Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a model railway vehicle, and more particularly, to an improvement in a model railway vehicle having a front wheel at the head, such as a model railway steam locomotive.
[0002]
[Prior art]
Actual steam and electric locomotives use large diameter wheels. If such a large-diameter driving wheel is present at the top of the locomotive, the rail climbs on the driving wheel when the locomotive passes through the curved section of the track. It is already well known that wheels with small diameters are installed at the very top so that they can be used.
[0003]
In this way, the small-diameter wheel located at the foremost part of the locomotive is called “leading wheel” or “leading wheel” in the sense of leading the driving wheel and rotatably supports a pair of left and right front wheels. The cart is called the “destination cart”. Such a front wheel is not only for directing the top of the locomotive in the curve direction when the locomotive passes through the curved portion, but also for appropriately distributing the total locomotive weight.
[0004]
By the way, in an actual steam locomotive, a part called a cylindrical buttocks, which is a part of the piston cylinder device, is provided on the outer sides of the left and right front wheels so as to protrude from the tip of the cylinder body. . This cylindrical bottom rod is a cylindrical body in which a part of a piston rod connected to a piston reciprocating in a cylinder body enters and exits.
[0005]
Moreover, in an actual electric locomotive, the step base may be provided so as to be located outside the left and right front wheels. For example, when stepping on an electric locomotive from a passenger car or a freight car, a worker with a flag temporarily rides on the step base and sends a signal to the driver. Is used.
[0006]
[Problems to be solved by the invention]
By the way, in order to accurately resemble the shape of an actual steam locomotive or electric locomotive as described above even in model railway cars, especially model steam locomotives and model electric locomotives, the left and right front wheels Are provided so as to be located on the outer sides.
[0007]
Of course, in model steam locomotives and model electric locomotives, the butt stick and the step stand are merely decorative items for giving the feeling that they are the same as the actual vehicle. However, in conventional model steam locomotives and model electric locomotives in which such ornaments are arranged close to the outer sides of the left and right front wheels, they face outward when passing through the curved part of the rail. There is a problem that the front wheel (the front wheel located inside the curved portion) contacts the ornament and derails.
[0008]
For this reason, in conventional model steam locomotives and model electric locomotives, decorative items such as buttocks and step bases located on the outer sides of the left and right front wheels can be attached and detached from the mounting portion. When running a locomotive or model electric locomotive on the rails, the ornaments were removed.
[0009]
However, when actually driving a model steam locomotive or model electric locomotive, it is very annoying to remove the ornaments located next to the front wheels and to reattach the ornaments after the run. Has a problem that it is easy to lose because it is a relatively small part.
[0010]
The purpose of this invention. It was made in order to solve such a conventional problem, and is equipped with a front wheel and an ornament such as a butt stick or a step stand is located on the outer side thereof, such as a model steam locomotive or a model electric locomotive. In the model railway vehicle of the present invention, when the model train is run on the rail without removing such ornaments, the model train vehicle that does not contact the ornaments even if the front wheel changes its direction at the curved portion. It is to provide.
[0011]
[Means for Solving the Problems]
The present invention provides a model railway vehicle having a pair of left and right front wheels at the top and positioning vehicle components adjacent to the outside of each of the front wheels. The model model vehicle is supported so as to be movable outward in the width direction of the model train vehicle, and when the model model vehicle passes the curved portion, this point is synchronized with the angle change of the left or right front wheel that changes the direction to the outside direction. Synchronous movement means for moving the vehicle component adjacent to the wheel slightly outward and returning the vehicle to its original position when the front wheel returns in the straight traveling direction is provided.
[0012]
Further, in the railway model vehicle of the present invention, a pair of left and right front wheels are rotatably supported by a front carriage, and the front carriage is composed of a rotating plate that is pivotally attached at one end to the chassis of the railway model car. The synchronous movement means includes an actuating element provided on the rotating plate and a contact element that is attached to and contacts the actuating element to interlock each vehicle component.
