    [0001] TECHNICAL FIELD The present invention relates to the field of accessories used before applying liquids or other fluids on surfaces. It relates more particularly to a kit and a method of masking a surface to be treated. The present invention finds a particularly advantageous application, although in no way limiting, in kits and methods for masking aircraft windows before painting their fuselages. STATE OF THE ART At present, various devices and methods are known for masking one or more delimited parts of a surface so as to apply to said private surface of said delimited portions a treatment which may as well be necessary for its protection as for its aestheticism. Thus, such devices and methods are respectively used and implemented, for example, to cover openings before application of protective layers against rusting of metal surfaces such as car bodies, boat hulls, fuselages. aircraft, cockpit of construction machinery or other. It may also be devices and methods for covering delimited portions of a surface before decoration of the latter by applying one or more layers of paint around said delimited portions. Therefore, when said delimited portions are an integral part of the surface as produced, the masking devices have shapes substantially identical to those of said parts delimited so that they are intended to be superimposed on them. These devices are particularly used on the outer surface of the fuselage of an aircraft, said surface being intended to be painted by means of a spraying of a coating. This spraying occurs while said fuselage is already equipped with portholes (or possibly other accessories) which are here said delimited parts, and that it is therefore necessary to protect by masks of suitable shapes to preserve them from any projection of paint . Conventionally, an aircraft window has a glass window 3036045 2 embedded in a metal support, said metal support being riveted to the fuselage of the aircraft so that only a flange peripheral to said glass window is visible from the outside the aircraft. In order to cover a window, those skilled in the art use a device comprising a mask of shape and area identical respectively to the shape and the area of the glass window of a window, and intended to be superimposed on said window. glass window by means of an adhesive tape at the periphery of said mask. In addition to this mask, and in order to minimize the risk of splashing paint, a person skilled in the art applies a first masking tape 10 at a joint positioned between said glass window and said metal support, such as a piece of adhesive tape. In order to optimize the uniformity of the paint deposit around the window, a first layer is generally applied once the superimposed mask to said porthole. Once this layer dries, the skilled person proceeds to the application of a second masking tape on said collar, following its contours at best, and this in order to deposit a new layer of paint. Such a procedure is disadvantageous in that the second masking band, which is rectangular in shape, is intended to protect the flange which generally has rounded areas. Thus, the adhesion of the masking tape at said rounded areas is not perfect, which prevents a well-defined application of the paint at the contours of the flange, thus adversely affecting the aesthetics of the aircraft. In addition, because of this non-perfect adhesion of the masking tape to the flange, paint 25 is likely to migrate to the glass window of the window thus increasing the risk of soiling. PRESENTATION OF THE INVENTION The object of the present invention is to remedy all or some of the drawbacks of the prior art, in particular those set out above, by proposing a solution that makes it possible to have masking kits for an area a surface to be treated adapted to the contours of said zone so as to optimize the uniformization of the deposition of the treatment and to avoid any migration of treatment to said zone during its deposition. For this purpose, and according to a first aspect, the invention relates to a kit for masking an area of a surface intended to be treated, in particular the external surface of an aircraft fuselage, said zone comprising an internal part. and a peripheral outer portion separated by an intermediate portion. In addition, the masking kit comprises a first mask: of shape and of area substantially identical respectively to the shape and the area of said internal part, and intended to be superimposed on said inner part, comprising a first face coated with an adhesive substance and covered with an at least partially removable protective sheet, and a second mask: - of shape and area identical respectively to the shape and the area of the outer peripheral portion added with the intermediate portion, and intended to be superimposed on said peripheral outer portion and on said intermediate portion, comprising a first face coated with an adhesive substance intended to adhere to said peripheral outer portion as well as to said intermediate portion; , said first face being covered with an at least partially removable protective sheet, and a second face covered with an application sheet has movible and adapted to facilitate the transfer of the second mask to the zone. In particular embodiments, the masking kit may further include one or more of the following features, taken alone or in any technically possible combination. In a particular embodiment, the protective sheet of the first mask comprises a peripheral pre-cut dividing said protective sheet into a peripheral strip and a complementary central portion, said peripheral strip comprising at least one radial precut. In a particular embodiment, the first mask comprises withdrawal means intended to allow said first mask to be detached from said inner portion, said removal means comprising a V-shaped half-flesh cutout arranged in the middle of the first part. face of the first mask, and a withdrawal tab covered with adhesive substance and covering said cut while retaining an end left free. In a particular embodiment, the second mask comprises peripheral withdrawal means intended to allow the delamination, by traction on said withdrawal means, of said second mask of said peripheral outer portion and said intermediate portion.
