Spark Creating Recreation or Sports Device

Technical Field

This invention relates to wheeled devices used for recreation and sports such as skateboards, roller blades, roller skates, etc. The new device includes a simple means to create sparks when the device is scraped against an environmental surface such as a street, sidewalk, railing or other similar friction surface.

Background Art

There are currently in use devices for attachment to wheeled sports and recreational products which create sparks when the wheels turn during use of the product. Examples include the attachment of a flint adjacent to a rotating element of the wheel or axle of a wheeled device such as a roller skate. When the roller skate is used by a person causing the wheels to rotate, the flint is struck to cause sparks to be emitted. This application is similar to the use of a rotating wheel in a lighter to rub against a flint to create a spark to light the lighter.

In addition there are complicated mechanisms for holding pyrotechnic materials which may be mounted under skateboards. An example of such a structural device is represented in U.S. Patent No. 4,834,407. In this case part of the housing, i.e., the fins, is consumed in operating the device. Such devices are complicated to manufacture and use in the simple skateboard application.

The present invention provides a recreation or sports device which creates sparks when various surfaces of the device are rubbed against an environmental surface such as a sidewalk. A flint pad is attached to the device surface which is intended to be used to create sparks. When the recreation device is used such that it is in motion the proper device surface with flint pad is caused to rub against an environmental surface causing friction which

creates the spark.

Disclosure of Invention

A primary objective of the present invention is to provide a recreation or sports device which creates sparks when a device surface is rubbed against an environmental surface.

In accordance with the description presented herein, other objectives of this invention will become apparent when the description and drawings are reviewed.

Best Mode for Carrying Out the Invention

The spark creating recreation/sport device consist of flint pads attached to device surfaces which are intended to be brought into contact with environmental surfaces when the device is in use. If a skateboard has flint pads attached to the front and rear bottom surface, when the board is tilted on the front or rear wheels the flint pad may be brought in contact with the ground thus creating sparks. When flint is referred to herein the meaning is for any material used for producing sparks such as alloys of various commonly known elements and metals with such properties.

Referring to Figures 1 through 5, a skateboard (1) has flint pads (2) attached to an environmental contact surface (13) such as the front edge (3), rear edge (4) and sides (5) . The flint pad (2) may be a simple rectangular shape or may be formed in a strip which may be molded around the curvature of an edge such as the front edge (3) . As illustrated in Figures 2, 3 and 5 when the flint pad (2) is rubbed against an environmental surface (6) such as a sidewalk or railing, the friction causes sparks to be

emitted. In Figure 5 the flint pad (2) is attached to the bottom center (14) .

Referring to Figure 6, a roller blade (7) has a flint pad (2) attached to the brake pad (8) .

Referring to Figures 7 through 10, a flint pad (2) is attached to various protective devices used with recreational wheeled devices. An arm protector pad (9) , knee protector pad (10) and hand protector pad (11) are illustrated. In addition a helmet (12) may be fitted with a flint pad (2) .

Referring to Figures 11 through 15, a pad mount (15,17) may be used to attach to the skateboard (1) . In this embodiment the flint pad (2) is attached to the pad mount (15,17) which has an adhesive surface (16) or fastener aperture (18) for attachment to the skateboard (1) . The pad mount (15,17) may serve as a heat shield to protect the skateboard (1) surface from heat damage.

Referring to Figures 16 and 17, a pad mount (19) has wheel mount apertures (22) corresponding to a particular skateboard (1) wheel mount (23) . This allows the pad mount

(19) to be attached without drilling additional holes in the skateboard (1) . The pad mount (19) has folded edges (21) on three sides to allow insertion and removal of slide mount

(20) which has the flint pad (2) attached. This provides a simple means to replace used flint pads (2) .

Referring to Figures 18 through 20, means to mount flint pads (2) directly to the skateboard (29) include using a fastener (24) such as a screw, bolt and the like. In such an attachment, a heat shield (30) to protect the skateboard (29) may be inserted between the skateboard (29) and the flint pad (2) . In Figures 18 and 19 the fastener (24) is molded into the flint pad (2) . The skateboard (29) has either a threaded insert (25) or a through board insert (26) to receive the fastener (24) . Figure 20 illustrates a flint pad (2) which has a fastener aperture (28) through which a fastener (27) may slide to engage threaded insert (25) .
