Description

Technical Field

[0001] The present invention relates to the field of Smith technology, in particular to a multi-angle Smith. Background Art

[0002] The Smith machine is a common piece of fitness equipment, consisting of a frame and a barbell that slides onto it. Because the barbell's sliding path is restricted by the frame, trainees can confidently use heavy weights. Furthermore, it's not limited to squats; it can also be used for bench presses, biceps curls, heel raises, and more.

[0003] The Smith machine in the prior art has weight guide rods arranged vertically and in parallel, and the weights on the weight guide rods can only move vertically upward and downward, resulting in that the motion trajectory cannot be changed. It cannot adapt to different movement training requirements and cannot meet the requirements of athletes to perform more training movements. Due to the different joint mobility of each trainee, for example, during squats, due to limited hip joint mobility, a more inclined trajectory is required to reduce lumbar spine pressure, but the fixed track of the traditional Smith machine cannot be adjusted, which may cause movement deformation or joint discomfort for some trainees. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a multi-angle Smith.

[0005] The technical solution is as follows: A multi-angle Smith comprises a frame body, both sides of which are rotatably connected to adjustment frames, and a first limit assembly is connected to the frame body between the two adjustment frames; The first limiting assembly includes two mounting plates arranged on the inner wall of the frame and rollers arranged on the top of both sides of the adjustment frame. A guide portion for the rollers to roll is formed on the top wall of the mounting plates, and the two mounting plates are arranged vertically symmetrically along the frame.

[0006] Furthermore, one end of the top of the inner wall of the adjustment frame is rotatably connected to a vertically arranged guide assembly, a sliding matching assembly is slidably installed on the guide assembly, a mounting block is fixedly connected to the bottom of the guide assembly, and a guide plate is fixedly connected to the bottom of the end of the adjustment frame away from the roller 540, a guide groove for the mounting block to slide is formed on the side wall of the guide plate, and a second limit assembly is connected to the mounting block.

[0007] Furthermore, a plurality of through holes are formed on the side wall of the mounting plate, and a plug hole corresponding to the plurality of through holes is formed on the side wall of the adjustment frame. Pins for plugging into the plug hole are detachably installed in the through holes.

[0008] Furthermore, the guide assembly includes a fixed block, two counterweight guide rods and a hanging rod are fixedly connected to the bottom wall of the fixed block, the hanging rod is arranged between the two counterweight guide rods, the sliding counterweight group includes a sliding block slidably arranged on the two counterweight guide rods, the sliding block is fixedly connected to a handle portion and a counterweight portion vertically arranged along the length direction of the adjustment frame, the handle portion is arranged inside the adjustment frame, and the counterweight portion is arranged outside the frame body; A plurality of weight hanging parts arranged parallel to the handle part are connected to the side wall of the hanging rod, and a hook matched with the weight hanging part is fixedly connected to the handle part.

[0009] Furthermore, a plurality of positioning holes are opened and connected on the side wall of the guide plate, and mounting holes corresponding to the positioning holes are opened and connected on the side wall of the mounting block. The second limiting assembly includes an insertion rod slidably arranged in the mounting hole, and a spring is connected between the mounting block and the insertion rod. The spring is used to maintain the elastic force that presses the insertion rod toward the positioning hole.

[0010] Furthermore, a connecting rod is detachably installed between adjacent sliding counterweight groups, a plug-in cavity is opened at the end of the handle, both ends of the connecting rod have a plug-in portion that is plugged into the plug-in cavity, the outer wall of the handle end has an external thread, and sleeves that cooperate with the external thread are rotatably installed on the outer walls of both ends of the connecting rod.

[0011] Furthermore, an anti-slip sleeve is connected to the outer wall of the handle.

