Abstract

An article of luggage having interlocking zipper pulls may include one or more opening lines having a zipper positioned along a perimeter of the opening line. Each zipper may include two zipper sliders with associated zipper tabs. At least one of the zipper tabs may include an engagement feature, and at least another of the zipper tabs may include an aperture sized to receive the engagement feature therethrough. The engagement feature may be positioned through the aperture in a zipper pull tab receptacle attached to a lock of the luggage item to secure both of the zipper pull tabs to the lock. In some luggage articles, four zipper tabs may be secured to the lock simultaneously using two zipper tab receptacles on the lock.

Description

Luggage with interlocking zipper pull tabs

This patent application is a divisional application of patent application No. 201510157682.1 entitled "luggage with interlocked zipper pull tabs" filed as "seoul IP stock limited liability company".

Technical Field

The present invention relates to luggage items, and more particularly to interlocking zipper pulls for luggage items.

Background

An item of luggage, in particular a luggage case (suitcase), defines an inner enclosed space. Often, the interior enclosure is accessed from the exterior of the case through the use of zippers. The zipper provides a convenient mechanism for accessing the interior of the luggage case, but also makes it relatively easy to gain unauthorized access to the items contained within the enclosure. To protect against such unauthorized access, various zipper locking systems for luggage have been developed to prevent the zipper from being operated by an unauthorized user.

A zipper locking system involves locking zipper sliders to each other. Examples of such systems are shown in U.S. patent nos. 4,395,891, 2005/0109072, 4,350,375 and chinese patent No. CN 201403621. In U.S.4,395,891 and U.S.2005/0109072, the zipper slider incorporates a locking device that allows the two zipper sliders to be secured to each other along a line of opening. However, this configuration is unsatisfactory in that the zipper slider is required to be larger than a conventional zipper slider. In addition, these systems have undesirably required highly specialized zipper sliders. In U.S.4,350,375, a lock plate is connected to one of the zipper tabs of the zipper and is configured to allow the lock plate to be connected to a protrusion of the other zipper tab. The result of this construction is that the locking plate attached to one zipper is unreasonably large and the protrusion on the other zipper pull tab presents a potential risk of injury to the user when the user grasps the pull tab to move the link slider. Moreover, such an arrangement is undesirably limited to locking zipper sliders located on the same line of opening together. In CN201403621, a conventional padlock is required to secure the zipper sliders to each other. This locking system is undesirable because the user needs to know the trajectory of the mortise lock when the padlock is not attached to the pull tab of the zipper slider. Additionally, if the user forgets where to place the padlock, the user cannot secure the zipper sliders to each other.

Another zipper locking system involves fixedly attaching a lock to the luggage case. In such systems, the zipper pulls are then secured to the lock to prevent the zipper sliders associated with the secured zipper pulls from being moved along their respective zipper tracks. Conventionally, zipper pulls are secured to a lock by providing each zipper pull with a slot in the lock. The end of the zipper pull tab that includes the hole or slot is then positioned within the slot and a pin, hook or the like received within the lock is positioned within the hole or slot of the zipper pull tab. Once the pin or hook is positioned within the hole or slot of the zipper pull tab, the pin or hook is prevented from moving out of the hole unless the user enters the correct combination or code on the lock or uses a key to unlock the lock. The lock and zipper pull tab are further configured such that the zipper pull tab cannot be removed from the slot in the lock prior to removing the pin or hook from the hole or slot in the zipper pull tab, thereby effectively securing the zipper pull tab to the lock. The detailed construction and operation of various types of such locking devices is described in more detail in the following patents and patent applications: U.S.5,557,954, U.S.6,807,832, EP 1914369 and WO 2008/34006.

One problem with this locking system is that each zipper pull tab secured to the lock requires a slot and a pin or hook. Thus, for example, when it is desired to simultaneously secure four zipper tabs to a lock, four slots and pins or hooks are required. In addition, as the number of tabs that are simultaneously secured increases, the complexity of the lock and the number of parts required for the lock also undesirably increase. In addition, the size of the lock must also be increased to accommodate the securing of all of the zipper tabs to the lock, which undesirably increases the weight of the lock. While this weight increase may seem less important, every item on the luggage case is unnecessarily heavier than necessary, which, in aggregate, increases the overall weight of the luggage case, thereby reducing the weight of items that a user can place in the luggage case in order to meet various important requirements (e.g., airline weight restrictions).

