DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting coupler structure for a railway model articulated vehicle, and more particularly, to a vehicle of a type in which a connecting vehicle and a bogie center coincide with each other in a railway model. The present invention relates to a structure of a coupling coupler in such an articulated train.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 6 and 7, a connecting coupler structure in a railway car of this type is composed of a frame 1 having four sides defined and a rectangular frame 1 inside. A cross-shaped member 2 integrally formed on the inner surface of each side, and the cross-shaped member 2 is formed in a column-shaped vertical shaft portion 2a and a horizontal direction provided substantially in the middle thereof. It was formed from the crosspiece portion 2b.

On the other hand, a trolley 3 having two wheels on each of the left and right sides.
Has a single shaft 3a rising from its upper center position, and this shaft 3a is connected to the vertical shaft portion 2 of the cross member 2 described above.
It is connected and fixed to the lower frame side of the rectangular frame 1 on the same central axis as that of FIG. Therefore, the truck 3
The shaft 3a extending from the shaft 3 and the vertical shaft portion 2a of the cross member 2 are formed as if they are a single shaft, and this shaft penetrates the frame 1 in the vertical direction to have such a structure.

[0004] A connecting arm 5 is fixed to an end of each articulated wheel 4. A circular concave portion, that is, a C-shaped engaging groove 5a is formed at the tip of the connecting arm 5. The connecting arms 5 fixed to both ends of the articulated vehicle 4 are provided with their upper and lower positions slightly shifted from each other. Each articulated wheel 4 to be connected is assembled in such a way that the ends with the connecting arms 5 whose mounting positions are shifted from one another face each other.

Accordingly, the connecting arm 5 provided at one end of the articulated wheel 4 is fitted and mounted on the vertical shaft portion 2a above the horizontal bar portion 2b from one opening surface of the frame 1, for example. A connecting arm 5 connected to the other end of the articulated wheel 4 facing the end of the articulated wheel 4 is connected to the lateral cross section 2 b
The lower shaft portion 2a is fitted and attached to the lower shaft portion 2a.

When the engaging groove 5a formed at the tip of each connecting arm 5 is fitted and mounted relatively to the vertical shaft portion 2a in the frame 1, the two can relatively rotate. The range is up to the position where the connecting arm 5 contacts the left and right frame sides of the frame 1. As a result, when the articulated vehicle 4 connected by such a conventional means travels on the rail 6, it can pass through a curve having a curvature calculated from this rotation range.

[0007]

However, in such a conventional articulated vehicle coupling coupler structure, if the coupling interval is reduced as in an actual vehicle, the model has a small radius of curvature at the curved portion of the rail, so that the vehicle has a small radius of curvature. Has come into contact with the frame 1 and cannot end up passing through the curve of the curvature.

[0008] Of course, if the length of the connecting arm 5 is increased to increase the distance between the ends of the articulated vehicle 4, such a curve can be passed, but this is very poor in appearance, and is a product as a model railway. There is a problem of lack of sex. It is assumed that the railway model is produced as close to the actual vehicle as possible.

Further, in the conventional coupling coupler structure for a railway model articulated vehicle, the coupling arm 5 substantially fitted and mounted on the shaft 3a rising from the bogie 3 is rotatable with respect to the shaft 3a. Since the connecting vehicle 4 is fixed to the connecting vehicle 4, there is no function of the connecting vehicle 4 moving away from the shaft 3a.

Therefore, when a railway model composed of a plurality of articulated vehicles 4 connected by such a conventional connecting coupler structure is run on rails, the body is easily shaken from side to side, and the vehicle running is unstable, and derailment is caused. There was even fear of. That is, it was considered that such a problem occurred because the connecting arm 5 did not have a function of expanding and contracting with respect to the connecting vehicle 4 or the connecting arm 5 with respect to the shaft 3a.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems. When the vehicle is traveling straight, and at a small deflection angle (relative angle of the vehicle when traveling on a curve), the end of the vehicle is connected. The rails are as small as possible so that the distance between them, that is, the connection distance, is close to the actual vehicle scale, but when passing through a curve, it is possible to assemble a railway that can guarantee smooth running without causing contact between the corners inside the curve at the end of the connecting vehicle facing the curve. An object of the present invention is to provide a connecting coupler structure of a model connecting vehicle.

[0012]

SUMMARY OF THE INVENTION The present invention relates to a connecting coupler structure for a railway model articulated vehicle, and adopts the following structure to achieve the above-mentioned object. That is, the connecting coupler structure of the articulated vehicle for a railway model according to the present invention includes a pair of horizontal connecting plates A and B formed or attached to opposing ends of a vehicle body constituting the articulated vehicle for a railway model, A recess formed on the connecting plate A, formed on the longitudinal center axis of the articulated vehicle, and two recesses formed on both sides of the longitudinal center axis.
A main engaging slot, a connecting pin holding groove formed continuously from a deepest portion of the main engaging slot of the connecting plate A, and extending obliquely outward from a longitudinal center axis of the articulated wheel; A connection shaft that rises from the center of the bogie that constitutes the articulated vehicle, that is rotatably inserted through the coupling plate B on the longitudinal axis of the articulated vehicle, and that projects onto the coupling plate B; Two connecting pins provided to stand substantially vertically on both sides of a longitudinal center axis of the articulated vehicle with the connecting shaft interposed therebetween; and a longitudinal center of the articulated vehicle more than the connecting shaft on the connecting plate B. A rotation regulating pin that is erected at the tip end on the axis, and an arrow-shaped groove formed continuously from the deepest part of the recess, and the connecting pin formed on both sides of the longitudinal center axis. The distance between the entrance of the holding groove and the connecting pin When the connecting vehicles are connected, the connecting plate is placed on the connecting plate B, the connecting shaft is placed in the recess, and the rotation regulating pin is further moved from the deepest portion. The connection pins are housed in the continuously formed barbed grooves, and the connection pins are respectively positioned at the connection pin holding groove entrances via the main engagement slots.

[0013] In the connecting coupler structure of the articulated train for a railway model of the present invention described above, the two main engaging slots include:
It can be further added to the feature that the main engagement slots are formed as arcs centered on the connection pin holding grooves formed continuously from the deepest portions of the main engagement slots facing each other.

In the connecting coupler structure of the articulated train for a railway model according to the present invention, the projection provided on the inner wall surface at the base of the arrow-shaped groove formed continuously from the deepest portion of the recess is provided. The fact that it serves as a stopper for the regulating pin can be further added to the feature.

[0015]

According to the connecting coupler structure of the articulated vehicle for a railway model of the present invention, each of the connecting plates A and B formed at the end of the opposing articulated vehicle has three pins provided on one of the connecting plates B. That is, the two connecting pins and the one rotation regulating pin are respectively connected to the connecting pin holding groove formed continuously from the deepest portion of the main engagement slot formed in the other connecting plate A and the deepest portion of the central recess. It is connected by being housed in the barbed groove formed.

In the train for articulated train in such a connected state, the two connecting pins are fixed at the deepest part of the main engaging slot, that is, at the entrance of the connecting pin holding groove during straight running,
It is impossible to get out through the main engagement slots formed at intervals smaller than the interval between these connecting pins, so that the connection of the connecting plates A and B is maintained, and the towing of the articulated vehicle is enabled. .

When the articulated vehicle travels on a curve with a small deflection angle, the connecting pin located inside the running curve enters the connecting pin holding groove by a slight rotation of the connecting plate A,
On the other hand, the outer connecting pin is still near the deepest part of the main engagement slot. Therefore, also in this case, the two connecting pins are engaged with the connecting pin holding groove and the main engaging slot, so that the connection between the connecting plates A and B is maintained, and the towing of the articulated vehicle is enabled. .

Next, when the articulated vehicle is traveling on a curve with a large swing angle, the relative swing of the connecting plate A with respect to the connecting plate B causes the connecting pin inside the running curve to be in the connecting pin holding groove. At the same time, the outer connecting pin moves on an arc centered on the inner connecting pin and out of the main engagement slot.

Accordingly, when the rotation regulating pin is also viewed with respect to the connecting plate A, the inner wall of the barbed groove is moved so as to move on an arc centered on the connecting pin fixed in the connecting pin holding groove located inside the curve. It comes into sliding contact with the protrusion on the base.

