Abstract
Description
- This application claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 62/961,321, filed Jan. 15, 2020, the entire contents of which is incorporated herein by reference.
- Various pulls are known. For example, a zipper pull is attachable to a bale of a slider of a zipper to enable a person using the zipper (such as a zipper on a backpack) to easily operate the zipper.
- One known zipper pull includes a single loop formed by a material cord and an over-molded plastic cover on part of the material cord. This type of zipper pull is relatively expensive due to the multiple different materials used to form this zipper pull, the labor required to assemble this zipper pull, and the labor required to attach this zipper pull to a zipper on or for a product. These materials used to make this type of zipper pull can easily break and can be readily worn out such as by the weather or other environmental conditions.
- Accordingly, there is a continuing need for pulls (such as zipper pulls) that are less expensive to make and attach to zippers, and that are more durable.
- Various embodiments of the present disclosure provide a pull such as a zipper pull that is formed from a single material, that is easily attachable to an object such as a bail of a slider of a zipper, and that is extremely durable. In various embodiments of the present disclosure, the pull includes an attachment loop, a gripping loop, and a loop connector connecting the attachment loop to the gripping loop. The attachment loop is sized and configured to be attached to an object, and the attachment loop and the loop connector are sized and configured to prevent the disengagement of the attachment loop from the object. The gripping loop is sized and configured to receive and/or be engaged by a user (such as by one or more fingers of a user) to enable the user to engage and exert force on the pull in a suitable direction and thus move the object to which the pull is attached. The pull enables the user to suitably grip the pull and place suitable forces on the object.
- In various embodiments, the pull includes an attachment loop, a gripping loop, and a loop connector connecting the attachment loop to the gripping loop. The loop connector includes a first joint connecting the attachment loop to the gripping loop and a second joint connecting the attachment loop to the gripping loop. The first joint and the second joint are spaced apart and independently operable.
- In various embodiments, the pull includes an attachment loop having a partially circular shape, a gripping loop larger than the attachment loop and having a partially teardrop shape, and a loop connector connecting the attachment loop to the gripping loop.
- In various embodiments, the pull includes an attachment loop including a head, a first arm connected to and extending from a first end section of the head, a second arm connected to and extending from a second end section of the head. The pull also includes a gripping loop including a gripping seat, a first leg connected to and extending from a first end section of the gripping seat, and a second leg connected to and extending from a second end section of the gripping seat. The pull further includes a loop connector including a first joint connecting the first arm of the attachment loop to the first leg of the gripping loop, and a second joint connecting the second arm of the attachment loop to the second leg of the gripping loop, wherein the first joint and the second joint are spaced apart and independently operable, wherein the first joint of the loop connector includes a member bent is a first direction, and the second joint includes a member bent is a second direction that is opposite the first direction. In various such embodiments, the attachment loop, the gripping loop, and the loop connector are monolithically formed from a rigid plastic material.

- Turning now to the drawings,
FIGS. 1 to 9 illustrate a pull of one example embodiment of the present disclosure that is generally indicated bynumeral 50. Thepull 50 is configured to be attached to an object (such as but not limited to a bail of a slider of a zipper) for assisting in pulling that object relative to a product (such as a backpack) to which that object is attached. - More specifically, this illustrated
