Definitions

  • the present invention relates to a rocker carriage for sliding door and window frames, in particular frames made of metal, wood or PVC sections.
  • the above-mentioned sliding door and window frames usually consist of an outer frame whose base (the portion which is the fixed crosspiece) is fitted with a longitudinal track. A pair (preferably) of wheels attached to the mobile crosspiece of the wing rest on this track.
  • the wheels are attached to a casing located close to each end of the wing, forming the box-shaped body of the carriage, which is attached to the internal part of the mobile crosspiece and, in the most simple solution, supports a single wheel.
  • the height of the latter is adjustable, relative to the box-shaped body, to allow the adjustments during wing assembly needed to compensate for any differences in the levels of the crosspieces or play resulting from assembly.
  • a more complete solution which facilitates compensation of the differences in the level of the track, uses carriages, each having a pair of wheels rotatably attached to a rocker arm.
  • the rocker arm pivots on the casing and the casing is fitted with fixing means, such as a grub screw or a screw, located and operating between the casing and the mobile crosspiece.
  • the carriage structured in this way further optimises adjustment of the flat surfaces on the frame, but also creates a disadvantage, given the need for an adjustment which is difficult, with the carriage mounted, due to the particular structure of the carriage and the presence of two elements - the box-shaped body and the "T" shaped plate, interacting to allow both the connection to the mobile crosspiece and the adjustment.
  • this structure may wear with the passage of time (especially on door and window frames which are very large and heavy), since the forces involved during sliding tend to concentrate on the central point, that is to say, the virtual pivot of the carriage, making wing sliding jerky, partly due to incorrect maintenance of the window or door frame flat surface.
  • the aim of the present invention is, therefore, to overcome the above-mentioned disadvantage by providing a rocker carriage for sliding door and window frames which is compact and simply and rapidly assembled, with an adjustment system which is precise and constant over time.
  • a one piece carriage for sliding door and window frames which comprises a pair of wheels which run on a fixed track and are attached in such a way that they turn idly to the ends of a box-shaped support body.
  • the body may be attached, with relative means, to a crosspiece which is part of a mobile frame, and support means for the mobile frame, and for adjusting the mobile frame relative to the track, made in the form of a single body on the support body and designed to allow an oscillating adjustment of the mobile crosspiece relative to the support body, in operation, according to the differences in the levels of the track and the mobile crosspiece.
  • sliding door or window frames 1 basically comprise a fixed frame 2, on which the lower portion which forms a fixed crosspiece is fitted with a longitudinal track 3. At least one pair of wheels 4a and 4b connected in such a way that they can turn idly to the ends of a box-shaped support body 5, slide on the track in a longitudinal sliding direction indicated by arrow S in Figures 1 and 3 .
  • the support body 5 may be attached, using appropriate means 6, to a crosspiece 7 which is part of a mobile frame 8 (again see Figure 2 ).
  • the carriage comprises support means 9 for the mobile crosspiece 7, said means also being used to adjust the mobile crosspiece 7 relative to the track 3 and being made in the form of a single body on the support body 5. This allows oscillating adjustment between the mobile frame 7 and the support body 5, in operation, according to the differences in the levels of the track 3 and the mobile crosspiece 7.
  • This adjustment is also made possible by the means 6 which attach the support body 5 to the mobile crosspiece 7.
  • These means are made on an end extension 10 of the support body 5, to prevent relative movements between the support body 5 and the mobile crosspiece 7 in the direction of sliding S, but allow a limited oscillation of the support body 5 relative to the connecting means 6, with constant contact of the mobile crosspiece 7 on the support means 9 irrespective of the levels of the track 3 and the mobile crosspiece 7.
  • the oscillating movements are indicated in Figure 3 by the Y' and Y'' axes and, the oscillation of the support body 5 relative to the means 6 is indicated by Z' and Z''.
  • the above-mentioned support and adjustment means 9 consist of an upper surface 11 of the support body 5 with an arced support profile for the mobile crosspiece 7 and for tilting between the latter and the support body 5 so as to form at least one contact zone Z with the mobile crosspiece 7, according to the differences in the levels of the track 3 and the mobile crosspiece 7.
  • the above-mentioned upper arced surface 11 comprises the central contact zone Z and two arced side zones Z1 and Z2, on either side of the central zone Z, connecting the latter to the support body 5.
