The present invention relates to an inline skate, and more particularly, the frame on which the driving wheel of the inline skate is installed is divided into a front frame and a rear frame and is formed to be bent by a hinge pin. It relates to an inline skate designed to attenuate the rotation of the drive wheel by pressing the drive wheel by the provided brake wheel.

A number of inline skates are formed so that the frame portion on which the driving wheel is installed can be bent according to the bending of the shoe portion in the conventional inline skate (Patent Registration Nos. 2002-0068299, 2002-0078018, etc.). Flexing was useful for increasing the speed by allowing the feet to move more freely and lowering the fatigue of the feet and knees.

However, even in the above structure, even if the frame of the inline skate is bent and can be bent and moved according to the movement of the foot, if the friction with the ground is not applied, the propulsion force cannot be sufficiently received. As in the case of fixed, there is an inconvenience to move the feet in the diagonal direction, compared to the conventional inline skates in terms of fatigue has been improved, but to obtain the speed desired by the user was unreasonable.

In addition, in a conventional inline skate, the brake device is configured to brake the side of the driving wheel with a brake pad (Patent Application No. 1998-0032383), or to brake the brake pad directly against the rolling surface of the driving wheel. Method (Patent Application No. 2002-0078018) has been used, but in the case of the method in which the brake pad is in close contact with the driving wheels and braked as in the above case, suddenly braking or the driving wheel made of synthetic resin is easily worn. This occurs, which is undesirable in view of the safety of the user and the durability of the product.

In addition, in the conventional in-line skate, the anti-rotation device of the driving wheel pulls a pull line by hand while driving (patent application No. 2002-0078018), or by a ratchet method (patent application No. 1998-0032383). Each method is cumbersome to use during operation, and if a reverse rotation is required, the device has to be operated again.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to control the reverse rotation by using a braking wheel attached to the front end of the rear frame in the inline skate having a frame that is refracted It is to provide an inline skate to which propulsion force is given by using friction with the ground obtained by controlling reverse rotation.

Another object of the present invention is to provide an inline skate which reduces the wear of the driving wheel and prevents sudden braking by using the wheel as a braking means of the driving wheel.

The present invention for achieving the above object is an inline skate including a frame on which the shoe portion and the plurality of driving wheels are mounted, the frame is formed so that the front frame and the rear frame can be connected by the hinge pin and bend. The front end of the rear frame is provided with a braking wheel that attenuates the rotation of the driving wheel by pressing the driving wheel mounted on the front frame when the frame is bent over a predetermined angle.

In addition, the rear frame is preferably provided with a braking means, the braking means, the braking lever with a handle; A braking string to which a braking force is applied from the braking lever; And a braking wheel connected to the braking line to brake the driving wheel.

The brake wheel is provided with two wheels on an integral bracket, and the brake wheel is positioned in a space between the rear driving wheels mounted on the rear frame to press the two driving wheels simultaneously to attenuate rotation. do.

Hereinafter, described in detail with reference to the accompanying drawings inline skates according to the present invention. Prior to this, the terms or words used in this specification and claims should not be construed as being limited to their usual or dictionary meanings, and the inventors will properly describe the concept of terms in order to best explain their own design. Based on the principle that it can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only one of the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

1 is a conceptual view showing a structure of an inline skate according to the present invention, Figure 2 is an enlarged view of the anti-rotation wheel that is the main part of FIG.

According to the accompanying drawings, the inline skate according to the present invention is provided with a shoe frame 10 and a plurality of driving wheels on the frame and the base for connecting the shoe unit 10 and the frame, the frame is stretched The front frame 30a and the rear frame 30b are connected to each other by the hinge pin 31 so as to be possible.

The frame may be bound to the shoe part 10 by itself, but a flexible base may be bound to the bottom of the shoe part 10 for better fit and mobility, and the space between the base and the frame may be an elastic member. It is ideal to connect.

In this case, the elastic member may be installed in the front portion of the inline skate in the leaf spring 21 so as not to shake the central axis during the direction movement process, and the coil spring 23 having a good elasticity in order to reduce the fatigue of the foot in the rear portion In this case, the fixing bar 230 is installed on the rotating shaft of the coil spring, but one end of the fixing bar 230 is hinged with the lower part of the shoe so as to be rotated at an angle, and the other end of the fixing bar 230 is framed. It is inserted into the hole 310 formed on the upper surface of the fixing bar 230 is inserted into the hole 310 by melting the locking jaw to connect the shoe unit 10 and the frame, to ensure the stability when running.

