Abstract

The invention provides a sprue cover which can prevent a vehicle from being started without installing the sprue cover. The spout cover (100) is provided with a restricting member (19) that restricts the movement of the locking member to the locking position in a state where the spout cover is not attached to the injection pipe (P), and the restricting member (19) prevents the rotation of the core (2) to the locking position where the key (K) can be removed. Thus, the key (K) can be removed only by attaching the nozzle cover (100) to the injection pipe (P) and rotating the core body (2) to the locking position.

Detailed Description

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

(first embodiment)

Fig. 1 is an exploded perspective view of the filler cap according to the present embodiment.

Fig. 2 is a front view of the spout cover 100.

Fig. 3 is a rear view of the spout cover 100.

In the following description, specific numerical values, shapes, materials, and the like are described, but these may be appropriately changed.

In the following description, the right side in fig. 1, the left side in fig. 4, the anterior side in fig. 2, and the depth side in fig. 3 are referred to as "front", the left side in fig. 1, the right side in fig. 4, the depth side in fig. 2, and the anterior side in fig. 3 are referred to as "rear", and a direction corresponding to the radial direction of the cylindrical portion of the core 2 is referred to as "radial direction".

As shown in fig. 1, the spout cover 100 of the present embodiment includes a main body 1, a core 2, a lock pin 3, a lock member 13, and a restricting member 19 as main components.

The main body 1 is detachably and hermetically attached to an injection pipe P (see fig. 8, 10, and 12) as a liquid injection port formed in a box body with a sealing member 12 interposed therebetween.

A core housing portion 1a is formed at the center of the main body 1 so as to penetrate in the front-rear direction.

The core 2 is attached to a core housing portion 1a formed in the main body 1, and is rotationally moved between a lock position and an unlock position by an operation of a key K (see fig. 6). The core 2 is inserted into the core housing portion 1a with the baffle 2a attached. The baffle 2a projects into a recess, not shown, formed in the core housing 1a, thereby holding the core 2 so as not to be pulled out from the core housing 1 a. A protrusion 2c protruding rearward is provided at the rear end of the core 2. The projection 2c is disposed at a position eccentric from the rotation center of the core 2, and engages with a cam hole 13a of a lock member 13 described later.

Further, the core 2 accommodates a plurality of pins 3.

Fig. 6 is a sectional view showing the lock pin 3 in the core 2 in a state where the key K is inserted. Fig. 6 shows a state in which the key K is inserted with the core 2 in the lock position.

As shown in fig. 6, the lock pin 3 is housed in the lock pin housing portion 2b of the core 2. The lock pin 3 is biased in a direction protruding from the core 2 by a lock pin spring 3 a.

In the core housing portion 1a of the main body 1, a groove 1b capable of receiving the lock pin 3 protruding from the core 2 is formed only in the lock position. The groove is not formed except for the locking position (e.g., the unlocking position).

Therefore, the striker 3 can protrude outward of the core 2 only in a state where the core 2 is located at the lock position.

When the key K with the correct key bits is inserted into the deepest part, all the pins 3 are accommodated in the core body 2 as shown in fig. 6. However, each pin 3 protrudes outward of the core through the key K in the middle of the insertion or removal of the key K. In the case where the protrusion is not allowed, the key K cannot be inserted or extracted.

If the key K is to be removed from the unlock position where the groove 1b is not formed, the lock pin 3 abuts against the inner wall of the core housing portion 1a of the main body 1 and cannot protrude from the core 2, and therefore the removal of the key K is prevented by the lock pin 3. Thus, the key K can be inserted and removed only in the lock position. The structure of the core 2 and the lock pin 3 is a commonly used structure.

As shown in fig. 1, a shutter 4, a shutter spring 5, a shutter holder 6, a core cover 7, a protective member spring 8, a protective member seal 9, and a keyhole protection member 10 are provided in front of the core 2.

The shutter 4 is biased by a shutter spring 5 to close the keyhole of the core 2. When the key K is inserted, the shutter 4 is pushed open by the key K and rotationally moves and retreats.

The shutter fixing member 6 is located between the shutter 4 and the core cover 7, and holds the shutter 4.

