Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a running toy whose running speed can be changed by operating an operating member provided in a portion that forms an external shape.

Various toys have been known in the past whose external shape changes from robots to airplanes, submarines, etc., but these are mobile toys that can move on wheels, change shape, and change the running speed according to the shape change. There are not many toys that are constructed so that they can be changed. This is because if an attempt was made to change the traveling speed in accordance with the change in shape, the structure of the transmission mechanism for changing the traveling speed would be large and complicated, so it would be difficult to incorporate it into a small space or to change the speed. This is because there are problems such as difficulty in locating operating knobs and the like in desired positions, and it is therefore difficult to plan toys that are inexpensive and can be mass-produced.

The present invention has been made in view of the above-mentioned conventional circumstances, and by operating an operating member provided in a portion that forms an external shape, a displacement member is displaced in a predetermined direction, and a driving gear and a driven gear that mesh with each other are moved. To provide a traveling toy configured so that the tooth ratio of a gear can be changed, thereby easily changing the traveling speed, and in which a displacement transmission mechanism of a displacement member can be compactly incorporated.

In order to achieve this object, the present invention includes a power unit that transmits running power to a pair of drive gears having different diameters via a reduction gear mechanism, and a power unit that transmits running power to a pair of drive gears having different diameters, and a drive gear that selectively transmits running power to a predetermined one of the pair of drive gears. A pair of driven gears having different diameters that are capable of engaging and disengaging and are integrally displaceable in the axial direction on an axle that supports a wheel, and a pair of arms that abut at least one side surface of the pair of driven gears. has
a displacement member that can be displaced substantially parallel to the axis of the axle; and a displacement member provided in a portion that forms the external shape;
The gist of the present invention is to include an operation member that displaces the displacement member in a predetermined direction by an external operation and switches the meshing state of the driven gear and the drive gear.

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are perspective views showing the state before and after deformation of an embodiment of the traveling toy of the present invention, respectively, and FIG. 3 is an exploded perspective view of the traveling toy before deformation.

In Fig. 1, the running toy 1 has a three-wheeled robot shape, and when viewed from the front, left and right wheels 2l, 2r.
A torso 4 has wheels 2a (shown in FIG. 2) on the back, rotatable arms 3l and 3r at positions corresponding to both shoulders, and a neck that twists to the left and right on the top of the torso 4. The head 5 is rotatably provided so as to be rotated, and is composed of a head 5 and the like having wheels 2b on the back side. The root portions of the arms 3l, 3r are pivotally supported on the upper parts of the wing bodies 6l, 6r, and eccentric holes 7 formed in parts of the wing bodies 6l, 6r are installed in the sides of the wheels 2l, 2r. Since the pin 8 is engaged, the wing bodies 6l, 6r swing and displace with the rotation of the wheels 2l, 2r during running, and the tips of the arms 3l, 3r, which are swung horizontally forward, reciprocate up and down. .

Here, the wing bodies 6l, 6r can be opened and closed to the left and right, and first, the arm parts 3l, 3 are swung forward.
By swinging down r to the side of body 4 and expanding wing bodies 6l and 6r to the left and right in this state, traveling toy 1 approaches the shape of a jet aircraft from a robot shape. Therefore, when the head 5 is twisted 180 degrees with respect to the body 4 to change its direction, the wheel 2b provided on the back of the head 5 is supported at three points along with the wheels 2l and 2r, so-called three-wheeled. The supporting jet machine shape is completed. In this case, as shown in Figure 2,
Although the arm parts 3l and 3r are in opposite directions, the arm part 3
The bases of the wings 6l and 3r are shaped like warheads, giving the impression that a missile is mounted on the top of the wings 6l and 6r. In addition, the movable protector 5a installed on the front side of the head 5 has now been changed to a jet aircraft's cockpit hood, and a pair of small wing bodies 4a protruding from the back side of the fuselage 4 are actually used as vertical tails. enhance the sense of

As described above, the traveling toy 1 is configured so that the shape can be changed from a robot shape to a jet machine shape or vice versa. It is also unique in that it allows you to change the running speed. In this embodiment, the head 5 is used as an operating member for changing the traveling speed.

In FIG. 3, the power unit 11, which can be said to be the heart of the traveling toy 1, includes a reduction gear mechanism 12 and a flywheel 1.
3 is integrated into one block, and a small diameter gear 121 coaxially provided at the bottom of the flywheel 13 incorporated in the block frame 11a is connected to a large diameter gear in the same reduction gear mechanism 12. gear 1
A small diameter gear 123, which is coaxially integral with the large diameter gear 122, meshes with a crown gear 124 pivotally supported on the lower surface of the block frame 11a. This crown gear 1
A pair of large and small drive gears 14l and 14r having different diameters are integrally fixed to the shaft 24 with a predetermined distance between them.

On the other hand, an axle 20 that connects and fixes the wheels 2l and 2r
, a pair of large and small driven gears 15 having different diameters correspond to the pair of drive gears 14l and 14r.
r, 15l are provided so as to be integrally displaceable in the axial direction, and engagement protrusions 16l, 16r protruding from the side surfaces of each driven gear 15l, 15r engage one wheel 2l or 2.
By engaging the bearings 17l and 17r of r from the inside, power is transmitted to the wheel 2l or 2r. Therefore, the driven gears 15l, 15
When r is displaced toward the wheel 2l and the engagement protrusion 16l engages with the bearing 17l, the small-diameter driven gear 15
1 meshes with the large-diameter drive gear 14l, thereby selecting the low-speed travel mode. Conversely, when the driven gears 15l and 15r are displaced toward the wheel 2r and the engagement protrusion 16r engages with the bearing 17r, the large diameter driven gear 15r moves to the small diameter driving gear 1.
4r, thereby selecting the high-speed running mode.

