Abstract

A document displayer (10) comprises an annulus (11) and a disc (12). The annulus comprises a layer of adhesive for establishing a firm retention of the annulus on a surface such as a transparent screen. A layer of the annulus comprises a flexible rubber or plastics material which contains permanently magnetised particles. The disc (12) comprises a layer of non-magnetised magnetic material so that the annulus and disc can be magnetically held together. The displayer is suitable for retaining a licence on the windscreen of a road vehicle, the disc (12) holding the licence on the surface of the windscreen. <IMAGE>

Description

SPECIFICATION Document displayer The invention relates to a device for displaying a document on a surface. In particular, the invention relates to a device which can hold a document on a surface such that the document can be repeatedly removed and replaced. In the past, holders have been provided whereby a document is removed by the disruption of an adhesive contact between the holder and the surface. It has been found that repeated removal and replacement of the holder impairs the holder's adhesion.

According to an aspect of this invention, there is provided a document displayer comprising at least two elements wherein one of the elements includes retaining means for establishing a firm retention of the one element on a surface, and wherein the elements include a holding means for holding the elements together.

The invention provides a displayer whereby a document can be held by one or more of the elements on a surface. Respective surfaces of the displayer are of a kind whereby repeated disengagement of the surfaces may be carried out to remove and replace documents without impairment of the holding means.

An example of an embodiment in accordance with the invention will now be described, with reference to the accompanying drawings wherein: FIGURE 1 shows a front elevation of a displayer; and FIGURE 2 shows a side view of the displayer with adjacent layers separated from each other for clarity of illustration.

Figure 1 shows a document displayer 10 comprising a first element which is an annulus 11 and a second element which is a disc 12 The annulus of the displayer defines an opening for receiving a document. When in use, the displayer is mounted on a transparent screen and a document is held on the screen by the disc so as to be visible through the screen. A document is not shown in the drawing.

Figure 2 shows a cross-section of the displayer wherein different layers cpmprised by the displayer can be seen. The annulus 11 comprises layers 1, 2 and 3 and the disc 12 comprises layers 4, 5, 6 and 7. Layer 1 is a protective paper liner which can be peeled off the annulusto reveal an adhesive layer 2. Layer 2 enables the annulus to be firmly retained on a variety of different compositions of surface. Layer 3 of the annulus comprises a flexible rubber or plastics material which contains permanently magnetised particles.

The disc 12 comprises a layer of paper 4 which is laminated to a layer 5 containing a nonmagnetised magnetic material. Layer 5 is flexible and can be tin plated mild steel. Layer 6 laminated on the pposite side of layer 5 is of paper.

Alterna ively, the faces of the disc may be painted or coat d with a plastics material. A layer 7 on layer 6 provides a surface layer on the disc and can be formed of PVC. Layer 7 is provided where a decorative surface layer is required on the disc, and may be omitted.

Both the annulus 11 and disc 12 are sufficiently flexible to conform to a curved windscreen on a road vehicle. The disc and annulus have the same diameter, approximately 90 mm, and opening of the annulus has a diameter of approximately 75 mm. Both disc and annulus are thin. The thickness of layer 3 lies within the range 0.050 to 0.120 centimetres. The ratio of the area defined by the opening of the annulus to the area of a face of the disc lies within the range 1 3 to 1 6.

When a document is to be displayed, layer 1 is peeled from the annulus 11 and the adhesive surface of layer 2 is placed in contact with a surface of the screen on which a document is to be mounted. The disc 12 is then removed from the annulus and a document is placed and held within the opening of the annulus whilst exposed surfaces of layer 3 of the annulus and layer 4 of the disc are brought into face-to-face contact. The magnetic holding means comprising layers 3 and 5 then holds the disc and annulus together and prevents the document from sliding from the opening. The disc holds the document on the surface over a substantial surface area of the document, including a plurality of positions around the perimeter of the opening.

The disc is held on the annulus by magnetic attraction between the magnetised particles of the layer 3 and the magnetic material of layer 5. The strength of retention of the annulus on the surface is greater than the strength of magnetic attraction between disc and annulus. The document can be contained entirely within the opening of the annulus or can be interposed between respective surfaces of the disc and annulus.

In an alternative embodiment of the displayer, layer 3 of the annulus contains a magnetic nonmagnetised material and layer 5 of the disc contains magnetised particles. In a further alternative, both disc and annulus contain magnetic particles.

The annulus and/or the disc can be formed of a plurality of pieces. In particular, a more economic use is made of material where the annulus is formed of pieces cut from a sheet.

It will be apparent that an unlimited variety of shapes of first and second elements lie within the scope of the invention, and that the invention may be employed for a variety of uses. The invention can be used for retaining road fund licences on vehicle windscreens, for which purpose the embodiment of displayer herein described is intended.
