EXTENSIBLE IRONING BOARD 2 Sheets-Sheet 2 Filed Oct. 15, 194'! \NVENTOR guilt H. CLARK ATTORNEYS Patented Jan. 10, 1950 1 UNITED STATES PATENT OFFICE This invention is directed to a novel and very useful structure of ironing board. With the invention the horizontal upper board, uponwhich articles to be ironed are placed, is at a lower level than in the usual ironing board so that the one operating the iron may sit down while at work. As the operator will stay substantially in the same place, the board is mounted for movement back and forth in the direction of its length, thereby moving the articles on it to bring new surfaces at the place of those previously ironed. In efiect, this is a reverse of the normal practice where the board is stationary and the operator moves to difierent positions along side of it.

It is a primary object and purpose of the present invention to provide a very practical, sturdy construction, one which is very effective and durable in service, and which may have the article carrying board member readily moved to difierent positions, being releasably held in a number of positions to which it is moved and which, when not in use, may be folded to occupy a minimum of space. The parts from which the structure of the ironing board is made are of metal, except the upper board member itself. All are readily fabricated with economy, and the assembly to make a complete structure is easily accomplished.

An understanding of the invention may be had from the following description, taken in connection with the accompanying drawings, in which,

Fig. 1 is a side elevation of the ironing board of my invention in folded position,

Fig. 2 is a similar elevation with the ironing board structure unfolded an din its operative position,

Fig. 3 is an end elevation thereof,

Fig. 4 is an under plan view and section end portions of the upper board broken away, the plane of the section being substantially on the line of plane 4-4 of Fig. 2,

Fig. 5 is a horizontal section substantially on the plane of line 5-5 of Fig. 2,

Figs. 6 and '7 are fragmentary enlarged transverse sections substantially on the planes of lines 66 and 'l1, respectively, of Fig. 4, and

Fig. 8 is a fragmentary enlarged side elevation of the releasable bracing means for holding the supporting structure and upper board member in operative position.

Like reference characters refer to like parts in the different figures of the drawings, and the sections are taken looking in the directions indicated by the arrows.

The upper horizontal board member I prefer- 2 Claims. (01. 38 -103) is located over two parallel bars 2 of the Z-bar form (Fig. 6 and 7) which serve as supporting tracks for longitudinal movement of the board thereover. Plates 3, with retaining tongues struck therefrom, are secured to the underside of the board, the tongues passing underneath the outer flanges of the bars 2, making a sliding connection of the board'to the bars.

The bars 2, adjacent the middle portion thereof, are connected by cross bar 4 which is flanged at one edge for reinforcement, and spot weldedto the upper sides of the inwardly extending flanges of the bars 2. Two other cross bars 5, one near one of the ends of the bars 2 and the other a short distance from the other ends (Fig. 4), are connected to the under sides of the inner flanges of the bars 2, and each at each end has a downwardly extending car, as best shown in Fig. 3.

Supporting legs 6, four in number, are pivotally. connected at their upper ends to the downwardlyv extending ears on bars 5. The legs in pairs are connected together by upper and lower cross bars I spot welded thereto (Fig. 3). Between the upper and lower bars I a bar 8 of the form best shown in Fig. 5, wider at one end than at the other, extends between each pair of legs. Said cross bars 8, at their wider ends, are connected by a horizontal angle bar 9 spot welded thereto. The narrower ends of the cross bars are pivotally connected to the legs 6 at one side of the supporting structure and the bar 9, adjacent its ends,

is similarly connected to the legs 6 at the opposite side, so that relative turning movement of the bar 9 and the legs 6, about horizontal axes, may take place.

A bracing link construction includes two links l0 and H overlapping at adjacent ends and pivotally connected together. The link H is pivotally connected at its opposite end to the bar 9 and the link ill is pivotally connected at the pivot which connects one of the legs 6 of the downturned ear of its associated cross bar 5 (Fig. 2). The link In at the end portion thereof where pivotally connected to the link ll extends beyond the pivot (Fig. 8). Cooperating stops I2 and a projection l3 and recess |3a to receive it are formed on the links l0 and II so that when they are in alinement, as in Fig. 2, the supporting legs 6 are held in their vertical supporting position. But by folding the links In upwardly, th supporting structure may be brought underneath and substantially parallel to the board I as shown in Fig. 1. In this position it occupies a minimum of space.

It 88 The inwardly extending flange of one of the 3 track bars 2, at three spaced positions in its length, is notched to make notches M as shown (Fig. 4) A latch bar [5 of flat metal is mounted transversely of and at the under side of the board l by screw and slot connections of conventional form (Fig. 4) The latch bar 15, adjacent the notched edge of the track 2, is formed with a downwardly extending U-projection 16 which, at the outer leg thereof (Fig. 6) may ride against the inner edgeiof theiflange of :the-track bars? in which the notches 4 are made. When opposite one of said notches, the latching or locking bar [5 is normally moved by a tension spring IT to enter the notch to which it comes and hold the'part:l from movement on the track bars 2. The latching bar l5 has a down-turned hand engaging portion l5a at the end nearest thesidelof the board at which the one ironing is seated. By pulling outwardly on the handle portion "l'5a,the latching bar may be moved to release the board I for longitudinal :movement ".upon the xtra'ckibars 2 until theme-xi: notch lldl'isz-reachemby the downward :U portion l.
