DETAILED DESCRIPTION
(20) FIG. 1A shows a schematic diagram of a rectangular, in particular square tent in diagonal view; FIG. 1B shows a kind of X-ray view of the area of the tent roof which is behind the screen 2. The tent roof 1 has a screen 2. At the respective end areas of the tent roof, the screen 2 overlaps the upper end 41 of the supports 4, which in turn are arranged in feet 3. The supports 4 are connected to the roof structure 44 having the shape of a scissor-type grid, which supports the roof of the tent. In addition, the corner protection device 5 in the area of the upper end 41 of the supports 4 is illustrated schematically. The arrows pointing to the left and to the right already indicate that the tension of the tent roof described in more detail with respect to FIG. 3 to FIG. 9 goes in the direction of the arrows.
(21) FIG. 2 shows a schematic diagram of the tent roof illustrated in FIG. 1 in plan view. In all four corners of the tent roof 1, supports 4 are arranged, which have a corner protection device 5. The corner protection device 5 is arranged between the fabric of the tent roof and the support 4. The arrows displayed in all four corners indicate the direction of the tensioning effect achieved by the invention.
(22) FIG. 3 to FIG. 5 show as schematic diagrams the structure of the corner protection device 5, which, in the diagram shown, also serves as a tensioning element 6 according to the first and second embodiment.
(23) FIG. 3 reveals the three-dimensionality of the corner protection device 5. The corner protection device 5 has a body comprising three essential areas. The corner protection device 5 has an overall shell-shaped configuration. In the shell-shaped configuration shown, the corner protection device 5 encompasses with its inner side the outer side of the support 4, which is illustrated in more detail in FIG. 7 and FIG. 8.
(24) It can be seen in the upper part of the corner protection device 5 according to FIG. 3 that it is configured there in the form of a tensioning element 6. The corner protection device has an outer side 49 and an inner side 50, but in this exemplary embodiment, the corner protection device has three elongated, vertically running segments 51, 52 and 53. The segments 51, 52 and 53 can form a unit in terms of material and design, but can also be separated in a slot-like manner. In the aforementioned shell-shaped configuration of the corner protection device 5, these segments are arrangedwhen viewed from aboveroughly in the form of a boomerang to one another, i.e. an approximately arc-shaped course of the corner protection device can be seen, with segment 52 showing the end face of this element, while the segments 51 and 53 are arranged laterally thereof.
(25) According to FIG. 3, this upper area of the corner protection device 5 is interruptedwhen viewed verticallyapproximately in its center by a hinge section 54, which has at least one notch 57. This configuration of the hinge section with the notch 57 ensures that the upper part of the corner protection device 5, which is configured in the form of the tensioning element 6 so as to be movable, can thus be moved in a predetermined and suitable manner towards the outer side of the upper part 41 of the support 4 not shown in FIG. 3 or can be moved away from this outer side as a result of the hinge section 54.
(26) Since the notch 57, in particular, causes a material weakening of the overall corner protection device, this component provides at least one reinforcing rib 55 for the internal connection to the support 4, 41 or a reinforcing ring 58 as compensation.
(27) In addition, FIG. 3 shows the lower part 59 of the corner protection device 5. As can also be seen in FIG. 6, FIG. 7A and FIG. 7B as well as FIGS. 16A, B, C, it receives the fastening element 7, or the latter is arranged in area 59 on the corner protection device 5. The part 59 is not movable towards or away from the support 4, 41.
(28) Furthermore, FIG. 4 shows the aforementioned illustration in front view. The corner protection device 5 can be seen together with the tensioning element 6. In addition, it can be seen that the hinge arrangement 54 has three notches 57 and two reinforcement rings 58 in this exemplary embodiment. In the center of the hinge section 54, a recess 56 for receiving a rivet can be seen. By means of this rivet, the corner protection device 5 is connected to the upper part 41 of the support 4 of the tent roof 1. For this purpose, the upper part 41 of the support 4 has an opening at the corresponding point of the recess 56, through which the rivet can pass and is firmly connected to the inner side of the hollow support 4 in a manner customary in riveting technology.
(29) FIG. 4 also shows the lower part 59 of the corner protection device 5.
