Description:
A method for producing a luggage shell and a luggage shell

Technical field

The present invention relates to a method for producing a luggage shell and a luggage shell produced by this method. For the purposes of the present invention, within the meaning of the International Patent Classification in Section A45C, the term "luggage" is intended to include containers for personal belongings for traveling, such as travel bags and suitcases, trunks. Wallets, money bags, pocket-books, key cases, piggy banks are also included in the subclass of this class. Furthermore, these are soft luggage types as ladies' and beach handbags, ladies' theater clutch purses, evening clutch party handbags for women, business ladies' and men's briefcases, attach6 cases, shopping bags, shoe bags. Furthermore, these are solid or semi-solid luggage types as suitcases, traveling baskets, bags, backpacks and all special cases and boxes in the subclass A45C 11 to 15. The invention falls within the field of human necessities.

Background of the invention

Technologies for the production of handbags and the like are known in the present state of the art, in which individual shell parts are cut from the treated leather, leatherette or textile sheets, which are then stitched to the prescribed shapes. By attaching the handles and closing elements, handbags and similar products are produced after final surface treatments. Products such as shopping bags and handbags made of wood are also known. They are made of thicker wood panels incorporated into other materials or are made of veneer panels or wood slat segments suitably bonded with fabric or leather. In most cases, the individual parts are made as flat sheets. Round edges are made by carving mortising or milling.

The above-mentioned deficiencies have provided, in part or in full, the possibility of solving this problem by suitable technical means where a vacuum pressing system is used.

As a result, a method for producing a luggage shell and a luggage shell in the broadest sense according to the present invention is described below.

Summary of the invention

The above-mentioned deficiencies are substantially eliminated by the method for producing a luggage shell and the resulting product which is luggage according to the present invention. The essence for producing a luggage shell consists in that part or the whole luggage shell is produced by vacuum pressing technology in such a way that natural materials with adhesive and / or binder deposited on their surface are laid in multiple layers in the mold of parts or the whole luggage. The mold may be metal or wooden, whole or divisible. Advantageously, the mutual layering is transverse to increase the rigidity of the resulting product. The mold of parts or the whole luggage with the stacked natural materials is covered with a silicone or rubber vacuum foil and placed on a work surface in a vacuum press. By creating and applying vacuum, natural materials adhere to the mold surface of parts or the whole luggage and perfectly follow the shape of the mold, in the case of cold pressing, only the curing process of the adhesive is left to act over time, result of which is a part or all of the luggage shell. In the case of hot pressing, the curing process of the adhesive and / or binder is accelerated by the thermal action of the heated mold or environment. By this method, rigid but also flexible shells of individual products are produced.

After removal from the mold and after the curing process of the adhesive and / or binder, the surface treatment follows with one or a combination of grinding, polishing and varnishing technologies, e.g. by glossy, matt and semi-matt elastic varnishes, in the production of this luggage shell, wood veneers of different kinds of wood species or stone veneers or wood or leaves of trees and shrubs or grasses and flowers or hay or straw may be considered to be natural materials. When layering natural materials, they can be combined with inorganic materials or metals or fabrics or leather to form surface patterns or reliefs when interposed between layers of natural materials. In the combination of veneer and textile, e.g. silk, elastic and flexural properties of the individual parts are achieved. After subsequent removal from the mold, the edges of the shell are glued together and the inner space of the shell is provided with a lining and / or an insulating sound-deadening layer.

