In a specific embodiment of body-building device, resistance element 76 extends between each pedal assembly 12 and framework 14, with the anterior of sustain pedal assembly and suppress the downward motion of each pedal.These one or more resistance elements can be arranged on the diverse location between footrest frame and the main frame.In Fig. 1-7 and other embodiment shown in the drawings, resistance element comprises the one 108 and the 2 110 damper.Damper stops and suppresses the motion of pedal.More particularly, first or left side damper 108 between the upright frame element 40 in the left side of left pedal assembly or lateral frame element 54 and left side, extend.Second damper 110 extends between the upright frame element 42 in the right side of right-side pedal assembly or lateral frame element 56 and right side.In alternate embodiments, damper is at the lateral frame element of each pedal assembly and extend between the part below the pedal assembly.In another selectable example, damper can be connected to the pedal front portion between inboard and outside footrest frame element.

In a particular embodiment, damper (108,110) is fluid type or air type damping unit, and not internally or outside unite with returning spring.Same, when user's pin is climbed up pedal when anterior, damper is subdued and is suppressed the downward power of step, so that provide buffering for user's pin, leg and different leg joints (as ankle and knee).In some constructions, drag devices also is adjustable as and reduces or increase the downward haul distance of pedal.Can be for damper provide the user the adjustable damping collar, it can make the damping force of damper increase or reduce to cooperate any specific user's needs when rotating.The specific damper that can be used for body-building device of the present invention is also explanation shown in the US 5762587 of " fitness machine that has adjustable resistance, hydraulic cylinder " in denomination of invention, and its content is included in this as a reference.

Usually, damper comprises a cylinder that is filled with hydraulic fluid.Piston rod stretches out in cylinder.In cylinder, piston is connected with piston rod.Piston defines the hole that at least one hydraulic fluid can flow through and comprises a detection valve.Piston is divided into two fluid-filled chambers with cylinder.In the damper start-up course, piston in cylinder or upwards or move down.Damper move downward or the process of extending in, fluid flows through this hole with certain speed, the control of the quantity that is subjected to the hole of this speed part and the size in hole.Damper move upward or the process compressed in, fluid flows through the detection valve.The collar is exercisable to be connected on the plate of uniting with this or a plurality of hole.The rotation of the collar will be exposed or be covered the hole that is used for fluid flow, reduce or increase the damping force of damper thus.Alternatively, the resistance collar is connected with tapered plunger, and plunger is introduced in the hole between the hydraulic pressure chamber of damper.The degree of depth of plunger is with the resistance of the control damper of part.Preferably, remove returning spring shown in Figure 4 in ' 587 patents.

The denomination of invention that another specific damper that can be used for body-building device of the present invention was submitted on April 22nd, 1997 is also explanation shown in the US 5622527 of " stepper of independent operating ", and its content is included in this as a reference.This damper can be with ' spring 252 shown in Figure 10 uses in 527.After they were pushed downwards, spring provided a pedal or make the restoring force of its answer of moving up.Same, in one embodiment of the invention, damper only provides resistance, but restoring force is not provided.In an embodiment who does not adopt spring, damper can be set to provide one at 47kgF to the resistance between the 103KgF.Interchangeable resistance element will be further described hereinafter.

Figure 10-the 14th, the partial isometric view of body-building device has shown pedal interconnect structure 78 especially.Among Figure 10-14 each has all shown this interconnection structure that is in different positions.Figure 15 is the side view of the pedal interconnect structure identical with locations of structures shown in Figure 12.(A, B)-20 (A B) is isometric view with the corresponding body-building device of view shown in Figure 10-14 to Figure 16.In the specific embodiment of the interconnection structure shown in Figure 10-15 and other view, interconnection structure comprises a rotating rocking bar or " swing " arm component 112 that is supported on the rocking bar lateral direction element 114, and the rocking bar lateral direction element extends between the left side 32 of framework and right 34 side element.Rocker arm assembly is exercisable to be connected with each pedal assembly 12.Illustrate the most clearly as Figure 15, the rocking bar lateral direction element defines a U-shaped cross-section.Each upstanding portion of this U-shaped element defines a keyway 116.The top of keyway defines a rotation hole 118.Rocking arm comprises a rocking bar or interconnection turning cylinder 120, and turning cylinder is supported in the rotation hole and between each rotation hole and extends with the rotational support rocking arm.As hereinafter described in detail, keyway provides a groove that can move for interconnection structure between " transporting " position and " use " position.

