SUMMARY or THE INV NTION i A frame means which is constructed for fixed attachment to a plane surface, such as a wall, by a plurality of screws or projection, which defies removal without destruction. A'backing plate associated with the frame means has a plurality ofespecially formed openings or slots to complementally engage complementary projections or heads of screws, so upon movement of the frame means, which may carry amirror, picture or the like, with respect to the projecting screwheads, the frame is locked into place against retrogression or removal.

A framemeans surrounds and overhangs theedges of a mirror or picture means and is secured against removal, once it is within'the frame, and is locked in place bytoothed means, against separation or retrogression.

The backing plate is of a material of such resiliency, that, when the heads of the screws or projections are moved into the respective openings or slots past the resilient tongues, the tongues move behind the screw or projection to prevent retrogression of the backing plate which is fitted within the frame means.

A theftproof frame means for mirror, pictures or the like comprises a channellike frame surrounding themirror or picture, and overlapping the mirror or picture, which frame is held together by toothed members which may be forced into biting engagement within the channellike frameand whenthe toothed members are forced into openings,the teeth will bite into theframe to maintain the frame against retrogression'and FIG. 1 is a perspective view-ofthe mirror or picttire accord ing. to the present invention, with parts broken away and shown in section to bring outthe details of construction;

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings wherein like reference characters designate like parts in the several views thereof, and as seen most clearly in FIGS. 1, 2, 7 and 8, the mirror or picture frame means is designated generally by the reference numeral I0, and includes substantially

elongated frame portions

12 and 14 forming the sides and ends respectively of the frame means I0.

The

elongated frame portions

12 and 14 are preferably formed of modified channels, each having a longitudinal opening 16 formed therein with inturned ribs 18 and with laterally extending flanges 20. Each longitudinal opening 16 is of a character to receive one end of toothed wedge member designated generally at 22, which member 22 is preferably made of hard metal. Each wedge member 22 has toothless portions, as indicated at 24, and toothed portions, as indicated at 26, thereon. This enables the toothless portions 24, of each wedge member 22, to be inserted into the respective openings 16 of the elongated frame portions'12 and 14, the ends of which have been angulated, as indicated at 28.

The wedge member 22 is of such thickness and shape that the side of the wedge member opposite teeth 26 will force the teeth into biting engagement with

elongated frame portions

12 and 14 within the elongated openings 16 therein, and, when each of the elongated frame portions 12 and I4 is forced thereonto, as shown in FIG. 6, the teeth 26 will engage in the metal of the respective elongated frame portions in the elongated opening 16 therein to such extent as to prevent retrogression of the toothed wedge members 22 with respect to the respective

elongated frame portions

12 and 14. The

elongated frame portion

12 and 14 may be pressed onto the respective toothed wedge members at each corner by any conventional-type press, however, once these are pressed into position, as indicated in FIGS. I, 2, and 6, they become inseparable, unless damaged or destroyed.

When a mirror or pictureof the proper size, as indicated at 30, is positioned within the frameformed by the

elongated frame portions

12 and 14, and with the proper cushioning fiberborads 32 around the edges of the mirror or picture 30, and positioned intermediate the mirror or picture and the inturned ribs 18, and with a suitable fiber-backing board 34 between the mirror or picture 30 and a-backing plate 36, such as a plate of resilient metal, which mirror or picture 30, backing board 34, and resilient metal backing plate 36 become a composite assembly within frame 10.

The backing-plate 36 has a plurality .of openings or inverted Y-shaped slots 38 formed therein at spaced intervals, as will best be seen in FIG. 2, which FIG. shows the frame with the mirror and fiber backing board removed to show the location of the openings or inverted Y-shaped slots 38, as well as the position of the screws or projections 40, both prior to and showing only the backing plate, and showing the projections or screws in dashed outline position prior to'the installation of the-mirror or picture frame on the wall or thelike, and showing screws or projections in full outline, after the heads. have been moved inward with respect to the locking tongues;

FIG. 3 is a side elevational view of the mirror or pictures frame as-shown in FIG. 1;

after the installation of the frame 10 on a vertical surface, such as a wall 42.

