BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates to mobile transport devices and, more particularly, to a device for transporting strollers between remote locations.
2. Prior Art
It is well known that the conventional baby cart is manually pushed forward or back, and mainly used outdoors in terrain of varying degrees. Normally, a person who fosters her baby (still in infancy and not walking) at home carries it or places it in a bed or cradle so that the person can do chores or other work.
Carrying a baby on the back often hinders the operations of one's extremities. A baby placed in a stationary bed or cradle will feel lonely and cry before long. Even if it is placed in a powered cradle with a regular swing, it often feels insecure and may cry after a while.
In view of the above, a need remains for a device for transporting strollers between remote locations so that a parent can be free to do work and still monitor the baby without having to physically push a stroller.
BRIEF SUMMARY OF THE INVENTION
In view of the foregoing background, it is therefore an object of the present invention to provide a device for transporting baby strollers. These and other objects, features, and advantages of the present invention are provided by a baby stroller transport device for selectively controlling the movement of a baby stroller.

Like numbers refer to like elements throughout the figures and prime and double prime numbers refer to alternate embodiments of such elements.
The device of this invention is referred to generally in FIGS. 1–8 by the reference numeral 10 and is intended to provide a device for transporting strollers. It should be understood that the device 10 may be used to transport many different types of objects and should not be limited to only strollers.
Initially referring to FIGS. 1 and 2, the device 10 includes a base member 20 having front 21 and rear 22 portions and a substantially planar top surface 23 provided with a centrally disposed longitudinal axis (not shown). The base member 20 further has a plurality of sidewalls 24 integral therewith and extending upwardly therefrom. The base member 20 is provided with a plurality of compartments 25 oppositely spaced from the axis and includes a port 26 disposed adjacent select ones of the plurality of compartments 25 and electrically coupled thereto for receiving a plug 27, as shown in FIG. 5, for re-charging a battery. The compartments 25 protect a battery from the weather in an external environment, thereby prolonging battery life.
Now referring to FIG. 3, the device 10 further includes a plurality of wheels 28 for supporting the base member 20 above a ground surface and for assisting in the movement of the device 10 between remote locations during operating conditions. The wheels 28 are preferably pneumatic tires for traversing uneven terrain and providing a smooth ride for the stroller, but may be other rubber wheels as commonly known in the industry. Two such wheels 28 are mounted adjacent the rear portion 22 and another wheel 28 is spaced therefrom adjacent the front portion 21. Such a wheel 28 is pivotally mounted to the base member 20 for being swiveled between select directions so that a user can effectively guide the device 10 along a non-linear path. The swiveling action gives the device 10 a short turning radius, enabling a user to maneuver the present invention in tight locations.
Now referring back to FIGS. 1 and 2, a plurality of elongated straps 29 having opposed end portions 30 are secured to the top surface 23 and to a stroller positioned thereon, respectively, so that the stroller can be maintained at a substantially stable position during operating conditions.

The device 10 fulfills a need for a self-propelled stroller transporter that is operable by a remote control. The device 10 is easy to use and saves parents and other adult caretakers from the fatigue associated with pushing traditional strollers. The device 10 is ideal for walks around the neighborhood or on trips to the mall or zoo. Instead of struggling to push a child in a stroller on grass, gravel or inclines, a parent can use this battery-powered device by remote control. The device 10 would be especially appealing to grandparents and females with limited upper body strength or other physical limitations and is also useful when the caretaker needs to use his/her hands for other chores.
While the invention has been described with respect to a certain specific embodiment, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention. It is intended, therefore, by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention.
In particular, with respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the present invention may include variations in size, materials, shape, form, function and manner of operation. The assembly and use of the present invention are deemed readily apparent and obvious to one skilled in the art.
