ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a device for shielding a shed entrance, particularly during loading and/or unloading of a vehicle parked thereagainst, comprising:
a wall-mounted frame arranged on an outside wall round the shed entrance;
a hanging frame which is held in a plane substantially parallel to that of the wall-mounted frame and at a distance therefrom with resilient separating means; and
at least one fabric element extending at least over the distance between the wall-mounted frame and the hanging frame.
2. Description of the Related Art
Such devices are generally known in the art, wherein use is made of large numbers of different profiles and connecting means. As a consequence of this wide diversity of components, the cost price of such known device is high and placing of such a known device is laborious and time consuming. In addition, the wall-mounted frame and the hanging frame are usually manufactured from solid or for instance cast profiles, which are heavy and on which separate connecting means have to be arranged for mutual connection and for arrangement of the fabric element.
BRIEF SUMMARY OF THE INVENTION
The present invention has for its object to provide a device wherein at least the above-stated drawbacks are obviated, and a device is provided for this purpose which is distinguished in that the wall-mounted frame and the hanging frame are each formed from at least one hollow profile and at least one open profile, wherein the hollow profile and the open profile form a unit.
In a device according to the present invention, it is thus possible in simple manner to combine the hollow profile, which serves to provide sturdiness and robustness, with the open profile, which serves to provide space for said connecting means which can engage in the cavity of the open profile, whereby assembly of a device according to the present invention is greatly simplified. As a result of said configuration, use can be made of aluminium, for instance by means of extrusion, whereby a sufficiently sturdy but very light entity is obtained. Uniformity of the profiles of the hanging frame and the wall-mounted frame is moreover increased, whereby the number of components to be used is considerably reduced.
In a preferred embodiment a device according to the present invention has the property that the open profile comprises a C-shaped profile. Access for the connecting means is herein provided in the open part of the C-profile for engagement therein.
Another embodiment of a device according to the present invention has the property that the hollow profile is connected at a distance from the open profile to an additional open profile. In this manner a component forming part of the wall-mounted frame or the hanging frame is provided with measures for connection to at least two other components. The device in this embodiment preferably has the property that the hollow profile and the additional profile form a unit, just as the hollow profile and the initial open profile as already noted above. The simplicity of the components to be used for the device is hereby increased, as is the uniformity. It is also the case here that the frames to be thus formed are manufactured from extrudable profiles of aluminium, at a relatively low cost price, a low weight, a long lifespan and other advantages. Such a device preferably has the property that in cross-section the additional open profile covers more than a semi-circle, the diameter of which is greater than a diameter of a string member around which the fabric element is fixedly arranged, wherein the string member with the fabric element therearound is slidable into the additional open profile. This enables an exceptionally simple assembly which saves time and cost. In preference the string member is herein substantially as long as the additional open profile, so that for each profile of one of the two frames the fabric element as connection therebetween ensures in any case a very simple assembly.
In a further preferred embodiment a device according to the present invention has the property that the additional open profile is flanked by a rainwater discharge arranged toward the outside relative to the fabric element. This applies particularly to the wall-mounted frame, but possibly also for the horizontal profiles of the hanging frame on the top side thereof. Water dripping or trickling downward or forward along the outside wall or possibly along the fabric element is thus prevented from flowing over the fabric element on the top of the device and then still causing inundation of water onto the rear of a vehicle or at the shed entrance. The rainwater discharge is preferably formed by a gutter shape in the material of the hollow profile which extends toward the interior thereof. The rainwater discharge is in this way formed as integral part of the hollow profile, so that it can be designed in simple manner in the extrusion process of for instance aluminium as a unit with the other parts of the profiles for both frames.
Other properties of a device according to the present invention as stated explicitly in the dependent claims will also be further elucidated on the basis of the figure description following hereinbelow.
