Description
Background of the Invention
This invention relates generally to infant or toddler walkers and more specifically to toddler walking training devices which are supported by one or more parents or adults.
Adult supported infant walking aides are known in the art. An early example is U.S. Pat. No. 1,193,374, entitled "Baby Walker" and issued on Aug. 1, 1916 to Gilliam. This device utilized a harness with adjustable waist belts and an adjustable handle. This device, however, has no crotch support, no adjustable shoulder straps, no safety tether, and can only be operated by a single adult.
Another example is U.S. Pat. No. 1,749,999, entitled "Manually-Held Supporting Device For Assisting Children In Learning To Walk" issued on Mar. 11, 1930 to Crocker. This device provides a vest like harness along with two support straps. It has no crotch support, no shoulder strap adjustment, no support strap adjustments, and uses an inefficient lace type fastener. Further, the support straps are not releasable and there is no safety tether.
A more recent example of adult supported infant walking aides is shown by U.S. Pat. No. 5,120,287, entitled "Infant Walking Aide" and issued on Jun. 9, 1992 to Brown et al. This device shows a harness with crotch support and a bar by which an adult can support the device. However, this device presumably offers no adjustability. The harness loosely encloses the toddler. It has only a single belt strap encircling the toddler's waist and no shoulder straps. The lack of support straps makes the toddler susceptible to flipping backward or forward. The small bar handle allows the device to be operated by one hand of an adult, but it precludes other desirable configurations, such as two adults supporting the toddler simultaneously.
Clearly, there exists a need for an improved adult supported child walking aide which: 1) is fully adjustable, 2) is adaptable to many different support configurations, 3) can be supported by one or two adults (thus sharing the load), 4) prevents a toddler from flipping backwards, 5) has a harness which may be worn by a toddler when the support straps are detached, and 6) provides a safety tether for added security in dangerous areas.
Summary of Invention
The invention creates an infant walking aide device which helps an adult to assist a small child or toddler in learning to walk. A fully adjustable harness is supported by a crossbar which is held by the adult. The harness has straps which fit over the child's shoulders, under the child's crotch, around the child's waist, and across the child's upper back.
The crossbar and suspending straps clip to the harness for easy attachment and release. The suspending straps are adjustable in length to accommodate various carrying configurations. The crossbar is width adjustable and may be grasped by either one or two adults. In addition, the crossbar is curved so that it can be placed over an adult's head and supported by the adult's neck and shoulders. Finally, a safety strap or tether attaches between the harness and the adult for use as either a leash or a safety tether providing added security.
The fully adjustable harness includes two adjustable waist or body belts and two adjustable shoulder straps. Being fully adjustable, the harness fits snugly around the toddler's torso and precludes the toddler from falling or slipping out of the harness. Because of the snug fit, the harness may be worn by the toddler when the suspending straps and safety tether are removed. The harness is easily secured around the toddler or removed from the toddler by quick release fasteners on the waist belts.
The crossbar and suspending straps are likewise fully adjustable. The suspending straps are length adjustable to accommodate various size adults and to permit the crossbar to be placed over the adult's head and supported by the neck and shoulders. To accommodate placing the crossbar over the neck, the crossbar is curved and fully padded. Finally, the crossbar is width adjustable making it adaptable to various supporting configurations, including being supported by one hand, two hands, or by two adults.
A final attribute of the invention is the safety tether. The safety tether attaches between the harness and the adult and serves as both a child leash and as a safety line. When the crossbar and suspending straps are removed, the safety tether serves as a leash restraining the child from moving too far from the adult. When the crossbar is used, the safety tether is secured to the adult's wrist or waist. If the adult should happen to, for instance, stumble and drop the crossbar when near a cliff, hill, or other precarious location, the safety tether prevents the child from falling too far over the precipice.
Numerous embodiments of this invention are envisioned and some are described below.

Detailed Description of the Drawings
FIG. 1 shows the preferred embodiment of the invention.
