Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a back stretcher. Background Technology

[0002] The back stretcher is a device used to assist users in stretching their back. However, existing back stretchers usually use a fixed arc frame for users to stretch while lying down. When using it, users need to do sit-ups repeatedly to achieve the stretching effect, resulting in a poor user experience and less than ideal stretching effect.

[0003] In view of this, the inventor of this utility model conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Utility Model Content

[0004] The purpose of this invention is to address the above shortcomings by providing a back stretcher that is simple in structure, easy to use, small in size, and has a good stretching effect.

[0005] The solution adopted by this utility model to solve the technical problem is: a back stretcher, including a back plate, the front of the back plate is provided with a backrest, the backrest is provided with an upwardly protruding arc-shaped protrusion for stretching the human back, and the back of the back plate is provided with a downwardly protruding arc-shaped support, so as to change the center of gravity position of the back plate by rolling the arc-shaped support, thereby stretching and massaging different positions of the back.

[0006] Furthermore, in order to form a support platform for the upper body, the arc-shaped protrusion is located in the middle of the backrest. The backrest is also provided with a lower platform below the arc-shaped protrusion for supporting the buttocks and an upper platform above the arc-shaped protrusion for supporting the shoulders. The length of the arc-shaped protrusion is greater than the length of the upper and lower platforms to ensure that the arc-shaped protrusion covers the entire back of the human body.

[0007] Furthermore, in order to ensure that the backrest covers the entire upper body of the human body and fully stretches all parts of the lower back, the length of the backrest is 0.35m-0.5m to support the upper body, the length of the arc-shaped protrusion is 0.2-0.3m, and the radius of the arc-shaped protrusion is 0.15m-0.25m to adapt to the contour of the human back.

[0008] Furthermore, in order to make the back panel swing on the ground to stretch and massage different parts of the user's waist and back, and to improve the structural strength of the arc-shaped support, the arc-shaped support includes two arc-shaped rods, which are respectively located on both sides of the back panel, and a connecting rod is provided between the two arc-shaped rods to improve the structural strength of the arc-shaped support.

[0009] Furthermore, in order to expand the swing angle of the back plate and ensure that the center of gravity of the tensioner is downward, the arc-shaped rod has a semi-circular structure to ensure 180-degree rotation of the back plate. The diameter of the arc-shaped rod is smaller than the length of the back plate. The arc-shaped rod includes an upper connecting end connected to the upper side of the back plate and a lower connecting end connected to the lower end face of the back plate, and the upper connecting end is located above the arc-shaped protrusion.

[0010] Furthermore, to ensure the user lies stably on the stretcher and prevents the user from falling off, thus providing safety during use, a handrail assembly is provided on the lower side of the back panel. The handrail assembly includes two symmetrically arranged handrails. Each handrail includes a support section for cooperating with the arc-shaped bracket to place the stretcher flat on the ground, and a handrail section extending upward at an angle from the support section. A seat plate for mounting the handrails is provided on the lower side of the back panel, and the two handrails are fixedly mounted on the seat plate by bolts and nuts.

[0011] Furthermore, to prevent the user's head from hitting the ground during the backrest rotation and lumbar support stretching process, and to adjust the height of the headrest assembly according to different users, the upper side of the backrest is equipped with a headrest assembly, which includes a mounting rod and a headrest. The lower end of the mounting rod is retractably mounted on the backrest, and the headrest is mounted on the upper end of the mounting rod. The upper side of the backrest is equipped with a telescopic sleeve rod, and the lower end of the mounting rod is retractably mounted inside the telescopic sleeve rod. The telescopic sleeve rod is equipped with a locking screw for locking the mounting rod inside the telescopic sleeve rod, and the mounting rod has several locking holes along the telescopic direction for inserting the locking screw.

[0012] Furthermore, to prevent the mounting rod from deforming due to frequent contact with the ground, the mounting rod includes a telescopic section that is pulled and connected to the telescopic sleeve rod and a ground contact section for contacting the ground. Several locking holes are provided in the telescopic section. The ground contact section extends obliquely upward from the upper end of the telescopic end to ensure that the ground contact section is flush with the ground when the arc-shaped bracket rotates to its maximum angle.

