SE507459C2 - Holder for notice for fixture to wall or notice board - Google Patents

Abstract

The holder is provided with a device (31) for feed-out of gripper for notice arranged on a shaft (9). The holder is provided with a device for selective adjustment of the time period a notice is required to be located in a visible position. The holder is positioned with a light indicator which shows that the notice suspended in the grippers is newly inserted. The shaft is set in rotation by a motor or by a spring (27) on the expiry of the time-adjusted period for showing the notice, automatically rolling up the notice into a concealed position in the holder. A concealed notice (4) rolled onto the shaft can be unrolled from the holder by reversible drive of the motor.

To prevent the impact from rolling in and disappearing just when someone is studying an impact, the device is equipped with a photocell. The task of the photocell is to give a signal to the control electronics to wait to roll in the stop after the end of the set time, until it is quite dark, ie a small amount of light falls on the photocell. In this way, appropriations will not be rolled into the device when someone is studying appropriations, as it is unlikely that appropriations will be studied when it is dark at the appropriation.

In some cases, it is not possible to wait to roll in the grant until it gets dark.

An example of this is that in certain workplaces or public spaces where there is always a certain amount of light, so-called. led light. In these cases, it may be better for the grants to be removed at a certain time, for example at 03.00 or another time when it can be expected that there are few or no people studying grants. To realize such a timed removal of stops, the device is provided with a clock which contains the correct time.

The task of the clock is to give a signal to the control electronics to wait to roll in the stop immediately after the end of the set time, until the clock is, for example, 03.00. In some cases, it is better to replace the photocell and the watch with a motion detector.

The motion detector registers the presence of a person in front of the holder, and thus prevents a grant from being rolled in when a person studies the grant.

The task of the motion detector is to give a signal to the control electronics to wait to roll in the stop immediately after the end of the set time, until no person is standing in front of the holder.

In the accompanying drawings, the holder is illustrated according to the invention.

By (1) is indicated in the drawings a holder, arranged to be mounted on a notice board or the like by means of fastening devices (2). A rotatable shaft (9) is provided in the holder, provided with gripping devices (3) intended to be rolled out of the holder and to grip a stop (4) and hold it in a visible position under the holder. This is done in a simple way by pressing button (5). At the same time as the gripping devices (3) are attached to the stop (4), a lamp (13) is lit and suitably indicates with flashes that the stop has been set up recently. By means of a time setting means (6) a time period is selected for the stop (4) to sit up, i.e. how long the grant is deemed to be relevant. The lamp (13)'s indication that the stop is newly installed may last for a few days. The control thereof preferably takes place by means of a timer (12) via a signaling device (25). In an indicator field (8) on the holder, the time and the day on which the stop was set up are indicated.

The gripping devices (3) are mounted on a shaft (9) and the shaft (9) can be set in rotation by an electric motor (10). It is possible to roll up a fixed stop (4) around the shaft (9) by letting the motor (10) run. The rotation of the shaft (9) is started after the set time on the adjusting means (6). The rotation of the shaft (9) continues until the entire stop (4) has been wound up around the shaft (9). In order for the holder to know with certainty that the entire stop has been rolled up, a control electronics (11) ensures that the motor (10) is allowed to run considerably further than what may be necessary to roll up a stop. By letting the motor (10) run excessively long, no sensor is needed which signals to the control electronics (11) that the stop (4) is completely wound around the shaft (9).

When the set time has elapsed, the motor (10) starts and the stop (4) is rolled in the holder.

The grant is now hidden. Through this arrangement, obsolete appropriations are hidden, and only current appropriations are displayed on the notice board.

When setting up a new stop, press the button (5). Due to this depression, the motor (10) will go reversible, which means that the wound stop (4) will be rolled off the shaft (9) and when this is done it can be removed and thrown away, after which a new stop can be attached to the gripping devices (3 ). 507 459 10 15 20 25 30 35 Figure 4 shows an electrical block diagram of an embodiment of the invention consisting of a timer (12), actuator (6) for setting the timer, a lamp (13), drive stage (14) for the motor ( 10), actuators (5) for reversible operation of motor (10), detector (15) and a logic "and" element (16). The holder is powered by a battery (17).

When a new stop is to be set up, the control button (5) is activated, which gives a signal | (18) to the drive stage (14). The signal (18) causes the motor (10) to start reversibly. The old stop is thus rolled out of the holder. The new stop is attached, and the time is set on the actuator (6), how long the stop should sit up via the signal (19) to the timer (12). The timer (12) turns on and flashes the light (13), which indicates that the stop has just been set up. The lamp signals a specific time. After the set time, the timer (12) signals that the set time has expired with the signal (20). To prevent the stop from being rolled in just when someone is studying the stop (4), a logic "and" element (16) placed between the motor control (14) and the timer (12) "time out" sign | (20). In order for the stop to be rolled in by the signal (20), it is also required that the detector (15) signal (21) does not register that any person is standing and reading a stop. The detector (15) may consist of a motion detector, photocell or a clock, the various functions of which have been described. When the "and" condition is true, the signal (22) is given, at which point the motor (10) starts to roll up the stop. The timer (12) ensures that the motor stops after a certain time by removing the signal (20). 15) should not be able to prevent a stop "for any length of time" from remaining after the set time has elapsed, there is a "timeout" function in the timer (12) which unconditionally starts the engine with the signal (23).

The heating is powered by a battery (17) or solar cells.

In case a steel spring and a solenoid (pull magnet) are used, the solenoid is connected to the signal (24). Figure 2 shows an embodiment in which the gripping device (3) is replaced by a fastening cloth (26) which has been mounted fixedly on the shaft (9). Of course, the design with a fastening cloth (26) is not limited to the design in fi g. 2, without fastening cloth (26) can advantageously also be used in the embodiment shown in fi g. The function of the fastening cloth (26) is that the stop (4) to be set up is fastened to the fastening cloth (26). By using a fastening cloth (26) three advantages can be achieved: 1. The motor of the holder (10) can be replaced by a tent spring (27) and a soenoid (28). The steel cap (27) is tightened when a new stop is to be set up by pulling the fastening cloth (26) out of the holder with handles (31) and blocking it from being rolled up again from a catch (30) (in a similar way as in a normal blind) .

The latch (30) is controlled by the solenoid (28). After the set time has elapsed, the control electronics (7) give a signal to the sonoid (28) to release the latch (39) to the axis (9). The shaft (9) will then start to rotate by using the stored energy in the steel cap (27) and thus roll up the fastening cloth around the shaft (9). The roll-off stops at the end stop (32). 2. The holder becomes less dependent on the size of the stops (4), because as long as the stop is smaller than the fastening cloth (26), the stop can be taped anywhere on the cloth (26). To make the set-up even easier, the fastening cloth (26) is made of a semi-sticky material so that the stops (4) are only pressed onto the cloth (26). In this way, no tape or other fastening devices are needed to fasten the stops (). 3. The holder can be made as a mechanical construction, ie without electronics, which can be an advantage in some cases.
