  In a conventionally proposed traveling toy system, imitation toys that can be mounted on a moving body (a towed body or a self-propelled carriage) are limited to dedicated products. Therefore, in the conventional traveling toy system, different types of imitation toys cannot be traveled unless a dedicated product is purchased. However, if you can run your own imitation toys such as automobiles supported by the towed body, you will not only increase the utilization of the toy system, but also enjoy the collection of imitation toys such as cars. A synergistic effect of increasing is obtained. However, in the conventional traveling toy system, there is a problem that if the imitation toy can be modified, it is practically impossible to support the imitation toy on the trailer or the self-propelled carriage. Modifying a commercial imitation toy is not acceptable for many toy collectors.

  An object of the present invention is to provide a traveling toy system capable of traveling in a state where a track member is supported on a to-be-to-be-drawn body without modifying a commercially available imitation toy.

  In addition to the above object, another object of the present invention is to provide a traveling toy system that can prevent an imitation toy having wheels from falling off from a towed body.

  In addition to the above object, another object of the present invention is to provide a traveling toy system in which the towed body does not easily fall down.

  The traveling toy system of the present invention includes a track member, a self-propelled tow vehicle that includes a drive source and self-travels on the track member, and is pulled by the self-propelled tow vehicle via a coupling mechanism to travel on the surface of the track member. And a towed body. The track member may be configured as a single component, or may be configured by combining a plurality of components. The drive source of the self-propelled tow vehicle is generally an electric motor. The electric motor may be configured to drive the battery so as to operate using the battery as a power source. However, when the track member is provided with an energization path, it is needless to say that the drive device may be configured to drive the electric motor with electric power supplied from the energization path. As with so-called slot cars, self-propelled towed vehicles may be capable of operation control by a controller, but they may be driven / non-driven only by turning on / off the switch and not controlled. Good. The control method of the self-propelled tow vehicle capable of operation control may be the same as that used in known slot car toys.

  In this invention, the to-be-towed body is equipped with the attachment which has a some engaging part which engages with the commercially available imitation toy which is not remodeled, and supports a commercially available imitation toy. And the attachment is comprised so that the positional relationship of a some engaging part can be changed according to the dimension of a commercially available imitation toy. The plurality of engaging portions may have any shape or structure as long as they can partially engage with a commercially available imitation toy that has not been modified (including fitting) and can support the imitation toy. May be. Ideally, it is preferable that the engagement between a part of the dummy toy and the plurality of engaging portions is completed only by placing the dummy toy on the attachment (or simply placing the dummy toy on the attachment). .

  According to the present invention, since the self-propelled tow vehicle runs on the track member and the to-be-towed body travels on the track member, the illusion that an imitation toy supported by the to-be-to-be-to-be-driven body is self-running is seen. Can be given to a person. In particular, according to the present invention, by changing the positional relationship of the plurality of engaging portions of the attachment, the imitation toy having various sizes can be supported on the to-be-drawn body without modification. Therefore, according to the present invention, it is possible to run the imitation toy on the track member without damaging (without modifying) the imitation toy owned by the user. In the present invention, since the track member of the existing slot car toy and the control device for the traveling vehicle can be used as they are, it can be used as an optional toy of the existing slot car toy.

  The coupling mechanism includes a coupling shaft portion extending in the vertical direction, and a relative rotational motion is generated between the self-propelled tow vehicle and the to-be-towed body during traveling around the coupling shaft portion. Preferably, it is configured. If the coupling mechanism has such a configuration, even if the self-propelled towed vehicle travels while meandering, the relative rotation centering on the coupling shaft portion between the self-propelled towed vehicle and the to-be-towed body. Since a dynamic motion occurs, the to-be-towed body cannot be pulled.

  Moreover, it is preferable that the exterior case of the self-propelled tow vehicle has a color that is the same as or close to the color of the surface of the track member. In this way, when the self-propelled tow vehicle is traveling on the track member, the self-propelled tow vehicle becomes assimilated with the track member, giving the viewer the illusion that no self-propelled tow vehicle exists. Can be given. Therefore, it is possible to give a person who sees the illusion that only the imitation toy that he owns is traveling on the track member.