example pull 50 includes: (1) anattachment loop 100; (2) agripping loop 200; and (3) aloop connector 300 connecting theattachment loop 100 to thegripping loop 200. Theattachment loop 100 is sized and configured to be attached to an object (such as but not limited to abail 600 of aslider 550 of azipper 500 attached to aproduct 800 such as shown inFIG. 8 ). Theattachment loop 100 and theloop connector 300 are sized and configured to prevent the disengagement of theattachment loop 100 from the object (such as theslider 550 of thezipper 500 as shown inFIG. 8 ). Thegripping loop 200 is sized and configured to receive and be engaged by a user (such as by afinger 900 of a user as shown inFIG. 9 ) to enable the user to engage and exert force on thepull 50 in a suitable direction and thus move the object (such as theslider 550 of thezipper 500 as shown inFIG. 9 ) to which thepull 50 is attached. Thepull 50 has somewhat of aFIG. 8 shape and a continuous loop configuration that facilitates attachment and pulling operations and enables for twisting of thepull 50 as described below. Thepull 50 is sized and configured to enable the user to strongly grip the pull and place suitable forces on the object (such as theslider 550 of the zipper 500). It should be appreciated that while thepull 50 of the present disclosure is described and shown herein in connection with use with a zipper, the pull can be used with other suitable objects in accordance with the present disclosure. - The
pull 50 including theattachment loop 100, thegripping loop 200, and theloop connector 300 are integrally connected and specifically suitably monolithically formed (such as via injection molding) in this illustrated example embodiment. Thepull 50 including theattachment loop 100, thegripping loop 200, and theloop connector 300 are formed from a suitable relatively rigid plastic material in this illustrated example embodiment. In one such example embodiment, the relativelyrigid pull 50 is formed from a Polyoxymethylene (POM) (that is also known as an acetal, polyacetal, and a polyformaldehyde). It should be appreciated that this single material configuration enables mass production of thepull 50 at relatively low cost. It should be appreciated that the pull can be formed in other suitable manners and from other suitable materials in accordance with the present disclosure such as described below. - In this illustrated example embodiment, as best shown in
FIGS. 2 to 6 , theattachment loop 100 includes: (a)head 110; (b) afirst arm 130 connected to and extending from afirst end section 112 of thehead 110; and (c) asecond arm 160 connected to and extending from asecond end section 116 of thehead 110. Thehead 110, thefirst arm 130, and thesecond arm 160 are configured to be attached to an object such as but not limited to abail 600 of aslider 550 of azipper 500 as shown inFIGS. 8 and 9 . - More specifically, the
head 110 includes a cylindrical uniform solid curved member having afirst end section 112, anintermediate section 114, and asecond end section 116. Thehead 110 has atop convex surface 118, an innerconcave surface 120, a curvedfirst side surface 122, and a curvedsecond side surface 124. - The
first arm 130 includes a cylindrical uniform solid curved member having afirst end section 132 connected to thefirst end section 112 of thehead 110, anintermediate section 134, and asecond end section 136 connected to theloop connector 300 as further explained below. Thefirst arm 130 has a convexouter surface 140, a concaveinner surface 142, a curvedfirst side surface 144, and a curvedsecond side surface 146. - Likewise, the
second arm 160 includes a cylindrical uniform solid curved member having afirst end section 162 connected to thesecond end section 116 of thehead 110, anintermediate section 164, and asecond end section 166 connected to theloop connector 300 as further explained below. Thesecond arm 160 has a convexouter surface 170, a concaveinner surface 172, a curvedfirst side surface 174, and a curvedsecond side surface 176. - The
first arm 130 and thesecond arm 160 are curved in opposite directions such that: (1) theouter surface 140 of thefirst arm 130 and theouter surface 170 of thesecond arm 160 face in opposite directions; (2) theinner surface 142 of thefirst arm 130 and theinner surface 172 of the second am 160 face each other; (3) thefirst side surface 144 of thefirst arm 130 and thefirst side surface 174 of thesecond arm 160 face in the same direction; and (4) thesecond side surface 146 of thefirst arm 130 and thesecond side surface 176 of thesecond arm 160 face in the same direction. - In this example embodiment, the
head 110, thefirst arm 130, and thesecond arm 160 are formed of rigid plastic material that: (1) limits thefirst arm 130 and thesecond arm 160 from being pulled away from each other in the directions of theirouter surfaces second end section 136 of thefirst arm 130 and thesecond end section 166 of thesecond arm 160 from being pulled away from each other in the directions of theirouter surfaces head 110, thefirst arm 130, and thesecond arm 160 are also formed: (1) to limit thesecond end section 136 of thefirst arm 130 from being pulled away from thehead 110; and (2) to limit thesecond end section 166 of thesecond arm 160 from being pulled away from thehead 110. Thus, the relevant movement of these parts of theattachment loop 100 is limited in the longitudinal direction of thepull 50. - In this example embodiment, the rigid plastic material of the
