Button affixable by hand pressure

Abstract

A button, provided with the means that allow it to be attached to the article of clothing by manual pressure, avoiding the use of thread, distinguished by being made up of two parts, a main part (1) with a fixed head (2) on top which matches the buttonhole of the article of clothing, followed by a flexible neck (3) which permits the union of the head (2) to the pressure stop (4). This pressure stop (4) allows the fastening of the main part (1) to the article of clothing (5) also, the said main part has a shank (6) which sticks out of the bottom center of the pressure stop (4), and permits the perforation of the cloth, to later connect and set both parts with a backstop (9).

Description

The invention consists basically of a button, provided with the means to fasten it to the article of clothing with manual pressure, avoiding the use of thread, as used with buttons now.

At the present time, to button garments such as shirts, pants, and all kinds of clothing, buttons are generally used. These must be sewn on, using a needle or a sewing machine with thread to keep them fastened on the garment opposite the buttonhole, through which the button goes to fasten both sides of the garment together.

Another way of fastening is to use metal snaps which are riveted with specially designed machines directly on the article of clothing.

Zippers are also used for fastening, which require the use of sewing machines to fasten them to the article of clothing. Velcro is also used as a fastener which like the previous fastener, requires a sewing machine or glue to fasten it to the garment.

Referring to the previous process, we can refer to U.S. Invention Pat. No. 5,115,548 which refers to a button or snap formed by a spherical piece or the buttonhole of a pressure button, made up respectively of a bottom part and a top part riveted together lodging between them a flat flexible material, like a textile or something similar, with the shank of the rivet, made up by one of the pieces, axially fastened by the widened part of the shank beyond the penetrated opening, and for waterproofing between the flat material and bottom and top parts without using additional waterproofing means, proposes that upon inserting the shank of the rivet in the opening, the flat material can be fastened between the shank and one side of the opening, forming a neck.

Another patent in the state of the art is invention patent E96944586 which refers to a fastener with a pressure button that can be locked. The male part is fastened with a locking edge formed on a roller after its joining with the female casing. The roller moves transversally along the direction of insertion of the male part in the female casing and is held in its extended position by a spring in its center. At that moment, the locking edge of the roller acts on the male part. The roller also has an unlocking edge that is in the male part, connected upon the action of the roller and permits it to be unfastened.

To get a pressure button fastener that can be used comfortably, the plan is to use two rollers beside each other in the female casing and put them under the pressure of a spring in opposite direction of the extension. The locking and unlocking edges are created in the slot between the two rollers, partially in each of the rollers. This allows a quick fastening of the two parts of the pressure button without operating the rollers.

Although these systems of joining or fastening articles of clothing meet the proposed objectives, they also have certain drawbacks, such as: The placement on the article of clothing requires other elements, such as machinery in the case of the snaps; needle and thread (as occurs with traditional buttons or Velcro fasteners). This limits the quick placement or repositioning of the part.

The button system of this invention solves the problem in a completely separate and independent way, both in the placement as well as the repositioning, in this last situation it is only necessary to get the replacement there and the change can be performed by any person, without the need of other elements, as happens with the previous systems.

For better understanding of the pressure button system of this invention we will describe it based on the drawings that make up an integral part of the invention, without limiting the invention to the drawings.

FIG. 1 shows a front view of the button fastened to the fabric.

FIG. 2 shows a front view of the button with an expanded view of the fastening stem or shank and a longitudinal section of the lower movable pressure backstop allowing a view of the area of the stem.

FIG. 3 shows a longitudinal view of the movable pressure backstop and a view of the lowest end of the fastening stem or shank.

FIG. 4 shows a front view of the main piece including the head, neck, pressure stop and the shank with grooves.

This invention offers a button with a pressure fastening system that allows quick, manual replacement or installation, avoiding the use of machinery or the like, needle and thread, as with the present systems.

As shown in FIGS. 1 through 4, the system of a button without thread is made up by two pieces, the main part (1) with a fixed head on top (2) which matches the buttonhole of the garment, followed by a flexible neck (3) which permits the joining of the head (2) to the pressure stop (4).

This pressure stop (4) allows the fastening of the main part (1) to the article of clothing (5). In addition, the main part (1) has a rod that sticks out of the lower center of the pressure stop (4) which is shaped like a pin with a succession of fastening grooves (7) which are located opposite the point (8) of the shank (6).

The second part is made up of a movable pressure backstop (9) with grooves on the inside that are located opposite the grooves (7) of the shank (6) in a way that allows its placement and keeps it from coming apart upon connecting together and becomes part of the fastening of the system to the article of clothing.

The shank (6) is pointed on the end to allow the penetration or perforation by manual pressure of the material (5) or the cloth of the article of clothing to later join and set with the pressure backstop (9).

Claims

1. A button, provided with the means to be attached by manual pressure to an article of clothing, avoiding the use of thread DISTINGUISHED by a main part (1) with a fixed head on top (2) which matches the buttonhole of the garment, followed by a flexible neck (3) which permits the union of the head (2) to the pressure stop (4). This pressure stop (4) allows the fastening of the main piece (1) to the article of clothing (5). In addition, the said main piece has a shank that sticks out of the lower center of the pressure stop (4).

2. A button, provided with the means to be attached manually to an article of clothing, avoiding the use of thread as in claim 1, DISTINGUISHED because the main part (1) has a shank (6) which is shaped like a pin with fastening grooves (7) which are located opposite the point (8) of the shank (6). Then finally, there is a part, a movable pressure backstop (9) with grooves on the inside that are located opposite the fastening grooves (7) of the pin shaped piece of the shank (6) to keep it from coming apart after joining together and becomes part of the fastening of the system to the article of clothing.

3. A button, provided with the means to be attached by manual pressure to the article of clothing, avoiding the use of thread as in claims 1 and 2, DISTINGUISHED because the shank (6) is pointed to permit the penetration or perforation of the material (5) or the cloth of the article of clothing to be fastened and set with the pressure backstop (9).
