Description

可调节运动球拍
背景技术
沙滩板手球(paddle ball)或“Matkot”是一种逐渐流行的发展中的沙滩娱乐。该比赛被认为起源于地中海沿岸、流传至美国并且遍及全国。沙滩板手球由典型地为两至三名参赛者的多名运动员比赛,其中小橡胶球在使用木制球拍的运动员之间被来回地截击。宽的木制球拍或球拍被称为“matka”(该比赛因此而得名),并且比赛的目标是运动员为了努力使球不碰到沙滩而来回地击球。
诸如用于Matkot等的运动球拍和球拍普遍存在并且具有多种形状、尺寸和设计。例如,乒乓球是用包括橡胶或粘性片的木制球拍比赛,其中橡胶或粘性片粘附在木制球拍的表面,然而壁球、网球和羽毛球球拍使用木制、金属或复合材料框,其中弦穿过表面以形成击打区。还有包括沙滩网球、乒乓球等的这些比赛的混合,每种比赛使用不同类型的球拍或拍子。这些比赛和活动中的每一种均使用专用的运动球拍来击打某种球,将球击打到指定的比赛区或在指定的比赛区击打球。运动球拍的性能取决于比赛的目的和球拍的设计,但是一旦球拍被设计好,其在响应、性能和尺寸等方面则通常是固定的。例如,没有有效的方式调节乒乓球拍以选择不同的响应,而在与两个不同的对手比赛时可选择不同的响应可能会成为优点。相似地,风力条件、参赛者的技术水平以及期望控制多于力量(或相反)将使诸如沙滩板手球球拍等的球拍对响应具有一定的可调节性成为优点。在其它情况下,优选地,可以延长手柄以适应不同的运动员、比赛条件等。本发明涉及该目标。
发明内容
本发明是可以用于多种比赛和活动的多用运动球拍,并且提供了此前难以获得的新灵活性和对球拍的响应的控制。该球拍引入了诸如充气气囊等的内部可充气构件,其改变了在碰撞诸如球等的另一物体时球拍的回弹系数(“COR”)。在该应用中,将一维碰撞(线性)的回弹系数定义为分离速度(冲击后速度)与接近速度(冲击前速度)的比率。本发明的球拍包括在手柄中手动操作的泵机构,其推动压缩空气进入可充气气囊,相应地改变了球拍的COR。可以将阀释放以允许空气从气囊泄出而同样改变COR,并且本发明的优选实施方式包括可视化指示器,其示出与最大设计压力相比当前气压位于何处。通过调节气囊中的压力,运动员可以改变运动球拍的响应(即,COR)而在与球/物体的碰撞中获得更大的弹性,增加了运动球拍的柔性和可享用性(enjoyment)。
在优选实施方式中,还可以通过在手柄的端部按运动员的期望增加或移除可堆叠元件使本发明的球拍以快速、可靠的方式缩短或延长。可堆叠元件使手柄逐渐加长,使得运动员可以获得期望的手柄,增加了球拍的通用性。
结合附图并参照以下说明将最好地理解本发明的这些特征和其它特征。

具体实施方式
图1至图3示出本发明的第一优选实施方式,其中绘示了用于包括沙滩板手球和乒乓球等的各种活动和比赛的运动球拍10。球拍10包括手柄12,该手柄12可以具有泡沫握持套、粘性布或缠带(tape wrap)或者其它增强摩擦的表面以使握持符合要求。优选地,手柄可在底部包括商徽、标识或记号14以增加品牌识别度。手柄12连接到支撑结构16,该支撑结构16包括颈部18和大致卵形的框20。大致卵形的框20用于安装具有第一和第二击打面24的成型嵌入件22。优选地,形成为嵌合到卵形框20中的成型嵌入件22由弹性塑料或热塑性塑料制成。成型嵌入件22包括在框20中央的击打区,并且在一些应用中,靠近嵌入件的周界排列有多个孔26。这些孔允许空气容易地穿过并且允许能更自由和更容易地挥摆球拍。空气还可以穿过颈部18。取决于应用和运动员的偏好,孔26的存在和数量可以变化。
