 this country as well as other countries throughout the world. Dogs 9 comprise one of the most popular types of animals for household pets. Of course, dogs are extremely popular animals for other than 11 simple companionship. Other uses of dogs include working dogs and 12 show dogs. In turn, working dogs may be classified as dogs 13 utilized for police enforcement purposes, military activities, dogs 14 trained for hunting and also dogs specifically trained to aid those individuals who are visually impaired.

16 Regardless of the above classifications, the care and 17 maintenance of dogs require the use of numerous auxiliary or 18 supplementary items. Among the most popular is the dog leash or 19 tethering assembly wherein dogs are retained and/or restricted for purposes of control when not contained by fences in a yard or like 21 area. Moreover, similar type leash assemblies are also useful on a 22 variety of different animals including pets and farm animals, such 23 as horses.

24 It is also well recognized that leash structures, collars, harnesses, etc., are available in numerous and varying designs C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\1030C-CIP PATENT
APPLICATION FILED.DOC

1 intended to control an animal for different purposes. Prior art 2 structures exist which comprise leash and collar combinations 3 specifically structured such that the length of a lead of the leash 4 assembly is selectively variable so that the dog or animal being tethered may enjoy a greater range of movement and freedom when the 6 surrounding area allows. Alternately, the tethered animal may be 7 restrained, by shortening the length of the extendable lead in 8 areas which do not allow the free roaming of the dog. Other prior 9 art leash or tethering assemblies are specifically designed to allow control and retention of the dog or other animal while 11 significantly reducing or eliminating the tangling of the dog in 12 the retaining harness and/or about an anchoring structure to which 13 the animal is tethered.

14 An area which is not currently addressed by leash and retaining harness assemblies is the ability to quickly and easily 16 connect an animal to the leash assembly and to permit release of 17 the animal from a spaced distance from the animal, such as a remote 18 location. In the majority of conventional or known leash 19 assemblies, it is necessary for a handler to manipulate a coupling structure utilizing both hands, wherein the coupling structure 21 serves to connect the distal end of the lead to the collar or 22 retaining harness mounted on taze animal. This generally involves 23 direct handling or manipulation of any one of a large variety of 24 such coupling structures. Attachment of the animal can be extremely difficult, particularly when the dog or animal being C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\1030C-CIP PATENT
APPLICATION FILED.DOC

1 tethered is overly frisky or otherwise in an excited state. Also, 2 in accomplishing either attachment or detachment of the lead from 3 the collar or like harness particular problems are encountered by 4 the elderly or by those who are visually or otherwise physically challenged.

6 In addition to the above, the handling of larger animals, such 7 as horses and/or working dogs of the type trained to conduct police 8 enforcement and/or military activities, requires that the animal be 9 kept under control by the handler. However, in cases of emergency, it is equally important that the animal be released or detached 11 from his controlling lead as quickly as possible as it could be 12 dangerous for the animal to begin running while dragging the lead 13 or any part of the leash assembly. Conversely, if the animal is 14 loose, it may be necessary to quickly re-harness the animal in order to restrain its movement in a hazardous situation.

16 A further problem is encountered in the handling, and in 17 particular, the transportation, of horses. Specifically, when a 18 horse is being confined in a trailer they often become anxious 19 and/or excited. Combined with the tight space limitations of most trailers, the excited condition of the animal presents a dangerous 21 situation for the handler who must enter the trailer to either 22 attach or release the animal from the trailer,,, Thus, it would be 23 advantageous and potentially life saving for both the animal and 24 the handler to provide a means to remotely release a horse that is attached to a trailer. At a minimum, it would be advantageous to C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\1030C-CIP PATENT
APPLICATION FILED.DOC

1 provide a remote, emergency release activation mechanism on an 2 exterior portion of the trailer, such that the animal could be 3 released without requiring the handler to enter the trailer, which 4 may cause the animal to become even more anxious or excited.

Another area which the prior or related art does not address 6 is related to facilitating adjustment of the length of the lead by 7 the handler utilizing a retractable leash assembly. In particular, 8 although the prior art devices allow the length of the lead, and 9 thus, the distance between the animal and the handler, or a fixed tethering location, to be adjusted, they do not provide a means to 11 align the lead for smooth and easy retraction or release of the 12 lead regardless of the relative position of the animal to the 13 handler or the tethering location. More specifically, when the 14 lead is extended a long distance, the angle formed between the lead to the handler is quite different than the angle formed when the 16 animal is in close proximity. Thus, the handler is forced to 17 constantly adjust the position of the device relative to the animal 18 to prevent binding of the lead with the housing of the device 19 during retraction or release of the lead to or from the handle, respectively. Additionally, movement of the animal to the left or 21 right of the handler or tethering location may also increase the 22 potential fox- binding of the lead upon retraction or release ofy the.
23 lead into or from the housing of the assembly. Nor does the prior 24 leash and/or tethering assembly art provide a means to lock the lead in position relative to the assembly upon detection of a C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\1030C-CIP PATENT
APPLICATION FILED.DOC

1 specific release velocity or sudden acceleration of the lead from 2 the housing, as may occur when an animal becomes excited or angry 3 and bolts from the handler or the tethering location.

4 Accordingly, there is a recognized need in this area for a leash or tethering assembly including a quick connect coupling 6 assembly having coupling components structured to easily align into 7 position for connection by a handler with a single hand. It would 8 also be preferable for such an assembly to allow connection and 9 release from an animal by the handler while in an upright position, thereby eliminating the need for the handler to bend over, such as 11 may be inconvenient for elderly or infirm handlers. Further, such 12 a preferred leash or tethering assembly should be structured to 13 permit quick and effective detachment or release of the animal via 14 an activation assembly located a spaced distance from the animal and the coupling component serving to connect the animal harness to 16 the lead. Preferably, such an activation assembly may utilize 17 mechanical, electrical, and/or magnetic forces to facilitate the 18 alignment and interconnection of the coupling components. Further, 19 it would be beneficial for the activation assembly to utilize mechanical, electrical, magnetic, electromagnetic, fiber optic, 21 computer generated, and/or remote voice activated signals to effect 22 the release of the coupling ,_,omponents of the leash assembly from 23 one another.

24 It would further be beneficial to provide a leash assembly including wherein the activation assembly includes a lead aligning C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\1030C-CIP PATENT
APPLICATION FILED.DOC

1 mechanism structured to maintain the lead in position relative to 2 the housing of the activation assembly as the lead is retracted 3 and/or released into or from the housing, respectively, to minimize 4 binding of the lead with the housing. Yet another desirable feature for such a leash assembly is a release control mechanism to 6 prevent unwanted release of a lead upon sudden acceleration of the 7 animal away from the handler or tethering location, as may occur 8 when an animal becomes excited or angry.

9 Another disadvantage of the retractable leash assemblies of the type commercially available is that they are typically spring 11 biased to the extent that a release mechanism allows a free 12 extension of the lead as the tethered animal travels a greater 13 distance from the handler. As such, in these known devices, the 14 lead cannot normally be retracted or rewound without the handler first providing slack in the lead by following or chasing the 16 animal and thereby shortening the distance between the handler and 17 the animal prior to rewinding the lead for storage. Therefore, it 18 would also be desirable to provide a leash or tethering assembly 19 having a drive mechanism, to facilitate the retrieval of an animal attached to the leash assembly to the proximity of the handler or 21 tethering location without requiring the handler to traverse the _-22G., distance between themselves and the animal.

23 Further, while the foregoing discussion is directed to the 24 leash and tethering assembly art, it is envisioned that such a quick connect coupling assembly as described herein will have C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY" INTERNET
FILES\OLK5\1030C-CIP PATENT
APPLICATION FILED.DOC

1 numerous other practical applications including, but not limited 2 to, tie downs for tools and equipment, securing luggage and/or 3 sporting equipment, temporary barrier devices, body harnesses, and 4 key chains, as well as in the area of robotics, including integration into automated factory assembly line operations, and 6 remotely controlled devices utilized by military, law enforcement, 7 emergency, and rescue personnel, just to name a few.

9 Summary of the Invention The present invention relates to a leash assembly designed to 11 allow control of a dog or other animal by a handler and which is 12 structured to accomplish a quick detachment of the animal from a 13 remote position without requiring the direct handling or 14 manipulation of the quick connect coupling assembly serving to interconnect the collar, harness, or similar attachment assembly to 16 the distal end of the lead. The present invention is also designed 17 and structured to provide a quick and efficient attachment of a 18 lead to an attachment assembly utilizing only a single hand of the 19 user or handler. More specifically, the present invention comprises a flexible material lead being of any appropriate or 21 preferred length and terminating at a distal end and an oppositely 22 disposed pLoximal end. A preferably rotating coupling componentli_s 23 connected, at least in part, to the distal end of the lead and is 24 specifically structured to accomplish a quick and easy attachment of the lead to the attachment assembly, as well as a quick release C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\1030C-CIP PATENT
APPLICATION FILED.DOC

1 or detachment of the lead from an attachment assembly mounted 2 directly on the animal being tethered.

3 In order to accomplish such quick release of the coupling 4 assembly, the present invention further comprises a release structure preferably in the form of a release or positioning cable 6 formed of metallic or other applicable material having sufficient 7 structural integrity to be movable axially along its own length and 8 to exert an axially directed force on a coupling assembly to be 9 described in greater detail hereinafter. The term "structural integrity" refers to the structural features of the release cable 11 being of a material with sufficient rigidity, while still being 12 flexible, to exert the aforementioned axially directed force on the 13 coupling assembly or otherwise structured to be axially moveable 14 along the length of the lead so as to exert the aforementioned force on the coupling assembly and thereby orient the coupling 16 assembly in a disconnect position, as will be explained in greater 17 detail hereinafter.

18 The release structure or cable is mounted on and preferably 19 within the interior of the lead and extends along the length thereof between the aforementioned distal end and proximal end.
21 One end of the release cable is disposed adjacent the distal end of 22 the lead and is connecte~-!- directly to the preferably rotating 23 coupling component. Selective axial movement of the release cable 24 causes a disconnection of the coupling components defining the subject coupling assembly. The aforementioned quick release is C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\1030C-CIP PATENT
APPLICATION FILED.DOC

1 thereby accomplished from a location remote from the animal without 2 the necessity of directly handling or manipulating the coupling 3 assembly. Alternate embodiments of the present invention include a 4 coupling assembly comprising magnetically attractive components, and a release structure comprising an electromagnet whose polarity 6 may be reversed to alternately facilitate automatic attachment and 7 detachment of the components.

8 To accomplish the desired quick release, the present invention 9 also includes an activation assembly mounted adjacent the proximal end of the lead and includes an activation member connected 11 directly to the correspondingly positioned end of the release 12 cable. Depending upon the various embodiments, to be described in 13 greater detail hereinafter, the activation member may be disposed 14 and configured for direct manipulation by a thumb or finger of a single hand of a person gripping a handle portion of the activation 16 assembly which is connected to the proximal end of the lead. By 17 depressing or otherwise manipulating the activation member, the 18 release cable is forced to move axially along its length relative 19 to the lead on which it is mounted. This movement will cause an axially directed force to be exerted directly on at least one of 21 the coupling components of the coupling assembly and a 2 2 disconnection of the coupling assembly. A qvick release and/or 23 detachment of the attachment assembly will thereby be effected.
24 Additional embodiments of the present invention include an electronically operated activation assembly, which may or may not C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\1030C-CIP PATENT
APPLICATION FILED.DOC

1 be radio activated.

2 Another feature of one preferred embodiment of the leash 3 assembly of the present invention further includes an activation 4 assembly comprising a drive motor to be actuated by a user. The drive motor is configured, such as by attachment to a storage or 6 take-up spool, to effectuate storage of the lead itself and/or 7 activation of the quick release structure.

8 An additional embodiment of the present invention includes the 9 coupling assembly structured to provide a quick attachment and detachment of the distal, free end of the lead to the attachment 11 assembly mounted on the animal. In addition, a similarly 12 structured coupling assembly may be used to connect opposite free 13 ends of the attachment assembly to one another around the animal in 14 an intended fashion. In the aforementioned coupling assembly, first and second components are structured so as to be attached to 16 one another in a manner which only requires a single hand of the 17 handler or user of the leash assembly of the present invention.
18 Quick and easy release of the two components of the coupling 19 assembly from one another is accomplished by manipulation of the activation assembly and movement of the release structure mounted 21 within the lead, as set forth above. More specifically, each of 22 the compGxlen:t.s of the present invention may be positioned__ini.o a 23 predetermined aligned engagement with one another such that a 24 pushing force exerted on the first and second components of the coupling assembly will cause a quick and efficient attachment of C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\I030C-CIP PATENT
APPLICATION FILED.DOC

1 the two components to one another. Such quick attachment can be 2 accomplished without manipulation of a spring biased plunger 3 normally associated with generally known, swivel type coupling 4 assemblies. Further, the coupling assembly may include an alignment assembly structured and disposed to facilitate the 6 aforementioned predetermined aligned engagement of the components 7 with one another. The alignment assembly preferably comprises 8 magnetic surfaces on each component of the coupling assembly 9 cooperatively disposed in engageable relation with one another when the components are aligned.

11 It is an object of the present invention to provide a leash 12 assembly which is strong and secure, yet which also provides for 13 the quick and easy release of the animal restrained thereby.

14 A further object of the present invention is to provide a leash assembly which is substantially easy to operate and does not 16 require direct user manipulation of a coupling assembly when 17 connecting the attachment assembly on the animal to a lead 18 associated with the leash assembly.

19 It is also an important object of the present invention to provide a leash assembly structured to facilitate rapid and 21 efficient connection of an attachment assembly, mounted on the 22 animal, to a lead in a maZn.e~- which requires minimal manipulation 23 and the use of only one hand of the animal handler.

24 Yet another object to the present invention is to provide a leash assembly including a lead which may be retracted or extended C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLKS\1030C-CIP PATENT
APPLICATION FILED.DOC

1 in a controlled manner whether or not the free end of the lead is 2 secured to the attachment assembly. It is also an important object 3 to the present invention to provide the leash assembly, including 4 the various operative components associated therewith, which is formed from a light weight yet durable material so as to be 6 operable over an extended period and which is structurally designed 7 to be produced or manufactured relatively inexpensively so as to 8 make the present invention available to a wide range of potential 9 customers.

It is a further object of this invention to provide a quick 11 connect coupling assembly which may be utilized in a variety of 12 other connection applications. The need for a coupling assembly 13 permitting quick release and/or attachment exists in many 14 applications, for example, tie downs for equipment, tools, or machinery, securing luggage and/or sporting equipment, temporary 16 barrier devices, body harnesses, and key chains. Thus, the present 17 invention provides such a quick connect coupling assembly for the 18 aforementioned applications, however, the present invention may be 19 utilized in numerous other connection applications as may easily be envisioned.

21 These and other objects, features and advantages of the -~.22 present invention will become more clear wherl the drawings as well 23 as the detailed description are taken into consideration.

23 A loop type connector 32 may also serve to movably mount the 24 second component 22 of the coupling assembly 16 to the attachment assembly 26 such that the entire coupling assembly 16 is allowed to C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 move freely along the length of the attachment assembly 26 in order 2 to provide the animal more freedom when connected to the lead 10 3 and also to reduce the possibility of tangling of the attachment 4 assembly 26 with the remainder of the lead 10.

With regard to Figure 3, an alternate embodiment is disclosed 6 wherein the second component indicated as 22" is fixedly mounted on 7 an exterior surface of the attachment assembly 26. The structural 8 features of the second component 22" are similar to that of the 9 second component 22 of Figure 1 in that it is designed to removably receive the first component 18 therein.

11 With reference to the embodiment of Figures 1 and 2, the 12 release structure which comprises release cable 24 in a preferred 13 embodiment, is preferably mounted within an interior 25 of an outer 14 flexible material, such as lead 10, as illustrated in Figure 2. The lead 10 may therefore assume a generally tubular configuration so 16 as to enclose the release cable 24 in a hollow interior 25 thereof.
17 Alternatively, as illustrated in Figure 2A, a separate hollow 18 sheath structure 27 may be provided and preferably secured to or 19 embedded or concealed within the lead 10'. The sheath structure includes a hollow interior 25' and preferably extends along the 21 entire length of the lead 10' so as to enclose the release cable 24 22 therein along substantially its entire length. Such a 23 configuration is particularly beneficial in woven material lead 24 structures, or if the lead structure is to be wound, because movement of the release cable 24 while in an at least partially C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 wound position is required. In the embodiment illustrated in 2 Figure 2A, the sheath structure 27 is configured to facilitate the 3 sliding movement of the release cable 24 relative to the lead 10'.
4 As set forth above, the coupling assemblies 16 and/or 28 may be similarly structured and, as also set forth above, additional, 6 more preferred embodiments of the coupling assemblies similar to 16 7 and 28 are shown in detail in Figures 6-8. With reference to 8 Figure 5, the coupling assembly 16' may incorporate structural 9 features similar to those shown in Figures 6-8, in which the coupling assembly is referenced by either 16' or 16". With further 11 reference to Figure 4, coupling 16 may include a spring biased 12 plunger 51, which when axially disposed inwardly towards an 13 interior portion 53 of the second component 22 will serve to 14 release the one or, preferably, two outwardly extending, oppositely disposed locking members 62 from their normally biased outwardly 16 extending locking orientation. In a preferred embodiment of the 17 present invention, the locking members 62 will comprise an 18 elongated finger configuration as illustrated in Figures 6-8.
19 However, it is anticipated that the present invention may encompass other configurations of locking members 62, including but not 21 limited too, ball bearings, wedge shaped, cone shaped, etc.
22 Re1ease of the locking members 62 from their normally biased 23 outwardly extending locking orientation will allow attachment of 24 the first coupling component 18 to the second coupling component 22.

1 For purposes of clarity the structural details of the 2 preferred embodiments of Figure 6-8, are explained with reference 3 to coupling assemblies 16' and 16" as indicated in the 4 aforementioned Figures. It is again to be emphasized that the structural components of the coupling assemblies 16' and 16" may be 6 similar. One similarity between the different embodiments of 7 Figure 6-8 is the ability to accomplish a quick and efficient 8 attachment and release of the components of the respective coupling 9 assemblies 16' and 16", such as while utilizing only a single hand of the user. Further, attachment can be accomplished without the 11 physical depression or other manipulation of the spring biased 12 plunger 51 or any similar component.

