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. 7 to 9, the animal connector particularly includes a base part b1 connected to a base end ring a and the base part 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 connection tool k connected to the mooring string j or the like has the anchor part 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. 7, 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 A catching force and a pushing force to the backward operation side of the backward operation portion c1 of the locking pin d of k are inadvertently acted, and the opening portion b4 of the hook portion b2 is opened and connected to the hook portion b2 as shown in FIG. It sometimes happens that the connection with the ring g or the like is broken. Here, FIG. 8 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 3 are configured so that even if the connecting ring g is twisted, the hooks are prevented from being hooked 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, in the technique disclosed in Patent Document 1, one additional part is a connecting ring. However, since two operations for connecting the connecting ring to the connecting parts on both sides are necessary, the cost increases. In addition, with the techniques disclosed in Patent Documents 2 and 3, a special product that is difficult to form and assemble becomes expensive.

  The present invention has been made in view of such problems, and is a low-cost animal that can prevent unintentional disconnection without the addition of a part or with the addition of one part that can be easily mounted. It is an object to provide a connector for use.

A main body having a base connected to the base end ring and a hook portion extending from the base, and a closing behavior that closes the opening of the hook portion by being spring-biased in the base and projecting and pressing the tip of the hook portion And a locking pin having an operation part that is operated to move backward around the base against the spring, and the operation part is provided on the base peripheral wall on the opening part side of the hook part. The base end ring is formed by a connecting hole at the center of the connecting end, and is formed so as to extend from the rising portion rising from the outer periphery of the locking pin to the outer periphery of the base through the slide groove. The connecting end is connected to the connecting shaft so as to be rotatable around the axis, and the connecting end is opposed to the retreating side end portion of the operation unit at a specific rotation position, and allows the operation unit to retreat. Abut the locking pin in the closed position Tsu is the one wherein a click is sized and shaped to prevent retraction.

In such a configuration, in an animal connector of a normal form provided with a main body and a locking pin, an operation portion provided for the locking pin is provided on the opening portion side of the hook portion of the base peripheral wall of the main body. The operation part does not become bulky around the base part from the rising part rising from the outer periphery of the locking pin through the slide groove to one or both of the circumferential direction along the outer periphery of the base part. It becomes difficult to get caught in the connection partner even if it falls between. In addition, the operation part is easy to be retracted by obtaining a wide back area, side edge area, hook side tip thickness area without increasing bulk around the base part, and the hook part opening part side by the slide groove of the base peripheral wall A hand that extends from the rising part located on the base to one or both sides in the circumferential direction of the base, and grips the proximal end ring-side connecting part with the open side of the hook part or the opposite back side between the thumb and the index finger valley With the thumb and / or index finger of the wrist, the hook side tip thickness area, the back area, or the side edge area is retracted by accessing from the open side or the back side of the hook part, and the wrist to the non-access side as it is The hook part can be connected to or disconnected from the connection partner by the internal swing behavior or the external swing behavior. In addition, the base ring is made artificially easy, and an unintentional reverse operation force works on the operation part that is hard to catch, and it is very unlikely that it will happen artificially. When the actuator is in the relative rotational position, the operation part is allowed to move backward, and at other rotational positions, the locking pin is locked in the closed position to prevent the backward operation, so there is no need for an operating part without an accessory member. It is possible to prevent the reverse operation with high probability.

  In the above, the operation part can be further fitted in the hollow part of the outer periphery of the base part. In such a configuration, the operation part is less likely to be caught by the connection partner due to the twisting with the connection partner according to the degree to which the operation part does not protrude to the outer periphery of the base by fitting into the recess of the base outer periphery. Even if the back area is flush with the outer periphery of both sides of the recess of the base, it is advantageous to avoid catching and the thickness area is open to the hook side end of the base, and the finger is hooked by opening to the hook side end of the base Reverse operation can be performed without difficulty. For this purpose, it is preferable that the operating portion is extended to the extent that it is substantially along the open portion side of the hook portion on the outer periphery of the base portion. However, it is also possible to perform the backward operation by providing the back surface area of the operation unit with a non-slip shape or surface state.

