United States Patent 3,237,575 FOLDING LEG ASSEMBLY Charles 0. Larson, P.O. Box E, Sterling, Ill. Filed Mar. 1, 1965, Ser. No. 436,197 9 Claims. (Cl. 108-125) This invention relates to a folding leg assembly, and particularly to a folding leg assembly for supporting a table top or the like.

It is an important object of the present invention to provide an improved table leg assembly of the type having a brace connected between the leg and the underside of an associated table top, the improved leg of the present invention in the folded position fully enclosing and covering the brace and all of the parts connected with the brace to provide a neat and attractive arrangement of the parts in the folded position.

Another object of the present invention is to provide in a folding leg assembly of the type set forth an improved safety latch for locking the brace in the bracing position thereof.

In connection with the foregoing object, it is another object of the present invention to provide an improved structure releasably locking the safety latch in the latching position thereof with respect to the brace.

Still another object of the invention is to provide an improved safety latch in a folding leg assembly of the type set forth wherein the safety latch in cooperation with the brace provides an over-center toggle construction which serves to lock the leg in the folded position thereof.

A further object of the invention is to provide in a folding leg assembly of the type set forth an improved foot construction which fully closes the lower end of the leg and prevents marring of floors and the like that come in contact therewith, the foot construction also serving to assist in enclosing the brace and safety latch when the leg is in the folded position thereof.

A still further object of the invention is to provide an improved foot for a folding leg assembly of the type set forth wherein the foot is provided with an integral glide thereon.

Further features of the invention pertain to the particular arrangement of the parts of the folding leg assembly whereby the above-outlined and additional operating features thereof are attained.

The invention, both as to its organization and method of operation, together with further objects and advantages thereof, will best be understood by reference to the following specification taken in connection with the accompanying drawings, in which:

FIGURE 1 is a perspective view of the underside of a table having mounted thereon four of the folding leg assemblies made in accordance and embodying the principles of the present invention, three of the legs being shown in the extended operative position thereof and one of the legs being shown in the folded position thereof;

FIG. 6 is a view similar to FIG. 5 and showing the other side, of the folding leg assembly with the leg in the folded position thereof, additional portions of the leg 3,237,575 Patented Mar. 1, 1966 being broken away to illustrate the position of the brace and safety latch structure;

FIG. 7 is a view in horizontal section along the line 77 in FIG. 2; and

FIG. 8 is a side elevational view of the foot on the lower end of the leg of FIG. 2 as seen in the direction of the arrows along the line 88 thereof.

Referring to FIG. 1 of the drawings, there is illustrated a table 10, such as a card table, including a table top 11 on which are mounted four of the table leg assemblies 20 made in accordance and embodying the principles of the present invention, the leg assemblies being arranged so that each of the legs may be folded against the underside of the table top 11 along one of the edges thereof as illustrated by the table leg assembly 20 to the right in FIG. 1. The table top 11 as illustrated is generally square and includes a top surface 12, a peripheral surface or edge 13 and a bottom surface or underside 14.

Each of the folding leg assemblies 20 is identical in construction to the others, and accordingly, only one of the folding leg assemblies 20 will be described in detail in FIGS. 2 to 8, like reference numerals being utilized to identify like parts throughout the drawings. The folding leg assembly 20 includes a leg 21 which is generally U- shaped in cross section, as may be best seen from FIG. 7, and includes an elongated main wall 22 which extends the entire length thereof. Formed integral with the main wall 22 and extending substantially perpendicular thereto from the opposite edges thereof are two parallel, opposed and spaced-

apart side flanges

23 and 24 which cooperate with the main wall 22 to provide a hollow leg of essentially U-shaped cross section. The side flanges 23 and 24 extend the entire length of the leg 21, the upper outer corners of the

side flanges

23 and 24 being rounded as at 25 and 26 respectively to permit folding of the leg 21 as will be described more fully hereinafter, and the other end of the side flanges 23 terminating in lower

free edges

27 and 28, respectively.

The lower end of the leg 21 carries a foot 30 that comprises a plate 31 which is generally rectangular in shape and is formed integral with the main wall 22, the plate 31 being disposed substantially normal to the main wall 22 and extending therefrom in the same direction as the

side flanges

23 and 24, the plate 31 joining the main wall 22 at a juncture 32, the juncture 32 being cut out or necked as at 33 and 34 to facilitate the forming thereof. The plate 31 has formed integral with the outer end thereof an upturned front flange 35 which has the outer surface thereof aligned substantially in the same plane as the free edges of the

leg side flanges

23 and 24. The lateral edges 0 fthe plate 31 have thereon

integral side flanges

36 and 37 which extend substan tially normal thereto and upwardly toward the other end of the leg 21 on the outside of the adjacent

leg side flanges

23 and 24, respectively, whereby the plate 31 and the

side flanges

36 and 37 thereon cover and conceal the

lower edges

27 and 28 of the

leg side flanges

23 and 24, respectively (see FIG. 8 also).

Formed integral with the foot 30 is a guide 40 which is arranged substantially centrally of the plate 31 and extends downwardly therefrom terminating in a bearing surface 41 that is substantially fiat land is adapted to rest upon an underlying support surface such as a floor. Extending upwardly from the bearing surface 41 as illustrated in FIG. 2 is a generally conical wall 42 integral with the plate 31 and joining the bearing surface 41 at a gently rounded corner so that the glide 40 will not mar or scar an associated underlying floor.

The leg 21 is hingedly attached to the table top 11 by means of a pair of

leg brackets

51 and 52, the

leg brackets

51 and 52 including

mounting flanges

53 and 54, respectively, and support

flanges

55 and 56, respectively. The

mounting flanges

53 and 54 are fixedly secured to the underside 14 of the table top 11 as by a plurality of screws 57, the screws 57 passing through openings (not shown) in the

mounting flanges

53 and 54 and engaging the table top 11, three of the screws 57 having been illustrated as being utilized in mounting each of the

flanges

53 and 54. The

leg brackets

51 and 52 are mounted so that the inner surfaces of the

support flanges

55 and 56, which are disposed substantially perpendicular to the associated

mounting flanges

53 and 54, respectively, are spaced apart in a general parallel condition a distance such as to receive therebetween the upper end of the leg 21 as viewed in FIG. 2. A first rivet 53 passes through aligned openings (not shown) in the leg side flange 23 and the support flange 55, and a second rive-t 59 passes through aligned openings (not shown) in the leg side flange 24 and the support flange 56. In the construction, the upper end of the leg 21 including the upper edges of the main wall 22 and the

leg side flanges

23 and 24 are disposed immediately adjacent to the underside 14 of the table top 11 when the leg 21 is in the operative position, i.e., when the longitudinal axis of the leg 21 is substantially normal to the underside 14 of the table top 11. Because of the

rounded corners

25 and 26 on the

leg side flanges

23 and 24, respectively, the leg 21 can be pivoted in one direction, i.e., in the counterclockwise direction as viewed in FIG. 2, and only in that direction, from the operative position illustrated in FIG. 2 to a pivoted position illustrated in FIG. 5. In the pivoted position of the leg 21, the free edges of the

leg side flanges

23 and 24 are disposed against the underside 14 of the table top 11 throughout substantially the entire length thereof.

In order to maintain the leg 21 in the operative position thereof illustrated in FIGS. 2, 3 and 4, there has been provided a brace 60 which includes a pair of

arms

61 and 65. The arm 61 is provided with an offset 62 therein (see FIG. 3) and has one end pivotally connected to the leg 21 by means of a rivet 63, the rivet 63 passing through aligned openings (not shown) in the leg side flange 24 and the arm 61. The other end of the arm 61 and one end of the arm 65 are pivotally connected by a rivet 64 passing through aligned openings (not shown) therein, the adjacent end of the arm 65 extending downwardly beyond the rivet 64 as illustrated in FIG. 2 and carrying on the outermost portion thereof an abutment finger 67 that extends inwardly and over the other arm 61 and in contact therewith to pre vent further movement of the rivet 64 downwardly and to the right as illustrated in FIG. 2.

The other end of the brace arm 65 is pivotally connected to the underside 14 of the table top 11 by means of a brace bracket 70, the brace bracket 70 including a mounting flange 71 and a support flange 72, the mounting flange 71 and the support flange 72 being disposed substantially normal to each other. The mounting flange 71 is provided with a pair of openings (not shown) therethrough that received screws 57 that extend into the table top 11 to mount the brace bracket 70 on the underside 14 thereof. The adjacent end of the arm 65 has an off-set 66 therein and the outermost portion thereof is connected to the support flange 72 by means of a rivet 73, the rivet 73 passing through aligned openings (not shown) in the arm 65 and the support flange 72. As illustrated in FIGS. 2, 3 and 4, the abutment finger 67 on the arm 65 abutting the arm 61 prevents further movement of the rivet 64 downwardly and to the right, whereby the parts are illustrated in the bracing position thereof, the brace 60 in this position holding the leg 21 as illustrated in the operative position. When it is desired to pivot the leg 21 to the pivotal position thereof, it is necessary first to move the rivet 64 upwardly and to the left as illustrated in FIG. '2 so as to fold the

brace arms

61 and 65 with respect to each other.

In order to prevent inadvertent movement of the

brace arms

61 and 65 toward the folded position for the leg 21, a safety latch has been provided, the safety latch 80 at one end thereof being pivotally connected to the leg bracket 52 by means of the rivet 59. The other end of the safety latch 80 '(see FIG. 4) has a notch 82 therein, the material from the notch 82 being bent to form an integral abutment finger 81 (see FIGS. 2 and 3 also), the provision of the notch 82 in the safety latch 80 also forming a hook 83 on the outer end thereof. In the latching position of the safety latch 80, the lowermost edge thereof, as illustrated in FIGS. 2 to 4, bears against the upper edge of the brace abutment finger 67 and the notch 82 receives therein the peened over head 64a on the rivet 64 with the hook 83 releasably in engagement therewith. With the parts so arranged, it is not possible to move the rivet 64 upwardly and to the left as illustrated in FIG. 2, i.e., toward the leg folded position thereof, whereby the safety latch 80 serves firm-1y to hold the leg 21 and the associated parts in the operative position thereof. When it is desired to pivot the leg 21 to the pivoted position thereof, the safety latch 80 is releasably disengage-d from the head 64a on the rivet 64 by being slidably moved the-reover, whereby the safety latch 80 may 'be pivoted to the position illustrated by the dashed lines in FIG. 2. The rivet 64 can now be moved upwardly and to the left as seen in FIG. 2 to permit the leg 21 to be pivoted from the operative position illustrated in FIG. 2 to the folded position illustrated in FIG. 5.

