IRONING BOARD SUPPORT Filed Oct.- 25, 1939 f ATTORNEY.`
Patented Apr. 1, 1941 OFFICE IRONING BOARD SUPPORT William A. Noack, Los Angeles, Calif.
Application October 25, 1939, Serial No. 301,206
This invention relates to an ironing board support, and more particularly to means for guiding and stabilizing certain movable parts of the means for supporting an ironing board.
An object of the invention is to simplify the construction and reduce the number of parts required in an ironing board support, while still maintaining sturdiness of construction and reliability of operation.
A more specic object of the invention is to provide improved means for guiding the movements of a swingable shelf or platform upon which the ironing board is turnably supported.
The invention includes the provision of an improved spider construction of the aforesaid swingable shelf whereby lightness, strength, and low cost of manufacture are secured without impairing the functioning of the device, added strength being afforded to said spider construction by so shaping and positioning certain of its arms as to produce a superior trussing effect.
Other objects, advantages and features of invention will hereinafter appear.
Referring to the accompanying drawing, which illustrates .a preferred embodiment of the invention,
Fig. 1 is a side elevation of the device in its operative position, the door being omitted to expose interior construction, taken in part section on line I-I of Fig. 2.
Fig. 2 is a fragmental plan view of Figure 1.
Fig. 3 isa front elevation of the device in its up-swung position.
Fig. 4 is a sectional, fragmental detail illustrating the ironing board pad and cover.
Fig. 5 is a sectional detail of an additional bearing means for the shelf or bracket which supports the ironing board proper.
Fig. 6 is a fragmental detail in which is reproduced, in a modified form, a portion of the structure shown in Fig. 3.
Referring in detail to the drawing, the casing I is of an upstanding character, being rectangular and of the proper dimensions to house within it an ironing board II which is pivotally secured at I2, in a flatwise manner, to the midwidth portion of a swingable skeletal shelf or spider I3. Said casing may be built into the wall of a building, or otherwise stabilized in its upstanding position.
Said swingable skeletal shelf I3 has at opposite sides of its lower end trunnions I which enter bearing seats I6 formed in inner faces of the side pieces I1 carried by the back I4 of the casing. With said shelf I3 cooperates the U-shaped supporting rod IB'having at each extremity an outwardly directed end portion I9 which pivotally engages a seat or bore 2 I in the lower portions of the side pieces I1 of the casing.
Said skeletal shelf I3 has a rectangular rim member extending along its two long sides and across its ends, said rim member having side runs 22, an end run 23 across the free end of the swingable shelf and an end portion 24 which spans the distance between the'trunnions I5 of the shelf.
The spider structure of the shelf I3 has a pair of radial arms 21 in a v-relation to each other and opposite to said arms 21, a pair of shorter radiating arms 28. All these arms radiate from the hub portion 3| through which the pivot I2 extends.
The arms 28 lie in substantially the same plane as the rim portion of the spider frame, but the arms 21 are in a parallel relation to said rim, being spaced away therefrom the proper distance to providel a clearance within which the central cross portion I8a of the U-rcd moves with a working t.
'I'he outer end portions of the arms 21 have deflected end portions 29 whereby they are united integrally with the corners of the aforesaid rim at the free end of the frame, While their inner ends are likewise united integrally to the opposite sides of the hub 3i by deflected end portions 30. The inner sides of said arm portions 29 and y 3U form stops which limit the movement of the cross bar portion I8a of the U-bar I8. the arms 21 being parallel to and sufficiently spaced away from the plane occupied by the side runs 22 of the spider to afford the proper working space for said portion I8a of the U-rod. Owing to the fact that, when the spider structure is viewed in plan, the arms 21 and 28 appear as extending substantially straight from the hub from which they radiate to the rim corners which they join, a superior bracing effect is secured in the spider structure while maintaining minimum weight.
In the right hand portion of Fig. 5 is shown a circular spacer member 4B bolted to the building wall 4I and having a central projection 42 within which is formed a bearing recess 43 to receive one of the trunnions I5, said trunnions turnably projecting through the side walls of the casing.
