Detailed Description

[0042] Various apparatuses or processes will be described below to provide an example of each claimed embodiment. No embodiment described below limits any claimed embodiment and any claimed embodiment may cover processes or apparatuses that differ from those described below. The claimed embodiments are not limited to apparatuses or processes having all of the features of any one apparatus or process described below or to features common to multiple or all of the apparatuses described below.

[0043] Referring to Figure. 1 A, illustrated therein is a front view of an anti-theft bag 100 in a closed configuration according to one embodiment. Anti-theft bag 100 is shown in Figures 1A-11. Anti-theft bag 100 includes body 102 comprising a first surface 104 and a main compartment which is disposed behind first surface 104. The main compartment includes an extended neck 106 through which items can be placed into the main compartment.

[0044] The first surface 104 has a first engagement member 108 of a locking mechanism disposed thereon. In the embodiment of Figures 1 A-11, the first engagement member 108 is an opening within the material of the first surface 104. The opening 108 is surrounded by a frame 110 which provides strength and reinforcement to the opening 108. The frame may be composed of metal or another strong material which prevents damage to the opening whether that damage be normal wear and tear or intentional damage. The frame 110 also acts to limit the size of opening 108 as the frame 110.

[0045] In other embodiments the opening may be reinforced by anti-cut materials or by other means of secure reinforcement.

[0046] In the embodiment of Figures 1A-11, the anti-theft bag 100 comprises a first pocket behind the first surface wherein opening 108 provides access to the first pocket through the first surface and wherein the first pocket has an opening at the top (relative to the top of the bag 100). In the embodiment of Figures 1A-11 the first pocket is on the front of the bag 100. The main compartment is behind the first pocket. In some embodiment the main compartment is directly behind the first pocket, in other embodiment there may be additional compartments between the first pocket and the main compartment.

[0047] The anti-theft bag 100 of Figure 1A also comprises a strap including a first strap portion 112 and a second strap portion 114. The first strap portion 112 and the second strap portion 114 can be reversibly connected by a strap buckle 116 and the length of strap may be adjusted by feeding more or less of the second strap portion 114 through an adjustment member 118. When the first strap portion 112 and the second strap portion 114 are connected by strap buckle 116 a user can use the strap to wear the anti-theft bag on their person. Figure 2 shows wherein the strap can be used to engage the anti-theft bag to a fixed object to prevent theft (discussed below).

[0048] In Figure 1A, anti-theft bag 100 is in an open configuration. Figure 1 B shows a front view of anti-theft bag 100 in a closed configuration.

[0049] The extended neck 106 of the main compartment is foldable towards the first surface 104. On an outer surface of the extended neck 106 is disposed a second engagement member 120 of the locking mechanism such that when the extended neck 106 is folded over towards the first surface 104, the second engagement member 120 is at the front of bag 100. In Figure 1A, the second engagement member is positioned at the rear of the bag because the extended neck 106 has not been folded. Folded extended neck 106 is inserted into the first pocket of bag 100 such that folded extended neck 106 is positioned behind the first surface 104. The second engagement member 120 is inserted through opening 108 of the first surface 104.

[0050] In the embodiment of Figures 1 A-11, the second engagement member 120 is a loop buckle which is inserted through the opening 108. In the embodiment of bag 100, the loop buckle, including a u-shaped ring (loop) and a base plate, comprises one solid piece of metal. In other embodiments, the loop buckle may comprise a hinge attaching a loop to a base plate. However, unless the hinge is impossible to remove, a loop buckle with no hinge is preferred as the hinge may be vulnerable to wear and tear or could be exploited by a person hoping to steal contents of the bag. In yet other embodiment, the loop buckle may comprise any solid and secure piece of material, or two pieces of metal or other secure materials that are riveted together or secured by other means of bonding together.

[0051] Figure 1 C is a front view of an anti-theft bag 100 in a closed and locked configuration according to one embodiment. To secure the bag 100 in a closed configuration wherein the main compartment is inaccessible a locking member 124 is engaged with the locking mechanism 122 (locking mechanism 122 comprises the first engagement member 108 as called out in Figures 1A and 1 B and the second engagement member 120 as called out in Figure 1 B). In the embodiment of Figures 1 A-11, wherein the first engagement member is an opening and the second engagement member is a loop buckle, the locking member 124 is inserted through the loop buckle to prevent the loop buckle from being un-inserted through the opening and allowing the main compartment to be accessed. In Figure 1 C the locking member 124 is a padlock.

