Description

Detachable stackable crate

Technical field

The present invention relates to a kind of crate, the crate of this type mainly by timber or MDF (medium-density fiberboard) or The combination of the two constructs, and is constructed sometimes by metal, and particularity is that metal assembly can not touch content.

Background technique

For packing any kind of fruits and vegetables product, cardboard case solution especially has cost-effectiveness, but its Disadvantage be it is extremely sensitive to wet condition, therefore in order to prevent they degrade, usually use plastic overmold cardboard, to make product It is more expensive.In addition, in order to realize firm assembling, it is necessary to adhesive is used between the different piece for constituting crate, from And that additional adhesive member must be used.

There is also by timber or wood by-product --- such as glued board, medium-density fiberboard or other similar classes The crate solution of type --- manufacture, by being formed by stitching part secured to one another, wherein needing device and matching Part carrys out stitching crate.In addition, crate assembling needs heavy duty equipment, therefore crate must assemble in the factory；By This, even empty crate also must be with the position transport of its assembling, to occupy big quantity space.In stitching solution In the case of, used metal nail is also unfavorable for recycling and getting rusty easily, and due to they are contacted with food and in many It is not expected in the market or by total ban.

Patent document WO 2008/071813 partly solves these problems, discloses a kind of crate, profile is by dividing Not Dui Yingyu the larger side of rectangle and the side of smaller side and end formed, to form crate.Smaller side has hook, institute It states hook and is couple to the block to form crate angle.However, in this document, described piece has the wedge for accommodating tab, described Tab is used to limit the hooking of each side.This structure weakens assembly, its own is defined because according to, hooking quilt It is configured to extremely weak hook, therefore minimum transverse movement may cause hooking rupture.Further, since outer surface has irregularly Surface, therefore when crate stacking and when contacting with other crates, these tightening members are easy to because generating during transport It moves generated dynamic load and ruptures.

In addition, this structure and since the configuration of block is so that extremely difficult to stack crate, because on the upper surface of block Contact surface is minimum.

It it is known that the patent document WO2009/060109 for attempting to solve the stack-up issue of such crate.It is practical On, it is sometimes desirable to a kind of structure allows to stack a large amount of crate to save storage surface, for this purpose, this patent document limits The block of crate or the extension in corner are determined.However, simply extending and meaning entirely to load without any additional attachment members It is only supported on the upper surface of block, and for efficient vertical stacking, it is necessary to which crate is perfectly aligned, and otherwise they will be because not Good load distribution and rupture.

Finally, patent document EP 2 604 541 describe it is a kind of without block or the packaging or crate in corner, in heap Naturally there is structure problem, because load falls on each side and bottom of crate, so that these elements are in crate when folded Become load bearing element when vertical stacking.However, such crate has from bottom and each side several elements outstanding, It moves, vibrate during stacking so as to cause crate and finally rupture.

Generally speaking, there are two basic technique problems for mentioned patent document tool:

A) during its manufacture, in order to be combined together all parts correctly, in addition to mechanical tolerance should it is smaller other than It has no option, therefore the part for constituting crate must cut (such as being cut by laser) with exquisite system, to make its system It is more expensive to make process.

B) in vertical stacking, when being carried to it, especially when crate is stacked for transport, crate It can bounce up and down, may move suddenly or they are not only aligned correctly, so as to cause tightening member rupture.

This last one problem means that crate can bear the stress bigger than the stress that during the design calculates, it is meant that it Possibly even rupture.In addition, most of crates have several protruding portions, this can amplify stack-up issue, so that vertical stacking It is more difficult, and crate it is more easily rupturable (rupture be understood not only in the sense of rupture itself, being also understood as crate becomes not Cheng Zhi Angle).

Document CH589542 discloses a kind of collapsible Stackable container, and with bottom plate, side wall is attached to the bottom plate.Often There is common connector to adjacent sidewall, the common connector acts also as the supporting element of container.This supporting element is removably solid Surely side wall and bottom plate are arrived, and is held in place side wall, a part can be formed on each edge of each side wall, for connecting Forced engagement in device, and form the guiding piece of the latter.Connector can be ducted body, have slot open at one end.It is described Slot accommodates guide rail and length having the same.

In addition, document WO2016059440 discloses a kind of sheet material connector of the clamping piece of use to assemble crate, It is made of the clamping piece comprising slit with protruding portion, and the protruding portion utilizes the corresponding fluting along its edge to keep timber Or other materials sheet material.If the connection of clamping piece to sheet material is fixed by slit in the deformation at the place of doing or using auxiliary member. It can be used for generating the box, crate and container for packing fruit and vegetables using the sheet material connector of clamping piece.

Summary of the invention

It is described other than forming the plate of crate bottom it is an object of the present invention to a kind of detachable stackable crate Crate includes four corner blocks to form the angle of crate, has conventional rectangular structure, has and is respectively individually attached to often Two larger sides (referred to as longitudinal component) and two smaller sides (referred to as end pieces) of a block.In the present description, term side Correspond to the assembly formed by two longitudinal components and two end pieces with wall, that is, forms the assembly of each side of crate.

As mentioned, there is triangular configuration described piece, and preferably isosceles right triangle configuration is (that is, have one A right angle, and two sides for forming right side of the triangle are equal).In the present description, it should be appreciated that the triangle of block It is any to refer to the triangular configuration that must be understood as referring to block.Therefore, hypotenuse refers to form the triangle of the configuration of block The larger skirt of shape, and the crate diagonal line at the right angle perpendicular to connection two opposite blocks.Therefore, it can also be appreciated that the bevel edge of block It is the inner surface of block, and therefore the right-angle side of block is each piece of side or outer surface.

The inner surface of block includes corresponding slot or elongate mounting holes, and one is used to accommodate neighbouring longitudinal component, and another is used In receiving approach end component.The lateral tab of longitudinal component and end pieces will be contained in slot, and depend on that longitudinal direction will be formed The number of the part of component or end pieces, it is possible to provide more multiple-grooved or elongate mounting holes.Therefore, this structure means to be different from affiliated The crate well known in the prior art in field, described piece is located at the fixed circumferential exterior of each lateral confinement.Therefore, longitudinal component and end It is protected due to this structure attachment regions between part.

Thus structure realizes following aspect: (i) avoids fastening crate using nail；And (ii) crate is in structure It is enhanced, since each piece of inside is inserted into each side, described piece can prevent each side from opening wide (that is, preventing from becoming not Cheng Zhi Angle).

In addition, it is a further object of this invention to detachable crate object of the invention can stack easily.For this purpose, described Block includes the recess portion in the upper and lower surfaces of block, wherein the recess portion is complimentary to one another so that when crate self When stacking, described piece is fully mated.Equally, these recess portions have inclined wall, so that being easier to stack crate And it provides and preferably places.In addition, this system stacking is complementary with the inclined-plane formed at each side inferior horn, to form a kind of false ladder Shape.It must further be noted that block length be greater than each side height, therefore the bottom of crate and each side not with its right above or Each side of the crate of lower section or bottom contact.Under such configuration, as indicated, the contact surface in block increases and allows lath The weight of case is directly delivered to ground by block, and described piece works as the column of any structure or pillar, and crate Wall or bottom need not facilitate this purpose in any way.

An object of the invention is to may be easily assembled crate and detachably.For this purpose, there are two main assembly orientations With two auxiliary assembly orientations, a pair of block of relative angle is assembled first；Intermediate point is found in conjunction with another pair block.Therefore, assembling side To consistent with longitudinal component and end pieces bisector.In addition, the bottom of crate is at each of which in order to be easier the assembling While including multiple withholding bayonet type fasteners, the bayonet type fastener is oriented towards main assembly orientation.

Finally, the bottom of crate has withholding face in corner.These withhold face (having inclined plane shape) against block Inner wall, so that they help to prevent crate from scattering, this is different from conventional crate, in conventional plate after crate assembling In bar case, bottom is assembled in the plane below block, bottom can be become load bearing element when its shortcoming is that stacking, from it is long-range come Its structure can be weakened by seeing.

No matter in short, its specific advantages and technical effect, the element of all instructions cooperates with side after crate assembling The equalizing properties for maintaining crate are helped, this accounts for individual and vertical stacking crate situation.Therefore, the position of block, Longitudinal component and end pieces are included in the slot to be formed, make the present invention in conjunction with recess portion and mentioned structural configuration The assembling of crate and more advantageous using the content that describes than in the prior art.

As in the accompanying drawings as it can be seen that crate object of the invention has conventional rectangular configuration in such product, And including two longitudinal components (1,1') relative to each other, two end pieces (2,2') relative to each other, bottom (3) and it is located at each Four blocks (4) at angle, to form the crate.

There is triangular configuration each piece (4), specifically, being in a preferred embodiment isosceles right triangle.Therefore, Each piece (4) includes top (41), inner surface (42) and two outer surfaces (43), wherein the surface (42,43) respectively with formation The projection of the hypotenuse of the configuration of block (4) and the projection of right-angle side are corresponding.

In the inner surface (42) of each piece (4), there are two elongate mounting holes (4a) perpendicular to one another, wherein each thin Long mounting hole (4a) is dimensionally consistent with the tab (1a, 2a) of the side of crate (1,1', 2,2').Therefore, portion longitudinally in each The coupling in the elongate mounting holes (4a) of block (4) of the tab (1a, 2a) of part (1,1') and each end pieces (2,2').Therefore, will Elongate mounting holes (4a) are defined as being disposed for coupling the slot of the tab (1a, 2a) of each side (1,1', 2,2').

In order to be correctly suited in the elongate mounting holes (4a) of block (4), tab (1a, 2a) has the appearance than block (4) The small length (1x, 2x) of the length in face (43).Equally, in this particular embodiment, the height (1y, 2y) of tab (1a, 2a) about Equal to or more than the half of the height of corresponding longitudinal component (1,1') or end pieces (2,2').It must be taken into consideration under any circumstance It arriving, the height (1y, 2y) of tab (1a, 2a) is bigger, and it is bigger with the contact surface of block (4), and therefore the feature of the attachment is got over It is good.

Using described structure, block (4) is located at the circumferential exterior limited by side (1,1', 2,2'), so that generated Wall can be better against the stress generated on the direction perpendicular to the wall.

Described piece includes additional fastening member (44), consists essentially of the mechanical organ for fixing each side position.It is logical Often, these fastening members (44) are made of multiple through-holes between outer surface and side, can pass through interior table in some cases Face, and in other cases, tightening member is hidden by the inner surface.This some holes can be previously fabricated, or can introduce mechanical member It is manufactured while part, this depends on selected solution.In another embodiment, such as the case where metal nail, it is necessary to also Any hole may be not present.The major function of these fastening members (44) is to enhance the balanced of crate after crate is formed to belong to Property, the pressure for the product for preventing it from being accommodated can actually separate each side (1,1', 2,2') and their relevant block (4).

In a particular embodiment, block further includes the hole on its outer surface, and the hole is vertical with outer surface and extends through interior table Face, consistent with other holes on side, wooden adapter accessory is placed in this some holes, and thus provides the material by single type Expect structuring and completely dismountable crate.

As most preferably seen in fig. 2, there are two main installation directions (200,201) and two auxiliary assembly orientations (202, 203).Assembling sequence starts from assembling two its corresponding sides of block (4) (1,1', 2,2') in relative angle.Principal direction (200) with It is consistent with the bisector that end pieces (2) are formed by longitudinal component (1), and principal direction (201) with by longitudinal component (1') and end (2') bisector that part is formed is consistent.Meanwhile assist direction (202) with by longitudinal component (1) and end pieces (2') formed etc. Separated time is consistent, and assists direction (203) (1') consistent with bisector that end pieces (2) are formed with by longitudinal component.Of the invention Crate object has the particularity including single assembly orientation.

In addition, as in different figures as it can be seen that bottom (3) include multiple tightening members in bayonet type fastener forms (31), the slot (1c, 2c) of quantity and longitudinal component (1,1') and end pieces (2,2') is consistent.

These slots (1c, 2c) are configured as four-sided openings, with component longitudinally in each (1,1') and end pieces (2,2') Downside alignment and parallel.The particularity of tightening member (31) is that they, which have, is parallel to main assembly orientation (200,201) Positionable wall.Therefore, as most preferably seen in fig. 2, the withholding tightening member (31) of first longitudinal direction component (1) is towards being conducive to main group A side positioning of direction (200) is filled, and the withholding tightening member (31) of second longitudinal direction component (1') is similarly oriented in main assembling Direction (201) is the direction opposite with the assembling of first longitudinal direction component (1) in the case.

Equally, the withholding tightening member (31) of first end component (2), which is oriented, is conducive to assembly orientation (200), and second The withholding tightening member (31) of end pieces (2'), which is similarly oriented into, is conducive to assembly orientation (201), and therefore with first end On the opposite direction of the withholding tightening member (31) of component (2).

This be arranged such that with the tightening member (31) of its assembly orientation (200,201) parallel orientation more easily will be described Element (31) is fixed in slot (1c, 2c), and is once assembled, what the power that may be generated on one side was generated on opposite side Power in opposite direction counteracts or compensates for, so that assembly be made to be kept fixed.In addition, for the same reason, in order to make to fasten Element (31) is easier to assemble, and each tightening member (31) includes the extension of outer edge (31a), is configured to be received In the slot (1c, 2c) of longitudinal component (1,1') and end pieces (2,2').

In addition, bottom (3) have inner wall (42) consistent withholding face (32) with block (4), so that they are against each piece (4), to also prevent crate from scattering after assembling because the power for being parallel to bottom of crate may be acted on.Therefore, it indulges It is inclined-plane (1b, 2b) to the inferior horn of component (1,1') and end pieces (2,2'), so as to also against block (4).

Figures 5 and 6, which are shown specifically, allows the crate object of the invention stackable feature in a manner of extremely favourable.It is practical On, Fig. 5 describe be similar to Fig. 1 to 4 described in crate two crates, vertical stacking so that crate load It directly and is only only delivered to form four blocks (4) at crate angle.This is a sizable advantage, because it prevents crate Side (1,1', 2,2') or bottom (3) bear load when crate stacks.In fact, the upper and lower surfaces of block (4) are distinguished It including top bar (45) complimentary to one another and gets out of a predicament or an embarrassing situation (46) (referring to Fig. 6), and wherein its outer surface is inclined such that more easily Stack crate.In addition, the height of block (4) make bottom (3) and each side (1,1', 2,2') be impossible to against which side or The crate of lower section contacts, therefore load is only transmitted to ground by the block (4) as column, thus prevents wall from bearing assembling The load of part.

Finally, due to the crate described, according to selection for assembling block (4) and longitudinal component (1,1') and end pieces A possibility that solution of (2,2'), this assembling provides assembly and disassembly assembly easily.