Accordingly, it is desirable to provide an improved luggage case, and more particularly, an improved zipper locking system for a luggage case that addresses the above-described problems and/or more generally provides an improvement or alternative to existing devices.

Detailed Description

Referring to fig. 1, one embodiment of an article of luggage, such as a luggage case 100, having interlocking zipper pull tabs includes a generally cuboidal structure formed by a plurality of walls that define an enclosed interior volume of the luggage case 100 in which the user's belongings are contained. The luggage piece 100 may include opposing front and

rear walls

102, 104 that form the front (front) and rear (back) of the luggage piece 100, opposing

side walls

106, 108 that form the sides of the luggage piece 100, and opposing top and

bottom end walls

110, 112 that form the top and bottom surfaces of the luggage piece 100. Together, these

walls

102, 104, 106, 108, 110, 112 define an exterior structure of the luggage piece 100, which in turn defines an enclosed interior volume.

The luggage 100 may be of the type commonly referred to as a soft shell luggage, wherein the outer structure is typically formed of a flexible material (e.g., fabric, etc.). These flexible materials may be supported by a frame and/or a plate to maintain the shape of the luggage piece 100. The frame may be formed using plastic, composite metal, metal or other structural material, while the panels may be generally formed using plastic such as polypropylene (PP) or Polyethylene (PE). Although shown as a soft shell luggage case, the luggage case 100 may also be of the type commonly referred to as a hard shell luggage case, wherein the exterior structure and walls of the case are relatively rigid. For hard-shell luggage, the exterior structure of the luggage 100 may be, for example, plastic (e.g., composite plastic, acrylonitrile butadiene styrene, polymer, thermoplastic, etc.) and manufactured by extrusion, molding, blow molding, etc. The luggage 100 may also be of a hybrid type, where features of a soft shell luggage and features of a hard shell luggage are combined to produce a luggage 100 that is hard in some areas and soft in other areas. Alternatively, the luggage case may also be a briefcase, computer bag or other similar case type having an opening secured by a zipper. Preferably, however, the luggage 100 is a zipper-closed suitcase.

The luggage piece 100 may be divided along a generally vertical plane having a first opening line 114 parallel to the major face. The luggage item 100 may include: a lid 116, the lid 116 comprising a front wall 102; and a base 118, the base 118 including the rear wall 104. In the embodiment shown in fig. 1, the first opening line 114 may be positioned closer to the rear wall than the front wall, such that the base 118 includes less than half of the

side walls

106, 108, top end wall 110, and bottom end wall 112 and the rear wall 104, while the lid 116 includes more than half of the

side walls

106, 108, top end wall 110, and bottom end wall 112 and the front wall 102. In other embodiments, the first line of openings 114 may be located at other desired locations, such as closer to the middle or closer to the front. When the first opening line 114 is positioned approximately midway, the base 118 includes the

side walls

106, 108, approximately one half of the top end wall 110 and the bottom end wall 112, and the back wall 104, while the lid 116 includes the

side walls

106, 108, approximately one half of the top end wall 110 and the bottom end wall 112, and the front wall 102. When the first line of opening 114 is positioned closer to the front, the lid 116 primarily includes the front wall 102, while the base 118 includes most of the

side walls

106, 108, top end wall 110 and bottom end wall 112, and the rear wall 104.

