Description

The present invention relates to a push-in cap and a method for assembling a push-in cap.

Conventionally, a cover described in Patent Document 1 is known as a member for blocking the air intake of a moving body. This cover is attached to the air intake of the engine when the engine of the moving body is stopped, blocking the air intake. This prevents foreign objects from entering through the air intake when the engine is stopped. This prevents damage to the engine.

Embodiments of the present invention are listed below.

A push-in cap that is fitted into an intake or exhaust port of a moving body, the push-in cap having a cap body that closes the intake or exhaust port when fitted into the intake or exhaust port and has a cap outer surface that faces the inner wall of the intake or exhaust port, and a non-slip portion that is arranged on at least a part of the cap outer surface of the cap body, the non-slip portion being formed of a material with a higher friction coefficient than the cap outer surface and abutting against the inner wall of the intake or exhaust port. The non-slip portion abuts against the inner wall of the intake or exhaust port, thereby holding the push-in cap in a state where it cannot be removed from the intake or exhaust port. This makes it possible to prevent the push-in cap from falling off the intake or exhaust port.

When the cap body is fitted inside the intake port or exhaust port, the anti-slip portion is located in a portion of the cap body near the front end in the direction in which the intake port or exhaust port opens, and the rear side of the cap body in the direction in which the intake port or exhaust port opens faces the intake port or exhaust port with the outer surface of the cap facing the intake port or exhaust port. This allows the anti-slip portion to come into contact with the inner wall of the intake port or exhaust port in the final stage of fitting, improving the workability when fitting the push-in cap inside the intake port or exhaust port.

The anti-slip portions are arranged at intervals in the circumferential direction of the cap body. This reduces the insertion force required to insert the push-in cap into the intake or exhaust port, improving the ease of inserting the push-in cap into the intake or exhaust port.

The cap body comprises an elastic material that can be elastically deformed, and a skin material that covers the elastic material, and the skin material forms the outer surface of the cap. The elastic material is elastically deformed, so that the outer shape of the push-in cap can be deformed to correspond to the shape of the inner wall of the intake or exhaust port. This makes it easier to insert the push-in cap into the intake or exhaust port, and also prevents the push-in cap from falling off the intake or exhaust port.

The elastic material includes a soft elastic material located on the inner wall side of the intake port or the exhaust port when the cap body is fitted inside the intake port or the exhaust port, and a hard elastic material located on the opposite side of the inner wall of the intake port or the exhaust port and having a higher elastic modulus than the soft elastic material. The soft elastic material is easily deformed, so that the outer shape of the push-in cap can be changed in accordance with the inner shape of the intake port or the exhaust port. As a result, the insertion force required to insert the push-in cap into the intake port or the exhaust port can be reduced. In addition, it is possible to accommodate variations in the manufacturing dimensions of the intake port or the exhaust port. Furthermore, since the outer shape of the push-in cap is maintained by the hard elastic material, the friction force between the anti-slip portion and the inner wall of the intake port or the exhaust port can be maintained. This makes it possible to prevent the push-in cap from falling off the intake port or the exhaust port.

The cap body comprises a plurality of divided bodies, each of which comprises an inner surface where the divided bodies face each other, and an outer surface where the divided bodies face the inner wall of the intake port or the exhaust port, and the anti-slip portion is disposed on the outer surface of the divided body. This improves workability compared to when one large push-in cap is fitted inside the intake port or the exhaust port. Furthermore, by providing each of the divided bodies with an anti-slip portion, it is possible to prevent each divided body from falling off the intake port or the exhaust port.

Furthermore, a pressing device is provided that presses the multiple divided bodies in different directions to press the multiple divided bodies against the inner wall of the intake port or exhaust port. This allows the multiple divided bodies to be firmly pressed against the inner wall of the intake port or exhaust port, further preventing the push-in cap from falling off the intake port or exhaust port.

The pressing device is disposed on one of the plurality of divided bodies, and a pressing force receiving portion that receives a pressing force from the pressing device is disposed on the other divided body, and the pressing device is formed long in a pressing direction in which the divided body is pressed against the inner wall of the intake port or the exhaust port, and is provided with a shaft that is movable in the pressing direction, and the pressing force receiving portion includes a locking portion with which the end of the shaft abuts in the pressing direction, and a hooking portion with which the side of the shaft is hooked from the rear in the opening direction of the intake port or the exhaust port. The pressing force of the pressing device is received by the pressing force receiving portion, so that the plurality of divided bodies are pressed against the inner wall of the intake port or the exhaust port. This can further prevent the push-in cap from falling off the intake port or the exhaust port. In addition, the end of the shaft abuts against the locking portion, so that the plurality of divided bodies are pressed against the inner wall of the intake port or the exhaust port. This further prevents the push-in cap from falling off the intake port or the exhaust port. In addition, the side of the shaft hooks onto the hook portion, preventing the multiple segments from moving forward in the opening direction. This further prevents the push-in cap from falling off the intake or exhaust port.

The pressure receiving portion has a locking hole, which is a bottomed hole drilled in the pressing direction, the bottom of the locking hole is the locking portion, and the inner surface of the locking hole is the hook portion. The locking portion and the hook portion can be formed by the simple method of forming a locking hole in the pressure receiving portion.

When each of the multiple segments is pressed by the pressing device, the anti-slip portion is disposed on at least the surface of the outer surface of the segment that is pressed against the inner wall of the intake port or the exhaust port by the pressing device. This further prevents the push-in cap from falling off the intake port or the exhaust port.

Furthermore, the cap is provided with a flexible hinge that connects adjacent segments of the plurality of segments, and the hinge is disposed on the rear surface of the cap outer surface in the opening direction of the intake or exhaust port, in a manner that straddles adjacent edges of the adjacent segments. As a result, when inserting the push-in cap into the intake or exhaust port, the arrangement of the plurality of segments can be easily adjusted, thereby improving the efficiency of the assembly work of the push-in cap.

Furthermore, at least one of the divided bodies has a first hook portion, and at least one of the divided bodies different from the divided body having the first hook portion has the first hook portion and a second hook portion that hooks from the front in the opening direction of the intake port or the exhaust port, and the first hook portion and the second hook portion hook together to prevent at least the divided body having the first hook portion and the divided body having the second hook portion from moving in a direction that causes them to fall off the intake port or the exhaust port. The simple method of hooking the first hook portion and the second hook portion can further prevent the push-in cap from falling off the intake port or the exhaust port.

The inner wall of the intake or exhaust port is tapered to become narrower as it approaches the back of the intake or exhaust port. When a push-in cap is fitted into an intake or exhaust port of this shape, the push-in cap is relatively easy to remove. In such cases, the push-in cap of the present invention is effective.

A push-in cap that is fitted into an intake or exhaust port of a moving body, the push-in cap includes a cap body that closes the intake or exhaust port when fitted into the intake or exhaust port and has multiple divided bodies, and a pressing device that presses the multiple divided bodies in different directions to press the multiple divided bodies against the inner wall of the intake or exhaust port. The pressing device presses the multiple divided bodies against the inner wall of the intake or exhaust port, thereby preventing the push-in cap from falling off the intake or exhaust port.

A push-in type cap that is fitted into an intake or exhaust port of a moving body, the push-in cap having a cap outer surface that blocks the intake or exhaust port when fitted into the intake or exhaust port and that faces the inner wall of the intake or exhaust port, and a non-slip portion that is arranged on at least a part of the cap outer surface of the cap body, the non-slip portion being formed of a material with a friction coefficient greater than that of the cap outer surface and abutting against the inner wall of the intake or exhaust port, the cap body having a plurality of divided bodies, each of the plurality of divided bodies having a divided body inner surface where the plurality of divided bodies face each other, and a divided body outer surface where the plurality of divided bodies face the inner wall of the intake or exhaust port, A method for assembling a push-in cap, in which the anti-slip portion is disposed on the outer surface of the divided body, is fitted into the intake port or the exhaust port, and includes the steps of: inserting the divided bodies into the intake port or the exhaust port with the divided body outer surface of the divided body disposed on the rear side in the opening direction of the intake port or the exhaust port and the divided body inner surface disposed on the front side in the opening direction; and pushing the end portion of the divided bodies of the push-in cap inserted into the intake port or the exhaust port that is located on the front side in the opening direction backward in the opening direction, so that the anti-slip portion abuts against the inner wall of the intake port or the exhaust port, and attaching the push-in cap to the intake port or the exhaust port in a non-removable state.

The above-mentioned method of assembling the push-in cap can prevent the push-in cap from falling off the intake or exhaust port.

The plurality of segments are provided with a guide slope on the outer surface of the segment at a rear position in the opening direction, the width of which narrows toward the rear in the opening direction, and the process of inserting the plurality of segments into the intake port or the exhaust port includes a process of inserting the push-in cap into the intake port or the exhaust port while bringing the guide slope into contact with the opening edge of the intake port or the exhaust port.

When attempting to insert multiple segments into an intake or exhaust port from the front in the opening direction, the segments make it difficult to see the intake or exhaust port. For this reason, by bringing the guide slopes formed on the segments into contact with the opening edge of the intake or exhaust port, the multiple segments can be easily inserted into the intake or exhaust port.

After the step of pushing the ends of the multiple segments located on the front side in the opening direction rearward in the opening direction, the multiple segments are prevented from moving in a direction that would cause them to fall out of the intake or exhaust port by abutting the inner faces of the multiple segments. By using the simple method of abutting the ends of the multiple segments on the opposite side to the inner wall of the intake or exhaust port against each other, the push-in cap can be further prevented from falling out of the intake or exhaust port.

After pushing the divided bodies backward in the opening direction, the process includes pressing the divided bodies against the inner wall of the intake port or the exhaust port. This further prevents the push-in cap from falling off the intake port or the exhaust port.

A method for assembling a press-in type cap, which is fitted into an intake port or exhaust port of a moving body, and which closes the intake port or exhaust port when fitted into the intake port or exhaust port, and which includes a cap body having a plurality of divided bodies and a pressing device that presses the plurality of divided bodies against the inner wall of the intake port or exhaust port by pressing the plurality of divided bodies in different directions, is performed by fitting the press-in type cap into the intake port or exhaust port, and the outer surface of one of the plurality of divided bodies that faces the inner wall of the intake port or exhaust port is pressed against the intake port or exhaust port. The method includes the steps of inserting the multiple segments into the intake or exhaust port with the opposing inner faces of the segments positioned at the front in the opening direction, pushing the ends of the multiple segments of the push-in cap inserted into the intake or exhaust port that are positioned at the front in the opening direction toward the rear in the opening direction, and pressing the outer faces of the multiple segments against the inner wall of the intake or exhaust port using the pressing device to attach the push-in cap to the intake or exhaust port in a non-removable state.

The above-mentioned method of assembling the push-in cap can prevent the push-in cap from falling off the intake or exhaust port.

(Embodiment 1)
A first embodiment will be described with reference to FIG. 1. A push-in cap 10a according to this embodiment is fitted into an intake port 2 formed in a moving body 1. In the following description, the front of the moving body 1 in the direction of travel is the front, and the rear is the rear. The up-down direction is the direction of gravity. The left-right direction is the direction perpendicular to both the front-rear direction and the up-down direction. However, the above directions are for convenience of description and do not limit the invention. In addition, for multiple identical components, only some of the components may be labeled with a reference symbol, and the reference symbols may be omitted for the other components.

1, an inlet 3 that opens downward is formed on the bottom surface of the moving body 1. The moving body 1 can be any moving body 1, such as a vehicle such as an automobile or motorcycle, or a ship. The inlet 3 is not limited to being formed on the bottom surface of the moving body 1, and may be formed in any position, such as the top surface, right side surface, left side surface, front surface, or rear surface.

The inlet 3 in this embodiment is formed so that the upward recess dimension increases toward the rear. An air intake 2 is formed at the rear end of the inlet 3. The air intake 2 opens forward inside the inlet 3. The air intake 2 is connected to an engine (not shown) and supplies air to the engine. The air intake 2 is formed as a hollow cylinder that extends in the front-to-rear direction (one example of the opening direction) as a whole. In this embodiment, the inner wall of the air intake 2 is mirror-finished. Although not shown in detail, the inner wall of the air intake 2 is formed in a tapered shape that narrows toward the rear.

However, the inner wall of the intake port 2 does not have to be mirror-finished. Also, the inner wall of the intake port 2 may be formed to have the same inner diameter dimension in the front-to-rear direction, or may be formed in a tapered shape that becomes wider toward the rear.

The intake port 2 in this embodiment is formed in the shape of a long hole that is long in the left-right direction. The intake port 2 is formed asymmetrically. Furthermore, the intake port 2 is formed asymmetrically up-down. However, the shape of the intake port 2 is not limited to the above, and can be any shape, such as a circle, an ellipse, a track, or a polygonal shape such as a triangle or a square. Furthermore, the intake port 2 may be formed symmetrically up-down or left-right.

2, the push-in cap 10a is fitted into the air intake 2 of the moving body 1 when the engine is stopped. This makes it possible to prevent wind, rain, sand, insects, small animals, and other foreign objects from entering through the air intake 2. As a result, it is possible to prevent malfunctions in the engine.

As shown in Figures 2 and 3, the push-in cap 10a is generally formed in a shape that follows the internal shape of the intake port 2. As described above, the intake port 2 is asymmetrical in shape, and the push-in cap 10a is also asymmetrical in shape. In addition, the intake port 2 is asymmetrical in shape from top to bottom, and the push-in cap 10a is also asymmetrical in shape from top to bottom. However, the push-in cap 10a may be formed symmetrically or symmetrically.

The push-in cap 10a includes a cap body 11 and an anti-slip portion 12. However, the anti-slip portion 12 may be omitted. The cap body 11 is divided into two in the left-right direction. The cap body 11 includes a first divided body 11a arranged on the right side and a second divided body 11b arranged on the left side. The left-right length dimension of the first divided body 11a and the left-right length dimension of the second divided body 11b are set to be approximately the same. The cap body 11 includes a cap outer surface 11c that faces the inner wall of the intake port 2. In addition, the first divided body 11a and the second divided body 11b include a divided body outer surface 11d that faces the inner wall of the intake port 2. In addition, the first divided body 11a and the second divided body 11b include divided body inner surfaces 11e that face each other (see FIG. 9). In this embodiment, the first divided body 11a and the second divided body 11b have different shapes.

However, the cap body 11 may be configured to have three or more divided bodies. Furthermore, the shapes of the divided bodies may be the same or different.

(1) First divided body 11a
As shown in Fig. 2, the first divided body 11a is formed in a generally rectangular shape that is elongated in the left-right direction when viewed from the front. When the cap 10a is fitted into the intake port 2, the cap 10a is provided with a front wall 13 located at the front side, an upper wall 14 extending rearward from the upper end of the front wall 13, and a lower wall 14 extending rearward from the lower end of the front wall 13. The length dimension of the upper wall 14 in the front-rear direction is greater than the length dimension of the lower wall 15 in the front-rear direction.

As shown in FIG. 4, the first division 11a comprises a core material 21, a hard elastic material 22, a soft elastic material 23, and a skin material 24.

The core material 21 is formed in a flat plate shape in the front-rear direction. There are no particular limitations on the material that constitutes the core material 21, and any material, such as resin, metal, rubber, etc., can be selected as appropriate. As for the resin, any resin, such as polyamide, polyester, polyolefin, etc., can be selected. As for the metal, any metal, such as SUS, aluminum, etc., can be selected. As for the rubber, any rubber, such as natural rubber, synthetic rubber, etc., can be selected.

The core material 21 constitutes the front wall 13. A hard elastic material 22 is disposed on the upper edge of the core material 21, extending rearward. The upper edge of the core material 21 and the hard elastic material 22 may be bonded together. A hard elastic material 22 is also disposed on the lower edge of the core material 21, extending rearward. The lower edge of the core material 21 and the hard elastic material 22 may be bonded together.

The hard elastic material 22 is made of a foamed resin that can be elastically deformed. Any foamed resin can be selected as the foamed resin that constitutes the hard elastic material 22, such as foamed polyethylene, foamed polypropylene, or hard foamed polyurethane.

The hard elastic material 22 is laminated with a soft elastic material 23 having a smaller elastic modulus than the hard elastic material 22. In other words, the elastic modulus of the hard elastic material 22 is larger than that of the soft elastic material 23. The soft elastic material 23 is disposed outside the hard elastic material 22 in the vertical direction. The vertical thickness of the hard elastic material 22 is set smaller than the vertical thickness of the soft resin. However, the vertical thickness of the hard elastic material 22 may be the same as the vertical thickness of the soft resin, or may be set smaller.

The soft elastic material 23 is made of a foamed resin that can be elastically deformed. As the foamed resin that constitutes the soft elastic material 23, foamed rubber such as natural rubber foam or synthetic rubber foam, soft polyurethane, etc. can be suitably used.

When the cap body 11 is fitted inside the intake port 2, the soft elastic material 23 is located on the inner wall side of the intake port 2. The soft elastic material 23 easily elastically deforms, so that the cap body 11 can be easily fitted inside the intake port 2. In addition, the hard elastic material 22 allows the shape of the cap body 11 to be maintained.

The skin material 24 covers the core material 21, the hard elastic material 22, and the soft elastic material 23. The outer surface of the skin material 24 forms the cap outer surface 11c. The material that forms the skin material 24 can be, for example, canvas made of woven fabric coated with a synthetic resin material such as polyvinyl chloride. The woven fabric is flexible.

As shown in FIG. 4, a front plate 31 is disposed on the front surface of the front wall 13 of the first divided body 11a. The front plate 31 in this embodiment is made of metal, and is formed slightly larger above, to the right, and below than the core material 21 when viewed from the front. Any metal can be selected as the metal constituting the front plate 31, such as SUS or aluminum. However, the front plate 31 may also be made of a resin such as polyolefin, polyamide, or polyester. The front plate 31 may also be omitted.

As shown in FIG. 4, a rear plate 32 is disposed on the rear surface of the front wall 13 of the first divided body 11a. The rear plate 32 is made of metal. The vertical length dimension of the rear plate 32 is set to be approximately the same as that of the core material 21. The upper and lower ends of the rear plate 32 are bent rearward. This connects the front wall 13 to the upper wall 14 and the lower wall 15 by the rear plate 32. Any metal can be selected as the metal constituting the rear plate 32, such as SUS or aluminum. However, the rear plate 32 may be made of a resin such as polyolefin, polyamide, or polyester. The rear plate 32 may also be omitted.

As shown in FIG. 4, the front plate 31, the skin material 24, the core material 21, and the rear plate 32 are fixed by bolts 33 and nuts 34. However, the bolts 33 and nuts 34 may be sealed by a sealing member (not shown). The same applies to the following description.

As shown in Figures 2 and 3, a handle 35 is fixed to the front surface of the first divided body 11a. As shown in Figure 3, the handle 35 is made of metal and is formed in a roughly U-shape when viewed from above. As shown in Figures 5 and 6, the handle 35 is fixed to the front plate 31, the skin material 24, the core material 21, and the rear plate 32 by a bolt 33 that passes through the front plate 31, the skin material 24, the core material 21, and the rear plate 32. However, the material constituting the handle 35 is not particularly limited, and any material such as resin, leather, or cloth can be appropriately selected. Furthermore, the means for fixing the handle 35 to the first divided body 11a is not limited to bolt fastening, and any fixing means such as sewing or adhesive can be selected.

As shown in Figs. 2 and 3, a toggle clamp 36 (an example of a pressing device) is fixed by a bolt 33 to a position on the front surface of the first divided body 11a near the left end. The toggle clamp 36 includes a base 36a, an axis 36b, a lever 36c, and a stroke shaft 36d (an example of a shaft). The lever 36c is formed to be rotatable around the axis 36b arranged on the base 36a. By rotating the lever 36c, the stroke shaft 36d moves left and right (an example of a pressing direction). In this embodiment, when the tip of the lever 36c is rotated in a direction approaching the front plate 31, the stroke shaft 36d moves leftward. However, when the tip of the lever 36c is rotated in a direction approaching the front plate 31, the stroke shaft 36d may also move rightward.

However, the pressing device is not limited to the toggle clamp 36, but may be, for example, a long shaft in the left-right direction with a screw thread formed on its outer periphery, and any configuration may be selected as appropriate.

As shown in FIG. 3, a chamfered guide slope 25 is formed on the right rear end of the upper wall 14 of the first divided body 11a. The guide slope 25 is narrower toward the rear in the opening direction of the intake port 2.

As shown in FIG. 5, a first anti-slip portion 12a is disposed on the right edge of the first divided body 11a (the right side surface of the upper wall 14, the right side surface of the front wall 13, and the right side surface of the lower wall 15). The first anti-slip portion 12a is formed of a material with a higher friction coefficient than the skin material 24. The material constituting the first anti-slip portion 12a is not particularly limited, and any material can be appropriately selected, such as rubber such as natural rubber, synthetic rubber, and silicone rubber, or elastomers such as styrene-based thermoplastic elastomers, olefin-based thermoplastic elastomers, and dynamically crosslinked thermoplastic elastomers. The material constituting the first anti-slip portion 12a may also be, for example, a material in which a woven fabric is impregnated with rubber such as natural rubber, synthetic rubber, and silicone rubber, or an elastomer.

Although not shown in detail, a soft elastic material is disposed inside the first anti-slip portion 12a. As a result, when the first anti-slip portion 12a is pressed against the inner wall of the intake port 2, the soft elastic material is elastically deformed, generating a resilient force that urges the first anti-slip portion 12a against the inner wall of the intake port 2. As a result, the first anti-slip portion 12a is strongly pressed against the inner wall of the intake port 2. As a result, the frictional force between the first anti-slip portion 12a and the inner wall of the intake port 2 increases, so that the push-in cap 10a is prevented from falling off the intake port 2. However, a hard elastic material may be disposed inside the first anti-slip portion 12a. The soft elastic material may also be omitted.

(2) Second divided body 11b
As shown in Fig. 2, the second divided body 11b is formed in a generally rectangular shape that is elongated in the left-right direction when viewed from the front. The first divided body 11a and the second divided body 11b are As a result, when the first divided body 11a and the second divided body 11b are fitted into the intake port 2, the second divided body 11b is fitted on the right side and the first divided body 11b is fitted on the left side. This can prevent the body 11a from being embedded.

As shown in FIG. 6, when the push-in cap 10a is inserted into the intake port 2, the second divided body 11b has a front wall 13 located at the front side, an upper wall 14 extending rearward from the upper end of the front wall 13, and a lower wall 15 extending rearward from the lower end of the front wall 13. The length of the upper wall 14 in the front-to-rear direction is greater than the length of the lower wall 15 in the front-to-rear direction.

Although not shown in detail, the second divided body 11b, like the first divided body 11a, comprises a core material 21, a hard elastic material 22, a soft elastic material 23, and a skin material 24. The core material 21, hard elastic material 22, soft elastic material 23, and skin material 24 that constitute the second divided body 11b are the same as those of the first divided body 11a, so a duplicated description will be omitted.

As shown in FIG. 6, a front plate 31 is disposed on the front surface of the front wall 13 of the second divided body 11b. The front plate 31 is made of metal and is formed slightly larger above, to the right, and below than the core material 21 when viewed from the front. The metal constituting the front plate 31 can be any metal, such as SUS or aluminum.

As shown in FIG. 6, a rear plate 32 is disposed on the rear surface of the front wall 13 of the second divided body 11b. The rear plate 32 is made of metal. The vertical length of the rear plate 32 is set to be approximately the same as that of the core material 21. The upper and lower ends of the rear plate 32 are bent rearward. This connects the front wall 13 to the upper wall 14 and the lower wall 15 via the rear plate 32. Any metal can be selected as the metal constituting the rear plate 32, such as SUS or aluminum. However, the front plate 31 may be made of a resin such as polyolefin, polyamide, or polyester. The front plate 31 may also be omitted.

As shown in FIG. 6, the front plate 31, the skin material 24, the core material 21, and the rear plate 32 are fixed by bolts 33 and nuts 34.

As shown in Figures 2 and 3, a handle 35 is fixed to the front surface of the second divided body 11b. As shown in Figure 3, the handle 35 is formed in a substantially U-shape when viewed from above. The handle 35 is fixed to the front plate 31, the skin material 24, the core material 21, and the rear plate 32 by bolts 33 that pass through the front plate 31, the skin material 24, the core material 21, and the rear plate 32.

As shown in Figures 2 and 3, a locking block 37 (an example of a pressure-receiving portion) is fixed to the front surface of the second section 11b at a position toward the right end. The locking block 37 is fixed to the front plate 31 by a bolt 33.

The material constituting the locking block 37 is not particularly limited, and any material can be selected, such as metals such as SUS and aluminum, and resins such as polyamide, polyester, and polyolefin. The locking block 37 is formed in a roughly rectangular parallelepiped shape.

As shown in Figures 2 and 3, with the first and second divisions 11a and 11b inserted into the intake port 2, the lever 36c of the toggle clamp 36 is rotated and the tip of the stroke shaft 36d abuts against the right side of the locking block 37 from the right, pressing the first division 11a to the right and the second division 11b to the left. This presses the right side wall of the first division 11a against the inner wall of the intake port 2 and presses the left side wall of the second division 11b against the inner wall of the intake port 2. As a result, the first division 11a and the second division 11b are prevented from slipping out of the intake port 2.

As shown in FIG. 3, a chamfered guide slope 25 is formed on the left rear end of the upper wall 14 of the second divided body 11b. The guide slope 25 is narrower toward the rear in the opening direction of the intake port 2.

As shown in FIG. 6, the second anti-slip portion 12b is disposed on the left edge of the second divided body 11b (the left side surface of the upper wall 14, the left side surface of the front wall 13, and the left side surface of the lower wall 15). The second anti-slip portion 12b is formed of a material having a larger friction coefficient than the skin material 24. The material constituting the second anti-slip portion 12b is not particularly limited, and any material can be appropriately selected, such as rubber such as natural rubber, synthetic rubber, and silicone rubber, or elastomers such as styrene-based thermoplastic elastomers, olefin-based thermoplastic elastomers, and dynamically crosslinked thermoplastic elastomers. The material constituting the second anti-slip portion 12b may be, for example, a material in which a woven fabric is impregnated with rubber such as natural rubber, synthetic rubber, and silicone rubber, or an elastomer. The material constituting the second anti-slip portion 12b may be the same material as the first anti-slip portion 12a, or a different material.

Although not shown in detail, a soft elastic material is disposed inside the second anti-slip portion 12b. As a result, when the second anti-slip portion 12b is pressed against the inner wall of the intake port 2, the soft elastic material is elastically deformed, generating a resilient force that urges the second anti-slip portion 12b against the inner wall of the intake port 2. As a result, the second anti-slip portion 12b is strongly pressed against the inner wall of the intake port 2. As a result, the frictional force between the second anti-slip portion 12b and the inner wall of the intake port 2 increases, so that the push-in cap 10a is prevented from falling off the intake port 2. However, a hard elastic material may be disposed inside the second anti-slip portion 12b. The soft elastic material may also be omitted.

As shown in FIG. 3, the left end of the upper wall 14 of the first division 11a and the right end of the upper wall 14 of the second division 11b are connected by a hinge 26. The hinge 26 is flexible and formed in a long rectangular shape. The hinge 26 may be glued or sewn to the first division 11a and the second division 11b. The length of the hinge 26 allows the first division 11a and the second division 11b to be separated by a predetermined distance, while preventing the first division 11a and the second division 11b from being separated by more than the length of the hinge 26.

The material constituting the hinge 26 is not particularly limited, and any material can be selected, such as cloth, leather, plastic, etc. The hinge 26 may be formed, for example, from canvas, which is a woven fabric coated with resin. The material constituting the hinge 26 and the material constituting the skin material 24 may be the same or different. However, the hinge 26 may be omitted.

3. End Treatment of Anti-Slip Part 12 The fixing structure of the second anti-slip part 12b and the covering material 24 will be described with reference to Fig. 7 and Fig. 8. However, for the sake of convenience, the hard elastic material 22 and the soft elastic material 23 are omitted in Fig. 7 and Fig. 8.

Figure 7 shows the fixing structure of the left end of the second anti-slip portion 12b with the covering material 24. As shown in Figure 7, the front edge of the second anti-slip portion 12b is folded inward and sewn with sewing thread 27 together with the left edge of the covering material 24 covering the front surface of the second divided body 11b and the front edge of the covering material 24 covering the left side surface of the second divided body 11b. This prevents a step from being formed with the front edge of the second anti-slip portion 12b exposed, and prevents the thread from fraying from the front edge of the second anti-slip portion 12b.

Similarly, the rear edge of the second anti-slip portion 12b is folded inward and sewn with sewing thread 27 together with the left edge of the skin material 24 covering the rear surface of the second divided body 11b and the rear edge of the skin material 24 covering the left side surface of the second divided body 11b. This prevents a step from being formed with the rear edge of the second anti-slip portion 12b exposed, and prevents the thread from fraying from the rear edge of the second anti-slip portion 12b.

As shown in Figure 8, the upper edge of the second anti-slip portion 12b attached to the left edge of the top wall 14 of the second divided body 11b is folded back downward and sewn with thread 27 to the skin 24 covering the left side of the top wall 14 of the second divided body 11b. The lower edge of the second anti-slip portion 12b attached to the left edge of the top wall 14 of the second divided body 11b is folded back inward and sewn with thread 27 together with the lower edge of the skin 24 covering the left side of the top wall 14 of the second divided body 11b and the left edge of the skin 24 covering the lower side of the top wall 14 of the second divided body 11b. This prevents the formation of a step when the upper and lower edges of the second anti-slip portion 12b attached to the left edge of the upper wall 14 of the second divided body 11b are exposed, and prevents the thread from fraying from the upper and lower edges of the second anti-slip portion 12b attached to the left edge of the upper wall 14 of the second divided body 11b.

As shown in Figure 8, the lower edge of the second anti-slip portion 12b attached to the left edge of the bottom wall 15 of the second partition 11b is folded back upward and sewn with thread 27 to the skin 24 covering the left side of the bottom wall 15 of the second partition 11b. The upper edge of the second anti-slip portion 12b attached to the left edge of the bottom wall 15 of the second partition 11b is folded back inward and sewn with thread 27 together with the upper edge of the skin 24 covering the left side of the bottom wall 15 of the second partition 11b and the left edge of the skin 24 covering the upper surface of the bottom wall 15 of the second partition 11b. This prevents the formation of a step when the upper and lower edges of the second anti-slip portion 12b attached to the left edge of the bottom wall 15 of the second divided body 11b are exposed, and prevents the thread from fraying from the upper and lower edges of the second anti-slip portion 12b attached to the left edge of the bottom wall 15 of the second divided body 11b.

The fixing structure between the first anti-slip portion 12a and the skin material 24 is the same as the fixing structure between the second anti-slip portion 12b and the skin material 24, so a duplicated explanation will be omitted.

3 and 9 to 10, a process of assembling the push-in cap 10a to the intake port 2 and a process of removing the push-in cap 10a from the intake port 2 will be described. However, the process of assembling the push-in cap 10a to the intake port 2 and the process of removing the push-in cap 10a from the intake port 2 are not limited to the following description.

As shown in FIG. 9, the lever 36c of the toggle clamp 36 is rotated to move the stroke shaft 36d of the toggle clamp 36 to the right. The first divided body 11a and the second divided body 11b are arranged so as to be bent around the hinge 26 as an axis.

In other words, with the first division 11a and the second division 11b arranged side by side in the longitudinal direction of the intake port 2, the ends of the first division 11a and the second division 11b near the longitudinal center position are arranged to protrude forward in the opening direction of the intake port 2. In other words, with the division inner surfaces 11e of the first division 11a and the second division 11b facing each other, the ends of the division inner surface 11e side are arranged to protrude forward in the opening direction of the intake port 2.

In the above state, the operator can easily perform the work by grasping the handle 35.

The operator, while holding the handle 35, brings the first division 11a and the second division 11b close to the intake port 2 from the front. Then, the guide slope 25 of the first division 11a and the guide slope 25 of the second division 11b come into contact with the opening edge of the intake port 2. As a result, the guide slope 25 of the first division 11a and the guide slope 25 of the second division 11b act as guides to insert the first division 11a and the second division 11b into the intake port 2. When attempting to insert the first division 11a and the second division 11b into the intake port 2 from the front, the first division 11a and the second division 11b make it difficult to see the intake port 2. For this reason, a configuration in which the guide slope 25 of the first division 11a and the guide slope 25 of the second division 11b act as guides is effective.

The first and second divisions 11a and 11b are then pressed forward to insert the first and second divisions 11a and 11b into the intake port 2 as shown in FIG. 10. In this state, the first anti-slip portion 12a of the first division 11a may abut against the inner wall of the intake port 2, and the second anti-slip portion 12b of the second division 11b may abut against the inner wall of the intake port 2. In this case, the first and second divisions 11a and 11b can be positioned within the intake port 2. However, in the state shown in FIG. 10, the first and second anti-slip portions 12a and 12b may be separated from the inner wall of the intake port 2.

As shown in FIG. 3, the lever 36c of the toggle clamp 36 is rotated to move the stroke shaft 36d to the left. This causes the left end of the stroke shaft 36d to abut against the right side of the locking block 37 from the right. As a result, the outer surfaces 11d of the first and second divisions 11a and 11b are pressed against the inner wall of the intake port 2.

Then, the first anti-slip portion 12a on the right side wall of the first divided body 11a is pressed from the left against the inner wall of the intake port 2. Also, the second anti-slip portion 12b on the left side wall of the second divided body 11b is pressed from the right against the inner wall of the intake port 2. The coefficient of friction of the first anti-slip portion 12a and the second anti-slip portion 12b is greater than that of the skin material 24, so they come into close contact with the inner wall of the intake port 2. This fixes the first divided body 11a and the second divided body 11b in the intake port 2 in a state where they cannot be removed.

When removing the push-in cap 10a from the intake port 2, the lever 36c of the toggle clamp 36 is rotated to move the stroke shaft 36d to the right. This causes the tip of the stroke shaft 36d to move away from the locking block 37. As a result, the frictional force between the first anti-slip portion 12a and the inner wall of the intake port 2 is reduced, and the frictional force between the second anti-slip portion 12b and the inner wall of the intake port 2 is also reduced.

Next, the operator grasps the handle 35 and pulls the first and second divisions 11a and 11b forward in the opening direction. This removes the push-in cap 10a from the intake port 2.

5. Effects of the Present Embodiment Next, the effects of the present embodiment will be described. The push-in cap 10a according to the present embodiment is fitted into the intake port 2 of the moving body 1. The push-in cap 10a includes a cap body 11 and an anti-slip portion 12. The cap body 11 closes the intake port 2 when fitted into the intake port 2. The cap body 11 also includes a cap outer surface 11c that faces the inner wall of the intake port 2. The anti-slip portion 12 is disposed on at least a part of the cap outer surface 11c of the cap body 11. The anti-slip portion 12 is formed of a material having a larger friction coefficient than the cap outer surface 11c, and abuts against the inner wall of the intake port 2. The anti-slip portion 12 abuts against the inner wall of the intake port 2, thereby holding the push-in cap 10a in a state where it is prevented from being removed from the intake port 2. This makes it possible to prevent the push-in cap 10a from falling off the intake port 2.

