Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an air cleaner element mounting device used in small vehicles such as motorcycles or straddle-type four-wheeled vehicles.

[Prior art]

Generally, in small vehicles such as motorcycles or straddle-type four-wheeled vehicles, the air cleaner element can be attached or removed from the direction perpendicular to the direction of movement of the body frame in order to secure mounting space for auxiliary equipment attached to the body frame. There is something that was made to do so.

FIG. 4 is an exploded sectional view of an air cleaner 1 showing a conventional mounting device for the above-mentioned element, and in particular an air cleaner in which the element can be mounted and removed from above in the direction of movement (arrow A) of a vehicle body frame (not shown). This is what is shown.

In the box 2 of the air cleaner 1, an outlet 2b for the element 3 is formed at right angles above the axial direction of an outlet port 2a which discharges the sucked air (arrow B) to a carburetor (not shown). The element 3 is a so-called semi-wet type element, and is composed of a filter 4 made of urethane sponge and a frame 5 that extends the filter 4 over a cylindrical body with one end open. To install such an element 3 in the box 2, the open end 5a of the frame 5 is fitted into a rib 2c having a substantially triangular cross section formed in the outlet port 2a, and then the tip 2d of the rib 2c is inserted. and the closed end 5b of the frame 5 with the thumbscrew 6.
Further, the outlet 2b of the element 3 is covered with a lid 7, and this is fixed to the box 2 with screws 8 (FIG. 5).

By the way, according to the above-mentioned conventional mounting device, when attaching the element 3 using the thumbscrew 6, the female screw formed at the tip 2d of the rib 2c is inserted from the outlet 2b formed above the box 2. Since it is necessary to check the alignment (FIG. 4) between the part 2e and the hole 5c formed in the closed end 5b of the frame 5, it takes time to check and tighten the thumb screw. This was a factor that reduced the ease of assembly and maintenance and inspection of the air cleaner 1.

[Purpose of invention]

In view of the above-mentioned problems, this invention provides an air cleaner element mounting device that allows the element to be mounted in a short time by simple operation.

[Structure of the idea]

In order to achieve the above-mentioned object, this invention provides an air cleaner in which an outlet port and an element outlet are arranged in a cleaner box so that their respective axes are substantially orthogonal to each other. A lever is provided that swings toward the end of the element, contacts one end of the element to press the element into contact with the outlet port, and swings toward the other end to escape from the take-out area of the element, and the lever opens the take-out port. A protrusion is formed on the closing lid, which abuts the lever when covering the outlet and restricts the lever to swing in one direction.

〔Example〕

Hereinafter, one embodiment of the element mounting device according to the present invention will be described in detail.

FIG. 1 is an exploded sectional view of an air cleaner 10 to which the mounting device of the present invention is applied, and the same parts as in FIG. 4 are designated by the same reference numerals.

This air cleaner 10 is an air cleaner in which an element 3 can be attached and detached from above with respect to the traveling direction (arrow A) of a vehicle body frame (not shown), and the sucked air (arrow B) is placed in a cleaner box 11 (see arrow B). A take-out port 11b for the element 3 is formed perpendicularly above the axial direction of the outlet port 11a that discharges to the vaporizer. Further, a lever 13 is supported rotatably about a shaft 12 on the cleaner box 11 at a position facing the outlet port 11a. This lever 13 has its tip 13a connected to the frame closed end 5b of the element 3, and a convex portion 5d protruding from the center.
and press the element 3 between the peripheral edge 11c of the outlet port 11a and the tip 1 of the lever 13.
3a. Further, a stopper 11e is formed on the support portion 11d of the shaft 12 that supports the lever 13, and prevents the lever 13 from rotating beyond a predetermined rotation angle. omitted from
It rotates 90 degrees and stops at the position shown by the dashed line, that is, the position where element 3 is pressed. On the other hand, the lid 14 that closes the outlet 11b of the cleaner box 11 has a protrusion 14b formed on its back surface 14a. When covered, it comes into contact with the lever 13 and restricts its rotation. Note that FIG. 2 is a sectional view of FIG. 1 at CC, where reference numeral 11f represents an inlet port for sucking air (arrow B), and reference numeral 11g represents a baffle plate that forms a labyrinth inside the box 11.

Next, the operation of the above-described mounting device will be explained, and the structure will also be explained in more detail.

When installing the element 3, as shown in FIG.
Then, insert the element 3 and cover the outlet port 11a with this element 3. and,
When the lever 13 is rotated counterclockwise in the drawing,
The tip 13a of the lever 13 comes into pressure contact with the convex portion 5d of the element 3, and the element 3 is pressed between the outlet port 11a and the tip 13a of the lever 13. At this time, the rotation of the lever 13 is stopped by the stopper 11e. Thereafter, when the outlet 11b of the cleaner box 11 is covered with the lid 14, the tip 14c of the protrusion 14b formed on the lid 14 is exposed as shown in FIG. It comes into contact with the lever 13 and restricts the rotation of the lever 13. Therefore, attach the lid 14 to the cleaner box 11 with screws 16, etc.
When the lever 13 is tightened, the lever 13 is fixed and the element 3 is kept pressed and clamped within the cleaner box 11.

[Effect of idea]

In this invention, the element is installed in the cleaner box by a simple push-down operation using a lever, so that the installation work of the element does not take much time and the assembly and maintenance and inspection work are also easy.
