Description

TECHNICAL FIELD

[0001] Embodiments of the present invention relate to soft-and hard-sided carrying cases, such as those used for luggage, and, more particularly, certain embodiments relate to a multi-stage handle assembly used, e.g., for carrying or directing such a case.BACKGROUND

[0002] Hard-sided and soft-sided cases for storing and / or transporting various types of equipment and luggage are known. The AIR line of cases from Pelican Products, Inc., of Torrance, California is one example of a hard-sided equipment or luggage case. Such cases typically employ a handle that is movable between a retracted position, at which the handle is adjacent the body of the case, and an extended position, at which the handle is spaced apart from the case. A latch or detent mechanism typically is provided to retain the handle in the retracted position and in the extended position. The user may disengage the latch or detent mechanism with one of her hands, but the user must use her other hand to push or pull the handle to move the handle between the retracted and extended positions.SUMMARY

[0003] In accordance with one embodiment, the present invention provides a handle assembly for use with a carrying case. The handle assembly comprises an elongate body having a longitudinal axis, a first side, and an opposite second side. The elongate body defines a first opening and a second opening disposed along the longitudinal axis. The first opening defines a handle portion. The handle assembly also comprises a release member coupled with the first side of the elongate body. The release member defines a first projection disposed within the first opening and a second projection disposed within the second opening. Also, the handle assembly comprises a panel disposed on the second side of the elongate body. The panel defines a panel body and a third projection. The third projection faces the elongate body. The elongate body is movable relative to the panel between a first position, at which the third projection is disposed within the first opening, and a second position, at which the third projection is disposed within the second opening. When the elongate body is in the first position, movement of the release member relative to the elongate body causes the first projection of the release member to translate within the first opening into engagement with the third projection of the panel to move the third projection out of the first opening. When the elongate body is in the second position, movement of the release member relative to the elongate body causes the second projection of the release member to translate within the second opening into engagement with the third projection of the panel to move the third projection out of the second opening.

[0004] In accordance with another embodiment, the present invention provides a handle assembly for use with a carrying case. The handle assembly comprises an elongate body having a proximal end and a distal end. The elongate body defines a handle portion at the distal end and further defines a plurality of apertures spaced along its length. Also, the handle assembly comprises a release member comprising a plurality of projections. The release member is coupled with the elongate body in a first position, wherein each projection of the plurality of projections is disposed within a respective aperture of the elongate body. Further, the handle assembly comprises a panel coupled with the elongate body. The panel defines a panel body and a latch member. The latch member is in selective engagement with an individual aperture of the plurality of apertures. The release member is movable relative to the elongate body from the first position to a second position, in which one of the projections of the plurality of projections interferes with the latch member in the individual aperture and moves the latch member out of engagement therewith.

[0005] In accordance with another embodiment, the present invention provides a handle assembly for use with a carrying case. The handle assembly comprises an elongate body having a proximal end and a distal end and defining a plurality of apertures. A handle portion is coupled with the elongate body distal end. Further, the handle assembly comprises a release member coupled with the elongate body. The release member defines a plurality of release member projections, wherein each release member projection of the plurality of release member projections is disposed within a respective aperture of the elongate body. The release member is movable relative to the elongate body between a first position and a second position. The handle assembly further comprises a panel coupled with the elongate body. The panel defines a panel body and a panel projection, wherein each individual aperture of the plurality of apertures is sized to receive the panel projection therein. When the release member is in the first position, the panel projection is insertable within one of the apertures of the plurality of apertures. When the release member is in the second position, the plurality of release member projections block insertion of the panel projection into the plurality of apertures and the elongate body is movable relative to the panel.

[0006] In accordance with a further embodiment, the present invention provides a method of operating a carrying case. The method comprises providing a handle assembly coupled with the carrying case. The handle assembly comprises an elongate body having a longitudinal axis, the elongate body defining a first opening, a second opening, and a third opening disposed along the longitudinal axis. The handle assembly also comprises a handle coupled with the elongate body and a release member coupled with the elongate body. The release member comprises a first projection disposed within the first opening, a second projection disposed within the second opening, and a third projection disposed within the third opening. Further, the handle assembly comprises a panel disposed on the elongate body. The panel has a panel body and a panel projection. The panel projection initially is disposed within the first opening. The method also comprises lifting the release member relative to the elongate body causing the first projection of the release member to move the panel projection out of the first opening and lifting the elongate body relative to the panel such that the first opening moves past the panel projection. Moreover, the method comprises further lifting the elongate body relative to the panel such that the second opening moves past the panel projection. Also, the method comprises lowering the release member relative to the elongate body. Finally, the method comprises further lifting the elongate body relative to the panel until the panel projection engages with the third opening.

[0007] In some embodiments of the method, one or more of the first, second, and third openings comprises a notch. In some embodiments, the method also comprises lifting the release member relative to the elongate body causing the third projection of the release member to move the panel projection out of the third opening. Further, some embodiments of the method comprise lowering the elongate body relative to the panel such that the third opening moves past the panel projection, lowering the release member relative to the elongate body, and lowering the elongate body relative to the panel until the panel projection engages with the second opening.

[0008] In yet another embodiment, the present invention provides a method of operating a handle assembly. The handle assembly comprises an elongate body defining a plurality of apertures spaced along the length thereof, a release member coupled with the elongate body and comprising a plurality of projections, wherein each projection of the plurality of projections is disposed within a respective aperture of the elongate body, and a panel coupled with the elongate body, the panel having a panel body and a latch member sized for selective engagement with each aperture of the plurality of apertures. The method comprises lifting the release member and the plurality of projections relative to the elongate body causing the latch member to move out of engagement with a first aperture of the plurality of apertures. Further, the method comprises moving the elongate body relative to the panel to position a second aperture of the plurality of apertures proximate the panel latch member. Also, the method comprises lowering the release member and the plurality of projections relative to the elongate body causing the latch member to move into engagement with the second aperture of the plurality of apertures.

The phrase “one of A and B” is satisfied by A, whether or not also in the presence of B, and by B, whether or not also in the presence of A.

[0035] Embodiments of the present invention relate to improved carrying cases, handle assemblies, and methods of using and operating such carrying cases and handle assemblies. In this regard, FIG. 1 illustrates an example carrying case 10 comprising a body 12 having a lower shell 14 and a lid 16 that together define an interior volume for stowing various types of equipment, luggage, or the like. Lid 16, which may be hingedly connected to lower shell 14, is movable relative thereto to access the interior volume. One or more latches 18 are provided in this embodiment to allow a user to maintain lid 16 in a closed position on lower shell 14. Two or more wheels 20 also can be provided. Here, case 10 is provided with a handle assembly 22 which is extendable and retractable relative to lower shell 14. When retracted, a user can carry case 10 via handle assembly 22 and / or pull, push, or otherwise direct case 10 on wheels 20, as is well understood. Case 10 also can be provided with one or more additional handles 24 in various embodiments. Although any suitable soft or hard material may be used for cases described herein, in one embodiment case 10 is formed from a suitable rigid plastic material, such as molded polypropylene, a copolymer thereof, or another suitable blend of plastic materials.

