Abstract
A balancing aid for a human that is generally U-shaped, having a center portion for a first human to hold on to such that they can provide stability to a second human holding onto a pair of arms extending downward from the center portion.
Description
- This application claims priority to U.S. provisional patent application Ser. No. 62/073,416, for “A WALKING AIDE FOR BABIES AND TODDLERS” filed on Oct. 31, 2014 which is hereby incorporated by reference in entirety for all purposes.
- The described embodiments relate generally to a balancing aid for a human. In one embodiment the balancing aid is configured to be held by an adult such that a toddler can grasp a pair of arms of the walking aid and be stabilized while learning to walk.
- Currently there are a wide variety of walking aids for toddlers that use wheels and help support the toddler's weight while they learn to walk. However, such devices do little to help the toddler to develop the necessary coordination required to walk and they typically do not work well on a variety of surfaces.
- New walking aids for toddlers may require new features or new designs to help the toddler develop the necessary coordination to walk while supporting at least a portion of the toddler's weight.
- In some embodiments a balancing aid for a human comprises a generally U-shaped structure comprising a center portion having a first grip region positioned in an approximate center of the center portion and a first arm rigidly attached to and extending from a first side of the center portion to a first distal end and oriented at an angle between 30 to 120 degrees from a longitudinal centerline of the center portion. A second arm is rigidly attached to and extends from a second side of the center portion to a second distal end and is oriented at an angle between 30 to 120 degrees from the longitudinal centerline of the center portion. A second grip region having a cross-sectional area between 0.05 and 2.0 square inches is located on the first arm proximate the first distal end, and a third grip region having a cross-sectional area between 0.05 and 2.0 square inches is located on the second arm proximate the second distal end. The second grip region and the third grip region are separated by a distance between 5 to 15 inches; and the first grip region is separated from the second and the third grip regions by a distance between 5 to 24 inches.
- In some embodiments the center portion and the first and the second rods are made from a material having a modulus of elasticity of greater than 100,000 pounds per square inch. In various embodiments the first grip region has a larger cross-sectional area than the second or the third grip region. In some embodiments the second grip region and the third grip regions each have a grip retention feature configured to improve the ability of a human to maintain a grip on the second and the third grip regions. In various embodiments the grip retention feature comprises an enlarged cross-section at the first and the second distal ends.
