Description

Technical Field

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

[0002] Existing back stretchers are generally either elastic rope type or shape stick type. Elastic rope type back stretchers require the user to grasp both ends of the elastic rope and pull it outward to stretch the back. Shape stick type back stretchers typically use a cross-shaped shape stick. The shape stick is placed against the back, and the user extends their arms backward to clamp the ends of the horizontal bar of the shape stick. The vertical bar rests against the back, and the arms clamp the horizontal bar to apply pressure to the back, thus stretching the back. Both elastic rope type and shape stick type back stretchers require the user to apply force to achieve the effect of stretching the back. They cannot stretch the back automatically, which is inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a pneumatic back opener that overcomes the above-mentioned defects and can automatically open the back of the human body.

[0004] To achieve the above objectives, the solution of this utility model is as follows: A pneumatic back opener includes a main body that can be placed behind the neck, back, and waist of a person. The main body has detachable crossbars on its left and right sides. When the main body is behind the neck or waist, the crossbars can be gripped by the hands to keep the main body in place behind these areas. When the main body is behind the back, the crossbars can be wrapped around the back of the body with the arms, resting against the arm joints to keep the main body in place behind the back. An air bag is located at the front of the main body; the air bag can inflate and push forward to press the neck, back, and waist forward, and the arms exert a backward reaction force on the shoulders and back to open the back. Furthermore, the airbag is divided into two layers, front and back, which are connected to each other to inflate and deflate together.

[0005] Furthermore, the rear part of the airbag is composed of a single first airbag, which is fixed to the front of the main body. The front part of the airbag is composed of two independent second airbags, which are spaced apart on the first airbag and connected to the first airbag respectively. When the airbag is inflated, the two second airbags come into contact with the human body and simultaneously press against the neck, back and waist of the human body, and jointly support the main body to prevent the main body from tilting up and down.

[0006] Furthermore, the crossbar is screwed onto the main body to allow for disassembly and assembly.

[0007] Furthermore, a threaded post is provided at one end of the crossbar near the main body, and through holes are provided on the left and right sides of the main body. The inner wall of the through holes is provided with threaded sections, and the threaded post can be screwed into the through holes, thereby screwing the crossbar onto the main body.

[0008] Furthermore, the air bag is connected to an inflation / deflation component, which can inflate and deflate the air bag.

[0009] Furthermore, the inflation / deflation component is located inside the main body. The inflation / deflation component includes a control circuit board, a rechargeable battery, an air pump, an air valve, and an air pipe. The air pump and air valve control the inflation and deflation of the air bag. The air pump and air valve are connected to the air bag through the air pipe. The control circuit board is electrically connected to the rechargeable battery and is also electrically connected to the air pump and air valve.

[0010] Furthermore, it also includes a protective sleeve, which is fitted over the main body and the air bag. A crossbar passes through the protective sleeve and is detachably connected to the main body. The protective sleeve is made of elastic fabric material in at least the area corresponding to the air bag to accommodate the deformation of the air bag, while in other areas it is made of rigid material by hot pressing and corresponds to the shape of the main body.

[0011] After adopting the above solution, the beneficial effects of this utility model are as follows: The main body of this pneumatic back opener can be placed behind the neck, back, and waist. When placed behind the neck or waist, the user holds the crossbar with their hands, keeping the main body behind the neck and shoulders. Then, the air bag inflates and pushes forward, pushing the neck and waist forward. The arms then apply a backward reaction force to the shoulders and back, thus opening the back. When placed behind the back, the user wraps their arms around the crossbar, allowing the crossbar to rest against their arms, keeping the main body behind the back. The air bag inflates and pushes forward, pushing the back forward. The arms then apply a backward reaction force to the shoulders and back, thus opening the back. Therefore, this invention can automatically open the back, which is quite convenient. The crossbars of this utility model are detachably set on the left and right sides of the main body. When packaging the pneumatic back opener, the crossbars can be removed and stacked on top of or below the main body, reducing the space occupied by the pneumatic back opener, thereby reducing the packaging volume of the pneumatic back opener, reducing the material cost of packaging, and also saving transportation costs. This invention uses an inflatable airbag to press against the neck, waist, and back of the human body, increasing the contact area with the body, avoiding localized pressure and pain, and allowing for pressure application to the corresponding areas of the airbag, thus optimizing the user experience.

