Description

ARRANGEMENT IN A CHAIR, ESPECIALLY A CHAIR COMPRISING A CALF SUPPORTING BOARD
The Scope of the Invention
The present invention relates to an arrangement in a chair, especially in an adjustable chair, comprising a seat and a backrest which can be moved interdependently in order to alter the angle between seat and backrest, relative to a stationary bottom frame, and also comprising a calf supporting board, arranged by means of a mechanism to be capable of taking up a folded position underneath the seat when the angle between seat and backrest warrants that the user is in a sitting position, and arranged to cause, when an increasing angle between backrest and seat warrants that the user is in a resting position, the calf supporting board to be moved outwards to a substantially horizontal position.
Prior Art
From NO patent application 95.2410 is known an arrangement in a chair where the angle between its seat and backrest is glidingly adjustable, there being at the front edge of the seat a linked telescopic support, inclining upwards from the bottom frame of the chair, consisting of an initial supporting part, permanently fixed to the bottom frame, and a second supporting part, gliding relative to the initial supporting part, and being linked to the front edge of the seat, while at the same time an attachment bracket is fixed to the front edge of the seat which extends downwards and backwards along the outside of the said support.
According to the Norwegian patent application there is also suggested an angle iron which is permanently fixed to the initial supporting part in order thereby to allow a gliding hook bar to slide along the angle iron or not to be in contact with the angle iron, depending on the position for use taken by the foot rest. Also from Norwegian patent application 93.0452 is known an arrangement in a chair where the angle between its seat and backrest is glidingly adjustable and in which the front edge of the seat is linked to a calf supporting board, it being at the front edge of the seat linked to a telescopic support from the bottom frame, inclining upwards from the bottom frame of the chair, being hinged at the front edge of the seat, and also a gas loaded spring connecting the foot rest and a fastening bar.
Known arrangements as stated build on the principle that a gas loaded spring will act when the angle between seat and backrest increases, so that the foot supporting board can be affected by the gas loaded spring in order to swing the board to a preferably horizontal position, while at the same time it must be possible to lock the board in the said position. The previously known arrangements, however, comprise a number of elements which entail that the arrangement cannot readily be adapted to existing chairs, which means that the arrangements will most commonly be used in connection with specially made chairs in which the design and adjustment devices as such are adapted to the various embodiments of the known arrangements.
The Aim of the Invention
The basis for the present invention is the task of providing an arrangement of the nature mentioned initially which can be readily and in a rational manner adapted to existing, adjustable chairs, in particular of the type
"Stressless" , or similar chairs, without the need to modify the overall design of the chairs.
Another aim of the present invention is to provide a description of a device which is constructed from fewer and simpler elements which entails rational production at a reasonable price, and also minimal storage space prior to sale and any mounting on chairs already finished. Yet another aim of the present invention is to provide a description of a device which may be mounted afterwards by means of simple tools.
Brief Summary of the Invention
These aims are achieved in a device of the kind stated initially being according to the invention characterised in that the calf supporting board with its pertaining mechanism is executed as a unit or a module which can be mounted on the underside of the seat of the chair and on the bottom frame as desired, especially on a finished chair of the "Stressless" type.
Appropriately a mechanism as stated may comprise a mounting bridle designed so that it is capable of being attached to the underside of the chair seat, and being at its forward area linked to a jib which carries the calf supporting board, the said jib being equipped with a small arm or executed with an arm portion for pivotal attachment of one end of a gas loaded spring, the other end of which is attached rotatably to a supporting arm extending from the said mounting bridle, and for pivotal attachment of a sliding rod being at its centre part executed with an inclined plane which continues in a hook portion and onwards in a double-curved end portion which is in turn arranged to interact glidingly with a stationary guiding armature which protrudes freely upwards from the bottom frame.
Appropriately, the freely upwards protruding guiding armature can then be attached to the bottom frame of the chair, and then without the need to make any additional preparations on finished chairs with appropriately adapted bottom frames.
