Force Transfer Harness and Method

Abstract

A force transfer harness that utilizes the harness structure to redirect the handler's forces through the harness structure and into the underlying ground is provided. Through the act of the dog sitting, the associated dog and handler cause a change in the orientation of the harness legs that allows the harness to form a support structure. After the dog sits, the harness legs are brought in contact with the ground, whereas previously they were hovering above the ground in a ready orientation. As a result, the dog's act of sitting enables the human to transfer his or her weight through the harness and into the ground.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to and is a continuation of U.S. application Ser. No. 13 / 787,162 filed on Mar. 6, 2013, now pending, which is hereby incorporated into this specification by reference in its entirety.BACKGROUND OF THE INVENTION[0002]A specially trained mobility assistance dog with associated mobility harness, often referred to as a walker dog, is used to assist individuals that have some form of impairment that makes it difficult for them to walk unassisted. The aforementioned impairment is often the result of a birth defect, physical injury, mental injury, or underlying disease such as Parkinson's disease or arthritis. The walker dog is often fitted with a mobility harness that transfers the forces exerted by the human handler into the dog's front shoulders and front legs. By using the dog fitted with the mobility harness as a “portable walker”, the handler gains assistance with balancing, gait, and their ability to ambul...

AI Technical Summary

Benefits of technology

[0009]The present invention provides a force transfer harness (“FTH”) that utilizes the harness structure to redirect the handler's forces, through the harness structure, and into the underlying ground. This alleviates the need to use a large breed dog for motion assistance when using the invention since all of the handler's forces are directed through the harness structure into the ground rather than through the dog's shoulders and front quarters. At the same time, the invention is easily adaptable to a medium size dog without the need for extensive mobility training that is associated with current mobility assistance dogs and harnesses. The FTH provides the stability through its structure rather than via the dog's girth. Additionally, the FTH provides on demand support should the handler suddenly lose balance and need to use the invention as an instantaneous means for support. Since the invention transfers the handler forces through its own structure and into the underlying ground, the need for the dog to maintain 100% alignment with the handler is eliminated. Therefore, the training required to coordinate the dog's motion and gate with that of the handler is also greatly reduced.

[0010]The FTH takes advantage of a dog's ability to sit on a given command. Through movement of the FTH handle, a verbal command, or the dog's training associated with harness load sensing, the dog responds by going into a sitting posture when the handler needs support. As the dog sits, the invention forms a support to allow the disabled person to fully transfer their weight through the FTH structure to the underlying ground without redirecting any forces through the dog. The result is a mobility assistance device that can utilize a medium sized dog having little additional mobility assistance training that still provides full on demand support for a disabled handler.

Problems solved by technology

However, large breed dogs often don't fit well into many living environments.

This group tends to have increased difficulties in caring for and living with larger breed dogs.

Additionally, training the dog to alert the handler to impending dangers such as oncoming traffic can be at odds with the dog's primary function of mobility assistance.

At the same time, the associated costs and time involved in training a walker dog limits their penetration within the disabled community.

However, all of these patents still require that all of the handler's forces are directed through the harnesses into the dog's shoulders and front quarters.
