Definitions

  • the present invention relates to a roller skate with self adjusting brakes, working on load-adjusting wheels, said brakes have progressive operating strokes ranging from slight- to full while blocking of the wheels will, under normal circumstances, not occur.
  • Said brakes can be divided over a number of wheels and can be operated simultaneously. Without interference from each other.
  • Braking in roller-skating is done either by; directly pushing a solid pad which is attached to the mainframe of the skate, at the ground and uses the dry friction between the skating surface and the block to reduce velocity. Or by increasing the roller resistance, by a contact on the perimeter of one of the wheels and uses the dry friction between roller and skating surface as a counter-force to reduce velocity.
  • Activating the brake is either done by rotating the foot, or pressing the heel down and extending the leg in the driving direction or by using a hand operated cable mechanism.
  • a hand-held device operates the brake pad, which is either attached to the back of the roller- skate or in between, its wheels.
  • the braking mechanism occupies the hands, while having the hands free is a very important demand in an agility sport like roller-skating.
  • the braking-pad increases the overall length of the skate, it wears very fast and it leaves marks on the skating surface. Driving on uneven surfaces, especially the ones with crevices, the brake can hook-up itself up and in any case will behave very unpredictable. Examples of previously known wheel-braking devices, with direct hand- or remote controlled devices of this kind is known from
  • EP 486 013 Al Whether the brake is controlled directly by hand or remote in either case the brake occupies one or two hands, while having the hands free is a very important demand in an agility sport such as roller skiing or -skating. Furthermore is ground contact of the rollers, on which to brake, in this construction only possible, when no more than two wheels are used in the entire construction. The whole brake operation system is bulky and prone to tangling up. Furthermore it is difficult to define a proportional growing brake-force against a fixed point, especially to control the force up to a point where skidding or blocking of the rollers will not occur.
  • a foot controlled braking pad is known from - US 5,649,715.
  • the braking pad will wear very fast, leave marks on the skating surface and the braking angle increases in relation to the wear of the braking pad.
  • the brake increases the length of the skate, the skating rollers- ahead of the roller, around which the skate rotates, will have to leave the ground and will make it difficult to keep the direction of motion. Again driving on uneven surfaces, especially the ones with crevices, will result in hooking up of the brake or at least an unpredictable behaviour of it .
  • Examples of a foot controlled anti-lock brake roller is known from - US 5,088,748.
  • the wheel instrumental in braking increases the length of the skate in comparison to the effectively needed length.
  • the braking force is related to a given pre- set angle and pressure without factual relation to the dry-friction load ratio in the actual user condition and the therewith connected increase in brake-force (dry-friction increases in direct relation to load) .
  • the wheels in front of the wheel, around which the skate has to be manoeuvred in order to come to the braking position have to leave the ground surface influencing the manoeuvrability and stability of the movement. Furthermore it is claimed in this invention, that the brake does not lock.
  • Examples of a foot controlled brake on a roller skate wheel is known from EP 379 906 A2.
  • the wheel instrumental in braking is placed on the last wheel, it hinges around the axle of the wheel directly in front. Around said axle the skate is also pivoted to come to the braking position, leading to a complicated and bulky construction on the backside of the skate, increasing the length nearly as much as an extra wheel would.
  • the wheels of the in-line skate are fixed with the exemption of the last wheel . During use said wheels wear differently and have each different ground contact.
  • Example of a foot controlled brake on a roller skate wheel is known from EP 0 677 310 Al .
  • the restrictions on this design coincide with the foregoing example.
  • a serious degradation of the braking function will occur, when the last and fourth wheel is lifted on an uneven part and the third wheel looses ground contact. This will occur frequently on uneven surfaces like rough asphalt, splits in pavement etc .
  • Example of a foot controlled brake on a roller skate is known from UK 2 160 780 A. Pivoting the frame and a brake pad against the last wheel; the control of not creating a roller resistance in excess of the ground dry friction of the wheel at a solid brake point is very difficult, while the whole functions only on a skate with two wheels. While oscillations created between surface and roller, will make the functioning of the brake haphazardly.
