SOFA-BED Filed June 20, 1960 2 Sheets-Sheet 1 INVENTOR. Richard I Holt zc law BY M, ha- 41 attorneys 1 Claim. c1. -18) This invention relates to a sofa-bed and has for an ob ject the provision of such a sofa-bed which may be easily moved from a position to support seat cushions in the usual manner to an extended or lateral position whereby the cushions are all supported in the same plane to form a bed.

Another object of my invention is to provide a sofa-bed which shall include a relatively flat, stationary cushion supporting section carried by a supporting frame and a movable cushion supporting section mounted over the stationary cushion supporting section and adapted for movement outwardly and laterally of the stationary cushion supporting section whereby the movable cushion sup porting section is adapted to support a cushion while positioned over the stationary cushion supporting section and both the stationary and movable cushion supporting sections are adapted to support cushions While the movable, cushion supporting section is moved outwardly and laterally of the stationary cushion supporting section.

Another object of my invention is to provide a sofabed of the character designated in which the movable cushion supporting section moves freely relatively to the stationary cushion supporting section and improved means is provided for guiding the movement of the movable cushion supporting section whereby it may be moved to selected positions with a minimum of effort and with a minimum of wear on the moving parts of the sofa-bed. t

A further object of my invention is to provide improved means for limiting outward and lateral movement of the movable cushion supporting section relative to the stationary cushion supporting section whereby the cushion supporting sections are automatically positioned at the correct location for supporting cushions to make a bed.

A still further object of my invention is to provide im- 3,841,635 Patented July 3, 1962 FIG. 5 is a fragmental, sectional view taken generally along the line 5-5 of FIG. 4; and,

FIG. 6 is an enlarged detail view taken generally along the line 6-6 of FIG. 1 and showing the latch means for limiting outward movement of the movable cushion supporting section relative to the stationary cushion supporting section.

Referring now to the drawings for a better understanding of my invention, I show a supporting frame indicated generally at 10 which comprises a'bottom section 11 connected to arm members 12. The supporting frame '10 is mounted on suitable leg members 13, as shown. An elongated member 14 is secured to the forward or outer portion of the supporting frame 10. Extending between the elongated member 14 and the back wall 16 of the supporting frame 10 are suitable brace members 17.

Secured to and supported by the brace members 17 and the elongated member 14 is a stationary cushion supporting section '18, which is preferably formed of a sheet material, such as plywood or the like. Secured to the end edges of the cushion supporting section 18, by any suitable means, such as by screws 19, are channel-shaped guideways 21. As shown in FIG. 3, the channel-shaped guideways 21 are substantially wider than the thickness of the cushion supporting section 18 whereby a recess 22 is provided between the upper flange of the channel-shaped member 21 and the upper surface of the cushion support-' ing section 18:

Mounted above the cushion supporting section 18 is a relatively fiat cushion supporting section 23, which may also be formed of plywood or the like. The end edges of the cushion supporting section 23 extend inwardly of the recesses 22 whereby lateral movement of the cushion supporting section 23 is limited.

As shown in FIG. 5, a plurality of openings 24 are provided in the stationary cushion supporting section 18 for receiving rollers 26 carried by brackets 27. The brackets 27 are secured to the cushion supporting section 18 whereby the rollers 26 engage the under surface of the movable, cushion supporting section 23, thus permitting easy movement of the movable cushion supporting section relative to the stationary cushion supporting section.

proved means for restraining outward movement of the movable cushion supporting section while the device is being used as a sofa.

Heretofore in the art to which my invention relates, various forms of sofa-beds have been proposed. However, so far as I am aware, such beds have been extremely heavy, thus increasing handling and shipping cost, and have required complicated mechanism which not only increases the cost of production of the sofa bed, but provides a hazard in that the fingers of the operator are' easily damaged whenthey are inserted in the moving parts of the sofa-bed as the bed is moved from the sofa position to the extended bed-forming position. To overcome the above and other difiiculties, I provide a relatively light-weight sofa-bed which requires a minimum of moving parts, such as linkages and the like.

A sofa-bed embodying features of my inventon is illustrated in the accompanying drawings, forming a part of this application, in which:

FIG. 1 is a front elevational view showing the sofa-bed in the sofa-forming position;

FIG. 2 is an enlarged sectional view taken generally along the line 22 of FIG. 1 partly broken away and in section;

FIG. 3 is an enlarged, fragmental view taken generally along the line 3-3 of FIG. 2;

FIG. 4 is an end view of the sofa-bed drawn to a slightly larger scale than the sofa-bed shown in FIG. 1 and showing the movable cushion supporting section moved to extended position to form a bed;

Secured to the outer side of the cushion supporting section 23 is an elongated member 28 which extends generally parallel to the elongated support member 14, as shown in FIG. 2. Depending support members, such as channel members 30, support caster rollers 29. The channel members 30 are carried by the lower edges of the elongated member 28, as shown.

