Common indoor sport equipment has a lot, it includes treadmill, jack etc., it is by different frame for movement and the different flowing mode of doing, and produce different training effects, be available for users to take exercises the muscle group of diverse location, as biceps, chest muscle, arm flesh or the like, yet, be exclusively used on the market and train back and abdominal muscles group's sports equipment less simultaneously, although have, also, be difficult to carry and put, so produced the inconvenience of using often because of complex structure causes volume weight excessive.

Summary of the invention

The purpose of this utility model is to provide a Sit-Up Training Machine, and it is by simple frame for movement and make flowing mode, and is available for users to take exercise its dorsal abdominal muscle, and is not only easy to operate and volume weight is little, is easy to carrying and puts.

For reaching aforementioned purpose, Sit-Up Training Machine of the present utility model mainly includes:

One pedestal, its two ends form leg respectively, can be butted on the ground, make pedestal be able to stable ornaments on ground; Its contiguous wherein end place has been horizontally set with a fixed bar, and its middle section is provided with the articulated section, and in addition, the other end place end face of its relative fixed bar is provided with a seat;

One backrest bolster, it is the middle section that upright mode is inserted in pedestal, and the articulated section of its contiguous bottom part support body and pedestal is pivoted mutually, pivots and make the backrest bolster be able to relative pedestal; And a plurality of flexible members have been connected to each other between this backrest bolster bottom and the fixed bar.

During use, the user can take on seat, is resisted against the backrest bolster with the back, so, with the abdomen back of the body application of force backrest bolster is compressed backward again, makes the relative pedestal of backrest bolster pivot; In the process that the backrest bolster pivots, aforementioned flexible member can spur the bottom of backrest bolster, produce an opposing user opposing torque, allow the user need to such an extent that the lasting application of force is resisted this opposing torque and the backrest bolster can be depressed fully, thereby reach the purpose of training back and the different muscle groups of belly;

After the user depressed the backrest bolster fully, the opposing torque that aforementioned flexible member pulling backrest bolster bottom is produced can order about the backrest bolster and oppositely pivot toward original position, thus, and the user is provided an active force, help the user to reply its former sitting posture, and repeated aforementioned activities.

As from the foregoing, Sit-Up Training Machine of the present utility model, it makes flowing mode and mechanical realization is all comparatively simple, so not only easy to operate, and volume weight is little and be easy to carrying and put, so its use more convenient.

The specific embodiment

Please referring to Figure 1 and Figure 2, Sit-Up Training Machine of the present utility model includes a pedestal 10, a backrest bolster 20 and two arm-rest frames 30, wherein:

This pedestal 10 includes the seat bar 11 of two mutually parallel and bendings, and the end place of these two bars 11 forms leg respectively, can be butted on the ground, makes pedestal 10 be able to stable ornaments on ground; Be horizontally set with a fixed bar 12 between the body of rod of these two bars, 11 contiguous wherein ends, these fixed bar 12 spaced surfaces are provided with a plurality of hook parts 120; And these two bar 11 middle sections are provided with an articulated section 13, and in addition, the other end end face of its relative fixed bar 12 is provided with a seat 15, and seat 15 front bottom end have been horizontally set with a sleeve pipe 14;

This backrest bolster 20 is to be between the middle section that upright mode is inserted in a bar 11, include two hack levers 21, parallel interval is provided with a plurality of rollers 22 between this two hack lever 21, and these two hack levers, 21 contiguous bottom parts are pivoted mutually with the articulated section 13 of seat bar 11, pivot and make backrest bolster 20 be able to relative pedestal 10; In addition, be connected with one between these two hack levers, 21 bottoms and be subjected to bar 23 (please referring to shown in Figure 3), this is subjected to bar 23 parallel with fixed bar 12, and these a plurality of hook parts 120 are interval with a plurality of button hooks 230 relatively; Wherein, please cooperate referring to shown in Figure 3, between each relative hook part 120 and the button hook 230, be respectively arranged with a flexible member 24, this flexible member 24 can be spring, and the one end colludes on hook part 120, and the other end colludes on button hook 230;

These two arm-rest frames, 30 one ends are formed with joint portion 31 respectively, can overlap to be bonded to sleeve pipe 14 two ends and to combine with pedestal 10, the body of rod outside its joint portion 31 then relatively joint portion 31 vertically bend, formation is positioned at the handrail 32 of pedestal 10 both sides.

Please referring to shown in Figure 4, during use, the user can take on seat 15, be resisted against with the back on the roller 22 of backrest bolster 20, and optionally grip the handrail 32 that is positioned at pedestal 10 both sides with hand, so, with the abdomen back of the body application of force backrest bolster 20 is compressed again backward, make backrest bolster 20 relative pedestals 10 pivot; In the process that backrest bolster 20 pivots, aforementioned flexible member 24 can spur the bottom of backrest bolster 20, produce an opposing user opposing torque, allow the user need to such an extent that the lasting application of force is resisted this opposing torque and backrest bolster 20 can be depressed fully, thereby reach the purpose of training back and the different muscle groups of belly;

Please referring to Fig. 5 and shown in Figure 6, after the user depresses backrest bolster 20 fully, the opposing torque that aforementioned flexible member 24 pulling backrest bolsters 20 bottoms are produced, can order about backrest bolster 20 oppositely pivots toward original position, thereby an active force that helps user's upper body to lift is provided, so, the user can optionally hold handrail 32 with hand again, can reply former sitting posture easily, repeat aforementioned activities.
