8 Claims.

This invention relates to adjustable leg constructions for ironing boards, tables, benches or the like supports.

It is the primary object of the invention to have a three-legged adjustable height board that has the rear legs spread out when open, for sturdiness and well balanced support regardless of the open height and to have the legs fold to a relatively narrow width, so that they will fit within the width of the top when closedand will stand evenly regardless of any uneven surface, and wherein a compact package is had for storage and transportation.

It is another object of the present invention to provide an ironing board which can be adjusted to different heights so that the user of the ironing board may use the same while standing or may adjust it to a height such that it can be conveniently used while in a sitting position and wherein the adjustment may be effected by the simple operation of fitting a pin in any one of a series of holes on one of the legs to locate the vertical position of the slide on the leg.

It is another object of the present invention to provide a foldable leg construction for ironing boards, tables, benches and the like wherein one of the leg arrangements of crossed legs is formed in sections including an upper section pivoted to the other leg and independent lower leg sections adapted to be spread outwardly automatically as the legs are extended to their set-up or supporting position and to be automatically pulled inwardly as the legs are collapsed to the under face of the board and wherein the legs will be retained on the under face of the board by the passing over center of the pivotal connection between the one leg section and the other leg and wherein the legs will extend in opposite directions when collapsed upon the under side of the board and such that the adjustable legs will extend below one edge of the board to support the board free of the floor and wherein the other leg serves as the operating member to extend the legs and to collapse the same.

It is another object of the present invention to provide a foldable leg construction which may be formed of parts which may be either of metal, wood, plastic, or any other suitable material, with the several parts being of similar configuration and the construction operable in the same manner.

Other objects of the present invention are to provide an adjustable foldable leg construction for, ironing boards, tables, benches and the like which is simple. easy to operate, provide for a 2 sturdy and rigid support, inexpensive to manufacture, and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawings, in which Fig. l is a perspective view of an ironing board embodying the adjustable leg construction of the present invention.

Fig. 2 is a side elevational view of the leg construction extended to support the board at one elevation and illustrating in dotted lines the extent to which the board may be elevated to another elevation.

Fig. 3 is an elevational View. looking upon the le construction folded upon the under side of the table or ironing board and with thesame standing upon the ends of the leg sections.

Fig. 4 is a fragmentary elevational view of the legs with the leg sections of the one leg extended outwardly and illustrating with broken lines the manner in which the leg sections. are withdrawn as the legs are collapsed upon the under side of the board, the view being taken generallyon line 4-4 of Fig. 2 and looking in the direction of the arrows thereof.

Fig. 5 is a perspective view of one of the adjustable leg section supports.

Fig. 6 is a perspective view of the slide and retaining pins therefore.

Fig. 7 is asectional view taken board and on line l-l of Fig. 2.

Fig. 8 is a fragmentary perspective view of the one leg section and showing its slidable connection upon the bottom guide on the board.

Fig. 9 is a fragmentary sectional view similar to Fig. 8 showing a modified arrangement of a connection between the one section and the guide, the arrangement including a roller operable within the guide. Fig. 10 is a side elevational view ofthe board collapsed with the legs thrown slightly over a center point to fix them to the bottom face of the board.

Referring now to the figures, l5 represents an ironing board top to which leg construction indicated generally at 16 is connected to support the same. While there is being illustrated an iron-' ing board top, it will be apparent that such top could conform to that of a table, bench or other like article to which the leg construction of the present invention may be conveniently attached. The leg construction [6 comprises a long, single section leg I! and a multiple section leg l8 exthrough the tending transversely to the leg I! when the legs are extended and pivotally connected to the leg I! by a pivot pin l9, headed on both ends, and extending through angled channels 2| to which free leg sections 22 and 23 are respectively connected.

The angled channel members 2| are respectively connected to depending portions of a section 24 formed of side members and a transversely extending plate 25 bent at its ends and secured with the side members by rivets 2E. The

plate 25 has round side extensions 21 adapted to extend into guide brackets 28 fixed to the bottom of the board l5, Fig. 8. The section 24 can accordingly slide longitudinmly of the bottom of the board upon the guide brackets 28. The sections 22 and 23 can be adjusted outwardly as shown in Fig. 4 as the legs are extended fromv the board [5 to their supporting position and withdrawn inwardly to be aligned with the side members of the upper section 24 of the leg I8 as the legs are collapsed and broughtto the bottomof the board. These legs are pivotally connected to the angledchannel members 2i by pivot. pins 21 extending through holes 28 in the sidesof the channel.

Connectedto the sides of leg I l at points offset from the. pivotal connection of the leg I! with the leg I8, are respectively crossed links 3| and 32 connected respectively to. lower ' leg sections 22 and 23. As the legs" are extended'or collapsed, the leg sections 22" and 23 will be extended outwardly or withdrawn to broken line positions as shown in Fig. 4 and in alignment with the sides of section 24 of leg [8.

It willbe apparent that there has been provided a cross leg construction wherein one of the legs comprises as top section and laterally adjustable leg sections pivotally connected to the top sectionatapoint well below the bottom face of the board. The leg sections 22. and 23 are thus adjustable from a low point and independently of. an upper leg section, thereby leavingsthe upper leg. section 3 to slide along the bottom face. of the board in the parallel guide brackets 28-.

At a fixed point on the bottom face: of the board, long leg ll is pivotally connected to a bracket 34 fixed upon the bottom face of the board whereby the leg H is fixed against. longitudinal displacement and is limited to pivotal movement. The leg I! is formed of two members spaced throughout the upper extent of the leg but converging with one another at the lower extent of. the leg so as to accommodate a slide 36, Fig. 6, having side lug projections 31' to which tie rods 38 and 39 are respectively connected by a pin 4|. A chain 42 is. connected to the pin 4'! and has a cotter pin or bolt 43 connected to its. free end.

It will be apparent that the legs will be retained in their collapsed position against the bottom face of the top board independently of any fastening' device and by the movement of the pivotal connection between the legs to an overcenter position. It will be further apparent that the one leg is formed with adjustable sections which are pivotable from the lower end of an upper unitary section and at a point removed to a large distance from the bottom face of the. top board.

While various changes may be made in thedetail construction, it shall be understood that such changes shall. be within the spirit. and scope of the present invention as defined by the appended I claim:
