Description

This invention relates to a button device and a method for attaching it.

Modern buttons and their counterparts have various ways of attaching to clothing, such as:

1) a button with two or four sewing holes. Buttons with three holes are a rare variety;

2) button with an eye - on the back of the button there is a protrusion with a single hole, for which the button is sewn to the clothes;

3) the so-called "Denim button" - is not sewn to clothes, but is attached with a thorn (a button on a thin so-called "Rigid leg") and (so-called "Floating" leg) rivets, although varieties with a hollow rivet in the upper recess of a button on a rigid leg.

Traditional methods of attaching a button have the following disadvantages:

1) the cost of sewing on a button;

2) the complexity of attaching buttons requires skills in working with sewing tools;

3) the need for significant material and time costs.

There are various ways to address these disadvantages. One of the devices for attaching the button and the method of attaching it is protected by application 2011105282/12, 26.08.2009, publication No. 2501504. The device and method for attaching a button allows one of a variety of conventional buttons to be attached, such as buttons having two or four holes. This device uses a lead-through and a take-up part instead of a needle and thread. The lead-through has a U-shape with parallel legs, each of which has a pointed end and a locking element located close to it, forming toothed portions. The receiving part is also U-shaped and has an engaging receiving means. The button is attached by interacting and fixing the two pieces inside the holes of the sewn-on button. The pre-pass piece is threaded through the fabric. For ease of use, the passage piece and the receiving piece are fixedly attached to the gripping element, which is used for gripping with the fingers. After fastening the button, the gripping elements are separated along the tear line.

However, burrs may appear on the rupture lines, which can cause discomfort during the operation of the product. Due to the fact that the fixing of the pass-through and the receiving part occurs inside the button holes, there is little space for the interaction of the two parts. Consequently, the restraining means must be small enough to require minimum manufacturing tolerances. Also, this invention does not provide for the possibility of its reuse, which leads to additional material costs.

In the application 2013120412/12, 04/30/2013, a method for attaching a button is proposed. In this method of attaching a button to a traditional thread, details and additional attachment means are added in the form of a tubular rivet, into which, in the workshop, you need to thread a thread with a button previously strung on it and fix the thread in a tubular rivet using a knot, glue or a riveted wedge. Then, already in the sewing workshop, the rod of the tubular rivet is threaded into the fabric and inserted into a washer with a fastening hole.

This method does not solve the problem of labor intensity, does not reduce economic costs, but adds additional costs for the means of attaching a button. Also, when using this method at home, you will need additional devices and skills. Additional fasteners on the fabric of the product will give excessive thickness, which also will not contribute to the comfort of its use.

The purpose of the present invention is:

- elimination of the process of sewing on a button with the economic benefit of its use;

- ease of attachment and the possibility of reuse, thereby increasing its attractiveness for production and consumption;

- the possibility of repeated use of the device, which can significantly reduce the material costs of the consumer and improve the ecology of the environment;

- simplicity of design, which will save labor costs and automate the attachment processes.

The present invention provides an attachment device and method for attaching buttons quickly, easily and securely, and for detaching a button quickly and easily.

The simplicity of the design of the invention contributes to economy in manufacture as well as in its use.

The device is easy to use without additional skills. An additional advantage lies in the fact that the proposed device and method for attaching a button makes it possible to automate the process.

A distinctive feature of this device is that:

- the penetrating part (A1) has two functions; instead of a thread, it secures the button body with a fabric or other material (30) and at the same time serves as a leg for the button body (A2);

- the receiving part (A2) can act as a button body and carry the functional and decorative part of the button and also be part of the button body on which the decorative and functional part of the button is attached (20). (see Fig. 2);

- the engaging receiving hole (11) is provided with receiving elements, by means of which the locking elements (3) with the sharpened ends of the legs (1) pass into the engaging receiving hole (11) of the receiving part (A2). Moreover, the receiving elements can be made in the form of gaps (16) or chamfers (14) (gentle edges).

Chamfers (14) are located on the sides (17) of the engaging receiving hole (11) (see Fig. 1 bottom view). The clearances (16) complement the receiving opening (11). At the places where the gaps (16) complement the opening (11), at least one holding means (15) is located (see Fig. 3).

FIG. 1Z to 18Z show a proposed method for attaching a button device according to the invention. In this example, the receiving piece (A2) has an engaging receiving opening (11) with gaps (16) serving as receiving means. FIG. 1Z and 2Z, the penetration piece (A1) penetrates with its pointed ends (2) through the fabric or materials (30). The pointed ends are sharp enough to pierce the fabric and pull the fibers apart, but not sharp enough to damage the fabric fibers by cutting through them. The penetrating part (A1) passes through fabrics or materials to its base (4) and is fixed in it by means of its bends (5), creating a slight tension on them. Then, as shown in FIG. 3Z and 4Z, on the pointed ends (2) of the penetrating part (A1) with fixing elements (3), the receiving part (A2) is put on through the engaging receiving hole (11) supplemented with the receiving element, in the form of a gap (16). Further, as shown in FIG. 5Z and 6Z, after the passage of the fixing elements (3) through the gap (16), the receiving part (A2) turns, while one neck (6) of the passage part (A1), sliding along the wall of the fixing hole (11), slips into one of the sides (17) and is fixed there, and the second neck (6), sliding along the bend of the gap (16), is compressed and reaches the retaining means (15), as shown in FIG. 7Z, and, having slipped on it, is springy unclamped into the second opposite side (17) of the fixing hole (11), as shown in FIG. 8Z. FIG. 9Z the button device is shown secured and assembled.

