Abstract

To provide a shopping cart with a movable upper loading platform, which can easily carry luggage in and out of the lower loading platform. [Solution] Ratchet mechanisms C are provided in two places on the shopping cart, and the upper loading platform H is fixed at an upward angle of approximately 30 degrees, making it easy to carry luggage in and out of the lower loading platform. When returning the upper loading platform to its original position, the upper loading platform, which has been fixed by the ratchet mechanism, can be easily released by pulling the release lever, and the shock absorber F is activated, allowing the upper loading platform to be returned to its original position smoothly without any shock.

Description

[Background technology]

[0001] When carrying items in and out of the lower loading platform of a shopping cart at a supermarket, etc., you should be in a half-squat position. People had to bend over or kneel on the floor to load and unload luggage from the lower cargo compartment. [Prior art documents] [Patent documents]

[0002] [Patent Document 1] Patent Publication No. 2020-147127 [Non-patent literature]

[0003] [Non-Patent Document 1] Yamato Sangyo Co., Ltd. Homepage Shopping Cart SV502-C100 Summary of the Invention [Problem to be solved by the invention]

[0004] The problem to be solved is that the user has to be in a crouching position when loading and unloading items from the bottom of the shopping cart. It is not easy to carry luggage in and out of the lower loading platform, especially when the luggage is heavy or when the user is elderly or female. Such movements can be difficult and in some cases can even result in injury, such as a strained back. [Means for solving the problem]

[0005] In this device, the upper loading platform F can move upwards about 30 degrees around the rotating mechanism parts A and B installed on both ends of the shopping cart handle, and has a ratchet mechanism consisting of parts C, D, and E. The structure allows the seat to be lifted and fixed at an angle of about 30 degrees upwards, and the gap to the lower loading platform H is expanded to some extent, making it easy to carry heavy luggage or when the user is elderly or female. This makes it easier to carry in and out luggage. Effect of the Invention

[0006] The shopping cart of this invention looks almost the same as existing shopping carts, except that the upper loading platform is equipped with a ratchet function that allows it to be moved and fixed. Users can use it without feeling uncomfortable, and when returning the upper loading platform to its original position, it can be released by simply squeezing the release lever G, and the shock absorber E will still function in that case. The upper loading platform can be smoothly returned to its original position without any impact, improving the convenience of the shopping cart. [Brief description of the drawings]

[0007] [Figure 1] FIG. 1 is an explanatory diagram for explaining a rotation mechanism that can fix the upper platform of a shopping cart at an upward angle of about 30 degrees. [Diagram 2] FIG. 2 is an explanatory diagram for explaining the ratchet function of the movable part of the shopping cart. [Diagram 3] FIG. 3 is an explanatory diagram for explaining the function of returning the upper platform of the shopping cart to its original position when the mobility is released. [Figure 4] FIG. 4 is an explanatory diagram for explaining the function of the shock absorber when the upper carrier of the shopping cart is returned to its original position. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] First, a shopping cart according to an embodiment will be described with reference to FIGS.

[0009] By lifting the upper loading platform H upward by about 30 degrees, the rotation mechanism parts A and B installed on the upper loading platform are operated, and the ratchet mechanism part C moves from the lock position of the rotation mechanism part A to the lock position of the ratchet mechanism part C. By moving the upper platform to the B lock position and fixing it at about 30 degrees upward to maintain a certain amount of space with the lower platform, it is possible to carry in and out of the luggage on the lower platform. The ratchet spring E has tension that maintains the A and B locked positions when the ratchet C is in operation.

[0010] The shopping cart according to the embodiment will be described with reference to FIGS.

[0011] When returning the upper loading platform H to its normal position from the fixed position at approximately 30 degrees upward, the ratchet part C, which is locked at approximately 30 degrees upward by the rotation mechanism part B, By gripping the handle G of the ratchet function release mechanism D, G, the D part pulls the ratchet part C upward and unlocks the locked rotation mechanism part B. The upper loading platform H is designed to be released and return to its normal position by using its own weight up to the position of the rotation mechanism A. In addition, by installing shock absorbers F in two places, the upper cargo platform can be returned to its normal position smoothly without giving any shock to the upper cargo platform.

Claims

[Claim 1] The upper platform of the shopping cart is equipped with a rotating mechanism with a ratchet function that can be fixed at about 30 degrees upward, creating a certain amount of space between the lower platform. This shopping cart has a lower loading platform that allows even elderly and female users to easily carry heavy luggage in and out.
