HOCKEY STICK

Abstract: A hockey stick (10) includes a blade (12) having forehand and backhand puck striking surfaces (16, 18). The forehand surface (16) is concavely curved throughout substantially the entire length of the blade (12), and the blade (12) is bifurcated in the toe region to provide fore and back toe segments (26, 28) that are independently transversely flexible. The blade (12) may be employed in combination with a curved handle (14), and may have a forehand surface inclined in the forehand direction for relatively greater effective curvature. A cushioning blade toe end cover (36) is also described.

Description: The invention relates to hockey sticks. Hockey sticks currently used by National Hockey League players have a blade that is longitudinally curved from heel to toe, the blade being concavely shaped on the forehand puck striking surface for improved control when receiving, manoeuvering and shooting the puck from the forehand. Cote U.S. Pat. No. 4,570,932 suggested an ice hockey stick having separate forehand and backhand blade portions, each defining puck striking surfaces, and a wedge, e.g., of plastic material, between the blade portions, to provide a curved forehand surface and a straight backhand surface. The present invention has arisen from my work seeking to improve the construction of hockey sticks. According to the present invention, I provide a hockey stick having a handle, and an elongate blade extending from a heel portion at one end of said handle and terminating in a bifurcated toe portion at an end spaced from said heel portion, said blade defining a concavely curved forehand puck striking surface terminating in a fore toe segment and a backhand puck striking surface terminating in a back toe segment; characterised in that said backhand puck striking surface is concavely curved along at least a portion of its length, and in that said fore toe segment and said back toe segment are spaced apart, have an open space between them, define an acute angle between them, and are longer than they are thick so as to allow said toe segments to flex independently for improved puck control on the forehand and on the backhand. In preferred embodiments, the backhand puck striking surface is concavely curved throughout substantially the entire length of the blade; the backhand puck striking surface is concavely curved from a median line along the blade to the toe portion of the blade, preferably the blade further comprising a playing surface engaging edge terminating upon the bifurcated toe segments, the playing surface engaging edge of the back toe segment, when the puck striking surfaces are disposed substantially normal to a playing surface, extending upwardly, out of engagement with the playing surface in a manner to allow the forehand puck striking surface to be inclined for a forehand "roofing" or "lift" shot; the handle curves longitudinally throughout its length, the handle having a backhand surface lying forwardly of a plane generally through the backhand puck striking surface; and the forehand puck striking surface has a toe end and a heel end, and is inclined toward the forehand direction relative to a position in which the heel end of the curve lies generally tangent to a plane of the forehand surface of the handle, whereby the surface has an effective curvature relatively greater than a conventional curved blade of comparable measured curvature. Other features and advantages of the invention will be apparent from the following description of the preferred embodiments. I turn now to the structure and operation of the preferred embodiment, after first friefly describing the drawings, in which: Fig. 1 is a plan view of a prior art hockey stick having a regulation curved blade; Fig. 2 is a perspective view of an embodiment of hockey stick constructed in accordance with the present invention; Fig. 2a is a front elevation of the hockey stick blade of Fig. 2; Fig. 2b is a front elevation of the hockey stick of Fig. 2; Fig. 2c is a front elevation of the hockey stick blade of Fig. 2. in position to make a roofing shot; Fig. 3 is a plan view of the hockey stick blade of Fig. 2; Fig. 4 is a perspective view of the backhand puck striking face of the hockey stick blade of Fig. 2, without the protective sleeve, and Figure 5 is a perspective view of the protective sleeve for the toe of the hockey stick blade; Fig. 6 is a plan view of a conventional hockey stick with an offset blade; and Fig. 7 is a plan view of an embodiment of bifurcated hockey stick in accordance with the present invention with an offset blade. Referring to Fig. 1, there is shown one typical prior art hockey stick 2, having a conventional curved blade 4, the curved forehand puck striking surface 5 lying generally tangent to the plane, P, of the forehand surface 6 of the stick handle 7 at point T, at the heel 8 of the blade, and extending longitudinally in a concave shape to blade toe 9. (For clarity, the blade is shown in a simple profile, without representation of variation of the vertical incline, as would be typical.) In National Hockey League play, the maximum depth of the curve (C M ) of puck striking surface 5 is 0.5 inch; (1.27 cm), resulting in an effective curvature of C E , measured from the plane of surface 6. In Figs. 2 and 2a, there is shown a hockey stick 10 having blade 12 and a handle 14. Blade 12 terminates is a bifurcated toe portion 15 and has a forehand puck striking surface 16 and a backhand puck striking surface 18. The forehand surface 16 is uniformly, gradually curved longitudinally throughout substantially the entire length of the blade from the heel 20 to the toe end 22, the curve producing a shallow concave surface. The backhand surface 18 of the blade is essentially straight between the heel of the blade and median