CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit, under 35 U.S.C. § 119(e), of U.S. Provisional Patent Applications Serial Nos. 60/576,855 filed on June 3, 2004, and 60/576,868 filed on June 3, 2004, both of which are hereby incorporated by reference herein.

BACKGROUND OF THE INVENTION The present disclosure relates to adaptable clinical environments, and particularly to a modular system for constructing walls in a clinical environment. Conventional methods for constructing walls in a healthcare facility utilize timber, steel and dry wall which are more or less permanently secured to the floor and/or the ceiling of the healthcare facility. Such traditional methods of construction involve long and unreliable construction times due to the difficulties in scheduling the various craftsmen such as carpenters, painters, plumbers, electricians and the like to complete the construction work. The rooms and spaces constructed using such traditional methods are not readily reconfigurable. Any such reconfiguration requires tearing down the existing walls. Such reconfiguration is not only costly, time consuming and disruptive, but produces a lot of dirt, dust and noise. The material that is removed is generally not reusable, and has to be disposed of. Modular wall systems for dividing open spaces into cubicles and rooms are well known. Examples of such systems are disclosed in U.S. Patent Publication No. US 2002/0104271 and U.S. Patent No. 6,405,491, both of which are entitled "Modular Patient Room."

SUMMARY OF THE INVENTION The present invention comprises a system that has one or more of the following features or combinations thereof, which alone or in any combination may comprise patentable subj ect matter. A system for constructing walls may include a plurality of frame units having connection points and a plurality of family zone modules coupled to the frame units at the connection points to form a wall. The frame units may form a grid of vertically and laterally spaced apart connection points having a predetermined vertical spacing and a predetermined lateral spacing. At least some of the plurality of family zone modules may have a width substantially equal to a multiple, including one, of the predetermined lateral spacing and a height substantially equal to a multiple, including one, of the predetermined vertical spacing. Some examples of family zone modules are a visitor hideaway bed module, a microwave module, a refrigerator module, a cabinet module, a drawer module, a foldout seat module, a reading lamp module, a television module, a shelving module, a wardrobe module, a decorative panel module, a whiteboard module, a tacksurface module and a mood panel module. It will be understood that this list is only illustrative, and not intended to be exhaustive. Additional features, which alone or in combination with any other feature(s), such as those listed above in the appended claims, may comprise patentable subject matter and will become apparent to those skilled in the art upon consideration of the following detailed description of various embodiments exemplifying the best mode of carrying out the embodiments as presently perceived.

DETAILED DESCRIPTION OF THE DRAWINGS Figs. 1 and 2 show a modular system 20 for constructing walls. Illustratively, the modular wall system 20 includes a plurality of infrastructure components 22 and a plurality of modules, such as the family zone modules 24, coupled to the infrastructure components 22 to form a wall 26. Such a system 20 may, for example, be used for constructing walls in a healthcare facility such as a private patient room 28. Referring to Fig. 1, the family zone modules 24 illustratively include a hideaway bed module 200 (as best shown in Fig. 3), a microwave module 202 (as best shown in Fig. 4), a refrigerator module 204 (as best shown in Fig. 5), a cabinet module 206 (as best shown in Fig. 6), a drawer module 208 (as best shown in Figs. 7, 8), a fold-down seat module 210 (as best shown in Fig. 9), a reading lamp module 212 (as best shown in Fig. 10), a television module 214, a fold-down worksurface module 216, a shelving module 218, a wardrobe module 220, a decorative panel module 222, a whiteboard module 224, a tacksurface module 226 and a mood panel module 228. It will be understood that this list is only illustrative, and not intended to be exhaustive. Also shown in Fig. 1 are a chair 230 resting on a floor 152 in the family area of the patient room 28 and a window 232 in a conventional wall 160 near to the family area of the patient room 28. It should be understood that although the illustrative wall 26 shown in Fig. 1 includes a plurality of family zone modules 24, the modular wall may very well include other module types such as, for example, patient care modules, footwall modules, clinical wall modules, hygiene zone modules and the