Description

KNOT OF TENSION STRETCH CEILING

The invention relates to the construction industry and can be used in the field of creating tension planes, in particular, suspended ceilings.

The invention can be used to solve a double problem, on the one hand - creating additional tension on stretch ceilings and other tension structures, which are characterized, for example, by large areas and, as a result, create significant loads on structural elements to ensure the necessary flatness without sagging for long period of time, and on the other hand - to close the gaps between the canvas and the wall, or between the canvas and other adjacent canvas. The proposed solution provides a simple, convenient and ergonomic installation and reliable tension of the canvas, and also provides the ability to close the gap between the tension of the canvas and the wall or other adjacent canvas.

BACKGROUND OF THE INVENTION Stretch ceilings, as such, are well known and widely used in the premises of the various purposes. At the same time, there are two main types of fastening on the market for stretch ceilings: an arpunnaya system for installing stretch ceilings and a staple (wedge) system for installing stretch ceilings. Harpoon system is very common in the market. In the harpoon system, the stretch ceiling fabric needs to be pre-fabricated, namely, a special sealant, a harpoon, is welded around the perimeter of the canvas, cut to size. When installing the blade, the harpoon is fixed in the profile with the help of a lock (seal in the inner part of the profile), then a plastic or rubber insert is installed - a masking tape that covers the resulting technological gap. The main difference of the staple type of fastening from the harpoon system is that it does not imply a process of pre-production of the web. Wooden or plastic bead, which is a triangular seal that fixes the canvas stretch ceiling inside the profile, is a separate part of the design. Thus, the installation process is as follows: cut the canvas from the roll with allowances, mount the wedge profile around the perimeter of the room, stretch the canvas and fix it in the profile with a bead. Next, cut off the excess fabric and install masking tape (decorative rubber or plastic seal).

The main disadvantage of both systems is the need to use masking tapes or inserts, which, as a rule, look inaccurate, have irregularities due to the elasticity of the material, often require decorative cover, which leads to additional waste of both material resources and time.

For example, the technical solution disclosed in the Russian patent for invention Ns 2325490, published on 05/27/2008 (author and patentee Abdusamadov Gamzat Saygidahmedovich), which contains the “Stretched ceiling attachment unit”, is known. In this technical solution shown in FIG. 1A, a staple type of attachment is used. As the bead used fixing element.

The attachment of a stretch ceiling depicted in FIG. 1A comprises a base element, which is a cross section of a profile made in the form of four walls arranged to each other outside and inside at right angles, having the same thickness, forming a cavity with the inlet opening between two the most narrow walls, and having the widest wall, intended for fastening to the wall of a construction object with the help of mounting holes made therein. In the cavity of the base element has a locking element having a cross-section T-shaped profile with bends along the edges of the horizontal shelf, which are designed to rest with their ends into the inner sides of the narrowest walls of the base element, and serving to fix the stretch ceiling inside the base element, which is ensured by tightly pressing the film with the ends of the bent edges horizontal shelf fixing element to the inner sides of the narrowest walls. The vertical shelf of the locking element is made in the form of a handle, designed for ease of installation of this element in the cavity of the base element. Additionally, the mount contains a patch piece, made in the form of a cover mounted on the edges of the walls of the inlet, made in the base element, ensuring its overlap. The edges of the lid are made with flanging to abut the narrow walls of the base element from the inside.

As mentioned above, the disadvantage of this attachment is the presence of a highly unaesthetic inlet opening, which remains visible and requires the use of a lining in the form of a cover.

