Definitions

  • the present invention belongs to the field of sports/games/recreation, and in the scope thereof it relates to skateboards, particularly the ones which provide special, integrated measures for physically driving the skateboard. ( Int. Cl. 4: A 63 C 17/12, B 62 M 1/08)
  • a skateboard In a primary configuration of a skateboard the latter comprises an elongated, suitably designed footboard to which two pairs of rollers are suspended from below.
  • a skateboard can further comprise supplementary equipment, e.g. a brake, a flywheel, a lamp, a marker, a buffer, etc.).
  • supplementary equipment e.g. a brake, a flywheel, a lamp, a marker, a buffer, etc.
  • This action can be realized by means of specific suspension of the rollers, and at performing a curve the inclination of the footboard results in that a front and a rear roller, the “inner” rollers with respect to the curve, are mutually approached, whereas the other two rollers, the “outer” ones with respect to the curve, are mutually drawn apart.
  • skateboard/rider-system as a physical phenomenon, i.e. at skateboard and rider functionally united into a combined, independent unit, can be discussed merely within the period of the consumption of mass forces previously accumulated (or - in the case of riding downhill: by using the gravity force).
  • the pedal section is by means of linkages comprising a push rod, a crankshaft and a toothed segment, as well as by means of a gear train bound to said toothed segment and comprising four pairs of toothed wheels and a termination toothed wheel, which is bound to a roller shaft of the rear skateboard rollers, motion-transferably interconnected with respective skateboard rollers, each of the latter being connected to the shaft by means of an overrunning clutch.
  • the skateboard essentially provides the same height as the skateboards without propelling gearings, and there are aimed to be retained diverse operational possibilities, such as ease in negotiating curves and maneuverability.
  • the height of the skateboard can only be a matter of discussion in connection with the front, i.e. fixed, footboard section of the skateboard, not in connection with the rear, i.e. pedal section, except at a position when its pedal function is arrested which, however, is not in conformity with the primary aim or object of the solution.
  • the invention is based on the problem how to convert said swinging of the footboard to propelling of the rollers of a skateboard.
  • the amplitude of swinging which, preferably, is as small as possible, and the frequency of swinging which, preferably, is as high as possible, are mutually coordinated so that swinging does not result in a noticeable inconvenient meandering of the skateboard.
  • a skateboard for realizing the method defined above and comprising a train-type interconnection between the footboard of the skateboard ad a roller shaft of the skateboard, whereby each roller of the skateboard is with a respective roller shaft connected indirectly by means of an overrunning clutch, is in a basic design characterized in that to a socket shaft housing of a suspension, said housing encasing said roller shaft, there is to each end thereof attached a gearing.
  • skateboard of the same type characterized in that to a socket shaft housing of either suspensions, said housing encasing said roller shaft, there is to each end thereof attached a gearing.
  • each gearing is composed of:
  • the skateboard comprises a footboard 1 which is composed and designed in accordance with the respective object and on whose lower side a front substructure assembly 2 and a rear substructure assembly 3 are suspended at the front and the rear end sections, respectively.
  • the connection of the footboard 1 and the substructure assemblies 2, 3 is a direct one, similar to that at the skateboards without incorporated driving gearings.
  • the substructure assembly 2, 3 is designed by a two-column suspension 4 (front); suspension 5 (rear) which, as such, belongs to the prior art
  • the two suspensions 4, 5 constructionally equal each other, yet are arranged in known manner mirror-symmetrically with respect to a vertical central plane positioned transversely to the direction of the movement of the skateboard.
  • the constructional feature just mentioned appears such that of the two-column suspension 4 of the front substructure assembly 2 a rigid, internally rotatable and breakable column 6, and of the two-column suspension 5 of the rear substructure assembly 3, respectively, an elastically flexible column 7 is visible.
  • the columns 6, 7 of either suspension 4, 5 are arranged in a V -relation in the central longitudinal vertical plane of the skateboard, which feature in the combination with other features of the suspensions 4,5 makes it possible that at tilting of the footboard 1 to the left or to the right, respectively, with regard to the direction of riding the skateboard, the front substructure assembly 2 and the rear substructure assembly 3 are definitely swung in opposite directions - each assembly around its own vertical axis, which coincides with the axis of the rigid column 6, which shiftings in functional meaning result in turning of the skateboard.
  • the front substructure assembly 2 and the rear substructure assembly 3 constructionally equal each other.
  • the front substructure assembly 2 and the front suspension 4 will hereinafter be referred to, but including the rear substructure assembly 3 and the rear suspension 5.
  • a roller shaft 11, bearing at its free end sections skateboard rollers 12, is inserted through the shaft housing 8 and the gearings 9,10.
  • the gearing 9 is composed of a box-shaped mounting casing 13 which is attached to the free end of the shaft housing 8 and in which, beside the roller shaft 11, a shaft 14 for carrying gears, conveniently disposed above the roller shaft 11, and an intermediate shaft 15 also for carrying gears, disposed by height between the shafts 11 and 14, but shifted rearwards with respect to the direction of riding the skateboard, are mounted.
