Rail skirt system

1. A rail skirt system for a collapsible shelter having a plurality of legs, comprising:

a top rail removably connected between an adjacent pair of said plurality of legs, wherein said top rail includes a middle connector tube, and first and second rail bar members having inner ends that are removably received in the middle connector tube, each said rail bar member including an outer locking end with a pair of spring mounted outer detent pins extending from opposing sides of the outer locking end of the rail bar member, wherein said locking ends of the rail bar members are connected between adjacent legs of the shelter with fixed corner connecting brackets, each of said fixed corner connecting brackets having a pair of journal arms pivotally connected together by a pivot pin, and having an open configuration and a closed configuration that clamps to one of said plurality of legs of the shelter, and wherein said journal arms have outer ends that are forked and that include apertures that receive the outer detent pins of the outer locking ends of the rail bar members, allowing the rail bar members of the top rail to be clamped to the legs of the shelter; and

a skirt removably attached to and depending from said top rail.

2. The rail skirt system of claim 1 , wherein said detent pins are mounted on opposing leaf springs secured inside the outer locking end of the rail bar member.

3. The rail skirt system of claim 2 , further comprising a pair of inner buttons mounted on said opposing leaf springs, such that pressing one of the inner buttons depresses the corresponding outer detent pin of the corresponding leaf spring.

4. The rail skirt system of claim 1 , wherein said middle connector tube comprises a middle forked bracket.

5. The rail skirt system of claim 4 , further comprising a locking support leg having a bottom end and an opposing locking end with a pair of spring mounted outer detent pins extending from opposing sides of the locking end and connectable with said middle forked bracket, said outer detent pins being mounted on opposing leaf springs secured inside the locking end of the locking support leg.

6. The rail skirt system of claim 5 , further comprising a pair of inner buttons mounted on said opposing leaf springs of said locking support leg, such that pressing one of the inner buttons depresses the corresponding outer detent pin of the corresponding leaf spring, allowing the locking support leg to connect the opposing outer detent pins in apertures of the middle forked bracket of the middle connector tube of the top rail.

7. The rail skirt system of claim 1 , wherein said rail skirt is double sided.

8. A collapsible shelter, comprising:

a canopy portion with at least three sides and at least three corners;

a plurality of legs at said corners of said canopy portion to support the canopy portion;

a collapsible framework connected between adjacent pairs of said plurality of legs to stabilize and support the collapsible shelter;

a rail skirt removably connected between adjacent pairs of said plurality of legs of the collapsible shelter along at least one side of the collapsible shelter;

a top rail removably connected between an adjacent pair of said plurality of legs, said top rail including a middle connector tube, and first and second rail bar members having inner ends that are removably received in the middle connector tube, each said rail bar member including an outer locking end with a pair of spring mounted outer detent pins extending from opposing sides of the outer locking end of the rail bar member, wherein said locking ends of the rail bar members are connected between adjacent legs of the shelter with fixed corner connecting brackets, each of said fixed corner connecting brackets having a pair of journal arms pivotally connected together by a pivot pin, and having an open configuration and a closed configuration that clamps to one of said plurality of legs of the shelter, and wherein said journal arms have outer ends that are forked and that include apertures that receive the outer detent pins of the outer locking ends of the rail bar members, allowing the rail bar members of the top rail to be clamped to the legs of the shelter; and

said rail skirt removably attached to and depending from said top rail.

9. The rail skirt system of claim 8 , wherein said detent pins are mounted on opposing leaf springs secured inside the outer locking end of the rail bar member.

10. The rail skirt system of claim 9 , further comprising a pair of inner buttons mounted on said opposing leaf springs, such that pressing one of the inner buttons depresses the corresponding outer detent pin of the corresponding leaf spring.

11. The rail skirt system of claim 8 , wherein said middle connector tube comprises a middle forked bracket.

12. The rail skirt system of claim 11 , further comprising a locking support leg having a bottom end and an opposing locking end with a pair of spring mounted outer detent pins extending from opposing sides of the locking end and connectable with said middle forked bracket, said outer detent pins being mounted on opposing leaf springs secured inside the locking end of the locking support leg.

13. The rail skirt system of claim 12 , further comprising a pair of inner buttons mounted on said opposing leaf springs of said locking support leg, such that pressing one of the inner buttons depresses the corresponding outer detent pin of the corresponding leaf spring, allowing the locking support leg to connect the opposing outer detent pins in apertures of the middle forked bracket of the middle connector tube of the top rail.

14. The rail skirt system of claim 8 , wherein said rail skirt is double sided.
