The specific embodiment
For the effect that describes structure of the present invention, characteristics in detail and reached, existing following preferred embodiment of act and conjunction with figs. are described as follows.
As shown in Figure 1, for manual type resistance control device provided by the invention is applied in configuration on the sports equipment 10, be to be example with the exercise bicycle herein, but the present invention also can be applicable on the indoor sport equipment of other kinds, particularly is mainly used in the elliptical machine, treadmills, the sliding steps machine that carry out lower part of the body motion ... Deng.
But sports equipment 10 has a steady rest is located at ground skeleton 11, skeleton 11 is provided with a motion 14 that is available for users to carry out limb motion, in the example of exercise bicycle, motion 14 refers to and is located at seat support 12 belows, steps on the moving pedal gear of transhipment for the user, its have can be around the same center of circle rotating relative two pedals 15.In the sports equipment of other kinds, this motion may be meant according to situation can be for the pedal gear that carries out similar road-work, the pedal gear that can move for marking time or the pedal gear that can supply to carry out the sliding steps motion ... Deng.
In addition, but also being provided with a passive movement mechanism 14 on the skeleton 11 drives and the flywheel 16 of original place rotation, for example in exercise bicycle shown in Figure 1, the size of the flywheel 16 and front-wheel of position simulation Regular Bicycle is set, and, crank shaft core pedal gear (being motion 14), and the axis part of flywheel 16, a coaxial separately affixed sprocket wheel (not shown), between two sprocket wheels around overlapping an annular link chain (not shown), so, when the user steps on commentaries on classics two pedals 15, just can drive flywheel 16 rotations by chain.What deserves to be mentioned is, in this application examples, be that two-way drive (is annotated: Regular Bicycle or some exercise bicycle between the pedal gear of exercise bicycle and the flywheel 16, the crank shaft core installing unilateral bearing of pedal gear, only step on when changeing and just can drive chain or belt) forward, just, the user steps on forward or backward changes two pedals 15, can drive flywheel 16 forward or reverse respectively, in other words, when pedal 15 and flywheel 16 one of them rotation or when static, another must be subjected to aforementioned chain restriction and rotate in the same way or static.But, in other application examples of the present invention, motion 14 may only just can drive flywheel 16 when the special exercise direction, the weight of the flywheel 16 of need not loading when counter motion just or transfixion (and rotator inertia).
The manual type resistance control device 30 of present embodiment is arranged on the top of flywheel 16, and is positioned at the dead astern of bicycle handle 13, is available for users at the volley with any proficiency one-handed performance.As Fig. 2, shown in Figure 3, resistance control device 30 mainly comprise one by a plurality of parts vertically the Control Component 40, that forms of serial connection laterally be connected elastic component 60 and between Control Component 40 bottoms and the skeleton 11 and be connected resistance assembly 70 on the elastic component 60.The top of Control Component 40 is protruding to be exposed on the skeleton 11, reverses or pushes for the user, and the bottom surface of resistance assembly 70 can press the top side side face of flywheel 16, applies predetermined frictional force.
As shown in Figures 2 and 3, the precalculated position of the skeleton 11 of flywheel 16 tops is welded with a metal catheter 21 that vertically connects, and the inner bottom of conduit 21 sets firmly a lead ring 22 in addition, makes that the aperture of pipeline bottom part is less.
Pushing and pressing bar 49 most is contained in the conduit 21, and lead ring 22 internal diameters of its shaft external diameter cooperation conduit 21 bottoms, can be along axially slippages up and down of conduit 21.The top of pushing and pressing bar 49 and the bottom butt of screw rod 44, the bottom of pushing and pressing bar 49 then convexedly stretches in conduit 21 outsides, and screws togather fixed engagement part 51.The bottom surface of fastener 51 is provided with an opening and traverse the chase 52 of left and right directions down.
Forward and backward two ends of elastic component 60 are connected to the bottom and the skeleton 11 of Control Component 40.Wherein, elastic component 60 front ends with embedding part 65 inlay cards in the chase 52 of Control Component 40 lowermost ends, elastic component 60 rear ends then lock on skeleton 11 default lugs 25, lug 25 generally is downward opening U-shaped plate (as shown in Figure 2), two wallboards with left and right sides opposing parallel, and wallboard is provided with relative perforation 26, two hook portions 64 of elastic component 60 rear ends are between the left side of lug 25, between right two wallboards, an and left side, clip between right two hook portions 64 Y-axis to spacer ring 66, utilize the perforation 26 of one first bolt, 27 lugs of break-through simultaneously 25 then, the recessed empty position of hook portion 64, and the axis hole of spacer ring 66, again tail end is locked with one first nut 28, thus elastic component 60 rear ends are fixed on the skeleton 11.
Based on default member matching relationship, elastic component 60 can provide a thrust that makes progress to Control Component 40 all the time, furthermore, even the screw rod 44 of Control Component 40 is positioned at top dead centre (only promptly going up, nut 47 fastens in the bottom face of sliding part 41) with respect to sliding part 41, the back stretch of elastic component 60 does not discharge yet fully, in other words, the front end of elastic component 60 (being embedding part 65) flexibly holder supports in pushing and pressing bar 49 bottoms (being fastener 51), make pushing and pressing bar 49 tops keep being connected to screw rod 44 bottoms, and make screw rod 44 drive sliding parts 41 to end top dead centre in scope of activities (as Fig. 3 with respect to conduit 21 cards, shown in Figure 4).
