背景技术 Background technique

[0004] 棒球球棒和垒球球棒的生产商一直致力于开发一种球棒,该球棒能够呈现出增加的耐用性以及改进的性能特性、挠性、和触感。 [0004] baseball bat and softball bat manufacturers have been working on a bat, the bat can exhibit increased durability and improved performance features, flexibility, and touch. 已经开发出了具有单壁结构的中空球棒,并且最近,出现了具有多壁结构的中空球棒。 Has developed a bat having a single hollow wall structure, and recently, a bat having a plurality of hollow wall structure.

[0005] 单壁球棒在其筒身部位通常包括单管状弹簧。 [0005] in which single-wall bat barrel portion generally comprises a single tubular spring. 多壁筒身在其筒身部位通常包括两个或更多个管状弹簧或类似结构,它们可以是相同的或不同的材料组成。 Multi-wall barrel at its barrel portion typically comprises two or more tubular spring or the like, which may be the same or different materials. 通常,这些多壁球棒中的管状弹簧通常或者彼此接触,使得它们构成摩擦接合点,通过焊接或粘合胶而彼此结合,或者彼此分离形成无摩擦接合点。 Typically, these multi-wall bat tubular spring is typically either contact each other, so that they form a friction joint, by welding or adhesive glue bonded to each other, or formed separately from each other without friction joint. 如果使用结构粘合剂或其它结构粘合材料将管状弹簧结合起来,那么筒身基本上为单壁结构。 If other structural or structural adhesive bonding material to combine the tubular spring, the barrel is substantially single-walled structure.

[0006] 中空球棒通常表现出被称为“蹦床效应”的一种现象,其主要是指由于球棒与球之间的动态耦合(dynamic coupling)引起的离开球棒筒身的球的反弹速度。 [0006] Hollow bats typically exhibit a phenomenon called "trampoline" effect, which refers mainly to rebound away from the bat barrel due to the dynamic coupling ball (dynamic coupling) between the bat and the ball caused speed. 通常希望构造一种具有高“蹦床效应”的球棒,从而一旦接触,球棒就可为所投掷的球提供高反弹速度。 Bat is often desirable configuration having a high "trampoline effect", so that once contact with the bat can provide a high rebound speed of the thrown ball.

[0007] 发展多壁球棒的努力方向是增加容许的筒身挠曲度,使其超过典型单壁和实木设计中可以实现的挠曲度。 [0007] The multi-wall bat efforts direction is to increase the allowable deflection of the barrel, so that deflection than typical single wall design and wood can be achieved. 这些多壁结构通常提供更大的筒身挠曲度,同时不会使应力增加超过筒身材料的材料使用极限。 These multi-wall structures generally provide greater deflection of the barrel, while not increasing stress exceeds the material limits the use of material barrel. 因此,多壁筒身通常更有效地将能量回传给球。 Therefore, multi-walled barrel is usually more efficient energy back to the ball. 通常,通过消除筒身层之间的剪切界面的相互影响来降低筒身刚度,使得多壁球棒实现更高的性能。 Typically, the stiffness of the barrel is reduced by eliminating the interaction between the barrel of the shear layer interface, so that the multi-wall bat to achieve higher performance. 较低的筒身刚度减少了很大程度上影响效率的球的变形,并增加了筒身的变形。 Flashlight lower stiffness reduces distortion largely affect the efficiency of the ball, and increases the deformation of the barrel. 筒身变形在使碰撞能量返回至球方面更为有效,因此产生了改进性能的效果。 Barrel deformation is more effective that the collision energy is returned to the ball connection, thus producing the effect of improving performance.

[0008] 图1示出了多壁球棒100的实例。 [0008] FIG. 1 shows an example of a multi-wall bat 100. 球棒100的筒身102包括内壁104,通过界面剪切控制区(ISCZ)IOS或层,例如弹性材料层、摩擦接合点、抑制结合层、或其它适当的剪切控制区或层,内壁与外壁106分离。 102100 bat barrel includes an inner wall 104, through the interface shear control zone (ISCZ) IOS or layer, such as an elastic material layer, a friction joint, inhibit the binding layer, shearing or other suitable control region or layer, with the inner wall the outer wall 106 separated. 内壁104和外壁106中的每个通常包括由一种或多种纤维加固合成材料制成的一个或多个层片(ply) 110。 Each generally comprises one or more plies of composite material reinforced by fibers made of one or more (ply) 110 inner wall 104 and outer wall 106. 另外或可替换地,内壁104和外壁106之一或都可以包含诸如铝的金属材料。 Additionally or alternatively, the inner wall 104 and an outer wall of a metal material or can contain one of 106 such as aluminum.

[0009] 多壁球棒不同于单壁球棒的一个方面是,通过多壁筒身中的ISCZ,即通过筒壁之间的用来消除这些壁之间的剪切界面的相互影响的区域,没有剪切能量的传递。 [0009] Multi-wall bat differs from a single-wall bat is, through the multi-wall barrel ISCZ, i.e. to between the cylindrical wall by eliminating the interaction of the interface between the shear region of the walls, there is no transfer shear energy. 应变能平衡的结果是,在单壁筒身中产生剪切变形的该剪切能量被转换为多壁筒身中的弯曲能量。 Strain energy balance result, a shear deformation of the shear energy is converted to strain energy in the multi-wall barrel in a single barrel wall. 并且由于在传递能量的过程中弯曲变形比剪切变形更为有效,所以多壁球棒的壁通常比单壁设计表现出更低的应变能损失。 Since the bending deformation and the energy transfer process is more efficient than shear deformation, the multi-wall bat walls typically exhibit lower strain energy loss than a single wall design. 因此,对于产生有效的球棒-球碰撞动能或更有效的动态耦合“蹦床效应”来说,多壁筒身通常优于单壁筒身。 Thus, for the production of an effective bat - kinetic or dynamic coupling ball collision more effective "trampoline" effect, it is usually better than multi-wall barrel barrel wall. [0010] 为了示例的目的,图2示出了典型木质球棒筒身、典型单壁球棒筒身、及典型双壁球棒筒身的相对性能特性的曲线对比。 [0010] For purposes of illustration, FIG. 2 shows a graph of comparison of typical wood bat barrel, a typical single-wall bat barrel, and the relative performance characteristics of a typical double-wall bat barrel. 如图2所示,双壁球棒通常比单壁球棒和木质球棒沿筒身长度的性能更好。 2, double-walled bats usually performs better than single-wall bat barrel and the wood along the length of the bat. 虽然双壁球棒通常沿筒身长度产生了改进的效果,但是当碰撞在离开筒身的“最有效击球点”处发生时,这些效果还是会降低的。 Although the double-wall bat barrel generally along the length of the produced improved results, but when a collision occurs at the "sweet spot" to leave the barrel, these effects will still be reduced.

[0011] 最有效击球点是从球棒到球的能量传递最大而到打球者手部的传递能量最小的位于筒身上的碰撞位置。 [0011] The sweet spot is the energy transfer from the ball bat to transfer energy to the maximum and minimum golfer hand collision located cylindrical body. 最有效击球点通常位于球棒的敲击中心(COP)与棒的前三个基本振型的重叠之间的交叉点处。 At the intersection sweet spot of the bat it positioned generally between the center of percussion (COP) and the fundamental mode of the first three bars overlap. 当球棒以其基本弯曲模式振动时,该位置不会移动,该位置通常在距离筒身的自由端大约4至8英寸处(仅为了示例的目的,在图2中该位置被示为距离筒身自由端6英寸处。因此,当球碰撞最有效击球点时,球棒振动能量损失最小,并且挥动球棒的打球者只能感到很小的振动或感觉不到振动。 When the bat in its fundamental bending mode of vibration, this position does not move, this position is usually about 4-8 inches from the free end of the barrel (only for purposes of example, FIG. 2 in this position is shown as a distance Flashlight free end 6 inches. Therefore, when the ball hits a sweet spot, bat vibration energy loss is minimized, and the golfer swing the bat can only feel a small vibration or feel the vibration.

[0012] 当球撞击球棒的位于主振动节点或COP附近以外的位置时,球棒变形至其基本和谐振(harmonic)振型。 [0012] When in the position other than the vicinity of the main vibration node or COP ball striking bat, bat and modification to the basic resonance (Harmonic) modes. 此变形的大小是被激发的振型以及从振动节点和COP至碰撞位置的距离的正函数。 This modification is a direct function of the magnitude of the excited modes and the distance from the vibration nodes and the collision position to the COP. 如果球棒进入其振型的加速度相当高,并且处于特定频率下,则球棒将振动并产生激波。 If the bat into its rather high acceleration modes, and is at a specific frequency, vibration and shock waves bat.

[0013] 激波以高速传播,并且根据其能量实际上可以刺痛打球者的手部。 [0013] In a high speed shock wave propagation, and may actually sting player's hand according to its energy. 通常,由于远离COP的碰撞所导致的和/或由于远离球棒主振动节点的碰撞引起的模态振动所导致的刚体转动造成球棒把手上的位移,从而产生刺痛。 Typically, due to the rigid and / or vibrations due to collision modes away from the main node of vibration caused by collision of the bat COP away from the rotation caused due to displacement caused by the bat handle, resulting in tingling. 这种特性的碰撞通常被称为“偏离中心的撞击”,因为球棒筒身的“最有效击球点”通常大约位于其长度的中心,其中COP和第一主振动节点彼此非常接近。 Collision of this nature are commonly referred to as "off-center impact," because of the bat barrel "sweet spot" is generally located about the center of the length thereof, and wherein the first main vibration node COP very close to each other. 由于偏离中心的撞击引起的刺痛可能分散打球者的注意力并使其感到疼痛,因此是不期望的。 Tingling due to the impact caused by the off-center may distract the golfer and make it feel pain, and therefore undesirable. 为了使刺痛最小,并改善球棒的“触感”,在由于偏离中心的撞击导致的激波到达球棒把手之前,必须将其吸收或以其它方式使其削弱。 In order to minimize irritation, and to improve bat "feel", the shock due to the impact caused by off-center before reaching the bat handle, must be absorbed or otherwise weaken it.

[0014] 而且,具体地说,由于振动及转动惯量的作用导致的能量损失,使得最有效击球点与筒身的自由端之间的以及最有效击球点与球棒的渐缩或过渡段(以及以外的部分)之间的筒身区域没有表现出最有效击球点处所发生的最优性能特性。 [0014] Further, specifically, the energy loss due to vibration and inertia effects caused, and such that the sweet spot of the bat between the free end of the sweet spot of the barrel or tapered transition barrel region between the segments (portion other than the well) is not optimal performance characteristics of the premises sweet spot occurs. 确实,如图2所示,在典型的球棒中,当碰撞位置移动离开最有效击球点时,筒身性能显著下降。 Indeed, as shown, in a typical bat, when the collision position moves away from the sweet spot, the barrel 2 significant decrease in performance. 因此,打球者需要与被投掷的球进行非常精确的接触,以实现最优效果并避免令人感到刺痛的球棒振动,而这种精确的接触通常是具有极大挑战性的。 Therefore, the need to play with the ball thrown very precise contact, in order to achieve optimal results and avoid people feel the sting of the bat vibration, and this contact is usually accurate with a great challenge.

[0015] 球棒设计中的另一个重要因素是球棒的“反冲点(kick point)”的位置。 [0015] Another important factor in the design of the bat is a bat "kick points (kick point)" position. 反冲点是球棒转动过程中发生的惯性所引起的球棒中的最大曲率点。 Is the point of maximum curvature point recoil bat bat inertia occurring during rotation caused by the. 低反冲点球棒(即仅在手部上方发生弯曲的球棒)可以传递高能量但经常易于滞后,从而导致通常不佳的球棒表现。 Low penalty recoil rod (i.e., bending occurs only in the upper toe hand) can easily pass the high energy but often lag, resulting in generally poor performance of the bat. 相反,因为普通球棒在此位置处的直径相对较大,高反冲点球棒(即在接近筒身的位置发生弯曲的球棒)经常缺少足够大的反冲能量以使球棒有效,从而此类球棒在该区域中非常僵硬。 In contrast, because the average diameter of the bat in this position is relatively large, high penalty recoil rod (i.e., bending occurs near the bat barrel position) often lack sufficient energy to recoil effective bat, such bat so that in this region is very stiff.

[0016] 因此,存在对于这样的球棒的需要,即该球棒呈现改进的性能、挠性、和触感,特别是当球离开最有效击球点撞击球棒的时候。 [0016] Accordingly, a need exists for such a bat, the bat i.e. exhibits improved performance, flexure, and feel, especially when the ball leaves the sweet spot of the bat striking. 此外,存在对于这样的球棒的需要,即该球棒由于材料的选择和制作(tailoring)而呈现出改进的性能、挠性、和/或触感。 Furthermore, there is a need for a bat, the bat i.e. due to the choice of materials and production (Tailoring) and exhibit improved performance, flexibility, and / or tactile. 该球棒可以是单壁或多壁的组合球棒,并且可以选择性地包含金属或其它适宜的材料。 The bat may be a combination of single-wall or multi-wall ball bat, and may optionally contain a metal or other suitable material.

发明内容[0017] 一方面,由于有计划地布置了球棒筒身中的界面剪切控制区(ISCZ),使得在离开筒身最有效击球点的区域中改进了球棒性能和/或触感。 SUMMARY OF THE INVENTION [0017] In one aspect, because the planned arranged interfacial shear control zone (ISCZ) in the bat barrel, so that the performance improved and the bat / in a region away from the sweet spot of the barrel or touch. 另外或可替换地,ISCZ可以有计划地设置在球棒把手和/或球棒的渐缩段中,以改善这些部分的柔度和整体性能。 Additionally or alternatively, ISCZ may be provided in a planned bat handle and / or the tapered section of the bat, in order to improve overall performance and flexibility of these parts.

ISA区域可被合并到过渡区、把手、和/或球棒的筒身中,以提供振动阻尼、碰撞衰减、刚度控制、增强的挠性、和/或改善的触感。 ISA regions may be incorporated into the transition zone, the handle and / or the barrel of the ball bat to provide vibration damping, impact damping, stiffness control, enhanced flexibility, and / or improved texture.

[0019] 在其它或可替换方面,球棒在位于离开球棒筒身最有效击球点的区域中表现出改进的性能,这是在这些区域中进行分散薄片制作的结果。 [0019] In other aspects or alternatively, bat exhibits improved performance in the bat barrel region located away from the sweet spot, which is the result of dispersing sheet produced in these regions. 通常,在离开最有效击球点的球棒筒身区域中,制作一层或多层或薄片,以增加这些区域中的筒身的径向柔度,即减少径向刚度,使得它们通过改进的筒身力学结构而表现得更类似于筒身的最有效击球点。 Typically, leaving sweet spot of the bat barrel zone, making one or more layers or sheets to increase the radial flexibility of these regions of the barrel, i.e. reducing the radial stiffness, such that they are improved by the Flashlight mechanical structure is far more similar to the sweet spot of the barrel. 此外或可替换地,可以将球棒把手和/或球棒的渐缩段中的一层或多层薄片制作成增加(或降低) 这些区域中的径向柔度。 Additionally or alternatively, the bat handle and / or tapered section of the bat one or more sheets may be made to increase (or decrease) the degree of radial compliance in those regions.

[0020] 在其它或可替换方面,在组合球棒中,一个或多个阻尼元件主要位于球棒的一个或多个抗振节点处或附近,以提供振动阻尼和/或改善的球棒“触感”。 [0020] In further or alternative aspect, the bat in combination, or a plurality of damping elements are mainly located in a plurality of vibration nodes of the ball bat at or near or to provide a vibration damping and / or improved bat " touch. " 阻尼元件可由粘弹性和/或弹性材料、和/或其它减振材料制成,并可位于球棒的筒身、把手、和/或减缩或过渡区中。 By the viscoelastic damping element and / or elastic material, and / or other vibration damping material, it may be located in the bat barrel, a handle, and / or or reduces the transition zone.

