Abstract
Putting is a very important factor in golf playing. Above all, a putting distance feeling is the hardest to master, and many rounds in golf courses are said to be required for improving putting. Nevertheless, a putter mat is normally only 2- to 3-m long, and a carpet surface or the like that offers the same rolling as by golf greens is hardly available. Many smooth floor surfaces found in homes and firms cannot be used for putting practice due to excessive rolling of golf balls. It is an object of the present invention to eliminate these drawbacks. A ball implement for practicing golf putting is invented which includes a disc provided at the center thereof with a hole, and a main body having a cylindrical portion.
Claims16
A ball implement for practicing golf putting, comprising:
- a bottom portion comprising a disc having a hole at its center,
- a trunk portion formed by erecting a cylindrical portion or semi-spherical portion, concentrically with the hole, on said bottom portion to accommodate a golf ball or a mimic golf ball for rolling therein, thus enabling practicing putting on a smooth floor surface;
- and
- an annular magnetic body disposed on a bottom surface,
- wherein said ball implement is employed together with a cup for practicing golf putting in which a thin, strong magnet is buried at a center of a disc having a slanted periphery such that a peripheral portion of said disc comes into tight contract with a floor surface when the cup is placed.
A ball implement for practicing golf putting, comprising:
- a disc portion in the form of a plate provided at a center thereof with a hole, said disc portion including:
- an upper side;
- and
- a bottom side forming a bottom surface of said ball implement and defining an outer diameter;
- and
- an accommodating portion extending from said upper side of said disc portion and surrounding said hole, said accommodating portion including an open top having an inner diameter larger than a diameter of a golf ball, said accommodating portion adapted to be struck by a putter head and adapted to accommodate the golf ball such that the golf ball can roll therein when said accommodating portion is struck by the putter head,
- wherein a maximum outer diameter of said accommodating portion is smaller than an outer diameter of said bottom side of said disc portion.
An implement for practicing golf putting, having a ball implement and a cup, wherein said ball implement comprises:
- a disc portion provided at a center thereof with a hole;
- an accommodating portion erecting on said disc portion to surround the hole and accommodating a golf ball such that the golf ball can roll therein;
- and an annular magnetic metal plate arranged on said disc portion to surround the hole, and said cup comprises:
- a disc slanted downward from a central portion thereof to a peripheral portion thereof;
- and a magnet buried at the central portion of said disc.
An implement for stably supporting a golf ball while practicing putting on a smooth floor surface, the implement comprising:
- (A) a bottom portion in the form of a thin annular ring, the bottom portion including:
- (i) a circular outer periphery having a first diameter;
- (ii) a circular inner periphery, the inner periphery having a second diameter that is less than the first diameter;
- (iii) a smooth flat bottom surface configured to slide across a smooth floor surface, the bottom surface extending from the outer periphery to the inner periphery;
- and
- (iv) a top surface extending from the outer periphery to the inner periphery;
- and
- (B) an accommodating portion in the shape of a partial semi-spherical cup, the accommodating portion including:
- (i) a circular top end having a third diameter, the third diameter being less than the first diameter and larger than a diameter of the golf ball;
- (ii) a circular bottom end defining an aperture, the aperture sized to allow a bottom portion of the golf ball to extend through the aperture to contact the smooth floor surface, the aperture being smaller than the diameter of the golf ball wherein the golf ball is prevented from passing entirely therethrough;
- and
- (iii) a thin body coupled to the bottom portion, the thin body including an interior surface and an exterior surface, the thin body extending between the bottom end and the top end, wherein the interior surface has a partial semi-spherical shape, wherein the exterior surface is shaped to follow a shape of the golf ball and is arranged and configured to be struck by a putter, and wherein the interior surface is arranged and configured to provide frictional resistance when the golf ball is rolling within the accommodating portion to simulate rolling of the golf ball on a putting green.
