1 My present invention relates to the general. art of shelf construction and, more particularly, to a demountable corner shelf.

. Popular trends in interior decorating call, more and more, for the of objects of art of the types made of glass, eeramicsor metal, to supplement the older forms 'of wall decoration, which were largely through the use of pictures of one sort or another.-` Further, in order to sustain interest and give the housewife an opportunity to change her decorative scheme at intervals, there has been an increasing demand for 'demodntable shelving that 'can be put into use 'as occasion warrants, and then be taken down when not needed. Undersuch conditions, it is very desirable that the unit be easily demount'ed for storage. It to snppfhr thisdemand that I have created-my demountable corner shelf'.

vThe .principal object of my present invention, therefore, is to provide a corner shelf that be easily Ya-sse'rnblecl and put into the position 'of use or disassembled for rconvenient storage.

afurther object 'of Amy invention is to provide a derhountable shelf which is so interlocking that the whole unit is a rigid, lixed shelf assembly that will not become loosenedor dislodged so that valuable objects, or works of artI and the like, will not be placed in jeopardy or bejdamaged.

A further object of my present invention is to provide a demountable sheli for 'use in the corner or a: room, and which lends itself to easy,

manufacture withthe various types of sheet material now available.

-rther objects, advantages `and capabilities will 'be apparent 4from the description anddisclosure inthe drawings or may be comprehended or are inherent in the device.

In the drawings:

Fig. 1 is a perspective View showing one form of my shelf in its assembled form.

Figs. 2, 3, and 4, show progressive steps in ther assembly of my demountable shelf with certain parts shown in section to better illustrate their construction, ltaken substantially along the line 3-3 of Fig. 1.

Fig. 5 is a fragmentary cross-sectional view taken along the broken lines 5-5 of Fig. 1.

Referringl more particularly to the disclosure in the drawings, the numerals Hl and l2 designate, respectively, the two side members of demountable shelf. In outward appearance, these two shelf-supporting members are identical in outline, excepting that supporting member I0 must have additional material on the inner side so as to form the final corner securing means, as is illustrated in Fig. 5, wherein itwillbeapparent that member it! must be of suiiicient .increased size over member le so that inw-ill Yoverlap the same -and provide for the line-l securing 'screws I4..

Inmy illustrationst have shown, for use -with the 'sheif supporting members it and 12, twov shelves-as 'i6 and I8. It will be apparent, 'it' is believed, that 'any reasonable number of' shelves might be used. The various shelves need not all be the same size 'or have the saine outward contour, but the securing meanswhich interlocls .with the supporting members Ell and ft2 must be of the .same design and size, in order vthat assembly and disassembly lcan be achieved.

Each of the shelf members is. provided with two bearing edges as 2t and 2 I. These two edges meeta't 22.110 complete the shelf` proper and the included angle must correspond to the .angleA at. which the ltwo shelf :supporting members It and li2 are disposed. This normally is a right angle but it lwill be apparent from the structure that this need not necessarily be true, as the construction can be made to conform to any angle ,less than a straight angle.

. @nfea'ch of the two edges 2u and .2i I provide an engagement 'member lor tongue,as 23 and *24. These tongue members are undercut 'as at 28,1an'd are beveled oil :at 28,-50 .that they .may be Vsecurely "5 engagedwithin slots .3B 4and 32, out respectively in 'theshelf supporting members til and i2, and as will best be observed in Figs. 1, 3 and l, each oftheslotsare beveled at their ends; the vbevel l at 34- being so angled as to Vform a rez-entrant angle and provide .a firm engagement with the undercut portion 26 of the tongue members.

Similarly, the opposite end 35 is .beveled so as to accept, in snug engagement, the bevel 28 ofthe shelf member. It follows that the bevels and the spacing of the beveled surfaces must conform to the proportions of the

tongue members

23 and 24, so that when fully engaged there will be in-` timate contact throughout the length and breadth of the tongue into

slits

30 and 32 in the shelf supporting members.

In assembling my shelf structure, the shelves are positioned normally'on edge, after the showing of Fig. 2. Then the two shelf-supporting members l0 and I2 are brought into position, so that beveled surfaces 34 may be engaged under their respective overhanging portions 26 of the tongue members. Then by an upward movement and by pressing inthe top of the shelves, as indicatedby arrows 36 and 3l in Fig.`3,

tongues

23 and 24 are fully entered into their corresponding slots 3B and 32 in the shelf-supporting members and the surfaces or edges 2D and 2l are in firm engagement with the shelf members, as is probably best illustrated in Figs. 1 and 4.

In this assembled position, if the shelf unit were to be placed immediately into the corner of the room and secured there, the entire device would be locked so that its various members could not loosen or separate. However, it has been found most convenient to provide that the shelf be a rigid unit even before being placed in a corner, and to achieve this, I have provided a plurality of securing screws i4, which are passed through the overlapping shelf-supporting member l and threaded into the companion support member I2 that is probably best illustrated in Fig, 5. When so arranged, the unit is so locked in that any handling, such as might occur in the nal placement of the device, will not loosen any of the parts. For convenient hanging of the shelf, I provide a plurality of screw holes as 39.

It is believed that it will be apparent from the above description and the disclosure in the drawings that the invention eomprehends a novel construction of a demountable corner shelf.

Having thus described my invention, I claim:

1. A demountable corner shelf, consisting of: two shelf supporting members adapted to form an angle by abutting along a common line; means for securing said members in their abutting relationship; said shelf supporting members adapted to lie in intimate Contact with the walls forming the corner in which the shelf is to be used; a plurality of shelf members having an interior angle formed by the sides adapted to engage said shelf supporting members; said shelf supporting members having co-acting slits, one in each member, disposed in the same horizontal plane; said slits having their ends beveled so they are directed toward the line of abutment of said shelf supporting members; said shelf members having tongues extending outwardly from their sides forming the interior angle and of a length substantially equal to and adapted to co-act with the slits in said shelf supporting members; said tongues having their inner ends beveled at an obtuse angle to coact withthe inner end bevels of said slits and having the outer ends cut with a re-entrant angle to co-act with theouter end of the said slits to form an interlocking securing means for said shelf members when the shelf unit is assembled as a whole. l

2. A demountable corner shelf, consisting of: two shelf supporting members adapted to form an angle by abutting along a common line; screw means, spanning the common line, for securing said members in their abutting relationship; said shelf supporting members adapted to lie in intimate contact with the walls forming the corner in which the shelf is to be used; a plurality of shelf members having an interior angle formed by the sides adapted to engage said shelf supporting members; said shelf supporting members having co-acting slits, one in each memberdisposed in the same horizontal planefsaid slits having their outer ends beveled so they'are directed toward the line of abutment of said shelf supporting members; said shelf members having tongues exf act withV the outer end of the said slits to form an interlocking securing means for said shelf members when the shelf unit is assembled as a whole.

3. A demountable corner shelf, consisting of: two shelf supporting members adaptedto form an angle by abutting along a common line; said shelf supporting members adapted to lie in intimate contact with the walls forming the corner in which the shelf is to be used;` a plurality of shelf members having an interior angle formed by the sides adapted to engage said shelf supporting members; said shelf supporting members having co-acting slits, one in each member disposed in the same horizontal plane; said slits having their outer `ends beveled so. they are directed toward the line of abutment of said shelf supporting members; said shelf members having tongues extending outwardly from their sides forming the interior angle and of a length substantially equal to and adapted to co-act'with the slits in said shelf supporting membersysaid tongues having their outer ends cut with a re-entrantangle to coact with the outer end of the said slits to form an interlocking securing means for said shelf members when the shelf unit isassembled as a whole.
