BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention is directed to entertainment devices and more particularly to a skateboard and specifically to a leash that is to be attachable to the skateboard which the rider can use to hold the rider&#39;s feet against the skateboard while performing aerial maneuvers. 
     2. Description of the Related Art 
     Skateboards have been commonly used for many years by young people. Within recent years, the riding of skateboards has developed into a sport. Frequently, the sport includes a multitude of maneuvers most of which are aerial. When performing of an aerial maneuver, the skateboarder requires that the skateboard be held against the rider&#39;s feet. If the skateboard becomes separated from the rider&#39;s feet, almost invariably the skateboarder will “crash” when landing on the surface after performing of the aerial maneuver. 
     In the past, in order to keep the skateboard against the rider&#39;s feet, it is common for skateboard to manually grasp with one hand the skateboard platform and hold the skateboard platform against the rider&#39;s feet. This procedure of holding the skateboard platform requires that the skateboarder assume a crouching position. If the skateboarder could continue in an upright position, the appearance of the aerial maneuver would be substantially enhanced. Additionally, if the skateboarder can remain in a more upright position, a substantially improvement in the aerial maneuver is invariably obtained. The improvement, generally, is related to the skateboarder rising to a greater altitude in performing of the aerial maneuver. If the skateboarder is performing in a tournament and is being judged as to the quality of the aerial maneuvers, the skateboarder would undoubtedly receive higher marks if the skateboarder is in a more upright position than in a crouched position. 
     Within the prior art, there have been various types of devices used to keep the skateboard platform against the rider&#39;s feet when performing of aerial maneuvers. These prior art devices have frequently resulted in a specific configuration of skateboard and such devices are not capable of being used with a conventional skateboard that is purchased within a store. It would be desirable to design a skateboard leash that permits the rider to hold the board against the feet of the rider during all types of aerial maneuvers and the device is capable of being readily attached and detached from a conventional skateboard. 
     SUMMARY OF THE INVENTION 
     A basic embodiment of this invention relates to a skateboard leash adapted to be attached to a skateboard which utilizes a mounting strap which is to be mounted transversely across the skateboard platform. A swivel joint mechanism is connected to the mounting strap. An elongated strap assembly is connected to the swivel joint with the elongated strap assembly having an outer free end and at the outer free end is mounted a bulbous member. The bulbous member is adapted to be grasped by the rider with a pulling force to be applied to the elongated strap assembly which will hold the skateboard against the rider&#39;s feet when performing aerial maneuvers. 
     A further embodiment of the present invention is directed to modifying of the basic embodiment by removably securing the mounting strap to the skateboard platform. 
     A further embodiment of the present invention is directed to the just previous embodiment by modifying the just previous embodiment by including of a buckle in conjunction with the mounting strap. 
     A further embodiment of the present invention is where the first basic embodiment is modified by the bulbous member mounted at the outer free end being defined as a ball. 
     A further embodiment of the present invention is where there is included a length adjusting strap assembly located between the swivel joint mechanism and the elongated strap assembly. 
     A further embodiment of the present invention is where the first basic embodiment is modified by the elongated strap assembly being defined as a folded over inner elastic tube mounted within a covering tube.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring particularly to the drawings, there is shown in  FIG. 1  a skateboard  10  which is constructed of a platform  12  upon which is mounted on the undersurface a pair of spaced apart roller trucks  14  and  16 . The skateboard leash  18  includes a mounting strap assembly  20  which is composed of a flexible, flat strap  22  which is mounted in conjunction with a buckle assembly (not shown). The mounting strap  22  is to be wrapped transversely around the platform  12  and then by using of the buckle assembly that is tightened securely in position. Typically, mounting strap assembly  20  will be located near the longitudinal center of the platform  12  but may be mounted slightly rearwardly or slightly forwardly according to the individual riders desires. The buckle assembly in conjunction with the mounting strap assembly  20  is deemed to be conventional and forms no specific part of this invention. Actually, any structure would be usable in conjunction with the mounting strap  22  that would snugly tighten the strap assembly  20  onto the skateboard platform  12 . 