The luggage piece 100 may include a telescoping handle that may extend above the top end wall 110 of the luggage piece 100 to an extended position at a height that is convenient for a user to grasp. The telescoping handle may be used to pull, guide and rotate the luggage piece 100. In this embodiment of the luggage piece 100, the telescoping handle is oriented to have a grip portion that is parallel to the rear (back) of the luggage piece 100, where the user uses the handle to push or pull the luggage piece 100. In this embodiment, the telescoping handle extends from the luggage piece 100 in a telescoping manner adjacent the rear face (back face) at the center of the rear face (back face) of the luggage piece 100 and includes two parallel tubes interconnected at one top end by a gripping portion. The telescoping handle may be moved to a retracted position in which the telescoping handle does not extend substantially beyond the top end wall 110 of the luggage piece 100 and the gripping portion is substantially flush with the top end wall 110 and/or proximate to the top end wall 110. The luggage piece 100 may also include one or more stationary carrying handles to facilitate carrying or lifting of the luggage piece 100. The top stationary handle 120 may be located on the top end wall 110 as shown. Alternatively or additionally, one or more stationary handles may be located on the right side wall 108, the left side wall 106, and/or the bottom end wall 112 of the luggage piece 100.

The swivel wheel assembly 122 may be mounted to at least one of the walls, often the bottom end wall 112, near the bottom end of the luggage 100. Each swivel wheel assembly 122 may be positioned proximate a corner of the luggage piece 100. Each rotating wheel assembly 122 may include one or more rotating wheels 124, the one or more rotating wheels 124 rotatably mounted to a rotating fork carriage 126 for rotation about a wheel axis. The wheel axis may be generally horizontal and parallel to the bottom end wall 112 of the luggage piece 100, while the swivel fork bracket 126 may be rotatably mounted to the bottom end wall 112 of the luggage piece 100 to rotate about a generally vertical axis of rotation that is perpendicular to the bottom end wall 112 of the luggage piece 100. This arrangement allows the rotary wheel 124 to rotate about two orthogonal axes: a horizontal wheel axis and a vertical axis of rotation.

In an alternative embodiment, the rotating wheel assembly 122 may be replaced by a pair of fixed axis wheels that are each mounted near the rear wall 104 of the luggage piece 100. The fixed-axis wheels rotate about a common, generally horizontal fixed axis that is generally parallel to the rear wall 104. Each of the fixed-axis wheels may be located at a bottom corner of the luggage piece 100. In other words, each fixed axis wheel may be located near the bottom end and one of the

side walls

106, 108 of the luggage piece 100. The peripheral rim and edges of the fixed axis wheels protrude a predetermined distance beyond the bottom end wall 112 of the luggage piece 100 to allow the luggage piece 100 to be supported in an upright manner on the fixed axis wheels and on one or more feet extending from the bottom end of the luggage piece 100 near the front of the luggage piece 100 on the ground.

The lid 116 may be connected to the base 118 along the sidewalls via a hinge 128 in a conventional manner, and the luggage piece 100 may be opened at the first opening line 114 to access the interior volume. The hinge 128 may be formed from a strip of fabric with or without a zipper or in any other known manner. In some examples, the luggage piece 100 may be hinged along the left or

right side walls

106, 108, while in other examples, the luggage piece 100 may be hinged along the bottom of the luggage piece 100 or along any other face of the luggage piece 100. A first zipper 130 positioned along the perimeter of the first opening line 114 secures the lid 116 to the base 118 to open and close the luggage piece 100.

The luggage piece 100 may further include a pocket 132 to divide the enclosed interior of the luggage piece into smaller spaces. The bag 132 is accessible through the exterior surface of the luggage piece 110 via a second line of opening 134. The second opening line 134 may be selectively opened and closed using a second zipper 136 positioned along the second opening line 134.

Referring to fig. 2-4, the first and

second zippers

130 and 136 may include first and second zipper tracks 138 and 140, respectively. Each of first zipper track 138 and second zipper track 140 includes a pair of zipper strips having interlocking teeth that can be selectively interlocked using one or more zipper sliders (sliders) 142, 144. In the illustrated embodiment of the luggage piece 100, the first zipper 130 includes two first zipper sliders 142, and the second zipper 136 includes two second zipper sliders 144. In an alternative embodiment, the first zipper 130 and/or the second zipper 136 may include a single first zipper slider 142 and a single second zipper slider 144, respectively. For the first zipper 130, each first zipper slider 142 includes a first zipper pull tab 146 connected to the first zipper slider 142 to facilitate moving the first zipper slider 142 along the first zipper track 140. Similar to the first zipper 130, each second zipper slider 144 for the second zipper 136 includes a second zipper pull tab 148 connected to the second zipper slider 144 to facilitate moving the second zipper slider 144 along the second zipper runner 140.

