    Austrian Patent Office AT 12 684 Ul 2012-10-15
    Description: The invention relates to a carriage for a sliding leaf.
    The present invention is mainly in the sector of windows and doors and the home or housing device and in particular in the execution of frames or furniture with sliding sashes.
    Trolleys are known for both "hanging" and "hanging". Sliding sash, d. H. which are mounted for hanging on the upper edge of the wing, as well as for " standing " Sliding sash, d. H. those that are mounted on the lower edge of the wing, so that it rests directly on them.
    The invention relates in particular, without it thereby loses its generality, on carriages for hanging sliding sash.
    Hanging carriages are known, which comprise a central body which is rigidly coupled to the wing from which two arms protrude in opposite directions. These arms are rigidly connected to the central body, defining a substantially monolithic structure with two wheels pinched at its ends. These wheels are oriented so that they can roll on a running plane of the carriage, which is typically defined by a corresponding rail or guide rail.
    A disadvantage here is that the carriages often get stuck, which is mainly due to alignment error of the rail, which complicate the running of the wing.
    These alignment errors typically occur in structural subsidence due to e.g. B. from moisture or after impact.
    Furthermore, such alignment errors, even if they are of only minor extent, can generate an unpleasant noise when running, with the added disadvantage that the housing of the cabinet or the blind stick tends to amplify this noise like a resonance space.
    It is therefore the object of the invention to propose a carriage for a sliding sash, which overcomes the aforementioned disadvantages of the prior art.
    In particular, it is an object of the invention to provide a carriage for a sliding sash, which is able to facilitate the running of the wing, regardless of the state of the rail or guide rail.
    Another object of the present invention is to propose a carriage for a sliding sash, which is reliable and quiet.
    To achieve this object or to achieve the stated objectives, the invention provides a carriage for a sliding sash, which has the technical features that are specified in one or more of the appended claims.
    The invention will follow on the basis of preferred embodiments to which, however, it should not be limited, and further explained with reference to the drawings. In the drawings: FIG. 1 is a perspective view of a first embodiment of a sliding carriage according to the invention for a sliding leaf in a use configuration; FIG. 2 shows a side view of the carriage according to FIG. 1; - Figure 3 is a plan view of the carriage according to Figure 1; Figure 4 is a perspective view of a second embodiment of the inventive carriage for a sliding sash in a first configuration; 1/13 Austrian Patent Office AT 12 684 Ul 2012-10-15 - Figure 5 is a side view of the carriage according to Figure 4 in a second Ge consumption configuration; FIG. 6 shows a top view of the carriage according to FIG. 5.
    In the drawing, 1 and 100, a carriage for sliding sash according to two different embodiments of the invention. In both embodiments, the carriage 1 or 100 has a central body 2 or 102 with a section 2a which can be coupled to a sliding leaf 3. This couplable portion 2a can engage with a corresponding anchoring bracket 19 which is fixedly mounted on the wing 3.
    Preferably, the couplable portion 2a is at least partially defined by a threaded hole 4, into which a screw 20, which in turn can engage with the anchoring bracket, can engage.
    In this way results in a substantially rigid coupling between the wing 3 and the carriage 1 and 100, respectively.
    In other embodiments (not shown), the coupling between the wing and the carriage can also be at least partially of an elastic type, so that the rigidity of the overall assembly is reduced, which brings advantages in terms of a liquid movement.
    In the illustrated embodiments, the carriage 1 or 100 at least two arms 5 and 105, which are connected to the central body 2, 102 and extending therefrom in opposite directions. The arms 5 and 105 lie substantially in the same orientation as defined by the main extension direction B of the carriage 1 or 100.
    Preferably, the main extension direction B of the carriage corresponds to 1 or 100 of the feed or movement direction of the carriage 1 or 100 along a feed level A.
    Preferably, the carriage 1 and 100 slidably connected to a (guide) rail 6, which is fixedly fixed to a cabinet or a crossbar (not shown).
