Description

Storage box for small parts

Technical Field

The invention relates to a compartment for small parts, in particular screws, having a bottom and at least two side walls which originate from the bottom and are opposite one another, wherein the bottom and/or the side walls have at least one supporting flange (autoflash) for stacking a plurality of compartments of the same type, wherein, in the stacked state of the two compartments, a lower end region of a first side wall of an upper compartment is arranged parallel to an upper end region of a first side wall of a lower compartment, and a lower end region of a second side wall of the upper compartment is arranged parallel to an upper end region of a second side wall of the lower compartment.

Background

The invention should be utilized to improve the compartment for small parts, in particular with regard to its stackability.

Disclosure of Invention

According to the invention, a storage box for small parts, in particular screws, is provided for this purpose, which has a bottom and at least two side walls which originate from the bottom and are opposite one another, wherein the bottom and/or the side walls have at least one support flange for stacking a plurality of storage bins of the same type, wherein, in the stacked state of the two storage boxes, the lower end region of the first side wall of the upper storage box is arranged parallel to the upper end region of the first side wall of the lower storage box, and the lower end region of the second side wall of the upper compartment is arranged parallel to the upper end region of the second side wall of the lower compartment, wherein at least one locking element (Riegel) is arranged on at least one of the side walls, the locking element is movable between a release position and a locking position, and in the locking position the locking element secures the two storage containers stacked on top of each other to each other and releases them in the release position.

By means of such a locking element, two or more bins stacked on top of each other can be fixed to each other in a stacked state. This is a significant simplification, especially for transporting such bins. Since the compartment according to the invention is manufactured in different sizes and the just small compartments can obviously be stacked in the loaded state, such stacking quickly becomes unstable due to the small base of the compartments, especially when the compartments are loaded with heavy small parts, such as screws. However, even in large storage containers, the locking element provided according to the invention ensures a stable construction of a stack (stabel) of a plurality of storage containers. Such a stack can then be transported without problems without having to worry about the stacked storage boxes coming loose from each other. In particular, an additional separate transport fixture can be dispensed with. This is a significant advantage, for example, especially when the bin according to the invention is arranged in a vehicle comprising e.g. mobile service shop equipment. By being able to fix the compartments to one another in the stacked state, additional fixing measures can be dispensed with if necessary.

In one refinement of the invention, the locking element engages (hingergreifen) from behind an undercut (Hinterschnitt) on a lower end region of one of the side walls or in an upper end region of one of the side walls in the locking position and releases the undercut in the release position.

In this way, a very stable connection of the two stacked storage compartments can be achieved by means of a simple movement of the locking element, which may be embodied, for example, as a rotational movement or as a displacement movement.

In a development of the invention, the undercut is formed by means of at least one projection arranged parallel to the base.

The undercut may be formed in the base wall (sockelwan) or in the side wall by one or more protrusions or slits projecting parallel to the bottom. The locking element is then moved (e.g., pushed) over the one or more projections and thereby locks the projections. Hereby, a stable fixing of the two storage compartments to each other can be achieved with a very short movement of the locking element. In the locked state, the connection is form-locking and thus extremely stable. The locking element can also surround the (umgreifen) projection and be designed as a moving locking element or as a rotating locking element, for example.

In a development of the invention, the locking element is designed to move the locking element and is arranged movably by means of the slotted guide in the upper end region of the first and/or second side wall or in the lower end region of the first and/or second side wall.

The slotted guide in the side wall can also be produced in a complex shape, particularly when the storage compartment is produced by injection molding of plastic. The moving latch can be fixed in such a sliding slot guide in a very stable manner. Advantageously, the mobile locking element itself is also produced by means of plastic injection molding.

In a development of the invention, the gate guide is formed by means of at least one slot in the first and/or second side wall and by means of at least one undercut projection on the sliding closure.

In this way, easy mobility and at the same time simple manufacturability can be achieved.

In a development of the invention, the undercut projection on the sliding closure is designed as a detent element.

