 2. Background of the Invention In my US. Pat. No. 3,699,986, there is disclosed an open-type tent pavilionand a number of module-type units that can be attached to the pavilion to form composite tents of various sizes and configurations. The pavilion disclosed therein utilizes resilient members to maintain a canopy and attached panels or walls offlexible sheet material taut&#39;v and the module-type units are adapted to be added onto the pavilion as extensions thereof or as separate closures for the pavilion openings.  
  The pavilion disclosed in my aforementioned patent has proven very satisfactory. However, in some instances. it is desirable that additional central head room he provided and particularly where the tentage is subjected to possibly heavy snow accumulations it is frequently desirable that a pitched roof that will allow the snow to more easily slide off, be used.  
 SUMMARY OF THE INVENTION structures in a unique manner such that the resulting structure, in its erected condition, has a plurality of identically arranged openings to which a base unit or other modular units can be attached in converting the open-type pavilion to an enclosed tent.  
  Another object is to provide an open-type pavilion, Constructed such that different base units can be easily attached thereto to change the over-all interior floor dimensions ofthe resulting tent, whereby a single pavilion can be converted into tents of varying sizes.  
  Still another object is to provide a tent pavilion with a pitched roof.  
  Principal features of the invention include a pavilion having a pair ofspaced end walls, supported by central and outer upright supports fanned out from anchor points for the end walls, a pitched roof extending between the end walls and side walls extending downwardly from the pitched roof to anchor points.  
  Additional objects and features of the invention will become apparent from the following detailed description and drawings disclosing what are presently contemplated as being the best modes of the invention.

 DETAILED DESCRIPTION Referring now to the drawings:  
  In the illustrated preferred embodiment, the structure of the invention includes a tent pavilion, shown generally at and a base unit, shown generally at 11.  
  The tent pavilion 10 includes a pair of end walls 13 and 14, a pair of side walls 15 and 16, and a roof 17 interconnecting the respective walls.  
  Each of the end walls has a pocket 18 formed at a lower end thereof, pockets 19 and 20 formed at the junctions of each end wall with the lower edges 17a of the roof, and a pocket 21 formed at the junction of the wall with the central ridge 17b of the roof. The edges of the end walls extend from the pockets 19 and 20 to the pocket 18 such that the portions of the end walls between the pockets l8, l9 and 20 are generally triangular in configuration.  
  The side walls 15 and 16 are also of generally triangular configuration, with their bases being connected to the lower edges 17a of the roof, and with the end walls extending downwardly and outwardly with respect to the roof of the erected pavilion, to apexes that serve as anchoring points for the the side walls. The usual tent peg loops 22 are provided at the apexes of the side walls so that stakes 23 can be driven therethrough to anchor the side walls to the ground. I &#39;u l As has been previously noted, the roof 17 has a central ridge 17b. Pockets 24 and 25 are formed at opposite ends of the ridge to receive the ends of a telescoping, locking, central ridge pole 26. During assembly of the pavilion, the opposite ends of pole 26 are respectively inserted into the pockets 24 and 25. The telescoping portions of pole 26 are extended to the maximum extent possible, thereby stretching the ridge 17b taut and the pole sections are locked together. Similarly, side roof poles 28 have their opposite ends inserted into pockets 29 and 30 provided therefore at opposite ends of the lower edges of the roof, adjacent to pockets 19 and 20. The side roof poles 28 are also made to telescope, with the telescoping sections arranged to be locked together at desired extension positions. During assembly of the pavilion, the side roof poles, like the center ridge pole, are inserted into the pockets provided therefore; are extended to stretch the rooffabric taut; and are then locked to hold them in the set extended positions. The central ridge pole and the side roof poles thus hold the roof taut between the end walls 13 and 14.  
  When the pavilion is assembled, the end walls are stretched into a taut, upright condition by an extended central, telescoping and locking upright pole 31 that has its opposite ends inserted into the pockets 18 and 21, and by extended outer telescoping and locking upright poles 32 and 33 that have their opposite ends inserted respectively into pockets 18 and 19, and 18 and 20.  
  For convenience of handling and to reduce the wear in pocket 18, the poles 31, 32 and 33 are all preferably pivotally connected by pins 34, as shown in FIG. 3, to a smoothly curved pivot plate 35 that is adapted to fit within the pocket 18. While they are not shown and, in  
 many instances they are not needed, it will be apparent that peg loops can be provided at pockets 18 to allow the pavilion to be further anchored in place. However, the downward pressure exerted through the poles 31, 32, and 33 will normally be sufficient to prevent movement of the pockets 18 and the end walls.  
  The poles 31, 32 and 33 stretch the end walls in away from pockets l8, and the anchored side walls stretch the roof taut between them and hold the poles 31, 32, and 33 taut in a fanned position, radiating like spokes from the pocket 18. So assembled, the pavilion is of pitched roof, open-type, with about one-half of the area beneath and around the roof enclosed by the side and end walls and with the spaces between wall edges being of generally triangular configuration.  
  The edges of the walls of the pavilion each have a zipper track, with the tracks of alternate edges having a zipper runner thereon. For purposes of clarity, those wall edges having a zipper track without a runner thereon will be identified with a while those having tracks with a;runner are identified with a The zipper tracks serve as part of a connection means for connecting the base unit 11 to the pavilion and additionally provide means for connecting units such as the modular tent unit 36, FIG. 6, having matching zipper portions surrounding the entrance way thereof, or such other modular units as are disclosed in my aforementioned US. Pat. No. 3,699,986, or of the type disclosed in my co-pending application for US. Pat. Ser. No. 295,516, filed Oct. 6, I972.  
