My present invention relates to an ironing board structure. g I

The object of my invention is to prov de an ironing board structure including a boarpl of 111 0 a wall case when not-in use.v I I More particularly, it is my purpose provide a combination structure in which an ironing board may be folded into a case, which is close to the floor, so as to permit the board to be installed'where head room is limited. V

Another purpose of my invention s to provide such a structure which can be installed in a wall betweenstudding of standard spacing p I g A further object .lStO provide a structure including a case member which may be hung as a door of a closet or cabinet and may also serve as an adjustable support tor the ironin board. g l V Still another object is to provide n such a structure an ironing board readily and quickly adjustableto' proper heightby the same manipulation which sets the ironing board in position for use.

An additional purpose is to provide suitable means for locking the board in ironing position, so that it can not accidentally fall down.

Still another purpose 18 to provide such a structure that the ironing board support also serves as a door and thus eliminatesthe necessity for other hinged doors, which might otherwise take up wall space or nterfere with the use of the board. I

Anotherpurpose is to provide in the con hination an adjustable sleeve board which is readily demountable. r

Finally, it is my purpose to provide such a structurehaving partsso constructed and arranged as to afford a rig d support for the ironing board when in use, and wh ch is yet easily and conveniently handled and adjusted. 1 Y

With these and other objects in view, my invention consists in the construction, combination and arrangement of my ironing board structure, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective View of an iron ing board structure embodying my invention.

parts being broken away and parts being shown in section to illustrate the locking device; and I Y Figure 10 is a detail, longitudinal sectional.

.view through the inner part of the ironing g u I u L board illustrating the locking device.

It may be mentioned that my improved structure may be built as a unit in the factory so that it can be s'hippedand installed as a unit.

In the drawings herewith, I have shown a case, which has the panel 10 forming a back member, the forwardly "extending shallow side jambs or walls 11, the head jamb or wall 12 and the bottom jamb or wall 13.

The face of the case is trimmed with casing 14.

The inner faces of the side jainbs 11 iii the lower *parts thereof are provided with grooves 16 in which are inset metal channels 18. Near the upper portion of each channel 18, the bottom of that channel and the jamb beyond itare provided with a series of vertiparts from Lil cally spaced holes to receive the locking bolts hereinafter referred to.

Secured. to the inner faces of the side jambs 11 at the tops thereof near their front edges are wear plates 22 shown in Figure 2. Holes extend through the wear plates 22'and into the j'ambs 11.

In the inner faces of the jambs l1 spaced 'rearwardly from the holes 24 are holes 26 (see Figure l) to receive the locking boltsof provided at what is its lower end when the parts are folded up into the case with a locking deviceand the door member 30 is provided with a locking device, which is similar, except for the springs to be hereafter mentioned. I

I shall now describe this locking device. For convenience, it may he said that in referring to the upper and lower partsof the various elements, I am referringt'o them when in their closed positionas shown in Figure 3.

In the lower end of the ironingboard 36, there is cut clear across the board a groove 40, which is partially filled by a spline 42 glued into the groove, so as toleavea trans verse opening 4 across the board. V (See Figures 2, 9 and 10.) I 1 A hole is cut through the heard as at 46 to bisect the passage 44. The ends of the hole 46 are closed by discs A and I) which rotate freely in the holes.

The disc B comprises a disc-like sheet of metal e8 rigidly secured to a second discshaped piece of metal 50 havingthe annular iii-turned flange 52 received in the hole Q6.

The disc A consists of a disc-like sheet of metal 54: having an out-turned annularfiange 56 received in the hole 46 and a disc member 58 of greater diameter, having a central cupped portion 58 securedto the portion 54.

A key 60 has two legs 62 extending through the discs A and-B and receiving the'lock nuts 64. The legs 62 extendrespectively through the offset ends 66 and 68' of locking bolts or

rods

70 and 72 slidably received in the passage 1% and projecting through plates Tl and 76 secured to the side edges of the iron ing. board 36.

Thus it will be seen that by rotating the key 60, the

locking bolts

70 and 72 may be si nultaneously projected or withdrawn.

For normally yieldingly holding'the parts in their position with the locking bolts projecting, I provide a spring 7 8, such as that shown for instance in Figure ,9.

When the ironing board is in its folded up position, the-outer ends of the bolts 70 and 7 2 project into the channels 18, in which these bolts may slide up and down.

In the upper end [of the door member 30 is mounted a locking device, which is similar, except that in some instances, the spring 7 8 is omitted. The lockingbol'ts' o'fthislatter locking device coact with the holes 2 1; (Figure 2) for locking the doors in their case closing position.

Secured to the side jambs 11 rearwardly from the channels 18'are upright members 80, each having a series-of notches 82. When it is desired to move the parts ,fi'onrthei-r positions shown in Figure 3 to position where the ironing board is ready for use" as shown in Figure 1, the operator manipulates the locking device at the upper end of thedoor member 30, which for convenience ofref'crence is indicated by the reference numeral C for withdrawing the bolts of such locking device from the holes 24. I I

The two door members and the ironing board are then swung on the

lower locking bolts

70 and 72 .as pivots downwardly and outwardly to theposition shown in Figure-4.

