Abstract

A telescopic profile system for preparing a skeleton (2) for supporting panels (3, 4, 9) of a wall (1) or a ceiling including a profile structure (12; 14; 48; 54) having at least one fastening web (21, 22; 49-53; 57, 58) to which the panels (3, 4, 9) are to be fixed, a first profile (17; 55) and a second profile (18; 56) telescopically displaceable relative to the first profile (17; 55) and, in mounted condition, overlapping the first profile (17; 55) for adjusting the length of the profile structure (12; 14; 48; 54). Since the first profile (17; 55) and the second profile (18; 56) have essentially identical cross sections, substantial savings in production costs can be made and logistics can be facilitated, because only one type of profile is needed to assemble the telescopic profile structures (12; 14; 48; 54). During construction of a skeleton (2), the profile structures (12; 14; 48; 54) can be assembled from odd numbers of profiles in any order, without entailing the disadvantage that profiles are left over.

Description

TITLE: Telescopic support structure for supporting panels of a wall or a ceiling

TECHNICAL FIELD

The invention relates to a profile systems for constructing support structures in the form of skeletons supporting panels of a wall, for instance dividing a room into two or more smaller rooms, or for a wall or ceiling panelling to cover an existing wall or ceiling.

BACKGROUND ART

Such profile systems and wall or ceiling construction systems as well as walls or ceilings constructed from components of such systems, are well known from practice, for instance in the form of systems for constructing walls or ceilings having a structure of metal profiles against which panels of plaster board are fastened.

Post profiles of such systems are usually obtainable at lengths of 2.60 to 3 m and edge profiles at lengths of 3.50 m. At such lengths, the posts are sufficiently long to cover the distance between the floor and the ceiling in most rooms after being cut or sawed to the appropriate length. The edge profiles typically have to be cut or sawed to the appropriate length as well. Cutting or sawing the profiles to the required lengths, which lengths first have -to be determined accurately, is very cumbersome.

Although it is possible to clip subsequent sections of the generally U-shaped post profiles together to clamp into each other with an overlap of about 50 cm, the need of cutting the posts, which are provided in excess length, to length entails the drawback that substantial amounts of waste are obtained during construction.

Before being cut to length, the posts are difficult to handle and usually longer than the interior height of the area where the posts are to be positioned making safe storage of the posts difficult if not impossible.

From US Patent 4 397 127, a profile system according to the introductory portion of claim 1, as well as a wall or ceiling construction system according to the introductory portion of claim 14 and a wall or a wall or ceiling panelling according to the introductory portion of claim 15 are known. Because the profiles structures include a first profile and a second profile telescopically displaceable relative to the first profile, before mounting, the profile structures are substantially shorter and can be transported, handled and stored substantially easier. Moreover, the need of cutting the profile structures to the desired lengths is obviated except in special circumstances. Measuring and cutting or sawing is not required, so the associated risk of injury and the need of separately disposing of cut-off material that is left over is avoided and, at the shortest length, the profile structures are easy to handle and transport. However, such profile systems are more costly and logistics are complicated by the need to provide the first and second profiles pairwise.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a solution that allows easy handling and mounting of profile structures as in systems with profile structures composed of telescopically movable profiles, at substantially reduced costs and allowing substantially simplified logistics.

According to a first aspect of the present invention, this problem is solved by providing a profile system of the above-described type in which the first profile and the second profile of the telescopicable profile structure have essentially identical cross-sections.

This allows to make substantial savings in production costs and to facilitate logistics, because only one type of - 3 -

profile is needed to assemble the telescopic profile structures, which profiles are nevertheless, telescopicable when in mounted condition and provided at lengths shorter than the required extended lengths, preferably at lengths slightly longer than half the required extended length.

The invention can also be embodied in a wall or ceiling construction system according to claim 15 and in a wall or a wall or ceiling panelling according to claim 16, which each includes at least one telescopic profile structure of which the first profile and the second profile have essentially identical cross-sections.