like (not shown). Some examples of the patient care modules are a vital signs module, a service delivery module, a bed locator module, a monitor module, a viewbox module, a sharps disposal module, a computer/keyboard module, a tube drop module, a waste management module, a light module, and a clock module. Such patient care modules are disclosed in Serial No. PCT/US2005/xxxxxx, entitled "Patient Care Modules for Hospital Walls," (attorney docket no. 7175-78002) which is assigned to the same assignee as the subject application and which is hereby incorporated by reference herein. The term "hospital equipment module" is used broadly, and includes a patient care module, a footwall module, a clinical wall module, a family zone module, a hygiene zone module, a door module, a window module, a fold-out bed module, a vital signs module, an equipment storage module, and the like. As shown in Fig. 2, the infrastructure components 22 include frame units 100 and a plurality of supporting members 102. hi the illustrated embodiment, the supporting members 102 are hangers configured to be detachably coupled to the frame units 100. Each frame unit 100 includes a pair of vertical members 110 and a pair of horizontal members 112 extending between the vertical members 110 near the top and the bottom of the frame units 100 to form a generally rectangular structure with an open space or cavity 114 in the middle that extends between the front and back sides 116, 118 of the frame unit 100. Illustratively, the vertical and horizontal members 110, 112 are made from tubular members having generally rectangular cross section. The vertical members 110 of each frame unit 100 have a first plurality of connection points 120 facing the front side 116 of the frame unit 100 and a second plurality of connection points 120 facing the back side 118 of the frame unit 100. hi the illustrated embodiment, the first plurality of connection points 120 is a first plurality of hanger-receiving openings 120 extending along the depth dimension and facing the front side 116 of the frame unit 100. Likewise, the second plurality of connection points 120 is a second plurality of hanger-receiving openings 120 extending along the depth dimension and facing the back side 118 of the frame unit 100. The hanger-receiving openings 120 are sized and shaped to receive the hangers 102. When inserted, the hangers 102 fit into in the hanger-receiving openings 120 in the frame units 100 so that they firmly lock in place. Illustratively, both the hangers 102 and the hanger-receiving openings 120 are generally rectangular in cross section. The hangers 102 extend generally horizontally away from the frame units 100 in a cantilevered fashion. As explained below, the lengths of the hangers 102 generally match the depth of the respective modules 24 supported by such hangers 102. The center-to-center lateral spacing 130 between the hanger-receiving openings 120 in the vertical members 110 of each frame unit 100 along the width dimension or the x-axis is fixed. Illustratively, the center-to-center lateral spacing 130 between the hanger-receiving openings 120 is about 2 feet (about 60 centimeters). The center-to-center vertical 132 spacing between the hanger-receiving openings 120 in the vertical members 110 of each frame unit 100 along the height dimension or the z-axis is also fixed. Illustratively, the center-to-center spacing 132 between the hanger-receiving openings 120 along the height dimension is about 2 feet (about 60 centimeters). Thus, the first and second plurality of hanger-receiving openings 120 are spaced apart from each other by a predetermined width 130 and a predetermined height 132 to form 2 feet-by-2 feet (about 60 centimeters-by-60 centimeters) grids on the opposite sides 116, 118 of the frame units 100. Each module 24 has a width substantially equal to a discrete multiple, including one, of the predetermined width (2 feet or about 0.60 meter in the illustrated example) and a height substantially equal to a discrete multiple, including one, of the predetermined height (2 feet or about 0.60 meter in the illustrated example). In the embodiment illustrated in Fig. 2, a first plurality of modules 24 is supported by the hangers 102 on the front side 116 of the frame units 100. A second plurality of modules 24 is supported by hangers 102 on the back side 118 of the frame units 100. As shown in Fig. 11, each module 24 includes a pair of oppositely disposed guide tracks or channels 140 near the upper end of the module 24 and a pair of oppositely disposed guide tracks or channels 140 near the lower end of the module 24. The upper and lower pairs of guide tracks 140 slidably receive the corresponding hangers 102 secured to the vertical members 110 of the frame units 100. The guide tracks 140 and the hangers 102 are sized to provide a sliding fit. Suitable