wherein said first and second link members are substantially parallel to each other and define a parallelogram structure in combination with said body portion and said thrust member such that movement of said thrust member toward said body portion causes said thrust member to move in a horizontal direction away from said respective first end.

2. The closure as recited in claim 1 wherein said first link member is located above said second link member, and a pivot connection between said second link member and said body portion is closer to said respective first end than a pivot connection between said first link member and said body portion.

3. The closure as recited in claim 1 wherein said horizontal members comprise telescoping tubes.

4. The closure as recited in claim 3 wherein said telescoping tubes are spring bias outwardly away from each other whereby said first and second ends of said horizontal members are bias toward said spaced sides of said area way.

5. The closure as recited in claim 1 wherein said body portion includes a shoulder area and each said vertical member includes opposing ends and a tube ring attached to each of said ends, each said tube ring including a circular portion positioned in engagement with a respective shoulder area.

6. The closure as recited in claim 5 wherein said circular portions of said tube rings on said first vertical member define a larger inner
circumference than an inner circumference of said circular portions of said tube rings on said second vertical member.

7. The closure as recited in claim 5 wherein said horizontal members are slidably received through said circular portions of said tube rings.

8. The closure as recited in claim 1 wherein said panel comprises a flexible fabric panel.

a locking structure attached to said first ends of said first and second horizontal members, said locking structure including an engagement portion for engaging a side of said area way and a parallelogram linkage supporting said engagement portion; and
wherein engaging said engagement portion and said second ends of said horizontal members with the sides of said area way causes said telescoping tubes to compress together to thereby provide a biasing force for maintaining said horizontal members in position within said area way.

11. The closure as recited in claim 10 wherein said locking structure comprises first and second lock assemblies attached to said first ends of said first and second horizontal members, respectively.

12. The closure as recited in claim 1 1 wherein each said lock assembly includes a body portion mounted to a respective first end, first and second link members pivotally mounted to said body portion and a thrust member located below said body portion and pivotally mounted to said first and second link members, said thrust member including an engagement surface defining said engagement portion for engaging a side of said area way.

13. The closure as recited in claim 12 wherein said first and second link members are substantially parallel to each other and define a
parallelogram structure in combination with said body portion and said thrust member such that movement of said thrust member toward said body portion causes said thrust member to move in a horizontal direction away from said respective first end.

14. The closure as recited in claim 13 including a spring acting on said thrust member to bias said thrust member away from said body portion.

15. The closure as recited in claim 10 wherein each said vertical member includes opposing ends and a tube ring attached to each of said ends, each said tube ring including a circular portion for receiving one of said horizontal members therethrough.

16. The closure as recited in claim 15 wherein said circular portions of said tube rings on said first vertical member define a larger inner
circumference than an inner circumference of said circular portions of said tube rings on said second vertical member.

17. The closure as recited in claim 10 wherein said panel comprises a flexible fabric panel.
