Description

Skate Board

The present invention relates to a skateboard to which the directional caster is attached to enjoy on the ground, and more specifically, the operator moves the weight up and down the board by simply moving the feet up and down in the front and rear directions, respectively. It is related to a skateboard configured to move the board forward and backward without limiting the ground by swinging the caster mounted at the front and rear by switching the movement to the left and right swing movements within a limited angle.

Conventional directional casters are attached to the skateboard is connected by a connecting element provided with an elastic body so that the front and rear boards are spaced apart and elastically restored when twisted or bent, and one or more directional casters are provided on the bottom slope of each board. It is a structure that is equipped with two.

In the conventional skateboard configured as described above, propulsion force is obtained while the board proceeds in an “S” shape by an operation in which the driver's foot is repeatedly rotated repeatedly several times during driving.

Therefore, the conventional board is limited in place because the boarding place should be wide in order to prevent contact with other boards, it is possible to give ankle to the ankle because the foot must be rotated repeatedly alternately, In addition, since it requires a considerable amount of time for the skilled person, it is difficult for a beginner to drive while holding a foot on the front and rear boards, and thus it is not easy to enjoy it.

The present invention relates to a skateboard to which a directional caster is attached, and the driver places both feet on the board 100 and alternately shifts weight without the need for a cumbersome motion that causes the ground or the two feet to swing repeatedly. The purpose is to provide a skateboard that can gain momentum only by movement.

In addition, the purpose is to provide a skateboard that can be easily enjoyed on board the narrow road.

It is also an object of the present invention to provide a skateboard capable of generating power transmission and generating propulsion force efficiently.

Another object of the present invention is to configure the skate blades instead of the front wheel / rear wheel to be able to safely ride on the ice.

According to the present invention, when the driver swings up and down the board 100 by a simple operation of placing both feet before and after the board 100 and shifting weights alternately, the pair of bevel gears 310 and 340 which are the power transmission means 300. Forward and backward direction, which is a driving means fixed to the inclined surface 421 of the left and right frames 410 and 420 by rotating the left and right frames 410 and 420 by increasing power and switching power in the horizontal direction. The caster 500 is configured to advance the board.

The present invention is composed of a long elliptical in the front, rear direction and the board 100 is configured to allow the driver to swing the foot 900 before and after;

The body 200 is axially coupled to the board 100 and the left and right frames 410 and 420 to be fluidly coupled to the board 100. The body 200 is axially coupled to the body 200 and is formed to extend forwardly and backwardly to have a limited angle. Left and right frames that swing in movement, interlocking movement (410, 420)

And power transmission means 300 for power transmission of the up and down movement of the board 100 to the swing movement of the left and right frames 410 and 420:

The driving means is formed on the inclined surfaces at both ends of the left and right frames (410, 420).

The present invention puts both feet on the board alternately without the need for cumbersome motions that cause the driver to hit the ground with one foot or to repeatedly swing the driver's feet in order to generate propulsion force on the skateboard. Simple movements to transfer weight will have the effect of gaining momentum.

In addition, since the driving force is generated by the left and right rocking motion of the left, right frame to restrain the symmetry mutually symmetrical, it is possible to easily enjoy the board 100 in the narrow road.

In addition, since it is supported by four casters, stable driving is possible while maintaining equilibrium with the ground without fear of falling or losing balance, so that even beginners can easily enjoy it safely regardless of the skill of the driver.

In addition, a pair of bevel gears convert the up and down rocking motion of the board into the swing motion of the left and right frames, so that the power is transmitted, thereby ensuring a power transmission.

In addition, since the front and rear four directional casters generate a driving force at the same time, there is a fast speed effect.

Another object of the present invention is to configure the skate blades instead of the front wheel / rear wheel to safely ride on the ice.

Preferred embodiments of the present invention will be described in detail with reference to FIGS. 1 to 6.

First of all, for the sake of understanding, the direction in which the board proceeds with the skater on board, that is, the left side of the figure is "front", the right side of the figure is "rear", the right side of the direction is "right", The left side will be referred to collectively as "left".

The board 100 has an elliptical shape long in the front and rear directions so that the driver can put the foot 900, and the upper bracket 110 is fixed to the bottom center.

The body 200 is supported by a rib 203 formed at the front and rear ends of the upper plate 201 and the lower plate 202 spaced apart in a predetermined space 205 and installed horizontally parallel, rib ( 203 is configured to have a suitable width so that the left and right frames 410 and 420 to swing in a limited angle by contacting one side of the left and right frames 410 and 420 when swinging.

In addition, the vertical axis hole is formed to be spaced apart from the center by a predetermined distance so that the 1.2 vertical axis (330.340) is shaft-bound.

In addition, a lower bracket 206 is protruded from the upper plate 201, and is horizontally coupled to the upper bracket 110 by a horizontal pin 120.

The left and right frames 410 and 420 are integrally formed in pairs in front and rear, and are coupled to the first and second vertical shafts 330 and 340 by vertical shaft holes formed in a central portion, respectively. Left and right gear teeth 412 and 422 are formed at one side of the outer circumferential surface of the right boss 411 and 421.

The left and right frames 410 and 420 configured as described above are configured to be engaged with each other by the left and right gear teeth 412 and 422 so as to be mutually restrained within a limited angle, and to the left and right spaces 205 of the body 200. Is inserted into the bearing body 210 is coupled to the body 200 by the first and second vertical shafts 330 and 340 to be rotatable.

