Definitions

• the invention relates to a Freiarmle according to the preamble of claim 1.
• a Freiarmwall of the type mentioned is known for example from EP 1 550 383 A.
• the Freiarmhold has a mast on which a retractable and extendable boom is arranged. At the free end of the boom, a transversely projecting approach is present, on which a screen is arranged by means of a canopy over a hinge.
• the screen has a slider which is pivotally connected by support struts with roof bars, which in turn are hinged to a connected to the umbrella pole crown.
• the umbrella pole has an upper insertion part with which it engages with the umbrella open in a receiving part of the approach and thereby blocks the joint.
• the disadvantage is that the crown of the screen by design with the screen open a relatively large distance from the boom, whereby the center of gravity of the open screen has a correspondingly large distance from the boom, which makes the tilting of the open screen by pivoting the boom about its axis and prevents a compact design.
• US Pat. No. 2003/0192580 A discloses another free-arm screen, in which a shoulder projecting transversely thereto is arranged at the free end of the arm.
• the approach has at the lower end a joint shell with an internal toothing, which cooperates with an attached at the upper end of the umbrella pole condyle with an external toothing.
• the crown of the umbrella is arranged in front of the condyle.
• the arrangement is not only very complex, but also causes a relatively large distance of the screen from the boom.
• the joint is always freely accessible and unprotected ..
• the opening of the screen by means of a rope by lifting the slider, wherein the teeth for fixing the position of the screen is brought into engagement.
• the disadvantage is that even a slight decrease the rope tension leads to a loosening or even loosening of the locking of the toothing, which can lead not only to damage to the teeth but in particular to an unwanted pivoting of the screen on the boom and thus to an accident hazard.
• the object of the invention is to improve the Freiarmlick of the type mentioned.
• the crown of the screen is arranged at the upper end portion of a sleeve formed as a sleeve part, which is displaceable over the approach that the crown exceeds the hinge with the umbrella open and at least approximately on the boom, resulting in a reduction of the center of gravity distance of the open Umbrella from the boom, which must be used for tilting the open screen by pivoting the boom less force.
• this training allows a reduction in the total necessary height of the free-arm.
• the fact that the crown exceeds the joint in the open state of the screen not only gives optimum protection of the joint, but the blocking of the screen in the set position is maintained even when the rope tension should subside.
• the crown may have an upper collar, in which a hinge pin is arranged, which is guided in a longitudinal slot of the neck, wherein the collar has on a side parallel to the hinge pin has a recess which corresponds approximately to half the cross section of the neck such that the crown is pivotable with the screen closed against the approach.
• the umbrella pole has at the upper part a pole part displaceable in the sleeve-like pole part, which is connected to the neck via the joint, wherein a groove delimiting the displacement path is present in the projection and in the connected pole part, in which engages a arranged inside the sleeve-like stock part or the crown sliding block.
• a recess on a collar is not required and the crown provides a closed image.
• the sleeve-like stock part is guided by the groove / sliding block arrangement on both sides of the joint against rotation.
• the approach can be unbössbar connected to the boom.
• the free-arm screen according to claim 4 is designed such that the attachment can be removed from the extension arm.
• FIG. 2 shows the free-arm screen of FIG. 1 in the closed state
• FIG. 3 shows the umbrella pole and suspension area of the free-arm umbrella of FIGS. 1 and 2 in the closed state, on a larger scale and in vertical section
• FIG. 4 shows the umbrella pole and suspension area of FIG. 3 in an opened position
• Figure 5 shows the suspension area of Figure 3 with a modified suspension
• FIG. 6 shows the suspension area of FIG. 5 with the umbrella open.
• the Freiarmwall has a mast 2, which may be anchored in the bottom 4 or in a base 6.
• a sliding bearing 8 At the upper end of the mast 2 is on a sliding bearing 8, a boom 10 in its longitudinal direction and retractable and mounted pivotably about its axis.
• the sliding bearing 8 is arranged pivotably on the mast 2 via a hinge 9.
