Definitions

  • This invention relates to new and useful improvements in base plate and truck assemblies for roller or ice skates.
  • the drawings and description refer primarily to the device when used for roller skates but it should be appreciated that it is easily adapted for use for the attachment of ice skate blades.
  • a sole plate which is screwed to the underside of the sole of a boot or shoe and has a pair of fixed wheel-carrying trucks secured to the underside of the plate together with a toe stop device also secured to the plate.
  • a sole plate assembly for use with a boot or shoe assembly which includes a sole member; said sole plate assembly comprising in combination a substantially planar plate having a heel portion, a sole portion and a shank portion therebetween, an elongated track extending substantially centrally along the under surface of said plate and being secured thereto and situated below the plane of the under surface of the plate, support surface engaging slider assemblies detachably secured in said track and means to detachably position and secure said slider assemblies at any desired location along the length of said track.
  • a toe stop assembly may be detachably secured to the front end of the track so that it can readily be replaced if necessary.
  • truck or slider assemblies which includes a mounting block for the truck or slider assembly thus giving the desired side to side flexibility for the roller skate wheels, said block being slidable within the track on the underside of the side plate and easily clamped in position where desired.
  • truck or slider assemblies are easily removed and replaced with somewhat similar assemblies which can carry an ice skate blade, if desired.
  • reference character 10 illustrates a sole plate preferably made of aluminum and having a heel portion 11, a shank portion 12 and a sole portion 13.
  • a track collectively designated 14 is formed integrally upon the underside of the sole plate and substantially along the longitudinal axis thereof, said track defining a substantially T-shaped recess 15 when viewed in end elevation formed by a pair of spaced and parallel side members or walls 16, having inturned lower edges or flanges 17 terminating in spaced apart relationship to define an entry slot 18 therebetween.
  • a plurality of drillings or apertures 19 are formed through the sole plate thus enabling same to be attached as by screws or the like, to the underside of the sole of a boot or shoe (not illustrated).
  • this sole plate may be embedded or encapsulated within a poured plastic sole 20 between the upper and lower surface thereof, made of nylon or some similar or equivalent synthetic plastic upon which the shoe or boot top portion (not illustrated) may be secured in a conventional manner well known to those skilled in the art of boot and shoe manufacturing.
  • Truck or slider assemblies collectively designated 21 are provided, there being a front truck or slider assembly specifically designated 22 and a rear truck or slider assembly specifically designated 23.
  • the truck assemblies are substantially identical in construction and differ only in the fact that they are reversed with reference to one another, when a pair of such truck assemblies is engaged within the track 14 as will hereinafter be described. Also, in the preferred embodiment, the new truck assembly is provided with stop means as will hereinafter be described.
  • Wings 10A are preferably formed on the sides of the heel portion 11 extending upwardly and slightly outwardly to facilitate retention and anchoring of the sole plate within the plastic sole 20.
  • truck or slider assemblies comprise a plastic or metal slider block collectively designated 23 comprising a main longitudinally extending body portion 24 having a pair of longitudinally extending open sided slots 25 formed one upon each side thereof thereby defining off standing wings 26 on the upper portion which slidably engage within the recess 15 from one end thereof and are retained in selective sliding relationship within the track 14, the inturned edges 17 of the track sides 16, slidably engaging the longitudinally extending grooves or recesses 25.
  • An enlarged portion 27 is formed at one end of the block 23 and a blind aperture 28 is formed in this enlarged portion situated at an angle with respect to the longitudinal axis of the block.
  • a further aperture 29 extends through the block adjacent the opposite end 30 thereof and this aperture is large enough to receive shank portion 31 of a bolt 32 situated at an angle from the vertical axis of the block as clearly illustrated in Figure 4.
  • the head 33 of the bolt is at the lower side of the truck assembly 21 and a washer 34 is provided (and may be integrally formed) upon the inner side of the head and extends circumferencially around the bolt shank 31.
  • a resilient rubber bushing 35 slidably engages the shank followed by a truck component 36, a further resilient bushing 35A, a cup or similar washer 36 receiving the underside of the bushing and a jamb nut or lock nut 37 followed by a positioning washer 38 having lipped portions 39 upon opposite sides thereof which engage around the sides of the block 23.
  • the shank then passes through the aperture 29 in the block and the entire assembly is secured by means of a special nut collectively designated 40.
  • This nut is provided with a sloping undersurface 41 and a shouldered portion 42 which slidably engages the opposite walls 43 of the space or opening 18 between the opposite inturned edges 17 of the walls 16 of the track.
