## Title
Composite assembly of interconnectable furniture

## Abstract

A composite assembly of furniture units each have a solo utilization, which can be seating surface area or table top surface area. The furniture units are made with an irregular contoured surface. When the irregular surface of a first furniture unit is brought in proximity to the irregular surface of a second furniture unit, the composite assembly assumes a joint utilization which differentiates from the solo utilization of the furniture units. The joint utilization of the composite assembly enlarges seating surface area or the table top surface area over the solo utilization. The furniture units are versatile because each can be used in its solo configuration or combined into the composite assembly for other uses. A mechanical coupling mechanism is used to secure the furniture units in the composite assembly configuration. The mechanical coupling can be a latch, magnetic plate, bracket, or rod.

No. 7,237,845, issued Jul. 3, 2007, entitled “Furniture Designed for Sitting and Having Inner Core Support Assembly”. The present patent application is further related to U.S. patent application Ser. No. 11/059,162, now U.S. Pat. No. 7,131,699, issued Nov. 7, 2006, entitled “Furniture with Seating Space and Entertainment Center”.
FIELD OF THE INVENTION
The present invention relates in general to furniture and furnishings, more particularly, to a composite assembly of interconnectable furniture units.
BACKGROUND OF THE INVENTION
Furniture can be found in virtually every home, business, office, and many outdoor settings. Furniture performs a variety of useful functions such as providing seating places and surfaces for placing items thereon. Some furniture is designed and constructed for one person to use. For example, a single chair is intended to comfortably support the weight and form of one person. Other types of furniture are compatible with multiple users. A sofa or sectional will easily accommodate more than one person.
When the end user, e.g., homeowner or business owner, is planning for the purchase and placement of furniture in their particular environment, many factors are carefully considered such as function, usage, style, price, etc. Assume the end user is planning a backyard furniture arrangement for entertaining and relaxing. The user may decide on an outdoor dining table and set of 4-6 individual chairs around the table. In addition, the user may want a few chase lounges, recliners, and rockers with ottomans, as well as some coffee tables and end tables. Each piece of furniture has a specific dedicated purpose and generally cannot be interchanged for another function.
Consider the case of the outdoor dining table and chair set. The outdoor dining set is intended to stay together and provide a table surface for food and entertaining and chairs for seating around the table. To pull one or more chairs away from the outdoor dining set, for another long term and entirely different purpose, separate from the dining set, is considered undesirable and poor form to many users. Likewise, the idea of moving just the table to another location for an extended period of time is equally rejected by many users. Most outdoor furniture has a single functional purpose and usually stays with that purpose over its useful service life.
With the single mindset of maintaining dedicated pieces of furniture, the user must plan and purchase additional furniture units for each specific use and setting. The user may have some furniture pieces for the patio, other furniture pieces around the outdoor fire pit, still other furniture positioned around the pool, and so on. Some pieces are designed and constructed for one person to use; other pieces are built for multiple users. The single dedicated-purpose furniture adds significant cost to the task of furnishing the home, office, or outdoor setting. The user needs many different pieces to cover all intended uses. Many times certain dedicated pieces are rarely used, but nonetheless remain in their assigned location just in case the need arises.
A need exists for furniture which can have multiple uses in a variety of configurations and situations.
SUMMARY OF THE INVENTION
In one embodiment, the present invention is a plurality of furniture units, comprising a first furniture unit having an irregular surface. A second furniture unit has an irregular surface. The first and second furniture units each have a solo utilization. The first and second furniture units have a joint utilization when the irregular surface of the first furniture unit is disposed in proximity to the irregular surface of the second furniture unit.
In another embodiment, the present invention is an article of furniture, comprising first and furniture units each having a solo utilization. The first and second furniture units have a joint utilization which differentiates from the solo utilizations of the first and second furniture units when the first furniture unit is disposed in proximity to the second furniture unit.
