Definitions

  • the invention relates to a folding box according to the preamble of claim 1.
  • a folding box is made EP 1785360 .
  • Folding boxes are practical tools for transporting items, since in an unfolded state, they form an open-topped box or box, and are flat in a folded state and therefore easy to stow. Compared to fixed boxes, this is a significant advantage.
  • the use of folding boxes is limited by the usually lower stability or even prevented.
  • the known locking mechanisms which lock the side walls against each other and so prevent collapse of the box, often unreliable or very complex.
  • WO 00/68099 is also a portable, preferably made of plastic container known, which has a substantially rectangular bottom and two pairs of pivotally mounted side walls.
  • bolts which are arranged on two of the side walls, are provided.
  • the bolts can be moved between an unlocking position and a locking position. In the latter, the bolts protrude out of the side wall and engage in a recess of the adjacent side wall. Due to the displacement mechanism of the bolt, the container is technically relatively complicated. For many users or applications, such a box is therefore simply too expensive.
  • the object of the invention is therefore to provide a folding box available which has improved protection against accidental folding.
  • the folding box acts a non-circular, rotatable axle end on a side wall with a holding element on an adjacent side wall together such that the two walls are locked in a first rotational position of the axle end and unlocked in a second rotational direction.
  • the folding box is secured against unintentional collapse, as for folding a multi-stage movement (unlocking with a first movement and collapsing with a second movement) is necessary.
  • the folding box comes with relatively simple and therefore robust locking elements, because the pivot bearing of the axis is easier to accomplish than about a bearing that allows a longitudinal displacement of locking elements.
  • a bearing eg, metal shaft, plastic bearing shell
  • the axle and the bearing grind in operation can be intentionally tight, because the axle and the bearing grind in operation and thus provide an optimal fit of the parts over time.
  • This is made possible by the fact that in the longitudinal direction always the same point of the axis in contact with the same point of storage.
  • this is a clear advantage, since - which unfortunately can happen quite easily unintentionally - the rod-shaped locking elements are often bent and thus only a very loose storage of the locking elements is possible.
  • According to the invention can be achieved by simple means as a high-quality, because tight-fitting, storage by the user.
  • the at least one axle end has a cross section from the group: rectangular with rounded corners, S-shaped, oval, elliptical or flattened circular cross-section. These cross sections are comparatively easy to produce and at the same time very well fulfill a locking function.
  • the at least one axis is automatically rotated by means of a spring in the first rotational position.
  • the axis is therefore in the locked position by default. Unintentional unlocking is counteracted - since this requires the overcoming of a spring force.
  • torsion springs, leaf springs and spiral tension and compression springs come into consideration here, wherein the force generated by a leaf or coil spring should optionally be converted into a torque with suitable measures (levers and the like).
  • the at least one axis is automatically rotated into the second rotational position when the second side wall is opened.
  • the invention thus moves the axis when opening the box by itself, that is, by the pivotal movement of the side wall, in the Entriegelposition, so that the side walls can be pivoted into their end positions without special intervention.
  • the at least one axis is automatically turned into the first rotational position with the aid of the spring when the end position of the second side wall is reached.
  • This variant of the invention represents a combination of the two aforementioned embodiments. On the one hand, unfolding of the side walls to their final position without special movements (ie without a conscious unlocking) allows, on the other hand, the side walls, once they have reached their final position, automatically by the Spring locked. Once the box is fully opened, it can not be accidentally closed. The actions required by the user for safe operation of a folding box are thus limited to a minimum.
  • the at least one axis can be rotated by means of a handle in the first and / or second rotational position. Since the rotation of the axle can be quite cumbersome under certain circumstances without additional aids, in this embodiment of the invention, a handle on the axis is provided, which allows the easy turning of the same.
  • Fig. 1 shows an inventive embodiment of a folding box 1 with a bottom (not shown), pivotally connected to the ground first and second side walls 2 and 3 and arranged on the first side walls 2 holding elements 4.
  • On the second side wall 3 is an axis 5 with two axle ends 5a and 5b rotatably mounted in bearing shells 6, wherein the bearing shells 6 can be integrated in reinforcing ribs 7.
