具有柄部內仁結構之匹克拍及其製造方法Pickle racket with handle inner core structure and manufacturing method thereof

本發明係有關一種具有柄部內仁結構之匹克拍及其製造方法。The present invention relates to a pickle paddle with a handle inner core structure and a manufacturing method thereof.

習知匹克拍如以碳纖維材質成型者，主要會採用吹氣成型方式製作，然而採用吹氣成型方式製作容易發生漏氣現象，進而影響到球拍的品質。另種習知碳纖維材質匹克拍，於柄部與拍面採用一次式發泡成型，其內部構造不能提供避震效果，因而仍具有進步的空間，再者，習知的碳纖維材質匹克拍柄部的後套結構係由外部加裝固定，造成球拍增加額外的重量，且加裝的後套也會因長期使用、溫度或撞擊發生脫離。It is known that if a carbon fiber material is used for a peak racket, it is mainly made by blowing molding, but the blowing molding method is prone to air leakage, which in turn affects the quality of the racket. Another known carbon fiber material peak racket uses one-time foaming molding for the handle and the racket face, and its internal structure cannot provide a shock-absorbing effect, so there is still room for improvement. Moreover, the back cover structure of the handle of the known carbon fiber material peak racket is fixed by external attachment, which causes the racket to add extra weight, and the attached back cover may also come off due to long-term use, temperature or impact.

是以，針對上述習知結構所存在之問題點，如何開發一種更具理想實用性之創新結構，實使用消費者所殷切企盼，亦係相關業者須努力研發突破之目標及方向；有鑑於此，創作人本於多年從事相關產品之製造開發與設計經驗，針對上述之目標，詳加設計與審慎評估後，終得一確具實用性之本發明。Therefore, in view of the problems existing in the above-mentioned known structures, how to develop an innovative structure that is more ideal and practical, and realize the earnest expectations of consumers, is also the goal and direction that the relevant industry must strive to develop breakthroughs. In view of this, the creator, based on many years of experience in manufacturing, developing and designing related products, has designed and carefully evaluated the above-mentioned goals in detail, and finally obtained this invention that is truly practical.

即，本發明之主要目的，係在提供一種具有柄部內仁結構之匹克拍及其製造方法；其所欲解決之問題點，係針對習知碳纖維材質匹克拍的柄部與拍面皆係一次式成型，不具避震效果，再者，習知的碳纖維材質匹克拍柄部的後套結構係採用外部加裝固定，不僅令球拍整體產生額外的重量，加裝後的強度也容或有改善空間。That is, the main purpose of the present invention is to provide a pickle racket with a handle inner core structure and a manufacturing method thereof; the problem it aims to solve is that the handle and the racket face of the conventional carbon fiber material pickle racket are both formed in one step, and have no shock-absorbing effect. Furthermore, the rear cover structure of the handle of the conventional carbon fiber material pickle racket is fixed by external attachment, which not only makes the racket as a whole generate additional weight, but also leaves room for improvement in strength after attachment.

本發明主要係藉由包含一拍面及一成型於該拍面一端的柄部，該柄部包含一殼部，其中該殼部末端可一體成型有一後套部，該殼部內部形成有一容室空間，該容室空間內部係完整容置一塑性發泡加壓成型的芯部，其中該芯部係完整穩固貼接於該殼部的容室空間內壁面。The present invention mainly comprises a racket face and a handle formed at one end of the racket face, wherein the handle comprises a shell, wherein the end of the shell can be integrally formed with a rear cover, and a chamber space is formed inside the shell, and a core formed by plastic foaming and pressure molding is completely accommodated inside the chamber space, wherein the core is completely and stably attached to the inner wall surface of the chamber space of the shell.

藉此，本發明柄部具有內部發泡體，即塑性發泡成型的芯部而具有避震效果，且該芯部係完整穩固貼接於該殼部的容室空間內壁面，並可於該柄部末端一體成型一後套部，除可在製程上減少另外組裝後套的程序外，還可增進強度並減輕柄部重量，預成型的芯部也有助於製作具特殊形狀的柄部，且本發明製作皆係藉由加熱發泡成型，不會因吹氣成型而產生漏氣現象而影響球拍品質者。Thus, the handle of the present invention has an inner foam body, that is, a core formed by plastic foaming and has a shock-absorbing effect, and the core is completely and stably attached to the inner wall surface of the chamber space of the shell, and a rear cover can be integrally formed at the end of the handle. In addition to reducing the procedure of assembling the rear cover in the manufacturing process, the strength can be increased and the weight of the handle can be reduced. The pre-formed core is also helpful in making a handle with a special shape, and the manufacturing of the present invention is all through heat foaming molding, and there will be no leakage due to blow molding that affects the quality of the racket.

