reference is first made to fig1 illustrating a collapsible table in accordance with the present invention generally designated 10 comprising two pivotable table top half sections 14 and 16 hingedly connected to one another and foldable about a pivot axle 18 ( see in fig3 a and 4a ), extending transversally at a center line 20 of the table 10 . in the open position of fig1 the half sections 14 , 16 are coplanar . the table 10 is supported by six legs arranged in pairs and designated 22 a and 22 b ; 24 a and 24 b ; 26 a and 26 b and will be discussed in more detail hereinafter . the table 10 is foldable / collapsible between an open position as illustrated in fig1 where the table top is supported by the legs , and a closed / folded / collapsed position as illustrated in fig2 . also seen in fig2 is a latch 30 to retain the half sections 14 and 16 in the closed , overlapping position . in fig3 a the table 10 is illustrated from its bottom side and as can be seen at each of the half sections 14 and 16 , in the present case made of plastic material , is formed with a peripheral skirt portion 34 , increasing the rigidity and load bearing ability of the table 10 , and further , providing space for accommodating the legs and the support members , in the closed position , as will become apparent hereinafter . it is further noticed in fig3 a that the ends of legs 22 a and b and 26 a and b are attached to a transversed support member 40 pivotably articulated to an under surface 42 of the half sections 14 and 16 by means of hinge portions 44 . the arrangement is such that the under surface 42 of the half sections 14 and 16 comprises several hinge segments 50 ( see fig3 b ) integrally formed therewith and adapted for snap - type engagement with a receptacle hinge cavity 54 integrally formed with the transverse support member 40 . the hinge segments 50 are sized and shaped such that the transverse support members 40 are snappingly displaceable in a toggle type manner between an erect position ( fig3 a and 3b ) and a collapsed position ( fig4 d ) and further such that in the erect position a surface 58 of the support member 40 flushingly bears against a corresponding surface 60 at the under surface 42 . further noticed in fig3 a there are provided four longitudinal support members 64 , each extending along a corresponding edge of the respective half section . the longitudinal support members 64 are pivotably articulated to the under surfaces 42 of the half sections 14 and 16 , in the same manner as disclosed hereinabove in connection with the transverse support members 40 , with particular reference to fig3 b . a central support member 68 is mounted on the common pivot axle 18 pivotably attaching the half sections 14 and 16 whereby at the open position of the table 10 , when the two half sections are coplanar , the central support member bears against corresponding portions at the undersurface 42 of the half sections , to thereby provide increased load bearing and stability of the table . legs 24 a and 24 b extend from the central support member 68 . in accordance with other particular embodiments ( not illustrated ) the central support member 68 may be omitted entirely or may be designed to have one central leg or no legs at all . as can best be seen in fig3 a , at the open position of the table 10 , all of the support members 40 and 64 stand erect and perpendicular to the undersurface 42 ; the transverse support members 40 and the central support member 68 extend parallel to the pivot axle 18 ; and the longitudinal support members 64 extend at right angles thereto . in this position when all of the support members 40 and 64 are erect , a closed box - like support structure is formed by them and each support member engages at its respective ends corresponding ends of a mating support member by means of a snap - type engagement as will be described in more detail with reference to fig3 c and 4b . the construction of the box / frame like structure gives rise to a table of improved rigidity and load bearing ability in both the longitudinal and transverse directions . the support members 40 and 64 are retained in their erect position , in accordance with an embodiment of the present invention , both by the toggle - type hinge arrangement of the support members to the under surface 42 of the half sections 14 and 16 and by the snap - type engagement between adjoining ends of respective support members . an example of such an engagement arrangement is seen in fig4 b , which is an enlargement of the portion marked iv in fig4 a , where the longitudinal support member 64 comprises four lateral projections 70 a , 70 b , 70 c and 70 d designed for snap - engagement within corresponding receptacles designated 72 a , 72 b , 72 c and 72 d , respectively , formed at a leg support portion 76 receiving leg 26 b of the transverse support member 40 . thus , displacement of a longitudinal support member from its erect position to its collapsed position requires some force thereby to prevent unintentional displacement thereof . fig3 c is an enlargement of the portion marked iii in fig3 a whereby an end portion of the lateral support member 64 is formed with three projections 82 a , 82 b and 82 c designed for snap - engagement within corresponding receptacles ( not seen in this position ) formed in leg receptacle 86 supporting leg 24 b of the central support member 68 . this arrangement also requires application of some reasonable force to thereby prevent unintentional collapsing of the longitudinal support members 64 . with further reference made to fig4 a to 4e , it will now be explained how the table 10 is collapsed / folded from its open position as illustrated in fig1 and 3a to its closed / folded position as in fig2 . at a first step ( fig4 a ) the four longitudinal support members 64 are collapsed by pivotally displacing them inwardly in the direction of arrow 90 . fig4 c illustrates the table 10 after the four longitudinal support members 64 have been collapsed and lie flush against the under surface 42 of the half sections 14 and 16 ( fig4 c ). only at this point , after the longitudinal support members 64 of each half section 14 and 16 have been collapsed , the transverse support members 40 may be collapsed by turning them inward as indicated by arrows 94 in fig4 c such that the transverse support members 40 lie over the already folded longitudinal support members 64 . it is noticed that in the position shown in fig4 d the collapsed transverse support members 40 and their respective legs 22 a , 22 b and 26 a , 26 b do not occupy the entire space formed by the peripheral skirt 34 , thereby allowing sufficient space to accommodate the central support member 68 and the central legs 24 a and 24 b . at a final step the half sections 14 and 16 are pivotally displaced towards one another ( arrow 98 in fig4 e ) until obtaining the fully closed position as in fig2 . retaining the table 10 in its closed position , may be obtained by closing latch 30 ( fig2 ) or by snap type arrangement as illustrated for example in fig4 e wherein the skirt portion 34 of the half section 14 comprises two projections 102 fitted for snap engagement within corresponding two receptacles 104 fitted on the skirt 34 of half section 16 . finally , carrying the table 10 from one place to another may be facilitated by a handle 110 formed at half sections 14 by means of a depression at the skirt portion 34 enabling one to insert his hand between the half section when the table is in its closed position . in accordance with a variation thereof , such a depression may be formed also at the half section 16 and optionally also at the opposed sides thereof . as an alternative , there may be provided a handle 114 ( fig4 e ) displaceable between an extracted position as shown , and a retracted position ( not shown ) merely by folding or sliding it about a suitable hinge or rack . while there has been shown an embodiment with several modifications of the invention , it will be appreciated by a person of the art that many changes may be made therein without departing from the spirit and the scope of the invention , mutatis mutandis .
a collapsible table includes a table top formed of a pair of pivotable table top half - sections hinged to one another at their adjacent edges along a center - line of the table and displaceable between an open position where the half - sections are coplanar , and a folded position where the half - sections overlap one another . each half - section has at an undersurface thereof a transverse support member pivotally articulated thereto with a leg associated with each lateral edge of the transverse support member , and a pair of longitudinal support members pivotally articulated to the undersurface . the support members are displaceable between erect and collapsed positions whereby the transverse support member is prohibited from collapsing as long as at least one of the longitudinal support members is erect .
