The platen sprung parts can also comprise the resilient suspension sleeve or the band of a softness.In an example, the diameter of sleeve is slightly less than the platen plate supporting part.For sleeve being fixed on the platen plate supporting part, sleeve extend past platen plate supporting part also passes through the restraint fix in position of sleeve.Sleeve can adopt any width, so that it can only be arranged along the part of platen plate supporting part or along the whole length of platen plate supporting part.The platen plate supporting part also has a circumferential groove or otch, so that laterally keep hanging sleeve.As selectable scheme, replace sprung parts, the platen plate supporting part can comprise hard (incompressible) parts that are positioned on the platen plate supporting part.

The rear portion of each pedal assembly (12,14) all is rotatably supported in the rear portion of framework, so that each pedal assembly all can rotate up and down.The front portion of each pedal assembly is bearing on the framework by one or more dampings or " resistance " part, cross tie part or their sub-assembly.According to structure, but the pedal assembly independent rotation, or relatively rotate with respect to each other (that is, one is upwards rotated, and other parts rotate).

Figure 22 is along the cutaway view shown in the line 22-22 among Fig. 4.Figure 23 is the amplification partial sectional view of Figure 22.Referring to Fig. 7,11,22,23 and other view, each pedal assembly (12,14) all is rotatably supported near the frame rear portion.In a kind of specified scheme, the rear axle bearing assembly 60 on left side and right side be arranged on each corresponding pedal assembly and be generally body-building device left back and right back place or near.Side shaft 102 behind the back side shaft bearing assembly rotatably support (in a kind of scheme, being the common pivot axis of pedal).Back side shaft extends between the bearing assembly of the left and right sides and rotatably support left and right sides pedal assembly.Back side shaft can be the assembly of continuous member or different parts.

Referring to Figure 11, at the rear portion of body-building device, sleeve 104 extends internally from the top surface of each side plate (30,32) at device rear portion especially.Back side shaft bearing assembly is fixed on each corresponding support.Each rear axle supporting member 60 includes the lower bearing supporting member 106 of a pair of lateral offset and the upper bearing supporting member 108 of a pair of corresponding lateral offset.Bottom and upper bearing supporting member have semi circular features respectively, and they cooperatively interact to be defined for the circular port of supporting radial ball bearing assembly 110.The end of back side shaft is rotatably supported in the side shaft bearing assembly of corresponding back.Each back side shaft bearing assembly includes two radial ball bearings 110 spaced apart from each other.As being clear that in Figure 22 and 23, each end regions of back side shaft is by the radial ball bearing rotatably support of a pair of lateral offset.

Referring to Figure 22,23 and Figure 24 (decomposition view of back roll assembly), back roller 24 about back roll assembly 112 comprises.As shown in the figure, back roll assembly has two different belt land surface (left roller and right roller); Yet roll assembly manifests single continuous outer surface.Can have the single rear roller that has single axle, a pair of differential roller on single axle or paired axle.In addition, can have the common axis between roller and pedal, perhaps have the different axis between roller and pedal.For example, pedal can rotate around a line that is positioned at roll shaft the place ahead, the place ahead and below etc.

Each back roller segment includes one and is rotatably supported in external cylindrical parts 114 on the back side shaft 102 by inboard and outboard bearing (116,118).Each pedal assembly trample belt all with corresponding external cylindrical components bonding.In a kind of scheme, each cylindrical parts all is limited with an exterior contour that protrudes slightly, and, the summit of projection along circumferential arrangement near the mid point of cylindrical parts.The shape of protruding helps to remain on the center of roller afterwards with trampling belt.In a specific scheme, the external cylindrical parts have the radial dimension that the longitudinal center from outer ledge towards outside cylindrical parts increases.The radial dimension of this increase can maybe can be to go forward one by one uniformly, so that the radial dimension that increases and be the essentially identical radial dimension at center with the mid point of outside cylindrical parts.Alternatively, external cylindrical parts 114 can limit uniform radial dimension along columniform length direction.

Protuberance or protrusion shape (preliminary roller of protuberance also can be provided) except the back roller, in a kind of scheme of the present invention, comprise that belt guiding device 118 is (referring to Figure 10,25,27 and other view), it is fixed on the platen that is positioned at roll assembly 112 the place aheads, back just, to help to keep the aligning of belt 18.The belt guiding device has the surface that reduces gradually or tilt that engages with the outer ledge of trampling belt.The leap of human body mainly has the longitudinal force component that can produce forward thrust during crossing over.Yet most of people also have outside or cross force component slightly during crossing over.This cross force component acts on the belt, thereby makes belt produce dislocation.Particularly, on the roller of back, force the rear portion of belt outwards to be moved.Therefore, the belt guiding device is positioned on the pedal to engage with the rear surface, the outside of trampling belt.The interaction of the belt guiding device on the belt helps to keep belt accurately alignment between roller, to offset most of users' horizontal leap power.

