Embodiment Construction

[0015] FIG. 1 schematically shows an embodiment of a locking mechanism 1 according to the invention. The locking mechanism 1 has a button 2 , which rests with its pin-like extension 3 on the force transmission element 4 . The force transmission element 4 has a guide frame 5 in which the displacement part 6 is guided so as to be movable in the direction of linear movement. The guide frame 5 is fastened movably around a fixed pivot bearing 7 and is connected to a rocker 9 at the bearing 8 .

[0016] In the unlocked position shown in FIG. 1 , the force transmission member 4 bears against the unloading trigger 10 with its longitudinally movable push part, and during actuation, that is, by introducing an arrow along the diagram in the unloading trigger 10 The push movement in the direction releases the locking of the accumulator not shown in the figure, thereby unloading the accumulator.

[0017] In the illustrated exemplary embodiment, the energy store is mechanically connected ...

Abstract

In order to provide a locking mechanism (1) in order to prevent a force store from being discharged in the case of a switch in the field of electrical power distribution having a pushbutton (2) which, when the locking mechanism (1) is in an unlocked position, is coupled by means of a force transmission element (4) to a discharge initiator (10) for discharging of the energy store via an interlock,such that a switching-on movement acting on the pushbutton (2) can be introduced via the force transmission element (4) into the discharge initiator (10) in order to relieve the load on the force store, with the force transmission element (4) being connected to interlock interruption means (9, 17) which are designed to move the locking mechanism (1) to a locked position in which the interlock is cancelled, with the pushbutton (2) and the force transmission element (4); being guided in the unlocked position such that they move in a common longitudinal direction, such that a pushing movement ofthe pushbutton (2) can be introduced into the switching-on initiator (10) via a longitudinal movement of the force transmission element (4), which locking mechanism (1) is mechanically compact and operates reliably, it is proposed that the force transmission element (4) be mounted such that it can pivot such that, in a locked position, a movement direction of the force transmission element (4) isaligned at an angle to the pushing movement of the pushbutton (2), with the interlock interruption means (9, 17) being coupled to a drive shaft (11) of the switch and / or to an auxiliary switch.

Description

technical field [0001] The invention relates to a locking mechanism for preventing unloading of an energy accumulator when a switch is located in the power distribution area, the locking mechanism comprising a push button, which is in the unlocked position of the locking mechanism by means of a force transmission element Form-fit connection to the release trigger for energy storage release, so that the switch-on movement acting on the pushbutton can be conducted via the force transmission element to the release release trigger for energy storage release , wherein the force-transmitting member is connected to a disconnecting device designed to transfer the locking mechanism to a locking position in which the form fit is canceled and the button and the force-transmitting member move in a common longitudinal direction ground into the unlocked position, so that the pushing movement of the button can be introduced into the switching trigger via the longitudinal movement of the forc...
