4 Claims. (Cl. 38-121) This invention relates generally to ironing boards or tables, but has reference more particularly to an ironing board or table which is adjustable in height.

A primary object of the invention is to provide an ironing table or board of the character described which can be easily and quickly adjusted to various heights, so as to accommodate it to use by persons of different heights, or to render it usable by a person who is seated.

Another object of the invention is to provide an ironing table or board of the character described, which can be easily and quickly folded to a closed compact condition, facilitating storage thereof in a relatively small space.

A further object of the invention is to provide an ironing table or board of the character described having incorporated therein a novel mechanism for latching or locking the table top in adjusted position, and which mechanism is extremely simple in construction, and easy to install or assemble with the table.

Other objects and advantages of my invention will be apparent during the course of the following description. In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a side elevational view of the ironing table;

Fig. 2 is a top plan view of the table, with portions of the top broken away to better illustrate certain features of construction;

Fig. 3 is a fragmentary longitudinal cross-sectional view, taken on the line 33 of Fig. 2, and

Fig. 4 is a fragmentary transverse cross-sectional view, taken on the line 44 of Fig. 3.

Referring more particularly to the drawings, reference character 1 designates generally a framework comprising a pair of longitudinally-extended

frame members

2 and 3 respectively. These

frame members

2 and 3 are parallel with each other for the greater part of their length, are bent as at 4 to provide inwardly-tapering portions 5 and 6 respectively, and are bent as at 7 to provide

arcuate portions

8 and 9 respectively, which are joined, as at 10, by welding. The

frame members

2 and 3 are also bent as at 11 to provide

straight portions

12 and 13 respectively, which are joined, as at 14, by means of an angle plate 15, which is spot welded to the inner faces of the

portions

12 and 13, and extends across the joint 14. The

frame members

2 and 3 are preferably formed from metal strip of channel or U-shape cross-section, the web 16 of the strip being disposed in a vertical plane, and the

flanges

17 and 18 of the strip being disposed in horizontal planes.

The frame members are provided with inwardly extending embossments 16a which extend along the webs 16 across the bends 4, and which serve to provide reinforcement against downward bending of the

portions

5, 6, 8 and 9 relatively to the

portions

2 and 3 of the frame members.

Secured to the lower faces of the flanges 17 of the

frame members

2 and 3, as by spot welding, is a perforate metallic top 19, preferably formed from expanded metal having substantially diamond-shaped apertures, with the long dimension of the diamonds preferably extending lengthwise of the top 19.

The top 19 is also supported at various points intermediate its ends by transverse supporting

frame members

20, 21. 22, 23 and 24. These frame members extend substantially to the webs 16 of the

frame members

2 and 3. The members 20 and 24 are in the form of inverted channels, relatively shallow in depth, with the webs of these channels spot welded to the lower faces of the Patented Nov. 9, 1954 flanges 17 of the

frame members

2 and 3. The

frame members

21, 22 and 23 are generally U-shaped in crosssection, with the web portions 25 thereof spot welded to the upper faces of the flanges 18 of the

frame members

2 and 3, and are provided with

horizontal flanges

26 and 27 which are spot welded to the lower faces of the flanges 17 of the

frame members

2 and 3.

In order to maintain the top 19 substantially flat throughout, the top is spot welded at suitably spaced points to the webs of the channels 20 and 24 and to the

flanges

26 and 27 of the

frame members

21, 22 and 23.

An additional transverse frame member 28 is provided between the members 23 and 24, the member 28 being in the form of a channel of relatively shallow depth, the web of which is spot welded to the upper faces of the flanges 18 of the

frame members

2 and 3.

Secured, as by welding, to the lower face of the web of the frame member 20 is a pair of transversely spaced

brackets

29 and 30, provided with downwardly extending

ears

31 and 32 respectively. These ears provide hearings in which a shaft 33 is journalled. Secured to the ends of this shaft is a supporting leg

unit comprising legs

34 and 35 which are retained against displacement from the shaft by 'means of nuts 36.

The

legs

34 and 35 are formed from tubular stock, and are bent as at 37 to provide inwardly tapering

portions

38 and 39 respectively, are bent as at 40 to provide

straight portions

41 and 42 respectively, which are parallel with each other, and are bent as at 43 to provide outwardly tapering

portions

44 and 440 respectively, to the lower ends of which rubber crutch tips 44b or the like are secured.

