Description

[Detailed description of the invention] [Field of industrial application] The present invention is a toy that has a mechanism for rotating a doll or the like as a part of its structure, or has a performance mechanism such as a music box that is activated by pressure. The present invention relates to a drive mechanism in a store and a toy using the drive mechanism.

[Prior Art and its Problems] It is conventionally known to attach a doll or the like to a part of a toy and to rotate the doll.

In such a mechanism, for example, a mechanism similar to the mechanism illustrated in FIG. 11 and a simplified version thereof is known as a mechanism for rotating the doll.

That is, they include a crown gear for rotation in which a shaft for supporting an object to be rotated stands up from the center, and a crown gear whose central part in the length direction is supported by the shaft and whose tip end is the above-mentioned crown gear. The rotary drive arm is configured to rotate and oscillate in the horizontal direction while meshing with the teeth of the rotary drive arm. When performing horizontal reciprocating motion, especially horizontal rocking motion in the forward direction, the tip of the rotational drive arm pushes the occlusal section of the crown gear (by moving the pieces) and rotates it by a predetermined angle. It is known as a structure that allows

However, in the case of the above-mentioned known structure,
Since the rotary drive arm is configured to always maintain a horizontal state, the tip of the arm, which swings horizontally (reciprocating motion) to feed the frame, rotates the crown gear by a predetermined angle. Later, when attempting to swing to return to the original position, the tip of the arm engages with the teeth of the crown gear, creating strong frictional resistance between it and the gear that it attempts to climb over. This often resulted in a malfunction in which the crown gear rotated in the opposite direction, when it should have simply been necessary to get over it.

For this reason, in conventional mechanisms, in order to prevent the crown gear from reversing, it is necessary to separately provide a stopper mechanism for preventing reversal in addition to the rotation mechanism using the arm mentioned above on a part of the crown gear, making the entire structure complicated. It had the disadvantage of becoming

[Purpose of invention]

The present invention is intended to cope with the above-mentioned circumstances. That is, in the present invention, the tip of the rotary drive arm that rotates the crown gear contacts and engages with the crown gear only when rotating and oscillating the crown gear, and otherwise engages in contact with the crown gear. It is an object of the present invention to provide a drive mechanism for rotation, etc. in a toy configured to be able to swing while drawing a trajectory without causing any movement, and a toy using such a drive mechanism.

Another object of the present invention is that there is no need to provide a mechanism for preventing the crown gear from reversing in the rotating mechanism, and the structure is extremely simple and can be manufactured at low cost. The purpose is to provide mechanisms and toys using these drive mechanisms.

[Key points of the idea]

The present invention consists of a rotary plate consisting of a bottomed cylindrical crown gear with a slightly raised peripheral edge and a serrated gear engraved on the raised part, a central part in the longitudinal direction that is pivotally supported, and both end portions A rotary drive arm configured to be able to swing vertically and horizontally, and configured such that when the distal end portion is lowered, the distal end portion engages with the gear of the rotary plate to rotate it. and an actuating plate that comes into contact with the rotary drive arm and operates to swing both end portions of the rotary drive arm in the vertical and horizontal directions, and the rotary drive arm includes:
Due to the contraction force of the spring, its tip is constantly pulled up in the direction away from the rotating plate, and
A drive mechanism for rotation, etc. in a toy configured to be biased with a force in a direction opposite to the rotational direction of the rotary plate, and this drive mechanism in the toy or main body consisting of a base and a lid. devised a toy structure in which an operating body for operating the operating plate from outside the toy or the main body is attached to the toy or the main body, and the rotating plate is connected to a rotating body such as a doll protruding from the lid body. The main points are as follows.

〔Example〕

Embodiments of the present invention will be described below with reference to drawings of a musical instrument toy operated by pressing a keyboard.

The toy or main body generally indicated by A is composed of a shallow box-shaped base 1 and a lid 2 attached to cover the top surface of the base 1.

3...3 is a keyboard, the tip of which is loosely sandwiched between the base 1 and the lid 2 so as to be able to swing, and the back surface near the base is attached to the base 1. By being supported by the band-shaped sponge body 4, it is possible to move up and down freely within the range of the contraction dimension of the sponge body 4 when pressed. (See Figures 2 and 9.) Reference numeral 21 denotes an edge plate formed inwardly on the peripheral edge of the lid body 2, and is attached to the upper surface of the base end of the keyboard 3 supported by the sponge body 4. By bringing them into contact with each other, the base end portions of the keyboards 3 . . . 3 are prevented from coming off from the lid body 2 . (See Figure 2).

Reference numeral 5 designates an operating plate for pressing the operating lever 61 of the music box 6 and driving the rotary drive arm 8, and is designed to cover the lower surface of the keyboard 3...3, and has an axis at the center of both ends. By supporting it, both the front and rear ends are attached so that they can freely swing in the vertical direction.

The actuating plate 5 described above is formed to have a substantially horizontal rectangular shape, and by placing the center portions of both ends thereof on a supporting plate 11 protruding from the base 1, the actuating plate 5 is centered at the supporting portion. The front and rear ends are configured so that they can move vertically in opposite directions, and the rear long side 51 of the actuating plate 5 is in contact with the lower surface of the keyboard 3...3, and the front long side The side 52 is brought into contact with the lower surface of the operating lever 61 of the music box 6.

Music box 6 fixed and attached on base 1
is known as a "single-frame feed music box," and by pressing (lifting) the operating lever 61 once, the drum 62 is rotated by a predetermined angle (one frame). 6
plays a short melody.

Further, when the operating lever 61 of the one-frame feed music box 6 is pressed continuously, the music box 6 described above can play one continuous melody.

Reference numeral 53 denotes a drive protrusion for driving the rotary drive arm 8, which is protruded above one end of the actuating plate 5 so as to have a triangular side surface. A cutout side 81a formed in the base end of the arm 8 can be contacted so as to be freely accessible and detachable. (See Fig. 11) As illustrated in detail in Fig. 6, the rotational drive arm 8 is constructed by forming a V-shaped notch near the base end of a rod made of a narrow flat plate. In addition to forming a notch side 81a, a chevron-shaped occlusal ridge 81b (sawtooth occlusal ridge) that is inclined only in one direction is formed at the tip, and a pivot 82 is fitted in the central portion in the longitudinal direction. A hole 81c is bored.

Note that the formation of the V-shaped notch 81a at the base end of the rotary drive arm 8 is not essential to the present invention; for example, the base end of the rotary drive arm 8 is It is also possible to form the plate-like body as a normal plate-like body without a base end, and to contact the inclined side 53a of the drive protrusion 53 formed protrudingly on the actuating plate 5 around the base end of the plate-like body.

The rotational drive arm 8 is pivoted at its longitudinal center on a pivot shaft 82 so that both end portions sandwiching it rotate in left and right directions in opposite directions.

In addition, when both ends of the rotational drive arm 8 rotate in the left and right directions about the pivot shaft 82, the two ends can also freely swing in the vertical direction at the same time. It is attached to a pivot 82.

As illustrated in FIGS. 6 and 7, a structure for swinging both ends of the rotary drive arm 8 in the vertical and horizontal directions as described above is a structure provided by a fitting provided in the rotary drive arm 8. The hole diameter of the fitting hole 81c is formed to be slightly larger than the outer diameter of the pivot shaft 82, and the height of the pivot shaft 82 is determined depending on the plate thickness of the rotary drive arm 8 (particularly, the diameter of the drilling portion of the fitting hole 81c). plate thickness)
This can be achieved by configuring the device to have slightly larger dimensions. That is, with this configuration, both ends of the rotary drive arm 8, which is loosely supported on the pivot shaft 82, can freely swing in the vertical direction and swing in the horizontal direction. become.

Note that the means for attaching the rotary drive arm 8 to the pivot shaft 82 is not limited to this.
For example, as illustrated in FIG. 8, the head of the pivot shaft 82 may be formed into a hemispherical shape, and the corresponding fitting hole 81c of the rotational drive arm may be formed as a hemispherical concave hole. Any structure is acceptable as long as it can achieve the purpose of swinging both ends of the rotary drive arm 8 in the vertical and horizontal directions. do not have.

A fixing screw 83 prevents the rotary drive arm 8 from coming off the pivot shaft 82.

