Description

Multifunctional leg training machine

Technical Field

The invention relates to fitness equipment; in particular to a multifunctional leg training machine which can train different muscle groups of legs.

Background

Modern people usually use various exercise devices to strengthen muscles of specific parts in order to keep healthy and pursue a better body shape. In the early stage, the weight training mode aiming at the legs is to carry the barbell on the shoulders and complete the training of leg muscles by means of the parallel squat and lift actions, however, only local muscles can be trained by a single training action, no safety facilities exist in the training process, and users are very likely to be crushed by the barbell when the weight load is not enough.

To solve the above safety problem, Smith trainer (Smith machine) is born. The Smith trainer comprises a frame and a barbell fixed in a steel rail of the frame, and the steel rail is further provided with a plurality of grooves. The user can fix the barbell in the groove of the steel rail by only twisting the wrist, so that the risk that the user is crushed due to falling of the barbell is reduced, and the training safety is improved; however, the barbell is limited to vertical movement and the user can still train only local muscles.

In order to make the user able to perform variable squat and lift actions and achieve the effect of training different muscle groups, a multifunctional leg training device has been developed, which makes the body of the user able to perform horizontal and vertical mixed training exercises, such as squat (square) posture, thorny (lunge) posture or calf-lift (calf-rise) posture, by means of a frame and a loading mechanism which can slide vertically and horizontally on the frame, so as to allow the user to exercise the muscle groups at different parts of the leg.

Although the leg exercise machine described above allows the user to exercise in a lateral motion, the number of positions and muscle groups that the user can exercise is still very limited.

Another problem often encountered by users is: as the weight of the user increases or the training time increases, the user tends to bow the upper body involuntarily, which often causes sports injuries due to poor posture, but the conventional training machines cannot maintain the user in the correct posture, which is a serious concern for the user.

Disclosure of Invention

In view of the above, the present invention is directed to a multifunctional leg training machine, which enables a user to train different leg muscle groups.

In order to achieve the above object, the present invention provides another multi-functional leg training machine, comprising: a frame, which comprises a fixed frame and a movable frame, wherein the movable frame can move relative to the fixed frame; a load mechanism, which is arranged at the deviating end of the movable frame and provides downward load weight; the bottom plate is connected with the fixing frame and comprises a first part and a second part, and the first part and the second part are clamped at a preset angle or have a height difference.

The effect of the invention is that the first part and the second part are arranged at a preset angle or have a height difference, so that a user can train different muscle groups of legs when stepping on the first part of the bottom plate and when stepping on the second part of the bottom plate.

Another object of the present invention is to provide a multi-functional leg training machine, which can maintain the user in a correct posture for training.

Each movable frame 12 includes a main rod 121, a first sub-rod 122, a first handle 123 and a second sub-rod 124. The main rod 121 has a pivot end 121a and a deviation end opposite to each other, wherein the deviation end is provided with a second handle 121b, the pivot end 121a has a pivot hole (not shown) therethrough, and the pivot shaft 115 of the fixing frame 11 passes through the pivot hole, so that the main rod 121 is pivoted to the fixing frame 11 and can swing around the pivot shaft 115; one end of the first secondary rod 122 is connected to the main rod 121, and one end of the first secondary rod 122 is at a right angle to the offset end of the main rod 121; one end of the first grip 123 is fixed to the first sub-rod 122; the two ends of the second secondary rod 124 are respectively connected to the first secondary rod 122 and the main rod 121, so as to enhance the structural strength of the main rod 121 and the first secondary rod 122.

The supporting frame 13 is connected with the movable frame 12 and abuts against the fixed frame 11. The supporting frame 13 includes a supporting rod 131 and a pushing device (not shown); the support rod 131 has a connection portion 131a, a deflection portion 131b and a pivot portion between the connection portion 131a and the deflection portion 131b, and the support frame 13 is pivoted between the two second sub-rods 124 by the pivot portion, and the deflection portion 131b has a through hole (not shown in the figure); the pushing device is a pneumatic cylinder in this embodiment, but not limited thereto, and one end of the pushing device is connected to the main rod 121, and the other end of the pushing device has an extending rod 132 connected to the connecting portion 131a of the supporting rod 131 for driving the supporting rod 131 to pivot in a first direction relative to the movable frame 12.

