Abstract
508,355. Bed-settees &c. NILSSON, J. E., and FRECH, C. March 14, 1938, No. 32202. Divided out of 503,277. [Class 52 (ii)] A chair convertible into a bed comprises a main frame within which are vertical slidable rigid legs, an extension section pivoted to the main frame and carrying leg-operating means which remain stationary while the.extension section is swung over to a predetermined amount, the axis of rotation of the extension section then becoming automatically transferred to another axis and causing the slidable legs to be projected and the main frame to rise. Figs. 3 and 6 show a chair-bedstead in which the main frame comprises a pair of boxes 2 carrying a wire mattress 4 between them and having guides 46 for the legs 21. The extension section comprises arms 6, back 7, a seat 9 supported on a wire mattress 8 extending between side boxes 10 the upper ends of which are enclosed in the arms 6. The boxes 10 may enclose front legs as described in Specification 503,277. The main frame and extension section are connected together by bars 11 which are hinged to the boxes 2 at 12 and to the boxes 10 at 13. When the extension section is first swung over it rotates about the hinges 13 without affecting the legs 21. Further rotation of the extension section causes lugs 58 thereon to abut against the bars 11 and these with the extension section then rotate as a whole about the hinges 12. The rotation of the bars 11 causes the main frame to rise and the legs 21 to be projected through the bottom of the main frame. In the construction shown in Figs. 3 and 6, the operating bars 11 1 are connected to the legs 21 by linkwork aided by springs 55, 56. Figs. 7 and 8 show a construction in which cables and linkwork in the form of lazy-tongs are used for actuating the legs 21. The link 60 is pivoted to the lower end of the bar 11 and the pivot 61 is mounted on a slider 62 which can move along a slideway 63 under the action of a spring 64 fixed to a second slider 65 which is connected to the. slider 62 by flexible wire cables 66. The outer end of the lazy-tongs carries a roller 67 around which passes a cable 68 which is also wrapped round pulleys 69, 70 and is connected at its ends to a bar 57 fixed to the legs 21. When. the bar 11 is rotated about its pivot 12 by the lug 58 the lazy-tongs is extended, taking with it the roller 67 and shortening the vertical lengths of the cable 68 attached to the bar 57 and thus extending the legs 21 below the main frame of the bed. Figs. '11 and 14 show a further modification in which chain-gearing racks and pinions are used for extending the legs 21 below the main frame. The bar 11 is connected to a chain 71 which moves over guides 72 and idle sprocket wheels 73 and rotates a sprocket 75 on the spindle of which is a toothed wheel which transmits motion through other wheels to a shaft 83. Rotation of the shaft 83 causes rotation of spur .wheels 87, 88 which engage racks 89, 90 provided on the legs 21. A spring 91 assists the rotation of the shaft 83 when the bed is being folded to form a chair.