Preparatory to the installation of the composite framed mirror or picture, as shown in FIGS. 1 and 3, on a wall, to prevent theft or removal or the mirror or picture assembly intact, screws or projections 40 are secured to the wall 42 so that the head 44 of each screw 40 projects outwardly, when screwed into an anchor plug 46, which may be a rawhide-type plug or it may be a mechanically expansible anchor plug, fitted within each hole 48 formed in the wall 42. It is preferable to have a projection or screw 40, which has a shoulder 50 therein, so when the inner end of the shoulder is screwed in so as to be flush with the wall 42, the head 44 of each screw or projection will project outward a sufficient distance that, when the plate 36 is pressed thereonto, the head of each screw 40 rests on a resilient tongue 52, which tongue forms a'triangular side of each inverted Y-slot or opening 38, which is of sufficient length and width to permit a head 44 of a screw or projection to cause the tongue 52 to yield to permit the head to pass through the wide portion of the inverted Y-slot 38. Thus the entire frame may be depressed to cause the several tongues 52 to move into slots 38, as indicated in dashed outline in FIG. 8, which will allow the head a 44, of each screw, to pass through one of the inverted Y-slots 38 and to the upper end thereof, as indicated in FIGS. 7 and 8. In so doing, the resilient tongue 52 will spring back into place, as indicated in full outline in FIG. 8, which will prevent the heads of the screws 40 being moved downward and out through the respective inverted Y-slots 38. Once the heads 44 of the screws 40 are in the position, as indicated in FIG. 2, the frame, containing the mirror or picture cannot be removed intact, from the wall or surface on which it is installed.

While reference is made to heads 44 of screws 40, this is to be broadly interpreted as projections, whether or not the projections are connected to a wall by screws, welding or otherwise.

The arrangement as described above, provided positive pro tection of the frame against removal without destruction thereofin part, or of the whole.

ALTERNATE METHOD OF INSTALLATION OF THE FRAME AGAINST THEFT OR REMOVAL An alternate method of assembling the frame, with a mirror, picture or the like therein, comprises assembling three sides of the frame onto the toothed wedge members 22, as by pressing, as set out above. Then, with the backing plate 36 only secured in place on the wall 42, as indicated in FIG. 2, the three assembled

elongated frame portions

12 and 14, with a mirror picture or the like, and with the fiber-cushioning strips 32 in place and with the fiber-backing board 34 in place, this assembled portion of the frame is passed laterally behind the backing plate 36, which has been secured in place in the proper manner, until the laterally extending flanges 20 extend beneath the peripheral edges of the backing plate 36 on three sides. With these

elongated frame portions

12 and 14 in this position, the fourth elongated frame portion, in which toothed wedge members 22 have been placed, are moved laterally so hat each of the toothless ends 24 of the respective toothed wedge members 22 engage within the respective elongated openings 16. Pressure is then applied, as by a press, clamps or the like, to force the teeth 26 into biting relation with the metal of the respective elongated frame portions, and the flanges 20 thereof beneath a side of backing plate 36.

When all corners of the frame are forced together, as indicated at 10, FIG. 1, and with the laterally extending flange 30 forced beneath the backing plate 36, the mirror or picture frame is secured in place against theft. By assembling the elongated frame portions I2 and 14 in this manner, the openings 38 do not necessarily have to be slotted or Y-shaped however, the frame may be assembled into a theft proof mirror or picture frame assembly in either manner as set out above.

As this invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, the present embodiment is therefore illustrative and not restrictive, and since the scope of the invention is defined by the appended claims, all changes that fall within the metes and bounds of the claims or that form their functional as well as conjointly cooperative equivalents are therefore intended to be embraced by those claims.
