Description

Seperate covering for racket

The utility model relates to a kind of Racket coat, particularly relates to a kind of separate type sheath of racket.

Racket had Racket coat is not simple decoration function for one; it has more the damping effect of protection racquet frame surface and square stance; therefore; whether the effect that the quality of a sheath has also influenced in the racket use virtually can perform to certain level; with regard to the high frame racket that has double through wires hole arranged side by side at present; as Fig. 1; shown in 2; because its framework 1 periphery is provided with the two rows through wires hole 2 that is mixed with that intersects arranged side by side; therefore; in its sheath 3 designs; promptly need on its bottom surface, to be provided with the bar nail 4 of collocation through wires hole 2; for being fixed in the protection that wears that reaches netting twine 5 on the framework 1; though sheath has the effect of decorating shock-absorbing, still exist undesirable part on actual the use:

A, this class racket are to belong to a kind of high frame racket, the frame face area of framework itself and weight surpass general racket in design already, therefore, also looseer in 3 designs of its sheath than traditional, to coat the periphery of framework 1, improved the weight of framework 1 virtually again, when being moved, the user causes excessive burden, must pay big muscle power during motion, tired easily, even move injury.

B, because this type of racket has the two arranged side by side through wires holes 2 of design, therefore the bar nail 4 that is nested with in the through wires hole 2 also is a mode arranged side by side, though therefore its be adopt one-body molded or separate the moulding installation with sheath, all can cause the difficulty of making and installing, because, as make sheath and bar nail in integrated mode, then certainly will consider the arrangement position of bar nail, so, then seem comparatively complicated during molding, cost also improves relatively, if bar nail and sheath are installed separately, has then also increased its difficulty of installing.

C, shown in Figure 2, sheath 3 generally is only to be coated on the outer peripheral edges of framework 1, yet, waving square stance because of racket is not only more than waist, sometimes also need to follow the ball or bend over and bat, therefore, the racket framework has the phenomenon of contacting to earth unavoidably, causes racket outermost periphery (being the link position of its inner peripheral and outer peripheral edges) friction impaired.

The purpose of this utility model is the separate type sheath that is to provide a kind of racket, and the weight of this sheath is light and can protect the outermost periphery of framework.

The separate type sheath of this racket of the present utility model includes two monolateral sheaths, wherein a monolateral sheath fit portion and curved arc face and respectively be provided with sticking part and location division, on the sticking part bottom surface respectively according to the one-body molded corresponding nail in the position of through wires hole, be fixed on the framework for pegging graft, the location division then tightly fits in the curved arc face; Another monolateral sheath is identical with above-mentioned monolateral sheath design, and is fixedly arranged on the another side of framework;

The cross sectional shape of racket framework is made of toward the curved arc face that inner peripheral extends the concave part of its outer peripheral edges central authorities and both sides thereof, above-mentioned through wires hole be according on the interior slightly concave part of curved arc face in regular turn around setting; Offer on the periphery of racket framework corresponding two be arranged in unidirectional around through wires hole, and the distribution of mutual cross-shaped attitude is worn fork for netting twine and is handed over around being woven into wire side, simultaneously, netting twine is worn around preceding and is covered one group of sheath on prior to the framework side face.

Be elaborated below by preferred embodiment and accompanying drawing separate type sheath to the utility model racket, in the accompanying drawing:

Fig. 1 has two high frame rackets of through wires hole side by side to cooperate the schematic perspective view of sheath in the past.

Fig. 2 is the A-A generalized section of Fig. 1.

Fig. 3 is the perspective exploded view of the utility model sheath and framework.

Fig. 4 is the combination schematic perspective view of the utility model sheath and framework.

Fig. 5 is the combination generalized section of the utility model sheath and framework.

The separate type sheath of the utility model racket, shown in Fig. 3～5, it is solid one group of sheath 20 of cover on racket 10 frameworks 11.

The cross sectional shape of framework 11 is made of toward the curved arc face 112 that the inner peripheral continuity protrudes out the concave part 111 of its outer peripheral edges central authorities and both sides thereof, be adjacent to the concave part 111 of curved arc face 112 in slightly and be provided with to be and intersect through wires hole 113 arranged side by side, through wires hole 113 is set to predetermined hole count along the periphery ring winding of framework 11.

Sheath 20 comprises two

monolateral sheaths

21,22, monolateral sheath 21 is with plastics one ejection formation, it forms and can cooperate the sticking part 211 of being close to above-mentioned concave part 111, and the location division that is the curved arc shape 212 of the curved arc face 112 that is nested, and on sticking part 211 bottom surfaces, form relative edge's through wires hole 113 and be the bar nail 213 of hollow form, be fixed in the through wires hole 113 for insertion, monolateral sheath 21 is fixed on the framework 11; Monolateral sheath 22 is identical with monolateral sheath 21, also is provided with sticking part 221, location division 222 and bar nail 223, and is fixedly arranged on the another side of framework 11 with this.

During its combination, be that the nail of the bar on the two

monolateral sheaths

21,22 213,223 is plugged in the through wires hole 113 of framework 11 outer peripheral edges both sides successively, weaving netting twine 30 in regular turn according to the position of through wires hole 113 again after it is fixing makes framework 11 inner edges form wire side, use for batting, at this moment, sheath group 20 also firmly covers on framework 11 outer peripheral edges, and the end of monolateral sheath 21 location divisions 212 extends and covers in framework 11 outer peripheral edges and inner peripheral joint 114 and on interior position (being the outermost peripheral region of racket framework) a little.

Major advantage of the present utility model is, utilize two

monolateral sheaths

21,22 design, make on its through wires hole that is installed on single ender separately 113, do not receive the part that sheath coats and make to have on its central concave part 111, so, sheath group 20 overall weight under the situation of same length obvious its must be lighter than sheath in the past, therefore, weight on the framework also reduces a lot of certainly, so, weight saving is for the user and Yan Dangke reduces the burden that motion the time is exerted oneself thus, and it is lighter that its use is hit, indefatigability, also can prevent the generation of unexpected injury etc., though the weight of this sheath only is alleviating of part, it is to a tennis player, especially for the court star, obvious effect can be arranged.

In addition, the sheath of this separate type was easier when die sinking is made, so its molding cost also relatively reduces.

In addition; the utility model extends the outermost peripheral region that is covered in framework 11 with the location division 211,221 of

monolateral sheath

21,22; therefore; on framework 11 surfaces might produce the part of collision with ground; by the protection of

monolateral sheath

21,22, can avoid framework 11 fully because of damaged in collision (as shown in Figure 5).
