Definitions

  • the invention relates to a container for storing and transporting objects, the container possibly consisting of several individual levels which are detachably connected to one another so that the container can be expanded as desired.
  • the individual levels consist of tubs that are open at the top and can be accessed by completely or partially removing the tub above. By placing the overlying tub, the tub that is closed to the side and downwards is also closed to the top. After placing a lid or a non-filled tub on the top, filled tub, none of the objects stored in the container can fall out.
  • Such a container is shown, for example, by the German utility model G 72 44 356, with which the goods required in hospitals are to be stored and transported.
  • the next trough is placed vertically from above onto the trough underneath, with latching elements made of spring steel, which are riveted to the plastic troughs, latching into one another laterally on opposite outer walls of these troughs.
  • this container has a number of disadvantages: First, the individual tubs are very complicated from the tub itself and the parts of the locking devices attached to it.
  • a particular tub can only be made accessible by completely lifting and separating the tubs above it from the tub to be filled or emptied.
  • a partial opening for the purpose of accessibility which enables a single intermediate trough to be filled and emptied more quickly, cannot be achieved.
  • the child safety of this container also leaves something to be desired, since the latching devices on the two sides can be opened independently of one another and then the upper trough can be lifted off.
  • Another disadvantage is that only such objects can be placed in these tubs that are at most as high as the clear height of the individual tubs. Larger objects can only be placed in an uppermost tray of the container that is not closed from above and are therefore not protected against falling out.
  • the object of the present invention to avoid the disadvantages of the prior art and, in particular, to create a stackable container, the individual levels of which, despite the simple and integral design, can be opened for the purpose of accessibility without completely separating the individual elements.
  • the size of the Container interiors can be variably adapted to the objects to be stored with as few different container elements as possible.
  • the container can be opened in any desired level, for example to remove objects from this level.
  • both the levels above and the levels below remain closed and the two parts of the container, that is to say above and below the opening level, are nevertheless not completely separated from one another. This enables a much faster filling, emptying or repacking within the container, since opening and closing is faster. It also avoids the risk of losing layers that were completely separated during repackaging.
  • the locking devices in the vicinity of the front wall of the individual tubs ensure that after the container is closed, the individual levels are firmly connected to one another and cannot open themselves.
  • the individual trays can be completely separated from one another after opening without removing any separate connecting parts.
  • the insertion and receiving element can only be separated by a parallel displacement, which, however, is prevented by the interlocking locking elements and locking recesses of the adjacent troughs.
  • tubs in which this floor is missing in whole or in part and which therefore consist of only one frame there are spaces of variable height within the container, so that objects which are above the height of a single tub can be kept.
  • the insertion element of the hinge consists of a thickened extension which is somewhat due to the elasticity of the plastic material used springs and protrudes over the edge of a tub in the direction of the tub to be connected.
  • the extension should align with the outside of the tub on the outside and at the same time represents the extension of one side of a fireplace, which is integrated with this one side in the wall of the tub. In its outer surface, this extension has a recess running transversely to the longitudinal direction of the chimney and, as a result, has a cranked shape in its cross-sectional representation.
  • a receiving element of the next, similarly designed tub acts like a hinge together.
  • the receiving element is formed by an opening at the opposite end of the same, integrated into the wall of the tub, side of the chimney, which also runs transversely to the longitudinal direction of the chimney like the recess in the insertion element and is separated from the end of the wall of the tub by an edge strip. Both the opening and the edge strip are dimensioned such that it is suitable for receiving the free end of the cranked extension, the edge strip then coming to rest in the recess of the cranked extension.
  • the free cross-section of the chimney is only slightly larger than the cross-section of the extension to be accommodated, so that the projections striving from one trough could be introduced in the longitudinal direction of the chimney of the next trough, but only with an axis offset, but not when the Longitudinal axes of the two chimneys is possible.
  • Exactly this axial misalignment is, however, prevented by the likewise protruding locking elements and locking recesses, which can only be inserted into one another when they are aligned and have a longer axial extension than the insertion element.
  • two tubs connected by means of the hinge can first be unfolded without loosening the connection until latching elements and latching recesses are disengaged.
  • the two trays remain connected to each other, provided the upper tray on the hinge is not actively removed from the lower tray. If this does not happen, the upper trough only drops automatically when it is opened by approximately 90 ° due to the shift of the center of gravity of the upper trough over the rear edge of the lower trough.
  • the shape and mode of action of the locking device are closely related to the mode of action of the hinge.
  • the latching element which is to be partially received in a corresponding latching recess when it snaps into place, consists of a tongue which represents an extension of one side of a fireplace integrated with this side into the wall of the tub.
  • the outside of the tongue is flush with the outer surface of the wall of the tub, but is thicker than this wall.
  • the tongue has a recess running transversely to the longitudinal direction on the outside, which has a depth corresponding to the normal thickness of the wall of the tub.
  • the outside of the free end of the tongue is spherical to facilitate sliding in the direction of the recess of the next tub.
  • This recess consists in a recess on the same side of the fireplace - and thus the wall of the tub - which is extended by the tongue.
  • the locking recess is dimensioned so that it is suitable for receiving the free end of the tongue. A remains between the recess and the edge of the wall of the tub opposite the tongue Edge exist, which just comes to rest in the recess of the tongue when the locking element is in the locking recess.
  • the dimensioning of the locking device should be based on the angular position of the hinge as follows: First of all, the tongues should not have such a large axial length that, after the latching device has been disengaged, the angle between the two trays is already reached, at which the hinge already separates automatically. So that the tongue can be inserted into the chimney of the locking device of the next tub, the free cross section of this chimney must be larger than the cross section of the tongue. However, the tongue is not inserted axially in the direction of the longitudinal axis of the chimney, but is inserted into the chimney in an arcuate movement due to the pivoting of the moving trough around the hinge.
  • This game depends on the axial length of the tongue and the distance of the locking device from the hinge. However, the size of this game must not be so great that when two troughs are in parallel one above the other, the insertion element can thereby disengage from the receiving element, that is to say it lies completely within the free cross section of the receiving element. Because then would be by lifting the upper tub vertically Above a separation of the two trays is possible despite the parallel position, which is not desirable.
  • guide elements should be attached to the bottom and top edges of the tubs, which ensure that the walls of the tubs lie flush on top of one another over their entire length. As a result, the tightness between the individual levels and thus troughs is maintained even when one of the walls of a level bends.
  • an appropriately designed cover can be used instead of a further trough which takes on the closing function and is equipped with the same hinges and locking devices or their individual parts. This increases the loading height of the top trough by the inside height of this lid, so that this top level is particularly suitable for holding objects that are above average compared to the lower levels.
  • the container according to the invention also has a smooth outer contour, provided that the chimneys described are located on the inside of the walls of the tubs and the extensions and tongues described are aligned on the outside with the outer surfaces of the walls of the tubs.
  • a latching device is arranged on the opposite side walls, these must be arranged sufficiently far from the edge of the tubs opposite the hinge so that a child with his relatively short fingers does not simultaneously touch the side walls with the index or middle fingers of one hand Operate locking devices and at the same time with the thumb of the two hands on the front of the tub can swing it apart.
  • Fig. 1 shows a container, which consists of four stacked and interconnected tubs 2, of which the middle have no bottom, so that this creates a container interior which corresponds to approximately three times the height of a tub 2.
  • a cover 24 On the uppermost trough there is a cover 24, which in FIG. 1 is opened so far around the hinge 22 (not visible there) that the uppermost trough 2 is already accessible.
  • the latching devices 5 can be seen in the side walls 10 of the individual tubs 2 in the vicinity of the front wall 9, the tongues 17 of the tubs 2 below being located in the recesses 21 of the tubs 2 above in the lower three latching devices 5 engaged .
  • the edge 24 between the recess 21 and the lower edge of the side wall 10 of the tub can be seen in each tub. To this end, the tongues 17 of the latching devices 5 protrude beyond the upper edge of the side walls 10 of the containers 2.
  • open trough 2 is the cross at the transition between the tongue 17 and the side wall 10 Recess 20 extending to the longitudinal direction of the tongue 17, into which the edge 24 of the overlying trough or of the cover 24 comes to rest when the latching device 5 is closed.
  • the two chimneys 25 can also be seen, each of which is integrated into a side wall 10 of the tub 2.
  • the tongue 17 protrudes from this integrated side with its semicircular end.
  • FIG. 2 shows a top view of one of the troughs 2, with guide elements 26 being additionally arranged on the side walls 10.
  • FIG. 3 now shows a more precise cross-sectional illustration of a latching device 5, cut along the line A-B of FIG. 2.
  • both the side 27 integrated into the side wall 10 and the opposite side 28 can be seen from the chimney 25.
  • the intermediate free cross-section 31 of the chimney has a thickness 34 which is somewhat greater than the maximum thickness 33 of the tongue 17.
  • the tongue 17 protrudes from the integrated side 27 beyond the upper edge of the side wall 10 and is aligned with its outer surface with the Outer surface of the wall 10.
  • the recess 20 running transversely to the longitudinal direction of the tongue 17 can be seen, which has a depth corresponding to the normal thickness of the wall 10.
  • the part of the tongue 17 located outside this recess 10 serves as a locking element, the outer surface of which has a crowning with the radius R.
  • the thickness 33 of the tongue 17 must be greater than the normal thickness 35 of the wall 10.
  • the recess 21 which serves as a snap-in receptacle and is designed in accordance with the snap-in element, that is to say the free end of the tongue 17.
  • This recess 21 is separated from the lower edge of the wall 10 by an edge 24, the height of which corresponds to the width of the recess 20 on the tongue 17.
  • FIG. 4 shows a hinge in cross section, specifically cut along the line C-D according to the view of a trough according to FIG. 2. The hinge-like interaction is shown in FIG. 6.
  • both the outer, integrated side 36 and the opposite side 37 can be seen.
  • the narrow sides and the side of the chimney opposite the wall of the trough merge into the floor 30 of the trough, so that, despite the continuous chimney, it has a tight connection between the floor 30 and the surrounding walls.
  • Fig. 2 the extension 12 can be seen, which extends from the outer side 36 of the fireplace 11 over the upper edge of the rear wall 8 of the tub. Above the upper edge of the wall 8 there is immediately a recess 13 running parallel to this edge in the outside of the extension 12. The depth of the recess 13 corresponds to the normal thickness of a wall of the tub 2. This creates a cranked cross-section of the extension 12. In the vicinity of the lower edge, this outer side 36 has an opening 14 which also runs transversely to the edge of the wall and which is formed by an edge strip 15 is separated from the lower edge of this wall. The width of this edge strip 15 corresponds to the width of the recess 13 in the outer surface of the extension 12. The dimensioning of the opening 14 in turn corresponds to the size of the cranked free end of the extension 12 above the recess 13.
  • this side 36 again has the normal wall thickness of a trough 2.
  • the greater thickness of this extension 12 can be maintained up to the vicinity of the opening 14 along the outer side 36.
  • the extension 12 of the lower trough 2 is already in the free cross-section 39 of the chimney 11 of the upper trough 2.
  • the edge strip 15 of the outer side 36 of the upper trough 2 is already largely inside the recess 13 in the extension 12 of the lower trough.
  • this clearance 41 present in the latching device in the direction of the side walls 10 is not sufficient in order to offset the hinges 22 so far transversely to one another when the troughs 2 are engaged, that the hinge 22 can come out of engagement and thus lift the upper trough 2 upwards.
  • FIG. 5 also shows a section of one of the guide elements 26, as is present on the front wall 9 and also on the side walls 10 of the tubs 2 according to FIG. 2, if these have such a free length that, owing to the small wall thickness, which is due to the weight limitation, an excessive bending of these walls is possible.
  • These guide elements 26 consist of a band-shaped, vertical reinforcement of the wall on the inside thereof and a slight protrusion of this band-shaped region beyond the upper edge of the wall. When two troughs sit on top of one another, these guide elements 26 protrude into corresponding recesses on the underside of the overlying trough and thus necessitate mutual stiffening of the walls lying one above the other.
  • FIG. 2 it can be seen that the rear wall 8 of the tub 2 has two hinges 22 next to each other, and a latching device 5 on each side wall 10 in the vicinity of the front wall 9.
  • This closure is childproof when the locking devices 5 are at a sufficient distance 40 from the front wall 9, so that the shorter length of the fingers of a child compared to those of an adult is no longer sufficient to simultaneously push the thumbs onto the front wall 9 to be able to exercise the upper tub while the tongues 17 are pressed in from the side.
  • the interior of this container can also be optimized by lining the inside surfaces of the walls of the container and also the floors with foam or another elastic material , for example in the thickness of the chimneys 11 and 25, so that there is a smooth line on the inside of the walls of the container.
  • foam or another elastic material for example in the thickness of the chimneys 11 and 25, so that there is a smooth line on the inside of the walls of the container.
  • either the floor or the walls of each tub and, if necessary, the underside of a tub serving as a cover can be completely or partially lined with a Velcro covering to fix the items within the container.
  • the items to be specified are e.g. glued with small pieces of the corresponding counter material to the Velcro covering and can thus be fixed to the lining made of Velcro covering by simply pressing on and still be removed at any time.
  • both the chimneys of the locking device and the chimneys of the hinges can be arranged on the troughs so that not their outer but their inner side are flush with the walls of the troughs in order to have a smooth shape of the inner surface of the walls of the container even without a lining achieve.
  • This is paid for with the disadvantage that the outer surfaces of the container are then no longer flat, so that other objects easily get caught on the projecting chimneys and damage them when the container is being transported.
  • the inner position of the chimneys is therefore usually preferred.
  • the chimney-like design also makes it possible to keep the interior of the container tight at the edge between the floor and the surrounding walls by connecting the base 30 to the inside side 37 and the narrow sides 38 of the fireplace, although from the underside the extension 12 of the tub underneath must be inserted into a cavity and without protruding hinge elements on the outside of the tub.
  • the advantage of the chimney 25 is that the play in the direction of the plane of the tongue 17 can be determined by its narrow sides 29.
  • the inner side 28 of this chimney 25 limits the bending of the tongue 17 when pressure is exerted thereon for the purpose of opening the latching device. This will Damage or the complete breaking of the tongues 17 when opening the container is largely excluded.
  • the hinge 22 can be further developed according to FIG. 7: A projection 42 is attached to the lower end of the inner surface of the side 37 of the chimney 11, by means of which the free cross-section 39 of the chimney 11 is reduced to a lower, free width 44 at the lower end. Due to this free width 44, however, it must still be possible to insert the extension 12 of the tub underneath. Since the two troughs are never placed on top of each other due to the latching device, but at an angle 16 as shown in FIG. 6, the necessary free width 44 depends not only on the thickness of the extension 12, but also on the size of the angle 16, under which the upper tub 2 is placed. This is because the effective diagonal 43 of the extension 12, which is always to be defined parallel to the position of the tub 2 to be fitted, increases with increasing angle 16.
  • the angle 16 must be at least large enough that the latching device 5 is already disengaged in order to be able to lift the upper trough freely towards the rear or to be able to put it on from behind.
  • the effective diagonal 43 at the extension 11 is greater than the free width 44 above lying tub, so that the hinge 22 can no longer be separated or assembled. Rather, when the angle 16 is further enlarged, the surface of the extension 12 pointing toward the interior of the container lies against the inclined surface of the projection 42 pointing towards the inside of the chimney 11. If the center of gravity of the upper part of the container is already behind the extension 12, the container automatically remains in the open position without having to be held. The size of the maximum value of the angle 16 thus depends on the position of the inclined surface on the inside of the projection 42.
  • the free width 45 at the upper end of the chimney 11 must in turn be greater than the width 46 with which the extension 42 at the lower end of the channel 11 reduces its free cross-section 39.
