The present invention relates generally to lacrosse equipment, and more particularly, to a device for measuring a lacrosse head to determine whether the head complies with dimensional specifications.
Conventional lacrosse heads typically include an open frame having a ball stop joined with the base, a pair of sidewalls that extend from the ball stop, and a scoop that connects the sidewalls, opposite the ball stop. The sidewalls generally include a lower portion, such as a lower rim, that defines multiple circular or elliptical string holes. A lacrosse net is strung to the lower rim via the string holes, around the back side of the frame, leaving the opposing, or front side, side of the frame open for catching or shooting a lacrosse ball.
With improvements in technology and manufacturing techniques, lacrosse heads have evolved significantly over the past several years. Improvements have been made to increase the durability of a lacrosse head, through the use of new head materials, and to improve a player's ability to shoot, pass and otherwise control a lacrosse ball, through new head designs.
In 2007, the National Collegiate Athletic Association (“NCAA”) Men's Lacrosse Committee began an investigation to address issues related to the dimensions of currently available lacrosse sticks. Many committee members, and persons of interest in the lacrosse community, believed that the lacrosse heads at that time did not allow the lacrosse ball to come out of the head easily enough. In their opinion, this promoted more slashing, cross-checking, or contact with a lacrosse stick in the game to attempt to dislodge a lacrosse ball from the lacrosse head. This, in turn, allegedly created potential safety concerns related to excessive stick contact.
To remedy, or at least partially alleviate, these concerns, the NCAA Men's Lacrosse Committee proposed rule changes, scheduled to go into effect in 2010 (“Rules”). Among other things, the Rules specify minimum and maximum dimensions for both the head, stick and handle. While the Rules are applicable to NCAA competition, many other lacrosse organizations, from local leagues, to high school leagues, to youth leagues, adopt the Rules, greatly increasing the effect of the Rules on the dimensional requirements of lacrosse equipment in other layers of competition.
One of the new proposed Rules, Rule 1.17, addresses the minimum dimensional requirements between various portions of the sidewalls measured at a specific distance from the throat, also referred to herein as the ball stop. This Rule is further detailed at Appendix IV, of the Crosse Specifications of the NCAA Lacrosse 2008 Men's Rules and Interpretations, which provides: “Beginning Jan. 1, 2010, measurements for the crosse shall include the following, in addition to current specifications:”
In addition, Rule 1.17 requires the length of the head be a minimum of 10 inches from the outside edge of the head to the beginning of the throat. Although the above requirements are proposed, it is contemplated that the minimum distance between the narrowest point of the head at a measurement of 5 inches from the throat may perhaps change to 3.5 inches on both the front and the back; and at the widest point, the minimum distance will be 6.0 inches on both the front and back of the lacrosse head.
Thus, under the proposed Rules, a men's lacrosse head must be a minimum width of 3 inches at a location 1.25 inches from the throat, a minimum width of 3.0 inches between sidewalls at a location 3.0 inches from the throat, a minimum width of 4.0 inches on the front and 3.5 inches on the back at a distance of 5 inches from the throat, and a minimum width of 6.5 inches on the front and 6.0 on the back at the widest point of the lacrosse stick. The 1.25, 3.0, 5.0 inch and other dimensions are measured from the molded or wooden throat/ball stop of the frame of the lacrosse head, and not from a stop constructed of foam that is joined with the throat.
These dimensional requirements of the Rules allegedly prevent a player from using a stick that unfairly protects a ball within the pocket of the lacrosse head, thereby making it more difficult for an opponent to free the ball from the pocket. As an example, a lacrosse head with a width near its base that is only slightly larger than the diameter of the ball can provide an advantage in that it retains the ball in the pocket better than a head with a wider area near the base.
