Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a free-trajectory Smith machine compound training device. Background Technology

[0002] The Smith machine is a fixed-track compound training machine widely used in gyms. Its function is to confine the barbell to a vertical track, combining safety and versatility. The fixed track and safety lock design ensure safety, making it suitable for solo training without a spotter; it requires less focus on balance and coordination, is easy to use, and suitable for fitness beginners; it can be used for various training movements such as squats, bench presses, shoulder presses, and deadlifts.

[0003] In existing technology, the Smith machine consists of an upright metal frame and a horizontal bar. The bar moves on a preset track via a roller system, and the trajectory is mostly vertical. In order to better match the human body in barbell pressing movements such as squats, bench presses, and shoulder presses, some models adopt a fixed tilt design, while a few models adopt an adjustable tilt design to change the movement trajectory and adapt to the human body's natural movement pattern.

[0004] However, users with different arm lengths, torso proportions, and thoracic spine flexibility will have different motion trajectories when pushing, and a fixed tilt angle may still cause joint wear and tear; moreover, the motion trajectory required for different training movements is also different, and the existing Smith machine cannot adjust the machine to match different motion trajectories according to different training needs, making it difficult to achieve the expected training effect. Utility Model Content

[0005] To address the problem that existing Smith machine training trajectories are fixed and cannot adapt to the various movement trajectories required during training, this invention provides a Smith machine composite training device with a free trajectory.

[0006] This utility model provides a free-trajectory Smith machine compound training device, which adopts the following technical solution: A free-trajectory Smith machine compound training device includes a support frame, a horizontal movement device, a lifting mechanism, and a safety mechanism. The lifting mechanism includes a vertical bar, an Olympic bar, and a vertical slider. The vertical bar slides horizontally on the support frame via the horizontal movement device. The vertical slider slides on the vertical bar. The Olympic bar is mounted on the vertical slider. The safety mechanism is mounted on the Olympic bar and is used to connect to the support frame when the machine stops moving. The horizontal movement device includes a horizontal guide rail, a horizontal slider, and a rectangular connecting plate. The horizontal guide rail is mounted on the support frame. The horizontal slider is slidably connected to the guide rail. The rectangular connecting plate connects the horizontal slider and the vertical bar.

[0007] By adopting the above technical solution, during training, when the trainee uses the Olympic bar to perform a lifting motion, the Olympic bar slides vertically along the upright bar, and the upright bar moves horizontally with the horizontal slider, matching the movement trajectory of the Olympic bar. This reduces the force applied to the human body, making the lifting motion of the Olympic bar conform to the natural movement trajectory of the human body. Through the above settings, the Olympic bar can move freely within the range of motion of the lifting mechanism and the horizontal moving device, no longer restricted by a fixed movement trajectory. It can move freely according to the natural movement pattern of the human body and personalized movement trajectory, making the training movements more natural and in line with the natural movement trajectory of the human body. This reduces joint pressure during training, thereby achieving adaptation to different needs of different groups of people and improving the applicability of the equipment.

[0008] Optionally, the safety mechanism includes a safety hook and a snap-on column. The safety hook is mounted on the Olympic rod and can rotate with the Olympic rod. The Olympic rod rotates on the vertical slider. The safety hook cooperates with the snap-on column to suspend the Olympic rod.

[0009] By adopting the above technical solution, when fatigue or problems occur during training, simply rotate the barbell to safely hang it on the buckle post via the safety hook, preventing injury from being crushed.

[0010] Optionally, the safety hook has a limit post on its side, which cooperates with the buckle post to limit the angle of rotation of the safety hook.

[0011] By adopting the above technical solution, when the suspension rod needs to be selected during training, the rod is rotated to a certain angle. After the limiting post abuts against the buckle post, it can be determined that the safety hook has been rotated into place, and the limiting post plays a positioning role, reducing safety problems caused by the safety hook not rotating into place or over-rotating, and enabling it to be hung more accurately on the buckle post.

[0012] Optionally, the snap-on column is mounted on the horizontal slider and moves synchronously with the horizontal slider and the column.

[0013] By adopting the above technical solution, the distance between the snap-on column and the safety rod remains constant. The safety rod can be moved to any position and the safety hook can be rotated to ensure that it is safely suspended on the snap-on column.