    It should be noted that this rail 6 defines the feed level A of the carriage 1 and 100, respectively. This feed plane A is preferably defined between the wing 3 and the carriage 1 and 100, respectively.
    In order to allow the running of the carriage 1 or 100 along the rail 6, a corresponding wheel 7 or 107 is rotatably mounted on each arm 5 and 105, which rolls on the feed level A of the carriage 1 and 100, see. 2 and FIG. 4.
    In particular, each arm 5, 105 extends between a first end 5a, 105a coupled to the central body 2, 102 and a second end 5b, 105b, respectively, overhanging the corresponding wheel 7, 107, respectively Carries pins.
    In the figures 1 to 3 a concrete embodiment, a first embodiment of the carriage 1 is shown. In this embodiment, the arms 5 are pivotally connected, wherein they can be pivoted relative to each other in the direction of each other and apart. The arms 5 in each case pivot about an axis D, which extends transversely, preferably orthogonally to the main extension direction B of the carriage 1 and substantially parallel to the feed plane A.
    In other words, the arms 5 can pivot with respect to each other according to a pivoting plane C, which extends substantially transversely to the feed plane A and substantially parallel to the feed direction of the carriage 1.
    Preferably, the arms 5 are pivotally connected to the central body 2 to pivot about the respective own pivot axis D transversely to the feed direction of the carriage 1. Thus, here is each arm 5 with respect to the central body 2 and therefore in 2/13 Austrian Patent Office AT 12 684 Ul 2012-10-15
    With respect to the other arm 5 pivotable about its pivot axis D.
    In the illustrated embodiment, the arms 5 are hinged to the central body 2 respectively at a respective hinge point 12 via a pivot pin or the like.
    Preferably, these hinge points 12 are separated from each other with respect to the couplable portion 2 a and arranged on opposite parts of the central body 2.
    Preferably, the hinge points 12 are arranged symmetrically with respect to a transverse central plane E of the main body 2.
    With "transverse, middle level E " is meant a plane which extends transversely, preferably perpendicular to the main extension direction B of the carriage 1.
    Preferably, each arm 5 has a stopper portion 9 which extends transversely to the prevailing main extension direction B of the carriage 1.
    The stopper portions 9 of the arms 5 are preferably opposite each other, so that they approach each other during the pivoting of the arms 5 and move away from each other.
    The function of these stop sections 9 will be explained in more detail below. The arms 5 are preferably designed substantially fork-shaped.
    In the illustrated embodiment, the arms 5 are designed substantially double forked.
    In other words, the arms 5 of the carriage 1 each have two bifurcated portions 13a, 13b, which are opposite and connected to each other in one piece.
    Accordingly, the arms 5 are shaped substantially "H" shaped.
    Each wheel 7 is rotatably connected to a first forked portion 13 a of the corresponding arm 5. In other words, the first bifurcated portion 13a at least partially defines the above-mentioned second end 5b of each arm 5.
    The second bifurcated portion 13b is pivotally connected to the central body 2 at the aforementioned hinge point 12.
    In other words, the second forked portion 13b at least partially defines the aforementioned first end 5a of each arm 5.
    The carriage 1 further comprises elastic or spring means 8 which act on the two arms 5 to exert on these arms 5 opposing moments. In this way, the elastic or spring means 8 allow the wheels 7 to be held in contact with the feed plane A of the carriage 1.
    More in detail, the spring means 8 act on the arms 5 to push them against the feed plane A and against the rail 6. Accordingly, the spring means 8, with reference to the aforementioned feed plane A, act in a manner to approximate the wheels 7 to each other.
    Advantageously, this allows to overcome connection and alignment error of the rails 6, whereby a sticking of the carriage 1 and in the wake of the wing 3 is avoided.
    By a degree of freedom from rotation of the carriage 1 is in fact possible together with the elastic effect to overcome any punctual deformation of the rail 6 and then return to an initial configuration.
    Preferably, the spring means 8 between the abutment portions 9 of the arms 5 in the sense of a thrust force are effective.
    In other words, the spring means 8 tend to deflect the stopper portions 91313 of the Austrian Patent Office AT 12 684 Ul 2012-10-15.
