Description

RISK DETECTOR HOUSING, RISK DETECTOR AND WORKPIECE

SUPPORT FOR SUCH A BOX

TECHNICAL FIELD OF THE INVENTION

The present invention is directed to a presence or risk detector housing, a presence or risk detector and a support piece for such a housing. It applies, in particular, to fire risk detectors, presence detectors, carbon monoxide for example, and gas leakage.

STATE OF THE ART

The autonomous smoke alarm detectors, and more generally the presence or risk warning detectors positioned on a wall, have the role of emitting a signal when a presence or a risk is detected to warn a user.

In most current systems, the transmitted signal is a sound and / or visual signal, and sometimes wireless. When the detector is not equipped with a remote control, the user must press a button positioned on the detector housing to deactivate the emission of the alarm signal or to carry out a test of the detector's functioning. In some systems these two functions can be activated by two separate buttons.

These systems are usually placed high up to be in the open air and, in the case of fire detection because the hot air rises, they are preferably fixed to the ceiling or wall of a room or room. 'a local. Thus, in current systems, it is difficult for a user to activate one of the detector's features without the aid of a chair or stepladder. This last aspect is at the origin of three risks for the user:

In the first place, the user may be injured by falling off the ladder or stepladder, or, in their absence, by using a piece of furniture, or an assembly of furniture, not having the function to be escalated, to reach the detector. Secondly, the button being of small size and sometimes placed on the side of the detector, the user can not, or hardly, actuate it with the help of a pole, such as a brush handle for example, without risk tearing it off.

Thirdly, because of the annoyance caused by a trigger and the difficulty of neutralizing the alarm, the user is encouraged to permanently disable the detector by removing the batteries to prevent the emission of the signal.

OBJECT OF THE INVENTION

The present invention aims to remedy all or part of these disadvantages, for this purpose, according to a first aspect, the present invention is a risk detector housing and / or presence to be fixed on a support piece attached to a wall , which includes :

at least one deformable connection connecting the housing to the support part,

a sensor with a value of a physical quantity nearby,

a risk and / or presence detector configured to detect a risk and / or a presence as a function of the value sensed,

- a transmitter that emits a signal when a risk and / or presence is detected and

- At least one switch, positioned so that a movement of the housing relative to the support part changes the state of the switch to disable signal remission.

Thanks to these provisions, a user can disable the transmission of the signal by pressing on several parts of the housing. This advantage allows a user to use a boom when the device is unreachable by hand, thus avoiding risk-taking related to climbing. On the other hand, the ease of deactivation of the signal does not encourage the user to make the detector inoperative by removing the batteries for example.

In embodiments, the support piece has a relief and the switch is positioned facing the relief, a support on the housing causing the deformation of the connection and the support of the relief on the switch until the closure said switch, the closing of the switch causing the interruption of the transmission of the signal. The advantage of these embodiments is that they facilitate the replacement of the electrical components of the device contained in the mobile part of the device. This allows in particular to make the device modular to facilitate maintenance. In addition, it makes it possible to fix to the fixed part any kind of electronic device provided that this device has a switch positioned facing and activated by the relief.

These embodiments allow the casing to tilt in two directions.

In embodiments, the housing comprises a plurality of deformable links and a plurality of switches, the connection between the housing and the support member has a play in at least one direction perpendicular to the movement of the housing.

These embodiments allow the user to close one or more switches depending on the location where he exerts the support, and thus to control one or more functions by a switch or a combination thereof.

In embodiments, the housing object of the present invention comprises a deformable support rod, on a switch, positioned facing the support piece so that the support member causes the displacement of the rod that supports on the switch during a movement of the housing.

These embodiments allow on the one hand, greater variability in the positioning of the relief relative to the switch in the housing, the switch being reached by the rod, and secondly to be able to activate the switch itself when the race of the housing in the support part is not sufficient.

In embodiments, the deformable connection exerts a restoring force on the housing, the switch being closed in a state of rest as long as the deformable connection is not deformed.

These embodiments make it possible to verify that the detector is mounted on the support piece. In addition, the activation of a function of the detector is done by pulling on the housing. In embodiments, the support member comprises at least one relief and the housing comprises at least one switch, the housing being free to rotate along an axis perpendicular to the plane formed by the support piece to put at least one switch with at least one relief.

The advantage of these embodiments is to choose the function or functions accessible from supports on the housing.

In embodiments, the housing has a bent relief.

It is noted that the figures are not to scale.

FIG. 1, which is not to scale, shows a sectional view of an embodiment of the detector 50 which is the subject of the present invention. This risk and / or presence detector 50 comprises:

a support part 20 comprising:

a means 210 for attachment to a wall 30,

a stop 225, against which the housing 10 is positioned in a state called "rest",

- a relief 205 and

a deformable link 215 connecting the casing 10 to the support piece,

a housing 10,

a deformable link 215 holding the housing 10 in a so-called "rest" state, away from the relief 205,

a means 10 for holding the housing 10 at one end, remote from the support part 20, from the travel carried out by the housing 10,

a sensor 1 15 of a value of a physical quantity near the housing 10,

a detector 120 of a risk and / or presence configured to detect a risk and / or a presence as a function of the value sensed,

a transmitter 125 which emits an alert signal when a risk and / or a presence is detected and

a switch 130, positioned so that a movement of the housing 10 relative to the support member 20 changes the state of the switch 130 to disable the emission of the signal.

The support piece 20 is, for example, a ceiling base having a hollow housing and a bayonet type fixing system for securing the housing 10 to the support part 20. When the housing 10 is fixed in the support part 20, this housing 10 is movable in translation along the hollow housing, this housing forming a guide in translation for the housing 10. The abutment of the bayonet makes it possible to maintain the housing 10 in the housing of the support piece 20.

The support piece 20 further comprises a relief 205 positioned in the housing, this relief 205 being a long shape such as a rod, for example, oriented towards the opening of the support piece 20. This relief 205 is positioned in view of an opening of the housing 10 when the housing 10 is inserted into the housing.

The support piece 20 is fixed to a wall 30, such as a ceiling for example, by the fixing means 210. This fixing means 210 is, for example, one or more screws passing through one or more openings of the support piece 20. .

In variants, the fixing means 210 is a nail passing through an opening of the support part 20 and a portion of the wall 30.

The support piece 20 is connected to a deformable connection 215, such as a spring or a resilient flexible blade for example, in order to maintain the housing 10 against the stop 225. The deformable connection 215 is maintained by a fastening system, not shown. In the case of a flexible strip, this strip is for example directly molded in the support part 20. The elastic effect is obtained depending on the shape of said strip and the mechanical properties of the material used for molding. This strip is put in tension when the housing 10 is positioned in the support part 20. In the case of a spring, this spring is for example maintained by a clip in the support part 20. In variants, the deformable connection 215 is fixed to the housing 10 or directly molded in the latter.

In variants, the deformable connection 215 exerts a restoring force on the housing 10, the switch 130 being closed in a state of rest as the deformable connection 215 is not deformed.

In variants, the support piece 20 comprises at least one relief 205 and the housing comprises at least one switch 130, the housing 10 being free to rotate along an axis perpendicular to the plane formed by the support piece 20 to face the at least one switch 130 with at least one relief 205.

In variants, the housing 10 has a bent relief.

The support piece 20 comprises the relief 205 and the switch 130 is positioned facing the relief 205, a bearing on the housing 10 causing the deformation of the link 215 and the support of the relief 205 on the switch 130 to the closure said switch 130, the closing of the switch 130 causing the interruption of the transmission of the signal.

In variants, the housing 10 comprises several deformable links 215 and several switches 130, the connection between the housing 10 and the support part 20 has a play in at least one direction perpendicular to the movement of the housing 10.

In variants, the deformable connection 215 is elastic.

The housing 10 is, for example, a closed plastic receptacle having at least one opening positioned facing the relief 205 and the orifices facing the sensor 1 15. The housing 10 comprises at least one stop 135 positioned on the outside of the housing. housing 10 blocking the passage of the housing 10 through the opening of the support member 20 when the stop 135 of the housing 10 comes into contact with the stop 225 of the support member 20. This stop may for example correspond to a male connector of the bayonet used to fix the housing 10 to the support piece 20.

The deformable link 215 is, for example, a spring configured to push the housing 10 toward the opening of the support member 20 until the housing 10 is retained by the stopper 225 obstructing this opening. When the detector is hooked to the ceiling, the deformable link 215 holding the detector at one end of its stroke is, for example, gravity.

