Description

  The present invention relates to a railroad model rail cleaning device and a railroad model railroad cleaning vehicle.

  Conventionally, a railway model has been enjoyed as a hobby. In a railway model, a vehicle (this is referred to as a model vehicle for the sake of convenience) that has been elaborately manufactured at a certain scale imitating an actual railway vehicle is referred to as a model vehicle rail (this is referred to as a model rail for convenience). Run on. The model vehicle is generally driven by electric power. Electric power is supplied from an external power source via a model rail.

  If dust adheres to the surface of the model rail or becomes dirty, various problems may occur. For example, the frictional resistance between the model vehicle and the model rail may change, and the model vehicle may not travel as expected. In addition, the electrical resistance between the model rail and the wheel may change due to dirt or sparks on the model rail, and it may be difficult to supply sufficient power.

  For example, Patent Documents 1 and 2 disclose measures for cleaning the model rail. Patent Document 1 discloses a device in which a cleaning pad is detachably attached to a foundation attached to a handle. Patent Document 2 discloses a cleaning vehicle equipped with a dust collection fan or a polishing head.

  In the device disclosed in Patent Document 1, it is necessary to perform a cleaning operation by grasping this device. When the extension path of the model rail is long, it is complicated to perform the cleaning operation over the entire path. In addition, there is a problem that it is difficult to clean a portion where a hand such as a tunnel cannot be reached.

  In the one disclosed in Patent Document 2, a horizontal torque is generated because the polishing head directly connected to the motor is rotated. In order to prevent deviation (derailment) from the rail due to this torque, the weight increases because a relatively large weight is mounted, and it is necessary to connect a powerful power vehicle that pulls or propels this cleaning vehicle. Furthermore, since the power vehicle is connected, the rail cleaning to the vicinity of the end must change the direction of the train.

  The present invention has been made in view of the above circumstances, and does not require a complicated manual cleaning operation, and is a rail model rail cleaning device that operates with a small torque and a lightweight and self-propelled rail model for rail cleaning. Providing a vehicle is an exemplary problem.

  In order to solve the above problems, a railroad model rail cleaning device as an exemplary aspect of the present invention is a railroad model rail cleaning device provided in a railroad model vehicle, and is in contact with the surface of the railroad rail for the railroad model. A mounting member for holding a polishing film for cleaning the surface of the rail, a holding member for rotatably holding the mounting member around an orthogonal axis orthogonal to a plane including the surface of the rail, and a surface of the rail An eccentric mechanism capable of eccentrically moving the mounting member in a plane including

  Further objects and other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  According to the present invention, it is possible to provide a rail model rail cleaning device that operates with a small torque and does not require a complicated manual cleaning operation, and a rail cleaning model rail vehicle that is light and self-propelled.

It is a general view of a railway model of an embodiment. It is a schematic block diagram of the cleaning apparatus of embodiment. It is the enlarged view which looked at the bottom part of the model vehicle from the bottom. It is the whole cleaning device perspective view showing the appearance of an attachment member.

<Configuration of cleaning device>
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an overall view of a railway model S according to the embodiment. In the embodiment, a model vehicle 1 will be described as a typical example. A rail for a model train (model rail) on which the model vehicle 1 travels is referred to as a model rail 2.

  A model vehicle 1 equipped with a railroad model rail cleaning device 3 (see FIG. 2) according to this embodiment will be described. In the present embodiment, as shown in FIG. 1, the traveling direction of the model vehicle 1 is the front-rear direction, the direction in which the model vehicle 1 is viewed from the model rail 2 is the upward direction, and the opposite direction is the downward direction. The left-right direction is defined when the model vehicle 1 is viewed from the front, and the left-right direction is sometimes referred to as the width direction.

  A model vehicle (rail cleaning model railcar) 1 has a plurality of wheels 4. The wheel 4 rolls on the surface of the model rail 2. A cleaning device 3 is provided inside the model vehicle 1. FIG. 2 is a schematic configuration diagram of the cleaning device 3. FIG. 2 shows the model vehicle 1 as viewed from the front, and shows the inside of the model vehicle 1 for ease of explanation. FIG. 3 is an enlarged view of the bottom of the model vehicle 1 as viewed from below.

  The cleaning device 3 includes a motor 5, an eccentric member 6, a bearing (holding member) 7, and an attachment member 8. The motor 5 can rotate the motor shaft (orthogonal shaft) 5a by supplying electric power, and the motor shaft 5a is disposed so as to extend downward along the vertical direction. That is, the motor shaft 5 a extends along a direction orthogonal to the plane P including the surfaces of the two model rails 2. The motor 5 is disposed in the model vehicle 1 so that the cleaning surface 8c contacts the surface of the model rail 2 by its own weight. For example, as shown in FIG. 2, the motor 5 may pass through the floor plate 10, and the motor 5 may be held on the floor plate 10 so as to be movable up and down.

  An eccentric member 6 is attached to the motor shaft 5a. The attachment of the eccentric member 6 may be fixed by various measures such as press fitting, adhesion, and heat caulking. The eccentric member 6 has a generally donut shape having an outer periphery and a center hole, and the center hole is offset (eccentric) by a certain amount with respect to the center of the outer periphery. When the motor shaft 5a rotates, the outer periphery of the eccentric member 6 rotates eccentrically, and the eccentric operation becomes the power of the eccentric movement of the mounting member 8 described later. The motor 5 and the eccentric member 6 constitute an eccentric mechanism 9. That is, the eccentric mechanism 9 causes the mounting member 8 to eccentrically move in the circumferential direction in the plane P in all directions including the width direction and the front-rear direction of the model rail 2.

  The bearing 7 rotatably holds the mounting member 8 around the motor shaft 5a orthogonal to the plane P. The eccentric member 6 is fitted into the inner ring of the bearing 7, and the outer ring of the bearing 7 is fitted into the through hole 8 a of the mounting member 8. When the motor shaft 5a rotates, the mounting member 8 vibrates eccentrically by the action of the eccentric member 6. At this time, since the attachment member 8 is freely rotatable with respect to the motor shaft 5a by the bearing 7, the attachment member 8 itself does not rotate in synchronization with the motor shaft 5a.

  As shown in FIG. 4, the attachment member 8 has a through hole 8a and a disk portion 8b. The through hole 8a is formed near the center of the circle, and the bearing 7 is fitted into the through hole 8a. The bearing 7 is fixed in the through hole 8a by a method such as press fitting, adhesion, or heat caulking.

  The through hole 8a and the disk portion 8b are formed concentrically. The lower surface (bottom surface) of the disk portion 8b is a cleaning surface 8c. The cleaning surface 8 c has a function of holding the polishing film 8 d and cleaning the surface of the model rail 2 when the polishing film 8 d comes into contact with the surface of the model rail 2.

  The polishing film 8d preferably has a fine particle size of 1 μm or less. The cleaning surface 8c moves in an irregular orbit. A small motor with a small torque can be applied to the motor 5. There is little increase in running resistance of the model vehicle 1 due to polishing. The risk that the model vehicle 1 is derailed with cleaning is reduced, and the weight of the model vehicle 1 can be reduced. There is no need to mount a weight for increasing the weight on the model vehicle 1.

<Operation of cleaning device>
When the model rail 2 is cleaned using the model vehicle 1, when the motor shaft 5 a starts to rotate, the mounting member 8 is not allowed due to the action of the eccentric member 6 and the frictional resistance between the polishing film 8 d and the model rail 2. Vibrates regularly. The attachment member 8 rotates asynchronously and slowly around the motor shaft 5a. A combined trajectory T obtained by combining the eccentric motion and the rotational motion by the eccentric member 6 is as shown in FIG. A synthetic trajectory T shown in FIG. 3 shows a movement trajectory of one arbitrary point on the polishing film 8d due to the rotation of the motor 5. When the attachment member 8 moves like the synthetic locus T, only a specific portion of the polishing film 8d is used for cleaning, and most of the polishing film 8d is used for cleaning all over. .

  The model vehicle 1 is run on the model rail 2. The model vehicle 1 travels while the polishing film 8d is in contact with the surface of the model rail 2 with a constant contact pressure by the weight of the motor 5. By using the small and light motor 5, the contact pressure between the polishing film 8d and the surface of the model rail 2 can be reduced, and cleaning with a light contact pressure is possible.

  Since the surface of the model rail 2 is cleaned while the model vehicle 1 is traveling, the model rail 2 in a long distance or the model rail 2 in the tunnel can be used without complicated manual cleaning. Easy cleaning.

  By the rotation of the motor shaft 5a, the polishing film 8d moves eccentrically (vibrates) both in the width direction (left-right direction) and in the front-rear direction (that is, in the plane P). Under the influence of the change in frictional resistance between the surface of the model rail 2 and the polishing film 8d, the polishing film 8d rotates around the motor shaft 5a while oscillating, and moves along a track such as the combined track T. The model rail 2 can be cleaned while using most of the polishing film 8d uniformly and efficiently.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these, A various deformation | transformation and change are possible within the range of the summary. For example, the present invention includes the following gist.