Referring to Figure 22,23 and 24, in a kind of specified scheme, the back roll assembly of back side shaft 102 each pedal assembly of supporting.Therefore, back roller about also as the public rear portion axis rotatably support of the public rear side pivot center of pedal.In a kind of certain party, back side shaft 102 has first (left side) part 120 and second (right side) part 122.Each rear side shaft portion includes axostylus axostyle, and stretch out and by corresponding axle bearing assembly 60 supportings from relevant roller the outer end of axle.Combine by sleeve 120 (being also referred to as " collar " herein) the inner each shaft portion.The outside cylinder of oppressing each roller passes sleeve, thereby exterior cylindrical is mutually combined (and roller is mutually combined), so that they can rotate synchronously.Sleeve is by radial ball bearing 118 rotatably supports at the place, the inner of each part that is arranged in pairs in the back side shaft.The outer end of each roller also by with corresponding axle bearing assembly near radial ball bearing 116 supportings.Therefore, each roller is rotatably supported on the side shaft of back by the radial ball bearing towards each side location of roller.In addition, by sleeve, roller rotates together around the rear side axis.

If realize integratedly by sleeve 124, the roll assembly that then is rotatably supported on the shaft portion (120,124) provides the structural rigidity supporting along the back of two pedal assemblies (12,14).Particularly, roller and sleeve are rotatably supported on the rear side axostylus axostyle by four radial ball bearings (116,118).Therefore, roller is connected rotationally with the back side shaft.In addition, each outer end portion of each part of back side shaft all is bearing in each bearing assembly 60 by pair of bearings 110.The similar device that roll assembly can avoid adopting certain type axle supporting bracket or the length direction of edge axle combines with framework between the end.

In use, when each pedal rotated, corresponding shaft portion (120,122) also rotated.Yet shaft portion rotates in the opposite direction; Therefore, when a part clockwise direction rotated, another part then rotated counterclockwise, otherwise too.By the structure of roll assembly and shaft portion, when roller rotated together, axle can rotate along opposite direction.Sleeve provides the connection between the roller, has supported the rear side shaft portion simultaneously so that the in fact back side shaft of one is provided.

As mentioned above, footrest frame part in the outside rotates around identical axle 102 as roller.Referring to Figure 22, make outside footrest frame part 54 continuous with the back side shaft between the outer bearing bearing assembly (106,108) that is positioned at corresponding bearing assembly 60.Shaft portion (120,122) is fixed on the corresponding outside footrest frame part 54.Axle stretches out from outside footrest frame part.Outward extending shaft portion is bearing in the outboard bearing bearing assembly.In addition, bar extends internally from outside footrest frame part.The shaft portion that extends internally is bearing in the inboard bearing bearing assembly.The radial ball bearing of rear support assembly side shaft behind the rotatably support on respect to two positions of any side of outside parts.The part that extends internally of corresponding shaft portion also supports corresponding roller.Therefore, pedal can rotate up and down around the back side shaft, and roller can rotate around the axis.

In order to keep suitable tolerance, can be with three parts (that is, cylindrical central sleeve part 124 and two outside roller segments 114) working roll.In order to assemble roller, internal bearings 118 is pressed in the mid portion, then left and right sides Outboard Sections is depressed on the core.In order to finish the assembling of roller, outboard bearing 116 is pressed in the support of bearing 126, then be pressed in the end of Outboard Sections.Do not comprise retainer among some embodiment.Though roller can be made by integral piece, its process time and cost all may be higher than the three-member type assembly.

The three-member type roll assembly can provide some attendant advantages.At first, back roll assembly provides a supposition axle, thereby allows shaft portion also to support the roll assembly that rotates along a direction simultaneously with the pedal assembly independent rotation.As institute hereinafter in greater detail, CD-ROM drive motor is fixed to by belt on the drive pulley 128 that directly links to each other with roll assembly, with the driving belt of walking.Secondly, back roll assembly is resisted the tensioning and the moment of torsion of the belt that is produced by the user as a mechanism in the mechanism.This is a reason of outer bearing in installing in the roller of back.The contact point of bearing can form in order to bear the long lever arm of power above-mentioned.Bearing is installed on the axostylus axostyle that is welded on the above-mentioned pedal arm.Back roller freely rotates around axostylus axostyle.
