Abstract: A golf putting green apparatus comprises an elongate putting green surface flexible panel supported on spaced apart elongate side members which are pivotally mounted at an intermediate portion on first support legs. The side members are supported at a putting off end of the apparatus on independently height adjustable second support legs so that as the putting-off end of each side support member is raised or lowered an opposite cantilevered hole end of the side support member is lowered or raised respectively.

Abstract: A height-adjustable billiard table includes a table body and legs. The table body has a bottom portion. Securing plates are disposed at four corners of the bottom portion and have respective support screw rods secured thereto. Each support screw rod has a gear in the form of an umbrella disposed at a top end thereof. The legs have screw rod seats at top ends thereof for receiving the support screw rods that connect the securing plates to the top ends of the legs. A transmission shaft having opposed worms provided at two opposite ends thereof is disposed at the bottom portion of the table body to extend in a longitudinal direction. Two worm shafts are disposed at front and rear ends of the bottom portion of the table body. The worm shafts are transverse to the transmission shaft and parallel to each other.

Abstract: A golf putting training apparatus for allowing for putting stroke practice at a wide variety of angles is provided, which includes: apertures formed at opposite sides of one end of the plate body, where the cup is mounted, and at center of the other end of the plate body; caps fixed into the apertures, which mate with wrench insertion holes in artificial grass; and height adjusters installed in the caps, the height adjusters each including: a fixed tube body; a plurality of spiral tube bodies for height adjustment, which thread onto the fixed tube body; and a pointed earth spiral bar which threads onto a lowermost spiral tube body having a wrench groove therein, the earth spiral bar and the spiral tube bodies for height adjustment having arc-shaped projections on their respective tops, and the projections and the fixed tube body respectively having stoppers therein, by which the projections are stopped.

Abstract: A modular putting surface apparatus for creating an adjustable putting surface. Each module comprises a frame, a first and second end member, a center members and two surface members connecting the center member and the end members. The center member is adjustable up and down at each end to create a complex curved surface. Multiple independent support members allow the surface area to be sufficiently flexible so as to be adjustable and simultaneously rigid enough to support humans walking on the surface. Multiple modules are interconnected to for a larger putting surface. The entire surface area is covered with a cover material chosen for its putting characteristics so as to simulate putting on grass.

Abstract: The present invention provides devices, systems and methods for aiding a golfer in properly aligning his stance prior to hitting a golf ball at any one of a plurality of pre-sighted targets; the principal feature of the invention is a golf mat designed to be pivotally attached to a support surface and having a pattern of lines visible to the golfer, the pivotal lines and mat positioned with respect to a plurality of pre-sighted targets so the golfer may properly align has stance prior to hitting a golf ball at the target.

Abstract: A portable putting surface is formed of a plurality of separate panels each having opposite left and right side rails removably secured thereto. The side rails in turn have mating ends which are used to assemble the panels into a continuous surface. A continuous length of artificial grass or turf material (e. g., Astroturf, tm) is used to cover the panels to form a reasonably realistic putting surface. The side rails each include a slope adjusting screw, thus enabling the left and right sides of the surface, and different panels of the surface, to be adjusted independently of one another in infinitesimally small increments as desired. The present putting surface may be used to simulate side hill lies on a sloping green, and/or may be used to duplicate very closely the slope of any particular green, from any approach direction. The surface assembles and disassembles easily in a matter of a minute or so, and may be packed into an extremely small package for shipment or storage, as desired.

Abstract: Golf putting apparatus having a putting surface on which a plurality of support springs and corresponding screws are provided proximate the periphery of the putting surface for enabling the user to quickly and easily create, or selectively alter, undulations in the putting surface.

Abstract: A practice putting green which includes a generally planar slab of rigid light weight material;a foam rubber pad installed on the upper surface of said pad;a covering layer of artificial turf attached to an upper surface of said pad;at least one target hole in said turf layer and pad; andat least one variable contour installation comprising a sealed cavity in said rubber pad and means for selectively pressurizing said cavity to cause upward bulging of said turf layer to provide a variable contour putting surface.

Abstract: A golf putting practice device is provided which will enable a golfer to practice putts of varying distances in a small area. The device includes a base, a height indicator arm hingedly connected to the base, and a relatively short track (e.g., 6-7') along which a golfer putts. The track may be elevated at one end to a desired height and secured at that height to the height indicator arm. The height indicator arm is calibrated for the length of the track and the various heights to which the track is raised, such that when the track is raised to a certain height (e.g., 2'), a practice putt on the device will correspond to a putt of a desired distance (e.g., 30') on an actual putting green. The surface of the track can be altered to simulate a dry putting green or a wet putting green. Varying putting green conditions, i.e., varying frictional forces exerted against the ball by the putting green, can also be varied simply by varying the height to which the track is raised.

Abstract: An artificial golf green is designed for use at driving ranges. The target green structure is formed at an incline to provide users of the golf range the appearance of a much larger target surface due to the perspective effects when viewing an inclined object from a distance. The construction of the target green is sectional to facilitate transportation. The landing surface includes artificial turf and an energy absorbing pad for more realistic performance.

Abstract: A practice putting green has an upper surface of material which simulates the green of a golf course and a support which raises the material of the upper surface upon which the practice putting green is positioned. The practice putting green has a generally rectangular shape with long and short sides, and to simulate the slope of a putting green, a support under one of the long sides of the upper surfaces raises that long side of the upper surface to a higher elevation above the underlying surface than the opposing long side. One or more wedges are also provided which may be positioned below the support to create a more uneven playing surface.

Abstract: A modular golf putting platform is comprised of at least two platform sections interconnected together at abutment ends. Each platform section or semi-integral section without the carpet glued to the top wall has opposed side walls, end walls, and a top wall having an upper putting surface. A cup for receiving a golf ball is mounted under a hole formed in the upper putting surface of at least one of the platform sections. Support brackets are detachably secured to a lower edge of the side walls for supporting the platform sections on a support surface. A bracket connecting element is provided for interconnecting the brackets, and therefore the platform sections. The support brackets have height adjusting elements to align the upper putting surface of adjacent platform sections in a substantially common plane.