Furthermore, the structure for driving the rotary drive arm 8 is not limited to the structure described above (as illustrated in FIGS. 2 to 11), but may have a completely opposite structure, For example, as illustrated in FIG. 12, a drive piece having an inclined side 53a formed on one side is formed at the end of the rotary drive arm 8, and a drive plate a is protruded from the actuating plate 5 at a position corresponding to this. You are also free to configure it.

Furthermore, the actuating plate 5 can also be constructed as a mechanism that performs simple vertical movement, in addition to the one in which the front and rear portions move up and down by rocking as in the illustrated example structure.

84 is a spring inserted between the rotational drive arm 8 and the cover plate 2;
, in particular, the part that is closer to the serrated drive protrusion 81b from the part of the fitting hole 81c that fits with the pivot 82, is constantly pulled up toward the cover plate 2, and the rotary drive arm 8 is moved toward the rotary plate 7. It is attached by being biased so that it is pulled back in the opposite direction to the direction of rotation.

The spring 84 described above can also be attached closer to the proximal end than the pivot 82 to which the rotary drive arm 8 is attached. However, in this case, the force applied to the spring 84 is in the opposite direction to that described above.
That is, the part near the base end from the position of the fitting hole 81c that fits with the pivot shaft 82 is pulled down toward the constant operating plate 5, and the rotational drive arm 8 is moved in the opposite direction to the rotational direction of the rotating plate 7. It is necessary to urge it to pull back.

Reference numeral 85 denotes a stopper, which regulates the retraction limit of the rotary drive arm 8 pulled back by the spring 84.

The rotating plate 7 includes a base plate 71 consisting of a bottomed cylindrical crown gear with a slightly raised peripheral edge and a serrated gear 71a engraved on the raised part, and a rotating shaft protruding upward from the center of the base plate 71. 72 is formed into an inverted T-shape, and the rotating shaft 72 portion is rotatably inserted through the center portion of the base plate 22 formed on the cover plate 2, and then the upper end portion is inserted into the upper surface of the base plate 22. expose,
A doll 9, etc. is attached to this exposed part.

The doll 9 described above is merely an example, and any doll that can interest young children by rotating may be used.

Serrated teeth 71a carved on the peripheral edge of the substrate 71
This allows the drive arm 8 to engage with a drive protrusion 81b formed at its tip when it horizontally swings in the forward direction.

In the figure, reference numeral 10 denotes a protective crown made of transparent synthetic resin or the like in the shape of an inverted bowl, and is attached to the cover plate 2 so as to cover the doll 9, thereby protecting the doll 9 from external shocks. ing.

[Operation of the idea]

The present invention configured as described above operates as follows.

* Playing the music box First, press any of the keys 3...3,
The keyboard 3 supported from below by the sponge body 4 descends.

When the keyboard 3 descends, the rear long side 51 of the actuating plate 5, which is attached to the lower surface of the keyboard so as to be able to swing vertically, is pressed and descends. The front long side 52 side located on the side rises.

Since the operating lever 61 of the music box 6 is located above the long side 52 on the front side of the operating plate 5, as the long side 52 rises, the operating lever 61
is now pressed from below, and this causes the music box 6 to be driven by one frame to play.

By repeating the pressing and releasing operations of the keys 3...3, the pressing of the operating lever 61 of the music box by the operating plate 5 is also repeated, thereby allowing the music box 6 to play one continuous melody. It becomes like this.

* Rotational movement of the doll The vertical swinging of the actuating plate 5 caused by the above-mentioned pressing operation of the keyboard 3...3 causes the music box 6 to play, and also causes the music box 6 to be played using a musical instrument formed protrudingly formed integrally on the end of the actuating plate 5. The driving protrusion 53 is also raised.

As the drive protrusion 53, which has a triangular side surface, rises, the inclined side 53a of the drive protrusion 53 comes into contact with a notch 81a formed at the end of the rotary drive arm 8.

