BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kick-scooter, and more particularly, to a tri-cycle including a front wheel and a rear wheel and having a three-wheel configuration.

The tricycle has, in its configuration,

A steering unit configured to change a traveling direction by a steering means,

A riding section configured to ride to obtain propulsion,

And a folding unit configured to fold the steering unit and the boarding unit.

In the boarding section, two spreading beams are arranged on the left and right, and a rear wheel is mounted on the rear bottom of each spreading beam. Particularly, when the rear wheel is provided as an incline-caster, the propelling force can be obtained by cutting both sides of the ground with wheels like an inline skate while expanding both of the expanding beams in a horizontal direction or in a folding manner .

Next, the prior art relating to the present invention will be described.

In the example of FIG. 1, registered patent No. 1033655 (Mar. 29, 2011) is shown, in which a user grasps a handle and steers the direction of the front wheel at the bottom of the handle strut , And a footboard on the rear end of a cross beam arranged on the left and right sides, respectively. If a rear wheel provided as an incline caster is mounted on the footboard and a hinge is provided to spread the cross beam to the left and right, You can gain momentum by pushing or pulling.

In the example of Fig. 2, the registered patent No. 0928688 (Nov. 19, 2009) is shown in connection with the folding apparatus. For convenience of carrying, the folding unit 1 is folded to form a cross beam So that it can be folded in the direction of the side.

In the configuration of the folding unit 1, since the configuration of the cross beam is arranged in the body of the cross beam, the configuration for obtaining the driving propulsion force by expanding the cross beam in the left and right horizontal directions A structure that must be disposed at a position closer to the steering wheel than the steering wheel. However, since the steering strut side has a configuration for steering the front wheel, a configuration is provided in which a pair of left and right sides of the cross beam are deployed while supporting a load during traveling In fact, it is not the optimal place to place. In addition, since it is necessary to take a design by avoiding operation interference with the strut, the front wheel and the like, there is a great possibility that the deployment angle of the deployment beam is limited.

In addition, the configuration of the folded portion 1, which is placed on the body of a cross beam which continues to move in a leftward and rightward direction while enduring a load, plays a role of spreading and fixing a cross beam for use There is a possibility that a safety accident may occur while the vehicle is running.

In the deployment operation of the above-mentioned cross beam, the present invention prevents the unfolding of the unfolded beam fixation unfolded for running while reducing the interference with other components, .

The cross beams 220 take the form of a beam pipe and are arranged in parallel on the right and left sides of the traveling direction.

The rear wheel 230 is rotatably provided on a rear bottom surface of the cross beam 220. At this time, it can be attached by a known incline-caster method.

In the above-described overall configuration, a known prior art can be cited as necessary.

The following will concentrate on the folding unit 300, which is a substantial body of the present invention, as shown in FIG. 4 and below with reference to FIG. 4 to 7 illustrate a state in which the folding part 320 is extended and fixed to the strut 120 at right angles.

The folding unit 300 includes:

A base slide 310 having an empty pipe shape in the center and fitted to the outer periphery of the strut 120,

Left and right folding parts 320 arranged horizontally side by side on both sides of the base slide 310,

And a fixing plate 330 horizontally disposed around the outer periphery of the base slide 310 and having a substantially rectangular shape.

More specifically,

8, the slide part 311 is divided into a slide part 311 disposed on the upper side and a base part 312 disposed on the lower side. The slide part 311 is provided on the strut 120, (S up, s down) so that the outer periphery of the strut 120 can slide up and down, and the base part 312 is fixed to the outer periphery of the strut 120 so as not to move.

The folding part 320 is provided as a pair of right and left, and is configured to have a vertical refraction hinge connection 321b with the right and left sides of the base part 312. The folding part 320 is rotated in the vertical direction and folded (folded up) in parallel with the strut 120 (f up) with the vertical refraction hinge connection 321b as a rotation axis, (f down).

6B, the vertical refraction hinge connection 321b includes a hinge shaft b2 protruding from the side support b3 of the base part 312 and a hinge shaft b2 formed through the folding part 320 And the hinge shaft b1 is sandwiched between the hinge shaft b1 and the hinge shaft b1.

The front end 321 of the folding part 320 is formed with a fixing protrusion 321a projecting upward in the vertical direction and the cross beam 220 is connected to the rear end 322 of the folding part 320 . That is, the cross beam 220 is fixed to the rear end 322 of the part per side or is hinged to be horizontally refracted so as to rotate horizontally, so that the right and left cross beams 220 are developed with each other, .

The fixing plate 330 may be integrally formed on the outer peripheral edge of the lower end of the slide part 311 or may be separately manufactured and fixed so as not to move. On both left and right sides of the fixing plate 330, a fixing groove protrusion 331 capable of fixing the fixing protrusion 321a is formed so as to protrude upward in the vertical direction.

7, 9, and 10, a fixing groove 331a is formed in the fixing groove protrusion 331, and a hole corresponding to the fixing protrusion 321a is formed in the fixing groove protrusion 331. As shown in FIG. And the fixing protrusion 321a is fitted and fixed to the fixing groove 331a. 7, the fixing protrusion 321a is arc-shaped with the vertical refraction hinge connection 321b as a rotation axis. At this time, the fixing protrusion 321a is inserted into the fixing groove 331a The arc a1 is generated and the arc can not be performed. Therefore, in this state, there is a feature that the 'fixed' can never be released.

8, when the fixing protrusion 321a is inserted into the fixing groove of the fixing groove protrusion 331 and the folding part 320 is fixed so as not to move, The slide part 311 is lifted up so as to slide up along the length of the strut 120 and the fixing plate 330 and the fixing groove protrusion 331 are lifted up as one body, The fixing protrusion 321a fitted and fixed to the fixing groove 331a in the groove protrusion 331 is allowed to escape out of the fixing protrusion 321a to freely perform the arc of the example of FIG. Can be completely released.

In this way, both the left and right fixing protrusions 321a are simultaneously pulled out of the fixing grooves 331a in the fixing groove protrusions 331 to release the fixing on both the left and right sides. When the fixing is released, the folding part 320 may be folded up and folded up as shown in FIG. 10. After folded folding (f up) of the folding part 320 is performed to carry out storage and carrying,

When the tricycle of the present invention is used again, on the contrary, the folding part 320 is unfolded (down), and the slide part 311 is pulled down and slid down as shown in the example of FIG. At this time, the fixing protrusion 321a is fixed to the fixing groove 331a so that the folding part 320 is fixed so as not to move.

Next, with reference to FIGS. 11 and 12, consider an additional device to reliably hold the folded part 320 at a right angle from the strut 120. This is important as an apparatus for safety by preventing the stationary state from being released even under any circumstances during driving.

11, a fixing button insertion groove 313 is formed in the rear outer periphery of the slide part 311, and a fixing button 332 is inserted therein. When the slide part 311 is slid downward as shown in FIG. 8 and then the slide part 311 is positioned and the one end of the fixing button 332 is pushed, the other end of the fixing button 332 And is engaged with the fixing groove 120a formed in the outer periphery of the rear portion of the strut so that the fixing is completed. The fixing groove 120a is disposed at a position where the fixed state can be maintained. And is formed in a shape corresponding to the shape of the fixing button 332.

On the other hand, as shown in FIG. 12, when releasing the fixation, first, the other end of the fixing button 332 is pulled to release the hooking state. Then, 311 are lifted upwards and then the fixing protrusion 321a is released from the fixing groove 331a. In this way, the folded unit 300 can be completely released from being fixed so as not to be folded.
