A PROCESS FOR MARKING A POSITION, AND AN ARRANGEMENT FOR CARRYING OUT THE PROCESS

Abstract: A process for marking a position, and an arrangement which can be used for this process. The invention makes it possible to fix a position quickly and exactly when marking, particularly in locations which are not readily accessible. After a marking part has been established on a marker (8) which has two parts (4A, 1B) with differing degrees of adhesion, the said marker (8) is fixed to a first surface (11A) via its part (4A) which displays the lower degree of adhesion, after which the surface (11A) bearing the said marker (8) is placed against the marking location (13) so that the part (1B) of the marker (8) with the greater degree of adhesion adheres to the said marking location (13) when the said first surface (11A) is moved away from the marking location (13), and that the marker (8) is transferred to the said marking location (13) when the said first surface (11A) is moved away from the marking location (13).

Description: A Process for Marking a Position, and an Arrangement for carrying out the Process The present invention relates to a process for mark¬ ing a position, particularly in locations which are not readily accessible. The main object of the present invention is primarily to provide a process of the above-mentioned kind whereby the desired position, particularly with concealed sur¬ faces such as arise with electrical wiring boxes, cabi¬ nets, bathroom articles, mirrors, light fittings, etc., the positionsfor which are usually difficult to mark, is quickly and effectively established without the need for laborious and time-consuming hole-making or measuring operations followed by marking out of the position data. The said object is achieved with a process accord¬ ing to the present invention which is mainly character- ised in that, after having established a marking part on a marker which has two parts with different degrees of adhesion, the said marker is fixed to a first surface via the part which has the lower degree of adhesion, after which the surface bearing the said marker is placed against the marking location so that the part of the mark¬ er with the greater degree of adhesion adheres to the said marking location, and that the marker is transferred to the said marking location when the said first surface is moved away from the marking location. A further object of the invention is to provide an arrangement which is suitable for carrying out the afore¬ said process. The said further object is achieved with an arrange¬ ment according to the invention for marking a position, particularly in locations which are not readily access¬ ible, which is mainly characterised in that a markerhas two separate parts with different degrees of adhesion. The invention is described in the following by way of several preferred embodiment examples, with reference to the accompanying drawings, on which Figure 1 is an exploded view of a marker arrange¬ ment according to the invention, -Figure 2 is a perspective view of a plurality of markers on a rollable supporting strip, Figure 3 shows the marker being used for marking holes for a handle, Figure -V shows the marker being used for marking to fix up a wall cabinet, Figure " shows the marker being used with a holder for marking the position of an electrical wiring box on a cladding element, Figure 6 shows a further embodiment of a holder which is suitable for marking the position of electrical installations by means of a marker according to the in¬ vention, Figure 7 shows another, different type of electri¬ cal wiring box for which the invention can be used, Figures 8-13 show various stages in the marking and mounting of an electrical box with a cladding element, and Figures 1 and 15 show, in perspective or from the side respectively, a further type of marker holder which is suitable for marking the position of a box according to the invention. A marking arrangement according to the invention, which is suitable for marking a position, particularly in locations which are not readily accessible, such as on a wall, a cupboard door, or a chest, for example, when the object of which the position is to be marked thereon obscures the intended marking location near the object, which may consist, for example, of a cupboard, an electri¬ cal installation fitting or a handle, consists of a fix¬ ing part 1 which preferably has a sheet-form surface area with two faces 1A and 1B respectively facing in opposite directions from each other. Expediently, the fixingpart ' BUREA OMPI is formed of a double-sided adhesive tape, preferably of the foaming-tape kind. One face 1A of the said fixing part 1 is covered by a permanent layer 2, such as a pro¬ tective paper, for example, which has at least one hole 3 stamped through the layer to the adhesive which is ap¬ plied to one face 1A of the fixing part 1. The other face 1B of the fixing part 1 is expediently covered by an easily removed protective foil 5 or a similar protective layer, preferably a siliconised foil, which adheres temporarily to the adhesive 6 located on the face 1B of the fixing part. A so-called "sight hole" 7. which may be located in the centre of the above-described marker 8 and extends through both the protective films 2 and 5 and through the fixing part 1, can act as the position-marking part of the marker, but other parts of the marker 8, such as the outer edges 8A, or outer corners 8B or some position mark 8C on the marker 8, would also be suitable for this purpose. The layer of adhesive -A which is exposed through the hole 3 in the layer 2 has a smaller surface area than the adhesive layer 6 which covers the