FOLDING BED.

Application filed. November 3, 1923.

To all to/1.0m it may concern:

Be it known that I, JOHN P. HARTMAN, a citizen of the United States, residing at San Francisco, in the county of San Franeisco and State of California, have invented new and useful Improvements in Folding Beds, of which the following is a specification.

This invention relates to folding beds.

The principal object of this invention is to produce a folding bed which when folded is of standard size and capable of receiving a standard size mattress.

Another object is to produce a folding bed which will be, when folded, sightly in appearance and entirely concealing the fact that the same is a bed.

A still further object is to produce a bed which will be easily manipulated, thus relieving the operator of the customary strain incident to opening many of the heavy folding beds now upon the market.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which. like numerals are employed to designate like parts throughout the same,

Figure 1 is a top plan view of with the springs removed for the of clearness,

Figure 2 is a side elevation of Figure 1,

Figure 3 is a side elevation of my folding bed in closed position, and

Figure fl: is a top plan view of Figure 3.

There are many folding beds now upon the market which are cumbersome to operate, expensive to manufacture and unsightly when folded. Applicant has therefore produced a folding bed which obviates all of these disadvantage-s.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a back-frame which has extending forwardly, parallel braces 6 and 7, it being understood that similar braces are positioned at both ends of the back-frame. These braces are connected at their forward end by an upright as shown at 8. These uprights are, in turn, joined by a longitudinal spacer 9. At 4 I have shown av section of the arm.

A similar longitudinal spacer 11 is mounted in the back frame 5. Parallel members my bed purpose Serial No. 672,654.

12 and 13 serve to connect the longitudinal spacer .9 and the back frame The spring-retaining frame is preferably formed of angle iron having a U-shaped head section 1 1 pivoted as at 16 and 17 by means of supporting brackets 18 and 19, which are mounted upon the longitudinal spacer 1L Intermediate frame sections are connected to the ends of the U-shaped head section and are designated by the numerals 21 and 22, and are pivoted as at 23 and 2 1 (see Fig. 1). A U-shaped foot section 26 is pivoted as at 27 and 28 to the free ends of the intermediate sections 21 and 22.

In order to support this frame in prop er alignment, a radius link 29 is pivoted to each of the intermediate sections at 30 and to each of the parallel members 12 and 13,respectively as at 35.

An off-set brace 31 is also secured to the intermediate members at a point between the brace 29, in order to further strengthen the frame-work.

At 32,51 have shown a seat cushion sup porting frame which is pivoted as at 38 anc to the longitudinal member 9. This frame has its free edge secured to the U- shaped foot portion of the spring frame as by links 36. These links are adapted to ride upon a pin 37 through the medium of a slot 38 so as to accommodate for the folding operation. A similarly constructed link 39 supports one end of the back-supporting cushion, frame 4-1. The opposite end of this frame is connected by a link 12 to the front end of the foot section as best shown in Figure 2. A cover board 10 is attached to the frame 411 the use of which is obvious by viewing Figures 2 and 3.

A foot-board 43 is pivoted to the footsection by curved supports 441'. Supporting legs pivoted at 50 are positioned upon each side of the foot section and are designated by the numerals 4:6. from the foot section by brackets 4-,? so as to avoid the elements 39 and 41, and are connected by a cross piece or operating handle 18. It is of course understood that the customary upholstery is placed upon the entire outer surface of the frame of the bed so as to present a neat appearance. This upholstery is shown in dotted lines in Fig ure 3;

At 49 and 51, 52 and 53, I have shown springs for assisting in the opening and closing operation. These springs bei proper- These legs are offset 1y tensioned so as to balance the load during the major part of the opening and closing movement and also cause the joint between the head and intermediate sections tobreak downwardly.

Assuming that the parts are in closed position, as shown in Figure 8, the operator grasps the back at a point near the coverboard 40 and pulls the same toward the front of the divan. It is assumed, in this instance, that the seat cushion is attached to the frame 32, this, however, may be removable, if so desired. The forward movement of the back causes the frame-work to pivot upon its respective joints sothat continued forward movement will result in the frame sec tions extending into the position shown in Figures 1 and 2. The weight of the forward section and intermediate section together with their respective cushions is sufficient to prevent any collapse of the bed should a heavy-weight be placed near the joint 24 of the sections.

Due to the fact that the springs are connected to the head section, intermediate section and foot section, which results in the weight being evenly distributed to all sections thereby preventing any possibility of collapse due to a localized weight.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be restortcd to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, 1 claim In a device of the character described, a

back frame, braces extending from said back frame, uprights secured to said braces, longitudinal spacers extending between said braces, a longitudinal member secured to said back-frame, parallel members extending between said longitudinal spacers, a U shaped angle iron head section, pivoted to said longitudinal member, intermediate angle iron members pivoted to said head section, a radius link extending between said intermediate members and said parallel members, an otfset braceextending between said intermediate members, a foot section pivoted to said intermediate members, a seatframe pivoted to the foremost of said longitudinal spacers, and supported from said foot section by sliding links, legs offset from said foot section, and pivoted thereto, and a back cushion frame secured to said foot section.

In testimony whereof I atfix my signature.

JOHN P. HARTMA-N.
