(f) ONE MODE FOR CARRYING OUT THE INVENTION
As can be seen by reference to the drawings, and in particularly to FIG. l, the collapsible support surface and seating appal ~lus that forms the basis of the present invention is de~i~n~ted generally by the reference number 10. The appal~lus 10 comprises in general, a desk unit 11, a desk support unit 12, and a seat unit 13. These units will now be described in seriatim fashion.
As shown in FIGS. l through 4, the desk unit 11 comprises an enlarged generally rectangular one-piece desk member 20 having a top surface 21, and a bottom surface 22 provided with a pair of elongated channel track elements 23 disposed in a parallel and spaced apart relationship relative to one another. The purpose and function of the channel track elements 23 will be explained presently.
219213~
poo7 72FI APP 8 As can best be seen by reference to FIGS. 3 and 4, the desk support unit 12 comprises two pairs 30,30 and 31,31 of support legs that are operatively associated with the bottom surface 22 of the desk member 20 and pivotally secured to one another as at 32,32 proximate their respective midpoints.
The first pair of support legs 30,30 are pivotally and fixedly secured on their upper ends 33 to the bottom surface 22 of the desk member 20. The second pair ofsupport legs 31,31 are pivotally and movably connected on their upper ends 34,34within the channel track elements 23 for reasons that will be explained in greater detail further on in the specification.
As caIl be appreciated particularly by lerel-ellce to FIG. 3, the first pair of support legs 30, 30 are subst~nti~lly straighter and longer than the second pair of support legs 31, 31. The upper and intermediate portions ofthe support legs 30,30 are relatively closely spaced and parallel to one another. The lower portion of the support legs 30,30 are slightly outwardly flared and connected to one another by a relatively short cross-piece member 35.
Still referring to FIG. 3, it can be seen that the second pair of support legs 31,31 have a contoured configuration incl~l~ing a slightly inwardly flared intermediate portion and a substantially outwardly flared lower portion wherein the lower portions of the support legs 31, 31 are connected to one another by an elongated contoured cross-piece member 36 having an outwardly bowed intermediate portion dimensioned to accommodate the lower portion of the first pair of support legs 30, 30 when the apparatus 10 is disposed in the collapsed mode.
Returning once more to FIGS. 3 and 4, it can be seen that the seat unit 13 comprises in general a seat member 40 provided with a pair of contoured seat support arms 41, 41 which are fixedly secured on their outboard ends to the seat member 40 and are pivotally secured on their inner ends as at 42,42 to the intermediate portion of the first pair of support legs 30, 30.
21921~4 pO0772FI APP 9 In addition, the seat unit 13 further inçl~ldes an angled brace element 43 which is pivotally secured on its lower end to the intermediate portions of the contoured seat support arms 41,41 and which is pivotally secured on its upper end as at 45 to the bottom surface 22 of the desk member 20.
At this juncture, it should be noted that in the pl~Çel-ed embodiment of the invention depicted in FIG. 4, both the pivoted connection of the upper end of the angled brace element 43 and the upper ends of the first pair of support legs 30, 30 areaccomplished via an intermediary pair of contoured support arms 50, 50 which arerigidly secured to the bottom surface 22 of the desk member 20. Whereas, the intermediary pair of contoured support arms 50,50 are provided primarily for thepurpose of providing rigidity and support to the desk member 20. It is to be understood that individual conventional pivot support structures (not shown) could be substituted therefor, and still fall within the teaçhing~ of this invention.
It should further be noted by reference to FIG. 4, that the first 30, 30 and second 31,31 pairs of support legs are normally biased into their open disposition by a pair of spring elements 38 which are in operative contact with adjacPnt pairs of support legs at their pivoted connection 32 to f~.ilit~te the transition ofthe appa~aLLls 10 from the collapsed mode of FIGS. 2 and 7 to the operative mode of FIGS. 5 and 6.
In addition, a handle member 60 is rigidly affixed to the bottom surface 22 of the desk member 20 to f~cilitate the transport ofthe appal~LLIs 10 from one location to another. A pair of stop elements 25,25 are positioned adjacent the open end of the channel track elements 23,23 to prevent the second pair of support legs 31,31 from becoming disengaged with the channel track elements 23,23.
