Definitions

  • ABSTRACT A seatingand sleeping-furniture piece, which comprises a framework and a cushion swingably mounted on the framework.
  • the cushion is adapted to form in a seating furniture a backrest in its backward up Mar. 26, 1974 wardly swung position, and to form in a sleeping furniture a wedge cushion in its downwardly swung position.
  • Two cushions are disposed on a carriage capable of rolling-in into and rolling-out from the framework.
  • the cushions are disposed on top of each other in the seating furniture and during their rolling out and under-grip in the seating position the cushion swung upwardly as a backrest and rolling out so far in the one bed position under the cushion swung upwardly as a backrest, that the forward bottom edge of the backrest and the rear edge of the seatingand the layingcushion are disposed vertically on top of each other, and in the double bed position, the two seatingand laying-cushions are disposed one behind the other, and capable of being laid down in the double bed position following the cushion swung forward downwardly as a wedge cushion with the formation of a double layving face.
  • the carriage comprises two telescope-like parts displaceable relative to each other.
  • the inside disposed of the parts defines a bedding chamber, which has an engagement face for the upper of the seating cushions in its use as laying cushion, as well as have an engagement face for the wedge cushion, and is supported on the floor.
  • the outside disposed part is supported on the floor on the front and at the rear by means of rollers on the inside disposed part, and forms an engagement face for the lower seatingand layingcushion.
  • a cover receives a wire insert to form an upper closure for the bedding chamber, and is swingably mounted in a frame.
  • the frame is swingably mounted on the inner part of the carriage and is equipped with slide pins.
  • the framework includes obliquely rearwardly disposed grooves which secure the slide pins.
  • Roller means are formed on the outer part of the carriage, and side parts of the frame are formed as sliding faces for the roller.
  • the present invention relates to a seatingand sleeping furniture piece useable as a single or double bed.
  • a seatingand sleeping-furniture piece has been known in the Austrian Pat. No. 230,570, in which a cushion is swingably mounted on a frame, which cushion forms in the seating-furniture piece a back rest in its swung-up position and in the sleeping-furniture piece a wedge cushion in its downwardly swung position and in which two cushions are provided on a carriage capable of rolling inwardly and outwardly, respectively, relative to the framework.
  • the two cushions are superposed in the seating-furniture piece and during rolling out of the carriage and undergrip the cushion swung upwardly as a backrest and in the single bed position are rolled out so far below the cushion swung upwardly as a backrest, that the forward edge of the backrest and the rear edge of the seatingand lyingcushions, respectively, are vertically on top of each other, and in the double-bed position the two seatingand lying-cushions, respectively, are arranged one behind the other and capable of being laid, following the cushion swung downwardly as a wedge cushion, with the formation of a double laying face.
  • the carriage consists thereby of two parts telescopically displaceable relative to each other, the inwardly disposed part forming a bedding chamber, having a supporting face for the upper seating cushion and being supported itself on the floor, while the outwardly disposed part is sup ported at the front on the floor and at its rear by means of rollers on the inwardly disposed floor, and forms a supporting face for the lower seatingand layingcushion.
  • This oblique inclination is to be removed again, however, during the transformation of the seating-furniture piece into a sleeping-furniture piece and is formed as a plane and horizontal laying face.
  • the cushion finding use as a wedge cushion can be brought into any obliqueor inclined-position, yet also into a horizontal position.
  • the support of the cushion is to be performed such, that no impressions result on its upholstery.
  • the cushion forming in the seating position a backrest and in the sleeping position a wedge cushion is to maintain at first its position during the transformation from the seating position into the sleeping position that means is not to tip downwardly, before swinging it down manually.
  • the upward swinging of the cushion from its position as a wedge cushion into its position as a backrest is to be simplified.
  • walls of flexible material by example textile material or synthetic material, is provided as a rear and lateral closure of the bedding chamber.
  • a seatingand sleeping-furniture piece which includes a swivel-bearing connected with the framework for adjustment of height provided for the swingable mounting of the backrest or wedge cushion, respectively.
  • the swivel-bearing has, in accordance with the present invention, a bearing pin flattened at least on one side, which is yieldingly supported, by example on a blade spring.
  • the blade spring can be secured thereby in slots of bearing blocks, which are connected with the framework for adjustment of their height or it may have seats for its securing by screws to bearing blocks connected with the framework for adjustment of their heights.
  • the blade spring which cooperates with the flattened part of the bearing pin, that the backrest tips downwardly, as soon as the seatingor laying-cushion cannot support it any more, rather can be swung downwardly only by manual operation. Furthermore, it is brought aboutby the yielding support of the bearing pin by a blade spring, that the backrest sinks slightly downwardly, as soon as the seatingor laying-cushions are pulled out under it and thereby prevents a rearward sliding of the carriage.
  • the blade spring supports the upward swinging of the wedge cushion into its position as a backrest.
  • connection of the swivel bearing for the backrest or wedge cushion, respectively, which connection is adjustable as to its height, provides also the possibility for variation of the inclined position of the wedge cushion, in particular to achieve, that the wedge cushion assumes a horizontal position in the bed position.
  • an abutment is provided laterally on the backrest or the wedge cushion and preferably adjustable counter abutments are provided on the inside of the framework.
  • joint bars are provided laterally on the backrestor wedge cushion, respectively, for the swingable mounting of the latter, which joint bars are pivotally on the inside of the framework and have outwardly directed projections, by example throws, which enter bowshaped recesses on the inside of the framework, the ends of which are formed as abutments for the projections for securing the use positions of the cushion as a backrest or as a wedge cushion, respectively.
  • Adjustable abutments can be provided thereby at the ends of the bow-shaped recesses.

  • the bearing pin 3 of the cushion 2 is, as shown in FIGS. 5 and 6, flattened at least on one side and it supports itself on a blade spring 20. By this type of support, it is brought about at first, that the backrest remains in the position shown in FIGS. 1 to 3, even if the seating and laying cushions 4 and 5 are pulled out thereunder. Furthermore, in the position of the furniture piece, shown in FIG.
  • the cushion 2 sinks slightly downwardly with a bending through of the blade spring 2, when its bottom forward edge losses its support by the upper cushion 4.
