Abstract

The single part (1) of the door, is hollowed by fine milling and with side moldings of solid wood flush with the covering panels (4) and (5), the ends of parts (3.1) of the premolding (3) being arranged at an angle of 45°.

Description

OBJECT OF THE INVENTION

The invention herein defended consists of a manufacturing procedure of agglomerated particle doors and thus manufactured doors, of the type which are carried out by means of pantographs and are presented with counterboring and covering moldings.
This invention is characterised by a specific manner of manufacturing the door, mill hollowed and with side moldings, and with 45° angled parts with solid wood pieces arranged flush with the panel covering

BACKGROUND OF THE INVENTION

The doors produced by pantograph are provided with rounded corner hollowed parts, because the continuous machining passing operation prevents the formation of angles at said corners.
Thus, the molding squares are finished off rounded, so that this construction is easily identified.
On the other hand, when an angled square corner finish is desired, the manufacturing procedure is that of the consecutive assembly of preformed parts, in such a manner, that the construction is started by the lower crossbeam, subsequently placing and attaching the side columns, arranging the internal part or parts, the new intermediate crossbeams, the agglomerated boards or the glass panes, the veneered sheets, the enamelled glass etc. and finally, the upper crossbeam which closes the assembly.
This procedure, though correct, is highly expensive in relation to time and manpower, apart from requiring greater specialisation of the finishes.
The applicant is unaware of the existence of door manufacturing procedures which, parting from agglomerated boards, mill the hollows and leave angles on view with solid side moldings, coplanar with the covering panels.

PROCEDURE OF THE INVENTION

The invention which is the object of the present Specification refers to a manufacturing procedure for agglomerated particle doors, of the type which are carried out by means of pantographs, milling the internal perimeters of the hollows, and which are presented with recess finish and with covering moldings, as well as with a conventional solid wood framing, joined by means of male-female spigots to the boards.
This invention is characterised by a specific door construction procedure, also made from one single piece, though with angled finish of the corner squares, based on a milled hollowed door arrangement and with a premolding applied at the sides of said cutting.
This milling produces a very slightly rounded finish, side projecting at both ends near the vertex in the manner of very small circular area.
The premolding, also of solid wood, is applied by lateral bonding, the individual premolding parts being joined at an angle of 45° and covered by the covering panel or panels, generally boards derived from wood and of the various conventional covering panels, including shielding plates, the latter either on one side of the door or on both sides.

DESCRIPTION OF THE DRAWINGS

In order to complement the description which is being carried out, and with the object of facilitating a better and easier understanding of the characteristics of the invention, the present Specification is enclosed, forming integral part of the same, with a set of drawings in which, with illustrative and non limitative character, the following has been represented:
Figure 1 shows a front elevational view of the door with agglomerated particle boards.
Figure 2 shows a partial cross section of said door, in order to observe the finish of the same.
Figure 3 is a constructive variation for the inclusion of a transparent sheeting, for example of glass.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the above description, the present invention refers to a manufacturing procedure for agglomerated particle doors and doors thus constructed, of the type produced by a pantograph, with perimetral milling of hollows, with recessed finish covered by molding, as well as with a male-female spigot solid wood framing (2), essentially characterised by the construction of the door from one single piece (1), with angled finishing of the corner edges, based on hollowing (1.1) by milling, part (1) in a very slightly rounded vertex finish, in two small orthogonal circular areas (1.2)
The premolding (3), made of solid wood, is side bonded, intermediate to two high pressure stratification panels (4), of the type denominated PROTEC, and a double panelling of solid wood (5), covering the premolding (3) with the panels (5), so as to attach the assembly, the small circular area recess (1.2) remaining covered by the edges of the PROTEC panels (4), as well as the angled joining (3.2) at 45° of the individual premolding (3) parts (3.1)
Finally, the final molding is obtained by a mortising with fine drill, jointly with the external corners (3.3) of the premold (3) with the overlapped ends of panels (4) and (5), thus placing the most external edge (3.4) of the mold mortise coplanar with the edges (4.1) and (5.1) of the joint mortise of the respective door panels (4), and (5), showing the final appearance of the angled hollowing out, due to the fact that the ends of the circular area recess (1.2) are imperceptible.
Alternatively, the premold (3) may be provided with another larger internal, mortise (3.5), in order to attach the conventional, transparent sheets (6) on the same.
This description is not made more extensive with the understanding that any expert in the Art shall have sufficient information to understand the scope of the invention and its derived advantages, as well as to be capable of reproducing the same.
It is understood, that if the essentials of the invention is not altered, both the variations in the materials and the shape, size and arrangement of the elements are capable of variation characterised within the same.
The terms used during the description and the meaning of the same shall always be considered in a non limitative manner.