  • Example of a lower leg controlled brake on roller-skates is known from US 5,649,715 A.
  • the braking is done on a pad, operated by rotating the lower leg, together with the top-part of a boot around the bottom part and uses this motion to push a pad down over a hinge.
  • the number of patents using this motion is staggering, therefore we have chosen a recent one. They all have in common that the aft part of the roller skate can be lift of the ground by the leverage between shoe and roller-skates. Remaining is also the fact that skating on not even surfaces will produce oscillation between the parts and it will be easy to hook up the brake on sharp unevenness . Again the brake pad will wear fast and leaves markings on the surface.
  • Examples of brakes using the side of the wheels is known from UK 2 002 243 A.
  • the braking is done pivoting to the roller plane around a hinge and uses the displacement around the hinge point to press two braking pads against the sides of two adjacent wheels.
  • the construction is too and the regulation of the braking force is hard to control because of the oscillations created between rollers and skating surface.
  • the purpose of the invention is a brake system for the various types of roller skates, -skis and -skate boards and emphasising in-line roller skates.
  • the brake - functions on uneven surfaces, - does not lengthen the size of skate, - can be regulated under a brake stroke, - is self regulating, -has comprehensive indicators on wear, - has equalisers regulating the brake itself as well, as on a number of wheels, - is operated by a foot movement, remaining practically identical during, the standard brake life.
  • the main objective is to create a safer use of roller skates.
  • the present invention is encompassing a mainframe, in which a number of wheel casings are pivotal mounted. To said wheel casings, tensioning devices are attached. Said wheel casings are over said tensioning devices connected to said mainframe via flexible, permanent elastic springs. Said springs are produced in a comprehensive range, which makes it possible to adapt each pair of skates to the individual in terms of body weight as well as skating technique and velocity. Said springs act as load dividers and make sure that all wheels have road contact, so that braking action is always possible on a given number of the wheels. To the wheel casings are disc brakes mounted centric with the diameter of each wheel.
  • Said disc brakes can be forced against the side of said wheels, by rotating a disc-operating ring and the disc-brake around one another, resulting in a controlled increase of roller resistance on/of the wheel.
  • an equaliser is attached to the rotating brake half in order to disperse the brake force evenly over the wheels and to compensate for and indicate wear.

  • the embodiments hereafter described show a roller skate with a foot or lower leg operated self-adjusting brake and load adjustment of the wheels 2,3,15,16 in order to keep contact with the ground at uneven surfaces.
  • the roller skate is mounted to a shoe 100,109, and fig. 1-2 is showing a three-dimensional picture in which a front wheel is arranged to be rigidly attached to a main frame 1 in order to keep motion direction, while the following wheels 3,15,16 are arranged to be located in pivoted wheel casings 4.
  • Disc brakes 11 and permanent elastic springs 7 are attached to these wheel casings 4.
  • equalisers 12 are installed in order to operate the disc brakes 11.
  • the main frame 1 has a pivot connection to the shoe over a base plate 29 or is directly mounted to the shoe.
  • the base plate is incorporated with the shoe .
  • Fig. 1 shows a three dimensional view of the roller skate without the actual first wheel 2, the second wheel 3, the third wheel 15 and the last wheel 16 (see fig.3), the base plate 29, which is preferably incorporated in the sole of shoe 100 (see fig. 3), is connected pivotally to the main frame 1 over a hinge 30. At the front the base plate 29 is connected to the main frame 1 over a hinge mechanism 14. The base plate 29 can now rotate in the main frame 1, and can while doing so move a pinion
  • the pinion 22 holds a central brake lever 13 (see fig. 3) and moves this backwards when the base plate 29 is rotated in the main frame 1.
  • lever 13 On lever 13 are installed three pins 42 to which the topside 23 of the equalisers 12 are installed.
  • a pinion 21 is installed on lever 13, which pinion 21 fits in a slot 27 in the main frame 1 and the stroke of lever 13 is thus limited to the size of the slot 27.
