This invention relates to a, reversible, folding shelf structure, which can take up three dififerent positions, namely a position in which the shelf hangs in a vertical plane, and two positions in which the shelf is supported horizontally, with either one of its sides facing upwardly. The structure in accordance with the invention is of particular usefulness as a shampoo and utility tray for ,a beauticians chain When used in this manner, one

s de of the shelf may be used as a shampoo tray and may be provided with a hinged shield having a neck receiving bay while the other side may be used as a utility cantilever position, at either of its two horizontal positions and the specific means for holding the shelf comprises U-shaped portions which engage a flat portion therebetween. More specifically, the support is made of a U-shaped bar, which in one position engages between the legs thereof a flat portion of the shelf, and in the other reverse position is itself engaged by a U-shaped portion of the shelf itself. Hinge means are provided to hold the shelf in its vertical folded position.

An embodiment of the invention is illustrated byway of example in the accompanying drawings, in which:

Figure 1 is a general perspective view of the shelf structure attached to a beauticians chair, in the position where it is used as a shampoo tray;

Figure 2 is a perspective view with the shelf in folded position;

Figure 3 is a fragmentary, vertical section of the shelf, in the position of Figure 1;

Figure 4 is a fragmentary, vertical section of the shelf, when used as a utility table, with the side opposite the shampoo tray facing upwards; and

Figure 5 is a fragmentary, vertical section of the shelf in the folded position of Figure 2.

In the views of Figures 3, 4 and 5, certain unessential background parts have been omitted, for the sake of clarity.

Referring to Figures 1 and 2, the shelf is formed of two panels, namely a solid panel 10, which can be seen in Figure 1, and a slotted panel 11 seen in Figure 2. At one end the panels and 11 are interconnected by a continuous end portion 12 (Figures 3-5), and at the other end by open hinge portions 13. Preferably, as shown in particular in Figures 3-5, the shelf is formed of a single piece of sheet metal suitably bent to provide the end connection 12 and the hinge portions 13, said hinge portions being welded to the margin of the free end of panel 10, namely at 14, as shown in Figure 1. The resulting structure may thus be defined as two panels, held in spaced relation by end connections 12 and 13.

The support for the shelf is formed as a continuous United States PatentlOi ice flat bar, bent to provide an' upright 15, and two legs 16 and 17 of a substantially Ushaped portion. The upright 15, as shown in Figure 1, is held in position at the back of the chair by means of a bracket 18 having a set screw 19, which enables adjusting the position of the support. The upright 15, is preferably provided with a knee 20, the portion of upright 15 above the knee extending rearwardly.

As shown in Figures 3-5, the upper leg 17 of the U- shaped portion of the support comprises at the end thereof a transverse rod 21 which is adapted to engage the hinge portions 13, as in Figures 2 and 5, and thus to hold the shelf in its folded vertical position.

The panel 11 of the shelf, as shown in Figure 2, comprises a slot 22, of -width slightly larger than the width of the bar out of which the support is made. The slot 22 is continued in the end connection defined byhinge portions 13, between said hinge portions, and the opposite end thereof is slightly spaced from the other end of panel 11, such spacing being of approximately the same size, as the length of the U-shaped portion defined by legs 16 and 17.

The various positions of the shelf are clearly shown in Figures'3-5. Starting from the folded position of Figure 5, the shelf is revolved about the rod 21 through an angle of about and is then pushed towards the right of the drawing, until it reaches the position shown 1 in Figure 4. a In this position the marginal portion of panel 10 is held between the legs 16 and 17 of the support. To enable'the shelf to be held securely inthis position, wherein the shelf is used as a utility table, and may therefore have bottles and other objects placed thereon, a ratchet-tooth locking arrangement is provided. One tooth 23 is located on the inner face of the leg 16 of the support, while the other tooth 24 is located at a suitable position on the outer face of the panel 10. The tooth 24 is visible also in Figure 1. Teeth 23 and 24 engage each other when the shelf has reached the position of Figure 4, and may be disengaged by forcing upwardly on the shelf, so as to slightly spread apart the legs 16 and 17 of the support.

To place the shelf in its shampoo tray position, starting from the folded position of Figure 5, the shelf is revolved about rod 21 through approximately 270, and is then pulled towards the left of the figure until the U- shaped support portion defined by legs 16 and 17 finds itself in the U-shaped portion defined by panel 10, end connection 12 and the solid portion of panel 11, this end position being shown in Fig. 3. It will be seen that, in reaching this position, the support has travelled through the whole length of the slot 22.

As shown particularly in Figure l, the panel 10 has upstanding side walls 27, to channel the water into a sink, when the shelf is used as a shampoo tray. At the end of panel 10, adjacent the end connection 12 is hinged a shield 25 having a neck-fitting bay 26. The shield 25 is freely pivotable so as to be adjustable to various positions, said shield being held in these positions by contact with the neck of the person who is using the chair.

It will be seen that in the position of Figures 1 and 3, any rearward pressure on the shelf, such as may be exerted through the shield 25, will only tend to push the shelf backwards into even more firmly engaged position. To keep the shelf longitudinally aligned, ribs 28 are preferably provided in the U-shaped portion of the shelf, between panel 10 and the unslotted portion of panel 11, these ribs, as can be seen in Figure 2, being substantially in line with the edges of slots 2-2, so as to engage longitudinally the edges of legs :16 and 17 of the support.

The free edges of shield 25 and of walls 27 are preferably provided with protective resilient rims 29.
