IRON ING TABLE.

Application filed January This invention relates to improvements in folding ironing tables, and particularly to improvements in the collapsible support shown in our Patent No. 1,450,986, dated April 10,1923.

The main objects of this invention are to provide a table in which the legs spread sufficiently to provide stable support and may be folded entirely within the outline of the board or top member; to provide such a table which may be folded or unfolded by simply moving one member thereof; to improve the rigidity of the support; and to provide improved means for spreading the rear pair 1 of legs in the extended position.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which:

Figure 1 is a side elevation of the ironing stand when set up.

Fig. 2 is a plan view of the same, showing by dotted lines some of the parts below.

Fig. 3 is a rear elevation looking towards the left of Fig. 1.

A Fig. 4 is a bottom view of the stand when collapsed.

Fig. 5 is a section of the line 5-5 of Fig. 1. F'Fig. 6 is a section on the line 66 of Fig. 7 is a section on the line 7 of Fig. 2. r

In the form shown, the rear legs are pivoted to swing outwardly in a yoke which is pivoted to the ironing board, so that the rear legs may be folded against the board and entirely under the same. A toggle linkage is provided for spreading the lower ends of said legs and links are connected to each leg nearthe upper end and hooked into slots in the yoke which limit the spread of the legs in such manner that the toggle linkage is locked by resilient pressure of the legs when the stand isin the extended position. The hinged brace for opening the rear pair of support members is pivotally connected to the toggle linkage, andalso to the ironing board.

Referring to the drawings, a board or top member 1 is provided with a pair of rear legs 2. A single sloping and forwardly extending leg 3 is pivotally connected to the board, and a centrally hinged or toggled brace 4 is pivoted to the bracket 5 on the ton and pivotally connected to the central link 6 55 of the toggle linkage, which comprises the link 6 andthe side links 7 which are each 5, 1926. Serial No. 79,344.

pivoted to the ends of the central link 6 and pivotally connected to the respective legs 2. The central link 6 is provided with lugs or stops 8 which overhang the upper edges of the bars 7 to limit the movement of the togglebeyond its dead center or straightened posltion.

The spread of the legs 2 is limited by the braces 9, each of which is pivotally connected to its respective leg 2 at a distance above the toggle connections and the upper ends of these braces hook into slots 10 in the yoke member 11. The legs 2 are pivoted at 12 to the yoke member 11 and the yoke 11 is in turn ivoted at 13 to the downwardly extending ends of a bracket 14.

The member 14 comprises a flat bar or strip which is bolted to the top 1 and has the ends bent at right angles and extending downwardly as shown in section in Fig. The yoke or hinged frame 11 is formed similarly to the member 14 except that the angularly bent ends overlap the downwardly ex tending ends of the bracket 14. The legs 2 are pivoted to the hinged yoke 11 at points inside of the downwardly extending ends of the bracket 14, as shown in Fig. 5. Thereby the legs 2 are substantially universally pivoted to the table top with a limited amount of opening movement and a limited spreading movement. The opening movement may be limited by the transverse portion of the yoke 11 contacting with the table top 1, as shown in Fig. 7; and the spreading movement is limited by the braces 9.

The rear legs 2 swing sidewise 0n the pivots 12, and may be folded against the top member 1 by rotating the yoke about the pivots 13. a The brace 4 is made of two parts hinged to break at 41. The lower end of brace 4 is hinged at 15 to the middle toggle link 6. and the upper end is pivotally connected at 17' to .the under side of the board.

The sloping'leg 8 is preferably made up or two bars 16. the lower ends of which are joined. and the upper ends of which are spread and pivoted at 18 to a bracket bolted to the table t p 1. The brace 19 is pivoted to the side bars 16 ot the leg 3 near the lower end thereof. The upper end of the brace 19 swings freely and is adapted to be seated in the bracket 5 for bracin the leg 3 in open vosition and supporting the front end of the top 1; The upper e ds of the bars 16 are out ofl at an angle as shown, so as to fit snugly against the board 1 when set up, thus contributin'g to the rigidity of the support.

A link 20 connects the two

braces

4 and 19 so that when one is moved the other willl follow. The link 20 is pivotally connected to the brace 19, and the member 4 in such location that the parts will lie properly against the under side of the top 1 when folded.

When the upper end of the locking brace 19 is released from its seat in the bracket 5 and crowded to the left, see Fig. 1, the rear brace 4 through the link 20 will be broken at the hinge or toggle joint 41. The lower end of the bent "brace4 will pull upward on the center link 6 and unlock the toggle and the buckling of the toggle will draw the legs 2 together as far as permitted by the play of the upper ends of the braces 9 in slots 10, and at the same time the legs 2 may be swung on pivots 13 until they lie against the top member 1 as in Fig. 4. v v

' When the rear legs are set up, as shown in Fig.3, their spread is limited by the braces 9.bef0re the toggle is fully extended. Ac-

' cordingly considerable force is required to locked position,

spring the legs and force the toggle all the way down. In this position the pivots 21 are below a straight line connecting the pivots22 and .the resilient inward pressure of the legs will hold the toggle stable in the Similarly the yoke 11 is pivoted at 13 in such manner that it bears against the bracket 14 and top member 1 and limits the rearward swinging of the legs 2 so that they spring appreciably when the toggle brace 4 is set up, thereby holding the joint in said brace locked and rigidly bracing the legs 2 with respect to the top member 1. v

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be. altered or omitted without departing from the spirit of this invention asdefined by thefollowing claims.

We claim:

1. In a folding table, a top member, a pair of legs hinged .to said top member, toggle linkage pivoted to said said legs for spreadingthe lower ends of the legs, and means spaced from said linkage for resist- 'ing said spreading and thereby springing the legs when the. linkage is extended to lock the toggle linkage. I

2. In a folding table, a top member, a

pair of legs hinged to said top member, toggle linkage pivoted to said legs for spreading the lower ends of the legs, and a toggled brace hinged at one end to the central portion of said linkage and. hinged at the other end to the top member and adapted to brace the legs when said brace is extended and to unlock the toggle linkage when the brace is collapsed,

.3.- In a folding table, a top member, a pair of legs hinged to said top member, toggle linkage pivoted to the legs for spreading the lower ends of the legs, means spaced from said linkage for resisting said spreading when the linkage is extended,

of said linkage and the top member and adapted to unlock the toggle linkage when the brace is collapsed.

4. In a folding table, a top member, a pair of legs hingedto said top member, toggle linkage pivoted to the legs for spreading the lower. ends of the legs, means spaced from said linkage for resisting said spreading when the linkage is extended, a collapsible brace for said legs, said braceextending betweenthe central portion of said linkage and the top member and adapted to unlock'the toggle linkage when the brace is collapsed, a third leg hinged to the table, a brace pivoted to the third leg and seating against the top member, and a rigid link between the two. braces and pivoted thereto.

5. In combination in a folding table, a top member, a pair of legs hinged to said top member, toggle linkage pivoted to the legs for spreading the lower ends of the legs, a toggled brace hinged at the lower end to said linkage and Jhinged at the upper end to the top member, a third leg hinged to the top member, a brace for the third leg extending between the same and said top member, and a connection between said braces.

6. In a folding table, a top member, a yoke pivoted to the top member for limited swinging, a pair of supporting legs pivoted in the yoke to swing transversely to the swing of the yoke, and a brace for each leg pivoted to the leg and engaging in a slot in the yoke to limit the outward pivotal movement of the leg.
