Description

Technical Field

[0001] The utility model relates to the field of entertainment, sports and fitness facilities, in particular to a fitness seesaw. Background Art

[0002] Conventional seesaws are constructed by placing an axle in the middle of a long, thick wooden board, which is then mounted on a support. When one end of the board rises, the other end falls, and when one end falls, the other end rises, repeating this process for fun. Two people, sitting opposite each other, take turns pushing against the ground with their feet, which can achieve a certain muscle and coordination training effect. However, this structure has the following drawbacks: when one end of the board rises, the user sitting at that end cannot continue to operate the board and can only continue pushing against the ground after that end falls. Furthermore, due to the principle of leverage, conventional seesaws require two people to simultaneously stand at both ends of the board to operate. When only one person is using the seesaw, the full training effect cannot be achieved, resulting in poor user experience. Utility Model Content

[0019] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0020] like Figure 1 The fitness seesaw shown includes a base, a supporting member, a seat 1 and a lifting drive device, wherein the supporting member has at least two ends.

[0021] A seat 1 is provided at each end of the carrier, and the seat 1 is arranged at a position close to the end of the carrier. The carrier is hinged to the base, and the position where the carrier is installed and in contact with the base is the hinge point of the carrier. The end of the carrier moves up and down with the hinge point as the rotating axis, and the hinge point is located between the two ends of the carrier. The lifting drive device is used to manually drive the end of the carrier to rise and fall. Preferably, each seat 1 is equipped with a lifting drive device.

[0022] Specifically in this embodiment, the supporting member is a straight board 2, which has roughly the same structure as the corresponding structure of the existing seesaw, and is a long flat square board. The hinge point is located at the center of the length direction of the straight board 2. Two long holes 3 are opened on both sides of the straight board 2 near the hinge point. The long holes 3 pass through the upper and lower surfaces of the straight board 2, and the two seats 1 are respectively arranged on the upper surface near the two ends of the straight board 2.

[0023] The base includes a base 4 and a pillar 5 erected on the base 4. As an optional solution, the pillar 5 can be directly fixed on the base 4, or the pillar 5 can be rotatably set on the base 4. The straight plate 2 is hinged at the upper end of the pillar 5. When the pillar 5 is rotatably set on the base 4, the straight plate 2 can rotate circumferentially on the horizontal plane together with the pillar 5.

[0024] The first and second limiting structures are arranged at intervals along the length direction of the pressure rod 6. The first limiting structure and the second limiting structure are respectively matched with the lower surface and the upper surface of the straight plate 2, and the first limiting structure or the second limiting structure abuts against the straight plate 2 to drive the straight plate 2 to be provided with one end of the seat 1 to rise or fall. Specifically, the first limiting structure and the second limiting structure are respectively arranged on the first cross bar group 7 and the second cross bar group 8 around the pressure rod 6. An operating armrest 9 is provided on one end of the pressure rod 6 hinged to the mounting slot, and a footrest structure is provided near the position of the pressure rod 6 hinged to the mounting slot. When the user is in use, the first cross bar group 7 and the second cross bar group 8 are both arranged perpendicular to the elongated hole 3. When the pressure bar 6 rotates, the first cross bar group 7 or the second cross bar group 8 abuts against the lower side or upper side of the straight board 2 on both sides of the elongated hole 3. When the user is in use, he steps on the footrest structure 10 with both feet and grasps the operating armrest 9 with both hands to push the pressure bar 6 forward or pull it backward. When the pressure bar 6 is pushed forward, the first cross bar group 7 below the elongated hole 3 lifts the straight board 2 upward, and the seat 1 where the operator is located moves upward, and the seat 1 of the other user at the other end moves downward. When the pull rod is pulled backward, the second cross bar group 8 above the elongated hole 3 presses the straight board 2 downward, and the seat 1 where the operator is located moves downward, and the seat 1 of the other user at the other end moves upward. The user and the operator can also simultaneously operate the pressure bar near themselves to make the other party's seat 1 rise or fall, thereby achieving the effect of mutual wrestling, increasing confrontation and fun.

[0025] Implementation method 2:

[0026] like Figure 2 As shown, the difference between this embodiment and embodiment 1 is that the base includes a conical platform 11 and a ball head seat 12 arranged on the conical platform 11. The conical platform 11 is a structure that is wide at the bottom and narrow at the top. The conical platform 11 can also be replaced by a round platform. The ball head seat 12 is fixedly installed on the top of the conical platform 11, and a universal wheel 18 is installed at the bottom of the conical platform 11. The top of the ball head seat 12 has a ball. The center point ball of the multi-head rod is hinged on the ball on the ball head seat 12, that is, the multi-head rod can use the ball head seat 12 as a fulcrum to make the end move up and down or rotate horizontally.

[0027] The supporting member is a multi-headed rod, which has a center point and multiple transverse arms 13 extending outward from the center point. The multiple transverse arms 13 are arranged at equal angles, that is, the angle between two adjacent transverse arms 13 is the same. For example, when the number of transverse arms 13 is 4, the angle between two adjacent transverse arms 13 is 90°. When the number of transverse arms 13 is 3, the angle between two adjacent transverse arms 13 is 120°. In this embodiment, the number of transverse arms 13 is 2, and the two transverse arms are located on the same straight line. The center point is the hinge point.

[0028] In this embodiment, the lifting drive device is a swing rod 14, which has a rod body, an operating armrest 9, a footrest structure 10 and a roller 15. The roller 15 is arranged at one end of the rod body, and the operating armrest 9 is located at the other end of the rod body. The middle part of the rod body is hinged on the transverse arm 13. Specifically, hinge blocks 16 are provided on both sides of the width direction of the transverse arm 13. A mounting box 17 is also fixed on the swing rod 14. Hinge holes are provided on both sides of the mounting box 17. The hinge blocks 16 are embedded in the hinge holes. The mounting box 17 is rotated on the transverse arm 13 with the hinge block as the axis. When the mounting box 17 rotates, it drives the swing rod 14 to rotate. At this time, the roller 15 is rolled on the outer circumference of the conical platform 11. When the roller 15 rolls on the outer circumference of the conical platform 11, the swing rod 14 acts in the opposite direction to make the transverse arm 13 rise or fall, thereby driving the transverse arm 13 to be provided with the end of the seat 1 to rise or fall.

[0029] Implementation method three:

[0030] like Figure 3 As shown, the difference between this embodiment and the second embodiment is that the number of transverse arms 13 is 3, and each transverse arm 13 is installed corresponding to a seat 1. This embodiment can be used by three users at the same time. Three people sit on the seat 1 and drive each transverse arm 13 to rise or fall by operating the armrest.
