The technical solution relates to combi box for transport and storage of goods

Background Art

Different containers, crates or boxes are used for transporting various types of goods. The most well-known means of transporting goods are injection molded crates. These are manufactured using injection molds and consist of a uniform material. The disadvantage is the high initial investment in the injection molding tools, the greater the weight, the loss of internal loading dimensions (the necessary bevels after removal from the molds) as the crate height increases. Injected crates have the ultimate useful life. When injected cast material is damaged and no longer useful, it is discarded and ground as a means to recycle plastic. Alternatively, the injection crate may be obsolete or undesirable if the parts for which it is designed are no longer used. Other known goods transport means include construction crates. These are composed of a base of die-cut sheet material (using a punching tool) and a stacking profile (made with an extrusion mold). They are mostly used for production of atypical dimensions compared to injection-molded crates with less demanded quantity. The disadvantages of the construction crates are higher serial costs, often limited load capacity and more expensive recycling. From EP patent application No. 2368683 a crate is known which is formed from a slit injection crate or a construction crate. This slit crate forms the lower portion (lower frame) and the upper portion (upper frame) of the new crate, the intermediate portion being referred to as the sheath between these slit portions. This central part is welded to the lower and upper parts of the slit injection molded crate. The disadvantage of these welded crates is the complexity of aligning the lower and upper parts of the slit injection crate with respect to the central part, where the position must be fixed before welding. The position is fixed by means of notches which are formed on the central portion, the ribs being inserted into the notches, which are on the slit portions of the injection crates. Even rib positioning does not ensure trouble-free alignment of the central portion for cooking the top and bottom portions of the cut injection crate, so the upper and lower portions must be mechanically secured prior to welding, which is considerably disadvantageous.

The essence of the technical solution

The disadvantages of the known means for transporting and storing goods removes the combi box according to the invention. The combi box includes a lower portion and an upper portion, which are formed from a used or new cut plastic injection or construction crate. On the cut portion of the crate, i.e., between the lower portion and the upper portion, a central portion is inserted (inserted), the central portion being different heights. The essence of the technical solution is that the intermediate part is connected to the lower part on the lower part and the locking parts on the upper part to the upper part. The locking joint comprises a first locking portion formed on a vertical rib of the lower portion and a vertical rib of the upper portion. The vertical ribs on which the first locking portion is formed are the original ribs formed on the slit injection or structural carrier. This first locking portion fits into a second locking portion that is formed on the lower periphery and on the upper periphery of the intermediate portion.

According to an embodiment of the second locking part, the locking joint is closed or open. The closed lock joint has a solid centered area around the second lock portion. The open locking joint is formed such that a slit is guided from the second locking portion towards the peripheral side of the central portion. This pruning allows easier coupling and insertion of the second locking portions into the first locking portions formed on the vertical ribs of the lower and upper portions, since the wall

-1 CZ 32109 U1 The middle section with the pruning is more flexible. The lock joint formed by one first lock part and one second lock part is called a single lock joint. In many cases it is necessary to create a combi box, which will be larger in size and bear more weight of the goods to be transported, therefore, the interlocking connections must be doubled. To form the double locking joint, two first locking portions are formed on the vertical ribs of the lower portion and the upper portion, and two second locking portions are formed on the central portion. This type of locking joint is referred to as double closed or double open. The double closed lock joint has a surface around the second lock portion on the middle portion solid. The double open locking joint is formed such that a cut is guided on the second locking portion toward the circumferential side of the central portion, and two superposed second locking portions are also cut through. Although triple or multiple interlocking connections could be made, such an embodiment no longer appears to be practical. In some instances, the use of a combi box will be required, particularly when storing the goods, so that at least one side of the coupled portions is open, i.e., an open area. It may be a shorter front side or a lateral long side, or a combination of sides. While the interlocking connections will provide sufficient strength with the interlocking joints of the combi box, the strength of the bonded portions may still be enhanced by welding them together at several points or by mechanical bonding.

The advantage of the technical solution is the low cost of serial production, almost zero cost of expanding the product line, the use of already worn, partially broken or otherwise unused injection crates, low weight, depending on the type of material used, the necessary stress resistance can be obtained. The material of the individual parts of the combi box will in most cases be plastic, nor will any combination with other materials be excluded. The combi box can be used for the transport of industrial goods, eg in the automotive, engineering, electrical industry, etc., as well as for the transport of food, medicine, toys, etc. goods.

