    • Disclosed herein is a shutter actuating mechanism for a photographic camera. The mechanism comprises a pair of spaced members adapted to be engaged by the thumb and forefinger of the camera user, and a resilient member positioned therebetween. A pinching or squeezing movement between the finger thumb and forefinger causes the spaced members to move toward each other, thereby producing a displacement of the resilient member. Such displacement of the resilient member produces a force which is used to actuate a shutter. Preferably, the spaced members, the resilient member and a plurality of coupling hinges comprise a one piece plastic structure having a constant transverse cross section, whereby the shutter actuating mechanism can be produced by conventional extrusion techniques.
    • 本文公开了一种用于照相机的快门致动机构。 该机构包括一对间隔的构件,其适于与照相机使用者的拇指和食指啮合,以及位于其间的弹性构件。 手指拇指和食指之间的挤压或挤压运动使间隔开的构件朝向彼此移动,从而产生弹性构件的位移。 弹性构件的这种位移产生用于致动活门的力。 优选地,间隔开的构件,弹性构件和多个联接铰链包括具有恒定横截面的单件塑料结构,由此快门致动机构可以通过常规的挤压技术制造。

    • An improved racket is provided for use in tennis and the like which is believed to enable a user to hit with more power while reducing the torsional forces on the arm. The racket of the invention includes a handle having a bent or offset portion which is of such a shape that the centerline of the racket head is substantially colinear with that of the forearm of the user and thus the racket head is effectively an extension of the arm. When viewed in plan, the throat or shaft of the racket is preferably offset downwardly about 32.degree. relative to the grip or butt portion of the handle while the racket head is preferably offset upwardly about 5.degree. relative to the throat. The racket also includes an improved grip which is fit to the hand of the user.
    • 提供了用于网球等的改进的球拍,其被认为能够使用户能够在减少臂上的扭转力的同时击打更多的动力。 本发明的球拍包括具有弯曲或偏移部分的手柄,该弯曲或偏移部分的形状使得球拍头部的中心线与使用者的前臂的中心线基本上共线,并且因此球拍头部有效地是手臂的延伸部 。 当以平面方式观察时,球拍的喉部或轴优选地相对于手柄的手柄或对接部分向下偏移约32°,而球拍头部优选地相对于喉部向上偏置约5度。 球拍还包括适合用户手的改进的抓地力。
