in reference to fig1 - 4 , a golf putting practice device 10 is shown . the device 10 is comprised of a first planar upper section 12 and a second planar lower section 14 . each section has an upper surface and a lower surface , a first end and second end , and side edges . the upper section 12 has a passage 40 therethrough at a pre - determined location . opposed upstanding parallel side walls 16 are formed on the upper surface of the sections 12 , 14 attached to the side edges . a first end wall 18 with a front facing , back facing and top facing is integrally formed on the second end of the upper section 12 with the parallel side walls 16 . a second end wall 20 may be integrally formed on the first end of the lower section 14 perpendicular to the side walls 16 of the lower section 14 . alternately , a passage is defined when the second end wall 20 is removed . the lower surface of the first end of the upper section 12 is attached to the second end of the lower section 14 via hinge means 42 , and in the first position of the hinge means 42 the sections 12 , 14 are parallel to form an integrated putting surface . the hinge means 42 permits the sections 12 , 14 to be rotatable in relation to each other so that when in the second closed position of the hinge means 42 the upper surfaces of each section 12 , 14 are parallel . the hinge means 42 are preferably hinge bosses with complementary hinge pins . as illustrated in fig5 , the device 10 can be folded for transport or storage . a partition 50 is affixed to the upper surface of the upper section 12 and lower 14 . the partition 50 has a curvilinear outer surface , a planer base , front portion 52 , side portions 54 , and peripheral inner and outer edges along the front portion 52 and side portions 54 . the partition 50 is preferably made of wood composite . a channel 56 is defined by inner surfaces of the front portion 52 and side portions 54 of the partition 50 , and the upper surfaces of the upper section 12 and lower section 14 . the side portions 54 of the partition 50 are generally aligned perpendicular to each other . a first panel insert 60 and a second panel insert 70 , with upper and lower surfaces , are illustrated in fig2 . the inserts are removeable and securely mountable to the upper section 12 and lower section 14 in the defined provided channel 56 . the first panel insert 60 has a peripheral front edge 62 of predetermined shape to mount securely against the front portion 52 of the partition 50 , and peripheral side edges 64 to securely abut against the side portions 54 of the partition 50 . the second panel insert 70 has a peripheral front edge 72 , peripheral side edges 74 and a peripheral rear edge 76 . the front edge 72 of the second panel insert 70 abuts against a rear edge 66 of the first panel insert 60 . the first panel insert 60 has a passage 68 complimentary with the passage 40 of the upper section 12 . simulated turf material 22 , such as felt , is secured to the upper surface of the first panel insert 60 and the upper surface of the second panel insert 70 . the material provides consistent putting surface for practice . it should be recognized that different coverings can be installed to provide a variety of undulations and a variety of thicknesses . thus , the surfaces can be provided to simulate actual putting conditions for the user . for an example , the turf material on the first panel insert 60 may be angled to simulate a break in the putting surface , while the second panel insert 70 has a flatter composition . the passage 68 of the first panel insert 60 is aligned with the passage 40 of the upper section 12 to define a cup opening to allow golf balls to exit from the putting surface . a rim 28 having a top surface and a lower surface is integrally formed in the opening . insert members 26 having a top surface and a lower surface , turf material 22 secured to the top surface , and having a hole therethrough , are mountable on the rim 28 . the apertures of the insert members 26 have alternate diameters to provide a variety of targets for the cup opening . the insert members 26 thus allow more of a challenge for a player to make a practice putt . as illustrated in fig7 , a cup 80 is detachably mounted to the lower surface of the upper section 12 . a frame 82 comprised of side walls and a base wall , protects the cup . when mounted the panel inserts 60 , 70 provide an elevated surface relative to the remainder of the upper section 12 and the lower section 14 . a slot 24 is defined between the outer perimeter of the partition 50 , and the end wall 18 of the upper section 12 and the side walls 16 of the lower section 14 and upper section 12 . any golf balls exceeding the perimeter of the partition 50 are propelled into the slot 24 , and either return to the base of the device 10 because of the elevation , or are retrieved by the player . by having the elevated panel inserts , putting accuracy and putter alignment , are more readily taught . opposed elevation adjustment means 30 are provided to allow the user to elevate the putting surface of the device 10 as desired . the adjustment means 30 are secured to the upper section 12 . the preferred method of adjustment means 30 is illustrated in fig5 , and is comprised of an outwardly threaded rod 32 with a knob 34 at a first end and a round head nut 36 at a second end . the rod 32 is placed through a threaded brass insert 38 mounted in a bore formed in the side walls 16 of the upper section 12 . the brass insert 38 securely engages with the rod 32 to stabilize movement . the device 10 is raised and lowered by turning the knob 34 . as illustrated in fig1 - 2 and 6 , support platforms 90 are provided upon which to mount the adjustment means 30 . the platforms 90 have lower surface and upper surface , and are generally rectangular shaped . the upper surface of the platform has integrally formed indentations 92 therein , to securely engage with the head nut 36 of the elevation means 30 . the lower surface of the platform 90 is in contact with ground surface . when combined the elevation means 30 and platforms 90 provide alternate settings for the slope of the putting surface . adjustments can be made to compensate for uneven ground surfaces , and the adjustment means 30 on one side of the device 10 can be raised or lowered , simulating a break in the putting surface . each elevation means 30 can be independently to adjust the angle of the slope . in use a player stands at the first end of the lower section 14 after adjusting the elevation of the putting surface . the player can retrieve the golf balls after successful putting the ball through the cup opening . it can readily be seen that when the golf balls enter the slot 24 after leaving the turf material 22 on the panel inserts 60 , 70 because of errant putts , that the slope of the device 10 will return the balls to the golfer at the base . with respect to the above description then , it is to be realized that the optimum dimensional relationships for the parts of the invention , to include variations in size , materials , shape , form , function , and manner of operation , assembly and use , are deemed readily apparent and obvious to one skilled in the art , and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention . therefore , the foregoing is considered as illustrative only of the principles of the invention . further , since numerous modifications and changes will readily occur to those skilled in the art , it is not desired to limit the invention to the exact construction and operation shown and described , and accordingly , all suitable modifications and equivalents may be resorted to , falling within the scope of the invention .
the present invention relates to a golf practice putting device comprised of a lower section and an upper section being rotatably attached via hinge means . panel inserts have a felt material or other turf like material thereon , and are mountable on the sections . openings are formed in the upper section and panel insert for golf balls to exit into a capture area . opposed elevation means are secured to the upper section . the elevation means allow the angle of the putting surface to be modified according the slope the player desires . platforms are securely engaged with the elevation means to provide stability balance .
