Specification of Letters Patent.

Patented June 1?, 1919.

Application filed July 8, 1915. Serial No. 38,656.

To all whom it may concern:

Be it known that I, GEORGE Fisonnurr, a citizen of the United States of America, and a resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Folding Beds, of which the following is a specification.

This invention relates to that" type of folding beds in which a series of bed-sections are pivotally connected together and to the main frame and are adapted to unfold outwardly from the said main frame, an example of which structure constitutes the subject matter of my prior Letters Patent No. 1,078,909, dated Nov. 18, 1913.

And the present improvement has for its object to provide a structural formation and association of parts, adapted to effect a balancing action. of the parts in their folding and unfolding movements, so that said movements may be effected with a minimum effort on the part of the operator, all as Will hereinafter more fully appear.

In the accompanying drawings Figure 1, 1s a longitudinal sectional elevation on line ccw Fig. 4, illustrating the present construction in a closed or folded condition.

Figs. 1 and 1 are companion detail perspective views of the duplex hinge connection between the main frame and the seat section of the bed, in the respective folded and unfolded condition of the parts.

Fig. 2, is alongitudinal sectional elevationillustrating the parts in a series of partly unfolded conditions.

Fig. 2 is a detail transverse sectional elevation on line m-w', Fig. 1, of the latching of the seat member of the bed.

Fig. 3, is a longitudinal sectional elevation, illustrating the parts in a fully unfolded condition.

Fig. 4, is a sectional plan view of one side of the bed, in an unfolded condition.

Similar reference numerals indicate like parts in the several views. Referring to the drawings, 1 designates the main frame of the present bed-structure of the usual. box form and provided with the usual transverse back frame 2 and end arms 3, and in the present structure said end arms 3, will have spaced relation to the adjacent parallel rails or members 41- of the main frame 1 to provide working spaces for the dliplex hinge members 5 by which the seat member 6 is pivotally connected to theforward end of the'base portion of the main frame 1 in a manner which imposes an outward longitudinal movement. on said seat member 6, simultaneous with its pivotal movement, to provide ample clearance of the surface tufting, etc., with which the parts are usually finished. With the seat member in its folded position, the aforesaid hinge members 5 are wholly within the main frame 1, and an objectionable projection of the same at the front of the. structure is avoided. To such end each duplex hinge member will comprise a detail construction, as follows 7 and 8 designate counterpart hinge bars associated in crossed relation and pivoted together at their midlengths, with one end of one hinge bar pivoted to the main frame 1, and. with one end of the companion hinge bar pivoted to the seat member 6.

9 and 10 designate radius links pivotally connecting the opposite ends of the hinge bars 7 and 8 with the main frame 1, and with the seat member 6, respectively. In the construction shown, the hinge bar 8, which is pivoted in a direct manner to the main frame 1, will be connected by the radius link 9 to the seat member 6; while the hinge bar 7 which is pivoted in a direct particularly in Figs. 1 and 1 and in addition the radius link 9 will have an angular or curved form as shown, so as to clear the adjacent pivot end of the hinge bar 7, in the folding and unfolding movement of the parts.

A material part of the present invention involves the pivotal attachment of the afore said link members 8 and 10 in an approximately horizontal line, to the main frame 1, as by such arrangement the vertical rise of the seat member 6 is reduced to a minimum, thus reducing the stress required to be exerted in an initial opening of the folding bed members. At the same time the proper forward travel of said seat member 6 is attained in a manner which afi'ords proper clearance between the upholstery finish on gay,

the adjacent parts of the main frame 1 and seat member 6 aforesaid.

11 designates a supporting foot secured to the seat member 6, and adapted to provide a support for the free end of the same, when said seat member is in the unfolded condition illustrated in Figs. 2 and 3. p

12 designates the usual upholstered back of the folding bed, pivoted at its upper end to the transverse connecting rail 3 of the end arms 3 aforesaid,and adapted to be swung up out of the way, in the folding and unfolding operations of the bed parts.