[0036] One embodiment of a handle assembly in accordance with the present invention will be described with reference to FIGS. 2-8. In these Figures, a handle assembly 100 is shown coupled with a lower shell 102 of a carrying case. Other components of the carrying case, which are well understood by those of skill in the art, are not shown. In general, handle assembly 100 comprises an elongate body 104, a release member 106, and a panel 108. However, panel 108 is not shown in FIGS. 3-4 in order to facilitate illustration of certain components of handle assembly 100. In various embodiments, any of elongate body 104, release member 106, and panel 108 can be formed from the same material as that of lower shell 102 or another rigid but lightweight material, such as aluminum or stainless steel, suitable for use in the intended application of the carrying case to which handle assembly 100 is attached.

[0037] In this embodiment, the release member 106 is coupled with elongate body 104 on an interior side (e.g., that facing lower shell 102) of elongate body 104 and panel 108 is coupled with elongate body 104 on an exterior side of elongate body 104. The opposite could be true in other embodiments. Also, while not required in all embodiments, here lower shell 102 defines a rectangular recess 112 dimensioned to receive handle assembly 100 therein, such that when handle assembly 100 is attached to lower shell 102, panel 108 is flush with an exterior surface of lower shell 102. Handle assembly 100 can be coupled with lower shell 102 at least in part via suitable fasteners extending through corresponding apertures 110 defined in panel 108 and lower shell 102. As described in greater detail below, in various embodiments, elongate body 104 and release member 106 are movable relative to panel 108 and thus may be only indirectly coupled with lower shell 102, e.g., via panel 108. Thus, in other words, elongate body 104 and release member 106 need not be independently or separately attached to lower shell 102.

[0038] Elongate body 104, which in this embodiment is generally rectangular in shape, defines a plurality of openings or apertures that each can have the same size or different sizes and / or shapes. As shown, for example, elongate body 104 defines a first opening 114 that defines a handle portion 116. Elongate body 104 also defines a second opening 118, a third opening 120, and a fourth opening 122. A greater or fewer number of openings can be provided in other embodiments. Openings 114, 118, 120, and 122 preferably are aligned with one another and are spaced apart from one another along the length of elongate body 104. As described in more detail below, each opening can define or correspond to a stop position (in extension or retraction) of elongate body 104. First opening 114 can define or correspond to a first position, second opening 118 can define or correspond to a second position, third opening 120 can define or correspond to a third position, and fourth opening 122 can define or correspond to a fourth position.

[0039] Release member 106 is coupled with elongate body 104 and movable relative thereto at least between a first, or lowered, position (FIG. 3) and a second, or raised, position (FIG. 4). In various embodiments, release member 106 can be biased into the lowered position, but this is not required in all embodiments. Release member 106 also defines a flange 124 that can be grasped by a user's fingers to urge release member 106 upwardly relative to elongate body 104 (e.g., against the bias) toward the raised position. In particular, release member 106 and flange 124 can be dimensioned such that a user grasping handle portion 116 with one hand can engage flange 124 with his or her fingers on the same hand.

[0040] Additionally, release member 106 in this embodiment defines a plurality of projections. The number, size, and shape of projections can vary in various embodiments, but in one embodiment, the number of projections on release member 106 corresponds to the number of openings 114, 118, 120, and 122, and this number likewise corresponds to the number of different positions to which the elongate body 104 can be moved. In general, the projections are disposed on release member 106 such that they are each at least partially disposed within a corresponding opening defined in elongate body 104. In the illustrated embodiment, release member 106 defines a first projection 126 disposed in first opening 114, a second projection 128 disposed in second opening 118, a third projection 130 disposed in third opening 120, and a fourth projection 132 disposed in fourth opening 122. As best seen in FIGS. 3-4, when release member 106 is moved from the lowered position to the raised position, each projection 126, 128, 130, and 132 translates upwardly within its respective opening 114, 118, 120, and 122.

[0041] Panel 108 preferably defines at least one latch member 134 (examples of which are shown in FIGS. 2, 5, 17, and 20) that is selectively engageable with an individual opening 114, 118, 120, or 122 when the release member 106 is disposed in the lowered position. In some embodiments, the at least one latch member 134 comprises one projection or multiple discrete projections that are in selective engagement with one of the openings 114, 118, 120, and / or 122. Latch member 134 can be biased toward elongate body 104 or, e.g., into a position of engagement with each opening 114, 118, 120, or 122. Thus, when the latch member 134, or a component thereof, is received in any of openings 114, 118, 120, and 122, the elongate body 104 is prevented from movement relative to panel 108.

[0042] However, when release member 106 is moved to the raised position, the projection 126, 128, 130, or 132 that corresponds to the opening 114, 118, 120, or 122 in which the latch member 134 is received at that time will translate into engagement with the latch member 134 (or component thereof) to move it out of the corresponding opening 114, 118, 120, or 122. If release member 106 is moved back to the lowered position, the latch member 134 will reenter the corresponding opening 114, 118, 120, or 122. But as long as release member 106 is maintained in the raised position, elongate body 104 is movable relative to the panel 108 without the latch member 134 engaging any of the openings 114, 118, 120, or 122. This allows elongate body 104 to be moved relative to panel 108 to any desired position.

[0043] As elongate body 104 is moved upwardly or downwardly relative to panel 108, latch member 134 will no longer be in alignment with one of the openings 114, 118, 120, and / or 122, and it may instead be in sliding engagement with a portion of elongate body 104 in which no opening is defined. When latch member 134 and elongate body 104 are in this configuration, release member 106 can be moved to the lowered position and elongate body 104 will remain moveable relative to panel 108 until latch member 134 comes into engagement with another one of the openings 114, 118, 120, and / or 122.

[0044] Once elongate body 104 is disposed at or near its desired position (e.g., a desired height above lower shell 102 or a desired amount of extension or retraction), release member 106 can be moved to its lowered position (if it is not in that position already). At that time, if latch member 134 is aligned with (e.g., disposed opposite) one of the openings 114, 118, 120, or 122, it will enter (e.g., be biased into engagement with) such opening and thereby “lock” elongate body 104 into that position. If latch member 134 is not aligned with one of the openings, then it will instead remain in sliding engagement with a portion of elongate body 104. As will be appreciated, latch member 134 can have various sizes and shapes in various embodiments, and its dimensions may vary as needed or desired to accommodate the dimensions of each opening 114, 118, 120, and / or 122.

[0045] FIGS. 2 and 5-8 show movement (e.g., extension) of elongate body 104 of handle assembly 100 to and between various positions relative to panel 108 and / or lower shell 102. In FIG. 2, elongate body 104 is in a first position, which may be a fully retracted position. Here, release member 106 is in a lowered position and latch member 134 is disposed within first opening 110. To move elongate body 104 to a deployed or extended position, a user can lift release member 106 to the raised position, as shown in FIG. 5. Here, first projection 126 engages and / or interferes with latch member 134, pushing latch member 134 out of first opening 110. As a result, latch member 134 no longer interferes with movement of elongate body 104, and elongate body 104 can be moved upwardly relative to panel 108 and lower shell 102. After the user does so, she can return release member 106 to its lowered position and continue to raise elongate body 104 relative to panel 108. This is shown in FIG. 6. Latch member 134 will slide along elongate body 104 until latch member 134 encounters second opening 118. If the user retains release member 106 in the raised position while lifting upward on elongate body 104, second projection 128 will block second opening 118 and / or prevent latch member 134 from entering, such that the user can continue lifting elongate body 104 upwardly past that second opening 118 and / or the second position, for instance to the third position shown in FIG. 7. However, if the user has returned release member 106 to its lowered position as described above, elongate body 104 will stop at the second position once the user raises elongate body 104 to a position where latch member 134 can move into engagement with second opening 118. Similar actuation of release member 106 and upward movement of elongate body 104 relative to panel 108 allows the user to move elongate body 104 to the third position, in which latch member 134 is disposed within third opening 120, as shown in FIG. 7, and to the fourth position, in which latch member 134 is disposed within fourth opening 122, as shown in FIG. 8. The latter may be a fully extended or fully deployed position of elongate body 104.