head 110, thefirst arm 130, and thesecond arm 160 enable certain transverse (to the longitudinal direction) movements of thefirst arm 130 and thesecond arm 160 relative to each other. In other words, thesecond end section 136 of thefirst arm 130 and thesecond end section 166 of thesecond arm 160 can move or be being pulled away from each other in the directions of their opposite outer side surfaces and will each be biased back to their respective resting positions. In other words, thefirst arm 130 can move in a direction of itsfirst side surface 144, and thesecond arm 160 can move in a direction of its second side surface 176 (i.e., in opposite directions), and will each be biased back to their respective resting positions. Likewise, thefirst arm 130 can move in a direction of itssecond side surface 146, and thesecond arm 160 can move in a direction of its first side surface 174 (i.e., in opposite directions), and will each be biased back to their respective resting positions. Thus, certain relative movements of these parts of theattachment loop 100 is allowed in the transverse directions of thepull 50, and thus thepull 50 is flexible in those directions. - It should be appreciated from the above that the
attachment loop 100 of thepull 50 has more rigidity in the longitudinal direction than in the transverse direction in this example embodiment of the present disclosure. - In this illustrated example embodiment, the
gripping loop 200 includes: (a) agripping seat 210; (b) afirst leg 230 connected to and extending from afirst end section 212 of thegripping seat 210; and (c) asecond leg 260 connected to and extending from asecond end section 216 of thegripping seat 210. In this illustrated example embodiment, theattachment loop 100 is significantly smaller than thegripping loop 200. Specifically, thegripping loop 200 is 6 to 7 times the size of theattachment loop 100 in this example embodiment. It should be appreciated that the relative sizes and thicknesses of theattachment loop 100 and thegripping loop 200 may vary in accordance with the present disclosure. - More specifically, the
gripping seat 210 includes a curved body having afirst end section 212, anintermediate section 214, and asecond end section 216. Thegripping seat 210 has a bottomconvex surface 218, an innerconcave surface 220, afirst side surface 222, and asecond side surface 224. As best shown inFIGS. 2 and 3 , thegripping seat 210 has a height that narrows from theintermediate section 214 of thegripping seat 210 to and through thefirst end section 212 of thegripping seat 210 and from theintermediate section 214 of thegripping seat 210 to and through thesecond end section 216 of thegripping seat 210. As best shown inFIGS. 4 and 5 , thegripping seat 210 has a width that narrows from theintermediate section 214 of thegripping seat 210 to and through thefirst end section 212 of thegripping seat 210 and from theintermediate section 214 of thegripping seat 210 to and through thesecond end section 216 of thegripping seat 210. - The
gripping seat 210 and particularly theintermediate section 214 of thegripping seat 210 includes anupper section 210 a and alower section 210 b that together define an inner crescent shaped opening 226 defined by an inner convextop surface 226 a and an inner concavebottom surface 226 b. The convextop surface 226 a extends from thefirst side surface 222 to thesecond side surface 224. Theconcave bottom surface 226 b also extends from thefirst side surface 222 to thesecond side surface 224. Thegripping seat 210 and particularly theintermediate section 214 of thegripping seat 210 also includes two spaced-apartconnection walls top surface 226 a and theconcave bottom surface 226 b. Theseconnection walls upper section 210 a and thelower section 210 b of theintermediate section 214 of thegripping seat 210. Theseconnection walls upper section 210 a from thelower section 210 b. This configuration of thegripping seat 210 with the opening 226 saves some material in the manufacturing process and provides an enhanced overall look forpull 50. - The
first leg 230 of thegripping loop 200 includes a cylindrical uniform solid partially curved member having afirst end section 232 connected to thefirst end section 212 of thegripping seat 210, anintermediate section 234, and asecond end section 236 connected to theloop connector 300 as further explained below. Thefirst leg 230 has a greater radius of curvature from thefirst end section 232 to theintermediate section 234 than from theintermediate section 234 to thesecond end section 236. Thefirst leg 230 has a partially convexouter surface 240, a partially concaveinner surface 242, a curvedfirst side surface 244, and a curvedsecond side surface 246. - Likewise, the
second leg 260 of thegripping loop 200 includes a cylindrical uniform solid partially curved member having afirst end section 262 connected to thesecond end section 216 of thegripping seat 210, anintermediate section 264, and asecond end section 266 connected to theloop connector 300 as further explained below. Thesecond leg 260 has a greater radius of curvature from thefirst end section 262 to theintermediate section 264 than from theintermediate section 264 to thesecond end section 266. Thesecond leg 260 has a partially convexouter surface 270, a partially concaveinner surface 272, a curvedfirst side surface 274, and a curvedsecond side surface 276. - The
