Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for refueling a vehicle.
The present invention relates to a fuel cap locking device for locking a fuel tank cap (hereinafter, referred to as a “fuel cap”).

[0002]

2. Description of the Related Art When a vehicle is supplied with fuel such as gasoline (hereinafter referred to as "gasoline") at a gas station, a fuel cap is removed from a filler port, gasoline is supplied, a fuel cap is attached to the filler port, and a lid is provided. The gas station serviceman will close the panel (the lid that covers the fuel filler). Therefore, the driver of the vehicle is not bothered by these operations.

[0003] In recent years, from the viewpoint of reducing the refueling cost and the like, a self-service type gas station in which the driver himself supplies gasoline to the vehicle has appeared. In this self-service gas station, all operations such as removal and installation of the fuel cap must be performed by the driver himself, which places a considerable burden on a driver unfamiliar with this operation. In particular, handling of the fuel cap removed from the fuel filler is troublesome.

That is, the driver must hold the fueling device (pipe) after grasping the fuel cap and removing it from the fuel filler port, so it is necessary to release the hand from the fuel cap. In this case, attach the fuel cap to the body (bonnet, etc.)
When placed on the vehicle, the fuel cap slides off the vehicle body, and gasoline adheres to the surface of the vehicle body.

Under these circumstances, as shown in FIG. 15, the fuel cap 10 is conventionally provided on the inner surface of the lid panel 103.
0 is formed, and the fuel cap 100 is attached to the chain-shaped or string-shaped tether 102 and the fixture 1.
04 connects to the inner surface 103a of the lid panel 103.

Specifically, the inner surface 1 of the lid panel 103
03a is formed with a pair of locking portions 113 protruding from the inner surface. The locking portion 113 locks the fuel cap 100 which is opened at the time of refueling and which has been removed from a refueling port (not shown). If the fuel cap 100 is locked to the locking portion 113 of the lid panel 103 at the time of refueling, a part of the vehicle body such as the bonnet may be
It does not get dirty with gasoline attached to it. When refueling is completed, the fuel cap 100 is detached from the locking portion 113, attached to the refueling port, and the lid panel 113 is closed.

An attachment 104 for attaching the other end of the tether 102 having one end attached to the fuel cap 100 to the lid panel 103 is made of resin and is connected to the tip of the tether 102 as shown in FIG. The grip body 106 includes a base portion 108 and a cylindrical portion 107 extending from the surface of the grip portion 106. The grip body 106 includes a round bar portion 110 inserted into the cylindrical portion 107 and a base portion 111. Tubular part 10
Reference numeral 7 has an annular step portion 107a formed on the outer peripheral surface thereof, and a slit (not shown) formed in a diametrical direction from an upper open end to a certain depth, so that the diameter can be expanded.

The other end of the tether 102 is connected to a lid panel 103
When attaching to the cylindrical portion 10 of the clip body 106,
7 is inserted into the through hole 103b of the lid panel 103. Thereafter, when the round bar portion 110 of the core 109 is inserted into the tubular portion 107 of the clip body 106, the tubular portion 107 expands in diameter, and the step portion 107a on the outer peripheral surface thereof becomes the lid panel 103.
Of the through hole 103b. As a result, the other end of the tether 102 is connected to the lid panel 1 by the fixture 104.
03 is attached. Therefore, the fuel cap 100 removed from the filler port is not lost.

[0009]

However, this conventional example has a problem in locking the fuel cap 100 to the lid panel 103. In vehicles (especially passenger cars), it is difficult to make the width of the interior space slightly larger (wider).
Since the width of the vehicle is determined by standards or the like, the only way to increase the width of the indoor space is to reduce the thickness of the side wall of the body while considering safety and the like. However, when the locking portion 113 is formed on the lid panel 103, it is necessary to take measures such as increasing the thickness of the side wall of the body, which goes against the above requirement.

The conventional example also has a problem in attaching the tether 102 to the lid panel 103. Since the round bar portion 110 of the core 109 of the fixture 104 is forcibly inserted into the cylindrical portion 107 of the clip body 106,
It may come off from the cylindrical portion 107 due to a tensile force applied to the tether 102 during refueling. The core 109 is a small part, and it is not easy to find when the core 109 comes off the clip body 106. The core 109 is the clip body 106
When the clip body 106 exits, the clip body 106
3, the other end of the tether 102 comes off the lid panel 103.

The present invention has been made in view of the above circumstances, and provides a fuel cap locking device which can lock a fuel cap without forming a locking portion for locking a fuel cap on a part of a vehicle body such as a lid panel. It was done for the purpose of doing.

