Golf practice device

A golf practice device comprising an inclined ramp on which to place a golf ball to determine its roll in order to measure the speed of a green, wherein the device (1) comprises:

• a main body (2) with rectilinear development provided with a first pair of rails (20) spaced apart by a predetermined value so as to define a guide for rolling the ball;
• a base body (3), also provided with a second pair of rails (30) spaced apart by a predetermined value so as to define a guide for rolling the ball and hinged to said main body (2) so as to vary its configuration with respect to the main body to assume an open or use configuration in which it defines an obtuse angle with the main body (2) and a closed or rest configuration in which it is rotated so as to overlap the main body (2) or adjacent to the latter;
• and
• a support element (4) having hinged ends at a first end of the support element, and, free ends (44) at a second end of the support element, opposite to the first end, the hinged ends being hinged to said main body (2) so as to vary a configuration of the support element with respect to the main body to assume an open or use configuration in which the support element defines an angle with the main body (2) and one of its free ends (44) defines a support point and a closed or rest configuration in which the support element is rotated so that said main body (2) is superimposed on the support element or adjacent to the support element,
• wherein a width (D3) of said base body (3) is greater than a width (D2) of said main body (2) so as to accommodate the main body (2) at an interior of the base body (3) when the device (1) is in the closed or rest configuration.