[0013]
Furthermore, in the model railway vehicle of the present invention, the synchronous movement means includes an interlocking portion that interlocks the movement of each contact with the corresponding vehicle component, and the interlocking portion is a connecting rod. The synchronous movement means further includes a spring that constantly applies a displacement force that directs the left and right vehicle components toward the center in the width direction of the model train vehicle, and when the front wheel changes its direction from the straight traveling direction, The actuating element that moves on a virtual arc line with the rotation of the actuator moves either the left or right vehicle component outward through the contact and the connecting rod against the biasing force of the spring. .
[0014]
Furthermore, in the model railway vehicle according to the present invention, the initial position of the vehicle component when the front wheel is directed straight ahead is moved downward by the biasing force from the spring received by each vehicle component on the starter. The contact surface of the activator with the contact to be applied with the initial load is a downward component force generating surface.
[0015]
In that case, the activator is preferably formed of a triangular member. At this time, the triangular member is erected and fixed by placing one side of the triangular member on the rotating plate, and the other two sides of the triangular member, that is, the two inclined surfaces form a downward component force generating surface.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the railway model vehicle of the present invention will be described in more detail with respect to an embodiment shown in the drawings. FIG. 1 is a side view schematically showing a wheel portion 10 as a main part of a model steam locomotive (hereinafter simply referred to as a locomotive) as an embodiment of a model railway vehicle of the present invention. It is the bottom view which looked at the wheel part 10 of the model steam locomotive shown in FIG.
[0017]
A wheel portion 10 of a locomotive according to this embodiment includes a pair of left and right front wheels 11 and 11 at the top, and has a large diameter behind each front wheel 11 (rightward as viewed in FIGS. 1 and 2). A driving wheel 12 is provided. On the outer sides of the left and right front wheels 11, a decorative part 13 in the shape of a butt stick, which is a vehicle component, is positioned adjacent to the front wheel 11.
[0018]
Each of these decorative parts 13 is composed of a rod-like portion 13a that extends in the longitudinal direction of the locomotive as a whole and a cylindrical portion 13b having a large diameter that is integrally formed on the rear side thereof. For convenience, the cylindrical portion 13b is referred to as a proximal end portion of the decorative part 13, and an end surface on the rear side of the cylindrical portion 13b is referred to as a proximal end surface.
[0019]
Each of these decorative parts 13 is supported so as to be independently movable from an initial position, which will be described later, to the outer side in the width direction of the locomotive. Specifically, as shown in FIG. 1 and FIG. 2 and FIG. 3 showing an enlarged top portion of the wheel portion 10, the base end surface of each decorative part 13 in the shape of a butt stick is a chassis of a model steam locomotive. The cylinder-shaped portion 14 is formed so as to be in sliding contact with the front end surface of the cylinder-shaped portion 14, and one end of the connecting rod 15 is connected to the inner side of the base end portion (inner side in the vehicle width direction).
[0020]
The connecting rod 15 connected to the base end of each decorative part 13 extends in the width direction of the locomotive, and a contact 16 is provided at the other end. Specifically, the contact 16 has a thin plate shape, and an upper portion of one surface thereof is connected to the other end surface of the connecting rod 15 so as to hang downward.
[0021]
Although it has been described that one end of the connecting rod 15 is connected to the base end of the decorative part 13 and the contact 16 is provided at the other end, these three components 13, 15, 16 are actually All are integrally formed as one resin molded product. The resin molded product in which the decorative part 13, the connecting rod 15, and the contact 16 are formed as an integrated body is referred to as a “decorative integrated part” for convenience of explanation.
[0022]
Among the decorative integrated parts, the connecting rod 15 and the contact 16 are also constituent elements of a synchronous moving means for moving the decorative part 13 in synchronization with the change of the direction of the front wheel 11. When two decorative integrated parts are arranged on the bottom surface of the chassis head, each contact 16 is opposed to the locomotive at the center of the bottom of the locomotive with a slight gap. A part of the other end surface of the connecting rod 15 contacts both side surfaces of the stopper 17 that hangs downward.
