DETAILED DESCRIPTION OF THE PREFERRED AND ILLUSTRATED EMBODIMENTS
(31) Turning now to
(32) According to the presently preferred embodiment, the sheath 14 may provide a pebbled texture 16 on its outer surface. The pebbled texture enhances grip and channels away moisture. This also enhances player performance in wet weather conditions. The material is preferably also temperature neutral so that it can enhance performance in cold weather conditions. The invention eliminates the need for tape and makes old lacrosse sticks look new again. Unlike tape, the invention does not leave behind any damaging residual adhesive. It also improves the safety of the stick as it provides a full sheath to protect the player from splintering wood shafts caused by checking during the game. The sheath can be quickly and easily removed from a lacrosse stick for use on another stick or it can be stored, e.g., in a pouch (not shown) until used again.
(33) According to preferred embodiments of the invention, the color of the sheaths and/or caps is coordinated to the desired team colors. The sheaths may also be imprinted with, e.g., team names, logos, slogans, inspirational sayings or advertising, etc. For example,
(34) Referring now to
(35) As before, the cap 612 and sheath 614 are preferably made from injection-molded rubber, synthetic rubber, neoprene or other synthetic plastic polymers that permit production in various thickness, colors and lengths. The elasticity of the material preferably gives it memory and durability. As before the sheath 614 is preferably cylindrical and is dimensioned to enable a friction fit on the shaft 11 of the lacrosse stick which, as shown in
(36) However, in this seventh embodiment of the invention as seen best in
(37) As further shown in
(38) The cap 610 is further modified to allow for relatively minor variations in configuration and dimensions of the sport shaft 11 on which it is mounted. More particularly, the tubular side wall 611 of the cup-shaped cap 612 in this embodiment has an octagonal cross-section which is dimensioned and configured to match the octagonal wall of the lacrosse stick shaft 11 so that it fits snugly over and on the octagonal end 15 of the shaft 11 and also in a friction fit manner. The outer portion of sidewall 611 of the cap 612 is provided with a plurality of spaced-apart fingers 618 which defined a plurality of longitudinally-extending slots 619 formed therebetween. The width of the fingers 618 are preferably dimensioned to generally match the width of the octagonal sides of the end of shaft 11 of the lacrosse stick which may vary and the slots 619 are similarly arranged so that they are generally aligned with the seven corners of the octagonal shaft 11. As can be appreciated, the fingers 618 and slots 619 allow some flexibility and sufficient clearance, if needed, if the general dimensions of the respective walls 611 of the cap 612 and shaft 11 are somewhat off relative to one another, thereby allowing the cap 612 to still fit on the end wall 15 of the shaft 11 despite any relatively small variations in its configuration or dimensions.
(39) The reinforcing ring 620 may be needed in situations where the cap 612 is not made of a sufficiently rigid plastic material to stand up to the radially-inwardly-directed force of the furled sheath 614 mounted thereon which might otherwise crush or cause the sidewall of cap 611 to buckle, preventing the end cap 612 from being fully mounted on the end 15 of the lacrosse stick 11, Obviously, if the cap sidewall 611 of the cap 612 is sufficiently rigid and strong enough to resist such deformation as may be caused by the furled sheath 614, the recessed section 617 and stiffening ring or collar 620 would not be needed.
(40)
(41) Turning now to FIGS, 18A-18E, 19A-19D and 20, therein illustrated in an eighth embodiment of the invention comparable to the seventh embodiment shown in
(42) End plug 730 is of the general type sold by Vertical Lax Inc. of Altamont, New York, which is solely used for locking the end cap 712 in a fixed, non-rotatable manner on the butt end 15 of the handle portion of the lacrosse stick 11, but in this invention it is used to also lock the sheath in place. More specifically, in the present embodiment end plug 730 of the hollow shaft employs a double step 733 consisting of lower step 735 and upper step 736, the latter of which is adjacent its head 732 for engagement with the end cap 712 and for assisting in the removal of the plug 732 when the sheath 714 is to be removed and replaced. In addition, in the present invention, the end cap head 713 has an outer bowl-shaped concave recess 715 in which the end plug head 732 is fully received when installed as more fully described below.