For the first zipper 130, each first zipper pull tab 146 may include a body 150. The body 150 may be an elongate body having upper and lower surfaces 152 connected by a sidewall 154 of the body, the sidewall 154 extending between the upper and lower surfaces 152. The upper and lower surfaces 152 may be generally planar and parallel to each other as described in fig. 2, or take other forms, such as upper and lower surfaces 152 that are twisted or curved about the longitudinal axis of the body 150. The body 150 may include a length defined by the distance from the first zipper slider 142 to the free end 156 of the first zipper pull tab 146 and a width defined by the distance between the side walls 154 of the elongate body 150. The length may be greater than the width. This configuration for the bodies 150 provides a relatively easy-to-grasp object for a user when moving their respective first zipper sliders 142 along the first zipper track 138 using the first zipper tabs 146. At the free end of the body 150, the body 150 may optionally be curved to extend generally transversely relative to the longitudinal axis of the elongate body 150. Other configurations are possible so long as the body 150 provides an object for a user to grasp in order to move its respective first zipper slider 142 along the first opening line 114 using the first zipper pull tab 146.

Optionally, a slot 158 or the like may be formed in the body 150 of each first zipper pull tab 146 to reduce the weight of the first zipper pull tab 146. The slot 158 may extend substantially parallel to the length of the body 150, and the slot 158 may also pass through a slider loop 160 or the like on the first zipper slider 142 to connect the first zipper pull tab 146 to the corresponding first zipper slider 142.

Each first zipper pull tab 146 may further include an engagement feature 162 extending from the body 150. In some embodiments, the engagement feature may extend laterally from a planar lower surface of the body 150 and be substantially parallel to the sidewall 154 of the body 150. In other embodiments, the engagement feature 162 may extend laterally from the sidewall 154 of the body 150 and be generally parallel to at least one of the upper and lower surfaces 152 of the body 150. The engagement feature may define a lock opening 164 through which the lock opening 164 may receive a pin, hook, or the like attached to a lock 166 of the luggage piece 100 to secure the first zipper pull tab 146 to the lock 166.

The engagement feature may be a ring, a protrusion, or any other suitable structure. When the engagement feature 162 takes the form of a loop, the loop may be generally U-shaped, arcuate, or any other suitable shape, and is positioned proximate the free end 156 of the first zipper pull tab 146. The collar 162 may define the lock opening 164 either by itself or with the body 150.

The lock 166 may include a combination dial 168 and a key hole 170. The lock 166 may further include a zipper pull tab receptacle 172, the zipper pull tab receptacle 172 being defined in a housing 174 of the lock 166 and receiving at least a portion of the engagement feature 162 of the first zipper pull tab 146. The zipper pull tab receptacle may take the form of a slot, hole, or any other suitable structure capable of receiving at least a portion of the engagement feature 162.

In operation, once a sufficient portion of engagement feature 162 is positioned within zipper pull tab receptacle 172, a pin, hook, or the like received in housing 174 of lock 166 may be positioned through lock opening 164 to prevent removal of engagement feature 162 from zipper pull tab receptacle 172 and thereby secure first zipper pull tab 146 to lock 166. The lock 166 and the first zipper pull tab 146 are further configured such that the first zipper pull tab 146 cannot be removed from the zipper pull tab receptacle 172 in the lock 166 prior to removal of the pin, hook or the like from the lock opening 164, thus effectively securing the first zipper pull tab 146 to the lock 166. Further, once the pin, hook, or the like is positioned in the lock opening 164, the pin, hook, or the like is prevented from moving out of the lock opening 164 unless the user first enters the correct combination using the code dial 168 of the lock or unlocks the locking mechanism contained within the housing 174 of the lock 166 with a key inserted into the key hole 170.

