Description

The present invention relates to a pull handle for unlocking a lock of a vehicle door or flap, in particular a door or flap of an agricultural vehicle, e.g. a tractor, or a construction machine.

Such a vehicle door lock is for example from the DE 10 2006 012 956 A1 known. This vehicle door lock has two rotary traps, between which a locking pin can be added. In a locked position of the vehicle door lock, the rotary latches surround the latch bolt so that the vehicle door is held in its closed position. The two rotary traps are held by two pawls in their holding the locking pin position. The pawls lock so the rotary latches. This lock can be released by means of an actuating lever. The operating lever engages in the lock case. Rotation of the operating lever causes the pawls to release the latches and then release the latch pins.

The unlocking of a vehicle door lock, so in the case of DE 10 2006 012 956 A1 the operation of the actuating lever, it can be done eg by means of a push button or a pull handle. The push button or the pull handle then has in each case an actuating mechanism for unlocking the lock, which in the case of DE 10 2006 012 956 A1 is in communication with the operating lever. The actuating mechanism can be opened and closed, for example by means of a cylinder lock. If the operating mechanism is locked, the lock can not be unlocked. This is known per se.

A vehicle pull handle is for example from the DE 103 43 355 B4 known. This pull handle has a bearing housing with a mounting base plate, a pivotally connected to the mounting base operating handle and an actuating mechanism for unlocking a rotary latch lock on. The operating handle is mounted on a pin, which is also mounted on the mounting base plate. A spring unit urges the operating handle in its non-actuated normal position. The actuating mechanism of the pull handle has a connecting element which is fixedly connected to the actuating handle and thus rotates with this when actuated. The connecting element passes through a recess in the bearing housing and the mounting base plate and is in direct operative connection with the rotary latch lock. The pull handle also has a locking mechanism with a cylinder lock, by means of which the actuating mechanism can be blocked. A locking strip of the locking mechanism is brought by rotation of the cylinder by means of a suitable key in a position in which he locks the movement of the operating handle. An actuation of the operating handle is then no longer possible. The closing strip is arranged outside of the bearing housing.

The object of the present invention is to provide a pull handle for a vehicle door or flap, in particular a vehicle door or flap of an agricultural vehicle, e.g. a tractor or a construction machine that is functionally reliable and can be easily connected to the lock.

This object is achieved by a pull handle according to claim 1. Advantageous developments of the invention are characterized in the subsequent subclaims.

The pull handle 1 (according to the invention) Fig. 1-3 ) has a pull handle housing 1a with a bearing part 2 and a pivotally connected to the bearing part 2 handle part 3, arranged in a pull handle housing 1a actuating mechanism 4 for unlocking a lock, in particular a rotary latch lock, and arranged in a pull handle housing 1a locking or closing mechanism 5 for blocking of the actuating mechanism 4 and for decoupling the actuating mechanism 4 from the handle part 3. By means of the closing mechanism 5, the actuating mechanism 4 is openable and lockable, that is to say it can be brought out of operation such that pulling on the handle part 3 does not cause any unlocking of the lock. This can be achieved in that a coupling element of the actuating mechanism 4, which serves for coupling with the lock, is no longer actuated, the handle part 3 thus executes an idle stroke or in that the handle part 3 is locked in its non-actuated position.

The bearing part 2 ( Fig. 7 . 8th ) has a base plate 6, a bearing housing 7 for supporting the locking mechanism 5, a cover 8 and means 9 for mounting the handle part 3.

The base plate 6 has a first, the handle part 3 facing base plate top 6a and one of the first base plate top 6a opposite, the handle part 3 facing away base plate top 6b. In addition, the elongated base plate 6 facing away from the bearing housing 7, the first plate end 6c and a this opposite, the bearing housing 7 facing the second plate end 6d.

The bearing housing 7 and the base plate 6 are preferably integrally formed and made of plastic. Furthermore, the bearing housing 7 adjoins the base plate 6 at the second plate end 6d. In addition, the bearing housing 7 extends away from the first plate top 6a. The bearing housing 7 is cup-shaped or cup-shaped or dome-shaped and has a circumferential, adjoining the base plate 6 peripheral wall 10 and a housing bottom 11. Opposite the housing bottom 11, the bearing housing 7 is open. The housing bottom 11 also has a first, circular cylindrical housing opening 12 for receiving a cylinder lock 13. In addition, the housing bottom 11 has a stepped shoulder 14 with an outer shoulder surface 15. In the region of the stepped shoulder 14, the housing bottom 11 has a second, in particular rectangular, housing opening 16. At the second housing opening 16 closes inside an annular, rectangular stop flange 17 at. The stop flange 17 is thus arranged within the bearing housing 7.

The bearing housing 7 also has an inner bearing bushing 18, which adjoins the first housing opening 12 and extends into the bearing housing 7. The bushing 18 thus extends away from the housing bottom 11 to the base plate 6. The bearing bush 18 has a bearing bush axis 19, which extends away from the housing bottom 11 on the base plate 6. In particular, the bearing bush axis 19 is perpendicular to the base plate 6. The bearing bush 18 thus has a first, housing bottom side bushing end 18a and an opposite, the housing bottom 11 facing away from the socket end 18b. The bushing 18 also has a bushing wall 20 with a bushing outer surface 21 and a Buchsenwandungsinnenfläche 22 and a Buchsenwandungsbodenfläche 32.

The Buchsenwandungsinnenfläche 22 has seen from the first housing opening 12 forth in the direction of the bearing bush axis 19 a first circular cylindrical inner surface portion 23, which serves to support a lock cylinder 24 of the cylinder lock 13. The first, circular cylindrical inner surface portion 23 is followed by a conical inner surface portion 25, which tapers in the direction of the bearing bush axis 19. At the conical inner surface portion 25, a second, circular cylindrical inner surface portion 26 connects. This passes via a first, planar annular surface 27 in a third, circular cylindrical inner surface portion 28 via. The third circular-cylindrical inner surface section 28 has a smaller diameter than the second, circular-cylindrical inner surface section 26. In addition, the third, circular-cylindrical inner surface section 28 merges via a second, planar annular surface 29 into a fourth, circular-cylindrical inner surface section 30. The fourth, circular-cylindrical inner surface portion 30 defines a passage opening 31.

The bushing bottom surface 32 connects to the bushing wall outer surface 21 at the second bushing end 18b. The Buchsenwandungsbodenfläche 32 has seen from the Buchsenwandungsaußenfläche 21 ago in the direction of the bearing bush axis 19, first an annular locking surface 33. The latching surface 33 thus directly adjoins the bottom wall outer surface 21. At the locking surface 33, a circular cylindrical bottom surface portion 34 connects. The circular-cylindrical bottom surface section 34 is adjoined by an annular, planar contact surface 35. The planar contact surface 35 then directly adjoins the fourth, circular-cylindrical inner surface section 30. In addition, the contact surface 35 is perpendicular to the bearing bush axis 19.

The latching surface 33 has two latching sections 36 which are located radially with respect to the bearing bush axis 19. The latching portions 36 each have two in relation to the bearing bush axis 19 in the circumferential direction adjacent latching recesses or latching recesses 37. The mutually adjacent locking recesses 37 are each a grid survey 38 into each other. The locking recesses 37 and grid elevations 38 are each formed by tapered wedge surfaces 39.

The bushing 18 also has a protruding from the locking surface 33 spring pin 40, which serves to support a torsion spring 41, which will be discussed in more detail below.