[0012] From the above, the beneficial effects of a multi-angle Smith in the present invention are as follows: When it is necessary to adjust the inward inclination angle of the adjustment frame, the pins in the through holes at both ends of the frame are pulled out, and then the adjustment frame is adjusted to the required angle. The pins are inserted into the through holes and plugged into the corresponding sockets to complete the angle adjustment of the adjustment frame. Through the setting of the rotatable adjustment frame and the first limit assembly, the inclination angles of the adjustment frames on both sides can be adjusted as a whole. The movement trajectory of the sliding counterweight group is no longer limited to the vertical direction, and can be adjusted to a left-leaning or right-leaning inclination path, which expands the functionality of the Smith machine and facilitates adaptation to different movement training requirements.

[0013] When it is necessary to perform exercises at an inclined angle, the rod is pulled out of the positioning hole. At this time, the spring is in a compressed state, pushing the guide assembly to adjust the angle of the guide assembly. After the adjustment is completed, the rod is loosened and the spring releases the pressure. The rod can be pushed into the corresponding positioning hole after adjustment to position the mounting block, that is, the guide assembly. It can be adjusted to a forward inclined path, meeting the athlete's requirements for more training movements.

[0014] The connecting rods can be disassembled and assembled according to the needs of exercise. When the connecting rods are not installed, the sliding counterweight group can be used for separate single-handed exercise. When the connecting rods are installed, conventional exercises such as bench presses or squats can be performed, realizing the functions of a traditional straight-bar Smith machine.

[0015] Through the coordinated setting of the adjustable adjustment frame and the guide assembly, it can be adjusted in multiple directions at the same time, realizing the conversion of multi-directional motion trajectories, meeting the requirements of athletes for more training movements, greatly expanding the diversity of training movements, and accurately adapting to the individual joint mobility and body structure of different trainees (especially solving the problem of lumbar spine pressure during squats), thereby improving training comfort, movement efficiency and safety.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] The embodiments provided by the present invention will be described in detail below: like Figures 1 to 5 As shown, it includes a frame body 100, with adjustment frames 110 rotatably connected to both sides of the frame body 100, and a first limiting component is connected between the two adjustment frames 110; The first limiting component includes two mounting plates 510 arranged on the inner wall of the frame 100 and rollers 540 arranged on the top of both sides of the adjustment frame 110. A guide portion 530 for the rollers 540 to roll is formed on the top wall of the mounting plates 510. The two mounting plates 510 are arranged vertically symmetrically along the frame 100.

[0020] A fixing frame is connected between the two mounting plates 510, and a pull-up bar for exercise is provided below the fixing frame. At the same time, the fixing frame is located at the end of the guide portion 530 of the two mounting plates 510. When the adjustment frame 110 is rotated inward to the maximum limit, the fixing frame can support the adjustment frame 110.

[0021] It is understandable that by providing a pull-up bar, the training methods can be increased and the practicality and applicability of the device can be improved.

[0022] It should be noted that the guide portion 530 is arranged in an arc shape, and the radius of the guide portion 530 is the same as the distance from the lower end surface of the roller 540 to the rotation axis of the adjustment frame 110, ensuring that the adjustment frame 110 is subjected to balanced force during the rotation angle adjustment process, and avoiding jamming or twisting deformation caused by the force on the roller 540.

[0023] In addition, the roller 540 rolls within the guide portion 530, converting the sliding friction of the adjustment frame 110 into rolling friction, significantly reducing the adjustment resistance. When adjusting, one only needs to release the latch 550 that locks the adjustment frame 110, and then easily push the adjustment frame 110 by hand to change the angle without the need for additional tools or forceful operation.

[0024] It should be noted that the setting of the first limit assembly ensures that the angles of the adjustment frame 110 and the guide assembly can be firmly locked after setting, preventing accidental movement or shaking during training and ensuring the stability and safety of the training process.

[0025] like Figure 5As shown, a plurality of through holes 520 are formed on the side wall of the mounting plate 510 , and a plug hole 610 corresponding to the plurality of through holes 520 is formed on the side wall of the adjustment frame 110 . A pin 550 for plugging into the plug hole 610 is detachably installed in the through hole 520 .

