V

v IPIhe arm'nrest parttl6-t is similarly.:constructed and/has a. raised rear poz'ftion.1'6'.and foot members-37. and 38 serving to support the .arm rest.member when .in an upright position andtassembled. Thelinner walllboard of- .the'rsiderest member 16 also has transverselyextendiug boardlbra'ckets .guide tracks for the bed members and a togglbr acket forvthe' back rest. .The-bottonibracelboarid 17 is connected by means of screws between angle brackets 41 and 42 extending along the lower edges of the respective side arm parts and 16, Fig. 10.

The transverse brace board 13 is secured by screws between angle brackets 43 and -34 secured respectively to the respective arm rest parts 15 and 16. The transverse back board 19 is connected between angle brackets 45 and 46 on the respective arm rest parts 15 and 16. These transverse boards are all fastened by screws to the angle brackets and serve to hold the arm rest parts against lateral displacement and to maintain the form of the sofa. On the upwardly extending rear portions 15 and 16' of the arm rest parts are respective brackets 47, only one being shown to support the top board 20 to which the back rest is hinged by hinges 48.

The bed spring member 23 comprises a front frame piece 50 to the opposite ends of which there is connected respectively end frame members 51 and 52. Between the end frame members 51 and 52 there extend bed spring members 53 having their ends connected by tension springs 54 to the end frame members 51 and 52. Depending from the front frame member 50 and at the respective opposite ends thereof are respective legs 55 and 56 having respectively Wheels 57 and 58 adapted to roll over the floor as the bed is withdrawn or retracted. The rollers or wheels 57 are journalled respectively upon axles 59 and 60 extending through the lower ends of the legs 55 and 56 and through depending brackets 61 and 62 respectively associated with the respective legs 55 and 56. These wheels 57 and 58 preferably have rubber tires 63.

At the rear of the bed spring member 23 is a transversely extending pipe 64. The ends of this pipe are connected to the lower ends of depending brackets respectively connected to the end frame pieces 51 and 52. The pipe 64 is braced with the respective brackets 65 by diagonally extending braces 66, Fig. 7. It will be seen that the pipe 64 which connects with the bed spring member end frame pieces 51 and 52 is dropped to a location where it will not interfere with the user of the bed. The bed spring member 23 is thus made rigid without the rear frame member 64 being in the way.

The bed spring member 22 is similarly constructed and comprises end frame members between which are connected a plurality of bed spring assemblies 71 and a rear angle frame member 72, Fig. 7. The respective end frame members 70 of the bed spring member 22 are respectively connected by hinges 73 with the respective end frame members 51 and 52 of the bed spring member 23.

Pivoted respectively to the respective forward ends of the frame members 70 of the bed spring member 22 are pivotal brackets 74 between the lower ends of which are rigidly connected a dropped frame pipe piece 75, serving to brace the front of the bed spring member 22. It will thus be seen that by this means the brace pipe 75 will be retained out of the way of the user of the bed. Connecting links 76 respectively connect together the brackets 65 and 74 whereby to retain the pivotal brackets 74 in vertical parallel positions and the frame pipe 75 always under the bed spring member 22.

It will now be seen that the bed spring members 22 and 23 are hingedly connected together and that the bed spring member 22 can be hinged upwardly so as to be located in the back of the sofa but which will be automatically hinged downwardly as the bed spring members are pulled outwardly of the sofa parts. It will be clear now that the bed spring member frame pipes 64 and 75 will always be in a position such that no cross bars or pipes will interfere with the full spring action of the bed and that the spring assemblies are free of the frame pipes and adapted for comfortable sleep.

Extending inwardly from the arm rest parts 15 and 16 are respective brackets 77 and 78 adapted to underlie respectively lugs 79 and 80 weldingly secured to the respective front legs 55 and 56 of the bed spring member 4 23. Upon lifting the ends of the combined sofa and bed the brackets 77 and 78 will engage with the respective lugs 79 and 80 so that the front edge of the bed spring member 23 will be supported as the arm rest parts are lifted whereby to keep the bed spring members from dropping downwardly on to transverse brace board 17.

On the respective end pieces 51 and 52 of the bed spring member 23 are respectively guide rollers 82 adapted to travel respectively over guide tracks 83 and 84 secured to the inner boards of the respective arm rest parts 15 and 16. The ends of the guide track 83 are turned down as indicated respectively at 85 and 86, Fig. 7. The ends guide track 84 are respectively turned down as indicated at 87 and 88. With the rollers 82 resting on the turned down ends 85 and 87, the bed spring members will be locked against outward movement from the sofa parts. Upon the rollers 82 being rolled down over the forward bent ends 86 and 88, the bed spring members will be held in their outwardly extended positions and against the rearward pull of a counterbalancing spring mechanism indicated generally at 90 and mounted on transverse brace board 18.

The counterbalancing mechanism comprises a heavy tension spring 91 which is anchored to a bracket 92 mounted on the front face of the board 18. A double pulley bracket 93 having pulleys 94 and 95 is mounted on the end of the board 18 adjacent the arm rest part 15, Fig. 10, and on the opposite end of the board 18 adjacent the arm rest member 16 is a single pulley bracket 96 having a pulley 97. A cable of wire rope 98 has its respective ends run through the respective pulleys 95 and 96 for connection with wheel axles 59 and 60 on the legs 55 and 56 of the bed spring member 23. The wire rope cable is doubled on itself and extended over pulley 94 and connected to the free end of heavy tension spring 91 in the manner as indicated at 99. With the counterbalancing mechanism arranged in this manner, an equal pull will be effected upon the opposite ends of the front bed spring member 23. The rollers 82 will be held against depending ends 86 and 88 of the side tracks 83 and 84 by the spring tension of the counterbalancing mechanism 90 and in order to relieve the front bed spring member 23, a slight pressure will be required to start the rollers 32 upwardly over the bent ends 86 and 88.

On the rear end of the bed spring member 22 are guide roller brackets which are upstanding 100, disposed respectively on the opposite frame pieces 70 and having respectively guide rollers 101. Extending in an inclined manner on the respective arm rest parts 15 and 16 and over the rear upstanding portions 15 and 16' thereof are respectively guide tracks 102 over which the guide rollers 101 will run. As the bed spring members are drawn outwardly, the guide roller 101 will roll down the guide track 182, Fig. 7, and will finally come into engagement with a guide bracket stop 183 located at the lower end of the guide track 182 and secured to the arm rest part. So that the bed spring member 22 will remain in a position for use as a bed part, there is a guide track 102 and a stop bracket 103 on each arm rest part.

The depending back rest 21 comprises a frame 105, Fig. 3, between the ends of which there are extended a plurality of spring assemblies 196 having tension springs 107 against which a cushion 108 may be pressed. In order to permit the back rest to be elevated, the same is hinged to the top plate or brace 20 and is held in either its lifted or lowered positions by an over-center toggle bracket mechanisms 168' secured to the opposite ends of the back rest 21 and connected respectively to the arm rest parts 15 and 16. Each of the over-center toggle brackets comprise an attaching member 109 that is fixed by screws 110, Figs. 3 and 4, to the arm rest part. The upper end of the attaching member has an inwardly bent end 111. The lower end of the attaching member 109 has a pivot pin 112 with a toggle link 113 pivotally con nected thereto. A toggle link 11-5 and a pull link 115 are pivotally connected to the toggle link 113 by a pivotal pin 116. The toggle link 114 is pivotally connected by a pin 117 to a bracket 118 that is fixed to the end of the back rest frame 105. The pull link 115 is connected by a tension spring 119 to the inwardly bent end 111 of the attaching member 109 to exert an over-center pressure upon the toggle pin 116 and the toggle links 113 and 114. On the respective arm rest parts and 16 are stop brackets 120 serving to prevent the back rest from outward movement beyond a position adequate enough to free the bed spring member and mattress from the back of the furniture piece. The pull link 115 will abut the stop bracket 120 to thereby limit the outward movement of the toggle mechanism and the back rest beyond its forward position. After the mattress 26 and the bed spring members 23 and 22 have been pulled out, the back rest 21 can be lowered to its original vertical position and the fabric cover 28 brought forwardly, as shown in Fig. 6, over the front board 27. This fabric can be folded under the bed when the bed is in use and thereafter when the mattress and bed spring members are returned by a slight push, as illustrated in Fig. 5, into the sofa parts. The back rest would be pulled out prior to this return of the mattress and bed spring members. The front board 27 is preferably cushioned and covered with fabric, as shown in the sectional views. A slight pres sure on the front board 27 causes the rollers 82 to ride up over the downwardly bend ends 86 and 88 of the respective to ride up over the downwardly bent ends 96 and 88 of the respective tracks 83 and 84 and the counterbalancing spring mechanism will automatically return the mattress and the bed spring members to their retracted positions within the sofa parts.

It will now be apparent that there has been provided a combined sofa and bed which has the simplest form of operationto convert the sofa into a full size bed or a full size bed to a sofa.

It shall also be apparent that the mattress will not have to be completely doubled up when stored in the sofa parts so that wear and tear upon the mattress is minimized.

It should also be apparent that the bed is so constructed that the adjacent frame pieces of the respective bed spring members are lowered so as to permit free and full spring action of the entire bed area. By merely detaching th; screws which hold the brace boards to the brackets of the arm rest members the furniture piece can be disassembled to allow its parts to be stored or the piece taken through a small-doorway.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
