As shown in Fig. 9, a bracket member 62 is provided. The bracket member 62 comprises a selectively rotatable portion having first and second apertures for receiving the collapsible members 54a, 54b of the handle portion 52 and wherein the collapsible members 54a, 54b are translatable through the rotatable bracket 62 along at least a portion of the lengths of the collapsible members 54a, 54b. To convert the handle portion 52 from a first position of use (see Fig. 9) to a second position of use wherein the handle portion 52 is rotated and provided at an angle with respect to the base portion 40, a control mechanism is activated and allows the rotatable bracket 62 and the handle portion 52 to rotate. The base portion 40 comprises an aperture, a cut-out, or recess 50 to enable this rotation. In preferred embodiments, an angled recess 50 is provided in the base portion to enable and/or limit rotation of the rotatable bracket 62 and the handle portion 52.

Fig. 10 is an exploded perspective view of the handle portion 52 of the embodiment of Fig. 9. As shown, the handle portion 52 comprises a grasping portion 56 provided at one end of first and second collapsible members 54a, 54b. The collapsible members 54a, 54b extend through a selectively rotatable bracket member 62. A second bracket member 68 is provided at a second end of the handle member, generally opposite from the grasping portion 56. When assembled, the handle member comprises a grasping portion 56 on a first end of the collapsible members 54, 54b and a second bracket at an opposed second end of the collapsible members. The handle is translatable between a stored position wherein the grasping portion is provided proximal to the bracket portion 62, and an extended position wherein the second bracket member 68 is brought into contact with the bracket member 62 (See Fig. 9).

In various embodiments, the present disclosure contemplates a handle portion 52 comprising elongate wire members 64a, 64b extending along and preferably internal to the collapsible members 54a, 54b and wherein the collapsible members 54a, 54b comprise elongate tubular members. The elongate wire members 64a, 64b comprise force- transmitting means provided to convert a force or movement applied to the push-button 60 on grasping portion 56 to additional features. The wire members 64a, 64b act upon locking pins to manipulate the locking pins and selectively lock and unlock the collapsible members so that they may be extended or retracted based on a user preference. Additionally, and depending upon a position of a rotatable portion 58 of the grasping portion 56, a movement of the push-button and the wire members unlocks a rotation of the bracket member 62 to enable rotation of the handle member 52 and allows the handle member 52 to be provide in an angled position.

As shown in Fig. 9, the rotatable bracket member 62 is provided proximal to a first end of the base portion 40. The bracket member 62 is preferably fixed in a lateral and longitudinal direction and rotatable about an axis. In other words, the rotatable bracket 62 is selectively rotatable with respect to the base portion 40, but is otherwise in a fixed relative position with respect to the base portion 40. The second bracket member 68 is substantially fixed to a second end of the collapsible members 54a, 54b and translates with the collapsible members between a stored position and an extended position wherein the second bracket member 68 is brought into contact with the rotatable bracket member 62, as shown in Fig. 9.

In the depicted embodiment, a handle portion 52 is provided wherein a grasping portion 56 comprises a rotatable portion 58 that is rotatable between at least a first and second position. The rotational position of the rotatable portion 58 dictates or governs the overall displacement of distal ends 65 of the wire members 64. When the rotatable portion 58 is provided in a first position, a depression of the push-button 60 extends the wire members 64 to a first predetermined position. The first predetermined position corresponds to unlocking a first locking member that allows the collapsible members 54a, 54b to extend, but does not allow for or unlock rotation of the bracket 62 and a rotational position of at least the rotating bracket 62 remains substantially fixed. Thus, even when the handle portion 52 is extracted or expanded to a first position of use, the handle portion 52 and collapsible members 54a, 54b are provided substantially parallel to at least a planar portion 43 of a base portion 40 and the luggage device is adapted to be towed, wheeled, manipulated, etc. on the first pair of wheels 46a, 46b.

When the rotatable portion 58 of the grasping portion 56 is rotated to a second position, depression of the push button enables extension of the collapsible members 54a, 54b and unlocks additional locking members to enable rotation of the bracket 62 such that the handle portion 52 may rotate to an angled position with respect to at least the planar portion 43 of the base 40. In various embodiments, the angled position of the handle portion 52 comprises an angle with respect to the planar portion 43 and/or ground or floor surface of between approximately 20 degrees and approximately 80 degrees. In preferred embodiments, the angled position of the handle portion 52 comprises an angle with respect to the planar portion 43 and/or ground or floor surface of between approximately 40 degrees and approximately 50 degrees, and most preferably of approximately 45 degrees. It is contemplated that the planar portion 43, and a plane extending therefrom, comprises a surface that is substantially parallel to a ground or floor surface when each of the two pairs of wheels are provided in contact with the ground or floor surface. It will be recognized, however, that the planar portion 43 of the base portion 40 need not be exactly parallel to the ground surface. Indeed, the orientation of the planar portion 43 and a ground surface may vary based on contours provided in the base portion 40, relative sizes of the opposing pairs of wheels, etc.