    These spring means 8 comprise at least one spring 10 which has two opposite ends 10a, each of which engages a corresponding stop portion 9 of the corresponding arm 5 and is held there.
    In the preferred embodiment, the spring means 8 comprise two springs 10, which are arranged mutually parallel and preferably in mirror image with respect to a central longitudinal plane F of the carriage 1. With "middle longitudinal plane F " is meant a plane which is transversal, preferably orthogonal to the transverse middle plane E.
    It should be noted that the main extension direction B is a major axis of the central longitudinal plane F.
    Preferably, the arms 5 are also independently inclinable with respect to the central longitudinal plane F of the carriage 1 about the main extension direction B. In other words, the arms 5 have the opportunity to "roll" so that they can follow any curvatures of the rail 6.
    With "roll" is meant that the arms 5 have the opportunity to twist around its own center axis. Preferably, this possibility of rolling is just a little more than a game, so that the functionality of the carriage 1 is not compromised.
    For this purpose, it should be noted that the two parallel-acting springs 10 tend to bring the arms 5 back into the position which is aligned with the central longitudinal plane F.
    In this embodiment, the second bifurcated portion 13b of each arm 5 is hinged to a corresponding hinge portion 14 of the central body 2, which is located at the hinge point 12. Each hinge portion 14 is penetrated by a through hole 14 a, in which a pivot pin 15 of the corresponding arm 5 is inserted. Thus, the aforementioned pivot axis D of the respective arm 5 is defined.
    In order to allow the aforementioned inclination, each through-hole 14a has two countersinks each extending from the central longitudinal plane F in opposite directions.
    It should be noted that in this way a small clearance in the coupling of the arm 5 and the central body 2 is made possible, whereby the arms 5 are allowed to incline with respect to the central longitudinal plane F.
    In non-illustrated embodiments, the hinge portion of the central body may be forked and the first end of the arm inserted into this crotch.
    In these embodiments, the first end of the arm has a throughbore which is "lowered" in the manner previously described. is, whereby the bank or rolling movement is made possible.
    Preferably, the carriage 1 further includes stopping means 11 for the relative rotation between the arms 5 in predetermined angular end positions. In other words, the stop or holding means 11 define two end positions which limit the relative rotation between the arms 5 and the central body 2. Advantageously, the carriage 1 is so able to dampen wells and connection errors well, without jeopardizing its functionality.
    Preferably, in this embodiment, the stop means 11 includes a tooth 16 projecting from the first end 5a of each arm 5 and engageable with a corresponding stop shoulder 17 of the central body 2.
    FIGS. 4 to 6 show a second embodiment of the carriage 100 according to the invention. In this, the arms 105 are rotatably connected to each other to turn back and forth in the direction of approaching or removing pivoted 4/13 Austrian Patent Office AT 12 684 U1 2012-10-15. The arms 105 are rotatable about a pivot axis G which extends transversely, preferably orthogonally to the feed direction of the carriage 1. The rotation axis G is substantially parallel to the feed plane A.
    Thus, the arms 105 can be pivoted with respect to each other according to the plane C, which is substantially transversal to the feed plane A and substantially parallel to the main extension direction B of the carriage 100, pivoted.
    Preferably, the arms 105 are pivotally connected to the central body 102 to tilt about its own pivot axis G, transversely to the feed direction of the carriage 100 ,.
    In other words, each arm 105 is pivotable about the pivot axis G with respect to the central body 102 and thus with respect to the other arm 105.
    In this embodiment, the two arms 105 are hinged to the central body 102 at the same hinge point 112, the central body 102 serving as a bearing on which the arms 105 are hinged substantially independently of each other. In this case, the first ends 105a of the arms 105 on the pivot axis G face each other.
    According to Fig. 4 to 6, the carriage 100 has two further arms 114, with each of which a corresponding wheel 107 is rotatably connected. These further arms 114 are preferably arranged substantially mirror-inverted with respect to the arms 105 with respect to the mentioned central longitudinal plane F of the carriage 100. Accordingly, in this example, the further arms 114 are both hinged to the central body 102 at the hinge point or hinge axis 112, respectively.
