7 Claims, 7 Drawing Figures PMENTEDNUVPOIQH 3.772.716 SHEET 2 CF 2 INVENTOR. JOHN W RATCLIFF Attorneys CONVERTIBLE BED BACKGROUND OF THE INVENTION SUMMARY OF THE INVENTION The present invention is directed to an auxilliary bed for a dwelling of limited floor space in which the bed can be moved directly between the storage position to a sleeping position without the necessity of folding or extending components of the bed. As associated with a travel trailer, the bed extends across the width of the trailer, and in the lowered or sleeping position, is supported from the ceiling by a series of flexible cables or chains. One pair of cables is attached to the rear edge of the bed, while a second pair of cables is attached to the ends of the bed, but spaced from the front edge. In the lowered position, the bed is locked to the walls of the trailer by slide bolts or other locking mechanism.
To elevate the bed to the storage position, the front edge of the bed is tilted downwardly, causing the bed to pivot about the connection of the end cables to the bed and thereby elevating the rear edge of the bed above the level of supports which are mounted on the trailer wall adjacent the rear edge of the bed. With the rear edge of the bed tilted to a position above the supports, the front edge of the bed can then be pushed upwardly and moved to the rear so that the rear end of the bed will be supported on the supports. The front edge of the bed is then locked in the storage position by means of slide bolts or other locking mechanism.
The convertible bed of the invention can be stored as a unit without the necessity of folding the bed or contracting components of the bed. This provides a distinct advantage in that it is not necessary to remove the bedding when moving the bed to the storage position, nor is it necessary to fold or remove the mattress.
The bed can be readilymoved between the storage and sleeping position by a single person and as the bed is stored flat against the ceiling it is in an out-of-the-way location where it will not interfere with other activities in the travel trailer or dwelling.
Other objects and advantages will appear in the course of the following description.
The drawings illustrate the best mode presently contemplated of carrying out the invention.
In the drawings:
FIG. 1 is a perspective view of a portion of a travel trailer incorporating the convertible bed of the invention;
FIG. 2 is a top plan view of the bed as shown in the lowered position;
FIG. 3 is a front view of the bed in the lower position with parts broken away in section;
FIG. 4 is a vertical section showing the bed in the lower position;
FIG. 5 is a view similar to FIG. 4 showing the bed in the storage position;
FIG. 6 is an enlarged fragmentary plan view of the forward-most beam and showing the locking mechanism; and
FIG. 7 is an enlarged fragmentary side elevation showing the supporting cable.
FIG. ll shows the convertible bed of the invention as associated with a travel trailer 2. While the drawings illustrate the bed associated with a travel trailer, it is contemplated that the bed may be utilized in any dwelling of limited floor space such as a camper, boat, cabin, aircraft, or the like.
The travel trailer 2 includes a pair of side walls 3 and 4, an end wall 5, and a ceiling 6 which is connected to the upper ends of the side walls and end wall. The bed 1 is mounted so that the long dimension of the bed extends between the side walls 3 and 4 of the trailer and the rear edge of the bed is located adjacent the end wall 5.
The bed' itself includes a series of beams or supports 7, which extends in spaced parallel relation along the length of the bed, and the beams are connected together by a rigid base 8, formed of plywood, wallboard, or the like, which is secured to the upper surface of the beams. As shown in the drawings, the beams are fabricated of tubular steel stock, but it is contemplated that the beams or supports 7 can take various forms. A matress 9, formed of foam plastic, or the like, is supported on the base 8.
Extending upwardly from front beam 7 are a series of tubular vertical supports 10, and a front face board 11 is secured to the vertical supports 10. The face board 11 has a height such that it extends above the level of the mattress 9, and when the bed is in the upper storage position, as shown in FIG. 6, the upper edge of the face board will be adjacent the ceiling so that the matress and any bedding will not be visible. The ends of the beams 7, as well as the ends of the vertical supports 10, are enclosed by plastic caps 12.
