Definitions

  • the invention concerns a built-in footrest mechanism in combination with a chair, said mechanism comprising a support which can be moved between a folded-in position in which it is situated under the seat and a position in which it is situated in front of the seat; a frame which is mounted under the seat in the chair; an auxiliary frame which is telescopic in relation to said frame and upon which the support is movably mounted; and a common drive for sliding the above-mentioned auxiliary frame in and out and for moving the support in relation to this auxiliary frame.
  • Such a footrest mechanism makes it possible to bring the support, upon which is provided a cushion or such, in front of the seat, so that a person resting in the chair can put his feet on this cushion.
  • the support is a part of the front of the chair situated under the seat which can be folded out forward, for example by means of a shear mechanism.
  • a footrest mechanism of this kind is for example disclosed in US-A-3.794.381.
  • the support is pivotaly connected to the front and the drive can pivot the support from its vertical position in the front of the chair to a horizontal position just in front of the seat.
  • the support in folded-out position, is situated practically against the seat, which in many cases is not an ideal position to support the feet.
  • the calves rather than the feet rest on the support, which is for example undesirable for people suffering from varicose veins.
  • the invention aims to provide a built-in footrest mechanism in a chair which fits in several chairs and which can bring the support in the suitable place in relation to the seat and yet has quite a simple construction.
  • this aim is reached because the support is connected to the telescopic auxiliary frame by the intermediary of a tilting connection containing on each side a pair of arms whose ends are connected in a hinged manner to the auxiliary frame and in a hinged manner to the support, whereby the drive is connected to the tilting connection
  • EP-A-0.534.908 discloses a footrest mechanism comprising a support connected by the intermediary of two pair of arms to a telescopic auxiliary frame mounted on a fixed frame.
  • this mechanism does not comprise any drive and as well the telescoping of the auxiliary frame as the tilting of the support are manually.
  • the footrest mechanism according to the invention contains means which, when the drive extends this auxiliary frame, hold the support in its lowest position on this auxiliary frame until this auxiliary frame is almost completely extended.
  • These means may consist of clamping means, in particular of at least a spring.
  • the invention also concerns the footrest mechanism as such which is fit to be built-in in a chair.
  • Figure 1 schematically represents a chair 1 which mainly consists of an underside 2 carrying a seat 3, a back 4 and two armrests 5.
  • a footrest mechanism is built-in in the underside 2 which mainly consists of a frame 6 which is fixed in the underside 2, an auxiliary frame 7 which is telescopic in relation to said frame 6, a support 8 which is mounted adjustable in height on the auxiliary frame 7 and a common drive 9 to slide the auxiliary frame 7 in and out and to move the support 8 up and down in relation to the auxiliary frame.
  • the auxiliary frame 7 can be slid in and out in relation to the frame 6 by means of two horizontal telescopic arms 10 which each consist of two rails 11 and 12 which can slide into one and other with a C-shaped section and a profile 13 with an L-shaped section which can slide in the rails 11 and 12.
  • the rails 11 are fixed to or are part of the frame 6 which is connected to the underside 2 of the chair 1 as represented in figure 7.
  • the L-shaped profiles 13 are fixed to or are part of the auxiliary frame 7 and they are connected to one another with their ends by means of a cross piece 14.
  • the distance between the telescopic arms 10 can, as represented in the figures, be smaller than the width of the underside 2, in which case these arms 10 are fixed by the frame 6 to this underside 2.
  • the support 8 is mounted adjustable in height on the cross piece 14 by means of a tilting connection 15 which mainly consists of two pair of arms 16-17 on either side of the footrest mechanism.
  • the arms 16 and 17 of each pair are two laths which, together with two L-shaped profiles 18 and 19 form a deformable polygon which hinges in its corners.
  • the ends of these arms 16 and 17 are connected in a hinged manner by horizontal hinge pens 20 which are directed in the cross direction in relation to the telescopic arms 10, to the L-shaped profile 18 on the one hand and to the L-shaped profile 19 on the other hand.
