Patent Application
20140332043
This application claims priority from German application No. DE 20 2013 004 266.4 filed on May 7, 2013, the disclosure of which is incorporated herein by reference.
The invention relates to a large parasol with a binding system, particularly a large parasol with a textile fabric roof.
Large parasols have to be closed in adverse weather conditions, particularly with strong winds and approaching thunderstorms, in order to protect the parasol against damages, but also to preserve the persons and objects standing nearby from damage that arise, for example, from a parasol being moved by the wind.
From DE 20 2008 005 081 U1 there is known a corresponding securing system by means of which a large parasol in its closed state can be secured. The application of the securing system according to DE 20 2008 005 081 U1 may be appropriate for parasols up to a certain size. However, in the case of large rectangular parasols the closure level of the short struts can be so high that folding around of the parasol parts and correct attachment of a tying strap—as proposed in DE 20 2008 005 081 U1—is not possible without aids such as, for example, a ladder.
From patent application JP-2012/192073 A, there is known a binding system for a hand parasol that comprises a ring 21 and a securing device. The ring is slidingly moved on the closed parasol starting from the crown towards the ends of the struts 10 and, there, it holds together the fabric parts. For opening the parasol the ring is slid up to and beyond above the crown, whereupon the parasol struts can be spread open and the fabric sheets are released. The securing device serves to avoid that the ring may be lost. The securing device comprises one or several ribbons or cords which limit the range of motion of the ring, or it comprises limiting elements such as a roundel that is larger than the opening width of the ring. The ribbons are not intended for holding together the parasol fabric, and they are not wrapped around the parasol either in opposite directions or in a cross-like manner. Already in view of dimensions and weights JP-2012/192073 does not offer any solution or proposal for a large standing parasol.
Therefore, the object of the invention is to propose a binding system for a large parasol by means of which even short statured persons are able to bind the parasol conveniently and without climbing aids and also correctly, so that no wind damages in the sense described above, that is, damages of the parasol as well as of the persons and objects standing nearby, can arise.
The object of the invention is achieved by a large parasol with a binding system. Hereby, the measures of the invention have the result that the tying strap or the tying straps, in the opened state of the parasol, that is, in the standby position of the straps, are preferably in contact with a canopy strut and are fixed there at the upper and at the lower attachment point. In the dosed state of the parasol, when the securing system is activated, the tying strap or the tying straps are spirally wrapped around the parasol starting from the upper attachment point to the middle attachment point and are fixed there.
The binding system of the large parasol of the present invention comprises several ribbons by means of which the dosed parasol is wrapped in opposite directions, i.e. in a crossing over manner from the top to the bottom and, thereby holding together the fabric. The binding system of the present invention comprises stepped changeover attachment points B and C to which the tying straps 1 are fixed in the opened parasol (point B) or dosed parasol (point C). Furthermore, the invention does not require any movable tools (e.g. rings) that have to be slid along the parasol axis 2 between the upper end 3 and the tops of the parasol struts 10. Moreover, the invention does not require any securing device that would limit the range of motion.
In principle a single tying strap can be used. However, it is advantageous if the tying straps consist of two or even more sections. These sections can be e.g. distributed over two adjacent or over several canopy struts of the large parasol.
Usually it is appropriate if the tying straps are configured to cover a full 360° winding of the parasol, in which case the three attachment points are assigned to one section of a tying strap of the same canopy strut. If for specific applications it is appropriate to have more than or less than one whole winding of the parasol, then the middle attachment point can be attached to a further canopy strut.
An advantageous embodiment can be provided if the tying straps are guided in two layers on the respective canopy strut and the two strap parts can wrap the parasol symmetrically in opposite directions.
It will be advantageous if, at the upper attachment point, the tying straps comprise an eye or a loop that serves to fix, by means of a fixing screw, the tying strap to an attachment lug arranged at one of the canopy struts.
It is advantageous if at the middle and at the lower attachment points there are also provided attachment lugs being provided with one or several clamping rings by means of which the tying straps, which comprise hook-and-loop type fasteners at their lower ends, can be tensioned. Alternatively, buckles etc. can also be provided.
It can be particularly advantageous if the binding system is configured as a retrofittable set—particularly in case of a large parasol in which the cover fabric does not cover the long canopy struts but is attached at the sides of the long canopy struts by means of welt strips, thus meaning that the upper side of the canopy struts is free.
A further embodiment is obtained if the large parasol is configured in such is manner that the cover is tensioned over the canopy struts. In this case it is advantageous if tensioning rings are arranged at predefined, non-slidable attachment points above the cover fabric of the large parasol and are connected with the canopy struts through the cover fabric.
The aforementioned elements as well as those claimed and described in the following exemplary embodiments, to be used according to the invention, are not subject to any particular conditions by way of exclusion in terms of their size, shape, use of material and technical design, with the result that the selection criteria known in the respective field of application can be used without restrictions.
Further details; advantages and features of the object of the present invention will become apparent from the following description and the corresponding drawings, in which a securing system according to the present invention are illustrated by way of example. In the drawings there is shown in:
The large parasol 2 shown in
In the closed state of the parasol 2 the tying straps 1 are wrapped around the parasol 2 and the parasol cover 5, respectively, in a spiral-like manner. Thereby, they extend from the upper attachment point A, A′ to the middle attachment point C, C′. As a result of the distribution of the contact points along the spirally arranged tying straps 1 there arises only little pressure at each contact point, thus resulting in a reduced wearout risk for the parasol cover 8.
In the present exemplary embodiment, all of the three—or six, due to the doubled configuration—attachment points A, A′, B, B′, C and C′ comprise attachment lugs 10. At the upper attachment points A, A′ the tying strap 1 is firmly fixed by means of a loop or an eye 14 and a fixing screw 11. In contrast, the other two (or the other four, as the case may be) attachment points B, B′ and C, C′ a further comprise clamping rings 12 configured as clamping anchors to which—as shown in FIG. 5—the ends of the tying straps 1 can be attached to the damping rings 12 by means of a hook fastener (Velcro fastener) 15 by connecting the fleece part 15b to the hook part 15a.