As is best seen in FIG. 3 of the drawings all of the brace 60, the brace bracket 70 and the safety latch 80 are disposed between the lateral confines of the leg 21, and more specifically are disposed between the

leg side flanges

23 and 24, i.e., the lateral extent of the brace 60 and the brace bracket 70 and the safety latch 80 is less than the distance between the

leg flanges

23 and 24 and all of these parts are disposed therebetween. Furthermore, all of the brace 60, the brace bracket 70 and the safety latch 80 are disposed with respect to the leg assembly 20 in the direction of folding thereof so that when the leg 21 is moved to the folded position illustrated in FIG. 5, the brace 60, the brace bracket 70 and the safety latch 80 are all received within the leg 21. Furthermore, all of the parts including the brace 60, the brace bracket 70 and the safety latch 80 have a depth in the folded position thereof, i.e., extend downwardly from the underside 14 of the table top 11 as viewed in FIG. 2, a distance less than the distance from the edges of the

leg side flanges

23 and 24 to the inner surface of the main wall 22. As a result, the leg 21 can be folded flush against the underside 14 of the table top 11 as illustrated in FIGS. 5 and 6. It will be seen therefore that when the leg 21 is in the folded position thereof, the brace 60 and the brace bracket 70 and the safety latch 80 are all completely received within the leg 21 and are enclosed thereby so that the leg assembly 20 in the folded position has an unusually neat and attractive appearance and has no protruding parts that will catch on furniture on the clothing of a user, and has no sharp parts that will cut or mar surfaces against which the leg assembly 20 comes in contact.

Another important feature of the invention resides in the fact that the safety latch 80 in cooperation with the brace 60 not only serves to hold the leg 21 in the extended operative position illustrated in FIGS. 2-4 of the drawings, but these parts also serve releasably to lock the leg 21 in the folded position thereof, these parts cooperating to form an over-center toggle construction. Referring to FIG. 6 of the drawings, it will be seen that in the fully folded position of the safety latch 80, the hook 83 thereof contacts the underside 14 of the table top 11, whereby to space the lower edge of the abutment finger 81 a specific distance away from the underside 14. In the pivoting of the brace 60 toward the folded position of the parts, the brace arm 65, and specifically the upper edge thereof, contacts and abuts against the finger 81, whereby to stop further pivoting the brace arm 65 about the rivet 63 and thus to stop the center of the rivet 64 at a fixed point with respect to the underside 14 of the table top 11, that point being in a plane designated by the numeral 90 disposed substantially parallel to the underside 14. The center point of the rivet 64 reaches the plane 90 before the leg 21 is in the fully folded position thereof. The linkage, however, permits the leg 21 to continue being pivoted until it reaches the fully folded position at which time the center point of the rivet 63 is disposed in a plane diagrammatically illustrated as at 91, which plane 91 is fixed a second predetermined distance away from the underside 14, which second predetermined distance is less than the first predetermined distance; in other words, the center of the rivet 63 has moved past or over the center of the rivet 64, thus to give the usual over-center toggle action which serves releasably to hold the leg 21 in the folded position thereof.

Each of the leg assemblies 20 is preferably formed of metal, such as steel, aluminum, and the like,, and further are painted or otherwise treated for ornamentation purposes. The legs 21 may each be formed of a single piece of metal cut and shaped by folding and pressing as illustrated. The leg assemblies 20 can also be used to form with tops a wide variety of pieces of furniture other than the card table illustrated in the drawings, examples of other such pieces of furniture being banquet tables, serving tables, Work benches, banquet benches, coffee tables, and the like, and to this end the legs 21 may be formed with different lengths as required, such as 28 inches for higher tables and 16 inches for lower tables.

From the above it will be seen that there has been provided a folding leg assembly which fulfills all of the objects and advantages set forth above. More specifically, the improved folding leg assembly completely covers the brace and the brace bracket and the safety latch with the hollow U-shaped leg in the fully closed position thereof whereby to provide a particularly neat and attractive arrangement of the parts in the folded position, which arrangement also protects all objects with which the leg assembly may come into contact since there are no projections or sharp points or hooks thereon. There also has been provided an improved safety latch for locking the brace in the bracing position thereof, the safety latch including means releasably locking it in the latching position. The safety latch and the brace also cooperate to provide an over-center toggle construction which serves to lock the leg in the folded position thereof. There further has been provided an improved foot construction which fully closes the lower end of the leg so as to assist in enclosing the brace and safety latch of the legs in the folded position thereof. The foot further includes an integral glide which prevents marring of floors and the like that come in contact with the foot.