Secured, as by welding, to the web portions 25 of the

frame members

22 and 23, isa U-shaped member 45 which extends longitudinally of the ironing table. This member 45 serves as a spacer to maintain, in spaced relation to the table top, a guide member 46. The guide member 46 is of inverted U-shaped form, having a web 47 which is welded to the web of the member- 45, laterallyspaced downwardly-extending

sides

48 and 49, and

flanges

50 and 51 extending parallel to the web 47.

The

sides

48 and 49 of the guide member are provided with longitudinal openings 52, in which a shaft 53 is guided for movement, these openings 52 having unobstructing upper and lower guide edges or surfaces. The web 47 of the guide member has stamped therefrom a series of longitudinally-spaced detents or lugs 54, which extend downwardly and are curved to receive and form stops for the shaft 53.

The shaft 53 has pivotally connected to its ends a second supporting leg

unit comprising legs

55 and 56 which are retained against displacement from the shaft 53 by means of nuts 57.

The

legs

55 and 56 are formed from tubular stock, and are bent as at 58 to provide outwardly tapering

portions

59 and 60 respectively, and are bent as at 61 to provide

straight portions

62 and 63 respectively, which are parallel with each other, and to the lower ends of which rubber crutch tips 65 or the like are secured.

A U-shaped strap is also provided, consisting of a bottom portion 66, upstanding arms 67 and 68,

horizontal portions

69 and 70, which extend outwardly from the upper ends of the arms 67 and 68 respectively, and downwardly extending flanges 71 and 72 which extend from the outer ends of the

portions

69 and 70 respectively. The shaft 53 extends through the arms 67 and 68 and through the flanges 71 and 72 of the strap. The arms 67 and 68 of the strap function to resist spreading apart of the

sides

48 and 49 of the guide member, while the arms 67 and 68,

portions

69 and 70, and flanges 71 and 72 function to maintain the upper ends of the

legs

55 and 56 in properly spaced relation to the

sides

48 and 49 of the guide member 46. r

The leg units are pivoted to each other, as by means of a pivot pin 73 which extends through the units at a point intermediate their lengths. The

legs

34 and 35 of one leg unit being maintained in spaced relation by means of a sleeve 74 mounted on the pin 73, and the legs 55 and S6 of the other leg unit being maintained in spaced relation to the

legs

34 and 35 by means of washers 75 mounted on the pin 73. Nuts 76 secured to the ends of the pin 73 maintain the

legs

55 and 56 against displacement from the pin.

The lower ends of the

legs

34 and 35 are maintained in spaced relation by means of a spacer sleeve 77, which is mounted on a pin 78 extending through these legs, the legs being maintained against displacement from this pin by means of nuts 79 secured to the ends of the pin. The lower ends of the

legs

55 and 56 are maintained in spaced relation by means of a spacer sleeve 80, which is mounted on a pin 81 extending through these legs, the legs being maintained against displacement from this pin by means of nuts 82 secured to the ends of the pin.

The guide member 46 guides the guided member or shaft 53 in the movement of the leg units from open to closed position, and vice versa. The shaft 53 may be stopped at a plurality of positions intermediate the open and closed position of the leg units, in order to adjust or vary the height of the ironing table, the number of such positions corresponding to the number of detents or legs 54 For this purpose, the narrow end of the table is lifted, while the foot of the operator bears down on the spacer sleeve 77 to hold the leg units steady, thereby disengaging the detent or lug 54 from the shaft 53. The top is then I raised or lowered to the desired elevation, the leg units moving relatively to each other about their pivotal connection during such raising of lowering, and when the desired elevation has been attained, the narrow end of the table top is lowered to cause the shaft 53 to enter the detent or lug 54 which is most closely adjacent to the shaft, thereby locking the table in its adjusted position, since the shaft 53 cannot pass beyond the detent or lug 54 which it has entered.

In Fig. 1, two positions of adjustment in height of the 1 table top are shown, one in solid lines and one in broken lines. In order to permit the leg units to be moved to a closed position in which they lie parallel with and closely adjacent the lower surface of the table top, the distance between the axis of the shaft 33 and the extreme left end of the openings 52 (as viewed in Fig. 1) is at least as great as the sum of the distance between the axes of the shaft 33 and pin 73 and the distance between the axes of pin 73 and shaft 53.

Moreover, the leg unit comprising the

legs

34 and 35 is nestable Within the leg unit comprising the

legs

55 and 56, so that when the leg units are folded to a closed position, they lie in substantially a single plane, parallel with and closely adjacent the table top.

It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to, without departing from the spirit of my invention, or the scope of the subjoined claims.
