Description

Technology area

The claimed technical solution relates to the field of construction, namely to parts of a stretch ceiling with harpoon fastening of its canvas to a profile, fixed along the edge of the ceiling to the adjacent wall of the room and providing placement of the canvas with an indent from the wall. The technical solution is intended for additional fixation of the stretch ceiling canvas in the profile while simultaneously hiding the technological edge of the canvas (the harpoon with the area of its connection with the canvas) from the view of an observer of the mounted stretch ceiling.

Prior art

Structures of stretch ceilings with harpoon fastening of the so-called "traditional" type (utility model patents RU 93422 (IPC Е04В 9/30, 2010), RU 135341 (IPC Е04В 9/30, 2013), RU 148231 (IPC Е04В 9/30, 2014), RU 179488 (IPC E04B 9/18, 2018) .In these designs, the overlay covers the gap between the edge of the stretched canvas and the mating surface (room wall). at the edge of the stretch ceiling. In this case, the profile has two walls - external and internal. The internal wall during the installation of the profile is in contact with the wall of the room, it is equipped in the middle with a step for the stop of the harpoon and continues further along the wall of the room to form a stop for the lining. a harpoon rests on the outer wall, the lower edge of the outer wall serves as a guide for the installed stretch ceiling fabric.

The practical implementation of the harpoon system for fastening the canvas of a stretch ceiling has as a disadvantage a weak retention of the harpoon in its cavity in the profile, frequent cases of the harpoon falling out of this cavity, especially with significant tension of the canvas when the harpoon is opened. Since the cover has an exclusively decorative purpose, it is not intended for fixing the stretch ceiling.

The edge of the outer wall that guides the fabric in most implementations has corners with a small radius of curvature, relatively sharp, which leads to the bending of the stretch ceiling fabric, the formation of folds and the fabric breakthrough.

Another disadvantage of the traditional type of fastening stretch ceilings is the overlap of the gap between the edge of the canvas and the wall. This leads to the need for careful preparation of a flat surface of the wall in the place where the lining fits. The snug fit of the lining to the wall reveals all the unevenness of the wall, if any.

The development of the method of fastening stretch ceilings was obtained in fastening the canvas with an indent from the wall, when a noticeable gap is left between the visible edge of the canvas and the wall. One of these mounts is called shadow mount. For it, for example, an open profile EuroKRAAB is used (https://www.potolokelite.ru/stati/naryazhnoy-potoiok-eurokraab.html). The shadow mount is characterized by the absence of an overlay, that is, a gap remains between the edge of the canvas and the wall of the room. This design eliminates the obstacle to using the mount on uneven walls - irregularities become invisible, small irregularities - invisible. In this case, the profile is made so that its inner part is less visible in the said gap. In this case, the profile, as for the traditional harpoon system, contains a cavity for accommodating the harpoon formed by the inner and outer walls. But the inner wall is made with an indent from the wall of the room and is made shorter - it ends with a ledge for the harpoon stop - so the wall is less noticeable.

The outer wall at the edge is equipped with a round edge in cross-section, which serves as a guide for the edge of the mounted stretch ceiling. The same side forms a stop on the inner side of the harpoon placement cavity. The border has a radius of rounding sufficient to prevent the formation of folds or rupture of the web, which occurs for the aforementioned analogs (RU 93422, RU 135341, RU 148231).

The inner and outer walls are inclined towards the wall to reduce the gap between the canvas and the wall.

In the above-mentioned fastening of the stretch ceiling using the EuroKRAAB profile, as well as with the traditional fastening, the disadvantage of weak holding of the harpoon in its cavity in the profile remains.

In the gap between the wall and the edge of the canvas, internal fasteners are still noticeable, especially at the outer corners of the room. The least aesthetic part of the stretch ceiling is the area where the harpoon joins the canvas.

The addition of illumination to the gap between the wall and the canvas led to the creation of the so-called floating fastening of the stretch ceiling. In one of these solutions (patent for utility model RU 203117 (IPC Е04В 9/18, 2021) the lack of visibility of the harpoon with the place of its welding with the web is eliminated. This solution contains a decorative plug (12) covering the cavity of the harpoon (2) (reference numbers according to RU 203117).