latches are used for securing the modules 24 to the hangers 102. The lower horizontal member 112 of each frame unit 100 has a pair of vertically extending through openings 150 for securing the frame unit 100 to the floor 152 of the healthcare facility. Likewise, the upper horizontal member 112 of each frame unit 100 has a pair of vertically extending through openings 150 for securing the frame unit 100 to the ceiling 154 of the healthcare facility where the frame unit 100 extends from the floor 152 to the ceiling 154. Any suitable fasteners 156, such as studs, pins, screws or nuts and bolts, may be used for securing the frame units 100 to the floor 152 and to the ceiling 154. hi the illustrated embodiment, the frame units 100 are secured to a base board 158, instead of the floor 152, so that the modules 24 can be protected, for example, from mops, floor cleaning equipment etc. The base board 158 is, in turn, secured to the floor 152. Illustratively, the base board 158 is about 4 inches (10.16 centimeters) high. hi the illustrative embodiment, each frame unit 100 is coupled to the adjoining frame units 100 on either side thereof. In addition, the frame unit 100 closest to an existing conventional wall 160 of the healthcare facility is secured thereto. To this end, the vertical members 110 of each frame unit 100 have a plurality of laterally extending through openings 162. Any suitable fasteners 164, such as studs, pins, screws or nuts and bolts, may be used for securing each frame unit 100 to the adjoining frame units 100 on the opposite sides thereof and to the adjoining existing wall 160. Utility lines 172 may be routed from the mechanical room of the healthcare facility into the patient room 28. These utility lines 172 may typically be routed through one of the floor 152, the ceiling 154 or the wall 26 of the patient room 28. The horizontal members 112 have vertically extending through slots or cutouts 170 through which utility lines 172 enter the open space or the cavity 114 defined by the frame members 110, 112. The utility lines 172 are then routed from the open space 114 to the associated modules 24. Illustratively, the utility lines 172 include data lines, gas lines, vacuum lines, AC/DC power lines, hot and cold water lines and plumbing lines. hi addition, laterally extending through openings (not shown) may be formed in the vertical members 110 of the frame units 100 for passing the utility lines 172 from an open space 114 in one frame unit 100 to an open space 114 in the next adjacent frame unit 100 on either side thereof. From the open spaces 114 in the next adjacent frame units 100, the utility lines 172 are then routed to the associated modules 24. The open space 114 in the frame units 100 may be filled with sound and/or thermal insulation material. The family zone modules 24 have a width substantially equal to a discrete multiple, including one, of the predetermined lateral spacing 130 between the hanger-receiving openings 120. Illustratively, the predetermined lateral spacing 130 between the hanger-receiving openings 120 is about 2 feet (about 60 centimeters). Thus, the width of the family zone modules 24 may be about 2 feet (about 60 centimeters), 4 feet (about 120 centimeters), 6 feet (about 180 centimeters), etc. The family zone modules 24 have a height substantially equal to a discrete multiple, including one, of the predetermined vertical spacing 132 between the hanger- receiving openings 120. Illustratively, the predetermined vertical spacing 132 between the hanger-receiving openings 120 is also about 2 feet (about 60 centimeters). Thus, the height of the family zone modules 24 may be about 2 feet (about 60 centimeters), 4 feet (about 120 centimeters), 6 feet (about 180 centimeters), 8 feet (about 240 centimeters), etc. While the width and the height of the modules 24 are a discrete multiple, including one, of the predetermined lateral spacing 130 and the predetermined vertical spacing 132 between the openings 120, the depth of the modules 24 may, however, vary depending on their functionality. For example, the decorative panel modules 222 are about one inch (2.54 centimeters) deep. As previously indicated, the lengths of the hangers 102 generally match the depth of the associated modules 24 supported by said hangers 102. Thus, the length of the hangers 102 used for supporting 1 inch (2.54 centimeters) deep decorative panel modules 222 would also be about 1 inch (2.54 centimeters). Such modular wall system 20 is disclosed in PCT/US2005/xxxxxx, entitled "Modular System for Constructing Hospital Walls," (attorney docket no. 7175-78000) which is assigned to the same assignee as this application and which is hereby incorporated by reference herein. Referring to Fig. 3, the hideaway bed module 200 includes a deck 250 coupled to an enclosure or cabinet 252 for pivoting movement