    [0002] In a particular embodiment, said removal means comprise a withdrawal tab arranged in one piece on the contour of the second mask. In a particular embodiment, the second mask comprises dissociation means intended to facilitate the separation, by traction on said dissociation means, of said application sheet of the second mask. In a particular embodiment, said dissociation means comprise a separating tab left free arranged in one piece on the contour of said application sheet.
    [0003] In a particular embodiment, said second mask comprises positioning means intended to allow precise superposition of the second mask on the peripheral outer portion and the intermediate portion. In a particular embodiment, said positioning means comprise at least one through hole arranged so as to show the delimitation between the intermediate portion and the inner portion, and contour having a portion, said positioning portion, remote from the contour the second mask a distance equal to the width of said peripheral outer portion.

    [0006] In these figures, identical references from one figure to another designate identical or similar elements. For the sake of clarity, the elements shown are not to scale unless otherwise stated. DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION The present invention finds its place in the field of surface treatment industrial operations, said treatment having various protective or decorative functions (anti-rust, colored paint, varnish, etc.), or even cleaning (pickling, sanding, degreasing, etc.).
    [0007] Figure 1 shows schematically an example of a zone (10) of a surface to be treated. The invention relates, in a first aspect, a masking kit of said zone (10). Therefore, the area to be masked is a surface included in said surface to be treated, and has a contour delimiting it.
    [0008] In the remainder of the description, the concept of "surface" is taken in the most general sense possible. Also, the term "surface" includes both flat or left surfaces, as are generally fuselages and bodywork, as well as irregular surfaces, such as for example the elements of joints between a body and a window.
    [0009] In the present exemplary embodiment, the surface to be treated is metallic. Nothing, however, excludes that said surface to be treated is made of other materials, such as synthetic plastics, wood, glass, etc. The zone (10) to be masked may also be of any kind, provided that its surface characteristics allow all or part of the masking kit to adhere thereto by means described below. The area to be masked has an inner portion (11) and an outer peripheral portion (13) separated by an intermediate portion (12). Thus, said peripheral outer portion (13) and said zone (10) have an outline in common. The remainder of the description is directed more specifically, but in a non-limiting manner, to a mask kit for a window of an aircraft fuselage. That is, the area (10) to be masked corresponds to the total area of said porthole, the latter having a glass window embedded in a metal support, said metal support being riveted to the fuselage of the aircraft so that that only a collar peripheral to said glass window is visible from outside the aircraft. In addition, said porthole has a seal positioned between said glass window and said metal support. Therefore, and for the rest of the description, said inner (11), external peripheral (13) and intermediate (12) respectively refer to said glass window, said flange and said seal. It should be noted that an aircraft conventionally comprises a plurality of portholes with identical dimensions, so that the size of the zones (10) to be masked is also identical. As a result, the masking kits, which are respectively disposable for each porthole, are advantageously produced in series according to said size of the areas (10) to be masked. Nothing, however, excludes, according to other examples not detailed here, 25 having zones (10) to be masked of different sizes, and therefore masking kits of different sizes, for a single aircraft. The masking kit includes a first mask (20) to be superimposed on said inner portion (11), and a second mask (30) to be superimposed on said outer peripheral portion (13) and on the other. intermediate part (12). FIG. 2a and FIG. 2b show schematically an exemplary embodiment of the first mask (20) of the masking kit, and correspond to two views respectively according to a first face (21) and a second face 3036045 8 (22) of said first mask ( 20). FIG. 2b also illustrates the zone (10) to be masked, and comprises dashed elements belonging to said first face (21) and masked by said second face (22). Said first mask (20) is of flexible design, and is made for example by molding plastic materials such as PVC (acronym for "Poly Vynil Chlorid"). Said first mask (20) of the masking kit is of identical shape and area respectively to the shape and the area of said inner part (11). Such a configuration of the first mask (20) is advantageously adapted so that it is intended to be superimposed on said inner part (11) so that the contours of said first mask (20) and said inner part (11) are confused. In the nonlimiting example illustrated in FIG. 2a, the first mask (20) of the masking kit is of substantially rectangular shape with rounded corners. In an alternative embodiment, said first mask (20) is of identical shape to the shape of said inner portion (11), and of area substantially smaller than the area of said inner portion (11), the ratio between area of the first mask (20) and the area of the inner portion (11) being greater than 20 0.9. Such a configuration is adapted to a partial covering of said inner portion (11) by said first mask (20), so as to leave free a residual space covered by the skilled person by means of a masking tape as described later. Such an embodiment is advantageously adapted to the use of a first mask (20) belonging to a masking kit manufactured for another zone to be masked. The first face (21) of the first mask (20) is coated with an adhesive substance, that is to say a synthetic material for adhering two surfaces without wetting. Said adhesive substance is characterized in particular by a tackiness chosen in a range of 30 values so as to allow the first mask (20) to remain in place on said inner portion (11) during the treatment of the surface, to remain attached to the first mask (20) when it is removed from said inner portion (11), and not to leave a trace on said inner portion (11). The properties of the adhesive substances are well known to those skilled in the art who will be able to choose, especially in the catalog of products offered by the specialized manufacturers, a range of adhesives for compositions adapted to the characteristics of the masking kit used.
    [0010] In the present exemplary embodiment, the tackiness of the adhesive substance of the first mask is between 2.5 N.cm-1 and 4.5 N.cm-1. However, there is nothing to preclude that, according to other examples not detailed herein, the tackiness of the adhesive substance of the first mask (20) is included in other ranges of values.
    [0011] The first mask (20) also comprises a protective sheet (23) covering its first face (21) and adapted to allow storage and better grip of said first mask (20). In the nonlimiting example illustrated in FIG. 2a, the protective sheet (23) of the first face of the first mask is a sheet of silicone paper, such as kraft paper, of dimensions identical to the dimensions of the first face ( 21) of the first mask (20). Said protection sheet (23) is superimposed on the first face (21) of the first mask (20) so that their respective contours are merged. Nothing, however, excludes, according to other examples not detailed herein, having different material and size characteristics for said protective sheet (23). Furthermore, said protective sheet (23) of the first mask (20) is at least partially removable so that the first mask (20) adheres to said inner portion (11) of the zone (10) to be masked in whole or in part from his first face (21).
    [0012] In a preferred embodiment, and as shown in FIG. 2a, the protective sheet (23) of the first mask (21) comprises a peripheral precut (24) along a closed line parallel to the contour of said first mask (20). ). Said peripheral precut (24) divides the protective sheet (and therefore also the first face (21) of the first mask (20)) into two distinct zones: - a peripheral band (25) of width preferably comprised in the interval [ 1 cm, 2 cm], - a complementary central part (26).
    [0013] Such a configuration makes it possible to separately separate the peripheral strip (25) and the complementary central portion (26) from the protective sheet (23). In addition, said peripheral strip comprises at least one radial precut (27) adapted to facilitate the dissociation of said protective sheet (23) from said first face (21). In a more particular embodiment, said peripheral strip (25) of the protective sheet (23) comprises two radial pre-cuts so as to be divided into two segments. For example, said two segments are configured so that the ratio of their respective lengths is 2.
    [0014] However, there is nothing to preclude that, in other examples not detailed here, said peripheral band (25) is divisible into more than two segments whose ratio of lengths differs from 2. Alternatively, in a particular embodiment, the sheet The protector (23) of the first mask (20) is configured to be completely removable in one piece and in a single gesture by those skilled in the art. In a preferred embodiment, and as illustrated in FIG. 2b, the first mask (20) also comprises withdrawal means intended to allow the separation, by traction on said withdrawal means, of said first mask (20). of said inner portion (11) when superimposed on it. Said removal means comprise for example a V-shaped half-cut (28) arranged in the middle of the first face (21) of the first mask (20), and a withdrawal tab (29) covered with adhesive substance. and covering said cutout (28) while maintaining an end left free.
    [0015] By being left free, it is meant here that said end is not covered with adhesive substance. Such a configuration of the withdrawal means is advantageous because it allows a one-time removal of the first mask (20) by pulling on said end of the withdrawal tab (29), when it adheres to the inner part (11). .
