Definitions

  • the invention relates to a piece of seating or reclining furniture with a furniture frame in which at least one trolley can be extended, which is provided with upholstery and which forms a lying surface in its extended position, the trolley having at least one pulling and pushing element a motor drive arranged expediently in the furniture frame is connected so that it can be moved in and out by motor.
  • a piece of furniture of this type has become known from USA-A-2 834 969, in which the carriage can be moved in and out via chain drives which are each guided over two chain wheels.
  • the arrangement of these chain drives is relatively complicated, and the furniture for these chain drives must be specially designed.
  • the invention has set itself the goal of creating a seating or reclining furniture, the car can be moved in and out safely and relatively easily by motor, the installation in a piece of furniture should be simple.
  • Such a link chain known per se can be accommodated in a space-saving manner by pivoting the links in the unlocked direction, whereas such a link chain can also be used as a pressure element if the links are prevented from moving in one free direction.
  • the carriage is connected to the furniture frame via a telescopic guide, expediently a ball extension, and supports for the limbs are arranged on the telescopic guide.
  • the chain links can be conveniently accommodated in the retracted position of the carriage if the links are pivotably guided in the furniture frame in a horizontal plane.
  • FIG. 1 shows a seating or reclining furniture of a first embodiment in a schematic top view, partially in section;
  • Figure 2 shows the link chain used in this embodiment in the area of the motor drive in view.
  • Fig. 3 shows a second embodiment in the sitting position.
  • a carriage 2 which is supported by wheels 3 on the floor, is arranged so that it can be extended in a furniture frame 1.
  • the connection of the carriage 2 to the furniture frame 1 takes place via a telescopic guide 4, which is expediently designed as a ball extension.
  • link chain 5 One end of a link chain 5 is rigidly connected to the carriage 2, the design of which can be seen in particular in FIG. 2. Accordingly, the individual links 6 of the link chain 5 are connected by means of bolts 7, so that they can be pivoted relative to one another. The pivoting toward one side, in FIG. 2 this is counterclockwise pivoting, but is limited by stops 8, 9 arranged on the links in such a way that at most essentially the stretched position of the link chain 5 is reached.
  • the pinion 11 is driven by a geared motor 12 arranged in the furniture frame 1.
  • a horizontally extending guide 13 into which the link chain 5 can be inserted.
  • supports 16 and 17 are arranged at such a distance that the link chain 5 cannot break out and sag between the supports.
  • the upholstery of the furniture frame 1 or of the carriage 2 is not shown for reasons of clarity, but is not essential to the invention, since all designs known for convertible furniture can be arranged.
  • a furniture frame 21 is provided with a padded head part 22, a middle frame 24 equipped with padding 23 and a carriage 26 equipped with padding 25.
  • a backrest 27 is firmly connected to the furniture frame 21.
  • the central frame 24 has two support feet 28 and 29 which are provided with rollers and are each arranged in the region of the ends of the central frame 24.
  • the support foot 28 is connected to a two-armed lever 30 and guided in or on two guides 31 and 32 which run essentially parallel to one another.
  • the guideway 31 is longer than the guideway 32 and is provided with an end stop 31 '.
  • the support foot 28 is pivotally mounted in the guideway 31 and has at its lower end a roller 32 'which runs on the guideway 32 over part of its path.
  • a push rod 33 is also articulated on the lever 30, the other end of which engages on the support foot 29 which can be pivoted about a pivot point 34.
  • a spring 35 endeavors to pivot the support foot 29 counterclockwise.
  • On the support foot 29 also engages a tab 36 which is connected at the other end to a push rod 37, the articulated connection of these two parts being guided in an elongated hole which is not shown for reasons of clarity.
  • the push rod 37 is in turn slidably guided in a guide 39 arranged on the carriage 26.
  • the carriage 26 has a foot 40 which can be swiveled between two positions, the seat cushion 25 lying obliquely in the sitting position shown in FIG. 3 and lying horizontally in the lying position not shown.
  • the carriage 26 is also guided over a roller 41 on the floor.
  • One end of the head part 22 is also articulated on the lever 30. A further support of the head part 22 takes place via a support rod 42.
  • a chain chain 5 is indicated by a dash-dotted line, one end of which engages at 43 on the carriage 26 and is arranged for the supports (not shown) corresponding to the supports 16, 17 according to FIG. 1.
  • the carriage 26 is rolled forward by means of the link chain 5 over the central frame 24.
  • the carriage 26 remains in the inclined position until the roller of the foot 40 is braked by a stop 44 and thereby the foot 40 is pivoted and the head-side part of the carriage 26 is raised.
  • the end of the push rod 37 slides in the guide 39 and initially remains in its approximately vertical position.
  • the middle frame 24 is taken along, the support feet 28 and 29 initially maintaining their pivoted position.
  • the support foot 28 swivels upwards in a clockwise direction and takes the support foot 29 with it via the push rod 33 also pulled out the head part 22 behind the backrest 27 while pivoting the support 42.
