Description

Door handle.

Object of the invention

The present invention, as expressed in the statement of This specification refers to a door handle whose main purpose is to make independent the mechanism of crank turn limitation and recovery it integrates with the shield and the crank, so that it provide more dynamic qualities when conceiving New designs or add additional devices to the handle.

Background of the invention

Door handles are known that have a crank, a shield and a mechanism of limitation and recovery of turn of the crank through which the corresponding axis of square that transmits the turn to the latch. On these handles known said mechanism is integrated in the same piece together with the crank and the shield, which presents drawbacks concerning the limitation of versatility in the designs and in the incorporation of other additional devices.

Description of the invention

To achieve the objectives and avoid the indicated inconveniences In previous sections, the invention consists of a handle for doors that has a crank, a shield and a mechanism limitation and recovery of the crank turn through which it passes the axis that transmits the turn to the corresponding latch.

Novelly, according to the invention, said mechanism is a piece independent of the shield and the crank that is fixed directly to the corresponding door with anchoring means.

In some embodiments of the invention the crank and the shield they can be independent pieces, while in others crank and shield embodiments can be integrated in one piece.

The mechanism of limitation and recovery of the crank turn may include means of retention corresponding to a conviction of axial sliding arranged on the crank.

According to the preferred embodiment of the invention, the aforementioned axis connects the referred mechanism with the crank and is subject to this one by means of captive screws.

With the structure described, the invention presents the corresponding advantages that the limitation mechanism and crank turn recovery constitutes a piece independent, which allows greater versatility of designs and greater ease to incorporate mechanisms additional.

Then, to facilitate a better understanding of this descriptive report and being an integral part of it, it accompany some figures in which with an illustrative nature and not limiting the object of the invention has been represented.

Brief description of the figures

Figure 1.- Represents a profile view and partially exploded of a door handle made according to the present invention

Figure 2.- Partially represents an interior and elevation view. of the handle crank of the previous figure 1.

Figure 3.- Represents an elevation view corresponding to the crank rotation limitation and recovery mechanism the handle of the previous figure 1.

Figure 4.- Represents a perspective view of a handle for conventional doors according to the current state of the art.

Description of an embodiment of the invention

A description of an example of the invention, referring to the numbering adopted in the figures.

Thus, the door handle of this embodiment example is depicted in figures 1 to 3, while figure 4 corresponds to a conventional handle according to the state of the current technique In said figure 4 it can be seen how the shield 1 ', the 2 'crank and the 3 rotation limitation and recovery mechanism of the crank are integrated in one piece, entering the corresponding mechanism 3 inside 4 'square shaft that transmits the turn to the corresponding doorknob and, where appropriate, associate two cranks facing each other. East mechanism 3 incorporates a return spring inside and the corresponding movement limiting stops.

In the handle of the present example, the mechanism 3 becomes a independent piece 5 as seen in figure 1, presenting this mechanism or part 5 the classic recovery spring in its interior and the limits or stops of twist, just as it happened in the mechanism 3.

The new mechanism 5 is fixed directly to the door 7 with anchoring means such as screws 6, as seen in Figure 3

In the present example, the shield 1 and the handle 2 of the handle they are constituted in independent pieces, as can be seen in Figure 1, although in other examples said shield 1 and crank 2 They could be integrated in one piece.

The mechanism 5 of limitation and recovery of the rotation of the crank 2 presents in this example a retaining means 9 consisting of stops that act on a conviction of axial sliding 8 incorporated in the crank 2, as can can be seen in figure 1.

In addition, in this example the square axis 4 connects to the referred mechanism 5 with the crank 2 and has some recesses to hold said crank 2 by means of captive screws 10 that are placed through the aforementioned crank 2, as appreciate in figure 1.
