Definitions
- the present invention relates to a connecting element for a composite section and a composite section comprising the said connecting element.
- a connecting element for a composite section and a composite section comprising the said connecting element.
- it relates to a metal-wood composite element for window and door frames.
- Window and door frames formed from metal-wood composite sections are increasingly widely used both for aesthetic reasons and because of their properties of thermal and acoustic insulation.
- a composite section comprises an outer metal section, an inner wooden facing element and one or more elements for connection between the section and the facing element.
- a connecting element consisting of a plastic strip provided with projections and tabs for fastening to the metal section and to the wooden facing element is used.
- the strip acts as a connection between the section and the wooden facing element and provides a seal and complete thermal insulation between them.
- the metal section and the wooden facing element are connected by a plurality of connecting elements consisting of shaped plastic blocks capable of being engaged in channels in the section and in the facing element.
- Rubber sealing gaskets are interposed between the section and the facing element, and these gaskets, together with the connecting blocks, also provide a thermally insulating action.
- the shaped plastic blocks are basically of two types.
- the first type consists of two substantially rectangular plates, one lower and one upper, having mirror symmetry and in alignment, joined by a solid pin which is integral with a lever.
- the lever is disposed orthogonally with respect to the plates.
- a second type consists of two plates of substantially oval shape having mirror symmetry and in alignment with each other, made integral by means of a pin provided with a through hole.
- the blocks are arranged in the channel of the metal section at predetermined distances from each other.
- Each block is positioned in the channel with the lower and upper plates disposed longitudinally and the lever disposed transversely.
- the wooden facing element is then mounted on the blocks, the upper plates of the blocks being inserted into its channel.
- the lever of each block is rotated through 90° so that it is disposed longitudinally with respect to the channels of the metal section and the facing element.
- the upper and lower plates of the block are disposed transversely in the two channels and the metal section and the facing element are fixed to each other.
- the sealing gaskets are then inserted between them.
- each block is positioned in the channel of the wooden facing element with the plates disposed longitudinally and is fixed to the facing element by means of a screw which passes into its perforated pin.
- the metal section is mounted on the upper plates of the blocks.
- Each block is then rotated through 90° so that its plates are disposed transversely in the two channels of the metal section and of the wooden facing element. This procedure is carried out by means of a special spanner which is inserted in the gap between the metal section and the facing element and which can grip the pin integral with the plates and turn it. The operation must be repeated for all the blocks, so that the wooden facing element and the metal section are fixed to each other.
- connecting blocks of the two types described above has a number of disadvantages, both during the assembly of a composite section and during the dismantling of the section, for example in order to replace a damaged wooden facing element.
- the blocks of the first type remain loose in the channel of the metal section when they are disposed longitudinally, and it is possible for them to be accidentally displaced from the positions in which they were placed, when the wooden facing element is placed against them.
- the spacing between the blocks may therefore be changed in a random way.
- the operation of rotating the blocks is carried out by inserting a tool with a hooked point into the gap between the metal section and the facing element in such a way as to grip the lever disposed longitudinally with respect to the channels.
- the lever is made to rotate until it is disposed transversely with respect to the channels, so that the plates of the block are disposed longitudinally with respect to the channels.
- This operation must be repeated for all the blocks of the composite section. After this it is possible to remove the damaged facing element.
- the procedure entails a series of laborious operations which take up a great deal of time and push up the costs of the replacement of the wooden facing element.

Abstract
Description
- The present invention relates to a connecting element for a composite section and a composite section comprising the said connecting element. Preferably, it relates to a metal-wood composite element for window and door frames.
- Window and door frames formed from metal-wood composite sections are increasingly widely used both for aesthetic reasons and because of their properties of thermal and acoustic insulation.
- Generally, a composite section comprises an outer metal section, an inner wooden facing element and one or more elements for connection between the section and the facing element.
- In some composite sections, such as those described in EP-0 695 847, filed in the name of the present applicant, a connecting element consisting of a plastic strip provided with projections and tabs for fastening to the metal section and to the wooden facing element is used. The strip acts as a connection between the section and the wooden facing element and provides a seal and complete thermal insulation between them.
