Description

The variable-displacement chest

The present invention relates to a kind of variable-displacement chest, it by one by two firm mutually hinged cores that minute framework is formed, to minute framework as two supports that constitute the shell of chest inner chambers.

Traditional chest, for example suitcase or suitcase, the volume of chest inner chamber is constant mostly.Therefore must use different chests for different baggage capacitys.For example, just needed less than the vacation trip that continues several weeks in order only to continue the needed chest of going on business of a few days.The purchase commodity of a plurality of different size chests is very high.In addition, when depositing these chests, need take many spaces.

By the more known different chests of prior art, their cavity volume is variable, in order that a kind of chest that can hold different luggage amounts is provided.For example introduced a kind of chest in German utility model GM7726305, its dressing amount can increase as required step by step, until making capabilities double.For this purpose, at the bottom of case lid and case, respectively be provided with dark especially superimposed part.What German utility model GM7541679 was related is a kind of have two firm shells and chest that flexible intermediate portion is divided.

Yet these two kinds of schemes all have shortcoming, and superimposed or flexible mid portion has adverse influence for the stability of chest.Superimposed or flexible mid portion has reduced the chest global stiffness.Can make the chest distortion outside under Fu He the effect.Therefore, or chest itself is impaired, or the article that are contained in the case are damaged.

Germany open file DE3343068 discloses a kind of suitcase with modular organization.Wherein, be provided with the part of lid in the both sides of core.The part of these lids can be connected with core is removable.Therefore the part that just might replace the lid of certain depth with the part of the different lid of the degree of depth.The part of these lids is hinged by hinge and core.When opening and closing chest, these hinges are subjected to high load.When hinge design is detachable connector, they is become reduce this type of chest weak link in service life.

In German utility model G8308483, chest have two mutually hinged and can be each other with respect to hinge closed firm framework, framework is as two supports that surround the shell of chest inner chamber.Wherein, shell can be expanded, and can adapt to needed at that time chest cavity volume in order that constitute.These shells are made by flexible material, thereby have reduced the stability of chest.

The objective of the invention is to create the chest that a kind of its capacity can adapt to relevant requirements, meanwhile this chest not only firmly but also can be easy to use.

This purpose reaches by a kind of variable-displacement chest, and it has a core, and core is by two firm and mutually hinged forming a minute framework.To the support of minute framework as shell, shell and the inner chamber that minute framework is constituted jointly chest.Framework has the overall shape of rectangle usually, and wherein, each has one on hand to a minute framework, and the hinge edge that is in relative position on hand, and two sides opposite each other.Framing component can global formation.According to the present invention, shell detachably is connected a minute framework with core.

Therefore just might adopt the shell of different depth to be connected with same core.In this way, the chest capacity can be adapted to the volume of luggage.The common shell of being made by rigidity plastics, the core made from light metal or rigidity plastics constitutes a firm chest jointly.In chest time spent not, the different shell of the degree of depth is intussusception mutually.So shared space when depositing by chest of the present invention is than a plurality of needed space of traditional chest much less with different chest capacity.

Each preferably has the mechanism of bikini fixed housing at least to minute framework.Shell was fixed on each at detachably 3 o'clock about in minute framework, for example can connects and realize by buckle.Should be noted that shell should have enough rigidity, so as can be with core minute framework is constituted a firm chest inner chamber.

Each has a groove to the inside that minute framework is preferably in hinge edge, and the flanging of each shell inserts in this groove.In the inside on hand on the other side, has a mechanism that is used for fixing relevant shell at least.When frequently changing shell, may connect inefficacy owing to buckle take place fatigue of materials.So, come from stable reason, for shell is fixed in the core, would rather adopt other mechanical measure.

Shell preferably has a circular fold or ring edge, and its retaining leans against relevant on minute inside of frame ring edge, and take a sound card and be combined in protruding back, these projectioies are arranged in relevant in minute framework with being parallel to ring edge.By these buckle projectioies, shell is fixed on its stop dog position.This ways of connecting allows to change fast shell, so chest is easy to use.

Preferably be provided with a groove on the rib, flange set on the casing component flanging can insert in this groove.

Be used for each shell is fixed on relevant mechanism to minute framework, preferably by one of following mechanism or by at least two in these mechanisms constitute: spring, hinge, cam bar, angle clip, rocking bar, latch and/or slide block.Be used for each shell is fixed on relevant best mechanism to minute framework, expression in the accompanying drawings.

Handle preferably is hinged on the core.Also can on each shell, adorn a handle.These handles should be arranged on the shell so in this case, that is, these two handles have constituted a single handle under the state that chest assembles.

Be preferably at least one shell and be shaped on groove, groove can be closed with the rotating lid of energy, and lid can align with the outer contour shape of shell.Groove is used for depositing some apparatus, and they should be easy to take between the operating period at chest, for example paper, key, cuticle clip, spectacle case etc.