The cap body 11 comprises an elastically deformable hard elastic material 22 and soft elastic material 23, and a skin material 24 that covers the hard elastic material 22 and the soft elastic material 23. The skin material 24 constitutes the cap outer surface 11c. The hard elastic material 22 or the soft elastic material 23 elastically deforms, allowing the outer shape of the push-in cap 10a to deform in accordance with the shape of the inner wall of the intake port 2. This makes it easier to fit the push-in cap 10a into the intake port 2 and prevents the push-in cap 10a from falling off the intake port 2.

The soft elastic material 23 is located on the inner wall side of the intake port 2 when the cap body 11 is fitted inside the intake port 2. The hard elastic material 22 is located on the opposite side to the inner wall of the intake port 2 when the cap body 11 is fitted inside the intake port 2. The hard elastic material 22 has a higher elastic modulus than the soft elastic material 23. The soft elastic material 23 is easily deformed, so that the outer shape of the push-in cap 10a can be changed to correspond to the inner shape of the intake port 2. As a result, the insertion force required to insert the push-in cap 10a into the intake port 2 can be reduced. In addition, it is possible to accommodate variations in the manufacturing dimensions of the intake port 2. Furthermore, since the outer shape of the push-in cap 10a is maintained by the hard elastic material 22, the friction force between the anti-slip portion 12 and the inner wall of the intake port 2 can be maintained. This makes it possible to prevent the push-in cap 10a from falling off the intake port 2.

The cap body 11 comprises a first divided body 11a and a second divided body 11b, each of which comprises a divided body inner surface 11e where the first divided body 11a and the second divided body 11b face each other, and a divided body outer surface 11d where the first divided body 11a and the second divided body 11b face the inner wall of the intake port 2, and a non-slip portion 12 is disposed on the divided body outer surface 11d. This improves workability compared to when one large push-in cap is fitted into the intake port 2. Also, the first divided body 11a and the second divided body 11b are prevented from falling off the intake port 2.

Furthermore, a toggle clamp 36 is provided that presses the first divided body 11a and the second divided body 11b against the inner wall of the intake port 2 by pressing the first divided body 11a and the second divided body 11b in a direction different from the intake port 2. This allows the first divided body 11a and the second divided body 11b to be firmly pressed against the inner wall of the intake port 2, further preventing the push-in cap 10a from falling off the intake port 2.

When the first divided body 11a and the second divided body 11b are pressed by the toggle clamp 36, the first anti-slip portion 12a and the second anti-slip portion 12b are disposed on at least the surface of the cap outer surface 11c that is pressed against the inner wall of the intake port 2 by the toggle clamp 36. This further prevents the push-in cap 10a from falling off the intake port 2.

When the first and second divided bodies 11a and 11b are pressed by the toggle clamp 36, the anti-slip portion 12 is disposed on at least the surface of the divided body outer surface 11d that is pressed against the inner wall of the intake port 2 by the pressing device. This further prevents the push-in cap 10a from falling off the intake port 2.

Furthermore, a flexible hinge 26 is provided that connects the first divided body 11a and the second divided body 11b, and the hinge 26 is disposed on the rear surface of the cap outer surface 11c in the opening direction of the intake port 2, straddling adjacent edges of the first divided body 11a and the second divided body 11b. As a result, when inserting the push-in cap 10a into the intake port 2, the positioning of the first divided body 11a and the second divided body 11b can be easily adjusted, improving the efficiency of the assembly work of the push-in cap 10a.

The toggle clamp 36 is fixed to a metal front plate 31 that is fixed to the cap body 11. When the toggle clamp 36 presses against the first division 11a and the second division 11b, a relatively large force is applied to the toggle clamp 36. Because the toggle clamp 36 is fixed to the metal front plate 31, the force applied by the toggle clamp 36 to the first division 11a and the second division 11b can be prevented from being reduced. This further prevents the push-in cap 10a from falling off the intake port 2.

The inner wall of the intake port 2 is tapered to become narrower as it approaches the back of the intake port 2 in the opening direction. When the push-in cap 10a is fitted into an intake port 2 of this shape, the push-in cap 10a is relatively easy to remove. In such cases, the push-in cap 10a of this embodiment is effective.

This embodiment also includes a push-in cap 10a that is fitted into the intake port 2 of a moving body 1, which closes the intake port 2 when fitted into the intake port 2, a cap body 11 that includes a first divided body 11a and a second divided body 11b, and a toggle clamp 36 that presses the first divided body 11a and the second divided body 11b in different directions to press the first divided body 11a and the second divided body 11b against the inner wall of the intake port 2. The toggle clamp 36 presses the first divided body 11a and the second divided body 11b against the inner wall of the intake port 2, thereby preventing the push-in cap 10a from falling off the intake port 2.

This embodiment is a method for assembling a push-in cap 10a, and includes the steps of inserting the first and second divided bodies 11a and 11b into the intake port 2 with the outer surfaces 11d of the first and second divided bodies 11b positioned rearward in the direction of the intake port 2 and the inner surfaces 11e of the first and second divided bodies 11a and 11b positioned forward in the direction of the intake port 2, and pushing the ends of the first and second divided bodies 11a and 11b of the push-in cap 10a inserted into the intake port 2 that are positioned forward in the direction of the intake port 2 rearward in the direction of the intake port, and abutting the ends of the first and second divided bodies 11a and 11b on the intake port 2 side against the inner wall of the intake port 2, thereby attaching the push-in cap 10a to the intake port 2 in a state where it cannot be removed.

The above-described method of assembling the push-in cap 10a can prevent the push-in cap 10a from falling off the intake port 2.

