Description

The invention relates to a method for dismantling a mounting rail fitted with housings and a dismantling tool. The state of the art refers to the DE 10 2022 101 707 A1 As described there, in control cabinet construction there is a need to line up housings of electrical contact and functional elements (i.e., housings that can be fitted with or are already fitted with electrical contact and/or functional elements) on mounting rails in a predefined quantity and sequence and fix them to the mounting rail – for example, by snapping them into place. The mounting rail can have a hat-like cross-sectional geometry, but it can also have a different cross-section, such as a C-shaped one. The arranging or assembly and subsequent fixing of each individual housing of the contact and functional elements is usually carried out on a mounting rail already installed in the control cabinet and fixed there, for example, to a mounting base. The problem is that sequentially assembling a mounting rail in the control cabinet results in longer cycle times and is inefficient compared to the various advantages of parallel assembly of pre-assembled mounting rails. This problem is solved by DE 10 2022 101 707 A1 surprisingly well by an arrangement with a mounting base and a support rail on which a plurality of interconnectable housings, equipped with electrical contact and/or functional elements, can be arranged, wherein the support rail can be mounted on the mounting base in a mounting position, and in particular can also be mounted on the mounting base in a state when the housings have already been lined up on the support rail before the support rail is mounted, wherein the support rail is held on the mounting base by two or more locking means which are attached to the mounting base before the support rail is mounted, wherein the locking means and the support rail are designed in such a way that the support rail can be placed on the locking means without tools and locked onto them. Furthermore, the locking device is provided to have a base section, wherein the base section has a cross-section corresponding to a U rotated by 180°, the base section being divided into a horizontal base web and two perpendicular side webs, and the locking element being supported on the mounting base via the two side webs as abutments, and wherein the locking device has one or more locking arms for firmly locking the support rail onto the mounting base. This creates a particularly robust snap connection that remains securely in place even after prolonged use, designed in the manner of a snap-hook locking connection. This solution has proven itself in practice, however, it would be desirable to make it easier to detach the mounting rail from the mounting base. The invention aims to solve this problem. The invention solves this problem through the method of claim 1, the disassembly tool of claim 4 and the arrangement of claim 13. The invention thus provides, firstly, an advantageously simple method for dismantling a support rail fitted with housings, which is locked onto one or more locking devices, wherein the respective locking devices are attached on one side to a mounting base and wherein the respective locking devices extend through one or more through holes, in particular elongated holes, of the support rail and are locked onto the support rail on the side of the support rail facing away from the mounting base with one or more locking arms, is characterized by at least the following steps: a) if the locking devices are not accessible with a disassembly tool: if necessary, remove some of the housings so that the locking devices are accessible; b) Placing the at least one assembly tool with at least one tool head having at least one or more locking receptacle(s) onto a respective locking element such that, when the disassembly tool is placed on the tool, the locking arms are moved into a position in which they are at least flush with the respective through-hole in which they are locked, or project slightly inwards beyond the circumferential edge of the through-hole, in particular the elongated hole, so that the locking of the respective locking arm or arms is released when entering or after entering the respective locking receptacle(s), and c) Lifting the support rail from one or more of the locking devices and the mounting base. It should be noted that the term "mounting base" in this document also includes, that one or more elements such as fittings are attached to a base plate or base wall of the mounting base, on which the locking device(s) are then attached. This advantageously practical and simple method can be implemented in various ways. If, for example, the mounting rail is locked to the mounting base with two locking devices positioned relatively far apart, the locking mechanism can initially only be released at one of the devices. This release can be achieved directly by the inner contour of the locking device release recess(s) when the disass
