Referring to the drawings more specifically A indicates generally the intermediate portion of the table top and BB designates slidable end extensions carried on the intermediate portion A. The table top A and the extensions B-B each embody rectangular panels 15 and 16 respectively which panels are of corresponding width and are disposed in longitudinal alignment with the inner end portions of the panels 16-16 superimposed on the end portions of the panel 15 in superficial sliding contact therewith, as will presently be described, so that the end panels 16-16 may be shifted lengthwise relative to the intermediate panel 15 to from its contracted position as shown in Fig. 1 to an extended position as indicated in dotted lines in Fig. l and as shown in full lines in Fig. 3.

Hingedly mounted on one margin of the panel 15 is a rectangular leaf 17 corresponding in length to the panel 15 and positioned in transverse alignment with the latter and hingedly mounted on the corresponding margin of the panel 16 of each of the extensions B-B is a rectangular extension leaf 18 corresponding in length to the panel 16 and disposed in transverse alignment therewith. The leaf 18 corresponds in width to the leaf 17 and is disposed in longitudinal alignment with the latter with its inner end portion overlying and slidably contacting the adjacent end portion of the leaf 17.

The leaves 17-18 are adapted to be disposed in horizontal alignment with the table top 15 and extensions 16-16, or to be folded to overlie the panels 15 and 16-16, or disposed in various outwardly extending angles or inclinations relative thereto.

Thev several panels 15-16 and leaves 17-18 are formed of stiff, thin sheet material having smooth flat surfaces on the opposite sides thereof.

Fixedly mounted on the underside of the panel 15 is a pair of parallel guide rails 19-19 which rails extend adjacent the longitudinal margins of the panel 15 and project a short distance from the opposite ends thereof. The rails 19-19 are formed on the inner faces thereof with longitudinal tongues 20-20 which extend throughout the lengths of the rails 19-19.- Mounted on the leaf 17 adjacent its inner margin is a guide rail 21 which parallels the rail 19 and like the latter projects at its ends from the opposite ends of the leaf 17. The rail 21 is formed with a tongue 22 extending throughout the length thereof on its inner side. The outer margin of the leaf 17 is fitted with a rail 23 formed with a longitudinally extending open ended channel 24 one wall of which abuts against the upper side of the leaf 17 and the other wall of which is spaced from the under face of the leaf 17 to provide the rail 23 with a slide-way on its inner side adjacent the inner face of the leaf 17. The panel 15 and leaf 17 are united intermediate their ends by a hinge 25 as shown in Fig. 12.

As particularly shown in Fig. 13 the panel 16 of each of the end extensions B has aflixed thereon a pair of parallel rails 26-26 formed on their outer faces with longitudinally extending channels 27-27 which slidably receive the tongues 20-20 on the rails 19-19. The inner end portions of the rails 26-26 are spaced from the panel 16 to provide a slot 28 for the reception of the outer end of the panel 15 and to afford a sliding connection between the panels 15 and 16. In order to stabilize and maintain the free ends of the rails 26-26 in proper spaced relation the end portions thereof are con-- nected by a tie bar 29.

The leaf 18 is fitted with a rail 30 extending along the length thereof adjacent its inner margin which rail is provided with a channel 31 slidably engaged by the tongue 22 on the rail 21. The rail 30 like the rails 26-26 is spaced throughout a major portion of the length thereof Patented July 16, 1957 vary the length of the table top 3 from the adjacent face of the panel 18 to provide a space for reception of the outer end portion of the leaf 17 in slidable engagement therewith. The outer margin of the panel 18 is slidably engageable with the channel 24 on the rail 23. The panels 16 and 18. are connected. together at the outer ends of their longitudinal edges by hinges 32.

Mounted on the outer margin of each of the panels-16 adjacent the inner end thereof is a guide yoke 33 which extends astride the margins of the panels -16. as particularly shown inFig. 11, one leg a. of the yoke 33 being affixed to the panel 16 as by a rivet. I) while the other leg c of the yoke projects beneath the panel 15 in slidable contact therewith. Similarly a. guide, yoke 34 having one leg d thereof affixed to the rail 26. extends between th adjacent margins of the panel 16 and leaf 18, and has its other leg e overlying the inner margin of the panel 16 in slidable relation thereto as particularly shown in Fig. 10. The yokes 33 and 34 serve to retain the outer end portions of the panels 16 and 15 in close sliding relation to each other.

In similar fashion a guideyoke 35 carried on the inner end of the rail extends between the adjacent margins of the panel 16 and 18 with one leg 1 thereof overlying the outer face of the panel 18, the yoke spanning the inner margins of the leaves 17 and 18 and serving to retain such margins in close sliding relation to each other, as particularly shown in Fig. 10.

Each of the end extensions B is fitted with a vertically adjustable support C which support is here shown as embodying a pair of legs 36-37 pivotally mounted at their upper ends on the outer end portions of a shaft 38 extending beneath the rails 26-26 transversely thereof and carried in bearings 39 mounted on the latter, the legs 36-37 being designed for positioning at various angular relations to the table top so as to support the latter at a selected level or height relative to the floor on which the legs are seated.