In accordance with the invention, the bed I is supported from the ceiling 6 when in the lowered or sleeping position by a pair of rear cables or chains 13 and a pair of front cables or chains 14. As best illustrated in FIG. 2, the rear cables 13 are connected to the projecting ends of the rearmost beams 7 while the front cables 14 are attached to the projecting ends of the second beam 7 from the front of the bed. To provide the attachment of the cables 13 and 14 to the beams, eyelets 15 are secured to the beam ends, and the lower ends of the cables are provided with snap hooks 16 which engage the eyelets. Similarly,.the upper ends of the cables are provided with snap books 17 which are adapted to engage eyelets secured to the ceiling 6. The use of the snap hooks enables the cables and the bed to be removed from the travel trailer if desired.
In the lowered or sleeping position, the bed is supported by the cables 13 and 14 and the bed can be prevented from swinging in a fore and aft direction by engagement of slide bolts 19 with openings 20 formed in the side walls 3 and 4. As best illustrated in FIG. 2, each slide bolt 19 is mounted for sliding movement within a tube 21 mounted between the legs of a U-shaped member 22 secured to the forward beam 7. A stem 23 is secured to each slide bolt and projects outwardly through a slot 24 in the tube 21, and the outer end of stem 23 carries a hand knob 25 to be grasped by the operator.
The slide bolts 19 are of standard construction and can be moved to the engaged position and locked therein by engagement of the stem 23 with a notch 26 that is connected to slot 24.
To elevate the bed to the upper storage position the front edge of the bed is pushed or tilted downwardly, as illustrated in FIG. 4, causing the bed to pivot about the connection of the front cables 14 with the beams and thereby tilting the rear edge of the bed upwardly to a position where the rear beams 7 will be above the level of the supports 27 which are secured to the side walls 3 and 4 adjacent the end wall 5. As shown in FIG. 4, the supports 27 are generally horizontal and have a length such that they will not interfere with upward pivotal movement of the rear edge of the bed. The are inscribed by the rear edge of the bed as it pivots upwardly will clear the forward end of the supports 25.
With the rear beam 7 located above the supports 27, the front edge of the bed is then pivoted upwardly and the bed is pushed rearwardly so that the rear beam 7 will slide rearwardly along supports the 27 toward the end wall 5. With the bed flatwise adjacent the ceiling 6, slide bolts 19 can then be engaged with openings 28 in the side walls 3 and 4 to hold the front edge of the bed in the storage position. As shown in FIG. 6, in this position the cables 13 and 14 are slack.
As shown in FIGS. 3-S, the forward edge of each support 27 is provided with an upstanding lip 29 which prevents the rear beam 7 from sliding off of the supports when the front end of the bed is tilted downwardly.
To lower the bed from the storage position, the slide bolts 19 are released and the front edge of the bed is permitted to drop until the cables 14 are taut. The front edge of the bed can then be depressed, causing the rear edge to pivot upwardly so that the rearmost beam 7 will clear the lips 29 when the bed is pulled forwardly. The rear edge can then be lowered until the bed is in the horizontal sleeping position.
As shown in FIG. 6, when the bed is in the upper storage position, the upper edge of the faceboard 1 l is adjacent the ceiling, so the mattress and other bedding is not visible to occupants of the trailer. Moreover, the exposed beams 7 on the lower surface of the beds, in combination with the base 8, provide a beam ceiling effect which has an attractive appearance.
The convertible bed of the invention stores flat against the ceiling in a position where it will not interfere with normal activities in the trailer or other dwelling. The bed can have a substantial width and as it is stored as a unit, the necessity of folding or retracting any of the components of the bed is eliminated. The bedding can be maintained on the bed while it is in the storage position and this is a substantial advantage in that the removal and replacement of bedding not only requires considerable time, but additional storage space is required for the bedding, and storage space is normally at a premium in a travel trailer or other dwelling of limited floor space.
By use of the tilting principal, the bed can be easily moved between the storage and sleeping positions by a single person. All of the manipulation is applied to the forward edge of the bed and the rear edge of the bed can be located adjacent the end wall where it is not readily accessible.
The term cable as used in the specification and claims is intended to mean any flexible member, such as a chain, rope, straps, or the like. In addition, the terms ends" and side" as applied to the bed are used interchangeably and are not intended to designate the long and short dimensions of the bed.