As can best be seen by reference to FIGS. 1 through 3, the first pair of table support legs 30, 30 are subst~nti~lly longer than the second pair of support legs 31, 31 for the simple reason that the seat unit 13 must be cantilevered out from the desk member 20 in its operative mode of disposition. Furthermore, while the upper ends of the first pair of table support legs 30,30 are connected to the underside 22 of the desk member 20 in a straightforward pivoted fashion, the upper ends of the second pair of 2I 92~I3~
Poo772FlApP 1 0 support legs 31, 31 are both pivotally and movably disposed in the channel trackelements 23 so that the second pair of support legs 31, 31 can be tr~n~l~ted from the storage position of FIGS. 3 and 4 to the operative position of FIGS. 5 and 6.
When the appalaLLIs 10 is in the fully collapsed mode depicted in FIG. 7, the 5 width of the apparatus 10 equals the combined width of the outer pair of support legs 31 plus the thickness of the desk member 20. This exceptionally slim profile is made possible both by the nesting contour of the structural components illustrated in FIGS. 3 and 4, as well as the unique moveable pivot arrangement produced by the channel track elements 23.
Since the plilll~y purpose and function ofthe apparatus 10 is in a classroom environment, this invention also contemplates the provision of a removable and/or retractable privacy screen 60 as depicted in phantom in FIG. 5.
As can be seen by reference to the drawings, and in particular to FIG. 8, the collapsible support surface and seating appala~lls that forms the basis of the present invention is design~ted generally by the reference numeral 110. The appal~ s 110comprises in general, a table unit 111, a table support unit 112, and a chair unit 113.
These units will now be described in seriatim fashion.
As shown in FIGS. 8 thru 12, the table unit 111 comprises a pair oftable top halves 120 and 121 wherein one table top half 120 is fixedly secured on the outboard end of a first pair of outer generally straight table support arms 122 and the other table top half 121 is fixedly secured on the outboard end of a second pair of inner contoured table support arms 123.
In addition, as can best be seen by reference to Fig. 12, the outerboard ends ofboth pairs of table support arms 122, 123 substantially overlap the inboard ends of each other to provide substantial underlying support to the table top halves 120, 121.
Referring to FIGS. 10 thru 12, it can be seen that the table support unit 112 comprises a first pair of outer elongated contoured support legs 132 and a second pair of inner contoured support legs 133 wherein the first and second pairs of support legs 132 and 133 are pivotally secured to one another as at 131. In addition, each pair of support 219213~
legs 132 and 133 have a flared portion disposed proximate to, but spaced from, their lower ends. The lower ends of each pair of support legs 132 and 133 are provided with ~li~e.~ g cross piece member 134; and, a handle element 135 is disposed on a cross-piece element 136 which extends between the upper portion ofthe support legs 133.
As can best be seen by reference to FIGS. 2 and 4, the free ends of the generally straight support arms 122 are pivotally secured to the upper ends of the elongated pair of support legs 133 and the free ends of the contoured table support arms 123 are pivotally connected to the upper ends of the support legs 132.
As shown in FIGS. 8 thru 12, the seat unit 113 comprises a pair of seat members 140 wherein each seat member 140 is fixedly secured to the outboard ends of a pair of contoured seat support arms 141 wherein the inboard ends of the seat support arms 141 are pivotally secured to the elongated support legs 132 and 133 respectfully. In addition, an angled seat brace element 142 has a lower end plvotally secured to the interme.1i~te portion of the seat support arms 141 and an upper end pivotally secured to the contoured table support arms 122.
As can best be appreciated by reference to FIGS. 2 through 5, both pairs of support legs 132,133, the seat support arms 41 and the contoured table support arms 123 have the same general overall configuration which incllldes a somewhat narrow parallel portion, and outwardly flared intermediate portion and a generally wide parallel portion wherein the contoured portions are dimensioned and d~signed to cooperate with one another in a generally nesting fashion to produce the smallest possible storage profile for the combined table and chair apparatus 110.
