Abstract
Abstract The device is of the clip-frame type designed to display a document in the form of a text or picture. It comprises spring clips designed to hold the edge of the document against a rigid plane support by means of claws. Each clip is rivetted to the support and the claw on each clip is at the end of a curved branch incorporating a lever. The curvature and elasticity of this branch tend to hold the claw against the document or an optional piece of glass over it. When the lever is depressed the clip "opens" and the claw moves back to enable a document to be inserted or removed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
206 words
Device for mounting planar element such as a document in the form of a text, picture or the like, comprising a plane support having a front surface on which said document is to be mounted and a plurality of spring clips on a back surface of the support, each clip having at least one claw for engaging over a respective edge of the support and overlaying said front surface of the support to retain the planar element thereon, each clip having a base fixedly attached to the support and an elastic branch extending from the base and terminating in said claw, the branch being curved for applying two elastic forces to the claw, one of said forces being in a direction from the respective edge of the support towards the center of the support and the other of said forces being in a direction from said front surface of the support to said back surface of the support, each clip further including an offset lever extending outwardly from the branch towards the base and generally parallel to the support for reversing both said force simultaneously when the lever is depressed to eliminate the offset thereby dis-engaging the claw from over the respective edge of the support.

Device for mounting planar element such as a document in the form of a text, picture or the like, comprising a plane support having a front surface on which said document is to be mounted and a plurality of spring clips on a back surface of the support, each clip having at least one claw for engaging over a respective edge of the support and overlaying said front surface of the support to retain the planar element thereon, each clip having a base fixedly attached to the support and an elastic branch extending from the base and terminating in said claw, the branch being curved for applying two elastic forces to the claw, one of said forces being in a direction from the respective edge of the support towards the center of the support and the other of said forces being in a direction from said front surface of the support to said back surface of the support, each clip further including an offset lever extending outwardly from the branch towards the base and generally parallel to the support for reversing both said force simultaneously when the lever is depressed to eliminate the offset thereby dis-engaging the claw from over the respective edge of the support.
Claim 3
Dependent Claim
47 words
Device according to claim 1, wherein each clip comprises at an end opposite said elastic branch a lug bent so as to be spaced from said back surface of said support and incorporating means for fastening said clip to a hook, stand, string or like support device.
Claim 4
Dependent Claim
15 words
Device according to claim 2, wherein said end opposite said elastic branch incorporates a notch.
Claim 5
Dependent Claim

Device according to claim 2, further comprising a stand having at least one housing adapted to accommodate the lower edge of said support and said optional transparent plate and a branch with an opening in its end adapted to accommodate said lug of one of said clips.
Claim 6
Dependent Claim
44 words
Device according to claim 4, wherein said lug is formed with a hole and said opening in said branch adapted to accommodate said lug is formed with a relief member adapted to engage in said hole when said support is fitted into said stand.
