Definitions
- the present invention relates to convertible furniture. More specifically, it relates to sofas that convert between sitting and sleeping configurations.
- Sofas are commonly sold as sitting furniture that allows more people to comfortably sit side-by-side as compared to other furniture, such as an individual chair. Sofas range in size from small two-person love seats to large couches that can hold four or more people. Some sofas include mechanisms that allow the seat portion to unfold outward and forward to convert into a bed. This combination is commonly called a “sleeper sofa”, “stowaway sofa”, or “sofa bed”.
- Sofa beds provide the convenience of a dual-purpose piece of furniture, and there are several kinds, each with their own sets of components assembled to realize a mechanism that switches the sofa bed between the sofa and bed configurations.
- These component assemblies mean that sofa beds may have complicated internal construction assemblies. These assemblies may be made up of metal tubes, attachments, and other metal members.
- a shortcoming of existing sofa beds it that the internal assemblies result in high manufacturing costs. Another shortcoming is that the internal assemblies may weigh so much that the sofa bed is difficult to move around or lift for the average person. Another shortcoming is that the internal assemblies may include so many components that they are subject to easy damage or breakage. Further, the internal assemblies may be difficult and costly to repair.

- FIGS. 4 and 5 shows sofa bed 100 without any cushions 21 , 22 , 23 or armrests 1 .
- the sofa bed 100 comprises first, second, and third seat bases 31 , 32 , 33 , stand bars 30 , reinforcing rod 34 , support leg 40 , first and second connectors 51 , 52 , ratchet bracket 61 , clip 420 , backing support 422 , vertical supports 424 , lateral supports 426 , armrest bracket 428 (which is attached to the armrest 1 ), box frame 430 , and cross supports 432 .
- the vertical supports 424 are complementary to the stand bars 30 and preferably extend from the first seat base 31 to lateral support 426 as shown in FIG. 4 .
- the clip 420 is preferably attached to the backing support 422 and/or the vertical supports 424 using a suitable fastener.
- the clip 420 will deflect and lock on to strut or crossbar 57 which helps to keep the sofa bed 100 in the sofa configuration. This is particularly useful for installations of sofa bed 100 in moving vehicles, such as recreational vehicles, to keep the sofa bed 100 from opening while the vehicle is in motion due to vibration and comparable forces.
- Alternative fastening mechanisms may be used to maintain the sofa bed 100 in the sofa configuration.
- the locking system 500 may be spring loaded and thus biased toward the bed configuration.
- the crossbar 57 is preferably stationary.
- FIGS. 7-9 the structure and function of the locking system 500 is depicted including first hinge joint 434 connected to first seat base 31 and second hinge joint 436 connected to second seat base 32 .
- FIG. 8 shows the sofa bed 100 in the sofa configuration. In this configuration, slider stop 64 is positioned toward first end 65 . When the sofa bed 100 is moved from the bed configuration to the sofa configuration, the slider stop will move along ratchet bracket 61 and teeth 62 toward second end 66 , as shown in FIG. 9 .
- first and second connectors 51 , 52 preferably rotate/slide past and do not interfere with each other as the sofa bed 100 opens and closes.
- first and second connectors 51 , 52 are preferably offset.
- FIG. 10 shows alternative sofa bed 700 , which is substantially the same as sofa bed 100 .
- the difference depicted in FIG. 10 is notch or gap 710 , wherein the armrest 1 structure does not extend to the floor, as shown in FIG. 1 .
- Notch 710 allows sofa bed 700 to be installed on a raised and/or movable surface, such as a slide-out floor in a recreational vehicle.
- the notch 710 may vary in height, preferably from 1 to 12 inches for most applications, and, consequently, the lower-most height of the mechanism of sofa bed 100 , 700 is complementary to the height of the notch 710 .
- Traditional sofa beds cannot comprise a notch 710 because the mechanism of such beds occupies the space of notch 710 because such prior art mechanisms are installed near the bottom of the sofa (i.e., substantially adjacent to the floor). In that way, the overall distance from the floor to the seat or bed of sofa bed 700 is reduced, as compared to a sofa bed lacking the notch 710 . This improves the safety and accessibility of sofa bed 700 , particularly in RV applications.
