Description

The utility model relates to light industry and can be used for the production of products used as the working body of button fasteners for special clothing and equipment.

The design of a flat sew-on button is known (US patent No. US1460840A, published on 07/03/1923, IPC: A44B 1/20), which is a disc-shaped figure of small thickness, having two or more through vertical holes in the center for successive threading of a needle with a thread . A coinciding feature is the disc-shaped form of its design. It has low reliability when exposed to sudden physical exertion, as well as a difficult installation method.

The design of a button with an eyelet under the original name "eye-button" is known (US patent No. US1388469A, published 08/23/1921, IPC: A44B 1/24), which is a hemispherical figure, similar to a mushroom cap, with a thin tie at its bases in the form of a loop, in Russian usage called "eye", designed for threading a needle with a thread. A coinciding feature is the loop method, which serves as a shoulder to hold the button with the help of several skeins of thread pressing on it. It has low ergonomics, due to the potential injury risk when pressing on its cap from above due to the orientation of the fixing loop towards the hemmed surface.

A well-known design is a double-slit button (“Canadian”, double-slit button) (link to description: https://www.milla-sidelnikova.com/kak-prishivat-pugovicu-slot.html), which is a disc-shaped figure with two vertical through holes in the center, separated by a partition and intended for threading a narrow sling, which, after stringing a button, is sewn to the surface with two ends.

Coincident features of the prototype and the claimed model are a disk-shaped figure with two vertical through holes in the center and interslit partition.

The design feature and method of attaching the prototype is the most reliable and durable way to create a button fastener, however, it does not allow quick installation of the button to a pre-sewn sling.

The technical result of the utility model is the ability to quickly install a button, for which a narrow ribbon serves as a reinforcing part, on a sling segment pre-sewn on both sides.

To achieve a technical result, a double-slit ribbon button has two external guide slots connected to internal limit slots separating the inner disc, annular groove and the outer rim, so that three main parts of the button are formed: a guide tip, a connecting rod and a bearing part, moreover, the connecting the bar acts as an interslit partition.

In FIG. 1 shows the projections of the sketch planes of the utility model, where: a) top view; b) side view of the longitudinal face of the connecting rod; c) side view of the central-axial section of the longitudinal edge of the rod. In FIG. 2 shows three main parts of the model: 1) guide tip; 2) interslit septum; 3) bearing part. In FIG. 3 shows the internal elements of the model: 4) outer rim; 5) guide slots; 6) annular groove; 7) internal disk; 8) restrictive slots; 9) interslit septum.

The claimed utility model works as follows:

- guide slots (5) (Fig. 4) are used to string a button on a hemmed sling by pulling a tape through them and threading the tape into a pair of restrictive slots (8) of the inner disk (7), separated by an interslit partition (9) in the form of a connecting rod (2);

- the connecting rod (2) (fig. 3) has the main function of holding the button by means of pressure on it from the sling from above, and also serves to connect the guide tip (1) and the bearing part (3), therefore, in comparison with the original design, its width, height and length were increased by a third of the height of the disk to ensure the reliability of the connection of parts;

- the annular groove (4) and the outer rim (6) (Fig. 4) serve for comfortable gripping of the button with the fingers.

The advantage of the claimed object lies in the speed of the main method of installing a button of this configuration to the surface of clothing and equipment without the use of sewing accessories, which will create a reliable and easily installed fastening device.

The development of a three-dimensional model of a button in a software environment (Fig. 4-9) made it possible to manufacture a real prototype using a 3-d printer and test it. A prototype utility model button was made of nylon with a diameter of 30 mm and a width of restrictive tape slots of 12 mm. The sample was successfully tested for basic suitability for stringing on a section of a 15 mm wide and 32 mm long keeper tape attached to a textile surface using guide slots and a tip. On average, the complete installation process can take up to 5 seconds (Fig. 10-13).

Claims (1)

A double-slit ribbon button is a disk-shaped figure having two vertical slots in the center, characterized in that it additionally has two outer guide slots connected to internal limit slots separating the inner disk, the annular groove and the outer rim in such a way that three main parts of the button are formed : a guide tip, a connecting rod and a bearing part, with the connecting rod acting as an interslit partition.
