Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to expansion and contraction and improvement of a swinging mechanism in a closely coupled coupler for a railroad model.

[Prior Art] There has been no expansion and contraction or swinging mechanism in a conventional tightly coupled coupler (vehicle coupler) for a railroad model.

This is a conventional model model tightly-coupled coupler, which is simply the model of the actual vehicle (actual vehicle) densely-coupled coupler as it is, and is the coupler's original function of vehicle coupling.
Due to the inability to release.

However, the expansion and contraction and swinging mechanism in a general coupler is provided with a long guide groove 42 in a long swinging body 41 having a coupler 40 at the tip as shown in FIG. It is fitted to a fulcrum 43 provided on the dolly so that it can be moved back and forth. Furthermore, a guide pin 44 is provided on the neck portion of the swing body 41, and the guide pin 44 is a curved guide groove provided on the floor plate of the vehicle.
There is one that fits into the 45 so that it can swing freely to the left and right, and that it also comes with a spring that always returns the swinging body to the vehicle center.

[Problems to be solved by the invention] The close-coupled coupler in an actual vehicle is mainly used for connecting trains, and its structure is that the coupler is provided with a protrusion and a concave fitting portion. It is a method of connecting by inserting a pin into a small hole provided on the side surface of the protrusion after it is fitted in the concave fitting portion of the mating coupler, and the shape and structure of the coupler itself is complicated, and the couplers are It was extremely difficult to adopt it as a model railroad because pins were used to connect the two.

From such a technical background, in the conventional railway model, the close-coupler was attached as a decorative item only for the leading car in order to make it more realistic.

Further, since the expansion and contraction and swinging mechanism of the conventional general coupler uses two guide grooves, the degree of expansion and contraction is small. Therefore, not only the couplers during running often come off, but also the vehicle derails. There were many problems.

In addition, the conventional one requires a spring for always returning the swing body to the vehicle center, and has a problem that the structure is complicated and the assembly is troublesome.

Also, the conventional expansion and contraction and swinging mechanism has a structure in which the mechanism itself has to be incorporated into the trolley, so it is not possible to assemble it alone, and not only is it time-consuming to assemble, but it is also far from the shape and structure of the actual vehicle. Therefore, in the field of railway models, which attaches importance to realistic models, improvements have been desired.

For this reason, in order to bring the model railcar closer to the actual car and to enhance the realism, the close-coupled coupler can be connected and released not only for decoration but also the coupler can be expanded and contracted and swung freely. Therefore, there has been a strong demand for development of expansion and contraction and swinging mechanism in a densely coupled coupler for railway model, which can exhibit the original function of the coupler.

Also, the degree of expansion and contraction of the coupler and the degree of swinging are large, not only does the coupler not come off while the vehicle is running,
The train does not derail, the structure is not complicated, it can be assembled independently without incorporating it into the trolley, the number of assembly steps is simple, and the close-coupled model coupler for railway model similar to the shape and structure of the actual car There has been a strong demand for the expansion and contraction and the development of a swinging mechanism.

[Outline of the Invention] The present invention has been made in order to meet the above demands,
The swing mechanism is swingably engaged to the left and right with the extension mechanism, and the extension mechanism is attached to the mounting base provided on the floor plate of the vehicle so that it can move back and forth to increase the degree of extension and swing of the coupler. An object of the present invention is to provide an expansion / contraction mechanism and a swinging mechanism in a tightly-coupled model railroad model coupler that is similar in structure and structure to the actual vehicle, because the couplers do not come off during vehicle running and the structure and assembly are simple. .

The coupler body 1 is integrally connected to a swing mechanism 8 via a guide body 7.

At the lower part of the coupler body 1, there is provided a vehicle connecting / releasing connecting part 4 similar to the shape of a relay (not shown) provided at the lower part of the close-coupled coupler of an actual vehicle. The connecting portion 4 is made of highly elastic nylon plastic or the like.

As shown in FIG. 3, a hook-shaped engaging portion 5 is formed on the connecting portion 4, and the engaging portion 5 is attached to the engaging portion 5 of the connecting portion 4 of the mating coupler during connection. By abutting and pressing each other, the two can be locked with each other, and the coupler body 1 can be connected freely.

The front surface of the connecting portion 4 is formed in a substantially isosceles triangular shape in cross section, and the upper surface and the lower surface thereof are tapered. The upper and lower tapered portions 6, 6 slide on each other to easily enter the engaging portion 5 of the other party, and smoothly engage and engage with each other.

At this time, since the taper portions 6, 6 are formed on both the upper and lower surfaces, they can be slid and inserted from any of the upper and lower directions at the time of connection, and the connection work can be performed reliably and easily.

5 can be easily separated. Further, at the time of this release, there is no possibility that the locking portions 5, 5 will be damaged.

The connecting portion 4 is integrally connected to the swing mechanism 8 via a plate-shaped guide body 9.

Since the connecting portion 4 is guided by the plate-shaped guide body 9, the connecting portion 4 can be moved in the vertical direction, and the engaging portions 5 and 5 can be connected during connection.
Since there is no need for positioning, the locking work becomes extremely easy.

In FIG. 3, the swing mechanism 8 includes a pair of engaging portions 10a, 1
0b, a pair of sliding portions 11a, 11b and a pair of locking portions 12a, 12b, the pair of engaging portions 10a, 10b, the expansion and contraction mechanism
The pair of engaging projections 14a and 14b provided on the inner surface of 13 are freely engageable.

The engaging portions 10a, 10b and the engaging protrusions 14a, 14b are loosely fitted while maintaining a play as shown in FIG. 14, and when the coupler body 1 is swung, as shown in FIG. When the swing mechanism 8 moves to the left or right, one of the engaging portions 10
When a moves, it abuts and engages with one of the engaging protrusions 14a, and at the same time, the other engaging portion 10b separates from the other engaging protrusion 14b.

The swing mechanism 8 rotates about the engaging projection 14a as a fulcrum, and at the same time, the sliding portion 11b slides while being guided by the engaging projection 14b, and the locking portion.
The rotation of the swing mechanism 8 is stopped when 12b is locked to the engaging protrusion 14b.

In this way, the swing mechanism 8 can perform the swing motion in either the left or right direction.

Next, as shown in FIGS. 4 to 7, the extension mechanism 13 is formed in a generally U-shaped frame shape, and the bottom plate 15 has engaging projections 14a, 1
4b is provided, and locking projections 17 are provided on the left and right side plates 16 in a protruding manner.

A cutout window 18 is provided on the lower outside of the side plate 16,
The left and right swinging range of the swinging mechanism 8 is widened. Therefore, even when the vehicle travels on a sharp curve or the like, there is no possibility that the couplers are released from each other or the vehicle derails.

In the figure, reference numeral 26 denotes a protrusion for facilitating pushing with a finger pad or the like when the expansion / contraction mechanism 13 is expanded / contracted, and 27 is a guide arrow that dies in the sliding direction, both of which are provided on the back surface of the bottom plate 15.

28 is a holding protrusion.

Two fitting holes 21 and 22 are provided at desired intervals, and a shallow guide groove 23 is provided between the fitting holes 21 and 22.

An accommodating portion 24 for accommodating the coupler body 1 in a non-connected state and a locking portion 25 for locking the guide body 7 of the coupler body 1 are provided outside the mounting base 20.

When the vehicle is not connected, the swinging motion of the coupler body 1 is not necessary, and therefore, the extension mechanism 13 is moved backward to fit the locking protrusion 17 into the fitting hole 22. In this state, a part of the coupler body 1 is accommodated in the accommodating portion 24, and at the same time, the guide body 7 is retained in the retaining portion 25 to prevent the coupler body 1 from swinging. FIG. 12 shows this state.

On the other hand, when the coupler body 1 is connected, when the expansion mechanism 13 is moved forward, the locking projection 17 is ejected from the fitting hole 22 and guided by the guide groove 23 to fit into the fitting hole 21. Stop. At this time, since the expansion / contraction mechanism 13 is formed in a U shape, it can be easily moved out of the fitting hole 22 by a spring action. FIG. 13 shows this state.

[Effects of the Invention] Therefore, according to the present invention, the degree of expansion and contraction and the degree of swinging of the close-coupled coupler can be increased, and not only the couplers will not come off while the vehicle is running, but also the vehicle will derail. In addition, the structure is simple, there is no need to assemble it in the trolley, it can be assembled independently, the number of assembly steps is simple, and the expansion and contraction and neck of the model model densely coupled coupler similar to the shape and structure of the actual car The swing mechanism can be obtained.

Further, according to the present invention, since the expansion and contraction and swinging mechanism can be obtained as described above, it is possible to connect and disconnect the vehicle not only for the purpose of decoration of the close-coupler type coupler but also to connect the original functions of the coupler. It is something that can be demonstrated, and the model train can be brought closer to the actual car and the realism can be enhanced.

For this reason, the present invention can be mounted not only on the leading vehicle as a decoration as in the past, but also as a coupler having a coupling / releasing function not only for the leading vehicle but also for all vehicles.
