INTERIOR LINING FOR THE RESTORATION OF ROOMS, IN PARTICULAR BATHROOMS, AS WELL AS A METHOD FOR RESTORING SUCH ROOMS

Description

Technical Field of the Invention

[0001] This invention relates to an interior lining for the restoration of rooms, in particular bathrooms, comprising a shell composed of a floor unit, a ceiling unit as well as a plurality of walls constructed by pre-fabricated boards extending between said units, each one of said components included in the shell being arranged at a certain distance inside the corresponding parts of a room set free from mechanical services in order to guarantee that the shell is surrounded by air-gaps all around, and the shell being kept in place in the room by means of sets of fastening profiles, located at different levels, applied on the inside of the room walls, viz. a lower profile set placed close to the floor of the room and an upper profile set placed at a distance below the ceiling of the room.

Background of the Invention and Prior Art

[0002] When restoring bathrooms in blocks of flats, there is a marked desire, not only from the landlord, but also from the tenant that the work should be carried out in a short time, more precisely preferably in less than 48 hours. Namely, if the work takes a long time, the tenant will have to move out of his flat. This is costly for the landlord, above all, and entails considerable practical worries for the tenant. Also house-owners have the same desire, in particular when external workmen are hired. A condition of handling such extremely short completion periods as 48 hours is that the walls of the new interior lining are made of pre-fabricated wall boards and not of tiled walls which are built up manually by means of individual tiles and mortar.

[0003] With the purpose of rendering the restoration of bathrooms more effective, there has earlier been developed different types of pre-fabricated tiled wall boards, which may be hung on rails fixed to the room walls as in GB-A-2 019 930, or mounted by means of screws, i.e. without using mortar and/or jointing sealing compound. Inter alia, by SE 9103374-6 a tiled wall board is known which is composed of a frame made of moulded plate and a covering layer of tiles applied in factory onto an outside thereof, the board having, along the opposite long side edges thereof, grooves and tenons formed in such a way that the boards may be fastened against a wall therebehind by means of hidden screws. However, a disadvantage of this known wall board has proved to be the fact that the length thereof, in the main, corresponds to conventional room height (i.e. 2,0 - 2,2 m). This not only means that the boards as such become heavy (25-35 kg) and difficult to handle, but also that various exterior bathroom details, such as water taps and pipes therefor, towel hangers, etc., have to be fastened afterwards in the mounted boards; in practice by means of through screws and/or expansion-shell bolts. In other words, holes must be drilled afterwards in the boards. This means that there is an obvious risk for water penetration through the completed interior lining. Furthermore, the room-high length of the individual board means that there is a latent risk for crack formation in the tiles and the tile joints inasmuch that the board - by the heavy weight thereof - may be exposed to considerable bending stresses in connection with transportation and handling. Also, the staff performing the restoration is exposed to ergonomic stresses in connection with lifting and carrying the heavy boards.

Objects and Features of the Invention

[0004] This invention aims at obviating the above-mentioned disadvantages of previously known techniques and at creating an interior lining for the restoration of, in particular, bathrooms of an improved design. Thus, a basic object is to create an interior lining the components of which, in particular wall boards, are easy to handle and may be mounted without afterwards having to be broken through by drilling holes or the like for fastening water taps and similar details. A further object is to create an interior lining the wall boards of which do not require screws or similar fastening elements for the mounting thereof. An object is also to create an interior lining which is aesthetically attractive and which offers a large flexibility in respect of requisite piping in the form of tap water pipes as well as evacuation pipes, e.g. from a bath tub and/or a basin. The interior lining should also be able to be installed quickly as well as stand moisture load without causing formation of mildew or other moisture damage. Another object is to create an interior lining the various components of which may be aligned in horizontal and vertical planes respectively in an easy way even if the existing room has uneven floors and walls.

[0005] According to the invention, at least the primary object is attained by the features defined in the characterising clause of claim 1. Preferred embodiments of the interior lining for restoration according to the invention are furthermore defined in the dependent claims 2-7.

