16 Claims.

The present invention relates to an ironing board or like structure, of the collapsible type.

An object of the invention is to provide a collapsible ironing board or the like with an improved arrangement of constituents whereby the leg and brace structure may easily and conveniently be disposed in latched extended and collapsed positions.

Another object of the invention is to provide a latch means for the leg and brace structure which is so formed and located as to be actuated without effort additional to that required for extending or setting up the leg and brace structure. Another object of the invention is to provide a device of the character stated with a single latch element that performs the dual function of latching the leg and brace structure in both the extended and collapsed positions.

A further object of the'invention is to provide latching means which, in addition to the latching function, provide bracing means for other parts of the structure.

.The foregoing and other objects are attained by the means described herein and disclosed in' the accompanying drawing, in which:

Fig. 1 is a bottom perspective View of the improved device of the invention. v

Fig. 2 is a perspective view of a tension rod guide and stop which forms a detail of the invention.

Fig. 3 is a fragmental cross-sectional view taken on the Fig. 1 view through the handle 5, showing the latch element 6 in elevation.

Fig. 4 is a plan view of the latch element 6, as

seen from the line 4-4.

The improved device includes the conventional table member I which has a front end B, a rear end 9 and an under surface It). Adjacent to the rear end of the table member there is fixed a bracket means 2 to which are pivoted at [3 and M the pair of rear legs l5 and I6, respectively. As is evident, the rear leg structure, is adapted to be moved from the operative or extended position shown in Fig. 1 to a position flat against the under surface of the board or table member,

in accordance with common practice.

The movement of the rear leg structure to the twc positions mentioned, may be accomplished by swinging the handle 5 through an arc of a circle,

the center of which circle is at the axis of the pivots ll and- E8 of a rear leg bracing means. The rear leg bracing means comprises a pair of toggle brace bars l9 and 2!] which have corresponding rear ends pivoted, as at 2| and 22, upon the rear 1egs l5 and. 16, respectively. At the pivot points 23 located near the upper ends of the toggle or brace bars, are pivoted the

shorter toggle bars

24 and 25, said. bars being movable through a circle arc of which the common axis of pivots I? and I8 is a center. The pivots I! and I 8 may 5 be mounted upon the table member in any suitable manner, such as by means of a bracket element 26. From the foregoing, it will be understood that movement of the handle 5 through the circle are as stated, will either extend the rear leg 10 structure tothe position of Fig. 1, or collapse it to a position at which the

legs

15 and 15 are disposed substantially in parallelism with the plane of the table member.

If desired, the rear legs may have associated therewith a means for spreading the legs apart as the legs are moved to the operative or extended position. Said means may comprise a pair of

cross braces

21 and 28 having upper ends pivoted as at 29 and. 39, upon the rear legs at a 20 location near the rear leg pivots l3 and. M. The lower ends of the cross braces may be bent at an angle as at 3| and perforated to receive pivots 32 on thebraces l9 and 20, which pivots are spaced from the pivots 2| and 22 that connect 25 the braces l9 and 20 to their respective rear legs. The spacing between the adjacent pivots 2l--32 and 22-32 results in a compressive action upon the cross bars when the rear legs are extended to the operative position, but the rigidity of the 30.

cross bars enforces an outward movement of the legs away from one another when the legs are extended to the Fig. 1 position. It is to be understood that any other suitable means may be substituted for those disclosed herein, for effecting 35.

an automatic spreading action of the rear legs, the disclosure hereof showing but one form of several means for the purpose.

A front leg structure 33 is associated with the table member for supporting the front end there- 40 of, which structure may comprise a pair of leg members 34 and 35 connected together at one end 36 and spaced apart at the opposite or upper end so as to be pivoted at 31 and 38 upon a'b-racket 39 fixed to the under surface of the table member. 45 The upper end of each leg preferably is tapered or mitered as indicated at 40, to abut the under surface of the table member and limit movement of the front leg structure in a clock-wise direction of rotation about the pivots 31 and 38. Movement of the structure'in the opposite direction may be limited, when the board is set up for use, by a pair of tension rods or the like 4| and 42 the forward ends 43 of which are suitably pivoted relative to the lower or forward end of the front 5 leg structure, while the rear ends of said rods are headed at 44 to abut stops or brackets 45 carried by the lower ends of the toggle or brace bars l9 and 20. Each of the brackets 45 is perforated as at 46 to permit sliding movement of the tension rods relative to the brackets, upon movement of the leg structures to and from the extended position. It is to be understood that the rods 4|. and 42 will be tensioned when the toggle structure l9-20--2425 is disposed in the Fig. 1 position, in accordance with common practice.

Means are provided for latching the leg structures in both the extended and collapsed positions. Said means comprises a single latch element 6 secured by means of rivets, screws or other fasteners 41 to the under surface of the-table member. The latch may be of any approved or suitable construction, there being shown a preferable form in which there is a depending plate 48 bent slightly forwardly at 49, said plate having extensions or lugs 50 adapted to support a pivot A-movable latch .piece52 carries cooperative perforated lugs. 53. through which extend the pivot 5| so that the movable part 52 may have a slight rocking or rotating movement about said pivot. One end' 54 of the -movable part 52' is developed into'a hook inclined upwardly asshown, toengage the portion 49 of plate 48, while the opposite end of the movable memberis formed to provide a thumb piece or trip 55 to be'manually actuated for moving the member 52in a clockwise direction of rotationabout the pivot 5|. The movable memberzmay advantageouslybetreturned to the normal position indicated by means of a coiled spring 56.

Attention is directed'to the'fact that the trip portion 55 for the latch element is disposed closely adjacentto the handle 5 when the device is set upforuse, so thatone hand of the operator may manipulate both the latch'element' and, the actuating handle 5.

The single latch element above. described. is adapted to engage and hold either: one: of two latch'pieces'58 and 59, the latchypiece 58 being 3 carried by the toggle structure,.and preferably by the shorter toggle bars 24 and'25i The-latch piece 58 .not"only provides a; means for latching the toggle structure in the operative position, but it also bracesiand" strengthens thatportion of the toggle structure which comprises the

members

5,23, 24 and 25. It is. believed readily evident that the structure'may be collapsed by means of a single operation which consists of depressing the-trip member 55- with the thumb while at the same time, and with the same hand, the operator: may swing the handle 5 downwardly and for-- wardly through a circle are about the pivots Upon moving the toggle structure toward the inoperative or collapsed position just'mentioned, the front leg structure 33' will be elevated toward the collapsed position by reason of contact with the

brace members

21 and 28, thereby to advance the second latch piece 58 toward the latch element and into the latching position previously occupied by the first latch piece 585 The. front leg structure thereby will be held substantially against the undersurface' of thetable'member, in substantial parallelism with the plane thereof,

- while at the same time the said front leg structure'will abut the handle 5 and securely hold it against the under surface of the table member at a location near the point indicated at X. It is therefore evident that the latching of the front leg structure in the collapsed'position, serves to hold both the front leg structure and the rear leg structure in a completely collapsed condition against the under surface of the table member. The ironing board, therefore, may be moved about, stored or carried without a possibility of accidental release of the leg structures. Moreover, the improved device may be stored in a smaller space than heretofore.

The end 54 of the movable latching element 52 may be inclined as shown, or not, as desired, but by using proper inclination the latch pieces 53'and 59 will automatically assume a latched position behind the inclined end.

The perforation B0 in the bracket of Fig. 2 is merely for the purpose of receiving a rivet or other fastener El as disclosed in Fig. 1.