The core cover 7 is fixed to the core 2 so as to cover the tip end side of the core 2 and hold the shutter fixing member 6 and the shutter 4 on the core 2.

The protective member seal 9 is attached to the back surface side of the keyhole protection member 10 by a seal holder 22, and is in close contact with the front surface of the core cover 7 in a state where the keyhole protection member 10 is closed, thereby preventing foreign matter from entering the keyhole 2 d.

The keyhole protection member 10 is attached to the main body 1 so as to be rotatable about a shaft 11, and can be opened and closed by a user's operation. The keyhole protection member 10 is biased in the closing direction by the protection member spring 8, and covers the keyhole 2d to prevent foreign matter from entering the keyhole 2d unless a user operates the protection member.

The seal member 12 is sandwiched between the main body 1 and the cover 14 and fixed to the main body 1. When the nozzle cover 100 is attached to the injection pipe P, the sealing member 12 is closely attached to the end of the injection pipe, preventing fuel leakage and preventing foreign matter from entering the case. In the present embodiment, the seal member 12 is formed of two members, but is not limited thereto.

The lock member 13 is formed by press working a metal plate material, and includes a cam hole 13a, a tube locking portion 13b, and a locking portion 13 c.

The cam hole 13a is formed in a portion along the rear end surface of the core 2, and engages with the projection 2c of the core 2.

As shown in fig. 5, the tube locking portion 13b is formed to protrude radially outward of the substantially cylindrical shape of the cover 14 and can protrude from the cover 14.

The lock member 13 receives a driving force from the projection 2c via the cam hole 13a by rotation of the core 2, and moves in the left-right direction in fig. 5. In fig. 5, the lock member 13 is moved to a lock position where the tube locking portion 13b of the lock member 13 protrudes rightward in the drawing from the cover 14, and the tube locking portion 13b is engaged with an engagement portion (not shown) formed in the injection tube P.

In the lock position of fig. 5, the tube locking portion 13b of the lock member 13 engages with the injection tube P, and prevents the main body 1 from being removed from the injection tube P.

Further, when the core 2 is moved to the unlock position, the lock member 13 is moved to the unlock position: the tube locking portion 13b is disengaged from the injection tube P, and the main body 1 can be detached from the injection tube P.

Further, the locking member 13 is formed with an engaging portion 13c that engages with a regulating portion 19a of a regulating member 19 described later. The locking portion 13c of the present embodiment is formed at a portion that is bent upward from the surface where the cam hole 13a is formed.

The regulating member 19 is pivotally supported by a shaft 20 inserted into the shaft insertion hole 1c of the main body 1 in a swingable state, and a detachable detection portion 19b is formed at one end, which is the front side, of the regulating member 19, and a regulating portion 19a is formed at the other end, which is the rear side.

Further, a return spring (urging member) 21 that urges the regulating member 19 in the following direction is provided between the regulating member 19 and the main body 1: the attachment/detachment detecting portion 19b is projected outward in the radial direction of the filler pipe P, and the restricting portion 19a is retracted inward in the radial direction of the filler pipe P, that is, the restricting portion 19a engages with the locking portion 13c of the lock member 13.

The radial outer end of the attachment/detachment detection portion 19b is a slope that abuts the edge of the injection pipe P when the main body 1 is attached to the injection pipe P, and the attachment/detachment detection portion 19b can be retracted radially inward against the urging force of the return spring 21.

The restricting portion 19a moves forward and backward in conjunction with the attachment/detachment detecting portion 19b, and when the main body 1 is detached from the injection pipe P, the restricting portion 19a moves to a position where the locking member 13 is locked and movement of the locking member 13 is restricted. When the main body 1 is attached to the inlet pipe P, the restricting portion 19a moves to a position where the locking of the lock member 13 is released.

With this configuration, when the main body 1 is detached from the injection pipe P, the attachment/detachment detecting portion 19b is moved radially outward by the biasing force of the return spring 21, and the restricting portion 19a is moved to a position where the lock member 13 is locked and the movement of the lock member 13 is restricted. When the main body 1 is assembled to the filler pipe P, the attachment/detachment detecting portion 19b is pushed and moved radially inward, and the restricting portion 19a is moved to a position where the locking of the lock member 13 is released.

Next, the operation of the lock member 13 and the regulating member 19 will be described in more detail.

The state shown in fig. 7 and 8 in which the core 2 is in the locked position in the state attached to the filler pipe P corresponds to the state in which the vehicle is in use. In this state, the key K is either removed or can be removed even if the key K is inserted. In this state, the tube locking portion 13b projects radially outward, and the attachment/detachment detecting portion 19b is pushed radially inward by the injection tube P, so that the locking of the locking member 13 is released. This allows the core 2 to be rotated using the key K without restricting the movement of the lock member 13.

From the state of fig. 7 and 8, the key K is inserted to rotate the core body 2 to the unlock position for refueling, and the state of fig. 9 and 10 is obtained. When the core 2 is rotated to the unlock position, the core 2 is rotated in the direction of the arrow a in fig. 9, whereby the lock member 13 is moved in the direction of the arrow B to become the unlock position, and the lock member 13 also becomes the unlock position (the state of fig. 9 and 10) where the tube locking portion 13B is moved radially inward. When the state is shown in fig. 9 and 10, the spout cover 100 can be removed from the spout P by pulling it out.

Since the force for pressing the attachment/detachment detection portion 19b is lost with respect to the filler cap 100 detached from the filler pipe P, the attachment/detachment detection portion 19b protrudes in the arrow C direction (radially outward). In conjunction with the movement of the attachment/detachment detecting portion 19b, the restricting portion 19a moves in the direction of arrow D (radially inward), and the locking portion 13c engages with the restricting portion 19a, thereby bringing the state shown in fig. 11 and 12.

In the state of fig. 11 and 12, since the core 2 is located at the unlock position, the key K is kept inserted into the core 2, and the regulating member 19 is located at the position where it engages with the lock member 13. Therefore, when the core 2 is turned in the arrow E direction together with the key K to be the lock position, the lock member 13 is moved in the arrow F direction. However, in the G portion in the figure, since the movement of the lock member 13 is restricted by the restricting member 19, the core body 2 connected to the lock member 13 cannot be rotated by the key K.

Therefore, the core body 2 cannot be rotated to a lock position where the key K can be inserted and removed, and there is no fear that the key K is removed in a state where the sprue cover 100 is removed. When the key K is to be removed, the filler cap 100 needs to be attached to the filler pipe P, the regulating member 19 needs to be swung, and the engagement between the regulating member 19 and the lock member 13 needs to be released.

As described above, in the spout cover 100 of the first embodiment, the core 2 is housed in the main body 1, and the fixing and the releasing of the fixing of the spout cover 100 to the injection pipe P are performed by the rotational operation of the key K inserted into the core 2. Therefore, the spout cover 100 does not need to be attached or detached by rotating the main body 1, and thus, the convenience is improved and no excessive load is applied to the structural members.

The spout cover 100 is provided with a restricting member 19 that restricts the movement of the lock member to the lock position in a state where the spout cover is not attached to the filler pipe P, and the rotation of the core body 2 to the lock position where the key K can be removed is prevented by the restricting member 19. Thus, the key K can be removed only by attaching the spout cover 100 to the filler pipe P and rotating the core body 2 to the lock position.

Therefore, it is possible to prevent the vehicle from being started after forgetting to attach the nozzle cover 100 to the filler pipe P after refueling, and to prevent oil leakage from the tank and intrusion of foreign matter into the tank.

In the spout cover 100 of the first embodiment, a detachable detection portion 19b for detecting the detachment of the spout cover 100 to the injection pipe P and a regulating portion 19a for regulating the movement of the lock member 13 are integrated with the regulating member 19. Therefore, the number of parts of the filler cap 100 can be reduced, the assembly can be facilitated, and the manufacturing cost can be controlled.

Further, in the spout cover 100 according to the first embodiment, the restricting member 19 is formed as a swinging member, and the attachment/detachment detecting portion 19b at one end and the restricting portion 19a at the other end can be swung inward and outward in the radial direction of the spout pipe P with the substantially central portion thereof as a rotation axis, so that the structure can be simplified.

In the spout cover 100 according to the first embodiment, the restricting member 19 is formed as a swinging member, and when the restricting member 19 is operated by pressing or releasing the pressing by the spout P, the linear motion that is the attachment and detachment of the main body 1 can be converted into the swinging motion, i.e., the rotational motion, of the restricting member 19. Accordingly, in the spout cover 100 of the first embodiment, the burden imposed on the structural members is small, and the regulating member 19 can be efficiently operated.

(second embodiment)

In the second embodiment, the restriction member 219 is a member that moves linearly, and the locking portion 213c of the lock member 213 is provided further forward than in the first embodiment. The spout cover 200 of the second embodiment is the same as that of the first embodiment except that the locking member 213, the regulating member 219, and the return spring 221 are different from those of the first embodiment. Therefore, the same reference numerals are given to those parts which achieve the same functions as those of the first embodiment, and overlapping descriptions will be omitted as appropriate.

The lock member 213 is formed by press working a metal plate material, and includes a cam hole 213a, a tube locking portion 213b, and a locking portion 213 c.

The cam hole 213a is formed in a portion along the rear end surface of the core 2, and engages with the protrusion 2c of the core 2.

The tube locking portion 213b is formed to protrude radially outward of the substantially cylindrical shape of the cover 14, and can protrude from the cover 14.

The lock member 213 receives a driving force from the projection 2c via the cam hole 213a by rotation of the core body 2, and moves between a lock position and an unlock position. In fig. 14, the lock member 213 is moved to a lock position where the tube locking portion 213b of the lock member 213 protrudes from the cover 14, and the tube locking portion 213b is engaged with an engagement portion (not shown) formed in the injection tube P. The tube locking portion 213b of the lock member 213 is engaged with the injection tube P to prevent the main body 1 from being removed from the injection tube P.

Further, when the core 2 is moved to the unlock position, the lock member 213 is moved to the unlock position: the tube locking portion 213b is disengaged from the injection tube P, and the main body 1 can be detached from the injection tube P.

Further, the lock member 213 is formed with a locking portion 213c that engages with a restricting portion 219a of a restricting member 219, which will be described later. Unlike the locking portion 13c of the first embodiment, the locking portion 213c of the second embodiment is formed at a position farther forward than the surface on which the cam hole 213a is formed and at a position near the seal member 12.

The regulating member 219 is provided in the vicinity of the seal member 12 in a linearly movable state with respect to the body 1, and a regulating portion 219a is formed on the radially inner side and a detachable detecting portion 219b is formed on the radially outer side.

Further, a return spring (urging member) 221 that urges the restriction member 219 in the following direction is provided between the restriction member 219 and the main body 1: the attachment/detachment detecting portion 219b and the restricting portion 219a are projected outward in the radial direction of the injection pipe P.

The radially outer tip of the attachment/detachment detecting portion 219b is a slope, and when the body 1 is attached to the filler pipe P, the edge of the filler pipe P abuts against the slope, and the restricting member 219 can be retracted radially inward against the biasing force of the return spring 221.

The restricting portion 219a moves forward and backward in conjunction with the attachment/detachment detecting portion 219b, and when the main body 1 is detached from the injection pipe P, the restricting portion 219a moves to a position where the lock member 213 is locked to restrict the movement of the lock member 213. When the main body 1 is fitted to the inlet pipe P, the restricting portion 219a moves to a position where the locking of the lock member 213 is released.

With the above configuration, the spout cover 200 of the second embodiment can perform the same operation as the spout cover 100 of the first embodiment. The operation of the restricting member 219 is the same as that of the first embodiment except for whether it is swinging or linear travel, and therefore, the following description will be made for simplicity.

In the state shown in fig. 14, the tube locking portion 213b protrudes radially outward, and the attachment/detachment detecting portion 219b is pushed inward (in the direction of arrow H) in the radial direction by the injection tube P, so that the locking of the lock member 213 is released. Therefore, the core 2 can be rotated using the key K without restricting the movement of the lock member 213.

