Figure 18 is a view in. plan of the blank from which is produced the article as illustrated in Figures 16 and 1'7. I
Figures 1 and 2 illustrate an embodiment of my invention wherein the article of furniture constitutes a chair. This article or chair is produced from a rectangular blank B of required di- 'mensions and which is provided along its opposite side marginal portions at desired points spaced inwardly from the side edges thereof with the slits l and 2 open at the ends ofthe blank B. These slits terminate in close proximity to the longitudinal center of the blank B with the slits I closer to said longitudinal center than the go inner ends of the slits 2.
' The slits I are of the same length as are also the slits 2 and the portion 3 of the blank be tween the'slits 2 is flexed across a transverse I line, as at 4, at a point closely adjacent to the as inner ends of the slits 2 to provide an upstanding back for the chair, said back being disposed on such angle with respect to the horizontal as may be preferred.
The side portions of the blank B outwardly of theslits 2 are transversely flexed adjacent the inner ends of the slits 2 to provide the downwardly disposed rear supporting legs 5. The side marginal portions of the blank B outwardly of the slits I are transversely flexed immediately adjacent to the inner ends of the slits I to provide the downwardly and forwardly inclined front supporting legs 6 and the forward extremity of the portion of the blank between the slits I is downwardly curved, as at I, with said curved 40 portion continued by an inwardly and downwardly inclined apron 8 extending between \the legs 8 with the outer or free extremity 9 of the apron 8 outwardly and downwardly flexed to be substantially coplanar with the legs 6. The ends 5 of this extremity or strip 8, in the present embodiment of the invention, are each welded, as at III, or otherwise rigidly secured to the adjacent leg 8.
As illustrated by Figures 1 and 2, the chair is of 0 a type to allow for comfortable lounging although trated in Figures 4, 5 and 6, the article of furniture constitutes a stool and is produced from a rectangular blank E of desired dimensions provided along its side-marginal portions at desired.
points spaced inwardly of the longitudinal edges of the blank R with the slits ll open at the ends of the blank R. In this embodiment of the invention, the slits ii at each end of the blank R are of the same length and are in parallelism with one another and the slits ii at one end are also of the same length, as the slits at the opposite end of the blank. The slits II, as clearly illustrated in Figure 6, terminate at points closely adjacent to the longitudinal center of the blank R.
The portions of the blank R outwardly of the slits ii are transversely flexed closely adjacent their inner ends to provide the downwardly diverging supporting legs I! while the outer end portions of the blank between the slits ii are downwardly reverted, as at I4, and terminate in the extremities or cross members [6 fltting between and coplanar with the legs 12 and welded or otherwise rigidly secured thereto, as at l6.
Figures 7 and 8 illustrate a desk or the like constructed in accordance with the present invention and such article is produced from the blank A, as illustrated in Figure 9. This blank A is herein disclosed as rectangular in form and of required dimensions and is provided along its opposite sides and closely adjacent to its longitudinal edges with the slits I! and ill. The slits I! at the front end of the blank are in parallelism and of the same length and terminate in relatively close proximity to the longitudinal center of the blank A and the slits i8 are also in parallelism and are herein disclosed as slightly longer than the slits II. The portion is of the blank A is upwardly flexed transversely of the blank along a transverse line 26 closely adjacent to the inner ends of the slits II to provide a substantially vertically disposed back, with the upper or free extremity of this portion or back I9 forwardlyflexed along the line 2| to provide a forwardly directed shelf 22 substantially at right angles to the portion or back l6.
The inner portion ll of the blank A is provided with a U-shaped slit 28 with the base member thereof closely adjacent to the line 20 of flexure. The part of the portion or back l6 defined by this slit 23 is bent or folded along a transverse line 24 immediately adjacent to the free extremities of the side portions of the slits 23 to provide a forwardly directed second or lower shelf 25 also substantially at right angles to the portion Or back IS. The forward or free longitudinal marginal portion of the shelf 26, as herein disclosed, is flexed to provide therealong an upstanding retaining ledge 26.
The portions of the blank A outwardly of the slits i8 closely adjacent to the inner ends of said slits i8 are transversely flexed to provide the downwardly and forwardly inclined front supporting legs 21 while the portions of the blank outwardly of. the slits l! are transversely flexed adjacent to the inner ends of said slits II to provide the depending rear supporting legs 26.
The outer or forward extremity of the portions 29 of the blank A between the slits l6 at a desired point intermediate the ends thereof is downwardly and rearwardly curved, as at 30, and continued by a downwardly and rearwardly inclined apron 3i having its outer or free extremity formed to provide a transverse strip 32 snugly fltting between the front legs 21 and welded, as at 33, or otherwise rigidly secured thereto.
