The disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. As used in the specification and the appended claims, the singular forms a, an, the, and the like include plural referents unless the context clearly dictates otherwise. In addition, while reference may be made herein to quantitative measures, values, geometric relationships or the like, unless otherwise stated, any one or more if not all of these may be absolute or approximate to account for acceptable variations that may occur, such as those due to manufacturing or engineering tolerances or the like.

(17) As used herein, the term convertible furniture refers to a seat having a first or seat configuration and a second or bed configuration. Convertible furniture as used herein may refer to a single seat or multi-seat unit. For example, convertible furniture may have a single seat, two seats, three seats, or more than three seats. Each seat of the convertible furniture may be independently articulatable between the seat configuration and the bed configuration. In some embodiments, one or more of the seats of the convertible furniture may articulate in concert with one another between the seat configuration and the bed configuration.

(18) Referring now to FIGS. 1 and 2, a piece of convertible furniture 10 is provided in accordance with the present disclosure in a seat configuration thereof. The convertible furniture 10 includes a base 12, a backrest 14, and arms 16 that remain fixed and may provide support for or house components of the convertible furniture 10 that articulate relative to the base 12. The convertible furniture 10 may include removable cushions (not shown) that rest on the backrest 14 and conceal articulatable components in the seat configuration of the convertible furniture 10. The convertible furniture 10 may also include one or more pillows or cushions that rest adjacent the arms 16. The removable cushions may increase comfort of the convertible furniture 10 in the seat configuration thereof. As shown the convertible furniture 10 includes a first seat 100 and a second seat 200 that are independently articulatable between the seat configuration and a bed configuration thereof.

(19) With additional reference to FIG. 3 which illustrates the convertible furniture 10 with the first seat 100 in the bed configuration thereof. The components of the first seat 100 and the second seat 200 are detailed below with respect to first seat 100 with similar components represented with similar labels with the leading 1 of the components of the first seat 100 replaced with a leading 2 for the component of the second seat 200. The first seat 100 includes articulatable components including a first or a head panel 120, a second or mid-panel 130 (FIG. 11), and a third or foot panel 140. Each of the head panel 120, the mid-panel 130, and the foot panel 140 include a cushion secured thereto that is configured to act as a mattress in a bed configuration of the first seat 100. In the seat configuration, the cushion 142 of the foot panel 140 forms a seat of the first seat 100 which is substantially horizontal in orientation. In the bed configuration, the foot panel 140 is in a deployed position that is furthest from the backrest 14 and is in a substantially horizontal orientation. The foot panel 140 may be supported in the bed configuration by a foldable frame 150 which described in greater detail below.

(20) The mid-panel 130 is in a deployed position between the head panel 120 and the foot panel 140 in the bed configuration as shown in FIG. 3. In the bed configuration, the mid-panel 130 is substantially horizontal in orientation and may be supported in the bed configuration by the foldable frame 150 and/or the base 12. The mid-panel 130 is hinged to the foot panel 140 such that the foot panel 140 rotates relative to the foot panel 140 such that in the stored position of the mid-panel 130, the mid-panel 130 is inverted and positioned below the foot panel 140 in a substantially horizontal orientation as shown in FIGS. 1 and 2.

(21) Referring now to FIGS. 1-4, in the seat configuration, the head panel 120 is in a stored position and received or nested within the backrest 14 in a substantially vertical orientation. With particular reference to FIG. 4, in an intermediate configuration, between the seat configuration and the bed configuration, the foot panel 140 and the mid-panel 130 are in a deployed position and the head panel 120 remains in its stored position nested within the backrest 14. As shown, the head panel 120 is hinged to the base 12 such that the head panel 120 folds down to a substantially horizontal orientation in its deployed position such that the first seat 100 is in the bed configuration as shown in FIG. 3. In the bed configuration, the head panel 120 is supported by the base 12 and the mid-panel 130 as described in greater detail below.

(22) With particular reference to FIG. 3, the convertible furniture 10 includes a first seat 100 and a second seat 200 that are independently articulatable between the bed configuration (first seat 100) and the seat configuration (seat 200). When both the first seat 100 and the second seat 200 are in the bed configuration, a gap G may be defined between the mid-panel 130 and the foot panel 140 of the first seat 100 and the mid-panel 230 and the foot panel 240 of the second seat 200. It may be beneficial to minimize or eliminate this gap G. Minimizing or eliminating this gap G may increase comfort in a bed configuration and/or increase safety by preventing items or appendages from being captured between the mid-panels 130, 230 and the foot panels 140, 240.

