FIG. 1 is a side view showing a roller blade of rotation type according to the present invention, FIG. 2 is a side view showing the wheel state when a rotation lever of the roller blade of rotation type according to the present invention is operated, and FIG. 3 is an exploded view showing the lower portion of a frame of the roller blade of rotation type according to the present invention. As shown in the figures, the present invention comprises a boot 10, a frame 20, a rotation axle 30, wheel mounting members 40a and 40b, wheels 50a and 50b, a brake 60 and a frame supporting member 70.
The frame 20 has a boot supporting plate 21, a rotation axle fixing stand 22, torsion spring supporting members 23a and 23b, rotation axle supporting rings 24a and 24b, a rotation lever torsion spring 25 and a rotation lever 26. The boot supporting plate 21 is secured to a sole of the boot 10 by a plurality of bolts and nuts to support the boot 10, and the rotation axle fixing stand 22 is formed at the lower center of the boot supporting plate 21 to be projected by a predetermined height.
The torsion spring supporting members 23a and 23b are fixed at the lower surface of the boot supporting plate 21 such that one is placed at an opposing side to the other centering around the rotation axle fixing stand 22 with a predetermined distance, and the rotation axle supporting rings 24a and 24b are respectively attached at the lower surfaces of the torsion spring supporting members 23a and 23b.
The rotation lever torsion spring 25 is formed at the rear side of the rotation axle fixing stand 22 to be inserted to a bolt which passes from the upper surface of the boot supporting plate 21 to the lower surface thereof and sequentially, the rotation lever 26 is inserted to the lower surface of the rotation lever torsion spring 25 and then is fixed by a nut.
Here, one end of the rotation lever torsion spring 25 is supported by the torsion spring supporting member 23a and the other end thereof is supported by the rotation lever 26.
The rotation axle 30 is inserted to the rotation axle supporting rings 24a and 24b such that both ends thereof are projected by a predetermined length, and the rotation axle 30 has a rotation axle projection 31, rotation axle torsion springs 32a and 32b and rotation axle torsion spring supporting screws 33a and 33b.
Firstly, the rotation axle projection 31 perpendicularly passes through the circumference of the rotation axle 30 and then is bent by 90° in one direction. The rotation axle torsion springs 32a and 32b are respectively inserted to the inner sides of the rotation axle supporting rings 24a and 24b through both ends of the rotation axle 30, one ends thereof being supported by the torsion spring supporting members 23a and 23b and the other ends thereof being supported by the rotation axle torsion spring supporting screws 33a and 33b fixed to the inner circumferences of the rotation axle torsion springs 32a and 32b.
The wheel mounting members 40a and 40b are of "U" shape and are respectively fixed to both ends of the rotation axle 30 to be symmetrical to each other with the frame supporting member 70 in the center. The wheel mounting member attaching plates for walking 41a and 41b attached at the same sides of the wheel mounting members 40a and 40b and the wheels 50a and 50b formed at the inner space of the wheel mounting members 40a and 40b are fixed by bolts passing through both sides of the wheel mounting members 40a and 40b.
The brake 60 is fixed at the open end of the wheel mounting member 40b by a bolt and a nut.
The frame supporting member 70 has a base plate 71, frame supporting stands 72a, 72b, 72c and 72d and a base plate for walking 73. The base plate 71 is rectangular in configuration with a predetermined thickness and is integrally formed with the frame supporting stands 72a, 72b, 72c and 72d. One ends of the frame supporting stands 72a, 72b, 72c and 72d are combined to the lower surface of the boot supporting plate 21 to be contact with the torsion spring supporting members 23a and 23b and the base plate for walking 73 is attached to the lower surface of the base plate 71.
The operation of the present invention as described above will now be described in detail.
Firstly, in the case that a user of a roller blade operates a rotation lever 26 in a forward direction to safely go up/down the stairs or go across a crosswalk or an unpaved street, the rotation axle projection 31 fixed to the rotation axle fixing stand 22 by the rotation lever 26 is released to rotate the rotation axle 30 by 90°. At the same time, the wheel mounting members 40a and 40b fixed to both ends of the rotation axle 30 are rotated, and the wheel mounting member attaching plates for walking 41a and 41b respectively attached at the same sides of the wheel mounting members 40a and 40b become placed on the same plane as the base plate for walking 73, thereby enabling the safe walking of the user.
In addition, in the case that the user rotates the brake 60 by 90° in a reverse direction to ride the roller blade again after crossing the street, the rotation axle projection 31 glidingly contacts with the side of the rotation lever 26 to be raised, and the rotation lever 26 moves in a forward direction. If the rotation axle projection 31 closely contacts with the rotation axle fixing stand 22, the rotation lever 26 fixes the rotation axle projection 31, thereby enabling the user to maintain the original state.