To that end the upper portion of the seat brace element 142 nests between the contoured table support arms 123. The contoured table support arrns 123 nest between the seat support arms 141 and the table support legs 132. The relatively elongated table support legs 132 nest between the relatively short table support legs 133. Furthermore, all of the support arms and legs, as well as the brace ~l~m~nt, have the same width and all of the pivoted connections are vertically aligned when the combined table and chair appa~ s 110 is disposed in the collapsed mode as shown in FIG. 9.
219213~
po~77ZFIAPP 1 2 Accordingly, the total width ofthe plerelled version ofthe table and chair apparatus equals the combined width of the support legs 132,133 plus the combined thickness of both table top halves 120 and 121, which is the smallest possible structural storage profile that can be achieved for a two piece collapsible table let alone the 5 combined table and chair apparatus that forms the basis of the present invention.
In the alternate version ofthe prerel,ed embodiment depicted in FIGS. 13 and 14, a structural difference involves an auxiliary leg assembly 150 comprising a pair of relatively short auxiliary leg members 151 and 152 wherein the auxiliary leg members 151,152 ate pivotally connected to one another on their lower ends; and, pivotally connected on their upper ends relatively to the pairs of support legs 132 and 133 proximate the pivoted connection of the seat support arms 141 with the support legs 132,133.
It should also be noted that each of the auxiliary leg members 151 and 152 comprise a pair of contoured leg elements wherein the pair of leg elements of auxiliary 15 leg members 151 are dimensioned to be received within the pair of leg elements of auxiliary leg member 152.
It should further be noted that the pl erel l ed embodiment of the invention depicted in FIGS. 8 thru 12 is designed for use with children; whereas, the alternate version depicted in FIGS. 6 and 7 is designed for adults and requires the presence of the 20 auxiliary leg assembly. Furthermore, as shown in the dashed line portion of FIG. 3, this invention also contemplates the provision of stepped shoulders 138 on each pair of support legs 132,133 such that the stepped shoulders 138 may serve as a foot rest for the users.

(f) ONE MODE FOR CARRYING OUT THE INVENTION
As can be seen by reference to the drawings, and in particularly to FIG. l, the collapsible support surface and seating appal ~lus that forms the basis of the present invention is de~i~n~ted generally by the reference number 10. The appal~lus 10 comprises in general, a desk unit 11, a desk support unit 12, and a seat unit 13. These units will now be described in seriatim fashion.
As shown in FIGS. l through 4, the desk unit 11 comprises an enlarged generally rectangular one-piece desk member 20 having a top surface 21, and a bottom surface 22 provided with a pair of elongated channel track elements 23 disposed in a parallel and spaced apart relationship relative to one another. The purpose and function of the channel track elements 23 will be explained presently.
219213~
poo7 72FI APP 8 As can best be seen by reference to FIGS. 3 and 4, the desk support unit 12 comprises two pairs 30,30 and 31,31 of support legs that are operatively associated with the bottom surface 22 of the desk member 20 and pivotally secured to one another as at 32,32 proximate their respective midpoints.
The first pair of support legs 30,30 are pivotally and fixedly secured on their upper ends 33 to the bottom surface 22 of the desk member 20. The second pair ofsupport legs 31,31 are pivotally and movably connected on their upper ends 34,34within the channel track elements 23 for reasons that will be explained in greater detail further on in the specification.
As caIl be appreciated particularly by lerel-ellce to FIG. 3, the first pair of support legs 30, 30 are subst~nti~lly straighter and longer than the second pair of support legs 31, 31. The upper and intermediate portions ofthe support legs 30,30 are relatively closely spaced and parallel to one another. The lower portion of the support legs 30,30 are slightly outwardly flared and connected to one another by a relatively short cross-piece member 35.
Still referring to FIG. 3, it can be seen that the second pair of support legs 31,31 have a contoured configuration incl~l~ing a slightly inwardly flared intermediate portion and a substantially outwardly flared lower portion wherein the lower portions of the support legs 31, 31 are connected to one another by an elongated contoured cross-piece member 36 having an outwardly bowed intermediate portion dimensioned to accommodate the lower portion of the first pair of support legs 30, 30 when the apparatus 10 is disposed in the collapsed mode.
