Definitions

  • the present application relates to an aluminum profile structure for door and window frames, particularly, but not exclusively, for door leaves which can slide with co-planar closure for items of furniture and the like, or indeed for sliding doors which do not have the doors coplanar but overlapping.
  • sliding door solutions are known which can be applied both to wardrobes and furniture in general, and also to door and window frames or to any other application of closing elements that require a reduced space in their open position.
  • these types of door are constituted by two or more door leaves, each one of which has brackets with rolling means guided by a rail, which is constituted by an upper guide and by a lower guide, respectively applied to the floor and to the ceiling of the compartment to be closed, the rail of one door leaf being adjacent and parallel to the rail of the other door leaf.
  • co-planarity of the door leaves is obtained during closing, although with different devices of greater or lesser complexity, involving, for each door leaf, a step of entrainment, along the respective parallel rails, and a step of pushing for the translational motion thereof into the adjacent bottom rail, the other end of which already supports and guides the other door leaf with which to align the door leaf in movement.
  • Italian patent for invention no. 1208152 which, in order to achieve co-planarity, uses an entrainment device wherein for each door leaf a pair of sliding guides is provided, by way of adapted brackets and respective sliding elements, such pairs of guides each comprising a rectilinear front guide and a second rear guide with curved end portion, while the first guide is provided with a part that diverges at right angles and is directed toward the second guide, in order to allow the translational motion of corresponding sliding elements of the corresponding door leaf, by simple translational motion of the door leaf to be moved.
  • each slideable door is provided by way of a corresponding bracket arranged on the edge of the outer side, each bracket being associated with a pair of trolleys that can slide, transversely to the door leaf, because they are supported and guided by a respective trolley which, in its turn, can slide longitudinally along the edge of the compartment to be closed.
  • the trolley is guided by a rail and by other containment tracks and is conditioned by an idle roller thereof which is engaged in one of the two longitudinal guides or cams, which are supported by and flank the supporting rail for sliding, in order to guide one of the two door leaves to overlap the other, when opening, and guide the same door leaf to align itself with the other, stationary door leaf, when closing.
  • the aim of the present invention is to solve the above mentioned technical problems, eliminating the drawbacks in the cited known art, by providing a structure that, applied in particular, but not exclusively, to sliding doors, makes it possible to increase the capacity of the aluminum profiles used and thus the capacity of the mechanisms which can slide.
  • an object of the invention is to provide a profile that is easy and quick to install and adjust.
  • Another object is to provide a profile that offers contained weight and size and thus low production costs.
  • Another object of the invention is to not substantially modify the aesthetics and the encumbrances of the profile.
  • Another object is to provide a profile that is structurally simple.
  • an aluminum profile for door and window frames characterized in that it comprises means for its pretensioning or for its precompression.
  • Figure 1 is a perspective side view of a profile according to the invention.
  • Figure 2 is a sectional view taken along the line II-II in Figure 1 in which the profile has been precompressed by two struts which thus compensate for the curvature, balancing each other out and returning the profile to a non-curved condition;
  • Figure 3 is a view similar to the previous one in which the profile has been pretensioned using only one strut;
  • Figure 4 is a view similar to the previous one in which the profile has been pretensioned by two ties which thus compensate for the curvature, balancing each other out and returning the profile to a non-curved condition;
  • Figure 5 is a view similar to the previous one in which the profile has been pretensioned using one tie;
  • Figure 6 is a view similar to the previous one in which the profile has been pretensioned using a tie and a strut;
  • Figure 7 is an exploded view of the profile with a tie and a strut
  • Figure 8 is a view of a detail of the invention in the version that uses a strut and a tie.
  • the reference numeral 1 generally designates an aluminum profile structure 2 for door and window frames, which is usable particularly, but not exclusively, for supporting door leaves which can slide with co-planar closure for items of furniture and the like.
  • the profile 2 has a base 3 from a lateral end of which protrudes at least one wall 4 within which is provided, along the longitudinal axis, with at least one through hole.
  • the at least one hole can, alternatively or otherwise, also be provided on other surfaces or walls or parts of the profile 2.
  • One or more struts or ties which can be inserted in the at least one hole go to make up the means of pretensioning or precompression for the profile 2.
  • two holes 5a and 5b are indicated, which are provided proximate to the ends 6a and 6b of the wall 4 and in which two struts or two ties are thus insertable.
  • the solution can however also work with only one hole and with only one strut or only one tie.
  • the length of the bars 7 can be less than or greater than the length of the holes 5a and 5b and the bars 7 can be used as struts or ties.
  • the ends of the holes 5a and 5b are internally threaded for interconnection with two pairs of reverse-threaded compression grub screws 8a and 8b and 9a and 9b, each of which interact with the facing ends of the bars 7, previously inserted in the holes 5a and 5b.
  • the screwing of the two pairs of compression grub screws 8a and 8b and 9a and 9b causes the compression of the steel bars 7, which thus make it possible to achieve a pretensioning of the aluminum profile 2 which acts as a beam for supporting and sliding of the door and of the mechanisms that enable the movement thereof.
  • One or more ties can be used in the aluminum profile 2, as shown in Figures 2 and 3.
  • a second solution lies in providing a second tie which is adapted to eliminate the rise caused by the first.
  • the profile 2 is put under equal tension on the lower and upper parts thus preventing the arching thereof.
  • the profile 2 will remain flat until the load applied (the doors) is such as to defeat the given pretensioning load.
  • the bars are used as ties.
  • the holes 5a and 5b are internally smooth and the ends of the bars 7 are externally threaded.
  • the invention is easy and quick to install and adjust and has contained weight and size and thus low production costs.