[0006] In addition to the interior lining as such, the invention also relates to a method for restoring such rooms as bathrooms. The features of the method according to the invention are evident from claims 8 and 9.

Detailed Description of a Preferred Embodiment of the Invention

[0008] In fig 1 an existing, restoration-prepared bathroom is shown which is delimited by a naked floor 1, a ceiling frame work 2 as well as a number of (usually four) walls 3, 3' of which two are shown in the figure. In fig 1 the following measures have been taken. An earlier existing floor drain 4 has been eliminated, e.g. by being filled with mortar. A long narrow hole 5 has been recessed in the frame work 1, more precisely to hold a floor drain unit. Through this hole, also a down pipe 6 for waste water may be drawn (as well as for tap water pipes although these are not shown in fig 1).

[0009] Furthermore, the inner sides of the walls 3, 3' have been set free from earlier existing details, such as holders, hangers, taps, etc. Surface material possibly being loose has also been removed from the walls.

[0010] In fig 1 is also shown how certain components of the new interior lining have been installed. More precisely, three sets of fastening profiles 7, 8, 9, located at different levels, have been applied on the walls, as well as a corner profile 10 in the transition between the two existing walls 3, 3'.

[0011] In fig 2 is shown how a floor drain unit 11 has been mounted in the hole 5. This unit is in the form of a plate with a pipe to lead waste water from an inlet 12 to the down pipe 6. On top of the box there is a border 13 for a future connection of a particular cassette.

[0012] In fig 3 a cassette is shown mounted on the floor drain unit 11 which cassette comprises, in the preferred embodiment, two halves or parts 14, 14'. The cassette parts may in a suitable way (not shown) be fastened by the fastening profiles 7, 8, 9, and contain different working components such as a flushing water tank for a toilet, heating elements for warming towels, pipes and couplings for the connection of a tap water pipe, etc. The cassette may in its entirety be located in the vicinity of a corner of the room as indicated in fig 3. It should be noted that the upper part of the cassette ends on a level with the upper fastening profile B.

[0013] Furthermore, fig 3 illustrates how a number of prefabricated wall part boards 15, lined with tiles have been applied on the walls, more precisely in an upper set between the upper fastening profile 8 and the intermediate fastening profile 9 and a lower set between the intermediate fastening profile 9 and the lower fastening profile 7. A particular box profile 16 has also been mounted on the intermediate fastening profile 9 applied on the wall 3, said box profile being shown in detail in figures 14 and 15. It is indicated on the intermediate fastening profile 9, which is fixed on the wall 3', how a covering border fillet 17 has been mounted. The nature of said border fillet may be seen in fig 11.

[0014] In fig 4 a further working step is shown in which the walls have been completely lined with wall part boards 15, and a floor unit 18 being installed on the floor frame work 1. Furthermore, a ceiling unit 19 has been mounted on the upper fastening profiles 8.

[0015] The floor unit 18 is composed of a number of part boards 18', having elongated, rectangular form. In practice, said floor part boards may have a width within the range of 30-60 cm, the boards extending perpendicularly to the wall 3 in connection to which the floor drain unit 11 is connected. Each part board comprises a plurality of level adjusting elements 20 which are shown in detail in fig 10. In practice, the element 20 may advantageously consist of an externally threaded cage having an internal key grip 21 and a bottom in which an expansion screw 22 may be fixed. The cage is screwed down through a hole in the floor board 18' which in the actual case may be levelled through rotation of the cage. After completed levelling, the top part of the cage is cut off, the expansion screw 22 fixing the same while making lifting of the floor board impossible.

[0016] Also the ceiling unit 19 is advantageously composed of a number of long narrow, rectangular part boards 19' carried by the upper set of fastening profiles 8.