Secured to the back side of the elongated member 28 are rearwardly eXtendingrod-like members 31. Suitable openings 32 are provided in the elongated member 14 for slidably receiving the rod-like members 31 whereby the elongated member 28 together with the movable cushion supporting section 23 may be moved outwardly and laterally of the supporting frame 10 and the stationary cushion supporting section 18.

Outward movement of the elongated member 28 and the movable cushion supporting section 23 is limited by suitable stop members, such as bolts 33, which are in threaded engagement with threaded sections 34 provided at the free ends of the rod-like members. That is, upon outward movement of the rod-like members 31, the nuts 33 engage the elongated member 14 and thereby limit outward movement of the rod-like members. By providing a threaded connection between the stop members 33 and the rod-like members 31, the distance that the movable cushion supporting section 23 moves outwardly and laterally of the cushion supporting section 18 may be adjusted. Preferably, the cushion supporting section 23 overlaps the cushion supporting section 18 whenthe movable cushion supporting section 23 is moved to fully exof the fact that the rod-like members .31 extend parallel V to the guideways 211, they also serve as guide members.

Pivotally mounted on the elongated member 14 adjacent the center support 30', by a suitable pin '36, is a latch member 37. A notch 38 is provided in the latch member 37 in position to engage the, support member 39, as shown in FIG. 6. A tension spring 39 connects the arm 37 tothe member 14 whereby the arm 37 is urged toward the support member30a A suitable handle or knob 41 is mounted adjacent the free end of the latch member 37 whereby it may be moved out of engagement with the support member 30 when the movable cushion supporting section 23 is to be moved to extended position. That is, to release the latch 37, it is moved in the direction of the arrow 42 whereby the support member 30 and the movable cushion supporting section '23 arefree to move forward in the direction of the arrow 43.

The cushions for my improved sofa-bed are preferably in the form of separate cushions 44' and .46 which are hingedly connected to eachother as at 47 and are formed of a suitable resilient material such as foam rubber or tion 23 are moved inwardly to the position shown in FIG. 2 whereby the device forms a sofa.

From the foregoing, it will be seen that [have devised an improved sofa bed which is extremely simple of construction, economical of manufacture and one which may be easily manipulated with a minimum of effort and a minimum of instructions. By providing a movable cushion supporting section which has no complicated linkthe like. That is, the outer covering or fabric for the two

cushion sections

44 and 46 are connected to eachother to form a longitudinally extending hinge portion 47 whereby. the cushion section 46 may be folded over the cushion section 44, as shown in FIG. 2, to form a sofa. On the other hand, when the cushions 44 and 4-6 are unfolded, they assume the position shown in FIG. 4. While I have shown the cushions as being hingedly connected to each 1 other, it will be apparent that the cushions may be era-- ployed separately. By employing the cushion section 44 V beneath the cushion section 46 while the device is employed as a sofa, I eliminate entirely the necessity of providing springs for the sofa. That is, the'lower cushion section 44 serves the same function as springs. 7

From the foregoing description, the operation of my improved sofa-bed will be readily understood. To use the sofa-bed as a sofa,- the device assumes the position shown in FIGS. 1 and 2 wherein the movable cushion supporting section 2.3 is above the cushion supporting section 18 and supports both

cushions

44 and 46.

To move .the movable cushion supporting section 23 to extended position to form a bed, the latch 37 is moved in the direction of the arrow 42 whereby the supportmember 30 and the movable cushion supporting section 23 are adapted for outward and lateral movement relative to the supporting frameand the stationary cushion supporting section 18. .As the. movable cushion supportingsection 23 is moved outwardly, the rollers 26 roll relative to the under surface of the cushion supporting section 23 and the end edges of the cushion supporting section 23 move freely Withinthe guideways 21. ,As the movable cushion supporting section Breaches its proper outward position,

' the nuts 33 engage the elongated member 14, thereby limiting any further outwardmovement of the movable cushion supporting section. The cushion .46 is then unfolded whereby it lies on top of the stationary cushion supportting section 18, as shown in FIGS. 4 and 5 to thus form a bed.

To return the movable cushion supporting section 23 to. the sofa position, the cushion 46 is folded over the cushion 44, as shown in FIG. 2, and the elongated member 28 together with the movable cushion supporting secages and the like, I eliminate almost entirely the possibility of the user being injured as the sofa-bed is moved from the sofa position to the extended bed-forming position.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claim. a

What I claim is: v

A sofa-bed comprising a supporting frame, a first flat and continuous cushion supporting section carried by said supporting frame, channel-shaped members mounted at the sides of said first cushion supporting section with the lowermost flanges thereof extending inwardly beneath and secured to said first cushion supporting section and the uppermost flanges thereof extending inwardly 'and spaced above said first cushion supporting section to define guideways bet-ween the upper surface of said first cushion supporting section and said uppermost flanges,
