Description

ROCK AND ASSOCIATED WEAR EQUIPMENT DESCRIPTION Background and field of the invention The present invention relates to a rubbing apparatus for joining wear, and the wear associated therewith. More particularly, the present invention relates to a rubbing or sliding plate with friction (grinding) and the wear to which the rubbing plate can be attached. Rubbing is an activity normally associated with inline skates or inline skates, and involves sliding the underside of the skateboard or inline skate along a hard surface such as concrete or metal in such a way that the wheels do not enter. in contact with the hard surface. Slipping or scraping is referred to as rubbing or sliding with friction. Normally the longitudinal axis of the skate or skateboard is transverse to the direction of movement of the skater. Rubbing has its origins in skateboard practice where the skateboards move from one side to another in a half cylinder of concrete. At the edge of the cylinder the skateboarders begin to slide the lower parts of the skateboards along the edge before rolling down the half cylinder or tube. In these maneuvers the wheels of the skate or skateboard are transverse to the direction of movement of the skate or the skateboard. As a result the lower part of the skate or skateboard is scraped or rubbed against the surface being mounted or running, and hence the term friction rubbing or sliding. While skateboarders are familiar with rubbing, with the advent and increased appearance of in-line roller skates and the corresponding intricate movements, rubbing has become an even more popular activity. The inventor of the present invention has developed a shoe and a rubbing plate that allows people to experience and enjoy the rubbing activity without wheels or wheeled vehicles. It is intended that the wiping plate of the present invention be attached to the side or side of the shoe of the present invention. The wiping plate of the present invention can be attached to either the middle side or the side side of the shoe, or both lateral and middle sides. The rubbing plate can be bent to have a substantially U-shape and run through the bottom of the shoe from the middle side to the side of the shoe.

Detailed description of the invention With reference to figures 1 and 2, a first embodiment of the present invention is illustrated. Figure 1 shows one of a pair of shoes, for rubbing in accordance with the present invention. The shoe or shoe 20 is designed so that a user can walk with it in a normal manner in addition to using it to perform rubbing maneuvers. The shoe, although it also has elements found in ordinary shoes, includes a rub plate 25. In the embodiment shown in FIGS. 1 and 2, the rub plate 25 is formed into a U and runs widthwise through the bottom part. of the shoe 20 from the middle side to the side of the shoe 20. The rubbing plate 25 is made either of metal, or of plastic, such as high density polyethylene nylon or Ptex ™, or nylon. The shoe 20 may also have additional protection such as toe rubbing protector 30 and heel rubbing protector 35. The toe rubbing protector 30 and the heel rubbing protector 35 are made of material sufficiently hard to resist a repetitive scrape against metal, concrete, and other similar hard substances. The arc of the U-shaped rub plate 25 can vary through the arch of the shoe 20. While the rub plate 25 of FIGS. 1 and 2 runs in a straight line through the width of the shoe 20, the rub plate 25 can have many different forms. For example, Figure 13 shows another embodiment in which the rubbing plate 25 runs from the toe to the heel of the shoe 20. Similarly, Figures 14a and 14b show embodiments wherein the rubbing plate 25 is formed in a U shape. and extends across the width of the shoe 20. However, unlike the embodiment shown in Figures 1 and 2, the rub plate 25 does not run directly across the width of the shoe but has an angle so that the Rubbing plate is further forward on the side or middle side of the shoe 20 than on the middle side or opposite side side. The rubbing plate 25 does not have to be configured in a U-shape, as shown in the embodiment of the figures 1 and 2. Figure 3 shows a molded insert unit 40, and is designed to fit in the middle part of the sole and / or on the outside of the sole of a shoe. The molded insert unit 40 has a slotted channel 42, similar to the U-shaped configuration of the rubbing plate 25 of the first embodiment. The edge 44 of the molded insert unit 40 has threaded holes 46. The edge 44 shown in Figure 3 is the middle side edge of the shoe, but this may be the side side edge or both the lateral or middle side edges. The molded insert unit 40, in addition to providing attachment for a rubbing plate (not shown), adds strength to the complete sole. The molded insert unit 40 of Figure 3 is intended to be used with the rub plate 25 'and 25"as shown in Figures 6a and 6b, unlike the U-shaped rub plate 25 shown in the figures. 