Detailed description of the invention
Embodiment, as shown in Figure 1: with the board for lying on back of chest expander, comprises the L-shaped side arm 11 that links together and after-frame 12.Certainly, the bottom of this side arm 11 and this after-frame 12 all arranges feet.Meanwhile, the front portion of this side arm 11 top or this after-frame 12 is provided with support bar 20, and the bottom of this side arm 11 is provided with pin raker 30, and this after-frame 12 is provided with service creeper 40.
Further say, on front side of the upper end of this side arm 11, be articulated with a puller system 50.That is, the elevation angle of this puller system 50 can regulate.This puller system 50 comprises body 51, and the inner of this body 51 is articulated on this side arm 11, and is provided with stopping means between this body 51 and this side arm 11.That is, this body 51 can be stable at steeving on position of needs.Meanwhile, be provided with in this body 51 and have flexible stay cord 52, the free end of this stay cord 52 is positioned at the outer end of this body 51.That is, person taking exercise is sitting on this service creeper 40, pulls or promote with pin the free end of this stay cord 52, can perform physical exercise to arm or leg muscle.Preferably, for the ease of coordinating foot and hand, the free end of this stay cord 52 is connected with tape 561 or handle 562 by knot that can be undone by a pull 53.
Continue to optimize:
Shown in composition graphs 7, the stiff end of this stay cord 52 is connected to the outer end of this body 51.Meanwhile, the inner end of this body 51 is provided with the first fixed pulley 551, and the outer end of this body 51 is provided with the second fixed pulley 552, and this first fixed pulley 551 and this second fixed pulley 552 walked around successively by this stay cord 52.Like this, adopt less length, longer stay cord 52 can be used, make the structure of this puller system more compact.
Shown in composition graphs 2, this stopping means is: this side arm 11 is provided with at least 2 spacing holes 111, and the inner end of this body 51 is provided with the pin-and-hole 54 matched with those spacing holes 111.That is, this pin-and-hole 54 can align certain spacing hole 111 as required, and is inserted with latch 60 in this pin-and-hole 54 and the spacing hole 111 that aligns with it.Like this, by comparatively simple mode, this body 51 is made to have the suitable elevation angle.Obviously, the horizontal level residing for the free end of this body 51 is lower, then person taking exercise to overcome the pulling force of stay cord 52 larger, thus exercise intensity is larger.
Shown in composition graphs 8, the trailing flank of this side arm 11 is provided with 2 clamps 1121 in vertical shape extended back, and these 2 clamps 1121 are stuck on 2 vertical sides of this after-frame 12.Meanwhile, between the downside of these 2 clamps 1121, be connected with a level board 1122, the downside of the leading section of this this after-frame 12 of level board 1122 close contact.And the leading section of this after-frame 12 is connected between these 2 clamps 1121 by a connecting bolt 121 and a pin 122.That is, these 2 clamps 1121 and this level board 1122 surround three of the leading section of this after-frame 12 sides, thus make the connection of this after-frame 12 and this side arm 11 comparatively tight, and structure is comparatively stable.Certainly, the leading section of this after-frame 12 is square.
Shown in composition graphs 3 to Fig. 6, this service creeper 40 comprises header board 41 and can regulate the rear plate 42 at the elevation angle.Like this, when this rear plate 42 puts down, be convenient to person taking exercise and carry out sit-up exercise, and when this rear plate 42 is lifted, have one between this header board 41 and this rear plate 42 and be greater than the angle that 90 ° are less than 180 °, thus make this service creeper 40 form a stool, be convenient to person taking exercise and carry out pulling force exercise.In the present embodiment, shown in composition graphs 9, the front side edge of this rear plate 42 is hinged on this after-frame 12, and the bottom of this rear plate 42 is hinged with a pole 43, and the other end of this pole 43 is hinged on a sleeve pipe 44 be enclosed within this after-frame 12.Meanwhile, this after-frame 12 is provided with at least 2 adjustment holes 123, and this sleeve pipe 44 is provided with the spring catch 45 matched with those adjustment holes 123.That is, this spring catch 45 inserts in different adjustment holes 123, makes this sleeve pipe 44 be stable at certain position, then makes this rear plate 42 have certain elevation angle.Such regulative mode is simple, reliable.
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.