Returning once more to FIGS. 3 and 4, it can be seen that the seat unit 13 comprises in general a seat member 40 provided with a pair of contoured seat support arms 41, 41 which are fixedly secured on their outboard ends to the seat member 40 and are pivotally secured on their inner ends as at 42,42 to the intermediate portion of the first pair of support legs 30, 30.
21921~4 pO0772FI APP 9 In addition, the seat unit 13 further inçl~ldes an angled brace element 43 which is pivotally secured on its lower end to the intermediate portions of the contoured seat support arms 41,41 and which is pivotally secured on its upper end as at 45 to the bottom surface 22 of the desk member 20.
At this juncture, it should be noted that in the pl~Çel-ed embodiment of the invention depicted in FIG. 4, both the pivoted connection of the upper end of the angled brace element 43 and the upper ends of the first pair of support legs 30, 30 areaccomplished via an intermediary pair of contoured support arms 50, 50 which arerigidly secured to the bottom surface 22 of the desk member 20. Whereas, the intermediary pair of contoured support arms 50,50 are provided primarily for thepurpose of providing rigidity and support to the desk member 20. It is to be understood that individual conventional pivot support structures (not shown) could be substituted therefor, and still fall within the teaçhing~ of this invention.
It should further be noted by reference to FIG. 4, that the first 30, 30 and second 31,31 pairs of support legs are normally biased into their open disposition by a pair of spring elements 38 which are in operative contact with adjacPnt pairs of support legs at their pivoted connection 32 to f~.ilit~te the transition ofthe appa~aLLls 10 from the collapsed mode of FIGS. 2 and 7 to the operative mode of FIGS. 5 and 6.
In addition, a handle member 60 is rigidly affixed to the bottom surface 22 of the desk member 20 to f~cilitate the transport ofthe appal~LLIs 10 from one location to another. A pair of stop elements 25,25 are positioned adjacent the open end of the channel track elements 23,23 to prevent the second pair of support legs 31,31 from becoming disengaged with the channel track elements 23,23.
As can best be seen by reference to FIGS. 1 through 3, the first pair of table support legs 30, 30 are subst~nti~lly longer than the second pair of support legs 31, 31 for the simple reason that the seat unit 13 must be cantilevered out from the desk member 20 in its operative mode of disposition. Furthermore, while the upper ends of the first pair of table support legs 30,30 are connected to the underside 22 of the desk member 20 in a straightforward pivoted fashion, the upper ends of the second pair of 2I 92~I3~
Poo772FlApP 1 0 support legs 31, 31 are both pivotally and movably disposed in the channel trackelements 23 so that the second pair of support legs 31, 31 can be tr~n~l~ted from the storage position of FIGS. 3 and 4 to the operative position of FIGS. 5 and 6.
When the appalaLLIs 10 is in the fully collapsed mode depicted in FIG. 7, the 5 width of the apparatus 10 equals the combined width of the outer pair of support legs 31 plus the thickness of the desk member 20. This exceptionally slim profile is made possible both by the nesting contour of the structural components illustrated in FIGS. 3 and 4, as well as the unique moveable pivot arrangement produced by the channel track elements 23.
Since the plilll~y purpose and function ofthe apparatus 10 is in a classroom environment, this invention also contemplates the provision of a removable and/or retractable privacy screen 60 as depicted in phantom in FIG. 5.
As can be seen by reference to the drawings, and in particular to FIG. 8, the collapsible support surface and seating appala~lls that forms the basis of the present invention is design~ted generally by the reference numeral 110. The appal~ s 110comprises in general, a table unit 111, a table support unit 112, and a chair unit 113.
These units will now be described in seriatim fashion.
As shown in FIGS. 8 thru 12, the table unit 111 comprises a pair oftable top halves 120 and 121 wherein one table top half 120 is fixedly secured on the outboard end of a first pair of outer generally straight table support arms 122 and the other table top half 121 is fixedly secured on the outboard end of a second pair of inner contoured table support arms 123.