Ensuring that a lacrosse head complies with the dimensional requirements of the Rules will be difficult, particularly because a measurer or official will have to take multiple measurements at once. For example, to verify the 3.0 minimum width requirement, a measurer will first measure 3.0 inches above the throat, and then simultaneously measure across the width of the head on a line that is perpendicular to the 3.0 inch measurement. To take this measurement, the official will have to hold two rulers together perpendicularly and joined at a precise location. This will be a difficult task. Such measurements also may require an official who is engaged in strenuous athletic activity to carry around two or more rulers. Because of this, many officials may simply guess whether a head complies with the Rules. Accordingly, many illegal heads may go unchecked, which may promote unfair play in the game of lacrosse.
A device and method are provided to measure the dimensions of a lacrosse head. The device includes a longitudinal bar having a terminal end adapted to engage a throat of a lacrosse head, and at least one cross bar joined with and generally transverse to the longitudinal bar at one or more preselected distances from the terminal end. The cross bar can be configured to measure the width or other dimension of the lacrosse head at the preselected distances from the throat. Optionally, the cross bar can be generally perpendicular to the longitudinal bar.
In one embodiment, multiple cross bars can be positioned at different distances from the terminal end of the longitudinal bar to measure dimensions of the lacrosse head as prescribed by the Rules.
In another embodiment, first and second lateral cross bars are joined with and transverse to the longitudinal bar. The second lateral cross bar can be located at a distance farther from the terminal end of the longitudinal bar than a first cross bar is positioned from the terminal end of the longitudinal bar. Optionally, the first bar is positioned 1.25 inches from the terminal end, and when measured from end-to-end, is 3.0 inches. Further optionally, the second cross bar is positioned at 3 inches from the terminal end, and when measured from end-to-end, is 3.0 inches.
In yet another embodiment, the device includes a third cross bar that is joined with and transverse to the longitudinal bar at a distance farther from the terminal end of the longitudinal bar than both the first and second cross bars. This third cross bar can be at a distance of about 5.0 inches from the terminal end and dimensioned to be about 4 inches from end-to-end.
In a further embodiment, the longitudinal bar can extend beyond the third cross bar a preselected distance. This distance may be selected so that the total length of the bar from the first terminal end to a second terminal end opposite the first terminal end is at least about 10 inches in total length.
In still a further embodiment, the longitudinal bar can include indicia indicating a distance of 10 inches from the first terminal end for use in measuring the length of the lacrosse head to determine compliance with the Rules. Optionally, the longitudinal bar can define a window through which the head can be viewed, with the indicia being located adjacent the window to confirm dimensional compliance.
In yet a further embodiment, the device can include a slidable fourth cross bar that is joined with, but slidable relative to, the portion of the longitudinal bar extending beyond the cross bars. The fourth transverse cross bar can be dimensioned so that from one end to the other its width is about 6.0 inches so that it can measure the widest point of the lacrosse head.
In still another embodiment, the longitudinal bar can include indicia indicating a distance of 6.0 inches from the first terminal end for use in measuring the widest point of the lacrosse head to determine compliance with the Rules. Optionally, the longitudinal bar can define a window through which the head can be viewed, with the indicia being located adjacent the window to confirm dimensional compliance.
In another further embodiment, each of the first, second, third and fourth cross bars can be partitioned into independent arms or portions. For example, the first transverse cross bar can include a first arm and a second arm. The first arm and second arm can each be hingedly or pivotally joined with the longitudinal bar, and positionable in both a retracted position and an extended position. In a retracted position, each of the arms can lay adjacent the longitudinal bar, generally aligned with the length of the bar, and optionally within a periphery of the longitudinal bar. In the extended position, each of the arms can extend generally perpendicularly from the longitudinal bar. Optionally, the collective length of the first arm, second arm and width of the longitudinal bar between the arms is less than or equals the dimension desired to be measured on the lacrosse head.
For example, the first bar can include first and second arms or portions, which, when extended relative to the longitudinal cross bar, are of a dimension so that the total distance from a first end of one arm to a second end of the opposite arm is 3.0 inches.
