UMBRELLA TABLE AND UMBRELLA ENGAGING MEANS THEREFOR Filed Oct. 9, 1952 TNVENTOR WILLIAM H. WH EELER ATTORNEY United States Patent UMBRELLA TABLES AND UMBRELLA ENGAGING MEANS THEREFOR This invention relates to umbrella tables adapted for use with umbrellas on beaches, lawns, terraces and in other places to provide shadedenvironments. More particularly, the invention relates to tables of the character described, wherein an elongated table top is provided within one end portion thereof with means for receiving an umbrella pole in amanner to form of the remainder of said table an unobstructedtable surface-of "substantially greater length than width.

It has been customaryin the past to support-umbrellas of the type-adapted to provide shade on beaches, lawns, terraces and the like by means Off tables of various types and kinds, having acentral well. or supporting means-for receiving an umbrella pole. Tables-of this type are generally quite heavy, particularly in the base construction thereof, in order to provide adequate support for an umbrella and the usable area or surface-thereofisgreatly restricted by reasfonof the centralwell or umbrella: supportingmeans. In addition,: the, umbrella pole is a constant barrier and annoyance to persons sitting-in diametrically opposed positions around the table.

An object of my invention" istoprovide anew and i improved umbrella table wherein the umbrella engaging means is offset with respecttoarr elongated usablev table surface whereby a number of people canbe seated around an unobstructed table surface suflicientlylarge to permit comfortable eating, card playing and the like. A further object of the inventionis to provide an umbrellatable having'an elongated unobstructed-table surfacewhich can be readily oriented circumferentiallywith respect to an umbrella engaged thereby to facilitate maximum utilizationof the shade produced-by'said umbrella',,a still further object or the invention being; to provide means for adjustably supporting the umbrella" and table irrassembled position.

These and other objects oi? my invention will heapparentfrom a' consideration-of the following description together with the a'ccornpanyingdi'awing: in whichcertain' embodiments of my inventionare illustrated, in which the various parts thereofare identified by suitable reference charact'ersin each of the views and in which:

2,743,146 1C6 Patented Apr. 24, 1956 Fig. 5 is a-partial plan viewofthe-table-and supporting means as shownin Fig. 4'.

In Figs.-1 and 2 of the-drawing I have shown at 10 one formofumbrella table in accordance with the present invention-,1ascomprising an: elongated table top 1 -1 having means at-one' end 12' thereof as indicated by the" folding legs 13' for supporting said end of the table in an elevated position; and an aperture or cut-out portion 14: centrally ofi the other end 15 of the table: for'receivingithepole 16 of a: conventional-umbrella 17', For purpose of illustration the umbrella pole has been shown at-16" aspiercin'g or penetrating a supporting, surface in the manner en's"- tomary in the erectionofbeach umbrellas and the' like. It isto be understood, however, that the construction-as shown in Figs. 1 and 2 is adaptablefor use many instance where anumbrella is supported in the-vertical position either by penetration of the pole into-the ground or by engagement with a supporting: base, conventional type of umbrella table, or the like.

Orientation of the end 15nof the table top'vertically with respectto the umbrella-pole 16- is providedby means oi a sleeve or'bushing 18-slidably engaging the pole'1 6 and preferably having an enlarged bearing plate 19 for can tacting the under surface of the table top. Means as indicated by the clamp screw 20 is: provided for securing the bushing 18 tothe umbrella' polein' any desired'ventical position of; adjustment. It should be noted in this connection that the bushing; 18 and plate-19 can' constitute aseparate unitary member independent of both: the table and pole or, ifdesire'dt can be secured tothe: table and movable therewith. Itwill further be noted that thetable 10 having the aperture or cut-out 1'4 therein can constitute a separate and complete article" of manufactu're as, forexample, if it is desired to utilizethe table 10 in conjunction with an umbrella table' of the'conventional type above'rnentionedi Any conventional type of umbrella can" be employed in my new umbrella table'and in particular it should be noted that the umbrella or canopy 21 maybe mounted onza rigid pole: or canbe mounted on asectional pole havingtan adjustable pivot as iridicated att22 to per'mit the swinging of the canopy intodiff'erent angularpo'sitions as indicated, for example, by'thedot and dash line showing 21" in Fig: 1 of the drawing; The tiltable umbrella would have the" advantage of providing a greater effective area for blocking out the slan'tingrays' of the" sun; as will be noted inFig, l of the drawing; but with-either typeo'f umbrella it will be apparent that theelo'ngated t'able con- "st'ruction permitsmaximum utilization of the shadow cast by the'umbrella.