line 24 of the blade, which is located about two-thirds along the length of blade from the heel, in the direction of the toe. From the line 24 forwardly to the toe end 23 of the blade, the backhand surface is gradually and uniformally curved divergently from forehand surface, with approximately the same degree of curvature as the forehand surface. The toe region of the blade is bifurcated into fore toe segment 26 and back toe segment 28. Space 30 separates toe segments 26 and 28, allowing them to flex independently. When the blade is disposed with the surfaces 16, 18 of the blade substantially normal to the playing surface 32, the lower playing surface-engaging edge 34 in the region of the rear toe segment 28 extends at an angle, away from engagement with the playing surface, e.g., the lower edge of the back toe segment 28 at the toe end 23 is about 1/2 inch (1.27 cm) above the lower edge of the fore toe segment 26. Preferably, the toe of the blade is covered by protective sleeve 36. The sleeve is made of a hard, rubber material, about 1/32 to 1/16 inch) (0.079375 to 1.5875 cm) thick. The sleeve is designed to fit snugly over the toe of the blade, and, prior to use, the sleeve 36 may be affixed to the blade, e.g., by wrapping tape around the blade in the area of tabs 38. Referring to Fig. 2b, shaft or handle 14 is gradually and uniformally curved throughout its length generally from the point 40, where the handle is joined to the blade 12, to the upper end. The shaft backhand surface 42 is forward of the backhand puck striking surface 18. The shaft curvature is somewhat exaggerated in degree in Fig. 2 for the sake of clarity of illustration; the top end of the shaft backhand surface 42 is typically offset by about one-half inch (1.27 cm) from the point 40 where shaft curvature begins. The blade illustrated allows for good control and velocity of both forehand and backhand passes and shots. Referring to Fig. 2c, the raised tip of the lower edge 34 in the region of the back toe segment 28 allows the stick handler to rock the toe end of the blade towards the backhand surface while keeping the lower edge of the fore toe segment 26 on the ice 32 in position for a "roofing" or lift shot, which involves getting under the puck with the toe end of the forehand face and lifting the puck off the ice. The shot is the common means by which a goal is scored in the upper corners of the hockey net. Keeping the lower edge of the forehand toe member on the ice allows for good control of the shot. Also, on the forehand, the offsetting of the shaft 14 forwardly of the general plane of the backhand surface of the blade causes the blade to produce greater puck velocity, and the curved shaft enables better stick handling and control when passing or shooting the puck. The space 30 provided between the fore and back toe segments allows the toe members to flex independently of each other. This independent transverse flexibility allows the stick handler to get better velocity and control of a puck that strikes the blade in the toe region, both on the forehand, and on the backhand. The sleeve 36 cushions a blow if the toe of a blade makes contact with another player, and thus helps to protect hockey players from serious injury. Referring to Fig. 6, to provide a greater degree of effective curvature (C E ′) in a conventional hockey blade 2′, without exceeding the limitation of measured curvature (C M ′), the toe end 9′ of the forehand puck striking surface 5′ is angled toward the forehand direction (arrow F) from the heel 8′ of the blade. The resulting effective curvature (C E ′) is greater than the effective curvature (C E ) of the blade of Fig. 1 for improved accuracy and velocity, while the measured curvature (C M ) is unaffected. In the illustrated bifurcated hockey blade in accordance with this invention shown in Fig. 7, the degree of measured curvature (C M ″) of the forehand puck striking surface affects the curvature of the backhand puck striking surface, except in the toe region. As discussed above, the backhand toe also restricts the ability of a player to lift the puck in a roofing shot, particularly with a more severely curved forehand puck striking surface. Referring to Fig. 7, the forehand puck striking surface 16′ of a bifurcated hockey blade 12′ has a measured curvature (C M ″) less than the maximum allowed. e.g., 3/8 inch (0.9525 cm), but the toe end 9″ of surface 16′ is inclined toward the forehand direction (arrow F) from the plane P″ of the handle (or blade shaft) forehand surface 50 to provide a relatively greater effective curvature (C E ″) and better accuracy and velocity. The inclination of the forehand puck striking surface also advantageously affects the backhand puck striking surface for improved stick handling, passing and shooting on the backhand. Various embodiments are feasible. For example, the backhand puck striking surface can be concavely curved throughout substantially the entire length of the blade, or may be concavely curved from a median line along the blade to the toe portion. Moreover, the protective sleeve can be designed to cover the toe region of a conventional hockey stick blade, the resultant hockey stick comprising conventional stick and bifurcated cover comprising an embodiment of hockey stick in accordance with the present invention. The blade portion at shaft 39 and handle portion may be separable, e.g., at line 40, for replacement of either components. It will also be appreciated that sticks and blades may be constructed in accordance with the invention for use in ice hockey or in street hockey, where a ball is substituted for the puck. Terms such as "puck striking surface" and "puck control" are therefore to be taken to include the corresponding expressions such as "ball striking surface" and "ball control".
