BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to athletic field boundaries, and more particularly to a portable and adjustable field boundary that includes markers and retractable boundary marking tape or cord and that allows almost infinite adjustment and configuration of the adjustable field boundary.
2. Background and Related Art
Many sports use a playing field or surface on which a large part of the action of the sport occurs. Often, the field or surface has defined boundaries, where certain events must take place within the boundaries, or certain events that take place outside the boundaries require certain effects. For example, in basketball and soccer, the ball must stay within the boundaries of the court or field, or if the ball crosses outside the court or field control of the ball is turned over to the team which was not the last team to touch the ball. In volleyball, the server must strike the ball from behind the back boundary, while whether a point is earned or the serve changes is usually determined by whether the ball touches the ground inside or outside the boundary in conjunction with which team last touched the ball.
Unfortunately, while many people enjoy playing sports, many sports are often limited in where they can conveniently be played. For example, in the United States, soccer is most often played by large teams on large dedicated fields of grass with defined boundaries painted or cut into the grass. If a smaller group of players desires to play, they often find themselves using a large field without a properly-defined boundary, or they just play in an area without boundaries at all. Similarly, people often go to the beach and set up a volleyball, badminton, or similar net, but just dig marks in the sand for boundaries that are quickly obliterated during the game, or the people do not even try to establish clear boundaries of what is out and in. This kind of informal play can lead to tension between the players such as when a dispute occurs as to whether a ball was in or out.
Furthermore, even if people have some sort of boundary system that they can take with them to set up a smaller field for soccer or to more clearly define the boundaries of their playing surface, different sports often use fields of different sizes and shapes; the boundary that works for one sport typically does not work for another. Thus the recreational sport player, the one who tends to have the least amount of money to spend on properly defining boundaries, is forced into buying multiple costly setups for each of the sports in which he or she desires to participate. Even assuming the player has the means to purchase multiple different boundary systems, the player must also have the space to store all the different systems, which can quickly grow burdensome.
Coaches of teams have related problems. For example, in football, a coach often desires a defined area or delineated space in which the players in training should run their routes, a so-called football lane. Also, in soccer, it is not uncommon for a coach to divide the team up into several mini games in areas smaller than the whole field so that several players at once can practice their skills. In such cases, a coach might instruct a set of players to go make a twenty yard by twenty yard box and practice passing or shooting in that defined area. Confused players do their best but don't often end up with a well-defined area that satisfies the coach's intended wishes.
BRIEF SUMMARY OF THE INVENTIONThe following description is provided so that the features and advantages of the invention may be readily understood. The description should not be deemed limiting of the scope of the invention, but the scope should be determined by reference solely to the appended claims.
The embodiments of the present invention provide a modular portable adjustable boundary system. A low-profile and portable marker contains a flexible extendible boundary marking tape or cord that may be extended whatever distance is desired, up to the end of the tape or cord, and attached to another marker or even to the ground. If attached to another marker, the tape or cord of that marker may then be extended as desired and attached to another marker, and so on, until the tape or cord of a subsequent marker returns and is attached to the first marker, thus enclosing and defining the boundary of an athletic field or surface. As used herein, the word “field” means an athletic field, court, surface, or other athletic area where it is advantageous to have a boundary or other line marked.
The marker may be designed so that the tape or cord rests close to the ground so as not to interfere with the playing of a sport in the bounded area. Also, the marker may be designed to provide frictional attachment to the ground or surface of the area bounded and to be played upon, or may be staked into the surface if the surface allows. If staking is not possible and/or additional friction is desired to hold the marker in place, a skirt may be attached to provide additional support.
The tape or cord may be automatically retractable or may be manually wound and unwound as desired, and a means for locking the position of the tape or cord may be provided. The tape or cord may also be provided with markings showing the distance the tape or cord has been extended or showing the location of placement of additional game elements, such as a soccer goal, midline, net, or basketball standard.
