member 2000 upward ; 9 ) allows the elongated member 2000 to ultimately span an effective range of motion typically from at least 90 degrees ( mid - pull ) to more than 180 degrees ( at final zipper closure ) from the elongated member &# 39 ; s initial parallel position when completely adjacent to the zipper slide 500 and zipper teeth 510 ( or the same effective range but in reverse when the device is being actuated to open the zipper ), 10 ) gains traction by pulling the elongated member 2000 with frictional force in an upward lateral direction behind the user &# 39 ; s head and towards the front of the user ( over the user &# 39 ; s shoulder or head ); 11 ) completes the zipper &# 39 ; s operation by engaging the zipper slide 550 with the zipper &# 39 ; s terminal end 520 ; 12 ) disengages the zipper pull tab 550 from the engagement device 1000 with no damage or permanent changes to the garment &# 39 ; s zipper or functionality ; 13 ) collapses the elongated member &# 39 ; s 2000 extended sections within the elongated member ; and 14 ) stores the device in its collapsed state to avoid altering or enmeshing it with other objects to ensure the continued design , function or usability of the apparatus . to remove the garment , the foregoing procedure is carried out in reverse order . the foregoing description is intended for illustration only , and is not intended to limit the scope of the claimed invention . referring now to fig2 a and 2b , another embodiment of the present invention is shown . the structure of the embodiment shown in fig2 a and 2b is similar to the structure shown in fig1 a , 1 b , and 1 c except that the embodiment of fig2 a also includes an engagement pin 1150 . in operation , referring to fig2 c , engagement pin 1150 extends through an aperture 557 in the zipper pull tab 550 , creating a secure connection between engagement device 1100 and the zipper pull tab 550 . while pull tab 550 is the most common embodiment of a zipper pull tab and is commonly referred to as the ykk ® pull tab , in operation , referring to fig2 c , engagement pin 1150 extends through an aperture 557 in zipper pull tab 500 , creating a secure connection between the engagement device 1600 and the zipper pull tab 550 the length and diameter of pin 1100 can be varied as desired to fit a specific type of zipper structure . in one preferred embodiment , the pin is 5 / 16 inch in length and 1 / 16 inch in diameter . referring to fig2 b , which shows a bottom view of the embodiment shown in side view in fig2 a , lower engagement structure 1120 includes an aperture 1127 that receives pin 1150 when the upper engagement surface 1115 and lower engagement surface 1125 are proximate one another . aperture 1127 is shown as a recess in structure 1020 , but it could also be an enclosed hole that receives pin 1100 . instead of pin 1100 , a tang or any other structure suitable to interface with an aperture on the zipper structure may be used . fig2 d shows operation by a user 100 of the embodiment described in connection with fig2 a , 2 b , and 2 c . the description for the operation of the embodiment shown in fig1 a , 1 b , and 1 c is applicable to this embodiment as well . however , here the user 100 causes the pin 1150 to extend through an aperture 557 in zipper pull tab 550 when securing the engagement device 1100 to the zipper structure . fig2 e , 2 f , 2 g , and 2 h show another embodiment of the present invention in which pin 1150 is extended through the aperture created by structure 540 that connects pull tab 550 a to slider 500 a . this embodiment is useful when a pull tab , such as pull tab 550 a , does not have an aperture through which pin 1150 can be extended . the operation of this embodiment is similar to the operation described in connection with fig2 d except that pin 1150 extends through the aperture created by structure 540 rather than through the aperture 557 in pull tab 550 . in the embodiments shown in fig2 e , 2 f , and 2 g , pull tab 550 a is at an angle of approximately 20 degrees to the longitudinal axis of engagement device 1100 , and may be at any other suitable angle and is not limited to approximately 20 degrees . in the embodiment shown in fig2 h , the longitudinal axis of pull tab 550 a is approximately parallel to the longitudinal axis of engagement device 1100 . referring to fig3 a , 3 b , and 4 an alternate embodiment of the present invention using a tweezer configuration is shown . in this embodiment , engagement device 1200 utilizes a tweezer structure . a slide 1250 is moved towards the outer end of device 1200 to direct the upper and lower engagement structures 1210 and 1220 from an open position , as shown in fig3 a , to a closed position as shown in fig3 b . the upper and lower engagement surfaces 1215 and 1225 are located at a greater distance apart