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, Kafe, Webinar 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.

The shopping cart has a foot pedal mechanism to adjust the height of the shopping basket to accommodate different sized users and can lower the cart height automatically with just the push of a button. The shopping basket includes separate detachable smaller bags used for bringing in items from the car. The cart is also designed to be fully collapsible to a height of only six inches and can be easily loaded into the rear trunk space of a car or SUV. The entire basket is also both collapsible and expandable in size and can also be detached from the cart e...

1. A collapsible shopping cart comprising: A) a frame which comprises a set of two upper longitudinal members that are parallel and are pivotally mounted to a separate basket carrier at their upper distal ends, and a set of shorter longitudinal lower members that are also parallel and are pivotally mounted to the upper members at their lower distal ends;B) a longitudinal cross support rod which is pivotally mounted at its left distal end to one set of upper and lower longitudinal frame members and at its right distal end to another set of upper and lower longitudinal frame members;C) a basket carrier platform that is pivotally mounted at its front distal end to both the upper longitudinal frame members at their upper distal ends and which further comprises a circular aperture at its geometric center as well as at least one pair of side circular apertures located approximately at the longitudinal midpoint and at the left and right sides of the platform and also a slotted rectangular aperture at its rear distal end;D) a handle which comprises a main handle grip, a set of side support members that are rigidly mounted to the grip and extend into the slotted aperture of said basket carrier, and a wireless two button radio frequency transmitter mounted internally into one of the side support members;E) a web basket which comprises a main web material on all four sides of the basket, a coiled spring that is assembled into the web fabric and which runs around all four sides of the basket, a base platform upon which the web basket is rigidly mounted to, and a set of rectangular shaped frame members that are rigidly attached to the web basket material with one frame member rigidly mounted at the top opening of the basket and the other frame member rigidly mounted at the bottom end of the web basket;F) two front wheels which are each pivotally mounted to a different one of the pair of shorter longitudinal lower frame members at their front distal ends;G) two rear wheels which are each pivotally mounted to a different one of the pair of shorter longitudinal lower frame members at their rear distal ends;H) an elevation mechanism which is mounted to one of the upper longitudinal frame members at its lower distal end and which comprises a ratchet gear, a pawl, a toothed drive gear, a power transmission belt, a wireless radio frequency receiver switch that is rigidly mounted to said pawl, and a toothed rack which is concentrically mated with one of the upper frame longitudinal support brace rods;I) a foot pedal which further comprises a main pedal body, a first shaft sleeve on one distal end that is concentrically mated to said longitudinal rod and a second and longer length shaft sleeve that is concentrically mated to said longitudinal rod and which has a transverse protrusion ending outward in a radial direction and is in contact with said ratchet gear;J) a pair of upper frame support rods that are slidably engaged at their lower distal ends to slotted apertures located at the upper distal ends of the upper longitudinal frame members and are each pivotally mounted at their upper distal ends to one of the side support members of said handle; andK) a pair of lower frame support rods that are slidably engaged at their lower distal ends to slotted apertures located on the lower longitudinal frame members and are pivotally mounted at their upper distal ends to circular apertures located on the upper longitudinal frame members near their lower distal ends. 2. The shopping cart according to claim 1, wherein the upper and lower frame longitudinal members have slotted apertures and locking pins to allow the frame support rods to be adjusted in angular position to the upper and lower frame members. 3. The shopping cart according to claim 1, wherein the web basket may contain between one and twenty additional internal compartmented shopping bags, each bag having at least one carrying handle and each bag further having at least one Velcro style strap to secure to at least one aperture located on the upper rigid frame mounted at the top of the web basket. 4. The shopping cart according to claim 1, wherein the web basket may also contain a plurality of apertures spaced around the periphery on a lower rigid frame mounted at the bottom of the web basket. 5. The shopping cart according to claim 1, wherein the base platform of said web basket has a circular protrusion at the geometric center that is designed to be concentrically mated to a circular aperture located at the geometric center of the basket carrier. 6. The shopping cart according to claim 1, wherein the basket carrier platform has a plurality of thin ribs running along the bottom surface. 7. The shopping cart according to claim 1, wherein the web basket has at least two carrying handles with each handle being rigidly mounted to one of the shorter length sides of the base platform of said web basket. 8. The shopping cart according to claim 1, wherein the elevation mechanism is a ratchet gear driven mechanical system using at least one separate driven toothed gear with a power transmission belt mated to both said ratchet and toothed gears and with a pawl that can be selectively mated and unmated to said ratchet gear using a wireless switching module mounted adjacent to said pawl. 9. The shopping cart according to claim 1, wherein the lower frame support rods include shock absorbing or dampening components to slow down the downward velocity of said shopping cart when it is being lowered in height. 10. The shopping cart according to claim 1, wherein the basket carrier side walls contain a plurality of protrusions for use in securing said web basket when it is in a fully collapsed state. 11. The shopping cart according to claim 1, wherein the foot pedal, when not depressed, is kept in a fixed angular position by at least one pair of torsion springs which are concentrically mated to said longitudinal cross support rod. 12. The shopping cart according to claim 1, wherein the web basket fabric material of said web basket is made of a mesh fabric that is open enough to allow barcode scanners to read barcodes through the web fabric. 13. The shopping cart according to claim 1, wherein the wireless transmitter mounted inside the handle housing and wireless switching receiver mounted adjacent to the pawl as part of the elevation mechanism use communication frequencies within the allowable range of current FCC wireless device regulations. 14. The shopping cart according to claim 1, wherein the wireless transmitter mounted inside the handle housing and wireless switching receiver mounted adjacent to the pawl as part of the elevation mechanism are powered by AA series batteries. 15. The shopping cart according to claim 1, wherein the basket length and width dimensions can be increased by adjusting the position of four pull tabs in an outward diagonal direction so as to further stretch the flexible basket material to achieve a basket volume between approximately 10800 cubic inches and 24192 cubic inches.