[0046] To return elongate body 104 to the retracted position, the user can move release member 106 to the raised position, causing projection 132 to engage and / or interfere with latch member 134 to push latch member 134 out of fourth opening 122, and then begin to lower elongate body 104 relative to panel 108. By maintaining release member 106 in the raised position, the user can continue to move elongate body 104 downwardly, such that latch member 134 does not engage either third opening 120 or second opening 118 as they move past. The user can then move release member 106 to the lowered position and continue to lower or retract elongate body 104 until latch member 134 again engages first opening 114.

[0047] Additional aspects of a handle assembly 200 in accordance with an embodiment of the present invention are described with reference to FIGS. 9-20. In general, handle assembly 200 comprises an elongate body 204, a release member 206, and a panel 208. Elongate body 204 has a first side 210 and an opposite second side 212. Elongate body 204 further defines a first opening 214 and comprises a handle portion 216. Elongate body 204 also includes second, third, and fourth openings 218, 220, and 222. Release member 206 defines a flange 224 and projections 226, 228, 230, and 232. Panel 208 defines a latch member 234.

[0048] FIGS. 9-12 depict certain operations of the elongate body 204 and release member 206 of handle assembly 200 wherein the panel 208 is not shown. FIGS. 13-14 show elongate body 204, FIGS. 15-16 show release member 206, and FIGS. 17-18 show panel 208. FIGS. 19-20 are exploded views of handle assembly 200.

[0049] In this embodiment, release member is coupled with the first side 210 of elongate body 204. For example, in various embodiments, release member 206 preferably defines at least one opening, and elongate body 204 preferably defines at least one projection disposed at least partially within the at least one opening when the release member 206 is coupled with elongate body 204. With reference to FIGS. 9-16, release member 206 defines three openings or slots 236, 238, and 240. Correspondingly, elongate body includes three projections 242, 244, and 246 disposed on first side 210. When release member 206 is disposed against elongate body 204, projections 242, 244, and 246 align with slots 236, 238, and 240. Of course, in other embodiments, additional or fewer slots and projections, of various shapes, could be provided.

[0050] Each projection 242, 244, and 246 comprises a flange 248 in this embodiment. Each flange 248 could be formed as a unitary part of each projection in some embodiments, but in this embodiment flanges 248 are separate components attached to each projection 242, 244, and 246 via a suitable fastener (e.g., a screw) 250 receivable in an aperture (e.g., a threaded hole) defined in each projection. As release member 206 moves between a lowered position (FIG. 9) and a raised position (FIG. 10), each respective slot 236, 238, and 240 translates about each flange 248 and respective projection 242, 244, and 246. Further, as best seen in FIGS. 9-10, flanges 248 have a first lateral dimension that is greater than a second lateral dimension of each respective slot 236, 238, and 240. As a result, release member 206 is slidably or movably coupled with elongate body 204.

[0051] Also, in certain embodiments, at least one spring is located between release member 206 and elongate body 204 to bias release member 206 toward the first or lowered position. With reference to FIGS. 13, 16, 19, and 20, for example, elongate body 204 defines a pair of channels 252 which in this embodiment resemble a half-cylinder and are disposed at the end of elongate body opposite handle portion 216. These example channels 252 are open at their respective lower ends and terminate in a rounded wall 254 at their respective upper ends. Correspondingly, release member 206 defines a pair of channels 256 which also resemble a half-cylinder and are disposed at the end of release member 206 opposite flange 224. These example channels 256 are open at their respective upper ends and terminate in a rounded wall 258 at their respective lower ends. Rounded walls 254 are dimensioned to translate within channels 256, and rounded walls 258 are dimensioned to translate within channels 252, and channels 252 and 256 together can form a substantially cylindrical volume. As shown in FIGS. 20-21, when release member 206 is coupled with elongate body 204, a pair of springs 260 (e.g., helical compression springs) are disposed in the volume defined by channels 252 and 256, with one end of each spring in engagement with a wall 258 and the opposite end of each spring in engagement with a wall 254. As release member 206 moves between a lowered position (FIG. 9) and a raised position (FIG. 10), each respective spring 260 is compressed between walls 258 and 254. In the lowered position of release member 206, each respective spring 260 is uncompressed. As a result, release member 206 is biased toward the lowered position.

[0052] As shown in FIGS. 13-14, elongate body 204 in this embodiment is generally rectangular in shape and defines a proximal end 259, a distal end 261, and a longitudinal axis 262 (FIG. 14). Handle portion 216 is disposed at distal end 261 in this embodiment. As noted above, elongate body 204 in this embodiment defines openings or apertures 214, 218, 220, and 222. Openings 214, 218, 220, and 222 are disposed along longitudinal axis 262 in this embodiment. Correspondingly, as shown in FIGS. 15-16, release member 206 also is generally rectangular in shape in this example and has a longitudinal axis that is aligned with longitudinal axis 262 when release member 206 is coupled with elongate body 204. When handle assembly 200 is assembled, movement of release member 206 between the lowered position and the raised position causes movement of projections 226, 228, 230, and 232 within the respective openings 214, 218, 220, and 222 along longitudinal axis 262. Although these openings each may have different shapes and sizes, in this embodiment they are each centered on longitudinal axis 262 in this example. The relative positions and spacing of openings 214, 218, 220, and 222 can vary, as needed or desired, to define stop positions in various locations.

[0053] In various embodiments described herein, each of the openings of a given elongate body 104, 204 preferably is sized to receive both a corresponding projection of a given release member 106, 206 and, selectively, the at least one latch member 134, 234 defined on a given panel 108, 208, or a component (such as one or more projections) thereof. As those of skill in the art will appreciate, the shape and / or dimensions of each such opening can vary in various embodiments, as needed or desired, while still accomplishing this purpose.

[0054] One example is shown in FIGS. 11-14 and 20. In this embodiment, each opening 214, 218, 220, and 222 comprises a generally rectangular lower portion 264, 266, 268, and 270 (FIG. 14) sized to receive a respective release member 206 projection 226, 228, 230, and 232. Each such lower portion is disposed beneath and connected to a generally rectangular upper portion 272, 276, 278, and 280 (FIG. 14) into which each respective projection 226, 228, 230, and 232 translates in response to movement of release member 206 from the lowered to the raised position. In this particular embodiment, the lateral dimension of lower portions 266 and 268 are the same as the lateral dimension of respective upper portions 276 and 278, while the lateral dimensions of lower portions 264 and 270 are smaller than the lateral dimensions of respective upper portions 272 and 280, but the lateral dimensions can vary in other embodiments. As seen in FIG. 14, lower portions 264, 266, 268, and 270 and upper portions 272, 276, 278, and 280 extend along longitudinal axis 262.