[0013] Furthermore, to facilitate the use of the lumbar and back stretcher, the lumbar and back stretcher also includes a seat cushion that is movably placed in front of the lower side of the back panel, and the seat cushion is filled with sponge.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] (1) This utility model has a simple structure and is easy to use. The overall size of the device is small and the area occupied is small. Compared with the existing complex and bulky stretchers, the simple structure of this utility model is more practical. Specifically, the arc-shaped protrusion fits the contour of the human waist and back, which can achieve a better stretching effect. The setting of the hand support component and the headrest component effectively ensures the safety and comfort during use.

[0016] (2) Existing stretchers are usually fixed arc-shaped frame structures. When stretching, users stretch their waist and back by lying on the arc-shaped frame. After completing one stretch, they need to sit up and lie down again to perform a second stretch. However, this utility model is different from the stretching method of existing stretchers. When stretching, users can lie on the stretcher continuously without sitting up. When stretching, the back plate is driven to swing back and forth along the arc-shaped frame by exerting force through the feet and back to change its center of gravity position, thereby achieving the purpose of stretching and massaging different parts of the waist and back, which can provide users with a better user experience.

[0030] In this embodiment, in order to expand the swing angle of the back plate 1 and ensure that the center of gravity of the tensioner is downward, the arc rod 301 has a semi-circular structure to ensure that the back plate 1 can rotate 180 degrees. The diameter of the arc rod 301 is smaller than the length of the back plate 1. The arc rod 301 includes an upper connecting end connected to the upper side of the back plate 1 and a lower connecting end connected to the lower end face of the back plate 1, and the upper connecting end is located above the arc protrusion 201.

[0031] In this embodiment, to ensure the user lies stably on the stretcher and to prevent the user from falling off, thus providing safety during use, a handrail assembly is provided on the lower side of the back plate 1. The handrail assembly includes two symmetrically arranged handrails 4. Each handrail 4 includes a support section 401 for cooperating with the arc-shaped bracket 3 to place the stretcher flat on the ground, and a handrail section 402 extending obliquely upward from the support section 401. The angle between the support section 401 and the handrail section 402 is 90 degrees. A seat plate 102 for mounting the handrails 4 is provided on the lower side of the back plate 1. The two handrails 4 are fixedly mounted on the seat plate 102 by bolts and nuts.

[0032] In this embodiment, to prevent the user's head from hitting the ground during the rotation and stretching of the backrest 1, and to adjust the height of the headrest assembly according to different users, the backrest 1 is provided with a headrest assembly on its upper side. The headrest assembly includes a mounting rod 6 and a headrest 7. The lower end of the mounting rod 6 is retractably mounted on the backrest 1, and the headrest 7 is mounted on the upper end of the mounting rod 6.

[0035] The method for using a back stretcher includes the following steps:

[0036] (1) Before using the back stretcher, the user places the seat cushion 5 in front of the back panel 1, sits on the seat cushion 5, holds the handrail 4 with both hands, and presses the back against the backrest 2.

[0037] (2) Then, the user exerts force through the waist and legs to drive the back panel 1 to roll back and forth along the arc-shaped support 3, thereby changing the contact point between the user's waist and back and the backrest 2, so as to change the position of waist and back stretching.

[0038] This utility model has a simple structure and is easy to use. The overall size of the device is small and it occupies little space. Compared with the existing complex and bulky stretchers, the simple structure of this utility model is more practical. Specifically, the arc-shaped protrusion 201 fits the contour of the human waist and back, which can achieve a better stretching effect. The setting of the hand support component and the headrest component effectively ensures the safety and comfort during use.

[0039] Existing stretching devices typically have a fixed arc-shaped frame structure. When stretching, users lie on the arc-shaped frame to stretch their lower back. After completing one stretch, they need to sit up and lie down again to perform a second stretch. However, this utility model differs from the stretching method of existing stretching devices. During stretching, users can lie continuously on the stretching device without sitting up. When stretching, the back plate 1 is driven to swing back and forth along the arc-shaped support 3 by exerting force through the legs and back, thereby changing its center of gravity position and achieving the purpose of stretching and massaging different parts of the lower back, providing users with a better user experience.
