Description

FIELD OF THE INVENTION

The present invention is in the field of bags in general. More particular, it is directed to a novel multifunctional assembly for bags comprising at least one replaceable panel and at least two directional rail profiles for assembly of the at least one panel onto the bag.

BACKGROUND

Modular bags that allows addition of parts and components to standard bags are known in the art. Such modular bags provide solutions that are sometimes cumbersome and change the entire structural appearance of the bag, expensive and therefore they are unreachable to most people. One optional solution is described in FR978474 that is a limited solution for handbags that allows replacement of the entire bag wall for aesthetic reasons. As such the replacing panel is limited to be replaced only on two walls of the bag. In more detail, this patent (denoted hereinafter: “474”) is directed to a handbag with transformations, while the present invention may be implemented in all kinds of bags including handbags, backpacks, luggage's, purses, and else. The handbag disclosed in 474 appears at first, as a common model while the bag with the multifunctional replaceable panel has a unique appearance with the replaceable panel assembly visible onto it wither with replaceable panel within it or without a panel, having the bag's fabric visible between at least two rail profiles. Additional difference is that in 474 all materials can be used while in the present invention only flexible materials that maintain the soft structure of the bag are suitable. Also, in the 474 patent the two slides are on the front and back sides only, a series of two-sided panels, or one side, visible or hidden depending on the model, while in the present invention the number of replaceable panels is not limited to one or two, as it is not replacing the side wall of the bag but rather additional part, and it may be positioned on each and every side of the bag. From the same reason, in 474 the slides are designed as two flat portions of the bag (front and back) and have exactly the shape of the bag. The replaceable panels of the present invention have only partial shape of the front/other surface of the bag.

Some further attempts have been made as described in the following patents and applications that may be relevant to the field of the invention: FR1108023(A), CN105708070(A), U.S. Pat. No. 2,302,560(A), and U.S. Pat. No. 2,522,549(A).

In all references mentioned above, the frame holding the slides and the slides, well as the mechanism for attaching the slide are very rigid, and a have a significant appearance on the bag, like external faces, and as such interrupt with the soft structure of the bag and its original design. The rigid structure is usually encompassing the entire surface of the bag side to either cover it or replace it.

Thus, there is a constant need for a simple and intuitive solution for adding functionalities and changing the appearance of a bag without changing the bag's flexible structure and soft appearance, that will be easy to use and achievable to everyone. The present invention is aimed to provide such a flexible, simple and low-cost solution that doesn't interrupt with the basic bag structure.

The present invention provides in one main aspect, a novel multifunctional replaceable panel assemble that is formed from soft and flexible materials which doesn't impact the flexibility and natural soft filling of the bag, like the other solutions available in the market, and can be integrated into the bag, like part of its construction. The bag having the novel multi-functional replaceable panel assembly of the invention maintain its natural look and function with or without the use of the replaceable panels.