Reliability and tightness of fixation is provided by several aspects at once:

1) the penetrating part (A1), falling into the fixing hole (11), is compressed and, due to its spring properties, tending to unclench, creates a stress that forces it to be within the fixing hole (11);

2) lateral movement of the penetrating part (A1) is prevented by the retaining means (15);

3) locking elements (3) prevent sliding back out of the receiving part (A2);

4) to go further through the fixing hole (11) is prevented by the shape of the bracket of the penetrating part (A1) expanding towards the base.

In order to be able to disassemble the device and disconnect it from materials or fabrics, it is necessary to disconnect the receiving part (A2) from the penetrating part (A1) (see Fig. 10Z-12Z). One of the legs (1) of the penetrating part (A1) must be pressed with sufficient force so that the neck (6) can jump over the retaining means (15), then the receiving part (A2) is turned in the appropriate direction so that the neck (6) the penetrating part (A1) could spring and be released into the receiving element in the form of a gap (16), as shown in FIG. 13Z. Then, as shown in FIG. 14Z and 15Z, the receiving part is rotated in the same direction so that the second neck (6) of the penetrating part (A1) can be released from the side (17). FIG. 16Z - 18Z, it is shown how the receiving part (A2) is removed through the engaging receiving hole (11) supplemented with the receiving element (16), then the penetrating part (A1) is removed from the fabric or materials (30). After the penetrating part (A1) is removed from the fabric or materials.

The fibers that make up fabrics and materials are capable of fully or partially restoring the integrity of a previously punctured area.

It should be noted that during assembly and attachment of the device, as well as disassembly of the button device, both part (A2) and part (A1) can be rotated separately and simultaneously in the opposite direction. This will depend on usability in both manual and automated ways. The direction of rotation is also determined by the design of the fixing hole (11) and the gap (16) and the location of the holding means (15).

FIG. 1B - 10B show the attachment method and the unfastened buttons according to the invention, where the engaging receiving hole (11) is supplemented with receiving elements in the form of chamfers (14) (shallow edges) and it is also shown as an example that the body of the receiving part (A2) can be part buttons and carry other decorative or functional devices (20). FIG. 1B and 2B, the penetration piece (A1) penetrates with its pointed ends (2) through the fabric or materials (30). The pointed ends are sharp enough to pierce the fabric and pull the fibers apart, but not sharp enough to damage the fabric fibers by cutting through them. The penetrating part (A1) passes through fabrics or materials to its base (4) and is fixed in it by means of its bends (5), creating a slight tension on them. Then, as shown in FIG. 3B and 4B, a receiving piece (A2) is put on the pointed ends (2) of the penetrating piece (A1) through the receiving members (14). The sharp ends (2) of the penetrating part (A1) are placed in the shallow edges of the chamfers (14) leading to the sides (17) of the fixing hole (11), then on the receiving part (A2) or on the penetrating part (A1), or just two depending on the convenience of use, both manually and automatically, sufficient force is applied to push the sharp edges (2) together with the fixing elements (3) through the sides (17) of the fixing hole (11). The pointed ends (2), sliding with their outer edges along the shallow edges (14) of the receiving elements, compress the penetrating part (A1) and slide into the fixing hole (11). Further, Fig. 5B shows how the pointed ends (2) with the fixing elements (3) of the penetrating part (A1) located just below the fixing elements (3) pass through the fixing hole (11), and the penetrating part (A1) is expanded and rests against the necks (6) against side (17) of the fixing hole (11).

Reliability and tightness of fixation is provided by several aspects at once:

1) the penetrating part (A1), falling into the fixing hole (11), is compressed and, due to its spring properties, tending to unclench, creates a stress that forces it to be within the fixing hole (11);

2) lateral movement of the penetrating part (A1) is prevented by the narrow transverse dimension of the fixing hole (11);

3) locking elements (3) prevent sliding back out of the receiving part (A2);

4) to go further through the fixing hole (11) is prevented by the shape of the bracket of the penetrating part (A1) expanding towards the base; if necessary, the presence of shoulders (21) is provided below the neck (6) of the penetrating part (A1).

FIG. 6B-10B show a method for releasing a button device from fabric or materials. To do this, it is necessary to disconnect the receiving piece (A2) from the penetrating piece (A1). The legs (1) of the penetrating part (A1) must be pressed with sufficient force so that they compress and the fixing elements (3) together with the pointed ends (2) can come out of the fixing hole (11) (see Fig. 6B-8B). Then, in FIG. 9B, the penetrating piece (A1) is removed from the receiving piece (A2), and in FIG. 10B is removed from the fabric (30). It should be noted that the legs (1) of the penetrating part (A1) can be released alternately by applying sufficient compressive force to one of the legs so that the locking element (3) together with the pointed end (2) can come out of the locking hole (11), then the leg (1) is removed from the fixing hole (11) while the penetrating element (A1) is tilted in the opposite direction. Then the second leg (1) with fixing elements (3) and pointed ends (2) is removed.

Standardization of the types of dimensions of the bushing (A1) and the receiving part (A2) will reduce the economic costs of production and the cost of using this device.

The scope of the invention is not limited by the description presented, and other variants of its implementation are possible within the scope of the attached claims.

The receiving part (A2) can be of any shape, depending on the material of execution and the designer's idea. The engaging receiving hole (11) and the receiving elements (14) and (16) can also have various shapes and their combinations depending on the material of execution and the designer's idea. Obviously, changes can be made in the shape of the penetrating element (A1) and it can change depending on the materials of execution and also on the basis of design thought, and of course, guided by the practicality of use. The fixing elements can be made in the form of cuts in the legs (1), and the fixing elements can also protrude from the legs of the bracket. The base of the penetrating part (A1) can also change its shape.