The bearing housing 7 also has a bearing sleeve 42, which has a bearing sleeve axis 43. The bearing sleeve axis 43 is coaxial with the bearing bush axis 19. In addition, the bearing sleeve 42 is arranged around the bearing bush 18 around. The bearing sleeve 42 thus surrounds the bearing bush 18. Between the bearing bush 18, in particular the bearing bush outer surface 21, and the bearing sleeve 42, in particular a bearing sleeve inner surface 44, an annular gap 45 is thus present. The annular gap 45 is bounded on the housing bottom 11 by an annular, in particular flat, stop surface 46. The bearing sleeve 42 likewise extends away from the housing bottom 11. As a result, the bearing sleeve 42 has a first, housing bottom end bearing sleeve end 42a and a second opposite, the housing bottom 11 facing away from the bearing sleeve end 42b.

In addition, the bearing sleeve 42 a plurality of circumferentially in relation to the bearing sleeve axis 43 adjacent arranged and spaced apart guide ribs 47. The guide ribs 47 adjoin the circular cylindrical bearing sleeve inner surface 44 and protrude radially inwardly from the latter. In addition, the guide ribs 47 extend from the first to the second bearing sleeve end 42a, 42b, ie over the entire length of the bearing sleeve 42.

As already explained above, the pull handle 1 according to the invention has a closing mechanism 5 with a cylinder lock 13 (FIG. Fig. 2 . 3 ). The cylinder lock 13 has, in a manner known per se, the lock cylinder 24 and a cylinder core 48 with spring-loaded platelet tumblers 49 arranged therein and a locking tumbler 50. The lock cylinder 24 has a cylinder axis 51, is preferably formed in two parts and has a first and a second cylinder part 24a, 24b. The cylinder axis 51 is coaxial with the bearing bush axis 19. The two cylinder parts 24a, 24b are pressed together. In addition, between the two cylinder parts 24a, 24b, a ring slot is formed, in which the Sperrzuhaltung 50 engages. As a result, the cylinder core 48 is mounted axially immovably in the lock cylinder 24. The lock cylinder 24 is also injected into the bearing housing 7, So stored in this immovable and non-rotatable. In this case, the lock cylinder 24 is disposed within the bearing bush 18 and abuts against the first circular cylindrical inner surface portion 23 and the conical inner surface portion 25.

The cylinder core 48 is arranged in a conventional manner within the lock cylinder 24. If no matching key is inserted into the cylinder core 48, the plate tumblers 49 are pressed by means of springs into grooves of the lock cylinder 24, so that the cylinder core 48 in the lock cylinder 24 can not be rotated about the cylinder axis 51. If a suitable key is introduced, the plate tumblers 49 are drawn into the cylinder core 48, so that the cylinder core 48 in the lock cylinder 24 can be rotated about the cylinder axis 51. This is known per se.

The locking mechanism 5 also has an adapter pin 52, a driving sleeve 53 and a locking sleeve 54.

In order to transmit or forward the rotational movement of the cylinder core 48, the adapter pin 52 (FIG. Fig. 11,12 ) available. The adapter pin 52 is preferably made of metal, in particular of zinc, and was produced in particular by means of die casting. The adapter pin 52 has a longitudinal extent in the direction of an adapter pin longitudinal axis 58, which is coaxial with the cylinder axis 51. In addition, the adapter pin 52 has an adapter pin head 59, an adapter pin collar 60 adjoining the adapter pin head 59, and an adapter pin shaft 61 adjoining the adapter pin collar 60. Thus, the adapter pin 52, as seen in the direction of the adapter pin longitudinal axis 58, has a head end or adapter pin drive end 52a and a foot end 52b opposite the head end 52a. The adapter pin head 59 has a head top 59a, which is expediently planar. In addition, the adapter pin head 59 has a circumferential, cylinder jacket-shaped head edge surface 62 and a top surface 59b opposite the head top side 59a and expediently planar. The head top side 59a and the head bottom side 59b are preferably perpendicular to the adapter pin longitudinal axis 58. Furthermore, the adapter pin head 59 has a drive slot 63 which protrudes from the head top side 59a into the adapter pin head 59. The drive slot 63 is used for coupling with the cylinder core 48. This has at its end facing the adapter pin 52 a drive pin 64 which engages positively in the drive slot 63.

The adapter pin collar 60 adjoins the head bottom side 59b of the adapter pin head 59 and has a circumferential, circular jacket-shaped collar edge surface 65 and a bottom side 60a opposite the head bottom side 59b and expediently planar. The collar lower side 60a is preferably perpendicular to the cylinder axis 51 and Adapter pin axis 58. The diameter of the collar edge surface 65 is less than the diameter of the Kopfrandfläche 62nd

The adapter pin shaft 61 is formed circular cylindrical and forms at its end facing away from the adapter pin collar 60 end 52 b. In addition, the adapter pin shaft 61 has a circular-cylindrical shaft outer surface 61a, which preferably tapers slightly over a shoulder at the foot end 52b opposite the head end 52a. The diameter of the shaft outer surface 61a is less than the diameter of the collar edge surface 65. At the foot end 52b, the adapter pin shaft 61 has a, expediently planar and perpendicular to the adapter pin longitudinal axis 58 end face 66.

In addition, the adapter pin 52 has two output ribs 67 radially opposite each other in relation to the adapter pin longitudinal axis 58. The output ribs 67 connect directly to the collar lower side 60a and extend radially as well as in the longitudinal direction of the adapter pin longitudinal axis 58. They are thus circular cylindrical tube segments. The output ribs 67 protrude from the adapter pin shaft 61 in the radial direction. The output ribs 67 have a circular-cylindrical rib outer surface 68, whose diameter preferably corresponds to the diameter of the collar edge surface 65. The output ribs 67 preferably do not extend over the entire length of the adapter pin shaft 61. As a result, they each have a rib end face 69 on their end facing away from the adapter pin collar 60. The rib end surface 69 is preferably planar in each case and perpendicular to the adapter pin longitudinal axis 58. In addition, the output ribs 67 each have two ribs 70 which radially delimit the output ribs 67, preferably flat surfaces. The rib edges 70 extend parallel to the adapter pin longitudinal axis 58.

The driving sleeve or driving bushing 53 (FIG. Fig. 13,14 ) is used to transmit the rotational movement of the adapter pin 52 on the detent sleeve 54. It is preferably made of metal, in particular zinc, and was produced in particular by means of die casting. The driver sleeve 53 has a longitudinal extent in the direction of a Mitnehmerhülsenlängsachse 71, which is coaxial with the adapter pin longitudinal axis 58. In addition, the drive sleeve 53 has a head disk 72 and a tubular or sleeve-shaped sleeve shaft 73 adjoining the head disk 72. The head disk 72 has a disk top side 72a and a disk underside 72b lying opposite thereto. The disc upper side 72a and the disc lower side 72b are each planar and perpendicular to the Mitnehmerhülsenlängsachse 71. The sleeve shaft 73 connects to the disc lower side 72b and extends away from this. In addition, the driving sleeve 53 has a through the driving sleeve 53 in the direction of the Mitnehmerhülsenlängsachse 71 continuous sleeve recess 74. The cross-sectional shape of the sleeve recess 74 corresponds to the cross-sectional shape of the adapter pin shaft 61 in the region of the output ribs 67.

