  • An illustrative example of a preferred embodiment of the sectioned cover frame is shown in Figures 8a and 8b .

  • the locking hole 58 and the release hole 59 are located between the two wings 551, extending in a direction parallel to them.
  • the passage of the shank 508 between the locking hole 58 and the release hole 59 then occurs by axially translating the locking element 55; in other words by, by translating the locking element 55 partially housed in the cavity 400, for example translating along an upright axis X-X, if engaged with the upright element 41, or by translating it along a transversal axis Y-Y, if engaged with the transversal element 42.
  • the locking hole 58 and the release hole 59 are mutually divided by a retention septum 56, or two retention wings or protuberances, suitable, with its transversal presence, to impede the passage of the shank 508 between the locking hole 58 and the release hole 59.
  • the retention septum 56 makes necessary a predefined action on the locking element 5 to obtain its breaking or bending, and then to allow the disassembly of these from the weight-bearing frame 3; in this way the transparent element 2 is securely locked on the weight-bearing frame 3.
  • the locking element 5 has a bead 581, in the vicinity of the locking hole 58, engageable by the head of the screw 508; preferably said cord 581 has a greater height than the portion of the locking element 5 surrounding the release hole 59.

  • the cover frame having structural and aesthetic characteristics different from the cover frames of the currently known sashes.
  • the cover frame, mounted on the sash has an aesthetic impact totally different from currently known sashes.
  • the cover frame is suitable to solve a series of technical issues related to the engagement between upright elements and transversal elements.
  • the two elements are not mutually engaged in such a way that the two engagement surfaces are perfectly facing, due to imprecise machining or assembly operations, between the two components there is a particularly visible slot. Since, in the sash covered by this invention, the slot is below the cover layer, said defect, is not visible, and therefore is not perceived as such by the final consumer of the sash.
  • a further advantage is therefore that of a significant cost savings in the production of the upright elements and transversal elements in which is no longer required that the upright and transversal engagement surfaces have tight tolerances.
  • a still further advantage occurs during assembly of the cover frame, a step now substantially simplified because no longer requiring particular attention from the installer, unlike the assembly of the frames typical of the solutions of the known art that, instead, always require particular attention and energy in the engagement between transversal element and upright element to eliminate as much as possible the slot between the two.
  • the locking element engages the transparent element, locking it on the weight-bearing frame, so that it is not locked to the weight-bearing frame by the cover frame.
  • the cover frame does not lock the transparent element on the weight-bearing frame and therefore has the sole purpose of being the cover on the outer side of the weight-bearing frame: the design and production of the weight-bearing frame are thus released from said need to support or lock the transparent element to the weight-bearing frame.
  • the locking element is easily obtainable for example by plastic moulding.
  • the locking elements have a simple shape, being of simple construction and being simple to use.
  • the locking element is positionable by means of the self-positioning lip, always at the same height on the weight-bearing frame.
  • the locking elements are placed on one line, not on several lines as in the solutions of the known art, thus making unnecessary the specific operations of positioning the locking elements, for example measuring or marking the weight-bearing frame.
  • each locking element is fixable to the weight-bearing frame by a screw, through a specially formed locking hole.
  • a still further advantageous aspect lies in the fact that the disassembly of the locking element is obtainable by means of its translation, in such a way that the screw is aligned from the locking hole to the release hole.
  • a retention septum is provided suitable, with its presence, to oppose said translation; advantageously the action of translation is to be such as to cause the modification or breakage of the retention septum that, therefore is suitable to maintain the locking elements in a secure position over time.
  • the cover frame is obtained by means of profiles provided with a special cavity suitable to be engaged by the locking elements.
  • the shape of the profile is very simple and constitutes the cavity itself in its entirety.
  • the locking elements being on one row, the cover frame has a single cavity, and not a multiplicity of cavities as in the solutions of the known art.
  • the cover frame is also suitable to totally cover each locking element and the screw that locks it to the weight-bearing frame, obtaining a further advantage from a point of view of its aesthetic impact.
  • the cover frame has, at its end, an acute angle suitable to perform the action of breaking the drop.
  • the joint element is planar, extending on a plane, and thus presenting a single height.
  • the joint element is obtained by sectioning an extruded piece.
  • the sash in its entirety is suitable to also comprise the frame, i.e., the part of the sash that is fixed to the sub-frame inside the architectural opening.
  • the casing is formed by the same components mentioned and described above; in other words, as is indeed widely visible in the drawings, the sash covered by this invention comprises both the casement, described above, and the frame.
  • the casement is movable, for example on special hinges, the one of the frame remains fixed and locked to the sub-frame to provide support for said casement.
  • the frame has the same components of the casement portion, in other words even the casing comprises the frame towards the inside, preferably in wood, and the cover frame mounted on it, by means of the locking elements.
  • the components that comprise the frame such as, for example, the presence of the cover layer in the upright element, or the method of locking the locking elements on the weight-bearing frame.
  • the components of the frame have the same characteristics as the corresponding components of the casement, but are different in size with respect to the latter.
  • the characteristics are substantially the same, and the distinctions are substantially minimal, for example the casing locking elements do not have the self-positioning lip 52 as that of the corresponding locking elements described above, but have a positioning flap 53 having the same purpose but different position, as visible in the drawings.
  • each of the variants described as belonging to a possible embodiment can be realized independently of the other variants described.
