United States Patent 3,009,275 ADJUSTABLE FRAMES Herbert Olof Rosenberg, Vikstensvagen 41, Johanneshov, Stockholm, Sweden Filed June 27, 1960, Ser. No. 38,782 4 Claims. (Cl. 40-1521) This invention relates to adjustable frames or supports for pictures, placards, mirrors and the like, and has for its object the provision of a device of the character described which is simple in construction and which is readily adjustable to accommodate pictures, and so forth of varying size and conformations.
In the preferred form of invention, the frame is so constituted and constructed that the same may be rolled or nested into relatively small compass.
Preferably, a frame of the invention comprises two strings or tapes of iron which may be cut in desired lengths and which are fastened at the corner of the pictures by means of hook-like members.
In the drawing:
FIG. 1 shows the rear side of a picture or placard provided with the frame according to the invention.
FIG. 2 shows a hook-like corner member composing one of the elements of the frame.
FIG. 3 is a side view of FIG. 2.
FIG. 4 shows a corner member fastened to a tape ele ment.
FIG. 5 shows a ring shaped member clamped on the tape member.
FIG. 6 is \a side view of FIG. 5.
FIG. 7 shows a modified corner member.
FIG. 8 is an end view of the modified corner member.
FIG. 9 is a sectional view on line 9-9 of FIG. 8.
FIG. 10 shows a metal plate to be folded in the form of a corner member according to FIGS. 8 and 9.
Referring now to the drawing it will be seen that the invention contemplates a frame structure in which four corner plates 1 are coupled together pairwise by means of two-tape like flexible members 2. A wire 3 is fastened to the tapes '2 in such a manner that the picture can be hung on the wall. The corner plates engages the corner parts of a picture or placard 4 and the like by means of U-profiled flanges 5 and 6 arranged in right angles to each other. The flanges 5 and 6 form the end portions of a back plate 7 engaging the rear side of the picture with its mat, glass and backing whereat the flanges are arranged to engage, receive, or accommodate an edge of the picture. An arcuate bow member 8 concentric with the corner of the picture is produced by a stamping and pressing process so that the bow is spaced from the back plate 7 and forms a slit shaped opening 9 as shown in FIG. 3. The tape 2 is with its end portion introduced into said slit shaped opening and is bent in such a manner that the free end portion of the tape can be locked together with the tape by means of a sleeve v10.
The only measure for the adjustment of the frame after the size of the picture consists in cutting the two tapes 2 in suitable lengths.
The arcuate bow 8 concentric with the corner edge of the picture permits different directions of the tape 2 in dependence of the format of the picture.
Each end of the wire 3 is fastened to a ring 111 consisting of two turns 12 and 1 3 of a helical spring. The tape 2 is introduced between these two turns of the ring 1 1 from above so that the ring serves as a hook carrying the picture. Due to the tension of the spring the ring 11 is maintained in position by the aid of the force of friction.
In FIGURES 7 to 10 a modified structure of the corner plate is shown. The corner plate is designated by 14 and differs from the plate 1 in that the back plate 15 is double and consists of two layers 16 and 17 and that the flanges 18 and 19 are connected to each other forming a real corner 20. The arcuate bow 21 is also doubled and produced in the same manner as the arcuate bow 8. The double layers 16, v17 of the back plate impart to the con-truction increased tenacity and said layers are fastened together by means of the bow 21. The corner plates are produced of sheet material preferably of aluminium. The corner plate 14 consists in developed form of two diametrically opposed sectors connected to each other by means of the flanges 18 and 19 as shown in FIG. 10.
The sectors form the two layers 16 and 17 of the back plate. After folding the stamped piece of sheet metal along lines 22 and 23 to form the corner plate the arcuate bow 21 is formed by simultaneously pressing the two layers '16 and 17. Thus, these layers will be locked together.
What I claim is:
1. An adjustable frame for a rectangular object comprising a pair of tape-like members including hook-like end portions, two pairs of corner plates adapted to be fitted onto the corners of said rectangular object, each corner plate including an arcuate bow member arranged in a plane parallel with the object and concentric with the corner of the object, the hook-like end portions of the tape-like members engaging the arcuate bow members associated with a pair of diagonally situated corner plates.
2. An adjustable frame according to claim 1 in which each arcuate bow member defines a slot shaped opening with the associated corner plate.
3. An adjustable trame according to claim 1 wherein each corner plate comprises a back including two layers connected with the associated arcuate bow member.
4. An adjustable frame according to claim 1 in which the corner plate is of sheet material substantially in the form of two diametrically opposed sectors connected with each other.