For example, the mobile locking element can be snapped or clipped into a slotted guide of the sliding groove. In this case, one or more detent elements on the mobile locking element can be designed in such a way that a non-destructive removal of the mobile locking element is no longer possible. Thereby, manipulation of the filled and for example locked compartment may be prevented.

In a development of the invention, the first side wall has a first base wall extending below the bottom and the second side wall has a second base wall extending below the bottom, and the first and second base walls are provided with projections parallel to the bottom and projecting outwards from the interior space of the compartment, which projections form undercuts, and a locking element is provided in each case in the area of the upper ends of the first and second side walls in order to engage them from behind.

In this way, two locking elements, which are preferably designed as moving locking elements, can be arranged in good proximity on the upper end and on the outside of the respective side wall. In this case, the first and second base walls are located on the inner side of the first or second side wall, respectively, in the stacked state of the bin. The projection and the locking element acting thereon in the locking position can thus be arranged such that the element causing the locking is located protectively and manipulation-proof on the inside of the side wall and only one operating element of the locking element is located in good access on the outside of the side wall.

In a development of the invention, the locking element locks the lid of the compartment in the locked position.

By this dual function of the locking element, the contents of the compartment can be secured in a loss-proof manner by the locking lid. The cover of each compartment may thereby also be secured while two or more compartments are locked to each other in a stacked state. Thereby, the safety when transporting the compartment according to the invention is further improved.

In a development of the invention, the locking element has a first and a second locking position, wherein in the first locking position the cover of the compartment is lockable and in the second locking position not only the cover is lockable but also the two stacked compartments can be locked to each other.

In this way, for example two storage boxes stacked on top of each other can be separated from each other without having to release the cover of the storage box. This also significantly increases the safety during transport and in particular during the separation and stacking of several storage boxes.

In a further development of the invention, a sealing plug is provided which can be plugged through the locking element and limits or prevents a movement of the locking element.

By means of such a seal, a plurality of storage containers can be secured against manipulation to one another in the stacked state. First, however, unauthorized opening of the lid of the compartment may also be prevented.

The sealing plug advantageously has a predetermined breaking point and can only be released by breaking the sealing plug after insertion into the locking element.

In this way it is immediately recognizable whether the compartment has been opened and widgets may be unauthorized lost.

In a development of the invention, the sealing plug can be inserted into the cover through the closure.

In this way, a structurally simple, stable and manipulation-proof arrangement of the sealing plug is possible.

In a development of the invention, the locking element can only be moved between the first and the second locking position when the sealing plug is inserted.

It is thereby possible, when the sealing plug is inserted, to stack a plurality of storage boxes on one another and then to fix them to one another in the stacked state. However, it is not possible to open the lid without removing the sealing plug. For this purpose, the sealing plug and the locking element must be designed such that the sealing plug locks the release position for the cover, but a locking position for the stacked containers and also a release of this locking can be achieved.

In one development of the invention, a cover for the storage compartment is provided, wherein the cover is arranged in the closed state below an imaginary plane defined by the upper edges of the side walls, and wherein the cover has at least one grip projection (griffvorrsprung) extending in the direction of the imaginary plane.

By arranging the lid in the closed state below an imaginary plane defined by the upper edges of the side walls, the containers can be stacked and, if necessary, coupled, independently of whether the lid is placed or not. The handle projection of the lid facilitates the handling of the lid and also of the compartment in the closed state.

In a development of the invention, the bottom of the compartment has a groove or a stop extending in the longitudinal direction of the compartment for forming a groove-like receptacle extending in the longitudinal direction of the compartment.

Such grooves or trough-like receptacles extending in the longitudinal direction of the compartment can be used, on the one hand, for arranging retaining strips wound around the compartment or also for guiding the compartment longitudinally by means of projections on the bottom (Regalfachboden) of the compartment. When the retaining strip is arranged in a trough or trough-like receptacle, it is very advantageous here that the retaining strip does not protrude beyond the bottom contour and thus does not hinder the stacking of a plurality of storage boxes.

In a further development of the invention, a cover for the compartment is provided, wherein the cover is provided with a further groove or stop extending in the longitudinal direction of the compartment for forming a further groove-like receptacle extending in the longitudinal direction of the compartment.

