Therefore, the skeleton unit 1 provided by the present disclosure can be rolled or unfolded, and is convenient to store.

The adjacent skeleton units 1 may be connected by the flexible main body 2 only, or the adjacent left joint seats 11A are hinged and the adjacent right joint seats 11B are hinged, so that the adjacent skeleton units 1 can rotate relatively, or the adjacent skeleton units 1 can be connected by the two ways at the same time, which is not limited herein. And every left lower holding surface and right lower holding surface coplane can make the running frame subassembly expand the back and can tile subaerial, and every left joint seat 11A touches ground with right joint seat 11B all to play the effect of support, improve the steadiness of running frame subassembly when using. Here, the plurality of frame units 1 are arranged at intervals in the longitudinal direction, and two cases are included, first, when the running frame assembly is in the unfolded state, the plurality of frame units 1 are arranged at intervals in the longitudinal direction, and second, when the running frame assembly is in the unfolded state, the plurality of frame units 1 are arranged in series in a contact manner, but when the running frame assembly is in the folded state, the adjacent frame units 1 are spaced.

There are various ways in which the flexible body 2 connects adjacent skeletal units 1 together, and according to some embodiments of the present disclosure, the flexible body 2 may be positioned over at least all of the connecting ribs 12, with the flexible body 2 extending in the longitudinal direction to connect at least all of the connecting ribs 12 together, with the upper surface of the portion of the flexible body 2 positioned over all of the connecting ribs 12 being planar and serving as a running surface. Like this, when realizing the connection function of flexible main part 2, lay the race board on the race frame subassembly after, because flexible main part 2 is located between connecting rib 12 and the race board, and the upper surface of flexible main part 2 is the plane, can improve and run the sense. Alternatively, the flexible body 2 may be constructed as a flat plate and cover at least over all of the connecting ribs 12, the connecting ribs 12 being fixed to the lower surface of the flat plate. In other embodiments, the flexible body 2 may also be configured in the form of a frame, a plurality of connecting strips, which is not limited herein.

According to an embodiment of the present disclosure, the flexible body 2 may include a left connection beam portion 21A, a right connection beam portion 21B, and a platen portion 29, the left connection beam portion 21A being connected to a left side of the platen portion 29, the right connection beam portion 21B being connected to a right side of the platen portion 29, a plurality of skeleton units 1 being fixed on a lower surface of the flexible body 2, wherein a left joint seat 11A of each skeleton unit 1 is fixed to the left connection beam portion 21A, a right joint seat 11B of each skeleton unit 1 is fixed to the right connection beam portion 21B, the platen portion 29 being supported on the connection ribs 12, and an upper surface of the platen portion 29 serving as a running surface. Like this, the left and right sides of skeleton unit 1 all is connected with flexible main part 2, can improve the connection stability between the adjacent skeleton unit 1, does benefit to the smooth roll-up of runner frame subassembly.

Alternatively, the distance between each of the left and right lower support surfaces and the running surface is equal so that each of the left and right lower support surfaces is parallel to the running surface when the flexible body 2 is in the unfolded state. In this way, when the fitness equipment such as a treadmill or a walker is used, the running board of the fitness equipment such as a treadmill or a walker is parallel to the ground. Of course, each left lower supporting surface and each right lower supporting surface can be coplanar and form an angle with the running platform, so that when the running machine or the walking machine and other fitness equipment are placed on the horizontal ground, an included angle is formed between the running platform and the horizontal ground, climbing running or walking or downhill running or walking of the running machine or the walking machine and other fitness equipment can be realized, and various exercise selections are provided for users. The disclosure is not limited thereto.

According to some embodiments of the present disclosure, the left and right connecting beam portions 21A and 21B each have a thickness greater than that of the platen portion 29, a first thickness difference is provided between the lower surface of the left connecting beam portion 21A and the lower surface of the platen portion 29, a second thickness difference is provided between the lower surface of the right connecting beam portion 21B and the lower surface of the platen portion 29, the left connecting beam portion 21A includes a left joint seat fixing portion divided into a plurality of left segments 22A of equal length in the longitudinal direction, the number of the left segments 22A is equal to the number of the left joint seats 11A, the lower surface of each left segment 22A is opened with a left receiving groove 23A, at least a portion of the corresponding left joint seat 11A is located in the left receiving groove 23A to restrict the position of the left joint seat 11A with respect to the flexible body 2 by the left segment 23A, the right connecting beam portion 21B includes a right joint seat fixing portion, the right joint seat fixing part is divided into a plurality of right segments 22B with equal length along the longitudinal direction, the number of the right segments 22B is equal to that of the right joint seats 11B, a right accommodating groove 23B is formed in the lower surface of each right segment 22B, and at least one part of the corresponding right joint seat 11B is positioned in the right accommodating groove 23B so as to limit the position of the right joint seat 11B relative to the flexible main body 2 through the right accommodating groove 23B. Wherein the connecting rib 12 is located below the deck portion 29 and provides support for the deck portion 29, the lower surfaces of the left and right connecting

beam portions

21A and 21B are lower than the lower surface of the deck portion 29, the left joint seat 11A is located below the left connecting beam portion 21A, and the right joint seat 11B is located below the right connecting beam portion, so that the lower surface of the connecting rib 12 is higher than the left and right lower support surfaces, and a mounting space is left for the endless tread 63. And, because flexible main part 2 self characteristic, make after long-term the use, there is the creep in the shape of flexible main part 2 itself, and left joint seat 11A also becomes flexible with flexible main part 2 junction easily, these, all can lead to left joint seat 11A to change for flexible main part 2's position, can help overcoming these harmful effects through setting up left holding tank 23A, do benefit to and keep left joint seat 11A for long time for flexible main part 2's position, equally, right holding tank 23B has the same function with left holding tank 23A, it is no longer repeated here, like this, can keep the relative position between skeleton unit 1 and the flexible main part 2 for a longer time, improve the steadiness of runner frame subassembly.

Alternatively, the first thickness difference and the second thickness difference may be equal, so that the thicknesses of the left joint seat connection portion and the right joint seat connection portion may be the same, thereby making the structural strengths of the left joint seat connection portion and the right joint seat connection portion the same, and having the same constraint force on the left joint seat 11A and the right joint seat 11B, which is beneficial for the structural strengths of the left side and the right side of the running frame assembly to be the same, and improving the stability of the running frame assembly.

Alternatively, since the left and right

connection beam portions