[0055] Also as explained herein, a latch member 234 of panel 208 (or a component thereof, such as one or more projections 296) is configured to selectively engage each opening 214, 218, 220, and 222. In the case of first opening 214, upper portion 272 defines a shoulder 282. When release member 206 is disposed in its lowered position and the at least one projection 296 of panel 208 is disposed in first opening 214, the at least one panel 208 projection 296 will be disposed on or above shoulder 282 (and above first projection 226 of release member 206). Thus, in this position, interference between shoulder 282 and the at least one projection 296 will prevent upward movement of elongate body 204.

[0056] In the case of second, third, and fourth openings 218, 220, and 222, each such opening defines laterally opposed notches 284, in each case disposed just above the respective lower portions 266, 268, and 270. In each such opening, the respective laterally opposed notches 284 together can define a slot sized to receive the at least one panel 208 projection 296 therein. Again, as seen in FIG. 14, the portions of openings 218, 220, and 222 that are defined by notches 284 extend along a transverse axis 285.

[0057] Thus, when release member 206 is disposed in its lowered position and the at least one projection 296 of panel 208 is disposed in second opening 218, the at least one panel 208 projection 296 will be disposed in the slot defined by notches 284 (and above second projection 228 of release member 206). Interference between the projection 296 and the slot defined by notches 284 will prevent upward or downward movement of elongate body 204. Engagement between projection 296 and the slots defined in each of openings 220 and 222 is similar to that described above.

[0058] FIGS. 17-18 are perspective views of an example embodiment of panel 208, which can be a portion of an exterior shell of a carrying case. As shown in FIGS. 19-20, panel 208 is disposed on the second side 212 of elongate body 204. In the illustrated embodiment, panel 208 defines a body portion 286 and a tongue portion 288. Tongue portion 288 can be defined in body portion 286 by a pair of parallel slots 290 and can extend between a proximal end 292 and a distal end 294. In various embodiments, tongue portion 288 is curved relative to body portion 286, e.g., in a direction facing the carrying case or handle assembly components to which panel 208 will be attached. In some handle assembly 200 embodiments, the distal end 294 of tongue portion 288 is biased toward or into engagement with the elongate body 204. Tongue portion 288 thus can be flexible and bendable away from its biased position, e.g., in response to interference with a projection of release member 206.

[0059] As noted above, panel 208 includes latch member 234. In this embodiment, latch member 234 comprises tongue portion 288 and a projection 296 at or proximate distal end 294 of tongue portion 288. Projection 296, which can be at least one lip or flange or the like in various embodiments, faces the elongate body 204 in handle assembly 200. As discussed above, projection 296 is dimensioned to selectively engage slots formed by the notches 284 in openings 218, 220, and 222. Correspondingly, the latch member 234 of panel 208 is configured to engage with one or more projections of release member 206, such as projections 226, 228, 230, and 232 shown in FIGS. 15-16. In this embodiment, projections 226, 228, 230, and 232 are generally boxlike in shape, with generally rectangular lower surfaces and flat sides. However, on the sides of projections 226, 228, 230, and 232 that face panel 208 in handle assembly 200, the sides can transition from a flat surface 297 to a rounded upper surface 298 and to an angled surface 300. While the shapes and contours can vary in various embodiments, it will be appreciated that the shapes of projections 226, 228, 230, and 232 are configured, during engagement between the projections 226, 228, 230, and 232 and the projection 296, to translate upward movement of release member 206 into movement of latch member 234 out of engagement with elongate body 204. In some embodiments, projections 226, 228, 230, and 232 define a cam surface configured to engage with the at least one projection 296, which acts as a follower.

[0060] Of course, various embodiments of the present invention can include one or more latch members that are different than latch members 134, 234 shown herein, and in some embodiments the latch members need not be disposed on a panel 108, 208 at all. For example, in some embodiments, a latch member analogous to latch member 234 could be on side 210 of elongate body 204 and release member 206 could be on side 212 of elongate body 204. Additionally, one or more projections or other latch members could be coupled with or part of a carrying case's exterior shell (e.g., lower shell 102) in some embodiments.

[0061] Other variations are possible and within the scope of the present invention. For instance, in various embodiments, either or both of elongate body 204 and / or release member 206 could be provided in multiple pieces, rather than as single unitary components. As such, other embodiments could include more than one elongate body 204 and / or more than one release member 206. Likewise, the various openings and projections discussed above could have different numbers, shapes, and / or dimensions while performing the same or similar functions to those described herein. Finally, although one or more preferred embodiments have been discussed herein in the context of a hard-sided case for carrying equipment, luggage, or the like, those of skill in the art will appreciate that the present invention is not so limited. In particular, it is contemplated that embodiments of the present invention may be used with a variety of types of cases, including both hard-and soft-sided cases used for any purpose.

[0062] Based on the foregoing, it will be appreciated that embodiments of the invention provide improved equipment cases, multi-stage handle assemblies, and methods of operating carrying cases and handle assemblies. Among other things, in embodiments of the present invention, a carrying case can be provided with a handle assembly that is extendable and retractable in multiple stages, e.g., it can be moved relative to the carrying case to various predefined stop positions. Thus, such a carrying case can have a handle that is adjustable to accommodate both taller and shorter users, as opposed to a handle that extends only to a single position. In various embodiments, a person can operate such a handle assembly using only one hand (e.g., the hand that is already grasping the handle). Also as described herein, embodiments of the handle assembly have a low profile, robust construction, and do not require the use of any buttons.

[0063] Many modifications and other embodiments of the inventions set forth herein will come to mind to one skilled in the art to which these inventions pertain having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the inventions are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Moreover, although the foregoing descriptions and the associated drawings describe exemplary embodiments in the context of certain exemplary combinations of elements and / or functions, it should be appreciated that different combinations of elements and / or functions may be provided by alternative embodiments without departing from the scope of the appended claims. In this regard, for example, different combinations of elements and / or functions than those explicitly described above are also contemplated as may be set forth in some of the appended claims. In cases where advantages, benefits or solutions to problems are described herein, it should be appreciated that such advantages, benefits and / or solutions may be applicable to some example embodiments, but not necessarily all example embodiments. Thus, any advantages, benefits or solutions described herein should not be thought of as being critical, required or essential to all embodiments or to that which is claimed herein. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.

TECHNICAL FIELD

[0001] Embodiments of the present invention relate to soft-and hard-sided carrying cases, such as those used for luggage, and, more particularly, certain embodiments relate to a multi-stage handle assembly used, e.g., for carrying or directing such a case.BACKGROUND

[0002] Hard-sided and soft-sided cases for storing and / or transporting various types of equipment and luggage are known. The AIR line of cases from Pelican Products, Inc., of Torrance, California is one example of a hard-sided equipment or luggage case. Such cases typically employ a handle that is movable between a retracted position, at which the handle is adjacent the body of the case, and an extended position, at which the handle is spaced apart from the case. A latch or detent mechanism typically is provided to retain the handle in the retracted position and in the extended position. The user may disengage the latch or detent mechanism with one of her hands, but the user must use her other hand to push or pull the handle to move the handle between the retracted and extended positions.SUMMARY

[0003] In accordance with one embodiment, the present invention provides a handle assembly for use with a carrying case. The handle assembly comprises an elongate body having a longitudinal axis, a first side, and an opposite second side. The elongate body defines a first opening and a second opening disposed along the longitudinal axis. The first opening defines a handle portion. The handle assembly also comprises a release member coupled with the first side of the elongate body. The release member defines a first projection disposed within the first opening and a second projection disposed within the second opening. Also, the handle assembly comprises a panel disposed on the second side of the elongate body. The panel defines a panel body and a third projection. The third projection faces the elongate body. The elongate body is movable relative to the panel between a first position, at which the third projection is disposed within the first opening, and a second position, at which the third projection is disposed within the second opening. When the elongate body is in the first position, movement of the release member relative to the elongate body causes the first projection of the release member to translate within the first opening into engagement with the third projection of the panel to move the third projection out of the first opening. When the elongate body is in the second position, movement of the release member relative to the elongate body causes the second projection of the release member to translate within the second opening into engagement with the third projection of the panel to move the third projection out of the second opening.

