A Application filed August 16, 1926. Serial No. 129,450.

This invention relates .to improvements in ironing boards such as shown in our Patent No. 1,450,986 and has for its main objects to improve the stability of the. stand, increase the facility for folding and unfolding; to provide an improved folding stand which may be completely set up or folded by operating only one member; and to provide improved means for spreading and bracing the rear legs when the table is set up, and for drawing the rear legs together and folding the same against the table top in a more perfect manner when collapsing the. stand.

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

Figure 1 is a side view of the ironing board in the set-up or standing position.

Fig. 2 is a side elevation of the board when folded.

Fig. 3 is a rear elevation of Fig. 1.

Fig. 4 is a bottom plan view of Fig. 2.

Fig. 5 is a perspective view of the board when. partially unfolded.

Fig. 6 is taken substantially on the line 66 of Fig. 3.

Fig. 7 is a side elevation of .the board partly folded, in about the same condition as shown in Fig. 5.

Fig. 8 is a section on the line 8-8 of Fig. 4.

'Fig. 9 is taken on the line 9-9 of Fig. 1.

In this invention a toggle linkage connects the lower ends of the rear pair of legs, and a bar having a 180 degree hinged joint in the center portion is hinged to the under side of the table top and pivotally connected to the oint in the toggle linkage. lVhen the hinged bar is unfolded, it swings the rear legs to the standing position and bears against the toggle joint in the cross linkage to hold the legs rigid. The unfolding is facilitated and greater stability is secured by connecting the lower ends of the rear legs by braces directly connected to the bar at a point above the hinge in the bar. Thereby the table is firmly braced in the standing position, and, when the joint in the bar is broken upwardly, the connection serves to draw the rear legs together and swing them upwardly against the table top.

The central forwardly extending leg of the board is provided with a swinging brace, the upper end ofwhich bears against the top of the table to hold the central leg in the open position. Then a hinged link connects the swinging brace to the jointed bar, which holds the rear pair of legs, so that the two braces and the rear-and center legs move correspondingly to fold or unfold when the center leg brace is operated.

In the drawings, the top 1 is provided with a pair of legs 2 at the rear. end, a central forwardly extendingleg 3, abrace 4 for the rear legs, and a brace 5 for the central leg 3.

The rear legs 2 are hinged in a yoke 6 for a limited amount of spreading and the yoke (5 is pivotally connected to brackets or lugs 7 which are secured to the table top .1.

Thereby the legs 2 are hinged to fold into parallel relation against the under side of the top 1, andalso hinged for relative outward swinging or spreading when setup.

The central leg 3 is built up of two members which are pivoted to a bracket 8 which links 9, one of which, is pivotally connected to each of the legs, and the inner ends of the links 9 pivoted to angular brackets 10' which are rotatably secured on the sides of the lower end of the bar 4. The linkage just described is adapted to break or bend upwardly and is limited for swinging below the horizontal positionby means of the overhanging lugs 11 which are integral with the inner ends of the links 9 and positioned to bear against the upper surfaces of the angular members 10.

The bar 4 is collapsibly jointed nearer the lower end by means of a hinged strap 12 which is fastened to the under side of the bar 4. This joint also swings upwardly, but becomes rigid when the bar is extended because of the adjacent-ends of the two portions of the bar and the abutting relation at one side of the axis of the hinge. The upper end of the bar 4 is pivotally connected to the central portion of the under side of the table top 1. A pivotal connection comprising a rod 13 is provided between the upper portions of the members 4 and 5 so that the operation of the member 5 will cause corresponding movements for the member The unfolding movements are best illusloo end of the member has been forced slightly to the left from a position shown in Figure 1. The stiff connecting rod 13 pressed upwardly on the central portion of the bar 4 so that the joint 12 was bent upwardly. This caused the upper portion of the bar 4 to move to allow the upper end of the brace. 5 to swing, and also to relieve the pressure on the toggle joint between the links 9 so that the joints with the brackets 11 are bent upwardly.

In order to provide for better controlling the movement of the rear legs in folding,

and for stiffening the table'to prevent the table from moving back and forth when being used, rods 14 connecting the rear legs to the bar 4 above the joint 12 are provided. The rods are pivotally connected in the brackets 15, rotatably secured to either side of the bar 4, and also pivotally connected in brackets 16 secured to the inner surfaces of the legs 2.

When the'members are in extended position, the links 9 and the rods 14 are all under pressure against the resistance of the bar 4, which is then substantially rigid. This arrangement braces the legs 2 very firmly and resists longitudinal movement of the top. As soon as the joint 12 bends upwardly, the connection to the lowerlegs, comprising a lower end of the bar 4 and the links 9, becomes flexible so that the position of the legs 2 is controlled by the rods 14. As the upper portion of the bar 4 rotates clockwise, Fig. 1,

, the rods 14 are rotated substantially countergravity.

clockwise, to the position shown in Figure 4 where the movable members are all folded against the under surface of the table top. The rod connections also hold the lower end of the bar 4 centrally between the legs 2 and prevent one leg from swinging in farther than the other leg.

In unfolding the stand, the top of the table is grasped in one hand so that the" ends of the movable members drop down by brace 5 is grasped by the other hand and moved into position against the table top for bracing the central leg 3 in the set up position. The movement of the bar 5 through the connection 13 to the member 4 causes the Then" the swinging end of the operation of the .members relating to the ber 4 unfolds, as shown in Fig. 5, and when the member 5 is in opened position the member 4 isfully extended to spread the legs and bear outwardly on the joint between the cross links 9.

While but one specific embodiment of this invention has been herein shown and de scribed, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

We claim 1. In a folding stand, a top, a. pair of legs hinged to the top, a toggle linkage between the lower ends of the legs and pivotally connected thereto, a collapsible brace hinged to the topand operatively connected to said linkage, and a connection between said collapsible brace and each of said legs for stiffening the legs and for drawing the legs upwardly when the brace is collapsed and folded against the top.

2. In a folding stand, a top, a pair of legs hinged to the top, a toggle jointed connection between the lower ends of the legs, having a limited downward movement for spreading the legs, abrace hinged at one end to the top and pivotally connected at the lower end to the joint of said connection, said brace having a hinge joint breaking upwardly but locking when the brace is extended. and rods pivotally connected to the brace above the joint and to each of the-legs for holding the legs and said joint under tension when the legs are set up.

3. In a folding stand, atop, apair of legs hinged to the top and movably intercom rear legs 2. The lower portionof the memnected at the lower ends, a centrally hinged ends of said legs, and a rod pivotally connected to each leg and to the upper portion of the bar, for drawing the legs upwardly when the bar is folded against the top.

Signed at Portland this 3rd day of August, 1926.
