JP4713479B2 - Adjusting device for generating bilateral rotational movement - Google Patents

Description

  The present application relates to an adjusting device for producing a bilateral rotational movement according to the preamble of claim 1.

  From German Patent No. 199074832 (DE 199 07 48 132), an adjusting device is known which acts on two sides in order to produce a rotational movement, the device having a drive member and an output member inside. Having an attached housing, the output member being angularly adjusted by actuation of the drive member, and the adjustment device having a loop spring at least partially supported on the inner wall of the housing, the spring being subjected to torque on the drive side Then, the torque applied to the output side is blocked and contracted, thereby releasing the transmission of torque from the drive member to the output member. Both ends of the loop spring are connected to a transmission member mounted between the drive member and the output member, and this transmission member has a base body mounting circular segment shape around the axis of the output member. In order to reduce play when torque is transmitted from the drive member to the output member, the housing is tapered toward the shaft of the output member, while the transmission member or loop spring is in the direction of decreasing the housing diameter. The tension is applied in advance in the axial direction.

  In the case of a known adjusting device, the drive member can be provided with a compensation member guided in the radial direction or in the circumferential direction, the compensation member abutting against the stopper surface of the transmission member without play, and in the circumferential direction And two wedge-shaped levers that are displaceable in opposite directions, and a wedge slider that is spring-biased in the radial direction. The wedge slider is disposed between the lever-shaped levers and is disposed in the guide of the drive member. Here, the wedge slider has a central spring-loaded wedge guide guided by the guide of the drive member and is displaced by the radial displacement within the guide of the drive lever. The applied circumferential force is generated, thereby ensuring that there is not enough play.

  This type of adjusting device is suitable both for transmitting torque applied to the drive side from the drive member to the driven member and as a brake lock for preventing torque applied from the output side of the adjusting device. Use of a loop spring as a power transmission member to transmit the adjustment movement of the drive member to the driven member, or a loop spring that abuts a partially fixed adjustment housing by preventing the output side torque by expanding the loop In order to use a loop spring as a brake member for blocking by the cylindrical contact surface, on the one hand, ensuring maximum power transmission without any play from the drive member to the driven member and the torque applied to the output side. As soon as it is greater than or equal to the torque applied to the drive side, an exact harmony of the power transmission members is necessary in order to reliably prevent the torque.

  After the adjustment action has taken place and when the adjustment system is in a relaxed state, it ensures that the drive member is in the neutral position so as not to cause any unintentional adjustment of the adjustment mechanism of the vehicle connected to the adjustment device. There are additional problems in reverting.

Since many adjustment devices of this type are currently used, attempts have been made to reduce production costs while reducing production costs and equipment costs while reducing production costs.

  The object of the present invention is suitable for both drive and brake lock applications by using the same functional principle, allowing for easy mounting of the spring member and ensuring good power transmission between the drive member and the driven member. Or of the type described at the outset, ensuring a reliable prevention of torque applied to the output side and a reliable reset of the functional member of the adjusting device to the neutral initial position independent of the spring force of the spring member. The provision of adjustment devices.

  This is because, for a driver for power transmission from the drive member to the driven member, the coupling or brake lock has at least one loop spring band, the loop spring band having a circumference of less than 360 °. Further, this is achieved by having a contact surface for transmitting power from the drive member to the driven member, or from the driven member to the output member, or from the output member to the adjustment housing.

  The solution of the present invention allows a simple, more particularly floating, support of the loop spring band used as a spring member, and further by means of a reinforcing lever acting on the end of the spring, the drive member and the follower member. Therefore, reliable prevention of torque applied to the output side and reset of the functional member of the adjusting device to the neutral initial position are ensured regardless of the spring force of the spring member. It becomes.

  The coupling includes a reinforcing lever that is actively connected to the drive member, and a loop spring band that at least partially abuts against the hollow cylindrical abutment surface of the driven member in a pre-tensioned state, Preferably, the spring end is actively connected to the reinforcing lever.

  The reinforcing lever can be rotated with play around the adjusting shaft and has at least one cam arranged between the spring ends of the loop spring band, which cam rotates from the neutral intended position of the drive member. In order to transmit the driving torque generated by the driving member by the movement, the loop spring band is expanded, the loop spring band is brought into contact with the hollow cylindrical contact surface of the driving top in a frictional engagement state, and is reinforced. The lever is actively connected to the transmission lever, and the transmission lever acts on the support arm inclined with respect to the loop spring band when the driving member is reset from the displaced position to the neutral initial position. As a result, the loop spring band is pulled together, and the lock contact by the friction against the hollow cylindrical contact surface of the drive top is released.

