Definitions

  • the present invention relates to a carriage for supporting a wing sliding along a given direction.
  • the present invention relates to a carriage for supporting a sliding wing, in which a constraining group able to facilitate assembly and maintenance of the carriage itself is provided.
  • the present invention relates to a carriage for supporting a sliding wing, in which a constraining group is provided, which can be selectively actuated and able to facilitate assembly and maintenance of the carriage itself.
  • carriages for windows, doors and the like able to support sliding wings, for example, but without limitation, sliding windows or doors
  • a movable equipment provided with two rotatable parts, for example, but without limitation, rollers, wheels and other similar rotatable bodies, so shaped as they can be associated with a track carried rigidly relative to the frame of the window or door; and an outer casing supporting the movable equipment.
  • the casing is connected rigidly to the sliding wing in correspondence of a substantially prismatic seat, laterally delimited by longitudinal grooves.
  • the movable equipment is interfaced with the casing by means of shaped element-tappet couplings in such a way as to be movable with respect to the latter along a given direction in order to allow variations of the position of each rotatable part relative to the casing, and thus to allow the adjustment for height of the sliding wing relative to the track below.
  • the above-mentioned patent EP 563015A1 by GIESSE S.p.A describes a cam carried transversely to the walls of the casing and provided with a curved lower profile substantially J-shaped which engages two curvilinear guides obtained in the lateral walls of the movable equipment and shaped in a substantially similar manner to the cam to associate each longitudinal displacement of the movable equipment with a simultaneous transverse component.
  • the adjusting device is completed by a longitudinal screw carried by the casing, which engages a threaded seat of the movable equipment in such a way that, by acting on the screw, it is possible to generate longitudinal displacements of the movable equipment.
  • An adjusting device like the one just described results to be easily producible, but entails the disadvantage of concentrating the entire load of the supported wing on the small portion of the lateral walls of the casing in which the grooves are obtained, which, as a consequence, may deteriorate rather easily.
  • the constraining device of the movable equipment inside the casing consists of the engaging of a pair of horizontal slots obtained in the lateral walls of the movable equipment by a pair of projections carried internally by the casing. These constraining slots are snap engaged/disengaged by exploiting the elasticity of the projections which in this way tend to wear out and rapidly lose their abutment function.
  • the present invention relates to a carriage for supporting a wing sliding along a given direction.
  • the present invention relates to a carriage for supporting a sliding wing, in which a constraining group able to facilitate assembly and maintenance of the carriage itself is provided.
  • the present invention relates to a carriage for supporting a sliding wing and in which a constraining group is provided which can be selectively actuated and able to facilitate assembly and maintenance of the carriage itself.
  • the object of the present invention is to provide a carriage for sliding windows, doors and the like that allows the disadvantages described above to be solved, and which is suitable to satisfy a plurality of requirements that to date have still not been addressed, and therefore, suitable to represent a new and original source of economic interest and capable of modifying the current market of carriages for sliding wings.
  • a carriage for supporting a sliding wing is constructed, whose main characteristics are described in at least one of the appended claims.
  • a further object of the present invention is to construct a carriage, provided with a casing and a movable equipment, in which assembly and disassembly of the movable equipment may take place in a rapid and safe manner without damage to parts even following couplings and discouplings repeated several times, keeping unchanged the functionality of the carriage itself.
  • a casing and a movable equipment are further constructed, which are able to be mutually coupled in a carriage for supporting a sliding wing; the main characteristics of this casing and this movable equipment are described in at least one of the appended claims.
  • a further object of the present invention is to provide a method for assembling a carriage for supporting a sliding wing, this method being suitable to satisfy a requirement that to date has still not been addressed and, in particular, to stably couple a respective casing and the corresponding movable equipment by means of a succession of steps of simple execution and therefore, suitable to represent a new and original source of economic interest and capable of modifying the current market of carriages for sliding wings.
  • a method that is validly usable for assembling a carriage for supporting a sliding wing is also provided, whose main characteristics are described in at least one of the appended claims.