face 1B of the fixing ' part and the two marking parts 1A and 1B therefore dis¬ play dissimilar levels of adhesion, . i.e. the lesser degree of adhesion is present at the said first surface -A which is exposed through the hole 3 . while the greater degree of adhesion is displayed by the part 1B of the fixingpart, which is preferably entirely covered with a coating of ad¬ hesive 6. Mass production of the marker 8 is expediently effect- ed as shown in Figure 2, by attaching one face of a strip 1 * of double-sided foaming tape which is preferably the width which it is desired the finished markers 8 should be to a protective paper strip 2* which has central holes 3 stamped out at appropriate intervals, and covering over i s other face with a strip of siliconised protective foil 5'. Expediently, after this the holes 3 are punched out OMPI ~~ through the marker strip 8' thus formed, while breaks 9 are punched between the individual markers 8 through the protective paper strip 2* and the strip of tape 1', up to the siliconised protective foil strip 5' which acts as a supporting web for the separate markers 8 which have thus been divided off. This siliconised web 5' . or a web 5' which has been treated with some other slip-substance, enables the required number of individual markers 8 to be peeled off easily from the said web 5 1 when they are to De used, from the marker web 8' which can preferably be made up into the form of a roll. In the embodiment ex¬ ample shown on the drawings the shape of the marker 8 is square, but the marker. can naturally also be made in any other suitable shape, when the need and require- ent for this exists. The use of the marker 8 is as follows, reference be¬ ing made primarily to Figure on the drawings: The marker 8 is attached with its chosen marking part, preferably the hole 7 . disposed so that the latter comes directly over the fixing holes 10 on the surface 11 on the rear face of the bathroom cabinet 11 which it is de¬ sired to fix up on an area of a wall 12 covered with tiles. By pressing the markers 8 against the said.first surface 11A they stick on the rear face 11A of the cabi- net 11 via the part A which is exposed through the res¬ pective hole 3. After this, the position where the cabi¬ net is to be fixed on the wall 12 is established, prefer¬ ably with a water-level, by pressing the rear face ofthe cabinet 11 with the markers 8 on it against the wall 12 so that the markers 8 come into position on the respec¬ tive marking places 13 and stick to the wall 12 under the effect of the adhesive layer 6 on the respective markers 8. When the cabinet 11 is moved away from the wall 12 so that the rear face 11A of the cabinet is moved away from the marking locations 13, the markers 8 are transferred to the wall 12 due to the fact that the adhesion degree. BUREA OMPI on the markers 8 is greater on the surface 1B which is placed against the wall 12. After the marking process bores, etc. for plugs 1 and fixing screws 15 can be made in the wall 12 where the chosen marker part indicates the place, preferably at the holes 7- The method is substantially the same when mounting a handle 16 which is shown in Figure 3 . for example, on a cupboard door using fixing screws, etc. screwed in from the inside of the door. In this instance, the markers 8 are attached via the adhesive part 4A to the respective ends 17, 18 of the handle so that when the handle is pressed in position up against the cupboard door 19 they are transferred onto the latter at the marking locations for the handle 16. By means of a holder 20, for example of the kind which is shown in Figure 5 . it is possible to determine quickly and exactly the position of a cut-out 21 which it is desired to produce directly in front of a location, particularly the location of an electrical installation device 22, in a cladding element such as a wall cladding panel 23. The holder 20 is formed of a plate, etc. which has centring cut-outs 24, 25, 26 distributed around its periphery, disposed in diametrically opposed pairs and preferably in the shape of keyholes. The circular entry passages 24A, 25A, 26A of the cut-outs can be pairwise of different sizes, and the distance between centres of the pairs of cut-outs 24 - 26 can differ, to enable the plate 20 to be centred on different sizes of standard¬ ised circular installation devices 22. By means of fix- ing screws 27 which are screwed into the actual electri¬ cal installation device 22 the plate 20 is attached by reception of the screws 27 . in the appropriate cut-out slots 24 - 26. and after rotation, in a position which is suit¬ able for marking the position of the device 22 as shown in Figure 8. After this a marker 8 is attached via the adhesive part 4A to the zone in the centre of the plate which is marked, for example by a raised area 28, etc. the shape of which expediently corresponds to the exter¬ nal shape of the marker 8. After the protective layer 5 is removed, if this has not been done before the marker 8 was applied to the holder plate 28, the wall panel 23 is placed in position in front of the electrical box 22, as shown in Figure 11. The marker 8 thus becomes attach¬ ed via its adhesive part 1B which displays the greater degree of adhesion to the rear face of the panel 23, so that a hole can subsequently be made with a box hole cut¬ ter 29, for example. The point 30 of the said box hole cutter 9 can be positioned in the correct position for making the hole, in the hole 7 in the marker 8 which is expediently located in the centre of the marker. When the hole has been made after moving the panel 23 awayfrom its temporary pressed-on position, the panel 23 can be fixed