Abstract
An assembly includes a seating unit, and a pair of legs. The legs each engage and support a bottom of the seating unit, and include a protruding attachment member that slides mateably into a pocket in a rear of the seating unit. When the fasteners are installed, the protruding attachment member cannot be removed from the pocket. By this arrangement, the protruding attachment member and pocket form part of a retaining structure for retaining the leg to the seating unit. A back screen releasably fits between the leg and the back, and is retained by the protruding attachment member against the back. The screen can be shipped disassembled from the seating unit, and assembled on site to provide a privacy function while complimenting the chair's architectural appearance.
Description




BACKGROUND




The present invention relates to seating units designed for comfort, privacy, and efficient assembly, and more particularly relates to a lounge chair having a releasably attached back screen and legs, either one of which can be shipped in a knocked-down condition and assembled on site. Notably, it is contemplated that the present invention is not limited just to lounge chairs.




Lounge chairs are often used in public areas, such as in airports, business lobbies, and common areas in office buildings, to provide comfortable open seating. However, even in public areas, users often want a degree of visual privacy so that they can socialize and/or work with a sense of enclosure. A problem is that most lounge chairs are not intended and do not provide good visual privacy, since they have relatively low backs and arms, and also they are often placed away from building walls. As a result, people moving around will often come up on a seated person's backside and be able to disturb their activity or concentration. It is desirable to provide lounge chairs that are flexibly constructed to satisfy a wide range of visual privacy needs without major compromise of the seating elements. Further, it is desirable that the level of privacy be able to be specified to fit the customer's application.




In addition to and as part of the above, it is desirable to provide a chair assembly that can be knocked down and shipped as a dense package. At the same time, on-site assembly of components must be very easy, require few tools, involve few pieces, and provide a low chance of damaging chair components during on-site in-the-field assembly.




Another challenge is that many consumers want a high-quality, modern architectural “look” with flat surfaces, sharp lines, and “clean, crisp” edges and joints. Flat surfaces, sharp linear lines, and “clean, crisp” edges are not easily made consistent unless a sturdy support frame is provided for cushions, since cushion edges tend to break down and collapse over time, particularly with heavy use. However, sturdy support frames can be expensive. Still further, consumers want the ability to arrange and rearrange the seating units in different patterns, which requires not only light weight but also a style that permits chairs to be arranged in a range of configurations. It is not immediately apparent how to combine these different functional requirements into a single seating system, nor how to satisfy the need for rearrangeability.




Accordingly, an article and method are desired solving the aforementioned problems and having the aforementioned advantages.




SUMMARY OF THE PRESENT INVENTION




In one aspect of the present invention, a seating unit assembly includes a seating unit, and a leg engaging a bottom and a back of the seating unit. The leg includes a protruding attachment member that releasably engages a pocket in the seating unit when the leg is attached to the seating unit. At least one fastener attaches the leg to the seating unit at a location spaced from the protruding attachment member so that, when the fastener is installed, the protruding attachment member cannot be removed from the pocket. By this arrangement, the protruding attachment member and pocket form part of a retaining structure for retaining the seating unit to the leg.




In another aspect of the present invention, a seating unit assembly includes a seating unit, and a leg attached to and supporting the seating unit. A back screen is attached to the seating unit and retained, at least in part, by the leg. The back screen extends upwardly from a rear of the seating unit so that the back screen visually shields a seated person in the seating unit when the seating unit is viewed from a position behind the chair.




In yet another aspect of the present invention, a method of shipping and assembling a seating unit comprises steps of providing a seating unit having a rear, providing a leg shaped to support the seating unit and including an attachment member oriented to releasably engage the rear, and providing a back screen shaped to lie against the rear and fit between the rear and the attachment member. The method further includes shipping the back screen in a condition unattached to the seating unit, positioning the back screen against the rear of the seating unit and between the seating unit and the attachment member, and attaching the leg to the seating unit to, at least in part, hold the back screen in position on the seating unit.




In yet another aspect of the present invention, a method includes steps of providing a seating unit with a back portion, and attaching a back screen to the back portion that extends above the back portion to create a visual screen that separates a seated user from persons behind the seating unit.




