GENERAL DESCRIPTION

The present disclosure provides a solution for installing a flush mounted device in a wall. 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 flush with the finished wall. In some utilizations of the solution of the present disclosure, it facilitates to form the wall itself and the finish materials such that the end result of the mounted device is flush with the finished wall Therefore, the solution of the present disclosure is a new tool, provides a different solution that facilitates forming the wall, together with the finishing material, in a manner that the electric device installed in the wall is flush with the finished wall. This installation tool allows installation that requires electrical back boxes (line voltage installation) and installations without (low voltage electrical devices).

For doing that, the present disclosure provides a cavity forming unit that is associated with a base unit that is installed in the wall or foundations for constructing the wall during the early construction stage thereof, namely prior to application of finish materials thereon or even prior to the application of concrete that forms the wall. 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. The depth axis is defined normal to the plane formed by the 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, leaving a cavity in the desired dimensions that fits to receive device adapter components and the flush mounted device such that it is flush mounted in the wall.

Thus, a first aspect of the present disclosure provides a cavity forming unit for use in a flush-mount installation. It is to be understood that the cavity forming unit is assisting in forming the desired cavity in the wall such that the finish materials that are applied to a wall around the cavity forming unit are forming the cavity. The cavity forming unit comprising a body defined by peripheral walls extending between a first, cavity-facing, face and a second, opposite face. The peripheral walls defining a shape suitable to be fitted into a receiving space of a wall mount base unit that is being mounted on the wall or at a position where the wall is planned to be formed. The fitting can be tightly fitting. Namely, the peripheral contour of the body is about the same contour of the peripheral walls of the cavity such that it is allowed to fit thereinto. The wall mount base unit is configured to be installed within the wall and be associated or coupled with adapter components of a mounted device such as an electronic device (e.g. a touch screen, a switch, or any smart-home device), that in turn are attached to the electronic device to be mounted flush with the finished wall. Therefore, the wall mount base unit has a receiving space that is dimensioned to be fitted with a specific adapter component of an electronic device or can have adjustable cavity to allow to be fitted with a various adapter components of electronic devices in various dimensions. The wall mount base unit may also be configured to allow electrification of the electronic device, e.g. by having an aperture in the base of the receiving space for receiving an electric box or passing electric wires therethrough. The cavity forming unit further comprises a separation film, sheet or layer that is either applied to or covers at least a portion of the peripheral walls to separate the peripheral walls from the plaster, thereby allowing the extraction of the cavity forming unit after the application of the plaster. The separation film, sheet or layer is separable from the cavity forming unit upon manipulation thereon, e.g. by rupturing a portion of it and application of a pulling force thereon. If the separation film or layer covers at least a portion of the peripheral walls, it is required to be peeled or dissociated relatively easily from the cavity forming unit. The separation film or layer is applied to or covers a portion of the peripheral walls, so as to avoid direct contact between the body, and in particular the peripheral walls, and the plaster applied around the cavity forming unit. Furthermore, the separation film or layer is applied to or covers a portion of the peripheral walls in a manner that allows it to be separated from the cavity forming unit during the cavity forming process. For example, the separation film or layer is selected to minimally adhere to the plaster and to be peeled off the peripheral walls during extraction of the cavity forming unit.

The cavity forming unit further comprises a gripping portion accessible from the first face for allowing gripping of the cavity forming unit to extract it from the receiving space. The gripping portion allows to grip the cavity forming unit, by hand or with a designated tool and pull it from the cavity after the preparation of the installation process is over. The cavity forming unit comprises at least a part of or is configured to associate with a depth calibration mechanism that is allowing to control the position of the body within the receiving space such that the first face is at a desired protrusion extent from an opening of the receiving space of the wall mount base unit. Namely, the protrusion extent from the plane defined by the opening of the receiving space, which defines the cavity dimension to be formed by the finishing materials that will be applied to the wall. This is performed prior to the performance of finish to the wall, e.g. application of plaster and/or cladding material that results in the planned thickness of the finish of the wall that determines the extent of protrusion.

The cavity forming unit further comprises an anchoring mechanism for anchoring the body at the desired position within the receiving space. Namely, the anchoring mechanism is configured for association with a respective part of in the wall mount or specifically in the receiving space to result in an anchoring association between the body and the wall mount base, namely restraining the body in position within the receiving space. The anchoring can be triggered by a specific manipulation once the body is at the desired position, i.e. at a desired protrusion extent from an opening of the receiving space of the wall mount base unit. Another alternative can be that the anchoring occurs simultaneous with the calibration process by the calibration mechanism.

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 flush 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 unif), which can be best seen in Figs. IE. The base unit 110 is intended to be first installed in the unfinished wall, typically a wall made of concrete, such that it is flush or almost flush 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, serving also as an anchoring mechanism 113, 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 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 the position along a depth axis DA defined normal to the plane P defined by the opening or the wall, is adjusted and fixed in position. Therefore, in this non-limiting example, the screws 115 constitute both the calibration mechanism and the anchoring mechanism 113. 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 film 118, separable from the peripheral walls 104 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 such that the finishing materials, e.g. plaster, adhere to the separation film 118 and not the peripheral walls 104, and when the separation film 118 is separated from the peripheral walls 104, the peripheral walls are not adhered to the walls and the extraction of the cavity forming unit 100 is allowed. The separation film can be a synthetic polymer, and in some embodiments, it can be a shrink wrap material, such as PVC, PE or POF. The separation film 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 film, 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 filmin the specific places of the through-holes.

A gripping 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 gripping 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 film, the portion of the separation film that covers the gripping 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 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 film 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. 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.
