Definitions

  • This invention relates to a carriage unit equipped with a stopping and damping device for carriage units of sliding doors of buildings or furniture and the like.
  • sliding doors of buildings or furniture require a carriage unit comprising at least one carriage which supports the sliding element of the door panel and which runs in a slide rail to allow the sliding door panel to move along the slide rail itself.
  • limit stop devices are used to limit the travel of the carriage along the rail to prevent the sliding door panel from impacting violently against the supporting frame structure of the building or furniture unit the door panel forms part of.
  • these limit stop devices are associated with the rail.
  • the limit stop device is substituted for a special stop device and damper which slows down and retains the carriage when the latter, moving along the guide rail, reaches it.
  • stopping devices and dampers comprise a fastening block which is fixed to the rail and is provided with at least one elastic retaining element.
  • the elastic retaining element is fitted and locked to the fastening block or is made as one with it and is elastically deformed when the carriage comes into contact with it, slowing the motion of the carriage and "gripping" it in such a way as to hold it back.
  • a stopping and damping device may also comprise a cushioning bumper designed to absorb part of the impact of the carriage against the fastening block to assist the damping effect of the elastic retaining element.
  • the elastic retaining element may be a protuberance located on the underside of the fastening block (as described in document CH 2 331 459 , where it is made as one with the fastening block, or as in document FR 2 979 934 , where it is in the form of a leaf spring fixed to the fastening block) or on the top (as in document CA 2 331 459 , where the elastic retaining element is a leaf spring, either fixed to the top of the fastening block or made as one therewith).
  • the elastic force applied by the elastic retaining element on the carriage has a non-negligible component which is perpendicular to the horizontal plane defined by the rail on which the carriage runs.
  • the front of the fastening block may be shaped like a gripper (the two prongs being integral with the fastening block and being elastically deformable) which widens elastically around the carriage (or a protuberance thereof) to slow it down and stop it.
  • the working plane of the gripper defined by the prongs of the fastening block may be either parallel or perpendicular to the plane in which the sliding element supported thereby lies.
  • the structure of prior art stopping devices and dampers is not rigid and, generally speaking, does not allow selection of the retaining force if not by modifying the material of the fastening block or the material and/or the shims and the structure of the elastic retaining element.
  • the elastic retaining element owing to its elongate shape and the repeated deformation cycles it is subjected to, is exposed to rapid deterioration and/or strain hardening. This may lead to rapid breakage or, at best, to progressive loss of gripping capacity and/or increased noise.
  • Another problem with prior art devices is that it is difficult to fit them with systems for preloading the elastic retaining element (to allow varying the retaining force) without creating strain which, on account of the numerous deformation cycles they are subjected to during their working lives, does not accelerate deterioration and/or strain hardening.
  • Document EP 1 640 537 A2 shows a carriage which slides in a sliding guide and a related damping and stopping device, which is fixed to the sliding guide itself.
  • the carriage supports a sliding door and its front end is provided with a shaped nose which interacts with a rotating cam, the latter being attached to a front part of the stopping device facing the carriage.
  • the rotation axis of the rotating cam is perpendicular to the plane where the sliding door lies. Rotation of the rotating cam puts a helical return spring under tension, the return spring being constrained between the base of the stopping device and a front part of the cam itself.
  • the axis of the helical spring is substantially parallel to the line of motion of the carriage. Rotation of the rotating cam is started when it engages the shaped nose.
  • the cam itself is shaped in such a way that, acting onto the shaped nose while subjected to the return action of the tensioned helical spring, it can hold the carriage in contact with the damping means provided onto the side of the stopping device which faces the
  • Document EP 2 672 046 A2 discloses a stopping device acting on a runner which slides along a planar guide.
  • the plane where the planar guide lies is perpendicular to the lying plane of the sliding door associated to the runner.
  • the front part of the runner is provided with a shaped hooking projection, which is destined to interact with a corresponding shaped hooking projection provided onto the stopping device.
  • the stopping device has its shaped hooking projection located at a first free end of a rotating arm, which has its second end, opposite to the first, hinged to the base body of the stopping device by means of a rotation pin which is parallel to the lying plane of the sliding guide.
  • a helical spring whose longitudinal axis is parallel to the line of motion of the sliding runner, is compressed between two flanges of the base body of the stopping device.
  • the helical spring acts on the second end of the rotating arm via a related tappet.
  • Document EP 2 672 041 A2 illustrates a stopping device which may be fixed to a planar sliding guide, the stopping device being provided with an arm which rotates in the plane where the sliding guide lies, the rotation occurring around an axis perpendicular to said plane.
  • a leaf spring is associated to the rotating arm outside the latter, and acts between the rotating arm and side walls of the sliding guide to push the rotating arm towards the median axis of the guide itself.
  • a sliding runner running along the sliding guide may support a sliding door with its lying plane perpendicular to the lying plane of the sliding guide itself.
