Definitions

  • Arramvsr This invention relates to improvements in convertible sitting and bed furniture, convertible couch beds being an important embodiment of the invention, and is a continuation in part of my co-pending application, Serial No. 165,240, filed May 31, 1950.
  • One feature of the invention is the construction of a convertible arm chair that comprises three readily separable pieces, viz.:
  • the couch bed unit (of greater length thanthe width of the arm chair) comprises four such pieces that include two separate bed-forming seat sections that are in side-by-side relation in couch use.
  • the track unit for the couch bed has a horizontal longitudinal track section resting on the floor and unitarily therewith one transverse track section (likewise resting on the floor), for each bed-forming seat unit.
  • Each seat unit has an arm rest and has a pair of support studs that ride or slide respectively along longitudinal and transverse Sections of the track unit when the arm rest is moved in States Patent an arcuate path relative to the back to a limiting position in which the arm rest is parallel to the back.
  • the seat section which consists of two superposed bed ele-' ments may be extended, the upper of the bed elements that carries the arm rest of the couch being slidable along a trackway formed in the lower of said sections to a limiting position for forming a full length bed.
  • Antifriction supports such as casters support the outer portion of the seat section and the outer portion of the extended section when drawn outward to form he bed.
  • the seat section of the arm chair or either or both seat sections of the couch unit may be displaced as such by riding at one end along the respective track sections with the casters at the other end riding on the floor, in the arcuate displacement of one or both arm rests as the case may be to position parallel to the back rest or to any desired oblique position between the normal position of the arm rest and the extreme position in which it extends parallel to the back.
  • the seat section may then be extended to a full length bed; and such extension is also possible without displacing the arm rest to an angle relative to the back by simply pulling it outward longitudinally of the couch bed or of the width of the chair. 5

