Definitions

  • the invention relates to a method for producing an item of luggage according to the preamble of claim 1.
  • the invention further relates to an item of luggage according to the preamble of claim 1 and an attachment part for such an item of luggage.
  • Suitcases in particular hard-shell suitcases with an outer skin made of at least partially solid material, but also cases with an outer skin made of softer, often textile material, are typically composed of several components, a rough distinction being made between the outer skin and various attachments.
  • cases are classically equipped with various add-on parts, such as wheels, pull-out bars, side handles or other functional elements that are subject to greater stress in use.
  • add-on parts consist of several components, in particular components which are attached to the outer skin and those which are attached outside the outer skin and which are connected to one another.
  • the outer skin is usually clamped between an inner and an outer plastic part (together: conventional attachment), and the two plastic parts are connected by means of screws or rivets, the screws being guided through holes in the outer skin.
  • the outer plastic part is, for example, the wheel housing.
  • the inner plastic part for example a counterpart to the outer plastic part, is absolutely necessary for the strength of the conventional construction, so that the forces acting on the opening in the outer skin do not load directly and lead to its breakage, but rather so that the forces acting on the screw connection are better be distributed over larger areas of the outer skin.
  • the outer skin and / or the add-on parts are mostly made of plastic, but can also be made of metal such as aluminum, carbon and the like.
  • the advantage of screws is that the items of luggage can also be manufactured by relatively untrained personnel and without special devices and machines.
  • the outer skin is also necessarily weakened at these points by the holes for the screws, and the round hole for the screw also creates a point of maximum stress, i.e. a point at which the pressure or tension exerted by external forces acts as stress in the component concentrated.
  • the hole in the outer skin or the large difference in strength between the screw and the outer skin creates, so to speak, a "predetermined breaking point" in the outer skin as well as in the attachment structure. If an attachment is held by 4 screws, for example, then the entire acting load is concentrated on those 4 screw points. The tension on the outer skin is also concentrated around those 4 openings that are absolutely necessary for the screws.
  • the US 9 681 717 B2 shows a foldable case made of flexible material, i.e. without an outer skin made of essentially solid material, and provides in the description the possible theoretical possibility of welding, screwing or riveting the inner part and outer part, i.e. no welding of attachments and outer skin, but welding two components of a conventional attachment with each other.
  • the flexible material is clamped between the inner part and the outer part and the inner part is provided in the form of a plate which is covered by the inner lining.
  • screws or rivets would possibly be replaced by welding, without eliminating the specific disadvantages of conventional connection methods and without optimizing the outer part and outer skin for the connection method, such as inner part, inner cover, and thus high weight and high costs remain.
  • the flexible outer skin of the case would still have to have openings (and thus weak points and predetermined breaking points) through which the inner part and outer part can come into contact with one another in order to be able to be welded.
  • the conventional add-on parts are completely retained here, only the possibility of different connection methods between the inner and outer parts is provided.
  • the welding of the inner and outer parts via openings in the flexible fabric skin of the case offers hardly any advantages compared to the screw connection, with the disadvantage that the welding is no longer detachable and therefore the outer part can no longer be replaced.
  • the object of the invention is to create a manufacturing method for a piece of luggage and such a piece of luggage, with which the most cost-effective, quick and automated production of a piece of luggage with the lowest possible weight and high strength results.
  • the interior of the item of luggage should be usable as undisturbed as possible and with maximum volume. Disadvantages of known methods and items of luggage are to be prevented or at least reduced.
  • the object according to the invention is achieved by the features of the characterizing part of claim 1 and by an item of luggage according to the characterizing part of claim 8.
  • the cohesive connection of the add-on parts with the outer skin according to the invention offers considerable advantages.
  • the add-on parts are connected directly to the outer skin without internal elements.
  • the finished piece of luggage is thus produced without screws and without an inner element.
  • the material connection is typically not made at individual points, but along lines or surfaces.
  • the connection location can be selected so that it is optimal for strength, appearance and the process. Since the connection does not distribute the forces to individual points, but along lines or entire surfaces, the connection between the outer skin and the attachment is much more even and stronger, making it more suitable for absorbing impacts and forces and distributing them more evenly in the component.
  • the attachment is at least partially provided on the side facing the outer skin with a complementary surface corresponding to the surface of the outer skin at the intended position.
  • “Complementary” surfaces are understood here to mean surfaces which, after the joining process to produce the bonded connection, nestle against one another at least in some areas. How much the two surfaces adapt to each other depends on the type of connection selected. In the case of adhesive connections, for example, the largest possible adhesive surface with a roughened surface is desired, so it is positive if the largest possible areas of the attachment and shell are essentially aligned with one another, albeit roughened.