It is also known the solution disclosed in the Russian patent for invention Ns2463414 C1, published on 10.10.2012 (author and patentee Sergegelev Andrey Vladimirovich), in which the “Baguette for mounting a stretch ceiling” is presented. This solution involves the use of a harpoon system. The technical result in this solution is the absence of a visible gap between the mating canvases. Baguette for mounting the stretch ceiling is made in the form of figured profile with means of fastening cloths. The profile contains a base, ribs of different lengths and a central partition, forming two open cavities for the institution and fixing of two canvases. The base is fixed on the supporting surface. The ribs are set at an angle to the base. The partition is formed by at least one edge. The size of the ribs of greater length is selected so that both cans are supported on it. Thus, in this invention there is no gap, but between two different s canvases, i.e. This solution assumes the presence of two canvases, which is far from always desirable, moreover, just in most cases only one canvass is required, which makes it impossible to use this solution. It is also known the solution disclosed in the Russian patent for the invention N22040651 C1, published July 25, 1995 (author and patentee Fernan Scherrer), which presents “Suspended ceiling and its attachment points”. This patent discloses a suspended ceiling, including a stretched panel suspended by means of an edge bordering in the form of a hook or harpoon to supports, mounted on a wall or ceiling, made of vertical edges connected by a horizontal shelf of different height, forming an open down cavity for the restaurant from the bottom of the panel to provide its contact with the edge of a larger rib, installed from the side of the institution, and having a shoulder located inside the cavity for supporting the border, elements for fixing the support, Made in the form of a plate protruding beyond the horizontal shelf, and installed vertically or horizontally when fastening the support to a wall or ceiling, respectively, characterized in that the shoulder is made horizontal and placed on a rib of a lower height. This solution uses a harpoon system and has the same drawback as other solutions known from the prior art, namely, a purely decorative lining is required to cover the seam that remains between the fastener and the wall or between fasteners. It is also known “Device for fastening stretch ceilings from polymeric materials”, disclosed in the Russian patent for utility model Ns 161888, in which a device is presented that includes a fixing profile with a horizontal shelf and a harpoon with a head, while the fixing profile has two lower vertical edges, one of which is made with the possibility of junction to the wall, and the horizontal shelf with two lower vertical edges form a U-shaped cavity, inside which W

placed the body of the harpoon, the head of which is located outside the cavity, while the body of the harpoon interacts with the vertical edge by means of a fixing protrusion, characterized in that the inner part of the vertical edge of the fixing profile, made with possibility of abutment to the wall, is provided with main fixing protrusion and successively located auxiliary fixing teeth , while inside the U-shaped cavity formed by a horizontal shelf with two lower vertical ribs, is the body of the harpoon, it the one-sided protrusion and double-sided bevels on the end part, the one-sided projection of the harpoon interacts with the main locking protrusion on the surface of the vertical rib, while in the conjugation of the harpoon's body with its head a groove is made, and above the U-shaped cavity a closed cavity of rectangular section is made. As is clear from the description, the device involves the use of a harpoon system. Utility model s 161888 selected as the closest analogue in relation to the proposed in this application technical solution.

The disadvantages of this technical solution presented in FIG. 1B, it is limited only by the harpoon system, as well as the impossibility of ensuring that the harpoon is reliably pressed against the wall due to the impossibility of absolutely accurate observation of the dimensions of the various elements of the device, and the same because of the unevenness of the wall, which are almost always present in any room. Moreover, with the help of such a solution, it is impossible to ensure the fit of the stretch ceiling fabric to the wall if the wall passes at an angle to the vertical plane, which happens when using non-standard architectural and technical solutions. Thus, this device has the same drawback as other devices known from the prior art, namely, the inevitable presence of a gap between the edge of the web and the wall, requiring subsequent closure with decorative elements.

Also, the lack of a technical solution disclosed in the above utility model Νδ 161888 is the inability to use the mounting tool for the establishment of the harpoon in the appropriate cavity. In this well-known system, the installation of the ceiling and its tension are performed simultaneously, which requires considerable effort on the part of installers, while the installation process itself is so inconvenient that it requires the participation of up to three people at a time. Experts have long needed a system in which, after installation, there would be no technological gap, and therefore there would be no need to use decorative elements, in particular masking tape, as well as which would provide convenience and ease of use. The invention proposed in this application is simple and ergonomic to use, allows you to completely eliminate the shortcomings of the solutions of the prior art and to ensure a tight fit of the canvas of the stretch ceiling or other tensile structure to the wall or to the counter canvas with simultaneous additional spring-loaded tension of the tension structure, in particular the stretch ceiling.

