• support wings 167 It is possible to increase the length of support wings 167, by adding to such wings one or more complementary profiles 4, shown in figures 3 and 26, in a way similar to that shown in figures 6-9 and 26, but not shown in figure 36.
• the additional section can comprise a clamping portion consisting of a fixed wall 176 of additional section 160, inner to housing, and a movable jaw member 180 (figure 37), operated by pushing members 169 (figure 38).
• the movable jaw member 180 has an outer face 181 and an inner face 182.
• pushing members 169 are operated by a gear system having perpendicular axes, for example a nut-worm screw system 190, mounted in the recess defined by surfaces 165, 166 and 163, which can be operated from the outside rotating a screw 174 (figure 39) .
• the sheet in particular of glass, is insulated from the additional section by resilient seals 171, 172 and 173.
• Figure 39 shows a perspective view of figure 38.
• an exemplary assembling step is shown of a glass sheet 138 using section 150 for fixed sheets already described in figure 31, both for assembling the lower edge of sheet 138 on a ground surface 210 and the upper edge on a ceiling surface 220.
• sheet 138 can be mounted with additional section 160 hidden in the ground or in the ceiling.
• section 150 and additional section 160 can be mounted on all the sides of sheet 138.
• arranging the additional section 160 on all the sides the whole frame of the closure panel 138 remains completely hidden when the assembling steps are completed.
• the additional section 160 allows to assemble safely boards with regular geometric shape, or shaped with irregular shape, protruding from a ground surface, from a wall, from a ceiling surface where the assembling device remains completely hidden, with ideal aesthetic effect.
• Figure 42 shows a main section 200 according to the invention where the face from the side of the aperture 31 is plane, without shoulder.
• This particular conformation allows use this section 200 for making a crosspiece of the frame structure for a door 60' (fig 45) , having an axis of rotation 60' ' not coincident with an edge of the door 60' .
• Such plane shape is required because it works both for push- type and for pull-type engagements at the same time; in fact a portion of this section 200 should work for a pull-type door and another for a push-type door, since a side edge of the door has a push-type engagement, and the opposite edge has a pull-type engagement.
• such a section can be used for defining an aperture, not shown in the figure, on a wall or on a ground or on a ceiling, creating a frame portion on one or several sides of the aperture.
• FIGS 43 and 44 examples are shown of a section for a pull-type door 2 and a push-type door according to the invention 1 used as uprights opposite to the frame.
• Such profiles 43 and 44 repeat the shape and the features of the respective profiles 2 and 1 of figures 2 and 1 with the difference that the enlarged portion 32 does not comprise recesses 24 (figure 1 and 2) .
• the foregoing description of a specific embodiment will so fully reveal the invention according to the conceptual point of view, so that others, by applying current knowledge, will be able to modify and/or adapt for various applications such an embodiment without further research and without parting from the invention, and it is therefore to be understood that such adaptations and modifications will have to be considered as equivalent to the specific embodiment.
• the means and the materials to realise the different functions described herein could have a different nature without, for this reason, departing from the field of the invention. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.
