This application claims priority to provisional application No. 60/682,222, filed May 17, 2005, the disclosure of which is incorporated by reference herein and made a part of this application.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to devices for releasably attaching a carry bag, or item of luggage, onto the handle system of another carry bag or wheeled cart having upright supports. In particular, the present invention relates to a rotating handle for accomplishing such attachment objective, and a carry bag system having such rotating handle.
2. Description of the Related Art
Present day carry bags such as items of luggage with extendible tubular handles, or carry carts with such extendable handles generally utilize elastic ties such as bungee style resilient expandable cords with hooks or clips to attach a bag to the handle system. In general, such attachment systems are supplied separate from the carry bag or related handle and are somewhat cumbersome to utilize, since they often require strategic placement of the attachment devices and hooks to secure the bag in place. In addition, placement of the expandable cords often involves stretching the cords, a procedure which can sometimes be dangerous in that the cord can be accidentally released and cause injury.
At present, a convenient system for attaching items of luggage together or to transport devices such as luggage carts has not been developed.
SUMMARY OF THE INVENTION
The present invention relates to a rotatable handle system which is resiliently attached to an item of luggage such as a carry bag, and which is adapted to be quickly manipulated in a manner to releasably attach the bag to the handle system of another such carry bag, or to a wheeled carry cart.

The handle preferably has a generally elongated configuration, and preferably may be rectangular or oval in configuration. However, any elongated shape will suffice.
The device for resiliently attaching the handle to the first carry bag can be at least one resilient member attached at one end to the handle, and at the other end to the second carry bag. Alternatively, the handle may be resiliently attached to the second carry bag by a plurality of resilient members. Still alternatively, the handle may be resiliently attached to the first carry bag by at least two resilient woven straps, each strap being attached at one end to a wall of the second carry bag, and at the other end to the handle by a device which permits rotation of the handle relative to the strap or straps.
The handle may also be resiliently attached to the first carry bag by at least two resilient bungee cords, each cord attached at one end to a rear wall of the second carry bag, and at the other end to the handle by a device which permits rotation of the handle relative to the bungee cords. Further, the handle may be resiliently attached to the first carry bag by at least four resilient bungee cords, each cord is attached at one end to a rear wall of the first carry bag, and at the other end to the handle by a device which permits rotation of the handle relative to the bungee cords.
The handle may further comprise a gripping handle attached thereto to facilitate manually moving the handle between the storage position and the position in engagement with the support members. Also, the handle may be configured as a pouch for carrying articles, and at least one side of the handle may include a plate member for engagement with the support members. Preferably, the pouch and the plate member are generally rectangular or oval in shape. Any shape is preferred, provided that the handle interferes with the upright supports when positioned in the attaching orientation. The pouch preferably includes a zipper closure for opening and closing the pouch position.
Preferably the plate member is generally planar and is made of metal or plastic. Further, the plate member preferably includes cutout portions shaped generally similar to the outer surfaces of the support members for complementary engagement therewith.
In particular, the invention relates to a system for releasably attaching an article of luggage such as a first carry bag to a second carry bag system or to a wheeled luggage cart having at least a pair of spaced upright support members, when the first carry bag is positioned atop the second carry bag, which comprises a handle dimensioned in at least one direction to interfere with and engage the support members when positioned thereagainst in at least one predetermined orientation generally transverse to the support members. A device is provided for resiliently attaching the handle to the first carry bag in a manner to permit storage of the handle in a first position and to facilitate resilient movement of the handle away from the first bag, and permit rotation of the handle between the first storage position and the at least one predetermined orientation such that when the handle is retracted toward the first carry bag, the handle engages the support members of the second carry bag system to thereby engageably attach the first carry bag to the upright support members of the second carry bag system.
The system preferably comprises a handle having a generally elongated configuration, and a device for resiliently attaching the handle to the first carry bag in a manner to permit rotation of the handle between a first storage position and a second interference position with the upright support members of the second carry bag system to thereby permit attachment of the second carry bag to the upright support members of the second carry bag system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring initially to FIG. 1 there is shown a bag 10 having mounted thereto an extendible handle system having a pair of parallel tubular supports 12,14 connected by gripping handle 16 and extendible to the position shown in FIG. 3.
