Summary of the invention
The purpose of this invention is to provide a kind of strong abdomen chair of lying on the back, it is longer service life that it has elastic force apparatus, and the characteristics of working stability.After the optimization, it has the advantages that function is more, can differentiated be applicable to the person taking exercise of different heights.
The technical solution adopted in the present invention is: the strong abdomen chair of lying on the back, comprise the side arm and the after-frame that link together, wherein, this side arm top is provided with support bar, the middle part is provided with the pin raker, this after-frame front portion is provided with cushion, the middle part is hinged with rod, this rod is provided with back cushion, the rear side of described rod is hinged with spring mechanism by " U " shape seat of going up that is fixed on this rod, following " U " shape seat at the rear portion of the other end of this spring mechanism by being fixed on this after-frame is hinged on this after-frame, and this spring mechanism sleeve pipe of comprising spring and being enclosed within this spring outside.
The below that is positioned at this cushion on the described after-frame is provided with handrail.
Described side arm comprise the cover be plugged together put on the shelf and undercarriage, and this put on the shelf and undercarriage between be provided with the bolt-type height adjustment mechanism.
Described pin raker is fixed in pin and colludes on the adjustable pipe, and this pin colludes adjustable pipe and is enclosed within on this undercarriage, and simultaneously, this undercarriage is provided with at least 3 adjustment holes, and this pin colludes the night bolt that adjustable pipe is provided with and this adjustment hole matches.
Be connected with stay cord on the described pin raker.
The present invention compares the advantage that has with prior art: 1, elastic force apparatus is longer service life, and working stability.The lie on the back critical piece of the elastic force apparatus that the rod of chair connects of strong abdomen of the present invention is spring, this spring is only in running order when person taking exercise's layback makes this spring compression, and when the person taking exercise sits up, this spring-relaxation and no longer be in stress, thereby compared to other elastic force apparatus, comparatively durable and working stability.2, function is more.Strong abdomen of the present invention is lain on the back chair outside having the function of sit-ups, and the person taking exercise can also carry out the arm strength exercise by handrail or stay cord.3, the person taking exercise who can differentiated be applicable to different heights.The lie on the back height of junction of the after-frame of chair and side arm of strong abdomen of the present invention can be regulated, and the height of this pin raker also can adjust, thereby can be applicable to the person taking exercise of different heights.
Description of drawings

Fig. 1 is the schematic perspective view at the visual angle, rear portion of embodiments of the invention;
Fig. 2 is the schematic perspective view at the anterior visual angle of embodiments of the invention;
Fig. 3 is that the master of elastic body of the present invention looks cutaway view.
The specific embodiment
Embodiment, see that Fig. 1 is to shown in Figure 3: the strong abdomen chair of lying on the back comprises side arm 11 and after-frame 12 that modes such as being down " 7 " font links together.Wherein, these side arm 11 tops are provided with support bar 20, the middle part is provided with pin raker 40; These after-frame 12 front portions are provided with cushion 30, the middle part is hinged with rod 50, and this rod 50 is provided with back cushion 51.More particularly, the rear side of this rod 50 is hinged with spring mechanism 60 by " U " shape seat 52 of going up that is fixed on this rod 50, and following " U " shape seat 121 at the rear portion of the other end of this spring mechanism 60 by being fixed on this after-frame 12 is hinged on this after-frame 12.Wherein, this spring mechanism 60 sleeve pipe 62 of comprising spring 61 and being enclosed within these spring 61 outsides.Like this, the user is when carrying out sit-up exercise, and this spring 61 is pressurized and tension repeatedly, for other elastic force apparatus, and working stability and durable.
Optimize, the below that is positioned at this cushion 30 on this after-frame 12 is provided with handrail 70, is connected with stay cord 80 on this pin raker 40.Like this, the person taking exercise is when carrying out sit-up exercise, and by means of this handrail 70, perhaps the person taking exercise only needs by means of this stay cord 80, can carry out the arm strength exercise, thereby has increased the function of this sit-ups chair.
Continue to optimize, this side arm 11 comprises that cover is plugged together puts 111 and undercarriage 112 on the shelf, and this put on the shelf 111 and undercarriage 112 between be provided with bolt-type height adjustment mechanism 113.So-called bolt-type height adjustment mechanism 113 refers to the height adjustment mechanism that cooperates by latch and pin-and-hole.Be inserted in this such as, this undercarriage 112 and put on the shelf in 111, then this undercarriage 112 is provided with some pin-and-holes, corresponding, this is put on the shelf and 111 is provided with spiral adjusting latch or spring latch, and this latch can insert in the different pin-and-holes, 111 has different height thereby this is put on the shelf.Further, this pin raker 40 is fixed in pin and colludes on the adjustable pipe 41, and this pin colludes adjustable pipe 41 and is enclosed within on this undercarriage 112.Simultaneously, this undercarriage 112 is provided with at least 3 adjustment holes 1121, and this pin colludes the night bolt 411 that adjustable pipe 41 is provided with and this adjustment hole 1121 matches.So-called night bolt 411 refers to the latch that is connected with back-moving spring.Like this, this night bolt 411 is outwards extracted, regulated this pin afterwards and collude adjustable pipe 41 to suitable height, after loosing one's grip, this night bolt 411 resets and inserts in the adjustment hole 1121 of differing heights, can make this pin raker 40 be positioned at different height.Like this, by adjusting this height of 111 of putting on the shelf, make front end and the support bar 20 of this after-frame 12 have different height, by adjusting the height that this pin colludes adjustable pipe 41, make this pin raker 40 have different height, can make this strong abdomen chair of lying on the back can differentiated be applicable to the person taking exercise of different heights.