Referring to Fig. 10, various unlocking features are shown in an exploded state. As shown a grasping portion 56 comprises a rotatable portion 58 and a push button 60. The rotatable portion 58 is rotatable between at least a first position and a second position. The first position enables a displacement of the wire members 64a, 64b by a first amount. The second position enables a displacement of the wire members 64a, 64b by a second amount, and wherein the second amount is greater than the first. A depression of the push button 60 induces a linear movement of the elongate wire members 64a, 64b. The second ends of the wire members 64a, 64b comprise push boards 65. The push boards 65 are provided in the form of flanges or other extensions adapted to transmit a force from the wire members 64a, 64b to unlock various locking elements, such as one or more lock pins. The one or more lock pins are displaceable in a direction substantially perpendicular to a longitudinal axis of the collapsible members and the wire members. In various embodiments, a cammed or ramped surface is provided to convert a linear motion of the wire members in a first direction to a linear potion of the lock pins in a second, substantially perpendicular direction. The lock pins are moveable in and out of rigid portions of the bag, such movement corresponding to a locking and unlocking motion of the handle member 52 and/or the bracket 62.

In one embodiment, a device is provided wherein a first rotational position of the rotatable portion 58 of the grasping member 56 comprises a position wherein the pushbutton 60 and rotatable portion 58 are provided in a first position, and the push-button 60 preferable extends upwards as in conventional devices. In such a position, activation or depression of the push button unlocks first lock pins 75 associated with extension of the handle 52. The lock pins 75 are preferably biased toward a locking position by a coil spring or similar member.

As shown in Fig. 10, a second bracket 68 comprises biased locking pins 76 that are adapted to secure the second bracket 68 and the handle 52 in a stored position (see Fig. 9) and to engage the rotatable bracket 62 in an extended position and when desired by a user.

The rotatable bracket 62 comprises first and second axles 74 that enable rotation of the rotatable bracket 62 when associated lock pins are released. In various embodiments, a single axle may extend through the bracket 62 and be provided in communication with a luggage device. The axles 74 may be biased by one or more springs to bias or urge the bracket 62 to a first or second position.

In the embodiment provided in Fig. 10, the collapsible members 54 comprise a first pair of members 54a, 54b and a second pair of members 54c, 54d. The first pair of members 54a, 54b extend or telescope outwardly from the second pair of member 54c, 54d when two-wheeled carry (Fig. 9) is desired. The second pair of members 54c, 54d and the second bracket 68 provided on a distal end of the second pair of members 54c, 54d remain substantially fixed when the grasping member 56 and first pair of collapsible members 54a, 54b are extended to a first position of use. In a second position of use, the first pair of members 54a, 54b are extended with respect to the second pair of members. Additionally, the second pair of members 54c, 54d are extended with respect to the bag such that the second bracket 68 is brought into communication with the rotatable bracket 62. The second position thus comprises a greater overall extended handle 52 length as the first position. A stored or collapsible position comprises the first pair of collapsible members 54a, 54b being collapsed or extending into the second pair of members 54c, 54d and both pairs being retracted such that the grasping portion 56 of the handle is provided proximal to the base portion 40 of a luggage item.

To extend a first pair of collapsible members 54a, 54b and the grasping portion 56 to a first position of use, the rotatable portion 58 of the grasping portion 56 is provided in a first position (see Fig. 9). The push button 60 is depressed, which extends the wire members 64a, 64b and associated push boards 65 by a first distance. The push boards 65 act upon push pins 70, and cause an unlocking of a first pair of lock pins 75. The unlocking of the first pair of lock pins 75 enables the first pair of collapsible members 54a, 54b to extend upwardly with respect to other features of the bag, and the bracket 62 and second pair of collapsible members 54a, 54b remain substantially unmoved and unaffected. This unlocking motion allows the grasping portion 56 to be extended upwardly to a first position of use wherein the first lock pins 75 are preferably biased outwardly to temporarily lock the handle portion in the first position of use.

To extend the handle 52 to a second position of use, the rotatable portion 58 of the handle is rotated to a second position. In certain embodiments, the second position comprises a position wherein the push button 60 is provided substantially perpendicular to its position or location in the first position of use. This rotation of the rotatable portion 58 allows the wire members 64a, 64b and associated push boards 65 to extend by a second distance. In the depicted embodiment, the second distance is greater than the first distance. The movement of the push board 65 by the second distance causes an unlocking of the first pair of lock pins 75 as described above and further causes a similar unlocking action of a second pair of lock pins 76 provided in association with the second bracket 68. The second bracket 68 and second pair of collapsible members 54c, 54d are thus allowed to extend upwardly, and the second bracket 68 is brought into contact with the rotatable bracket 62. Without the second pair of lock pins 76 preventing rotation of the bracket 62, the entire handle and bracket 62 are allowed to rotate to an angle that enables the device to be towed an all four wheels. The first pair of collapsible members 54a, 54b are also allowed to telescope or extend outwardly from the second pair of collapsible members 54c, 54d.

Fig. 11 is a perspective view showing the base portion 40 provided in a second position of use wherein four-wheeled carry or movement of the device is enabled. As described herein, telescoping collapsible members 54a, 54b, 54c, 54d are extended with respect to each other and with respect to the base portion 40. The second bracket 68 is brought into contact with the rotatable bracket 62, and the handle 52 is rotated to an angle that allows a user to manipulate the handle 52 and associate luggage item when the base position 40 is provided with all four wheels in contact with a ground surface.

Although Figs. 9-11 of the present disclosure provide a device with a pair of substantially parallel collapsible members, alternative embodiments contemplate a handle portion comprising a single telescoping or collapsible member. For example, a single collapsible may be provided in combination with the features shown and described herein including, for example, the rotatable bracket 62. The single collapsible member may be centered on the base portion, or provided in any number of desired orientations. The single collapsible member may include, for example, a grasping portion similar to that shown and described herein and extending laterally away from the collapsible member in two directions.