[0004] In accordance with another embodiment, the present invention provides a handle assembly for use with a carrying case. The handle assembly comprises an elongate body having a proximal end and a distal end. The elongate body defines a handle portion at the distal end and further defines a plurality of apertures spaced along its length. Also, the handle assembly comprises a release member comprising a plurality of projections. The release member is coupled with the elongate body in a first position, wherein each projection of the plurality of projections is disposed within a respective aperture of the elongate body. Further, the handle assembly comprises a panel coupled with the elongate body. The panel defines a panel body and a latch member. The latch member is in selective engagement with an individual aperture of the plurality of apertures. The release member is movable relative to the elongate body from the first position to a second position, in which one of the projections of the plurality of projections interferes with the latch member in the individual aperture and moves the latch member out of engagement therewith.

[0005] In accordance with another embodiment, the present invention provides a handle assembly for use with a carrying case. The handle assembly comprises an elongate body having a proximal end and a distal end and defining a plurality of apertures. A handle portion is coupled with the elongate body distal end. Further, the handle assembly comprises a release member coupled with the elongate body. The release member defines a plurality of release member projections, wherein each release member projection of the plurality of release member projections is disposed within a respective aperture of the elongate body. The release member is movable relative to the elongate body between a first position and a second position. The handle assembly further comprises a panel coupled with the elongate body. The panel defines a panel body and a panel projection, wherein each individual aperture of the plurality of apertures is sized to receive the panel projection therein. When the release member is in the first position, the panel projection is insertable within one of the apertures of the plurality of apertures. When the release member is in the second position, the plurality of release member projections block insertion of the panel projection into the plurality of apertures and the elongate body is movable relative to the panel.

[0006] In accordance with a further embodiment, the present invention provides a method of operating a carrying case. The method comprises providing a handle assembly coupled with the carrying case. The handle assembly comprises an elongate body having a longitudinal axis, the elongate body defining a first opening, a second opening, and a third opening disposed along the longitudinal axis. The handle assembly also comprises a handle coupled with the elongate body and a release member coupled with the elongate body. The release member comprises a first projection disposed within the first opening, a second projection disposed within the second opening, and a third projection disposed within the third opening. Further, the handle assembly comprises a panel disposed on the elongate body. The panel has a panel body and a panel projection. The panel projection initially is disposed within the first opening. The method also comprises lifting the release member relative to the elongate body causing the first projection of the release member to move the panel projection out of the first opening and lifting the elongate body relative to the panel such that the first opening moves past the panel projection. Moreover, the method comprises further lifting the elongate body relative to the panel such that the second opening moves past the panel projection. Also, the method comprises lowering the release member relative to the elongate body. Finally, the method comprises further lifting the elongate body relative to the panel until the panel projection engages with the third opening.

[0007] In some embodiments of the method, one or more of the first, second, and third openings comprises a notch. In some embodiments, the method also comprises lifting the release member relative to the elongate body causing the third projection of the release member to move the panel projection out of the third opening. Further, some embodiments of the method comprise lowering the elongate body relative to the panel such that the third opening moves past the panel projection, lowering the release member relative to the elongate body, and lowering the elongate body relative to the panel until the panel projection engages with the second opening.

[0008] In yet another embodiment, the present invention provides a method of operating a handle assembly. The handle assembly comprises an elongate body defining a plurality of apertures spaced along the length thereof, a release member coupled with the elongate body and comprising a plurality of projections, wherein each projection of the plurality of projections is disposed within a respective aperture of the elongate body, and a panel coupled with the elongate body, the panel having a panel body and a latch member sized for selective engagement with each aperture of the plurality of apertures. The method comprises lifting the release member and the plurality of projections relative to the elongate body causing the latch member to move out of engagement with a first aperture of the plurality of apertures. Further, the method comprises moving the elongate body relative to the panel to position a second aperture of the plurality of apertures proximate the panel latch member. Also, the method comprises lowering the release member and the plurality of projections relative to the elongate body causing the latch member to move into engagement with the second aperture of the plurality of apertures.

[0009] In accordance with a further embodiment, the present invention provides a method of operating a handle assembly. The handle assembly comprises an elongate body defining a plurality of apertures, a release member coupled with the elongate body, the release member defining a plurality of release member projections, wherein each release member projection of the plurality of release member projections is disposed within a respective aperture of the elongate body, and a panel coupled with the elongate body, the panel defining a panel body and a panel projection, wherein each individual aperture of the plurality of apertures is sized to receive the panel projection therein. The method comprises positioning the release member and the plurality of release member projections relative to the elongate body in a first position allowing the panel projection to engage one of the apertures of the plurality of apertures. Additionally, the method comprises positioning the release member and the plurality of release member projections relative to the elongate body in a second position preventing the panel projection from engaging any of the apertures of the plurality of apertures. Further, the method comprises moving the elongate body relative to the panel.BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Reference will now be made in detail to presently preferred embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that modifications and variations can be made in the present invention without departing from the scope or spirit thereof. For instance, features illustrated or described as part of one embodiment may be used on another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

[0033] As used herein, terms referring to a direction or a position relative to the orientation of a case, handle assembly, or components thereof, such as but not limited to “vertical,”“horizontal,”“upper,”“lower,”“front,” or “rear,” refer to directions and relative positions with respect to the case's, handle assembly's, or component's orientation in its normal intended operation, as indicated in the Figures herein. Thus, for instance, the terms “vertical” and “upper” refer to the vertical direction and relative upper position in the perspectives of the Figures and should be understood in that context, even with respect to an apparatus that may be disposed in a different orientation. The term “substantially,” as used herein, should be interpreted as “nearly” or “close to”, such as to account for design and manufacturing tolerances of the apparatus.

[0034] Moreover, the term “or” as used in this application and the appended claims is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from the context, the phrase “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, the phrase “X employs A or B” is satisfied by any of the following instances: X employs A; X employs B; or X employs both A and B. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from the context to be directed to a singular form. Throughout the specification and claims, the following terms take at least the meanings explicitly associated herein, unless the context dictates otherwise. The meanings identified below do not necessarily limit the terms, but merely provide illustrative examples for the terms. The meaning of “a,”“an,” and “the” may include plural references, and the meaning of “in” may include “in” and “on.” The phrase “in one embodiment,” as used herein does not necessarily refer to the same embodiment, although it may. The phrase “at least one of A and B” is satisfied by any of A alone, B alone, A and B alone, and A and B with others. The phrase “one of A and B” is satisfied by A, whether or not also in the presence of B, and by B, whether or not also in the presence of A.