    [0016] FIG. 3a and FIG. 3b schematically represent an example embodiment of the second mask (30) of the masking kit, and correspond to two views respectively according to a first face (31) and a second face (32) of said second mask (30). ).
    [0017] Said second mask (30) is of shape and area identical respectively to the shape and the area of the peripheral outer portion (13) added with the intermediate portion (12). Such a configuration of the second mask (30) is adapted so that the latter is intended to be superimposed on said peripheral outer portion (13) as well as on said intermediate portion (12), so that the contours respectively of said second mask (30) and said outer peripheral portion (13) are merged. In the nonlimiting example illustrated in FIG. 3a, the second mask (30) of the masking kit is of substantially rectangular annular shape with rounded corners. The first face (31) of the second mask (30) is coated with an adhesive substance having characteristics identical to those of the adhesive substance coating the first face (21) of the first mask (20), said first face (31) of the second mask (30) being adapted to adhere to said peripheral outer portion (13) as well as to said intermediate portion (12) by conforming their respective contours. For this purpose, the width of the second mask (30) is configured to be equal to the width of said peripheral outer portion (13) plus the width of said intermediate portion (12). The second mask (30) is shown in dotted lines in FIGS. 3a and 3b because, when it is not yet superimposed on said peripheral outer portion, its first (31) and second (32) faces are masked respectively by a protective sheet and an application sheet described below. The second mask (30) also comprises a protective sheet (33) covering its first face (31) and adapted to allow storage and a better grip of said second mask (30). In the nonlimiting example illustrated in FIG. 3a, the protective sheet (33) of the first face (31) of the second mask (30) is a sheet of silicone paper, such as kraft paper, of dimensions identical to the dimensions of the first face (31) of the second mask (30). In this way, said protective sheet (33) is superimposed on the first face (31) of the second mask (30) so that their respective contours are merged. Nothing, however, excludes, according to other examples not detailed here, 3036045 12 having different material characteristics and dimensions for said protective sheet (33). Furthermore, said protective sheet (33) of the second mask (30) is at least partially removable so that the second mask (30) 5 adheres to said peripheral outer portion (13) as well as to the intermediate portion (12) according to all or part of the surface of its first face (31). In a preferred embodiment, and as shown in FIG. 3a, the protective sheet (33) of the second mask (30) has a pre-cut (34) along a width of the second mask (30) and is positioned by example and not limited to two-thirds of its length. Said precut (34) divides the protective sheet (33) (and consecutively also the first face (31) of the second mask (30)) into two distinct zones, an upper zone (35) and a lower zone (36). Such a configuration makes it possible to separately separate the high (35) and low (36) areas of the protection sheet (33). Nothing, however, excludes, according to other examples not detailed here, having one or more pre-cuts of the protective sheet (33) of the second mask (30) dividing it into other areas of different shapes and sizes. Alternatively, in a particular embodiment, the protective sheet (33) of the second mask (30) is configured to be completely removable in a single piece and in a single gesture on the part of the skilled person . In addition, the second mask (30) comprises an application sheet (40) covering its second face (32) and adapted to facilitate the transfer of the second mask (30) to the zone (10). In addition, said application sheet (40) is adapted to allow a better grip of the second mask (30) during its superposition to the outer peripheral portion (13) and the intermediate portion (12). More specifically, said application sheet (40) facilitates the handling of the second mask (30) when its protective sheet (33) is removed, giving it increased rigidity with respect to that of the second mask (30) taken alone . In the nonlimiting example illustrated in FIG. 3b, the application sheet (40) of the second mask (30) is a sheet of silicone paper, 3036045 13 such as kraft paper, of dimensions identical to the dimensions of the second face. (32) of the second mask (30). In this way, said application sheet (40) is superimposed on the second face (32) of the second mask (30) so that their respective contours are merged. Nothing, however, excludes, according to other examples not detailed here, having different material and size characteristics for said application sheet (40). Furthermore, said application sheet (40) of the second mask (30) is removable from the second face (32) of the second mask (30) in one piece. FIG. 4a and FIG. 4b show schematically a preferred embodiment of the second mask (30), and correspond to two views respectively of the first face (31) and the second face (32) of the second mask (30) in which this the latter comprise positioning means intended to allow a precise superposition of the second mask (30) on the outer peripheral part (13) and the intermediate part (12). FIG. 4b also illustrates in dotted lines, because masked by the application sheet (40), the intermediate part (12). For example, said positioning means comprise at least one through hole (50) arranged so as to reveal the delimitation between the intermediate portion (12) and the inner portion (11) when the second mask (30) provided with its sheet application (40) is superimposed on the peripheral outer portion (13). The contour of said at least one through-hole (50) includes a portion, said positioning portion (51), remote from the contour of the second mask (30) by a distance equal to the width of said peripheral outer portion (13). Such a configuration is advantageous because intended to allow a precise superposition of said positioning portion (51) of said at least one through hole (50) with the delimitation between the outer peripheral portion (13) and the intermediate portion (12).
