- This groove has a substantially heart-shaped shape 26 in the inner half of the organ 6, which on the FIG. 1 protrudes from the organ 5.
- the groove 25 has a rectilinear portion 27 which extends symmetrically to the axial axis of symmetry from the apex of the heart to the outer end of the organ 6 and is interrupted by a transverse web 28 in the vicinity of this end.
- the heart-shaped portion 26 of the displacement path of the nose of the arm forming groove has two laterally offset from the axis of symmetry and parallel to the axis XX extending straight groove portions 29, 30 of different lengths.
- the shorter portion 29 is connected to the rectilinear axial portion 27 by a rectilinear connection portion 31 which is inclined with respect to the axial portions 29, 30 at a relatively small angle.
- the second axis-parallel groove portion 30 is connected to the axial and central groove portion 27 by a wider but shorter and steeper groove portion 38.
- the heart-shaped groove portion 26 is closed to the free end 12 of the member 6 through a substantially Z-shaped wall 32.
- This wall has an outer wall portion 33 which extends from the outer wall of the shorter axially parallel groove portion 29 obliquely to the axis of the part 6 in the direction of the free end 12, and a central wall portion 34 which is substantially parallel to the wall portion 31 to the axis, However, in the opposite direction to the part 33 extends and forms with the latter a V, the tip of which is directed towards the end face 12.
- the end 36 of the central wall portion 34 is located with respect to the axis XX of the inner axis member 6 at a distance which is smaller than the distance from this axis
- a wall 39 connects, in the illustrated embodiment of the invention approximately at right angles to the wall portion 34 practically to the outer wall 40 of the longer axially parallel groove portion 30 extends, except for a short mouth part, which is directed approximately at right angles to this wall 40.
- the Z-shaped wall 32 opposite the heart-shaped groove 26 is bounded by an inner wall 42.
- the inner wall 42 has a V-shaped profile, the tip 43 is directed away from the free end 12 and thus causes a latching of the nose 23 of the resilient arm 16.
- the bottom of the groove part 45 which connects the two axially parallel Herznuten Schemee 29 and 30 between the boundary walls 39 and 42 increases progressively toward the groove portion 30 so that in the extension to the groove portion 30 bounded inner wall 46, a step 47 is present, which extends to the outer wall portion 39 of the Z-shaped end wall 32.
- the nose 23 at the end 21 of the elastically deflectable arm 16 of the outer axle member 5 is formed according to the configuration of the groove in which it slides.
- the front side surface 49 of the nose 23 has a V-shaped profile which corresponds to that of the two wall parts 33, 34 of the Z-shaped end wall 32 of the heart-shaped groove 26.
- the inner side 50 of the nose 23 also has a V-shaped profile which corresponds to that of the inner wall 42 of the kaunutteils 45.
- the Nutenground directed towards the end face 51 of the nose 23 is chamfered in a region 52, corresponding to the ramp in the bottom of the kausnutteils 45th
- FIG. 2 shows the device in the non-recessed position of the knob 2, in which it can be rotated.
- the outer axle body 5 is thereby held axially on the inner body 6, in spite of the compression spring 7 apart, that the nose 23 of the spring arm 17 with its rear side surface 50 on the corresponding profile having a crosspiece 28 which interrupts the groove 27, is applied.
- This engaging behind the web 28 through the nose 23 was due to the elastic radial deflection to the outside of the end 21 of the arm 16 when attaching the outer axle member 5 on the inner axle member 6 allows.
- the arm 16 is in its central, laterally deflected position. He is not deformed in the lateral direction.
- the button is pressed into the control panel, so that he on the FIG. 3 represented position and locked in this position.
- the nose 23 of the resilient arm 16 slides first in the rectilinear central groove 27 and then along the inner wall of the oblique groove portion 21 and the subsequent axially parallel groove portion 29 until it abuts the Z-shaped closure wall 32 of the heart-shaped groove 26 in the area of the walls 33 and 34.
- the nose 23 slides under the action of the axial compression spring 7 and the elastic restoring force of the spring directed towards the axis XX along the oblique walls 34 and 42 of the transverse Groove connection part 45 until the nose 23 then engages in the recess of the V-shaped groove wall 42.