Accordingly, the connection pin on the inner side of the curve, which may be angularly moved from the connection pin holding groove to the main engagement slot, is moved in the main engagement slot direction by contact of the rotation restricting pin with the projection. The movement of the connecting pins A and B is restricted by the cooperative action of the two pins, so that the connection of the connecting plates A and B is maintained, and the towing of the articulated vehicle is performed even when traveling on a curve with a large swing angle. Is possible.

As described above, according to the connecting coupler structure of the articulated vehicle for a railway model of the present invention, the relative rotation center of the connecting plates A and B is not the connecting shaft rising from the bogie, but the connecting members on both sides, especially when traveling on a curve. Since the pin is a pin, the distance between the connecting pin serving as the center of rotation and the corner of the end of the articulated vehicle located inside the curve is reduced.

Therefore, even if the articulated vehicle approaches the actual vehicle scale, the vehicle can stably travel on a curve having a relatively small curvature. In addition, the connecting pins escape to the main engagement slots at appropriate times with respect to minute vibrations between the connected vehicles during traveling, so that the connected vehicles can swing to the left and right to some extent. High stability at the time can be obtained.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a connecting coupler structure of a train connecting vehicle according to the present invention. FIG. 1 shows a connecting coupler structure 10 of a railway model connecting vehicle according to an embodiment of the present invention. At both ends in the longitudinal direction of the chassis 11 forming one articulated vehicle,
As shown in FIGS. 2 and 3, horizontal connecting plates A and B having different structures are integrally formed.

Therefore, when connecting articulated vehicles,
These different types of connecting plates A and B are combined so as to face each other. As shown clearly in FIG. 2, the connecting plate A is formed with a recess 13 centered on the longitudinal center axis 12 of the chassis 11 of the articulated vehicle.
Two main engagement slots 14 on both sides of the recess 13 with the
Are formed.

At the deepest part of the main engaging slot 14 of the connecting plate A, the longitudinal center axis 1
2, a connecting pin holding groove 15 extending obliquely outward is formed. The connection pin holding groove 15 is formed such that a connection pin, which will be described later, is inserted into the slot 14 by about one slot, even if it is referred to as a “groove”. Also, connecting plate A
At the deepest part of the recess 13 formed from the tip at the center of the groove, a groove 16 having an arrowhead shape is formed continuously therefrom.

The recess 13 formed in the connecting plate A and the barbed groove 16 continuous therewith, and the main engaging slot 14 formed outside the recess 13 and the connecting pin holding groove 15 continuous therewith, Each is formed in a unique shape. Since these shapes are formed depending on the relative connection relationship with the various pins provided on the other connection plate B, they will be described again after the configuration of the connection plate B is described.

Therefore, the other connecting plate B is a substantially T-shaped plate when viewed from above as shown in FIG. 3, and its longitudinal center axis 17 coincides with the longitudinal center line of the chassis 11, and Wide-area surface portion 1 at the tip end of this connecting plate B
8, a connecting pin 19 is provided upright at an equidistant position with respect to a longitudinal central axis 17. The distance between the connecting pins 19 at this time is L as shown in FIG.

On a longitudinal central axis 17 which is an intermediate portion between the connecting pins 19, a connecting shaft rising from the center of the upper surface of a bogie (not shown) having a total of four wheels, two wheels on the left and right sides. Reference numeral 20 is provided through a hole (not shown) provided in the connecting plate B. The amount of protrusion of the connection shaft 20 above the connection plate B is not so large, and may be any height as long as it is equal to or greater than the thickness of the connection plate A described above.

The connection shaft 20 can be actually formed by a screw. In this case, a washer is attached to the screw, a through hole is inserted from the surface side of the connecting plate B, and a predetermined length of the screw is screwed into the screw hole on the upper surface of the boss formed at the center of the bogie directly below. Is done. As a result, the cart is connected to the connecting shaft 20
Through the connecting plate B.

A pin 21 similar to the above-described connecting pin 19 is mounted upright on the center axis 17 in front of the connecting shaft 20 inserted into the connecting plate B, that is, on the front end side of the connecting plate B. This pin 21 is referred to as a rotation restricting pin due to its function.

The connecting plates A, B thus constructed
Are moved along the longitudinal axis, and the connecting plate 19 slides on the connecting plate B so that the connecting pin 19, the connecting shaft 20, and the rotation regulating pin 21 are relatively connected to the connecting plate A.
Pin holding groove 15, recess 13 and barbed groove 16
It is connected by arranging in.

