Description

Field of the invention

[0001] The present invention belongs to the field of socks, particularly to the field of socks for special use, such as together with specialized footwear. The invention relates to a sport climbing sock for wearing inside a sport climbing shoe and a method for manufacturing said sport climbing sock.Background of the invention and the technical problem

[0002] Climbing is an activity for ascending a steep topographical object that can range from the world's tallest mountains to small boulders. Climbing is usually a type of recreation activity, however, it can be also for competition, or construction and military operations. Climbing is done indoors and outdoors, on natural surfaces and on artificial surfaces, such as climbing walls. For sport climbing, the climber uses sport climbing shoes, which are a specialized type of footwear having a tight fit, an asymmetrical downturn, and a sticky rubber sole with an extended rubber rand to the heel and the toe. The foot in a sport climbing shoe has a distinctly unnatural position. The foot is in a position that allows the force from the toe of the shoe to be transmitted throughout the entire foot. For example, if only a 1-2mm surface area on the toe of the shoe is used for stepping, the shoe must still hold the entire foot in the desired position and provide support.

[0003] Normal socks are made to improve the comfort and hygiene of the feet. They are accordingly thick, elastic, and made of materials that are friendly to the foot. A normal sock in sport climbing shoes does not function properly because: it does not hold the foot in the climbing position, it is too thick and not resistant, in extremely tight climbing shoes, wrinkles are formed that cause chafing and do not allow the use of climbing shoes, and the materials do not provide adequate friction between the sock and the shoe.

[0004] Consequently, it is customary for climbers to be barefoot in climbing shoes. The sensations, i.e. the communication between the rock and the climber through the footwear, are thus better.

[0005] With the development and increased popularity of indoor climbing, the use of climbing shoes has changed a lot, and this has led to the need for special socks made for climbing shoes. The technical problem addressed by the present invention is thus design of socks that will meet the specific needs of climbers and keep the foot in an optimal position for climbing.Prior art

[0006] Patent application US2024032610A1 describes a method of producing a double-layered sock with a cushion patch positioned between an external and an internal layer of yarn or fabric is provided. The method comprises the external layer over the internal layer of a tubular lay flat fabric. The method also comprises attaching a first polymer cushion patch to the external or internal layer about two inches from one end and a step of attaching a second polymer cushion patch to the external layer about five inches from the first cushion patch. After drawing the external layer over the internal layer, the cushion patch is encased inside the sock. The cushion patch has a honeycomb grid pattern and includes one or two areas of high compression having larger hexagonal cells designed to distribute high compression impact away and throughout the cushion patch, thereby improving user comfort during walking or running. This differs significantly from the present invention and does not keep the foot in the desired position for sport climbing.

[0007] Patent application JP2010163712A discloses a sock including a fabric having a woven or knitted structure, wherein the fabric includes a filament A having a single fiber diameter of 10 to 1500 nm and a filament B having a single fiber diameter of more than 1500 nm. The webpage of the applicant of this application also discloses sport sock made from the same filament, however, there is no specific disclosure for climbing shoes. Further, the design of the sock differs from the present invention and does not position the foot in the position suitable for sport climbing.

[0008] Patent application CN106723414A relates to a quick-dry wear-resistant low-cut sock for mountaineering. The sock comprises an upper cylinder, an instep and a sole. The instep and the sole are internally rolled up and down to be a main body. The main body is of a cylindrical structure. A liner is disposed at the arch of the sole. A moisture exhaust strip is disposed between the main body and a toe, wherein said strip is weaved by bacteriostatic yarns added with thin fibers. This sock is not suitable for sport climbing and does not have the same design as the present invention.Description of the solution to the technical problem

[0009] The invention addresses the technical problem identified above and provides a sock for sport climbing, which is configured to keep the foot in a curved position, which is optimal for sport climbing. The technical problem is solved as defined in the independent claims, while preferred embodiments are defined in the dependent claims.