  In the above, the base further includes a stopper member fitted so as to be able to move in the circumferential direction around the side where the operation portion of the base is retracted, and the stopper member has a base end flange portion and an operation portion at a circumferential lock position. There is a stopper part that locks the locking pin in the closed position via the tension operation part to prevent retraction, and the locking pin is unlocked by moving from the locked position to the unlocked position in the circumferential direction Can be. In such a configuration, in addition to the above, the stopper member does not need to be attached / detached depending on the movement position around the base portion, and the locking pin is locked at the closed position via the operation portion to prevent the backward operation, and the lock is released. Therefore, it is possible to adopt a mounting structure in which the stopper member is not inadvertently dropped off.

  The animal connector of the present invention also includes a main body having a base portion connected to the base end ring and a hook portion extending from the base portion, is spring-biased in the base portion, protrudes, and presses against the tip of the hook portion. In the connection tool for animals, which has a closing behavior that closes the opening part of the hook part, and an operation part that protrudes backward against the spring and protrudes around the base part, the proximal ring is connected It is connected so that it can rotate around the axis of connection with the connecting shaft of the base at the connecting hole in the center of the end, and the connecting end allows the operating portion to retreat in opposition to the retreating side end of the operating portion at a specific rotational position. Another feature is that it has a size and shape that abuts against the operating portion at other rotational positions and locks the locking pin in the closed position to prevent retraction.

  In such a configuration, in the animal connector having the main body and the locking pin in the normal form, the rotatable connecting end with the base portion of the base end ring is connected to the retreat side end of the operating portion at a specific rotational position. The operation part is allowed to move backward in opposition to the part, and in other rotation positions, the operation part is brought into contact with the operation part and the locking pin is locked in the closed position to improve the size and shape to prevent the backward movement. The base ring is artificially made easy, the connection partner should be caught in the operation part, and an inadvertent reversing operation force works, and the non-artificial probability is very low. When the actuator is in a specific relative rotational position, the operation unit is allowed to move backward, and at other rotation positions, it is locked at the closed position to prevent the backward movement. It can be stopped with a high probability.

  Simple and inexpensive structure that only improves the operation part provided on the locking pin from the rising part from the outer periphery of the locking pin to one or both of the circumferential direction along the outer periphery of the base. It will not be bulky, and it will be harder to catch the connection partner even if it is twisted with the connection partner. In addition, the operation part is easy to be retracted by obtaining a wide back area and thickness area without increasing bulk around the base part, and from the rising part located on the open part side of the hook part by the slide groove of the base peripheral wall, By the thumb and / or index finger of the hand that extends to one or both sides of the base circumferential direction and holds the base ring-side connecting portion facing the open side of the hook part or the back side opposite to the valley between the thumb and the index finger, The hook side tip thickness area, the back area, or the side edge area is retracted by accessing from the open or back side of the hook part, that is, from the access side using the retracting operation force to the non-access side The hook part can be connected to and released from the connecting partner easily and quickly by the inner swinging behavior or the outer swinging behavior of the wrist.

  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, the second example connector 200 shown in FIG. 2, the example connector 300 shown in FIG. 3, the example connector 400 shown in FIG. 4, and FIG. 5. Both the example connector 500 and the example connector 600 shown in FIG. 6 have a base body 2 connected to the base end ring 1 made of metal and a metal main body provided with a hook portion 3 extending from the base portion 2. 4 and a spring 5 which is urged by a spring 5 shown representatively in FIG. 1 (a) in the base portion 2 and has a closing habit to close the opening portion 6 of the hook portion 3 by pressing and contacting the tip 3a of the hook portion 3. 5 and a metal locking pin 8 having an operation portion 7 which is operated to move backward around the base portion 2. As a result, each of the couplers 100, 200, 300, 400, 500, and 600 allows the locking pin 8 to be moved by the operation portion 7 as shown in FIGS. 1 (a), 2 (a), 3, 4 (a), 5 (a) and FIG. 6 (a), the opening portion 6 of the hook portion 3 is moved backward from the closed position shown in FIG. 1 (b), FIG. 2 (b), FIG. 4 (b), FIG. (B) It can be opened as shown in FIG. 6 (b), and can be in a state of being detachable from the connection partner. When the operating portion 7 is released from the retreating operation, the locking pin 8 is returned to the closed position by the spring 5 and comes into contact with the tip 3a of the hook portion 3, so that the releasing portion of the hook portion 3 is closed and the connected state is established at the time of connection. It will be in the state to maintain.