The marker is self-contained, inexpensive to produce and own, and almost infinitely expandable. The marker is small and light enough that several may be carried by a single person in a bag or backpack, providing ready portability. Additionally, the marker may be manufactured in a stackable format and multiple markers carried in a dedicated carrier. Setup and takedown of an athletic boundary using the marker system is rapid and simple, lending itself to use in a variety of situations, such as training situations, informal spontaneous games, and formal team sports.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGSThe objects and features of the present invention will become more fully apparent from the following description and appended claims, taken in conjunction with the accompanying drawings. Understanding that these drawings depict only typical embodiments of the invention and are, therefore, not to be considered limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
A description of the embodiments of the present invention will be given with reference to the Figures. It is expected that the present invention may take many other forms and shapes, hence the following disclosure is intended to be illustrative and not limiting, and the scope of the invention should be determined by reference to the appended claims.
Referring now to
Disposed or wound about the body 42 of the illustrated embodiment of the marker is a boundary marking tape 46 that may be unwound or extended from the marker to delineate a boundary for an athletic field. Thus the body 42 may be of any size or shape that allows for disposing the boundary marking tape 46 around the body 42 in a storage position, and the top and base 44 may similarly be of any sizes or shapes that serve to contain the boundary marking tape 46 on the marker when in the storage position. Exemplary fields and courts for which the boundary marking tape 46 and marker may mark a boundary include a soccer field, football field, badminton court, basketball court, volleyball court, rugby field, or any number of other fields or courts where a visible boundary line is desirable. Other sports for which the inventive portable adjustable marker and boundary system might be desirable include baseball, softball, kickball, ultimate Frisbee, and any other number of formal and informal sports, as one skilled in the art can readily recognize.
One informal sport with which the marker and boundary marking tape 46 may be useful is street soccer, where small groups of people get together and, often spontaneously, decide to play a game of soccer in a small area, sometimes a parking lot or street. In such situations, the informal and spontaneous nature of the game dictates that the time necessary to locate a suitable grassy area with marked boundaries on which to play is not available. In such situations, the various embodiments of the present invention advantageously allow the players to rapidly set up a marked field on which to play. While children and adults worldwide engage in such games, until now they have not had the ability to rapidly set up proper boundaries for their games, and they have often been forced to play without well-defined boundaries. Embodiments of the present invention provide the ability to quickly and easily define boundaries for such games and also provides easy portability as several of the marker/tape systems can easily be thrown in a bag, backpack, or car and thus be available at any time and place.
As can be readily appreciated by reference to
As can be readily appreciated, the inventive boundary marking system as provided is extremely flexible in use, as can be seen in
The boundary marking tape 46 used in various embodiments of the present invention may be of a number of different materials known in the art or later created, but it is anticipated that the boundary marking tape 46 should be relatively thin so as to allow a reasonable length to be wound about the body 42 without requiring a marker of extremely large width or weight. The boundary marking tape 46 may be of differing widths so as to suit the needs and fancies of different customers buying the marker system. The boundary marking tape 46 may be manufactured of a highly visible material to aid in demarcating the boundary, and may also be customizable with printing suited to advertise the manufacturer of the system, or even to suit the fancy of the purchaser or user.
It is also anticipated that the boundary marking tape 46 might be manufactured to include a glow-in-the-dark material so that game play may extend past dusk while the boundary marking tape 46 continues to clearly show the boundaries of the playing field. Alternatively, the boundary marking tape 46 may incorporate reflective markers attached to the tape to provide an easily-visible boundary, even in low-light or oddly-lit situations. The boundary marking tape 46 might even have woven into it small LEDs and wires so as to allow the tape to actively glow at night, allowing a heretofore unknown expansion of games such as soccer when using a lit ball, for example. The marker itself might also have battery-powered LEDs placed in it, even if the boundary marker tape 46 does not have LEDs but just a passive glow system or no lighting system, to provide lit corners for the system and extend play. As can be seen from this description, the boundary marking tape 46 may be widely varied to enhance its particular functionality as desired.