between an upwardly extending storage position where the deck 250 is received in a deck-receiving space or cavity 254 in the enclosure 252 and an outwardly extending use position where the deck 250 extends generally horizontally from the cabinet 252. The deck 250 is movable between the upwardly extending storage position and the outwardly extending use position in a manner similar to the movement of the well known Murphy bed. Space within a patient room is always an issue in the planning of a healthcare facility. Freestanding items within the room can become obstacles for the patient, caregivers and the visitors. The deck 250 can be moved to the out-of-the-way storage position when not in use to free the floor space for the caregivers to access the patient. The undersurface 276 of the deck 250 may have artwork so that, when the deck 250 is in the upwardly extending storage position, the artwork provides a pleasing, home-like appearance which is not likely to raise apprehension on the part of the patient or a visitor. The enclosure 252 includes a back wall 256, a pair of side walls 258 and 260, a top wall 262 and a bottom wall 264. The deck-receiving space 254 is bounded by the side walls 258, 260, the top wall 262 and the bottom wall 264. The front edges of the walls 258-264 define a forwardly facing surface 266. The deck 250 includes a head end 270, a foot end 272, an upwardly facing surface 274 (also referred to as inwardly facing surface 274) and a downwardly facing surface 276 (also referred to as outwardly facing surface 276). A mattress 278, such as, for example, an air mattress, rests on the upwardly facing surface 274 of the deck 250. A plurality of straps (not shown) secure the mattress 278 to the deck 250 to hold it in place when the deck 250 is raised to the storage position. It is understood that although straps (not shown) are used in the illustrated embodiment to secure the mattress 278 to the deck 250, other suitable fasteners may very well be used. Some example of such fasteners are Velcro strips, loop and tie fasteners, hook and eye fasteners, clips, snaps, zippers, etc. A plurality of hinges (not shown) near the head end 270 of the deck 250 couple the deck 250 to the enclosure 252 so that the deck 250 pivots relative to the cabinet 252 about a first laterally extending axis 290 between the raised storage position and the lowered use position. A retainer or latch (not shown) holds the deck 250 in the deck-receiving cavity 254 when the deck 250 is raised. In the raised storage position, the outwardly facing surface 276 of the deck 250 is generally flush with the outwardly facing surface 266 of the enclosure 252 so as to appear as a continuous part thereof. Li the lowered use position, the deck 250 extends generally outwardly from the enclosure 252. In the lowered use position, the head end 270 of the deck 250 is positioned near the back wall 256 of the enclosure 252. A foot panel 292 is pivotally coupled to the deck 250 near the foot end 272 thereof to pivot between a raised storage position where the foot panel 292 lies in a foot panel-receiving cavity 294 in the downwardly facing undersurface 276 of the deck 250 and a lowered use position where the foot panel 292 rests on the floor 152 to support the foot end 272 of the deck 250. A plurality of hinges (not shown) near the foot end 272 of the deck 250 couple the foot panel 292 to the deck 250 so that the foot panel 292 pivots relative to the deck 250 about a second laterally extending axis 296. When the foot panel 292 is received in the foot panel-receiving cavity 294 in the deck 250, an outwardly facing surface 298 of the foot panel 292 is generally coplanar with the outwardly facing surface 276 of the deck 250 so as to appear as a continuous part thereof. The foot panel 292 includes a handle 300 to enable a caregiver to move the foot panel 292 between the raised and lowered positions. A retainer or lock (not shown) holds the foot panel 292 in the foot panel- receiving cavity 294. A latch (not shown) locks the foot panel 292 in the lowered use position where the foot panel 292 rests on the floor 152 to support the foot end 272 of the deck 250. The terms "retainer", "latch" and "lock" are used interchangeably. A reading light 302 and a switch 304 are located on the back wall 256 of the enclosure 252. The switch 304 operates the reading light 302. Alternatively, in some embodiments, the reading light 302 is automatically turned on the when the deck 250 is lowered to the use position. The lower portion 306 of the enclosure 252 houses equipment such as, for example, a compressor, a motor, a controller, tubing, valves, etc. for inflating the air mattress 278. Illustratively, the enclosure 252 is about 4 feet (about 120 centimeters) wide, 8 feet (about 240 centimeters) high and 1 foot (about 30 centimeters) deep; the lower portion 306 