## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to the field of infant products and more particularly to a novel device that is collapsible and mobile that can be converted into a stroller, a walker, a high chair, a carrier, a bassinet, and a backpack and that can also accommodate the infant car seats of third party manufacturers.
2. Description of the Prior Art
The field of multi-purpose infant products is a relatively crowded one. The advantages of having one device perform more than one function include the versatility involved, the space saving features and quite significantly, the cost savings. When providing necessities for babies, both space and funds can quickly be consumed.
Many of the devices found in the prior art related to combination infant products is bulky and limited to a relatively few number of uses. When a busy mobile parent or infant caretaker takes an infant on outings, to daycare or to visit relatives, many devices are desired to accommodate the infant's needs. These devices include: an infant car seat to keep the infant secure while driving, a stroller to walk the infant once at the destination, a walker to allow the infant to exercise his legs and find his way about, a high chair to feed the infant, a carrier to carry the baby into smaller spaces such as a restaurant, a bassinet in which the baby can nap and a backpack that holds the collapsed frame of the device, which can be attached to the back of the caretaker while carrying the baby by hand in the infant carrier for convenient and comfortable walking.
However, there is a major drawback to having to transport all of these devices, i.e., the amount of space required and the cumbersome aspects of moving the devices from the transport vehicle to the final destination. In the past, many combinations of various baby features have been utilized, with mixed results.
Some of these combinations include combination car seats and baby strollers (See U.S. Pat. No. DES345,720 to Pohl, U.S. Pat. No. DES358,058 to Anthony et al., U.S. Pat. No. DES402,235 to Haut, U.S. Pat. No. DES508,443 to Sanchez, U.S. Pat. No. 4,113,306 to von Wimmersperg, U.S. Pat. No. 4,762,256 to Whitaker, U.S. Pat. No. 5,230,523 to Wilhelm, U.S. Pat. No. 5,398,951 to Ryu, U.S. Pat. No. 5,662,339 to Svendsen et al., and U.S. Pat. No. 5,964,470 to Syendsen).
Other combinations have included a baby carrier/backpack combination (See U.S. Pat. No. DES365,925 to Roan), a scooter/walker/stroller (See U.S. Pat. No. 2,907,372 to Leger), a stroller/walker/carriage (See U.S. Pat. No. 3,079,162), a sleeper/walker/stroller (See U.S. Pat. No. 3,248,125 to Gill), a carrier/stroller/backpack/car seat (See U.S. Pat. No. 4,620,711 to Dick), a face-to-face carrier/diaper bag/changing surface/portable crib (See U.S. Pat. No. 5,333,769 to Skroski), a backpack/stroller, car seat/bed, chair (See U.S. Pat. No. 5,431,478 to Noonan), a dining chair/car seat/cradle/bed (See U.S. Pat. No. 5,478,096 to Ting), a bed/carrier/rocker (See U.S. Pat. No. 5,987,665 to Simantob et. al), a car seat/stroller/swing (See U.S. Pat. No. 6,250,654 to Willis), a car seat/rocker/stroller (See U.S. Pat. No. 6,910,696 to Bargery et. al), and a car seat/stroller/backpack (See U.S. Pat. App. US2003/0192925 to Boone).
None of the prior art provides the utility of combining the ability to load third party manufacturer car seats, plus the ability to collapse the device for storage and transport and having the ability to transport a stroller, a walker, a high chair, a carrier, a bassinet, and a backpack. By providing all of these devices in one, not only is the infant caretaker experiencing heightened convenience, but both space and money are conserved.
Accordingly, it is the objective of the present invention to overcome the shortcomings of the prior art and provide a multi-use baby device that saves both space and money while still providing the caretaker of the infant the versatility to fully accommodate the needs of the infant both at home and while traveling.

