Saddle 15 is installed in the upper end of saddle pillar 14, the user of these saddle 15 supporting exercising devices.Saddle in the embodiment of the invention has the general shape and the feature of saddle standard bicycle or similar, and in order to adapt to the long trainee of different heights and leg, saddle 15 is adjustable with respect to base 11 in vertical.In described embodiment, this adjusting is finished by pillar 18.In the upper end 19 of the hollow of pillar 18 telescopicallies insertion saddle pillar 14,19 places in the upper end, pillar 18 can be finished by any proper device along the adjusting of vertical, and for example screw clamping device 20, and this mounting technique field at bike saddle or similar saddle is known.

A pair of pedal 22 and 23 is installed on the base 11, each pedal is positioned at the both sides of the opposite external side face of saddle pillar 14 and vertical part 13, pedal 22 and 23 has enough width, to be easy to admit the pin that is sitting in the people on the saddle 15, the width of pedal is advisable with 4-5 English inch, but this is not restriction.Pedal 22 and 23 rear end 24 link with the corresponding hinge 25 of the rear end 27 of contiguous exercising device base 11.In described embodiment, each pedal 22 and 23 extends forward from separately hinge 25, until near the front end 28 base 11 front ends 29.

Two pedals 22 and 23 are coupled to each other together, when a pedal is depressed, and another rising, vice versa.Pedal 22 and 23 thisly replace reciprocal motion and provided by main drive belt 32, the end of belt 32 links at position and each pedal of contiguous pedal front end 28 respectively.In this embodiment, main drive belt 32 is a toothed belt, and it extends upward from pedal 22, has walked around toothed belt wheel 33R, and bottom belt pulley with tooth 34 engagements of extension and synchronous belt wheels 35 forward thus.Belt pulley 34 links by the top belt pulley 53 of following mode and synchronous belt wheels 35, stacked belt pulley 34 and 35 rotates on a upright bolster together, main drive belt turns over about 180 ° around belt pulley 34, move backward thus and see Fig. 3 with toothed belt wheel 33L(is arranged) be meshed, turn to below and left-hand tread plate 23 to link again.So, as the people who uses described exercising device 10 downwards during pushing one pedal, around belt pulley 33R, 34 and the main drive belt wheel 32 of 33L motion will this downward motion convert the motion that makes progress of another pedal to.

Between the upper end of vertical part 12 and 13, be provided with a horizontal stand 37, a flywheel 39 is installed on this horizontal stand, flywheel 39 is omitted in Fig. 1 by safety guard 35(fully) surround, be provided with some blades that radially extend 40 on this flywheel, these blades are quite big perpendicular to the frontal projected area on the plane of flywheel vertical guide, when flywheel 39 rotates, flywheel blade 40 with energy dissipation in air.More detailed description sees below.

Flywheel 39 is installed on the axle 41, and insert in the corresponding output block of two flywheel clutches 44 and 45 at this two ends.Described clutch is also referred to as one-way clutch usually.These clutches 44 and 45 respectively have an input block, and they link with belt pulley 33R and 33L respectively.Utilize the flywheel clutch of this pattern, its output block can be to a direction rotation under the effect of a driving force, but, this clutch only responds to the input of direction rotation and power is delivered to output block, when the power of input was interrupted or is reverse, input block only dallied with respect to output block.The details of this clutch is known, repeats no more herein.

A pair of training bar 54 and 55 is used to train arm and the shoulder that is sitting in the user on the saddle 15, and they are installed in rotation near the front end of base 11. Training bar 54 and 55 pivoting levers 57 from base 11 extend upward, and pass through in the circle of driving belt 32 front portions, stop with horizontal hand grip 56 in the upper end of described training bar, and handle 56 stretches out from the training bar, so that user's grasping.Handle can push-and-pull mode move back and forth along giving fixed largest motion camber line, pivoting lever 57 is mounted to and can moves forward and backward along base 11 within the specific limits, so that change the position of handle 56 with respect to saddle 15 selectively.