[0035] Embodiments of the present invention relate to improved carrying cases, handle assemblies, and methods of using and operating such carrying cases and handle assemblies. In this regard, FIG. 1 illustrates an example carrying case 10 comprising a body 12 having a lower shell 14 and a lid 16 that together define an interior volume for stowing various types of equipment, luggage, or the like. Lid 16, which may be hingedly connected to lower shell 14, is movable relative thereto to access the interior volume. One or more latches 18 are provided in this embodiment to allow a user to maintain lid 16 in a closed position on lower shell 14. Two or more wheels 20 also can be provided. Here, case 10 is provided with a handle assembly 22 which is extendable and retractable relative to lower shell 14. When retracted, a user can carry case 10 via handle assembly 22 and / or pull, push, or otherwise direct case 10 on wheels 20, as is well understood. Case 10 also can be provided with one or more additional handles 24 in various embodiments. Although any suitable soft or hard material may be used for cases described herein, in one embodiment case 10 is formed from a suitable rigid plastic material, such as molded polypropylene, a copolymer thereof, or another suitable blend of plastic materials.

[0036] One embodiment of a handle assembly in accordance with the present invention will be described with reference to FIGS. 2-8. In these Figures, a handle assembly 100 is shown coupled with a lower shell 102 of a carrying case. Other components of the carrying case, which are well understood by those of skill in the art, are not shown. In general, handle assembly 100 comprises an elongate body 104, a release member 106, and a panel 108. However, panel 108 is not shown in FIGS. 3-4 in order to facilitate illustration of certain components of handle assembly 100. In various embodiments, any of elongate body 104, release member 106, and panel 108 can be formed from the same material as that of lower shell 102 or another rigid but lightweight material, such as aluminum or stainless steel, suitable for use in the intended application of the carrying case to which handle assembly 100 is attached.

[0037] In this embodiment, the release member 106 is coupled with elongate body 104 on an interior side (e.g., that facing lower shell 102) of elongate body 104 and panel 108 is coupled with elongate body 104 on an exterior side of elongate body 104. The opposite could be true in other embodiments. Also, while not required in all embodiments, here lower shell 102 defines a rectangular recess 112 dimensioned to receive handle assembly 100 therein, such that when handle assembly 100 is attached to lower shell 102, panel 108 is flush with an exterior surface of lower shell 102. Handle assembly 100 can be coupled with lower shell 102 at least in part via suitable fasteners extending through corresponding apertures 110 defined in panel 108 and lower shell 102. As described in greater detail below, in various embodiments, elongate body 104 and release member 106 are movable relative to panel 108 and thus may be only indirectly coupled with lower shell 102, e.g., via panel 108. Thus, in other words, elongate body 104 and release member 106 need not be independently or separately attached to lower shell 102.

[0038] Elongate body 104, which in this embodiment is generally rectangular in shape, defines a plurality of openings or apertures that each can have the same size or different sizes and / or shapes. As shown, for example, elongate body 104 defines a first opening 114 that defines a handle portion 116. Elongate body 104 also defines a second opening 118, a third opening 120, and a fourth opening 122. A greater or fewer number of openings can be provided in other embodiments. Openings 114, 118, 120, and 122 preferably are aligned with one another and are spaced apart from one another along the length of elongate body 104. As described in more detail below, each opening can define or correspond to a stop position (in extension or retraction) of elongate body 104. First opening 114 can define or correspond to a first position, second opening 118 can define or correspond to a second position, third opening 120 can define or correspond to a third position, and fourth opening 122 can define or correspond to a fourth position.

[0039] Release member 106 is coupled with elongate body 104 and movable relative thereto at least between a first, or lowered, position (FIG. 3) and a second, or raised, position (FIG. 4). In various embodiments, release member 106 can be biased into the lowered position, but this is not required in all embodiments. Release member 106 also defines a flange 124 that can be grasped by a user's fingers to urge release member 106 upwardly relative to elongate body 104 (e.g., against the bias) toward the raised position. In particular, release member 106 and flange 124 can be dimensioned such that a user grasping handle portion 116 with one hand can engage flange 124 with his or her fingers on the same hand.

[0040] Additionally, release member 106 in this embodiment defines a plurality of projections. The number, size, and shape of projections can vary in various embodiments, but in one embodiment, the number of projections on release member 106 corresponds to the number of openings 114, 118, 120, and 122, and this number likewise corresponds to the number of different positions to which the elongate body 104 can be moved. In general, the projections are disposed on release member 106 such that they are each at least partially disposed within a corresponding opening defined in elongate body 104. In the illustrated embodiment, release member 106 defines a first projection 126 disposed in first opening 114, a second projection 128 disposed in second opening 118, a third projection 130 disposed in third opening 120, and a fourth projection 132 disposed in fourth opening 122. As best seen in FIGS. 3-4, when release member 106 is moved from the lowered position to the raised position, each projection 126, 128, 130, and 132 translates upwardly within its respective opening 114, 118, 120, and 122.

[0041] Panel 108 preferably defines at least one latch member 134 (examples of which are shown in FIGS. 2, 5, 17, and 20) that is selectively engageable with an individual opening 114, 118, 120, or 122 when the release member 106 is disposed in the lowered position. In some embodiments, the at least one latch member 134 comprises one projection or multiple discrete projections that are in selective engagement with one of the openings 114, 118, 120, and / or 122. Latch member 134 can be biased toward elongate body 104 or, e.g., into a position of engagement with each opening 114, 118, 120, or 122. Thus, when the latch member 134, or a component thereof, is received in any of openings 114, 118, 120, and 122, the elongate body 104 is prevented from movement relative to panel 108.

[0042] However, when release member 106 is moved to the raised position, the projection 126, 128, 130, or 132 that corresponds to the opening 114, 118, 120, or 122 in which the latch member 134 is received at that time will translate into engagement with the latch member 134 (or component thereof) to move it out of the corresponding opening 114, 118, 120, or 122. If release member 106 is moved back to the lowered position, the latch member 134 will reenter the corresponding opening 114, 118, 120, or 122. But as long as release member 106 is maintained in the raised position, elongate body 104 is movable relative to the panel 108 without the latch member 134 engaging any of the openings 114, 118, 120, or 122. This allows elongate body 104 to be moved relative to panel 108 to any desired position.

[0043] As elongate body 104 is moved upwardly or downwardly relative to panel 108, latch member 134 will no longer be in alignment with one of the openings 114, 118, 120, and / or 122, and it may instead be in sliding engagement with a portion of elongate body 104 in which no opening is defined. When latch member 134 and elongate body 104 are in this configuration, release member 106 can be moved to the lowered position and elongate body 104 will remain moveable relative to panel 108 until latch member 134 comes into engagement with another one of the openings 114, 118, 120, and / or 122.

[0044] Once elongate body 104 is disposed at or near its desired position (e.g., a desired height above lower shell 102 or a desired amount of extension or retraction), release member 106 can be moved to its lowered position (if it is not in that position already). At that time, if latch member 134 is aligned with (e.g., disposed opposite) one of the openings 114, 118, 120, or 122, it will enter (e.g., be biased into engagement with) such opening and thereby “lock” elongate body 104 into that position. If latch member 134 is not aligned with one of the openings, then it will instead remain in sliding engagement with a portion of elongate body 104. As will be appreciated, latch member 134 can have various sizes and shapes in various embodiments, and its dimensions may vary as needed or desired to accommodate the dimensions of each opening 114, 118, 120, and / or 122.

