Description

  The present invention relates to a jumping body, and more particularly to a structure improvement of a jumping body that can be applied to a jumping toy or the like.

  As this type of jumping body, for example, those shown in the patent literature are known. In this toy, a toothless rotating cam (gear) is meshed with the rack, and the outer shell is pushed down against the leg against the extension force of the spring by rotating the gear. Then, at the time of jumping, the state of engagement between the stopper and the edge of the linkage portion is canceled, and the body shell is pulled up by the extension force of the spring so as to jump.

Utility model registration No. 3066294

  However, in the above-described conventional jumping body, since the gear and the rack are engaged to push down the outer shell against the spring stretching force, it is difficult to operate quickly, and the jumping body to which the impact force acts is used. It is also difficult to reliably maintain the meshing state of the gear and the rack. In addition to the meshing of the gear and the rack, there is a problem that the structure is complicated because it is necessary to provide a mechanism for canceling the engagement state between the stopper and the end of the linkage portion when jumping.

  Therefore, the present invention solves such problems, and an object of the present invention is to provide a jumping body that can operate at high speed and surely and has a simple structure.

To achieve the above object, according to the first aspect of the present invention, the first half (1) and the second half disposed so as to be movable relative to the first half (1) in the approaching direction and the separating direction. Provided in one of the body (2), the urging member (4) for urging the halves (1, 2) away from each other, and the first half (1) or the second half (2) The cam body (3) formed with the guide portion (32), the drive member (12) for rotationally driving the cam body (3), and the first half (1) to the second half (2) And a part (51) thereof is guided by the guide portion (32) of the cam body (3), and the biasing force of the biasing member (4) is caused by the rotation of the cam body (3). The first half (1) and the second half (2) are moved in the approaching direction against the first half (1) and the second half (2) by the biasing force of the biasing member (4). 2) Move away Is thereby provided with an operating member (5), a guide portion the cam member of the cam body (3) (3) which is formed in a long hole-shaped guide hole (32), the tip of the operation member (5) (51) is located in the guide hole (32), and a notch for locking (323, which bends in the direction intersecting the extending direction of the guide hole (32) at the end or intermediate portion of the guide hole (32). 324) is formed, and the operating member (5) is locked to the notches (323, 324) during the rotation of the cam body (3) in one direction, so that the urging force of the urging member (4) Accordingly, the first half (1) and the second half (2) are moved in the approaching direction, the cam body (3) is further rotated in one direction, or the cam body (3) is moved in the other direction. The first half (1) and the second half are released by the urging force of the urging member (4) by canceling the locking state with the notches (323, 324) by rotation. 2) those which movement the separation direction.

In the first aspect of the present invention, after the cam body rotates, the first half and the second half are moved in the approaching direction against the biasing force of the biasing member via the operation member, and then the biasing member is attached. When the first half and the second half are moved away from each other by the force, the jumping body jumps up due to the inertial force at this time. In the first aspect of the present invention, since the operation member guided by the guide member performs the jump by the biasing force accumulation and the subsequent release of the biasing member, it is compared with the conventional structure using the meshing of the gear and the rack. Thus, quick and reliable operation is possible and the structure is simple. In this case, the rotation of the cam body may always be normally rotated in the whole process of urging force accumulation and urging force release thereafter, or the urging force of the urging member is accumulated by normal rotation, The biasing force of the biasing member may be released by reverse rotation. In the first invention, the operation member can be guided with a simple structure. In addition, since the operation member is locked in the notch, the process of accumulating the urging force in the urging member and the jumping process by releasing the urging force thereafter are clearly separated to realize stable jumping operation at all times. can do.

In the second invention, at least a part of the outer shape of the cam body (3) is eccentric from the center of rotation, and one end of the other operation member (17) that realizes a function other than jumping is the outer periphery of the cam body (3). Abut.

In the second aspect of the invention, functions other than jumping are exhibited with the rotation of the cam body via the other operation members. Here, the “function” is, for example, restoration assistance when a jumping body falls or movement when a hand is provided.

