     DETAILED DESCRIPTION 
     There are many items on the market to aid people while getting up on water skis; however, to our knowledge we have found nothing on the market for kneeboards. 
     A kneeboard is a planing device which is towed behind a moving boat. 
     The kneeboard is the only floatation device designed to ride in a kneeling position. All other devices are designed to be ridden in a standing position. Kneeboards allow one to perform maneuvers different from other floatation devices. On the kneeboard it is important to strap oneself in after the board is planing above the water. However, one cannot be in this position when starting out. 
     A kneeboard was initially considered as an alternative to water skis which could be enjoyed without significant training or experience. Although it may seem easy to hold a tow rope handle and pull oneself up on a kneeboard to be pulled across the water, in many instances it is difficult for a rider to get from a lying position in the water to the kneeling position while the kneeboard is being pulled. Therefore, many kneeboard users have difficulty in performing the maneuvers which are necessary in order to attain the kneeling position as the kneeboard is towed. The tow rope holder of the present invention makes it easier to attain this position. 
     As previously mentioned, a problem or drawback of a kneeboard is getting up from a lying position to a kneeling position while being pulled through the water. The tow rope holder of the present invention solves this problem by cradling the towing rope handle thereby freeing the hands of the rider to balance the kneeboard and pull the body of the rider up to a kneeling position. 
     The tow rope holder of the present invention is also advantageous in allowing small children or others who do not have the strength to hold the towing rope and maneuver the kneeboard to get up to a kneeling position for the ride. Thus, the chances of a novice being able to get up on the kneeboard the first time without having any experience or practice are improved. 
     Accordingly, the tow rope holder of the present invention is particularly suitable for use on kneeboards operated, for example, by resorts and kneeboard rental businesses to help promote the rentals of kneeboards because many people who rent kneeboards are beginners or novices to the sport. 
     The tow rope holder of the present invention is also particularly suitable for use by water sport schools to assist beginners to get up on the kneeboard without encountering the previously mentioned difficulties. 
     Thus, the tow rope holder of the present invention complements the kneeboard and would give assurance to sports persons concerned about the difficulty of getting up on the kneeboard. 
     Unlike a ski board on which a rider rides while standing with feet in stirrups, the kneeboard is ridden while the rider kneels on the board. To maintain the rider on board the kneeboard, and to permit the maneuvering of the board without separating the rider from the board, a strap is utilized which passes over the thighs of the rider to aid in preventing his separation from the board. This strap must be positioned and adjusted after the kneeboard has been drawn into motion by movement of the towing boat. To initiate the ride on a kneeboard, the rider holds the handle of the tow rope with one or both hands while lying generally prone on the kneeboard, holding the kneeboard with one or both hands. As the two vehicles begin to move, the rider must maintain hold of both the tow rope handle and the kneeboard. As the kneeboard begins to plane, the rider positions himself on his knees, atop the board and adjusts the strap across his thighs to maintain himself in contact with the board, while holding on to the handle of the tow rope. Eventually, with straps secure, the rider signals the tow vehicle to accelerate. As can be appreciated, the necessity to hold on to the tow rope handle while positioning oneself on the towing device can present a difficult challenge to persons attempting to ride a kneeboard. 
     It is the intent of the present invention to provide improvements in such aquatic recreational devices as to minimize such difficulties and to allow a rider to more readily initiate and complete the previously described maneuvers necessary for riding a kneeboard. 
     The tow rope holder of the present invention is also advantageous in minimizing the stress encountered by a rider attempting to hold a tow rope handle against the force of a moving tow vehicle while maneuvering an aquatic device into position to initiate a ride thereon. This is done by transferring the initial towing forces directly to the towing device thereby eliminating stress induced in the hands and arms of the rider as the ride begins. 
     The tow rope holder of the present invention is also advantageous in allowing a person who experiences fatigue to replace the rope in the tow rope holder of the invention in order to rest a few minutes or, if the rider finds his body is not in a proper position, the rope can be replaced in the tow rope holder of the invention to allow the rider readjust the body. 
     As shown in FIG. 1, the tow rope holder of the present invention, also described herein as a &#34;connector&#34;, is described in more detail hereinbelow. 
     The connector 1 includes a base surface 2 having a front end 3 and a back end 4; an upper surface 5 sloping at one end 6 to connect with the base surface at the front end; and a third surface connected between the back end 4 of base surface 2 and another upper surface 8. 
     The third surface 7 has a lower end 7a which is preferably substantially perpendicular to the back end 4 of the base surface 2, and an upper end 7b joining the other end of the upper surface 8. 
     The third surface includes a curved section 7c between the lower end of the third surface and the upper end of the third surface, in addition to a substantially flat section 7d between the lower end of the third surface and the curved section of the third surface. As shown, the curved section of the third surface is substantially contiguous with the upper end of the third surface. 
     The connector of the present invention, as described above, also has opposite sides 21 connected at a joint 22 between the upper surface and the base surface which includes means for attachment to a support which are preferably in the form of lateral flanges 23 extending outwardly beyond the joint at which each of the opposite sides are connected to the base surface. The lateral flanges 23 preferably are provided with openings 24 for receiving attachment elements, such as screws (not shown), by which the support is attached to the base surface. 
     The tow rope holder is preferably composed of nylon and plastic mixed products. 
     The tow rope holder of the present invention is preferably 3 inches wide, 5 inches long, and a 1/2 inch high at the point sloping up to 1.75 inches to a hook shaped portion. The tow rope holder of the present invention is preferably attached to the kneeboard with 6 screws, 3  screws on each side of the hook. The tow rope holder of the present invention is preferably centered on the kneeboard about 1.5 inches from the point of the kneeboard. Attaching the tow rope holder of the present invention with screws allows for a margin of error and also for the removal of the tow rope holder of the present invention if so desired at a later date. 
     Placement of the tow rope holder of the present invention on the kneeboard from the center point the kneeboard, is preferably about 1.5 inches down from the point, not to exceed 2 inches. Placement is very important to allow the board to plane as soon as possible. Placing the tow rope holder too far back causes the kneeboard to nose dive into the water thus causing the rider to fall off. 
     Referring now to FIG. 2, the connector 1 or tow rope holder of the present invention is shown mounted to a knee board 201 as the support therefor. 
     In FIG. 3, a kneeboard 201 is shown which has been modified with a predetermined number of openings or orifices 324 that may be drilled or otherwise formed directly in the body of the kneeboard for receiving attachment elements, such as screws or other suitable fasteners, for attaching the tow rope holder 1 to the kneeboard 201. The number of openings or orifices 324 should at least equal the number of openings 24 in lateral flange 23 of connector 1. However, a greater number of openings 24 may be provided so as to permit adjustment of the placement of the connector 1 on the kneeboard depending on the size of the user. 
     In FIG. 4, a kneeboard 201 provided with mounting strips or rails 401 is illustrated. In this embodiment, openings or orifices 424 for receiving the attachment elements are provided in the mounting strips rather than directly in the kneeboard. The mounting strips 401 are preferably fixed to the surface of the kneeboard using a suitable means for this purpose, preferably an adhesive that effectively secures the mounting strips to the surface of the kneeboard. The mounting strips secured to the surface of the kneeboard are advantageous in that doing so eliminates drilling holes directly into the kneeboard itself. Accordingly, the mounting strips 401 and the tow rope holder of the present invention may be removed from the kneeboard, and reinstalled on a different kneeboard if so desired without permanent alteration of the structure of the kneeboard. Related to this, the kneeboard to which the tow rope holder of the present invention was initially attached would not be permanently marred by open or filled-in orifices that would otherwise be visible after the removal of the tow rope holder. 
     The design of the tow rope holder of the present invention is advantageous in a number of respects. For example, the rider can use both hands any time to grasp the tow rope. Flush mounting the tow rope holder of the present invention to have a 90° joint between the tow rope holder of the present invention and the kneeboard is important for ease in removing and returning the rope to the tow rope holder of the present invention. The tow rope holder of the present invention does not detract from any use of the kneeboard. The materials used for construction can withstand the affects of UV rays, water (salt &amp; fresh), and abuse. The materials preferred for use in manufacturing the tow rope holder of the present invention is Durethane 30% glass filled nylon available from Miles Manufacturer. The surface area is designed to accommodate existing kneeboards or new kneeboards and to displace pulling stress over total surface of the tow rope holder of the present invention. 
     Although described herein for use with a kneeboard, the tow rope holder of the present invention may be used on any aquatic planing device where the rider stays in a seated or kneeling position on the device.