In another embodiment, the present invention is a composite assembly of furniture units, comprising a first furniture unit having a solo utilization. A second furniture unit has a solo utilization. A means for combining the first and second furniture units provides a joint utilization of the first and second furniture units which differentiates from the solo utilizations of the first and second furniture units.
In another embodiment, the present invention is a method of making an article of furniture, comprising providing a first furniture unit having a solo utilization, providing a second furniture unit having a solo utilization, and providing a joint utilization of the first and second furniture units which differentiates from the solo utilizations of the first and second furniture units when the first furniture unit is disposed in proximity to the second furniture unit.

DETAILED DESCRIPTION OF THE DRAWINGS
The present invention is described in one or more embodiments in the following description with reference to the Figures, in which like numerals represent the same or similar elements. While the invention is described in terms of the best mode for achieving the invention's objectives, it will be appreciated by those skilled in the art that it is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims and their equivalents as supported by the following disclosure and drawings.
Referring to FIG. 1a, an article of furniture 10 is designed and constructed for sitting purposes and shown as suitable for supporting the weight and form of one or more adult persons. Furniture unit 10 is useful for many applications including home, office, industry, and outdoor spaces. Furniture unit 10 is durable, inexpensive, and may be used in settings such as office waiting rooms, employee break rooms, and family room in the home. Furniture unit 10 is ideal for outdoor uses such as on the patio, under the gazebo, and around the pool for relaxing and entertaining.
Furniture unit 10 has upper portion 12 designed to support the weight and form of one or more adults. Furniture unit 10 may have an inner core assembly with a foam or padded covering. The inner core assembly is disclosed herein. The upper portion 12 rests on frame or support base 14, which contacts the ground on at least the four corners of the unit. Furniture unit 10 may be 36 inches wide by 90 inches long by 20 inches in height. The long sides 16 and 18 of furniture unit 10 have an irregular shape. In the embodiment shown in FIG. 1a, the long sides 16 and 18 have a contoured, curved, or S-shape. The contoured shape, while visually interesting and appealing to observers, provides a useful function in the context of the present invention.
Turning to FIG. 1b, article of furniture 20 is designed and constructed for sitting purposes and shown as suitable for supporting the weight and form of one or more adult persons. Furniture unit 20 has upper portion 22 which may contain a similar inner core assembly with a foam or padded covering. The upper portion 22 rests on a frame or support base 24, which contact the ground on at least the four corners of the unit. Furniture unit 20 may be 36 inches wide by 90 inches long by 20 inches in height. The long sides 26 and 28 of furniture unit 20 have an irregular shape. In the embodiment shown in FIG. 1b, the long sides 26 and 28 have a contoured, curved, or S-shape. Again, the contoured shape, while visually interesting and appealing to some observers, provides a useful function in the context of the present invention.
Furniture units 10 and 20 can be used separate and independent of one another for their intended purpose. Each furniture unit is a stand-alone unit and has a solo utility or utilization. In the case of furniture units 10 and 20, the solo utilization is separate sitting and lounging. The user can position furniture unit 10 is a first location, e.g., on the patio, and then sit on upper portion 12, possibly with others, independent of the utilization of furniture unit 20. The user can position furniture unit 20 is a second location, e.g., by the pool, and then sit on upper portion 22, possibly with others, independent of the utilization of furniture unit 10.
As a feature of the present invention, the articles of furniture 10 and 20 are made modular and interconnectable so that they can be brought together to form a composite assembly having joint useful features, utilities, and capabilities. FIG. 2 illustrates furniture units 10 and 20 placed side by side. Frames 14 and 24 contact the ground to support the respective units. The long side 18 of furniture unit 10 is disposed adjacent to, in contact with, or in close proximity to, the long side 26 of furniture unit 20.
Another article of furniture 30, having a similar design and construction as furniture units 10 and 20 is placed side by side with furniture unit 20. Furniture unit 30 has upper portion 32 which may contain a similar inner core assembly with a foam or padded covering. The upper portion 32 rests on frame or support base 34, which contact the ground on at least the four corners of the unit. Furniture unit 30 may be 36 inches wide by 90 inches long by 20 inches in height. The long sides 36 and 38 of furniture unit 30 have an irregular shape. In the embodiment shown in FIG. 2, the long sides 36 and 38 have a contoured, curved, or S-shape. The long side 28 of furniture unit 20 is disposed adjacent to, in contact with, or in close proximity to, the long side 36 of furniture unit 30.
The composite assembly of furniture units 10, 20, and 30 placed side by side constitutes a unique and functionally different article of furniture than the individual furniture units 10, 20, and 30 alone. The joint utility or utilization of composite assembly 10-20 functionally differentiates from the solo utilization of individual furniture units 10, 20, and 30. The composite assembly 10-30 has a greater surface area and weight carrying capacity than the individual furniture units 10-30 alone. The composite assembly 10-30 is about 108 by 90 inches. The composite assembly 10-30 can be used by one or more persons to spread out, lay on, or sun bathe. The larger area of composite assembly is ideal as a sleeping surface, play area for children and infants, area to play games, and gathering place for teenagers, which is clean, safe, and off the ground. The above exemplary joint utilization of the composite assembly cannot practically or conveniently be achieved with the solo utilization of the individual furniture units 10, 20, and 30. The user may find many other purposes for the larger surface area provided by the joint utilization of the composite assembly 10-30.
In one embodiment, the furniture units 10-30 are brought together and maintain their close proximity by nature of the mass inertia of the units. The weight of the furniture units and coefficient of static friction of the support bases to the ground keep the units together as the composite assembly.
In another embodiment, the furniture units 10-30 can be mechanically coupled together for additional strength and rigidity of the composite assembly. FIGS. 3a-3e illustrate a few ways of mechanical coupling the furniture units together. In one example, the furniture units are coupled together with a latching or clamping mechanism. The latching mechanism can be located in any convenient location of the respective furniture units. In FIG. 3a, the frame 14 of furniture unit 10 is shown coupled to frame 24 of furniture unit 20 with latching mechanism 40. The latching mechanism may be on one end or both ends of each furniture unit to hold the composite assembly together. In FIG. 3b, magnetic plates 42 and 44 are mounted to frames 14 and 24 of furniture units 10 and 20, respectively. When frame 14 is brought in close proximity to frame 24, the attractive magnetic forces of magnetic plates 42 and 44 will secure the furniture units together as the composite assembly. In FIG. 3c, furniture unit 10 is provided with loops 46. Likewise, furniture unit 20 is given loops 48. The loops 46 and 48 may be made of fabric, plastic, or metal. A rod 50 is routed through loops 46 and 48 as shown to secure furniture units 10 and 20 as the composite assembly. In FIG. 3d, the furniture units 10 and 20 are held together with U-shaped brace or bracket 52. The U-shaped brace 52 is made of plastic or metal and slides into openings in upper portions 12 and 22 of furniture units 10 and 20. Alternatively, the U-shaped brace 52 may also slide into openings in frames 14 and 24. In FIG. 3e, Velcro strips 54 and 54 are mounted to upper portions 12 and 22 of furniture units 10 and 20, respectively. The Velcro strips may be mounted to one or more locations along the long side of the upper portions of the furniture units. When upper portion 12 is brought into contact with upper portion 14, the Velcro strips will stick together to secure the furniture units together as the composite assembly. The above techniques of mechanically coupling the furniture units together are provided by way of example; other securing mechanisms can also be used to hold the composite assembly together.
The irregular shape of furniture 10-30 enhances the mechanical coupling between the units. The irregular shape increases the contact surface area between the furniture units and improves the shear forces against unintentional movement. If any one of the furniture units is jarred or bumped, it is less likely that the composite assembly will dislodge from its unioned state.
