Description
- 1. Field of the Invention
- The present invention relates to roller shoe having a brake pad, and more particularly, to a roller shoe having a brake pad which can perform a stable brake operation as the brake pad is frictioned to the ground if the ankle is bent further a bit more backward by detachably mounting a brake pad of high strength on the heel portion of an inclined plane of the shoe sole where a wheel is mounted.
- 2. Description of the Related Art
- As generally known, recently, with the activation of various types of leisure sports such as skiing, inline skating, water skiing, paragliding and so on, a variety of leisure and sports goods are being developed which are more convenient and can add fun. This development of new leisure and sports goods is activating the opening of a new field of leisure sports has been activated and attracting the public's attention.
- Particularly, inline skating or the like has been come into wide use recently, thus a lot of people enjoys leisure and sports along with the pursuit of both fun and health promotion.
- Therefore, a wide variety of modified leisure and sports goods are being poured into the market. Most of such modified leisure and sports goods are made by adapting existing leisure and sport goods or appliances to household articles for the purpose of enjoying leisure in daily life.
- For instance, a roller shoe made by applying an inline skate or roller skate to a shoe is one example thereof. The roller shoe is devised to serve as both sports shoe function and roller skate or inline skate function by mounting a wheel on the heel portion of the sole of a typical sports shoe. That is, in order to serve as the sports shoe function without difficulty, it has a an inclined plane of a predetermined angle formed on the heel portion of the sole of the sports shoe and a support member for supporting the wheel insertingly mounted on a concave groove formed on the inclined plane, with the wheel being mounted on the support member.
- Hence, it has no difficulty in carrying out the function of a typical sports shoe, and it has a structure where, if one's ankle is bent enough to contact the heel portion of the shoe onto the ground for quick movement, the wheel mounted on the heel portion is contacted with the ground.
- However, since the above-mentioned roller shoe has no member having a separate brake function mounted on the lower surface of the shoe sole, a brake is operated only using the shoe sole under a circumference that a quick brake operation is required. That is to say, braking has to be done by a friction force between the shoe sole and the ground. Therefore, there occurs a problem that the shoe sole is excessively worn down and thus it is made impossible to use this high-priced roller shoe for a long time.
- Especially, the wheel of the roller shoe is contacted to the ground only when the ankle is bent toward the heel portion at a predetermined angle. In this state, the front end of the sole of the roller shoe gets floated in the air, so it is almost impossible to operate the brake quickly using the sole at the front end of the wheel. Consequently, the brake cannot be operated smoothly, and thus the possibility of a safety accident is very high.
- The present invention is designed in consideration of the problems of the prior art, and therefore it is an object of the present invention to provide a roller shoe having a brake pad which can perform a stable brake operation as the brake pad is frictioned to the ground if the ankle is bent further a bit more backward by detachably mounting a brake pad of high strength on the heel portion of an inclined plane of the shoe sole where a wheel is mounted.
- To achieve the above object, there is provided a roller shoe having a brake pad according to a preferred embodiment of the present invention, comprising: a wheel for moving a roller shoe wearer by rotation which is housed in a concave groove formed on an inclined plane at the heel portion of the sole of a sports shoe so as to be axially coupled to the concave groove; and a brake unit which is mounted on the heel portion of the sole where the wheel is mounted and performs a brake function by a friction to the ground by bending the ankle backward at a predetermined angle.
- Preferably, there is provided a roller shoe having a brake pad, the brake unit consists of a coupling groove having a fixed jaw formed on the marginal bottom face for fixing the brake pad to the sole, an opening formed on the front end thereof and a brake pad frictioned to the ground and mounted on the coupling groove.
- More preferably, there is provided a roller shoe having a brake pad, wherein a protrusion is formed on the front end portion of the brake pad which has a high friction coefficient and tensile strength, extends to the brake pad and is spaced apart from the wheel at a predetermined distance to perform a secondary brake function upon a friction between the brake pad and the ground.
- Other objects and aspects of the present invention will become apparent from the following description of embodiments with reference to the accompanying drawing in which:
- FIG. 1 is a side view showing the profile of a roller shoe having a brake pad according to a preferred embodiment of the present invention; and
- FIG. 2 is a bottom view showing the bottom of the roller shoe having a brake pad according to the preferred embodiment of the present invention;
- FIG. 3 is a partial perspective view showing a mounting state of a brake pad of the roller shoe having a brake pad according to the preferred embodiment of the present invention;
- FIG. 4 is a side sectional view showing the mounting state of a brake pad of the roller shoe having a brake pad according to the preferred embodiment of the present invention; and
- FIGS. 5a and 5 b are a schematic view showing a used state of a brake of the roller shoe having the brake pad according to the preferred embodiment of the present invention.
- Hereinafter, the present invention will be described in more detail referring to the drawings.
- FIG. 1 is a side view showing the profile of a roller shoe having a brake pad according to a preferred embodiment of the present invention and FIG. 2 is a bottom view showing the bottom of the roller shoe having a brake pad according to the preferred embodiment of the present invention.