  Because unit 11 comprises a floor 40, of generally rectangular configuration, and generally triangular walls 41, 42,,43,=and 44, each having its base connected to .one. side .of the floor. Floor 40 is dimensioned such that. the spread corners thereof and the base edges of the walls will fit within the ground engaging apexes of the pavilion walls, with the zipper tracks on the edges of the base-unit walls matching up with the zipper tracks on the edges of the pavilion walls. Alternate ones ofthe zipper tracks of the base unit do not have a zipper-runner thereon and these are identified, as before, with a The other zipper tracks of the base unit do have a zipper runner thereon and these are identified with a When the floor 40 is properly positioned within the base and the zipper tracks on the walls of the pavilion and base are matched up, the matched set of tracks include a runner to interlock the tracks or to release the tracks in customary zipper fashion.  
  A doorway having the usual bi-parting, zipper closed, tent screening 45 and cover flaps 46, both adapted to be tied back out of the doorway by ties 47, is provided through at least one wall of the base unit and a window opening, having a permanent screen covering 48 and back cover flaps 49, is preferably provided in at least one of the other base unitwalls.  
  In FIG. 4, there is shown another embodiment of base unit suitable for attachment to the pavilion unit of FIG. 1. In this embodiment, the base unit, shown generally at 50, includes a floor 51 of generally octagonal configuration. Four base unit walls 52, 53, 54 and 55 are fixed to the floor and each base unit wall is fixed to and projects from two adjacent edges of the floor to an apex. Zipper tracks and runners are provided on the I edges of the base unit walls, and if necessary, are continued along the base unit walls adjacent to the connection of the base unit walls with the floor, in thesame manner as has been previously disclosed.  
  Peg loops 56 are provided at the central intersections of each base unit wall and the adjacent edges of the floor. Thus, with the walls zipped into place in the pavilion openings the addition of four tent pegs 57 inserted through the stretched loops 56 will hold the base taut and provide an enlarged covered base area. Screened windows 58, with overlying fabric flaps can be provided in each of the walls, in which case access to the interior of the tent willbe by opening one of the zippers interconnecting the pavilion and base unit. Alternatively, a conventional bifold tent door 59, can be provided in one or more of the base unit walls.  
  Still another embodiment of base unit suitable for attachment to the pavilion unit of FIG. 1, is shown in FIG. 5. In this embodiment, the base unit, shown generally at 60, includes a generally rectangular floor 61 and base unit walls that each extend from a corner of the floor to a location generally between the mid-points of sides of the base, upwardly to a common apex.  
  Four tent peg loops 63 are provided, with one tent loop being connected to each corner of the floor, so that pegs 62 inserted therethrough will hold the floor and the floor unit walls attached thereto and connected to the pavilion walls in a tautly stretched condition.  
  As with the previously described embodiments, zipper tracks and runners are provided on the edges of the base unit walls and, if necessary, are continued along the base unit walls adjacent to the connection of the base unit walls with the floor so that the base unit walls can be connected to the pavilion walls. Screened windows 65 can be provided in the base unit walls and a conventional bi-parting tent door 64 can be provided in one or more of the base unit walls, should this be desired.  
 With the construction described, it is possible to&#39; greatly reduce the costs of producing and inventorying tents of various sizes. The pavilion portion of the tent can be of a standard size and bases of varying floor sizes can be adapted to be attached thereto. For example, with a standard pavilion having extended ridge poles 9 /2 feet long, extended side roof pole lengths and a distance between side roof poles of 6 /2 feet and a length of seven feet along each upright edge of the pavilion wall, a base unit of the type shown in FIG. 2 will provide a covered floor area of about eighty square feet. Using the same pavilion and a base unit of FIG. 4, a covered floor area of about I 10 square feet can be obtained, while if a base unit of the type shown in FIG. 5 is used, the covered floor area is about 144 square feet. It will be apparent that completely enclosed tents of varying sizes and shapes can thus be constructed, merely by providing base units of different floor areas and compatable base walls. This, of course, means that a manufacturer can build a single pavilion and a variety of base units, but that he does not need to build com plete tents of varying sizes in anticipation of sales that may or may not be realized. Similarly, dealers can maintain an inventory of tents of varying sizes, but in reality, need only an assortment of base units and some pavilion units since such base units can all adapt to use with the standard pavilion unit. The dealer can, therefore, maintain a variety of sizes of tents for sale, with a minimum of expenditure and storage space. The customer buying a tent of the present invention, can enlarge the tent size as his tentage requirements change, merely by acquiring a pavilion unit and then, as  
  needed, base units of selected floor area size or one or more modular tent units that can be connected to the pavilion walls to extend from the pavilion. If an even larger structure is desired. two or more pavilions can be interconnected at common openings.  
  lf desired, the pavilion, as herein disclosed, can be used with any of the base units disclosed, while at the same time one or more modular tent units can be attached to the pavilion. As shown in FIG. 6, for example. one base unit wall 44 is released from the adjacent pavilion walls. is rolled down to and under the base unit floor and the modular tent unit 36 is zippered into place.
