Definitions

  • My present invention relates to improvements in frames for couches, cots, lounges, divans, settees, convertibles, chaise longues and similar places of rest.
  • the improved frame disclosed by my invention comprises a batten grate or lath grate forming a place of rest, which grate comprises a plurality of flexible crosslaths consisting of glued wooden battens and being supported at their ends.
  • the supporting means for said laths are made springy so that they resiliently yield both in the vertical and horizontal directions.
  • the crosslaths form or define a surface of rest which is adaptable to the body contours of the recumbent person.
  • FIG. 1 shows the couch frame in perspective view
  • FIG. 2 is a perspective view of a section of the frame in a larger scale
  • FIG. 3 is a cross-section of FIG. 2 in a plane passing through a crosslath
  • FIG. 4 is a cross-section through the lath grate under load of the weight of a recumbent person.
  • the frame shown in FIG. 1 comprises a base 1 to which is hinged a headrest 2 which is lockable in various positions of inclination. Between the longitudinal sleepers of frame 1 are arranged crosslaths 3 made of laminated and glued wooden elements. These laths 3 together form a lath grate and are resiliently mounted at both their ends. To such end, the two longitudinal sleepers of base 1 are made wavy on top, and their wave crests form a series of points of support 1 (FIG. 2) to which is secured a longitudinal elastic bearing and anchoring strip 4 of U-shaped cross-section which may be made of rubber for example.
  • the crosslaths 3 which are prestressed by being bent or deflected upwardly, have their ends engaged in the two rubber strips 4 intermediate of the points 1 of the longitudinal base sleepers to which said strips are fixed by means of screws 5 for example.
  • the bearing strips 4 may be resiliently deflected downwardly or depressed at the points of bearing of the crosslath-ends between two wave-crests of the longitudinal base sleepers.
  • the crosslaths themselves thus are mounted resiliently both in the vertical and horizontal positions of support and thereby form a place of rest which is capable of adapting itself to the body of a recumbent person, as indicated in FIG. 4. Furthermore, bothersome creaking and squeaking is avoided such as is produced when wood contacts wood under load.
  • a couch frame comprising, in combination, a pair of substantially parallel relatively elongated and fixed side rails having relatively wide vertical surfaces and relatively narrow substantially horizontal upper and lower edges, the upper edge of each side rail undulating in a vertical direction throughout at least the major part of its length along a substantially regular curve having longitudinally spaced convexly curved crests alternating with concavely curved troughs, the respective crests and troughs of the two side rails being laterally aligned; a pair of relatively elongated substantially fiat strips of elastic material each extending along the upper edge of a respective side rail, each strip normally lying in a substantially horizontal plane and being tangent to the crests of its associated side rail upper edge and secured to said crests; and a plurality of longitudinally spaced laterally extending cross-slats each connected at its opposite ends to said strips substantially midway between longitudinally adjacent points at which the strips are attached to the associated crests.
  • each of said resilient strips comprises a longitudinally extending member folded about a longitudinally extending medial line around the ends of said cross-slats.
  • a couch frame as claimed in claim 1, wherein said cross-slats are upwardly convex between their opposite ends.
  • each cross-slat is a laminated wood structure prestressed to curve convexly upwardly between its opposite ends.
  • a couch frame as claimed in claim 1, including a back rest hingedly connected to said side rails adjacent one end thereof and adjustably positionable between substantially horizontal and substantially vertical positions.
