TECHNICAL DOMAIN

[0001] The present invention concerns an improved screen device with a power interrupt switch.

BACKGROUND

[0002] With motorised screen devices, the motor and/or the screen is often shielded by means of a housing or a protective casing against undesirable outside influences such as moisture, dirt, wind, rain, human intervention etc.

[0003] Document EP2354430A2 from prior art concerns a screen device, which comprises, a rolling up and a rolling down screen, a motor for the driving of the rolling up and the rolling down movement of the screen, a fastening body, to which the far end of the motor is attachable via a linear sliding movement, whereby said far end of the motor comprises a fastening head, which is attachable to the fastening body to attach the motor to the fastening body, an electric power supply cable comprising one or more electric wires, for the supply of electric power to and/or the earthing of one or more electric wires of the motor and an electrical coupling for the electrical connecting of the electric wires of the electric power supply cable to the electric wires of the motor. In the document mention is made of a housing to incorporate the motor.

[0004] A problem with the known screen devices is that by installation or replacement the various actions to be carried out are not user-friendly and unsafe. The assembling and disassembling also often involve complicated actions. This often causes much lost time, which as a consequence thereof leads to additional costs. The screen devices, which are often set up at a relatively high position, necessitate an effective, ergonomic, user-friendly, reliable, safe and fast way of installation or replacement.

[0005] Also when, for example, windows require to be washed and a screen device hangs in front of the window, it is possible that during the washing of the windows the screen makes an undesirable and unexpected movement, for example, when controlled by third parties or a sun-wind sensor, and through this endangers the window cleaner. The invention has as an advantage that the electric current can be switched off by the window cleaner during his/ her work.

[0006] The purpose of the present invention is to provide a user-friendly, ergonomic, effective, reliable, safe and fast way of installation or replacement of a motorised screen device. The invention is also purposed to provide an improved method for the installing or replacement of such motorised screen devices.

[0013] In the first aspect, the invention concerns a screen device 1, comprised of a screen, a motor 3 for the driving of the rolling up and rolling down movement of the screen, which comprises one or more electric wires for the supply of electric power and/or the earthing of the motor 3 and which is connected to said screen, an electric power supply cable 5 which includes one or more electric wires for the supply of electric power to and/or the earthing of the one or more electric wires of said motor 3, a housing 12, which comprises a fastening body 4 and which shields said motor 3, said motor 3 attached to said fastening body 4 and a switch 40, whereby the switch 40 is provided with an on and off position, whereby in the on position electric power can be supplied to the motor 3 via the electric power supply cable 5, whereby in the off position the electric power supply to the motor 3 is interrupted, whereby said switch 40 is situated near to the motor 3, the fastening body 4 or the housing 12 and whereby said switch 40 is such constructed to interrupt the electric power when accessing the motor 3.

[0014] This has as advantage that the user can interrupt the electric power to the motor 3 in an easy, safe and fast manner. In the event of a manual switching on and off of an electric circuit by the installing of the motor 3, this presents an uncontrollable risk through the actions of third parties. If this switch 40 is provided at a strategic location, then a user-friendly, reliable and fast switch-off of the electric power supply can take place. Moreover, the actions of installation or replacement of the motor 3 by the user takes place in a safer manner since the electric power supply can be interrupted by means of a simple switching and can thus be interrupted in an uncomplicated manner. This also has as an advantage that a much greater degree of safety is achieved than, for example, the manually switching on and off of an electric circuit by the installing of the motor 3. In that said switch 40 is located near to the motor 3, the fastening body 4 or the housing 12, the installation or replacement of a motor 3 can take place without the undesirable influence of third parties. In this manner third parties have less of a possibility to unintentionally or mistakenly supply the motor 3 with electric power. The probability of electrocution or an accident through a becoming operational of the motor 3 greatly decreases. The switch 40 is also situated more conspicuously, which increases the safety for the fitter. Also, this offers the possibility for a fast, more ergonomically responsible and reliable installation or replacement of the motor 3.

[0015] The term "switch" in the present invention, among other things, refers to a pressure switch, foil push button, slide switch, rotary switch, toggle switch, touch switch, mercury switch or reed switch.

[0016] The term "motion switch" in the present invention refers to a switch 40 which in part comprises a mechanical component.

[0017] In a preferred form of a device according to the invention, said switch 40 is situated on, to and/or in, the housing 12.