Examples of technical solutions

The combi box 10 shown in Figures 1 to 18 is formed from an injection or construction crate that, when cut, forms a lower frame part 1 and a frame top 2. A middle part 3 is inserted between the lower part 1 and the upper part 2 - the two open side jacket may be of different heights, depending on the purpose of use. The shape of the central part 3 corresponds to the shape of the lower part 1 and the upper part 2. The central part 3 is connected to the lower part 1 with the upper part 2 by means of the locking joints 4. The locking connections 4 are formed on the lower circuit 3.1 and on the upper circuit 3.2 the middle part. 3 and the vertical ribs 1.1 of the lower part 1 and the vertical ribs 2.1 of the upper part 2. According to various embodiments and according to the number of locking joints 4 formed between the connected middle part 3 with the lower part 1 and the upper part 2, the joined parts can be used without subsequent additional protection or can be insured against separation by welding or a mechanical detachable or non-detachable joint. Thus, in all of the embodiments described below, a combi box 10 is provided comprising a structurally configured lower portion 1 and an upper portion 2 formed of an injection or structural crate to which a central portion 3 (central shell) is attached by the locking connection 4.

Figures 1 to 4 show a box W of rectangular shape with four locking joints 4 which are formed on opposite long sides. The arrangement of the locking joints 4 is designed so that the lower part I has on each longer side on one original vertical rib 1.1 a first locking part 4.1 comprising a recess 4.11 and a protruding part 4.12 which remains cut from the original vertical rib 1.1. crates. The first locking part 4.1 on the lower part 1 is placed in diagonal relationship with each other (Figs. 2, 3). Also, the upper portion 2 has on each long side on one vertical rib 2.1 a first locking portion 4.1 comprising a recess 4.11 and a raised portion 4.12 which remains from the original vertical rib 1.1 (FIGS. 2, 4). On the lower circumference 3.1 and on the upper circumference 3.2 of the middle part 3, second locking parts 4.2 are formed opposite the first locking parts 4.1 which form an opening extending through the wall of the central part 3. This opening is shaped so as to engage the raised parts 4, 12 first lock parts 4.1. The second locking part 4.2 is surrounded by a fixed wall of the middle part 3, therefore we call this locking joint 4 closed. Since the locking joint 4 is formed by one first locking part 4.1 and one second locking part 4.2, this locking joint 4 is referred to as one-fold closed (NOTE: for example, in FIGS. 13 and 14 a double closed locking joint is shown). Structural adjustments are made to the lower part ia and to the upper part 2 of the slit crate, leaving vertical ribs 9, which are inserted into the grooves 11 formed on the lower circumference 3.1 and on the upper circumference 3.1 of the joined middle part 3. Two grooves 1T are formed on the short sides the parts to be joined and one groove is formed on the long sides. When joining the central part 3 to the lower part 1 and the upper part 2, the middle part 3 is extended to the lower part 1 and to the upper part 2 until the first locking part 4.1 engages the second locking part 4.2 and thus the locking part is formed. 4. The connection of the central part 3 with the lower part 1 and the upper part 2 by means of four locking joints 4 ensures a sufficiently precise position of the parts to be joined for subsequent fixation of the connected parts. Subsequently, the central part 3 is fixed to the lower part 1 and the upper part 2 during cooking, for example at points 12, or is secured by a detachable or non-detachable joint at points 13 on the short sides of the combi box 10.

FIGS. 5 and 6 show a box 10 of rectangular shape, in which each side of the central part 3 is connected to the lower circuit 3.1 and to the upper circuit 3.2 to the lower part 1 and the upper part 2 by two locking connections 4, the lower part I being the central part 3 is connected by eight locking joints 4 and the same number of locking joints 4 also has a connection of the central part 3 with the upper part 2. The design of the locking joints 4 is designed in the same way as in the example of Figs.

1.1 of the lower part 1 and the vertical ribs 2.1 of the upper part 2 a first locking part 4.1 is formed which engages the second locking part 4.2 formed on the central part 3. This number of locking connections ensures a sufficiently strong connection between the connected parts 1 and 2 with the middle part 3, therefore no further fixation of the parts to be joined is necessary. Also in this exemplary embodiment, the locking joint 4 is formed as a one-way closed, i.e. the second locking part 4.2 on the middle part 3 is surrounded by a fixed surface. However, even this variant of the connection by means of 16 locking joints does not exclude additional fixation, eg by welding.

