Description

TREADMILL WITHOUT POWER SUPPLY

The present invention relates to a non-powered treadmill, and more particularly, to a non-powered treadmill that can easily balance a left and right while enhancing a motive effect, improve a charging performance by a user's motion, and implement an immediate braking function .

Generally, a treadmill is a mechanism that repeatedly performs walking or running according to a speed preset by a user in the form that the rotating belt is rotated by a motor.

However, when exercising with such a treadmill, the user had no way to calibrate his / her posture even though his / her body was abnormal or the posture was wrong unless instructed by the trainer. Particularly, when the user can not balance the body, the user is in a state of being tilted toward one side, so that there is a risk of adverse effect due to the exercise rather than a treadmill mechanism. In addition, So that a failure may occur.

Therefore, there is a demand for a treadmill capable of easily balancing the left and right balances and easily dispersing the load applied by the user during his / her exercise.

In addition, most of the treadmills use a power source to rotate the motor, thereby driving the rotating belt. Instead, the treadmill is driven in a non-powered mode to maximize the exercise effect, and the kinetic energy generated during the user's exercise A treadmill capable of driving a display device or the like of a treadmill to eliminate boredom is required.

When the user starts running or walking on the rotating belt 14, the main drum and the sub-drum are driven to rotate by the rotation of the rotating belt 14, The main gear is rotated, whereby the driven gear which is engaged with the main gear is rotated. The generator (26) coaxially connected to the driven gear by rotation of the driven gear is configured to rotate and generate electric power.

Here, the main gear and the driven gear are formed such that the diameter of the main gear is larger than the diameter of the driven gear. In this embodiment, the gear ratio is set in the range of 1: 3 to 1: 5, It is preferable to configure the driven gear so that the driven gear can be rotated much more during rotation to further improve the efficiency of generating and storing electric power by the generator 26. [

The track portion 10 is supported by the frame portion 30, and the frame portion 30 includes a plurality of frames.

The frame portion 30 includes a floor frame 31, a cover frame 32, a roller support frame 33, and a main support frame 34.

The bottom frame 31, as shown in Fig. 7, has a supporting member for supporting the sub-drum side, and is installed upright on the floor. In the bottom frame 31, a cover frame 32 arranged in the longitudinal direction on both longitudinal sides of the treadmill is disposed. The main frame 34 may be inserted into the bottom frame 31 by forming channels in a longitudinal direction on both sides thereof.

The roller supporting frame 33 includes a plurality of roller supporting frames 33a which are held in contact with a lower portion of the bar fixing frame 13 of the track portion 10, And a roller-supporting transverse frame (33b) for connecting and supporting the roller-supporting transverse frame (33b).

The roller support longitudinal frame 33a is supported by the main support frame 34 at both ends in the width direction of the treadmill. The main support frame (34) is disposed along the longitudinal direction on both longitudinal sides of the treadmill, and supports the roller supporting type frame.

The main support frame 34 includes a load measuring member 36 and a cushioning member 35. The load measuring member 36 and the cushioning member 35 are arranged at three positions 6 Respectively. The load measuring member 36 is installed at a lower portion of the roller supporting longitudinal frame 33a to measure a load conveyed from the roller supporting longitudinal frame and the control unit measures the load measured from the plurality of load measuring members 36 Value is displayed on the display screen 90 so that the user can easily grasp which of the left and right loads is concentrated and corrects the load so that the left and right balances can be easily maintained.

As shown in Fig. 5, the buffer member 35 is provided at a lower portion of the roller supporting longitudinal frame 33a and is formed into a substantially hollow cylindrical shape. The cushioning member 35 is preferably made of a material having elasticity, for example, a rubber material or a GBR material so as to be capable of buffering an impact force transmitted through the roller supporting type frame 33a.

A lower portion of the display unit 3 is provided with an elevation driving unit 40 for elevating and lowering the display unit, the track unit and the frame unit.

 6, 8A, and 8B, the elevation driving unit 40 includes an elevation driving motor 41, a lifting shaft 42, a lifting nut 42a, a fastening bracket 47, And a bracket (44).

As shown in Fig. 8B, the lifting shaft 42 is fastened to the fastening bracket 47 at a lower end so as to be hinged. An elevating nut 42a is screwed to the elevating shaft 42.

The lift nut 42a is connected to the elevation driving motor 41 and the elevation shaft is inserted and screwed in the inside.

The lifting nut and the lifting and lowering driving motor are coupled to a support bracket 44 through a bracket and a connection plate 43. The support bracket 44 is connected to the power generation unit And is connected to the track portion.

The fastening bracket 47 is fastened and supported on the upper part of the lifting and lowering frame 46.

When the elevating nut 42a is driven to rotate by the driving of the elevating driving motor 41, the elevating nut screwed to the elevating shaft 42, And is raised and lowered along the lifting shaft.

Accordingly, the supporting bracket 44, to which the elevating nut and the elevation driving motor are fastened, is raised and lowered, so that the power generation portion and the track portion connected to the supporting bracket are raised and lowered. At this time, since the elevating shaft is hingedly connected to the securing bracket, it is possible to accommodate that the securing angle with respect to the securing bracket is changed with the lifting and lowering of the elevating nut.

Thus, the user can freely set the desired exercise intensity by adjusting the inclination angle of the track portion.

Meanwhile, the electroless treadmill 1 according to the present invention includes a braking unit 50 for controlling the endless track motion of the rotating belt.

9, the braking unit 50 includes a brake drive motor 51, a brake 52, a brake bracket 53, and a switch 54. [

The braking bracket 53 is coaxially coupled to the drum shaft 22 of the main drum 21a and is engaged or disengaged with the brake 52 by driving the brake driving motor 51.

The brake 53 may be a mechanical brake or an electric brake, and is driven by the brake driving motor and is driven to be engaged / disengaged with the brake bracket by a control signal of the control unit. When the brake is constituted by an electric brake, the electric brake is brought into contact with the pair of switches 54 to apply a signal to the control unit about the current state of the electric brake.

The brake driving motor (51) is connected to the drum shaft, and when the speed exceeds a predetermined speed, the resistor is engaged / disengaged by an electrical signal of the control unit.

The control operation of the above-described braking unit having the above-described configuration will be described.

First, when it is detected from the load measuring member 36 whether or not a user's load acts on the track portion, the resistance of the brake driving motor is firstly engaged to fasten the electric brake to the brake bracket, Stop driving.

Then, when the user clicks the start button of the control panel or continuously detects a load within a predetermined time, the resistance of the brake driving motor is released to release the engagement between the brake bracket and the electric brake, And controls the rotatable belt to be rotatable.

This prevents the track portion from being driven by unintentional use by the user, and implements an immediate braking function by using the electric brakes.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
