Description

The utility model relates to devices that exercise physical load on the muscles of the lower extremities of a person during training of athletes involved in speed skating, skiing, cross-country running in athletics, soccer, during rehabilitation of patients after surgery on the lower extremities, in the treatment of cerebral palsy in children, when working in zero gravity, and can be used in sports, medicine, astronautics and other forms of human life, where physical load on the muscles of the lower extremities is required ESA.

A device for maintaining orthostatic stability is known, in which an elastic element is used that plays the role of artificial gravity to create an adequate load on the musculoskeletal system of a person.

(Aut. St. USSR 256164, А63В 23/00, B.I. 43, 1976).

However, such a device provides a short-term effect of the load on the human muscles and acts only on a certain group of back muscles and does not provide enough load on the lower limbs.

A well-known suit is the Vector exercise machine, which is a system of mobile weights that are individually oriented in a certain way relative to a specific group of body muscles (Lagutin AN, Athletic gymnastics. Kiev: Health, 1990, pp. 62-63) .

The disadvantage of this device is that the load is provided with the help of weights and only on a specific group of muscles on the musculoskeletal system of a person.

A device is known for training muscles, made in the form of clothing parts from elastic knitwear with interlocking, even looped columns of which are formed from inextensible threads, and odd ones are formed by loops, each of which contains inextensible and elastomeric threads, in which the looped columns are oriented in the transverse direction, and the details of the clothes are 10-32% smaller than the size of the parts of the body and a device for training muscles, made in the form of a suit.

(Russian Patent 2074546, А63В 21/065, B.I. 6, 1997).

However, such a device does not provide a constant power load along the muscles of the lower extremities, since the looped columns are oriented in the transverse direction and do not provide sufficient elasticity to the details of the clothes.

Known suit for work in zero gravity, made of knitted fabric, in which the details of the suit in the shoulders, hands, feet are made of inextensible knitwear, and the parts providing the load on the musculoskeletal system of a person are made of tensile knitwear consisting of elastic threads and filaments of ordinary extensibility, simultaneously knitted in loops, and the parts providing the load have linear dimensions of 5-40% less than the size of parts of the human body.

(Russian Patent 2060913, B64G 6/00, A62B 17/00, B.I. 15, 1996).

However, such a suit cannot provide a constant power load on the lower limbs, since the elasticity of the parts of the costume provides the power load, acting mainly on the muscles in the back, chest and waist, and the elasticity of the parts of the costume in the legs is minimal.

Closest to the device for training the lower extremities is a device for training the lower extremities made of a knitted fabric containing parts from inextensible knitwear and parts providing a load on the musculoskeletal system of a person, from tensile knitwear, in which the parts in the torso region are made of two parts : upper - from stretchable knitwear, lower - from inextensible knitwear, loops of which are oriented in the transverse direction, and details in the area of the legs - from knitwear, consisting of skull uyuschihsya through the loop 20-40 series of extensible and stretchable knitted loops which are oriented in the longitudinal direction and in the leg region has linear dimensions of parts to 8-20% less than their linear dimensions.

(Russian Patent 2207176, А63В 21/065, 23/04, В64G 6/00, B.I. 18, 2003).

However, such a suit cannot provide a constant force load on the upper part of the legs, since the elasticity of the parts of the costume provides the power load, acting mainly on the muscles in the back, chest and waist, and the elasticity of the parts of the costume in the legs is minimal.

The objective of the utility model is to create a new device for training the muscles of the lower extremities of the musculoskeletal system of a person, providing a load on the muscles of the lower extremities.

When using the proposed device for training the lower extremities, the following technical result is obtained: providing a constant power load on the muscles of the lower extremities.

The technical result is achieved in that the device for training the lower extremities is made of a knitted fabric containing parts from inextensible knitwear and parts providing a load on the musculoskeletal system of a person, from tensile knitwear in which the parts in the torso region are made of two parts: upper - from stretch knitwear, the bottom - from inextensible knitwear, the loops of which are oriented in the transverse direction, and the details in the area of the legs - from knitwear, consisting of alternating after 20-40 p rows of inextensible and extensible knitwear, the loops of which are oriented in the longitudinal direction, and the parts in the leg area are linear in size 8-20% less than their linear dimensions and contain additional parts in the leg area made of simultaneously knitted inextensible and elastomeric threads, In the form of weaving, 1 + 1 erasers are located across the width of the knitwear, alternating through 10-15 looped posts.