The disadvantage of this analogue is that for fastening the decorative plug, the profile must be equipped with an additional wall with a lock, passing over the inner wall with a ledge (3) for the harpoon stop. In this case, the decorative plug is attached to the aforementioned lock of the additional wall (above) and the rounded side of the outer wall (below).

In addition, the decorative plug, since it is decorative, does not clamp the stretch ceiling from below. Therefore, the utility model (RU 203117) has the disadvantage of weak retention of the harpoon in its cavity in the profile.

The closure of the cavity for placing the harpoon is also provided with a plug (utility model patent RU 204903 (IPC Е04В 9/00, 2021). The plug (10) is fastened by the plug (10) between the protrusion of the harpoon stop (6, 11) from above and the protrusion (11) from below on the lower edge of the outer walls of the cavity for placing the harpoon (reference numbers in accordance with RU 204903).

The disadvantage of this analogue is that for fastening the plug, the profile must be provided with a special protrusion from below, which increases the complexity and material consumption of the profile. This also does not allow the use of a plug for the well-known EuroKRAAB profiles.

In addition, the plug only closes the cavity for placing the harpoon and does not clamp the stretch ceiling from below. Therefore, the utility model RU 204903 has the disadvantage of weak retention of the harpoon in its cavity in the profile. The practical implementation of the plug according to patent RU 204903 made of soft material (rubber) leads to the fact that the plug is weakly retained on the lower projection through which the stretched web passes. The plug rests against the canvas and does not encircle the lower protrusion. In order for the plug to be held in the profile, it is necessary to push it further into the cavity where the harpoon is located. In this case, the plug is placed between the projection of the harpoon stop and the blade closer to the place where the harpoon is attached to the blade.

The analogue of RU 204903 is, by the totality of essential features, the closest analogue of the same purpose to the claimed technical solution. Therefore, it is accepted as a prototype.

Disclosure of the proposed technical solution.

The technical problem to be solved by the claimed technical solution is to provide additional retention to the harpoon of the stretch ceiling web in the profile.

The technical result provided by the claimed technical solution is the use of a detail that closes the cavity of the harpoon from the outside from the gaze, to increase the reliability of holding the web in the profile of the stretch ceiling with an indent from the wall.

Another technical result, manifested when using the claimed technical solution, is to simplify the design of the profile, to provide the possibility of using the fixation device in other known profiles.

The essence of the claimed technical solution lies in the fact that the device for fixing the canvas in the profile of the harpoon attachment of the suspended ceiling with an indent from the wall is made in the form of a profiled article with the possibility of installation in the cavity for placing the harpoon of the profile of the attachment of the suspended ceiling. The fixing device has first and second stop points. It differs in that the device is made of hard plastic with the possibility of installing the first and second abutment points between the protrusion of the profile harpoon stop and the profile web bypass edge, which forms a stop on the inner side of the harpoon placement cavity.

The above essence is a set of essential features of the claimed technical solution, ensuring the achievement of all the claimed technical results.

Due to the fact that the fastening profile of the stretch ceiling is extended, the implementation of the fixing device in the form of a profiled product also allows you to have extended contact with the profile and the web along the profile, which increases the reliability of holding the web in the profile, allows you to use a simple profile design or use the claimed device in other well-known profiles along their entire length.

Installation of the fixation device in the cavity for placing the harpoon of the stretch ceiling attachment profile, that is, in the place of the direct exit of the web from the profile, makes it possible to make the fixation device of a smaller linear size in the cross section, that is, to ensure its rigidity with a minimum amount of material, which increases the reliability of holding the web in the cavity ... Such an arrangement of the claimed device can be implemented in all profiles of the harpoon type of fastening a stretch ceiling due to the presence of a cavity for accommodating a harpoon in all such profiles. This does not lead to complication of the profile design. In addition, the specified location of the claimed device ensures that this device retains the function of hiding the harpoon and its soldering from the user's view of the mounted stretch ceiling.

In the claimed device there are two thrust points, the device is made with the possibility of installing these points between the protrusion of the stop of the profile harpoon and the edge of the profile web bypass, which forms an emphasis on the inner side of the cavity for placing the harpoon. Such a design uses structural elements to hold the claimed device, which are objectively inherent in most profiles of the harpoon fastening of a stretch ceiling indented from the wall. There is no need to make additional protrusions in the profile to hold the claimed device, as is done in RU 204903. In this case, the mentioned protrusion of the harpoon stop and the edge of the web bypass are located at a minimum distance from each other, which, as mentioned above, increases the reliability of holding the web.

