RU2804042C1RU 2804042 C1RU2804042 C1RU 2804042C1RU-2804042-C1

Abstract

FIELD: fasteners. SUBSTANCE: method is claimed for opening a fastex fastener, consisting of two parts - a fork and a socket, attached to the ends of slings or belts, where the fork is made to have two teeth, a support and thrust strip for fastening the belt, and clamps are placed at the ends of the teeth, which are connected to each other by a curved jumper; the socket is made with a support bar for fastening the belt and having a cavity with guides for inserting the fork teeth into it, where at the end of the guides stops for the fork teeth clamps are placed, and on the sides of the socket openings are formed to the shape of the teeth, with a curved jumper in its middle parts attach a support ring to which one end of the cable is secured, and the cable itself is passed through a through hole in the partition, the ends of which are fixed at the base of the fork teeth, and the cable is pulled along the belt, and the fastex fastener is opened by tensioning the other end of the cable, thus opening fasteners is possible at a distance. EFFECT: opening fasteners is possible at a distance. 4 cl, 4 dwg

Claims (4)

  1. 1. A method for unfastening a fastex fastener, in which a fastex fastener is used, consisting of two parts - a fork and a socket attached to the ends of slings or belts, where the fork is made to have two teeth, a support and thrust strip for fastening the belt, and clamps are placed at the ends of the teeth , which are connected to each other by a curved jumper; the socket is made with a support bar for fastening the belt and having a cavity with guides for inserting the fork teeth into it, where stops for the fork teeth latches are placed at the end of the guides, and openings are formed on the sides of the socket to match the shape of the teeth, characterized in that the curved jumper in a support ring is attached to its middle part, to which one end of the cable is secured, and the cable itself is passed through a through hole in the partition, the ends of which are fixed at the base of the fork teeth, and the cable is pulled along the belt, and the fastex fastener is unfastened by tensioning the other end of the cable.
  2. 2. The method according to claim 1, characterized in that the curved jumper is made smoothly tapering in the middle part.
  3. 3. The method according to claim 1, characterized in that the support ring is made in the form of a hollow cylinder, whose thickness corresponds to the thickness of the curved jumper.
  4. 4. The method according to claim 1, characterized in that a ring is attached to the other end of the cable, through which the cable is tensioned.

Description

The proposed solution relates to semi-automatic fastex fasteners and can be used to connect fabric tapes, slings, and belts. Fastex is a semi-automatic fastener for connecting fabric tapes, slings, belts. The name “fastex” originates from the ITW (Illinois Tool Works) division ITW Fastex. The fastex fastener consists of two parts, attached to the ends of slings or belts. The first (fork) has three prongs, which is where the fastex nickname “trident” comes from. These teeth are inserted into the second, nesting part of the fastex. The tensile load is carried by two side teeth, and the middle one, the guide tooth, serves to stiffen the structure. Subsequently, the rigidity of the structure began to be ensured by partitions between the two outer teeth, and the middle one in a number of fasteners was no longer used. Thus, the fork began to have only two prongs in a number of designs. The two parts are attached to the sling web using fastener loops and simple loops. The locking loop rigidly fixes the canvas in a state of tension. The fastening of the parts occurs automatically when they are connected and snapped into place. Disconnection is made by manually clamping the side teeth. Fastex type fasteners are widely used in tourist equipment, in the design of backpacks and tents. Allows you to easily fasten and unfasten various removable elements. For backpacks this can be a flap, a waist belt, or zip ties. In tents, the inner tent is sometimes attached to the awning using fastex. The designs of fastex type fasteners are described in patents and applications: US4150464A, US4688337A, US5131122A, US5222279A, GB2262962A, US6446314B1, US2012030913A, US2013025097A, US2013031754A, US2015201714A, US9795192B, US8510868, US5546642A. The closest analogue is the decision on application US2012198666A, published: 08/09/2012. The snap fastener includes: a plug and a socket, wherein the plug includes: a base; a pair of legs and engaging parts, the socket including: a body; hole for insertion; body cavity; engaging parts; and a pair of guide surfaces. The guide surfaces, which are formed on the inner surface of the housing space and extend in the insertion direction of the legs, being opposite to each other, each include: a compression part formed continuously with a corresponding one of the engaged parts; and a guide portion formed between the pressing portion and the insertion hole. The spacing between guide portions near the engaged portions is wider than the interval between compression portions near the engaged portions. The angle of inclination of each guide part to the direction of insertion of the plug is less than the angle of inclination of each compressing part to the direction of insertion. The prototype and other known analogues have a drawback in that the fastener is unfastened by pressing the side teeth of the fork protruding through the holes of the socket with your fingers. Thus, in prior art designs, release of the fastener via remote control is not possible. Meanwhile, situations sometimes arise when such disconnection must be carried out remotely, without the use of squeezing the side teeth of the fork with your fingers. For example, in the cold winter, when you are wearing mittens or thick gloves, it is difficult to unfasten the clasp. And if the clasp is located far away and in an inconvenient place, for example, behind the back on the belt of a bag, then how can you press it without removing the bag from your shoulder? There may also be situations when the belt with the fastener is thrown over the support and the fastener is located so high that you cannot reach it with your hand. The purpose of this solution was to solve these problems by adding a remote control fastex to the design of the fastener. The technical result is the ability to unfasten the fastex fastener both in the usual way - with your fingers, and by remote control. The specified technical result is achieved due to the fact that a method is claimed for remote control of unfastening a fastex fastener, in which a fastex fastener is used, consisting of two parts - a fork and a socket attached to the ends of slings or belts, where the fork is made to have two teeth, a support and a thrust bar for fastening the belt, and at the ends of the teeth, clamps are placed, which are connected to each other by a curved jumper; the socket is made with a support bar for fastening the belt and having a cavity with guides for inserting the fork teeth into it, where stops for the fork teeth latches are placed at the end of the guides, and openings are formed on the sides of the socket to match the shape of the teeth, characterized in that the curved jumper in a support ring is attached to its middle part, to which one end of the cable is secured, and the cable itself is passed through a through hole in the partition, the ends of which are fixed at the base of the fork teeth, and the cable is pulled along the belt, and the fastex fastener is unfastened by tensi
