Definitions

  • This invention generally relates to easy chairs or like articles of furniture and, more particularly, to -a new and improved easy chair of collapsible type to facilitate the transportation thereof and including an essentially rigid framing having a Ifront side portion, a rear side portion and symmetrically located lateral side portions, leg forming members hingedly secured to said framing to form therewith a collapsible framework, and a large strip of flexible textile material longitudinally arranged in said framing and having its rear and front end portions secured to said rear and respectively front side portion of said framing to form the seat and back-rest component of the chair.
  • Such collapsible easy chairs are widely known and appreciated in particular for garden, beach, camping and in general for outdoors use. Taking into account their structural simplicity, light weight and easy transportation, such easy chairs are considered as satisfying comfortable, even if the fabric seat component is generally considered somewhat rigid.
  • Such chairs are mostly provided with an ⁇ adjustable framework for adjusting the inclination of their seat forming fabric strip, and with strings for adjusting the deepness of the downward bow formed by said fabric component as loaded Iby the users body weight.
  • Such provisions lead however to an undesired structural complexity and the adjustable chairs of the type heretofore known require action and operations for their adjustment to a more or less reclined position as desired for example for reading :and conversation and respectively for rest and relaxing.
  • Another object of this invention is to provide an improved easy chair as above, which is distinguished by the provision of a transverse resiliently extensible support member secured at its opposite end portions to the said symmetrical lateral side portions of said framing, said .transverse member being slidably displaceable along said lateral portions for adjusting the bow of said seat Iforming structure as loaded by the users body.
  • a further object of this invention is to provide an improved easy chair as above, distinguished bythe provision of a framing having an essentially trapezoidal configuration having its greater and smaller base at said front and respectively at said rear side portion thereof, whereby, the farther said transverse support is displaced towards said -fore or front portion, the more its elongation and stretching are increased to provide a correspondingly increased supporting force.
  • a still further object of this invention is to providev an easy chair as above, distinguished by the extreme simplicity of its framework and by the easiness of the operations required for collapsing said framework for storage and transportation and, respectively, for setting the chair up again for comfortable use thereof.
  • FIGURE l is a perspective View showing the chair in its normal position of use
  • FIGURE 2 is a like view showing same chair in its fully collapsed position of transportation
  • FIGURES 3A aud 3B are .somewhat diagrammatical showings of the chair, in longitudinal vertical sectional view, directed to illustrate the different arrangement and bow of its seat and back-rest forming component under two different positions of the users body;
  • FIGURES 4 and 5 are fragmentary perspective views of details of the hinge connections of the various oomponents with the framework.
  • FIGURE 6 is a perspective view similar to FIG. 1 and showin-g a modified embodiment of the improved chair.
  • FIGS. 1 and 2 there is sho-wn a collapsible easy chair having a rigid framing generally indicated at 10 and of essentially trapezoidal configuration.
  • Such framing may be preferably constructed of tubular metallic material yand comprises a rear side portion 11, a fore side portion 12 parallel to said rear side portion, and symmetrically located lateral side portions 13 and 14.
  • leg forming components hingedly connected to said rear and fore side portions, preferably by means adapted to secure said components at the required inclination thereof.
  • said leg forming components may include a downwardly directed rear supporting structure 15 having two symmetrically diverging members and a reinforcing cross member secured therebetween, as shown, and two diverging and downwardly slanting fore legs 16.
  • Such components are preferably made of metallic tubular materal also. The manufacture of the above frame structure of tubular material appertains to common knowledge of those skilled in the .art and therefore no further detail will be herein set forth thereabout.
  • the users body seat and back-rest forming structure is suitably secured to and stretched between said rear and fore side portions of said framing 10.
  • Said structure includes a rear upper back-rest portion 17 and as a seat -a lower fore portion 16, said portions being critically formed by a flexible and resiliently extensible material, su-ch as by a plurality of parallel and spaced elastic strips 19 made of a material including rubber warp threads or otherwise elasticized fabric, and respectively by a flexible but not extensible material, such as -a fabric of the type conventionally made use of for providing the seat and/or back-rest surfaces of garden chairs, lounges and other collapsible or f-oldable articles of the character considered.
  • Said rear upper portion and said fore lower portions 17 and 18 are rmly secured to each other at transverse alignment indicated at 21, by means of sewing, riveting or other conventional means.
  • the said rear portion 17 is shorter than said fore portion 18.
  • the ratio of the length of said rear extensible portion (as fully stretched) to the length of said not extensible fore portion, in the space defined between said rear and fore side portions of the framing, such space being preferably on the order of 3 feet or slightly more, is comprised between a ratio of 1 to 3 and 1 to 4.
  • the length and the slant of the supporting structure formed by said components and 16 is such as to support the said framing 10 at a suitable inclination to horizontal.