13 More specifically, a feature of the embodiment of the coupling 14 assembly 16' of Figure 6 as well as the additional preferred embodiment 16" of Figures 7 and 8 is the inclusion of one or, 16 preferably, two locking members 62 having an outer surface 17 specifically configured to facilitate the quick and efficient 18 attachment or release of the first component 18' to or from the 19 second component 22'. In particular, each of the locking members 62 includes a leading surface portion 65 and a trailing surface 21 portion 67. The locking members 62, as shown in Figure 6, are 22 disposed in their ncrmally biased outwardly extending locking 23 orientation between the first component 18' and the second 24 component 22'. Furthermore, the trailing surface portions 67 of each of the locking members 62 are configured into a transverse, C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

APPLICATION FILED.DOC

1 linear shape so as define a stop member which will prevent unwanted 2 detachment of the first and second components 18' and 22' from one 3 another such as when they are pulled away from one another by the 4 strain of the animal or other forces. As such, it is necessary to affirmatively dispose the locking members 62 inwardly into the 6 interior of the first component 18' in order to define a retracted 7 orientation and allow passage of the leading end 64 of component 8 18' through the receiving aperture as at 69 formed in the second 9 component 22'.

Looking in greater detail, the coupling assembly 16' comprises 11 a first component 18' and a second component 22' which, as shown, 12 are respectively configured to define a male coupling component and 13 a female coupling component. At least one, preferably the male 14 coupling component, is preferably structured to rotate or swivel, thereby allowing the entire coupling assembly 16' to be rotatable 16 and swivelable to prevent tangling and the like. As explained 17 above, the first component 18' may be connected to the distal or 18 free end of the lead 10 and, more specifically, in direct operative 19 attachment to the release structure, which in one preferred embodiment comprises an interior, axially moveable release cable 21 24. The release cable 24 may be connected directly to a plunger 60 22 so as to exert an axially directed fol ce thereon which in turn 23 permits the easy release of the first component 18' from the second 24 component 22' by virtue of the fact that an axially directed pulling force will cause the plunger 60 to move outwardly against a C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 force exerted thereon by a biasing spring (not shown) This 2 outward movement of the plunger 60 will in turn cause the locking 3 members 62 to be released from their normally biased outwardly 4 extending locking orientation and pulled into a retracted orientation, thereby allowing the first component 18' to be easily 6 released from the second component 22'.

7 In an alternate embodiment of the coupling assembly 16", as 8 illustrated in Figures 7 and 8, the locking members 62' and the 9 second component 22' may comprise oppositely charged magnetic materials, such that the attractive and/or repulsive magnetic 11 forces are sufficient to maintain the locking members 62' in their 12 normally biased outwardly extending locking orientation. In this 13 embodiment, the plunger 60 is connected to each locking member 62', 14 wherein an outward axial force is required to reposition the locking members 62' from their normally biased outwardly extending 16 locking orientation to the retracted orientation, so as to allow 17 the first component 18' to be easily released from the second 18 component 22'.

19 In yet another embodiment of the coupling assembly 16", the locking members 62' may in whole or in part comprise a magnetically 21 charged material. Additionally, the release structure comprises an 22 elect.x;omagnet which replaces the release cable 24 ard _plunger 60 23 and generates a stronger, similarly polarized magnetic field 24 relative to the locking members 62' such that the repulsive magnetic forces are sufficient to force the locking members 62' C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

APPLICATION FILED.DOC

1 into their normally biased outwardly extending locking orientation.
2 To release the first component 18' from the second component 22' in 3 this embodiment of the present invention, an electrical current may 4 be applied to the electromagnet which reverses its polarity, thus causing the locking members 62' to be pulled into a retracted 6 orientation by magnetic attraction which permits the first 7 component 18' to be automatically detached from the second 8 component 22'. In such an embodiment, an independent biasing force 9 on the locking members 62 may not be necessary.

A further embodiment of the present invention incorporates an 11 electromotive release mechanism 160 comprising an actuation member 12 162 and being disposed in an operative association with at least 13 one, but preferably a plurality of locking members 62', as shown in 14 Figures 25A through 28B. In particular, the operative association is at least partially defined by the electromotive release 16 mechanism 160 being structured to normally dispose the locking 17 members 62' into an outwardly extending locking orientation. The 18 operative association is further defined by the electromotive 19 release mechanism 160 being further structured to selectively dispose the locking members 62' into the retracted orientation, 21 upon actuation of the electromotive release mechanism 160, such 22 that a first component.1_8' and a corresponding second component 22' 23 of the coupling assembly 16' are detached from one another.

24 More specifically, in at least one preferred embodiment, the actuation member 162 of the electromotive release mechanism 160 C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

APPLICATION FILED.DOC

1 comprises a distal portion 163 structured to normally dispose the 2 locking members 62' in the outwardly extending locking orientation, 3 such as, for example, via displacement of the locking members 62', 4 as illustrated in Figures 25A, 26B, and 28A. Additionally, the distal portion 163 of the actuation member 162 is structured to 6 selectively dispose the locking members 62' into a retracted 7 orientation, thereby permitting the first component 18' and the 8 second component 22' of the coupling assembly 16' to be detached 9 from one another. The distal portion 163 of the actuation member 162 is movably disposable between an extended displacement 11 configuration such that the locking members 62' are disposed in the 12 outwardly extending locking orientation, as illustrated in Figures 13 25A and 28A, and a retracted non-displacement configuration such 14 that the locking members 62' are disposed in the retracted orientation, as illustrated in Figures 25B and 28B. In at least 16 one alternate embodiment, the distal portion 163 may comprise a 17 magnetically charged material, such as, by way of example only, an 18 electromagnetic, so as to further facilitate positioning the 19 locking members 62' between the outwardly extending locking orientation and the retracted orientation.

21 In one further embodiment, the distal portion 163 is movably 22 disposable between a non-displacement configuration such that the 23 locking members 62' are disposed in the retracted orientation, as 24 illustrated in Figure 26A and a displacement configuration such that the locking members 62' are disposed in the outwardly C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 extending locking orientation, as illustrated in Figure 26B. In 2 this embodiment, the actuation member 162 is structured to rotate 3 about an actuation axis 162', as illustrated in Figure 26C, wherein 4 the required rotation may be accomplished by way of an electromotive release mechanism 160 comprising a rotary solenoid.
6 In yet one other embodiment, the electromotive release 7 mechanism 160 may comprise at least one interconnecting member 164 8 disposed between the actuation member 162 and each locking member 9 62'. As shown in Figures 27A and 27B, the electromotive release mechanism 160 may comprise a plurality of interconnecting members 11 164, such as a wire or a cable, wherein the interconnecting members 12 164 are structured to dispose the locking members 62' between the 13 outwardly extending locking orientation and the retracted 14 orientation upon repositioning of the actuation member 162, as illustrated. In at least one embodiment, the interconnecting 16 members 164 comprise a shape memory alloy component structured to 17 dispose the locking members 62' from the outwardly extending 18 locking orientation to the retracted orientation upon actuation of 19 the electromotive release mechanism 160. Specifically, actuation of the electromotive release mechanism 160 results in an electrical 21 current being at least temporarily applied to the shape memory 22 allov component, thereby altering its physical cony igA..:ration and 23 causing the locking members 62' to be reoriented.

24 The electromotive release mechanism 160 may comprise any one of a number of electrically actuated devices including, by way of C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\1030C-CIP PATENT
APPLICATION FILED.DOC

1 example only and in no manner limited to, solenoids, transformers, 2 electromagnets, capacitors, electric motors, shape memory alloy 3 components, magnetic propulsion devices, etc. Looking just at 4 solenoids, the electromotive release mechanism 160 may comprise a plunger type solenoid, a hammer type solenoid, a swing solenoid, a 6 rotary solenoid, a tubular type solenoid, etc., and these are only 7 a few of the possible types of solenoids illustrative of those 8 which may be comprised by the electromotive release mechanism 160 9 of the present invention. As such, it is understood that any electromotive device comprising an actuation member 162 which may 11 effect the disposition of the locking members 62' between the 12 outwardly extending locking orientation and the retracted 13 orientation upon application of an electrical current, may be 14 utilized and are encompassed in the scope of the present invention.
To facilitate actuation of the electromotive release mechanism 16 160, an actuation interface 166 is provided and is structured to 17 facilitate selective actuation of the electromotive release 18 mechanism 160, via selective application of an electrical current 19 to the electromotive release mechanism 160, as desired by the user.
The actuation interface 166 may comprise a direct interconnection 21 to the activation assembly 80 or 82 such as, for example, an 22 electrical wire extending along the lead 10 between the 23 rechargeable power supply 81' of the activation assembly 80 or 82 24 and the electromotive release mechanism 160. As such, a selective activation member 44', as described herein, may be utilized to C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

APPLICATION FILED.DOC

1 selectively actuate the electromotive release mechanism 160 via 2 selective application of an electrical current from the 3 rechargeable power supply 81'.