On the other hand, at least two driving wheels are arranged in the front frame 30a and the rear frame 30b, respectively, and the reverse rotation preventing wheel 35 is arranged at the end of the front end of the rear frame 30b, but the rear frame ( 30b) the front end portion is bent upward by 40 ° to 70 ° with respect to the horizontal plane, and the reverse rotation preventing wheel 35 is in a horizontal state by a predetermined angle formed by the front end portion of the rear frame 30b from the horizontal plane. In this case, the second drive wheel 50b installed on the front frame 30a is spaced apart from the predetermined distance so as not to affect the driving, but when the heel is lifted by the need for driving, the rear frame moves corresponding to the heel ( 30b) is bent by the hinge pin 31 and the anti-rotation wheel (35) attached to the front end of the rear frame (30b) gradually rotates in close contact with the second drive wheel (50b) of the front frame (30a). I'm going to At this time, friction occurs between the second driving wheel 50b and the ground due to the braking force applied by the anti-rotation wheel 35 that rotates while pressing the rolling portion (the part in contact with the ground) of the second driving wheel 50b. This will give you momentum.

In order to move forward, the body needs frictional force, and when walking or running, the friction with the ground is used for the propulsion to correspond to the front heel of the foot, as described above. Lifting the heel, the rotation of the drive wheel 50 is controlled so that the friction occurs with the ground similar to the movement when the body walks or runs, it is possible to move forward easily, and also to give sufficient speed.

In addition, when the rear frame 30b is lifted by about 60 ° to 70 °, the anti-rotation wheel 35 presses the driving wheel of the front frame 30a so that the rear frame 30b is in close contact with the second driving wheel 50b. As the force is generated, it is possible to climb up stairs or slopes without slipping.

In the case of going up the stairs or slopes, it is preferable that the first driving wheel 50a is also stopped. To this end, gears are placed on the side surfaces of the first driving wheel 50a and the second driving wheel 50b, respectively. The coupling force is engaged between the first cogwheel and the second cogwheel, so that the stopping force is transmitted to the first drive wheel 50a even when only the second driving wheel 50b is braked by the anti-rotation wheel 35. It can be configured to.

At this time, the anti-rotation wheel 35 is to be rotated in close contact with the driving wheel 50, it may be a circular shape, it is possible to form a polygon of five or more in order to increase the pressure area, preferably octagonal As the shape of the wheels on the top rotates in close contact with the driving wheel 50, the rolling surface is continuously braking by pressing the driving wheel 50 continuously.

On the other hand, the rear frame 30b is preferably provided with a braking means 40 for braking the inline skates while driving, the braking means 40 according to the present invention, as shown in Figure 4, the braking lever 41 And a braking string 43 and a braking wheel 45.

The brake wheel may be formed to press and brake either the third drive wheel 50c or the fourth drive wheel 50d arranged in the rear frame, but for more reliable braking, the brake wheel may be installed in the rear frame 30b. In the spaced space between the third drive wheel (50c) and the fourth drive wheel (50d), the third driving wheel (50c) and the fourth driving wheel (50d) at the same time to give a braking force Preferably, two braking wheels 45 are laid.

In order to simultaneously brake the driving wheels arranged in the rear frame by the two brake wheels, the brake wheel 45 is arranged on the integral rotating hole 420, but the rotating hole 420 is fixed to the fixed shaft 410. It is formed to be rotated at a certain angle to the center.

When the braking lever 41 of the hand brake is pulled, the braking string 43 is pulled to rotate the pivoting hole 420 at a predetermined angle about the fixed shaft 410, and is provided at both ends of the pivoting hole 420. The brake wheels 45 respectively rotate and press the rolling portions of the third drive wheels 50c and the fourth drive wheels 50d at the same time to rotate the brakes. When the brake lever 41 is released, the tension of the brake wire 43 is released. As a result, the rotating hole 420 having the brake wheel 45 is returned to its original position by the recovery spring 430 fixed to one end of the rotating hole 420 and one side of the frame to release the braking force.

The shape of the brake wheel 45 mounted on the pivoting hole 420 may be circular, but may be preferably formed in a polygonal shape of five or more shapes such as the anti-rotation wheel 35.

In the case of braking using the braking wheel 45 as described above, the braking area is smaller than that of the braking part of the driving wheel by the brake pad, the wear of the driving wheel is less, and the accident caused by the sudden braking is prevented. do.

According to the inline skate according to the present invention, by using a refracted frame, even when driving without a separate operation by lifting the rear frame with the anti-rotation wheel mounted at a predetermined angle obtained by controlling the reverse rotation and the reverse rotation at the same time Inline skates are provided that provide impulse force using friction with the ground.

In addition, the use of the wheel as a braking means of the driving wheel provides an inline skate that reduces wear of the driving wheel and prevents sudden braking.
