DESCRIPTION OF THE.DRAWINGS
-The embodiment shown in the drawings consists of a stadium building 10 having a roof or dome 1?. resting on a wall structure 14. Wall structure 14 comprises a pair of parallel, opposed side walls 18 and 20 together with end walls 22 and 24. roof 12 comprises a central arch having a pair of parallel barrel vaults 26 and 28 movably mounted on side walls 18 and a pair of opposed angular end segments 30 and 32. End segment 30 is fixed on end wall 22 and end segment 32 is mounted on end wall 24 which is arcuate in a horizontal plane. Side wall 20 includes a lateral arcuate base 34 which forms with arcuate end wall 24 a semi-circular support means or base on which end segment 32 is movably mounted.
Each end barrel vault 26 is carried on a row of trucks (not 13306~4 shown) which travel along a set of tracks 36 fixed on opposed side walls 18. Each end of barrel vault 28 is carried on a row oE trucks (not shown) which travel along a set of tracks 38 also fixed on opposed side walls 18. End segment 32 is carried on a row of trucks (not shown) which travel on a set of tracks 40 on end wall 24 and portion 3~ of side wall 18. The manner of mounting barrel vaults 26, 28 and end segment 32 on their respective tracks is fully described in our aforementioned United States Patent No. 4,676,033 the contents of which are specifically incorporated herein by reference.
In construction and operation, stadium 109 may be built around an existing covered stadium 50 which is indicated in the drawings in chain-dotted outline. As seen in Figures 1 and 3 and in broken lines in Figures 5 and 6, roof 12, when open, has end segment 32 positioned on base 34 with its central horizontal axis at right angles to the central horizontal axis of the roof and being located laterally of tcacks 36 and 38. Also in the open mode of roof 12, barrel vaults 28 and 28 are telescoped into a nesting position above fixed end segment 30 and end wall 22 extend rearwardly to, accommodate tracks 36 and 38, as seen most clearly in Figure 4.
To close roof 12, end segment 32 is moved along track 40 onto end wall 24 to have its central longitudinal axis coincide with that of the roof as a whole. Barrel vauit 26 is moved along track 36 in the direction of end segment 32 and barrel vault 28 is moved along track 38 to abut end segment 32 as seen in Figures 2, 4 and 6. Suitable sealing means 52, for example downwardly extending fl~nges cooperating with r ~ealing element, ~ompletes the clo~ure.
,~
. , \
133~614 The construction of stadium 10 may be carried out while existing covered stadium 50 continues to be used. In such construction portions of barrel vaults 26 and 28 are assembled and erected over base 2~ which is constructed to one side of existing stadium 50. As each portion of a barrel vault 26 or 28 is completed it is moved along side walls 18 and 20, also newly erected, over stadium 50, allowing space for the erection of the remaining portions of the same vault. In like mannee movable segment 32 is constructed over newly erected lateral base 34 associated with wall 20. In this manner there is no disruption of the normal activities of existing stadium 50. When stadium 10 is complete, roof 12 may be closed and used to assist in dismantling the roof of stadium 50.
In fact the structure of stadium 10 may be attached to the supporting structure of stadium 50 and, as seen in Figure 6, this would allow for the use of existing seating 54 and an extension 56 of that seating after the roof of stadium 50 has been removed.
It will be appreciated that the central arch, formed by barrel vaults 26, 28 in the described embodiment, may consist of one or more such vaults.
It will also be appreciated that fixed end segment 30 could be any shape, even a flat wall, to seal that end of roof 12 at end wall 22, and could include an overhang beneath the central arch.
Arcuate portion 34 of side wall 20 is shown as a solid cubic structure but any structure could be used which would support track 40, for example a colonnaded platform or deck.
In the first alternate embodiment shown in Figures 7, 8 and 9 of the drawings consists of the central arch comprises a 1 3 3 ~
first barrel vault 60 adjacent fixed end segment 30 and a second barrel vault 62 adjacent a movable end segment 64 which covers the opening at the end of vault 62. Since end segment 64 is smaller than movable end segment 32 in the previous embodiment, lateral base 34 is smaller in area. Figures 9A and 9B show two example arrangements of the elements of the roof structure to achieve this result.
In the second alternate embodiment of the invention shown in ~igures 10, 11 and 12 of the drawings the central arch comprises a single barrel vault 70 and a movable end segment 72 which is movable on an arcuate rail 74 fixed on a semicircular end wall 76 to which side wall 20 is tangent. To open the roof of this embodiment, barrel vault 70 is movable on rails 38 back over end wall 22 and end segment 32 is moved along track 72 to an open position at right angles to its closed position.
