Abstract: The present invention provides a golf mat for a golf practice which makes it possible to allow a player to have a correct posture when in an indoor golf practice, while giving a chance to practice a correct posture. The golf mat for a golf practice comprises a base member placed on a flat floor surface for a golf practice; and a plurality of absorption members which are secured on a lower surface of the base member and are absorbed on a flat floor surface, thus fixing the base member, so the base member does not move.

Abstract: A golf tee includes an elastic member, which supports a golf ball in the course of swing of a golf club and elongates for allowing an upper member to be bent with respect to a lower member, can be prevented from damages, which leads to a longer lifespan while saving a purchase cost. The height of a golf tee can be adjusted, and a golf tee can be reliably inserted in a ground. The golf tee according to the present invention includes an upper member for supporting a golf ball, a lower member for allowing an upper member from being bent at the time when an impact force is applied to the upper member and is inserted in a ground in the use of golf tee, an elastic member for elastically contacting the upper member with respect to the lower member, and a strong string connected with the elastic member and is fixed to the lower member.

Abstract: A double structure cup is disclosed, which is characterized in that a plurality of polygonal male protrusions are protruded from a bottom surface of the inner cup in a downward direction, and a plurality of concave protrusions are formed and engaged with the male protrusions on a bottom surface of the outer cup in an upward direction, so that as the male protrusions are engaged with the concave protrusions, the inner cup does not rotate along with the lid when the lid is rotated for opening and closing.

Abstract: A golf tee is able to decrease the number of parts, and an assembling process is simplified, and a manufacture and assembling work do not cost a lot, and an easier maintenance and a desired advertisement effect can be obtained. The golf tee comprises an upper body which has a spherical mounting surface formed on its upper surface for mounting a golf ball; a lower body which supports the upper body from a lower side with its lower end being sharp for an easier planting into a ground, with a rubber cord being installed so as to provide a certain tensional force so that the upper body is pulled all the time to be straight with respect to the lower body.

Abstract: Sport gloves are disclosed, which comprise a thumb insertion part and an index finger insertion part which are separated for independently inserting a thumb and an index finger, respectively; and an integrated insertion part for inserting the remaining three fingers together. The sport gloves make it possible to enhance a gripping force when a user wears gloves for gripping a stick or a rod shape member which is used for an exercise such as golf, ski, hockey, steel rod or something while preventing uneasy gripping between the neighboring fingers and slippery.
