(Ci. 38-l17 12 Claims. 1

This invention'relates toan improvement in ironing boards, especially of the type adapted to fold together to a compact form.

An object of this invention is to provide an improved ironing board of simple and economical construction, having a foldable table and legs formed of articulated sections which can be folded within the table when the latter is folded together.

Another object is to provide foldable articulated supporting sections forv an ironing board of the aforesaid type wherein downward force on the table tends to hold the supporting sections in rigidly extended position.

Still another object of the invention is to pro- Vide an ironing board having cross oar reinforced, paired legs, and having automatic means for spreading said legs apart when they are being extended, thereby toincrease the stability of the board whilein use.

In accordance with my invention the foregoing objects are-accomplished by constructing an ironing board with a table having two hollow leaves of substantially equal length, which can be folded together at a transverse hinge; and supporting means comprising a plurality of articulated legs which can be folded and contained within the hollow portions of the leaves so to be enclosed thereby when the two leaves are folded together. One featureof the invention is the provision of foldable support means, comprising a plurality of articulated legs constructed. with knee joints i. e. hinges bendable in direction only to collapse the legs, and comprising foldable braces or struts for holding the legs in divergent position when extended for use, the lower portions of the legs folding inward or toward the vertical at the knee joints so that downward pressure transmitted from the table to the legs tends to hold the latter in rigidly extended position. Another feature of the invention is the provision of an extensible cross bar joining a pair of legs, and means carried by the cross bar for urging the same to extended position to spread the legs apart, thereby result ing in a compact and sturdy structure, and lend ing added stability to the ironing board when use. The cross bar is retractable to permit the legs to be moved inward so that'they can be folded within the cavity of a leaf of the table.

The foregoing and other objects and advantages of the invention will be understood more readily from the following description of a preferred embodiment of the invention taken in 2 connection with the accompanying drawings, wherein:

Fig. 8 is a detail showing in elevation the cooperable parts of the knee joints of the legs, and

Fig. 9 is a detail in'section' of an assembled knee joint.

As shown inthe drawings, the ironing board of my invention comprises a table made up of two hollow leaves it! and l I of substantially equal length, open at the underside thereof. The leaves to and H include flat horizontaltop portions it and 53 forming an ironingsurface'and vertical side walls i l and l5-in the'form' of depending fianges extending downward from the flat top portions to'form a pair of squat box-like structures with downwardly facing inner cavi- The leaves lt'and ll may beaadvantageously formed of sheet metal, or of plywood or other suitable material and the top portions 52 and it can be perforated if desired to facilidissipation of steam during ironing. Pref erably the rear leaf I6 is substantiallyrectangular, while the front leaf H is tapered: to a blunt nose 5% as is usual in ironing. boards. The abutting flanges ii and [8 of the leaves!!! and l! are. folded to form "triangular sections as shown in Figs. 3 and 4, and are joined at their owcr portions by a hinge I9 e. g. a piano hinge, 0 that the leaves can be folded-together with heir hollow undersurfaces facingeachrothenas .hown in Fig. 2,'and opened for useas shown in igs. l and 3. abutmentof the'fianges I l and I8 securely holding the leaves in extended position with their-top portions forming a single plane surface for ironing.

' Foldablesupport-means for the ironing: board comprises a plurality of legs which can be advantageously made of metal having a hollow square section, for example, a pair of legs being attached to the rear leaf I5 adjacent the rear end and on the flanges l4 thereof, and a single leg being attached to the front leaf N.

In accordance with my invention, rear legs "20 each include an upper section 21 and a lower section 22 of substantially equal length, joined at a hinge 23, the adjacent ends of sections 2! and 22 abutting each other at the hinge when the legs are extended for use, the hinge thus forming a knee joint, bendable only in one direction to collapse the legs.

Referring to Figs. 8 and 9, each hinge 23 comprises mating hinge parts 23a and 23b the shanks of which extend longitudinally into the hollows of the leg sections 2! and 22, and preferably said shanks and leg sections are welded together to provide a permanent, rigid assembly. ihe hinge parts 23a and 23b are pivotally connected together by a pintle 230. The upper ends 24 of the legs 29 are flattened and secured by pivots 25 to the inside of the flanges M of the rear leaf I 5, adjacent the rear end thereof.

A cross bar '25 joins the lower sections 22 of legs 2%. The cross bar is preferably formed of telescopic sections to be extensible, and comprises two relatively movable parts 2? and 28 slidably connected together as by engagement of a rod 29 on the end of part 28 slidably inserted into a bore 30 extending inwardly in part 2? from the end thereof. Stop means is provided for limiting the relative telescopic movement of parts 2! and 28, comprising, for example, a transverse pin 3! on bar 29, slidable between the ends of a transverse slot 32 in part 2?, intermediate the ends of the bore 39. A compression spring 33 bears against a shoulder 35 at the inner end of bar 29 and against the end of part 27, urging

parts

21 and 28 to extended position. By virtue of the spring 33, the cross bar 26 automatically spreads the lower ends of legs 26 to divergent position so as to provide added stability in supporting the rear end of the ironing board during use.