  • the mounting casing 13 On the side oriented to the roller 12 of the skateboard, the mounting casing 13 is closed by a vertical adapted wall 16 (please also cf. Fig. 6).
  • a mounting cover 17 which provides another series of bearings for pivoting the shafts 11, 14, 15. In the ceiling part of the wall of the mounting cover 17 there is directly at the wall 16 foreseen a recess 18 for conveying a toothed rack 19 as explained below.
  • the pinion 20 resides inside the mounting cover 17 and projects into an appropriate circular recess 26 of the wall 16
  • the gear 21 accompanied with its overrunning clutch 22 resides inside the mounting casing 13 and is arranged at an axial distance from the journal of the shaft 14.
  • the intermediate shaft 15 supports a gear 23 designed to mate the gear 21, whose diameter is greater than that of the former one, and on the side oriented to the vertical wall part of the mounting casing 13, supports a further, larger gear 24.
  • the two gears 23, 24 are directly connected to the intermediate shaft 15.
  • the roller shaft 11 supports a gear 25, driven and designed to mate the gear 24, whose diameter is larger than that of the former one.
  • the interconnection of the gear 25 and the shaft 11 is a direct one as well.
  • the wall 16 provides an upright trough-shaped guide 27 (Fig. 6) for the accommodation and guiding of the upright toothed rack 19, the inner cross-section of the guide 27 coinciding with the recess 18.
  • the gearing is designed on the principle that one stroke of the toothed rack 19 results in one revolution of the shaft 14. Naturally, at a complete revolution of the shaft 14 the windings of the spring 14 do not thoroughly clamp the mantle surface of the latter, and the ability of springness-accumulation of the spring is thereby not thoroughly exhausted.
  • the interconnection of the shaft 11 and the roller 12 is taken from prior art and designed by providing a roller bearing 29 (Fig. 3) and an overrunning clutch 30.
  • overrunning clutch 30 belonging to the roller 12 there is with respect to the overrunning clutch 30 belonging to the roller 12, as well as with respect to the overrunning clutch 22 which belongs to the gear 21, among known overrunning clutches chosen the one designed on two mutually movable rings inserted one into another and each of them carrying an appropriate series of roller needles, whereby the inclination sections are foreseen in the outer ring (a patent to TORRINGTON company).
  • the two overunning clutches 22 of rollers 12 bound to a common shaft 11 thus work in the same direction of rotation.
  • Figs. 1 through 6 of the drawing represent a state of a skateboard which is neutral with respect to the footboard 1 and is balanced with respect to the spring 28.
  • the four toothed racks 19 are forced upwards to the footboard 1 under the influence of the returning forces of the springs 28.
  • Fig. 7 schematically represents a state of a skateboard, which corresponds to a footboard 1 tilted to one of two limiting positions by force
  • Fig. 8 representing a state corresponding to tilting thereof into another limiting position.
  • the two springs 28 referring to the toothed racks 19, which are pushed down by the footboard 1, are then tightened (stressed), the other ones are then slack (loose).
  • the states of Figs. 7-8 mean negotiation of curves by the skateboard to one or the other direction.
  • Fig. 7 comprises three plane coordinate systems bound to the swinging axis O of the footboard 1.
  • the x-y system denotes the position of the footboard 1 at riding straight, the x'-y' system denoting the position thereof at extreme turning to one direction (an analogous position as to extreme turning to the other direction being represented in Fig. 8), and the x''-y'' system denoting an optional intermediary position of turning the skateboard, i.e. slight turning.
  • Arched arrows A added to the ordinate planes y, y', y'' in Fig. 7 indicate the possibility of performing the swinging of the footboard with respect to the respective ordinate planes in the course of riding on a skateboard, with the amplitude of swinging each reasonably measured off.
  • skateboard By the skateboard according to the invention possibilities are given to start riding either by pushing off the ground (similarly to skateboards without a driving mechanism) or by treading on the footboard and starting swinging of the footboard of the skateboard.
  • the toothed rack of the gearing 10 belonging to the same roller shaft 11 follows the lifting of the footboard of the skateboard under the influence of the force of unwinding the respective spring.
  • the connection of the shaft 14 and the gear 21 of the gearing 10 is broken by means of the overrunning clutch.
  • overrunning clutches 30 are also necessary for riding a skateboard backwards, in that case without putting the driving gearings into gear.
  • each toothed rack 19 performs a motion (Fig. 8) composed of a straight, radial component R created by tilting the footboard 1 as such, i.e. swinging the footboard 1 around the longitudinal axis O , and also composed of a circular component C created at swinging the substructure assembly 2,3 to perform turning, i.e. at swinging around the vertical main axis of the suspension 4,5.
  • a motion Fig. 8
  • a straight, radial component R created by tilting the footboard 1 as such i.e. swinging the footboard 1 around the longitudinal axis O
  • a circular component C created at swinging the substructure assembly 2,3 to perform turning, i.e. at swinging around the vertical main axis of the suspension 4,5.