These and other aspects, objects, and features of the present invention will be understood and appreciated by those skilled in the art upon studying the following specification, claims, and appended drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS




A lounge chair (also hereafter called a seating unit assembly


20


) (

FIG. 1

) includes a seating unit


21


, and a pair of legs


22


. The legs


22


each include a flat portion


23


(

FIG. 5

) interconnected by transverse channels


23


′ that engage and support a bottom of the seating unit


21


, and further include a protruding attachment member


24


with an end that slides mateably into a pocket


25


in the back of the seating unit


21


. Two pairs of threaded fasteners


26


attach the leg


22


to a bottom of the seating unit


21


. When the fasteners


26


are installed, the protruding attachment member


24


cannot be removed from the pocket


25


. By this arrangement, the protruding attachment member


24


and pocket


25


form part of a retaining structure for retaining the legs


22


to the seating unit


21


. A back screen


27


is provided that can be optionally fit against a rear of the seating unit


21


between the legs


22


and the back of the seating unit


21


. The back screen


27


is retained by the protruding attachment member


24


against the back. The arrangement permits the back screen


27


to be shipped in a knocked-down condition separate from the seating unit


21


, and to be selectively assembled on site. Additionally, attachment of the back screen


27


further provides a very distinctive alternative appearance, as well as provides the function of partial screening around the seating unit assembly


20


.




The illustrated seating unit


21


includes thick cushions to provide a lounge-type seating often found in reception areas, public areas, meeting areas, and the like. However, it is contemplated that many of the present concepts, such as the back screen concept and the one-screw leg attachment concept, can be used in a wide variety of situations, such as on office chairs, public seating, and the like.




The seating unit


21


includes a seat portion


31


and a back portion


32


. The seat portion


31


includes a seat frame


33


(

FIG. 7

) that supports a seat cushion


34


(

FIG. 3

) upholstered onto the frame


33


, and the back portion


32


(

FIG. 8

) includes a back frame


35


that supports a back cushion


36


(

FIG. 3

) upholstered onto the frame


35


. The seat portion


31


and the back portion


32


have box-like shapes, and include multiple flat surfaces with relatively square and sharp corners, which provides a clean and crisp appearance sometimes referred to as “an architectural look”. It is noted that the panel-like back screen


27


, when attached to the back, compliments this architectural look.




The seat frame


33


(

FIG. 7

) is made of a plurality of wooden or composite boards, including top and bottom apertured panels


37


and


38


, interconnected by front and rear boards


39


and


40


, and by a plurality of horizontal cross supports


41


-


45


. All components


37


-


45


include tongues and mating grooves that inter-fit together (FIG.


9


). The assembly is secured by mechanical and/or adhesive means, such as by staples, nails, glue, or other ways known in the art. Additionally, the bottom apertured panel


38


includes holes and inserted T-nuts


46


for receiving the fasteners


26


.




The back frame


35


(

FIG. 8

) is also made of a plurality of wooden or composite boards, and includes a rear apertured panel


48


, top and bottom boards


49


and


50


, and by a plurality of vertical cross supports


51


-


54


. A secondary board


55


is attached to panel


48


for stiffening, and also board


55


covers pocket


25


to prevent member


24


from traveling through pocket


25


. Most components


48


-


54


include tongues and mating grooves that inter-fit together, although this is not required, per se. The assembly is secured by mechanical and/or adhesive means, such as by staples, nails, glue, or other ways known in the art. Additionally, the rear apertured panel


48


includes the holes forming the pockets


25


, which pockets are covered on a cushion-side front surface by cross supports


52


and


53


to limit over-travel of the attachment members


24


through the pockets


25


.




It is noted that the frame


33


/


35


can be made longer for bench-type multi-person seating by extending a length of the seat and back frames. In such case, the seat and back frames include additional cross supports as needed, and additional legs are attached as desired.




The “linear” seating unit assembly


20


can be modified to become a corner seating unit assembly


20


A modifying the back frame


33


/


35


and by addition of a corner-forming back frame


35


B. The illustrated corner seating unit assembly


20


A (

FIG. 12

) utilizes tongue-and-grooved seat and back frames


33


A and


35


A that are very similar to the seat and back frames


33


and


35


of the linear seating unit assembly


20


(FIG.


10


), but edges of the seat and back frames


33


A and


35


A are modified to mate with the corner-forming back frame


35


B. The corner-forming back frame


35


B includes a rear apertured panel


48


B, top and bottom boards


49


B and


50


B, and by a plurality of vertical cross supports


51


B-


53


B. The illustrated components


48


B-


53


B include tongues and mating grooves that inter-fit together. The assembly is retained together and to seat and back frames


33


B and


35


B by known means, such as staples, nails, and glue. A corner back cushion is supported on a front of the corner back frame


32


B.