Training bar 54 and 55 links with connecting rod 51 and 52 respectively, connecting rod 51 and 52 is connected on the toothed handlebar driving belt 58, this driving belt is walked around the roller 50 on the column of the rear end top that is contained in horizontal stand 37, and extend forward the both sides at flywheel 39, so that have toothed belt wheel 53 to be meshed with the top of aforementioned synchronous belt wheels 35.The upper and lower belt pulley 53 and 34 of belt pulley set 35 is coupled to each other is in the same place, and like this, the rotation that main drive belt 32 produces belt pulley just drives upper belt pulley and handlebar driving belt 58, and vice versa.

Operation below with reference to exercising device shown in Fig. 1-3 explanation, earlier suitably regulate saddle pillar 18, the user is sitting on the saddle 15 then, and both feet rest on two pedals 22 and 23 naturally, if desired, the user also can hold the handle 56 of two training bars 54 and 55.The user presses next pedal 22 earlier, depresses 23, two pedals of another pedal then and moves back and forth with regard to alternatively up and down.The main drive belt 32 that pedal 22,23 is linked up has been walked around toothed belt wheel 33R, there is toothed belt wheel 34 bottom and toothed belt wheel 33L is arranged, guarantee when pressing next pedal, another pedal is risen in a kind of alternately up and down reciprocatingly mode of association.

When main drive belt 32 and belt pulley 33R, 33L driving one-way clutch 44, the downward stroke of each of arbitrary pedal all will rotatablely move and pass to flywheel 39.At each pedal, for example pedal 22, in the process that moves upward, main drive belt 32 drive pulley 33R, simultaneously, one-way clutch 44 makes the (see figure 1) rotation along clockwise direction of this belt pulley, and the rotating counterclockwise mutually of flywheel 39 that causes with being moved downward by aforementioned another pedal 23 do not disturbed.

Depress in two pedals 22 and 23 at every turn, also make training bar 54 and 55 change the position along its camber line that moves.For example, when pedal 22 moves downward, main drive belt 32 make the bottom have toothed belt wheel 34 to rotate the time, top toothed belt wheel 53 is arranged with the direction handle bar driving belt 58 identical with main drive belt.The motion of this driving belt 58 will train bar 54 to pull back to the user through the transmission of connecting rod 51 and 52, and another training bar 55 is pushed away the user forward, then, another pedal 23 moves downward, and makes aforementioned training bar 54 and 55 to swing in the other direction, returns position shown in Figure 1.Equally, the user can alternately push away, pull bar 54 and 55, and this active force is delivered to main drive belt 32, and then drives flywheel 39.

Because main drive belt 32 has acted on toothed belt wheel 33R and the 33L with a constant lever arm (being each radius that the toothed belt wheel is arranged), each pedal 22 and 23 whole downward stroke apply power with essentially identical ratio, and flywheel 39 is rotated.Thisly differ widely for the effect pedaled of stepping on of the foot-operated exercising device in zero-bit or dead point district for driving constant effect that flywheel 39 applied and the summit that typically has bicycle crank device, each pedal travel and end point, and the belt drive unit of exercising device of the present invention has been avoided this zero-bit district, and all do work from start to finish during the each press foot pedal of user (and consumed energy).Constant force is the same with user's push-and-pull training bar institute work to the merit done of training bar in each training throw of lever, because the radius ratio bottom belt pulley 34 of top belt pulley 53 is little, so the useful work that each pole pair flywheel 39 is done reduces.

Fig. 4-6 is depicted as another exercising device 78, and its utilizes pedal and the driving belt mechanism identical with training tool 10, represents the parts identical with previous embodiment with identical label among the figure.Exercising device 78 usefulness one friction catch band mechanism 79 replaces flywheel 39 and the blade 40 among first embodiment, and the energy absorbing device that is driven by pedal 22,23 and training bar 54,55.

Brake band mechanism 79 comprises a flywheel 80 with smooth external peripheral surface 81, and this surface 81 preferably has shallow slot, so that cooperate and keep engagement with the lateral edges of brake band 82.Brake band 82 engages with outer round surface 81.Flywheel 80 should have enough weight so that the moment of torsion that applies thereon by pedal and training bar is stably changed.

