Abstract

The utility model relates to a folding trunk in daily living articles, which is characterized in that continuous hemming or reinforcing ribs on the top are respectively hinged with four side walls. The lower edges of the symmetrical folding side walls are hinged with a bottom board; the middle part is divided into two parts by a hinge structure. The lower parts of the other symmetrical side walls can rotate around the connecting lines of the upper edges. The trunk has the advantages of simple structure, convenient operation, high integral intensity and low manufacturing cost, and is suitable for various trades.

Description

Folding trunk

The utility model relates to a kind of daily living article, particularly the folding chest.

In the daily life, we often use the chest article-containing, but existing chest is because volume and storage amount are proportional, thereby as the more article of splendid attire, just need the bigger chest of volume, and it is big owing to the space that occupies when the empty van state, carries just very inconvenient, so when needing a kind of storage product are normal chests, not collapsible placement of time spent or the chest that carries.

China utility model CN2104576U makes things convenient for folding boxes to disclose a kind of have segmentation or crimping or reinforcement continuously, a metal or the plastics card that moves about is respectively arranged having on two opposite flanks of oblique hinge, the card that moves about can be free to slide on two lateral edge, and has hinge arrangement on the edge of its four sidewalls.This kind structure has following three deficiencies:

One, because the crimping or the reinforcement at top are not that a kind of integral body is continuous, wherein there is segmentation, this inevitable bulk strength that reduces chest greatly, yielding.

Two, set up the card that moves about owing to can be free to slide, it is very easily displacement in use, makes casing produce deformation, damages article-containing.And the projection of the card that moves about makes it and can not pile up like that as chest.

Three, complex structure

The purpose of this utility model provides the very simple folding chest of a kind of structure.Its bulk strength height, not yielding.

Realize that this purpose can adopt following scheme: crimping that the top is continuous or reinforcement are connected with hinge arrangement with four sidewalls as an integral body, or are connected with ductile structure with Armrest symmetry sidewall, and this lower sidewall can be rotated around the top edge hinge lines.And another its lower limb of symmetrical folding sidewall and base plate hinged in the casing.Its middle part is folded hinge arrangement and is divided into two, and this symmetrical fold sidewall left and right edges has reinforcement.Respectively have continuously or the thrust that is interrupted perpendicular to the folding sidewall direction on the base plate both sides.

The box construction illustrated of this structure is simple, bulk strength is high, not yielding when normally using, folding operation of opening very makes things convenient for, can equally pile up as chest when opening, move, volume only is 1/tens of original volume when folding, cheap, easy to carry.As sidewall being adopted the hollow out form, its weight can reduce greatly, and its intensity is unaffected.

Fig. 1 is the folding chest organigram that the utility model provides.

Fig. 2 is a folding chest method for folding schematic diagram.

Fig. 3 is a schematic diagram behind the folding box body.

Describe embodiment in detail below in conjunction with accompanying drawing.

1 top crimping or reinforcement as shown in Figure 1.2, folding hinge structure.3, folding sidewall reinforcement.4, Armrest sidewall.5, folding sidewall.6, base plate.7, thrust.

Hinged or the toughness of Armrest sidewall 4 and top crimping or reinforcement 1 is connected among Fig. 1, its underpart can be that axle rotates around the top edge connecting line, when it was vertical with base plate 6, folding sidewall reinforcement 3 and thrust 7 played the restriction to its motion jointly, make it to be fixed on vertical direction.Thrust 7 height is by the toughness of material decision of Armrest sidewall 4, and it be continuously or the state vertical folding sidewall 5 that is interrupted, determines apart from the thickness of base plate left and right edges distance by Armrest sidewall 4.

Folding sidewall 5 is hinged with top crimping or reinforcement 1 and base plate 6 respectively.Wherein separated be divided into two planes by folding hinge structure 2 hinged.

Its operating process is as shown in Figure 2:

When folding: with Armrest sidewall 4 in opposite directions direction push away.Because the 4 toughness of material effects of Armrest sidewall make its lower limb slip over thrust 7, serve as axially to go up to rotate with the top edge hinge lines, again with folding sidewall 5 in opposite directions direction push away, owing to the move toward one another of folding hinge structure 2 makes folding box body.

Folded box section as shown in Figure 3, its opening procedure is opposite with said process.

This folding chest can be added a cover by known manner in addition.

Tank material can adopt plastics, also can adopt light-weight metal, wood etc.Can adopt engraved structure for reducing by four sidewalls of chest weight.Its intensity is unaffected.