In yet another further embodiment, the terminal end of the longitudinal bar can be configured as a semicircle, a triangular point, or an arc so that it can engage the throat of a lacrosse head at a point that is dead center of the throat (also referred to as a ball stop). Optionally, the terminal end can include a contact portion that extends upward or downward from the longitudinal bar, and that is designed to engage the ball stop or throat of the head during measurement. Further optionally, the terminal end of the bar can be configured to engage multiple points on the ball stop and/or sidewalls so that the longitudinal bar is centered along the longitudinal axis of the head and capable of measuring desired distances between the throat/ball stop and other points on the lacrosse head.
In yet another, further embodiment, the portion of the longitudinal bar extending between the third transverse cross bar and the second terminal end of the longitudinal bar can be void of any markings that denote distances from the terminal end or other portions of the device.
In yet another embodiment, the first, second and third cross bars of the device can be fixedly joined with the longitudinal bar, and the longitudinal bar and/or a cross member can include protrusions extending from a top or bottom surface of the device. These protrusions can be set apart from one another, or of a length corresponding to a dimension desirable to measure on the lacrosse head. For example, one protrusion can be positioned on a top side of the third transverse cross bar and can and include a first end and a second end, the first end and second end separated from one another by 3.5 inches. This protrusion can be used to measure a 3.5 inch dimension of the lacrosse head.
In yet a further embodiment, a method for using the device is provided in which the first terminal end of the longitudinal bar can be positioned with the terminal end engaging the throat/ball stop of the head, the longitudinal bar generally aligned along the axis of the head. The first, second, third and optional fourth transverse cross bars can be aligned with widths of the lacrosse head desired to be measured. Where the cross bar barely contacts, or does not contact, the sidewalls of the lacrosse head, a user can determine that the stick head is legal.
In yet another further embodiment, where the device includes collapsible arms, the user can position each of the arms in an extended mode before measuring the dimensions of the lacrosse head. This can be done manually or semi-automatically via a mechanism that extends the arms when the user engages the mechanism. Further, where the device includes a fourth transverse cross bar that is slidable relative to the longitudinal bar, the user can move the fourth transverse bar generally longitudinally along the axis of the longitudinal bar. The user can slide the fourth transverse cross bar toward or away from the first terminal end to determine whether the minimum distance between opposing sidewalls or between opposing portions of the scoop of the lacrosse head satisfy minimum dimension requirements.
Even further optionally, where the device includes indicia or projections to measure certain dimensions perpendicular to the longitudinal axis of the lacrosse head, the device can be rotated relative to the axis of the head so that the indicia or protrusions properly align with the dimension to be measured.
The device and method described herein enable lacrosse officials and others to quickly and accurately measure the dimensions of a lacrosse head. Where the device includes collapsible portions, the device is quickly and easily convertible to a configuration that can be carried by a game official in a pocket or elsewhere.
These and other objects, advantages, and features of the invention will be more fully understood and appreciated by reference to the description of the current embodiment and the drawings.
As shown in
The frame 112 also can define net securing structures 124 to enable attachment of the netting (not shown) to the head. The lacrosse head 110 can define a socket 128 that extends generally rearward from the throat 114 of the frame 112 for attachment of a handle (not shown) or element.
As shown in
As shown in
In general, the upper rims 132, 134 define the uppermost surfaces of the sidewalls 116, 118, while the lower rims 144, 146 define the lowermost surface of the sidewalls 116, 118. Optionally, the upper rims 132, 134 and lower rims 144, 146 may be a single integral structure, or may be rails separated by apertures.
The frame element 112 described herein is merely illustrative of known lacrosse heads 110 for use in describing the lacrosse head measurement devices in accordance with the current embodiments below.
A current embodiment of the lacrosse head measuring device of the present invention is shown in
The longitudinal bar 20 can also include indicia indicating a specified distance from first terminal end 13 to the indicia so that the device 10 can be used to measure the minimum overall length of a lacrosse head from the ball stop, which under current Rules, is 10 inches. Optionally, the longitudinal bar can define one or more windows 63, 64 with indicia 65, 66 adjacent the windows, so that a portion of the frame can be viewed through the window and compared against the indicia 65, 66 to determine compliance with dimensional specifications, such as those specified under the Rules. As illustrated, the indicia 65 indicates a distance of 6 inches or 6.5 inches and the indicia 66 indicates a distance of 10 inches from the first terminal end 13.
As shown in
For example, the Rules specify the minimum dimensions between the inner surfaces of the sidewalls 116, 118 measured at a specific distances from the throat 114. With reference to
The lacrosse head measuring device of the current embodiments can quickly and easily assist a user in determining whether a lacrosse head is compliant with all, or a portion of, the proposed dimensional width and length requirements of the Rules, or other specifications as desired.
As used herein, the term “bar” refers to any generally elongate member or element that spans a distance from one end to the other. A bar can be segmented into different portions, and those portions can be fixed or moveable relative to one another or to other bars or other components of the device, such as the longitudinal bar.
As used herein, the term “Rules” refers to the current or proposed rules regarding dimensions of lacrosse head mandated by the NCAA, where the proposed Rules are scheduled to become effective Jan. 1, 2010. The Rules are incorporated by reference in their entirety herein.
With reference to
Generally, the shape of the first terminal end 13 can be such that it decreases in width as it extends toward the end. This decreasing width configuration enables the device 10 to be positioned adjacent the throat 114 of the lacrosse head without interfering with the remainder of the throat 114, the foam stop 122, or sidewalls 116. Optionally, the decreasing width or the reference post 15 can compress the foam stop 122 so that the first terminal end 13 engages the throat 114 to provide accurate measurements. More generally, the first terminal end 13 can be somewhat pointed so that it enables an official to compress a foam stop, which is regularly found on most lacrosse heads, so that the actual measurement can be taken from the plastic frame of the throat 114, rather than offset by the depth of the foam stop.
As shown in
The second transverse cross bar 40 can include opposing third and fourth ends 42 and 44. These third and fourth ends 42 and 44 can be joined with and form terminal points of the second transverse cross bar arms or portions 46 and 48. The ends 42 and 44 can be pointed as shown, or of any other geometric configuration, such as those described in connection with the first terminal end 13 of the longitudinal bar 20 above. The illustrated arms 46 and 48 can be configured to move relative to the longitudinal bar 20, as explained further below, or can be stationary, and integrally formed with the longitudinal bar. The ends 42 and 44 of the second transverse cross bar can be separated by about 3.0 inches, and can be configured to measure the widths W2 and W5 between opposing portions of a lacrosse head 100 at distance d2, with reference to
The third transverse cross bar 50 can include opposing fifth and sixth ends 52 and 54. These fifth and sixth ends 52 and 54 can be joined with and form a terminal points of the third transverse cross bar arms or portions 56 and 58. The ends 52 and 54 can be pointed as shown, or of any other geometric configuration, such as those described in connection with the first terminal end 13 of the longitudinal bar 20 above. The illustrated arms 56 and 58 can be configured to move relative to the longitudinal bar 20, as explained further below, or can be stationary, and integrally formed with the longitudinal bar. The ends 52 and 54 of the third transverse bar can be separated about 3.5 inches or about 4.0 inches, and configured to measure the widths W3 and/or W6 between opposing portions of a lacrosse head 100 at distance d3, with reference to
The transverse cross bars can be movable so that the device may be operable in both an extended mode and a collapsed mode. Generally, in the extended mode, all of the arms 36, 38, 46, 48, 56, 58 are extended so that the device 10 can be used to measure or evaluate the dimensions of a lacrosse head 110 as shown in
Generally, when extended, each of the transverse cross bars 34, 40 and 50 can lie on respective transverse axes 230, 240 and 250 which are perpendicular to longitudinal member axis 21 at 1.25, 3.0 and 5 inches from the first terminal end 13, respectively. Of course, these transverse axes can lie at different distances from the first terminal end as desired.
