Abstract

Tennis, table tennis and badminton are basically sports for hitting balls by holding a racket with a single hand, which is very unfavorable for the balanced development of the body. In order to make up for the deficiency of one-handed strength, tennis players and badminton players sometimes use both hands to hold a bat to complete a batting action, and table tennis balls often cannot use both hands to hold a bat during batting due to physical limitations. The invention provides a power assisting device which can enable a non-holding hand to participate in the process of batting and force exerting, and can give full play to the strength of two arms without influencing the flexibility of whole body batting. The arm-linking power-assisted rod for holding the racket balls is in a rod shape, is fixed on the holding arm of a user through the upper small arm sleeve, the wrist sleeve and the like, and the other end of the arm-linking power-assisted rod is grasped by a non-holding hand which can also participate in exerting force during batting.

Description

Arm-linking booster rod for holding racket

The invention relates to a double-arm power assisting device for holding a racket ball, belonging to sports equipment.

Since the hands holding the bat will affect the body flexibility, tennis, table tennis and badminton are basically a sport that one hand holds the bat to hit the ball. In the process of hitting a kickback ball, tennis players and badminton players occasionally hold a racket with both hands to increase hitting energy, and in the process of hitting a kickback ball, tennis players sometimes use both hands, and badminton players are hardly seen. Table tennis is usually hit with two hands rarely.

The two-handed practice of hitting a ball is limited by physical characteristics, and it is always inconvenient to play the ball, so that the increase of the hitting power is greatly limited. Because the racket handle is longer, and the tennis ball and the badminton ball are heavier, the effect of increasing the hitting force can be achieved by hitting the ball with two hands, but the effect is not always consistent with that of hitting the ball with one hand. The handle of the table tennis bat is short, so that the action is not flexible when the table tennis bat is struck by two hands, and the swinging speed is influenced, so that almost no people use two hands to play table tennis.

The invention provides a batting booster rod capable of being connected with two arms, which can effectively play the advantage of batting and increasing strength by holding the batting with two hands and overcome the adverse factors influencing the body coordination caused by holding the batting with two hands.

The object of the invention is thus achieved; the booster connection between two hands is established by a rod-shaped object with an arm liner sleeve and an elastic energy element, and the hitting force and acceleration are improved by the cooperation of the early force of the non-holding arm and the energy storage and release of the elastic energy element during hitting.

The single-hand batting is very unfavorable for health, the batting hand of a professional player obviously makes a circle thicker than the other arm, and the double-arm booster rod can overcome the defect. For children learning to play, because the hitting power is limited by physical strength, the children cannot fully realize the significance of the power on the returning quality, and after the arm-linked power-assisted rod is arranged, the process of practicing hitting can be accelerated, and meanwhile, the balanced development of the body can be ensured. The arm-linked power-assisted rod can increase more than 50% of hitting power, and can accelerate the hitting process by using the elastic element, thereby having great significance for improving the rotation and speed after hitting

Drawings

FIG. 1 is a schematic structural view of a table tennis type holding racket ball connecting arm batting booster rod.

FIG. 2 is a schematic structural view of an arm-linked ball-striking power-assisted lever for tennis-type holding racket balls.

Referring to the attached drawings, the double-arm ball hitting power-assisted rod for the table tennis comprises a rod body 1, a rod head 2, a small arm sleeve 3 and a non-handle grasping handle 4. The rod body is of a main body structure and is in a hollow tubular shape, one end of a neck piece 5 is hinged to the rod head through a universal shaft 6, the other end of the neck piece is inserted into the hollow tube of the rod body and can slide in the tube for a certain distance and can rotate without limitation, an elastic spring 7 is arranged between the two ends of the neck piece and the hollow tube, and two elastic springs, one elastic spring and one tension spring, can be additionally arranged at the same time. The part of the club head corresponding to the small arm is in a crescent shape 8, two tips of the club head are connected with a small arm sleeve made of semi-rigid material, the small arm sleeve is sleeved on the small arm when in use, a limit cable 9 is connected with a large arm sleeve 10 sleeved above an elbow joint, a limit cable 11 is connected with a wrist sleeve 12 sleeved on a wrist, and then the whole club head can be fixed on the small arm by sleeving the cable bend between fingers through the matching of the two sets. In order to facilitate the recovery of gripping and force after the non-holding hands serve, the surface of the handle is in a fluctuant shape matched with the hand shape, and the top end of the handle is provided with an anti-falling wrist sleeve 13. The universal shaft between the club head and the neck piece and the relative rotation and sliding between the club body and the neck piece can reduce the uncomfortable feeling after the two arms are connected, and simultaneously improve the coordination of batting by forehands and forehands. The spring can store and release the actuation energy of the non-holding hand when the holding hand carries out counterattack on the ball, thereby improving the energy conversion efficiency. In order to ensure that the energy storage and release processes are realized when the player hits the ball by the forehand and improve the coordination of the two arms when the player exerts force, the small arm sleeve can also be made of a strip-shaped elastic band, in order to facilitate the relative rotary sliding of the strip-shaped elastic band on the surface of the small arm part, a gasket 14 made of semi-rigid material can be arranged on the inner side of the small arm sleeve, the gasket can also be an annular sliding layer, the gasket and the small arm sleeve on the outer ring form a structure similar to a bearing, and thus the rod head is hinged with the rod body by a one-way shaft perpendicular to the rod body of the racket, and the universal function is also realized. To facilitate adjustment of the cuff size, an adjustment knob 15 or the like may be provided on the head.

Referring to the attached figure 2, the tennis badminton holding racket connecting arm striking booster rod consists of a rod body 1, a rod head 2, a racket handle cap 16 and a gripping handle 4. Considering that the shaft of tennis racket and badminton racket is longer, it is unnecessary to consider the acceleration action of the shaft, so the rod head of the booster rod is directly fixed on the racket handle through the handle cap, the latter is in the shape of hollow cap, the hollow part of the inner gasket 17 is in the same shape with the handle head of the racket, and can be directly sleeved on the racket handle, and then is fixed on the racket handle through the handle wrist sleeve 18 connected with the racket handle through the limiting cable 11. One end of a neck piece 5 is hinged on the rod head through a universal shaft 6, the other end of the neck piece is inserted into the hollow tube of the rod body and can slide for a certain distance in the tube and can rotate without limit, and a spring 7 is arranged between the two ends. The handle which is not grasped by the hand can be directly fixed on the rod body, or can be hinged on the rod body by a shaft 19 which is vertical to the rod body, and the handle can also be a D-shaped handle 20 or a fixed handle which is coaxial with the rod body.

In specific implementation, aiming at the characteristics of the length of the racket handle, the racket handle can be flexibly intersected in design, for example, a T-shaped or D-shaped handle can be adopted by the table tennis racket, a racket handle cap can also be used on the table tennis racket, a universal shaft can also be replaced by a one-way shaft, the racket handle can also be connected with a small arm sleeve by a limiting cable, and the small arm sleeve can also be directly sleeved at a position close to a wrist. The simple structure of the whole club body and club head can be considered, in order to facilitate the flexible rotation of the whole club body relative to the small arm, the width of the club head arm attaching surface is smaller, and two connecting points of the connecting belt-shaped rubber band small arm sleeve are also close to the arm attaching surface of the club head as much as possible. The racket handle is also provided with a matching design such as a limit rope or a handle sleeve fixing point, and the tension spring in the rod body can be replaced by a strip-shaped rubber band.