- In the aforesaid composite sections, it is rather difficult to remove the wooden facing element if it becomes damaged and has to be replaced, owing to the fact that the strip is fixed securely to the section and to the facing element.
- In other composite sections, the metal section and the wooden facing element are connected by a plurality of connecting elements consisting of shaped plastic blocks capable of being engaged in channels in the section and in the facing element. Rubber sealing gaskets are interposed between the section and the facing element, and these gaskets, together with the connecting blocks, also provide a thermally insulating action.
- The shaped plastic blocks are basically of two types. The first type consists of two substantially rectangular plates, one lower and one upper, having mirror symmetry and in alignment, joined by a solid pin which is integral with a lever. The lever is disposed orthogonally with respect to the plates. A second type consists of two plates of substantially oval shape having mirror symmetry and in alignment with each other, made integral by means of a pin provided with a through hole.
- To assemble a composite section by means of the lever blocks of the first type, the blocks are arranged in the channel of the metal section at predetermined distances from each other. Each block is positioned in the channel with the lower and upper plates disposed longitudinally and the lever disposed transversely. The wooden facing element is then mounted on the blocks, the upper plates of the blocks being inserted into its channel. At this point, the lever of each block is rotated through 90° so that it is disposed longitudinally with respect to the channels of the metal section and the facing element. When this is done, the upper and lower plates of the block are disposed transversely in the two channels and the metal section and the facing element are fixed to each other. The sealing gaskets are then inserted between them.
- The composite sections using blocks of the second type are assembled in a similar way. Each block is positioned in the channel of the wooden facing element with the plates disposed longitudinally and is fixed to the facing element by means of a screw which passes into its perforated pin. After all the blocks have been mounted at a predetermined distance from each other, the metal section is mounted on the upper plates of the blocks. Each block is then rotated through 90° so that its plates are disposed transversely in the two channels of the metal section and of the wooden facing element. This procedure is carried out by means of a special spanner which is inserted in the gap between the metal section and the facing element and which can grip the pin integral with the plates and turn it. The operation must be repeated for all the blocks, so that the wooden facing element and the metal section are fixed to each other.
- The use of connecting blocks of the two types described above has a number of disadvantages, both during the assembly of a composite section and during the dismantling of the section, for example in order to replace a damaged wooden facing element.
- During assembly, the blocks of the first type remain loose in the channel of the metal section when they are disposed longitudinally, and it is possible for them to be accidentally displaced from the positions in which they were placed, when the wooden facing element is placed against them. The spacing between the blocks may therefore be changed in a random way.
- This disadvantage is not present with the blocks of the second type which are fixed in the channel of the wooden facing element by means of screws. However, a correct spacing between the blocks is achieved by a series of operations which increase the assembly time.
- When a composite section comprising connecting blocks of one or the other type is dismantled, it is necessary to remove the sealing gaskets and then to rotate the blocks through 90° in the opposite direction to the direction of assembly. In this way, the plates of the blocks are disposed longitudinally in the channels of the metal section and of the facing element, and it is possible to separate the facing element from the metal section.
- In the case of sections provided with blocks of the first type, the operation of rotating the blocks is carried out by inserting a tool with a hooked point into the gap between the metal section and the facing element in such a way as to grip the lever disposed longitudinally with respect to the channels. When force is applied with the tool, the lever is made to rotate until it is disposed transversely with respect to the channels, so that the plates of the block are disposed longitudinally with respect to the channels. This operation must be repeated for all the blocks of the composite section. After this it is possible to remove the damaged facing element. The procedure entails a series of laborious operations which take up a great deal of time and push up the costs of the replacement of the wooden facing element.
- Similar problems are encountered in the dismantling of composite sections provided with connecting blocks of the second type. In this case, in order to turn them 90° in the opposite direction to that of assembly, use is made of the same spanner that was used during assembly. The manipulation of the spanner in the gap between the facing element and the metal section is rather difficult, and it has to be repeated for all the blocks before the wooden facing element can be removed.
- The objects of the present invention are a connecting element for a composite section and a composite section comprising the said connecting element which are free of the disadvantages of those described above.