  • Another advantage is that the outer skin appears completely smooth, uninterrupted and undisturbed on the inside no interior cladding is necessary anymore. This also reduces costs and weight and leads to a more attractive interior of the item of luggage.
  • the material connection by means of plastic welding is particularly advantageous, since relatively low investment costs have to be expended for this.
  • Both the outer skin and the attachment can have a perfect appearance after the welding process.
  • Other welding techniques such as vibration welding or laser welding can achieve similar results with a higher degree of automation, but also with higher investment costs.
  • the attachments must be shaped appropriately for the welding process.
  • elevations or projections are preferably provided on the surface to be welded, which are melted, for example, by rapid friction of the components and thus establish the material connection.
  • the add-on parts themselves can be manufactured, for example, using an injection molding process; metal elements and the like can also be overmolded in order to ensure special functions.
  • An alternative form of the integral connection of add-on parts and outer skin can be done by directly overmolding (overmolding) the add-on parts on the outer skin.
  • directly overmolding overmolding
  • the add-on parts are produced directly on the outer skin by injecting molten plastic directly onto the outer skin, which is placed in an injection mold, and then hardening it.
  • gluing Another possible form of material connection is gluing.
  • add-on parts could also be materially connected to the outer skin by gluing.
  • Gluing has various process-related disadvantages compared to welding or overmolding.
  • an attachment could be welded at one point and glued at another point inaccessible to the welding device.
  • Conventional wheel housings or holders for pull-out rods are typically composed of several components (inner elements, outer elements, screws) for suitcases.
  • the outer skin of the item of luggage must at least be provided with holes for screws, but often a part of the wheel housing also protrudes into the outer skin in such a way that it must have large openings for the inlet of these wheel housings into the interior of the luggage.
  • openings must be at least as large as the pull-out rods.
  • the inner element and the outer element overlap the openings and holes in the outer skin with a small margin in order to compensate for possible tolerances; otherwise the Attachments kept quite compact.
  • the goals of this construction are rather compact dimensions and to minimize the negative effects of the screw and openings on the strength of the outer skin and the attachments.
  • the wheel itself is attached to the wheel housing via bearings and axles. These bearings and axles are partially overmolded metal components. Since the force is only transmitted via the screw points anyway, a special stress-minimizing harmony between the outer skin and the wheel housing is not necessary.
  • the outer skin and attachment can only be in contact along a few points.
  • the outer or inner element is typically equipped with screw domes in which the screws are fixed. These screw domes must have a certain height in order to enable the screw to be adequately held.
  • add-on parts which were developed according to the invention are constructed and shaped completely differently.
  • the add-on parts can transfer forces to the outer skin over their entire contact surface.
  • the add-on parts do without an inner part.
  • compact shapes are more of a disadvantage, so the add-on parts are designed to be in contact with the outer skin over a large area.
  • Both the outer skin and the add-on parts ideally have rounded, stress-minimizing shapes and hug each other over a large area. Openings or holes in the outer skin are no longer necessary, the outer skin thus remains completely continuous and visually appealing from the inside and much more solid, since points with stress peaks are avoided.
  • the add-on parts no longer have devices for receiving screws (screw domes, screw holes and the like) but remain essentially flat and compact along the outer skin.
  • the material connection is produced by ultrasonic welding or vibration welding, small projections to be melted can be provided as part of the shape of the add-on parts, but also on the outer skin. These projections to be melted can be designed relatively freely, so that an optimal production or connection process is made possible.
  • the position, shape and number can be used according to the Vibration frequencies and other process parameters can be optimized.
  • the inner element is completely omitted in the production method and item of luggage according to the invention. It is no longer necessary or helpful, because the forces are transferred directly from the attachment to the outer skin via the material connection and there are no stress peaks. Bearings and axles can be made in one piece with the attachment and shaped in such a way that forces are diverted to minimize stress.
  • the production method according to the invention can also run in a fully automated or at least partially automated manner.
  • the investment costs are higher as a result, but the processes and tolerances can be precisely controlled, the unit costs are comparatively lower and more independent of wage costs.
  • a disadvantage of a fixed, non-releasable material connection between the outer skin and the attachment is that the attachment cannot be exchanged for possible repairs.
  • the add-on parts according to the invention can be shaped in such a way that they are designed for receiving and releasably fastening further components, which are then exchangeable.
  • this variant has the advantage that the outer skin remains without openings and holes, so that the forces are transmitted much better, and the outer skin is stronger because none Voltage peaks occur at holes.
  • the inside of the item of luggage also remains clean, the inner part is no longer necessary and the screws and inner part no longer need to be covered with fabric.