[0052] In other embodiments, the locking member 124 may be any type of lock or other means which engages with a first engagement member and a second engagement member to enable the user to control when the bag is accessible or inaccessible.

[0053] In other embodiments, the first engagement member and the second engagement member may reversibly lock together without a locking member.

[0054] In other embodiments, the locking mechanism may not be an opening and loop buckle system but the locking mechanism may still require a locking member to reversibly lock the locking mechanism. [0055] In all embodiments, when the bag is reversibly locked either by directly locking the first engagement member to the second engagement member or by indirectly locking the first engagement member to the second engagement member with a locking member, the contents of the main compartment of the bag cannot be removed without the permission of the user/owner of the bag.

[0056] When the first engagement member is an opening, the opening is sized to not allow the locking member to pass through the opening. When the opening has a frame, the frame is sized to not allow the locking member to pass through the opening.

[0057] At least some of the material of the anti-theft bag 100 may be anti-cut material. In particular, the material of the main compartment, including the extended neck, and the material of the first pocket (in embodiments with a first pocket) would preferably be made of an anti-cut material to prevent access to the main compartment either directly or by cutting the first surface to release the second engagement member from the first engagement member by widening the opening.

[0058] Figure 1 D is a rear view of an anti-theft bag 100 in an open configuration according to one embodiment. The rear view of anti-theft bag 100 in an open configuration shows the location of the second engagement member 120 on the extended neck 106 of the main compartment. The first strap portion 112, second strap portion 114, strap buckle 116, and adjustment member 118 are also shown.

[0059] Anti-theft bag 100 has a rear pocket 126 which is accessible even when the locking mechanism is engaged. In Figure 1 D, the rear pocket 126 has a zipper which closes the pocket and a flap which folds down to cover the zipper. In other embodiments, the rear pocket may close by other means of closure, e.g., a flap which engages with magnets to securely close, or may be open at the top.

[0060] Figure 1 E is a rear view of an anti-theft bag 100 in a closed configuration according to one embodiment. In Figure 1 E, the extended neck 106 of the main compartment has been folded down towards the first surface on the front of the bag 100. The extended neck 106 may be inserted into the first pocket as shown in Figure 1 B and may be locked with a locking member as shown in Figure 1 C. [0061] Figure 1 F is a bottom view of an anti-theft bag 100 according to one embodiment. The main compartment of the bag 100 has a bottom 128. The bottom 128 of bag 100 is expandable to increase the volume of the main compartment to allow more objects to be placed within the main compartment. Two bottom straps 130 are disposed on the bottom 128. In other embodiments, there may be more or less straps. The bottom straps 130 are operable to control expansion of the bottom 128 of the main compartment. The bottom straps may also be operable to hold an item between the straps and the bottom of the bag, e.g., an umbrella, a coat, a tripod, etc. In anti-theft bag 100, each bottom strap 130 comprises a material connected to a hook mechanism which is engageable to a loop disposed across a width of the bottom 128 of the main compartment. When the hook is engaged to the loop the bottom 128 is not expanded. When the hook is disengaged from the loop the bottom 128 can be expanded. Additionally, each strap 130 may be adjustable in length to allow for expansion of the bottom 128 of the bag or to securely hold an item, as described above, between the bottom 128 and the bottom straps 130.

[0062] In other embodiments, the bottom straps may comprise two pieces connect by a bottom strap buckle wherein disconnecting the bottom strap buckle allows the expansion of the bottom 128.

[0063] In other embodiments, the bottom of the bag is flat (either rigid or soft) and the main compartment is not expandable. In such an embodiment, there may or may not be bottom straps. In such an embodiment, bottom straps may still be used to hold an item, e.g., an umbrella, a coat, a tripod, at the bottom of the bag.

[0064] Figure 1 G is a bottom view of an anti-theft bag 100 according to one embodiment. The view of Figure 1 G provides more context for the location of the strap components relative to the other elements of the bag 100. In figure 1 G, the strap is at the rear of the bag 100 (the side opposite the first surface). The first strap portion 112 and the second strap portion 114 are connected by the strap buckle 116. The view of Figure 1 G shows the engagement of the second strap portion 114 with the adjustment member 118. A length of the second strap portion 114 can be adjusted by feeding more or less of the second strap portion 114 through the adjustment member. The second strap portion 114 includes a grommet 132 as a strap engagement member for engaging with the locking mechanism of the bag 100 (either directly or indirectly through a locking member) when securing the bag 100 to a fixed object. Figure 2 shows wherein the strap can be used to engage the anti-theft bag to a fixed object to prevent theft (discussed below). In other embodiments there may be more than one grommet on the second strap portion for engaging with the locking mechanism.

[0065] In other embodiments, the strap engagement member may comprise other means to engage the strap with the locking mechanism. For example, the strap may include a loop which can engage with the locking mechanism (or a locking member).

[0066] In other embodiments the strap may comprise a single strap portion which attaches to an attachment member on the bag. For example, a first part of the strap buckle may be directly attached to the anti-theft bag instead of to a second strap portion.

[0067] Figure 1 H is a side view of an anti-theft bag 100 in an open configuration according to one embodiment. The front of the anti-theft bag 100 is on the left side of Figure 1 H and the rear is on the right. The bag 100 is in an open configuration with the extended neck 106 in an unfolded position wherein the second engagement member 120 (loop buckle 120) is at the rear of the bag 100. The first strap portion 112 is shown as well as one bottom strap 130. The bottom strap 130 controls the ability to expand the main compartment.

[0068] The side view of anti-theft bag 100 shows a side surface 134 of the main compartment. The side view of anti-theft bag also shows the first pocket 136 wherein the first surface 104 is an outer front surface of the first pocket 136.

[0069] Figure 11 is a side view of an anti-theft bag 100 in a closed configuration according to one embodiment. Figure 11 shows the extended neck 106 of the main compartment in a folded configuration wherein the extended neck 106 has been folded over towards the front of the bag 100 and inserted into the first pocket 136. Second engagement member 120 (loop buckle 120) is inserted through the first engagement member (the opening) on the first surface of the first pocket 136. A locking mechanism (not shown) could be inserted through loop buckle 120 to prevent access to the main compartment (labelled as side surface 134). Again, one bottom strap 130 of the main compartment is shown.

[0070] Figure 2 is a top sectional view of an anti-theft bag 200 in a closed and locked configuration with a strap engaged to a locking mechanism of the anti-theft bag according to one embodiment. Anti-theft bag 200 is similar to anti-theft bag 100 of Figures 1A-11. Anti-theft bag 200 includes a first pocket 236, a main compartment 238, and a strap comprising a first strap portion 212 and a second strap portion 214.

[0071] The first pocket 236 includes a first surface 204 at the front (bottom of Figure 2) of the bag 200. The first pocket includes a first engagement member 208, which is an opening 208 through first surface 204 into first pocket 236.

[0072] The main compartment 238 includes an extended neck 206 with a second engagement member 220, which is a loop buckle 220. In Figure 2, the extended neck 206 has been folded over and inserted into first pocket 236 and the loop buckle 220 has been inserted through opening 208. The sectional view of Figure 2 provides a view where the top of the bag (the extended neck 206 that is folded over at the top of the bag) is not shown to allow for a view into the main compartment 238 and the first pocket 236 when the bag is in a closed configuration.

[0073] The anti-theft bag 200 is locked in the closed configuration by a padlock 224. In the embodiment of Figure 2 the padlock 224 is a combination padlock. In other embodiments a padlock may use a physical key, or a locking member other than a padlock may be employed.

[0074] The anti-theft bag 200 includes the first strap portion 212 and the second strap portion 214. The first strap portion 212 and the second strap portion 214 are connectable by a strap buckle 216. In Figure 2 the strap buckle 216 is shown in a disconnected configuration. A length of the second strap portion 214 is adjustable at an adjustment member 218 disposed on the second strap portion 214.

[0075] Second strap portion 214 further comprises a grommet 232 (as a strap engagement member) which is engaged with the padlock 224. When the second strap portion 214 is engaged with the padlock a loop is created by the body of the bag (components of the bag not including the strap) and the second strap portion 214. In use, the second strap portion 214 may be wrapped around a fixed object before the second strap portion 214 is engaged with the locking mechanism (opening 208 and loop buckle 220) and the padlock 224. The fixed object may be any object which is completely immobile or would be difficult to move by someone trying to steal the bag. For example, the fixed object may be a picnic table or a lamppost. The material of the strap may comprise an anti-cut material so that someone trying to steal the bag cannot merely cut the strap to remove the bag from the fixed object.

[0076] In the embodiment of Figure 2, the grommet 232 is directly engaged with the padlock 224. In other embodiments, the grommet may be directly engaged with the loop buckle wherein the grommet is inserted over the loop buckle and then the padlock 224 passes through the loop buckle. That is, the padlock may not pass through the grommet but only through the loop buckle.

[0077] In other embodiments, the second strap portion may comprise multiple grommets which enable the user to choose a size of the loop to better fit around the fixed object.

[0078] In some embodiments, the strap may include locking carabiners which enable the strap to engage with the locking mechanism or to engage with a fixed object. The locking carabiners require a plurality of steps to open and therefore are a deterrent to theft.

[0079] Figure 3A is a top sectional view of an anti-theft bag 300 according to one embodiment. Figures 3A and 3B are sectional views of the anti-theft bag 300 which show the various compartments and pockets in one embodiment of an anti-theft bag. Figure 3B is similar to the sectional view of Figure 2 but does not show a second engagement member, a locking member, an extended neck, or any elements of a strap. Only elements directly related to compartments and pockets are called out to reduce clutter.

[0080] Anti-theft bag 300 comprises a main compartment 338, a first pocket 336, a rear pocket 326, and an accessible outer pocket 340. [0081] The main compartment 338 is accessible through an extended neck when the bag is in an open configuration and is inaccessible when the bag is in a closed and locked configuration. The extended neck is a hollow neck that is an extension of the main compartment 338 and objects must pass through the hollow neck to enter the main compartment 338. In other embodiments, the extended neck may include a flap which is not hollow at the top of the extended neck such that the flap folds over to block the opening to the main compartment on the extended neck and further prevent access to the main compartment.

[0082] The first pocket 336 is on the front of the bag 300. In the embodiments of Figures 1 A-11, 2, and 3A, the first pocket receives the folded extended neck such that a first engagement member 308 (108 in Figures 1 A-11 and 208 in Figure 2) and a second engagement member (120 in Figures 1A-11 and 220 in Figure 2) can be engaged and a locking member can lock the bag to prevent access to the main compartment 338. In other embodiments, the extended neck may not be inserted into the first pocket 336 but the first pocket 336 may still be used to store other items.

[0083] In other embodiments the extended neck may fold over onto the outer surface (first surface 104 of Figures 1 A-11). In such an embodiment, the first engagement member of a locking mechanism which is disposed on the first surface of the bag may be a loop buckle and the second engagement member of the locking mechanism disposed on the extended neck may be an opening (shown in Figures 4A, 4B, 5A, and 5B and discussed below).

[0084] In all embodiments, the first pocket 336 is not accessible when the bag is in a closed and locked configuration.

[0085] The rear pocket 326 is on the rear of bag 300. In some embodiments the rear pocket 326 has a flap at the top which folds down to close the pocket. At least a first magnet in the flap may engage with at least a second magnet in an outside wall of the pocket. In other embodiments the rear pocket 326 may close by other means of closure, e.g., a zipper, or may be open at the top. The rear pocket 326 is accessible when the bag 300 is in an open configuration, a closed configuration, or a locked configuration, but may not be accessible when the bag is attached to a fixed object depending on the orientation of the rear relative to the fixed object.

[0086] The accessible outer pocket 340 is between main compartment 338 and first pocket 336. The accessible outer pocket 340 is accessible from a side of bag 300 and not from the top like first pocket 336 or rear pocket 326. The accessible outer pocket 340 is accessible is all configurations. The accessible outer pocket 340 is designed to hold objects which require convenient access such as an umbrella or a water bottle but may hold any object of an appropriate size. The accessible outer pocket 340 may have a means to ensure that objects do not fall out of the pocket, for example, the strap of the bag may be adjustable to block the opening, or the opening may be cinchable by a drawstring. The accessible outer pocket may have a bottom (on the side of the bag relative to the first pocket 336 (being the front) and the rear pocket 326 (being the rear) which is made of mesh gusset.

[0087] Each of the above compartments or pockets may include further interior pockets or compartments.

[0088] Figure 3b is a side sectional view of an anti-theft bag 300 according to one embodiment. Figure 3b shows a side view of the compartments and pockets discussed for Figure 3A: the main compartment 338, the first pocket 336, the rear pocket 326, and the accessible outer pocket 340. Figure 3b provides more context to the locations of the pockets as location of the extendable neck with the second engagement member 320 (loop buckle 320) is also shown.

