Description

Hinge arrangement between two wall parts that are pivotable relative to one another, in particular of a crate-like transport container The invention relates to a hinge arrangement between two wall parts that are pivotable relative to one another, in particular of a crate-like transport container, as described in the preamble of claim 1.

In a known container according to DE 93 08 051.4 U the end and side wall parts are hinged by rocker pivot arrangements to the base part, and in their assembled position are secured by detachable locking elements to form a container. By means of the rocker pivot arrangements after unfastening the locking element the side wall parts and/or end wall parts can be pivoted outwards into a position level with the base, which means that for transportation when empty the container occupies a small amount of volume.

The disadvantage in this case is that the container in this state takes up a relatively large amount of floor space and thereby transport pallets for returning empty containers occupy an inappropriate amount of space. In "another known folding transport box according to EP d 443 327 A2 the side walls are connected to the base by pivot axes so that the side walls when o: 20 lying on top of one another can be pivoted inwards and parallel to the base.

or The disadvantage here is the expensive hinging of the side walls to the base and the unstable bearing, which means that the filling weight for such a transport container is reduced.

0* 25 The objective of the invention is to design a hinge arrangement of a transport container, which can resist high loads and permits an optional pivoting of longitudinal and/or transverse side walls into a position that is flush or parallel with the base.

According to the invention, there is provided a hinge arrangement between two wall parts of a crate-like container that are pivotable relative to one another about at least one pivot axis, the hinge arrangement comprising at least one hinge with at least one degree of freedom formed by a pivot pin and a pivot pin mount or by a film hinge, and the pivot axis is parallel to one side edge of one wall part, so that a first wall part can be moved relative to a second wall part between a perpendicular position and a position level or 2 flush with the second wall part, characterised in that the hinge arrangement comprises two hinges with at least one degree of freedom, which are arranged spaced apart from one another by a hinge body and the pivot axes are arranged parallel to one another, so that the first wall part can be moved into a position abutting at least one of an inner surface and an enveloping surface of the second wall part, and at least one of the first wall part and the hinge body is arranged in a position bearing against the second wall part, with the other perpendicular thereto within an end surface extending from the inner surface in the direction of the enveloping surface of the second wall part, and the pivot axes of the hinges are arranged between the inner and enveloping surfaces of the wall parts.

:s The surprising advantage is that, by means of the design of a hinge body with two hinges with at least one degree of freedom respectively, in addition to 15 the flat position, an optional pivoting into a parallel position of the wall parts relative to one another is also possible, in which the latter fit on top of one another either with their inner surfaces or even with their outer surfaces, in particular, enveloping surfaces.

S 20 A design according to claim 2 is also advantageous, by means of which a simple replacement of the wall parts and/or hinge bodies and also an easy assembly of a transport container designed in this way is achieved. 5 A design according to claim 3 is also possible, as thereby the number of individual parts needed for a transport container is reduced.

According to a preferred development as described in claim 4 a hinge arrangement able to bear high loads is achieved.

Designs according to claims 5 and 6 are also advantageous, in which a variable adjustment in the design of the elements for the transport container is achieved.

According to an advantageous development, as described in claim 7, a centring is achieved in the region of the hinge arrangement.

A development, as described in claim 8, permits an unlocking movement to unfasten the hinge arrangement.

According to the advantageous developments as described in claims 9 to 12, an optional pivotability between the wall parts or between the latter and the hinge body can be achieved.

An embodiment according to claim 13 is also possible, in which the unintentional detachment of the side wall parts from one another or from the hinge body is effectively prevented.

Preferred developments are also described in claims 14 and 15, in which despite the detachability of the hinge arrangement secure fastening against axial displacement is achieved.

A development according to claim 16 is also advantageous, by means of which a kind of locking device is achieved, which in a specific position opposes the pivoting of the wall parts.

9999 ooo 20 Lastly, a design according to claim 17 is also advantageous, as thereby the excessive loading of the hinge arrangement is effectively prevented.

0o 9 For a better understanding of the invention the latter is explained in more i detail with reference to the embodiments shown in the Figures.

