Height-adjustable golf practice apparatus
View Patent ↗Disclosed is a golf practice apparatus. The golf practice apparatus includes a body part having, at the upper side thereof, a hole-cup hole into which a golf ball goes; and a lifting/lowering part which is connected to the lower side of the body part and which moves at least a portion of a region of the body part in the vertical direction, wherein the lifting/lowering part includes: a plurality of lifting/lowering units for pushing or pulling a portion of the region of the body part; and a driving unit for driving each of the lifting/lowering units.
1 . A golf practice apparatus comprising:
a body portion comprising a hole-cup hole, into which a golf ball goes, formed at an upper side thereof;
a lifting/lowering portion connected to a lower side of the body portion and configured to move at least a partial area of the body portion in a vertical direction; and
a control portion configured to control the lifting/lowering portion by using ground information input through an input portion,
wherein the lifting/lowering portion comprises:
a plurality of air cells arranged in a plurality of columns and rows and configured to push or pull the partial area of the body portion; and
an air pump configured to inject and remove air into and from each of the air cells,
the body portion comprises a plurality of bodies arranged in a plurality of columns and rows to correspond to the air cells,
the air cells respectively correspond to the bodies, respectively connected to middle areas of the bodies, and respectively moving the bodies in the vertical direction,
the ground information comprises a plurality of pieces of partition information of a ground partitioned based on the plurality of columns and rows of the air cells,
each of the plurality of pieces of partition information comprises height information of the partitioned ground,
the control portion is configured to control the air cells by using the height information,
each of the bodies comprises:
a sliding groove recessed inward;
a sliding protrusion located opposite the sliding groove and protruding outward;
an additional sliding groove located between the sliding groove and the sliding protrusion and recessed inward; and
an additional sliding protrusion located opposite to the additional sliding groove and protruding outward,
the sliding protrusion of each of the bodies moves in the vertical direction while inserted into an adjacent sliding groove, and
the additional sliding protrusion of each of the bodies moves in the vertical direction while inserted into an adjacent additional sliding groove.
2 . The golf practice apparatus of claim 1 , further comprising
the control portion configured to receive ground information of a field and control the air pump so that the body portion corresponds to the ground information.
3 . The golf practice apparatus of claim 2 , wherein
the ground information includes a plurality of pieces of partition information of a partitioned ground so as to correspond to an arrangement of the air cells, and
each of the plurality of pieces of partition information includes the height information of the partitioned ground.
4 . The golf practice apparatus of claim 3 , wherein
the control portion is configured to
control the air pump so that the air cells are lowered when height values of the air cells are greater than the height information, and
control the air pump so that the air cells are lifted when the height values of the air cells are greater than the height information.