The sleeve shaft 73 has a tubular shaft wall 75 with a skirt wall outer surface 75b and a skirt wall inner surface 75a. Since the skirt wall inner surface 75a limits the sleeve recess 74, the course of the skirt wall inner surface 75a likewise corresponds to the cross-sectional shape of the adapter pin shaft 61 in the area of the output ribs 67. The skirt wall outer surface 75b has two first guide surfaces 78 radially opposite one another relative to the drive sleeve longitudinal axis 71. The first guide surfaces 78 are formed circular-cylindrical surface segment-shaped. They are thus rotationally symmetrical to Mitnehmerhülsenlängsachse 71 and form segments of an outer circumferential surface of a circular cylinder. Furthermore, the shaft outer wall surface 75b has two guide surfaces 79 which are likewise radially opposite one another in relation to the driver sleeve longitudinal axis 71. The second guide surfaces 79 are also formed circular cylindrical surface segment. They are therefore also rotationally symmetrical to Mitnehmerhülsenlängsachse 71 formed. However, the diameter of the second guide surfaces 79 is greater than the diameter of the first guide surfaces 78. As a result, the second guide surfaces 79 are offset radially outward relative to the first guide surfaces 78. In this case, the first guide surfaces 78 are arranged in the circumferential direction between the second guide surfaces 79. Between the first and second guide surfaces 78, 79 there is in each case an actuating surface 80a, b, via which the guide surfaces 78, 79 merge into one another. Overall, four actuating surfaces 80a, b, namely two first actuating surfaces 80a and two second actuating surfaces 80b, are thus present. The first actuating surfaces 80a are for locking, the second actuating surfaces 80b serve to unlock, which will be discussed in more detail below. The first actuating surfaces 80a extend in a locking direction 202 (FIG. Fig. 4 ; 13 ) seen from one of the first guide surfaces 78 to the adjacent thereto, outwardly offset, the second guide surface 79. The second actuating surfaces 80b extending in the locking direction 202 extending from one of the second guide surfaces 79 to the adjacent thereto, inwardly offset, first Guide surface 78. In the locking direction 202 seen here means that the shaft outer wall surface 75b in locking direction 202 is traveled. The preferably planar actuating surfaces 80a, b also extend in each case in the radial direction and parallel with respect to the driver sleeve longitudinal axis 71.

The sleeve shaft 73 of the driver sleeve 53 also has a shaft end face 81, which is opposite to the head disk 72 and preferably planar. The shank end surface 81 is preferably perpendicular to the Mitnehmerhülsenlängsachse 71. In addition, the driving sleeve 53 has a spring pin 82 which protrudes from the disc lower side 72b and is spaced from the Schambwandungsaußenfläche 75b.

The locking sleeve 54 ( Fig. 15-17 ) serves to transmit the rotational movement of the driving sleeve 53 on a coupling sleeve 55 of the actuating mechanism 4. The detent sleeve 54 has a Rasthülsenwandung 83 and a latching sleeve axis 84 which is coaxial with the cylinder axis 51. The tubular Rasthülsenwandung 83 has a circular cylindrical Wandungsinnenfläche 85 and a circular cylindrical Wandungsaußenfläche 86. The wall inner surface 85 delimits a recess 87 passing through the latching sleeve 54 in the direction of the latching sleeve axis 84. The diameter of the inner wall surface 85 corresponds to the diameter of the second guide surfaces 79 of the driving sleeve 53. In addition, the sleeve wall 83 has a first, annular and preferably planar, walled end surface 83a and 83b a second, annular and preferably planar, Wandungsendfläche 83b. Furthermore, the latching sleeve 54 has a collar 88. The annular collar 88 adjoins the wall inner surface 85 and extends radially inwardly toward the latch sleeve axis 84. The annular collar 88 has a first annular collar surface 88a facing the first wall end surface 83a and a second annular collar surface 88b facing the second circumferential wall surface 83b. In addition, the annular collar 88 has a circular-cylindrical ring inner surface 89. The annular collar 88 is disposed, preferably substantially centrally, between the first and second wall end surfaces 83a, 83b.

The locking sleeve 54 also has two latching arms 90 which are integrally formed on the wall outer surface 86 and project from this. The latching arms 90 have a longitudinal extent parallel to the latching sleeve axis 84. The two latching arms 90 are arranged radially with respect to the latching sleeve axis 84 opposite one another. In addition, in the region of the second wall end surface 83b, the latching arms 90 adjoin the outer wall surface 86 and extend up to and beyond the first wall end surface 83a. In addition, the two latching arms 90 each have two mutually parallel sliding surfaces 91. The sliding surfaces 91 are each formed planar and extend parallel to the latching sleeve axis 84. Preferably, all four sliding surfaces 91 are parallel to each other. The sliding surfaces 91 are preferably perpendicular to the wall end surfaces 83a, 83b. At their free ends, the locking arms 90 also each have a latching nose 92. The latching nose 92 has two wedge surfaces 93, which taper towards each other and merge into one another via a latching edge 93a. At their opposite end of the detent 92, the locking arms 90 each have a stop surface 98.

The locking sleeve 54 also has two radially opposite drive ribs 94. The drive ribs 94 connect directly to the Wandinneninnenfläche 85 and extend radially and in the longitudinal direction of the latch sleeve axis 84. They are thus Kreisrohrrohrsegmente. The drive ribs 94 project from the wall inner surface 85 in the radial direction inwards. In addition, the drive ribs 94 close to the first annular collar surface 88a and extend to the first Wandendendfläche 83a and close flush with this. The drive ribs 94 have a circular-cylindrical rib inner surface 95 whose diameter corresponds to the diameter of the first guide surfaces 78. In addition, the drive ribs 94 each have two drive ribs 94 radially delimiting, preferably planar, first and second rib edges 96a, b. The rib edges 96a, b extend parallel to the catch axis 84 and in the radial direction with respect to the catch sleeve axis 84. Overall, there are thus four rib edges 96a, b, namely two first rib edges 96a and two second rib edges 96b. The first rib edges 96a are for locking, the second rib edges 96b serve to unlock, which will be discussed in more detail below. The first rib edge 96a is in each case the first rib edge 96a of the drive rib 94 as viewed in the locking direction 202, the second rib edge 96b of the drive rib 94 is arranged downstream of the first rib edge 96a of the drive rib 94 in the closing direction 202.

In the assembled state, the sleeve shank 73 of the driver sleeve 53 is arranged in the recess 87 in such a way that the shank end face 81 rests on the first annular collar surface 88a. In addition, the second guide surfaces 79 of the driver sleeve 53 abut against the inner wall surface 85 of the latching sleeve 54. And the first guide surfaces 78 of the drive sleeve 53 abut against the rib inner surfaces 95 of the drive ribs 94. And the actuating surfaces 80a, b of the driving sleeve 53 are arranged between the rib edges 96a, b of the drive ribs 94 in the circumferential direction with respect to the latching sleeve axis 84.

The distance in the circumferential direction of the rib edges 96a, b from each other in the circumferential direction adjacent drive ribs 94 is greater than the extension of the second guide surfaces 79 in the circumferential direction. And the distance in the circumferential direction of the rib edges 96a, b of a drive rib 94 is smaller than the extent of the first guide surfaces 78 in the circumferential direction. As a result, there is a play or freewheel with respect to the rotational movement about the cylinder axis 51 between the driving sleeve 53 and the locking sleeve 54. That is, the locking sleeve 54 and the driving sleeve 53 are rotatable by a limited amount relative to each other about the cylinder axis 51, which will be discussed in more detail below. In particular, the freewheel, ie the amount by which the driver sleeve 53 and the detent sleeve 54 are rotatable relative to one another, is 40 to 50 °, preferably 45 °.

When installed, the locking lugs 92 are arranged in one of the locking recesses 37, which will also be discussed in more detail below.

As already explained above, the pull handle 1 according to the invention also has an actuating mechanism 4 for actuating a lock. The actuating mechanism 4 has the coupling sleeve 55, a coupling pin 56 and a driving fork 57.

At the first coupling sleeve end 55a, the coupling sleeve wall 100 has a first, preferably planar, annular end face 101, which is preferably perpendicular to the coupling sleeve longitudinal axis 99. At the second coupling sleeve end 55b, the coupling sleeve wall 100 has a second, preferably planar, annular end face 102, which is preferably likewise perpendicular to the coupling sleeve longitudinal axis 99. In addition, the coupling sleeve wall 100, viewed from the first coupling sleeve end 55a in the direction of the coupling sleeve longitudinal axis 99, initially has a circular-cylindrical bearing section 103. The circular-cylindrical bearing section 103 is adjoined by a transition section 104. In the region of the transition section 104, the coupling sleeve wall 100 tapers toward the coupling sleeve longitudinal axis 99. That is, the outer diameter and the inner diameter of the coupling sleeve wall 100 decrease. At the transition portion 104, a circular cylindrical guide portion 105 connects.

