JP2012-21642A

By the way, when removing the oil filler cap (hereinafter simply referred to as the cap) to replace the engine oil, it is necessary to temporarily place the cap removed from the oil filler port in another location. In the case of a filler cap for a fuel filler as in Patent Document 1, the filler cap for the fuel filler is basically placed only at a specific location such as a gas station, so the filler cap for the fuel filler is placed nearby. It is provided. However, the engine oil is often changed by the driver himself, and there are no particular restrictions on the location. For this reason, the cap is often placed in a suitable location outside the engine compartment. The cap itself is a relatively small component, so if you leave it in the wrong place, you may lose it or forget to close it. If the cap is not attached to the fuel filler port, a large amount of oil will leak outside.

The technology disclosed herein has been developed in view of these points, and its purpose is to make it possible to attach and detach the oil filler cap, and to prevent forgetting to close the oil filler cap. The objective is to provide a detachable tool.

In order to solve the above problems, the technology disclosed herein provides an oil filler cap that has a fastening part that is fastened to an engine oil filler port, and a knob part that extends in a direction perpendicular to the rotational axis direction of the fastening part. An operating part that is rotatably operated by an operator, and an operating part that is provided integrally with the operating part and that engages with the knob part when installing and removing the oil filler cap. The oil filler cap is configured to include an engaging portion and a placement portion provided on the operation portion and on which the oil filler cap removed from the oil filler port is placed.

According to this configuration, the oil filler cap itself can be placed on the attachment/detachment tool, and the oil filler cap and the attachment/detachment tool can always be present as a set. Therefore, it is easy for the operator to recognize the presence of the oil filler cap, and it is possible to prevent the operator from forgetting to close the oil filler cap.

In one embodiment of the oil filler cap attaching/detaching tool, the operating portion has a cylindrical shape with an opening provided at one end in the axial direction of the cylinder, and the engaging portion is located at one end of the operating portion in the axial direction of the cylinder. The mounting portion is provided on the other end side and includes the opening.

According to this configuration, a part of the oil filler cap can be stored within the opening, and a compact storage state can be realized. Further, by providing the oil filler cap on the opposite side to the engaging portion, it becomes easier for the operator to recognize the presence of the oil filler cap, and it is possible to more effectively prevent forgetting to close the oil filler cap.

In the embodiment, the engaging portion includes a pair of legs extending in the cylinder axis direction and a first predetermined direction perpendicular to the cylinder axis direction, and the pair of legs extend in the cylinder axis direction and in a first predetermined direction perpendicular to the cylinder axis direction. The structure may be such that they are spaced apart from each other in a second predetermined direction perpendicular to both the axial direction and the first predetermined direction.

According to this configuration, the attachment/detachment tool can be stood up with the mounting portion facing upward. Thereby, the degree of freedom in the placement of the attachment/detachment tool itself can be improved. Furthermore, since the placing portion is located at the top, it becomes easier for the operator to recognize the presence of the oil filler cap. As a result, forgetting to close the oil filler cap can be more effectively suppressed.

In an embodiment in which the engaging portion is constituted by a pair of leg portions, a non-slip portion is formed at one of both end portions of each of the leg portions in the first predetermined direction, and the non-slip portion is When viewed from the direction of the cylinder axis, the legs may be formed on each of the legs so as to be point symmetrical about the cylinder axis.

That is, when removing the oil filler cap from the oil filler port, it is necessary to apply appropriate rotational force to the knob, so the anti-slip part and the knob are brought into contact. Since the anti-slip portions are arranged point-symmetrically, each anti-slip portion of the pair of legs can be brought into contact with the knob portion. Thereby, the oil filler cap can be easily removed.

On the other hand, when attaching the oil filler cap to the fuel filler port, it is necessary to properly screw the fastening part into the threaded part of the filler port, so the position of the oil filler cap must be adjusted so that the oil filler cap can be displaced appropriately. Preferably adjustable. Therefore, when attaching the oil filler cap to the oil filler port, the side of the engaging portion that does not have the anti-slip portion is brought into contact with the knob portion. This allows the oil filler cap to be properly attached to the oil filler port. As a result, forgetting to close the oil filler cap can be more effectively suppressed.

In the embodiment, the operating section has a bottomed cylindrical shape with a bottom formed on the other end side in the axial direction of the cylinder, and another rotary tool is engaged with the bottom of the operating section. , an engagement hole for rotating the operating section by rotation of the rotary tool may be provided.

