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.
  • WO 93/04256 describes a coupling for compound profile members for doors or windows.
  • Several keys are spaced along the profile, having opposite flanges, which are connected to the profiles by rotation.
  • Said disc-shaped flange has a modified disc-shaped form with elastic interference protrusions on two orthogonal axes respectively coinciding one or the other with the plane passing on the longitudinal axis of said key-shaped flange.
  • 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.
  • 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.
  • 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°.
  • 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.
  • 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.
  • the said check means consists of a rib on the said first section.
  • 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.
  • the lower plate prevents the accidental extraction of the connecting element from the channel.
  • 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.
  • 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 joining pin 5.
  • the pin 5 is integral with a lever 6.
  • the lever 6 has a peg 7 projecting below which acts as a limit stop.
  • the lever 6 also has an operating tab 8 projecting above.
  • the plates 3 and 4 have a substantially rectangular shape in plan with two opposite corners rounded.
  • the plates 3 and 4 have longitudinal central axes 103 and 104 which are not in the same plane and are inclined at an angle of approximately 30° to each other. In other words, the plates 3 and 4 are out of alignment, being rotated with respect to each other through a predetermined angle about a longitudinal central axis of the pin 5.
  • the angle of rotation between the plates 3 and 4 may range from approximately 10° to approximately 50°.
  • the lever 6 is inclined at an angle of approximately 45° to the plate 4.
  • a longitudinal central axis 106 of the lever 6 forms the said angle with the longitudinal central axis 104 of the plate 4.
  • the angle of inclination of the lever 6 with respect to the plate 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 facing block 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, an outer face 13 and two lateral faces 14 and 15.
  • the inner face 12 has a longitudinal channel 16 having inwardly projecting edges 116 and 216.
  • the channel 16 is capable of housing the lower plate 3 of the connecting element 1, as will be explained subsequently.
  • the face 12 also has a longitudinal rib 18 which acts as a check for the peg 7 of the lever 6.
  • the outer face 13 has a stop fin 19 having a C-shaped seat 20 for a sealing gasket which is not shown.
  • the lateral face 14 has a C-shaped seat 21 capable of housing a glazing retention section which is not shown.
  • the lateral face 15 has a C-shaped seat 22 for another sealing gasket, which again is not shown, and a projecting fin 23 having a substantially Z-shaped cross-section.
  • the block 30 has a longitudinal channel 31 and two undercuts 32 and 33 (Fig. 4).
  • the channel 31 is capable of housing the upper plate 4 of the connecting element 1 (Fig. 5), as will be explained subsequently.
  • the fin 23 of the section 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 the section 10.
  • the lower plate 3 of the connecting element 1 is inserted into the channel 16 in the longitudinal position (condition a)).
  • the lever 6 is then rotated in the anti-clockwise direction, as shown by the arrow 25, until it brings the peg 7 to bear on the rib 18 (condition b)).
  • the lower plate 3 assumes a first position inclined at approximately 40° in the anti-clockwise direction to the longitudinal axis of the channel 16, and two of its corners are positioned under the edges 116 and 216 of the channel 16. In this way, the connecting element 1 remains locked to the channel and cannot be accidentally displaced.
  • the upper plate 4 in turn, assumes a longitudinal position, aligned with the channel 16 and, therefore, also with the channel 31 of the block 30 (Fig. 4).
  • the block 30 can be mounted on the connecting element by fitting the plate 4 into its channel 31.
  • the lever 6 is then rotated through 90° in the anti-clockwise direction, as shown by the arrow 26, until the peg 7 is again made to bear against the rib 18 (condition c)).
  • the lower plate 3 assumes a second position inclined at approximately 40° in the clockwise direction to the longitudinal axis of the channel 16 in which its other two corners are positioned under the edges 116 and 216 of the channel 16, while the upper plate 4 assumes a transverse position and is wedged into the channel 31 (Figs. 3 and 5) to join the block 30 and the section 10.
  • Numerous connecting elements 1 are mounted in the channel 16 at predetermined distances, according to the procedure described above. In this way, the block 30 is fixed securely to the section 10.
  • the connecting element 1 can be displaced easily from condition c) to condition b) by a simple rotation of the lever 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 the channel 16. This makes it unnecessary to re-adjust their spacing in the channel 16.
