Shock Absorbing Patents (Class 135/82)
  • Patent number: 11832693
    Abstract: A shock-absorbing cane tip apparatus for user comfort and improved cane tip longevity includes a tip base having a base top side, a base bottom side, and a base perimeter. A tip sidewall is coupled to the tip base. The tip sidewall has a sidewall outer face, a sidewall inner face, and a sidewall top rim. The sidewall inner face defines a cane cavity to slidingly receive a tip end of a cane. A bottom plate is coupled to the tip base within the cane cavity. A compression spring is coupled to the bottom plate and is oriented perpendicular to the base top side. A top plate is coupled to the compression spring and engages a distal end of the tip end of the cane to compress the compression spring when weight is pushed onto the cane.

    Abstract: A walking stick that takes inspiration from nature to absorb energy in the downward first motion of a walking stride and then return the stored energy to aid in propelling the walker forward in the final forward motion of the walking stride all the while keeping the walker in an ergonomically correct position which minimizes discomfort and reduces wasted energy. The walking stick that is the subject of this patent application utilizes a dual flexure spring configured in an S-shape (hereafter referred to as an S-flexure spring) as an extension of the straight shaft of the stick. The shape and location of the S-flexure spring are such that the spring force helps propel the walker forward.

    Abstract: The invention provides a moulded crutch tip in addition to a method of manufacturing such a crutch tip. This method preferably uses a mould which defines a single continuous volume which in turn defines an upper region, and a lower region. A crutch tip is formed by closing off the upper or the lower region of the volume with at least one blank structure, and then introducing a first mouldable material into the remaining open region of the mould. This blank structure is then removed from the previously closed volume and then a second mouldable material is introduced into the mould. In some embodiments this manufacturing method may be fully automated.

    Abstract: A stick that is excellent in shock absorption and is also excellent in stability is provided. A stick body is provided with a telescopic extension pipe formed by fitting an outer tube and an inner tube together in a nesting manner. Inside the extension pipe, a velocity-dependent damper that damps the relative sliding movement between the outer tube and the inner tube, and a compression coil spring that concentrically fits onto the damper and urges the extension pipe so as to be extended are connected in parallel. According to such a stick, the shock transmitted to the hand can be mitigated as the compression coil spring contracts upon landing. Also, since the damper suppresses unwanted vibration of the extension pipe, the length of the stick quickly becomes stable after landing, allowing the user to keep stable balance with the stick.

    Abstract: A pseudo-frustoconical shaped unitary rubber end unit for an ambulatory device, such as a cane, comprising, a bottom hexagonal base and a top circular rim, wherein said base is about four times the diameter of said rim and functions to provide significantly enhanced support and stability; and a central cylindrical “socket” created by six deeply recessed side walls and a resultant six member rib-like frame that functions to optimize device's shock absorption capabilities and forward propulsion of the user. The hexagonal base may be asymmetrical or symmetrical, and the ribs may be of uniform or non-uniform dimensions. The hexagonal base and the rib-like frame act synergistically to compress and rebound under loads creating a twisting “spring assist” action that both absorbs shock and helps propel users forward. The broad base has a slightly recessed underside permitting the mobility device to be self-standing.

  • Publication number: 20110209733
    Abstract: The present invention relates to shock absorber insert for retro fitment into the body of an existing walking aid, such as a crutch, to dampen the impact force between the walking aid and a ground surface. Known shock absorbing walking aids can be relatively expensive to manufacture, heavy to use and do not provide for adjustment of the shock absorber. The shock absorber insert (1) of the present invention comprises a piston cylinder (11) with an end wall (11A); a piston (5) which moves axially within the piston cylinder (11) and a damper (10) located on a piston rod (9) and abut the end wall (11A) to reduce the speed of movement of the piston rod (9) within the piston cylinder (11). The shock absorber insert is either mid mounted between an upper (2) and lower (3) shaft or bottom mounted into a lower end of the lower (3) shaft.

  • Patent number: 7992584
    Abstract: 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.

  • Patent number: 7954502
    Abstract: 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.

  • Publication number: 20110073145
    Abstract: 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.

    Abstract: 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.

  • Publication number: 20100307549
    Abstract: Walking aids are described which are of simple construction but which allow for both resilience, i.e. the part of the walking aid which is gripped by the user and the ground-engaging end (3) can be resiliency pressed together, as well as a degree of angular flexibility so that the end (3) stays aligned with the ground even if the stick, crutch or the like (1) is angled relative thereto. This is achieved in particular by the use of a bellows structure (2) between the shaft (1) of a walking aid and a ground-engaging foot (3).