• At one end of the boom carries a screen 12 and at the other end of the boom 10 is pivotally mounted in a bearing 14 about its axis.
• the bearing 14 is supported via a support element 16 on the mast 2.
• the support element 16 is fastened via a joint 18 to the bearing 14 and via a joint 20 to a support sleeve 22, which is arranged on the mast 2.
• a locking device 24 for locking the pivotal position of the boom 10 in a selectable pivot position available.
• the locking device is provided with a lying in the extension of the boom 10 handlebar 26 which is articulated against the support member 16 via a hinge 27.
• the steering rod can be latched to the support element 16 by means of a latching device 28.
• the handlebar 26 can be pivoted about the axis of the boom and by means of a coupling device, not shown in selectable angles of rotation relative to the boom with the interpretation ger releasably coupled to make the screen in the open state obliquely and lock in this position can.
• the screen 12 is arranged by means of an umbrella pole 30 via a joint 32 on a projection 34 which projects at the free end of the extension arm 10 and transversely thereto is arranged.
• the screen includes a slider 36 to which are secured by hinges 38 support struts 40, which in turn are connected by joints 42 on roof rods 44. The latter are in turn connected via joints 46 with a crown 48 which is fixed to the umbrella pole 30.
• the umbrella pole 30 is formed by a pole part 50, which is connected via the joint 32 with the projection 34.
• the umbrella pole 30 includes a sleeve-shaped stick portion 52 which is disposed above the stick portion 50 and at the upper end of the crown 48 is attached.
• the projection 34 is now formed so that it forms the continuation of the stick portion 50 and the crown 48 is movable by means of the sleeve-like pole portion 52 against the boom 10, so that the crown 48 with the screen 12 open exceeds the pivot point of the joint 32 and the boom 10 is pending.
• the umbrella pole 30 is provided with an anti-rotation lock 54, which consists of a groove 56 which extends in the projection 34 and in the floor part 50 to a stop 58.
• a sliding block 60 is arranged, which is movable in the groove 56, and whose displacement is limited by the stop 58 downwards.
• the projection 34 is detachably inserted in a recess 62 in a head portion 64 of the arm 10 and secured by a bolt 66 in the head portion 64.
• a pulling member 70 which is fixed to the slider 36 and extends through the umbrella floor 30 and the projection 34 in the head portion 64 of the arm 10.
• the tension member 70 is guided into the arm 10 and extends to the other end of the Ausle- gers, is further diverted into the handlebar 26 and finally reaches a winch 74, which is operable with a crank 76.
• the pulling member 70 is caught with the winch 74 until the slider 36 engages with a pin 78 in the sleeve-like stick portion 52.
• Figures 5 and 6 show a modified embodiment of the projection 34a of the joint 32a and the crown 48a.
• the projection 34a is in turn passable by the sleeve-like pole portion 52a.
• the crown 48a includes an upper collar 80 in which a hinge pin 82 of the hinge 32a is disposed.
• the hinge pin 82 is slidably mounted in a longitudinal slot 84 of the projection 34a. In the lowermost position, the hinge 32a is free and the crown 48a can pivot about the hinge pin 82.
• the collar 80 and the sleeve-like pole portion 52a parallel to the hinge pin 82 has a recess 86 which corresponds approximately to half the cross section of the projection 34, so that the screen can be pivoted in the closed state against the boom 10, as shown in FIG ,
• the projection 34a engages in the sleeve-like pole portion 52a and the hinge pin 82 is located at the upper end of the longitudinal slot 84.
• the sleeve-like pole portion 52a arranged above the projection 34a thus blocks the joint 32a.
• the longitudinal slot 84 provides a relatively long displacement of the sleeve-like pole portion 52a and thus the crown 48a, which carries the hinge pin 82, so that even here with a certain release of the tension of the tension member 70, the blocking of the joint 32a is maintained and so on unwanted oscillation of the screen is prevented against the mast.