The implementation of the parts of the device in the torso of two parts allows you to hold it on the person’s body using the upper section of stretchable knitwear, and part of the inextensible knitwear serves to fasten the parts in the leg area.

Orientation of the hinge columns in the torso region in the upper part of stretchable knitwear and in the lower part of inextensible knitwear in the transverse direction allows to reduce the force load on the human torso in the upper part and increase the extensibility of the lower part of inextensible knitwear due to the pulls between the loops.

The use of knitwear for the manufacture of device parts in the leg area, consisting of alternating through 20-40 looped rows of inextensible and extensible knitwear, in which the loops are oriented in the longitudinal direction, provides a constant power load.

Reducing the alternation of rows of less than 20 during operation leads to a rapid wear of the device parts, since the strength decreases at the places where the rows transition from inextensible knitwear to rows from tensile knitwear.

An increase in the alternation of rows of more than 40 reduces the elasticity of the parts of the device, which makes it difficult to create additional load on the muscles of the lower extremities.

Orientation of the loop structure along the loop columns in the manufacture of device parts in the legs allows you to increase the load on the muscles of the lower extremities during operation.

Reducing the linear dimensions of the parts of the device in the area of the legs less than 8% of their sizes reduces the elasticity of the parts and does not create an additional constant load on the lower limbs.

Reducing the linear dimensions of the parts of the device in the area of the legs more than 20% of their sizes reduces the strength of the parts during operation and leads to rapid wear.

The use of additional parts in the form of tesami allows you to increase the power load on the leg muscles.

The use of 1 + 1 eraser weaving in the manufacture of braid for additional load of the lower extremities allows to increase the power load on the muscles of the lower extremities in the longitudinal direction and to reduce the twist of the braid along the looped column.

Alternating the arrangement of additional parts in the form of ribbons in less than 10 looped rows degrades the quality of the connection of the braid and knitwear.

Alternating the arrangement of additional parts in the form of braces over more than 15 looped rows reduces the power load on the legs.

Knitting at the same time inextensible and elastomeric threads in the manufacture of an additional section allows you to get elastic knitwear with high elongation.

The manufacture of a device for training the lower limbs in the form of trousers can improve comfort during operation and quickly change the elasticity of its parts with an increase in constant power load.

In FIG. there is presented a device for training the lower limbs in the form of trousers, consisting of a torso part 1 containing the upper part of an extensible knitwear 2 and the lower part of an inextensible knitwear 3, and parts in the area of legs 4, consisting of knitwear, in which rows 5 of inextensible knitwear alternate with rows 6 of stretchable knitwear and contains additional details of elastic knitwear in the form of elastic ribbons 7 interlacing eraser 1 + 1.

Knitwear for the upper part of the torso, consisting of stretchable knitwear, is made on an Interlock class 18-22 circular knitting machine by simultaneously knitting inextensible threads under a tension of 0.50-1.4 N and elastomeric under a tension of 1.0-2.0 N and the depth of stopping 2.8-4.5 mm. Inextensible knitwear for the lower part of the device is made on the same knitting machine with a cupping depth of 2.0-3.4 mm and a thread tension of 0.8-2.0 N.

Details in the area of the legs are made on a hosiery machine by switching the yarn feeders, one of which is tucked with inextensible thread, and the other two, one of which is elastomeric, after 20-40 rows of knitting. The tension of the inextensible thread is 1.0-1.5 N, and the elastomeric -2.5-3.0 N with a stop depth of 1.8-2.4 mm. Parts are made 8-20% smaller than the linear dimensions of the human legs. Additional details in the form of webs with 1 + 1 weaving are made on a class 10 flat-woven machine by simultaneously knitting inextensible and elastomeric threads with a stop depth of 1.9 mm. Finished parts of the device are sewn on an Overlock sewing machine, and additional parts are oriented in the longitudinal direction and are located along the width of the knit, alternating through 10-15 stitch stitches in the leg area to stitch rows made of inextensible knit. When connecting with knitwear, elastic braids stretch and sew in the stretched state.

During operation, the device is worn on the human body so that tension is created in the leg area, the stretched elements of loops of elastomeric threads of stretchable knitwear exert pressure on the leg muscles. Resisting this pressure, the muscles are under constant power load. The presence of additional details in the form of tesem creates an additional constant power load on the leg muscles when running or walking.