Here, the distance between the two connecting pin holding grooves 15 near the entrance is set to L which is the same as the distance between the connecting pins 19 as is apparent from FIG. As shown in FIG. 5, each of the main engagement slots 14 is connected around the connection pin 19 when the connection pin 19 on the opposite side with respect to the longitudinal center axis is located in the connection pin holding groove 15. The other connecting pin 19 is formed in an arc which is a moving trajectory of the other connecting pin 19 relative to the connecting plate A when the plate A is rotated or shaken.

Next, the recess 13 in which the connection shaft 20 is accommodated
2, the width of the inlet portion is substantially equal to the outer diameter of the connection shaft 20 and the width of the middle portion is formed larger than that as shown in FIG. I have. Then, the shape of the inner peripheral surface 13a near the entrance and the opposing interval relatively move when the connecting plate A swings to the maximum around the connecting pin 19 located in the connecting pin holding groove 15 as described above. The connecting shaft 20 is formed so as to contact the peripheral surface of the connecting shaft 20.

Continued inner peripheral surface 1 of recess 13 further in the depth direction
3b is also based on such a concept, and when the deflection angle of the connecting plate A relative to the connecting plate B gradually changes from zero to the maximum angle, the connecting shaft 20 of the connecting shaft 20 that moves relatively correspondingly. It is formed in a curved shape so as to be in sliding contact with the peripheral surface.

Further, both inner side surfaces 16b of the barbed groove 16 formed continuously in the depth of the recess 13 hold the connecting pin from the time when the swing angle of the connecting plate A relative to the connecting plate B is zero. Connecting plate A centering on connecting pin 19 located in groove 15
Is formed in an arc, which is the movement trajectory of the rotation regulating pin 21 relative to the connecting plate A until it swings to the maximum. That is, as shown in FIG. 5, when the deflection angle of the connecting plate A is zero, the rotation regulating pin 21 is located at the pointed end 16a, and is formed in an arc with the connecting pin 19 as the center of rotation.

When the connecting plate A has the maximum deflection angle, the portion where the rotation restricting pin 21 is located is the entrance of the barbed groove 16, and the connecting portion between the entrance and the recess 13 is the barbed groove 16. Protrusion 16c protruding inward as a base of
Are formed. Therefore, when the connecting plate A rotates to the maximum deflection angle, the rotation restricting pin 21 relatively moves in the direction of the base while slidingly contacting the arc-shaped inner side surface 16b of the arrowhead-shaped groove portion 16, abuts on the projection 16c, and connects. The further deflection of the plate A is regulated.

When connecting the connecting plates A and B configured as described above, the connecting plates A and B are connected to each longitudinal axis 1.
2 and 17 are brought close together, and the connecting plate A is placed on the connecting plate B so as to overlap. However, FIG.
As shown in the figure, when the rotation restricting pin 21 invades through the recess 13 to the vicinity of the base of the barbed groove 16, ie, near the inlet, and the connecting shaft 20 comes to a position passing through the inlet of the recess 13,
The two connection pins 19 abut against the outer frame portion 22 that defines the main engagement slot 14 and cannot enter as it is.

The reason for this is that, as described above, each of the main engaging slots 14 is centered on one connecting pin 19 located near the entrance of the connecting pin holding groove 15 formed continuously at the deepest portion. This is because the distance between the connecting pins 19 at the entrance is smaller than the distance L between the connecting pins 19 because the other connecting pins 19 are formed as arcs that are the movement locus of the other connecting pin 19.

In order to insert the two connecting pins 19 into the connecting pin holding grooves 15, as shown in FIG. 5, the connecting plates A and B are relatively close to each other at a certain angle. The distance between the connection pins 19 with respect to the two main engagement slots 14 of A is apparently narrow, so that the connection pins 19 can enter the main engagement slots 14 without any problem and enter the predetermined connection pin holding grooves 15. .

Next, the operation of the connecting coupler structure 10 of the articulated train according to this embodiment will be described. The coupling coupler structure 10 of the articulated vehicle for a railway model according to this embodiment 10
According to this, each of the connecting plates A and B formed at the end of the connecting vehicle facing each other has three pins provided on one of the connecting plates B, that is, two connecting pins 19 and one rotation regulating pin 2.
1 are housed in a connecting pin holding groove 15 continuous with the deepest portion of the main engaging slot 14 formed in the other connecting plate A and an arrowhead-shaped groove portion 16 continuous with the deepest portion of the central recess. .

