Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a diagram drawing toy capable of drawing a diagram of a plurality of patterns.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, there is known a drawing toy in which a writing instrument attached to the tip of a hollow case-shaped gripping portion vibrates (Japanese Utility Model Publication No. 52-131142 and Japanese Utility Model Publication No. 53-63943). When I try to draw a line with these drawing toys, the writing instrument is constantly vibrating, so a fine loop becomes a continuous line.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned diagram drawing toy merely draws a continuous line of fine loops, and cannot draw a diagram with a special pattern automatically.

The present invention is capable of automatically drawing a diagram of two or more types of patterns by switching operation, and manually moving the patterns by hand, similar to the case of handling an ordinary pen by hand. The purpose is to provide a diagram drawing toy that can be changed in various ways.

[0005]

[Means for Solving the Problems]

 The diagram drawing toy of the present invention has a rotating plate having a brush tip on the front side and a rotating shaft having a gear on the back side, and a rotating plate supporting means rotatably mounted at an eccentric position on the rotating shaft of the rotating plate. A rotation drive mechanism for rotating the rotating plate supporting means, a gear portion that meshes with a gear of the rotating shaft of the rotating plate, and a position that engages with the rotating plate supporting means and a position that does not engage with the rotating plate supporting means. A switching member movable between the rotating plate supporting means and the rotating plate supporting means when the rotating member is engaged with the rotating plate supporting means.

By using the diagram drawing toy of the present invention having such a configuration, it is possible to automatically draw a diagram of a plurality of special patterns by moving the switching member.

If the gear portion of the switching member has a plurality of gears with different numbers of teeth, three or more types of symbols can be automatically drawn by moving the switching member.

Also, when the gear of the rotation shaft of the rotation plate is composed of a plurality of gears having different numbers of teeth, three or more kinds of symbols can be automatically drawn by moving the switching member.

[0009]

[Action]

 According to the present invention, when the rotation plate supporting means, which is eccentrically attached to the rotation plate provided with the writing instrument, rotates, the writing instrument draws a circular path. Since the gear part of the switching member meshes with the gear attached to the rotation shaft of the rotation plate, when the switching member rotates integrally with the rotation plate support means, the rotation plate does not rotate and the circular orbit does not occur. Maintained.

When the switching member is moved to a position where it does not engage with the rotation plate supporting means, the switching member does not rotate. At this time, the gear pivotally attached to the rotating plate meshes with the gear part of the switching member, but this gear part does not rotate, so when the rotating plate support member rotates, it meshes with the stopped gear part. The rotating shaft gear moves in accordance with the rotation of the rotating plate supporting member, and thus inevitably rotates. As a result, the rotating plate revolves while revolving along with the rotating rotating plate support member. The orbit of the writing instrument becomes an ellipse or other geometrical figure due to the combination of the revolution and rotation of the rotating plate.

When the switching member is not rotating, a drawing defined by the ratio of the number of teeth of the rotation shaft gear of the rotating plate to the number of teeth of the gear portion of the switching member is drawn as the trajectory of the writing instrument. Therefore, by changing the ratio of the number of teeth, it is possible to automatically draw many kinds of designs.

[0012]

Embodiment FIG. 1 shows the appearance of an embodiment of the diagram drawing toy according to the present invention, FIG. 2 is an assembly drawing of the diagram drawing toy of FIG. 1, and FIGS. It is a partial longitudinal cross-sectional view shown.

As shown in FIG. 1, the diagram-drawing toy 10 is composed of a power supply switch 11 and a gripping portion 15 projecting the changeover switch 13 to the outside, and a writing member 17 projecting at the tip thereof. Two brush tips 19a and 19b are provided so as to project from the tip of the. The writing member 17 is eccentrically attached to the disc-shaped rotation plate 21. The rotating plate 21 is eccentrically attached to a circular member 23 provided at the tip of the grip portion 15. A cover 25 is provided at the tip of the grip portion 15, and tips of the writing tips 19a and 19b project from the cover 25.

Next, with reference to FIG. 2, an internal configuration of the diagram drawing toy 10 will be described.

The grip portion 15 is made of a tubular body in which an upper casing 15 a and a lower casing 15 b are joined with screws 77 and 79, and a hole 12 through which a power switch 11 having a conductive metal fitting 33 attached with a screw 34 protrudes and a changeover switch 13. Has a hole 14 protruding therefrom. A battery box 29 accommodating the battery 27 is provided at the rear end of the lower casing 15b. The battery box 29 is closed with a lid 31 and stopped with a screw 30.

