3 Claims. (01. 311-403) The present invention relates broadly to supports for articles, and more particularly to dual adaptability tray attachments which may be demountably secured to either a side or a corner of a table top, for example, to support objects for the convenience of those using the table.
It is a common experience for those sitting at a table, particularly a card table, not to have room enough on the table top for all objects which it is desired to place there. Many persons smoke or have refreshments while playing cards, for example, but it is well known that where the playing surface must support not only cards but also ash trays, refreshments, etc., conditions may become crowded, dealing is difficult, glasses may be upset, and ash trays are frequently moved to get them out of the immediate way. In another aspect, tables are used for supporting dishes of food to be served buffet style, and it is a common experience for such dishes to require more surface than the top of a given table can provide. Card tables are often used for such purposes, but they offer a limited dish supporting area. In a still further aspect, tables of any type are not infrequently used under such conditions that they are crowded no matter how large their tops may be, and an example here is where papers are spread out on a table top. An ash tray or glasses may be in the way, even though the table per se can be said to have an extensive surface area.
To alleviate the above situations, i. e., to afford more supporting area in connection with the use of tables, for example, it is the principal object of the present invention to provide a tray attachment which may be demountably secured to either a side or a corner of a table top, thereby enabling the users to place on the attachment articles such as ash trays, cigarettes, refreshments, etc., where they will be out of the way and off the table but nonetheless readily accessible for use. It is to be particularly noted that any single given embodiment of the present invention thus has a dual adaptability, in that it may be secured to either a side or a corner of a table top.
It is a further object of the present invention to provide a tray attachment, of the type described in the immediately preceding paragraph, the article-supporting area of which is sufficiently low so that the construction may be used as a food or dish holder at which a child may sit without there being any necessity of elevating the height of his chair seat, as by books, cushions, or the like. Children may thus sit at the regular table used by their elders, but have their food 2 dishes supported at a lower level for their convenience,
To the accomplishment of these objects and of such others as appear hereinafter, the various features of the present invention reside in various constructions, combinations, and arrangements of parts, all fully described in this specification and then set forth in the appended claims which possess advantages readily apparent to those skilled in the art.
The various features of the present invention will be readily understood from reading this specification in connection with the accompanying drawing which illustrates the best physical embodiment of the invention at present devised by the inventor and in which:
Fig. 1 is a view in plan of an embodiment of the present invention, the clamping members being shown in the position they occupy, preferably, when the embodiment is fitted to a corner of a table top; r
Fig. 2 is a view in underside plan of the embodiment shown in Fig. 1;
Fig. 3 is an enlarged view in left side elevation of the same embodiment of the present invention;
Fig. 4 is an enlarged view in rear elevation; and
Fig. 5 is a detail view in underside plan corresponding to Fig. 2 but showing the clamping members in the position they occupy, preferably, when the embodiment is fitted to a side of a table top.
With reference to the drawing, the embodiment of the present invention there shown is provided with an article-supporting area part I0 which is substantially circular throughout the major portion of its extent but which may have any other suitable peripheral configuration. The top surface of the area It! is illustrated as being planiform, and for about 260 is frontally provided with a bead II to prevent movement of articles off the area. Upstanding from the rear portion of the area In is a wall structure indicated generally at [2, which wall structure has a number of 'rear planiform and curved faces which will be described and which permit embodiments of the present invention to function in association with the corners and sides of table tops.
The wall I2 is provided rearwardly with a pair of spaced co-planar faces I3 and M, the plane of which is at substantially to the upper surface of the area l0. Between and forwardly of the faces l3 and [4 there are located forwardly con-r verging faces I and I6 to form a forwardly converging V-shaped recess IT. The faces I5 and I6 are disposed at substantially 90 to each other and to the upper surface of the area I0, and with this construction it will be seen that the faces I5 and I6 are each at substantially 45 to the plane of the co-planar faces I3 and I4. JOil'liIL; the rear ends of the faces I5 and I6 and the inner ends, respectively, of the co-planar faces I3 and I4 are two forwardly extending, vertically disposed, and rearwardly open cylindrical sur-- faces IB and I9, respectively, which are located adjacent the respective sides of the recess I'I and form guideways for the vertical and lateral movement of the forward ends of clamping members, as will be described.
The structural elements above referred to are further provided with a lip 20 which extends rearwardly from the front and top of the wall structure I2 so as to overlie the co-planar wall rear faces I3 and I4, the forwardly converging wall rear faces I5 and it which together form the forwardly converging recess IT, and also the cylindrical guideways i8 and Is, and as indicated in Fig. 3, the under face of the lip 20 is planiform and at substantially 90 to the co-planar rear faces I3 and I4 as well as to the faces of the V-shaped recess IT. The foregoing structure is completed by a curved vertical wall portion 2I and a corresponding curved vertical wall portion 22 which extend forwardly and downwardly from the outer ends of the co-planar rear faces l3 and id, respectively, and merge with the heading Ii.
By reason of the structure so far described, it will be seen that the illustrated embodiment of the present invention may be associated with the corner of a table top in such manner that the under face of the lip 20 may engage the upper surface of the table top flatwise while the faces I5 and I8 forming the recess II engage flatwise the adjacent side portions of a corner of the table top. This is possible without interference by the co-planar wall rear faces I3 and I4 because the loci of the cylindrical guideways I8 and I9 cause the surfaces I3 and I4 to be, respectively, spaced outwardly from the planes of the surfaces I5 and I6.
On the other hand, it will also be seen that by reason of the structure so far described, an embodiment of the present invention may be associated with a side of a table top in such manner that the under surface of the lip 29 may engage the upper surface of the table top flatwise while the coaplanar rear faces I3 and I l of the wall I2 engage fiatwise the side of a table top. This is possible without interference by the surfaces It and is forming the V-shaped recess 11 because these surfaces lie forwardly of theplane of the surfaces I3 and It by reason of the loci of the cylindrical guideways i8 and I9. It is thus apparent that while the lip 28 engages the top surface of the table at all times, as it were, the co-planar rear wall faces l3 and I4 do not engage the table top when it is engaged by the wall faces I5 and I6, and the faces I5 and it do not engage the table top when it is engaged by the co-planar faces I3 and I 4.
In order to secure the tray attachment above described demountably to a table top in either of the above corner or side positions, the present invention contemplates the use of clamping members which coact with the lip 29, and means for moving the clamping members both toward and away from the lip 20, i. e., into and out of engagement with the under surface of a table top while its upper surface is engaged by the lip.
To this end the cylindrical guideways I8 and I3 do not extend upwardly to the lip 20 but instead terminate short thereof to provide horizontal wall structures 23 and 24 (Figs. 3 and 4) which are of considerable thickness. In each of these thickened portions 23 and 25 there is formed centrally a vertical passage 25 for the rotative reception of an elongated screw 26. With particular reference to Fig. 4, each screw 26 is provided with a head or knob 21 which.is located above the lip 20, with a smooth portion 28 which is rotatably received in the passage 25 in each case, and with an integral threaded shank 29 which extends downwardly in the associated guideway I8 or I9 to a point near the bottom thereof. Threadedly mounted on each screw shank 29 and located in the associated guideway I8 or I9 is the rounded forward end of a clamping member 30, the rear end portion of wlnch is indicated at 3i and is elongated and extends rearwardly beyond the associated wall faces I3 and I5, or I4 and I6, and therefore extends beheath the lip '20. Each clamping member 3! is provided 'rearwardly with a cover 32 of any suitable soft material such as rubber, heavy fabric, or the like, which may frictionally engage the rear portion 3i of each clamping member.
Each screw 26 may be of integral construction, as shown, or the knob 2! may be non-rotatively applied to the portion 28, and the clamping members as are mounted on the screw shanks 29 so as to be supported thereby from the guideways I8 and I9 in positions of parallelism with the under surface of the lip 20. By reason of this screw 26 and clamping member '30 construction, there is an operative connection between each knob 2! and the associated clamping member 30, and from this it follows that by turning the knobs 21 inone direction the clamping members 30 may be moved away from the lip 29 to permit fitting the construction as a whole to a table top edge or corner and that upon turning the knobs 21 in the opposite direction the clamping members 30 may be moved toward the lip 20 and thus into engagement with the under surface of the table top to coact with the lip 26 to clamp the table top between them. The shelf construction as a whole may thus be 'demcuntably secured to a table top in a firm manner, the covers 32 preventing the clamping members from marrin'g the top by their grip.