  • a permanent elastic spring 20 is installed in such a way that when lever 13 is continuously pressed forward, said continuous pressure works on pinion 22 (see fig. 3) of the hinge mechanism 14 and presses shoe 100 with base plate 29 continuously against the main frame.
  • the first wheel 2 (see fig.
  • the second wheel 3 is connected to the main frame via the wheel casings 4 with the halves 43 and 44.
  • the wheel casings 4 are connected pivotal to the mainframe 1 over a hinge screw 5.
  • On the top of the wheel casings 4 a pinion 10 is installed, engaging the permanent elastic spring 7.
  • the permanent elastic spring 7 is pre-stressed between a pin 8 and a pin 9, which pins are installed on the main frame 1.
  • the pre-stress is necessary to compensate for the initial load, related to body weight, technique and velocity of the skater, which vector-force will work at 101,106 and 107 (see fig. 3) .
  • the disc brakes 11 installed around the centre of the wheels 3, 15 and 16 are on a left half 45 of the wheel casing. To avoid the disc brakes 11 from rotating and being installed wrong, they have a hexagonal oneway fit 57 on the left half of the wheel casing 45 (see fig. 8) .
  • the disc brakes 11 can be moved to come in contact with the sides 26 of the wheels, by rotating a ring 34 (see fig. 6)
  • the equalisers 12 are installed between the pins 42 on lever 13 and the pins 47 on the brake operating ring 34.
  • the equalisers 12 When the lever 13 is moved backwards the equalisers 12 will at first follow as a whole, rotating the brake operating ring 34 in an affiliated motion. Once contact at said side 26 is established only the top part 23 will continue to move, thereby compressing a spring 39 in the equaliser (see fig. 7) . The compression of the spring 39 will result in an increasing pressure of disc brakes 11 towards the wheel sides 26 and thereby creating a proportional growing friction between the wheel sides 26 and the disc brake 11 and subsequently higher roller resistance.
  • the initial rotation of ring 34, in order to move the disc brake 11 against the surface 26 can be different for the wheels 3, 15 and 16 and depends on how far the braking surface 26 is worn.
  • the aforementioned different distances do hardly influence the braking capacity, while the continuation of the braking stroke, by compressing said springs 39, will give a proportional brake stroke.
  • the wheels 3, 15 and 16 have a load adjustment, in order to have always all wheels at the skating surface when braking, The load adjustment does not interfere with the brake function.
  • a load at for example the ground surface 101 becomes higher, the moment of force between 101 and hinge 5 increases.
  • the counter moment of force between hinge 5 and spring 7 at point 10 will have to increase in conformity. It will do so by stretching spring 7 between pin 9 and pinion 10 and thus increase the force on pinion 10. Because of the said stretching of spring 7 the wheel 2, receiving the higher load will move upward, to the given point thereby dividing the general load again relatively over all the wheel surfaces at 101-106-107 and 108 and visa versa.
  • Fig. 2 shows a three-dimensional view of a second embodiment of the roller skate with removed wheels.
  • the main frame 59 is directly mounted to a boot half 109 (see fig. 16) .
  • a hinge mechanism 60 on the backside of the shoe now operates the central brake lever 13 (see fig. 16 and 17) to move in the same way as in the previous described embodiment , i.e. a longitudinal motion of a force transmitting member, in these embodiments arranged as a rigid central brake lever 13 , forces a brake operating ring 34 to rotate and thereby axially force a disc brake 11 towards the side 26 of a roller skate wheel 3,15,16 when the skater changes the foot or leg angle towards the skating surface.
  • the force transmitting member can be a flexible member, such as a cable.
  • Fig. 3 shows the roller skate of Fig. 1 with the wheels 2, 3, 15 and 16 in place and in contact with an uneven surface 104.
  • the first wheel 2 has contact with the ground over main frame 1, shoe 100 with base plate 29 and ankle 102. Said contact is necessary to keep the direction of motion under control, while at the same time the ability of vibration insulation between the parts is optimal.
  • the second wheel 3 and its wheel casing 4 have pivoted around hinge 5 to its maximum within main frame 1. Representing a situation in which roller skating of the kind described would be impossible, providing the interference would repeat at a more than regular frequency.
