- the leg assemblies 23 and 24 are pivotally connected to the members 21 and 22 adjacent the ends of the table for swinging movements between extended positions, shown in FIG. 1, where the leg assemblies extend substantially perpendicular to the table top 20 in order to support the table top 20 on a floor 26, and retracted positions shown in FIG. 2 where the leg assemblies 23 and 24 are folded against the underside of the table top 20 for storage of the table.
- the table top 20 may have any configuration, in the present instance it is generally rectangular and has rounded corners, as shown in FIG. 2
- the table top 20 may be made of any material but preferably includes a relatively thick stiff particle board 27 (FIG. 6), a formica top sheet 28 and a plastic backing sheet 29, the sheets 28 and 29 being secured to the board 27 as by gluing.
- the top 20 preferably further includes a resilient cushion 31 (see FIG. 6) at its edges, such as a vinyl bullnose.
- the cushion 31 may be secured to the particle board 27 as by forming a groove 32 in the edge of the board 27 entirely around the periphery thereof, and inserting a tongue 33 formed on the inner side of the cushion 31, into the groove 32.
- The-tongue 33 is secured in the groove 32 as by a plurality of nails 34 which are driven through the backing sheet 29, into the board 27 from the underside thereof, and through the tongue 33.
- the two support members 21 and 22 respectively include at least portions which extend parallel to each other and adjacent the longitudinally extending edges of the table top 20.
- each of the support members is U-shaped, the member 21 including a central portion 41 and two arms 41a and 41b and the member 22 including a central portion 42 and two arms 42a and 42b.
- the central portions 41 and 42 comprise the previously mentioned parallel portions of the two members 21 and 22.
- Each of the support members 21 and 22 is, in the present instance, channel shaped in cross section and includes two flanges 46 and 47 and a web 48, the flange 47 being wider than the flange 46 and the flange 47 being positioned against the backing sheet 29 at the underside of the table top 20.
- the arms 41a and 41b are respectively secured to the arms 42a and 42b by splice plates 43 and 44.
- the splice plates 43 and 44 are also preferably channel-shaped in cross section with the widths of the flanges of each splice plate being slightly less than the width of the flange 46 as shown in (FIG. 6) and the width of the web of each splice plate being slightly less than the web 48 of each support member 21 and 22.
- the splice plates 43 and 44 are nested within the members 21 and 22 with a relatively snug fit, as shown in FIGS. 4 and 6.
- the splice plates 43 and 44 rigidly secure the two members 21 and 22. together.
- the ends of the arms 41a and 41b of the member 21 and the ends of the arms 42a and 42b of the member 22 are moved into end-to-end abutting relation as shown in FIG. 2, and the splice plates 44 and 43 are nested within the members 21 land 22 at locations where they overlap the adjoining ends of the arms of the members 21 and 22, and then the splice plates 43 and 44 are secured to the members 21 and 22 as by rivets 49 (FIGS. 3, 4 and 6).
- the rivets 49 rigidly secure the members 21 and 22 together and the snug fit nesting relation between the splice plates and the members tends to prevent play or looseness at the connections between the two mem bers 21 land 22.
- the two members 21 and 22 are also secured to the top 20 as by screws 51 (FIGS. 2, 4 and 6) which are positioned in holes formed in the arm 47 of each of the two members 21 and 22 and are screwed into the table top 20 from the underside thereof. As shown in FIGS. 2 and 6, the members 21 and 22 are positioned against the backing sheet 29 on the underside of the top 20 and adjacent the edges thereof. As previously stated, the corners of the top 20 are preferably rounded, and the corners of the members 21 and 22 are preferably similarly rounded and follow the configuration of the table top 20.
- Each of the two leg assemblies 23 and 24 comprises a pair of leg members 56 and 57 (FIGS. 1 and 2) and a cross brace 58, the members 56 to 58 of each of the leg assemblies preferably being made of tubular metal.