The following describes the occupation mode and the operating principle of resistance control device 30.As shown in Figure 3, Figure 4, under general state, the sliding part 41 of Control Component 40 because between receive the thrust that elastic component 60 makes progress, can remain on the top dead center position of scope of activities, at this moment, the user rotates synchronously if reverse knob 45 drive screw rods 44, because the sliding part 41 that screws togather with screw rod 44 can't rotate, and the thrust that elastic component 60 makes progress still acts on sliding part 41 by screw rod 44 always, so it is motionless that sliding part 41 can be maintained fixed substantially, screw rod 44 then can be resisted aforementioned thrust and with respect to sliding part 41 helical rotation.In this example, when the user reversed (changeing just to call in the following text) knob 45 in a clockwise direction, screw rod 44 can axially move down gradually along self, otherwise, when when counterclockwise reversing (to call counter-rotating in the following text) knob 45, screw rod 44 is understood along self and is axially moved on gradually.
When screw rod 44 during toward bottom offset, pushing and pressing bar 49 also is subjected to its pushing and pressing synchronous shift, and then, elastic component 60 embedding part 65 foremost also can be pushed against and down is offset roughly the same distance, but, because elastic component 60 has elasticity, therefore, the resistance assembly 70 that is connected elastic component 60 coil portions 61 can't move down identical distance along with embedding part 65.For example, suppose when screw rod 44 is positioned at top dead centre, the rubbing surface 75 of resistance assembly 70 does not touch flywheel 16 side faces, then continue just to change in the process that moves down gradually at screw rod 44, elastic component 60 is because front end is down pushed against, so can serve as that (annotate: this action is a strain to axle toward the pendulum that has a down dip gradually with its rear end that is fixed on the skeleton 11 earlier, be not to pivot), after the rubbing surface 75 of resistance assembly 70 gently is butted on flywheel 16 side faces, the embedding part 65 of elastic component 60 is understood beginning along with the pushing force volume production is given birth to corresponding torsional deflection with the position (i.e. second torsion bar 63) between the coil portion 61, absorb strength gap therebetween, illustrate as the imaginary line among Fig. 3, make the speed that moves down that speed is lower than embedding part 65 that moves down of coil portion 61.
Simply, the pitch (pitch) of supposing screw rod 44 is 1mm, then the user is just changeing after knob 450 circles, approximately elastic component 60 embedding part 65 foremost down can be pushed against 10mm, but by aforementioned elastic reaction, the pedestal that the coil portion 61 of elastic component 60 may only can drive resistance assembly 70 moves down 2mm, in other words, the user whenever turns round and turns around, the pedestal of resistance assembly 70 only can move down about 0.2mm, and, increase the frictional force that is applied on the flywheel 16 gradually with of the friction plate 74 past flywheel 16 side faces extruding of this speed with the bottom.
When on the user reverses knob 45 drive screw rods 44, moving, strained elastic component 60 can be replied gradually, and will push against up ejection of bar 49 with back stretch, make pushing and pressing bar 49 tops keep being connected to screw rod 44 bottoms, simultaneously, the above-mentioned answer action of elastic component 60 can drive resistance assembly 70 and up float off flywheel 16 with the rate travel that is lower than screw rod 44, reduces the frictional force that is applied on the flywheel 16 gradually.
Thus, no matter before motion or in the motion, the user all can utilize the action of reversing knob 45, be applied to frictional force on the flywheel 16 by control, rotational resistance to flywheel 16 is finely tuned, to improve or to reduce the effort degree of limb motion (for example the transhipment of stepping on of aforementioned exercise bicycle is moved).
In addition, if the user wants to make flywheel 16 to stop operating at once (particularly as should use-case at the volley, the situation that flywheel 16 in the rotation can force pedal 15 to rotate in the same way), set regardless of resistance at that time, as long as knob 45 is directly down pushed, can make screw rod 44 with moving down fast with its sliding part that screws togather 41, be pressed onto minimum point without a break by pushing against the front end of bar 49 with elastic component 60, as shown in Figure 5, make resistance assembly 70 down be driven by elastic component 60, directly, on flywheel 16, apply great frictional force, the flywheel 16 in the rotation was stopped operating in the shortest time with maximum interference compressing flywheel 16 side faces.
On the whole, in the Control Component 40 of resistance control device 30, knob 45 constitutes " operating portion " that reverses and push for the user, screw rod 44 (being provided with the section of screw thread) constitutes " threaded shank ", make Control Component 40 produce the action that spiral is advanced and retreat with respect to skeleton 11, the fastener 51 of pushing and pressing bar 49 bottoms then forms " pushing and pressing part ", and just Control Component 40 is used to push against elastic component 60 and is subjected to the oppositely position of pushing and pressing of elastic component 60.