  For example, it is assumed that a commercially available imitation toy is an imitation toy for a vehicle (two-wheeled vehicle, three-wheeled vehicle, four-wheeled vehicle, etc.) in which one or more wheels are mounted on a plurality of axles. In this case, it is preferable that the plurality of engaging portions of the attachment are configured to engage with the plurality of axles, respectively. If such an engaging part is used, an engaging part will be located inside the wheel fixed to the axle, and will engage with an axle. Therefore, the imitation toy which has a wheel can be reliably mounted | worn in the state which does not move on a to-be-towed body. Further, since the engaging portion that engages with the axle is covered with the wheel, there is an advantage that the rate of awareness of the presence of the to-be-towed body during traveling is reduced.

  Although the wheel of the imitation toy may be brought into contact with the surface of the track member, in many imitation toys for vehicles, the direction of the axle cannot be changed. For this reason, when the to-be-to-be-driven body travels in a state where the wheels are in contact with each other, the wheels themselves may become a resistance, for example, a state where drift traveling or the like cannot be performed. Therefore, it is preferable that the to-be-towed body is configured so that the wheel of the imitation toy does not come into contact with the surface of the track member in a state where the commercially available imitation toy is supported by the attachment.

  The plurality of engaging portions that engage with the axle are respectively configured to have a groove portion that opens toward both the upper side and the lateral direction, and includes a groove portion into which the axle is inserted from the opening portion that opens upward. preferable. When the plurality of engaging portions are configured in this manner, the axle can be easily engaged with the plurality of engaging portions only by performing an operation of placing the imitation toy of the vehicle on the towed body. As a result, the imitation toy of the vehicle can be easily replaced with the to-be-towed body placed on the track member.

  In the case where the commercially available imitation toy is a four-wheeled vehicle imitation toy in which two wheels are mounted on the front axle and the rear axle, respectively, the attachment is preferably configured as follows. That is, the attachment is configured so that the positional relationship of the plurality of engaging portions can be changed in accordance with the difference in the tread dimension between two wheels fixed to both ends of one axle and the wheel base dimension between the two axles. It is preferable to do this. If it does in this way, it becomes possible to support the toy body simply and reliably the imitation toy of a plurality of types of vehicles having different tread dimensions and wheel base dimensions. The specific attachment structure in this case is preferably as follows. That is, the attachment can have a structure including a first structural member, a second structural member, and an adjustable coupling mechanism. The first structural member has two engaging portions that engage with two adjacent wheels and two end portions adjacent to the front axle, a first support body, and a function capable of adjusting a dimension between the two engaging portions. And two engagement portion support mechanisms for supporting the two engagement portions on the first support. In addition, the second structural member can adjust the dimensions between the two engaging portions that engage the two end portions adjacent to the two wheels of the rear axle, the second support body, and the two engaging portions. And two engagement portion support mechanisms for supporting the two engagement portions on the second support. The adjustable connecting mechanism is configured to connect the first structural member and the second structural member with a function capable of adjusting the distance between them. In this attachment, the dimension (tread dimension) between the two engaging parts can be adjusted by the adjusting function of the engaging part support mechanism, and the first structural member and the second structural member can be adjusted by the adjustable coupling mechanism. Can be adjusted. The structure of the engaging portion support mechanism is arbitrary. For example, when a four-joint parallel link mechanism is used as the engaging portion support mechanism, the position of the engaging portion can be easily adjusted by performing an operation of sliding the engaging portion along the surface of the upper track member. it can. Further, since the engaging portion is supported by the two links, the mechanical strength of the engaging portion supporting mechanism can be increased. The adjustable connecting mechanism includes an elongated frame, and one of the first support and the second support is fixed to the frame, and the other of the first support and the second support slides on the frame. What has the structure mounted | worn possible can be used. By using the adjustable connecting mechanism of this structure, it is possible to easily adjust the dimension (wheel base dimension) between the first structural member and the second structural member by sliding the support along the frame. it can. Further, since the frame exists, the mechanical strength can be ensured.