[0026] It should be noted that the plurality of through holes 520 are arranged in an arc shape and are located on the rotation track of the adjustment frame 110 , thereby enabling the adjustment frame 110 to be adjusted to different tilt angles as required.

[0027] Specifically, when it is necessary to adjust the inward inclination angle of the adjustment frame 110, the pins 550 in the through holes 520 at both ends of the frame 100 are pulled out, and then the adjustment frame 110 is adjusted to the required angle. The pins 550 are inserted into the through holes 520 and plugged into the corresponding sockets 610 to complete the angle adjustment of the adjustment frame 110. Through the setting of the rotatable adjustment frame 110 and the first limit assembly, the inclination angles of the adjustment frames 110 on both sides can be adjusted as a whole. The relative rotation directions of the sliding counterweight group 220 are no longer limited to the vertical direction, and can be adjusted to a left-leaning or right-leaning inclination path, thereby expanding the functionality of the Smith machine and facilitating adaptation to different movement training requirements.

[0028] The adjustment frames 110 on both sides can be adjusted individually or synchronously. When performing single-handed training, unilateral adjustment can be performed. When performing double-handed training, the angle can be adjusted synchronously.

[0029] like Figure 6 As shown, guide assemblies are vertically provided at one end of the top of both sides of the inner wall of the adjustment frame 110, a sliding counterweight group 220 is slidably installed on the guide assembly, a mounting block 660 is fixedly connected to the bottom of the guide assembly, and a guide plate 230 is fixedly connected to the bottom of the end of the adjustment frame 110 away from the roller 540, and a guide groove 650 for sliding the mounting block 660 is formed on the side wall of the guide plate 230, and a second limit assembly is provided on the mounting block 660.

[0030] The guide assembly includes a fixed block 620, two counterweight guide rods 210 and a hanging rod 630 are fixedly connected at the bottom wall of the fixed block 620, the hanging rod 630 is arranged between the two counterweight guide rods 210, the sliding counterweight group 220 is slidably arranged on the two counterweight guide rods 210, and the sliding counterweight group 220 includes a sliding block 930 slidably arranged on the two counterweight guide rods 210, and the sliding block 930 is fixedly connected to a handle portion 940 and a counterweight portion 950 vertically arranged along the length direction of the adjustment frame 110, the handle portion 940 is located inside the adjustment frame 110, and the counterweight portion 950 is located outside the frame body 100; It should be noted that the handle portion 940 is rotatably mounted on the sliding block 930, the weight portion 950 is fixedly connected to the sliding block 930, and weight plates are detachably mounted on the weight portion 950 by bolts. The trainee can install different numbers of weight plates as needed to suit their needs.

[0031] Among them, a barbell lock is installed on the counterweight part 950, which is a prior art and will not be described in detail here.

[0032] In addition, the sliding block 930 is arranged on the outside of the frame 100, and a sleeve is fixedly connected to the corresponding side of the sliding block 930 and the counterweight guide rod 210. The sleeve is slidably arranged on the two counterweight guide rods 210. Through the setting of the double counterweight guide rod 210, the jamming or shaking caused by the deformation of the counterweight guide rod 210 under heavy weight is avoided.

[0033] like Figure 6 and Figure 9 As shown, a plurality of weight hanging parts 640 arranged parallel to the handle part 940 are connected to the side wall of the hanging rod 630, and a hook 960 cooperating with the weight hanging part 640 is fixedly connected to the handle part 940.

[0034] The plurality of weight hanging parts 640 are fixedly connected to the hanging rod 630 at equal intervals.

[0035] Specifically, during training, the trainee holds the handle portion 940 and rotates it outward so that the hook 960 is detached from the weight hanging portion 640. At this time, the trainee can perform push-up training. After the training is completed, the handle portion 940 is rotated inward so that the hook 960 is hung on the nearest weight hanging portion 640.