As already described in detail, both ends of the rotary drive arm 8 are attached to the pivot shaft 82 so that it can move up and down in the vertical direction and swing in the left and right directions in parallel. The force causes the tip of the rotational drive arm 8 (occlusal projection 81b
part) is always pulled upward and is urged to be pulled back in the direction opposite to the rotating direction of the rotary plate 7, so that the inclined side 53a of the drive protrusion 53 protruding from the upper end of the actuating plate 5 Before contacting the rotary drive arm 8, the tip thereof is tilted forward as shown by the two-dot chain line in FIG. (See the solid line portions in FIGS. 2, 4, 13a, and 14a) When the rotary drive arm 8 in the above state comes into contact with the notch side 81a of the inclined side 53a of the drive protrusion 53, At this position, first the rotational drive arm 8
The proximal end of is lifted upward. As a result, the serrated occlusal projection 81b at the tip located on the opposite side descends and engages with the serrated gear 71a formed on the peripheral edge of the rotary plate 7.

In this case, the rotational drive arm 8 has not yet rotated. (See the solid line in Figure 4, the dashed-double line in Figure 13b, and the chain double-dashed line in Figure 14a) The rotary drive arm 8 has an occlusal protrusion 81b at its tip
Further lowering is stopped by the engagement of the part with the serrated teeth 71a of the rotary plate 7.

In this state, if the actuation plate 5 continues to rise (the drive protrusion 53 rises), the rotational drive arm 8
can now be moved (rotated) in the horizontal direction along the inclined side 53a of the driving protrusion 53, and the movement is performed by the distance of the inclined side 53a. (In other words, the movement is performed only within the allowable range of the swing angle of the actuating plate 5.) The above-mentioned movement (rotation) of the rotary drive arm 8 also rotates the rotary plate 7 that is interlocked with the rotary drive arm 8. The doll 9 attached to the upper surface of the plate 7 rotates on the base plate 22.
(See the two-dot chain lines in Figures 11, 13c, and 14b.) After rotating the rotary plate 7 (rotating the doll 9), the actuating plate 5 will move when the pressure is released (keyboard 3). When the pressure is released) the drive protrusion 53 and the rotation drive arm 8
The contact with the cutout side 81a formed in the cutout side 81a is also immediately released.

The rotary drive arm 8 released from contact with the inclined side 53a of the drive protrusion 53 has its tip (occlusal protrusion 81b) lifted upward in that position by the upward contractile force of the spring 84. As a result, the occlusion with the rotary plate 7 is released and the body returns to its original position. (See the two-dot chain lines in FIGS. 13a and 14c.) Thereafter, the same operation is repeated by repeating the above-described operation.

The swing locus of the tip (occlusal ridge 81b) of the rotary drive arm 8 described above is a triangular movement that moves in the order a→b→c in FIG. 13.

That is, the tip of the rotary drive arm 8 in the state a in the stopped state draws a trajectory toward b by swinging the rotary drive arm 8 in the vertical direction, and then draws a trajectory toward b in the horizontal direction of the rotary drive arm 8. The rotational drive arm 8 moves to c by swinging.
By opening the actuating plate 5, a trajectory toward a is drawn.

[Effect of idea]

The effects of the present invention configured as described above are as follows.

(1) Conventional rotary drive mechanisms were constructed in such a way that the rotary drive arm and the crown gear, which was a rotary plate, were always in mesh with each other. Since there was a risk that the crown gear 7 would rotate in the opposite direction at the same time, it was necessary to add a mechanism to prevent the gears from rotating in the opposite direction. Drive arm 8
is pivotally attached to the pivot shaft 82 so that its both ends can swing in both the vertical and horizontal directions, so that the tip of the rotational drive arm 8 drawn by swinging (occlusal ridge 81b) The locus of the rotor moves in a triangular shape, and the rotary plate 7, which is a crown gear, is configured to come into contact only when the rotary plate 7 is being rotated, so it is necessary to add a mechanism to prevent reverse rotation. is completely gone,
We were able to create an extremely simple configuration.

(2) The triangular drive protrusion 53 protrudingly formed on the end of the actuation plate 5 contacts the notch side 81a formed in the rotary drive arm 8 to rotate the rotary plate 7. With this structure, rotation can be performed extremely accurately, and a toy rotation mechanism with extremely high precision can be provided.

(3) Since the number of parts used can be extremely small, it is economical as it can be provided at a low price.

(4) Since the doll 9 on the rotary plate 7 can be rotated by the simple operation of pressing the keyboard as an operating body, even young children can easily rotate the doll.

(5) Since the manual music box 6 is attached so as to be in contact with the operating plate 5, the rotation of the doll can be linked with the music of the music box, which can further interest young children.