One way in which the boundary marking tape 46 may be advantageously modified is to provide special markings on the boundary marking tape 46 corresponding either to the extended length of the boundary marking tape 46 or the anticipated location of objects to be placed on the extended boundary marking tape 46, such as a goal. By marking the boundary marking tape 46 with distance markings, the system may easily be used to provide varying field sizes of desired and known side lengths. For example, if a field or area fifteen yards long and ten yards wide is desired, but each marker contains twenty yards of boundary marking tape 46, no special measurements are necessary to get a field of the proper size. Instead, rather than unwinding or extending the full length of boundary marking tape 46 for each marker, the boundary marking tape 46 of two markers may be extended or unwound to the ten yard mark on the boundary marking tape 46 to form two sides opposite one another. Meanwhile, the boundary marking tape 46 may be extended or unwound to the fifteen yard mark on two other markers to form the two orthogonal sides, and the field may thus be set at the desired size. Fields or areas of any size can be similarly provided. Marks such as this (tic marks, for example) may be provided every yard, every foot, every meter, or at any desirable distance on the boundary marking tape 46.
Various features may be added to the marker depicted in
Sometimes, it may be desirable to have the boundary marking tape 46 extend from the marker in the vertical orientation shown in
In use, the boundary marking tape 46 of the marker may be extended to a desired length in the vertical orientation shown in
In a manner alternative to the hook 52 of
It is sometimes desirable to provide a means for further securing the placement of the marker. Such means may include providing at least one spike to secure the marker to the ground when the ground is soft, or it may include an increased surface area to provide further frictional contact with the playing surface.
Referring back to
Sometimes, such as in use on an interior floor or on a hard exterior surface such as asphalt or concrete, it is desirable to hold the marker in place more securely than may be achieved using the friction of the bottom surface of the base 44 of the marker. In such instances, a skirt 62 may be used to provide a larger frictional surface to interact with the ground and hold the marker in place. An embodiment showing a skirt 62 is shown in
In this type of use, it may be desirable to have the skirt 62 designed to be placed over the marker after the boundary marking tape 46 has been extended, while in other designs it may be desirable to allow the skirt 62 to be placed before extending the boundary marking tape 46. In other designs, it may be desirable to place the skirt 62 on the ground first and to then attach the marker. Other potential methods of providing an increased-surface-area skirt 62 to provide more stable contact with the ground are also encompassed by the embodiments of the present invention. The skirt 62 may be provided in pieces or may be foldable to provide for compact transportation and storage, and then may be assembled or unfolded around the marker when used.
It is envisioned that the embodiments of the present invention could bring about a large change in the way some sports are played in the United States and elsewhere. For example, in the United States, soccer is generally played with large teams on grassy surfaces, and teamwork is so emphasized that many players do not acquire the individual skills often acquired by international players who start as children playing soccer in the street one-on-one or in small groups. Using the embodiments of the present invention, possibly with a skirt 62, a large soccer tournament may be held in an open parking lot, similar to the street basketball tournaments commonly held now. Small teams of two to four could compete, gaining the individual one-on-one skills often had by international players. This could also help to raise the profile of soccer in the United States, as such tournaments often occur in very visible places and attract much attention.
Turning now to the manner of winding and unwinding, or extending and retracting, the boundary marking tape 46, it is envisioned that several different methods and means of providing this extension and retraction could be provided. For example, one simple way to provide for an extensible boundary marking tape 46 may be as in
Alternatively, the marker of
In such a system, a lock may be provided to lock rotation of the rotating portion of the body 42 relative to the rest of the marker, so as not to retract the boundary marking tape 46 when not desired. Alternatively, the upper cone 40 or top may be integrally designed with such a lock so that when the boundary marking tape 46 is extended as desired the upper cone 40 or top is pressed down and/or turned to lock the boundary marking tape 46. In this pop-up/press down configuration, the pressing down of the upper cone 40 provides an additional advantage of putting the marker in a configuration with a lower profile less likely to be in the way of game play. Alternatively, the rotating portion of the body 42 may be provided with a ratcheting system so that the rotating portion automatically locks when the boundary marking tape 46 is extended, and then releases under some other stimulus. For example, a release button may be provided on the top or bottom of the marker, or even inside the center hole 60, to prevent accidental retraction. Alternatively, the ratcheting lock may be released by a small further extension that resets the ratchet lock. Other methods commonly used to provide for locking and release as known in the art are also encompassed by the various embodiments of the invention.
