Description: The innovation relates to a pivot spring

in other words, Bi iaerrarimeri.

It is known that picture frames with a circumferential inner groove for holding the picture can be secured with pins or metal triangles that are driven in from the side. In addition, it is possible to attach pivoting springs to the rear wall of the frame to make it easier to change pictures. This includes a spring finger that can be pivoted into the circumferential inner groove of the frame*

The innovation relates to a pivot spring that is particularly easy to design and manufacture for these purposes.

The novel pivot spring, in particular for picture frames according to the preamble of claim 1, is now characterized in that the spring finger is pivotably attached to brought base part is bent and slightly bent up at the free end to the springy rear grip of the groove, whereby 6 spring fingers have a punched out so that it has a frame-shaped design and the punched out beginning at the crank also has a support rag on the base part.

In detail, the frame-shaped spring finger has one or more bent side tabs on both sides, which are particularly recessed relative to the

Outer edge is stamped and rolled. The side flaps are preferably bent into a quarter round.

A preferred embodiment is shown for example in dsT drawing dsrgsstsllt uv.d ?

Figure 1 shows the top view of a new type of pivot spring,

Figure Q. the side view of this pivot spring in operation,

Figure 3 shows the section along line A-A of Figure 1 and Figure 4 shows the front view of the pivot spring.

As can be seen from the drawing, the new type of swivel spring has a base part 1, which is pivotably attached to the backboard 3 for the picture frame 4 by means of a rivet 2. The base part 1, together with the spring finger 6 bent at 5, serves to springily grip the inner groove 7 of the picture frame 4 when swiveled in, and thus to replace the inserted picture 8.

The spring finger 5 is slightly curved at the free end 9 for spring engagement with the groove 7 at 10 and has a punched-out section 1t so that it has a frame-shaped design, whereby the punched-out section 11 beginning at the offset still leaves a supporting tab 1; base part 1.

The frame-shaped spring finger 6 has one or more, here two, bent side tabs 13 on both sides, which (13) are designed as a quarter foundation and serve to facilitate the pivoting for locking and unlocking the spring finger 6 with the pivotable base part 1. These side tabs 13 are punched in a recess relative to the outer edges 15.

This results in a simple swivel spring/safe, replaceable holder for pictures with frames and cardboard backing, which can be formed from a springy metal strip by punching and embossing.