The advantage of the second alternate embodiment is economy of space and also of construction costs, as well as allowing for more seats. As in the previous embodiments the central arch may be a single vault or multiple vaults which telescope together. Also, fixed end segment 30 may be merely a wall

DESCRIPTION OF THE.DRAWINGS
-The embodiment shown in the drawings consists of a stadium building 10 having a roof or dome 1?. resting on a wall structure 14. Wall structure 14 comprises a pair of parallel, opposed side walls 18 and 20 together with end walls 22 and 24. roof 12 comprises a central arch having a pair of parallel barrel vaults 26 and 28 movably mounted on side walls 18 and a pair of opposed angular end segments 30 and 32. End segment 30 is fixed on end wall 22 and end segment 32 is mounted on end wall 24 which is arcuate in a horizontal plane. Side wall 20 includes a lateral arcuate base 34 which forms with arcuate end wall 24 a semi-circular support means or base on which end segment 32 is movably mounted.
Each end barrel vault 26 is carried on a row of trucks (not 13306~4 shown) which travel along a set of tracks 36 fixed on opposed side walls 18. Each end of barrel vault 28 is carried on a row oE trucks (not shown) which travel along a set of tracks 38 also fixed on opposed side walls 18. End segment 32 is carried on a row of trucks (not shown) which travel on a set of tracks 40 on end wall 24 and portion 3~ of side wall 18. The manner of mounting barrel vaults 26, 28 and end segment 32 on their respective tracks is fully described in our aforementioned United States Patent No. 4,676,033 the contents of which are specifically incorporated herein by reference.
In construction and operation, stadium 109 may be built around an existing covered stadium 50 which is indicated in the drawings in chain-dotted outline. As seen in Figures 1 and 3 and in broken lines in Figures 5 and 6, roof 12, when open, has end segment 32 positioned on base 34 with its central horizontal axis at right angles to the central horizontal axis of the roof and being located laterally of tcacks 36 and 38. Also in the open mode of roof 12, barrel vaults 28 and 28 are telescoped into a nesting position above fixed end segment 30 and end wall 22 extend rearwardly to, accommodate tracks 36 and 38, as seen most clearly in Figure 4.
To close roof 12, end segment 32 is moved along track 40 onto end wall 24 to have its central longitudinal axis coincide with that of the roof as a whole. Barrel vauit 26 is moved along track 36 in the direction of end segment 32 and barrel vault 28 is moved along track 38 to abut end segment 32 as seen in Figures 2, 4 and 6. Suitable sealing means 52, for example downwardly extending fl~nges cooperating with r ~ealing element, ~ompletes the clo~ure.

. , \
133~614 The construction of stadium 10 may be carried out while existing covered stadium 50 continues to be used. In such construction portions of barrel vaults 26 and 28 are assembled and erected over base 2~ which is constructed to one side of existing stadium 50. As each portion of a barrel vault 26 or 28 is completed it is moved along side walls 18 and 20, also newly erected, over stadium 50, allowing space for the erection of the remaining portions of the same vault. In like mannee movable segment 32 is constructed over newly erected lateral base 34 associated with wall 20. In this manner there is no disruption of the normal activities of existing stadium 50. When stadium 10 is complete, roof 12 may be closed and used to assist in dismantling the roof of stadium 50.
In fact the structure of stadium 10 may be attached to the supporting structure of stadium 50 and, as seen in Figure 6, this would allow for the use of existing seating 54 and an extension 56 of that seating after the roof of stadium 50 has been removed.
It will be appreciated that the central arch, formed by barrel vaults 26, 28 in the described embodiment, may consist of one or more such vaults.
It will also be appreciated that fixed end segment 30 could be any shape, even a flat wall, to seal that end of roof 12 at end wall 22, and could include an overhang beneath the central arch.
Arcuate portion 34 of side wall 20 is shown as a solid cubic structure but any structure could be used which would support track 40, for example a colonnaded platform or deck.
In the first alternate embodiment shown in Figures 7, 8 and 9 of the drawings consists of the central arch comprises a 1 3 3 ~
first barrel vault 60 adjacent fixed end segment 30 and a second barrel vault 62 adjacent a movable end segment 64 which covers the opening at the end of vault 62. Since end segment 64 is smaller than movable end segment 32 in the previous embodiment, lateral base 34 is smaller in area. Figures 9A and 9B show two example arrangements of the elements of the roof structure to achieve this result.
In the second alternate embodiment of the invention shown in ~igures 10, 11 and 12 of the drawings the central arch comprises a single barrel vault 70 and a movable end segment 72 which is movable on an arcuate rail 74 fixed on a semicircular end wall 76 to which side wall 20 is tangent. To open the roof of this embodiment, barrel vault 70 is movable on rails 38 back over end wall 22 and end segment 32 is moved along track 72 to an open position at right angles to its closed position.
The advantage of the second alternate embodiment is economy of space and also of construction costs, as well as allowing for more seats. As in the previous embodiments the central arch may be a single vault or multiple vaults which telescope together. Also, fixed end segment 30 may be merely a wall
