Benefits of technology

The goal of this invention is to create a hard suitcase that is easy to open and close.

Problems solved by technology

But a side wall near the top wall is easy to deform so that wheels can not be installed thereon.
However, as known, two pairs of wheels with greater spacing therebetween will provide more stable support for the hard suitcase, but spacing between the two pairs of wheels installed on the lower portion of the side wall is not sufficient, thus the hard suitcase is not stable.
However, due to the suitcase body of the hard suitcase is made by plastic molding, but such a suitcase body with remained top wall is hard to be formed by the plastic molding process.
Of course, user also can hold the cover with a hand, and then take or put articles with the other hand, which is easy to operate and occupy less space, meanwhile, the articles in the accommodating space will not be exposed, which adequately protects user's privacy.

first embodiment

[0035]FIGS. 2 to 8 show a hard suitcase A00 according to the present invention.

[0036]As shown in FIGS. 2 to 4, hard suitcases A00 includes a suitcase body 100, and four wheels 200, wherein, the suitcase body 100 includes an upper suitcase body 110 of hard material, a lower suitcase body 120 of hard material and a cover 130. The upper suitcase body 110 having a top wall 112 and upper side walls 111 which form an upper cavity 110a with an opened bottom, the lower suitcase body 120 having a bottom wall 122 and lower side walls 121 which form a lower cavity 120a with a closed bottom and an opened top, peripheries of the upper suitcase body 110 and the lower suitcase body 120 are connected in a permanently closed manner, and the upper cavity 110a and the lower cavity 120a are communicated with each other to form an accommodating space 100a of the suitcase body 100, the accommodating space 100a is used for saving articles. An access opening 113 is defined in the top wall 112 by removing a...

second embodiment

[0043]FIGS. 9 and 10 show a hard suitcase B00 according to the present invention.

[0044]The difference between the hard suitcase B00 of the second embodiment and the hard suitcase A00 of the first embodiment is that the connection type of the upper suitcase body 110′ and the lower suitcase body 120′ of the hard suitcase B00 is firm butt connection.

[0045]Concretely, the upper suitcase body 110′ is butted up against the lower suitcase body 120′, a lower edge of the upper side walls 111′ and an upper edge of the lower side walls 121′ are butted to form a contacting line α. The hard suitcase B00 further includes a circular enclosed strip 140′, which covers the contacting line α and firmly connected with the upper side walls 111′ and the lower side walls 121′. Concretely, the circular enclosed strip 140′ includes an inner enclosed strip 141′ covering the contacting line α at an inner side of the upper side walls 111′ and the lower side walls 121′, and an outer enclosed strip 142′ covering...

third embodiment

[0046]FIGS. 11 and 12 show a hard suitcase C00 according to the present invention.

[0047]The difference between the hard suitcase C00 of the third embodiment and the hard suitcase A00 of the first embodiment, the hard suitcase B00 of the second embodiment is that the connection type of the upper suitcase body 110″ and the lower suitcase body 120″ of the hard suitcase C00 is firm sleeve connection.

[0048]Concretely, the upper suitcase body 110″ and the lower suitcase body 120″ are connected in a sleeve manner. Either the upper side walls 111″ or the lower side walls 121″ partially sleeves the other one, the sleeve connection of them forms a contacting area with either the upper side walls 111″ or the lower side walls 121″ being located at the inner side and the other being located at the outer side. The upper side walls 111″ and the lower side walls 121″ are firmly connected by machine sewing thread at the contacting area, so as to realize firm sleeve connection of the upper suitcase b...

Abstract

A suitcase body of a hard suitcase includes an upper suitcase body having a top wall and upper side walls which form an upper cavity with an opened bottom, a lower suitcase body having a bottom wall and lower side walls which form a lower cavity with a closed bottom and an opened top, and a cover. Peripheries of the upper and lower suitcase bodies are connected in a permanently closed manner, and the upper and lower cavities are communicated with each other, and an access opening is defined in the top wall by removing a part of the top wall, the rest and a portion of the upper side walls form an installation area for installing partial wheels, the rest of wheels are installed on the lower suitcase body. Such a simple structure of the suit case is convenient to take and put articles, which is easy to operate.

Description

FIELD OF THE INVENTION[0001]The present invention relates in general to a suitcase, and more particularly to a hard suitcase, which is easy to open and close.BACKGROUND OF THE INVENTION[0002]Suitcases, so-called travel suitcases, or luggage, are used to save articles needed on the journey so as to facilitate travel.[0003]The suitcases include hard suitcases and soft suitcases according to their different materials of housings.[0004]Generally, the soft suitcases have a suitcase body made of fabric materials, by which their manufacturing process is simple, and their structures or shapes are various. When many articles are accommodated within the suitcase body, the shape of the suitcase body may change slightly so as to save more articles. However, the soft suitcase could not adequately protect the articles when it is extruded or collided, as an extrusion force or collision force will be passed to the articles directly.[0005]While the housings of hard suitcases are made of hard materia...