In the third aspect of the present invention, posture adjustment mechanisms (61, 62) for adjusting the tilt posture of the jumping body before jumping are provided.

In the third aspect of the invention, the jumping body can be jumped in the desired direction by adjusting the inclined posture of the jumping body in the desired direction.

In the fourth aspect of the invention, a ring-shaped restoration auxiliary body (15) that assists in restoring the jumping body at the time of falling is provided around the half (1) on the side that is not in contact with the ground.

In the fourth invention, the overturned jumping body is supported in an inclined posture by the outer periphery of the restoration assisting body and the half on the grounding side. Therefore, if the cam body is rotated so that the half body that is not grounded approaches the half body that is grounded, the movement of the center of gravity of the half body that is not grounded at this time is integrated with this. The jumping body is returned to the standing posture by the pushing-up force of the moving restoration assisting body.

  The reference numerals in the parentheses indicate the correspondence with specific means described in the embodiments described later.

(First embodiment)
1 and 2 show an example in which the jumping body of the present invention is applied to a jumping toy, FIG. 1 is a side view thereof, and FIG. 2 is a front view thereof. The jumping body includes an upper half 1 as a first half located above and a lower half 2 as a second half located below. In addition, if the weight of the upper half 1 is made larger than the weight of the lower half 2, an effective jumping operation can be realized.

The upper half 1 is provided with a substantially circular base frame 11. A motor 12 as a driving member is installed on the base frame 11, and a communication circuit 13 is provided. A plate-like cam body 3 is attached to a motor rotating shaft 121 that protrudes horizontally. The cam body 3 is substantially circular, and a part of the outer periphery is a protruding portion 31 protruding outward in a triangular shape. The cam body 3 has a circular center fixed to the motor rotating shaft 121, and a long hole-shaped guide hole 32 as a guide portion is formed on the plate surface thereof.

  The guide hole 32 is formed in a straight line so as to cross half of the circular plate surface, and bends in the same direction at one end 321 and an intermediate position at a substantially right angle intersecting the extending direction of the guide hole 32. Locking notches 323 and 324 are formed. The notch 324 is continued by the other end 322 of the guide hole 32 and the hypotenuse 325.

  A dome-shaped cover body 14 is covered on the base frame 11 so as to cover the motor 12 and the communication circuit 13 as indicated by a chain line in the figure. In addition, the cover body 14 does not need to be dome-shaped, and can have a shape resembling the outer shape of the upper body of the character, for example. A ring-shaped restoration auxiliary body 15 is provided around the base frame 11 on the entire circumference. The restoration assisting body 15 assists restoration to a standing posture as will be described later when the jumping body lies sideways.

  The lower half 2 is provided with a circular base frame 21, and traveling wheels 22 are provided at the left and right positions thereof. Each traveling wheel 22 is rotated forward and backward by a motor 24 via a reduction gear 23. Guide posts 25 are erected in parallel at the front and rear positions of the base frame 21, and guide members 16 provided at the front and rear positions of the base frame 11 of the upper half 1 are slidably mounted on the guide posts 25. Yes. As a result, the base frame 11 of the upper half 1 can move relative to the base frame 21 of the lower half 2 in the approaching and separating directions while maintaining a parallel posture. In addition, a coil spring 4 as a biasing member is disposed between the base frames 11 and 21 in a compressed state, whereby the base frames 11 and 21 are biased in a relatively separated direction.

  A rod-like operation member 5 is provided with a lower end pivotably connected to the base frame 21, and an upper end 51 as a tip thereof is bent to enter into a guide hole 32 of the cam body 3 provided in the upper half 1. I have entered. In the state shown in FIG. 1, the upper end 51 of the operation member 5 is positioned at the other end 322 positioned below the guide hole 32 extending in the vertical direction, thereby restricting further separation of the base frame 11 from the base frame 21. ing.

