Definitions
- the present invention describes a magnet assisted quick connect—quick disconnect mechanism for quickly, easily, and securely attaching and detaching two devices.
- Quick connect-quick disconnect mechanisms for connecting and disconnecting two devices together are known in the art. Such mechanisms are known to include magnets for securing devices together by way of magnetic forces. Examples of such mechanisms are disclosed in U.S. Pat. Nos. 3,589,341; 4,480,361; 4,4941,236 and 5,432,986. Such mechanisms are known to be used in a wide variety of applications. For example, US Pat. Nos. 4,941,236 and 5,432,986 illustrate the use of such mechanisms in jewelry applications. U.S. Pat. No. 4,480,361 discloses the use of such a mechanism in an application of magnetic clasp, for example, used as a clasp for a purse. U.S. Pat. No. 3,589,341 discloses the use of such a mechanism for use on a pet collar.
- the mechanisms disclosed above rely exclusively on the magnetic attraction forces provided by the magnets to maintain the connection between the two devices connected together by the mechanism. In such applications no external forces are anticipated during normal conditions that will oppose the magnetic attraction forces and pull the devices apart. Thus, in such applications the magnetic attraction forces provided by the magnets is sufficient to secure the two devices together for the intended application.
- the '437 device includes a two part connector. A first part is secured to an animal collar, for example, by a cord. A second part includes a ring for connection to an animal leash. Each part includes a magnet for initially connecting the two parts together in a first position.
- the first and second parts are configured so that the external tension causes the second part to move to a second position with respect to the first part.
- the first part and the second part are configured so that the tension in the second position, the first and second parts are mechanically interlocked together so that increased tension will be opposed by the mechanical interlocking.
- the two part connector discussed above provides satisfactory performance in such an application, it can only provide mechanical interlocking that opposes external forces in one direction.
- the mechanism discussed above can only provide mechanical interlocking when the tension force is in a direction away from the connector. No mechanical interlocking is provided in applications when the tension force is in a direction toward the connector. In fact, forces in that direction are used for disconnecting the two parts of the connector.
- the grabber is the female portion of the device, and is attached to a leash, for example.
- the dangle is the male portion of the device and may be attached to an animal collar.
- the grabber and the dangle each contain one permanent magnet each, which aligns and initially attaches the two components.
- the dangle is pulled into a cavity of the grabber, at which point two spring-loaded claws grab hold of the dangle securely.
- a button or slide is pressed, which opens the jaws and allows the two components to be separated.
- Both the grabber and dangle have magnets for pulling and guiding the dangle into the cavity of the grabber, at which point the claws engage to securely retaining the dangle in the cavity. This allows the leash to be attached more easily to the animal with one hand, and detached with the push of a button.
- the process of connection and disconnection require significantly less dexterity and time with the invention.
- a feature of the invention is that the user is able to more easily release the animal while the leash is under tension.

- the first portion 120 of the housing 116 defines a cavity 126 dimensioned for receiving a button 128 .
- An axial opening 130 in the first portion 120 of the housing 116 slidingly accommodates a center plunger 132 of the button 128 .
- a button spring 134 disposed on the plunger 132 biases the button 128 to a rest position.
- the button 128 has a radially outwardly projecting keeper 136 which, in the rest position, engages an interior surface 137 to retain the button 128 in the housing 116 .
- the plunger 132 projects through the opening 130 into a main chamber 138 in the housing 116 .
- Attached to the housing 116 are two arms 139 , each located in the main chamber 138 and having a free end 140 with a claw 142 , a pivot point 144 with a beak 148 , and a shoulder 150 generally between the free end and the pivot point.
- a single arm 139 is also contemplated.
- the arms 139 are made of aluminum.
- the arms 139 can be made from a variety of other metal and non-metal materials as known in the art. Impinging on the beaks 148 and the arms 139 are rubs 153 with guide arms 115 which are both part of the plunger body 132 .
- the area between the main chamber 138 of the grabber 112 and the second cavity 178 of the grabber 112 contain a pocket 117 in which resides a permanent grabber magnet 186 .
