Detailed Description

An embodiment of the present invention will be described below with reference to the accompanying drawings.

The toy boat 21 according to the embodiment described below is an electric toy including a motor as a driving source.

First, an electric toy transport trailer will be described.

Figure 1 is a toy boat loaded onto an electric toy transport trailer coupled to a toy vehicle with a coupling. Fig. 2 is a side view of the electric toy transport trailer shown in fig. 1. Fig. 3 is a rear view of the electric toy transport trailer shown in fig. 1. Figure 4 is a perspective view of the toy boat unloaded upwardly from the electric toy transport trailer. Fig. 5 is a perspective view of the rechargeable main power source container with the container lid open for the electric toy transport trailer. FIG. 6 is a partial perspective view of the toy boat with the cover removed to reveal the power source. In fig. 3, the electric toy transport trailer is illustrated in a modified double-dashed line, so that the toy boat is highlighted in the figure.

The figure illustrates a power toy transport trailer 11 comprising a power toy transport trailer body 12 and a coupler 18 disposed on the power toy transport trailer body 12, thereby coupling the power toy transport trailer body 12 to the coupler C of the toy vehicle M.

The tires 13 are attached to the electric toy transport trailer body 12 such that the electric toy transport trailer body 12 is pulled and moved by the toy vehicle M. The container box 14 is provided at the rear of the coupling 18, i.e., the upper portion of the tip of the electric toy transport trailer body 12, so that the container box 14 does not interfere with the toy boat 21 loaded on the electric toy transport trailer body 12. Also, a rechargeable main power source container 15 with a cover 15a is provided at the center of the electric toy transportation trailer body 12, and the container 15 is configured to contain a rechargeable main power source 17a constituting a charger 17.

On the upper side of the cover 15a of the rechargeable main power source container 15, a plurality of (e.g., 2) protrusions 16 having a predetermined height are provided to support the toy boat 21 from below. The charger 17 includes a power source (e.g., a battery), the rechargeable main power source 17a is stored in the rechargeable main power source container 15, the flexible cable 17b is connected to the rechargeable main power source 17a and extends into the container box 14 through the electric toy transport trailer body 12, and the charging connector 17c is connected to the flexible cable 17b and stored in the container box 14. The rechargeable main power source 17a is stored in the rechargeable main power source container 15 so that it is placed under the upper edge of the tire 13.

The inside of the hull 22 of the toy boat 21 is a container 22 a. The container 22a stores various components, such as a power source 23 detachable from the container 22 a. The opening of the container 22a is closed water-tightly with a cover 22b, and a groove 22e is provided at the bottom of the hull 22 to penetrate the hull 22 in the longitudinal direction.

In order to load the toy boat 21 onto the electric toy transport trailer 11 having the above-described structure, the recess 22c provided at the lower portion of the hull 22 is aligned with the protrusion 16 of the cover 15a in such a manner that the protrusion 16 enters the recess 22c, as shown in fig. 4, thereby supporting the toy boat 21.

To transport the toy boat 21 with the electric toy transport trailer 11, the toy boat 21 is first loaded onto the electric toy transport trailer 11, as described above, and then the coupler 18 is coupled to the toy vehicle. Thus, the toy boat 21 can be transported on the electric toy transport trailer 11 by moving the toy vehicle M.

To charge the power source 23 of the toy boat 21, first, as shown in fig. 6, the cover 22b is removed to detach the power source 23 from the hull 22. Then, as shown in fig. 5, the container box 14 is opened to detach the charging connector 17c from the container box 14, and the charging connector 17c is connected to the power source 23. Subsequently, a switch 12a mounted on the upper surface of the electric toy transport trailer body 12 is pressed to illuminate a light emitting diode 12b, which indicates that the power source 23 is being charged and that the power source 23 is being charged. After the charging is completed, the charging connector 17c is stored in the container box 14, and then the container box 14 is closed. In front of the rechargeable main power source container 15, a control board configured to drive the light emitting diode 12b and control the charging of the power source 23 is provided.

As described above, since the charger 17 configured to charge the power source 23 of the toy boat 21 is provided on the electric toy transport trailer body 12, the power source 23 of the toy boat 21 can be charged with the electric toy transport trailer 11. Further, since the charger 17 includes the chargeable main power source 17a and the charging connector 17c connected to the chargeable main power source 17a through the flexible cable 17b, while since the chargeable main power source 17a is accommodated in the electric toy transport trailer body 12, the chargeable main power source 17a can be provided on the electric toy transport trailer body 12 without changing the appearance of the electric toy transport trailer body 12.