In addition, as can best be seen by reference to Fig. 12, the outerboard ends ofboth pairs of table support arms 122, 123 substantially overlap the inboard ends of each other to provide substantial underlying support to the table top halves 120, 121.
Referring to FIGS. 10 thru 12, it can be seen that the table support unit 112 comprises a first pair of outer elongated contoured support legs 132 and a second pair of inner contoured support legs 133 wherein the first and second pairs of support legs 132 and 133 are pivotally secured to one another as at 131. In addition, each pair of support 219213~
legs 132 and 133 have a flared portion disposed proximate to, but spaced from, their lower ends. The lower ends of each pair of support legs 132 and 133 are provided with ~li~e.~ g cross piece member 134; and, a handle element 135 is disposed on a cross-piece element 136 which extends between the upper portion ofthe support legs 133.
As can best be seen by reference to FIGS. 2 and 4, the free ends of the generally straight support arms 122 are pivotally secured to the upper ends of the elongated pair of support legs 133 and the free ends of the contoured table support arms 123 are pivotally connected to the upper ends of the support legs 132.
As shown in FIGS. 8 thru 12, the seat unit 113 comprises a pair of seat members 140 wherein each seat member 140 is fixedly secured to the outboard ends of a pair of contoured seat support arms 141 wherein the inboard ends of the seat support arms 141 are pivotally secured to the elongated support legs 132 and 133 respectfully. In addition, an angled seat brace element 142 has a lower end plvotally secured to the interme.1i~te portion of the seat support arms 141 and an upper end pivotally secured to the contoured table support arms 122.
As can best be appreciated by reference to FIGS. 2 through 5, both pairs of support legs 132,133, the seat support arms 41 and the contoured table support arms 123 have the same general overall configuration which incllldes a somewhat narrow parallel portion, and outwardly flared intermediate portion and a generally wide parallel portion wherein the contoured portions are dimensioned and d~signed to cooperate with one another in a generally nesting fashion to produce the smallest possible storage profile for the combined table and chair apparatus 110.
To that end the upper portion of the seat brace element 142 nests between the contoured table support arms 123. The contoured table support arrns 123 nest between the seat support arms 141 and the table support legs 132. The relatively elongated table support legs 132 nest between the relatively short table support legs 133. Furthermore, all of the support arms and legs, as well as the brace ~l~m~nt, have the same width and all of the pivoted connections are vertically aligned when the combined table and chair appa~ s 110 is disposed in the collapsed mode as shown in FIG. 9.
219213~
po~77ZFIAPP 1 2 Accordingly, the total width ofthe plerelled version ofthe table and chair apparatus equals the combined width of the support legs 132,133 plus the combined thickness of both table top halves 120 and 121, which is the smallest possible structural storage profile that can be achieved for a two piece collapsible table let alone the 5 combined table and chair apparatus that forms the basis of the present invention.
In the alternate version ofthe prerel,ed embodiment depicted in FIGS. 13 and 14, a structural difference involves an auxiliary leg assembly 150 comprising a pair of relatively short auxiliary leg members 151 and 152 wherein the auxiliary leg members 151,152 ate pivotally connected to one another on their lower ends; and, pivotally connected on their upper ends relatively to the pairs of support legs 132 and 133 proximate the pivoted connection of the seat support arms 141 with the support legs 132,133.
It should also be noted that each of the auxiliary leg members 151 and 152 comprise a pair of contoured leg elements wherein the pair of leg elements of auxiliary 15 leg members 151 are dimensioned to be received within the pair of leg elements of auxiliary leg member 152.
It should further be noted that the pl erel l ed embodiment of the invention depicted in FIGS. 8 thru 12 is designed for use with children; whereas, the alternate version depicted in FIGS. 6 and 7 is designed for adults and requires the presence of the 20 auxiliary leg assembly. Furthermore, as shown in the dashed line portion of FIG. 3, this invention also contemplates the provision of stepped shoulders 138 on each pair of support legs 132,133 such that the stepped shoulders 138 may serve as a foot rest for the users.
