Fig. 6 is a fragmental detail of a portion of the lifting mechanism in collapsed position.
The couch bed consists essentially of a main bed section I and an extension bed section 2.
The main bed section preferably has a rear wall member 3, two side wall members 4 and 5 and a box spring 6 connected to one another with the front side of the bed section between the front edges of the side wall members 4 and 5 and the box spring 6 open to form the entrance for the extension bed section 2 which may with facility be housed within said main bed section beneath the box spring 6. The rear wall member 3 and side wall members 4 and 5 preferably are not mounted on rollers but on plain supporting members 1 preferably to cooperate with the floor or other supporting surface to resist movement when the extension bed section 2 is moved into and out of the main bed section I. On the box spring 6 of the main bed section I, there is supported the mattress 8 and in single bed formation on the rear end of the mattress 8, there may be mounted on end the pillows 9, l0 and H.
The extension bed section 2 is preferably composed of a lower frame l2 and an upper frame I3. The lower frame l2 consists essentially of two '40 side bars M and I5 composed of angle iron with their horizontal webs extending inwardly from the lower ends of their vertical webs and two end bars l6 and I! with their horizontal webs extending outwardly from the lower ends of their 5 vertical webs.
The upper frame l3 consists essentially of two side bars l8 and ill with their horizontal webs extending inwardly from the lower ends of their vertical webs and two end bars 20 and 2| with their horizontal webs extending inwardly from the upper ends of their vertical webs.
The spring elements 22 and 23 forming the fiat spring of the upper frame between the horizontally extending webs of the side bars l8 and I 9 and end bars 20 and 2| are preferably connected to such horizontally extending webs as shown in Fig. 2. In collapsed or descended position of the upper frame I3, the horizontally extending webs of the end bars 26 and 2| may be disposed above the edges of the vertically extending webs of the end bars I6 and ll of the lower frame I2 and the vertically extending webs of the end bars 20 and 2| extend down outside of the vertically extending webs of the end bars I6 and I! as shown more clearly in Fig. 6.
The end bars I6 and I! are each preferably connected to one of the end bars 26 and 2| by a pair of collapsible flat links consisting essentially of a long link 24 and a short link 25 for the end bars I6 and 26 and of the long link 26 a'nd short link 21 for the end bars I! and 2|. One end of the long link 24 is pivotally connected to the outside of the vertically extending web of the end bar I6 and the other end of such link 24 disposed to the inside of the vertically extending Web of the end bar 20, provided with a pin 28 slidably mounted in the slot 29 of the vertically extending web of the bar 20, and the link 25 is preferably pivoted to the outer face of the intermediate portion of the link 24 at one end and to the inner face of the vertically extending web of the end bar 26 at its other end. The long link 26 is similarly connected to the end bars I? and 2| and the short link 21 to the long link 26 and end bar 2|. The long links 24 and 26 are preferably parallel to one another and the short links 25 and 2Ialso parallel to one another.
The side bars I4 and I5 are each preferably connected to one of the side bars I8 and I9 by a set of collapsible flat links consisting of the links 30, 3| and 32 for the side bars I4 and I8 and of the links 33, 34 and 35 for the side bars I5 and I9. The links 30 and 32 are preferably parallel to one another and pivotally connected at their lower ends to the outer face of the vertically extending web of the side bar I4 and extend to the outer face of the vertically extending web of the side bar I8 and are there provided with pins 36 and 31 respectively slidably mounted in the longitudinally extending slots I40 and MI formed in the vertically extending web of the side bar I8.
The link 3| is preferably pivotally connected to the intermediate outer face of the link 36 at its lower end and pivotally connected to the outer face of the vertically extending web of the side bar I8 at its upper end.
The links 33 and 35, see particularly Fig. 4, are preferably parallel to one another and operatively connected to the side bars I5 and I9 similar to the manner in which the links 30 and 32 are connected to the side bars I4 and I8. The
lower ends ofthe links 33 and 35 are pivotally connected to the outer face of the vertically extending web of the side bar I5 and the upper ends of such links extend to the outer face of the vertically extending web of the side bar I9 and .are there provided with the pins 38 and 39 slidably mounted in the longitudinally extending slots 46 and 4| formed in the vertically extending webof the side bar I9. The link 34 is pivotally connected to the outer intermediate face of the link 33 at its lower end and at its upper end to the outer face of the vertically extending web o f the side barI9.
The links 36 and'33 are preferably parallel to one another, so are the links 3| and 34, also the links 32 and 35, also the links 24 and 26 and also the links 25 and 21 all in the interest of the side bars I8 and I9 respectively at a distance from the ends of the side bars I8 and. I9 substantially equal to the length of a short arm 46, 41. The long arm portions 44 and 45 are preferably connected to one another by two cross rods 48 and 49 which cooperate with the arm portions 44 and 45 in forming a head board for the extension bed section or a support for a pillow or the like in open bed formation or as an anchor for engaging the upper face of the mattress 59 supported on the fiat spring of the upper frame I3 in collapsed or lowered position.
The pins 3'! and 39 on the outside of the links 32 and 35 are pivotally connected to the lower ends of the links 5| and 52 respectively. The upper ends of the links 5| and 52 are pivotally connected with the outer faces of the bent levers 42 and 43 respectively at the junctures between their long and short arm portions. The pins 3! and 39 are further pivotally connected to the ends of the links 53 and 54' respectively extending along the inner faces of the vertically extending Web portions of the side bars I8 and I9. The other ends of the links 53 and 54 are pivotally connected to the pins 36 and 38 respectively. The'links 53 and 54 are preferably parallel as shown.
From the foregoing, it will be seen that the actuation of the long arm portions 44 and 45 toward the upper face of the mattress 56 will cause the upper frame I3 to descend into the position shown in Figs. '1, 2, 3 and 6 and that the actuation of such arm portions 44 and 45 away from theupper face of the mattress 56 into erect position will cause the upper frame I3 to rise into position shown in Figs. 4 and 5.
To facilitate actuation of the upper frame I3 into raised position and furthermore to anchor the same in its uppermost position, the springs 54 and 55 are provided, the spring 54 being connected at one end to the pin 56 extending inwardly from the intermediate portion of the.
In the interest of simplifying the construction, the projections 5'! and 59 are formed as the upward extensions of the roller brackets 69 and 6| respectively of the casters 62 and 63 respectively. The side bar I6 of the lower frame I2 is also provided with casters, to wit the casters 64 and 65 journaled in the brackets 66 and 6'! respectively connected to the inner face of the upwardly extending web of the side bar I6.
To form limiting stops for the bent levers 42 and 43 in their erect positon, the ends of the end bar 2| preferably extend beyo'ndthe side bars I8 and I9 to form an abutment for the '75 lower faces of the short arm portions 46 and 47 as shown in Fig. 4.
To form limiting stops for the extension bed section 2 when normally moved into double bed formation, the end bars l6 and I! are provided with plates 68 and 69 having the downwardly extending lips H3 and II respectively to engage the inwardly extending projections 12 and 13 formed on the lower ends of the front edges of the side wall members 4 and 5.
To form a neat closure for the opening between the front edges of the side wall members 4 and 5 and box spring 6 when the extension bed section 2 is disposed within the chamber formed beneath the box spring 6 of the main bed section I, the closure board 14 is provided secured to the front faces of the upwardly extending arms 15 of the supporting brackets 16.
It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