Optionally, the position and dimension of the transverse cross bars 30, 40 and 50 can be altered depending on the particular Rules for which the measuring device 10 is designed, for example, men's lacrosse rules, women's lacrosse rules and other competitive rules.
Optionally, the actual dimensions of the cross bars 30, 40, 50 can include a portion of the longitudinal member. For example, with reference to
Referring further to
As shown in
The cross bars 30, 40 and 50, when pivotable or movable relative to the longitudinal member 20, can be positioned generally on a front side 25 of the longitudinal bar 20. If desired, the cross bars 30, 40 and 50 can be positioned inside a cavity (not shown) defined by the longitudinal bar so that the pivot points of the respective arms are protected from the environment. Optionally, the cross bars 30, 40 and 50 can be staggered on opposite front and rear surfaces of the longitudinal bar 20 as desired.
With reference to
The longitudinal bar can also define windows 63 and 64 beyond the transverse cross members 30, 40 and/or 50. The window 63 can be configured so that the user can peer entirely through the longitudinal member 20, and see a portion of the lacrosse head 110 when conducting measurements. The other window 64 likewise can be configured. Adjacent the windows, indicia 65 and 66 can be located. The indicia 65 can indicate distances of 6 inches and/or 6.5 inches from the terminal end 13 to comply with the Rules, while the indicia 65 can indicate a distance of 10 inches from the terminal end 13 to measure a minimal length of the head as prescribed by the Rules.
Optionally, the longitudinal member 20 can be void any windows, and the respective indicia for different dimensional requirements can be positioned adjacent the sides of the longitudinal bar so that the bar can be used much like a ruler. Further optionally, the windows can be filled with a clear material or a portion of the longitudinal bar near the second terminal end 14 of the longitudinal bar can be transparent, with the appropriate measurement indicia marked across the clear material to take desired measurements.
The device 10 and its various components can be constructed from a solid steel or aluminum plate, or optionally from synthetic materials such as plastic. Other suitable materials are those which do not expand or contract due to temperature change. One possible material is a polycarbonate such as LEXAN®. The depth of the device can be about ⅛ inch, ¼ inch, ½ inch, 1 inch, or greater, or less, depending on the application.
The manufacture and use of the measuring device of the current embodiment will now be described. The device 10 can be molded or extruded from a plastic or other synthetic material in the desired shape.
More particularly, the longitudinal member 20 and the other components, for example, the cross members and respective arms or portions of those cross members 30, 40 and 50 can be molded from a plastic material, for example, polycarbonate. The components can be molded in the desired configuration. After the components are molded, they can be assembled. For example, each of the independent arms of the embodiment shown in
Where the longitudinal member 20 optionally includes first and second parts 24 and 29, those parts can be joined together at the hinge 27 or other connection element as desired. The components of the device 10 can be marked with indicia using screen printing or other processes as desired to indicate the respective measuring dimensions. With the device assembled and including the appropriate indicia and/or other markings, the device 10 can be folded to the completely collapsed mode as indicated in
In other embodiments, where the device 10 is constructed from a sheet of steel or aluminum or other metal, or some other synthetic material (such a fiberglass, plastic or carbon), the device can be machined or cut from that material. The machining or cutting results in the components of the device being configured as desired. Further assembly can be performed to complete the device 10. Optionally, after the device 10 is manufactured, the it can be drilled with multiple holes to remove excess material and reduce weight even further.
