Description
Proceeding and means to fasten mounting element into a wall The present invention relates to a proceeding for, in connection with hole making in a wall, for the mounting of items on the moisture-proof walls of a wet area by means of an expandable mounting element, providing sealing of the hole.
The requirements and desire to moisture-proof bathrooms and other wet areas have successively augmented dur-ing the years. The insurance industry together with different professional and industrial organizations work continuously with disseminating information about how water damage can be prevented. In spite of this, water damage in bathrooms is still a significant problem, and only in Sweden, it corresponds to a cost of approx. SEK 39 million per week.
Among private persons, the striving to prevent damage has increased as the understanding that the damage may become both expensive and trying has become more apparent. The attitude among private persons in combination with the interest of the insurance companies make that today there is a market for new, more reliable and simpler solutions that can provide for this need.
The reliability in a bathroom relies upon its waterproof layer. Any mounting that destroys this waterproof layer requires an accurate repair. Instructions for attachment upon mounting vary depending on what and where to be mounted.
Moreover, the workmanship varies depending on craftsman, occu-pational group or private person.
The development of a standardized attachment device that is impossible to vary and that is applicable to all mounting steps would therefore be desirable in order to guaran-tee that the waterproof layer always becomes correctly restored independently of the fitter or manufacturer.

The reliability in a bathroom relies upon its waterproof layer. Any mounting that destroys this waterproof layer requires an accurate repair. Instructions for attachment upon mounting vary depending on what and where to be mounted.
Moreover, the workmanship varies depending on craftsman, occu-pational group or private person.
The development of a standardized attachment device that is impossible to vary and that is applicable to all mounting steps would therefore be desirable in order to guaran-tee that the waterproof layer always becomes correctly restored independently of the fitter or manufacturer.
Known examples of anchoring means for other at-tachment items are shown in, among others, DE 3,931,683 Al, which discloses an anchor bolt (12) having an expansion sleeve (10), DE 4,106,507 Al, which discloses a mounting bolt (2) for vehicles and also provided with an expandable sleeve (7), and CA 2,270,570 A, which discloses a bolt (10) having an expand-able sleeve (12) situated far out on the threads (18) of the bolt.
All attachments in the wet zone of the wet area should be made in solid structure, e.g., in concrete, in joists, or in a nogging piece. An attachment must not be made solely in a wallboard. This means that when concrete walls are lacking, the position of all fittings has to be predetermined before wet area boards are to be mounted.
At each planned attachment, a postjacent nog-ging piece is mounted if a joist is lacking. A disadvantage of not being able to make a planned attachment, without a postja-cent solid structure, is that the exact position of fittings may be difficult to foresee as well as that a desire to com-plete with new things may arise sometime later on.
Another disadvantage is that, in connection with the framing of the bathroom, a nogging piece, for in-stance, may also be missed to be mounted. There is no possibil-ity of putting right a missing nogging piece without needing to dismount a wall in question into its stud work. Attachments us-ing a traditional expander can be made without a solid struc-ture but cannot be applied in wet rooms because of the water-proof layer of the wet room being damaged and thereby losing its sealing capacity.
None of these known solutions provides a liq-uid-proof fixing. Usually, silicone is utilized for securing holes against moisture, but not even this gives a reliable sealing, particularly not when screws have been removed from items that previously have been mounted in and on, respec-tively, the wall.
Therefore, the main object of the present in-vention is primarily the development of a system and a wet area expander that are applicable to the walls of wet areas and to mounting steps therefor, and that allow a mounting without a postjacent solid structure without destroying the function of the waterproof layer of the wet room.
Said object is achieved by means of a proceed-ing according to the invention that essentially is character-ized in that, in addition to providing an expansion of the mounting element behind said wall, there is also provided an internal expansion of the mounting element in the receiving hole of the mounting element in question in the wall, as well as there is furthermore provided a liquid-proof cover around the entire mounting element in question introduced and expand-ing in said receiving hole, and by means of means according to the invention, respectively, that essentially is characterized in that an expansion sleeve has the ability to expand at a dis-tance from each other, as seen along the length extension of the sleeve, that said expansion is arranged to occur externally further in on the sleeve and internally further out on the sleeve, as well as that an expandable, preferably elastic liq-uid-proof cover surrounds said sleeve from the outer portion thereof.
The invention is also comprised of an addi-tional proceeding that is characterized in that, in addition to providing an expansion of the mounting element behind said wall, there is also provided an internal expansion of the mounting element in the receiving hole of the mounting element in question in the wall, as well as there is furthermore pro-vided a liquid-proofing around the mounting element in question introduced and expanding in said receiving hole.
All attachments in the wet zone of the wet area should be made in solid structure, e.g., in concrete, in joists, or in a nogging piece. An attachment must not be made solely in a wallboard. This means that when concrete walls are lacking, the position of all fittings has to be predetermined before wet area boards are to be mounted.