[0014] Optionally, the safety mechanism includes a limiting hook, which is installed on the upright and cooperates with the snap-on column to limit the vertical displacement of the upright.

[0015] By adopting the above technical solution, in the event that the Olympic rod accidentally falls off or malfunctions during training, the limiting hook can prevent it from falling and injuring the trainee or causing other losses.

[0016] Optionally, the horizontal guide rail has a circular upper section and an isosceles trapezoidal lower section, and the shape of the horizontal slider groove matches the shape of the horizontal guide rail's cross section.

[0017] By adopting the above technical solution, the load-bearing capacity of the horizontal moving device is improved. The upper circular guide rail ensures smooth horizontal sliding of the device, while the inclined surface of the lower trapezoidal structure provides certain support, thereby improving the load-bearing capacity and reducing the deformation of the horizontal guide rail caused by the load.

[0018] Optionally, the support frame may also be equipped with a bird stand, a folding bench, a rowing frame, a pull-up frame, and a counterweight structure.

[0019] By adopting the above technical solutions, more diverse training programs can be completed, saving space and improving equipment utilization.

[0020] Optionally, a roller is installed on the fifth connecting plate of the lifting mechanism, which abuts against and rotates relative to the support frame. The support frame has a guide groove, and the pulley moves horizontally within the guide groove.

[0021] By adopting the above technical solution, the stability of the horizontal moving device during operation can be increased, the lateral stress borne by the horizontal guide rail during the movement of the horizontal slider can be shared, and the overall safety and stability can be improved.

[0022] Optionally, the two snap-on posts are respectively installed on the sides of the two posts that are opposite to or close to each other, and the safety hook and the limiting hook both extend to the front side of the snap-on posts and cooperate with the snap-on posts to be suspended on the snap-on posts.

[0023] By adopting the above technical solution, the distance between the upright and the snap-on column can be shortened, the overall width of the training equipment can be reduced, the floor space occupied can be decreased, and space can be saved.

[0024] In summary, this utility model has at least one of the following beneficial technical effects: 1. It solves the problem of the fixed movement trajectory of the traditional Smith machine, which does not conform to the natural movement trajectory of the human body. It allows the bar to move freely, which is closer to the training method of free weight. This makes the training movements more natural, conforms to the natural movement trajectory of the human body, and reduces joint pressure during training.

[0025] 2. The safety hook and limit hook provide double safety protection. When you are exhausted or encounter a problem, you can simply rotate the barbell slightly to safely hang it on the hook and prevent it from being crushed.

[0026] 3. While allowing multi-directional movement, the track itself still provides a certain degree of balance assistance, reducing the risk of injury due to loss of balance during heavy weight training.

[0027] 4. The starting position and angle of the bar can be easily adjusted to simulate various training movements, basically covering compound training of the main muscle groups of the whole body, saving space and improving the utilization rate of the equipment. Attached Figure Description

Detailed Implementation

[0030] The following combination Figures 1 to 5 The present invention will be described in further detail below.

[0031] This utility model discloses a free-trajectory Smith machine compound training device.

[0032] Example 1: Refer to Figures 1 to 4 A free-trajectory Smith machine compound training device mainly includes: a support frame 100, a horizontal moving device 200, a lifting mechanism 300, and a safety mechanism 400. The horizontal moving device 200 is detachably mounted on the support frame 100, the lifting mechanism 300 is detachably mounted on the horizontal moving device 200 and can move with the horizontal moving device 200, and the safety mechanism 400 is mounted on the lifting mechanism 300 to ensure the safety of the lifting mechanism 300.

[0033] The support frame 100 includes two long crossbeams 110, two square frames, and a middle crossbeam 140. The directional frame is composed of three columns 120 and two cross braces 130 spliced ​​together. The two cross braces 130 are spaced apart from the three columns 120, and the cross braces 130 are located at the upper end of the columns 120. Two middle crossbeams 140 are spaced apart at the end of the three columns 120 near the ground. The columns 120, cross braces 130, and middle crossbeams 140 are detachably connected by bolts. The long crossbeams 110 are located on both sides of the width direction of the two square frames and are bolted to the top of the square frames.