In the train for articulated vehicle in such a connected state, two connecting pins 19 are connected to each other during straight running, as shown in FIG.
As shown in the figure, the connection pins 1 are fixed at the deepest portion of the main engagement slot 14, that is, at the entrance of the connection pin holding groove 15.
Main engagement slots 14 formed at intervals smaller than
, The connection of the connecting plates A and B is maintained, and the towing of the articulated vehicle becomes effective.

When the articulated vehicle travels on a curve at a small deflection angle, the relative deflection of the connecting plate A causes the connecting pin 19 on the inner side of the running curve to have the connecting pin holding groove as shown in FIG. 15 and the connecting plate A is ready to relatively rotate around the connecting pin 19.

This state occurs when the connecting plate A of this embodiment swings about three degrees with respect to the connecting plate B. Also in this case 2
Since the two connection pins 19 are engaged with the connection pin holding groove 15 and the main engagement slot 14, the connection between the connection plates A and B is maintained, and the connecting vehicle can be towed.

Next, when the connecting vehicle is traveling on a curve with a large swing angle, the connecting pin 19 inside the running curve is fixed in the connecting pin holding groove 15 as shown in FIG. A rotates about the connecting pin 19 with respect to the connecting plate B. As a result, the outer connecting pin 19 apparently moves on an arc centered on the inner connecting pin 19 (as a relative relationship when viewed from the connecting plate A), and thus the outer connecting pin 19 is located outside the curve. Engagement slot 14
Get out from inside.

Accordingly, the connecting shaft 20 is moved toward the inner peripheral surface 13a near the above-described entrance portion in the recess 13 so that the recess 1
3 is relatively moved while being in sliding contact with the inner peripheral surface of the inner peripheral surface 3, and is fixed in contact with the inner peripheral surface 13 a when the connecting plate A swings to the maximum. On the other hand, the rotation regulating pin 21 also moves the inner surface 16b of the barbed groove 16 so as to move on an arc centered on the connecting pin 19 fixed in the connecting pin holding groove 15 located inside the curve when the connecting plate A is viewed. Sliding contact with the base projection 16c
Abut.

As a result, the connecting pin holding groove 1 is angularly
The connection pin 19 on the inside of the curve, which may move out of the main engagement slot 14 to the main engagement slot 14, is
Is restricted from moving in the direction of the main engagement slot 14 by the contact of the projections 16c with the projections 16c. The connection of B is maintained, and the connected vehicle can be towed even when traveling on a curve with a large swing angle.

As described above, according to the connecting coupler structure of the railway model connecting vehicle, the relative rotation center of the connecting plates A and B is not the connecting shaft 20 rising from the bogie, especially when traveling on a curve, but the connecting pins on both sides thereof. 19, the distance from the connecting pin 19, which is the center of rotation, to the corner of the end of the articulated vehicle located inside the curve is reduced. Therefore, even if the articulated vehicle approaches the actual vehicle scale, the vehicle can stably travel on a curve having a relatively small curvature.

Further, when the connecting vehicles 19 run into each other, the connecting pins 19 enter the main engagement slots and the connecting pin holding grooves at a time to escape from the small vibration between the connecting vehicles, so that the connecting vehicles are prevented from swinging left and right. This is tolerable to some extent, so that high stability during running can be obtained.

[0049]

As described above, according to the connecting coupler structure of the articulated vehicle for a railway model of the present invention, the relative rotation center of the connecting plates A and B is not the connecting shaft rising from the bogie when traveling on a curve. Since the connecting pins are provided on both sides, the distance between the connecting pin serving as the center of rotation and the outer corner of the end of the connecting vehicle located inside the curve is reduced. Therefore, even if the articulated vehicle approaches the actual vehicle scale, the vehicle can stably travel on a curve having a relatively small curvature.

Furthermore, the connecting pins escape into the main engagement slots and the connecting pin holding grooves at appropriate times to escape from the slight vibration between the connected vehicles during running. As a result, high stability during running can be obtained.
