Benefits of technology

"The present invention provides a luggage bottom frame that has simplified components and highly adaptable molds, making it cost-effective. The frame is modular, easy to assemble, and fast when different sizes are required, increasing production efficiency. The frame includes four corner units, each with an inner wheel skeleton, an outer wheel skeleton, a link unit, and a luggage body layer. The inner wheel skeleton has a board with two connection sections that can connect to a link. Overall, the invention offers advantages such as cost reduction, cost effectiveness, and production efficiency increase."

Problems solved by technology

Typically, bottom frame is molded and mold for bottom frame is very expensive.
As a result, the manufacturing cost is increased.
Such structure of bottom frame inevitably not only increases the cost of preparing molds but also causes problems associated with mold management, manufacturing time delay, etc.

Embodiment Construction

[0014] Referring to FIGS. 1, 2, 3, and 4, a luggage 1 incorporating a bottom frame 100 in accordance with a preferred embodiment of the invention is shown. The bottom frame 100 comprises four corner units 101 each including an inner wheel skeleton 10, an outer wheel skeleton 20, a link unit 30, a wheel unit 40, and a luggage body layer 50. The inner wheel skeleton 10 comprises a board 11, a flange 12 formed around an outer wall of the board 11, a first connection section 13 extended from the board 11 toward a first direction the first connection section 13 having a bore 131, a second connection section 14 extended from the board 11 toward a second direction perpendicular to the first direction, the second connection section 14 having a bore 141, and a plurality of holes 15. The outer wheel skeleton 20 comprises a board 21, a plurality of threaded holes 22 aligned with the holes 15 of the inner wheel skeleton 10, a central recess 23 on the board 21, a through hole 24 on the recess 23...

Abstract

Provided is a bottom frame mounted on a bottom of a luggage. The bottom frame includes four corner units each comprising an inner wheel skeleton, an outer wheel skeleton releasably secured to the inner wheel skeleton, a link unit releasably secured to the inner wheel skeleton, and a luggage body layer sandwiched between the inner wheel skeleton and the outer wheel skeleton. The invention can simplify components of the bottom frame and carrying out highly adaptable molds so as to be cost effective and increase production efficiency.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of Invention [0002] The present invention relates to luggage structure and more particularly to a modular, highly adaptable frame mounted on bottom of luggage such that advantages including manufacturing flexibility and cost effectiveness can be obtained. [0003] 2. Description of Related Art [0004] Luggage is a case for storing personal belongings while traveling. Conventionally, bottom frame is adapted to support the whole weight of luggage and is connected to wheels. Typically, bottom frame is molded and mold for bottom frame is very expensive. Also, bottom frames of different luggage cases are molded by different molds due to different sizes of bottom frames. As a result, the manufacturing cost is increased. In other words, different molds are required for different luggage bottom frames. Such structure of bottom frame inevitably not only increases the cost of preparing molds but also causes problems associated with mold management, man...
