Abstract

A wheeled cooler (10) is provided having an open top housing (22) with a removable cover member (24) forming a closed internal chamber (16) for the storage of articles. At least two wheel members (12) are rotatably secured to opposingly displaced sidewalls (32, 32'"'"') of the open top housing (22). The wheel members (12) have a mechanism for removably capturing each of the wheel members (12) individually within a respective transversely displaced sidewall (32, 32'"'"'). The wheel capturing mechanism (40) includes a wheel base member (42) which may be inserted in a tongue in groove connection to the sidewalls (32, 32'"'"'). In this manner there is provided a wheeled cooler (10) which may easily have the wheel members (12) removable from the housing (22) or inserted within the housing (22) for rotatable transport across a base surface (14).

Claims

1. A wheeled cooler comprising:

(a) an open top housing having a pair of opposing transversely displaced sidewalls and opposing longitudinally displaced frontal and rear walls, said open top housing defining an internal cooling chamber;

(b) a cover member releasably engageable to said open top housing;

(c) at least two wheel members rotatably secured to said opposing transversely displaced sidewalls of said open top housing;

(d) means for removably capturing each of said wheel members individually within a respective one of said opposing transversely displaced sidewalls, said means for removably capturing each of said wheel members including a wheel base member slidably insertable in a vertical direction within a pair of longitudinally displaced grooves formed in said sidewall of said housing and a wheel axle extending substantially normal said wheel base member, each of said wheel members being rotatably coupled to a respective wheel base member;

(e) means for vertically capturing each of said wheel base members to a respective one of said sidewalls within said longitudinally displaced grooves, including a respective wheel base pin member insertable through a respective wheel base through opening formed through a respective wheel base member, said wheel base through opening alignable with a housing sidewall recess for insert of said wheel base pin therein; and

,

(f) means for releasably securing said wheel base pin member to said wheel base member and said housing sidewall including spring biasing means mounted to said wheel base member and contiguous said base pin member for applying a force loading to said base pin member to maintain said base pin member within said sidewall recess.

2. The wheeled cooler as recited in claim 1 where said wheel base member and said sidewall of said housing are releasably coupled through a tongue in groove securement.

3. The wheeled cooler as recited in claim 1 where said wheel base member is wedge shaped in cross-sectional contour for sliding insert into said grooves in said substantially vertical direction.

4. The wheeled cooler as recited in claim 1 where said spring biasing means includes a leaf spring member secured to said wheel base member and selectively positionable over said wheel base member through opening.

5. The wheeled cooler as recited in claim 1 including means for removably securing each of said wheel members to a respective wheel axle on one end of each of said wheel axles.

6. The wheeled cooler as recited in claim 5 where said means for removably securing each of said wheel members includes:

(a) a threaded bolt member for threaded engagement with a threaded opening formed within said end of said wheel axle; and

,

(b) a washer member having a central hole for insert therethrough of a stem of said threaded bolt member, said washer member having a diameter greater than a diameter of said wheel axle.

7. The wheeled cooler as recited in claim 1 including means for releasably securing said cover member to said open top housing.

8. The wheeled cooler as recited in claim 7 where said means for releasably securing said cover member includes:

(a) a pair of hook members secured to an external surface of said opposing housing sidewalls; and

,

(b) a flexible cord member having opposing loop contoured ends, said opposing loop contoured ends being insertable on respective hook members.

9. The wheeled cooler as recited in claim 8 where said flexible cord member is a resilient cord.

10. The wheeled cooler as recited in claim 1 including a pocket member secured to at least one of said sidewalls of said open top housing.

11. The wheeled cooler as recited in claim 10 where said pocket member is formed as a mesh pocket member releasably secured to at least one of said sidewalls of said open top housing.

12. The wheeled cooler as recited in claim 1 including removable handle means securable to said housing frontal wall for permitting pulling of said wheeled cooler on a base surface.

13. The wheeled cooler as recited in claim 12 where said handle means includes:

(a) a flexible strap member having opposing ends;

(b) a pair of closeable clip members secured respectively to said opposing ends of said flexible strap member; and

,

(c) a pair of frontal hook members mounted to said wheeled cooler frontal wall for engagement with said closeable clip members.
