Description

  TECHNICAL FIELD The present invention relates to an animal connector mainly used for connecting a draw string or a mooring string to a collar, a trunk ring, a mooring tool, or the like of an animal such as a dog or a cat, and is mainly provided in a collar, a torso, or a mooring tool. It is used by detachably connecting to the ring.

  Such a connector belongs to what is commonly referred to as an eggplant ring regardless of the application. However, as shown in FIGS. 5 to 7, the animal connector particularly includes a base b1 connected to a base end ring a and the base b1. A main body b having a hook part b2 extending from the base part b1, a spring biased and projecting in the base part b1, and a closing habit of closing the opening part b4 of the hook part b2 by pressing against the tip b3 of the hook part b2; It has a basic configuration including a locking pin c from which a backward operation part c1 protrudes on the side of b1.

  Such an animal connector k is used by connecting the proximal end ring a to the leading end of a drawstring or both ends of a mooring string j shown in FIG. The animal connector k connected to the mooring string j or the like has the anchor portion c or the collar d attached to the animal shown in FIG. After being hooked on the connecting rings g and h provided on the anchoring device f, the locking pin c is released from the retreating operation so that the opening b4 is closed and connected.

  The base end ring a is normally rotatably connected to the base b1 of the main body b to give the connecting portion a degree of freedom. However, as shown in FIG. 5, there is no such freedom of rotation between the hook portion b2 and the connecting portion between the connecting rings g and h, and the connecting rings g and h, particularly the collar d, are provided. The connecting ring g does not have a degree of freedom to rotate with respect to the collar d. Due to these inconveniences in connection and sudden changes in the movement of animals, the connection between the animal connection tool k and the connection ring g, etc., is drowned, and the animal connection tool in this state of dripping The catching force and the pushing force to the backward operation side of the backward operation part c1 of the locking pin d of k are inadvertently acted, and the opening part b4 of the hook part b2 is opened and connected to the hook part b2 as shown in FIG. It sometimes happens that the connection with the ring g or the like is broken. Here, FIG. 6 shows a state in which the connecting ring g is turned between the hook portion b2 and the buckle d1 of the collar d and loses freedom, and the retracting operation portion of the locking pin c of the hook portion b2 to which tension is applied. A state is shown in which c1 is pushed to the backward operation side and the opening d4 of the hook part d2 is opened.

In order to cope with such a situation, the present applicant has already proposed that an intermediate ring is connected between the connecting ring g and the hook part d2 to increase the degree of freedom of connection (see Patent Document 1). In addition, techniques for improving the structure of the animal connector itself are already known (see, for example, Patent Documents 2 and 3). The techniques disclosed in Patent Documents 2 and 2 are configured so that even if the connecting ring g is twisted, the hooks are prevented from being caught in the retracting operation direction c1 of the locking pin d of the animal connector k or exerting pushing force. The shape and installation position of the part d2 and the locking pin c are improved.

  However, the technique disclosed in Patent Document 1 has a problem that cannot be avoided, although the probability of disconnection decreases. In addition, the techniques disclosed in Patent Documents 2 and 3 are special products that are difficult to form and assemble, causing a cost increase.

  The present invention has been made in view of such problems, and is an animal connector that can reliably prevent disconnection by an inexpensive method that simply uses a simple accessory with the usual form and structure. It is a problem to provide.

  In order to solve the above-described problems, the animal connector of the present invention includes a base portion connected to a base end ring and a main body including a hook portion extending from the base portion, and a spring bias in the base portion. An animal connector having a closing behavior that presses against the tip of the protruding hook portion and closes the opening portion of the hook portion, and has a locking pin with a retracting operation portion protruding to the side of the base portion. The base has a semicircular arc cross section so that it can be elastically attached and detached from the side, and the attachment / detachment opening opens to the side, and when attached to the base, the retraction operation part and the hook on the base on the retraction operation side from this It is characterized in that it is provided with a stopper that stretches between the parts and prevents the locking pin from retreating via the retreat operation part.

  In such a configuration, the stopper provided in combination with the animal connector of the normal form and structure is simply elastically fitted to the base of the main body from the side using the lower half arc section having elasticity. Since the stopper is stretched between the proximal-side catch portion and the retraction operation portion of the locking pin around the base portion, the locking pin is retreated with the retraction operation portion by an inadvertent external force, or by the retraction operation portion. The action of preventing the reverse movement is obtained. In addition, the stopper can be easily removed from the base to the side using elasticity, and in the detached state, the tension is released, so that the locking pin can be operated backward to connect or release the connection. it can.

  In the above, the stopper is further provided with a notch-shaped portion that engages in the circumferential direction of the base by the retreat operation unit and stops around the base at the contact end with the retraction operation unit. It can be.

  In such a configuration, in addition to the above, a stopper is further attached to the base of the main body, and is stretched around the base between the proximal-side hooking portion and the retracting operation portion of the locking pin. In order to prevent retraction, the notch-shaped part is engaged with the retraction operation part of the locking pin in the base circumferential direction, so that the stopper is prevented from rotating around the base part and even if it receives external force, Does not shift in the direction.