The reset device 14 is operated to drive the supporting frame 13 to swing pivotally relative to the movable frame 12 in a second direction opposite to the first direction. In the present embodiment, the restoring device 14 includes a first link 141, a second link 142, a third link 143, a fourth link 144 and a cross bar 145. The first connecting rod 141 is pivoted to the top side of the main rod 121 of the movable frame 12, one end of which forms a grip end 141a, and the other end of which is pivoted to the second connecting rod 142; the third link 143 is pivotally connected to the first secondary rod 122 of the movable frame 12, one end of which forms a grip end 143a, and the other end of which is pivotally connected to the fourth link 144; the cross bar 145 passes through the through hole of the support bar 131, and both ends of the cross bar are connected to the second link 142 and the fourth link 144, respectively.

The weight mechanism 20 includes two weight elements 21, which are located below the offset ends of the main rods 121 of the movable frames 12 to provide downward weight.

The leaning block 30 is placed on the first rod 122 of the movable frame 12 for leaning against the back or the chest of the user, thereby avoiding the user from unbearingly bowing up and down with an increase in weight or an extension of the training time, maintaining the user in a correct posture for training, and reducing the possibility of sports injury caused by poor posture.

The bottom plate 40 is disposed on the ground and has a first portion 41 and a second portion 42, wherein the first portion 41 is connected to the fixing frame 11 and the stepping surface 411 is parallel to the ground, and the second portion 42 is connected to the first portion 41 and inclined upward, so that the stepping surface 411 of the first portion 41 and the stepping surface 421 of the second portion 42 form a predetermined angle therebetween.

Referring to fig. 2 and 3, when the multifunctional leg training machine 100 is not in use, the swing portion 131b of the supporting rod 131 is pressed against the positioning portion 112a of the fixed rod 112 to raise the movable frame 12, and the supporting rod 131 is in the first state P1.

Referring to fig. 4 and 5, the multifunctional leg training machine 100 is shown in use. When a user wants to use the multi-functional leg training machine 100 to train, the user only needs to use the shoulder to abut against the bottom side of the weight 21 and apply a force upwards, so as to pivot the movable frame 12 upwards, at this time, the supporting rod 131 will leave the positioning portion 112a of the fixed rod 112, at the same time, the pushing device drives the extending rod 132, and further pushes the top end of the supporting rod 131, so that the supporting rod 131 pivots relative to the movable frame 12 in the first direction with the pivot portion as the axis, and the swinging portion 131b pivots towards the vertical frame 111 to assume the second state P2 and can avoid the fixed rod 112, so that the movable frame 12 will not be interfered when moving relative to the fixed frame 11, and at this time, the user can shoulder the movable frame 12 to perform squat exercise training. In addition, the design purpose of the supporting rod 131 avoiding the fixed rod 112 in the second state P2 is to avoid the collision between the supporting rod 131 and the fixed rod 112 during the squat exercise of the user, thereby improving the safety of the user during exercise.

In addition, referring to fig. 2 to 5 again, when the supporting rod 131 changes from the first state P1 to the second state P2 and leaves the positioning portion 112a of the fixed rod 112, the cross rod 145 of the resetting device 14 is driven by the supporting rod 131 to move toward the stand 111, and the second link 142 and the fourth link 144 connected to the cross rod 145 also drive the second link 142 and the fourth link 144 to deflect and displace toward the stand 111, thereby driving the first link 141 and the third link 143 to swing. Since the first link 141 and the third link 143 are pivotally connected to the movable frame 12, the grip end 141a of the first link 141 is offset from the second grip 121b of the main rod 121 to the second position L2 from the first position L1, and the grip end 143a of the third link 143 is also offset from the end of the first grip 123 to the second position L2 'from the first position L1'.

In this way, as shown in fig. 6a to 6c, the user can press the chest or back of the leaning cushion 30 to perform the squat and lifting actions of different postures to exercise the muscles of different parts, and the first portion 41 and the second portion 42 of the bottom plate 40 form a predetermined angle therebetween, so that the user can exercise different muscles of the legs when stepping on the stepping surface 411 or the stepping surface 421 with different angles.