Another method providing for retraction or winding of the boundary marking tape 46 could be to provide a handle or crank attached at the base 44 or upper cone 40 that rotates with the marker or with the rotating portion of the body 42. A reciprocal grip that does not rotate may optionally be placed on the base 44 or upper cone 40 so as not to interfere with the rotating of the handle and may provide a place to grip and provide stability during winding. The handle may be designed to flip out into a winding position, and flip back into a recessed position when winding is completed. Thus, when retraction is desired, the handle may flip out, the user may then grasp the handle in one hand and the grip in the other, and the user may then wind the boundary marking tape 46 back into the marker. The handle may then be flipped back into the recessed position to provide compact storage of the marker.
While the boundary marking tape 46 described above provides some advantages in visibility of the demarcated boundary, it is anticipated that the boundary marking tape 46 may be replaced with a string, cord, or cable without changing the overall functionality of the illustrated embodiments of the invention. Thus any of a variety of extensible elements may be advantageously used. In fact, a string, cord, or cable provides certain advantages in certain situations. For example, the issue with twisting from a vertical storage position to a horizontal use position encountered with a tape version of the extensible element is eliminated and the main desire to be satisfied in most circumstances is keeping the string, cord, or cable close to the ground. As another example, in some instances it may be possible to wind a longer distance of the string, cord, or cable about the body 42 of a marker than would be possible with the boundary marking tape 46 in a package of the same size since the string, cord, or cable is able to wind up and down the body 42, potentially even up inside the upper cone 40 or top.
The various embodiments of the present invention have the advantages described above as well as other advantages, and it is anticipated that one of skill in the art can readily appreciate by practicing the invention the many advantages to be obtained from the embodiments of the invention. The described embodiments of the portable adjustable boundary marking system provide advantages for use by organized teams and informal get-togethers alike. Coaches who want drills set up, such as to practice three-on-three soccer drills, or running in certain football lanes, can use the embodiments of the present invention to clearly delineate where their players should go and be. Children at school can easily bring several markers in a backpack and set up a playing field during recess with time to spare for actually playing a game. Sports that were limited in where they could be played before may be played in almost any environment with only minimal time required for setup and takedown, by using the embodiments of the present system.
The present invention may take other forms without departing from its spirit or essential characteristics. For example, it may be desirable to provide a flag in conjunction with the marker described. To do so, a flag may be unitarily provided as a part of the center hole spike described above, securely anchoring the marker and flag. Alternatively, a flag may be provided through the center hole 60 or otherwise attached to the marker without use of a center hole spike; if the center hole 60 is not being used with a center hole spike, the center hole may be used as a receptacle to receive an inserted removable flag, for example. Similarly, if a skirt 62 is used, the skirt 62 may also be provided with a flag that passes through the center hole 60 described above. In some embodiments and situations where a flag is desired, the upper cone 40 may be removed completely, and replaced with a flag that serves as the top of the marker.
While the marker has been depicted as being round and of a low profile, in some instances the marker may desirable take other shapes, such as square or arbitrarily or decoratively fanciful shapes for certain situations. In some cases, the marker may be advantageously designed to take a much larger profile, such as when a longer boundary marking tape 46 or cord, string or cable than may be provided in a smaller, low-profile marker is desired.
It may also be advantageous in some situations to provide multiple boundary marking tapes 46 in the same marker to allow more flexibility in boundary design. For example, if two boundary marking tapes 46 are provided in a marker such as the central marker in the long boundary side in
While it is anticipated that one of the advantages of the portable adjustable boundary marking system is its light weight and compact package, various means might be used to further secure the boundary marking tape 46 in place. For example, small weights might be provided with the boundary marking tape 46 to make it resistant to movement in the wind and help keep it close to the ground if the ground is somewhat irregular. Alternatively, wickets, securing spikes, or other anchors could be used when the playing surface is soft enough to allow their use. Thus it may be seen that the embodiments of the present invention are readily modifiable to suit a variety of situations and needs.
Referring now to
In addition, the base or bottom of the marker has been provided with several microspikes 66 that enhance the stability of the marker when placed in contact with the ground, as discussed above. While the marker shown in these figures has been configured to accept a relatively broad boundary marking tape 46, one of skill in the art can readily appreciate that, in some embodiments, narrowing the boundary marking tape 46 may further enhance the low-profile nature of the shown embodiment as the corresponding height of the marker would decrease.