Shown are: Fig. 1 a transport container according to the invention in schematic and perspective view; Fig. 2 the container in front elevation; Fig. 3 a portion of the container in cross section along the lines III-III of Fig. 2; Fig. 4 the hinge arrangement according to the invention in cross section along the lines IV-IV of Fig. 2; Fig. 5 the hinge arrangement according to the invention between the wall parts in cross section along the lines V-V of Fig. 2; Fig. 6 the hinge arrangement in cross section along the lines VI-VI of Fig. In Fig. 1 a container 1, in particular a crate-like transport container 2 is shown. The latter comprises a base 3, two opposite longitudinal side walls 4 and two opposite transverse side walls 5 at right angles to the latter, which form wall parts 6 that are pivotable relative to one another. The longitudinal side walls 4 and transverse side walls 5 comprise wall elements 7 with facing inner surfaces 8, which in an assembled position of the longitudinal side 15 walls 4 and transverse side walls 5 at right angles to the base 3 form an inner chamber 9 for holding various transported goods.

0* Parallel to the inner surface 8 is an outer surface 10 delimiting the wall 20 element 7 opposite the inner chamber 9. The wall element 7 is also bordered oo by an edge strip 11, which is connected in one piece with the latter and projects from the inner surface 8 in an opposite direction to the inner chamber 9 by an edge strip width 12 measured parallel to the base 3. Away from the inner surface 8 the edge strip 11 is delimited by an edge strip outer 25 surface 13. In the plane of the edge strip outer surface 13 which is spaced apart from the inner surface 8 by the edge strip width 12, is an enveloping surface 14 parallel to the inner surface 8, which delimits the transverse side walls 5 or longitudinal side walls 4 in an opposite direction to the inner chamber 9. Onto the outer surface 10 of the wall elements 7 webs 15 are formed preferably in one piece, forming a reinforcement, whereby the wall elements 7 have recesses 16 to reduce the weight of the transport container 2.

A recess 16 is in the form of a handle opening 17, which is delimited by a handle strip 18 formed on the wall element 7 projecting from the latter at right angles to the inner chamber 9.

At right angles to the inner surface 8 or to the outer surface 10 and to the base 3 are end surfaces 19 delimiting the longitudinal side walls 4 and/or the transverse side walls 5, to which centring and/or locking elements 20 are attached, in particular are moulded in one piece thereon. Centring and/or locking recesses 21 are assigned to the latter which are located in an imaginary overlap region 22, which is part of the inner surface 8 of the wall element 7 at right angles to the wall element 7 which comprises the centring and/or locking-elements 20. The overlap region 22 has an overlap width 23 which corresponds approximately to the edge strip width 12, and which is measured from an end side surface of the transverse side wall 5 and/or the longitudinal side wall 4 at right angles to the base 3 in the direction of the inner chamber 9. The edge strips 11, have preferably on longitudinal end surfaces 25 at right angles to the end surface 19 or end side surface 24 and parallel to the base 3, which delimit the edge strip 11 parallel to the base 3, 15 centring recesses 26, which particularly when stacking several transport 000S* containers 2 on transportation prevent the relative movement thereof.

Of course, it is also possible to arrange the centring and/or locking elements in the overlap region 22, whereby the latter would preferably be designed 20 in one piece with the wall element 7, and would project over the inner surface 8 opposite the enveloping surface 14 in the direction of the end .545 surface 19, for example the longitudinal side wall 4. The centring and/or r$0$ locking recesses 21 would be arranged in the end surface 19 in this variant.

25 The base 3 comprises a flat base plate 27, which also for weight reasons can comprises several recesses 16. The base plate 27 is delimited externally by a base edge strip 28, with an upper side 29 running parallel to the base plate 27 which also forms an inner surface 8, which projects over the base plate 27 by a shoulder height 30 measured perpendicular to the latter. The base edge strip 28 is delimited externally by a rotating side surface 31 opposite the inner chamber 9. The base 3 also comprises webs 15 aligned opposite the inner chamber 9, which are delimited by the enveloping surface 14 running parallel and opposite to the upper side 29 in opposite direction to the inner chamber 9.

In the following example two wall parts 6 are defined as a first wall part 32 and a second wall part 33.

The first wall part 32, for example, the transverse side wall 5 and the second wall part 33, for example, the base 3, are pivotable relative to one another about at least one pivot axis 34, which is parallel to the base 3 and to the inner surface 8. The pivot axis 34 can in the present embodiment be present both in the longitudinal side walls 4 and the transverse side walls However, it is also possible to secure, for example, the transverse side walls rigidly to the base 3 and to design only the longitudinal side walls 4 to pivot about the pivot axis 34 relative to one another and to the base 3.

Between two wall parts 6 of the transport container 2 that are pivotable 00 relative to one another about at least a pivot axis 34 a hinge arrangement i' 15 is arranged. The hinge arrangement 35 comprises at least one hinge 38 with at least one degree of freedom in the form, for example, of a pivot pin 36 and a pivot pin mount 37 or a film hinge. The pivot axis 34 runs parallel to a side edge 39 of a wall part 6 formed, for example, by the longitudinal end surface 25 and the edge strip outer surface 13. In this way the first wall part 32 is 20 adjustable relative to the second wall part 33 into a position that is perpendicular and flush or aligned with the second wall part 33 and vice 0. versa. The hinge arrangement 35 comprises two hinges 38 each with at least one degree of freedom, which are arranged spaced apart from one another by a hinge body 40, whereby the pivot axes 34 of the two hinges 38 are arranged 25 parallel to one another. In this way the first wall part 32 is adjustable into a position bearing on the inner surface 8 and/or the enveloping surface 14 of the second wall part 33.

The first wall part 32 and/or the hinge body 40 are arranged in a position bearing on the second wall part 33 and/or perpendicular thereto inside the rotating end surface 31 running from the inner surface 8 in the direction of the enveloping surface 14 of the second wall part 33. The pivot axes 34 of the hinges 38 are arranged between the inner surfaces 8 and the enveloping surfaces 14 of the wall parts 6, i.e. the base 3 of the longitudinal side walls 4 and the transverse side walls 5. The pivot axis 34 runs in the centre of the ~pivot pin 36 and the pivot pin mount 37.

The hinges 38 spaced apart from one another by the hinge body 40 or their parallel arranged pivot axes 34 are spaced apart from one another by an axial distance 41 measured at right angles to the base 3.

In this way it is achieved that the first wall part 32 is pivoted by a total angle of 2700 from a position at right angles to the base 3 into a position parallel thereto. If the wall height 42 of a wall part, for example, the longitudinal side wall, measured at right angles to the base 3, is not greater than half an inside width 43 which spaces apart two facing inner surfaces 8 and/or, for example, also two facing inner sides 44 of the base edge strip 28, the wall parts 6, i.e.

the two longitudinal side walls 4 can be pivoted into a position parallel to the base 3 and level with one another in the direction of the inner chamber 9.

The transverse side walls 5 can also be pivoted via pivot axes 34 relative to 15 the base 3. It is possible to pivot the hinge body 40 by 1800 from a position facing the inner chamber 9 at right angles to the base 3 into a position "opposite the inner chamber 9 at right angles to the base 3. The wall parts 6, i.e. the transverse side walls 5 can then be pivoted by an angle of 900 to the hinge body 40 from a position at right angles to the base 3 projecting over the latter in opposite direction to the inner chamber 10, into a position parallel to the base 3.

The transport container 2 can thus be configured in the state of empty transport or return transport, so that the longitudinal side walls 4 are folded in the direction of the base 3, i.e. resting on the inner surface 8 or upper side S"29 and the transverse side walls 5 are pivoted outwards and rest on the webs running opposite the inner surface 8 or upper side 29 or on the enveloping surface 14 delimiting the latter opposite the inner chamber 9.

In Fig. 2 a front view of the container 1, i.e. the transport container 2 is shown. The longitudinal side wall 4 has a length 45 measured parallel to the base 3 which spaces the end surfaces 19 apart from one another. The base 3 has a base length 46 which is greater than the length 45 and which spaces apart the side surfaces 31 from one another. A lower side 47 parallel to the longitudinal end surface 25 of the wall part 6, for example opposite the longitudinal side wall 4 is spaced apart from the upper side 29 of the base edge strip 28 by a height which is greater than a wall height 48 of the hinge body 40 measured parallel thereto. Along the length 45, which for example also delimits the hinge body 40 several hinge arrangements 35 are arranged.

The pivot pins 36 are connected by webs 49 to the edge strips 11 of the wall part 6 and the hinge body 40. The webs 49 have a web length 50 measured parallel to the length 44, which in both directions are projected over by the pin extensions 51 of the pivot pin 36 by an extension length 52.

