摘要： A fashionable pair of spectacles with combined sliding and pivoting elements for viewing objects behind a forward facing user. The spectacles have temples at opposite ends of the eyepiece with longitudinal apertures for receiving closely fitting shafts. A pair of slender round shafts engage the apertures and have orthogonal forward end portions which project out of the apertures and receive reflective elements for viewing objects behind the user. In the first aspect of the invention, each reflective element is rotatably mounted to the orthogonal end of one shaft and is selectively adjustable by translating and rotating the shaft along and about the longitudinal axis of the corresponding temple aperture and by rotating the element about the axis of the orthogonal foward portion of the shaft. At the operative positions of the elements, the elements are in confronting relationship to the user and in front of the eyepiece and in the non-operative positions of the elements, the elements are in side facing relationship to the user and the eyepiece. In the second aspect of the invention each element is further adjustable by separating and rotatably attaching the forward end of the shaft to the other part of the shaft.
摘要翻译：一种时尚的眼镜，具有组合的滑动和枢转元件，用于观察面向前面的用户后面的物体。眼镜具有目镜两端的镜腿，具有用于接收紧密配合的轴的纵向孔。一对细长的圆形轴接合孔，并且具有从孔中伸出的正交的前端部分，并且接收用于观察使用者后面的物体的反射元件。在本发明的第一方面中，每个反射元件可旋转地安装在一个轴的正交端上，并且可以通过沿着并围绕相应的镜腿孔的纵轴平移和旋转轴并且通过围绕轴线旋转元件来选择性地调节的轴的正交部分。在元件的操作位置处，元件与用户面对面并且在目镜前方以及元件的非操作位置处，元件与使用者和目镜呈侧向关系。在本发明的第二方面中，通过将轴的前端分离并可旋转地附接到轴的另一部分，每个元件进一步可调节。

摘要： A fashionable pair of spectacles with single pivot folded rear vision elements for viewing objects behind a forward facing user. The spectacles are comprised of a binocular eyepiece of the kind having a conventional frame without side shields, a pair of spaced apart slender temples mounted to opposite ends of the eyepiece for rotation about a first pair of vertical axes and a pair of spaced apart folded elements mounted to the eyepiece for rotation about a second pair of vertical axes which are positioned inside of the first pair of axes. Each rear vision element has a reflective portion and a mounting portion at a fixed angular relationship to the reflective portion. The elements are independently selectively adjustable about the second set of axes to operative positions for viewing objects behind the wearer whereat the reflective portions are forward of the eyepiece in plain view without restriction to the side vision of the user and to non-operative stored positions whereat the reflective portions are in side facing relationship to the user. When the elements are at their non-operative stored positions the appearance of the spectacles is conventional and the folded elements are not readily discernible as separate elements of the spectacles.
摘要翻译：一种时尚的眼镜，具有单个枢轴折叠的后视元件，用于观看面向前面的使用者后面的物品。眼镜由具有不具有侧面屏蔽的常规框架的双目目镜组成，一对间隔开的细长的镜腿安装在目镜的相对两端，用于围绕第一对垂直轴线旋转并且一对间隔开的折叠元件安装到目镜上以围绕位于第一对轴线内侧的第二对垂直轴旋转。每个后视元件具有反射部分和与反射部分成固定角度关系的安装部分。这些元件可以围绕第二组轴独立地选择性地调节到用于观察佩戴者后面的物体的操作位置，其中反射部分在平面图中在目镜的前方，而不受用户的侧视和非操作性存储位置的限制反射部分与用户面对面。当元件处于其非操作存储位置时，眼镜的外观是常规的，并且折叠的元件不容易被识别为眼镜的单独元件。
