Definitions

  • This invention relates to a carriage unit for sliding doors or windows, in particular forming part of a carriage unit for doors or windows known in the jargon of the trade as "lift and slide”.
  • carriage unit which, in the majority of the embodiments on the market, comprises a pair of carriages (main and secondary) so as to support the sliding sash in a distributed manner.
  • the connecting body is, on one side, connected to the lower part of the sash, and, on the other side, connected to the box-shaped frame by means of a coupling between a pin and an inclined slot (applied and made on the box-shaped frame and on the connecting body or vice versa depending on the solutions adopted).
  • a first problem is due to the "inclined slot" guide unit present on the carriages.
  • control mechanism starting from the operation of the handle and ending with the secondary carriage determines a sum of clearances due to the mechanical couplings in series which are present. More specifically, the drive unit connected to the carriage must couple with the slidable control rod connected to the handle.
  • a second problem is the reduced capacity of the assistance by the spring, due to the fact that as the lifting of the sash increases, the spring tends to "unload” and progressively reduce the relative contribution in the lifting of the sash.
  • Another problem encountered is due to the weight of the sash when it is lifted.
  • the weight of the sash always bears on the inclined slot and, in cascade, on the entire train of the mechanism until reaching the handle.
  • the aim of this invention is to provide a carriage unit for sliding doors or windows of the lift and slide type which overcomes the above mentioned drawbacks of the prior art.
  • the aim of this invention is to provide a carriage unit for sliding doors or windows of the lift and slide type which is able to use fully the effective stroke width of the carriages by its precise and adaptable connection to the system for movement of the door or window.
  • a further aim of this invention is to provide a carriage unit for sliding doors or windows of the lift and slide type which allows the opening and closing of the door or window without excessive effort for the user and with a high degree of stability of the movable sash in the open position.
  • a further aim of the invention is to provide a carriage unit for sliding doors or windows of the lift and slide type which may be adapted to any type of profile making the movable sash, that is, also in the case of small sized profiles, whilst maintaining high lifting strokes.
  • the carriage unit for sliding doors or windows of the lift and slide type comprises at least a main carriage, associated, in use, with a bottom crosspiece of a sash and resting on a horizontal base track to allow the sliding of the sash in both the open and closed directions.
  • the main carriage has a movement drive linkage comprising an operating arm interposed and connected, in use, between / to a rod slidable in the sash and means for lifting and lowering the sash positioned and acting on the main carriage.
  • the rod is connected, in turn, to a handle.
  • the handle is positioned on the sash for controlling the open position, with a lifting of the sash relative to the track, and the closed position, with a lowering of the sash relative to the track by rotating the handle from a first configuration to a second configuration, and vice versa, in such a way as to also activate the means for lifting and lowering.
  • the operating arm of the drive linkage has adjustable means for its secure connection with the rod.
  • the adjustable means are designed for adapting the position of the arm relative to the operating rod keeping unchanged the position of the rod and the relative configuration adopted by the handle and by the lifting means of the main carriage.
  • the carriage unit according to the invention can be used for sliding doors or windows of the lift and slide type and denoted by the numeral 1.
  • These doors and windows 1 essentially comprise: a fixed frame 2, at least one movable sash 3, a pair of carriage 4 and 5 forming the above-mentioned carriage unit and a control element 14 comprising a handle.
  • the sash 3 is slidable relative to the fixed frame 2 between a closed position (see Figure 1 ) and an open position (not illustrated).
  • the sash 3 is slidable horizontally along a fixed track 7 positioned at the base of the fixed frame 2 and, in its fully open position (not illustrated), can (purely by way of example) be superposed over a fixed sash 101 or a sash that is also mobile.
  • the pair of carriages 4, 5 are associated with the bottom crosspiece 6 of the sash 3 and are guided by the track 7 to allow the sliding of the sash 3 to and from the above-mentioned open and closed positions.
  • the carriage 4 will hereafter be called “main”, which, in the direction F2 of closing the sash 3, is positioned in front of the other carriage 5, which on the other hand will be called “secondary”, and is connected, in series with the main carriage 4.
  • the door or window 1 comprises, as indicated, a control handle 14 positioned on the sash 3.
  • the control handle 14 is connected to the carriage unit 100 using a connecting rod 23 slidable inside the vertical member of the movable sash 3.
  • the rod 23 is connected to a drive linkage 13 of the movement imparted by the handle 14 connected to the main carriage 4.
  • the main carriage 4 comprises a first box-type frame 8 having an upper portion 8a designed to be slidably coupled, in use, to the lower crosspiece 6 of the sash.
  • the main carriage 4 comprises a second frame 9 supporting a pair of wheels 10 and 11 positioned, in use, resting on the track 7.
  • the second frame 9 is designed to allow a pivoting movement of the two wheels 10 and 11 about a single pivot point P1.
  • the main carriage 4 comprises a link mechanism 12 for lifting and lowering the sash 3 relative to the track 7, corresponding to the open and closed positions, respectively, of the sash.
  • the link mechanism 12 is positioned and acting between the first frame 8 and, in use, the drive linkage 13 controlled by the handle 14 positioned on the sash 3.
  • the link mechanism 12 is also connected to the second frame 9 for allowing a movement, in both directions, of the pair of wheels 10 and 11 on the track 7 during the lifting and lowering movement of the sash 3 and keeping the same pair of wheels 10 and 11 centred relative to the first frame 8 during lifting or lowering.
  • the first frame 8 comprises its respective upper portion 8a shaped to form two coupling grooves S1 and S2 in a channel 6c made on the bottom crosspiece 6 of the sash 3.
  • the first frame 8 comprises a surface 15 and 16 shaped at each of its ends and configured for forming a contact guide cam for the hinge point P2, P3 of the link mechanism 12 connected to the drive linkage 13.
  • each shaped surface 15 and 16 forms a point for resting and supporting at a height (from the bottom) the first frame 8 to the hinge point P2, P3 at the raised opening position of the sash 3.
  • the link mechanism 12 comprises a first proximal movement rod 12a hinged, at three different points P4, P5, P2, to the first frame 8, to the drive linkage 13 and to the second frame 9, respectively.
  • the link mechanism 12 comprises a second rod 12b, distal relative to the drive linkage 13, hinged to the first frame 8 at a point P6, at one end, and at the other end, hinged at a single point P3 to the second frame 9 and to a rigid connecting unit 17 associated with the lower crosspiece 6 of the sash 3 for forming a rigid contact between second rod 12b and crosspiece 6 during the lifting and lowering movement.
  • the rigid connecting unit 17 is also associated, in series, with the second secondary carriage 5.
  • first and second rods 12a and 12b form two bilateral pairs of rods forming the movement mechanism.
  • pivot points or hinge points are formed by relative rotatable fixing pins between the various components.
  • the second frame 9 comprises two flat plates 9a, 9b partially housed in the first frame 8 and movable relative to the first frame 8.
  • each plate 9a, 9b is hinged, at its relative ends, to the link mechanism 12.
  • the two flat plates 9a, 9b forming the second frame 9 have a single pivot point P1 for the pair of wheels 10 and 11 in an intermediate area relative to the two hinge points P2, P3 with the link mechanism 12.
  • the pair of wheels 10 and 11 are rotatably fixed to a pair of horizontal rockers 18 and 19 having the central pivot point P1 hinged to the second frame 9.
  • the pair of rockers 18 and 19 forms a further frame inside the second frame 9 and makes the pair of wheels 10 and 11 independent from the second frame 9 and from the first frame 8.
  • the pair of wheels 10 and 11 are indirectly connected to the second frame 9 by the pivot point P1.
  • the link mechanism 12 connecting between the first frame 8, second frame 9 and drive linkage 13 therefore determines a movement for lifting or lowering the first frame 8, with the action of the handle 14, with consequent lifting and lowering of the sash 3 (see Figures 2 to 6 ).
  • the presence of the cam surfaces 15, 16 on the first frame 8 facilitates the lifting and lowering movements of the first frame 8 and also keeps the lifted position stable.
  • the main carriage 4 has a movement drive linkage 13 comprising an operating arm 25 interposed and connected, in use, between / to the rod 23 slidable in the sash 3 and the means 12 for lifting and lowering the sash 3 positioned and acting on the main carriage 4 (link mechanism 12).
  • the rod 23 is connected, in turn, to the handle 14.
  • the handle 14 is positioned on the sash 3 for controlling the open position, with the lifting of the sash 3 relative to the track 7, and the closed position, with the lowering of the sash 3 relative to the track 7 by rotating the handle 14 from a first configuration to a second configuration, and vice versa, in such a way as to also activate the means 12 for lifting and lowering (configuration at 0° for lowering and closing the sash 3 and rotated by 180° for lifting and opening the sash 3).
  • the operating arm 25 of the drive linkage 13 has adjustable means 24 for its secure connection with the rod 23.
  • the adjustable means 24 are designed for adapting the position of the arm 25 relative to the operating rod 23 keeping unchanged the position of the rod 23 and the relative configuration adopted by the handle 14 and by the lifting means of the main carriage 4 (as well as the secondary carriage 5, all upon assembly), see in particular Figures 2 , 5 and 7 .
  • an end 26 defining the fixed end point of secure connection with the connecting means 24 between the rod 23 and the operating arm 25.
  • end 26 being slidably insertable, in use, in the sash 3.
  • the adjustable joining means 24 are connected to the free end of the movement arm 25.
  • the adjustable connecting means 24 comprise a slide 27 articulated with the movement arm 25 and configured for the contact and the front joining with the end 26 connected to the rod 3.
  • connecting means 24 comprise means 28 for adjusting the relative position between the end 26 and the slide 27.
  • these adjusting means 28 are positioned between two contact surfaces 26a, 27a of the end 26 and of the slide 27, so as to allow a modification of the position of the slide 27 relative to the end 26 varying the angle of inclination of the arm 25 relative to the rod 23 and the lifting and lowering means 12.
  • the slide 27 adapts itself to the point of contact with the end 26 modifying its position and the angular position of the arm 25 relative to the rod 3 and the lifting means 12 thanks to the dual articulation of the arm 25 hinged, on one side, to the slide 27 and, on the other side, to the lifting means 12.
  • adjustable connecting means 24 also comprise means 29 for clamping the slide 27 to the end 26 and configured for locking the slide 27 to the end 26 in the defined position.
  • the adjusting means 28 comprise a toothed surface 27a and a counter-toothed surface 26a made on the corresponding front contact surfaces of the slide 27 and of the end 26 which can be coupled to or co-penetrated in each other to allow a plurality of separate positions between the slide 27 and the end 26.
  • clamping means 29 comprise a cap 29a which can be coupled on the outer surface of the slide 27.
  • the cap 29a comprises screw elements 29b passing through a slot-shaped cavity 29c made on the slide 27 and screwably engageable, in use, in a cavity 26b of the end 26 for locking the latter with the slide 27 in the adopted position of the latter.
  • the position of the end 26 on the rod 23 is relatively important during assembly of the movement accessories as, even if there have been errors in cutting and drilling holes in the rod 23, the assembly technician can modify the position between the slide 27 and the end 26 by loosening the screws 31 and, therefore, the coupling between the slide 27 and the end 26.
  • the technician can translate, in steps, the slide 27 until reaching the correct coupling between the slide 27 and the end 26 coupled in the cavity of the rod 23: this is without pulling or pushing the handle 14 or the means 12 in such a way as to not modify the configurations adopted by the handle 14 and by the lifting and lowering means 12.
  • this system which comprises a toothed and adjustable connecting joint, the movement given by the mechanisms which control the carriages is maintained in perfect timing between the handle at zero degrees when the sash is in the lowered position and the handle at 180° when the sash is in the raised position.
  • the structure and the functions of the elements of the secondary carriage 5 are very similar to those of the main carriage 4.
  • the secondary carriage comprises a first box-type frame 8 having an upper portion 8a designed to be slidably coupled, in use, to the lower crosspiece 6 of the sash 3.

  • the means 32 housed in the block 31 also form part of the adjustment means 38.
  • the means 32 are adjustable and allow adjustment of the height of the sash 3.
  • the means 32 are in contact with the link mechanism 12 forming a fixed contrast point when adjusting the height.
  • the above-mentioned screw means 32 are threaded and housed in the block 31.
  • the screw means 38 are used for adjusting the height of the sash 3 and in contact with the link mechanism 12 forming the fixed contrast point when adjusting the height H.
  • the first frame 8 comprises the vertical end wall 30 equipped with a through hole 30a.
  • the block 31 comprises a corresponding through hole 31a configured, together with the through hole 30a of the first frame 8, for allowing direct access from the outside of operating elements for adjusting the screw means 32 in such a way as to translate, in both directions, the block 31 and the second 9 and third 36 frame (the operating elements are not illustrated since of known type).
  • the adjustment system structured in this way allows the position of the sash 3 to be adapted/aligned if, after assembly, an imperfect alignment is found between the vertical member of the fixed frame and the vertical member of the movable sash.
  • the adjustment is extremely easy and fast thanks to the possibility of inserting a suitable tool inside the rear end of the secondary carriage and operating on the screw means 32.
  • the screw means 32 are a contrast with one of the pivot points of the connecting rod 12b lever which, in effect, is a fixed contact element: this therefore allows the translation of the block 31 which, in turn, acts on the second 9 and third 36 frame using the relative slotted end cavities 41 and 42.
  • the movement / translation of the third frame 36 determines a vertical movement (high-low) of the second frame 9 in contact with the first frame 8 due to the coupling between the slots 35 and 37 with the pivot point P1 of the wheels 10 and 11.
  • the vertical movement of the second frame 9 determines a lifting or lowering of the first frame 8 and, therefore, of the sash 3 in that area, thereby determining a correction of alignment of the sash relative to the fixed frame.
  • the carriage unit according to this invention fully achieves the pre-set aims.
  • the unit with the movement system using connecting rods and pairs of wheels with a reduced centre-to-centre distance and pivoting allows the "lift & slide" function to be achieved within smaller spaces with the advantage of being able to reduce the dimensions of the profile receiving the carriage unit and therefore with a competitive advantage in terms of cost of the profile.
  • the pairs of pivoting wheels allow a correct movement of the sash along the track even in the absence of linearity on the track caused by irregularities of the track or of the floor on which the door or window rests.
  • the connecting rod unit mounted on the carriages uses its reduced stroke and the maximum preloading of the rear spring in the position in which the connecting rods are kinematically in the most critical position, that is, at approximately 45°.
  • the entire general structure of the carriages described above ensures a constant and repetitive lifting height of the sash regardless of the weight of the sash and any clearances present in the kinematic mechanism.
  • lifting rods and first frame also allows, in the lifted position, to discharge the load of the sash on the connecting rods, on the wheels etc., but it is not transmitted to the handle which, in effect, will no longer be sensitive to the weight of the sash and the risk of undesired rotation.