The coupling sleeve 55 also has two preferably mutually radially with respect to the coupling sleeve longitudinal axis 99 coupling pin 106.

The window 111 is arranged in the circumferential direction of the coupling sleeve 55 between the two guide slots 108. In addition, the window 111 also begins in the transition section 104 and extends into the guide section 105. However, the window 111 does not extend as far as the guide slots 108 into the guide region 105. The window 111 serves to receive the two spring pins 40, 82.

Furthermore, the coupling sleeve 55 has a plurality of ribs 112 arranged distributed in the circumferential direction of the coupling sleeve 55.

The second rib end 112b is located at the height of the first slot end edges 110a. In addition, each two ribs 112 are arranged in the direction of the coupling sleeve longitudinal axis 99 aligned with the guide edges 109 of the guide slots 108. These ribs 112 form guide ribs 115 which serve to guide the coupling sleeve 55 through the latching sleeve 54. The two guide ribs 115 each have a planar guide surface 116. The guide surfaces 116 of the mutually corresponding guide ribs 15 face each other and parallel to each other.

At its second coupling sleeve end 55b, the coupling sleeve 55 also has an annular bearing shoulder 117 protruding into the interior of the coupling sleeve 55.

• Im zusammengebauten Zustand des Ziehgriffes 1 (Fig. 2 und 3) ist der Deckel 8 mit dem Lagergehäuse 7 fest, also unverdrehbar und unverschieblich, aber lösbar verbunden, insbesondere verschraubt. Die dazu verwendeten Schrauben (nicht dargestellt) durchgreifen dabei die vier Verschraubungsaussparungen 130c der Deckelplatte 130 des Deckels 8 und sind in Anschraubdome 201 mit Innengewinde eingeschraubt, die an den Gehäuseboden 11 des Lagergehäuses 7 angeformt sind. Die Deckelplatte 130 des Deckels 8 deckt bzw. schließt das Lagergehäuse 7 an dessen offenem Ende ab. Dabei schließt sich die Deckelplatte 130 an das zweite Plattenende 6d der Grundplatte 6 an und ist in Verlängerung derer angeordnet. Die innere Plattenoberseite 130a der Deckelplatte 130 ist dem Lagergehäuse 7 zugewandt. Infolgedessen ist die Führungsbuchse 131 des Deckels 8 außerhalb des Lagergehäuses 7 angeordnet. Insbesondere weist die Führungsbuchse 131 vom Lagergehäuse 7 weg.

The following is an explanation of the assembled pull handle 1:

• In the assembled state of the pull handle 1 ( Fig. 2 and 3 ), the lid 8 with the bearing housing 7 fixed, so non-rotatable and immovable, but releasably connected, in particular screwed. The screws used for this purpose (not shown) pass through the four Verschraubungsaussparungen 130c of the cover plate 130 of the lid 8 and are screwed into Anschraubdome 201 with internal thread, which are integrally formed on the housing bottom 11 of the bearing housing 7. The cover plate 130 of the cover 8 covers or closes off the bearing housing 7 at its open end. In this case, the cover plate 130 connects to the second plate end 6 d of the base plate 6 and is arranged in extension of those. The inner plate top side 130 a of the cover plate 130 faces the bearing housing 7. As a result, the guide bushing 131 of the lid 8 is disposed outside of the bearing housing 7. In particular, the guide bushing 131 away from the bearing housing 7.

As already explained above, the lock cylinder 24 is mounted in the bearing housing 7, in particular the bearing bush 18, immovable and non-rotatable. Preferably, the lock cylinder is injected into the bearing bush 18. In this case, the lock cylinder 24 is located on the first circular cylindrical inner surface portion 23 and the conical inner surface portion 25 of the Buchsenwandungsinnenfläche 22 of the bearing bush 18 at. The cylinder axis 51 is coaxial with the bearing bush axis 19th

The cylinder core 48 is, as also explained above, axially immovable, but rotatable after insertion of a suitable key about the cylinder axis 51, mounted in the lock cylinder 24.

The adapter pin head 59 of the adapter pin 52 is seated with the head lower side 59b on the second annular surface 29 of the Buchsenwandungsinnenfläche 22 of the bearing bush 18. As a result, the adapter pin head 59 is clamped in the axial direction between the second annular surface 29 and the cylinder core 48. The head edge surface 62 of the adapter pin head 59 of the adapter pin 52 is disposed within the third circular cylindrical inner surface portion 28 of the Buchsenwandungsinnenfläche 22 of the bearing bush 18. And the adapter pin collar 60 of the adapter pin 52 is positively arranged within the fourth circular cylindrical inner surface portion 30 of the female wall inner surface 22 of the bearing bush 18 and within the through hole 31 of the bearing bush 18. The adapter pin 52 is thus immovably mounted in the axial direction but about the adapter pin longitudinal axis 58 and the cylinder axis 51 rotatably in the bearing bush 18. The drive pin 64 of the cylinder core 48 also engages positively in the drive slot 63 of the adapter pin 52 a. As a result, the adapter pin 52 is non-rotatably connected to the cylinder core 48 about the cylinder axis 51. Respectively. the adapter pin 52 is rotatably drivable with the cylinder core 48 about the cylinder axis 51 in connection.

In addition, the adapter pin 52 passes through the passage opening 31 of the bearing bush 18. The output ribs 67 and the adapter pin shaft 61 of the Adaper pin 52 are thus arranged outside of the bearing bush 18. The adapter pin head 59 and the adapter pin collar 60 are disposed within the bushing 18.

With the adapter pin 52, the driving sleeve 53 is non-rotatably connected to the cylinder axis 51 in connection. Respectively. the driving sleeve 53 is connected to the adapter pin 52 about the cylinder axis 51 rotatably driven in connection. Respectively. the driver sleeve 53 is connected via the adapter pin 52 with the cylinder core 48 about the cylinder axis 51 rotatably driven in connection. The adapter pin 52 thus serves to transmit the rotational movement of the cylinder core 48 without delay or freewheel on the driver sleeve 53. For this purpose, the adapter pin shaft 61 of the adapter pin 52 in the region of the output ribs 67 within the sleeve recess 74 of the driving sleeve 53 is arranged. The Schaftwandungsinnenfläche 75a of the shaft wall 75 of the drive sleeve 53 surrounds the adapter pin shaft 61 and the output ribs 67 positively. The remaining part of the adapter pin shaft 61 projects out of the driving sleeve 53. The upper side 72a of the disk 72 of the driving sleeve 53 also abuts against the contact surface 35 of the bushing wall bottom surface 32 of the bearing bushing 18.

The driving sleeve 53 is also in communication with the torsion spring 41. The torsion spring 41 is biased in the starting position or 0-position of the driving sleeve 53. This starting position corresponds to the position of the driving sleeve 53 at the starting position or 0-position of the cylinder core 48. For this purpose, the torsion spring 41 is arranged around the shaft outer wall surface 75b of the shaft wall 75 of the driving sleeve 53 and is supported at one end on the spring pin 82 of the driving sleeve 53 and at the other end the spring pin 40 of the bearing bush 18 from. If the driving sleeve 53 is rotated about the cylinder axis 51, no matter in which direction, the torsion spring 41 is further tensioned and drives the driving sleeve 53 in each case counter to the deflection direction back to its starting position. That is, the torsion spring 41 has the tendency to rotate the drive sleeve 53 against the respective deflection direction. As a result, the torsion spring 41, the drive sleeve 53 drives after deflection against the respective deflection relative to the bearing housing 7.

