Abstract

The handle (16) for a luggage case (10) has two end portions (18, 20) and a rigid portion extending substantially across the top side (12) of the case (10) between two ends (44, 46) of the top side (12) when in a first position. One end (18) of the handle (16) is pivotably attached to one end (46) of the top side (12) of the case (10). The other end (20) of the handle (16) is securable to the other end (44) of the top side (12) of the case (10). When the handle (16) is in a first position it enables a user to lift and carry the case (10). The securable end (20) of the handle (16) may also be released and positioned at substantially greater distance from the case (10) than the other end (18) for engagement by a user for dragging the case (10) along the ground while allowing the user to maintain a relatively upright position. Wheels (36, 38) attached to the case (10) define a plane along the ground.

Description

LUGGAGE HANDLE BACKGROUND OF THE INVENTION The present invention relates to a luggage handle, and more particularly, a luggage handle arrangement which can be used to either carry or drag a luggage case.

Conventional luggage handle arrangements include C-shaped lift handles which are used to lift and carry a lug¬ gage case. In addition, various pull handles have been developed to allow a user to drag the luggage case along the ground while allowing the user to maintain a relatively uprig position. Such conventional handles include flexible straps and rigid rods which are attached to the luggage case and use to pull the luggage case along the ground on two wheels which are attached to one edge of the luggage case so that the lug¬ gage case is pulled in an upended fashion like a wheelbarrow.

Such conventional pull handle arrangements have cre ated difficulties in maintaining control over the direction a stability of the luggage case in transport. In addition, con ventional arrangements using a rigid handle do not provide an adequate manner in which the handle can be stowed and protect while allowing the handle to be long enough to allow the user to maintain a relatively upright position.

Accordingly, it is an object of the present inventi to provide a luggage handle which allows one to maintain con¬ trol over the direction and stability of a luggage case in transport.

It is another object of the present invention to pr vide a rigid handle for dragging a luggage case which provide an adequate manner in which the handle can be stowed and pro¬ tected while allowing the handle to be long enough to allow t user to maintain a relatively upright position.

Additional objects and advantages of the invention will be set forth in the description which follows, and in pa will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instru¬ mentalities and combinations particularly pointed out in the appended claims.

This application is related to U.S. Patent Application Serial No. 023,008 for LUGGAGE WHEEL ASSEMBLY by Ronald Louis Krenzel filed concurrently with this application and incorporated herein by reference.

SUMMARY OF THE INVENTION

To achieve the foregoing objects, and in accordance with the purposes of the invention as embodied and broadly described herein, there is provided luggage comprising case means for containing articles and handle means attached to the case means for manual engagement by a user to transport the case means . The handle means includes two end portions and is rigid intermediate the two end portions. The handle means is movably positionable both in a first position in which both end portions of the handle means are positioned relatively proxi¬ mate to the case means for enabling a user to manually engage the handle means to lift and carry the case means, and in a second position in which one end portion of the handle means is positioned proximate to the case means and the other end por¬ tion of the handle means is positioned at a substantially greater distance from the case means for enabling a user to manually engage said other end portion of the handle means to drag the case means along the ground while allowing the user to maintain a relatively upright position.

DESCRIPTION OF THE PREFERRED EMBODIMENT Reference will now be made in detail to the present preferred embodiments of the invention as illustrated in the accompanying drawings.

In accordance with the present invention there is provided luggage comprising case means for containing articles and handle means attached to the case means for manual engage¬ ment by a user to transport the case means. The handle means includes two end portions and is rigid intermediate the two end portions. The handle means is movably positionable both in a first position in vv-hich both end portions of the handle means are positioned relatively proximate to the case means for enabling a user to manually engage the handle means to lift and carry the case means, and in a second position in which one end portion of the handle means is positioned proximate to the case means and the other end portion of the handle means is posi¬ tioned at a substantially greater distance from the case means for enabling a user to manually engage said other end portion of the handle means to drag the case means along the ground while allowing the user to maintain a relatively upright posi¬ tion.