The subject matter of the present invention is also the luggage shell made by the above- described method. The baggage shell consists of at least one piece. The parts consist of multiple layers, mainly of natural materials, which are based on veneer. The parts are vacuum-molded and glued with physically curing adhesive. The luggage shell may also have a differentiated wall thickness, thereby providing a flexible surface with a fixed perimeter. In addition to natural materials, they may be composed of layers of inorganic materials or metals or fabrics or leather. The natural materials of the parts are wood veneers or stone veneers or wood or leaves of trees and shrubs or grasses and flowers or hay or straw. The advantages of the method for producing a luggage shell and a luggage shell produced by this method according to the invention are evident from the effects they exert on the outside. In general, the originality of the present solution lies in the fact that it is produced from environmentally pure raw materials and is fully recyclable. It keeps its shape. Each product is original because there are not two identical products of one type except concrete with metal surface. They do not deform after wetting. They have higher variability in the creation of different surfaces compared to leather, artificial leather, in which blind printing, printing, grinding and the like are used. They are not made of animal skins. They create an inner space for storing things that don't crumble or get damaged. If locked, the luggage cannot be opened by cutting it with a knife and a sharp object. The inner space of luggage is well arranged and things stored there are easy to find. In the event of an attack, the luggage can be used as a self-defense device. The variety of product surfaces is achieved by gluing an attractive veneer pattern as a final layer or by applying a metal layer such as gold coating, silver coating and the like, concrete, stone, leaves of trees and shrubs, grass and flowers, hay and straw and the like. Further advantage is the formation of shells of products, such as handbags by layering leaves of trees. The process is similar to layering and pressing veneer. In the case of the use of leaves of trees of different kinds of wood species, it is suitable to use at least one layer of textile when layering.

Examples of embodiment

It is to be understood that the individual embodiments of the invention are presented for illustration and not as a limitation of the technical solutions. Those skilled in the art will find out or be able to ascertain by using no more than routine experimentation many equivalents to specific embodiments of the invention. Such equivalents will also fall within the scope of the following claims.

It cannot be a problem for those skilled in the art to optimally design the technological parameters of the production method and the selection of used materials, therefore these features have not been solved in detail.

Example 1

In this example of a particular embodiment of the invention, a method for producing a luggage shell is described, in this case a handbag, which is shown in FIG. 1. In this case, the handbag will have two side faces and a sheath. These parts of the luggage are made by cold vacuum pressing in such a way that natural materials with adhesive applied to their surfaces are laid in multiple layers on the molds of the individual parts of the luggage. In the alternative of hot pressing, the curing process of the adhesive is accelerated by the thermal action of the heated molds or heated environment. In another alternative, a binder may be used. The molds are metal, alternatively wooden and indivisible. The mutual layering of veneers is transverse; alternatively by using the inserted fabric it is longitudinal. The molds of the luggage parts with the laid natural materials are placed in a vacuum press. By creating and applying a vacuum, natural materials adhere to the mold surface and perfectly follow the shape of the molds. The adhesive curing process is then allowed to act over time, resulting in parts of the luggage shell.

After removal from the molds and after the curing process of the adhesive, the surface is treated by varnishing with flexible lacquers. Alternatively, grinding or polishing follows. After removal from the molds, the edges of the shell parts are glued together and the inner space of the shell is provided with an insulating sound-deadening layer and lining.

In the production of this luggage shell, wood veneers of different kinds of wood species have been used as natural materials. Alternatively, stone veneers, wood, leaves of trees and shrubs, grasses and flowers, hay, straw, but also inorganic materials, metals, fabrics, leather to create surface patterns or reliefs are used in combinations, if they are interposed between layers of natural materials. Also combination of veneer and textile such as silk is suitable.

Example 2

In this example of a particular embodiment of the invention, a baggage shell produced by the vacuum pressing method according to this invention is described. In this case, the handbag will have two side faces and a sheath. The baggage shell consists of three parts consisting of multiple layers of at least natural veneer-based materials, vacuum- molded and glued with physically curing adhesive.

Alternatively, the handbag shell comprises in addition to natural materials also inorganic materials such as glass balls or metals such as steel rods, as shown in FIG. 2 and it represents the surface of a handbag shell with spatial modeling. Alternatively, fabric or leather in the form of an inlay is used for the surface treatment, as shown in FIG. 3. The natural materials of the shell parts are also wood veneers or stone veneers or wood or leaves of trees and shrubs or grasses and flowers or hay or straw, as shown in FIG. 4.