  The adjustable coupling mechanism includes a first frame half portion to which the first support body is fixed, and a second frame half portion to which the second support body is fixed. You may use what has the structure where the flame | frame half part was connected so that sliding was possible. When such an adjustable coupling mechanism is used, a dimension between the first structural member and the second structural member (wheel base dimension) is obtained by performing a sliding motion between the first and second frame halves. Can be adjusted easily.

  The configuration of the track member and the configuration of the self-propelled tow truck are arbitrary. Of course, the configuration adopted in the so-called slot car on the market may be used as it is. Specifically, the track member may be provided with a guide groove portion continuous along the track and a pair of power supply rail members arranged on both sides of the guide groove. The self-propelled tow truck includes a tow truck main body having a drive source, a drive axle that is provided on the rear side of the tow truck main body and driven by the drive source, and is attached to both ends of the drive axle to rotate on the track member. It is possible to use one provided with a pair of driving wheels that move, and a pin member that is provided at a position ahead of the driving axle of the bottom surface portion of the towing vehicle main body and is fitted into the guide groove portion. In order to supply power to the drive source, a pair of brush members provided in the vicinity of the pin member and in contact with the pair of rail members are provided.

  The structure of the engaging portion that engages with the axle of the imitation toy of the vehicle is, for example, a plate formed integrally with a plate-like portion having the above-described groove portion into which the axle fits and a lower end portion of this plate-like portion. And a base extending in a direction orthogonal to the shape portion. In this case, the first and second nodes of the aforementioned four-node parallel link mechanism are provided on the base, and the third and fourth nodes of the four-node parallel link mechanism are provided on the support. Preferably, at least one of the first and second supports is provided with a pin member that is inserted into a guide groove provided on the track member. If such a pin member is provided on at least one of the first and second support bodies, the movement of the towed vehicle can be made to follow the movement of the self-propelled towed vehicle, and the towed body falls over. It can be effectively prevented.

  According to the present invention, since the self-propelled tow vehicle runs on the track member and the to-be-towed body travels on the track member, the illusion that an imitation toy supported by the to-be-to-be-to-be-driven body is self-running is seen. Can be given to a person. In particular, according to the present invention, by changing the positional relationship of the plurality of engaging portions of the attachment, the imitation toy having various sizes can be supported on the to-be-drawn body without modification. Therefore, according to the present invention, it is possible to run the imitation toy with the track member without damaging (without modifying) the imitation toy owned by the user. In the present invention, since the track member of the existing slot car toy and the control device for the traveling vehicle can be used as they are, it can be used as an optional toy of the existing slot car toy.

  Embodiments of a traveling toy system according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration of an example of an embodiment of a traveling toy system 1, and FIG. 2 is a self-propelled tow vehicle used in the traveling toy system 1 of FIG. FIG. 3A is an enlarged perspective view of a to-be-towed body to be pulled, and FIGS. 3A and 3B are a perspective view of a self-propelled tow vehicle and a perspective view seen from the bottom side. In these drawings, the traveling toy system 1 includes a track member 3, a self-propelled tow vehicle 5, and a to-be-towed body 7. As shown in FIG. 1, the track member 3 has the same structure as a known slot car toy truck, and two annular guide grooves 9 are formed in an insulating resin plate member 8. Yes. The plate member 8 is provided with two power supply rail members 11 and 13 along the guide groove 9. Two power supply rail members 11 and 13 are arranged along the plate member 8 and the guide groove 9. One of the two power supply rail members 11 and 13 is a plus electrode, and the other is a minus electrode. A DC voltage is applied to the power supply rail members 11 and 13 from the driving device 15 shown in FIG. In FIG. 1 and FIG. 2, the electrical wiring is not shown. As shown in FIG. 1, by operating buttons 19 and 19 '(hereinafter simply referred to as buttons 19) of 17 and 17' (hereinafter simply referred to as throttle 17) used by the two players, respectively. The operation of two self-propelled carts 5 and 5 ′ (hereinafter simply referred to as self-propelled carts 5) is controlled separately. The operation control of the self-propelled tow vehicle 5 is the same as the operation control method used in a known slot car toy. For example, when the button 19 is pressed, the corresponding self-propelled tow vehicle 5 moves, the speed of the self-propelled tow vehicle 5 increases according to the amount of operation of the button 19, and when the button 19 is released, the self-propelled tow vehicle 5 stops. . The structure of the self-propelled towing vehicle 5 will be described in detail later.

