The specific embodiment

Fig. 1～3 expressions are according to the health and fitness facilities 10 of the present invention's first form.

This health and fitness facilities comprises elongate frame 12, and this framework is connected with seat 16, and the user can be sitting on the seat, and the backrest 18 that is used for user's back is located on the seat.For the purpose of storing and transporting, usually the seat 16 by one or more pole 20 supportings can fold downwards, make it be roughly parallel to framework, simultaneously in a similar fashion can be to the framework pivot so that take compact position by the backrest of one or more pole 22 supportings.Structure 24 can be used on the upper end of framework the holding device for use in the card of the information that is loaded with the body-building order.

This framework is bearing on the obliquity with respect to ground 26 by the U-shaped member 28 that suspends downwards, and this U-shaped member is connected on the support 32 of framework 12 rear sides at pivotal point 30 places.U-shaped member 28 can be inwardly towards framework 12 motions so that storage and transportation, or movablely as shown in Figure 1 leave framework so that provide maximum stable support for framework.

This health and fitness facilities comprises pedal 36 in base of frame.This pedal forms housing, and electric notor 38 and the air pump or the compressor that are driven and delivered air to by the cylinder 44 of framework 12 supportings by flexible pipe 42 by motor are positioned in the housing.

This health and fitness facilities comprises pedal 36 in the bottom of framework.This pedal forms housing, electric notor 38 and driven and be positioned in the housing by air pump or compressor that flexible pipe 42 delivers air to cylinder 44 by motor.Framework 12 forms the shallow cover 45 that has upper and lower relatively end 45B and 45C and opposing sidewalls 45D and 45D, and this cylinder is positioned at this cover, and is supported by this framework.This cylinder preferably is positioned in the cover fully, even make the part outside of this cylinder as seen also not stretch out from framework.

The upper surface 46 of pedal housing is zigzag or carries out roughening, and action face is provided, and location user's on the seat pin acts on this action face.

Flexible wire 50 extends on the main power source from motor, and is not shown.Switch 52 on the pedal 36 can activate so that motor 38 is connected on the main power source maybe with this power-off by user's pin.In this way, the operation of motor 38 can be controlled.Pressure relief valve 60 is connected on the cylinder 44 by flexible wires 62.Pressure relief valve also can be operated by user's pin.The user can open also pressurized cylinder 44 thus with compressor thus; Compressor cuts out, or reduce pressure in the cylinder by activated valve 60.

Cylinder 44 be connected on the piston 70 in case consist of the user provide resistance assembly 72.Its implementation method is described below.Cylinder 44 has the bottom 74 on the bearing part 76 that seals and be installed in belt wheel.Piston 70 has and is mounted in cylinder pistons reciprocating 78 and from the piston rod 80 of this extension.The upper end of bar is installed on the superposed belt wheel bearing part 82.

First pulley and cable system 84 are mounted to and act on down on the bearing part 76, and second pulley and cable system 86 are mounted to and act on the upper load-bearing body 82 simultaneously.System 84 comprises a pair of by hawser 90 interconnective handle 88A and the 88B on a series of pulley 92A～92E.Pulley 92C is by being connected on the bearing part 76 through pulley 100A on this bearing part and the hawser 98 on the 100B.The end of hawser 98 is connected on the anchor point 102 on the framework 12.

System 86 has the handle 108A and the 108B of the downside that is positioned at the framework by the hawser on pulley 112A～112E 110 respectively.Pulley 112C is by being connected on the bearing part 82 through being installed in pulley 116A on this supporting member and the hawser 114 on the 116B.

As can be seen from Figure 2 78 of piston heads act in the cylinder and guide in the volume.Therefore piston head forms a plurality of breach or otch 120, and the in-cylinder pressure on the first side of piston is identical with pressure on this opposite side.

Piston rod 80 is tubuloses, so its inside 122 is hollow.The upper end of connector 124 seal bar 80.Be connected the underpart opening of the bar on the piston head 78, and form and to make the opening 126 of hollow internal communication of the inside of cylinder 44 and bar.

Use when health and fitness facilities, framework 12 is positioned to make it to have orientation shown in Figure 1.The user can sit, kneel or stand when body-building.Suppose that the user will oneself be positioned on the seat 16 by its back backrest 18 that reclines.The user with he pin actuation switch 52 and motor 38 starts and then drive compression machine 40.In case when the inside of cylinder 44 had been pressurized to required air pressure, motor cut out.If hypertonia, pressure relief valve 60 activates and makes air discharge in cylinder.Therefore the user can use the control device 52 and 60 of pin operation relatively easily to adjust or the master cylinder internal pressure.