  • number 1 indicates, in its entirety, a preferred embodiment of a carriage for supporting a sliding wing, for example the leaf of a window or door or the movable part of a sliding railing.
  • the carriage 1 comprises an outer casing 7 and a movable equipment 2 housing at least a roller 3, typically, but without limitation, a wheel or a caster, suitably shaped to engage a track, known and therefore not shown, and to give to the carriage 1, and thus to the wing supported thereby, translation freedom along a first longitudinal reference direction D, which henceforth shall be referred to as first longitudinal direction.
  • the carriage 1 comprises a constraining group 40 to fasten the movable equipment 2 inside the casing 7 and to facilitate the use of the carriage 1 itself during assembly, transport, installation or maintenance.
  • the carriage 1 comprises an adjusting device 20 and a balancing device 70 for regulating the position of the movable equipment 2 relative to the casing 7, and a guiding device 30 that, in use, is suitable to constrain the relative motion of the movable equipment 2 with respect to the casing 7 along a given trajectory, as will be better described below.
  • the movable equipment 2 presents substantially parallelepipedal shape with two first lateral walls 4a positioned according to the longitudinal direction D and parallel to each roller 3, supported by them by means of a transverse pin 9 carried in a freely rotatable manner by the same first lateral walls 4a.
  • the movable equipment 2 comprises only a roller 3 carried by the respective pin 9.
  • the movable equipment 2 presents a pair of holes 6 able to support the pin 9 transversely to the first lateral walls 4a.
  • the length of the pin 9 is modulated in such a way that the pin is completely housed inside the movable equipment 2 and does not engage, in use, the casing 7.
  • each second wall 4b of the outer casing 7 faces a respective first wall 4a of the movable equipment 2.
  • the guiding device 30, the balancing device 70 and the constraining group 40 of the movable equipment 2 are positioned inside the first space 8 in the interspace between the movable equipment 2 and the casing 7. In this way, such a guiding device 30, such a balancing device 70 and the constraining group 40 are not easily accessible from outside of the carriage 1 and, in use, are well protected from external agents which might damage them.
  • the guiding device 30 comprises at least a guide 31 coupled to at least an abutment 32. More in particular, each guide 31 comprises a first shaped element 31 carried by the second lateral walls 4b inside the first space 8 and each abutment 32 comprises a second shaped element 32 projecting externally to the movable equipment 2 from the first walls 4a.
  • the guiding device 30 is constructed in such a way that, maintaining the dimensions of the movable equipment constant, the load of the supported guiding device, which can reach considerable values, is distributed in a uniform manner on a wide interface between the guide/s 31 and the abutment/s 32 to minimise the pressure which the same guiding device is subjected to.
  • each first and each second shaped element are preferably, but without limitation, shaped like an inclined plane and comprise respectively a first and a second surfaces 33 and 34, each of which is inclined by a given angle ⁇ of inclination relative to the first longitudinal direction D; each first surface 33 being shaped in such a way as to be able to slide freely relative to a corresponding second surface 34.
  • each first shaped element 31 engages only a second shaped element 32 and the casing 7 supports the movable equipment 2 by means of a pair of first shaped elements 31 facing each other and positioned symmetrically with respect to a longitudinal median plane M of the carriage 1 containing the first longitudinal direction D, as shown in figure 2, in which it is represented for the sake of convenience through the same line of the first direction D itself.
  • this median plane M is longitudinally positioned in centreline both for the casing 7 and for the movable equipment 2.
  • the two pairs of first shaped elements 31/second shaped elements 32 are positioned at opposite site each from the other with respect to the pin 9 so as to balance, in use, the position of the movable equipment 2 inside the casing 7 and to prevent any oscillation of the movable equipment 2 about the pin 9.
  • the guiding device 30 ensures that with each longitudinal motion of the movable equipment 2 inside the casing 7 is associated a simultaneous movement along a second direction Q transverse to the first longitudinal direction D and shown in figure 4 only.