  • the sliding runner is provided with a hook interacting with the rotating arm, to push the latter against the side walls of the sliding guides so as to compress the leaf spring until the spring meets a seat in the hook where it is forced to enter by releasing part of the compressive elastic energy accumulated in the leaf spring itself. As a consequence, the sliding runner is stopped.
  • Document EP 2 672 041 A2 also discloses an alternative embodiment of the stopping device which comprises two prongs which may rotate around a common axis which is peerpendicular to the lying plane of the sliding guide. The prongs are kept far from each other by reaction springs which are located in between the prongs themselves.
  • the sliding runner is correspondingly provided with two shaped hooks.
  • Document EP 1 775 404 A1 discloses a carriage which runs along a rail and a related damping and stopping device which may be fixed either to the fixed frame of a sliding door (in particular to a top longitudinal element of the frame itself) or to the rail by means of a related base body.
  • the carriage supports a sliding door and is provided with a bearing roller which runs in the rail.
  • the bearing roller has its rotation axis perpendicular to the plane where the sliding door lies.
  • the carriage further comprises two auxiliary rollers located at a distance from each other along the direction of movement of the carriage on the rail.
  • the rotation axes of the auxiliary rollers are parallel to each other and lie in a plane which is parallel to the plane where the sliding door lies.
  • the rotation axes of the auxiliary rollers are perpendicular to the direction of movement of the carriage on the rail.
  • the damping and stopping device comprises a lever which is fixed to the base body and rotates therein around an axis which is perpendicular to the direction of movement of the carriage on the rail and parallel to the plane where the sliding door lies (i.e.
  • the lever has a first extremity and a second extremity located on opposite sides with respect to the rotation axis of the lever itself. At its first extremity the lever is provided with a contact roller whose axis of rotation is parallel to the axis of rotation of the lever itself. At its second extremity the lever is acted upon by a helical spring whose longitudinal axis is perpendicular both to the axis of rotation of the lever and to the plane where the sliding door lies.
  • the contact roller of the lever interacts with the auxiliary rollers of the carriage, causing the lever to rotate around its rotation axis against the action of the helical spring in a first rotation direction.
  • the action of the spring on the lever makes it rotate along a second rotation direction opposite to the first, blocking the contact roller between the auxiliary rollers of the carriage and stopping the carriage itself.
  • a "c-shaped" elastic damping element placed in the rail acts upon the carriage to dampen its movement when the contact roller gets blocked between the auxiliary rollers.
  • the aim of this invention is to overcome the above mentioned disadvantages by providing a carriage unit equipped with a stopping and damping device for carriage units of sliding doors of buildings or furniture and the like which allows high versatility in choosing the retaining force without necessitating modifications to the shape and/or material of the fastening block and/or of the retaining element.
  • Another aim of this invention is to overcome the above mentioned disadvantages by providing a carriage unit equipped with a stopping and damping device for carriage units of sliding doors of buildings or furniture and the like which reduces the risk of rapid deterioration of the device.
  • the stopping device and buffer 1 comprises a body 10 mountable in a rail 2 and a retaining device 12 for retaining a carriage 3 which runs in the rail 2.
  • the carriage 3 is designed to support and guide elements 4 of sliding door panels, in particular along the rail 2.
  • the retaining device 12 comprises a retaining lever 120 connected to the body 10 rotatably about an axis of rotation 121.
  • the rotatable connection may be obtained in several ways.
  • a first way may be that of using a through pin to hinge the retaining lever 120 and the body 10 to each other.
  • a second way may be that of shaping a protrusion of the retaining lever 120 in such a way that the protrusion can be inserted in a respective seat in the body 10.
  • the retaining lever 120 is movable about an axis of rotation 121 between a first end position and a second end position.
  • Limit stop elements 126 may be provided to determine the first and second end positions.
  • the drawings illustrate by way of non-limiting example an embodiment comprising a beak 127 on the retaining lever 120, inserted in a guide slot 128 formed in the body 10 and whose limits define, for the beak 127, the two end positions of the rotational movement of the retaining lever 120.
  • the retaining device 12 also comprises elastic opposing means 122 which generate a reaction torque opposing the rotation of the retaining lever 120 in a first direction of rotation "D1" from the first end position to the second end position.
  • the first direction of rotation "D1” thus corresponds to the rotational motion of the retaining lever 120 from the first end position to the second end position.
  • the reaction torque opposes this motion and tends to bring the retaining lever 120 back to the first end position.
  • the rotation of the retaining lever 120 in the first direction of rotation D1 is started by contact of a first lever arm 123 of the retaining lever 120 with predetermined portions of the carriage 3 when the carriage 3 approaches the body 10 during its movement along the rail 2.
  • the stopping and damping device 1 leaves a rest configuration (not illustrated) and moves into a condition which is intermediate between the rest configuration and a configuration where the carriage 3 is stopped.
  • the retaining lever 120 is in a retaining position where it retains the carriage 3 and, under the action of the elastic opposing means 122 is caused to adopt this retaining position.