Such a further groove or a further groove-like receptacle on the cover is likewise used for the arrangement of the retaining band. The retaining strap then presses the cover against its support on the compartment. By arranging the retaining band in the slot, the retaining band does not interfere when stacking a plurality of containers. Advantageously, the further slot is arranged in the handle of the lid and has a shape curved in the longitudinal direction. This makes it possible to apply a uniform and high pressure to the cover by means of the holding strap.

Detailed Description

The illustration of fig. 1 shows a compartment 10 according to the invention according to a preferred embodiment.

The compartment 10 has a base 12 with a bottom, which is not visible in fig. 1, a first side wall 14 and a second side wall 16 opposite the first side wall 14, and a rear wall 18 arranged perpendicular to the two

side walls

14, 16. The

side walls

14, 16 and the rear wall 18 together form a substantially U-shaped support flange 20 which delimits the upper edge of the

side walls

14, 16, 18 and on which the other storage compartment rests in the stacked state.

The position of the bottom of the bin 10 is only visible in the illustration of fig. 1 by means of the bottom flange 22, which extends outwardly from the first side wall 14 and is at the same height as the bottom, which is not visible. Below the bottom, the side wall 14 has a first base wall 24.

Opposite the rear wall 18, a front wall 28 is provided which, however, extends from the bottom only up to about half the height of the interior space of the compartment 10. The front wall 28 is also not perpendicular to the bottom, but is arranged at an angle of less than 90 ° to the bottom and extends obliquely inwardly and upwardly therefrom in fig. 1. Typically, a text area (Schriftfeld) is arranged on the front wall 28, which text area contains the name of the small parts in the bin 10. This text area can thus be read very well by the inclined arrangement of the fourth side wall 28.

In the region 30 of the front wall 28, a slide (Schieber) is provided, which can be moved between two positions, which are only schematically illustrated in fig. 1. By means of such a slider, for example, different color markings can be released or covered, which color markings then indicate, for example, whether the compartment 10 is empty, whether a small part in the compartment 10 has been filled (nachbestellen), or also other features.

A window 32 in the form of a transparent plastic cover extends from the upper end of the fourth side wall 28 to the upper edge of the

side walls

14, 16. The window 32 allows the interior space to be viewed in the closed state of the compartment 10 shown in fig. 1. The window 32 may be flipped downward at approximately 180 from the position shown in fig. 1 enclosing the interior space until the window is substantially parallel to the front wall 28. In this flipped down state, the operator can then reach into the compartment 10 and remove the small parts.

The compartment 10 is further provided with a lid 34 which in fig. 1 closes off the inner space of the compartment 10. In this case, the cover 34 is arranged below the upper edges of the

side walls

14, 16 and the rear wall 18 and thus also below the bearing flange 20. Thereby, even when the cover 34 is inserted, the plurality of the storage boxes 10 can be stacked on each other without any problem.

In the upper region of the

side walls

14, 16 lying opposite one another, a

movement closure

36, 38 is arranged in each case. The moving latches 36, 38 are movable between a release position shown in fig. 1 and a locking position, not shown, respectively. In the release position, a plurality of the bin 10 may be stacked on one another and may also be lifted from one another again. In the release position shown in fig. 1, the cover 34 may also be removed. Starting from the release position shown in fig. 1, the moving latch 36 can be moved forward, in the direction of the front wall 28. In this locking position, the moving of the locking

members

36, 38 locks the other compartment, not shown in fig. 1, stacked on the compartment 10, so that the two compartments can then no longer be separated from each other. Furthermore, moving the

latches

36, 38 locks the lid 34 in the locked position such that the lid 34 can therefore no longer be removed from the bin 10.

In order to lock the cover 34 in the rest position shown in fig. 1, the mobile locking element 38 locks a catch 40 provided in the upper region of the second side wall 16. The hook 40 is resiliently connected to the second wall 16. The moving latch 38 rests in the locked position on the rear side of the catch 40, which is covered in fig. 1, and thus prevents the catch from being able to shift obliquely to the upper left in fig. 1, i.e. away from the cover 34. This will be discussed in more detail below. In the locked position, the movement latch 36 likewise latches a latching hook, not visible in fig. 1, in the upper region of the first side wall 14. In the shown release position of the moving latches 36, 38, the catch 40 can be deflected laterally and thereby release the lid 34 when an attempt is made to lift the lid 34.