  • the two side zones Z1 and Z2 have openings 12 and 13 forming an extension of seats for the wheels 4a and 4b on the support body 5.
  • these comprise the horizontal extension 10 of one end of the support body 5 with a through-seat 14 in which means 15 for connection to the mobile crosspiece 7 are loosely connected.
  • the connecting means 15 (see also Figures 4 and 5 ) comprise a tubular element 15 which is loosely held in the seat 14 and contains screw means 16 (a grub screw), designed to connect to the mobile crosspiece 7 (see Figure 2 and arrow F16) by making contact with it.
  • screw means 16 a grub screw
  • the grub screw 16 is stably connected to the tubular element 15, by interference due to plastic deformation of the inner surface of the tubular element 15 (with an undercut 15r), so as to form a fixed pin which allows the minimal oscillation between the mobile crosspiece 7 and the support body 5.
  • the tubular element 15 has a lower support base 17, in a single body, with a lower profile 18 which matches the profile of the track 3.
  • the carriage structured in this way is rapidly and easily fitted on the mobile crosspiece 7 using the grub screw 16 which connects the carriage to the mobile crosspiece and allows minimal oscillation, in operation, designed to allow automatic compensation of the differences in level between the mobile crosspiece 7 and the track 3, thanks to the central arced contact zone Z.
  • the weight of the mobile wing 8 on the carriage is discharged in the optimum manner by the arced configuration of the entire upper surface 11, meaning that the only element needed to connect the carriage to the mobile crosspiece 7 is the grub screw 16.
  • FIG. 6 to 9 An alternative embodiment of the carriage described above is illustrated in Figures 6 to 9 .
  • Document FR- A1-2 332 406 describes such a rocker carriage with respect to the preamble of claim 4 (second embodiment).
  • the support body 5 comprises, in the same zone and on both sides of the connecting means 6, the above-mentioned support and adjustment means 9 for the mobile crosspiece 7.
  • the adjustment means 9 and the connecting means 6 close to the carriage centre of gravity, it is possible to obtain an adjusting oscillation between the mobile crosspiece 7 and the support body 5, in operation, according to the differences in the levels of the track 3 and the mobile crosspiece 7.
  • the connecting means 6 comprise a central through-opening or seat 20, made in the support body 5 and in which the means 21 for connecting the support body 5 to the mobile crosspiece 7 are loosely held.
  • This through-seat 20 consists of a pair of angled walls 23 made inside the support body 5, set opposite one another and separated by a distance sufficient to form the seat 20, at the carriage centre of gravity B, for the loose passage of the connecting means 21.
  • the walls 23 also separate the means 6 and the wheels 4a and 4b.
  • the connecting means 21 comprise (see also Figures 8 and 9 ) a tubular element 24, loosely held in the central seat 20 of the support body and itself holding screw means 25 (a grub screw) designed for connection to the mobile crosspiece 7 and for connection, by interference due to plastic deformation, to the tubular element 24, thus allowing a minimal relative oscillation between the mobile crosspiece 7 and the support body 5 (see axes 50' and 50'' in Figure 7 ).
  • the tubular element 24 has a lower base 26, in the form of a single body, with a lower profile 27 which matches the profile of the track 3 and an arced upper profile 28.
  • the arced upper profile 28 is contained in a matching arced portion 29 on the support body 5, allowing the minimal oscillation of the tubular element 24.
  • support means 9 which comprise two upper surfaces 30 and 31 of the support body 5. These surfaces are separate and have an arced profile that extends by an amount at least equal to the diameter D of the tubular element 24. These arced profiles 30 and 31 are located on both sides of the tubular element 24, to allow constant contact between the mobile crosspiece 7 and the support body 5 in the event of the above-mentioned relative minimal oscillation between the support body 5 and the mobile crosspiece 7 (see axes 51' and 51'' in Figure 7 ).
  • the latter embodiment may be used, for example, for small sliding door and window frames, and where there is a limited working space for assembly of the carriage.
  • the two embodiments described use a simple structure to fulfil the preset aims, partly thanks to a single element forming the carriage, which is rapidly fitted without the need for adjustments after fitting. Thanks to the connection established, by means of the oscillations allowed by the connection with the tubular element and the arced surface, the carriage can adjust to the differences in level between the track and the mobile carriage.