Rotatable attachment handle 18 is attached to the rear wall 19 of bag 20 via resilient connectors 22,24 to permit resilient movement of handle 18 rearwardly away from bag 20 by grasping gripping handle 23. Since attachment handle 18 is actually rotatably attached to resilient connectors 22,24 (i.e., resilient woven straps) by a rivet or other fastener as will be described hereinbelow, the handle 18 readily be selectively rotated to either a horizontal attachment position, or the vertical storage position as shown. Handle 18 may be configured as a pouch, or pocket, having zipper 21, which permits access to the inner storage area for storing articles or the like.
Handle 18 is formed as a pocket or pouch 18a as shown, and includes a planar member such as plate 25 intended for direct engagement with tubular supports 14, 12 as will be described hereinbelow. Plate 25 may be made of plastic, metal or the like, and is configured to have at least one dimension which is sufficient to cause it to interface with upright tubular supports 14, 12 when it is positioned thereagainst in transverse relation thereto. In the embodiment shown, the plate 25 is rectangular. Pocket 18a may optionally be the same size as plate 25 as shown, or it may be of lesser or greater dimensions. However, the combination of pocket 18a and plate 25 is considered to be handle 18 for the purpose of the present description.
Referring to FIG. 3 there is shown a second carry bag system 26 identical to carry bag system 10 of FIG. 1, except that the first carry bag system is attached to the parallel tubular supports 14, 12 by first extending the rotatable handle 28 rearwardly away from carry bag 27, and then rotating it to a horizontal interference position between the tubes.
Thereafter, the handle 28 is released to permit the resilient members 30, 32 to draw the handle 28 forwardly toward the parallel tubular supports 14, 12 to complete the attachment of the first bag system 26 to the second bag system 10. Axle, wheel and bag support system 43 is provided to permit moving the carry bags 20, 27 from place to place.
Referring now to FIG. 4 there is shown an alternative embodiment of the present invention wherein a carry bag system 34 includes parallel tubular-type upright support members 36, 38 connected by gripping handle 37. Rotatable handle 40 is attached to the rear portion of the carry bag 42 via resilient elastic members 44, 46 as shown in FIG. 5.
As shown in FIGS. 4-6, the rotatable handle is in the form of a relative narrow plate 48 having a gripping handle 50 suitably attached thereto for gripping and withdrawing the rotatable handle rearwardly of the carry bag for releasable attachment purposes as described previously. The handle is rotatably attached to the resilient members by a rivet or other fastener as will be described hereinbelow.
In the embodiment of FIGS. 4-6, the rotatable plate 40 and handle 50 is rotatably attached to resilient fabric-type (i.e., resilient woven straps) connectors 44, 46 which are attached to the carry bag by stitching or otherwise at one end, and to the plate 40 at the other end by a rivet or other fastener arrangement which permits handle rotation, utilizing a plate or leather base as a connector. The sequence of operation of attachment of carry bag 34 to the carry bag system 42 shown in FIGS. 4-6 is self evident and identical to that described in connection with the previous embodiments. Wheel system 43 is provided to permit movement of the carry bags 34 and 42 together as a single unit when attached as described herein.
Referring now to FIGS. 7 and 8, there is shown another preferred embodiment of the rotatable handle 60 of the present invention attached to carry bag 62 by four resilient single bungee (i.e., non-metal elasticized rubber) connectors (or cords) 64. Alternatively, rather than using four cords as shown, the handle may be attached by one or two of such cords (not shown), but in the same manner as is shown. The handle 60 has gripping handle 66 attached by rivets or other fasteners 68 as shown, and may be in the form of a strap, a molded grip, or a section of rope. Tubular supports 72, 74, 71, 75 are connected by gripping handles 37 and 73, respectively, as shown in FIGS. 7 and 8.