  • the guiding device 30 is therefore possible indirectly to adjust the position of the roller 3 and of the wing supported along the transverse direction Q, longitudinally translating the movable equipment 2.
  • the adjusting device 20 comprises a regulating member 21, able to act as abutment for the movable equipment 2 along the first longitudinal direction D, and a blocking member 22 for blocking the position of the regulating member 21, able to maintain the regulating member 21, and thus also the movable equipment 2, fixed in a given position relative to the casing 7. Furthermore, the adjusting device 20 is accessible from the outside of the casing 7 in such a way that it is possible to adjust the supported wing at any moment, even following the installation of the carriage.
  • the blocking member 22 is housed in a selectively releasable manner inside the second space 25 in such a way that the adjusting device 20 can be extracted from the carriage 1 during the maintenance operations, and replaced, if necessary.
  • the terms regulating member 21 and screw 21 shall be used indifferently based upon the context.
  • the carriage 1 further comprises a constraining group 40 positioned between the movable equipment 2 and the casing 7 to maintain the movable equipment 2 stable inside the casing 7 preventing the movable equipment 2 from accidentally slipping out of the casing 7 itself; this characteristic is particularly useful in absence of load, for example, but without limitation, during the steps of assembly, transport, installation and maintenance of the carriage 1.
  • the constraining group 40 comprises an abutment device 45 carried by the movable equipment 2 and a support device 46 carried by the casing 7; these latter two devices are mutually interfaced so as to prevent the movable equipment 2 from slipping out of the casing 7 itself.
  • the abutment device 45 comprises at least a first abutment member 41 and at least a second abutment member 44 positioned at opposite sides with respect to the pin 9, and the support device 46 comprises at least a first support member 42 and at least a second support member 47 positioned remotely one from the other, facing each second abutment member 44 and each first abutment member 41 respectively, and able to cooperate to hold the movable equipment 2 stably inside the first space 8 in the casing 7.
  • These first and second abutment members 41 and 44 project externally to the movable equipment 2 and may preferably, but without limitation, have the form of a tongue or tooth projecting from the respective support walls.
  • the first abutment member 41 projects from a wall transverse to the first lateral walls 4a from the same side of the adjusting device 20/regulating member 21.
  • the movable equipment 2 comprises a pair of second abutment members 44 projecting from the first lateral walls 4a symmetrically with respect to the median plane M and suitable to engage a pair of respective support members 42 projecting internally to the first space 8 from the second lateral walls 4b.
  • each abutment member 44 is usually, but without limitation, positioned below a second shaped element 32 close to the lower edge of the movable equipment 2.
  • This feature has the advantage of being able to use a single lateral projection 71 to embody at the same time both a second shaped element 32 associated with the guiding device 30 and an abutment member 44 associated with the constraining group 40; naturally, this choice entails simplification of the production process of the carriage 1.
  • the second support member 47 is carried inside the first space 8 by the casing 7 at the same side of the adjusting device 20/second space 25 to couple, in use, to the first abutment member 41.
  • the end of the regulating member 21 able to engage the movable equipment 2 comprises the second support member 47, in such a way that, by using only a mechanical element, for instance a screw, it is possible to provide both the regulating member 21 and the second support member 47.
  • This choice also entails a number of advantages of the functional and economic type such as, for instance, reduction of the components required and simplification of the design and the production of the carriage 1.
  • the second support member 47 in the first operating position P the second support member 47 is entirely housed inside the second space 25 and, without engaging the first space 8, it is separated from the first abutment member 41; in this condition the constraining group 40 is non-operative because the movable equipment 2 is supported only at opposite side from the second space 25 so it may spill out of the casing 7 by rotating it about the first support members 42.
  • the second support member 47 is in the operating position P' when it engages the first space 8 and projects inside the first space 8 in portion sufficient to maintain the movable equipment 2 far from the second space 25 so as the second abutment members 44 are facing the first support members 42.
  • the movable equipment 2 is supported at two opposite sides respectively by the coupling of the first abutment member 41 to the second support member 47 and by the coupling of the second abutment members 44 to the respective support members 42, and is therefore held stably inside the first space 8.
