ORNAN A. HONSINGER, OF TACOMA, WASHINGTON.

FOLDING DAVENPORT-BED.

Application filed May 11, 1915, Serial No. 27,295.

To all whom it may concern I Be it known that I, ORNAN' A. HONSINGER, a citizen of the United States, and resident of Tacoma, in the county of Pierce and State of Washington, have invented certain new and useful Improvements in Folding Davenport-Beds, of which the following is a specification.

My invention relates to davenports which contain folding beds and comprises certain novel structures and combinations thereof which will be hereinafter described and particularly pointed out in the claims.

The object of my invention isto provide an improved structureof the mechanism by which the folding bed is handled, and also to improve the structure of the divanproper.

Further objects of my invention may be ascertained by a study of the following description and claims, said claims also delining the scope of my invention.

in the accompanying drawing 1 have shown my invention in the formof construction, which is now preferred by me. Figure 1 is a plan view of my device with the bed in open position, the central portion being cut away and the b ed-fabric being omitted at one end. 7

Fig. 2 is a transverse sectional elevation through the parts in closed position.

Fig. 3 is a transverse sectional elevation showing the bed opened out.

Fig. 4: is a detail showing the manner of operating the legs by which the outer bed section is supported.

I have herein shown my invention as embodied in a davenport, although it is evident that the folding bed structure shown maybe incorporated with a couch. I do not therefore wish it understood that my invention is in any way limited to a davenport, as it is intended for application to couches as well. I will however, describe it in connection with a davenport as shown.

The main frame 1 as herein shown consists of the main frame structure of the davenport. The folding bed structure is composed of a plurality of sections hinged so as.to fold and stow beneath the seatll when folded. V

The bed frame structure 2, is composed of three sections 20, 21 and 22, the central section 21 being short and extending vertically when the parts are folded. The back or innor section 20 is supported at each end by two or more links 3 and 32, these links be- Specification of Letters Patent.

ing pivoted respectively at 31 and 34; upon the main frame 1 and being pivoted at their other ends, 30 and 33, to the bed frame section 20. In the folded position of the'parts,

links 3 and 32 depend from their fixed pivots and support the inner, or back bed section. 20, close above the floor. In the open or un folded position of the bed, these supporting links extend upwardly from their fixed pivots, as is shown in Fig. 3, and preferably have a slight backward inclination.

A link at, pivoted at 10 to the main frame at each end of the bed, is also pivoted at 41 to the central bed section 21. This link extends beyond the pivot 11 and is connected at 42 to link d3, by which the leg for supporting the outer bed section is controlled. The link 1 has an arm ll projecting later ally, adjacent its fixed pivot 40, this projection being toward the side which is inward when the parts are in folded position and outward when the parts are in open position.

A locking link 46, is pivoted a short distance inward from one end, to the arm 44: by pin 15 and at its other end is provided with .a slot 17, through which passes pin 35,

carried by the bed supporting link 32. This forms a sliding connection with said link, limited in amount by the length of the slot. The other end of this link projects beyond its pivot connection with the link 1 and is pivoted at 1,8 to the outeredge of the seat frame 11. \Vhen the bed is in open position, the under surface of link d6 contacts with thepivot d0 of link 4:, notch 460 in the link 46 engaging pivot .pin 5L0, thereby limiting its movement in one direction. 4 I have provided two springs 37, designed to be under tension when the bed is folded and by their pull to assist the starting of the bed-opening movement. These springs 37, are shown as coiled springs and have one end fixed at 38 upon the main frame. The connection of these springs with the bed frame and their adjustment is such that they exert no pull thereon, excepting during a certain portion of the opening and closing movement while near to the closed position of these parts. This is done by interposing a link' 36, between the spring and the anchorage for its other end. As herein shown, this anchorage consists of the pivot 31 upon which the link 3 swings. The link 3 has a pin 39, projecting into the path of swing of the link 36, whereby when link 36 swings into line with the spring, after which it exerts no more effort upon the bed.

v The rear edge of the seat, or the outer edge 'of'the outer bed section, as the case may be, has pivot-ed thereto, near each end, a leg 5, this leg projecting a short distance above its pivot 50 and having pivot connection with a: link 51, which extends diagonally across the corner of the bed frame and has its other end bent upward and pivotedto the end, of the link 4-3. This link 4L3 is provided with a slot, shown by dotted lines at 5st in Fig. 3, through which extendsa pin 53, carried by the bed section 22.

' hen thebed is open pin 53 contacts with the outer end of this slot and this link then acts to restrain the bar 4 from swinging backward,'or into bed closing position until the outerbed section is raised. It therefore acts as a lock to prevent accidental closing movement. lVhen the bed is swung into closed position, the legs 5 are automatically swung. upward into position substantlally parallel with the bed frame. The seat frame 11 has its rear edge connected with the outer section of the seat frame by a bar 12 at each end thereof. Braces 13 connect bar 12 and the'seat frame;

- The davenport back 6 is supported from the frame 1 by two sets of links, 7 and 72, the former engaging the lower part of the back and the latter the upper part. The pivot connections of the linkswith the frame are farther separated than their connection with the back. In consequence of thisandof the choice of location of the pivot points, together with the length of the links,one or the other set of the links will hold the back in either of its extreme positions. In effect they form a double toggle joint, resisting a downward force when in the open position, and an upward force when in the closed position.

The upper ends of the upper links 72 are "pivoted at 73 to the frame and their lower ends to'the back. Stops 74E prevent their swing back beyond the position shown. In the normal or closed position of the davenport,the links 72 are" substantially in line 'with the back, being slightly inclined-from the vertical. The lower edge of the back projects over the rear edge of the seat, and therefore prevents raising of. the seat until the back is swung out of the way.

The top of the back may swing freely forward from the closed position. hen it is swung forward the back is raised somewhat.

,This action swings the lower links .backward until they come into a vertical position, or just past this; that is, they come into substantialalinement with the back. The back may be held in this position by frictional engagement with the links 7 at 71 V or by any other suitable means. These links act to hold the back in this position until the bottom edge is pulled forward. The back is thus held rearwardly of and above its normal position by the second toggle joint while the bed is open. 7

j The back is carried by the lower links at a point well forward of its center of gravity. The' resulting effect is for the upper end of the back to swing backward. The movable pivot of the link 72is back of a line from the fixed pivot 73 through the frontlower edge of the back, the point where an upward force would be applied, when the back is in closed position. The back will not swing forward under'the influence of an upward force'along the line described or'along any line forward of this line, and stops 74'limit its backward swing. It is therefore securely locked, as by a toggle joint, against moving by an upward force applied at its lower edge. The toggle may be broken, and the back swung upward only by a forward pull on the upper edge of the back. I r

The central sections 21 of'the bed frame are connected by'astrut 8, which'consists of a tube offset at each endso as to drop its central portion beneath the bed fabric, and having a pivotal connection with the section 21. The purpose of this strut is to hold the centralportion of the ends of the bed frame apart.

\Vith the parts in folded position, as shown in Fig. 2, to open the bed the upper part of the back is pulled forward. swings the back upon the links 72 and the This upward pull given'by these links causesthe the rear edge of the seat. "The rear edge of the seat may then be raised and swung forward. This causes the folded bed frame to swing upon the bars 4:, the outer or front section 22, swinging with the seat and the inner section 20 swinging backward and then upward, until the parts reach the position shown in Fig. 3.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent of the United States of America. 1s:
