Abstract
A kind of structure of table tennis bat and the design of shape make the performance of table tennis bat, can be controlled from make.Produce the high-quality table tennis bat according to desired properties.The data that the present invention proposes some kinds of concrete base plates and glue face and cooperatively interacts are to instructing the practical function that is manufactured with of high-quality table tennis bat.
Description
The invention belongs to the racket that ball game is used.
The performance of table tennis bat is very big to the influence of sportsman's technology performance.The sportsman requires racket neither too hard, nor too soft in play, crosses and softly then to send out chaff, to go out ball speed slow, really up to the markly then sends out reality, bat is not caught.Speed influences attack slowly, and not catching, then ball is out of control.For satisfying athletic requirement, the enterprise that makes table tennis bat is a striving direction to make not soft not hard racket all.But up to the present racket performance and corresponding the manufacturing are required to lack scientific theory research, on racket is made, have blindness; For example in order to improve the performance of base plate, the material that only lays stress on base plate is improved and to be thought that making the high-quality plate will use good material, in being to use senior linden, paulownia wood, even use expensive carbon materials, the understanding of clapping shape is also generally rested on the level of appearance looks elegant, and regulation does not influence the dimensional requirement of performance.About to the structure of base plate, sponge and base plate cooperate and the bat type does not have report as yet to the research of the combined influence of racket performance.The decisive factor of racket performance is one of material not only.Only do not improve material owing to recognize the factors and the correlation thereof that influence base plate performance, the quality of base plate performance still is in a kind of irregular governed state.In fact adopt in the racket of high-quality timber making, quality percentage also is no more than 50 percent.Because irregular following, the high-quality product in the every batch of product still needs select by on probation one by one, in a collection of sometimes product even can not find out a racket with high-quality product performance.The previous outstanding paddler of order often choose one have to racket be considered as jewellery because it is too rare really.At present in table tennis bat is produced, can grasp rule, sure the manufacturing taken the post as the high-quality racket with different soft and hard performance that the sportsman selects for use, is still the desired thing of manufacturer and sportsman.
The objective of the invention is under the situation of using common wood or other wood materials, from the structure of table tennis bat with have the high-quality product properties data, the uniformity of assurance product specification and performance in shape the racket of sening as an envoy to.
Content of the present invention is four kinds of the shape structures that the factor that will influence the table tennis bat performance is divided into the elasticity of sheet material, board structure sponge face and thickness and racket, is deciding factor with the board structure under the situation of sheet material unanimity wherein.Calculate and the measured data proposition according to theory, adopting soft softwood of little, the no oiliness of proportion, quality and little, the no oiliness of proportion, line seam greatly and uniform hard wood, during for example linden, white poplar, water willow, sal, pine or other are wooden or wood-fibred sheet material makes that base plate uses three layers or five layers of glued board, lumber grain should be one, 35 layer and be longitudinal grin, promptly consistent direction with bat, two, four layers is band, promptly vertical direction with bat, the gross thickness of three layers or five layers is 6.5～7.5mm, and the interlayer adhesive is the plasticity adhesive of no solid packing.The soft or hard of the performance of the longitudinal and transverse line lumber thickness ratio decision base plate in the base arrangement.The hardness of sponge coverlay can be measured by durometer.What claim 50 ℃ of rubber hardnesses among the design be the m type, promptly soft sponge, 51 ℃ be the n type, i.e. sponge firmly, with on base plate cooperates except that m, n type sponge, can also be with 48～49 ℃ common positive glue sponge.Can produce racket by the soft durometer specification of determining according to the different soft and hard degree of base plate and soft or hard sponge adapted.Bat type of the present invention has designed pen-hold grip and shake-hands grip by the play requirement, has designed square straight plate according to athletic needs in addition.Three kinds of bat types of the present invention's design, its type shape, size are to propose from the angle that satisfies the mechanics requirement.The corresponding to high-quality table tennis bat of first requirement performance can be made and give to material-structure that provides according to the present invention and bat type.
Characteristics of the present invention are under the situation of the timber that adopts identical material or timber-work and sponge, glue face, and by to the various structure Design of table tennis bat, the performance of control racket makes the quality percentage of table tennis bat product reach desirable degree.Another characteristics of the present invention are to use the timber of common material or timber-work and sponge, glue face can produce all kinds of table tennis bats with high-quality product performance.
The present invention is as shown in table 1 about an embodiment of base arrangement design: softwood is S, and hard wood is H.
The bottom plate of 1～4 structure belongs to hard plate in the table 1, and the bottom plate of 5～8 structures belongs to soft board.Wherein every group soft-hard property basically identical in 1 and 3,2 and 4,5 and 7, the 6 and 8 four pair of combination only is to have any different on the flaggy.By performance arrange by hard be (1 and 3) → (2 and 4) to soft order; (5 and 7) → (6 and 8) are divided into fourth gear.
When being the listed sheet material adapted of table 1 sponge, it is 2.2 that soft m type sponge is made thickness, and it is two kinds of 1.9mm and 1.7mm that two kinds of 2mm and 2.0mm, the n type sponge of hard make thickness.The specification of four kinds of sponges is m2.2, m2.0, n1.9, n1.7.Can be by four kinds of sponges of the corresponding adapted of principle and four groups of sheet materials soft and hard collocation, concrete combo is as follows:
A:1(SHS-7.4) and 3(SHHHS-7.4) join m2.2.
B:2(SHS-7.2) and 4(SHSHS-7.4) join m2.0.
C:5(SSS-7.2) and 7(SSSSS-7.4) join n1.9.
D:6(SSS-7.0) and 8(SSSSS-7.0) join n1.7.
Base plate and sponge overall performance that mode is closed in A, B, C, D four assembly are: A is a hard plate, and B is hard plate slightly, and C is a soft board, and D is soft board slightly.
Can intersect matched combined in addition, for example:
A
1: 1 and 3 join m2.0
B
1: 2 and 4 join m2.2
C
1: 5 and 7 join n1.7
D
1: 6 and 8 join n1.9
On this, under eight kinds of situations, all can control soft, the rigid energy of racket on demand.
The present invention is as shown in table 2 about another embodiment of base arrangement design, and present embodiment uses the layer interlayer in cork dust plate R or the wood-fiber board V substituting for plywood; In practicality, has best serviceability.
Linden can substitute with linden poplar, white poplar, willow in the said structure.
The listed various base plate of table 2 all can cooperate with n type sponge, can be used as general senior match with clapping.Cooperating with n1.9 is soft bat, cooperates with n1.7 to be soft slightly bat.
Structure for sponge, an alternative embodiment of the invention is that the flexible sponge of difference is made compound sponge, for example adopt the anti-glue sponge of n type of 51 ℃ of the common positive glue sponge of 48～49 ℃ of hardness and hardness compound, in gross thickness is under the 2.2+0.1mm situation, and the thickness assign group of two kinds of sponges is combined into: n type sponge can be 0.6,0.7,0.8,0.9,1.0mm, surplus thick be common positive glue sponge.This sponge can the above-mentioned various structures of adapted base plate.Especially the base plate performance with folder R layer or V layer in the adapted table 2 is the best.
The shaped design of racket is as shown in drawings:
