Title: Luggage container having telescoping transport hooks

Description:
FIELD OF THE INVENTION 
     The present invention relates generally to luggage containers such as suitcases, and more particularly to luggage containers that include extendible or telescoping handle assemblies, and further to telescoping handle assemblies that include hook portions to hook over a portion of a person&#39;s body so that they can pull the luggage container in a hands-free manner. 
     BACKGROUND OF THE INVENTION 
     Luggage is commonly provided with telescoping handles that extend from, and collapse at the top or upper portion of the luggage. Typically the telescoping segments are slightly shorter than the luggage case is tall, and are housed within a portion of the back side of the luggage case. As the luggage case is typically also provided with two or more wheel elements, this allows a user to pull or otherwise control the luggage case while the luggage case rolls on the floor or other surface over which the user is traveling by extending the handle and pulling on the extended handle. Typically the user will adjust the handle so that it reaches the user&#39;s hand when their hand is held around waist level, allowing the luggage container to be pulled beside or behind the user. 
     While the conventional telescoping handle is a desirable improvement over the even older standard configuration of luggage containers which did not have wheels or an extending handle, it still requires the use of one hand, which prevents use of that hand for other activities while pulling the luggage container. This can present a problem for someone who desires to have use of both hands free in the process of pulling a luggage container, such as a person who is also pushing a baby stroller, or anyone else who would prefer to have their hands free while moving their luggage. 
     Several devices have been created to assist people move luggage with them in a way that allow their hands to be free for other things. For example, there are harnesses that facilitate attaching a strap to the handle of a luggage container, and to a point on the person&#39;s back. Others have created slings or straps designed to be placed over a user&#39;s shoulder to attach a free end to the handle of the luggage container. While these allow effective pulling of a luggage container, when a person stops and the strap goes slack, there is no control over the luggage container, and the luggage container can continue moving, bumping into the user, or something or someone else. 
     Therefore, a need exists to overcome the problems with the prior art as discussed above.

     DETAILED DESCRIPTION 
     While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward. It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms. 
     The present invention provides a novel and efficient luggage case having a telescoping handle for handless towing. Embodiments of the invention provide a telescoping handle that extends sufficiently to engage the upper body of a user so that the user can tow or pull the luggage case without using a hand. In addition, embodiments of the invention provides that the telescoping handle can be concealed within a portion of the luggage case. 
       FIG.  1    is a front view sequence diagram of a luggage case  106  deploying a telescoping handle hook assembly for handless towing of the luggage case  106 , in accordance with some embodiments. In a first part  100  of the sequence, the handle is fully concealed within the luggage case  106 , and in particular in a cavity formed in a front side of the luggage case  106  that will be facing the user when the user tows the luggage case  106  using the handle. In the second part  102  the handle is partially extended, and in the third part  104  the handle is fully extended.  FIG.  2    shows the same sequence for a side view. 
     Referring collectively now to  FIGS.  1  &amp;  2   , the luggage case  106  has a case body having a front side, a back side, a top, and a bottom, and includes wheels  108  at a bottom side of the luggage case  106  adjacent the front side. In some embodiments skid posts  202  can be positioned on the other side of the bottom of the luggage case  106 , opposite the wheels, to prevent the luggage case  106  from rolling away. The handle assembly is accessible from the top  110  of the luggage case  106 , and includes a first telescoping section  112  and a second telescoping section  114 . The telescoping sections can collapse into a portion  200  on the front side of the luggage case  106  that is provided to house the telescoping sections  112 ,  114 . The telescoping sections  112 ,  114  can be made of coaxial metal tubing or cylindrical sections as is common for telescoping luggage handles. Each of the telescoping sections  112 ,  114  include a hook portion at the top of the telescoping sections  112 ,  114  that can include a cross member  116 ,  118 , respectively, and a downward portion  122 ,  120 , respectively. 