[0050] 棒筒身14可以是单壁或多壁结构。 [0050] Shaft 14 may be a single rod or multi-walled structure. 如果它是多壁结构,则筒壁可以由一个或多个界面剪切控制区(ISCZ)分离,如美国专利申请序列号10/903,493中详细描述的。 If it is a multi-wall structure, the cylindrical wall may be separated by one or more interface shear control zone (ISCZ), as described in U.S. Patent Application Serial No. 10 / 903,493 described in detail. 所使用的任何ISCZ优选地具有大约0. 001至0. 010英寸的径向厚度,更优选地是0. 004至0. 006 英寸。 Any ISCZ used preferably has a radial thickness of about 0.001 to 0.010 inches, more preferably 0.004 to 0.006 inches. 可以可替换地使用任何其它适当尺寸的ISCZ。 It may alternatively be any other suitable dimensions ISCZ.

[0051] ISCZ可以包括抑制结合层、摩擦接合点、滑动接合点、弹性接合点、两种不同材料(例如铝和复合材料)之间的界面、或用于将筒身分离成“多壁”的任何其它适宜元件或装置。 [0051] ISCZ may include inhibition of binding layer, a friction joint, sliding joint, flexible joint, the interface between two different materials (e.g., aluminum and composite materials), or for separating the barrel into a "multi-wall" elements or any other suitable means. 如果使用抑制结合层,则其优选地由诸如Teflon® (聚氟乙烯)、FEP(氟化乙烯丙烯)、 ETFE (乙烯基四氟乙烯)、PCTFE (聚三氟氯乙烯)、或PVF (聚氟乙烯)的含氟聚合物材料和/或诸如PMP (聚甲基戊烯)、尼龙(聚酰胺)、或玻璃纸的另外的适宜材料制成。 If inhibit the binding layer, it is preferably made of, the ETFE (vinyl tetrafluoroethylene), PCTFE (polychlorotrifluoroethylene), such as Teflon®, or PVF (polyvinyl fluoride), the FEP (fluorinated ethylene propylene) (poly vinyl fluoride) fluoropolymer material and / or as the PMP (polymethylpentene), made of another suitable material as nylon (polyamide), or cellophane.

[0052] 在一个实施例中,一个或多个ISCZ可以与筒身材料的层形成为一体或嵌入该层内,使得筒体14作为一体/多壁结构。 [0052] In one embodiment, the one or more ISCZ may be formed as one layer of the barrel material or embedded within the layer, such as a cylindrical body 14 integrally / multi-wall structure. 在这种情况下,在筒身至少一端处的筒身层优选地是混合在一起的,以形成一体/多壁结构。 In this case, the barrel at least at one end of the barrel layer preferably are mixed together to form an integral / multi-wall structure. 整个球棒10也可以形成为“一体”。 Throughout the bat 10 may be formed as a "one." 一体棒设计通常是指筒身14、渐缩段16、和棒10的把手12不具有缝隙、插入物、封套、或用来适当加厚筒壁的结合结构。 One rod design generally refers to barrel 14, the tapered section 16, a handle 12 and rod 10 does not have a slit, insert, envelope, or to appropriate binding thickened tube wall. 在这样的设计中,独特的层压层优选地一体形成为筒身结构,使得它们在载荷条件下都能谐调动作。 In such a design, the unique laminate is preferably integrally formed as a barrel structure, such that they can be harmonized operation under load conditions. 为了实现一体设计,棒10的层优选地是共同固化的,因此不是由成串的连接管(插入物或封套)构成的,其中每个管在管的端部具有独立的壁厚。 In order to achieve one design, the layers are preferably co-cured rod 10, and thus not by clusters connecting pipe (insert or envelope) configuration, wherein each of the tube end of the tube has a wall thickness independent.

[0053] 在一个或多个ISCZ周围将筒壁混合成一体结构(类似于将板簧的端部系结在一起)提供了稳定且耐久的装配,特别是对于当碰撞发生在筒身14的末端时。 [0053] In one or more surrounding the cylindrical wall of the mixing ISCZ integral structure (similar to the junction with the end portion of the leaf spring system) provides a stable and durable assembly, particularly for when a collision occurs in barrel 14 when the end. 将多个层压层结合在一起确保了系统作为组合结构而动作,其中没有一层是独立于其它层而工作的。 A plurality of laminated layers together ensures that the system operates as a combined structure, wherein no one is working independently of the other layers. 通过将应力重新分配至筒身末端而降低了局部应力,使得棒的耐用性提高。 By the end of the barrel to redistribute stresses and local stress is reduced, so that durability is improved bar. 在可替换的多壁实施例中,棒和/或筒身层不会在任何一端混合在一起。 Embodiment, the rod and / or the barrel layers are not mixed together at either end of the multi-wall alternative embodiment.

[0054] 一个或多个筒壁优选地每个均由一个或多个复合层片25构成。 [0054] one or more walls of each tube preferably consists of one or more composite plies 25. 构成层片的复合材料优选地是纤维加固的,并且可以包括玻璃纤维、石墨、硼、碳、芳族聚酰胺(如Kevlar® )、陶瓷、金属、和/或任何其它适宜的结构性纤维材料,优选地是环氧形式或另一适宜形式。 Preferably, the composite material constituting the layer is fiber-reinforced sheet, and may comprise fiberglass, graphite, boron, carbon, aramid (e.g. Kevlar® cone), ceramic, metal, and / or any other suitable structural fiber material , preferably in the form of epoxy or another suitable form. 每个复合层片优选地具有大约0. 002至0. 060英寸的厚度,更优选地是0. 003至0. 008 英寸。 Each sheet preferably has a composite layer of about 0.002-.060 inches in thickness, more preferably from 0.003 to 0.008 inches. 可替换地,可以使用任何其它适宜的层片厚度。 Alternatively, any other suitable layer of the sheet thickness.

[0055] 在一个实施例中,棒筒身14可以包括混合的金属-复合结构。 [0055] In one embodiment, the rod 14 may include a barrel mixed metal - composite structure. 例如,筒身可以包括由复合材料制成的一个或多个壁以及由金属材料制成的一个或多个壁。 For example, a body may comprise a composite material made of one or more walls, and made of a metal material, or more walls. 可替换地,复合材料和金属材料可散布于给定的筒壁内。 Alternatively, the composite material and the metallic material may be dispersed within a given barrel wall. 当筒身包括诸如铝部的金属部以及复合部时,可以制作复合部的区域,以实现筒身优化,如下文中详细所述。 When the barrel portion and includes a metal such as the aluminum portion of the composite, the composite can be produced area portion, in order to achieve optimization of the barrel, as described in detail below. 在另一实施例中,可替换地或附加地,诸如高强度碳纳米管复合结构的纳米管可以用在筒身结构中。 In another embodiment, alternatively or additionally, the high strength such as a carbon nanotube composite nanotube structure may be used in the barrel structure.

[0056] 增加棒筒身中壁的数目也增加了棒筒身中容许的挠曲度,而且通过一个或多个ISCZ的有计划布置而将剪切能量转化为弯曲能量。 [0056] increasing the number of bars in the wall of the barrel also increases the rod allowable deflection of the barrel, but also through one or more ISCZ a planned arrangement of curved shear energy into energy. 因此,改进了棒的蹦床效应。 Accordingly, the improved rod trampoline effect. 但是,在现有的多壁棒中,由于碰撞发生在离开最有效击球点越远的位置,筒身性能必然下降得更多, 因此无法在筒身的整个长度上达到最优效果。 However, in the conventional multi-walled rods, since the collision point of leaving the sweet farther position, performance barrel inevitably decreased even more, and therefore can not achieve the best results over the entire length of the barrel.

[0057] 为了该描述的目的,如图3_7、16、和图17所示,棒筒身14被分为三个概念性区域或区。 [0057] For purposes of this description, FIG 3_7,16, and as shown, the rod 14 is divided into three conceptual barrel region or zone 17 of FIG. 第一区域21或“区1”大体从球棒10的渐缩段16延伸至靠近棒筒身14的“最有效击球点”(如上所述)的位置。 21 or "zone 1" of the first region extending substantially from the toe 16 of the tapered section 10 to a position close to the stick barrel "sweet spot" 14 (described above). 第二区域22或“区2”大体从棒筒身14的自由端延伸至靠近最有效击球点的位置。 22 or "zone 2" of the second region extends substantially from the free end of the rod 14 of the barrel to a position near the sweet spot. 第三区域M或“区3”在第一和第二区域21、22之间延伸,并包括筒身14的最有效击球点。 The third region M or "zone 3" between the first and second regions 21, 22 extend and includes a sweet spot of the barrel 14. [0058] 如同区的总数目可以变化一样,这些区的实际尺寸和位置也可以变化。 [0058] As the total number of zones may vary, the actual size and location of these regions may also be varied. 此外,各个区可以具有不同的长度并可占据不同的区域。 Further, each zone may have different lengths and may occupy different regions. 例如,区1可以延伸到球棒10的渐缩段16, 沿筒身的长度(以及超出该长度)可勾画出无数多的区,区3可窄于区2,等等。 For example, region 1 may extend into the tapered section 16 of the ball bat 10, along the length of the cylinder body (the length and beyond) can be sketched more numerous and Zone 3 may be narrower than region 2, and so on. 因此,附图中示出的特定区1-3仅是用于更容易进行描述。 Accordingly, the drawings illustrated in specific regions 1 to 3 are merely used to more easily described.

[0059] 为了改进区1和/或区2的筒身性能,可以采用分离的“多壁”方法,该方法是通过一个或两个区中的ISCZ的有计划布置而建立的。 [0059] In order to improve performance and the barrel zone 1 / zone 2 or may be a "multiwall" separation method, which is one or two zones a planned arrangement ISCZ established. 在一个筒身实施例中,如图4所示,第一ISCZ 30位于棒筒身14的区3中。 In one embodiment the barrel embodiment shown in Figure 4, the first ISCZ 30 is located in the region of 14 bar barrel 3. 第一ISCZ 30优选地位于棒筒身14的中轴处或附近,在该位置筒身14中的剪切应力是最高的。 The first ISCZ 30 is preferably located near the axis of the rod or the barrel 14, the shear stress in this position the barrel 14 is the highest. 以这种方式,优化量的剪切应力可被转换成弯曲应力。 In this way, optimize the amount of shear stress can be converted into bending stresses. 第一ISCZ 30可以可替换地位于棒筒身14的区3中的任何其它径向位置处。 The first ISCZ 30 may alternatively be located at a region of the rod 14 in the barrel 3 in any other radial position. 如果筒身14由均勻的各向同性层制成,则中轴大体位于筒壁的径向中点处。 If barrel 14 is made of a homogeneous isotropic layer, the axis substantially at the radial midpoint of the barrel wall. 如果在筒身14中使用了不只一种复合材料,和/或如果材料不是均勻地分布,则中轴可以位于能够易于确定的不同位置处。 If used at different locations than a composite material, and / or if the material is not uniformly distributed, may be located in the central axis can be easily determined in the barrel 14.

[0060] 为了便于描述,认为图4-7所示实施例中使用的复合筒身材料是均勻的各向同性层,从而筒身14的中轴大体位于筒壁的径向中点处。 [0060] For ease of description, that the embodiment shown in FIGS. 4-7 Flashlight composite material used is homogeneous isotropic layer, so that the central axis of barrel 14 is located radially substantially at the midpoint of the barrel wall. 但是实际上,复合材料和/或金属材料的任何适宜的组合均可用于构造筒身14,从而中轴可位于筒身14中的其它位置处。 In practice, however, any suitable composite material and / or combinations of materials can be used in a metal barrel 14 is configured so that the central axis may be located at other locations in the barrel 14. 而且,一旦ISCZ被添加到筒身14上,则ISCZ将筒身14分成两个筒壁,每个筒壁具有自己的中轴,如美国专利申请序列号10/712,251中所详细描述的。 Moreover, once the ISCZ 14 is added to the barrel, the barrel 14 into two ISCZ the tubular wall, each tubular wall having its own axis, as described in detail in U.S. Patent Application Serial No. 10 / 712,251 is .

[0061] 返回图4所示的实施例,区1包括两个ISCZ 32、34,并且区2包括两个ISCZ 36、 38。 [0061] Returns the embodiment illustrated in FIG. 4, zone 1 comprises two ISCZ 32,34, and region 2 comprises two ISCZ 36, 38. ISCZ 32、;34、36、38中的每一个均可以大体位于径向筒身厚度的三分之一处,或者可以以其它方式定位。 ISCZ 32,; 34, 36 in each can be located at substantially one third of the radial thickness of the barrel, or may be otherwise positioned. 通过将两个ISCZ定位在棒筒身14的区1和区2中的每个区中,这些区域必然形成为三壁结构,并因此表现出与必然为双壁结构的区3相比而言增加的挠曲度。 ISCZ by two rods positioned in each barrel zone region 14 of zone 1 and 2, these regions must form a three-wall structure, and therefore necessarily exhibit compared to a double-walled structure in terms of area 3 increased deflection. 因此,区1和区2的筒身挠曲度和蹦床效应相对于区3提高了,从而使得它们更接近棒筒身14的区3的性能。 Thus, barrel deflection and trampoline effect zones 1 and 2 with respect to the region 3 can be improved so that they are closer to the properties of the region 14 of the rod 3 barrel. 因此,当球在区1或区2处撞击筒身14时,筒身14产生蹦床效应,该蹦床效应更接近在球棒最有效击球点处产生的蹦床效应。 Thus, when the ball hits the barrel 2 in zone 1 or 14, a body 14 generates trampoline effect, closer to the trampoline effect trampoline effect produced at the most effective point of hitting bat.

[0062] 在图4所示的实施例中,ISCZ 32、34、36、38被定位成使得它们与区3中的第一ISCZ 30是连续的。 [0062] In the embodiment illustrated in Figure 4, ISCZ 32,34,36,38 such that they are positioned in the region 3 first ISCZ 30 is continuous. 此外,区1中的ISCZ 32、;34与区3中的ISCZ 36、38基本对称。 In addition, the region 1 ISCZ 32,; 34 and in region 3 ISCZ 36,38 substantially symmetrical. ISCZ 32、 ;34、36、38中的一个或多个可以可替换地与第一ISCZ 30不连续,并且区1中的ISCZ 32,34 可以与区3中的ISCZ 36,38不对称,下文中将进一步描述。 ISCZ 32,; 36, 38 in the one or more may alternatively be discontinuous with the first ISCZ 30, and the region 1 ISCZ 32,34 may be asymmetrically in the region 3 ISCZ 36,38, the It will be described further below.

[0063] 在图5和6所示的筒身实施例中,在棒筒身14的区1中设置比区2中更多数目的ISCZ。 [0063] The barrel as shown in FIGS. 5 and 6 embodiment, provided more than the number of ISCZ region 2 in the rod region 14 of the barrel 1. 由于转动惯量的作用,这样的布置可能是优选的。 Since inertia effects, such an arrangement may be preferred. 在典型的棒挥动过程中,由于与区2相比,区1相对更靠近棒把手12,所以区1中产生的转动惯量小于区2中产生的转动惯量。 In a typical process the rod swing as compared with the region 2, a region relatively closer to the handle bar 12, the moment of inertia of area 1 is less than the moment of inertia generated in region 2 is produced. 因此,区1中的棒性能通常劣于区2中。 Thus, the performance of the rod is generally inferior in zone 1 zone 2. 为了抵消性能上的差异,在图5和6所示的实施例中,在区1中包括比区2更多数目的ISCZ,以使区1中的筒身挠曲度增大到大于区2中的程度。 In order to cancel the difference in performance, in the embodiment shown in FIG. 5 and 6, in zone 1 comprises a number of more than 2 zones ISCZ, so that the deflection of the barrel zone 1 zone 2 increased to greater than the extent.