The first and second divided bodies 11a and 11b have guide slopes 25 formed at the rear position in the opening direction of the divided body outer surface 11d, which are narrower toward the rear in the opening direction, and the process of inserting the first and second divided bodies 11a and 11b into the intake port 2 includes a process of inserting the push-in cap 10a into the intake port 2 while bringing the guide slopes 25 into contact with the opening edge of the intake port 2.

When attempting to insert the first and second divisions 11a and 11b into the intake port 2 from the front in the opening direction, the first and second divisions 11a and 11b make it difficult to see the opening edge of the intake port 2. Therefore, by bringing the guide slopes 25 formed on the first and second divisions 11a and 11b into contact with the opening edge of the intake port 2, the first and second divisions 11a and 11b can be easily inserted into the intake port 2.

After the process of pushing the ends of the first division 11a and the second division 11b located at the front in the opening direction rearward in the opening direction, the inner faces 11e of the first division 11a and the second division 11b are butted against each other to prevent the first division 11a and the second division 11b from moving in a direction that would cause them to fall out of the intake port 2. This further prevents the first division 11a and the second division 11b from falling out of the intake port 2.

After pushing the first division 11a and the second division 11b backward in the opening direction, the process includes pressing the first division 11a and the second division 11b against the inner wall of the intake port 2. This further prevents the push-in cap 10a from falling off the intake port 2.

This embodiment is a method for assembling a push-in cap 10a, which fits the push-in cap 10a into the intake port 2, and includes a process of inserting the first divided body 11a and the second divided body 11b into the intake port 2 in a state in which the ends of the first divided body 11a and the second divided body 11b that are located on the inner wall side of the intake port 2 are arranged on the rear side in the opening direction, and the ends of the first divided body 11a and the second divided body 11b that are located opposite the inner wall of the intake port 2 are arranged on the front side in the opening direction. and a process of pushing the ends of the first divided body 11a and the second divided body 11b inserted into the intake port 2 that are located at the front in the opening direction backward in the opening direction.

The above-described method of assembling the push-in cap 10a can prevent the push-in cap 10a from falling off the intake port 2.

(Embodiment 2)
Next, a second embodiment will be described with reference to Fig. 11. In the push-in cap 10b according to this embodiment, a locking hole 37a is formed on the right side surface of the locking block 37 facing leftward. The locking hole 37a is a bottomed hole having a bottom portion 37b (an example of a locking portion). The inner surface of the locking hole 37a is an example of a hook portion and a second hook portion.

When the lever 36c of the toggle clamp 36 is rotated and the stroke shaft 36d moves to the left, the tip of the stroke shaft 36d is inserted into the locking hole 37a. Furthermore, the tip of the stroke shaft 36d presses the bottom 37b of the locking hole 37a to the right. As a result, the left side of the second divided body 11b is pressed against the inner wall of the intake port 2, and as a reaction, the right side of the first divided body 11a is pressed against the inner wall of the intake port 2.

When the stroke shaft 36d is inserted into the locking hole 37a, the side of the stroke shaft 36d hooks onto the inner side of the locking hole 37a from the rear in the opening direction. The stroke shaft 36d is an example of a first hook portion.

Note that, among the symbols used in the second and subsequent embodiments, those that are the same as those used in the previous embodiments represent the same components, etc., as in the previous embodiments, unless otherwise specified.

In the push-in cap 10b according to this embodiment, the toggle clamp 36 is formed long in the left-right direction and includes a stroke shaft 36d that can move in the left-right direction. The locking block 37 includes a bottom 37b of the locking hole 37a against which the end of the stroke shaft 36d abuts in the left-right direction, and an inner surface of the locking hole 37a against which the side of the stroke shaft 36d hooks from the rear in the opening direction. When the end of the stroke shaft 36d abuts against the bottom 37b of the locking hole 37a, the first divided body 11a and the second divided body 11b are pressed against the inner wall of the intake port 2. This further prevents the push-in cap 10b from falling off the intake port 2. In addition, when the side of the stroke shaft 36d hooks on the inner surface of the locking hole 37a, the first divided body 11a and the second divided body 11b near the center in the longitudinal direction can be prevented from moving forward in the opening direction. This further prevents the push-in cap 10b from falling off the intake port 2.

Furthermore, the first divided body 11a is provided with a stroke shaft 36d, and the second divided body 11b is provided with an inner surface of a locking hole 37a that engages with the side of the stroke shaft 36d when the cap body 11 is fitted inside the intake port 2. The side of the stroke shaft 36d and the inner surface of the locking hole 37a are hooked together, thereby preventing the first divided body 11a and the second divided body 11b from moving in a direction that would cause them to fall off the intake port 2.

However, the configuration of the second hook portion is not limited to the inner surface of the locking hole 37a, and the side surface of the stroke shaft 36d may be formed in a plate shape that can be engaged from the rear or front.

This makes it possible to reduce the insertion force required when inserting the push-in cap 10c into the intake port 2.

Although not shown in detail, a hard elastic material 22 may be arranged above and below the core material 21. In this case, the frictional force between the first anti-slip portion 12a and the second anti-slip portion 12b and the inner wall of the intake port 2 can be maintained, so that the push-in cap 10c can be prevented from coming off the intake port 2.

However, the elastic modulus of the elastic material is not limited to the above, and an elastic material with any elastic modulus can be used.

(Embodiment 4)
Next, a fourth embodiment will be described with reference to Figures 13 to 15. In a push-in cap 10d according to this embodiment, a third anti-slip portion 12c is disposed at a position near the front end of the push-in cap 10 in a portion facing the inner surface of the intake port 2.

As shown in FIG. 13, the third anti-slip portion 12c is formed on the upper surface of the upper wall 14 of the first division 11a near the front end and has a shape elongated in the left-right direction, and is also formed on the upper surface of the upper wall 14 of the second division 11b near the front end. In the portion of the upper surface of the upper wall 14 of the first division 11a that is rearward of the third anti-slip portion 12c in the front-to-rear direction, the cap outer surface 11c is exposed and faces the inner wall of the intake port 2.