The webs 49 of the hinge arrangements 35 are moulded in one piece on the edge strip 11 of the wall part 6. The webs 49 of the hinge arrangements arranged between the base 3 and the hinge body 40 are formed on the edge strip 11 of the hinge body 40. The edge strip 11 of the hinge body 40 has on the side facing the wall part 6 preferably two centring elements 53 spaced apart in the direction of the length 44, which on the stacking of demounted transport containers 2 should prevent a relative movement, preferably during the transportation of the transport containers 2. On the side of the edge strip 11 of the hinge body 40 facing the base 3 there are two openings 54 spaced apart in the direction of the length 45, which project over an underside 55 of the edge strip 11 of the hinge body 40 facing the base 3 in the direction of the wall part 6 by an opening depth 56.

9 The opening 54 forms, together with a pin 57 which. projects on a lower side 58 of the base edge strip 28 opposite the upper side 29 of the base edge strip 25 28 in opposite direction to the hinge body 40 by a pin height 59 measured perpendicular to the base 3, a stop device 60, which functions in that as a base surface 61 of the opening 54, which is spaced apart from the underside of the base edge strip 28 by the opening depth 56, which on pivoting the hinge body 40 by preferably 180' touches a stop surface 62 spaced apart from the underside 58 by the pin height 59 and prevents a further pivoting of the hinge body 40 by a pivot angle of 1800.

In Fig. 3 a portion of the transport container 2 is shown in cross section, in which a centring element 53 is better illustrated. The latter comprises a support element 63 preferably formed in one piece on the longitudinal end surface 25 of the edge strip 11 of the hinge body 40, which support element comprises a support web 64 projecting over the longitudinal end surface opposite the base 3 and a base web 65 running at right angles thereto and parallel to the longitudinal end surface 25. On the surface of the base web the base 3 a centring pin 66 is formed preferably in one piece, which in an end region 67 opposite the base 3 is approximately semi-circular.

The base web 65 is also connected with the edge strip 11 by transverse webs 68 at right angles to the support web 64.

As also shown in this Figure the base edge strip 28 is designed in an end region opposite the inner chamber 9 to be roughly semi-circular. The base 3 also comprises on a base underside 69 opposite the upper side 29 of the base edge strip 28 one or more base webs 70 forming webs 15, which support the base underside 69 in opposite direction to the inner chamber 9 by a web height 71. On the side of the base webs 70 forming the webs 15 opposite the 15 base plate 27 runs the enveloping surface 14 arranged parallel to the base plate 27, which delimits the webs 15 or the base webs 70 in opposite direction to the inner chamber 9 and thereby the base 3.

o* In the further described Fig. 4 an additional portion of the transport container 2 is shown in cross section, whereby in particular the hinge arrangements between the wall part 6 and the hinge body 40 or the latter and the base 3 are shown. The pivot pins 36 have a diameter 72 and are, as already described, connected via webs 49. to the edge strips 11. The webs 49 have inner surfaces 74 perpendicular to the edge strip 11 and closer the inner chamber 25 9 and inclined surfaces 74 at an angle to the edge strips 11 and from the •inner chamber 9.

The hinge arrangement 35 arranged between the wall part 6 and the hinge body 40, in particular its pivot pin 36, as already described, comprise the pivot axes 34 in their centres which are spaced apart by the edge strip 11 of the wall part 6 by a distance 75 in the direction of the base 3. The latter is selected so that it is slightly greater than a distance 76, from the pivot axis 34 to the longitudinal end surface 25 of the edge strip 11 of the hinge body Said longitudinal end surface 25 has in a region facing the inner chamber 9 a circular curved surface 77. The latter is projected over in the direction of the inner chamber 9 by a cam 78, which has a cam outer surface 79, which is spaced apart from the pivot axis 34 by a cam distance The latter corresponds approximately to the distance 75 and is greater than the spacing 76, whereby an automatic pivoting of the wall part 6 in the direction of the base 3 is prevented. Such pivoting is only possible if the cam 78 is elastically deformed so that the cam distance 80 corresponds to the distance 75, which can be achieved by additional force on the wall part 6 in the direction of the inner chamber 9. The pivot pin 36 is located in the pivot pin mount 37, which forms a bearing bush for the pivot pin 36.

With the hinge arrangement 35 arranged between the base 3 and the hinge body 40 the function is similar to that of the already described hinge arrangement 35. The pivot axis 34 of said hinge arrangement 35 is also 15 spaced apart by distance 75 from the lower side 55 of the edge strip 11 of the hinge body 40, which is opposite the longitudinal end surface 25. The latter is greater than the distance 76 which is measured from the pivot axis 34 to the upper side 29 of the base edge strip 28. In this way a pivoting of the hinge body 40 by 180' is ensured, whereby in the pivoted position the underside abuts the underside 58 of the base edge strip 28. The pivot pin 36 is also located in a bearing bush arranged in the base edge strip 28, which however completely delimits the pivot pin 36 in the region of the pin extensions 51 described in Fig. 2.

S• 25 In Figs. 5 and 6 the hinge arrangement 35 between the wall parts 32, 33 is :shown, for example between the wall part 6 and the base 3. In these drawings the wall part 6 is shown in a position level with the base 3 by solid lines and in a position at an angle of 900 to the base by dashed lines. The base 3 has a groove 81 running parallel to the surrounding side surface 31 on an outer surface 10 opposite the inner surface 8. A groove base 82 facing the inner surface 8 is designed to be semi-circular, whereby the depth 83 of the groove 81 is greater than the width 84. A longitudinal middle axis 85parallel to the side surface 31 and the inner surface 8, which at the same time forms the pivot axis 34 of the hinge arrangement 35, lies approximately midway along a dimension 86 of the base 3. The side surface 31 is rounded circularly in a direction perpendicular to its longitudinal extension, whereby a radius 87 from the longitudinal middle axis 85 corresponds to the distance 88 between the inner surface 8 of the base 3 and the longitudinal middle axis Concentrically to the longitudinal middle axis 85 the pivot pin 36 extending in the direction of the longitudinal middle axis 85 is arranged in the groove 81, which pivot pin is connected movably via the web 49 with the wall part 6 or a side surface 89 facing the base 3 of an edge strip 90 delimiting the wall part 6 in the direction of the base 3. A distance 91 between the side surface 89 and the longitudinal middle axis 85 corresponds approximately to the radius 87 of the circular side surface 31. In the region of the hinge body 40 an edge strip 92 accommodating the groove 81 is provided with a recess 93 for mounting the hinge body 40, which recess extends from the side surface 31 by distance 91, in addition to half the thickness of the hinge body 40 in the direction of the region of the base 3 assigned to the inner chamber 9. In the direction of its longitudinal extension the pivot pin 36 has a length 94, which 15 corresponds approximately to twice the width 95 of the web 49. In this way 9end regions 96, 97 of the pivot pin 36 projecting over the hinge body 40 are formed via which the wall part 6 is mounted pivotably in the groove 81. Here the groove 81 in one of the end regions 96, 97, as shown in the end region 96, in the direction of the outer surface 10 is closed by a retaining shoulder 98, whereby a mounting chamber 99 is formed for the end region 96 of the pivot pin 36.

oo 0$0 i.

To an end surface 100 of the pivot pin 36 arranged opposite the storage chamber 99 a locking element 101 delimiting the groove 81 in its longitudinal 25 extension is assigned, which is formed on the base 3 and extends from the inner surface 8 to the region of the longitudinal middle axis 85 and forms a stop surface 102 facing the front surface 100, which limits an axial displacement of the pivot pin 36. Opposite the base 3 the locking element 101 is designed to be elastically deformable by a weakened region formed by slots 103 in a vertical direction as shown by arrow 104. In connection with a conical stop 105 an insertion of the hinge arrangement 35 is permitted by inserting the pivot pin 36 into the groove 81 and the storage chamber 99. By pivoting the locking element 101 out of its locked position for the pivot pin 36 in the direction of the inner surface 8 an axial displacement of the pivot pin 36 in the direction of an arrow 106 in a separated position of the wall part 6 is permitted in which the web 49 is located outside end surfaces 107 centring the latter on both sides of its longitudinal extension. In this way it is possible to detach the wall part 6 from the base 3.

According to a preferred design the transport container according to the invention is made in particular of plastic. However other versions e.g. wood, metal etc. are also possible.

For a better understanding of the invention the elements of the invention are not always illustrated to scale in the individual Figures.

.0 Lastly, it is pointed out that individual combinations described in the individual embodiments, in particular those characterised in the subclaims, can be combined as desired, and individual characteristics can form independent separate designs according to the invention.
