Abstract

Double action hinge.

Double action hinge (1), consisting of a fixed fin (2), a mobile fin (3), a central body (4), two springs (6), two fixed heads (8), two rotating heads (7) tension regulators of both springs (6).

The fixed fin (2) and the mobile fin (3), are they screw the frame and the door respectively, without any type of recess.

The mobile fin (3) has a section in the form of "C" with right angles, which hugs the door immobilizing it as if it were a gag. The fixing screws that placed on the sides of the "C", prevent any type of movement between the hinge and the door, which prevents them from loosen up

Object of the invention

This invention as its title indicates, refers to a new type of reciprocating hinge that allows to open and close totally a door automatically in both directions.

Background of the invention

Currently there are different in the market types of reciprocating or double action hinges for opening and closing doors that are used very frequently and that is It is necessary to keep them permanently closed. This type of hinges have two axially placed helical springs with the two axes of the hinge, and that when the door is operated in a one way or another increase your potential energy and return it when the door is released allowing it to close automatically.

These springs work to torsion, and the necessary driving force is regulated by bolts, from the rest position to a previous voltage that determined based on the size of the door.

Most of these hinges are made of steel laminated and have the double drawback that they loosen due to to continued use and it is also necessary to previously reduce the door and frame to place them.

Another type of double action hinges are those of polyamide, which also have two or more helical springs that work to compression in the direction of its axis. The beginning operating is the same as that of the steel hinge. This Hinge type also has several drawbacks, being the greater their weakness due to the material, since it They break very easily.

Another problem added is that when the door it opens 90 degrees, it stays open, the man's action to close, which implies a loss considerable time, for example when working with mechanical trucks entering and leaving cold rooms also causing considerable thermal losses.

To place these hinges it is also necessary lower the door and the frame, making the final product more expensive.

To solve all these described problems, a new type of metal hinge has been designed, which is described as continuation.

Description of the invention

This swing or double action hinge is mainly composed of a central aluminum body with its respective antifriction shirts and two fins articulated with each other, one of them is fixed to the frame or the wall and the other to the door, screwing them directly without having to do previously No type of recess. The rest are known components of this type of hinges, such as springs, threaded rods and Heads

The fin that is screwed to the door has a C-shaped section, which hugs it, immobilizing it as If it were a gag. The fixing screws that placed on the sides of the "C", prevent any type of movement between the hinge and the door, which prevents them from loosen up

Its operating principle is similar to that of the steel hinges, that is its two springs arranged axially with each axis of rotation of the hinge and that accumulate potential energy when the door is operated in a one way or another. Once the door is released, the spring corresponding returns the energy accumulated by closing the door until it reaches its resting position.

This type of hinges can be built with forged or rolled aluminum or steel, due to which its duration It is unlimited and its placement time is much lower than of any other type of similar hinge.

Preferred Embodiment of the Invention

Between the different methods and materials needed to make this hinge described below, the procedure that the inventor considers most appropriate.

The central body (4), is manufactured from a Extruded aluminum profile cut to fit each hinge, to which the two anti-friction shirts are introduced (5) steel, to avoid wear due to friction of the springs (6) during the opening and closing movement of the door. This central body (4) has a recess (4.1), which allows accommodate the screw heads (11) for fixing the flap fixed (2), and avoid contact with the central body (4).

Both the fixed fin (2) and the mobile fin (3), must be manufactured with flat steel sheets that once trimmed and mechanized, they bend at the angles corresponding to give them the final signature.

The hinge assembly is completed with existing items on the market, such as threaded rods (9), the springs (6), the fixed head (8), the rotating head (7) that retain the anchoring bends (6.1) of the springs (6) to prevent them from turning and also allow them to retire until they acquire sufficient potential energy to return the door (13) to its resting position.

Once nature is sufficiently described of this invention, as well as a practical application thereof, it only remains to add that both its shape and the materials and manufacturing procedure, are subject to modifications, provided that they do not substantially affect the characteristics which are claimed below.