In Figures and 11 is illustrated an armchair constructed in accordance with an embodi ment of the present invention and such chair is produced from the blank C illustrated in Figure 12. This blank C is rectangular in form and of desired dimensions and is provided in its side marginal portions with the slits 34 a desired distance inwardly of the longitudinal edges of the blank C. These slits 34 are parallel and extend from a point in close proximity to one end of the blank C to a point in close proximity to the opposite end of the blank;' However, such last-named extremities of the slits are spaced from the adjacent end of the blank C a distance greater than the space between the opposite ends of the slits 34 and the adjacent end of the blank C. I
The part of the blank 0 between the slits 34 and at a desired point inwardly of the ends of the slits 34 spaced the greater distance from the adjacent end of the blank 0 is transversely flexed along the line 36 to provide an upstanding back 36 and along a second transversely disposed line 31 this part of the blank is downwardly curved, as at 38, to provide a seat 66 while the downwardly curved portion 38 is continued by a downwardly and rearwardly disposed apron 40 terminating at the adjacent ends of the slits J4,
the transverse portion or strip 4| of the blank C outwardly of said ends of the slits 34 being disposed for flat contact with the supporting surface or in a position substantially parallel with the seat 39, although this parallel relation is not essential.
The portions of the blank C outwardly of the slits 34 are transversely flexed, as at 42, at desired points spaced lengthwise thereof to provide the substantially U-shaped side elements, each substantially U-shaped in form with the intermediate portions 43 thereof disposed closely adjacent to the forward end of the seat 39 and substantially vertically disposed. The side members 44 and 46 of each'of the elements 43 are substantially horizontally disposed and are, of-
' ment of my invention which constitutes a book rack and this article is produced from the blank D. This blank D is of desired dimensions and is rectangular in form with its length in the present embodiment considerably less than its width although this is not of any particular-import. The blank D adjacent to one end is provided thereacross with a slit 46 extending substantially entirely across the blank D but closed at its opposite ends. The extremities of this slit 46 open into the perpendicularly related slits 41 extending equidistantly beyond opposite sidesof the slit 46. In the present embodiment of the invention, the slit 46 together with the slits 41 are to substantially one side of the longitudinal center of the blank D although this may be otherwise changed.
The blank D along the transverse line 46 immediately adjacent to the inner end of the slits 41 isflexed to provide a supporting plate or foot 46 to rest upon a table top or other support while the portion of the blank D provided with the slits 46 and 41 constitutes a plate 60 which is disposed upwardly and rearwardly with respect to the supporting plate or foot 46 on an angle of approximately 45 degrees, with the merging marginal portions of the plates 48 and 58 outwardly rounded, as at The portions of the plate 58 above and below the slit 48 and between the slits 41' are inwardly flexed along the transverse lines 52 between the extremities of the slits 41 to provide the substantially perpendicularly related plates 53 and 58, the plate 53 constituting the back for the rack.
Figures 16 and 17 illustrate an articleof furniture which constitutes a table or kindred article and which is produced from the blank E, as illustrated by Figure 18. In this embodiment of the invention, the blank E is rectangular in form and of desired dimensions and is provided in each end portion with the parallel slits 55. In the present embodiment of the invention the slits 55 at one end of the blank E are substantially of the same length ,as the slits 55 at the opposite end and these slitsr55 at both ends of the blank E extend only a comparatively short distance inwardly of the'ends of the blank E. v
The blank E inwardly of and closely adjacent to the inner ends of the slits 55 is provided with the U-shaped slits 58, with the side portions of the slits inwardly disposed. These slits 58 are substantially in duplicate and are equi-distantly spaced at opposite sides of the longitudinal center of the blank E. i
The blank E along the transverse lines 51 are folded to provide a central table top 58 while the portions of the blank E between the side lengths V of the slitsj58 and along the transverse lines 58 at the inner ends of said side portions of the slits 58 are folded to provide the table extenof which sions 80, the outer marginal portions are upwardly flexed, as at 8|.
The portions of the blank E between the slits 55 and along the transverse lines 82 at the inner maybe used for the purpose of display or otherwise, as may be desired.
While it has been hereinbefore stated that in the several embodiments of the invention the different articles are to be made from a single blank or sheet of material, it is believed to be obvious that similar structures may be obtained by molding.
- From the foregoing description it is thought to be obvious that an article of furniture constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and used.
