The solution can be used for installation of an existing wall (after removing some of the top finish materials) and is particularly relevant for installing a flush mounted device in a wall that is being constructed and requires to be applied with finish materials, such as plaster. This is very common in the case of concrete wall construction, mortar construction or brick wall construction. The solution provided by the present disclosure allows to plan the thickness of the finish materials to be applied to the walls such that the end result of the mounted device is flushed with the finished wall.

For doing that, the present disclosure provides a cavity forming unit that is associated with a base unit that is installed in the wall during the early construction stage thereof, namely prior to application of finish materials thereon. The cavity forming unit is controllably positioned, by a depth calibration mechanism, at a desired position along a depth axis so as to determine the protrusion extent of the cavity forming unit from the surface of the unfinished wall. Then, finish materials can be applied around the cavity forming unit and after that the finish process is over, the cavity forming unit is removed,

DETAILED DESCRIPTION

The following figures are provided to exemplify embodiments and realization of the invention of the present disclosure.

The term "about" throughout the specification should be interpreted as a deviation of +20% of the nominal value. For example, if the value is about 10, thus it should be understood to be in the range of 8-12.

Reference is first made to Figs. 1A-1E, which are schematic illustration of different views of a non-limiting example of an embodiment of a cavity forming unit alone or in association with a base unit according one or more aspects of the present disclosure. The cavity forming unit 100 comprises a body 102 defined between a first face 103 and a second face 105 and its shape is defined by peripheral walls 104. The peripheral contour of the peripheral walls 104 are designed to allow to form a specific cavity dimension in the wall, after applying finishing materials thereto, that fits to a specific device to be installed in the wall, so it is flushed with the finished wall. For allowing to form the desired cavity, the body 102 of the cavity forming unit 100 is designed to fit through an opening 106 of a receiving space 108 of a wall mount base unit 110 (or in short base unit), which can be best seen in Figs. 1E. The base unit 110 is intended to be first installed in the unfinished wall, typically a wall made of concrete, such that it is flushed or almost flushed with the unfinished wall or at least the opening of the receiving space. The cavity forming unit 100 further comprises a first part of a depth calibration mechanism 112A that is configured to associate with a second part of a depth calibration mechanism 112B formed in the base unit 110. The first part of the depth calibration mechanism 112A is constituted by through-holes 114 that are formed in four portions of the body 102 and are configured to receive screws 115 and allow them to be screwed to respective threads 116 in the base unit 110, in particular in a distal part from the opening or a bottom 118 of the base unit 110. The through-holes 114 are extending between the first face 103 and the second face 105 such that they are accessible from the first face 103. It should be noted that when referring to screws it may include also nuts and other parts that are used by the skill in the art for a screwing process. The through- holes 114 that are formed in the body 102 are coverable by removable covers 117, e.g. plugs, that are intended to be placed over the opening of through-holes 114 on the first face 103 when finishing materials are applied to the wall and are intended to be removed

Tautz & Schuhmacher IP CDS1102P11LU June 28, 2022 LU502392 9/16 when finish materials are applied to the wall, thereby protecting the through holes from being clogged by finish materials. After fitting the cavity forming unit 100 into the receiving space 108, the screws 115 are received in the respective threads 116 and by adjusting the screwing positions of the screws, the extent of the protrusion L of the first face 103 from the opening 106, or more specifically from the plane P defined by the opening, is adjusted. In other words, by utilizing the depth calibration mechanism, the depth position of the body within the receiving space of the base unit is calibrated. The extent of the protrusion L is defined according to the expected thickness of the finishing materials that are to be applied to the wall around the cavity forming unit 100 and therefore dictates the dimension of the cavity to be formed, after the extraction of the cavity forming unit 100 following the finish of the wall.

The peripheral walls 104 are covered or wrapped by a separation material 118 that is intended to separate the peripheral walls 104 from the finish materials that are applied to the wall to allow easy extraction of the cavity forming unit 100 at the end of the finishing process. The separation material can be a synthetic polymer, and in some embodiments, it can be a shrink wrap material, such as PVC, PE or POF. The separation material 118 is characterized to allow easy dissociation from the peripheral walls, e.g. by peeling off from the peripheral walls during the extraction process. In some embodiments, the entire body is wrapped by the separation material, protecting it during shipping, transportation, or the installation process. In such embodiment, the access to the through- holes, from the first and the second faces, are to be made by puncturing the separation material in the specific places of the through-holes.

