Definitions

• Connection system for a cloth or the like method for connecting a cloth or the like to an element and new use of half a zipper provided on the side edge of a cloth or the like .
• the present invention concerns a connection system for a cloth or the like, such as for example for a cloth for roller blinds, a facade cloth or facade sail cloth, a film, either or not printed, and the like.
• a cloth or the like should be interpreted in the broadest sense, including sailcloth, fleeces, fabrics, foils, films or combinations thereof, for indoor and outdoor use, regardless of the way in which they are made and regardless of the materials from which they are made.
• a cloth should often be connected to an element such as a profile or a frame or the like.
• the cloth for example a rectangular piece of cloth, to be connected to a roller tube on one side edge, while the opposite side edge is provided with a profile or the like which gives the necessary weight to the cloth to ensure a smooth appearance when the roller blind is unrolled .
• the profile is commonly connected to the curtain cloth by providing a border on the side edge concerned of the cloth over the full width in the form of a hem, in which a so-called string is passed.
• a profile which has a channel-spaced room in which the hem with the introduced string can be inserted, for example by sliding it in along an open crosscut end.
• a restriction or disadvantage of this solution is that the connecting line, often a seal, of the hem remains visible, also after the string has been provided in the profile.
• connection systems are required as well.
• the cloth is usually connected to the frame by providing the cloth with rivets or reinforcement rings along the circumferential edge.
• Such a fixed structure consists for example of a tubular framework which is connected to a fagade or a scaffolding.
• a disadvantage of such a connection for cloths or the like is that the cloth is attached at discrete points and possibly tightened, as a result of which deformations occur in the cloth surface.
• the embodiment with half a zipper prevents a sun blind fabric from rattling during heavy wind gusts.
• the half-zipper contains discrete blocks positioned at a regular mutual distance.
• the half-zipper is usually connected to the cloth by means of a seal.
• the half-zipper is provided in an inner space in a first section which is delimited by a first jacket in which, over the entire length of the first section, is provided a first slot.
• the zipper can be led in the inner space along one of the crosscut ends of said first section, whereby the cloth extends through the first slot.
• the zipper blocks have a larger width than the width of the first slot, whereas the inner space in the first section provides enough space, such that the zipper can be moved up and down through the section without too much resistance.
• This first section is in turn spring-mounted towards the outside in a second section which is solidly fixed to the building, in such a way that the two opposite sections are at all times pushed away from each other.
• This second section comprises a channel-shaped chamber delimited by a second jacket provided with a second slot, in this case a wide one, through which the cloth is guided.
• the first section is provided in the second section with both slots close to each other, i.e. such that the cloth between the opposite half-zippers forms a plane in view of a smooth up-and-down guiding.
• the resilience is limited or even absent, however, when the cloth remains unloaded, for example in still air, such that the cloth can thereby be rolled on and off without too much resistance .
• This balancing exercise results in an assembly which is able to resist forces which occur in case of conventional wind strengths on roller blind surfaces which are not too big.
• roller blind surface increases, or when another application is aimed, such as for example cladding a fagade with textile, the forces will increase quadratically with the length.
• connection system for a cloth or the like
• the invention concerns a connection system for a cloth or the like, which connection system can cooperate with a cloth, of which at least a part of an edge is provided with what is called a half-zipper, whereby the connection system comprises at least a first section provided with a first jacket defining a first inner space, but which first jacket is provided with a first slot over substantially the full length of the first section, whereby the first inner space is carried out suitably, such that the half-zipper can be introduced in it while the cloth or the like can extend through the first slot, and which first section can cooperate with a channel-shaped chamber provided in an element with which the cloth is intended to be connected, such as for example a second section or the like, which channel-shaped chamber is delimited by a second jacket defining a second inner space, but which second jacket
• the cloth or the like can extend through the second slot, and in such a way that when a tensile force is exerted on the cloth or the like, the first section will be partly tilted if need be, but whereby a complete reversal of the first section in the channel-shaped chamber, i.e. such that the first slot ends up in line with or in the vicinity of the second slot, is prevented.
• the channel- shaped chamber and/or the half-zipper is/are part of the connection system according to the invention.
• the technical result is obtained among others when the largest diameter of the cross section of the first section, i.e. the largest distance that can possibly be measured between two points situated on the outside of the first section, is not smaller than the diameter of the largest virtual circle that can be drawn in cross-section in the channel-shaped chamber.