There may be a zipper pull tab receptacle 172 for each first zipper pull tab 146 having an engagement feature 162. Thus, for the embodiment of the luggage piece 100 shown in fig. 1, the lock 166 includes two zipper pull tab receptacles 172 because there are two first zipper pull tabs 146 having engagement features 162. Each zipper pull tab receptacle 172 may include a pin, hook, or the like to secure the respective engagement feature 162 received with each zipper pull tab receptacle 172 to lock 166.

For the second zipper 136, each second zipper pull tab 148 may be substantially similar to the first zipper pull tab 146, except that each second zipper pull tab 148 does not include an engagement feature 162. Thus, each second zipper pull tab 148 may take the form of a body 176 (such as an elongated body) having an aperture 178 such as a slot or the like, the body 176. However, for each second zipper pull tab 148, the aperture 178 is sized large enough to receive the loop 162 of the first zipper pull tab 148 therethrough. In addition, the length of the

bodies

150, 176 of the first and

second zipper tabs

146, 148 are sized to be sufficiently long and the engagement feature 162 of the first zipper tab 146 and the aperture 178 of the second zipper tab 148 are located on their

respective bodies

150, 176 such that the engagement feature 162 extending from the body 150 of the first zipper tab 146 passes through the aperture 178 of the second zipper tab 148 when the first zipper tab 146 overlaps the second zipper tab 148. This allows each second zipper pull tab 148 to be secured to the lock 166 using a corresponding first zipper pull tab 146, since the second zipper pull tabs 148 essentially function as hasps.

Specifically, the second zipper pull tab 148 may be positioned between the lock 166 and its corresponding first zipper pull tab 146 such that the first zipper pull tab 146 overlaps the second zipper pull tab 148. The engagement feature 162 of the first zipper pull tab 146 may pass through an aperture 178 in the second zipper pull tab 148 into the zipper pull tab receptacle 172 of the lock 166 to secure the first zipper pull tab 146 to the lock 166. This in turn secures the second zipper pull tab 148 to the lock 166 because the engagement feature 162 cannot be removed from the aperture 178 of the second zipper pull tab 148 without first disengaging the first zipper pull tab 146 from the lock 166. An advantage of such a system is that both

zipper tabs

146, 148 can be secured to the lock 166 of the luggage 100 with a single zipper tab receptacle 172 fixedly attached into the lock 166. Thus, for the embodiment of the luggage 100 shown in fig. 1-4, four

zipper tabs

146, 148 may be simultaneously secured to the lock 166 using two zipper tab receptacles 172 on the lock 166, with two of the zipper tabs 146 associated with the first zipper slider 142 and two of the zipper tabs 148 associated with the second zipper slider 144.

Referring to fig. 4, the user can also secure only the first zipper pull tab 146 to the lock 146, if desired. Specifically, rather than passing the engagement feature 162 of the first zipper pull tab 146 through the aperture 178 of the second zipper pull tab 148, the engagement feature 162 of the first zipper pull tab may simply be inserted into the zipper pull tab receptacle 172 of the lock 166. This arrangement then secures the first zipper pull tab 146 to the lock 166 without also securing the associated second zipper pull tab 148 to the lock 166, thus allowing the user to secure only the first zipper pull tab 146 to the lock 166, as shown in FIG. 4.

While the first zipper pull tab 146 has been described and depicted as having the engagement feature 162 and the second zipper pull tab 148 has been described and depicted as having an aperture 178 sized to receive the engagement feature 162, any combination of the first zipper pull tab 146 and the second zipper pull tab 148 may have the engagement feature 162 and the aperture 178 sized to engage the feature 162 so long as there is a

zipper pull tab

146, 148 having the engagement feature 162 and another aperture 178 sized appropriately for each set of corresponding first and second

zipper pull tabs

146, 148. For example, both of the second zipper tabs 146 may have engagement features 162, while both of the first zipper tabs 146 may have an aperture 178, the aperture 178 being sized to receive the engagement features 162 therethrough. As another example, one first zipper pull tab 146 may have an engagement feature 162 while its corresponding second zipper pull tab 148 may have an appropriately sized aperture 178, and another first zipper pull tab 148 may have an appropriately sized aperture 178 while its corresponding second zipper pull tab 148 has an engagement feature 162.

