Abstract

A battledore with variable weight is composed of a special balance weight connection throat (3), a special balance weight frame (2), a whole rod (4) of a special balance weight racket rod, a rod section (6) of the special balance weight racket rod, a rod end (7) of a balance weight racket handle, a tail end (10) of the balance weight racket handle, a barycenter adjusting component (13), fixed parts and a standard battledore (1). For the standard battledore (1), the gradual increase in weight and the adjustment of the center of gravity can be achieved.

Description

Badminton racket with variable weight

The invention relates to a badminton racket with variable weight, in particular, a badminton racket with a special weight component and a standard badminton racket, which is fastened by magnetic components, can realize progressive weight gain training, and lightly loaded badminton. Shoot, belongs to the field of sports equipment.

Background technique

The current badminton training uses racquets of immutable weight. The difference between the training and the hand-feeling feels and the actual application period, the sports injury occurs, and the weight-bearing training cannot achieve gradual weight gain.

The invention can realize a gradual weight gain training of the racquet, the relevant joint tissue is gradually adapted, the wrist joint damage is reduced, and the balance of the tempo can be adjusted. Through such racquet training, the joint damage is less, and the swing strength is increased in the light loading competition. And smothering. Summary of the invention

A badminton racket with variable weight, consisting of a counterweight connection throat, a frame, a lever, a handle, a center of gravity adjustment and its fastening device, and a standard badminton racket for progressive weight gain and center of gravity adjustment.

The invention has the following features:

1. The weight connection throat is a magnet group, and the frame and the lever of the counterweight can be connected.

2. The weight frame is lg-10g film series, 10g-50g grade elastic fiber sleeve series, 50g-100g grade perforated belt series, 100g grade strip series.

3. The counterweight lever is an elastic whole series and a rod series.

4. The weight handle is a magnet body, and the shell is equipped with a ferromagnetic adjustment member.

Figure 1 is a schematic view showing the overall structure of a badminton racket;

Figure 2 is a schematic diagram of the connection of the weight frame ring, the connection throat and the lever;

Figure 3 is a schematic view showing the structure of the center of gravity adjustment member.

Figure 1 illustrates the following:

Standard badminton racket 1, counterweight belt loop 2, counterweight connection throat 3, counterweight stick lever 4, standard stick 5, counterweight lever section 6, counterweight grip lever end 7, handle The ferromagnetic adjustment member 8, the standard handle 9, the counterweight handle end 10, the handle weight magnet 11, the magnetic weight grip handle 12, and the center of gravity adjustment member 13.

Figure 2 illustrates the following:

The film series of the weight belt ring 2 is single-sided adhesive self-adhesive fixing; the elastic fiber sleeve series is double-sided adhesive bonding elastic rubber fixing; The perforated belt series and the belt series are groove shapes, the grooves are stuck on the outer periphery of the standard head, and the two ends are fixed with the magnetic connection pins 31 by the connecting throat.

The weight connection throat 3 is magnetized by the component 32, and the symmetric clamping clamp is connected at the connection position of the head and the beater. The head end is fixed by a ferromagnetic tweezers on the joint surface of the joint, and the ferromagnetic opening is used at the end of the rod. The ring or counterweight stick set is fixed; the counterweight lever 4 and the counterweight lever section 6 are elastic open tubes, and the opening curvature is greater than 60° less than 90°. When installing, the opening is aligned with the stick. In.

Figure 3 illustrates the following:

The center of gravity adjustment member 13 is an elastic card member 132 similar to the outer contour of the head of the standard racquet, and is clamped to the frame of the head by the opening of the clip 133 at both ends, and the handle of the clip is removed. When the center of gravity adjustment member needs to be removed, The center of gravity adjusting member opening side groove 131 is inserted into the elastic clip handle 133, and the arching end of the elastic card member 132 is used as a fulcrum to open the nip end, which can be easily disassembled. Specific form

material selection:

Counterweight hole belt ring 2, the grooved belt is pressed by a metal material such as aluminum, copper or iron which is bendable.

The counterweight connection throat 3 is processed by ferromagnetic material into a casting magnet.

The counterweight lever 4 and the counterweight lever section 6 are made of spring steel strips and processed into open tubes.

The counterweight grip end 7 and the counterweight end 10 are formed of spring steel strips, and the opening is similar to the full length of the counterweight.

Handle ferromagnetic adjustment member 8, handle weight magnet 11, magnetic weight handle tying block 12 and center of gravity adjustment member 13, using ferromagnetic material processing molding magnetization.

The combination of negative and heavy shots:

According to the connection throat - the head - the weight of the handle rod end - the weight lever rod - the weight of the handle end - the handle weight magnet - the weight of the handle to block the way to carry out the weight, by adjusting the center of gravity adjustment - Counterweight adjustment - adjust the weight lever section - the handle weight magnet adjusts the weight and center of gravity of the weight shot.

The way the weight changes:

By changing the series or type of breeding parts, the weight is gradually increased, and the weight is selected according to the habits and load-bearing ability of the user and the load capacity of the racket.

The way the center of gravity is adjusted;

According to the user's needs and training requirements, the center of gravity is adjusted by increasing or decreasing the center of gravity adjustment and weight adjustment, increasing or decreasing the weight of the handle, or adjusting the weight of the lever.

The end of the counterweight grip lever 7 is provided with an open slot, and the opening size is the same as that of the counterweight gripper lever, and the opening is aligned with the lever and pushed into the rack. Returning to the end of the standard grip 9, after inserting the counterweight lever, push the counterweight lever closer to the end of the grip; the handle ferromagnetic adjustment member 8 is embedded along the open slot (the magnetic adjustment member is of different sizes) The block or granule), the end of the counterweight handle 10 is a sleeve similar to the standard handle 9 and longer than the standard handle, the handle weight magnet 11 is a magnet piece similar to the standard handle, the weight handle shank seal The plug 12 is a barrel-type side magnet, and the outer contour of the plug is smaller than the outer contour of the end 10 of the weight grip, and the outer diameter of the inner table is embedded in the inner contour of the end of the weight grip.

According to the user's habits and play of the racket center, the center of gravity adjustment member 13 adjusts the number evenly according to the balance requirement.