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 5 As shown, this embodiment provides a pneumatic back opener, including a main body 10. The main body 10 can be placed on the back of the neck, back, and waist of a person. A crossbar 20 is detachably provided on the left and right sides of the main body 10. When the main body 10 is on the back of the neck and waist, the crossbar 20 can be held by the person's hands to keep the main body 10 on the back of the neck and waist. When the main body 10 is on the back of the person, the crossbar 20 can be wrapped around the back of the person with the arms, so that the crossbar 20 rests against the arm joint to keep the main body 10 on the back of the person. An air bag 30 is provided on the front of the main body 10. The air bag 30 can be inflated and pushed forward to push the neck, back, and waist forward, and the arms will cause the shoulders and back to receive a backward reaction force to open the back.

[0016] Specifically, the main body 10 is made of rigid material and has a cavity inside. The front side of the main body 10 is the side facing the human body when the main body 10 is placed behind the human body, the back side of the main body 10 is the side away from the human body, and the left and right sides of the main body 10 correspond to the left and right sides of the human body's left and right hands.

[0017] It is understood that the pneumatic back opener of this utility model can be disassembled from the main body 10 when the human body is lying flat, and then the main body 10 can be placed under the human body's waist, so that the air bag 30 can lift, press and massage the waist. Furthermore, the airbag 30 is divided into front and rear layers. The front layer and the rear layer of the airbag 30 are interconnected to inflate and deflate together. Preferably, the rear layer of the airbag 30 is composed of a single first airbag 31, which is fixed to the front of the main body 10. The front layer of the airbag 30 is composed of two independent second airbags 32, which are spaced apart vertically on the first airbag 31 and are connected to the first airbag 31 respectively. When the airbag 30 is inflated, the two second airbags 32 come into contact with the human body and simultaneously press against the neck, back, and waist of the human body, and jointly support the main body 10 to prevent the main body 10 from tilting vertically.

[0018] Preferably, the crossbar 20 is screwed onto the main body 10 so that it can be disassembled and assembled; specifically, a threaded post 21 is provided at one end of the crossbar 20 near the main body 10, and through holes 11 are provided on the left and right sides of the main body 10. The inner wall of the through hole 11 is provided with a threaded section, and the threaded post 21 can be screwed into the through hole 11, thereby screwing the crossbar 20 onto the main body 10.

[0019] Furthermore, the air bag 30 is connected to an inflation / deflation component 40, which can inflate and deflate the air bag 30. Specifically, the inflation / deflation component 40 is located in the cavity of the main body 10. Preferably, the inflation / deflation component 40 includes a control circuit board 41, a rechargeable battery 42, an air pump 43, an air valve 44, and an air pipe (not shown in the figure). The air pump 43 and the air valve 44 control the inflation and deflation of the air bag 30. The air pump 43 and the air valve 44 are connected to the air bag 30 through the air pipe. The control circuit board 41 is connected to the rechargeable battery 42 and is also electrically connected to the air pump 43 and the air valve 44 to control the start and stop of the air pump 43 and the air valve 44.

[0020] Furthermore, it also includes a protective sleeve 50, which is fitted over the main body 10 and the air bag 30. The crossbar 20 passes through the protective sleeve 50 and is detachably connected to the main body 10. The protective sleeve 50 is used to protect the main body 10 and the air bag 30 from damage. The protective sleeve 50 is made of elastic cloth material in at least the area corresponding to the air bag 30 so as to adapt to the deformation of the air bag 30. In other areas, it is made of rigid material by hot pressing and corresponds to the shape of the body.

[0021] Specifically, a button 60 is also provided on the main body 10. The button 60 is linked to the control circuit board 41. By pressing the button 60, the air pump 43 can be turned on and off. The inflation and deflation of the air bag 30 can also be controlled by pressing the button 60, thereby controlling the opening mode, such as gradually accelerating or slowing down the inflation of the air bag 30.