(30) The corner protection device 5 is also shown in FIG. 5 in side view. Above the hinge section 54, the provided tensioning element 6 can be seen, which merges into a spatial-geometrical enlargement at its upper end, namely into the tensioning element head 61. This tensioning element head 61 is shown in more detail in FIG. 7A, FIG. 7B and FIG. 9 in its interaction with the tensioning device 9.
(31) The hinge arrangement 54 with the recess 56 for a rivet can again be seen beneath the tensioning element area 6. The lower part 59 of the corner protection device 5 runs beneath it.
(32) FIG. 6 shows a schematic diagram of the arrangement of the corner protection device 5 arranged on the upper part 41 of the support 4 in front view.
(33) FIG. 6 shows the presence of a cover 42, by means of which the tensioning device 9 is protected from weather influences and dirt. In FIG. 6, the tensioning device 9 is covered due to the concealed view of the corner protection device 5; the arrangement of the tensioning device 9 beneath the cover 42 can be seen in side view in FIG. 7A and FIG. 7B.
(34) It can also be seen in FIG. 6 that the corner protection device 5 has a tensioning element 6. In the area of the hinge section 54, three notches 57 can again be seen, which are also marked in FIG. 5 in the side view of the corner protection device.
(35) The hinge section 54 is also marked in FIG. 6 by two reinforcement rings 58 shown.
(36) The lower part 59 of the corner protection device 5 also receives the fastening element 7, which can be recognized as a corner bracket 71 in the concrete illustration. It can also be seen that the corner protection device 5 is arranged vertically on the outer side of the upper area 41 of the support 4.
(37) In the area of the cover 42, further structural configurations for fastening this area to the supporting structure of the tent roof can be seen, with this fastening being of no relevance for the present invention.
(38) FIGS. 7A and B show the arrangement and configuration of the tensioning device 9, the corner protection device 5, the tensioning element 6 as well as the fastening element 7 in side view. The tensioning device 9 can be seen in detail in FIG. 7 as well as in FIG. 9. FIG. 7A shows the situation with the tensioning element head retracted and FIG. 7B with the tensioning element head extended.
(39) The tensioning device 9 is arranged on the outer side of the upper section 41 of the support 4, as can be clearly seen in FIGS. 7A and 7B. The corner protection device 5 is fastened to the upper section 41 of the support 4 in the area of the hinge section 54. Reference numeral 43 shows a rivet counter-holder on the inner side of the support 4, by means of which a fixed rivet connection to the rivet is made, which is inserted into the recess of the corner protection device 5 shown in FIG. 4 and FIG. 5 through the latter and guided to the rivet counter-holder through a corresponding opening in the support 4.
(40) In FIGS. 7A and 7B, the notch 57 in the area of the hinge section 54 can also be seen, through which the corner protection device 5 is given bending flexibility in this area. Therefore, the upper part of the corner protection device 5 can be moved or bent away from its original position in the direction of the arrow shown in relation to the outer side of the upper part 41 of the support 4 to the required extent. Due to the movable configuration of this part of the corner protection device 5, the latter thus assumes the function of the tensioning element 6.
(41) The movement of the tensioning element 6 away from the vertical axis of the support 4 as shown in a comparison of FIG. 7A with FIG. 7B is achieved by the tensioning device 9, which is illustrated in FIGS. 7A and 7B and in detail in FIG. 9. According to these two figures, the tensioning device 9 has a housing 91, which can be placed on the end area of the upper part 41 of the support 4 by means of a downwardly extending frame projection 95 and, if desired, fastened by further measures. The housing 91 contains an opening running horizontally, into which a spring 92 is inserted. The spring 92 acts on a pressure element 93. For this purpose, this pressure element has a collar 94, on which one end of the spring acts. In this embodiment, the pressure element 93 is configured in the form of a bolt. The pressure element 93 acts on the spatial-geometrical enlargement of the tensioning element 6, with this enlargement 61 being provided in the form of a tensioning element head. FIG. 7A shows an ideal initial state, in which the fabric of the tent roof is (still) in close contact with the support 4 so that the spring 92 has not yet or essentially not yet pressed the pressure element 93 against the tensioning element head 61, which, like the pressure element 93, thus assumes a state in which it is retracted into the housing 91. The spring tension presses the pressure element 93 against the tensioning element head 61. As a result, the tensioning element 6 and its tensioning element head 61 press against the tightly fitting fabric of the tent roof 1 in its original tension. If this tent roof expands due to ambient conditions and/or material fatigue, this configuration causes a post-tensioning of the tent roof, which is marked with reference numeral 12 in FIG. 7B.