[0023]
This position is the setting position of the decorative integrated part. When each decorative integrated part is arranged at this set position on the lower surface of the chassis head, the acting force that each moves toward the inner side in the width direction of the locomotive is urged by one coil spring 18. . The coil spring 18 is attached by hooking hooks at the ends of the coil springs 18 to locking pieces 19 protruding from the other end of the connecting rods 15 to the rear of the locomotive.
[0024]
As a result, the coil spring 18 pulls the two decorative integrated parts toward each other, and as a result, each contact 16 provided at the other end of each connection rod 15 faces each other at a very close position and each connection. Positioning to a set position where a part of the other end surface of the rod 15 contacts both side surfaces of the stopper 17 is achieved.
[0025]
When the decorative integrated parts arranged on the left and right sides of the locomotive are arranged so as to pull each other by the coil spring 18 and are in the set position described above, the position of the decorative part 13 in the shape of the bottom bar is the position of the cylinder-shaped portion 14. It is slightly closer to the inner side in the width direction of the locomotive than a predetermined position on the front end face.
[0026]
When these decorative integrated parts are disposed on the bottom surface of the chassis head, as shown in FIG. 4, they are partially covered by a lower plate or cover plate 20 attached to the bottom surface of the chassis head. Without falling, it can move in the lateral direction (the width direction of the locomotive) within the space formed between the cover plate 20 and the bottom surface of the chassis head. Therefore, the cover plate 20 is a fall prevention plate for the decorative integrated part and also a lateral movement guide plate.
[0027]
By the way, a pair of left and right front wheels 11 that are arranged at the front of the chassis and that constitute the wheel portion 10 are axles that are rotatably supported at one end of a plate-like rotation plate 21 that extends in the front-rear direction of the locomotive. (Not shown) at both ends. That is, the rotating plate 21 is configured as a leading carriage for the leading wheel 11. As is apparent from FIG. 3, the other end of the rotating plate 21 passes directly under the middle part of the contact 16 and coil spring 18 of the two decorative integrated parts, and is located at the rear side of the chassis head. It is pivotally attached to the bottom.
[0028]
An actuating element 22 is fixed to a portion of the upper surface of the rotating plate 21 that is located directly below the interval between the two contact elements 16 that constitute each decorative integrated part. As shown in FIG. 5, the actuator 22 is an isosceles triangular plate-like body, with the apex angle portion facing up and two inclined surfaces that are isosceles portions facing both sides of the locomotive in the width direction. It is arrange | positioned on 21 and the base is integrally molded by the rotation board 21, or is fixed by well-known joining techniques, such as welding and adhesion | attachment.
[0029]
The actuating element 22 composed of a plate-like body of isosceles triangles must have a base whose length is larger than the width of the opposing spacing portions of the two contactors 16 in the two decorative integrated parts at the set position described above. . This is because an initial load is applied to the front wheel 11 to be described later. That is, as shown in FIG. 5, when the rotating plate 21 is assembled to the chassis head portion with the front wheel 11 facing in the straight direction, the isosceles triangular starter 22 fixed on the rotating plate 21. The apex angle portion is brought close to the bottom surface of the chassis so as to enter the facing interval portion of the two contactors 16.
[0030]
When the apex angle portion of the activator 22 starts to enter the facing interval between the two contactors 16, the lower end edge of each contactor 16 comes into contact with each oblique side that is an isosceles portion of the activator 22, and further, at a predetermined position (rotation). When the other end of the moving plate 21 is brought close to the bottom of the chassis to the extent that the other end of the moving plate 21 can be pivotally attached to the chassis, the actuator 22 further enters the opposing space of the contact 16 and pushes the two contacts 16 in the width direction of the locomotive. spread.
