Description

[0001] The present invention relates to a shoe with a textile insert which prevents socks worn on one foot inside the shoe from slipping.

[0002] Poorly fitting shoes often cause the wearer's foot to slip inside the shoe, particularly at the heel, especially when walking. In the worst case, the foot can even slip right out of the shoe. This movement, and the resulting friction, frequently leads to painful blisters. Additionally, socks worn inside the shoes can slip, especially the top of the shoe or the opening towards the toes. This is uncomfortable and can also cause skin irritation and blisters.

[0003] Furthermore, US patent 2,275,191 A discloses a protective insert for placement in the heel area of ​​a shoe, primarily intended to protect hosiery from damage and to increase wearing comfort. However, this insert offers insufficient protection against slippage.

[0004] Accordingly, the invention is based on the objective of describing a shoe in which slippage of a sock worn on the foot inside the shoe is prevented as efficiently as possible. This applies in particular to sneaker socks and / or footies.

[0005] The problem is solved by a shoe according to claim 1 and by the use of a textile insert in a shoe according to claim 10. Claims 2 to 9 further describe advantageous embodiments of the shoe according to the invention.

[0006] The shoe according to the invention has a textile insert on the inner wall of the heel counter of the shoe. The textile insert has a plurality of bristles, the bristles of which in turn have a ridge. The ridge is oriented such that movement, in particular of a foot and / or a sock, into the shoe occurs against the ridge, and movement, in particular of a foot and / or a sock, out of the shoe occurs with the ridge. Accordingly, the ridge defines, in particular, two directions. A first direction is defined at least partially, in particular completely, in the direction of the ridge, whereas a second direction is oriented at least partially, in particular completely, against the ridge. The first direction is thus, in particular, oriented from the sole to the end of the upper furthest from the sole, and / or the second direction, conversely, from the end of the upper furthest from the sole to the sole.If a movement, particularly of a foot and / or a sock, occurs in the first direction, this movement is not hindered by the textile insert. However, movement, particularly of a foot and / or a sock, in the second direction is hindered. It follows, in particular, that a foot can be pulled out of the shoe without hindrance from the insert, whereas this is hindered by other elements such as the vamp, Velcro fastener, and / or laces. When slipping into the shoe, and with every movement of the heel of the foot wearing a sock towards the sole of the shoe, the sock is shifted and / or stretched slightly towards the wearer's knee relative to the foot.

[0007] In a particularly advantageous development, the textile used is a woven fabric, especially velour or velvet. A woven fabric offers exceptional durability, particularly with regard to the orientation and / or arrangement of the bristles and the nap pattern. Velour or velvet are especially suitable due to their bristle length.

[0008] Advantageously, the textile insert and / or bristles have a height in the range of 0.5 to 4 mm, particularly in the range of 0.8 to 3 mm. With such a height of the insert and / or bristles, optimal effectiveness is achieved, especially with regard to preventing movement, particularly of the foot, in the second direction.

[0009] In a further advantageous embodiment, the textile insert has a length of at least 1 and / or up to 5 cm and / or a width of at least 2 and / or up to a maximum of 10 cm, in particular 2 to 7 cm, and in particular 2 to 5 cm, and / or an area of ​​at least 10 cm² and / or up to a maximum of 50 cm², in particular up to a maximum of 35 cm². In particular, the textile insert extends from the sole, or at least 1 cm above the sole, to the top edge of the heel or heel counter, or to at least 1 cm below the top edge of the heel or heel counter, or to the point where the heel extends most towards the toe of the shoe. Especially in the case of higher shoes or boots, it is by no means necessary for the insert to extend to the top edge of the shoe. In particular, the insert does not extend above the ankle of the wearer.The textile insert must be of a sufficient length, width, and / or area to effectively impede movement in the second direction. Specifically, the length of the textile insert is limited by the length of the shoe's heel counter, ensuring that it does not extend beyond it. Ideally, the textile insert is positioned and / or its length is chosen so that it begins directly below and / or between 1 and 10 mm below the top edge of the shoe's heel counter and ends directly above and / or between 1 and 10 mm above the shoe's footbed. The insert is positioned centrally within the heel area and / or at the heel counter. It is positioned so that it lies freely inside the shoe, with the bristles extending into the interior.It is not necessary for the entire stake to be exposed, but it is preferred if at least 75% of the stake is exposed.

[0010] Advantageously, the textile insert is attached to the shoe using an adhesive and / or sewn into the shoe.

