Description

Treadmill with lifting folding device

Technical field

The utility model relates to a kind of treadmill with lifting folding device.Especially refer to a kind of treadmill that reduces the running platform height.

Background technology

The running desk of common treadmill is for runner's use of running, for making the runner that better running effect be arranged, how can design this running platform front end liftable, increase movement effects with the gradient that changes running platform, but under safety is considered, treadmill now requires the terrain clearance of this running platform can not be too high more, causes danger avoiding.

Accompanying drawing 6 and accompanying drawing 7 are a kind of treadmill schematic diagrames in the prior art, the figure illustrates the high-low regulating of treadmill running framework, it mainly lies in two and links on the sheet 4, respectively according to high, low and front and back position and be provided with a framework pivot hole 41, one front strut pivot hole, 42 and one long shaft-pivot hole 43, wherein, framework pivot hole and front strut pivot hole system lay respectively at the front end of binding sheet and the place, higher position of central authorities, the position of long shaft-pivot hole then is located at and is linked sheet rear end and lower position, therefore, the convenient front end both sides that are hubbed at running framework 5 with framework pivot hole respectively of this binding sheet, multiple utilize front strut pivot hole again and be pivoted with front strut 51 and combine, afterwards, in the long shaft-pivot hole of two binding sheets, place a long shaft rod 431 again, a guiding mechanism 6 at last again is pivoted on long shaft rod, and make the manipulation end of this complete machine structure that withers cross out, and be located on the spacer 511 of front strut to the front end of running framework; So, that utilizes guiding mechanism controls part when making its pulling screw rod 61 displacement forward or backward, drawing long shaft rod synchronous shift thereupon, at this moment, linking sheet will serve as that axle produces the effect of moving of revolving with the position in front strut pivot hole, and then the running framework is moved with the high and low accent of framework pivot hole site and change it and prop up angle, should the running framework with lifting.

Because this running framework system links sheet with two and this front strut articulates, and with the pulling screw rod of this guiding mechanism is flexible should the running framework with lifting, weight of therefore should the running framework being carried and the strength system that produces when running link sheets by two and are born, two link the strength that sheet bore is then supported by the pulling screw rod of this guiding mechanism, this pulling screw rod system extends the longest when minimum when the running framework is reduced to, can on the pulling screw rod, produce bending stress, and cause the wearing and tearing of this pulling screw rod, cause the telescopic moving smoothly of pulling screw rod.Though the pulling screw rod of this guiding mechanism is arranged with an external member 62 in 511 of two spacers, can appropriateness slow down the stressed of pulling screw rod, but the bending stress for this pulling screw rod does not still have too big help, and this external member even can interfere with the rotation of this pulling screw rod.

Moreover, because this running framework system is a lifting with the front strut pivot hole that links sheet, and for making this running framework front end be increased to certain altitude, therefore the front strut pivot hole of this binding sheet and the distance between framework pivot hole need have a length, can cause the front strut pivot hole and the arm of force LI between framework pivot hole that produce this binding sheet long thus, when the running framework serves as when axially going up the pivot folding with this framework pivot hole, and long arm of force LI can increase front strut pivot hole stressed of this binding sheet, make the support force after this running framework folding not good, the running framework after can't the firm support folding.

Remove this, because this two end that links sheet extends a length downwards, be positioned at the lower position of binding sheet for long shaft-pivot hole, and be to put the space in response to two pivots that link sheet, make an overhead segment distance H1 of this running framework, and cause the running framework too high, the height of this running framework is high more, the center of gravity of runner when running also can be high more, and allow the runner produce fear, unsafe sensation easily.

Accompanying drawing 8 and accompanying drawing 9 are the another kind of treadmill schematic diagrames in the prior art, the figure illustrates the design of the inclination angle adjusting structure of treadmill, it mainly is to include one to connect the drive unit 71 that is hubbed at treadmill running platform 7, and be pivoted the simultaneously running platform that is connected to treadmill and the drivening piece 8 of vertical type shelf 72, this drivening piece includes the two drive arms 81 of being located at the running platform both sides respectively, each middle system that drives arm is hubbed at the vertical type shelf that is connected to this treadmill respectively, and an end 811 that respectively drives arm is to extend the both sides that are articulated in running platform forward, each 812 of other end that drive arm extends back and connects jointly an armite 82 is set, and one be arranged between drive unit and drivening piece, and can drive the transmission mechanism 9 that drivening piece rotates relative to the vertical type shelf of treadmill.

Because the running desk of this treadmill drives arm by two of drivening piece and drives lifting, respectively should drive arm system articulates with centre position and this vertical type shelf, and respectively should drive arm forward, after the two ends of extending respectively then be articulated in running platform and transmission mechanism, promote an end 812 of this drive arm forward by transmission mechanism, making the other end 811 that drives arm is the axle center pivot pendulum that makes progress to articulate the vertical type shelf place, and the lifting of drive running platform, therefore, this running platform is the pivot pendulum space and the distance of the end 812 that is connected with transmission mechanism in response to this drive arm, and the ground clearance H2 of this running platform can't be reduced, it can cause equally and allow the runner produce fear, unsafe sensation.

Moreover, because of this drives the two ends 811 that arm 81 articulates running platform and transmission mechanism, 812 is to extend to different directions respectively, and should drive an arm and an end 811 that articulates running platform, system is the axle center to drive arm centre position and vertical type shelf articulated section, and the pivot pendulum is to drive the running platform lifting, the strength that transmits when therefore running platform is run can be born with an end 811 that articulates running platform by driving arm, make this drive arm stressed excessive, drive the stressed of arm if will slow down, and reduction is when driving the length of arm one end 811, can influence the height that rises of running platform again, because drive arm and an end 811 that articulates running platform to and the vertical type shelf articulated section between length system determine the height that this running platform rises, so the height that the running platform of this treadmill rises can be restricted, the angle that running platform is risen changes little.

Therefore, the running platform lifting structure of the treadmill in the aforesaid prior art causes the stressed defective such as excessive of the too high and lift component of running platform terrain clearance, is then improved part for the utility model.
