Application December 7, 1'942,,SerialNor 168,086 4 Claims 10145 5137) This invention relates to sets \ofnested leg sup- {ports for raising a selecteddistance theheight or articles of furniture, foreexampleldesks, chairs or tables. I

As is well known the height of conventional" pieces of furniture is fixedat the time of their manufacture and thereafter cannot be ordinarily changed except by reconstructing the lees or other parts thereof." i i My invention therefore contemplates the 1 proyision of asup'port whichis'arrangedto receive ,and thereby,.in efiect, increase the length of aleg of thepi'ece of\furniturewhoselheightlitiis desired to raise. i i

My invention still provision of a plurality of such supports, which @may be nested togetherinsets, one stacked upon the other, :a set for each leg of the article of furniture; to selectively raise the height of the piece of furniture to-which they are applied.

My invention still further contemplates the provision of, such atset of nested supports, in

which the units thereof otherthan the base constituting member oi a set are interchangeable.

My inventionstill further contemplates the provisional? suchzsuppori's which are substantial .inconstruction, constructed and arranged $05566.-

ceive furnitureflegs of a variety of sizes and shapes, neat in appearancesc, that they :blend withthe appearance ofthe piece of furniture to which they are applied and therefore do not mar it and which are relatively inexpensive to manufacture. i l

Other and further objects and advantages of the present invention will become apparent from the following description and the drawing in connection therewith, in which Fig. 1 is a vertical sectional view of the base member of a set of supports, according to my invention and showing in dotted lines the leg of an article of furniture arranged therein.

Fig. 2 is a plan view thereof.

Fig. 3 is a vertical sectional view of a set of nested supports, according to my invention, and showing in dotted lines the leg of an articl of furniture arrangedin the top unit of th set.

Fig. 4 is a plan view of an interchangeable extension unit of a set of supports, according to my invention.

Fig. 5 is a perspective view of an article of furniture, such as a table, the legs of which are arranged in the base member of a set of supports to raise the height of the table. I

Referring now to the drawing, each set of supports comprises a base member ID and one or any further contemplates the greater number ofuinterchangeable uppergor extension units: l2, which may be nested in each other and in a base member i=0.

To :give greater stability to the ,SupDQrt and the articleof furniture. the height from the :floor of which is to be raised, and (to enhance thel 'ai pearance of the supports, I prefer to arrange on the base member I0. a collar-like fiange l4 toiorm the cup or socket 1,6, in each of: which sockets a :turniture leg i 8 is received. integral with and extending up, from the platform 20, the areaof *whichis ofdesired magnitude larger than. area of the preferably cylindrical leg receiving cup orv socket forming housing or flang M. It will ,be

understood that the platform 20 may bedispensed ,wvith. the base member being cylindrical throughwout'orof any "otherselected shape and size, consonant with the desired stability of support,

In order toprovide a cup cr-socket I6, which will accommodate furniture legs of divers sizes and shapesbIform the cupeor socket so that ithas a ,relativelylarge diameter at the entrance thereto, which decreases progressively and uniformly downward to theufloor 2210f Lthecup or socket.

I prefer to make smooth and unimpeded the inisidesurface 2d of the socket which is preferably inthe shape of an inverted truncated cone, al-

though anyothe-r shape may be used.

Because of the decreasing inner socket diameter, legs ofdiiierent sizes maybe used with the supports, the smaller the size or width of the leg,

which is received in the cup or housing, the closer to the floor 22 will it be positioned and the larger the size or width of the leg the closer will it be positioned to the upper edge 26 of thecollar l4.

Because of the uniform decrease of the inside diameter, particularly becaus of the unobst'ructed inside, surface 24 of the socket, a furniture leg arranged therein will be wedged in the socket by the weight of the article of furniture.

While I prefer to make my furniture supports from wood because of the easeand relatively inexpensive wood turning operations used, and the comparative softcharacteristic of such material, it will be understood that these supports can be made "from any other material, for example plastic or metal.

Referring now to Fig. 5 wherein I illustrate an example of the use of my invention, should I it bedesired toraise the height of the top sur- 1 face 28 of the desk or table 30, the legs l8 thereof are each arranged in the socket or housing of the base member I 0 of a set of my supports,

in effect to thereby increase the length of the sion units I2, which are interchangeable with each other and which may be nested together and in the base member ID, as illustrated in Fig. 3 to increase, as desired, depending on the number of upper units used, the effective height of the support.

The outside surface 34 of each interchangeable extension unit I2 is formed of shape, corresponding in size and configuration to the shape of the cup or socket I6, of a base member so that it can be seated, nested therein (in the illustration that of an inverted truncated cone).

Similarly each extension unit is provided with a socket 36 having a relatively large diameter at the upper edge 38 thereof, or entrance thereto, which decreases progressively and uniformlydownward to the floor 40 of the socket 36.

The sockets 36 of each upper or extension unit is the same in size and shape as that of any other upper or extension unit and of the base member socket l6 so that furniture legs of divers shapes and sizes will be accommodated in any one of them and so that the extension units may be interchangeably nestedin the base member 7 to adjust the height of the support to any selected magnitude.

While I have illustrated in Fig. 3 my supports as comprising a set consisting of a base member and two extension units, it will be understood that any greater number of upper or extension units may be included in each set of supports.

While I have described an embodiment of my invention, I do not intend to be limited to the specific details thereof but intend that my invention be limited only by the scope of the appended claims and the state of the prior art.

I claim:

1. An extensible'device in the form'of a set of nested supports for adjusting the height of an article of furniture, comprising a base member having a platform rectangular in form and a collar having a diameter less than the base and extending up from the platform, the interior of said collar forming a socket to receive and house therein a leg of an article of furniture the height of which is to be raised, the interior of said collar constituting acup in the shape of an inverted truncated cone and an extension unit, the exterior of which corresponds in size and shape to the said cup for nesting the extension unit in the base member, the interior of said extension unit corresponding in size and shape to the cup.

2. An extensible device for adjusting the height of an article of furniture, in the form of a set of nested supports comprising a base member and an extension unit nested therein, said base member having a cup-like interior for receiving therein a leg of the article of furniture the height of which is to be adjusted, said cuplike interior decreasing in ection uniformly progressively from the top edge of the member to the floor thereof, the exterior of the extension unit coresponding in size and shape to the cup-like interior of the base member for nesting the extension unit therein and said extension unit having a cup-like interior decreasing in section uniformly progressively from the top edge of the extension unit to the floor thereof.

3. An extensible device for adjusting the height of an article of furniture, in the form of a set of nested supports comprising a base memthereof.

,4. An extensible device for adjusting the height of an article offurniture, in the form of a set of nested supports for each leg of the article of furniture, each set comprising a base member and an extension unit removably nested therein, the interiors of both the base member and the extension unit decreasing in section from the edge to the floor thereof.