[0064] 在图5所示的筒身实施例中,连续的ISCZ 40大体在筒壁的径向中点处贯穿区1、 区2、和区3。 [0064] In the barrel embodiment shown in FIG. 5, the continuous ISCZ 40 through a generally radial zone 1 at a midpoint of the barrel wall, region 2 and region 3. 两个分离的不连续的ISCZ 42,44位于区1中并处于ISCZ 40与棒筒身14的中轴之间,同时另外的不连续的ISCZ 46位于区1中并处于ISCZ 40与棒筒身14的外表面之间。 Two separate discontinuous ISCZ 42,44 located in zone 1 and between the ISCZ 40 and the central axis of the barrel 14 of the rod, while the additional discontinuous ISCZ 46 located in zone 1 and the rod 40 in the barrel ISCZ between the outer surface 14. 因此,区1包括总共四个ISCZ,使得筒身14在区1中必然表现为类似于5壁结构。 Thus, Zone 1 includes a total of four ISCZ, such that the barrel 14 necessarily behaves like a wall structure 5 in the region 1. 区2包括位于ISCZ 40与棒筒身14的中轴之间的一个不连续ISCZ 48,以及位于ISCZ 40与棒筒身14的外表面之间的另外的不连续ISCZ 50。 Zone 2 includes a discontinuous ISCZ between the ISCZ 40 and the central axis of the rod 14 of the barrel 48 between the other, and the outer surface of the rod 40 and the barrel 14 ISCZ discontinuous ISCZ 50. 因此,区2包括总共三个ISCZ,使得筒身14在区2中必然表现为类似于4壁结构。 Thus, Zone 2 includes a total of three ISCZ, barrel 14 such that the wall structure 4 is necessarily appears in zone 2 is similar.

[0065] 在图6所示的筒身实施例中,区3包括大体位于筒壁的径向中点处的一个ISCZ 60。 [0065] In an embodiment, a region 3 including ISCZ 60 is located substantially at the midpoint of the radial wall of the cylinder barrel shown in FIG. 6. 区1包括位于筒壁的径向中点与外表面之间的两个ISCZ 62,64,以及位于筒壁的径向中点与筒身14的中轴之间的一个ISCZ 66。 Area 1 comprises two radial midpoint ISCZ 62,64 located between the outer surface of the cylindrical wall, and one ISCZ 66 located between the central axis of the cylindrical wall of the radial midpoint of the barrel 14. 因此,区1包括总共三个ISCZ,使得筒身14在区1中必然表现为类似4壁结构。 Thus, Zone 1 includes a total of three ISCZ, necessarily it appears that the barrel 14 in zone 1 is similar to the wall structure 4. 区2包括位于筒壁的径向中点与外表面之间的一个ISCZ 68,以及位于筒壁的径向中点与筒身14的中轴之间的一个ISCZ 70。 Zone 2 includes a ISCZ 68 located between the radial midpoint of the barrel wall with an outer surface, and one ISCZ 70 located between the central axis of the cylindrical wall of the radial midpoint of the barrel 14. 因此,区2包括总共两个ISCZ,使得筒身14在区2中必然表现为类似于3壁结构。 Thus, zone 2 comprises a total of two ISCZ, such that the barrel 14 necessarily behaves like wall structure in zone 3 2. 区1中的三个ISCZ62、64、66 和区2中的两个ISCZ 68,70都与区3中的ISCZ 60相连续。 In zone 1 and zone three ISCZ62,64,66 two ISCZ 68,70 2 in both the continuous region 3 ISCZ 60.

[0066] 图5和6所示的筒身实施例示出了这里所预期的设计挠性。 [0066] FIGS. 5 and 6 barrel embodiment shown herein illustrates the desired design flexibility. 例如,区1和区2中的一个或多个ISCZ可以与区3中的一个或多个ISCZ相连续或不连续,区1-3的任何一个区中的一个或多个ISCZ可以位于筒壁的径向中点与外表面之间、位于筒壁的径向中点处或附近、和/或位于筒壁的径向中点与棒筒身14的中轴之间,等等。 For example, a region 1 and region 2 may be one or more of the ISCZ region 3 or more continuous or discontinuous ISCZ, any region in a region 1-3 or more may be located in the barrel wall ISCZ between the radial midpoint and the outer surface of the cylindrical wall radially located at or near the midpoint of, and / or radial axis located at a midpoint of the barrel wall between the rod barrel 14, and the like. 此外,区1和区2彼此可以包括彼此相同数目或不同数目的ISCZ。 Further, Zones 1 and 2 may be the same number or different from each other include a number of ISCZ.

[0067] 重要的是,ISCZ的终点不必特意出现在两个区相遇的位置。 [0067] is important, ISCZ need not meet at the two end positions intentionally region appears. 实际上,ICSZ可以重叠或位于一个以上的区中,并且这些区可以比附图中描述的区更短或更长。 Indeed, ICSZ located or may overlap more than one zone, and these zones may be described in the drawing area than shorter or longer. 而且,可以设置更多或更少数目的区。 Also, you can set more or lesser number of areas. 实际上,这些“区”仅用于示例的目的,而并非为了提供任何类型的实际或理论上的隔断。 In fact, the "region" for the purposes of illustration only, and not to provide any type of actual or theoretical partition. 因此,根据无数的设计,ISCZ可以位于棒筒身14中(以及渐缩段16 和把手12中)的各种各样的位置处,以实现所需的筒身和整体的球棒性能特性。 Thus, according to numerous design, ISCZ rods 14 may be located at barrel (and tapered section 16 and the handle 12) in various positions, in order to achieve the bat barrel and the overall performance characteristics desired.

[0068] 为此,在一些实施例中,可以希望在位于最有效击球点之外的至少一个筒身区域中比位于包括最有效击球点在内的筒身区域中具有更多数目的ISCZ,以便在那些区域中提供改进的筒身挠曲度和蹦床效应。 [0068] For this reason, in some embodiments, it may be desirable to have more than the number located in both sweet spot region of the inner barrel of the barrel in at least one region outside the sweet spot is located in the ISCZ, to provide an improved barrel deflection and trampoline effect in those areas. 此外,在一些实施例中,可以希望在棒的渐缩段与最有效击球点之间的筒身区域中比最有效击球点与筒身自由端之间的区域中包括更多数目的ISCZ,以补偿那些区域中的转动惯量作用的差异。 Further, in some embodiments, it may be desirable in the barrel region between the tapered section of the rod and the sweet spot than in the region between the sweet spot and the free end of the barrel comprises a greater number of ISCZ, in order to compensate for inertia effect of the difference in those areas. 但是可以认识到,根据具体球棒的设计目标,可以在筒身的任何区域(以及球棒的其它部分)中以任何合适的结构设置任何合适数目的ISCZ。 It will be appreciated that, in accordance with particular design objectives of the bat may be provided in any suitable number of any suitable structure ISCZ in any region (as well as other parts of the bat) in the barrel.

[0069] 图7示出了可替换筒身实施例,其中棒筒身14包括金属外部区域80和复合内部区域82。 [0069] FIG. 7 shows an alternative embodiment of the barrel, wherein the barrel 14 includes a metal rod 80 and the outer region of the composite inner region 82. 金属外部区域80优选地通过诸如抑制结合层的适当的ISCZ 86而与复合内部区域82分离。 Preferably the metal outer region 80 and inner region 82 separated from the complex by an appropriate ISCZ 86 such as the inhibition of the binding layer. 可替换地,金属外部区域80与复合内部区域之间的非结合界面本身可以形成ISCZ0 Alternatively, the outer region 80 and the non-metal bonding interface between the composite inner region itself may be formed ISCZ0

[0070] 金属外部区域80优选地包括铝和/或其它合适的金属材料。 [0070] Preferably the metal outer region 80 comprises aluminum and / or other suitable metallic material. 复合内部区域82优选地至少在筒身14的区1和区2中包括一个或多个ISCZ 84,以在那些区域中提供增加的筒身挠曲度。 The composite inner region 82 preferably comprises at least in the region of a barrel 14 and one or more regions 2 ISCZ 84, to provide increased deflection of the barrel in those areas. 由于金属外部区域80的出现,这种混合的金属/复合结构提供了增加的耐用性,同时由于在复合内部区域82的特定区中一个或多个ISCZ的布置,这种混合的金属/复合结构还提供了增加的区域筒身挠曲度的优点。 Due to the presence of the metal outer region 80, the mixed metal / composite structure provides increased durability, and because a particular zone is arranged in the interior region 82 of the composite or plurality of ISCZ, this mixed metal / composite structure barrel also provides the advantage of increased deflection region. 在可替换实施例中,筒身14可以包括复合外部区域和金属内部区域。 In an alternative embodiment, the barrel 14 may comprise a composite metal inner region and outer region.

[0071] 图8示出了典型双壁棒筒身(图8的曲线图中的双壁筒身曲线与图2的曲线图中所示的双壁筒身曲线相同)与“多壁”棒筒身的相对性能特性的曲线对比,其中多壁棒筒身在棒筒身14的区1和区2中结合了附加的ISCZ。 [0071] FIG. 8 shows (the same as a double-walled barrel shown in the graph of FIG double wall barrel curve in the graph of FIG. 8 in the curve 2) is typically a double-walled body and a rod "multiwall" bar graph comparing the relative performance characteristics of the barrel, wherein the barrel incorporates multi-wall bars ISCZ additional bar in the region 14 of barrel 1 and region 2. 如图8所示,通过在棒筒身14的区1和区2中设置附加的ISCZ,与典型双壁棒相比,通常改进了沿筒身14长度的性能。 8, the rod through the barrel 14 in zone 1 and zone 2 to provide additional ISCZ, compared to a typical double-walled rods, generally improves the performance of the 14 along the length of the barrel.

[0072] 图9和10示出了可替换实施例,其中单一连续的ISCZ贯串棒筒身的区1、区3、和区2,并必然形成了双壁棒筒身。 [0072] Figures 9 and 10 illustrate an alternative embodiment wherein the rod throughout a single continuous ISCZ barrel zone 1, zone 3, and zone 2, and is inevitably formed a double-walled barrel rod. 但是,在这些实施例中的单一连续ISCZ与区1、区2、和区3的每一个中的一个以上的层片相交叉,即每个筒壁的厚度在整个筒身长度上是变化的。 However, with a single continuous ISCZ In these embodiments, area 1, area 2, and area of ​​each of the one or more plies 3 intersect, i.e. the thickness of each cylinder wall over the entire length of the barrel is varied . 因此,棒筒身不会表现得类似于典型双壁筒身,该典型双壁筒身在基本相同的径向位置处具有沿筒身长度延伸的单一连续ISCZ。 Thus, the rod does not behave like a typical barrel double-walled barrel, the barrel having a double-wall typically a single continuous ISCZ extending along the length of the barrel substantially at the same radial position.

[0073] 图9示出了包括单一连续ISCZ 90的棒筒身,该ISCZ在区3中比在区1和区2中更靠近筒身14的外表面而延伸。 [0073] FIG. 9 shows a stick barrel including a single continuous ISCZ 90, and extends in the ISCZ than the region 3 closer to the outer surface of the barrel 14 in the region 1 and region 2. 图10示出了包括单一连续“台阶状” ISCZ 92的棒筒身, 该ISCZ在区2中比在区3中更靠近筒身14的外表面而延伸,并且在区3中比在区1中更靠近筒身14的外表面而延伸。 FIG 10 shows a single continuous comprising a "stepped" stick barrel ISCZ 92, and extend the ISCZ than in region 2 closer to the outer surface of the barrel 14 in zone 3 and in zone 3 than in Zone 1 rather it extends closer to the outer surface of the barrel 14. 连续ISCZ无需对称,并且其可以定位成与图9和10所示实施例逆向,或者其可以以任何其它适宜方式定位。 Continuous ISCZ need not symmetric, and which may be positioned with the embodiment shown in FIG. 9 and the reverse embodiment 10, or it may be positioned in any other suitable way. 通过在整个棒筒身的范围内改变单一连续ISCZ的位置,可以增加和/或改变筒身的最有效击球点。 By changing the position of a single continuous ISCZ barrel over the entire range of the rod can be increased and / or changing the sweet spot of the barrel. 在可替换实施例中,连续ISCZ 在较少数目的区或筒身区域中可以与多于一个的层片交叉,使得筒壁的厚度仅在那些区域中发生变化。 Changes only in those areas in thickness alternative embodiment, the continuous ISCZ may cross more than one with a smaller number of plies in the region or regions in the barrel, so that the cylinder wall.

[0074] 可以进一步构思,ISCZ可以位于球棒10的棒把手12和/或渐缩段16中(以对于偏离筒身的撞击提供增加的变形),以在那些区域中提供增加的挠曲度。 [0074] further contemplated, ISCZ rod ball bat 10 may be located in the handle 12 and / or tapered section 16 (deviation from the barrel to provide added impact modification), to provide increased deflection in those areas . 由于弯曲变形所导致的有效能量转移(与剪切变形相反),在棒把手12中使用ICSZ提供了增加的把手柔度。 Since the bending deformation caused by active energy transfer (as opposed to shear deformation), using ICSZ provides increased flexibility in the handle 12 in the handle bar. 此外,当设置更多数目的界面来消散振动能量时,通过使用一个或多个IC^Z来减弱把手12 的振波,改善了棒10的“触感”。 Further, when the number of interface provided to dissipate more vibration energy, by using one or more IC ^ Z Discovering handle 12 to attenuate and improve the "feel" of the rod 10.

[0075] 相比于如果将ISCZ设置在更靠近把手12的使用者握持部位的情况,当一个或多个ISCZ以靠近渐缩段16的方式被设置在把手12中时,球棒10在挥动期间对轴向对齐表现出更快的“迅速弹回”。 [0075] than if the ISCZ disposed closer to where the user gripping the handle portion 12, when one or more ISCZ way to approach a tapered section 16 is provided on the handle 12, the bat 10 during the wave of axially aligned showed faster "snapped back." 这种更快的迅速弹回通常被产生高速挥动速度的有经验打球者所喜爱。 This rapid rebound is usually faster to produce high-speed swing speed is experienced by those who love to play. 将ISCZ设置在更靠近把手12上的握持部位易于使有经验的打球者失去对棒的控制,这是由于棒10在球撞击时刻或临近该时刻的时候太慢而不能返回轴向位置。 The ISCZ disposed closer to the handle grip portion 12 is easy to make on the experienced golfer loses control rods, which is due to the time or the time in the ball striking rod 10 adjacent to the time too slow to return to the axial positions.

[0076] 但是,因为较少经验的打球者易于将棒“推动”穿过打击区,所以对于初学者来说, 可能优选地是将ISCZ以靠近使用者握持部位的方式定位在棒把手12中,并且因此不会导致棒10显著地“折弯”到轴向对齐状态之外。 [0076] However, since the less experienced golfer to easily stick "pushed" through the strike zone, so for beginners, the ISCZ may preferably be closer to the user so as to grip the handle portion of the rod 12 is positioned , and therefore the rod 10 does not cause significant "bend" beyond the axially-aligned state. 本领域技术人员将认识到,ISCZ在把手12 中的特定布置通常取决于余下的棒把手12的挠性、棒筒身14的重量、将来使用者的技能水平、以及把手12中所用的材料。 Those skilled in the art will recognize that, ISCZ particular disposed in the handle 12 generally depends on the remaining flexible rod handle 12, the weight of the rod 14 of the barrel, the future level of skill of the user, the handle 12 and the material used.

[0077] 图11-15示出了一些实施例,其中,在球棒10中包括一个或多个整体碰撞衰减(ISA)区域。 [0077] FIG 11-15 illustrates some embodiments, wherein in the ball bat 10 includes one or more integral crash attenuator (ISA) region. 参照图11,ISA区域130位于球棒10的过渡区或渐缩段16中。 Referring to FIG. 11, ISA region 130 is located in the transition zone 10 or tapered toe section 16. ISA区域130 (以及以下所述实施例中的其它ISA区域)包含一个或多个高衰减和/或低模量材料,这些材料在从进入ISA区域130的激波中消散或减弱振动能量方面是有效的。 ISA region 130 (as well as the other embodiments of the ISA region Embodiment) comprises one or more high attenuation and / or low modulus material, these materials are in vibrational energy dissipated or attenuate the shock wave from entering the ISA region 130 in Effective. 构成ISA区域130 的一种或多种材料优选地比纵向位于棒结构中的ISA区域130上方和/或下方的相邻材料具有低得多的纵向或轴向杨氏模量。 Young's modulus in the longitudinal or axial ISA region constituting material is preferably one or more ISA region 130 is located above the rod structure 130 and / or bottom of the adjacent material having much lower than longitudinal. 因此,假设是相对均勻的截面厚度,则ISA区域130比纵向位于ISA区域130上方和/或下方的材料(即图11中的筒身14和把手12的材料) 具有更低的轴向刚度(结构轴向刚度=轴向杨氏模量X材料的横截面模量)。 Thus, assuming a relatively uniform cross-sectional thickness, the ISA region 130 than the upper region 130 and ISA / or below the material (i.e., the barrel 11 of handle 12 and material 14) located in a lower longitudinal axial stiffness ( structure axial stiffness = Young's modulus of the axial cross-X section modulus material).