In other variants, the casing 10 is attached to the deformable link 215, this deformable link 215 being fixed to the support piece 20. These variants make it possible to constrain the travel of the casing 10 and have the advantage of requiring no stop 135 or stop 225.

The housing 10 comprises the sensor 1 15 of a value of a physical quantity.

This sensor 1 15 is, for example, an optical smoke sensor in the case where the detector 50 is a fire risk detector 50. In variants, this sensor 1 is a gas sensor. In other variants, this sensor 1 is an infrared sensor, ultraviolet or a CCD ("Charge-Coupled Device") sensor for detecting flames. In other variants, this sensor 1 is an ultrasonic sensor, an infrared sensor or an image sensor for detecting a physical presence. In other variants, the housing 10 comprises a sensor whose sensed value is used to determine a presence and a sensor whose sensed value is used to determine a risk.

The detector 120 is, for example, an electronic printed circuit configured to detect a risk when the value of the sensed physical quantity is greater than a predetermined limit value. For example, when the density of smoke in the air captured by the sensor 1 is greater than a predetermined value by the skilled person skilled in the field of the risk detected by the detector 120. In variants, the detector 120 comprises a plurality of predetermined limit values and means for selecting, by a user, a detection threshold from said predetermined limit values. The selection means is, for example, a touch screen or a push button associated with a seven-segment display.

In other variants, the detector 120 is configured to detect a presence as a function of a value sensed by the sensor 1 15.

The emitter 125 of a signal is, for example, an electroacoustic transducer or a piezoelectric component configured to emit an audible signal when a risk and / or presence is detected. In variants, the transmitter 125 is a light source configured to flash when a risk and / or presence is detected. In other variants, the transmitter 125 is an antenna configured to send a wireless signal, for example, to a central alarm, a remote server or a portable terminal communicating when a risk and / or presence is detected. The communication between the transmitter 125 and the recipient device is achieved, for example, by the implementation of IEEE 802.1 1 called "Wi-Fi".

The switch 130 is, for example, a switch in the open position as long as no support is made on the switch 130. When the switch 130 is in the open position and a risk and / or presence is detected , the transmitter 125 emits a signal until the switch 130 is put in the closed position, a predetermined time is reached without the switch 130 is put in the closed position or until the detector 120 does not detect any risk or presence for a predetermined time limit. In order to close the switch 130, a user must press on the housing 10 so as to push the housing 10 into the housing of the support part 20 by deforming the deformable link 215. movement, the relief 205 is inserted into the opening of the housing 10, presses and closes the switch 130, which has the effect of controlling:

at the transmitter 125, the stopping of the current signal transmission, and / or

a change in the limit value beyond which the detector 120 determines that the value sensed by the sensor 1 is representative of a risk or a presence and / or

a deactivation of the detector 120.

After a predetermined time, the transmitter 125 and / or the detector 120 can be reactivated.

In variants, when no emission is made by the transmitter 125 but a support is made on the housing 10, the transmitter 125 temporarily emits a signal. These variants make it possible to test the proper functioning of all or part of the detection and warning chain: the power supply, the activity of the sensor 1 15, the processing of the information of the detector 120 and the capacity of the detector. issue of the issuer 125.

In variants, the support piece 20 comprises at least one of:

the sensor 1 15,

the detector 120,

the transmitter 125 which emits a signal when a risk and / or a presence is detected and

the switch 130.

In the variants where the support part 20 includes the switch 130, the housing 10 comprises a relief, not shown, to press the switch when a support is made on the housing 10.

In variants, the detector 50 comprises neither the sensor 1 15 nor the detector 120 but comprises a means of reception, not shown, of a signal comprising a data representative of the detection of a risk and / or a presence emitted, for example, by a central alarm.

In other variants, the pressing of the switch emits a sound of mechanical origin, such as a "click", for example, or of electronic origin, by means of a piezoelectric component or a loudspeaker. speaker for example. The advantage of these variants is to warn the user of taking into account the action performed on the switch.

In other variants, the deformable connection 215 exerts a restoring force on the housing 10. The "rest position" of the housing 10 is, for example, in contact with the bottom of the base, the relief 205 closing continuously the switch 130. The advantage of these variants is to verify that the housing 10 is mounted on its support member 20. In these variants, a user must pull the housing 10 to open the switch 130 to control a function of the detector 50.

FIG. 2 shows a particular embodiment of the housing 40 which is the subject of the present invention. This case 40 of risk and / or presence detector to be fixed on a support part 20 fixed to a wall 30, comprises:

a deformable link 440 connecting the casing 40 to the support piece,

a sensor 415 of a value of a physical quantity near the housing 40,

a detector 420 of a risk and / or presence configured to detect a risk and / or a presence as a function of the value sensed,

a transmitter 425 which emits an alert signal when a risk and / or a presence is detected,

a plurality of switches 430, positioned so that a movement of the housing 40 with respect to the support part 20 changes the state of at least one switch 430, the processing performed as a function of the switch or switches having changed state being different,

a deformable support rod 435, on a switch 430, positioned opposite the support piece 20 so that the support piece 20 moves the rod 435 which presses a switch 430 during a movement of the housing 40.

The housing 40 is, for example, a hollow housing having a plurality of openings, each opening being positioned facing a switch 430. In variants, the housing 40 is similar to the housing 10 described with reference to Figure 1.

The sensor 415 is similar to the sensor 1 described with reference to FIG. The detector 420 is similar to the detector 120 described with reference to FIG. The transmitter 425 is similar to the transmitter 125 described with reference to FIG. The deformable connection 440 is, for example, a spring or a cable. The link allows the casing 40 to tilt around a tilting point 445.

In variants, the deformable connection 440 is a ball joint. This ball joint allows the rotation of the casing 40 around a point, preferably positioned on an axis perpendicular to the general plane formed by the support piece 20 and passing through the center of the support piece 20.

In variants, the deformable connection 440 is a shaft positioned on the tilting point 445 and allowing the housing 10 to tilt in directions coplanar with the support part 20, each direction causing a support on one or more different switches. In these variants, each switch, during a change of state, controls the realization of a different function.

Each switch 430 controls a different function of the detector 50. For example, a first switch 430 actuates, when the switch changes state, issuing a temporary sound signal to test the operating capacity of the sensor-detector assembly -transmitter. A second switch 430 interrupts, for example, the emission of a signal by the transmitter 425. A third switch 430 triggers the emission of a pairing signal with another set of housing 40 and support pieces 20, with a communicating portable terminal or with any type of recipient of the transmitter 425. The simultaneous support of several switches makes it possible to control other functions, for example. Each switch 430 is positioned facing a relief to interrupt the emission of the signal when the switch 430 associated with the relief is closed, a support on the housing 40 causing the deformation of the link 440 and the support of the relief on the switch 430.

The link 440 for tilting the housing 40, the support by a user on different parts of the housing causes a tilting of the housing 40 in different directions. Depending on the part of the casing 40 swinging towards the support piece 20, a relief of the support piece 30 among a plurality of reliefs is inserted in one of the openings of the casing 40, a switch 430 among the switches 430 changing state in contact with said relief. In variants, a plurality of switches 430 change state simultaneously when the housing 40 switches in one direction. In variants, the housing 40 comprises at least two switches 430, the deformable connection allowing a rotation of the housing 40 about an axis generally perpendicular to the plane formed by the support part 20, the support part comprising at least one relief 205 During an initial rotation, at least one switch 430 is placed opposite a relief, each other switch 430 being placed, or not, opposite another relief depending on the rotation performed. Once the rotation is completed, the angular positioning of the link 440 is locked, each pressing on the housing causing the actuation of at least one switch 430 if the switch 430 is facing a relief 205 and the support allows a contact between the relief 205 and the switch 430. The locking of the initial rotational position is achieved, for example, by the implementation of a set of mechanical non-return devices for rotating the housing 40 in a direction only with respect to the support piece 20. At each non-return, the switches 430 are positioned facing, or not, reliefs 205. In variants, at least one information representative of the number of switches opposite a relief is positioned on the contour of the support member 20, a relief on the periphery of the housing 40 moving with the rotation of the housing 40 to be placed opposite said information.

In variants, at least one switch 430 is associated with a rod 435 configured to press said switch 430 when a relief causes a displacement of the rod 435. These variants make it possible to implement smaller reliefs on the support piece 30. These variants allow, in addition, to enlarge the support area of the relief 205, making it possible to actuate the switch 430 even when the housing 40 is not located strictly opposite the relief. These variants also make it possible to reduce the size of the relief 205 in the support piece 20. The last advantage of these variants is to give the user a leverage effect: the rod 435, which causes the switch to be pressed on the switch 430 , this moves more than the stroke of the housing 40. This last advantage has two implications: on the one hand the user presses less on the housing 10 to activate the switch 430 and on the other hand, the switch 130 can still to be closed even when the race of the housing 10 in the support 20 is insufficient. The holding means 440 is, for example, a curved flexible blade configured to be twisted when a support is provided on the housing 40 by a user.

In variants, the housing 40 does not include a sensor 415 and a detector 420 and comprises means for receiving, such as an antenna, a signal comprising a message representative of the detection of a risk and / or presence issued by an alarm center or a remote risk detector.

In other variants, the housing 40 comprises a switch 430 perpendicular to the plane defined by the support part 20, the relief 205 comprises at least a portion perpendicular to the plane of the base opposite the switch and the connection deformable allows a rotation of the housing 40 about an axis generally perpendicular to the plane formed by the support part 20. In such variants, the rotation of the housing 10 closes the switch 130, controlling a function of the detector 50.

FIG. 3 shows one embodiment of the support piece 20 of the present invention. This support piece 20 is similar to the support piece 20 described with reference to FIG.

The support piece 20 is, for example, a ceiling base having a hollow housing and an opening 220 for the passage of the housing 10 in the housing. This housing forms a guide in translation of the housing 40 limited at one end by the support member 20 and at the other end by a stop, not shown.

In variants, the stop, not shown is an embodiment of a fixing of the housing 10 to the support member 20, the displacement of the housing 10 in the housing, forming a guide in translation, being an embodiment of the connection deformable 215.

In variants, the link 440 retains the part at least in its outward movement of the opening 220. These variants make it possible to dispense with the holding stops 135 and 225. In other variants, the deformable connection 440 and the deformable connection 215 are made by the same piece.

The support piece 20 further comprises a relief 205 positioned in the housing, this relief 205 being a long shape such as a rod, for example, oriented towards the opening of the support member 20. This relief 205 is positioned opposite an opening of the housing 10 when the housing 10 is inserted into the housing.

The support piece 20 is fixed to a wall 30, such as a ceiling, for example, by the fixing means 210. This fixing means 210 is, for example, a screw passing through an opening of the support piece 20.

The support piece 20 is fixed to the deformable connection 440, such as a spring or a flexible blade for example, by a fixing means 225. When the deformable connection 440 is a spring, this fixing means is, for example, a clip 225 in the support piece 20. When this connection is a flexible blade, this strip is, for example, molded in the support part 20 and the device does not include fixing means.

In other variants, the housing comprises several switches 130, the support part 20 has several reliefs 205, several deformable links 215 and has a little play in the directions perpendicular to the translational movement of the housing 10 in the support part 20 In these variants, depending on where the user presses the housing, one or more switches will close activating one or more functions of the detector 50.

FIG. 4 shows a particular embodiment of the detector 60 which is the subject of the present invention. This detector 60 is similar to the detector 50 described with reference to FIG. This detector 60 comprises a housing 10 and a support piece 20, the housing 10 being fixed to the support piece 20 by a bayonet type mechanism. This mechanism comprises, on the one hand, a set of protuberances 510 on the housing 10, these protuberances 510 being positioned at one end and on a lateral face of the housing 10, these protuberances 510 are called "male connectors". On the other hand, the support member 20 comprises a set of protuberances 505 roughly parallel to the general plane formed by the support member 20. These protuberances 505 are called "female connectors". To assemble a male connector to an associated female connector, the male connector is first positioned between the female connector and the base of the support piece 20 and then the housing 10 is rotated so that the male connector is in contact with the female connector and that the housing 10 can no longer be moved in rotation.

A housing between the female connectors and the base of the support piece 20 makes it possible to drive the casing 10 into the support piece 20. When the casing 10 takes up a so-called "rest" position, during which the male and female connectors females are in contact under the effect of the deformable connection 515, the positioning of these connectors is facilitated by complementary reliefs positioned on these connectors.
