ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The instant invention relates generally to pocket knives and repair tools and more specifically it relates to an impact relief tool. The impact relief tool is constructed for use by a greens keeper, to relieve an impact caused by a golf ball striking and indenting the surface of a golf green.
2. Description of the Prior Art
Numerous pocket knives and repair tools have been provided in prior art. For example, U.S. Pat. No. 2,647,311 to Arden; U.S. Pat. No. 2,914,850 to Kuhnl; U.S. Pat. No. 3,049,182 to Pelow; U.S. Pat. No. 5,405,133 to Upton; U.S. Pat. No. 5,449,169 to Hardin et al. and U.S. Pat. No. 5,562,553 to Digerness et al. all are illustrative of such prior art. While these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described.

DETACHABLE BLADE POCKET KNIFE
U.S. Pat. No. 2,647,311
A pocket knife comprising a handle, a shank pivoted at one end to the handle for swinging movements between open and closed positions relative thereto. The shank at one face thereof and near its pivoted end being recessed and thereby being provided with an inwardly facing shoulder at the outer end of the recess. The shank outwardly of the recess being of substantially uniform thickness from face to face and the upper and lower edges of the shank outwardly of the shoulder being substantially parallel. The edges having therein channels which extend longitudinally of the shank and which are aligned with the face of the recess. The channels open through the outer end of the shank and have their inner ends terminating outwardly of the shoulder. A thin, laterally flexible, normally flat blade has therein a longitudinally extending slot the outer end portion of which is of a width approximately equal to the distance between the bottoms of the channels in the shank. The blade-slot being otherwise of approximately the same size and shape as the shank outwardly of the shoulder. It is engageable and interlockable with the shank by sliding the same rearwardly relative to the shank under lateral flexure to engage portions thereof at both sides of the slot therein with the grooves of the shank and to engage the portion thereof at the rear end of the slot therein behind the shoulder.

RAZOR BLADE KNIFE
U.S. Pat. No. 2,914,850
A razor blade pocket knife comprising, a handle having a vertical slot formed therein. A blade holder is pivotably mounted at one end of the handle for movement between an open position and a closed position within the slot. The holder has a U-shaped cross section inverted when in the closed position. A blade carrier is pivotably mounted at the one end of the handle coaxial with the holder and pivotable relative to the holder and in the plane thereof to a position within the holder. Means on the carrier is adapted to support a razor blade whereupon the carrier and the blade are adapted to be pivoted into the holder with the cutting edge of the blade projecting therefrom. Means defining a notch formed in the handle extends transversely through the slot and extends in depth beyond the inverted edges of the U-shaped blade holder when in the closed position in the slot. The edges where the blade projects from the holder act as abutments engageable by a person's fingernails to facilitate opening of the knife.

TURF REPAIR TOOL
U.S. Pat. No. 3,049,182
A hand manipulated turf working tool comprising handle means including a substantially planar member. A blade abutment element is positioned at one end thereof. The blade abutment element has a first surface. A blade assembly includes a blade support portion pivotally connected to the end of the planar member, remote from the end accommodating the abutment element. A plurality of spaced turf-penetrating tines are connected at one end to and project longitudinally of the blade support portion. The turf-penetrating tines each having a curvilinear cross-section. The turf-penetrating tines are arranged coplanar and are arranged relative to one another, so that the spaced between adjacent tines exceeds the width of the tine. The first surface has a height above the planar member at least as great as that of the blade support portion. The blade assembly from the pivotal connection to the free ends of the tines are of such length that the blade assembly has a first operating position wherein the blade assembly forms an axial extension of the handle means and a second storage position wherein the blade assembly overlies the planar member with one of the turf-penetrating tines engaging the first surface and the ends of the tines disposed below the upper vertical limit of the first surface.

FOLDING BALL MARK REPAIR TOOL
U.S. Pat. No. 5,405,133
Disclosed is a folding ball mark repair tool for repairing a ball mark depression in a golf green resulting from impact of a golf ball landing on the green, thereby leaving the green free of a surface irregularity that may adversely effect putting conditions. The ball mark repair tool comprises an elongated flat blade for insertion under a concave ball mark in greens turf for prying the turf upwardly for smoothing thereof. The blade has two parallel pointed prongs extending from an end thereof. An elongated flattened handle has a longitudinally central slot formed therein, wherein the blade shank is pivotally disposed such that the blade may be pivoted to a storage position thereof, wherein the blade is disposed within the slot and a working position thereof, wherein the blade is approximately 180 degrees from the storage position extending out of the slot. A spring pivotally biases the blade to the working position. A latch is included whereby the blade may be releasably retained in the storage position. The latch is biased to a blade engageable latch position and also has a blade disengageable release position. The latch also has a finger engagement button formed on one end thereof which projects slightly above the surface of the handle when the rod is in the latch position, whereupon finger pressure by a user causes the blade to spring from the storage position to the working position.

RETRACTABLE DIVOT REPAIR TOOL
U.S. Pat. No. 5,449,169
A retractable divot repair tool assembly comprising a divot repair tool in a generally planar configuration. The tool has long parallel side edges, a short linear bottom edge coupling the side edges and an upper portion formed in a generally V-shaped configuration. The lower portion of the tool being in a generally rectangular configuration of a length slightly less than the length of the upper V-shaped portion with an aperture therethrough and a recess in the aperture. A housing in a generally box-like configuration has rectangular front and rear walls, a bottom wall at right angles with respect thereto and parallel side walls coupling the side edges of the front and rear walls and the side edges of the bottom wall, the container having an opened upper end. The container also having a longitudinal slot on the front wall along the majority of its length thereof parallel with the side walls and with short upper and lower transverse slots adjacent to the upper end and lower end of the longitudinal slot. Mechanisms are to move the divot repair tool between a stored orientation within the container and an operative orientation exterior of the container.