[0078] ISA区域130优选地由一种或多种材料制成,这些材料具有的轴向杨氏模量是纵向位于棒结构中的ISA区域130上方和/或下方的相邻材料的轴向杨氏模量的15-85%、或30-70 %、或40-60 %、或50 %。 [0078] ISA region 130 is preferably made of one or more materials, an axial Young's modulus of these materials are located in longitudinal and / ISA region axially above 130 bar structure or material adjacent the bottom of the Young's modulus of 15-85%, or 30-70%, or 40-60%, or 50%. 例如,ISA区域130可以由具有大约3_7ms i、或4_6ms i的轴向杨氏模量的材料制成,而棒结构的相邻区域可以具有大约8-12msi或IOmsi的轴向杨氏模量。 For example, ISA region 130 may be made of a material having approximately 3_7ms i, or 4_6ms i axial Young's modulus, and an adjacent area may have a bar structure or about 8-12msi IOmsi axial Young's modulus.

[0079] 如图15的表格所示,所给材料层片(表格中仅以示例方式示出了石墨和玻璃纤维类型的s玻璃)的轴向杨氏模量随着其相对于球棒10的纵轴135的方向而变化。 An axial Young's modulus [0079] The table shown in FIG. 15, given plies (shown in the table by way of example only and a glass fiber type graphite s glass) with respect to which the bat 10 changes the direction of the longitudinal axis 135. 因此,为ISA区域130而选择的特定材料可以根据棒结构内的材料层的方向而改变。 Thus, the particular material selected ISA region 130 may vary depending on the direction of the material layer within the rod structure.

[0080] 为了满足上述实例中规划的参数,例如,ISA区域130可以包括包含加固的s玻璃纤维的一个或多个复合层或层片,其中大体上每个层片均定向在相对于球棒的纵轴而言10· •至20· •的角度处(从而每个层片的轴向杨氏模量是大约4. 21-5. 87msi)。 [0080] In order to satisfy the above-described example planning parameters, e.g., ISA region 130 may include a reinforcement comprising a glass fiber s or more composite layers or plies, wherein each ply is oriented substantially with respect to bat respect to the longitudinal axis 10 · • 20 · • at an angle (such that the axial Young's modulus of each ply is about 4. 21-5. 87msi). 类似地,ISA区域130可以包括包含加固的石墨纤维的一个或多个复合层或层片,其中大体上每个层片定向在相对于球棒的纵轴而言25 · •至35 · ·的角度处(从而每个层片的轴向杨氏模量是大约4. 02-6. 47msi)。 Similarly, ISA region 130 may include or comprise a plurality of composite layers or plies of graphite fiber reinforced, wherein substantially each ply oriented relative to the longitudinal axis of the ball bat 35 to 25 · • · in angles (so that the axial Young's modulus of each ply is about 4. 02-6. 47msi).

[0081] 其它可能的ISA区域材料包括,但不限于,包含加固纤维的复合层或层片,所述纤维是芳族聚酰胺(例如Kevlar®、Spectra®、等等)、PB0 ( Zylon® )、UHMWPE (超高分子量聚乙烯),和/或在各个层片方向上具有相对较低轴向杨氏模量和/或其它具有高阻尼特性的任何其它合适的材料。 [0081] Other possible ISA region materials include, but are not limited to, the composite layers or plies comprising reinforcement fibers, the fibers are aramid (e.g. Kevlar®, Spectra®, etc.), PB0 (Zylon®) , the UHMWPE (ultra high molecular weight polyethylene), and / or have a relatively low axial directions on the respective plies Young's modulus and / or other any other suitable material having a high damping characteristic. 诸如弹性橡胶的粘弹性材料也可以用在ISA区域130中。 A viscoelastic material such as rubber elasticity can also be used in ISA region 130. ISA区域130优选地还包括加固树脂(诸如热固树脂、热固塑料、和/或注入树脂)、或任何其它合适的树脂。 ISA region 130 preferably further comprises any other appropriate reinforcing resin resins (such as thermosetting resins, thermosetting plastics and / or resin is injected), or.

[0082] 通过将ISA区域130设置在球棒10的过渡区或渐缩段16中,可以削弱棒结构中的振动能量,同时不会影响筒身的动力学性能。 [0082] provided by the ISA region 130 in the toe region 10 of the transition or tapered section 16, the vibration energy can weaken the structure of the rod, without affecting the performance of the kinetics of the barrel. 低模量、高阻尼的ISA层用作偏中心撞击导致的从筒身14朝向球棒10的把手12传播的激波的消散隔层。 Low modulus, ISA eccentric high damping layer serves to dissipate impact barrier shock propagating from the handle 12 toward the barrel 14 of the ball bat 10 results. ISA区域130削弱或吸收激波,从而基本上或完全防止了激波到达棒把手12和打球者的手部。 ISA region 130 absorb shock to weaken or to substantially or completely prevent the hand grip portion 12 and the shock wave reaches the bars the golfer. 因此,基本上降低或消除了刺痛。 Thus, substantially reducing or eliminating the irritation.

[0083] 参照图12,在另一实施例中,ISA区域140位于球棒10的其中把手12并入渐缩段16的区域中,从而ISA区域140同时位于球棒10的把手12和渐缩段16中。 [0083] Referring to FIG. 12, in another embodiment, the ISA region 140 is located where the handle 12 of the bat 10 is incorporated in the region of the tapered section 16, so that while the ISA region 140 is located in the handle 12 of the bat 10 and tapered 16 paragraph. 由于其相对低的横截面模量,使得将ISA区域140定位在该部分中是有利的,这有助于该部分的相对低的轴向刚度,从而有助于ISA区域140的振动运动消散进入ISA区域140中的激波能量。 Due to its relatively low cross-section modulus, so that the ISA region 140 is positioned in this section is advantageous, which contributes to a relatively low axial stiffness of this portion, thereby contributing to the vibrating motion of the ISA region 140 to dissipate into the shock energy of 140 ISA region.

[0084] 参照图13,在另一实施例中,ISA区域150形成为包括插入物155的夹层结构,该插入物由一种或多种高阻尼材料制成并由加固纤维复合材料的一个或多个层片包围。 [0084] Referring to FIG 13, in another embodiment, ISA region 150 is formed as a sandwich structure 155 comprising the insert, the insert is made of one or more high damping material is a composite material reinforced by fibers or surrounded by a plurality of plies. 插入物155优选地是粘弹或弹性橡胶、聚氨酯、和/或泡沫材料,或使振动能量有效衰减的任何其它适宜材料。 Insert 155 is preferably a viscoelastic or elastic rubber, polyurethane, and / or foam material, or the effective attenuation of vibration energy of any other suitable material. 在ISA区域150中包括这样的插入物155可以增加ISA区域150的效率和耐用性,特别是在包围ISA区域的纤维具有低压缩强度和/或弱应变能恢复性的情况下。 It includes an insert 155 may increase the efficiency and durability of the ISA region 150, in particular a low compressive strength and / or the case of weak strain energy recovery in the fiber region surrounding the ISA region 150 in the ISA. 夹层ISA区域150可以位于把手12、渐缩段16、和/或棒结构的任何其它适当的区域中。 Sandwich ISA region 150 may be located in the handle 12, the tapered section 16, and / or any other suitable region of the rod structure. 在图14中仅以示例的方式示出了夹层ISA区域150,其位于球棒10的其中把手12并入渐缩段16的区域中。 In the embodiment in FIG. 14 only shows an example of a sandwich ISA region 150, which is located where the bat handle 12 tapered region 10 is incorporated in section 16.

[0085] 参照图14,在另一实施例中,两个(或更多个)ISA区域160、170可以用来将棒筒身14的撞击部位与球棒10的把手12和端盖20相隔离。 [0085] Referring to FIG 14, in another embodiment, two (or more) regions 160 and 170 the ISA may be used to grip the rod portion and striking the bat barrel 10, 14 and 12 of the end cap 20 relative isolation. 球棒10的端盖20通常比相邻筒身部分的刚度大,从而端盖20可为棒筒身14的开口端提供充足的耐用性。 The end cap 20 of the bat 10 is generally larger than the rigidity of the shaft section adjacent to the end cap 20 can provide sufficient durability to the open end of the barrel 14 of the rod. 为了刚化棒筒身14的端部,通常的方法是锻造棒筒身的端部、轧制筒身的边缘,以形成完整或接近完整的盖子、和/或用聚氨酯或类似的半刚性材料填充筒身。 For stiffening the barrel end of the rod 14, the usual method is forged rod end of the barrel, the barrel rolled edge, to form a complete or nearly complete lid and / or polyurethane or similar semi-rigid material filled barrel.

[0086] 但是,端盖20的刚化可能增加球棒10的振动响应,同时使得筒身的充分运动不能有效地消散振动能量。 [0086] However, the stiffening cap 20 may be increased in response to the vibration ball bat 10, while allowing full movement of the barrel can not be efficiently dissipate the vibration energy. 通过将第一ISA区域170定位成邻近棒10的端盖20,以及将第二ISA区域160定位在棒10的渐缩段16 (或把手1¾处或附近,使得在棒10的撞击部位处弓I 起的振动与把手12和端盖20隔离,从而只有很少的或没有振动能量传播到棒把手12 (和打球者手部)或相对刚性的端盖20。因此,基本上降低或消除了刺痛。 ISA region 170 by the first end cap is positioned adjacent the rod 10 20, and the ISA region 160 is positioned in the second (or 1¾ handle at or near the tapered section 16 of the rod 10, such that the bow in the rod 10 at the impact site I played with the vibration isolating handle 12 and end cap 20, so that only little or no vibrational energy to the end cap a relatively rigid rod or handle 12 (and the golfer hand portion) 20. Thus, substantially reducing or eliminating the sting.

[0087] 在上述的任何ISA实施例中,所用的ISA区域可以占据单壁筒身设计中的棒壁的整个径向厚度(例如,图11-14所示)或仅占据该径向厚度的一部分。 [0087] In any of the above embodiments ISA, ISA region used may occupy the entire radial thickness of the wall of the rod of single-wall barrel design (e.g., as shown in FIGS. 11-14) or the radial thickness occupies only part. 在多壁筒身设计中, ISA区域可以仅包含在棒壁的一个壁中或包含在棒壁的两个或更多个的壁中。 In the design of multi-wall barrel, ISA regions may only comprise one wall or wall of the bar contained in the walls of two or more bars in the wall. 此外,用于多壁筒身中的任何ISA区域可以占据棒壁中的一个或多个壁径向厚度的全部或一部分。 In addition, any ISA region for multi-walled barrel may occupy all or a portion of a wall rod or a plurality of radial wall thickness. 虽然当一个或多个ISA区域占据整个径向壁厚度时激波通常将会被更好地削弱,但是一个或多个ISA区域可以占据径向壁厚度的任何合适的部分。 Although when one or more ISA regions occupy the entire radial wall thickness typically will be better shock impaired, one or more of any suitable ISA regions may occupy radially wall thickness.

[0088] 一个或多个ISA区域的结构层方向可以改变,以获得所需的振动衰减等级。 [0088] one or more structural layers directions ISA regions may be varied to obtain the desired vibration attenuation level. 图15 的表格示出了如何通过改变层片相对于球棒10的纵轴的方向来更改给定材料(作为实例示出了石墨和S玻璃)层片的轴向杨氏模量以及层片的轴向刚度。 Table 15 shows how the direction of the longitudinal axis of the ball bat 10 by changing the change given ply material (shown as an example of the S-glass and graphite) an axial Young's modulus plies and plies the axial stiffness. 通过以这种方式改变一个或多个ISA区域层片,可以制作ISA区域,以满足各种各样打球者的需求。 By changing one or more ISA regions plies in this manner, ISA regions may be made to the player's various needs. 例如,可以操控球棒10中一个或多个ISA区域的整个范围的轴向刚度,为经验少的打球者提供较大的弹性回弹,或者为经验多的打球者提供较小的弹性回弹。 For example, the ball bat 10 may be manipulated in one or more axial rigidity of the entire range of the area ISA, provide greater elastic rebound is less experienced golfers, or to provide less elastic resilient multi experienced golfers . ISA区域也可以位于球棒10的特定区域中,以在那些区域中提供增加的挠性。 ISA regions may be located in a specific region of the ball bat 10, to provide increased flexibility in those regions.

[0089] 图16-18针对棒性能的优化,该优化是通过在离开最有效击球点的至少一个筒身区域中增加径向柔度来实现的。 [0089] Figures 16-18 bar for performance optimizations that by increasing radial compliance in at least one region of the barrel away from the sweet spot to achieve. 在典型的现有单壁金属棒中,材料强度和各向同性行为已被限制到棒刚度可以沿棒的纵轴而改变的程度。 In a typical prior single-wall metal rods, the material strength and isotropic behavior has been restricted to the extent that the stiffness of the rod can vary along the longitudinal axis of the rod. 因为没有足够的材料强度,降低靠近筒身端部(端盖处或渐缩段处)的棒筒身的刚度通常降低了棒的耐用性。 Because there is insufficient material strength, reduced stiffness near the barrel end (end cap or tapered segments at) rod barrel typically decreases the durability of the rod. 但是,复合材料的各向异性强度使得棒设计者能够独立地改变峰值(hoop)和棒筒身沿棒纵轴的轴向刚度。 However, the anisotropic material such that the strength of the composite rod designer to independently varying the peak (Hoop) and the axial stiffness of the rod barrel along the longitudinal axis of the rod. 多壁复合棒可以提供比单壁设计甚至更大的在筒身刚度方面的降低,并因此通常是优选的。 Multi-wall composite rod may be provided over a single wall design even greater reduction in the stiffness of the barrel, and thus are generally preferred. 但是,使用以下技术也可以加强单壁筒身。 However, using the following techniques can also strengthen the single-walled barrel.

[0090] 众所周知,当撞击发生在棒筒身的最有效击球点以外时,典型球棒的性能会下降。 [0090] is well known, when the impact occurs outside the sweet spot of the barrel rod, a typical ball bat performance will decrease. 通常,离开球撞击棒的最有效击球点越远,球棒性能就越不优化。 Typically, the sweet spot is far away from the ball striking bar, the less bat performance optimization. 此外,众所周知,由棒的挥动所产生的转动惯量在棒的自由端处大于在棒的渐缩段处。 Further, it is known, the moment of inertia of the swing rod produced at the free end of the rod is greater than the tapered section of the rod. 这种转动惯量有助于棒的整体性能。 This rotational inertia contributes to the overall properties of the rod. 因此,在没有进行分散的薄片制作以及其它加强手段的情况下,筒身性能通常在球棒的区2中要优于区1中。 Thus, in the production of the sheet is not the case of dispersion strengthening and other means, usually in the performance of the bat barrel zone 2 region is better than 1 in.