[0012]

Means for Solving the Problems As a result of earnest studies, the present inventor has come up with the idea that the locking portion of the fuel cap is locked not by a part of the vehicle body such as a lid panel but by the fuel cap locking tool itself. Thus, the present invention has been completed.

That is, the present invention relates to a fuel cap locking device for locking a fuel cap when refueling a vehicle, comprising: a cap holding portion for holding the fuel cap; A tether, a vehicle body mounting portion for attaching the tip end of the tether to the vehicle body, one formed on the cap holding portion side of the cap holding portion or the tether, and one formed on the vehicle body mounting portion side of the vehicle body mounting portion or the tether. And a detachable member comprising one and the other detachable.

According to the present invention, the fuel cap held by the cap holding portion can be locked to a part of the fuel cap locking member, that is, to the vehicle body mounting portion or the vehicle body mounting portion side of the tether. As a result, processing for forming a locking portion for locking the fuel cap on a part of the vehicle body such as a lid panel becomes unnecessary, and
When determining the thickness of the body, it is not necessary to consider the size and height of the locking portion for the fuel cap locking tool.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cap holding portion of a fuel cap locking device of the present invention holds a fuel cap. The cap holding portion may be, for example, ring-shaped. By making the inner diameter of the ring-shaped cap holding portion larger than the outer diameter of the leg portion of the fuel cap or fitting the cap holding portion to the corner of the head of the fuel cap, the fuel cap is It is desirable to be able to rotate. With this configuration, the rotation of the fuel cap is not hindered by the cap holding portion when the fuel cap is removed from the filler port and when the fuel cap is attached to the filler port.

The tether of the fuel cap locking device extends from the cap holding portion and is bendable and string-shaped. Tether,
The cap holding portion can extend from one of the pair of end surfaces or the outer peripheral surface. When the tether extends from the outer peripheral surface of the cap holding portion, the cap holding portion and the tether are located on the same plane, whereby the thickness (height) of the fuel cap locking member can be reduced. If the cap holder is ring-shaped, the tether can extend from the cap holder at any angle. However, considering the coupling strength of the tether to the cap holding portion and the like, it is desirable that the tether extends so that its extension line becomes the chord of the ring-shaped cap holding portion. However, the tether can be extended from the cap holding portion in the diameter direction. It is desirable that the thickness and length of the tether be such that the tether can be easily bent when one of the detachable members provided on the cap holding portion or the like is attached to or detached from the other provided on the vehicle body attaching portion or the like.

The tip of the tether is attached to the vehicle body at the vehicle body mounting portion of the fuel cap locking device. The vehicle body is, for example, a lid panel that is opened to remove a fuel cap from a fuel filler port during refueling, or a part of a body that is exposed when the lid panel is opened. The vehicle body attachment portion can be formed integrally with the tether, or can be formed separately from the tether. When configuring the body mounting part integrally with the tether,
The vehicle body mounting portion includes a base portion having a flat contact surface that forms a part of the tether, a tubular portion protruding from the contact surface, and an expandable cylindrical portion, and a tubular portion inserted into the tubular portion to expand the tubular portion. The clip can be constituted by a core having a diameter and a center to be engaged with an edge of a through hole of a vehicle body. By doing so, the structures of the tip end portion of the tether and the vehicle body attaching portion become compact.

Further, the center core can be connected to the tip of the tether by a U-shaped connecting portion. This prevents the core from being lost even when the core once inserted into the cylindrical portion of the clip body comes out of the cylindrical portion, and also prevents the cap holding portion, the tether, and the vehicle body mounting portion from being lost. , And the detachable member can be integrally formed of a soft resin or the like.

Further, an engaging portion is formed on the outer peripheral surface of the center core, and an engaged portion with which the engaging portion is engaged is formed on the inner peripheral surface of the cylindrical portion.
The core can be held by the tubular part in a state where it is inserted halfway into the tubular part. In this way, even when the tubular portion and the core are not connected, the core can be prevented from being lost, and even when the tubular portion and the core are connected, the core is at the tip of the tether. It can be prevented from hanging from and interfering with surrounding members. When transporting and managing the fuel cap locking device, the end of the base of the core and the locked portion may be connected by a connecting piece, and the connecting piece may be cut off when used. In this case, the hanging of the core can be prevented without providing a means for holding the core partially inserted into the clip body as described above.