- A first aspect of the invention is a connecting element for a composite section comprising a first section having a first channel and a second section having a second channel, the said connecting element comprising a block consisting of two plates, one lower and one upper, each having a central axis, joined by a joining element, and a lever integral with the said joining element, the said lower plate being capable of being housed in the said first channel of the said first section and the said upper plate being capable of being housed in the said second channel of the said second section, characterized in that the said plates have central axes which are not in the same plane and are inclined at a predetermined angle to each other, the said lower plate assuming a first inclined position of engagement and a second inclined position of engagement with the said first channel to retain the said block at a predetermined point of the said first channel, while the said upper plate assumes a longitudinal position and a transverse position respectively with respect to the said second channel to fix, in the said transverse position, the said second section to the said first section.
- According to a preferred embodiment of the invention, the said lever has a stop element which engages with a check means of the said first section to assume a first and a second limit position in which the said lower plate assumes the said first inclined position and the said second inclined position respectively, while the said upper plate assumes the said longitudinal position and the said transverse position respectively.
- According to another preferred embodiment of the invention, the said plates are rotated with respect to the other through an angle ranging from approximately 10° to approximately 50°, and preferably through an angle of approximately 30°.
- According to a further preferred embodiment of the invention, the said lever is inclined with respect to the said upper plate at an angle ranging from approximately 30° to approximately 60°, and preferably at an angle of approximately 45°.
- A second aspect of the invention consists of a composite section comprising a first section having a first channel, a second section having a second channel and at least one connecting element, the said connecting element comprising a block consisting of two plates, one lower and one upper, each having a central axis, joined by a joining element, and a lever integral with the said joining element, the said lower plate being capable of being housed in the said first channel of the first section and the said upper plate being capable of being housed in the said second channel of the said second section, characterized in that the said plates have central axes which are not in the same plane and are inclined at a predetermined angle to each other, the said lower plate assuming a first inclined position of engagement and a second inclined position of engagement with the said first channel to retain the said block at a predetermined point of the said first channel, while the said upper plate assumes a longitudinal position and a transverse position respectively with respect to the said second channel to fix, in the said transverse position, the said second section to the said first section.
- According to a preferred embodiment, a check means is associated with the said first channel of the said first section and the said lever is provided with a stop element which engages with the said check means to assume a first and a second limit position in which the said lower plate assumes the said first inclined position and the said second inclined position respectively, while the said upper plate assumes the said longitudinal position and the said transverse position respectively.
- Preferably, the said check means consists of a rib on the said first section.
- According to another preferred embodiment, the said first section comprises a tubular body having an inner face, an outer face and two lateral faces, the said inner face having the said first channel and the said check rib.
- The connecting element according to the invention has numerous advantages.
- The block with the two plates can be placed in the channel of a metal section in a very precise position, without the possibility of its accidental displacement. This is due to the fact that, when the upper plate is disposed longitudinally with respect to the channel, the lower plate, being out of alignment and rotated with respect to the upper plate, assumes an inclined position with respect to the longitudinal axis of the channel which causes it to interact partially with the edges of the channel. Thus the lower plate prevents the accidental extraction of the connecting element from the channel. Additionally, the stop element of the lever bears on the check of the metal section which acts as the limit stop, and prevents accidental sliding of the connecting element along the channel.
- Another advantage of the connecting element according to the invention consists in the inclined disposition of the lever with respect to the upper plate, which makes the lever easily accessible from the outside both when locking and unlocking the connecting element.
- Characteristics and advantages of the invention will now be explained with reference to an embodiment illustrated by way of non-restrictive example in the attached drawings, in which
- Figs. 1 and 2 are views from above and below, respectively, of a connecting element for composite sections, made according to the invention;
- Fig. 3 is a view from above of a metal section in which the connecting element shown in Figs. 1 and 2 is filled;
- Fig. 4 is a front view of the metal section shown in Fig. 3, of the connecting element shown in Figs. 1 and 2, and of a wooden facing element;
- Fig. 5 is a front view of an assembled composite section, consisting of the metal section, the connecting element and the wooden facing element shown in Fig. 4.
