The invention relates to an office workplace system, intended to be used together with an office desk, comprising a sound reducing and/or absorbing screen.
Sound reducing and/or absorbing screens are described in for instance WO 2014/143861 A1. Such screens are placed around the back and/or sides of an office desk, on which further a computer display and keyboard are usually present, in order to provide privacy and sound reduction in an office environment. Several ergonomic issues play an important role in the workplace, such as sound (including noise), the visual work environment, privacy, the physical working position, and the readability of the display in view of glare. The invention aims at improving one or more of these conditions.
To that end the system comprises a vertically extending frame with a base arranged to be placed on, or fixed to, a floor, a wall, a ceiling or a desk top; a sound reducing and/or absorbing screen, wherein the screen is elongated in shape, the front surface of the screen and the short edges of the screen extend vertically and the long edges of the screen extend horizontally; wherein the frame is arranged to hold the screen at a height relative to the floor, the wall, the ceiling or the desk top; wherein the frame is provided with means to adjust the height of the screen relative to the base of the frame; and wherein the system is dimensioned such that the lower edge of the screen is allowed to extend higher than the height of the top front surface of an office desk with which the system is used. Thereby the vertical dimension of the screen is allowed to be small, such that the user will not have the feeling of being locked away, but because it can be set at a desired height (typically users will set the centre to the height of the user's eyes and ears when sitting or standing at the desk) it will be effective for reducing sound.
In a preferred embodiment the system further comprises a computer display mount for holding at least one computer display; wherein the frame holds the display mount at a height relative to the floor, the wall, the ceiling or the desk top; wherein the frame is provided with means to adjust the height of the display mount relative to the base of the frame; and wherein the system is provided with means arranged to fix the relative height between the screen and the display mount while the height of the screen and the display is being adjusted. Thereby the display will automatically be moved up and down with the screen, to the ideal height where the display is more or less at the same height as the user's eyes when sitting or standing at the desk. This solves the problem that computer displays are usually set too low by users, which may result in a wrong physical working position. Preferably said means arranged to fix the relative height between the screen and the display mount are arranged to fix the display mount at or against the centre of front surface of the screen, such that the centre of the display mount is always at the same height as the centre of the screen front surface. Preferably said computer display mount is arranged to hold two computer displays horizontally next to each other. The computer display may be a separate device, but it may also be part of a laptop or a tablet, etc., and it may be a touchscreen.
Preferably said screen has a central part which is substantially flat and two lateral side wings of which the front surfaces face each other and extend approximately perpendicular to the front surface of the central part. Thereby the front side of the user will be more or less surrounded by the screen, and a computer display located between the wings will suffer less glare.
The horizontal cross sections of the connecting front surface between the side wings and the central part are preferably curved. The vertical cross sections of the front surface of the screen are preferably curved near the upper and lower edges. The front surface of the screen is for instance formed by a sound insulating and/or sound absorbing padding, such as a 5-30 mm thick padding, for instance made of polyether foam, optionally covered by a fabric. The frame may also be covered by such padding.
The system is preferably dimensioned such that the height of the centre of the screen can be adjusted to at least two different heights in the range of 20 cm and 60 cm above the top front surface of an office desk with which the system is used. If the base of the frame is arranged to be placed on a floor, the system is preferably dimensioned such that the lower edge of the screen is allowed to extend higher than 70 cm above the floor, if said base is placed on said floor. If the base of the frame is arranged to be placed on, or fixed to, a desk top, the system is preferably dimensioned such that the lower edge of the screen is allowed to extend higher than the top front surface of said desk top, if said base is placed on, or fixed to, said desk top. The distance between the front surfaces of the lateral side wings is preferably between 100 and 140 cm, such that for instance two computer displays of 24 inch can be placed horizontally next to each other between the wings. The height of the front surface of the screen is preferably between 30 cm and 60 cm.
The frame preferably comprises a vertically extending plate comprising one, two or more vertical slots in which the screen is slidably mounted. Said means to adjust the height of the screen relative to the base of the frame preferably comprise a spring or a counterweight which exerts an upward force to the screen which is at least equal to approximately the total weight of the height adjustable parts of the system including the screen.
The invention will now be illustrated by means of a preferred embodiment, with reference to the drawings, wherein:
With reference to
The frame 1 comprises a front panel 11 and a back panel 12. The screen 2 with the displays 3 are adjustable in height by means of a height adjusting mechanism, comprising two mounting brackets 42 to which the screen 2 is mounted, said brackets being slidably mounted in two vertical slots 47 of the frame 1. The slots 47 are provided with a mounting profile 46 with linear slides 43 on each side thereof for guiding the mounting brackets 42. At the top of each slot 47 a housing 44 is attached inside the frame 1 to the mounting profile 46 in which a (constant force) spring 45 is mounted, the end of which is connected to the respective bracket 42. The force of the spring 45 is approximately equal to the weight of the screen 2, the two displays 3 and the display mounts. The frictional force between the brackets 42 and the slides 43 is enough to hold the screen 2 with the displays 3 in the desired height position. A grip 41 is mounted to the screen 2, such that a user can easily adjust the height of the screen 2 with the displays 3.
The screen 2 has a flat central part 21 and two lateral side wings 22, which extend perpendicular to the central part 21. The connecting parts between the side wings 22 and the central part 21 are curved. Also the upper and lower edges of screen 2 are curved towards the back side. The front surface of the screen 2 is formed by a sound insulating and sound absorbing padding, such as a 15 mm thick polyether foam, which is covered by fabric.