In accordance with the present invention there is provided luggage comprising case means for containing articles. As shown in Figs. 1 and 2, the case means includes luggage case 10 which is a right rectangular container. Luggage case 10 has six surfaces including a top side 12 front side 13 bottom side 14 and rear side 15. Case 10 made be opened and closed in any conventional way to allow access to the inside of case 10.

According to the present invention, there is also provided handle means attached to the case means for manual engagement by a user to transport the case means . The handle

SUBSTITUTE SHEET means has two end portions and is rigid intermediate the two end portions.

As shown in Fig. 1, the handle means includes a han¬ dle 16 which is sufficient rigid to maintain its original con¬ figuration in all operating positions. Rigid handle 16 is formed as a rigid tube or strip of plastic metal and includes two end portions 18 and 20 and is rigid intermediate the two end portions . Rigid handle 16 includes a convexly curved mid¬ dle portion 19 for enabling a user to grasp middle portion 19 when rigid handle 16 is in the position shown in solid lines.

According to the present invention, the handle means is movably positionable in a first position in which both end portions of the handle means are positioned relatively proxi¬ mate to the case for enabling a sure to manually engage the handle means to lift and carry the case means.

As embodied in Fig. 1, the first position of handle means is shown in solid lines. Both end portions 18 and 20 of handle 16 are positioned proximate to case 10 and are attached to case 10. This allows a user to manually engage handle 16 to lift and carry case 10. A grip 22 is positioned on handle 15 at an area around the central portion of top side 12 for user comfort.

According to the present invention, the handle means is movably positionable from the first position to a second position. In the second position, one end portion of the han¬ dle means is positioned proximate to the case means and the other end portion of the handle means is positioned at a sub¬ stantially greater distance from the case means for enabling a user to manually engage said other end portion of the handle means to drag the case means along the ground while allowing the user to maintain a relatively upright position.

As shown in Fig. 1, the second position of handle means is shown in broken lines. One end portion 18 of handle 16 is positioned proximate and affixed to case 10. The other end portion 20 of handle 16 is positioned at a substantially greater distance from case 10 so that it extends upward and outward from top side 12 and front side 13 of case 10. Becaus end portion 20 of handle 15 is designed to extend sufficiently

SUBSTITUTE SHEET upward, the user can manually engage end portion 20 without stooping and can maintain a relatively upright position when pulling case 10 along the ground.

In such fashion, handle 16 can be seen to be usable in two positions or two different methods of transporting case 10. The handle 16 has a rigid construction and is connected to case 10 for providing stability and control of case 10 in transport when dragging case 10 along the ground. Handle 16 creates no storage or protection problem when not used in the dragging position because it is secured in position as a handle by which case 10 may be lifted and carried.

It is preferable that the luggage include means attached to said one end of the handle means and the case means for pivoting the handle means about said one end of the handle means. Currently there are two preferred arrangements for the pivoting means. One is a swivel means, and the other is a hinged means.

In the arrangement including the swivel means, it is preferable that the pivoting means include swivel means for allowing rotation about the swivel means in more than one rota¬ tional degree of freedom, and also that the swivel means com¬ prises a ball joint. As shown in Figs. 3 and 7, the pivoting means which includes swivel means is a ball joint 24a in which one portion of the ball joint is connected to end portion 18a and the other part of ball joint 24a is affixed to top side 12a of case 10a. As a result, ball joint 24a allows handle 16a to move in more than more rotational degree of freedom so that it can move in a front to rear direction as well as in a lateral direction while otherwise maintaining a rigid connection between rigid handle 16a and case 10a.

In the alternative arrangement in which the pivoting means include hinge means, the hinge means allow rotation about the hinmeans in only one horizontal laterally extending axis of rotation when the luggage is oriented so that the handle means is on the top of the case means.

