Description

  The present invention relates to a folding box including a bottom surface and a plurality of side surfaces rotatably connected to the bottom surface. The bottom surface has a concave or convex first coupling surface, and at least one side surface has a convex or concave second coupling surface. The second connection surface cooperates with the first connection surface to connect at least one side surface to the bottom surface. At least one of the first connection surface and the second connection surface is cylindrical, and enables rotation about the rotation axis. The first connecting surface and the second connecting surface are prevented from moving in at least one side surface with respect to the bottom surface in at least one first direction orthogonal to the rotation axis and opposite to the first direction. Are arranged as possible in the second direction.

  Folding boxes practically assist in transporting objects. These folded boxes form a box or case that opens at the top in the unfolded state and are flat in the folded state and are therefore easy to store. This is a significant advantage compared to a fixed box. However, the use of a folding box is limited or even avoided. This is because these folding boxes are not as stable as fixed boxes. Furthermore, known locking mechanisms that lock multiple sides against each other, thereby preventing breakage of the box, are often unreliable or have a very complex structure.

  For example, Patent Document 1 discloses a plastic box having a liftable side surface. In this box, after being lifted, the side extension supports the side from the outside at the bottom of the box, thus preventing the side from being pressed from the inside of the box.

  The proposal disclosed in Patent Document 1 is effective only when the side face is completely lifted because of its design. This is disadvantageous because the user of the folding box does not always lift the side completely, or the side may be folded unexpectedly slightly during use. And the mechanisms known in the prior art are no longer effective because the folding box becomes more unstable.

EP 1565382

  Accordingly, an object of the present invention is to provide a folding box that is better protected from being inwardly pressed inward.

The object of the present invention is to provide a folding box of the type described above.
-The bottom has a third connecting surface that is concave or convex;
-At least one side surface has a convex or concave fourth connecting surface;
-At least one of the third connecting surface and the fourth connecting surface is cylindrical, enabling rotation about a rotation axis;
-The third connecting surface and the fourth connecting surface can be displaced in the second direction relative to the bottom of at least one side surface in the first rotating position of the side surface and in the second rotating position; Are arranged to be prevented,
Achieved by a folding box.

  According to the present invention, the third connecting surface is formed on the bottom, and the fourth connecting surface is formed on the side surface. At least one of the third connection surface and the fourth connection surface is cylindrical. In this way, when the side surface is lifted, the third connecting surface and the fourth connecting surface are already engaged, and therefore the side surface can be prevented from being pushed in. The protection against the pushing operation is not limited to the position of the end of the side as in the case of the prior art.For example, when the user of the folding box accidentally does not lift the side completely, It is also effective when folded. In addition, the present invention is based on the finding that a user of a folding box does not always use the folding box according to instructions or instructions, although not intentionally. The generally more stable folding box according to the present invention provides an important contribution to the prior art as the folding box is widely used and frequently used for the transportation of expensive goods. In this case, breakage of the box may be particularly inconvenient.

Advantageous embodiments and developments of the invention are described in the description together with the dependent claims and the drawings.
Advantageously, the second connecting surface and the third connecting surface are convex cylindrical shapes. In this case, one connecting surface on the side surface and one connecting surface on the bottom surface have a convex cylindrical shape. This can be achieved relatively easily from a manufacturing point of view. This is because the rotary bolt can be molded on the side surface and the curved portion can be molded on the bottom.

Moreover, it is advantageous that the first connecting surface and the fourth connecting surface are concave cylindrical shapes.
In this case, the connection surface on the side surface and the connection surface on the bottom surface have a concave cylindrical shape. This variant with the variant embodiment described above is particularly advantageous. This is because, in this case, the two cylindrical surfaces cooperate with each other, and the pivoting of the side surfaces is particularly effective.

  In a further advantageous embodiment of the invention, the concave first connecting surface has an angle of 180 degrees, the convex second connecting surface has an angle of 360 degrees, and the convex third connecting surface has an angle of 180 degrees. The concave fourth connecting surface surrounds an angle of 90 degrees. In this case, it is particularly advantageous if the side connecting bolts are arranged in the bottom half shell, since the side faces can be connected particularly easily to the bottom by the half shell. Further, the pressing of the side surface is prevented by a tab having a quarter arc shape cooperating with the semicircular surface on the bottom surface. Of course, the numerical values shown are merely advantageous guidelines and may deviate from these guidelines without departing from the spirit of the invention. Apart from the smaller deviation, which is structurally determined, the third surface may surround only a 90 degree angle.

