Description

The table tennis shake-hands grip

Technical field

The present invention relates to a kind of sports goods, refers to a kind of table tennis shake-hands grip particularly.

Background technology

Table tennis bat can be divided into two kinds of pen-hold grip and shake-hands grips, and the handle of pen-hold grip is shorter, and the handle of shake-hands grip is longer.Table tennis bat is made up of glue face, base plate, handle.The general grip of shake-hands grip table tennis player is that middle finger, the third finger and little finger of toe are held handle naturally now.Thumb gently is attached to the middle finger next door in the front of racket, forefinger stretches naturally, tiltedly is put in the back side of racket, makes the handle afterbody be positioned at the palm of the hand outside.The characteristics of shake-hands grip grip are that froehand-backhand attacking driving strength is big, and hold changes for a short time during the tapping ball, and backhanding attack has an effect easily also is convenient to the arcing circle; But froehand-backhand replaces square stance, needs conversion batting face, and it is big to attack tiltedly, regulate during straight line the amplitude of clapping shape.To be handle and base plate center axis line need curve wrist and run into wrist to prevent the handle afterbody for the coaxial configuration froehand-backhand replaces square stance the structure of existing table tennis bat.Existing on the other hand handle structure is the position, main position that slim-lined construction handle when holding bat can not contact the palm of the hand, and the stability of holding bat is slightly poor.

China's utility model patent patent No. 02235998.2 discloses a kind of askew handle table tennis bat of changing hands, and comprises striking plate and handle, and wide of described handle reverses certain angle with the striking plate face.Be equivalent to handle and plate face not at grade; Though its also have open handle and plate face at grade curve structure, it curves to handle is whole and curves with the face axis, causes the handle top to be positioned at face one side and not coaxial with the face central axis; Hold the whole center of gravity in bat back and be positioned at face one side; Cause that like this racket rocks when playing ball, what influence was batted stablizes, and does not propose to improve the stable technical scheme of holding bat of batting.

Summary of the invention

The invention provides and a kind ofly hold bat that the conversion of comfortable, froehand-backhand is fast, the table tennis shake-hands grip of good stability.

A kind of table tennis shake-hands grip; The handle that comprises clappers and clappers afterbody; Clappers plate face edge is connected with the handle circular arc, and holding bat with the right hand is benchmark, and the handle left side is provided with along the axial interior concave arc of clappers; Described handle right side is a turning point with clappers plate face edge circular arc tie point, and the handle level curves with handle right side bottom apex and clappers central axes.This kind structure is the further inventive improvements on the utility model patent patent No. 200920124430.9 bases of the applicant's application, has mainly further improved the stability and the comfortableness of holding bat and has improved froehand-backhand conversion speed and increasing attacking driving strength.Specifically the handle left side is along the axially interior concave arc of clappers; Middle finger, the third finger, little finger of toe can be carried on the interior concave arc in edge when holding bat; Abutment indent circular arc place is higher than the tiger position of hand in the formation, and optimum structure is that middle abutment indent circular arc place is higher than on the present table tennis bat of tiger position this kind of 1cm structure of hand for the handle turning point is 3.5cm with the vertical range that the handle top belongs to the plane.The vertical range on indent circular arc summit and plane, place, handle top is 0.5cm.When general froehand-backhand is changed lifting the ball; Need to clap head down puts backward; The traditional structure middle finger often withstands racket to be difficult to the bat head is put down; Be difficult to form the form of holding bat that middle finger is higher than tiger, and this structure keeps middle finger to be higher than the form of holding bat of tiger always, and good result is played in racket froehand-backhand conversion speed-raising.The handle right side is a turning point with clappers plate face edge circular arc tie point on the said structure basis; The handle level curves with handle right side bottom apex and clappers central axes, is equivalent to the handle afterbody is moved outward, like this when holding bat; Can make and clap head reduction height 10cm naturally; Do sth. in advance swinging the bat the time of 10cm when making lifting the ball, avoided in the traditional structure handle and the same axis of face caused when froehand-backhand is changed simultaneously, its handle afterbody one side is run into wrist easily.The player at least also will just can avoid running into wrist around some circles even skillfully rattle at present.Though solved this technical barrier for the question patent of running into wrist number 02235998.2 disclosed a kind of askew handle table tennis bat of changing hands; The central axis that back middle finger, the third finger, little finger of toe, thumb and palm form but it is held bat is coaxial with handle; Do not cause the stability of holding bat not enough with the face axis coaxle; And the present invention's back middle finger of holding bat contacts with interior concave arc, and tiger contacts with the circular arc of face and makes palm axis and the face coaxial stabilization raising of holding bat.

Bottom apex is a circular arc to described handle right edge turning point to the right side; The handle left side of corresponding handle right circles arc is a linear; The curved shape that the structure of circular arc has been pressed close to the palm of the hand when holding bat has improved the comfortableness of holding bat, and the linear of the opposing party's handle left side has also been pressed close to the shape that middle finger, the third finger, little finger of toe hold bat and further improved comfortableness.

It is to become big elliptical table structure gradually to the handle bottom that described handle begins along the handle axis from turning point; Frustum cone structure that this kind is gradually big and the palm hollow rounding platform structure that constitutes of holding bat is coincide; Be equivalent to form a back-off device; The firmness of holding bat is increased, avoided the table tennis player in the batting process, to worry the psychology misgivings that racket is slipped out of the hand fully, strengthened user's striking force.It is to be noted that it quite is a kind of cylindrical sleeve structure that in the past handle and palm held bat, and lacks the fastness of holding bat and slips out of the hand easily.The physical dimension of above-mentioned the best is that the oval major axis of the cross section of described handle bottom surface is 4.4cm; Minor axis is 3.7cm, and the process turning point is a turnover face perpendicular to the cross section of clappers central axis, and its cross sectional shape on handle is oval; Oval major axis is 2.9cm, and minor axis is 2.4cm.This size is big or small being suitable for of holding bat according to the size formation of present user's palm.
