Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved suspendable child walker systems embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
Specifically, it will be noted in FIGS. 1 through 6, that there is provided a new and improved suspendable child walker system 10. The suspendable child walker system 10, in its broadest context, comprises a ceiling slide bar 12, a roller assembly 14, a spring 16, a child seat 18 and a support harness 20.
More specifically, the ceiling slide bar 12 is formed as a hollow, generally rectangular box. The slide bar has a roof 22 and a floor 24 with short vertical sidewalls 26 connecting the roof 22 and floor 24. The roof 22 and floor 24 have parallel long sides 28 and parallel short sides 30 and includes a plurality of circular apertures 32 throughout its extent. The floor also includes a plurality of circular apertures 38 throughout its extent in vertical alignment with the apertures 32 in the roof. The floor 24 also has a centrally located rectangular aperture 40 measuring about one third of the width of the slide bar 12 and extends from one short side to the opposite short side. The remainder of the floor 24 consists of two noncontiguous segments 42, 44 abutting the vertical side walls 26 of the slide bar and measuring about one third of the width of the slide bar 12. The noncontiguous segments 42, 44 of the floor include short vertical walls 46, 48 at the ends opposite from the vertical side walls thereby defining the central aperture 40 of the floor. The ceiling slide bar is adapted to be affixed to a sturdy upper support surface such as a ceiling beam.
A roller assembly 14 consists of two cylindrically shaped axles 54, 56. Each axle 54, 56 has a wheel 58, 60 attached to its opposite ends for rotational mobility of the roller assembly 14. The roller assembly 14 also has a generally tubular main body piece 62. The main body piece 62 is positioned at right angles to the axles 54, 56 with the axles extending through the main body piece 62 proximate to its ends. The main body piece 62 also includes a centrally located planar circular member 64 with a vertical aperture therethrough 66. The aperture 66 also includes a plurality of internal screw threads 68 throughout its extent. The roller assembly is adapted to roll in the slide bar from one side to the other. The four wheel construction of the roller assembly allows the child to move with a minimum of effort.
A spring 16 has an upper extent 76 formed as a straight cylindrical member with a plurality of external screw threads. The spring 16 has a lower extent 80 formed as a curved hook. The spring 16 has a plurality of circular coils 82 between its upper extent 76 and lower extent 80. The spring is adapted to be suspended from the circular member without interfering with the mobility of the roller.
A child seat 18 has a generally rectangular shaped back section 90 with a curved lower portion 92. The back section 90 has a planar, generally rectangular shaped member 98 with an aperture therethrough extending perpendicularly from the approximate center point of the back surface of the back section 90. The child seat 18 also has planar, generally rectangular front section 100 and side sections 102, 104 with rounded edges which measure about one half the vertical height of the back section 90. The front section 100 includes two large circular holes 108 at it lower extent to allow extension of a child's legs therethrough. The side sections 102, 104 include small slots 110, 111 at their upper extent. The child seat 18 also includes a planar, generally rectangular bottom section 112 and an open top section 114 for placement of a child. The seat is adapted to comfortably support children of varying ages.
A support harness 20 has an upper end with a single strap 120 terminating in a long fold over loop 122. A ring 124 is coupled to the long fold over loop 122 and removably received by the hook 80 at the lower extent of the spring. The harness 20 also has a lower end consisting of three straps 126, 128, 130 terminating in short fold over loops, 127, 129, 131. One of the short loops 129 is connected to the aperture in the perpendicularly extending member 98 on the back section of the child seat. Two of the short loops 127, 131 are connected to the slots 110, 111 in the sides of the child seat. The three straps 126, 128, 130 are joined to the single strap 120 of the upper end with a coupling mechanism 124 located a short distance below the long fold over loop 122. The lengths of the straps may be adjusted by manipulating the coupling mechanism joining the straps. The straps are comprised of sturdy materials to insure safe support of the child.
The suspendable child walker system is essentially a moveable jumper seat for infants and young children. The spring component allows a child to jump up and down while in the seat. The roller assembly in the ceiling slide bar permits a child to move five to six feet forward and back without risking injury from bumping into door jams or other potentially harmful obstacles. The apparatus therefore allows more mobility for the child by moving the child away from the doorway and into the living room. The apparatus also enhances the safety of the child by moving them out of door ways and other such areas inconvenient to adults.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