EMBODIMENTS OF THE INVENTION FIG. 2A-2D, an embodiment of a tension ceiling tension assembly is shown, in which the support profile is a tension ceiling mounting assembly with a cavity for fixing the edge of the stretch fabric web. These figures show the successive stages of mounting a stretch ceiling. FIG. 2A-2D, a stretch ceiling tension assembly 1 is shown, which contains a supporting profile 2, having one edge, designed to fix the profile 2 on the wall, and a cavity 3 open on one side for fixing the edge of the canvas of the stretch ceiling. The node 1 also contains a clip 4, which in this case is designed to be mounted on the support profile in a detachable manner. The clip 4 has a curved shape in cross section, convex from the supporting plane, with two edges, one of which is a connecting edge 5, designed to attach to the supporting profile, and the second - the clamping edge b, is intended for pressing with the springing of the canvas 7 of the stretch ceiling to the wall. In this case, the clip 4 can be in two basic positions — in the mounting position, as shown in FIG. 2B and 2C, and in the locked position, as shown in FIG. 2D

In the mounting position, the clip 4 provides free access to the cavity 3, for fixing the edge of the canvas of the stretch ceiling, allowing the edges of the stretch ceiling to enter the cavity 3, as shown in FIG. 2C. After inserting the edge of the stretch ceiling into the cavity 3 and fixing it there using a harpoon or staple system, the clip 4 is transferred from the mounting position to the locked position, as shown in FIG. 2D, in which the clip, firstly, is securely fixed, and secondly, presses the canvas 7 of the stretch ceiling to the wall without a gap between the canvas and the wall. and Fixing the clip in the locked position can occur in several ways. In particular, as shown in FIG. 2C to 2D, the carrier profile 2 comprises an open cavity 8 on one side. In this case, the connecting edge 5 comprises a locking protrusion 9 allowing the clip 4 to freely enter the locking cavity 8. When translating the clip 4 from the mounting position shown in FIG. 2B and 2C to the locking position shown in FIG. 2D, locking protrusion 9 is clamped by the walls of the locking cavity 8, ensuring reliable retention of the clip 4 in this position.

Another option of reliably holding the clip 4 in the locking position involves the presence of sawtooth projections 10 on the clip surface facing the carrier profile, as shown in FIG. 2, FIG. 3, FIG. 4 and FIG. 5. Due to these sawtooth protrusions 10, the clip 4 in the locked position is securely fixed and presses the web of the stretch ceiling tightly to the wall surface.

In addition, in another embodiment, as shown, for example, in FIG. 3, the surface of the carrier profile in contact with the clip contains one reciprocal saw-tooth protrusion 11, which increases the reliability of holding the clip 4 in the locked position.

In yet another embodiment, as shown in FIG. 2, FIG. 4 and FIG. 5, the surface of the carrier profile, in contact with the clip, contains several reciprocal saw-tooth protrusions 11, which further increases the reliability of holding the clip 4 in the locked position.

In the embodiment shown in FIG. 3, the connecting edge 5 has two locking protrusions 9. When transferring the clip 4 from the mounting position to the locking position, the clip is held both by locking the projections 9 and by sawtooth protrusions 10 on the surface of the clip that faces the carrier profile double fixing, increasing, thus, reliability of a design. An embodiment is possible in which the joint edge has only one locking protrusion 9, for example, as shown in FIG. 4 and in FIG. five.

Due to the versatility of its design, the proposed tension assembly 1 can be installed both on a vertical surface, for example, on a wall, and on a horizontal surface, for example, on the ceiling, as shown in FIG. five.

As was shown above, the connecting edge 5 can provide a detachable connection of the clip 4 with the supporting profile 2, but it is also possible that the connecting edge 5 is attached to the supporting profile 2 in one piece, for example, glued to it, welded, or initially made as one piece with bearing profile.

Such an embodiment of the invention is shown in FIG. 6A to 6C, where the connecting edge 5 is permanently attached to the carrier profile 2, i.e. the clip 4 and the carrier profile 2 are made as one unit.