In addition, the first vertical shaft 330 is protruded to the upper portion of the body 200 so as to transmit power to the second bevel gear 320 is axially coupled.

In addition, the directional casters 500, which are driving means, are mounted on the inclined surfaces 421 having the rear sides inclined upward at both ends of the left and right frames 410 and 420.

The power transmission means 300 is installed to convert the up and down rocking motion of the board 100 to a suitable speed to convert to the swing motion of the left and right frames (410,420).

That is, the first bevel gear 310 fixed to the upper bracket 110, the horizontal pin 120 of the body 100, and the second bevel gear 320 that are axially coupled to the first vertical shaft 330 are tooth-bonded. Will be configured.

Since the first bevel gear 310 and the second bevel gear 320 are engaged in a limited angle range and are reciprocated to rotate, they may form a gear tooth only in a limited range, and the speed ratio may vary according to the number of gears. It is advantageous that the first bevel gear 310 is larger in diameter than the second bevel gear 320 in order to be able to swing the left and right frames 410 and 420 at a large angle even in a small angle up and down movement of the board 100.

In addition, the first bevel gear 310 may be configured to be geared with the second bevel gear by forming gear teeth on the outer circumferential surface of the upper bracket 110 without attaching a separate gear.

The driving means 500 is composed of directional casters which are installed at both ends of the left and right frames 410 and 420, respectively, and are fixedly mounted to have a rear surface upward.

In addition, the directional caster is advantageously configured to operate only within a limited angle (about 45 degrees left and right) (not shown).

The operation state of the present invention configured as described above will be described in detail with reference to FIG. 7 as follows.

When the driver puts the foot 900 on the front and rear of the board 100 and puts the weight on the front side, the first bevel gear 310 rotates clockwise.

At this time, the second bevel gear 320, which is engaged with the first bevel gear 310, rotates in a counterclockwise direction by converting the speed and the direction of motion, and is rotated by the second bevel gear 320. The vertical axis 330 is rotated in the counterclockwise direction.

When the first vertical axis 330 rotates in the counterclockwise direction, the left frame 410 fixedly mounted therein swings in the counterclockwise direction by converting the movement angle and speed, and is installed symmetrically at this time. The right frame 420 swings in a clockwise direction symmetrically with the left frame 410.

Subsequently, when the driver moves the weight to the rear side, the rotation direction of the first and second bevel gears 310 and 320 is changed by the above method, thereby swinging the left and right frames 410 and 420, thereby allowing continuous power transmission.

Such swing movement of the left and right frames 410 and 420 is performed only within a limited angle. When the left and right frames 410 and 420 are rotated to a predetermined angle, ribs are formed before and after the body 200. This is because it is in contact with 203 and can no longer rotate.

 By such an operation, the board 100 connected to the left and right frames 410 and 420 to restrain the vertical movement is also possible only within a limited angle.

In addition, the pair of left and right frames 410 and 420 repeat the relative operation of opening the rear side when the front side is lifted and the front side when the rear side is lifted.

By the above operation, the four directional casters 500, which are the driving means 500 installed on the inclined surfaces at both ends of the left and right frames 410 and 420, have a symmetrical shape as shown in FIG. Since the driving force is generated while drawing the trajectories (700,800), the skateboard can be driven straight with strong force.

 In addition, since the swing operation of either the left or right frame 410, 420 of the front or rear side is always kept open, the driver has the advantage of always enjoying the skateboard safely without falling or losing balance.

When the swing motion of the left and right frames 410 and 420, the driving force generation process of the directional caster 500 is as follows.

When the left and right frames 410 and 420 are retracted and retracted, the directional casters 500 attached to the inclined surfaces 421 at both ends generate a force to tangentially move from the center point of rotation, so that the directional casters 500 tangentially. Try to be aligned

However, the directional casters 500 attached to the inclined surfaces at both ends of the left and right frames 410 and 420 are subjected to a force to align with the inclined surfaces.

Therefore, at a point where the force to tangentially advance and the force to align the directional caster 500 are balanced, a constant angle a is formed and the directional caster 500 is aligned in the diagonal direction.

When the left and right frames 410 and 420 swing by the directional casters 500 that form a constant angle (a) with the tangential surface by such a force, the left and right directional casters 500 generate a propulsion inclined at a predetermined angle. do.

However, in the left and right frames 410 and 420 which are operated to be constrained in left and right symmetry as in the present invention, the force to proceed to the left and right as shown in the synthesis of the forces is dissipated and the left and right directional casters 500 are forward. The combined board is able to push the board 100 with a strong force (F) while going straight forward.

Referring to the method of changing the direction of the skateboard of the present invention as follows.

When the driver turns to the left and lowers, one foot 900 loads the body weight on the rear left side of the board 100 and the other foot momentarily puts the body counterclockwise on the front board 100. If turned to the front directional caster 500 is instantaneously aligned in the left direction is to change the direction.

In the same way, when changing the direction to the right, one foot (900) puts the weight of the body on the front left side and the other foot (900) is instantaneously put the right foot (900) on the back board (100) When turned clockwise, the rear directional caster 500 is instantaneously aligned to the left so that the direction is switched to the right.

8 is another embodiment, the skating blade is formed on the directional caster 500 is configured to be easily worn on ice.

Unlike the existing skateboard 100, the skateboard of the present invention can move without occupying the ice by foot, and is supported by four skate blades 600, so that the skate can be stably enjoyed, and the driving force is generated in a straight state. Therefore, it is configured to give speed easily even in a narrow space.

Since the operation method is the same as the above description, the description will be omitted without overlapping.