Then, when the user uses the multifunctional leg training machine 100, the user only needs to operate the handle end 141a to swing the first link 141 toward the second handle 121b, or operate the handle end 143a to swing the third link 143 toward the first handle 123, so as to return the first link 141 or the third link 143 from the second position L2, L2 'to the first position L1, L1', and then drive the rest of the connected links and the cross bar 145, and return the supporting bar 131 to the first state P1. More specifically, when the user finally exercises with the back against the back pad 30 (see fig. 6a or fig. 6c), the user can grip the grip end 141a and the second grip 121b with the hands, so as to return the first link 141 from the second position L2 to the first position L1, and then the user can pivot the support rod 131 in the second direction and return the support rod from the second state P2 to the first state P1 through the returning device 14, and at this time, the user slightly bends his/her knees to pivot the movable frame 12 downward, so that the user can make the support rod 131 abut against the positioning portion 112a without looking back at the movement of the support rod 131, and the movable frame 12 is in the unused raised position. On the contrary, if the user finally exercises with the chest abutting against the back pad 30 (as shown in fig. 6b), the user only needs to pinch the grip end 143a and the first grip 123 with hands to move the grip end 143a toward the first grip 123, so as to return the third link 143 from the second position L2 'to the first position L1', and then the restoring device 14 can also drive the supporting rod 131 to return from the second state P2 to the first state P1.

In addition, referring to fig. 7, if the supporting rod 131 does not return to the first state P1 yet, and the user bends his/her knees to pivot the movable frame 12 downward, the deflecting portion 131b of the supporting rod 131 will abut against the bearing surface 113a of the cross bar 113 and the positioning element 114 thereof, such as: when the supporting rod 131 approaches the first state P1, the deflecting portion 131b will abut against the positioning element 114a close to the fixed rod 112; when the supporting rod 131 approaches the second state P2, the swinging portion 131b will abut against the positioning member 114b, so as to incline the movable frame 12 at a predetermined angle for fixing, thereby effectively preventing the user from being injured by the movable frame 12 due to the above situation.

Similarly, during the training process, if the user falls over due to the weight load or other reasons, the movable frame 12 directly swings downwards due to the influence of gravity, and at this time, the swinging portion 131b of the supporting rod 131 will abut against the bearing surface 113a of the cross bar 113 and the positioning member 114c closer to the upright frame 111 to achieve the effect of fixing the movable frame 12, so as to prevent the user from being crushed by the movable frame 12 and the load mechanism 20 due to the above situation.

As shown in fig. 6c, since the first portion 41 and the second portion 42 of the bottom plate 40 form a predetermined angle therebetween, the user can exercise different muscles of the leg by stepping on the stepping surface 411 or the stepping surface 421. In order to allow the user to more fully exercise the leg muscles, the bottom plate can be modified as follows.

Referring to fig. 8, in order to illustrate the bottom plate 50 according to the second preferred embodiment of the present invention, the bottom plate 50 has a first portion 51 and two

second portions

52 and 53 connected to two sides of the first portion 51, wherein the first portion 51 is parallel to the ground and the first portion 51 and the

second portions

52 and 53 are respectively clamped at a predetermined angle. Alternatively, as shown in fig. 9, the bottom plate 60 according to the third preferred embodiment of the present invention includes two first portions 61, 61 ' and three second portions 62, 63 ', wherein the second portion 62 is located between the first portions 61, 61 ', and the second portion 62 and the first portions 61, 61 ' respectively have a height difference therebetween, the second portion 63 is connected to the first portion 61 and is sandwiched by a predetermined angle, and the second portion 63 ' is connected to the first portion 61 and is sandwiched by a predetermined angle. Of course, the bottom plate is not limited to the above, and the user can exercise different muscles of the leg as long as each plane of the bottom plate has a height difference or a clamping angle.

Referring to fig. 10, a multi-functional leg training machine 100' according to a fourth preferred embodiment of the present invention is disclosed, which is similar to the first preferred embodiment, except that: the multi-functional leg training machine 100' further comprises a plurality of first weight bars 15, second weight bars 16 and weight blocks 22. The first load bar 15 is fixed on the fixed frame 11, the second load bar 16 is fixed on the relative position of each movable frame 12, and the load block 22 is detachably connected on the first load bar 15 or the second load bar 16.

When using the multi-functional leg exercise device 100', the user can adjust the downward weight by changing the number of the weight blocks 22 on the second weight bar 16 to achieve a better weight exercise effect, and the remaining weight blocks 22 not connected to the second weight bar 16 can be connected to the first weight bar 15 to achieve a storage function.

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