Aforesaid operations portion, threaded shank and pushing and pressing part, for Control Component of the present invention three significant points can not or lacking, and operating portion and pushing and pressing part are connected to axial two ends of threaded shank, for example in the above-described embodiments, knob 45 is the tops (first end) that directly are connected screw rod 44, and fastener 51 is the bottoms (second end) that are connected screw rod 44 indirectly.
In addition, the elastic component among the present invention must have mutual mistake from " first position ", " second position " reach " the 3rd position ", be respectively applied for and connect skeleton, Control Component (pushing and pressing part) and resistance assembly.Obviously, in the above-described embodiments, the first torsion bar portion, 62 outer ends (being hook portion 64) of elastic component 60 constitute aforementioned first position, and the outer end of the second torsion bar portion 63 (being embedding part 65) constitutes aforementioned second position, and coil portion 61 constitutes aforementioned the 3rd position.In order to reach the above-mentioned operating principle of the present invention, first position that elastic component is used for being connected with skeleton is usually located at the wherein end of elastic component, in other words, at least second and third position must be positioned at the same side at first position, relative two sides at first position of can not living apart.In the above-described embodiments, first and second position (being hook portion 64, embedding part 65) lays respectively at relative two ends of elastic component 60, and the 3rd position (being coil portion 61) is between the two, can make the fine setting effect better, and first distance (i.e. the length of the first torsion bar portion 62) between position and the 3rd position greater than the distance between second position and the 3rd position (i.e. the length of the second torsion bar portion 63), can make above-mentioned action comparatively certain.
In the above-described embodiments, the mode that the rear end of supposing elastic component 60 changes into to articulate is connected on the skeleton 11, and aforementioned fine setting resistance and the function of very stopping fast still can reach.Only, thus, even knob 45 is inverted to peak, allow elastic component 60 unfold to the nature of not accumulating elastic force, resistance assembly 70 still can gently be pressed on the flywheel 16 with own wt, applies frictional force to a certain degree on flywheel 16, can't be as aforementioned structure, can utilize the elastic force of elastic component 60 to make friction plate 74 touch flywheel 16, even make rubbing surface 75 leave flywheel 16 side faces fully with extremely light pressure subsides.
Comparison diagram 3 and Fig. 8 are as can be known, except the sports equipment body is constant, knob 45 in the above-mentioned preferred embodiment of the present invention, screw rod 44, sliding part 41 and resistance assembly 70 also are the existing members of continuing to use fully in the well known device, and pushing and pressing bar 49 is also with to commonly use member similar.But the elastic component 60 among the present invention has but replaced intermediary's spring 92, back-moving spring 96 and lever piece 97 these three members in the well known device (as shown in Figure 8) simultaneously.Therefore, providing under the prerequisite of identical function, structure of the present invention is obviously comparatively simplified, and can reduce production costs.
As shown in Figure 6, for the structure of another embodiment of the present invention (annotate: the vitals identical or reciprocity among the figure with precedent, be marked with identical number, or in the number back additional apostrophe ('); Based on this principle, some parts will can not remake unnecessary description hereinafter), the resistance control device 30 that present embodiment provided ' with the precedent maximum different, be to give up the function of stopping except quick evil spirit, promptly, there is not sliding part 41 in the present embodiment, the substitute is in conduit 21 inside and establish a thread-hole part 29, and make Control Component 40 ' threaded shank 44 ' screw togather with thread-hole part 29, so, threaded shank 44 ' still can advance and retreat by spiral with respect to skeleton 11, but can't (not by spinning movement) direct axial slip.In addition, by threaded shank 44 ' bottom down one extend a stock portion 53, just two members in the precedent (screw rod 44, pushing and pressing bar 49) are simplified and merged into solid memder, simultaneously, elastic component 60 ' front end just holder be against the pushing and pressing part 51 of Control Component 40 ' bottom ', do not form chimeric.Other members in the present embodiment are identical with precedent, repeat no more.Pass through said structure, when 45 ' time of user's forward or reverse operating portion, Yi Bian move down Yi Bian Control Component 40 ' integral body can just changeed, or on reversing, move, based on the aforementioned activities principle, make be connected elastic component 60 ' on resistance assembly 70 ' with slower speed near or leave flywheel, reach the basic purpose of fine setting resistance.
Subsidiary one carries, screw rod 44 among Fig. 3 and pushing and pressing bar 49 also may be simplified and merge into solid memder (annotate: but its bottom is wanted and can be rotated freely with respect to elastic component 60, therefore chase 52 inlay card elastic components 60 front ends can not be set), this with threaded shank directly axial slip do not have related.
Be noted that at last, for the purpose of the present invention, when the threaded shank of Control Component does not possess along axially directly (for example structure of Fig. 6) during the function of slippage, Control Component does not just limit affixed with threaded shank for the operating portion that the people reverses, for example, mode that can't axial displacement but operating portion is with original place rotation is hubbed on the skeleton, the mode that can't rotate is arranged on the skeleton but threaded shank then is with axial displacement, and with the default screwhole spiro bonding of operating portion shaft core position, thus, the forward or reverse operating portion also can drive threaded shank with respect to skeleton along self axially near or away from flywheel.
