Definitions

  • the invention relates to a pulling device for a folding door, in particular a folding sliding door, and a piece of furniture with a folding door, in particular a folding sliding door, which is provided with a pulling device.
  • Sliding doors are often used to close off openings in rooms or pieces of furniture, which are moved into a door compartment or into a parking space after the opening has been released, so as not to be a nuisance.
  • the US8336972B2 discloses a piece of furniture with a door compartment in which a displacement device is provided, by means of which the sliding door can be displaced within the door compartment.
  • the displacement device comprises a holding device in the form of a pair of scissors, by means of which a stop profile connected to the sliding door is held in a vertical orientation.
  • the displacement device also includes running rails, along which the stop profile is mounted in a displaceable manner by means of drives and can be pushed into the door compartment with practically no resistance.
  • the US9284761B2 discloses a piece of furniture with a displacement device by means of which a folding door can be displaced into a door compartment.
  • the folding door comprises two door elements, of which the first door element is connected at the front to a carriage that can be moved along a running rail that has two rail sections that are aligned perpendicular to one another and are connected to one another by a curved section, one of which is guided into the door compartment.
  • the second door panel is connected to the back with a stop profile, for example, according to the by a holding device US8336972B2 is held vertically.
  • the folding door is extended from the door compartment and unfolded. In the closed position, the door elements are aligned in a planar manner with respect to one another. In order to open the piece of furniture, the folding door is folded shut again, with the door elements assuming an angle not equal to 180° in an open position and being retracted into the door compartment, preferably aligned parallel to one another.
  • a hinge provided with a spring is known, by means of which door elements which are connected to one another in an articulated manner are rotated either into the open position or into the closed position after a central position has been exceeded.
  • the hinge is elaborately designed and requires fitting elements that are to be mounted on the upper edges of the door elements.
  • the DE202018100262U1 discloses a pulling device which assists in the closing of a folding door and is therefore provided with a lever arm which is pivotally attached to a first door panel, supported by a spring and guided with an end piece in a guide which is mounted on the second door panel.
  • the disadvantage of this device is that it is designed to be relatively expensive.
  • the present invention is therefore based on the object of creating an improved pulling device by means of which a folding door can be folded or guided from a closed position into an open position. Furthermore, a piece of furniture is to be created with a folding door that is equipped with the pulling device.
  • the pulling device according to the invention should make it possible to turn the door elements of the folding sliding door as far as possible against one another and preferably to align them parallel to one another.
  • the pulling device should have a simple structure and be easy to assemble. Furthermore, the traction device should be compact and take up little space.
  • the pulling device should preferably be constructed and arranged in such a way that it can be arranged in the space between the two door elements aligned parallel to one another.
  • the piece of furniture equipped with the pulling device should be easy to use and should not be subject to any significant restrictions with regard to the interior space.
  • the door elements are to be released from the closed position in a simple manner and automatically moved as far as possible into an open position.
  • the pulling device which is provided for a folding door, in particular a folding sliding door of a piece of furniture, which has a first and a second door element, which are pivotally connected to one another about a hinge axis, comprises a first pulling device unit, which can be mounted on the first door element, and a second A traction device mountable on the second door panel, and a traction cable connecting the first and second traction devices.
  • the first pulling device unit has a first pulling device body provided for installation on the first door element and a tension spring mounted in the first pulling device body, which has a first end piece with a first holding element mounted on a first end of the first pulling device body and which has a second end piece with a first end piece of the traction cable, which is guided via a first deflection element mounted on a second end of the first traction device body to the second traction device unit, which has a second traction device body provided for installation on the second door element, on which a second holding element is mounted at a first end to which the traction cable is connected.
  • the first door element of the folding door is connected by stop hinges, for example to a structural element such as a side wall or partition of the piece of furniture or to a stop profile that is held in a displaceable manner.
  • the folding door can be automatically transferred from the closed position into an open position, optionally with the door elements being aligned in parallel.
  • the door elements which are aligned planar to one another in the closed position, are automatically rotated in relation to one another around the hinge axis by the pulling device, which is why the folding sliding door can be operated easily.
