Crank-shaped! Your pusher.

The fire refers to a crank-shaped lever handle, in particular inside handle for ÜJisenbahn passenger coaches.

It is well known that the inside handles on passenger coaches are the German Federal Railroad designed in the shape of a crank, so that when it is pressed down, the for is easy to open can be »Here there is the disadvantage» that travelers » especially adolescents or children by playfully or thoughtlessly pressing down the inside handle Pick up Sürrersehluss and get out of the car while driving can fall.

It has therefore been proposed "ά & η inside handle of a 3? Train ürverSchlusses so that the effective, the castle or the latch retreating ^ etätigungshub a return stroke of the pusher is preceded by which this is brought into a position in which the -Herunterdrücken not is possible. iüine proposed embodiment of such a configuration is provided with a fitted onto the pusher mandrel Drückernabe "compete against the driving claw of the pusher mandrel in the mandrel between the handle and a clutch incorporated Büchee, de ren claws angeordnet.ist a return spring. With this training, difficulties arise in the handling of the pusher by travelers who cannot recognize the particular mode of operation.

The firing is now based on the thank you »the lürrücker to be trained in such a way that neither the dangerous playful pushing down nor the door handle through its unusual rest position makes the special handling easily recognizable and inevitably brings about it.

To. This is the purpose of the trigger according to the control

designed in two parts, the two files by one Q-elenkquerzapfen tiltable with each other against a support spring are connected and the front rope carrying the handle hub has a recess into which a claw located on the other part of the mandrel enters in the tilted position.

As a result of this design, a lever handle is created which has an idle stroke upstream of the effective actuation stroke, but whose direction of movement is opposite to the actuation stroke. This achieves a favorable rest position of the handle »and an obvious and tangible direction of actuation for the handle is made recognizable, furthermore the traveler is prompted to open the door willingly» by tilting the inside handle by pressing against the door or the Pusher takes place *

In these circumstances, a playful or divorced thoughtless opening of the reading material and the associated ones The risk of accidents is avoided.

According to the innovation, there is a simple, robust and reliably working form of such training in that a groove is cut into the rear face of the front half of the handle, which is beveled on one side is, the bottom of which is recessed on one side according to the bevel and continued to form a segment-shaped incision in the sleeve is, in both of which one on the other part of the pusher mandrel seated bar enters.

This embodiment results in an advantageous limitation of the tilting movement of the crank lever with the coupling of the hub the same with the trigger.

According to the innovation for the storage of support springs, the opposing halves of the pusher mandrel can now be used Provided with blind holes on the bevels, in which these are embedded as 3 screw pressure springs.

The tilting joint is advantageously simple as a result designed that, according to the innovation, the joint cross pin dureJ * the bar and the cap cheeks of the two-part trigger mandrel passes through.

To support the inner handle in its cradled position against bumps and the like.

On the drawing the hiring is in one execution shown as an example, s

The crank handle provided as the inside handle on the outer doors of passenger coaches consists of a button 1 carrying crank arm 2, the honeycomb 3 of which is rotatably mounted on the handle mandrel extension 4 of the handle mandrel 5, which is firmly connected to the lock nut 5, which is not shown 4 and the pushing hub attached and secured by a screw 6. A coupling sleeve 7 is embedded, the claws 8 of which enter into driver recesses 9 of a driver sleeve Io fixedly arranged in the driver hub 3. In a recess 11

A return spring 12 is inserted into the coupling ^{sleeve 7, which engages with one leather end 12 f} on the sleeve 7 and with the other end 12 ** on the pusher mandrel extension 4.

The coupling sleeve 7 has a on its end face sector-shaped cutout 13 from about 90 ° to »in the one Stop pin 14 protrudes and that brought about by the peder effect Rotation of the coupling sleeve 7 limited »which endeavors the sleeve and at the same time the crank handle in the direction of the arrow χ i Fig. 3) to move

As mentioned, the pusher mandrel is designed in two parts and the two parts 4 and 5 are formed by a selenium cross pin. connected to one another so that they can be bent against the pressure of a support spring 16. To mount the support spring 16, the mutually abutting halves of the push-button mandrel are provided with blind holes 17 '' from their ends.

A diametrically extending groove 2o is cut into the rear end face of the head-like thickening 4 ^{f of} the front pusher part 4, which is provided with a bevel 19 on one side, the base of which is recessed on one side corresponding to the bevel 19, so that a discharge pit 2o 'for the pusher pin part 5 seated bar 21 formed lot *

A stop pin 23 is provided on the key plate 22 »against which the crank arm 2 of the handle steps ·

If the crank handle is pivoted upwards in the direction of the arrow j Xn , the edge 12. This pivoting is limited by the pin 14 in such a way that one edge 13 of the cutout 13 of the sleeve 7 is in front of the edge of the bar 21 is "In this position it is possible" to bend the handle by pressing the handle in the direction of the opening movement of the door, as shown in Fig. 4 and 5. Here the edge 13 * lies against the side surface of the bar 21 (see Fig. 5) and now “when the handle is pressed down in the direction of the arrow χ , the lock is opened or all of it is pushed back.

When the crank pusher 3 is released, the support spring advertises the crank position of the front mandrel part 4 _y. The edge 13 * slides off the bar 21 and the buckle spring 12 guides the pusher back into the height division »cUh · abutment on the stop pin 23.

In general, an operre in Oohlossmecirianism holds the latch of the lock in a pre-latching position that facilitates the usual slamming of the ¹ I ¹ Ur, and the pusher pin also remains in a corresponding position. When the lock is released when the door is slammed shut, the handle mandrel rotates back into its basic position.

To ensure that the handle hub 3 is closed on the key plate to achieve »is also the edge 3 * of the $ abe, as from Fig * 4 can be seen, obliquely flattened in the corresponding angular position, so that this band 3 * In the ibene of Flattening 19 of the mandrel part 4 * lies and not, the kinking prevents.