-
- Figs. 1 and 2 show a connecting element 1 comprising a
block 2 consisting of two plates, 3 and 4, being the lower and upper plates respectively, joined by a joiningpin 5. Thepin 5 is integral with alever 6. Thelever 6 has apeg 7 projecting below which acts as a limit stop. Thelever 6 also has anoperating tab 8 projecting above. - The
plates plates central axes plates pin 5. The angle of rotation between theplates - The
lever 6 is inclined at an angle of approximately 45° to theplate 4. In other words, a longitudinalcentral axis 106 of thelever 6 forms the said angle with the longitudinalcentral axis 104 of theplate 4. The angle of inclination of thelever 6 with respect to theplate 4 may range from approximately 30° to approximately 60°. - The connecting element 1 is used to assemble in a dismountable way a composite section 100 (Fig. 5) consisting of an
aluminium section 10 and a wooden facingblock 30. The composite metal-wood section 100 is suitable for the construction of a frame such as a window or door frame (not shown). - The aluminium section 10 (Figs. 3-5) comprises a tubular body 11 having a substantially rectangular cross-section. The tubular body 11 has an
inner face 12, anouter face 13 and two lateral faces 14 and 15. Theinner face 12 has alongitudinal channel 16 having inwardly projectingedges channel 16 is capable of housing thelower plate 3 of the connecting element 1, as will be explained subsequently. Theface 12 also has alongitudinal rib 18 which acts as a check for thepeg 7 of thelever 6. Theouter face 13 has astop fin 19 having a C-shapedseat 20 for a sealing gasket which is not shown. Thelateral face 14 has a C-shapedseat 21 capable of housing a glazing retention section which is not shown. Thelateral face 15 has a C-shapedseat 22 for another sealing gasket, which again is not shown, and a projectingfin 23 having a substantially Z-shaped cross-section. - The
block 30 has alongitudinal channel 31 and twoundercuts 32 and 33 (Fig. 4). Thechannel 31 is capable of housing theupper plate 4 of the connecting element 1 (Fig. 5), as will be explained subsequently. Thefin 23 of thesection 10 comes to bear on the undercut 32. - Fig. 3 shows the connecting element 1 in the positions assumed in the phases of assembly in the
channel 16 of thesection 10. Initially, thelower plate 3 of the connecting element 1 is inserted into thechannel 16 in the longitudinal position (condition a)). Thelever 6 is then rotated in the anti-clockwise direction, as shown by thearrow 25, until it brings thepeg 7 to bear on the rib 18 (condition b)). In this condition, thelower plate 3 assumes a first position inclined at approximately 40° in the anti-clockwise direction to the longitudinal axis of thechannel 16, and two of its corners are positioned under theedges channel 16. In this way, the connecting element 1 remains locked to the channel and cannot be accidentally displaced. Theupper plate 4, in turn, assumes a longitudinal position, aligned with thechannel 16 and, therefore, also with thechannel 31 of the block 30 (Fig. 4). At this point, theblock 30 can be mounted on the connecting element by filling theplate 4 into itschannel 31. Thelever 6 is then rotated through 90° in the anti-clockwise direction, as shown by the arrow 26, until thepeg 7 is again made to bear against the rib 18 (condition c)). In this condition, thelower plate 3 assumes a second position inclined at approximately 40° in the clockwise direction to the longitudinal axis of thechannel 16 in which its other two corners are positioned under theedges channel 16, while theupper plate 4 assumes a transverse position and is wedged into the channel 31 (Figs. 3 and 5) to join theblock 30 and thesection 10. Numerous connecting elements 1 are mounted in thechannel 16 at predetermined distances, according to the procedure described above. In this way, theblock 30 is fixed securely to thesection 10. - If it is necessary to remove the
block 30, the connecting element 1 can be displaced easily from condition c) to condition b) by a simple rotation of thelever 6 in the opposite direction to that of assembly. It is worth noting that the rotation of the connecting elements 1 does not alter their longitudinal positioning in thechannel 16. This makes it unnecessary to re-adjust their spacing in thechannel 16.