     As can be seen, in the collapsed position in the first part  100  of the sequence diagrams, the cross members  116 ,  118  oriented toward the opposite telescoping section  112 ,  114 , with the catch portions  120 ,  122  adjacent the main shaft of the opposite telescoping portion  112 ,  114 . Once the telescoping sections  112 ,  114  are raised sufficient for the catch portions to clear the top  110  of the luggage case, that can be pivoted as indicated by arrows  124  to be substantially parallel and extending forward of the luggage case  106 , such that the catch portions  120 ,  122  hang in front of the front of the luggage case  106  by about the distance of the cross members  116 ,  118 . In particular, in  FIG.  2    the third part  104  of the sequence shows of the top of the telescoping portion  112 , with cross member  116  and catch portion  122  form an inverted hook that can engage a user at the user&#39;s shoulders so the user can tow the luggage case without using either of the user&#39;s hands. Accordingly the telescoping sections  112 ,  114  can extend four or more feet from the top  110  of the luggage case, which is itself on the order of two or more feet tall, so as to fit most people. The telescoping sections  112 ,  114  can be adjustable with spring stops to select an appropriate height of the telescoping sections  112 ,  114 , as desired by the particular user. The cross members  116 ,  118  can be pivoted about the axis of telescoping sections  112 ,  114 , and there can be an interference built into the tubing so that the cross members can only be pivoted about ninety degrees, or some other selected angle, to prevent the cross members  116 ,  118  from pivoting off the user&#39;s shoulders. In  FIG.  2   , in the second part  102  of the sequence, it can be seen that the cross members  116 ,  118  can be offset from each other at their respective telescoping section to allow them collapse into the luggage case together. This is shown in  FIG.  3   . 
       FIG.  3    is a top view of a luggage case  300  having a telescoping handle hook assembly for handless towing retracted inside a hook concealer of the luggage case, in accordance with some embodiments. The top  302  of the luggage case  300  is seen, and includes a cavity  304  formed into the luggage case  300  from the top  302 . The cavity houses the telescoping sections  306 ,  308 , and in this view the axis of the telescoping section  306 ,  308  is in and out of the page. Cross member  310  is attached to telescoping section  306 , and has a horizontal axis that is offset from the vertical axis of the telescoping section  306 . Similarly, cross member  312  is attached to telescoping section  308  and is likewise offset from telescoping section  308 , in the opposite direction from that of cross member  310  relative to telescoping section  306 , allowing cross members  310 ,  312  to somewhat interleave with each other in the cavity  304 , when the telescoping sections  306 ,  308  are collapsed into the cavity  304  and not in use. Upon deployment, the telescoping sections  306 ,  308  can be extended upwards (e.g. out of the page), and cross members  310 ,  312  can be pivoted forward as indicated in  FIGS.  1 - 2   . By offsetting the cross members  310 ,  312  they can lay parallel to each other in the cavity  304 , and parallel to a line between the telescoping sections  306 ,  308 . 
       FIG.  4    is a side view  400  of a luggage case  402  having a telescoping handle hook deployed and extended to engage a user&#39;s shoulders to allow handless towing of the luggage case, in accordance with some embodiments. The luggage case  402  includes a portion  414  in which a cavity of formed to receive the telescoping handle assembly. That is the telescoping handle assembly can be collapsed and concealed in the cavity of the portion  414 . The telescoping handle assembly include telescoping portions such as telescoping section  404  that extends from the cavity in portion  414  in a telescoping manner. There can be three to four coaxial sections in the telescoping sections  404  so that the telescoping sections  404  can both fully collapse into the luggage case body, and extend far enough to engage a person&#39;s shoulders  412  assuming a person of approximate average height. The telescoping sections  404  are anchored in the luggage case such that they can only extend upward, or collapse downward. Thus, if the luggage case is leaned over, the telescoping sections  404  will lean with the luggage case  402 , and likewise, leaning or pulling on the extended telescoping sections  404  can cause the luggage case  402  to lean correspondingly. 
     Accordingly, a user  410  can extend the telescoping sections  404  such that a cross member  406  at the top end of each telescoping section is at a height such that the luggage case  402  will lean over when the cross member  406  is over the shoulder  412  of the user  410 . The catch portion  408  extends downward across a portion of the front of the user  410  to retain the telescoping assembly on the user&#39;s shoulder  412 . Accordingly, the user  410  can tow the luggage case  402  without using their hands while maintaining control over the luggage case  402 . The direct coupling between the user  410  and the luggage case created by the stiff telescoping sections  404  avoids problems associated with prior art luggage towing using straps or similar loose coupling structures. 