Brake band 82 is walked around the relative little belt pulley 85 with torque load of flywheel 80, and belt pulley 85 is installed in the flywheel back of vertical part 13 upper ends.In this embodiment, brake band 82 neither is connected with flywheel 80, also is not connected with the small belt pulley 85 that bears moment of torsion, and the two ends 84 and 86 of brake band 82 are fastened to the upper end of the torque stand 87 that is positioned at flywheel 80 tops.Torque stand 87 will further specify hereinafter, and clearly, the belt pulley 85 and the brake band 82 that bear moment of torsion move minimum.

The belt pulley 85 that bears moment of torsion is installed on the support 91 of pull bar 92 upper ends, and bar 92 extends upward from the hinge 93 that is fixed on the base 11 that is close to vertical part 13 front portions.Torque loads adjusting knob 94 in vertical part 13 back matches with the screw rod 95 that passes vertical part, and a spiral tension spring 97 is connected to screw rod on the pull bar 92.Manual adjustments knob 94 can increase the elastic force of spring, the support 91 of pull bar 92 upper ends and the rack-mount belt pulley that bears moment of torsion 85 to pusher.

Torque stand 87 restriction brake bands 82 are done angular movement and transverse movement on flywheel 80, and transfer torque to and be installed near the torque sensor 100 the torque stand lower end on the base 11.Torque stand 87 extends downwards in the left and right sides of flywheel 80, and freely rotates on the bolster 41 of flywheel 80.Because the end 86 of brake band 82 is fixed on the torque stand 87, the lower end that makes torque stand that is frictionally engaged between the flywheel 80 of brake band and (as shown in Figure 5) rotation is in the counterclockwise direction pushed away forward, shown in arrow 101.The push rod 102 of torque sensor 100 bears and resists this mechanical force that transmits from torque stand 87.

The structure of torque sensor 100 as shown in Figure 6, but people know, traditional pressure sensor or spring load rheostat can replace pneumatic transmitter 100.This torque sensor comprises a housing 105 that inner chamber 106 is arranged, inner chamber 106 comprises a diaphragm 107 that dangles and do finite motion in this chamber, push rod 102 can move freely in the path 10 8 of housing 105 1 sides, and the inner of push rod leans on the sealing ring 110 that is installed on diaphragm 107 central authorities.Sealing ring 110 has an axial passage 111, the axial escape orifice centering on this passage and the push rod 102.

Diaphragm 107 is with inner chamber 106 separated into two parts, and the only link between these two parts is the passage 111 in the diaphragm seal circle 110.The inner 116 of needle valve 117 contacts with sealing ring 110 on inner 109 opposites of push rod.This needle valve has but a main valve body 118 that diameter bigger coaxial with inner 116, and this main valve body can insert in the duct coaxial with it 119 loosely, and hole 119 communicates with compressed air source through air supply pipe 120.

The inner 116 of needle valve 117 can be inserted the inside in duct 119 loosely, and a transverse holes 123 makes described endoporus 119 link with air duct 124, and air duct 124 is communicated with the right side 125 and the air signal circuit 126 of diaphragm chamber 106.The air signal link tester is to a suitable air pressure probe 127, this sensor can come scale with suitable unit, the pound of moment of torsion-Foot value for example, perhaps (if the words that link with a time movement) come scale with the power that the people consumed that uses this exercising device.

The operation of the exercising device shown in Fig. 4-6 is discussed below.The user pays energy pumps pedal 22,23, perhaps pushes away, draws training bar 54,55, perhaps the two dual-purpose, and this motion provides moment of torsion, overcomes the frictional resistance that is applied by the brake band on the flywheel surface 81 82 flywheel 80 is rotated.The big I of this frictional resistance is regulated by knob 94, and knob 94 increases or reduces to make torque loads belt pulley 85 to leave the spring tension of flywheel 80.When flywheel 80 rotates, the frictional force that acts on brake band 82 is applied on the torque stand 87 by the end 84 and 86 of brake band, therefore, the push rod 102 of the lower end press pressure sensor 100 of torque stand 87, make push rod inwardly motion contact with diaphragm 107, and promote this diaphragm and contact with the inner 116 of needle valve 117.