1 and 2 the rubbing plates 25 'and 25"do not run along the bottom of the shoe 20, but are intended to run along the side of the shoe 20. The rubbing plate 25' shown in Figure 6a is shown in FIG. pre-shaped or configured to have a U-shaped slot 48 along its lower edge 48. The rub plate 25", shown in Figure 6b, is not pre-molded or configured and therefore its lower edge 48 is flat. The two rubbing plates 25 'and 25"have a pair of holes 49 therein and correspond to the holes 46 in the molded insert unit 40. The rubbing plates 25' or 25" are attached to the molded insert unit 40. by means of threaded screws (not shown). The 25"and 25" rubbing plates can be made of metal or a plastic such as nylon. The molded insert unit 40 is incorporated in the shoe 20 in FIG. 4. The mid sole / outsole 27 of the shoe 20 is cut to allow clearance for the rub plate 25 'such that the rub plate 25' does not enter. in contact with the ground during normal walking. The rubbing plate 25"can also be used in place of the rubbing plate 25 'A strong belt 50 is shown in Figure 5 which extends around the heel 21, on top of the tongue 22 and under the heel 23 of the shoe 20. The strong belt is provided to strengthen the middle part of the foot 24 of the shoe 20 which allows the user to perform more aggressive street maneuvers, such as rubbing, slipping, jumping, and combinations thereof. on the inner part of the shoe 20, and can be removable.A strong strong belt of nylon 50 can be made of thick nylon and have hook and eye fasteners.The strong belt 50 can be made as an integral part of the shoe 20, installed during production by either sewing on the inside or outside of the shoe 20. Figures 15a-15f show alternative configurations of the rub plate 25 to those shown in Figures 6a and 6b. iar of the front, middle and rear part of the lower edge 49 of the rubbing plate 25 as shown in Figures 15a-15c. Similarly, the depth of the slot 49 can be considerably smaller and at the same time it can be placed in different parts of the rear part to the middle or front of the lower edge 49, as shown in Figures 15d-15f. The shoe 20 is shown in figures 7a and 7b without rubbing plate 25. The sole 31 of the shoe 20 has two front sole portions 32 and rear sole 33. Figure 7a shows the front sole 32 and the rear sole 33 attached to the shoe 20, while figure 7b shows the front sole 32 and the rear sole 33 separated from the shoe 20. By making the sole 31 of separate parts 32 and 33 a vacuum is created in the midsole to accommodate the molded insert unit 40. front sole 32 and rear sole 33 provide rubbing protection to shoe 20 so that this shoe will not wear out in these areas due to rubbing. The front sole 32 and the rear sole 33 may be laminated pieces that are attached to the shoe 20 and eliminate the need for a separate rub plate. The front sole 32 and the rear sole 33 could be joined between the upper part and the lower part of the shoe 20 thereby offering a simplified version of rubbing. A more detailed side view of the rubbing plate 25 'is shown in FIG. 8 attached to an outer sole 31 of the shoe 20. The pair of holes 49 in the rubbing plate 25' are oval here to allow adjustment of the position. of the rubbing plate along the length of the shoe 20. The lower part of the outer sole 31 has a slot similar to the slot 48 at the edge of the bottom of the rubbing plate 25 '. With reference to Figure 9 the threaded holes 48 in the sole 31 can extend fully through the sole 31 from the middle side to the side side. In such a configuration, the wiping plate 25 can be attached to the middle side, the side side, or both the middle side and the side side of the shoe 20. The screw holes are integrally formed with the sole 31 during the manufacturing process.

