Abstract
Description
- The present invention relates to a dust collecting model railroad car for collecting dust on the model railroad track during its running.
- Many of model railroad are scale models that reproduce the shapes of real objects based on the scales such as 1/87 (HO-gauge). In addition, with the exception of some large sized models, an external power supplied generally through the rails on the model railroad track is used as motive power of model railroad cars.
- The model railroad track is constantly exposed to dust in typical environments without dust protection and dust trapped on the model railroad track may lead to model railroad car malfunctions. In addition, dust on the top surface of the rails can lead to poor current collection and sparking on the rails and wheel tread.
- As a measure for removing dust on a model railroad track, there are, for example, those disclosed in
patent literature 1 andnon patent literature 1.Patent literature 1 discloses a model railroad car in which a variety of cleaning heads, including centrifugal fan for dust collection, are mounted on a vertically mounted motor shaft.Non patent literature 1 also provides a model railroad car with a centrifugal fan fixed on a vertically oriented motor shaft. -

- However, the existing model railroad cars for dust collection have a structure which is uncomfortable as a model, such as a net or filter for dust collection is exposed to a part of the vehicle body. In addition, the length of the centrifugal blower in the direction of the rotation axis is restricted to less than the vehicle body height because it is installed in the vertical direction.
- Existing model railroad car for dust collection can only install the outlet of the centrifugal fan in one direction which faces the dust collection chamber.
- On existing model railroad car for dust collection, the upstream centrifugal fan creates a positive pressure in the dust collection chamber, which can cause dust to escape from the dust collection chamber.
- Existing model railroad car for dust collection requires a powered model railroad car such as a locomotive to be connected, because self-propelling is not possible. Therefore, in order to collect dust to the end of model railroad track, a turnaround may be necessary so that the model railroad car for dust collection first advances into the end.
- The present invention provides a model railroad car for dust collection having a structure which is harmonized with the other scale model, and wherein a centrifugal blower having a size equal to or larger than the existing model railroad car for dust collection can be installed.
- The present invention is characterized in including a dust collection nozzle which is open at the inferior of a vehicle body; a dust collection chamber which is positioned at the middle part of the vehicle body, is in communication with the dust collection nozzle, and is partitioned by a partition wall and a dust collection filter at the front and rear; a centrifugal blower installed horizontally in the front-rear direction of the vehicle body, with a dust collection fan which is a centrifugal fan oriented toward the dust collection filter; and an outlet at the periphery of the centrifugal fan; wherein one or more driving bogie(s) as a running gear can be installed.
- According to the present invention, the centrifugal blower can be housed in a vehicle body having a height of about the diameter of the centrifugal fan when installed horizontally, it can be mounted on a model of a work train such as a rail inspection car. In addition, restrictions on the length of the centrifugal blower in the rotational axis direction is also relaxed, therefore, there is an advantage of installing a larger centrifugal blower than in the existing model railroad car for dust collection even in a model of a small car of about 15 m in actual size.
- In the model railroad car for dust collection of the present invention, since the dust collection chamber is brought to negative pressure by the centrifugal fan installed downstream, there is less risk of dust leaking from the dust collection chamber. The dust collection filter is placed between the dust collection chamber and the centrifugal fan and is not exposed to the exterior of the vehicle, so it will not impair the exterior of the model.
- In the model railroad car for dust collection of the present invention, the centrifugal blower is installed horizontally, therefore, the outlet can be arbitrarily installed around the centrifugal fan, i.e., at any of four directions of both left and right sides, under the floor, and on the roof.
- The model railroad car for dust collection of the present invention is self-propelling by mounting a driving bogie as a running gear and can easily collect dust to the end of model railroad track.

FIG. 1 is an elevational view of an end of the model railroad car for dust collection; -
FIG. 2 is a cross-sectional view according to the section line A-A inFIG. 1 ; -
FIG. 3 is a cross-sectional view according to the section line B-B inFIG. 1 ; and -
FIG. 4 is a perspective view of thedust collection nozzle 14. - An example of the model railroad car for dust collection of the present invention will be described with reference to
FIGS. 1 to 4 . - Dust on
model railroad track 11 is drawn through adust collection nozzle 14 toward apath 8, and to adust collection chamber 6 in communication with thedust collection nozzle 14. Thedust collection chamber 6 is located at the middle part of the vehicle body partitioned bypartition wall 15 anddust collection filter 5 at the front and rear. The drawn dust is separated from the air by vacuum filtration through thedust collection filter 5 andcentrifugal fan 4. Theresidue 12 accumulated in thedust collection chamber 6 can be removed by opening a dustcollection chamber lid 7. In addition, a dust bag may be attached instead of thedust collection filter 5. - The air having passed through the
dust collection filter 5 is taken into thecentrifugal fan 4, and the air is discharged from anoutlet 3. Theoutlet 3 can be arbitrarily installed around thecentrifugal fan 4, i.e., at any of four directions of both left and right sides, under the floor, and on the roof. To the rotational axis of ablower motor 2 for driving thecentrifugal fan 4, it is desirable to install aflywheel 1 to be prepared for power outage. - The model railroad car for dust collection is equipped with a driving
bogie 16 which is equipped with adrive motor 9, and atrailing bogie 10 as running gears, so that it can be self-propelling to the end ofmodel railroad track 11. Incidentally, when connecting the model railroad car for dust collection as a trailer to a powered model railroad car such as a locomotive, the drivingbogie 16 is replaced with a trailing bogie, anddrive motor 9 is omitted. - The
dust collection nozzle 14 shown inFIG. 4 communicates to thedust collection chamber 6 from under the floor and has an opening with a width equal to or greater than the track gauge and equal to or less than the vehicle body width. -
