Abstract

The handle has a tubular part (1) and its ends (2) are bent orthogonally into arcs. Before the ends are bent a solid core (3) of ductile material is introduced into each end. The ends are then bent with the cores inside. The cores are held in the curved parts (4) without the use of additional elements. Blind threaded holes are made in the ends of the cores for fixing the handle to the front of the furniture.

Description

POI (3NEE ~ PERFECTED FOR FURNITURE
IlESERIPTION
PURPOSE OF THE INUENTION
The invention relates to a handle intended for any type of furniture and household appliances, whether doors or drawers, etc., and constituting a pull handle for opening this door, this drawer or the object on which the handle itself is mounted and fixed.

Structurally, the handle is constituted by a tubular body bent in an arcuate manner at its ends, bent ends in which are housed the corresponding cores of ductile material, the free ends of which are provided with blind and tapped holes for fixing to the front part. of furniture.

HISTORY OF INUENTION
Among the many types of furniture handles, there is one constituted by a tubular body with bent ends, the bending being rounded and these bent ends respectively accommodating cores whose free end has an orifice for fixing by screwing to the part. front or cover of the furniture in question.

The process for obtaining the handle described, according to the conventional system, consists of the following operating phases - From a tube of suitable diameter, a portion is cut whose length must be greater than that of the handle that the 'we propose to obtain.

- This portion of cut tube is bent over its two end zones with curved bends along the required radii.

- The angled ends are again cut to the required dimension to determine the depth or the opening even of the handle.

- The solid cores are introduced into the bent ends after having made blind and tapped holes in the external ends of these cores.

- The cores in question are fixed by welding.

- Finally, we remove the burrs, file and polish the ends of the handle.

This process for obtaining the handle has a series of drawbacks and problems, such as the possibility of flattening the tubular portion from which one starts to obtain the handle, precisely when the bending of its end zones is carried out, which will determine a complex operation at the time of having to introduce the nuclei in these bent end zones.

There is also a drawback in having to fix the cores by welding to the bent end zones of the tube which constitutes the handle.

Consequently, the process of obtaining handles according to the system described above will entail that the final cost of the handle will be high.

DESCRIPTION OF THE INUENTION
The recommended handle, while being of the type of handles mentioned in the preceding section, has the great advantage that the tube is bent at its ends in a phase subsequent to that of the introduction of the cores, which it it follows that there is never any deformation in the tube precisely when the bending of its extreme zones is carried out, since the core has already been introduced and that, consequently, there will be no deformations or flattenings and that a perfect tubular configuration will be maintained since, in the extreme bending zones, the tube is massive during the bending phase.

When performing the bending with the core already introduced, no type of posterior weld is necessary to achieve the fixing, since it is materialized by the simultaneous folding of the tube and the core.

Ultimately, a better finishing of the handle is obtained, a reduction in cost and a considerable saving of time.

According to the invention, the steps for obtaining the handle are as follows - we start from a tube which is cut to a length slightly greater than that which we will need; - We have a rod whose section will be appropriate inside the tube from which we leave, rod which will be of a ductile material to be able to bend, cut and screw it, for example aluminum; - Two pieces of said rod are cut and they are introduced into the two ends of the tube from which we started; - the extreme zones where the pieces of rod were introduced are bent with a radius fixed in advance and angles of 900 or others; - the ends are cut to the required dimension; - we carry out the elimination of burrs which may have remained during cutting operations - finally, we carry out the operation of internal screwing at the ends of the cores which constitute the pieces of rod, these remaining caught inside the end zones of the tube .

DESCRIPTION OF THE DRAWINGS
To complete the description which is produced and to contribute to a better understanding of the characteristics of the invention, a description of the present specification is attached, as an integral part thereof, or, by way of illustration and not by way of illustration limiting, the following is shown.

Figure 1 shows a representation in a longitudinal sectional view of the portion of tube from which one starts to obtain the handle of the invention, g including, at its ends, the solid cores or pieces of rod which will be bent simultaneously at the end zones same of the tube where they are housed as shown in the same figure in lines of small lines.

Figure 2 shows a longitudinal sectional view of the handle obtained and produced in accordance with the object of the invention.

PREFERRED EMBODIMENT OF THE INUENTION
As can be seen in the figures in question, the handle of the invention is obtained from a tubular portion C1) of aluminum or a similar material in the end zones (2) of which corresponding pieces of rod are housed massive the two cores (3), so that, once these cores (3) duly introduced in the extreme zones, one proceeds to the production of a bend C5), indicated by hatching in FIG. 1, of these zones ends (2) of the tube Cl) with the cores (3), bends which are rounded, that is to say with the required radii and, moreover, in Soc or other angles, as is clearly shown on the figure 2.

By making the bends in question with the cores (3) inside, these will remain permanently fixed without the need for additional elements, that is to say without the need for welds or other means of immobilization of these cores (3) in the bent sections (2).

Once the configuration of the handle has been obtained, the blind and tapped orifices (S) are produced in the external ends of these cores (3), orifices C5) which will become means for mounting and fixing the handle to the front of the furniture where it is applied, since this handle is intended to be mounted on any type of furniture, whether it is a door or a drawer, etc., or a household appliance to which it is applied and its fastening or fixing will be carried out using screws which will be screwed into its blind holes (53.

Obtaining the handle will be perfectly uniform, since there will be no flattening of the end bend zones since, during the bending, the cores C3) are introduced, preventing any kind of deformation by flattening of the tube C1 ) and also avoid welding to secure it; all this represents better finishing and lower cost compared to conventional handles.

Claims (1)

CLAIM  1 - Improved handle for furniture, of the type formed from a tubular portion (1) with the ends bent orthogonally in an arc, essentially characterized by the fact that the tubular portion (1), from which the handle is obtained proper, receives, in each of its end zones (2) and before the bending (4) is carried out, a solid core (3) of a ductile material, the bending (4) in arc of the end sections (2) of the tube (1) taking place at the same time as that of the cores (3) housed inside these sections, the cores (3) in question remaining retained in the bent sections without the intervention of additional elements; and by the fact that, on the free or external ends of these cores (3), blind and tapped orifices (5) are produced after the bends (4) for mounting and fixing the handle to the part front of the piece of furniture on which it is applied.