[0091] 因此,为了在筒身整个长度上优化筒身的性能,必须改进棒筒身14的区2,特别是区1的性能。 [0091] Accordingly, in order to optimize performance over the entire barrel length of the barrel, the barrel must be improved rod region 214, particularly the performance of a region. 增加区1和区2的径向柔度,即减小径向刚度,是改进棒筒身14的这些区域的性能的一个方法。 Increase in Zones 1 and 2 of the radial compliance, i.e., reduce the radial stiffness, a method of improving the performance of the rod barrel 14 in these regions. 通过相对于区3而增加区1和区2中的径向柔度,使得棒筒身14的处于渐缩段与最有效击球点之间的区域以及处于自由端与最有效击球点之间的区域可以表现得更类似于棒筒身14的最有效击球点。 3 with respect to the region by an increase in Zones 1 and 2 radial flexibility, so that the rod 14 in the barrel region between the tapered section and the sweet spot and at the free end of the sweet spot area between can behave more like stick sweet spot of the barrel 14.

[0092] 图16是概念性地示出了棒筒身14的区1和区2中为在筒身整个长度上优化筒身性能(即,使得筒身14的区1和区2的性能更接近区3 (及最有效击球点)的性能)而要求的径向柔度量的曲线图。 [0092] FIG. 16 is a diagram conceptually illustrating the performance of the rod region 14 of the barrel 1 and the barrel region 2 in order to optimize performance over the entire length of the barrel (i.e., such that the barrel 14 of the region 1 and region 2 is more proximity region 3 (and the sweet spot) performance) and the required radial compliance graph metrics. 如图16所示,由于在区2中相对于区1发生了更大的转动惯量(如上所述),所以区1中比区2中需要更大的径向柔度,即更低的径向刚度。 16, since the zone 2 to zone 1 phase has a greater moment of inertia (as described above), the region 1 than in region 2 needs a greater radial compliance, i.e. a lower diameter stiffness.

[0093] 在一个示例性实施例中,为了优化棒筒身14的性能,即为了使所有的三个筒身区中的性能基本相同,通常将区1中的径向刚度制作成是区3中的径向刚度的5 %至75 %,并且通常将区2中的径向刚度制作成是区3中的径向刚度的10%至90%。 [0093] In one exemplary embodiment, in order to optimize the performance of the rod 14 of the barrel, i.e. for the performance of all three zones is substantially the same barrel, generally radial stiffness in Zone 1 is made into region 3 the radial stiffness of 5 to 75%, and generally in the radial stiffness in zone 2 is made into the radial stiffness zone 3 10-90%. 在一个优选实施例中,区3中的径向刚度被制作成大约是3000磅/英寸,区1中的径向刚度被制作成小于1000磅/英寸,而区2中的径向刚度被制作成小于2000磅/英寸,如下文详细所述。 In a preferred embodiment, the radial stiffness of the region 3 is made to be about 3,000 lbs / inch, the radial stiffness in Zone 1 is made to be less than 1000 lbs / inch, and the radial stiffness in Zone 2 is made smaller than 2000 lbs / inch, as detailed below.

[0094] 当然每个区域中的径向刚度可以高于或低于这些范围,并且不是每个区域均必须被制作成满足图16所示的柔度曲线。 [0094] Of course, the radial stiffness of each region may be higher or lower than these ranges, and each region must not be made to meet the compliance curve 16 shown in FIG. 虽然满足柔度曲线的棒筒身是理想优化的,但是棒筒身可以被设计成仅在一个区域、或两个区域、或所有三个区域中增加了(或减少了)径向柔度,并且可以将任何给定区域中的径向柔度更改成比上述示例性实施例中规划的更大或更小的程度。 While the flexibility to meet the ideal curve optimized rod barrel, but the barrel may be designed to stick only increased (or decreased) in a radial compliance regions, or both regions, or all three regions, and may be in any given region of the radial compliance of the degree of greater or lesser than the plan changed to exemplary embodiments.

[0095] 图17示出了根据一个实施例的筒身层的区1-3的至少一部分的示例性横截面。 [0095] FIG 17 illustrates an exemplary cross-sectional area at least a portion of a barrel according to an embodiment of the layer 1-3. 例如,筒身14可以包括任何适当数目的复合层、和/或其它材料的层,并可以通过一个或多个ISCZ被分成任何适当数目的壁。 For example, barrel 14 may comprise any suitable number of composite layer, and the layer and / or other materials, and may be divided into any suitable number of walls by one or more ISCZ. 可替换地,筒身14可以包括不具有ISCZ的一个单壁。 Alternatively, the barrel 14 may comprise a single wall without having the ISCZ. 而且,可以将一个或多个区分成两个或更多个壁,同时一个或多个其它的区可以仅包括单壁。 Furthermore, one or more regions may be divided into two or more walls, while one or more other regions may comprise only a single wall. 当然,所出现的任何ISCZ可以终结于任何点处或在筒身14的整个长度上(或者更长)延伸,并且不必终结于两个概念性区域相遇的位置。 Of course, any ISCZ may be occurring at any point or at the end of the extension (or more) over the entire length of the barrel 14, and need not terminate in two regions meet conceptual position. 实际上,任何ICSZ可以重叠两个或更多个区,并且可以终结于两个区之间或单个区内,如美国专利申请序列号10/903,493中详细所述。 In fact, any ICSZ may overlap two or more regions, and may terminate in a single zone or zones between the two, as described in U.S. Patent Application Serial No. 10 / 903,493 in detail.

[0096] 可以通过一种或多种方法在一个或多个筒身区域中实现增加的径向柔度或降低的径向刚度。 [0096] may be implemented to increase the radial flexibility or reduced radial stiffness in one or more barrel zone by one or more methods. 在一个实施例中,棒筒身14中的各个复合层或层片可以被定向在相对于球棒10的纵轴而言的不同角度处,以增加棒筒身14的一个或多个区域中的径向柔度。 In one embodiment, each of the rod barrel composite layers or plies 14 may be oriented at different angles relative to the longitudinal axis of the ball bat 10, to add one or more regions rod barrel 14 the radial compliance. 通常,层片被定向成越靠近球棒10的纵轴,则径向柔度增加及径向刚度降低得越多。 Typically, the ply is oriented closer to the longitudinal axis of the ball bat 10, to increase the radial flexibility and radial rigidity reduced the more. 因此,随着从棒的纵轴所测量的层片角度方向的增加,层片的径向柔度降低,即当层片被定向成与球棒10的纵轴成90度(例如,如图15的表格中所示)时,径向刚度最大。 Thus, as measured from the longitudinal axis of the rod in the angular direction of the ply, the radial compliance of the ply is lowered, i.e. when the ply is oriented with the longitudinal axis 90 of the ball bat 10 (e.g., FIG. As shown in table 15), the maximum radial stiffness.

[0097] 因此,例如,沿筒身14长度延伸的复合层片可以被定向成,相对于球棒纵轴而言的角度在区1中比在区2中要小,并且在区2中比在区3中要小,以优化该层片的柔度。 [0097] Thus, for example, the composite plies extending along the length of the barrel 14 may be oriented relative to the longitudinal axis of the bat perspective than in zone 1 zone 2 is smaller, and the ratio in zone 2 3 is smaller in the zone, to optimize the compliance of the ply. 例如,图17中的层1(仅为了方便示例,其被示出为相对于棒纵轴被定向成基本为零度)可以相对于棒的纵轴被定向成,在区1中是+/-10 · •,在区2中是+/-20 · •,而在区3中是+/-60· ·。 For example, in FIG. 17 1 layer (only an example for convenience, it is shown with respect to the longitudinal axis of the rod is oriented substantially zero degrees) with respect to the longitudinal axis of the rod is oriented, in the region of +/- 1 10 · •, in zone 2 is +/- 20 · •, while in zone 3 is +/- 60 · ·. 当然,这仅是无数多个可能的层方位组合中的一种。 Of course, this is only one of numerous possible orientations combination of a plurality of layers.

[0098] 在此实例中,区1中的层1的径向刚度小于区2中的,并且区2中的小于区3中的(假设层1由均勻的材料制成,并具有均勻的厚度,等等)。 [0098] In this example, the radial stiffness in Zone 1 layer 1 is smaller than in region 2, and region 2 is smaller than the area 3 (assuming a homogeneous layer 1 is made of a material having a uniform thickness and ,and many more). 因此,相对于区3而言,径向柔度在区2中增加了,并且在区1中径向柔度增加得甚至更多,以在区1和区2中更好地接近区3的性能(S卩,基本满足图16所示的柔度曲线)。 Thus, with respect to the zone 3, the increased radial compliance in the region 2, and in a radial compliance region have increased even more, in order to better access to zone 1 and zone 2 zone 3 performance (S Jie, basically meet the compliance curve illustrated in FIG. 16).

[0099] 通常,希望将棒筒身14作为一个整体来优化,虽然仅优化特定的区域也可能是需要的。 [0099] Generally, it is desirable to stick barrel 14 as a whole is optimized, while optimizing only to certain areas may be required. 因此,虽然通常可能要遵循的概念是在棒筒身14的需要增加柔度的区域中层片可以被定向在相对于棒10的纵轴而言的较小的角度处,但是每个独立的层片不必非以这样的方式定向,以改进整体的筒身柔度。 Thus, although the concept is usually possible to follow the middle region of increased flexibility of the sheet bar in the barrel 14 may need to be oriented at a smaller angle relative to the longitudinal axis of the rod 10, but each individual layer sheet in such a manner do not have non-oriented, in order to improve the overall flexibility of the barrel. 实际上,只要在需要增加径向柔度的筒身区域中层片相对于球棒10的纵轴而言的角度方位通常小于需要较小柔度或不需柔度的区域中的角度方位,则通常将会改进棒筒身14的相对的整体径向柔度(假设筒身层由均勻的材料制成,并具有均勻的厚度,等等)。 Indeed, as long as the middle region of the barrel is necessary to increase the radial compliance of the sheet with respect to the angular orientation of the longitudinal axis of the bat 10 in terms of flexibility is generally less than or requires a smaller angular orientation without the softness in the area, then It will generally improve the overall rod opposite barrel 14 of the radial compliance (assuming barrel layer is made of uniform material and having a uniform thickness, and the like).

[0100] 在另一实施例中,在筒身的一个或多个区域中的一个或多个筒壁的厚度可以相对于其它筒身区域而减小,以降低在减小厚度的区域中的径向刚度。 [0100] In another embodiment, one or more of the thickness of the cylindrical wall of the barrel in one or more regions of the barrel relative to the other regions may be reduced to decrease the area of ​​reduced thickness radial stiffness. 例如,在区1和/或区2 中的筒壁的厚度可以相对于区3中的对应的筒壁厚度而减小。 For example, the thickness of the tube wall in the 1 and / or Zone 2 may be reduced relative to the barrel wall thickness in the region corresponding to 3. 通过在那些区域中的一个或两个区域中减小筒壁的厚度,那些区域中的径向刚度可以相对于棒筒身14的区3中的径向刚度而降低。 In those regions by one or two regions of reduced thickness of the cylindrical wall, the radial stiffness in those regions relative to the radial stiffness of the barrel region 14 of the rod 3 is reduced.

[0101] 类似于上述的层方位实施例,筒壁厚度可以在区1中比在区2中减小更多的程度, 以使径向刚度在区1中比在区2中降低更多的程度(假设使用均勻的筒身材料、层方位,等等)。 [0101] Similar to the above embodiment of the orientation layer, the wall thickness of the cartridge can be reduced more in degree than in the zone 2 zone 1, so that the radial stiffness decreased in region 1 than in region 2 more degree (assuming a uniform barrel material used, orientation layer, etc.). 因此,区1和区2中的径向柔度可以根据图16所示的柔度曲线增加,以优化筒身性能。 Accordingly, the radial compliance in Zones 1 and 2 may compliance curve illustrated in FIG. 16 increased barrel to optimize performance.

[0102] 在另一实施例中,具有不同径向刚度特性的不同材料可以位于不同的筒身区域中,以优化整个筒身14的筒身刚度。 Different materials [0102] In another embodiment, having different radial stiffness characteristics may be located in different regions of the barrel in order to optimize the rigidity of the entire barrel 14 of the barrel. 例如,比位于棒筒身14的其它区域中的材料具有更低径向刚度(在给定方位处)的材料可以设置在筒身14的区1和/或区2的部分中(或如果希望的话,设置在区3的部分中),以相对于筒身14中的其它区域而降低那些区域中的径向刚度。 For example, other than the region of the barrel 14 in the rod material having a lower radial stiffness (at a given orientation) of the material may be provided in a portion 14 of the barrel zone 1 and / or zone 2 (or, if desired then, a portion is provided in the region 3), with respect to other regions of the barrel 14 and to reduce the radial stiffness in those areas. 如同上述的实施例,通常希望在区1中比在区2中降低径向刚度的程度更大。 As with the embodiment described above, it is generally desirable to reduce 2 in zone 1 in a region greater than the radial stiffness. 因此, 在预定的层方位处具有较低径向刚度的材料量优选地在棒筒身14的区1比在区2中多,以便根据图16所示的径向柔度曲线更好地优化棒筒身。 Therefore, a lower amount of radial stiffness material is preferably in a predetermined orientation in the layer region of the rod 1 than the barrel 14 in the multi-region 2 in order to better optimize the radial compliance in accordance with curve 16 shown in FIG. Flashlight stick.

[0103] 类似地,比位于棒筒身14的其它区域中的材料具有更高径向刚度(在给定方位处)的材料可以设置在筒身14的区3的部分中,以相对于筒身14的其它区域而增加该区域的径向刚度。 [0103] Similarly, other than the region of the barrel 14 in the rod material having a higher radial stiffness (at a given orientation) of the material may be disposed in the barrel portion 14 of the region 3 with respect to the cylinder other body regions 14 increases the radial stiffness of the region. 通常,这里构思的任何结构是,在希望增加径向柔度的区域中使用较低径向刚度的材料,和/或在希望较少径向柔度的区域中使用较高径向刚度的材料。 Typically, any structure is contemplated herein, to increase the radial compliance region of the material used in the lower radial stiffness is desired, and / or use of material in the region of high radial stiffness less desirable flexibility in the radial direction .

[0104] 在另一实施例中,可以使用上述的筒身优化方法的任何组合,以优化棒筒身14的性能。 [0104] In another embodiment, the barrel may be used to optimize any combination of the above methods, to optimize the performance of barrel 14 of the rod. 例如,区1和/或区2中的一层或多层可以被定向成相对于球棒10纵轴而言的角度比在区3中的更小,并且在区1和/或区2中的一个或多个筒壁的厚度可以比区3中的筒壁的厚度更小。 For example, one or more layers 2, regions 1 and / or zone may be oriented with respect to the perspective of the longitudinal axis of the bat 10 is smaller than that in the zone 3 and in zone 1 and / or zone 2 one or more of the thickness of the barrel wall may be smaller than the thickness of the barrel wall in zone 3. 此外,位于区1和/或区2的部分中的一种或多种材料可以比位于区3中的材料具有更低的径向刚度,和/或具有较高径向刚度的一种或多种材料可以位于区3中。 In addition, portions located in Zone 1 and / or 2 in the region of one or more materials may have a lower radial stiffness than the material located in zone 3, and / or having one or more higher radial stiffness materials may be located in zone 3. 可以使用这些特征的任何可能想到的组合,或用于增加棒的最有效击球点之外的径向柔度的任何其它方法,以优化筒身性能。 Any conceivable combination of these features can be used, or any other method than the radially sweet spot to increase the softness of the rod, to optimize the performance of the barrel.

[0105] 为了便于描述,通过任何上述的方法以及任何其它适当的方法而表现出增加的径向柔度的筒身区域在下文中将表示为“径向柔度区域”。 [0105] For ease of description, by any of the methods described above and any other suitable methods exhibits increased radial compliance of the barrel region indicated as "radial compliance region" hereinafter. 径向柔度区域也可包含在球棒10 的渐缩段和/或棒把手12中,以在那些区域中提供增加的径向柔度和挠曲度。 Radial compliance regions may also be included in the tapered section of the ball bat 10 and / or handle bar 12, to provide increased radial compliance in those regions and the degree of deflection.