In operation, the device is generally retrieved from a storage location, for example, a user's pocket or a storage compartment. The device, when stored, is typically stored in the collapsed mode. Thus, the user will convert the device 10 from the collapsed mode to the extended mode, in which the components of the device are moved in the opposite direction of the arrows 127 and 128 in
For example, in the embodiment shown in
If the user desires to measure the ball receiving area of the head to ensure compliance with other dimensional requirements of the Rules, then the user can move the device 10 to the ball retaining area and align the different components as illustrated in
Where the device includes windows 63 and 64, the indicia 66 can be referenced against the top of the lacrosse head to determine whether or not the head complies with the minimum measurement of 10 inches, as required by the Rules. For example, the user views the frame element 112 through the window 64 and compares the boundary of the frame element 112 within the window relative to the indicia 66. Depending on the prescribed Rules, the user can determine whether or not the head is in compliance or not in compliance with the dimension specifications.
Where the device 10 includes the optional window 63 and other indicia 65 for other measurements, the device can be used to measure or determine compliance with other dimensions of the Rules. For example, a user can determine the minimum width of the ball receiving area and the ball retaining area by placing the reference post 15 and/or the terminal end 13 against the sidewall, with the longitudinal axis 21 generally transverse, and more specifically, perpendicular to, the longitudinal axis 125 of the lacrosse head 110. The user then views the frame element 112 through the window 63 and determines where the inner surface of the ball retaining area falls relative to the respective indicia 65. In this manner, the user can measure front of the head 110 to determine whether the minimum width of the ball receiving area is 6.5 inches as provided by the Rules. To check the ball retaining area, the user can move the device 10 to the opposite (rear) side of the head 110 as shown in
As shown in
The arms are coupled to one another with a movement transferring mechanism 755, 745 and 735. As illustrated, those mechanisms are generally geared or tooth portions of the respective inner portions of the respective transverse cross bars. The gears mesh with one another so that movement of one arm results in corresponding movement of the other arm from a collapsed mode to an extended mode, or vice versa. Of course, different mechanisms may be substituted for those shown in
In general, the rack gear 824 includes geared surfaces 823 and 825 which directly and indirectly engage the respective gears 857 and 859; 847 and 849; and 837 and 839 of the respective cross bars 850, 840 and 830.
With the first transverse cross bar 830, the movement of the respective bars 836 and 838 is generally opposite of the movement of the rack gear 824. Accordingly, counter gears 826 and 828 are interposed between the rack gears 823 and 825, and the respective gears 837 and 839 on the arms 836 and 838. Accordingly, the movement 829 translates to the movement shown by the arrows adjacent the arms 836 and 838. The measuring device can be reconfigured from the extended mode to the collapsed mode simply by reversing movement of the rack gear 824. Other mechanisms may be substituted for the rack gear to simultaneously move all the arms of the respective cross bar as desired.
With reference to
A fourth embodiment of the device, shown in
The cross bar 1060 of this alternative embodiment can be 6.5 inches or some other length, and can be used to ensure compliance to determine whether or not a particular head complies with a minimum width of 6.5 inches on the front of the lacrosse and 6 inches on the back of the lacrosse head, or any other dimension. As described in the embodiments above, the fourth cross bar 1060 is moved upward and downward (toward or away from the throat of the head). As long as the width of the respective ball receiving portion and ball retaining portion (adjacent the cross bar 1060 as it moves) are greater than the width W18 of the device 1010, then the head is compliant with the respective portion of the Rules. As desired, other mechanisms may be used to join the fourth cross bar 1060 with the longitudinal bar 1020 and provide the desired movement of it relative to the bar 1020.
The above description is that of the current embodiment of the invention. Various alterations and changes can be made without departing from the spirit and broader aspects of the invention as defined in the appended claims, which are to be interpreted in accordance with the principles of patent law including the doctrine of equivalents. Any reference to claim elements in the singular, for example, using the articles “a,” “an,” “the” or “said,” is not to be construed as limiting the element to the singular.
This application claims benefit of U.S. Provisional Application No. 61/080,040, filed Jul. 11, 2008, and U.S. Provisional Application No. 61/083,850, filed Jul. 25, 2008, both of which are incorporated by reference herein.