The locking sleeve 54 is arranged with the Rasthülsenwandung 83 to the sleeve shaft 73 of the driving sleeve 53. In this case, the second guide surfaces 79 of the driver sleeve 53 abut against the inner wall surface 85 of the latching sleeve wall 83. And the first guide surfaces 78 of the drive sleeve 53 abut against the rib inner surfaces 95 of the drive ribs 94 of the latching sleeve 54. The shank end surface 81 of the sleeve shaft 73 of the driving sleeve 53 also bears against the first annular collar surface 88a of the annular collar 88 of the locking sleeve 54. And the adapter pin 52 passes through the latching sleeve wall 83 and protrudes beyond the second wall end face 83b, projects out of the latching sleeve 54.

The first actuating surfaces 80a of the driver sleeve 53 also abut against the first rib edges 96a of the drive ribs 94 of the latching sleeve 54. As a result, the latching sleeve 54 is rotatably drivable with the driving sleeve 53 about the cylinder axis 51 in the locking direction 202. A rotational movement of the driving sleeve 53 in the locking direction 202 is transmitted directly and immediately, ie without delay or play on the locking sleeve 54.

In addition, the latching lugs 92 of the latching arms 90 of the latching sleeve 54 are arranged in each case a latching recess 37, engaged in this. This is effected by a second compression spring 97. The second compression spring 97 is arranged around the adapter pin shaft 61 around and is supported at one end to the second, the drive sleeve 53 facing away from the annular collar surface 88b and the other end on a support disk 203 from. The support disc 203 is disposed adjacent to the foot end 52b of the adapter pin 52 about the adapter pin shaft 61 around and connected to this axially immovable. The second compression spring 97 urges the detent sleeve 54 in the direction of the bearing bushing 18. The detent sleeve 54 is consequently drivably connected to the second compression spring 97 in an actuating direction 204 parallel to the cylinder axis 51. As a result, the latching lugs 92 of the latching sleeve 54 are pressed into the latching recesses 37. Due to this, the detent sleeve 54 can be rotated about the cylinder axis 51 only against the force of the second compression spring 97.

In the non-actuated state ( Fig. 2 ), So when the handle part 3 is not actuated, the locking sleeve 54 is also arranged in the bearing portion 103 of the coupling sleeve 55. The two locking arms 90 of the locking sleeve 54 are arranged between each two ribs 112 of the coupling sleeve 55. The sliding surfaces 91 of the latching arms 90 abut against the ribs 112. In this case, the latching sleeve 54 is arranged in the region of the first rib ends 112a of the ribs 112. The coupling sleeve 55 is thus connected to the latching sleeve 54 around the cylinder axis 51 in an unrotatable manner. Respectively. the coupling sleeve 55 is rotatably driven with the locking sleeve 54 about the cylinder axis 51 in connection. However, the coupling sleeve 55 is displaceable in the axial direction, ie parallel to the cylinder axis 51, by a limited amount relative to the latching sleeve 54.

The coupling sleeve 55 is displaceable in a direction parallel to the cylinder axis 51 and mounted rotatably about the cylinder axis 51 in the bearing part 2, in particular the bearing housing 7. For this purpose, the bearing portion 103 of the coupling sleeve 55 is guided in the bearing sleeve 42 of the bearing housing 7. In particular, the outer wall surface 100b of the coupling sleeve wall 100 rests against the guide ribs 47 in the region of the bearing section 103. In addition, the guide portion 105 of the coupling sleeve 55 is disposed within the guide bush 131 of the lid 8. In particular, the outer wall surface 100b of the coupling sleeve wall 100 rests against the inner wall surface 133a of the guide sleeve wall 133 in the region of the guide section 105. The coupling sleeve 55 is thus also displaceable in the cover 8 in a direction parallel to the cylinder axis 51 and rotatably supported about the cylinder axis 51. In the non-actuated starting position, the second end face 102 of the coupling sleeve wall 100 bears against the two stop faces 135 of the guide bush 131 of the cover 8. The coupling sleeve 55 thus does not protrude out of the cover 8.

In this non-actuated position, the coupling sleeve 55 is pressed by the first compression spring 114. The first compression spring 114 is arranged around the bearing bushing 18, in particular bears against the bushing wall outer surface 21. The first compression spring 114 is thus arranged in the annular gap 45. At one end, the first compression spring 114 is supported on the stop surface 46 of the housing bottom 11 from. At the other end, the first compression spring 114 is supported on the ribs 112, in particular on the first rib end 112a. For this purpose, the first compression spring 114 is arranged in the receiving troughs 113 of the ribs 112. As a result, pushes the first compression spring 114, the coupling sleeve 55 away from the housing bottom 11, on the lid 8 to its non-actuated position. The coupling sleeve 55 is therefore connected to the first compression spring 114 against the actuation direction 204 drivable in connection.

The coupling pin 56 is immovable in the axial direction parallel to the coupling pin longitudinal axis 120, but freely rotatable about the coupling pin longitudinal axis 120 in the coupling sleeve 55. In particular, the coupling pin 56 is arranged with the coupling pin head 121 and the coupling pin collar 122 within the guide portion 105 of the coupling sleeve 55. For this purpose, the coupling pin 56 rests with the collar lower side 126 on the first shoulder surface 118a of the bearing shoulder 117 of the coupling sleeve 55. In addition, a clamping ring 205 is provided which secures the coupling pin 56 in the axial direction. The coupling pin shaft 123 projects out of the coupling sleeve 55 at the second coupling sleeve end 55b. In addition, the coupling pin 56 protrudes in the non-actuated state of the handle part 3 (FIG. Fig. 2 ) Also from the guide bush 131 at the second end of the socket 131b, ie from the pull handle housing 1a, out. Thereby, the coupling pin 56 can be connected to the operating mechanism of a lock. The coupling pin 56 thus serves for connection to coupling elements of the lock mechanism which are arranged outside of the pull handle housing 1 a.

As already explained above, the driving fork 57 is formed in two parts. In the assembled state, however, the operating part 138 and the coupling part 139 are firmly connected. In addition, the driving fork 57 is firmly connected to the handle part 3. For this purpose, four fastening screws 76 are present, which pass through the Verschraubungsaussparungen 147c and are screwed into the Anschraubdome 169. The connecting shaft 148 then projects from the bottom wall 166 of the actuating region 155 of the grip part 3. In addition, the connecting shaft 148 passes through the second housing opening 16. In this case, the seal 151 bears against the outer shoulder surface 15 of the stepped shoulder 14 of the bearing housing 7.

The two fork arms 140 of the Mitnehmergabel 57 are also within the bearing housing 7 and the outside around the coupling sleeve 55, in particular the bearing portion 103, arranged around, engage around the coupling sleeve 55. The coupling sleeve 55 is thus arranged in the receiving region 141. In this case, the actuating projections 143 of the fork arms 140 abut respectively on the coupling surfaces 107 of one of the coupling pins 106 of the coupling sleeve 55. As a result, the coupling sleeve 55 is driven via the driving fork 57 with the handle part 3 in the actuating direction 204 drivable in connection.

As already explained, the grip part 3 is pivotably connected to the bearing part 2, in particular the base plate 6, about the pivot axis 140 ( Fig. 2 . 3 and 34 ). For this purpose, the bearing 188 with the bottom wall 158 of the bearing portion 156 of the handle part 3 is firmly connected, in particular screwed. Mounting screws 206 pass through the recesses 190 of the bearing 188 and are screwed into the Anschraubdome 165 of the bearing shell 164. In the bearing recess 192 of the bearing 188 of the axle 193 is arranged. In addition, the axle pin 193 is arranged in the two bearing recesses 177 of the bearing arms 173 of the bearing block 171. The bearing 188 is arranged between the two bearing arms 173. The bearing block 171 is also firmly connected to the base plate 6. For this purpose, a fastening screw (not shown) is present, which passes through a recess in the base plate 6 and is screwed into an internal thread of the mounting block 172. The two bearing arms 173 thus stand out from the base plate 6. The axle 193 is completely within the handle part 3, in particular of the bearing portion 156 of the handle part 3, arranged.