  • the third wheel 15 and its wheel casing 4 have pivoted around hinge 5 half the available distance. While the fourth wheel 16 has remained in neutral position.
  • wheel 2, 3, 15 and 16 represent a practical situation and representing a dynamic equilibrium, changing instantly with the general operating conditions.
  • the wheels 2, 3, 15 and 16 have all contact with the surface and are in a position where braking on the wheels will give the requested counter force from the dry friction the wheels have on the surface 104.
  • Fig. 2 also shows the shoe 100 with the base plate 29 and the location of hinge 30. At hinge 30 the main frame 1 can pivot in respect to the base plate 29.
  • the wheel casing 4 of the fourth wheel 16 is in its neutral position. Indicating that the pre-tensioning of spring 7, between the pins 8 and 9 is equal or lower than the result of the moment of force between hinge 5 and reaction force 106 on pinion 10 of wheel casing 4.
  • the equaliser 12 is suspended between a pin 47 of the brake operating ring 34 (see fig.9) and pin 42 on lever 13 and is not exposed to a force between the pins 42 and 47.
  • the wheel casing 4 of the third wheel 15 has pivoted under influence of the reaction force 107. Indicating that the result of the moment of force between hinge 5 and the reaction force 107 exceeds the pre-tension of spring 7 between the pins 8 and 9. Causing the pinion 10 on wheel casing 4 to move forward and tension spring 7 to such an extent that it equals the result of the moment of force between hinge 5 and reaction force 107 on pinion 10.
  • the pin 47 on the brake operating ring 34 will have rotated together with wheel casing 4 around hinge 5. Taking with it the bottom side of equaliser 12.
  • the equaliser 12 rotates around pin 42 and becomes a little shorter. The change in length will not result in a force between the pins 42 and 47 because of the compensation space 41 within the equaliser 12. (See fig. 6)
  • the wheel casing 4 of the second wheel 3 has pivoted under the influence of reaction force 101. Indicating that the result of the moment of force between hinge 5 and reaction force 101 exceeds the pre-tension of the spring 7 between the pins 8 and 9. Causing the pinion 10 on wheel casing 4 to move forward and tension spring 7 to such an extent that it equals the result of the moment of force between hinge 5 and reaction force 101 on pinion 10.
  • the pin 47 on brake operating ring 34 will have rotated together with the wheel casing 4 around hinge 5. Taking with it the bottom part of the equaliser
  • lever 13 will always be pushed forward and will exert pressure on hinge pinion 22 and keep the shoe 100 and base plate 29 in contact with main frame 1.
  • the springs 7 and 20 are secure locked in place by a spring clip 17.
  • the springs 7 and 20 are located on the outside of the main frame and can be exchanged easily, making it possible to adapt the bearing- and braking capacity of the skate to the individual.
  • the wheels In rigid in-line roller skates the wheels have all the same diameters, in order to create an even wear and thereby all-over ground contact on all the wheels. In the design at hand wear on the perimeter of the wheel is compensated for, thereby it becomes possible to fit the diameter of the wheels within the anatomical lines of the foot. The diameter of the last wheel can therefore be increased compared to the front wheels, without moving the foot upwards . The increased diameter of the wheel will result in a lower roller-resistance increasing the dry friction and consequently brake capacity.
  • Fig. 3 shows the roller skate when the braking mechanism is fully deployed, in this situation the lever 13 and pinion 22 are moved backwards from its original position symbolised by A to its position B.
  • the topside 23 of the individual equaliser has moved and rotated around the pins 47, in coherence with said slight rotation and in relation to the movement from A to B .
  • Said vertical displacement has no influence on the whole other than a vertical enlargement of the slots 24 in the main frame.
  • the ground surface has a not flat profile and that the wheels act all at the different levels.
  • the wheel 2 is fixed in the frame and has no brake, in order to maintain steering capacity.
  • the side 26 of wheel 3 is more worn, than the ones on wheel 15 and
  • a test, to check the actual brake condition, will be to place the foot holding the skate on the knee of the other leg and draw at the front of the skate, in order to imitate the brake movement.
