Description
Technical field
The present invention relates to body-building apparatus technical field, especially relate to a kind of abdominal boards of being convenient to regulate rear plate inclination angle.
Background technology
Abdominal boards is one of extremely welcome body-building apparatus at present.Conventionally, this abdominal boards comprises side arm, after-frame, header board, rear plate and is located at the pin raker of this side arm front side.In use, person taking exercise is sitting on this header board, leans against rear plate, and ankle portion hooks on pin raker, can repeatedly carry out sit-up exercise.After further developing, in order to meet different person taking exercises' needs, or for the needs that regulate exercise intensity, the inclination angle of this rear plate can regulate.But, for regulating the most structure of adjusting device at inclination angle of rear plate comparatively complicated, operate comparatively loaded down with trivial details.
Summary of the invention
The object of this invention is to provide a kind of abdominal boards of being convenient to regulate rear plate inclination angle, the comparatively simple feature of the adjusting device structure that it has an inclination angle for regulating rear plate.Further, it also has the feature of being convenient to storage.
The technical solution adopted in the present invention is: the abdominal boards of being convenient to regulate rear plate inclination angle, comprise side arm, after-frame, header board, rear plate and be located at the pin raker of this side arm front side, the rear side of the upper end of described side arm is hinged on the downside of this after-frame front portion, this header board is fixed on the front end of this after-frame, the front end of this rear plate is hinged on the upper side of this after-frame and the hinged part of this rear plate and this after-frame is positioned at the rear of this header board, simultaneously, the bottom of this rear plate is hinged with an arc gripper shoe, the inside of this arc gripper shoe is provided with arc chute, the front side edge of this arc chute is provided with at least 2 and supports gap, and, this after-frame be provided with pass for this arc gripper shoe first pass through groove, this is first by the back shaft being provided with in groove and this support gap matches.
The top of described side arm have see through for this arc gripper shoe second pass through groove.
The advantage that the present invention has is: 1, adjusting device structure is comparatively simple.Of the present invention be convenient to regulate arc gripper shoe that the abdominal boards at rear plate inclination angle has and and the back shaft that cooperatively interacts of this arc gripper shoe formed aforesaid adjusting device, thereby used unit is less, structure is comparatively simple.Meanwhile, in the time regulating, before and after only needing, stir this arc gripper shoe, different support gap is stuck on back shaft, i.e. the inclination angle of adjustable this rear plate, very convenient.2, be convenient to storage.This side arm can fit together completely with after-frame, thereby has greatly reduced the space hold of this abdominal boards, has good storage.
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 schematic perspective view (part) of arc gripper shoe of the present invention and attaching parts thereof.
The specific embodiment
Embodiment, is shown in shown in Fig. 1 and Fig. 2: be convenient to regulate the abdominal boards at rear plate inclination angle, comprise side arm 11, after-frame 12, header board 21, rear plate 22 and be located at the pin raker 30 of these side arm 11 front sides.More specifically, the rear side of the upper end of this side arm 11 is hinged on the downside of these after-frame 12 front portions, thereby this side arm 11 can fold back and then fit together with this after-frame 12 with respect to this after-frame 12, and this side arm 11 launches forward can have a stable angle between the latter two with respect to this after-frame 12.Such as, this side arm 11 and this after-frame 12 form " people " font.This header board 21 is fixed on the front end of this after-frame 12, and the front end of this rear plate 22 is hinged on the upper side of this after-frame 12 and the hinged part of this rear plate 22 and this after-frame 12 is positioned at the rear of this header board 21.Meanwhile, the bottom of this rear plate 22 is hinged with an arc gripper shoe 40, and the inside of this arc gripper shoe 40 is provided with arc chute 41, and the front side edge of this arc chute 41 is provided with at least 2 and supports gap 42, and this support gap 42 is formed by several latches.And, this after-frame 12 be provided with pass for this arc gripper shoe 40 first by groove 121, this is first by the back shaft 122 being provided with in groove 121 and this support gap 42 matches.; in the time need to adjusting the inclination angle of this rear plate 22; only need this arc gripper shoe 40 to stir backward the inclination angle of then adjusting up and down this rear plate 22; then stir forward this arc gripper shoe 40 and make to support accordingly gap 42 and be stuck on this back shaft 122, can make this rear plate 22 there is different inclination angles.
Further say, the top of this side arm 11 have see through for this arc gripper shoe 40 second by groove 111.Like this, when this side arm 11 folds back, while being closely attached on this after-frame 12, this side arm 11 can not form and stop this arc gripper shoe 40.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; 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.
