Sealing strip. 15 is secured to section 3 at only one center point as it

is provided with a © gap 71 through which it is mounted on the bent downwardly extending portion 13 and on the edge 14. The sealing strip 15 serves as a tight closure and is provided with a wall 17 inclined to the slot 34, which facilitates the discharge of penetrated water. The inner socket 66 of the tubular housing is used to fit a clamp / not shown / to attach sections 3 arranged in a right angle. The tubular housing 6 also comprises an inner wall 16 having two ribs. 18, inclined towards the wall itself, forming a channel with a profile of the swallow tail 19, and provided with two deformable teeth. 20 next to the rib 18.

The fiberglass tape 5, also shown in FIGS. 4 and 8, has a ribbon-like projection on one side. swallow tail 21 and two lateral edges provided with recesses 24, separated from the central lane 21 by two grooves 22. The ribbon 5 on the other side has two. jagged or cut dowel elements 25 and a support side 26 protruding laterally, the function of which will be shown below. Some walls of the strip 5 are cut for better grip to the wooden block 4.

At this point, the wooden block 4 is mounted. by pressing the toothed dowel elements 25 of the strip 5 so that the toothed dowel elements 25 are pressurized into the longitudinal slots 30, while at the same time the support page 26 is inserted into; sidewise incised bed 31 on the same wooden block 4.

In this way, the metal section 3 and the wooden block 4 join together tightly in a direction perpendicular to the walls 7 and 16, while the presence of gaps between the strip 21 and the channel 19 and between the ribs 18 and the channels 22 allow for relative displacements of the section 2 and block 4 in the direction parallel to the walls 7 and 16, which compensates for the different thermal extensions obtained for the outer *

aluminum section 2 and indoor wood block 4.

The support page 26 of the strip 5 serves as a thermal insulation element between the block. 4 and a steel plate of the locking mechanism 33 of the closure 60 (hinges and crematory bolt) of the movable wing.

Thus, the strip 5 serves as a means of connecting section 3 to the block and as a thermal insulator, which completely isolates the wooden block 4 from the section 3 and from the plate of the locking mechanism 33, avoiding condensation,. which would cause the wooden block to rot. *

The composite section 2 comprises, with an outer aluminum supporting section 35, two inner lining members formed by two blocks of wood 4 and 40 at right angles, the second of which serves as an element for. supporting the glass, an interconnecting piece shaped like a strip 5 of plastic material, such as fiberglass reinforced PVC, and interconnecting pieces shaped like nylon fasteners 50. The straps 5 and the fasteners 50 are used to secure the wooden blocks 4 to the aluminum section 35 and to the thermal insulation of the blocks 4 of the section 35.

Aluminum Section 35. also shown in Figure 3 'is produced by extrusion and contains a tubular body 36 with a substantially polygonal cross-section. The tubular body 36 in the following order comprises an outer wall 37 having a substantially trapezoidal shape, projecting outwards and a lateral bearing peGbro 38 provided with a double U-shaped socket 39 for a sealing strip and provided with a bed 32 for bracket / not shown / for reinforcement and alignment of ribs 38 of section 35 at right angles. There is an opening 70 at the base of the rib 38 for condensate removal and for window glass ventilation (not shown). Wall 37 is also provided with an extension; 41 having a curved end, - with which the rib 8 of the constituent section 1 comes into contact. The extension 41 serves as a counter means: it prevents any permeable water from flowing through section 35 and forces it to flow to the discharge slot 34. The tubular housing 36 also comprises a first side wall 42 provided with a (/-shaped socket 44, in which it is inserted with a clamp formed as an omega part 45 of plastic, such as impact-resistant PVC (also shown in Figures 6 and 9) having a nozzle 46. The part 45 is used to thermally insulate the aluminum section 35 of the steel bar 55 of the device 60 to close the movable cover The wall 42 is also provided with a support tongue 57, with which the sealing strip 15 enters in. contact. The tubular housing 36 comprises a second side wall 47 provided with openings 48, into which each of them is inserted by a gripping deformable retaining tooth. 49 of the fastening element 50. The tubular housing 36 also has an inner wall 511 provided with two sloping ribs 52 forming a V-shaped groove 53 ' and having two deformable teeth; 54 next to the ribs 52. Internal socket 56 of. the tubular. housing 36 is used to fit a connecting bracket, not shown. sections 35 arranged under. right angle .

Each fastener 50, also shown in Figures 5 and 10, is formed of a nylon block provided with a notched end 58 and provided, on the opposite side of one of the deformable teeth 49, with a serrated or cut off white element 59 allowing it to be inserted by pressing in. the longitudinal channel 62 of the window 40 held on the glass.

The function of. the fasteners 50 may be made of plastic tape; material having the same shape as the fastener 50. fitted with a toothed dowel member 59 and a series of deformable clamping teeth 49.

The wooden block 40 has the same shape and dimensions as those of block 4.

The assembly section 2 is mounted by attaching the metal section 35 to the wooden block 4 by means of the tape 5, with the operating system described.in the assembly of the assembly section 1. The fastening elements 50 are secured to the metal section 35 by inserting the engagement teeth 49 into: the holes 48 on the wall 47. The block 40 is assembled by pressing the toothed dowel elements 59 of the fasteners 50 so that the dowel elements 59 are pressurized into the longitudinal groove 30 of the same block 40, while the support side 26 of the strip 5 remains disposed between the blocks 4 and 40. The rod 55 of the device 60 is inserted into the bed 44 after inserting the omega-shaped portion 45, which is in contact with the belt 5 with the nozzle. 46. Sealing strip 65 is inserted into the groove 28 to serve as a seal between ^. ^

below sections 1 and 2.

Thus: in such a way that the metal joints together with the walls 42 of section 35 and blocks 4 and 40 together respectively; indirectly (perpendicular to the wall and 47 'while the presence of gaps between the protruding strip 21. and the groove 53 and between the ribs 52 and grooves 22 allows relative displacements between section 35 and block 4 in a direction parallel to the groove 51 to compensate the difference in the thermal expansion of the aluminum section 35 and the wooden block 4.

The metal section 35 is thermally insulated from the wooden blocks 4 and 40 by means of the strip 5 and the blocks 50 and. The glass is thus thermally insulated from the rod 55 of the device 60 by means of the omega-shaped part 45 of plastic; material, while the support page 26 of the strip 5 serves as a sealing strip between blocks 4 and 40.

'The metal section 35 is completely thermally insulated from the blocks

40 and from the bar. 55 by means of the strap 5, the fasteners 50 and the omega-shaped part 45 due to the fact that the strap and fasteners 50 are disposed below. makes angles and remains in contact at the end 27 and the notched end 58, and the part. 45 remains in contact with: the tape 5 by means of the nozzle 46.

Thus the section 35 remains completely isolated from the blocks 4 and the rod 55 so that _; that the formation of condensate, which would cause the wood blocks to rot, and the increase of galvanic currents between section 35 and rod 55 leading to oxidation are avoided.
