Definitions
- the invention relates to a limitation of failure for awnings according to the preamble of claim 1.
- Such an awning is known for example from DE-C1-4014962.
- the awning is provided with a braking device which is formed by at least one brake spring in the form of a helical spring which is arranged between the driven gear of the transmission and a piece which is fixedly connected to the transmission housing and which is held in a groove with an angled end, which is located in a hub firmly connected to this gearwheel, this gearwheel carrying the winding tube.
- This braking device prevents the awning fabric from unintentionally and unintentionally unwinding and at the same time vibrates the winding tube during certain working positions of the extension arms.
- a disadvantage of this known awning is that when the gear is turned further in the unwinding direction, in the case in which the desired unwinding position of the awning fabric has already been reached, further awning fabric material is unwound, so that the awning fabric is no longer taut, the wind that Can inflate and tear awning cloth like a balloon.
- the object of the invention is therefore to provide an awning of the type mentioned above, in which the further unwinding of awning fabric material is prevented after the awning fabric has reached the unwinding desired position.
- the invention is implemented in any case if there is a failure limitation that can be set with high accuracy, so that it intervenes practically at the same time as the desired position of the awning fabric is reached.
- the adjustment of the failure limit can be done in such a way that the awning material is first unwound, until the desired unwinder position is reached, in which the awning fabric is still under tension and the failure arms have reached their maximum extension position. Then the failure limit is set such that a further twisting of the winding tube is no longer possible, so that even when the crank rod is actuated further, the tension of the cloth is reduced.
- the failure limitation is preferably arranged at the opposite end of the winding tube with respect to the transmission and can be rotated and adjusted about the axis of the winding tube. As the rotation of the failure limitation is carried out continuously, the desired operating position of the failure limitation can be set with absolute accuracy. Come in addition, that the spatial separation of the failure limitation from the gearbox relieves the gearbox.
- the setting of the unwinding setpoint can expediently take place in that the pin part of the spindle has on its end face a means for rotation in the hole in the bearing plate and in that a plate leading to the hole is provided in this bearing plate, which narrows by means of a screw for clamping the pin part can be.
- a further embodiment of the invention provides that the spindle is provided with a collar having at least one stop and the barrel nut is provided with at least one stop which can be struck against the spindle stops.
- the locking device works together with a freewheel device, which acts between the gearbox and the winding tube in such a way that it reaches the freewheeling state after the unwinding setpoint position has been reached.
- a freewheel device acts between the gearbox and the winding tube in such a way that it reaches the freewheeling state after the unwinding setpoint position has been reached.
- FIG. 2 shows a side view of a bearing having the gear (right) for the winding tube and the counter bearing (left) for the winding tube with the unwinding locking device, the bearings being partially shown in section,
- FIG. 3 shows a rear view of a running nut which is connected non-rotatably to the winding tube
- Fig. 4 is a side view of the barrel nut in Fig. 3 and a partial section of this barrel nut along the line A-A in Fig. 3 and
- FIG. 5 is a plan view of the face of the barrel nut in FIG .. 3
- the awning shown in FIG. 1 has a support device to be fastened to a house wall or the like, which is provided with a winding tube 34 rotatably mounted in bearing plates 30, 30 '(FIGS. 1 and 2).
- the winding tube 34 can be moved by means of a gear 32, specifically via a crank rod 26 which can be hooked in or hooked out and which can be hooked into an actuating eyelet 28.
- Two extension arms are fastened to a support tube 24 arranged between the bearing plates 30, only one of which, the extension arm 16, is shown.
- the extension arm 16 consists of two legs 18, 20 which are connected to one another in an articulated manner by means of a joint 22, of which the leg 18 is connected to the support shaft connected part 36 is rotatably fastened by means of a joint 38 and the leg 20 to a downspout 10 exciting the awning fabric 14 by means of a joint 22 '.
- the downpipe 10 can also wear a valance 12.
- the joints 22, 22 ', 38 ensure that the extension arm 16 collapses in one plane.
- the legs 18, 20 are designed as tubes. In the interior of the tubular leg 20, a tension spring is arranged in a manner not shown, which is attached on the one hand to the joint 22 'and on the other hand to the joint 38 via a rope (not shown) running through the tubular leg 18.
- This tension spring is always so tensioned that it acts in the sense of unfolding the legs 18, 20.
- the actuating eyelet 28 is rotated by means of the crank rod 26, the downpipe 10 moves in the direction of the double arrow 13.
- the part 36 can be designed as an inclination adjustment device, when the downpipe 10 is actuated in the direction of the double arrow 15.
- the counter bearing, not visible in FIG. 1, for the winding tube 34 is shown on the right side of FIG. 2. It consists of a stiffened bearing pot 70 which is rotatably mounted with a central opening 71 on a pin part 76 of a spindle 72. On the circumference of the pot 70, axially parallel ribs 73 are evenly distributed, which engage in matching axially parallel grooves, not shown, on the inner circumference of the winding tube 34, so that the pot 70 is non-rotatably connected to the winding tube 34.
- the pin part 76 is non-rotatably fastened in a hole 72 in the bearing plate 30 '.