[0031]
This state will be described in more detail with reference to FIG. 5. FIG. 5 shows a state in which the decorative integrated part is in the set position. The two contactors 16 in the set position and the rotating plate 21 are shown. Is drawn to overlap the activator 22 that is positioned when is mounted at a predetermined position. Therefore, in the actual state, the decorative integrated component is only on the outer side in the width direction of the locomotive against the urging force of the coil spring 18 at the lower end edge shown where the lower end edge of each contact 16 overlaps the actuating element 22. Will be pushed out.
[0032]
This state is the initial position of the decorative integrated part and the starter 22. Therefore, the urging force of the coil spring 18 acts on the isosceles portion of the activator 22, that is, each inclined surface in a direction perpendicular to the inclined surface, from the lower end edge of the contact 16, and its downward component force is applied to the rotating plate 21. As a result, it acts as a pressing force against the rail against the front wheel 11 supported at one end thereof.
[0033]
That is, such an acting force becomes an initial load on the front wheel 11 when the front wheel 11 is directed straight, and prevents the front wheel 11 from being lifted when the locomotive is traveling straight, thereby improving running stability. Will give.
[0034]
Next, in the model steam locomotive of the above-described embodiment, the operation of the mechanism for avoiding contact by moving the decorative part outward when the direction of the front wheel changes will be described. When this model steam locomotive passes through the curved portion, the front wheel 11 changes its direction along the rail as shown in FIG.
[0035]
When the front wheel 11 starts to change direction from the straight direction to either the left or right direction, the rotating plate 21 rotates about the pivoting portion, and the activator 22 on the rotating plate 21 rotates accordingly. It moves on the virtual circular arc line (the center point is the pivot plate other end pivoting portion) toward the moving plate one end side deflection direction. As a result, as shown in FIG. 7, the activator 22 pushes the contact 16 on the side to which the actuator 22 moves in the lateral direction.
[0036]
Then, the decorative part 13 moves sideways against the urging force of the coil spring 18 by an amount corresponding to the amount of movement of the actuating element 22 through the connecting rod 15 connected to the contact 16, and as a result, the outer side Therefore, contact with the front wheel 11 can be avoided.
[0037]
When one of the decorative integrated parts is moved outward in the width direction of the locomotive by the movement of the starter 22 fixed to the rotating plate 21, the contact 16 is separated from the starter 22 for the other decorative integrated part and Although it moves to the inner side in the width direction of the locomotive by the pulling force of the coil spring 18, since the other end of the connecting rod 15 contacts the stopper 17 at the set position described above, no further inward movement occurs.
[0038]
In this manner, the vehicle component adjacent to the front wheel 11, that is, the decorative part 13 is slightly moved outward in synchronization with the change in the angle of the left or right front wheel 11 that changes its direction outward. In addition, when the front wheel 11 returns to the straight traveling direction, the vehicle component can be automatically returned to the original initial position.
[0039]
Further, in the model steam locomotive of this embodiment, the straight direction is achieved by the above-described mechanism for avoiding the contact between the front wheel 11 facing outward and the decorative part 13 when the front wheel 11 travels the curved portion. Since the initial load is applied to the front wheel 11 that faces the front, the running stability of the front wheel 11 can be obtained at the same time.
[0040]
In the above-described embodiment, the model steam locomotive has been described as an example. However, the present invention is not limited to this model steam locomotive, and includes a front wheel such as a model electric locomotive or a model diesel locomotive. Needless to say, the present invention can be similarly applied to various types of model railway vehicles provided with various components on the side.
[0041]
【The invention's effect】
As described above, according to the present invention, a railroad model such as a model steam locomotive or a model electric locomotive having a front wheel and a decorative part such as a buttocks or a step base on the outer side thereof is located. In a vehicle, when the model railway vehicle is run on the rail without removing the decorative part, the front wheel does not come into contact with the decorative part even if the front wheel changes its direction at the curved portion. It is possible to run on the rail while attaching decorative parts such as a step base.
