Description

A useful model relates to the design of a frame for winding threads, which provides the convenience of threading the thread into the eye of a needle, especially for people with low vision.

There are spools of thread in every home. Coils made of wood in the form of a hollow cylinder with conical protrusions at the ends are widely known. In recent years, threads began to be wound on cardboard reels, also in the form of hollow cylinders, but without end protrusions - a prototype (see. Internet - thread reel).

Everyone also knows the difficulty of threading a needle into the eye. Even people with good eyesight have problems, especially people with low vision suffer from this process. Using a magnifying glass also creates inconvenience, as it needs to be held in some way when one hand is occupied by a needle and the other by a thread.

Needles with an open ear appeared, a thread is threaded into it from above, and not through the eye. But it is also difficult to get into it with a thread with low vision.

The objective of the proposed technical solution is to provide convenience when using the coil, as well as improving the convenience and reliability of winding threads.

The task is implemented as follows. Like the prototype, the proposed coil has a hollow body. In contrast to the prototype, the housing of the proposed coil has the shape of a truncated cone. In the upper part of the cone, a frame is mounted in which a magnifying glass is fixed.

The frame and magnifier can have a round or rectangular shape.

The lens is fixed with an offset relative to the vertical axis of the coil.

The frame can be made removable.

The coil can be made of plastic by injection molding.

The proposed design improves the usability of the product, as simplifies the process of threading a thread wound on a spool into the eye of a needle. The proposed product is shown in the figures:

figure 1 is a side view, section;

figure 2 is a front view, section;

figure 3 - the lens is removable;

4 is a variant of the coil with a removable lens.

The spool for threads contains a hollow body 1, which is made in the form of a truncated cone (figures 1 and 2). The through hole 2 inside the housing 1 provides the ability to use the coil when working on sewing machines. In this case, the hole is worn on the landing pins in sewing machines.

A frame 3 is mounted in the upper part of the truncated cone of the housing 1, in which the lens 4 is fixed. The shape of the lens with the frame can be any - round, oval, flat. The working surface of the lens is offset relative to the vertical axis of the coil to one edge of the frame, which eliminates the protrusion of the lens beyond the frame and protects the lens body from damage.

The coil body is designed for winding threads. The proposed shape of the case is more reliable for winding and preserving the layers of wound threads. The extension of the frame protects them from displacement from the surface of the housing from above, and the extension of the housing itself from below. In addition, the proposed body shape is more stable than that of the prototype, which provides additional convenience for working with the lens.

The lens can be made removable (figure 3). Then the diameter of its legs 5 should slightly exceed the diameter of the upper edge of the housing 1 of the coil. In this case, the lens with the foot 5 is put on the coil body 1 and is thus held in the working position.

A removable lens can be used for coils with a standard cylindrical body 6 (figure 4).

The overall dimensions of the proposed spool with the standard length of the wound thread slightly exceeds the standard dimensions of such products.

The appearance of the product can be supplemented by a variety of textured and color schemes and decorative details.