One of the attachment / detachment members of the fuel cap locking member is
It can be formed on the cap holder or on the cap holder side of the tether. When one of the detachable members is formed on the cap holding portion, its formation position depends on the position where the tether extends, whether the lid panel and the fuel cap are on the left side or the right side of the vehicle body, etc. It can be selected as appropriate. That is, when the lid panel or the like is on the left side of the vehicle body, the fuel cap locking device is curved in an inverted C shape as a whole, and when the lid panel or the like is on the left side surface of the vehicle body, the fuel cap locking member is formed as a whole in a C shape. It is because it is curved. On the other hand, the other of the attachment / detachment members can be formed on the vehicle body attachment portion or on the vehicle body attachment portion side of the tether. If one of the detachable members is formed on the cap holding portion and the other is formed on the vehicle body attaching portion, the length of the tether can be reduced.

The specific structure of the attaching / detaching member is such that it is easy to lock the cap holding portion in the vicinity of the vehicle body mounting portion by bending the tether, and the locking is not easily released once the locking is performed. Can be For example, one of the detachable members
The cap holding portion may be formed to protrude in the radial direction and / or the axial direction, and the other may be formed on the surface of the tether in the vicinity of the mounting portion opposite to the surface facing the lid panel. One of the attachment / detachment members is used to improve the ease of attachment / detachment to / from the other or to allow the fuel cap locking device to be shared when the lid panel and the fuel cap are on either the left or right side of the vehicle body. A plurality may be provided on the cap holder.

When the fuel cap locking member is not used, the cap holding portion, the tether, the vehicle body mounting portion and the detachable member are located within the plane where the ring-shaped cap retaining portion exists. It is desirable to configure so that the member exists. This facilitates the transportation and storage of the fuel cap locking device, and also facilitates the formation of the fuel cap locking device by injection molding or the like.

This fuel cap locking device is used for a passenger car having a lid panel 40 and a fuel cap 45 provided on the left side surface of the vehicle body as shown in FIG.
Hereinafter, each element will be described.

As shown in FIGS. 1 and 2, the cap holding portion 11 has a ring shape as a whole and a substantially rectangular cross section. An annular step 12 is formed on the inner peripheral surface of the cap holding portion 11 at the intermediate portion in the height direction. In FIG. 2, the inner diameter on the lower end surface side is smaller than the inner diameter on the upper end surface side. The inner diameter of the cap holding portion 11 is the fuel cap 4 shown in FIG.
5 is slightly smaller than the outer diameter of the head 46, so that the fuel cap 45 is rotatable within the cap holder 11.

As shown in FIG. 1, the tether 15 extends from the outer peripheral surface of the cap holder 11 at an angle such that an extension of the tether 15 forms the chord 15a of the cap holder 11.
A line connecting the extension point 16 of the tether 15 from the cap holding portion 11 to the center O of the cap holding portion 11;
And a line connecting the center O of the cap holding portion 11 forms a substantially right angle. The tether 15 extends in a plane (the paper surface of FIG. 1) in which the cap holding portion 11 is present, and the base end portion and the intermediate portion 17 close to the cap holding portion 11 are circular or rectangular in cross section, so that bending in any direction is possible. And easier. The distal end portion 18 of the tether 15 provided with the vehicle body attachment portion 33 described later has a flat cross section that is wider than other portions as shown in FIGS.
Extends in a plane substantially perpendicular to the plane in which. At the flat tip portion 18 of the tether 15, a middle core 28 is provided at the tip,
The clip body 20 is formed at a portion slightly retreated from the front end, and the locked portion 34 is formed at a portion further retreated from the front end. Next, these will be described.

As shown in FIGS. 3 and 5, the clip main body 20 erected on one surface (abutting surface) 18a of the distal end portion 18 of the tether 11 is connected to the base 2 composed of the distal end portion 18 of the tether 11.
1 and a cylindrical portion 23. A slit 24 is formed in the cylindrical portion 23 in the diametric direction from the opening end on the front end (lower end in FIG. 5) side to the middle, so that the front end side of the cylindrical portion 23 can be expanded in diameter. A plurality of annular projections 25 are formed on the outer peripheral surface of the cylindrical portion 23, and a large-diameter portion 26 a having an annular groove 26 b on the inner peripheral surface from the base 21 side on the inner peripheral surface;
6c and the conical portion 26d are formed continuously.

The core 28 comprises a base 29 and a round bar 30. The round bar portion 30 has a length corresponding to the sum of the thickness of the base portion 21 of the clip body 20 and the length of the cylindrical portion 23. The outer diameter of the round bar portion 30 is substantially equal to the inner diameter of the middle diameter portion 26c of the cylindrical portion 23, and two annular projections 31 are formed on the outer peripheral surface so as to be separated in the axial direction. The core 28 is connected to the distal end portion 18 of the tether 15 by a connecting portion 32 having a semicircular shape at the base portion 29 and having a smaller thickness than the base portion 29. The base 21 of the clip body 20 and the base 29 of the core 28 are 90 to 1
Make 80 degrees. The clip body 20 and the core 28 constitute a vehicle body attachment portion 33.

