Definitions

  • This invention relates to improved seating.
  • the present invention aims to alleviate the abovementioned disadvantages and to provide improved seating which will be reliable and efficient in use. Other objects and advantages of this invention will hereinafter become apparent.
  • this invention in one aspect resides broadly in seating including:- a supporting base; a seat member on said supporting base for supporting the posterior of a user, and mounting means for connecting said seat member to said supporting base whereby the latter is pivotable about a transverse horizontal axis between opposite sides of a normal seating position.
  • the seat member and knee pad are freely pivotable so that in use they automatically adopt the inclination set by the user. It is also preferred that the seat and/or knee pad be resiliently biassed to a set inclination from which the seat and/or knee pad may be pivoted and for this purpose there is provided biassing means for biassing said seat member to said normal seating posi tion .
  • the biassing means is associated with the mounting means, but of course it could be independent thereof.
  • the biassing means could be resilient buffers supported on the supporting base and arranged to engage the underside of the seat member. It is also preferred that the resistance to pivoting afforded by the biassing means increases as the seat member pivots away from the normal seating position.
  • the seating of this invention can be utilized in various types of seats, stools and chairs and the like and in another aspect this invention resides broadly in seating of the type defined above and having a seat member which is inclined in the normal seating position and an associated knee pad supported by said base member whereby the knee pad is pivotable about a transverse horizontal axis between opposite sides of a normal supporting position.
  • FIG. 1 is a perspective view of a chair for use in a sitting/kneeling position
  • FIG. 2 is a side view of the chair illustrated in FIG. 1;
  • FIG. 3 is a cutaway perspective view of a preferred form of mounting for connecting the seat/knee pad to the base f ame;
  • FIG. 4 is a perspective view of a further embodiment of the invention.
  • FIG. 5 is a side view of a modified form of the chair illustrated in FIG. 4, and
  • FIGS. 6 and 7 illustrate further embodiments of the invention.
  • the chair 10 has a conventional spider base assembly 11 mounted on castors 12 and having a height adjustable swivelling mounting post 13 which supports the main frame 14 of the supporting assembly 15.
  • the latter includes a seat member 16 which is normally inclined to the horizontal and a knee or shin pad 17 which is inclined in the opposite direction as illustrated.
  • the main frame 14 is rigidly secured to the mounting post 13 and in this embodiment it is in the form of a hollow- square section tube 9 which extends to opposite sides of the mounting post 13.
  • the upper portion of the tube 9 telescopically receives a smaller square sectioned tube 8 which supports a mounting assembly 19 for the seat member 16 whereby the distance between the seat portion 16 and the kne pad 17 may be selectively varied.
  • a locking bolt 20 is provided in the main frame 14 to hold the tube 8 in its selected telescopically adjusted position.
  • the mounting assembly 19 for the seat member 16 is similar to the mounting assembly 21 for the knee pad 17. As shown i FIG. 3, the mounting assembly 19 includes an outer transversely extending square tube 22 fixed to the end of the inner tube 8 and being provided with four rod like rubber buffers 23 fitted into the respective internal corners of the tube 22 so as to bear against a respective outer face of an inner smaller square section tube 24. The latter may rotate about its longitudinal axis within the outer tube 22 and it is supported between the angle brackets 25 adapted to be secured to the underside of the seat member 16 or the knee pad as appropriate.
  • the inner tube 24 is resiliently biassed by the buffers 23 to a normal or central position whereby the seat 16 is inclined downwardly towards the knee pad 17 as illustrated.
  • the seat member 16 may be pivoted about the axis of the inner tube 22 in either direction by compressing the four rod like rubber buffers 23 between the inner and outer tubes 24 and 22 respectively.
  • the seat member 16 may be pivoted to a substantially horizontal position so that it can be used as a conventional stool.
  • the seat member 16 will return to the inclined position illustrated when not in use and when in use the seat will pivot freely to a supporting position determined by the users size and physique.
  • the knee pad 17 is supported in the same manner as the seat and thus it may be pivoted about the axis of its inner tube 26 so that in use when a user supports himself upon the seat 16 and the knee pad 17, the latter will automatically pivot to the angle set by the users .
  • the mounting shaft 13 is of the type which is biassed to and normally held in an elevated position, but which may be lowered to a selected position upon actuation of the lever 27. This may be arranged so that it can be actuated by the heel of a seated user.
  • the chair 10 is also provided with height adjustable armrests 26 which are supported from the angle brackets 25. The armrests may be removed if desired.
  • the mounting assembly 19 may be provided with a stop bar 29 extending between the angle plates 25 and arranged to abut the outer face of the tube 22 so as to limit pivotal movement of the brackets. This arrangement may be used to prevent the seat from pivoting beyond a- horizontal position. Furthermore, the main frame member 14 may be cranked so as to extend downwardly to one side of the kneepad 17 to provide easier access thereto.
  • the chair 30 illustrated in FIG. 4 has a seat 16a and knee pad 17a which are supported in a similar manner to the seat and kneepad described above. However each is supported by a respective strut 31 and 32 extending upwardly from opposite ends of a base frame assembly 33.
  • the struts 31 and 32 are length adjustable, as is the central spine 34 of the base frame assembly 33 so that the distance between the seat 16a and the kneepad 17a may be selectively varied.
  • the latter are resiliently mounted as per the previous embodiment.
  • the seat 16a can be used individually and in conjunction with the flexibly mounted kneepad 17a or the seat 16a and kneepad 17a may be interchanged as shown in , dotted outline whereby a person may use the then elevated kneepad as a backrest.
  • the outer edge of the backrest is cutaway as shown at 35 to provide adequate lumbar support when used for that purpose.
  • FIG. 5 illustrates a chair 40 in which the seat member 41 is normally supported horizontally but which may pivot to either side to suit a user.
  • the backrest 42 is similarly supported by a mounting assembly of the type illustrated in FIG 4 whereby it may pivot resiliently to either side of a central position.
  • This chair is also provided with armrests 45.
  • the backrest has a telescopic support frame whereby it may be adjusted for height and lateral spacing from the seat 41.
  • the stool 50 illustrated in FIG 6 is similar to the chair of FIG. 5. However it has a taller base frame assembly 51 and a stop bar of the type shown at 29 in FIG. 3 to limit its pivotal movement in one direction to a substantially horizontal position.

Abstract

La chaise décrite (30) comprend un siège (16a) et un appui-genoux (17a) montés de façon flexible, chacun des éléments pouvant pivoter indépendamment autour d'un axe horizontal respectif. Le siège (16a) et l'appui-genoux (17a) sont inclinés de façon flexible dans une position centrale, chacun pouvant pivoter pour occuper des positions de support inclinées du côté opposé à leur position centrale. Le siège (16a) et l'appui-genoux (17a) peuvent ainsi automatiquement pivoter pour occuper la position de support qui convient à l'utilisateur.
