Abstract:
A device to aid in the demonstration of the tying of knots is described. The device encompasses a tower with a base, a length of rope or twine, and eyelets on the tower to accept the rope. Optional features include a latch at the end of the rope, and a device for storage of the rope.

Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to the field of training devices and more particularly to a training device for the demonstration and learning of the art of tying knots in rope or string. 
       BACKGROUND 
       [0002]    Included in the researched prior art is U.S. Pat. No. 6,412,833 B2. This US patent issued on Jul. 2, 2002, to inventors Lusk and Lusk. The invention described therein is a knot teaching system, and thus is in the same field as the current invention. However, the device is not at all a board, or a tower, but a 3-dimensional fishhook-like device. 
         [0003]    Related art is also presented in U.S. Pat. No. 4,871,200, which issued on Oct. 3, 1999 to inventors Ryder et al. This patent describes a board-mounted device for facilitating the tying of a knot in fishing line. It looks quite a bit different from the current invention, and suffers the drawback of being essentially two-dimensional. 
         [0004]    U.S. Pat. No. 4,764,119, which issued on Aug. 16, 1988 to inventor Miraglia, is also of related interest. The invention therein described is a learning device for teaching young children to tie simple knots. 
         [0005]    Although the above prior art is considered to be relevant to the current invention, no description has been found that anticipates the current invention, nor that renders the current invention obvious. 
       SUMMARY OF THE INVENTION 
       [0006]    The invention herein described and presented is a mechanical device for the assistance of a demonstration of knots, and the tying of knots. The following objects of the invention are presented by means of illustration only, and are in no manner meant to limit the scope of the current invention. 
         [0007]    It is therefore an object of the present invention to provide a non-complex platform to display knots in rope or twine. 
         [0008]    It is further an object of the present invention to provide a means to display various forms of knots. 
         [0009]    It is further an object of the present invention to achieve comfort through ergonomic design of the device. 
         [0010]    It is further an object of the present invention to provide an easily visible display of knots, and of the process of tying a knot. 
         [0011]    It is further an object of the present invention to produce a tasteful and esthetically pleasing article that could be displayed in a home or school. 
         [0012]    Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0024]    Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner. 
         [0025]    The present invention comprises a compact wooden display tower on a pedestal or base, and a rope. The display tower is preferably stained and finished to offer a pleasing presentation. The tower sits upright on the horizontal base. The display is designed to rest on a table. 
         [0026]    Distributed around the surface of the display tower are eyelets or hooks. These are preferably made of brass, or plated with brass, adding to the distinctive pleasing appearance of the device. The eyelets or hooks must be of a sufficiently adequate size such that the rope can pass through the openings within each eyelet or hook. 
         [0027]    Preferably the eyelets are positioned at varying heights from the base. This allows for several knots to be demonstrated at one time, and easily distinguished from each other by height above ground. 
         [0028]    Turning now to  FIG. 1 , a preferred embodiment of the present invention  100  is shown from a perspective view. The invention comprises a display tower  200 , a tower base  300 , and a plurality of eyelets  50 . One such eyelet  50  is shown attached to an optional latching device  500 . Device  500  has an eyelet at one end, which acts as a portable eyelet. Also shown is the rope  10  as used for demonstration of knot tying techniques. 
         [0029]      FIG. 2  displays a side view of a magnified portion of the same preferred embodiment of the present invention. Displayed in  FIG. 2  is a portion of the display tower  200 , rope  10 , and a plurality of eyelets  50 . Prominent in  FIG. 2  is the optional latching device  500 . Device  500  has an eyelet at one end, which acts as a portable eyelet. Thus, the operator (whose hand is shown) has just tied a knot around the portable eyelet. The latching device  500  is attached via its latching end to one of the eyelets  50 . The operator can detach device  500 , in order to move the knot  600  closer to an observer for detailed observation. This may be of especial use in a classroom situation. 
         [0030]      FIG. 3  displays another side view of the same preferred embodiment of the present invention. This is a less preferred view of the various components of the invention, including display tower  200 , tower base  300 , and a plurality of eyelets  50 . Also shown is the rope  10 , but latching device  500  is hidden behind tower  200 , and knot  600  is only partially visible. This would be a poor position from which to display knots, and the tying of knots. 
         [0031]      FIG. 4  shows the embodiment of the current invention from yet another side view. This is a good view of the various components of the invention, including display tower  200 , tower base  300 , and a plurality of eyelets  50 . Also shown are the rope  10 , and latching device  500 . This would be an alternate position from which to display knots, and the tying of knots, with respect to the preferred frontal view of  FIG. 1 . 
         [0032]      FIG. 5  illustrates detail of the spindle  400  for the collection of excess rope. The collection device need not take this form, and indeed the display tower will work for its intended purpose without any rope collection device whatsoever. However, it adds to the convenience of the display of knots to have a length of rope available, and a take-up spindle to store the length when not needed for display purposes. 
         [0033]      FIG. 6  images the embodiment of the current invention with the rope spindle  400  attached. This is a preferred embodiment of the invention, with its various components including display tower  200 , tower base  300 , and a plurality of eyelets  50 . Also shown is the rope  10 , but latching device  500  is partially hidden behind tower  200 , and knot  600  is barely visible. 
         [0034]      FIG. 7  shows the invention from the top, which is clearly not a good viewing position to observe the knot. The knot  600  is not visible, and is thus not a good viewing position for knot tying technique. 
         [0035]      FIG. 8  displays the bottom side  250  of base  300 . In the center of base underneath side  250  is a screw head  275 . This indicates a screw is used to attach base  300  to display tower  200 . Other attachment means are contemplated, such as nailing or gluing. Also contemplated is one-piece unibody construction, in which base  300  and display tower  200  constitutes a single body. 
         [0036]      FIG. 9  show further views of a preferred embodiment of the present invention from a front plan view. This view shows an excellent position for visualizing knot  600 , and the tying of the knot. This is a front perspective view. This would be a good viewing position in a classroom, a video, or even for a casual viewer interested in the tying of knots. 
         [0037]    While the invention has been described in connection with a preferred embodiment or embodiments, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
