Description

【Technical field】
[0001]
The invention relates to a luggage product comprising two shell elements made of a plastic material according to the preamble of claim 1.
[Background Art]
[0002]
Such a bag product, such as a bag, suitcase or rucksack, consists of two shell elements of plastic material, which are interconnected by hinges along the edges of the free ends facing each other, A closing device, such as a lock, may be provided to hold these shells in the closed position.
[0003]
The above-mentioned luggage products are also made from fibrous materials, such as fibrous luggage products, which have the disadvantage that they are not robust and have a significant degree of sag. The advantage of textile material bag products is that they are lightweight and can be provided with pocket elements. Bag products made of ABS shell elements have the disadvantage that they are heavier than textile bag products. Furthermore, no additional pockets can be provided outside the suitcase. However, ABS plastic bag products have the advantage of being durable and resistant to sagging, compared to textile bag products.
DISCLOSURE OF THE INVENTION
[Problems to be solved by the invention]
[0004]
It is an object of the present invention to provide a luggage product comprising a plastic shell element which is light on the one hand and can be fitted with an upper pocket and on the other hand is durable and resistant to sagging.
[Means for Solving the Problems]
[0005]
This object is solved according to the invention by the features of claim 1.
[0006]
The invention has the advantage that the shell element is formed from a thin, flexible plastic material, at least one of the shell elements having an outwardly projecting perimeter defining an area, said perimeter being A zipper connects to the lid to form an outer pocket.
[0007]
Forming the shell element from a thin, flexible plastic material has the advantage that the luggage product is extremely lightweight and even lighter than comparable fiber luggage products. The flexibility of the plastic material allows a high degree of storage to be achieved, similar to bag products made of fiber material. At the same time, the high-strength but flexible plastic shell element is robust and hard to set to a considerable extent. In at least one of the shell elements, it is possible to provide at least one outwardly projecting perimeter defining an area, which is connected to the lid by a zipper to form an outer pocket. The thinness of the flexible plastic material allows the perimeter to be sewn to the zipper while the zipper is sewn to the lid. Thus, as an advantage, the outer pocket can be formed in a bag product comprising a plastic shell element in order to provide a partitioned storage space in the bag product.
[0008]
The plastic material is preferably made of a polycarbonate plate. Such a plastic plate can be deep drawn and has a high value of strength so that the luggage product can withstand a large load, especially when traveling by airplane. At the same time, the polycarbonate plate can be manufactured to be sufficiently thin, and the luggage product is on the one hand extremely lightweight and on the other hand sufficiently thin to be sewn.
[0009]
The polycarbonate plate is about 1.5 to 2.0 mm thick, preferably 1.6 mm.
[0010]
The lid may have a periphery facing the shell element. This peripheral portion can be connected to the side piece of the zipper.
[0011]
The projecting rim of the shell element and the rim of the lid are preferably rimmed by a rim, and the side pieces of the zipper are connected to the rim and the rim.
[0012]
In one particular preferred embodiment, the shell element is first configured as a molded part with a one-piece lid that is integrally molded, and then the molded part is separated along a parting line while the projecting peripheral edge Into a shell element with a section and, on the other hand, into a lid. This has the advantage that the shell element and the lid having a projecting rim can be manufactured in a single manufacturing step.
[0013]
The open point in the shell element, formed by separating the lid, can be closed by a bottom part having an outwardly projecting perimeter, which protruding edge is adjacent to the shell element. The perimeter, edging member, and one side piece of the zipper join together.
[0014]
In this connection, the projecting peripheral edge is preferably sewn to the edging member and to each side piece of at least one zipper.
[0015]
When sewn with a high strength thread or a strong knitting thread, the connection strength between the zipper and shell element and the lid and / or bottom part is such that the luggage product can withstand large loads without any damage Respectively.
[0016]
Preferably, the closure device for the shell element also comprises a zipper.
[0017]
The bag product and the outer pocket zipper can have two separately operable sliders.
[0018]
One embodiment of the present invention will be described below in detail with reference to the drawings.
BEST MODE FOR CARRYING OUT THE INVENTION
[0019]
The bag product shown in FIG. 1 has substantially the shape of an attache case having an outer pocket 6. This luggage product is composed of plastic shell elements 2, 4 which are connected by hinges 5 and are held in a closed position by a closing device consisting of a zipper 12. The lower shell element 2 is provided with a handle 10 for carrying this luggage product.
[0020]
The zipper 12 connecting the two shell elements 2, 4 can be provided with two sliders 36 which can be operated independently of one another.
[0021]
The plastic shell elements 2, 4 consist of a high-strength polycarbonate plate having a thickness of about 1.0 to 2.0 mm. A preferred material thickness is 1.6 mm.
[0022]
FIG. 2 shows a deep-drawn part 24 in which the upper shell element 4 and the lid 8 for the outer pocket are integrally formed. This molded part 24 is separated along the parting line 26, whereby the shell element 4 and the lid 8 are manufactured on the one hand.
[0023]
The molded part 4 defines a region of the outer pocket 6 and has a recessed periphery 28 projecting outwardly from the shell element 4. In order to give this rim a high stiffness, the rim is recessed relative to the surrounding base 29, as best seen in FIG. When producing a projecting perimeter as shown in FIG. 2, an open point is created in the shell element 4 that can be closed by the bottom part 22. The bottom part 22 is manufactured separately and has an outwardly projecting peripheral edge 30. The perimeter 30 and the perimeter 28 project in the same direction, as shown in FIG. 3, so that the back side of this bottom part 22 preferably forms substantially the same plane as the inner main surface of the shell element 4. Can be linked.
[0024]
It goes without saying that a plurality of outer pockets can be arranged outside the shell element 4. They can be arranged side by side or on the outer main surface of the shell element 4 or 6, one above the other. Alternatively, when the lid 8 forms two peripheral portions 32 projecting in opposite directions to each other, one can be arranged on one.
[0025]
In one alternative, not further illustrated, the molded part 24 can be manufactured integrally with the bottom portion 22 so that only one outwardly projecting peripheral edge 28 is formed in the molded part 24. In this case, you could probably omit the bottom separation. However, in this case, the lid 8 must be made separately.
[0026]
As can be seen from FIGS. 1 and 2, the shell elements 2, 4 have at their mutually facing ends 9 a peripheral bead 34 at a slight distance thereto, the beads being directed outwardly. It protrudes and makes the end 9 rigid like a frame. Between the peripheral bead 34 and the end 9 there remains a strip into which this end 9 is fitted and which receives the edging members 14 sewn to the side pieces of the zipper 12, respectively.
[0027]
As can best be seen from FIG. 3, the bottom portion 22 is in contact with the outwardly projecting rim 28 of the shell portion 4 by its outwardly projecting rim 30, and both edges 28, 30 are It is fitted into a peripheral edge member 18. The zipper 16 of the outer pocket 6 is sewn to the edging member 18 and the intervening edges 28 and 30 via the side piece 15. A seam is formed with a high-strength sewing thread or a knitting thread so as to realize a high-strength connecting portion capable of withstanding a large load of a bag product.
[0028]
The other side portion 17 of the zipper 16 of the outer pocket is sewn to the edging member 20 into which the peripheral portion 32 of the lid 8 is fitted. The lid 8 can also be articulated with the shell element 4 by means of hinges 7. The hinges 5, 7 are, for example, made of artificial leather material, each sewn to the shell element 2, 4 and the lid 8, and can be additionally riveted if necessary.
