Description

[0001] SEWING MACHINE NEEDLE

[0002] The invention relates to light industry, specifically to the manufacture and use of sewing machine needles and sewing needles. It can be used in clothing manufacturing, consumer services, household appliances, and other areas for sewing operations, including embroidery, making toys and other arts and crafts, as well as in medicine, printing, and the manufacture and repair of footwear and other accessories and products. The sewing machine needle is primarily intended for use by people with tremors, visually impaired people, and those with conditions that limit their fine motor skills. It is also primarily intended for use by people who require increased comfort and speed in sewing tasks, as well as faster results (for example, those working in garment manufacturing).

[0003] A sewing machine needle is a commonly used household item. It's a metal rod with a pointed end and an eye for attaching thread near the pointed end. For those with impaired vision, threading the needle through the narrow hole in the eye is a rather difficult task, which can take time and effort.

[0004] A sewing needle is known from the prior art (patent for invention No. 2104351 dated 10.02.1998), which is a rod made of elastic material with a point at one end and at the other with an axial slot expanding from its middle part; it is distinguished by the fact that the needle is made in such a way that its ends on the slot side are spread apart during the release and threading of the thread, and a sleeve with the possibility of axial movement is put on the rod, having a thread on the inner surface corresponding to the thread on the rod, ending in a stop.

[0005] A needle for hand sewing is known (No. 174071 from 09 / 28 / 2017), consisting of a rod with a pointed end on one side and an eye on the other side, characterized in that the eye is made of two holes in the form of ellipses, located one after the other along the longitudinal axis of the rod in mutually perpendicular planes, while the surfaces of the holes are made with a rounding having a radius equal to or less than 1 / 2 the radius of the rod.

[0006] A hand sewing needle (patent no. 2312942, dated December 20, 2007) is a hand sewing needle designed primarily for the visually impaired. The hand sewing needle consists of a shaft with an arcuate bend, one end of which is pointed, and the other end has an eye with mutually spring-loaded side cheeks and a slit ending in a wedge-shaped expansion at the end of the needle. The slit in the eye is located in the plane of the arcuate bend of the shaft. The shaft's curvature is characterized by the following parameters: the distance from the chord to the furthest point of the arcuate bend ranges from 1 mm to 6 mm. This invention allows visually impaired people to more confidently and successfully perform the procedure of threading the eye of a hand sewing needle.

[0007] The closest analogue to the claimed invention is a hand-held sewing needle (patent no. 2312942 dated August 27, 2006, based on application no. 2006113625 dated April 24, 2006). The similarity between this needle and the developed sewing machine needle is that both are designed to allow for quick and easy threading.

[0008] The disadvantages of the well-known sewing needle include the fact that the eye of the needle is not kept closed, so the spring-loaded side cheeks often damage the thread fibers, which in some cases leads to twisting of the thread fibers, entanglement of the thread itself or the thread fibers, or to breakage of the working thread.

[0009] The thread can unexpectedly fall out of the spring-loaded cheeks, leaving the needle empty. Furthermore, the open eye of the needle makes it fragile. If the needle is damaged or breaks, a fragment or "piece" of the needle can suddenly fly off or injure the user, forcing them to temporarily stop sewing. The problem addressed by the development of the present invention is the creation of a sewing machine needle free from these shortcomings. The design of the developed sewing machine needle ensures its adaptation to people with disabilities, the visually impaired, and those with fine motor impairments, as it speeds up and simplifies the procedure of threading the eye of the sewing machine needle, thereby increasing ease of use.Adapting people using the developed sewing machine needle will increase their demand in society for work in the sewing industry, consumer services, household, and other areas where sewing operations are performed, as well as increase their motivation.

[0010] The technical result of the claimed invention is a reduction in the time spent on sewing and the achievement of results in less time. This is achieved primarily through the easy insertion of the thread into the eye (which eliminates the need to repeat this procedure and ensures the thread is inserted the first time) and the additional strength of the design (which significantly reduces the need to replace a broken sewing machine needle with a new one).

[0011] Compared to conventional needles, the time required to thread the working thread through the eye is reduced. Another problem with sewing needles and sewing machine needles with open eyes is that when working with thin or delicate fabrics, passing the sewing machine needle or sewing needle through such fabric can be difficult due to fabric or fabric fibers getting caught in the eye through the open side of the eye. This can lead to a stoppage of more than 20 seconds, and if the situation repeats, the work will stop again. Also, when threading an open eye, the thread can break or be damaged, requiring the thread to be threaded again, wasting time. This situation will not occur with a sewing machine needle with a closed eye.