- the grabber magnet 186 is in the shape of a doughnut or ring so that the plunger 132 may pass through it and assist in pushing out the dangle 114 in the release cycle. Locating pins 172 help to align the the two halves of the grabber 112 body when it is assembled.
- the button spring 134 biases the plunger away from the second cavity 178 and engages the rubs 153 against the beaks 148 , pushing them towards the button 128 , keeping the arms 139 in a closed position.
- This closed position is the natural state for the grabber 112 whether the grabber 112 is already latched to a dangle 114 or waiting for a dangle 114 to be latched.
- the dangle 114 has shoulders 180 and guidance shapes 182 , which guide the dangle 114 into the second cavity 178 .
- a second loop 184 is attached with a split ring or the like to the collar of an animal (not pictured), is attached to the dangle 114 via insert molding, a chemical adhesive, or the like. While depicted as a semi circle, it is contemplated that the second loop 184 can be a full circle, any partially circular shape or the like.
- the dangle 114 contains a permanent magnet 185 in the shape of a doughnut or ring with a beveled hole to accept a flat head screw 190 for attachment to the dangle 114 .
- the permanent magnet 185 may also be a thin circular disc without a hole and which is held in place with adhesive (tape, epoxy or the like).
- the magnet and screw head may be covered with a sticker 187 or the like for cosmetic appearance.
- Dangle Release Cycle When the user wants to release the already latched dangle 114 , the user presses the button 128 to release the dangle 114 . When the button 128 is pressed, the plunger rubs 153 contact the shoulders 150 causing the arms 139 to pivot outward and the jaws 142 to spread apart so that the dangle 114 is released from the jaws 142 . Stops 116 prevent the arms 139 from spreading further than necessary. As the plunger 132 extends further into the main chamber 138 , the farther portion of the plunger 18 pushes through the hole in the grabber magnet 186 to eject the dangle, lessening the magnetic attraction force between grabber magnet 186 and dangle magnet 185 . The dangle 114 can thus be easily removed from the grabber 112 . The released state is shown in FIG. 14 and the fully pressed button 128 state is shown in FIG. 15 .

Abstract
The present invention relates to a two part quick connect-quick disconnect connector, which includes two parts, identified as a first part or “grabber” and a second part identified as a “dangle”. More specifically, the grabber is the female portion of the device, and is attached to a leash, for example. The dangle is the male portion of the device and may be attached to an animal collar. At least one of the grabber and the dangle may contain a permanent magnet, which aligns and initially attracts the two components to be joined together. The dangle is pulled into a cavity of the grabber, at which point two spring-loaded claws grab hold of the dangle securely. To release the device, a button or slide is pressed, which opens the jaws and allows the two components to be separated.
Description
- This application claims priority to and claims the benefit of U.S. Provisional Patent Application No. 61/588,295, filed on Jan. 19, 2012 and U.S. Provisional Patent Application No. 61/701,684, filed on Sep. 16, 2012, both hereby incorporated by reference.
- 1. Field of the Invention
- The present invention describes a magnet assisted quick connect—quick disconnect mechanism for quickly, easily, and securely attaching and detaching two devices.
- 2. Description of the Prior Art
- Quick connect-quick disconnect mechanisms for connecting and disconnecting two devices together are known in the art. Such mechanisms are known to include magnets for securing devices together by way of magnetic forces. Examples of such mechanisms are disclosed in U.S. Pat. Nos. 3,589,341; 4,480,361; 4,4941,236 and 5,432,986. Such mechanisms are known to be used in a wide variety of applications. For example, US Pat. Nos. 4,941,236 and 5,432,986 illustrate the use of such mechanisms in jewelry applications. U.S. Pat. No. 4,480,361 discloses the use of such a mechanism in an application of magnetic clasp, for example, used as a clasp for a purse. U.S. Pat. No. 3,589,341 discloses the use of such a mechanism for use on a pet collar.
- The mechanisms disclosed above rely exclusively on the magnetic attraction forces provided by the magnets to maintain the connection between the two devices connected together by the mechanism. In such applications no external forces are anticipated during normal conditions that will oppose the magnetic attraction forces and pull the devices apart. Thus, in such applications the magnetic attraction forces provided by the magnets is sufficient to secure the two devices together for the intended application.
