Abstract: Disclosed herein is an improved arrangement for the operation of an overhead garage door that comprises an adapter utilized for installation and periodic maintenance of the support arrangement. Also disclosed is an adapter for use with existing garage door structures, improved wrenches for use in tensioning coil springs usually found in such arrangements and a method for tensioning such coil springs when they are originally installed or during periodic maintenance of the springs. The adapter comprises a body that may be mounted upon a rotatable shaft that supports the coil springs and be non-rotatabley attached to an end of the coil spring and the rotatable shaft. The attachment to the shaft is a releasable connection and the body has splines or projecting abutment surfaces so that two of the improved wrenches according to the present invention may have their jaws closely surround and engage the splines on the body. For already existing structures the adapter has an end that is designed to attach to the collar already in place and also be attached to the end of the coil spring. The wrenches have releasable latch means that are designed to engage and disengage with the splines on the adapter body. The method according to the present invention comprises engaging and rotating the splines with the wrenches in an alternate manner such that the coil spring is wound to make the tension greater or less as one desires.

Abstract translation: 本文公开了一种用于操作塔顶车库门的改进布置，其包括用于安装和定期维护支撑装置的适配器。 还公开了一种用于与现有车库门结构一起使用的适配器，用于张紧通常在这种布置中发现的螺旋弹簧的改进的扳手，以及用于在初始安装时或在定期维护弹簧期间张紧这种螺旋弹簧的方法。 适配器包括主体，其可以安装在支撑螺旋弹簧的可旋转轴上，并且不可旋转地附接到螺旋弹簧和可旋转轴的端部。 与轴的连接是可释放的连接，并且主体具有花键或突出的邻接表面，使得根据本发明的两个改进的扳手可以使其夹爪紧密地围绕并接合在主体上的花键。 对于已经存在的结构，适配器具有设计成附接到已经就位的套环的端部，并且还连接到螺旋弹簧的端部。 扳手具有可释放的闩锁装置，其被设计成与适配器主体上的花键接合和脱离。 根据本发明的方法包括以切换的方式使花键与扳手接合和旋转，使得螺旋弹簧被卷绕以使张力大于或等于所期望的张力。
