E. E. FOSTER Aug. 9, 1966 IRONING BOARD 2 Sheets-Sheet 1 Filed Oct. 5, 1964 'IIIIJ INVENTOR. EDWIN E. FOSTER United States Patent 3,265,017 IRONING BOARD Edwin E. Foster, Austin, Tex., assignor to Majilr-Ironers, Inc., Austin, Tex., a corporation of Texas Filed Oct. 5, 1964, Ser. No. 401,362 7 Claims. (Cl. 10882) This invention relates to ironing boards and more particularly to a board provided with a folding corner to rfunction selectively as :a full rectangular board or as a tapered end board.

'In my Patent No. 2,729,005 I have provided -a board of the general type to which the present invention relates and which has a sheet metal triangular corner piece hinged to a sheet metal board to swing through an angle of approximately 180 from a position coplanar with the board to a folded position beneath the board. The present invention provides an improvement in boards of this gen eral type in which the board may be formed with an edge flange to provide adequate strength therefor without interfering with folding of the corner piece.

An object of the invention is to provide an ironing board in which the triangular corner piece is connected to the board through a connector strip hinged to the board and to the corner piece to overlie the edge of the board and to permit the corner piece to swing to a flat position beneath the board. This construction further provides the advantage of two 90 bends at spaced points rather than a single 180 bend thereby allowing the cover and pad to fold more easily with less likelihood of damage.

According to another feature of the invention, the board may be made in the same way by the same tools to be sold either with or without the corner piece and connector strip thereby resulting in substantial manufacturing economy. The above and other objects and features of the invention will be more readily apparent from the following description when read in connection with the accompanying drawings, in which:

FIG. 1 is a perspective view of a complete ironing board embodying the invention;

FIG. 2 is a top plan view of the board with the top surface removed;

FIG. 3 is an enlarged ipartial section on the line 33 of FIG. 2;

FIG. 4 is a section similar to FIG. 3 showing the corner piece in folded position;

FIG. 5 is a view similar to FIG. 3 of an alternative construction;

FIG. 6 is a view similar to FIG. 4 of the alternative construction; and

FIG. 7 :is a partial perspective view of a portion of the corner piece and connector strip.

The complete board, as shown in FIG. 1, with the exception of the novel foldable corner construction is generally conventional and comprises a flat ironing board 10, preferably formed of sheet metal with a porous or perforated top and which is supported on hinged legs 11. The legs are connected to cross pieces 12 which carry foot members 13 and are foldable from an extended position, as shown in FIG. 1, to a folded position in which the legs closely underlie the board for storage. Since this mechanism is conventional and forms no part of the present invention, it will not be further described herein.

The board is of generally rectangular configuration but is cut away at one corner along a sloping line 14 which is at an acute angle to the length of the board and which extends from a point intermediate the width of the board at one end thereof to a point at one side of the board spaced from but adjacent to said one end. The board may be formed of an outer sheet metal frame 15, as shown in FIG.'2, with 'a separate cover sheet of expanded or perfo- "ice rated metal secured thereover. According to the present invention, the frame 15, as best seen in section in FIG. 3, is of generally channel shaped configuration and extends downwardly at right angles to the upper surface of the board with upper and lower flanges thereon which are bent inwardly. Preferably, at least along the edge 14, the frame 15 is bent in section to provide a short portion 16 lying at an acute angle to the lower flange 17 thereof to cooperate with latching and bracing structures, as described more fully hereinafter. The board may be reinforced by cross braces 18 and by a diagonal corner brace 19, as shown in FIGS. 2 and 3. The corner brace 19 may have a latch pin 21 projecting therefrom for a purpose to appear more fully hereinafter.

The board is completed by a relatively narrow connector strip 22 hinged at the edge 14 of the board and a triangular corner piece 23 which is hinged to the strip. The strip and corner piece may be raised to a position coplanar with the top of the board, as illustrated in FIGS. 1 to 3, to make a full rectangular ironing board for ironing relatively large objects or may be folded under the corner portion of the board along the edge 14, as shown in FIG. 4, to provide a relatively narrow point on the board for ironing small tubular articles. The connector strip 22, as best seen in FIGS. 3 and 4, is formed of sheet metal of a width approximately equal to the thickness of the board frame 15. For hinging the connector strip to the board frame 15, the frame is formed at the juncture of the top flange 24 of the frame and the edge portion thereof along the line 14 with a series of openings, as seen at 25 in FIG. 2. The connector strip 22 is formed with a series of tabs or lugs 26 pressed therefrom and extending at a right angle thereto which extend through the openings 25 to define a hinge connection therebetween.

In a similar manner the triangular corner piece 23 is formed at the edge thereof which abuts the connector strip with a series of projecting ears or tabs 27 which extend through openings 28 in the opposite edge portion of the connector strip 22 to define a hinge connection therebetween. As will be noted from FIG. 3, the ears or lugs engage the adjacent flanges on the adjacent part when the connector strip and corner piece are in their erected position coplanar with the upper surface of the ironing board to assist in maintaining proper alignment between these members. It will be apparent that the ears or lugs 26 and 27 could be provided with short slots adjacent to their connection to the piece on which they are carried so that by a slight lateral shifting they would be locked in place in which they are received against accidental removal.

in order to hold the corner piece and connector strip in erected position a latch mechanism is provided. As shown, this comprises :a strut 29 pivoted at one end at 31 to the lower surface of the corner piece at a point spaced from its hinge connection to the connector strip. At its opposite end the strut is formed with a short flange 32 which will fit under the edge flange 17 of the frame so that the end of the strut can abut the angular flange portion 16, as shown in FIG. 3, to hold the corner piece and connector strip erected. A spring 33 is connected to the strut tending to urge it upwardly so that the latch will automatically engage when the corner piece is raised.