A particular advantage of composing the telescopic profile structures of profiles of mutually identical cross- sections is, that during construction of a skeleton, the profile structures can be assembled from odd numbers of profiles in any order, without entailing the disadvantage that each time one profile is left over and has to be used in another profile structure or remains left over.

Particularly advantageous embodiments of the present invention are set forth in the dependent claims.

Further, particular objects, features and advantages of the invention are set forth in detailed description with reference to the drawings.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The invention is described with reference to the presently most preferred embodiments shown in Figs. 1 and 3- 10. Some alternative embodiments are described as well.

In Fig. 4, 6, 7, 8 and 10 portions of a wall are shown in various views. The wall 1 is constituted by a support skeleton 2 and wall panels 3, 4 fastened to that support skeleton 2. The wall 1 is mounted between a floor 5 and a ceiling 6 of a building. In Fig. 10 a second wall 7 meeting the wall 1 at a corner and including a skeleton 8 and panels 9 is shown as well.

The skeleton includes a framework of mutually interconnected profiles. The profiles include end rails 10, 11 along the floor 5 and the ceiling 6, telescopic profile structures 12, 13 forming posts and telescopic profile structures 14 forming beams for receiving installation materials such as electric conduits and wall sockets in wall socket housings 15. Typically end rails are also mounted against existing walls where the wall 1, 2 is to meet that existing wall. The panels 3, 4, 9 are fastened against the posts 12, 13 and the end rails 10, 11 by fasteners 16 (in Figs. 7 and 8 only some of the fasteners are designated by reference numerals) perforating the posts 12, 13 and the end rails 10, 11.

The posts 12, 13 are constituted by first and second profiles 17, 18 and, respectively, 19, 20. The profiles 17,

18 of the posts 12 have identical cross-sections (though, incidental differences due to factors such as manufacturing tolerances and in-use deformations may occur) . The profiles 19, 20 of the posts 20 have different cross-sections, as is best shown in Fig. 9.

In each of the posts, 12, 13 one profile 17, 19 telescopically overlaps the other profile 18, 20 and several ones of the fasteners 16 engage the profiles 12, 13. After the panels 3, 4 have been mounted against the posts 12, 13, the connections between the panels 3, 4 and the posts 12, 13, the connections of the profiles 17-20 to the end rails 10, 11 and the fasteners in the area where the profiles 17,

19 and 18, 20 overlap each keep the posts 12, 13 at the required lengths.

The feature that the posts 12 are formed by profiles 17, 18 having essentially identical cross-sections allows to make substantial savings in production costs and to facilitate logistics, because only one type of profile is needed. The posts 12 are nevertheless, telescopicable when in mounted condition and provided at lengths shorter than the required extended lengths, preferably at lengths slightly longer than half the required extended length, so that the posts are easily manoeuvrable before being installed. During installation and assembly of a skeleton, - 6 -

the posts 12 can be assembled from odd numbers of profiles in any order, without entailing the disadvantage that each time one profile is left over and has to be used in another profile structure or remains left over. The profiles 17-20 of the posts 12, 13 each have fastening webs 21, 22 and, respectively 23-28 to be perforated for fastening the panels 3, 4, 9. Before being fixed by the fasteners 16, the profiles 17, 18 are freely telescopicable . In mounted condition, of the two profiles 17, 18, which are of identical, point-asymmetric cross-section, the second profile 18 is inverted relative to the first profilel7 of that post 12. Thus, a low friction, close fitting guidance between the profiles can be obtained without deformation of the profiles 17, 18. Furthermore, this allows for instance to provide the profiles 17, 18 with an engagement gutter 35 or other engagement structure along one side edge in which the other, opposite side edge of the other profile is engaged (Figs. 1 and 3). The engagement gutter can be provided on a side of the fastening web 22 facing a central web 37 as is shown in Fig. 1, but may also be provided on the opposite side of the free side edge of a fastening web 38, as the gutter 39 shown in Fig. 2.