4 In at least one embodiment, the actuation interface 166 is disposed in a communicative relationship with a voice activated 6 control module 110, also as described herein, thereby allowing the 7 electromotive release mechanism 160 to be remotely actuated. One 8 further embodiment of the present invention comprises a manual 9 release mechanism 167 interconnected to the actuation interface 166, as illustrated in Figures 27A and 27B, the manual release 11 mechanism 167 structured to permit manual actuation of the 12 electromotive release mechanism 160, thereby allowing the first 13 component 18' and the second component 22' to be quickly and easily 14 detached from one another.

Also as indicated, a further feature of the present invention 16 is its ability to achieve easy and effective engagement or 17 attachment between the first component 18' and the second component 18 22'. This attachment is preferably facilitated by virtue of the 19 fact that the leading surface portion 65 of each of the locking members 62 has a substantially convergent configuration which 21 extends outwardly in either a curvilinear or sloped shape.
22 Accordingly, engagement of the leading surface portion 65 with the 23 periphery of the receiving aperture 69 will cause a sliding 24 engagement of the respective locking members 62 relative to the periphery of the receiving aperture 69 and thereby cause a forced, C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\1030C-CIP PATENT
APPLICATION FILED.DOC

1 inward retraction of the locking members 62 to counter their 2 normally biased outwardly extending locking orientation. The 3 leading end 64 of the first component 18' will thereby be allowed 4 to pass through the receiving aperture 69 into the engaged and attached position as shown in Figures 6 and 8 in a substantially 6 facilitated manner.

7 In order to accomplish such quick and easy attachment of the 8 components 18' and 22' together into the attached position of 9 Figures 6 and 8, the first and second components 18' and 22' should be disposed in predetermined aligned engagement with one another.
11 Such predetermined aligned engagement may be defined by an axial 12 alignment of the first component 18' with the second component 22' 13 as best shown in Figure 7. Once the first and second components 14 18' and 22' are in the aforementioned axial alignment, forced positioning of these two components 18' and 22' towards one another 16 as indicated by directional arrows 70 and 71 will cause sliding 17 contact of the leading surface portion 65 with the periphery of the 18 receiving aperture 69 resulting in the predetermined aligned 19 engagement of the first and second components 18' and 22'. The cooperatively structured configuration of the first and second 21 components 18' and 22' of the preferred embodiment of the coupling 22 ~ssembly 16' allows the predetermined aligned engagement and 23 attachment of the first and second components 18' and 22' by the 24 user with a single hand.

As set forth above in order to accomplish a quick and easy C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 attachment of the components 18' and 22' to one another in the 2 locked position of Figures 6 and 8, the first and second components 3 18' and 22' are disposed in axial alignment with one another. To 4 further assist the axial alignment of the first and second components 18' and 22', each of the embodiments of Figures 6 6 through 8 also preferably include an attraction assembly 75 which 7 facilitates the axial alignment and automatic attachment of the 8 components 18' and 22' to one another. Such an attraction assembly 9 75 is mounted on the coupling assembly 16' in the form of correspondingly positioned, attractive, mating or engaging 11 surfaces. In the embodiment of illustrated Figure 6, the 12 attraction assembly 75 includes at least the exposed annular 13 surface 72 of the first component 18' being formed of a magnetic 14 material and configured to attract a similar annular surface 74 of the second component 22', also formed of a magnetic material. In 16 the locking position of Figure 6, these magnetically attractive 17 surfaces 72 and 74 will normally be brought into confronting 18 engagement with one another. The provision of the magnetically 19 attractive surfaces 72 and 74 and their relative disposition to one another will facilitate the axial alignment of the components 18' 21 and 22' as well as the inwardly directed connecting force indicated 22 by directional d.r_rQws 70 and 71 such that the first and second 23 components 18' and 22' are automatically attached. In at least one 24 embodiment, the attraction assembly 75 utilizes magnetic propulsion to achieve automatic attachment of the first and second components C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 18' and 22' by including an array of magnetic surfaces 72 or 74 2 having alternating polarities, or an array of magnetic surfaces 72 3 or 74 having similar polarities but exhibiting progressively 4 stronger or weaker magnetic forces.

In the embodiment of Figure 6, the magnetically attractive 6 surfaces 72 and 74 are substantially externally located when the 7 first and second components 18' and 22' are separated from one 8 another. Conversely, the additional preferred embodiment of 9 Figures 7 and 8 includes the magnetically attractive surfaces 78 and 79 disposed substantially interiorly but in the respective 11 position of the first component 18' with the second component 22' 12 as shown in Figure 8.

13 In addition, the attraction assembly 75 of the embodiment of 14 Figure 8 may also include interior side surfaces as at 82' which are designed to at least partially engage and cause the direct 16 attraction of the locking members 62'. Accordingly, in the 17 embodiment of Figure 8 the locking members 62' are at least 18 partially formed of a magnetically attractive material so as to 19 facilitate the aforementioned predetermined aligned engagement of the first and second components 18' and 22' with one another.
21 Further, the magnetically attractive surfaces may be utilized to 22 cause the first and second components 18' and 22' to automatically 23 engage and attach to one another when disposed in the predetermined 24 aligned relationship.

1 engagement or attachment of the components of the coupling assembly 2 16', at least one embodiment of present invention comprises an 3 electromotive propulsion mechanism 170, as illustrated in Figures 4 28A and 28B, structured to at least temporarily impart a separation force between the first component 18' and the second component 22'.
6 More in particular, the electromotive propulsion mechanism 170 of 7 the present invention comprises at least one propulsion member 172, 8 however, in one preferred embodiment, the electromotive propulsion 9 mechanism 170 comprises a plurality of propulsion members 172 disposed in a spaced apart relation to one another, as illustrated 11 in Figures 28A and 28B. The propulsion members 172 preferably 12 comprise an elongated configuration, as illustrated, and are 13 disposed adjacent a propulsion interface 174 formed between 14 abutting portions of the first component 18' and the second component 22' of the coupling assembly 16', as best shown in Figure 16 28A.

17 The electromotive propulsion mechanism 170 of the present 18 invention is specifically structured to dispose the propulsion 19 members 172 between a secured configuration and a separated configuration. Specifically, the secured configuration is at least 21 partially defined by the propulsion members 172 being disposed in 22 -an-inwardly retracted position by the electromotive propulsion 23 mechanism 170, as illustrated in Figure 28A. Conversely, the 24 separated configuration is at least partially defined by the propulsion members 172 being disposed in an outwardly extended C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\I030C-CIP PATENT
APPLICATION FILED.DOC

1 position by the electromotive propulsion mechanism 170, as 2 illustrated in Figure 28B. The disposition of the propulsion 3 members 172 from the secured configuration to the separated 4 configuration results in a separation force between the first component 18' and the second component 22' of the coupling assembly 6 16' in a direction substantially normal to the propulsion interface 7 174, as indicated by directional arrows 176 in Figure 28B. The 8 separation force is sufficient to cause the first component 18' and 9 the second component 22' to detach from one another when each of the plurality of locking members 62' is disposed in the retracted 11 orientation.

12 Similar to the electromotive release mechanism 160 previously 13 described, the electromotive propulsion mechanism 170 of the 14 present invention may comprise any one of a number of electrically actuated devices including, by way of example only and in no manner 16 limited to, solenoids, transformers, electromagnets, capacitors, 17 electric motors, shape memory alloy components, magnetic propulsion 18 devices, etc. As before, it is understood that any electromotive 19 device which may effect the disposition of the propulsion members 172 between the secured configuration and the separated 21 configuration upon application of an electrical current may be 22 utilized and are-ericompassed in the scope of the present invention..

1 jamming of the locking members 62' in the interior of the second 2 component 22', at least one embodiment of the present invention 3 comprises a time sequence module. The time sequence module is 4 structured such that actuation of the electromotive release mechanism 160 effecting retraction of the locking members 62' must 6 occur a preselected period of time before the electromotive 7 propulsion mechanism 170 is permitted to operate to dispose the 8 propulsion members 172 into the separated configuration. The 9 preselected period of time is determined by the amount of time required for the locking members 62' to fully retract after 11 actuation of the electromotive release mechanism 160.

12 In at least one embodiment, the electromotive propulsion 13 mechanism 170 may comprise an attraction mechanism, such as, for 14 example, an electromagnet, structured to be actuated by the time sequence module upon disposition of each of the propulsion members 16 172 from the outwardly extended position into an at least partially 17 inwardly retracted position. Specifically, the disposition of each 18 of the propulsion members 172 into an at least partially inwardly 19 retracted position is indicative of the second component 22' being disposed in proximity to the first component 16' in predetermined 21 aligned engagement, and the attraction mechanism is thus structured 22 to facilitate quick and easy connection of the components of the 23 coupling assembly 16' by imparting an attraction force between the 24 components.

A further embodiment of the present invention is illustrated C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 in Figure 29 and includes an electromotive release mechanism 160 2 having an actuation member 162 comprising a propulsion member 172'.
3 In this embodiment, the electromotive release mechanism 160, more 4 specifically, the actuation member 162, is structured to dispose the propulsion member 172' between a secured configuration and a 6 separated configuration via disposition of a distal portion 163 of 7 the actuation member 162 between a displacement configuration and a 8 non-displacement configuration, respectively. As shown, the 9 propulsion member 172' is structured to extend through a portion of the first component 18' and to contact an inner portion of the 11 second component 22', thereby exerting a separation force in a 12 direction substantially normal to a propulsion interface 174', as 13 indicated by directional arrow 176'. The separation force is 14 sufficient to cause the first component 18' and the second component 22' to detach from one another when each of the plurality 16 of locking members 62' is disposed in the retracted orientation.
17 Figure 30 presents a perspective view of yet another 18 illustrative embodiment of a quick coupling assembly, generally as 19 shown at 216, in accordance with the present invention. As above, the quick connect coupling assembly 216 is structured to allow 21 quick connection and quick release, and includes a first component 22: 222 and a second component 218 which are cooperati<vely structured 23 to assume an attached orientation, such as is illustrated in Figure 24 31, and a detached orientation, as in Figure 30.

1 coupling assembly 216 of this embodiment may comprise any of a 2 variety of materials of construction, which will typically be 3 dictated by the load to be placed on the assembly 216 in a 4 particular application. For example, in a light duty application, such as securing a small pet or a simple key chain, the first 6 component 222 and the second component 218 may comprise plastic, 7 aluminum, or another lightweight material for ease of carrying on a 8 pet or by a person, while permitting secure attachment of the 9 components. Alternatively, for heavy duty applications, the first component 222 and second component 218 may be constructed of 11 hardened steel, stainless steel, or any one of a number of other 12 metals, metal alloys, or specialty materials to assure secure 13 attachment is maintained between the components for the specific 14 application.

The quick connect coupling assembly 216 of the present 16 invention may also be structured such that at least a portion is 17 movable relative to an object attached thereto, such as via an 18 attachment portion 229, so as to prevent or at least minimize 19 tangles in a line, rope, wire, etc., attaching the assembly 216 to the object. As illustrated in the figures, in at least one 21 embodiment, the first component 222 comprises a fixed portion 223 22 and a moveab le pnrtion 224, wherein the moveable portion 224 .-is _.
23 movably interconnected to the fixed portion 223. In one preferred 24 embodiment, the moveable portion 224 is rotatably attached to the fixed portion 223, for example, via a swivel member 225, and is C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

The quick connect coupling assembly 216 also comprises a 6 locking assembly 260 structured to retain the first component 222 7 and the second component 218 in an attached orientation, such as is 8 illustrated, by way of example only, in Figure 31. As further 9 illustrated throughout the figures, the locking assembly 260 comprising at least one locking element 261, however, in the 11 illustrative embodiments presented herein, the locking assembly 260 12 comprises a plurality of locking elements 261 being movably 13 interconnected to the first component 222 of the quick connect 14 coupling assembly 216. In one embodiment of the present invention, the locking elements 261 are structured and disposed in a sliding 16 interconnection with the first component 222, as illustrated in 17 Figures 31, 38, and 39, for example, in tracks or channels. More 18 specifically, the sliding interconnection is defined such that the 19 locking elements 261 are not physically attached to the first component 222, rather, they engage the first component 22 is such a 21 manner so as to be "free floating" along or within the tracks or 22 channels thereof. In another embodiment, as best shown in Figures 23 33A, 33B, and 34, the locking elements 261 are structured and 24 disposed in a pivoting interconnection with the first component 222, such as, for example, about connection member 226.

1 In at least one embodiment, the locking elements 261 of the 2 present invention preferably comprise a locking arm 269 having a 3 locking member 262 disposed at one end thereof. In accordance with 4 a preferred embodiment, the locking arms 269 comprise an elongated configuration having corresponding ones of the locking members 262 6 disposed at one end thereof. As will be appreciated from the 7 various embodiments illustrated in the figures, however, the degree 8 to which any particular locking arm 269 is elongated may vary 9 considerably depending upon the internal configuration of the first component 222, and the manner in which the locking element 261 is 11 disposed to engage the first component 222, such as, by way of 12 example only, a sliding engagement or a pivoting engagement.

13 As in previously disclosed embodiments of a quick connect 14 coupling assembly 216 in accordance with the present invention, the locking members 262 of the present embodiment are structured to be 16 normally disposed and maintained in an outwardly extending locking 17 orientation, as illustrated, by way of example, in Figures 31, 32, 18 33A, and 33B. In particular, the locking members 262 are 19 structured to be disposed in an abutting relation with at least an abutment portion 220 of the second component 218. In the 21 illustrative embodiment of Figure 35, the locking elements 262 are 2 2_!i- cooperatively structured with the abutment portion 220 of the 23 second component 218 to at least partially define a complimentary 24 locking interface 221 being disposed between the locking members 262 and the abutment portion 220 of the second component 218. As C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 further shown in Figure 35, when disposed in such an abutting 2 relation, the locking members 262 of the locking assembly 260 are 3 structured and disposed to prevent detachment of the second 4 component 218 from the first component 222.

More specifically, Figure 35 illustrates a complimentary 6 locking interface 221 further defined by an abutment portion 220 of 7 the second component 218 comprising a sloping surface extending 8 downwardly from the receiving aperture 219 towards the exterior of 9 the second component 218. Furthermore, the leading surface portions 265 of the locking members 262 of this illustrative 11 embodiment also comprise a downwardly sloping surface which 12 "compliments" the slope of the abutment portion 220, thereby 13 further defining the complimentary locking interface 221 and 14 serving to prevent the unintentional detachment of the first component 222 from the second component 218. In particular, in 16 this embodiment, the leading surface portions 265 of the locking 17 members 262 must be extended up and over the sloping abutment 18 portion 220 of the second component 218 before the locking members 19 262 may be disposed into an inwardly retracted release orientation, such as illustrated in Figure 34, thereby permitting detachment of 21 the first component 222 from the second component 218.

22 At least.,one embodiment of the quick connect coupling assGmbly 23 216 of the present invention comprises an attraction assembly 275 24 structured to facilitate disposition of the first component 222 and the second component 218 into a predetermined alignment with one C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

APPLICATION FILED.DOC

1 another. The attraction assembly 275 of the present invention 2 comprises at least one attraction element 276 mounted to a first 3 component 222, or a second component 218, or, as illustrated 4 herein, the attraction assembly 275 comprises an attraction element 276 mounted to each of a first component 222 and a second component 6 218.

7 The attraction assembly 275 in at least one embodiment 8 comprises a plurality of magnetic attraction elements 277, such as 9 are shown in Figure 33A. More in particular, and as in the illustrative embodiment of Figure 33A, at least one magnetic 11 attraction element 277 is mounted to each of the first component 12 222 and the second component 218. Furthermore, the magnetic 13 attraction elements 277 are structured and disposed to create an 14 attractive magnetic force to facilitate disposition of the first component 222 and the second component 218 into the predetermined 16 alignment with one another, as illustrated, by way of example only, 17 in Figure 30.

18 As is also illustrated in the figures, the magnetic attraction 19 elements 277 are structured and disposed in a "free floating"
configuration, that is to say, they are structured and disposed so 21 as to prevent any physical contact with one another. This "free 22 floating" feature provides several advantages over other magnetic 23 attachment devices. First, by preventing physical contact, 24 mechanical degradation of the magnets of the magnetic attraction elements 277 is essentially eliminated, thereby significantly C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET
FILES\OLK5\1030C-CIP PATENT
APPLICATION FILED.DOC

1 increasing the useful life of the magnets. In addition, the "free 2 floating" configuration facilitates detachment of the first 3 component 222 and the second component 218, by eliminating the 4 significant force required to separate magnetic elements which are physically contacting one another.

6 In at least one embodiment, the attractive magnetic force 7 between the magnetic attraction members 277 is selectively 8 adjustable. Specifically, in this embodiment, at least one of the 9 magnetic attraction members 277 comprises an adjustable mount 278 structured to be moveable such that a distance between the elements 11 277 is selectively adjustable. In at least one embodiment, the 12 adjustable mount 278 may comprise a threaded mount, as illustrated 13 in Figures 33A and 34, wherein the distance between the magnetic 14 attraction members 277 is adjusted by simply rotating the magnetic attraction element(s) 277 further in or out via the adjustable 16 mount 278.

17 In one further embodiment, at least one magnetic attraction 18 element 277 is removeably mounted to either the first component 222 19 or the second component 218 via an adjustable mount 278, such that a magnetic attraction member 277 exhibiting greater or lesser 21 magnetic force may be quickly and easily installed, thereby 21211. allowing a user to select the magnetic force toAne exhibited by the 23 attraction assembly 275 over a wide range of magnetic forces, such 24 as may be necessitated by the various coupling applications in which the present assembly may be utilized. Of course, it is C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

APPLICATION FILED.DOC

1 within the intent and scope of the present invention to adjust a 2 distance between the magnetic attraction members 277 other than via 3 a threaded mount, and in at least one embodiment, each of a 4 plurality of magnetic attraction members 277 may comprise an adjustable mount 278.

6 The quick connect coupling assembly 216 of the present 7 invention may also comprise a shielding mechanism 290 having at 8 least one shielding element 292 which is structured to direct the 9 attractive magnetic force between the magnetic attractive elements 277. The shielding element 292 is further structured to prevent 11 the attractive magnetic force from attracting an unintended object.
12 The shielding mechanism 290 of the present invention may comprise a 13 flux-entrapment shield, or a lossy shield, which are basic types of 14 60 Hz shields.

