' 3Claims. (01.211-114) I This invention relates to new and useful improvements in a collapsible shelf and bookcase.

The invention has for an objectthe construction of a device as mentioned which is charac- -terized by a plurality of superimposed shelves,

an-dropes associated with the shelves in a particular manner for holdingthem in relatively fixed postions.

More specifically, the invention contemplates passing theropes through openings in the shelves and providing. a means for fixedly connecting the ropes with the shelves.

Still further, in one form of the invention, it is proposed to windthe ropes around portions of the shelves in a specific manner, and it is proposed to mount clips on the shelves engaging over portions of the ropes to secure these parts fixedly together.

In another form of the invention it is pro posed that the ropes be passed through tubes Q mounted on the shelves, and to provide projecting portions from the tubes to clip and hold I the ropes.

For further comprehension of the invention. and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a Ina- I terial part of this disclosure;

Fig. l is a perspective view of a collapsible shelf and bookcase constructed according to this invention.

Fig. 2 is a fragmentary enlarged plan view of Fig. 1.

Fig, 3 is a front elevational view of Fig. 2. Fig 4 is a fragmentary enlarged vertical sec-- tional view taken on the line 44 of Fig. 1. I

I on the line s-a of Fig. 7.

Fig. 9 is a perspective View of the rope holding tubes illustrated in Fig. '7.

Fig. 10 is a horizontal sectional view, taken on I the line Ill-40 of Fig. 9.

The collapsible shelf and bookcase, according to this invention, includes a plurality of superimof the top shelf, up through the center notch I9,

posed shelves 10, II and I2. Ropes I3 and I4 pass through openings in these shelves and are associated with holding means for fixedly connectingthe ropesto the shelves. The upperends ofthe ropes I3 and Mare connected with rings I5 provided with hooks I6 by which the bookcase may be supported on an overhead bar or othor support,

Each of the shelves is formed with notches I8 at one side of the front and rear edge thereof, and a central notch 20 at the center of the side edge. Each of these shelves is formed with additional notches 20 at the front and rear edges near the other side thereof, and a central notch 2| at the center of the side edgebetween the notches 20. I. The rope I3 is Wound around portions of the shelves between the notches I8, while the rope I4 is wound around portions of the shelves between the notches 2D. The winding is identical for each of the ropes. This winding maybe understood by examining Fig. 6.

Starting at one end of the rope I3 adjacent the hook I6 the rope extends down to the notch l8 in the. top shelf I0, then around the bottom face across the top face and down through the notch I8, and further down to the next shelf II. At this next shelf the rope continues through one of the notches I8 around the bottom of the shelf, up through the central notch I9, across the top of the shelf and down through the same notch I8. I

The rope then continues downwards to the third shelf I2, and here it extends down through the notch I8, around to the center notch I9, up across the top face of the shelf, down through the same notch I8 across the entire depth ofthe bottom shelf I2 along the bottom thereof and up through the notch I8 at the rear side of the shelf I2. The ropethen continues around and around I opening 26 for a bolt. The clips 25 are used in pairs (see Fig. 4) one upon the top face of the shelf and the other upon the bottom face. A bolt 2'! is engaged through the openings 26. The clips are arranged to extend over the central notches I 9. The ends of the clips engage over portions of the rope immediately adjacent the notches I9. When the bolts 21 are drawn tight the slips will securely hold portions of the rope.

In Figs. 7 and 8 a modified form of'the invention has been disclosed which distinguished from the prior form in the mounting and arrangement of the ropes. According to this form there is a plurality of superimposed shelves, 28, 29 and 30. Tubes 3| are mounted through the corners of these shelves from the top to the bottom. These tubes 3| are formed with projecting flange portions 3W belowthe shelves for fixedly mounting the tubes thereon. Ropes33 pass through the tubes 3!. tubes 3| and engage and hold the ropes 33. The upper ends of the ropes 33 are connected with hooks 34 which may be used to suspend the article.

While I have illustrated and described the pre-' ferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined inthe appended claims.

Portions 3| are crimped in the Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. A collapsible bookrack or the like comprising a plurality of super-imposed shelves adapted to be supported in spaced relation to each other, the sides of each of said shelves being divided into front and rear portions by a notch extending inwardly from each side edge thereof, .a supporting rope at each end of said rack, said ropes being wound, successively, around said front portions and, successively, around said rear portions, and clamping means at each of said notches for holding said ropes in non-slip relationship withsaid shelves.

2. A collapsible bookrack or the like as claimed in claim 1, each of said clamping means includi-ng an elementengaging the shelf adjacent said I notch, and the portion of the rope wound around the front and rear portions of the shelf.

3. A collapsible bookrack or the like as claimed in claim 1, each of said clamping means including upper and lower jaws, and a threaded bolt engaged through said jaws and disposed in said notch. I