[0036] like Figures 6 to 8 As shown, a plurality of positioning holes are provided on the side wall of the guide plate 230, and a mounting hole corresponding to the positioning hole is provided on the side wall of the mounting block 660. The second limiting assembly includes an insertion rod 810 slidably arranged in the mounting hole, and a spring 820 is connected between the mounting block 660 and the insertion rod 810. The spring 820 is used to maintain the elastic force that presses the insertion rod 810 toward the positioning hole.

[0037] Among them, the multiple positioning holes are arranged in an arc shape and are located on the rotation track of the installation block 660. That is, when the guide component rotates along the rotation axis, it drives the installation block 660 to rotate in an arc track.

[0038] Specifically, when it is necessary to perform an exercise at an inclined angle, the rod 810 is pulled out of the positioning hole. At this time, the spring 820 is in a stretched state, pushing the guide assembly to adjust the angle of the guide assembly. After the adjustment is completed, the rod 810 is loosened, and the spring 820 releases the pressure, and the rod 810 can be pushed into the corresponding positioning hole after adjustment to position the mounting block 660, that is, the guide assembly.

[0039] like Figure 9 As shown, connecting rods 240 are detachably installed between adjacent sliding counterweight groups 220 by bolts, a plug-in cavity is opened at the end of the handle portion 940, both ends of the connecting rod 240 have a plug-in portion 910 inserted into the plug-in cavity, the outer wall of the end of the handle portion 940 has an external thread, and sleeves 920 that cooperate with the external thread are rotatably installed on the outer walls of both ends of the connecting rod 240.

[0040] It should be noted that an internal thread that cooperates with the external thread is formed on the inner wall of the sleeve 920, so that it is used to strengthen the connection with the handle part 940 when the connecting rod 240 is installed. When disassembly is required, the sleeve 920 can be separated from the handle part 940 by rotating it, and then the plug-in part 910 can be pulled out of the plug-in cavity for disassembly. The operation is simple and the connection is stable and reliable.

[0041] The outer wall of the connecting rod 240 is also connected to an anti-slip sleeve.

[0042] Specifically, the connecting rod 240 can be disassembled and assembled according to the needs of exercise. When the connecting rod 240 is not installed, the sliding counterweight group 220 can be used for independent single-handed exercise. When the connecting rod 240 is installed, conventional exercises such as bench press or squats can be performed, realizing the function of a traditional straight-bar Smith machine.

[0043] An anti-slip cover is connected to the outer wall of the handle portion 940 to facilitate the user to perform hand grip exercises.

[0044] Specifically, when the Smith machine needs to be used normally, the function of a traditional straight-bar Smith machine can be realized by installing the connecting rod 240 between the two sliding counterweight groups 220; after removing the middle connecting rod 240, single-handed exercise or left-right hand alternating push-up training can be performed. When the adjustment frame 110, that is, the guide assembly, needs to be adjusted inward to a suitable angle, it can be seen in FIG. Figure 4 and Figure 5 , forming a state of being wider at the bottom and narrower at the top, thereby changing the angle of the movement trajectory along the upper and lower vertical directions; When it is necessary to perform an inclination angle exercise, the rod 810 is pulled out of the positioning hole. At this time, the spring 820 is in a stretched state, pushing the guide assembly to adjust the angle of the guide assembly. After the adjustment is completed, the rod 810 is loosened, and the spring 820 releases the pressure, and the rod 810 can be pushed into the corresponding positioning hole after adjustment to position the mounting block 660, that is, the guide assembly. The movement direction can be adjusted in multiple directions at the same time, realizing the conversion of multi-directional movement trajectories, meeting the requirements of athletes for more training movements, greatly expanding the diversity of training movements, accurately adapting to the individual joint mobility and body structure of different trainees (especially solving the lumbar pressure problem during squats), and improving training comfort, movement efficiency and safety.

[0045] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on one or several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the scope of protection of the present application.

[0046] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The embodiments shown in the embodiments are only part of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the above and, without departing from the purpose of the present invention, designs a structure and embodiment similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