- However, other applications exist in which one or both of the devices connected together maybe subject to external forces that oppose the magnetic attraction forces. In such applications, the magnetic attraction forces are not sufficient to maintain the connection between the two devices. In such applications, such mechanisms must include means for opposing the external forces. One such application is to use the mechanism to connect an animal collar to a leash. In such an application, the animal is known to increase the tension in the leash and exert external forces that are sufficiently greater than the magnetic attraction forces to cause the leash to become disconnected from collar.
- Conventional animal leashes are known to be connected to an animal collar with a clip that is attached to the collar directly or to a ring secured to the collar are not subject to becoming disconnected based upon increased tension on the leash. However, conventional methods for securing a leash to an animal collar require two hands to reliably engage and disengage the leash; one to hold the animal and/or its collar, and the other to operate the clip and attach/detach the hook clip with the collar. The connection process also requires a fair degree of manual dexterity, and may be difficult for disabled people, the very young and very old. Connecting is often difficult when an animal is excited. Disconnecting the leash becomes a more difficult and slow process when the leash is tensioned, for example when the animal is active and attempting to chase another animal. Additionally, the process is made difficult when the owner is wearing gloves, including when the owner takes the animal for a walk in the winter.
- As such, quick connect mechanisms for use in applications in which external forces are anticipated to be greater than the magnetic attraction forces of the magnets in the quick connect mechanism. In such mechanisms, mechanical interlocks have been provided as part of the quick connect mechanism. The mechanical interlocks are configured to oppose external forces to prevent disconnection of the mechanism when external forces are applied. An example of such a mechanism is disclosed in U.S. Pat. No. 6,499,437. The '437 device includes a two part connector. A first part is secured to an animal collar, for example, by a cord. A second part includes a ring for connection to an animal leash. Each part includes a magnet for initially connecting the two parts together in a first position. As tension is increased on the leash by the animal, the first and second parts are configured so that the external tension causes the second part to move to a second position with respect to the first part. The first part and the second part are configured so that the tension in the second position, the first and second parts are mechanically interlocked together so that increased tension will be opposed by the mechanical interlocking.
- Although the two part connector discussed above provides satisfactory performance in such an application, it can only provide mechanical interlocking that opposes external forces in one direction. In particular, the mechanism discussed above can only provide mechanical interlocking when the tension force is in a direction away from the connector. No mechanical interlocking is provided in applications when the tension force is in a direction toward the connector. In fact, forces in that direction are used for disconnecting the two parts of the connector.
- Thus, there is a need for providing a quick connect, quick disconnect mechanism that securely couples two devices together irrespective of the direction of any external forces.
- The above-listed needs are met or exceeded by the present two part quick connect-quick disconnect connector, which includes two parts, identified as a first part or “grabber” and a second part identified as a “dangle”. More specifically, the grabber is the female portion of the device, and is attached to a leash, for example. The dangle is the male portion of the device and may be attached to an animal collar. The grabber and the dangle each contain one permanent magnet each, which aligns and initially attaches the two components. The dangle is pulled into a cavity of the grabber, at which point two spring-loaded claws grab hold of the dangle securely. To release the device, a button or slide is pressed, which opens the jaws and allows the two components to be separated.
- Both the grabber and dangle have magnets for pulling and guiding the dangle into the cavity of the grabber, at which point the claws engage to securely retaining the dangle in the cavity. This allows the leash to be attached more easily to the animal with one hand, and detached with the push of a button. The process of connection and disconnection require significantly less dexterity and time with the invention. Additionally, a feature of the invention is that the user is able to more easily release the animal while the leash is under tension.

The quick release mechanism also includes a release assembly that includes a release button that allows the latch mechanism to be released when the release button is depressed.
