Description

  The present invention relates to a self-propelled small traveling toy, and more particularly to a self-propelled small traveling toy provided with two drive sources of motor drive and mainspring drive.

Conventionally, traveling toys that run on their own are generally electrically driven with a motor as a driving force, but even when batteries are exhausted, traveling toys that can be played with the same feeling as a hand-held traveling toy have been proposed. (For example, Patent Document 1). This traveling toy is configured to be able to switch between self-running traveling and hand-running traveling by moving a movable gear by an operation of an external operation unit.
JP-A-6-190151

  The problem to be solved by the present invention is that the above-described traveling toy can be played by switching between self-propelled running and hand-pushing running with a motor as a driving force, but is considered as a driving force for self-propelled traveling. Since the mainspring, which is another driving force, cannot be used for traveling, the battery cannot be used for self-running when the battery is exhausted.

  This invention solves the said problem and makes it a subject to provide the self-propelled small traveling toy which can make two types of self-propelled running properly using two power sources, a motor and a spring.

In order to solve the above problems, a self-propelled small traveling toy according to the present invention is characterized by having the following requirements.
(A) The toy main body is provided with two drive mechanisms, ie, a motor drive mechanism for driving the drive wheels and a mainspring drive mechanism. (B) When a power ON operation is performed to operate the motor drive mechanism, When the motor drive mechanism functions and the mainspring drive unit does not function, and the power OFF operation is performed to operate the mainspring drive mechanism, the mainspring drive mechanism functions and the motor drive unit does not function. The small traveling toy preferably has the following requirements.
(A) The shaft of the drive wheel is pivotally supported on the chassis so as not to move in the left-right direction. (B) The motor drive mechanism and the mainspring drive mechanism are accommodated in a unit case, and the unit case is the chassis. (C) The drive gear linked to the mainspring drive mechanism and the clutch gear linked to the motor drive mechanism are fixed to the shaft, and the unit case is slid to one side. The mainspring drive mechanism functions when the clutch gear and the motor drive mechanism are disengaged, and when the unit case is slid to the other side, the motor drive mechanism functions and the link between the drive gear and the mainspring drive mechanism is disengaged. Then, the mainspring of the mainspring driving mechanism is formed by rotating the driving wheel backward. It can be wound up.

  According to the invention of claim 1, although it is a small traveling toy, it has two drive mechanisms, a motor drive mechanism and a mainspring drive mechanism, and the motor drive mechanism can be operated by turning the power on or off. It is possible to provide an epoch-making self-propelled small traveling toy that can select any one of the mainspring drive mechanisms and prevent the non-selected drive mechanisms from functioning.

  According to the second aspect of the present invention, there is provided a drive gear fixed to the shaft of the drive wheel, wherein a unit case having two drive mechanisms, a motor drive mechanism and a mainspring drive mechanism, is slidably arranged on the chassis. By changing the linkage with the clutch gear, a self-propelled small traveling toy that can be selected without adding a special mechanism can be realized.

  According to the invention of claim 3, the mainspring can be easily wound.

  FIG. 1 shows an example of a self-propelled small traveling toy according to the present invention. The self-propelled small traveling toy 1 has two drives, a motor drive mechanism 3 and a mainspring drive mechanism 4, for driving a drive wheel 2. The mechanism is accommodated in the unit case 5 and the unit case 5 is slid to the left and right to control the ON / OFF of the motor, which will be described later, and the motor drive mechanism 3 is enabled when the motor is ON, and when the motor is OFF This is a small traveling toy having a total length of about 5 cm, in which the mainspring drive mechanism 4 is made effective so that it can run in any case.

  FIG. 2 is an exploded perspective view for explaining the relationship between the chassis 6 and the unit case 5 with the body removed, and an opening 10 for setting the button battery 7 is formed on the floor surface of the chassis 6. A plus electrode 11 arranged in parallel with the opening 10 so as to be in contact with the plus electrode 7a of the button battery 7 is fixed. The notch 12 formed integrally with the rear end of the opening 10 is for exposing a knob 8 (described later) formed on the back side surface of the unit case 5, and by moving the knob 8 left and right. The unit case 5 can be slid left and right.