The forward ends of the clamping members as are rounded in conformity with the cylindrical guideways I8 and It, and these forward ends comprise elements extending forwardly of the rear faces of the wall I2 and fitting the guideways snugly but with a sliding fit, thereby rendering it unnecessary to provide a support for the lower end of each screw shank 29 to steady it when the knobs 22 are turned to move the clamping members '38. But the forward ends of the clamping members so are also rounded for a different reason. In mounting an embodiment of the present invention upon a table top, it is desirable that the clamping members extend rearwardly at substantially to the edge face of the table top to which they are adjacent, and by the same token to the wall I2 rear faces which engage that table top edge face. Thus, when a, corner of a table top is engaged by the faces 15 and I6 forming the V-shaped recess iI, there being two table top edge faces in this s situation, the clamping members '38 are manually turned laterally so as to be located at substantially 90 to the wall rear faces I and I6, respectively, as indicated in Figs. 1 and 2. When, however, the co-planar wall rear faces l3 and I4 engage a side edge face of a table top, the clamping members are manually turned laterally so as to be at substantially 90 to the plane of the wall faces I3 and M, as indicated in Fig. 5. The cylindrical surfaces of the guideways I8 and I9 and the rounded and conforming forward ends of the clamping members 30 readily permit this lateral position varying movement, and it will be seen that the outermost ends of the guideways I8 and I9, i. e., the mergence loci of these ends with the innermost ends of the coplanar surfaces l3 and I4, function as stops to limit lateral movement of the clamping members 30 to the position shown in Fig. 5, while the innermost ends of the guideways i8 and I 9, i. e., the mergence loci of these ends with the rear ends of the wall surfaces I5 and I5, function as stops to limit the lateral movement of theclamping members 30 to the positions shown in Figs. 1 and 2. It will be apparent that upon turning the knobs 2'! the clamping members 30 will move toward or away from the lip 20 regardless of the lateral position of the members.
The top surface of the lip 20 and the bottom surface of the area ID are shown as planfiorm merely for illustrative purposes and not for purpose of any limitation as to the scope of the present invention. The same remarks apply in kind to the front surface of the wall I2 as a whole, for the general conformance of the front of the wall l2 to the respective rear faces thereof has been illustrated merely as an example of the kind of conformance that would usually be provided if the tray attachment as a whole, apart from the screws and clamping members, were manufactured by a molding operation. It will be apparent that embodiment of the present invention need not be molded, and that the front face of the wall I2 may have any contour desired.
The height of the wall I2 may be any practicable in View of the object of the present invention, but one satisfactory height has been found to be substantially three and one-half inches between the upper surface of the area part 10 and the under face of the lip 20. The I the tray attachment in a location out of the way of the top surface of the table, and at the same time permits a child to sit at the table, as at meal time, for example, with his food supported at a lower level than the upper surface of the table top, thus frequently rendering it unnecessary to place a pillow, large book, or the like on the childs chair seat as is often the casewhere a child is seated at the same dinner table'as his parents.
What is claimed as new is: 1. In combination in a tray attachment for tables: a part having an article-supporting area; a wall upstanding from a portion of said area and providedrearwardly with a pair of spaced co-planar surfaces engageable with a side of a table top, said wall also being provided rearwardly with a pair of surfaces forming a forwardly converging V-shaped recess located between said c-o-planar surfaces and engageable with the adjacent outer side portions of a corner of a table top when said co-planar surfaces are out of engagement with the table top, said wall also being provided adjacent each recess side with a rearwardly open and forwardly extending guideway surface located between the rear end of said recess side and the inner end of the adjacent co-planar surface; a lip extending rearwardly from the upper portion of said 1 wall and over the guideways for engagement with the upper surface of a table top when either said co-planar surfaces or said recess are in engagement with the table top; members engageable with the lower surface of a table top for coaction with said lip to clamp the tray attachment as a whole demountably to a table top, said members having portions extending from the guideways rearwardly of said wall and beneath said lip to effect said coaction and also having portions located in said guideways, respectively beneath the lip; and rotatable means for supporting said members from the guideways and moving said members toward and away from the lip.
