wheels

120A, 120B, 120C, and 120D may be configured to be covered by a separate wheel cover 112. The

wheels

120A, 120B, 120C, and 120D are relatively large compared to the conventional examples having small diameters, and the wheel cover 112 visually covers the

large diameter wheels

120A, 120B, 120C, and 120D. This can improve the appearance or prevent the water from splashing on the floor.

FIG. 2 is a perspective view illustrating a state viewed from the opposite direction to FIG. 1 in a state in which a part of the frame cover 111 and the wheel cover 112 are removed from FIG. 1. The

wheels

120A, 120B, 120C, and 120D included in the shoe roller module 100 related to the present invention are provided on the

wheel lifting units

130A, 130B, 130C, and 130D are formed to raise and lower the

wheels

120A, 120B, 120C, and 120D, respectively. The operation unit 140 is formed on one side of the frame 110 so that the user can directly operate. Lifting operation unit 150 is connected between the operation unit 140 and the wheel lifting unit (130A, 130B, 130C, 130D), the mechanical lifting force by the operation unit 140, the wheel lifting unit (130A, 130B, 130C, 130D) To pass).

3 is an exploded perspective view of the shoe roller module 100 according to the present invention, the elements of the frame 110, the wheel lifting unit 130, the operation unit 140 and the lifting operation unit 150 are presented.

The frame 110 is combined with the frame cover 111 and generally has a plate shape, and includes a wheel cover 112 at left and right sides. As a part that substantially supports the shoe (the weight of the user), it is positioned lower relative to the ground relative to the larger diameter wheels. Accordingly, when wearing a wheel shoe to which the roller module 100 for a shoe according to the present invention is applied, the overall center of gravity is lower than that of a conventional wheel shoe. The frame 110 may be used alone or in combination with a resin, a light metal or a fiber composite material, etc., which may be lightweight but have sufficient rigidity and flexibility. In terms of manufacturing, the frame 110 may be a method such as injection or press manufacturing to increase the mass productivity and easy to make a complex shape.

The wheel lifting unit 130 is supported to be rotatable relative to the frame 110 and is configured to lift the wheel 120 while rotating. Specifically, the wheel lifting unit 130 is a rotator 131 configured to be rotated in place with respect to the frame 110, and is disposed eccentrically with respect to the central axis of the rotator 131 to rotate the wheel 120 It may include a support wheel shaft 132, and the torque transmission unit 134 formed to apply a torque to rotate the rotator 131 by the lifting operation unit 150. In the shape, the rotator 131 may be formed in a disk shape. Correspondingly, a disk groove 133 in which the rotator 131 is accommodated may be formed in the frame 110. Since the wheel shaft 132 and the torque transmission part 134 supported by the rotator 131 are eccentric to the central axis of the rotator 131, the disk groove 133 is stable in the eccentric load to be caught on the rotator 131. I can support it. The disk groove 133 may include a bearing or a boss for a smooth and accurate rotation guide. The rotator 131 may be formed in a form in which a portion of the disk is cut out, or may be configured by a mechanical element such as a link or a combination thereof.

Figure 4 is a conceptual diagram for explaining the operation principle of the wheel lifting unit 130 associated with the present invention. As shown in FIG. 4, the central axis X2 of the wheel shaft 132 is spaced apart by a predetermined distance r1 for the lifting and lowering with respect to the central axis X1 of the rotator 131 included in the wheel lifting unit 130. In addition, the center axis (X3) of the torque transmission unit 134 is also a predetermined distance (r2) with respect to the center axis (X1) of the rotator 131 to rotate the rotator 131 by receiving the force of the lifting operation unit 150 Spaced apart). Accordingly, when the lifting operation unit 150 is moved, the torque transmission unit 134 converts it into a torque for rotating the rotator 131 and transmits it. When the rotator 131 is rotated, the wheel shaft 132 is eccentric. Since it rotates along the central axis X1, the lifting and lowering of the wheel 120 is made as a result.

Referring back to FIG. 3, the operation unit 140 is a pivot 141 which is rotatably formed with respect to one reference point of the frame 110 and is spaced apart from the reference point to connect the lever 141 and the lifting operation unit 150. The operation slot part 144 formed in the part 142 and the lever 141 and guides the pivot part 142 so that the lifting lowering operation part 150 can be moved in a linear direction while the pivoting part 142 rotates. It includes. The pivot part 142 rotates in place by the rotation support point formed in the frame 110. Lifting operation unit 150 includes a slide body 151 is formed to be able to slide in parallel with respect to the frame 110, the slide body 151 has a rail groove for guiding the operation slot 144 ( 152 is formed. The operation slot part 144 may be configured to receive an elastic force by the spring 145 which is restrained at one point of the slide body 151.

