8 Claims.

This invention relates to picture frames, and particularly to metal frames of the portable type.

An object of the invention is to provide a frame which is of simpleconstruction and one which may be easily and quickly assembled without the use of special tools.

Another object is to provide a frame having corner brackets which, upon assembly, provide an extremely rigid and compact unit. v

A further object is to provide a frame in which the unifying means are effectively concealed from both front and back and which prevent separation.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing, Fig. 1 is a front elevational view of the improved frame;

Fig. 2 is a side view taken on line 11-11 of Fig. 1;

Fig. 3 is a detail view of a corner of the completely assembled frame showing one form of bracketin place;

Fig. 4 is a detail sectional view taken on line IVIV of Fi 3; V

Fig. 5 is a front elevational view of one form of corner bracket, as shown in Fig. 3;

Fig. 6 is a detail view of a'corner of another frame showing another form of bracket in place;

Fig. '7 is a detail sectional view taken on line VII-VII of Fig. 6; v

Fig. Bis a front elevational view of'the form of bracket shown in Fig. 6.

In the frame illustrated in Fig. 1, the top and bottom members I and the side members 2 are formed from metal, and preferably from a ductile metal such, for example, as aluminum, which has been extruded into shapes of a general character, exemplified by Fig. 2.

In the back. of the frame, there is a channel 3 coextensive with the top and two sides. This channel receives the glass, picture, filler and easel back, and is formed by the members l, 5, 6 and 1, as is clearly shown in Fig. 2. The bottom member of the frame, however, varies slightly in form from the top and sides, in that member 4 of the bottom is narrower than it is in. the top and sides, and member 5 is omitted entirely. This provides easy access for insertion of those parts commonly employed in retaining a picture in its frame.

Adjacent recess 3 and extending entirely around the frame, there is a pocket formed by the members 8 and I and the frame front 8 for the reception of four corner brackets 9. These brackets, as shown in Figs. 5 and 8, are formed by stamping, and consist of the legs i0 which are at right angles to one another. forms of bracketsv there are provided notches for reception of a small detent or tongue of member 1. Referring to Fig. 5, the notches II, which take the shape of a trapezoid, are so formed that the side I2 is inclined at an angle of about 45 to the axis of the leg. The depth of the notch is from about one-fourth to one-third the width of .the leg III. This form of corner bracket is used in narrow frames, while the bracket shown in Fig. 8 is employed in wider frames. In the bracket of the wide type there is only one notch, and this is generally of circular form, as shown by reference character I3.

To assemble the frame, one leg IU of each of the four corner brackets is inserted into the bracket-receiving grooves of the two frame sides.

In both v The other legs of the brackets are inserted into gether, forming an exceedingly rigid joint at the miter.

The assembled unit may then be given an oxide finish. The electrolyte employed finds its way into the corner joints and in its oxidizing action further serves to make a tighter joint.

I claim: g

1. In a picture frame having a plurality of extruded ductile metal sections of channel form, a righte-angled corner bracket comprising two legs, each leg having a notch therein for the reception of a portion of the wall of said sections whereby said sections are unitarily joined.

2. In a picture frame having a plurality of extruded ductile metal sections of channel form, right-angled corner brackets having notches in the'legs thereof for the reception of a portion of the wall of said sections, one side of each of said notches being inclined at an angle to the axis of the other leg of said bracket.

3. In a picture frame having a plurality of extruded ductile metal sections of channel form, a

right-angled corner bracket having notches in notches being inclined at an angle of 45 respect to the remaining sides.

4. A picture frame comprising a plurality of extruded ductile metal sections of channel form, said sections having a groove therein for receiving comer brackets, notches within said brackets into which a portion of the wall of said sections is forced whereby the forcing of said portions intosaid notches produces a force acting on said sections to unitarily join the latter.

5. In a picture frame having a plurality of ext'ruded ductile metal sections of channel form, trapezoidal notched corner brackets for the reception of detents formed from the wall of said sections.

6. In a picture frame having a plurality of extruded ductile sections of channel form, a bracket-retaining groove within said sections, corner brackets having a notch of circular form with intermediate the ends of said brackets for the reception of detents formed from the wall of said sections.

7. In a picture frame having a plurality of ductile metal sections of channel form, a rightangle corner bracket comprising two legs, each leg having a notch thereinfor the reception of a portion of the wall of said sections whereby said sections are unitarily joined.

8. A picture frame comprising a plurality of ductile metal sections of channel form, said sections having a groove therein for receiving a corner bracket, a notch within said bracket into which a portion of the wall of said sections is forced whereby the forcing of said portion into said notch produces a force acting on said sec tions to unitarily join the latter.
