Abstract

A kind of racket protector structure, form by the identical relative fit of two halves sheet, half and half comprises flat rectangular, have parallel in fact inner surface and outer surface, a rectangular side is section linearly, and another opposite sides is the waveform curve section with alternate peaks portion and paddy portion, and inner surface is in the peak of waveform side portion, integrally formedly clap the conduit that line wears for racket, with respect to inner surface be angle towards peak portion protuberance direction forward or reverse inclination extend certain-length.Be installed in frame of racket respectively at the two halves sheet, and when being combined into whole protector structure, plural conduit promptly is in turn tilted configuration in the opposite direction.

Description

Racket protector structure

The invention relates to the rocket protector structure.

Known racket protector structure is shown in Fig. 1-4, be at the inner integrally formed inwardly vertically extending single or double plural conduit b of flat surface a, when being attached to the frame of racket outside, conduit promptly inserts and runs through the default through wires hole in outside in the frame, the usefulness of clapping the line threading for racket.

Application was entitled as the patent application of " vibration control structure of racket " for 92229156.X number to the inventor on July 30th, 1992, be in the frame of racket, to be provided with in week along center line in fact to be vertical outstanding spine inwardly, in this spine's appearance soft padded coaming is set, contact with the bat line, giving damping effect to clapping line, thus the patent of getting permission.Cooperate this structure, the threading of clapping line must be from the center in the frame outside, inwardly tilt to be crossing to this spine both sides in turn in the opposite direction, situation perpendicular to the frame cross section is different in fact with known racket strings hole, therefore, the bluff piece of known vertical conduit can't be suitable for, and in fact the bluff piece that conduit tilts in turn in the opposite direction can't utilize the injection mo(u)lding manufacturing.

Purpose of the present invention is to provide a kind of racket protector structure, applicable to clapping the line threading that inwards tilts from the frame outside, and can injection mo(u)lding produce in a large number.

Above-mentioned purpose, be to reach with racket protector structure of the present invention, its protector structure is made up of the identical relative fit of two halves sheet, half and half comprises flat rectangular, have parallel in fact inner surface and outer surface, this rectangular side is section linearly, another opposite sides is the waveform curve section with alternate peaks portion and paddy portion, this inner surface is in the peak of this waveform side portion, integrally formedly clap the conduit that the line threading is used for racket, with respect to this inner surface be angle towards this peak portion protuberance direction forward or reverse inclination extend certain-length.

Racket protector structure of the present invention, when its two halves sheet is installed in frame of racket respectively, and when being combined into whole protector structure, individual other plural conduit promptly is in turn configuration in the opposite direction.

The above-mentioned and other purpose of the present invention, characteristics and advantage can be more clear by following detailed description the in detail with reference to instantiation shown in the accompanying drawing, in the accompanying drawing:

Figure 11 is Figure 10 racket protector structure reverse side perspective view;

Figure 12 is the sectional drawing along Figure 10 XII-XII line.

As shown in Figure 5, racket protector structure of the present invention in two sheet 1,1 ', mutually the same, by resin injection moldings such as polyvinyl chloride, polyamides, form with the relative fit of the mode of reverse symmetry again.Half and half 1 or 1 ' comprise that formation own is flat rectangular, see Fig. 7 for details, have parallel in fact inner surface 2 and outer surface 3, a rectangular side 4 is section linearly, and another opposite sides 5 is undulate curve section then, has peak portion 6 and paddy portion 7.Inner surface 2 is in the peak portion 6 of waveform curve side, integrally formed plural conduit 8(8 ') (is illustrated as five conduits, but do not limit this number), be angle with respect to this inner surface 2 and forward tilt to extend certain-length towards grand portion, approximate the length in the frame of racket outside 9 to inboard 10 in fact, referring to Fig. 8.Two halves bluff piece 1,2 ' run through the default through wires hole of a row of frame inboard 10 respectively, but form a row in 9 in the frame outside, see Fig. 9, only example half and half bluff piece shown in Figure 9 has only three conduits.As seen from Figure 9, racket protector structure of the present invention is not covered in the frame total length, is to cooperate above-mentioned 92229156.X patent application case to use event, and this preceding case is listed reference in this.

Another embodiment of the present invention corresponds to Fig. 5,9 and 6 of first embodiment respectively shown in Figure 10,11 and 12.In comparison, find that easily this second embodiment and first embodiment do not exist together, only at conduit 8a, 8 ' a extends towards grand portion 6,6 ' reverse inclination respectively.So same assembly is differentiated with the only additional a of same symbolic representation.

Racket protector structure of the present invention is applicable to 9 to inboard 10 the inclination through wires holes from the racket outside, and can utilize injection mo(u)lding to produce in a large number, is installed in frame respectively and is combined into one, and it is very convenient to operate.

Claims (3)

1, a kind of racket protector structure, it is characterized in that forming by the identical relative fit of two halves sheet, half and half comprises flat rectangular, have parallel in fact inner surface and outer surface, a rectangular side is section linearly, and another opposite sides is the waveform curve section with alternate peaks portion and paddy portion, and this inner surface is in the peak portion of this waveform curve side, the integrally formed racket that supplies is clapped the conduit that the line threading is used, and is angle with respect to this inner surface and extends.

2, racket protector structure as claimed in claim 1 is characterized in that, this conduit is forward to extend towards this peak portion protuberance direction with respect to this inner surface.

3, racket protector structure as claimed in claim 1 is characterized in that, this conduit is that relative this inner surface is towards the reverse extension of this peak portion protuberance direction.
