Definitions

  • the main object of this invention is to provide an improved roller-skate of the said type which will allow quick starts and sudden stops with out impairing a safe support for the user of the skate, and which will permit to attain high speed even in quick and sharp turns.
  • my improved roller skate comprises at least two auxiliary rollers and an intermediary main roller arranged in a single track the convex running surface of all rollers,
  • FIG. 1 is a plan view of my improved roller skate taken from underneath and showing a skate containing three rollers or wheels arranged in alignment,
  • Fig. 2 is an elevational view to Fig. l'partly in section
  • Fig. 3 illustrates diagrammatically cross section of the rollers in planes passing through their 1 axis of rotation while the plane of rotation of said rollers is perpendicular to the racing surface;
  • Fig. 4 which corresponds to Fig. 3, showsa different inclination of the plane of rotation of the rollers in respect to the racing surface
  • Fig. 5 is a section on the line 5-5 in Fig. 2
  • Fig. 6 is a similar section of another embodiment
  • Fig. 7 is a side view showing the rear part of and Figs. 8 and 9 show in cross section-and in partial side view, respectively, still another embodiment of the rollers used in my improve skates. r
  • the frame I of the skate is provided with suitable foot plates 2, 3.
  • Three rollers or wheels 4, 5, 6 are mounted pref-' erablyupon ball bearings in the frame I behind each other in the direction of racing. Said rollers are of different size and have differently shapedv running surfaces clearly appearing from' a roller skate in the embodiment shown in Fig. 6,
  • IV indicates the running surface of" roller 4, V the running surface of roller 5 and VI that of roller 6.
  • V the running surface of roller 5
  • VI the running surface of roller 6.
  • the running surface IV, V, VI of all rollers 4, 5, 6 contact the course surface P.
  • the differently shaped running surfaces IV and VI of the auxiliary rollers 4 and 6 will one by one disengage from the racing surface P until only the surface V of main roller 5 remains in contact with the racing surface P.
  • the main roller 5 has the largest diameter and its running surface V has a spherical shape.
  • . preferably is made from a light metal is mounted.
  • the front auxiliary roller 4 has the: shape of a narrow wheel with an elastic tire. At. the front end of the adequately stiifened frame: I a suitable jump 01f abutment I1 is provided in; the shape of a screwed-in plug made of rubber: or similar material.
  • Fig. 6 shows a somewhat modified arrangetherein by suitable attachment rings. Said ball.
  • bearing supports the complementary halves 1.. II of the roller which parts are connected by a bolt l3.
  • the web 14 extends rearwards in a braking spur l6 as shown in Fig. 7.
  • the racing course P tending to guide the skate in a straight direction.
  • the skate resting with all three rollers upon the race course has a considerable stability, as there is no possibility of easy tipping forwards or rearwards. If, however. the skate is inclined laterally, into the position shown inFig'. 4, only the main roller (running surface V) remains finally engaged with the course surgaged therefrom? The entire load is then resting on the main roller 5 of spherical shape which offers to any change of the racing direction a far smaller resistance than a set of two or more rollers arranged behind each other and uniformly loaded. Therefore the disclosed arrangement according to the invention allows racing in curves of even small radius simply by a rolling movement of the main roller eliminating any skidding and undesirable friction of the auxilriary rollers.
  • the spherical shape of' the running surface V of themain roller is particularly suitablebecause it guarantees a" permanently uniform en'- gagement with the racing course surface P at any angleof' inclination o" and a maximum stability in transverse direction.
  • The-basic idea of thepresent invention may, however; be carried" intoeife'ct' with other suitable'shapesof the main roller- 5; if only the selected shape matches the profiles of the auxiliary rollers. 44" and 6" in such manner-that the said, auxiliary bodies 4'; 6. are. at certain inclinations of the'plane'SSi'of rotation lifted out of. engagement. with thecourse surface P.
  • the main roller ⁇ alf has the largest diameter din order to reduce to a minimum the losses duringthe race upon this utmost loaded body;
  • Fig. 8 which shows still, another embodi.- ment of the present invention, 24 is the frame of a roller skate wherein by means of apivot .23. and ball bearings 22 a metallic roller 21' is. ro-
  • being provided with a rubber lining 25..
  • border discs 26 of a hardsteel plate. with a sharp outer edge 2 are attached thereto. by rivets 28, said edge 2.! being. approximately at the same level asthe. surface of the-rubber lining. 25.
  • the roller according to the .present invention which may also be of any other suitable profile than that illustrated thus combines in itself the necessary features ensuring an elastical racing, as Well as the possibility of an efiective engagement for jumping off and braking, and an outstanding durability.
  • is laterally provided with hard discs 29 having a circumferential teething 30 to enable a still sharper-engagement;
  • some of therollers may also be provided with aone-way free motion preventing any backward rotation so that the respective roller maybe used as a jump off.
  • roller skates according to-this'invention are; asfar as speediness, possibility of racing in sharp curves, safety of control and fitness for figure-skating, and hockey competitions is concerned, fully equivalent to edge-skates which are suitableonly for ice courses.
  • a...roller skate comprising in combination a' supporting'frame, at least two auxiliary rollers and anintermediate main roller in. tandem formation, fixedaxles for said rollers mountedin said frame, each ofsaidrollers having a transverse convex running surface contacting .,the supporting surface while. the rollers rotate in a plane essentially perpendicular to the supporting surface, the convex running surface of the. main .rollerhaving a greater radius of curvaturethan the running surfaces of the. auxiliary rollers.
