Description

Title of the invention: Smoke and / or carbon monoxide detector technical field

[0001] The present invention relates to a smoke and / or carbon monoxide detector, the attachment of which to a support is made simple and quick. Previous art

[0002] In the prior art, smoke and / or carbon monoxide detectors are commonly used to ensure the safety of occupants in residential and commercial buildings. These devices are generally mounted on the ceiling or walls to detect the presence of smoke or carbon monoxide and sound an alarm if detected.

[0003] Fixing these detectors to the ceiling or walls generally requires the use of screws and plugs, the number and positioning of which are specific to each manufacturer.

[0004] Thus, when replacing an end-of-life detector with a new model or a model from another brand, the user must make new holes and possibly use new screws to fix the new detector.

[0005] In summary, the prior art has disadvantages in terms of complexity and cost when replacing an existing smoke and / or carbon monoxide detector.

[0006] The prior art does not offer any simple and quick solution for replacing a smoke and / or carbon monoxide detector at the end of its life. Description of the invention

[0007] The objective of the present invention is to provide a smoke and / or carbon monoxide detector which is quick and easy to fix to the wall, in particular as a replacement for an end-of-life detector.

[0008] For this purpose, a smoke and / or carbon monoxide detector has been developed comprising a mounting plate for mounting on a support, such as a ceiling, the plate and the detector comprising complementary and removable means for fixing each other.

[0009] According to the invention, the plate comprises a plurality of through holes, regularly distributed over the surface of the plate, and in particular over the entire internal surface of the plate visible along a central direction orthogonal to the plane of the plate, to allow the detector to be fixed to the support, and in particular by means of screws passing through some holes.

[0010] In particular, the detector according to the invention thus comprises a mounting plate said universal, so that when replacing a detector at the end of its life, it is possible to remove the detector and reuse the screws and the holes already made in the support to fix the detector according to the invention.

[0011] The distribution of the holes over the entire surface of the plate increases the chances of matching some of these holes with the positioning and number of holes made in the support.

[0012] The mounting is quick and easy, saving on screw costs and significantly reducing installation time. It is no longer necessary to drill new holes in the mounting bracket to fix the detector according to the invention when replacing an end-of-life detector. Therefore, the mounting bracket is not further damaged by drilling additional holes.

[0013] According to a particular embodiment, the plate includes a peripheral rim projecting from the plane of the plate, engaged in a complementary groove formed in a base of the detector.

[0014] This allows for a reliable and aesthetically pleasing assembly. The peripheral rim may also include through holes to allow the plate to be fixed to a support and to maximize the chances of matching the fixing holes to existing holes when replacing an end-of-life detector.

[0015] Preferably, the plate is circular, and the additional fixing means are in the form of a % turn locking system.

[0016] In this way, after fixing the plate to the support, fixing the detector to the plate is simple and quick.

[0017] According to a particular embodiment of the % turn locking system, a wall of the protruding rim of the plate includes tabs projecting radially inwards, intended to engage in complementary notches provided in a corresponding wall of the groove in the bottom of the detector.

[0018] The holes made in the plate have a diameter between 3.5mm and 4.5mm, for example 4mm in order to adapt to the type of screws commonly used to fix a smoke and / or carbon monoxide detector.

[0019] In order to further maximize the chances of matching orifices with existing pierces in a support when replacing an end-of-life detector, the orifices are spaced from each other by a distance of between 2.5mm and 3.5mm, for example 3mm. Brief description of the drawings

[0020] Other features and advantages of the present invention will become clear from the following detailed description of a preferred embodiment of the smoke and / or carbon monoxide detector, given below by way of example and not limitation, with reference to the attached figures, in which:

[0021] [Fig-1] is a top perspective view of a smoke and / or carbon monoxide detector according to the invention.

[0022] [Fig.2] is a view similar to that of [Fig.1], viewed from below.

[0023] [Fig.3] is a view similar to that of [Fig.2], without the plate.

[0024] [Fig.4] is a perspective view of the mounting plate, viewed from the inner face of the turntable.

[0025] [Fig.5] is a view of another embodiment of the detector plate according the invention. Detailed description of the invention

[0026] With reference to figures 1 to 4, the invention relates to a smoke and / or carbon monoxide detector (1) comprising a so-called universal mounting plate (2), designed to be mounted on a support, such as a ceiling or a wall, by reusing the screws and the existing holes in the support when replacing an end-of-life detector (1), regardless of the model of detector (1) to be replaced, the number and positioning of the holes.

[0027] For this purpose, the plate (2) includes a plurality of through-holes (3), for example all identical, regularly distributed over the surface of the plate (2) to allow the said detector (1) to be fixed to the support.

[0028] Which holes (3) have a diameter between 3.5 mm and 4.5 mm, for example 4 mm, to fit different sizes of screws and dowels, and are preferably spaced from each other by a distance between 2.5 mm and 3.5 mm, for example 3 mm, to maximize the chances of matching existing drillings with holes (3) for fixing the plate (2).

[0029] In this way, after removing a detector at the end of its life, it is easy to fix the detector (1) according to the invention since the holes (3) of the plate (2) can easily correspond with the holes already made in the support and be used, with the existing screws, to fix the plate (2) to the support.

[0030] The detector (1) is then attached to the plate (2) and the replacement operation is complete. The costs of screws and drilling time are eliminated.

[0031] The detector (1) and the plate (2) shall of course include complementary and removable fixing means (4) which allow the detector (1) to be fixed quickly and easily to the plate (2).

[0032] The plate (2) is preferably circular and the fixing means (4) may be in the form of a % turn locking system, which allows the detector (1) to be engaged and locked in position with a simple rotational movement.

[0033] According to the particular embodiment illustrated in the figures, the plate (2) includes a peripheral rim (5) projecting from the plane of the plate (2), which engages in a complementary groove (6) located in the bottom of the detector (1). This rim (5) reinforces the attachment of the detector (1) to the plate (2) and ensures a precise and secure fit.

[0034] In this configuration, a wall of the rim (5), for example the inner side wall, comprises tabs (4a) projecting radially inwards, which engage in complementary notches (4b) formed in a corresponding wall of the groove (6) in the bottom of the detector (1), to achieve the % turn locking system. Of course, the tabs can be formed in the detector and the notches in the plate without departing from the scope of the invention.

[0035] In order to maximize the chances of matching existing holes in a support when replacing an end-of-life detector (1) with mounting holes (3) for the plate (2), the protruding rim (5) also includes through holes (3) allowing the plate (2) to be fixed to the support.

[0036] According to another embodiment, illustrated in [Fig. 5], the plate (2) also comprises two straight slots (7) aligned with each other, extending on either side of the center of the plate. In the case of a circular plate, these slots (7) are therefore radial and positioned on either side of a central opening. The transverse dimension of the slots (7) is between 3.5 mm and 4.5 mm, for example 4 mm, and the longitudinal dimension is between 25 mm and 35 mm, for example 30 mm.

[0037] The lights (7) are bordered by stiffening ribs (8a). Other ribs (8b) form a grid on the internal surface of the plate (2), and a rib (8c) borders the central orifice.

[0038] In this embodiment, the peripheral rim (5) is hollow and also reinforced by radial ribs (8c).

[0039] In certain embodiments, the plate (2) may have different shapes, such as square, rectangular, or oval, to accommodate different detector and mounting configurations. The additional fastening means (4) may also vary, including clip, slide, or screw systems, depending on specific requirements.

[0040] The plate (2) can be made from various materials, such as plastic, metal, or composites, depending on the requirements for strength, durability, and cost. Corrosion- and flame-resistant materials may be preferred for use in potentially corrosive environments or in the presence of high temperatures.

[0041] In conclusion, the invention makes it possible to provide a smoke and / or carbon monoxide detector carbon with a universal mounting plate designed to facilitate and accelerate the installation and replacement of these safety devices.
