Description




FIELD OF THE INVENTION




The invention relates to an extensible leg pad for use as protective gear in contact sports, especially hockey.




BACKGROUND OF THE INVENTION




Hockey leg protectors conventionally have a flexible elongated padding liner positionable around the front of user's leg from the ankle to above the knee (note that common terms such as “shin guards” or “shin pads” are therefore slightly misleading since protection for the knee is also provided). Rigid or semi-rigid shield members such as rigid plastic knee shield and rigid plastic shin shield are sewn or riveted to the padding liner. The knee shield moves with the knee when the user flexes his leg simply by the flexibility of the padding liner. Usually, the length of the leg pad is fixed, but some prior pads allowed adjustments in length.




U.S. Pat. No. 5,732,411 discloses a protective pad having two adjustable portions which may be secured together at varying relative positions in order to adjust the pad length. More particularly, the pad includes an upper sliding section and a lower sliding section which comprises a mateable portion. The upper sliding section comprises a knee protector and a base portion which comprises a mateable portion including openings. The base portion has an opening which is similar in size and configuration to the openings of the mateable portion. These openings can be brought into registry with the opening of the base portion and an element can then be inserted for locking the two sliding sections in place.




U.S. Pat. No. 5,652,956 discloses an adjustable shin pad having a lower portion slidable with respect to an upper portion by virtue of one or more slotted holes in either or both of the upper portion and/or lower portion. Bolts and T-nuts are used in the slots to secure the upper and lower portions together.




Canadian Patent No. 647,906 discloses a leg pad comprising a knee guard, a shin guard and an instep guard with flexible portions. The flexible portion located between the knee and shin guards comprises additional sets of eyelets which may be aligned with the corresponding opening in the shin guard. Thus, to make the leg guard shorter or longer, different eyelets may be aligned with the openings for securing the flexible portion to the shin guard.




While these prior pads provide length adjustments, they require use of bolts, screws, nuts or another element for adjusting the length of the pad and for securing together the two adjustable sections of the pad through registry of slots or openings.




Thus, there is a need in the industry for a pad which provides an easier way to adjust and secure together the different adjustable portions of the pad.




It is an object of the present invention to provide an extensible leg pad including an upper portion comprising a knee shield for covering a substantial part of a front surface of user's knee and a first shin shield along and partially around user's shin, said knee shield and said first shin shield being secured to an upper padding liner positionable over the knee and along and partially around the shin, a lower portion comprising a second shin shield along and partially around the shin which is secured to a lower padding liner positionable along and partially around the shin, said first and second shields having respective first and second overlapping surfaces, and a belt for securing together said upper and lower portions wherein said upper and lower portions allow adjustment of the overall length of said pad, and said belt is responsive to tension for pressing said overlapping surfaces together at a contacting area.




It is a further object of the present invention to provide an extensible leg pad including an upper portion comprising a knee shield for covering a substantial part of a front surface of user's knee and a first shin shield along and partially around user's shin, a lower portion comprising a second shin shield along and partially around the shin, said first and second shields having respective first and second overlapping surfaces, and a belt for securing together said upper and lower portions wherein said upper and lower portions allow adjustment of the overall length of said pads and said belt is responsive to tension for pressing said overlapping surfaces together at a contacting area.




It is a further object of the present invention to provide an extensible leg pad including an upper portion comprising a knee shield for covering a substantial part of a front surface of user's knee, a lower portion comprising a shin shield along and partially around a user's shin, said knee and shin shields having respective first and second overlapping surfaces, and a belt for securing together said upper and lower portions wherein said upper and lower portions allow adjustment of the overall length of said pad, and said belt is responsive to tension for pressing said overlapping surfaces together at a contacting area.




In a preferred embodiment of the present invention, the first shin shield of the upper portion and the second shin shield of the lower portion comprise overlapping surfaces having a portion made of rubber, and such a pad further includes a belt having a strap with loops and hooks sections for securing together the upper and lower portions at the contacting area.




In another embodiment of the present invention, the first shin shield of the upper portion and the second shin shield of the lower portion comprise overlapping surfaces having a portion that includes toothed section capable of interlocking together with positive engagement these sections, such a pad further includes a belt having a strap with loops and hooks sections for securing together the upper and lower portions at the contacting area.




Other objects and features of the invention will become apparent by reference to the following specification and to the drawings.

10


. The pad


10


includes an upper portion


12


comprising a rigid knee shield


14


for covering a substantial part of a front surface of user's knee and a first rigid shin shield


16


along and partially around user's shin. The knee shield


14


, is secured to a knee padding liner


18


which partially wraps the knee and the shin. The first rigid shin shield


16


is secured to a first shin padding liner


20


which partially wraps the shin.




The pad


10


further includes a lower portion


22


comprising a second rigid shin shield


24


along and partially around the shin. The second rigid shin shield


24


is secured to a second shin padding liner


26


which partially wraps the shin. The first and second shin padding liners


20


and


26


are designed in order that an upper portion of the second shin padding liner


26


overlaps a lower portion of the first shin padding liner


20


when the upper and lower portions


12


and


22


are secured together.




The pad


10


also includes a strap assembly


52


. The strap assembly


52


comprises a hook


54


secured on one side of the pad


10


, a ring


56


secured on the other side of the pad


10


and an adjustable strap


58


. As best seen on

FIGS. 4 and 5

, the adjustable strap


58


has a loop


60


at one end and loops and hooks sections


62


and


64


. In use, the end of the strap


58


is passed through the ring


56


and once the desire length is obtained, the user presses together the loops and hooks sections


62


and


64


for securing the desired length of the adjustable strap


58


. Once a such length is set, the user simply attaches the loop


60


to the hook


54


and no further adjustment is required for subsequent uses. If another user wears the pad


10


, or if the size of the legs of the same user grows, the length of the strap


58


may be adjusted again by doing the same operation.




With references to

FIGS. 2 and 3

, the first and second rigid shin shields


16


and


24


comprise longitudinal apertures


28


and


30


for allowing passage of a strap


38


. Moreover, these rigid shin shields


16


and


24


comprise overlapping surfaces


33


and


35


capable of preventing movement between the upper and lower portions


12


and


22


at a contacting area when the belt


32


is secured in place. More particularly, these overlapping surfaces


33


and


35


comprise respective contacting portions


34


and


36


made of rubber having a friction coefficient which is sufficient for preventing movement between the upper and lower portions


12


and


22


when the belt


32


is secured in place. As seen on

FIG. 6

, a contacting area C is defined when these contacting portions


34


and


36


are press together by the action of the belt


32


.





FIG. 7

illustrates a variant wherein the overlapping surface


33


comprises a contacting portion


134


having a loops section and the overlapping surface


35


comprises a contacting portion


136


having a hooks section. Again, these contacting portions


134


and


136


are capable of preventing movement between the upper and lower portions


12


and


22


when the belt


32


is in place.





FIG. 8

illustrates a second variant wherein the overlapping surfaces


33


and


35


comprise respectively contacting portions


234


and


236


having toothed sections. The shape of the teeth may allow movement of the upper portion


12


relative to the lower portion


22


while also allowing mechanical engagement between these upper and lower portions


12


and


22


, and preventing movement between these portions


12


and


22


when the belt


32


is in place.

FIGS. 9 and 10

illustrate a third and fourth variant respectively. In

FIG. 9

, the shape of the teeth of contacting portions


334


and


336


may allow an easier movement of the upper and lower portions


12


and


22


relative to each other when adjusting the length of the pad


10


. In

FIG. 10

, the shape of teeth of contacting portions


434


and


436


may allow a better mechanical engagement between the upper and lower portions


12


and


22


. Again, these contacting portions


334


and


336


, and


434


and


436


, are capable of preventing movement between the upper and lower portions


12


and


22


when the belt


32


is in place.




With references to

FIGS. 11

to


13


, the belt


32


comprises a strap


38


having at one extremity a ring


40


, and at the other extremity, a loops section


42


which can be joined with a hooks section


44


. The strap assembly


32


also comprises a strap frame


46


having two longitudinal apertures


48


allowing passage of the nylon strap


38


. As seen on

FIG. 13

, the strap frame


46


has a curvature that substantially follows the curvature of the rigid shin shields


16


and


24


.




In use, the user thus moves the upper portion


12


relative to the lower portion


22


until he has obtained the desirable length of the pad


10


. Note that a length indicator


50


applied on the lower portion


22


will give to the user the length of the pad by reading through the hole


52


. Once the desirable length is obtained, the user then pulls the extremity of the strap


38


and presses together the loops and hooks section


42


and


44


. Hence, the upper and lower portions


12


and


22


are secured together since no movement is possible due to the joining action between the contacting portions of the overlapping surfaces


33


and


35


at the contacting area C.




It is understood that the knee, first and second shields may have a configuration, and may be made of a material which provides sufficient protection while also offering sufficient comfort in order to avoid use of padding liners. It is also understood that the first portion may only comprise a knee shield while the second portion may comprise a longer shin shield.
