Definitions

• the present invention relates to a device for protective- covering by way of canvas-sections, intended to be joined and stretched over beams, extending over a space-portion to be protective-covered.
• the objective of the present invention is to alleviate the above-mentioned problem and to provide a device for protective- covering enabling a joining without the risk of roof-drip and which allows a, from every point of view, favourable stretching of the canvas-sections.
• a device for protective-covering characterized in that the canvas-sections are provided with a longitudinal tension-element along at least one edge-portion adapted to extend in the longitudinal direction of a beam, which tension-element consists of a strip, string or similar, that said edge-portion is adapted to over ⁇ lap the adjacent edge-portion of an adjacent canvas-section, that said beams have a cross-sectionally concave, upwardly facing surface, defining a groove, in which said tension- element extends and that the tension-elements are adapted at the ends to be secured or alternatively connected to the respective ends of further tension-elements, so that the tension-elements can be stretched over the provided beams.
• Fig. 1 schematically shows a cross-section through a canvas stretched over a beam
• Fig. 2 shows a partially broken side-view of a protective-tent, built up with the device according to the invention
• Fig. 3 shows a cross-section through a beam-profile of the device according to the invention in a first embodiment
• Fig. 4 shows a second embodiment of the beam-profile
• Fig. 5 shows a cross-section through a jointing-profile for joining sections of beam-profiles according to Fig. 3 and Fig. 4 respectively,
• Fig. 6 shows a cross-section through two overlapping edge-portions of canvas-sections secured to the beam-profile according to the first embodiment
• Fig. 7 is a view of a number of canvas- sections jointed to each other and laid out in a schematically imagined position, whereby the beam-profiles have been excluded for the sake of clarity.
• Fig. 1 and 2 thus show an example of an embodiment of a protective-covering of a space-portion with a number of parallelly arranged beams 1 in the shape of archs for protective-covering a space-portion 2 under the beams.
• a canvas-material is stretched in the shape of several canvas-section 3, 4, 5, 6.
• the canvas-sections are so arranged, that they extend with two mutually parallel edge-portions 7, 8 in the longitudinal direction of the beams 1 and overlap the adjacent edge-portion 9, 10 of an adjoining canvas-section. The arrangement is described in greater detail with reference to Fig. 6.
• Fig. 3 shows the profile-shape of a beam-profile 1, which may have the arched shape shown in Fig. 1.
• the beams may consist of straight sections, which are broken in at least one place, in order, for instance, to form a conventional saddle roof.
• the beam 1 has an upwardly facing surface 11, which to its shape according to Fig. 3 is concave and shaped with an arched contour-line in such a way that the profile defines the shape of a groove in the top face of the beam.
• the profile further has a cavity 12 with the shape of a T, defining a longitudinal track with a longitudinal opening 13, facing downwards.
• Fig. 4 shows an example of an alternative embodiment of the beam-profile 14, which differs from the first embodiment according to Fig. 3 by the fact that the concave surface, here denoted 15, has straight contour-lines with downwardly converging side faces 16, 17 and a straight bottom-contour 18.
• An example of an additional shape is the V-shape, where the bottom-face 18 no longer exists.
• the profile in the this second embodiment has the same T-shaped track as in the first embodiment.
• Fig. 5 shows a jointing-element 12a, with a T-shape, adapted to be inserted into the T-shaped track 12 in the beams 1 and 14 respectively.
• the jointing-element 18 is intended to join beam- sections by being inserted into the ends of the beams and to extend into two beam-section in order to hold these together.
• each canvas-section 3, 4, 5, 6 is provided, at least at one of its edge-portions 8, 10, with a longitudinal tension-element 19, 20 for example in the shape of a strip made of a strong material, for example a woven strip of synthetic fibre thread.
• each canvas-section has two parallel edge- portions, namely the ones positioned along the mutual parallel beams 1, provided with tension-strips 19, 20.
• the strips are as an example sewn to a respective canvas-section 3, 4, whilst the edge-portions 8, 10 of the canvas-sections overlap each other so that both strips 19, 20 run in the upwardly facing concave groove 11.
• the canvas-sections may additionally be provided, in a known manner, with a folded reinforcement-section 21, 22.
• the two edge-portions 8, 10 are not sewn together, but are held in position by the application of a tensile-force in the strips by stretching these forcedly in the longitudinal direction of the beams 1 and securing them at their ends.
• the concave groove forms a position guidance for the tension-strips against movements side-ways and also collects any penetrating rainwater, which in heavy rain may make it in between the edge- portions of the canvas-sections and the groove thus guides the rain water in the longitudinal direction of the beam and downwardly towards the lower ends of the beams.
• Fig. 7 schematically shows four canvas-section 3, 4, 5, 6 in a laid-out condition, although the beams have been removed for the sake of clarity.
• the tension-strips 8, 10, of which only the superposed tension- strip is visible advantageously have end-portions 23, 24, extending beyond the two opposite edge-portions 25, 26 of the canvas-sections, which extend transversally relative to the edge-portions 8, 10 along which the strips 19, 20 are attached.
• the ends 23, 24 advantageously are provided with fastening-element for fastening two interacting members on the beams.
• the tension-strips may for instance be provided at their ends with rings, for example a number of rings in a row at each end-portion, which may be hooked up in hook-like or pin-like elements jutting out from the beams in the concave groove 8 at the ends of the beams or beam-sections.
• the beam-profiles may have a completely different shape than the one shown.
• the T-shaped track may be excluded.
• the depth of the groove may be more accentuated with extending guiding edges, which, however, should be somewhat rounded in order to avoid abrasion of the canvas- material.
• the tension-elements may be in the shape of strings made of a synthetic material, steel wire or similar, which are sewn into channels formed by the canvas-material.
• the sections need furthermore not have a width which equals the interspaces between the two adjacent beams, but a canvas- section may naturally extend over several beams, but may thereby still be provided with tension-strips, so positioned, that the strips end up exactly overlapping the groove of the beams. It is naturally also conceivable that tension-strips are missing at those beams, where joining does not take place.
• the above-mentioned jointing-profile may, apart from joining, be used as a fastening device for posts or stays between the beams serving as roof-frames, or they may serve as other kinds of attachments.