This mechanical movement of needle valve 117 makes the valve cone face 130 on the needle valve 117 between the inner 116 of main valve body 118 and needle valve 117 produce micro displacement, makes air enter the right side 125 of diaphragm chamber 106 from air supply pipe 120.The air pressures that increase in the right side 125 act on the diaphragm 107, diaphragm is pushed to push rod 102 make every effort to overcome until diaphragm and obeyed the power that is caused by moment of torsion on the push rod, so diaphragm 107 to left movement as shown in Figure 6.Because valve body 118 right-hand members 131 have the cross-sectional area bigger than the valve cone face 130 of needle valve, in aciculiform valve pocket 119, the air pressure that increases forces needle valve to left movement, and keeps needle valve inner 116 to contact with diaphragm seal circle 110, thereby has blocked the passage 111 in the sealing ring.Yet, if the caused motion of membrane of air pressure that increases in 106 right sides 125, chamber surpasses the stroke (the trip is determined) of the qualification of needle valve 117 when valve cone face 130 leans against valve cup bottom, passage 111 is just opened, and releases air pressure in the atmosphere in the duct 112 of releasing on push rod 102.Have only in the time need averaging out with the power that acts on the increase on the push rod 102, sensor just utilizes the air in the air supply pipe 120.The power that acts on the push rod 102 makes diaphragm turn back to a position, in this position, acts on the power that the air pressure on diaphragm right side and push rod 102 act on the diaphragm left side and balances each other.Because air signal circuit 126 transmits and makes the needed air pressure of diaphragm balance, the air pressure that plays balanced action is to weigh a kind of yardstick of push rod 102 being pressed to the power relevant with moment of torsion of diaphragm, thereby the air pressure person of being to use who plays balanced action in the signal line 126 is applied to the function of the power on the exercising device at any one time.Air pressures relevant with this power in the signal pipe 126 are by output device 127 demonstrations, as previously mentioned, this device can with relevant with merit or power, come indexing for the significant noun of user.

Fig. 7-9 expression is according to the exercising device 138 of third embodiment of the invention, and with previous embodiments, exercising device 138 comprises a base 11, and the saddle pillar 14 of band saddle 15 is housed on it.Yet exercising device 138 does not have the such pedal of previous embodiment, is constrained on the pedal that slidably reciprocates on the track of a regulation along with the pressure of pin and replace.Operation with pedal among the aforementioned embodiment is the same, and the pedal of exercising device 138 makes the user can apply the power of acting equably in whole pedal travel, and the right-side pedal of this apparatus is represented by 139R.

One of exercising device 138 usefulness are contained in fan 140 on vertical fan shaft 141 as load, and the people uses this apparatus to overcome this load acting.Fan shaft 141 is contained in the front end of transmission mechanism 142, this mechanism comprises the column 143 and 144 that is arranged along vertical branch of base 11, back timber 145 extends between the upper end of column 143 and 144, usually in the both sides of post 143,144 and back timber 145 suitable side plate is installed, the moving component of transmission mechanism is covered, for the sake of clarity, these plates have been omitted among Fig. 7.

A pair of spaced preceding slide bar extends to base 11 vertically downward from back timber 145, and the upper/lower terminal stationary positioned, only can find out right front slide bar 149R from Fig. 7, and Fig. 9 has represented left front slide bar 149L.A pair of back slide bar 150R, 150L also vertically extend between back timber 145 and base, and the spacing between the slide bar of front and back can be clear that from Fig. 8.Right-hand tread plate slide block 152R and left-hand tread plate slide block 152L are installed in respectively on preceding slide bar 149R, 149L and back slide bar 150R, the 150L.Pedal slide block 152R and 152L are slidably mounted on the slide bar by the ball bearing of traditional design, so that slide block freely pumps along slide bar, and make the frictional resistance minimum.