first leg 230 and thesecond leg 260 are partially curved in opposite directions such that: (1) theouter surface 240 of thefirst leg 230 and theouter surface 270 of thesecond leg 260 face in opposite directions; (2) theinner surface 242 of thefirst leg 230 and theinner surface 272 of thesecond leg 260 face each other; (3) thefirst side surface 244 of thefirst leg 230 and thefirst side surface 274 of thesecond leg 260 face in the same direction; and (4) thesecond side surface 246 of thefirst leg 230 and thesecond side surface 276 of thesecond leg 260 face in the same direction. - In this example embodiment, the
gripping seat 210, thefirst leg 230, and thesecond leg 260 are formed of rigid plastic material that: (1) limits thefirst leg 230 and thesecond leg 260 from being pulled away from each other in the directions of theirouter surfaces second end section 236 of thefirst leg 230 and thesecond end section 266 of thesecond leg 260 from being pulled away from each other in the directions of theirouter surfaces gripping seat 210, thefirst leg 230, and thesecond leg 260 are also formed: (1) to limit thesecond end section 236 of thefirst leg 230 from being pulled away from thegripping seat 210; and (2) to limit thesecond end section 266 of thesecond leg 260 from being pulled away from thegripping seat 210. Thus, the relevant movement of these parts of thegripping loop 200 is limited in the longitudinal direction of thepull 50. - In this example embodiment, the rigid plastic material of the
gripping seat 210, thefirst leg 230, and thesecond leg 260 enable certain transverse (to the longitudinal direction) movements of thefirst leg 230 and thesecond leg 260 relative to each other. In other words, thesecond end section 236 of thefirst leg 230 and thesecond end section 266 of thesecond leg 260 can move or be being pulled away from each other in the directions of their opposite outer side surfaces and will each be biased back to their respective resting positions. In other words, thefirst leg 230 can move in a direction of itsfirst side surface 244, and thesecond leg 260 can move in a direction of its second side surface 276 (i.e., in opposite directions), and will each be biased back to their respective resting positions. Likewise, thefirst leg 230 can move in a direction of itssecond side surface 246, and thesecond leg 260 can move in a direction of its first side surface 274 (i.e., in opposite directions), and will each be biased back to their respective resting positions. Thus, certain movement of these parts of thegripping loop 200 is allowed in the transverse direction of thepull 50. - It should be appreciated from the above that the
gripping loop 200 of thepull 50 has more rigidity in the longitudinal direction than in the transverse direction in this example embodiment of the present disclosure. - In this illustrated example embodiment, the
loop connector 300 includes: (1) a first joint 330 connecting thefirst arm 130 of theattachment loop 100 to thefirst leg 230 of thegripping loop 200; (2) a second joint 360 connecting thesecond arm 160 of theattachment loop 100 to thesecond leg 260 of thegripping loop 200; and (3) aconnection web 390 temporarily connecting the first joint 330 to thesecond joint 360. - As best shown in
FIG. 2 , thefirst joint 330 of theloop connector 300 looks somewhat like an elbow. The first joint 330 includes a bent cylindrical uniform solid member having afirst end section 332 connected to thesecond end section 136 of thefirst arm 130, anintermediate section 334, and asecond end section 336 connected to thesecond end section 266 of thefirst leg 300. The first joint 330 has a concaveouter surface 340, a convexinner surface 342, a curvedfirst side surface 344, and a curvedsecond side surface 346. - Likewise, the
second joint 360 of theloop connector 300 looks somewhat like an elbow. The second joint 360 includes a bent cylindrical uniform solid member having afirst end section 362 connected to thesecond end section 166 of thesecond arm 160, anintermediate section 364, and a second end section 366 connected to thesecond end section 266 of thesecond leg 260. The second joint 360 has a concaveouter surface 370, a convexinner surface 372, a curvedfirst side surface 374, and a curvedsecond side surface 376. - The first joint 330 and the second joint 360 are bent in opposite directions such that: (1) the
outer surface 340 of the first joint 330 and theouter surface 370 of the second joint 360 face in opposite directions; (2) theinner surface 342 of the first joint 330 and theinner surface 372 of the second joint 360 face each other; (3) thefirst side surface 344 of the first joint 330 and thefirst side surface 374 of the second joint 360 face in the same direction; and (4) thesecond side surface 346 of the first joint 330 and thesecond side surface 376 of the second joint 360 face in the same direction. - The