A motor 35 is arranged in front of the battery box inside the grip portion 15, and a pinion 36 fixed to a rotation shaft of the motor 35 meshes with a first reduction gear 37. The reduction gear 37 meshes with the second reduction gear 39, and the reduction gear 39 meshes with the third reduction gear 41. The three reduction gears 37, 39, 41 are respectively supported by bearings provided inside the cylindrical member 42, and are housed inside the cylindrical member 42. The reduction gear 41 meshes with the gear 43. The motor 35 and the three reduction gears 37, 39, 41 constitute a rotary drive mechanism.

The gear 43 has a rim screwed to a rotary shaft (referred to as an orbital shaft) 48 of a circular member 47 in which a leg 24 protruding rearward of the circular member 23 located at the tip of the grip portion 15 is coupled with a screw 45. It is pivoted at 49. At the rear end of the circular member 47, four protrusions 46 for engaging with a protrusion 75 (see FIGS. 3, 4, and 5) provided inside the switching member 69 described later are projected. The circular members 23 and 47 and the gear 43 constitute a rotation plate supporting means.

As described above, in the embodiment, the rotating plate supporting means is provided with the two circular members 23 and 47 that rotate integrally, but if the rotating plate 21 is supported stably and firmly. However, it is not always necessary to provide two circular members, and the circular member 47 alone can sufficiently fulfill its function.

A writing member 17 having writing tips 19a and 19b is attached to the front surface of the rotation plate 21 at a position where either writing tip is eccentric. The writing member 17 has a structure in which bearings 16a and 16b, into which the shafts of the writing brush having the writing tips 19a and 19b are fitted, are attached by a fixture 20 by urging the bearings 16a and 16b with springs 18a and 18b, respectively. A shaft (referred to as a rotation shaft) 51 extending rearward from the back surface of the rotation plate 21 penetrates a hole 53 provided in the circular member 23 to pivotally mount a gear 55, and is rotated by a bearing 57 provided in the circular member 47. It is freely inserted and fastened with a rim screw 59.

The circular member 47 is arranged inside a cylindrical switching member 69 having an inner peripheral gear 65. A second inner peripheral gear 67 having a different number of teeth from the gear 65 is fixed inside the switching member 69. A gear 55 pivotally mounted on the shaft 51 of the rotating plate 21 meshes with the inner peripheral gear 65 or 67. A groove 71 is formed on the outer periphery of the switching member 69, and two projections 72 for engaging with a projection 83 of a locking member 81, which will be described later, project rearward from the rear end surface. Inside the switching member 69, a protrusion 75 for engaging with the protrusion 46 of the circular member 47 projects forward.

The switching member 69 is housed inside a cylindrical member 63 having a through hole 61 in the side wall thereof, and the projection 73 of the switch 13 is inserted into the through hole 61, and the projection 73 is provided on the outer periphery of the switching member 69. It fits in the provided groove 71.

The locking member 81 has a cylindrical shape, and is fixed by being sandwiched between the cylindrical member 42 and the cylindrical member 63. Inside the locking member 81, two locking projections 83 that engage with the projection 72 of the switching member 69 and lock the rotation of the switching member 69 are projected forward.

The cylindrical member 63, the locking member 81, the cylindrical member 42, and the motor 35 are housed in the grip portion 15, and the operation portion of the switch 13 projects to the outside from the hole 14 of the upper casing 15a. The cover 25 is fitted into the tip of the grip portion 15 so that only the tips of the writing tips 19a and 19b project outward.

Next, the operation of the diagram drawing toy 10 will be described with reference to FIGS. 3 to 5.

In FIG. 3, the changeover switch 13 is set to the most distal position A. When the power switch 11 is turned on, the motor 35 rotates the pinion 36, and this rotation is transmitted to the gear 43 via the reduction gears 37, 39, 41.

Since the gear 43 is attached to the revolution shaft 48, the circular members 23 and 47 rotate together with the gear 43 (hereinafter referred to as revolution). Therefore, the rotation plate 21 eccentrically attached to the circular member 23 revolves in a circle.

At this time, the switching member 69 revolves integrally with the circular member 47 because the protrusion 75 protruding inward is engaged with the protrusion 46 protruding rearward of the circular member 47. As a result, the gear 55 of the rotating shaft 51 moving on the revolving circular member 47 only moves by meshing with the inner peripheral gear 65 of the revolving switching member 69, and the rotating shaft 51 itself rotates (hereinafter, referred to as “rotating shaft”). Not called). At this time, the orbit of the brush tip becomes a circle as shown in Fig. 6 (A).