       FIG.  5    is a side view of a hook portion  500  of a telescoping hook handle, in accordance with some embodiments. The telescoping section  502 , which is anchored in the luggage case, connects to a cross member  504  at a hinge  508 . Likewise, the cross member  504 , at its opposite end, connects to a catch member  506  at a similar hinge  510 . The hinges  508 ,  510  allow movement of the cross member  504  relative to the telescoping section  502  as indicated by arrow  512 , and of the catch member  506  relative to the cross member  504  as indicated by arrow  514 . The structure at each hinge can limit the degree of movement. In some embodiments the cross member  504  can normally be held at a ninety degree angle to the telescoping section  502 , and the hinge  508  can allow another forty five degrees of angle. Likewise, hinge  510  can allow additional angle beyond ninety degrees between the cross member  504  and the catch member  506 . The freedom of movement provided by the hinges  508 ,  510  allows the hook portion to conform to various body sizes, as well as preferences for angle of towing the luggage case. 
       FIG.  6    is a detail of a joint forming a hook portion of a telescoping hook handle for a luggage case, in accordance with some embodiments. The upper portion of a telescoping section  602  is joined to a cross member  604  at a hinge  610 . The angle  612  between the telescoping section  602  and the cross member  604  is controlled by interference features. For example, to ensure a minimum angle, a stop feature  608  can bear against the bottom  606  of the cross member  604  when the cross member  604  is at the minimum angle relative to the telescoping section  602 . A maximum angle can be selected by the positioning of a second stop feature  614  on the heel of the cross member  604 , which bears against the top  616  of the telescoping section  602  when the maximum angle is reached. A coil spring around the pin of the hinge  610  can be used to bias the cross member  604  to the minimum angle position. A similar arrangement can be used at the hinge connecting the cross member  604  to the catch member (not shown) to control the minimum and maximum angles between the two members. 
       FIG.  7    is a front view of a top portion of a telescoping hook handle having a single main portion.  FIG.  8    shows the same device as in  FIG.  7    from a side view. In this arrangement, rather than there being two different telescoping section, there is one main telescoping portion  702  having a terminal section  704  that forms a “T” crossbar  706  having opposing ends. At each of the opposing ends is hook structure  708 ,  710 , Each of the hook structures include a vertical riser portion (e.g.  802 ) that extends vertically from the T-shaped crossbar  706 . The vertical riser portion joins to a cross member (e.g.  803 ), which in turn joins to a catch member (e.g.  804 ). Hinges  806 ,  808  can allow movement of the cross and catch members as described in regard to  FIGS.  5 - 6   . The hook portions  708 ,  710  can be configured to pivot on the cross bar  706  toward each other so that the handle assembly and be collapsed into the luggage case substantially as described in regard to  FIG.  3   . 
       FIG.  9    is a side view of a first side of a luggage case  902  including telescoping shoulder hook handles that are partially extended, as shown, in accordance with some embodiments. The luggage case  902  includes one or more telescoping extensions  904  that are housed inside a corresponding channel  908  when collapsed. The extensions  904  comprise telescoping tubes that can be adjusted to selected lengths as desired by a user. That is, the extensions  904  can be adjusted to different selectable lengths to suit different users of different heights. Specifically, the user can extend the extensions  904 , as indicated by arrow  912 , to a distance that allows the user to place shoulder hooks  906  over the user&#39;s shoulders, allowing the user to tow the luggage case  902  behind the user as the user walks. To accomplish this, the extensions  904  have to be able to achieve a length such that the luggage case  902  will lean over and tend to stay leaned over at an angle, such as by shifting the center of gravity of the luggage case forward of the wheels  914 , otherwise the luggage case  902  will tend to stand back up vertically as shown here. Thus, the extensions  904  may contain as many as four telescoping sections to accommodate people of different heights. 
     The shoulder hooks  906  are mounted on a rotating connector at the top of the extensions  904 , which allows the shoulder hooks  906  to rotate one hundred eighty degrees from the position shown here, allowing them to be placed over a user&#39;s shoulders. When not being used, the shoulder hooks  906  can be placed in the position shown, and the extensions  904  collapsed into the channel  908 , with the shoulder hooks  906  being lowered into pockets  910  formed in the luggage case  902 . The pockets  910 , like the channel  908 , can be formed in the wall of the luggage case  902 , which can be a two-part wall, with an inner wall layer and an outer wall layer, where the pockets  910  and channel  908  are formed between the inner and outer wall layers. 