[0089] Main compartment 338 is accessible through the extended neck, and is position directly between accessible outer pocket 340 (including first engagement member 308) and rear pocket 326, while accessible outer pocket 340 is between the first pocket 336 and the main compartment 338.

[0090] Within main compartment 338 is an interior pocket 342. This interior pocket may comprise radio-frequency identification (RFID) blocking material in the walls to prevent access to an RFID device such as a smartphone or car keys. [0091] Figures 4A-7 are isometric views of different embodiments of an anti-theft bag. While Figures 4A-7, all show sling-type bags, it is to be understood that any type of bag which could employ an anti-theft locking mechanism as discussed herein is contemplated. For example, a backpack, a messenger bag, or a satchel could apply the same anti-theft system.

[0092] Figure 4A is a front isometric view of an anti-theft bag 400 in a closed configuration with a strap engaged to a locking mechanism of the anti-theft bag according to another embodiment. Figure 4B is a front isometric view of an anti-theft bag 400 in an open configuration according to the embodiment of Figure 4A.

The locking mechanism comprises a first engagement member disposed on the first surface and a second engagement member disposed on the extended neck.

[0121] At 802 of method 800, the extended neck is folded over towards the first surface. The extended neck may be a hollow neck which is an extension of the main compartment and through which objects can be placed into the main compartment.

[0122] In other embodiments, the extended neck may have more than one portion wherein the first portion is a hollow neck through which objects can be placed into the main compartment and the second portion (which is further from the main compartment than the first portion) may be a flap.

[0123] In some embodiments the extended neck may be folded over only once. In other embodiments the extended neck may be folded over twice or more. In some embodiments the extended neck may include a zipper or other means of closure which close the extended neck to prevent access to the main compartment. The method 800 may further include closing the extended neck before folding the extended neck. [0124] At 804 of method 800, the first engagement member and the second engagement member are engaged to prevent access to the main compartment of the bag. If the extended neck is not folded over then the first engagement member and the second engagement member cannot be engaged. When the first engagement member and the second engagement member are engaged the bag is in a closed configuration wherein the main compartment is inaccessible.

[0125] The first engagement member and the second engagement member of the locking mechanism may be reversibly locked to maintain the bag in the closed configuration until such time as the locking mechanism is unlocked. In some embodiments, the first engagement member and the second engagement member may be lockable together without any additional members. In some embodiments, the first engagement member and the second engagement member require a locking member to reversibly lock the locking mechanism (e.g., a padlock) and the method 800 may further include engaging the locking member with the locking mechanism.

[0126] In some embodiments the first engagement member on the first surface is an opening and the second engagement member on the extended neck is a loop buckle and engaging the first engagement member with the second engagement member may further include inserting the loop buckle through the opening.

[0127] In some embodiments the first engagement member on the first surface is a loop buckle and the second engagement member on the extended neck is an opening and engaging the first engagement member with the second engagement member may further include inserting the loop buckle through the opening.

[0128] In embodiments with an opening and a loop buckle, a locking member (e.g., a padlock) may be introduced through the loop buckle to prevent the loop buckle from uninserting through the opening.

[0129] In some embodiments, the bag may include a strap having a first strap portion wherein the first strap portion is operable to wrap around a fixed object and engage with the locking mechanism to secure the bag to the fixed object. The method 800 may further include wrapping the first strap portion around a fixed object and engaging the first strap portion with the locking mechanism. The fixed object may be any object which is completely immobile or would be difficult to move by someone trying to steal the bag. For example, the fixed object may be a picnic table or a lamppost.

[0130] If the strap is connected to the bag when the user wishes to secure the bag to the fixed object, the method 800 may further include disconnecting the first strap portion from the bag.

[0131] In some embodiments, the strap may comprise a second strap portion wherein the first strap portion and the second strap portion are connected by a strap buckle. In those embodiments the method 800 may further comprise opening the strap buckle to disconnect the first strap portion from the second strap portion.

[0132] In some embodiments, the first strap portion may engage with the locking mechanism through a grommet disposed on the first strap portion. The method 800 may further include engaging the grommet with the locking mechanism.

[0133] The first strap portion may include multiple grommets to enable adjustment of a length of the first strap portion and ensure a better fit around a fixed object. In other embodiments the first strap portion may include an adjustment member which allows the user to adjust the length of the first strap portion to ensure a better fit for the user while carrying the bag or to ensure a better fit around a fixed object. The first strap portion may both be adjustable and have multiple grommets. The method 800 may further include adjusting a length of the first strap portion.
