[0001] This invention relates to a reminder device for use in the field of safety test data,
expiry dates or sell-by dates and the like.
[0002] Health and safety regulations often require electrical appliances or safety equipment
to be tested periodically. It is known to use stickers or labels on appliances to
show the last and/or next test date. However, these can become worn, displaced or
otherwise damaged during use of the appliance, whereby the date information may be
lost or rendered illegible. Bar code systems have also been used for collating test
date information at a central location. However, such systems can be impractical if
the appliance is portable and re-location of the appliance for checking cannot be
assured.
[0003] It is an object of the invention to provide an alternative solution to the monitoring
of safety test dates or the like which addresses one or more of the above issues.
[0004] FR 2788610 discloses a single use timer device according to the preamble of claim 1. According
to one aspect of the invention, there is provided a reminder device as set forth in
claim 1.
[0005] The device incorporates a contact portion, for example a pad or button, which can
be pressed by a user, to actuate the status indicator. Preferably, the status indicator
incorporates an audio and/or visual alert.
[0006] In a preferred embodiment, a series of status indicators are arranged to be illuminated
when the contact portion is pressed by a user, dependent upon the proximity to the
predetermined date or time period. The device may incorporate a circuit, whereby a
red signal is provided if a pre-set test date or time period has elapsed. The circuit
may provide an alternative colour signal, such as an amber signal, if the pre-set
test date is imminent. In a preferred embodiment, the status indicator is configured
to provide its alert function only when the device is agitated, e.g. shaken or said
contact portion is pressed.
[0007] In one embodiment, the device is incorporated into a laminated structure, wherein
a circuit is provided on a substrate, such as a credit card type material or other
plastic or board member, and overlaid with a cover material, whereby an alert is provided
when a particular portion of the card is pressed and said date or time period has
elapsed and/or is due to elapse in the immediate short-term. In addition to the contact
portion, the laminated device can be configured to provide an appropriate alert if
the device is shaken or otherwise agitated. The status indicator preferably comprises
an LCD.
[0008] The device is intended to operate for only a single time period and cannot be reset,
so as to be disposed of after use. These devices are preferably tamperproof, wherein
access to the internal components, for example to reset the timer, is not possible
without breaking into the device.
[0009] In a preferred embodiment, the device comprises a plastics base having or defining
a recess or chamber for the internal components. The device or recess preferably has
a peripheral lip, flange or other surface onto which a plastics cover can be heat
sealed, so as to permanently encase the internal components in the recess. At least
a portion of the cover is preferably transparent, e.g. in the region of the status
indicator. The contact portion is preferably visible through the cover. The device
may be configured so that the contact portion can be actuated by pressing the overlaying
portion of cover. Alternatively, the cover may have one or more apertures, e.g. over
the contact portion. The device may comprise a heat sealed plastics moulding, wherein
only the contact portion and/or status indicator is exposed.
[0010] The device includes means to start the counter cicuit, for example a pull-out tag
of known construction, which will effectively initiate a countdown for a single predetermined
time period, for example 12 months, 3 months or 6 weeks.
[0011] For 12 month devices, the unit will remain in standby mode once the countdown has
started. If the contact portion is pressed before the end of the countdown, a green
light will flash to indicate how many full calendar months are left in the countdown.
The unit will flash an amber light every 30 minutes and/or also if the contact portion
is pressed when there is less than a single calendar month remaining, the amber light
being replaced by a red light every 60 seconds when the unit has reached the end of
its countdown. Flashing will continue until the internal power source is exhausted.
The number of weeks since the countdown ended can be determined by pressing the contact
portion, whereupon a flashing red light will indicate the number of weeks. For 3 month
devices, the unit will remain in standby mode once the countdown has started. If the
contact portion is pressed before the end of the countdown, a green light will flash
to indicate how many full calendar months are left in the countdown. The unit will
flash an amber light every 30 minutes when there is less than 10 weeks or 70 days
remaining, replaced by a red light every 60 seconds during the last 12 weeks of the
countdown period. Again, flashing will continue until the internal power source is
exhausted, and the number of weeks since the countdown ended can be determined by
pressing the contact portion, whereupon a flashing red light will indicate the number
of weeks.
[0012] For 6 week devices, the unit will remain in standby mode once the countdown has started.
If the contact portion is pressed before the end of the countdown, a green light will
flash to indicate how many full weeks are left in the countdown. The unit will flash
an amber light every 30 minutes when there is less than 5 weeks or 35 days remaining,
replaced by a red light every 30 seconds during the last 6 weeks of the countdown
period. Again, flashing will continue until the internal power source is exhausted,
and the number of weeks since the countdown ended can be determined by pressing the
contact portion, whereupon a flashing red light will indicate the number of weeks.
[0013] The invention is advantageous in that it provides a convenient solution to problems
associated with co-ordinating safety test programmes for electrical appliances. The
device can be fitted to or adjacent an electrical appliance, and users of the appliance
are encouraged to interact with the device, e.g. via the contact portion, to determine
whether the appliance is due for testing.
[0014] The test history of vehicles and/or parts thereof can also be monitored using the
invention, hi particular, the invention has advantageous application for the testing
of HGV cabs and trailers and other vehicles which need to undergo regular checking,
wherein the driver of the vehicle can use a cab-mounted device to determine whether
the cab or trailer has exceeded a safety test deadline.
[0015] The invention is of particular use for the health and safety testing of electrical
appliances, but also fire extinguishers and the like, as well as office or laboratory
equipment. It can also be used to remind users of calibration deadlines for testing
hospital equipment, and also for indicating sell-by/expiry/destruction dates for consumables,
for example. The invention can be readily incorporated into refrigeration units.
[0016] Other features of the invention will be readily apparent from the claims and the
following description of preferred embodiments of the invention, which is made, by
way of example only, with reference to the accompanying drawings, in which:
Figure 1 is a schematic perspective view of a safety reminder device and its holder;
Figure 2 shows the device of Figure 1 attached to an electrical cable;
Figure 3 shows an electrical plug incorporating the device of Figure 1;
Figure 4 shows the device of Figure 1 attached to a fire extinguisher; and
Figure 5 shows the device and holder of Figure 1 mounted on a computer monitor.
[0017] Referring firstly to Figure 1, a reminder device is indicated generally at 100 consisting
of a moulded plastics body 102 in which is mounted a contact button 104 and a status
indicator 106.
[0018] A control circuit (not shown), preferably including a processor, is mounted in the
body 102, e.g. beneath the button 104 and status indicator 106. The control circuit
preferably includes a timer which can be activated to begin a count down for a predetermined
or pre-programmed time period. Alternatively, a electronic calendar can be incorporated
for monitoring a predetermined time period, for example 6 weeks, 3 months, 6 months,
or 12 months. In either case, the control circuit is configured to provide an alert
via the status indicator 106 when a predetermined date or time period has elapsed
and/or is close to elapsing.
[0019] In the illustrated embodiment, the status indicator 106 incorporates three LEDs arranged
to indicate a green signal if the stored date or time period has yet to elapse, a
yellow signal if the stored date or time period has almost elapsed (for example within
two weeks of the elapsed date), and a red signal if the date or time period has elapsed.
[0020] A power source in the form of a lithium battery (not shown) is mounted in the device
100 for powering the control circuit.
[0021] To conserve power, the control circuit is configured to illuminate the LEDs only
when the contact button 104 is pressed by a user. Alternatively or additionally, it
may be configured to intermittently illuminate the amber LED as the elapse date or
the end of the predetermined time period approaches and/or to permanently or intermittently
illuminate the red LED when the particular date has elapsed, for example. The frequency
of red illumination is preferably higher than the frequency of amber illumination.
[0022] The device 100 is supplied in a pre-set state, so as to be operable for one or more
fixed periods, e.g. for indicating a red light on the status indicator after a 6 month
period. The devices 100 includes a pull-out tab 118, for use in activating the countdown
function of the control circuit.
[0023] The device 100 is formed as a robust and sealed unit, whereby access to the internal
components of the device 100 is substantially inhibited. It is preferred if the body
102 is tamperproof, e.g. formed in such a manner as to provide a unitary, single piece
housing around the internal components, to prevent access to the internal components
without smashing or otherwise breaking into the device. Hence, such units are typically
factory set, whereby the timer circuit is preferably non-resettable.
[0024] As can be seen in Figure 1, the body 102 defines an upper periphery around the button
104 and status indicator 106 in Figure 1. The periphery delimits a recess into which
the internal components are fitted. In a preferred embodiment, a transparent cover
(not shown) is heat sealed or otherwise permanently affixed onto the body 102, whereby
to encase the button 104 and status indicator 106 in the device. The cover may be
a sheet or film of preferably plastics material. The device 100 is preferably arranged
so that the contact portion can be actuated by pressing the overlaying portion of
cover. Alternatively, the cover may have an aperture over the contact button 104.
However, access to the internal components, for example to reset the timer, is not
possible without breaking the cover or base 102. The device 100 is intended to be
disposed of after use and may be broken down and recycled.
[0025] The device 100 can be removably received in a holder 110 by a friction fit, for example
using inter-engaging ribs and grooves between the device 100 and its holder 110, or
a clip or snap-fitting engagement. In the illustrated embodiment, the holder 110 includes
a nib 112 adapted to snap-fittingly engage in a detent 114 on the body 102. The holder
100 can then be secured to a desired location, for example on an appliance so that
the device is portable with the appliance.
[0026] The device 100 can be fitted to or adjacent an electrical appliance, and users of
the appliance are encouraged to press the contact button 104 on the device 100 to
determine whether the appliance is due for testing.
[0027] If the button 104 is pressed and the status indicator 106 remains inactive, the user
must assume that the power source for the device 100 is inactive. A telephone number
or other contact address can be provided on the unit, for example on data bar 116
on the front of the device 100, for reporting that the device is faulty. An additional
panel for signature by a test engineer and or space for a conventional barcode may
also be included on the device or holder.
[0028] Several suitable applications for the device are indicated in Figures 2 to 5. In
Figure 2, the device 100 is shown secured to an electrical cable 120 via a cable tie
122, so as to travel with the cable 120 for permanent association with the cable and
any appliance or plug connected at the ends of the cable. In Figure 3, the device
100 forms an integral part of an electrical plug 130. The device can be removably
received in the plug head if desired. In Figure 4, the device is secured to a safety
extinguisher 140 using a tether 142, although it may also be formed as an integral
part of the extinguisher housing or handle. In Figure 5, the combination of device
100 and holder 110 is shown fitted to a computer monitor 150.
[0029] Although shown in triangular form in the Figures, the device 100 may take any suitable
shape and construction. However, the device 100 and/or its display will typically
be no larger than the body of a conventional wristwatch, credit card or pager.
[0030] The most preferred embodiments are intended to be tamperproof and non-resettable,
other embodiments may utilise a body which can be opened only using a unique and dedicated
key or other such mechanism, so as to enable only authorised persons to access the
control circuit, for example for re-setting or maintenance.
[0031] A solar cell may be incorporated in the device 100 to supplement or replace the batteries.
An LCD display may also be incorporated for displaying pre-programmed messages or
other data to users, for example when the contact button 104 is pressed or if the
test deadline has elapsed. Such messages may include a name or number for contact
to arrange re-testing of the associated appliance, for example.
[0032] The invention has thus far been described as having a status indicator 106 which
is activated when the contact button 104 is pressed by a user. The button may take
the form of an object which can be physically depressed relative to the housing. However,
it may take the form of a simple contact pad, tab or other such contact portion, whereby
in each case, the control circuit is initiated to provide an appropriate alert via
the status indicator, if necessary, if a user presses the contact portion.
[0033] A plurality of buttons may be included which must be pressed in a predetermined manner,
e.g. together or in sequence, in order to cause activation of the status indicator,
thereby to reduce power consumption and to deter intermittent intervention from casual
or unauthorised users.
[0034] In those embodiments where the device is removable from a holder, the power source
can be integral with the holder, and may take the form of a solar panel and/or a piezoelectric
power source which generates power upon agitation of the holder. These power sources
may alternatively be incorporated into the body of the device.
[0035] In a further embodiment, the device or its holder incorporates a transmitter for
transmitting status information to a remote location. A transceiver can be incorporated,
whereby the device can be remotely activated and/or reset. The transceiver can also
be used for indicating the position of the device, for example if the device is secured
to or integral with a portable or movable object.
