Abstract: This symmetrical corner connector is particularly useful for sliding door hardware and fastens on without screws or other connectors. Such a door has a panel having a G-shaped stile along each side and a U-shaped rail at the top and bottom, all of which engage the edges of the panel to form the structure of the door. The connector has a central channel for receiving a door suspension member and, on each side thereof, has a wing for engaging the back wall of the stile. An ear on each side of the connector near one end fits over the end of the stile to engage the interior thereof. A tang on each side near the opposite end of the connector fits through a slot in the stile and engages it in opposition to both the ear and wing. In addition, the tang has a spring clip for engaging the interior of the stile for preventing withdrawal of the tang. A hook extends over the top of the rail and through a slot to engage the front face of the panel.

Abstract: A spring hinge is provided for bifold doors such as are commonly used on closets. The doors have a thin panel bounded by U-shape end rails and hollow side stiles. Each hinge leaf serves as a corner connector for an adjacent stile and rail. The hinge leaves are pivoted beyond the end of the door and have stops for limiting the degree of pivoting. Each connector has a rail arm extending over the rail and having depending portions that engage the rear of the rail and the front of the panel. The connector also has a stile leg normal to the rail arm that fits snugly inside the stile and includes a barb for inhibiting withdrawal from the end of the stile. The hinge has a over-center spring action that closes the doors when they are nearly closed and opens the doors when they are nearly open and retains the doors in those positions respectively. A power pack having two pivotally interconnected U-shaped rigid members displaces the driving spring away from the ends of the doors to provide clearance. In one embodiment of power pack, the rigid members are formed of sheet metal and pivotally interconnected without a pin joint. In another embodiment the power pack is molded of plastic with an integral web between the rigid members forming the pivot.

Abstract translation: 弹簧铰链设置用于通常用于橱柜的双门门。 门具有由U形端轨和中空侧框限定的薄板。 每个铰链叶片用作相邻立柱和轨道的角连接器。 铰链叶片转动超过门的端部，并具有用于限制旋转程度的止挡件。 每个连接器具有在导轨上延伸的轨道臂，并且具有接合轨道后部和面板前部的悬垂部分。 连接器还具有垂直于轨道臂的稳定的腿部，其紧密地配合在立体体内，并且包括用于阻止从立柱末端退出的倒钩。 铰链具有过中心的弹簧动作，当门几乎闭合时关闭门，并且当它们几乎打开时打开门并且分别将门保持在那些位置。 具有两个枢转互连的U形刚性构件的动力组件将驱动弹簧从门的端部移开以提供间隙。 在动力组件的一个实施例中，刚性构件由金属板形成并且枢转地互连而没有销接头。 在另一个实施例中，动力单元由塑料模制，在形成枢轴的刚性构件之间具有一体的腹板。
