Definitions
- the invention relates to an arrangement for the locking of their coincident with their line of gravity axis ren vernavba ⁇ , display bodies provided with permanent magnet, in particular for hand controlled signal display devices, wherein inthe arrangement
- a base plate and OK - are provided around the display body, which is rotatable with its center of gravity and parallel to the base plate, whereby
- This display body with at least two in the display-side surface of the base plate, or in a parallel surface
- the magnetic axis of the permanent magnets located in the display bodies is perpendicular to the center line of the display bodies.
- the display bodies are designed to be rotatable and about the axis arranged in their center of gravity and after a rotation of 90 ' go from one to the other end position.
- a display body part Arranged between the two end faces of these display bodies is a display body part that fills the entire space, the middle or full width of which is designed as a permanent magnet. Because the magnetic fields that come about
- this type of display body is generally only used as a segment in segment display devices.
- These display bodies are also suitable for the rewriting of
- Hand controlled for example using a magnetic pen.
- the aim of the invention is to eliminate the lack of locking and to create locking means of this type which ensure the stability of the rewritten information satisfactorily.
- the basis of the invention is the inventive consideration that, in the case of a magnetic manual control (for example with a magnetic pen), the display bodies are locked in the end positions / ⁇ by means of soft iron elements which can be slid in the vertical direction to the base plate, preferably by means of slidable elements perpendicular to the base plate and rotatable permanent magnetic body can take place.
- the display body with permanent magnet suitable for locking the display body in the two end positions or magnetizable / s locking means are provided, furthermore o - the magnetic axes of the in permanent magnets located on the display bodies include an acute angle with the base plate.
- FIG. 1 represents a locking with soft iron plates
- FIG. 2 shows a locking with soft iron cylinders
- FIG. 3 shows a locking with permanent magnet ball.
- Display body 1 shown are prism-shaped and preferably rotatable about the 3 # axis 2 arranged in their center of gravity.
- One edge of the display body 1 is rounded and its two sides, which meet in the edge diagonally opposite the rounded edge, are designed as display surfaces 3a, 3b suitable for carrying information which deviates from one another.
- a permanent magnet is arranged in the interior of the display body 1, the magnetic axis 4 of which forms an angle, preferably a 5 angle of 45, with the two display surfaces 3a, 3b and extends perpendicular to the axis 2 of the display body 1.
- the axis 2 is arranged parallel to the base plate 5.
- the locking means is a soft iron plate 6, which is arranged at a distance of 5 "and which allows rotation of the display body 1, parallel to the base plate 5, the rolling surface of the display body 1 that can be brought into contact with the soft iron plate 6 being one with the axis 2 the indicator body 1 has a coincident axis with a cylindrical surface area.
- the indicator body 1 rotates counterclockwise so that the north pole comes close to the soft iron plate 6
- this arrangement only ensures the corresponding solution if the soft iron plate 6 continuously remains in contact with the display body 1 during the rotation, ie if the rolling surface of the display body 1 located between the edges of the two display surfaces 3a, 3b is in the form of a quarter of a cylinder jacket.
- FIG. 2 offers a remedy to this problem, where an opening 7 is provided behind each display body 1 on the side of the base plate 5 opposite the surface on the display side.
- a prism made of soft iron or a cylinder 9 is arranged in the opening 7 and is suitable for movement in the direction perpendicular to the display surface of the base plate 5 and loosely attaches to the wall 8 of the opening 7.
- This prism or this cy Linder 9 is - after which it can be pressed back - in constant contact with the display body 1 and lies in the peripheral positions of the display body 1 - apart from the rounding - with its entire surface on the display body 1.
- Locking means shown contains a permanent magnet with a magnetic axis parallel to the plane of the base plate 5, so the opening 7 is preferably also cylindrical and the locking takes place by rotating the cylinder through 180 ° about its own axis.
- a cylinder is also to be understood to mean a disk which has a considerably smaller height than its diameter, but it can also be another body which is suitable for turning in the opening 7, in particular a rotating body.
- the magnetic axis of the permanent magnet in the cylinder is perpendicular to axis 2. This example is not shown.
- 2 ⁇ rer be made if a permanent magnet is provided in the ball 10.
- the ball 10 provided with a permanent magnet magnetized in its diameter rotates about 90 * when the display body 1 is rotated by 90 and locks the display body 1 in its marginal positions.
- the magnetic axis 11 of the permanent magnet located in the ball 10 forms an angle with the plane of the base plate 5, namely an angle of approximately 45 * and runs perpendicular to the axis 2, ie it lies in a plane with the magnetic axis 4 of the permanent magnet located in the display body 1
