AT502471B1 - Umbrella for use as shade provider, has opening rods fastened to upper end of standpipe or to tension rod, where standpipe is bent and tension rod is provided with different lengths for providing asymmetric umbrella surface - Google Patents

Abstract

The umbrella has a slider crown, a curved tension rod (5), and an asymmetrical covering that are combined in a slider and are slid back and forth as a unit at a standpipe. Opening rods (6) are fastened to an upper end of the standpipe in a fixed crown or to the tension rod. The standpipe is bent and the tension rod is provided with different lengths. The opening rods are fastened to the tension rod in an adjustable manner.

Description

2 AT 502 471 B1

A screen is described, preferably for use as a shade dispenser. However, the invention is in principle applicable to all types of screens and is not limited solely to the type shown. In most of the umbrellas used so far, the bell that opens from the bottom and closes at the bottom is the state of the art with many variations.

A major drawback is the fact that when opening or closing the edge of the screen with the ends of the tension struts is always below the upper body level of the operator. The operator must therefore go outside the swinging radius of the screen edge when opening and closing. Only after a certain opening or closing angle can the operation be carried out inside or outside the umbrella bell at the end of the opening or closing process.

In addition, in this process by the heavier when opening umbrella bell 15 (on the lever of the opener struts on clamping struts), the already exhausting tension of Bespanzstoffes, added an additional effort.

The opening or closing screen requires a large radius of movement with its outer edges and can therefore be a disturbing factor for serving and passive people and objects.

The present invention therefore has the object to avoid the known disadvantages of the prior art. In order to avoid the disadvantages of the prior art, the object is achieved by the slider crown 3, the differently long curved tension struts 5 and the asymmetric fabric 7 are summarized in the slider 2 and slide as a unit on the curved standpipe 1 and down. On the other hand, the curved or open-ended curved struts struts 6 are fastened on the one hand to the upper end of the standpipe in the fixed crown 4 and on the other hand to the tension struts 5.

The particular advantage of the screen according to the invention is that the standpipe 1 35 is bent and the clamping struts 5 have different lengths to obtain an asymmetric screen shape. Due to the curved bar causes the greatest possible shade (in the mostly obliquely incident sunbeams) on the square next to the installation of the screen falls. Due to the asymmetrical arrangement of the screen area, the lower part of the screen does not become obstructed when sitting or walking under the screen. In addition, the screen edge with the clamping strut ends is always above the serving person, whereby persons or property damage are excluded by the tips of the clamping struts or the covering even during opening or closing of the screen. 45 The operator remains in the most comfortable position possible during the entire clamping or closing process directly at the curved standpipe.

In addition, in this inventive screen, the clamping process is facilitated by the clamping struts are opened centrally and directly over the slide crown and so the increasing weight of the clamping struts and the clothing from the joint outward by the supporting leverage of Öffnerstreben the force of clamping comes to help.

The opening or closing screen according to the invention does not require any oscillating movement radius with its outer channels and is not a disturbing factor for the person operating and other persons standing or sitting around, as well as objects.

Furthermore, it makes sense to provide the Öffnerstreben 6 with an additional covering 8, which causes a further absorption of heat radiation through the air gap. From 5 above, the view of the outside rod is hidden. This additional, possibly different-colored fabric together with the main fabric is another usable advertising space.

The covering 7 should not reach all the way to the slider crown, but instead of this, an opening can possibly drain off rainwater if the screen is closed.

However, in order to enable a complete closing of the screen, it is necessary to manufacture the tension struts 5 and the Öffnerstreben 6 with the same radius of curvature as the standpipe 1. 15

The invention is explained below with reference to the figures.

In the drawings, the screen according to the invention is shown, for example, with a symbolic operator. 20

FIGS. 1 to 3 show the different positions in the clamping process:

It goes without saying that the previously used buckling devices are just as applicable. 25

According to the illustrated embodiment, it is clarified that the screen edge with the clamping strut ends is always above the serving person, whereby persons or property damage are excluded by the tips of the clamping struts 5 or the asymmetrical covering 7 even during the opening or closing of the screen. 30

The operator remains during the entire Aufspann- or closing process in a comfortable position as possible directly at the curved standpipe. 1

Due to the asymmetric design of the different long clamping struts 5 with the Bespan-35 tion 7 Fig. 3 and the curved standpipe 1 which causes a superscript screen surface with less space is ensured by the oblique position a large shadow area.

The figure 1 shows according to claim 3 that the clamping struts 5 and the Öffnerstreben 6 have the same-40 chen radius of curvature as the curved standpipe to allow a complete closing of the screen.

Figures 1-3 show according to claim 4, that the double covering 8 on the Öffnerstreben 6 has a useful supplement for improved thermal insulation compared to simply covered-45 th models. In addition, the view of the often unattractive opener and tension bars 6 + 5 is concealed.

The fact that this second covering creates a further advertising surface or design effect is another additional advantage. 50

The device in Fig. 4 shows that the Öffnerstreben 6 are slidably mounted on the clamping struts 5 to compensate for the difference in length, which results from the bent standpipe. 55 Fig. 5 shows that with little space and large umbrellas are possible (e.g.

Claims (4)

Fig. 6 Should it rain there is a controlled water drain on the lower side. A lower wind attack surface from below through a bell open at the top (no parachute effect) makes the glider fly up much less easily and spin around the area. Fig. 7 claims: 1. Shade, preferably for shade, with standpipe (1), slide (2), slide crown (3), crown (4), curved clamping struts (5), curved opening struts (6) and asymmetric covering (7 ), wherein the slide crown (3), the clamping struts (5) and covering (7) in the slide (2) are combined and as a unit on the standpipe (1) slide up and down, the on or swinging opener struts (6) on the one hand on upper 20 end of the standpipe in the fixed crown (4) and on the other hand to the Spannstre ben (5) are fixed, characterized in that the standpipe bent and the clamping struts (5) have different lengths, thereby resulting in an asymmetric screen surface. 2. Apparatus according to claim 1, characterized in that the opener struts (6) are ver slidably attached to the clamping struts (5). 3. Apparatus according to claim 1, characterized in that the differently long clamping struts (5) and the Öffnerstreben (6) in the same curvature as the 'standpipe 30 (1) are made to allow a complete closure of the screen. 4.
