See also Fig. 1, shown in Figure 2, the utility model treadmill 1 comprises a frame main body 10, one running grillage 20, a running board transmission group 30 and an elevating folding mechanism 40, mainly ordering about this running grillage 20 by this elevating folding mechanism 40 does lifting or folding action, and can meet user's user demand, wherein:

This frame main body 10 is to be upright attitude, has a  shape and holds up bar 11 and two relative runners 12, and this  shape holds up bar 11 to be provided with a

control display board

13, and 12 of this two runners are provided with a holder 14, and its two relative medial surface also offers a slide rail 121 in addition respectively again.

This running grillage 20 is to be located between two runners 12, at least comprising a running board 21 and runs and to be with 22, make this running be with 22 covers to be overlying on this running board 21 outer rims, its back of the body edge appropriate location has been horizontally set with a fixed axis 23 in addition in addition, and the rear end can be provided with movable pulley 24, and front end two side faces book office then is drilled with a pivot hole 25 respectively.

This running band transmission group 30 is to be used to order about this running be with 22 to take turns commentaries on classics, be located at this running grillage 20 forward and backward two ends respectively, at least formed with counter drive shaft 34 by a main motor 31, a belt pulley 32 and a final drive shaft 33, mainly by this main this belt pulley 32 of motor 31 transmissions, make this belt pulley 32 drive this final drive shaft 34 rotations, this final drive shaft 33 then cooperation is located at counter drive shaft 34 transmissions of these running grillage 20 rear ends, makes this running be with 22 to be the circulation wheel and to change.

This elevating folding mechanism 40 is located on the holder 14 of this frame main body 10, comprise a servo motor 42 and gear-box 43 that is used to make a drive screw 41 rotations, and driven by this drive screw 41, and the slippage action is made a sliding axle 44 and two lifting poles, 45, the two folding support 46 and two travel(l)ing rests 47 of lifting and jackknife action to order about this running grillage 20 before and after doing, wherein:

This drive screw 41 is to wear the screw 441 on this sliding axle 44 and articulate with this sliding axle 44 in the mode of being spirally connected;

These sliding axle 44 2 ends are respectively equipped with a pulley 48, should and pulley 48 is slide rail 121 places that place this frame main body 10 respectively, and in addition can supply these two liftings pole, 45 1 end pivot covers on this sliding axle 44, and make the pivot of holding in addition of this two liftings pole 45 be placed in fixed axis 23 appropriate locations on this running grillage 20;

Respectively this folding rack 46 is to be hubbed at respectively these runners 12 front end appropriate locations simultaneously with travel(l)ing rest 47 1 ends, only respectively these folding rack 46 other ends are to be hubbed at this running grillage 20 side appropriate locations with solid form, and this travel(l)ing rest 47 is held the pivot hole 25 that utilizes a stretching latch fitting 49 to insert on these running grillages 20 in addition, and being the solid form of the movable pivot that stretches, this stretching latch fitting 47 is made up of a hinged arm 491 sheathed elastic component (not shown).

In view of the above, drive drive screw 41 by this servo motor 42 and rotate, move forward and backward with these slide rail 121 places, use making this running grillage 20 can produce relative lifting action, make this running grillage 20 be an angle and tilt (as shown in Figure 3) to order about this sliding axle 44; When if this travel(l)ing rest 47 holds pivot to be fixed in 25 places, pivot hole of this running grillage 20 in addition, the front and back slippage of this sliding axle 44 can make this running grillage 20 produce relative jackknife action (as shown in Figure 4).

Please consult Fig. 3, shown in Figure 4 again, when the utility model uses, running grillage 20 utilizes sliding axle 44 directly to promote and does the action of lifting, and when its desire is used folder function, then utilize stretching latch fitting 49 that running grillage 20 is one in frame main body 10 lockings, make when sliding axle 44 promotes running grillage 20 that 20 meetings of running grillage are that jackknife action is made in the pivot axle center with the end that travel(l)ing rest 47 is fixed in frame main body 10.

Grillage 20 produces malfunction in lifting or folding process in order to prevent to run, therefore, supply solid 25 places, pivot hole of these travel(l)ing rest 47 pivots on this running grillage 20, other is provided with an electronic induction switch 26, and this electronic induction switch 26 is communicated with the power system (not shown) of this main motor, when this electronic induction switch 26 of mat is touched by this stretching latch fitting 47, can cut off main motor 31 power supplys immediately.

Moreover, in these running grillage 20 dual side-edge appropriate positions, other is provided with a limit switch 27 that is communicated with this servo motor power supply circuit (not shown), this limit switch 27 can be in contact with it when this folding rack 46 increases to predetermined altitude, maximum elevation when limiting these running grillage 20 liftings, ideal as for this limit switch 27 is provided with position and utilization principle thereof, mainly be because of when running grillage 20 in carrying out elevating folding when action, because folding pole 46 all belongs to fixing inconvenience with the angular relationship of 20 of running grillages and (please cooperate and consult Fig. 1, shown in Figure 4), and when running grillage 20 in carrying out height lift adjustment when action, this folding pole 46 then has very with the angle of 20 of running grillages, and obvious variation (please cooperate and consult Fig. 1, shown in Figure 3), therefore, angle by this folding rack 46 changes, and is set the maximum elevation of running grillage 20 liftings.

In addition, please referring again to Fig. 5, shown in Figure 6, wherein shown in Figure 5 is the of the present utility model second preferable combination form embodiment, its is characterised in that different with first most preferred embodiment: respectively these travel(l)ing rest 47 1 ends of this elevating folding mechanism 40 are solid and these frame main body 10 appropriate locations of direct pivot, and need not utilize stretching latch fitting 49 pivots solid, when using this sliding axle 44 and doing forward and backward displacement, only can relatedly make this running grillage 20 produce relative jackknife action.

And shown in Figure 6 be the utility model the 3rd preferred embodiment, itself and first, second most preferred embodiment is different to be characterised in that: this sliding axle 44 is to utilize two buffer bars 52 to be connected with a power transmission shaft 51 to be pivoted, wherein, the appropriate location is equipped with a transmission screw 511 on this power transmission shaft 51, then provided a through hole 411 on this sliding axle 44, mainly make this drive screw 44 wear this transmission screw 511 and this through hole 411 respectively, when using these drive screw 44 rotations, this power transmission shaft 51 can produce the action that this sliding axle 44 of ejection moves forward and backward, do lifting or folding to order about this running grillage 20, simultaneously, setting by this buffer bar 52, can reduce by 20 liftings of running grillage or produce vibrations when folding, and this buffer bar 52 is to utilize some latch fittings 53 to wear the relative position place and buffer bar 52 interlockings of this power transmission shaft 51 and sliding axle 44.
