Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a three-dimensional stamp for a magnetic drawing board, and more particularly to a three-dimensional stamp for a magnetic drawing board comprising a three-dimensional stamp body and a movable stamp piece.

Generally, it is known that when a permanent magnet is brought close to a member containing viscous flow and iron powder from the outside, the permanent magnet will attract the iron powder inside the member. A part of the iron powder 12 enclosed in the honeycomb-shaped member 11 is a permanent magnet piece 1 in contact with the upper surface 11a of the member 11.
3 and appears on the upper surface 11a of the member 11 so that it can be seen from the outside.
4 and disappear from the upper surface 11a of the member.If the stamp impression or pen shaft is made of a permanent magnet, a drawing board using magnetism can be constructed, and various magnetic drawing boards have been proposed and implemented. has been done. Conventionally, the magnetic stamps used on this type of magnetic drawing board are made by fixing permanent magnet pieces with various impressions on the stamp surface, and such fixed stamps print the same figure on the magnetic drawing board. etc. could be expressed repeatedly, but there was little variation.

In response to this, the present invention aims to propose a three-dimensional stamp for a magnetic drawing board that allows the stamping action itself to be enjoyed, and that can bring further expansion and variety to stamp play by combining the shape of the stamp body with the stamp.

Embodiments of the present invention will be described below with reference to the drawings.

2 and 3, reference numeral 1 denotes the stamp body, which is shaped like a bus, and the portion of the stamp body 1 corresponding to the bus door on its side is formed as a movable stamp piece 2 which can freely rotate downward within an angle of about 90 degrees. A permanent magnet piece in the shape of a passenger is attached to the outer surface of the movable stamp piece 2 to form the stamp surface 3.
The lower end of the stamp piece 2 is pivotally attached to the stamp body 1, and is normally arranged on the side of the stamp body 1 like a door for ascending and descending, but when stamping, it rotates downward so that the stamp surface 3 forms approximately the same plane as the lower end surface of the stamp body 1. For this purpose, for example, as shown in FIG. 3, the stamp body 1 is attached to a frame member 1 constituting the outer part of the bath.
A spring 4 is interposed between the stamp piece 2 and the base piece 1b constituting the wheel and chassis, and the relative positions of the two are changed by pushing down the frame member 1a from above, so that the base piece 1b is hidden inside the frame member 1a. Meanwhile, the lower end of the stamp piece 2 is pivotally attached to the lower end of the frame member 1a so as to be freely rotatable, as shown in Figs. 4a and 4b, and an L-shaped bent engagement piece 6 is formed near the lower end of the stamp piece 2. In normal times, as shown in Fig. 4a, the engagement piece 6 engages with the base piece 1b, so that the stamp piece 2 is kept approximately flush with the side surface of the stamp body 1, and the engagement is released when stamping. The pivot part 5 of the stamp piece 2 is provided inside the center of the stamp piece 2. With this configuration, when the stamping action is performed by pressing the frame member 1a of the stamp body 1 downward, the base piece 1b rises relatively as shown in Fig. 4b, and the engagement between the engagement piece 6 of the stamp piece 2 and the base piece 1b is released. Since the pivot 5 of the stamp piece 2 is located inside the center of the stamp piece 2, the release of the engagement causes the stamp piece 2 to rotate outward. At this time, the stamp surface 3 becomes approximately flush with the lower end surface of the frame member 1a. Therefore, by performing the above-mentioned stamping operation on the magnetic drawing board (shown by the dashed line in FIG. 4), the stamp piece 2
The stamp body 1 is rotated and pressed against the magnetic plate, and the passenger's figure 8 is stamped on the plate. Next, when the force applied to the stamp body 1 is released, the base piece 1b moves to the fourth position.
The state returns to that shown in FIG. 1A, and at this time the engagement piece 6 of the stamp piece 2 engages with the base piece 1b and rotates again in the opposite direction, returning to the original state.

Note that the rotational configuration of the movable stamp piece 2 is not limited to the example illustrated above. Other known means may be used, such as keeping the movable stamp piece 2 biased toward the stamp body 1 side by a spring at all times, and rotating the stamp piece 2 against the spring pressure by the stamp operation. The movable stamp piece may be provided not only on one side of the stamp body but also on other sides. FIG. 5 shows an example in which a movable stamp piece 2 is provided on the rear surface of the stamp body 1, and this stamp piece 2 is formed with a permanent magnet stamp surface 3 in the shape of a bus stop.
Further, a plurality of movable stamp pieces may be provided in a single stamp body, and in this case, each stamp piece may be configured to be selectively movable. Furthermore, it is also possible to form a fixed stamp surface on an appropriate surface of the stamp body 1.

According to the above-mentioned three-dimensional stamp, for example, a road and several bus stops are drawn on a magnetic drawing board with a magnetic pen, and the bus-shaped stamp body 1 is run on the road and a stamp operation is performed at each bus stop. You can stamp the shapes of passengers on the bus and calculate the total number of passengers, or decide in advance the number of passengers on the bus and determine the number of passengers remaining on the bus based on the number of stamps stamped at each bus stop. It can also be expected to have educational effects such as calculating the number of passengers, and instead of simply enjoying the stamp shape pressed on a magnetic drawing board as in the past, in addition to this, you can enjoy the stamp operation itself, and the stamp itself. In this example, the concrete shape of a bus is given to the stamp, so the combination of the picture drawn on the magnetic drawing board, the stamped figure, and the stamp body can expand the play with stamps into something varied.

In addition, as mentioned above, it is preferable to form a seal related to the stamp body on the stamp surface.
There is no need to be particularly limited, and the stamp body may have three-dimensional shapes such as animals, plants, Kyoto scientific bodies, etc. in addition to vehicles.

Furthermore, the above-mentioned three-dimensional stamps are
You can play with 3D stamps of various shapes as shown in the figure below. The stamp 16 shown in FIG. 1A is modeled after a passenger car, and has a stamp surface 18 made of a tread-shaped permanent magnet formed on the outer surface of a rotatable tire member 17. The stamp 16 shown in FIG. This allows the tread pattern 8 to be stamped. Further, the stamp 19 shown in FIG. 1B is made to imitate a locomotive, and the driving wheel member 20 of the stamp 19 has a stamp 21 of an endless track representing sleepers and railroad tracks formed of permanent magnet pieces as shown in FIG. has been done. Therefore, by running the stamp 19 over the magnetic drawing board, the track-like figure 8 can be stamped.
By combining the above-mentioned stamps with these stamps, playing with stamps can be made even more fun.

As explained in detail above, the three-dimensional stamp for magnetic drawing boards according to the present invention has a movable stamp piece on the stamp body, and when stamping, the movable stamp piece is operated to stamp on the magnetic drawing board. The stamp action becomes fun and interesting, and by combining the stamped figure and the shape of the stamp body, as well as pictures, letters, or other stamps on the magnetic drawing board as appropriate, you can change and expand the stamp play. can.