7 to 16 show different embodiments of the locking joint 4.

FIG. Figures 7 and 8 illustrate an embodiment of a single open lock joint 4. This single open lock joint 4 is formed such that from the second lock portion 4.2 on the lower periphery

3.1 and a cutout 6 facing the horizontal sides 3.11 of the middle portion 3 is provided at the upper periphery 3.2 of the middle portion 3. The first locking portion 4.1 at the upper portion 1 and at the lower portion 2 is formed as in the previous examples. This cut 6 facilitates insertion of the second lock portion

4.2 into the first locking part 4.1 formed on the vertical ribs 1.1 of the lower part 1 and on the vertical ribs 2.1 of the upper part 2.

FIG. Figures 9 and 10 show an embodiment of a single closed locking joint 4, which is formed on a vertical web 2.1 for connecting the upper part 2 with the central part 3, the recess 4.11 of the first locking part 4.1 being dimensioned on the longer part of the vertical rib 2.1 and rising the portion 4,12 is dimensioned on the shorter portion of the vertical rib 2.1. The second locking portion 4.2 formed on the upper circumference 3.1 of the middle portion 3 is made deeper in the wall of the middle portion 3 (FIG. 9). Also, for connecting the lower portion 1 to the central portion 3, the locking joint 4 is formed on the vertical rib 1.1 of the lower portion, the recess 4.11 being dimensioned on the longer portion of the vertical rib 1.1 and the raised portion 4.12 on the shorter portion of the vertical rib 1.1. A second locking portion 4.2 formed on the lower periphery

3.1 of the middle part 3 is made deeper in the wall of the middle part 3 (FIG. 10).

FIG. Figures 11 and 12 show an embodiment of a single open locking joint 4 with the same construction as described for the examples in Figures 9 and 10. The difference of this locking joint is that the second locking part 4.2 is guided towards the horizontal sides 3.11 of the middle part 3 a slit 6 which facilitates insertion of the second locking portion 4.2 into the first locking portion 4.1 at the lower portion i and on the upper portion 2.

FIG. Figures 13 and 14 show an embodiment of a double closed locking joint 4 that connects the central part 3 to the lower part 1 and the upper part 2. The design of the double closed lock comprises the same elements as those described in the previous examples but on a vertical rib

1.1 of the lower part 1 and on the vertical rib 2.1 of the upper part 2 two first locking parts 4.1 are formed. Two second interlocking parts 4.2 are formed one above the other on the lower central part 3.1 and on the upper circuit 3.2, into which the two first interlocking parts 4.1 are inserted. If the rectangular combi box contains two double locks on each of the two lower vertical ribs 1.1 and on the two upper vertical ribs 2.1, then the total number of locking joints around the circumference of the combi box will be 32. with a higher allowable load.

FIG. 15 and 16 show an embodiment of a double open locking joint 4 that connects the central part 3 to the lower part 1 and the upper part 2. Structurally the same locking joint solution as described for the exemplary embodiments in Figs. 13 and 14. is that the second locking portion 4,2 is guided toward the horizontal sides 3.1 of the middle portion 3

Cutting 6 and also between the two second locking portions 4.2 is a cut 7. These cuts 6 and 7 facilitate the insertion of the second lock portion 4.2 into the first lock portion 4.1 on the lower portion 1 and on the upper portion 2.

FIGS. 17 and 18 show a box 10 of rectangular shape consisting of a central part 3 and a lower part 1 and an upper part 2, wherein the central part 3 is connected to the lower part of the upper part of the upper part 2 by a single open locking joint. 7 and 9. One shorter side of the connected portions I, 2 and 3 forms the open side 8. This solution is particularly suitable for storing goods on shelves where the open side 8 is access to stored goods. The open side 8 may also be formed on two opposing shorter sides or on the adjacent shorter and longer sides, and the like.

Although several variants of the connection of the lower part 1 and the upper part 2 with the middle part 3 of the combi box have been described and illustrated, no other different combinations are excluded, e.g. one combi box will be connected at the lower part to the middle part by a double closed interlocking connection and at the upper frame with a single open lock connection. Also, the additional strength of the bonded parts, for example by welding or mechanical bonding, is not excluded.
