It is further provided that the rotation axis is possibly coupled, wherein the directional cast is preferably to have an acute angle (θ) relative to the axis orthogonal to the scaffold.

In addition, the joints are preferably provided in a form independent of each of the directional casters.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1 or FIG. 2, the three-wheel caster skate 10 includes a first connection bar 20 and a second connection bar 21 coupled to each other at a predetermined angle with respect to the handle 50. And a first rotation bar 30 and a second rotation bar 31 rotatably coupled to each of the first connection bar 20 and the second connection bar 21.

In addition, the first connecting bar 20 and the second connecting bar 21 is coupled to the first torsion spring 40 to prevent the spaced apart by a predetermined angle for each, and to be restored to its original state when spaced apart. Doing.

In addition, the second torsion springs 41 coupled to the handle 50 to elastically support the first connection bar 20 and the second connection bar 21 are respectively connected to the first connection bar. The second connecting bar is pressed from the inside to the outside.

On the other hand, by providing an elastic piece 35 in the first rotating bar and the second rotating bar rotatably coupled to the first connecting bar and the second connecting bar, the elastic piece during the rotation of the first and second rotating bar It is to be restored to the original state by the action of the left and right torsional moment of the (35), and the directional caster 33 is coupled to the lower portion of the handle 50 and the first and second connecting bars to move the wheels along the direction of travel. It consists. In addition, the first and second rotary bars 30 and 31 are provided with a footrest 32 to raise the user's foot so that the three-wheel caster skate can proceed through the foot cloud on the footboard.

The footrest 32 is coupled to the upper surface of the first rotation bar 30 and the second rotation bar 31 by the rotation shaft 34 is rotatable in accordance with the movement of the footrest 32.

The handle 50 has a lower joint 52b connected to the directional caster 56 at one side, and the front and rear sides of the handle 50 are connected to the lower joint 52b by the upper joint 52a coupled by the pin shaft 54. It is possible to rotate left and right, and the handle is detachable through the removal of the pin shaft (54). In addition, the lower joint 52b and the directional caster 56 are provided in independent forms, respectively, in order to simultaneously obtain the rotational force of the directional caster and the braking force by the handle.

As shown in FIG. 5 or 6, the three-wheel cast skate 10 according to the present invention includes a braking part 60 connecting the lower joint 52b and the directional caster 33 of the handle 50. have. In this case, the braking unit 60 includes wires 62 drawn into the first and second connection bars 20 and 21 and the first and second rotation bars 30 and 31, and the first and second rotation bars. The disk 64 is provided in the directional caster 33 provided at the bottom of the connection, and the wire 62 and one side of the disk 64 are connected, and the central portion of the disk 64 is the directional caster 33. A shaft 66 for fixing with a support (not shown) of the &lt; RTI ID = 0.0 &gt;)&lt; / RTI &gt; To be connected. When the handle 50 connected to the joint 52 is pulled upward, the joint 52 moves upward and the wire 62 is pulled, and the disk 64 shaft 66 is pulled by pulling the wire 62. By close contact with the outer circumference of the wheel (not shown) and to provide a braking force to the wheel (not shown).

In addition, the directional casters 33 and 56 preferably have an acute angle θ based on the axis 33a perpendicular to the scaffold. This is because the thrust of the footrest of the scaffold can be more efficiently obtained by staggering the wheel with the axis through the acute angle.

Hereinafter, with reference to the accompanying drawings will be described in detail the operating state of the three-wheel caster skate of the present invention.

Referring to FIGS. 3 to 6, first, the first and second rotation bars 30 and 31 are pushed outwardly with the handle 50 being pushed out by the user on the footrest 32. Each rotates when it has an inclination angle inclined inward while being pushed outward. At this time, the tensile force acts on the first torsion spring 40 which connects the first and second connection bars 20 and 21, and conversely, the handle 50 and the first and second connection bars 20 and 21 are connected. Compression force is applied to the second torsion spring. In addition, the directional casters 33 positioned below the first and second rotation bars face in the direction in which the scaffold is advanced, and the scaffold 32 is rotated in the same direction as the foot cloud direction by the rotation shaft 34. . In this state, when the user removes the force F applied to the scaffold, the first torsion spring 40 connecting the first and second connection bars 20 and 21 is restored and returned to its original state. In this case, the first torsion spring 40 and the second torsion spring 41 are supported to correspond to each other, so that a constant angle can be maintained at all times. For example, when the first and second connection bars are moved outward, the tensile force of the first torsion spring acts, while the second torsion spring acts to compress the user's foot.

On the other hand, if you want to stop in the process of the propulsion force by holding the handle 50 in the direction of the arrow (F1) of the upper side so that the wire 62 of the brake unit 60 connected to the handle pulls the disk (64). Thus, the braking force can be applied to the wheels.

In addition, when the user does not use the handle 50, by removing the handle by removing the pin shaft 54 of the joint 52 of the handle 50, it is possible to board only by using the footrest.

When the user's foot rolling is repeatedly and continuously performed, the three-wheel caster skate gains propulsion force according to the change of direction of the directional caster, so that the user can proceed by self-propulsion without rolling a foot on the ground.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

The present invention has the following effects by the above configuration.

The present invention has the effect of obtaining the driving force by the self-direction and rotational movement in the state of placing the foot on the footrest.

In addition, the present invention has an effect that can prevent the safety accident by placing a braking unit at the same time to prevent the connecting bar is spaced more than a certain angle using a torsion spring.

And, the present invention has the effect of improving the storage and mobility through the detachable handle.
