10 Claims. (Cl. 311-32) This invention relates to an improved collapsible table.

One of the objects of the invention is to provide a table suitable for use either outdoors or indoors, wherein, when used outdoors, the table will provide an attractive and convenient article of so-called yard furniture suitable, among other uses, to be employed as a support for an umbrella sunshade, and wherein, when used indoors, the table will, among other uses, provide a convenient and stable support for a Christmas tree.

Another object of the invention is to provide a table embodying a stand for supporting the table top, wherein the legs of the stand may be adjusted in length to vary the height of the table, and wherein thetable top may be detached from the stand and compactly folded.

And a still further object of the invention is to provide a table wherein the table top may, when so desired, be rotated upon the stand, wherein the table top may be easily locked frictionally in any position of rotated adjust ment solidly stationary upon the stand, and wherein the table top may be easily released when it is desired to either rotate the tabletop or remove the table top from the stand.

Other and incidental objects will appear during the following description of the invention, and in the drawmgs:

Figure 1 is a side elevation of my improved table.

Figure 2 is a side elevation showing the table used to support a Christmas tree.

Figure 3 is a side elevation showing the table used to support an umbrella sunshade.

Figure 4 is a bottom plan view of the table.

Figure 5 is an enlarged, detail, vertical section through the head of the stand of the table.

Figure 6 is a fragmentary side elevation showing the top plate of the head loosened.

Figure 7 is a fragmentary perspective view particularly showing the cam collar of the top plate of the head of the stand.

Figure 8 is a detail sectional view showing one of the hinges employed between companion sections of the table top.

Figure 9 is a perspective view showing companion sections of the table top folded.

Figure 10 is a perspective view showing the stand collapsed and without the table top.

In carrying the invention into effect, I employ a stand which, as best seen in Figure 5 of the drawings, is provided with a circular head 9 comprising a bottom plate 2,782,085 Patented v Feb. 129, 195

the bead 16, so that the two beads are staggered with respect to each other.

At its lower end, the sleeve 12 is formed with a sinuous lower edge to provide diametrically disposed cam faces 18, at a right angle to which are oppositely disposed depressions 19. Removably pinned or otherwise fixed to the lower end of the stem 14 of the top plate 13 is a collar 20 which is provided with oppositely disposed camfaces 21, and, at a right angle to the cam faces 21, with oppositely disposed depressions 22. Thus, as will be seen, when the top plate is rotated in one direction to dispose the cam faces 21 of the collar 20 beneath the cam faces 18 of the sleeve 12, the top plate will, as seen in Figure 5 of the drawings, be wedged downwardly toward the hub 11 of the bottom plate 10 and thus tightened, while, when the top plate 13is rotated in the opposite direction, the cam faces 21 of the collar will, as seen in Figure 6 of the drawings, be received in the depressions 19 and the cam faces 18 of the sleeve in the depressions 22 of the collar, so that the top plate 13 will be freed for limited upward axial movement and thus loosened.

Swingingly connected to the bottom plate 10 of the head 9 of the stand are equidistantly spaced legs 23, preferably three in number. Each of these legs is composed of overlapping upper and lower sections 24 and 25 respectively, and connecting the upper sections to the plate 10 are suitable hinges 26. Formed in the sections are elongated slots 27 which more or less freely receive bolts 28 slidably connecting the sections with each other, and, preferably, the bolts are provided with wing nuts 29, so that, as will be understood, the lower sections of the legs may be readily adjusted upon the upper sections thereof for varying the length of the legs. Fixed to the side edges of the upper sections 24 near their lower ends are guide plates 30 embracing the side edges of the lower sections 25, and fixed to the side edges of the lower sections near their upper ends are like guide plates 31 embracing the side edges of the upper sections. These guide plates will accordingly maintain the sections 24 and 25 of the legs in registering alignment.

Fixed at their ends to the lower side of the bottom plate 10 of the head 9 of the stand is a pair of U-shaped straps 32 which straddle the sleeve 12 of said plate and are crossed at a right angle to each other to provide a socket 33 at the lower end of the stem 14 of the plate 13 of said head. Extending through the straps 32 at their intersection is a depending rod 34, and slidable upon said rod is a sleeve 35 which carries a set screw 36 for securing the sleeve in adjusted position along the rod. The sleeve 35 is provided with ears 37, while at points near their lower ends the upper sections 24 of the legs 23 carry hinge plates 38, and pivotally connected to said ears and to said plates are links 39. As will be perceived, the sleeve 35 may thus be adjusted along the rod 34 for adjustably spreading the legs 23 of the stand and securing the legs in adjusted position.

Removably supported by the stand, as described in the foregoing, is a preferably circular table top 40. This table top is composed of four sector-shaped sections hinged together in pairs, the sections of one pair being indicated at 41 and 42 respectively, and the sections of the other pair at 43 and 44 respectively. Each pair of 10 on which is formed a hub 11, and depending from plate is provided with a like bead 17 of less diameter than sections thus forms half of the table top. Fixed to the under side of each pair of sections of the table top at their radial lines of hinged connection are pairs of mating reinforcing cleats 45, and mounted upon each pair of cleats are spaced hinges 46. These hinges are all alike, and, accordingly, only a single hinge need be described;

in detail.