     In  FIG.  10    is a side view of a second side of a luggage case  1002  including telescoping shoulder hook handles  1012 ,  1014  that are partially extended, in accordance with some embodiments.  FIG.  10    shows an embodiment that uses two extensions  1004 ,  1006  which are independent of each other, and are each coupled, at their distal end, to a respective shoulder hook  1012 ,  1014 . The shoulder hooks  1012 ,  1014  have the same general shape as shoulder hook  906 , and can be rotated about the axis of their respective extension  1004 ,  1006  as indicated by arrows  1016 ,  1018 , and have a range of rotation of at least one hundred eighty degrees. The extensions  1004 ,  1006  are comprised of telescoping tubular members that can be adjusted in length to a desired length, and can collapse into a base tube member that is located in a channel  1008 ,  1010  in the wall of the luggage case. 
       FIG.  11    is a side view of a luggage case  1102  having a partially extended telescoping extension  1104  that couples to a member having shoulder hooks  1106 ,  1108 , in accordance with some embodiments. Shoulder hooks  1106 ,  1108  have the same general shape as shoulder hook  906 , but are attached to a horizontal cross member  1110  that is in turn mounted on the extension  1104 . The cross member  1110  rotates, as indicated by arrow  1112 , on the axis of the extension  1104 . The extension  1104  is a telescoping assembly of co-axial tube members, as is well known, and can be adjusted to a desired length such as by a sprung protrusion in one of the telescoping members that can extend through one of several holes in another, outer telescoping member. The extension  1104  can collapse into a channel  1118  formed in the wall of the luggage case  1102 , and similarly, the cross member  1110  and shoulder hooks  1106 ,  1108  can sit in pockets  1114 ,  1116  and a connecting trough/pocket between pockets  1114 ,  1116 , as shown in  FIG.  12   .  FIG.  12    shows a top view of luggage case  1102  with the extension  1104  collapsed so that shoulder hooks  1106 ,  1108  are sitting in pockets  1114 ,  1116 . To allow a user to easily pull/lift the shoulder hooks  1106 ,  1108  out of the luggage case  1102 , there can be a corresponding access depression  1202 ,  1204  for each shoulder hook  1106 ,  1108  formed in the luggage case. The depressions  1202 ,  1204  allow a user to insert a finger under the shoulder hooks  1106 ,  1108 . Using a single extension  1104 , instead of two (as in  FIG.  10   ), allows a user to turn their shoulders with the shoulder hooks over their shoulders.  
       FIG.  13    is a side view of a luggage case  1302  having a telescoping shoulder hook portion with a brace member, in accordance with some embodiments. This allows a lower effective connection point to the user, and an increased angle at which the luggage case is leaned when being towed by the shoulder hooks. An extension  1304  includes a pivot point  1312  that divides the extension  1304  into a lower portion  1314  and an upper portion  1316 . The pivot point can be an adjustable hinge that can be locked in position. The upper portion  1316  can pivot backward from the position shown at the pivot point  1312 . The lower portion  1314  is telescoping, and includes several coaxial/concentric tube members that collapse or extend as needed by the user. The arrangement of the telescoping shoulder hook portion shown here can be substantially similar to that shown in  FIG.  16   . The extension  1304  can collapse into a channel  1310  in the luggage case  1302 . 