- the arm is again in its neutral, laterally undeformed middle position.
- the nose 23 slides along the inclined groove wall 39 in the axially parallel groove 30 of the heart-shaped guide groove 26.
- the nose can freely under the force of the compression spring 7 in the straight groove area 30, the oblique, adjoining groove portion 30 and the axial groove portion 27 slide, so that the head 2 in his on the FIG. 2 shown external position can return.
- the step 47 prevents the arm end from returning to the transverse region 45.
- the resilient arm 16 extends with its free end in the direction of the inner end 11 of the outer axle body 5. As a result, the arm is subjected to train and bending.
- FIGS. 16 to 29 show another embodiment of a retractable rotary handle device according to the invention.
- the different in their form but functionally comparable to the first embodiment of the organs, parts and detail have the same reference number, but now provided with an apostrophe.
- the resilient arm, now designated 16 ' extends with its free end 31, in the direction of the end of the outer axle body 5' carrying the turret.
- the root 17 'of the arm is located near the free end 11' of this organ 5 '.
- the arm 16 ' is radially and laterally in a corresponding window 18' in the wall of the sleeve-shaped member 5 'elastically deflected.
- the outer sleeve 6 ' has an axially directed slot 53 which is diametrically opposed to the arm 16' and is substantially closed at the level of the nose 23 'and the root of the arm 16' at its ends.
- the inner axis organ 6 ' on which the outer member 5' in his on the FIGS. 22 to 26 shown second embodiment, has a guide groove 25 'for the nose 23' of the spring arm 16 ', which has substantially the same structural features, as the guide groove 25 of the first embodiment, as the FIGS. 17 to 21 can be seen.
- the groove 25 'in the outer half of the organ 6' and has only a small depth, in particular the FIGS. 16, 18 and 21 demonstrate.
- the central groove portion 27 ' extends to the outer end of the member 6', which has at this point an axial projecting tongue 55 having the width of the groove.
- the Z-shaped closure wall 32 'of the heart-shaped groove 25' is now located approximately in the middle of the length of the organ 6 '.
- the inner walls of the heart-shaped groove 26 ', on which the nose 23' slides upon actuation of the device, are formed as side walls of an island-like corresponding projection 56.
- an axially extending radially resiliently deflectable arm 59 cut out, the root of which is from the bottom of serving for receiving the compression spring 7 axial cavity to the inner end of the organ extends.
- This arm 59 has a projection 60 projecting radially outwardly beyond the peripheral surface of the member, which has a chamfer 61 on its side directed towards the root of the arm 59.
- This arm 59 with its projection 60 and its chamfer 61 is elastically radially inwardly displaceable when pushing the outer member 5 ', and then engages in the slot 53 of the outer organ 5 ', with the result that the two organs 5' and 6 'remain connected despite the action of the compression spring 7.
- FIGS. 7 and 20 and 29 show the device in its two end positions. Again FIG. 28 can be seen, now the two axis organs are held together by their assembly that the projection 60 of the arm 59 engages behind the boundary wall of the slot 53 and is blocked in this position. The intervention of the projection in the slot was possible during assembly thanks to the chamfer 61 of the projection.
- the guidance of the nose of the elastic arm is practically only effected by the island-shaped inner wall of the heart-shaped guide track, so that the groove is possibly no longer necessary.
- unlike the first of the resilient arm 17 ' is not claimed to train, but to pressure.
- FIGS. 30 to 34 show a variant of the second embodiment, in which the resilient arm is subjected to pressure.
- the peculiarity of this embodiment is that the nose 23 'of the spring arm 16' when released from its retracted position after renewed pressing of the knob longer than before and is performed relatively gently from its laterally deflected position in its central rest position.
- the bottom of the heart-shaped slide track is executed Petrolebnig and has the nose 23 'of the resilient arm 16' has a small cylindrical radial projection 64 on its end face.