In this embodiment, shown in FIG. 6A to 60, bearing the profile 2 of the tension assembly 1, is made in the form of a lining 12 intended to be attached to the tension ceiling attachment assembly 13. As seen in FIG. 6A, the stretch ceiling mounting unit 13 contains two vertical fins 14 defining, on the one hand, a plane for fastening to the wall, and, on the other hand, a supporting surface for fastening the supporting profile 2 in the form of a lining 12. One of the vertical fins 14 is opposite to the supporting one profile 2 is made with the possibility of junction to the wall, and the node 13 for fastening the stretch ceiling also has a horizontal shelf 15 (Fig. 6C), forming with two vertical ribs 14 a U-shaped cavity 3, inside of which a harpoon is placed (Fig. 6B). Above the U-shaped cavity is a closed cavity of rectangular section, designed to pass through it a fastener, in this case a self-tapping screw 16, also used for fixing the carrier profile 2 in the form of a lining 12 on the node 13 of the fastening of the stretch ceiling.

In this embodiment, the clip surface facing the carrier profile includes sawtooth protrusions 10, and the surface of the carrier profile contains responsive sawtooth protrusions 11, which increases the reliability of the clip 4 and the tightness of the stretch ceiling to the wall in the locked position.

As seen in FIG. 6C clip 4 is made with the possibility of departure of the clamping edge b for the plane of the wall on which is mounted the mount 13 of the stretch ceiling in the locked position. Thanks to this technical solution, the tension of the stretch ceiling cloth against the wall is tight without a gap, even if the wall does not pass strictly vertically along the stretch ceiling attachment attachment 12 of the stretch ceiling attachment 12, and possibly at a significant angle, which allows for the implementation of complex and original architectural technical solutions.

Also, as shown in FIG. 7, as one of the measures to ensure an improved fixation of the tension ceiling assembly, the mounting hole 17 for fastener 18 is closer to the center of the supporting profile 2, which provides a more equilibrium distribution of loads in the structure when it is attached to the bearing surface, which, as a result, provides higher performance characteristics of the structure.

FIG. 8 shows an embodiment of a tension assembly 1 for use in a construction with a two-level stretch ceiling. In this embodiment, the carrier profile 2 contains two cavities 3 and 3 'open on one side and intended for fixing two multilevel webs 7 and T. In this embodiment, the clip 4 in the locking position presses the web 7 of the stretch ceiling located above to the vertical segment counter canvas 7 'stretch ceiling, the horizontal part of which is located below. In this case, in the depicted embodiment, both canvases are additionally pressed to the vertical portion of the carrier profile.

Thus, the problem of closing the gap between the bearing surface, in this case the wall surface, and the attachment unit of the stretch ceiling is successfully solved.

Obviously, the option of creating a two-level ceiling may assume the implementation of the carrier profile 2 in the form of a lining 12, while these open cavities 3 and 3 'open on one side can be made on the tension ceiling attachment unit 13. This option is not shown in the figures.

FIG. 9 shows an embodiment of the invention in which the locking protrusion 9 and the locking cavity 8 have a rectilinear shape in section, and their mating surfaces have a plurality of protrusions that securely hold the locking protrusion 9 in the locking cavity 8 in the locked position. When installing the ceiling, the clip 4 is first introduced into the installation position, in which the locking protrusion 9 is not fully inserted into the locking cavity 8, providing free access to the cavity 3 to install and fix the edge of the canvas of the stretch ceiling, after which the locking ledge 9 is inserted into the locking cavity 8 to end, providing additional tension on the canvas stretch ceiling and its pressure on the wall.

FIG. 10A and 10B depict an embodiment of the invention in which the stretch ceiling tension assembly 1 comprises a support profile 2 having a cavity 3 open on one side for fixing the edge of the stretch canvas 7 and represents the tension ceiling attachment unit. Node 1 also contains a clip 4, made with the possibility of detachable installation on the supporting profile 2. The clip 4 contains a connecting edge 5 containing locking protrusion 9 and providing attachment to the supporting profile 2, and the clamping edge 6, ensuring the pressing of the canvas 7 stretch ceiling to the wall when finding the clip 4 in the locked position. As seen in FIG. 10A and 10B cavity 3 for fixing the edge of the canvas stretch ceiling and the lock cavity 8 have a common entrance 19. The supporting profile 2 contains the lower curvilinear edge 20 and the upper curvilinear edge 21 defining the specified common entrance 19. The upper curvilinear edge 21 has at its end a hook bent down 22 ending with boss 23. At the same time, the locking protrusion 9 comprises a recess 24, designed to grip the boss and hold the clip 4 in the mounting position, as shown in FIG. 10A. This design provides special ease of installation, since the clip 4 provides free access to the cavity 3 in the mounting position for fixing the edge of the stretch fabric and at the same time does not interfere with the installation and fixation of the stretch ceiling, as it is securely held in place.