connection web 390 is configured to temporarily connect the first joint 330 to the second joint 360 during manufacturing, and particularly theintermediate section 334 of the first joint 330 to theintermediate section 364 of the second joint. During manufacturing this connection web forms a flash junction between such parts to enable theintermediate section 334 of the first joint 330 to be positioned close to theintermediate section 364 of the second joint with a relatively small gap between such parts. In other words, the flash junction enables the small gap between the first and second joint to be made during the injection molding process. The very small gap enables thepull 50 to have the transverse flexibility described herein while limiting the likelihood that the attachment loop will be dislodged from the object to which thepull 50 is attached. Thisconnection web 390 is configured to be broken during the manufacturing process or thereafter such as before attachment of thepull 50 and particularly theattachment loop 100 of thepull 50 to an object such as abail 600 of aslider 550 of azipper 500 as shown inFIGS. 8 and 9 . After theconnection web 390 is broken, the first joint 330 and the second joint 360 are spaced apart, separate, independently operable, and not directly connected to each other. - In this example embodiment, the first joint 330 and the second joint 360 are formed of rigid plastic material that limits the first joint 330 and the second joint 360 from being pulled away from each other in the directions of their
outer surfaces loop connector 300 is limited in the longitudinal direction of thepull 50. - In this example embodiment, the rigid plastic material of the first joint 330 and the second joint 360 enable certain transverse (to the longitudinal direction) movements of the first joint 330 and the second joint 360 relative to each other. In other words, the first joint 330 and the second joint 360 can move or be pulled away from each other in the directions of their opposite outer side surfaces and will each be biased back to their respective resting positions. In other words, the first joint 330 can move in a direction of its
first side surface 344, and the second joint 360 can move in a direction of its second side surface 376 (i.e., in opposite directions), and will each be biased back to their respective resting positions. Likewise, the first joint 330 can move in a direction of itssecond side surface 346, and the second joint 360 can move in a direction of its first side surface 374 (i.e., in opposite directions), and will each be biased back to their respective resting positions. Thus, certain movement of these parts of theloop connector 300 is allowed in the transverse direction of thepull 50. - It should be appreciated from the above that the
loop connector 300 of thepull 50 has more rigidity in the longitudinal direction than in the transverse direction in this example embodiment of the present disclosure. - It should also be appreciated from the above that the
entire pull 50 has more rigidity in the longitudinal direction than in the transverse direction in this example embodiment of the present disclosure. - This longitudinal rigidity of the
pull 50 and particularly of theattachment loop 100 and theloop connector 300 assists in keeping thepull 50 attached to thebail 600 of theslider 550 of thezipper 500 as shown inFIGS. 8 and 9 . In that regard, as shown inFIGS. 8 and 9 , it should be appreciated that acommon zipper 500 includes two halves often called stringers (not labeled) that have interlocking links (not labeled) that are zipped and unzipped by theslider 550 having thebail 600. As shown inFIGS. 8 and 9 , thepull 50 is attachable to thebail 600 of theslider 550 when thebail 600 is opened (and then subsequently closed after insertion of thehead 110 of theattachment loop 100 under the bail 600). A user can either grip thegripping loop 200 with two fingers or can insert one of their fingers in the gripping loop 200 (as shown inFIG. 9 ) to apply force to thepull 50 to make theslider 550 slide along the stringers. It should also be appreciated that this configuration of thepull 50 enables thepull 50 to move or twist around thebail 600 and return to its normal position. - In alternative embodiments of the present disclosure, the pull does not have an overall figure-eight shape like
pull 50, but rather has a different overall shape. - In alternative embodiments of the present disclosure, the gripping loop does not have the crescent shaped opening, but rather has a differently shaped opening.
- In alternative embodiments of the present disclosure, the gripping loop does not have any opening.
- In alternative embodiments of the present disclosure, the gripping loop does not have any opening and is made from a cylindrical uniform solid curved member with no varying heights or widths.