  However, when an animal such as a dog using the connector 100, 200, 300, 400, 500, 600 is brought or moored, if the connector is drowned due to an abnormal operation when the animal is surprised, the operation unit 7 In rare cases, an inadvertent reverse operation force acts, and the opening 6 of the hook 3 is opened and the connection is released.

  Correspondingly, the connecting tool 100 shown in FIG. 1 is configured such that the operating portion 7 is moved from the outer periphery of the locking pin 8 through the slide groove 11 provided on the opening portion 6 side of the hook portion 3 on the base 2 peripheral wall. It is formed so as to extend in one or both of the circumferential directions along the outer periphery of the base portion 2 from the rising portion 8a shown as a representative in FIG. Thus, in the animal connector 100 of the normal form provided with the main body 4 and the locking pin 8, the operation part 7 provided in the locking pin 8 is used for the hook part 3 of the base 2 peripheral wall of the main body 4. The operation portion is improved by extending from the rising portion 8a rising from the outer periphery of the locking pin 8 to the outer periphery of the base portion 2 through the slide groove 11 provided on the opening portion 6 side and extending in one or both of the circumferential directions along the outer periphery of the base portion 2. 7 does not become bulky around the base portion 2, and accordingly, it is less likely to be caught by the connection partner due to a twist between the connection partner such as the D ring of the collar and the connection ring of the mooring device.

  In addition, the operating portion 7 is easily retreated around the base 2 by obtaining a wide back region 7a, side edge region 7b, and hook-side tip thickness region 7c without increasing bulk, and the slide groove 11 on the peripheral wall of the base 2 Extends from the rising portion 8a located on the opening portion 6 side of the hook portion 3 to one or both sides in the circumferential direction of the base portion 2, and between the thumb and the index finger, the opening portion 6 side of the hook portion 3 or the back side opposite thereto The hook side tip thickness region 7c, the back surface region 7a, or the side edge region 7b is changed to the open part 6 side or the back part of the hook part 3 by the thumb and / or forefinger of the hand holding the base ring 1 side connecting part. The hook part 3 can be connected to and disconnected from the connection partner by the backward movement of the wrist by the access from the side and the movement of the wrist to the non-access side (the palm side) or the outward movement (the back of the hand).

  As a result, a simple and inexpensive structure that only improves the operation portion 7 provided in the locking pin 8 to a form extending from the rising portion 8a from the outer periphery of the locking pin 8 to one or both of the circumferential direction along the outer periphery of the base 2. Therefore, the operation part 7 does not become bulky around the base part 2, and accordingly, it becomes difficult to be caught by the connection partner even if it is twisted with the connection partner, and it is easy to prevent it from being opened carelessly. In addition, the operating portion 7 is easily retreated around the base 2 by obtaining a wide back region 7a, side edge region 7b, and thickness region 7c without increasing bulk, and the hook portion is formed by the slide groove 1 on the peripheral wall of the base 2. 3 from the rising portion 8a located on the open portion 6 side to one or both sides in the circumferential direction of the base portion 2, with the open portion 6 side of the hook portion 3 or the opposite back side facing the valley between the thumb and forefinger. Any one of the hook side tip thickness region 7c, the back surface region 7a, and the side edge region 7b from the open part 6 side or the back part side of the hook part 3 by the thumb and / or forefinger of the hand holding the base ring 1 side connection part. The hook part 3 can be easily connected to and disconnected from the connecting partner by moving the back part of the wrist as it is, that is, by using the backward movement force from the access side to the non-access side. Xun It can be performed to.

  The operation condition will be described in more detail. When the operation portion 7 extends from the rising portion 8a to one side in the circumferential direction of the base portion 2, the corresponding side of the thumb and forefinger of the hand grasping the proximal end ring 1 side connection portion. The finger is retreated by operating any one of the back area 7a, the side edge area 7b, and the hook side end thickness area 7c of the operation section 7. In this case, if a non-slip groove 12 extending in the width direction as shown in the figure on the back surface area 7a, ridges, irregularities, knurls, etc. are applied, it is possible to produce a relatively strong spring 5 simply by pressing a finger on the back surface area 7a. You can easily and reliably move backward without losing. Further, the anti-slip effect by the groove 12 or the like is also effective in the case where the side edge region 7b is put in a retreat operation on the condition that it reaches the side edge region 7b. The hook-side end thickness region 7c alone is sufficient to catch the finger and is easy to operate backwards, but it is easier to operate by sharing with the back region 7a that is anti-slip. Even in the operation of the side edge region 7b, it can be shared with the back surface region 7a. Further, when the operation portion 7 extends from the rising portion 8a to both sides in the circumferential direction of the base portion 2, the rear region 7a and the side of the operation portion 7 can be used with both the thumb and the index finger of the hand holding the proximal end ring 1 side connection portion. The retraction operation can be performed by pinching the edge region 7b from both the left and right sides, and the retraction operation can be performed by hooking the hook side end thickness region 7c from the left and right sides.