[0045] FIGS. 2 and 5-8 show movement (e.g., extension) of elongate body 104 of handle assembly 100 to and between various positions relative to panel 108 and / or lower shell 102. In FIG. 2, elongate body 104 is in a first position, which may be a fully retracted position. Here, release member 106 is in a lowered position and latch member 134 is disposed within first opening 110. To move elongate body 104 to a deployed or extended position, a user can lift release member 106 to the raised position, as shown in FIG. 5. Here, first projection 126 engages and / or interferes with latch member 134, pushing latch member 134 out of first opening 110. As a result, latch member 134 no longer interferes with movement of elongate body 104, and elongate body 104 can be moved upwardly relative to panel 108 and lower shell 102. After the user does so, she can return release member 106 to its lowered position and continue to raise elongate body 104 relative to panel 108. This is shown in FIG. 6. Latch member 134 will slide along elongate body 104 until latch member 134 encounters second opening 118. If the user retains release member 106 in the raised position while lifting upward on elongate body 104, second projection 128 will block second opening 118 and / or prevent latch member 134 from entering, such that the user can continue lifting elongate body 104 upwardly past that second opening 118 and / or the second position, for instance to the third position shown in FIG. 7. However, if the user has returned release member 106 to its lowered position as described above, elongate body 104 will stop at the second position once the user raises elongate body 104 to a position where latch member 134 can move into engagement with second opening 118. Similar actuation of release member 106 and upward movement of elongate body 104 relative to panel 108 allows the user to move elongate body 104 to the third position, in which latch member 134 is disposed within third opening 120, as shown in FIG. 7, and to the fourth position, in which latch member 134 is disposed within fourth opening 122, as shown in FIG. 8. The latter may be a fully extended or fully deployed position of elongate body 104.

[0046] To return elongate body 104 to the retracted position, the user can move release member 106 to the raised position, causing projection 132 to engage and / or interfere with latch member 134 to push latch member 134 out of fourth opening 122, and then begin to lower elongate body 104 relative to panel 108. By maintaining release member 106 in the raised position, the user can continue to move elongate body 104 downwardly, such that latch member 134 does not engage either third opening 120 or second opening 118 as they move past. The user can then move release member 106 to the lowered position and continue to lower or retract elongate body 104 until latch member 134 again engages first opening 114.

[0047] Additional aspects of a handle assembly 200 in accordance with an embodiment of the present invention are described with reference to FIGS. 9-20. In general, handle assembly 200 comprises an elongate body 204, a release member 206, and a panel 208. Elongate body 204 has a first side 210 and an opposite second side 212. Elongate body 204 further defines a first opening 214 and comprises a handle portion 216. Elongate body 204 also includes second, third, and fourth openings 218, 220, and 222. Release member 206 defines a flange 224 and projections 226, 228, 230, and 232. Panel 208 defines a latch member 234.

[0048] FIGS. 9-12 depict certain operations of the elongate body 204 and release member 206 of handle assembly 200 wherein the panel 208 is not shown. FIGS. 13-14 show elongate body 204, FIGS. 15-16 show release member 206, and FIGS. 17-18 show panel 208. FIGS. 19-20 are exploded views of handle assembly 200.

[0049] In this embodiment, release member is coupled with the first side 210 of elongate body 204. For example, in various embodiments, release member 206 preferably defines at least one opening, and elongate body 204 preferably defines at least one projection disposed at least partially within the at least one opening when the release member 206 is coupled with elongate body 204. With reference to FIGS. 9-16, release member 206 defines three openings or slots 236, 238, and 240. Correspondingly, elongate body includes three projections 242, 244, and 246 disposed on first side 210. When release member 206 is disposed against elongate body 204, projections 242, 244, and 246 align with slots 236, 238, and 240. Of course, in other embodiments, additional or fewer slots and projections, of various shapes, could be provided.

[0050] Each projection 242, 244, and 246 comprises a flange 248 in this embodiment. Each flange 248 could be formed as a unitary part of each projection in some embodiments, but in this embodiment flanges 248 are separate components attached to each projection 242, 244, and 246 via a suitable fastener (e.g., a screw) 250 receivable in an aperture (e.g., a threaded hole) defined in each projection. As release member 206 moves between a lowered position (FIG. 9) and a raised position (FIG. 10), each respective slot 236, 238, and 240 translates about each flange 248 and respective projection 242, 244, and 246. Further, as best seen in FIGS. 9-10, flanges 248 have a first lateral dimension that is greater than a second lateral dimension of each respective slot 236, 238, and 240. As a result, release member 206 is slidably or movably coupled with elongate body 204.

[0051] Also, in certain embodiments, at least one spring is located between release member 206 and elongate body 204 to bias release member 206 toward the first or lowered position. With reference to FIGS. 13, 16, 19, and 20, for example, elongate body 204 defines a pair of channels 252 which in this embodiment resemble a half-cylinder and are disposed at the end of elongate body opposite handle portion 216. These example channels 252 are open at their respective lower ends and terminate in a rounded wall 254 at their respective upper ends. Correspondingly, release member 206 defines a pair of channels 256 which also resemble a half-cylinder and are disposed at the end of release member 206 opposite flange 224. These example channels 256 are open at their respective upper ends and terminate in a rounded wall 258 at their respective lower ends. Rounded walls 254 are dimensioned to translate within channels 256, and rounded walls 258 are dimensioned to translate within channels 252, and channels 252 and 256 together can form a substantially cylindrical volume. As shown in FIGS. 20-21, when release member 206 is coupled with elongate body 204, a pair of springs 260 (e.g., helical compression springs) are disposed in the volume defined by channels 252 and 256, with one end of each spring in engagement with a wall 258 and the opposite end of each spring in engagement with a wall 254. As release member 206 moves between a lowered position (FIG. 9) and a raised position (FIG. 10), each respective spring 260 is compressed between walls 258 and 254. In the lowered position of release member 206, each respective spring 260 is uncompressed. As a result, release member 206 is biased toward the lowered position.

[0052] As shown in FIGS. 13-14, elongate body 204 in this embodiment is generally rectangular in shape and defines a proximal end 259, a distal end 261, and a longitudinal axis 262 (FIG. 14). Handle portion 216 is disposed at distal end 261 in this embodiment. As noted above, elongate body 204 in this embodiment defines openings or apertures 214, 218, 220, and 222. Openings 214, 218, 220, and 222 are disposed along longitudinal axis 262 in this embodiment. Correspondingly, as shown in FIGS. 15-16, release member 206 also is generally rectangular in shape in this example and has a longitudinal axis that is aligned with longitudinal axis 262 when release member 206 is coupled with elongate body 204. When handle assembly 200 is assembled, movement of release member 206 between the lowered position and the raised position causes movement of projections 226, 228, 230, and 232 within the respective openings 214, 218, 220, and 222 along longitudinal axis 262. Although these openings each may have different shapes and sizes, in this embodiment they are each centered on longitudinal axis 262 in this example. The relative positions and spacing of openings 214, 218, 220, and 222 can vary, as needed or desired, to define stop positions in various locations.

