TECHNICAL FIELD

[0001] The utility model relates to a track toy, especially a track toy for self-propelled vehicle running. BACKGROUND

[0002] In the past, a track toy is known which has an operation member, a track switching member, and an action device (see Patent Document 1). The operation member is provided at a branching point at which a plurality of tracks branch from a basic track, and is caused to act by collision of a self-propelled vehicle toy passing through the branching point; the track switching member is configured to be able to switch and selectively connect the basic track and each of the plurality of tracks by switching; and the action device switches the track switching member by power of the operation member.

[0003] The track switching member of the track toy is configured to change the direction of the track switching member by pushing either of arm pieces (operation members) provided on both sides of a first track with an action piece of the vehicle toy via a link piece connected to the arm pieces. According to the track toy, the track switching member is switched every time the vehicle toy passes through the branching point from the first track, so the vehicle toy can be alternately guided to the two tracks.

[0004] Patent Document 1: Japanese Patent No. 33-10916

[0005] However, according to the track toy, the track switching member is switched at the point in time when the arm pieces are pushed by the action piece of the vehicle toy. Therefore, in a case where a vehicle is connected after the vehicle in which the action piece is formed, since the track switching member is to be switched before the entire vehicle toy passes, the vehicle toy and the track switching member interfere with each other, and it is difficult to properly perform track guidance. In addition, after the vehicle toy passes through, for example, an intersection, the action device needs to act at an appropriate timing.

[0006] The utility model is completed in view of the above situation, and the purpose is to provide a track toy capable of causing an action member to act at an appropriate timing. SUMMARY

[0008] The second track toy is provided with an operation member, an action device, and a track switching member, wherein the operation member is arranged at a branch point where a plurality of tracks branch from a basic track, and the action device is arranged at the basic track, and the action device is arranged to be actuated by the operation member, and the track switching member is arranged to be actuated by the action device.

[0009] The third track toy is provided with an intermittent motion mechanism and a motion conversion mechanism, wherein the intermittent motion mechanism is arranged to rotate a rotating body by a predetermined angle in one direction each time a vehicle toy from the basic track passes through the branch point.

[0010] The fourth track toy is provided with a cam mechanism and a connecting rod mechanism, wherein the cam mechanism is arranged to convert the rotating motion of the rotating body into the rotating motion of one connecting rod, and the connecting rod mechanism is arranged to convert the rotating motion of the one connecting rod into the conversion motion of the track switching member.

[0011] The fifth track toy is provided with the track switching member on the same first shaft as the output connecting rod of the connecting rod mechanism, and the output connecting rod and the track switching member are connected via a torsion spring wound on the first shaft.

[0012] The sixth track toy is provided with an action area of the sliding contact guide and an action area of the operation member in an interference state when viewed from above, and the operation member is arranged to act at a position higher than the sliding contact guide.

[0013] The seventh track toy is provided with an action area of the operation member containing an action area of the sliding contact guide when viewed from above.

[0025] Hereinafter, the track toy of the embodiment of the present application will be described using the drawings.

[0026] SUMMARY

[0027] Figures 1 to 3 is a perspective view showing the main part (bifurcation) of the track toy 100 of the embodiment. The track toy 100 relates to a self-propelled vehicle toy 50, and particularly relates to a bifurcation through which a train toy travels. The track toy 100 is provided with a bifurcation point BP that bifurcates from a first runway 10 into two second runways 11, 12.

[0028] According to the track toy 100, when the vehicle toy 50 entering the branch point BP from the first raceway 10 side collides with the operation member CM, the operation member CM in the initial state rotates counterclockwise in plan view and retreats from the road surface Figure 2 ). Also, the vehicle toy 50 is guided to the second raceway 12 by the raceway switching member RSM. Then, the operation member CM is in sliding contact with the side surface of the vehicle toy 50 before the vehicle toy 50 passes the prescribed place, maintaining the retreat state.

[0029] Also, when the vehicle toy 50 passes the prescribed place, the operation member CM returns from the retreat state to the initial state. At this time, the raceway switching member RSM is switched, changing the direction Figure 3 ). Thus, the next vehicle toy 50 entering the branch point BP from the first raceway 10 is guided to the second raceway 11 this time by the switched raceway switching member RSM.

[0030] On the other hand, in the case where the vehicle toy 50 enters the branch point BP from the second raceway 11, 12 side, regardless of the switching state of the raceway switching member RSM, the vehicle toy 50 passes the place of the raceway switching member RSM, collides with the operation member CM, and the operation member CM in the initial state rotates clockwise in plan view and retreats from the road surface. Then, the operation member CM is in sliding contact with the side surface of the vehicle toy 50 before the vehicle toy 50 passes the place of the operation member CM, maintaining the retreat state. Then, when the vehicle toy 50 passes the place of the operation member CM, it returns to the initial state. At this time, the raceway switching member RSM is not switched.