permanently, after removal of the holder 20, so that the electrical box 22 is positioned directly behind the cut-out 21 through the panel 23. Other types of holder can be used for box marking, such as a holder 3 ? which is shown in Figure 6 on the drawings, for example, having clamping devices 32 in the form of rollers on its inside face, for example, and the position of which can be adjusted by means of an adjust- ment arrangement, for example of the eccentric type, to the required hole width for the electrical box 22. A holder 33 is shown in Figures 14 - 15 which has a central protruberance 34 to which a marker 8" can be attached via its adhesive part which consists, for ex- ample, of stickly tape or adhesive and which, as shown in Figure 15, has a smaller adhesive area 35 over a cut¬ out hole 36 made through a marker holder part 8"A up to thesaid adhesive area 35 . A removable protective layer 38 which is provided with a gripping edge 37 and which normally covers and protects an ahesive layer 39 which faces in the opposite direction from the said first adhesive area 35 is designed to be removed when using the said marker 8" for marking so that when pressed on a wall panel the said layer 39 sticks to it and overcomes the adhesion of the adhesion area 35. Finally, Figure 7 shows an electrical box 40, the so-called "plaster cover" 41 of which acts during mark¬ ing as a holder in the above-mentioned way, but with the difference that the markers 8 which are used and which are of the type which was described above with reference to Figures 1 and 2 amongst others, are attached, for ex¬ ample, to the corner zones 41A, 413, 410, 41D of the said cover, or some other suitable points, for example on its periphery; these fixing points can be indicated on the cover 41 from the outset by marking of a suitable kind, such as by projecting or recessed marking indications42, so that the markers 8 which are transferred onto a wall panel, for example, mark the corners of a cut-out which is then sawn out, for example, through the said panel. Examples of some applications where marking accord- ing to the invention is appropriate are as follows: Marking holes for handles with integral tapped sleeves where the screws are screwed in from the door or drawer. Marking the position of switches and wall cut-outs near mouldings for electric installations. All position marking for "equipment" with a larger ■ outer cover serving as concealment for the screw fixings. Such equipment is especially difficult to mount near to mouldings, cupboards or wall corners when the cover is in position, but with this invention it is possible to effect marking with the cover in place, so that it is easy to achieve the desired positioning. Light fittings on the ceiling, for example, where the marker can serve as a third arm, in that markers have been placed on the fitting so that it is possible to use both arms for positioning the fitting. When the H3 R£A fitting is pressed against the ceiling, for example,and the markers transferred, the screws for it can be mounted directly, when a keyhole type of mounting is involved. In concrete, for example, holes are bored in accordance with the markers and it is then possible to insert the plugs and screws. In wood but still with a keyhole mount¬ ing, screws can be screwed in, after which the fitting can be mounted easily. For mounting lighting over sinks the outer edge of the fitting should be seated in line with the outside of a wall cabinet which is easy to accomplish as both arms are free to guide the fitting. When mounting fittings on walls concealed keyhole mountings are often used for the sake of appearance. Such mounting is easy to effect with this marker, as the fit¬ ting can be positioned, its position marked and then the mounting screws can simply be fixed in. Mirrors and pictures are often designed to be mounted on some kind of hook on the wall via a loose cord on the rear. With this kind of mounting the cord can be stretch¬ ed up to a point on the rear side of the mirror or picture and a marker positioned there. Then the mirror or pic ¬ ture can be put in position and the marker transferred to where it is necessary for the hook to be positioned, by pressing it against the wall. This method is suitable for hanging pictures when it is desired that either their upper or their lower edge should be placedin a line and the suspension points vary. When mounting bathroom articles on tiles it is hard to place a mark on the hard surface. This is facilitated by means of the invention since the marker gives a clear position marking while at the same time a third arm is obtained. When mounting loudspeakers in vehicle doors it is difficult to see the boundaries of what hollow space there is, due to the fact that the door cladding in which O - 9 - the holes should be made obstructs all measurement- aking. It is now possible to place a suitable number of markers on the boundaries of the door frame which forms the limits within which the loudspeaker can be positioned. The door cladding is then pressed in place and the markers are transferred onto it. From this it is then possible to make the appropriate holes so that the loudspeaker has room. The invention is not limited to the embodiment ex- amples described above and shown on the drawings, but its details may be modified within the frame of the following Patent Claims. It would be possible, for example, instead of producing the dissimilar degrees of adhesion on the marker parts as indicated, by having differently di en- sioned areas of adhesive, to use instead adhesi es, for example, with different adhesion properties on areas of the same size on the marker.