Suppose user's grasping upper handle 88A and 88B and handle is pulled down, shown in Fig. 3 arrow 130.Because pulley and cable system 84, following bearing part 76 risings and cylinder are along with the piston that enters by reciprocating motion in the cylinder raises.When bar 80 is forced into cylinder, produce the resistance that is tending towards moving shown in the reaction.The dischargeable capacity that is occupied by the forced air in cylinder and the hollow piston rod 80 reduces according to the degree that bar extends in the cylinder 44.

If cylinder 44 pressure inside are higher relatively, need sizable power moving lever 80 to enter cylinder so.But because compare the internal capacity of bar 80 with the volume of cylinder 44 relative less, when bar when moving in the cylinder more, the power that bar need be moved in the cylinder only increases slightly.In other words, on the haul distance that moves downward expression, by the only increase slightly of resistance of piston and cylinder component 72 expressions by handle 88A and 88B.

Because four times of the haul distance that the mechanical gain of system 84, the haul distance of handle 88A and 88B are pistons enters cylinder.Therefore compare with the haul distance of health and fitness facilities, but piston and cylinder component relative compact.Institute's attendant advantages is that when assembly is flexible owing to the movement degree of piston with respect to cylinder is restricted, the variation of in-cylinder pressure is restricted.

During the described stretching motion of assembly 72, the upper end of piston rod is by bearing part 82 supportings, and this bearing part is then by supporting member on the framework 12 or structure 140 supportings.On the other hand, when upwards drawing as grasping member 108A and 108B and with the direction of arrow 142, bottom 74 motions that upper load-bearing body 82 moves downward and prevents to be installed in down the cylinder 44 on the bearing part 76 by supporting relative with supporting member 140 on the framework or supporting member 146.

The haul distance that enters cylinder with piston is compared, and handle 108A demonstrates the relatively long haul distance identical with 88B with handle 88A with 108B.

Health and fitness facilities 10 has a plurality of significant advantages.At first, the user can adjust the pressure in the cylinder 44, even and this means that the user also can adjust resistance according to its physical qualification when the body-building.According to circumstances different, the user does not need to slip out of the hand and can adjust from handle 88 or 108.Secondly, as described, the haul distance that causes when using

handle

88 or 108 is four times of the piston haul distance that enters cylinder.This makes health and fitness facilities be of compact construction.

The 3rd, the quantity of the pulley in each system 84 and 86 is relative few, and this means that friction loss keeps very low.Therefore the active draft that shows by piston and cylinder component 72 (promptly when handle 88 move on the direction of arrow 130 or the power that produced when on the direction of arrow 142, move of handle 108) slightly greater than conduct when air Peng in the cylinder 44 bloated so that the negative resistance power of the power that produces when piston and cylinder component returned to its extended position.

Already mentioned another advantage needs piston rod further to enter cylinder when being in bar moves to cylinder power only increases slightly.This power is the function of in-cylinder pressure, and if this pressure enough high, the relative increase that moves to cylinder Nei Shili when piston is lower.The degree that power increases is the function of the cylinder 44 and the relative volume of hollow stem 80 inside.

This health and fitness facilities is in light weight.This resistance produces by using cylinder and piston component, this assembly by the user with air pressurized on adjustable selection and controlled level.This health and fitness facilities can be folded into flat relatively configuration compactly, can for example be stored under the bed when not using or behind the door.For this reason, seat and pedal fold into restoration position separately from its operating position, are stacked on the part separately of cover at seat on the restoration position and pedal.In this case, it is also therefore whole relevant with this health and fitness facilities to see that compressor and motor are installed in the housing 36.Shown in Fig. 1 curved arrow 158, housing can upwards fold into the restoration position near the compactness of framework when needing.Therefore this health and fitness facilities is crooked self-contained unit and only need be connected on the power supply so that operation.Yet, can adopt same principle that health and fitness facilities is set, this apparatus can be the compressor pressurizes by long-range installation in the lump of a plurality of like instrument.Pressure in each apparatus can be by each user's control separately if desired.