[0010] The essence of the invention is in that the sport climbing sock is divided into at least two parts, namely a first part is designed in three sections, wherein the first section is configured to cover the top of the toes from at least the nails of the toes, more preferably at least first knuckle of the toes, the second section is configured to cover the ball and the arch of the foot along the length of the foot and across at least a part of the width of the foot, preferably the entire width of the foot, and the third section is arranged to cover at least a part of a heel up to the Achilles tendon attachment point, preferably the whole heel at least up to the Achilles tendon attachment point, so that the first part as a whole covers at least a part of toes, a part of the sole of the foot and a part of the heel, and a second part designed to cover at least the bridge of the foot and the parts of the foot not covered by the first part, wherein the first part is made from a highly resistant rigid material and the second part may be made from a flexible material, such as polyamide and elastane. When the foot is placed in the basket at the front on the toes and the sock is pulled over the heel, the sock pushes the foot into a "climbing" position characteristic for its curved shape in which the toes are clearly downwards, the arch of the foot is emphasized and the heel is pushed towards the toes.

[0011] The first part must connect the toes and the heel and a part of the ball and the arch of the foot to ensure the above-mentioned position of the foot. In order to achieve this effect, the first part has to create a first section to surround the toes and a second section to surround the heel. The first section has to extend at least the nails of the toes, but can also be longer and cover toes as a whole. The third section has to end at least at the attachment of the Achilles tendon, but it can also end higher along the Achilles tendon, for example 1 to 3 cm above the attachment of the Achilles tendon. The first and the third sections are connected with the second section covering at least the ball and the arch of the foot along the length of the foot and across at least a part of the width of the foot, preferably the entire width of the foot.

[0012] In most preferred embodiments, a third part may be provided, wherein it is preferably designed as a narrow tape extending over a part of the instep and a part of the sole between the heel and the arch of the foot. This third part can be made with or from silicone-coated thread, which prevents the sock from sliding along the skin.

[0013] The sock may optionally further comprise an upper part embracing the ankle, which is on the inner surface configured to touch the skin of the user. For example, a fourth part forming a tab on the heel extending over at least a part of the Achilles tendon may be provided.

[0014] The first part can be knitted as a whole using 3D knitting technology known to the person skilled in the art.

[0015] The prefered materials for the first part are highly resistant rigid materials, such as polyester fibers with parameters: tenacity in the range from 4 to 5 N (tested or determined according to method JIS L 1013 8.5), elongation at break in the range from 20 to 40 % (tested or determined according to method JIS L 1013 8.5), boil shrinkage in the range from 1 to 3 % (tested or determined according to method JIS L 1013 8.18.1), and dryheat shrinkage in the range from 0.5 to 2% (tested or determined according to method JIS L 1013 8.18.2 at 150 °C).

[0016] Most preferably, the first part is made from ultra-fine polyester fiber having a diameter of 700 nm, commercially known as Nanofront. This material ensures that the first part exhibits exceptional non-slip grip on both the skin and the footwear. The fineness of the material can be in the range from 140 to 180 dtex, which can be determined with a method according to JIS L 1013 8.3).

[0017] The base of the sock described above is joined to the other parts by 3D knitting, i.e. without overlapping material or thickening, which will allow the wearing of a tight climbing shoe. Particularly, the whole sock is knitted in one step, wherein the program for the 3D knitting is designed to use different materials based on the part of the sport climbing sock it is knitting. Once knitting the first part, the highly resistant rigid material thread is used, wherein in the section overlapping with the second part the 3D knitting device uses both the rigid and the flexible threads to ensure proper transitions. In case the third is provided, the program is suitably designed to make a narrow tape extending over a part of the instep and a part of the sole between the heel and the arch of the foot and silicone-coated thread is used by the 3D knitting device.

[0018] The sport climbing sock as described above ensures that the foot is formed and kept in a "climbing" position characteristic for its curved shape in which the toes are clearly downwards, the arch of the foot is emphasized and the heel is pushed towards the toes. When used in sport climbing shoes, the sock acts complementary to the sport climbing shoe and allows the force from the toe of the shoe to be transmitted throughout the entire foot.Brief description of the drawings

[0019] The invention will be disclosed in further detail based on an exemplary embodiment and figure 1, which shows the sock for wearing inside a climbing shoe arranged to keep the foot in a curved position suitable for climbing.Detailed description of the invention