  In the first and second embodiments, the coupling has two transmission levers attached to the drive shafts of the drive member and the driven member in addition to the loop spring band attached in a floating state. The levers have radial lever arms, each of which is opposed to a tilted support arm from the loop spring band, with one of the spring ends of the loop spring band at its inward end. And a second lever arm that abuts a stopper fixed to the housing and abuts a connecting bolt with a drive member of the reinforcing lever, so that the loop spring band and the drive member are connected to each other. Each of the resetting springs provided between the transmission arms for resetting is independent of one of the radial directions of the transmission lever, regardless of the reset direction. In order to press the bar arm against one of the tilted support arms of the loop spring band and reset the drive member regardless of the direction of reset motion, push the second lever arm against the connecting bolt connected to the drive member Hit it.

  In this way, a reliable reset of both the drive member and the loop spring band to the neutral initial position is ensured by a single spring, independent of the spring force of the loop spring band.

  The two transmission levers attached to the adjusting shaft extend radially from the adjusting shaft, cooperate with the inclined support portion of the loop spring band, abut against a stopper fixed to the housing, and are actively connected to the reinforcing lever. Preferably, a lever arm is provided. Furthermore, at least one resetting spring is provided between the transmission levers, which resets the transmission regardless of the direction of the reset action in order to reset the drive member connected to the loop spring band and the reinforcing lever.

  In the first embodiment, the resetting springs are attached to two lever protrusions, which extend from the radial lever arm of the transmission lever and are curved in the circumferential direction. The lever protrusions extend concentrically with the adjusting shaft from the radial lever arm of one transmission lever to the radial lever arm of the other transmission lever and are aligned with each other and beyond Furthermore, the resetting spring is supported by a radial lever of the transmission lever.

  In the second embodiment, the transmission lever has a second lever arm that abuts on a stopper fixed to the housing and abuts on a connecting bolt with a drive member of the reinforcing lever. In order to reset the driving member regardless of the direction of the reset movement, each of the second lever arms of the transmission lever is pressed against a connecting bolt connected for interlocking with the driving member.

  In this second embodiment, two resetting springs are guided by a curved protrusion of the transmission lever and supported by a second lever arm in the radial direction of the transmission arm. There is a slight play between the contact projection that contacts the tilted support arm of the loop spring band and the tilted support arm of the drive member at the neutral start position, and the contact projection is the roof spring band and the drive member. To reset the loop spring band, the engagement by the circumferential force optimum for resetting the loop spring band and the drive member is ensured.

  Furthermore, in this second embodiment, one spring end of the loop spring band and the end of the inclined support arm can be connected to each other by a web, and the inclined support arm of the loop spring band has a crack connecting part. Can do. In order to reduce the manufacturing cost, instead of this, the spring end of the loop spring band is made thick without providing cracks.

  In order to ensure radial mobility during power transmission from the actuating lever to the driven member or the driving top, the reinforcing lever is connected to the adjusting shaft through an elongated hole.

  In the embodiment in which the contact protrusion with the resetting spring is provided on the lever arm in the radial direction of the transmission lever, the stopper cam protrudes in the axial direction from the contact protrusion and contacts the stopper fixed to the housing. In this embodiment, the reinforcing lever is formed in two parts, and includes a cam formed in the first reinforcing lever part and provided between the spring ends of the loop spring band, and the reinforcing lever is an adjustment shaft. A first connecting member that is attached through a surrounding elongated hole and that is opposed in an oblique direction; and the first connecting member is connected to the second connecting member of the second reinforcing lever portion; The second reinforcing lever portion has a hole provided around the adjusting shaft and two stoppers that come into contact with the stopper cam of the transmission lever, and the two reinforcing lever portions are arranged above and below in the axial direction. Has been. Webs may protrude from the surface of the second reinforcing lever part on the side remote from the first reinforcing lever part, and these webs protrude through a circumferentially extending slot in the housing cover connected to the adjustment housing, and the lever The lever screw plate can be connected to an operating lever or an operating wheel.

