DETAILED DESCRIPTION OF THE INVENTION

[0023] The invention of a zipper lock as described throughout the present disclosure is best described with reference to the exemplary embodiments illustrated in the accompanying drawings. An illustrative embodiment with a single button for actuating the locking and unlocking of a zipper lock as described herein is shown in the various views presented in FIGS. 1-9. An alternative embodiment having two buttons for actuating the locking and unlocking of a zipper lock as described herein is illustrated in the views shown as FIGS. 10-18. Other embodiments are plausible, as will be recognized by one of ordinary skill in the art, each having general applicability to most bags or similar articles figured with zipper closures, and in particular zippers with two sliders that may be locked together using a device as described herein.

[0024] Turning now to the illustrative embodiments presented herein, FIG. 1 illustrates a top front isometric view of an embodiment A of a zipper lock as described and claimed herein in its locked position. As can be seen in FIG. 1, a zipper lock as described herein comprises two housings 101 that may be locked together and unlocked as described in further detail below. A carabiner 102 is attached to the top of each housing such that it is capable of rotating slightly inward (i.e., toward the opposite housing) when light pressure is applied to the outside of the carabiner 102 causing the carabiner 102 to rotate about an axis defined by a thin rod 103 spanning a thickness 110 of a housing 101 passing through a nut 104 into which the end of the carabiner 102 nearest the interface 111 between the two housings 102 is inserted.

[0025] FIG. 2 illustrates a top rear isometric view of the embodiment of FIG. 1 in its locked position. A button 201 connected to a deadbolt 202 is configured such that when the button 201 is depressed, the deadbolt 202 is depressed to enable unlocking of the housings 101 from one another.

[0026] Front and rear views of the embodiment of FIG. 1 in its locked position are illustrated in FIGS. 3 and 4, respectively, with the button 201 and deadbolt 202 set in the locked position as shown in FIG. 4. Left and right side views of the same are shown in FIGS. 5 and 6, respectively. Top and bottom views of the same are shown in FIGS. 7 and 8, respectively.

[0027] Turning to FIG. 9, a top front isometric view of the illustrative embodiment of FIG. 1 is shown in its open position to illustrate in further detail the function of the zipper lock according to FIG. 1. The housing 101 on the left side of the drawing comprises a cavity 901 into which a deadbolt 202 may be inserted when button 201 is depressed and the housings 101 are moved together at interface 111, then when button 201 is released, deadbolt 202 protrudes through a lock bore 902 on the rear face of the housing 101 on the left of the drawing.

[0028] An alternate embodiment of a zipper lock according to the present disclosure is illustrated in FIGS. 10-18, with FIG. 10 illustrating a top front isometric view of the embodiment B and FIG. 11 illustrating a top rear isometric view of the same, which is configured with two buttons, in its locked position. As can be seen in FIGS. 10 and 11, a zipper lock according to this embodiment comprises two housings 101 that may be locked together and unlocked as described in further detail below. A carabiner 102 is attached to the top of each housing such that it is capable of rotating slightly inward (i.e., toward the opposite housing) when light pressure is applied to the outside of the carabiner 102 causing the carabiner 102 to rotate about an axis defined by a thin rod 103 spanning a thickness 110 of a housing 101 passing through a nut 104 into which the end of the carabiner 102 nearest the interface 111 between the two housings 102 is inserted. In this embodiment, two buttons 201 each connected to a deadbolt 202 is configured such that when a button 201 is depressed, the corresponding deadbolt 202 is depressed to enable unlocking of the housings 101 from one another.

[0029] Front and rear views of embodiment B in its locked position are illustrated in FIGS. 12 and 13, respectively, with the button 201 and deadbolt 202 set in the locked position. Left and right side views of the same are shown in FIGS. 14 and 15, respectively. Top and bottom views of the same are shown in FIGS. 16 and 17, respectively.

[0030] Turning to FIG. 18, a top front isometric view of illustrative embodiment B is shown in its open position to illustrate in further detail the function of the zipper lock according to FIGS. 10 and 11. The housing 101 on the left side of the drawing comprises a cavity 901 into which a deadbolt 202 may be inserted when button 201 is depressed and the housings 101 are moved together at interface 111, then when button 201 is released, deadbolt 202 protrudes through a lock bore 902 on the rear face of the housing 101 on the left of the drawing. The same features and functionality, although not shown, are present on the reverse side of the view, with the button and deadbolt being configured on opposite housings, as one of ordinary skill in the art will appreciate when considering FIG. 18 in view of FIGS. 10 and 11.

[0031] It will be appreciated by one of ordinary skill in the art that while the illustrative embodiments of the drawings of the present disclosure show the faces of each housing being configured as a rectangle with a substantially semi-circular or rounded end, other configurations are possible.

[0032] For example, carabiners need not be used exclusively as the means for securing two zipper pulls together, or a single zipper pull to another part of a bag for locking. Not only that, but where carabiners are used, they need not be presented in a horseshoe shaped configuration as they are in the illustrative embodiments of the accompanying drawings, not do they need to rotate inward as described above. Rather, the nut described herein could be absent from alternative embodiments and each carabiner could rotate outward from a top surface of a housing to then be secured to a zipper pull and rotated back inward.

[0033] The housings illustrated in the drawings may take multiple shapes and need not be presented as rectangular with substantially rounded edges as they are in the illustrative embodiments of the drawings. Additionally, but buttons and deadbolts may be configured in different sizes and shapes, so long as they comprise a locking means securing the housings together once the one or more zipper pulls as described herein have been secured. Indeed, one of ordinary skill in the art could envision a configuration where a locking and unlocking means such as a button and deadbolt combination could appear on the side of each housing rather than the front or rear face. Additionally, the deadbolt could be replaced with a hook or clasp suitable for locking the housings together. These and other possible configurations will be readily appreciated by one of ordinary skill in the art.