(23) Referring now to FIGS. 5-7, a gap closing mechanism 160, 260 is described in accordance with the present disclosure. Each seat 100, 200 of the convertible furniture 10 may include a gap closing mechanism 160, 260 with like elements represented with similar labels. As such, only the gap closing mechanism 260 of the second seat 200 will be detailed herein for reasons of brevity. The gap closing mechanisms 160, 260 are configured to reduce or eliminate the gap G between the mid-panels 130, 230 and the foot panels 140, 240 by urging the respective mid-panels 130, 230 and foot panels 140, 240 towards one another.

(24) With particular reference to FIG. 6, the gap closing mechanism 260 includes a dome 264 that is secured to the arm 16 adjacent a pivot bar 254 of the frame 250 of the second seat 200. The pivot bar 254 is secured to the arm 16 and a mid-support 252 that is positioned between and parallel to the arms 16. The pivot bar 254 may extend the width of the convertible furniture 10 such that the pivot bar 254 of the second seat 200 is the same bar as the pivot bar 154 of the first seat. The mid-panel 230 is rotatably and slidably secured to the pivot bar 254. Specifically, the mid-panel 230 is rotatable about the pivot bar 254 and is slidable in a transverse direction towards or away from a respective arm 16. The mid-panel 230 may be fixed in a longitudinal direction, e.g., in a direction that extends between a front and a back of the base 12. The pivot bar 254 may be secured slightly below and behind a center of the dome 264 such that the mid-panel is positioned below the dome 264 as shown in FIG. 6.

(25) As the mid-panel 230 is rotated or deployed from the seat configuration to the bed configuration, the mid-panel 230 rotates about the pivot bar 254 such that a contact portion 232 of the mid-panel 230 contacts the dome 264 to urge the mid-panel 230 away from the arm 16 and towards the mid-panel 130 of the first seat 100 as shown in FIG. 6. As the mid-panel 230 is urged away from the arm 16, the gap G is closed or eliminated. The contact portion 232 of the mid-panel 230 may include a contact insert 233 to reduce wear on the mid-panel 230 (shown as contact insert 133 in FIG. 11) and may increase a width of the mid-panel 230 towards the arm 16. The increased width may further reduce the gap G. In some embodiments, the mid-panel 230 is provided without a contact insert 233. In some embodiments, urging the mid-panel 230 may be preventing the mid-panel from moving towards the arm 16 by the dome 264 without moving the mid-panel 230 away from the arm 16.

(26) The dome 264 may be secured to the arm 16 by a fastener 265 that extends through the dome 264 to fix the dome 264 to the arm 16. The fastener 265 may fix the dome 264 to the arm 16 or may allow the dome 264 to rotate about the fastener 264 as the mid-panel 230 contacts the dome 264. The dome 264 may extend from the arm 16 in a range of 0.125 inches to 1.5 inches, e.g., 0.375, 0.5, 0.75, 1, or 1.25 inches. In some embodiments where one of the seats 100, 200 is not adjacent an arm, e.g., arm 16, the dome 264 may be secured to a center support of the base 12 to urge the respective seat 100, 200 towards the other seat 100, 200.

(27) With reference to FIGS. 2 and 8-10 the convertible furniture 10 includes a head panel support structure 170, 270 provided in accordance with the present disclosure. Each seat 100, 200 of the convertible furniture 10 includes similar features with similar elements represented with similar labels. With particular reference to FIG. 2, and noted above, in the seat configuration and the intermediate configuration the head panel 120 is in a substantially vertical orientation and nested within the backrest 14 of the convertible furniture 10. The head panel 120 has an arm tab 122, a center tab 124, a center recess 126, and a front edge 128. The head panel 120 also includes a rear edge 129 that is hinged to a rear support 19 of the base 14. The rear edge 129 may be hinged by one or more hinges that support and fix the head panel 120 to rotate from being nested within the backrest 14 (FIG. 3) to a substantially horizontal orientation as shown in FIG. 4. In the horizontal orientation, the top of the cushion of the head panel 120 is substantially co-planar with the top of the cushion of the mid-panel 130 and the foot panel 140.

(28) In the horizontal orientation, the head panel 120 is supported by the hinge on the rear edge 129, by the arm tab 122, by the center tab 124, and by the front edge 128. Supporting the head panel 120 by the arm tab 122 and the center tab 124 may prevent the weight on the front edge 128 of the head panel 120 from rotating the mid-panel 130 towards the stored position. Specifically, without the arm tab 122 and the center tab 124 supporting the head panel 120 as detailed below, it may be possible for the head panel 120 to urge the mid-panel 130 towards the stored position which may be disconcerting to a person sitting on the convertible furniture in the bed configuration.