  • the folding sliding door is locked or fixed in the closed position so that it is held securely and the piece of furniture cannot open itself.
  • a locking device is preferably used, which can be locked by pressing it first and unlocked again by pressing it again, as is described below for a folding device according to the invention.
  • the start of the opening process is preferably supported by a spring element which, if not already loaded, is loaded by pressing and pushes the opposing edges of the door elements away from the piece of furniture when unloading.
  • the two pulling device units are preferably mounted horizontally or perpendicularly to the hinge axis of the folding door. So that the traction device units do not collide when the door elements are folded together, they are preferably arranged offset one above the other vertically or parallel to the hinge axis of the folding door.
  • a first end piece of a spring rod is mounted on a second end of the second pulling device body, which has an exposed second end piece, by which a second deflection element is held, via which the pull cable is guided to the second holding element.
  • the spring bar can be a leaf spring, a bar spring or a helical spring, for example.
  • the front end piece of the spring bar, optionally of the leaf spring, can also be shaped into a deflection element and have annular windings, for example.
  • the first pulling device unit is mounted on the first door element in such a way that the first holding element faces the hinge axis of the folding door and the first deflection element faces away from the hinge axis
  • the preferably horizontally aligned second pulling device unit is mounted on the second door element in such a way that the spring rod with the second deflection element faces the hinge axis of the folding door and the second holding element faces away from the hinge axis. In this way, the pulling device exerts high torques on the door elements over the entire turning range.
  • the first retaining element is therefore connected via the tension spring to the tension cable, which is guided to the second retaining element via the first deflection element and preferably the second deflection element provided at the front end of the spring bar.
  • the second deflection element can be an eyelet or a deflection roller, for example.
  • the traction cable runs between the ends of the two traction device units that are spaced apart from one another, preferably until the desired folding angle of the door elements is reached, tension is maintained in the traction cable and the door elements are pulled against one another with maximum leverage.
  • the coil spring and the spring rod complement each other perfectly.
  • the spring bar ensures that the pull cable is pulled against the second door element on the front side of the spring bar. While the helical spring acts axially on the traction cable, the spring rod exerts a force perpendicularly on the traction cable.
  • the deflection elements lie at the ends of the traction device units that are distant from one another, which is why the traction cable is still held in this position and cannot sag.
  • At least one of the deflection elements is preferably a deflection roller which is held by a deflection bearing.
  • the deflection bearing is preferably held by means of a pivot bearing so that it can be rotated upwards or downwards. By tipping the deflection roller downwards or upwards, the traction cable is automatically guided past the first traction device unit at the top or bottom when the door elements are folded together.
  • the first and/or the second holding element is preferably held by a holding carriage which can be displaced and locked along a holding rail.
  • the traction cable can therefore be pretensioned as desired so that on the one hand the force required to planarly align the door elements in the closed position is not too high and on the other hand the force to unfold the door elements into the open position is sufficiently high.
  • the traction cable preferably runs parallel thereto and does not exert any torque on the door elements.
  • the door elements are fixed in the closed position and can be secured with simple means.
  • the folding door can be opened, for example, by means of the folding device described below, or in a simple manner by means of an externally mounted spring, for example a leaf spring or a spiral spring. By pressing the door elements perpendicularly in the direction of the piece of furniture, the compression spring is charged, which then initiates the folding process and opens the folding door so far that the pulling device can take effect.
  • the functions of rotatably holding two door panels, locking two door panels and automatically folding two door panels are preferably integrated into a folding device as described below.
  • This folding device comprises a first coupling wing, which is connected to the first door element, and a second coupling wing, which is connected to the second door element, and a coupling shaft, by which the two coupling wings are articulated to one another, and with a mechanical energy store which is on the two coupling wings acts.
  • the two coupling wings each have a first wing part, which is provided for connection to the associated door element, and a second wing part and a wing shaft, which articulately connects the first and second wing parts that correspond to one another, and that a bearing body is provided , which holds a bearing element for holding the coupling shaft and at least one bearing piston, which is surrounded by a helical spring that serves as an energy store, and which bearing body is articulated by the two coupling wings to a loading carriage, which has a bearing opening for receiving the at least one bearing piston and which is mounted in an axially displaceable manner on the at least one bearing piston.