The left and right sides Outboard Sections of rocking arm comprise respectively first or the lower-left side rotate pin 122 and second or the lower right side rotate pin 124.The support 126 that roughly L shaped support first upside rotates pin 128 stretches out from inboard or the right side element 56 of left pedal 12A, makes upside rotate pin and is supported in the mode that is parallel to medial element, is positioned at its underpart and the outside usually.Second support 132 that roughly L shaped support second upside rotates pin 130 extends downwards from inboard or the left side pipe 54 of right-side pedal 12B, makes upside rotate pin and is supported in the mode that is parallel to medial element, is positioned at its underpart and the outside usually.

First bar 134 is connected the upper left side and rotates between pin 128 and the lower-left side rotation pin 122.Second bar 136 is connected the upper right side and rotates between pin 130 and the lower right side rotation pin 124.Bar is connected to pedal on the rocking arm.In a particular embodiment, each bar (134,136) defines the thread of an adjustable-length.The thread utilization is rotated pin up and down and is connected in ball connection 138 structures.Thread defines upper and lower screw shell 140.Each screw shell defines a toroidal cavity that has the opposite end to support a rotating sphere.This rotation pin is supported in the rotating sphere.Bar defines the end of thread 142 in the relative screw shell that is supported on correspondence.

As what hereinafter will go through, lockable pedal assembly 12 is not so that rotate around rear axle 16.When locking, pedal assembly common provide effective single-minded nonrotational type a mark time surface similar with 18 to treadmill.In the body-building device assembling process or thereafter, by the length that one or two threads 134,136 are regulated in the rotation of bar 142, the height of two pedals can accurately align, and makes two pedal bands that the parallel surface of marking time of latched position is provided together.

Interconnection structure 78 (for example rocker arm assembly) couples together left pedal and right-side pedal in such a way, promptly when a pedal (for example left pedal) when back turning cylinder 16 then upwards rotates downwards, another pedal (for example right-side pedal) upwards then rotates respectively around the back pivot center of cooperation.Thus, two pedals interconnect in such a way, and a kind of step motion promptly is provided, and the downward motion of pedal is accompanied by the motion that another pedal makes progress, vice versaad.In such step motion process, no matter be to make up separately or with the motion of marking time, rocking arm 112 rotates or swing around rocking bar axis 120.

(A, B)-20 (A B), will be further described the similar motion of climbing the mountain that motion provided by body-building device 10 referring now to Figure 10-14 and 16.Representative user towards preceding use (after this being called " user ") has been shown in Figure 16 B-20B.Walking before user's forward, the device type that is configured to climb the mountain is used, and promptly pedal moves back and forth.A user is only represented in illustrated step motion.In some applications, pedal 12 may not move between the highest and extreme lower position, but between the position between them.In an application, the user may have than illustrated weak point or long stride.Some should in, the user may walk backward, perhaps towards the rear, perhaps towards the rear and backward walking.

In Figure 10 and 16A, left pedal 12A is in lower position, and right-side pedal is in the higher position.With reference to Figure 10 and 14, the left side of rocking arm 112 rotates, and upwards rotate on the right side of rocking arm.In Figure 16 B, illustrated user's right crus of diaphragm just forward and be in the front portion of right-side pedal band.On the orientation of the user shown in Figure 16 B, in the preceding type of climbing the mountain application process, user's left leg will extend back downwards, and the major part of user's weight drops on the left pedal.User's right leg is crooked and extend back in knee, makes user's right crus of diaphragm begin to be pressed on the right-side pedal downwards.From the orientation shown in Figure 16 B, the user is converted to balance between the leg of the left and right sides with his body weight, and begins to utilize his right leg to impel right-side pedal downward to pressing down.Because the motion of band, two pin all will move backward from the position shown in Figure 16 B.

Figure 11,17A and 17B show is to install 10 and user's orientation after the position shown in Figure 10,16A and the 16B.The downward pressurized of right-side pedal 12B by rocking bar interconnection structure 78, makes that left pedal 12A begins to rise.User's right crus of diaphragm begins from the position shown in Figure 16 B backward and moves down.User's left foot from the position shown in Figure 16 B backward and move up.

Figure 12,18A and 18B show is to be in the right-side pedal 12B midway of upward stroke and to be in left pedal 12A midway to down stroke.Equally, pedal assembly is in basic identical height place, framework 14 tops, and endless belt 18 also is in equal height.Shown in Figure 18 B, user's right crus of diaphragm and leg move down backward from the position shown in Figure 17 B.User's left foot moves up backward from the position shown in Figure 16 B.Begin when in this, the user marks time forward to trample to be with to lift left foot from the left side; Promoting left side heel and user thus turns on the ball of foot of left foot.Usually, left pedal will be born more weight than right-side pedal now.