  In particular, the thumb behavior from both sides with the thumb and forefinger is not only caused to operate the operating portion 7 with a good balance between left and right, but also to be retracted, as well as the base ring 1 side connecting portion gripped by the hand. It functions to stabilize the orientation of the main body 4 in the left-right direction, and also serves as a point of action of force for connecting the hook part 3 opened by the retreating operation 6 to the connection partner and releasing the connection. The operation from the subsequent backward operation to the connection or disconnection by grasping the base end ring 1 side connection portion can be achieved smoothly and quickly.

  In addition to the case of the first example, the connection tool 200 of the second example shown in FIG. 2 is further configured such that the operation unit 7 is fitted into the recess 13 on the outer periphery of the base 2. As a result, the operation unit 7 is less likely to be caught by the connection partner due to the twisting with the connection partner according to the degree to which the operation unit 7 does not protrude from the outer periphery of the base 2 due to the fitting into the recess 13 on the outer periphery of the base unit 2. The back side area 7a is flush with the outer periphery of both sides of the recess 13 of the base 2 and the hook side tip thickness area 7c extends to the hook side end 2a of the base 2 even if it is advantageous to avoid catching as shown in FIG. The opening operation of the base portion 2, especially the opening to the hook side end portion 2 a of the base portion 2, can be performed without difficulty by hooking a finger. For this purpose, it is preferable that the operation portion 7 is extended so as to be substantially along the half-circumferential region on the opening portion 6 side of the hook portion 3 of the base portion 2 as in the illustrated example. However, the back region 7a of the operation unit 7 can be moved backward by providing a non-slip groove 12 or the like. In the example shown in the figure, a Z-shaped dividing line 14 having a step in the middle from the inner side to the outer side is provided between the contact end surfaces of the locking pin 8 and the hook part 3 so that the connecting partner is less likely to slip through the opening part 6. doing.

  A connecting tool 300 of the third example shown in FIG. 3 is replaced with a hook side end 2a instead of the recess 13 of the second connecting tool 200 opening above the hook side end 2a of the base 2. The hollow portion 15 is formed so as to be recessed to the near side. As a result, the operating portion 7 is further released from the hook-side tip thickness region 7c to the hook portion 3 side, and further away from the hook portion 3, so that the operating force can be further increased by the twisting with the connection partner. It becomes difficult to receive, and it becomes easier to avoid being opened carelessly with a simple structure. The effect of preventing the connection partner from being caught when the operation unit 7 is moved away from the hook unit 3 is also effective in other examples.

  The fourth connector 400 shown in FIG. 4 is fitted so that the operation unit 7 of the base 2 can be moved in the circumferential direction around the side where the operation unit 7 of the base 2 is retracted, in addition to the case of the connector 100 of the first example. A stopper member 21 as shown in FIG. This stopper member 21 is stretched between the base end flange 2b and the operating portion 7 at the circumferential locking position shown in FIG. A, and the locking pin 8 is locked to the closed position via the operating portion 7 to move backward. A stopper portion 21a for blocking is provided, and the locking pin 8 is locked by moving the stopper portion 21a from the lock position to the non-lock position shown in FIG. I try to release it. Accordingly, the stopper member 21 does not need to be attached / detached depending on the movement position around the base portion 2, and the locking pin 8 is locked to the closed position via the operation portion 7 to prevent the backward operation, and the lock member is released. 21 can adopt a mounting structure that does not drop carelessly.

  The stopper member 21 is made of metal or resin, and the stopper portion 21a is formed on the hook portion 2 side from a part in the circumferential direction of the ring portion 21b that is in contact with the base end flange portion 2b of the base portion 2 and is prevented from coming off from the base portion 2. It is integrally formed to extend. The ring portion 21b is formed with an open portion 21c in a part in the circumferential direction. The open portion 21c is elastically opened to fit the base portion 2 in the direction perpendicular to the axis, and then released from the opening operation, the ring portion 21b is elastically restored. Therefore, it can be retrofitted to the base part 2, and the open part 21c can be prevented from being inadvertently dropped by setting it to 1/4 or less of the circumferential direction. The smaller the width of the open portion 21c, the harder it is to come off, and the larger the size, the easier the mounting.