[0106] 将一个或多个径向柔度区域定位在球棒10的渐缩段中,为偏离筒身的撞击提供了更大的棒变形。 [0106] The one or more radial compliance regions in the bat positioned in the tapered section 10 is provided a greater deformation of the rod is offset from the impact of the barrel. 通过在球棒10的渐缩段16中增加一个或多个径向柔度区域,使得当球撞击发生在渐缩段16时,通常改进了棒10的性能,这类似于如上所述的棒筒身14的区1 和区2中的改进。 By adding one or more radial compliance regions in the tapered section 16 of the ball bat 10, such that when the ball impact occurs when the tapered section 16, generally improves the performance of the rod 10, similar to the rod described above improvement in the barrel region 2 and region 14 1.

[0107] 将一个或多个径向/轴向柔度区域定位在棒把手12中,通常改进了棒10的“触感”,这是因为提供了更多数目的界面,用于通过阻尼来消散振动能量。 [0107] One or more radial / axial flexibility region is located in the handle bars 12, generally improves the "feel" of the rod 10, because a greater number of interfaces to provide, through the damping means for dissipating vibration energy. 棒把手12还以弯曲和剪切变形的形式储存和释放能量。 The handle bar 12 also stores and releases energy in the form of bending and shear deformation. 因此,基于加速度的应用(即,基于棒的挥动),借助于径向柔度区域的选择性布置,通过使把手12变形至更大程度可以实现更高的能量转移。 Thus, based on the application of the acceleration (i.e., based on the swinging bar), by means of radial compliance regions selectively arranged, by transferring the handle 12 can be deformed to a greater extent higher energy. 以与如上所述调节“动态耦合”的筒身14所用的方法非常相同的方法,可以对于特定打球者的挥棒类型而调节把手12。 The method described above to adjust the "dynamic coupling" of the barrel 14 with the very same manner, the handle 12 can be adjusted for a particular type of player's swing.

[0108] 实际上,一些打球者可能喜欢在棒把手12中靠近球棒10的渐缩段16的位置具有较高的径向刚度区域,即具有较低径向柔度的区域。 [0108] In fact, some golfers may prefer having a high radial rigidity region 12 at a position near the rod grip the bat 16 of the tapered section 10, i.e., a region having a lower degree of radial compliance. 在靠近渐缩段16的位置提供增加的径向刚度使得棒10在挥动期间比如果在该区域中提供较低径向刚度的情况可以更快地“迅速弹回”至轴向对齐位置。 Provide increased near the tapered section 16 in a position such that the radial stiffness of the rod 10 is provided than if a lower radial stiffness in this region may be more quickly "snapped back" to the axially aligned position during swinging. 产生高挥动速度的有经验的打球者通常喜欢这种较快的迅速弹回。 Generate high swing speeds experienced golfers generally prefer this faster snapped back. 因此,将径向柔度区域位在靠近渐缩段16的把手12中,易于使有经验的打球者失去对棒的控制,这是由于棒10在球撞击时刻或临近该时刻的时候太慢而不能返回轴向位置。 Thus, radial compliance regions in the position near the tapered section 16 of the handle 12, to make easy experienced golfer loses control rods, which is due to the time or the time in the ball striking rod 10 adjacent to the slow time the axial position can not return.

[0109] 但是,对于初学的打球者或产生较慢挥动速度的打球者,可能优选地是在靠近球棒10的渐缩段16设置径向柔度区域。 [0109] However, for the novice golfer playing or slower swing speeds to produce, it may be preferably in the tapered section 10 near the toe 16 of a radial compliance region. 技能较差的打球者易于将棒“推动”穿过打击区,因此不会导致棒10显著地“折弯”到轴向对齐状态之外。 Poor skill golfer easily to stick "pushed" through the strike zone, and therefore the rod 10 does not cause significant "bend" beyond the axially-aligned state. 此外,通常希望将径向柔度区域定位在更靠近使用者握持位置的棒把手12中,以改进挥动过程中的棒10的触感。 Furthermore, compliance is often desirable to regions radially positioned in a position closer to the user holding the handle rod 12, in order to improve the tactile sensation during the swing rod 10. 因此,本领域技术人员将认识到,径向柔度区域在棒把手12中的优化定位通常取决于余下的把手12 的挠性、棒筒身14的重量、将来使用者的技能水平、以及把手12中使用的材料。 Thus, those skilled in the art will recognize, optimization of the positioning of the radial compliance in the region of the handle bars 12 remaining generally depends on the flexibility of the handle 12, the weight of the rod 14 of the barrel, skill level of the user in the future, and a handle 12 materials used.

[0110] 因此,径向柔度区域可以包含在球棒10的筒身14、渐缩段16、和/或把手12中, 以改进球棒10的整体性能和触感。 [0110] Thus, radial compliance regions in the bat barrel 10 may comprise a 14, a tapered section 16, and / or handle 12 in order to improve overall performance and feel of the bat 10. 类似地,为了产生高挥动速度的打球者考虑,在无需增加径向柔度的区域中(诸如在棒筒身14的最有效击球点处或附近,和/或靠近渐缩段16 的把手12中)可以降低径向柔度。 Similarly, in order to generate high swing speeds to consider play, without increasing the radial compliance in the region (such as a barrel handle bar at or near the sweet spot, and / or near the tapered section 14 of 16 12) may reduce the radial compliance. 例如,可以希望在筒身14的特定区域中降低径向柔度, 以满足棒球协会安全标准或其它安全规则。 For example, it may be desirable to reduce the radial compliance in specific areas of the barrel 14, to meet baseball association safety standards or other security rules.

[0111] 图18示出了典型双壁棒筒身(图18的曲线图中的双壁筒身曲线与图2的曲线图中所示的双壁筒身曲线相同)与优化的棒筒身14的相对性能特性的曲线对比,其中如上所述,优化的棒筒身在棒筒身14的区1和区2中具有径向柔度区域。 [0111] FIG. 18 shows a typical double-walled barrel bar (a double-walled barrel same graph graph curve 18 in FIG. 2 in the double-wall barrel curve shown) and a rod barrel optimization comparing the relative performance characteristics of curve 14, which as described above, to optimize the rod barrel has a radial compliance regions in the barrel region 14 of the rod 1 and region 2. 如图18所示,通过增加棒筒身14的区1和区2中的径向柔度,与典型双壁棒相比,通常改进了在筒身14的整个长度上的性能。 18, by increasing the area of ​​the rod 1 and the barrel 14 of the radial compliance regions 2, compared to a typical double-walled rods, generally improves the performance over the entire length of the barrel 14.

[0112] 重要的是,任何径向柔度区域的终点不必特意发生在两个区相遇的位置。 [0112] Importantly, the end of any radial compliance region without making a special place in two regions meet position. 实际上, 径向柔度区域可以重叠,或位于多于一个的区中,并且这些区可以短于或长于附图中所示的区。 Indeed, radial compliance regions may overlap, or in more than one region, and these regions may be shorter or longer than the region shown in the drawings. 而且,可以给定更多或更少数目的区。 Moreover, given greater or lesser number of areas. 实际上,这些“区”仅用于示例的目的,并不提供任何类型的实际或理论上的隔断。 In fact, the "zone" for illustrative purposes only and does not provide any actual or theoretical partition type. 因此,根据无数的设计,径向柔度区域可以定位、定向、 和/或建立在棒筒身14中(以及渐缩段16和把手12中)的各种各样的位置处,以实现所需的筒身和整体球棒性能特性。 Thus, according to numerous design, radial compliance regions may be located, oriented, and / or create rods barrel 14 (and tapered section 16 and the handle 12) at a variety of positions, to achieve a Flashlight needed to bat and overall performance characteristics.

[0113] 为此,图16-18所示的实施例通常针对在位于筒身最有效击球点之外的至少一个筒身区域中具有增加的径向柔度的球棒,以优化棒的性能。 [0113] To this end, as shown in Figures 16-18 embodiment having a generally bat for increased radial compliance in at least one barrel region located outside the sweet spot of the barrel in order to optimize the rod performance. 此外,在一个实施例中,优选地, 在棒的渐缩段与最有效击球点之间的筒身区域中比筒身的最有效击球点与自由端之间的筒身区域中,将径向柔度增加至更大的程度,以在那些区域中补偿转动惯量的不同作用。 Further, in one embodiment, the area between the barrel Preferably, the sweet spot of the barrel than in the barrel region between the tapered section of the rod and the sweet spot and the free end, the increased radial compliance to a greater extent in those areas to compensate for the moment of inertia of the different roles. 但是,可以认识到,根据对于具体球棒的设计目标,可以在筒身的任何区域(和/或球棒的其它部分)中以任何适当的结构增加(或降低)径向柔度。 However, it will be appreciated that, according to the design goals for a particular ball bat, can (and / or other portions of the bat) increase in any region of the barrel in any suitable configuration (or decrease) the degree of radial compliance.

[0114] 图19-22针对包括受限层阻尼的球棒。 [0114] Figures 19-22 are directed to a constrained layer damping bat. 图20示出了棒筒身14的一个实施例的内部截面,该棒筒身包括结合进棒筒身14的复合层232内的一个或多个振动阻尼元件或阻尼器230。 FIG 20 shows a barrel 14 of inner rod section of one embodiment, the barrel comprises a rod with one or more vibration-damping element or damping layer within the composite rod into the barrel 14 of 232,230. 一个或多个阻尼器230可以由任何适宜的振动衰减和阻尼材料制成,即,比球棒中的邻近或周围材料具有更低轴向弹性模量的材料。 One or more dampers 230 may be any suitable attenuated by the vibration damping material and are made, i.e., the ratio of the bat around or adjacent to a material having a lower axial elastic modulus of the material is. 在一个实施例中,一个或多个阻尼器230具有的轴向弹性模量可以是球棒10中邻近或周围材料的轴向弹性模量的0. 01-50%, 或0. 02-25%、或0. 05-10%、或0. 10-5. 0%,或0. 50-2. 5%、或0. 75-1. 25%。 In one embodiment, the one or more dampers 230 having an axial modulus of elasticity may be 0. 01-50% bat or axially adjacent to the elastic modulus of the surrounding material 10, or 0. 02-25 %, 05-10%, or 0.05, or 0. 10-5. 0%, or 0. 50-2. 5%, or 0. 75-1. 25%. 但是,可以使用比球棒10中的邻近或周围材料具有更低弹性模量的任何材料。 However, any material having a lower modulus of elasticity than the surrounding material 10 adjacent or bat.

[0115] 在一个实施例中,一个或多个阻尼器230由一种或多种粘弹性和/或弹性材料制成,例如弹性橡胶、硅树脂、凝胶泡沫、或其它类似的材料。 [0115] In one embodiment, the one or more dampers 230 made from one or more viscoelastic and / or elastic material, such as elastic rubber, silicone, gel foam, or other similar materials. 可替换地或另外,阻尼器230可以由任何其它适宜的阻尼材料制成,包括但不限于PBO (聚苯并恶唑),UHMWPE (超高分子量聚乙烯,如Dyneema®)、玻璃纤维、dacron® (“聚对苯二甲酸乙二醇酯”,PET或PETE)、 尼龙® (聚酰胺)、certran®、Pentex®、Zylon®、Vectran®、和/或芳族聚酰胺,这些材料相对于球棒10中的邻近或周围材料在消散或以其它方式衰减振动能量方面是有效的。 Alternatively or in addition, the damper 230 may be made of any other suitable damping material, including but not limited to, PBO (polybenzoxazole), the UHMWPE (ultra high molecular weight polyethylene, such as Dyneema ®), glass fibers, Dacron ® ( "polyethylene terephthalate", PET or PETE), nylon ® (polyamide), certran®, Pentex®, Zylon®, Vectran®, and / or aromatic polyamide, with respect to these materials 10 adjacent the bat or dissipated in the surrounding material or otherwise attenuate the vibration energy is effective.

[0116] 因此,根据用来形成球棒10的结构层的一种或多种材料,在球棒10中可以使用各种各样的阻尼材料(相对于那些邻近或周围结构材料而言)。 [0116] Thus, according to one or more materials used to form the structural layer 10 of the bat, the bat 10 may be used in a wide variety of damping materials (relative to those neighboring or surrounding structural materials). 例如,软橡胶阻尼材料可以具有大约10,OOOpsi的轴向弹性模量,而诸如芳族聚酰胺的“阻尼”材料可以具有大约12,000,OOOpsi的轴向弹性模量。 For example, a soft rubber dampening material may have about 10, an axial elastic modulus of OOOpsi, such as aramid and "damping" material may have about 12,000, an axial elastic modulus of OOOpsi. 虽然芳族聚酰胺的阻尼效果显著地小于典型软橡胶材料, 但是在具有甚至更高轴向弹性模量的周围或邻近结构棒材料上,它还是具有明显的阻尼效果,并且它相对于较软材料可以提供增加的耐用性。 While aramid damping effect is significantly less than a typical soft rubber material, but having a rod structure surrounding or adjacent material even higher axial elastic modulus, it is a significant damping effect, and it is relatively soft with respect to material can provide increased durability. 因此,具有相对较高轴向弹性模量的材料(诸如芳族聚酰胺)可以作为有效的阻尼器而用在一些球棒结构中。 Thus, a relatively high axial elastic modulus of a material (such as aramid) may be used in some bat structure as an active damper.

[0117] 每个阻尼器230可以形成球棒10内的一个或多个复合层的部分,或者可以作为单独的层而被包含进来。 [0117] Each damper 230 may form part of one or more composite layers within bat 10, or may be included as a separate layer to come. 每个阻尼器230还可以选择性地被夹在邻近复合层之间,如图21A 所示。 Each damper 230 also may be selectively interposed between adjacent composite layer shown in Figure 21A. 每个阻尼器230优选地被结合、固定、或以其它方式被附着或熔合到球棒10的周围复合材料中。 Each damper 230 is preferably coupled, fixed, or otherwise attached or fused to the surrounding composite material in the ball bat 10 in other ways. 在球棒10的一端或两端处的和/或在邻近阻尼器230的一端或两端的位置处的复合材料也可被熔合或混合到一起,以在棒结构与阻尼器230之间提供连续的载荷路径。 In and / or adjacent to the damper composite material at the position of one or both ends 230 may also be fused or mixed together to provide a structure between the rod and the damper 230 continuously at one or both ends of the bat 10 load path.

[0118] 在图21A所示的实施例中,仅以示例的方式示出了阻尼器230,其大体位于筒壁的中间平面处,在该平面剪切应力最高。 [0118] FIG. 21A in the embodiment shown, by way of example illustrates a damper 230, which is substantially in the middle plane of the cylinder wall, in the plane of maximum shear stress. 可替换地或另外,一个或多个阻尼器230可以位于构成棒筒身14的一个或多个筒壁的径向厚度内的任何位置,或者球棒10的任何其它区域内的任何位置。 Alternatively or in addition, one or more dampers 230 may be located anywhere within constituting a radial thickness of the cylindrical wall 14 of a plurality of rods or barrel, or any other location within any region of the ball bat 10. 例如,图21B示出了阻尼器230位于筒壁的内部的实施例。 For example, FIG. 21B shows an embodiment of the cylindrical wall 230 is located inside the damper. 在此实施例中,复合材料的至少一个内层优选地将阻尼器230限定在筒身结构内,并且优选地该内层延伸超出阻尼器230的每一端至少一英寸或更多。 In this embodiment, the at least one inner layer of composite material is preferably the damper 230 is defined within the barrel structure, and preferably the inner layer extends beyond each end of the damper 230 is at least one inch or more. 在另一实施例中,另外或可替换地,一个或多个阻尼器230可以类似地定位在一个或多个筒壁的外部或其它的棒区域。 In another embodiment, additionally or alternatively, one or more dampers 230 may similarly be positioned outside the other rod or one or more regions of the barrel wall.

