IRON ING BOARD Filed Oct. 22, 1965 2 Sheets-Sheet 2 l N VENTORJ FRA NKL IN D. MFA TH y JOHN L.DOYLE B d oohM ATTORNEYJ United States Patent s,29s,s2s IRONING noARD Franklin D. Meath, St. Paul, and John L. Doyle, Minne- This invention relates generally to space saving housekeeping apparatus and more specifically to a portable collapsing ironing board, which may be compressed vertically and horizontally to present a compact package for convenient storage in a small area and also, in its open con figuration, a sturdy platform for ironing.

Ironing boards are commonplace in the home and are used to provide a work surface for pressing clothes and other fabrics with a hot iron. There are present in the art folding ironing boards which fold into a flat unit which can then be set up against a wall or placed in a closet. The problem with this type of board as stored, is that it is usually placed in such a position in the closet so that when the closet door is opened it is the first thing to fall out, or the slightest jar will tip it over. This invention is directed to the elimination of this problem and presents a board which provides a sturdy ironing table and a folding work surface which may be substantially reduced in overall dimension. The present unit can also be collapsed vertically to present substantially smaller vertical dimension than'that maintained during use. The portable ironing boardof the present invention is also provided with small vertical adjustments to accommodate users of various sizes.

Another problem, present in the prior art devices, is the question as to what is to be done with the hot clothes iron after use. Many home fires are started by careless placement of the hot clothes iron following use. Innumerable burns have resulted from a housewife leaving the hot iron in a place where it is not expected to be. To eliminate this problem, the present invention provides a heat resistant storage compartment or box in which the hot iron'may be placed after use without the necessity of waiting for it to cool. The storage box provided may also be'used for other articles which are used in connection with ironing.

I 3,298,325 Patented Jan. 17, 1967 In the drawing, 10 is a base which is adapted to give sturdy support on a flat surface such as the floor. A vertical leg or standard 11 is rigidly secured to base 10.

Standard 11 is provided with at least one telescopic joint, and preferably two as are indicated at 12 and 13. Each of the

telescopic joints

12 and 13 are identical and only one will be described; in this case, the telescopic joint 12. Telescopic joint 12 has both a female joint member 14 and a male joint member 15. It is necessary to provide some means for locking the male joint member 15 relative to the female joint member 14. To this end, several longitudinally spaced apart holes 16 are provided in male joint member 15. Holes 16 cooperate with other locking means described below to lock telescopic joint 12.

It is necessary that male joint member 15 not be allowed to rotate relative to female joint member 14 so that holes 16 always remain in the same line. To this end, male member 15 is provided with a longitudinal indent 17 which acts as a track. A follower, shown as a pin 18, is secured to female joint 14 to engage indent 17 and prevent relative rotation between male joint member 15 and female joint member 14. Additional male joint members, as 19, are for the sake of manufacturing economy, provided with a longitudinal indent 20. Indent 20 has such dimensions as will allow indent 17 to engage indent 20 as pin 18 does relative to indent 17 to hold male joint member 19 against rotation.

To lock telescopic joint 12 against vertical movement, a locking means 21 is provided. One convenient locking means 21 is comprised of an elongated elastic member or lever 22 which is secured longitudinally to female joint member 14. One means for securing lever 22 to female joint member 14 is demonstrated by the use of the rivet 23. Lever 22 is shown as being provided with finger grooves 24 to provide a ready grip. A fulcrum 25 is secured to lever 22 between the mid-point and the free end of lever 22. To keep lever 22 in longitudinal alignment with female joint member 14, a rivet 26 is placed through fulcrum 25. Rivet 26 is of a length greater than the thickness of fulcrum 25 and permits lever 22 to move freely along rivet 26. A sturdy weight bearing pin'27 is rigidly secured to the free end of lever 22. A hole 28 is provided in female joint member 14 in alignment with the line of holes 16. Pin 27 is of a dimension which will easily pass through hole 28 and engage hole 16 but sturdy enough to withstand the shear force imposed upon it by weight above. FIGURE 3 depicts pin 27 in position bearing the weight of male joint member 15 and all weight that that member carries.