In each case, this control is the pin operation.But also can adopt hand operated, long-range driving or sound driver control device to adjust in-cylinder pressure.

The modification of Fig. 4～6 expression apparatuses 10.Use a plurality of elastic webbings 160 to replace piston and cylinder component 72.Wherein identical reference number is used for representing identical parts.

Fig. 4 represents that label is three bands of 160A, 160B and 160C, and this band is by on associated pulleys 162A, 162B and the 162C.The end of band terminates in round end 164A～164C respectively.

Band can adopt corresponding structure in its bottom.As shown in Figure 4, the bottom of band is by with around the pulley 162 similar pulleys 166.This bottom is connected on the plate 168.In each case, the stria 170 in the round end that respectively carries and the plate engages.

Plate 168 has the pulley 172 that is fixed on its rear side.Inextensible hawser 90 is by on the pulley 92 and terminate in handle 88, with shown in Figure 3 similar.Be apparent that pulley 172 is used for being equal to following bearing part 168 with pulley 92C identical functions and plate 168.When handle 88A and 88B pulled down, plate 168 moved upward and is with 160 to be subjected to tension force.The bottom of band moves upward, and the upper end that is fixed on simultaneously on the round end 164 keeps motionless.

In fact, the round end 164 of the upper end of band be fixed on similar with plate 168 and the plate 176 with the mode effect identical with upper load-bearing body 82 (see figure 6)s on.Be equal to hawser 10 and terminate in the hawser 178 of similar handle 108A of handle shown in Figure 3 and 108B by around the pulley of respective sets and act on the upper plate 176.If the power of upwards drawing is applied on the handle on the end that is fixed on hawser 178, plate 176 moves downward, and wherein lower plate 168 keeps motionless.

Health and fitness facilities according to Fig. 4～6 modification provides the double acting configuration, wherein can apply up or down pulling force or thrust, and wherein the mechanical gain of modification system is a selective value, normally 4: 1.Three bands are illustrated among Fig. 4.This quantity can change by the user, and the user can select one, two or three bring body-building.

The band that is positioned at rest position shown in Figure 4 is non-extensible relatively usually, and the resistance of stroke degree section start is low relatively.Guiding mechanism can be provided, and wherein one or more bands can be by around the intermediate pulley 180 and 182, shown in the illustration of Fig. 4.If separately pulley rotate thereon the axle between distance can adjust, can adjust belt tension so.This air pressure interior with changing piston shown in Figure 1 and cylinder component is equal to.

According to another form of the present invention, Fig. 7 schematically illustrates the resistance assembly 260 that is used for replacing resistance assembly 72 shown in Fig. 2 and 3 slightly.Resistance assembly 260 has a plurality of and similarity assembly 72, and wherein identical reference number is used for representing identical parts.Assembly 260 is not represented to be installed in the health and fitness facilities.It can the mode identical with assembly 72 use, shown in Fig. 1～3.

The main distinction between assembly 72 and the assembly 260 is that label in the assembly 260 is that the piston rod of 80A is an entity.As selection, if this bar is a hollow, the label of bar is that the bottom of 226A seals by plate or connector, makes it airtight.

The inside of cylinder 44 is as described by compressor or cylinder pressurization.

Piston head 78 also has breach or otch 120, and the in-cylinder pressure that this otch is guaranteed the piston head upside is identical with pressure on the downside of piston head.

When piston rod with respect to cylinder (wherein cylinder is motionless) if the motion or make cylinder move back and forth with respect to this piston rod (wherein piston rod is motionless), when bar 80A when entering into this cylinder more in the cylinder air further pressurize, and slight pressure reduces when bar is withdrawn from cylinder.The maximum volume that forced air occupies in assembly 72 equals the volume of cylinder and the summation of piston rod internal capacity and the volume that minimum volume equals cylinder and deducts the wall volume of piston rod, and this operation is roughly the same with resistance assembly 72.For assembly 260, the maximum volume that is occupied by forced air is slightly less than assembly 72 and equal the volume of cylinder.Minimum volume reduces equally slightly, and wherein this volume equals the volume that the cylinder volume deducts entity and packed-piston bar.But resistance assembly 260 provides the advantage identical with resistance assembly 72 basically.