- each of the legs 56 and 57 has fastened thereto suitable glides or leg cups 59, and at their upper ends the legs 56 and 57 of each leg assembly are rigidly secured as by welding to the associated cross brace 58.
- the legs 56 and 57 of each leg assembly are secured to the associated cross brace 58 such that, when the legs are extended, they angle downwardly and toward the adjacent longitudinally extending side of the tabl in order to increase the stability of the table.
- the center portions of the two U- shaped members 21 and 22 which are adjacent the longitudinally extending edges of the table top 20, are spaced apart and are generally parallel with each other, and when the center portions 41 and 42 are in this position the leg assemblies 23 and 24 are pivotally secured to the remainder of the table.
- the ends of the cross bar 58 of each leg assembly are pivotally connected to the foregoing center portions of the members 21 and 22 merely by being seated over circular bushings 61 (FIGS. 7 and which are secured to the webs 48 of the members 21 and 22.
- Each of the bushings 61 is secured to the associated member as by a rivet 62 which is positioned in a hole formed in the web 48 and in a hole 63 formed in the bushing 61, the ends of the rivet 62 when flattened holding the bushing 61 assembled with the member.
- a washer 64 may also be provided between each bushing 61 and the inner end of the associated rivet 62.
- the outer diameter of each bushing 61 is slightly less than the internal diameter of the cross braces 58, so that the bushing 61 may be inserted into the ends of the cross braces 58.
- each bushing telescopes into a cross brace and thus these two parts include engaging surfaces which are held in engagement by the means for securing the two members together.
- the table preferably further includes a center support 71 (FIGS. 2, 7 and 8) which extends longitudinally of the table between the cross braces 58 of the leg assemblies, at
- the center support 71 is generally Z-shaped in cross section and includes a relatively wide flange 72, a relatively narrow flange 73, and a web 74.
- the wider flange 72 is positioned flat against the underside of the table top 20, and the length of the web 74 is slightly greater than the outer diameter of the cross braces 58 of the leg assemblies.
- the center support 71 is supported by the two cross braces 58 of the two leg assemblies 23 and 24 and is secured to the cross braces 58 by a pair of plates 76 (FIGS. 2, 7 and 8). As shown in FIG. 8, adjacent each end of the center support 71 is formed a notch 77 having a width substantially equal to the outer diameter of the cross brace 58, the cut-out extending entirely through the flange 73 and substantially entirely through the web '74 of the center support 71, thereby leaving only the wider flange 72 at each notch '77.
- the flange 72 of the center support 71 is positioned over the upper sides of the cross braces 58, with the notches 77 receiving the cross braces 58, and the plates 76 are positioned across the undersides of the cross braces 58 and are secured to the web 74 of the center support 71 as by rivets 78. As shown in FIG. 7, the plates 7 6 are positioned flat against the same side of the web 74, from which the narrower flange 73 extends.
- the plates 76 also have arcuate notches 79 formed therein, which conform to the configuration of the cross braces 58, so that the plates 76 fit against the undersides of the cross braces 58 and hold them assembled with the cross braces 58.
- the center support 71 may also be secured to the underside of the table top 20 as by a plurality of screws 81 (FIGS. 2, 7, 8 and 9) which are positioned in holes formed in the wider flange 72 of the center support 71 and are threaded in the table top 20 from the underside thereof fl hus, the center support 71 serves to render the table rigid by being secured to the leg assemblies 23 and 24 and to the table top 20 and it supports the center area of the table top.
- each leg brace 88 and 89 preferably comprises a rod like member which is flattened at both ends 91, the flattened ends 91 being bent to extend at angles relative to the remainder of the leg braces so as to form an elongated S shape, as shown in FIG. 7.
- the outer end of each leg brace 88 and 82 is pivotally connected to the adjacent leg by an elongated rivet 92 (FIGS.
- leg braces 88 and 89 of each pair are connected to each other and are slidably connected to the center support 71.
- the web 74 of the center support 71 has a longitudinally elongated slot 96 (FIG.
