Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to a fastening device for display sheets, projection screen sheets of overhead projectors, etc. For magnetic materials and magnetic plates,
A locking device that can be displayed almost flat and high in a protruding state.

[Prior art] As a holding device for this type of exhibition sheet, etc., it has been used for a long time to attach a paper or sheet to a magnetic board (magnetic blackboard or white board) using a holding device that has a magnet to sandwich the paper or sheet and magnetically attract it to the magnetic board. It was parked and displayed.

Also, items other than magnetic plates were fixed with thumbtacks or cellophane tape.

[Problems to be solved by the invention] In the conventional technology described above, the upper part of the display sheet or paper is attracted to a magnetic board using a magnet, and the sheet or paper is hung on the surface of the magnetic board for display. Because the area covered by the display sheet or projection screen makes it impossible to write on the magnetic blackboard or whiteboard, which wastes space and is uneconomical, the height of the magnetic blackboard or whiteboard is too high. Since the sheet, paper, and projection screen can only be displayed in front of the display, there is a problem in that those who are far away can't clearly see the information on the display sheet or the contents projected on the screen sheet because the head of the person in front of them is obscured.

In addition, the same problems as those described above occurred with devices that were fastened with thumbtacks or cellophane tape.

In order to eliminate each of the above-mentioned problems, this invention requires that the display sheet or projection screen be protruded from the top or side of the magnetic blackboard or whiteboard via support arms, and be placed almost flat, vertically or diagonally. The purpose is to display it as highly as possible.

[Means for Solving the Problems] The purpose of this invention described above is to provide a base having a magnet, a support arm protruding from the base, and a sheet holding piece formed at the tip of the support arm. is achieved.

A self-closing clip member may be attached to the base, the support arm may be made of a transparent material, and a scale may be provided on the support arm.

Furthermore, by employing an overhead projector or a projection screen in a projection television receiver as an exhibition sheet, it becomes a locking device for locking an exhibition sheet for simultaneous viewing by a large number of people.

[Function] The lower part or one side of the display sheet or paper can be magnetically attracted and localized to the magnetic blackboard or whiteboard by the magnetic force of the magnet provided at the base of the holder, and the display protruding from the magnetic board can be fixed. For exhibition purposes, the top and other sides of the display sheet and projection screen sheet can be held by holding them with the sheet holding pieces provided at the end of the support arms protruding from the base, thereby protruding outward from the magnetic blackboard or whiteboard. Sheets, paper, and other screen sheets can be displayed vertically or tilted at a predetermined angle without sagging due to their own gravity.

In addition, to use the locking device of this invention on a wooden board other than a magnetic board, attach two or three magnetic thumbtacks to the wooden board, and attach magnet 1 to the thumbtacks to attach it to a very ordinary wooden blackboard or white board. It is also possible to display the display sheet by protruding it from the top and positioning it in a fixed position.

[Example] Examples will be described with reference to the drawings.

As shown in FIG. 1, this invention generally consists of a base 2 made of, for example, plastic molding, having a magnet 1, a support arm 3 protruding from the base, and a sheet formed at the tip of the support arm 3. Each of the holding pieces 4 is provided with a holding piece 4.

As shown in Fig. 2, this idea is based on a magnetic board 7 such as a magnetic blackboard or white board, with an exhibition sheet 8 sandwiched between the upper front or left front, and a magnet 1 attached to the base 2.
The display sheet 8 is fixed with the support arm 3 and the upper or left side of the display sheet 8 is held by the sheet holding piece 4 for display use.

A more specific structure of the display sheet fastener is as shown in FIG. 3, for example, a plastic base 2
At the same time, a support arm 3 having a sheet holding piece 4 at the tip is integrally molded to the base 2, and the magnet 1 is attracted to the magnetic plate 7 with the exhibition sheet 8 sandwiched therebetween. The protruding edge of the display sheet 8 is held between the holding pieces 4 and held in place, so that the protruding part of the display sheet 8 can be displayed in an upright state without sagging due to gravity.

In addition to paper or sheets, the display sheet 8 may also be a screen sheet of an overhead projector or a projection screen of a projection television.

The embodiment shown in FIG. 4 has five circular magnets 1.
In the embodiment shown in FIG. 5, a circular magnet 1 is fitted into a square base 2, and in the embodiment shown in FIG. A circular magnet 1 is fitted.

In the embodiment shown in FIGS. 7, 8, and 9, a rectangular magnet 1 is bonded to one side of the base 2, and a self-closing clip member 5 with a spring is attached to the other side of the base 2. One side of the exhibition sheet 8 folded back onto something other than the magnetic plate with the clip member 5 can be oriented, and the other protruding side can be oriented with the holding piece 4.

In addition, in each of the above embodiments, the base 2 and the support arm 3
The sheet holding pieces 5 and 5 may each be made of transparent or opaque plastic or light metal such as aluminum, and the magnet 1 may be made of a rubber magnet and adhered to the base 2.

Further, if a scale graduation 6 is attached to the support arm 3 as shown in FIG. 1, it can be used as a ruler or a scale.

If the state shown in FIG. 3 is viewed from the right side of the figure, the display sheet 8 will not be in the shadow of the support arm 3, and almost the entire surface can be seen evenly.

[Effects of the invention] Since this invention is configured as explained above, it produces the effects described below.

In the anchoring device for display sheets and the like according to claim 1, the lower part or one side of the exhibition sheet or paper can be magnetically attracted and localized to a magnetic blackboard or whiteboard using the magnetic force of the magnet provided at the base of the anchoring device. By holding the top and other sides of the exhibition sheet or projection screen sheet that protrudes from the magnetic board with the sheet holding piece provided at the end of the support arm that protrudes from the base, the magnetic blackboard can be created. Display sheets and screens protruding from the white board can be displayed vertically or tilted at a predetermined angle without sagging due to their own gravity.

Therefore, the blackboard or whiteboard can be used to its fullest, so there is no shortage of space for writing, and because the paper or projection screen sheet can be protruded above the blackboard and displayed high, it is possible to display the display sheet or projection screen sheet reliably even from a distance. This has the effect of allowing you to see the written and projected contents.

According to claim 2, in addition to the above-mentioned effects, the exhibition sheet can be orientated in a state where it protrudes into a non-magnetic object.

In claim 3, the contents written on the display sheet on the back side of the support arm can be seen through the transparent support arm.

According to claim 4, the length can be measured using the scale graduation 6,
It has the effect of being able to be used as a ruler or measuring stick.