Preceding driving belt 154 and back driving belt 155 are contained between pedal slide block 152R and the 152L, and link with slide block, driving belt 154 and 155 is preferably foregoing a toothed belt, these belts respectively with transmission mechanism 142 upper ends near the toothed belt wheel 156 and 157 that has accordingly be meshed.Driving belt 154 and 155 is walked around optional loose pulley 158, this belt pulley is installed near the lower end of transmission mechanism 142, and help to keep the driving belt tension, owing to the appropriate exercise that can keep driving belt that connects each other of pedal slide block, these loose pulleys also can save.

The assembling of forward and backward driving belt and pedal slide block 152R and 152L sees Fig. 8 for details.The left side 154L of preceding driving belt is fixed on the inboard 162 of left-hand tread plate slide block 152L, and the right 154R of preceding driving belt is fixed on the inboard 163 of right-hand tread plate slide block 152R.Suppose that right-hand tread plate 139R moves downward, the right 154R of driving belt 154 moves downward before making, and the left side 154L of this driving belt is risen, and left-hand tread plate slide block 152L and the pedal 139L that links with it also rise so.

Each pedal slide block 152L and 152R have the extension on the corresponding opposite that is arranged on back driving belt 155, left-hand tread plate slide block 152L have one be fixed to the back driving belt the right 155R on extension 164, same, the extension 165 after right-hand tread plate slide block 152R has to be fixed on the left side 155L of driving belt.Obviously, press next pedal, pedal 139L for example, thereby not only resemble make foregoing before driving belt 154 motion rising right-hand tread plate 139R, and back driving belt 155 is moved along the direction opposite with preceding driving belt.This motion of back driving belt 155 successively through the extension 165 and right-hand tread plate slide block 152R be delivered to right-hand tread plate 139R.

Link with the importation of corresponding one-way clutch 168 and 169 respectively again with the upper belt pulley 156 and 157 of preceding driving belt 154 and back driving belt 155 engagements respectively, main shaft 170 is along the upper end longitudinal extension of transmission mechanism 142, two one-way clutch 168,169 rotations according to the importation, drive main shaft 170 along equidirectional rotation, rotate (from the back eyes front) for clockwise direction in this embodiment.Depress right-hand tread plate 139R, the right 154R of driving belt 154 rotates the belt pulley 156 that links with front clutch 168 along clockwise direction before the pulling, and this rotation is delivered to main shaft 170; When right-hand tread plate 139R moved downward, left-hand tread plate 139L 155 motions in the opposite direction of driving belt that move upward were then rotated back driving pulley 157 in the counterclockwise direction.Along with this anticlockwise motion, one-way clutch 169 idle running of back, like this, not clockwise rotating of main shaft 170 can be affected.When right-hand tread plate 139R reach its end of travel and left-hand tread plate 139L that the user will just have been risen when pressing down, the extension 164 of left-hand tread plate moves downward the right 155R of back driving belt, clockwise rotation is passed to back driving pulley 157, and main shaft 170 is clockwise rotated by back one-way clutch 169.As seen, each downward stroke of pedal 139R, 139L all drive shaft 170 rotate to same direction.

Main shaft 170 is by the supporting of the bearing in the transmission mechanism 142, and its front end extends to forward in the shaft coupling 173 from front column 144.Shaft coupling 173 comprises a bearing, and main shaft 170 can freely rotate in this bearing, so this shaft coupling does not transmit the rotation of main shaft.The back of adjacent shaft coupling 173, a main shaft 170 and a big belt pulley 174 link, belt pulley 174 drives a less relatively belt pulley 175 by driving belt 176, this belt pulley 175 drives jackshaft 177 again, relatively large belt pulley 178 is rotated, and belt pulley 178 drives a less belt pulley 179 again by belt 180.As special case of the present invention, belt pulley set 174,175 and 178,179 raising speed separately is 5: 1 than all, and but, this speed ratio can not be considered to limiting value.