As indicated in Figs. 3 and 4, the lower sections 22 of legs 26 fold inward and upward against upper sections 2! about hinges 23, and the legs when folded are pivotally movable about their upper ends 24 to the position shown in Fig. 4 within the cavity. When thus folded, they are completely received within the hollow interior of leaf Iii. In order to accommodate the lower part of the leg structure to the width of the interior cavity of the leaf iii, cross bar 26 is longitudinally compressible against the pressure of spring 33 sufficiently to render legs 25!- parallel. When the legs are folded within the cavity, the pressure of the spring 33 urges the legs against the inner surfaces of the flanges l4 of leaf it, thus tending by reason of the increased frictional engagement of the legs with said surfaces, to retain the legs within the cavity.

In order to hold the legs 25 in extended position for use, a strut 35 is pivotally attached at one end, e. g. by means of a bracket 36, to the underside of the top portion I 2 of leaf l0 adjacent the hinge l9, and the other end of the strut is pivotally attached to the cross bar 26. Strut 35 comprises two

sections

35 and 39 joined at a hinge 36, to form a toggle which can be bent upwardly as shown by dotted lines in Fig. 3. The hinge 4B is similar to the hinges 23 described above. When the strut 35 and legs 20 are extended as shown in full lines in Fig. 3, the legs slant outward or rearward from the end of leaf i0, so that pressure transmitted from the ironing board to the legs tends to urge the abutting ends of sections 2! and 22 of the legs against each other, holding the knee joint at hinges 23 in rigid, extended position.

In order to permit folding of the legs 23 within the leaf II], the hinge 48 is arranged to break upwardly as shown. in Fig. 3, the section 38 pivoting about the bracket until it rests against the underside of the top portion I2 of leaf I6, while section 39 of the strut 35 folds inwardly against the section 38 to the position shown in Fig. The distance between the pivots 25 and brackets 36, and the lengths of the leg sections 2!, and of the

strut sections

38 and 39 are so arranged that the legs can fold to the position shown in Fig. 4 with the folded strut positioned behind the a.

To enable this to ibe accomplished, the cross bar 26 is connected at its ends to the legs at by plates 26a, thereby causing the bar to be offset inwardly therefrom as clearly shown in Figs. 1. and 3.

The pivotal connection between the strut section 39 and the cross bar 26 is accomplished as follows: The lower end 3912 of the strut section 35 is flattened and apertured. lhe part 2? of the cross bar is formed of two portion 27c and 212), the latter having a rod-like extension 210 passing through the aperture in the end 3960 of the strut section 39, and fitting into a bore Zia? in the portion 21a. A pin 21c secures the portions 2 1a and 27b together, leaving space between them as shown in Fig. 5 to accommodate the apertured strut end 39a.

The front leaf ll of the ironing board is supported by a single leg 4! comprising a lower section @2 and an upper forked section #3, the latter comprising, for example, a Y-shaped junction member 44, a stem 55 and a pair of arms @504 the upper ends of which are pivotally attached at it to the flanges i5 of the leaf I I adjacent the inner hinged end thereof. Sections 42 and :33 of the leg 41 are joined at a hinge 41 forming a knee joint by abutment of the ends of said sections in the same manner as in legs 28, the hinge d? be ing similar to the hinges if? and 23. The lower section E2 of leg M folds inward about the hinge 4'! as indicated in Fig. 3, so that the two sections when folded together can be swung upward about pivot 45 to a position within the cavity at the underside of leaf II.

To support the leg di in extended position, articulated braces #38 are pivotally attached by a bracket 49 to the underside of the top portion 93 of the leaf I i adjacent the nose 55 thereof, the opposite or lower ends of the braces being pivotally pin-connected to the leg section 5-2 intermediate the ends thereof. Each brace as com-- prises upper and lower sections 5% and Si respectively, which are pivotally connected together by a pin 52. The adjacent pin-connected ends of the brace sections 50 and have portions iiiia and 5m which are offset to abut each other an form a knee joint whereby said sections may be swung about the pins 52 toward each other in one direction only, to collapse the braces.

When the front leg Qi is extended position, it projects outwardly or forwardly from the leaf I I in an angular position diverging from the legs 20, with the h nge 4? on the inner or underside of the leg, so that 7 pressure transmitted from the ironing board tends to hold the knee joint formed by said hinge in rigid, extended position.

In order to fold the front leg within the cavity of theleaf- I Lthe lower sectionl lz is folded inwardly andupwardlyas indicated in-l ig. 3 about the hinge t1 and against the upper section 43. and the braces 48 are simultaneouslyfolded up- Ward toward-theunder surface-of the top por tion l3 of leaf H, whereupon the folded sections 22 and #3 of the leg-M will be automatically moved upwardly about the pivot .46 to the position shown in'Fig. 4, within the hollow under portion of the leaf 1 i.

The junctionnrember 44 has a pin l lc which guides the brace sections 553- during thecollapsing of the brace 48 and leg 4!, as shown in Fig. 3.

- When both sets-of leg structures are folded within the leaves is and H, the leaves can be folded together: to the position showniin Fig. 2 for convenient storing ortransportation thereof. Av handle 53 may be provided, for example on the flange IA of the leaf [0, to facilitate carrying the ironing board.

It will be seen that the ironing board of my invention constitutes a simple and-economical structure, adapted to be conveniently manufactured and manipulated, characterized by stability when set up for use, and foldable to a. compact form convenient for storing or transportation when traveling.

Variations and modifications may be made within the scope of this invention and portions of the improvements may be-used without others.
