Definitions
- the invention relates to a screen with a screen stick and a screen frame arranged on the screen stick, consisting of a screen spider formed by screen spokes, carrying a covering and of articulated with a slide on the screen stick slidably mounted slide and the screen spokes connected.
- Such umbrellas are known from practice, which have been widely used with such a structure, particularly as umbrellas, the purpose of which is to use them in bad weather when it is raining, but rain is often accompanied by wind or even storm.
- the covering provides the wind with a large area of attack with a correspondingly high load on the umbrella frame, which is structurally taken into account by the curvature of the umbrella spokes and the presence of the span spokes in the event that the wind hits the covering from the top, as is the case for the normal case applies when the screen is directed against the raindrops deflected by the wind.
- problems arise with gusty and rotating winds when the wind moves from the underside into the umbrella and attacks the umbrella frame from below.
- the invention is therefore based on the object of designing an umbrella of the type mentioned in such a way that even under the action of strong winds, the risk of the umbrella frame folding over with the covering is excluded or significantly reduced.
- a supporting spoke is articulated to at least one of the spokes, which has an articulated thrust part at its other end, which is longitudinally displaceably mounted on the screen spoke 'on its free end facing section.
- the length of the screen spoke between its free end and the articulated connection of the clamping spoke is at least the accumulated length of the supporting spoke and the length of the
- the umbrella spokes are formed from plastic struts and the tension of the covering in the open state is matched to the bending elasticity of the plastic struts and the support spokes such that only a sectoral folding of the umbrella frame with the covering is possible and a complete folding down the screen cap is prevented in the circumferential direction.
- Umbrella spokes as plastic struts offer the clear advantage over profiled metal struts that even if the umbrella spokes are deformed due to extreme gusts, there is no irreversible deformation of the umbrella spokes, but that the umbrella is usable again after folding back.
- the plastic struts have a diameter of 2-6 mm, preferably 3-4 mm, since in particular the smaller diameter interval provides sufficient strength without unnecessarily increasing the weight of the screen. It is further preferred if the support spokes are also formed from plastic struts so that they can hold onto the lightweight construction with sufficient strength. Furthermore, irreversible deformation is also prevented.
- the resistance of the umbrella to wind forces is also increased in that the umbrella frame formed from the umbrella spider with the covering forms a resilient element as an attenuator in the open state, which counteracts folding.
- the utility is further increased significantly if the spring strength of the attenuator is dimensioned so that only a sectoral folding takes place and thereby an automatic resetting is forced when the wind pressure decreases by the tensioned attenuator.
- the user does not have to intervene actively to fold the screen back into the basic state, which is often only possible with difficulty with the screens known from the prior art, since in the completely folded state the screen is again a stable but undesirable state adopts, which usually requires the screen to be closed, in which the user often gets his fingers caught due to the increased or changed tension of the screen cap.
- the sliding part is formed by a sleeve comprising the screen spoke with a sleeve nose in which the hinge axis for the articulated connection is arranged.
- the shield spoke assigned to the supporting spoke is designed at least over its length serving to shift the supporting spoke as a U-profile in which the thrust part designed as a sliding shoe is guided. Then if the diameter of the support spoke is less than the opening width of the U-profile, that is still
- the umbrella spoke assigned to the supporting spoke has a stop to limit the displacement path in the direction facing the umbrella stick, there is a further increase in the load capacity of the umbrella frame against winds hitting from below, since the umbrella spoke does not simply continue to open towards the pushing part in the open state can be moved.
- stop on the screen spoke is arranged at a distance from its free end, which due to the support spoke bends the screen spoke in the sense of pretensioning the open umbrella frame in the folding opposite direction, because this increases the force and thus the required wind force, which is necessary to fold down the umbrella frame.
- Fig. 1 is a perspective view of the inventive screen in the open state
- Fig. 2 shows the screen of Figure 1 in the closed state.
- the screen 1 shown in FIG. 1 is formed by a screen stick 2 and a screen frame 3 arranged on the screen stick 2, which is formed from a screen spider and tension spokes 6 formed by screen spokes 4 and having a covering 5 and articulated with one on the screen stick 2 slidably mounted slide 7 and the
- Spokes 4 are connected. On at least one, on the embodiment shown in the drawing on every second, clamping spoke 6, a supporting spoke 8 is connected in an articulated manner, which has at its other end an articulated connecting part 9, which is mounted in a longitudinally displaceable manner on the screen spoke 4, on its side free end facing section.
- the length of the screen spoke 4 between its free end and the articulated connection with the clamping spoke 6 corresponds at least to the accumulated length of the
- the umbrella spokes 4 and the support spokes 8 are formed from plastic struts, the tension of the covering in the open state being matched to the bending elasticity of the umbrella spokes 4 and the supporting spokes 8 such that only a sectoral folding of the umbrella frame 3 with the covering 5 is possible and complete Folding down the screen cap in the circumferential direction is prevented.
- the plastic struts have a diameter of 2-6 mm, preferably 3-4 mm.
- the umbrella frame 3 formed from the screen spider with the covering 5 forms a resilient element as an attenuator in the open state, which counteracts folding, the spring strength of the attenuator being dimensioned such that only a sectoral folding occurs and thereby an automatic reset when the wind pressure drops is forced by the tensioned attenuator.
- the thrust part 9 is formed by a sleeve comprising the shield spoke 4 with a sleeve nose, in which the hinge axis for the articulated connection is arranged.
- the screen spoke 4 assigned to the support spoke 8 is designed, at least on its length serving to shift the support spoke 8, as a U-profile in which the thrust part 9 designed as a sliding shoe is guided , wherein the diameter of the support spoke 8 is less than the opening width of the U-profile.
- the screen spoke 4 assigned to the support spoke 8 has a stop for limiting the displacement path of the thrust part 9 in the direction pointing towards the umbrella stick 2.
- the stop on the screen spoke 4 is arranged at a distance from its free end, which is a curvature of the screen spoke 4 in the sense of a bias of the open umbrella frame 3 in the opposite direction to the folding by the support spoke 8 causes so as to further increase the load capacity of the umbrella frame 3 and introduce a resilient element as an attenuator.