Toddler walking aide 10 is comprised of crossbar 11, suspending straps 12, harness 13, and safety tether 14. Harness 13 is further comprised of shoulder straps 13A, back support strap 13B, upper waist or body belt 13C, lower waist or body belt 13D, crotch straps 13E, and clips 13F.
Crossbar 11 is preferably made of lightweight tubing covered with thick foam padding. Handles 11A are formed by the crossbar extending beyond the suspending straps 12. In one embodiment, crossbar 11 is width adjustable via a conventional push button locking arrangement 11B.
Suspending straps 12 are length adjustable via fasteners 12A commonly known in the art. One end of suspending straps 12 attach to crossbar 11. A second end of suspending straps 12 easily clip to harness 13 via rings 12B and clips 13F.
Harness 13 is meant to fit snugly around a toddler and is therefore fully adjustable. Shoulder straps 13A are adjusted via shoulder strap adjustment means 13G. Similarly, waist belts 13C and 13D are adjustable via quick release buckles 13H which include strap adjustment means. Being fully adjustable permits the harness 13 to be custom fit to the toddler resulting in a high degree of security in holding the toddler. This design also allows the harness 13 to remain on the toddler when the suspending straps 12 and safety tether 14 are removed thus eliminating the cumbersome task of removing and reattaching the harness 13 each time the walking aide device 10 is to be used.
A disadvantage in the prior art is the tenency of a toddler to flip rearward. This flaw is eliminated in the current invention by the back support strap 13B. The back support strap 13B attaches between the shoulder straps 13A and is positioned high on the toddler's back. This position provides the added support to prevent a rearward flip and any associated injury. In the preferred embodiment, the back support strap 13B is also the attachment point for the safety tether 14.
The harness is constructed using materials, fasteners, and manufacturing techniques commonly known in the art. The preferred embodiment uses nylon material fastened together with rivets. It is readily recognized that many similar materials and fasteners may be substituted.
FIG. 2 shows the invention supporting a toddler and the crossbar being held by one or two hands of the operator(s).
Crossbar 11 is grasped by either one hand in the center of the crossbar 11 or by two hands at each end of the crossbar 11. Handle portions 11A make it convenient for two adults to assist the toddler simultaneously. Suspending straps 12 attach to clips 13F and support harness 13.
FIG. 3 shows the invention, the safety tether, and an adult operating the device.
The adult grasps the crossbar 11 providing support to the harness 13 and toddler. The safety tether 14 clips or attaches to the rear of the harness 13. The opposite end of the safety tether 14 attaches to the wrist of the adult or alternatively, to the waist of the adult. The preferred embodiment uses hook and loop fasteners (i.e. VELCRO.TM.) for this purpose.
FIG. 4 shows a curved crossbar adapted for use behind the neck of the adult or operator. This is useful when, for various reasons, the operator does not want to support the toddler with his/her hands. For example, when the operator is carrying something in his/her arms, doing something with his/her hands, or merely desires a different configuration.
FIG. 5 shows a width adjustable crossbar with a button locking mechanism. The width adjustment is particularly useful in shortening the crossbar 11 for a single operator, or lengthening the crossbar 11 for use by two operators.
FIG. 6 shows the device used with the crossbar supported by the neck and shoulders of the operator.
This configuration frees the hands of the operator while still supporting the toddler. The curved crossbar 11 rests on the operator's neck and shoulders. The suspending straps 12 are fully extended and attach to the harness 13 which supports the toddler.
The major portions of the harness 13, suspending straps 12, and safety tether 14 are preferably made of strong nylon material, however, those skilled in the art recognize that numerous other materials may be utilized. Likewise, all clips and buckles used in the toddler walking aide are preferably of the plastic or nylon quick fasten and release type commonly known in the art.
This general description of the preferred embodiment has been for descriptive purposes only and is not intended to limit the scope of the invention. Those of ordinary skill in the art readily recognize alternate embodiments including, but not limited to, using alternate materials, fasteners, buckles, and similar devices known in the art which perform substantially the same function in substantially the way.
It is clear from the foregoing that the present invention represents a new and useful device for use by an adult in assisting a toddler to walk.
