Abstract
An apparatus for establishing dynamic ground contact is disclosed. A ground contact tip is attached to one end of an elongate member. The ground contact tip contains a connecting portion and a base portion that is opposite the connecting portion. A flexible core connects between the base portion and the connecting portion. At least one limiting ring is positioned on the flexible core. The elongate member is permitted to rotate through a range of angles while the flexible core allows the base portion to remain flat against the ground. At the maximum allowable angle, the limiting rings allow the ground contact tip to cease flexing and become rigid, so that the user can push against the ground at an angle, while the base portion remains flat against the ground.
Claims19
An apparatus for establishing ground contact with an elongate member, the apparatus comprising:
- a connecting portion;
- a base portion positioned opposite the connecting portion;
- a flexible core connecting the base portion with the connecting portion;
- and
- a first and second limiting ring positioned on the flexible core, each ring having a diameter and a thickness and
- where the distance between the connecting portion and the first ring, the distance between the first ring and second ring, the distance between the second ring and the base, and the thicknesses of the first and second rings are substantially equal to one another.
An apparatus for establishing ground contact, the apparatus comprising:
- an elongate member having a first end and a second end;
- a grip attached to the first end of the elongate member;
- a ground contact tip attached to the second end of the elongate member, the ground contact tip comprising:
- a connecting portion which is adapted to attach with the elongate member;
- a base portion positioned opposite the connecting portion;
- a flexible core connecting the base portion with the connecting portion;
- and
- at least one limiting ring positioned on the flexible core, each ring having a thickness and
- where the distance between an uppermost ring and the connecting portion, the distance between adjacent rings, the distance between a lowermost ring and the base, and the thicknesses of the rings are substantially equal to one another.
An apparatus for establishing ground contact with an elongate member, the apparatus comprising:
- a connecting portion which attaches with the elongate member;
- a base portion positioned opposite the connecting portion and having a diameter;
- a transition shoulder attached to the connecting portion, said shoulder increases in diameter continually from the connecting portion towards the base portion and has a lower diameter;
- a flexible core connecting the base portion with the transition shoulder;
- a first limiting ring positioned on the flexible core and having a diameter that is larger than the lower diameter of the transition shoulder;
- and
- a second limiting ring positioned on the flexible core and having a diameter that is larger than the first limiting ring.