(42) In order to prevent the fabric of the tent roof from evading the effect of this compressive stress, the fabric, in particular when configured in the form of a screen, is fastened to the lower part 59 of the corner protection device 5 by means of a fastening element 7. In the embodiment as described, the fastening element 7 is configured in the form of a corner bracket 71. For this purpose, the fabric of the tent roof, in particular the fabric of the screen, is fastened in an appropriate manner between the inner side of the fastening element 7 and the outer side of the lower part 59 of the corner protection device. As a result, a counter-stress of the fabric is maintained, i.e. the fabric cannot evade the effect of the compressive stress due to the interaction of the tensioning device 9 with the tensioning element 6, 61.
(43) The details of this arrangement can be seen in FIG. 8, which shows a schematic diagram of a plan view in the cross section of the support 4, 41 and the arrangement of the fastening element 7 on the corner protection device 5. Between the corner protection device 5 and the fastening element 7 configured in the form of a corner bracket 71, there is a clearance 8 in the form of a gap, in which the fabric of the tent is received. The fastening element 7 has a fastening member 72, which is provided with a barbed hook. The fastening member 72 passes through a corresponding opening of the corner protection device 5 and is fastened there by means of this barbed hook. This means that a coupling is achieved by engaging. Other options for fastening by means of screws, clamps, Velcro, snap fasteners, eye connections or any other fastening means are, of course, likewise possible.
(44) FIG. 10 shows the second embodiment of the present invention in sectional view. Here, a tensioning device 9 is also used, which implements the design principles described above and which interacts in the same way with the corner protection device 5 described above and the tensioning element 6, which is inserted into the hollow body of the support 4, 41.
(45) In this case, the tensioning device 9 either uses the internal space of the support 4, 41 as a housing 96, within which this embodiment is used, or the tensioning device is located inside a housing 91, which is inserted, for example pushed, into the hollow space of the support. In this embodiment, a corresponding opening is provided in the support, through which at least one spring 92 of the tensioning device 9 presses against the tensioning element 6 of the corner protection device 5 in a manner as has been explained in connection with the first-mentioned embodiment.
(46) Since the tensioning device 9 is arranged inside the hollow body of the support 4, 41, it is not necessary for the length of the body of the corner protection device 5 to protrude laterally beyond the upper end of the support 41 of the tent roof.
(47) FIG. 11 to FIG. 15 show the third embodiment, with FIG. 11 showing the corner protection device with the extended tensioning device and FIG. 12 showing the corner protection device with the retracted tensioning device, and FIG. 13 disclosing the tensioning shell, FIG. 14 the opening for the tensioning device in the corner protection device and FIG. 15 the opening for the tensioning device covered by means of the tensioning shell as well as the corner protection device.
(48) In this third embodiment, the tensioning device 9 is an integral component of the corner protection device 5.
(49) The corner protection device 5 is fastened to the support 4, 41 in a manner appropriate in terms of construction. The corner bracket 7, 71 for the fabric of the tent roof is arranged at its lower end 59.
(50) This third embodiment shows that the tensioning device 9 is no longer a direct structural component of the support 4, 41 of the tent, but part of the corner protection device 5 itself.
(51) The corner protection device 5 is attached and fastened to the support 4, 41 of the tent. At its lower end 59, a corner bracket 7,71 is attached to the corner protection device 5.
(52) At the point where the screen 2 of the tent fabric overlaps the corner protection device 5, an opening 65 is provided in the corner protection device 5, which receives the tensioning device 9, cf. FIGS. 11, 12, 14. For this purpose, the tensioning device 9 is arranged on the inner side 50 of the corner protection device 5, hence adjacent to the outer side of the support 4, 41.