在手柄12上位于握持部28上方的是波纹管30或泵装置以及观察玻璃32或光学计量器(optical gauge)。波纹管30可以是能由运动员手动按下的柔性圆拱形结构。一旦将波纹管30按下并释放、波纹管30返回至其原始形状,使得能够反复地泵波纹管。观察玻璃32可包括指示器,其示出计量器下方的隔室中的相对内部气压,该隔室中的气压通过反复地按下波纹管30而增加。运动员能通过使用观察玻璃32观察到压力的增加,并且将该内部气压与计量器上的最大推荐设计压力比较。还可以用其它方式指示内部压力,包括标度盘、LED、光圈(diaphragm)、压力传感器或类似装置。
使内部隔室40通过柔性管44连接到气囊42,其中柔性管44穿过球拍10的颈部18。管44可由更具刚性的材料制成的柱46保护以防止管44的损坏或断开。如图4和图5所示,隔室40经由柔性管44与气囊42流体连通。用手指48按下波纹管30,其中波纹管30优选地利用单向阀(未示出)连接到隔室以增加隔室40的气压。如在观察玻璃32或其它压力指示器中所反映的,每次用手指48按下波纹管30,气压都增加。如箭头50指示的,隔室40中增加的气压还使其所连接的气囊42中的气压增加,增加了嵌入件22内的气囊的坚度(firmness)。随着气囊内的压力增加,击打面的刚度(stiffness)增加,从而增加了球拍10的COR。
如图5所示,还可以通过阀54使气囊42中的气压减小。当打开阀54时,隔室40中的空气通过阀泄出,并且如箭头52指示的相应地使所连接的气囊42中的气压减小。通过选择性地启用阀54和波纹管30,运动员可以通过控制相邻气囊42中的气压来调节球拍10的击打面24的刚度。
图6至图9示出了本发明的球拍的替代实施方式100。在替代实施方式中,支撑结构116包括大致地但不完全地围绕击打区延伸的框118。气囊142以与前述实施方式相似的方式连接至手柄12,但是支撑结构116还包括多个径向地延伸的构件160,构件160使框118连接至包围气囊42的环形或U形梁162。径向构件160还可以终止于周缘164,并且可以使梁162、径向构件160和周缘164成型为单件支撑单元(图7)。尽管所选择的厚度和材料也会改变球拍100的重量和挠曲特性,但径向构件160与缘164和梁162的结合为球拍增加了刚性。
图10至图14示出了本发明的第二优选实施方式。在该实施方式中,手柄12由基部200和多个可堆叠元件构成,其中可堆叠元件可以结合在基部200的端部以增加手柄12的长度。这些可堆叠元件是协作以延长手柄12的长度的、相对薄的同心块202。将螺纹紧固件204放置在与末端块接合的端盖206中,以使构型收拢并创建牢固的、刚性的延长部。紧固件204可以螺接到基部200,不管存在多少个块202(例如,0至4个),该基部200都可以容纳紧固件204。可以在紧固件204与端盖206之间使用垫圈208或者可以使垫圈208凹进端盖中。取决于运动员和使用,块202可以具有不同的密度或重量以为球拍创建不同的使用感。因此,块202可以是软木、木材、铝、塑料、橡胶或者既耐用又可容易地成形以形成手柄段的任何合适的材料。图11示出手柄12处于完全延长的、最大长度的构型,而图14示出手柄处于缩短的构型。移除紧固件204、移除块202、然后再放回紧固件允许在两种配置之间来回切换,与此同时还可以形成中间长度。注意,可以将保护套(未示出)放置在手柄12上以覆盖块202并且为手柄12提供更平滑、更具粘性的触感。
本发明的球拍适用于许多不同的运动和活动,并且具有重量轻、容易构造、模块化和通用化的优点。尽管已说明和绘示了各种实施方式,但本发明不受这些说明和描绘的限制。本领域的普通技术人员将容易地认识到对前述实施方式的特定修改和替换,并且本发明旨在包括全部此类修改和替换。因此,参阅本文的说明书和附图的内容,本发明的范围由所附权利要求正确地限定、赋予其普通和惯用的含义。