- the lateral paraxial groove portions 29 ', 30' in the vicinity 65 of the heart-shaped central elevation 56 ' are shallower than in the rest of the groove region, forming an axially parallel step 66 which extends parallel to the axis somewhat beyond the tip and then angled towards the axis.
- the massively executed nose 23 'on the mechanical loads
- the projection 66 is used for guiding when the nose slides in the axis-parallel groove part and then to the central axis.
- the embodiments shown and described only as an example have in common that they are formed only by assembling three components, namely the two rotatably connected to each other, but axially displaceable to each other axis member and the compression spring.
- the axle parts are advantageously designed as castings and made of plastic.
- the assembly of the device is extremely simple and requires only the insertion of the compression spring in the outer axis organ and then the axial insertion of the inner organ in the outer organ, the organs then through means integral with the organs are held together against the force of the spring between them.

Drehgriffvorrichtungen der vorgenannten Art sind bereits bekannt. Diese bekannten Vorrichtungen weisen jedoch den Nachteil auf, daß das in der Führungsbahn, die als Nute ausgebildet ist, geführte Organ als zusätzliches separates Teil ausgeführt ist, das in das äussere hülsenförmige Achsenteil quer zu dessen Längsachse verschiebbar eingesezt werden muß, was den Aufbau und die Montage der Vorrichtung verkompliziert.Turning handle devices of the aforementioned type are already known. However, these known devices have the disadvantage that in the guideway, which is designed as a groove, guided body is designed as an additional separate part which must be slidably inserted into the outer sleeve-shaped axis part transverse to its longitudinal axis, which the structure and the Assembly of the device complicates.

An den mittleren Wandteil 34 der im wesentlichen Z-förmigen Abschlußwand 32 des herzförmigen Nutenteils 26 schließt sich eine Wand 39 an, die im dargestellten Ausführungsbeispiel der Erfindung ungefähr rechtwinklig zum Wandteil 34 praktisch bis zur Aussenwand 40 des längeren achsparallelen Nutenteils 30 verläuft, abgesehen von einem kurzen Einmündungsteil, der etwa rechtwinklig zu dieser Wand 40 gerichtet ist.The heart-shaped
Der Z-förmigen Wand 32 gegenüberliegend wird die herzförmige Nut 26 durch eine Innenwand 42 begrenzt. Die Innenwand 42 besitzt ein V-förmiges Profil, dessen Spitze 43 vom freien Ende 12 weggerichtet ist und damit ein Einrasten der Nase 23 des federnden Arms 16 bewirkt. Der Boden des Nutenteils 45, der zwischen den Begrenzungswänden 39 und 42 die beiden achsparallelen Herznutenbereiche 29 und 30 miteinander verbindet, steigt in Richtung zum Nutenbereich 30 progressiv an, sodass in der Verlängerung zu der den Nutenbereich 30 begrenzten Innenwand 46 eine Stufe 47 vorhanden ist, die sich bis zum äusseren Wandteil 39 der Z-förmigen Abschlußwand 32 erstreckt.The Z-shaped
Die Nase 23 am Ende 21 des elastisch auslenkbaren Arms 16 des äusseren Achsenorgans 5 ist entsprechend der Gestaltung der Nut, in der er gleitet, ausgebildet. Zu diesem Zweck besitzt die vordere Seitenfläche 49 der Nase 23 ein V-förmiges Profil, das dem der zwei Wandteile 33, 34 der Z-förmigen Abschlußwand 32 der herzförmigen Nut 26 entspricht. Die Innenseite 50 der Nase 23 hat ebenfalls ein V-förmiges Profil, das dem der Innenwand 42 des Verbindungsnutteils 45 entspricht. Die zum Nutengrund hin gerichtete Stirnfläche 51 der Nase 23 ist in einem Bereich 52 abgeschrägt, entsprechend der Rampe im Boden des Verbindungsnutteils 45.The