For obtaining profile structures 12 of which the profiles 17, 18 are smoothly telescopicable without deformation, it is further advantageous if, in the area where the first profile 17 overlaps the second profile 18 the profile structure 12 has a point-symmetric cross- section. This feature is best shown in Fig. 3, but may also be achieved in the form of other designs as is exemplified by Figs. 11 and 12.

Furthermore, the identical profiles sections 17, 18 of the profile structures 12 each have a central portion 37 of which opposite side ends or, more specifically, side edges define a plane 40 (Fig. 1) and adjacent webs 21, 22 (in this example the fastening webs) projecting on opposite sides of that plane 40. Thus identical telescopicable profiles can be - 7 -

obtained in a simple manner. Furthermore, as is best seen in Fig. 7, the posts 12 can be arranged such that the fastening webs 21, 22 on the same side of the wall 1, which webs 21, 22 form part of successive posts 12 all face in the same direction. This substantially facilitates the mounting of isolation plates in the walls, in particular if the plates are of an inflexible material.

Furthermore, before the panels 3, 4 are mounted, from each side of the wall 1, the central webs 37 of the posts 12 are easily accessible with power tools like drills and screw drivers from the side opposite the side towards which the fastening webs 21, 22 on that side of the wall are facing, which facilitates mounting conduits and appliances to the central webs 37 of the posts 12. By providing that the opposite adjacent webs 21, 22 of each profile 17, 18 project in substantially parallel directions, it is assured that the panels 3, 4 on each side of the walll can be mounted to the same plane.

The profiles 17, 18 of the profile structures 12 each have one U-shaped side edge which forms the engagement gutter 35. In the overlapping area of the profile structure 12, the U-shaped side edges of the first and second profile 17, 18 each receive and guide an opposite side edge area 36 of the second and, respectively, first profile 18, 17. Instead of by a U-shaped side edge, the gutter for telescopically receiving an edge of the other profile can be of another shape, such as L-shaped, the angle between the legs of the L being substantially less than 90° and preferably less than 80° or V-shaped, the angle between the legs of the V being preferably 40° to 50°.

The U-shaped side edge areas 35 of the profiles 17, 18 are easily accessible by jaws of a pair of pliers, with which small deformations of the fastening flanges 21, 22 of the first and the second profile 17, 18 can simultaneously be made. In this manner, the length of a profile structure 12 can provisionally be fixed until the profile is fastened to end rails 10, 11 or until panels 3, 4 are fastened to at least one side of the skeleton 2.

Instead of by simultaneous deformation of the profiles, the provisional fixation of the required length of the posts 12 can also be obtained in other manners, for example by inserting temporary fastening means such as a pin in a hole drilled in the overlap.

Since the first profile 17 and the second profile 18 of the profile structures 12 each have a generally Z-shaped cross-section, the profiles are of a relatively simple shape, which is easy to manufacture.

The posts 13 are specifically suitable to form corners in walls and^' have profiles 19, 20 of different cross- sections each including a generally U-shaped portion with fastening flanges 24, 27 and 25, 26 oriented perpendicular to each other, so that wall panels 3, 9 of wall surfaces forming an outside corner can be mounted thereto. The U- shaped portions have central webs 47 opposite the outermost fastening webs 25, 26 thereof which are wider than the respective opposite fastening webs 25, 26. Thus, at the free side of the opposite fastening webs 25, 26 room is left for a fastening web 22 of an adjacent post 12 and the central webs 37 of the profiles 17, 18 of that post 12 are fastened to the extreme opposite fastening webs 23, 28 of the corner post 13. The fastening webs 21, 22, 23, 28 of the posts 12, 13 form an inner corner against which wall panels forming an inner corner can be mounted.

A profile structure having the above functionality of the profile structure formed by the corner post 13 can also be provided in a form in which the telescopicable profiles have mutually identical cross-sections if, as is shown by way of example in Fig. 11, the profile structure 48 has at least five webs 49-53, including two L-shaped pairs of webs 49, 50 and 52, 53 having diagonally opposite corners where the webs 49, 50 and 52, 53 of each of these pairs meet.