The threaded sleeve 174 of the bearing block 171 engages through a recess in the bottom plate 6, so that it is accessible from the outside, ie from the second bottom plate top side 6b or open to the second bottom plate top side 6b. Thereby, the bearing block 171 (not shown) by means of another fastening screw to a vehicle door made of metal, glass or plastic can be attached. The fastening screw passes through an opening in the vehicle door. In addition, a rubber pad as a seal and a Unterfütterungsblech are arranged inside the door in a conventional manner between the vehicle door and the pull handle 1, which are also penetrated by the mounting screw. The relining plate serves for force distribution. In addition, the door lock is usually attached to the relining plate.

As a result, at least a part of the forces, the leaf spring 179 is transmitted to the vehicle door. The base plate 6 is thus relieved. In addition, the forces that arise when pulling on the handle part 3, at least partially directly, that is not passed over the base plate 6, on the other fastening screw to the vehicle door.

Furthermore, the leaf spring 179 is supported by the end of the connecting region 187 on the spring tensioner 194, in particular of the first main body top side 195a. For this purpose, the spring tensioner 194 is arranged with the strip 200 in the bearing groove 161 of the bearing portion 156 of the grip part 3. In addition, the ribs 160 of the storage area 156 are arranged in the slots 197 of the spring compressor 197. The first main body top side 195a points toward the bottom wall 158 of the storage area 156. Fixing screws 207 pass through the recesses 196 of the spring tensioner 194 and are screwed into the Anschraubdome 163. The spring tensioner 194 is thus fixed, ie non-displaceable and non-rotatable, connected to the storage area 156.

Furthermore, the leaf spring 179 is supported on the two bearing arms 143 in the region of the two spring arm ends 184. In particular, the spring arm ends 184 are each arranged in one of the two spring receiving slots 178. In addition, the Abstützbügel 186 of the leaf spring 179 abut against the support edges 181 a. As a result, the handle part 3 is connected to the leaf spring 179 counter to a handle actuating direction 208 about the pivot axis 170 rotatably driven in connection. The leaf spring 179 pushes the handle part 3 in its non-actuated position.

If the pull handle 1 is attached to the vehicle door or flap, the guide bush 131 with the threaded bushing 136 arranged therearound passes through an opening in the vehicle door. In addition, a nut is screwed onto the threaded bushing 136, so that the pulling handle 1 is clamped to the vehicle door. In addition, as described above, between the nut and the vehicle door, a rubber seal and a relining plate are provided, which are also penetrated by the threaded bushing 136. This type of attachment is particularly well suited for attachment to a glass door. Because it is only a single large opening in the glass plate necessary, not several. But creating openings in glass plates is not easy and critical, so that a single large opening is very beneficial.

• Um die Schlossmechanik des jeweiligen Schlosses auszulösen, wird von einer Bedienperson am Griffteil 3 gezogen, so dass dieses in die Griffbetätigungsrichtung 208 (Fig. 2) gegen die Kraft der Blattfeder 179 relativ zum Lagerteil 2 um die Schwenkachse 170 von seiner unbetätigten (Fig. 2) in seine betätigte Stellung (Fig. 3) verschwenkt wird. Dadurch wird auch die Mitnehmergabel 57 in Griffbetätigungsrichtung 208 verschwenkt. Dabei bewegen sich die Betätigungsvorsprünge 143 der Gabelarme 140 auf die Bodenwandung 11 des Lagergehäuses 7 zu. Die Betätigungsvorsprünge 143 bewegen sich also anteilsmäßig in Betätigungsrichtung 204. Da die Betätigungsvorsprünge 143 an den Kopplungsflächen 107 der Kopplungszapfen 106 anliegen, wird die Kopplungshülse 55 von den Betätigungsvorsprüngen 143 in die Betätigungsrichtung 204 mitgenommen. Die Betätigungsvorsprünge 143 gleiten dabei an den Kopplungsflächen 107 der Kopplungszapfen 106 entlang. Die Drehbewegung der Mitnehmergabel 57 bewirkt somit eine lineare Bewegung der Kopplungshülse 55 in eine zur Zylinderachse 51 parallele Betätigungsrichtung 204 gegen die Kraft der ersten Druckfeder 114. Die Zylinderachse 51 stellt somit eine Betätigungsachse 209 des Betätigungsmechanismus 4 dar bzw. ist koaxial zu dieser. Der Lagerbereich 103 der Kopplungshülse 55 gleitet dabei in die Lagerhülse 42 hinein. Die Kopplungshülse 55 kann soweit in Betätigungsrichtung 204 relativ zum Lagergehäuse 7 verschoben werden, bis die erste Endfläche 101 der Kopplungshülse 55 an der Anschlagfläche 46 des Gehäusebodens 11 anschlägt.

The mode of operation of the pull handle according to the invention will now be explained in more detail below:

• To trigger the lock mechanism of the respective lock is pulled by an operator on the handle part 3, so that this in the handle actuating direction 208 (FIG. Fig. 2 ) against the force of the leaf spring 179 relative to the bearing part 2 about the pivot axis 170 of its unactuated ( Fig. 2 ) in its actuated position ( Fig. 3 ) is pivoted. As a result, the driver fork 57 is also pivoted in the handle actuating direction 208. In this case, the actuating projections 143 of the fork arms 140 move toward the bottom wall 11 of the bearing housing 7. The actuating projections 143 thus move proportionately in the actuating direction 204. Since the actuating projections 143 abut against the coupling surfaces 107 of the coupling pins 106, the coupling sleeve 55 is carried along by the actuating projections 143 in the actuating direction 204. The actuating projections 143 slide along the coupling surfaces 107 of the coupling pins 106. The rotational movement of the driving fork 57 thus causes a linear movement of the coupling sleeve 55 in a direction parallel to the cylinder axis 51 actuating direction 204 against the force of the first compression spring 114. The cylinder axis 51 thus represents an actuating axis 209 of the actuating mechanism 4 is coaxial with this. The storage area 103 of the coupling sleeve 55 slides while in the bearing sleeve 42 inside. The coupling sleeve 55 can be displaced so far in the actuating direction 204 relative to the bearing housing 7 until the first end face 101 of the coupling sleeve 55 abuts the stop surface 46 of the housing bottom 11.

During the movement of the coupling sleeve 55, the latching arms 90 of the latching sleeve 54 slide in the guide slots 108 of the coupling sleeve 55. In the actuated state of the handle part 3, the latching arms 54 are arranged in the guide section 105 of the coupling sleeve 55. The stop surfaces 98 of the latching arms 90 preferably abut against the second slot end edges 110b.

Since the coupling pin 56 with the coupling sleeve 55 is immovably in communication, this is taken from the coupling sleeve 55 and moved in the direction of actuation 204. The linear movement of the coupling pin 56 then leads to an actuation of the respective lock mechanism.

Upon release of the handle part 3 pivots this, driven by the force of the leaf spring 179, opposite to the handle actuating direction 208 in its non-actuated position ( Fig. 2 ) back. Also, the coupling sleeve 55 moves, driven by the force of the first compression spring 114, against the actuating direction 204 back to its non-actuated position.

