Description

MODULAR DOOR ASSEMBLY FORMING A CHIME
AUTONOMOUS.

 The invention relates to a modular door assembly comprising an independent peephole and a chime; it relates more particularly to a landing door equipped in accordance with the invention.

 Most generally, landing doors or the like comprise an outer face and an inner face enclosing the door proper and a through orifice, intended to receive the optical peephole. In practice, the installation of the chime requires the intervention of a specialist who pierces the amount of the door frame to accommodate the doorbell button connected by electrical connections to the chime in turn connected to the power supply. This operation is costly.

 Recently, it has been proposed to replace the electrical connections with infrared emitters dedicating the remote chime. However, this solution remains expensive and always requires the installation of the various elements within the framework of the door.

 The invention overcomes these drawbacks. It aims for an autonomous modular assembly forming an optical chime and peephole, easy to install, even by non-professionals and requiring no drilling in the frame.

This modular door assembly forming an autonomous chime, for a door comprising an external face and an internal face, and a through hole from one face to the other intended to receive the optical peephole, is characterized:
- in that the door has a second through orifice parallel to the first orifice;
- in that the outer face has a plate making it possible to position the optical peephole in the first through hole and the doorbell button in the second hole;
- in that the inner face has a box crossed and maintained by the peephole, and which comprises an electronic assembly connected by connections to the doorbell button and to a loudspeaker, as well as to a battery of electrical supply of the electronic assembly.

Advantageously, in practice:
- the peephole is made in two parts screwed into each other, the ends of which have washers in the form of a crown which, by bearing on the outer plate and on the inner case, keep these two elements firmly applied against the door;
- the doorbell button is a sensitive button formed in two concentric and coaxial parts, each connected by a connection to the electronic assembly, actuation being done by flush with the finger, without significant pressure and without mechanical system;
- the electronic assembly essentially comprises:
a DC power source,
a detection unit connected to the touch sensitive
doorbell and chime to trigger the latter when the
finger is flush with the button,
a set of amplification and adjustment by potentiometer,
intended to amplify the electrical signal emitted,
finally, a loudspeaker;
- the loudspeaker is of the waterproof plastic membrane type, in order to correctly reproduce the sound;
- The external face of the box has, at the height of the loudspeaker, a hole or a plurality of holes for diffusing the sound emitted by the latter;
- the electronic assembly also has a potentiometer for adjusting the sound volume, accessible and adjustable from the outside;
the electronic assembly also includes a means of protection against accidental reversal of the polarity of the battery;
- the power supply stack, housed inside the case, includes an access hatch;
- the front plate also has a location to form or receive the name plate.

 The manner in which the invention can be implemented and the advantages which ensue therefrom will emerge more clearly from the embodiment which follows, supported by the appended figures.

 FIG. 1 is a schematic representation in summary perspective of a modular assembly according to the invention shown in section in FIG. 2.

 Figure 3 is a block diagram of the electronic assembly.

 The door designated by the reference (1) has an outer face (2) and an inner face (3). In a known manner, this door is pierced with a through orifice (4), intended to receive the optical peephole designated by the general reference (5), formed in two parts, respectively an external part (6) with its washer (7) , and an inner part (8) with its end washer (9). The internal ends opposite the washers (7) and (9) are threaded (10) to maintain and tighten.

 According to a first characteristic of the invention, the door has a second through orifice (20) parallel to the first orifice (4).

 According to another characteristic of the invention, the outer face (2) of the door (1) has a plate (30) making it possible to position the front part (6) of the optical peephole (5) by pressing the washer (7) , and the sensitive button (31) formed in two concentric coaxial parts, respectively a central part (32) and a crown-shaped part (31) disposed in the second through orifice (20).

 According to another characteristic of the invention, the inner face (3) of the door includes a box (40) crossed by the internal part (8) of the peephole, so that the washer (9) comes to rest on it , so that once the optical peephole (5) in place, the two washers respectively outer (7) and inner (9) bear firmly on the outer plate (11) and on the housing (40).

 According to another characteristic of the invention, the housing (40) receives an electronic assembly designated by the general reference (50), connected by connections (51,52) to the two parts (31,32) of the doorbell sensitive button and a diaphragm speaker (55). In a variant, the portion of the housing disposed opposite the diaphragm of the loudspeaker (55) is pierced with a plurality of holes so as to ensure good diffusion of the sound emitted.

 The electronic assembly essentially comprises (see FIG. 3) a detection assembly (70), connected by the connections (51,52) to the two parts (31,32) of the doorbell sensitive button, in turn connected to the chime ( 71) intended to generate the melody. An amplifier (72) adjustable by a potentiometer (73) accessible to the user, amplifies the sound emitted and transmits it to the loudspeaker (74) with plastic membrane to better withstand vibrations and to be more insensitive to humidity. When the user is touching the sensitive button (31,32), the detection part (70) activates and transmits the electrical signal to the chime (71) which amplifies it in (72) to transform it into an audible sound ( 74).

 The housing also includes a battery of electrical power (60) which can be put in place or removed by means of a hatch (61) provided for this purpose. In a practical embodiment, the power supply battery (60) is of the 9 volt (500 mA / H) type BP3 type, with a typical consumption of 100 mA / H and a consumption at rest of 10 Na.

 The electronic assembly (50) also has a protection element against reverse polarity and a pause time between two trips of two seconds.

 The front plate (11) also has a name plate (12).

 The modular assembly according to the invention is easy to install, since it suffices to pierce in the door a second through orifice (20) parallel to the first (4) pre-existing, then to install the front plate ( 11), to position the front part (6) of the peephole and the doorbell (31,32), then to set up the case (40) on the rear face, to secure the assembly by screwing the rear part (8 ) of the optical peephole in the front part (6), the assembly then being perfectly positioned and operational.

 This device is easy to build and set up, even by non-specialists. it is compact and autonomous, and does not require drilling in the door frame.

 It can therefore be successfully used for all doors, even existing ones, in particular on landing doors.
