Abstract
A retractable golfer's divot tool comprising a housing, a divot tool slidable inside the housing, a spring connected between the housing and the divot tool and a locking mechanism to lock the divot tool in certain positions. The spring biases the divot tool to extend from the housing so that when the golfer presses a button member in the locking mechanism, the divot tool automatically extends from the housing. Once extended, the locking mechanism locks the divot tool in place allowing the golfer to repair the ball marks on the green. To retract the divot tool back into the housing, the golfer again presses the button member and manipulates a sliding lever to draw the divot tool back into the housing where the locking mechanism again locks the divot tool in place.
Description




The present invention relates to a retractable divot tool for golfers used to manually repair ball marks on greens.




BACKGROUND OF THE INVENTION




Varying designs of divot repair tools are well known in the art. These tools are used to repair the divot remaining on a golfing green following the impact of a golf ball. To prevent damage to the green and to keep a smooth surface, the golfer must repair such mark by lifting the impacted area to fill the cavity. The general design of the golf tool has a pair of tines which are stuck into ground surrounding the divot and manipulated to bring the surrounding turf into the cavity.




However, with the use of such tools, the tines become dirty or muddy after sticking them into the ground. If a golfer carries such devices in his pocket, his pockets will become dirty. These devices are also of such a design that the tines could poke the golfer either when in the pocket or when the golfer reaches into his pocket.




Other designs have divot repair tools retractable into a cover assembly. Such design is disclosed in U.S. Pat. No. 5,449,169 (Hardin et al.) comprising a divot repair tool and a housing with a slot and transverse slots at the ends of the larger slot. The mechanisms for extending and retracting the tool are used in conjunction with the transverse slots whereby a locking mechanism is biased to enter the slot to lock the tool in place. However, the user must push in a button and manually move the tool from the retracted to the extended position or vice versa.




Other devices use a slidable divot tool in conjunction with other tools. U.S. Pat. No. 5,562,553 (Digerness et al.) discloses a slidable divot tool in conjunction with a pencil sharpener. U.S. Pat. No. 5,388,824 (Reimers) discloses a retractable divot tool in conjunction with a plurality of other devices, such as a ball marker, iron groove brush and a picking tool. Such tools provide a compact divot tool device. However, such tools also require a manual sliding of the divot tool to the extended position.




SUMMARY OF INVENTION




It is therefore an object of the invention to provide a retractable divot tool having a spring assisted tool extension. It is another object of the invention to provide a divot tool capable of retracting into a housing to prevent the user's pockets from accumulating dirt and mud during a round of golf It is a further object of the invention to provide a retractable divot tool to prevent the user from being poked by the tool when the tool is not in use.




These and other objects are achieved with the use of the claimed invention. The invention comprises a housing, a retractable divot tool retractable into an out of the housing, a spring mechanism for assisting the extension of the tool from the housing and a button member for unlocking the tool when the tool is in its extended and retracted position. Upon manipulation of the button member, the divot tool via the spring mechanism is biased towards the extended position and is locked again when the tool is fully extended. Again upon manipulation of the button member and the manipulation of a lever member connected to the tool, the tool may be retracted back into the housing.

The inner structure of the divot repair tool is shown in detail in

FIGS. 4-9

. Repair member


410


is an elongated planar structure having a pair of tines


310


and


312


at an end thereof. Lever


120


is located on an adjacent side from the tines. Repair member


410


also has a slot


470


with two widths, a first width at a first end portion


440


and second end portion


441


at the ends of slot


470


and a second width along the middle portion


450


. Second width


450


is narrower than the first width at end portions


440


and


441


. The end portions


440


and


441


and second width


450


interact with button member


110


for locking and allowing movement of repair member


410


. Repair member


410


also includes pins


422


and


424


which interact with travel slot


420


of housing


100


to guide the repair member


410


along the length of housing


100


.




Divot repair tool


4


also includes a spring


400


located between housing


100


and repair member


410


. Spring


400


provides resistance to compression which biases repair member


410


to move away from the head portion of housing


100


and to extend tines


310


and


312


from housing


100


through holes


460


and


462


.




Button member


110


fits into slot


470


and includes two widths, a wide portion


520


and a narrow portion


510


. Wide portion


520


has a greater diameter than the second width


450


and a narrower diameter than the first width of end portions


440


and


441


. Narrow portion


510


has a diameter less than the second width


450


. Button member


110


can only move along its axis and is prevented from lateral movement by a through hole


130


in housing


100


(FIGS.


1


and


3


). A button spring


530


biases button member


110


in a direction opposite to direction P shown in

FIG. 5

, which aligns wide portion


520


with the second end portion


441


. Since wide portion


520


has a greater diameter than second width


450


, repair member


410


is locked into the retracted position as shown in

FIGS. 4 and 5

.




Upon a depression along the axis of button member


110


in direction P as shown in

FIG. 5

, narrow portion


510


becomes aligned with end portions


440


and


441


and second width


450


as is shown in FIG.


7


. Since narrow portion


510


is narrower than the first width of end portions


441


and


442


and second width


450


, repair member


410


is able to move relative to housing


100


and button member


110


in direction E. As repair member


410


is able to move, spring


400


pushes repair member


410


away from the head portion of housing


100


. This begins to extend tines


310


and


312


from housing


100


, as is shown in

FIGS. 6 and 7

.




Repair member


410


moves away from the head portion of housing


100


until button member


110


becomes aligned with the end of slot


470


at first end portion


440


. This corresponds to the full extension of tines


310


and


312


. At this point, the biasing of button member


110


by button spring


530


urges wide portion


520


into first end portion


440


which locks repair member


410


into its extended position as shown in

FIGS. 8 and 9

.




To return the tines


310


and


312


into their retracted position, button member


110


again must be pressed in direction P to align the narrow width


510


with end portions


440


and


441


and second width


450


which will again allow repair member


410


to move relative to housing


100


and button member


110


. The golfer then moves lever


120


of repair member


410


in a direction opposite E which begins to retract tines


310


and


312


into housing


100


. Once the golfer begins to retract repair member


410


, the golfer may then discontinue pressing button member


110


. When tines


310


and


312


of repair member


410


are fully retracted to the point where button member


110


aligns with second end portion


441


, button spring


530


will then move wide portion


520


of button member


110


into second end portion


441


which will lock repair member


410


in housing


100


as shown in

FIGS. 4 and 5

.
