Description

Quick lock stackable suitcase.

The invention relates to a stackable suitcase with a bottom part and a cover part according to the preamble of the claim 1, as well as to an assortment of corresponding suitcases according to the preamble of claim 10.

Monohull suitcases of the type mentioned above, which are structured vertically stackable, for easy storage or transport. The stability of a pile of such cases is they occupy some highlights and cavities, in each case corresponding, arranged on the outer surfaces of the housing parts, that in the case of superimposed suitcases they hook each other and This mode effectively prevents lateral sliding of luggage individual.

These types of suitcases are used of multiple ways in the field of crafts to be able to transport portable machine tools, for example power tools such as circular hand saws, sanders or similar, between places of employment.

To also prevent impassable paths that individual suitcases fall, it was proposed in EP 0 555 533 A1 provide for the corresponding lower parts of the suitcases means of union which, with the formation of a transport unit formed by several suitcases together, enable a detachable joint between the lower parts of two suitcases located in each case one on top of a pile of suitcases. To the at the same time the solution indicated there starts particularly from a suitcase which is composed of a bottom in the form of box or monocoque and a flat lid part that is rotatable to the bottom. In a pile of cases of this type is fixed by interlocking the lid of in each case a lower suitcase between the lower part of the lower suitcase and the lower part of the upper suitcase arranged directly above.

A similar tool case is given to know in WO 02 11955 To which with respect to the This application serves as a state of the art according to Art. 54 (3) and rule 158 (1) of the CPE. The briefcase of tools comprise, according to Fig. 2, there is a part bottom and a lid part, where in the two-sided area front of the bottom two are planned first stirrup-shaped fasteners which interact with such way with two second fasteners arranged directly on the bottom of a suitcase directly contiguous that a stable detachable joint is formed. Through this union is caused, disadvantageously, also that the part of lid of the suitcase arranged there underneath is no longer allowed to open, given that is immobilized or fixedly imprisoned between the two lower parts of the upper and lower suitcase.

In addition, document DE 299 00 082 U discloses a similar tool receptacle. From Fig. 2 shown in that case it follows that this tool receptacle does not allow that in a stack formed by two tool receptacles of this type the receptacle found in each case below can be still open Since the clamps there are rotatably arranged at the bottom of the receptacle and they engage in a nerve of the lower part located in each case over. Therefore in that case, the receptacle lid arranged in each case down in the stack is no longer allowed to open. By means of the overlapping arrangement of the front clamp, It also effectively prevents opening of the lid.

The solutions described above suffer consequently of the disadvantage that if there is a battery you can only open the suitcase that is in each case above, since the remaining luggage covers are immobilized or fixedly fixed between suitcases individual and with it are inaccessible out.

In addition the field of use of this solution known is limited to suitcases with a relatively lid part flat. In particular, this solution cannot be used in "monocoque suitcases" most used, which have two semi-thick helmets equally thick.

In addition, from the document DE 39 34 760 A1 a suitcase in the form of a parallelepiped formed by two parts of suitcase is disclosed in which the two parts of the suitcase are connected, firstly, to each other in positive connection by means of two rails Profiles that engage each other and the definitive stack fixing of the two suitcase parts takes place in the direction of guide of the profiled rails by means of a lock / interlock connection arranged on a front side of the suitcase parts. Unlike the solution described above, in this case the two parts of the suitcase are left open independently of each other also after
fixation.

However, in this solution it is disadvantageous that in at least one of the two parts of the suitcase there is a profiled rail that necessarily protrudes outward, raised on the outer side of the suitcase, which makes handling in each case of the part of the suitcase as well as additionally represents a danger of injury to the user. Furthermore, the fixing of these suitcase parts is relatively complex, where the lateral introduction of the first profiled rail in the second profiled rail can be carried in the case of heavy suitcase parts by the user only through a notable use of
force.

The present invention poses the problem of perfecting a stackable suitcase of the type mentioned at the beginning with a view to avoiding the aforementioned disadvantages and in particular making possible the fixing of a stack as simple and quick as possible of at least two suitcases with the formation of a transport unit. In particular, it should be avoided at the same time that a lid part of a suitcase disposed in a pile of suitcases is not immobilized or fixed in such a way that the lid part can no longer be opened. In other words, it must also be guaranteed in the case of a suitcase stack formed that all the suitcases in the suitcase stack can be opened, and regardless of their position inside the suitcase stack. At the same time the pile of suitcases must guarantee a great stability against lateral sliding of individual suitcases. In addition, fasteners that protrude above the surface of the surface should be avoided as far as possible.
suitcase.

This problem is solved by characteristics of the independent claims. The advantageous improvements are the subject of the claims subordinates

As a peculiarity the stackable suitcase according to the invention provides that in the area of at least two front sides from the bottom are arranged at least two first fasteners in the form of stirrup and in the area of at least two front sides of the lid part are at least two second fasteners, where the first elements of fastening the bottom of a first suitcase can be detachably connected with the second elements of clamping the cover part that is in contact with the part bottom of a second suitcase, so that it can be set a stable detachable joint between the bottom of the first suitcase and the cover part of the second suitcase.

Especially, unlike the solution described in EP 0 555 533 A1, is attached here in each case, for example, the bottom of a suitcase located in each case on top of the lid of a suitcase located below it. This automatically makes it possible for the suitcase located in each case below it can still be opened in the provision stacked, that is, when for example a suitcase.

The first fasteners are formed preferably in each case by a folding or rotating part that can be rotated, where these folding or rotating parts can form a detachable interlocking joint with second elements clamps also preferably formed as an element of interlocking Folding or rotating parts are at the same time formed flat, with which these, once the fixing, protrude only slightly at the bottom. The Folding or rotating parts can be formed foldable or swivel by a hinge arranged at the bottom.

It can also be provided that the pieces Folding or rotating crimp for blocking in a profiling in the form of a tongue or an interlocking rail. With it performs a type of "quick closing" that, in addition to this, allows an especially stable lateral fixation of the housing parts of adjacent suitcases.

It is understood that the function of the parts of housing mentioned as bottom or cover part is in certain arbitrary measure and, according to this, the arrangement of the elements of fastening on the bottom and on the lid part can be also completely inverse, that is to say that the folding parts and swivels can be arranged in the lid part and the interlocking elements at the bottom. The advantages of invention are not however affected by it.

In an embodiment particularly Advantageously the rotating parts can be folded if they are not used in a notch provided on the outer side of the bottom. For this purpose the form is additionally advantageous. essentially flat construction of the rotating parts. The Notch can present at the same time a recess, for simplify unlocking and manual deployment of parts notch swivel.

In addition, it can be provided that the suitcase present a locking mechanism for detachable attachment of the two shell parts of an individual suitcase, where the elements of this mechanism are formed identical to those of the provision of Union.

To prevent an even more effective way relative displacement of different housing parts Suitcases from a pile of suitcases can be provided on the sides exterior of the housing parts in each case a profiling exterior with in each case projections and cavities that engage some in others in a complementary way.

In another embodiment it is provided that in an inner side of at least one of the two housing parts retention elements are arranged for retention preferably of instructions for use, for example for explain the handling of the connection arrangement according to the invention mentioned above.

The proposed stackable suitcase makes it possible, thanks to the proposed joint arrangement, a fixation or blocking of a suitcase stack consisting of two suitcases with only one handle by simple deployment and interlocking of at least two rotating or folding parts and therefore a fixing or lock that can be carried out relatively easily and fast At the same time the own weight of the suitcases plays in each case only a subordinate role since the suitcases must be arranged, during fixing / locking, only ones together to others or one over the other and, in particular, should not take place no relative movement of the suitcases about the others.

The invention also enables the formation of a pair of suitcases with different suitcase sizes, where on a large suitcase, that is a thick suitcase, in which it is transported for example a heavy tool, a smaller suitcase, that is, thinner, in which they are transported for example accessories for the tool. In this case the user you can open the large suitcase too even if a Smaller suitcase is arranged and held on top. The transport of this pile of suitcase then takes place advantageously in the transport unit formed by stacking.

In addition the proposed union provision allows also a stable horizontal juxtaposition, which can be Set up two or more suitcases quickly and easily formation of a side case pile, that is arranged horizontally.

The invention can be used in suitcases throughout type as long as, as usual in monocoque cases mentioned, are formed by two housing parts that have dimensional stability formed in the form of semi-hull, shaped cash or similar.

The invention is explained below with greater detail, referring to the attached drawings, from a example of a preferred embodiment. In the drawings refers to the same or functionally the same characteristics or similar by identical reference signs, in which:

Fig. 3 represents an enlargement of a section of the side view shown in Fig. 2 to continue the explanation of the connection arrangement according to the invention,

Fig. 4, represents a side view enlarger of an external profile, which features highlights and cavities that engage in each other, of the housing parts of a suitcase to prevent slipping suitcases located together from a pile of suitcases,

Fig. 5a, represents an interior view of a open suitcase; Y

Fig. 5b, represents a detailed view of the top monocoque (cap) shown in Fig. 5a in view side.

Fig. 1 shows in a side view a battery of suitcases formed by two suitcases 10, 12 according to the invention. The individual suitcase 10, 12 consists of a lower part 14 in the form of monocoque and a cover part 18, also formed in the form of monocoque, swivel connected by a hinge 16 with the part lower 14. The two housing parts 14, 18 also collide, as is known in itself, with each other in a shutter song 20.

In the example of the embodiment shown, suitcases 10, 12 also have support feet 22, 24 by which suitcases 10, 12 can be placed, in place of stacking on each other shown, vertically ones next to others on an essentially flat floor (not shown), with which is formed so to speak a pile of suitcases formed sideways.

It should be noted that the structuring shown of the two housing parts 14, 18 it is only by way of example and that these can be completely differentiated in each case by the monocoque thickness 26, to the extent that in the two parts of housing 14, 18 is guaranteed at least some stability basic p. ex. dimensional stability.

In addition it is not about the housing parts 14, 18 are formed in monocoque form. In this way they are imaginable also box-shaped or similar conformations.

It should also be noted that in the pile of suitcases shown is not about whether the suitcases are placed on others or laterally next to each other by the feet of Support shown.

In Fig. 1 you can especially see a connection arrangement according to the invention, also in front view. The joining arrangement is composed in the embodiment example of a stirrup-shaped rotating part 28 (visible here) represented in locked position, which can be rotated by a hinge 29 arranged in each case on at least two sides front of the housing parts 14, 18, and an element of interlocking 30 provided in this representation covered by the rotating part 28, in which the rotating part 28 crimps, with the blocking target, by profiling or a rail of interlocking 42 (Fig. 2) in the form of a tongue that is not visible also here. The hinge 29 is arranged especially in such so that the rotating part 28 is folded, if not use, in a notch 46, 46 '(Fig. 2) provided for purpose for it, on the same front side or, as here, on the adjacent to the cover part 18, as indicated in Fig. 1 by reference sign 32, although it can be seen with greater clarity still in Fig. 2.

In addition, Fig. 1 shows a zone 34 partially sectioned from the lower suitcase 12 in which another one is arranged locking mechanism 35, also shown sectioned, by which monocoque halves 14 'and 18', as it is known per se, they can be connected or locked together in a detachable way. In correspondence with the connection arrangement 28-30 described, the locking mechanism 35 has a rotating part 36 ' (correspondingly the upper suitcase a rotating part 36) swiveling on a hinge 37, which does not crimp positive in a corresponding interlocking rail 38.

It should be noted that rotating parts 28 and 36 they are formed identical in the present example, which for the components of the connection arrangement 28-30 and the mechanism lock 35 it is not necessary to prepare parts advantageously different constructive.

Fig. 2 shows the two suitcases 10, 12 in one orthogonal side view to Fig. 1. Suitcases 10, 12 are represented sectioned in the middle 39 left, to continue explaining in the sectional view the joining arrangement 28-30 according to the invention.

The rotating part 28 is represented both in an opening position 40 represented by strokes and in the closed position 28. For the removable connection of the lower suitcase 10 with the upper suitcase 12, the rotating part 28, arranged in the lid portion 18 of the lower suitcase 10, is connected positively with a tongue-shaped interlocking rail 42, arranged on the front side of the lower part 14 'of the upper suitcase 12. In the present embodiment, a profile 44 arranged in the rotating part 28 is interlocked in the interlocking rail 42
mentioned.

Fig. 2 further explains the notch 46, 46 ', only indicated in Fig. 1, for accommodation in each case of the rotating part 28, 28 'when it is not used. This notch 46, 46 'also has a recess 47, 47' which it serves to simplify the user's unlocking and deployment of the rotating part 28, 28 'of the notch 46, 46'.

Enlargement of a section of the side view shown in Fig. 2 depicted in Fig. 3 shows the individual components of the joint arrangement according to the invention again in the expanded representation.

A side view is shown in Fig. 4 enlarger of an external profiling of the housing parts first and second to prevent slipping of suitcases located next to each other or one above another of a pile of suitcases. The external profiling presents in each case highlights 50, 54 and cavities 52, 56 that engage each other in a complementary way, which effectively prevent a relative displacement of the two suitcase halves in the indicated direction 58.

Figures 5a and 5b show, finally, a Inside view of an open suitcase. On the inner side 60, preferably on the inner side of the lid portion 18 described previously, retention elements 61, 62 and 64, by which they can be fastened, preferably imprisoned, for example, instructions for use for handling of the connection arrangement 28-30 described above and / or a device stored in the suitcase. Through the retention elements 61, 62 and 64 the instructions for use are securely fastened, on the one hand, also during the use of the suitcase and, on the other, you can consult the instructions for use well after suitcase opening. Fig. 5b shows the upper part again of the inside view of the suitcase shown in Fig. 5a in a laterally sectioned view.