The illustrated legs


22


(

FIG. 3

) are each a weldment of two bent J-shaped tubular sections and two channels


23


′. The tubular sections include a flat portion


23


with a downwardly formed front end section


58


, and also include an upright portion


59


with a lower/rear end section


59


′ and a forwardly bent top end section. Glides


60


′ are attached to the front and rear end sections


58


and


59


for engaging a floor surface. The protruding attachment member


24


is integrally formed from a front end of the top end section of the upright portion


59


, and is oriented in a forward horizontal direction so that it engages the pocket


25


as the flat portion


23


engages and supports the bottom surface of the seat portion


31


. Notably, the protruding attachment member


24


is at a slight angle to the flat portion


23


, so that as the leg


22


is slid forwardly with the seating unit


21


resting on the flat portion


23


, the attachment member


24


gradually engages the marginal material forming the pocket


25


with increasing downward force. By this arrangement, the back frame


35


is drawn against the leg


22


during assembly for secure retention. In turn, once the fastener screws


26


are installed through the legs


22


into the nuts


46


, the seating unit


21


is secured to each leg


22


at both front and rear locations. It is contemplated that as many legs


22


can be attached to each seating unit


21


as are desired for the expected loading and use (or abuse) expected for the seating unit. In the illustrated arrangement, the leg


22


includes a washer or steel grommet


60


(

FIG. 3

) welded to the protruding attachment member


24


at a location so that it limits movement of the attachment member


24


into the pocket


25


and further so that it distributes stress around this joint to the back frame


35


.




The illustrated back screen


27


(

FIG. 2

) is a flat panel, such as a wood product (pressboard or plywood, for example), covered with upholstery or other covering. The back screen


27


includes a pair of holes


61


shaped to receive the attachment member


24


when the legs


22


are positioned for attachment. The illustrated back screen


27


includes a zipper


62


along two sides to facilitate adding the covering material over the back screen


27


, but it is contemplated that a variety of different covering techniques can be used. For example, it is contemplated that back screens can be painted, stained, or otherwise covered instead of upholstered. Further, the back screen does not have to be a panel made of a wood product, but instead can be a translucent, transparent or opaque plastic, metal, composite, or other stiff material, and further can include a perimeter frame supporting an air-permeable screening material. The illustrated back screen


27


also includes a recess for receiving the washer


60


so that the washer


60


is located flush with the back when fully installed and attached. The particular back screen


27


shown is advantageous in that the lines formed by the back screen


27


are long and extend parallel existing lines on the seating unit assembly


20


. Thus, the back screen


27


compliments the architectural look of the seating unit assembly


20


.




To attach the back screen


27


, screws


26


are loosened and legs


22


are moved rearwardly relative to the seating unit


21


, (with the seating unit


21


still potentially resting on the legs


22


). The back screen


27


is slipped between the upright portion of the legs


22


and screen


27


is slipped between the upright portion of the legs


22


and against a rear of the seating unit


21


. The legs


22


are then moved forward with the protruding attachment members


24


being extended through the apertures


61


in the back screen


27


and into the pockets


25


in the seating unit


21


. The fasteners


26


are then used to secure the legs


22


to the seating unit


21


, with the back screen


27


clamped in place.




It is noted that the back screen


27


provides significant privacy for a person seated in the seating unit assemblies


20


. This privacy is further extended through use of adjacently-positioned seating unit assemblies


20


with back screens


27


. For example, as shown in

FIG. 11

, a pair of the linear seating unit assemblies


20


can be positioned on opposite sides of a table


70


to form a booth-like arrangement. The booth arrangement can be positioned next to an office partition or wall for additional privacy. The booth arrangement as shown is highly usable in an office common area, for example, where it is desirable to continue an architectural appearance, yet provide privacy and/or an invitation to group discussion. The illustrated table


70


has a rectangular top


71


, which further is consistent with an architectural theme.





FIG. 12

illustrates a larger furniture arrangement, such as may be used in an airport waiting area or larger office building. The arrangement utilizes one linear seating unit assembly


20


, two back-screened corner seating unit assemblies


20


B, and two no-screen corner seating unit assemblies


20


B′ to form a well-defined and semi-enclosed area. More specifically, one linear seating unit assembly


20


is positioned between two corner seating unit assemblies


20


B, with each having a back screen


27


attached. The back screens


27


form a continuous visual shield across a back of the row of seating unit assemblies


20


and


20


B. One additional corner seating unit assembly


20


B′ is positioned at each end to close off the ends. These additional corner seating unit assemblies


20


B′ do not include any back screens


27


, such that they provide a more open appearance on the ends of the row. The seating unit assemblies


20


,


20


B and


20


B′ form an elongated C-shaped arrangement. By positioning another similar arrangement in front of the first such furniture arrangement, a well-defined area is formed where a person coming into the area can easily see who is in the area, but where the “new” person cannot see over the back screens. In yet another arrangement (see the dashed lines in FIG.


12


), two corner units can be provided with back screens


27


(see dashed lines), but an opening


75


still occurs to provide a controlled level of viewing into the area of concern.
