Description
The object of present invention refers, as the title indicates, to an improved metal
door which consists of a leaf made up by two panels or plates connected to each other,
one inside the other, with a space between them, like a chamber, which is to be filled with
an adequate insulating material and of a metal frame like that used for security doors
provided with a set of hinges attached to the door leaf side edge which allows fastening
door leaf to frame and making it possible pivoting said door leaf between two end
positions.
Different types of metal doors are widely known, having leaves made up by two
panels asembled one into the other, and provided at sides and top with a thin stop flange
or rib what provides a poor appearance of whole assembly.
Furthermore, since the assembly of top and side edges between the two door leaf
panels is done by sliding, the bottom edge must show a configuration completely different
to that of side and top edges, as otherwise it would not be possible the sliding assembly
of both panels or plates. Usually bottom edge of one of said panels remains completely
exposed, so that oxidation may initiate through said edge and progressively advance
towards the other panel or plate, since metal doors are not normally made of steel, as this
would be to costly, but materials basically used for this type of door are iron plates
adequately treated, like for instance galvanized plates.
Therefore, in this type of known metal doors made by two panels assembled to
each other, the panels bottom edges are cut out so one of the said panels or plates remain
exposed loosing the protection against oxidizing.
On the other hand, the different used known door frames have in their cross section
and along the longitudinal shape facing the leaf edge a recess to which the leaf is fastened
by means of a hinge assembly consisting of two parts connected respectively to leaf edge
and to door frame. However, most of these frames present poor conditions with respect
to external actions and specially with respect to forces exerted on connection elements
between door leaf and frame.
The improved metal door object of present invention has been developed with the
purpose of correcting those defects which appear in the existing doors.
The object of present invention refers to an improved metal door, comprising:
- connection and assembly means between both panels, made up by several bents
which define a shape in side and upper and lower edges of both panels, consisting of:
- a first U shape defined upon a first or exterior panel extending perpendicular to main plane of said first panel on both side and upper edges; said first panel lower edge is provided with an oblong groove located perpendicular to said panel main plane.
- a second shape defined upon a second or interior panel consisting of a double L shape extending perpendicular to said second panel main plane on both sides and upper edges; said L shape covers said U shape of first panel on its side and upper edges, providing a perfect assembly of better quality than those existing in the market; said second or interior panel defines, in its lower side, an L shape which extends perpendicular to main plane of said second panel used for attaching said oblong groove located in said first panel; and
- housing means for a lock provided with one or more locking points, preferably a security lock provided with a longitudinal L shape channel arranged on one side of first or exterior panel; said channel houses the lock and also improves panel stiffnes, what results in an improved security.
- a metal flame, with a longitudinal shape facing door leaf presenting a double 90° step shape, allowing the door leaf to turn around said longitudinal shape to open the door and to define with first of said 90° steps a turning end position which corresponds to door closing position;
- one or several security hinges made with a preferably metallic material, consisting of two elements, one pivoting around the other, to be attached respectively to door leaf and door flame, allowing the leaf to turn around said frame longitudinal shape, the element attached to frame consisting of an end strip arranged perpendicular to said element main plane, with a 90° bent in its free end, and of size basically similar to that of 90° step of frame to be attached, with the element attached to leaf consisting of an end strip perpendicular to said second element main plane, with length basically similar to that of width of leaf to be attached; and
- connection and fastening means of each one of the said security hinge elements to, respectively, said door leaf and said frame, consisting preferably of a series of screws with corresponding holes drilled on said hinge end strips as well as on attached elements.
From the previous description it can be clearly seen the advantages of improved
metal door object of present invention, like an improved structural resistance of metal
door leaf, provision of a wing profile to insure a perfect fastening of a sealing joint
housed in an U shape formed by said assembly; conforming a longitudinal U shape
channel allows the housing of a lock with several locking points, thus providing a higher
stiffness to corresponding panel and a higher security level; furthermore, giving the
possibility of keeping door leaf fastened to frame in a fixed and secure position and of
allowing turning door leaf around corresponding frame longitudinal shape between two
end positions, with hinges connecting door leaf to frame provided with security elements
which can avoid possible damages on area of contact between door leaf and frame as a
result of external actions.