     At the top of the extension  1304  is a cross member to which a pair of shoulder hooks  1306  are connected. The cross member can rotate about an axis of the extension  1304 , as indicated by arrow  1318 . A brace member  1308  couples, at a first end, to the lower portion  1314  of the extension  1304 , and at a second end to the upper portion  1316  of the extension  1304 . The brace member  1308  holds the lower and upper portions  1314 ,  1316  in a fixed position once the upper portion  1316  is tilted at the pivot point  1312 , as shown in  FIG.  14   . In  FIG.  14   , the luggage case  1302  is shown leaned over at an angle, as it would be when being towed by a person with the shoulder hooks  1306  over the person&#39;s shoulders. The brace member  1308  can include a sliding and locking clasp  1402  at the lower end of the brace member  1308  that can encircle the lower portion  1314  of the extension  1304 , and can be adjusted to frictionally engage the lower portion  1314  of the extension  1304 . A similar clasp  1404  can be provided at the top of the brace member  1308  to engage the upper portion  1316  of extension  1304 . This allows the upper portion  1316  to be tilted at an angle, relative to the lower portion  1314 , and held in that position. When so fixed, with the shoulder hooks  1306  over the user&#39;s shoulders, the connection point to the user is essentially at the pivot point  1312 . This ensures that a taller person can still use the shoulder hook assembly to tow the luggage case  1302  as the angle of lean of the luggage case  1302  ensures that the luggage case  1302  will not tend to “stand up,” and will remain leaned over while being towed. 
       FIG.  15    is a side view of a shoulder hook portion for a telescoping extension of a luggage case, using a strap to secure the shoulder hook in place, in accordance with some embodiments. A strap  1510  can be used in place of a bracing member (e.g.  1308 ) to hold the shoulder hook  1502  in place over a user&#39;s shoulders. A telescoping extension  1500  includes a lower portion  1506  and an upper portion  1504  which are coupled together at a pivot point  1512 . The upper portion  1504  supports the shoulder hooks  1502  (only one is seen here in the side view). At or near the base of the upper portion  1504  is a strap loop  1508  for retaining a strap  1510  that passes through the strap loop  1508 . The strap  1510  can pass around the user at about torso at chest level to hold the upper portion  1504  at substantially a vertical orientation, allowing an increased angle of lean of the luggage case (not shown here). 
       FIG.  16    shows a shoulder hook extension for a luggage case including a rotating and pivoting connection, in accordance with some embodiments. The assembly includes two shoulder hooks  1602 ,  1604  which are shaped to go over a user&#39;s shoulders. The shoulder hooks  1602 ,  1604  are each connected to a cross member  1606  at opposite ends of the cross member  1606 . The cross member  1606  is coupled, at its middle, to the upper portion  1608  of an extension that telescopes to collapse into a luggage case. At the bottom of the upper portion  1608  is a rotating swivel member  1610  which rotate about the axis of the upper portion  1608  and is connected thereto. The swivel member  1610  can include a connection tongue that connects to a corresponding tongue  1616  in a way that allows the lower portion  1612  to pivot. The connection can be made by a transverse pin or equivalent that passes through both portions in a way that allows them to move relative to each other. Thus, the action of the pivot interface and the rotation of the swivel member  1610  allows a universal joint effect that allows for easier towing of a luggage case by a person as it accommodates the motions of a person as they walk and turn. The lower portion  1612  can telescope with one or more telescoping members  1614  to collapse into the luggage case for storage when the user is not using the shoulder hooks to tow the luggage case. As shown there, the swivel member  1610  is located below the cross member  1606 . The distance from the cross member  1606  can be on the order of zero to twelve inches in some embodiments. That is, the swivel could be located at or on the cross member  1606  at point  1618 . A ball joint or other equivalent structure could be used in place of the swivel, as well. The telescoping members  1614  can then be connected directly to the center of the cross member  1606 . 
       FIG.  17    shows a partial cut-away view of an extension portion for an extendible shoulder hook having a shock absorbing component within the extension, in accordance with some embodiments. A further degree of freedom can be accomplished by not locking the telescoping members at affixed length, and instead, allow some axial movement that tends to return to a given position. A first telescoping member  1704  includes a cap  1702  that can connect, for example, to an upper portion (e.g.  1608 ,  1610 ) of an assembly for towing a luggage case. The first telescoping member  1704  slides within a second telescoping member  1706  in a co-axial arrangement. An elastic member  1708  is coupled to the bottom  1710  of the cap  1702  at a first end, and to a fixed point  1712  at a second end in the second telescoping member  1706 . The elastic member  1708  can be an elastic cord, a spring, or similar member, and allows the first and second telescoping members  1704 ,  1706  to move relative to each other on the same axis, but also biases them to a neutral position. In this way if the user lurches or otherwise moves suddenly the elastic member can mitigate the shock to the luggage case by allowing some movement between the first and second telescoping members  1704 ,  1706 .