In the above, the retracting operation portion of the locking pin may further include a notch portion that engages so as to be sandwiched between the abutting end of the stopper and the base portion.
In such a configuration, in addition to the above, a stopper is attached to the base of the main body, and the stopper is retracted around the base between the proximal-side hooking portion and the locking pin retracting operation portion. In order to prevent this, the stopper is prevented from floating from the mounting position on the base of the main body by the engagement of the locking pin with the retracting operation portion.

  In the above, the stopper may be further connected to a part of the animal connector by a rope.

  In such a configuration, in addition to the above, the stopper is connected to a part of the animal connector, so that it is prevented from being inadvertently a single part. It is not obstructed to attach and detach it to the base of the main body.

  In the above, the stopper may be further characterized in that it is connected to the rope at the protruding portion from one part of the open edge of the attachment / detachment port.

  In such a configuration, in addition to the above, the stopper is removed from the attachment / detachment area to the base of the main body and connected to the animal connector, so that the connection with the animal connector is connected to the base of the stopper main body. No special external force is applied by the attachment / detachment, and the connecting portion of the stopper with the rope is a protruding portion from one part of the opening edge of the attachment / detachment opening, so that the connecting portion with the rope goes to the base of the stopper main body. There is no hindrance to the attachment and detachment.

  According to the animal connector of the present invention, by simply attaching a stopper combined with the animal connector to the base of the main body, it is possible to prevent the locking pin from being retracted by an inadvertent external force to the retracting operation portion. It is possible to prevent the animal from coming off and maintain the animal's accompanying state and mooring state. If the stopper is removed from the main body, the connection can be released by operating the locking pin backward. Further, the stopper can be easily and elastically attached to the base of the main body from the side, so that it is easy to use, and can be realized at low cost only by combining a simple stopper with an animal connector having a normal form and structure.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings to provide an understanding of the present invention. The following description is a specific example of the present invention and does not limit the description of the scope of claims.

  1 to 3 show an example of an animal connector 1 according to an embodiment of the present invention. The animal connector 1 includes a main body 10 having a base 3 connected to a base end ring 2 and a hook portion 4 extending from the base 3, and a hook portion protruding and biased by a spring (not shown) in the base 3. 4 is provided with a locking pin 5 having a closing behavior that closes the opening portion 4b of the hook portion 4 in pressure contact with the distal end 4a of the pin 4, and a retracting operation portion 5a protruding on the side of the base portion 3. At the same time, it is made of an elastic member, and has a semicircular arc cross section so that it can be elastically attached to and detached from the side of the base 3, and the attachment / detachment opening 6a is opened to the side, and the base 3 is shown in FIGS. In the mounted state, there is also provided a combination of a stopper 6 for preventing the locking pin 5 from retreating via the retraction operation portion 5a by stretching between the retraction operation portion 5a and the catch portion 3a on the base 3 on the retraction operation side. .

  In this way, the animal connector 1 having a normal form and structure is shown in FIG. 1 at the base 3 of the main body 10 by using the lower semicircular arc section having the elasticity of the stopper 6 provided in combination therewith. As shown in FIGS. 2 and 3, the stopper 6 is stretched around the base portion 3 between the proximal end side catching portion 3 a and the retracting operation portion 5 a of the locking pin 5 from the side. Therefore, there is obtained an action for preventing the locking pin 5 from being retracted with the retracting operation portion 5a by the inadvertent external force or being retracted by the retracting operation portion 5a. Further, the stopper 6 can be easily removed from the base 3 sideward by using elasticity, and in the detached state, the tension is released, so that the locking pin 5 is retreated by the retreat operation part 5a and the hook part. 4 can be opened and the hook portion 4 can be connected to a connecting portion 22 such as a D-ring of the collar 21 or a mooring tool (not shown) as shown in FIG. 4, or the connected state can be released. .

  As a result, by simply attaching to the base 3 of the stopper 6 body 10 provided in combination with the animal connector 1, the locking pin 5 is prevented from being retracted by an inadvertent external force to the retracting operation portion 5 a and the connection is released. It is possible to prevent the animal from being brought in and to maintain the animal's accompanying state and mooring state. Further, if the stopper 6 is removed from the main body 10, the locking pin 5 can be retracted to release the connection. The stopper 6 can be easily and elastically attached to the base 3 of the main body 10 from the side as shown by an arrow in FIG. 1 so that it is easy to use and easy to connect to the animal connector 1 having a normal form and structure. It can be realized at low cost simply by providing a combination of stoppers 6.

  Here, corresponding to the fact that the base portion 3 connected to the hook portion 4 is cylindrical, the stopper 6 is formed in a lower semicircular cross section having an inner diameter substantially equal to the outer diameter thereof and is smaller than the diameter of the base portion 3. It is assumed to have a width attaching / detaching port 6a. Accordingly, the stopper 6 can be attached to the base portion 3 while elastically widening the attachment / detachment opening 6a at the side peripheral portion of the base portion 3 from the side thereof, and the attachment / detachment opening 6a exceeds the diameter portion of the base portion 3. From the point of time, the stopper 6 is elastically restored to the initial width of the attachment / detachment opening 6a and is fitted into the attached state so as to wrap around the base portion 3 and is stable in the attached state, so that it does not inadvertently fall off. On the other hand, the stopper 6 can be removed with a temporary widening to the side of the base 3 until the diameter of the elastic base 3 of the attachment / detachment opening 6a exceeds the removal side.

