4 Claims.

This invention relates to tables of the extension leaf type, and has for its main object to provide a table in which the extension member comprises two telescopic elements, the leaf proper and a tongue upon which the leaf is slidably guided, the tongue being slidably and pivotally connected to the table, the object of the pivotal connection being to permit the leaf to be drawn out endwise or swung to a sidewise position with respect to the table, the object of the tongue being to permit the entire area of the leaf to be extended beyond the periphery of the table top.

Other objects of the invention will appear as the following description of a preferred and practical embodiment thereof proceeds.

In the drawings which accompany and form a part of the following specification, and throughout the several figures of which the same characters of reference have been employed to designate identical parts:

Figure 1 is a perspective view of a table embodying the principles of the invention;

Figure 2 is a longitudinal section taken just below the plane of the bottom of the drawers, with the leaf in contracted position;

Figure 3 is a similar view showing, the leaf extended and swung to one of its sidewise positions;

Figure 4 is a cross-section taken along the line 4 4 of Figure 2;

Figure 5 is a longitudinal vertical section taken along the line 5-5 of Figure 2;

Figure 6 is a perspective view of a modified form of the invention, in which the extensible leaf forms the table top;

Figure 7 is a similar View showing the top extended and swung to one side of the table, exposing the individual lids of underlying compartments;

Figure 8 is a vertical cross-section through the table shown in Figure 7, with the parts in closed position;

Figure 9 is a perspective view of still another modification of the invention;

Figure 10 is a longitudinal section taken just below the table top;

Figure 1l is a detail in perspective, showing the slide and guide connection between the elements of the extension member;

Figure 12 is a longitudinally Vertical section through the slot, taken alongv the line I2-I2 of Figure 3; and

Figure 13 is a broken persp-ective view showing the slot.

Referring now in detail to the several figures, and rst adverting to that form of the invention shown in the group of Figures 1 to 5, the numerals I represent the legs of the table, deining a stable base of support therefor, and supporting the horizontal table top 2 at their upper ends.

At an intermediate point, near the top, the legs also support a transverse member 3 which is spaced from and substantially parallel to the table top.

Figure 3 shows that the transverse member 3 is provided intermediate the sides of the table with a longitudinal slot 4. The extension member which as a whole is designated by the reference character 5, consists essentially of two relatively movable members, a tongue B and the leaf l. The tongue and leaf are telescopically interconnected by means of the slides 8, secured to the opposite parallel sides of the tongue as shown in Figure 11, which cooperate with the guide tracks 9 secured in parallel relation to the under side of the leaf 'I. The tracks 9 are formed with inwardly directed flanges I0 which overlie the slides 8 and define the relative movement between the tongue and leaf to sliding movement in a single plane.

The tongue 6 is pivotally mounted with respect to the slot 4 by a pivot pin or bolt I I which itself is slidable in the slot 4 and also slidable in a slot I2 formed in the tongue 6 extending longitudinally thereof and parallel to the opposite sides of said tongue. Thus, the tongue 6 is capable of a compound swinging or sliding movement with respect to the transverse member 3. The pivot pin II has an enlarged head and washer I3, as shown in Figure 4, engaging the sides of the slot 4 on the under side of the transverse member 3, by means of which the pivot pin is retained in the slot 4.

By the construction as above described, the extension member 5 may be drawn out endwise from the end I4 of the table, or it may be canted while still beneath the table top to the oblique position indicated by the reference character I5 in Figure 2, so that it can be swung and eX- tended sidewise with respect to the table into the full line position shown in Figure 3 on either side of the table. The slot, as shown, has sides which taper toward one another in a depth direction and is deeper at one end than at the other, forming an inclined track 28 with which the head 29 of the bolt II cooperates, so that when the extension member is drawn out the bolt head rides upwardly along the inclined track 23, finally clamping the extension member rigidly against the slotted transverse member when the tongue portion of the extension member is in extended position.

