Description
技术领域 technical field
本发明属于日常体育用品设备领域，具体涉及一种仰卧起坐健身器。 The invention belongs to the field of daily sporting goods equipment, and in particular relates to a sit-up fitness machine.
背景技术 Background technique
仰卧起坐，一种锻炼身体的方式。仰卧，两腿并拢，两手上举，利用腹肌收缩，两臂向前摆动，迅速成坐姿，上体继续前屈，两手触脚面，低头；然后还原成坐姿。如此连续进行。做仰卧起坐运动的好处有：增加腹部肌肉的力量，锻炼较深层的肌肉，是锻炼腹肌的最有效方法之一；有利于肠胃运动，预防便秘的发生；减肚和收腹，拉伸腹部的肌肉，锻炼平衡感和协调性，并能提升免疫力。日常做仰卧起坐运动，需要有人按腿协助完成，增加了运动的局限性。仰卧起坐健身器可以有效的解决这个问题，可以使你随时随地进行仰卧起坐锻炼。 Sit-ups, a way to exercise your body. Lie on your back, keep your legs together, lift your hands up, use your abdominal muscles to contract, swing your arms forward, quickly get into a sitting position, continue to bend your upper body forward, touch your feet with your hands, and bow your head; then return to a sitting position. And so on. The benefits of doing sit-ups include: increasing the strength of abdominal muscles and exercising deeper muscles, which is one of the most effective ways to exercise abdominal muscles; it is beneficial to gastrointestinal exercise and prevents constipation; reducing and tightening the abdomen, stretching Abdominal muscles, exercise balance and coordination, and improve immunity. Doing sit-ups every day requires someone to assist with pressing the legs, which increases the limitation of exercise. The sit-up fitness machine can effectively solve this problem, and can enable you to perform sit-up exercises anytime and anywhere.
现有的仰卧起坐健身器主要有平直固定式的，公园、小区的公共场所都有，虽然可以实现锻炼身体的目的，但受场地限制，一定要到室外有健身器的地方，仰卧角度不能进行调整，不适应不同腹部肥胖健身者的需要，同时平直固定式仰卧起坐健身器锻炼时对腰椎受力过大，健身者很累，对腰椎也无好处，甚至会引起腰椎受伤腰椎；同时，现有的仰卧起坐健身器仅仅只有健身作用，而没有对锻炼效果进行统计功能。 Existing sit-ups and sit-ups fitness machines mainly include flat and fixed ones, which are available in public places in parks and communities. It cannot be adjusted, and it does not adapt to the needs of different abdominal obese bodybuilders. At the same time, the flat and fixed sit-up fitness machine exerts too much force on the lumbar spine when exercising. The bodybuilder is very tired, which is not good for the lumbar spine, and may even cause lumbar spine injury. ; Simultaneously, existing sit-ups fitness equipment only has body-building effect, and does not carry out statistical function to exercise effect.
目前，已出现一些技术，在一定程度上解决了上述健身器高度调节的技术问题，例如专利申请号为：201220537755.1的发明专利《一种仰卧起坐健身器》，该健身器重点改进了仰卧板的外形设计，并对后支撑架增加了有定位孔的转盘，使得后支撑架高度可调；但是在调节后支撑架高度时需要终止锻炼，需要人手动调节，具体操作起来并不方便；同时，该健身器仅仅只能针对后支撑架的高度进行调节，而不能针对前支撑架的高度进行调节，也在一定程度上限制了该健身器的实用范围。 At present, some technologies have appeared to solve the technical problems of the height adjustment of the above-mentioned fitness equipment to a certain extent. For example, the patent application number is: 201220537755.1 "a sit-up fitness equipment", which focuses on improving the sit-up board The shape design, and a turntable with positioning holes is added to the rear support frame, so that the height of the rear support frame can be adjusted; however, when adjusting the height of the rear support frame, the exercise needs to be terminated, and manual adjustment is required, which is inconvenient to operate; at the same time , this fitness device can only be regulated for the height of rear support frame, but can not be regulated for the height of front support frame, has also limited the practical scope of this fitness device to a certain extent.
目前，也出现一些技术，在一定程度上解决了上述健身器锻炼效果统计的技术问题，例如专利申请号为：201220757180.4的发明专利《自动计数的仰卧起坐用垫》，该专利对仰卧起坐用垫做了改进，在垫体内夹装了压力传感器和计时\计数器，使得仰卧起坐用垫增加了对使用者所做运动的计时和计数功能。但是该专利仅仅解决了锻炼计数统计的问题，而没有进一步地对仰卧起坐健身器进行多功能化，从而使锻炼者在愉悦的环境中进行身体锻炼。 At present, there are also some technologies that have solved the technical problems of the exercise effect statistics of the above-mentioned fitness equipment to a certain extent. For example, the patent application number is: 201220757180.4's invention patent "Mat for sit-ups with automatic counting". The pad is improved, and a pressure sensor and a timing/counter are clamped in the pad body, so that the pad for sit-ups increases the timing and counting functions of the exercise done by the user. But this patent only solves the problem of exercise counting and statistics, and does not carry out multi-functionalization to sit-up fitness machine further, thereby makes exerciser carry out physical exercise in pleasant environment.
所以，市场上迫切需要一种既能调节前、后支撑架高度，又能计数统计锻炼效果，并且还能播放音乐、视频等娱乐节目的仰卧起坐健身器。 Therefore, there is an urgent need in the market for a sit-up fitness machine that can both adjust the height of the front and rear support frames, count and count the exercise effects, and can also play entertainment programs such as music and videos.