Further, since the rechargeable main power source 17a is accommodated in the electric toy transport trailer body 12 in such a manner that the rechargeable main power source 17a is placed at a position lower than the upper edge of the tire 13, the center of gravity is lowered and stability is increased. Thus, the toy boat 21 is prevented from being turned over. Since the charging connector 17c is stored in the container box 14 provided on the electric toy transport trailer body 12 so as to be openable and closable, the charging connector 17c can be stored in the container box 14 when the container box is not used. Thus, the toy boat 21 has a simple shape.

Since the recess 22c is provided at the bottom of the toy boat 21 and since the plurality of protrusions 16 configured to support the toy boat 21 by entering the recess 22c of the toy boat 21 are provided on the cover 15a of the rechargeable main power source container 15, the container 15 is configured to store the rechargeable main power source 17a of the electric toy transport trailer body 12, the toy boat 21 can be loaded on the electric toy transport trailer 11 and transported in a stable state.

Next, the toy boat 21 is described.

Fig. 10 is a rear view of the servo mechanism and the propeller in a mounted state. Fig. 11 is a plan view illustrating the overall structure of the servo mechanism. Fig. 12 is a longitudinal sectional view of the servo mechanism. Fig. 13 is an exploded view illustrating the structure of the shock absorbing mechanism and the propeller angle adjusting mechanism. Fig. 14 and 15 are schematic views illustrating the operation and working of the impact absorbing mechanism. Fig. 16 is a schematic view illustrating the operation of the propeller angle adjustment mechanism.

As shown in the drawings, the toy boat 21 includes: a hull 22; a rechargeable power source 23 that is detachable from the hull 22 and can supply power to various components; an antenna 24 mounted on the hull 22 and capable of receiving control signals from a controller not shown; a control device (not shown) installed inside the hull 22 and capable of controlling various components based on signals from the antenna 24; a motor 26 mounted on the inside of the hull 22 and controlled by a control device; a drive shaft 27 having a first end connected to the rotating shaft of the motor 26 and a second end extending outside the hull 22; a propeller 29 connected to a second end of the drive shaft 27 located outside the hull 22 with a polygonal universal coupling 28 having a polygonal pyramid; a propeller bracket 30 configured to rotatably support the propeller 29, which functions as a rudder; a servo mechanism 31 configured to rotate the propeller bracket 30 toward a horizontal position; an impact absorbing mechanism 32 configured to mount the servo mechanism 31 to the outside of the hull 22 so that the servo mechanism 31 can be turned to a horizontal position and transmit power generated at the servo mechanism 31 to the propeller bracket 30; and a propeller angle and depth adjustment mechanism 38 (hereinafter simply referred to as "propeller adjustment mechanism 38") configured to adjust the angle of the propeller and the depth of the propeller. Also, a drive shaft 31b, which is a flexible tube, is provided to cover the outer circumference of a flexible cable for connecting the control device and the servo 31 and to prevent water from entering the servo 31.

Inside the hull 22 is a container 22 a. The container 22a stores various components. The opening of the container 22a is closed water-tightly with a lid 22 b.

At the bottom of the hull 22, as shown in fig. 3, a groove 22c is provided which penetrates the hull 22 in the longitudinal direction.

On the left and right sides of the propeller support 30, a plurality of (e.g., 2) protrusions 30a are provided on a circle centered on the drive shaft 27 and the connecting part 28a of the polygon universal coupling 28 in such a manner that, for example, the protrusions 30a in pairs are at the same position with respect to the circle.

Components such as a motor and a gear are accommodated in a housing 31a of the servo mechanism in a water-tight manner, and signal lines from the hull 22 are also sealed in a barrel-shaped sealing pipe, as shown in fig. 13, and a final stage transmission shaft 31b has a D-cut lower end. The D-cut portion is connected to a tip end portion 31c of the shaft, the portion 31c having a projection 31cb projecting from an outer periphery of the cylinder 31ca in the direction of the shaft and being rotatable together with the transmission shaft 31 b.

