Description

FIELD OF THE INVENTION

[0001] The present invention relates to the technical field of sports equipment, in particular to a fitness device.BACKGROUND OF THE INVENTION

[0002] Improvement in people's life quality, such as taking a car while going out and taking an elevator to go upstairs while getting back home, causes people a decrease in quantity of motion, thus some people will choose to exercise on purpose, so as to enhance their physique. In early days, people always took exercise outdoors due to absence of equipment; however, if it is necessary to exercise some specific parts of a human body, such as the abdomen, an exercise is achievable by way of doing sit-ups. However, when an exercise is done by way of doing sit-ups, it is necessary to restrict feet with the help of an object, or press feet directly with the help of a person; moreover, uneven strength exerted to muscles may occur on both sides of the abdomen through this kind of exercise only together with stretch, so that the exercise results in an asymmetrical abdominal muscle profile worsening the appearance. For example, if it is necessary to exercise the leg muscles, an exercise is achievable by way of running, but running for a long time will cause some damage to the feet; moreover, since it is difficult for a nonexpert to master a correct running posture and method, the way of running makes the feet toe in or toe out; in addition, it is still necessary to achieve the exercise by way of only running outdoors, which is extremely inconvenient.

[0003] Therefore, the technical problem to be actually solved by the present invention is how to achievably assist in correctly mastering an exercise posture and exercising one or more muscles of a human body by way of proposing a fitness device.SUMMARY OF THE INVENTION

[0038] We shall describe the present invention in detail and completely by means of specific embodiments in combination with the drawings as follows.

[0039] As shown in Fig. 1, a fitness device proposed by the present invention includes a frame 1, a sliding rod group 5, a translation plate 2, a foot rod 3 and a handle rod 4. Wherein, two ends of the sliding rod group 5 are respectively fixed on the frame 1; the translation plate 2 is movably arranged on the sliding rod group 5 and moves on the sliding rod group 5; two ends of the handle rod 4 are fixedly connected to the frame 1; two ends of the foot rod 3 are movably connected to the frame 1 and move back and forth on the frame 1.

[0040] As shown in Figs. 1 and 4, the translation plate 2 includes a first plate assembly 201 and a second plate assembly 202 that are arranged side by side and slidably fit with the sliding rod group 5. A blocking bar 205 is detachably disposed on the first plate assembly 201 and the second plate assembly 202, it can function as a barrier and a support for the feet or the legs placed on the first plate assembly 201 and the second plate assembly 202, so as enhance safety during exercise.

[0041] As shown in Figs.4, 5 and 6, the blocking bar 205 is inserted into and fits with either of the first plate assembly 201 and the second plate assembly 202, one transverse groove 208 and two longitudinal groove 209 vertically intersected with each other to form two cross-shaped structures are further set on the first plate assembly 201 and the second plate assembly 202; a first insertion hole 206 is positioned at the intersection of the transverse groove 208 and longitudinal groove 209; the blocking bar 205 is provided with a first insertion rod 207, and a position-restricting rod 210 fitting with the transverse groove 208 / longitudinal groove 209 is arranged on the first insertion rod 207. The first insertion rod 207 is inserted into the first insertion hole 206 of one of the two cross-shaped structures, and the position-restricting rod 210 is positioned inside the transverse groove 208 / longitudinal groove 209.

[0042] As shown in Figs. 1, 4, 5 and 7, in an example, a connector 203 is arranged between the first plate assembly 201 and the second plate assembly 202, so as to make the first plate assembly 201 and the second plate assembly 202 move synchronously. In addition, after the connector 203 is removed, the first plate assembly 201 and the second plate assembly 202 of the translation plate 2 can move back and forth in the direction of both ends of the sliding rod group 5, respectively. As shown in Fig.7, the connector 203 may be designed to be a plate, thus the plate-shaped connector 203 can increase the area of the translation plate 2.

[0043] In another example, as shown in Fig. 11, the connector 203 may also be designed to be a long strip, which is only used to connect the first plate assembly 201 with the second plate assembly 202.

The hole is designed to be waist-shaped, so that the insertion structure between the second insertion rod 212 and the second insertion hole 211 has an appropriate adjustment range without need of complete alignment, making insertion more convenient.

[0045] When taking exercise on a fitness device, an exerciser may choose to connect the first plate assembly 201 with the second plate assembly 202 together or use them separately. Therefore, it is necessary to design a mechanism that not only meets safety requirements of users, but also satisfy the exerciser in terms of fastness, simpleness and user-friendliness. Therefore, the fitness device of the present application has two unique structures to connect or lock the plate assembly; thus, the insertion block 213 can slide within the insertion groove 214 through the connector 203 to insert the two second insertion rods 212 into the second insertion hole 211. The connector 203 also has a non-slip surface and can be placed on central rails, so that the exerciser can sit down and take some exercise, as shown in Fig. 12. Another unique feature of the first plate assembly 201 and the second plate assembly 202 lies in possible arrangement of the blocking bar 205 on either of the two. This means that the exerciser can take exercise over again by way of simply placing the blocking bar 205 on two ends of the first plate assembly 201 / second plate assembly 202, as shown in Fig. 12.
