For expanding function, many manufacturers improve this exercising apparatus for abdomen.That is such exercising apparatus for abdomen, by between this rod and this after-frame, angular stop means being set, makes this rod can be stable at different angles, thereby makes this exercising apparatus for abdomen have the function of board for lying on back concurrently, so also can be described as the exercising apparatus for abdomen of lying on the back.But the angular stop means structure of the exercising apparatus for abdomen of much lying on the back is reasonable not, and is stable not when causing this rod work.
Summary of the invention
The purpose of this invention is to provide a kind of exercising apparatus for abdomen of lying on the back, it has rod comparatively stable characteristics of when work.Further, it also has back cushion comparatively comfortable characteristics when using.
The technical solution adopted in the present invention is: the exercising apparatus for abdomen of lying on the back, comprise the side arm and the after-frame that link together, this side arm is provided with support bar and pin raker, this after-frame front portion is fixed with seat cushion, the rear portion is hinged with rod by hinge, and the top that is positioned at this hinge on this rod is provided with back cushion, this rod is connected with extension spring between the rear portion of the end below this hinge and this after-frame, described after-frame has the clamping gap, this rod is clipped in this clamping gap, simultaneously, be welded with fan-shaped adjustable plate on the trailing flank of this rod, this fan-shaped adjustable plate is provided with at least 2 adjustment holes, and have on this after-frame and pin-and-hole that this adjustment hole matches, be inserted with latch in this pin-and-hole.
Described back cushion comprises the pivot that is welded on this rod, and the cover of the outside interference fit of this pivot has rotating cylinder, and the outer cover of this rotating cylinder has soft cover.
Described soft cover is sponges cover or rubber sleeve.
Described rotating cylinder is plastic barrel.
The present invention is compared with existing technology the advantage that has: comparatively stable when 1, rod is worked.The mode that the angular stop means of the exercising apparatus for abdomen of lying on the back of the present invention adopts adjustment hole on the fan-shaped adjustable plate that the rear portion of this rod arranges and the pin-and-hole on the after-frame to cooperate, and this rod is clipped in the clamping gap of this after-frame, thereby the globality of this rod and this after-frame is better, thereby be difficult for rocking when making this rod work, comparatively stable.It is comparatively comfortable when 2, back cushion uses.Soft cover on the back cushion of the exercising apparatus for abdomen of lying on the back of the present invention can carry out smooth rolling along user's back, thereby has increased the level of comfort at user back.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is the perspective view of embodiments of the invention;
Fig. 2 is the perspective view of the part of embodiments of the invention.
The specific embodiment
Embodiment, see illustrated in figures 1 and 2: the exercising apparatus for abdomen of lying on the back comprises being side arm 11 and the after-frame 12 that " 7 " font or " fourth " font link together.Wherein, this side arm 11 is provided with support bar 20 and pin raker 30; These after-frame 12 front portions are fixed with seat cushion 40, the rear portion is hinged with rod 60 by hinge 50, and the top that is positioned at this hinge 50 on this rod 60 is provided with back cushion 70, and this rod 60 is connected with extension spring 80 between the rear portion of the end below this hinge 50 and this after-frame 12.That is, the person taking exercise can be good for the abdomen exercise by this exercising apparatus for abdomen of lying on the back.
Say that further this after-frame 12 has clamping gap 121.Such as, this after-frame 12 is welded together side by side by 2 identical square tubes, and has certain slit between these 2 square tubes, and this slit namely forms this clamping gap 121.At this moment, this rod 60 is clipped in this clamping gap 121.Certainly, the two ends of this hinge 50 are positioned on the two side in this clamping gap 121.Simultaneously, be welded with fan-shaped adjustable plate 61 on the trailing flank of this rod 60, this fan-shaped adjustable plate 61 is provided with at least 2 adjustment holes 611, and has on this after-frame 12 and pin-and-hole 122 that this adjustment hole 611 matches, is inserted with latch 123 in this pin-and-hole 122.That is, this pin-and-hole 122 can be aligned with respectively different adjustment hole 611, afterwards this latch 123 is inserted, and can make between this rod 60 and the horizontal line and be stable at certain angle.Such as, the angle between this rod 60 and the horizontal line is stable at about 90o, about 115o, about 180o.Like this, when this rod 60 was stable at the 90o left and right sides, this exercising apparatus for abdomen of lying on the back was equivalent to form a dumbbell chair; When this rod 60 was stable at 115o and the 180o left and right sides, this exercising apparatus for abdomen of lying on the back was equivalent to form a board for lying on back.That is, this exercising apparatus for abdomen of lying on the back has more function.Simultaneously, the globality of this rod 60 and this after-frame 12 is better, thereby is difficult for rocking when this rod 60 is worked, and is comparatively stable.
Optimize, this back cushion 70 comprises the pivot 71 that is welded on this rod 60, and the cover of the outside interference fit of this pivot 71 has rotating cylinder 72, and the outer cover of this rotating cylinder 72 has soft cover 73.This soft cover 73 can be sponges cover, rubber sleeve etc., and this rotating cylinder 72 can be plastic barrel.Like this, the soft cover 73 on this back cushion 70 can rotate in company with this plastic barrel 72, has avoided the situation at these soft cover 73 rigid friction user backs, thereby has increased the level of comfort at user back
The above only is the preferred embodiments of the present invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