By the way, the block frame 11a of the power section 11
A pin 11b for pivotally supporting the swing plate 18 as a displacement member is installed on the back surface of the
A swing plate 18 pivotally supported on the head 5 as an operating member
It functions to transmit and convert the rotation of the driven gears 15l and 15r into displacements of the driven gears 15l and 15r. That is, the eccentric pin 1 on the lower surface of the cam plate 19 fixed to the lower surface of the head 5 is inserted into the U-shaped groove 18a formed in the upper bent portion of the swing plate 18.
9a are engaged with each other, and a pair of arm portions 18b branched from the lower end of the swing plate 18 abut and lock on both sides of the large-diameter driven gear 15r.

Therefore, when the traveling toy 1 has a robot shape as shown in FIG. 18 is inclined diagonally upward to the right. As a result, the driven gear 15r is
The driven gear 15 is pushed by the arm portion 18b of the swing plate 18.
1 and is displaced toward the wheel 21 side, and the low-speed running mode is selected as described above.

On the other hand, in order to change the shape of the traveling toy 1 from a robot shape to a jet machine shape, when the head 5 is twisted approximately 180 degrees to change its direction, the cam plate 19
The eccentric pin 19a moves to a position eccentric to the left of the central axis when viewed from the front. As a result, the rocking plate 1
8 is tilted diagonally upward to the left, and the driven gear 15
r is pushed by the arm portion 18b of the rocking plate 18 and is displaced toward the wheel 2r together with the driven gear 15l. Therefore, the driving mode becomes a high speed driving mode. In addition,
A pair of protrusions 19b formed on the outer periphery of the cam plate 19
However, the rotation of the head 5 is clicked every 180 degrees by engaging between a pair of elastic struts 11c installed in the upper part of the block frame 11a.

In this way, the traveling toy 1 having the above configuration can switch the traveling mode between two modes, low speed and high speed, in accordance with the twisting operation of the head 5 when changing the shape, and each traveling mode can change the shape after the shape change. Since the vehicle has a speed suitable for the vehicle, changes in shape and changes in running speed can be integrated to satisfy children's intellectual curiosity.

Further, the mechanism for determining the running mode of the running toy 1 includes the head 5, the cam plate 19, the rocking plate 18, the driven gears 15l, 15r, the reduction gear mechanism 12, etc., and these parts will be described later. As shown in FIG.
The swing plate 18 that transmits the signal to the block frame 11a
Since it is assembled in such a way that it fits closely to the back of the camera, the overall structure can be made extremely compact without leaving any wasted space. In addition, since the power unit 11 consisting of the reduction gear mechanism 12 and the flywheel 13 is made into a block, the assembly work is easy.
It is possible to reliably eliminate assembly defects such as those where 15r is not properly engaged.

In addition, here is how to assemble traveling toy 1.
Explain briefly. First, the power unit 11 with the rocking plate 18 attached to the back is assembled into the back cover 4b of the body 4, and then both bearings 17l, 17r of the axle 20 are assembled.
is held by the bearing holding portion 21 of the back cover 4b. At this time, the drive gear 14l on the power unit 11 side,
14r and the driven gears 15l and 15r on the axle 20 side are in a state where selective meshing is possible.

Next, the head 5 is assembled so that the eccentric pin 19a of the cam plate 19 engages with the groove 18a of the rocking plate 18, and then the front cover 4c of the body 4 is fitted to the rear cover 4b. Then, the two divided mufflers 5b and 5c are wrapped around the neck of the head 5 and fixed with screws, thereby fixing the matched state of the covers 4c and 4d. The remaining left and right arm parts 3l,
3r and the wheel 2a are supported by respective support shafts 23l, 23.
After locking r and 22a to the back cover 4b,
It is assembled by applying the presser cover 24 with the small wing body 4a from above and fixing the presser cover 24 to the rear cover 4b with screws.

In this way, the traveling toy 1 is assembled with the body 4
This is done in the inside of the toy, then the head 5, and then the arms 3l and 3r, but the body 4 and head 5 alone have the basic functions of a running toy. Therefore, by changing the shape of the torso 4 and the shapes of the attached arms 3l, 3r, etc., there is plenty of room to change the model from jet aircraft to tanks, submarines, etc., and various modifications are possible. It goes without saying that it is possible.

Further, in the above embodiment, the head 5 is used as the operating member.
Although we have taken an example using the head 5, it goes without saying that parts other than the head 5 may be used as the operating member.

As explained above, according to the traveling toy of the present invention, the displacement member disposed around the power section is displaced by the operation of the operation member shown in the external shape,
As long as the meshing state of the driving gear and the driven gear can be easily switched, and the guided displacement of the driven gear by the displacement member is reliable, good meshing switching is possible. High and low 2
This provides effects such as being able to switch speeds and providing small, inexpensive toys that are highly effective in mass production.
