Description
- This application claim priority from the U.S. Provisional Patent Application No. 62/312,045, filed on Mar. 23, 2016, the entire content of which is incorporated herein by reference.
- The presented invention relates generally to portable sports exercising equipment, and particularly to the adjustable and portable all-muscle wrist power exercising rod.
- Wrist power is very impotent in racket games, especially in badminton. Every serious badminton player wishes to have a powerful wrist to perform a sudden and fast power smash. The wrist power of a good badminton player shows off during a smash is actually comes from forearm and fingers. Wrist itself does not have any muscles, it is just a joint that allows hand bending, swinging and rotating. All these wrist movements are controlled by the muscles in the forearm. Fingers provide the last control and power at the striking moment. Thus, to improve wrist power, one need to practice the muscles that control pronation and supination of forearm, flexion, abduction and rotation of wrist, and griping of fingers.
- Commonly used portable wrist power exercising equipment includes wrist roller, grip-ball, hand griper, and forearm flexor griper. Wrist roller mainly exercises wrist flexion, wrist abduction, and griping strength by using a rod to roll up a string with a weight hanging on it. Grip-ball is a ball made of elastic material and is used to improve finger muscles and grip strength by squeeze the ball with one hand at a time. Hand griper is very similar to grip ball but use spring instead of elastic material. Forearm flexor griper, as it named, is used to exercise the forearm flexor. From above brief description, it is concluded that all these equipment are working on finger muscles and forearm flexor but does not particularly workout the muscles that control forearm pronation and supination which is the strongest wrist movement and actually contributes major power for forehand smash, forehand clear, backhand smash and backhand clear than wrist flexion in a badminton game.
- The invented “adjustable and portable all-muscle wrist power exercising rod” abbreviated as wrist power exercising rod.
- The invented wrist power exercising rod provides a complete solution to practice all muscles involved for wrist power. Furthermore, it does not only make the muscles stronger but also enhance the blasting ability of the wrist and forearm. It is also adjustable to meet the requirements of different levels of exercising strength. Obviously, this new exercising equipment does not only benefits badminton players but also many other sports.
- There are two exercising modes for the invented wrist power exercising rod: waving-mode and twisting-mode. In the waving-mode, an exerciser waves the wrist power exercising rod (by holding at the
handle part 300 with one hand at a time) in certain patterns to exercise the muscles for pronation and supination of forearm, flexion, abduction and rotation of wrist. In the twisting-mode, an exerciser use both hands to twisting the twisting-assembly-1 130 (as shown inFIG. 6 ) or the twisting-assembly-2 140 (as shown inFIG. 7 ) forward and backward over and over again to exercise the muscles for finger griping and wrist bending. - In order to understand the features of the invention, a detailed description of the invention may be had by reference to certain embodiments, some of which are illustrated in the accompanying drawings. It is to be noted, however, that the drawings illustrate only certain embodiments of this invention and are therefore not to be considered limiting its scope, for the scope of the invention encompasses other equally effective embodiments. The drawings are not necessarily to scale, emphasis generally being placed upon illustrating the features of certain embodiments of the invention.

FIG. 7.1 shows partial view (a), partial cross-sectional view at initial position (b), and partial cross-sectional view at a 90 degree rotated position (c) of the type II twisting assembly that used in the wrist power exercising rod shown inFIG. 7 . -
FIG. 1 schematically shows an embodiment of invented wrist power exercising rod which is used in the waving-mode. In this embodiment, the wrist power exercising rod comprises a tubeshaped body part 100, adetachable head part 200 attached to one end of thebody part 100, ahandle part 300 attached to another end of thebody part 100, and means of changing the torque of the wrist exercising rod. Eitherhead part 200 or handlepart 300 has option of being detached to load thebody part 100 with heavy filling material such as sand, salt and heavy metal pieces for the purpose of changing the barycenter of the exercising rod thus changing the torque of the wrist power exercising rod during the waving-mode practice.FIG. 2 shows other different options of thehead part 200 and handlepart 300.FIG. 2(a) shows a sealedhead part 201;FIG. 2(b) shows a length adjustable head part 203; andFIG. 2(c) shows an end sealedhandle 301. The weight of the filling material determines the torque of the wrist power exercising rod when the rod is waved in an exercise pattern which is originated from wrist movement and powered by forearm muscles. It is commonly known that the torque is the tendency of a force to rotate an object about an axis or (a point). The value of the torque is the product of the distance from the barycenter of the object to the axis and the weight of the object. When one waves the rod by using the wrist and the forearm movement so that the trajectory of the head of the rod is a double-circular “∞” pattern, the weight material that filled inside the body of the wrist power exercising rod will be pulled to the head end by centrifugal force. Thus the torque of the wrist power exercising rod in wave-mode is roughly the product of the length of the rod and the weight of the loading plus the torque of the wrist power exercising rod without any loading of the filling material. Obviously, this torque can be easily changed by changing the amount of the filling material. -
FIG. 3 schematically shows another embodiment of invented wrist power exercising rod which is used in the waving-mode. In this embodiment, the wrist power exercising rod comprises a tube shapedbody part 101, adetachable head part 200 attached to one end of thebody part 101, ahandle part 300 attached to another end of thebody part 101, a number ofweight discs 210, and anexternal weight piece 400. Thebody part 101 has a screw thread on its surface so that theexternal weight piece 400 can be spirally moved along thebody part 101 thus changes the barycenter of the wrist exercising rod. The means of changing the torque of the wrist exercising rod in this embodiment is thus realized. Theweight discs 210 can be optionally removed or added into thehead part 200 to extend the torque adjusting range. -
FIG. 3.1 shows yet another embodiment similar to the structure as shown inFIG. 3 .

Theelastic tube 132 a, which is connected to the twist-handle-1 132 b and twist-handle-2 132 c, is made of elastic material and is twistable. The spring-1 131 a is placed between thetwist handle cap 132 d and thespring limit section 104 a and the spring-2 131 b is placed between the twist handle-1 132 b and the twisting-torque adjusting section 104 b. There is a screw thread inside the twist-handle-2 132 c, so that the twisting sleeve can spirally rotates on the twisting-torque adjusting section 104 b to press the spring-1 131 a or spring-2 131 b or both of them thus theelastic tube 132 a is pre-stretched. The tightenknob 133 is used to fix the twistingsleeve 132 at a desired position on the twisting-torque adjusting section 104 b. Once the twistingsleeve 132 is fixed at a desired position (which also means that theelastic tube 132 a is pre-stretched by a desired tension), the twist-handle-1 132 b and the twist-handle-2 132 c are rotated by both hands in opposite rotating directions thus the elastic tube 130 a is twisted similar to a towel is twisted to squeeze the water out. Repeatedly twisting theelastic tube 132 a in alternated rotating directions can thus exercise the finger griping and wrist bending. The spring-1 131 a and the spring-2 131 b are helical springs (as shown inFIG. 6.2 ) and may have different or same lengths. When the position of the twistingsleeve 132 is adjusted on the twisting-torque adjusting section 104 b toward the handle, the spring-1 131 a or the spring-2 131 b will be pressed first, then the other spring will be pressed after. The spring-1 131 a and the spring-2 131 b may have different or same spring constants. The spring constant represents the stiffness of a spring. The spring-1 131 a and the spring-2 131 b can be replaced by a single spring also as long as thespring limit section 104 a is eliminated. -
FIG. 7 illustrates another embodiment of wrist power exercising rod which can be used in both waving-mode and twisting-mode. The wrist power exercising rod in this embodiment comprises a twisting-assembly-2 140 attached on a waving-mode wrist power exercising rod with all the structure and the function remain the same as shown inFIG. 5 except the body part 103(inFIG. 5 ) is changed to a body part 105(inFIG. 7 ) which has anadjusting section 105 a built on it. The twisting-assembly-2 140 further comprises a twist handle 140 a, astretcher holder 140 b, astretcher 140 c, astrainer 140 d, and theadjusting section 105 a. Detailed structure of twisting-assembly-2 140 is shown inFIG. 7.1 . The adjustingsection 105 a is a section on thebody part 105; part of this section has screw thread that matches the screw thread in thestrainer 140 d so that the position of thestrainer 140 d can be spirally adjusted on theadjusting section 105 a; the rest part of this section where has no screw thread functions as a twisting handle. One end side of theadjusting section 105 a that near the middle position of the exercising rod has an inclined step (as shown inFIG. 7.1(b) and (c) ) and the twist handle 140 a has an inclined end plane at one end that matches the inclined step of theadjusting section 105 a. When thebody part 105 and the twist handle 140 a are rotated in opposite directions (from the original relaxed position as shown inFIG. 7.1(b) ) by a less than 180 degrees of absolute rotated angle, thestretcher holder 140 b, will be pushed away from thestrainer 140 d due to the opposite movement of the inclined step and the inclined end plane. The maximum push away distance is d/tanθ, where d is dimeter of the twist handle 140 a and θ is the inclined angle (as shown inFIG. 7.1(b) ). As thestretcher holder 140 b is pushed away from thestrainer 140 d, thestretcher 140 c which is connected to thestretcher holder 140 b and thestrainer 140 d is stretched. The stretcher mentioned above is a device that can be stretched like a rubber band or a spring or anything have same function. InFIG. 7.1(c) , the situation of a 90 degrees rotation and thus ½ d/tanθ of the push away is illustrated. The effort needed for this twist and push away is determined by the strength of thestretcher 140 c, the inclined angle(θ), and the preset location of thestrainer 140 d. This effort determines the exercising strength of the twisting mode and is adjustable by setting the location of thestrainer 140 d. - As used herein, a part or function recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural said parts or functions, unless such exclusion is explicitly recited.
