Description

  The present invention relates to an eggplant.

When connecting a pet with a lead (drawing string), a nascar may be used to connect a collar or a trunk worn on the pet and the tip of the lead. This eggplant is provided with a hook part for engaging with and disengaging from a collar and a body ring on one end side of the main body part, and a connecting part for connecting with a lead on the other end part of the main body part. It is supposed to be.
In this type of eggplant, the hook portion is provided with a rod member that opens and closes an engagement / disengagement port provided in the hook portion by axial movement along the main body portion. This rod member is urged so as to always close the engagement / disengagement port by a closing spring incorporated in the main body.

The rod member is provided with an operation projection that protrudes to the side of the main body, and the main body portion is provided with a movement groove for allowing the operation projection to move together with the rod member. .
By the way, in this kind of eggplant, when the pet unexpectedly behaves and the lead is caught by the operation protrusion, the operation protrusion is pushed back the movement groove, and the rod member moves, as a result. There was a problem that the hook was opened and the lead was released.

  Therefore, in order to solve this, a lateral groove that branches at a right angle from the moving groove to the circumferential direction is formed with respect to the main body portion, and when the rod member closes the hook opening of the hook portion, A lock mechanism has been proposed in which the protrusion is rotated from the moving groove to the lateral groove (see, for example, Patent Document 1).

Utility Model Registration No. 3139072

  In the lock mechanism of the rod member adopted in the conventional eggplant, the operation protrusion is simply rotated by about 90 ° in order to fit into the lateral groove. For this reason, it is relatively easy for the operation protrusion fitted in the lateral groove to reversely rotate in the direction of returning to the moving groove. That is, the problem that the hook opening / closing of the hook part opens unexpectedly and the lead is detached cannot be surely prevented.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an eggplant that can never open an engagement / disengagement port provided in a hook portion unless operated with motivation.

In order to achieve the above object, the present invention has taken the following measures.
That is, according to the present invention, a hook part for engagement / disengagement is provided on one end side of the main body part, and a connection part with another member is provided on the other end part. A rod member that opens and closes by axial movement along the axis and a closing spring that normally biases the rod member in a closing direction is provided. The rod member is connected to a connecting portion with a pivot perpendicular to the moving axis as a fulcrum. An operation knob is provided to be swingable so that the tail end directed toward and away from the main body part, and a movement groove is formed in the main body part to allow movement of the operation knob toward the connecting part. A lock piece that engages with the tail end of the operation knob to prevent the rod member from opening and moving toward the side of the main body at the end of the moving groove near the connecting portion is closed when the engagement / disengagement port is closed by the rod member. It is characterized by projecting.

A lock spring is provided between the rod member and the operation knob so as to apply a biasing force around the pivot axis to the operation knob so that the tail end of the operation knob is in contact with the main body. Is preferred.
It is preferable that the rod member is provided with a knob support portion that protrudes laterally through the movement groove of the main body portion, and the pivot is provided at the protruding end portion of the knob support portion. is there.

  The eggplant according to the present invention can prevent the engagement / disengagement opening provided in the hook portion from being opened unless operated with motivation.

It is the side view which showed the time of non-use of the eggplant concerning this invention. It is the side view which showed the state which operated the operation knob in the eggplant concerning this invention. It is the side view which showed the state which moved the rod member with the operation knob in the eggplant concerning this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1-5 has shown one Embodiment of the NASKA 1 which concerns on this invention. The eggplant 1 is provided with a hook portion 3 on one end side of the main body portion 2 for engaging with and disengaging from a pet collar or a trunk ring. A ring-shaped connecting portion 4 is provided for connecting to the above.

  In the eggplant 1 according to the present invention, an operation lock mechanism 6 is provided so that the engagement / disengagement port 5 provided in the hook portion 3 cannot be opened / closed unless operated with motivation. In addition, in the eggplant 1 of the present embodiment, the connecting portion 4 is formed in a ring shape, and the connecting portion 4 is attached to the main body portion 2 so as to be turnable around the turning shaft 7. . However, the point that the connecting portion 4 is ring-shaped or provided on the main body portion 2 via the pivot shaft 7 is an example, and is not limited at all. Further, the use (target to be engaged) of the hook portion 3 and the connecting portion 4 is not limited at all.