  • second operating position P' it shall mean, here and below, each position in which the second support member 47 maintains the movable equipment 2 with its second abutment members 44 facing the first support members 42.
  • the constraining device 40 can comprise a contrast member 43 carried by the casing 7 inside the first space 8 at opposite side from the adjusting device 20/second space 25.
  • This contrast member 43 is suitable to exercise on the movable equipment 2 a thrust along the first longitudinal direction D constantly in the direction of the adjusting device 20, to maintain the movable equipment 2 in contact with the regulating member 21.
  • the contrast member 43 usually comprises an elastic foil 43 which is clearly visible in figure 3 and in the following ones.
  • the contrast member 43 comprises preferably, but without limitation, a third support member 49 suitable to be engaged by a third abutment member 48 carried by the movable equipment 2 to cooperate for maintaining the movable equipment 2 inside the casing 7.
  • the third abutment member 48 projects externally to the movable equipment 2 at opposite side from the first abutment member 41 and projects from a wall transverse to the first lateral walls 4a.
  • the movable equipment 2 further presents at least a stiffening rib 72 carried by a respective first lateral walls 4a to give stiffness to the first lateral walls 4a. More in particular, as it is clearly shown in figure 3, all the elements projecting from a first lateral walls 4a, in particular each second abutment member 44, each second shaped element 32 and each stiffening rib 72, are delimited laterally by a planar surface 4c parallel to the first wall 4a and can be produced by means of a single lateral projection 71.
  • the lateral surfaces 4c are indicate only in figure 2 with dotted lines, and are mutually separated by a first length L that approximates in defect the distance between the second lateral walls 4b of the casing 7 to allow the movable equipment 2 to be freely inserted inside the first space 8 and to maintain the first lateral walls 4a substantially parallel to the second lateral walls 4b.
  • the balancing device 70 of the movable equipment 2 comprises a pair of lateral projections 71 carried by the first lateral walls 4a and delimited by respective lateral surfaces 4c and, in use, it maintains the first lateral walls 4a of the movable equipment 2 constantly parallel to the second lateral walls 4b of the casing 7, preventing any oscillations of the movable equipment 2 about any longitudinal axis.
  • the pin 9 presents a length which approximates in defect the first length L so as to be completely housed inside the movable equipment 2.
  • this assembly method comprises the step of housing the pin 9 and the roller 3 inside the movable equipment 2 and the step of housing the adjusting device 20 inside the second space 25 of the casing 7. At this point, it is possible to proceed with the step of inserting the movable equipment 2 inside the first space 8 inside the casing 7, as shown in a sequential manner in figures 4, 5 and 6. First of all, it is necessary to ensure that the second support member 47 is in the first operating position P, meaning it is completely housed inside the second space 25, as the movable equipment 2 can be correctly inserted and slipped out only when the second support member 47 is in the first operating position P and therefore the constraining group 40 is non-operative.
  • the method described above allows a large number of practical advantages during transport, installation and maintenance of the carriage 1 thanks to the possibility of selectively actuating the constraining group 40 following the change in the position of the second support member 47 from a first operating position P to a second operating position P'.
  • the installer once he has actuated the constraining device 40, can freely handle the carriage 1 without holding the movable equipment 2 inside the casing 7 by hand.
  • this last step of changing the position of the second support member 47 between two different operating positions is perfectly reversible and therefore the constraining group 40 can be selectively actuated. For instance, varying the position of the second support member 47 from the second operating position P' to the first operating position P is necessary whenever the movable equipment 2 must be extracted from the casing 7, for example during maintenance operation of the carriage 1 or replacing of worn components.
  • the carriage 1 according to the present invention presents further advantages in addition to those already described.
  • the lack of slots and/or guides obtained in the first lateral walls 4a or 4b allows to construct the movable equipment 2 and the casing 7 directly by moulding, without further mechanical works, thus reducing costs and times for producing the carriage 1.