- the overall height of sofa bed 700 in RV installations may be adjusted, i.e., using different notch 710 sizes, spacers, or slide-out floor heights and/or elevations to accommodate a desired sofa bed 700 of a user.
- FIG. 11 shows sofa bed 100 or 700 , wherein third seat cushion 23 , 730 preferably extends to a position that is substantially flush with the back 740 of armrest 1 , namely, the portion depicted in position against or adjacent to wall 720 in FIG. 11 .
- this feature is particularly advantageous in RV applications where space is limited.
- sofa bed 100 , 700 may be installed against a wall 720 of an RV, wherein it is desirable for there to be no space wasted between the back 740 and the wall 720 when the sofa bed 100 , 700 is in the bed configuration as shown.
- Such installations are also applicable in small spaces other than RVs.
- the seat base 31 may be lifted vertically by way of an optional handle 50 or similar device preferably connected to base 31 or backing support 422 .
- FIG. 1 shows sofa bed 100 and base 31 in a slightly lifted position in preparation for extension into the bed configuration.
- the clip 420 is released from crossbar 57 and the sofa bed 100 may extend from the sofa configuration shown in FIG. 1 to the bed configuration shown in FIG. 2 .
- the slider stop 64 will move along ratchet bracket 61 from the second end 66 toward the first end 65 .
- first glide wheel 211 in first slide 41 second glide wheel 401 in second slide 42 and preferably first and second casters 300 , 400 enable the sofa bed 100 to smoothly glide outwardly from a sofa configuration to a bed configuration as a user pulls gently on the handle 50 .
- locking rod 63 will generally coax the movement of second seat base 32 by way of the connection of end 67 to second hinge joint 436 .
- the seat base 31 is preferably once again lifted vertically by way of an optional handle 50 . This will engage the slider stop 64 with the teeth 62 . As best shown in FIG. 9 , movement toward the sofa configuration will cause the slider stop 64 to move toward end 66 , as locking rod 63 pushes upwardly on second hinge joint 436 connected to protrusion 332 of second seat base 32 . As shown, this pushes second seat base 32 and third seat base 33 into a substantially A-frame intermediate configuration, wherein the third seat cushion 23 is substantially tucked away in the armrest 1 , and second seat cushion 22 once again becomes a substantially vertical support surface for sitting, and first seat cushion 21 becomes a substantially horizontal surface for sitting.
- the clip 420 will connect with crossbar 57 and hold the sofa bed 100 in the sofa configuration until bed deployment is once again desired.
- sofa bed 100 , 700 provides numerous advantageous and unique features over the prior art.
- a standard sofa bed has its mechanism placed beneath the seats of the sofa, and the seat cushions must be removed to open the metal mechanism.
- the mechanism of sofa bed 100 , 700 is preferably not placed beneath the seat base 31 ; it actually includes the seat bases 31 , 32 , 33 and corresponding cushions 21 , 22 , 23 as part of the bed.
- the cushions 21 , 22 , 23 do not need to be removed and stored while the sofa bed 100 , 700 is in use in any configuration.
- the sofa bed 100 , 700 has first and second sets of casters or wheels 300 , 400 that allow the sofa bed 100 , 700 to be moved in a single continuous motion when it is open or closed.
- the back of sofa bed 100 , 700 is preferably a double-sided cushion 22 , 23 mechanism that allows it to fold flat to become part of the bed surface, as shown in FIGS. 1, 2 . It is easy for anyone to use and does not require the cushions 21 , 22 , 23 to be removed.
- a traditional trifold sleeper has a large fold down back “flap” that becomes a part of the mattress, but is harder to reach and fold back up, and it is one more step to operate as compared to the advantageous sofa bed 100 , 700 .
- a traditional sofa bed mechanism is attached to the inside of the arms which takes up about 8-10 inches of width on each side, thus reducing the sleeping space of the mattress or making the entire sofa width wider.
