Description

Table tennis bat

Technical field

The present invention relates to a kind of table tennis bat.

Background technology

Known table tennis bat is made up of striking plate and racket handle.Racket handle is made of the extension of striking plate and non-disconnectable the sleeve that is contained in above it by general mode.Table tennis bat must under any circumstance satisfy striking plate and keep the reliable requirement that is connected mutually with racket handle.Carried out the experiment of standard, the bat of will batting we can say to a certain extent by extension and is combined in the racket handle that sleeve is loaded onto on the two sides respectively non-disconnectablely in this case, thereby forms racket handle jointly for this reason.Consequently obtain the firm and reliable table tennis bat of a kind of height.

What can not ignore certainly is that racket handle and striking plate are rigidly connected in fact mutually in known table tennis bat.Doing the consequence of bringing like this is, the vibration of striking plate is passed to the racer on hand by racket handle when match.Yet this may influence the racer's " feel of the ball ".Especially when height batting frequency, may destroy racer's the degree of accuracy and respond thus.

Summary of the invention

Can adopt the present invention in this case.The objective of the invention is, table tennis bat is done improvement as described below, thereby get rid of above-mentioned disturbing factor.

Can reach this purpose like this by first suggestion of the present invention, even racket handle has a centre bore along its longitudinal axis, centre bore extends to the racket handle forward region from the rear end of racket handle always, in this centre bore, insert with one heart a diameter than its little pipe as fuse and be fixed in the racket handle forward region, and the annular gap that forms between centre bore and pipe is sealed with a flexible sealing ring in the racket handle rear end.

As can be seen, in known structure, also should keep according to this striking plate, it extension and be contained in sleeve on the extension, certainly this only limits to the forward region at racket handle, and is broken into segmentation by a centre bore along this entity longitudinal axis in the remainder of racket handle.Thereby cause the less rigidity or the activity of being more convenient for.This activity on purpose by elastomeric material by clap from batting or the racket handle forward region be in control damping.

Another kind of scheme is, racket handle is divided into the anterior and racket handle rear portion of racket handle again, there is the additional section of the handle that is contained in the striking plate two sides racket handle front portion, the rear portion comprises remaining handle, be fixed in the racket handle front portion along pipe of racket handle longitudinal axis, there is the vertical hole of a diameter greater than pipe at the racket handle rear portion, the annular gap that forms between vertical hole at pipe and racket handle rear portion is all sealed with flexible sealing ring at the head and tail at racket handle rear portion, and, be provided with separate layer in transition region with compressible and coilable material system from the racket handle front portion to the racket handle rear portion.Adopt this form of implementation not only can be, and in addition can also damping reverse by the bending of special degree damping racket handle.

The advantageously material manufacturing of effective a kind of bending resistance is as aluminium, titanium, carbon fiber or carbon fibre fabric etc.

The sealing ring of being advised not only can be used to damping, but also is used for this table tennis bat is formed a whole, and clings as long as this sealing ring can be pressed in the annular gap or therein securely.If sealing ring be designed to multilayer with different material formation, then sealing ring is particularly suitable for satisfying different requirements.At first consider rubber and/or plastics as material.Also can select other materials for separate layer, as leather, artificial leather or cork.

Cancelled any being rigidly connected between the anterior and remainder (rear portion) at racket handle in this another kind of scheme, whether to contain the original extension of striking plate unimportant concerning it for the remainder of racket handle in this case.Exactly, that racket handle part with illustrated geometry can be designed as one from the beginning, and calling by name, to talk about be to make with a whole block material.

Description of drawings

Below by two preferred embodiments and accompanying drawings other details of the present invention and advantage.In the accompanying drawing:

Fig. 1 is by table tennis bat vertical view of the present invention;

Fig. 2 table tennis bat shown in Figure 1 is along the profile of II-II line;

Fig. 3 table tennis bat shown in Figure 1 is along the profile of III-III line;

Fig. 4 table tennis bat shown in Figure 1 is along the profile of IV-IV line; And

Fig. 5 is by the another kind of form of implementation of table tennis bat of the present invention view as shown in Figure 4.

The specific embodiment

Press Fig. 1 to 4, table tennis bat 1 is made up of striking plate 2 and racket handle 3.The latter is divided into the anterior 3a of racket handle and racket handle rear portion or remainder 3b.The anterior 3a of racket handle still constitutes by traditional mode, that is is made of the extension 4 of striking plate 2, on its two sides sleeve is installed non-disconnectablely, but here sleeve at first can be thought the additional section 5 of racket handle.Racket handle remainder 3b is same consistent with traditional racket handle on its contour shape, certainly it no longer needs to be designed to (the comprising striking plate extension and the sleeve that is contained in above it) of multilayer, as long as from outward appearance or angle of aesthetics, wish that anterior 3a of racket handle and racket handle rear portion 3b seem to be still an integral body.But on function, then no longer be equal to traditional table tennis bat on the contrary.

As shown in drawings, in the zone of the anterior 3a of racket handle, firmly fixed an aluminum tube 6 along racket handle 3 longitudinal axis, it is until centre bore (vertically hole) extension of diameter greater than pipe 6 passed in the rear end (to tail end) of racket handle rear portion 3b.The annular gap 8 that between constitutes, at the head and tail place of racket handle rear portion 3b, all the elastic sealing ring 9 by a rubber system seals, and does so also to help anterior 3a of racket handle and racket handle rear portion 3b to integrate.In addition, also establish the plastic separate layer 10 of a foaming to the transition region of racket handle rear portion 3b from the anterior 3a of racket handle.

Illustrated table tennis bat 1 provides a kind of table tennis bat of comfortable, even this racket is in still stablizing under the situation of height batting frequency and grasping hand the racer reliably.Owing to racket handle 3 separated into two parts and this two racket handle part 3a, 3b are connected to each other, thereby obtain a kind of tangible impact damping.May relate to the various striking plates loads that involve racket handle here, as crooked, reverse or both have both at the same time simultaneously.

A kind of as seen from Figure 5 form of implementation of simplifying by contrast.According to this, racket handle 3 ' still be designed to integral body, but vertical hole 7 is passed racket handle from the end of racket handle rear area 3b ' and is extended to its top.7 inside still have one (less) pipe 6 in the hole, and it is securely fixed in the forward region 3a ' of racket handle.In the end of racket handle rear area 3b ', annular gap 8 usefulness sealing rings, 9 sealings.The latter still is used for damping and can changes its structure and material, that is is complementary with the match character of stipulating.
