The specific embodiment

As shown in Figure 1 and Figure 2, the utility model is a kind of bow and arrow formula fitness equipment, and it mainly is made up of frame 1, hassock 2, hand-to-arm grip 3, damping mechanism 4, roller 5.

Described frame 1 is made of longeron 11 and underframe 12, and the lower end of longeron 11 vertically is fixed in underframe 12 middle parts.At the two ends of underframe 12 roller 5 is housed, pulley 5 is housed at the front end of longeron 11.

As shown in Figure 4, described frame 1 longeron 11 is made of loop bar 111 and sleeve pipe 112, and loop bar 111 and sleeve pipe 112 movable being plugged on together are provided with locating hole 1121 on sleeve pipe 112, be provided with a plurality of adjustment holes 113 on loop bar 111.During assembling, one in a plurality of adjustment holes 1111 on the locating hole 1121 on the sleeve pipe 112 and the loop bar 111 can be relative, plum blossom screw 113 passed locating hole 1121 and adjustment hole 1111 and with loop bar 111 and sleeve pipe 112 relative fixed.The height different according to the person taking exercise selects different locating holes 1121 to carry out relative fixed with adjustment hole 111.

Shown in Figure 2, described hassock 2 is installed on the underframe 12 of frame 1.

As Fig. 1, shown in Figure 3, described hand-to-arm grip 3 has two, and its front end is hinged on the hinged seat 13 of frame 1 longeron 11 front ends, all is provided with

arc gear wheel

31,32 on the fore end outer circumference wall of two hand-to-arm grips 3, two

arc gear wheels

31,32 are meshing with each other, and in the rear end of two hand-to-arm grips 3 roller 5 are housed.Described hinged seat 13 is the box-like body that both sides are opened wide, thereon, be arranged with two fixing holes 131 on the lower plane; Described two hand-to-arm grip 3 front ends stretch into from the open ports of hinged seat 13 both sides respectively, the through hole 33 of two hand-to-arm grip 3 front ends is relative with two fixing holes 131 on the hinged seat 13 upper and lower planes respectively, screw 15 passes the fixing hole on the plane 131 on the hinged seat 13, be placed on pad 16 in the hand-to-arm grip 3 front end through holes 33, be spirally connected with nut 17 behind the fixing hole on hinged seat 13 lower planes, make two hand-to-arm grips 3 can center on its pin joint (that is, screw 15) swing; On the upper and lower inwall of hinged seat 13, be respectively equipped with upper limit position block 133 and lower position block 134, this upper limit position block 133 plays the upwards effect (as shown in Figure 7) of the pendulum angle limit of restriction hand-to-arm grip 3, lower position block 134 plays the effect (as shown in Figure 8) of the restriction hand-to-arm grip 3 downward pendulum angle limit, thereby prevent to stretch and the radian when shrinking excessive, improve security.In the present embodiment, the angle between described roller 5 and hand-to-arm grip 3 tail ends is 90 °, and this angle can be 80-100 °.

As Fig. 2, shown in Figure 5, described damping mechanism 4 is made of two drag rope of elasticity 41, two pulleys 42, hooks 43.The middle part of described two pulleys 42 is by the rotatable side by side middle part that is installed in frame 1 longeron 11 of rotating shaft 44 (present embodiment shaft 44 is screw rod), article two, the middle part of drag rope of elasticity 41 is wire-wrapped in respectively on two pulleys 42, article two, an end of drag rope of elasticity 41 is fixed on the hook 43, and the other end of two drag rope of elasticity 41 is fixed in the middle part of two hand-to-arm grips 3 respectively.

Longitudinally be provided with a plurality of hook 43 grooves that articulate 114 that allow on described frame 1 longeron 11, described hook 43 can be articulated in one (as shown in Figure 6) in a plurality of grooves 114 of frame 1 longeron 11.Hook 43 articulates the difference of groove 114, the pulling force poundage difference of drag rope of elasticity pulling force 41.

As shown in Figure 7, when making the person taking exercise promote hand-to-arm grip 3 back and forth, frame 1 can move forwards, backwards, described hand-to-arm grip 3 is made up of three nodal axisn bars 301,302,303, oblique joining between the axostylus axostyle 302 of two ends axostylus axostyle 301,303 and centre, the extension line of two ends axostylus axostyle 301,303 and the axis of middle axostylus axostyle 302 form with triangle.

During use, the person taking exercise holds hand-to-arm grip 3 and outwards promotes, and frame 1 can move backward; As shown in Figure 8, the person taking exercise holds hand-to-arm grip 3 inwardly gos up, and frame 1 can move forward; Design of the present utility model has realized whole simultaneously forward and backward moving, and has better increased the exercise of people's body harmony.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
