Definitions

  • the invention relates to an adjustment device for setting a defined position of a leg rest of a piece of furniture that can be reversibly moved from a position of use into a non-use position and back via a legrest fitting, the legrest being held on a swivel arm of the legrest fitting that is pivotably connected to a frame.
  • the invention also relates to an adjustment element.
  • the legrest fitting for a legrest for seating and / or reclining furniture that can be reversibly moved from a position of use to a position of non-use and back is known.
  • the legrest fitting has a holding device.
  • the holding device comprises a holding body attached to a frame of the legrest fitting and a holding element which interacts with the holding body and is coupled to a legrest carrier of the legrest fitting.
  • the legrest In the non-use position, the legrest is held in an exactly defined position in that the holding body is held in a holding section of the holding element. Nevertheless, it is the case that the defined position of the legrest in relation to the frame or to the other components of the legrest fitting is not adjustable. Rather, the legrest is always kept in one and the same position in the non-use position.
  • the object of the present invention is therefore to provide a means which enables an adjustable, defined position of a leg support that is adjustably held on a leg support fitting.
  • the adjustment device comprises an adjustment element with a planar first contact surface and with a planar second contact surface parallel to the first contact surface, with a circumferential surface connecting the contact surfaces and with an elongated opening.
  • the circumferential surface has a first contact surface area which is in any case shaped in sections to correspond to the pivot arm and inclined in relation to a longitudinal axis of the opening.
  • the adjustment device further comprises a releasable connecting means, via which the adjustment element is adjustably held on the leg rest fitting. In a first assembly position of the adjustment element, the connecting means is fixed to the leg rest fitting and passed through the opening of the adjustment element.

  • the particular advantage of the invention is that the first contact surface area can be rotated or displaced by a rotational or translational adjustment of the adjustment element held in the assembly position, and the pivot arm applied to the first contact surface area when the legrest is not in use is adjusted accordingly.
  • an orientation of the legrest in relation to the frame of the legrest fitting can be adjusted in a simple manner.
  • the connecting means fixed on the leg rest fitting in the assembly position is preferably easy to release. In this way, the adjustment element can be rotated about a connecting means longitudinal axis of the connecting means or can be displaced translationally along the opening longitudinal axis of the opening.
  • the core idea of the invention consists in the fact that the adjustment element represents an adjustable swivel stop for at least one swivel arm of the swivel unit against which the swivel arm is placed in the non-use position of the legrest.
  • an adjustment of the adjustment element causes a corresponding pivoting of the swivel arm in the non-use position of the legrest, whereby a defined position of the legrest can be set in the non-use position.
  • the first contact surface area of the adjustment element in the first assembly position, is placed on the outside of a swivel arm end of the swivel arm opposite the leg rest and / or below a swivel axis provided in the swivel arm end, over which the swivel arm can be swiveled in relation to the frame of the leg rest fitting is held.

  • the connecting means is a screw or a threaded bolt, the adjustment element being fixed in the first assembly position and / or the second assembly position via a screw nut screwed onto the threaded bolt.
  • Such releasable connecting means are advantageously available as inexpensive and readily available standard components which can be assembled in a simple and known manner.
  • an adjustment element comprises two parallel, opposed, flat contact surfaces, a circumferential surface connecting the contact surfaces and an elongated opening, the circumferential surface having a first contact surface area inclined in relation to a longitudinal axis of the opening.
  • the first contact surface area is used Adjustment element as a swivel stop for at least one swivel arm of the legrest fitting in the non-use position of the legrest.
  • the opening of the adjustment element is provided for the passage of a connecting means by means of which the adjustment element can be fixed in the assembly position on the leg rest fitting. Furthermore, the adjustment element can be displaced translationally in a defined manner along the longitudinal axis of the elongated opening.
  • the contact surfaces are congruent.
  • the adjustment element can thus be manufactured particularly inexpensively.

  • the symmetry shape simplifies the assembly of the adjustment element and both the first contact surface area and the second contact surface area can function as a swivel stop against which the swivel arm is placed when the legrest is not in use.
  • an alternative development of the adjustment element according to the invention provides that the first contact surface area of the circumferential surface is oriented inclined to the longitudinal axis of the opening and that a second contact surface area opposite the first contact surface area, which is formed by the circumferential surface, is provided parallel to the first contact surface area.
  • contact surface areas that are rectilinear in cross-section in any case form a parallelogram-shaped adjustment element cross-section. This shape enables both the first contact surface area and the opposite, second contact surface area to function as a swivel stop for the swivel arm when the legrest is not in use.
  • the opening opens internally into the contact surfaces or the contact surfaces completely enclose the opening. It is provided that the opening has the shape of a completely bordered elongated hole. In this respect, an edge is formed between the opening formed as an elongated hole and the circumferential surface.

It is provided as a safety device, in particular in the event that when the legrest 6 is moved back from the position of use to the non-use position, there is an obstacle underneath the legrest 6 (blocking situation). In this case, the contact surface 55 first detaches from the deflecting element 61 and the auxiliary contact surface 58 then rests against the deflecting element 61. When the slide 30 of the displacement unit 5 moves back further, the auxiliary contact surface 58 functions as an auxiliary run-on bevel, along which the first pivot arm 22 has moved against the deflecting element 61. This way is a The pivoting unit 4 is forcibly swiveled down, which prevents the legrest 6 from moving against the seat cushion 66 and damage to the legrest fitting 2 or to the seating and / or reclining furniture 1.