Next, the attachment of the tip end portion 18 of the tether 15 to the lid panel 40 by the vehicle body attachment portion 33 will be described with reference to FIGS.

When this fuel cap lock is not used for locking the fuel cap 45, as shown in FIG.
The clip is handled in a state where the middle core 28 of the vehicle body attachment portion 33 is inserted halfway into the clip body 20. In this state, the round bar 30
Has reached only the conical portion 26d of the cylindrical portion 23, and the diameter of the cylindrical portion 23 has hardly increased. Further, the annular protrusion 31 near the tip of the round bar portion 30 is
Is engaged with the annular groove 26b of the large-diameter portion 26a, thereby preventing the center core 28 from falling off from the clip body 23.

The lid panel 40 shown in FIGS. 11 and 12
Is released, and the clip body 20 is inserted into the through-hole 42 of the mounting portion 41 formed on the inner surface thereof as shown in FIG. 7, and then the round bar portion 30 of the core 28 is pushed into the tubular portion 23. Then, the cylindrical portion 23 expands in diameter as the round bar portion 30 is inserted,
The step 25 on the outer peripheral surface of the cylindrical portion 23 is engaged with the edge of the through hole 42. Thereby, the tip portion 18 of the tether 15 is attached to the inner surface of the lid panel 40.

On the other hand, as shown in FIG.
The cap holding portion 11 of the fuel cap locking device 10 is mounted on a step 46 a at the lower end edge of the head 46 of the resin fuel cap 45, and the fuel cap 45 connects the male thread of the leg 47 to the female thread of the fuel filler port 48. Is screwed into. Lid panel 4
0 is closed.

Next, locking of the cap holding portion 11 to the tether 15 by the detachable member 35 during refueling will be described.

As shown in FIG. 1, a locking portion 13 is formed at a predetermined portion on the circumference of the cap holding portion 11.
The locking portion 13 has a U-shaped portion 13 a protruding radially outward from the outer peripheral surface of the cap holding portion 11, and extends in the axial direction of the cap holding portion 11 from the middle thereof, and has a tip bent inward in the radial direction. And an L-shaped portion 13b. Also, as shown in FIGS.
8 has a U-shape, extends in the same direction as the extension direction of the distal end portion 18 of the tether 15, and projects in the thickness direction of the distal end portion 18. Locking part 1
The attachment / detachment member 35 is constituted by the 3 and the locked portion 34.

At the time of refueling, the lid panel 40 is opened leftward in FIG. 11 (clockwise in FIG. 12), and the fuel cap 45 is removed from the refueling port 48. At this time, since the cap holding unit 11 holds the fuel cap 45 in a rotatable manner, the rotation of the fuel cap 45 is not hindered by the cap holding unit 11.

After the fuel cap 45 is removed from the fuel supply port 48, the tether 15 is bent and the locking portion 13 of the cap holding portion 11 is moved toward the locked portion 34 of the tip 18 of the tether 15. In this embodiment, as shown in FIG. 11, the tip 18 of the tether 15 is attached to a lid panel 40 that opens to the left, and the fuel cap 45 is attached to the lid panel 4.
Since it is located to the right of 0, the tether 15 is curved in an inverted C-shape. At this time, the middle portion of the tether 15 has a rectangular cross-section, so that it is easy to bend.

When the cap holder 11 is moved closer to the tip 18 of the tether 15, the L-shaped portion 13b of the cap holder 11 is moved to the tip of the tether 15, as shown in FIGS. 18 to be locked. Since the L-shaped portion 13b protrudes from the cap holding portion 11 in the radial direction and the axial direction, the L-shaped portion 13b can be easily locked to the locked portion 34 from the near side. At this time, as shown by the two-dot chain line in FIG.
7 extends to the near side. The fuel cap 45 is attached to the leg 4
Since the head 46 having a length (thickness) smaller than that of the head 7 is located on the lid panel 40 side, there is no fear that the head 46 and the lid panel 40 interfere with each other. In addition, fuel cap 4
Since the center of gravity of the leg 5 is located at the leg 47, the tip of the leg 47 is vertically lowered below the head 46 in a stable state, and does not come off the cap holding portion 11 by a small amount. Since the fuel cap 45 is separated from the body,
The body is not contaminated by gasoline attached to the fuel cap 45.