Fig. 5 depicts another embodiment of an article of luggage, such as luggage 200, having interlocking zipper tabs. The second embodiment of the luggage piece 200 may be generally similar to the first embodiment of the luggage piece 100, except that the luggage piece 200 includes a central portion 290 that extends around the perimeter of the luggage piece along the top, bottom, left and right side walls and separates the lid 216 from the base 218. Additionally, in this second embodiment, a first opening line 214 is located between the central portion and the base portion 218 to secure the base portion 218 to the central portion 290 to open and close the luggage case 200, and a second opening line 234 is located between the central portion 290 and the lid 216 to secure the lid 216 to the central portion 290 to open and close the luggage case 200. Thus, in this second embodiment, each of the first opening line 214 and the second opening line 234 may be parallel to a major face of the luggage case 200 and divide the luggage case 200 along a generally vertical plane. Further, the first line of opening 214 divides the luggage case 200 between the base 218 and the middle 290 to allow access to the enclosed space within the luggage case 200, while the second line of opening 234 divides the luggage case 200 between the middle 290 and the lid 216 to also allow access to the enclosed space within the luggage case 200.

Similar to the first embodiment of the luggage piece 200, the second embodiment of the luggage piece 200 may include a first zipper 230 and a second zipper 236 associated with the first opening 214 and the second opening 234, respectively. For the second embodiment of the luggage case 200, the first and

second zippers

230 and 236 are substantially similar to the first and

second zippers

130 and 136 of the first embodiment of the luggage case 200 and operate in substantially the same manner. Thus, similar to the first embodiment of the luggage 200, the two zipper pulls 246, 248 for each of the first and

second zippers

230, 236 can be simultaneously secured to the lock 166 with a single zipper pull tab receptacle 172. Additionally, as with the first embodiment of the luggage 100, the lock 166 may include two zipper pull tab receivers 172 to simultaneously secure four

zipper pull tabs

246, 248 to the lock 166, with two zipper pull tabs 246 associated with the first zipper 230 and two other zipper pull tabs 248 associated with the second zipper 236.

Fig. 6 and 7 depict another embodiment of an article of luggage, such as luggage 300, having interlocking zipper tabs. In this embodiment, the luggage case 300 may be of a hard-shell construction. The luggage piece 300 includes a first zipper 330 associated with the first opening line 314 to secure the lid 316 of the luggage piece 300 to the base 318 of the luggage piece 300. The first zipper 330 may include two first zipper sliders 342. Each zipper slider 342 may include an associated

zipper pull tab

346a, 346b, and

zipper pull tabs

346a, 346b may be referred to as a first zipper pull tab 346a and a second zipper pull tab 346 b. Each

zipper pull tab

346a, 346b may comprise a generally elongate body 350, which body 350 is bent about an associated first zipper slider 342 of the

zipper pull tabs

346a, 346b such that the first zipper pull tab 346a may overlap a second zipper pull tab 346b when the first zipper sliders 342 are positioned next to each other. Additionally, similar to the previously described embodiments, the first zipper pull tab 346a may include an engagement feature 362, the engagement feature 362 may define a lock opening 364, the lock opening 364 may be received within a zipper pull tab receptacle 372 of the lock 366, and the second zipper pull tab 346b may include an aperture 378 sized to receive the engagement feature 362 therethrough. Thus, in this embodiment, a single zipper pull tab receptacle 372 is used to connect both

zipper pull tabs

346a, 346b associated with first zipper 330 to lock 366.

More specifically, second zipper pull tab 346b may be positioned between first zipper pull tabs 346 a. As described above for the previous embodiments, the engagement feature 362 may then be passed through the aperture 378 in the second zipper pull tab 346b and positioned in the zipper pull tab receptacle 372 of the lock 366 to secure the first zipper pull tab 346a to the lock 366, which in turn secures the second zipper pull tab 346b to the lock 366. Securing

zipper tabs

346a, 346b to lock 366 prevents associated first zipper slider 342 from moving along first opening line 314. Additionally, as with the first and second embodiments of the luggage 100, both of the zipper pulls 346a, 346b remain secured to the lock 366 until the first zipper pull 346a is disengaged from the lock 366.