is about 4 feet (about 120 centimeters) wide, 2 feet (about 60 centimeters) high and 1 foot (about 30 centimeters) deep; the foot panel 292 is about 2 feet (about 60 centimeters) high, and the deck 250 is about 6.5 feet (about 195 centimeters) long. When the deck 250 is lowered to a horizontal position, the head end 270 of the deck 250 extends about 1 foot (about 30 centimeters) into the enclosure 252 and the rest of the deck 250 extends about 5.5 feet (about 165 centimeters) outside the enclosure 252. The hangers 102 securing the hideaway bed module 200 to the vertical members 110 of the frame units 100 are about 2 feet (about 60 centimeters) long. It is noted that all family zone modules 24, including the hideaway bed module 200, have a width substantially equal to a discrete multiple of the predetermined lateral spacing 130 (2 feet or about 60 centimeters in the illustrated embodiment) between the hanger-receiving openings 120. Also, all family zone modules 24, including the hideaway bed module 200, have a height substantially equal to a discrete multiple of the predetermined vertical spacing 132 (2 feet or about 60 centimeters in the illustrated embodiment) between the hanger-receiving openings 120. In operation, the caregiver releases the latch holding the foot panel 292 in the foot panel-receiving cavity 294 and moves the foot panel 292 to the extended position to lock it in place. The caregiver then releases the latch holding the deck 250 in the deck-receiving cavity 254 and moves the deck 250 to the lowered use position so that the foot panel 292 rests on the floor 152 to support the foot end 272 of the deck 250. The head end 270 of the deck 250 is supported by the hinges (not shown) pivotally coupling the deck 250 to the enclosure 252. The procedure is reversed to move the deck 250 to the raised storage position. A gas spring or other such means may be provided to assist the movement of the deck 250 between the storage and use positions. In other embodiments, springs, counter balance mechanisms, hydraulic actuators, electric motor, and the like, may be used to assist the caregiver in moving the deck 250 between its storage and use positions. As indicated above, although not shown in Fig. 3, all family zone modules 24, including the hideaway bed module 200, include a pair of oppositely disposed guide tracks or channels 140 near the upper end of the modules 24 and a pair of oppositely disposed guide tracks or channels 140 near the lower end of the modules 24 as shown in Fig. 11. The upper and lower pairs of guide tracks 140 slidably receive the corresponding hangers 102 secured to the vertical members 110 of the frame units 100. The guide tracks 140 and the hangers 102 are sized to provide a sliding fit. Suitable latches are used for securing the modules 24 to the hangers 102. Referring to Fig. 4, the microwave module 202 includes a cabinet or housing 320 having a back wall 322, a pair of side walls 324 and 326, a top wall 328, a bottom wall 330, an upper shelf 332 and a lower shelf 334.

As indicated above, although not shown in Figs. 3-10, each family zone module 24 includes a pair of oppositely disposed guide tracks or channels 140 near the upper end of the module 24 and a pair of oppositely disposed guide tracks or channels 140 near the lower end of the module 24 as shown in Fig. 11. The upper and lower pairs of guide tracks 140 slidably receive the corresponding hangers 102 secured to the vertical members 110 of the frame units 100. The guide tracks 140 and the hangers 102 are sized to provide a sliding fit. Suitable latches are used for securing the modules 24 to the hangers 102. Also, it will be noted that the family zone modules 24 have a width substantially equal to a discrete multiple, including one, of the predetermined lateral spacing 130 between the hanger-receiving openings 120. The family zone modules 24 have a height substantially equal to a discrete multiple, including one, of the predetermined vertical spacing 132 between the hanger-receiving openings 120. While the width and the height of the modules 24 are a discrete multiple, including one, of the predetermined lateral spacing 130 and the predetermined vertical spacing 132 between the openings 120, the depth of the modules 24 may, however, vary depending on their functionality. It will be noted that many of the family zone modules 24 can also be used to form a footwall of the patient room. The footwall zone modules are designed around the needs of the patient as it relates to his or her belongings, information and entertainment. Thus, examples of family zone modules 24 that can also be used as footwall zone modules are, for example, cabinet module 206, drawer modules 208, television module 214, shelving module 218, decorative panel module 222, whiteboard module 224, tacksurface module 226 and mood panel module 228.
