Abstract

An expandable bag comprising an outer bag body (1) and an inner bag body (2). One end of the outer bag body at the perimeter thereof is connected to one end of the inner bag at the perimeter thereof via a soft connecting part (3). The bag also comprises a telescopic rod (4). One end of the telescopic rod is connected to the inner bag body, while the other end is connected to the outer bag body. The bag expands an accommodation space by using a nested structure; also, the bag has a reduced footprint when stored.

Description

Expandable luggage

The invention relates to a luggage used in daily life, in particular to a expandable luggage.

Background technique

Luggage is an essential item in people's market life, and its main function is to store items. When we have a large enough storage space, we often need a bag that is large enough to hold more items. However, the volume (volume) of existing bags is always custom-made, and the manufacturer of the luggage rarely makes a larger volume (capacity) for the customer. The reason for customizing such specifications is to meet the needs of their use. . For example: The international standard baggage check box is three-piece baggage with a length of three sides and no more than 158 cm. In order to achieve this standard, the volume (volume) of the bag will be fixed with the relative length of the three sides. Luggage often can no longer accommodate more items.

In the current situation, in order to accommodate more items, people can only buy more bags. However, as a result, when these bags are no longer used, their own storage also requires a large space, causing greater inconvenience.

Summary of the invention

The object of the present invention is to provide a expandable bag, which mainly solves the technical problem that the volume (volume) of the existing bag is relatively fixed and cannot accommodate more articles, and the nesting structure can increase the storage space of the bag. It is convenient for the storage of the luggage itself, and does not need to occupy more space when it is stored.

In order to achieve the above object, the technical solution of the present invention is.

The expandable bag is characterized in that: it comprises an outer box body and an inner box body, and one end of the outer box body is connected with one end of the inner box body through a soft connecting portion; and it also has a telescopic rod, the telescopic rod One end is connected to the inner box and the other end is connected to the outer box.

The expandable bag is characterized in that: the telescopic rod is composed of an outer tube, an inner tube and a positioning element for fixing the telescopic position of the inner and outer tubes; the inner tube end is connected with the inner box body, The other end of the outer tube is connected to the outer box.

The expandable luggage bag is characterized in that: the telescopic rod is horizontally disposed and/or vertically disposed in the outer casing.

The expandable bag is characterized in that: the bag is provided with a nesting structure of a plurality of outer boxes and inner boxes, and horizontal and/or vertical sets are used between the multiple outer boxes and the inner boxes. Rod.

The main advantages of the invention are summarized as follows:

1. The invention sets the luggage to be an inner and outer nesting structure which can expand and expand the storage space through the telescopic rod, and the luggage can be compressed and extended, which is convenient for placing articles of different sizes, and is convenient for the storage of the luggage itself.

2. The invention can not only be pulled up or widened in one direction, but also can expand the storage space in multiple directions through multiple nesting structures (for example: simultaneously pulling up or widening), therefore, technically more Great scalability.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view showing the structure of a first embodiment of the present invention.

Fig. 2 is a schematic view showing the nesting structure of the inner and outer casings in the first embodiment of the present invention.

Fig. 3 is a view showing the structure of a telescopic rod in the first embodiment of the present invention.

Fig. 4 is a view showing the state of use of the embodiment 1 of the present invention.

detailed description The invention is further illustrated below in conjunction with the drawings and various embodiments.

Example 1

Referring to Figures 1-3, which is a schematic structural view of the embodiment 1 of the expandable package of the present invention, the bag can be expanded and contracted in the height direction. As shown in FIG. 1 and 2, it comprises an outer casing 1 and an inner casing 2, and an outer periphery of the outer casing 1 and a lower outer periphery of the inner casing 2 are connected by a soft connecting portion 3; and it has a telescopic rod 4, which The upper end of the telescopic rod 4 is connected to the inner box 2, and the lower end is connected to the bottom of the outer box 1.

As shown in FIG. 3, the telescopic rod 4 is composed of an outer tube 41, an inner tube 42 and a positioning element 43 for fixing the telescopic position of the inner and outer tubes; the upper end of the inner tube 42 is connected to the inner box 2, The lower end of the outer tube 41 is connected to the bottom of the outer casing 1.

In the first embodiment, the telescopic rods 4 are vertically disposed in the outer casing 1 to ensure that the inner casing can be highly expanded in the vertical direction with respect to the outer casing. As shown in Fig. 4, when the inner box is extended upward by the telescopic rod, the storage space of the box is expanded to help accommodate more items. After the storage work is completed, the inner box can be returned to the outer box for the storage of the luggage, so that it does not occupy a larger storage space, and therefore, the operation is very convenient.

As a variation of the first embodiment, the telescopic rod 4 may be horizontally disposed in the outer casing 1 by two or more pairs, thereby ensuring that the inner casing can be expanded in the horizontal direction relative to the outer casing. It can also play a role in expanding the storage space.

Example 2

It is a further improvement based on the first embodiment. The main improvement is that the inner box body can be further nested with an inner box body, and another inner and outer box body nesting structure is formed by nesting each other.

Horizontal expansion and/or vertical expansion between the multiple outer casing 1 and the inner casing 2 Rods can also use two-fold (multiple) vertically set telescopic nesting structures and/or two-fold (multiple) settings for horizontal telescoping nesting.

When in use, the bag can be further expanded in width or height, or can be expanded after a high degree of expansion (ie, three-dimensional expansion).

The above is only the preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, the equivalent changes and modifications made by the content of the patent application scope of the present invention should be the technical scope of the present invention.