  It is also advantageous if the first connecting surface and the second connecting surface are locked. In this case, the side and bottom surfaces are permanently connected together so that they can only be released by a significant force. This locking action can be achieved, for example, by the half shell at the bottom of the folding box surrounding an angle greater than 180 degrees. Alternatively, tabs may be formed for this purpose. If the side bolt is then pushed into the half shell, the half shell will lock into place when a certain force is exceeded.

It is particularly advantageous for the first direction parallel to the bottom surface to be directed away from the interior of the folding box. In this variant of the invention, the side surface can only slide out of the half shell in the extended position and in the direction inside the folding box. The folding box with the side wall in this position is in the rest position and the object is not generally transported in this position, so that the action of the folding box is significantly impaired by the side sliding out of the bearing unexpectedly. There is no.
A plurality of the above embodiments and development forms can be arbitrarily combined.

For a better understanding of the present invention, the present invention will be described in more detail with reference to the drawings.
First of all, in the various described exemplary embodiments, the same parts are given the same reference numerals and the same names, so that the disclosure contained throughout the description is the same reference. It should be noted that the same parts having the same reference numerals and names can be applied. Also, details regarding the positions used in the description, such as top, bottom, side, etc., relate to the drawings described and represented at that time, and adjust to the new position if the position is changed. It should be. Still further, individual features or combinations of features of the various exemplary embodiments shown and described may represent independent solutions or inventive solutions.

  Here, although the exemplary embodiments show various possible embodiments of the folding box according to the present invention, the present invention is not particularly limited to the various embodiments shown thereby. Rather, different and different combinations of the various embodiments are possible, and this changeability is included within the ability of one skilled in the art based on the teachings of the technical approaches. Please keep in mind. Accordingly, all possible different embodiments made possible by combining individual details of the various embodiments shown and described are also within the scope of protection.

  FIG. 1 is a schematic perspective view showing a folding box 1 having a bottom surface 2 and a side surface 3 that is swingably connected to the bottom surface. The arrows represent how the side 3 can be moved from the rest position to the active position.

  Figures 2a to 3c show a first embodiment of the present invention. FIG. 2a shows a convex second cylindrical coupling surface b, here a bolt attached by two coupling webs, and a concave fourth cylindrical coupling, here two tabs with curved sections. A side view of a cross section of a side surface 3 having a surface d is shown.

  FIG. 2b shows a concave first cylindrical connecting surface a, here a half shell for mounting a bolt, and a convex bearing, here two bearing surfaces formed in the form of a semicircular section. FIG. 6 shows a plan view of a cross section of the bottom surface 2 having a third cylindrical connecting surface c. It can be seen from the drawings that these connecting surfaces a to d are not necessarily continuous and may be formed from a partial surface.

  FIG. 3 a shows a cross-section AA showing the mutual relationship between the first connecting surface a and the second connecting surface b, where the bolts on the side 3 are in the half shell of the bottom 2. In this case, the side surface 3 is shown in the folded position, ie the operating position. It can be seen that the side surface 3 cannot move in the first direction x1 with respect to the bottom surface 2 but can move in the opposite second direction x2.

  FIG. 3b shows a cross section BB showing a part of the first cylindrical connecting surface a. The first cylindrical connecting surface a encloses an angle greater than 180 degrees, thus ensuring the locking action between the side surface 3 and the bottom surface 2.

  Finally, FIG. 3c shows a cross-section CC showing the mutual relationship between the third connecting surface c and the fourth connecting surface d, here showing the tabs on the side 3 and the bearing surface on the bottom 2. . Side 3 is then shown in the operative position. It can clearly be seen that the side surface 3 cannot be displaced relative to the bottom surface in the second direction x2 at this position. However, in the rest position this is highly desirable. For this reason, the side surface 3 can only be mounted in the lying position while being locked in place when the side surface 3 is lifted.

  It should be noted here that the bearing clearance is shown relatively large in the drawing for clarity. In practice, narrower tolerances are possible and advantageous. All the cylindrical connecting surfaces a to d have a common axis Z. Although this is advantageous, slight deviations can be tolerated.

  FIG. 4 shows a second modification of the joint connecting portion or the hinge connecting portion. In this case, the first connection surface a and the fourth connection surface d are concave cylindrical shapes, and the second connection surface b and the third connection surface c are convex cylindrical shapes. Unlike the arrangement shown in FIGS. 2a to 3c, here all the connecting surfaces a to d are arranged in one plane. Of course, this is not essential. Instead, the first connection surface a and the second connection surface b may be arranged in one plane, and the third connection surface c and the fourth connection surface d may be arranged in another plane. . The operation of the array shown in FIG. 4 is very similar to that shown in FIGS. 2a to 3c. Only the third connecting surface c surrounds an angle of 90 degrees.

