Description

OVERALL SPECIAL APPOINTMENT WITH IMPROVED ERGONOMIC PROPERTIES.

The utility model relates to overalls, namely to overalls for working in especially cold conditions. Jumpsuit can also be used for winter active sports. The proposed new design allows to improve the ergonomic characteristics of special clothes, reduce heat loss during physiological and hygienic needs at low temperatures, and also provide convenience when making such movements as: raising and lowering arms, torso, squats.

Currently, to protect workers from low temperatures, various assortment units are used, which include sets consisting of a jacket and semi-overalls or trousers. The thermal insulation properties of clothing are largely determined by the mobility of the air enclosed in it. The closed construction of the overalls provides the greatest tightness when cold outside air penetrates into the clothing area, and is therefore more preferable to a set consisting of a jacket and semi-overalls or trousers, especially in the wind. However, at present, the jumpsuit has not received widespread use due to significant heat loss when it is necessary to fulfill physiological and hygienic needs at low temperatures, as well as due to insufficient freedom when making such movements as: raising and lowering arms, tilting the body, squats . The developed utility model has improved ergonomic properties and will reduce heat loss during physiological and hygienic needs at low temperatures, and provide greater convenience during various human movements in the workplace.

A set of combination protective clothing is known (Patent No. RU 86848 U1 class. A41D 13/00 from 09/20/2009). The set consists of a straight jacket with a hood and semi-overalls. In front of the jacket, it fastens with a central side clasp, which is covered by a protective strip passing to the hood. A stitched hood on a lining made of calico, adjustable in volume of the head with the help of a strap and textile fastener; a drawstring with elastic braid is inserted along the front cutout line. Two-seams are set-in sleeves, semi-overalls trousers are made with a detachable breast along the waist line and a stitched belt on the back with a zipper on the braid, overlapped by a codpiece.

The considered set causes a decrease in thermal insulation, because does not have sufficient tightness. Outside cold air enters the clothing area through the bottom of the jacket, which accordingly reduces the thermal resistance of clothes and worsens the thermal state of a person. The use of semi-overalls is due to operational difficulties and significant heat loss in the implementation of physiological needs. Also, when using this kit, there is a risk of catching on the protruding reinforcement elements at the bottom of the jacket, which can lead to an accident or injury at work.

Known work overalls (Patent No. US 8256023 B2 class. A41D 27/20 from 09/04/2012). The jumpsuit includes upper and lower parts. The upper and lower parts are connected along the waistline. At the top is a central clasp. Reflective tapes are located on the left and right side of the back. At the waistline is a belt with an elastic cord. The lower part of the jumpsuit is connected to the upper part along the waist line and includes a folding back part with a fastener on the “zipper” braid, on which there are two pockets and retroreflective tapes. The lower reclining part is in the shape of the letter “U”.

Known Armor heat-protective overalls (Patent No. RU 2474783 C1 class. F41H 1/00 from 02/10/2013). Armor-heat-protective overalls, including the left and right front parts of the legs, yoke, back with sidewalls of the back and the outer and inner parts of the sleeves sewn with front and rear longitudinal seams. Sleeves and trousers are equipped with cuffs with textile fasteners, zippers of the overalls are closed with trims with similar textile fasteners. The back of the legs is overlapped over the back and its sidewalls sewn along their lower edges. The back of the legs along the upper edge is equipped with a drawstring into which an elastic band is inserted with the exit of its ends, equipped with textile Velcro fasteners, to the front parts of the overalls.

The overalls in question have a number of disadvantages: designs with a hinged back do not provide sufficient freedom when raising arms, tilting the body and squats; in the area of knees and elbows, the anatomical features of a person are not taken into account when performing such movements as: bending, extension of arms and legs, squats; the absence of a hood does not allow working in an open area under adverse weather conditions.

Closest to the proposed utility model is a jumpsuit for climbers related to sportswear (Patent No. RU 2448621 C1 class. A41D 13/00 of 12.24.2010). The essence of the invention lies in the fact that in a jumpsuit for climbers, containing the upper part, consisting of a front with a central front zipper on the braid, a back, sleeves and a hood, connected by a stitched belt with a lower part consisting of front and rear parts of trousers with hinged back part, oval-shaped yoke and zipper on the braid between them, ventilation device, knee pads and elbow pieces. The ventilation device is located in the armpits in the form of an opening with a fastener on the braid “zipper” and a lining of mesh material. The stitched belt is made with elastic braid, the central zipper detachable on both sides of the “zipper” braid goes to the front of the trousers and the hood. The central fastener is closed by a wind-shelter, fastened with a Velcro textile fastener.

The zipper on the braid with two locks connecting the hinged back with the oval back yoke is closed by external and internal planks. Gusset in the middle and step seams of the trousers, reinforcing pad inside the step seams, a zipper on the bottom side seams, an elastic cord with a lock in the hem of the hem of the trousers. A stitched hood with a visor, one-piece with the upper front part of the hood, and an elastic cord with locks. The objective of the invention is to increase the protective properties and ease of use of overalls.

However, this jumpsuit has a number of disadvantages:

The design with a hinged back of the trousers uses a zipper on the braid that connects the hinged back to the yoke of the back. The fastening line of the fastener is oval. The zipper fastener creates an undesirable additional rigidity and thickness in this area. The impact of atmospheric phenomena, such as snow, low air temperatures, have a negative and sometimes devastating effect on the fastener, as Snow falling between the fastener links can cause breakage.

In the construction of the overalls, in the area of the knee and elbow, the anatomical features of a person in statics and dynamics are not taken into account.

The objective of the claimed technical solution is:

- ensuring quick removal of the product without heat loss for a person at low temperatures in the implementation of physiological and hygienic needs;

- providing additional freedom for a person with: torso and arms raised up and to the side, squats, flexion and extension of the arms, turns and tilts of the head;

- ensuring the prevention of engagement for protruding objects.

The essence of the claimed utility model is illustrated by drawings, where in FIG. 1 shows a general view of the overalls in front and from the back.

The claimed utility model of moderate volume, straight silhouette, with a shirt cover of the sleeve, with a central fastener on board on the “lightning” braid, which is protected by a four-button windproof strap 1 The product with a heating pad is designed for use in wintertime in harsh climatic conditions III- IV class.

Before the product is one-piece. In the lower part there are welt pockets with a zipper fastener, closed with a stitch strap 2 and patch pockets for tools with a valve for one button 3. In the area of the knees there are reinforcing anatomical overlays with tucks 4. A retroreflective (CB) tape is sewn on the front of the product. On the left side of the front is an internal patch pocket for documents.

The back of the overalls consists of two parts: the upper and lower. The upper part is flap-down, length up to the middle of the thigh 5, is fixed due to a stitched elastic belt in the region of the lower back 6. On the back there is a NE tape.

In the lateral seam at the bottom of the trousers, a “lightning” braid is sewn in, 23 cm long, protected by a stitch strip fastened with Velcro 15 tape.

In the upper part of the sleeves, at the bottom of the trousers there is a 50 mm wide NE. At the seams of the connection of the parts of the sleeves, a stitch is sewn in.

The solution to this problem is achieved by the fact that:
