TECHNICAL FIELD

The present disclosure relates to the technical field of fitness equipment, in particular to a leg training device.

BACKGROUND

At present, in the field of fitness equipment, kicking machine, as a common lower limb exercise equipment, is widely used in various fitness places and family fitness environments. The traditional kicking machine design usually includes a fixed base, a swinging arm and a roller pad for connecting the leg and the swinging arm. The user's leg strength drives the roller pad, and then drives the swing arm to swing, thus achieving the effect of exercising the lower limb muscles.

The existing U.S. Pat. No. 5,980,434 discloses an “Exercise apparatus with adjustable roller pads”. The motion radian of the swing arm of the kicking machine in this patent is mostly arc-shaped, with a swing range roughly ranging from 0° to 90°. Although this design can meet the exercise needs of users to a certain extent, there are some problems in the actual uses.

Specifically, because the trajectory of the swing arm is circular, the weight acting on the leg changes obviously from the beginning to the end. In the initial stage of swinging the swing arm, the weight borne by the leg is relatively light because of the small gravity; however, with the increase of the swing angle of the swing arm, the gravity effect is gradually enhanced, and the weight borne by the leg is also increased.

This uneven distribution of weight from the beginning to the end not only affects the exercise effect of users, but also may pose a potential threat to users' health. Especially in the later stage of swinging arm, due to the sudden increase of weight, the user's leg muscles and joints may bear excessive pressure, thus increasing the risk of injury.

As shown inFIG.1toFIG.6, an embodiment of the present disclosure provides a leg training device, which includes a support frame1, a seat5, a leg exercise component2, a load transfer component3and a counterweight bearer4. The seat5is provided on the support frame1, the leg exercise component2is rotatably connected to the support frame1and located at the front side of the seat5, and the counterweight bearer4is rotatably provided on the support frame1. One end of the load transfer component3is connected to the counterweight bearer4, and the other end of the load transfer component3is connected to the leg exercise component2.

In this embodiment, when the user sits on the seat5, the user lifts up the leg exercise component2by his legs, and the leg exercise component2drives the load transfer component3, which then drives the counterweight bearer4. A counterweight (not shown) is placed on the counterweight bearer4. With this configuration, when the user lifts the leg exercise component2, the counterweight bearer4can provide stable resistance to the leg exercise component2through the load transfer component3, so as to achieve the purpose of exercising the leg muscles of the user.

The counterweight bearer4includes a rotating rod41and a mounting rod42. One end of the rotating rod41is rotatably provided on the support frame1, and the mounting rod42is connected to the other end of the rotating rod41. The counterweight is a dumbbell plate, which can be sleeved on the mounting rod42to provide resistance to the leg exercise component2. If a user needs a heavier weight, a plurality of counterweight blocks can be sleeved on the mounting rod42.

It can be appreciated that the present application transfers the resistance of the counterweight bearer4to the leg exercise component2through the load transfer component3, thus facilitating the balanced and smooth lifting of the leg exercise component2, realizing the balanced transfer of the weight of the leg exercise component2from the beginning to the end, improving the user's experience and avoiding the user from being injured due to the sudden increase in weight.

Next, the specific structure of the leg exercise module2will be described in detail:

As shown inFIG.2, in one embodiment, the leg exercise component2includes a roller pad21, a link mechanism22and an adjusting mechanism23. Both of the link mechanism22and the adjusting mechanism23are rotatably disposed on the support frame1. The link mechanism22is detachably connected to the adjusting mechanism23, the roller pad21is in connected to the link mechanism22and located at the front side of the seat5, and the load transfer component3is fixedly connected to the adjusting mechanism23.

In this embodiment, after the user sits on the seat5, the user puts his legs on the bottom of the roller pad21. The roller pad21is connected to the link mechanism22, so that the roller pad21can rotate through the link mechanism22. As such, the user can lift the roller pad21forcibly, and the link mechanism22can simultaneously link the adjusting mechanism23to rotate, while the adjusting mechanism23rotates and pulls the load transfer component3, and the load transfer component3is rotated and lifted with a linkage with the counterweight bearer4to provide resistance to the roller pad21.

As shown inFIG.3, in one embodiment, the adjusting mechanism23includes an adjusting disc231, a rotating shaft233and a plurality of first bearings232. The rotating shaft233is connected to the support frame1, and the plurality of first bearings232are sleeved on the rotating shaft233. The adjusting disc231is sleeved on the plurality of first bearings232, the link mechanism22is detachably connected to the adjusting disc231, and the load transfer component3is fixedly connected to the adjusting disc231.

In this embodiment, when the user sits on the seat5and lifts up the leg exercise module2with both legs, the roller pad21and the link mechanism22will move upward. Because the link mechanism22is detachably connected with the adjusting disc231, when the link mechanism22moves upward, the adjusting disc231will be driven to rotate on the rotating shaft233. The rotation of the adjusting disc231will further pull the load transfer component3fixedly connected therewith. The other end of the load transfer component3is connected with the counterweight bearer4, therefore when the load transfer component3is pulled, the counterweight bearer4will also be pulled and move with it. The counterweight on the counterweight bearer4provides resistance for the user, and this resistance is transmitted to the user's leg through the load transfer component3and the adjusting mechanism23, thus realizing the exercise of leg muscles.

In an embodiment, a plurality of second bearings24are sleeved on the rotating shaft233, and the link mechanism22is sleeved on the plurality of second bearings24.

In this embodiment, the link mechanism22is sleeved on the rotating shaft233through a plurality of second bearings24, so that the link mechanism22and the rotating shaft233of the adjusting mechanism23have the same axis, thereby the link mechanism22drives the adjusting mechanism23to rotate more stably.

In an embodiment, the link mechanism22includes a first rod221, a second rod222and a bolt223. The roller pad21is connected to the first rod221, the first rod221is connected to the second rod222, the second rod222is sleeved on a plurality of second bearings24, and the bolt223penetrates the second rod222and is inserted into the adjusting disc231.

In this embodiment, when the user sits on the seat5and lifts the leg exercise component2upward by the leg force, the roller pad21and the first rod221will move upward accordingly. Because the first rod221is connected with the second rod222, the force exerted on the roller pad21and the first rod221is transmitted to the second rod222, so that the second rod222(and the second bearings24sleeved on it) rotates around the axis of the rotating shaft233, thereby realizing the lifting and rotation of the roller pad21. The arrangement of the bolt223ensures that the link mechanism22will not fall off the adjusting disc231during the rotation, which is beneficial to the stability of the link mechanism22driving the adjusting mechanism23to rotate.

In an embodiment, the adjusting disc231is provided with a plurality of spaced adjusting holes2311, and the bolt223can be inserted into any of the adjusting holes2311.

In this embodiment, the adjusting holes2311are provided around the rotating shaft233of the adjusting disc231. Since the link mechanism22and the rotating shaft233of the adjusting disc231also have the same axis, each adjusting hole2311is on the rotating track of the link mechanism22. Therefore, when the bolt223is inserted into different adjusting holes2311, the starting angle of the link mechanism22varies, that is, the starting angle of the roller pad21is changed, thereby meeting the different intensities of leg training of users.

In an embodiment, the load transfer component3includes a rope31and a guide wheel32. The guide wheel32is provided on the support frame1, and the rope31is wound around the guide wheel32. One end of the rope31is connected to the counterweight bearer4, and the other end of the rope31is connected to the leg exercise component2.

In this embodiment, the rope31is tightly wound around the guide wheel32, and the power and movement are transmitted by friction. When the adjusting mechanism23rotates, it will pull the rope31to move on the guide wheel32, and the guide wheel32can provide support and guide the movement of the rope31, ensure that the rope31keeps the correct path and tension in the transmission process, and avoid the rope31from loosening or excessive wear.

And a fixed pulley transmission mechanism is formed between the rope31and the guide wheel32, so that the stress on the two parts of the rope31at both sides of the guide wheel32is 1:1, thus ensuring that the weight of the counterweight bearer4is always and constantly transferred to the leg exercise component2, thus avoiding the influence of gravity change on the exercise effect and improving the user experience.

In this embodiment, the number of guide wheels32is one, but in other possible embodiments (not shown in the figure), the number of guide wheels32may be multiple, thus forming a fixed pulley block, further improving the moving convenience of the rope31.

In one embodiment, the support frame1is provided with a fixed seat13, and the counterweight bearer4can be supported on the fixed seat13.

In this embodiment, when the load transfer component3does not pull the counterweight bearer4, the counterweight bearer4is supported on the fixed seat13, and when the load transfer component3pulls the counterweight bearer4to rotate, the counterweight bearer4is separated from the fixed seat13. In this way, when the load transfer component3does not pull the counterweight bearer4, the counterweight bearer4is stably supported on the fixed seat13. Therefore, the counterweight bearer4can be prevented from shaking or tilting when it is not stressed, and ensure the static stability of the leg training device.

In one embodiment, the support frame1includes a bottom frame11and an inclined frame12, which is obliquely provided on the bottom frame11. The leg exercise component2, the load transfer component3and the counterweight bearer4are all provided at the top end of the inclined frame12.

In this embodiment, the support frame1consists of a bottom frame11and an inclined frame12. The bottom frame11serves as a solid foundation of the whole structure and provides necessary supporting force. The inclined frame12is obliquely provided on the bottom frame11to form an upward inclined surface. With this configuration, the spatial layout and stress situation of the whole leg training device can be optimized. At the top end of the inclined frame12in the inclined direction, there are three key components, namely the leg exercise component2, the load transfer component3and the counterweight bearer4. The leg exercise component2enables the counterweight bearer4to rotate smoothly along the inclined frame12under the pull of the load transfer component3, thus ensuring the fluency and stability of the movement. The rope31is wound around the guide wheel32, with one end connected to the counterweight bearer4and the other end connected to the leg exercise component2, and the rotation of the counterweight bearer4is realized through the transmission of the rope31. The counterweight bearer4is directly placed on the fixed seat13at the top end of the inclined frame12, and remains stable when the rope31is not pulled. When the rope31is pulled, the counterweight bearer4is separated from the fixed seat13and starts to rotate along the inclined frame12. This configuration not only ensures the compact structure and reasonable stress of the leg training device, but also greatly improves the convenience and safety of use.

In one embodiment, the seat5includes a seat cushion51and a back cushion52, one side of which is rotatably provided on the support frame1, and the seat cushion51is connected to the other side of the back cushion52.

In this embodiment, the seat cushion51is a plane part that the user directly contacts when sitting, providing a comfortable sitting feeling. The back cushion52is a component on the back of the seat5to support the back of the user. One side of the back cushion52is provided on the support frame1in a rotatable connection manner, so that the angle of the back cushion52can be adjusted within a certain range to meet the needs of different users for the back support angle.

The leg training device provided by the present disclosure has high safety. When a user lifts the roller pad21by his legs, the roller pad21transfers the resistance of the counterweight bearer4through the load transfer component3, so that the weight of the roller pad21is constant in the process of being lifted from the bottom to the top, and there will be no sudden increase in the weight of the roller pad21during lifting, thus ensuring the safety of the user during training and avoiding muscle strain of the user.