  FIG. 5 shows a third variant similar to the second variant. Instead of being cylindrical, a first coupling surface a, here a rectangular first coupling surface a, is formed, which in some cases is easy to produce from a manufacturing point of view. Similarly, the fourth connecting surface d is not cylindrical but rectangular. The action of the array shown in FIG. 5 is generally very similar to the action of the array shown in FIG.

  FIG. 6 shows a fourth variation of the invention that is similar to the second variation. In this case, a rectangular second connection surface b is formed instead of the cylindrical second connection surface b. Similarly, the third connecting surface c is not cylindrical but rectangular. However, the action of the array shown in FIG. 6 is very similar to the action of the array shown in FIG.

  FIG. 7 shows a fifth modification of the present invention. In the fifth modification, the first connecting surface a is open toward the top. Accordingly, the side surface 3 is mounted from the top in this modification. When the side surface 3 is folded, the fourth connecting surface d carries the lower side of the third connecting surface c, thus preventing the side surface 3 from being pulled upward away from the operating position. It is advantageous according to this arrangement that the force to be transmitted between the side surface 3 and the bottom surface 2 can be distributed on a larger surface.

  FIG. 8 shows a sixth modification of the present invention. In this modification, the first connecting surface opens outward, that is, away from the inside of the box. The side surface 3 is mounted from the outside in this modification. When the side surface 3 is folded, the cooperating connecting surface c and connecting surface d prevent the side surface 3 from being pulled out in the second direction x2.

  Finally, FIG. 9 shows a seventh modification of the present invention. The first connection surface a and the fourth connection surface d are formed in a convex cylindrical shape, and the second connection surface b and the third connection surface c are formed in a concave cylindrical shape. In order to more effectively show the fourth connecting surface d that is not in the cross section shown, the side surface 3 is not represented here by hatching. In this arrangement, the pulling-out operation of the side surface 3 in the second direction x2 is not directly prevented by the cooperating third connecting surface c and the fourth connecting surface d, but indirectly, The side surface 3 has a special feature that prevents it from being pulled apart upwards, and thus prevents the bolt from popping out of the bearing shell.

  It should be noted here that the illustrated variants represent only some of the many possibilities for realizing the idea according to the invention. In particular, the illustrated combination of the first connecting surface a or the second connecting surface b and the third connecting surface c or the fourth connecting surface d is not essential in any manner. Rather, other combinations may be used. For example, the first connection surface a and the second connection surface b in FIG. 4 may be combined with the third connection surface c and the fourth connection surface d in FIG. In addition, the first connection surface a and the second connection surface b in FIG. 6 can be combined with the third connection surface c and the fourth connection surface d in FIG. Finally, in addition to the connecting surfaces a to d having a rectangular cross section, other polygons such as a triangle, a pentagon, and a hexagon may be used.

  The advantage common to all the explicitly or implicitly given variants is that the locking action by the third connecting surface c and the fourth connecting surface d is not only in the end position as in the prior art, This is also an effective point when the side surface 3 is lifted. The wrap angle of the connecting surface shown and suggested is advantageous in this case, but not essential. A person skilled in the art will be able to easily adapt to the specific requirements required. The present invention may be applied to only one or more of the side surfaces 3 of the folding box 1.

  Finally, it should be noted that the components according to the present invention can be suitably formed by injection molding techniques using known plastics. However, other materials, especially a variety of different materials, can of course be used. For example, the first connecting surface a and the second connecting surface b may be made of metal because the connecting surfaces are exposed to relatively high stresses. However, the folding box 1 may be formed entirely from metal.

  Furthermore, the arrangement of the components according to the invention on the longitudinal sides of the bottom surface 2 and the side surface 3 is not associated in any way with the configuration shown in FIGS. 2a and 2b. Any number of the hinges shown can be used. Furthermore, instead of each bolt, it may be a continuous shaft extending over the entire length of the side, in particular a metal shaft.

  Finally, as a formal point, for better understanding of the structure of the folding box 1, the folding box 1 and its components are not partially illustrated in actual scale, but are enlarged in size. Note that these are reduced or reduced or both.

The problems addressed by the independent solution according to the invention can be understood from the description of the specification.
The individual embodiments shown in FIGS. 1 to 9 may primarily constitute the subject of independent solutions according to the present invention. The object according to the invention and the solutions related to the object can be understood from the detailed description and the drawings.
