Description

    CROSS-REFERENCE TO RELATED APPLICATION
  • This application claims the benefit of U.S. Provisional Application Ser. No. 60/921,048, filed on Mar. 30, 2007, entitled Spokeless Wheel Inline Skate; the prior application is herewith incorporated by reference in its entirety.
  • BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention pertains to a spokeless or hollow wheel inline skate. Inline skates are used for fitness, fun, and transportation.
  • 2. Description of the Related Art
  • An inline skate typically has includes a set of at least four wheels. The each wheel is provided with bearings. The outer race of the bearing is pressed into a plastic or metal rim of the wheel. A removable axle is inserted through the bearing, at the center axis of the wheel, and into a frame provided for mounting the wheels of the skate in a line.
  • The axles are hollow and have a thread for receiving a screw, which secures the axle and thus the wheel to the frame.
  • The support for the lower leg and ankle in the front to back direction is typically provided by increased stiffness of the back of the skate boot. The increased stiffness of the back of the boot provides stability for the user of the inline skate.
  • The disadvantages of prior wheel configurations are that the axle of the wheel is low to the ground. Therefore, when an object such as a rock, stick, or other debris is struck by the wheels, the wheels are impeded causing the skater to stumble and possibly fall. Furthermore, because the wheels disposed in a fixed relationship to the boot, the wheels cannot deflect to absorb shock when the wheels strike debris. The disadvantages of the support for the lower leg being in the back of the boot is that more support is required on the front side of the leg or shin and increased rigidity in the rear of the boot does provide the best support the front of the leg. The replacement and maintenance of the wheel is time consuming because each wheel must be individually disassembled and rotated or replaced.
  • BRIEF SUMMARY OF THE INVENTION
  • It is accordingly an object of the invention to provide a spokeless wheel inline skate, which overcomes the above-mentioned disadvantages of the heretofore-known devices and methods of this general type and which is more versatile and easier to use and overcomes the disadvantages disclosed above.

  • DETAILED DESCRIPTION OF THE INVENTION
  • In the following description, numerous specific details are set forth. However, it is understood that embodiments of the invention may be practiced without these specific details. In other instances, well-known structures and techniques have not been shown in detail in order not to obscure the understanding of this description.
  • FIGS. 1, and 2 illustrate an inline skate 1 having a boot 2. The boot has a toe area 23 and a heel area 24. The boot can be secured around a foot/lower leg of a skater with straps having buckles and or laces 3. At a toe section of the boot 2 a rigid tongue 4 is affixed in a hinged manner at a pivot 5 so that the rigid tongue 4 can be pivoted away from the boot 2. The rigid tongue 4 has additional pivot points 6 so that the rigid tongue 4 can easily conform to the foot of the skater. The rigid tongue 4 is provided with a soft backing 7 such as foam, padding, or rubber, which allows the rigid tongue 4 to conform to the skater's foot in a comfortable manner. The rigid tongue 4 may be formed from aluminum or a rigid plastic such as polypropylene, nylon, etc. The rigid tongue 4 can project beyond a top 25 of the boot 2 and be strapped by straps 41 directly to the leg 26 of the skater for additional support. Also, the tongue 4 is curved in the direction transverse to a skater's foot in order to conform to the foot and ankle region.
  • FIGS. 1, 4, 5, and 7 show spokeless or hollow wheels 10 that are rigidly attached to a wheel frame 20 that is mounted on a sole 22 of the boot 2. The wheels have a rubber portion 11, which is provided for rolling on a surface that the skater will skate on. The rubber portion 11 is connected to an outer race 12 of a bearing 13. The connection can be via an intermediate ring 34 or the rubber portion 11 may be mounted directly on the outer race 12. It is possible that the rubber portion 11 be removable from the bearing 13 so that the rubber portion 11 can be replaced after it is worn out. It is also possible in this configuration for the entire wheel frame 20 to be removed from the sole 22 of the boot 2 thereby replacing or rotating all the wheels 10 at once.
  • The bearing 13 has also has an inner race 14. A wheel mount 15 is rigidly fixed to the inner race 14 of the bearing 13. The wheel mount 15 is also rigidly attached to the wheel frame 20 thereby affixing the wheel 10 to the skate 1 in a rotational manner. The mounting of the inner race 14 by the wheel mount 15 secures the inner race 14 in a rotationally fixed manner and permits the outer race 12 to rotate thereby allowing rotation of the wheels 10. The wheel mount 15 may be permanently molded to the wheel frame 20 or it can be removeably mounted by fasteners, such as screws. The wheel mount 15 can be a u-shape on both sides of the wheel 10. It is also possible for the wheel mount 15 to be affixed to the inner race 14 on only one side of the wheel 10.
  • FIGS. 2 and 3 show wheels 10 that are mounted in a hinged manner to the wheel frame 20. The wheel mount 15 is affixed to the wheel frame 20 by a hinge or pin 16 on a side of the wheel mount 15 that is towards the front of the skate 1. an elastic member 17 with a fastener 18 affixes the opposite side of the wheel mount 15 (side that is toward the rear of the skate) to the wheel frame 20. The compression of the elastic member 17 allows the wheel to pivot upward around the hinge 16 towards the wheel frame 20 when the wheels 10 strike debris. The elastic member 17 can be provided as a compression spring, TPE element, or rubber element.
  • FIG. 7 shows an enlarged view of the wheel frame 20, wheel 10, and the bearing 13. The bearing 13 is shown as a dual ball bearing, however, it is possible that single roller bearings be used as well. The outer race(s) 12 are rigidly attached to the rubber portion 11 by a t-shaped projection 19 on the intermediate ring 34, which holds the dual ball bearings. While the projection 19 is shown as T-shaped, it is possible for the projection to have any other shape which will hold the wheel to the bearing 13. It is also possible for the outer race(s) 12 to be directly attached to the projection 19. It is also possible for the rubber portion 11 to be molded to the outer race 12, where the outer race 12 is provided with features that will secure or lock the rubber portion 11 thereto. FIG. 7 also serves to illustrate the connection of the wheel mount 15 to the inner race(s) 14 of the bearing 13 and of the wheel mount 15 to the wheel frame 20. FIG. 7 also shows a joint seal 21 between two bearing channels 32 of the dual bearing 13.