We turn now to the drawings for further clarification of the invention. The skeleton of the device 10 is outlined in FIGS. 1, 2, 3 and 4. The skeleton is collapsible for ease of transport and storage. The collapsibility of the device 10 is illustrated in FIGS. 3 and 4. In FIG. 1 the device 10 is in position to receive optional parts. In FIG. 2 the device has the central receiving piece 27 in an elevated position and the rear bars 15, 16 moved forward and attached to the front bars 17, 21 at a lowered position, thereby reducing the angle of the skeleton 10 for ease of use as a high chair. In FIG. 3 the collapsible joints 20, 24 are depressed and the first front bar 17 and the second front bar 21 are collapsing to ultimately be put in the collapsed position illustrated in FIG. 4.
The skeleton of the device 10 is comprised of a horizontal rear support bar 11 that connects a first wheel 12 and a second wheel 13. A first rear bar 15 and a second rear bar 16 are perpendicularly attached to the rear support bar 11, both rear bars 15, 16 being substantially vertical in position and substantially parallel to each other, each terminating in the handle 14. A first front bar 17 and a second front bar 21 extend from the handle 14 in a substantially angular orientation terminating in corresponding bottom portions 18, 22. The front bars 17, 21 are substantially parallel to each other. The corresponding bottom portions 18, 22 of the front bars 17, 21 are in a substantially vertical position and are parallel to each other.
The bottom portions 18, 22 of the front bars 17, 21 each terminate in a wheel 19, 23. Collapsible joints 20, 24 are located substantially midway down the front bars 17, 21. When the device 10 collapses, the top portions 31, 32 of the front bars that are located between the handle 14 and the collapsible joints 20, 24 fold down to lay flush with the bottom portions 33, 34 of the front bars 17, 21 located between the collapsible joints 20, 24 and the bottom portions 18, 22.
Between the front bars 17, 21 and the rear bars 15, 16 are a pair of side support bars 25, 26. A central receiving piece 27 is located between the front bars 17, 21. The central receiving piece 27 receives optional attachments for the use of the device 10. The central receiving piece 27 has a first side 28, a second side 29 and a bottom portion 30. The first and second sides 28, 29 are substantially parallel to each other and each side 28, 29 is connected to a corresponding front bar 17, 21. The bottom portion 30 is perpendicular to both sides 28, 29.

The infant seat 35 has an outer frame 36, a securing means 37, a backrest, 38, a seat portion 39, a first cushioning means 40 on the backrest 38 and a second cushioning means 41 for the seat portion 39. FIG. 1D shows the seat 35 with an optional carrying handle 42 so that the seat 35 can be removed from the skeleton of the device 10 and used as a baby carrier. The central receiving pieces 28, 29 attach to a first and second attachment means 54, 55 found on the backpack 43. When utilized this way, the infant seat 35 is carried by hand.
Alternatively, as shown in FIG. 1G, the infant seat 35 is attachable to the backpack 43 at the attachment means 54, 55 to the infant seat 35. When utilized in this manner, the skeleton of the device 10 is either carried by hand or stored in a convenient location for future use.
In FIG. 1C the infant seat is modified for use as a walker. In the seat 39 portion of the infant seat 35 are two openings 47, 48 for the child's feet to dangle below the seat 35 and reach the floor for use in walking around. FIG. 1E shows how the infant seat 35 can be removed from the skeleton of the device 10 attached to the backpack 43. The backpack 43 has an attaching means 44 for attachment to the back of an adult, a pair of straps 45 and a soft padding material 46 located between the straps 45 and the attachment means 44 on the backpack 43. The collapsed skeleton 10 is then carried on an adult's back and the infant seat 35 is carried by hand.
FIG. 1A shows the adjustable subframe 49 that can be added to the skeleton of the device 10. The subframe 49 has and outside frame 50, a first side attachment means 51 and a second side attachment means 52. Once received by the central receiving piece 37, the subframe 49 can then receive a bassinet 53 as illustrated in FIG. 1F.
Not shown in the drawings, but another aspect of the invention is the fact that an infant car seat, produced by a third party manufacturer, can be attached to the central receiving piece 27 with modifications made to the device 10 as necessary.
