     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now in detail to the drawings for the purpose of illustrating preferred embodiments of the present invention, a combined table and seat assembly 10 as shown in FIGS. 1 and 2 comprises a table 11 having two identical table top halves 11a and 11b which are pivotally connected to one another at their abutting side edges by way of a pair of hinge plates 13a and 13b, and seat assemblies 12 including a pair of seats 12a and 12b, respectively. The seat assemblies 12 are connected to the table halves 11a and 11b by table support members 14a and 14b and extending table support members 17a and 17b, and by a pair of auxiliary table support members 15a and 15b, respectively. The pair of auxiliary table support members 15a and 15b are connected with the extending table support members 17a and 17b by pivot pins 24, respectively. 
     Each of table top halves 11a and 11b includes downwardly extending peripheral walls 16a and 16b, which define hollow regions underneath each of the table top halves 11a and 11b, respectively. The hollow regions acting as containers for the seat assemblies 12 when these seat assemblies 12 are collapsed as will be described in more detail hereinafter. The table 11 is made of plastic, fiberglass, or the like. 
     As shown in FIGS. 3-7, the seat assemblies 12 include legs 18, a pair of seat support members 19a and 19b, inside and outside frames 20a and 20a&#39;, 20b and 20b&#39;, and the pair of seats 12a and 12b disposed in the seat assemblies 12, respectively. First connecting members 21a and 21b pivotally extend to second connecting members 22a and 22b by pivot pins 24 for connecting between the inside frames 20a and 20b, and the first table support members 14a and 14b. The first and second connecting members 21a, 21b, 22a and 22b are pivotally secured to the first table support members 14a and 14b and to joint members 25a and 25b by pivot pins 24, which are mounted to the inside frames 20a and 20b of the seat assemblies 12. Bent bars 23a and 23b are attached to the first connecting members 21a and 21b, respectively. The second connecting members 22a and 22b include slots 27a and 27b for operatively engaging one end of the bent bars 21a and 21b, respectively, to protect the second connecting members 22a and 22b from bending about the bent bars 23a and 23b, respectively (FIG. 7). Also, the first table support members 14a and 14b can be arranged in parallel with the second table support members 15a and 15b, respectively, when the seat assemblies 12 are collapsed into a carrying case composed of the table top halves 11a and 11b. The pair of second table support members 15a and 15b are pivotally secured to the inside frames 20a and 20b of the seat assemblies 12 by pivot pins 24 through joint members 25a and 25b, respectively (FIG. 6). 
     As shown in FIGS. 8-12, the pair of seat support members 19a and 19b are composed of channels 26a and 26b disposed at tip portions of lower arms 28a and 28b on three sides, and tubular upper arms 29a and 29b connected with the channels 26a and 26b by pivot pins 24, respectively. The other two sides of the lower arms 28a and 28b are connected to the pair of legs 18 of the seat assemblies 12 by pivot pins 24 through joint members 25a and 25b, respectively (FIG. 8). The channels 26a and 26b include, fixing pins 30a and 30b having chains 31 and 30b, respectively, for mounting the fixed pins thereto (FIG. 10). Also, the channels 26a and 26b further include engaging members 32a and 32b for engaging the fixing pins 30a and 30b therein, and apertures 33a and 33b for fixing the fixing pins 30a and 30b  therein, respectively, when the seat assemblies 12 are fully opened from the folding table and seat assembly 10 (FIG. 9). Also, the tubular upper arms 29a and 29b contain tensible ring members 34a and 34b having a pair of projecting members 35a and 35b which may have an elliptical configuration, respectively. Therefore, when the folding table and seat assembly 10 are opened, the seat assemblies are effectively stabilized since the fixing pins 30a and 30b are engaged in the apertures 33a and 33b as well as the pair of projecting members 35a and 35b of the ring member 34a and 34b are tightly engaged in the apertures 33a and 33b due to tensibility, for protecting the tubular upper arms 29a from bending toward the channels 26a and 26b, respectively. Also, when the seat assemblies 12 are collapsed into the self-contained carrying case, the fixing pins 30a and 30b are removed from the apertures 33a and 33b of the channels 26a and 26b of the lower arms of 38a and 28b, respectively. 
     As shown in FIGS. 13 and 14, the pair of hinge plates 13a and 13b include a plurality of bolts 36 for mounting the hinge plates to edge portions of the walls 16a and 16b, respectively, and pivot pins 24 for pivotally engaging the hinge plates 13a together at the corners thereof, respectively, (FIG. 14). 
     Referring in detail to FIGS. 15 and 18, there is illustrated an additional embodiment of a hinge plate in accordance with the present invention. Hook members 37 are pivotally attached to the bolt 36 for locking the other bolt 36 (FIG. 16). The hinge plates 13a and 13b include a plurality of grooves 38 disposed in the lower edges thereof for functioning as a foot pad. 
     As shown in FIGS. 2, 17 and 18, the folding table and seat assembly 19 is provided with a handle 39 composing handle halves 39a and 39b and locking members 40. The locking member 40 has hollow portions 41 and a plurality of protrusions 42 for operatively engaging a plurality of vertical grooves 43 disposed in the surface of one handle half 39a with grooves 43 disposed in the surface of the other handle half 39b, wherein the seat half 39b includes a rectangular groove 44 for releasing the locking member 40 from the seat half 39b when the assembly 10 is opened (FIG. 18). 
     The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included in the scope of the following claims.