• the geometry and dimensions of the first section are adjusted in such a way to the geometry and dimensions of the channel-shaped chamber that, when exerting a tensile force on the cloth or the like, the first section is partly tilted, in any case over less than 180°, preferably over less than 90° or even over less than 70°, whereby the tilting results in the first section being blocked in the channel-shaped chamber.
• the shape of the channel-shaped chamber may for example be mainly oval without any substantial slot depth.
• a first section according to the invention which can cooperate with such a channel-shaped chamber which is oval- shaped when seen in cross-section can be either oval or substantially rectangular, of course roughly smaller than the channel-shaped chamber, and with the largest diameter of the first section, for example the distance between the first slot and the opposite wall part on the outside of the first section, being larger than the provided width in the channel-shaped chamber.
• the shape of the channel-shaped chamber in cross-section can for example comprise a circular portion, complemented with for example a rectangular slot as seen in cross- section having a slot depth amounting to for example one third of the total depth of the channel-shaped chamber.
• this basic form is referred to as a tree-shaped cross-section.
• a first section according to the invention which can cooperate with such a channel-shaped chamber which is tree- shaped when seen in cross-section may also comprise a predominantly circular portion with an interruption so as to form the first slot, and opposite the first slot it may be provided with a protruding fin on the outside which, when attached, takes up a place in the second slot of the channel-shaped chamber.
• the present invention also concerns a method for connecting a cloth or the like to an element, which method, starting from a cloth with a half-zipper connected thereto on the one hand, and an element with which the cloth is to be connected, which element is provided with a channel-shaped chamber which is delimited by a second jacket defining a second inner space, but which second jacket is provided with a second slot over substantially the full length of the channel-shaped chamber on the other hand, consists of the steps of providing a first section with a first jacket defining a first inner space, but which first jacket is provided with a first slot over substantially the full length of the first section, whereby the half-zipper is inserted in the first inner space while the cloth or the like extends through the first slot, after which the first section is provided in the channel-shaped chamber, in particular with the first slot in or near the most hidden part of the channel-shaped chamber, i.e. in the zone of the channel-shaped chamber away from the second slot, while the cloth or the like passes through the second slot.
• the present invention also concerns the new use of a half- zipper provided on the side edge of a cloth or the like, which use concerns the realisation of a connection without the half-zipper having to be led in the first section.
• FIGS. 1 to 3 are cross-sections of three alternative embodiments of a connection system according to the invention .
• Figure 1 schematically represents a cross-section of a connection system according to the invention, with a first section 1 in which the half-zipper 2 which is connected to the edge of a cloth 3 has been introduced.
• the whole is appropriately provided in a channel-shaped chamber 4 in element 5.
• the element 5 in this case concerns a schematically represented section 5.
• the half-zipper 2 comprises discrete blocks positioned at a regular mutual distance.
• the half-zipper 2 is connected to the cloth 3 by means of a weld or seal 6.
• the first section 1 is provided with a first jacket 7 which has an essentially round or circular design here and which defines a first inner space 8, but which first jacket 7 is provided with a first slot 9 over substantially the full length of the first section 1.
• the first inner space 8 is made such that the half-zipper 2 can be introduced in it while the cloth or the like 3 can extend through the first slot 9.
• the first jacket 7 is provided with a protruding fin 10 on the outside, in this case in particular opposite the slot 9, which fin 10 is part of the first section 1.
• the half-zipper 2 can be applied for example via one of the crosscut ends of the first section 1, while the first slot 9 has a width which is smaller than the width of the discrete blocks of the half-zipper 2 in order to prevent a too rapid exit.
• the channel-shaped chamber 4 in the element 5 is delimited by a second jacket 11 which defines a second inner space 12, but which second jacket 11 is provided with a second slot 13 over substantially the full length of the channel- shaped chamber 4.
• the shape of the channel- shaped chamber 4 has a round compartment 14 and a chamber 15 which is rectangular when seen as a cross-section, i.e. the slot 13 which has a considerable slot depth here, namely between one third and half of the total depth of the channel-shaped chamber 4.
• this basic shape is referred to as a tree-shaped cross-section.