As shown in fig. 13, the impact absorbing mechanism 32 includes: a support shaft 35 provided with a fixing screw 33 on an upper rear edge of a support member 34 mounted on a tail portion of the hull 22, the support shaft having one projection 35b projecting from an outer periphery of the shaft 35a in the shaft direction; the shaft end portion 31c of the servo mechanism 31; an elastic C-ring member 36 holding the protrusions 31cb, 35b with a gap and surrounding the cylinder 31ca and the shaft 35 a; and a connecting screw 37 configured to fix the shaft end portion 31C, the support shaft 35, and the C-ring member 36 to the support member 34.

As shown in fig. 13, the propeller adjustment mechanism 38 includes: a first fixed bracket 39 whose upper edge is connected to the housing 31a of the servo mechanism 31; a second fixing bracket 40 mounted to the first fixing bracket 39 with a fixing screw 41, and the propeller bracket 30 includes a projection 30a interposed and fixed between the first and second arc-shaped grooves 39a and 40 a. The first fixing bracket 39 includes a first arc-shaped groove 39a centrally surrounding the connecting part 28 a. The second fixing bracket 40 includes a second arc-shaped groove 40a centrally surrounding the coupling part 28a and opposite to the first arc-shaped groove 39 a. The propeller support 30 is movable in and along the first and second arcuate slots 39a and 40a, wherein the movement is centered with the connecting part 28 a.

The operation will be described below.

When a control signal from the controller is received at the antenna 24, the received control signal is provided to a control device (not shown in the figure). The control device that receives the control signal in the above-described manner controls the various devices based on the control signal.

The control of the motor will be described below.

When the control device operates the motor 26, the toy boat 21 moves, and when the control device stops the motor 26, the toy boat 21 stops moving. The speed of the toy boat 21 may be increased or decreased by increasing or decreasing the number of revolutions with the control device. According to this embodiment, by storing the motor 26 whose weight is large in the hull 22, the center of gravity of the hull 22 is lowered, and therefore, stable movement is achieved.

Next, the steering direction will be described.

To guide the toy boat 21 to move linearly, a support shaft 35, a C-shaped ring member 36, and a shaft end portion 31C included in the servo mechanism 31 and the impact absorbing mechanism 32 are configured as shown in fig. 14.

In this configuration, if the servo 31 is moved by a predetermined amount so as to turn the toy boat 21 to the left, the servo 31 is moved to the left (clockwise) with respect to the impact absorbing mechanism 32 as shown in fig. 15 because the shaft end portion 31C is fixed to the support shaft 35 by the C-shaped ring member 36.

In this way, when the servo mechanism 31 is rotated, the propeller bracket 30 is also turned to the left (clockwise) with respect to the impact absorbing mechanism 32 because the propeller bracket 30 is fixed to the housing 31a with the first and second fixing brackets 39 and 40. This allows steering.

Despite such movement of the toy 21, if, for example, the right side of the propeller bracket 30 contacts an obstacle, the propeller bracket 30 turns further to the left (clockwise). At this time, the C-ring member 36 elastically extends and absorbs the impact. After the absorption of the impact is completed, the C-ring 36 is elastically restored to its original state.

The adjustment of the angle and depth of the propeller will be described below.

First, the fixing screw 41 is loosened, and as shown in fig. 16, the propeller bracket 30 is pivoted about the connecting part 28a along the vertical plane while guiding the projection 30a along the first and second arc-shaped grooves 39a and 40 a. Thus, the propeller 29 can be set to a predetermined angle, and then the fixing screw 41 is tightened while the protrusion 30a is interposed and fixed between the first and second brackets 39 and 40.

As described above, since the toy boat 21 according to the present invention may further include the shock absorbing mechanism 32 configured to connect the hull 22 with the servo mechanism 31, wherein the shock absorbing mechanism 32 includes: a support shaft 35 having a projection 35b extending from the outer periphery of the shaft part 35a in the direction of the shaft, wherein the support shaft 35 is mounted on the hull 22; a shaft end portion 31c having a projection 31cb extending from the outer periphery of the cylinder 31ca in the direction of the shaft, wherein the shaft end portion 31c is connected to a transmission shaft 31b of the servo 31; and an elastic C-ring member 36 configured to place and hold the first and second protrusions 35b and 35cb with a gap and to surround the shaft part 35a and the cylinder 31ca, so that even if the propeller bracket 30 contacts an obstacle and receives an impact, the C-ring member 36 is extended or contracted to absorb the impact. Thus, the servo mechanism 31 is prevented from being damaged.