Conventionally, the connection between posts and end rails along the ceiling and the floor is made by enclosing end portions of the posts between upstanding flanges of U- shaped end rails. Although this manner of making the connection between the posts and the horizontal end rails can be used in connection with proposed posts 12, 13 as well, it is preferred that the end rails 10, 11 have a width which is smaller than the spacing between opposite fastening webs 21, 22 of the first and second profiles 17, 18, for mounting the fastening webs 21, 22 of the first and second profiles to opposite outside fastening surfaces 41, 42 of the end rails 10, 11. Thus a much more positive alignment of the fastening webs relative to the rails 10, 11 is achieved, because upon fastening of the panels to the skeleton 2, the fastening webs 21, 22 are clamped against the outside fastening surfaces 41, 42 of the end rails 10, 11. This feature is best seen in Figs 4 and 6.

To allow positioning the end portions 21, 22 of the fastening webs against the outside fastening surfaces 41, 42 of the end rails 10, 11, it is preferably provided that central end portions 43 of the profiles 17, 18 are folded or cut away. To this end, the profiles 17, 18 are provided with slits 44 and weakened folding lines 45. As is shown in Fig. 5, the slits 44 have ends that are ended by bridges 46, so that the end portion of the fastening webs 21, 22 are securely supported and formation of "ears" at such end portions of the fastening webs 21, 22 is counteracted. Just before mounting the profiles 17, 18 to the end rails 10, 11, the bridges can easily be cut away, so that the end portions 43 of the central webs 37 can be folded away to create room for the rails 10, 11 between the fastening webs 21, 22. It is also possible to provide slits 44 which are wide enough to receive the webs of the end rails 10, 11, so that the end portions 43 of the central webs 37 do not need to be bent or cut away.

Instead of as a hollow wall, as shown, the same profile system and the same wall or ceiling construction system can also be used for constructing a single layered wall or ceiling which is for example to be installed in the - 10 -

form of a cover of an existing wall or ceiling which is in a bad condition.

The length of the posts 12, 13 can easily be adapted to the height of the room during mounting of the posts 12, 13 by extending the freely telescopicable upper profile 17, 19 from the lower profile 18 respectively 20 until it abuts the end rail 11 mounted to the ceiling 6. Preferably some play is left between the end rails 11 and the posts 12, 13 to allow for deformations of the building and the posts 12, 13. The lengths of the posts 12, 13 can very easily be adapted manually to any required length within a very large range, by holding the first profile in one hand and the second profile in the other hand and longitudinally displacing the profiles relative to each other until the required extension is reached. Generally, the only resistance that has to be overcome is some friction between the profiles 17, 19 and 18, 20 that may fit loosely or tightly, and the weight of the upper profile 17, 19, which has to be urged towards the ceiling. Measuring and cutting or sawing is not required, so the associated risk of injury is avoided.

If a wall or ceiling construction has become redundant, the telescopic posts 12, 13 can be used again as a component of a wall to be constructed in another room after the panels 2, 3 have been dismounted therefrom. This other room may even have a larger height than the room in which the respective posts 12, 13 were installed previously, because the posts 10 can be extended to larger lengths than the lengths at which these posts 10 were fixed in the previous room. In connection with this, it is particularly advantageous that the posts 12 consist of profiles 17, 18 of identical cross-section, because this allows to combine the profiles 17, 18 in any order.

The posts 12, 13 are preferably stored and transported at the shortest length so that handling and transport is substantially facilitated and little storage space is required to keep stocks of the posts 12, 13. To avoid that -li¬

the posts 17 completely overlap the profiles 18, which would make extending the profiles 17 more difficult, the posts 17 are provided with a projection 29 towards the side of the other profile 18 adjacent an end of the profile 17 projecting from the other profile 18. The projection is formed by a lip, but may also be in the form of another deformation or in the form of a button or the like fastened to the profile 17. In addition, to facilitate extending the profile structures, one profile 17, 19 is preferably at least 5 to 10 cm longer than the other profile 18, 20, so that a complete overlap between telescopicable profiles cannot occur.