- the sofa bed 100 , 700 mechanism is attached very closely to the inside 750 of armrests 1 allowing for little clearance and a wider sleeping and sitting surface 760 on a sofa bed 100 , 700 that may have a greater ratio of surface 760 width to overall sofa bed 100 , 700 width, as compared to such ratios of traditional sofa beds.
- the sofa bed 100 , 700 comprises the seat bases 31 , 32 , 33 that all extend and revert together as a single unit to form the sleep surface 760 .
- the back height 770 and sleep surface 760 of sofa bed 100 , 700 can be adjusted in production or by a user to fit tight areas.
- a standard sofa bed mechanism also requires about 12 inches of clearance from the sofa back to move upward for the mattress storage, whereas as the sofa bed 100 , 700 mechanism can be very close to the wall 720 at all times, thus allowing for a longer mattress that is closer to the wall 720 and consequently conserves space as compared to traditional mattresses that extend further into the space where the sofa bed is installed.
- This feature of sofa bed 100 , 700 is particularly advantageous in tight spaces such as RVs.
- the sofa bed 100 , 700 has a built in “lock” position that keeps the unit from opening when it is in the seat configuration, the lock position being facilitated by the interaction of the clip 420 and strut 57 .
- handle 50 may be grasped and the seat base 31 lifted upwardly a few inches such that the clip 420 and locking mechanism 500 will release.

Abstract
Description
- This application claims the priority benefit of Chinese Utility Model Patent Application No. CN201922193208.0U filed on Dec. 9, 2019, now Chinese Utility Model Patent Grant No. CN211632507U.
- The present invention relates to convertible furniture. More specifically, it relates to sofas that convert between sitting and sleeping configurations.
- Sofas are commonly sold as sitting furniture that allows more people to comfortably sit side-by-side as compared to other furniture, such as an individual chair. Sofas range in size from small two-person love seats to large couches that can hold four or more people. Some sofas include mechanisms that allow the seat portion to unfold outward and forward to convert into a bed. This combination is commonly called a “sleeper sofa”, “stowaway sofa”, or “sofa bed”.
- Sofa beds provide the convenience of a dual-purpose piece of furniture, and there are several kinds, each with their own sets of components assembled to realize a mechanism that switches the sofa bed between the sofa and bed configurations. These component assemblies mean that sofa beds may have complicated internal construction assemblies. These assemblies may be made up of metal tubes, attachments, and other metal members.
- A shortcoming of existing sofa beds it that the internal assemblies result in high manufacturing costs. Another shortcoming is that the internal assemblies may weigh so much that the sofa bed is difficult to move around or lift for the average person. Another shortcoming is that the internal assemblies may include so many components that they are subject to easy damage or breakage. Further, the internal assemblies may be difficult and costly to repair.
- What is needed is a sofa bed that has a simplified internal assembly that reliably transitions the sofa bed between the bed and sofa configurations. What is also needed is an internal assembly that is lightweight so that the sofa can be easily moved. What is also needed is an internal assembly that is conducive to repair and resistant to damage.
- The present invention is an apparatus for use as a convertible sleeping and sitting surface. Specifically, the apparatus is a sofa bed with an enhanced glide apparatus for transitioning between the sofa and bed configurations.
