(57) Abstract:

The invention relates to garment production, namely to sewing needles for hand sewing, which can be used by people with partial or complete loss of vision. Sewing needle for hand sewing thread contains a rod with a pointed end, the butt-end and a lug with a transverse groove for threading the filament and the plate spring fixed at one end on the rod tip in the area between eye and tip and covering the slot with the contact surface of the rod and the possibility of bending at an angle to the rod axis. The needle includes an external limiter for the threads formed by the flange groove and the first cut on the rod near its end, and an internal limitation for threads formed side of the transverse groove formed by the second cut, facing the point of the needle. Needle enables a quick threading of the threads in the blind eye by moving the threads on the rod in the direction of the end face to the outer limiter, and then the plate spring back to the point of the needle to the inner limiter associated with the ear. 1 Il.

The invention relates to garment production, namely to sewing needles for hand sewing, which can be opredelennymi difficulties especially for people with weak eyesight.

A sewing needle for hand sewing, in which the rod is made from a material with shape memory effect [Ed. mon. USSR N 962369, CL MCI D 05 B 85/02, 1982].

Before using this well-known needle, it is heated. Thus the eye in the needle takes a round shape that facilitates the process of threading in her thread. Some time after the cooling needle's eye takes the initial longitudinal shape, and the needle is ready for use.

A disadvantage of the known needle is the complexity of the process of threading the yarn and its unsuitability for people with low vision, and especially for people with complete loss of vision.

Known needle, in which the process of threading the yarn into the eye of a needle associated with the use of cut the waste yarn remaining in the eye [Ed. mon. USSR N 1032063, CL MCI D 05 B 87/00, 1983]. This process is difficult to realize blindly.

A sewing needle, containing a rod with a pointed end and an eyelet longitudinal shape, in which the thread devaysa with wire loops [Ed. mon. USSR N 303386, CL MCI D 05 B 87/02, 1971].

The disadvantage of this known solution is the complexity of the process of threading the threads.

The closest to m for threading the filament and the plate spring, one end of the fixed on the rod tip in the area between eye and tip and covering the slot with the contact surface of the rod and the possibility of bending at an angle to the axis of the rod [Patent GB N 1369974, CL MCI D 05 B 85/02, 1973].

In this needle there are no restrictions to the thread, which complicates the process of threading the threads of the blind.

The technical result from the use of the invention is to simplify the process of threading the yarn into the eye of a sewing needle blindly.

This is achieved by the fact that the sewing needle for hand sewing thread, containing a rod with a pointed end and a butt end, a lug with a transverse groove for threading the filament and the plate spring fixed at one end on the rod tip in the area between eye and tip and covering the slot with the contact surface of the rod and the possibility of bending at an angle to the axis of the rod, at the end of the needle along the perimeter of the rod is made groove with a radial cross-section and of a width not less than half the width of the eye.

On the web, in addition, made the first cut, the plane of which is parallel to the lines forming the height of the ear, and the top slice is located on the surface of the rod under the loose end of the leaf spring, the base of the slice to pass through the aforementioned cutoff equal to at least the width of the eyelet, and the groove is made inclined from the ear to the tip of the second and third sections, the plane of which is parallel to the lines forming the height of the eye, while on the side of the groove facing the point of the needle, the cut is made with a radial exit surface of the rod, forming an internal limiter for threads equal to the height of at least half of the width of the eye.

The presence of an external limiter on the rod tip locks the thread as it moves along the rod in the direction from tip to end and prevent slippage of the yarn from peg. The presence of internal restrictor plate under the spring locks the thread just before it is hit in the eye during movement of the thread from the butt to the tip.

Execution of the groove that connects the ear with the surface of the rod inclined sections, facilitates penetration of the thread in the eye and makes this process smoother.

The drawing shows a General view of a sewing needle according to the invention.

Sewing needle for hand sewing thread contains a rod 1 with the pointed end 2 and end 3, the eyelet 4 with a transverse groove 5 for threading the filament and the plate spring 6, one end of the fixed on the rod tip on the area between the lug 4 and the tip 2 and closing the groove 5 with the contact powerlan example fixing springs 6 with the clamp 7, made flush with the surface of the rod 1.

At the end 3 of the needle along the perimeter of the rod 1 has a groove 8 with a radial cross-section and of a width not less than half of the width "a" of the eye 4.

At terminal 1, additionally made the cut 9, the plane of which is parallel to the lines forming the height of the eyelet 4 (the line perpendicular to the plane of the drawing). While the top 10 slice 9 is located on the surface of the rod 1 under the loose end of the leaf spring 6. The base of the slicer 9 runs along the bottom of the groove 8, forming together with the external flange of the groove 8 of the outer limiter for the thread. The length of the cut 9 is equal to at least the width of the eyelet 4.

The groove 5 is made of two inclined from the ear to the tip sections 11, 12, the plane of which is parallel to the lines forming the height of the eyelet 4. Slice 12 can be performed stepwise, with the formation on the surface of the rod 1 thin-walled element 13.

On the side of the groove 5, facing the edge of the 2 needles, cut 11 is made with a radial exit surface of the rod 1, forming an internal limiter for threads equal to the height of at least half of the width of the eyelet 4.

The plate spring 6 is made with an extension in its middle part, at least until 1/6 perimplantitis the spring 6 and its length can be made hollow, and on the surface of the rod 1, the corresponding convexity for a tighter mutual fit.

For convenience needle people with partial vision loss plate spring 6 can be painted in bright colors.

The process of threading the threads in the lug is carried out as follows.

Thread hang on the rod 1 needle-side edge 2. Pin 1 Orient the plate spring 6 located at the top. This orientation is carried out either by the colour of spring (people with partial vision loss) or touch people with complete loss of vision).

For tightly pressed thread to the terminal 1 of the needle ends of the strands can be twisted.

Next move a loop of thread to the end 3 of the needle. After the withdrawal of the thread from the end of the leaf spring 6, the movement of the filament is limited by the external limiter formed by slice 9 and flange grooves 8.

Then move the thread to the edge of the 2 needles. The plate spring 6 when it is deflected at an angle to the axis of the rod 1, providing the opportunity to advance the thread to the inner limiter formed by the slice 11 with radial exit surface of the rod 1.

When progovernment terminal 1.

Then the thread through the groove 5 enters the eyelet 4. The needle is ready for use.

These operations thread do not require intense vision and attention, if you have certain skills are performed quickly and, most importantly, can be performed blindly by people with complete loss of vision.