13, 1 1, 15 and 16 designate a series of four bed members or sections pivotally connected one to the other, and adapted when unfolded to constitute a flat bed surface for the mattress and the other accessories of a bed. And when in a folded condition said bed members constitute a rectangular frame which forms within the main frame 1, a containing cavity for the mattress and bed clothing, and to such end the aforesaid bed members or sections will have a detail structural formation as follows:

The rearmost bed section or member 13 is provided with a fixed angularly disposed latch bar 17 at its rear end, and when the bed parts are in an unfolded condition. At said rear end the bed member 13 is pivotally connected to the upper ends of approximately vertical radius links 18, which are in turn pivoted in the lower portion of the main frame 1. In the final opening movements of the bed parts said radius links 18 are adapted to have a forward swing against the stress of springs 19 attached to depending portions of said radius links 18, with a normal tendency toreturn said links to a vertical condition. At the front or end opposite to that above described, the bed member or section 13 is pivotally connected to the next adjacent bed member or section 1 1, and adjacent to such. point of connection, is connected to the main frame 1 by means of supporting links 20, pivotally connected at one end to said bed section 13, and at the other end to the lower and free ends of the swing links 21. The upper ends of the said swing links 21,- ar pivotally connected to the main frame 1, and the arrangement is such that When the bed parts are in a fully opened condition, the links 20 and2l will assume a vertical position and provide a substantial support to the bed members 13 and 14 against a downward sagging in use.

The intermediate bed member or section 14 above referred to is pivotally connected at its forward end to the neXt adjacent intermediate bed member or section 15, and adjacent to such point ofconnection is also .connected to the seat member 6 aforesaid,

by links 22, of an angular form, and which have at their angular portions extensions or knees 23 adapted to restupon ledges 24. in

neceyee the interior of said seat member 6, to support in a substantial manner the bed members 1% and 15 against a downward sagging in use.

The intermediate bed member or section 15 above referred to, is pivotally connected at its outer end to the outer or forward bed member or section 16. This bed member or section 15 controls the height of the receiving or storage cavity for the mattress, etc, when the bed sections are folded together, and accordingly will vary in size to suit different requirements. V

The outer or forward bed member or section 16 above referred to, is provided at its outer end with a folding leg or legs 25 pivoted to said bed section 16, and with a eompanion folding foot board 26 also pivoted to said bed section 15, with the pivots of the parts in spaced relation as shown.

25 designates a tension spring connected at its respectiv ends to the leg 25 and foot board 26 aforesaid, and adapted to move and hold said parts in their fully opened and fully closed positions after the. usual manipulations of said parts by the'operator.

27 designates transverse stay rods extending between side rails of the bed members or sections 14 and 15 and adapted to maintain the same in proper spaced relation in actual use. The stay rods 27 are of the usual hasp or flattened C shape, so that their main portions may lay a distance below the sag point of the usual resilient webs carried by the respective bed sections. In the case of the intermediate bed section 15 aforesaid, its stay rod 27, provides a convenient hand grip for manipulating the bed parts as set forth in the operation of the parts.

28 designates a. movable latch bar pivoted to the rear face of the seat member 6. and adapted to movement in a transverse plane, in one direction under the influence of a spring 29, and in the other direction under the influence of a pull-cord 30. The said movable latch bar 28 is adapted to have engagement beneath the fixed latch bar 17 of the rearmost bed member 13, to latch the series of bed members in their folded condition, as illustrated in Figs. 1 and 2 The operation of the present folding bed structure is as follows Assuming thepai'ts to be in the folded condition shown in Fig. 1, the operator first swings the sofa back 12 into an up position out of the way. After this the pull-cord 30 is manipulated to release the latch mechanism 17, 28, and the seat section or member 6 is then swung position shown in Figs. 2 and 3.

The main part of the above described unfolding movement takes place without any movement of the other bed parts and accord ingly can be effected with a minimum effort on the part of the operator. In its descent, mainly by gravity, into its fully unfolded outward into the inverted condition, the saidseat section 6, through its link connections 22, with the series of bed sections, will draw the said bed. sections, still in their unfolded condition, into theinclined position illustrated in full line in Fig. 2 of the drawings.

The operator by a pulling action on the stay rod 27 of the intermediate bed member 15, moves the series of bed sections, in a still folded condition except as to the rearmost bed section 13, into the horizontal and forward position shown in dotted lines in Fig. 2. After which the bed sections 14, 15 and .16, are serially unfolded into the fully ppenedcondition of the parts, illustrated in ig. 3; i