  • the opening remaining at either C or C2 will give a direct indication of the braking capability left.
  • the distance as is represented in C is considered -maximum wear-, a mark 56 (see fig.7) on the centre shaft 27 of the equaliser 12 indicates that the wheel has to be turned or exchanged.
  • Fig. 4 shows also the base plate 29 which is, preferably, integrated with shoe 100 and hinge 30 which connects base plate 29 pivotally on main frame 1.
  • the front of the base plate 29 connects pivotally at a pinion 51 to a lever 52 of the frontal hinge 14.
  • Lever 52 connects at pinion 22 with a bottom lever 53 of hinge 14.
  • Lever 53 is pivotally connected to the mainframe 1 at a pinion 54.
  • the pinion 22 circulates around a pinion 51 and the pinion 54 simultaneously when the shoe 100 and base plate 29 are rotated around hinge 30, the rotation of the shoe being limited within the slot 27 of the main frame.
  • the configuration has the following targets; the mainframe 1 and base plate 29 have to be perfectly in line with each other; the mainframe and base plate 29 have always to be pressed against one another; to initiate braking an initial force is required; braking can be done gradually over an on-going movement of the foot.
  • Fig. 5 shows a bottom view of the device shown in fig.l with the second wheel removed in order to show the outlines of hinge 14 bearings in place. It shows the, - base plate 29 and central lever 13, - halves 43 and 44 of the main frame, - levers 52 and 53 of the frontal hinge mechanism 14 and the fixing points at the hinge 5, at a front wheel bolt 6 and at the base plate hinge 30 which keep the construction together.

  • Fig. 6 shows a sectional view over the centre of the fourth wheel 16 of a device as shown in Fig. 1 and 3, with the equaliser 12 removed. Said view is representative for the other wheels equipped with brakes . Shown is a bearing for a wheel axle comprising a screw member 103 and a nut member 105 which bearing has a limited and predictable axial clearance and has the capacity to accept the thrust forces generated by the disc brake
  • the friction between disc brake 11 and the wheel side 26 can be kept low and the maximum brake output is chosen to be lower than the dry friction of the wheel on a standard surface. Practically this means that the brake surface of disc brake 11 is quite smooth and never will need replacing. At the same time will the abrasion of the wheel side 26 be very low. It is a given fact that brake capabilities coincide with the roller skate capacity in general. Which indicates that the number of wheels and their respective diameter dictates the attainable speed at the cost of flexibility etc. In the design at hand the brake capacity grows with the number of wheels and their respective diameter. Furthermore is shown on fig. 6, a seal 36 to avoid dust entering and impairing the functioning of the inter-relation of the disc 11 and the ring 34. Also a left half 45 of the wheel casing is shown in fig. 6.

  • the equaliser rotates simultaneously between pin 42 and 47 when the wheel casing is rotated at hinge 5. The length alteration during said simultaneous rotation is accepted at slack 41. It is understood that when lever 13 is moved backwards, the disc 11 will approach the side of the wheel 26 (see fig. 6) . As soon as disc 11 abuts the surface 26 of the wheel, the spring 39 will start to compress drawing with its compression force at 40 and increasing by its compression the force exerted to the surface between the wheel side 26 and the disc-brake 11 (see fig. 6) .

Abstract

Cette invention concerne un frein pour un patin à roulettes comprenant un cadre principal (1, 59) qui assure l'interconnexion entre une plaque de base/charnière (29/30) et une chaussure (100) ou une demi-botte (109). On actionne un levier (13) sur les charnières (14, 60), lequel levier est connecté à au moins un égaliseur (12) actionnant un disque. Un anneau d'actionnement (34) permet de pousser un frein à disque (11) contre la surface (26) d'une roue. Au moins une console (4) des roues est montée pivotante sur une vis de pivot (5) du cadre principal (1). Ce système permet d'accroître la résistance du patin sur les roues (3, 15, 16) et d'obtenir une action de freinage progressive et fluide.