請參閱圖8所示，本發明還揭露一種具有柄部內仁結構之匹克拍之製造方法，其步驟包含：Please refer to FIG. 8 , the present invention also discloses a method for manufacturing a pickle paddle having a handle inner core structure, the steps of which include:

A.製備芯部：製備一芯部模具A，通過將熱塑性發泡材置入並加熱成型而令芯部模穴B形成一芯部半成品30，該芯部半成品30為僅發泡成型至80%以下，例如50%程度的形態，該芯部半成品30發泡成型具有一連結端31及一體成型於該芯部半成品30末端位置的半成型後套部32，半成型後套部32具有朝向末端漸擴的寬度。A. Prepare the core: prepare a core mold A, place a thermoplastic foam material into the core cavity B and heat-mold it to form a coresemi-finished product 30. The coresemi-finished product 30 is foamed to less than 80%, for example, 50%. The coresemi-finished product 30 is foamed to have a connectingend 31 and a semi-moldedrear sleeve 32 integrally molded at the end of thecore semi-finished product 30. The semi-moldedrear sleeve 32 has a width that gradually expands toward the end.

B.排疊纖維材：將芯部半成品與纖維紗料半成品一同排疊放置於球拍成型模具中，具體而言可以先將該芯部半成品30包覆於一至若干層纖維紗料半成品40中，纖維紗料半成品40在未加熱成型前呈軟質狀態，再一同放置於球拍成型模具中。球拍成型模具C具有一柄部成型模穴E及一與柄部成型模穴E連相通的拍面成型模穴D，令包覆纖維紗料半成品40的芯部半成品30置入柄部成型模穴E，並將連結端朝向拍面成型模穴D，同時將預先製作的拍面半成品也置入拍面成型模穴D，或直接以纖維紗料半成品堆疊放入拍面成型模穴D，準備製作為柄部與拍面。B. Stacking fiber materials: Stack the core semi-finished product and the fiber yarn semi-finished product together and place them in the racket forming mold. Specifically, the coresemi-finished product 30 can be firstly wrapped in one or more layers of fiber yarnsemi-finished product 40. The fiber yarnsemi-finished product 40 is in a soft state before being heated and formed, and then placed together in the racket forming mold. The racket forming mold C has a handle forming mold cavity E and a racket face forming mold cavity D connected to the handle forming mold cavity E. The coresemi-finished product 30 coated with the fiber yarnsemi-finished product 40 is placed into the handle forming mold cavity E, and the connecting end is facing the racket face forming mold cavity D. At the same time, the pre-made racket face semi-finished product is also placed into the racket face forming mold cavity D, or the fiber yarn semi-finished product is directly stacked and placed into the racket face forming mold cavity D, ready to be made into the handle and the racket face.

C.加熱成型：將球拍成型模具C加熱，纖維紗料半成品即受加熱而開始成型，同時芯部半成品40進行再發泡並成型至發泡度100%或接近100%，進行再發泡的芯部半成品即提供壓力而使纖維紗料半成品受到加壓成型，最終使芯部半成品成型為芯部，纖維紗料半成品成型為殼部，且因殼部與拍面一同成型，也使殼部與拍面結合為一體。C. Heating and molding: The racket molding mold C is heated, and the fiber yarn semi-finished product is heated and begins to be molded. At the same time, the coresemi-finished product 40 is re-foamed and molded to a foaming degree of 100% or close to 100%. The re-foamed core semi-finished product provides pressure to pressurize and mold the fiber yarn semi-finished product. Finally, the core semi-finished product is molded into the core, and the fiber yarn semi-finished product is molded into the shell. Since the shell is molded together with the racket face, the shell and the racket face are also combined into one.

藉此，本發明柄部藉由內部含有以發泡體成型的芯部30A而具有避震效果，且該芯部30A係完整穩固貼接於該殼部內部，並令該柄部末端一體成型一後套部60，除可在製程上減少另外組裝後套的程序外，還可增進強度並減輕柄部70重量者。Thus, the handle of the present invention has a shock-absorbing effect by containing acore 30A formed of a foam body inside, and thecore 30A is completely and firmly attached to the inside of the shell, and arear cover 60 is integrally formed at the end of the handle. In addition to reducing the procedure of assembling the rear cover in the manufacturing process, the strength of thehandle 70 can also be increased and the weight can be reduced.

此外，在製備芯部時可以利用芯部半成品30預先成型出最終柄部需要的大致結構外型，例如半成型後套部，在進行排疊纖維材後，纖維紗料半成品自然形成漸擴的末端外型，待加熱成型後即具有一體成型的後套部，以芯部半成品提供類似骨架的功能，而有助於正確地將軟質的纖維紗料半成品排列、成型為預定目標結構，降低生產難度並提高柄部外型的變化性。In addition, when preparing the core, the coresemi-finished product 30 can be used to pre-form the approximate structural shape required for the final handle, such as a semi-formed rear sleeve. After stacking the fiber materials, the fiber yarn semi-finished product naturally forms a gradually expanding end shape, and after heat forming, it has an integrally formed rear sleeve. The core semi-finished product provides a skeleton-like function, which helps to correctly arrange and shape the soft fiber yarn semi-finished product into a predetermined target structure, reduce the difficulty of production and increase the variability of the handle shape.
