Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a filter mounting device, and particularly to a filter mounting device suitable for use in vehicles such as electric diesel locomotives.

Background of the invention A conventional mounting device of this type will be explained with reference to FIG.

That is, the filter 1 is attached to a window frame 2 of the vehicle body by a latch 3 and a spring 4, and the space between the window frame 2 of the vehicle body and the filter 1 is sealed by a packing 5.

To remove this filter 1, rotate the latch 3 while pulling it in the direction of arrow 8, remove it from the stopper 6, and remove the filter 1.

When installing, reverse the above steps. Such a filter mounting device has the inconvenience that the filter 1 cannot be mounted or removed with one touch.

In addition, since the latch 3 is easily damaged, sand, dirt, etc. can easily enter the latch 3, which increases the number of maintenance inspections.

Another disadvantage is that it requires a large number of parts such as latches and springs, making it expensive.

OBJECTS OF THE INVENTION The object of the present invention was to overcome the above-mentioned disadvantages and to provide a filter mounting device which is easy to install and remove, is robust and requires no maintenance.

Summary of the Invention The gist of the present invention is that a filter is installed in a window frame, and the upper part of the window frame is provided with a horizontal part and a hanging part.
A leaf spring is provided on the opposite side of the hanging part to press the upper side wall of the filter against a packing provided in the hanging part of the window frame when the filter is inserted, while the lower part of the window frame is opened upward. Formed into a U-shape with an opening,
This U-shaped opening rising piece on the leaf spring side is provided so as to be inclined outward, so that when the filter is inserted, the lower side wall of the filter can be pressed against the packing provided on the rising piece on the opposite side. be.

Examples of the invention An embodiment of the present invention will be described below with reference to FIG.

In FIG. 2, the upper part of the window frame 2 of the vehicle body into which the filter 1 is placed is a groove part 10 having a horizontal part 10a and a hanging part 10b, and the filter 1 is placed on the opposite side of the hanging part 10b.
A leaf spring 12 is provided that presses the upper side wall of the filter 1 against a packing 11 provided on the hanging portion 10b during insertion.

This plate 12 is fixed to a bracket 13 with screws.

On the other hand, the lower part of the window frame 2 is formed with a U-shaped groove 14 having an opening A that opens upward, and the inner rising piece 14a of this groove 14 is provided with an inclination inclined at an angle θ. When inserted, the lower side wall of the filter is pressed against the packing 11 provided on the rising piece 14b on the opposite side.

In this structure, when installing the filter 1, the filter 1 is inserted from above as shown by the two-dot chain line and then dropped into the groove 14 having an inclination θ.

In this state, the upper part of the filter 1 is pressed against the packing 11 by the leaf spring 12, and the lower part is pressed against the packing 11 by the wedge action caused by the contact between the corner of the filter 1 and the groove part 14 having an inclination θ, thereby maintaining airtightness. be done.

In addition, when removing the filter, lift the filter 1 upward and perform the operation opposite to the above-mentioned installation process.

As described above, according to one embodiment of the present invention, when attaching the filter to the window frame 2, the upper part of the filter 1 is attached to the leaf spring 12.
Since the lower part is pressed against and supported by the packing 11 by the groove portions 14 having an inclination θ, the pressing force of the plate spring 12 may be small, making installation and removal easy, and sufficiently preventing the intrusion of sand, dust, etc. I can do it.

Furthermore, since there are fewer damaged parts, maintenance and inspections are reduced, and the number of parts is reduced, resulting in extremely low cost.

Effects of the Invention According to the present invention, it is possible to obtain a filter mounting device that is extremely easy to attach and detach, is robust, and does not require maintenance.

Further, since the filter is pressed against the packing 11 at the upper and lower parts, airtightness can be sufficiently ensured.

Claims (1)

[Claims] 1 In the case where the filter is installed in a window frame, the upper part of the window frame is configured to be upside down with a horizontal part and a hanging part, and when the filter is inserted, the upper side wall of the filter is placed on the opposite side of the hanging part. A leaf spring is provided that presses against the packing provided on the hanging part, and the lower part of the window frame is formed into a U-shape with an opening that opens upward, and the opening rises on the side of the leaf of this U-shape. A filter mounting device characterized in that the pieces are provided so as to be inclined outward, so that when the filter is inserted, the lower side wall of the filter can be pressed against the packing provided on the rising piece on the opposite side.
