Description

PRESSURE-TYPE CONNECTION
The present invention refers to a pressure- type connection.
In general, the present invention refers to connections of building elements or parts of machines.
In particular, the present invention refers to pressure-type connections composed of two parts, push-button-like fastening devices, in which the elastic keeping action is obtained by a spring acting on the plane of the fastening device.
In particular, the present invention refers to details made of sheet metals, with at least one recess with a specific shape.
The prior art is given by patent US-B2- 6,773,780, which deals with a self“locking adhesive accessory for the safe disassembling of a connecting component, such as threaded pin on the surface of a substrate. The self-locking accessory comprises a basic device, which carries the connecting component and defines a basic surface adapted to receive a selected hardening adhesive agent, A resilient, pressure-sensitive adhesive element has a first portion carried by the connecting component in a blind side thereof, a second portion fastened to the basic fastening element and a third portion, which extends between the first and the second portions. After the pressed assembling of the basic device with the adhesive agent on the substrate, the connecting component moves for pressing the prima psortion of the pressure-sensitive adhesive element in adherence with the substrate, to allowing pulling the basic device, with a positive force towards the substrate, for the length of polymerization time of the adhesive agent.
Moreover, the prior art is given by patent application US-A1-2011/0016679, dealing with a pressure button comprising a male component, which can be selectively engaged, through a snap action, with a female component comprising an elastic ring, which, under closed button conditions, keeps the male component connected to the female component. The female component comprises a basic structure with a housing seat for the elastic ring. A cover is fastened to the basic structure in order to cover and close, at least partially, the housing seat of the elastic ring.
In many cases, it is necessary or desirable to connect a connecting component or element such as a plaster, a threaded screw or other structure on a supporting substrate. For example, it could be necessary to apply a thin plaster on the skin of a plane or the hull of a boat to repair a hole therein. Alternatively, it can be desirable to assemble a threaded pin or another device on a substrate, for example the windscreen of a car, without requiring a hole in the substrate. In many of these cases, it is necessary that the connecting component is placed on the substrate with a relatively high accuracy, and moreover that a positive force is applied, stressing the connecting component against the substrate at. least for a certain minimum period of time to allow, for example, to harden an adhesive agent such as a hardening epoxy resin or the like, to obtain a substantially optimized and safe bond with the substrate .
On another hand, automatic buttons are used in several ways, for selectively closing or for joining different objects. such as clothes, bags, belts, curtains, boxes and the like, by sewing, riveting, stapling, gluing or other known methods, two corresponding edges of a substrate, which can then be selectively fastened.
Patent US-B2-6, 773, 780 solves the problem of connecting a connecting component or element such as plaster, a threaded screw or other structure on a supporting substrate, while Patent application US-A1-2011/0016679 solves the problem of joining the edges of a substrate of different objects, such as clothes, shoes, bags, belts, curtains, boxes and the like.
An unsolved problem is being able to combine a solution such as that of patent US-B2-6,773,780 with a solution such as that of patent application US-A1-2011/0016679, through gluing or cold welding building elements or parts of machine, with a pressure-type connection composed of two parts, when there is an elastic keeping action obtained by a spring acting on the plane of the fastening device .
Object of the present invention is solving the above prior art problems, by providing a pressure- type connection to allow joining two edges of a substrate of two different objects by using connecting means such as adhesives and threaded or riveted pins .
A further object is providing a pressure-type connection equipped with clinging means to increase the adherence through the different fastening systems as previously mentioned.