The design of the fixing device made of hard plastic provides sufficient force for pressing the web against the edge of the profile web bypass. This allows the device to perform not only a decorative function, closing the cavity for placing the harpoon from prying eyes, but also to keep the canvas in the profile, complementing the harpoon in this purpose. The execution of the device from hard plastic also makes it possible to hold it between the protrusion of the profile harpoon stop and the profile web bypass edge, which forms a stop on the inner side of the harpoon placement cavity.

In special cases, it is permissible to carry out a technical solution as follows.

The first stop is preferably made in the form of a groove with the possibility of interaction with the protrusion of the stop of the profile harpoon. The first stop point can be made in the form of a rough or ribbed surface with the possibility of interacting with the protrusion of the profile harpoon stop. The second stop is desirably made in the form of a wedge with the ability to interact with the edge of the profile web bypass.

The fixing device is desirably provided with a surface made with the possibility of pressing the joint area of the harpoon and the stretch ceiling web against the outer wall of the profile. In this case, the specified surface is provided with a cutout directly for the soldering of the mentioned harpoon and the web.

Close to the first sludge of the second stop on the outer side, the fixing device is expediently provided with a dismantling tongue.

The author of the claimed technical solution made prototypes of this solution, the tests of which confirmed the achievement of all the specified technical results.

Brief description of the drawings.

The figure 1 shows a diagram of the arrangement of the fixing device; in fig. 2 - a fixing device according to a preferred embodiment; in fig. 3 - fixation device according to example 1; in fig. 4 - fixing device according to example 2; in fig. 5 - fixing device according to example 3; in fig. 6 - fixing device according to example 4; in fig. 7 is an example of installing a fixing device.

Embodiments of the technical solution.

The device for fixing (1) the web in the profile (2) of the harpoon fastening of the stretch ceiling with an indent from the wall is a profiled product made of hard plastic (Fig. 1).

The fixing device is intended for additional to the harpoon (3) holding the stretch ceiling canvas (4) in the profile while simultaneously hiding from prying eyes the area where the harpoon is located with the stretch ceiling canvas welded to it at the soldering point (5). It is preferable to use the fixation device in the loaded places of fastening the canvas of the stretch ceiling, as well as in places of good visibility of the inner region of the profile of the fastening of the canvas. Such places are the areas of the outer corners of the room, as well as any location of the profile not near the walls of the room (areas of decorative joints, transitions with a change in the type of canvas or level, adjoining to cabinets, sliding partitions, high doors, curtains, curtains and other similar objects in the room , including when using a profile in which a cavity for accommodating a harpoon and a cavity for accommodating, respectively, the upper wheels of the cabinet, partition or door, fasteners for curtains or curtains are combined).

In view of the fact that the inner area of the stretch ceiling fastening profile with an indent from the wall is visible at the outer corners of the premises at a distance of about 6 cm, it is advisable to make the fixing device in length not less than this distance.

In cases where the fastening profile does not pass against the wall of the room, it is advisable to install a fixing device along the length of this entire profile. In this case, it is possible to use a fixing device, the length of which corresponds to the length of the profile, or to use several fixing devices 2 or 2.5 m long, joining them in the profile with their ends.

For the manufacture of the fixation device, thermoplastic polymers, thermosetting plastics, composite polymers can be used. Reinforcement of the material is allowed during the manufacture of the fixing device. The fixing device is preferably made in one piece.

The fixation device has the first (10) and the second (11) thrust points (Fig. 2), with which it is installed between the protrusion (21) of the profile harpoon stop and the flange (22) of the profile web bypass, which forms an emphasis on the inner side of the cavity (23) placement of the harpoon (Fig. 1).

Due to the fact that the stop of the harpoon in the profiles of the harpoon fastening of the stretch ceiling with an indent from the wall in the known implementations has the form of a protrusion (21), the first stop (10) is preferably made in the form of a groove, into which this protrusion enters when installing the fixing device ( 21).

