Definitions

  • the invention relates to a fitting for convertible seating and reclining furniture, in particular with an elevated back part, a lever arrangement and a tension spring being firmly connected to the base frame, the seat and back part, the seat and back part being pivotable about a common pivot point .
  • Fittings for convertible seating and reclining furniture enable the seat and back sections to be swiveled into the horizontal position and vice versa. There are fittings with a theoretical fulcrum through which the seat and back parts can be pivoted against each other. A movement of the seat and back part from the normal position in the direction of the lying position as a result of a force directed backwards onto any part of the back part is prevented by locking lever arrangements.
  • DD-PS 213 831 There is a fitting according to the preamble of claim 1 known (DD-PS 213 831), which is connected to the back part, seat part and base frame by means of a lever arrangement, the locking device being fitted directly between the seat and back part.
  • a lever rod and a tension spring are arranged between the back part and the frame, which enables the back part to be braked when it is transformed into the lying position.
  • the axis of rotation is located in the seat width of the reclining sofa below the abutting edge between the seat and back section.
  • the change from the sitting to the lying position when the wall is flush is carried out in a predetermined angular range.
  • This fitting can only be used for a defined backrest height and only for the transformation from the sitting to the lying position without intermediate positions.
  • back parts of different heights model or series change
  • the lever and stop construction must be recalculated and the design changed, whereby the angle range must be redefined. Due to the different heights and the associated different proportions of mass, there are inevitably changed static forces that do not allow universal use of the fitting.
  • the seat part must be lifted and pivoted under constant force.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating a fitting for convertible seating and reclining furniture, in particular with an elevated back part, which can be used universally without design changes for different back part heights and adjustable in different back part positions while ensuring that it is flush with the wall is.
  • the lever assembly has a base plate with holes, a lever, a plate and support bracket and driving lever with tension springs
  • the support bracket is rotatably mounted in holes in the base plate and holes in the plate, the forces occurring during the transformation from one position to the other others added by the lever arrangement and the tension springs, so that easy and simple handling is reliably guaranteed. Due to the different locking points of a support bracket in relation to the base plate, it is possible to use different back part heights without design changes to the fitting by selecting the appropriate hole in the base plate. whereby at the same time not only the sitting and lying position but also intermediate positions of the back part can be adjusted. This fitting ensures that the back is flush with the wall in any position.
  • the fitting consists in a manner known per se of a base plate 4 fixedly arranged on the base frame 13, a lever 1 which is mounted on the seat frame 16, a plate 2 which is fastened to the backrest frame 17 and support brackets 5; 6, which have their upper pivot points in the plate 2 and whose lower pivot point lies on the base plate 4.
  • the angle between the seat and backrest part is determined by the lever 1 and a molded part 3 which is rotatably mounted on the plate 2 and acted upon by a spring 18, the lever 1 and the molded part 3 being positively supported against one another on their mutually opposing sides.
  • These sides of the lever 1 and the molded part 3 are provided with steps so that they are locked in two or more positions depending on the position of the seat part relative to the lying part.
  • the lever 1 and the plate 2 are rotatable with each other at the pivot point 19 and the plate 2 is by two support bracket 5; 6 movably connected to the base plate 4.
  • the pivot point 11 of the support bracket 6 is fixed on the base plate 4 regardless of the different heights of the back part.
  • the support bracket 5 are on the base plate 4 through the holes 9; 10; Assigned 12 pivot points formed. Depending on the back part height, the support bracket 5 in the associated hole 9; 10; 12 stored. For example, the borehole 12 for a low back part height, the borehole 9 for medium-high back parts and the borehole 10 are assigned to the variants shown in FIGS. 1 and 2 for excessive back parts.
  • a driver lever 8 provided with a stop 14 is movably fastened in the borehole 11.
  • One end of the driving lever 8 is designed such that the support bracket 6 strikes the stop 14 during its forward movement and thereby takes the driving lever 8 with it.
  • the tension spring 7 located between the one end of the driving lever 8 and the fastening point 15 is tensioned during the movement.
  • the transformation from the lying position into the sitting position or vice versa is maximally influenced by the spring-loaded driver lever 8. Only a small amount of force directed from the front towards the seat is necessary for this transformation phase.
  • the length of the tension spring 7 is dimensioned such that the driving lever 8 is vertical in the sitting position.
  • a driver lever 21, which is preferably mounted in the borehole 11 of the support bracket 6, has at its upper end a stop 22 designed like the stop 14 and a spring suspension 23 for the tension spring 20.
  • the other end of the tension spring 20 is fastened on the base plate 4. During the backward movement of the support bracket 6, this strikes the stop 22 of the driving lever 21 and takes it with it. As a result, the tension spring 20 is tensioned and thus produces a damping effect.
  • the seat part is pivoted in the existing seat position, so that the molded part 3 is changed over the lever 1 so that the inclination of the back part relative to the seat part changes according to the associated level of the lever 1 and the molded part 3 becomes.