  • the profiles 18 and 19 which are parallel to the telescopic arms 10 are directed such than hinge pens 20 belonging to a profile 18 or 19 are situated one after the other at the same height in the longitudinal direction of the arms 10.
  • the L-shaped profile 18 is fixed to the cross piece 14 whereas the other L-shaped profile 19 is fixed to the underside of the support 6.
  • the drive 9 consists of an electric jack which is fixed to the frame 6 under the telescopic arms 10 by means of a hinge pen 21 and an L-shaped profile 22 on the one hand, and which is hinge-mounted to the arms 16 of the two pairs 16-17 of the tilting connection 15 by means of a fork 23 and a shaft 24 sticking through it whose ends are borne in L-shaped pieces 25 which are fixed to the arms 16 on the other hand.
  • the shaft 24 is situated somewhat higher than the lowest hinge pens 20 with which the arms 16 hinge in relation to the cross piece 14, so that the arms 16 can be tilted by sliding the drive 9 in or out.
  • the support 6 mainly consists of a cross plate 26 which is carried by the two L-shaped profiles 19 and a forwardly directed arm 27 which is fixed to the cross plate 26 and is situated almost in line with the L-shaped profile 19 on one side.
  • clamping means which consist of a spring 28 which is fixed to this arm 27 on the one hand and to a protrusion of the arm 16 of one of the pairs 16-17 of the tilting connection 15 on the other hand.
  • This spring 28 is a draw spring which draws the arm 27 towards the arm 16, as a result of which the tilting connection 15 tends to tilt downward. Consequently, the spring 28 forms means which try to bring the support 6 into a bottommost position and oppose the tilting upward of the tilting connection 15.
  • the tractive effort can be adjusted by removing the fastening point of the spring 28 to the arm 27.
  • This arm 27 is provided to this end with a number of openings in which an end of the spring 28 can catch.
  • a cushion 29 can be fixed on the support 8.
  • the drive 9 formed by the electric jack can be protected by a U-shaped cap 30.
  • the footrest mechanism In folded-in position, the footrest mechanism is in the position as represented in the figures 1, 6 and 7, whereby the telescopic arms 10 are slid in and the support 8 is situated in its lowest position on these telescopic arms 10. The entire footrest mechanism is then situated in the underside 2 of the chair 1 under the seat 3.
  • the drive 9 is activated. Although this drive 9 acts on the arms 16 of the tilting connection 15 through the medium of the shaft 24, these arms 16 will not be tilted immediately due to the presence of the spring 28.
  • the support 8 remains in its lowest position and only the telescopic arms 10 are extended first.
  • the spring 28 forms means which not only try to move the support 8 downward, but which also prevent the support 8 from being moved upward by the drive 9 as long as the auxiliary frame 7 is not fully extended and the support 8 is not situated in front of the underside 2.
  • the upward tilting of the tilting connection 15 is restricted thanks to the maximum extension of the jack which forms the drive 9.
  • This connection 15 is represented in figures 3 and 5 in its maximally tilted position.
  • the support 8 In this position, the support 8 is in its highest position, in front of the seat 3, almost in line with this seat.
  • the jack which forms the drive 9 is slid in again. Due to the spring 28, the support 8 will hereby be brought down first, after which the auxiliary frame 7 is slid in due to the sliding in of the telescopic arms 10.
  • the design of the above-described footrest mechanism is quite simple.
  • the support 8 and thus also the cushion 29 mounted upon it cannot only be put in the required height, but also at the required distance in front of the seat 3.
  • the footrest mechanism is relatively compact and can be built-in in different chair models.
  • the total width of this footrest mechanism without the frame 6 is smaller than the width of the underside 2 of a normal chair.
  • By means of an adjusted frame 6 it can be fixed to the broader underside.
  • the auxiliary frame 7 must not necessarily have a cross piece 14.
  • the two pair of arms 16 and 17 of the tilting connection 15 can be fixed directly to the telescopic arms 10, so that the auxiliary frame 7 can be practically restricted to the telescopic profiles 13 of these arms 10.
