Broadly, embodiments of the present invention provide a modular furniture system that divides the sofa into modules that can be combined with a modular coffee table at will to achieve the desired furniture configuration. The sofa modules have foldable armrests and there are storage spaces under both the sofa modules and the modular coffee table. The modules can be put together using connectors to make a sofa bed. The modular coffee table can also be taken out separately to form a double sofa and coffee table, or the coffee table can be expanded to become an ottoman. Each of the sofa modules can be taken out separately and used as an armchair.

The figures are briefly described below, followed by a broader discussion of each figure and the components therein.

The front and rear orthogonal views of the coffee table are shown in FIGS. 1A through 1C. One of the things to note is that underneath the top plate of the coffee table are two layers of sofa foam cushions, with a section of the foam cushions sewn together. To ensure that the coffee table can be kept level during use, a rotating bracket and a lock that can be pushed in and pulled out (as shown in FIG. 3A) were added to the end that is sewn together. In addition, there is a shelf at the bottom of the side table that can be extended, and drawers on the lower front side of FIG. 1A for storage.

FIGS. 2A and 2B are more detailed views of the coffee table module of FIG. 1A. The top of the lock cylinder is a semi-circular groove that holds the bracket securely when the bracket is fully vertical.

FIGS. 3A and 3B show the unfolding process of the coffee table. After the lock cylinder is fully pushed in, the holder can be rotated to the bottom slot.

FIG. 4 shows the fully expanded coffee table. After the top cushion is unfolded, the original top plate of the coffee table can fit perfectly into the slot of the bracket. This state can be used not only as part of the sofa bed but also as an ottoman.

FIG. 5 is an exploded view of all parts of the modular coffee table. The shelf can be pulled out by pulleys and rails, for example (drawer-type construction).

FIGS. 6A and 6B show the unfolding process of the modular coffee table. Where the first step pushes in the lock cores on both sides; the second part puts down the brackets on both sides; the third part pulls out the shelf; the fourth part unfolds the upper sofa cushion.

FIGS. 7A through 7C show the unexpanded state of the single-seater sofa module. There are two foldable armrests on both sides of the sofa, and the armrests consist of two rods and armrest cushions. The lower side of the armrest rod can rotate around the axis of the sofa body, while the upper side can slide freely in the internal slots of the armrest cushion. The armrest cushion can be stuck when sliding to the highest position, as shown. The lower part of the sofa also has storage space. In the comfort angle, the sofa backrest has a certain tilt angle (about 2-3°). FIG. 7C shows the details of the sofa backrest latch. The back cushions of the sofa have a support plate behind which a brace for support in the unfolded mode is hidden.

FIG. 8 shows a side view of the sofa, where the sofa backrest maintains a certain angle of inclination because a section of it slides in a designed slide.

The fully expanded mode of the sofa is shown in FIGS. 9A and 9B.

FIGS. 10A and 10B show a side view of the sofa in fully expanded mode, with a detail of the slide of the sofa backrest on the right.

FIGS. 11A and 11B show an exploded view of the sofa, which shows in detail the position and shape of the various parts of the sofa.

FIG. 12 shows the exploded view of the sofa in the side view, whereas the detail view shows the shape of the backrest rails in detail.

FIGS. 13A through 13C show the unfolding process of the sofa. In the first step, the armrests are lowered; in the second step, the back lock is unlocked; in the third step, the support is unfolded; in the fourth step, the sofa cushion is lowered; in the fifth step, the sofa cushion is adjusted to a completely horizontal position along the rails; finally, the lock in the second step is tightened.

The sofa bed form is shown in FIG. 14. The coffee table module can be placed in the middle or on either side (FIG. 14 only shows the case of one side). The lower drawer can be fully opened for storage. The sofa module is connected to the other modules by connectors.

FIGS. 15A and 15B show the shape and mounting position of the connectors. The connector is U-shaped, with a slightly locked open end with a projection, which can be kept in place by micro-deformation after insertion.

FIG. 16 shows a double single sofa (armchairs) sitting in pair mode.

FIGS. 17A and 17B show the loveseat mode and the mounting position of the connectors.

FIGS. 18A and 18B show the loveseat with ottoman mode.

The above FIG. 14 through FIG. 18B only show the centralized possible centralized unfolding mode, which may be combined into more forms in real life by various modules (e.g., three-seater sofa, or the like).