An extraction portion 120 is formed at the body 102, e.g. in a central portion of the body 102, and is accessible from the first face 103, which is intended to face at the opposite direction of the receiving space 108. In this specific embodiment, the extraction portion 120 is in the form of a through-hole extending between the first and second faces 103 and 105, and is designed to allow gripping of the body 102 for extracting it after the finishing process. It is to be noted that if the body is entirely wrapped with the separation material, the portion of the separation material that covers the extraction portion is required to be punctured prior to the extraction process.

In the figures throughout the application, like elements of different figures were given similar reference numerals shifted by the number of hundreds corresponding to the

Tautz & Schuhmacher IP CDS1102P11LU June 28, 2022 LU502392 10/16 number of the respective figure. For example, element 210 in Figs. 2A-2C serves the same function as element 110 in Figs. 1A-1E.

Figs. 2A-2C are schematic illustrations of different views of a non-limiting example of an embodiment of the wall mount base unit, with which the cavity forming unit is intended to associate therewith. The base unit 210 comprises a base body 230 defining a receiving space 208 for receiving the cavity forming unit therein. The receiving space has about the same dimensions as of the cavity forming unit (the cavity forming unit is slightly smaller than the receiving space so as to allow its insertion thereto). The base body 230 comprises a bottom surface 232 that is formed with an aperture 234 for receiving electric box or other electronic components 235 to allow, after the installation process of the mounted device, to electrify the mounted device. Furthermore, the bottom surface 232 is formed with the second part of the depth calibration mechanism 212B, which is constituted by threads 216 intended for receiving the screws from the cavity forming unit to allow controlling the depth position of the cavity forming unit within the cavity, namely, the protrusion extent of the first face of the cavity forming unit from the plane P defined by the opening 206 of the receiving space 208.

The base unit 210 further comprises extensions 236 outwardly extending from the base body 230, namely extending away from the receiving space 208. The extensions are intended to be flat on the peripheral portion of the cavity of the wall, in which the base unit 210 is installed in to firmly hold it in position.

Reference is now being made to Figs. 3A-3G, which are schematic illustrations showing different views of the steps of the process of the installation of a flush-mount device in a wall.

Figs. 3A-3B show the basic association between the cavity forming unit 300, the depth calibration mechanism 312 and the base unit 310, wherein the enlarged portion of

Fig. 3A shows the portion of the peripheral walls 304, which is applied, covered, or wrapped the separation material 318.

Figs. 3C-3D show the insertion of the base unit 310 to an intended portion of the wall WL and the cavity forming unit 300 is associated thereto via the depth calibration mechanism 312 to allow calibrating the depth penetration of the cavity forming unit 300 into the receiving space 308 so as to position the first face 303 of the cavity forming unit 300 at the desired protrusion extent from the opening 306 of the receiving space 308.

Tautz & Schuhmacher IP CDS1102P11LU June 28, 2022 LU502392 11/16

Furthermore, in Fig. 3C, it can be seen that the base unit 310 is coupled with an electric box 335 that guides electronics therethrough and is configured to electrify the electronic mounted device.

After the depth calibration process, the finish materials FM are applied to the wall and the cavity CAV is formed. Then, the cavity forming unit 300 is dissociated from the base unit 310 and is extracted, together with at least a part of the depth calibration mechanism 312, as can be seen in Fig. 3E.

Reference is now being made to Figs. 3F-3G, which show that the device adaptor platform 350 is associated with at least a part of a depth calibration mechanism 312, which can be the same as the one of the cavity forming unit 300 or different, for allowing to control the depth penetration position of the device adaptor platform 350 within the formed cavity CAV, namely the distance of the front face of the device adaptor platform 350 from the opening of the formed cavity CAV. The mounted device MD is then coupled to the device adaptor platform 350 to be flush mounted in the wall.