in the open position when compared to the closed position . in the closed position , the upper and lower engagement surfaces are interfaced with a zipper structure for operation of the present invention . in an alternate embodiment as shown in fig4 , the tweezer configuration can further include a tang 1217 at the outer end of upper engagement structure 1210 . tang 1217 can be used to interface with an aperture on the zipper structure to provide a more secure connection between the engagement device 1200 and zipper structure . instead of tang 1217 , a pin or any other structure suitable to interface with an aperture on the zipper structure may be used . in addition , tang 1217 ( or any other similar structure ) can be positioned at an angle normal to ( e . g ., approximately ninety degrees ) the longitudinal axis of the engagement structure . referring to fig5 a and 5b , an alternate embodiment of the present invention using a cam structure is shown . in this embodiment , a cam 1310 operated by an arm 1320 engages a pull tab 600 . it should be understood that this embodiment can be used in connection with zipper pull tabs and other zipper structures having a variety of shapes and is not limited to use in connection with the shape of pull tab 600 . in fig5 a , the engagement structure 1300 is in a “ locked ” position , as arm 1320 is directed in a closed position thereby causing cam 1310 to apply force against pull tab 600 , resulting in a frictional and mechanically limiting engagement between the engagement structure 1300 and the zipper pull tab 600 . in fig5 b , the engagement structure 1300 is shown in an unlocked position . in operation , the zipper structure , such as a zipper pull tab 600 , is engaged by the cam 600 when in the locked position as shown in fig5 a . the zipper pull tab 600 is released by placing the engagement device in an unlocked state , as shown in fig5 b . in another embodiment of the present invention ( not shown ) magnets can be mounted to the outer facing surfaces of the first and second engagement structures . the magnets can be used to create both an attractive and repulsive force between the engagement structures depending upon the orientation of the magnets towards one another . referring to fig6 , another alternate embodiment of the present invention is shown . here , engagement device 1400 is a resiliently coiled wire , similar in shape and design to the coil used on a cooking whisk such as a twirl whisk or french whisk . the coiling serving as the outer end 1410 of engagement device is typically of a reduced diameter when compared to the prior coil , and may contain a coating on the tip to prevent snagging . this thin tip 1410 can be thread through the smallest hole void or pull tab attachment piece . the outer end 1410 also is configured to abut again the prior coil , leaving a smaller gap when compared with the gap between prior coils . in operation , the outer end 1410 of engagement device 1400 is extended through an aperture in the zipper structure , thereby forming releasable engagement between the engagement device 1400 and zipper structure . the abutment of the outer end 1410 to the prior coil creates a secure connection to the zipper structure ( not shown ) in a manner similar to that of the connection make between a key and conventional key ring . this connection allows the outer end 1410 and the pull tab to be incorporated and housed within the center of the coiled wire to prevent dislodgement or unintentional detachment to allow for maximal engagement of the pull tab while preventing outer end 1410 from contact with the zipper structure or fabric proximally adjacent to the zipper structure . engagement structure 1400 is typically flexible , which permits a wide range of motion to account for physical limitations of the user during operation of the present invention . referring now to fig7 a , another alternate embodiment is shown in which engagement device 1500 includes a first friction - enhancing coating 1517 on first engagement surface 1515 and a second friction - enhancing coating 1527 on second engagement surface 1525 . in one embodiment , friction enhancing coatings 1517 and 1527 is a memory foam that forms around a zipper pull tab 600 , or other similar pull tab that in some embodiments may lack a hole or aperture in the pull tab itself . in addition to memory foam , other friction enhancing materials can be used such as rubber , mild abrasives , silicone , gels , and other materials that increase the frictional engagement between the engagement device 1500 and zipper pull tab 600 and optionally deform around the contour of the pull tab 600 to provide a more secure connection between a zipper structure and the engagement device . this embodiment is especially useful in connection with zipper pull tabs that have irregular contour shapes , such as those frequently found on ann taylor ® dresses , gowns , or other garments , as well as pull tabs that do not have apertures through which a pin can be extended but may have an opening or aperture in the connection of the pull tab to the zipper slider that can accommodate a pin . in addition , the use of such coatings can prevent the zipper pull tab from becoming scratched or otherwise damages during use of the present invention . fig7 b shows a top view of the embodiment first shown in fig7 a . in addition , fig7 b shows how the zipper pull tab 600 is engaged by the engagement structure 1500 from a top view perspective . referring to fig7 c , the embodiment shown in fig7 a is shown in an open position in which the first and second engagement structures 1510 and 1520 are positioned in a direction away from one another to create a space in which zipper pull tab 600 can be positioned . fig7 d then illustrates engagement structures 1510 and 1520 in a closed position to create an engagement with zipper pull tab 600 . the first and second friction enhancing coatings are shown in engagement with pull tab 600 . the friction enhancing coating of this embodiment can also be used in connection with other embodiments described herein . referring now to fig8 a , an alternate embodiment is shown in which engagement device 1600 is shaped to fit the contours of zipper pull tab 600 . the side surfaces 1611 and 1613 of engagement structure 1610 are concaved inwards to mesh with the concaved shape of zipper pull tab 600 . the side surfaces ( not shown ) of engagement structure 1620 are likewise concaved inwards to mesh with the shape of pull tab 600 . the contoured shape of the engagement structures results in a more secure connection between the engagement device 1600 and zipper pull tab 600 because the concaved surface provide an additional engagement surface that prevents the zipper pull tab 600 from disengaging from the engagement device 1600 . fig8 b shows the first and second engagement structures in a closed position , thereby engaging pull tab 600 . referring to fig9 , an alternate embodiment is shown in which engagement device 1700 is configured in a “ shepherd &# 39 ; s hook ” design . the engagement device is generally shaped like a hook , and the outer end 1710 of device 1700 is inwards and then flared outwards , creating a more secure connection between the engagement device and zipper structure and making it easier to position the outer end 1710 through an aperture in a zipper structure ( not shown ). referring to fig1 , an alternate embodiment is shown in which the engagement structure 1800 is shaped in decorative manner , here to resemble a fish . the structure and operation of the engagement structure 1800 is similar to the structure and operation of engagement structure 1100 as shown in fig2 a , 2 b , 2 c , and 2 d . in another embodiment ( not shown ) engagement structure 1800 may optionally omit pin 1810 , in which case engagement structure 1800 would operates in the fashion similar to that of engagement structure 1000 in fig1 a , 1 b , and 1 c . the other engagement devices described herein also can be shaped in a decorative manner . referring to fig1 , the engagement device 1800 of the present invention ( as well as any other engagement device ) can use an elongated member made of a flexible material 3000 such as a fabric tape , cord , or other suitable flexible material . this flexible material 3000 can be coiled in a storage case 4000 in a fashion similar to that of a retractable measuring tape or other similar retractable devices . this retractable , flexible material 3000 can be selectively locked into a desired length , resulting in an operation similar to that of the locking , telescoping elongated member described above . referring to fig1 a , the engagement device 1900 of the present invention is structurally and operationally similar to a conventional jewelry clasp . as shown in fig1 b , the latch 1910 can be selectively opened and closed to permit device 1900 to engage a zipper pull tab 550 through an aperture in the structure . those skilled in the art will appreciate that numerous modifications and variations may be made to the above disclosed embodiments without departing from the spirit and scope of the present invention . the accompanying drawings also illustrate by way of example only — and not limitation — the principles of and preferred modes of applying these principles and are not necessarily to scale .
a zipper operating device for closing or opening a zipper located at the back of a garment or where accessibility for manipulation is awkward , inconvenient or otherwise difficult . this zipper operating device can engage almost all zipper pull tabs , including those elongated pull tabs without voids or holes .