[0012] The advantage of this design is that the eye remains closed, preventing the thread fibers from twisting or tangling. The working thread does not break, but moves freely. It does not fall out, become damaged, twist, or tangle. This ensures the sewing machine needle can pass through the fabric and return to its original position without hindrance, even when sewing thin or delicate fabrics.

[0013] Another advantage of this model is that, compared to sewing machine needles and sewing needles with open eyes, it offers additional strength while still allowing easy threading. It's well known that the weakest point of a sewing machine needle is the area near the eye.

[0014] I'll give an example below to demonstrate the added strength of a sewing machine needle with a closed eye. Consider two sewing machine needles made of the same material and quality, one with a closed eye and the other with an open eye. If the tip of the sewing machine needle is supported by both sides of the eye, and therefore supported by both sides of the eye, since both sides are closed, the sewing machine needle will be significantly stronger (at least 35% stronger, and possibly 50% stronger) than a sewing machine needle with an open eye, where the tip is supported by only one side of the eye, since the other side of the eye is open and therefore does not support the tip of the sewing machine needle.

[0015] A sewing machine needle's durability is essential for reducing sewing time, as it reduces the amount of time spent on sewing-related manipulations. It also contributes to safety and ease of use. A broken sewing machine needle is dangerous and, perhaps, one of the most frustrating sewing experiences a user sometimes encounters. It can negatively impact motivation, causing the user to pause sewing for a while, and, in some cases, completely eliminate the desire to continue. Therefore, the less frequent such breakages are, the better and more convenient it is for the user, allowing them to achieve results faster.That is, if a sewing machine needle breaks and needs to be replaced with a new, whole sewing machine needle (requiring a series of actions that require attention, effort, and time), and if the need for such an action is less frequent (for example, half as often as before, in the case of sewing machine needles with an open eye, or 35% less often than before), then such a saving of time and attention will certainly contribute to a faster result, a reduction in the time spent on sewing-related work and ease of use of the sewing machine needle, and, in addition, will have a beneficial effect on the user's motivation.

[0016] A sewing machine needle is primarily intended for people with tremors and visual impairments, as well as for those with conditions that limit their fine motor skills who love and want to sew. Many of us remember how, as children, our grandmother would call us grandchildren to her and ask us to help her thread the eye of the machine. She had good enough vision that sewing was easy, but the process of threading the eye was difficult and time-consuming, requiring repeated attempts.

[0017] The developed design helps solve this problem. The sewing machine needle is intended primarily for people who need to perform sewing work with increased ease of use and increased speed and with accelerated results without the need for additional repetitions of manipulations associated with threading the eye of the sewing machine needle (sometimes, for example, if the thread is capricious or frays, delaminates (in which case you often have to take scissors and cut off the end of the thread, wasting time, and after the thread becomes capricious again, cut off part of the thread again) or if the user has tremors or poor eyesight, repetitions of threading, sometimes additionally cutting off the end of the thread, can be more than 7 in a row (each, for example, 4 seconds) and in this case, only one of the seven ends with threading the eye, which means 6 extra repetitions, in such cases saving time,When using the developed sewing machine needle, the time it takes to thread the thread is 24 seconds per threading, which can be repeated several times (for example, more than 7 times over 2 hours of work). This is especially necessary when frequently changing thread colors. Thanks to the ability to thread the thread through the eye the first time, achieving a faster, pleasing result without the additional time and effort required to repeat the procedure, the time savings are (7 minus 1, or one successful threading equals 6). Then, multiplying 6 by 24 seconds equals a time savings of 168 seconds over 2 hours of work. This is especially necessary when frequently changing thread colors, for example, when embroidering or sewing multicolored items and changing the thread color every 5-10 minutes. In such cases, the time spent on threading the eye is reduced even more.

[0018] The essence of the invention is that a sewing machine needle is a rod with a tapered end and an eye close to the tapered end of the rod, wherein the side of the eye is made with a sleeve placed on it with a gap in relation to the said side of the eye and the possibility of its radial rotation to enable the winding of the thread when threading the thread into the eye.

[0019] The edges of the sleeve can be rounded to achieve a more streamlined needle shape. A sewing machine needle is also offered with an eye side that has a smaller diameter than the other side. This prevents the sleeve from creating additional bulk, and allows for a more streamlined needle shape, allowing for easier and more seamless penetration of the fabric and removal of the needle during sewing. This also allows for a large enough eye to allow for easier and more free thread insertion.