To release telescopic joint 12, it is necessary first to manually raise male joint member 15 slightly to remove the weight from pin 27. Lever 22 is then pressed at finger grooves 24. Pin 27 thus, is withdrawn from hole 16 allowing male joint member 15 to be moved vertically relative female joint member 14. Thus, male telescopic joint member 15 may be raised or lowered until the next hole 16 is in alignment with hole 28, or for a substantial movement, passing several holes 16 depending on whether the unit is being collapsed for storage or whether it is being adjusted to accommodate a taller or shorter user of the board.

Telescopic joint member 13 has similar locking means 21 which it is not necessary to again describe.

At the top of standard 11 an elongated table 29 is provided. Elongated table 29 is adapted to fold along at east one trans-verse line. Preferably, for the sake of compactness and convenience, two fol-ding lines are provided resulting in two

end sections

32 and 33, and a mid dle section 34. Since pressures will always be placed on the top of board 29 in use, it is desirable from a manufacturing point of view, to have the

ends

32 and 33 only fold upwardly and then back down onto the center section 34 to provide a horizontally small unit. End 22 is conveniently pivoted about a conventional piano hinge 35, while end 33 is shown pivoted about a similar piano hinge 36.

Piano hinges

35 and 36 are desirably located near the top surface of elongated table 29 to provide only upward pivoting of

ends

32 and 33. Downward move ment of

ends

32 and 33 is conveniently limited, as will be seen in FIGURES l, 6 and 8, by the

flanges

37 and 39 on

ends

32 and 33, respectively abutting flanges 38 of center section 34.

End 33 is for-med with

sides

40 and 41 tapered to accommodate pant legs, etc. Sometimes, as for example when bed sheets or other large flat work are to be pressed, it is desirable to have a full rectangular shape for the elongated table 29. To this end,

table extensions

42 and 43 are provided.

Table extensions

42 and 43 are pivotally secured to end section 33 so that when elongated table 29 is in an open

position table extensions

42 and 43 pivot about a vertical axis. One convenient Way of providing such pivoting is by loosely fastening table extension 42 to end member 33 by a rivet 44 and similarly loosely fastening table extension 43 by a rivet 45.

Table extensions

42 and 43 are further supported by the slots 46 and 47 through which they respectively pass through

sides

40 and 41. In normal operation,

table extensions

42 and 43 would be the position depicted in FIGURE 6 where

flanges

48 and 49 are abutting

sides

40 and 41, respectively.

To control the movement of

table extensions

42 and 43, a wheel 50 is rotatably secured to the bototm of end 33, as by the bolt 51. Bolt 51 passes through end 33 and the spacer 52 is used to hold wheel 50 away from end 33. Bolt 51 is retained by nut 53. Nut 53 is limited so that it cannot be tightened so much as .to bind wheel 50. To facilitate rotation of wheel 54} a handle 54 is provided secured to that member. A link 55 is pivotally secured to wheel 50, as by the loose fitting rivet 56 and to table extension 42 as by loose fitting rivet 57. Link 58 is pivotally secured to wheel 50 as by loose fitting rivet 59 and to tableextension 43 as by loose fitting rivet 6%). It will be noted, in FIGURES 6 and 7, that as wheel 50 is rotated counterclockwise, link 55 forces table extension 42 outward from side 38 and link 58 forces table extension 43 outward from side 41. When

table extensions

42 and 43 are in the maximum outward position, depicted in FIG- URE 7, links 55 and 58 are in line with the center of wheel 53. Thus, forces tending

to'push table extensions

42 and 43 inward are transmitted across the center of wheel 50. A locking relation is thus established and

table extensions

42 and 43 are held out until wheel 53 is moved off dead center.

For further convenience a storage compartment or box 61 is secured to the bottom of center section 34. Box 61 should be desirably made of a heat resistant material which can stand up to the placing of a hot clothes iron inside without the necessity of first letting it cool.

To use the ironing board of this invention, one would have it generally in a position depicted in FIGURE 1. A vertical adjustment may be made by unlocking one of the

telescopic joints

12 or 13 and raising or lowering it to the appropriate level for the user then reinserting the weight bearing pin 27 into a hole 16. When finished ironing, the user first places the iron in box 61, then unlocks both

telescopic joints

12 and 13, reducing standard 11 to its minimum dimension by allowing it to collapse. Ends 32 and 33 are then folded up and over, onto center section 34. This results in a package which is small enough to be conveniently stored in small areas without fear of it flopping over at the slightest provocation.