As shown in Figs. 1 and 5, the hinge means include a hinge 26 having a pintle 28 which extends along a horizontal laterally extending axis of rotation 30. One part of hinge 26

SUBSTITUTE SHEET iss attached to end portion 18 of handle 16, and the other part of hinge 26 is attached to case 10. As a result, rigid handle 16 pivots about horizontal laterally extending axis 30 so that rigid handle 16 and case 10 is even more rigid than the connec¬ tion shown in Fig. 3, in which the pivot means is a swivel means. As a result, the arrangement shown in Fig. 1 allows the user additional control over the lateral stability of case 10.

It is preferable that the luggage include wheel means attached to the case means for enabling the case means to roll on the ground on said wheel means when the handle means is in the second position and when the user drags the case means. As shown in Figs. 3 and 4, the wheel means include four wheels including two caster wheels 32a positioned in the front corners of bottom side 14a of case 10a and two other wheels 34a posi¬ tioned in the rear corners of bottom side 14a of case 10a.

For certain applications it may be preferable to have at least four wheels attached to the case means and defining a plane for enabling the case to roll on the ground on said at least four wheels when the handle means is in the second posi¬ tion and when the user drags the case means. As shown in Figs. 3 and 4, the wheel means include four wheels, wheel pairs 32a and 43a, in which the bottom surfaces of these wheels define a plane which is coincident with the plane of the ground to enable case 10 to roll on the ground on those four wheels. The rigidity of handle 16a and the connection between handle 16a and case 10a allows sufficient control and stability of case 10a when dragged by a user so that the four wheels engage the ground during transport.

For certain applications it may be preferable to have three wheels attached to the case means which define a plane for enabling the case means to roll on the ground on said three wheels when the handle means in the second position and when the user drags the case means. It is further preferable that two of the three wheels are positioned at a trailing end of the case means and the third wheel is a caster positioned at a trailing end of the case means and the third wheel is a caster positioned at a leading end of the case means. As shown in Figs. 1 and 2, the three wheels include front wheel 36, which is a caster mounted in the middle of bot tom side 14 toward the front side 13 of case 10, and the other two wheels are positioned on the bottom side 14 toward the rea side 15 of the case 10 at corner positions. Skids 40 are posi¬ tioned at the front corners of the bottom side 14 of case 10 t provide additional lateral stability in the event case 10 tips in a lateral fashion.

It is preferable that the luggage include means for selectively securing the other end portion of the handle means to the case means when the handle means is in the first posi¬ tion and for releasing the other end portion of the handle means from the case means to permit the handle means to be repositioned in the second position.

As shown in Figs. 1 and 6, the means for selectively securing the other end portion of the handle means to the case means includes spring clip 40 which is attached to end portion 20 of handle 16, and anchor loop 42 which is affixed to the top surface 12 of case 10. Spring clip 40 snaps into anchor loop 42 to secure it to anchor loop 42 and secure handle 16 to case 10 in the first position shown in solid lines. Spring clip 40 can be opened and released from anchor loop 42 to allow handle 16 to pivot and assume the second position shown in broken lines.

It is preferable that the case means include a top side having two ends and the handle means extend substantially across said top side between the two ends of said top side.

As shown in Fig. 1, the top side of the case means is top side 12 having two ends 44 and 46 proximate to front side 13 and rear side 15. Rigid handle 16 extends substantially across top side 12 between ends 44 and 46 of top side 12. Due to the geometry of the arrangement and the existence of the luggage having various size cases, it is envisioned that larger and longer size luggage may require handle 16 to have a lesser extent relative to the top surface 12 of luggage case 10 than that shown in Figs. 1 and 3 so that rigid handle 15 is a conve¬ nient length for dragging case 10.

SUBSTITUTE SHEET Elements shown in the embodiments of Figs. 3 and 4 having identical numerals to those in the embodiment shown in Figs. 1 and 2 have structure and function similar to that described in relation to the embodiment shown in Figs. 1 and 2.

Additional advantages and modifications will readily occur to those skilled in the art. The invention in its broader aspects is, therefore, not limited to the specific details, representative apparatus and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the general inventive concepts as defined by the appended claims and their equivalents.