[0017] Reference is now made to fig 5 which constitutes an exploded view illustrating vital components included in the interior lining according to the invention. It may be seen in the figure how the above-mentioned wall part boards 15 have a rectangular form. In practice, the individual part board may have a height of 100 cm and a width of 60 cm as well as being composed of a carrier or frame 23 of moulded plate as well as a layer of tiles 24 on the outside. Said tiles may have the dimensions 20 x 15 cm, the tiles being arranged in five vertically separated rows with four tiles in each row. One part board of this kind has in practice a weight within the range of 12-15 kg. The part boards 15 have, along the opposite long side edges thereof, grooves for accommodation of particular edge lists 25.

[0018] In fig 5 it may furthermore be seen how all fastening profiles 7, 8, 9 are fastened by means of screws 26 while using particular spacers 27 between the inner wall of the room and the inside of the fastening profile. Said spacers may advantageously consist of the well-known type which has an oblique slit making it possible to hang the spacer on a provisionally fastened screw in the wall. The spacer may have a relatively large surface, e.g. 10-30 cm², and a thickness of 1 à 2 mm. Such spacers make an easy alignment of the fastening profiles possible so that the same are located in a common vertical plane outside each individual wall. Thus, in case irregularities would be found on the existing wall, a number of spacers may be applied between the individual fastening profile and the bottom of the irregularity. In this way, it is guaranteed in a reliable way that the straight original shape of the fastening profile is preserved even if said profile is brought against very irregular wall surfaces. Alignment of the profiles is made already in connection with the initial installation step which is illustrated in fig 1.

[0019] In fig 5 is furthermore shown a tube profile the nature of which is better seen in fig 10. Holes 29 for drain pipes, e.g. from a basin and a bathtub respectively, are recessed in an upper flange of said tube profile. A lower hole (not shown) in the lower flange of the tube profile is, in practice, connected to the inlet 12 of the floor drain unit 11.

[0020] Reference is now made to figures 7 and 8 which in detail show the design of the upper fastening profile 8. More precisely, said profile consists of a hole profile which, in a mounted state, comprises a vertical rib 30 from which two, vertically separated, flanges 31, 32 extend of which the upper flange 31 is wider than the lower one and has the purpose of carrying the wall boards 19'. The lower flange 32 has a width which is only a little larger than the thickness of each wall part board 15. By the edge distanced from the rib 30, the lower flange 32 transforms into a downwardly directed skirt 33 which, together with the rib 30, delimits a groove 34. The skirt 33 transforms, in turn, at the lower edge thereof, into an oblique intermediate flange 35 connected to the free end edge of the upper flange 31, said intermediate flange having a form similar to the form of a conventional wooden corner moulding. As may be clearly seen in fig 8, the depth of the groove 34 is so large that the upper edge of the wall part board 15 is on a level below the lower flange 32 in the mounted state of the board. In fig 8 it may furthermore be seen how the vertical rib 30 of the fastening profile 8 is distanced from the inner wall 3 of the room by means of spacers 27.

[0021] In fig 9 it may be seen how the lower fastening profile 7 is cross-section-wise in the main L-shaped and comprises a vertically, relatively wide rib 36 as well as a flange 37 protruding perpendicularly from the lower edge thereof. The angle between the rib and the flange is most suitably 90°. A cross-section-wise substantially T-shaped, border-like portion 38 is formed in the area of the top part of the rib. Said T-border portion has an upper flange 39 which, together with the rib, defines a groove 40 opening upwards, as well as a lower flange 41 which, together with the rib, defines a groove 42 opening downwards. A lower grip flange 43 may be received in the upper groove 40 on the individual wall part board, as is shown in fig 10. An upper grip flange 44 may be received in the lower groove 42 on the above-mentioned tube profile 28.

[0022] As may be seen in fig 10, the above-mentioned grip flange 43 may consist of a bent edge portion of the plate 23 which form the frame for the layer of tiles 24. In other words, the upper flange 39 on the T-border portion 38 grips in between the grip flange 43 and the lower edge of the layer of tiles 24.