[0011] With particular advantage, the textile application has a bristle density of 10 to 40, especially 20 to 30, bristles per cm². 2 A corresponding bristle density ensures that the bristles of the textile insert provide sufficient resistance to movement in the second direction, reliably preventing the sock from slipping.

[0012] A shoe according to one of the preceding claims, characterized in that the bristle has an orientation at an angle in the range of 5 to 45°, in particular 10 to 40°, in particular 20 to 30°, relative to a planar extent of the textile insert. In the case of a multifilament or several threads forming a bristle, the mean angle is measured. The bristle has, in particular, a maximum opening angle of 15°, in particular a maximum of 10°, between its different threads or filaments. The angle determines, in particular, the degree to which movement in the second direction is hindered.

[0013] Advantageously, particularly with regard to the permanent orientation of the line and / or bristles, the bristles are made of a thermoplastic material such as acrylonitrile butadiene styrene (ABS), polyamides (PA), polypropylene lactate (PLA), polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), polystyrene (PS), polyetheretherketone (PEEK), and / or polyvinyl chloride (PVC). The use of a thermoplastic material allows for the simple creation of the line pattern across the numerous bristles used in textile applications.

[0014] It is advantageous that the numerous bristles are aligned parallel to each other.

[0015] In a further advantageous embodiment, the multitude of bristles are each formed by threads with 10 to 50, in particular 20 to 40, filaments and / or the threads forming the bristles are not crimped and / or not textured and / or the textile insert is formed by warp threads, weft threads and pile threads and / or by 10 to 30 weft threads and / or 10 to 30 warp threads per cm and / or at least one weft thread, in particular 2 to 4 weft threads, is arranged between each pile thread for the formation of bristles and / or weft threads and warp threads are arranged transversely, in particular orthogonally, to each other, wherein the threads for the formation of the bristles are arranged either at least partially parallel, in particular parallel, to the weft threads or the warp threads.Appropriate textile inserts and / or bristles are particularly well suited with regard to preventing movement in the second direction and / or the stability of the bristles and / or the arrangement of the bristles and / or the stability and / or durability of the textile insert.

[0016] Advantageously, the multitude of bristles is produced by cutting loops of the pile threads, in particular the cutting takes place after a thermal treatment, by heating and cooling the textile, whereby a force is applied to the bristles during the treatment, which tilts them in the direction of the nap.

[0017] The advantageous developments described are not limited to the shoe according to the invention, but can also be applied to the use of a textile in a shoe described below.

[0018] The problem is also solved by using a textile with a large number of bristles in a shoe, particularly as described above, to prevent socks worn on a foot inside a shoe from slipping. The designs and advantageous features of the shoe can be applied to its use.

[0019] Further advantages and features of the invention will become apparent from the following description with reference to the accompanying figures. These figures show Fig. 1 Schematic representation of a textile insert with a line formed by the alignment between bristles and Fig. 2 Schematic representation of the formation of bristles by cutting loops of a pile thread. Fig. 3 Schematic representation of a shoe with textile insert in section and top view.

[0020] In Fig. Figure 1 schematically depicts a section of a textile insert 1 with a planar extent 2 and bristles 3. The bristles 3 are arranged parallel to each other along the planar extent 2. Furthermore, the bristles 3 are arranged at an angle 4 relative to the planar extent 2. The bristle on the left is shown with its three filaments. The angle is defined as the mean angle of the filaments. The bristles shown further to the right are simplified to a single thick bristle.

[0021] The arrangement of the bristles results in a line 5, the direction of which is indicated by an arrow in the drawing. This line also defines a first direction 6 and a second direction 7, likewise represented by arrows. If a foot and / or a sock (not shown) is moved along the first direction 5, it will not be hindered by the textile insert 1 or the bristles 3, even if it is in contact with them. However, if the foot and / or sock is moved along the second direction 7 past the bristles 3, the bristles 3 will offer resistance to the movement and thus impede it.

[0022] Fig. Figure 2 illustrates the formation of bristles 3 by cutting loops 8 of a pile thread 9. Here, the pile thread 9 is first inserted into a fabric with warp threads 10, and a loop 8 is formed at every third warp thread 10 and then cut open. Two bristles 3 are thus formed from each loop 8, particularly those lying directly next to each other and especially those aligned parallel to each other. The pile thread 9 therefore has segments 11. A bristle 3 is located at each end of each segment 11. In particular, two bristles 3 are formed after every third warp thread 9, especially those that are immediately adjacent.

[0023] Fig. Figure 3 shows a cross-section of a shoe with a textile insert (shown with a dashed line) in the inner heel area. The arrow indicates the line as shown in the Fig. 1.
