Abstract

The table is made with a solid undivided table top and is provided with leaves which are to be arranged peripherally of the tabletop. The leaves are of the draw-type and are contained under the main tabletop. Slidable bars are disposed under the main tabletop for sliding out to support the leaves. The leaves can be formed so as to fold over on themselves about a hinged joint. This invention relates to a table having an undivided tabletop with extensions of the draw-table-type.

sum 3 OF 3 INVENTOR HENRY F/L so BEATELSEN BY aw 7 i222 TABLE WITH EXTENSIONS An object of the invention is to provide a table which has an undivided table top, i.e., without a dividing groove, and which may be converted into a table having a larger table area by adding peripheral leaves thereto.

Another object of the invention is to provide a table with a frame which is aesthetically narrow and which includes mutually crossing extensions for permitting the addition of leaves to the table to increase the table surface.

The characteristic feature of the table according to the invention consists in that the extensions comprise a first type of sliding bars which are adapted for engagement with two different supporting lists placed in fixed connection with the frame, viz an outermost supporting list having a comparatively elevated lower side and an intermediate supporting list having a lower underside, and a second type of sliding bars adapted for engagement with a supporting list in fixed connection with the frame, the underside of this supporting list being lower than the two first-mentioned supporting lists. By virtue of this engagement, the extensions will not collide with one another. It is seen at a glance that, if a sliding bar of the first type engaged with only one supporting list the sliding bar would require a much greater breadth. This then would necessitate a much broader table frame which would make the table less appealing to the eye.

In one embodiment, the invention specifically relates to a circular table having an undivided table top which is characterized by having four extensions, mutually staggered by 90?, of the draw-table type, each comprising two one-eighth circle ring leaves placed upon one another whose smallest diameter is equal to the diameter of the undivided circular table top, the two one-eighth circle ring leaves placement side by side to form a quarter circle ring leaf.

It will be seen that a table constructed in this way in a simple fashion fulfills the object of constituting a circular table with no crosswise extending groove in the compact state which can be converted to a larger table which will still possess a circular shape.

According to the invention it is especially advantageous that the two one-eighth circle ring leaves are hingedly connected to one another along a common radially extending edge while the free radially extending edge of the lowermost leaf has a projection for supporting the free edge of the swingable neighboring leaf.

An obvious embodiment of the table construction consists in dividing the circle ring around the undivided circular table top in a number of parts differing from eight.

These and other objects and advantages of the invention will become more apparent from the following detailed description and appended claims taken in conjunction with the accompanying drawings in which:

FIG. 1 shows an embodiment of the table according to the invention seen from above, the four extensions of the table of the draw-table type being pulled completely out and one of the four swingable one-eighth circle ring leaves having been swung out,

FIG. 2 the uppermost part of the table of FIG. I seen in the direction of the arrow a,

FIG. 3 another embodiment of the subject matter of FIG. 2,

FIG. 4 an extension according to the invention seen from above, all leaves having been removed,

FIG. 5 the same seen in the direction of the arrow A of FIG.

FIG. 6 the same seen in the direction of the arrow B of FIG.

FIG. 7 a sketch of the leaf division in case of a square table according to the invention, and

FIGS. 8 and 9 two different sliding bar types in the extension according to FIGS. 4-6.

The table of FIGS. 1-3, which is supported by four legs 10 while the frame is not shown, has an undivided circular table top 11 having diameter d.

Four one-eighth circle ring leaves are mounted in the table frame in the manner of a draw-table arrangement. In addition,

LII

each leaf 12 has a one-eighth circle' ring leaf l3 placed thereon and hinged thereto along a common radially extending edge 21. The leaf unit constituting one lower leaf l2 and one upper leaf 13 is mounted under the table top 11 and can be pulled out of the table frame. The free edge 22 of each leaf 12 has a projection 32 for supporting the free edge 23 of the swingable neighboring leaf 13.

It is remarked that it is not indispensable that the leaves are connected in pairs by means of hinges. It is also conceivable that they are grooved so that they can be slid into one another or be placed inside one another.

The crucial point is that a table is obtained having an undivided table top in the most compact state of the table, for instance a circular table having the diameter d, and that the table can be made larger, i.e., in the case of a circular table, such circular table having diameter D, the circular form being retained.

It will be understood that the table according to the invention will not need to have a circular form. FIG. 7 shows a division, in principle, of the leaves in case of a square table.

In FIGS. 4-6 is shown, in a table with frame 40 and list-

cross

41, 44, how uppennost placed sliding bars 101 can be pulled out and pushed in, sliding on supporting

lists

42 and 43 of which the underside of the supporting list 42 has a more elevated position than the underside of the supporting list 43, and how other sliding bars 102 may be pulled out and pushed in, being supported by the underside of supporting lists 41 which have a lower-positioned underside than the

lists

42 and 43. By this construction collision of the sliding bars is avoided.

As shown in FIGS. 4 to 6, in order to dispose the leaves l2, l3 peripherally about the smooth table top 11, the leaves are first pulled from within the table frame. Next the

bars

101 and 102 are pulled from within the interior of the table outwardly. As the respective bars move outwardly they are guided by the inclined edges as shown so as to raise up to present surfaces for supporting the respective leaves l2, 13 as extensions of the main table top 11. After the

bars

101, 102 have been fully extended, the

leaves

12, 13 are disposed over the surfaces of such and arrayed about the table top 11. In order to reduce the overall size of the table, the leaves l2, 13 are removed and the

respective bars

101, 102 are pushed back into the table frame. In moving back into the frame, these respective bars drop into their respective planes below the table top ll while providing a suitable vertical space for the fold over leaves I2, 13 to he slid into the table frame.

The table top is adapted for rotation about a center pin.

Iclaim:

l. A table comprising a frame;

an undivided table top mounted over said frame;

a list cross secured to said frame under said table top and including first supporting lists;

a pair of second supporting lists secured between said table top and said list cross;

a third supporting list secured interrnediately of and parallel to said pair of second supporting lists, said second supporting lists each having an underside of a more elevated position than the underside of said third supporting list and said first supporting lists each having an underside of a less elevated position than said underside of said third supporting list;

first sliding bars slidably mounted on said frame under said table top, said bars each slidably engaging said undersides of said third supporting list and at least one of said second supporting lists; and

second sliding bars slidably mounted on said frame under said table top, each said second bar slidably engaging said underside of at least one of said first supporting lists;

Whereby said first and said second sliding bars are slidable outwardly of said frame to support leaf extensions thereon in coplanar relation to said table top and slidable inwardly of said frame without colliding with each other.

2. A table as set forth in claim 1 wherein said table top is of circular shape.

3. A table as set forth in claim 1 wherein said table top is square.
