Definitions
- the invention relates to a slipper with a foot pocket which receives the foot and is designed in the manner of a stocking and a sole part which reinforces the sole surface thereof.
- slippers of this type have long been commercially available under the name "slippers".
- the well-known hut shoes usually have a knitted foot pocket, the sole surface of which is covered and reinforced on the outside by a leather blank.
- the leather blank is along its raised edge, i.e. above the outsole, sewn with the knitted foot pocket.
- This well-known slipper is easy to put on due to the flexibility and deformability of the foot pocket and adapts perfectly to different foot sizes and shapes.
- the wearing comfort is insufficient due to the lack of foot support and the poor hold of the mesh of the foot pocket.
- the foot pocket expands extremely quickly after only a short use, and the all-round seam between the foot pocket and the sole part is exposed to extreme loads.
- the invention has for its object to design the slipper of the type mentioned so that it is very comfortable to wear.
- the sole part has a molded sole made of foam, the molded sole being adapted to the shape of the foot and provided with a molded footbed; that the footbed side of the molded sole is covered with at least one layer of textile material, in particular a nonwoven fabric; and that the molded sole is installed in the foot pocket and is connected to the inside of the sole surface of the foot pocket by material lamination on its side facing away from the footbed.
- the invention therefore combines in the new slipper a wearing comfort previously only achievable with normal running shoes or sports shoes and a large-area support of the respective sole area with simple manufacture and a long service life.
- the molded sole is placed in the foot pocket and firmly connected to it on the inside of the sole surface.
- the connections are made using high-frequency technology.
- at least one layer of plastic is provided on the side of the molded sole facing away from the footbed, which layer forms the connecting material between the molded sole and the foot pocket. Before melting, this layer can be a thin plastic film blank, preferably made of polyurethane, which is installed between the sole part and the foot pocket.
- the foil blank can be laminated on both sides by the action of high-frequency energy and establish the connection between the sole part and the foot pocket.
- the molded sole is preferably made of thermoplastic foam.
- An open-pore foam is particularly suitable, which is permeable to air, compliant and nevertheless dimensionally stable.
- the at least one molded sole layer is made of textile material as a nonwoven and is provided with an antiperspirant finish.
- the textile material can be provided with an antibacterial and / or antifungal finish.
- the foot pocket itself preferably consists of a knitted fabric or a natural yarn, which may contain an admixture of a plastic.
- the tread of the foot pocket facing away from the molded sole is at least partially provided with applications which can transmit pressure forces from the slipper to the floor surface.
- the adhesion of such applications to the foot pocket can be enhanced in a further development of the invention in that the applications are connected both to the foot pocket and to the molded sole.
- the applications can be laminated using the high-frequency technology through the foot pocket material with the adjacent interface of the molded sole.
- the applications consist of a plastic which increases the grip of the tread. This results in a slipper that is non-slip on the usual floor coverings.
- a band-shaped polymer, in particular polyethylene, in which a blowing agent is incorporated, is foamed by the application of heat.
- the foaming can take place when leaving an extrusion tool or at a suitably designed heating station with the supply of heat.
- the foamed material is then inserted into a mold which forms the warm foam into the molded sole and thereby removes heat from the foam, ie cools the molded sole.
- the mold sole is cleaned and burrs removed.
- the molded sole in the footbed area is covered with textile material, for example a nonwoven layer or an inner terry cloth, and firmly connected to the textile material by high-frequency technology.
- the covered molded sole is provided with ventilation holes, for example with the aid of a suitable punching device.
- the sock-like foot pocket put on the molded sole and connected to the molded sole by high-frequency lamination on the side facing away from the footbed side.
- prefabricated applications are again attached to the tread of the foot pocket facing away from the molded sole by HF technology. These applications can have the shape of a continuous outsole, which can optionally also be pulled up over the rear heel section and the toe area of the slipper.
- the subject of the invention has numerous applications. On the one hand, as a slipper, it has unprecedented wearing comfort and offers excellent traction, especially on suitable applications, even on smooth floor surfaces; on the other hand, the foot is always free of constrictions and potential pressure points, since the foot above the footbed is only enclosed by the stocking-like foot pocket. The sensitive toes and any protruding and pressure-sensitive foot bones and ankle parts are kept stress-free. As a result, the slipper according to the invention is particularly suitable as a replacement for shoes for foot injuries. Since the new slipper is relatively stiff only in the area of the molded sole, but is otherwise flexible, it can be compressed in a relatively small space and, for example, in pockets of outerwear, windbreakers or the like. carry along.