The door member 30' is then swung clownwardly away from the ironing board to'the position shown for instance in Figure 5 until it rests on the floor. Then the lower end of the ironing board is slid upwardly from its position shown in Figure 5* to its position shown in Figure 6 movement, the lower locking bolts 7 O and 72 slide in the channels 18. v

The spring 78 tends to yieldingly force the bolts outwardly to thus keep them projected into the channels 18 and to cause them to enter the lower holes 20. Itwil-l be, understood, of course, thatthe key 6Q may be manipulated for controlling the bolts for causing them to enter the holes 20. at any desired height.- After. the bolts havebeen projected into-the holes 20, the spring'78 prevents any accidental IGHIOVtLlOf the bolts from the holes.

Itwill be'noted that the spline-42m cut away for a portion of its length adjacent to 'the passage 44' as at l2 on one side of the hole 4:6, whereas the material oftliebo'ard itself is cut away along the passage 44 on the other side of the hole 46 as indicatedat-36.

During such sliding vllU - other direction is limited by engagement of the bolts 70 and 7 2 with the walls of the passage 44. When the bolts are thus extended a :case when the-device is folded up serve: to

and are received in the proper holes the door, member 32 is then swung toward the case and its lower edge is inserted into an opposite pair of notches 82 (see Figures 1 and 8). 1

It will be seen that this operation requires that the locking bolts in the door member be withdrawn while the door member 30 is being adjusted to the proper notches 82. The locking bolts are then projected into the channel 18. When this is done, the door member 30 will be rigidly locked in its position shown in Figures 1 and 8, and the ironing board will be rigidly held for use.

The operations necessary for returning the ironing board and the door members to the position shown in Figure 3 will be obvious.-

I preferably provide a detachable or demountable sleeve board for use with my ironing board construction. This consists of a sleeve board proper 84. One end of this sleeve board has a frame consisting of the transverse member86 extending across the end of the board to the opposite side jambs 11,

and is provided with the portions 88 extend ing at right angles to it, as shown in Figure 1. From the portions 88, frame members or portions are inclined to the side edges of the board 84 and secured thereto as at 92.

The sleeve board 84 has a locking device 1) similar to the first locking device hereinbefore described.

The locking

bolts

70 and 72 of the locking device D project away from the board 84 and through the frame portions 88 as shown in Figure 1.

By letting these last-named

locking bolts

70 and 72 project into the holes 26 (Figurel), the sleeve board may be hung as shown in Figure 2.

Secured to the sleeve board 84 spaced from the ends thereof by pivotal connections are th arms 94 of a supporting bail 96.

\Vhen it is desired to use the sleeve board I,

with the ironing board, the locking device D i manipulated to withdraw its locking bolts from the holes 26, and these locking bolts are then selectively inserted into the desired holes 28 (Figure 2). The bail 96 is dropped to rest on the ironing board 36 as shown in Figure 1, and the sleeve board is ready for use.

An ironing board structure of the kind referred to herein has a large number of advantages, some of which will be readily inferred from the statement of the objects and the description of the device.

It will be seen that an ironing board structure'of this kind can'be manufactured and then shipped and installed as a unit between studding in a wall, and willhave the appear- There are no,

ance of a closet or cabinet. parts which project into theroom when the ironing board isfolded up. I

The door members which serve to close the strengthen and support the ironing board when it ,isin position-for use.- They eliminate the necessity for having hinged doors on the case, Which might be in the way for ironing operations or interfere withthe use of the room when the lroning board is up.- V An-lromng board of satisfactory length can be employed because the case stands oloserto the floor, and can be put in any room of or dinary height. The ironing board is quickly and easily adjusted to any of its'various positions and is rigidly supported in its position for use.

In making such adjustment, there is a considerable advantage in having the lower end of the ironing boardtrunnioned in such'manner that it travels freely in the grooves in the j ambs and in providing trunnioning means,

which-will serve as locking means for holding this lower end of the board in itsfraised position; The board might be held and supported in the position shown in Figure g6,if

it were desired for-any reason toileave it so. It1s preferable, however, to arrange the member 32 as shown in Figure 1,-thus leaving the space under the board as'nearly free as possible and locking the member 32 against accidental displacement. The whole casing and lronlng-board structure herein shown may .be arranged to serve as a broom case, if that is desired.

It willbe of course understood that sdnie, i;

changes may be made in thedetailsof the construction andarrangement of the parts of my improved ironing board structure without departing" from the spirit'and purposeof my invention', and it is my intention;to cover L; by my claims, any modified formsofstruc- .t'ure or use of mechanical equivalents which be reasonably included within the spirit .of my invention and the scope of my claims.