• the width of the second slot 13 is in this case, but not necessarily, smaller than the smallest diameter of the first section 1.
• the geometry and dimensions of the first section 1 are adjusted such to the geometry and dimensions of the channel-shaped chamber 4 that the first section 1 with introduced half-zipper 2 and extending cloth or the like 3 can be provided in the channel-shaped chamber 4, in this case given the smaller slot width as compared to the smallest diameter of the first section 1, via one of the crosscut ends of the channel-shaped chamber 4.
• the first section 1, while being introduced or placed in the channel-shaped chamber 4, is placed with the first slot 9 in or near or at least predominantly in the direction of the most hidden part of the channel-shaped chamber 4.
• the most hidden part of the channel-shaped chamber 4 is meant the zone of the channel-shaped chamber 4 situated away from the second slot 13.
• first section 1 with the introduced half-zipper 2 with which the cloth 3 is connected is being introduced or provided, the cloth 3 is guided between the second jacket 11 and the first section 1 to leave the element 5 further via the second slot 2.
• the geometry and dimensions of the first section 1 are additionally adjusted such to the geometry and dimensions of the channel-shaped chamber 4 that the first section 1, once it has been introduced as mentioned above, is not offered the space required to rotate such that the first slot 9 would be directed to the second slot 13.
• the geometry and dimensions of the first section 1 are adjusted such to the geometry and dimensions of the channel-shaped chamber 4 that, when exerting a tensile force on the cloth or the like 3, the first section 1 is partly tilted if need be, but whereby a complete reversal of the first section 1 in the channel-shaped chamber 4, i.e. such that the first slot 9 ends up in line with or in the vicinity of the second slot 13, is prevented .
• the largest diameter D of the cross section of the first section i.e. the largest distance that can possibly be measured between two points situated on the outside of the first section 1, is not smaller than the diameter of the largest virtual circle that can be drawn in cross-section in the channel-shaped chamber 4.
• the bottom line in the embodiment as discussed above and as represented in figure 1 is that the distance between the free end of the fin 10 and the opposite outside of the first jacket 7, i.e. near the first slot 9, is larger than the diameter of the round compartment 14 of the channel- shaped chamber 4.
• the method for connecting the cloth or the like 3 to an element 5 according to the invention, and the operation of the connecting system according to the invention is as follows .
• the half-zipper 2 is introduced in the first section 1 via one of the open crosscut ends of the first section 1.
• the cloth 3 emerges from the first slot 9, and the first section 1 is substantially rotated 180° around its axis while the cloth 3 is being held in position.
• the cloth 3 is guided along the outer wall of the first jacket 7 and along the fin 10, to proceed further from there on in the extension of the fin 10.
• the first section 1 is introduced in the channel-shaped chamber 4, in the present embodiment along one of the crosscut ends of the channel-shaped chamber 4.
• the cloth 3 thereby goes through the second slot 13; the fin 10 and the leaning part of the cloth 3 partly take up a place in the chamber 15 which is rectangular from a cross- sectional view, i.e. the slot 13 which has a considerable slot depth in this case, and the first jacket 7 which has an essentially round or circular design here, together with the leaning part of the cloth 3 and the zipper 2 which has been inserted in the section 1 are introduced in the round compartment 14 of the channel-shaped chamber 4.
• the first section 1 When exerting a tensile force on the cloth or the like 3, for example by suspending the cloth 3, whereby the section 5 forms a weight at the bottom, the first section 1 will be tilted until the fin 10 leans against one of the walls which delimit the chamber 15 which is rectangular seen in cross-section. Any further tilting is thus prevented, as a result of which the hidden arrangement of the first slot 9, and especially of the seal 6 remains guaranteed.
• This arrangement guarantees in particular, given the tangential orientation of the tensile strength near the first slot 9, a greater resistance to tensile forces than if the first slot 9 were positioned in line with the second slot 13.
• the variant embodiment from figure 2 differs from the embodiment in figure 1 in that the shape of the channel- shaped chamber 4 is substantially oval, without any significant slot depth.
• the represented first section 1 which can cooperate with such a channel-shaped chamber 4 with an oval cross-section may be predominantly rectangular or oval, as represented.
• the shape of the first section 1 as represented in figure 1 can also be combined with the oval channel-shaped chamber 4 as represented in figure 2.