(29) The arm tab 122 of the head panel 120 extends from the head panel 120 towards the arm 16 as shown in FIG. 3. The arm tab 122 is positioned below a top of the arm 16. In the horizontal orientation, the arm tab 122 is supported on a side rail 17 of the base 12 that is secured to the arm 16 (FIGS. 7 and 8). Having the arm tab 122 extend towards the arm 16 allows for a space S between the head panel 120 and the arm 16. The space S allows for clearance between the head panel 120 and the arm 16 as the head panel 120 is rotated towards the horizontal orientation. In some embodiments, the arm 16 may include cavity to accommodate rotation of the arm tab 122 as the head panel 120 is rotated towards or away from the horizontal orientation. In embodiments, in the horizontal position, only the arm tab 122 of the head panel 120 rest on the side rail 17 to support the head panel 120. In some embodiments, no other portion of the head panel 120 contacts or rests on the side rail 17 other than the arm tab 12 in the horizontal position.

(30) The inside edge of the head panel 120 which is opposite the arm 16 includes the center tab 124 and may include a center recess (not shown). The center tab 124 is offset from the center recess. The center tab 124 extends from the head panel 120 and supports the head panel 120 on a center support 15 of the base 12 when the head panel 120 is in the deployed position. The center recess is sized and dimensioned to accommodate a center tab 226 of the adjacent head panel 220. In embodiments, in the horizontal position, only the center tab 124 of the head panel 120 rest on the center support 15 to support the head panel 120. In some embodiments, no other portion of the head panel 120 contacts or rests on the center support 15 other than the center tab 124 in the horizontal position.

(31) The front edge 128 of the head panel 120 is supported by a head panel support 138 that is secured to mid-panel 130. The head panel support 138 extends rearward from the mid-panel 130 when the mid-panel 130 is in the deployed position as shown in FIGS. 8-10. Referring briefly back to FIG. 2, the head panel 120 is substantially rectangular in shape with the arm tab 122 and the center tab 124 extending laterally from sides of the head panel 120.

(32) Referring now to FIG. 11, the convertible furniture 10 may include a biasing mechanism 180 that assists in deploying the seat 100, 200 from the seat configuration to the bed configuration and/or assists in a soft close during storing of the seat 100, 200 from the bed configuration to the seat configuration. As shown, the biasing mechanism 180 includes a torsion spring 182 that is disposed about the pivot bar 154 of the folding frame 150. The torsion spring 182 includes a first leg 184, a body 186, and a second leg 188. The body 186 includes one or more coils 187 that wrap around the pivot bar 154. The first leg 184 extends from the body 186 and is engaged with the dome 164. In some embodiments, the first leg 184 is received within a channel 166 defined by the dome 164. The second leg 188 is engaged with a bottom surface of the mid-panel 130. In certain embodiments, the mid-panel 130 may include an insert or reinforcement 133 to reinforce the surface of the mid-panel 130 and to prevent damage to the mid-panel 130. The insert 133 may also function as the contact insert 133 for contacting the dome 164 in the deployed position thereof as described with respect to the gap adjustment mechanism 170.

(33) As shown, the biasing mechanism 180 may assist in deployment of the mid-panel 130 from the stored position to the deployed position. The biasing mechanism 180 may urge the mid-panel 130 from its stored position towards its deployed position. The biasing mechanism 180 may provide a force that aids in the rotation of the mid-panel 130 about the pivot bar 154 such that the mid-panel 130 is urged towards the deployed position. In embodiments, the biasing mechanism 180 may provide a force for only part of the deployment of the mid-panel 130. For example, the biasing mechanism 180 may provide a force to urge the mid-panel 130 towards the deployed position until the mid-panel 130 is at or beyond an over center position for the respective seat 100, 200 by being rotated in a range of 300 to 1350 about the pivot bar 154 from the stored position, e.g., until the mid-panel is rotated 45-90. Once the mid-panel 130 is rotated beyond the over center position of the respective seat 100, 200, gravity may assist in further rotation of the mid-panel 130 its deployed position.

(34) In certain embodiments, the biasing mechanism 180 may slow rotation of the mid-panel 130 towards the stored position thereof to assist with a slow close. For example, once the mid-panel 130 reaches an over center position, the biasing mechanism 180 may slow the rotation of the mid-panel 130 towards the stored position by urging the mid-panel 130 towards the deployed position thereof. While the biasing mechanism 180 urges the mid-panel 130 towards the deployed position, the force provided by the biasing mechanism 180 may be insufficient to overcome the effects of gravity but enough to slow rotation of the mid-panel 130 such that rotation of the mid-panel 130 towards the stored position is slowed but not prevented. The biasing mechanism 180 may slow the rotation of the mid-panel 130 once the mid-panel reaches a range of 45 to 135 of rotation from the stored position.