Only three locking projections 42 of the sliding latch 38 are visible in the illustration in fig. 1, which project through slot-like slotted guide sections 44 in the upper region of the second side wall 16. All three slot-like slotted link guides 44 are of identical design and are arranged at the same height in the upper region of the second side wall 16. The three locking projections 42 are also configured identically to each other. In order to fix two storage boxes 10 stacked on one another to one another, the locking projections 42 are moved, starting from the position shown in fig. 1, onto the respective left end of the chute guide 44. In this moved state, they are then arranged above the projections 50 extending outwardly from the base wall of the other compartment. Such a projection 50 is visible in fig. 1 on the lower end of the first base wall 24.

It can also be seen in fig. 1 that the cover 34 has recesses 52 on its edges, which are each configured to mate with a locking projection 42. In the release position of the moving latches 36, 38, the lid can thus be lifted upwards over the locking projections 42.

On the moving latch 36, the through-opening 54 can be seen in the front region arranged on the left in fig. 1. The through-opening 54 is provided for the insertion of a sealing plug, not shown in fig. 1. The sealing plug then penetrates the mobile closure 36 and the first side wall 14 at the through-opening 56 provided in the side wall 14 and is then inserted into a matching recess in the cover 34. The sealing plug, which is also explained below with reference to fig. 6, can thus not only lock the mobile locking element 36 in its locking position, but at the same time also fix the cover 34 in the closed position.

In the region of the rear wall 18, a hook-shaped formation 58 can be seen in fig. 1. By means of such a hook-shaped construction 58, the compartment 10 can be suspended to a matching retaining rail, which is arranged, for example, on a work bench. The compartment 10 can thus be arranged in a simple manner and very close to it, for example above a work surface of a work bench.

The illustration of fig. 2 shows the compartment 10 of fig. 1 in a diagonally rearward view, so that in fig. 2 the rear wall 18 is seen with a hook-shaped structure 58, in which view the first base wall 24 can be seen on the first side wall 14 below the bottom flange 22, the base wall 24 has a total of three outwardly directed projections 50 projecting from the interior space of the compartment 10, these projections 50 each form an undercut and are provided for being engaged from behind by the locking projection 42 of the moving latch in the locked position, as already explained, the locking projection 42 can be seen on the moving latch 38 in fig. 2, if in fig. 2 the compartment 10 is arranged on another compartment of the same type, the result is that the left moving latch of this other compartment has to be moved forward in fig. 2 into the plane of the drawing of fig. 2, so that the locking projection 42 will be arranged above the projection 50 of the base wall 24 in order thereby to fix the compartment 10 on the lower compartment, the slide projection (3521) can be provided for facilitating the pushing of the locking projection from behind by the slide projection (3521).

In fig. 2, essentially a first groove 60 on the bottom of the compartment 10 is visible, which extends in the transverse direction. The first slot 60 is used to incline the bin 10, for example, when a protrusion on the front end of the shelf bottom of the shelf is inserted into the first slot 60. In this case, the compartment 10 is tilted about the projection or slot 60 until the support flange 20 abuts the underside of the bottom of the upper compartment, at least in the region of the third side wall 18.

On the bottom of the compartment 10a second groove 62 is visible, extending in the longitudinal direction of the compartment 10. The second grooves 62 are provided on the one hand for ensuring, in cooperation with the projections on the shelf base of the shelf, a lateral guidance of the compartment 10 during insertion into the shelf and during withdrawal from the shelf. Furthermore, the second slot 62 is provided for arranging a partially shown retaining strap 64, which is wrapped around the compartment 10 in order to fix the cover 34 in its position on the compartment 10. Thereby, the retaining strap 64 extends above the lower end of the bin 10 and thus does not interfere with the stacking of the plurality of bins 10.