     Mounted in conjunction with the mounting strap  22  is a swivel joint assembly  24 . The swivel joint assembly  24  includes a first link  26  and a second link  28 . The links  26  and  28  are mounted together by a pivot pin  30 . The first link  26  is longitudinally held in position between discs  32  and  34  which are mounted on the pivot pin  30 . The second link  28  is longitudinally held in position between discs  34  and  36  with disc  36  also being mounted on the pivot pin  30 . The result is the second link  28  can freely pivot three hundred and sixty degrees relative to the first link  26 . This free pivoting is desirable as during usage of the skateboard leash  18  of this invention the user will frequently twist the leash when making of aerial maneuvers. 
     Mounted in conjunction with the second link  28  is a flexible strap  40  of a length adjusting strap assembly  38 . The strap  40  also connects to a ring  42 . The strap  40  also connects to a buckle frame  44  which includes a pivotable lever  46 . The pivotable lever  46  is spring biased by a coil spring  48  to a binding position which exerts a clamping action against the strap  40  which is slipped around rod  50  of the buckle frame  44 . Manual movement of the pivotable lever  46  away from the clamping position will permit the strap  40  to be moved relative to the buckle frame  44  so that the adjustable strap assembly  38  can be lengthened or shortened according to individual desires. In other words, if a tall rider is using of the skateboard  10  of this invention, then the adjustable strap assembly  38  will be lengthened. If a short rider is using of the skateboard  10 , then the adjustable strap assembly  38  will be shortened. 
     The ring  42  is connected to a folded over section of an elastic tubing  52 . Typical elastic tubing would be tubing that resembles a bicycle inner tube. The free ends of the elastic tubing  52  are conducted through narrow hole  54  formed within a bulbous member, such as a ball  56 , which may be constructed of wood, plastic or other similar type of material. After the elastic tubing  52  is conducted through the narrow hole  54 , it connects with enlarged chamber  58  of the ball  56 . The ends of the elastic tubing  52  are then tied into a knot  60  and then permitted to remain within the enlarged chamber  58 . Because of the knot  60 , the elastic tubing  52  is not capable of withdrawing exteriorly of the narrow hole  54 . The enlarged chamber  58  is then closed by means of a plug  62  so the knot  60  will then be hidden from view. 
     For appearances sake, it is normally desirable to have the elastic tubing  52  to be covered. Therefore, there will be a tube cover  64  located over the elastic tubing  52  and extending between the ball  56  and the ring  42 . 
     The operation of the skateboard leash  18  of this invention is as follows: With the leash  18  mounted to the skateboard platform  12 , as shown in  FIG. 1 , a rider is capable of using a skateboard in a normal manner with the rider&#39;s feet (not shown) resting on the upper, surface  66  of the skateboard platform  12 . When the rider is performing of aerial maneuvers, the rider is to grab onto ball  56  and will exert a manual pulling force that will tend to maintain the upper surface  66  of the platform  12  in contact with the souls of the shoes of the rider. The fact that the elastic tubing  52  is used, if there is a slight release of the pulling force the elastic stretching of the tubing  52  will retract somewhat but will still maintain the upper surface  66  in contact with the soles of the shoes of the rider of the skateboard  10 . 
     Although the elastic tubing  52  has been shown to be preferable, it is considered to be within the scope of this invention that the other elastic materials could be utilized, such as surgical tubing, a bungee cord or other types of elastic tubing. The skateboard leash  18  of this invention can be used as a training tool for beginners giving the rider an element of comfort when performing of aerial maneuvers. Also, for experienced riders, the skateboard leash  18  of this invention permits the experienced riders to achieve higher in altitude aerial maneuvers and also higher in quality aerial maneuvers. The skateboard leash  18  of this invention enhances the overall fun of the sport of skateboarding.