  Legs 61 and 62 constituting an attitude adjustment mechanism are provided at the front and rear positions of the base frame 21. The leg bodies 61 and 62 are driven to project by an electromagnetic solenoid or the like. In FIG. 1, the front leg body 61 is projected so that the jumping body moves rearward with the traveling wheel 22 as a fulcrum by movement of the center of gravity. The leg 62 is grounded and the whole is inclined backward (to the right in the figure). When the rear leg 62 is operated to protrude, the jumping body is inclined forward until the front leg 61 comes into contact with the traveling wheel 22 as a fulcrum by the movement of the center of gravity. In addition, an operation rod 17 for assisting restoration as another operation member is provided (a chain line in FIG. 1), which protrudes upward through the top of the cover body 14, and the base end of the operation rod 17 is The cam body 3 is in contact with the outer periphery.

  Signals for forward / reverse rotation of the motors 12, 24 and protrusion control of the legs 61, 62, detection signals from various sensors that may be installed in the upper half 1, and output signals to speakers, The data is transmitted to and received from an external controller RC (FIG. 2) via a communication circuit 13 provided in the upper half 1. Of course, an artificial brain may be provided on the side of the jumping body so as to operate autonomously. A drive source such as an electromagnetic solenoid for projecting the motors 12 and 24 and the leg bodies 61 and 62 is supplied from the controller RC via the battery or the communication circuit 13 placed on the upper half 1.

  The operation of the jumping body having the above structure will be described below. By appropriately rotating the left and right traveling wheels 22 forward and backward, the jumping body can freely move forward and backward, turn, change direction, and move to a desired position. In the present embodiment, three types of jumps of high, medium, and low with different jump heights are possible. In the case of high jump, the cam body 3 is rotated clockwise from the state shown in FIG. 1 (solid arrow in the figure). As the cam body 3 rotates, the upper end of the operation member 5 moves in the guide hole 32 from the other end 322 toward the one end 321 (FIG. 3), and when the cam body 3 further rotates, the upper end 51 of the operation member 5 becomes the guide hole. It enters into the notch 323 formed at one end 321 of 32 and engages (FIG. 4).

  When the cam body 3 further rotates, the operation member 5 having the upper end 51 entering and engaging in the notch 323 of the guide hole 32 is largely pulled up (FIG. 5), and accordingly, the upper half 1 is moved to the lower half. The coil spring 4 is compressed while being moved downward so as to approach the body 2. When the cam body 3 further rotates from this state, the notch 323 turns obliquely downward, so that the upper end 51 of the operating member 5 that has received the urging force of the coil spring 4 escapes from the notch 323 and enters the guide hole 32. Is moved toward the other end 322 at once (FIG. 1). As a result, the coil spring 4 expands and moves the upper half 1 upward. As a result, a large inertial force acts upward, and the entire jumping body jumps high upward in the initial tilt direction.

  When the middle jump is performed, the cam body 3 is rotated counterclockwise (broken line arrow in the figure) from the state of FIG. As the cam body 3 rotates, the upper end 51 of the operating member 5 moves in the guide hole 32 along the oblique side 325, reaches the notch 324 at the intermediate position, and engages with this (FIG. 6). When the cam body 3 further rotates, the operation member 5 whose upper end 51 is engaged with the notch 324 is pulled up relatively large (FIG. 7), and accordingly, the upper half 1 approaches the lower half 2. And the coil spring 4 is compressed. When the cam body 3 further rotates from this state, the notch 324 faces obliquely downward, so that the upper end 51 of the operating member 5 that receives the urging force of the coil spring 4 escapes from the notch 324 and enters the guide hole 32. Is moved toward the one end 321 at once (FIG. 8). As a result, the coil spring 4 expands and moves the upper half 1 upward, and as a result, a relatively large inertial force acts upward, and the entire jumping body jumps up relatively rearward and upward.

