Definitions

  • the present invention relates to a door stopper for a sliding door assembly, comprising
  • the door stopper comprises two resilient detaining elements between which the carriage extends partly when it is held.
  • these resilient elements act on the longitudinal sides of the carriage. By acting on the two longitudinal sides of the carriage, the forces acting on the carriage in order to secure it can be dimensioned in such a manner that they compensate each other, so that the carriage does not deflect when it is being acted on. Due to these two detaining elements, the carriage can automatically be centred in its end position when it is being acted on.
  • the door stopper of US 2010/205772 A1 also comprises adjusting means for adjusting the detaining elements. By means thereof, it is possible to choose to close the door more forcefully or more gently, as desired.
  • a door stopper for a sliding door assembly according to the preamble of claim 1, wherein the adjustment means are configured to act on each detaining element on its side facing away from the side with which the detaining element is provided for acting on the carriage in order to detain it, wherein the adjustment means comprise a virtually U-shaped adjustment element, wherein the legs of the U-shaped adjustment element diverge from each other increasingly further towards their free end, wherein a first leg of the U-shaped adjustment element acts on the first leg of the leaf spring, at a fixed distance from the free end of said leg of the leaf spring, and a second leg of the U-shaped adjustment element acts on the second leg of the leaf spring, at a fixed distance from the free end of said leg of the leaf spring, and wherein said adjustment element is displaceably arranged with respect to the leaf spring, so that the legs of the adjustment element act on the legs of the leaf spring at a smaller or greater distance from the free ends of the legs of the adjustment element, in such a
  • the adjustment means are configured to act on each detaining element on its side facing away from the side with which the detaining element is provided for acting on the carriage in order to detain it. In this way, a door stopper whose detaining elements lose elasticity over the course of time can be readjusted for a longer period of time, so that the door stopper can be used for a longer period of time.
  • the running rail is suspended in a substantially horizontal position.
  • a door leaf is suspended from the carriage so that it is rollable with respect to the running rail by means of this carriage.
  • the spring forces which are exerted by this door stopper will then typically be directed virtually horizontally, with the spring force of the second detaining element being directed virtually opposite to the spring force of the first detaining element.
  • That side of a door stopper which, in the fitted position thereof in a sliding door assembly, faces the carriage is regarded as the front side of the door stopper in this patent application.
  • That side of the door stopper which faces away from the carriage is referred to as the rear side of the door stopper.
  • That side of the door stopper which is directed upwards is the top side and that side of the door stopper which is directed downwards is the bottom side.
  • the other two sides of the door stopper are the longitudinal sides. In most embodiments, these longitudinal sides will also be the longest sides which are directed sideways (and thus do not form a top side or bottom side).
  • the spring constant of the first-mentioned detaining element and the spring constant of the second detaining element of a door stopper according to the present invention are preferably virtually equal. In this way, it is simpler to prevent lateral deflections of the carriage when it is being acted on by the detaining elements.
  • the detaining elements are preferably arranged in such a manner that they act on the carriage virtually simultaneously when the carriage rolls towards the door stopper. This also contributes to preventing lateral deflection of the carriage.
  • the construction of the door stopper is preferably virtually symmetrical.
  • the object of the present invention is furthermore also achieved by providing a sliding door assembly, comprising
  • this door stopper is an abovementioned door stopper which comprises a virtually U-shaped adjustment element and if the running rail of this sliding door assembly comprises an access opening which is delimited on at least one side by a running surface for arranging the carriage thereon so as to be rollable, then the adjustment means preferably comprise an adjusting screw for displacing the adjustment element, in which said adjusting screw is adjustable via the access opening of the running rail.
  • said adjusting screw always remains accessible for adjusting or readjusting the position of the detaining elements with respect to the mounting body, irrespective of the way in which the running rail is fitted.
  • the running rail of the sliding door assembly may comprise such a passage opening which is delimited on at least one side by a running surface in order to arrange the carriage thereon so as to be rollable.
  • this passage opening is delimited on two sides by a running surface, so that the forces which are exerted on this running rail when suspending a sliding door leaf from a carriage which is fitted in this running rail and when displacing the carriage in this running rail, can be distributed more evenly across the running rail.
  • the running rail then typically has a virtually C-shaped opening, in which the opening between the legs of the C shape is directed downwards when the running rail has been suspended and forms said passage opening.
  • the running rail does comprise such a virtually C-shaped cross section, in which the access opening extends between the ends of the legs of the C shape, the running rail is furthermore preferably provided with a fitting rib in the cavity of the C shape on both legs at a distance from their ends and the mounting body of the door stopper preferably comprises a mounting flange on both longitudinal sides which are fittable over the respective fitting rib in order to secure the mounting body in the running rail.
  • This sliding door assembly then advantageously also comprises clamping screws by means of which the mounting flanges are clampable to the fitting ribs in order to secure the mounting body in the running rail.
  • Door stoppers according to the prior art are typically secured in the running rail by clamping them to the running surface for the carriage.
  • a running rail is typically twisted, as a result of which the running surface is no longer smooth and flat.
  • the illustrated door stopper (1) comprises a mounting body (8) and a leaf spring (6, 7), as can be seen in Figs 1 to 4 .
  • This illustrated door stopper (1) is configured to be fitted in a running rail (2) which is arranged at the top of a sliding door assembly (5), as can be seen in Figs 5 and 6 .
  • a door stopper (1) according to the present invention is, mutatis mutandis, also usable with sliding door assemblies having a running rail (2) which is arranged below the sliding door leaf (3), in which case said door stopper (1) is then fitted in said bottom running rail (2).
  • the leaf spring (6, 7) of the illustrated door stopper (1) is folded so as to be substantially U-shaped and accommodated in the mounting body (8), in such a manner that the free ends of the legs (6, 7) extend freely forwards with respect to the mounting body (8).
  • These legs (6, 7) extend at an intermediate distance from one another, with the intermediate space between the legs (6, 7) extending vertically inside the leaf spring (6, 7) and thus remaining unlimited towards the top and bottom.
  • Both legs (6, 7) are provided with a bend (9) which is directed towards the other leg (7 or 6, respectively) of both legs (6, 7).
  • This leaf spring (6, 7) may be made from stainless steel or from any other suitable material, such as for example from plastic. Furthermore, the action of this leaf spring (6, 7) is illustrated.
  • the mounting body (8) comprises a mounting flange (10) in order to mount it in a running rail (2) of a sliding door assembly (5).
  • the mounting body (8) can be clamped into this running rail (2), as can be seen in Figs 5 and 6 .
  • the running rail (2) may be provided with fitting ribs against which this mounting flange (10) can be clamped in order to mount the mounting body (8) in the running rail (2).
  • the running rail (2) then preferably has a substantially C-shaped cross section, with an access opening to the running rail (2) extending between the ends of the legs of the C shape.
  • the fitting ribs are then provided on both legs of the C shape at a distance from their ends.
  • the running rail (2) will typically be made from aluminium by means of extrusion, but could also be made of, for example, plastic.
  • the mounting body (8) will typically be made from plastic, but may obviously also be made from other suitable materials.
  • the access opening of the running rail (2) of the illustrated sliding door assembly is delimited on both sides by a running surface (19), on which carriages (4) of the sliding door assembly (5) are rollable, as can be seen in Figs 5 and 6 .
  • These figures show one carriage (4) from which a sliding door leaf (3) is suspended.
  • Such a sliding door leaf (3) is typically suspended using at least two such carriages (4).
  • the sliding door leaf (3) is then displaceable with respect to the running rail (2) between a closed position, as illustrated in Fig. 5 , and a completely open position.
  • Fig. 6 shows an open position between the closed position and the completely open position.
  • a carriage (4) of a sliding door assembly may come in several shapes and be provided with one or more wheels (20) in order to fit it in a running rail (2) so as to be rollable.
  • the carriage (4) comprises four wheels (20) which are rotatably fitted to a rotation shaft (21) in pairs and are in each case arranged on respective sides of the base body (22) of the carriage (4), so that they are rollable on the respective running surfaces (19) which extend next to the access opening to the running rail (2).
  • the knock is cushioned by a buffer element (18) which is fitted on the front side of the mounting body (8) of the door stopper (1), so that the carriage (4) does not recoil immediately and stays between the legs (6, 7) of the leaf spring. Due to the fact that the leaf spring comprises two legs (6, 7) which are spaced apart and extend an equal distance from the mounting body (8), the carriage (4) can act on both legs (6, 7) in a self-centring manner.
  • the force with which the legs (6, 7) of the leaf spring can be force apart may be adjusted, with the illustrated door stopper (1), by means of a virtually U-shaped adjustment element (13) and an adjusting screw (12).
  • the legs (14, 15) of the virtually U-shaped element (13) move increasingly further apart towards their free end. At their free end, they are then provided with an engagement element (17) which is directed towards the other leg (15 or 14, respectively).
  • a first leg (14) of this adjustment element (13) acts on the first leg (6) of the leaf spring, at a fixed distance from the free end of this leg (6) of the leaf spring, in such a manner that the engagement element (17) thereof engages in a cavity (16) in the first leg (6) of the leaf spring.
  • the second leg (15) of this adjustment element (13) acts on the second leg (7) of the leaf spring, at a fixed distance from the free end of this leg (7) of the leaf spring, in such a manner that the engagement element (17) thereof engages in an opening (16) in the second leg (7) of the leaf spring.
  • the adjustment element (13) is height-displaceable with respect to the leaf spring, with the engagement elements (17) being height-displaceable in the respective openings (16).
  • the adjusting screw (12) passes through a float (23) and through a part of the mounting body (8) which extends between the legs (6, 7) of the leaf spring and engages in the adjustment element (13).
  • This adjusting screw (12) is in this case situated on the bottom side of the door stopper (1) in such a manner that it is accessible via the access opening to this running rail (2) after the door stopper (1) has been fitted in the running rail (2).
  • the adjustment element (13) is raised or lowered.
  • the legs (6, 7) of the leaf spring move further apart. As a result thereof, only a smaller force is required to be able to push these legs (6, 7) apart by means of the carriage (4).
  • By lowering the adjustment element (13) the legs (6, 7) of the leaf spring are brought closer together. As a result thereof, a greater force is required to be able to push these legs (6, 7) apart by means of the carriage (4).
