Definitions

  • the invention relates to a swivel joint for adjusting a functional part, in particular a head part, a foot part or an armrest, a piece of furniture, in particular a chair and / or piece of furniture, with an assembly lever for mounting the swivel joint on the piece of furniture and a swivel lever for carrying and adjusting the functional part, wherein the mounting lever and the pivot lever are mutually pivotably connected from an initial position to an end position about a pivot axis in an adjustment direction.
  • Swivel joints for adjusting a functional part of a piece of furniture are known in different configurations.
  • the swivel joints are mostly used to adjust a head part, a foot part or an armrest of a piece of seating furniture, which is typically upholstered furniture.
  • the swivel joints have a mounting lever with which the swivel joints are fixed to the respective piece of furniture.
  • a pivot lever is provided which carries the respective functional part and pivots the respective functional part around the assembly lever.
  • the assembly lever and the pivot lever are designed to be pivotable about a joint pivot axis in an adjustment direction relative to one another from an initial position into an end position.
  • the pivot lever When adjusting the pivot lever relative to the mounting lever in the adjustment direction, the user adjusts the pivot joint so far or pivots the pivot lever until he has set a comfortable position for the corresponding functional part. So that the functional part at least approximately maintains this position and does not accidentally move back into the starting position, the pivot lever is normally automatically locked in the corresponding position against being moved back in the return direction opposite to the setting direction. Usually this will achieved by a locking mechanism that interlocks in a form-fitting and blocking manner. An adjustment even further in the adjustment direction is possible at any time from the corresponding position of the pivot lever. In order to be able to move the pivot lever back into the starting position, the pivot lever must first be adjusted in the adjustment direction up to an end position. This deactivates the locking mechanism until the swivel lever has been swiveled back into the starting position. As a result, the lock is activated again in order to be able to lock the pivot lever again after a corresponding positioning along the adjustment direction.
  • the present invention is therefore based on the object of designing and developing the swivel joint mentioned at the outset and described in more detail in such a way that the costs of the swivel joint can be reduced without having to accept significant losses in terms of reliability and longevity.
  • a swivel joint according to the preamble of claim 1 in that the swivel lever in a plurality of locking positions provided between the starting position and the end position by a blocking, clamping engagement of at least one clamping element in a tapering one between a shaft and at least one the shaft partially accommodating wreath formed clamping gap when adjusting in a return direction opposite to the setting direction can be locked, that the shaft and the wreath are mutually adjustable from an adjusting position to a restoring position and that the shaft and the wreath in the restoring position when adjusting in the restoring direction positively and / or frictionally so are held aligned with one another, so that the clamping element is not clamped with play in the clamping gap and / or outside the clamping gap.
  • the securing of the pivot lever against a back adjustment in the reset direction after a completed adjustment of the pivot lever in the adjustment direction via a clamp enables a very precise adjustment of the pivot lever.
  • the setting of the pivot lever is, for example, not tied to a predetermined detent or pitch, as is typically the case with ratchets comprising pawls and toothed rings.
  • the clamping is provided much more by a clamping engagement of at least one clamping element in at least one clamping gap, whereby, if necessary, a stepless adjustment or locking of the pivot lever can be achieved.
  • the clamping gap tapers, so that when the swivel joint is adjusted in the return direction, the clamping element reliably comes into clamping engagement in the clamping gap.
  • the clamping gap is also formed between a shaft and a ring at least partially accommodating the shaft, which enables simple manufacture with high reliability.
  • the shaft and the ring are nevertheless provided so that they can be adjusted relative to one another from a setting position to a return position. So there is not always a clamping engagement of the clamping element in the clamping gap in all cases. Rather, this can be prevented in a targeted manner so that the pivot lever can be pivoted back into an initial position. From the starting position, the pivot lever can then be adjusted again to adjust the pivot joint in the adjustment direction until the desired position of the pivot lever is reached. In this position, the pivot lever is again secured against being moved back by a clamping engagement of the at least one clamping element in the at least one clamping gap.
  • the shaft and the ring in the reset position are held in a positive and / or non-positive manner with respect to one another when adjusting in the reset direction in such a way that the clamping element is jammed is prevented.
  • this is achieved in that the clamping element is held in a non-clamping manner, that is to say with a play between the shaft and / or the rim, in the clamping gap and / or outside the clamping gap.
  • This also supports a simple production of the swivel joint with a high reliability of the same. In this way, ultimately, low production costs can also be achieved with sufficient durability.
  • the shaft and the ring are provided in such a way that they can be adjusted back and forth between the reset position and the setting position partly jointly and partly against each other by rotating around the swivel axis of the swivel joint.
  • This allows a simple adjustment of the swivel joint in the adjustment direction and also enables a defined adjustment back in the return direction in order to reach the starting position.
  • the shaft and the rim have corresponding cams that rest against one another and / or slide against one another at least in sections when adjusting from the setting position in the return direction and / or at least in sections backwards.
  • the cams can thus be used, if necessary, for the shaft and the ring to rotate together about the pivot axis of the pivot joint by correspondingly resting the cams on one another. The cams then rest against one another, for example. Alternatively, however, the cams can also slide against one another and thus jump over one another, so that the shaft and the ring can be adjusted to one another in a simple manner between two basic relative positions, such as the setting position and the reset position.