Referring specifically to FIGS. 1 through 6D, a coffee table module 10 (also referred to as coffee table 10 or ottoman 10, when the module is opened) can include a front side 12, a back side 14, a top surface 16 and sides 18. Legs 20 may extend from a channel 22 formed in a base portion 24 of the coffee table module 10 to permit the top surface 16 to rest against the expanded legs 20 when the coffee table module 10 is expended into the ottoman configuration (as shown, for example, in FIG. 4A. A drawer 36 may be extendable from a front side 12 of the coffee table 12. In some embodiments, the drawer 36 may nest alongside with the legs 20 when in the coffee table configuration as shown in FIG. 1A.

A lock arm 26 may extend from the base 24 to fit into the top surface 16 when the coffee table module 10 is in the coffee table configuration as shown in FIG. 1A. As shown in FIGS. 6A through 6D, the user can depress a lock button 28 to permit the lock arm 26 to pivot about pivot axis 30, where the lock arm 26 may then fit into a slot 34 formed in the base 24 of the coffee table module 10. Such movement of the lock arm 26 can permit the top member 16A, including the top surface 16, to be opened to rest against the legs 20, this forming the ottoman configuration, where cushions 38 form the upper surface thereof. As described above, the cushions 38 may be sewn together along one seam 32 to form a pivot axis.

Referring now to FIGS. 7A through 13D, a sofa module 40 can include a base portion 46 having a base cushion 44 mounted thereupon. A back member 50 may pivotably attach to the base portion 46 at pivot axis 73. A back cushion 42 may be mounted on the back member 50. A storage drawer 52 may extend from the front of the back portion 46. Of course, the drawer may extend from a side or the back 48 of the base member 46.

Arms 60 may be movable between deployed configurations and stored configurations. FIG. 7A shows one arm deployed and one stored. The arms 60 may attach to support rods 62. Various mechanisms may be used to move the arms between the deployed and stored positions. For example, the support rods 62 may pivotably attach to the base portion 46, while the support rods 62 may slide on the bottom side of the arms 60, permitting the movement between the stored and deployed positions. Other mechanisms may also be used. For example, the support rods may slide down into the base portion 46 when the arms 60 are in the stored configuration.

Legs 54 may be formed within the back member 50. In some embodiments, the legs 54 may rest substantially flush with the back plane of the back member 50 when the sofa module 40 is in the chair configuration, as shown in FIG. 7B. The legs 54 may pivot outward about a pivot axis 70 to permit the back member 50 to be positioned horizontally with the legs 54 contacting a floor surface. A release tab 56 may move a release member 56A out of a portion of the back member 50 to permit the movement of the back member down into the bed configuration, as shown in FIG. 10A, for example.

As the back member 50 is pivoted downward, the back cushion 42 can include slot 74 into which a tab 72 of the back member 50 can fit to slide the back cushion 42 against the base cushion 44 when in the bed configuration. A rail 68 can be provided on which a tab 66 of the back member 50 slides. The rail 68 may be in an elongated U-shape, where each end of the U-shape may hold the sofa member 40 in either the seat configuration (FIG. 8, for example) or in the bed configuration (FIG. 10A, for example). FIG. 13D shows the movement of the back member 50 along the slide 68 for converting the back member 50 between the bed and sofa configurations.

Referring now to FIGS. 14 through 18B, the sofa modules 40 and the coffee table module 10 can be disposed in various configurations. Front slots 82 may receive connectors 80 to secure the modules 40, 10 together. Similar, bottom slots 86 may receive connectors 84 to secure the modules 40, 10 together. FIGS. 14, 15A and 15B illustrate one possible interconnection to form a sofa bed. While the coffee table module 10 is shown on one end, this module may be placed on an end or in a central position, if desired. One arm rest may be opened to create a partial headboard and/or footboard for the sofa bed, if desired. FIG. 16 shows the sofa modules 40 forming armchairs with the coffee table module 10, in the coffee table configuration, therebetween. FIGS. 17A and 17B show the sofa modules 40 attached together, using the same slots 82, 86 and connectors 80, 84, described above, to form a loveseat, with the coffee table module 10 in a coffee table configuration. FIGS. 18A and 18B show the sofa modules 40 attached together, using the same slots 82, 86 and connectors 80, 84, described above, to form a loveseat, with the coffee table module 10 in an ottoman configuration.
