Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

As shown in fig. 1 to 7, the multifunctional luggage case with the front carrying bag is composed of a front case 1, a rear case 2, a coded lock 3, universal wheels 4, a telescopic pull rod 5, a handle 6 and a detachable carrying bag. The detachable satchel 7 is detachably connected with the front box shell 1 through a connecting structure.

The detachable satchel is divided into three specifications, namely a small satchel 7, a middle satchel 8 and a large satchel 9. The detachable satchel comprises a satchel front cover 10, a satchel zipper 11, a satchel back shell 12, a reversible D-shaped ring 13, a T-shaped column 14, a telescopic ring 15, a pull tab 16, a shoulder belt 17 and a hook 18. The T-shaped posts 14 engage with female detents 19 on the front housing 1.

In the using process, if some temporary articles need to be taken and placed, the pulling pieces of the satchel can be pulled open, the front cover of the satchel is turned forwards for a certain angle, the satchel is in an open state, and the zipper is closed after the articles are stored and taken, so that the articles can be taken conveniently and the privacy is protected;

The overall volume of the front carrying bag luggage case is increased mainly in two forms:

the first form is embodied as a carrying bag which is integrally and removably secured within a recessed area defined by the front shell, as shown in figures 1, 2, 3 and 4, the recessed area defined by the front shell may be of different areas, shapes, positions and depths, and the recessed area may be an open area at the sides and corners of the front shell or a non-open area within the front shell; there may be many variations in the size, shape and form of the carrying bag. When the telescopic wall of the satchel is not opened, the whole thickness of the satchel is approximately equal to the depth of the recess of the front box shell, the telescopic wall of the front satchel is attached to the zipper of the satchel, the satchel is not pulled open in normal use, and when extra volume is needed, the volume can be increased by pulling the telescopic wall open.

The second form is characterised by the fact that the depth of the recess in the front box is zero, i.e. the detachable bag is secured directly to the front box 1, as shown in figures 5, 6 and 7, and the volume of the bag itself is a proportion of the overall volume increase of the luggage case, which can be increased again when the bag is again pulled open.

When the satchel is positioned in the sunken area of the front box shell and the telescopic enclosure is not opened, as shown in fig. 8, the whole size of the luggage box is not changed, and the boarding requirement is met when the luggage box passes through the airport security check; when the bag is in the depressed area of the front box and the telescopic enclosure is opened, as shown in fig. 9, the whole volume of the luggage case is enlarged, and the appearance size of the luggage case is changed, so that the bag is taken down from the front box before passing through the airport security check, and the luggage case body still meets the requirement of boarding size; compared with the traditional luggage case, the volume of the luggage case is increased, and compared with the partially telescopic pull rod case, the luggage case can not be contracted to a boarding size when being filled with articles after being stretched and contracted, and only the luggage case can be checked in.

When the depth of the depressed area of the front case is zero, the volume of the whole luggage case of the front carrying bag is increased, and the front carrying bag can be detached in the same way when passing through the airport security check, so that the luggage case body is suitable for the boarding size.