Fig. 8 represents to be equal to equally another resistance assembly 266 of assembly 72.Assembly 266 comprises first or outer shell 268 and be positioned at second cylinder 270 of cylinder 268 inboards.Bottom 272 openings of cylinder 270 and by plate 274 supporting that wherein forms a plurality of holes 276.The upper end of cylinder 270 by with

cylinder

268 and 270 sealed engagement and comprise piston rod 284 extend through wherein the hole or plate 280 supporting of connector 282.The front end 286 of piston rod is loaded with piston head 288, and the inner surface 290 of this piston head and second cylinder 270 slides and sealed engagement.Outer or the upper end 292 of bar 284 engages with suitable structure 293 on the health and fitness facilities (not shown).Similarly, the bottom of cylinder 268 is connected on the suitable structure 295 of health and fitness facilities.Resistance assembly 266 can for example replace assembly 72 in mode shown in Figure 2.

Cylinder 268 and cylinder 270 pressurize simultaneously by the forced air from the compressor in the pedal (not shown).

Piston head 288 carries out and hollow stem 80 shown in Figure 2 or entity cylinder 80A identical functions shown in Figure 7, and when entering cylinder 270 with convenient piston head 288, the air in two cylinders is according to the air total amount pressurization by the piston head displacement of advancing.

Compare in the position of the prior art that the position that health and fitness facilities of the present invention raises should schematically illustrate with Fig. 9, Fig. 9 represents to use storage tank or the accumulator 300 from the air pressurized in the air source 302 of for example compressor.The independent resistance cylinders 304 that structure is relatively little is connected on this storage tank.Cylinder 304 comprises the piston rod 306 that has piston head 308, and this piston head is mounted to reciprocal and seal-moving in cylinder 304.From the prior art file, find out,, use the health and fitness facilities of prior art arrangement shown in Figure 8 very heavy owing to need at least two independent cylinders.If the configuration of prior art is adopted in health and fitness facilities, will be difficult to be provided at the compact exercise machine that is suitable for convenient transportation or storage under inactive storage pattern so.But this specific purpose realizes by health and fitness facilities of the present invention.

Adopt resistance assembly 72 and 260, the effective cross-sectional area of this piston rod to determine the air volume that this piston rod movement moves when interior to this cylinder.With reference to figure 2, suppose that the empty therein inside of this piston rod has area of section a, cylinder 44 has area of section A.When this bar moved in the cylinder distance 1, mobile air volume was provided by expression formula 1 * a.Because this area of section is significantly less than the area of section A of cylinder 44, the variation of in-cylinder pressure is relatively little, and this piston overcomes not along with the remarkable power that increases of the motion of piston rod is moved to the full extent.

In Fig. 7 embodiment, the area of section of solid piston rod 80A is a, and the distance that enters cylinder 44 when piston rod is when being 1, and mobile volume of air is a * 1, if the remarkable very big and situation that engage with cylinder 44 hermetically less than piston head 78 of this volume.

In Fig. 8 embodiment, the area of section of piston 288 is a, and the distance that enters cylinder 270 when piston is when being 1, and mobile volume of air is provided by expression formula a * 1.

In the embodiment that Fig. 1～3, Fig. 7 and 8 illustrate respectively, according to circumstances, if a is significantly less than the effective cross-sectional area of the area of section A or the cylinder 168 of cylinder 44, move to the position that it inserts cylinder fully from the position of cylinder withdrawal fully from it when piston so, resistance just limit increases.Although can adopt prior art arrangement shown in Figure 9 to realize the relatively little variation of air pressure, this need be a cost with at least one parts that occupy other space.

The ratio of A and a should be 6 but preferably higher at least.In this regard, between resistance that is produced during the piston stroke (this is the function of a and cylinder inner air pressure product) and change in resistance, must form compromise.

Figure 10 represents roughly and similar health and fitness facilities 400 shown in Fig. 1～3.But the upper end of framework 402 comprises the supporting member 404 that extends on the front side (be framework towards a last side) from this frame part.This supporting member comprises that two its ends are connected on the cross bar 410 and are pivoted on bar 406 and 408 on the supporting member 140 at the opposed end place.Cancellation handle 88A and 88B, and extend to the end of the hawser 90 on this handle but be connected on the lateral rod 412.Hawser is by on the pulley on the cross bar 414, and the structure on the cross bar guarantees that hawser remains in the pulley reliably.If do not use cross bar 412, can keep handle 88A and 88B so, and user's arm will be not limited to operation simultaneously.