  Next, the self-propelled tow vehicle 5 used in the present embodiment will be described with reference to FIG. 1 focusing on FIG. 2 and FIGS. 3 (A) and 3 (B). The self-propelled tow vehicle 5 includes a drive source in the tow vehicle main body 6 and self-travels on the track member 3. The driving source of the self-propelled towing vehicle 5 is an electric motor (not shown). In the present embodiment, the drive device that drives the electric motor is configured to drive the electric motor by the electric power supplied from the power supply rail members 11 and 13 serving as the energization paths provided in the track member 3. . As shown in FIG. 3 (B), the self-propelled tow vehicle 5 is further provided with a drive axle 23 provided on the rear side of the towing vehicle body 6 and driven by a drive source, and attached to both ends of the drive axle 23. A pair of drive wheels 25 that rotate on the member 3 are provided. Further, a pin member 27 is fixed to the bottom surface portion of the towing vehicle body 6 at a position on the front side of the drive axle 23 and fitted in the guide groove portion 9 shown in FIG. In addition, a pair of brush members 29 that come into contact with the pair of power supply rail members 11 and 13 are provided on the bottom surface of the tow vehicle main body 7 in order to supply power to the drive source. DC power is supplied from the brush members 29 to the drive device in the tow vehicle main body 6.

  The plate-like portion 30 provided at the rear end portion of the towing vehicle main body 6 is provided with a connecting shaft portion 33 extending in the vertical direction in order to constitute a part of the connecting mechanism 31. A head 35 for retaining is integrally provided at the upper end of the connecting shaft 33. As will be described in detail later, the connecting plate 56 provided in front of the to-be-towed body 7 has a through-hole 37 through which the head 35 for retaining and the elongated through-hole 39 through which the connecting shaft portion 33 slides. The combined hole 40 is formed. By fitting the connecting shaft portion 33 and the through hole 39 of the hole portion 40, the relative rotation between the self-propelled tow vehicle 5 and the to-be-towed body 7 during traveling is performed with the connecting shaft portion 33 as the center. Dynamic movement occurs. When the coupling mechanism 31 has such a configuration, even if the self-propelled tow vehicle 5 runs while meandering, the coupling shaft portion 33 is centered between the self-propelled tow vehicle 5 and the to-be-towed body 7. As a result, a relative rotational movement occurs, so that the pulled object 7 cannot be pulled. The structure of the coupling mechanism 31 is not limited to the present embodiment. In the present embodiment, the exterior case of the self-propelled carriage has a color that is the same as or similar to the color of the surface of the track member 3. In this way, when the self-propelled carriage is traveling on the track member, the self-propelled carriage is assimilated with the track member, giving the viewer the illusion that there is no self-propelled carriage. it can. Therefore, it is possible to give a person who sees the illusion that only the imitation toy that he owns is traveling on the track member. However, it goes without saying that the color of the exterior case of the self-propelled carriage may be a color other than the color that is the same as or similar to the color of the surface of the track member 3.

  Next, the to-be-towed body 7 that is towed by the self-propelled towing vehicle 5 on the track member 3 will be described in detail with reference to FIGS. 4 (A) to 4 (D) are perspective views of the towed body 7 as viewed from the front side, a perspective view of the towed body 7 as viewed from the back side, a bottom view of the towed body 7 and the like used in the present embodiment. It is a side view. The to-be-towed body 7 has four engaging portions 41A that partially engage with a commercially available imitation toy [in this embodiment, an imitation toy IT of a four-wheeled vehicle in FIG. 4D] that has not been modified. The attachment 43 with thru | or 41D is provided. The attachment 43 is configured so that the positional relationship of the four engaging portions 41 can be changed according to the dimensions of a commercially available imitation toy IT. The four engaging portions 41A to 41D have any shape as long as they can partially engage (including fitting) with a commercially available imitation toy IT that has not been modified and can support the imitation toy. Or it may be a structure. In this example, by simply placing an imitation toy on the attachment 43 (or simply placing an imitation toy on the attachment 43), the engagement of a portion of the imitation toy and the four engagement portions 41A to 41D is completed. Thus, the structure of the engaging portion 41 is determined.