  • FIGS. 2a to 2c show a first embodiment of the invention.
  • Fig. 2a shows a side view of the axis 5 with the first axle end 5a, the lever 8 and the leaf springs 9.
  • the axle ends 5a and 5b are S-shaped curved.
  • Fig. 2b shows how the axle end 5a cooperates with the holding element 4.
  • the axle end 5a is shown in the first rotational position, in which the side walls 2 and 3 are locked.
  • the axle end 5a can be moved to a second rotational position, in which the axle end 5a is unlocked by the retaining element 4, so that the side walls 2 and 3 can be pivoted towards the bottom of the folding box 1.
  • This rotation takes place by operating the lever 8 against the spring force of the leaf springs 9.
  • the second side wall 3 is then pivoted in the direction of the ground, then - when the lever 8 is released again - the axle end 5a slowly rotates back into the through the widening guide gap first rotational position.
  • lever unlocking is done by pressing the lever 8 inwards.
  • the leaf springs 9 rest against the outside of the second side wall 3 and thus build up a restoring force.
  • Fig. 2c finally shows a view of in Fig. 2b shown variant along the first side wall 2 (see also section BB in Fig. 2b ).
  • Good to see here is the shape of the guide gap 10 and its boundary walls, which are flatter in the initial area and higher in the end. Due to the shape of the boundary walls of the guide gap 10 and the relatively large width at the beginning of the same, the axle ends 5a and 5b slip when folding the second side walls 3 particularly well in the associated guide gaps 10th
  • FIGS. 3a to 3c show a second embodiment of the invention.
  • Fig. 3a shows a side view of the axis 5 with the axle end 5a, the lever 8 and the leaf springs 9.
  • the axle ends 5a and 5b are formed in the form of a flattened circular cross-section.
  • Fig. 3b shows how the axle end 5a cooperates with the holding element 4.
  • the axle end 5a is shown in the first rotational position, in which the side walls 2 and 3 are locked.
  • the axle end 5b can be moved to a second rotational position, in which the axle end 5a is unlocked by the retaining element 4, so that the side walls 2 and 3 can be pivoted towards the bottom of the folding box 1.
  • This rotation takes place by actuation of the lever 8 against the spring force of the leaf springs 9. If the second side wall 3 then in the direction of the ground pivoted, the axle end 5b rotates again after passing the retaining element 4 in the first rotational position.
  • the axle end 5a When folding up the second side wall 3, the axle end 5a, as soon as it abuts the holding element 4, automatically rotated because of the eccentric force between the axle end 5a and retaining element 4 in the second rotational position. As soon as the second side wall 3 reaches its end position, however, the axle ends 5a and 5b are rotated by the leaf springs 9 into their first rotational position and then lock the side walls 2 and 3 with the aid of the retaining elements 4.
  • Fig. 3c finally shows a plan view of a corner of the folding box 1, in which the first side wall 2 with the holding element 4 and the second side wall 3 with the axis 5 is shown. Good to see here is how the axle 5b interacts with the retaining element 4.
  • FIGS. 4a to 4c now show an embodiment not according to the invention.
  • Fig. 4a shows a side view of the axis 5 with the axle end 5a, the lever 8 and the leaf springs 9.
  • the axle ends 5a and 5b are hook-shaped.
  • Fig. 4b shows how the axle end 5a cooperates with the holding element 4.
  • the axle end 5b is shown in the first rotational position, in which the side walls 2 and 3 are locked.
  • the axle end 5b can be moved to a second rotational position, in which the axle end 5b is unlocked by the retaining element 4, so that the side walls 2 and 3 can be pivoted towards the bottom of the folding box 1.
  • This rotation takes place by actuation of the lever 8 against the spring force of the leaf springs 9.
  • the axle end 5b turns back into the first rotational position after passing through the retaining element 4.
  • Fig. 4c finally shows a plan view of a corner of the folding box 1, in which the first side wall 2 with the holding element 4 and the second side wall 3 with the axis 5 is shown. Good to see here is how the axle end 5a cooperates with the retaining element 4.
  • the bearing of the axle 5 can advantageously be accomplished by integration of the bearing shells 6 in reinforcing ribs 7 of the second side wall 3.
  • Fig. 5 shows a part of a reinforcing rib 7, in which a bearing shell 6 is arranged (see also section AA in Fig. 1 ).
  • the bearing shell 6 advantageously comprises a little more than a semicircle, so that the axis 5 can be simply clipped in the assembly of the folding box 1.
  • cuts are provided in addition to the bearing shell 6, which allow springs of the bearing shell 6 when clipping.
  • Fig. 6 shows in a side view and a section CC a folding box 1 finally a variant of an axis 5, which is not continuous, but in which the lever 8, the axis 5, in particular in the middle divides, in particular the lever 8 and the axis 5 in the middle region provided with a pulled down deposition.
  • the lever 8 and the axis 5 may be constructed in one piece but also in several pieces.
  • This lever 8, which is pivotally formed below the handle of the folding box 1, can be used in all mentioned variants of the invention.
  • To unlock the lever 8 is folded outwards.
  • the leaf springs 9 lie on the outside of the second side wall 3 and thus cause a restoring force.
  • a mirror-inverted embodiment is conceivable in which the lever 8 is pressed inwards, and the leaf springs 9 lie on the inside.
  • FIGS. 7 and 8 is a detail of another embodiment of the invention, which differs from that according to Fig. 1 derives and differs essentially only by another embodiment of the axle ends 5a and the holding elements 4, shown in plan view and side view.
  • Fig. 7 shows a plan view of a corner of the folding box 1, in which the first side wall 2 with the holding element 4 and the second side wall 3 with the axis 5 is shown. It can again be seen how the axle end 5a interacts with the retaining element 4.
  • the lever 8 ( Fig. 1 ) on the second, in particular short, side wall 3 of the folding box 1 is pressed inwards (in the direction of the box interior), or, as already described above, the mirror-inverted embodiment variant is also possible.
  • the axis 8, which is in particular firmly connected to the lever 8, is set in a rotary motion.
  • a taper 11, ie the axis 5 is formed tapered, arranged in the first side wall 2, that is, the holding element 4, engages and locked.
  • This lock is shaped so that it in the closed state, ie erected state of the side walls 2, 3 of the folding box 1, locked.
  • the holding element 4 is provided with two opposing shells 12 which receive the tapered axle end 5a of the axle 5 ( Fig. 8 ).
  • the lock is released, so that the oval-shaped in cross-section axle end 5 a can be brought out of engagement with the shells 12.
  • the second side wall 3 can be folded inwards.
  • folding the second side wall 3 in the holding element 4 in turn provide the leaf springs 9 ( Fig. 1 ) that the lever 8 ( Fig. 1 ) is brought back to its starting position or rest position.
  • the axle end 5a is pressed into the flexible shells 12.
  • the lever 8 remains in its initial position.
  • the folding box 1 is thus locked again.
  • the axis 5 during assembly of the lock in the spring openings or the bearing shell 6 ( Fig. 5 ) of the reinforcing rib (s) 7 are clipped.
  • the axis 5 may be made of metal, for example.
  • the lever 8 and / or the leaf springs 9 may also be made of metal and welded to the axis 5. It is also conceivable that the lever 8 and / or the leaf springs 9 are made of plastic and are sprayed for example on the axis 5. Finally, it is also possible to produce axis 5, lever 8 and the leaf springs 9 in one piece from metal or plastic. For the latter variant, in particular cost-effective and in the form almost completely freely selectable injection molded parts into consideration.
  • the axle ends 5a and 5b can be given any desired shape during injection molding, but can also be produced by grinding (for example flattening of a wire that is circular in the raw state) or pressing.
  • axle ends 5a and 5b made of plastic can be plugged onto an axle 5 made of metal, but it is also possible to attach axle ends 5a and 5b made of metal to an axle 5 made of plastic.
  • axle ends 5a and 5b protrude on both sides of the second side wall 3
  • other variants are conceivable, of course.
  • a first axle end 5a can protrude on the second side wall 3.
  • the folding box 1 is locked only on one side.
  • two axes 5 are arranged with a total of four axle ends.