  • This condition is illustrated in Figure 3 .
  • the stopping and damping device 1 is in the configuration where the carriage 3 is stopped.
  • the retaining lever 120 When, during rotation in the first direction of rotation "D1", the retaining lever 120 is in the retaining position where it retains the carriage 3 the action of the elastic opposing means 122 causes it to adopt this retaining position preferably by reversing the direction of rotation.
  • the retaining lever 120 preferably travels an angular stretch in a direction of rotation opposite to the first direction of rotation "D1". In this case, after reaching the position as close as possible to the second end position on account of the cam action applied by the predetermined portions of the carriage 3 ( Figure 2 ), the retaining lever 120 is urged by the elastic opposing means 122 towards the first end position in the retaining position on the carriage 3 ( Figure 3 ).
  • the retaining lever 120 is preferably a rigid element.
  • the value of the reaction torque which produces the slowing and retaining action on the carriage 3 by the retaining lever 120 depends on the state and properties of the elastic opposing means 122 which, being a different element from both the body 10 and the retaining lever 120, may be selected to define the most suitable reaction torque without substantial effects on the other components of the system (at least within wide limits of choice).
  • the predetermined portions of the carriage 3 which, upon contact with the first lever arm 123, start the rotation of the retaining lever 120 from the first to the second end position may be parts 30 at the front of the carriage 3.
  • the first lever arm 123 may comprise a shaped free end 129 which, when the retaining lever 120 occupies the retaining position on the carriage 3, engages matchingly shaped portions of the carriage 3 itself (for example, as illustrated in the drawings, the shaft of the wheels 31 of the carriage 3 or a guard or casing thereof, denoted in both cases by the numeral 32 in Figure 4 ).
  • the elastic opposing means 122 are operatively interposed between the body 10 and the retaining lever 120.
  • the stopping and damping device 1 further comprises presetting means 13 which act on the elastic opposing means 122 to select and/or set a predetermined value for the reaction torque on the retaining lever 120 at the first end position. This enhances the versatility of the device.
  • the elastic opposing means 122 constitute a third element distinct from the retaining lever 120 and the body 10, the value of the reaction torque can be preset with precision and relative confidence for the operation and durability of the system.
  • the elastic opposing means 122 may be embodied in several ways: for example by torsion springs operatively associated around the axis of rotation 121.
  • the elastic opposing means 122 comprise a helical spring 124 mounted so it is compressed between the body 10 and a second lever arm 125 of the retaining lever 120.
  • the second lever arm 125 is located on the side of the axis of rotation 121 opposite the first lever arm 123.
  • the helical spring 124 is mounted with its own longitudinal axis transverse to the retaining lever 120.
  • the longitudinal axis of the helicoidal spring 124 is transverse to the second lever arm 125.
  • the longitudinal axis of the helicoidal spring 124 is parallel to an axis of the carriage 3 which supports the element 4 of sliding door panels.
  • the presetting means 13 comprise an adjustment screw 130 which acts on one end of the helical spring 124 either directly or through actuating means 131.
  • the compression of the helical spring 124 at the first end position is set by screwing or unscrewing the adjustment screw 130.
  • setting the compression of the helical spring 124 is equivalent to setting the reaction torque of the elastic opposing means 122.
  • the adjustment screw 130 is engaged by a screw thread in the body 10.
  • the screw thread by which it is engaged is represented in the drawings by way of a non-exclusive example as a nut inserted in the body 10.
  • the adjustment screw 130 acts on a first end 1240 of the helical spring 124 either directly or through actuating means 131.
  • the actuating means 131 comprise a compression disc or washer 132 which is associated with a tip of the adjustment screw 130 and is moved along the axis of the adjustment screw 130 by screwing or unscrewing the latter.
  • the helical spring 124 may be constrained to a first pin 1241 associated with the body 10 and, at its second end 1242, to a second pin 1243 associated with the retaining lever 120, and more specifically, with the second lever arm 125.
  • the second pin 1243 may be formed on the adjustment screw 130.
  • the second pin 1243 may be formed on the compression disc or washer 132.
  • the compression disc or washer 132 may be integral with the tip of the adjustment screw 130.
  • the body 10 may be fixed to the rail 2 by means of suitable fastening screws 100. More specifically, by pressing on a first side 20 of the rail 2, the fastening screws 100 push the body 10 against a side 21 of the rail 2 opposite to the first side. If the retaining lever 120 is positioned between the fastening screws 100 and the first side 21, the retaining lever 120 (and more specifically, the second lever arm 125) is provided with through holes 101 through which the fastening screws 100 can pass. The through holes 101 are conveniently countersunk or elongate to prevent the fastening screws 100 from interfering with the rotation of the retaining lever 120 between the first and second end positions.
  • the retaining device 12 comprises a further retaining lever connected to the body 10 rotatably about an axis of rotation parallel to, or coinciding with, the axis of rotation 121 of the retaining lever 120.