The above-described operation applies to unlocked or unlocked pull handle 1, that is, if the locking mechanism, in particular the cylinder lock 13, in its non-locking or unlocked position or starting position. If now the pull handle 1 is to be locked, a suitable key is inserted into the cylinder core 48 by the operator, so that the platelet tumblers 49 are retracted. Subsequently, the key is placed in the lock 202 ( Fig. 4 ) is rotated about the cylinder axis 51, which causes rotation of the cylinder core 48 in the locking direction 202. A rotation of the cylinder core 48 causes a rotation of Adaperstifts 52 about the cylinder axis 51 in the locking direction 202. The Adaperstift 52 in turn drives the drive sleeve 53 without delay in the locking direction 202 at. Since the first actuating surfaces 80a of the driving sleeve 53 abut against the first rib edges 96a of the drive ribs 94 of the detent sleeve 54, the detent sleeve 54 is also driven without delay by the entraining sleeve 53 in the locking direction 202. The detents 92 of the detent sleeve 55 are pressed against the force of the second compression spring 97 out of the detent recesses 37 and engage after rotation in the adjacent detent recesses 37 a.

The cylinder core 48, the adapter pin 52, the driving sleeve 53 and the locking sleeve 54 are then in their closed position.

The locking sleeve 55, in turn, drives the coupling sleeve 55 into the locking direction 202 without delay. The coupling pins 106 are rotated so that they no longer are arranged in the direction of the cylinder axis 51 in alignment with the actuating projections 143 of the fork arms 140 ( Fig. 5 ). As a result, the driving fork 57 and the coupling sleeve 55 are mechanically decoupled from each other. The coupling sleeve 55 is in its decoupled position. A rotational movement of the driving fork 57 in the handle actuating direction 208 causes no movement of the coupling sleeve 55 more. There is only one Leerhub the handle part 3 instead. The lock mechanism is not actuated.

If the key is released, the driving sleeve 53, driven by the force of the torsion spring 41, rotates counter to the locking direction 202 in its Mitnehmerhülsenausgangsstellung. The drive sleeve 53 also drives the adapter pin 52 and above the cylinder core 48 against the locking 202 at. These also return to their respective starting position.

However, the locking sleeve 54 is not entrained by the driving sleeve 53 in the locking direction 202, due to the freewheel described above between the locking sleeve 54 and the driving sleeve 53. In particular, the driver sleeve 53 can be rotated relative to the locking sleeve 54 against the locking direction 202 until the second actuating surfaces 80b of the driver sleeve 53 abut against the second rib edges 96b of the drive ribs 94 of the detent sleeve 54.

The detent sleeve 54 and the coupling sleeve 55 thus remain in their closed position or decoupled position even after releasing the key. If the key is then inserted again and rotated in the locking direction 202, the cylinder core 48, the adapter pin 52 and the driving sleeve 53 are rotated in the locking direction 202, but the locking sleeve 54 and the coupling sleeve 55 are not moved again. The driver sleeve 53 pivots only relative to the detent sleeve 54 until the first actuating surfaces 80a of the driver sleeve 53 rest against the first rib edges 96a of the drive ribs 94 of the detent sleeve 54 again.

If now again unlocked or unlocked or coupled, the key is rotated by the operator against the lock-202. As a result, the cylinder core 48, the adapter pin 52 and the driving sleeve 53 are pivoted against the locking direction 202. Since the second actuating surfaces 80b of the driver sleeve 53 bear against the second rib edges 96b of the drive ribs 94 of the latching sleeve 54, the latching sleeve 54 is likewise driven without delay by the driver sleeve 53 against the locking direction 202. The locking lugs 92 of the locking sleeve 55 are again pressed against the force of the second compression spring 97 out of the locking recesses 37 and engage after rotation in the adjacent thereto detent recesses 37 a. The coupling sleeve 55 is taken from the locking sleeve 54 and pivoted in its coupled position. To Letting go of the key, the driving sleeve 53, driven by the force of the torsion spring 41, rotates in the locking direction 202 in its Mitnehmerhülsenausgangsstellung. The driving sleeve 53 also drives the adapter pin 52 and above the cylinder core 48 in the locking direction 202 at. These also return to their respective starting position. Now all parts are back in their original position.

If the key is then reintroduced and accidentally turned against the blocking direction 202, the cylinder core 48, the adapter pin 52 and the driving sleeve 53 are rotated counter to the locking direction 202, but the locking sleeve 54 and the coupling sleeve 55 are not moved again due to the freewheel. The driver sleeve 53 pivots only relative to the detent sleeve 54 until the second actuating surfaces 80b of the driver sleeve 53 abut the second rib edges 96b of the drive ribs 94 of the detent sleeve 54.

Due to the freewheel, the locking mechanism 5 thus has a pulse circuit. Pulse circuit means that the key for locking and unlocking the cylinder lock 13 is rotated, after the release, however, in each case automatically, in particular by spring force returns to its initial position, the blocking or unlocking of the actuating mechanism 4 is retained. That is, the health status or the health status, that is, whether the operation mechanism 4 is inoperative or functional, does not change.

Advantage of the pull handle according to the invention is that the coupling pin, which is used for coupling with outside of the pull handle housing coupling elements for unlocking the lock performs a linear movement and is freely rotatable about the actuating axis. As a result, the connection to the other coupling elements is much easier and the wear at the coupling point is significantly lower. In addition, the movement of the coupling pin takes up less space. Of course, it is within the scope of the invention that an element with a different shape is used as the coupling element instead of the coupling pin.

Due to the fact that the axle bolt is arranged completely within the grip part, in particular the bearing area of the grip part, the axle bolt and its bearing are protected. This ensures a permanently smooth operation of the handle part.

According to a further embodiment of the invention ( Fig. 35-37 ), the pulling handle 1 instead of the coupling sleeve 55 on a locking sleeve 210. This is used to lock or unlock the pull handle. 1

The locking sleeve 210 ( Fig. 35-37 ) is preferably made of plastic and has a locking sleeve longitudinal axis 211 which is coaxial with the cylinder axis 51. Furthermore, the locking sleeve 210 has a first locking sleeve end 210a and an opposite, second locking sleeve end 210b. The pot-shaped locking sleeve 210 also has a barrier sleeve wall 212 with a wall inner surface 212a and a Wandungsaußenfläche 212b. The locking sleeve wall 212, viewed from the first locking sleeve end 210a in the direction of the locking sleeve longitudinal axis 211, initially has a circular-cylindrical bearing section 213. The bearing portion 213 is formed analogously to the bearing portion 103 of the coupling sleeve 55. The circular-cylindrical bearing section 213 is adjoined by a transition section 214, which corresponds to the transition section of the coupling sleeve 104. In the region of the transition section 214, the locking sleeve wall 212 tapers toward the locking sleeve longitudinal axis 211. That is, the outer diameter and the inner diameter of the lock sleeve wall 212 decrease. At the transition portion 214 of the locking sleeve 210, however, no guide portion 105, but a locking sleeve bottom 215 connects, which is preferably plate-shaped and extending perpendicular to the locking sleeve wall 211. The locking sleeve bottom 215 has a continuous bottom recess 216.

The locking sleeve 210 is thus formed, except for the locking sleeve bottom 215, substantially analogous to the coupling sleeve 55. Instead of the coupling pin 106, however, the locking sleeve 210 has two preferably radially with respect to the locking sleeve longitudinal axis 211 locking bars 217. The locking strips 217 close to the outer wall surface 212b of the locking sleeve wall 212 and stand from this in the radial direction. In addition, the two locking strips 217 extend in the circumferential direction of the locking sleeve wall 212. The locking bars 217 each have a the second locking sleeve end 210b facing locking surface 218, which is preferably planar and perpendicular to the locking sleeve longitudinal axis 211. The locking strips 217 also each have a first locking sleeve end 210a facing locking bar contact surface 220, which is preferably planar and perpendicular to the locking sleeve longitudinal axis 211. In addition, the blocking strips 217 are arranged in the region of the bearing section 213 at a distance from the first locking sleeve end 210a. Between the two locking bars 217 two passage spaces 221 are present.