A flux-entrapment shield is typically constructed of a 16 ferromagnetic, highly permeable nickel-iron alloy. In at least one 17 embodiment, the shielding element 292 may comprise an alloy which 18 is approximately 80% nickel and 20% iron, such as, Hipernom Alloy, 19 CO-NETIC AA, Aumetal, AD-MU-80, etc. Further, the shielding element 292 may be structured to isolate an area from a magnetic 21 source by either surrounding the area, such as a cylinder or 22 rectangular box, or separating the area from the magnetic source, 23 such as via a"U"-shaped or flat plate. In operation, the magnetic 24 flux generated by a magnetic source preferentially enters and travels through the highly permeable material along a path of least C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

APPLICATION FILED.DOC

1 magnetic reluctance, rather than passing through the highly 2 permeable material to the area isolated by such a shielding element 3 292.

4 Alternatively, the shielding mechanism 290 of the present invention may employ a lossy magnetic shielding system which 6 utilizes the eddy current losses occurring within highly conductive 7 materials including, but not limited to, copper, aluminum, iron, 8 steel, silicon-iron, etc. More in particular, when a highly 9 conductive material is subject to a time varying, e.g., 60 Hz, magnetic field, magnetic currents are induced within the material 11 which flow in closed circular paths, perpendicular to the inducing 12 magnetic field. According to Lenz's Law, these eddy currents 13 oppose the charges in the inducing field such that the magnetic 14 fields produced by the circulating eddy currents act to cancel the larger, external inducing magnetic fields at or near the conductive 16 surface of the shielding material, thereby imparting a shielding 17 effect.

18 The figures illustrative of the present embodiment of a quick 19 release coupling assembly 216 also show a biasing mechanism 270 comprising at least one biasing element 272 structured to normally 21 dispose and maintain the locking members 262 of the locking 22 assembly 260 in the outwardiy extending locking orientation. As 23 best illustrated in Figures 31 and 33A, in at least one embodiment, 24 the biasing mechanism 270 comprises a magnetic biasing element 273 mounted to each of oppositely disposed ones of the plurality of C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 locking elements 261. As further illustrated in the figures, the 2 magnetic biasing elements 273 are structured and disposed so as to 3 create a repulsive magnetic force between one another, as 4 demonstrated by the double headed arrows in the referenced figures.
In at least one embodiment, the magnetic biasing elements 273 are 6 structured such that the repulsive magnetic force generated between 7 the magnetic biasing elements 273 serves to maintain the locking 8 members 262 disposed on corresponding ones of the locking elements 9 261 in the normally disposed outwardly extending orientation, by forcing the locking elements 261 away from one another in opposite 11 directions, once again, as shown by the double headed arrows in 12 Figures 31 and 33A.

13 In one further embodiment, the biasing mechanism 270 is 14 structured such that a repulsive magnetic force between the magnetic biasing elements 273 is selectively adjustable. More in 16 particular, at least one of the magnetic biasing elements 273 17 comprises an adjustable base structured to be moveable such that a 18 distance between the magnetic biasing elements 273 mounted to 19 oppositely disposed ones of the locking elements 261 is selectively adjustable, thereby affecting the magnitude of the repulsive force 21 exerted by each magnetic biasing element 273 towards one another.

.,-.22 In yet one other embodiment of the quick connect coupling 23 assembly 216 of the present invention, the biasing mechanism 270 24 comprises a spring 274 mounted between oppositely disposed ones of the plurality of locking elements 261 wherein the spring 274 is C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

APPLICATION FILED.DOC

1 structured to maintain corresponding ones of the locking members 2 262 in the normally disposed outwardly extending orientation, once 3 again, by forcing the locking elements 261 into opposite directions 4 from one another. The spring 274 may be selected to provide greater or lesser amounts of force when disposed into an operative 6 position, such as illustrated in Figure 33B, such that, once again, 7 the force generated by the biasing mechanism 270 may be selectively 8 adjusted.

9 The quick connect coupling assembly 216 of the present invention also comprises a release mechanism 280 structured to 11 permit the locking members 262 to be temporarily disposed into an 12 inwardly retracted release orientation. More in particular, the 13 release mechanism 280 comprises at least one release member 282 14 mounted to one of a plurality of locking elements 261, wherein the release member 282 is structured to be normally disposed in an 16 outwardly extending orientation while the locking assembly 260 is 17 disposed in a locking orientation, as is illustrated throughout the 18 figures. Further, the release member 282 is disposable into a 19 release orientation thereby temporarily disposing one or more locking member 262 into an inwardly retracted release orientation, 21 as illustrated by way of example only in Figure 34, such that the 22 first component 222 and the second component 218 may be Aet'ached 23 from one another. As further illustrated in Figure 34, the release 24 assembly 280 may comprise a plurality of release members 282 each mounted to a different one of a plurality of release elements 261 C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 such that while a release force 283 is applied in the direction of 2 the arrows, such as by squeezing by a user, each of a corresponding 3 plurality of locking members 262 is temporarily disposed into the 4 inwardly retracted release orientation To prevent unintentional disposition of one or more release 6 member 282 into the release orientation, at least one embodiment of 7 the present invention comprises a safety mechanism 284 structured 8 to impede the application of a release force 283 to the release 9 member 282. More in particular, the release mechanism 284 is structured and normally disposed in a safety on configuration 11 which, in at least one embodiment, comprises a substantially 12 overlying relation to the release member 282, as illustrated best 13 in Figures 36 and 37. When desired by a user, the safety mechanism 14 284 is structured and disposable into a safety off configuration substantially exposing the release member(s) 282, as illustrated in 16 Figures 36A and 37A, thereby permitting disposition of the release 17 member(s) 282 into the release orientation.

18 To facilitate disposition between the safety on and safety off 19 configurations, at least one embodiment of the present invention comprises a moveable safety member 285. More specifically, the 21 moveable safety member 285 may comprise a slidable safety member 22 286 attached to the exterior of the first component 222 which is 23 structured to be normally disposed in the overlying relation with 24 the release mechanism 280, as in Figure 36. When desired, the slidable safety member 286 may be repositioned in the direction of C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

13 microchip is embedded in the first component 218, the first 14 component 218 being structured to remain attached to an animal via a collar or harness, so as to protect it from the elements, as well 16 as to conceal its presence as may be desirable in some cases. More 17 importantly, the GPS microchip 280 is structured to permit the 18 location of the first component 218, and thus, the animal it is 19 attached to, to be tracked via a GPS satellite system, virtually anywhere on the planet. This embodiment of the present invention 21 eliminates the need for implanting a GPS chip under the skin of an 22 animal, as is commonly done today, whicii can result in discomfort 23 the animal in many cases, as well as presenting, potentially 24 serious, health risks to others.

Looking once again to Figure 1, the present invention C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

APPLICATION FILED.DOC

1 comprises an activation assembly 38. The activation assembly 38 is 2 preferably, although not necessarily, integrated as part of a 3 handle 40 structured to facilitate holding of the leash assembly 4 during use. The handle 40 preferably includes a generally apertured construction 42 and further defines gripping means 43 6 dimensioned and configured to facilitate the holding or gripping of 7 the handle 40 by a single hand of a user of the subject leash 8 assembly. One feature of the present invention is the provision of 9 an activation member as at 44 generally in the form of a spring biased push button, which, due to the force exerted thereon by a 11 biasing spring (not shown for purposes of clarity) is preferably 12 normally disposed in an outward position as shown. The activation 13 member 44 is connected directly to a correspondingly positioned end 14 of the release structure or release cable 24. The release cable 24, may be formed of a metallic material or other applicable 16 materials. Regardless of the structural embodiments, release cable 17 24 should be sufficiently flexible to be rolled upon itself in a 18 stored position or otherwise oriented as generally shown in Figure 19 5, but should have sufficient structural integrity to be movable axially along its length, within the interior of the lead 10 and 21 relative thereto. Such axial movement may be accomplished by a 22 force ::-x~_,,,ted by the user of the subject assembly on the activation 23 member or push button 44 as indicated by directional arrow 45.

24 With reference to Figure 4, another preferred embodiment of the present invention comprises basic structural features similar C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

APPLICATION FILED.DOC

1 to the embodiment of Figures 1 and with the exception that the lead 2 10' has a somewhat flat strap like configuration extending along 3 its length. However, at least a portion of the lead 10' defines a 4 hollow interior along the entire length thereof for the positioning and axial movement of the release structure or cable 24. Moreover, 6 as illustrated in Figure 2A, a sheath structure 27 may be disposed 7 within the lead 10'.

8 The activation assembly 38' of the embodiment of Figure 4 is 9 associated with a handle structure 40' having a somewhat different configuration than that of the embodiment of Figure 1. More 11 specifically, the handle 40' comprises an open, central aperture 12 construction 42' having a grip 43' designed to facilitate gripping 13 by one hand of the user of the subject assembly. In this 14 embodiment, however, the activation assembly 38' comprises an activation member 44' in the form of a trigger type switch 16 positionable for operation by a single finger of the gripping hand 17 of the user of the subject assembly. The activation member 44' is 18 normally biased into its outermost position, as shown in Figure 4, 19 by any type of biasing spring or the like. However, depression or movement of the activation member 44' to an inner position serves 21 to axially move the release structure or cable 24. Such axial 22 movement will exert an-ollti.ward axial force on the plunger 60 which 23 will serve to release the first component 18 of the coupling 24 assembly 16 from the second component 22. Additional embodiments of the activation assembly are disclosed, such as 80' in Figure 5, C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 which is similar in structure and operation to activation assembly 2 80, as described hereinafter for the embodiment of Figure 9.