After installing the canvas ceiling in the cavity 3 through the inlet 19, the clip is transferred from the mounting position to the locking position shown in Fig.10B using the same input 19. To better hold the clip in the locking position, the interacting surfaces of the locking protrusion 9 of the locking cavity 8 have protrusions respectively, the surfaces of the locking protrusion 9 have projections 25 and the counter surfaces of the locking cavity 8 have projections 26. In FIG. 11A and 1B depict an embodiment of the invention in which the stretch ceiling tension assembly 1 comprises a support profile 2 comprising a cavity 3 open on one side for fixing the edge of the stretch fabric canvas 7 and constituting the tension ceiling attachment unit. The profile also contains a lock cavity 8 that is open on one side.

Node 1 also contains a clip 4, made with the possibility of detachable installation on the carrier profile 2. Clip 4 contains a connecting edge 5, containing locking protrusion 9 and providing attachment to the carrier profile 2, and the clamping edge 6, ensuring the pressing of the canvas 7 stretch ceiling to the wall when finding the clip 4 in the locking position. In this embodiment, the clip 4 has a rectilinear shape in section, and the locking protrusion 9, made on the connecting edge 5, has a section in the form of maces of protrusions on the surface interacting with the inner surface of the locking cavity 8, which, in turn, has reciprocal indentations on its inner surface interacting with the surface of the locking protrusion 9 in the locked position.

As seen in FIG. 11A, the clip 4 in the mounting position provides free access for mounting and fixing the canvas of the stretch ceiling, after which the clip 4 is rotated in the lock cavity 8 and transferred to the locked position, as shown in FIG. 11B, in which it is securely held by the protrusions on the surface of the head of the mace of the locking protrusion 9 and the recesses on the inner surface of the locking cavity 8. In this case, of course, the protrusions and recesses are interchangeable.

In general, depending on the chosen embodiment of the invention, the installation process is as follows. In the first step, install the carrier profile. As is clear from the above description, the carrier profile can be made in the form of a lining and mounted on the mount of the stretch ceiling, or it can itself be the mount of the stretch ceiling. Further, in the case of performing the clip with the possibility of detachable fastening on the supporting profile, the clip is inserted by inserting the connecting edge of the clip into the lock cavity of the supporting profile. In the case where the clip is attached to the support profile in one piece, this step is not required.

At this stage, the clip assembly is in the mounting position, providing access to the cavity for fixing the web of the stretch ceiling, which is made either in the external mount of the stretch ceiling or on the support profile itself.

Next, perform the fixation of the canvas (stretch ceiling PVC, fabric ceiling, advertising banners, etc.). At this point, set the main tension of the canvas. Further, if necessary, cut off the excess fabric. Then they transfer the clip to the fixing position and press the web against the corresponding surface (wall / other web, etc.). In some cases, the web may not press against another surface, but simply remove the web fixing unit from the field of view. Translation clips in the position of fixation is carried out by applying a force through the canvas to the clip.

The functionality of the proposed tensioning unit includes the overhead of the clamping edge in the locking position beyond the plane of the abutment wall, which allows to eliminate the mounting faults and / or compensate for the curvature of the specified abutment surface against which the web is pressed with the help of a clip. This functionality is provided by the flexibility and elasticity of the clip, which is ensured both by its shape and by the material from which it is made, in particular plastic or metal.

The technology can be applied in any systems where web stretching is applied (ceilings, walls, advertising structures, etc.).

The embodiments of the invention disclosed above should be considered as examples that do not limit the scope of patent protection, but only explain the features disclosed in the appended claims.