Similarly, the said mechanism can, together with the calf supporting board, constitute a unit where the said unit may in a simple manner by means of the mounting bridle be attached to the underside of the movable seat, it all being adapted relative to the said guiding armature to achieve the intended automatic effect of the device, or the mechanism, respectively, when the chair is used.
Additional features and advantages of the present invention will be evident from the following description taken in conjunction with the attached figures of drawings, along with the attached patent claims.
Brief description of the Drawings
Figures 1 and 1A are a schematic sideways sketch of a chair comprising an embodiment for a device according to the invention, the chair being shown here in an initial position for use, namely a sitting position where the pertaining calf supporting board is shown in its folded position underneath the seat.
Figures 2 and 2A are a schematic sideways sketch similar to Figures 1 and 1A where the chair with its calf supporting board is shown in a second position for use, namely a position with an increased angle between backrest and seat, warranting a resting position for the user, where the calf supporting board has been swung out to a substantially horizontal position to take the weight off the user's legs.
Figure 3 is a perspective sketch showing a second embodiment of the device according to the invention, executed as a unit or a module which can easily be attached underneath the seat of an ordinary chair.
Figure 4 is a section of a perspective sketch showing the embodiment according to Figure 3 in the mounted and extended resting position.
Detailed description of Embodiments
Shown schematically in Figures 1 and 1A is a side-on sketch of a chair 1, e.g. an adjustable chair, comprising a seat 2 and a backrest 3 which can both be moved in order to alter the angle ocχ between the seat 2 and the backrest 3, and then relative to a bottom frame 4. Altering the angle oci may for instance be done by turning the backrest 3 backwards around a fixed pivot point, e.g. at the point C as shown in Figure 1 , which may be stationary relative to the bottom frame 4, while the chair 1 may be executed with a mechanism which will thereby allow movement of the seat 2 in a forward direction while at the same time the seat may rise somewhat in step with the increasing angle ocj..
Also shown in Figure 1 is a calf supporting board 5 which will be able to, by means of a mechanism which will be discussed further below, impact on the calf supporting board 5 to take up, on the one hand, a folded position, as shown in Figure 1, underneath the seat 2 when the angle oci between the seat 2 and the backrest 3 warrants a seated position of the user, and the said mechanism being arranged so that an increasing angle 0C2 , the way this is shown in
Figure 2, between the backrest 3 and the seat 2, warranting a resting position of the user, will cause the calf supporting board 5 to tip into a substantially horizontal position for use.
The calf supporting board 5 with its pertaining mechanism is according to the invention appropriately executed as a unit or a module, the way this will be discussed further in connection with the Figures 3 and 4, the said module being capable of being mounted on the underside of the chair seat 2 and on the bottom frame 4 according to wish, especially a finished chair produced of the type "Stressless" . This entails that a buyer may buy an ordinary adjustable chair without a footstool, and make his own choice whether he wants, when making his purchase, to have a calf supporting board mounted, or buy the calf supporting board at a later stage separately as a unit or module to be mounted afterwards by means of simple tools. The mechanism discussed so far comprises in an appropriate embodiment, as is evident schematically from the Figures 1 and 2, a mounting bridle 6 so arranged as to be capable of being mounted to the underside of the chair seat 2, and at its forward area 7 being executed with attachment members and in the same area having a linked connection 8 to a jib 9 which carries the said calf supporting board 5.
The jib 9 is equipped with or constitutes an arm portion 9a which provides a pivotal fastening of one end lla of a gas loaded spring or a gas cylinder 11 which has its other end lib rotatably fastened to a supporting arm 12 extending from the said mounting bridle 6. The said pivotal attachment 10 also provides a pivotal fastening for a sliding rod or a release arm 13 being at its centre area executed with an inclined surface 13a continuing into a hook area 13b and onwards into a curved end portion 14 which is in turn arranged to interact glidingly with a stationary guiding armature 15 freely protruding from the bottom frame 4.