[0119] 图21C示出了多个阻尼器230串联定位在筒壁内部的单一层内。 [0119] FIG 21C illustrates a plurality of dampers 230 positioned in series inside a single layer tubular wall. 在另一实施例中, 另外或可替换地,多个阻尼器230可以并排地设置,即定位在球棒10的大体相同的纵向位置处且处于筒身14内的不同径向位置处或其它棒区域。 In another embodiment, additionally or alternatively, a plurality of dampers 230 may be disposed side by side, i.e. located at substantially the same longitudinal position in the ball bat 10 and at a different radial position within barrel 14 or other bar area. 如果球棒10包括多壁筒身14和/或一个或多个ISCZ,则阻尼器230可以位于一个或多个筒壁的任何适宜的位置处,包括位于相邻筒壁之间的平面上的位置和/或靠着ISCZ —侧或两侧的位置。 If the bat barrel 10 includes a plurality of walls 14 and / or one or more ISCZ, the damper 230 may be located at one or more of any suitable tubular wall position, including on a plane between adjacent tube wall position and / or against ISCZ - position side or both sides. 因此,一个或多个阻尼器230可以位于球棒10的筒身14、过渡区16、和/或把手12内的任何位置,以获得所需的响应,如下文进一步所述。 Accordingly, one or more dampers 230 may be located in the barrel 14 of the ball bat 10, transition zone 16, and / or handle any location within 12 to obtain the desired response, as described further below. [0120] 一个或多个阻尼器230每一个均可以具有任何适宜的长度和/或厚度。 [0120] One or more dampers 230 each may have any suitable length and / or thickness. 例如,阻尼器230的长度可以是0. 25-5. 00英寸(如果需要,可以更长),而且厚度可以是0. 004-0. 100 英寸(或任何其它适宜的厚度)。 For example, the length of the damper 230 may be 0. 25-5. 00 inches (if necessary, can be longer), and may have a thickness of 0. 004-0. 100 inches (or any other suitable thickness). 在一个实施例中,每个阻尼器具有0. 008-0. 020英寸的厚度。 In one embodiment, each damper having 0. 008-0. 020 inches in thickness. 虽然阻尼器230可以是任何可想到的尺寸,并且理论上可以延伸大约球棒10的整个长度,但是优选地是在一个或多个有计划的位置处结合一个或多个分散的小尺寸阻尼器,以选择性地衰减振动,同时不会显著地增加球棒10的重量或降低其耐用性。 While the dampers 230 may be of any conceivable size, and may extend the entire length of the theoretically bat of about 10, but preferably with one or more small size dispersion at the position of a damper or more planned to selectively attenuate the vibration, while not significantly increase the weight of the ball bat 10, or reduce the durability.

[0121] 图22示出了34英寸的球棒10的一个实施例,包括球棒10的主要振动腹点(anti-node)的位置。 [0121] FIG. 22 shows a 34-inch bat embodiment 10, comprising a main vibration antinode bat (anti-node) 10 in position. 腹点是振幅最大的驻波中的点。 Abdominal point is the maximum amplitude of the standing wave in the points. 因此,在碰撞条件下,球棒10的振动腹点位于球棒10中的最大挠曲度的区域处(特别是对于振动中的棒的振型而言)。 Thus, under crash conditions, bat vibration antinode 10 in the region of the maximum deflection of the ball bat 10 (particularly for the vibration modes in the terms of the rod). 这里所使用的振动腹点通常表示球棒10的弯曲和/或峰值模式的腹点。 Vibration antinode used herein generally represents bending antinodes and / or peak pattern bat 10. 一个或多个这些振动腹点的位置(本领域技术人员很容易确定)可以根据球棒10的整体尺寸和构成而改变。 One or more locations (those skilled in the art readily ascertained) antinode these vibrations can vary according to the overall size of the ball bat 10 and configuration. 因此,仅以示例的方式在图22中示出了特定的腹点位置。 Thus, merely by way of example in FIG. 22 shows a specific antinode position.

[0122] 在一个实施例中,一个或多个振动阻尼器230位于球棒10中的一个或多个振动腹点处,并选择性地基本集中在这些振动腹点附近,以降低偏中心撞击在那些位置处所激发的振动的振幅。 [0122] In one embodiment, one or more vibration dampers 230 in the ball bat 10 located at one or more vibration antinode, and selectively concentrated in the vicinity of the antinode of vibration, in order to reduce the impact decentration in those positions premises amplitude of vibration excitation. 可替换地,由于挠曲度在接近腹点的棒区域处也是相对较高的,所以一个或多个阻尼器230可以定位成邻近或基本接近一个或多个振动腹点。 Alternatively, since the deflection of the rod at a region near the antinode it is relatively high, so that the one or more dampers 230 may be positioned adjacent to or substantially close to one or more vibration antinode. 这里所用的用来描述阻尼器位置的术语和词汇,诸如“基本在...处”或“在...处或附近”通常表示的意义是,阻尼器可以理想地直接位于腹点位置处,但阻尼器也可以可替换或附加地位于腹点附近,以产生阻尼效果。 Is used to describe the position of the damper terms and words used herein such as "substantially at ..." or "... at or near the" meaning generally indicates that the damper may be located directly over the location at antinodes , but the damper may alternatively or additionally be located near an antinode in order to produce a damping effect. 因此,这样的语言旨在表示阻尼器可以直接位于腹点处或非常接近腹点。 Consequently, such language is intended to represent a damper can be located directly at or very close to the ventral abdominal point point.

[0123] 通过吸收大量的剪切应变能并以热能形式将其消散到环境中,一个或多个阻尼器230降低了碰撞反作用力和模态振动的振幅。 [0123] by absorbing a large amount of energy and shear strain in the form of heat to dissipate into the environment, or a plurality of dampers 230 reduces the amplitude of the collision reaction force and modal vibration. 例如,由粘弹性材料制成的阻尼器230以比典型弹性材料低的速度(由于滞后作用)消散能量,使得碰撞能量的消散发生得相对较慢,这导致了初始碰撞脉冲的高阻尼。 For example, the damper is made of a viscoelastic material 230 at a speed ratio of the elastic material is typically low (due to hysteresis) dissipate energy, so that the impact energy dissipation occurs relatively slowly, which results in high initial impact damping pulse.

[0124] 阻尼器230的一个优选位置在球棒10的第一弯曲模式(即基波)的腹点处或其附近,在图22中以“1”表示。 A preferred position [0124] of the damper 230 at or near an antinode bat first bending mode (i.e., fundamental wave) 10 in FIG. 22 to "1". 第一弯曲模式的腹点在主要模式的全部腹点中表现出最大的变形和最高的应变能。 Antinodes of the first bending mode exhibited the highest maximum deformation and strain energy in the antinodes of all the main mode. 因此,通过将一个或多个阻尼器230定位在第一弯曲模式的腹点处或其附近,即在图22中所示的距离球棒10的盖端大约19-21英寸处,使得由偏中心撞击导致的大量振动能量可以被消散或以其它方式被衰减。 Thus, by applying one or more dampers 230 is positioned at or near the antinode of the first bending mode, i.e. the distance 22 in FIG toe cap end 10 about 19-21 inches, so that the biasing a large number of vibrational energy leads to the center of the impact is dissipated or may otherwise be attenuated.

[0125] 一个或多个阻尼器230也可以位于分别由图22中的数字“2”和“3”表示的球棒10的第二和/或第三弯曲模式的腹点处或其附近(其不会表现出和第一弯曲模式的腹点一样大的变形,但仍有助于振动效果),以抑制第二和/或第三弯曲模式。 [0125] One or more points at or near an antinode damper 230 may be located separately from the bat 22 in FIG. "2" and "3" of the second and / or third bending modes 10 ( it does not exhibit a first bending mode and antinodes as large deformations, but still contribute to the vibration effect) to inhibit the second and / or third bending modes. 为了抑制图22所示的球棒10的第二弯曲模式,例如,可以将一个或多个阻尼器230定位在距离球棒10的盖端大约8至10英寸、和/或沈至观英寸处。 In order to suppress the bat 22 shown in FIG. 10 of the second bending mode, for example, one or more dampers 230 is positioned at about 8 to 10 inches, and / or sink to the concept inches from the cap end of the ball bat 10 .

[0126] 在另一实施例中,阻尼器230附加地或可替换地定位在球棒10的由图22中的字母“A”表示的基本或第一峰值模式的腹点处或其附近。 [0126] embodiment, the damper 230 may additionally or alternatively be positioned substantially at or near or at an antinode of the first peak pattern of letters 10 of FIG. 22 bat "A" represents In another embodiment. 因为该腹点(其位于图22所示的距离球棒10的盖端大约4-8英寸处)基本在COP与第一和第二谐波弯曲节点(harmonic bending node)交叉处(即在球棒的“最有效击球点”处),所以在该位置处即使发生振动, 振动也是最小的。 Because the antinodes (located as shown in FIG. 22 from the toe end of the cap 10 at approximately 4-8 inches) COP substantially at the first and second harmonic curved intersection node (harmonic bending node) (i.e., the ball stick "sweet spot" at a), even when the vibration occurs at this position, the vibration is minimal. 因此,(如果有振动的话)在该位置处仅需要最少量的振动衰减来防止刺痛。 Thus, (if it vibration) at that location requires only a minimum amount of vibration damping to prevent irritation. 但是,通过在该“最有效击球点”处或其附近增加一个或多个阻尼器230,通常增加了最有效击球点的感觉尺寸,对于击球手提供了改善的触感。 However, by adding one or more dampers at or near the "sweet spot" 230, generally increases the feeling of the sweet spot size, provide for improved batter touch.

[0127] 多个阻尼器230可以位于整个棒结构中的任何组合的腹点处或其附近,以使球棒10中的振动最小。 [0127] a plurality of dampers 230 may be located at or near an antinode any combination of the rod structure overall, to minimize vibrations in the ball bat 10. 每个阻尼器230优选地相对于其它阻尼器230是独立的和不连续的,并且主要位于单个腹点处或附近。 Preferably, each damper 230 relative to the other of the damper 230 is separate and discontinuous, and is mainly located at or near a single antinode. 但是可以想到的是,一个或多个独立的阻尼器230可以重叠两个或更多个腹点。 It is conceivable that one or more independent dampers 230 may overlap two or more antinodes.

[0128] 例如,单个阻尼器230可以被定位成重叠位于球棒过渡区(即,距离图22所示的球棒10的盖端大约19-22英寸处)中的第一弯曲模式的腹点1和第三弯曲模式的腹点3。 Antinodes [0128] For example, a single damper 230 may be positioned to overlap the transition zone is located in the toe (i.e., the distance 22 shown in FIG bat end cover 10 about 19-22 inches) in the first bending mode 1 and the anti-node of the third bending mode 3. 但是,为了使棒结构的整体重量最小并保持足够的耐用性,通常优选地是,基本上每个阻尼器230均是独立的并有计划地定位在单个腹点处或其附近。 However, in order to minimize the overall weight of the bar structure and maintain sufficient durability, it is generally preferred that each of the dampers 230 are substantially independent and planned individual positioned at or near an antinode. 如上所述,多个阻尼器可以并排地(即不同径向位置)位于给定腹点处或其附近。 As described above, a plurality of dampers may be arranged side by side (i.e. different radial positions) is located at or near to a given antinode.

[0129] 图23和图M针对包含一个或多个集中屈曲区域的球棒。 [0129] Figures 23 and M comprises one or more centralized for turning area bat. 图23示出了包含集中屈曲区域330的球棒10的一个实施例。 Figure 23 shows a flex region 330 bat comprising a concentrated Example 10. 集中屈曲区域330包括径向内部区域331和径向部外区域333,该径向内部区域包含一种或多种结构复合材料(如上所述的材料),该径向外部区域包含一种或多种“非结构”材料,该“非结构”材料具有比球棒10中的邻近结构复合材料更低的轴向弹性模量。 Concentrated buckling region 330 includes a radially inner portion and a radially outer region 331 region 333, the radially inner region comprises one or more structural composite (material as described above), which comprises one or more radially outer region kind of "non-structural" materials, the "non-structural" than the adjacent material having a lower structure 10 bat axial elastic modulus of the composite material. 集中屈曲区域330优选地主要或全部位于球棒的过渡区16中, 但其可以可替换地或附加地部分或全部位于球棒10的把手12和/或筒身14中。 Buckling concentration region 330 is preferably predominantly or entirely located in the transition region of the ball bat 16, but may alternatively or additionally be partially or totally in the handle 12 of the bat 10 and / or the barrel 14. 而且,在球棒10中可以包含一个以上的集中屈曲区域330。 Further, in the ball bat 10 may include one or more centralized flex region 330.

[0130] 集中屈曲区域330的结构性径向内部区域331可以与球棒10中的邻近结构材料335相连续,或者可以是与所限定的起始和/或结尾位置相分离的区域。 [0130] Buckling concentrated area 331 radially inner structural region 330 may be continuous with the adjacent structural material 335 in the ball bat 10, or may start and / or end position of the separate defined region. 径向内部区域331 的厚度可以基本等于邻近区域中的结构材料或层335的厚度,该径向内部区域的厚度覆盖(包括)贯穿把手、筒身、和/或过渡段(即,该结构“管”在整个球棒10上可以具有相对均勻的厚度),或者径向内部区域331的厚度相对于球棒10中的一个或多个其它结构区域可以改变。 The thickness of the radially inner region 331 may be substantially equal to the thickness of the structural material or layer region 335 adjacent to the radially inner region of the thickness of the cover (including) through a handle, a body, and / or transition section (i.e., the structure " tube "over the entire ball bat 10 may have a relatively uniform thickness), or the radial thickness of the inner region 331 of the bat relative to one or more other structural regions 10 may vary.

[0131] 通过包含“锯齿状的”集中屈曲区域330,径向内部区域331中的结构层或材料或结构“管”的外径和内径相对于球棒10中的邻近区域而减小。 [0131] concentrated buckling region 330, 331 in the radially inner region layer structure or a structural material or "tube" outer and inner diameters with respect to adjacent regions of the bat 10 is reduced by the inclusion of "jagged." 在球棒10的给定纵向位置处的材料区域的结构性轴向弯曲刚度(El)是材料区域的外径D。 Structural axial bending stiffness (El) the toe region of material at a given longitudinal position of the outer diameter 10 of the material region D. 、材料厚度(D。-Di)、和材料轴向弹性模量E的函数,遵循以下公式: The material thickness (D.-Di), and an axial modulus of elasticity E of the material function, the following equation:

[0133] 附图中,参考符号D。 [0133] In the drawings, reference symbol D. 、D。 , D. '、Di、和Di'表示球棒10中的测量相应直径处的位置。 ', Di, and Di' representation bat 10 measures the diameter at the corresponding positions. 例如,D。 For example, D. 表示测量球棒10的外径处的位置。 It represents a measuring position at the outer diameter 10 of the ball bat. Di表示在测量除集中屈曲区域330之外的任何区域处测量球棒10的壁或管的内径处的位置。 Di represents an inner diameter at the measurement position or toe wall of the tube 10 in a region at any measurement other than the concentrated area 330 of flexion. 因此,D0和Di通常在把手12、过渡段16、和/ 或筒身14之间和/或内部变化。 Thus, D0 and Di typically handle 12, 16, and / or and / or internal changes between the barrel 14 section transition. D。 D. '和Di'表示球棒10中的分别测量集中屈曲区域330 的径向内部区域331的外径和内径处的位置。 'And Di' are represented by the toe 10 in flexion position measurement set 331 at the outer and inner diameters of the radially inner region 330 of the region.