That is, since there is a gap between the fastening portion of the oil filler cap and the oil filler port, a small amount of engine oil enters into this gap. When this engine oil solidifies, simply gripping the operation part and applying rotational force will not provide sufficient torque, making it difficult to remove the oil filler cap. Therefore, by providing an engagement hole that can be engaged with a rotary tool and applying rotational torque using the rotary tool, the oil filler cap can be easily removed even if engine oil is stuck. be able to. Further, even when the operator cannot grasp the operation part due to the narrow space, the oil filler cap can be easily removed. Thereby, workability can be improved.

In the above embodiment, the operation section may have a polygonal shape having an odd number of corners of five or more angles when viewed from the direction of the cylinder axis.

That is, when the operating section has an even number of corners, when all five fingers are placed on the operating section, the fingers tend to lean to one side. On the other hand, if the operating section has an odd number of corners, it becomes easier to place the fingers symmetrically on the corner. As a result, it becomes easier to input rotational torque to the operating section, and work efficiency can be improved.

In the embodiment, the mounting portion may be configured such that the oil filler cap is placed in a state where the fastening portion of the oil filler cap is located within the opening.

According to this configuration, the oil filler cap can be placed with the knob portion located on the upper side, and it is possible to prevent the operator's hands from getting dirty as much as possible. Moreover, the mounting state of the oil filler cap on the mounting portion can also be stabilized.

As described above, according to the technology disclosed herein, it is possible to attach and detach the oil filler cap, and it is possible to prevent forgetting to close the oil filler cap.

Hereinafter, exemplary embodiments will be described in detail based on the drawings.

FIG. 1 shows an attachment/detachment tool 1 according to this embodiment. This attachment/detachment tool 1 is used to attach/detach an oil filler cap 100 (see FIGS. 6 to 9; hereinafter simply referred to as cap 100) attached to an engine oil filler port to remove it from the filler port and attach it to the filler port. It's a tool. As shown in FIGS. 7 and 8, the cap 100 includes a disk-shaped cap body 101 that closes the fuel filler port, a fastening portion 102 that is provided integrally with the cap body 101 and is fastened to the fuel filler port, and a cap body. The cap body 101 has a knob portion 103 provided integrally with the cap body 101 on the opposite side of the fastening portion 102 . The knob portion 103 extends in a direction perpendicular to the rotation axis direction of the fastening portion 102 . When removing or attaching the cap 100 to the fuel filler port, torque is input to the knob portion 103 to rotate the cap 100.

As shown in FIG. 1, the attachment/detachment tool 1 includes an operating section 10 for an operator to rotate the attachment/detachment tool 1, and a pair of leg sections 20 that engage with a knob section 103 when attaching and removing the cap 100. Equipped with. The operating section 10 and the leg section 20 are integrated. The attachment/detachment tool 1 is made of resin, for example, polypropylene.

As shown in FIGS. 1 to 3, the operating portion 10 has a heptagonal outer shape and a bottomed rectangular tube shape having a bottom portion 11. As shown in FIGS. The seven surface portions 13 located between the seven corner portions 12 of the operating portion 10 each have a curved shape recessed in an arc shape toward the cylinder axis X. As shown in FIGS. 4 and 5, a portion of each surface portion 13 close to the bottom 11 is inclined in a direction approaching the cylinder axis X so as to reduce the internal cross-sectional area of the operating portion 10 toward the bottom 11. This is a reduction section 14. A portion of each surface portion 13 on one side in the cylinder axis direction (opposite side to the bottom portion 11) of the reduced portion 14 is a recessed portion 13a recessed toward the cylinder axis X. As will be described in detail later, the concave portion 13a is a portion where the operator's fingers are placed when the operator grips and operates the operating portion 10.

The operating portion 10 has an opening 15 formed at the end of the one side in the direction of the cylinder axis. The end portion of each corner portion 12 and each surface portion 13 on the one side in the direction of the cylinder axis serves as a peripheral edge portion 15a of the opening portion 15. As will be described in detail later, the opening 15 and its peripheral edge 15a constitute a placement section 16 on which the cap 100 removed from the fuel filler port is placed.

As shown in FIGS. 2, 3, and 8, the bottom portion 11 of the operating portion 10 is formed with a through hole 11a that penetrates in the axial direction of the cylinder. Specifically, the bottom portion 11 has a raised portion 11b that is raised on one side in the cylinder axis direction toward the cylinder axis X, and a through hole 11a is formed in the center of the raised portion 11b. The through hole 11a has a rectangular shape when viewed from the cylinder axis direction. The hole axis of the through hole 11a is coaxial with the cylindrical axis X of the operating section 10. Although details will be described later, the through hole 11a is a portion into which the rotary tool T is inserted when the operator rotates the operating portion 10 using the rotary tool T.

As shown in FIGS. 3 to 5, the pair of legs 20 is provided integrally with the bottom portion 11 on the other side of the operating portion 10 in the cylinder axis direction. The pair of leg portions 20 extend in the cylinder axis direction and in a first predetermined direction orthogonal to the cylinder axis direction. The pair of leg portions 20 are spaced apart from each other in a second predetermined direction orthogonal to both the cylinder axis direction and the first predetermined direction. As shown in FIG. 3, the pair of leg portions 20 are formed to be point symmetrical with respect to the cylinder axis X. Hereinafter, the configuration of the leg portion 20 will be described in detail, with the leg portion 20 located on one side in the second predetermined direction being referred to as the first leg portion 21 and the leg portion located on the other side being referred to as the second leg portion 22. Note that the leg portion 20 constitutes an engaging portion that engages with the knob portion 103.

The first leg portion 21 has a first slope portion 21a that slopes away from the second leg portion 22 toward the one side at an end portion on one side in the first predetermined direction. The first leg portion 21 has a second slope portion 21b that slopes away from the second leg portion 22 toward the other side at the other end in the first predetermined direction. The first inclined portion 21a is a portion that engages with the knob portion 103 when the cap 100 is removed, while the second inclined portion 21b is a portion that engages with the knob portion 103 when the cap 100 is attached.

As shown in FIG. 3, the end portion of the first inclined portion 21a on the one side in the first predetermined direction has a curved portion that is curved toward the opposite side from the second leg portion 22 in the second predetermined direction. A portion 21c is formed. A first anti-slip portion 21d consisting of a plurality of grooves is formed in the first inclined portion 21a of the first leg portion 21 and in its vicinity. The length of the first anti-slip portion 21d in the cylinder axis direction is approximately half the length of the first leg portion 21 in the cylinder axis direction.

As described above, the second leg portion 22 is formed to be point symmetrical to the first leg portion 21 with respect to the cylinder axis X. Therefore, the second leg portion 22 has a third slope portion 22a corresponding to the first slope portion 21a of the first leg portion 21 at the end portion on the other side in the first predetermined direction. Further, the second leg portion 22 has a fourth slope portion 22b corresponding to the second slope portion 21b of the first leg portion 21 at the end portion of the one side in the first predetermined direction. The third inclined portion 22a is a portion that engages with the knob portion 103 when the cap 100 is removed, while the fourth inclined portion 22b is a portion that engages with the knob portion 103 when the cap 100 is attached.

A curved portion 22c curved toward the opposite side of the first leg portion 21 in the second predetermined direction is formed at the other end of the third inclined portion 22a in the first predetermined direction. . A second anti-slip portion 22d consisting of a plurality of grooves is formed on the third inclined portion 22a of the second leg portion 22 and a portion near the third inclined portion 22a. The length of the second anti-slip portion 22d in the axial direction of the cylinder is approximately half the length of the second leg portion 22 in the axial direction of the cylinder, similarly to the first anti-slip portion 21d.

By configuring the first leg portion 21 and the second leg portion 22 as described above, the first non-slip portion 21d and the second non-slip portion 22d are centered around the cylinder axis X when viewed from the cylinder axis direction. The first leg portion 21 and the second leg portion 22 are formed so as to be symmetrical with respect to each other.

Next, examples of how to use the attachment/detachment tool 1 will be described with reference to Figures 6 to 13.

When removing the cap 100 from the fuel filler port using the attachment/detachment tool 1, make sure that the first non-slip portion 21d of the first leg portion 21 and the second non-slip portion 22d of the second leg portion 22 contact the knob portion 103. , engage each leg portion 21, 22 with the knob portion 103. From this state, the operator grasps the operating section 10 and rotates the knob section 103 in the direction of the arrow in FIG. 6 (usually counterclockwise). By rotating the cap 100 while gripping the operating portion 10, a larger rotational torque can be input to the cap 100 than when rotating the cap 100 by gripping the knob portion 103. Thereby, the cap 100 can be easily removed. Furthermore, since the first inclined part 21a and the third inclined part 22a are formed with curved parts 21c and 22c, respectively, the first inclined part 21a and the third inclined part 22a bend the reaction force from the knob part 103. It can be received at the parts 21c and 22c. This makes it difficult for the first inclined portion 21a and the third inclined portion 22a to deform, so that rotational torque can be appropriately input to the knob portion 103.

After removing the cap 100 from the fuel filler port, it is necessary to temporarily place the cap 100 in another location. In the attachment/detachment tool 1 of this embodiment, the operation part 10 is provided with a placement part 16 on which the cap 100 can be placed. As shown in FIGS. 7 and 8, the mounting section 16 is composed of an opening 15 of the operating section 10 and a peripheral edge 15a of the opening 15. As shown in FIGS. The mounting portion 16 can accommodate the fastening portion 102 of the cap 100 within the opening 15 . The cap main body 101 of the cap 100 is placed on the peripheral edge 15a of the placement portion 16. In this way, the mounting portion 16 is configured such that the cap 100 is placed with the fastening portion 102 of the cap 100 located within the opening 15. The operating section 10 is designed so that the length in the cylinder axis direction is longer than the length of the fastening part 102 in the rotation axis direction so that the fastening part 102 can be accommodated in the cylinder. More specifically, the distance from the opening 15 of the operating portion 10 to the one end of the raised portion 11b in the cylinder axis direction is configured to be longer than the length of the fastening portion 102 in the rotational axis direction. ing.

As shown in FIG. 9, the attachment/detachment tool 1 can be stood on the cylinder head cover E of the engine with the cap 100 placed thereon. Each of the legs 21 and 22 extends in the first predetermined direction, and the first leg 21 is provided with first and second inclined parts 21a and 21b, and the second leg 22 is provided with third and fourth inclined parts. Since the portions 22a and 22b are provided, the attachment/detachment tool 1 can be kept upright in a stable state. Further, for example, the area between the first and second leg parts 21 and 22 can be hooked onto a convex part of the engine room such as a bonnet hook or piping. Since parts are crowded in the engine room, when the device is hooked onto a convex portion of the engine room, the side surfaces of the first and second leg portions 21 and 22 and the operating portion 10 will be caught on nearby components. Thereby, the attachment/detachment tool 1 can be stably arranged. Further, since the cap 100 can be temporarily placed near the worker, the worker can easily recognize the presence of the cap 100, and can also prevent forgetting to close the cap 100.

When attaching the cap 100 to the fuel filler port after replacing the engine oil, the first and second leg portions 21 and 22 are engaged with the knob portion 103 while the fastening portion 102 of the cap 100 is applied to the fuel filler port. let At this time, as shown in FIG. 10, the legs 21 and 22 are connected so that the second inclined part 21b of the first leg part 21 and the fourth inclined part 22b of the second leg part 22 contact the knob part 103. The knob portion 103 is engaged. Since a non-slip portion is not formed in the second inclined portion 21b and the fourth inclined portion 22b, the cap 100 is likely to be displaced relative to the attachment/detachment tool 1 in a direction intersecting the rotation axis direction. This facilitates alignment of the threaded portion of the oil filler port and the fastening portion 102. That is, if the second inclined part 21b and the fourth inclined part 22b are provided with anti-slip parts, the cap 100 will be difficult to displace relative to the attachment/detachment tool 1, so that when the cap 100 is applied to the fuel filler port, If the threads of the fuel filler port and the threads of the fastening portion 102 do not match, the fastening portion 102 cannot be properly fastened. On the other hand, if the cap 100 can be displaced relative to the attachment/detachment tool 1, it becomes easier to match the threads of the oil filler port and the threads of the fastening portion 102.

Here, when the operator grasps and operates the operating section 10 both when removing and attaching the cap 100, the operator rotates the operating section 10 with his or her fingers hooked into the recesses 13a of each surface section 13. At this time, since the shape of the operation part 10 when viewed from the direction of the cylinder axis is an odd-numbered polygon of pentagon or more, more specifically, it is a heptagon, so that it is easy for the operator to put his/her finger on the operation part 10 so that the rotational torque can be applied to the operation part 10. It is in a state where it is easy to input.

That is, as shown in FIG. 11, if the shape of the operation part 10 when viewed from the cylindrical axis direction is a hexagon, when the operator places all of his fingers F on the surface part, it will move clockwise or counterclockwise. The position of the fingers is uneven. This makes it difficult for the operator to put his or her fingers on it.

On the other hand, as shown in FIG. 12, if the shape of the operation part 10 when viewed from the cylindrical axis direction is a heptagon, even if the operator places all of his fingers F on the surface part 13, the position of the fingers F will be in a clockwise position. There is no bias towards the rotational or counterclockwise side. Therefore, it becomes easy for the operator to put his or her finger on the rotational torque and input the rotational torque to the operation unit 10.

