Description

Frame for leather goods

The claimed utility model relates to the leather goods industry, can be used to carry leather goods of various assortments on the back, and is intended for school, teenage and youth age groups.

The closest analogue to the claimed technical solution is a backpack published in Bul. “Industrial Designs of Foreign Countries, 1995, Volume 2, Part 1, p. 529, VNIIIPI Moscow; MKPO 3-01, Germany, No. 029439. A backpack is a structure consisting of a front and a back wall, two clinics, a bottom, a valve, two adjustable shoulder straps, statically fastened to the back wall, which has a relief profile. The backpack is designed to carry on the back of school supplies, books, etc.

The disadvantages of the described design include the lack of multifunctionality, the low location of the fastening elements of the shoulder straps can cause inconvenience to wear, the lack of a belt around the waist does not allow the load to be distributed correctly, the design does not satisfy ergonomic requirements.

The technical result of the claimed technical solution is to increase ergonomic and consumer properties. In addition, an extension of the functionality of the claimed technical solution is achieved.

To achieve the specified technical result, a new framework for leather goods was developed, including a rear embossed wall with a bottom, made in accordance with the anthropometric parameters of the dorsal surface of the human body (Figure 1)

The frame for leather goods includes a rear embossed wall with a bottom that is completely molded in accordance with the anthropometric parameters of the dorsal surface of the human body, along the perimeter there is a fixed fastener for the removable part (backpack, satchel, bag, etc.) of the frame in the form of a zipper or Velcro, in addition, in the center of the upper part of the wall is flexible

Zupfer with a fastener for a removable part of the frame; shoulder straps are made of two parts connected by an adjusting element of elastic dense braid; the upper belt, fixed with a rigid clamp, has a fabric overlay duplicated by polyurethane foam, located from the base to the adjusting element; lower belts having a fastener at the end intersect in the center of the lower part of the frame through a movable latch;

, The rear embossed wall with an additional bottom is made integrally formed, moreover, in accordance with the anthropometric parameters of the dorsal surface of the human body. Upon receipt of an uninterrupted and smooth surface of a whole-molded product of complex spatial shape (wall with a bottom) based on information about the sizes of individual parts of the human body, a correlation-regression analysis was used. Objective correlations between various parameters of the human body were established due to anthropometric measurements, moreover, the sample sizes of the number of observations in different age groups were determined on the basis of the need to obtain statistically reliable results.

When solving this problem, the Statgraphics application package was used. Dimensional characteristic data were entered in the editor of the package database into the MAR text file as the following variables: b - age, s - height,

d is the height of the interdigital point, q is the length of the arm, W is the circumference of the neck,

I - chest circumference (2nd inhalation / exhalation), g - waist, t - shoulder width, y - back width,

U is the distance from the base point of the back of the neck to the level of the posterior angle of the armpit,

i is the arc through the highest point of the shoulder joint, o is the length of the back to the waist, taking into account the protrusion of the shoulder blades, p is the height of the shoulder oblique, S is the arc of the upper body,

f is the distance from the waist line to the back of the base of the neck on the side, g is the arc of the upper body through the point of the base of the neck fail

an example of data processing is presented in table 1, which consists of two parts. At the top, estimates of the parameters of a simple linear model and their statistical characteristics are given. The bottom table of Analysis of Variance is the base table of analysis of variation and serves to assess the adequacy of the proposed data model. The figure 2 presents a three-dimensional frequency histogram of the parameters p and f. The figure 3 presents a histogram of the frequencies of parameter c.

In the above example, the sample size was 300 people for boys of the school age group aged 7-12.5 years. The final data processing results are presented in

table 2.

The average typical indicators of the leading signs of typical figures of boys 7-12.5 years old.

table 2

The developed design, the technical result of which is confirmed by the above experimental data, is made of easily formed pedelen used in the manufacture of orthopedic prostheses (EPOS, Germany), the wall with the bottom is molded using standard equipment with a matrix and punch, the shoulder straps are attached in the upper edge scapula with displacement to the spine through tight pads using bilateral holnitene No. 12 OST 17-600-81, the inner part of the frame is made of art ennogo GOST 11107-75 material, the frame has a fastener such as "zipper or Velcro 17-31-78 OCT (depending on the age group, the maximum load aesthetic demands of the consumer) extending along the side

parts and fixed with a non-retractable seam in accordance with OST 17303-79, in the center of the upper part there is a flexible stopper with a fastening element in the form of a magnetic fastener (button) for fixing the removable part, and the removable part can be presented in the form of a satchel, backpack, bag and t .d. depending on the requirements of the consumer and the purpose of this product, which significantly expands the age range of users with this type of leather goods.

The dimensions of the rear integrally formed wall of the frame with the bottom corresponding to the dorsal surface of the human body are presented in figure 4, where 1 is the point of the base of the neck

2 - cervical lordosis

3.4 - thoracic kyphosis (lower edge of the shoulder blades)

5.6 - lumbar lordosis

7, 8 - sacrum (kyphosis)

The wall narrowed to the bottom allows hands to move freely, the location of the upper fastening elements of the shoulder straps with an offset to the spine reduces pressure on the shoulder girdle, eliminates friction during wear, contributes to the greatest fit of the shoulder straps in the neck lordosis; for shoulder straps, a wide dense elastic braid is used, the upper belts have fabric overlays duplicated by polyurethane foam, which also helps to reduce friction of the shoulder girdle during operation; the lower latch of the shoulder straps allows you to adjust the tightness of the frame to the body; the fastening element at the end of the lower belt is designed to tighten the belts around the waist, which in combination with a fully formed bottom gives the best effect of the distribution of load on the spine. The frame is fixed clearly on the figure of a person.