  The commercially available imitation toy IT targeted by the attachment 43 is an imitation toy for a four-wheeled vehicle in which two wheels are respectively attached to two axles as shown by a broken line in FIG. Therefore, the four engaging portions 41A to 41D of the attachment 43 are configured to engage with the two axles S1 and S2 (see FIG. 4), respectively. When these engaging portions 41A to 41D are used, the engaging portions 41A to 41D are located inside the wheels H (see FIG. 4D) fixed to the axles S1 and S2 and are engaged with the axles S1 and S2. Will match. Therefore, the imitation toy IT having a car can be securely mounted on the to-be-to-be-towed body 7 without moving. In addition, since the engaging portions 41A to 41D that engage with the axles S1 and S2 are covered with the wheels H, the rate at which the person who sees the to-be-to-be-towed body 7 is aware of the existence of the to-be-to-be-towed body 7 is high. Less.

  Although the wheel of the imitation toy of a four-wheeled vehicle may be brought into contact with the surface 3C of the track member 3, the orientation of the axle cannot be changed in the imitation toy of many vehicles. Therefore, when the to-be-towed body 7 travels in a state where the wheels are in contact with each other, the wheels themselves may become resistance, for example, a state where drift traveling or the like cannot be performed. Therefore, it is preferable that the to-be-towed body 7 used in the present embodiment is configured so that the wheels of the imitation toy do not come into contact with the surface of the upper track member while the commercially available imitation toy is supported by the attachment 43. Therefore, in the to-be-towed body 7, the four engaging portions 41A to 41D engaged with the axle are respectively provided with a plate-like portion 42 having a groove portion 47 into which the axle is fitted, and a lower end portion of the plate-like portion 42. A base 44 that is integrally formed and extends in a direction orthogonal to the plate-like portion 42 is provided. The groove portion 47 has a structure that opens toward both sides in the upward direction and the lateral direction, and the axle is inserted through the opening portion 45 that opens upward. When the four engaging portions 41A to 41D are arranged in this way, the two axles can be moved into the two engaging portions 41A and 41B, 41C It can be easily engaged with 41D. As a result, the imitation toy IT of the vehicle can be easily replaced with the to-be-towed body 7 placed on the track member 3.

  The attachment 43 used in the present embodiment is a dedicated attachment for supporting a counterfeit toy of a four-wheeled vehicle in which a commercially available imitation toy is equipped with two wheels on the front axle and the rear axle, respectively. The attachment 43 can change the positional relationship of the four engaging portions 41A to 41D according to the difference in the tread dimension between the two wheels fixed to both ends of one axle and the wheel base dimension between the two axles. It is configured as follows.

  Specifically, the attachment 43 includes a first structural member 49, a second structural member 51, and an adjustable connection mechanism 53. The first structural member 49 includes two engaging portions 41A and 41B that engage with both end portions adjacent to the two wheels H of the front axle S1 (FIG. 4), a first support 55, and two Two engagement portion support mechanisms 57A and 57B that support the two engagement portions 41A and 41B on the first support body 55 with a function capable of adjusting the dimension between the engagement portions 41A and 41B are provided. . A connecting plate 56 is fixed to the upper surface of the first support body 55. The second structural member 51 includes two engaging portions 41C and 41D that engage with both end portions adjacent to the two wheels of the rear axle S2 [FIG. 4D], a second support body 59, and the like. Two engagement portion support mechanisms 57C and 57D are provided that support the two engagement portions 41C and 41D on the second support body 59 so that the dimension between the two engagement portions 41C and 41D can be adjusted. The adjustable connecting mechanism 53 is configured to connect the first structural member 49 and the second structural member 51 with a function capable of adjusting the distance between them. In the attachment 43, the dimension (tread dimension) between the two engagement parts 41A and 41B and between the two engagement parts 41C and 41D can be adjusted by the adjustment function of the engagement part support mechanisms 57A to 57D. Moreover, the dimension (foil base dimension) between the 1st structural member 49 and the 2nd structural member 51 can be adjusted with the adjustable connection mechanism 53. FIG. The structure of the engaging portion support mechanisms 57A to 57D is arbitrary. 5A to 5E show a plurality of variations in the case where the positional relationship between the four engaging portions 41A to 41D is changed using the four engaging portion support mechanisms 57A to 57D.