  In the case of low jumping, the cam body 3 is rotated counterclockwise from the state shown in FIG. 1 to move the upper end 51 of the operating member 5 to the notch 324 at the intermediate position through the oblique side 325 of the guide hole 32. The movement of the operating member at this time causes the upper half 1 to move slightly downward so as to approach the lower half 2, and the coil spring 4 is slightly compressed accordingly. When the cam body 3 is rotated in the clockwise direction from this state, the upper end 51 of the operating member 5 that receives the urging force of the coil spring 4 moves again to the other end 322 of the guide hole 32 via the oblique side 325. Along with this, the coil spring 4 slightly expands and moves the upper half 1 upward, and as a result, an upward inertial force acts and the entire jumping body jumps downward and upward. It should be noted that each of the jumping motions of the jumping body as described above can be completed within one second.

  When the jumping body lies sideways after jumping, the jumping body is supported in an inclined posture with the outer periphery of the restoration assisting body 15 and the running wheels 22 and support legs 62 close thereto contacting the ground. In this case, if the cam body 3 is rotated to bring the upper half 1 closer to the lower half 2, the center of gravity of the upper half 1 approaching the lower half 2 and the restoration assistance that moves integrally therewith are moved. The jumping body is returned to the standing posture by the pushing-up force of the body 15. In the case where the jumping body after jumping is turned upside down, the operating rod 17 is pushed out by rotating the cam body 3 so that the outer periphery of the protruding portion 31 contacts the operating rod 17 (solid arrow in FIG. 9). The jumping body is laid down and returned to the standing posture.

(Other embodiments)
Various shapes as described below are conceivable for the outer shape of the cam body and the shape of the guide hole formed in the cam body. 10 (1), a linear guide hole 71 is formed on the plate surface of the cam body 3, and the guide hole 71 is not formed with the notch in the first embodiment. As the cam body 3 rotates, the upper end 51 of the operating member 5 moves in the guide hole 71, and accordingly, the coil spring 4 is compressed and then expanded, and the jumping body jumps up.

  10 (2), a straight guide hole 72 is formed on the plate surface of the cam body 3, and a notch 721 similar to the notch in the first embodiment is formed at one end of the guide hole 72. ing.

  In the one shown in FIG. 11 (4), one side edge of the guide hole 78 is bulged and curved in an arc shape. This also facilitates the movement of the operating member upper end 55 in the guide hole 78, and can reduce the required torque of the motor 12 that rotates the cam body 3.

  The external shape of the cam body 3 can be made into various shapes according to the purpose as shown in FIGS. In this case, for example, an operation bar for operating an arm or other functional member provided in the jumping body can be brought into contact with the outer periphery of the cam body 3 instead of the operation bar 17 for restoring assistance, for example.

  As shown in FIGS. 13 (1) and 13 (2), a plurality of cam bodies 3A and 3B having different outer shapes are provided, the upper end 55 of the operating member is positioned in the guide holes 76 and 79, and the operating rod 17 for assisting restoration is provided. Further, an operating rod for operating other functional members may be brought into contact with the outer circumferences of the cam bodies 3A and 3B.

  14 (1) and 14 (2), ring-shaped guide holes 81 and 82 are formed point-symmetrically or line-symmetrically on the plate surface of the cam body 3. In this case, a coil spring similar to the coil spring 4 above the upper half 1 in the first embodiment, a half having the same structure as the lower half 2, an operation member similar to the operation member 5, and the like. Is provided. Then, the upper and lower ends of the upper and lower operation members are positioned in the guide holes 81 and 82, respectively. According to this, even when the jumping body is turned over and reversed, it can be moved and jumped as it is without being reversed and restored to the original position.

In each of the above embodiments, the guide portion provided on the cam body is not necessarily a guide hole. It is not always necessary to provide the lower half of the traveling wheel. In this case, the jumping direction can be set arbitrarily by providing a posture adjustment mechanism that can adjust the tilting posture before jumping not only in the front-rear direction but also in the left-right direction. It is good to make it.