[0134] 通过降低集中屈曲区域330的径向内部区域331中的结构材料的外径D。 [0134] By reducing the outer diameter of the structural material concentration region buckling radially inner area 331 of 330 D. ',使得在该区域处的结构“管”的轴向刚度相对于球棒10中的邻近区域而显著降低。 ', So that the stiffness of the structure in the axial region at the "tube" with respect to adjacent regions of the bat 10 is significantly reduced. 因此,集中屈曲区域330通常与球棒10的“反冲点”相一致。 Thus, buckling concentration region 330 generally consistent with the bat "kick point" 10. 反冲点表示由棒10的转动期间发生的惯性导致的球棒10中的最大曲率点。 It represents a point of maximum curvature point of recoil of the inertia generated by the bat 10 during rotation of the rod 10 caused. [0135] 对于集中屈曲区域330的一个可能的位置是在过渡段16中,并接近球棒10的主要基本振动腹点。 [0135] For a centralized location may be a flex region 330 in the transition section 16, and substantially close to the main vibration antinode ball bat 10. 通常,该位置处于或接近把手12的端部,且正好位于棒外径(D。)刚刚开始增加的地方。 Typically, this position is at or near an end portion of the handle 12, and is located just outside diameter of the rod (D.) place just starts to increase. 该区域在挥棒期间经历最高轴向变形,从而可以通过利用棒10的在此特定区域发生弯曲的这种自然趋势而转换至打球者特定的挥动样式。 The region subjected to the highest axial deformation during the swing, so that this natural tendency of bending is converted to a golfer swinging a specific pattern can occur in this particular region by using the rod 10. 此位置的一些优点在于, 典型球棒10的外径(D。)在此位置不至于大到使截面刚度显著增加的程度,也不至于在棒挥动加速导致棒折弯的期间在此部分之外具有足够大的筒身质量用于惯性载荷。 Some of the advantages of this is that the position of the outer diameter of (D.) typical ball bat 10 at this location will not be so large that a significant increase in cross-sectional extent of rigidity, will not cause acceleration of the rod during the waving rod bent in this section of an outer barrel having a sufficiently large inertial mass load. 此外,在此位置上通常很难出现球碰撞,使得此位置上形成的棒轴向屈曲不应该显著地负面影响棒的耐用性。 Further, this position is often difficult ball collision occurs, so that the position of this rod is formed axially flexion should not be significantly adversely affect the durability of the rod.

[0136] 对于诸如铝(E = 106psi)的特殊均质材料,例如,具有1. 50英寸外径D。 [0136] For such as aluminum (E = 106psi) special homogeneous material, e.g., having an outer diameter of 1.50 inches D. 和0. 10 英寸厚度(Dtj-Di)的壁或结构管的弯曲刚度是具有1. 15英寸外径D。 And a wall thickness of 0.10 inches (Dtj-Di) of the bending stiffness or structural tube having an outer diameter of 1.15 inches D. '的相同厚度壁或管的大约235% (即刚度是2.35倍)。 'Is the same as a wall thickness of about 235% or tube (i.e., the stiffness is 2.35 times). 因此,相对于1.15英寸直径的管,需要大约2. 35倍的载荷来将1. 50英寸直径的管折弯至相同的变形程度。 Thus, with respect to the tube diameter 1.15 inches, about 2.35 times the need to load the 1.50 inches diameter pipe bent to the same degree of deformation. 以另一方式,对于固定能量的挥动,球棒10的1. 15英寸直径的结构区域将以1. 50英寸直径结构区域的大约235%的势能来偏转或反弹(实际的差别将根据集中屈曲区域330的径向外部区域333的材料特性来变化)。 In another embodiment, for about 235% of the potential energy will be 1.50 inches in diameter region structure area structure waving fixed energy, the bat 10 is 1.15 inches in diameter to rebound or deflection (difference between the actual flexion according concentrated area 330 radially outer region to change the material properties of 333).

[0137] 因此,通过使集中屈曲区域330的径向内部区域331中的结构材料的局部直径(D0')进行微小改变,球棒10的局部轴向刚度和挠度可以显著地降低或另外地发生变化。 [0137] Thus, by making a minor change of the local concentration buckling radially inner diameter area of ​​the structural material 331 in the area 330 (D0 '), local axial stiffness and deflection ball bat 10 may significantly reduce the occurrence or otherwise Variety. 为达到结构材料中的这些直径变化的所期望效果,集中屈曲区域330的径向外部区域333 优选地由具有比球棒10中的一种或多种邻近结构材料335的轴向弹性模量更低的轴向弹性模量的一种或多种材料构成。 In order to achieve the desired effect of these structural materials of varying diameter, the region 330 concentration buckling radially outer region 333 is preferably greater than the axial modulus of elasticity of one kind or more of the bat 10 adjacent the structural material 335 having low modulus of elasticity in the axial direction of one or more materials.

[0138] 在这里以“阻尼材料”表示的这些低轴向弹性模量材料可以包括一种或多种粘弹性和/或弹性材料,诸如弹性橡胶、硅树脂、凝胶泡沫、或具有相对较低轴向弹性模量的其它类似的材料。 [0138] These low modulus of elasticity in the axial herein to "damping material" means may comprise one or more viscoelastic and / or elastic material such as elastic rubber, silicone, gel foam, or with a relatively other similar materials of low axial elasticity modulus. 具有比球棒中的邻近结构材料335更低弹性模量的任何其它材料可以可替换地或附加地用在径向外部区域333中,这种材料包括但不限于PBO(聚苯并恶唑)、UHMWPE (超高分子量聚乙烯,如Dyneema® ),玻璃纤维、dacron® ( “聚对苯二甲酸乙二醇酯”,PET或PETE)、尼龙® (聚酰胺)、 certran®、Pentex®、Zylon®、Vectran®、如/ 或芳族聚酰胺。 Bat material having adjacent structure 335 in any other lower modulus of elasticity material may alternatively or additionally be used in the radially outer region 333, the ratio of such materials include but are not limited to, PBO (polybenzoxazole) , the UHMWPE (ultra high molecular weight polyethylene, such as Dyneema ®), glass fibers, dacron® ( "polyethylene terephthalate", PET or PETE), nylon ® (polyamide), certran®, Pentex®, Zylon®, Vectran®, such as / or aramid.

[0139] 因此,根据用来形成球棒10的结构层335的一种或多种材料,在集中屈曲区域330 的径向外部区域333中可以使用各种各样的阻尼材料(相对于邻近或周围结构材料335而言)。 [0139] Thus, according to the material used to form one or more structural layers of the ball bat 10 335, in the radially outer region of concentrated flex region 333,330 may be used in a wide variety of damping material (or with respect to adjacent 335 in terms of material surrounding structures). 例如,软橡胶阻尼材料可以具有大约10,OOOpsi的轴向弹性模量,而诸如芳族聚酰胺的“阻尼”材料可以具有大约12,000,OOOpsi的轴向弹性模量。 For example, a soft rubber dampening material may have about 10, an axial elastic modulus of OOOpsi, such as aramid and "damping" material may have about 12,000, an axial elastic modulus of OOOpsi. 虽然芳族聚酰胺的轴向弹性模量显著大于典型软橡胶材料的轴向弹性模量,但是对于具有甚至更高轴向弹性模量的周围或邻近结构棒材料,芳族聚酰胺还是可以具有明显的阻尼作用,并且它相对于较软的材料可以提供增加的耐用性。 Although axial elastic modulus aramid is significantly greater than the axial modulus of elasticity of a typical soft rubber material, but for having a rod material surrounding or adjacent structure even higher axial elastic modulus, aramid or may have significant damping effect, and it is relative to softer materials may provide increased durability. 因此,在一些球棒结构中,诸如芳族聚酰胺的具有相对较高轴向弹性模量的材料可以用作有效的阻尼器。 Thus, in some ball bat constructions, such as an aromatic polyamide material having a relatively high axial modulus of elasticity can be used as an effective damper.

[0140] 图M示出了集中屈曲区域330的一个可能的结构,虽然可以可替换地使用适于在集中屈曲区域330中提供降低的轴向刚度的任何其它形状或结构。 [0140] FIG M shows one possible configuration concentrated flex region 330, may alternatively be used although any other shape or configuration adapted to provide a reduced axial stiffness in flexion concentrated area 330. 集中屈曲区域330的径向外部区域333优选地具有大约0. 060-0. 250英寸或0. 080-0. 120英寸的深度(大约等于D0-D0')。 Buckling concentration region 333 radially outer region 330 preferably has about 0. 060-0. 080-0 0. 250 inches or 120 inches depth (approximately equal to D0-D0 '). 可替换地,可以使用任何其它的深度。 Alternatively, any other depth. 如果在球棒10中(例如在多壁棒中)包含了ISCZ或类似区域,则径向外部区域333可以具有延伸至ISCZ (或穿过ISCZ中的开口)的深度。 If the ball bat 10 (e.g., in a multi-walled rod) or the like comprising a ISCZ region, the radially outer region 333 may have a depth extending to the ISCZ (or through an opening in the ISCZ) a.

[0141] 径向外部区域333的基部优选地具有0. 20-1. 50英寸或0. 40-0. 80英寸的长度, 并且径向外部区域333的外表面(对应于球棒10的外表面)优选地具有大约0. 25-2. 50 英寸或0. 50-1. 50英寸的长度。 Preferably, the outer base [0141] 333 having a radially outer region of 0. 20-1. 40-0 0. 50 inches or 80 inches in length, and the outer surface of the radially outer region 333 (corresponding to the bat 10 surface) preferably has about 0. 25-2. 50-1 0. 50 inches or 50 inches in length. 径向外部区域333可以具有任何其它适宜的尺寸,并且可以具有或不具有渐缩端部区域334(例如,如图M所示)。 A radially outer region 333 may have any other suitable size, and may or may not have a tapered end region 334 (e.g., as shown in FIG M).

[0142] 在一个实施例中,径向外部区域333的深度是径向内部区域331厚度的60%-150%或80%-120%。 [0142] In one embodiment, the depth of the radially outer region 333 is 60% -150% or 80% -120% of the thickness of the radially inner region 331. 附加地或可替换地,径向内部区域331的外径D。 Additionally or alternatively, the outer diameter of the radially inner region 331 D. '是球棒10中的邻近纵向区域的外径D。 'It is the outer diameter of the longitudinal area adjacent to the bat 10 D. 的60% -95%或70% -85%。 60% -95% or 70% -85%. 附加地或可替换地,集中屈曲区域330变成具有的轴向刚度是球棒的邻近纵向区域的轴向刚度的10% -90%、或30% -70%, 或40% -60%。 Additionally or alternatively, a flex region 330 becomes concentrated with the axial stiffness of 10% to 90% of the axial stiffness of longitudinally neighboring regions in the ball bat, or 30% -70%, or 40% -60%. 此降低的轴向刚度可能是径向外部区域333中的材料比球棒10中的邻近区域具有更低轴向弹性模量和/或是径向内部区域331比球棒10中的邻近纵向区域具有更小外径D。 This may be reduced axial stiffness radially outer region 333 of a material having a lower axial elastic modulus and / or the radially inner area 331 than in the ball bat 10 than adjacent longitudinal region adjacent to the toe region 10 having a smaller outer diameter D. '和/或更小厚度(D。' -Di')的结果。 'And / or smaller thickness (D.' result-Di ') of. 根据给出的棒设计的规定,这些相对百分比中的一个或多个可以变化超出这里所述的界限。 Under given bar design, a relatively these percentages can vary beyond the limits or more herein.

[0143] 一个或多个集中屈曲区域330的位置、形状、和结构可以基于给出的球棒10的结构要求而变化。 [0143] or a more centralized location areas 330 of flexion, the shape, structure, and may vary based on the structural requirements given by the bat 10. 通过将集中屈曲区域330定位在过渡段16中,例如,可以增加棒挠性,并且可以从棒结构中使振动能量衰减,从而增加了筒身的动力学性能。 By centralizing the flex region 330 positioned at the transition section 16, for example, you can increase the flexibility of the rod, and may attenuate the vibration energy manipulation rod structure, thereby increasing the kinetic performance of the barrel. 集中屈曲区域330的轴向刚度和位置可以转变成提供用于改变棒击类型(如推击或弹回类型)的特殊反冲。 Axial stiffness and buckling centralized location area 330 may be transformed into special recoil for changing clubbed type (e.g., hitting or pushing spring back type). 例如, 集中屈曲区域330可以在典型棒球球棒中定位成更靠近筒身14,或在典型快速投掷垒球球棒中定位成更靠近把手12。 For example, area 330 may be positioned buckling concentrated closer to the barrel 14, or handle 12 is positioned closer to the typical fast throwing softball bat in a baseball bat typical.

[0144] 通常,集中屈曲区域330可以在渐缩段16中定位成朝向筒身14,以在挥动期间提供增加的“迅速弹回”,然而它可在渐缩段16中定位成朝向把手12,为在挥动期间易于“推动”棒的打球者提供较小的迅速弹回。 [0144] Generally, buckling focus area 330 may be positioned in the tapered section 16 toward the barrel 14 to provide increased "snapped back" during wave, but it may be positioned in the tapered section 16 toward the handle 12 , provide a smaller snapped back as during the wave easy to "push" the golfer's bar. 因此,根据给出的棒设计的要求,一个或多个集中屈曲区域330可以位于棒结构内的任何位置。 Thus, according to the design requirements given rod, one or more centralized buckling area 330 may be located anywhere within the rod structure.

[0145] 这里所述的各种球棒实施例可以以任何适宜的方式构造。 [0145] Here the various embodiments may be configured bat in any suitable manner. 在一个实施例中,通过将棒10的各层卷到芯棒(mandrel)或具有所需棒形状的类似结构上而构造球棒10。 In one embodiment, the layers by the roll 10 to the mandrel rod (Mandrel) or similar structure having the desired shape of a rod 10 constructed bat. 任何ISCZ、ISA区域、径向柔度区域、阻尼元件、和/或集中屈曲区域优选地有计划地建立、布置、 定位、和/或定向,如上面实施例所述。 Any ISCZ, ISA region, the radial compliance region, the damping element and / or centralized planned buckling region is preferably established, arranged, positioned, and / or orientation, as described in the above embodiment.

[0146] 材料层的端部优选地是彼此“编织(clocked) ”或胶印(offset)的,从而在固化之前它们不会全都终结于相同位置。 [0146] Preferably, the end portion of the material layer being "braided (clocked)" or offset (offset) so that they do not cure before all end at the same position. 此外,如果使用变化的层方位和/或壁厚度,则层可以交错、蓬松(feather)、或以其它方式成角度或被操作,以形成所需的棒形状。 Furthermore, if layers of varying orientation and / or wall thickness, the layers may be staggered, fluffy (Feather), or otherwise angled or operations to form the desired shape of a rod. 因此,当施加热和压力以固化棒10时,各层混合在一起成为独特的“一体”或整体结构。 Thus, when applying heat and pressure of 10 bar when cured, the layers are mixed together to become a unique "one" or unitary structure. 而且,在复合层的加热和固化期间,用在集中屈曲区域330的径向外部区域333中的任何阻尼器230和/或阻尼材料优选地与周围复合材料熔合,并变为整个棒结构的整体部分。 Any damper Further, during heating and curing the composite layers, with a concentration in the region of the radially outer region 333 of flexion 330 230 and / or damping material is preferably fused with the surrounding composite material, and the whole becomes integral bar structure section.

[0147] 换一种方式,棒的全部层在单个步骤中被“共同固化”,并在至少一个端部混合或终结在一起,形成无缝隙的一体结构(在至少一端处),从而筒身14不是由一连串的管构成,其中每个管具有终结于管端部处的独立的壁厚。 [0147] Put another way, all the layers stick is "co-cured" in a single step, and at least one end or end portion of mixed together to form a seamless unitary structure (at least at one end), thereby Flashlight 14 does not consist of a series of tubes, wherein each tube has a wall thickness terminating in a separate portion at the tube end. 因此,所有的层在载荷条件下(例如在球撞击期间)是谐调动作的。 Thus, all of the layers under load conditions (e.g., during ball impact) is harmonized operation. 筒身14的一端或两端可以以这种方式终结在一起,以形成一体的筒身14,(根据是否使用任何ISCZ)其包括一层或多层筒壁。 One or both ends of the barrel 14 may be terminated in such a manner together to form an integral barrel 14, (according to whether any ISCZ) comprising one or more tubular wall. 在可替换设计中,筒身的任一端被混合在一起,使得形成了多体结构。 In an alternative design, at either end of the cylinder body they are mixed together so as to form a multiple structure. [0148] 因此,虽然已经示出并描述了几个实施例,但是当然在不背离本发明精神和范围的前提下,可以进行各种更改和替换。 [0148] Thus, while there have been shown and described several embodiments, but of course, without departing from the spirit and scope of the invention, various modifications and substitutions can be made. 因此,本发明在由所附权利要求及其等同物限定之外不应该再受到限制。 Accordingly, the present invention should not be restricted further than defined by the appended claims and their equivalents.