  • Such inclination may be advantageously defined by an angle A (FIGS. 1, 3A and 3B) comprises between 20 and 30 degrees, and preferably of 25 degrees; however, provision may be made for adjustment at will of such inclination, as discussed below with reference to FIG. 6.
  • the improved easy chair of this invention can advantageously be provided also with a further body supporting component consisting of a transverse resiliently extensible member 22, preferably made of elasticized strip material and arranged between said lateral side portions 13 and 14.
  • a transverse resiliently extensible member 22 is arranged to pass beneath the longitudinal compound made support structure 17 and 18 and is slidable along said lateral side portions 13 and 14, so that it may be arranged at different positions in the interval defined between said rear and fore side portions 151 and respectively 12.
  • FIGS. 3A and 3B there are shown two different positions i-n which said transverse extensible strip may be arranged, for example.
  • lSuch transverse strip may be provided with a buckle or other conventional means for full removal and/or for Kadjustment of the stretching thereof, if desired.
  • FIGS. 3A and 3B The new and surprising advantages of the above described arrangement and combination of parts of the improved chair will be readily apparent from a comparison of the showings of FIGS. 3A and 3B.
  • the compound body supporting structure 17 and 18 will adapt itself to ⁇ a different configuration, bow and deepness. If the u'ser sits on portion 18 fairly far from side portion 12 of the framing, the rear upper extensible portion 17 of said structure will be more stretched and the entire structure will assume the most suitable con'- figuration (FIG. 3A) for sitting. On the other hand, if the user sits fairlynear to said fore side portion 12 and leans backward (FIG.
  • a pillow l23 (FIGS. 3B -and 6) 'may be provided and preferably connected by y strings to the said upper rear side porti-on 11 of the framing vfor providing a comfortable head-rest.
  • the arrangement of the said extensible pre-stretched transverse strip 22 may be adjusted for best adaptation of the chair to the desired -rest position.
  • FIG. 3B there is shown how the said transverse strip 22 may be adjusted in a position such as to provide a comfortable support for the users waist. It is evident that a means for .adjustment of the saidl components, such as of the stretching of ⁇ the extensible members and parts, may be provided for best adaptation of the improved chair to different users diverence, body weight and size.
  • FIGS. 4 and 75 5 illustrate a preferred but not critical construction of said means, wherein the rear supporting structure 15 may be latched to resist movements in any direction, while the fore legs 16 abut on stop means in their most downwardly and forwardly extended position.
  • the two parallel upper end portions 15' of lrear supporting structure 15 are secured, by welding for example, to short sleeves 40 rotatably arranged .about the said upper rear side portion 11 of framing, which therefore will embody the axis about which said structure may be swung for setting the chair up (FIG. 1) or collapsing it for facilitating its storage and transportation.
  • Said portions are provided with longitudinally extended slots 41 wherein and wherealong a flat rod 43 is arranged for guided displacement in the plane defined by said portions 15.
  • Such rod 42 is upwardly urged by spring means, such as coil springs 43 arranged within said portions 15', and it is provided with an eye such as shown at 44 so as to permit a user to exert manually a downward pull.
  • each sleeve 40 shaped fianges 44 are arranged and secured to said rear side portion 11, for example by welding.
  • Such ⁇ fianges define the position of said sleeves and therefore of the rear supporting swingable structure 15 along said rear side portion 11.
  • said flanges are downwardly elongated and provided with notches or ⁇ slits 45 wherein said rod 42 may fit when it is urged close to said upper side portion 11, as shown. Said rod 42 therefore acts as a latch for preventing the Irotation of said structure 15 about the axis of portion 11 and defining the operative position of said structure in the chair.
  • Said flanges 44 may be shaped to form a camming surface at their edges, wherealong said rod 42 ⁇ may slide and be thereby caused to retreat as the structure 1S is ⁇ being swung back in its operative position ⁇ and then snap into engagement in said notches 45 to facilitate the setting of the chair for use.
  • each leg 16 (only one of which is shown in FIG. 5) is secured to a sleeve 50, by welding for example, positioned between flanges 51 secured to said fore side portion 12 of framing and integrally formed with a bow-shaped part 52 bridging over and about said leg 16 when in its operative position, to limit the downward and forward swinging of said leg.
  • each leg 16 with respect to the fore side portion 12 of the framing may be arranged lat locations comprised in the Width of the fabric 20 secured to said portion 12.
  • Such fabric may be provided with a suitable opening such as at 53, reinforced such as at 54 for the desired arrangement.
  • Said fore legs 16 may be manually swung back at a folded position essentially co-planar to the framing 10 (FIG. 2). Therefore ythe improved chair of the present invention may be collapsed to a package of very small overall dimensions, namely into -a completely flattened structure for facilitating its storage and transportation.