The invention is also comprised of an addi-tional proceeding that is characterized in that, in addition to providing an expansion of the mounting element behind said wall, there is also provided an internal expansion of the mounting element in the receiving hole of the mounting element in question in the wall, as well as there is furthermore pro-vided a liquid-proofing around the mounting element in question introduced and expanding in said receiving hole.
The invention is also comprised of an addi-tional means for carrying out a proceeding for, in connection with hole making in a wall, for the mounting of items on the moisture-proof walls of a wet area by means of an expandable mounting element, providing sealing of the hole.
A said means is characterized in that an expan-sion sleeve has the ability to expand at a distance from each other, as seen along the length extension of the sleeve, that said expansion is arranged to occur externally further in on the sleeve and internally further out on the sleeve, as well as that an expandable, preferably elastic liquid-proof cover sur-rounds said sleeve from the outer portion thereof.
Upon attachment, the expansion sleeve termed as the bathroom expander or the expander plug is applied in a pre-drilled hole and mounting pliers are used in a known way for establishing a correct expansion in the most reliable way. Now, the expansion occurs simultaneously on two parts of the ex-pander plug, on one hand at the back of the hole and the wall, and on the other hand inside the hole. The expansion in the hole is a result of the expander being cut and that there is a cast protrusion inside the front part of the bathroom expander.
The mounting tool is placed between the head of the screw and the washer. Pressure is applied in order to get the rear part of the bathroom expander to move toward the mouth of the hole.
The effect becomes that also the internal cylinder is pushed forward and presses the cast protrusions against the edges of the pre-drilled hole and the front part expands. The front ex-pansion is regulated by adapting the heights of the cast pro-trusions in the manufacturing. The bathroom expander has also an expandable metallic or an elastic polymeric covering that follows the expansion and together with suitable compound, for instance Racofix or silicone , seals the hole in a liquid-proof way. It is the front expansion inside the hole that al-lows the waterproof layer to become restored.
In the following, the invention is described in the form of a number of preferred embodiment examples, ref-5 erence being made to the drawings, in which Figs. 1-15 show a first embodiment example, wherein Fig. 1 shows in perspective and schematically an expanded mounting element, Fig 2 shows the mounting element as seen from the side, Fig. 3 shows a section along the line III-III

According to a first embodiment of the present invention, a proceeding according to the present invention re-fers to, in connection with hole making in a wall 1, for the mounting of items, e.g., sanitary equipment, cupboards, towel rails, mirrors and other necessary items, that are desired to be placed in bathrooms and other suitable wet areas on the moisture-proof walls 1 in question by means of an expandable mounting element 2, the provision of efficient sealing of the hole 3 in question for the mounting element 2 in a reliable and efficient way. Said proceeding involves that, in addition to providing an expansion I of the mounting element 2 behind said wall 1, there is also provided an internal expansion II of the mounting element 2 in the receiving hole 3 of the mounting ele-ment 2 in question in the wall 1, as well as there is further-more provided a liquid-proof III cover 4 around the entire mounting element 2 in question introduced and expanding in said receiving hole 3.
According to the invention, it is furthermore possible to allow an applied expandable compound (not shown) surround the liquid-proof III cover 4 and seal the hole 3.
A said indicated proceeding is both simple and efficient in terms of structure as well as use.
Means for carrying out an indicated proceeding for, in connection with hole making in a wall 1, for the mount-ing of items on the moisture-proof walls 1 of a wet area 5 by means of an expandable mounting element 2, providing sealing of the hole 3 according to the above mentioned involves that an expansion sleeve 6 has the ability to expand I; II at a mutual distance A from each other, as seen along the length extension 7 of the sleeve. Said expansion I; II is arranged to occur ex-ternally on the sleeve further in on the sleeve 6 as seen in the direction from the rear end 6A of the sleeve and internally further out on the sleeve 6, as well as that a metallic expand-able or an elastic liquid-proof cover 4 surrounds said sleeve 6 and a pressure part 8 connectable thereto in the direction from the outer rear portion 6A thereof and around the circumference of the entire sleeve as well as in a liquid-proof way around the front inner face portion 6B thereof and around the face portion of the pressure part 8.
Preferably, said cover 4 consists of latex rub-ber, plastic or another similar expandable and air- and liquid-proof material. In the case of a metallic expandable cover 4, said metal is formed of aluminium that has good liquid-proofing capacity.
Internally in the expansion sleeve 6, a sleeve-shaped said pressure part 8 closed in the inner end 8A is re-ceivable and that is provided with internal threads 9. Said pressure part 8 is attached to the expansion sleeve 6, for in-stance by welding, agglutination, etc., at the area of the shoulder 32 of the pressure part and the end 33 of the sleeve 6 when the parts 6, 8 are assembled. On said sleeve 6, separated groups 10, 11 having expandable parts 10A, 10B ...; 11A, 11B... are situated, and preferably said expandable parts 10A...; 11A... are formed of perforations in the cover of the sleeve 6.