Lift operation unit 150 is connected to the wheel lifting unit (130A, 130B, 130C, 130D) to operate the wheel lifting unit (130A, 130B, 130C, 130D) at the same time. The lifting operation unit 150 is constrained by the torque transmission unit 134 and the lifting operation unit 150 moves horizontally while the torque transmission unit 134 rotates while the torque transmission unit 134 moves the lifting operation unit 150. The operation slot portion 161 may be provided to guide in a vertical direction with respect to. The operation slot part 161 is formed in the shape of a vertical groove, and the center axis X1 of the rotator 131 and the center axis X2 of the torque transmission part 134 while being moved in the horizontal direction of the slide body 151. The torque transmission unit 134 is guided in the vertical direction by an offset of. In this process, the rotator 131 is rotated. The protective slider 162 may be fitted to the torque transmitting part 134 to reduce wear caused by the direct friction between the torque transmitting part 134 and the operation slot part 161.

5 is a plan view showing a state in which the frame cover 111 of the shoe roller module 100 according to the present invention is removed, and FIG. 6 is a conceptual cross-sectional view for explaining the operation of the operation unit 140 according to the present invention.

As shown in these figures, when the pivot 142 constrained to the frame 110 is rotated by the lever 141, the slide pin 143 eccentrically disposed on the central axis of the pivot 142 is It pivots along the central axis of the pivot part 142. In this process, the slide pin 143 moves the operation slot 144 to apply a force in the direction to move the slide body 151. The operation slot part 144 may be perpendicular to the moving direction of the slide body 151.

An operation process of the lever 141 will be described step by step using FIGS. 6 to 9. That is, in FIG. 6A, the straight line formed by the center of the pivot portion 142 and the slide pin 143 is aligned to substantially match the moving direction of the operation slot portion 144. In this case, the shoe 200 is a state in which the wheel 120 is accommodated as shown in FIG. 7, and may be used for walking or running like a general shoe.

When the lever 141 is rotated 90 degrees clockwise, as shown in FIG. 6 (b), the slide pin 143 pivots along the center of the pivot portion 142 while moving the operation slot portion 144 downward. To exert strength. At this time, the slide body 151 connected to the operation slot unit 144 is also moved together, thereby rotating the wheel lifting unit 130 connected to the slide body 151. Accordingly, the wheel 120 is also lowered from the shoe 200 (see FIG. 8).

When the lever 141 is rotated 90 degrees clockwise as shown in FIG. 6 (c), the slide pin 143 pivots along the center of the pivot portion 142 while moving the operation slot 144 downward. The force will continue to be applied. At the end position of the lever 141, the straight line formed by the center of the pivot portion 142 and the slide pin 143 is aligned so as to substantially coincide with the moving direction of the operation slot portion 144. At this time, the wheel 120 is also lowered from the shoe 200 becomes a 'cloud mode' that can be rolled about the bottom surface (see Fig. 9). Even though the operation slot 144 receives the restoring force of the spring 145 to move in the reverse direction (ie, upward), the operation slot 144 cannot act because the pivot 142 cannot exert a torque that can be rotated counterclockwise. ) Cannot be moved upwards. That is, the position of the lever 141 at this time is that the wheel 120 is in a 'locked state' which is not arbitrarily moved upward by the user's load (see FIG. 9).

On the contrary, when the lever 141 is rotated counterclockwise in the state of FIG. 6C, the slide pin 143 moves the operation slot 144 upward. The spring 145 at this time provides an elastic force so that the operation slot 144 can be moved to the original position smoothly.

As such, the roller module 100 for a shoe according to the present invention has a structure in which the wheel 120 is disposed on the side of the shoe 200 to move up and down, and the wheel 120 is installed inside the sole of the shoe. While the size of the wheel can be significantly increased compared to the conventional case, since the position of the sole can be placed lower with respect to the ground, the center of gravity can be placed with sufficient speed to increase the sense of stability. In addition, the wheel lifting unit 130 is rotated in place, and the wheel shaft 132 is eccentrically arranged to simplify the lifting mechanism of the wheel while efficiently distributing the load transmitted to the wheel 120 to ensure structural stability and Durability can be obtained. In addition, when the wheel 120 is easily lifted by the rotating operation unit 140 and the wheel 120 is protruded, the pivot unit 142 and the slide pin 143 and the operation slot unit 144 are in an aligned state. As a result, the lever 141 is automatically locked so that the lever 141 is not released by the load or the impact transmitted to the wheel and the wheel 120 is not moved in the reverse direction.

The roller module for a shoe described above and a wheel shoe having the same are not limited to the configuration and method of the described embodiments. The above embodiments may be configured by selectively combining all or some of the embodiments so that various modifications can be made.
