DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

FIGS. 4 and 5 illustrate front and rear views, respectively of a zipper slider assembly 60, according to an embodiment of the present invention. FIGS. 6 and 7 illustrate first and second lateral views, respectively, of the zipper slider assembly 60. FIGS. 8 and 9 illustrate top and bottom views, respectively, of the zipper slider assembly 60. The assembly 60 may be integrally formed or molded from a single piece of material, such as plastic or metal.

Referring to FIGS. 4-9, the assembly 60 includes a main body 62 having an upright beam 64 that connects to one end of a top horizontal beam 66 at a right angle. An opposite end of the top horizontal beam 66, in turn, connects to an end of another upright beam 68 at a right angle. As shown in FIG. 4, the beam 64 is longer than the beam 68.

Further, the beam 68 includes a stepped ledge 70 that extends into an open-ended passage 72 defined between the beams 64, 68 and the top beam 66. The stepped ledge 70, in turn, connects to another stepped ledge 74 that extends further into the passage 72. A protruding leg 76 extends below the ledge 74 and is generally parallel with the beam 64.

Planar walls 65, 67, and 69 extend perpendicularly from the beams 64, 66, and 68, respectively, as shown in FIGS. 6 and 7, in particular. The ledges 70, 74, and the leg 76 extend along the length of the wall 69. As such, the inner surface of the wall 69 is stepped into the passage 72, as defined by the ledges 70 and 74. The inner surface of the walls 65 and 67 may, however, be smooth and straight.

A securing loop 78 extends laterally outward from a side of the beam 64. A closed passage or eyelet 80 is defined within the securing loop 78.

Similarly, a securing loop 82 extends laterally outward from a side of the beam 68. A closed passage or eyelet 84 is defined within the securing loop 82.

As shown in FIGS. 4 and 5, in particular, the loops 78 and 82 are at a level that is approximately at the mid-level of the beam 68. That is, the loop 82 is generally centered at a level that bisects the beam 68. The loop 80 is aligned at the same level as the loop 82. It has been found that the placement of the loops 78 and 82 at this level provides for efficient pulling of the assembly 60 through cords (discussed below). That is, the placement of the loops 78 and 82 at this level allows a user to move the assembly 60 over a zipper using an amount of force with the least amount of wasted energy.

As noted, the securing loops 78 and 82 are aligned with one another at the same level (in relation to the center of the assembly 60) on opposite sides of the main body 62. The securing loops 78 and 82 are configured to securely and slidably retain cords within the closed passages 80 and 84, respectively.

The assembly 60 is configured to securely and slidably retain a zipper within the passage 72, as shown and described with respect to FIGS. 10-14. While the passage is shown with the ledges 70 and 74 extending therein, the assembly 60 maybe configured so that the wall 69 is similar to the wall 65, both in terms of length and interior contours. In general, the assembly 60 may be configured in various arrangements that allow a zipper to pass into an interior channel, and the opposing walls to exert compressive, squeezing forces into the zipper in order to close opposing track members.

As shown in FIG. 9, in particular, terminal interior edges 86 and 88 of the walls 65 and 69, respectively, may angle away from one another. Therefore, the openings at either end of the passage 72 may be wider than the remainder of the passage 72. The wider end openings 86, 88 are configured to more readily receive the zipper as it passes into the passage 72.

FIG. 10 illustrates an isometric lateral view of the zipper slider assembly 60 operatively connected to a zipper 90, according to an embodiment of the present invention. FIG. 11 illustrates an isometric front view of the zipper slider assembly 60 operatively connected to the zipper 90. FIG. 12 illustrates an isometric top view of the zipper slider assembly 60 operatively connected to the zipper 90. The zipper 90 includes opposing track members 92 and 94, similar to the zipper 10 shown and described with respect to FIGS. 1-3.

Referring to FIGS. 10-12, the main body 62 slidably receives the track members 92 and 94 within the passage 72 (hidden from view in FIG. 10). Referring to FIGS. 4-12, the stepped ledges 70 and 74 extending from interior surfaces of the wall 69 compress into reciprocal outer features of the track member 92, thereby squeezing the track member 92 into the track member 94. As the assembly 60 is slid in the direction of arrow B, the walls 65 and 69 compress the track members 92 and 94 together so that they securely fasten together. If the zipper slider assembly 60 is slid back in the direction of arrow B′, the slider assembly 60 may cause the track members 92 and 94 to separate from one another. However, the assembly 60 is generally configured to allow the zipper 90 to be closed in either directions denoted by arrows B and B′.