  In the third embodiment, the reinforcing lever has two abutting surfaces arranged symmetrically with respect to the drive shaft, and these abutting surfaces are reinforced from the connecting portion with the spring end of the loop spring band of the reinforcing lever. Extending obliquely with respect to the axis of symmetry extending to the active connection with the drive member of the lever, the abutment surface facing the corresponding end surfaces of the two inclined support arms of the loop spring band, and The center end of the centering and resetting spring mounted coaxially with the drive shaft and the stopper partly fixed at the active connection between the reinforcing lever and the drive member, and the protrusion of the loop spring band Abut.

  The invention and further details of the invention will be explained in more detail with reference to the embodiments shown in the drawings for an adjusting device configured as an adjusting driver and a brake lock.

The cross section shown in FIG. 1 of the adjusting device of the first embodiment shows a member 11 that is rotationally driven around the adjusting shaft 10 , that is, an angular displacement member , which depends on its shape and thereafter a cylindrical support surface 110. Named "Drive Stopper" with The driving stopper 11 is driven by an operating lever 1 that can be swung around an adjusting shaft 10 as a driving member, depending on the turning direction of the operating lever 1 through an adjusting driver described below with reference to FIGS. It is rotated around the adjusting shaft 10 in one direction or the other direction.

  The loop spring band 31 provided with the floating support portion is inserted into the hollow cylindrical inner space of the drive stopper 11 and pre-tension is applied. Therefore, the loop spring band 31 extends from the hollow cylindrical inner space of the drive stopper 11. Jumps up when removed. The loop spring band 31 has several spring ends 310-313, of which the outer spring ends 310 and 311 are formed at the ends of the loop spring band 31, and the second spring end 312. , 313 are formed at end portions of the support arms 314 and 315 inclined of the loop spring band 31. Both spring ends 310 to 313 are connected to each other by webs 318 and 319.

  The cams 51 and 52 of the reinforcing lever 5 are located between the spring ends 310 to 313 of the loop spring band 31, and the reinforcing lever 5 is attached to the adjustment shaft 10 through the long hole 50. On the opposite side of the adjustment shaft 10 from the cams 51 and 52, a connecting bolt 53 for connecting the reinforcing lever 5 to the operating lever 1 is provided.

  The inclined support arms 314 and 315 of the loop spring band 31 have crack-like connecting portions 316 and 317, which are formed by, for example, breaking the loop spring band 31 and inserting a rotating shaft. As a result, the outer spring ends 310 and 311 of the loop spring band 31 are supported by an accurate and close press-fitting to the inclined support arms 314 and 315. With such a configuration of the spring end portions 310 and 311 of the loop spring band 31, the force acting on the loop spring band 31 by the cams 51 and 52 of the reinforcing lever 5 is received without any problem, and the flexibility of the loop spring band 31 is achieved. The accumulation of certain power is guaranteed.

  Two transmission levers 71 and 72 are attached to the adjusting shaft 10, and these are inclined by the contact protrusions 714 and 724 formed at the ends of the radial lever arms 710 and 720. The support arms 314 and 315 are opposed to each other with play, and come into contact with the support arms 314 and 315 inclined by the loop spring band only at the time of resetting. The transmission levers 71 and 72 are supported by a stopper 40 fixed to the housing by a connecting bolt 53 of the reinforcing lever 5 and a second lever 711.712 having a mounting relationship with the adjustment shaft 10 opposite to each other.

  The levers of the transmission levers 71, 72 each extend from one radial lever arm 710, 720 of the first transmission lever 71, 72 to the other second lever arm 711, 721 of the first transmission lever 71, 72. The protrusions 712, 713; 722, 723 are aligned with respect to each other and can move beyond each other, and reset springs 91, 92 are attached to them, and the reset springs 91, 92 have a radius. Both supported by the direction or second lever arm 710, 711, 720, 721, to position or return the actuating lever 1 to the center and to reset the loop spring band 31 to the neutral initial position Fulfill.