- the new hosiery is z. B. the ideal footwear before and after sport with special shoes, such as ski boots, Iniese skates or ice skates.
- Another advantageous application for the new slipper is the use as a boat shoe.
- the new slipper offers sufficient grip for the foot and grip on smooth boat decks on the one hand, and temperature protection on the other hand, which is comparable to conventional shoes.
- Figure 1 is a sectional schematic exploded view of the manufacturing components of an embodiment of the invention before final connection.
- Figure 2 is a sectional view in the transverse direction through the finished slipper.
- Fig. 3 is a bottom view of the slipper of FIG. 2 with two applications increasing the traction of the tread in the heel and toe area.
- FIG. 1 shows the components of an embodiment of the slipper according to the invention.
- a foot pocket 1 is shown unnaturally widened in order to make the other installation components recognizable in a differentiated manner.
- the foot pocket 1 consists of a knitted fabric or fabric made of fluffy material which largely adapts to the circumferential shape of the molded sole 2 due to its elasticity and expands accordingly when a human foot is inserted.
- the molded sole 2 has a molded footbed 20, which can be designed according to orthopedic aspects and depending on the specific application of the slipper.
- the base material of the footbed 20 is preferably foam, in particular a thermoplastic foam, which can be laminated at least in certain areas by high-frequency technology.
- the footbed side of the molded sole 2 is laminated in the illustrated embodiment with a layer of textile material and provided with an antiperspirant, antibacterial and antifungal equipment.
- a thin film cut 3 made of polyurethane is installed between the molded sole and the inside of the sole surface 10 of the foot pocket 1.
- the material of the film cut 3 provides the connecting material when the inside surface of the foot pocket is laminated with the side 21 of the molded sole 2 facing away from the foot bed.
- the film 3 is laminated by pressing the inside surface of the sole pocket against the surface 21 of the molded sole 2 by supplying radio frequency energy.
- the connection material layer or layers have solidified, the inside of the sole surface of the foot pocket and the underside 21 of the molded sole 2 are firmly and permanently connected to one another.
- This connection is also moisture-resistant and machine-washable, so that in principle the entire slipper can be cleaned in the washing machine at the usual washing temperature.
- FIG. 2 shows schematically the inner layer 4 made of textile material, which is connected to the footbed side 20 of the molded sole 2.
- a plurality of ventilation holes 24 are arranged at a mutual distance, only two of which are shown in FIG. 2.
- the molded sole 2 is direct by high-frequency technology, i.e. without the thermoplastic intermediate layer, connected to the stocking-shaped foot pocket 1.
- the top 12 of the foot pocket 1 spans the foot bed 20 of the built-in molded sole 2.
- the foot bed 20 ensures sufficient lateral support without constricting or constricting the foot in the particularly sensitive front toe section.
- the outline shape and height of the molded footbed 20 can be freely selected depending on the application. Under certain circumstances, the material of the molded sole can be adjusted relatively flexibly in order to Fold back slipper according to the invention if necessary and thereby better to accommodate in a bag.
- the tread 11 of the foot pocket 1 facing away from the molded sole 2 is provided with applications 13 and 14 in the exemplary embodiment shown in FIG. 3.
- the applications are connected to the textile material of the foot pocket by high-frequency lamination.
- the applications 13 and 14 have a special coating which increases the traction in the area of the tread.
- a continuous outsole can be laminated onto the underside 11 of the foot pocket. The continuous outsole can also be pulled up in the heel area 15 of the foot pocket and in the front up to the toe area in order to improve walking comfort.
- the molded sole 2 can have a multilayer structure and, on the side facing the foot, can be made of an open-pore plastic that enables free air exchange. It is essential that the material in the transition area between the molded sole 2 and the inside of the sole surface of the foot pocket 1 can be applied by high-frequency lamination in order to firmly connect the foot pocket in the sole region to the molded sole.
