DE102021005476A1 - Mechanical 2-fold changeover mechanism in the double frame of a changeover switch - Google Patents

Abstract

The invention relates to a double changing mechanism (Figure 01/02, item 100), which is installed in a double frame (Figure 06, item 10) for European rocker sizes, such as rocker sizes 45mm*45mm or 55mm*55mm. The mechanical changeover switch, which is located in the first receptacle, can be actuated from the side of the second receptacle by moving the sliding block (Figure 01/02, item 102).

Description

STATE OF THE ART:

For the expansion with a design-neutral and flat additional drive as a functional extension to an already installed mechanical switch, in particular light switches and/or shutter switches and/or thermostat switches with a double frame, which contain at least two mounts, one mount for an actuator and the other mount for I am not aware of any possible solutions for the mechanical changeover switch and a changeover mechanism integrated in the crossbar of the double frame, this was also demonstrated by patent researchers such as, DE10 2017 115 382 A1 mechanical switch, EP 2 991 087 A1 electrical switch, EP3079209B1 Fastening device, affirmed.

Description:

Mechanical switches are known in the field of electrical installation. If a user is to be provided with additional functions, in particular an electromechanical drive to operate a mechanical switch from a distance, the switch, in particular the electromechanical contact, which includes the galvanic isolation and is therefore a safe, long-lasting installation and does not require stand-by currents, replaced by an electronic switch, which often includes a TRIAC circuit, with such a range of functions
or an electromechanical drive is placed on the existing mechanical switch, which makes manual actuation of the installed mechanical switch more difficult or even impossible.

It is the object of the present invention to provide a 2-fold mechanical changing mechanism which is installed in the intermediate bridge of a double frame ( 04 , Section AA) is housed and thus an actuation coupling between the two recordings ( 03 , item 10). This is below the intermediate bridge and therefore still flat and leaves the design unchanged.

The actuation of the mechanical switch ( 06 ) must still be possible even if the changing mechanism and/or electrical actuator is defective. The toggle switch can be operated manually via the rocker cover ( 03 , item 11) or via the movement of the sliding block ( 01 , Pos102), which is actuated, for example, by an actuator.

A coupling mechanism between the rocker of the mechanical switch and the actuating bolt ( 01 , item 108) or actuating rod ( 01 , item 109) is adapted type-specifically to the mechanical switches relevant to the market.

The actuating pin ( 01 , item 108) or the actuating rod ( 01 , item 109) are designed twice and symmetrically. Symmetrical spacing of operating rods ( 06 , item 109) to each other 30-50mm and the symmetrical distance between the actuating pin ( 01 , item 108) to each other 15-35 mm and both at a height of approx. < 8mm.

• - Vor/Zurück Bewegung (translatorisch) oder
• - Schwenkbewegung ca. +/-15°

Due to the structural design of the mechanical changing mechanism ( 07 ) are different movements on the part of the operating rod ( 07 , item 109) or actuating pin ( 07 , item 108). These are :

• - Forward/backward movement (translational) or
• - Pivoting movement approx. +/-15°

The switch mechanism ( 01 , Item 100) is a double changeover system and is therefore also suitable for 1-way or 2-way rocker switches.

The switch mechanism ( 07 ,Pos. 100) has very small actuation paths on the part of the sliding block ( 07 , Pos. 102), ie < +/- 3mm translatory

• - von der anderen Seite, der Aufnahme für den mechanischen Schalter über Betätigungsstift (01, Pos.108) oder Betätigungsstange (07, Pos.109)

Changing the two turntable forks ( 07 , Pos.106,107) can be done independently:

• - from the side of one shot by moving DOWN/UP or UP/DOWN ( 07 ) of the sliding block ( 07 , Pos.102) from the ZERO POSITION or
• - from the other side, the mount for the mechanical switch via the actuating pin ( 01 , item 108) or actuating rod ( 07 , item 109)

The changing process, i.e. the switching process from the left or right rotary plate fork ( 04 , item 106,107) is driven by the linear movement of the sliding block ( 07 /08, item 102) to the right (UP/DOWN) or to the left (DOWN/UP). For retracting the sliding block ( 07 /08, item 102) to the zero position is moved by the return spring ( 02 , item 104) and the leg spring ( 01 , item 103)

By interposing a spring element ( 12 , Item 111), with simultaneous action, such as manual actuation via the rocker of the mechanical switch - with mechanical coupling with the changeover mechanism - and the translational movement of the sliding block ( 11 , item 102), changing the rotary plate fork ( 09 , item 106,107) can be carried out by manual operation. But the end state or changing state of the rotary plate fork ( 09 , item 106/107) is specified by the longest actuation time. The spring element ( 12 , item 111) possible defects avoided by the force limitation of the actuation via the sliding block ( 12 , item 102).

Preferred exemplary embodiments of the invention are explained in more detail below in the accompanying drawings.
