The invention relates a divot repair tool that provides improved manipulation to twist the ground around a divot mark to close the hole inward toward the center of the divot and includes a prong portion with prongs configured vertically along a prong axis that is substantially orthogonal to the plane of the handle with the top prong longer which allows for an economically easier angle to promote the repair of bail marks that improves the playing conditions of the green.
Divot repair tools are used to repair divot marks on a golf green and usually include two prongs that extend from a handle. The prongs typically extend horizontally out from the handle wherein an axis between the prongs is parallel with or even in alignment with the plane of the handle. The prongs are inserted into the ground around a divot and then the handle is pressed downward toward the ground to lift the ground to lift the divot. This does not cover the divot with fresh grass but rather just lifts the divot and leaves a dirt spot on the green. Some people will resort to flipping existing tools to insert the prongs vertically and then move the entire divot tool inward toward the center of the divot in an attempt to push fresh ground and grass into the divot area. This is not ergonomic and difficult to close up the mark requiring increased hand pressure especially for some with arthritic hands.
An exemplary divot repair tool has a handle that extends along a plane and a prong portion having a first prong and second prong configured along a prong axis that is substantially orthogonal to the handle, or plane of the handle. This configuration enables easier manipulation of the divot repair tool to twist the ground around the divot inwards to close the divot hole with the thumb comfortably sitting at the twist point of the tool requiring less wrist and arm motions. The vertical prongs enable better repair of the divot. An exemplary divot repair tool is made of a monolith, made from a single piece of material, such as a molded material or sheet of planar material that is cut and further manipulated to create the divot repair tool as described herein. A piece of metal may be stamped to form the general planar shape of the divot repair tool and then this stamped piece may be twisted to configure the prong axis substantially orthogonal from the handle plane and thereby form the twisted portion between the prong portion and handle.
An exemplary divot repair tool has a handle and a prong portion including a pair of prongs with a twisted portion therebetween. The twisted portion is a twisted extension of the handle.
The length of the divot repair tool along the length axis from the handle end to the end of the tool may be about 50 mm or more, about 65 mm or more, about 75 mm or more, about 100 mm or less and any range between and including the length values provided. The overall length of the divot repair tool along the length axis may be 3.7 inches or about 94 mm. The handle has a length from the handle end to the tool end of the handle as measured along the length axis of the handle. This length may be about 40 mm or more, about 50 mm or more, about 65 mm or more, about 75 mm or less and any range between and including the length values provided. The length of the handle along the length axis may be 2.2 inches or about 56 mm. The handle has a width that extends from the first edge to the second edge along the width axis. The handle width may be about 10 mm or more, about 15 mm or more, about 20 mm or more, about 25 mm or more and any range between and including the width values provided. The length of the handle may be twice the width, or three times the width or even about four times the width of the handle and any range between and including the ratios provided. These ratios of length to width may be important for hand manipulation of the divot repair tool. The handle has a rounded handle end for comfort in the hand when using the divot repair tool. The handle has a thickness from a first surface to a second surface and this thickness may be uniform across the handle. The thickness may be about 1 mm or more, about 2 mm or more, about 2.5 mm or more, about 3 mm or more and any range between and including the thickness values provided. Again, the divot repair tool may be made out of a single piece or planar material that is stamped or otherwise cut and then twisted to form the divot repair tool.
The twisted portion is an extension from the handle that is twisted, wherein the first edge changes in orientation from the handle to the outer edge of the second prong and the second edge changes in orientation from the handle to the outer edge of the first prong. The first prong and second prong extend along a prong plane that is substantially orthogonal to the handle plane.
The first prong is longer than the second prong to reduce the force required for insertion into a ground surface. The length of the prongs is from the connected end, or most distal edge of the prong connector, to the extended end, and may be about 15 mm or more, about 20 mm or more, about 25 mm or more, about 30 mm or more, about 40 mm or more and any range between and including the length values provided. Also, the extended ends of the first prong and second prong have a prong axis that extends therethrough that is substantially orthogonal to the plane of the handle or width axis of the handle. The handle plane is defined by the planar surface of the first surface and second opposing surface that extend parallel wherein the handle is planar having a thickness from the first surface to the second surface. The divot repair tool has a twisted portion that couples the prong portion to the handle.
The prongs are also planar, each having a first surface and second surface that are parallel. The plane of the first prong and second prong are substantially orthogonal to the plane of the handle. The first prong has a length that is greater than the length of the second prong. There is a prong offset distance between the first prong extended end and the second prong extended end. This enables easier insertion into a ground surface as described herein. The extended ends of the prongs extend at an end-angle to aid in the insertion of the prong into the ground.
The first prong has a first edge along the outer portion of the prong and a second edge proximal to the second prong or along an inner edge of the first prong. The first prong has a thickness from a first surface to a second surface. The first prong has a length from a connected end to the extended end. The extended ends of the first and second prongs extend at an end-angle to produce a pointed surface or edge at the extended end for facilitating ground insertion. As described herein, the end-angle is an angle from orthogonal to the length axis or width axis of the handle. Note that the extended end-angles extend inward toward the handle and towards the opposing prong, wherein the extended end-angle of the first prong extends from the first edge back toward the handle end, and wherein the extended end-angle of the second prong extends from the first edge back toward the handle end.
The second prong has a first edge along the outer portion of the prong and a second edge proximal to the first prong or along an inner edge of the first prong. The second prong has a thickness from a first surface to a second surface. The second prong has a length from a connected end to the extended end. The extended end extends at an angle to produce a pointed surface at the extended end for facilitating ground insertion.
The first twisted portion extends from the handle to the first prong and the second twisted portion extends from the handle to the second prong. The two twisted portions twist from the width axis or the handle to the prong axis hat extends between the first prong and second prong. The prong axis may be substantially orthogonal to the width axis wherein the prong offset angle between the width axis of the handle and the prong axis along the first prong is between 75 degrees and 105 degrees