Since the profiles 17, 19 and 18, 20 are freely displaceable relative to each other in longitudinal direction, relative movement of the profiles is very smooth, so that the adjustment of the length of the profile structure can be carried out with particular ease. After the posts 12, 13 have been extended to the required length, the fixation of the required length is obtained as described above.

The more the lengths of the first and the second profiles 17, 19 and 18, 20 are equal, the larger the difference between the lengths of the posts 12, 13 in compressed condition and in maximally extended condition is. Therefore, the lengths of the first profile 17, 19 and the second profile 18, 20 preferably relate to each other at a ratio between 2:1 and 1:2 and even more preferably at a ratio between 1.5:1 and 1:1.5. If the profiles 17, 19 and 18, 20 are of about the same length, taking into account a slight difference as discussed above, for example a post 12, 13 of a length of about 1.60 m in compressed condition which can be extended to lengths of up to about 2,60 m while maintaining sufficient overlap to obtain a stable structure. Posts of 1.50 m can easily be transported in most passenger cars, so that the system can easily be employed by private persons constructing a wall or a ceiling as a do-it-yourself project . - 12 -

The profiles 17-20 are made of metal and, dependent on the requirements, have a wall thickness of 0.3-1.0 mm and preferably of 0.4-0.7 mm. This allows easy perforation of the fastening webs 21-28 at any desired spot and also in the area where the profiles 17-20 overlap. Thin material of the profiles 17-20 further provides the advantage that the step at the transition of the first profile 17, 19 to the second profile 18, 20 is accordingly small, which in turn is advantageous for the planeness of the wall or ceiling. The metal is preferably steel, which allows a small wall thickness at a relatively important strength.

However, the profiles can also be made of other materials, such as plastics which may be fibre-reinforced or wood. If relatively thick walled materials are used, it may be advantageous to provide that fastening flanges of the first and the second profile are provided in positions staggered in a direction transverse to the profiles and parallel to the plane of the panels.

To further facilitate the construction of walls, the profiles 17-20 are provided with support structures in the form of perforations 30 (see Fig. 8, not shown in the other Figs.) for supporting the horizontal beams 14 of the support skeleton at predetermined distances from an end of the respective profile 17-20. The beams 14 are provided with connection lips 31, which can be inserted in the perforations 30 in the required positions. The profiles 17- 20 are further provided with perforations 32 for passing conduits for electricity, gas or water through the posts 12, 13. The horizontal beams are of a telescopic design as well and are each formed by a C-shaped profile 33, 34. Housings such as the housing 15 for wall sockets or the like can easily be mounted against flanges at the open side of the C-shaped profiles 33, 34. In addition, the closed sides of the C-shaped profiles are preferably provided with one or more openings for receiving a wall socket housing and for the passage of conduits. The beams 14 facilitate safe and - 13 -

well-supported mounting of wall sockets and other installation parts behind the panels 3, 4, 9. In combination with the predetermined height of the perforations 30 from a free projecting end of the profiles 17-20, it is further assured that all wall sockets mounted in the beams 14 are mounted at the same height.

In Fig. 12, an example of a profile structure 54 is shown, which may be used to form posts or horizontal beams. In assembled condition, the profile structure 54 forms a closed boxed and can simultaneously serve for guiding conduits of different types, such as electric wiring. The profile structure 54 has ribbed fastening flanges 56, 57. This increases the stiffness of the fastening flanges at a given thickness and, facilitates perforation of these flanges, in particular when by self drilling screws are used. If the increased stiffness of the ribbed flanges 56, 57 is used reduce the wall thickness while retaining a given minimum stiffness, perforating the fastening flanges 56, 57 is even further facilitated. The panels 3, 4, 9 can made of any type of suitable material, such as multiply-wood or metal. Most preferably, however, the panels 2, 3 are made of a light-weight material, such as plaster board.