The function of the adjustment driver shown in FIG. 1 will be described below.
When the actuating lever 1 pivots around the adjusting shaft 10 in one direction or the other direction, the connecting bolt 53 similarly turns in the turning direction, and in this turning direction, the second lever arm 711 or 721 contacts the connecting bolt 53. The transmission lever 71 or 72 rotates in the same way, so that the two reset springs 91 and 92 are compressed. By connecting the operating lever 1 to the connecting bolt 53, the reinforcing lever 5 also rotates together, and after a short idle movement, abuts against the spring end portions 310 to 313 of the loop spring band 31. Carry in the direction of rotation around the adjustment shaft 10 corresponding to the turning direction. Illustratively, when the actuating lever 1 pivots clockwise about the adjustment axis, the cam 51 abuts against the spring end 311 and the cam 52 abuts against the spring end 312, while the actuating lever 1 moves around the adjustment axis. When turning counterclockwise, the cam 51 comes into contact with the spring end 310 and the cam 52 comes into contact with the spring end 313. Therefore, the cross contact of the cams 51 and 52 with the spring ends 310 to 313 occurs at each time point. Done in

  Thereby, the reset springs 91 and 92 are further tensioned until the end of the turning stroke of the operation lever 1, while the contact protrusions 714 and 724 in the first lever arms 710 and 720 of the transmission levers 71 and 72 are the reinforcing levers. When 5 is deviated from the neutral initial position, a certain distance is maintained from the inclined support arms 314 and 315 of the loop spring band 31.

When a force no longer acts on the operating lever 1 at the end of the adjustment stroke, the reset springs 91 and 92 for resetting the operating lever 1 push the transmission levers 71 and 72 toward the neutral initial position. When the second lever arms 711 and 721 of the transmission levers 71 and 72 are brought into contact with the connection bolt 53 , the operation lever 1 that is similarly attached to the connection bolt 53 also has the reinforcing lever 5 at the neutral initial position. Positioned and moved until the contact projections 714 and 724 of the lever arms 710 and 720 in the radial direction of the transmission levers 71 and 72 come into contact with the inclined support arms 314 and 315 of the loop spring band 31. In the neutral initial position where no tension is applied, the functional member of the adjusting device returns to the neutral initial position easily and smoothly, that is, in a substantially friction-free state.

Since both the cam 55 of the reinforcing lever 5 ′ and the protruding portion 334 of the loop spring band 33 are moved in the rotational direction of the operating lever 1, the centering and resetting spring 94 has two outer spring end portions 330 and 331. The one abutment of the two is expanded and tension is applied.

  When no force is applied to the operating lever 1 at the end of the adjusting stroke of the operating lever 1, the centering and resetting spring 94 pushes the reinforcing lever 5 'and the loop spring band 33 to return to the neutral initial position. Since the reinforcing lever 5 ′ does not apply any force to the outer spring ends 330, 331 and the inclined spring ends 332, 333 of the loop spring band 33, the loop spring band is the hollow cylindrical support surface 110 of the drive top 11. To the neutral start position without any significant friction, so that the reset takes place with almost no tension.

FIG. 6 shows a cross-sectional view of an adjusting device configured as a brake lock that prevents the torque applied to the output side as soon as it becomes greater than the torque applied to the drive side. In this embodiment as a brake lock, the loop spring bands 34 and 35 are similarly used as power transmission members that cooperate with the reinforcing levers 81 and 82.

  The two loop spring bands 34 and 35 are arranged so as to be shifted from each other in the adjustment housing 4, and are in contact with the cylindrical inner wall of the adjustment housing 4. The inclined support arms 341 and 351 of the loop spring bands 34 and 35 are in contact with the intermediate contact surfaces 810 and 820 of the two reinforcing levers 81 and 82, and these reinforcing levers are disposed in the adjusting housing 4 and the adjusting shaft 10. Arranged in secant-shape on each side. The outer spring ends 342 and 352 of the loop spring bands 34 and 35 are in contact with the outer contact surfaces 811 and 821 of the reinforcement levers 81 and 82, and these reinforcement levers are contact protrusions 812 facing the drive shaft 10. , 822 is supported by the output lever 20 of the output member 2.

The inclined support arms 341 and 351 of the loop spring bands 34 and 35 have sockets 343 and 353, and reset springs 95 shown as leaf springs are hung on these sockets. Tensions are applied toward each other in the direction of the arrow marked 6. As a result, the two outer spring ends 342 and 352 of the loop spring bands 34 and 35 are pressed against the outer contact surfaces 811 and 821 of the reinforcing levers 81 and 82, thereby the intermediate contact surfaces 810 thereof. , 820 are pressed against the inclined support arms 341, 351, and the contact protrusions 812, 822 of the reinforcing levers 81, 82 are pressed against the output lever 20. This ensures both play-free output and pressing contact of the loop spring bands 34, 35 against the hollow cylindrical inner surface of the adjustment housing 4.

  Drive members, in particular arcuate drive claws 12, 13 connected to the drive top 11 according to FIGS. 1 and 2 project into the adjustment housing 4, and their edges are inclined support arms of the loop spring bands 34, 35. 341, 351 and the stoppers 813, 823 of the reinforcing levers 81, 82.

Due to the action of the counter torque in the clockwise direction on the output side, the output lever 20 of the output member 2 is pressed against the abutting protrusion 812 of one reinforcing lever 81, whereby the reinforcing lever 81 rotates in the same clockwise direction. Be strong. Therefore, the outer and intermediate contact surfaces 810 and 811 of the reinforcing lever 81 are pressed against the inclined support arm 341 and the outer spring end 342 of one loop spring band 34. The force applied to the outer spring end 342 of the loop spring band 34 from the outer contact surface 811 of the reinforcing lever 81 is intended to rotate the loop spring band 34 in the clockwise direction. The force applied to the tilted support arm 341 of the band 34 cooperates with the frictional force generated by the abutment of the loop spring band 34 against the hollow cylindrical inner surface of the adjustment housing 4 to cause a self-locking action, whereby the brake The lock is fixed in this position, and counter torque applied to the output side is prevented without generating driving torque in the opposite direction.

When the drive top 11 according to FIG. 6 rotates counterclockwise, a brake lock is brought about against counterclockwise rotation of the drive claws 12, 13. Therefore, the edge of the driving claw 13 is pressed against the stopper 354 of the support arm 351 inclined of the loop spring band 35 in an unloaded state, and the edge of the driving claw 13 is the stopper of the reinforcing lever 81 by the driving claw 12. The stopper 354 is released slightly before it is pressed against the output lever 20 and pressed against the output lever 20 by the contact protrusion 812, so that the applied output torque can be directly compensated by the driving torque. According to the embodiment described below with reference to FIGS. 8 to 10 instead of via the lower part of the reinforcing lever 81, the power can also be transmitted directly to the output lever 20 via the extensions of the drive claws 12 and 13. it can.

  The brake lock is thus switched after the drive torque acts in the counterclockwise direction, and the drive-side torque transmitted through the drive claws 12 and 13 can be transmitted to the output member 2.

  When the drive member and therefore the drive claws 12 and 13 are switched in the direction of the counter torque on the output side, that is, in the clockwise direction, the loop spring band in which the end portion side of one drive claw 12 is tensioned as a result of the counter torque on the output side 34 is pressed against the stopper 344. The self-locking action of the loop spring band 34 is released and the output member 2 and thus the output pinion 21 can likewise be switched clockwise, where the output pinion 21 is on the one hand the output lever 20 and on the other hand for example a seat adjustment device. It is connected to an adjustment mechanism such as

  FIG. 7 shows a brake corresponding to the brake lock of FIG. 6 in which a compression spring 96 provided between the outer contact surfaces 811 and 812 of the reinforcing levers 871 and 82 is provided as a reset spring in place of the bent leaf spring. A cross section of the lock is shown. In this embodiment, the inclined support arms 341 and 351 of the loop spring bands 34 and 35 do not have a bent leaf spring, and therefore do not have a groove corresponding to the structure of FIG. A corresponding contact surface for the intermediate contact surface 810, 820 of the corresponding stopper or reinforcement lever 81, 82 is formed.

  The embodiment of the adjusting device shown in a plan view in FIG. 8 configured as a brake lock prevents more torque on the drive side from being applied to the output side, but more torque on the output side is output. It functions in the same way in transmitting to the side.

  For ease of understanding, the brake lock is shown in plan view in FIG. 8 in a fully assembled state, while FIGS. 9A-9F illustrate the relationship between the individual functional members of the brake lock. Each of the assembly stages of the brake lock is shown in FIG.

  FIG. 9A shows a hollow cylindrical adjustment housing 4, into which an output lever 20 of the output member 2 is inserted, and this output lever 20 has a reset spring guide 23 at one end and an output cam 22 at the other end. Further, grooves 24 and 25 are provided on both sides of the output cam 22, and a center hole 26 for receiving the adjusting shaft 10 of FIG. 9B is further provided.

