Definitions

  • the present invention relates to roller skates, of which the wheel basis length can be changed during use, offering a short wheel base during situations where manoeuvring is required and a long wheel basis at higher linear speeds.
  • the operating characteristics of these roller skates closely resemble those of ice-hockey skates with curved edged skating blades.
  • the roller skate may be equipped with progressive working brakes .
  • Roller skates for agility sports, especially for roller-skating, are known for a long time, they require both speed and manoeuvrability during use.
  • the high speed to cross the field requires a long wheel basis, while the turning, twisting and positioning requires a short wheel basis .
  • the solutions used today are compromises, in which some of the required wheel basis length as well as some of the manoeuvrability is given up.
  • the object of the invention is to avail, to every roller skater and especially the roller hockey skater, the possibility, to change the length of the wheel basis, to the length most appropriate for the situation he/she is in. While turning, twisting or positioning a short wheel basis can be used. While when covering longer distances a long wheel basis can be used. A brake may be included. Thereby closely resembling the operational characteristics and possibilities one has with ice- hockey skates .
  • the present invention comprises a base plate, preferably direct attached to a skating shoe, to which a number of wheel casings are pivotally attached.
  • the said wheel casings are also attached to the base plate over permanent elastic springs. Said springs keeps/returns the wheel casings in position and acts as dampers. In said wheel casings wheels are rotationally attached.
  • a rotational movement of the foot or lower leg around the ankle makes it possible to alternate between; the wheels of all wheel casings in ground contact or the wheels of the front or the back wheel casing in ground contact, thereby availing the wheel basis concurrent to the motion.
  • a brake may be included.
  • Fig. 1 shows a three dimensional view of a roller skate with its wheels removed, with a flexible wheel basis length and damping.

  • a pre-tensioned spring 11 connects a pinion 8 fixed to the base plate 1, with a pinion 9 fixed to wheel casing 3 (See Fig. 2) .
  • the springs 10 and 11 are permanent elastic and form resistant, produced of a well vulcanised and stabilised rubber, EPDM saturated with peroxide and/or alternatives thereof. The springs have been pre-stressed and the initial elongation has been removed.
  • the third wheel 15a and the fourth wheel 15 have a bigger diameter than the first wheel 16a and the second wheel 16 and this is possible while following the outline of the under side of the foot and because the configuration guarantees continuous ground contact, even if the wheels wear differently (See Fig. 2) .
  • the wheel casings are connected by the hinge tube 18 (See Fig. 5) and by the axle bolts 14.
  • the bearings 17 can absorb radial as well as trust forces and the tightening of axle bolt 14 cannot seize them up.
  • the front and the rear hinges 18,19 are mounted by a rear axle screw 4 and a front axle screw 5.
  • Fig. 2 is showing the roller skate with the shoe 100 in a position representing the skating of longer distance.
  • Vector 111 indicates the resulting force of both motion energy and body mass working on the roller skate.
  • Vectors 109 and 110 signify the part of the force 111 transmitted to the permanent elastic cushions formed by the springs 10 and 11 between the base plate 1 and the pinions 6, 7, 8, 9 of the wheel casings 2 and 3 at the front buffer contact 12 and at the rear buffer contact 13.
  • the cushioning effect created by the springs 10 and 11 will result in a vibration insulation and shock damping effect.
  • Vectors 112 and 113 indicate the part of the force, indicated by the vector 111, directly delivered onto the hinge bolts mounted by the axle screws 4,5 of the wheel casings 2 and 3.
  • the resulting forces are represented by the vectors 105, 107 and 106, 108.
  • the vectors 101, 103 and 102, 104 indicate the reaction forces to the force indicated by vector ill.
  • the forces indicated by vectors 112 and 113 are divided over the wheels 16a, 15a and 16, 15 in an inverted relation to the lengths X - Y and Z - W.
  • part of the force 111 is dispersed over the surfaces of the springs 10 and 11 by the base plate 1 at the buffer contacts 12, 13 resulting in the buffer forces indicated by the vectors 109 and 110.
  • the forces indicated by the vectors 109 and 110 are divided over the wheels 16a, 15a and 16, 15 in an inverted relation to the lengths A - B and C - D.