  • bearing pistons aligned parallel to one another are preferably held displaceably by the bearing body and give the folding device increased stability.
  • Bearing bushes are preferably held in the bearing openings of the loading carriage, which ensure that the loading carriage is always held in an axially displaceable manner, aligned parallel to the bearing body.
  • the coupling wings are preferably folded up and down symmetrically to one another.
  • the loading carriage is moved back and forth along the bearing piston and the energy store is charged or discharged or the coil springs are tensioned or relaxed.
  • the energy store is charged when the loading carriage travels in the direction of the bearing body.
  • the door elements are transferred into the closed position in which they are aligned in a planar manner and are preferably locked by means of a locking device.
  • the locking device is preferably integrated into the folding device, but can also be mounted externally, for example on the underside, on the top side or on an intermediate wall of the piece of furniture.
  • the loading carriage is pushed back by the compressive force exerted by the coil springs and returned to the starting position.
  • the first wing parts and thus the two door elements are rotated against one another and preferably aligned in parallel.
  • the compression springs are held by the bearing pistons between the bearing body and the loading carriage and do not have to be fastened in order to develop the desired effect.
  • the helical springs are designed as tension springs and have one end piece connected to the bearing body and the other end piece connected to the loading carriage, the energy store is charged when the loading carriage travels in the direction away from the bearing body and is discharged again when it travels back in the direction of the bearing body .
  • the energy store is therefore charged after the folding or the parallel alignment of the door elements, which is why the folding door is automatically partially or completely transferred into the closed position after it has been pulled out of the door compartment, in which the door elements are aligned parallel to one another. In this case, there is no need for locking since the energy store is discharged.
  • the function of the folding device can therefore be advantageously changed and adapted to the wishes of the user by a simple modification, by using the helical springs either as compression springs or tension springs.
  • the pulling device and the folding device can therefore be advantageously combined with one another. Provision can be made for the door elements to be rotated from the closed position into an open position by the pulling device and then converted into a parallel alignment by the folding device. Alternatively, it can be provided that the pulling device is provided for moving the door elements from the closed position into an open position and the folding device is provided for unfolding the door elements aligned parallel to one another.
  • first wing part of each coupling wing is connected to the coupling shaft with at least one first bearing element and to the wing shaft with at least one second bearing element
  • second wing part of each coupling wing is connected to the wing shaft with at least one first bearing element and with at least a second bearing element with a carriage shaft is connected, which is provided on the loading carriage separately or together for each coupling wing.
  • the bearing body preferably comprises two bearing feet, each holding a bearing piston and delimiting a bearing space through which the coupling shaft passes and in which the first bearing elements of the first wing parts are connected to the coupling shaft. In this way, a compact construction of the folding device is realized.
  • the folding device comprises a locking device which can preferably be locked by moving the storage body and the loading carriage together and which can be unlocked again by moving the storage body and the loading carriage together.
  • the bearing body has a closure body which has a closure groove on one or both sides, into which a closure element that is connected to the loading carriage engages when the bearing body and the loading carriage move together.
  • the locking groove preferably runs around a central locking part and is designed in such a way that the associated locking element is guided cyclically around the locking part in the same direction during movements of the loading carriage and engages once in a locking area with each rotation and is released from the locking area again.
  • the folding door of the piece of furniture equipped with the pulling device according to the invention can advantageously be provided with one or more folding devices which have a hinge function and/or a locking function and/or a folding function.
  • the folding devices can perform the hinge function of the folding door alone or in combination with conventional hinges.
  • the folding device can be provided with a compression spring or a tension spring according to the desired function.
  • a locking device is preferably provided which can be unlocked by pressing on the door elements.
  • the locking device is preferably integrated into the folding device, but can also be mounted externally, eg on the top or bottom of the piece of furniture and interact with a locking element which is fastened to one of the door elements.
  • FIG. 1 shows a piece of furniture 1 according to the invention in the form of a cupboard 1 with a first door compartment 10, from which a folding door 11 has been pulled out, and a second door compartment 10, into which a one-piece sliding door 11 has been pushed.