Of the four arms which have been described, all of which radiate from the hub portion of the spider, the paired arms 28 are the shorter and they join each other and the hub at a more obtuse angle than that between the arms 21. Said arms 28 may be made of a sufficiently sturdy character to make it possible safely to dispense with the rim run 24 which extends across that end portion of the spider like shelf which is adjacent to them.
The pairs of arms 21 and 2B combine to form an approximately cruciate bracing means for the rim portion of the swingable shelf, so that said shelf may be subjected to hard usage without danger of breaking.
To prepare the device for use the ironing board II together with the shelf I3 will rst be swung down from the vertical position shown in Fig. 3V
to the horizontal position shown in Figs. 1 and 2, and then the ironing board will be swung to one side or the other in the usual manner to economize space while being used.
A winged clamping nut 32 is shown screwed on to the pivot bolt I2 to clamp the ironing board proper in its adjusted position in relation to the shelf I3.
Owing to the fact that the stop elements 2S at the outer ends of the arms 2l' are widely spaced apart, they cooperate with the U-rod I8 to brace the ironing board support in a stable manner when said ironing board is in its down position. The arm portions 30 which join the hub are considerably closer together than the arm parts 2S, but no disadvantage results from this fact because no bracing of the ironing board support is required when it is in the folded up position and hence the central portion I8a of the U-rod may be contracted to remain out of contact with the aforesaid arm parts 30 at all times.
Each of the corner portions of the anchored end of the swingable spider frame I3 carries an L-shaped clamping bolt 45 the short limb 46 of which is clamped down upon the arcuate inner end ila of the ironing board I I. Nuts 41 screw on to said bolts to perform this clamping operation. Said bolts have squared shanks 48 to prevent them from turning from their proper operative positions.
Along the under side of the edge portion of the ironing board II extends a groove 50 which affords room for fastening the downwardly directed edge portion 5I of a cloth 52 without said cloth extending below the lower face of the ironing board, which is to be avoided in order not to interfere with the swinging movement of the board in relation to the upper face of the shelf I3.
The usual pad 53 underlies the cloth 52.
In situations where the ironing board is not to be subjected to unusual strain, or required to support excessive weight, the structure shown in Fig. 6 may be used to advantage, the omission of the bar 24 lightening the weight of the skeletal shelf which supports the board and lessening the cost of manufacture.
1. In an ironing board structure, a support, an ironing board supporting frame having a free end and opposite thereto an end portion pivotally anchored to said support, said frame having an approximately rectangular rim, all parts of said rim occupying substantially the same plane, two pairs of bracing arms within said rim radiating from a common hub, the outer end of each of said arms being united to a corner of said rim, there being a pair of said radiating arms in each end portion of said frame, each arm being substantially straight in plan, from said hub to its juncture with said rim, one pair of said arms lying in a plane which is in a parallel relation to the rim of said frame and is offset therefrom to the proper distance to provide a Working clearance for a swingable brace bar, and the other pair of said arms lying in the same plane as said rim, said arms which are oiset from the plane of said rim having end portions which unite them to corner portions of said rim at the free end of said frame.
2. In an ironing board structure of the kind described, a main support, and an ironing board supporting member mounted thereon comprising a swingable spider frame having an approximately rectangular rim and having an end portion pivotally anchored to said support and radiating arms within said rim having a common hub at their inner ends and having their outer ends united to the corners of said rim, there being a pair of said radiating arms located in each end portion of said spider frame, one pair of said arms lying in a plane which is in a parallel relation to the rim of said frame and is offset therefrom to the proper distance to provide a working clearance for a swingable brace bar, and the other pair of said armslying in the same plane as said rim, said arms which are olset from the plane of said rim having end portions which unite them to corner portions of said rim at the free end of said frame, the anchored end of said swingable frame being open and the pair of radiating arms adjacent thereto joining `each other at a more obtuse angle than the angle between the arms of the other pair.