[0034] The horizontal moving device 200 includes a top horizontal moving mechanism 210 and a bottom horizontal moving mechanism 220. The top horizontal moving mechanism 210 includes an optical axis 211, a first connecting plate 212, a connecting block 213, a horizontal slider 214, and a rectangular connecting plate 215. One end of the optical axis 211 is bolted to the first connecting plate 212, and the other end is bolted to the connecting block 213. The side of the first connecting plate 212 is C-shaped, and the opening shape matches the cross-section of the long crossbeam 110. In the middle of a long crossbeam 110 at the top of the support frame 100, a square connecting block 213 with the same width as the cross-sectional width of the long crossbeam 110 is installed in the middle of another long crossbeam 110 at the top of the support frame 100 by bolts. A horizontal slider 214 is installed on the optical axis 211 and slides horizontally with the optical axis 211 as a guide. A rectangular connecting plate 215 with the same length as the long crossbeam 110 is welded to the horizontal slider 214 and moves with the horizontal slider 214. The rectangular connecting plate 215 is used to connect the lifting mechanism 300.

[0035] The bottom horizontal moving mechanism 220 includes two horizontal guide rails 221, two extended sliders 222, two second connecting plates 223, and two third connecting plates 224. The horizontal guide rails 221 have a circular upper section and an isosceles trapezoidal lower section. The base of the horizontal guide rails 221 has evenly arranged through holes that are bolted to the horizontal surface of the second connecting plates 223. The sides of the second connecting plates 223 are C-shaped, and the opening shape matches the cross section of one of the middle crossbeams 140. The vertical surface has an elongated through groove, which is bolted to the support. On the middle crossbeam 140 at the bottom of the support frame 100, the extended slider 222 is mounted on the horizontal guide rail 221. The groove shape of the extended slider 222 matches the cross-sectional shape of the horizontal guide rail 221. The side of the third connecting plate 224 is C-shaped, and the opening shape matches the cross-section of the extended slider 222 and the length is the same as that of the extended slider 222. The third connecting plate 224 is mounted on the extended slider 222 by bolts and moves with the extended slider 222. The third connecting plate 224 is used to connect the lifting mechanism 300. The same applies to the other side.

[0036] The lifting mechanism 300 includes two uprights 320, an Olympic rod 310, two vertical sliders 330, two Olympic rod sleeves 340, two fourth connecting plates 350, and two fifth connecting plates 360. The uprights 320 are long rods with a circular cross-section. The upper end of the upright 320 is fixedly installed on a horizontal plate below the fourth connecting plate 350, and the lower end of the upright 320 is fixedly installed on a horizontal plate of a third connecting plate 224. The fourth connecting plate 350 has a Z-shaped side with two horizontal plates and one vertical plate. The horizontal plate above the fourth connecting plate 350 is bolted to the horizontal plate of the fifth connecting plate 360. The fifth connecting plate 360 ​​has an L-shaped side with one horizontal plate and one vertical plate, with the horizontal plate at the bottom and the vertical plate at the top. A rectangular connecting plate 215 is bolted to the fifth connecting plate 360. The vertical slider 330 is mounted on the upright 320 and slides vertically with the upright 320 as a guide. The sleeve 340 is rotatably connected to the vertical slider 330 through a bearing.

[0037] Safety mechanism 400 includes two snap-fit ​​posts 410, two safety hooks 420, and two limiting hooks 430. The snap-fit ​​posts 410 are square tubular structures with cylindrical snap-fits evenly arranged from top to bottom. The upper end of the snap-fit ​​post 410 is welded to a horizontal plate below the fourth connecting plate 350, and the lower end of the snap-fit ​​post 410 is welded to the horizontal portion of the third connecting plate 224. The cylindrical snap-fits are parallel to the rod 310. The snap-fit ​​posts 410 are parallel to the rod 320, and the spacing between them is the same as the length of the hook portion of the safety hook 420. The safety hook 420 consists of a limiting post 421, a sleeve portion, and a safety hook portion. The sleeve portion of the safety hook 420 is fixed to the rod 310, preventing relative rotation or movement between them. The limiting post 421 is located on the side of the safety hook portion of the rod 310. Between the safety hook 420 and the snap-on column 410, the limiting post 421 engages with the side wall of the snap-on column 410 to limit the rotation angle of the safety hook 420. When the rod 310 is suspended, the rod 310 is rotated to a certain angle, and after the limiting post 421 abuts against the snap-on column 410, it can be determined that the safety hook 420 has been rotated into place, and the limiting post 421 plays a positioning role. The shape of the hook groove of the safety hook part matches the cylindrical snap-on on the snap-on column 120. The limiting hook 430 is divided into a limiting hook 430 sleeve part and a limiting hook part. The cross-section of the limiting hook 430 sleeve part is annular, and the inner wall diameter is the same as the cross-sectional diameter of the column 320. It is installed on the column 320 and its position is adjustable. The shape of the hook groove of the limiting hook part matches the cylindrical snap-on on the snap-on column 120, and the same applies to the other side.