Figure 10 shows a lower sectional view of another preferred method for attaching the rub plate 25. Instead of having the holes 48 running through the sole 31, separate T-shaped inserts 60 are formed in the sole 31. Each T-shaped insert 60 has a hollow and threaded base portion 61, for attaching screws attaching the rubbing plate 25, and a flange 62 for anchoring the insert 60 in the sole 31. The rubbing plate 25 is attached by means of two screws 70 which are screwed into the holes 48 in the T-shaped inserts 60. Unlike the embodiment shown in Figure 9, the holes 48 on opposite sides of the sole 31 do not have to be in the same. flat. As a result, the rub plate can be attached so that it better follows the contour of the sole side 31. The sole 31, shown in FIGS. 9 and 10, also has shock absorbing or shock absorbing material 80 provided therein. The shock absorbing or shock absorbing material 80 is preferably made of elastomeric polymer material to cushion the impact on the toe or heel. Shock absorbing or shock absorbing material 80 could run through the entire foot in the midsole or outsole. The placement of shock absorbing or shock absorbing material 80 can be clearly seen in Figure 11, between the midsole and the outsole.

With reference to Figure 18, the impact absorbing material 80 can run to the full length of the shoe 20 and be placed below the shoe insole 20. Additional impact absorbing pads 91 and 92 can be placed under the heel and the shoe. toe of the shoe, respectively. The rub plate 25 does not need to be a single plate that is flat on both sides. As shown in Figure 12, the wiping plate 25 may have a flat outer surface 85 and a shroud 86 projecting transversely from the flat outer surface 85 under the sole 31. The shroud 86 may be bent so as to conform to the side of the shoe 20. Such a rounded conformation of the shoulder 86 reduces the pressure of the shoulder edge on the flat surface of the foot and provides a smooth transition from the support areas to the unsupported areas. The shroud 86 can be inserted between the midsole and the outsole and acts to strengthen the lateral stiffness of the shoe 20 to aid in the operation of aggressive maneuvers. Heel hardeners may be inserted in the heel counter of the shoe 20 to strengthen the shoe 20 for normal walking. In addition, a semi-rigid or upright footrest 100 could be included as shown in Figure 20 in the shoe to help prevent the shoe 20 from being contracted during rubbing. In the embodiment illustrated in FIG. 20, the flap 100 is placed in the middle of the sole of the shoe in the middle part of the foot. The enfranque 100 can be made of graphite or metal. The shoe 20 of figure 20 has two rubbing plates 25, one in each on the lateral and middle sides of the shoe 20. The enfranque 100 in the mid sole strengthens the half of the shoe 20 and eliminates bending over the (s) rubbed surface (s). The standing semi-rigid support can be in conjunction with the enfranque 86 and can be placed across the middle part of the foot to strengthen the middle section of the shoe where most of the pressure is applied. Alternatively, a medium and lateral reinforcement system could be employed to prevent the shoe 20 from being contracted during rubbing. The plate of the U-shaped type shown in figures 1 and 2 can be joined in the same manner as the side-mounted rub plate 25 in Figure 8, using T-shaped inserts in the midsole / outsole and screws 70. A rubbing plate 25 may be attached in the lateral orientation of the heel of the shoe 20 as shown in Figs. 19a and 19b where a side flange 25"'' projects from the side of the shoe 20 to" secure. " Such a protrusion could be a molded insert or could be an integral part of the midsole / outsole combination. Instead of screws 70 the wiping plate 25 can be detachably attached by means of a quick-release type system so that the wiping plate can be changed quickly without requiring tools, for example when the shoes will simply be used for walking. Finally, a heel rubbing plate 110 can be provided as shown in Figures 16 and 17, where a portion of the sole 31 is cut to accommodate a rubbing plate on the heel of the shoe 20. Such a rubbing plate can be attached to inserts in the shape of T 60 and screws 70 as previously discussed. Having described various embodiments of the rubbing plate and shoe in accordance with the present invention, it is believed that other modifications, variations and changes will be suggested for people with average knowledge in the matter considering the description given above. It should be understood, therefore, that such variations, modifications and changes fall within the scope of the present invention as defined in the appended claims.