    Preferably, the arms 105 are freely rotatable about the hinge point 112 with respect to the further arms 114. Accordingly, the carriage 100 has two pairs of arms 105, 114, which are freely rotatable about the pivot axis G to each other.
    Thus, in the illustrated embodiment, the central body 102 is essentially a spigot about which the arms 105, 114 rotate and which centrally has the wing coupleable portion.
    Advantageously, the carriage 100 in this manner can easily overcome small misalignments between the rails without the risk of getting stuck.
    In the case of curvatures of the rails, the possibility of rotation between the two pairs of arms 105, 114 that always at least three, preferably four support points of the carriage 100 are given on the rail.
    Preferably, the further arms 114 are formed and arranged completely analogous to the arms 105; wherein both the arms 105 and the further arms 114 each have their own stop portion 109 and 118, which extends transversely to the extension direction B of the carriage 100.
    The abutment portions 109 of the arms 105 are preferably opposite each other so that they approach each other during the pivoting of the arms 105 and / or remove each other.
    Similarly, the stop portions 118 of the other arms 105 face each other so that they approach each other during the pivoting of the other arms 114 and / or remove each other.
    The function of these stop sections 109, 118 will be explained in more detail below.
    The carriage 100 further includes spring means 108 which act on the arms 105 to exert on these arms 105 opposite moments.
    Similarly, spring means 108 also act on the further arms 114 to exert on these opposing moments. Thus, the spring means 108 allow the wheels 107 to be held in contact with the feed plane A of the carriage 100. *** "
    More specifically, the spring means 108 acts on the arms 105 and on the other arms 114 to push them against the feed plane A and against the rail.
    In other words, with reference to the aforementioned feed plane A, the action of the spring means 108 tends to approximate the wheels 107 to each other.
    Advantageously, this allows to overcome connection and alignment errors of the rails by avoiding sticking of the carriage 100 and thus of the wing.
    By a degree of rotational freedom, the carriage 100 is in fact made possible, together with the elastic effect to overcome any punctual deformation of the rail and then return to an initial configuration.
    Preferably, said spring means 108 are effective between the abutment portions 109 of the arms 105 in the sense of a pushing force.
    Further, the elastic means (spring means) 108 between the abutment portions 118 of the other arms 114 in terms of a thrust force are effective.
    In other words, the spring means 108 tends to move the stopper portions 109, 118 away from each other.
    These elastic means 108 comprise a spring 110 having two opposite ends 110a, each of which is coupled to a corresponding stop portion 109 of the corresponding arm 105. Similarly, a spring 117 having two opposite ends 117a, each of which is coupled to a corresponding stop surface 118 of the further arms 114, is disposed between the further arms 114.
    Preferably, the carriage 100 further includes stopping means 111 for relative rotation between the arms 105 and 114, respectively, in predetermined angular end positions. These stop means 111 define two end positions which limit the relative rotation between the arms 105 and 114 and the central body 102. Advantageously, the carriage 100 is able to dampen wells and connection errors well, without jeopardizing its functionality.
    For this purpose, the arms 105 and 114 at the first ends 105a and 117a, respectively, a corresponding stop body 116 and 119, respectively. These stop members 116 and 119 can reciprocally engage each other to at least partially define the aforementioned stop means 111 for locking the rotation.
    The invention fulfills the stated tasks and achieves important advantages.
    Namely, rotatably connected and resiliently loaded arms allow damping of the vibrations due to deformations of the rails, as well as overcoming ground recesses and connection failures which cause the trolley to become stuck in the prior art.
    It is to be noted that the damping of the vibrations also enables a great reduction of the noise caused by the running of the carriage.
    In addition, a carriage with degrees of freedom on several axes increases the possibility of a good function. In fact, this possibility not only enables overcoming of bottom depressions and deformations that form along the rail, but also of alignment and alignment errors between two guide rails. 6.13