3 An additional structural feature of the embodiment of Figure 4 4 and in particular the activation assembly 38' is the inclusion of a lock structure indicated as 50. The lock structure 50 may have any 6 applicable or adequate structure secured to handle 40' so as to 7 prevent the depression or inward travel of the activation member 8 44'. This will prevent the inadvertent detachment of the coupling 9 assembly 16 and eliminate the possibility of accidentally releasing or detaching the animal from the lead 10'.

11 Yet another embodiment of the lead 10" is illustrated in 12 Figure 4A. Specifically, as shown, the lead 10" comprises a fixed 13 composite proximal portion 14" interconnected to the handle 40", 14 and a plurality of free distal ends 12". Each of the plurality of free distal ends 12" further comprising a first component 18" of a 16 coupling assembly 16" structured to interconnect to a second 17 component 22" mounted on or attached to a different one of a 18 plurality of collars, harnesses, or similar attachment assemblies 19 26, such that a single lead 10" and handle 40" may be simultaneously attached to a plurality of animals. Further, in 21 this embodiment, a selective activation member 44" is employed such 22 that the handler may select any one of the plurality of coupling 23 assemblies 16" to be released.

1 embodiment comprises a housing 84' which is structured to 2 facilitate a plurality of leads 10'. More in particular, the 3 housing 84' is structured to permit at least a portion of each of 4 the plurality of leads 10' to pass through at least a portion of the housing 84'. In addition, the housing 84' comprises an 6 activation assembly 80' which preferably includes a drive 7 mechanism, as shown in phantom at 85'. Each of the plurality of 8 leads 10' comprises a proximal portion 14' disposed in an operative 9 relationship with the housing 84', specifically, each proximal portion 14' is interconnected to at least a portion of the drive 11 mechanism 85'. Each of the leads 10' also comprises a distal end 12 12' each interconnected to a different one of a plurality of first 13 components 18' which are structured and disposed to engage a 14 corresponding one of a plurality of second components 22' (not shown) being mounted on or attached to a different one of a 16 plurality of collars, harnesses, or similar attachment assemblies 17 26' (not shown).

18 Similar to the embodiment illustrated in Figure 4A, the 19 embodiment of Figure 4B comprises a selective activation member 44' structured such that the handler may select any one of the 21 plurality of first components 18' to be released from its 22 corresponding second component 22' (not shown). In additdon, the 23 drive mechanism 85' of the embodiment of Figure 4B may be further 24 structured such that the portion of each of the plurality of leads 10' may be released from or retracted into the housing 84' either C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 independently of one another, or simultaneously and in a uniform 2 manner [i.e. substantially similar rates of release or retraction], 3 once again, via the selective activation member 44'. Thus, the 4 embodiment of the retractable leash assembly illustrated in Figure 4B provides the handler with considerable versatility in handling a 6 plurality of animals which may be attached thereto.

7 As illustrated in Figure 4B, the retractable leash assembly 8 may comprise several additional features such as a rechargeable 9 power supply 81' being electrically interconnected to a recharge port 83', the recharge port 83' preferably structured to accept a 11 standard household power source in order to recharge the 12 rechargeable power supply 81'. In at least one preferred 13 embodiment, the rechargeable power supply 81' comprises a 14 rechargeable battery pack.

Additionally, the embodiment of Figure 4B illustrates the 16 drive mechanism 85' further comprising a drive motor, shown in 17 phantom at 88', and a voice activated control module 110' disposed 18 in a communicative association with the drive motor 88'. More in 19 particular, such communicative association is at least partially defined by the drive motor 88' operating to retract the portion of 21 at least one of the plurality of leads 10' into the housing 84' or 22 to release the portion.of the lead 10' from the housing 84' upon 23 delivery of a verbal command from the user to the voice activated 24 control module 110'.

7 Yet one further embodiment of the retractable leash assembly 8 may comprise a housing 84' constructed of a clear or otherwise 9 light transmissive material and including an internal illumination source, such as one or more light emitting diodes 116', which may 11 be activated under low light conditions thus providing a safety 12 advantage to the handler, so that they may be seen by others, for 13 example, automobile drivers, while utilizing the device at night.
14 This embodiment may also comprise one or more leads 10' also being constructed of a clear or otherwise light transmissive material, 16 such that the light emitting diode(s) 116' may also act to 17 illuminate at least a portion of the leads(s) 10' thereby providing 18 an additional safety feature to the handler, as well as to the 19 animal attached thereto.

Additional preferred embodiments of the present invention are 21 shown in Figure 9, and Figures 10 and 11, and relate to an 22 activation assembly generally inuicated as at 80 or 82, 23 respectively. With regard to the embodiment of Figure 9, the 24 activation assembly 80 includes a housing 84 having an at least partially hollow interior for the mounting and enclosure of a drive C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

In at least one embodiment, 3 the drive mechanism 85 comprising at least a storage or take-up 4 spool indicated in phantom lines as 86. The take-up spool 86 is rotationally mounted on the interior of the housing 84 and, more 6 specifically, is operated by the drive mechanism 85 which may 7 further include a drive motor, such as is schematically represented 8 in phantom line as 88. The drive motor 88 is preferably 9 electrically powered and is specifically structured to be reversible so as to rotate the take-up spool 86 in opposite 11 directions. The opposite directions of rotation of the drive motor 12 88 serve to either retract or release the lead 10 thereby allowing 13 complete control over a tethered animal attached to the distal or 14 free end of the lead 10. By virtue of the drive mechanism 85 comprising the drive motor 88 and the take-up spool 86, a user or 16 handler of the subject leash assembly is allowed to avoid the 17 disadvantages associated with spring driven, retraction structures 18 of the type typically found in conventional retractable leash 19 assemblies. The drive mechanism 85 may also utilize magnetic propulsion, as described above, to further facilitate the release 21 and/or retraction of the lead 10 by the drive mechanism 85.

22 i11 one preferred embodiment, the activation ass,embly 80 23 further comprises a release control mechanism structured to 24 regulate the rate of release of the lead 10 from the housing 84 of the activation assembly 80, upon detection of a predetermined C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 condition or control set point. More specifically, the release 2 control mechanism is structured to either substantially stop the 3 release of the lead 10 from the housing 84, or to attenuate the 4 rate of release of the lead 10. The predetermined condition or set point may include a particular velocity of release of the lead 10 6 from the housing 84, or a particular acceleration of the release of 7 the lead 10 from the housing 84. In at least one embodiment, the 8 release control mechanism is structured to cooperatively associate 9 with the drive mechanism 85 to either substantially stop or attenuate the release of the lead 10 from the housing 84. In order 11 to facilitate attenuation of the release of the lead 10, the 12 release control mechanism may incorporate a computerized time delay 13 program which allows the handler to preselect a degree of 14 attenuation for the rate of release of the lead 10 from the housing 84 as appropriate, based upon the size of the animal being 16 controlled with the leash assembly. Additionally, the computer 17 program also being structured to control the velocity of the drive 18 motor 88, in accordance with the preselected degree of attenuation, 19 upon detection of the predetermined condition.

1 mounting of a drive motor 88' and a storage or take-up spool 2 generally indicated as 102. The take-up spool 102 may have a 3 spiral configuration which stores the lead 10 about the length of 4 the take-up spool 102 wherein a cushioning spring as at 104 is provided to cushion the movement of the lead 10 into and out of the 6 housing 100. Again, the drive motor 88' is structured to be 7 reversible so as to selectively accomplish both retraction and 8 release of the lead 10 relative to the take-up spool 102. A
9 switching assembly generally indicated as at 90 is also mounted on the housing 100 operatively associated with the drive motor 88' and 11 to the release structure in the form of release cable 24 as 12 explained above. As indicated above with reference to the 13 embodiment of Figure 9, the drive motor 88' may incorporate the 14 voice activated control module 110 to control the drive motor 88' to retract or release the lead 10 and/or to control the release 16 cable 24 or other release mechanism, based upon the particular 17 verbal command from the handler.

1 embodiment with a long lead 10 or wherein the lead 10 is 2 substantially wound in a stored orientation, a greater force may be 3 required to actuate the release cable 24. As such, the drive motor 4 could be used solely for the release cable 24. Additionally, whether the drive motor 88 provides for powered movement of the 6 lead 10 and/or the release cable 24, a one way drive motor could 7 also be effectively employed so long as an automatically or 8 affirmatively releasing engagement with the retracted lead 10 is 9 achieved. For example, if the lead 10 is retracted by the drive motor 88 or 88' a similar release as to that which is normally 11 provided to release an inward spring bias can be employed to allow 12 the lead 10 to be released without causing or requiring a reversal 13 of the drive motor 88 or 88'. Also, as to the release cable 24, 14 only a momentary axial force applied to the release cable 24 is required to release the first component 18 from the second 16 component 22. As such, the drive motor 88 or 88' could be 17 configured to pull on the release cable 24 a limited amount of 18 time, after which it may automatically back out after which a 19 normal bias on the release cable 24 can cause a clutch type release.

