Description
Technical field
The present invention relates to body-building apparatus technical field, especially relate to the board for lying on back that a kind of header board is adjustable.
Background technology
Board for lying on back is current extremely welcome body-building apparatus, wherein, has a kind of Multifunctional supination bench.This Multifunctional supination bench comprises main frame body, this main frame body is fixed with service creeper, this service creeper comprises fixed header board and can regulate the rear plate at the elevation angle, and the front that the front portion of this main frame body is positioned at this service creeper is provided with foot hook frame, the underside of forward of this main frame body is hinged with front foot frame, simultaneously, on this, the bottom of foot hook frame is hinged with lower foot hook frame, the middle part of this lower foot hook frame or be connected with extension spring between bottom and this front foot frame.That is, person taking exercise faces upward and lies on this service creeper, and ankle portion hooks on this on foot hook frame, and both hands embrace head, can carry out sit-up exercise; Or person taking exercise lies on this service creeper, ankle portion hooks on this lower foot hook frame, overcomes the pulling force of this extension spring, can carry out the exercise of leg muscle.Its defect is: when after after buttress is adjusted to has the different elevations angle according to use needs, have great gap between this header board and this rear plate, thus not only attractive in appearance not, and make person taking exercise comfortable not.
Summary of the invention
The object of this invention is to provide the board for lying on back that a kind of header board is adjustable, the position that it has a header board is easy to the feature regulated.
The technical solution adopted in the present invention is: the board for lying on back that header board is adjustable, comprise main frame body, this main frame body is provided with service creeper, this service creeper comprises front and rear panels, and the front that the front portion of this main frame body is positioned at this service creeper is provided with foot hook frame, the underside of forward of this main frame body is hinged with front foot frame, simultaneously, on this, the bottom of foot hook frame is hinged with lower foot hook frame, the middle part of this lower foot hook frame or be connected with extension spring between bottom and this front foot frame, the transverse tube of trend before and after described main frame body top has, the regulating tank of trend before and after this transverse tube is provided with, this regulating tank up/down perforation, simultaneously, this header board bottom is fixed with the screw rod to downward-extension, this screw rod from top to bottom through being bolted with nut after this regulating tank.
The stopper slot of trend before and after described transverse tube is also provided with, accordingly, the bottom of this header board is fixed with the gag lever post to downward-extension, and this gag lever post is stuck in this stopper slot.
The present invention is advantageously: the position of header board is easy to regulate.The board for lying on back that header board of the present invention is adjustable when needed, only need to unscrew the nut on the screw rod being fixed on header board bottom, header board can be moved easily, thus namely after an action of the bowels the plate elevation angle regulate, gap between front and rear panels also can keep suitable size, then not only can not affect attractive in appearance, and make person taking exercise feel comparatively comfortable all the time.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the schematic perspective view of embodiments of the invention;
Fig. 2 is the front sectional view that transverse tube of the present invention and header board coordinate.
Detailed description of the invention
Embodiment, is shown in shown in Fig. 1 and Fig. 2: the board for lying on back that header board is adjustable, comprises main frame body 10.This main frame body 10 is provided with service creeper 20, and this service creeper 20 comprises header board 21 and rear plate 22.Wherein, the elevation angle of this rear plate 22 can regulate as required.The front that the front portion of this main frame body 10 is positioned at this service creeper 20 is provided with foot hook frame 30, and the underside of forward of this main frame body 10 is hinged with front foot frame 40.Obviously, this front foot frame 40 is for supporting the front portion of this board for lying on back.Like this, person taking exercise lies on this service creeper 20, and ankle portion hooks on this on foot hook frame 30, and both hands embrace head, can carry out sit-up exercise.Meanwhile, on this, the bottom of foot hook frame 30 is hinged with lower foot hook frame 50.The middle part of this lower foot hook frame 50 or be connected with extension spring 51 between bottom and this front foot frame 40.That is, person taking exercise also can lie on this service creeper 20, and ankle portion hooks on this lower foot hook frame 50, overcomes the pulling force of this extension spring 51, can carry out the exercise of leg muscle.
Further say, the transverse tube 11 of trend before and after this main frame body 10 top has.Certainly, this transverse tube 11 is mostly horizontal in use.The regulating tank 111 of trend before and after this transverse tube 11 is provided with, this regulating tank 111 up/down perforation.Meanwhile, this header board 21 bottom is fixed with the screw rod 211 to downward-extension, and this screw rod 211 this regulating tank 111 that passes from top to bottom is bolted with nut 212 afterwards.That is, after unscrewing this nut 212, this screw rod 211 can in this regulating tank 111 slide anteroposterior, then realize the movable of this header board 21.
Further say, the stopper slot 112 of trend before and after this transverse tube 11 is also provided with.This stopper slot 112 can be up/down perforation shape, also can only upper opening and the end is arranged at bottom.And this stopper slot 112 can be a part for aforementioned regulating tank 111.Accordingly, the bottom of this header board 21 is fixed with the gag lever post 213 to downward-extension, and this gag lever post 213 can being stuck in this stopper slot 112 of slide anteroposterior.Like this, avoid this header board 21 and produce rotation.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
