Description

Application for an Invention Patent entitled:

"Bendable profile with sliding wall"

on behalf of Mario Amato, an Italian citizen

Description

The invention allows a specially shaped profile to produce and self-maintain any type of curvature or series of curvatures with the simple riveting or punching on the wings made more rigid and integral.

As it is known, for the realization of curved false ceilings with simple or double curvature, curved walls, interior finishes, numerous profiles in thin sheet metal with U, L, Z, etc. section have been conceived and on the market. capable of flexing and acquiring bends or double bends due to the presence of notches and slots that generate edges or surfaces of the segmented or finned section, for example as in the Utility patent application SA97U000021 of the same applicant.

These bendable profiles perform their task very well but are likely to give rise to further improvements in order to make them more functional and more rigid without losing in any way their original characteristic of flexibility. For example, it is an object of the present invention to give the segmented lateral surface of a U-section profile the possibility that the bending can be simultaneously equalized between all the fins but above all to give it greater rigidity once the desired curvature has to be fixed.

In particular, it is the main object of the present invention that when the U-section profile or with another section of interest is forced to assume a certain curvature, an additional element slides between the fins and assumes the necessary radius of curvature which is then locked by riveting. forming a continuous wall that gives rigidity and stability to the whole.

Further features and advantages of the invention will become clearer from the description of preferred embodiments and illustrated by way of indication and not of limitation in the attached drawings.

Fig. 1 shows, in a plan view, the fold lines of the section according to the present invention.

Fig. 2 shows the segmented side surface of the U-section.

Fig. 3 shows the sections that alternate along the longitudinal axis of the profile.

Fig. 4 shows in another embodiment the sections that alternate along the longitudinal axis of the section.

Fig. 5 shows the assembly of the invention according to a front side view.

Fig. 6 shows the whole of the invention in a three-dimensional view. Figure 7 schematically shows the invention to which a curve has been conferred.

In accordance with the drawings, (1) indicates a portion of a sheet metal strip with a series of notches by removing circular (2) triangular (3) and rectangular (4) sheet metal parts which make on a strip portion a succession of trapezoidal (5) and rectangular (6) segments possibly with beveled and rounded edges, and on another portion of the belt a continuous band (7).

Along the longitudinal development of the belt (1) there are fold lines (8), (9), (10) and (11).

Once folded according to the said folding lines, the strip creates a U-shaped profile having one of the vertical walls with a continuous surface (7) the other segmented with a succession of rectangular elements (6) connected to the other (7) by a succession of trapezoidal elements (5) which constitutes the base surface.

The fold lines (9) and (10) constitute the ends of the cantilever which can have a circular (12) or faceted curvilinear section, while the fold line (11) forms flaps at the top of the fins (6). A flat laminar element (13) consisting of a preferably metallic strip or tape whose smaller side dimension is less than the height of the fins (6) of the profile to which it is associated and has the same thickness and is positioned alternately between the fins between the internal surface face of a fin and the external surface face of the following fin, connecting the individual fins and obtaining a virtually continuous wall.

The flat laminar element (13) is held in position by the overhangs (12) and by the flaps at the top of the fins (6) which form guides on which the element (13) can slide or slide.

The overhang (12) is made, in an alternating succession, at the base of a flap in correspondence with the folding line (9) but not on the subsequent flap.

The longitudinal fold or flap (14) made at the top of the flap (6) by bending the free end of the flap itself is oriented towards the outside of the profile while the longitudinal fold or flap (15) on the subsequent flap is oriented towards the inside the section, in an alternating succession. The folds or longitudinal flaps (14) or (15) made at the top of each flap by bending the free end of the flap itself can have an inclination between 45 ° and 90 °.

In another embodiment of the present invention, the overhang (12) is made alternatively both on the external surface face of a fin and on the internal surface face of the fin that follows.

The maintenance in position of the flat laminar element (13) is obtained by the overhangs (12) and by the bends (14) and (15) at the top of the fins (6) which form guides on which the element (13) can slide . When the profile is forced to assume a certain curvature or a series of curvatures, the flat laminar element (13) that connects the individual fins (6), to constitute a virtually continuous wall, slides and at the same time bends consequentially assuming the same curvature of the wall (7), and can be locked and held once the element

(13) is fixed by riveting to the tabs (6).

In practice, the flat laminar element with longitudinal development (13) a

once associated with a special profile, preferably of the type

U-shaped, it creates a sliding wall along the direction

longitudinal section of the section so that the section can be

folded and easily locked, by riveting, to the curvature or the

series of curvatures conferred.

The invention lends itself magnificently to the realization of warping and supporting structures for panels or plates of any type or nature, suitable for

build a multiplicity of structures also in particularly forms

complex with remarkable speed and simplicity and therefore with obvious

economic benefits.

The connection between the various side flaps also assumes importance in the

in fact, the flaps can easily be subjected to storage and handling

deviations from perpendicularity by increasing or decreasing the radius

of folding flaps while the connection between them prevents them from clumping together

or single fins can flex around the bending axis, in practice yes

obtains a virtual continuous side wall with a noticeable increase

the strength and stiffness of the resulting profile.

From what has been previously described and illustrated it can be seen that the

found achieves the intended aim and objects.

The contiguous dimensions and shapes may be any according to

needs.