Hereinafter, the hook portion 3 will be described in detail.
The hook portion 3 is formed in a C-shaped ring shape that is partially open in the circumferential direction, and is formed by a hook engagement port 8 formed in the ring and a portion in which a circumferential direction portion of the ring is opened. It has an engagement / disengagement port 5.
The hook portion 3 has a rod member 11 held so as to be axially movable in a shaft hole 10 formed toward the main body portion 2, and pushes the rod member 11 out of the shaft hole 10 at the bottom of the shaft hole 10. And a closing spring 12 housed in the housing. Therefore, the rod member 11 is configured to always close the engagement / disengagement port 5 by receiving the pushing biasing force by the closing spring 12 in the shaft hole 10.

  The rod member 11 is integrally provided with a knob support portion 15 projecting to the side of the main body 2, and a pivot axis orthogonal to the movement axis of the rod member 11 is provided at the protruding end portion of the knob support portion 15. An operation knob 17 is held via 16. The operation knob 17 has a hollow structure with a U-shaped cross section as shown in FIG. 2, and covers the knob support 15 from above with the hollow portion facing downward. .

Therefore, the operation knob 17 remains swinging around the pivot 16 as a fulcrum, while protruding to the side of the main body 2.
The operation knob 17 is connected to the knob head 17a, which extends from the swing fulcrum part toward the hook part 3 from the position where the pivot 16 is provided (swing fulcrum part), and the swing fulcrum part. And a knob tail portion 17 b extending long toward the portion 4. When the operation knob 17 is viewed from the side, the vicinity of the oscillating fulcrum portion is the bulky, and the back side has a gentle convex arc surface so as to be lower as the knob tail portion 17b.

  A knob head 17 a of the operation knob 17 is formed so as to stand up from a first operation surface 18 formed by a convex arc surface in the vicinity (the most bulky portion) of the swing fulcrum portion and the engagement / disengagement port 5 of the hook portion 3. The second operation surface 19 is provided. The first operation surface 18 and the second operation surface 19 are adjacent to each other, and when a finger is pressed against the first operation surface 18 as shown in FIG. 4, an operation force by the finger is also applied to the second operation surface 19. The positions are close enough to be able to.

The first operation surface 18 and the second operation surface 19 are preferably provided with a non-slip projection 20.
As shown in FIG. 2, the knob support 15 provided on the rod member 11 is a portion protruding from the main body 2 to the side (a portion covered by the operation knob 17), and its protruding side (upper side in FIG. 2). It is formed in a bifurcated shape so as to open. At the center of the bifurcated portion, a spring accommodating recess 21 is formed so as to pass through in the same direction as the movement direction of the rod member 11 (left and right direction in FIG. 1).

And the pivot 16 is constructed in the state which crosses the inside of the spring accommodation recessed part 21 in the forked branch part of this knob support part 15. As shown in FIG. Both ends of the pivot 16 protrude from both side surfaces of the knob support 15, and the operation knob 17 is held by the protruding shaft ends on both sides.
Further, a lock spring 22 is inserted through the pivot 16 at a portion that crosses the inside of the spring accommodating recess 21. The lock spring 22 is a winding spring having spring legs 22a and 22b protruding in two directions. As shown in FIG. 1, the lock spring 22 is in a state where both spring legs 22a and 22b are brought close to each other and tightened (a state in which a spring force for spreading in the rewinding direction is accumulated), as shown in FIG. The leg 22 a is engaged with the bifurcated branch portion of the knob support 15, and the other spring leg 22 b is engaged with the knob head 17 a side of the operation knob 17.

Therefore, between the rod member 11 and the operation knob 17, the tip of the knob tail portion 17 b of the operation knob 17 (hereinafter, this tip is referred to as “tail end 23”) is brought into contact with the side surface of the main body 2. A spring biasing force is generated.
On the other hand, the main body portion 2 allows the knob support portion 15 of the rod member 11 to protrude sideways and allows the movement of the knob support portion 15 when the operation knob 17 is moved toward the connecting portion 4. A moving groove 25 is formed.

The moving groove 25 protrudes from the side surface of the main body 2 with respect to a position (when the rod member 11 closes the engagement / disengagement port 5) closer to the connecting portion 4 side than the tail end 23 of the operation knob 17. The lock piece 27 is provided in the state.
The lock piece 27 protrudes to engage with the tail end 23 when the operation knob 17 is to be pushed toward the connecting portion 4 while the tail end 23 is in contact with the side surface of the main body 2. It is supposed to have a height. However, when the operation knob 17 is swung around the pivot 16 and the tail end 23 is moved away from the side surface of the main body 2, the protrusion height is regulated so as to disengage from the tail end 23.

