SKATE BOARD CONSTRUCTION Filed April 28, 1965 INVENTOR. FEED P. T/ETCvE BY '@/%m United States Patent 3,331,612 SKATE BOARD CONSTRUCTION Fred R. Tietge, 3963 Mount Blackburn, San Diego, Calif. 92111 Filed Apr. 28, 1965, Ser. No. 451,462 1 Claim. (Cl. 280-1128) This invention relates to a skate board construction and more particularly to a skate board construction wherein the supporting axle for the skate boards wheels is suspended in a block of resilient material that provides an improved, controlled and shock absorbing pivotal movement.
There are many designs and constructions of wheel supports for roller skates, skate boards and the like. Several of these constructions use resilient or yieldable material to cushion the contact shock of the wheels engaging a supporting surface. However difiiculty has been encountered in attempting to provide a wheel support having a cushioned axle that permits the desired degree of freedom of pivotal movement of the wheel axle while still having the cushioned and vibration and shock absorbing axle suspension. Most prior art cushioned axle constructions are complicated, are expensive to make, do not allow the desired degree of resilient support, and are not guided sufliciently, Those that satisfy some of the prior disadvantages, limit the turning and twisting motion of the Wheel axle. Further in many cushioned axle constructions, while the axle to a degree is supported by resilient material, there still is metal to metal contact from wheels to skate board that carries the vibrations and shock of wheel contact through to the skate board, roller skate or the like.
It is therefore anobject of this invention to provide a novel and improved skate board or roller skate consrtuction.
It is another object of this invention to provide a novel and improved wheel axle guiding and cushioning construction.
It is another object of this invention to provide an improved and novel, integral, vibration and shock absorbing axle suspension for the wheels of a skate board, roller skates or the like.
It is another object of this invention to provide an improved and novel skate board structure wherein the axle and wheels turn against a spring action and thrust resisting axle retention. 7
It is another object of this invention to provide an improved and novel, cushioned, vibration and shock absorbing axial suspension that is simple and inexpensive to make and yet that permits a wide degree of guided, pivotal movement.
It is another object of this invention to provide a novel and improved skate board structure wherein the wheel supporting axle pivots around the center of its longitudinal length.
The present invention is directed to the construction of a skate board, roller skate or the like in which the wheel supporting axle is solely suspended in a block of resilient material and guided in pivotal movement, within the allowable yield of the resilient block, by diagonal slots in the supporting bracket. To skillfully use skate boards, it is desirable that the wheel axle have sufficient interstructural flexibility so that it shifts and twists with resiliency and snap return action. This insures the turning of the skate board in the preferred skillful manner by application of an appropriate turning force and a similar return of the wheel axle to the normal or forward position upon removal of the turning force. This maneuver of turning the wheel axle with respect to the skate board frame is accomplished by tilting the frame to one side or the other while retaining the skate wheels 3,331,612 Patented July 18, 1967 firmly upon the supporting surface. The coordination of the user in accomplishing these maneuvers is often determined by the quality, controlled flexibility and uniform responsiveness of the skate boards suspension system. The suspended axles of this invention are imbedded in a resilient material that subjects substantially uniform compression and tension forces on the length of the Wheel axle when pivoted in the manner previously described. The axle is press fit or imbedded in the block of resilient material and because of friction therebetween resists rotation with the wheels. The cushioning resilient block withstands the normal compression forces due to the weight of the skater while providing a high degree of resilience between skate board frame and wheel axle as the wheels contact the supporting surface.
There are other objects, advantages and features of the invention that will become more apparent from the following specification when taken in connection with the accompanying drawings wherein like reference numerals refer to like parts throughout and:
FIGURE 1 is a side view part in section and part broken away of a skate board having the wheel bracket suspension of this invention;
FIGURE 2 is a perspective view of the bracket, resilient block and wheel supporting axle assembly of this invention;
FIGURE 3 is an end view illustrating the turning of the skate board; and
FIGURE 4 is a plan view of the plate.
