Portable cooler
View Patent ↗A portable cooler includes a first semicylindrical member defining a first aperture in a first side and a second aperture in a second side thereof. A second semicylindrical member is hingedly coupled with the first semicylindrical member. A cradle is removably positioned in the first semicylindrical member. The cradle can rotate with respect to the first semicylindrical member within the space defined by the first semicylindrical member. First and second wheels are rotatably coupled with the first semicylindrical member. First and second axles extend through the wheels and first semicylindrical member and into the cradle. The axles allow independent rotation of the cradle, the first semicylindrical member and the wheels to maintain a substantially horizontal rotational orientation of the cradle with respect to the first semicylindrical member.
1. A portable cooler, comprising:
a first member defining a first side and a second side, the first member defining a first aperture in the first side and a second aperture in the second side of the first member, the first member defining a space therein;
a second member pivotably coupled with the first member;
a cradle positioned in the first member, the cradle defining a first side and a second side, the cradle defining a first orifice in the first side of the cradle and a second orifice in the second side of the cradle, wherein the cradle is configured to rotate with respect to the first member within the space defined by the first member;
a first wheel rotatably coupled with the first member at the first side of the first member;
a second wheel rotatably coupled with the first member at the second side of the first member;
a first axle extending through the first aperture in the first side of the first member and into the first orifice in the first side of the cradle; and
a second axle extending through second aperture in the second side of the first member and into the second orifice in the second side of the cradle.
2. The portable cooler of claim 1 , wherein the first and second members define a cylindrical member configured to rotate about the first axle and the second axle.
3. The portable cooler of claim 2 , further including:
a threaded bore formed in each of the first aperture in the first side of the first member and the second aperture in the second side of the first member;
a threaded member defined along each of the first axle and the second axle;
a first unthreaded member defined along each of the first axle and the second axle; and
a second unthreaded member defined along each of the first axle and the second axle,
wherein the threaded member of the first axle or the second axle is threaded into the threaded bore to connect the first axle or the second axle with the first member,
wherein the first unthreaded member is position in the first wheel or the second wheel, the first unthreaded member configured to allow rotation of the first wheel or the second wheel with respect to the first member, and
wherein the second unthreaded member is positioned in the first orifice or the second orifice of the cradle, the second unthreaded member configured to allow rotation of the cradle with respect to the first member.
4. The portable cooler of claim 3 , wherein the first axle and the second axle are removably coupled with the first member.
5. The portable cooler of claim 1 , further including a handle coupled with the first wheel and the second wheel, wherein the first wheel is configured to rotate about the first axle independently of the handle, and the second wheel is configured to rotate about the second axle independently of the handle.
6. The portable cooler of claim 1 , wherein the first member is larger than the second member.
7. The portable cooler of claim 6 , further including a central axis defined through the first member, wherein the first axle and the second axle each extend along the central axis.
8. The portable cooler of claim 1 , further including a hinge connecting the first member with the second member.
9. The portable cooler of claim 8 , wherein the hinge is a piano hinge or a concealed hinge.
10. The portable cooler of claim 1 , further including a sidewall defined in at least one of the first member or the second member, and insulation arranged within the sidewall.
11. The portable cooler or claim 1 , further including at least one handle arranged about the cradle.
12. The portable cooler of claim 1 , further including an inner sidewall defined in the cradle, and at least one indent formed in the inner sidewall of the cradle, the at least one indent configured for lifting the cradle out of the first member.
13. The portable cooler of claim 1 , further including at least one latch coupled with the first member or the second member, the at least one latch configured to secure the first member to the second member.
14. The portable cooler of claim 1 , further including a second space defined in the second member.
15. The portable cooler of claim 1 , further including a second handle removably coupled with the handle.
16. The portable cooler of claim 1 , further including at least one cushioned member connected with the handle or the second handle.
17. The portable cooler of claim 1 , further including an indent formed in the first member and a protrusion formed in the second member, the indent configured to receive the protrusion therein to form a seal between the first member and the second member.
18. The portable cooler of claim 17 , further including a sealing member extending along the first member or the second member.
