FIELD OF THE INVENTION

The present invention relates to a suitcase which is convertible into a child carrying wheeled stroller. The sub-assembly forming the child carrying seat assembly is conveniently stored in the rear compartment of the suitcase when not in use, and may be extended into a use position by merely withdrawing the handle portion upwardly until a seat pivots into a seat position on the top portion of the suitcase and having a seatback carried between the tubular members and immediately rearward of and above the seat member.

BACKGROUND OF THE INVENTION

The present invention relates to a suitcase which is a convertible into a child carrying wheeled stroller assembly. It has become well established in the suitcase art field that it is desirable to have a suitcase which incorporates wheels at the bottom thereof, and a retractable handle located in a rear compartment of the suitcase. These features enable the user to easily extend the handle upwardly, and pulling backwardly on the suitcase, the suitcase then pivots onto its rear wheels and provides the user with an easy and convenient method of transporting the suitcase. This has been determined to be far more preferable than forcing the user to either use a shoulder strap or a handle for lifting the suitcase. In some cases, the wheels are retractable into concealed compartments on the underside of the suitcase, although this is not necessary for the efficient use of such a suitcase.
It has been observed, however, that for the traveling public which travels with children, such suitcases are convenient, and eliminates the need for carrying the suitcase, nevertheless, for those with young children, it is necessary to travel with a collapsible stroller as well as a suitcase. The present invention attempts to solve the problem of having parents carry a collapsible stroller by providing a suitcase which incorporates therein with compartments for carrying clothing, laptop computers and the like, but is further provided with a rear compartment which carries a sub-assembly movable between a retracted rest position, and an extended use position wherein a child carrying seat sub-assembly may be easily extended into a use position, utilizing the suitcase top as a support platform for the child carrying seat member. In this manner, the suitcase can function as a wheeled stroller and eliminates the requirement that parents traveling with young children carry a collapsible stroller as well as a suitcase. The present invention provides a convenient and easy to use suitcase convertible into a child stroller for easy transportation of the unit once the child is seated thereon, but nevertheless, is retractable into a rest position totally within the confines of a rear compartment of the suitcase.

DETAILED DESCRIPTION OF DRAWINGS

With particular reference to FIGS. 1 and 2 of the drawings, there is shown a suitcase 10 having general construction as is commonly known. The suitcase 10 includes a top 11, bottom 12, a rear wall 13, and a front 14. As is known with traveling suitcases in the present state of the art, the suitcase is provided with a first rear wheel 16 and a second rear wheel 18 to facilitate transporting the suitcase.
As is typical with suitcases intended for modern travel, the suitcase includes a plurality of compartments which is not particularly relevant to the present invention. However, the suitcase 10 of the present invention is shown to include a rear compartment 20 which is enclosed by means of a zipper 21. The rear compartment is shown to contain a child carrying seat sub-assembly 25, and as shown in FIGS. 1 and 2, is in its retracted rest position.
The seat sub-assembly 25 is carried within the rear compartment by means of an upper support bracket 27, and a lower support bracket 29, both of which are secured to the rear compartment by means of rivets 31 as shown. The upper and lower support brackets 27 and 29 respectively carry a pair of opposed vertical support tubes 33 and 35 respectively. Each of the vertical support tubes 33 and 35 are shown to accommodate a pair of opposed telescoping tubular members represented by the numerals 37 and 39 respectively. The top of the telescoping tubular members 37 and 39 are inter-connected by a handlebar 40. As is also shown in FIG. 3, a seat member 42 is mounted between the opposed telescoping tubular members 37 and 39 by means of a pair of pivot rods 43 and 44 respectively. As is shown in FIG. 4, when the telescoping tubular members 37 and 39 are fully extended, the seat member 42 will pivot downwardly into a use position resting on the top 11 of the suitcase 10. As is also shown in FIG. 3 of the drawings, a seatback 47 is mounted by a pair of mounting brackets 48 and 49 respectively, between the opposed telescoping tubular members 37 and 39.
It can be observed from FIGS. 2 and 3, that the suitcase in its normal position when being used as a suitcase will be in the position as illustrated in FIG. 2. In order to utilize the sub-assembly 25, the user would unzip the zipper 21, and grasp the handlebar from 40. By pulling up on the handlebar 40, the opposed telescoping tubular members 37 and 39 are raised to their fully extended position as shown in FIG. 3. This raises the seatback 47 to its use position, and brings the seat member 42 into a position above the top 11 of the suitcase 10. As shown in FIG. 4, the seat member 42 will automatically pivot downwardly and rest on the top 11 of the suitcase 10 which forms a support platform for the seat member 42. A user may then pivot the entire suitcase with the seat sub-assembly in its extended position downwardly onto the wheels 16 and 18 respectively, thus creating a two wheel stroller for a child.
As is further illustrated in FIG. 3, the telescoping tubular members 37 and 39 telescope completely into the rear compartment 20 as shown in FIG. 2. The seatback 47 remains affixed to a pair of the opposed tubular members 37 and 39, and the seat member 42 is merely pivoted upwardly incident to the retraction process such that it lays flat against the seatback 47 to accommodate the retraction of the entire assembly into the rear compartment 20.
As illustrated in FIG. 5, the suitcase is also provided with a pair of front stabilizer legs. As an optional feature, the stabilizer leg may include a spring-loaded outrigger leg 52. The outrigger leg 52 is designed to be coordinated with the stabilizer leg 50 such that the stabilizer leg 50 is provided with a spring-loaded latch 53 which is designed to extend the outrigger leg 52 when weight and pressure is pushed down onto the stabilizer leg 50, and to retract the outrigger leg 52 when the forward portion of the suitcase 10 is lifted off of the ground. The extended position of the outrigger leg is shown in FIG. 5A, while the retracted position is shown in FIG. 5B.
FIG. 6 illustrates a further picture which may be incorporated into the present invention, and simply discloses that the handlebar 40 may be included with a spring-loaded latch mechanism 55 which, upon depression of the spring-loaded latch 55, will actuate a pair of opposed latch catches 56 and 57 respectively in order to extend the telescoping tubular members upwardly when it is desired to place the sub-assembly in its use position. The latch assemblies of the type described herein are commonly known in the art and are employed in such extendable handle assemblies.
It is also contemplated by the present invention that the suitcase 10 may be designed with a pair of retractable forward front wheels retracted under the front wall 14 of the suitcase 10. This feature, when incorporated into the suitcase of the present invention, permits the suitcase to be converted to a 4-wheel stroller for further ease of use when carrying a child. It is contemplated that when this feature is incorporated in the suitcase, the front wheels when extended, would raise the level of the front wall 14 of the suitcase 10 slightly greater than the rear wheel 16 and 18 respectively. In this manner, when the device is being used to carry a child, the child will be tilted such that the child will be tilted slightly backward so the back of the child is well rested into the seatback.
It is also contemplated that the sub-assembly may further include child support straps for strapping the child to the seat once the sub-assembly has been extended to its use position and the child has been placed on the seat member and against the seat back.
While there has been disclosed what is at present considered to be the preferred embodiment of the invention, various improvements may be made hereto and incorporated into the invention. All such obvious modifications and variations are intended to be covered by the appended claims.
