Storm strap arrangement for awnings with elastomeric polyurethane keder adapter and quick release.

Abstract

Storm strap arrangement for securing an awning against wind load, comprising a keder adapter that can be inserted into a keder rail of the awning, a quick-release device coupled to the keder adapter, a strap connected to the quick-release device, and a fastening device arranged at the bottom end, characterized in that the keder adapter is made of an elastomeric polyurethane material, is elastically deformable under tensile load and essentially returns to its original shape after unloading, and that the fastening device is designed as an elastic base plate made of polyurethane with at least one receptacle for a ground fastening element.

Description

Technical field The invention relates to a storm strap arrangement for securing awnings against wind loads, in particular vehicle awnings on motorhomes, caravans or similar camping vehicles. The storm strap arrangement serves to absorb tensile forces in a controlled manner, to establish a secure connection to the awning and to enable quick release when necessary. State of the art Storm securing devices for awnings are known from the prior art, employing webbing straps, quick-release units, keder rails or adapters, and elastic intermediate elements. In known designs, the elastic function is often achieved through separate spring components or textile or band-shaped elastic elements. A disadvantage of this approach is that the load is not specifically absorbed by a form-fitting connecting element, and the restoring characteristics can deteriorate under repeated loading. Furthermore, rapid release under wind load is not always provided by design in the immediate vicinity of the awning-side connection. The technical problem underlying the invention The invention is therefore based on the technical problem of providing a storm strap arrangement for awnings that enables reliable elastic load absorption, material-related return to the original shape, quick manual unlocking and robust ground-side fastening. Solution To solve this problem, a storm strap arrangement with the features of claim 1 is proposed. The arrangement comprises a keder adapter that can be inserted into a keder rail of the awning, a quick-release device coupled to the keder adapter, a webbing strap connected thereto, and a fastening device arranged at the bottom end. According to the invention, the keder adapter is designed as an elastomeric molded part made of polyurethane. The keder adapter is elastically deformable under tensile load and, due to its material properties, essentially returns to its original shape after unloading. The quick-release device is arranged directly on the keder adapter or in a connector area connected to it. The fastening device is designed as an elastic base plate made of polyurethane with at least one, preferably several, through-openings for receiving fastening elements. Advantages of the invention By designing the keder adapter as a polyurethane molded part, elasticity is integrated into a load-bearing connecting element. This allows tension peaks to be absorbed and cushioned directly on the awning side. The material-related elasticity of the keder adapter enables a defined return to its original shape after the load is released. The quick-release mechanism located directly on the keder adapter allows for rapid release even in the event of sudden high wind loads, enabling the awning to be retracted or relieved of load quickly. The elastic polyurethane base plate improves the connection to the ground and allows for secure fastening using, for example, countersunk screws, wood screws, or functionally equivalent fasteners. Example of implementation In a preferred embodiment, the keder adapter is designed for keder rails with a keder dimension of 5.0 mm. In another embodiment, the keder adapter is designed for keder rails with a keder dimension of 7.3 mm. The webbing is connected to the quick-release device and / or the base plate, preferably by sewing. Preferably, no separate metal spring is arranged between the keder adapter and the webbing, so that the elastic tensile strength is absorbed at least predominantly by the polyurethane keder adapter. The base plate preferably has several through-holes, allowing for different types of base mounting. Commercial applicability The invention is industrially applicable and particularly suitable for awnings on camping vehicles, recreational vehicles and comparable mobile or stationary shading devices.