A U-shaped recess 66 is provided in the upper side of the rear side wall 18, which is likewise provided for the arrangement of the retaining strap 64. Thereby, the retaining strip 64 is fixed in the lateral direction and then does not protrude beyond the support flange 20 so as not to interfere with the stacking of the plurality of bins 10.

The cover 34 is provided with a handle 68 in the form of a protrusion that is strip-shaped and extends in the longitudinal direction. The handle 68 is provided on its upper side with a third groove 70 which extends parallel to the longitudinal direction and in which the retaining strip 64 can be arranged. As can be seen from fig. 2, the upper side of the handle 68 and thus the base of the groove 70 extend slightly curved as seen in the longitudinal direction. Thus, the highest point of the base of the trough 70 is located in the middle of the compartment 10, seen in the longitudinal direction. The holding strap 64 can thus exert a uniform pressure on the cover 34 and can thus also bear against the base of the groove 70 over the entire surface.

The window 32 on the front side of the bin 10 is centrally provided with a U-shaped notch 72 that is aligned with the slot 70 and notch 66 in the rear side wall 18. Thereby, the retaining strip 64 can be wound around the compartment 10 and, on the one hand, in the

recesses

66, 72 and in the groove 70 and in the recess 62 in a slip-proof manner in the lateral direction. At the same time, the storage boxes 10 can also be stacked without problems with the retaining strips.

The illustration of fig. 3 shows the compartment 10 of fig. 1 from obliquely below. The underside of the base 74, which is provided with a plurality of reinforcing ribs, is visible in this view. The first and

second slots

60, 62 are also clearly visible, the first slot 60 extending in the transverse direction of the bin 10 on the underside of the bottom 74 and the second slot 62 extending in the longitudinal direction on the underside of the bottom 74.

The bottom 74 laterally has two bottom flanges 22 which, in the stacked state of two storage boxes 10, rest on the upper side of the side walls of the lower storage box and thus on the support flanges 20 thereof. From the bottom flange 22 downwards, i.e. upwards in fig. 3, a first base wall 24 extends in the extension of the first side wall 14 and a second base wall 26 extends in the extension of the second side wall 16. The two

base walls

24, 26 are provided with three projections 50, respectively, which project outwardly from the

respective base wall

24, 26 and which, as already explained, are provided for co-action with the locking projections 42 on the

movable locking members

36, 38 of the respective lower compartment in the stacked state of the two compartments 10.

Fig. 4 shows the moving latch 38 of fig. 1 in a separated view from obliquely above, i.e. in a state of being removed from the compartment 10.

It is possible to see locking projections 42 which, as shown in fig. 1, are provided for guidance by slot-like slotted guide sections 44 of the side walls 16. The locking projections 42 each have a slot guide 78 between two guide projections. When the locking projection 42 is arranged in the slot-like gate guide 44 in the position shown in fig. 1, a section of the side wall 16 is arranged in this gate guide 78. Expediently, the guide projections, which are visible on the right in fig. 4, are provided with a slide-aid ramp, so that the sliding closure 38 can be pressed or snapped into the slot-like slotted guide 44 in the side wall 16. For this purpose, the slot-like gate guide 44 has an intermediate section with a greater height as shown in fig. 1, into which the locking projection 42 can then snap. For all chute guides, sections with a smaller height are arranged to the left and right of the middle section with the larger height. When the locking projection 42 is located in the section with the lower height, the moving latch is in the release position or locking position shown in fig. 1. In these sections of smaller height, it is no longer possible to remove the locking projection 42 from the slot-like gate guide 44 without damage or to also snap it into the gate guide 44.

In fig. 4, a groove (riffleng) 80 and symbols and arrows can also be seen on the side of the displacement closure 38 which is located on the outside in the installed state, in order to indicate the specific function, i.e. locking or release, and the displacement direction required for this.

The function of providing a through opening 54 for inserting a sealing plug has already been explained.