- each pair of the leg braces 88 and 89 is slidablyconnected to the center support 71 by a rivet 97 which extends through holes formed in the inner ends of the cross braces 88 and 89 and through the adjacent slot 96.
- the connection between each pair of the leg braces 88 and 89 and the center support 71 also includes a tubular bushing 98 which is positioned around the rivet 97 and between the adjacent ends of the leg braces 88 and 89. At a point midway between the ends of the bushing 98, an annular groove 99 is formed in the outer periphery of the bushing 98.
- each slot 96 formed in the center support 71 is slightly greater than the diameter of the bushing 98 at the groove 99 but less than the diameter of the bushing on each side of the groove 99, so that the grooved portion of each bushing 98 may be received within the slot 96 of the center support 71 and slid along the length of the slot 98 without substantial lateral movernent of the bushing 98 and the inner ends of the leg braces 88 and 89.
- the end of each slot 96 which is adjacent the center of the table, is enlarged as at 101 (FIG. 8) sufliciently to permit end portions of the bushings to be inserted into the slots 96.
- the bushing 98 is positioned in the enlargement 101 of the slot 96 and the groove 99 of the bushing 98 is slid into the main portion of the slot 96.
- the rivet 91 is then inserted through the holes in the leg braces 88 and 89 and through the bushing 98, and then peened to secure the parts together.
- the leg braces 88 and 89 serve to steady the legs 56 and 57 when the leg assemblies are in their extended positions.
- the bushings 98 slide in the slots 96 longitudinally of the table toward each other, and as the leg assemblies are moved to their extended positions, the bushings 98 move toward the ends of the table.
- the length of the slots 96 is such that the bushings 98 are adjacent but do not reach the enlarged portions 101 of the slots 96, as shown in full lines in FIG. 8, when the leg assemblies are retracted.
- the bushings 98 are at the opposite ends of the slots 96 and the legs 56 and 57 of each leg assembly 23 and 24 angle downwardly and toward the adjacent end of the table in order to improve the stability of the table.
- the latch mechanisms 86 and 87 are designed to hold the bushings 98 at the longitudinally outer ends of the slots 96 in order to lock the leg assemblies in their extended positions.
- adjacent the longitudinally outer end 102 of each slot 96 is formed with an offset or hook-shaped portion 102a which curves downwardly from the table top 20 and then toward the center of the table.
- the bushing 98 slides to the end 102 of the slot 96.
- the swinging force on the leg assembly is then released and the braces 88 and 89 are pressed downwardly, causing the bushing 98 to slide into the offset portion 102a of the slot 96.
- each latch mechanism 86 and 87 includes a manually shiftable sliding latch 103 (FIGS. 7 and 8) which is slidably connected to the web 74 of the center support 71 adjacent the oflset portion 102a of the slot 96, the latch being slidable longitudinally of the table between an unlocked position shown in full lines in FIGS. 7 and 8 and a locked position shown in dashed lines in FIGS. 7 and 8.
- Each latch 103 includes a longitudinally extending plate portion 104 and a laterally extending handle portion 105. The plate portion 104 of each latch 103 is positioned flat against the web 74 of the center support 71, and includes a slanted edge 107 on the longitudinally inner end at the lower side thereof.
- Each latch member 103 is slidably connected to the center support 71 by a shouldered rivet 111 which extends through a hole formed in the latch 103 and through a hole 112 formed in the web 74 of the center support 71 (FIG. 8). While either the hole in the latch or the hole 112 in the web 74 may be enlongated to permit movement of the latch 103, in the present instance the hole 112 is elongated to form a slot. The width of the slot 112 is greater than the size of the hole formed in the latch 103, and the larger diameter portion of the rivet 111 is located within the slot 112 whereas the smaller diameter portion of the rivet is located within the opening in latch 103.
- the edge of the plate portion 104 which is adjacent the table top fits closely against the flange 72 of the center support 71, and the latch 103 is thus prevented from turning about the axis of the rivet 111.
- the rivet 111 slides from one end of the slot 112 to the other end as the latch 103 is moved between the locked and unlocked positions.