  FIG. 9C shows the brake lock after inserting the first loop spring band 36 that contacts the cylindrical inner wall of the adjustment housing 4. The loop spring band 36 has an outer thick spring end 362 at one end and a contact plate 360 at the other end. A contact pin 361 protrudes from the contact plate 360 in the axial direction. In the circumferential direction of the plate 360, contact surfaces 363 corresponding to the contact surfaces of the inclined support arms 341 and 351 of the loop spring bands 34 and 35 of the embodiment of FIGS. 6 and 7 are formed.

  FIG. 9D shows the brake lock after the first reinforcing lever 84 is inserted. The outer contact surface 841 of the reinforcing lever 84 is in contact with the outer spring end 362 of the loop spring band 36. The intermediate contact surface 840 of the reinforcement lever 84 is in contact with the contact plate 360 of the loop spring band 36, while the other end of the reinforcement lever 84 forms a stopper protrusion 842 that engages with the groove 25 of the output member 2. ing.

  FIG. 9E shows the brake lock after the second reinforcing lever 83 has been inserted into the hollow cylindrical adjustment housing 4 of the brake lock. Similarly, the second reinforcing lever 83 has an outer contact surface 831 at one end and a stopper projection 832 that engages with the groove 24 of the output member 2 at the other end. An intermediate contact surface 830 formed as a cam projects vertically from the surface of the second reinforcing lever 83 and plays a role of applying tension when torque acts on the output side. According to FIG. 9F, the second loop spring band 37 is inserted into the hollow cylindrical adjustment housing 4, and therefore the outer spring end 372 contacts the outer contact surface 831 of the second reinforcing lever 83. .

  6 and FIG. 7, the contact plate 370 corresponding to the inclined spring end of the loop spring band, on the other hand, against the intermediate contact surface or the contact cam 830 protruding vertically from the reinforcing lever 83. The contact surface is formed, and on the other hand, the contact surface 373 of the driving top or the driven member with respect to the control member 111 shown in FIG. 8 and further the contact surface 371 with respect to the resetting spring 97 formed as an omega-shaped spring are formed. The other end of the reset spring 97 abuts against the abutment pin 361 of the first loop spring band 36, and thus applies a pre-tension in the circumferential direction to the loop spring band 36. The omega-like spring 97 is inserted into the adjustment housing 4 such that the legs projecting in the lateral direction abut against the resetting springs 23 projecting vertically from the surface of the output lever.

  FIG. 8 shows in plan view the fully assembled brake lock after inserting the drive top or driven member, and the control members 111-114 protruding from the drive top or driven member are shown in cross section in FIG. ing. The control members 111 to 114 are opposed to the contact surfaces 363 and 373 of the loop spring bands 36 and 37 on the one hand and the stopper cam 22 of the output member 2 on the other hand with play in the rotational direction angle. 6 and FIG. 7 is different from the brake lock of the embodiment shown in FIGS. 6 and 7 in that the control members 113 and 114 are not in contact with the stoppers 813 and 823 of the reinforcing levers 83 and 84 but directly to the drive cam 22 of the output member 2. It is in contact.

    When the counter torque in the clockwise direction with respect to the output side is applied, the output lever 20 of the output member 2 presses against the stopper protrusion 832 of the one reinforcing lever 83, so that the reinforcing lever 83 similarly strongly rotates in the clockwise direction. It is done. Therefore, the contact cam 830 and the outer contact surface 831 of the reinforcing lever 83 press against the contact plate 370 and the outer spring end 372 of the loop spring band 37. On the other hand, the loop spring band 37 is rotated clockwise by the force applied to the outer spring end 372 of the loop spring band 37 from the outer contact surface 831 of the reinforcing lever 83, and the loop spring band 37 is rotated by the contact cam 830. The self-locking action occurs due to the cooperation between the force applied to the contact plate 370 and the frictional force generated by the contact of the loop spring band 37 against the hollow cylindrical inner surface of the adjustment housing 4. The counter torque applied to the output side is prevented without affecting the driving torque.

  When the driving top 11 rotates counterclockwise, the control members 111 to 114 rotate counterclockwise in the brake lock. Therefore, the control member 112 presses against the stopper 363 of the contact plate 360 of the loop spring band 36 in the unloaded state, and the stopper 363 is moved slightly before the control member 113 presses against the cam 22 of the output lever 20. The output torque can be directly compensated by the drive torque. Therefore, the brake lock rotates after acting on the drive torque side in the counterclockwise direction, and can transmit the drive side torque to the output member 2.

  When the drive member and thus the control members 111 to 114 are switched in the counter torque direction on the output side, that is, in the clockwise direction, the control member 111 is pressed against the stopper 373 of the loop spring band 37 and the loop spring band 37 becomes the counter torque on the output side. Then tension is applied. As a result, the self-locking action of the loop spring band 37 is released, and the control member 114 can similarly rotate the output lever 20 and thus the output member 2 clockwise.

  In the brake lock shown in the schematic cross-sectional view of FIG. 10, a compression spring 98 is used instead of the omega-like spring as the resetting spring, and the compression spring 98 is in contact with the abutment protrusions 364 of the loop spring bands 36 and 37. It differs from the embodiment of FIGS. 8 and 9 only in that it is mounted between 374.

  FIG. 11 shows a cross-sectional view of an adjusting device likewise configured as a brake lock, which blocks the torque applied on the output side as soon as it becomes greater than the torque applied on the drive side, Accordingly, unlike the brake lock of FIGS. 6 to 10, a single loop spring band 38 is used as a power transmission member.

  Between the thick spring end portions 380 and 381 of the loop spring band 38, outer contact surfaces 851 and 861 provided at one ends of the two reinforcing levers 85 and 86 are positioned. These two reinforcing levers 85 and 86 are inserted into the loop spring band 38 symmetrically with respect to the axis of symmetry of the brake lock on both sides of the adjusting shaft 10, whereby the outer abutment surfaces 851 and 861 of the reinforcing levers 85 and 86. Are in contact with the thick spring end portions 380 and 381 of the loop spring band 38 without play.

  The ends of the reinforcing members 85 and 86 facing the output member 2 configured as an output cam are in contact with the output member 2 at their conical contact surfaces 855 and 865. A spring member 990 supported on the one hand by the adjusting shaft 10 and on the other hand by the support surfaces 856, 866 of the reinforcing levers 85, 86 ensures that there is no play in the brake lock, so that the reinforcing levers 85, 86 are looped. The outer end portions 380 and 381 of the spring band 38 are in contact with the stopper surfaces 384 and 385 of the inclined support arms 382 and 383, and the output member 2 is in contact with the conical contact surfaces 855 and 865.

  The arcuate drive claws 12 and 13 connected to the driven member, more specifically, the drive top 11 of the drive device of FIGS. 1 to 5 protrude into the adjustment housing 4, and the end edges thereof are reinforced levers 85 and 86. These stoppers 853 and 863 are positioned between the outer contact surfaces 854 and 864. Between the driving claws 12 and 13 and the inner surface of the loop spring band 38 are common springs 991 and 992, which are stoppers 121 and 131 of the driving claws 12 and 13, and stoppers 386 on both sides of the loop spring band 38. , 387 in the circumferential direction.

  When counter torque is applied in the clockwise direction of the brake lock on the output side, that is, in the direction of the arrow A attached to the drive cam 2, the drive torque from the drive claws 12 and 13 acts in the counter direction, and the drive claw 13 has a slight play. Then, the reinforcing lever 86 is pulled in the direction of the inclined spring end 383 of the loop spring band 38. The inclined surface of the output cam 2 aligned in a conical shape and the outer abutment surface 864 of the reinforcing lever 86 cause the reinforcing lever 86 to move along this inclination, thereby causing the loop spring band generated by the tension spring 990. The tension of 38 is released.

  After the driving claws 12 and 13 are moved at a slight rotation angle, the driving claws 12 come into contact with the outer abutment surface 854 of the reinforcing lever 85 and press against the outer cam 2 via the outer abutment surface 854, Thus, the outer cam 2 is moved in the direction opposite to the driving direction, that is, the direction of torque on the output side. For this reason, the accompanying springs 991 and 992 attached between the driving claws 12 and 13 and the loop spring band 38 apply a cooperating force to the loop spring band 38. During this time, the loop spring band 38 tends to move with them, and the friction between the loop spring band 38 and the adjustment housing 4 is easily overcome.

As another example for the co-operation of the loop spring band 38 during the movement of the drive pawls 12, 13, a single co-spring is provided between one of the two drive claws 12, 13 and the loop spring band 38. It is also possible.