[0018] In that said switch 40 is situated on, to and/or in the housing 12, the installation or replacement of a motor 3 or the screen or another component within the housing 12 of the screen device, can take place without the unwanted influence of third parties. Third parties still have a lesser possibility to mistakenly provide electric power to the motor 3. The probability of electrocution or an accident through a becoming operational of the motor 3 decreases. This also offers the possibility towards a faster, more economically responsible and reliable installation or replacement of the motor 3 or the screen or another component within the housing 12 of the screen device.

[0019] In a preferred form of a device according to the invention, said switch 40 is included in the path of the electric power supply cable 5.

[0020] This has as advantage that there is a greater certainty by an interruption of the electric power supply from the motor 3. An indirect connected switch 40 does not have this advantage. A safer installation or replacement is possible.

[0021] In a preferred form of a device according to the invention, said switch 40 concerns a motion switch and said switch 40 comprises a relocation element.

[0022] This has as advantage that a simple relocation of an element allows a faster installation or replacement of a motor 3.

[0023] In a preferred form of a device according to the invention, the switch 40 is controlled by a hinge moment in said housing 12.

[0024] This has as an advantage that a rotating movement of the housing 12 promotes the actions of an installation or replacement of the motor 3 in a practical and ergonomic manner.

[0025] In a preferred form of a device according to the invention, the motor 3 and/or the screen is removable from the housing 12.

[0026] This has as an advantage that a faster installation or replacement of the motor 3 is possible. The housing 12 can thus remain hung at the window or wall which allows a cheaper installation or replacement of a damaged or malfunctioning motor 3 or the replacement of a damaged screen. In a preferred form of a device according to the invention, the motor 3 is detachable if the switch 40 is in the off position.

[0027] This has as an advantage that the detachment of the motor 3 or replacement of a screen or another component within the housing 12 of the screen device can preferably only occur if the switch 40 is in the off position and thus the motor 3 is not supplied with electric power. The impossibility of the motor 3 coming into operation and the lesser probability of electrocution increases the degree of safety for the fitter or the person effecting the replacement.

[0028] In a preferred form of a device according to the invention, the switch 40 when in the on position blocks the opening of the housing 12.

[0029] This has as an advantage that the housing 12 cannot be opened if the electric power is not interrupted. This increases the degree of safety for the fitter or the person effecting the replacement.

[0030] In a preferred form of a device according to the invention, the switch 40 comprises a blocking element that blocks the removal of the motor 3 or the replacement of a screen, preferably fully blocks same, if the switch 40 is in the on position.

[0031] This has as an advantage that a detachment of the motor 3 or the replacement of a screen cannot occur if the motor 3 is supplied with electric power. This is mechanically blocked. The impossibility of the motor 3 coming into operation and the lesser probability of electrocution increases the degree of safety for the fitter or the person effecting the replacement.

[0032] In a preferred form of a device according to the invention, the switch 40 comprises a reed contact 23 and a relocation element, whereby the relocation element comprises a magnet 24.The term "reed contact" in the present invention refers to an electrical switch contact in a glass tubule, which tubule is filled with an inert gas, that is operated by a magnetic field, originating from a magnet.
The term "magnet" in the present invention refers to a permanent magnet or a coil through which a current flows.

[0033] This has as an advantage that no or hardly any sparks arise on switching. This increases the degree of safety for the fitter or the person effecting the replacement. There is less possibility towards the wear of the switch 40 in that the glass tubule of the reed contact is filled with an inert gas, so that the switching of currents does not, or hardly, affect the switch contacts of the reed contact.

[0034] In a preferred form of a device according to the invention, the attachment head 15 is provided with guiding ribs 9 and the fastening body 4 is provided with guiding slots 8, which are suitable to attach the motor 3 to the fastening body 4 perpendicular to its axis by means of a linear sliding movement.

[0035] This has as an advantage that this promotes the ergonomics for the installing or replacement of the motor 3 or the screen.

[0036] In a preferred form of a device according to the invention, the attachment head 15 is provided with at least one bore 11 which is suitable for taking up a fastening means 10 and whereby the attachment head 15 to which the motor 3 is attached by a fastening means 10 can be held fast to the fastening body 4 whereby the head of the fastening means 10 is shielded by the relocation element of the switch 40 if the switch 40 is in the on position and whereby the head of the fastening means 10 is not shielded by the relocation element of the switch 40 if the switch 40 is in the off position.

[0037] This has as an advantage that a detachment of the motor 3 or the replacement of a screen can occur if the motor 3 is supplied with electric power. The impossibility of the motor coming into operation 3 and the lesser probability of electrocution increases the degree of safety for the fitter or the person effecting the replacement.

[0038] The term "fastening means" in the present refers to a means which is suitable to connect at least two bodies to each other, such as a bolt or a screw.