The illustration of FIG. 5 shows the moving latch 38 of FIG. 4 from an oblique rear. In this view, the locking projection 82 can be seen, which extends inwards in the same direction as the locking projection 42. The latching projections 82 are provided for latching the latching hooks 40 in the upper region of the two side walls from behind, see fig. 1. If the latching projections 82 are located behind the corresponding latching hooks 40, they can no longer be deflected backwards in the illustration of fig. 1 when an attempt is made to lift the cover 34 from the compartment 10. The latching projection 82 is located behind the catch 40 when the mobile latch 38 or the mobile latch 36 is in the latched position.

The sliding closure 38 is embodied as a plastic injection-molded part and has a large number of reinforcing ribs on its rear side facing the viewer in fig. 5.

Fig. 6 shows a sealing plug 84 for the compartment 10, see fig. 1, which is provided for insertion into the through opening 54 in the

movable locking element

36 or 38.

The sealing plug 84 has a latching projection 86 with two undercuts lying opposite one another. These undercuts are dimensioned such that the sealing plug 84 can be inserted into the opening 54 in the moving

latch

36, 38, but can only be inserted or pressed with great pressure into the opening 56 in the

side wall

14, 16. As soon as the latching projection is moved through the opening 56 in its widest part, the laterally formed latching projection springs back slightly (auffedern) again, so that the sealing plug 84 can no longer be pulled out of the opening 56 and the opening 54 without destroying the sealing plug 84. For this purpose, the latching projections 86 can also be provided with a predetermined breaking point 88 which is of a weaker design than in the illustration of fig. 6. The predetermined breaking point 88 is only schematically illustrated in fig. 6 by a dashed line. The two lateral undercuts can also be formed on the latching projections 86 in other ways, for example as resilient latching hooks.

In the inserted state, the sealing plug 84 engages through the opening 54 in the mobile locking element 36, through the opening 56 in the side wall 14 and then also through the recess in the cover 34. The notches are located on both lateral ends of a ridge 90 on the cover 34, see fig. 1. As a result, the mobile locking element 36 and, accordingly, the other sealing plug 84 can be used to lock the mobile locking element 38 in its locking position. It is then no longer possible to move the moving latches 36, 38 into the release position. At the same time, the sealing plug 84 projects a distance into the recess in the bead 90 on the cover 34 and thus ensures a further additional locking of the cover 34. On its side opposite the bulge 90, which side rests against the inner side of the third side wall 18, the cover is held in a hinged manner and cannot therefore be removed upward in the closed state of fig. 1. This is only possible if the lid 34 is flipped over a distance.

The illustration of fig. 7 shows two

storage boxes

10a, 10b stacked on top of each other, which are each constructed in the same way as the storage box 10 of fig. 1. In this view it can be clearly seen that the upper storage bin 10a rests with the lower side of its bottom flange 22 on the upper side of the support flange 20 of the lower storage bin 10b, which is arranged on the upper side of the

side walls

14, 16 of the lower storage bin 10 b.

Here, the

base walls

24, 26 of the upper storage box 10a extend only in the extension of the

side walls

14, 16 of the upper storage box 10a, respectively. While the front wall 28 of the upper bin 10a terminates at a bottom level. Thus, there is space available below the front wall 28 to catch the window 32 of the lower compartment 10b at its upper edge and, if necessary, to flip the window 32 downwards. Thereby, even in the stacked state of the two

storage boxes

10a, 10b, the window 32 may be engaged into the inner space of the lower storage box 10b by turning down.

The illustration of fig. 8 shows a cross-sectional view of two

stacked bins

10a, 10 b. Here too the bottom flange 22 of the upper compartment 10a and the supporting flange 20 of the lower compartment 10b can be seen.

Furthermore, it can be seen that the

base walls

24 and 26 extend a distance into the space formed between the upper regions of the

side walls

14, 16 of the lower bin 10 b. Even if the lower compartment 10b is provided with a lid 34 as shown in fig. 8, such a stacked arrangement of two

compartments

10a, 10b can be used. Because the lower edges of the

base walls

24, 26 are either still above the upper side of the cover 34 or above the upper side of the cover 34.

