Patent number: 12102587Abstract: An improved crutch includes an improved shock absorbing mechanism, lighting components, and an improved tip component. The improved shock absorber mechanism utilizes compressible spheres that are compressed when a person supports all or partial of their body weight onto the crutch and are uncompressed when the weigh is removed. This compression of the spheres absorbs any impact from the walking surface to the person's body. The elasticity of the compressible spheres is adjusted by forming a central through-opening through the sphere, varying the number of the sphere, their diameter and material.Type: GrantFiled: July 23, 2022Date of Patent: October 1, 2024Inventors: Craig Battuello, Alexander Mitchell

Patent number: 7992584Abstract: A walker with wheels that are retracted upon the application of a force of predetermined magnitude to permit a user to move the walker when he or she partially leans on the walker while providing a solid anchored support if he or she leans with more weight exceeding a predetermined magnitude. The walker includes a structural elongated assembly with a handle and forearm cuff at one end. The other end is rigidly mounted to two base assemblies that are kept at a parallel and spaced apart relationship with respect to each other. The base assemblies have a bottom surface. Retractable wheels are mounted to the base assemblies. The wheels are spring biased to protrude beyond the bottom surface so that they support the walker when at rest and as long as the user does not apply a force that exceeds a predetermined magnitude.Type: GrantFiled: April 20, 2010Date of Patent: August 9, 2011Inventor: Bernardo Birnbaum

Patent number: 7954502Abstract: An improved mobility assistance apparatus for use by a person as a walking aid, e.g. a cane, crutch, or walker, has a support capable of bearing vertical forces during use of the apparatus as a walking aid and a resilient device connected to a lower portion of the support for ground engagement. The device has a dynamic response characteristic to forces associated with ambulating using the apparatus as a walking aid which generates propulsive force to aid mobility. Two coiled springs are monolithically formed with the device at an upper end thereof. A flexible elongated member is connected to a radially inner, free end of each of the coiled springs and extends about a return at a lower portion of the device for resiliently expanding the coiled springs to store energy with force loading of the apparatus during use and to release stored energy during force unloading to generate propulsive force to aid mobility.Type: GrantFiled: December 22, 2006Date of Patent: June 7, 2011Assignee: Bioquest Prosthetics, LLCInventors: Barry W. Townsend, Byron K. Claudino

Publication number: 20110073146Abstract: A removable shock absorbing tip for a walking aid. The tip may be comprised of a shaft engaging member for connecting the tip to the shaft of a walking aid, an outer shell, and a biasing member. The biasing member may disposed within the outer shell in abutment with the shaft engaging member. The biasing member may also be disposed around the shaft engaging member and in abutment with the outer shell. The biasing member may be a spring, a fluid-filled cushion, or a member formed of elastomeric material. The outer shell may be formed of transparent or translucent material to permit the biasing member to be visible to a user for ease of identification.Type: ApplicationFiled: September 28, 2009Publication date: March 31, 2011Applicant: Stander Inc.Inventor: F.

Publication number: 20110073145Abstract: The present invention includes a walking cane having a handle assembly, a support assembly and foot member. The handle assembly includes first and second generally upright rigid posts. A shaft adaptable for grasping by a user's hand connects to each end of the posts. Pliable mounts dispose between the terminal ends of the shaft and each post. The mounts, biased against the shaft, permit omni-directional movement of the shaft relative to each post. The support assembly connects to the handle assembly and includes three parallel elongated rods spaced apart from one another in a triangular formation. The handle assembly can be adjusted relative to the support assembly by means of two cooperating shims. The foot member connects to the support assembly and contacts the ground. The cane provides a light-weight shaft and a shock absorbing handle assembly to assist in relieving hand, wrist and arm strains.Type: ApplicationFiled: September 29, 2010Publication date: March 31, 2011Applicant: KINETICANE, LLCInventors: RONALD M.