In order to release the latch to permit lowering of the corner piece a finger lever 34 is hinged on the axis 31 and carries a pin 35 at its inner end engaging the upper edge of the strut 29. A leaf spring 36 secured to the finger piece engages the bottom of the triangular corner piece 23 normally to hold the finger piece in the position shown in FIG. 3. To release the strut or latch the finger piece may simply be squeezed by an operator which will cause the pin 35 to engage the strut 29 and swing it downwardly to clear the (corner of the frame.

At this time, the connector strip and corner piece can u. be folded under the corner portion of the board, as shown in FIG. 4. It will !be noted that the connector strip 22 spans the thickness of the frame so that the corner piece 23 can be folded under the board and closely adjacent to the undersurface thereof. To retain the parts in this position the corner piece carries a spring clip 37 which will :frictionally engage the pin 21.

Preferably a compression spring 38, which may be of the type more particularly described and claimed in my Reissue Patent No. 23,974, is connected between a lug 39 secured to the undersurface of the board top and the lower edge of the ears or lugs 26 on the connector strip. This spring will insure that during folding in of the corner piece and connector strip the corner piece will first bend 90 relative to the connector strip and the connector strip will then bend 90 relative to the frame to position the corner piece properly beneath the board. This insures a proper sequence of bending movements and eliminates any possibility of binding in the hinge joints.

With the construction as so far described it will be seen that the corner piece is 'folded under the board through two spaced 90 bends rather than through a single relatively narrow hinge which hinges through 180". This makes it easier to fold the corner piece with a pad and cover in place on the board and minimizes stretching and likelihood of damage to the pad and cover piece through breakage due to excessive bending. The construction is at the same time relatively simple and inexpensive and is extremely easy to use.

FIGS. 5, 6 and 7 illustrate a modified construction wherein the frame of the board, at least along the fold line 14, is formed of a special configuration. As shown in FIGS. 5 and 6, the frame at this point. comprises upper horizontal flange 41 which joins and supports the board top 42. The frame portion is bent down in a flat strip 43 at a right angle, to the flange 41 throughout approximately one-half the thickness of the board and then curves inwardly in an arcuate portion 44 which terminates in a flat bottom flange 45. A brace 46 corresponding to the brace 19 of FIGS. 1 to 4 is secured to the flange 45, as shown, and may be in the form of a tubular rod.

A connector strip 47 is hinged to the edge strip by means of ears or lugs 48 on the connector strip projecting through openings in the edge strip at the juncture of the flange 41 and flat edge portion 43 thereof. These ears or lugs are of such a length that when the connector strip is in coplanar relationship with the ironing board tolp they will rest on the arcuately curved portion 44 to hold the connector strip at the same level as the flange 41. At its opposite edge the connector strip has a downwardly turned flange 49 terminating in an inwardly turned strip 51 and is provided with a series of slots 52 at the juncture of the upper surface 47 and flange 49. One of the slots, as shown at 53, is preferably provided with a short extension 54 to provide interlocking engagement between the corner piece and connector strip, as described hereinafter.

The board is completed by a triangular corner piece 55 which is formed at its edge with a series of downwardly projecting ears or lugs 56, as best seen in FIG. 7. These ears or lugs are formed with short notches 57 at the point where they join the corner piece so that they can be inserted through the openings 52 and shifted slightly to interlock with the openings to prevent accidental removal. One of the lugs, as shown at 58, is provided at one edge with a short extension 59 terminating in a square shoulder 61 and this lug is adapted to cooperate with the specially formed slot 53 in the corner piece. By bending or wanping the corner piece slightly when the parts are being assembled, the tapered projection 59 can be forced through the opening 53 with the shoulder 61. engaging one end of the opening to hold the corner piece against accidental shifting relative to the connector strip which might tend to align the lugs with the openings so they could accidentally be removed therefrom.

The corner piece is latched in its raised position by a strut or prop 62 hinged thereto at 63 and adapted to engage the lower edge of the curved surface 44, as shown in FIG. 5. A mousetrap type spring 64 is connected to the strut or prop urging it upwardly so that it will properly engage the lower edge portion of the frame to hold the connector strip and corner piece in their raised positions.

To release this latch a U-shaped spring 65 is looped over the top of the strut 62 and beneath extensions of the hinge pin 63. The end of the U-shaped spring is received in a guide slot 66 in a finger piece 67 which is hinged or hingably connected to the corner piece adjacent to the corner edge thereof. When the finger piece 67 is :raised the spring 65 will urge the strut 62 downwardly to clear the frame so that the corner piece and connector strip can be folded under the board, as shown in FIG. 6. The parts are held in the folded position by a spring clip 68 which friotionally engages the brace 46. It will be noted that in the folded position the flange 49 and edge strip 51 of the connector strip are received in the external cavity defined by the arcuate edge portion 44 so that adequate clearance is provided. When the connector strip and corner piece are raised, the lower ends of the ears or lugs 48 will ride easily over the convex surface of the curved edge portion 44 of the frame to insure that the connector strip moves upward to the same level as the flange 41 of the frame. Similarly, the ears or lugs 56 of the corner piece Will ride over the inturned edge 51 of the connector strip to insure that the corner piece and connector strip are at the same level. In this construction, as in that of FIGS. 1 to 3, the corner piece is folded under the board in two bends, rather than in a single bend, so that the pad and covering on the board can fold easily with less likelihood of damage. It will further be observed that with both constructions the board can he made in exactly the same manner for use either with or without a :corner piece thereby minimizing the tooling required.