Internally in the sleeve 6, at the area of the rear group 11 of perforations, a thickened portion 12 of the sleeve 6 is arranged, preferably in the form of parallel pads 12A, 12B, 12C,... 12n situated at a mutual distance from each other, as seen along the circumference of the sleeve.
Said pressure part 8 has, at one end 8B
thereof, a rear stop part 13 at an area 14 of a thinner portion of the pressure part 8, and which stop part 13 is arranged to co-operate with the front end portion 6B of the sleeve for the provision of expansion of front expandable parts as well as rear expandable parts when distancing the screw 15 received therein and the sleeve 6 in its longitudinal direction by means of mounting pliers in a known way.
Around the circumference of said pressure part 8, a number of chamfers 30 are arranged, extending in the length extension 31 of the pressure part 8. Said chamfers 30 are arranged to strengthen the expander 6 so that it is not urged to be turned without expansion occurring in the desired direction and in the correct way.
Said elastic liquid-proof cover 4, which is ar-ranged to surround both the sleeve 6 and the pressure part 8, may be formed of a sleeve-shaped rubber or plastic bag, and this is arranged to be threaded onto the sleeve 6 and the pres-sure part 8 before the same are introduced into the drill hole 3 in the direction from the wet area 5 in question as a joint unit. The cover may alternatively be formed of a liquid-proof metallic cover that is expandable. For instance, the cover may consist of aluminium that may be in the form of a corrugated liquid-proof cover that can expand into the desired shape.
Internally in the expansion sleeve 6, a said screw 15 is arranged to be screwed in and received therein to the major part for carrying the intended attachment item. A re-action washer 16 is threaded on said screw 15 inside the screw head 17, and between which mounting pliers are arranged to act upon tightening and expansion of the front expandable portion 10 of the expander by means of the mounting pliers in a known way after the screwing-in of screws 15 into the mounting ele-ment, in threads 9 at the rear end 8B of the pressure part 8, which is introduced with the tapering part 14 thereof into the internal reception space 18 of the mounting element 2.
The part of the mounting element 2 manufactured and formed of metal as an expansion sleeve 6 is preferably made from a flat sheet of plastic or sheet-metal plate 19 that is provided with a number of longitudinal parallel through perfo-rations 11 as well as internal pads 12A, 12B in the wall of the convolutable sheet 19. Special threads are not needed now on said sleeve 6, but the threads 9 are instead arranged in the pressure part 8, which is unturnably attached to the sleeve 6.
The embodiment of the invention that is shown as a second example in the drawings in Figs. 16-23 differs from the embodiment described above of proceeding and means for at-taching mounting elements in a wall foremost by the expansion as well as by the liquid-proof cover of the mounting element.

The circumference of said pressure part 8 is identical to the circumference of the end co-operatable portion 156 of the expansion sleeve 106.
The nature and function of the invention should have been clear from what has been described above and shown in the drawings, and the invention is naturally not limited to the embodiments described above and shown in the accompanying draw-ings. Modifications are feasible, particularly as for the na-ture of the different parts, or by using an equivalent tech-nique, without departing from the protection area of the inven-tion, such as it is defined in the claims.
A said means is characterized in that an expan-sion sleeve has the ability to expand at a distance from each other, as seen along the length extension of the sleeve, that said expansion is arranged to occur externally further in on the sleeve and internally further out on the sleeve, as well as that an expandable, preferably elastic liquid-proof cover sur-rounds said sleeve from the outer portion thereof.
Upon attachment, the expansion sleeve termed as the bathroom expander or the expander plug is applied in a pre-drilled hole and mounting pliers are used in a known way for establishing a correct expansion in the most reliable way. Now, the expansion occurs simultaneously on two parts of the ex-pander plug, on one hand at the back of the hole and the wall, and on the other hand inside the hole. The expansion in the hole is a result of the expander being cut and that there is a cast protrusion inside the front part of the bathroom expander.
The mounting tool is placed between the head of the screw and the washer. Pressure is applied in order to get the rear part of the bathroom expander to move toward the mouth of the hole.
The effect becomes that also the internal cylinder is pushed forward and presses the cast protrusions against the edges of the pre-drilled hole and the front part expands. The front ex-pansion is regulated by adapting the heights of the cast pro-trusions in the manufacturing. The bathroom expander has also an expandable metallic or an elastic polymeric covering that follows the expansion and together with suitable compound, for instance Racofix or silicone , seals the hole in a liquid-proof way. It is the front expansion inside the hole that al-lows the waterproof layer to become restored.
