Description
Technical field
The present invention relates to a kind of body-building apparatus, particularly a kind of adjustable buffering mechanism of treadmill.
Background technology
Laid-open U.S. Patents disclosed for No. 4350336 between the base of treadmill and pedal a buffer unit was set September 21 nineteen eighty-two, utilized the fulcrum that changes gap between base and the pedal to change the size of pedal with respect to user's buffer value; As everyone knows, it is constant establishing the position of body builder on treadmill deck, and the Support Position of pedal is near more from the body builder so, and pedal will become " firmly " with respect to the body builder, otherwise will feel " soft ".This technology can be regulated the body builder with respect to the buffer value of running plate, but some complexity of this technical pattern, and the treadmill cushion device of regulating position of the fulcrum is convenient inadequately.
Regulate the body builder and have plenty of with respect to the buffer value of running plate and utilize spring to realize, as No. 7077788, laid-open U.S. Patents on July 18th, 2006, this technology can well be regulated the body builder with respect to the buffer value of running plate, but this technology manufacturing cost is higher.
Regulate the body builder and have plenty of with respect to the buffer value of running plate that the structure of utilizing cantilever beam realizes, as No. 5976061, laid-open U.S. Patents on November 2nd, 1999, this technology is that pedal one end is fixed, the pedal other end is unfixing, one transportable fulcrum is arranged below the pedal, so just formed a cantilever beam structures, this technology is that the arm of force that mobile fulcrum makes cantilever beam act on pedal changes with respect to the body builder, thereby make the body builder variation take place with respect to the buffer value of running plate, this technology can be regulated the body builder with respect to the buffer value of running plate, but because this technology is a cantilever beam structures, the body builder may cause the phenomenon of double swerve when using treadmill, stability is not good enough.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of parts are few, simple for structure, the adjustable buffering mechanism of the treadmill of low cost of manufacture.
Another technical problem to be solved by this invention provides a kind of adjustable buffering mechanism of treadmill of easy to adjust, good stability.
The present invention solves above technical problem by the following technical programs:
The invention provides a kind of adjustable buffering mechanism of treadmill, described treadmill has:
One base;
One pedal, its rear and front end are fixed on the aforementioned base;
One front roller wheel and a rear roll laterally are hubbed on the aforementioned base, and the position is in the rear and front end of aforementioned pedal respectively;
One annular is run band, around the top side and the bottom side of aforementioned pedal, and can be enclosed within on aforementioned front roller wheel and the rear roll with rotating;
Have at least two adjustable buffering mechanisms to adopt mobilizable mode to be arranged between the base and pedal of aforementioned treadmill,, be formed with the gap between described base and the pedal in order to support the user to the downward pressure that aforementioned pedal applied; Adjustable buffering mechanism is provided with a handle, a baffle plate, three connectors at least;
The adjustable buffering mechanism of treadmill is provided with three rotatable cylindric objects that are arranged on aforementioned connector periphery at least, and the center that makes at least three connectors can pass aforementioned at least three cylindric objects respectively couples together baffle plate and handle; Aforementioned each cylindric object all one contacts at least with among pedal and the base, so that adjusting adjustable buffering mechanism and, the user lean on the front position and of pedal front end by the displacement between the back-end location of pedal rear end, thereby change the Support Position between base and the pedal, and then regulate the size of pedal with respect to user's buffer value.
The handle of the adjustable buffering mechanism of treadmill and baffle plate all are provided with three holes at least; The connector of the adjustable buffering mechanism of treadmill is a bolt, and described bolt is at least three.
Preferably, the described cylindric object of adjustable buffering mechanism is the nylon wheel of hollow; Described adjustable buffering mechanism is made up of a handle, a baffle plate, three bolts, three nylon wheels, 6 nuts, 4 screws, 4 nylon plush coppers, and described handle is made up of a handle shell, a handle gripper shoe.Described handle shell is provided with 4 screw holes; Described handle gripper shoe is provided with 4 screw holes, 3 bolt holes, 2 nylon plush copper through holes; Described baffle plate is provided with 3 bolt holes, 4 installing holes, 2 nylon plush copper through holes.
Three bolt holes that three bolts pass respectively on baffle plate and the handle couple together baffle plate and handle with leg-of-mutton space arrangement mode; Three bolts pass three nylon wheels respectively, and a nylon wheel of top contacts with pedal, and two following nylon wheels contact with base, and these three nylon wheels do not contact mutually, then with 6 nuts three bolting firmly; Two nylon plush coppers are separately positioned in two nylon plush copper through holes of handle gripper shoe; Two nylon plush coppers are separately positioned in two nylon plush copper through holes of baffle plate; 4 screws are fixed on handle shell on the handle gripper shoe.
The material of described nylon wheel and nylon plush copper is polyhexamethylene adipamide (PA66).
The effect of nylon plush copper is to prevent to abrade base.Adjustable buffering mechanism on base when mobile both sides have only the nylon plush copper to contact with base, again because PA66 has good wearability and self lubricity, so base is not easy to be scratched.
Each adjustable buffering mechanism all be arranged on pedal following and base above, and an adjustable buffering mechanism at least respectively is set in the both sides of base; The two ends of pedal are fixed on the base by stator and preceding fixed bolster.
