With reference to above-mentioned each figure, framework 14 and support 10 all form with the processing and manufacturing of rectangle steel pipe, support 10 and 14 vertical connections of framework, but the junction firm welding is fixed frame, or the

brace

23 that is welded on the framework 14 in junction usefulness is connected with

support

10 by the folding shaft 9 that has

knob

22, become collapsible frame, can not unclamp the

knob

22 of folding shaft by the time spent at treadmill for collapsible frame, framework 14 can be started very easily with

support

10 and be overlapped, then

knob

22 is screwed the storage area that can reduce treadmill, this Foldable running apparatus more is applicable to the user that big city living space is comparatively nervous, framework 14 is fixed with

reinforcement

17 equably, the

wooden slide plate

19 that the support tread belt is housed on it is to support the runner,

front axle

21 and

rear axle

16 are separately fixed at the two ends of framework 14, front roll 24 and

back roll

15 are housed respectively on diaxon, anti-skidding running is with 20 before the

band gripper shoe

19 of running is contained in, on the back roll, regulated power supply 1 is installed in the front end of framework, motor is installed on the motor mounting axle of framework 14 by tubular mount pad,

flywheel

6 is contained on the motor reel with

drive pulley

7, belt 8 is sleeved on

drive pulley

7 and is fixed on the driven

pulley

12 of

front axle

21 1 ends, drive

pulley

7 drives driven

pulley

12 by belt 8 when motor rotates, before, back roll, tread belt is rotated simultaneously, for belt 8 is skidded, belt is housed on framework 14 regulates bolt 4, one end of bolt is connected with

orifice plate

33 on being fixed on motor casing, the other end is connected with orifice plate on being contained in framework 14, screw or unclamp bolt 4, can regulate the rate of tension of belt 8, in order to regulate velocity,

control sensor

5 is housed on the motor 2,

control sensor

5 feeds back to the running speed of regulated power supply 1 with the stable electrical motivation with the rotary speed of motor, the demonstration sensor 11 that is contained on the framework 14 is transferred to display on the instrument control panel 27 with the speed of tread belt, to show velocity, the accumulative total running time, add up to run mileage, instantaneous values such as physical consumption.Can control the rotating speed of motor by the velocity control knob on the instrument control panel 27, reaching the velocity that the person taking exercise requires, and be stable on this velocity.

For reaching the purpose of multiple exercise, on framework 14, be welded with the

jack

3 of device to pedal is installed,

device

33 to pedal can be inserted in the jack as required, just can carry out the simulated exercise of stepping bicycle, rowing machine jack 14 also is equipped with in both sides at framework 14, when needs are rowed the boat exercise, the hydraulic type rowing machine can be inserted in the rowing machine jack, the inserting column 31 on both sides, chair 29 bottom of will rowing the boat again is inserted in the

chair jack

18 of rowing the boat of framework 14 both sides, the person taking exercise is sitting in the exercise of can rowing the boat on the chair of rowing the boat, backrest 30 changeable angles of chair of rowing the boat make the person taking exercise have only exercise posture, and the person taking exercise is sitting on the chair of rowing the boat two and rides and doing to take exercise to pedal on the device to pedal when moving to pedal.

(see figure 5) at first is inserted in attaching plug on the household AC power when using this treadmill, velocity control knob 37 on the instrument control panel turns clockwise, regulated power supply 1 is just to motor 2 output powers, the motor rotation is also passed through

drive pulley

7, driving belt 8, driven

pulley

12 drives front roll 24 rotations, before being sleeved on,

tread belt

20 on the back roll is just done translational motion on support skid 19, the person taking exercise just can do taking exercise by running of various speed on treadmill, this moment, the movement velocity of velocity sensor 11 mensuration tread belt was delivered to multifunction display 40 demonstration velocities, the accumulative total running time, add up to run mileage, numerical value such as physical consumption.The rotating speed that

control sensor

5 is measured motor 2 is compared the difference amplifier that it feeds back in the regulated power supply 1 with the speed set-point of being sent here by velocity control knob, its difference output is exported to reach stable motor given speed the electric power of motor 2 by control circuit, drive circuit and power component control, the speed that clockwise rotates the velocity control knob motor increases, the speed of service of tread belt improves, otherwise, be rotated counterclockwise velocity control knob, the speed of motor lowers, and it is slow that the speed of service of tread belt becomes.

1, a kind of treadmill is mainly by frame, motor, regulated power supply, tread belt and instrument control panel are formed, it is characterized in that framework (14) and vertical connection of support (10), the junction is the folding shaft (9) that a framework (14) can have rib-loop around an end of this rotation, the other end person of the installing knob (22) of folding shaft, front axle (21) and rear axle (16) are contained in the two ends of framework (14) respectively, front roll (24) is contained on the antero posterior axis with bearing holder (housing, cover) respectively with back roll (15), tread belt (20) installs around on the cylinder of front and back, support skid (19) is housed under the tread belt, driven pulley (12) is tightly packed in an end of front roll, motor (2), regulated power supply (1) is installed in the front end of framework (14), control sensor (5) is contained on the motor (2), velocity sensor (11) is installed on the framework that abuts against driven pulley (12), belt is regulated bolt (4) one ends and is connected on the orifice plate (33) of motor casing, the other end is connected on the orifice plate that is welded in the framework front end, be welded with cast mount pad (38) on the shell of motor (2), the both sides welding of framework (14) has the motor mounting plate (26) of motor mounting axle (39), treadmill arm-rest frame (28) is installed on the top of support (10), and instrument control panel (27) is installed on the arm-rest frame (28).

2, treadmill according to claim 1, it is characterized in that being welded with device female receptacle (3) to pedal at the front end of framework (14), be welded with the female receptacle (13) that the hydraulic type rowing machine can be installed in the both sides of framework (14), framework (14) the both sides chair jack (18) of rowing the boat, two inserting columns (31) of chair (29) bottom of rowing the boat can insert, and rotary back are installed below the framework (14) to support (32).
