RU72565U1 - MAGNETIC DEMO BOARD - Google Patents

Abstract

A magnetic display board refers to devices for attaching removable elements and can be used as a teaching aid in schools and circles of young technicians to demonstrate various information. The device comprises metal plates 1 mounted on a web 2 fixed in rigid planks 3 and provided with one support point 5. The blade 2 is made of soft material. Permanent magnet 7 is freely located on the held element 6. The metal plate is made of steel. The technological capabilities of the device are expanded by moving the held element in any direction in the plane of the screen canvas.

Description

The utility model relates to attachment devices for removable elements and can be used as a teaching aid in schools and circles of young technicians to demonstrate various information.

Known magnetic device according to patent US 4258493, IPC G09F 7/00, publ. 1981.03.31, containing magnets, a retained element, a spring, and a holder. A disadvantage of the known device is the inability to move the held element either horizontally or vertically due to the fact that the holder is stationary, rigidly fixed on a vertical plane.

Also known magnetic device according to patent EP 0029500, IPC G09F 1/10, publ. June 6, 1981, containing a magnet mounted rotatably. metal plate, held element and bar. A disadvantage of the known device is the inability to move the held element vertically, since the bar on which

mounted device, rigidly fixed in horizontal position.

The prototype closest to the claimed utility model in terms of essential features is a magnetic fastener according to patent RU 2127906 C1, 6 G09F 7/04, publ. 1999.03.20, containing magnets and plates. The design is suspended on a stationary horizontal string, which allows you to fix the held element relative to the string with the possibility of its movement only in the horizontal direction. The disadvantage of this device is the inability to move the held element vertically.

The proposed utility model solves the problem of expanding the technological capabilities of the device by moving the held element in any direction in the plane of the canvas.

To achieve the indicated technical result, in a magnetic demonstration board including a permanent magnet and metal plates, the latter are mounted on a web fixed in rigid planks and provided with one support point, the web being made of soft material, and the permanent magnet is freely movable on the held element on the canvas. Metal plates are made of steel.

Distinctive features of the proposed device is the installation of metal plates on the canvas, fixed in rigid planks and provided with one point.

support, and the canvas is made of soft material, and a permanent magnet is located on the held element with the possibility of free movement on the canvas, while the metal plates are made of steel.

Due to the presence of these signs, it became possible to move the held element in any direction along the web, which expands the technological capabilities of the device, and the presence of steel enhances the attraction of magnets.

The essence of the utility model is illustrated by the drawings:

- figure 1 shows a General view of the device;

- figure 2 is a view of the device in section.

A comparative analysis of the proposed design with analogues and prototype showed that the proposed device "Magnetic demonstration board" meets the criterion of "novelty."

The proposed utility model meets the criterion of "applicability", as it is manufactured, tested and widely used in schools and circles of the Station for Young Technicians.

The magnetic display board is a screen containing small steel plates 1 glued to a soft cloth 2 made of dense textile material. In the upper and lower parts of the canvas 2 is fixed in wooden planks 3. On the upper plank 3 is attached a cord 4 for hanging the device at the pivot point 5. The pivot point 5 can be located, for example, on a wall or stand. The held element 6 is, for example, a sheet of paper with different

information that is attached to the screen with a strong patch permanent magnet 7.

The operation of the device.

The steel screen is suspended on a cord 4 at the fulcrum 5, a sheet of paper 6 with information is applied to the steel plates 1 and pressed with a magnet 7.

As a holding member, various paper figures that can be moved in can be used. different direction on the screen. The device can be used as a bulletin board. In addition, the design of the screen allows you to roll it into a roll for easy transportation, for example, transfer from the premises of one school class to another. The device can be used in field conditions, during competitions, excursions, to indicate routes where tree branches serve as a fulcrum. Several magnets can be used simultaneously for various figures, demonstrating their movement.

Claims (2)
