BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention pertains generally to systems for standing, walking training and imaginative play for infants, new toddlers, and toddlers. More specifically, the invention relates generally to systems for young children's exercise and entertainment while also providing opportunities for standing and walking training for infants and new toddlers.

2. Description of the Prior Art

Frequently, children learn to walk by what has been called “furniture surfing” (e.g., infants who are just starting to stand, holding onto sofas, coffee tables, and other pieces of furniture for support as they navigate their way around a living room). At least in part, this may be due to the lack of an alternative method. Obviously, “furniture surfing” represents a risk to the infant, e.g., in the event the infant or new toddler should fall against a hard or sharp corner or edge of a piece of furniture or other item.

A primary alternative to “furniture surfing” can be referred to as “parent surfing,” that is, the active participation of the adult in holding the infant's hands while the infant attempts to stand or walk. This method is often short-lived due to adult fatigue.

Presently, there are few readily available alternatives which provide the functional combination of standing and walking training, exercise and entertainment for infants, new toddlers, and toddlers. Generally, the currently readily available alternatives fail to provide at least one of the desired functions and often have significant safety limitations, even with parental supervision.

Heretofore, other solutions have tended to be heavy, expensive, complicated, difficult to set up, difficult to manufacture, and costly to manufacture. In addition, safety-related features have been limited.

Therefore, a need exists for a system which is safe, inexpensive and easily manufactured, and provides infant walking training in combination with other functions.

In light of the above, it is an object of the present invention to provide a Child Activity System that is ideal for entertainment and development for young children. Further, it is an object of the present invention to provide a system for promoting infant exercise and entertainment. It is still further an object of the present invention to provide such a system that is adaptable to young children as they learn and grow older. It is yet still further an object of the present invention to provide a Child Activity System that is easily assembled, disassembled, transported and stowed. Still further, it is an object of the present invention to provide a Child Activity System that is lightweight and comparatively cost effective.

DETAILED DESCRIPTION OF DRAWINGS

Initially referring to FIG. 1, a Child Activity System 200 embodiment of the present invention is shown. System 200 can be characterized as a light-weight, strong, and stable structure made out of plastic pipes, e.g., ABS (Acrylonitrile Butadiene Styrene), or other child-safe plastic. System 200 further seeks to provide a safe and entertaining environment for an infant/new toddler/toddler 102 to learn and practice standing and walking skills in addition to aiding growth of the child by providing an entertaining and challenging environment for the continued play and development of toddlers and children.

Strength of system 200 is provided by advanced materials of plastic pipes and couplings that are extruded or molded from ABS or other child-safe plastic. As an example, pipe diameters could be in the range of ½″ to 1″ or more, if appropriate, and formed in a way comparable to Schedule 40 PVC. The diameter chosen will yield a bar circumference that is able to be grasped by the hand of a small child. System 200 stability is provided by its base that is comprised of two lateral support segments 125. The segments 125 form a base that is three (3) times as wide as the upper end bars 120. Further, segments 125 are more specifically comprised of two lower end bars 160 and a lower horizontal bar 112 connected via 90-degree elbow couplings 180.

The graspable area for infant/new toddler (child) 102 support and walking training is initially defined by an upper polygonal peripheral graspable bar 115, that, in a preferred embodiment, is rectangular in shape and is made up of two upper end bars 120 and two upper horizontal bars 110. The upper bars 110 are joined by several 3-way bar couplings 190, which may also be made from ABS or similar material. Graspable bar 115 provides child 102 with standing support, either by riding at the underarms or simply via child 102 grasping of the bar 115. The bar 115 also provides a sitting or crawling child with an upper bar to grasp while pulling himself/herself up to a standing position. As explained further herein, bar 115 is also important for the attachment of certain play and entertainment accessories.

FIGS. 2A and 2B additionally illustrate top and front views of this embodiment 200 of the present invention. Heights h1, h2, h3 of upper bars 110 and 120 are easily adjustable making system 200 ideal for small infants and new toddlers up through children who may learn to stand and walk at an older age. As shown in FIG. 2C, upper vertical support tube 140 is configured with a smaller diameter than that of lower support tube 150 and fits inside thereof telescopically. Vertical support tube 140 includes a spring button fastener 141 (FIG. 4C) wherein height h1, h2, h3 is easily adjustable by selecting corresponding hole 151 (FIG. 4B) for attachment.

In a preferred embodiment as shown in FIG. 3A, the invention 200 can be characterized as comprising two end support segments 300 along with two upper horizontal end bars 110 and two lower horizontal end bars 112.