    [0018] In the nonlimiting example illustrated in FIG. 4a, said positioning means comprise two through-holes (50). Said two through holes (50) are arranged in said upper zone (35) of the protective sheet (33) facing each other in the width of the second mask 3036045 14 (30). Nothing, however, excludes, according to other examples not detailed here, having a number and a different arrangement of the through holes (50). As illustrated in FIG. 4a, the second mask (30) also preferably comprises peripheral withdrawal means intended to allow the traction surface of said second mask (30) of said peripheral outer portion to be detached by pulling on said withdrawal means ( 13) and said intermediate portion (12) when superimposed on them. Said removal means comprise for example a withdrawal tab (37) arranged in one piece on the contour of the second mask (30), at one of its corners.
    [0019] In addition, the shape and size of said withdrawal tab (37) are adapted to allow one-time removal of the second mask (30) when that adheres to the peripheral outer portion (13). Furthermore, and as illustrated in FIG. 4a, the application sheet (40) of the second mask (30) comprises dissociation means intended to facilitate the separation, by traction on said dissociation means, of said sheet applying (40) the second mask (30). Said dissociation means comprise for example a dissociation tab (41) left free arranged in one piece on the contour of said application sheet (40), at one of its corners. By being left free, it is meant that said dissociation tab (41) is not coated with adhesive substance so as not to adhere to the surface to be treated. The invention also relates, in a second aspect, to a method of masking an area (10) of a surface to be treated by means of a masking kit as described above. FIG. 5 represents a flowchart of an exemplary implementation of said masking method. The masking process comprises a step 100 of removing all or part of the peripheral band (25) of the protective sheet (23) of the first mask (20). A preferred embodiment of this step 100 consists in slightly folding the first mask (20) at the level of said peripheral precut (24) separating said peripheral band (25) from said complementary central portion (26) of the first mask. (20), so as to dissociate them. Then, the first mask (20) is also slightly folded at the level of said at least one radial precut (27) so as to facilitate the gripping of said peripheral strip (25) which is removed while leaving said complementary central portion (26) ) in place. In a particular embodiment of step 100, when the peripheral strip (25) of the protective sheet (23) of the first mask (20) comprises two radial cuts (27), only one of said two segments between two radial cuts are removed from the first face (21) of the first mask (20). The masking process then comprises a step 110 of superposition of the first mask (20), according to its first face (21), to the inner part (11) of the zone to be masked. Said superposition is in particular carried out according to the peripheral strip (25) of the first face (21) of the first mask (20), so that the contours of said first mask (20) and said inner portion (11) are merged. Optionally, when the first mask (20) is of area slightly smaller than the area of said inner portion (11), said superposition is made so that the first mask (20) is centered on said inner portion (11) , thus leaving a residual space between the contour of said first mask (20) and the contour of said inner portion (11). Thus, said first mask (20) does not adhere over its entire surface to said inner portion (11) but only according to the surface of said peripheral strip (25) of its first face (21). Such a procedure is advantageous because, all processing operations performed, the removal of said first mask (20) of said inner portion (11) is facilitated. In a particular embodiment of step 110, the superposition of the first mask (20) to the inner part (11) of the zone (10) to be masked is performed according to said segment removed from the peripheral band (25). .