When the refueling is completed, the L-shaped portion 13b of the locking portion 13 is removed from the locked portion 34, and the cap holding portion 11, that is, the fuel cap 45 is moved toward the refueling port 48, so that the fuel cap 45 After attaching to the filler port 48,
The lid panel 40 is closed.

According to this embodiment, the following effects can be obtained.

First, one of the attachment / detachment members 13 is connected to the cap holder 11 and the other 34 is attached to the tip 18 of the tether 15.
The fuel cap 45 can be locked by the fuel cap locking tool itself. This eliminates the need for the lid panel 40 to have a locking portion for locking the fuel cap 45. Moreover, one of the attachment / detachment members 35 has an L-shape, and the other 34 has a U-shape.
The attachment and detachment of b to the other 34 is easy and reliable.

Secondly, since the core 28 is connected to the distal end portion 18 of the tether 15 by the connecting portion 32, even if the tether 15 is subjected to a tensile force and the core 28 may come off from the clip body 20, There is no fear of losing the core 28. Also, since the core 28 can be held by the clip body 20 in a state of being inserted halfway into the clip body 20 (see FIG. 6), the core 28 is not used when the fuel cap locking device is used, that is, during transportation or management. Does not hang down and interfere with surrounding members.

Third, since the cap holding portion 11, the tether 15, the vehicle body attaching member 33, and the attaching / detaching member 35 are integrally formed of a soft resin, the fuel cap locking device has the following features. There is little possibility that the connecting portion between the tether 15 and the center portion 28 and the connecting portion between the tip portion 18 of the tether 15 and the like are separated. In addition, since the tether 15, the vehicle body attachment member 33, and the attachment / detachment member 35 are located in the plane where the cap holding portion 11 is located, it is easy to manufacture and mold a mold for injection molding.

Finally, in a vehicle in which the lid panel 40 is on the left side of the vehicle body (most vehicles in Japan are of this type), the fuel cap 45 can be easily and reliably locked. <Second Embodiment> Although the fuel cap locking device of the first embodiment can be suitably used for a vehicle having a lid panel on the left side, vehicles having a lid panel on the right side also run in Japan and Europe. are doing. In this type of automobile, the lid panel is opened to the right when refueling, so that the cap holding portion for holding the fuel cap is located on the left, and the vehicle body attaching portion attached to the lid panel is located on the right.
Accordingly, the tether of the fuel cap locking tool is reshaped in a C-shape during refueling.

In consideration of the above, as shown in FIG.
The tether 52 is extended from the cap holding portion 51 as shown by a solid line or as shown by a two-dot chain line, that is, an extension of the tether 52 forms a chord 53a or 53b of the cap holding portion 51. One surface 54a of FIG.
At the top) and a clip body 55 similar to the clip body 20 at the tip and a core 57 similar to the core 28 at the tip.
On the other surface 54b (the lower surface in FIG. 13), a locked portion 58 similar to the locked portion 34 is formed. Also,
A locking portion 59 similar to the locking portion 13 is formed below the cap holding portion 51, that is, on the same side as the locked portion 58 with respect to the tether 52.

The fuel cap locking device 50 is a tether 5
2 is attached to the lid panel 40 by the vehicle body attaching portions 55 and 57, the fuel cap (not shown) is held by the cap holding portion 51, and the tether 52 is bent into a C-shape, and the detachable member 58 and The fuel cap is locked on the fuel cap locking tool 50 by 59. <Modification> FIGS. 14 (a) and 14 (b) show a fuel cap locking device in which the configuration of the vehicle body mounting portion is modified. FIG. 14A is an enlarged front view showing a vehicle body mounting portion, and FIG. 14B is a cross-sectional view taken along line 14-14 of FIG.

A diametrical slit 67 is formed in the cylindrical portion 66 rising from the base 64 of the clip body 65 from the upper open end. A large-diameter portion 68a, a conical portion 68b, and a small-diameter portion 68c are formed on the inner peripheral surface of the cylindrical portion 66, and one annular groove 68d is formed on the outer peripheral surface. In addition, the connecting portion 73 allows the distal end portion of the tether, that is, the base portion 6.
Three annular projections 71a, 71b, and 71c are formed on the outer peripheral surface of the round bar 71 rising from the base 72 of the core 70 connected to the core 4. Thereby, when the round bar portion 71 of the core 70 is inserted into the tubular portion 66 of the clip body 65,
The annular projection 71a at the tip engages the conical surface 68b, the tip of the tubular portion 66 is enlarged in diameter, and the through-hole 4 of the lid panel 40 is formed.
