Slip resistant stationary baby walker
A stationary baby walker including a slip resistant mat upon which a baby may practice walking.
The present invention generally relates to baby walkers, and more particularly to a stationary baby walker with a slip resistant mat allowing a child to safely practice walking.
BACKGROUND OF THE INVENTIONBaby walkers are used to allow children to safely practice walking. Such walkers may be comprised of a mobile structure. A child may freely move about via this structure while practicing walking. Known prior art of this design is typified by U.S. Pat. No. 4,773,639 (filed May 13, 1987).
A disadvantage of baby walkers comprised of a mobile structure is the uncertainty of where the child may take the structure. There is a substantial risk that the child may roam off in the walker. Worse still is the possibility that a child may maneuver over an edge, namely the edge of a set of stairs, and get injured. If a child maneuvers over an edge of a set of stairs, the child may either fall out of the walker or the child may fall while remaining in the walker.
An estimated 8800 children under the age of 15 months were treated in hospital emergency rooms in 1999 for injuries associated with the use of mobile infant walkers. Committee on Injury and Poison Prevention, Injuries Associated with Infant Walkers, Pediatrics, Vol. 108, No. 3, September 2001, at 790. In fact, between 1973 and 1998, thirty four deaths associated with the use of mobile infant walkers were reported to the U.S. Consumer Product Safety Commission. Stairs were implicated in as many as 96% of cases of infant falls, either falls from the mobile walker or falls with the infant remaining in the mobile walker. Stairs were also implicated in almost every case resulting in severe injuries.
To avoid these problems, baby walkers may alternatively be comprised of a fixed stationary frame with a mobile inner component. Walkers of this variety allow a child to practice walking by moving about in a finite space while supported on a mobile seat. Known prior art of this design is typified by U.S. Pat. No. 6,001,047 (filed Mar. 5, 1998).
A disadvantage of baby walkers comprised of a fixed stationary frame with a mobile inner component is the requirement that such a device be placed on a surface which provides the child traction (e.g., carpet). If the unit is placed on a low friction surface (e.g., linoleum), the child will be unable to practice walking due to lack of traction.
SUMMARY OF THE INVENTIONThe present invention provides a stationary walker including a frame, a movable inner seat, and a slip resistant mat on which a child may walk. The stationary walker may be placed on any surface, including slippery surfaces (e.g., linoleum), and still the child may practice walking. The slip resistant mat will also help keep the child's feet clean even if the stationary walker is placed, for instance, outside on grass or dirt.
In one embodiment of the invention, a stationary baby walker having a horizontally oriented rectangular upper frame including a rail system is provided. At a horizontal plane below the level of the horizontally oriented rectangular upper extent, but above the level of the floor, a slip resistant mat is located. This slip resistant mat encompasses substantially the entire surface area below the vertical projections of the inner or outer edges of the horizontally oriented rectangular upper extent. The slip resistant mat may also encompass some other area. The mat is designed to provide traction for the child. A child may thus utilize the stationary walker and practice walking independent of the surface upon which the walker is placed.
A plurality of interchangeable toys may be provided to encourage the child to walk back and forth in the stationary walker. These toys may include teethers which massage the gums, toys with mirrors, and even simple electronic devices which light up or make noise. These interchangeable toys may be removably affixed to the frame.
The above mentioned and other features of this invention, and the manner of attaining them, will become more apparent and the invention itself will be better understood by reference to the following description of embodiments of the invention taken in conjunction with the accompanying drawings.
Corresponding reference characters indicate corresponding parts throughout the views.

The at least one wheel 710 is rotably connected to an axle 726. The axle is connected to a first substantially vertical member 728 extending down through the slot 724. The first substantially vertical member 728 is connected to a substantially horizontal member 730 which is also connected to a second substantially vertical member 732. The second substantially vertical member 732 is connected to the seat assembly 130.
The at least one wheel 710 operates within the hollow interior 722 of the side bar 118′. The at least one wheel 710 rests vertically on the upper face of at least one of the first lower substantially horizontal wall 718 and the second lower substantially horizontal wall 720. The side bar 118′ rests vertically on at least one of the plurality of supports 116 such that the at least one of the plurality of supports 116 do not obstruct the slot 724, first substantially vertical member 728, or substantially horizontal member 732. This arrangement reduces the possibility of a child pinching its fingers due to the difficulty of a child reaching down, under, and back up into, the slot 724.

The interchangeable toys 126 are placed in the toy holders 124 by aligning the plurality of clips 912 with the recesses 918 of the toy holder 124. Because the inner walls 920 of the toy holder are angled, as are the contours of the protrusions 914 and the clips 912, downward force applied to the top of the toy base 910 will secure the interchangeable toy 126 in the toy holder 124 because the protrusions 914 fit into the recesses 918 near the bottom of the cavity 916 of the toy holder 124.
The interchangeable toys 126 are removed from the toy holders 124 by compressing the plurality of clips 912 towards each other. This causes the small protrusions 914 to move towards each other, away from the inner walls 920 of the toy holder 124. While the clips 912 remain compressed, and the protrusions 914 are free of the recesses 918 in the cavity 916 of the toy holder 124, the interchangeable toy 126 may be extracted from the toy holder 124. It should be remembered that the plurality of clips 912 are resilient such that after being compressed, and subsequently released, they return to their original positions.

The interchangeable toy 126′ is placed in the toy holder 124′ by applying downward force to the top of the toy base 910′. Because the inner walls 920′ of the toy holder are angled, as are the contours of the toy base 910′, the interchangeable toy 126′ simply slides into place. The magnet 1010 is attracted to the complementary magnet 1012, thus securing the interchangeable toy 126′ in the toy holder 124′.
The interchangeable toy 126′ is removed from the toy holder 124′ by applying an upward force, away from the toy holder 124′. This force need only be large enough to break the magnetic bond between the magnet 1010 and the complementary magnet 1012. Ideally, the magnet 1010 and complementary magnet 1012 form a magnetic bond strong enough to prevent a baby or toddler from removing the interchangeable toy 126′, but weak enough for an adult to remove the interchangeable toy 126′.

The stationary walker of the present invention is used by placing a child in the baby seat 134. While in the baby seat 134, the child may play with the interchangeable toys 126 at one end of the walker. The child may then turn around in the baby seat 134, which is configured to rotate within the seat assembly 130, and proceed to walk down the length of the stationary walker. While walking, the child is supported in the baby seat 134 which, in turn, is supported by the baby seat support 1110 and the seat assembly 130 resting on the rails 122 affixed to the side bars 118 of the upper structure 112. While walking down the length of the stationary walker, the child is unlikely to slip because the slip resistant mat 128 provides the child with traction. Even when the stationary walker is placed on a slippery surface, the child will be assured of traction on the slip resistant mat 128. Upon reaching the opposite end of the stationary walker, the child may play with some of the interchangeable toys 126 located there. Again, the child may rotate within the walker by turning in the baby seat 134, which is configured to rotate within the seat assembly 130. Once rotated, the child may safely walk back to the original location.
While this invention has been described as having an exemplary design, the present invention may be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known of customary practice in the art to which this invention pertains.
