Abstract: A hurdle structure includes a transverse bar, two upright poles, two support rods, and a plurality of hinge mechanisms. Each of the hinge mechanisms is mounted between the transverse bar and each of the two upright poles, and between each of the two upright poles and each of the two support rods. Each of the hinge mechanisms includes a first pivot member, and a second pivot member pivotally connected with the first pivot member. Each of the hinge mechanisms further includes an adjusting unit mounted between the first pivot member and the second pivot member. The adjusting unit includes a locking member and a positioning member. The locking member is provided with a plurality of grooves. The positioning member is provided with a projection positioned in one of the grooves of the locking member.

Abstract: A sport training structure includes a plurality of brackets and a plurality of first pivot members connected with the brackets. Each of the first pivot members has two connecting portions. Two of the first pivot members are mounted between two of the brackets to construct a polygonal frame, with each of the two connecting portions of each of the first pivot members being pivotally connected with one of the two pivot ends of each of the brackets. In such a manner, the two of the brackets are pivoted about the two of the first pivot members, so that the polygonal frame is foldable.

Abstract: An exercising device includes two support seats and a holding member. Each of the support seats includes a transverse bar, a first mounting tube located on the transverse bar, and a second mounting tube located on the transverse bar. An angle is defined between the first mounting tube and the second mounting tube of each of the support seats. The first mounting tube of each of the support seats has an extension length different from that of the second mounting tube. The holding member includes a grip portion and two connecting portions located at two ends of the grip portion. Each of the connecting portions of the holding member is respectively inserted into any one of the first mounting tube and the second mounting tube of each of the support seats.

Abstract: An exercising bar assembly includes a holding unit and two opposite swinging units each removably mounted on the holding unit. Thus, each of the two swinging units can be removed from the holding unit when not in use to reduce the whole volume of the exercising bar assembly and to facilitate storage, packaging, carrying and transportation of the exercising bar assembly.

Abstract: A grip assembly for a jump rope includes a grip body having a first end formed with an open casing and a second end formed with a receiving space, a counter mounted in the casing, a cover mounted on the casing and abutting the counter to locate the counter between the casing and the cover, a pivot head rotatably mounted on the casing and connected with the counter to drive the counter, and a weight member mounted in the receiving space of the grip body. Thus, the counter can count and indicate the jump number of the jump rope so that the user can know the jump number exactly. In addition, the weight member provides a damping force to the user' arms so as to exercise the user's arms.

Abstract: A fitness equipment includes a cord having two ends each provided with a handgrip, a cord mounting cap, a mounting sleeve, a snapping member, and two end caps. The mounting sleeve presses and locks the snapping member onto the respective end of the cord. The cord mounting cap receives the mounting sleeve and the snapping member and is removably mounted on the handgrip. Each of the end caps is removably mounted on the handgrip. Thus, each of the two ends of the cord is provided with a handgrip so that the fitness equipment can function as a jump rope, and the handgrip can be used individually to function as a dumbbell after the handgrip is detached from the cord.