21 Another embodiment of the activation assembly 80 or 82 may 22 include the electrical power supply operatively associated with the 23 electromagnet of the alternative embodiment of the release 24 structure 24 presented above. The activation assembly 80 or 82 operates by providing sufficient electrical current to the C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 electromagnet to reverse its polarity such that it exhibits either 2 attractive or repulsive magnetic forces relative to the locking 3 members 62. The attractive or repulsive magnetic forces may cause 4 the locking members 62 to be repositioned from their normally biased outwardly extending locking orientation into their retracted 6 orientation, thereby permitting the first and second components 18' 7 and 22' to be easily released from one another. Alternatively, the 8 attractive or repulsive magnetic forces may cause the locking 9 members 62 to be repositioned from their retracted orientation into their normally biased outwardly extending locking orientation, 11 thereby securing the first and second components 18' and 22' to one 12 another.

13 In yet another embodiment, the locking members 62 may comprise 14 a shape memory alloy structured to deform from a normally biased outwardly extending locking orientation to a retracted orientation, 16 upon application of an electrical current, thereby permitting the 17 first and second components 18' and 22' to be easily released from 18 one another. Alternatively, the release cable 24 or other release 19 structure may comprise a shape memory alloy structured to deform, once again, upon application of an electrical current, thereby 21 causing the locking members 62 to be repositioned from a normally 22 biased outwardly extending locking orientation _L.ofa retracted 23 orientation, thus allowing the first and second components 18' and 24 22' to be released from one another.

1 employed to activate the electrical current to the electromagnet 2 when quick and easy release of the first and second components 18' 3 and 22' is desired. In at least one embodiment of the present 4 invention, the switching assembly 90 comprises part of an electrical circuit which directly applies the electrical current to 6 the electromagnet, while in at least one other embodiment, the 7 switching assembly 90 utilizes a fiber optic circuit which 8 indirectly causes the electrical current to be applied to the 9 electromagnet. The switching assembly 90 may further be structured so as to permit the handler to transmit a small electrical impulse 11 to the attachment assembly 26 worn by the animal, thereby directing 12 a small electrical shock, vibration, or other electrical 13 stimulation to the animal, such as have been proven to be an 14 effective training tool. In a preferred embodiment, the handler can selectively adjust the magnitude of the electrical impulse to 16 suit the size and temperament of the animal being trained.

17 Each of the embodiments of the activation assembly 80 or 82 18 comprising the drive mechanism 85 as presented herein may 19 additionally comprise a radio or other remote signal receiver structured to activate or deactivate the drive mechanism 85 and/or 21 the release cable 24 or other release mechanism from a remote 22 location via aradio transmitter. In this embodiment, a receiver-.
23 may be operatively connected to the activation assembly 80 or 82, 24 which is structured to receive predetermined signal(s) from a remotely located radio transmitter, or other remote signal C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 transmitter. Once the transmitted signal is received, the receiver 2 triggers the switch assembly 90 such that the activation assembly 3 80 or 82 causes the drive motor 88 or 88' to operate and retract or 4 release the lead 10, and/or such as to cause the release structure 24 to release the first and second components 18' and 22' from one 6 another.

7 One other embodiment of the activation assembly 80 of the 8 present invention comprises a lead aligning mechanism, generally 9 shown as 120 in Figures 12 through 17. The lead aligning mechanism 120 is structured to maintain the lead 10 in an aligned position 11 relative to the housing 84 of the activation assembly 80 as the 12 lead 10 is retracted into or released from the housing 84. More 13 specifically, the aligned position is at least partially defined 14 when the lead 10 is positioned relative to the housing 84 so as to minimize the potential for binding or other restriction of movement 16 of the lead 10 either into or from the housing 84, such as, for 17 example, when the lead 10 forms an angle of approximately ninety 18 (90) degrees with the housing at its point of entry. The 19 minimization of binding or other restriction of the lead 10 into and out of the housing provides the handler with greater control 21 over the animal being restrained by the leash assembly.

22 In one embodiment, as illusi-rated in Figures 12 through 16, 23 the lead aligning mechanism 120 is movable along at least a portion 24 of the housing 84 in an arcuate path about a central axis 87, and in at least one embodiment, the lead aligning mechanism 120 C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 comprises a moveable grip member 130. Specifically, the movable 2 grip member 130 is structured and disposed to moveably engage a 3 grip member track, such as, by way of example only, an external 4 grip member track 132, as illustrated in Figures 12 through 14. In another embodiment, the grip member track may comprise an internal 6 grip member track 133, as illustrated in Figures 15 and 16. The 7 degree of movement of the moveable grip member 130 is limited by 8 grip member track stops 135, positioned at each end of the grip 9 member track 132 or 133, when either end of the moveable grip member 136 contacts either grip member track stop 135. It is 11 understood that as the distance between the animal and the handler 12 holding the activation assembly 80 increases and decreases, the 13 angle formed between the lead and the activation assembly 80 also 14 increases and decreases, respectively. However, by virtue of the lead aligning mechanism 120 being moveable, and more specifically, 16 the moveable grip member 130 being rotatable along at least a 17 portion of the housing 84 about the central axis 87, it is also 18 understood that the lead 10 is maintained in a substantially normal 19 orientation relative to the housing 84. Thus, the lead aligning mechanism 120 minimizes the potential for binding or other 21 restriction of movement of the lead 10 into or from the housing 84, 22 w_ia-hout requiring the handler to adjust or reposition of the 23 housing 84 of the activation assembly 80 relative to the lead 10.
24 Another embodiment of the lead aligning mechanism 120 is illustrated in Figures 17 and 18. In this embodiment, the lead C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 aligning mechanism 120 comprises a movable slide member 140, which 2 is also structured to be movable along at least a portion of the 3 housing 84 of the activation assembly 80 along an arcuate path 4 about the.central axis 87. As illustrated in the figures, the movable slide member 140 comprises a slide slot 142 structured to 6 permit at least a portion of lead 10 to pass therethrough into and 7 out of the housing 84 of the activation assembly 80. The lead 8 aligning mechanism 120, in this embodiment, comprises a slide 9 member track 144 which may be mounted along an exterior portion of the housing 84, as illustrated in Figure 17. However, it is 11 understood that the slide member track 144 could be disposed along 12 the interior of the housing 84 in a similar manner as the internal 13 grip member track 133, as illustrated in Figures 15 and 16.
14 Further, in this embodiment, the housing 84 comprises a lead receiving channel 146 which is positioned substantially along the 16 path of the slide member track 144, the lead receiving channel 146 17 being wide enough to permit the lead 10 to freely pass therethrough 18 into the housing 84 regardless of the position of the moveable 19 slide member 140 along the slide member track 144. Each end 147 of the lead receiving channel 146 may serve to limit the degree of 21 movement of the moveable slide member 140 along the path of the 22 slide member trtick,,144, similar to the grip member track stops 135, 23 or alternatively, one or more slide member track stops 148 may be 24 employed.

2 The guide member 150, as shown, comprises a generally spherical 3 configuration and is structured to be moveably secured within a 4 guide seat 152, which is preferably disposed about a circumference of the guide member 150 and connected to the housing 84 of the 6 activation assembly 80. In particular, the guide member 150 is 7 structured to rotate freely about a guide axis 154 in any direction 8 or path, as illustrated by the directional arrows in Figure 20, 9 over a surface comprising substantially a hemisphere of the guide member 150 which is extending outwardly from the housing 84. The 11 guide member 150 comprises a guide channel 156 disposed 12 substantially along the guide axis 154 and structured to permit the 13 lead 10 to pass therethrough into and out of the housing 84. It is 14 understood from the figures that the lead aligning mechanism 120 comprising the guide member 150 provides the greatest range of lead 16 alignment by virtue of the fact that the guide member 150 is 17 structured to permit the lead 10 to move from side to side as well 18 as up and down relative to the housing 84 of the activation 19 assembly 80.

In the embodiment of the activation assembly 80 illustrated in 21 Figure 22, the portion of the housing 84 to which the guide member 22 150 is connected comprises awide configuration to facilitate a 23 larger directional range of movement of the lead 10, for example, 24 from side to side and up and down relative to the housing 84.

Figure 23 illustrates yet another embodiment of the activation C:\DOCUMENTS AND SETTINGS\MRO\LOCAL SETTINGS\TEMPORARY INTERNET

1 assembly 80 wherein the housing 84 comprises a generally spherical 2 configuration. In this embodiment, the take-up spool 86 is 3 structured such that the lead 10 also comprises a substantially 4 spherical configuration within the housing 84, as it is wound onto the take-up spool 86.

6 Yet another embodiment of an activation assembly 80 is 7 illustrated in Figure 24. In particular, the embodiment of Figure 8 24 illustrates the activation assembly comprising a composite lead 9 aligning mechanism 120'. As shown in the figure, the composite lead aligning mechanism 120' comprises a moveable grip member 130, 11 similar to the embodiment of Figures 15 and 16, and a guide member 12 150, as illustrated in Figures 19, 20, 22, and 23. The composite 13 lead aligning mechanism 120' allows the lead to move freely in both 14 arcuate and rotational directions relative to the housing 84 of the activation assembly 80.

16 Since many modifications, variations and changes in detail can 17 be made to the described preferred embodiment of the invention, it 18 is intended that all matters in the foregoing description and shown 19 in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be 21 determined by the appended claims and their legal equivalents.
