referring now to the drawings , and more particularly , to fig1 and 2 , one embodiment of a collapsable table 10 , made according to the present invention is disclosed . table 10 includes a table top 20 , a pair of interlocking legs 30 and 40 , and a leg receiving block 50 , see fig2 . table top 20 includes substantially planar top surface 22 and bottom surface 24 . in the preferred embodiment , table top 20 includes a downwardly depending flange 21 about the perimeter of the table top . the depth of the flange below the undersurface of the table top is preferably equal to the combined thicknesses of the essentially flat legs 30 and 40 for storing purposes , as will hereinafter be explained . the table may be made of any of the common materials such as wood , plastics , or metals . it is also contemplated that the top surface 22 of table top 20 may be venerred , as in standard table tops . referring now to fig2 , and 4 , the leg receiving block of one preferred embodiment of the present invention may be seen to advantage . leg receiving block 50 may be round in configuration , in which case the diameter of block 50 must be slightly smaller than the central openings 31 and 41 of legs 30 and 40 , respectively , as shown in fig1 . it is an essential element of the present invention that the receiving block 50 be of lesser width than the openings in the legs for proper storage of the legs on the undersurface of the table top . block 50 includes two notches 51 which extend the complete diameter of the block and intersect one another at substantially right angles . depth of the notches should be sufficient to prevent any rotation or lateral movement of the legs in respect to the block . block 50 may be mounted to the undersurface 24 of table top 20 in the center of the undersurface by means of glue , screws , or other conventional fastening means . leg receiving block 50 may be made of any suitable material . as may be seen in fig1 and 3 legs 30 and 40 of collapsable table 10 are essentially plate like , having vertical coplanar opposing surfaces . each of the legs 30 and 40 , contain at their uppermost edge a pair of horizontally extending , rectilinear , table top contacting surfaces separated by a recede portion 32 and 42 , respectively . the recede portions are flat and extend horizontally parallel with the table top contacting surfaces . leg 30 includes a pair of oppositely disposed grooves 33 extending vertically from the center of recede portion 32 to an opening 31 located in the center of the leg . leg 30 also contains a vertical slit 35 , in alignment with grooves 33 , extending from opening 31 to a second recede portion 34 which defines two floor contacting shoes 36 and 37 . leg 40 has the same general configuration and the same dimensions as leg 30 . leg 40 includes a vertical slit 45 extending from first recede portion 42 to a centrally located opening 41 , and a pair of oppositely disposed grooves 43 extending from opening 41 to a second recede portion 44 which defines a pair of floor contacting shoes 46 and 47 . in assembling collapsable table 10 , leg 30 is lowered onto leg 40 so that the edges of the leg which define slit 35 interlockingly engage the grooves 43 of leg 40 . in the process , the edges of leg 40 defining slit 45 interlockingly engage grooves 33 of leg 30 . it will therefore be seen that legs 30 and 40 are locked together at right angles one to the other in an immovable relationship . table top 20 is then lowered onto the uppermost surfaces of legs 30 and 40 so that the horizontally extending , rectilinear , top surfaces of recede portion 32 and 42 mate with and interlockingly engage notches 51 of leg receiving block 50 . the rectilinear top edges of the legs protruding above the recede portions concurrently make flush contact with bottom surface 24 of table top 20 . the process is simply reversed for dismanteling . for storage , or for carrying , legs 30 and 40 are placed flat against one another with the planar side surfaces of the legs laying flush against one another and against the bottom surface 24 of table top 20 as may be seen to advantage in fig4 . the centrally located circular openings 31 and 41 of legs 30 and 40 respectively , encase leg receiving block 51 in a snug relationship . the uppermost surface of the outermost leg is flush with the top surface of leg receiving block 51 and depending flange 21 of table top 20 while in this stored position . referring now to fig5 and 6 , a second preferred embodiment of the present invention may be seen . the second embodiment differs from the above described embodiment primarily in the square shapes of top and legs and in the configuration of leg receiving block 50 &# 39 ; and central openings 31 &# 39 ; and 41 &# 39 ; of legs 30 &# 39 ; and 40 &# 39 ;, respectively . in the second embodiment the central leg openings and the leg receiving block are both square , the openings being slightly larger than the block for convenient storage as previously mentioned . the square configuration of the block and openings , while lacking the advantage found in the circular block and openings as previously described of storage of the legs at any angle relative to the block , does have the particular advantage of holding the legs in a secure and non rotatable position relative to the block and to the undersurface of the table top . in either embodiment , the table may include a first locking means , locking flanges 70 located on the bottom surface of receiving blocks 50 or 50 &# 39 ; as may be seen in fig4 and 6 . flanges 70 are horizontally rotatable about pins 71 , and in operation are rotated so that the undersurface of the flange comes in contact with the uppersurface of the side of a leg to hold the legs flush against the undersurface of the table top for storage and for carrying . the table may also contain a second locking means to lock the legs to the undersurface of the table top and leg receiving block to maintain the table in an assembled position . for this purpose , a flange 80 is mounted on the bottom surface of the receiving block adjacent the intersecting notches 51 as may be seen in fig2 and 6 . flange 80 is rotated to engage flange receiving slots 84 which are located adjacent to and parallel with the top surface of the first recede portion of the legs and transverse to the vertical grooves and slits of the legs as may best be seen in fig1 and 5 . having thus described in detail a preferred selection of embodiments of the present invention , it is to be appreciated and will be apparent to those skilled in the art that many physical changes could be made in the apparatus without altering the inventive concepts and principles embodied therein . the present embodiments are therefore to be considered in all respects as illustrative and not restrictive , the scope of the invention being indicated by the appended claims rather than by the foregoing description , and all changes which come within the meaning and range of equivalency of the claims are therefore to be embraced therein .
a collapsable portable table including a table top and a pair of interlocking legs . the table top , on its undersurface , contains a leg receiving block which interlockingly engages the legs . the legs each have an opening substantially in the center thereof which encase the receiving block when the legs are stored flush against the undersurface of the table top for carrying or for storage . locking means are also provided for retaining the legs either in the standing or in the collapsed position .
