Definitions

• the present invention relates to an arm bearing for an articulated arm awning, with a bearing block which is attached to a support bracket so as to be pivotable about a tilting axis and which has at least one bearing eye at one end for rotatably receiving an awning arm, furthermore with a threaded rod for limiting a maximum tilting angle between the Support bracket and the bearing block, wherein a first end of the threaded rod is adjustably screwed into a receptacle of the supporting block and wherein a second end of the threaded rod has a head, which rests on a stop of the bearing block at the maximum tilt angle, finally with a locking element with which the head of the threaded rod can be fixed on the stop at the maximum tilt angle.
• the locking element In the known arm bearing, which is also referred to as a tilt joint due to the pivotable connection between the bearing block and the support bracket, the locking element consists of an angle piece, one leg of which is attached to the rotatable end of the awning arm, while the other leg projects freely.
• the arrangement is dimensioned such that rotation of the awning arm has the result that the second leg of the angle piece is rotated over the head of the threaded rod and thus fixes it to the stop of the bearing block.
• a high-impact protection is implemented, which prevents the tilted bearing block from accidentally striking back into a position that is no longer tilted. This can otherwise happen when the awning is extended, for example when a gust of wind falls under the awning cover from below.
• the well-known arm bearing is relatively simple. However, it does not offer the possibility of decoupling the fixing of the threaded rod from the angular position of the awning arm if necessary. For this reason, the known arm bearing is not readily usable as a rigid arm bearing with an adjustable angle of inclination.
• An arm bearing for an articulated arm awning is also known from EP 0 397 906 A1, in which the bearing block and the support block are arranged such that they can be pivoted relative to one another about a tilt axis.
• a locking element which in this case is designed as a translationally movable locking slide, in turn acts as a high-impact protection. This is the underlying problem regardless of a possible stop and can be easily manufactured.
• an alternative use of this articulated arm bearing in the form of a rigid arm bearing with an adjustable inclination angle is also not provided in this case.
• the locking element contains a translationally movable locking slide which can be coupled to the awning arm via a connecting element, the connecting element converting a rotary movement of the awning arm into a translational movement of the locking slide.
• a connecting element is provided in the present case, the removal or removal of which has the consequence that the locking slide is decoupled from the movement of the awning arm.
• the arm bearing according to the invention can therefore be converted from a tilting arm bearing to a rigid arm bearing and vice versa solely by the optional use of the connecting element.
• the optional use of the connecting element can be implemented in a technically and structurally very simple manner.
• the arm bearing according to the invention can accordingly be used in a simple manner either as an articulated arm bearing or as a rigid arm bearing.
• the arm bearing according to the invention has, in particular in its preferred configurations according to the subordinate claims, a number of further advantages.
• the production costs for the arm bearing according to the invention can be kept low, since the combined use now possibility of increasing the number of pieces considerably.
• the measure according to the invention due to the measure according to the invention, it is simple and inexpensive to convert such an arm bearing to the alternative possible use even after several years in operation.
• the preferred embodiment of the arm bearing according to the invention is very small, and it is particularly simple and robust.
• Figure 1 shows an arm bearing according to the invention in its use as a tilt joint arm bearing in a perspective view.
• FIG. 2 shows the arm bearing from FIG. 1, with part of the bearing block removed in order to obtain an insight into the functioning of the locking element;
• FIG. 3 shows the arm bearing according to FIG. 1 in a tilted position
• FIG. 4 shows the arm bearing from FIG. 3, again with part of the bearing block removed;
• 5 shows the arm bearing from FIG. 1 in its use as a rigid arm bearing with an adjustable angle of inclination;
• FIG. 6 shows the arm bearing from FIG. 5, again with part of the bearing block removed
• FIG. 7 shows the arm bearing according to FIG. 5, but with a fixed angle of inclination of 0 °;
• Fig. 9 shows a preferred embodiment to set the maximum tilt angle or the desired rigid tilt angle of the arm bearing according to the invention.
• an arm bearing according to the invention is designated in its entirety by reference number 10.
• the arm bearing 10 has a support bracket 12 on which a bearing bracket 14 is arranged to be pivotable about a tilt axis 16 in the direction of the arrow 18.
• the support bracket 12 and the bearing bracket 14 have mutually aligned bores through which a bolt 20 extending in the direction of the tilt axis 16 is inserted.
• the bearing block 14 has at one end a bearing eye 22 on which an articulated shaft 24 of an awning arm, not shown here, is rotatably mounted.
• the awning arm consists, in a manner known per se, of an aluminum hollow profile which is pushed onto the joint shaft 24.
• the joint shaft 24 will hereby so firmly connected to the awning arm that the terms "articulated shaft” and “awning arm” are used synonymously for the sake of simplicity.
• the awning arm 24 is rotatably mounted in the bearing eye 22 about an axis of rotation 26 in the direction of the arrow 28. This rotation is carried out when the awning is extended.
• the reference numeral 30 denotes a threaded rod, which in the present case runs transversely to the tilt axis 16 from the bearing block 14 to the support block 12.
• the first end 32 of the threaded rod 30 is screwed into a transverse bore, not recognizable in this illustration, of a bolt 34 with a corresponding internal thread.
• the bolt 34 thus forms a receptacle for the threaded rod 30.
• the threaded rod 30 is fixed in its current position by a spring element, not shown here, which presses a pin laterally into the thread of the threaded rod 30. It is an anti-rotation device. Alternatively, however, this can also be implemented in a manner known per se with a grub screw.