Bei der zweiten Ausführungsform ist in der Wand des Organs 6' der Nut 25' diametral gegenüberliegend, ein sich axial erstreckender radial federnd auslenkbarer Arm 59 ausgeschnitten, dessen Wurzel sich vom Boden des zur Aufnahme der Druckfeder 7 dienenden axialen Hohlraums aus zum inneren Ende des Organs hin erstreckt. Dieser Arm 59 besitzt einen radial nach aussen über die Umfangsfläche des Organs vorragenden Vorsprung 60, der auf seiner zur Wurzel des Arms 59 hin gerichteten Seite eine Abschrägung 61 aufweist. Dieser Arm 59 mit seinem Vorsprung 60 und seiner Abschrägung 61 ist beim Aufschieben des äusseren Organs 5' elastisch radial nach innen auslenkbar, und greift dann in den Schlitz 53 des äusseren Organs 5' ein, was zur Folge hat, daß die beiden Organe 5' und 6' trotz der Wirkung der Druckfeder 7 verbunden bleiben.In the second embodiment, in the wall of the member 6 'of the groove 25' is diametrically opposed, an axially extending radially resiliently
Die Wirkungsweise der zweiten Ausführungsform der Erfindung entspricht im wesentlichen der der ersten Ausführungsform und braucht daher nicht von neuem näher beschrieben zu werden. Die

Wie die Figuren zeigen, sind die seitlichen achsparallelen Nutenbereiche 29', 30' in der Nähe 65 der herzförmigen zentralen Erhebung 56' flacher als im übrigen Nutenbereich, unter Bildung einer achsparallelen Stufe 66, die sich bis etwas über die Spitze hinaus parallel zur Achse erstreckt und dann zur Achse hin abgewinkelt ist.As the figures show, the lateral paraxial groove portions 29 ', 30' in the
Nach der Freigabe der Nase 23' des federnden Armes 16' aus seiner verriegelten Stellung, infolge eines erneuten Eindrückens des Drehknopfes, kommt der kleine Vorsprung 64 auf der Stirnfläche der Nase 23' seitlich in Anlage an die Stufe 66 und gleitet unter Wirkung der Druckfeder entlang des achsparallelen Bereiches der Stufe und dann des sich daran anschließenden schrägen Stufenbereichs praktisch bis zur Mittelachse der Kulissenbahn. Dank dieser "sanften" Führung wird eine zu schnelle, nahezu sprunghafte und geräuschbildende Rückkehr des Armes in seine Neutralstellung verhindert.After the release of the nose 23 'of the resilient arm 16' from its locked position, as a result of a renewed indentation of the knob, the small projection 64 'comes laterally into contact with the
Bei dieser Ausführungsvariante nimmt wie bisher die massiv ausgeführte Nase 23' die mechanischen Belastungen auf, wohingegen der Vorsprung 66 zur Führung dient, wenn die Nase in dem achsparallelen Nutenteil und dann zur Mittelachse hin gleitet.In this embodiment, as before, the massively executed nose 23 'on the mechanical loads, whereas the
Den lediglich als Beispiel dargestellten und beschrieben Ausführungsformen ist gemeinsam, daß sie lediglich durch Zusammenbau von drei Bauteilen gebildet werden, nämlich den zwei drehfest miteinander verbundenen, jedoch axial zueinander verschiebbaren Achsenorgan und der Druckfeder. Die Achsenteile sind in vorteilhafterweise als Gußteile ausgeführt und bestehen aus Kunststoff. Der Zusammenbau der Vorrichtung ist äusserst einfach und erfordert lediglich das Einsetzen der Druckfeder in das äussere Achsenorgan und dann das axiale Einschieben des inneren Organs in das äussere Organ, wobei die Organe dann durch einstückig mit den Organen ausgeführte Mittel gegen die Kraft der Feder zwischen ihnen zusammengehalten werden.The embodiments shown and described only as an example have in common that they are formed only by assembling three components, namely the two rotatably connected to each other, but axially displaceable to each other axis member and the compression spring. The axle parts are advantageously designed as castings and made of plastic. The assembly of the device is extremely simple and requires only the insertion of the compression spring in the outer axis organ and then the axial insertion of the inner organ in the outer organ, the organs then through means integral with the organs are held together against the force of the spring between them.
Es ist noch anzumerken, daß die verlängerte Führung gemäß den
