Definitions

  • This patent refers to the field of cassetted retractable arms awnings, and it particularly concerns the shaft around which the piece of fabric is wound up.
  • the known shafts for the winding of the fabric consist of zinc plated steel tubes with a circular section and a concave site fit for containing the buttonholed end of the sheet, and the tube for the attachment and the blocking of the sheet inserted in it.
  • Said fabric includes, at one end, a buttonhole along its entire width, and, inside it, the tube for the attachment of the fabric.
  • Said tube, and the buttonhole around it, are firmly inserted in the concave site of the shaft.
  • the shaft and the fabric are inserted in a box with circular internal section, and internal diameter slightly bigger than the sum of the external diameter of the shaft and the double thickness of the complete winding of the fabric.
  • the presence of the buttonhole and its related seam produces a number of problems. Said seam, and its related cuff, produces an anomalous swelling on the external surface of the fabric winding, localized in correspondence of the seam itself. The dimension of the swelling increases at every winding turn, and for few metre long fabrics it is in the range of few millimetres.
  • a first problem that follows is the squashing of the fabric against the internal surface of the box, with the consequent need of a greater effort in the final part of the winding and in the initial part of the unwinding.
  • Another not less important problem is the possibility for the fabric to get damaged or dirty, with consequent serious aesthetic problems, starting from the first utilization period.
  • the new shaft makes it possible to eliminate the anomalous swelling due to the seam.
  • figure 0 shows the cross section of a shaft for awning, with its fabric (T) and box (C), used at present.
  • the shaft is made of a coil bent tube.
  • the section shows a concave site (A20), suitable for containing the tube for the attachment of the fabric.
  • Said site (A20) has a circular open section comprised between point (A2dx0) and point (A2sx0), which correspond to the ends of the circular section of the shaft (A0).
  • Said points are symmetrical about the shaft radius passing through the centre of the concave site (A20) and their distance is smaller than the external diameter of the tube (B).
  • Said tube is inside the buttonhole (Ta0) of the fabric (T), said buttonhole (Ta0) provided with a cuff in correspondence to the seam.
  • Said anomalous swelling causes the unwanted contact between the fabric and the internal wall of the box (C) itself.
  • the internal diameter of the box is slightly bigger than the sum of the external diameter of the shaft and the double thickness of the winding in normal position.
  • FIGS 1, 2, 3, 4 show the cross sections of the new shaft, the object of this invention.
  • Figure 1 shows the cross section of the new shaft (A), made of a bend coil bend tube (A1), of circumference (K), said shaft contains two concave sites, (A2) and (A3), focused in figure 2.
  • the site (A2) is fit for containing the tube (B) for the attachment of the fabric (T), and has a circular open section delimited by two points, (A2sx) and (A2dx). Said points are situated symmetrically about a line not passing through the centre of the shaft, and their distance is smaller than the external diameter of the tube (B) contained in said site.
  • the point (A2sx) is also an end point of the circular section of the shaft, while point (A2dx) is also an end point of the section of the site (A3).
  • Said site is fit for containing the cuff (Tr) in correspondence of the seam of the buttonhole of the fabric.
  • the section of the site (A3) is delimited by points (A2dx) and (A3dx), the latter being also an end point of the circular section of the shaft, together with point (A2sx).
  • points (A2sx) and (A3dx) belong to the circumference (K), while point (A2dx) is below it, i.e. it is closer to the axis of rotation of the shaft.
  • Figure 3 shows, in addiction to figure 1, the cross section of the fabric (T) entirely wound around the shaft (A). No swelling on the surface of the winding is evident, in fact by inserting the cuff (Tr) in the site (A3) it is possible to prevent the formation of the anomaly on the winding surface.
  • Figure 4 shows, in addiction to figure 3, the cross section of the box (C).
  • Said box being of the dimensions of the common boxes, with internal diameter slightly bigger than the sum of the external diameter of the shaft (A) and the double thickness of the total winding of the fabric.
  • a box with normal dimensions is fit for containing the shaft (A) and the fabric (T) comfortably, without provoking any contact between the fabric and the box, with the consequent problems that would follow.