[0031] Details

[0032] (Operation member CM)

[0033] Figure 4 is an exploded perspective view of the operation member CM, Figure 5 is an exploded perspective view of the operation member CM viewed from below. The operation member CM is configured to be rotatable about a prescribed vertical axis beside the first raceway 10. The operation member CM extends in a direction transverse to the first raceway 10. The base end portion of the operation member CM is a cover 14 covering the shaft portion 15, and a recess opened below the cover 14 is provided with an engagement protrusion 14a. This operation member CM is detachable with respect to the shaft portion 15 from the track disk 100A.

[0034] (Shaft portion 15)

[0035] The shaft portion 15 has a shaft body 15a, two washers 16a, 16b, a coil spring 17, an output rotating body 18, and a torsion spring 19. At the upper end of the shaft body 15a, a large-diameter circular plate-shaped fitting portion 15b is provided which fits into the recess of the cover 14. The fitting portion 15b is provided on the track disk 100A. Further, a fitting recess 15c is formed in the fitting portion 15b. The fitting projection 14a is fitted in the fitting recess 15c, and the operation member CM and the shaft body 15a are integrally rotated.

[0036] The rod-shaped portion 15d of the shaft body 15a penetrates the upper wall of the track disk 100A and extends to the inside of the track disk 100A. The rod-shaped portion 15d is inserted into the central hole 18a of the output rotating body 18 after passing through the washer 16a, the coil spring 17, and the washer 16b in this order from above. At this time, the ridge 15f formed in the rod-shaped portion 15d is engaged with the groove 18b of the output rotating body 18. By this engagement, the output rotating body 18 is integrally rotated with the rod-shaped portion 15d and can move in the axial direction of the rod-shaped portion 15d. Further, an internal thread (not shown) is cut in the lower end portion of the rod-shaped portion 15d, and an external thread 15g which is inserted into a through hole (not shown) of the lower wall of the track disk 100A from below is screwed into the internal thread. Thus, the shaft portion 15 is mounted on the track disk 100A.

[0037] Further, a tab 18c which is triangular in cross section and projects downward is formed at the eccentric position of the output rotating body 18.

[0038] The two washers 16a, 16b are sandwiched between the upper wall of the track disk 100A and the output rotating body 18. The coil spring 17 which is wound around the rod-shaped portion 15d is provided between the two washers 16a, 16b. The output rotating body 18 is urged downward by the coil spring 17.

[0039] Further, the torsion spring 19 is wound around the output rotating body 18, one end of the torsion spring 19 is hung on the output rotating body 18, and the other end of the torsion spring 19 is fixed to the fixed portion of the track disk 100A. By the torsion spring 19, the operation member CM is urged toward the initial position.

[0040] (Runway switching member RSM)

[0041] The runway switching member RSM is configured to be rotatable about the shaft 35a. The shaft 35a is located on the side of the runway 12, and the runway switching member RSM acts only on the runway 12.

[0042] Further, when the runway switching member RSM acts toward the side of the runway 11, as shown in FIG. 6, the tab 18c of the output rotating body 18 is engaged with the engaging recess 35b of the shaft 35a, and the output rotating body 18 is rotated in the direction of the arrow A2. Figure 1As shown, the front end of the track switching component RSM enters the surface of the basic track 10, and one side of the track switching component RSM slides into contact with the inner surface of the left wheel of the toy vehicle 50 entering the bifurcation point BP from the side of the basic track 10, guiding the toy vehicle 50 towards the track 12 side. Conversely, when the track switching component RSM moves towards the track 12 side, as... Figure 3 As shown, the front end of the track switching component RSM exits from the surface of the basic track 10, and the other side of the track switching component RSM slides into contact with the outer surface of the left wheel of the toy vehicle 50 entering the bifurcation point BP from the side of the basic track 10, guiding the toy vehicle 50 towards the track 12 side. In this case, the other side of the track switching component RSM is approximately coplanar with the inner surface of the side wall of the basic track 10 and track 11.

[0043] (Action Device 20)

[0044] Figure 6 This is a perspective view of the actuation device 20 of the runway switching component RSM. Figure 7 This is a bottom view of the actuation device 20. Figure 8 This is a bottom view of the intermittent motion mechanism 20A.

[0045] The actuation device 20 has an intermittent motion mechanism 20A, which transforms the rotational motion of the operating component CM into an intermittent rotational motion in one direction.

[0046] The intermittent motion mechanism 20A has a rotating body 21 that is approximately hexagonal in shape when viewed from above, and an anti-rotation member 25 that stops the rotation of the rotating body 21 at each 60-degree point.