Since the propeller bracket 30 is fixed to the housing 31a of the servo mechanism 31, the propeller bracket 30 can be directly turned to the horizontal position by the servo mechanism 31. Thus, a link configured to transmit power generated at the servo mechanism 31 to the propeller support 30 to steer and rotate the propeller support 30 toward the horizontal position is not required. Therefore, the steering direction can be easily adjusted.

The motor 26 is mounted to the inside of the hull 22, the propeller 29 is connected to the drive shaft 27 through a polygon universal joint 28 outside the hull 22, the drive shaft 27 is driven by the motor 26, and the propeller adjustment mechanism 38 is configured to adjust the angle of the propeller 29 by pivoting the propeller 29 about a connecting part 28a, the connecting part 28a connecting the polygon universal joint 28 and the drive shaft 27. Thus, the propeller support 30 can be turned while being centered around the connecting piece 28a so as to finely and easily adjust the angle of the propeller 29 according to the state and/or size of the waves and the type of propeller. Thus, the direction of the toy boat 21 can be steered in directions suitable for various states.

The servo mechanism 31 is installed outside the hull 22 so that the propeller support 30 can be rotated to a horizontal position, and, as shown in fig. 13, the propeller adjustment mechanism 38 includes a first fixing bracket 39 whose upper edge is mounted to the housing 31a of the servo mechanism 31 and a second fixing bracket 40 mounted to the first fixing bracket 39 with a fixing screw 41, and the propeller support 30 includes a projection 30a interposed and fixed between the first and second arc-shaped grooves 39a and 40 a. Further, the first stationary bracket 39 includes a first arcuate slot 39a centered about the connecting feature 28a, and the second stationary bracket 40 includes a second arcuate slot 40a centered about the connecting feature 28a and opposite the first arcuate slot 39a, and the propeller bracket 30 is movable in and along the first and second arcuate slots 39a and 40a, wherein the movement is centered about the connecting feature 28 a. Thus, the propeller support 30 can be turned to the horizontal position by the servo 31 by means of the first and second fixing supports 39 and 40. Thus, a link configured to transmit the power generated at the servo mechanism 31 to the propeller support 30 for manipulating and turning the propeller support 30 to the horizontal position is not required. Therefore, the steering direction can be easily adjusted.

Since the plurality of (e.g., 2) protrusions 20a are provided, the propeller bracket 30 can be firmly fixed by the first and second fixing brackets 39 and 40. Since the universal joint is the polygonal universal joint 28, the toy boat 21 having the above-described advantages can be provided at low cost.

The toy boat 21 transported by the electric toy transport trailer 11 according to the above-described embodiment is not limited and may be any electric toy such as a toy car or a toy airplane.

In the above embodiment, the drive source directly rotates the propeller bracket 30. However, the driving source may be installed inside the hull 22, while the servo mechanism may be installed outside the hull 22. In this way, the distance between the servo mechanism 31 and the propeller support 30 is reduced, and the propeller support 30 can be directly rotated to a horizontal position by the servo mechanism 31. Therefore, there is no need for a link configured to transmit power generated at the servo mechanism 31 to the propeller support 30 for steering and to turn the propeller support 30 to a horizontal position.

In the above embodiment, the shaft end portion 31c is connected to the transmission shaft 31b of the servo mechanism 31. However, the edge of the transmission shaft 31b may be formed in the same manner as the shaft end portion 31 c. In this case, in order to obtain the same advantages as those of the above-described embodiment, the propeller adjustment mechanism may include a first fixing bracket 39, a second bracket 40, and the propeller bracket 30, wherein the upper edge of the first fixing bracket 39 is mounted on the hull 22, so that the first fixing bracket 39 can be turned to a horizontal position, the first bracket 39 includes a first arcuate slot 39a centered about the connecting feature 28a, the second bracket 40 includes a second arcuate slot 40a, the arcuate slot 40a is opposite the first arcuate slot 39a and is centered about the coupling feature 28a, the second bracket 40 is connected to the first bracket 39, the propeller bracket 30 is centered about the connecting element 28a and is arranged such that the propeller bracket 30 is movable in and along the first and second arcuate slots 39a and 40a, while the propeller bracket 30 includes a protrusion 30a interposed and fixed between the first and second fixing brackets 39 and 40.