Fig. 9 shows an enlarged detail of the illustration of fig. 8, i.e. the region with the moving latch 38 shown on the left in fig. 8. As can be seen first in fig. 9, the base wall 26 is arranged in the stacked state of the two

storage boxes

10a, 10b in such a way that the underside of the projection 50 is located slightly above the upper side of the cover 34 of the lower storage box 10b or slightly above the upper side of the cover 34. Thus, the upper side of the protrusion 50 is disposed below the chute guide 44 in the side wall 16 of the lower storage box 10b on the left in fig. 9. The locking projection 42 on the moving latch 38, which extends through the slot-like gate guide 44 to the inside of the side wall 16, can thereby be pushed over the projection 50. The release position of the moving latch 38 is shown in the illustration of fig. 9. Therefore, in this state, the locking protrusion 42 is located behind the protrusion 50, so that the upper bin 10a can also be lifted upward. However, if, starting from the release position shown in fig. 9, the sliding closure 38 is moved forward, i.e. out of the plane of the drawing, the locking projection 42 comes into position above the projection 50. Thereby preventing upward movement of the protrusion 50 and thus also the upper compartment 10 a. The two

bins

10a, 10b are then secured to each other and may be transported as a unit.

The illustration in fig. 10 shows the detail shown on the right in fig. 8, i.e. in the region of the moving closure 36. It can also be seen in this figure that in the release position shown in fig. 10, the projection 50 of the base wall 24 extends outwards, but the displacement projection 42 of the displacement lock 36 is also arranged beside the projection 50. Only when the moving latch 36 has been moved out of the plane of the drawing forward in fig. 10 does the moving projection 42 come into position above the projection 50 of the base wall 24 and thereby prevent the upper compartment 10a from being able to be lifted from the lower compartment 10 b.

The diagram of fig. 11 shows an enlarged detail of fig. 1. It can be seen that a catch 40 is located in the upper region of the side wall 16 which retains the lid 34 in its closed position. The latching hook 40 is arranged in the side wall 16 in an elastic manner in that it is arranged inside a U-shaped recess 94 in the side wall 16. The latching hook 40 is therefore surrounded on three sides by the recess 94 and is thus connected to the remaining material of the side wall 16 only by the web-shaped section of the side wall 16. The latching hook 40 can thus be elastically deflected and deflected out of the plane of the side wall 16, that is to say in fig. 11, for example, outwardly into the plane of the drawing. This movement of the catch 40 is necessary when the lid 34 is placed on the compartment 10. The lateral edges 96 of the cover enter into the region of the slide-on ramps 98 of the latching hooks 40 during the placement of the cover. By means of this slide-on ramp 98, the latching hook 40 is deflected outward when the lid is pressed downward. As soon as the cover reaches the position shown in fig. 11, the latching hook 40 springs forward again and thus reaches a distance above the cover 34. The lid 34 is thereby retained on the compartment 10. However, the lid is provided with a sliding-aid bevel, see fig. 12, below the hooks 40, so that the lid can be lifted from the compartment 10 against a slight resistance, while the hooks 14 can still be sprung. Thus, the lid 34 does not automatically fall out of the bin 10 when transporting the bin 10 with the lid 34 placed.

To secure the lid 34 on the bin 10 such that the lid 34 can no longer be lifted without damage, the moving latch 38 is moved into its locked position. In the illustration of fig. 11, this would be a movement of the displacement projection 42 to the left in the slot-like gate guide 44.

Fig. 12 shows a sectional view of the compartment 10 in the area of the moving closure 38, wherein the section is through the hook 40 of the side wall 16. Fig. 12 shows the release state of the moving latch 38. A glide-assist ramp 100 on the cover 34 can be seen below the catch 40. It can be seen that in the state of fig. 12 the cover 34, when lifted, presses the latching hook 40 outwards via the slide-aid ramp 100 and can thus be lifted from the compartment 10.

If the moving latch 38 is moved into its locking position, i.e. pushed forward to the right in fig. 12, the latching projection 82 (see also fig. 5) is arranged directly behind the catch 40. If necessary, the latching projections 82 can also rest against the rear side of the latching hooks 40. If this position is reached, the catch 40 can no longer be deflected backwards when the cover 34 is lifted. The lid 34 is thereby securely held in the position shown in fig. 12 and placed onto the compartment 10.