  In the example of the connector 500 shown in FIG. 5, the operation portion 7 of the locking pin 8 is a vertically long one that does not spread from left to right, and the retracted side end 7 d is the base end at the closed position of the locking pin 8. The connecting end 1a is positioned in contact with or close to the connecting end 1a of the ring 1. The connecting end 1a is connected to the connecting shaft 2c of the base portion 2 at the center connecting hole 1b shown in FIGS. The connecting end 1a is opposed to the retreating side end portion 7d of the operation portion 7 at a specific rotation position shown in FIGS. 5B and 5C. ), The operating unit 7 is allowed to retract from the closed position shown in FIG. 5 (a), and at other rotational positions, the operating unit 7 is shown in FIGS. 5 (a) and 5 (d). And the locking pin 8 is locked in the closed position and has a size and shape that prevents retraction. Thereby, the base end ring 1 is artificially easily made with a simple and inexpensive structure that makes the operation portion 7 longer than the conventional case and improves the form of the connecting end 1a. In the unlikely event that an inadvertent reverse operation force works, and the probability that this will occur artificially is extremely low, the reverse operation of the operation unit 7 is allowed only when it is at a specific relative rotational position with respect to the base 2. In the other rotational positions, the locking pin 4 is locked in the closed position to prevent the backward operation, so that it is easy to prevent an inadvertent backward operation of the operation unit 7 without an accompanying member.

  For this purpose, the form of the connecting end 1a can be freely set. However, in the illustrated example, the connecting end 1a of the base end ring 1 abuts the outer peripheral portion of the operating end 7 opposite to the retreating side end 7d in the axial direction. The operation part is formed in a disk-shaped part having a matching outer shape, at a specific position on the outer periphery thereof, specifically two places on the diameter line, more specifically two places on the diameter line perpendicular to the flat direction of the base end ring 1 As shown in FIG. 5B, a notch portion 31 that allows the operation portion 7 to move backward is formed. There is no special meaning in the orthogonal direction, but the cutout portion 31 in the circumferential direction of the connecting end 1a is low in volume avoiding the connecting portion with the base end ring 1, and the connecting portion has a simple form that does not disturb the connecting portion. This prevents the cutout portion 31 from reaching a complicated detour to avoid this.

  The coupling tool 600 of the example shown in FIG. 6 is the operation part 7 which the coupling tools 100, 200, 300, and 400 of the first to fourth examples employ, that is, the rising part 8a from the locking pin 8 to the base part. In the one having the operation portion 7 extending on one side or both sides in the circumferential direction along the outer periphery of 2, the lock technique in the connector 500 of the fifth example is adopted. Furthermore, the relationship between the operation part 7 and the notch part 31 at the embodiment level of the connector 500 is not substantially changed. However, the operation unit 7 is the same as the example of the couplers 100, 400, and 500 in the examples of FIGS. However, in order to lock the locking pin 8 to the closed position by contacting the base end flange 2b of the base portion 2, it is necessary to make it further downward.

  Therefore, in this example, the closing position of the operation portion 7 is further lowered from the hook side end portion 2a of the base portion 2 than in the case of the connector 300 of the example shown in FIG. It is. As a result, the operation portion 7 does not become longer and shorter, and even if the operation portion 7 is greatly distant from the hook side end portion 2a of the base portion 2, even if the operation portion 7 is drowned with the connection partner, it is further less likely to receive a reverse operation force. In addition, the function of preventing inadvertent detachment is further enhanced.

  Further, the operation portion 7 is hung from the midway portion in the vertical direction to the receding end portion 7d at the lower end to have a tapered shape, and a specific position is obtained by fitting in a small range in the circumferential direction with the cutout portion 31 having a shape conforming thereto. The backward operation of the operation unit 7 can be permitted.

  The present invention is practically used for an animal connector generally referred to as a eggplant ring, and even if a stagnation occurs with a connection partner, the operating force of the locking pin is difficult to reach, Even if it reaches, it can prevent a latching pin from retreating, and it can prevent a connection being removed carelessly.
