연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록
▼

A roller skate having enhanced durability and stability is disclosed. Furthermore, the roller skate is particularly adapted for affixing to a person's footwear, such as sneakers, boots or the like. The skate includes a platform for supporting a skater's foot. The platform includes a toe plate and heel plate connected by an adjustable connecting assembly. A front truck is affixed to the underside of the toe plate, while a rear truck is affixed to the underside of the heel plate. The front truck includes simple bracket arms for affixing a single front wheel which is capable of rotating, but not capable of tilting about the platform's longitudinal axis. Meanwhile, the rear wheel truck is mounted to the underside of the heel plate so as to permit both tilting movement about an inclined longitudinal axis, and also rotation about a transverse axis relative to the roller skate's platform. Preferably, the roller skate includes three wheels rotatably mounted to the rear wheel truck. A button projects upwardly from the roller skate's heel plate so as to engage a skater's heel when it is placed upon the roller skate's platform. The button is connected to the roller skate's connecting assembly so that depression of the button causes the platform to unlock from an extending condition to allow the skate to automatically contract to capture a skater's foot. Preferably, the skate's toe plates and heel plates include prongs for projecting into and affixing to a skater's shoe.

1. A roller skate and shoe combination comprising: a platform for supporting a skater's foot, said platform having a toe plate having an underside and a topside and a heel plate having an underside and a topside;a front wheel truck secured to said underside of said toe plate;at least one front wheel rotatably connected in transverse axial alignment on said front wheel truck;a rear wheel truck secured to said underside of said heel plate;at least one rear wheel rotatably connected in transverse axial alignment on said rear wheel truck:said platform including an adjustable connecting assembly for connecting said toe plate to said heel plate, said adjustable connecting assembly providing extension and retraction and a corresponding adjustable length of said platform to accommodate feet of different lengths;a toe prong having a proximal end and a distal end, said proximal end of said toe prong affixed to said toe plate with said toe prong projecting rearwardly above said toe plate;a heel prong having a proximal end and a distal end, said proximal end of said heel prong affixed to said heel plate with said heel prong projecting forwardly above said heel plate; anda shoe removably affixed to said toe plate and said heel plate, said shoe have a toe cavity sized and positioned for receiving said toe prong and a heel cavity sized and positioned for receiving said heel prong so as to affix said shoe to said skate, said shoe removable from said skate by extending the length of said platform to allow removal of said toe prong from said toe cavity and removal of said heel prong from said heel cavity, and said shoe affixable to said skate by retracting the length of said platform to project said toe prong into said toe cavity and project said heel prong into said heel cavity. 2. A roller skate and shoe combination as defined in claim 1 wherein: said skate comprises a plurality of toe prongs and heel prongs; andsaid shoe comprises a plurality of toe cavities sized and positioned for receiving said plurality of toe prongs and a plurality of heel cavities sized and positioned for receiving said plurality of heel prongs. 3. A roller skate and shoe combination as defined in claim 1 further comprising: a biasing means for biasing said platform into a retracted condition with said toe plate biased toward said heel plate;a locking assembly for locking said platform into an extended condition; anda button projecting upward from the topside of either said toe plate or said heel plate so as to engage and be depressed when a skater's foot is placed upon said platform; said button connected to said locking assembly so that depression of said button causes said locking assembly to unlock said platform from an extended condition to allow said biasing means to bias said platform toward a retracted condition. 4. A roller skate and shoe combination defined in claim 1 wherein said button projects upward from the topside of said heel plate so as to engage and be depressed when a skater's heel is placed upon said platform. 5. A roller skate and shoe combination as defined in claim 1 wherein: only a single front wheel is rotatably connected in transverse axial alignment on said front wheel truck; andthree rear wheels are rotatably connected in transverse axial alignment on said rear wheel truck so as to be in parallel axial alignment with said front wheel, said three rear wheels including a pair or rear wheels connected side-by-by side to form a rear wheel pair, and said three rear wheels includes a center rear wheel positioned rearward and between said rear wheel pair. 6. A roller skate and shoe combination as defined in claim 5 wherein: said rear wheel truck is connected to said platform for providing tilting movement of said three rear wheels about an inclined longitudinal axis relative to said platform; andsaid front wheel truck is connected to said platform so as to not provide for tilting movement of said single front wheel about a longitudinal axis relative to said platform. 7. A roller skate and shoe combination as defined in claim 1 wherein: said skate combination includes a pair of toe plates alternately removable and affixable to said front wheel truck and a pair of heel plates alternately removable and affixable to said rear wheel truck;said pair of toe plates includes a first toe plate which does not include toe prongs for projecting into said shoe toe cavities and a second toe plate which does include toe prongs for projecting into said shoe toe cavities; andsaid pair of heel plates includes a first heel plate which does not include heel prongs for projecting into said shoe heel cavities and a second toe plate which does include heel prongs for projecting into said shoe heel cavities.