- edge 107 makes a relatively small angle relative to the direction of movement of the latch 103, and consequently a force on a leg assembly tending to pull the bushing 98 out of the offset portion 102a of the slot 96 could not easily force the latch 103 longitudinally toward the adjacent end of the table to the unlocked position.
- the table may be easily manufactured and quickly assembled by securing together the parts of the two leg assemblies 23 and 24, fastening the latches 86 and 87 to the center support 71, and securing the bushings 61 to the two members 21 and 22.
- the top 20 is placed on the floor with the bottom side thereof facing upwardly, the center support 71 is positioned on the table top, the cross braces 58 of the two leg assemblies 23 and 24 are positioned in the notches 77 formed in the center support 71, the plates 76 are secured to the support 71 over the cross braces 58, and the leg braces are connected to the support 71.
- the two U-shaped members 21 and 22 of the support channel 22 are then brought together and the bushings 61 are inserted into the ends of the cross braces 58, and the splice plates 43 and 44 are rigidly secured tothe arms of the members 21 and 22.
- the two members 21 and 22 are held in rigid assembled relation with each other and with the leg assemblies 23 and 24 by the splice plates, the connection between the leg assemblies and the members 21 and 22 of course being sufficiently loose to permit pivotal movement of the leg assemblies.
- the members 21 and 22 and the center support 71 are secured to the table top 20 as by screws.
- leg assemblies 23 and 24 are always connected to the members 21 and 22 by bringing the two members 21 and 22 together and securing them by the splice plates.
- FIGS. 11 to 15 illustrate a generally similar but alternate form of the table.
- the table illustrated in these figures comprises a rectangular top 120, a pair of identical U-shaped elongated support members 122 and 123, two splice plates 124 and 125, two leg assemblies 127 and 128, a center support 129, two latch mechanisms 131 for releasably holding the leg assemblies 127 and 128 in extended positions, and bushings 142.

- the offset flange of the support member 163 forms a recess 167 and the portion of the table top between the underside thereof and the groove 162 forms a tongue 168 which is snugly received within the recess 167.
- the tongue 168 is preferably shorter than the remainder of the top by an amount substantially equal to the thickness of the material from which the support member 163 is formed, so that the laterally outer surface of the support channel 163 is substantially flush with the laterally outer surface of the table top 161 above the support member 163.
- the construction shown in FIG. 18 includes a relatively thin table top 171 having a rabbet 172 formed in the lower outside corner thereof, to form a tongue 173 which extends into a recess 174 formed in a support member 176. While the tongue 173 is preferably received within the recess 174 in a snug fit relation, to further rigidify the table and prevent the channel 176 from pulling away from the table top 171, a series of nails 177 are driven through the support member 176 and into the tongue 173 from the underside thereof.
- One means for driving the nails 177 into the member 176 and the table top 171, comprises a base or support 178 which is positioned against the support member 176 and the table top at the upper outside corners thereof and a hammer 179 for driving the nails 177.

- the table top 191 and the member 192 shown in FIG. 20 are similar to the top 181 and member 182 shown in FIG. 19 and to the table top 171 and member 176 shown in FIG. 18.
- a lancing tool 193 is provided to lance the member at spaced locations as at 194, the lances 194 extending into the underside of the table top 191 adjacent the outer periphery thereof.
- a base or support 196 is preferably provided opposite the lancing tool 193 to support the member 192 and the table top 191 during the lancing operation.
- the lancing tool 193 has a relatively sharp knife edge 195 which forms a lance 194 when the tool 193 is forced against the member 192 and the table top 191.
- Sti l other means, not shown, for securing the support member to the underside of the table top may be utilized, including a rolling or crimping tool which rolls along the support member and deforms a portion of the support member into the table top.
- the support member may also be secured to the table top by gluing, if desired.
- a table somewhat similar to that shown in FIG. 16 could be provided wherein the flange 154 is positioned in a groove substantially midway between the upper and lower edges of the table top.
