Definitions

  • the present invention is directed to systems for powering and maneuvering a roller-skate in line skate and the like.
  • the present invention is specifically directed to devices for mechanically driving roller skates, in line skate, skateboards, and the like, in an easy and safe fashion and one which provides minimal interference to the enjoyment of the user.
  • U.S. Patent No. 4,508,187 discloses a power attachment which is affixed to the front wheel of a roller skate and which drives the wheel forward. While such systems provide power, such direct drive systems provide a highly unnatural feel to the operation of the skate or skateboard. Such systems are difficult to control and stop, and may also lead to frequent accidents and injuries. A further problem associated with these systems, is the requirement for a cumbersome back-pack type frame. These products also typically include a pair of handle bars which extend forward of the user. Such systems are uncomfortable and confine the operation of the user, and also do not provide the feel of a regular skate, roller blade or skateboard.
  • 3,876,032 for example discloses a belt drive which incorporates an electric motor mounted on a platform which is powered by a battery worn by the operator (See Figure 3) .
  • the battery, mounted on a belt preferably includes a control panel which switches the system on and off and controls the speed of the device.
  • U.S. Patent No. 5,433,284 and 5,368,122 discloses a bicycle power pack comprising a frame which mounts a motor and a transmission mechanism which is hitched to the rear of bicycle frame.
  • U.S. Patent No. 5,368,122 discloses an electrical bicycle drive mechanism. None of these devices suggest application to a roller blade, roller skate, ice skate or ski.
  • U.S. Patent No. 3,797,446 discloses a rear powered mobile power unit.
  • U.S. Patent No. 4,456,089 discloses a motorized device for pushing or pulling a skate. This device when used for rear propulsion, drives the user through his legs and is therefore difficult to use.
  • U.S. Patent No. 5,127,488 discloses a motor driven skateboard which is sold as the Power Board by'TSI of San Luis Obispo, California. Muttermutt, Inc. of Fort Lauderdale, Florida has provided a propulsion system for skateboards, roller blades and the like.
  • the Muttermutt device is driven from the front and thus pulls the skater along much like a motorcycle.
  • the Muttermutt device therefore does not simulate the feel of a roller blade and the user does not use his skates or the board for steering and control.
  • the Muttermutt systems pulls the user.
  • the user of the system is also subjected to a large quantity of exhaust from the engine and vibration. Accordingly, the use of the roller blade or skate is unnatural and uncomfortable. More importantly, because the device brakes from the front, the user can easily be thrown over the handle bars if the device stops suddenly.
  • the device incorporates a safety kill switch which disconnect the motor when the rider falls or loses control of the device.
  • the drive mechanism includes a gear box mechanism.
  • a device for propelling a skater or operator from the rear comprises a frame to be held by the user which supports a drive wheel; means affixed to the frame for propelling the wheel and driving the user forward; and braking means for stopping the device.
  • the present invention is directed to a motorized system for propelling a roller blader from the rear comprising: a longitudinally extending frame supporting a drive wheel for driving a roller blader from the rear; an engine affixed to the frame for propelling the wheel and roller blader forward; handle means affixed to said frame for allowing the user to support the frame and propel himself forward; throttle means affixed to said handle for controlling the speed of said engine; and braking means affixed to said handle for braking said device.
  • the present invention is directed to a motorized system for propelling an operator from the rear comprising: a longitudinal frame supporting a drive wheel at a first end of said frame for driving a roller blader from the rear; a gasoline powered engine affixed to the frame for propelling the wheel and roller blader forward; handle means affixed to a second end of said longitudinal frame for allowing the user to support the frame and propel himself forward; throttle means affixed to said handle for controlling the speed of said engine; and braking means affixed to said handle for braking said device.
  • the system of the present invention may include a retractable tow line.
  • Figure 1 is an elevational view of the preferred roller blade propelling system of the present invention.
  • Figure 2 is an isolated view of power drive mechanism of the roller blade propulsion system of the present invention.
  • Figure 3 illustrates the present invention in operatio .
  • Figure 4 is a side view of an alternative drive mechanism of the present invention.
  • Figures 5A and 5B are respective side and overhead views of a gear box for use in the present invention.
  • Figure 6 is a perspective view of an alternative gear box drive mechanism for the present invention.
  • Figure 7 is is a side perspective view of a belt based control mechanism.
  • FIG 8 is a plan view of an alternative frame mechanism is accordance with the present invention.
  • the present invention is now described with reference to the enclosed Figures wherein the same numerals are utilized where applicable.
  • the invention in a most preferred embodiment comprises a frame 12 affixed to a drive wheel member 14 which is held behind the user and which propels him forward.
  • the frame 12 extends longitudinally and is between 3.5 and 4 feet in length.
  • frame 12 comprises a plurality of metallic tubing and may include, cross members 12a which, as will be discussed below, support an engine or other propulsion means 20.
  • the drive wheel member 14 comprises tire 16 with a spoke or aluminum wheel 18.
  • the invention incorporates a power drive mechanism 20 attached to the frame 12.
  • the power drive mechanism 20 comprises a gasoline engine, for example, a 33 to 40 cubic centimeter single cylinder engine such as the MX-5 Superbike Engine. Such engines obtain up to one hundred and fifty miles per gallon of fuel.
  • the engine 20 attaches to the frame 12 and powers the wheel 18 and tire 16 by means of a friction clutch (not shown) .
  • Wheel 18 and tire 16 are shown for illustrative purposes and may be provided in many different sizes and radii. Alternatively, it is to be appreciated that other drive mechanisms such as drive chains and the like could be substituted for the friction clutch.
  • the engine 20 should preferably output approximately 1.0 to 2.0 horse power. Engines such as the MX-5 Superbike can achieve speeds of up to thirty miles per hour.
  • the system further includes a fuel supply 23 which is attached to the frame 12.
  • the present invention is being described with reference to a gasoline engine, that other power sources such as electric or jet power can be applicable to the present invention.
