연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A cooler comprises a main body which includes a base, an upper rim, and one or more cooler walls extending therebetween. The cooler further comprises a removable wheel assembly which includes two coaxial wheels, and an axle. The two coaxial wheels are removably securable to the axle. The cooler still further comprises a wheel fastening system configured to secure the removable wheel assembly to the base of the main body which includes a mount, a clip hingedly connected to the mount, and a locking clasp configured to lock the clip into a closed position to secure the wheel assembly. The cooler yet further comprises a lid including two wheel storage recesses, each being sized and dimensioned to receive and retain one of the coaxial wheel of the wheel assembly, and an axle storage recess sized and dimensioned to receive and retain the axle of the wheel assembly.

1. A cooler, comprising: (a) a main body including, (i) a base having a footing for support of the cooler around a periphery of the base when the cooler is placed on a flat support surface,(ii) an upper rim, and(iii) one or more cooler walls extending between the upper rim and the base;(b) a removable wheel assembly including an axle and two wheels removably securable to the axle in coaxial position relative to one another, the main body of the cooler defining a recess (i) extending between front and back sides of the cooler proximate an end of the cooler, and(ii) sized and dimensioned to removably receive the axle therein such that the cooler is able to be rolled on the wheels when the two wheels are positioned in coaxial relation to one another on the axle and the axle is received within the recess; and(c) a wheel fastening system configured to secure the axle of the removable wheel assembly within the recess of the main body;(d) wherein, when the wheel assembly has been removed from the base, the wheel fastening system does not extend below the footing of the base so as to interfere with the support provided by the footing around the periphery of the base when the cooler is placed on a flat support surface;(e) wherein the one or more cooler walls extending between said base and said upper rim each comprise a tapered, flexible membrane formed of silicone rubber and including a plurality of hinge lines having less thickness than portions of the membrane extending between the hinge lines, the membrane being configured to bend at each hinge line for collapsing of the cooler. 2. The cooler of claim 1, wherein the cooler further includes a handle. 3. The cooler of claim 2, wherein the handle is removably attachable to the base. 4. The cooler of claim 3, wherein the cooler includes a lid having a handle storage recess for storage of the handle. 5. The cooler of claim 2, wherein the handle is telescoping. 6. The cooler of claim 2, wherein the handle is telescoping and removably attachable to the base. 7. The cooler of claim 1, further comprising a lid including (i) two wheel storage recesses, each being sized and dimensioned to receive and retain one of the wheels of the wheel assembly, and (ii) an axle storage recess separate from the two wheel storage recesses and sized and dimensioned to receive and retain the axle of the wheel assembly. 8. The cooler of claim 7, wherein the main body includes a front side and a back side separated by a width of the cooler, and opposite ends separated by a length of the cooler, the length being greater than the width, and wherein the axle has a length sufficient to extend the width of the cooler. 9. The cooler of claim 1, wherein the wheel fastening system comprises, (a) a mount located on a bottom of the cooler such that the recess is located between the mount and the end of the cooler to which the recess is proximate,(b) a clip hingedly connected to the mount and movable between (i) an open position in which the axle is insertable into and removable from the recess, and (ii) a closed position in which the clip extends over the axle and precludes insertion into and removal of the axle from the recess when the axle is received within the recess, and(c) a locking clasp located proximate the base at the end of the cooler to which the recess is proximate, the locking clasp configured to lock the clip in the closed position to secure the wheel assembly, the locking clasp extending along a side surface of the base when the locking clasp locks the clip into the closed position. 10. The cooler of claim 1, wherein the cooler further includes a handle that is hingedly connected to the base for pivoting movement relative to the base. 11. The cooler of claim 1, wherein at least one of the one or more cooler walls tapers inwardly in extending from the upper rim, and tapers inwardly in extending from the base, such that a middle section of the at least one of the one or more cooler walls has a cross-sectional perimeter that is less than a cross-sectional perimeter of the at least one of the one or more cooler walls at the base or upper rim. 12. A method of transitioning a cooler from a first configuration, in which the cooler is able to be rolled on wheels, to a second configuration, in which the cooler is not able to be rolled on wheels, comprising the steps of: (1) providing a cooler, comprising, (a) a main body comprising, (i) a base having a footing for support of the cooler around a periphery of the base when the cooler is placed on a flat support surface,(ii) an upper rim, and(iii) one or more cooler walls extending between the upper rim and the base,(b) a removable wheel assembly including an axle and two wheels removably secured to the axle in coaxial position relative to one another, the main body of the cooler defining a recess extending between front and back sides of the cooler proximate an end of the cooler, in which recess the axle is received such that the cooler is able to be rolled on the wheels, and(c) a wheel fastening system configured to secure the axle of the removable wheel assembly within the recess of the main body during rolling of the cooler,(d) wherein the one or more cooler walls extending between said base and said upper rim each comprise a tapered, flexible membrane formed of silicone rubber and including a plurality of hinge lines having less thickness than portions of the membrane extending between the hinge lines, the membrane being configured to bend at each hinge line for collapsing of the cooler,(2) removing the wheel assembly from the recess defined in the main body; and (3) configuring the wheel fastening system such that the wheel fastening system does not extend below the footing of the base so as to interfere with the support provided by the footing around the periphery of the base when the cooler is placed on a flat support surface. 13. The method of claim 12, further comprising removing the wheels from the axle and storing the wheels and the axle within recesses defined in the lid of the cooler. 14. The cooler of claim 12, wherein the cooler further includes a handle attached to the base.
