Definitions

• the present patent invention relates to a reinforced door fixed by means of an overlapped series of hooks, supported by the door counterframe and activated with an electric motor, which is controlled with the door lock.
• the door according to the present invention features an entirely innovative construction for two different reasons: first of all, a series of hooks is used to block the door instead of the traditional latches, and secondly the fixing means and all the maneuvering mechanisms are assembled on the door counterframe, instead of being housed in the internal door opening, as it traditionally happens.
• This allows for reinforcing the entire door surface, since it is no longer necessary - as it is in the current models of reinforced doors - to provide spaces to house the traditional latches and their corresponding maneuvering levers, including the lock or the electric motor, if any, in case of automatic latch control.
• the reinforced panels can have the same total thickness as the door.
• the door can also incorporate a small-mesh grate located between two thick plate panels.
• Another advantage offered by the door according to the present invention is represented by the use of a series of fixing hooks assembled on the door counterframe to fit into corresponding slots located on the door wing.
• the divarication of the posts of the door frames is prevented by a series of hooks that, unlike latches, are capable of opposing the force that tends to extract them from their fixing housing, thus making it impossible to push the door counterframe posts away from the door swings.
• FIG. 1 is a view of the door according to the present invention seen from inside, in which some of the surfaces have been partially removed to show the components positioned behind them.
• figure 1 illustrates two different alternative types of reinforced door: the first type with a grate (upper section of Figure 1) and the second type with reinforced glass sheets (lower section of Figure 1);
• Figure 2 is an enlarged view of a details shown in Figure 1 , which shows the coupling between the series of hooks assembled on the door counterframe and the corresponding series of slots located on the door swing;
• FIG. 3 and 4 are a view of the two swings of the door according to the present invention.
• FIG. 5 is a cutaway view of Figure 1 with the V-V plane of Figure 1
• - Figure 6 is a cutaway view of Figure 1 with the VI-VI plane of Figure 1 ;
• FIG. 7 is a cutaway view of one of the frame and of the counterframe, in the assembled position, with the horizontal plane that goes through the axis of one of the fixing bolts used to fix the counterframe to the frame;
• - Figure 8 is a top view of the upper ending section of the frame post and a cutaway view of the lintel of the frame, on which the counterframe has not been assembled yet;
• - Figure 9 shows a cutaway view of the post of the counterframe, which has not been fitted to the frame yet;
• FIG. 10 is an enlarged view of the details marked in Figure 1 ;
• the door according to the present invention comprises a frame (1), composed of a T-section metal profile, designed to be fixed to the wall (M) so that the head wing (1a) of the T-section is placed in a vertical plane which is substantially aligned with the plane of the external door wall (2) with the door closed, as shown in Figure 5.
• the frame (1) is fixed to the wall (M) by means of a regularly spaced series of metal pins (3), to which the frame (1) is welded.
• the frame (1) is coupled with the pins (3) so that the pins are fitted into a corresponding series of U- notches especially located on the wing (1b) of the frame (1).
• the frame (1) is connected to the supporting and blocking pins (3) by means of a series of metal disks (5) which are first fitted into the pins (3) and then welded both to the pins and to the outside of the wing (1 b) of the frame.
• the door according to the present invention also comprises a counterframe (6), composed of an L metal profile, of which one wing (6a) is fixed to the head wing (1a) of the frame (1) by means of a series of bolts (7), which are screwed into corresponding nuts (8), welded to the wing (1a) of the frame (1) and coupled to corresponding bushings (9a) that house dowels (9) which make it easier and faster to center the counterframe (6) to the frame (1 ).
• a regularly spaced series of pairs of bushing (10) is welded inside the wing (6a) of the conterframe, with one bushing housing the fixing bolts (7) and the other bushing housing the centering dowels (9).
• a series of hooks (11) is assembled inside the counterframe (6), with each hook oscillating around a pivot (11a), oriented in orthogonal direction to the head wing (1a) of the frame (1). This means that each hook (11) oscillates on a vertical coplanar plane with respect to the door plane, as illustrated in Figures 5 and 6.
• a sh ' elf (12) is welded inside the counterframe (6), located in parallel position at a certain distance from the wing (6a) of the counterframe (6).
• the shelf (12) is fitted against the series of bolts (8) when the counterframe (6) is fixed to the frame (1), as illustrated in Figure 7.
• a U track is welded inside the counterframe (6), located in parallel position at a certain distance from the wing (6a) of the counterframe (6).
• the bar (15) is provided with a regularly spaced series of threaded holes (15a) used to fix some rack segments (17) to the bar (15) by means of bolts (16), with each rack section engaging with a special toothed sector (11b) located on each hook (11).
• the motor (18) is activated by the door lock, which is schematically illustrated and marked as (19) in Figure 1. It is obvious that on each hook (11) the wing (6b) of the counterframe
• the enclosed drawings illustrate a version of the reinforced door according to the present invention, in which the series of hooks (11) is only present in one of the two posts of the counterframe (6) - that is the post against which the door swing stops - with a series of fixed beaks (20) on the other post of the counterframe - that is the post located nearby the door hinges (21).
• the door according to the present invention comprises a reinforced door (2), which features a series of overlapped slots (23) on both sides (2a), used to engage the hooks (11) and/or the fixed beaks (20).
• Figure 1 and Figure 5 show a reinforced door with a small-mesh grate (23), placed between a welded pair of thick plates (23a).
• Figure 6 shows how the absence of mechanism inside the door (2) allows for having an entirely transparent door made of reinforced glass (22).
• Figures 5 and 6 illustrate various techniques used to hide the wing (1b) of the frame (1) from the external side of the door: - according to one technique, the wing (1b) of the frame is hidden with a marble panel (24);
• the wing (1b) of the frame is hidden with a wooden plate (25);
• the wing (1b) of the frame is hidden with an extruded metal or plastic profile (26);
• the wing (1b) of the frame is hidden with a concrete layer (27).
