2 Claims. 1

My invention relates to a collapsible support for an ironing board and has for its primary object the provision of a support which lends itself to fabrication from metaltubin'g and sheetmetal stampings. A fu-ith'erobject of my invention is to produce an lining-board support which may be easily and quickly Etollapsed or extended and. which, when "e'xtei'ic'led', will be stable and rigid.

In carrying out my invention I secure on a common axis-near the rear end of the ironingboard top a pair of rear legs; and at a point intermedi'ate the length or the ironing-board top I pivotally attach theretoa front leg adapted when the support is erected to extend forwardly and downwardly. 'Ea'ch'of the rear legs is connected by a link to a pointnear'th free end of the front leg so that both thefroritlegs and the rear legs will move jointly to and'i-rom extended position. To hold the board in extended condition I provide a brace connected to the front leg near the free end thereof and extending upwardly and rearwardly into 'slidable association with a latch member pivotally attached to the ironing board top near the rear end thereof; The brace and latch member have releasable cooperating provisions which operate when engaged 'to hold the legs extended; The legs; both front and rear, are desirably formed of metal tubing, the links and brace may be in the forin of metal rods or tubing, and the latchmeinber is desirably a sheet-metal stamping The accompanying drawings illustrate my invention: Fig. 1 is a side elevation of the ironingboard in e'xtende'd'condition'; Fig. 2 is an elevation of the ironin'g -board showing the legs and other parts in collapsed condition; Fig. 3 is a side elevation ofthe ironing-board illustrating the legs in partially extended condition; Fig. 4 is a rear elevation of the erected ironing-board; Fig. 5 is a fragmental vertical sectionon an enlarged scale showing the s emm ng brace and latch member; and Fig. '6 is a rear elevation of the brace in latched condition.

The ironing-board top illustrated in the drawin'g "comprise's'a'b rde'r frame ll] of met-a1 tubing covered with a "plurality or sheet-metal 'panels H extendingtra versay of the border frame- HI and secured to the sides thereof. Near the rear end of the border frame, there is a cross-member l 2, desirably in t e former a sheet-metal stamping of channel c'rc's' ection. 5A sir'nilar crossmember I3 extends between the sides of the bogder frame intermediate the length thereof. To strengthen and stiffen the top, it embodies a truss-like brace 15 extending beneath and secured to the cross-members l2 and I3 and haying its ends bent upwardly a secured to the ends of the border "frame. The particular top illustrated, which forms no part of my present inention, embodies sonic features more fully 'de: scribed and claimed in prior Patent No. 2,442,676, granted ane "1, 1948.

The top-supporting structure, which forms the subject matteio'f the present 'i'nventionembodies a pair of rear legs z'oeach pivotally attached at one end to the rear cioss ine'inber I 2 of thetop'. To effect this attachmeht in a Simple and B nomical manne'r, ears 2-1 are struck up from the web of the cross member 12' and pierced for the reception of a pivot ism or bolt 22'. The pivotal connection of each of tll rear legs '20 is through a loose connection or one so arranged that the legs are not constrained to movement in a plane normal to the ironing board top.

The front leg, designated in its entirety by the reference numeral "2 5 ,"is desirably formed from a single length of metal tubing bent to provide a narrow elongatedU-shaped portion 26 (Fig. ,2), diverging portions 27, and parallel end portions 28. The end portions of the front legs are pivotally connected to the front cross member l3, as through pivotpins or bolts 29 extending through ears 2! on such cross member.

The fron le 25 is connected by a link 3| to each of the rear legs 20, so that both the front and rear legs maybe moved jointly from 001- lapsed to extended position. The length of each link M is such "and its points of connection to the front and rear le'gs ares'o' disposed that while the two legs will occupy substantially coplanar positions when collapsed the rear legs 20 will swing through a; much greater angle than the front leg 25 as the legs are extended. Preferably, the legs are arrangedso that when extended the rear legs will slope downwardly and rearwardly from their point of connection to the top, as will be clear from Fig. 1.

Each of the rear legs hasassociatedwith it a brace 33 pivotally 'c'dhn'ctd at one end to the leg by a pivot pin or bolt 34 which is so disposed so that it lies approximately normal to the plane of the top when the legs are collapsed. The opposite end of each brace is connected, as by a pivot pin or bolt 35, with an car 36 struck up from the rear cross member l2 near the middle thereof. As will be clear from Figs. 1, 2, and 3, the pivot pins 35 are not coaxial with the pivot pins 22, but instead are disposed rearwardly of the pivot pins 22. As a result of this relative disposition of the

pivot pins

35 and 22, the legs 29 when collapsed against the lower surface of the top are generally parallel to each other but when extended diverge from each other, as shown in Fig. 4, to increase the effective width of the ironing-board base and hence increase stability.

For the purpose of releasably holding the board in extended condition, there is pivotally attached to the rear cross member l2 a latch member 40 which slidably receives a brace 41 extending from the latch member 40 to the free end of the front leg 25 to which it is pivotally connected. The latch member 40 is desirably formed as a sheetmetal stamping of channel-shaped cross-section. At its rear or upper endpthe flanges of the channel are provided with extensions in the form of ears 42 which receive between them and are pivotally connected to the brace IS on the ironing-board top. In advance of, or below, the ears 42 the upper edges of the flanges of the stamping constituting the latch member are bent inwardly to form lips 43.

The brace 1!, which is desirably formed of metal tubing or metal rod, extends longitudinally completely through the latch member 4!) and is provided in rear of such latch member with a downwardly extending, forwardly presented shoulder 45. In advance of the latch member, the brace l! is provided with an abutment 4B limiting upward, or rearward, movement of the brace in the latch member. The distance between the shoulder 45 and abutment 46 is substantially equal to the length of the latch member, as will be clear from Fig. and the fit of the brace within the latch member is sufliciently loose to permit the shoulder 45 to be received within the latch member.

When the ironing-board is in collapsed position, the legs 2! and 25 are disposed in substantially coplanar relation against the bottom of the ironing-board top in-the manner illustrated in Fig. 2. With the legs in this position, the brace M and latch member 40 occupy the respective positions illustrated in chain lines in Fig. 5. When it is desired to extend the support, the free ends of the legs are moved away from the top toward and through the position illustrated in Fig. 3. As this movement progresses, the brace l! moves rearwardly in the latch member tll until the abutment 46 engages the end of such latch member. The abutment 46 is so located on the brace t! that when it engages the end of the latch member to limit swinging movement of the legs, the legs will be in the position which they occupy when the board is erected. If the brace M is now moved laterally of itself to cause engagement of the latch 45 with the rear end of the latch member 68 the legs are now positively held in their extended positions.

Conveniently, the ironing board is erected with the top in the vertical position shown in Figs. 2 and 3. Extension of the legs may be instituted by moving the free end of one of them away from the top or by tilting the top so that the two legs will fall away from it under the influence of gravity. With the board anywhere near the vertical position shown in Fig. 3, the force of gravity acting upon the lower end of the brace M will tend to cause the shoulder 45, as soon as it has cleared the rear end of the latch member 40, to drop into engagement with such latch member. Whatever procedure is followed to extend the legs and engage the shoulder 45 with the rear end of the latch member 40, such engagement with the latch member will locate the legs in extended condition and the board may then be rotated into its normal position about the outer ends of the rear legs 2!].

To collapse the board, it may be rotated about the lower ends of the legs 20 until the rear end of the top engages the floor, and the brace M then moved to disengage the shoulder 45 from the latch member 45, whereupon the legs may be jointly swung into position against the lower face of the top. A modified procedure for collapsing the board is merely to lift and release the rear end of the brace 4| when the board is in erected. condition. This permits the front end of the ironing-board to drop against the front leg 25 under the influence of gravity, the free end of such front leg remaining on the floor, the brace sliding through the latch member 40, and the rear legs 20 swinging into coplanar relationship with the front leg.