Referring now to FIGURE 1, a skate board 20 has a board or stage mounted on traction wheels for use in the well known manner. The board 22 may be made of Wood, metal or the like and may have any desired length. The boards function is to support the feet or other portions of the users body. It has a U shaped bracket 24 suspended from the lower surface. The U shaped bracket, that may be constructed from heavy gauge sheet metal or from other suitable materials, has outwardly projecting flanges 26 and 28 that face against the underneath surface of the board 22. Apertures 30 receive screws 32 for securing the bracket 24 to the board 22. Positioned in the bottom of the U shaped portion of the bracket is a block of resilient material 46 that may be made of resilient rubber, suitable resilient plastics, synthetic rubber or the like. The block 46 has a shape as shown in FIG- URE 1 that conforms with the lower portion of the U shaped member 24, A plate 42 having cars 44 rests in appropriate slots 34- at each side and end of the U shaped member 24 and prevents vertical upward movement by the resilient block 46. While the resilient block 46 is held in the bottom of the U shaped member by plate 42, the block 46 is not in a compressed condition.
The U shaped member or bracket 24 has diagonal slots 38 in each side 37 and 39. The bottom corners of the U shaped bracket 24 are concave and receive the bottom of diagonal slots 38. The block of resilient material 46 has a hole 48 bored through its volume which hole is perpendicular to the sides of the block and that is in a plane spaced equidistant from the bottom surface. An axle 50 for carrying the wheels 58 has a diameter considerably larger than the aforesaid hole 48 and is press fitted through the hole to a point that the center 56 of the axle length is at the center point between the sides of block 46 and the U shaped bracket 24. The axle 50 has flared portions at the center 56 for projecting into the resilient material 46 and increasing the already existing friction force between the outer surface of the axle 50 and the inner surface of the hole 48 in the resilient block material. This friction prevents axle 50 from rotating with the wheels around its longitudinal axis within the block of resilient material 46. It should be recognized that axle 50 may be suspended in block 46 by any of several conconstruction,
struction techniques such as by imbedding, molding therein, press fitting, or the like.
Axle 50 in projecting through the resilient block 42 extends through diagonal slots 38 as shown. In the preferred there is a minute spacing between the outer surface of the axle 50 and the inner edge of the diagonal slots 38. This permits relatively free movement of the axle 50 in slot 38. However slot 38 guides the axle in any such movement by contact therebetween. In normal turning of the skate board one end of the axle 50 drops downwardly and the other end of axle 50 rises. This causes axle 50 to be in different positions in each of the respective diagonal slots 38 which induces the pivotal motion to the axle 50 that causes one end of the axle to move forward relative to the other end and to the skate board. The wheels 58 are mounted on axle 50 against ears 54 in the manner shown. The end of the rod 50 is enlarged at 52 for preventing the wheels from moving oif the end of the rod 50. The wheels may be of any type construction and preferably have ball bearings.
In construction the U shaped bracket 24 receives the resilient block 46 which block has the hole 48 out therethrough. Bracket 24 is then bent around block 46 to the assembled condition (see FIGURE 2) with plate 42 inserted in a position shown. Axle 50 is then forced through I hole 48 with the ends of axle 50 projecting out through diagonal slots 38. The bracket 24 is then secured to the underneath surface of the skate board in the manner shown. As is well known skate board or roller skates have two identical bracket and wheel axle combinations spaced along the length of the board.
In operation the board 22 of the skate board 20 is freely rollable on wheels 58. A user or operator places his feet or other parts of his body on the board 20 with the person and board all moving together on the aforesaid wheels. When'it is desired to maneuver the skate board by shifting the users weight toward one or the other edges of the skate board 20, the board is then rotated, as shown in FIGURE 3, relative to axle 50 that is held in a position level with the supporting floor. The tilting board 22 changes the position of axle 50 in diagonal slots 38 thereby causing one wheel to move forward and the other wheel to move rearward. When the operator moves or shifts his weight back to a center'position on the board 22, then the wheels again move to an aligned position in slots 38 and the board moves along a straight line. The board 22 of course may be tilted toward either side as shown in FIGURE 3 with the resultant turning of the wheels to the right or left. It can be seen that the center point of the pivoting by axle 50 is at the center point of the skate board and that each end of axle 50 can move upward or downward in slots 38. This free movement permits a larger amount of guided pivotable movement relative to a given height and witdh of bracket member 24. When axle 50 pivots in the flexible block 46 and the material yields to this movement, the material under that portion of the axle 50 that moved downward is in. com ression and thus exerts an expansive force upwardly. The material above this portion of axle 50 is pulled creating tension forces that exert force on the axle 50 in the same direction as the aforesaid expansive force. The same forces are created in the reverse direction on the other end of the axle 50. These forces are distributed over the length of the axle that is in the block and thus increases the force or snap action that returns the board to upright position. This increases the feel the user has in riding the skate board.
