The target device has i) a base flange portion received below the practice mat, ii) a stem portion extending upwardly from the base flange portion through the teeing aperture in the practice mat, and iii) a target portion supported at the top of the stem portion to simulate a golf ball to be struck during a practice swing. The base flange portion, the stem portion and the target portion are integrally and seamlessly formed with one another of a resilient material with a hollow passage arranged to be externally vented and collapsed upon impact by a swinging golf club. ## Claims ### Claim 1 A target device for use with a golf swing practice mat having a teeing aperture formed therein, the target device comprising: a base flange portion arranged to be received below the practice mat; a stem portion extending upwardly from the base in a longitudinal direction so as to be arranged to extend upwardly through the teeing aperture in the practice mat; and a target portion supported on the stem portion at a location spaced upwardly from the base flange, the target portion having an increased lateral dimension in relation to the stem portion; the base flange portion, the stem portion and the target portion being integrally and seamlessly formed with one another of a resilient material; and the stem portion including a hollow passage extending longitudinally therethrough which is externally vented such that the stem portion is readily collapsible under impact of a swinging golf club. ### Claim 2 (depends on 1) The device according to claim 1 wherein the hollow passage of the stem portion is externally vented adjacent a bottom end of the stem portion. ### Claim 3 (depends on 1) The device according to claim 1 wherein the hollow passage of the stem portion is externally vented at a bottom end of the stem portion through an aperture in the base flange. ### Claim 4 (depends on 1) The device according to claim 1 wherein the target portion is hollow. ### Claim 5 (depends on 4) The device according to claim 4 wherein the target portion is at least partially vented through the hollow passage of the stem portion. ### Claim 6 (depends on 4) The device according to claim 4 wherein the target portion is at least partially vented through at least one vent aperture in the target portion. ### Claim 7 (depends on 6) The device according to claim 6 wherein the target portion is vented through a plurality of apertures in the target portion. ### Claim 8 (depends on 1) The device according to claim 1 wherein the base flange extends radially outward from a bottom end of the stem portion about a full circumference of the stem portion. ### Claim 9 (depends on 1) The device according to claim 1 wherein target portion is arranged to be readily collapsible under impact of a swinging golf club. ### Claim 10 (depends on 1) The device according to claim 1 wherein the target portion includes a solid core portion having a greater thickness than a wall thickness of the stem portion. ### Claim 11 (depends on 10) The device according to claim 10 wherein a largest cross sectional dimension of the solid core portion is equal to or less than a dimension of the stem portion transversely to the longitudinal direction. ### Claim 12 (depends on 10) The device according to claim 10 wherein the target portion includes a hollow portion in proximity to the solid core portion. ### Claim 13 (depends on 10) The device according to claim 10 wherein the target portion includes a plurality of flexible protruding members which protrude outwardly from the solid core portion such that an overall dimension of the target portion including the protruding members is greater than a dimension of the stem portion transversely to the longitudinal direction. ### Claim 14 (depends on 1) The device according to claim 1 wherein the target portion includes an outer wall surrounding a hollow interior, the outer wall having a striking portion of increased thickness arranged to be contacted by a swinging golf club. ### Claim 15 (depends on 1) The device according to claim 1 wherein the target portion includes a hollow core portion and a plurality of flexible protruding members which protrude outwardly from the hollow core portion such that an overall dimension of the target portion including the protruding members is greater than a dimension of the stem portion transversely to the longitudinal direction. ### Claim 16 (depends on 1) The device according to claim 1 wherein the target portion is collapsible to a collapsed position in which a maximum dimension perpendicular to the longitudinal direction of the stem portion is equal to or less than a corresponding dimension of the stem portion. ### Claim 17 (depends on 1) The device according to claim 1 in combination with the practice mat wherein said maximum dimension is equal to or less than a diameter of the teeing aperture in the practice mat. ### Claim 18 (depends on 1) The device according to claim 1 in combination with the practice mat wherein a diameter of the stem portion is approximately equal to the diameter of the teeing aperture. ### Claim 19 (depends on 1) The device according to claim 1 in combination with at least one ground stake including a head portion and a ground penetrating portion arranged to be penetrated into the ground wherein the head portion is arranged to retain the base flange portion against the ground when the ground penetrating portion is penetrated into the ground. ### Claim 20 A golf swing practice system comprising a target device in combination with a practice mat, the practice mat comprising a pad of resilient material arranged to be supported on a foundation and including a teeing aperture extending therethrough between opposing top and bottom sides of the practice mat, and the target device comprising: a base flange portion arranged to be received between the practice mat and the foundation and spanning in a lateral direction by a width which is greater than the teeing aperture; a stem portion extending upwardly from the base in a longitudinal direction so as to extend upwardly through the teeing aperture in the practice mat; and a target portion supported on the stem portion at a location spaced upwardly from the practice mat, the target portion having an increased lateral dimension in relation to the stem portion; the base flange portion, the stem portion and the target portion being integrally and seamlessly formed with one another of a resilient material; and the stem portion including a hollow passage extending longitudinally therethrough which is externally vented such that the stem portion is readily collapsible under impact of a swinging golf club.
