Gegenstand der Erfindung ist ein Sperrschalter zur Verhinderung der Entnahme elektrischer Energie zu bestimmten Zeiten.The invention relates to a locking switch to prevent the removal of electrical devices Energy at certain times.

Fig. 5 und 6 sind den Fig. 3 bzw. 4 entsprechende Darstellungen bei einer Raststellung des Schalters unmittelbar vor Einschaltung,FIGS. 5 and 6 are representations corresponding to FIGS. 3 and 4 in a latching position of the switch immediately before switching on,

Fig. 8 zeigt in einer den Fig. 4 und 6 entsprechenden Darstellung das von der überwachenden Uhr beeinflußte Sperrorgan in seiner der Sperrzeit entsprechenden Stellung.
Die aus Isoliermaterial bestehende und mit den Stromschlußstücken α α ausgerüstete Schaltwalze b sitzt lose drehbar auf einer Welle c, auf welcher in der Nähe des Schaltrades oder Schalterhandgriffes d eine Scheibe e und jenseits der Schaltwalze eine Scheibe f befestigt ist.8 shows, in a representation corresponding to FIGS. 4 and 6, the locking member influenced by the monitoring clock in its position corresponding to the locking time.
The switching drum b, which is made of insulating material and equipped with the current connection pieces α , sits loosely rotatable on a shaft c, on which a disk e is attached near the switching wheel or switch handle d and a disk f is attached on the other side of the switching drum.

Das Schaltrad d sitzt selbst lose auf der Welle c mittels einer Hülse g, welche einen Schaltarm h mit einer unter der Wirkung der Feder i (Fig. 1 und 2) gegen die Scheibe e gedrückten Klinke k trägt. Diese Klinke kann mit einer Nase / der Scheibe e zusammenwirken. Eine Spiralfeder m dient dazu, Schaltrad d und Schaltarm h in die Ruhestellung, entgegen dem Drehsinn des Uhrzeigers, zurückzubewegen.The ratchet wheel d sits itself loosely on the shaft c by means of a sleeve g which carries a switch arm h with a pawl k pressed against the disk e under the action of the spring i (FIGS. 1 and 2). This pawl can interact with a nose / the washer e . A spiral spring m is used to move ratchet wheel d and switch arm h back to their rest position, counter-clockwise.

Die Scheibe f besitzt an ihrem Umfang eine Ausnehmung, so daß zwei entgegengesetzt gerichtete Sperrnasen m¹ und η entstehen (Fig. 4, 6 und 8), auf welche die Sperrzähne 0 bzw. p einer um den Zapfen q drehbaren Sperrklinke r einwirken können. Auf eine seitliche Stützfläche s der Sperrklinke kann ein von dem überwachenden Uhrwerk während der Sperrzeiten vorgeschobener Stift t (Fig. 1 und 8) treffen.The disc f has a recess on its periphery so that two oppositely directed locking lugs m ¹ and η arise (FIGS. 4, 6 and 8) on which the locking teeth 0 and p of a locking pawl r rotatable about the pin q can act. A pin t (FIGS. 1 and 8) pushed forward by the monitoring clockwork during the blocking times can hit a lateral support surface s of the pawl.

Die Schaltwalze b trägt auf der dem Handrad d zugekehrten Seite eine Sperrscheibe u, vor deren Nase ν sich eine unter der Wirkung der Feder ζ (Fig. 2 und 3) stehende Sperrklinke w legen kann, die seitlich einen Stift χ trägt, der mit einer eigenartig pfeilförmig gestalteten hinterschnittenen Spitze y der Klinke k zusammenwirken kann.The shift drum b carries on the side facing the handwheel d a locking disc u, in front of whose nose ν a pawl w under the action of the spring ζ (Fig. 2 and 3) can put, which laterally carries a pin χ , which with a peculiarly arrow-shaped undercut tip y of the pawl k can cooperate.

Zwischen einem Zapfen der Scheibe e und einem Zapfen der Scheibe u (Fig. 1 und 2) ist eine Schraubenfeder 2 ausgespannt. An einem Zapfen der Scheibe f greift eine Schraubenfeder 3 an, deren anderes Ende festliegt.A helical spring 2 is stretched between a pin of the disk e and a pin of the disk u (FIGS. 1 and 2). A helical spring 3, the other end of which is fixed, engages on a pin of the disk f.

Zwei Anschlagstifte 4 und 5 (Fig. 1) an der Schaltwalze begrenzen deren Drehung in beiden Richtungen.Two stop pins 4 and 5 (Fig. 1) on the shift drum limit its rotation in both Directions.

Claims

The mode of operation of the locking switch is as follows: If the switch is to be made during the time released for power consumption, the handwheel d with the sleeve g, arm h and pawl k attached to it is turned clockwise (see FIG. 2) against the pressure of the spring m turned. The pawl k takes the intermediate gear consisting of disk e, shaft c and disk f with it, so that the spring 3 is tensioned. Furthermore, the spring 2 is tensioned, since initially the disk u attached to the shift drum b, on which the other end of the spring 2 engages, is prevented from rotating by the pawl w located behind the nose ν. Here, the parts shown in FIGS. 3 to 7 gradually move from the position of FIGS. 3 and 4 to the position of FIGS. 5 and 6, the nose 0 of the pawl r falls under the action of the spring 8 behind the tooth m1 Disk f, and an inclined surface of the tip y of the pawl k meets the pin χ of the pawl w that the pawl k continues to disengage from the nose I of the disk e of the intermediate gear and then the pawl w is disengaged from the Nose ν of the disk u attached to the shift drum b brings. The latter has the consequence that the switching drum rotates rapidly into the switched-on position (FIG. 7) with relaxation of the spring 2, the contact bridge α, α coming to lie under the contact fingers 9, 9 and stop pin 4 (FIG. 1) the further rotation prevented. The handwheel d with arm h is now prevented from turning back under the action of the spring m, so that the undercut of the tip y of the pawl k catches on the pin χ so that the spring ζ does not open the pin λ; able to pull out of the cut recess. When it is to be switched off, either by hand or by the pin t of the clockwork, the plate s of the pawl r is pressed (FIG. 8). Then the nose 0 releases the ratchet tooth m1, and the spring 3 pulls the intermediate gear back fee. An arm 6 attached to the disk e grips behind the pin 7 attached to the disk u and takes the shift drum back into the switch-off position, which the pin 5 limits. Towards the end of the rotation of the shift drum, the pawl w can fall back behind the nose υ of the disk u, and now the spring ζ can pull the pin χ out of the undercut of the pawl k at y due to the greater possibility of oscillation of the lever, whereby the arm k is released with handwheel d and returns to the rest position under the action of the spring m. So even if you wanted to hold the switch handle d, you could not prevent the switch drum from being switched off. On the other hand, as long as the pin t is pressed by the eccentric driven by the clockwork on the plate s and thereby the pawl r is held in the position of FIG The pawl r would hold the tooth η of the disk f and prevent the intermediate gear from rotating in the sense of the switch-on movement. Of course, all parts of the switch with the exception of the handle d and the plate s or the pin t are enclosed and inaccessible. Godfather τ-An Proverbs:

1. Locking switch to prevent the removal of electrical energy at certain times with an intermediate gear arranged between the switch handle and switch, which biases the switch-on and switch-off springs, at the end of the switch-on movement releases the switch for switching on and disengages from the handle, characterized in that the intermediate gear has a mechanically controlled pawl (r 0 p) is assigned by the monitoring clockwork, which holds the tensioned intermediate gear in one of its two working positions (Fig. 6), releases the gear when it is reversed after the blocking time has elapsed and in the second end position (Fig. 8) locks against being switched on again.

2. Lock switch according to claim 1, characterized in that the switch handle (d) towards the end of the switch-on movement is held by a lock (x, y) which is only triggered again by the switch that switches off.