Due to the fact that the side (22) of the web bypass in the profiles of the harpoon fastening of the stretch ceiling with an indent from the wall in the overwhelming majority of the implementation is made round in cross-section and is placed protruding into the cavity (23) for placing the harpoon, this side forms with the surface of the outer wall ( 24) of the profile an angle that allows this area of the profile to be used as a stop for the fixing device. The second stop (11) in this case is preferably made in the form of a wedge, which, when the fixing device is installed, abuts against the rim (22) near the said corner.

The second stop (11) can also be made in the form of a groove, into which, when the fixing device is installed, part of the rim (22) enters.

The fixing device can have a surface (12) for additional pressing of the area of connection of the web and the harpoon to the outer wall (24) of the profile. Such pressing is relevant when, as a result of significant tension of the web in the installed stretch ceiling without using a fixation device, the harpoon (3) is deployed in the cavity (23) of its placement in the profile (clockwise in the absence of a fixation device (1) in Fig. 1). Such a turn, in turn, increases the force aimed at opening (unbending) the harpoon (3), which ultimately happens, especially if the end part of the harpoon is not rigid enough and itself also bends under the action of the pulling force of the web on the harpoon unbending at the top.

It is advisable to provide the surface (12) with a cutout (13) for the area of soldering (5) of the harpoon (3) with the blade (4). Since the specified adhesion forms a thickening of the material, the size of which is not regulated and can be arbitrary, this thickening is placed during the operation of the fixation device in the cutout (13). This allows the surface (12) to press the end of the harpoon (3) close to the outer wall (24) of the profile. In this case, the fixing device will be fully installed with the first stop point (10) in the protrusion (21) of the harpoon stop.

If there is a surface (12), the fixing device may contain a recess (14) on the opposite side to save material and create a visual effect.

The tongue (15) can be formed on the outside of the locking device near the first stop (10) to facilitate the dismantling of the locking device.

The fixing device can be manufactured by extrusion or coextrusion (with reinforcement), by casting, molding or 3D printing.

Examples of specific implementation.

Example 1. The first stop is made in the form of a rough or ribbed surface (101), allowing the fixation device to be installed with a different distance of the surface (12) of pressing the area of connection of the spear with the web from the outer wall (24) of the profile (Fig. 3). The second stop (11) is made in the form of a wedge.

Example 2. The first (10) and second (11) thrust points are made in the form of grooves (Fig. 4). The fixing device does not contain a surface for pressing the area of connection of the spear with the web against the outer wall of the profile (24).

Example 3. The first stop (10) is made in the form of a groove, the second stop (11) is made in the form of a wedge (Fig. 5). A tongue (16) to facilitate dismantling of the locking device is made on the outer side of the locking device near the second stop (11). The tongue (16) is made covering the side (22) on a part of its surface. The fixing device does not contain a surface for pressing the area of connection of the spear with the web against the outer wall of the profile (24).

Example 4. The fixing device is similar to example 3, but the dismantling tab (15) is also made at the first stop (10) (Fig. 6).

Example 5. For a double profile having two cavities (23) for accommodating a harpoon, it is advisable to use a double fixation device, which is a single-piece fixation device, the regions near the first stop points (10) of which are connected to each other by a bridge (17) (Fig. 7).

The implementation of the proposed technical solution is not limited to the above examples. For example, for the twin profile shown in FIG. 7, it is permissible to use a separate fixation device for each cavity (23) for placing the harpoon.

The order of use.

When using the fixation device by known methods, the profile (2) is mounted to the wall of the room, and the harpoon (3) with the edge of the web (4) fixed to it is placed in an interference fit in the cavity (23).

Then the fixing device (1) is installed between the protrusion (21) of the profile harpoon stop and the rim (22) of the profile web bypass. In this case, either first, the first stubborn place (10) is brought into contact with the protrusion (21), and then the second stubborn place (11) is snapped on the side (22), or the second stubborn place (11) is first placed on the side (22), and then the first stop (10) is latched onto the projection (21).

For reliable installation of the fixing device, an insert (6) (Fig. 7) can be placed between the wall (7) and the fixing device (1). The insert (6) can be elastic. The insert (6) can be made in one piece with the fixing device.

Dismantling of the fixing device is carried out either starting from the end of this device, or using dismantling tongues (15, 16). Industrial applicability.

The claimed technical solution is implemented using commercially available materials, can be manufactured in industry and will find wide application in the field of arranging stretch ceilings with harpoon fastening with a visible indent from the wall.
