Description

Title: a display screen device
Description:
The present disclosure relates to a display screen device.
EP3516286 discloses a display screen device with wheels for moving the device in a rolling manner over a ground surface and a brake. The brake is arranged for braking one or more of the wheels such that the device is movable only if the display is near or in the lowest position. Allowing the device to be only moved when the screen is near or in the lowest position is beneficial for reducing the risk of the device tipping over.
The display screen device according to the present disclosure comprises a base unit provided with wheel elements for supporting said display screen device, via said wheel elements, on a ground surface. The display screen device is movable in a rolling manner. The display screen device is movable by means of the wheel elements, for example between different rooms. If the display screen device is used in a school environment, the display screen device can be moved between different classrooms.
The display screen device according to the present disclosure furthermore comprises a display screen unit and a lift unit, said lift unit being connected to said display screen unit and said base unit, arranged for adjusting a distance in a height direction between said display screen unit and said base unit.
The display screen device according to the present disclosure also comprises a brake arrangement arranged for, in a first state of said brake arrangement, braking at least one of said wheel elements and arranged for, in a second state of said brake arrangement, allowing movement of said display screen device in a rolling manner over said ground surface. The display screen device is thereby prevented from being moved when the brake arrangement is in the first state.
The display screen device according to the present disclosure yet further comprises a controller arranged for determining said distance in said height direction between said display screen unit and said base unit and controlling said brake arrangement such that said brake arrangement is in said first state when said distance exceeds a predetermined distance and wherein said brake arrangement is in said second state when said distance is equal to or smaller than said predetermined distance. By configuring the controller such that the at least one wheel element is released if said distance in the height direction is equal to or smaller than said predetermined distance, it is ensured that the display screen device is movable if the display screen unit is below a predetermined height above said base unit. Movement in a higher position is then prevented as the brake arrangement is in the first state.
When said distance in the height direction is equal to or below said predetermined distance, a relative stable display screen device is realised, whereby the risk of unwanted tipping over of the display screen device is relatively low. In the relatively unstable higher position of the display screen unit (higher centre of gravity), movement is then prevented.
The display screen device further comprises a user input device arranged for receiving override input for overriding said controlling, wherein said override input is related to any of: - assuring that said brake arrangement is in said first state when said distance is equal to or smaller than said predetermined distance; - assuring that said brake arrangement is in said second state, preferably during a predetermined time period, when said distance exceeds said predetermined distance; wherein said controller is arranged to override said controlling based on said received override input.
By providing the user input device that is arranged for receiving override input a relative versatile display screen device as regards movement of the display screen device is realised while maintaining a relative safe display screen device as regards the risk of tipping over.
Within the context of the present disclosure an override is to be understood as a functional feature of the display screen device where control is taken, via the user input device, over the controller and the brake arrangement such that an override of the controlling, by the controller, of the brake arrangement according to which the brake arrangement is in said first state when said distance exceeds said predetermined distance and in said second state when said distance is equal to or smaller than said predetermined distance is, at least temporarily, no longer executed.
Assuring that said brake arrangement is in said first state when said distance is equal to or smaller than said predetermined distance is beneficial for reducing the risk of unintendedly moving the display screen device for instance when leaning against the display screen device. An unintended movement of the display screen device may for instance result in the leaning person to falling over and thereby causing injury or damage to the display screen device for instance due to tipping over of the display screen device.
Assuring that said brake arrangement is in said second state, preferably during a predetermined time period, when said distance exceeds said predetermined distance is beneficial for avoiding the need for reducing the distance in the height direction between the screen unit and the base unit to allow moving of the display screen device.
It may occur that a user of the display screen device requires a movement of the display screen device, during use, for instance when presenting, to direct the screen to a specific part of the crowd or class room. Requiring said distance to be equal to or smaller than said predetermined distance may result in a relative long interruption and thereby to a relative unsatisfactory user experience.
In an embodiment of the display screen device according to the present disclosure, said controller is further arranged for controlling said brake arrangement such that said brake arrangement is in said second state when said distance is equal to or smaller than said predetermined distance and said display screen unit is turned off. Thus, the brakes are released when the display screen unit is in a low position and said screen is shut off. This has the benefit that a user can move the display screen unit in a safe manner.
