Description

Technical field

Technical solution of a station wagon box for transport and storage of goods.

Prior art

Different packages, crates or boxes in which the goods are stored are used to transport different types of goods. Injected crates are among the best known means of transporting goods. These injection crates are manufactured using injection molds and are made of a uniform material. The disadvantage is the high initial investment in injection tools, higher weight, with increasing height of the crate, loss of internal loading dimensions (necessary bevels after removal from the molds). Injected crates have a finite useful life. When the injection mold is damaged and is no longer useful, the entire crate is discarded and ground as a means of recycling plastic. Alternatively, the injected crate may be obsolete or undesirable if the parts for which it is designed are no longer used. Other known means of transporting goods include construction crates. These are composed of a base of die-cut sheet material (by means of a die-cutting tool) and a stacking profile (produced by means of an extrusion die). They are mostly used for the production of atypical dimensions compared to injected crates in smaller demanded quantities. The disadvantages of construction crates are higher serial costs, often limited load capacity and more expensive recycling. From EP patent application no. 2369693 a crate is known which is formed from a cut injection molded crate or a construction crate. This slit crate forms the lower part (lower frame) and the upper part (upper frame) of the new crate, a middle part, which is referred to as the casing, is inserted between these slit parts. This middle part is welded to the lower and upper part of the cut injection molded crate. The disadvantage of these welded crates is the complexity of placing the lower and upper part of the cut injected crate against the middle part, when it is necessary to fix the position before welding. The position is fixed by means of notches which are formed on the middle part, while ribs which are on the cut parts of the injected crates are inserted into these notches. Even fixing the position by means of the ribs does not ensure a trouble-free seating of the middle part for welding the upper and lower part of the cut injection crate, therefore the upper and lower part must be mechanically secured before welding, which is considerably disadvantageous. Another disadvantage of this crate is that it is no longer usable in case of damage.

The essence of the technical solution

The disadvantages of the known means of transport and storage of goods are eliminated by the combi box according to the technical solution. The combi box contains a lower part and an upper part, which are made of used or newly cut plastic injection-molded or structural crates. On such parts of the crate, t. j. between the lower part and the upper part, a middle part is inserted (inserted), which is formed by a casing with two open sides, this middle part being of different height. The essence of the technical solution lies in the fact that the inserted middle part is connected by one open side on the lower circumference to the lower part and by the other open side on the upper circumference to the upper part by locking joints. The locking joint comprises a first locking portion formed on the vertical rib of the lower part and the vertical rib of the upper part. The vertical ribs on which the first locking part is formed are the original ribs formed on the cut injection or structural crate. This first locking part fits into the second locking part, which is formed on the lower circumferential side and on the upper circumferential side of the shell of the inserted middle part.

According to an embodiment of the second locking part, the locking joint is closed or open. The closed locking joint has a solid surface on the middle part around the second locking part. The open locking joint is formed in such a way that a cross section is guided from the second locking part towards the open side of the middle part. This cross-section allows easier connection and insertion of the second locking parts into the first locking parts formed on the vertical ribs of the lower and upper part, because the wall of the middle part with the cross-section is more flexible. The locking joint formed by one first locking part and one second locking part is called a single locking joint. In many cases, it is necessary to create a combi box that will be larger in size and carry a greater weight of transported goods, so it is necessary to double the locking joints. To form a double locking joint, two first locking parts are formed on the vertical ribs of the lower part and the upper part, and two second locking parts are formed on the middle part. This type of locking connection is referred to as double closed or double open. The double closed locking joint has a fixed area around the second locking part on the middle part. The double open locking connection is formed in such a way that a cross section is guided from the second locking parts towards the open side of the middle part and the two second locking parts placed one above the other are also connected in cross section. Although triple or multiple locking connections could be formed. no longer seems practically appropriate. Vnie

In which cases the use of a combi box will be required, in particular when storing goods, that at least one side of the connected parts be open, i. j. formed an open area through which the tovardo box will be inserted or removed. It can be a shorter front side or a longer side side, or a combination of sides. Although the locking joints will provide sufficient strength by locking the joints of the combi box, the strength of the joints can be further strengthened by welding at several points or by mechanical joining.

The advantages of the technical solution are low costs for series production, almost zero costs for expanding the product line, use of already worn, partially broken or otherwise unused injection or construction crates, low weight, depending on the type of material used it is possible to obtain the necessary load resistance. The material of the individual parts of the combi box will in most cases be plastic, and the combination with other materials is not excluded. The combi box can be used to transport industrial goods, e.g. in the automotive, engineering, electrical industry, etc., as well as for the transport of food, medicine, toys, etc. goods.

Examples of embodiments

The combi box 10 for transporting and storing goods shown in Figures 1 to 18 is formed from a conventional or used injection or construction crate. This conventional injection or construction crate will be cut in about half, thus forming the lower part 1 (hereinafter referred to as lower frame 1) and upper part 2 (hereinafter referred to as upper frame 2). Between the lower frame j and the upper frame 2, a middle part 3 is inserted, which is formed by a casing with two open sides, this middle part

S K 8262 Yí part 3 can be of different heights depending on the type of transported or stored goods. In shape, this middle part 3 corresponds to the shape of the lower frame 1 and the upper frame 2. This middle part 3 is connected by open sides to the lower frame 1 and the upper frame 2 by locking joints 4. Locking joints 4 are formed on the lower circumferential surfaces 3.1 and upper circumference 3.2 of the middle part 3 and on the vertical ribs 1.1 of the lower frame 1 and on the vertical ribs 2.1 of the upper frame 2. According to different embodiments and according to the number of locking joints 4 formed between the joined middle part 3 with the lower frame 1 and the upper frame 2 used without further protection or can be secured against separation by welding, or by mechanical detachable or non-detachable joints. In all the described embodiments, a combi box 10 comprising a structurally lower frame j and an upper frame 2 formed from an injection or structural crate is thus provided. by which the middle part 3 (middle shell) is connected by a locking joint 4.

In FIG. 1 to 4, a combi box K) of rectangular shape is shown with four locking joints 4, which are formed on opposite long sides of the connected parts. The layout of the locking joints 4 is solved in such a way that the lower frame j. 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 from the original vertical rib 1.1 of the cut crate, formed. The first locking parts 4.1 on the lower frame 1 are placed diagonally opposite each other (Figs. 2 and 3). Also, the upper frame 2 has on each other side on one original vertical rib 2.1 formed a first locking part 4.1 comprising a recess 4.11 and a protruding part 4.12, which remains from the original vertical rib 1.1 (Figs. 2 and 4). On the lower circumference 3.1 and on the upper circumference 3.1 of the middle part 3, in contrast to the first locking parts 4.1, second locking parts 4.2 are formed, which form an opening passing through the wall of the middle part 3. This opening is shaped so that the protruding parts 4.12 of the first locking part 4.1 fit into it. . The second locking part 4.2 is surrounded by a fixed wall of the middle part 3, therefore this locking connection 4 is called 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 a single closed locking part (for example, in Figs. 13 and 14 a double closed locking joint is shown, see further a description of these picture). For greater stabilization of the joined parts, structural modifications are made on the lower frame 1 and on the upper frame 2 of the cut crate and vertical ribs 9 are left, which are inserted into grooves 11 formed on the lower circumference 3.1 and on the upper circumference 3.2 of the joined middle part 3. Two grooves 11 are formed on the shorter sides of the joined parts, and one groove 11 is formed on the long sides. When connecting the middle part 3 to the lower frame 1 and the upper frame 2, the middle part 3 is stretched on the lower frame 1 and on the upper frame 2 until the first locking part 4.1 engages the second locking part 4.2, thus forming a locking part. The connection of the middle part 3 to the lower frame 1 and the upper frame 2 by means of four locking joints 4 ensures a sufficiently precise position of the joined parts for their possible subsequent fixation by means of a mechanical connection, e.g. by welding in points 12 or by securing with a detachable or non-detachable joint in points 13 on the shorter sides of the combi box 10.

In FIG. 5 and 6 show a rectangular combi box 10, each side of the middle part 3 being connected on the lower circumference 3.1 and on the upper circumference 3.2 to the lower frame 1 and to the upper frame 2 by two locking joints 4, the lower frame 1 being in total with the circumferential side 3.1. of the middle part 3 connected by eight locking joints 3 and the same number of locking joints 4 also has the connection of the circumferential side 3.2 of the middle part 3 with the upper frame 2. The embodiment of the locking joints 4 is structurally solved as in the example of fig. 1 and 2, t. j. on the vertical ribs 1.1 of the lower frame 1 and on the vertical ribs 2.1 of the upper frame 2 a first locking part 4.1 is formed, which fits into the second locking part 4.2 formed on the middle part 3. This number of locking joints ensures a sufficiently strong connection between the joined frames j. and 2 with the middle part 3, therefore it is no longer necessary to make further fixation of the joined parts. Also in this exemplary embodiment, the locking joint 4 is formed as a single closed, i. j. the second locking part 4.2 on the middle part 3 is surrounded by a fixed surface. However, even this variant of connection by means of 16 locking joints does not exclude sufficient fixation, e.g. welding

In FIG. 7 to 16 show different variants of the embodiment of the locking joint 4.

FIG. 7 and 8 show an embodiment of a single open locking joint 4. This single open locking joint 4 is formed such that a cross section 6 is formed from the second locking part 4.2 on the lower circumference 3.1 and on the upper circumference 3.2 of the middle part 3 towards the open sides of the middle part 3. The first locking part 4.1 on the upper frame 1 and on the lower frame 2 is formed in the same way as in the previous exemplary embodiments. This cross-section 6 facilitates the insertion of the second locking parts 4.2 into the first locking parts 4.1 formed on the vertical ribs 1.1 of the lower frame 1 and on the vertical ribs 2.1 of the upper frame 2.

FIG. 9 and 10 show an embodiment of a single closed locking joint 4, which is formed on the vertical rib 2.1 for connecting the upper frame 2 to the middle part 3, the recess 4.11 of the first locking part 4.1 being dimensionally made on the longer part of the vertical rib 2.1 and the protruding part 4.12 being dimensionally made on the shorter part of the vertical rib 2.1. The second locking part 4.2 formed on the upper circumference 3.1 of the middle part 3 is made deeper in the wall of the middle part 3 (Fig. 9). Also for connecting the lower frame

With K 8262 Y 1 with the middle part 3, a locking joint 4 is formed on the vertical rib 1.1 of the lower frame 1, the recess 4.11 being dimensionally formed on the longer part of the vertical rib 1.1 and the protruding part 4.12 on the shorter part of the vertical rib 1.1. The second locking part 4.2 formed on the lower circumference 3.1 of the middle part 3 is made deeper in the wall of the middle part 3 (Fig. 10).

FIG. 11 and 12 show an embodiment of a single open locking joint 4 with the same design as described for the examples in fig. 9 and 10. The difference of this locking joint is that a cross section 6 is formed from the second locking part 4.2 towards the open sides of the middle part 3, which facilitates the insertion of the second locking part 4.2 into the first locking part 4.1 on the lower frame 1 and the upper frame. 2.

FIG. 13 and 14 show an embodiment of a double closed locking joint 4, which connects the middle part 3 with the lower frame 1 and the upper frame 2. The design of the double closed locking joint comprises the same elements as the solution described in the previous examples, but on the vertical rib 1.1 of the lower frame 1 and on the vertical rib 2.1 of the upper frame 2, two first locking parts 4.1 are formed, comprising a recess 4.11 and a protruding part 4.12. On the joined middle part 3, two second locking parts 4.2 are formed on top of each other on the lower circumference 3.1 and on the upper circumference 3.1, into which the two first locking parts 4.1 are inserted. If the rectangular combi box contains on each side two double locks on 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. This lock joint design is especially suitable for larger combi boxes. with a higher permissible load.

FIG. 15 and 16 show an embodiment of a double open locking joint 4, which connects the middle part 3 to the lower frame 1 and to the upper frame 2.1. Structurally, it is the same solution of the locking joint as described for the exemplary embodiments in FIG. 13 and 14. The difference of this locking joint 4 is that a cross section 6 is formed from the second locking part 4.2 towards the open side of the middle part 3 and also a cross section 7 is formed between the two second locking parts 4.2 placed above each other. 7 facilitate the insertion of the second locking parts 4.2 into the first locking parts 4.1 on the lower frame 1 and on the upper frame 2.

In FIG. 17 and 18 show a rectangular combi box 10 consisting of a middle part 3 and a lower frame and an upper frame 2, the middle part 3 being connected to the lower frame and the upper frame 2 by a single open locking joint 4. The design of the single open locking joint is identical to the exemplary embodiment described and illustrated e.g. in FIG. 7 and 9. However, one shorter side of the connected parts 1, 2 and 3 forms an open side 8. This solution is particularly suitable for storing goods on shelves, where the open side 8 provides access to the storage of goods. The open side 8 can also be formed on two opposite shorter sides or on an adjacent shorter and longer side and the like. To strengthen the strength of the joined parts 1, 2 and 3, these parts are still welded together at points 12

Although several variants of the connection of the lower frame 1 and the upper frame 2 to the middle part 3 of the combi box have been described and illustrated, other various combinations are not excluded, e.g. one combi box will be connected on the lower frame to the middle part by a double closed locking joint and on the upper frame by a single open locking joint, etc. Additional strengthening of the strength of the connected parts, e.g. by welding or mechanical connection