A cord 96 is slidably retained within the passage 84 (shown in FIG. 4) of the loop 82. Similarly, a cord 98 is slidably retained within the passage 80 of the loop 78 (shown in FIG. 4). Free ends of the cords 96 and 98 are compressively secured by opposing caps 100 and 102. Outer surfaces of the caps 100 and 102 may include grip ridges 104 that provide a tactile interface for a user to grasp. Optionally, a single cord may be looped through one cap, with both free ends being secured together in the other cap.

In operation, a user grasps the cap 102 to pull the zipper slider assembly 60 in the direction of arrow B. As the cap 102 is pulled in the direction of arrow B, the cords 96 and 98 slide through the loops 82 and 78, respectively, until the cap 100 abuts into the main body 62 of the assembly 60. As the cap 102 continues to be urged in the direction of arrow B, the resulting force exerted by the cap 100 into the main body 62 causes the zipper assembly to move over the zipper 90 in the direction of arrow B.

Conversely, the user grasps the cap 100 to pull the zipper slider assembly 60 in the direction of arrow B′. As the cap 100 is pulled in the direction of arrow B, the cords 96 and 98 slide through the loops 82 and 78, respectively, until the cap 102 abuts into the main body 62 of the assembly 60. As the cap 100 continues to be urged in the direction of arrow B′, the resulting force exerted by the cap 102 into the main body 62 causes the zipper assembly to move over the zipper 90 in the direction of arrow B′.

FIG. 13 illustrates a lateral view of the zipper slider assembly 60 operatively connected to the zipper 90, according to an embodiment of the present invention. FIG. 14 illustrates a top view of the zipper slider assembly 60 operatively connected to the zipper 90. Referring to FIGS. 13 and 14, when the cap 102 is pulled in the direction of arrow B such that the cap 100 abuts the main body 62 of the assembly 60, a bottom edge of the cap 100 abuts into the top wall 67 of the main body 62. With increased urging of the cap 102 in the direction of arrow B, the bottom edge of the cap 100 exerts a pushing force into the top wall 67 in the direction of arrow B, thereby causing the assembly 60 to move over the zipper 90 in the direction of arrow B.

The force exerted by the cap 100 into the main body 62 is in the direction of arrow C. Accordingly, the exerted force has a downward component in the direction of C_d and a horizontal component in the direction of C_h. The downward component C_d cancels any upward force exerted by a user pulling on the cap 102. As such, the likelihood of the slider assembly 60 being pulled off the zipper 90 is minimized. The horizontal component C_h forces the zipper slider assembly 60 to move in the direction of arrow B.

Because the loops 78 and 82 are aligned and on opposite sides of the main body 62, a squeezing force is created when the caps 100 or 102 are pulled. For example, as shown in FIG. 14, in particular, when the cap 102 is urged in the direction of arrow B, such that the cap 100 acts to push the zipper assembly 60 in the same direction, the cords 96 and 98 tighten with respect to the lateral walls of the assembly 60. In this manner, the taut cords 96 and 98 compressively squeeze the main body 62, thereby causing the main body 62 to compress and slidably secure the track members 92 and 94 together in order to close the zipper. Accordingly, instead of a user manipulating the track members 92 and 94 together between two fingers and subsequently sliding those fingers over the length of the zipper 90, the user simply pulls on the cap 102, which then operates to move the slider assembly 60 to close the zipper 90.

When the cap 100 is pulled in the opposite direction to move the zipper slider assembly 60 over the zipper 90 in the direction of arrow B′, the movements are reversed in a similar manner. For example, as the cap 100 is pulled in the direction of arrow B′, the bottom edge of the cap 102 abuts into the top wall 67 in a similar fashion. This movement may also be configured to close the zipper 90. Optionally, this movement may be configured to open the zipper 90. In either case, instead of a user grasping the zipper 90 itself, the user, instead, grasps the cap 100 and pulls in the direction of arrow B′, and the pulling movement causes the zipper slider assembly 60 to close or open the zipper 90.

Thus, embodiments of the present invention provide a zipper slider assembly that is configured to allow a user to easily and intuitively close and/or open a zipper. Use of the opposing cords on either side of the slider assembly to move the main body of the slider assembly over the opposing track members of the zipper decreases the amount of time needed to close the zipper. By allowing the cords to slide back and forth through the eyelets (i.e., closed passages) on either side of the main body, the slider assembly may easily be used in either longitudinal direction over the length of the zipper.

Unlike typical sliders, embodiments of the present invention provide a zipper slider assembly that is operable in both longitudinal directions over a zipper. That is, the zipper slider assembly 60 may be pulled in the direction of arrow B or arrow B′ in order to close the zipper 90. Further, embodiments of the present provide pull cords for ease of manipulation, as noted above.

The orientations may be inverted, rotated, or otherwise changed, such that an upper portion is a lower portion, and vice versa, horizontal becomes vertical, and the like.