- One embodiment of the present disclosure is sofa bed that includes a pair of armrests; at least one first seat cushion disposed between the pair of armrests; at least one first connector attached to each of the at least one first seat cushion; at least one second seat cushion disposed between the pair of armrests; at least one second connector attached to each of the at least one second seat cushion, wherein the at least one first connector and the at least one second connector form a hinge joint; at least one third seat cushion disposed between the set of armrests; a first seat base attached to the at least one first seat cushion; a pair of stand bars supporting the first seat base; a second seat base attached to the at least one second seat cushion; a third seat base attached to the at least one third seat cushion, wherein the second seat base and the third seat base are connected in a hinge joint; a pair of rotating shafts, each disposed in one of the armrests, wherein the third seat base is attached to the rotating shafts opposite the hinge joint with the second seat base; a pair of support legs configured to support the second seat base; a pair of first slide rails, each attached to one of the pair of support legs; a pair of first glide wheels, each connected to at least one of the first connectors, wherein each of the first slide rails is configured to receive the first glide wheel and allow it to roll along at least part of the length of the first slide; a pair of second slide rails, each attached to one of the pair of armrests; and a pair of second glide wheels, each of the second glide wheels connected to one of the support legs, wherein each of the second slides is configured to receive the second glide wheel and allow it to roll along at least part of the length of the second slide. The sofa bed may also include a locking mechanism. Where the first seat base has a side distal to the second seat base and a side proximal to the second seat base and the second seat base includes a protrusion opposite the second seat cushion, the locking mechanism may include a pair of reinforcing rods, each with a first side and a second side, wherein the each of the first sides is attached to the corresponding distal side of the first seat base and each of the second sides is attached to the corresponding proximal side of the first seat base; a pair of ratchet brackets, each comprising an L-shaped bar with a long side and short side and comprising indentations along the long side, the short side being attached to the reinforcing rod and the long side being attached to the proximal side of the first seat base; a pair of locking rods, each with one end attached to the corresponding protrusion on the second seat base and the other end engaging the teeth of the ratchet bracket; and a pair of slider stops, each surrounding a long side of one of the ratchet brackets and comprising a spring between the slider stop and the locking rod to apply force to maintain engagement between the teeth and the locking rod. The sofa bed may also include a support pad disposed on each of the first slides to support the second seat base and the third seat base. The sofa bed may also include a pair of first casters, each on one of the stand bars; and a pair of second casters, each on one of the support legs. The third seat base may include a pair of connection plates and each of the rotating shafts may connect to the third seat base at one of the connection plates.

FIGS. 1-3 show diagrams of thesofa bed 100 according to one embodiment of the present disclosure.FIG. 1 shows a side view of thesofa bed 100 includesarmrests 1, afirst seat cushion 21, asecond seat cushion 22, athird seat cushion 23, afirst seat base 31, asecond seat base 32 and athird seat base 33. Thearmrest 1 is constructed with an internal metal frame that may be wrapped with foam and polyurethane leather or other suitable upholstery material. Thearmrests 1 are disposed on the left and right sides of thesofa bed 100. - The parts of this disclosure may be discussed in singular or paired fashion, as one side of the
sofa bed 100 would be understood by a person of skill in the art to have symmetry between the parts on each side but may have singular or paired parts between pairs of other parts. For example, a person of skill in the art would understand that a sofa has two armrests. Also, a person of skill in the art would understand that a sofa may be designed to have a pair of cushions or a single long cushion. - The
first seat cushion 21, thesecond seat cushion 22, and thethird seat cushion 23 are disposed between the pair ofarmrests 1. The seat cushions 21, 22, 23 may be constructed of a plywood ormetal base first seat base 31, thesecond seat base 32, and thethird seat base 33 correspond to one of theseat cushions seat base corresponding seat cushion seat cushions sofa bed 100. - A
first connector 51 is attached to thefirst seat cushion 21 and asecond connector 52 is attached to thesecond seat cushion 22. Thefirst connector 51 and thesecond connector 52 are attached to each other by a fastener that acts as ahinge 335 and allows the twoconnectors first seat cushion 21 and thesecond seat cushion 22 can move relative to one another to jointly form a substantially planar surface in the bed configuration and at least one of: an acute, right, or obtuse angle in sofa configuration as would be understood by a person of skill in the art.Connectors - The
first seat base 31 may be made of metal. A reinforcingrod 34 may be attached to thefirst seat base 31. The reinforcingrod 34 may be bent or curved rather than straight. Each of the ends of the reinforcingrod 34 may be connected proximate to or at the ends of thefirst seat base 31. The reinforcingrod 34 may be made of metal as well. - The
first seat base 31 may be supported by two stand bars 30. Each of the stand bars may be connected on one end to thefirst seat base 31 and have afirst caster 300 attached on the other end for contact with a floor surface, such that thefirst seat base 31 will roll on the floor when moved toward or away from the rest of thesofa bed 100. The first seat base, viewed from the side, may be L-shaped. The short side of the L-shaped may be used as an attachment point for part of the ratchet or lockingsystem 500 discussed further below. - As with the
first seat base 31, thesecond seat base 32 and thethird seat base 33 may also be made of metal or another suitable material that provide structural support and attachment points for the other components. Ahinge 336 may connect the side of thesecond seat base 32 distal from thefirst seat base 31 with one side of thethird seat base 33. -
FIG. 3 shows an exploded side view of thesofa bed 100. Thethird seat base 33 may include a hump orconnection plate 331 on its underside and distal from thesecond seat base 32 andhinge 336. Thearmrest 1 may haverotating shaft 11 or axle attached to it. Theconnection plate 331 includes an opening through which part of therotating shaft 11 may be inserted, such that thethird seat base 33 can rotate about the rotatingshaft 11 and change its orientation relative to thearmrest 1. As seen inFIG. 2 , which is a side view of thesofa bed 100 in the bed configuration, the rotation of the seat bases 31, 32, 33 relative to one another on their respective hinges allows thesofa bed 100 to move from the sofa configuration to the bed configuration. Thesecond seat cushion 22 and thethird seat cushion 23 that were facing in opposite directions relative to theirseat bases FIG. 1 are now facing in the same direction inFIG. 2 . The rotatingshaft 11 allows thethird seat cushion 23 to move relative to thearmrest 1 by rotating but remain fixed at the point of therotating shaft 11. - When shown in the sofa configuration, it can be seen that the
sofa bed 100 includes a system for sliding and locking the seat bases 31, 32, 33 so that thesofa bed 10 can be transitioned between the sofa configuration and the bed configuration. - A
support leg 40 may be attached to afirst slide 41 and asecond slide 42. The support leg may be metal and L-shaped. A vertical portion of thesupport leg 40 may have asecond caster 400 disposed on its end between thesupport leg 40 and the floor surface. Thefirst slide 41 is a slide rail attached to the top of the horizontal portion of thesupport leg 40. Afirst glide wheel 211 may be attached to thefirst connector 51 in a position where thefirst glide wheel 211 is received by thefirst slide 41 and can roll along with thefirst slide 41. Asupport pad 410 may be disposed on top of thefirst slide 41 to support thesecond seat base 32 and thethird seat base 33 when thesofa bed 100 is in the bed configuration. Thesecond slide 42 is a slide rail attached to thearmrest 1. The horizontal portion of thesupport leg 40 may have asecond glide wheel 401 disposed along its length that can roll along the length of thesecond slide 42. In some embodiments, thesecond glide wheel 401 may be attached to thefirst slide 41. - The
locking system 500 may include aratchet bracket 61 withteeth 62, a lockingrod 63, aslider stop 64, and first and second hinge joints 434, 436. Theratchet bracket 61 may be metal and L-shaped, with theteeth 62 disposed along the long part of the L. The teeth are made up of indentations in theratchet bracket 61 and define positions along the length of the long side. One end of theratchet bracket 61 is connected to the reinforcingrod 34, and the other end is connected to thefirst seat base 31. Alternative fastening mechanisms may be used. - The