- In alternative embodiments of the present disclosure, the attachment loop, the gripping loop, and/or the loop connector have one or more sections that are not made from a cylindrical uniform solid curved member, but are made from a member having: (1) a different outer shape; (2) a non-uniform shape; and/or (3) a tubular configuration.
- In alternative embodiments of the present disclosure, the attachment loop has an alternative overall shape other than having a generally or partially circular shape.
- In alternative embodiments of the present disclosure, the gripping loop has an alternative overall shape other than having a generally or partially tear-drop shape.
- In a further alternative embodiment of the present disclosure, the pull including the attachment loop, the gripping loop, and the loop connector are formed from a suitable relatively flexible plastic material such as a more flexible plastic or rubber material that additionally enables the pull to be more flexible in the longitudinal direction (in addition to the transverse direction as described above). In this alternative embodiment, the head, the first arm, and the second arm of the attachment loop are formed such that: (1) when the first arm and the second arm are pulled away from each other, they are biased to return to toward each other to their respective resting positions; and (2) when the second end section of the first arm and the second end section of the second arm are pulled away from each other, they are biased to return to toward each other to their respective resting positions. Likewise, in this alternative embodiment, the head, the first arm, and the second arm of the attachment loop are formed such that: (1) when the second end section of the first arm is pulled away from the head, the second end section is biased to return toward its resting position; and (2) when the second end section of the second arm is pulled away from the head, the second end section is biased to return toward its resting position. It should thus be appreciated in this alternative embodiment that each of the first arm and the second arm are extendable to a plurality of outward and/or downward positions and in such positions, they each will be biased back to their respective resting positions.
- Likewise, in this alternative embodiment, the gripping seat, the first leg, and the second leg are formed such that: (1) when the first leg and the second leg are pulled away from each other, they are each biased to return to toward each other to their resting positions; and (2) when the second end section of the second leg and the second end section of the first leg are pulled away from the each other, they are each biased to return to toward each other to their resting positions. The gripping seat, the first leg, and the second leg are also formed in this alternative embodiment such that: (1) when the second end section of the first leg is pulled away from the gripping seat, the second end section is biased to return toward its resting position; and (2) when the second end section of the second leg is pulled away from the gripping seat, the second end section is biased to return toward its resting position. It should be appreciated that in this alternative embodiment each of the first leg and the second leg are extendable to a plurality of outward and/or upward positions and in such positions, they each will be biased back to their respective resting positions. This alternative embodiment also accommodates forces placed on the gripping seat and particularly the intermediate section of the gripping seat by a user's finger(s), and facilitates compression of the intermediate section of the gripping seat including movement of the upper section toward the lower section, and the respective return of these upper and lower sections to their resting positions after pressure on such sections is released.
- In this alternative embodiment, the loop connector includes: (1) an expandable first joint connecting the first arm of the attachment loop to the first leg of the gripping loop; (2) an expandable second joint connecting the second arm of the attachment loop to the second leg of the gripping loop; and (3) a connection web temporarily connecting the first joint to the second joint. The expandable first joint of the loop connector looks and functions somewhat like an elbow that is biased back to its resting position. The first joint has a resting position and an plurality of expanded positions (not shown), and is biased toward this resting position. The first joint is configured to expand (thus moving through a plurality of the expanded positions when the gripping loop is pulled, and then back to the resting position when the gripping loop is released. Likewise, the second joint of the loop connector looks and functions somewhat like an elbow that is biased back to its resting position. The second joint has a resting position and a plurality of expanded positions (not shown), and is biased toward this resting position. The second joint is configured to expand (thus moving through a plurality of expanded positions when the gripping loop is pulled, and then back to the resting position when the gripping loop is released. In this alternative embodiment, the first joint and the second joint may: (1) expand the same amounts; (2) retract the same amounts; (3) expand at the same rates; (4) retract at the same rates; (5) expand different amounts; (6) retract different amounts; (7) expand at different rates; or (8) retract at different rates, depending on the forces and the directions of the forces applied to the gripping loop. In other words, the first and second joints can work together or separately for expansion and contraction.
- Further alternative embodiments of the present disclosure include a zipper with the pull of the present disclosure as described above attached thereto.
- Alternative embodiments of the present disclosure include a product (such as but not limited to a backpack or other bag) with one or more zippers each with the pull of the present disclosure as described above attached thereto.
- Various changes and modifications to the present embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