[0023] In fig 10 it may be furthermore seen how the outermost edge portion of the individual floor board 18' is carried by the lower, perpendicular flange 37 of the fastening profile 7, possibly via an interlayer 45. Furthermore, it may be seen how a mat 46 put onto the floor unit is drawn up a bit along the vertical rib 36 of the fastening profile. In order to make this possible, the upper portion of the back piece of the box profile 28 is laterally displaced in relation to the rest of the back, whereby a gap 47 is formed to house the drawn-up edge portion of the mat.

[0024] Reference is now made to figures 11-13 in which it may be seen how the intermediate fastening profile 9 comprises, in an applied state, a vertical rib 48 which has, on one side thereof, two vertically separated, cross-section-wise substantially T-shaped, border-like portions 49, 50. The upper T-border portion 49 has a flange 51 directed downwards which is wider than a corresponding upwardly directed flange 52 of the lower T-border portion 50. The flange 51 forms, together with the rib 48, a groove 53 which is deeper than the groove 54 delimited by the rib and the flange 52. Said grooves 53, 54 are intended to co-operate with grip flanges 55, 56 in the form of bent edge portions of a plate 17' which forms a carrier for a layer 17" of tiles included in the border fillet 17. The distance between the free edges of the grip flanges 55, 56 is somewhat smaller than the distance between the bottoms of the grooves 53, 54. By the fact that the upper groove 53 is deeper than the lower groove 54, the border fillet may be hooked into the intermediate fastening profile 9 owing to the upper grip flange 55 first being brought up into the upper groove 53, and then the lower flange 56 may be dropped down into the groove 54.

[0025] The two T-border portions 49, 50 furthermore have upper and lower respectively flanges 57, 58, which, together with the rib 48, define two additional grooves 59 and 60 respectively. Lower grip flanges 43 of the upper wall part boards 15 may be inserted in the groove 59, while upper grip flanges 43 of the wall part boards in the lower set of boards may be inserted from below and up into the groove 60. Also the intermediate fastening profile 9 is fixed against the wall being behind through spacers 27 and by means of screws 26.

[0026] The box profile 16 shown in fig 14 comprises a top piece 61, a back piece 62, a bottom piece 63 and a front piece 64. A protruding part having upper and lower grip flanges 55' and 56' respectively is formed in connection with the upper part of the back piece. Said grip flanges may be applied in the grooves 53, 54 in the same way as the corresponding grip flanges of the border fillet 17.

[0027] In the front piece 64 a long narrow, longitudinal opening 65 is recessed which, at the top, is defined by a bead in which a groove 53' is included and which, at the bottom, adjoins a lower groove 54'. It should be evident that a cover strip 17 may be applied in and cover the opening 65 by the fact that the grip flanges 55, 56 are hooked into the grooves 53', 54', as is shown in fig 15. Pipes 66 for tap water in the form of hot water as well as cold water may be included in the box profile 16. In the bottom piece 63 of the box profile holes may be recessed for water taps of the kind which are designated 67, 67' in fig 6.

[0028] The edge list 25 shown in figures 16-19 comprises a back piece 68 and a suitably central bead 69 protruding therefrom which, at a distance from the back piece, has two laterally protruding projections 70, 70' for engagement with grooves 71 in the vertical long side edges of the wall part boards 15. Said grooves 71 are formed between the layer of tiles and a bent edge portion 43 on the plate 23 forming the carrier of the board. It should be particularly noted that the intermediate bead 69 protrudes a bit from the projections 70, 70', said protruding piece forming a spacing element which exactly determines the width of the joint between adjacent wall part boards. In fig 19 it may be seen how the projections or flanges 70, 70' are longer than the back piece 68, whereby protruding end portions are formed which may be applied in the grooves 60, 40 in the fastening profiles 9, 7 and in the grooves 34, 59 in the profiles 8, 9.