In operation the carry bag 62 is first positioned atop the lower carry bag 70 shown in phantom lines over lower support shelf 73 for illustration purposes, and thereafter the user grips handle 60 via gripping handle 66, and it extends rearwardly of the carry bag as shown. Although the handle 60 can be configured in a variety of shapes, in general, it should be dimensioned sufficiently narrow in one direction to fit between the upright tubular supports 72,74,71,75 when in the stored position, and of sufficient length in at least one other direction to interfere with the tubular supports 72,74 when it is rotated, preferably 90 degrees to the position of interference with tubular supports 72, 74 as shown in FIG. 8. Thereafter the handle 60 is slowly released to permit bungee cords 64 to withdraw the handle 60 toward the carry bag 62 to engage tubular supports 72, 74 to complete the attachment of carry bag 62 to the carry bag 70 and associated supports 72, 74. Carry bag 62 has its own system of tubular supports 71, 75 and wheels 77 for use with another bag system in the same manner, and for transporting carry bag 62, respectively. It can be seen that the handle can be rectangular, oval or any alternative generally elongated shape, provided that it will interfere with the supports when in the attachment position. Preferably the handle has a transverse (or widthwise) dimension that enables it to fit between the upright supports when in the stored position, and it will interfere with the supports when in the attachment position.
Referring now to FIG. 9 there is shown the preferred single bungee cord connecting system 80 for the embodiment of FIGS. 7 and 8. Similar arrangements can be utilized for the embodiments of FIGS. 1-6.

It should be understood that the single bungee cords of the embodiment of FIGS. 9-12 can be substituted by double or triple bungee cords, not shown. In addition, the present invention can be incorporated in carry bags having their own tubular supports, or carry bags having no tubular supports, but releasably attachable to carry bags or wheeled carts with tubular supports.
Referring now to FIGS. 13 and 14, there is shown another alternative embodiment of the present invention, having handle 100 rotatably attached to a carry bag 102 (shown in FIG. 14) by resilient spring metal connectors 104. The handle 100 which may be of molded polymeric material includes hand grip 106 as shown, and is connected to spring metal connectors 104 via rivet 108 or other suitable fastening device. Spring metal connectors 104 are in turn connected to the carry bag 102 via end attachment devices 103 which are attached to bag 102 as shown in FIG. 14.
FIG. 14 shows the rotatable handle system of FIG. 13 in position withdrawn away from the rear wall of the carry bag 102 in position or prior to rotation to an interference position with upright supports associated with another carry bag as shown in and described in connection with the previous views.
FIG. 15 is a bottom view of the handle system shown in FIGS. 13 and 14.
FIGS. 16-18 illustrate an embodiment of the invention wherein handle 118 is formed only as a generally planar plate member 125 having handle grip 123 attached thereto. Plate member 125 has cutout portions 126, 128, 130, 132 at each end as shown to permit plate member 125 to conform to the outer shape of upright support members 114, 116 as shown in FIGS. 17 and 18 to lock into position by interference relation with the support members as shown at 126a, 128a, 130a and 132a. For example, if the upright support members have square or rectangular cross-sections as shown, cutouts 126, 128, 130, 132 and bent ends 134,136 may be made to be square, to complement the outer surfaces of the support members and snap into position as shown. Alternatively, if the upright support members have another outer shape (i.e., circular), then the cutouts will be correspondingly shaped to conform the handle at each end to the shape of the upright support members and the bent ends can be arcuate to provide complementary locking engagement therewith and substantial surface contact therebetween.
It should be understood that in each of the embodiments described hereinabove, the rotatable handle can be made of a polymeric molded material preferably covered by the same fabric as the carry bag. The manual gripping handle can be made of a flexible material or it can be made of a fabric strap or leather strap or rope that matches the carry bag. Alternatively the grip may be a leather strap as well. The rotatable handle can also be made of metal with or without fabric covering.
In addition, the carry bag of the present invention can be releasably attached to the well known wheeled luggage carts having upright supports in the same manner as described hereinabove.
It should be understood that the various features shown and described hereinabove, can be varied from embodiment to embodiment, utilizing features of one of the embodiments with features of the other embodiments and vice a versa, so as to provide various combinations of features in the rotatable handle system for attaching a first carry bag system to a second carry bag system, wheeled luggage cart and the like.
