Definitions
- the present invention relates to the field of ergonomics at a working place, for instance in respect of computerised work and then in particular in connection with image screen work.
- the diagnostic examination of the images of patients obtained by x-ray investigations, magnetic resonance imaging, and ultrasound investigations required significant concentration and is more or less stressful, depending on prevailing circumstances with regard to light functions and also to the ergonomic strain to which the viewer is subjected.
- U.S. Patent Specification 5,339,750 teaches an adjustable worktable that includes two individually raisable and lowerable work surfaces where the angular position of each work surface can also be adjusted individually. It is also disclosed in this patent specification that a convenient field of use is computer usage, where one work surface is used to support a computer screen and one work surface is used to support a keyboard, etc.
- Available workstations for instance workstations operating in accordance with the principle described in the aforesaid patent specification, are generally equipped for motorised vertical height adjustment for limited adaptation of the position of the tabletop and image presentation screens in relation to different users.
- the invention eliminates the aforesaid drawbacks by minimising deviations in the distance of the user's eyes to the image presentation screen both horizontally and vertically in a transition between an upright sitting posture and a rearwardly inclined posture.
- the manoeuvring device also enables the tabletop to be angled in the horizontal plane to suit a standing working posture without altering the distance of the user's eyes from the presentation screen concerned.
- the invention relates to a supporting arrangement in an image screen working station, including co-ordinated multifunctional motorised or mechanical counterbalanced movement of the tabletop and the image presentation screen relative to the different sitting and standing working postures of the user.
- a station for image screen work including co-ordinated multifunctional motorised or mechanical counterbalanced movement for the user's work surface and image screen supporting device relative to the different sitting and standing working postures of the user is effective in optimising the eye distance and position of the user in relation to an image presentation screen.
- Several image presentation screens may be handled simultaneously.
- the relationship between the user's work surface and the image screen supporting arrangement can be controlled mechanically, wherein the design of the supporting device can be adapted to a desired change in the relative position between said surface and said supporting arrangement, for instance by providing the stand with a guide groove as in the case of the illustrated exemplifying embodiment.
- the relationship between the user's work surface and the image screen supporting arrangement may be controlled mechanically, wherein the design of said supporting arrangement can be adapted to a desired change in position between said surface and said supporting arrangement, either by replacing appropriate parts of the arrangement or by providing said arrangement with adjustable functions.
- the invention also provides a limitation and adaptation of said multifunctional movement in respect of a standing working posture. Also provided is automatic limitation of the co-ordinated multifunctional movement, whose limitation is activated by the vertical height movement above a maximum height in respect of a seated working posture, so as not to alter the distance between the user's eyes and the image screen when angling the work surface with the user in a standing posture.
- the multifunctional movement is co-ordinated with the movement of the inventive subject in a vertical direction, so as to maintain a constant distance between the shortest distance of the tabletop to the surface of the floor.
- a coordinated function is provided between the angling of the work surface in the horizontal plane, caused by said multifunctional movement, with the movement in said vertical direction, so as to maintain a constant distance between the shortest distance of the work surface to the surface of the floor.
- a horizontal tabletop which retains its position in the event of a change in the angle and height of the movable desk shelf and image screen shelf. Also included is a horizontal work surface that retains its position in the event of a change to the angle and height of the movable table surface and to the arrangement for supporting the image screen unit.
- Figure 1 illustrates an embodiment of the invention intended for an upright sitting posture, and shows units and distances of significance
- Figure 2 illustrates the embodiment in an angularly changed position for a rearwardly inclined seating posture
- Figure 3 illustrates an embodiment in a position for a standing working posture
- Figure 4 illustrates an embodiment in an angularly changed position for a standing working posture
- Figure 5 illustrates the function of the guide groove in respect to the relative movement of the tabletop and the image presentation screen, where reference 5a indicates an unchanged position between work surface and screen and where reference 5b indicates a first angularly changed position, while reference 5c indicates a second angularly changed position.
- the illustrations 4-7 in Figure 5d show four possible designs of the guide groove for four different patterns of movement between the angular positions of the tabletop and the screen.
- the exemplifying embodiments of the invention illustrated in Figure 1 include a presentation device in the form of a display screen 2 in connection with a work surface in the form of a tabletop 3.
- the screen is releasably mounted on a supportive device in the form of a screen plate 4. All of these units can be displaced vertically at one and the same time, by virtue of being fixedly mounted on a stand 5 which, in turn, is mounted on a vertically extendable leg arrangement 13, for instance a telescopic arrangement.
- the stand 5 is provided with a guide groove 7 into which a stand bearing S is intended to be displaced by one end of a manoeuvring device 6.