  Further, the chassis 6 is formed with a holding portion 13 for holding the unit case 5 from the front and rear. The holding portion 13 includes an engagement plate 14 that is erected on the front side of the opening 10 and an engagement edge 15 that is formed on the rear wall surface. A hook 16 is formed on the rear side of the upper end of the engagement plate 14, and the hook 16 of the engagement plate 14 is engaged with an engagement projection 20 formed on the front surface of the unit case 5, and on the rear surface of the unit case 5. The engagement edge 15 is engaged with the formed engagement convex portion 21, and the unit case 5 is held so as to be slidable left and right on the chassis 6.

  A stabilizer 22 is formed on the upper surface of the chassis 6 so that the sliding state can be maintained when the unit case 5 is slid left and right.

  The button battery 7 is accommodated in the unit case 5 from the back side of the chassis 6 through the opening 10. The button battery 7 has a negative electrode 7 b in pressure contact with the negative electrode 23 disposed on the left inner surface of the unit case 5. It is to be housed in a state. Reference numeral 24 denotes a battery lid.

  The front wheel 25 is held so as not to be detached from the bearing 27 by a concave groove 28 formed in the front part of the unit case 5 in a state where the shaft 26 is set in a bearing 27 formed in the front side wall of the chassis 6.

  Next, the motor drive mechanism 3 and the mainspring drive mechanism 4 arranged in the unit case 5 will be described with reference to FIG.

  First, the drive wheel 2 is fixed to both ends of the shaft 30, and the shaft 30 is held by the bearing 31 of the chassis 6, and a protruding portion 2 a formed to protrude from the inner surface of the drive wheel 2 is formed on the outer surface of the chassis 6. The shaft 30 is in contact with the chassis 6 so that the left and right positions are not displaced.

  A drive gear 32 and a fixed ring 33 are fixed to the shaft 30, and a spring 34 and a clutch gear 35 are disposed between the drive gear 32 and the fixed ring 33. The fixing ring 33 is loosely fitted in a recess 35 a formed on the side surface of the clutch gear 35, and the clutch gear 35 is pressed against the fixing ring 33 by a spring 34.

  The motor drive mechanism 3 includes a motor 40, a pinion gear 41 fixed to the output shaft of the motor 40, a first two-stage gear 42 that meshes with the pinion gear 41, and a second two-stage that meshes with the first two-stage gear 42. The gear 43, a third two-stage gear 44 that meshes with the second two-stage gear 43, and a spur gear 45 that meshes with the third two-stage gear 44. A clutch gear 46 is formed on the inner surface of the spur gear 45, and the clutch gear 35 is urged by the spring 34 to mesh with the clutch gear 46. The rotation of the motor is caused by the pinion gear 41, It is transmitted to the spur gear 45 via the first two-stage gear 42, the second two-stage gear 43, and the third two-stage gear 44, and to the clutch gear 35 via the clutch gear 46 integrated with the spur gear 45. The transmitted drive gear rotates 32 times, and the drive wheel 2 rotates.

  It should be noted that the spring 34 prevents the motor 40 from being loaded by causing the clutch gear 35 and the clutch gear 46 to be disengaged even if the drive wheel 2 cannot rotate and the drive gear 32 does not rotate. Is for.

  The second two-stage gear 43 and the spur gear 45 are free on the shaft 30 so that when the unit case 5 is slid, the second two-stage gear 43 and the spur gear 45 are slid and engaged with the other two-stage gears 42 and 44. It has become.

  The mainspring drive mechanism 4 includes a mainspring 50, a spur gear 52 that is engaged with the spur gear 52, a spur gear 52 that is engaged with the spur gear 52, and a planetary gear 53 that meshes with the planetary gear 53. The two-stage gear 54 is configured to always mesh with the drive gear 32 described above. When the drive wheel 2 is rotated backward, the drive gear 32, the two-stage gear 54, and the planetary gear 53 are provided. The spur gear 52 is rotated via the spring 50 so that the mainspring 50 can be wound up.

  Next, the traveling mode of the self-propelled small traveling toy configured as described above will be described.

  First, the case where self-running running is performed using the motor 40 as a driving force will be described. As shown in the bottom view of FIG. 4A, when the knob 8 exposed in the notch 12 is moved to the left (arrow a direction), the unit case 5 slides to the left with respect to the chassis 6 in the drawing. . In this state, as shown in FIG. 4B, the unit case 5 slides to the right (in the direction of the arrow b), but the lateral position of the drive wheel 2 and the shaft 30 relative to the chassis 6 does not change, so the clutch gear 46 meshes with the clutch gear 35.

  On the other hand, the negative electrode 7b of the button battery 7 is moved to the right together with the unit case 6 while being pressed against the negative electrode 23. Therefore, the positive electrode 7a comes into contact with the positive electrode 11 fixed on the floor surface of the chassis 6, and the motor A voltage is applied to 40 and the motor 40 rotates. When the motor 40 rotates, it is transmitted to the spur gear 45 through the pinion gear 41, the first two-stage gear 42, the second two-stage gear 43, and the third two-stage gear 44, and the clutch that is integrated with the spur gear 45 is provided. The drive gear 2 is rotated 32 times by being transmitted to the clutch gear 35 through the gear 46 and the drive wheel 2 is rotated, so that the self-propelled small traveling toy 1 travels by itself using a motor as a driving force.

  At this time, as shown in FIG. 6A, the drive gear 32 rotates counterclockwise, the two-stage gear 54 rotates clockwise, and the planetary gear 53 rotates counterclockwise. The gear 53 tries to rotate the spur gear 52, but since the mainspring is linked to the spur gear 52, the planetary gear 53 escapes along the long hole 55 so as to run up the spur gear 32. Even if the drive gear 32 rotates and the driving gear 32 rotates, the mainspring 50 is not wound up.

  Next, a case where the mainspring 50 is used as a driving force for self-traveling will be described. As shown in the bottom view of FIG. 5A, when the knob 8 exposed in the notch 12 is moved to the left (arrow c direction), the unit case 5 slides to the right with respect to the chassis 6 in the drawing. . In this state, as shown in FIG. 5B, the unit case 5 slides to the left (in the direction of the arrow d), but the lateral position of the drive wheel 2 and the shaft 30 with respect to the chassis 6 does not change, so that the fixed ring The clutch gear 35 is prevented from moving by being blocked by 33, so that the clutch gear 35 and the clutch gear 46 are disengaged.

  On the other hand, since the button battery 7 moves to the left together with the unit case 6, the contact between the plus electrode 7a and the plus electrode 11 fixed to the floor surface of the chassis 6 is released, and the voltage application to the motor 40 is released. Therefore, the rotation of the motor 40 stops.

  In this state, as shown in FIG. 7A, when the drive wheel 2 is moved backward while being in contact with the floor and the drive wheel 2 is reversely rotated, a so-called pullback operation is performed as shown in FIG. 6B. The drive gear 32 rotates clockwise, the two-stage gear 54 rotates counterclockwise, and the planetary gear 53 rotates clockwise to rotate the spur gear 52 counterclockwise. At this time, since the planetary gear 53 rotates so as to push up the spur gear 52, it moves to the lower end side of the planetary gear 53 long hole 55, and the meshing with the spur gear 52 is not released, so that the mainspring 50 is reliably wound up. Can do.

  After fully retracting the self-propelled small traveling toy and winding up the mainspring 50, as shown in FIG. 7B, when the hand is released from the self-propelled small traveling toy 1, as shown in FIG. 6C. In addition, the spur gear 52 is rotated clockwise by the rewinding force of the mainspring 50, and the drive gear 32 is rotated counterclockwise via the planetary gear 53 and the two-stage gear 54. The traveling small traveling toy 1 can be self-propelled by using the mainspring 50 as a driving force.

  As described above, when the motor 40 is turned on by sliding the unit case arranged on the chassis to the left or right, the motor 40 can be driven as a driving force, and the motor is turned off. When this happens, the mainspring can be used as a driving force for self-propelled running. In addition, when the motor drive mechanism is enabled, the mainspring drive mechanism is not affected, and when the mainspring drive mechanism is enabled, the motor drive mechanism is not affected. It is possible to freely select which drive mechanism to use to drive with simple operation, so that when one of the drive mechanisms is operating, the other operating mechanism is not affected An innovative self-propelled traveling toy can be realized.