[0053] In various embodiments described herein, each of the openings of a given elongate body 104, 204 preferably is sized to receive both a corresponding projection of a given release member 106, 206 and, selectively, the at least one latch member 134, 234 defined on a given panel 108, 208, or a component (such as one or more projections) thereof. As those of skill in the art will appreciate, the shape and / or dimensions of each such opening can vary in various embodiments, as needed or desired, while still accomplishing this purpose.

[0054] One example is shown in FIGS. 11-14 and 20. In this embodiment, each opening 214, 218, 220, and 222 comprises a generally rectangular lower portion 264, 266, 268, and 270 (FIG. 14) sized to receive a respective release member 206 projection 226, 228, 230, and 232. Each such lower portion is disposed beneath and connected to a generally rectangular upper portion 272, 276, 278, and 280 (FIG. 14) into which each respective projection 226, 228, 230, and 232 translates in response to movement of release member 206 from the lowered to the raised position. In this particular embodiment, the lateral dimension of lower portions 266 and 268 are the same as the lateral dimension of respective upper portions 276 and 278, while the lateral dimensions of lower portions 264 and 270 are smaller than the lateral dimensions of respective upper portions 272 and 280, but the lateral dimensions can vary in other embodiments. As seen in FIG. 14, lower portions 264, 266, 268, and 270 and upper portions 272, 276, 278, and 280 extend along longitudinal axis 262.

[0055] Also as explained herein, a latch member 234 of panel 208 (or a component thereof, such as one or more projections 296) is configured to selectively engage each opening 214, 218, 220, and 222. In the case of first opening 214, upper portion 272 defines a shoulder 282. When release member 206 is disposed in its lowered position and the at least one projection 296 of panel 208 is disposed in first opening 214, the at least one panel 208 projection 296 will be disposed on or above shoulder 282 (and above first projection 226 of release member 206). Thus, in this position, interference between shoulder 282 and the at least one projection 296 will prevent upward movement of elongate body 204.

[0056] In the case of second, third, and fourth openings 218, 220, and 222, each such opening defines laterally opposed notches 284, in each case disposed just above the respective lower portions 266, 268, and 270. In each such opening, the respective laterally opposed notches 284 together can define a slot sized to receive the at least one panel 208 projection 296 therein. Again, as seen in FIG. 14, the portions of openings 218, 220, and 222 that are defined by notches 284 extend along a transverse axis 285.

[0057] Thus, when release member 206 is disposed in its lowered position and the at least one projection 296 of panel 208 is disposed in second opening 218, the at least one panel 208 projection 296 will be disposed in the slot defined by notches 284 (and above second projection 228 of release member 206). Interference between the projection 296 and the slot defined by notches 284 will prevent upward or downward movement of elongate body 204. Engagement between projection 296 and the slots defined in each of openings 220 and 222 is similar to that described above.

[0058] FIGS. 17-18 are perspective views of an example embodiment of panel 208, which can be a portion of an exterior shell of a carrying case. As shown in FIGS. 19-20, panel 208 is disposed on the second side 212 of elongate body 204. In the illustrated embodiment, panel 208 defines a body portion 286 and a tongue portion 288. Tongue portion 288 can be defined in body portion 286 by a pair of parallel slots 290 and can extend between a proximal end 292 and a distal end 294. In various embodiments, tongue portion 288 is curved relative to body portion 286, e.g., in a direction facing the carrying case or handle assembly components to which panel 208 will be attached. In some handle assembly 200 embodiments, the distal end 294 of tongue portion 288 is biased toward or into engagement with the elongate body 204. Tongue portion 288 thus can be flexible and bendable away from its biased position, e.g., in response to interference with a projection of release member 206.

[0059] As noted above, panel 208 includes latch member 234. In this embodiment, latch member 234 comprises tongue portion 288 and a projection 296 at or proximate distal end 294 of tongue portion 288. Projection 296, which can be at least one lip or flange or the like in various embodiments, faces the elongate body 204 in handle assembly 200. As discussed above, projection 296 is dimensioned to selectively engage slots formed by the notches 284 in openings 218, 220, and 222. Correspondingly, the latch member 234 of panel 208 is configured to engage with one or more projections of release member 206, such as projections 226, 228, 230, and 232 shown in FIGS. 15-16. In this embodiment, projections 226, 228, 230, and 232 are generally boxlike in shape, with generally rectangular lower surfaces and flat sides. However, on the sides of projections 226, 228, 230, and 232 that face panel 208 in handle assembly 200, the sides can transition from a flat surface 297 to a rounded upper surface 298 and to an angled surface 300. While the shapes and contours can vary in various embodiments, it will be appreciated that the shapes of projections 226, 228, 230, and 232 are configured, during engagement between the projections 226, 228, 230, and 232 and the projection 296, to translate upward movement of release member 206 into movement of latch member 234 out of engagement with elongate body 204. In some embodiments, projections 226, 228, 230, and 232 define a cam surface configured to engage with the at least one projection 296, which acts as a follower.

[0060] Of course, various embodiments of the present invention can include one or more latch members that are different than latch members 134, 234 shown herein, and in some embodiments the latch members need not be disposed on a panel 108, 208 at all. For example, in some embodiments, a latch member analogous to latch member 234 could be on side 210 of elongate body 204 and release member 206 could be on side 212 of elongate body 204. Additionally, one or more projections or other latch members could be coupled with or part of a carrying case's exterior shell (e.g., lower shell 102) in some embodiments.

[0061] Other variations are possible and within the scope of the present invention. For instance, in various embodiments, either or both of elongate body 204 and / or release member 206 could be provided in multiple pieces, rather than as single unitary components. As such, other embodiments could include more than one elongate body 204 and / or more than one release member 206. Likewise, the various openings and projections discussed above could have different numbers, shapes, and / or dimensions while performing the same or similar functions to those described herein. Finally, although one or more preferred embodiments have been discussed herein in the context of a hard-sided case for carrying equipment, luggage, or the like, those of skill in the art will appreciate that the present invention is not so limited. In particular, it is contemplated that embodiments of the present invention may be used with a variety of types of cases, including both hard-and soft-sided cases used for any purpose.

[0062] Based on the foregoing, it will be appreciated that embodiments of the invention provide improved equipment cases, multi-stage handle assemblies, and methods of operating carrying cases and handle assemblies. Among other things, in embodiments of the present invention, a carrying case can be provided with a handle assembly that is extendable and retractable in multiple stages, e.g., it can be moved relative to the carrying case to various predefined stop positions. Thus, such a carrying case can have a handle that is adjustable to accommodate both taller and shorter users, as opposed to a handle that extends only to a single position. In various embodiments, a person can operate such a handle assembly using only one hand (e.g., the hand that is already grasping the handle). Also as described herein, embodiments of the handle assembly have a low profile, robust construction, and do not require the use of any buttons.

[0063] Many modifications and other embodiments of the inventions set forth herein will come to mind to one skilled in the art to which these inventions pertain having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the inventions are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Moreover, although the foregoing descriptions and the associated drawings describe exemplary embodiments in the context of certain exemplary combinations of elements and / or functions, it should be appreciated that different combinations of elements and / or functions may be provided by alternative embodiments without departing from the scope of the appended claims. In this regard, for example, different combinations of elements and / or functions than those explicitly described above are also contemplated as may be set forth in some of the appended claims. In cases where advantages, benefits or solutions to problems are described herein, it should be appreciated that such advantages, benefits and / or solutions may be applicable to some example embodiments, but not necessarily all example embodiments.