- the manoeuvring device 6 may have the form of a pneumatic spring or of a motorised setting device whose other end is mounted on the stand 5, either directly or indirectly.
- the bearing is placed on the uppermost part 13A of the leg arrangement 13.
- the tabletop 3 is fastened to an angle-adjustable or pivotal frame 8 which is mounted in the stand 5 in a frame bearing 8A.
- One end of a forwardly located link arm 9 is mounted on the pivotal frame 8, while the other end of said arm is mounted on an attachment arm 11 on which the screen plate 4 is firmly mounted.
- One end of a rearwardly located link arm 10 is mounted on a displaceable frame bearing S while the other end of said arm 10 is also mounted on the attachment arm 11.
- This construction of a link mechanism 6, 7, 8, 9, 10, 11 enables the movements and degrees of freedom of the screen and the tabletop to be varied to an extent greater than the actual need, by appropriate dimensioning of the units consisting of the manoeuvring device 6, the guide groove 7, the pivotal frame 8, the forwardly located link arm 9, the rearwardly located link arm 10 and the distance between the bearings in the attachment frame 11 , with respect to size and placement.
- the guide groove 7 is provided on the fixed stand 5, which is not angled.
- the manoeuvring device 6 and the rearwardly located link arm 10 are fastened in the guide groove 7.
- the pivotal frame 8 constitutes a fourth link between a rearwardly located link bearing 81 and a forwardly located link bearing 82. This results in a four-link mechanism, which is adapted for movement by the manoeuvring device 6, while the mechanism as a whole - which is supported by the fourth link - is also pivotal about the frame bearing 8A.
- Figure 2 shows a changed angular position, corresponding to a rearwardly inclined working posture.
- the forwardly located link arm 9 and the rearwardly located link arm 10 form a flexible parallelogram such that the forward link arm 9 will be controlled by the rearward link arm 10.
- the region in which the manoeuvring device 6 moves and its length of stroke, coupled with the length and design of the guide groove 7 and the lengths 9L and 10L of respective link arms and their mutual length relationships control the co-ordinated movement regions of the tabletop 3 and the image screen 2.
- the geometries have been changed by reducing the height of the user's eyes 1 to aY2, which corresponds to cY1 , and the front edge of the table surface has been lowered to bY2.
- Figure 3 illustrates the arrangement adapted for an upstanding working posture, where the geometries in respect of the perpendicular screen distance aX1 and the horizontal screen distance bX1 are the same as those shown in Figure 1 , although the distance of the horizontal table surface bY3, and the screen height cY3 and the height of the user's eyes aY3 from the surface of the floor have, of course, been increased.
- an increase in the angle of the tabletop 3 and the screen plate 4 of equal magnitude is particularly beneficial, or indeed necessary, in the case of a standing working posture, where the user's eyes 1 relative to the screen 2 in the case of a desk-like angling of the tabletop 3 does not change as when a transition is made between an upright sitting posture and a rearwardly inclined posture. It is therefore appropriate to restrict angling of the tabletop 3 to the synchronised region of the screen plate 4 above the maximum height of said tabletop 3 intended for a seated working posture. This limitation may, for instance, be activated by the unit responsible for the vertical height movement 13 in the transition between a seated and a standing working posture.
- the pattern of movement of the tabletop 3 and the image screen 2 can be varied without practical limitations to construction and measurement geometry, by giving the guide groove 7 the shape and size illustrated in Figures 5d4, 5d5, 5d6 and 5d7.
- this flexibility can be utilised by replacing the stand 5, or parts thereof, with another desirable guide groove, or by enabling the shape and length of the guide groove to be adjusted (not shown).
- the design of the guide groove shown in Figure 5d4 is identical with the design of the guide groove shown in Figures 5a, 5b and 5c.
- the synchronised angling of the tabletop and the image screen can be increased by increasing the inclined radius-forming part of the guide groove in accordance with Figure 5d5.
- the design of the guide groove 7 according to Figure 5d6 i.e. in the absence of radius-controlled movement and synchronisation, provides a comparatively slow increase in the angling of the image screen in relation to the tabletop, while the design according to Figure 5d7 provides a faster increase in the angular difference.
- the distance between the front part of the tabletop and the surface of the floor 12 can be kept constant, by synchronising vertical movement away from the floor surface 12 with the unit responsible for said vertical height movement 13A, in parallel with angling of the tabletop 3.
- the angle defined by the tabletop 3 with the screen plate 4 can be increased, e.g. synchronised, by forming the guide groove 7 as a radius with its origin of co-ordinates in the rotational centre 8A of the pivotal frame 8, see Figure 5d5.
- This part of the guide groove may otherwise be straight, see Figure 5d4, instead of being radius-forming, depending on the mutual measurement conditions.