In Fig; 2' of the drawing four ch'a'irs 23 have; been diagrammatically indicated in a typical relationshipwith theelongated table inorder to give a clear indica'tion of the extent to which my table provides an unobstructed ii'sable surface. In'this connection it will be noted that' as the position of the sun'changes to alter the direction of the shadow cast by the umbrella thetable 10 can be swung about the umbrella pole 16 so that the elongated portion of the table extends from the umbrella pole in a direction substantially opposed to the" position} of the sun;

In Fig. 3 or the drawing I have shown a=portion 0a table top 24 and an umbrella pole 25 generally correspending with the table top 11 and umbrella pole 1.6 as shown in Figs, 1 and 2 of the drawing. In place of the'aperture1'4'inthe table topas shown in Figs. 1 and-2,

howevenl have indicated an elongated slot 26 whichis end 32 of which is adapted to directly engage the umbrella pole 25 in securing the bushing 28in different positions of adjustment on the umbrella pole.

At 33 I have indicated a circumferential bearing plate arranged on the bushing 28 and adapted to engage the lower surface of the table top 24. The bearing plate 33 can be integral with the bushing 28, or if desired, can comprise a separate washer-like part fitting around the threaded shank 27 of the bushing. A second bearing plate 34 having an aperture 35 therein for freely engaging thethreaded shank 27 is adapted to engage the upper surface of the table top 24, and an internally threaded clamp nut 36 engaging the threaded shank 27 provides means for drawing together the bushing 28 and the

hearing plates

33 and 34 to provide a rigid support between the umbrella pole 25 and the table top 24.

The clamping engagement thus provided between the tabletop 24 and umbrella pole 25 permits the umbrella pole to be utilized effectively as a supporting leg for the table, and imparts to the assemblage greater rigidity than is provided by the loose bearing engagement between the table top 11 and bushing 18 as shown in Figs. 1 and 2 of the drawing. At the same time, it will be apparent that the effective area of the table top 24 can be readily altered by merely loosening the clamp nut 36 and sliding the table top 24 to advance the bushing shank 27 to a different position in the elongated groove or aperture 26 in the table top. Loosening the clamp nut 36'will also permit free rotation of the table top 24 about the bearing shank 27 and umbrella pole supported therein. In this way, the table can be reoriented with respect to the umbrella and the shadow cast thereby without the necessity of moving the umbrella pole 25 or any supplemental support which may be provided therefor.

In Figs. 4 and 5 of the drawing I have shown a further modification of my invention wherein an elongated table 37 having conventional legs 38, preferably of the foldable type, for supporting the same is provided with an adjustable umbrella supporting unit 39 adjacent one end 40 of the table for maintaining vertical alignment of an umbrella pole 41 passing through a slot 42 in the end 40 of said table top. The supporting unit 39 has been shown as comprising an enlargedbearing member 43 for engaging the under surface of the table top at the end 40 thereof and having a central hub portion 44. A plurality of angularly disposed brace members 45 extend from the periphery of the bearing 43 to a second hub or bushing 46 vertically spaced from the hub 44. The

hubs

44 and 46 are provided with vertical bores which receive an elongated tube 47 which is adapted to closely, but slidably,

engage the umbrella pole 41. Means is provided as indicated by the clamp screw 48 for clamping the tube 47 in a fixed position with respect to the bushing or hub 46.

The upper end 49 of the tube 47 extends above the upper surface of the table top 40 and has fixedly secured thereto an externally threaded sleeve 50 adapted to be engaged by internal threads of a clamp nut 51. Clamp nut 51 in turn engages a bearing plate or washer 52 which contacts the upper surface of the table top and as the clamp nut 51 is tightened on the threaded sleeve 50, the bearing member 43 and the bearing member or washer 52 are brought into close engagement with the opposed surfaces of the table top to rigidly mount the umbrella supporting unit 39 thereon.

The umbrella supporting unit 39 when assembled as above described provides an elongated vertical guide for the umbrella pole 41 which rigidly supports the umbrella pole in a vertical position, but it will be noted that since the umbrella pole is slidable in the tube 47, reorientation of the table can be effected by merely raising the table and pivoting it around the umbrella pole, the primary support for the weight of the umbrella being borne by the umbrella pole 41. The lower end of the umbrella pole 41 may rest directly upon the ground or other sur face supporting the table, but is preferably arranged in a socket 53 of a separate foot member 54 which may be of suitable heavy material, such as concrete, cast iron or the like and which is preferably provided with a lower surface 55 of rubber or other suitable anti-skid material. The foot member 54 is not essential, but is desirable both to prevent damage to the table supporting surface by the umbrella pole and also to provide a supplemental support for maintaining the vertical alignment of the umbrella pole. I

In Figs. 4 and 5 of the drawing the groove 42 for receiving the umbrella pole and supports therefor has been shown as extending through the end 40 of the table, In this way the umbrella pole may be supported in different positions longitudinally of the table, the clamping engagement provided by the bearing member 43 and washer 52 imparting rigidly to the split end 40 of the table. By merely loosening the clamp nut 51 it will be noted that the umbrella supporting unit 39 can he slid outwardly of the table through the end 40 thereof to permit detachment of the table and supporting unit for purposes of storage and the like. It will be understood, however, that the supporting unit 39 can be employed equally well with a table having only a circular aperture, such as the aperture 14 as shown in Figs. 1 and 2, or the elongated aperture, such as the aperture or slot 26 shown in Fig. 3 of the drawing.

It will also be noted that the supporting unit 39 can be modified by fashioning the hub 44 thereof similar to the bushing 28 as shown in Fig. 3 and providing in the hub 44 and bushing 46, central bores adapted to closely engage the umbrella pole 41. In this event, the tube 47 and the clamping means 48 can be dispensed with and the clamping engagement between the modified hub 44 and the clamp nut 51 would correspond identically with the clamping engagement between the bushing 28 and clamp nut 36 as shown in Fig. 3 of the drawing.

It will be noted that the various adaptations of my umbrella table do not require special umbrellas or umbrella poles, but can be used with conventional devices which are readily available. It will also be understood that the tables can be constructed from wood, metal, plastics, or combinations thereof to produce articles for different types of use. When portability is a factor, as for example with tables intended for beach use, it is within the scope of my invention to provide suitable jointed or hinged means intermediate the ends of the table top to permit the collapsing or folding of the table top into a portable unit of relatively small dimensions. More elaborate tables made in accordance with my invention can, if desired, be provided with means for adjusting the length of one or more of the legs thereof in order to facilitate adjusting the table for firm and level support on irregular ground and the like.

While I have indicated wing-bolts as the

adjustable clamp devices

20, 31 and 48 for engaging respectively the

poles

16 and 25 and the tube 47, it is to be understood that these are merely illustrative and that I can employ any conventional means for preventing relative movement of telescopically arranged parts. Similarly the

clamp nuts

36 and 51 are merely illustrative, and any conventional clamping means can be employed in supporting the bearing members in firm engagement with opposed sur faces of the table top.

As previously mentioned the table 10 as shown in Figs. 1 and 2 can constitute a complete article for manufacture and sale, as for example, when it is intended to utilize the table in conjunction with a conventional umbrella table. Similarly the table 37 as shown in Figs. 4 and 5 can constitute a complete article for manufacture and sale, as for example, when it is intended to utilize the table in conjunction with an umbrella which is independently supported in the vertical position. In such instances the table can be freely moved with respect to the fixed umbrella pole in providing the rotary adjustment or orientation herein contemplated. The cut out portion of the table end 40 can be in the form of a circular aperture as shown in Figs. 1 and 2, an elongated aperture as shown in Fig. 3, or a slot extending through the table end as shown in Figs. 4 and 5. When the slot extends through the table end it will be understood that the table, with legs extended, can be positioned under an umbrella having independent means for vertical support by merely aligning the slot 42 with the umbrelia pole and moving the table longitudinally until the umbrella pole is in the desired position within said slot.

Various changes and modifications in the table structures herein disclosed will occur to those skilled in the art, and to the extent that such changes and modifications are embraced by the appended claims, it is to be understood that they constitute part of my invention.
