摘要： An edge protector for a fenestration product is integrally formed of a single sheet of corrugated paperboard that has been perforated, slit, scored, glued, and folded in a particular manner so as to be generally flat in overall configuration prior to being placed in use. At the time of installation, the protector is partially unfolded out of its flat plane to assume an overall generally transversely L-shaped configuration, having a pair of legs intersecting one another at right angles to form a receiving corner for the face and side margins of the product. One leg of the protector forms a flap that covers a marginal portion of the face of the product when the protector is fitted onto the product, while the other leg forms a second flap that covers a marginal portion of the sides of the product. A stiff, relatively short spacer flange comprising a double layer of the material glued together projects edgewise from the outside of the corner in the opposite lateral direction from the side flap to keep the face of the product spaced away from foreign objects. Wrapping of the protector around an outside corner of the product is facilitated by the provision of tear-out tabs embodied in the face flap so that the appropriate tab aligned with the corner of the product may be torn out to leave an empty notch in the flap at that location. The absence of material at the corner of the product eliminates the structural rigidity otherwise afforded by the face flap at that location to enable the protector to more readily bend around the corner.

摘要翻译： 用于开窗产品的边缘保护器由单张瓦楞纸板整体形成，该瓦片纸板已经以特定方式穿孔，切割，刻痕，胶合和折叠，以便在放置使用之前的整体构型基本上是平的。 在安装时，保护器部分地从平坦平面展开，以呈现整体上大致横向的L形构造，其具有一对直角彼此相交的脚，以形成用于面和侧边缘的接收角 该产品。 当保护器安装在产品上时，保护器的一条腿形成覆盖产品表面的边缘部分的折翼，而另一条腿形成覆盖产品侧边缘部分的第二片。 一个刚性相对较短的间隔法兰，包括一层胶合的材料，从角部的外侧沿侧面向侧面方向突出，从而使侧面的外表面与外部物体隔开。 保护器围绕产品的外角包裹，通过提供实施在面罩中的撕开突片来促进，使得与产品的角部对准的适当的突片可能被撕开，以在折片中留下空的凹口 在那个地方。 在产品角落处缺少材料消除了在该位置处由面罩另外提供的结构刚度，以使得保护件能够更容易地绕拐角弯曲。
