Patented Dec. 15, 1931 UNITED STATES can A rommx, or PERU, INDIANA FOLDING IRONING BOARD Application filed March 13, 1929. Serial No. 846,887.

This invention relates to improvements in ironing boards or tables.

The primary object of this invention is the provision of an improved collapsible leg construction for supporting ironing boards or tables.

A further object of this invention is the provision of an improved leg construction for that type of iron table set forth in my co-pending application, Serial No. 189,365,

filed May 6, 1927, and embodying improvements thereover in the means for stabilizing the lateral and longitudinal positioning of the leg when in a set-up position.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawings, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a perspective view of the preferred form of improved ironing board and leg construction, showing the leg construction extended and supporting the board.

Figure 2 is a bottom plan view of the improved table construction, showing the leg construction collapsed upon the board portion thereof.

Figure 3 is a fragmentary sectional view taken substantially on the line 33 of Figure 1.

Figure 4 is a fragmentary sectional view taken substantially on the linev 4-4.- of Figure 1'.

Figures 5 and '6 are bottom plan view showing successive steps in the extension of the legs for table supporting purposes.

Figure 7 is an enlarged view showing the table connected portion of one of the leg constructions with the arts positioned as shown in Figure 5, and prior to full extension of the legs.

Figure 8 is a View showing the arts of Figure 7 in their final adjusted an braced relation, when the legs are in their triangular relation shown in Figure 6, for table suport. p Figuer 9 is an enlarged sectional view taken substantially on the line 99 of Figure 8.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the letter A may generally designate the improved ironing board or table construction, which ma include the ironing board or table proper having le constructions C and D foldably 35800181185 therewith.

The ironing board or table portion B is of course of ordinary construction, elongated and preferably of wood.

The leg construction C preferably comprises the

leg members

15 and 16, of any approved material, having bolts or pins 18 in the upper ends thereof loosely bearing at 66 the inner sides of the

legs

15 and 16, in the depending ears 19 of an inverted U-shaped bracket 20 which is bolted or otherwise secured at 21 to the board B on the under surface thereof and at one end thereof. This 70 type of pivot connection is shown in Figure 3, and is very economical; the facing ends of the bolts being sufliciently long that they have an oscillative or rather universal bearing in the openings of the depending ears 76 19. This permits the

leg members

15 and 16 to move towards and away from each other at their free ends, transverse to the longitudinal axis of the board, and permits the

legs

15 and 16 to be swung to collapsed 80 position beneath the board B parallel therewith, or to an extended substantially normal position with respect thereto.

In order that the

leg members

15 and 16 may be properly braced when in an extended downwardly divergent relationship for supporting the ironing board B, that is, in the position shown in Figure l,'it is preferred to provide braces 25 and 26, each of which includes a major portion 27 pivoted at its lower end at 28 on the rear surface of one of the

legs

15 or 16, as the case may be, and

a minor portion or piece 29 pivotally connected at 30'0n the rear surface of the

under leg

15 or 16, as the case may be, at a loca-- tion closer to the pivot of the

legs

15 and 16 of the pivot location 28 above described. The portions 27 and 29 are relatively pivoted at 31, at their proximate ends. Each of the braces 25 and 26 thus includes a pair of ends of the latter. The leg is relatively pivoted parts, one of which is connected at its free end to one of the legs and the other of which is connected at its free end to the other of the legs, so that the parts of each brace when extended and the

legs

15 and 16 in braced board supporting position will be diagonally arranged. The braces 25 and 26 cross each other in an X- shaped relation. The portions of the braces 25 and 26 bend at their pivot 31 in the direction of the longitudinal axis of the board, to permit the

legs

15 and 16 to be colla sod from a divergent position to a position w iich will enable them to be collapsed beneath the board. This is part of the leg construction set forth in my co-pending application and need not be further referred to, except to state that asubstantially U-shaped guard 35 is provided for each brace 25 and 26, at the pivot 31 thereof, to limit the bracing position of the braces 25 and 26, and permit the same to be collapsed in one direction on lly.

he leg construction D comprises a single supporting leg 40, pivotally connected b means of a horizontal pin 41 to the depen ing ear portions of spaced angle clips 42 attached to the under surface of the ironing board B, substantially midway between the ivoted so that it may be collapsed parallel eneath the ironing board B, or extended downwardly in a divergent relation, at an acute angle with respect to the plane of the ironing board B, in a sloping relation away' from that end to which the leg construction C is pivoted, as shown in Figure 1. As is shown in Figure 9, a stop block or cleat 44 is secured at 45 on the under surface of the board B, rearwardly of the pivoted connection 41'of the leg 44; the said block 44 having a forward beveled edge-47 against which the top edge of the leg 40 abuts when in position, to support the board B.

The leg constructions O and D are connected for synchronous collapsing and board supporting movements by means of a link construction 50, which consists of lengths of wires 51 and 52 connected at their forward ends by a cross portion 53 which is pivoted in a socket 54 upon the free end of the leg 40; the wire lengths 51 and 52 extending rearwardly and at their opposite ends being inturned and pivoted at 54 and 55 respectively to the

legs

15 and 16, closer to the ivot ins of said legs than their free ends. he pivot connections 54 and 55 are preferably detachable, and the wire portions 51 and 52 of the link construction 50 are adapted to extend parallel along the outer sides of the

legs

15 and 16 respectively, when in collapsed position beneath the board; the link construction 50 when the legs are in a setup position extending diagonally downward from the upper portion 0 the leg construction C to the lower end of the leg 40, as shown in Figure 1. The connections 54 and 55 are of course )ivotal, so that merely by movement of the eg construction C, the leg member 40 will be moved to an extended or collapsed relation therewith, or vice versa.

A releasable bracing construction is provided, to releasably brace the leg constructions in an extended rigid relation. This bracing construction 60 includes

brace members

61 and 62, preferably of wood, pivoted by pins 64 to the inner sides of the

legs

15 and 16, at locations between the respective pivots 28 and the respective pivots 54 and 55 of the link construction 50. The

brace members

61 and 62 extend in the general direction of the pivot of the leg 40, and near their free ends they are relatively connected by means of a flexible wire link 65. This link 65 includes the side portions 66 and 67, which are relatively connected at 68 and pivoted on a clip 69 secured to the under surface of the board B, along the medial line thereof, and spaced forwardly from the pivot connection of the leg 40. This U-shaped link 65 at the free ends of the portions 66 and 67 thereof is provided with oppositely turned feet 70, pivoted in the brace members 61 and 62 a short distance from the free ends of said

members

61 and 62. The U-shaped link 65 is of such nature that the portions 66 and 67 may flex, and the portions of the

brace members

61 and 62 from their pivot connection 70 to the free edges 73 of said brace members, lie in spaced relation laterallv of the portions 66 and 67, as shown in Figure 7 of the drawings. 1

A pivoted cross clip is bridged between the connections 70; the said clip 80 being of U-shaped formation, and having spaced ears at the inner sides of the

brace portions

61 and 62, pivoted to the connections 70; the said body of the cross clip 80 lying to the rear of the leg 40, and being adapted to be braced thereagainst, as shown in Figure 9 of the drawings when the legs are in a setup position. Furthermore, this clip 80 limits the spreading movement of the

brace members

61 and 62, and enables them to function in a proper bracing relation. To better bring out this relation of parts, it should be observed that the legs C and D are initially extended to the position of parts shown in Figure 5. in which case the leg 40 of the construction D is fully extended, and the

legs

15 and 16 are extended, but not laterally moved to their full position. In this position of parts'as shown in Figure 5, the

brace members

61 and 62, and the other connection of parts will be as shown in Figure 7. Moving the free ends of the

legs

15 and 16 apart to the position shown in Figure 6, so that the braces 25 and 26 therefor may hold them in such extended relation, causes the

brace members

61 and 62 to pivot on the ends of the cross brace so that the free end portions of the

brace members

61 and 62 beyond the clip 80 will move from the position shown in Figure 7 inwardly to the position shown in Figure 8. During this movement said end portions of the

braces

61 and 62 will move into en agement with the upper surfaces of the sicIe portions 66 and 67 of the connecting link 65, causing them to be distorted slightly to the position shown in Figures 8 and 9, and enable a better locking action of the parts, to prevent any free play or lost motion in said parts, and efficiently bracing the same. Under these circumstances it should be noted that the pivot connections 7 0 lie inwardly of a straight line drawn between the pivot'of the link 65 on the clip 69 and the pivots'of the

respective braces

61 and 62 at 64 upon the

legs

15 and 16. There will thus be o tendency of the

braces

61 and 62 to move 511m their bracing relation, but there will be a firm tendency during support of the board to engage the cross clip 80 against the leg 40, to enal ile a good bracing of parts. In this conne'g tion it should be noted that the head 511 f: a screw or member is positioned on the leg 40 to prevent the stop 80 from falling from the position in which the

braces

61 and 62 are locked past their dead center position.

Furthermore, as an important aid in the bracing of the parts, a stop cross cleat is provided, secured at 91 in a transverse relation upon the under surface of the board B,

at a location between the pivots of the members 65 and leg 60 onthe board, and at a posi tion so that the free ends 73 of the braces 61 1 and 62 will engage thereagainst when the legs are in a full extended relation, to relieve strain upon the connecting membenfiii, and enable a very rigid bracing of parts. This can very well be understood from Figures 8 and 9 of the drawings.

The parts collapse as shown in Figure 2, with the

braces

61 and 62 collapsed parallel at the inner sides of the

legs

16 and 15 respectively. The leg 40 collapses along the longitudinal center of the board B,,and said leg is provided with a latch 98 pivoted between its ends at 99 and movable to a position where it will transversely engage the collapsed

braces

61 and 62 and the

legs

15 and 16, as shown in Figure 2. When it is necessary to set up the board, the latch 98 is swung to a positlon in alignment with the leg 40, and by grasping either of the

legs

15 or 16, and moving the same to the position shown in Figure 5, the leg 40, brace constructions 50 and 60 will be moved therewith to the position shown in Figure 5. The

legs

15 and 16 are'then spread apart and braced with the braces 25 and 26 extended, at the position shown in Figure 6, and this will move the

braces

61 and 62 near their pivotal ends into the rigid bracing and securing relation shown in Figures 8 and 9 and above described. When the leg constructions are being collapsed it is necessary to collapse the braces 25 and 26, swin the

legs

15 and 16 inwardly together, am? lift upwardly upon either of the

braces

61 or 62, to move them past a dead centered position between the end pivots of the brace construction 60, and to lift the cross detent 80 alon the leg 50 past the retainin head or mem er 85. The legs will then co lapse into the same plane, and in this connection it is to be noted that the legE l'Q, the braces- 61 and 62; the legs 15 and 16 {and the wire braces 51 and 52 of the linkgQsf-all; collapse in the same plane parallel immediately beneath the board B, and are latchedifthereagainst by the latch 98 above described.

Various changes in the shape, size, and arrangement of parts may be made to the form of invention herein shown and described, without departing from the spirit of the invention or the scope of the claims.