second seat base 32 includes aprotrusion 332 on its underside proximal to thefirst seat base 31. Similarly, thefirst seat base 31 may include a protrusion or bracket to which first hinge joint 434 is connected at the underside ofbase 31. Theprotrusion 332 includes an opening for forming ahinge joint 436. The lockingrod 63 is a bent metal bar with one end connected to theprotrusion 332 at thehinge joint 436. The other end of the lockingrod 63 is positioned to engage at least one of theteeth 62. Theslider stop 64 is metal and surrounds part of the long side of theratchet bracket 61. Theslider stop 64 is configured to slide along one side of theratchet bracket 61 and assist in the engagement of the lockingrod 63 with theteeth 62. Aspring 641 is attached between theslider stop 64 and the end of the lockingrod 63 proximal to theslider stop 64. The force from thespring 641 holds the lockingrod 63 engaged with at least one of theteeth 62 unless acted on by another force. -
FIGS. 4 and 5 showssofa bed 100 without anycushions armrests 1. As shown, thesofa bed 100 comprises first, second, and third seat bases 31, 32, 33, stand bars 30, reinforcingrod 34,support leg 40, first andsecond connectors ratchet bracket 61,clip 420, backingsupport 422,vertical supports 424, lateral supports 426, armrest bracket 428 (which is attached to the armrest 1),box frame 430, and cross supports 432. - As shown in
FIG. 6 , thevertical supports 424 are complementary to the stand bars 30 and preferably extend from thefirst seat base 31 tolateral support 426 as shown inFIG. 4 . Theclip 420 is preferably attached to thebacking support 422 and/or thevertical supports 424 using a suitable fastener. When thesofa bed 100 is in the sofa configuration, theclip 420 will deflect and lock on to strut orcrossbar 57 which helps to keep thesofa bed 100 in the sofa configuration. This is particularly useful for installations ofsofa bed 100 in moving vehicles, such as recreational vehicles, to keep thesofa bed 100 from opening while the vehicle is in motion due to vibration and comparable forces. Alternative fastening mechanisms may be used to maintain thesofa bed 100 in the sofa configuration. Thelocking system 500 may be spring loaded and thus biased toward the bed configuration. Thecrossbar 57 is preferably stationary. - As shown in
FIGS. 7-9 , the structure and function of thelocking system 500 is depicted including first hinge joint 434 connected tofirst seat base 31 and second hinge joint 436 connected tosecond seat base 32.FIG. 8 shows thesofa bed 100 in the sofa configuration. In this configuration,slider stop 64 is positioned towardfirst end 65. When thesofa bed 100 is moved from the bed configuration to the sofa configuration, the slider stop will move alongratchet bracket 61 andteeth 62 towardsecond end 66, as shown inFIG. 9 . Additionally, asratchet bracket 61 preferably moves in tandem with first andsecond connectors sofa bed 100 is moved from bed to sofa configurations, and vice versa, thebracket 61 will move in tandem with first andsecond connectors second connectors sofa bed 100 opens and closes. As best shown inFIG. 5 , first andsecond connectors -
FIG. 10 showsalternative sofa bed 700, which is substantially the same assofa bed 100. The difference depicted inFIG. 10 is notch orgap 710, wherein thearmrest 1 structure does not extend to the floor, as shown inFIG. 1 .Notch 710 allowssofa bed 700 to be installed on a raised and/or movable surface, such as a slide-out floor in a recreational vehicle. Thenotch 710 may vary in height, preferably from 1 to 12 inches for most applications, and, consequently, the lower-most height of the mechanism ofsofa bed notch 710. Traditional sofa beds cannot comprise anotch 710 because the mechanism of such beds occupies the space ofnotch 710 because such prior art mechanisms are installed near the bottom of the sofa (i.e., substantially adjacent to the floor). In that way, the overall distance from the floor to the seat or bed ofsofa bed 700 is reduced, as compared to a sofa bed lacking thenotch 710. This improves the safety and accessibility ofsofa bed 700, particularly in RV applications. The overall height ofsofa bed 700 in RV installations may be adjusted, i.e., usingdifferent notch 710 sizes, spacers, or slide-out floor heights and/or elevations to accommodate a desiredsofa bed 700 of a user. -