  • the construction becomes stronger overall and the weight of the item of luggage becomes lighter, the interior of the item of luggage becomes more appealing, but the detachable parts of the construction are replaceable.
  • Fig. 1 shows an item of luggage 1 consisting of two outer skins 1a, 1b, with various add-on parts 31 arranged thereon and connected to them, such as handle mounts 2, wheel housings 3, a stopper 4 or a holding device 5 for a pull-out rod.
  • Figures 2a and 2b show in sectional views comparatively different constructions of add-on parts 31, in this example wheel housing 3, the connection being made in a conventional manner by means of screws ( Fig. 2a ) and a way according to the invention ( Figure 2b ) he follows.
  • Fig. 2a shows an exemplary conventional attachment 31.
  • the exemplary conventional wheel housing 3 has an outer element 14a and an inner element 12, which clamp the outer skin 1a, 1b of the item of luggage 1 provided with openings 19 between them by screwing screws 11 from the inside into the screw domes 15 of the outer element 14a of the attachment 31 are set.
  • the outer element 14a and the inner element 12 each cover the openings 19 in the outer skin 1a, 1b by means of an overlap D. Due to the necessary height of the screw domes 15, the outer element 14a is only in a few points 20 on the outer skin 1a, 1b.
  • a cover 13 usually made of fabric, which visually conceals the screws 11 and the inner element 12.
  • the vertical axis 16a for the wheels can be produced as an overmolded metal part or in one piece with the outer element 14a.
  • Figure 2b shows an add-on part 31 according to the invention, which hugs the outer skin 1 a, 1 b along a comparatively large surface 10 and is attached there by the production method according to the invention.
  • No inner element and no inner cover are provided or necessary.
  • the exemplary wheel housing 3, 14b hugs the outer skin 1a, 1b harmoniously and without tension peaks, without interrupting it.
  • the outer skin 1a, 1b is therefore designed without holes and does not have to be covered by a cover in its interior.
  • the wheel housing 3 is made in one piece in this variant and integrates the axle 16b for the wheel already in a form that optimally absorbs forces and transfers them to the outer skin 1a, 1b over a large area. In this example, there is a hollow area between the outer skin and the attachment.
  • Fig. 3 shows a production method according to the invention of an item of luggage 1 by ultrasonic welding.
  • the add-on part 31 is placed on the outer skin 1a, 1b at the intended position.

  • Fig. 4 shows an alternative production method according to the invention as in FIG Fig. 3
  • the attachment 31 is not melted by vertical movements of the sonotrode 24, but rather by horizontal movements of the sonotrode 24 during vibration welding.
  • Fig. 5 shows an alternative production method according to the invention, but in this example the attachment 31 and / or the outer skin 1 a, 1 b is melted by the action of a laser 29.
  • the Figures 6 to 8 show manufacturing processes according to the invention corresponding to FIGS Figures 3 to 5 , with the difference that the add-on parts 31 contain an overmolded metal part 30 to improve functionality and / or strength.
  • Fig. 9 shows a production method according to the invention, the attachment 31 being produced directly on the outer skin 1a, 1b in the initially melted state.
  • the outer skin 1a, 1b is fixed on the inside at least in places with a fixing element 26 and an overmold 25 is pressed onto the outer skin 1a, 1b from the outside.
  • the melted plastic 27 is pressed through a channel 28 into a cavity in the overmolding mold 25, where it cools down and solidifies.
  • overmolding mold 25 and fixing element 26 are removed.
  • This process can be fully automated, which is associated with high investment costs.
  • Another disadvantage is that the add-on parts 31 are subject to various process-related restrictions in terms of their design.
  • Fig. 10 shows a conventional manufacturing method, wherein an outer element 14a and an inner element 12 of a wheel housing 3 are fixed by means of screws 11, which engage in screw domes 15, on the outer skin 1a, 1b with openings 19 provided for this purpose.
  • Fig. 11 shows an exemplary semi-automated production method according to the invention of an item of luggage 1 with the help of a prepared holding device 23.
  • the attachments 31 are placed in the positions provided for the attachments 31 in the holding device 23, then the outer skin 1a, 1b is placed and fixed by means of fixing elements 24.
  • the add-on parts 31 are now connected to the outer skin 1a, 1b by ultrasonic welding by means of sonotrodes 24, and then the successfully connected combination of outer skin 1a, 1b and add-on parts 31 is removed from the holding device 23 for further processing.
  • This method gets by with relatively low investment costs.
  • the individual manufacturing steps can be carried out by hand or by robot.
  • Figure 12a shows the assembly of a typical conventional attachment part 31, in this case a wheel housing 3, in an exploded view.
