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.
SUMMARY OF THE INVENTION
[0007] The invention concerns, in particular, a screen device, such comprised of a screen,
a motor for the driving of the rolling up and the rolling down movement of the screen,
which comprises one or more electric wires for an electric power supply and/or the
earthing of the motor and which is connected to said screen, an electric power supply
cable comprised of one or more electric wires for the supply of electrical power to
and/or the earthing of the one or more electric wires of said motor, a housing, which
comprises a fastening body and which shields said motor, said motor attached to said
fastening body by means of an attachment head on the motor and a switch, which is
provided with an on and off position, whereby in the on position electric power can
be supplied to the motor via the electric power supply cable, whereby in the off position
the electric power supply to the motor is interrupted, whereby said switch is situated

[0018] The quoting of numerical intervals by the endpoints comprises all integers, fractions
and/or real numbers between the endpoints, with these endpoints being included.
[0019] When in this document "approximately" or "about/ around" is used with a measurable
quantity, a parameter, a duration or moment, and suchlike, then variations of +/-20%
or less are to be understood as, preferably +/-10% or less, preferably more by +/-5%
or less, even more preferably by +/-1% or less, and still even more preferably by
+/-0.1% or less than and of the quoted value, in so far such variations are applicable
to the invention as described. Here it should however be understood that the value
of the quantity whereby the term "approximately" or "about/ around" is used, is itself
specifically indicated.
[0020] 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 on access to the motor
3.
[0021] 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.
[0022] 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.
[0023] The term "motion switch" in the present invention refers to a switch
40 which in part comprises a mechanical component.
[0024] In a preferred form of a device according to the invention, said switch
40 is situated on, to and/or in, the housing
12.
[0025] 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.
[0026] 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.
[0027] 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.
[0028] 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.
[0029] This has as advantage that a simple relocation of an element allows a faster installation
or replacement of a motor
3.
[0030] In a preferred form of a device according to the invention, the switch
40 is controlled by a hinge moment in said housing
12.
[0031] 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.
[0032] In a preferred form of a device according to the invention, the motor
3 and/or the screen is removable from the housing
12.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] 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.
[0042] This has as an advantage that this promotes the ergonomics for the installing or
replacement of the motor
3 or the screen.
[0043] 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.
[0044] 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.
[0045] 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.
[0046] In a second aspect, the invention concerns a system for the constructing of a device,
comprising a screen, a motor
