Description
Technical field
The present invention relates to the body-building apparatus technical field, especially relate to the adjustable board for lying on back of a kind of rear plate.
Background technology
For the board for lying on back that carries out sit-up exercise, it is current very popular body-building apparatus.Usually, this board for lying on back comprises side arm and the after-frame linked together.Wherein, this side arm is provided with support bar and pin raker, and this after-frame is provided with service creeper, the front and rear panels that this service creeper arranges before and after can being.Like this, the person taking exercise faces upward and lies on this service creeper, and ankle section hooks on this pin raker, and thigh is subject to the support of this support bar, can carry out sit-up exercise.But such board for lying on back amount of exercise can't be regulated, and function is comparatively single.
Summary of the invention
The purpose of this invention is to provide the adjustable board for lying on back of a kind of rear plate, it has amount of exercise can regulate, and the comparatively various characteristics of function.
The technical solution adopted in the present invention is: the adjustable board for lying on back of rear plate, comprise the side arm and the after-frame that link together, wherein, this side arm is provided with support bar and pin raker, this after-frame is provided with front and rear panels, the front end of described rear plate is hinged at the middle part of this after-frame, and is provided with angle regulator between this rear plate and this after-frame.
Described angle regulator is: this after-frame is provided with pin pipe, and after this, front end both sides of plate are respectively equipped with 1 adjustable plate, and this each adjustable plate is provided with at least 1 adjustment hole matched with this pin pipe, and is installed with pin in this pin pipe.
Described pin pipe inside is penetrating.
Adjustment hole on described each adjustable plate is 3.
The advantage that compared to the prior art the present invention has is: 1, amount of exercise can be regulated, and function is comparatively various.In use, plate can be in the different elevations angle to the adjustable board for lying on back of rear plate of the present invention under the effect of angle regulator thereafter, and such as being in the elevations angle such as 0o, 90o, thereby the person taking exercise can access different amounts of exercise.Simultaneously, when regulate should after plate during to the 90o elevation angle, after this adjustable board for lying on back of plate also can be used as have a rest with or the stool of dumbbell training use use, thereby added new function for this rear adjustable board for lying on back of plate.2, regulative mode is simple.The angle regulator of the adjustable board for lying on back of rear plate of the present invention adopts pin to be inserted in the mode in different adjustment holes, thereby simple, directly perceived.
The accompanying drawing explanation
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is the schematic perspective view of embodiments of the invention;
Fig. 2 is the perspective exploded view (amplifying with respect to Fig. 1) of angle regulator of the present invention.
The specific embodiment
Embodiment, see illustrated in figures 1 and 2: the adjustable board for lying on back of rear plate comprises and is side arm 11 and the after-frame 12 that inverted "L" shaped or " fourth " font link together.Wherein, this side arm 11 is provided with support bar 20 and pin raker 30, and this after-frame 12 is provided with header board 40 and rear plate 50.Further say, after this, front end of plate 50 is hinged at the middle part of this after-frame 12, and is provided with angle regulator 60 between this rear plate 50 and this after-frame 12.Namely, under the effect of this angle regulator 60, should can be in the different elevations angle by rear plate 50, thereby make the person taking exercise can access Activity, and the elevation angle of plate 50 is 90o or during close to 90o after this, after this adjustable board for lying on back of plate also can be used as have a rest with or the stool use of dumbbell training use.
Further, this pin pipe 61 is inner penetrating.That is to say the open communication of these pin pipe 61 both ends of the surface.That is, use 1 pin 64 can meet the needs of angular adjustment.
Continue to optimize, the adjustment hole 63 on this each adjustable plate 62 is 3.Like this, make the elevation angle of this rear plate 50 regulate comparatively even.
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 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 scope of patent protection of the present invention.
