Abstract
An exercising apparatus is provided with a body. The body is pivoted with at least one rope sheave for a pull to wind. The rope sheave is provided with a reset mechanism which drives the rope sheave to furl the pull that is pulled out. The rope sheave is connected with a shaft and the shaft is connected with a single-direction mechanism which drives an impedance wheel with adjustable resistance at single direction during the journey that the pull drives the rope sheave to rotate. The apparatus moves when the consumer uses a pull. The utility model drives the rope sheave to furl the pull that is pulled out by the reset mechanism so as to avoid the consumer to be injured during the journey that the pull is drew back. And as the body is provided with a friction adjusting device corresponding to the impedance wheel, the utility model changes the power that a friction belt to resist the impedance wheel through a rotating adjusting bolt so as to reach the effect of changing the amount of exercise.

Five, the specific embodiment:
See also Fig. 1 to Fig. 6, the utlity model has a body 1, these body 1 both sides respectively are extended with a pedal 11, each pedal 11 has a grip part 12 respectively away from an end of this body 1, this body 1 respectively is pivoted with a rope sheave 13 with two 16, each rope sheave 13 supplies a stay cord 14 windings respectively, and each rope sheave 13 has the accommodation space 131 of an indent respectively, so that a spiral spring 15 to be set respectively.Each spiral spring 15 has an outer end 151 and a inner 152 respectively, and these outer end 151 hooks are located at this rope sheave 13, and 152 hooks in this inner are located at one and are arranged on the pin 17 of this body 1 near axle 16 places, and each 16 links a unidirectional mechanism 18 respectively.This unidirectional mechanism 18 is a unilateral bearing 18 in the present embodiment, borrows each unilateral bearing 18 unidirectional drive one resistance mechanism of difference in the stroke of stay cord 14 drive rope sheaves 13 rotations, and this resistance mechanism is to adopt a friction pulley 19 in the present embodiment.
This body 1 corresponding each friction pulley 19 is provided with a frictional force adjusting device 2, this frictional force adjusting device 2 has the friction that a circle is around in these two friction pulleys, 19 outer rims and is with 21, this friction is to be fixed in a sliding seat 22 with 21 two ends, this sliding seat 22 is set on the slide block 23, this slide block 23 has two protuberances 231 with in the chute 101 that is embedded at body 1 respectively, this slide block 23 is to revolve lock mutually with an adjustment bolt 24, and 22 of this slide block 23 and this sliding seat are provided with a spring 25, borrowing this adjustment bolt 24 of rotation to drive this slide block 23 moves, compress sliding seat 22 to change the strength of these sliding seat 22 drawing friction bands 21 conflicts two friction pulleys 19 with this spring 25 of pushing tow, adjust the frictional resistance that changes this two friction pulley 19.
This body 1 corresponding each stay cord 14 is respectively equipped with a guide mechanism 3, this guide mechanism 3 has a rotation seat 31 that is hubbed at this body 1 and can rotates freely, this rotation seat 31 has a hole of axially running through 32, wear for this stay cord 14, the end that this stay cord 14 passes rotation seat 31 is combined with leader 141, and this hole 32 is defined as the port of export 321 for the end that stay cord passes.The port of export 321 of this rotation seat 31 in this hole 32 is pivoted with a pulley 33 and wears a pin 34, the spacing that this pulley 33 and this pin are 34 only allows that this stay cord 14 passes through, so that this stay cord 14 is subjected to the restriction of pin 34 and is around on this pulley 33, this stay cord 14 is drawn out or when being furled, this rotation seat 31 can rotate thereupon, and guides these stay cords 14 to reduce the resistance that stay cord 14 is advanced by this pulley 33.
See also Fig. 7, during use, the user can trample on pedal 11 by both feet, and hold handle 141 on each stay cord 14 with both hands, when user's application of force pulling stay cord 14 drives rope sheave 13 rotations, this spiral spring 15 of meeting rolling-in, and via 19 rotations of the 18 drive friction pulleys of the unilateral bearing on the axle 16.Because friction pulley 19 is with 21 to conflict by friction, therefore, when the user spurs stay cord 14, need application of force antagonism friction pulley 19 and rub with 21 frictional force, reach the effect of motion whereby.As user no longer during the application of force, just can be driven rope sheave 13 by the restoring force of this spiral spring 15 furls stay cord 14, because the design of this spiral spring 15 only need retract stay cord 14, therefore can make torsion lower, to avoid causing user's load, and rope sheave 13 is in the stroke that furls stay cord 14, this 16 and 18 of unilateral bearings be the forms of idle running, and can not drive friction pulley 19, so when stay cord 14 was pulled, the user only needed the slight application of force just can resist the restoring force of spiral spring 15, and can in the stroke that rope is pulled back, not cause unnecessary athletic injury as the structure of commonly using.
Certainly, the user can adjust the position of this slide block 23 according to this adjustment bolt 14 of required rotation, to change the thrust that slide block 23 goring push springs 25 promote sliding seat 22, thrust is bigger, then sliding seat 22 can be with friction 21 to draw tightlyer, make friction bigger, and produce bigger drag, make the user can obtain bigger amount of exercise with the power of 21 conflict friction pulleys 19; And will reduce frictional resistance the time, then oppositely adjust according to aforesaid method and get final product.
Spur in the process of stay cord 14 the user, because this stay cord 14 is holes 32 of passing in this rotation seat 31, and the spacing that pulley 33 that is pivoted on these hole 32 ports of export 321 and pin are 34 is only held this stay cord 14 and is passed through, make this stay cord 14 be subjected to the restriction of pin 34 and keep being around on this pulley 33, therefore, no matter the user is when any direction pulling stay cord 14 or stay cord 14 are furled, this rotation seat 31 all can with rotation, and rotate this stay cord 14 of guiding by this pulley 33, and the resistance can reduce stay cord 14 and advance the time, and stay cord 14 can be pulled out by any direction, carry out various stay cord action and can be convenient to the user.
Except aforesaid motion mode, the user can also hold two grip parts 12 of body 1 by both hands, and is arranged in respectively with both feet on the handle 141 of stay cord 14, and as shown in Figure 9, so, the user just can spur the effect that stay cord 14 reaches the motion both feet by both feet.
In sum, the utility model mainly be with axle 16 that this rope sheave 13 links on be provided with a unilateral bearing 18 and be connected a friction pulley 19 drive friction pulleys 19 by unilateral bearing 18 in the stroke that stay cord 14 drives rope sheaves 13 rotations and move so that spur the user.This rope sheave 13 also is provided with a spiral spring 15, furls the stay cord 14 that is drawn out to drive rope sheave 13 by this spiral spring 15, and avoids the user to be pullled injured problem at stay cord 1 by in the stroke of pulling back.Moreover 1 pair of this body should be provided with a frictional force adjusting device 2 by friction pulley 19, changes the strength of friction with 21 conflict friction pulleys 19 and adjust bolt 24 by rotation, to reach the effect of varying motion amount.