As best seen in Figure 8 of the drawings, the cleats 45 are provided at each hinge 46 with a pair of oppositely disposed slots 47, and fixed to the lower faces of said;

cleats are like angle-shaped hinge plates 48 having wings 49 and 50 respectively which extend into said slots. The wings are provided with like longitudinal slots 51 and 52 respectively, and pivoted at one end'to the upper .end

of the wing 4-9 is an arcuate hingelinkxSS, to the free end of which is fixed a stud'54'slidable in the slot 51 of the wing 50. Pivoted'at one endto the upper end of the wing 50 is a like mating hinge link 55, to the free end of which is fixed a stud56 slidablein the slot 52 of the wing 49, and pivotally connecting the links with each other is a pintle 57.

Figure 9 of the drawings shows a pair of the sections of the table top 4%, say the sections Aland 42,. folded. As the sections are swung into aligned normal position, the pintlcs 57 of the hinges46 of the sections will act on the links 53 and 55 to shift the studs 54 and 56 toward the outer ends of the slots 51 and 52 of the wings 49 and 50, while the sections 41'and 42 of the table top will swing about said pintles into aligned mating position abutting at their meeting edges. Preferably, each pair of cleats 45 carries a pair of spaced, reversely presented, resilient guide clips 58 for directing the sections of each half of the table top into mating relation as well as eliminating any sagging between the parts.

Fixed to the under side of the sections 41 and 43 of the table top 49 at the radial line of separable connection therebetween is a pair of mating reinforcing cleats 59 and 60 respectively, while the sections 42 and 44 carry a like pair of cleats 61 and 62 respectively. Preferably, the cleats 6t} and 61 carry dowel pins 63 which removably fit in suitable sockets in the cleats 59 and 62, and secured to the several cleats are reversely presented, resilient guide clips 64 which serve the same purpose as the clips 58.

Secured-to the cleats 59 and 61 are catch plates 65, and mounted upon the cleats 6i) and 62 are pivoted angleshaped catch members 66 disposed to engage the plates 65. Connected-to the catch members 66 are hand rods 67 which extend toward the free edges of the sections 43 and 440i the table top and are thus easily accessible for operating said catch members. As will beseen, the catch members 66 will normally lock the two halves of the table top 40 solidly together.

his now to be noted, as best seen in Figure 9 of the drawings, that the tips of the several sections of the table top 40 are cut away along arcuate lines to fit the hub 11 of the bottom plate It of the head 9 of the stand, and, as seen in Figure 5, are received in the annular groove 15 between the peripheral margins of the plates and 13 to enact therewith. Consequently, when the top plate 13 is tightened, as previously described, the inner peripheral margin of the table top will be firmly clamped between said plates for solidly connecting the table top with the stand. Furthermore, as the plate 13 is tightened, the head 16 will tend to bite into the inner ends of the several cleats 45, 59, 61, and 62, while the bead 1'1 will tend to bite into the upper surface of the inner peripheral margin of the table top and exert a caating action thereonfor eliminating any looseness between the parts.

To assemble the table top as with the stand, companion sections of the table top, say the sections 41 and 42, are first swung into alignment and inserted in the groove of the head 9 of the stand, the top plate 33 of said head having been loosened, as previously described. The sections "33 and 54 the table top are then likewise aligned and inserted in said groove, when the two halves of the table top are locked together by the catch members 66. The top plate 13 is then tightened for binding the table top in position, when, if so desired, the legs 23 of the stand may be adjusted, as pre iously described, for either raising or lowering the level of the top of the table.

In connection with the installation of the table top 49,

it may be noted that after the top plate 13 of the head 9 of the stand has been manually rotated to fiictionally.

grip the table top, the table top itself may then be rotated manually for further turning the plate 13 until the top plate is tightened sufiiciently to lock the table top rotatively stationary. On the other hand, the table top may be counter-rotated manually to loosen the plate 13, when the table top may be freely turned to any rotated position of adjustment desired and again locked stationary.

As previously indicated, Figure 9 of the drawings shows the sections 41 and 42 of the table top 40 folded or collapsed, and, of course, the sections 43 and 44 of the table top may be folded in like manner. Figure 10 of the drawings shows the stand collapsed and without the table top.

In Figure 2 of the drawings, I have shown the table employed to support a Christmas tree. A Christmas tree holder is conventionally shown at 68, and a Christmas tree at 69. Any suitable means may be employed for securing the holder 62310 the table, and, if found appropriate, the head'9 of the stand may be provided with suitable openings for receiving fastening elements for the holder. The ment the table as a support for a Christmas tree has 7 been found particularlyadvantageous, since, as previously noted, the height of the table may be adjusted, while the tabletop' iti provides ample space for the arrangement of figurines and the like beneath the tree.

In Figure 3 of the drawings, I have shown the table employed to support an umbrella sunshade. A sunshade is conventionally shown at 70, and, as usual, the sunshade is provided with a. center pole 71. The lower end of the pole is inserted through the stem 14 of the top plate 13 of the head 9 of the stand to rest in the socket 33 provided by the crossed straps '32. The straps will thus sustain the weight of the sunshade, while the stem 14 will cooperate with said straps for maintaining the lower end of the pole 71 in upright position.