  That is, when the operation knob 17 is pushed toward the connecting portion 4 while the engagement between the tail end 23 of the operation knob 17 and the lock piece 27 is disengaged, the operation knob 17 and the knob support portion 15 are connected. It can be moved toward the part 4. Therefore, since the rod member 11 also moves along the main body 2 by such movement of the operation knob 17, the engagement / disengagement port 5 of the hook portion 3 is opened by the movement of the rod member 11.

As described above, the operation knob 17 provided to be swingable with respect to the rod member 11 and the lock piece 27 that can be engaged and disengaged according to the swinging state of the operation knob 17. An operation lock mechanism 6 is configured.
Next, the usage situation of the NASCAN 1 which concerns on this invention is demonstrated.
Since the lock knob 22 is loaded between the operation knob 17 and the main body 2, the tail end 23 of the operation knob 17 is not connected to the main body 2 when the operation knob 17 is not operated as shown in FIG. 3. It is in contact with the side.

Moreover, since the rod member 11 always receives the pushing biasing force of the closing spring 12 loaded in the shaft hole 10 and closes the engagement / disengagement port 5 of the hook portion 3, the tail end 23 of the operation knob 17 is locked. The state of engaging with the piece 27 is maintained.
When the hook portion 3 is engaged with a collar or a trunk ring, first, as shown in FIG. 4, a finger is applied to the first operation surface 18 of the operation knob 17 and the finger is pushed toward the engagement / disengagement port 5. To do. Thereby, the operation knob 17 can be swung around the pivot 16 while resisting the spring force of the lock spring 22 (see arrow X). By such swinging of the operation knob 17, the tail end 23 is separated (raised) from the main body 2, and the engagement between the tail end 23 and the lock piece 27 is released.

When the first operation surface 18 of the operation knob 17 is pushed with a finger and the operation knob 17 is swung, the finger inevitably reaches (turns around) the second operation surface 19 side. Therefore, the finger is pulled as it is to the connecting portion 4 side, and the second operation surface 19 is pushed toward the connecting portion 4 as shown in FIG.
At this time, since the tail end 23 of the operation knob 17 is separated from the main body 2, it is possible to get over the lock piece 27, and the operation knob 17 can be moved toward the connecting portion 4 (arrows). See Y). By such movement of the operation knob 17, the rod member 11 can be moved together, and the engagement / disengagement port 5 of the hook portion 3 can be opened.

  After the operation knob 17 is swung, the second operation surface 19 and the pivot 16 of the operation knob 17 are in the same direction as the direction in which the rod member 11 is moved toward the connecting portion 4 (parallel to the movement axis). On the line). This is because the knob support 15 is provided for the rod member 11 and the pivot 16 is disposed outside the main body 2. Such an arrangement of the second operation surface 19 and the pivot 16 has an effect of efficiently transmitting an operation force applied to the second operation surface 19 to the rod member 11, and as a result, a movement operation (hook) of the operation knob 17. Opening of the engagement / disengagement port 5 in the portion 3 is an advantage.

When the engagement / disengagement port 5 thus opened is engaged with the collar or the trunk ring and the operation force applied to the operation knob 17 is released, the rod member 11 and the operation knob 17 return to the original state, and the hook portion 3 The engagement / disengagement port 5 is closed, and the hook engagement port 8 is held in a closed loop state.
After the hook portion 3 is connected to the collar or the trunk ring in this way, the rod member 11 never moves unless the operation knob 17 is swung with motivation. The problem that the rod member 11 moves in the direction of opening the engagement / disengagement port 5 can be thoroughly prevented.

By the way, this invention is not limited to the said embodiment, According to the condition of implementation, it can change suitably.
For example, the connection part 4 can be replaced with a bolt connection structure or the like if it can be connected to other members. Moreover, it is also possible to make the connection part 4 the same structure as the hook part 3 (structure provided with the double-headed hook part 3 as the nascar 1).

The pivot 16 can also be provided at the axial center position of the lock member 11. In this case, the knob support 15 may be provided integrally with the operation knob 17.
The operation knob 17 can adopt an appropriate outer shape such as a rectangle.
