1 Claim. l

This invention relates to a supporting structure such for instance as a shelf which may be positioned in a cupboard for supporting groceries, condiments, and the like in a stored relation.

Usually a closet is so arranged that a person cannot readily reach all the articles, some of which may be positioned at the back of the closet and thus the entire volume of the closet is not utilized to best advantage.

One of the objects of this invention is to provide a shelf which may be moved so as to cause its contents to be readily available at all positions and thus one which when located in the closet will cause the entire contents of the closet to be readily accessible.

More specifically this invention relates to a supporting shelf which may be rotated to present the contents of the shelf at an accessible point for removing the same from the shelf- With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings:

Fig. 1 is a perspective view of the supporting structure;

Fig. 2 is a central sectional view showing the shelves differently arranged.

In proceeding with this invention, I have provided a base upon which there is mounted a plurality of shelves, each rotatable about a spindle extending upwardly from the base. 'Ihe shelves may be spaced different distances apart by reason of sleeves which are located on the spindle and provide an adjustable spacing for the shelves.

With reference to the drawings, I designates a base upon which the supporting structure rests. This base is curved at its peripheral marginal edge as at Il so as to space the bottom thereof above the support on which it rests. A spindle I2 extends upwardly from the base and is secured thereto by means of threads I3 and nuts I4 and I5 on either side of the bottom wall I0 of the base.

A shelf I6 has a collar l1 which is xed thereto by means of washers threadedly received on one end of the collar and with the washers positioned one on each side of the shelf so as to bind the shelf and collar to each other. along bearing for the shelf to rotatably mount it on the spindle I2. The collar rests upon the nut I4 as shown in Fig. 2 to position it on the The collar forms spindle. A sleeve I8 is positioned upon the collar I'I and a second shelf I9 having a collar 20 fixed thereto as before described is rotatably mounted on the spindle l2 with the lower edge of this collar 20 engaging the sleeve I8 to support it in position. Further sleeves 2| and 22 are positioned above the shelf I9 and a nut 23 is positioned on the threaded end 24 of the shaft I2 to hold the parts assembled.

In some cases, it is desirable to vary the spacing of the shelves from that shown in Fig. 2 and I have shown in Fig. 1 the sleeves 2| and 22 positioned beneath the shelf I9 so as to provide a different arrangement and greater spacing of the shelves. Inasmuch as the sleeve 22 is of about half the axialextent of the sleeves 2| and I8, a variety of spacings may be had by variously positioning the sleeve on the spindle I2, either above or below either one of the shelves which are there provided. Various articles may be positioned on either of these shelves which are retained therein by upturned rims 25 and the shelves may be rotated so as to bring the article carried thereby into accessible position for one using the device.

I claim:

A supporting structure comprising a base, a spindle extending upwardly from said base, a plurality of sleeves of different axial extent removably and rotatably mounted on said spindle one upon the other upwardly from the base, at least one of said sleeves serving as a hub for a shelf carried thereby and extending therethrough and collars on both sides of the shelf threadedly secured to the hub, said hub providing a bearing for rotatable mounting on a spindle whereby the shelf may be adjustably positioned for rotation about the spindle with reference to the base by selecting the order of arrangement of the sleeves with reference to the base.