One advantage of the form and function of furniture units 10-30 is the versatility to use the pieces both as individual articles of furniture and as components of the composite assembly. The user need not purchase and store multiple pieces of furniture. If the user has need of separate and solo utilization of seating benches or lounges, such as shown in FIGS. 1a-1b, then furniture units are left detached and used separately. If the user needs a larger composite assembly, such as shown in FIG. 2, then the furniture units 10-30 are placed in proximity to one another and optionally mechanically coupled together. The user then has the benefit of the joint utilization of the composite assembly 10-30. The furniture units 10-30 are efficient, cost effective, and versatile.
In FIG. 4a, an article of furniture 60 is shown suitable for sitting purposes and supporting the weight and form of one or more adult persons. An article of furniture 62 is shown in FIG. 4b suitable for sitting purposes and supporting the weight and form of one or more adult persons. Furniture units 60 and 62 each have an irregular curved shape and may be constructed with an inner core assembly with foam or padded exterior as described above.
Furniture units 60 and 62 can be used separate and independent of one another for their intended purpose. Each article of furniture 60 and 62 is a stand-alone unit and has a solo utility or utilization, e.g., sitting and lounging. The furniture units 60 and 62 are made modular and interconnectable so that they can be brought together to form a composite assembly having jointly useful features, utilities, and capabilities by virtue of the combination of the individual furniture units. FIG. 5 illustrates furniture units 60 and 62 placed end to end. Another article of furniture 64, having a similar design and construction as furniture units 60 and 62, is placed end to end with furniture unit 62.
The composite assembly of furniture units 60, 62, and 64 placed end to end constitutes a unique and functionally different article of furniture having a greater surface area than the individual furniture units 60-64 alone. The composite assembly 60-64 provides a longer continuous bench area for additional seating. Additional furniture units 66 and 68 may be placed side by side with furniture units 60 and 64, respectively. The irregular surface of furniture unit 60 is placed in proximity to or in contact with the irregular surface of furniture unit 66. The irregular surface of furniture unit 64 is placed in proximity to or in contact with the irregular surface of furniture unit 68. The irregular surface area contact helps keep the composite assembly together. The composite assembly 60-68 provides a longer and, in areas, wider continuous bench area for additional seating. The curved nature of the composite assembly 60-68 provides more seating room in a given longitudinal distance and given area. The furniture units 60-68 can be mechanically coupled together for additional strength and rigidity of the composite assembly in a similar manner as described in FIGS. 3a-3e. 
The form and function of furniture units 60-68 provides the versatility to use the pieces both as individual articles of furniture and as components of the composite assembly. If the user has need of separate and solo utilization of seating benches or lounges, such as shown in FIGS. 4a-4b, then furniture units are left detached and used separately. If the user needs a larger composite assembly, such as shown in FIG. 5, then the furniture units 60-68 are placed in proximity to one another and optionally mechanically coupled together. The user then has the benefit of the joint utilization of the composite assembly 60-68. The furniture units 60-68 are efficient, cost effective, and versatile.

The furniture units 70 and 80 are made modular and interconnectable so that they can be brought together to form a composite assembly having jointly useful features, utilities, and capabilities by virtue of the combination of the individual furniture units. FIG. 7 illustrates two sets of furniture units 70 and 80 placed side by side. One joint feature of the composite assembly 70-80 is that the armrest of each furniture unit is shared with the adjacent furniture unit.
The composite assembly of furniture units 70 and 80 placed side by side constitutes a unique and functionally different article of furniture than the individual furniture units 70 and 80 alone. The joint utility or utilization of composite assembly 70-80 functionally differentiates from the solo utilization of individual furniture units 70 and 80. The composite assembly 70-80 provides a close and compact seating arrangement and allows adjacent furniture units to share armrests. The furniture units 70-90 can be mechanically coupled together for additional strength and rigidity of the composite assembly.
FIG. 8 illustrates the modular and interconnectable furniture units 70, 80, and 90 arranged three abreast in four separate groupings facing a center area.
