Abstract
A roller skate includes a roller frame having a pair of walls, and one or more plates secured between upper portions of the walls, a number of wheels are rotatably secured between the walls, the walls of the roller frame each includes a forwardly extending arm having an upper portion and a middle portion, a frontmost wheel is rotatably secured between the arms, and a reinforcing panel is secured between the arms and includes an inner peripheral surface having a curvature similar to a curvature of an outer peripheral portion of the frontmost wheel, to reinforce the arms, and to prevent the frontmost wheel from being contacted with the reinforcing panel.
Description
- 1. Field of the Invention
- The present invention relates to a roller skate, and more particularly to an in-line roller skate having a reinforcing structure to reinforce the wheel device.
- 2. Description of the Prior Art
- Typical roller skates comprise a roller frame to which a number of wheels are attached. The roller frame includes a pair of walls and a chamber formed between the walls for rotatably receiving the wheels. Some of the roller frames may include one or more ribs or bars coupled between the walls to reinforce the roller frame.
- U.S. Pat. No. 5,533,740 to Lin discloses one of the typical in-line roller skates and comprises a number of ribs or bars coupled between the side walls11 of the roller frame. However, the ribs or bars are not parallel to the wheels and may contact with the wheels when great forces are applied onto the wheels.
- Particularly, for the sport in-line roller skates for speeding purposes, great forces may be applied onto the front wheel, and will then applied onto the roller frame. However, the typical sport in-line roller skates have no suitably reinforced roller frame for reinforcing purposes.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional roller skates.
- The primary objective of the present invention is to provide a roller skate including a reinforcing structure to suitably reinforce the wheel device.
- In accordance with one aspect of the invention, there is provided a roller skate comprising a roller frame including a pair of walls each having an upper portion, and including at least one plate secured between said upper portions of said walls, to define a chamber between the walls and the at least one plate, a plurality of wheels are received in the chamber of the roller frame and rotatably secured between the walls, the walls of the roller frame each includes an arm extended forwardly therefrom and having an upper portion, a frontmost wheel is rotatably secured between the arms of the walls of the roller frame, and a reinforcing panel is secured between the arms and includes an inner peripheral surface having a curvature similar to a curvature of an outer peripheral portion of the frontmost wheel, to reinforce the arms, and to prevent the frontmost wheel from being contacted with the reinforcing panel.
- The arms each includes a middle portion, the reinforcing panel is extended from the upper portions of the arms toward the middle portions of the arms.
- Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
- FIG. 1 is a perspective view of a roller frame for a roller skate in accordance with the present invention;
- FIG. 2 is an enlarged partial plan view of the roller frame of the roller skate;
- FIG. 3 is a side schematic view of the roller skate; and
- FIGS. 4, 5 are side schematic views similar to FIG. 3, illustrating the operation of the roller frame of the roller skate.
- Referring to the drawings, and initially to FIGS.1-3, a roller skate in accordance with the present invention comprises a
roller frame 2 for supporting a boot 3 (FIGS. 3-5) thereon, and a number ofwheels 4 to be rotatably secured to theroller frame 2. - The
roller frame 2 includes a pair ofparallel walls 20, and one ormore plates 21 bridged or secured between theupper portions 29 of thewalls 20, to form or define achamber 22 within theroller frame 2 or between thewalls 20 and theplates 21. - The
walls 20 of theroller frame 2 include a number pairs oforifices 23 formed therein for receiving pivot shafts 24 (FIGS. 3-5) to which thewheels 4 are rotatably secured thereon. Thewheels 4 may thus be rotatably secured between thewalls 20 of theroller frame 2 with thepivot shafts 24 respectively. - The
walls 20 of theroller frame 2 each includes an extension or anarm 25 extended forwardly therefrom, and each having one of theorifices 23 formed therein for rotatably securing thefrontmost wheel 40 between thearms 25 with thepivot shaft 24. - The
roller frame 2 includes a reinforcingpanel 27 bridged or secured between thearms 25, and having an innerperipheral surface 28 facing toward thefrontmost wheel 40. The innerperipheral surface 28 of the reinforcingpanel 27 includes an inner diameter “R” greater than the outer diameter “r” of thewheel - As also best shown in FIG. 2, the inner
peripheral surface 28 of thereinforcing panel 27 preferably includes a curvature equals to or similar to or corresponding to the curvature of the outerperipheral portion 41 of thewheel arms 25 and theroller frame 2, and for preventing thefrontmost wheel 40 from being contacted with the reinforcingpanel 27 when great forced are applied onto the frontmost wheel 40 (FIGS. 4, 5). - It is preferable that the reinforcing
panel 27 is extended from theupper portion 29 toward the intermediate or inner or middle portions of thearms 25, and need not to be extended toward the bottom portions of thearms 25. - In operation, as shown in FIGS.3-5, while skating, great forces may be applied onto the
frontmost wheel 40, and then may be applied onto thearms 25 and theroller frame 2. The reinforcingpanel 27 that includes a curvature similar to or corresponding to the curvature of the outerperipheral portion 41 of thewheel arms 25 and theroller frame 2, to prevent thefrontmost wheel 40 from being contacted with the reinforcingpanel 27. - Accordingly, the roller skate in accordance with the present invention includes a reinforcing panel to suitably reinforce the arms of the roller frame, and to prevent the
frontmost wheel 40 from being contacted with the reinforcing panel. - Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