  • the ring and the shaft can be positively connected in the setting position, in particular by contacting the cams, or frictionally so that when adjusting in the setting direction, the ring and the shaft rotate together, in particular concentrically, about the pivot axis. So is in a structurally simple manner in many intermediate positions when adjusting the The pivot joint or the pivot lever in the adjustment direction enables a potential locking of the pivot joint. This means that the swivel joint can also be set very precisely by the user.
  • the ring and the shaft can also be connected to one another in a form-fitting manner in the reset position, in particular by contacting the cams, or in a frictionally-fitting manner.
  • the ring and the shaft can be rotated together around the pivot axis when adjusting in the return direction. In this way, jamming of the at least one clamping element in the at least one clamping gap when the swivel joint is moved back into an initial position is prevented in a simple and reliable manner.
  • the rim and / or the shaft comprises at least one spring means
  • this can be provided in such a way that the spring means presses the cams of the rim and the shaft against one another in the reset position.
  • the connection between the rim and the shaft is pretensioned, in particular, in the direction of the setting position.
  • not only a defined connection and positioning of the shaft and rim is provided in the reset position.
  • the adjustment of the swivel joint from the reset position into the setting position is also reliably supported and thus ultimately also simplified.
  • a clamping of the swivel joint in a certain position of the swivel lever should usually be reliably guaranteed. Regularly, however, it should also be possible to adjust the swivel joint back to the starting position without any problems without corresponding jamming of the at least one clamping element in the at least one clamping gap. For this purpose, it is advisable if the at least one clamping element is held, in particular in a form-fitting manner, in the ring or in the shaft. To adjust the pivot joint between the set position and the reset position, it is also particularly expedient if the at least one clamping element is held on the rim or on the shaft with a significant amount of play.
  • the at least one clamping element is a roller. If necessary, the roller can then roll on the shaft or on the rim without causing increased friction.
  • a clamping element in the form of a roller reliably and easily reaches a clamping position within the at least one clamping gap.
  • the roller in the clamping position can only transmit the clamping forces to the shaft and the ring via linear contact surfaces. Therefore, if necessary, the at least one clamping element can also be configured differently than in the form of a roller.
  • a compact and long-lasting design of the swivel joint can be achieved if, for example, the ring and the shaft are each received at least partially in a housing element. This is all the more true if the ring is arranged at least partially rotatable about the pivot axis in the housing element.
  • the shaft can also be arranged in the housing element so as to be at least partially rotatable about the pivot axis. Both lead to a high level of functionality with little construction effort at the same time.
  • the housing element can have an adjustment stop for contact with an adjustment housing stop of the ring when adjusting in the setting direction and a reset stop for contact with a reset housing stop of the ring when adjusting in the reset direction.
  • the pivot joint can be adjusted back and forth between the setting position and the reset position in a simple manner by adjusting the pivot lever. The adjustment is triggered as required by the stops, but is at least supported.
  • the shaft has an adjustment stop for contact with an adjustment shaft stop of the ring when adjusting in the setting direction and a reset stop for contact with a reset shaft stop of the ring when moving in the reset direction having.
  • the pivot lever has to be pivoted, if necessary, in order to switch back and forth between the setting position and the reset position of the pivot joint, the adjustment being triggered or at least supported by the stops.
  • a very simple and thus inexpensive construction of the swivel joint can be achieved if the adjustment stop of the housing element and the adjustment housing stop of the rim on the one hand and the adjustment stop of the shaft and the adjustment shaft stop of the rim on the other hand are provided coordinated with one another.
  • the reset stop of the housing element and the reset housing stop of the ring on the one hand and the reset stop of the shaft and the reset shaft stop of the ring on the other hand are provided in the swivel joint in a coordinated manner.
  • the reset housing stop of the ring can strike the reset stop of the housing element before, after further adjustment in the reset direction, the reset shaft stop of the ring hits the reset stop of the shaft in an initial position.
  • the distance covered by the pivot lever during the corresponding adjustment of the pivot joint is also referred to as the release path.
  • the shaft and / or the ring can have at least two, in particular have at least three, preferably at least four, cams.
  • the shaft and / or the ring can have at least two, in particular have at least three, preferably at least four, cams.
  • the same advantages can result if, as an alternative or in addition, at least two, in particular at least three, preferably at least four, clamping elements and / or spring elements are provided.

  • the adjustment range available for the actual setting of the pivot lever 3 or functional part is smaller than the adjustment range between the starting position and the end position.
  • a so-called release path of the pivot lever 3 is provided, which is not the setting of the pivot lever 3 or the functional part, but the adjustment of the Swivel joint 1 is used from the setting position to the reset position and back again.
  • the pivot lever 3 can only be adjusted as required in the direction of the setting direction E. In the return direction R, this is not possible or only possible to a very limited extent.

  • the ring 6 together with the clamping elements 14 can rotate somewhat to the right, but only so far until the cams 15 of the ring 6 come into contact with the cams 17 of the shaft 7. Since the assembly lever 2 connected to the shaft 7 is not pivoted, the shaft 7 remains in its position and thus also holds the ring 6 more or less in its position. In this way, the pivoting lever 3 ultimately reaches the position which the user of the piece of furniture perceives to be comfortable.