FIG. 11 showssofa bed third seat cushion armrest 1, namely, the portion depicted in position against or adjacent to wall 720 inFIG. 11 . Like thenotch 710, this feature is particularly advantageous in RV applications where space is limited. For example,sofa bed wall 720 of an RV, wherein it is desirable for there to be no space wasted between the back 740 and thewall 720 when thesofa bed - In operation from the sofa configuration to the bed configuration, the
seat base 31 may be lifted vertically by way of anoptional handle 50 or similar device preferably connected to base 31 orbacking support 422.FIG. 1 showssofa bed 100 andbase 31 in a slightly lifted position in preparation for extension into the bed configuration. By liftingbase 31, theclip 420 is released fromcrossbar 57 and thesofa bed 100 may extend from the sofa configuration shown inFIG. 1 to the bed configuration shown inFIG. 2 . During deployment of thesofa bed 100 into the bed configuration, theslider stop 64 will move alongratchet bracket 61 from thesecond end 66 toward thefirst end 65. Moreover, the combination ofrotating shaft 11,hinge 336,connectors hinge 335,first glide wheel 211 infirst slide 41,second glide wheel 401 insecond slide 42 and preferably first andsecond casters sofa bed 100 to smoothly glide outwardly from a sofa configuration to a bed configuration as a user pulls gently on thehandle 50. Additionally, lockingrod 63 will generally coax the movement ofsecond seat base 32 by way of the connection ofend 67 tosecond hinge joint 436. Once thesofa bed 100 is fully deployed in the bed configuration, theslider stop 64 will be preferably disengaged fromteeth 62. - To move the
sofa bed 100 back into the sofa configuration, theseat base 31 is preferably once again lifted vertically by way of anoptional handle 50. This will engage the slider stop 64 with theteeth 62. As best shown inFIG. 9 , movement toward the sofa configuration will cause theslider stop 64 to move towardend 66, as lockingrod 63 pushes upwardly on second hinge joint 436 connected toprotrusion 332 ofsecond seat base 32. As shown, this pushessecond seat base 32 andthird seat base 33 into a substantially A-frame intermediate configuration, wherein thethird seat cushion 23 is substantially tucked away in thearmrest 1, andsecond seat cushion 22 once again becomes a substantially vertical support surface for sitting, andfirst seat cushion 21 becomes a substantially horizontal surface for sitting. When thesofa bed 100 is fully returned to the sofa configuration, theclip 420 will connect withcrossbar 57 and hold thesofa bed 100 in the sofa configuration until bed deployment is once again desired. - As shown in the figures and described above,
sofa bed sofa bed seat base 31; it actually includes the seat bases 31, 32, 33 andcorresponding cushions cushions sofa bed sofa bed wheels sofa bed sofa bed sided cushion FIGS. 1, 2 . It is easy for anyone to use and does not require thecushions advantageous sofa bed sofa bed armrests 1 allowing for little clearance and a wider sleeping and sittingsurface 760 on asofa bed surface 760 width tooverall sofa bed - The
sofa bed sleep surface 760. Theback height 770 andsleep surface 760 ofsofa bed sofa bed wall 720 at all times, thus allowing for a longer mattress that is closer to thewall 720 and consequently conserves space as compared to traditional mattresses that extend further into the space where the sofa bed is installed. This feature ofsofa bed sofa bed clip 420 andstrut 57. To open thesofa bed seat base 31 lifted upwardly a few inches such that theclip 420 andlocking mechanism 500 will release. Thehandle 50 may be lowered and gently pulled outwardly, such that thecasters sofa bed sofa bed sofa bed handle 50 may be grasped again and the base 31 lifted upwardly between preferably 1 to 10 inches from the floor to engage thelocking mechanism 500. In normal operation, an audible “click” may be heard, indicating that thelocking mechanism 500 is engaged. This will cause the adjacent edges ofbases rod 63 pushes onbase 32 toward an A-frame shape as described above and shown inFIG. 9 . Thehandle 50 may then be used to push thesofa bed base 31 becomes the seat and thebase 32 becomes the backrest once more. When thesofa bed clip 420 will once again engage thestrut 57 and remain biased in the sofa configuration. - While embodiments in the present disclosure have been described in some detail, according to the preferred embodiments illustrated above, it is not meant to be limiting to modifications such as would be obvious to those skilled in the art.
- The foregoing disclosure and description of the disclosure are illustrative and explanatory thereof, and various changes in the details of the illustrated apparatus and system, and the construction and the method of operation may be made without departing from the spirit of the disclosure.
