Description

KNITTED PRODUCT
Background of the invention
The present invention relates to knitted products, such as socks, tights, panty-hose and the like, having a pocket in the heel region, said pocket being knitted using reciprocating movement of the knitting motion. Description of the prior art
According to the known present prior art, the knitted products of the considered type generally have a pocket made in the heel region. This pocket is adapted to the anatomical shape of the foot and improves in this way the quality of the knitted product, in particular in terms of the wearing comfort. This pocket is traditionally made using a reciprocal movement of the knitting motion, usually on one half of the circumference on which the knitted product is produced. In this phase of the working cycle, knitting of the tarsus region is temporarily interrupted. In the central part of the heel region, the knitting continues without break, whereas in the marginal parts of the heel region the knitting is primarily gradually interrupted, and subsequently gradually taken up again. Hence, primarily a narrowing part, and subsequently an increasing part, arises in the knitted fabric. With this known working method, it happens that the number of stitches of the knitted fabric in the stitch columns of the knitted fabric in the central part of the heel region is substantially higher than in the tarsus region. In the marginal parts of the heel region, the number of stitches in the stitch columns of the knitted fabric is variable. After taking-up again the knitting on the whole circumference on which the knitted product is being made, well-known heel pocket arises. Knitted products of the considered type according to the prior art have basically two pronounced disadvantages. As a result of the variable number of stitches in the respective stitch columns, the stitches of the knitted fabric in the transition region between the tarsus region and the heel region are enlarged and deformed. As a result, these stitches are excessively stressed. In addition to an aesthetic deficiency, this constitution often causes rupture of these marginal stitches, above all in case of men's socks of fine gauge (20 E and higher) and in case of women's tights and panty-hoses. A further disadvantage of the present state of the art is that that, as a result of existing shape of the knitted product, an excess accumulation of the knitted fabric occurs in the tarsus region, which fact negatively affects the wearing comfort. This disadvantage is more pronounced in case of products made of less elastic yarns and yarns of higher count. Summary of the invention The object of the invention is to improve the wearing comfort in case of knitted products, such as socks, tights, panty-hose and the like.
This object can be achieved to a great extent by way of a knitted product according to the proposed invention, where the length of at least a part of the stitch columns in the tarsus region is variable. In order to improve the wearing comfort of knitted products according to the proposed invention, it is of advantage if the length of stitch columns in the tarsus region is maximal on the boundary to the heel pocket and minimal in the central part of the tarsus region.
Compared to the current state of the art, this proposed invention has above all the following two essential advantages. As a consequence to the variable length of stitch columns in the tarsus region, the shape of the knitted product according to the proposed invention is, compared to the current state of the art, much more anatomical, because the knitted product is more curved and much more similar to the anatomical shape of the leg. By virtue of this, much smaller accumulation of the knitted fabric occurs in the tarsus region, and hence the wearing comfort is simultaneously improved, but also a decrease in the stress existing in the stitches of the knitted fabric on the boundary between the heel pocket and the tarsus can be observed. Brief description of the drawings In order to provide a greater clarity, the invention is shown in the attached drawings. In these drawings, Fig. 1 shows a classical shape of a heel pocket in the flattened state with the bordering region of the tarsus, according to the current state of the art. Fig. 2 shows a classical shape of the heel pocket in the flattened state with the bordering region of the tarsus with linearly variable length of the stitch columns in the region of the tarsus. Fig. 3 shows a classical shape of the heel pocket in the flattened state with stepped variations of the lengths of the stitch columns in the region of the tarsus. Fig. 4 shows a classical shape of the heel pocket in the flattened state with variations of the lengths of the stitch columns in the region of the tarsus according to the common curve laws. Fig. 5 schematically shows the shape of a sock made according to the present state of the art, whereas Fig. 6 shows the shape of a sock made according to the proposed invention. Description of the preferred embodiments For a better clarification of the novelty of the proposed invention, a classical heel pocket in the flattened state according to the present state of the art is shown in Fig. 1. The heel pocket P has a central part PJ. and marginal parts P2. In the central part PJ., the length of the stitch columns SP1 of the knitted fabric is constant, whereas in the marginal parts P2, the length of the stitch columns SP2 is variable, because, when knitting in the direction of the arrow 1, it happens that the knitting is, step-by-step, being interrupted and subsequently taken-up again. In this phase of the working cycle, the knitting is interrupted in the region N of the tarsus, so that the length L.konst of all stitch columns SN in the tarsus region N is the same. The heel pocket P is usually knitted on one half of the circumference O of the corresponding knitting motion.
Fig. 2 shows a region of the heel pocket P and the bordering tarsus region N according to the proposed invention. The region of the heel pocket P is the same as in the case of the present state of the art shown on Fig. 1 , whereas in the tarsus region N the length L.var of the stitch columns SN of the knitted fabric is linearly variable, i.e. the difference of the length L.var is made in every stitch column SN according to a line R, and is a constant. At the same time, the stitch column SN1 of the knitted fabric on the border between the heel pocket P and the tarsus region N is longer than the stitch column SN2 on the axis 3 of the tarsus region N. The variability of the length L.var of the stitch columns SN of the knitted fabric between the stitch columns SN1 and SN2 may not only be linear, it can also be designed step- by-step, as shown in Fig. 3. This means that at least two adjacent stitch columns SN have the same length. This variability can also be a general variability, for example according to a common curve K, as it is shown in Fig.4. As a result of variability of the length L.var of the stitch columns SN in the tarsus region N, and as a result of the fact that the stitch column SN1 on the border between the heel pocket P and the tarsus region N is longer than the stitch column SN2 on the axis 3 of the tarsus region N, the knitted product is more curved, and has a better anatomical shape. In case of the solution from the prior art the angle ALFA 1. shown in Fig. 5, between the leg portion and the foot portion is about 120°. In case of the proposed invention shown in Fig. 6, the angle ALFA 2 is substantially smaller, and it is also possible to achieve the value of 90°, corresponding to the anatomical shape of the leg. As a result of this, the accumulation of the knitted fabric in the tarsus region is substantially smaller, or even absent. This brings along substantially greater wearing comfort, above all in case of knitted products made of less elastic yarns, such as for example socks or tights for children. Industrial applicability
This invention concerns the knitting of textile products, such as socks, tights, panty-hose and the like.