In another embodiment of the display screen device according to the present disclosure, said user input device is further arranged for receiving an operation mode input, wherein said operation mode input is related to assuring that said brake arrangement is in said second state when said distance is equal to or smaller than said predetermined distance and said display screen unit is turned off. This allows the user to send input to the display screen device so that the possibility to move said display screen device corresponds with the input provided by said user.
Preferably, said display screen device comprises a tilt unit arranged for adjusting a tilt angle between said display screen unit and said ground surface, said controller further arranged for controlling said brake arrangement such that said brake arrangement is in said first state when said tilt angle is equal to or smaller than a predetermined tilt angle.
Preferably, said predetermined tilt angle can be in the range of 80 degrees to 90 degrees, preferably 90 degrees. Thus, the brakes are engaged when the tilt actuator is not in a vertical position. This prevents unintended movements of the display screen device and thereby causing injury or damage to the display screen device for instance due to falling over of the display screen device, for example when a user leans on the display screen unit.
In another embodiment of the display screen device according to the present disclosure, said tilt unit is arranged for adjusting said tilt angle in a range between 0 degrees and 90 degrees. This allows the user to use the display screen unit in different positions, ranging from a completely vertical to a completely horizontal position.
Preferably, said user input device is further arranged for receiving a further operation mode input, wherein said further operation mode input is related to assuring that said brake arrangement is in said first state when said tilt angle is equal to or smaller than said predetermined tilt angle. This allows the user to send input to the display screen device so that movement of said display screen device in a rolling manner is prevented, which corresponds with the input provided by said user.
Preferably, said display screen device further comprises a switch for further controlling said brake arrangement, said controller further arranged for controlling said brake arrangement such that said brake arrangement is in said first state when said switch is in a first position and said display screen unit is turned off and such that said 5 brake arrangement is in said second state when said switch is in a second position and said display screen unit is turned off. With the switch, the user can place the display screen unit in the desired position, i.e. the height of said display screen unit, by moving said display screen unit up- or downwards using said switch.
Preferably, said switch also has the functionality of turning on and off the display screen. This is beneficial for avoiding the need for providing a relative large number of switches on the display screen device.
Preferably, said display screen device comprises a battery unit, coupled to said brake arrangement, arranged for powering said brake arrangement such that said brake arrangement is in said second state when said switch is in said second position and when said display screen device is disconnected from a mains power supply. If the lift is equipped with a battery and the mains power is disconnected and the lift is in its lowest position, the up/down switch can be used to engage/release the brake.
This allows to safely park the display screen device with the brake on.
Preferably, said display screen unit is a touch screen or is provided with a touch frame and said user input device is arranged for receiving said overriding input, said operation mode input and said further operation mode input via said display screen unit or said touch frame. Firmware settings and activation of the actuators can be controlled by software in the touchscreen.
Preferably, said brake arrangement comprises a movable braking element which is configured to grip, in said first state of said brake arrangement, onto said at least one of said wheel elements. The brake may comprise interlocking teeth in the wheels and a locking pad. With this arrangement, the display screen device can be safely used without the risk of accidental moving of said display screen device, for example when a user leans on the display screen unit.
Preferably, said brake arrangement further comprises an actuator for moving said movable braking element between a first position wherein said braking element grips onto said at least one of said wheel elements and a second position wherein said braking element is free from said at least one wheel element. With said actuator, the user can manually control the braking elements and thus, manually control moving the display screen device.
Preferably, said actuator is provided inside said base unit.
Preferably, said predetermined distance corresponds to a smallest distance in a height direction between said display screen unit and said base unit.
Preferably, said predetermined time period is in the range of 5 seconds to 60 seconds. After said predetermined time period, the brake arrangement will be in the first state thereby preventing said display screen device to be moved. Said predetermined time period ensures that the brake arrangement will be in the second state for a limited time period, so that in case it is forgotten by the user to position the brake arrangement in the first state after parking said display screen device, said brake arrangement will automatically switch from said second state to said first state so that said display screen device is safely parked.