(53) The tensioning device 9 preferably protrudes through the opening 65 in the corner protection device 5 in the direction of the fabric of the tent roof. In this example, the opening 65 preferably has a rectangular configuration so that more than one spring of the tensioning device 9 can pass through it. If a plurality of springs is used, a more even distribution of pressure on the fabric of the tent roof, which overlaps the corner protection device 5 in this area, is achieved in this way.
(54) For example, five springs 92 are arranged side by side in FIG. 11 and in FIG. 12. The springs 92 are arranged in an analogous manner on one side thereof in the tensioning device 9 and end at their other end, which is directed towards the fabric web, in corresponding pot-shaped receptacles 64, which serve to hold these ends of the springs and which in turn are arranged in a tensioning shell 62, as can be seen in FIG. 13. This tensioning shell is thus open towards the springs, while it has a smooth, closed surface 63 towards the fabric of the tent roof.
(55) The springs 92 thus press into the pot-shaped receptacles 64 of the tensioning shell 62, which in this way presses with its smooth, closed surface 63 against the screen 2 of the fabric of the tent roof. This results in a visually even tension of the fabric of the tent roof.
(56) Altogether, the functional principle can be described in such a way that the springs together with the tensioning shell are more or less retracted in the corner protection device 5 in their original state, FIG. 12, and thus create a smooth surface of the corner protection device 5 in the area of its opening. If the fabric of the tent roof expands, the springs with the tensioning shell extend out of their holder, FIG. 11, and press against the fabric of the tent roof, thereby causing it to be permanently and evenly tensioned.
(57) In this third embodiment, it is clear that the corner protection device itself does not have to be configured so as to be partially movable, as has been described, for example, for the previous embodiments, because it is not the corner protection device itself which moves against the fabric web of the tent as a result of the pressure of the springs, but because this function is performed by the configuration of the springs with the tensioning shell described above.
(58) The group of FIGS. 16A, B, C and D shows a further embodiment of the fastening element 7, which has a polygonal shape.
(59) FIG. 16A shows an overall view, from which the arrangement of the support 4, 41, the lower part 59 of the corner protection device 5 and the arrangement of the fastening element 7 can be seen. The tent fabric 1 of the tent is fastened to the upper side of the fastening element 7, as can be seen in FIG. 16C when viewed from the inner side. This results in the sandwich-like structure.
(60) The fastening element 7 is configured in the form of a plastic part 73, which can be fastened, for example sewn on, to the inner side of the fabric of the tent roof 1, in particular to the inner side of the screen 2 (FIG. 1) of the tent roof 1, cf. FIG. 16C. On its side facing away from the fabric of the tent roof 1, the sewable plastic part 73 is connected to the lower part 59 of the corner protection device 5 (FIGS. 16B, 16C).
(61) In this embodiment, the connection of the fastening element is configured in such a manner that the plastic part 73 has a hook corner clip 74 approximately in the center, which is inserted through a corresponding opening 60 in the lower part 59 of the corner protection device 5 and which hooks there on the inner side 50 of the lower part 59 of the corner protection device 5; for this purpose, the hook corner clip 74 has snap-in counter-latches 75, 76 (FIGS. 16B, 16C). Furthermore, the plane 77 of the surface of the plastic part 73 can be seen in FIGS. 16A and 16E. FIG. 16E shows the corner clip 74 from its inner side with the hook 78 bent inwards and the counter-latches 75, 76, which are inserted through the opening 60 of the lower part 59 and hook there on the inner side.
(62) In addition, it can be seen from FIGS. 16A, 16B and 16C that the fastening element 7 configured in the form of a plastic part 73 has a tongue-like hook 78 on its side which, when sewn on, is located at the bottom and which encompasses the lower end face 79 of the lower part 59 of the corner protection device so that further stabilization of the fastening between the tent roof and the corner protection device occurs.
(63) As can be seen from FIG. 16D, it is suitable with regard to fastening to hook in the tent roof 1 on the lower part 59 of the corner protection device 5, more precisely at the position 1, and then clip it into the opening 60. For this purpose, a recess 97 is provided for the hook 78 at the lower end face 79 of the part 59 so that the hook 78 can be fixed in a non-slip manner.