To better understand the object of present invention, a preferential practical
embodiment of the improved metal door is described as follows, with reference to
attached figures 1 to 4. Said figures represent:
Figure 1 shows a perspective view of the improved metal door object of present
invention.
Figure 2 shows a section through line AB of metal door leaf shown in figure 1.
Figure 3 shows a section through line CD of metal door shown in figure 1.

hinge set consisting of two elements pivoting one around the other.
Such as it is represente in figure 1, the leaf (1) of metal door consists of two panels
or plates, an exterior panel or plate (2) and an interior panel or plate (3), assembled to
each other, one inside the other, Said panels (2, 3), either both or only one may be
provided with recesses (4) to hold decor profiles on door leaf A space is left between
both panels (2, 3), like a chamber, which is to be filled with an adequate insulating
material (12) (see figures 2 and 3) like poliurethane, mineral wool, etc.
Figures 2 and 3 show the sections of door leaf represented in figure 1, as per lines
AB and CD respectively, wherein the characteristic features of metal door object of
present invention can be seen.
Furthermore, said figures represent connection and assembly means between both
panels (2, 3), consisting of several bends which define a profile on side, upper and lower
edges of both panels.
Said connection and assembly means comprise:
- a first U shape (5) defined on exterior panel (2) extending perpendicular to main plane of said exterior panel (2) on both sides and upper part, also the said exterior panel (2) lower part is provided, such as it is shown in figure 3, with an oblong channel (6) arranged perpendicular to main plane of said exterior panel (2);
- a second profile defined on interior panel (3) consisting of a double L shape (7) which extends perpendicular to main plane of said interior panel (3) on both sides and upper parte, also said interior panel (3) provided, in its lower edge, with an L shape (9) which extends perpendicular to main plane of said interior panel (3), intended to hold said oblong channel (6) arranged on exterior panel (2).
Said double L shape (7) mounted on interior panel (3) covers the U shape (5) of
exterior panel (2), on side and upper edges, thus providing a perfect assembly of better
quality than those existing in the market.
Furthermore, leaf (1) of improved metal door is provided with an U shape (10)
longitudinal channel mounted on one side edge of exterior panel (2), prepared to house
a lock with one or several locking points, like, for example, a security lock. Said channel
(10) houses the lock and provides improvedstiffness to corresponding panel, improving
its security level.
In the case that lock built in improved metal door leaf (1) comprises several locking
elements, said U shape longitudinal channel (10) consists of a profile (11) which connects
the different locking elements.
It needs to be enphasized that the connection of lower side of both panels (2, 3)
defined by oblong channel (6) facing down, arranged on exterior panel (2), with a
complementary wing or L shape (9) attached to and lapping over exterior wing provided
on interior panel, allows for provision of a brush o brush or seal (not shown in the
figures) arranged to stop air flow through space between said door leaf (1) lower side
and floor surface.
In accordance with figure 4, improved metal door frame (13) is fastened, by means
of a series of hinges, to door leaf (1), through one of door leaf side edges and allowing
said leaf (1) to turn around said frame profile between two end positions. The frame (13)
which is made of metal or similar material, is provided with a longitudinal shape for
connection to door leaf (1) showing a double 90° step (14) shape, consists of two 90°
bent adjacent portions.
This double step allows door leaf (1) to turn around the frame (13) profile so as to
complete door opening and to define, by means of first step (14a) an end turning position
which corresponds with door closing position.
Security hinges are made of a metal material and consist of two elements one
pivoting around the other. The means for fastening hinges to door frame consists of an
end strip (17) arranged perpendicular to main plane of said element, with its free end (18)
bent 90° and of size basically similar to that of one of 90° steps of corresponding frame.
The other fastening element corresponds to door leaf (1) and consists of an end strip (19)
perpendicular to main plane of fastening element, and with a length basically similar to
the width of said door leaf.
Fastening and assembly means for each security hinge element consist of a series
of screws (20) with matching holes (21) drilled on both the hinge end strips and on
elements to fasten to.
Once the nature of present invention has been thorougly described, including an
embodiment of same, it is only to be added that it will be possible to introduce changes