When the core body 2 is rotated to the unlock position from the state of fig. 14, the lock member 213 also becomes the unlock position (the state of fig. 15) at which the tube locking portion 213b moves radially inward (the direction of arrow I). When the state of fig. 15 is reached, the spout cover 200 can be removed from the injection pipe P by pulling out.

Fig. 16 is a perspective view showing the spout cover 200 in a state detached from the filler pipe P with the core 2 in the unlocked position.

Since the force for pressing the attachment/detachment detection portion 219b is lost with respect to the filler cap 200 detached from the filler pipe P, the attachment/detachment detection portion 219b protrudes in the arrow J direction (radially outward). In conjunction with the movement of the attachment/detachment detecting portion 219b, the restricting portion 219a also moves in the direction of arrow J (radially outward), and at the portion M in the figure, the locking portion 213c engages with the restricting portion 219a, and the lock member 213 cannot move in the direction of arrow L, so that the core 2 cannot be rotated by the key K.

Therefore, the core 2 cannot be rotated to a lock position where the key K can be inserted and removed, and there is no fear that the key K is removed in a state where the bet cover 200 is detached.

As described above, in the spout cover 200 of the second embodiment, the restriction member 219 is linearly moved, so that the attachment/detachment detection portion 219b and the restriction portion 219a are linearly moved inward and outward in the radial direction of the spout P, respectively, thereby simplifying the structure.

In the spout cover 200 of the second embodiment, the restricting member 219 is a member that moves linearly, and thus when the restricting member 219 is actuated by pressing or releasing the pressing of the spout P, the linear motion that is the attachment and detachment of the main body 1 is converted into the linear motion in the orthogonal direction. Therefore, the spout cover 200 of the second embodiment imposes a greater burden on each member than the case of the regulating member 19 constituted by a swinging member as in the first embodiment, but the regulating member 219 can be further downsized, and the space of the main body 1 for accommodating the regulating member 219 can be further reduced.

1. A spout cap, comprising:

a main body detachably attached to a liquid inlet formed in a case;

a core mounted in a core housing formed in the body and rotatably moved between a lock position and an unlock position by a key operation;

a lock pin that is housed in the core body and is capable of protruding outward of the core body only in a state where the core body is located at a lock position;

a locking member that is linked with rotation of the core body, moves to a locking position where the locking member engages with the liquid injection port and prevents the main body from being removed from the liquid injection port when the core body moves to the locking position, and moves to an unlocking position where the locking member releases the engagement with the liquid injection port and enables the main body to be removed from the liquid injection port when the core body moves to the unlocking position;

a restricting member that restricts the movement of the locking member to a locking position in a state where the main body is detached from the liquid inlet,

the restricting member includes:

a loading/unloading detection part which moves according to the loading/unloading of the main body to the liquid injection port;

a restricting portion that moves forward and backward in conjunction with the attachment/detachment detecting portion, moves to a position where the restricting portion is locked to the lock member to restrict movement of the lock member when the main body is detached from the liquid injection port, and moves to a position where the locking of the lock member is released when the main body is attached to the liquid injection port,

the said pouring-spout lid is characterized in that,

the restricting member is pivotally supported to be capable of swinging with respect to the main body,

the attachment/detachment detection portion is formed at one end of the regulating member, and the regulating portion is formed at the other end,

a biasing member that biases the regulating member in the following directions is provided between the regulating member and the main body: and a direction in which the attachment/detachment detection portion protrudes outward in a radial direction of the liquid injection port and the restriction portion is retracted inward in the radial direction of the liquid injection port.

2. A spout cap, comprising:

a main body detachably attached to a liquid inlet formed in a case;

the restricting member includes:

the said pouring-spout lid is characterized in that,

the regulating member is provided in a state of being capable of linear travel movement projecting radially outward of the liquid injection port with respect to the main body,

a biasing member that biases the regulating member in the following directions is provided between the regulating member and the main body: a direction in which the attachment/detachment detecting portion and the regulating portion are projected outward in a radial direction of the liquid inlet,

the loading/unloading detection part has a radial outer front end portion formed as an inclined surface, and the restricting member is attached to the liquid inlet through the body so as to be retracted radially inward against the urging force of the urging member.