When removing the cap 100, engine oil may become stuck between the fastening portion 102 and the oil filler port, making it difficult to rotate the cap 100. At this time, there is a possibility that the cap 100 will not rotate if the operator simply holds and operates the operating section 10. On the other hand, in this embodiment, since the through hole 11a having the hole axis coaxial with the cylindrical axis X of the operating section 10 is provided, as shown in FIG. can be engaged. Thereby, the cap 100 can be rotated by inputting a larger rotational torque to the operating section 10 using the rotating tool T and rotating the operating section 10 by the rotation of the rotating tool T. In addition, even when the operator cannot grasp the operation part 10 because the space is too narrow for the operator to reach, the cap 100 can be easily removed. Although FIG. 13 illustrates a T-shaped rotary tool T that is manually rotated by an operator, the rotary tool T is not particularly limited as long as it can engage with the through hole 11a. For example, an electric rotary tool may be used.

Therefore, according to the present embodiment, the attachment/detachment tool 1 includes an operation section 10 that is rotatably operated by an operator, and a leg that is provided integrally with the operation section 10 and that engages with the knob section 103 when attaching and removing the cap 100. 20, and a placing part 16 provided on the operating part 10 and on which the cap 100 removed from the fuel filler port is placed. As a result, the cap 100 and the attachment/detachment tool 1 can always be present as a set, making it easier for the operator to recognize the presence of the cap 100 and preventing the operator from forgetting to close the cap 100.

In particular, the leg portion 20 includes a first leg portion 21 and a second leg portion 22 that extend in the cylinder axis direction of the operation unit 10 and a first predetermined direction perpendicular to the cylinder axis direction, respectively. The two leg portions 21 and 22 are spaced apart from each other in a second predetermined direction perpendicular to both the cylinder axis direction and the first predetermined direction. This allows the attachment/detachment tool to stand up with the placement portion 16 facing upward, making it easier for the operator to recognize the presence of the cap 100. As a result, forgetting to close the cap 100 can be more effectively suppressed. Moreover, the degree of freedom in the placement of the attachment/detachment tool 1 itself can be improved.

Further, in the present embodiment, the mounting portion 16 is configured such that the cap 100 is placed in a state where the fastening portion 102 of the cap 100 is located within the opening 15. Thereby, the cap 100 can be placed with the knob portion 103 located on the upper side, and it is possible to prevent the operator's hands from getting dirty as much as possible. Further, the state in which the cap 100 is placed on the placement portion 16 can also be stabilized.

Further, first and second anti-slip portions 21d and 22d are respectively formed on one of both end portions of the first and second leg portions 21 and 22 in the first predetermined direction. The stop portions 21d and 22d are formed on the first and second leg portions 21 and 22, respectively, so as to be point symmetrical about the cylinder axis X when viewed from the cylinder axis direction. Thereby, when removing the cap 100 from the fuel filler port, an appropriate rotational torque can be input to the cap 100 by bringing the first and second anti-slip parts 21d and 22d into contact with the knob part 103. On the other hand, when attaching the cap 100 to the fuel filler port, the cap 100 is attached by contacting the sides of the first and second leg sections 21 and 22 where the first and second anti-slip sections 21d and 22d are not provided with the knob section 103. can be appropriately displaced, thereby making it easy to attach the cap 100 to the fuel filler port.

Further, in this embodiment, the bottom 11 of the operating section 10 is provided with a through hole 11a for engaging another rotating tool T and rotating the operating section 10 by the rotation of the rotating tool T. . Thereby, even if engine oil is stuck between the fastening portion 102 and the oil filler port and a large rotational torque is required to remove the cap 100, the cap 100 can be easily removed.

The technology disclosed herein is not limited to the embodiments described above, and may be substituted without departing from the spirit of the claims.

For example, in the embodiment described above, the shape of the operating portion 10 when viewed from the cylinder axis direction was a heptagon. The shape is not limited to this, and may be a pentagon or a nonagon. However, if the number of corners is small, it will be difficult for the operator to place his or her fingers on it, and if the number of corners is large, the shape will become closer to a cylinder, making it difficult to input rotational torque to the operation unit 10, so a heptagonal shape is most preferable. .

Further, in the embodiment described above, the operating section 10 is made into a cylindrical shape, and the opening 15 of the operating section 10 and the peripheral edge 15a of the opening 15 are configured as the mounting section 16. However, the operation section 10 is not limited to this, and the mounting section 16 may be configured by making the operation section 10 into a prismatic shape and providing a recess in the upper surface portion to accommodate a part of the fastening section 102 of the cap 100.

The above-described embodiments are merely illustrative and should not be construed as limiting the scope of the present disclosure. The scope of the present disclosure is defined by the claims, and all modifications and changes that fall within the scope of equivalents of the claims are within the scope of the technology of the present disclosure.
