DETAILED DESCRIPTION OF THE EMBODIMENTS

(6) Referring to FIGS. 1-5, there is shown a water proof sleeve 10 for an electronic device 12. The water proof sleeve 10 includes an elastic body 14 including an open top 16 and a curved side wall 18 joined to a bottom wall 20. The curved side wall 18 and bottom wall 20 define an internal cavity 22 receiving the electronic device 12. In one aspect, the elastic body 14 may be formed of a high tensile strength silicone material. The high tensile strength silicone retains its elastic property and applies a biasing force to a water sealing rib 24 to maintain a seal with the electronic device 12 as will be discussed in more detail below.

(7) The side wall 18 includes separated inner and outer surfaces 26, 28. The inner surface 26 includes a plurality of separated sealing ribs 30 formed thereon. The plurality of sealing ribs 30 is formed circumferentially about the side wall 18 and extends radially inward toward the electronic device 12. One of the plurality of ribs 30 is a water sealing rib 24 and includes a radial dimension that is greater than in comparison to the other sealing ribs 32 of the plurality of sealing ribs 30. In one aspect, the water sealing rib 24 includes a radial dimension that is at least twice the size in comparison to the other sealing ribs 32 of the plurality of sealing ribs 30.

(8) The side wall 18 includes a fold partition 34 formed therein. The fold partition 34 includes a trough 36 formed therein that extends from the inner surface 26 toward the outer surface 28. The trough 36 defines a fold line 38 which allows the sleeve 10 to be moved between open and closed positions as will be discussed in more detail below.

(9) In the depicted embodiments, the plurality of sealing ribs 30 are formed proximate the open top 16. In one aspect, the water sealing rib 24 is positioned closer to the open top 16 relative to the other of the plurality of ribs 30. The other of the plurality of ribs 30 may act as dust ribs 32 as will be discussed in more detail below.

(10) Referring to FIG. 5, the water sealing rib 24 includes a compound curve 40. The compounds curve 40 seals to a curved surface 42 of the electronic device 12.

(11) The compound curve 40 includes a first radius and a second radius 44, 46. The first radius 44 is larger than the second radius 46 and seals to the curved surface 42 of the electronic device 12. The first and second radii 44, 46 converge to a tip portion 48 to prevent ingress of water.

(12) In use, the electronic device 12 may be positioned through the open top 16 and then within the internal cavity 22 defined by the side wall 18 and bottom wall 20. The sleeve 10 may be moved between the open position shown in FIG. 1 (labeled as position 3) where a user may have access to the electronic device 12 and the closed position shown in FIG. 1 labeled as position 1. In the open position, the sleeve 10 is folded about the fold line 38 to allow access to the electronic device 12.

(13) In the closed position, the water sealing rib 24 flexes due to an elastic force applied by the silicone material of the sleeve 10. The flexed water sealing rib 24 includes the compound curve 40 which contacts the curved surface 42 of the electronic device 12 providing a robust water proof seal.

(14) The single water sealing rib 24 having a radial dimension at least twice that of the other ribs 32 provides an improved seal in comparison to a plurality of sealing ribs having the same radial dimension. The single water sealing rib 24 results in a focusing of the elastic force of the sleeve to a single rib as opposed to a distribution of the force over multiple ribs if all the sealing ribs were of the same size.