- Referring to these, the roller shoe according to the preferred embodiment of the present invention is devised to serve as both sports shoe function and roller skate or inline skate function by housing a
wheel 20 in aninclined plane 8 at the heel portion of the sole of a typical sports shoe 4. That is, in order to serve as the sports shoe function without difficulty, it has a aninclined plane 8 of a predetermined angle formed on the heel portion of the sole of the sports shoe and a support member for supporting thewheel 20 insetingly housed in aconcave groove 22 formed on the inclined plane, with thewheel 20 being mounted on the support member. - If an unexpected situation occurs while riding the
roller shoe 2, the transport speed of theroller shoe 2 has to be sharply decreased. At this time, in a case that a brake function is performed using the sole 6 of theshoe 2, the wearer falls flat on its front. This is the same principle as the one that, when a front brake is operated in a bicycle riding at a high speed, the body of the user leans forward to become dangerous. Particularly, the ankle must be bent at a predetermined angle enough to make theinclined plane 8 contacted to the ground in order to ride theroller shoe 2, it is very dangerous to perform the brake function using the shoe sole from a structural viewpoint. - Therefore, it is preferable that a
brake unit 30 is located on theinclined plane 8 having thewheel 20 housed therein. More preferably, thebrake unit 30 is housed in thecoupling groove 36 formed at the heel portion of theroller shoe 2. - Of the
brake unit 30 of theroller shoe 2 having a brake pad according to the present invention, thebrake pad 32 is detachably mounted in thecoupling groove 36 having the wheel housed therein. In other words, when thebrake pad 32 is worn down because the user often operates the brake function using thebrake pad 32, thebrake pad 32 can be replaced by another for a continuous use. - Additionally, in the
concave groove 22, a support member for bilaterally supporting theaxis 24 of thewheel 20 is installed, with thewheel 20 being inserted into the support member. - FIG. 3 is a partial perspective view showing a mounting state of a brake pad of the roller shoe having a brake pad according to the preferred embodiment of the present invention and FIG. 4 is a side sectional view showing the mounting state of a brake pad of the roller shoe having a brake pad according to the one embodiment of the present invention.
- Referring to these drawings, the
brake pad 32 of theroller shoe 2 having a brake pad according to the present invention is detachably housed in thecoupling groove 36 having the wheel housed therein. On a rear section of the sole 6, thecoupling groove 36 for receiving thebrake pad 32 is formed at the rear end portion of theconcave groove 22. Thecoupling groove 36 has a jaw, with its front end portion opened. - Thusly, when the
brake pad 32 is inserted through a front end opening of thecoupling groove 36, thebrake pad 32 is firmly mounted on the heel portion of the shoe. Especially, upon a friction between thebrake pad 32 and the ground, thebrake pad 32 is given a force toward the heel portion by a forward transport speed, thebrake pad 32 does not slip out to the front end opening of thecoupling groove 36. - Additionally, on the front end portion of the
brake pad 32, aprotrusion 34 is protruded, which carries out an auxiliary brake function by contacting the outer circumferential face of thewheel 20, when thebrake pad 32 is given a force by the friction with the ground in a state of being spaced apart from thewheel 20 at a predetermined distance. - The functions and operations of the roller shoe having the brake pad according to the one embodiment of the present invention will be described in detail with reference to the accompanying drawings.
- FIGS. 5a and 5 b are a schematic view showing a used state of a brake of the roller shoe having the brake pad according to the one embodiment of the present invention.
- Firstly, in a state that the user is wearing the
roller shoe 2 having the brake pad according to the preferred embodiment of the present invention, if there occurs a situation where the brake function has to be performed while riding theroller shoe 2 on a road on at a constant speed, the user bents its ankle toward a rear surface at a predetermined angle. - Then, as the
brake pad 32 is contacted on the ground to cause friction between them, thebrake pad 32 is given a force relative to the ground. As a consequence, a primary brake function is performed above all. At this time, since thebrake pad 32 is mounted on the rear end of thewheel 20, the user can make thebrake pad 32 contacted to the ground with ease only by bending the ankle a bit more backward. - Simultaneously, since the
brake pad 32 is given a force upward, theprotrusion 34 is contacted to thewheel 20, which extends to the front end of thebrake pad 32 and is spaced from thewheel 20 at a predetermined distance. Consequently, a secondary brake function is performed. - At this time, although the
protrusion 34 and thebrake pad 32 extend to each other, it is preferable that they are made of a different kind of material and theprotrusion 34 has a larger friction coefficient and a larger tensile strength. - If the
brake pad 32 is worn down because the user often operates the brake function using thebrake pad 32, thebrake pad 32 can be drawn out through the opening formed at the front end of thecoupling groove 36 and anotherbrake pad 32 can be mounted thereto. - While the invention has been particularly described and illustrated with reference to a preferred embodiment, it will be understood by those skilled in the art that changes in the description or illustrations may be made with respect to form or detail without departing from the spirit and scope of the invention.
- As described above, the roller shoe having the brake pad according to the present invention can perform the brake function smoothly by inserting and mounting a brake pad with a large friction coefficient and tensile strength on the rear end portion of the wheel mounted on the sole. Also, by forming the protrusion on the front end of the brake pad so as to be extended thereto and spaced apart from the wheel at a predetermined distance, the rotational force of the wheel is reduced upon a friction between the brake pad and the pad for thereby allowing the user to ride the roller shoe safely.