  • Support surface engaging means such as a truck 36, consists of a transversely extending axle support portion 46 through which an axle 47 is fixedly secured with conventional skate wheels 48 being journalled for rotation one upon each end of the axle 47.
  • a bolt shank engaging portion 49 extends from one side of the portion 46 and is recessed on the upper and lower surfaces to receive in nesting relationship, the resilient blocks 35 and 35A.
  • a portion 50 extends upwardly and away from the portion 46 and terminates in a relatively short stub shaft portion 51 which, when the truck is assembled by tightening the bolt 32 relative to the nut 40, engages within the angulated drilling or recess 28 in the end of the block 23.
  • This permits controlled sideways movement of the axle and wheels in the direction of the double headed arrows 52 shown in Figure 3 and is a desirable feature.
  • the block 23 is slidably engaged within the track 14 with the bolt 32 slack relative to the nut 40.
  • the bolt 32 is tightened relative to the nut 40 which clamps the nut and truck assembly in the track, further tightening stiffening the resiliency of the transverse movement of the axle 47.
  • the other truck is then reversed with reference to the first truck assembly, inserted in the track, positioned as desired, and then tightened also.
  • the bolt 32 is merely loosened sufficiently to enable the truck assembly to be moved along the track whereupon the bolt is re-tightened.
  • a toe stopper assembly collectively designated 53 is provided and comprises a resilient block 54 having a recessed aperture 55 formed axially therein and a bolt aperture 56 extending from the center of the recessed aperture 55 all of which is clearly shown in Figure 7.
  • a bolt 57 having a socket-type bolt head 58 passes first through a washer 59 in the recess 55 and then through the bolt aperture 56.
  • a toe stopper block 60 is formed from metal or plastic with a track recess engaging upper plate 61 and a base portion 62 so that it slidably engages the track in a manner similar to block 23.
  • a screw threaded aperture or drilling 63 extends diagonally through the block and receives the bolt 57.
  • the block is positioned in the front end of the sole plate track whereupon bolt 57 is tightened into the screw threaded aperture 63 thus extending clear through the drilling 63 until the distal end of the bolt 57 engages within an inclined aperture or drilling 64 (see Figure 2) formed adjacent the front end of the sole portion 13 of the sole plate 10. This effectively clamps the toe stopper in the desired position yet enables same to be removed readily and easily for replacement purposes, when desired.
  • modified truck assemblies may be secured within the track in a similar manner with a skate blade welded or otherwise secured between the truck assemblies and along the longitudinal axis of the sole plate.
  • Figures 1 to 9 show the holding bolt 32 with the bolt head 33 at the lower end of the spirally shaped nut 40 at the upper end.
  • this bolt and nut may be reversed as shown in Figure 10.
  • the bolt head 33A is shaped in a manner similar to nut 40 with a sloping under surface 41A and a shouldered portion 42A which slidably engages the opposite walls 43 of the slot or opening 18 defined by the opposed inturned edges 17 of the walls 16 of the truck.
  • the nut 40A is preferably an elastic stop nut and is screw threadably secured to the lower end of the bolt as shown.
  • FIG. 1 shows a turnbuckle assembly 65 extending between the bolts 31 adjacent the nuts 37.
  • the eyes 66 on each end engage around the bolt 31 and the barrel 67 can be rotated to adjust the distance between the track assembly 21 and also act as a retainer to prevent inadvertent disengagement of the track assemblies from the track.
  • FIGs 11 and 12 show the preferred embodiment of the bolt collectively designated 68 which is designed to be used in a manner similar to that illustrated in Figure 10 in which the bolt head assembly collectively designated 69 engages the track 14.
  • the bolt includes the screw threaded stem 70 with the head assembly 69 on one end thereof, said head assembly including a cap portion 71 with a shouldered portion 72 formed intermediate the cap 71 and the upper end 73 of the stem 70.
  • the under surface 74 of the cap extends outwardly upon each side of spaced and parallel sides 75 of the shouldered portion 72 and the under surfaces 74 of the extending portions of the cap 71 are serrated as illustrated by reference character 76.
  • These extending sides or surfaces 76 engage upon the upper horizontal surfaces 77 (see Figure 3) of the inturned flanges 17 of the track and when clamped into position by the associated stop nut (not illustrated) assist in preventing untoward sliding movement from occurring between the truck or slider assembly and the track.
  • the truck assembly is referred to as a slider assembly regardless of whether wheels or skate blades are mounted thereon, the term slider assembly referring to the adjustability of the assembly anywhere along the length of the track 14.
