Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a sliding roof freight car. More specifically, the object of the present invention is to provide a roof moving device that can be easily moved from a closed state by human power when moving a plurality of roofs provided above a vehicle body above each other.

Conventionally, in the conventionally known sliding roof freight car described in Japanese Patent Publication No. 35-17959, both ends of the rail on which the roof car rides are sloped in the longitudinal direction, so that the roof in the closed state is It takes a lot of effort to lift the machine using the operating handle for the first time, and an improvement has been desired.

The present invention meets this need by making it possible to easily open and close the roof without being affected by the weight or weight of the roofing material.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an overall perspective view of a sliding roof freight car having left and right sliding roofs 3, 3' with the roof closed, in which 1 is the car body, 2 is a side sliding door, 3,
Reference numerals 3' denote left and right sliding roofs (hereinafter simply referred to as "roofs"), and 4 a rafter with a U-shaped cross section provided at the upper center of the car body, which connects the upper center of both side walls of the car body in an arch shape. Near the ends of the side plates of the left and right roofs 3 and 3', as shown in FIG. 10, a pair of roof wheels 11 are installed on the inner bearing 28 and the outer bearing 10, respectively, which are attached to the roof girder 9 on both sides of the vehicle center and vehicle end. (Fig. 5) and 29 (Fig. 8) are rotatably supported, and when the roof is closed, the roof wheel 11
As shown in FIGS. 4, 5, and 6, the vehicle has a ramp and a horizontal path that are pivoted via hinges 15 to the ends of outer rails 12 provided along the upper edge of the outer wall of the vehicle body. On the horizontal path of the rotating rail 14,
As shown in FIGS. 7 to 10, the roof wheel 29 is pivoted via a hinge 32 to the end of an inner rail 30, which is formed along the upper edge of the outer wall of the vehicle body and has an elongated upper section 21 shaped like a "F". It is located on a horizontal path of a supported rotary rail 31 similar to the above.

In this state, to explain the case where the worker on the left roof 3 opens the right roof 3', the handle 7 attached to the footboard 6 at the center of the roof 3' in the closed state of FIG. When the center is pulled up to the state shown in FIGS. 2 and 3 and then pulled parallel to the roof plate 5 in the direction of the arrow, the roof wheels 11 and 29 rotate as shown in FIGS. 6 and 9, respectively. The rails 14 and 31 move on the horizontal path toward the ramp as shown by the arrow, but first, each rotating rail 1
The bottom surface of the end of the horizontal path following the ramp bent diagonally upward at 4 and 31 is engaged with lower stoppers 20 and 39 protruding from the long outer wall of 21, so that the horizontal road surface of the rotating rail is held horizontally. Therefore, the roof 3' moves approximately horizontally. In this case, the outer rail 12 (sixth
The rotating rails 14 and 31, which are rotatably supported at the ends of the inner rail 30 (Fig. 7) and the inner rail 30 (Fig. A compressed coil spring 26 is installed between the spring seats 25, 36 attached to the rotary rails 14, 31 and the spring seats 24, 35 pivotally attached to the spring seats 22, 33 fixed to the lower surface of the ramp of each rotating rail 14, 31. , 37 causes a counterclockwise moment to be applied, causing the roof 3' to rotate upward.
The horizontal road bottom surface of the rotating rails 14, 31 is placed on the lower stopper 20, 39 which is located at the end of the horizontal road surface of the rotating rail in FIGS. kept in contact and closed.

Now, when the roof wheels 11, 29 move in the direction of the arrow and approach the ramp of the rotating rails 14, 31, the distance between the center of the hinges 15, 32 and the roof wheels 11, 29 becomes shorter, so the coil springs 26, 37 Rotating rails 14, 3 due to the counterclockwise moment caused by
1 rotates counterclockwise to push up the roof wheels 11 and 29, and an upper stopper 2 fixed to the vehicle body.
The rotating rails 14, 31 stop at the positions shown by the chain lines where the spring seats 22, 33 contact the spring seats 7, 38, and the ramps of the rotating rails 14, 31 become substantially horizontal and are connected in a straight line to the outer rail 12 and inner rail 30, respectively. Therefore, by simply applying a tensile force to horizontally move the roof through the handle 7, the roof wheels 11, 29 move from the position shown by the solid line in FIGS. 6 and 9 to above the outer rail 12 and the inner rail 30, as shown by the chain line. It rises like this and can run on this rail.

The outer rail 12 is provided with a notch approximately equal in length to the rotary rail 14, and near both ends of this notch are hinges 1, as seen in FIGS. 4 and 5.
Auxiliary rail 16 pivoted at both ends at 7 and 17'
compensates for this notch 13, and the outer bearing 10 of the right roof 3' can move horizontally within the gap 19 between the notch 13 and the auxiliary rail 16. When the rotating rail of the right roof 3' rotates upward and pushes up the roof wheel 11 to the position shown by the chain line, the auxiliary rail 16 is pushed up by the outer bearing 10 and reaches the position shown by the chain line.
The roof wheel 11 that has risen can move from the rotating rail 14 to the outer rail 12. When the right roof 3' is closed, use the auxiliary rail 1 as shown.
Reference numeral 6 denotes an outer rail 12 that fills the notch of the outer rail 12 and through which the roof wheel on the left roof 3 on the side of the center of the vehicle body passes.
constitutes part of.

On the other hand, the roof wheel 29 is provided with an inner rail 3 provided on the upper edge of the long 21 as shown in FIGS. 7 to 10.
Can move above 0.

The above has described the operation for opening a roof that is in a closed state, but once a roof has been opened, closing it can be easily accomplished by performing the opposite operation.

In this embodiment, a case has been described in which the shapes and sizes of the rotating rails 14 and 31 are set to be approximately the same, but when closing an open roof by appropriately selecting the length of the horizontal path of each rotating rail, After one roof truck ascends the inclined surface (horizontal path) of the rotating rail, the rotating rail rotates clockwise due to the load of the roof applied to the roof truck, and as the roof truck begins to descend, the other roof truck rises. The effort required during operation can be reduced by starting to ascend the horizontal path during the slope of the rotating rail.

In addition, although we have explained the case where the rotating rail is given a tendency to rotate counterclockwise by the elastic force of the spring,
Other actuators may also be used.

According to the present invention configured as described above, when opening and closing the roof, it is possible to extremely smoothly transfer the roof wheel from the rotating rail onto the inner rail and the outer rail, respectively, and from the inner rail and the outer rail to the rotating rail. Moreover, it is lighter and easier to operate than the conventional method in which the roof is raised by manual lever operation and a fixed ramp.