  As shown in FIG. 5, in the present embodiment, a four-node parallel link mechanism in which four links are connected by four nodes is used as the engaging portion support mechanisms 57A to 57D. As a result, by adjusting the position between the two engaging portions by adjusting the two engaging portions 41A and 41B or the two engaging portions 41C and 41D along the surface of the track member 3, the tread size is adjusted. ) Can be done easily. Further, in the four-node parallel link mechanism used in the present embodiment, the first and second nodes J1 and J2 of the four-node parallel link mechanism are provided on the base 44, as represented by a symbol in FIG. The third and fourth nodes J3 and J4 of the four-node parallel link mechanism are provided on the support 55. Since the base 42 is supported by the two links L1 and L2, the mechanical strength of the engagement portion support mechanisms 57A and 57D can be increased.

  Further, in the present embodiment, convex portions 61 that slide on the surface 3C are formed on the back surface of the base 44 and the back surface of the second support body 59 facing the surface 3C of the track member 3, respectively. In this way, the track member 3 is in a state in which the convex portions 61 provided on the back surface of the base 42 of the four engaging portions 41A to 41D and the convex portions 61 provided on the back surface of the second support body 59 are widely dispersed. In contact with the surface 3C. As a result, even when the trailer 7 travels on the surface 3C of the track member 3 at high speed, the trailer 7 does not tilt or fall over. Moreover, since the to-be-to-be-towed object 7 is supported by the substantial point contact by the some convex part 61, frictional resistance does not become large remarkably. Further, when a plurality of convex portions 61 are used as in the present embodiment, the presence of the to-be-to-be-towed body 7 is less conspicuous than the case in which the to-be-to-be-towed body 7 is provided with wheels and rollers.

  In the present embodiment, pin members 60 fitted into the guide groove portions 9 are integrally provided on the back surfaces of the first support body 55 and the second support body 59, respectively. The pin member 60 may be provided on at least one of the first and second support bodies 55 and 59. If such a pin member 60 is provided on at least one of the first and second supports 55 and 59, the movement of the towed vehicle 7 can be made to follow the movement of the self-propelled towing vehicle 5 and the towed object can be pulled. It is possible to effectively prevent the body 7 from falling.

  The adjustable connection mechanism 53 of the attachment 43 includes an elongated frame 63. The first support member 55 of the first structural member 49 is fixed to one end of the frame 63, and the second support member 59 of the second structural member 51 is slidably mounted on the frame 63. When the adjustable connecting mechanism 53 having such a structure is used, as shown in FIGS. 6A to 6C, the first structural member 49 is moved by the sliding motion of the second support body 59 along the frame 63. And the dimension between the second structural member 51 (wheel base dimension) can be easily adjusted. Further, since the frame 63 exists, the mechanical strength can be ensured.

  As shown in FIG. 7, the adjustable connecting mechanism 53 includes a first frame half 63A to which the first support 55 is fixed, and a second frame half to which the second support 59 is fixed. A portion 63B may be used, and the first and second frame halves 63A and 63B may be slidably connected. In the example shown in FIG. 7, a slit 64B is formed in the second frame half 63B, and a pin member 64A that slides in the slit 64B is fixed to the end of the first frame half 63A, so that the connection structure is It is configured. With such an adjustable coupling mechanism, the dimension between the first structural member 49 and the second structural member 51 is achieved by performing a sliding motion between the first and second frame halves 63A and 63B. (Wheelbase dimensions) can be easily adjusted.

  Furthermore, the structure of the attachment of the to-be-towed body 7 used in the above embodiment is a dedicated structure for holding a four-wheeled vehicle imitation toy. The structure of the attachment may be appropriately determined according to the shape or structure of the imitation toy to be supported. Further, the structure of the self-propelled tow vehicle is not limited to the above embodiment.

It is a figure which shows the structure of an example of embodiment of the traveling toy system of this invention. It is the perspective view which expanded and showed the self-propelled tow vehicle used with the traveling toy system 1 of FIG.