[0029] Reference is now made to figures 20-25 which illustrate how the corner profile 10 includes two flanges 74 extending mutually perpendicularly and between which there is an intermediate piece 75. Said intermediate piece has the form of a hole profile which is longer than the angle flanges 74 as may be seen in fig 24. In this way, upper and lower end portions 75', 75" are formed which have slits 76 for connection with the upper and lower fastening profiles 8, 7. The intermediate piece 75 has, on the inside thereof, a groove 77 delimited between two beads for snap-in fastening of a cross-section-wise arc-shaped cover strip 78, more precisely by the fact that a central batten 79 is pressed into the groove 77. In fig 25 it may be seen how the corner profile 73 is fastened in the inner corner between the walls 3, 3' by means of screws and spacers. After the wall part boards in question (not shown) having been connected to the comer profile, the cover strip 78 is snapped-in to hide the joint gap between the part boards.

[0030] An analogue corner profile 80 for outer corners is shown in fig 27. Also in this case, the corner profile comprises a groove 81 delimited between beads in which an intermediate batten 82 to a cover strip 83 may be snapped-in.

[0031] Finally, reference is made to fig 6 which illustrates the ready-made interior lining. Unlike fig 4, fig 6 shows how the floor mat 46 has been applied to the floor unit built up by the floor boards 18'. In addition, a toilet 84 has been applied to the cassette 14. Furthermore, a basin 85, together with the appurtenant under-cupboard, has been installed, as well as a bathtub 86. Also other, not shown details may be applied on the walls.

[0032] The installation of the various components included in the interior lining according to the invention takes place in the following order.

[0033] After having cleaned the existing bathroom from older details, the fastening profiles 7, 8, 9 as well as the corner profiles 10 are fixed, as shown in fig 1. Then the floor drain unit 11 is mounted according to fig 2 and the cassette halves 14, 14' thereon. In the next step, the tile-covered wall part boards 15 are hooked on one by one, first in the lower set between the intermediate profiles 9 and the lower fastening profiles 7 and then in the upper set between the upper fastening profiles 8 and the intermediate fastening profiles 9. Edge lists 25 of the kind which are shown in fig 16 are inserted between adjacent part boards. A box profile 16 is hooked on, on one hand on the box profile 16 and on the other hand on the intermediate fastening profile 9 on the wall 3'. Furthermore, the floor boards 18' are mounted on the existing floor frame work 1 and are levelled by means of the level adjustment elements 20 so that a correct inclination towards the floor drain unit 11 is obtained. The ceiling boards 19' are put up on the upper fastening profiles 8 to form a ceiling as shown in fig 4. Furthermore, the cover strips 78 are applied by snap-in fastening on the corner profiles 10. Finally, the toilet 84, the basin 85 and the bathtub 86 are installed.

The Advantages of the Invention

[0034] By constructing the walls of the interior lining from part boards of a limited length or height in two vertically separated sets, it is gained that the weight of the boards is limited at the same time as different bathroom details, such as water taps may be applied in an easy and suitable way on the intermediate fastening profile being at waist-height. This means that the wall boards do not need to be drilled through afterwards so as to enable the putting up of the required details (in this connection, it should be mentioned that special wall part boards to carry the basin may be pre-fabricated with holders for the basin). Furthermore, the completed interior lining obtains an aesthetically attractive design by the existence of the border fillet between the upper and the lower sets of wall part boards. As indicated in fig 5, said border fillets 17 may be made with special patterns which are in contrast to otherwise one-coloured tiles included in the part boards 15. By the fact that not only the proper wall part boards but also all fastening profiles 7, 8, 9 are fastened at a distance from the existing inner wall, it is guaranteed that air may freely sweep around the shell formed by the wall boards, the ceiling unit and the floor unit from all sides. This, in turn, guarantees that formation of mildew and other moisture damage is effectively counter-acted. Furthermore, the interior lining according to the invention permits that the various components may be mounted in an utterly quick and effective way, above all by the fact that the wall part boards may be applied merely by the simple measure of being hooked onto the fastening profiles; i.e. without any need of screws or the like.

Feasible Modifications of the Invention

[0035] The invention is not solely restricted to the embodiment described and shown in the drawings. Although wall part boards lined with tiles are preferred, it is thus, in practice, conceivable to use part boards lined or surface-treated in another way. Furthermore, the invention is also applicable in connection with restoring other rooms than bathrooms.
