Securing apparatus for cover

1. A cover having a top portion and a first lateral side portion adjacent a second lateral side portion adjacent a third lateral side portion adjacent a fourth lateral side portion, the first, second, third, and fourth lateral side portions extending from the top portion, and a first securing system, the first securing system comprising:

a securing device extending along at least a portion of a perimeter of the cover, the perimeter circumscribing the first, second, third, and fourth lateral side portions;

a retaining device to couple the securing device to the cover; and

a locking device, wherein the securing device, locking device, and combinations thereof are configured to dynamically change a length of the perimeter of the cover,

wherein the securing device comprises two or more cords and the retaining device comprises a channel formed in the cover through which the securing device is threaded, and

wherein a first cord is attached to the cover at a first attachment point on the cover such that relative motion between the first cord and the first attachment point is limited and a second cord is attached to the cover at a second attachment point on the cover such that relative motion between the second cord and the second attachment point is limited, and the locking device couples the first cord to the second cord.

2. The cover of claim 1 , wherein a combination of the securing device and locking device fully circumscribe the perimeter.

3. The cover of claim 1 , wherein the securing device comprises three cords and the locking device comprises three locking apparatus, one of the three locking apparatus positioned and coupling adjacent two of the three cords, the retaining device comprising three openings to permit access to the three locking apparatus.

4. The cover of claim 1 , wherein the first attachment point is on one lateral side of the cover and the second attachment point is on an adjacent lateral side of the cover.

5. The cover of claim 4 , wherein the first attachment point couples a terminal end of the first cord to the cover and the second attachment point couples a second terminal end of the second cord to the cover.

6. The cover of claim 1 , wherein the locking device is positioned between one or more sections of the securing device.

7. The cover of claim 1 , wherein the securing device comprises four pairs of cords, wherein each pair of cords has a terminal end of one of the pair of cords coupled to one of a lateral side of the cover and the other of the pair of cords has a terminal end coupled to an adjacent one of a lateral side of the cover, wherein the locking device comprises four locking devices positioned between and coupling each pair of cords.

8. The cover of claim 7 , wherein the locking device comprises a buckle or cord lock.

9. The cover of claim 7 , wherein each pairs of cords is separated along the perimeter from an adjacent pair of cords such that portions of the perimeter are not enclosed by the securing device.

10. A cover having a top portion and a first lateral side portion adjacent a second lateral side portion adjacent a third lateral side portion adjacent a fourth lateral side portion, the first, second, third, and fourth lateral side portions extending from the top portion, and a first securing system and a second securing system,

the first securing system comprising:

at least two first cords fully circumscribing and extending along a first perimeter of the cover, the first perimeter circumscribing the first, second, third, and fourth lateral side portions, and

a first retaining device to couple the at least two first cords to the cover, and

a first locking device coupling the at least two first cords to each other, wherein the at least two first cords, the first locking device, and combinations thereof are configured to dynamically change a length of the first perimeter of the cover; and

the second securing system comprising:

at least two pairs of second cords extending along a second perimeter of the cover, the at least two pairs of second cords extending along only a portion of the second perimeter such that a gap is formed between the two pairs of second cords, the second perimeter circumscribing the first, second, third, and fourth lateral side portions, and

a second retaining device to couple the at least pairs of second cords to the cover, and

at least two second locking devices, each second locking devices coupling individual cords of the pairs of second cords to each other, wherein the pairs of second cords, the second locking device, and combinations thereof are configured to dynamically change a length of the second perimeter of the cover.

11. The cover of claim 10 , wherein the first and second retaining devices are channels formed in the cover.

12. The cover of claim 10 , wherein the first securing system circumscribes a lower portion of the cover and the second securing system partially circumscribes an upper portion of the cover.

13. The cover of claim 10 , wherein each of the at least two first cords and each of the at least two pairs of second cords are directly coupled to the cover separate from the first and second retaining device.