  • the relation A/B is larger than relation C/D, resulting in a better vibration insulation to the second (front) wheel 16, which has a smaller diameter and a more secure road contact than the fourth wheel 15.
  • the third wheel 15a has because of its bigger diameter and mass all ready a higher vibration insulation and shock damping effect .
  • the total of forces and their leverage creates an even distribution of forces over all the wheels in the shown position.
  • this kind of skate is meant to be used on smooth surfaces, vibration insulation and shock absorption is given as well " as self adjustment of the wheel to uneven surfaces.
  • Each wheel casing 2 and 3 forms a steady triangle with at its base the wheels 16a, 16 and 15a, 15 and at its top the hinges 19 and 20, which are mounted to the same base plate 1. Unevenness of the skating surfaces will be absorbed either by; - base plate 1 rotating around the hinges 19 or 20, - wheel casings 2 and 3 rotating around the hinges 19 or 20, - base plate 1 and wheel casings 2 and 3 rotating simultaneously around the hinges 19 and 20. The rotation inward of wheel 16 and 15a will compress the cushion part of the springs 10 and 11 between the base plate 1 at the buffer contacts 12, 13 and the pinions 6, 9, and thereby increasing the forces indicated by the vectors 112, 113 and concentrating surface contact on the wheels 16 and 15a.
  • Fig. 3 shows the roller skate with either the foot rotated around the ankle 135 or the lower leg placed diagonally in the direction of force indicated by the vector 115. Resembling a situation in which a forward or backward curve will be made, while having the centre of gravity back.
  • the movement has caused the hinge 19 to lift, rotating the shoe 100 and the base plate 1 around the rear hinge 20.
  • Pinion 7, which is attached to the base plate 1, will also rotate along, taking with it the pre- tensioned spring 10.
  • Pinion 6, which is attached to the front wheel casing 3 will retain the spring 10 at buffer contact surface 13 under influence of the pre-tension of spring 10. Consequently the whole front wheel casing 3 and the therein attached wheels 16a and 15a will rotate together with the shoe 100 and the base plate 1 around the rear hinge 20.
  • Short and abrupt movements can be made by increasing the rotation around the rear hinge 20 of the base plate l, reducing the resulting force at 117 and increasing force indicated by the vector 116, to such an extend that the second wheel 16 can slide in an horizontal circle around the fourth wheel 15.
  • the increasing reaction force indicated by the vector 119 counter balances the growing movement of the mass force indicated by the vector 115 on the rear hinge 20 preventing toppling backwards. Since the counter force to be delivered by the spring 11 depends on body mass and driving style, it is important that it can be adapted to the individual .
  • Fig. 4 shows the roller skate with either the foot rotated around the ankle 135 or the lower leg placed diagonally in the direction of force indicated by the vector 121. Resembling a situation in which a forward or backward curve will be made, while having the centre of gravity fore.
  • the movement has caused the hinge rear 20 to lift, rotating the shoe 100 and the base plate 1 around the front hinge 19.
  • the pinion 8, which is attached to the base plate 1, will also rotate along.
  • the pinion 9, which is attached to the wheel casing 2 will retain the spring 11 at buffer surface contact 12 under influence of the pre-tension of the spring 11. Consequently the whole rear wheel casing 2 and the therein attached wheels 16 and 15 will rotate together with the shoe 100 and the base plate 1 around the front hinge 19.
  • Fig. 5 shows a sectional view taken along line I-I of Fig. 2. Shown are the two sides 3a and 3b of the wheel casing 3, they are firmly screwed together with a bolt/screw 4 and 5 onto hinge tube 18.
  • Hinge tube 18 is pivotally lodged in the base plate 1. There is a limited clearance between the sides of the wheel casing 2 and the base plate 1 and both are preferably treated with a low friction coating. Shown are also the bearings 17, at the two different levels, which are not prone to seizing up when the fasteners in the form of an axle bolt 14 are tightened, in order to make a steady casing.
  • the skate previously described can preferably be equipped with a brake in which a longitudinal motion of a force transmitting member via a spring, forces a brake operating ring (35) with a cam to rotate and thereby axially force a disc brake towards the side of a roller skate wheel when the skater changes the foot or leg angle towards the skating surface.
  • Fig. 6 shows an operating mechanism for a brake, which can be installed on one or all wheel casings 2 and 3.