[0047] like Figure 8 As shown, on the top of the rotating body 21, there are six pins 22, one near each of the six corners. The upper surface of the pin 22 is an inclined surface 22a that slopes down in a specified direction (see reference). Figure 6 Additionally, a claw 23 is formed at one end of each side of the rotating body 21.

[0048] The anti-rotation member 25 can rotate around the shaft 25a. Through the force of the helical spring 26, its front end abuts against the outer periphery of the rotating body 21. By abutting against each side of the rotating body 21, the rotating body 21 is held at a specified angle.

[0049] Furthermore, the front end of the anti-rotation member 25 can engage with the claw 23 of the rotating body 21 as the rotating body 21 rotates. This engagement prevents the rotating body 21 from reversing. That is, when the rotating body 21 is to rotate clockwise when viewed from above, the front end of the anti-rotation member 25 locks the claw 23 in place. Thus, the rotation of the rotating body 21 is stopped by the anti-rotation member 25. On the other hand, when the rotating body 21 rotates counterclockwise, the claw 23 springs off the anti-rotation member 25. Thus, the claw 23 of the rotating body 21 overcomes the force of the coil spring 26 and passes over the front end of the anti-rotation member 25.

[0050] Furthermore, the rotation path of pin 22 overlaps with the rotation path of the tab 18c of the output rotating body 18 when viewed from above. As the output rotating body 18 rotates, pin 22 engages with tab 18c. When the output rotating body 18 rotates clockwise when viewed from above, tab 18c presses against pin 22. As a result, rotating body 21 rotates counterclockwise when viewed from above. On the other hand, when the output rotating body 18 rotates counterclockwise when viewed from above, tab 18c slides into contact with inclined surface 22a. As a result, output rotating body 18 moves upward against the force of coil spring 17, and tab 18c passes over pin 22.

[0051] (Motion conversion mechanism 20B)

[0052] The actuation device 20 has a motion conversion mechanism 20B that converts the rotational motion of the rotating body 21 into the conversion motion of the runway switching component RSM. The motion conversion mechanism 20B has a cam mechanism 31 and a linkage mechanism 32.

[0053] like Figure 7 As shown, the cam mechanism 31 has three protrusions (primary links) 30a formed on the lower surface of the rotating body 21 and extending radially from the shaft 21b of the rotating body 21, and a first ring (secondary link) 33 constituting the linkage mechanism 32. The three protrusions 30a are arranged at equal intervals in the circumferential direction of the rotating body 21. In addition, the middle part of the first link 33 is supported by the track disk 100A via the shaft 33a, and one end abuts against the protrusions 30a by the force of the coil spring 33b.

[0054] The first link 33 of the cam mechanism 31 rotates between a first position and a second position. That is, the first link 33 is in the first position when it abuts against the front end of the cam 30a, and in the second position when it enters between the two cams 30a, 30a, through the rotation of the rotating body 21.

[0055] The linkage mechanism 32 has a first link 33 and a second link 35 that can rotate about an axis 35a.

[0056] The second link 35 is L-shaped. At one end of the second link 35, the first link 33 is coupled by engagement of a pin with a long hole. In addition, the other end of the second link 35 is pivotally supported by a fixed shaft 35a. Further, the other end of the second link 35 is coupled to a race switching member RSM which is rotatably provided on the track disk 100A with the shaft 35a as a center by a torsion spring 36. That is, as shown in Figure 9 FIG. 6, a T-shaped protrusion 37 is provided on the lower side of the race switching member RSM, the protrusion 37 enters an arc-shaped slit (not shown) formed in the upper wall of the track disk 100A, and extends to the inside of the track disk 100A. The race switching member RSM is coupled to the other end of the second link 35 by sandwiching the web portion of the T-shaped protrusion 37 with both ends 36a, 36a of the torsion spring 36. The second link 35 and the race switching member RSM act integrally by the torsion spring 36.

[0057]

[0058] Next, the operation of the track toy 100 will be described.

[0059] (When entering from the basic track 10)

[0060] As shown in Figure 1 FIG. 7, the vehicle toy 50 approaching the branch point BP from the basic track 10 abuts against the operation member CM. Then, as the vehicle toy 50 travels, the operation member CM rotates counterclockwise in plan view against the force of the torsion spring 19. At this time, since the rotating body 21 does not rotate, the race switching member RSM is not switched. In this case, as shown in Figure 1 FIG. 8, when the basic track 10 is connected to the track 12 by the race switching member RSM, the race switching member RSM maintains its state, the inner surface of the wheels on the left side of the vehicle toy 50 is in sliding contact with the race switching member RSM, and the vehicle toy 50 is guided to the track 12.

[0061] Further, as the vehicle toy 50 advances, the abutting position of the operation member CM shifts from the front of the vehicle toy 50 to the side surface Figure 2 ). However, during the period of abutting against the side surface of the vehicle toy 50, the operation member CM maintains the retracted state. At this time, since the rotating body 21 does not rotate, the race switching member RSM is not switched.

[0062] ​Furthermore, as the toy vehicle 50 moves forward, the operating component CM disengages from the side of the toy vehicle 50. Consequently, the operating component CM returns to its initial position under the force of the torsion spring 19. At this point, the toy vehicle 50 has passed the track guide section of the track switching component RSM. However, due to the return of the operating component CM, even if the rotating body 21 rotates and the track switching component RSM is switched via the connecting rods 33 and 35, it will not hinder the movement of the toy vehicle 50, and the toy vehicle 50 can be reliably guided to the track 12.

[0063] Even when the basic track 10 and track 11 are connected, the track switching component RSM can reliably guide the vehicle toy 50 to track 11. In this case, the outer surface of the left wheel of the vehicle toy 50 slides into contact with the track switching component RSM, and the vehicle toy 50 is guided to track 11.

[0064] (When entering from runways 11 and 12)

[0065] When the toy vehicle 50 enters the bifurcation point BP from runways 11 and 12, the following actions are performed. Here, it is assumed that the toy vehicle 50 enters the bifurcation point from a runway connected to the main runway 10, such as runway 12.

[0066] In this case, since the track switching component RSM does not obstruct the movement of the toy vehicle 50, the front of the toy vehicle 50 abuts against the operating component CM where it passes the track switching component RSM. As a result, the operating component CM overcomes the force of the torsion spring 19 and rotates clockwise when viewed from above. However, the rotating body 21 does not rotate, and the toy vehicle 50 passes directly through the operating component CM. Strictly speaking, the rotating body 21 rotates slightly, but returns to its pre-rotation position by abutting against the edge of the rotating body 21 by the anti-rotation component 25, which is exerted by the coil spring 26.

[0067] In contrast, the toy vehicle 50 was never connected to the track of the basic track 10, for example... Figure 3 When track 12 enters the bifurcation point BP, the wheels of the toy vehicle 50 come into contact with the track switching component RSM. In this situation, the wheels of the toy vehicle 50 slide into the track guide of the track switching component RSM, and the track switching component RSM rotates against the force of the torsion spring 36. Thus, the toy vehicle 50 can pass through the area of ​​the track switching component RSM. Afterwards, it collides with the operating component CM, and the toy vehicle 50 passes directly through the area of ​​the operating component CM.

[0068] In addition, if the toy vehicle 50 enters the bifurcation point BP on the runway 11 that has never been connected to the basic runway 10, the runway switching component RSM will also activate, and the toy vehicle 50 will be able to pass through the bifurcation point BP.

[0069] Effects of Embodiments

[0070] Next, the main effects of the track toy 100 of the embodiment will be described.

[0071] First, since the runway switching member RSM and the operation member CM end the abutment against the side surface of the vehicle toy 50 of the operation member CM after the runway guidance by the runway switching member RSM, and then, the runway switching member RSM is switched, even in the case where the vehicle toy 50 is long, the vehicle toy 50 can be reliably guided to the prescribed runway. Second, in the case where the vehicle toy 50 enters the branch point BP from the runway 12, even in the case where the runway switching member RSM blocks the runway of the vehicle toy 50, since the runway switching member RSM retreats by the sliding contact of the vehicle toy 50, the vehicle toy 50 can pass through the place of the runway switching member RSM.

[0072] Variations

[0073] In the above embodiment, the case of the branch point BP where one basic runway is divided into three runways is described, but it can also be applied to the case of the branch point BP where one basic runway is divided into three runways.

[0074] In this case, for example, instead of the convex strip 30a, the cam is made in the shape shown in the drawing, and the first link 33 abuts at three points Pl, P2, P3 every time the rotating body 21 rotates a prescribed angle, whereby the runway switching member RSM can be switched to three positions. Figure 10

[0075] Further, in the above embodiment, the runway switching member RSM is operated by the operation of the operation member CM, but after the vehicle toy 50 passes, various mechanisms or switches are operated by the returning power of the operation member CM, the electronic bulletin board of the station can be rotated, the signal light of the station can be turned off, the alarm can be made to ring the "ding-dong" bell, the vehicle toy stopped at the adjacent platform can be made to depart, the dolls on the station can be made to act to perform the performance of walking on the platform, or the vehicle toy in front of the station can be made to stop or depart, the crossbar of the intersection can be made to fall down at the appropriate timing, and the like.

[0076] Specifically, every time the vehicle toy 50 passes, the drum-type sign on which the destination display is performed can be made to rotate in one direction intermittently to change the destination display using the intermittent motion mechanism 20A. The positions of the station staff and the passengers on the platform can be changed using the intermittent motion mechanism 20A and the cam mechanism 31 every time the vehicle toy 50 passes.