(43)
(44) As seen best in
(45) In this embodiment, the end cap 712 comprises an enlarged, rounded, generally donut-shaped end member or annular collar 713 defining an octagonal central opening 716 ringed by preferably, four spaced-apart resilient fingers 718 extending rearwardly therefrom. Fingers 718 are intended to be inserted into the cavity 13 of stick 11 and engage in a spring-like, biasing manner with the inner flap 714a (
(46) Furthermore, as further seen in
(47)
(48)
(49) As a result of this manner of engagement and construction, plug 730 creates an extremely rigid fixed cover assembly which will not twist in the user's hands which is extremely important during play. Moreover, plug 730 and the donut-shaped head portion 713 of end cap 712 are rigidly fixed upon the handle end 15 of lacrosse stick 11 in a manner which prevents user from injuring or slashing his/her hand on the free end 15 of the lacrosse stick which is typically made of metal today.
(50) As a result of the foregoing and in order to use this cover assembly 700, the user would initially unroll the rubber sleeve or sheath 714 from a coiled position (
(51) When it is decided to remove the sleeve 714 and replace it with another sleeve 714, the user would place an elongated tool, such as a screwdriver or the like (not shown), into the bowl-shaped recess 715 of the enlarged head 713 of the end cap 712 which recess 715 surrounds the plug head 732 and its neck portion 733. By manipulating the screwdriver flat head underneath the second step 736 of the plug 730 and then applying thereto an upward or outward pivoting action, the screwdriver flat head tip engages the second step 735. Then, a further rearward pivoting of the flat head pries the head 732 of the plug upwardly or outwardly so that the plug 730 would disengage from the end cap 712. At that point, the end cap 712 could then also be removed from the cover assembly 700 following which the sheath 714 could then be rolled up and removed. The process can be repeated whenever a new sleeve 714 is needed to be placed on the handle portion 721.
(52) As can be appreciated, various modifications may be made as will be apparent to those skilled in the art. For example, although the end caps are typically round or cylindrical, they could be configured to have a cross-section similar to that of the shaft on which it is mounted, such as octagonal for lacrosse sticks, although other shapes, such as round, oval, rectangular, or hexagonal are also sometimes used, such as for the shafts of other athletic equipment, such as ice hockey and field hockey sticks.
(53) In addition, although the sheaths 614, 714 of the cover may possibly have a thickness of about 1/16 to ¼ inches, the same can be varied to suit the particular use or application and/or the official sport regulations governing such equipment. In fact, it has been discovered that, most advantageously, the sheath may have a thickness less than ¼ of an inch and even less than 1/16 of an inch, Most advantageously, it has been found that the thickness of the sheath made of extruded rubber is preferably in the range of 0.010 to 0.050 inches and most desirably is about 0.030 inches.
(54) The sheath is preferably made from injection-molded, vulcanized rubber, neoprene of other polymers that permit production in various thicknesses, colors and lengths. The elasticity of the material preferably gives it memory and durability. The diameter of the sheath is preferably smaller than the diameter or width of the shaft of the athletic equipment employed so that it stretches to a tight fit. The enlarged end cap 613 preferably has a diameter of about 1 1/2 inches and the sidewall of cap 612 has a length of about 3 inches. The recessed inner portion is preferably about 1 ¼ inches in length and the outer portion of the sidewall is desirably about 1 ¾ inches with the slots having a length of about 1 inch. The cap end wall 613 preferably has an overhang of about ¼″ and a thickness or height of about the same. If a further disc-shaped or domed-shaped end piece (not shown) is used to create a neater appearance, it is desirable that the height of the end wall 613 and end piece does not exceed a maximum height of ¾″ and preferably, ½″ or less, so as not to appreciably extend the effective length of the stick 11. The end cap 712 and plug 730 can be of generally comparable dimensions. For example, the end cap 712 can have a length of about 1 ½-2 inches and the plug can have a similar length of about 1 ½-2 inches. The enlarged generally round or oval head 713 also preferably has a width of about 1 ½ inches.
(55) It should also be realized that although the cover 700 preferably includes both the end cap 712 and plug 730, for certain applications some benefits of the invention may also be achieved by utilizing just the end cap 712 (i.e., without plug 730), but without having a central opening 716 so it entirely covers the free end of the lacrosse stick like the cup-shaped embodiments previously discussed herein.
(56) Thus, while particular embodiments of the invention have been described, it is not intended that the invention be limited thereto, as it is intended that the invention be as broad in scope as the art will allow and that the specification be read likewise. It will therefore be appreciated by those skilled in the art that yet other modifications could be made to the provided invention without deviating from its spirit and scope as claimed.