Next, as shown in FIG. 4, when the changeover switch 13 is moved to the center position B, the protrusion 73 of the changeover switch is fitted into the groove 71 provided on the outer periphery of the changeover member, and therefore the changeover switch 13 is turned off. The replacement member 69 also moves to the central position.

When the power switch 11 is turned on, the pinion 36 is rotated by the motor 35, and this rotation is transmitted to the gear 43 via the reduction gears 37, 39, 41.

Since the gear 43 is attached to the revolution shaft 48, the circular members 23 and 47 revolve integrally with the gear 43. Therefore, the rotating plate 21 eccentrically attached to the circular member 23 revolves in a circle.

The above is the same as the case where the changeover switch 13 shown in FIG. 3 is set to the position A at the most tip.

However, the protrusion 75 protruding inward of the switching member 69 is separated from the protrusion 46 protruding rearward of the circular member 47, and the protrusion 72 protruding rearward of the switching member 69 is locked inside the locking member 81. The switching member 69 is stopped while engaging with the projection 83.

The gear 55 attached to the rotation shaft 51 of the rotation plate 21 meshes with the inner peripheral gear 65 of the switching member 69, but since the inner peripheral gear 65 does not revolve, the circular members 23 and 47 revolve. Then, the gear 55 meshed with the stopped inner peripheral gear 65 is necessarily rotated because it needs to move together with the circular members 23 and 47. As a result, the rotating plate 21 revolves while revolving with the revolving rotating plate members 23 and 47.

The gear 55 has 24 teeth, and the first inner peripheral gear 65 has 48 teeth. The greatest common divisor of the number of teeth of the gear 55 and the inner peripheral gear 65 is 24, and the value obtained by dividing the number of teeth of the inner peripheral gear 65 by 24 is 2. As a result, the locus of the writing tip of the writing member 17 becomes the elliptical shape shown in FIG. 6 (B).

Next, as shown in FIG. 5, when the changeover switch 13 is moved to the rearmost position C, the projection 73 of the changeover switch is fitted in the groove 71 provided on the outer periphery of the changeover member 69. The switching member 69 also moves to the rearmost position. At this time, the gear 55 of the rotation shaft 51 of the rotation plate 21 meshes with the second inner peripheral gear 67 of the switching member 69.

When the power switch 11 is turned on, the motor 35 rotates the pinion 36, and this rotation is transmitted to the gear 43 via the reduction gears 37, 39, 41.

Since the gear 43 is attached to the revolution shaft 48, the circular members 23 and 47 revolve integrally with the gear 43. Therefore, the rotating plate 21 eccentrically attached to the circular member 23 revolves in a circle. The projection 75 projecting inward of the switching member 69 is separated from the projection 46 projecting rearward of the circular member 47, and the projection 72 projecting rearward of the switching member 69 serves as a locking projection 83 inside the locking member 81. The switching member 69 is engaged and stopped. The above is the same as when the changeover switch 13 shown in FIG. 4 is set to the central position B.

That is, the gear 55 attached to the rotation shaft 51 of the rotation plate 21 meshes with the inner peripheral gear 67 of the switching member 69, but the inner peripheral gear 67 does not revolve, so that the circular members 23 and 47 are When revolved, the gear 55 that meshes with the stopped inner peripheral gear 67 is necessarily rotated because it needs to move together with the circular members 23 and 47. As a result, the rotating plate 21 revolves while revolving with the revolving rotating plate members 23 and 47.

However, the gear 55 attached to the rotation shaft 51 of the rotation plate 21 meshes with the second inner peripheral gear 67 of the switching member 69. The gear 55 has 24 teeth, and the second inner peripheral gear 67 has 50 teeth. The greatest common divisor of the number of teeth of the gear 55 and the inner peripheral gear 67 is 2, and the value obtained by dividing the number of teeth of the inner peripheral gear 67 by 2 is 25. As a result, the trajectory of the brush tip becomes the floral pattern with 25 petals shown in FIG. 6 (C).

Although the embodiment has been described above, the present invention is not limited to the above embodiment, and various design changes and addition of a new configuration are also included in the scope of the present invention. For example, the tip of the brush may be one, or three or more. It is also possible to change the design drawn by the combination of gears to be engaged by setting the number of gears attached to the rotation shaft of the rotating plate to two or more and the number of gears of the switching member to one or two or more.