  The elasticity of the stopper 6 necessary for the attachment and detachment can be easily obtained by forming the stopper 6 with an elastic resin or metal plate. It can also be. In the present embodiment, the resin molded product is lightweight, safe, and inexpensive, and a soft acrylic resin or the like is also environmentally friendly. The smaller the opening width of the attachment / detachment opening 6a is, the smaller the diameter of the base portion 3 is, the more difficult it is to remove and attach the half surface, but an appropriate design can be made in consideration of the elastic restoring force of the stopper 6.

  Moreover, although the hook part 3a on the base part 3 is provided in any way, in the illustrated example, it is assumed that a flange part normally formed at the base end to which the base end ring 2 of the base part 3 is connected is used. Therefore, there is no need for special improvement.

  Further, as shown in FIGS. 1 to 3, the stopper 6 is engaged with the contact end 6 b with the retreat operation portion 5 a in the circumferential direction of the base 3 by the retreat operation portion 5 a to prevent the rotation around the base 3. A notch-shaped portion 6c is provided. As a result, the stopper 6 is mounted on the base 3 of the main body 10 and is stretched around the base 3 between the proximal-side hooking portion 3 a and the retraction operation portion 5 a of the locking pin 5, and the locking pin 5 is retracted. In order to prevent this, the notch-shaped portion 6c is engaged with the structure operating portion 5a of the locking pin 5 in the circumferential direction of the base 3 so that the stopper 6 is prevented from rotating around the base 3 and receives external force. Even if there is, there will be no displacement in the circumferential direction, the stopper function will be poor, or it will not fall off.

  Further, the retracting operation portion 5a of the locking pin 5 has a notch portion 5b engaged so as to be sandwiched between the contact end 6b of the stopper 6 and the base portion 3 as shown in FIGS. It is said. As a result, the stopper 6 is attached to the base 3 of the main body 10 and is stretched around the base 3 between the proximal side catching portion 3a and the retracting operation portion 5a of the locking pin 5 to prevent the locking pin 5 from moving backward. However, the stopper 6 is prevented from being lifted from the mounting position of the main body 10 on the base portion 3 due to the engagement of the locking pin 5 with the retreat operation portion 5a. As a result, even if an external force in the removal direction is applied to the stopper 6, it is possible to prevent the backward operation portion 5a from being well resisted by the pressing force and falling off.

  In the example shown in the figure, the notch shape portion 6c and the notch portion 5b are used in combination, so that the stability of the stopper 6 in the mounted state is further increased, and whether or not they are in the circumferential direction of the abutting end 6b of the stopper 6. In addition, the instability caused by the dispersion of the mounting holding force is avoided and the stability of mounting the stopper 6 is further enhanced.

  Moreover, the stopper 6 is assumed to be connected to a part of the animal connector 1 by the rope 23 as shown in FIGS. In this way, since the stopper 6 is connected to a part of the animal connector 1, it is prevented from being inadvertently made into a single part, so that it is difficult to lose, and the connection is made by the rope 23, so Since it is not obstructed to attach or detach the stopper 6 to or from the base 3 of the main body 10 by utilizing the property, it is easy to use. Such a rope is a ball chain in the example shown in the figure, but other things such as a resin and a string that are already known to be resistant to pulling may be used. Further, the connection with the ridge 23 is made by using a connection hole 6f at a protruding portion 6d from one part of the open edge of the attachment / detachment opening 6a of the stopper 6. As a result, the stopper 6 is removed from the attachment / detachment area of the main body 10 to the base 3 and connected to the animal connector 1, so that the connection portion with the animal connection 1 is attached to and detached from the base 3 of the main body 10 of the stopper 6. The connecting portion of the stopper 6 with the rope 23 is a protruding portion 6c from one part of the open edge of the attachment / detachment opening 6a, so that the connecting portion with the rope 23 becomes the stopper 6 The attachment / detachment of the main body 10 to / from the base 3 is not disturbed.

  In addition, the overhanging portion 6c is located in the middle of one open edge of the attachment / detachment opening 6a, so that the overhanging portion 6c is located away from both the base end side catching portion 3a of the stopper 6 and the slippery operation portion 5a. Or, it does not interfere with the attaching / detaching operation of the stopper 6 to / from the base 3 with the release of the tension. Furthermore, the attachment / detachment opening 6a of the stopper 6 is opened in a state of being separated from the side peripheral surface of the base 3 from a position exceeding the radius portion of the base 3 toward the attachment side, so that the stopper 6 is attached to the attachment / detachment opening from the anti-removal opening 6a side. The attachment / detachment resistance is reduced with the same open width, and the attachment / detachment prevention function is the same, and attachment / detachment is easier than in the case of closely contacting the side periphery of the base 3 up to 6a.
