Definitions

  • MICHAEL sKoRKA or BUDAPEST, HUNGARY.
  • roller skatel for its object to provide such a roller, skatel witha peculiar elastic supporting means tot' the rollers, of the total number of which only .one group of adjacent rollers is'operal tive at a time, according to the position of the body or foot on the skater, whereby the roller skate is givenA a quick, smooth and yet 4surel action, similar to that 'of an ordinary skate for use on the ice and the l@ transition from roller to roller takes place without any jerk, the front and back roller being provided with automatically acting brakes, so that all movements and exercises that are possible with ordinary skates can E@ be performed with the new roller skate.v
  • roller' axles are not journalled asv heretofore rigidly in two parallel rigid longitudinal members on the frame of the skate, but in separate bearings which are fixed to the underside of each of two Hat longitudinal springs'which are located on either side of the rollers, are freely supported between each two bearings and are capable of moving inl their longitudinal direction.
  • the endsi/of these longitudinal springs supporting the front and rear rollers ⁇ are unsupported and when pressure is brought to bear on the front or the rear roller, for the purpose of reducing speed or coming to a standstill, bend so ar upward that the roller comes in contact with.
  • roller skate frame consisting subf stantially of two parallel longitudinal girders 3 of U-shaped profile open to the top, which are connected together at the front and at the rear ends by means oi' the sole plates 1 ⁇ 'l"(lTigs. 2 and 3) and have lateral flanges 2, by means of which they can be screwed to the sole and heel of the boot,
  • the bottom sides of the two longitudinal girders 3 have corresponding transverse arched projections 4t, 'to which the two fiat longitudinal springs 5 70 supportingthe roller bearings are attached parallel to one another yin such a manner by means ot screws 6 having heads that at the places of attachment they are free to bend and are capable of moving in the longitudinal direction in accordance with their bending movements, 1F01' this purpose the: springs 5 are each rigidly ixed against longitudinal movement only at one point ci Y attachment, while at all the other points of S0 attachment they have slots l (lEig. 5)
  • the springs ⁇ 5 are so designed that two to three. adjacent sections of the same and consequently two to three rollers will su'llice for supporting the weight of the skater without 1095 any undue bending of the springs.
  • a single group of two ⁇ to three rollers lying 5 ranged aloncr immediately one behind the other is stressed corresponding to the position at any time rf the body orV foot of the skater.
  • the springs -5 may'A each be'formed of one lat spring oi suitable thickness extending the entire lengt-hof the skate, but preferably of two *ci*fp more superposed thinner flat springs. In either ease the unsupported end portions of the springs must be suit- 40 ably reinforced, as is indicated 'in Fig. 1. For the better transmission of the weight of the body-and its reactions to the springs 5 and for securing the screws for fixing the springs 5to the frame of the skate and the roller bearings 8 to the springs, short pieces 13 and 14 of flat spring are interposed above.
  • a roller skate comprising in-combina- .8 tion a frame, two rows of downwardly extending projections on the frame; two parallel longitudinal flat springs attached to the said two lrows of projections so a's to be capable of movingfreel and to extend *atr .the 'front and back en s of the skate beyond the foremost and backmost projecy tions, roller bearings xed rigidly to the 'said springs between the points of attachment ofeach spring and so-as to project 9 downwards and skate rollers on the saidC roller bearings, the foremost and backmost skate roller bearings being fixed on the unsupported forward -and backward extensions of the longitudinalA springs, as and for the 95 purpose set forth.l rf
  • nal springs to the projections effected by Square-headed screws and the fixing ofthe bearings to the longitudinal springs by s nare-headed bolts and having short pieces o flat spring inserted at the points of atf tachment of the longitudinal springs be- 110 tween 'the latter and the frane and extending almost to the square heads of the screws and other short pieces of nat spring inserted vbetween the longitudinal springs. andthe roller bearings and extending almost-to the -115 square heads ofthe bolts, whereby the screws and bolts are secured from turning and the effect of the longitudinal springs' is' enhanded, as set forth.