Guide slots for guiding the locking sleeve 54 and a window for receiving the two spring pins 40, 82, the locking sleeve 210 but not on.

However, the locking sleeve 210 analogous to the coupling sleeve 55, a plurality of circumferentially arranged in the circumferential direction of the locking sleeve 210, ribs 219. The ribs 219 close to the wall inner surface 212 a of the barrier sleeve wall 212 and are in the radial direction from this. The ribs 219 begin in the bearing portion 213 and extend into the transition section 214. In addition, the ribs 219 have a first rib end 219a facing the first stop sleeve end 210a and a second rib end 219b facing the second stop sleeve end 210b. The first rib end 219a is spaced from the first barrier sleeve end 210a. The second rib end 219b is slightly spaced from the stopper sleeve bottom 215. A receiving trough for receiving the first compression spring 114 is preferably not present, since this is also not present in the second embodiment of the pull handle 1.

In the further embodiment of the pull handle 1, the cover 8 also has no guide bushing 131, but only the cover plate 130. This is where the guide bush 131 would be arranged closed. However, the cover plate 130 has a continuous access recess 222, which is arranged in the region of the threaded bore 146 of the connecting block 139. As a result, the threaded bore 146 is accessible from the outside and can be connected to the actuating mechanism of a lock. In addition, the cover plate 130 has two further passage recesses, which are penetrated by fastening screws, which in other Anschraubdome 223 with internal thread ( Fig. 36 and 37 ) of the bearing part 2 are screwed.

Furthermore, in the further embodiment of the pull handle 1, the coupling pin 56 and the clamping ring 205 are missing.

In the assembled state of the pull handle 1 according to the further embodiment, the cover plate 130 of the lid 8 closes off the bearing housing 7 at the open end thereof as well.

The locking sleeve 54 is arranged in the bearing portion 213 of the locking sleeve 210. The two locking arms 90 of the locking sleeve 54 are arranged between two ribs 219 of the locking sleeve 210. The sliding surfaces 91 of the latching arms 90 abut against the ribs 219. In this case, the latching sleeve 54 is arranged in the region of the first rib ends 219a of the ribs 219. The locking sleeve 210 is thus analogous to the coupling sleeve 55 with the locking sleeve 54 to the cylinder axis 51 non-rotatably connected. Respectively. the locking sleeve 210 is rotatably driven with the locking sleeve 54 about the cylinder axis 51 in connection. However, in contrast to the coupling sleeve 55, the locking sleeve 210 is not displaceable in the axial direction, ie parallel to the cylinder axis 51, relative to the locking sleeve 54.

The locking sleeve 210 is namely immovable but rotatably mounted about the cylinder axis 51 in the bearing part 2, in particular the bearing housing 7. For this purpose, the bearing portion 213 of the locking sleeve 210 is disposed in the bearing sleeve 42 of the bearing housing 7. In particular, the outer wall surface 212b of the barrier sleeve wall 212 lies in the region of the bearing section 213 on the bearing sleeve inner surface 44 at. In addition, the locking strip contact surfaces 220 bear against the bearing sleeve end 42b on the bearing sleeve 42. As a result, the locking sleeve 210, in contrast to the coupling sleeve 55 can not be moved further into the bearing sleeve 42 into it. The barrier sleeve bottom 215 is also arranged opposite to the cover plate 130 and is preferably on this. And the bottom recess 216 of the locking sleeve bottom 215 is penetrated by the foot 52b of the adapter pin 52.

The two fork arms 140 of the driving fork 57 are arranged inside the bearing housing 7 and on the outside around the locking sleeve 210, in particular the bearing area 213, surround the locking sleeve 210. The locking sleeve 210 is thus arranged in the receiving area 141. However, the actuating projections 143 of the fork arms 140 are not at the locking surfaces 218 of the locking bars 217 of the locking sleeve 210 at. On the contrary, the locking sleeve 210 is twisted in such a way in relation to the driving fork 57 that the passage spaces 221 are arranged in the region of the actuating ends 142 of the fork arms 140 ( Fig. 37 ). As a result, the fork arms 140 can slide past the barrier sleeve 210 through the passage spaces 221. This is the unlocked state of the pull handle 1 and der Sperrhülse 210.

If the pull handle 1 is attached to an element of the vehicle door or flap, the cover plate 130 is secured to the element in a manner known per se by means of the fastening screws, which are screwed into the Anschraubdome 223. This type of attachment is particularly well suited for applications that have narrow space conditions on the inside of the door.

• Um die Schlossmechanik des jeweiligen Schlosses auszulösen, wird von einer Bedienperson am Griffteil 3 gezogen. Dadurch wird auch die Mitnehmergabel 57 und folglich die Gewindebohrung 146 in Griffbetätigungsrichtung 208 verschwenkt. Die Sperrhülse 210 wird nicht verschoben. Die Betätigungsenden 142 der Gabelarme 140 werden durch die Durchgangszwischenräume 221 durchgeführt und außen an der Sperrhülse 210 vorbei geführt. Das mit der Gewindebohrung 146 verbundene Element des Betätigungsmechanismus des Schlosses wird somit ebenfalls in Griffbetätigungsrichtung 208 verschwenkt. Dies führt dann zu einer Betätigung der jeweiligen Schlossmechanik.

The mode of operation of the pull handle 1 according to the invention will now be explained in more detail below according to the further embodiment:

• To trigger the lock mechanism of each lock is pulled by an operator on the handle part 3. As a result, the driving fork 57 and consequently the threaded bore 146 in the handle actuating direction 208 are also pivoted. The locking sleeve 210 is not moved. The operating ends 142 of the fork arms 140 are passed through the passage spaces 221 and guided outside the lock sleeve 210. The connected to the threaded bore 146 element of the actuating mechanism of the lock is thus also pivoted in the handle actuating direction 208. This then leads to an actuation of the respective lock mechanism.

Upon release of the handle part 3 pivots this, driven by the force of the leaf spring 179, opposite to the handle actuating direction 208 in its non-actuated position ( Fig. 35 ) back.

The above-described operation applies to unlocked or unlocked pull handle 1, that is, if the locking mechanism 5, in particular the cylinder lock 13, in its non-locking or unlocked position the actuating mechanism 4.

If the pull handle 1 is locked, this is done as described above. In this case, the locking sleeve 210 is driven in Zusasserrrichtung 202 of the locking sleeve 54. In this case, the locking strips 217 are rotated such that they are now arranged in the direction of the cylinder axis 51 in alignment with the actuating projections 143 of the fork arms 140 ( Fig. 36 ). As a result, the actuating projections 143 abut against the locking surfaces 218 of the locking bars 217.

The locking sleeve 210 is in its locking position. The driving fork 57 can no longer be pivoted in the handle actuating direction 208. This movement is prevented by the locking sleeve 210. This locks the driving fork 57 and on this the handle part 3. The lock mechanism can not be operated.

Otherwise, the operation of the pull handle 1 according to the second embodiment corresponds to the operation of the pull handle 1 according to the first embodiment. In particular, the pulse circuit with the freewheel is also present. The locking sleeve 54 and the locking sleeve 210 thus remain after releasing the key in its locking position. And upon re-insertion of the key and rotation in the locking direction 202, the locking sleeve 54 and the locking sleeve 210 are not moved again. And the unlocking is also analogous to the first embodiment, the locking sleeve 210 is pivoted by the locking sleeve 54 in its non-locking position in which it is decoupled from the driving fork 57.

The pull handle 1 according to the further embodiment is very simple and has a high reliability.