[0020] A sewing machine needle, characterized in that the side of the eye on which the bushing is located is made in the form of a "crossbar" extending between the other two sides of the eye with the ability to provide the sewing machine needle with a more streamlined shape for the possibility of easier and more effortless penetration of the sewing machine needle into the fabric and for the possibility of easier and more effortless exit of the sewing machine needle from the fabric.

[0021] The essence of the invention is explained by drawings.

[0022] Fig. 1 shows a sewing machine needle, front view, where 2 is the bushing, located with a gap on the eye side. The sewing machine needle is made in the form of a rod 5 with a tapered end 6.

[0023] Fig. 2 shows a part of a sewing machine needle, a front view, where 1 is the eye, 2 is the bushing, located with a gap 3, on the side 4 of the eye 1. The sewing machine needle is made in the form of a rod 5 with a tapered end 6 and has a working thread 7, threaded through the eye 1. Moreover, the gap between the side of the eye and the bushing may look barely noticeable, since the side of the eye is under the bushing, and also because the side of the eye can be made with a smaller diameter than the other side of the eye, free from the bushing, in order to provide the needle with a more streamlined shape. Fig. 2 shows a section A-A, where side 4 of the eye 1, 3 is the gap, 2 is the bushing, located with a gap 3, on the side 4 of the eye 1.

[0024] Fig. 3 shows a section of a sewing machine needle, where side 4 of eye 1, with sleeve 2 placed on it, is made with a smaller diameter relative to the other side of the eye. There is a gap 3 between the side of the eye made with the smaller diameter and the sleeve to allow for radial rotation of the sleeve.

[0025] Fig. 4 shows a section of a sewing machine needle, in a variant where the side of the eye is made in the form of a "crossbar" 8 between the other two sides of the eye, free from the bushings. Moreover, the side of the eye made in the form of a crossbar is 8; the other two sides of the eye are 4; the eye is 1; the bushing is 2; the gap between the bushing and the side of the eye made in the form of a "crossbar" is 3. With the ability of the bushing to wind the thread on the bushing 2 during its radial movement due to the fact that the bushing is located with a gap 3 on the eye side of the "crossbar".

[0026] It is also possible to have a sewing machine needle with two bushings on both sides of the eye, where each said side of the eye is made with a bushing placed on it with a gap in relation to the said side of the eye and with the possibility of its radial rotation to enable the winding of the thread when threading the eye.

[0027] It is also possible that the edges of the bushings can be made rounded.

[0028] The following design features are also possible: a sewing machine needle characterized in that the side of the eye on which the bushing is located is made offset towards the center of the eye, with the ability to provide a sewing machine needle with a more streamlined shape, a sewing machine needle characterized in that the sides of the eye on which the bushings are located are made offset towards the center of the eye, with the ability to provide a sewing machine needle with a more streamlined shape, a sewing machine needle characterized in that the eye is made in the form of a slit-gap between two bushings, with the ability to tighten the thread between the two bushings, with radial rotation of the bushings, due to radial rotation of the bushings, wherein, for example, with radial rotation of one bushing clockwise, the second bushing will rotate counterclockwise.

[0029] When threading working thread 7 into the eye, in one embodiment, we bring thread 7 to eye 1 of the sewing machine needle and, using a free finger of the same hand or a finger of the other hand, slightly rotate bushing 2 so that the thread is wound onto bushing 2 and, with its radial rotation (rotation is possible due to the bushing being located with a gap 3 on side 4 of eye 1), guides the tip of the working thread into the eye of the sewing machine needle so that its radial rotation helps the tip of working thread 7 pass completely through eye 1 of the needle. When threading the eye of a sewing machine needle with a "crossbar" 8, the procedure can be the same. When threading a sewing machine needle with other embodiments, the procedure can be the same. When threading a sewing machine needle with two hubs and a slit-shaped eye, the thread can be brought to the eye in the usual way as described above or folded in half, and the rotation of the two hubs will draw it into the eye.

[0030] Thus, when performing the simplest and shortest manipulations, the end of the thread will be inside the eye and the result achieved is a reduction in the time spent on work related to sewing, namely, on the action of threading the thread into the eye of the needle for a sewing machine and in achieving the result of work with less time expenditure.

[0031] When embroidering, it is necessary to change the thread colors, and to change the thread color, it is necessary to frequently remove the old thread from the eye and thread a new thread of a different color in its place. The use of the developed design will ensure the user's convenience during embroidery and speed up the work process.

[0032] The design of the sewing needle will allow for a wider range of user ages and can be used by both younger and older users, thereby expanding the range of sewing needles.