• the bolt 34 is seated in mutually aligned bores 36 which are arranged parallel to the tilt axis 16, but above it in mutually parallel legs 38, 40 of the support bracket 12.
• the threaded rod 30 therefore runs with its first end 32 between the two legs 38, 40 of the two-part support bracket 12.
• the threaded rod 30 has a head 42, in the end face of which an internal hexagon opening 44 is arranged.
• the internal hexagon opening 44 is able to receive an Allen key with which the threaded rod 30 can be screwed more or less deeply into the bolt 34.
• the bearing block 14 has an approximately oval through opening 46 through which the head 42 of the threaded rod 30 can pass.
• the housing element 48 in which the through opening 46 is arranged, has been removed in order to show the “inner life” of the bearing block 14. In fact, the housing element 48 cannot be removed from the arm bearing 10.
• the bearing block 14 has in its interior a stop 50 which, in conjunction with the head 42 of the threaded rod 30, limits the maximum tilt angle ⁇ of the bearing block 14 in the direction of arrow 18.
• the tilted state of the arm bearing 10 is shown in FIGS. 3 and 4, it being possible to see in FIG. 4 that the rear end 52 of the head 42 comes to rest against the stop 50 at the maximum tilt angle ⁇ .
• the reference number 60 in its entirety denotes a locking element which fixes the head 42 of the threaded rod 30 on the stop 50 in the tilted position of the arm bearing 10 shown in FIGS. 3 and 4. This prevents the rear end 52 of the head 42 from being released from its abutment on the stop 50, which is equivalent to the fact that the bearing block 14 counteracts the direction of the arrow 18 beats up.
• the blocking element 60 thus represents an anti-surge device.
• the locking element 60 has a locking slide 62 which is translationally movable parallel to the tilt axis 16 in a bore 63 of the bearing block 14.
• the locking slide 62 is a solid round bolt made of stainless steel in the present case. It is connected via a crossbar 64 to a push rod 66 which also extends parallel to the tilt axis 16 in the bearing block 14.
• the push rod 66 is biased by a spring 68 on a projection 70 within the bearing block 14.
• the free end 72 of the push rod 66 protrudes from the housing element 48 of the bearing block 14 and lies against an eccentric outer contour 74 of the joint shaft 24, which in the present case is cam-shaped.
• the locking slide 62 is connected in one piece to the push rod 66 via the crossbar 64.
• the locking slide 62 is detachably connected to the transverse web 64, so that the connecting element can be removed without replacing the locking slide 62.
• the locking element 60 is shown in its unlocked position, in which the head 42 of the threaded rod 30 can pass through the through opening 46 of the bearing block 14.
• the bearing block 14 is in this case folded up to the support block 12.
• the bearing block 14 is tilted in the direction of arrow 18, and the head 42 of the threaded rod 30 is secured by the locking element 60.
• the locking slide 62 is accordingly in a locking position, wherein it only laterally engages the hexagon opening 44 on the head 42 to such an extent that the threaded rod 30 can also be adjusted in the locked position.
• the unlocking and locking of the threaded rod 30 is brought about by the fact that the locking slide 62 is displaced translationally parallel to the tilt axis 16. This is done with the aid of the push rod 66, the translational position of which is determined by the position of the cam-shaped outer contour 74 of the joint shaft 24.
• the spring force of the spring 68 tends to move the gate valve 62 to its locked position. Accordingly, the spring 68 is relaxed in the locked position of the locking slide 62.
• the push rod 66 and the crossbar 64 together form a connecting element through which the locking slide 62 is operatively connected to the joint shaft 24 in such a way that an angular position of the joint shaft 24 around the axis of rotation 26 influences the translational position of the locking slide 62. If this operative connection is missing, the locking slide 62 remains in its assumed, translational position, regardless of the rotational angle position of the joint shaft 24.
• a second exemplary embodiment of the arm bearing according to the invention is designated in its entirety by the reference number 80.
• the arm bearing 80 differs from the previously described arm bearing 10 essentially in that the connecting element consisting of the crossbar 64 and the push rod 66 is missing. Accordingly, the bore 82 in which the push rod 66 was guided in the arm bearing 10 is empty.
• the arm bearing 80 is thus a rigid arm bearing, the tilting angle ⁇ of which can be adjusted with the aid of the threaded rod 30 by screwing the threaded rod 30 more or less into the bolt 34.
• the tilt angle ⁇ is independent of the rotational angle position of the joint shaft 24 due to the lack of a connecting element.
• FIG. 9 shows a particularly preferred possibility in order to adjust the tilt angle ⁇ of the arm bearings 10, 80.
• an adjusting device 88 in the form of a known standard gear 90 is used, which is connected to the threaded rod 30 via a coupling pin 92.
• the coupling pin 92 has an Allen head 94 which corresponds exactly to the internal hexagon opening 44 of the head 42.
• the standard gear 90 can be operated in a manner known per se on its ring-shaped control element 96 with a crank rod, not shown here. It transmits the rotary movement of the crank rod to the coupling pin 92 and thus to the threaded rod 30.
• a holding plate is attached to the end face of the pedestal 14, which carries a universal joint.
• One end of the universal joint has a hexagon pin which can be inserted into the inner hexagon opening 44 of the threaded rod 30, at the other end is an operating element, for. B. arranged as the control element 96, via which the universal joint can be driven.
