In the present invention, in the construction of roller skates, four rollers are arranged in a row, but the central and rear rollers have the main surface on the same plane, and the front roller has the main surface slightly higher than the other roller main surfaces (2-4mm). By positioning the rollers to absorb and decelerate the impact force applied to each curved road surface as much as possible, it spreads the load on each roller and extends the service life of the rollers, while also allowing high speed driving to produce a skating effect. The purpose is to provide skates.

Conventional roller skates are generally configured to be driven by the front and rear rollers. Therefore, when driving at high speed on a curved road surface, a heavy impact force is added to the roller that touches the curved road surface, thereby shortening the service life of the roller, as well as driving speed. It was the cause of the decrease.

The present invention, in view of such a conventional problem, the roller itself is a water logger and each roller is prefabricated to be easily disassembled and combined with the frame to maintain the service life of the skate and at the same time configured so that high speed driving is not unreasonable. According to the accompanying drawings in detail as follows.

The frame (2) (3) is bolted to both sides of the frame fixing plate (1) with bolts and nuts (4), so that the center between the frames (2) and (3) and the center roller (5) (6) The front and rear rollers (7) (8) are arranged in a row, but the central rollers (5) (6) and the rear rollers (8) have the main surfaces (5a) (6a) and (8a) on a plane line The rollers 7 were such that the main surface 7a was positioned slightly higher (2-4 mm) than the other roller main surfaces. And the lower part of the frame (2) (3), which is connected to each other by the bolt (4) on the bottom surface of the roller (2a) (3a) fixed by bolts, nuts (9) in the shaft between the disassembled coupling To facilitate this, the roller body 11 is installed on the shaft 11 arranged as a bearing between the shaft spaces 2a and 3a, and each roller has a synthetic roller body 10 on the main surface of the recess 11a or It is configured to be integrally injection molded to the metal shaft 11 with the fitting portion 11b and to allow the rubber ring support ring 10a to be screwed with the bolt and nut 13 so that the rubber ring 12 can be easily replaced. It was.

In this invention, since four rollers are laid out in a row, the load of the human body is not distributed to each roller when the main surface of each roller touches the surface of the roller, and each roller is provided on the curved surface of the roller (5a) (6a) (7a) (8a). ) As the impact force is absorbed and distributed according to the degree of contact, the excessive impact force is not applied to each roller. Especially, the main surface (7a) of the front roller (7) is slightly higher than the main surface of the other rollers, so the main surface of the central roller (5) The center roller (5) touches the curved road surface before it reaches the curved road surface to absorb and mitigate the impact force received by directly contacting the curved road surface, and the central roller (5) (6) and the rear roller (8) also Since the unloaded load acts according to the degree of contact with the curved road surface, the conditions suitable for high-speed driving are maintained without overloading each roller.

In the present invention, the rollers (2) and (3) are screwed between the shaft shafts (2a) and (3a) with bolt nuts (9) to build up each roller. Inserted and fixed with a rubber ring support ring (10a) can be easily replaced by a rubber ring 12 in each roller and flame (2) (3) can be used while replacing each roller easily.

As such, the present invention can provide a roller skate that can produce a skating effect because the four rollers are arranged in a row, so that the high-speed driving can be performed while absorbing the impact force of the curved surface.

Claims (1)

Center rollers (5) (6) and front and rear rollers (7) (8) are arranged in a row in the center and front and rear between the flames (2) and (3), but the center rollers (5) and (6) The rollers 8 allow the major surfaces 5a, 6a and 8a to be positioned on a plane line, the front rollers 7 are positioned a little higher than the main rollers 7a with the other rollers, and the two members are bolted (4). The shafts 2a and 3a fixed by the bolts and nuts 9 are fixed to the lower surfaces of the frames 2 and 3 coupled to each other by the shafts, and the shafts 11 are formed as bearings between the shafts 2a and 3a. Roller roller 10 is installed in the roller body, and each roller is formed by mounting the rubber ring 12 on the roller body 10 so as to be installed by the bolt 13 with the rubber ring support ring 10a. .