(35) Urging the mid-panel 130 towards the deployed position thereof may aid in the deployment of the mid-panel 130 and the foot panel 140 from the stored position to the deployed position thereof. Aiding the deployment of the mid-panel 130 and the foot panel 140 may reduce a force required to deploy the mid-panel 130 and the foot panel 140. Reducing the force required to deploy the mid-panel 130 may allow for single hand deployment of the foot panel 140 and the mid-panel 130. Slowing rotation of the mid-panel 130 towards the stored position may increase control of the mid-panel 130 and the foot panel 140 as the mid-panel 130 and the foot panel 140 are moved towards the stored position thereof.

(36) With reference now to FIGS. 12-14, the folding frame 150 is described with respect to the first seat 100. The folding frame 150 is folded between the mid-panel 130 and the foot panel 140 in the seat configuration and supports the foot panel 140 and the mid-panel in the bed configuration. The folding frame 150 includes a hinge 152, the pivot bar 154, a rear leg 156, and a front leg 158. The hinge 152 is secured to the mid-panel 130 and the foot panel 140 to hingedly secure the mid-panel 130 and the foot panel 140. The folding frame 150 further includes a rear link 157 that is pivotally connected at a first end to a rear wing of the hinge 152 that is secured to the mid-panel 130 and that is pivotally connected at a second end to the rear leg 156. The rear leg 156 is pivotally connected at a top end to a front wing of the hinge 152 that is secured to the foot panel 140. The folding frame 150 also includes a front link 159 that is secured on a first end to the rear leg 156 and that is pivotally secured to the top of the front leg 158. The top of the front leg 158 being pivotally connected to the bottom of the foot panel 140. The mid-panel 130 is rotatably secured to the pivot bar 154 by one or more brackets 155 that allow the mid-panel 130 to rotate about the pivot bar 154 and may allow the mid-panel 130 to translate in a direction along a longitudinal axis of the pivot bar 154. The front link 159 and/or the rear link 157 may be disposed between the front leg 158 and the rear leg 156. The geometry of the folding frame 150 may allow for a single-handed deployment or storage of the mid-panel 130 and the foot panel 140. One or both of the front legs 158 and the rear legs 156 may include a crossbar that extends between the pair of front legs 158 and the pair of rear legs 156.

(37) With particular reference to FIG. 12, in the seat configuration of the seat 100, the front leg 158 and the rear leg 156 are longitudinally folded between the mid-panel 130 and the foot panel 140. A bottom of the front leg 158 may oppose a bottom of the rear leg 156 such that the front leg 158 and the rear leg 156 are aligned in a folded position thereof. In the folded position, a user may grasp a handle 148 (FIG. 4) that is secured to the front of the foot panel 140 to move the foot panel 140 and the mid-panel 130 towards a deployed configuration thereof.

(38) Referring now to FIG. 13, as a user pulls the foot panel 140 from its stored position (FIG. 12) towards the deployed position (FIG. 14). As the foot panel 140 is lifted by a front of the foot panel 140, the mid-panel 130 rotates about the pivot bar 154 such that the mid-panel 130 is inverted about the pivot bar 154. As the mid-panel 130 rotates about the pivot bar 154, the gap closing mechanism 160 may urge the mid-panel 130 away from the arm 16 and/or the biasing mechanism 180 may assist in rotation of the mid-panel 130 as detailed above. As the mid-panel 130 approaches its deployed position, the rear link 157 rotates the rear leg 156 from the stored position towards a support position. As the rear leg 156 is rotated rearward towards its support position, the front link 159 is drawn rearward which draws the top of the front leg 158 rearward to rotate the front leg 158 towards the support position.

(39) With particular reference to FIG. 14, when the foot panel 140 and the mid-panel 130 approach the deployed position, the front leg 158 and the rear leg 156 achieve the support position in which the front leg 158 and the rear leg 156 are substantially vertical to support the foot panel 140 in the deployed position. In the deployed position, the mid-panel 130 may be supported by the base 12 near a mid-point of the mid-panel 130 and at a front edge thereof by the rear leg 156 as shown in FIG. 14. The folding frame 150 operates in reverse to return the front leg 158 and the rear leg 156 to the folded position as the foot panel 140 and the mid-panel 130 are returned to the stored position.

(40) While several embodiments of the disclosure have been shown in the drawings, it is not intended that the disclosure be limited thereto, as it is intended that the disclosure be as broad in scope as the art will allow and that the specification be read likewise. Any combination of the above embodiments is also envisioned and is within the scope of the appended claims. Therefore, the above description should not be construed as limiting, but merely as exemplifications of particular embodiments. Those skilled in the art will envision other modifications within the scope of the claims appended hereto.