Figure 1 shows that the table is provided with hingedly depending perimetrical flaps I6 enclosing the space intersected by the plane of the extension member 5. If the leaf l is made of the maximum size which will pass endwise through the space I'I at one end of the table,

its corners I8 when in the canted position shown in Figure 2 will protrude beyond the periphery of the table, engaging the flaps I6 and pushing them outward so as to accommodate the movement of said corners. When the leaf 1 is in any one of its extended positions, one of which being shown in Figure 1, all of the flaps I6 will close excepting only the one on the side or end from which the leaf is extended.

Figures l and 4 show the table provided with drawers or compartments I9 positioned below the table top and above the extension member.

Referring now to that form of the invention shown in Figures 9 and 10, the table is provided with pairs of legs 20 and 2l at opposite ends, the pair of legsv 2i) being shorter than the legs 2|. The transverse member 22 lrests horizontally uponV the legs 2liV and is secured to the legs 2l at an appropriate distance below their upper ends. The table top Z3 is supported upon the upper ends of the longer legs 2l iny aposition substantially parallel to the transverse member 2-2. The difference between the lengths of the pairs of legs provides the space 23 between the top and the transverse member, between which the extension member 5 is mounted. The construction of the extension memberis the same as that describedv in connection with the form of invention shown in Figures 1 to 5, merely adding a transverse batten secured to the tongue 6 and extending at its opposite end slightly beyond the sides of the leaf? and having the handle knobs 2l". It is obvious from Figure 9 that the leaf'T can be extended rectilinearly through the open space at one end ofthe table, or swung and extended laterally from the said space, at either side of the table. In order to provide additional support between the top 23 and the transverse member 22, the table is Iprovided with side members 211 and an end member 25, arranged perimetrically about that part ofthe table beyeond the range of extension of the leaf '5, adding strength as well as attractive finish to the table.

In this form of the invention as well as that embodying the other modifications, the edge portions of the table, both endwise and laterally, upon which the tongue or leaf is adapted tov rest when extended, are at a slightly higher elevation than the plane of contact between theV tongue and the slotted member adjacent the pivot. This provides that the extension member shall slope very slightly upwardly in a direction away from its pivotal connection. This slightly upward tilt is designed to compensater for, and to counteract the sag which is inherent in any telescopic structure, due to looseness at the junctures of the several parts.

In that form of the invention shown in Figures 6 to 8, inclusive, a simplified construction is shown, in which the table top itself is the extensible leaf. The table comprises a box-like structure supported at the top of the legs comprising the side and end members 28 and 29 with a bottom 36 and intermediate vertical partitions 3l and 32, the latter forming a plurality of compartments, of which the member 33 forms the common bottom. Said compartments are closed by the hinged lids 33.

|Ihe longitudinal partition 3| is formed with a longitudinal slot 34 constructed to receive and retain the pivot pin il of the tongue 6 ofthe extension member 5. The leaf portion 1 of said extension member is slidably mounted upon the tongue in any suitable manner, as for example by the means shown in Figure 8, comprising overhanging tracks 35 which engage the under sides of the projecting ledges 36 formed on the sides of the tongue member. Inasmuch as the extension member in this form of the invention is unimpeded in its capacity to swing through an angle of 360, itis unnecessary that the pivot Il shall be slidable relative to the tongue 6. The leaf 'l is made of such size as to completely cover the table and preferably to project beyond the area defined by the legs, forming the top of the table. When in extended position, the leaf may rest against either the side or end of the table, selectively exposing cer-tain of the underlying compartments.

It will be understood fromr the above description that I have disclosed a number of modications of my invention, all of which are built upon a common novel inventive concept. It will be understood to those skilled in the art that the specific details of construction and the arrangement of parts as described are by way of example, and not to be construed as limiting the scope of the invention which is defined in the appended claims.

What I claim as my invention is:

1. An extensionV leaf table comprising means forming a base of support, a transverse member supported by said base having a longitudinal slot, and a swinging extension member comprising a tongue slidably and swingably mounted on a pivot slidably retained in said slot, a leaf telescopically slidable upon said tongue, and cooperating slide and guide means between said tongue and leaf restricting said members to rectilinear relative movement in a single plane.