[0038] The implementation principle of Embodiment 1 of this utility model is as follows: Before training, fix the two limit hooks 430 in the appropriate positions on the buckle column 410. During training, the trainee grips the Olympic bar 310 with both hands, moving it along the natural movement trajectory of the human body. As the Olympic bar 310 moves, it drives the vertical slider 330 through the Olympic bar sleeve 340, moving it vertically up and down along the column 320. The upper part of the lifting mechanism 300 is connected to the top horizontal moving mechanism 210 through the fifth connecting plate 360, and the lower part is connected to the bottom horizontal moving mechanism 224 through the third connecting plate 224. The horizontal slider 214 drives the entire lifting mechanism 300 to move back and forth along the optical axis 211 of the top horizontal moving mechanism 210 and the horizontal guide rail 221 of the bottom horizontal moving mechanism 220. When the training ends, the trainee is exhausted, or other problems occur, the Olympic bar 310 is rotated until the limiting post 421 abuts against the buckle post 410 to limit the rotation angle of the safety hook 420. The Olympic bar 310 is then safely hung on the buckle post 410 through the safety hook 420 to reduce the risk of being crushed.

[0039] Example 2: Refer to Figure 5 The difference between this embodiment and embodiment 1 is that a roller 351 is installed on the upper side of the horizontal plate of the fifth connecting plate 360 ​​of the lifting mechanism 300, and a guide rail groove 131 is opened on the lower side of the two short crossbeams above the support frame 100, and the roller 351 moves horizontally in the guide rail groove 131.

[0040] In other embodiments, the two snap-on posts 410 are respectively installed on the side of the two uprights 320 that are opposite to or close to each other, and the safety hook 420 and the limiting hook 430 both extend to the front side of the snap-on posts 410 and cooperate with the snap-on posts 410.

[0041] The implementation principle of Embodiment 2 of this utility model is as follows: When the Olympic rod 310 moves horizontally, the roller 351 moves horizontally together with the rectangular connecting plate 215 and the horizontal slider 214 in the guide rail groove 131. This can increase the stability of the horizontal moving device 200 during operation, share the lateral stress borne by the horizontal guide rail 221 during the movement of the horizontal slider 214, and improve the overall safety and stability. The safety hook 420 is set to L-shape. When the Olympic rod 310 needs to be suspended, the Olympic rod 310 can be rotated at a small angle to hang the safety hook 420 on the buckle column 410, shortening the distance between the column 320 and the buckle column 410, reducing the overall width of the training equipment, reducing the floor space, and saving space.

[0042] In summary, this design solves the problem of the fixed movement trajectory of traditional Smith machines, which does not conform to the natural movement trajectory of the human body. It allows the barbell to move freely, providing a training method closer to free weight, making the training movements more natural and conforming to the natural movement trajectory of the human body, thus reducing joint stress during training. The safety hook and limit hook provide dual safety protection. When fatigue occurs or problems arise, simply rotate the barbell slightly to safely hang it on the hook, preventing injury from being crushed.

[0043] While allowing for multi-directional movement, the track itself still provides some balance assistance, reducing the risk of injury due to loss of balance during heavy weight training. The starting position and angle of the Olympic bar can be easily adjusted to simulate various training movements, basically covering compound training of the major muscle groups of the whole body, saving space and improving the utilization rate of the equipment.

[0044] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