In the position as shown in Figure 1, the curved end portion 14 of the sliding rod 13 will be in contact with the guiding armature 15 with a holding effect, i.e. the gas loaded spring 11 will, with the chair 1 in this position, not be affected, and the activating, stored force of the gas loaded spring 11 will not act upon the small arm or arm portion 9a, and thus not swing the calf supporting board 5 out from its folded position.
With an increasing angle 0(2 between the seat 2 of the chair and the back 3 of the chair, the way this is illustrated in Figures 2 and 2A, the sliding rod 13 will, together with the seat 2 and the mounting bridle 6 have its curved end portion 14 carried past the freely protruding, stationary guiding armature 15 which entails that the release arm 13 is lifted against an upper pivot clamp 16a to form a "pivot arm" together with the said pivot point . The gas loaded spring 11 will then be affected and with full force impact on the small arm portion 9a causing the calf supporting board 5 to swing out to the approximately horizontal position as shown in Figure 2, while at the same time the sliding rod or release arm 13 passes a holding clamp 16 fastened to the mounting bridle 6, in order thus to arrest the calf supporting board 5 from moving downwards after it has taken up its substantially horizontal position.
With a decreasing angle relative to the angle α2 as shown in Figure 2, the seat 2 with its attached mounting bridle 6 and the unfolded calf supporting board will be pushed backwards, entailing that the curved portion 14 of the sliding rod 13 will make contact with the upper portion of the guiding armature 15, thereby lifting the inclined surface 13a with the hook portion 13a out of the said holding clamp 16 whereby the user, by means of the weight of his or her legs, may move the calf supporting board 5 downwards towards its folded position as shown and discussed in connection with Figure 1.
In a per se known manner the calf supporting board 5 may be executed with telescopic elements allowing the length of the board to be adjusted, while at the same time the calf supporting board 5 may at its forward end be fitted with one or several wheels 17 which may make contact with the floor or the lower portion of the said guiding armature 15 for possibly shortening the length of the calf supporting board 5. This telescopic mechanism may be controlled by the force of gravity and allow the calf supporting board to be pushed out telescopically simultaneously with the calf supporting board being swung up.
In Figure 3 is shown in perspective a second embodiment of an arrangement according to the invention, where the calf supporting board 105, executed here as a cushion, with its pertaining mechanism, executed here as a unit or module, which may in a simple way be mounted on the underside of a chair seat, respectively on the bottom frame as desired, in particular on a finished chair produced of the type "Stressless" .
In Figure 3 the unit is shown in its folded position, corresponding to the sitting position of a chair as shown in Figure 1.
Shown in Figure 4 is in perspective a sketch of the way the unit shown in Figure 3 will look in its unfolded position or resting position, corresponding to the position which a chair may take up according to Figure 2.
Also in the embodiment as shown in Figures 3 and 4 the mechanism comprises a mounting bridle 106 arranged so that it can be fastened to the underside of a chair seat to follow the movements of the chair seat or the backrest and being at its forward end linked to a jib 109 which carries the actual calf supporting board or the calf supporting cushion 105.
The jib 109 is fitted with a small arm 109a for pivotal fastening of one end of a gas loaded spring ill having its other end lllb rotatably fastened to a supporting arm 112 protruding freely from the said mounting bridle 106. The jib 109 forms at its forward portion 109a also a pivotal suspension point for one end of a sliding rod or a release arm 113 being at its centre portion executed with an inclined surface 113a continuing in a hook portion 113b and onwards in a freely curved end portion 114, arranged to interact glidingly with the guiding armature 115 protruding freely upwards from the bottom frame 104 as shown in Figure 4.
In Figure 4 it is also shown that the bottom frame 104 may comprise a ring part of which is shown in the said figure, and that the guiding armature 115 may readily be mounted on this ring, i.e. without having to make any modifications on a finished produced chair with the pertaining bottom frame.
Also shown in Figure 4 is that the jib 109 may be executed telescopically so that the distance between the mounting bridle 106, respectively the pertaining seat of the chair, and the actual calf supporting board 105 may be adjusted according to wish.