As a means for holding the legs 36-37 in various angular relations to the table top a brace D is provided having its lower end pivotally connected to the legs 36-37 and having its upper end portion engageable with the rails 26-26 at various points along the lengths of the outer end portions thereof. As here shown the brace D comprises a pair of cross arms 40 and 41 pivotally connected together intermediate their ends by a pivot 42 and having their lower ends connected to pivot pins 43-43 mounted on the lower end portions of the legs 36-37.

The upper ends of the arm 40 and 41 are fitted with axially aligned studs 44-45 which project outwardly from the arms for positioning beneath the rails 26-26, the studs 44-45 being designed to be connected to the rails 26-26 at various points along the lengths thereof; the rails being here shown as formed with a series of transverse notches 46 adapted to receive the studs 44-45. The upper ends of the arms 40 and 41 are formed to abut against the inner faces of the rails 26-26, while the lower ends of the arms are formed to abut against the inner faces of the legs 36-37 when the arms are in their extended rail engaging position as shown in Fig. 6.

The studs 44 are elongated so that when seated in the notches 46 in the rail 26 their outer end portions will underlie and form an abutment for the rails 30 on the table leaves to limit downward swinging movement of the latter and aiford a support therefor when the leaves are disposed coplanar with the table top.

The lower end portions of the arms 39-49 are connected together by a spreader E comprising a pair of toggle links 47-48 interconnected by a pivot 49 and having their outer ends connected to the arms 39-40. by pivots 59 in the manner common'in rule joint connections. The links 47-48 serve when in their extended positions as a means for spreading the arms 39-40 and holding them in their spread position.

The arm 40 is formed of a length exceeding that of the arm 39 whereby on spreading the arms 39 and 40 rela tive to each other the leg 37 engaged thereby will be thrust laterally to an outwardly inclined position, the pivotal mounting of the legs 40 being sufiiciently loose to permit such lateral movement thereof. By this arrangement the legs 40 will serve as diagonal struts to stabilize the table and also serve to oppose tilting of the table under loads imposed on the leaves thereof.

At the outer end of the extension B a spacer panel 18 underlies the panel 18 and is interposed between the latter and the rail 30, being seated on the latter to space the inner end portion of the panel 18 from the top of the rail 30. The opposite margin of the panel 18 is engaged by a molding 23 which is positioned astride the outer margins of the panels 18 and 18 and is rigidly aflixed thereto.

In assemblying the end extensions B on the intermediate table top A, the ends of the panels 15 and leaves 17 of the latter are inserted in the open ends of the slots 28, and in the space between rail 30 and the leaf 18, so as to position the panels 16 and leaves 18 on top of the panels 15 and leaves 17 respectively. The yokes 33, 34 and 35 will then be positioned astride the margins of' the panels 15-16 and the inner margins of the leaves 17-18. On advancing the panels 16 and leaves 18 over the panel 15 and leaves 17 the outer ends of the rails 19-19 and 21 are slidably engaged respectively with the rails 26-26 and 30 on the end extensions B. while the outer margins of the leaves 18 will be slidably engaged with the channel 24 on the rail 23 extending along the outer margin of the leaf 17. The end sections B may then be advanced on the intermediate section A until their inner ends abut as shown in Fig. l. The end panels 16 and leaves 18 will then overlie the panel 15 and leaf 17 On completion of the assemblage above described stops are provided at 51 on the rail 19 which project into retractive movement of the yokes 34 so as to limit outward movement of the extensions and prevent their accidental withdrawal from engagement with the intermediate section, the stops 51 consisting of screws applied to the rail 19 so that the heads thereof will form abutments.

When the table is assembled, the leaf portion thereof comprising the relatively sliding leaves 17 and 13-18 may be swung on the hinges 25 and 32 between a position extending coplanar with the table top panels 15 and 16-16, to a position overlying the latter as shown in dotted lines in Fig. 4.

The table is especially designed for positioning in the space extending between the back of the front seat F of an automobile and the front of the back seat G thereof as shown in Fig. 5. The adjustable leg structure C permits of varying the height of the table top, if need be, so that the upper face of the table top will extend on a plane with the forward edge of the seat G against which the overhanging forward edge of the table top substantially abuts. The leaf portion of the table top is swung from its folded position so that its outer margin formed by the rail 23-23 will abut the seat back P so as to close the gap extending between the table top proper and the back of the front seat. is formed of a width exceeding the ordinary width of such gap so that when the outer margin of the leaf is brought into contact with the back of the front seat the leaf will come to rest in an upwardly inclined position which will vary according to the spacing of the seat F'and G and which may vary in different models of automobiles. In this fashion the table is accommodated to various widths of such spacing and by reason of the end extensions is adjustable longitudinally to fit various lengths of seats. Manifestly the table may be utilized as such apart from an automobile in which event the leaf portion thereof will be extended horizontally as shown in full lines in Fig. 4.

When not in use the table may be folded into a compact package by retracting the end extensions 13 to their innermost positions, disposing the leaf assembly in its folded position and folding the legs against the under side The leaf portion of the tableof the table on disengaging the upper end of the brace D and swinging it to a folded position overlying the under side of the table top.
