A golf mat including a base mat with a circular recess having an artifical turf at the bottom, a circular driving mat which has an artificial turf on its top surface and is rotatably fitted in the circular recess of the base mat by a pin, and an auxiliary plate installed under the driving mat. Each time a ball is hit off the driving mat, the driving mat rotates so that the entire surface of the driving mat is used evenly.

A golf ball playing surface assembly includes a plurality of different mats having different surfaces for simulating different golf playing surface conditions. A playing surface in a golf simulator, hitting bay or practice area is provided with a rectangular recess of predetermined depth, length and width. The mats have different piles for simulating different playing surface conditions, and can be placed side by side in any selected configuration in the recess to cover at least a major portion of the recess area. The depth of the recess is substantially equal to the height of at least some of the mats, so that a hitting surface is provided which is substantially flush with the surrounding floor area. Different combinations of mats can be placed in the recess to simulate different playing conditions.

A golf shot practice apparatus with a flat base, a flat support board disposed over said base having a simulated turf towards one end thereof and a step mat towards the other end thereof. Interposed between the base and support board is a universal mechanism including a support cylinder extending upward from the base, a curved plate shaped like the lower portion of a sphere disposed between said support cylinder and the support board under the step mat. The curved plate engages the support board under the step mat. Engaging the inside of said curved plate is a disc affixed to an axial rod. Coupled to the rod are control elements to lift the rod and disc to alter the altitude in space of the curved plate so as to incline the support board at any angle desired with flixing elements including fixing inner and outer cylinders engaging the fixing rod and lowering the rod so the disc engages the curved plate in a desired position. Coupled to the fixing elements is a handle and alarm elements operatively responsive to the position of the handle to provide an alarm when the support board is not fixed.

A golf practice platform comprised of a deck marked off in a stance area surfaced with a non-skid coating, and with marginal areas surfaced with replaceable artificial turf simulating turf of fairway depth and of rough depth, there being a series of spaced tees adjustable as to height in the fairway turf area, and all of which is adjustably inclined from horizontal to a substantial slope simulating hillside slopes and upon which the golfer can practice strokes facing any side of the platform as circumstances require.

A training or exercising device, in particular for the practice of golf, includes a fixed stand and an orientable platform, a support and articulation member for supporting the platform relative to the fixed stand, and two actuating jacks forming support and articulation elements. The two jacks and the support and articulation member are arranged in a substantially symmetrical manner around the center of the platform.
