Device to exercise the stick handling for hockey player, stick handler

Abstract

Invention to drive the handling of a hockey stick (the Stick Handling) by strengthening the hand's pronator and supinator muscles in order to improve the control, speed, strength and technique for handling a hockey puck. The exerciser primarily use is to isolate the pronation-supination movement so younger and older users, experts and beginners, professional and amateur are able to develop and identify the most accurate gesture to perform perfectly puck dribbling. The flexion-extension of the elbow is a common mistake among hockey players and can therefore be avoided. Thereafter, when the correct movement is well assimilated, the exerciser can be used to improve the movement quality, speed and/or strength.

Description

Invention of a device aimed the training of the handling of the hockey stick (stick Handling) by strengthening pronator and supinator muscles of the hand, allowing the improvement of the control, the rapidity of execution, the strength and especially the good technique of handling a hockey puck. This device is meant to isolate the movement of the dribble of the puck by the hockey player, to strengthen it and refine it.

The movement of pronation-supination is hardly detectable and measurable by a coach's eye. This movement is short, fast and with high amplitude mainly contributing to the rapidity of the dribble as well as the shot in ice hockey. Usually, the education received the technique or the tool (device for exercise) that will use the hockey players for practising puck dribbling refer to a movement of flexion-extension of the arm which is a non-optimum technique in the practice of the dribble in ice hockey. The movement of flexion-extension is considered in terms of biomechanics as a coarse movement mainly used to generate brute force instead of performing a movement of great precision. Therefore, when a player makes a movement of flexion-extension of the arm in order to perform a dribble, he can hardly control the amplitude of the latter while generating a high speed, a essential quality to perform an efficient dribble. By contrast, a dribble by pronation-supination of the forearm allows to meet these requirements thus getting a dribble of quality well above.

The device is designed mainly to isolates the movement of pronation-supination allowing young and older, gifted or novice, professional or amateur to identify the exact gesture to perform for a puck dribble and refine it. Thus, the movement of flexion- extension of the elbow is avoided, a common mistake among the hockey players. Moreover, once the movement of pronation-supination is well assimilated, it allows the quality improvement of the dribble expressed by the increase of its rapidity of execution, of the force deployed or both simultaneously.

Once the movement is isolated, the device offers a variable resistance which allows targeting certain essential muscles for a dribble and strengthening them. To properly control the amplitude during the movement, a sound device warns the user and allows him to control precisely the degree of pronation-supination necessary to achieve the maximum amplitude according to the human biomechanics. More in details, a supination at 90 degree and a pronation at 85 degree both starting from the zero position respectively describe the maximum amplitude. When each position are reached, an audible as well as a light signal indicate simultaneously the user that the maximum amplitude is reached and immediately inform the exact moment to change the direction of the movement. The total amplitude of movement is 175 degree around a longitudinal axis.

Of course, the device distinguishes itself from other devices who work the flexor and extensor of the wrist which are of different muscles. It is noteworthy to mention that mostly of these muscles do not cross the wrist joint Therefore; they are rarely solicated during movement of flexion-extension of the wrist. However, they are extremely solicited during rotation of the radius on the cubitus since their origins and their inserts are located on these latter. Since they are very short, these latter contribute predominantly to the speed deployed during the dribble.

Few inventors have designed a device working on the techniques to use during a dribble. Moreover, these same techniques did not allow an effective training of a dribble since they do not involve the movement of pronation-supination. In addition, none has combined in a single device nowadays an apparatus used to assimilate the proper technique as well as to strengthen the solicited muscles during the motion. Even now, there is no such device that has a guiding system based on sound and visual warnings on the efficiency of the movement and a system of resistance. (CA 2642520)

Our invention combined all the elements above in an all-in-one device. It allows the user to learn the correct movement of the dribble, to strengthen the solicited muscles to this movement and to refine its accuracy.

The Device is Described in Tree Sections:

• • 1—The upper part is a shaft which is similar to a hockey stick by its shape and its size, adjustable in length to allow the user to adopt the appropriate position depending on its size. The upper part of the patent is showed especially by the drawing (picture 1) with a side and over view.
  • 2—The middle part consists of a cylindrical mechanism, fitted with an adjustable screw as well as a brake system which generates a continuous resistance and uniform in longitudinal torsion of the shaft. This allows provided a resistance during the pronation of the shaft as well for the supination. A device allows the decreasing or increasing of the resistance depending on the strength of the user and the effect sought by the latter. A mechanism consisting of a steel rod passing through bearings is found in the internal part of the cylinder. The rod also passes through a metal wheel weld to the latter. This mechanism therefore facilitates the rotation and provides increased stability to the upper part of the device. Thus, when the shaft of the upper part performs a rotation, the rod follows the movement which drives the wheel by with it. The wheel's motion is affected by the pressure of the brake on the latter. This brake is pressing directly on the wheel and is modulated by a screw outside the cylinder to adjust the pressure on the wheel and thus change the resistance to the movement of rotation. To be found inside of the cylinder, a device allowing emitting an audible signal to two fixed positions in relation to an origin when the rod reaches these two positions (rotation motion in degree compared to an origin). This part has insertion adaptors on the rod that allows assembling the upper and lower parts of the device with the middle one. The special feature of this part allows a rapid movement of rotation left-right while keeping a constant resistance throughout the movement and this even when changing direction of the movement of pronation-supination carried out by the hands. The constancy of the resistance is a key element of the invention and this at any given time of the movement. The middle part of the patent is showed especially by the drawing (picture 2) with an inside view.
  • 3—The lower part contains a mounting element composed of one or several suction nozzles, weighed, permanent mountings bolted or any other serving as a point of support or anchor to the device. It allows, being fixed, that both parts may turn with specific resistance. It also includes a pin that allows immobilising or not the pivot, up\down and left\right to increase the degree of freedom of the movement. In addition, a 15 to 30 centimetres stick which acts as a hockey stick by its shape and its size or a result of the plastic cylinder of the middle part, is there. The lower part of the patent is showed especially by the drawing (picture 3) with a global and inside view.