- the bearing plate 30 has a slot, not shown, which runs vertically above the pin part 76 and which can be narrowed by means of a screw 75, so that the pin part 76 can be clamped.
- the end of the pin part 76 has a recess 79, into which a key (not shown) for turning the pin part 76 and thus the spindle 72 can be inserted.
- the spindle 72 has a two-stop collar, only one stop 78 is shown, and a threaded part 77, on which an internally threaded barrel nut 80 runs.
- the running nut 80 has two on the side facing the stop 78 Stops 81, 82 and is mounted on its outer circumference in the pot 70 in a radially non-rotatable but axially movable manner.
- FIGS. 3 to 5 The structure of the running nut 80 is shown in more detail in FIGS. 3 to 5.
- this running nut has an outer jacket which is approximately octagonal in cross section with jacket sides 84 bent inwards between the corners, the centers of which are braced with a threaded ring 85 which carries the internal thread, so that eight chambers are formed, while the nut 80 remains stable.
- Said end face carries the two stops 81, 82.
- this stop has a surface in the form of a circular ring section which is delimited by an outer edge 86, an inner edge 87 and two radial side edges 88, 89 .
- the outer edge 86 forms a circular section with a larger radius, while the inner edge 87 represents a circular section with a smaller radius. From the side edge 88, the surface rises evenly to the side edge 89. The same applies to the stop 82.
- This running nut 80 is preferably made of plastic or metal.
- the pot 70 has an inner shape adapted to the jacket sides 84 and is accordingly provided with two to eight round inner longitudinal ribs on which the running nut 80 can slide axially.
- the stops 78 of the spindle 72 are designed to be dual to the stops 81, 82, so that the edges 89 can strike corresponding edges of the stops 78.
- the drive for the winding tube 34 is shown on the right side of FIG. 2. This drive can be used with advantage in the invention. However, other drives can also be used.
- the transmission consists of a housing 40 with two gear wheels 43, 44, which form a pair of bevel gears. The axes of rotation of the gears are arranged at right angles to one another, and teeth 42, 49 of the gears mesh with one another.
- the gear 44 is on one cylindrical shell-shaped portion 45 of the housing 40 rotatably mounted.
- a shaft 39 of the gear 43 is rotatably supported by its end 66 in the housing 40.
- a cylinder tube 46 is arranged in the interior of the section 45 and in a cylindrical recess of the housing 40 in the extension of the section 45 and is connected to the housing 40 in a non-rotatable manner.
- This cylinder tube 46 serves as a bearing for a hub-shaped part 37 of the gearwheel 44.
- An adapter 48 is in turn rotatably mounted on this part 37, which has the shape of a cylindrical drum open on one side, on which the winding tube 34 is fastened non-rotatably.
- Adapter 48 and part 37 of gear 44 are secured on cylinder tube 46 by means of a securing element 51 against horizontal displacement.
- the adapter 48 is a plastic injection-molded part and has a honeycomb-shaped and thus stable structure to save material.
- the mode of operation of the unwinding locking device according to the invention in connection with the drive having the freewheel device is as follows:
- the spring arranged in the leg 20 spreads the legs 18, 20 apart.
- the nose of the pawl 54 is in engagement with an edge of the recess 55 (further pawls and further recesses can also be provided).
- the running nut 80 is transported from the position shown in FIG. 2 on the spindle in the direction of the stops 78.
- the stops 78, 81 hit each other, so that a further unwinding movement of the winding tube 34 is prevented.
- the spring force of the tension spring in the leg 20 ensures that the awning fabric 14 remains taut. If the crank rod 26 should be turned further in the sense of unwinding, the pawl 54 comes out of engagement with the edge of the recess 55; this pawl leans with its inclined surface against another edge of the recess 55 and is pressed inwards into the chamber 53. This process can be repeated at other cutouts of the gear 44.
- the two gearwheels 43, 44 thus run in freewheel mode, while the winding tube 34 is locked by the running nut 80.
- the crank rod 26 is rotated in the opposite direction.
- the pawl 54 comes back into engagement with the first-mentioned edge of the recess 55 or a corresponding other edge, so that the winding tube 34 is carried along.
- the stops 78, 81 separate from one another again and the running nut 80 runs in the direction of the drive.
- An important advantage of the invention is that the user can choose the desired unwind position.
- the awning fabric 14 is unwound to the intended unwinding position.
- the screw 75 is loosened so far that the pin part 76 is rotatable in the hole 71.
- the key mentioned is inserted into the recess 79 and the spindle 72 is rotated until the running nut 80 strikes with its stop 81 against the stop 78 of the spindle 72.
- the screw 75 is tightened again.
- screw 75 can be designed as a wing screw and the pin part can be provided with a fixed crank.
- the barrel nut is made of plastic and can therefore be manufactured inexpensively because the freewheel device 53, 54, 55 possible further damage to the stops 81, 82 and when the crank rod 26 continues to rotate after reaching the unwinding desired position Internal thread of the nut 80 prevented.
- Another advantage of the invention is that the provision of stops 78 on the spindle 72 and stops 81, 82 on the running nut 80 prevents the running nut 80 from seizing up.