After the orientation shown in Figure 12,18A and the 18B, right-side pedal 12B continues its downward motion, and left pedal 12A continues motion that it makes progress until the orientation of Figure 13,19A and 19B shown device.In Figure 13,19A and 19B, left pedal is than right-side pedal height, and rocking arm 112 rotates around rocking arm pivot center 120 and makes its right side be lower than its left side.In this position, user's right leg continues backward and moves down.The user leaves left pedal with left leg lifting and moves forward.At the upper position of left pedal, the user tramples his left foot in the forward position of trampling band downwards.The all weight of user is applied on the right-side pedal and up to the user his left foot is placed on the left pedal.The user continues a downward power is provided on right-side pedal, impels left pedal to rise.

Figure 14,20A and 20B have shown and approximately have been in the right-side pedal 12B of extreme lower position, and shown the left pedal 12A that approximately is in the extreme higher position.In this, the user tramples the front portion 22 in left pedal downwards, and begins to utilize left leg to press down.The user begins to promote right leg simultaneously.Power downward on the left pedal will be delivered to right-side pedal by interconnection structure 78, impel right-side pedal to begin to rise.

(A, B)-20 (A B) has represented the reciprocating half cycles of pedal to Figure 16, i.e. the motion of left pedal from the motion of lower position to a higher position and right-side pedal from higher position to a lower position.The complete type of climbing the mountain a body-building circulation is begun from certain position to replying the motion representative that same position finishes by a pedal, its in such a way, promptly comprise upward stroke (from the lower position to the higher position) that pedal is complete and pedal complete to down stroke (from the higher position to the lower position).For example, with the lower position (higher position of right-side pedal) of left pedal be the circulation of marking time of reference point will comprise left pedal from the lower position to the higher position upwards and the motion that turns back to its lower position downwards.In another example, with the intermediate point position (referring to Figure 18) of left pedal is that the circulation of marking time of reference point will comprise the motion that make progress of pedal to the higher position, downward motion from process intermediate point position, higher position to lower position, and the motion that makes progress that turns back to the intermediate point position.Irrelevant with the order that pedal moves up and down.Thus, the motion that makes progress is downward motion subsequently, and perhaps downward motion is motion upwards subsequently.

With reference to Figure 10 and other view, in a structure, this body-building device comprises a pedal sensor 144, and it provides with the each downward stroke of each pedal and exports pulse accordingly.This pedal sensor comes executable operations by second snap switch 146 that comprises a magnet 148 and a pick-up 150.Magnet is connected to from the end of rocking arm 112 upwardly extending supports 152.Adjust the magnet orientation and make it through the pick-up swing, pick-up is installed on the support 157 and links to each other with rocking bar lateral direction element 114.Spring was opened 146 passes and is triggered an output pulse when magnet 148 was through pick-ups 150 at every turn.Thus, when moving down, right-side pedal 12B (passes through the motion of pick-up downwards corresponding to magnet), snap switch transmits an output pulse, and when left pedal 12A moves up (corresponding to the upwards motion of process pick-up of magnet), snap switch also transmits an output pulse.This output pulse is used for monitoring that use moves up and down along with pedal and the swing and the number of strokes may of the pedal that produces.Utilize the additional sensor of perpendicular setting, can also determine the vertical dimension of the degree of depth or stroke.This output pulse is used from separately or in tape speed signal one provides the body-building frequency to show, and can be used in the various calculating relevant with body-building, for example definite user's calorie depletion rate.

As Fig. 3,6 and 16A-20 illustrate the most clearly, In a particular embodiment, each pedal comprises a bottom outside assembly 154.This bottom outside assembly comprises the inboard that is connected footrest frame and the support between the lateral element 156 that are essentially V-arrangement.The apex region directed downwards of V-shaped rest also limits a flat installation surface 158 usually.Block 160 is fixed to be installed on the prone part in surperficial bottom.When body-building device is installed, preferably pedal is set by thread (134,136), make when pedal is in its extreme lower position block 160 be held in place in the locking lateral direction element 162 of below slightly above.If pedal reduces as far as possible, buffer 164 can be fixed on the lateral direction element 162 with the buffering pedal.In an example, block is by hard, inflexible, plastics manufacturing.This block can adopt solid or elastomeric polymer material to make.If in use block is reduced on the locking lateral direction element, the block of elasticity form will provide some to cushion the buffering that is provided by buffer to be provided, buffering perhaps is provided when not using buffer.

As mentioned above, this body-building device 10 can be configured in " locking " position, does not rotate up and down at this position upper footboard assembly.In a particular lock orientation, the pedal assembly twist-lock makes that trample band is parallel to each other, and is about 10% the gradient with respect to the rear portion of body-building device.Therefore, in preceding use, the user can simulate to mark time and ascend a height, and the user can simulate the descending of marking time in using towards the back.