  • the numeral 5 designates a rigid trackway for the shiftable support of seat sections, indicated as a whole by the numeral 6.
  • the trackway 5 has been here illustrated as being fabricated from a plurality of sections of channel irons, although it will be apparent that other forms of rigid trackways may be employed, and the invention is not restricted to the precise method of forming the track.
  • the trackway 5 includes a pair of straight tracks 7 having channels 8 to be traversed by a connecting guide device formed on the seat frames, to be hereinafter described.
  • the tracks 7 each form a relatively long trackway that is rigidly connected at their outer ends with an angle iron 9, welded or otherwise connected thereto.
  • the angle irons 9 are inwardly and forwardly angled as at 10 with the angle 10 extending inwardly substantially 45 degrees from the angle 9. Angle irons 9 and 10 constitute a floor support for the trackway.
  • each track section 11 comprises a forwardly extending straight portion 12 that is rigidly welded or otherwise connected to the tracks 7, the portions 12 thus being parallel.
  • the track sections 11 from the portions 12, are acutely angled outwardly from the portion 12 toward the respective ends of the trackway, as at 11 while the outer end of each track section 11 is reversely angled inwardly, as at 11, for a purpose to be presently described.
  • the trackway including the tracks 7 and 11, are disposed in an identical horizontal plane.
  • the rear end of each of the angles 9 is provided with a rigid perpendicular tubular leg 13 to form a connecting means between the track structure and rigid tubular posts 14 (Fig. 9), forming a part of the frame of the back rest 15.
  • a rigid perpendicular tubular leg 13 to form a connecting means between the track structure and rigid tubular posts 14 (Fig. 9), forming a part of the frame of the back rest 15.
  • the back rest 15 extends forwardly to partially overlie the mechanism of the trackway and extends somewhat beyond the opposite ends of the trackway.
  • the legs 13 telescopically receive the posts 14, whereby the back rest is rigidly supported in the elevated position against shifting and may be conveniently removed by lifting upwardly.
  • each seat section embodies a base frame member indicated as a whole by the numeral 16 and a companion over-riding seat frame indicated as a whole by the numeral 17.
  • Each of frame 16 is provided with legs 20 and 21.
  • the legs 21 are suitably connected together at their lower ends by an angle iron 22.
  • the end of the frame as defined by the legs 21 and angle iron 22 may be suitably transversely braced against flexing.
  • each track 23 Rigidly connected with the legs 20 and 21 at each side of the frame 16 are horizontally disposed tracks 23, the opposite ends of each track being inclined downwardly, as at 24, to their points of connection with the legs 20 and 21.
  • the intermediate section of each track 23 is downwardly spaced from and parallel with the side angles 18.
  • the frame 16 is ground supported at one end by casters 25 connected with the angle iron 22.
  • the opposite end of the frame 16 is shiftably supported upon the trackway 5 by a rigid and angularly disposed bar 26 having its terminal ends upturned and welded or otherwise connected to the angle iron 19 and one track 23 respectively, as clearly shown.
  • the bar 26 is provided with rigid depending pins 27 and 23 for riding engagement in the track groove 8 and the groove of the track section 11 respectively in a manner to be presently described.
  • the angle irons 18 are provided with spaced apart apertures throughout their length for the connection with suitable spring devices, (not shown).
  • the over-riding and extensible seat frame 17 is defined by a pair of parallel side angles 29 connected at its leading end by an angle 31 At their opposite ends, the angles 29 are provided with rigid outwardly disposed flat plates 31, connected at assembly by a cross bar 32.
  • the frames 16 and 17 is generally rectangular in top plan nected at one end by an angle 19. Each corner of the The bar 32 is provided adjacent each end with a roller 33. Since the frame 17 must have shiftable over-riding engagement with the frame 16, it is essential that during the over-riding shifting movement of the frame 17, adequate clearance be provided for the spring assembly of the frames and at assembly the frame 17 is engaged over the frame 16 prior to the installation of the bar 32 and its rollers 33, whereby the bar will extend transversely through the frame 16 to dispose the rollers 33 in contact with the upper surface of the tracks 23. Since the bar 32, as clearly shown, will underlie the angles 18 and overlie the tracks 23, the inner end of the frame 17 will be prevented from disengagement with the frame 16.
  • the bar 32 at assembly is rigidly connected to the side plates 31 in any convenient manner.
  • the forward end of the frame 17 is provided with rigid legs 34 and these legs 34 at their lower ends carry rollers 35 to facilitate axial shifting movement of the frame 17 with respect to the frame 16.
  • An upholstered arm rest 36 of any desirable construction is connected with the legs 34 in a convenient manner.
  • the vertical flanges of the angle irons 29 have sliding engagement with angle irons 18 through the medium of which the frame 17 is extended and prevented from laterally shifting movement.
  • the incline sections 24 of the tracks 23 permit the frame 17 to drop downwardly at either extremity of movement so as to properly position the frame 17 in its fully retracted and fully extended position with respect to the angles 18.
  • each angle 29 at its forward end adjacent the angle 30 is provided with rigid wedge blocks 37 that maintain the forward end of the frame 17 at a sufficient elevation that facilitates the movement of the frame 17 when starting its initial shifting movement to the extended position.
  • the sides of the frame 17 will be suitably covered and upholstered in a conventional manner in accordance with the upholstering of the back rest 15 and the arm rests 36.
  • the vertical flanges of the inner ends of each seat section 6 are in abuttingcngagee ment..
  • the upholstered forward corners of theseat' sec'-' tions would in the absence of other precautions have a rubbing contact during the initial swinging movement which would result in the upholstery soonsbecomingworn and ragged at this point.
  • the track sections 11 have been: angled inwardly at their outer ends as at 11 to control the move-v ment of the pin 28 in its respective groove. With the pins 27 and 28 engaging the grooves of the trackway 7 and 11, respectively, it will be found. thatwhen the operator grasps the arm rest 36' and starts the-outward swing:
  • Suitable stops 7' are positioned in the track groove 8 to limit the maximum shifting movement of the pin 27 to position the seat section in an accurate parallel position with respect to the back rest'and a suitable stop 11 limits the movement of the pin 28 rearwardly to dis pose the seat section at a right angle to the back 15. It will be apparent that the seat section may be shifted to any desired angularity with respect to the back rest for forming angle seats, similar to that illustrated in Figure 3.
  • Each seat section supports a two-part cushion pad 38; embodying pad sections 39 that are connected together by a transversely stitched fabric strip 40. While the strip is shown as of a single section that is permanently connected to the opposite pad sections 39, it may be found desirable to form this strip 40 in two sections to be connected together by a well known separable slide fastener, thus readily permitting the separation of the pads for replacement or recovering in the event of damage.
  • Pad sections 39 are preferably formed of foam rubber or the like and are adapted to be folded one upon the other to form'a double pad when the device'is inthe seat forming position of Figure 1, or to be unfolded one from the other to be co-extensive with the frames 16 and 17 when in the extended position.
  • the pad sections 39 when in the folded position are wholly supported upon the spring devices of the frame 17, and when the frame 17 has been shifted to the extended position, the pad is unfolded to extend over the spring devices of the frame 16 as well to form in effect a full length sleeping bed.
  • the fabric section 40 isformedsufficiently narrow so that when the sections 39 are unfolded, the abutting ends of the sections will be compressed to the extent that an objectionable joint in the mattress will be eliminated.
  • the tracks 11, adjacent the outer angled sections 11* are provided with inwardly extending semispherical abutments 41 that lie in the path of forward movement of the pins 28.
  • the seat sections In order for the seat sections to be shifted forwardly, sufficient pressure must be exerted by the operator to cause the pins 28 to first over-ride the abutments.
  • the seat sections are held firmly in their seat forming position under normal usage.
  • the frame members 16 and 17 are assembled as previously. described with the rollers 33 disposed on the tracks 23 and with the plates 31 and the vertical flanges of the angles 29 overlying the sides of the frame 16 with just sufficient clearance'to permit a freely sliding movement of the frame 17 with respect-to the frame 16.
  • the pins27and 28 are enga'ged within the grooves of their respective tracks.
  • the operator desires-to form a' bed, he grasps the arm rest-36 ofone-seat section shifting it forwardly in a horizontal are, causingithe pin-28 to first over-ride the abutment 41"a-nd then-to ride forwardly in the groove of the track section 11 to space the abutting ends of the seat sections. fromeach: other.
  • 'A continued forward arcuate movement causes the pin '27 to traverse its groove 8 while the pin 28 rides rearwardly in its respective groove of the track 11 in a reverse movement.
  • the frame 17 is supported by the rollers 33 and 35 throughout its continued outward movement.
  • the frame 17 is limited in its outward movement by the abutment of the bar32 with the legs 21.
  • theoperator then proceeds to unfold the pads 39 to fully overlie both the frames 16 and 17.

  • the outer ends of the track sections 43 are rigidly connected to a preferably angle iron frame member 45 that embodies a rearward extension 46 that rigidly carries a perpendicular post 47 adjacent its end.
  • the post 47 constitutes the detachable supporting means for the back section 15, and corresponds generally to the members 13.