    [0020] Thus, the first mask (20) is placed in front of said inner portion (11) and adheres thereto in a first time only according to said removed segment. The remainder of the peripheral band (25) of the first face (21) of the first mask (20) is then removed to adhere the entire first mask (20) to said inner portion (11) along any said peripheral band (25). Such an implementation of the masking method is advantageous because it makes it easier to correct the placement of the first mask (20) insofar as the latter (20) adheres to said inner part (11) in a first step, according to a part reduced of said peripheral band (25). The masking process then comprises a step 120 for protecting the intermediate portion (12) of the zone (10) to be masked by means of a masking tape. Said masking tape is a piece of tape, of a type known per se, impervious to the treatment applied on the surface, and available to those skilled in the art. It adheres to said intermediate portion (12) by manual application following the boundary between said intermediate portion (12) and said peripheral outer portion (13). Optionally, when the first mask (20) is of area less than the area of said inner portion (11), said masking tape is positioned to also protect said residual space between the contour of said first mask (20). ) and the contour of said inner portion (11). The masking process then comprises a step 130 of removing all or part of the protective sheet (33) of the second mask (30). One particular embodiment of this step 130 consists in dissociating the protective sheet (33) from the second mask (30) by pinching the contour of said second mask (30). Said protective sheet (33) of the second mask (30) is removed in a single piece and in a single gesture from the skilled person. In a preferred embodiment of step 130, when said protective sheet (33) has a precut (34) along a width of the second mask (30) and dividing the protective sheet (33) into a zone high (35) and a low zone (36), only said high zone (35) is removed from the first face (31) of the second mask (30) at first. The masking process then comprises a step 140 of superposition of the second mask (30), according to its first face (31), to the peripheral outer portion (13) and to the intermediate portion (12). In a particular embodiment of step 140, the superposition of the second mask (30) to the peripheral outer portion (13) 3036045 17 as well as to the intermediate portion (12) is carried out according to said high zone (35). ) of the first face (31) of the second mask (30), which advantageously facilitates the positioning of the second mask (30). The lower region (36) of the protective sheet (33) of the second mask (30) is then removed to adhere the entire first face (31) of the second mask (30). In a preferred embodiment of step 140, the superposition of the second mask (30) to the zone (10) to be masked is performed according to said upper zone (35) of the first face (31) of the second mask ( 30) 10 by first adjusting the superposition of the positioning means. For example, when the second mask comprises positioning means such as for example at least one through hole (50), said positioning portion (51) of said at least one through hole (50) is superimposed on the delimitation between said portion external peripheral (13) and said intermediate portion (12) of the zone (10) to be masked. Such an implementation of the masking method is advantageous, said at least one through-hole (50) and its positioning portion (51) thus constituting a local adjustment mark allowing the person skilled in the art to superimpose the second mask. (30) to the outer peripheral portion (13) and the intermediate portion (12) using immediate corrective actions. In addition, it is advantageous for one skilled in the art to adjust the second mask (30) during step 140 by holding the mask at least at its dissociation means, such as the third one. tongue (41) described above. In this way, the risk of soiling of the first face (31) of the second mask (30) are reduced. It should be noted that this step 140 can be implemented either directly after superposition of the first mask (20) on the inner part (12), or after the person skilled in the art has made the application of a first layer. treatment on the surface to be treated. In the latter case, it is necessary to wait until the treated surface is dry before the effective implementation of step 140. Such a procedure is advantageous insofar as the application of several layers of treatment 3036045 18 promotes the standardization of the latter. The masking process then comprises a step 150 for removing the application sheet (40) from the second mask (30). A particular embodiment of this step 150 consists in dissociating the application sheet (40) from the second mask (30) by scraping the contour of said second mask (30). Said application sheet (40) of the second mask (30) is removed in a single piece and in a single gesture from the skilled person. In a preferred embodiment, when the second mask comprises dissociation means, such as the third tongue (41) described above, those skilled in the art initiate removal of the application sheet (40). by pulling on said third tongue. At the end of the implementation of the masking process, a treatment is applied to the surface to be treated. Then, the masking set 15 as well as said masking band are removed manually. Preferably, when the second mask (30) is equipped with withdrawal means, such as for example a second tongue (37), a person skilled in the art withdraws said second mask (30) by pulling on said second tongue (37). .
    [0021] More generally, it should be noted that the embodiments and implementations considered above have been described by way of non-limiting examples, and that other variants are therefore possible. In particular, the invention has been described by considering a kit for masking an area of an outer surface of an aircraft fuselage. Nothing, according to other examples, excludes having a masking kit for an area of a surface of a boat, of a motor vehicle, or else of industrial or public works equipment. .
