Sports fitness machine

The present invention relates to a sports exercise machine, and more particularly to an exercise machine that can be tilted and can be freely swayed.

Modern people are busy and busy. They usually have no extra time to go outdoors when they return home, and sometimes they can choose more ways when they are not in good weather. As a result, there are many different types of exercise machines that can be used indoors, which can be placed in a home, fitness center or gym for exercise and fitness.

In the past, traditional exercise equipment for exercising the arms, waist and abdomen included sliding rails, sliding members and limit members. It achieves the effect of exercise and fitness through reciprocating displacement in a single direction. However, such exercise machines can only exercise the muscles of a single part of the body and cannot meet the needs of modern people. In addition, some exercise machines are designed to have a large operating range, but they are often difficult to operate, and the center of gravity of such exercise machines is usually too high and cannot adjust the range of operation at will, so it is easy to cause sports injuries during use. Such as a strain, a sprain or a fall.

As can be seen from the above, there is currently no exercise fitness device that is practical, simple to operate, high in safety, and free to swing or position. Therefore, relevant industry players are seeking solutions.

Therefore, the present invention provides a sports exercise device that utilizes a positioning member to penetrate a positioning hole and a fixing hole at a specific position, so that the sliding member can be stably tilted to train a muscle group of a single part of the body. Furthermore, through the special curved track, the limiting member which is inserted through the curved track and fixed to the fixing hole of the positioning seat allows the user to freely swing the sliding member through the strength of the waist and the lower body during the operation. In addition, the curved track can limit the arc angle of the sliding member, preventing the user from being injured due to the excessive angle of the arc. In addition, the track pitch of the double sliding rod can lower the pivoting portion and bring the center of gravity closer to the sliding track, thereby promoting the stability and safety of the sliding member and the sliding member when moving or rotating.

One embodiment of the present invention is an exercise exerciser that includes a slide rail, a slide member, a slide member, and a limit member. The sliding member is limited to reciprocately displaced on the sliding rail, and the sliding member includes a fixing hole and a pivoting portion. The slider rotates the slider. The sliding member includes a centering positioning hole, a plurality of inclined positioning holes, a rotating shaft and a virtual extension line. The pivoting portion pivots the rotating shaft. The virtual extension line is perpendicular to the axis of rotation and intersects the centering hole.

The sliding rail 200 includes two sliding rods 210a, 210b, two upper stops 220a, 220b and two lower stops 230a, 230b. Two of the sliding bars 210a, 210b are arranged in parallel with each other and at a track pitch D1. Furthermore, the two upper stoppers 220a, 220b are respectively disposed at the upper ends of the two sliding bars 210a, 210b and below the two sliding bars 210a, 210b. The two upper stoppers 220a, 220b are used to stop the upward displacement of the sliding member 300. In other words, the sliding member 300 can only be displaced to the position of the upper stoppers 220a, 220b, and the two upper stoppers 220a, 220b are the same height from the ground. In contrast, the two lower stoppers 230a, 230b are respectively disposed at the lower ends of the two sliding bars 210a, 210b and above the two sliding bars 210a, 210b. The two lower stoppers 230a, 230b are used to stop the downward displacement of the sliding member 300, that is, the sliding member 300 can only be displaced to the lower position of the lower stoppers 230a, 230b, and the two lower stoppers 230a 230b is also the same height from the ground. As can be seen from the above, the slider 300 is reciprocally displaceable at the upper stoppers 220a, 220b and the lower stoppers 230a, 230b, and its stationary state (unused state) is that the slider 300 abuts against the lower stoppers 230a, 230b.