- Referring to
FIGS. 1-4 , a quick connect-quick disconnect connector shown in an application as a pet leash connector for attaching a leash to an animal is generally designated 10. Referring now toFIG. 5 , thepet leash connector 10 is provided in two parts and includes a first part orgrabber 12 and a second part or dangle orcollar attachment 14. Thegrabber 12 has ahousing 16 securely connected to a first external interface, such as aloop 18, for example, a split ring, used to attach thegrabber 12 to a leash (not pictured). While depicted as a semi-circle, it is contemplated that thefirst loop 18 can be a full circle, any partially circular shape or the like. Secure attachment of thefirst loop 18 to afirst portion 20 of thehousing 16 is accomplished via insert molding, capture, a chemical adhesive, or the like. Opposite thefirst loop 18, thehousing 16 is configured for receiving thecollar attachment 14 or second part. - The
first portion 20 of thehousing 16 defines anannular groove 22 bordered by a radially inwardly projectingrib 24. Also defined by therib 24 is acavity 26 dimensioned for receiving abutton 28. Anaxial opening 30 in thefirst portion 20 of thehousing 16 slidingly accommodates acenter pillar 32 of thebutton 28. Abutton spring 34 disposed on thepillar 32 biases thebutton 28 to a rest position. Additionally, thebutton 28 has a radially outwardly projectingkeeper 36 which, in the rest position, engages aninterior surface 37 of the radially inwardly projectingrib 24 to retain thebutton 28 in thehousing 16. When the user presses thebutton 28 and overcomes the force of thebutton spring 34, thepillar 32 projects through theopening 30 into amain chamber 38 in thehousing 16. - Attached to the
housing 16 is a latch mechanism that includes at least one pivotally mountedarm 39. The pivotally mountedarm 39 is located in themain chamber 38 and is formed with afree end 40 with aclaw 42, apivot point 44 at anopposite end 46 with abeak 48, and alug 50 generally between the free end and the pivot point.Dual arms 39 are also contemplated as shown in the drawing. In one embodiment of the invention, thearms 39 may be made of aluminum. However, thearms 39 can be made from a variety of other metal and non-metal materials as known in the art. Attached to thebeaks 48 of thearms 39 is awasher 52 with ashaft 53. Anarm spring 54 is disposed on theshaft 53. The shaft engages thesecond portion 56 of thehousing 16 to retain thearm spring 54 in position in themain chamber 38. - Under normal conditions, i.e. when pressure has not been applied to the
button 28, thearm spring 54 acts as a biasing spring pushes against asecond portion 56 of thehousing 16, providing a bias which engages thebeaks 48, pushing them towards thebutton 28, keeping thearms 39 in a closed position. - When the
button 28 is pressed by the user to retain thecollar attachment 14, thepillar 32 extends through theopening 30 to contact thebeaks 48. As thepillar 32 extends further into themain chamber 38, thearm spring 54 is compressed as theshaft 53 is pushed through thewasher 52, and thearms 39 pivot outwardly about the pivot points 44 (shown inFIG. 6 ). - Also disposed in the
second portion 56 of thehousing 16 is aslider spring 58 which biases aslider 60 to a rest position. Theslider 60 is reciprocally located within themain chamber 38. Afirst end 62 of theslider 60 defines a U-shaped recess bordered by spacedarms 64 which slidingly engagewalls 66 of thesecond housing portion 56. Two radially outwardly projectingtabs 68 of theslider 60 push against thelugs 50 of thearms 39. Additionally, twostops 70 engage opposite ends 72 of theslider 60, respectively, and oppose the bias of theslider spring 58 while theslider 60 is in the rest position. The stops 70 are located on athird portion 74 of thehousing 16. - A
second cavity 78 in the first part, which receives the second part orcollar attachment 14, is defined by thethird portion 74 of thehousing 16 and thestops 70. Thus, theslider 60 reciprocates axially relative to the second 56 and third 74 housing portions. - The
collar attachment 14 hasshoulders 80 and guidance shapes 82, which guide thecollar attachment 14 into thesecond cavity 78. A second external interface, such as asecond loop 84, for example, a split ring attached to the collar of an animal (not pictured), may be securely attached to the second part orcollar attachment 14 via insert molding, a chemical adhesive, or the like. While depicted as a semicircle, it is contemplated that thesecond loop 84 can be a full circle, any partially circular shape or the like. - Referring now to
FIG. 6 , when thecollar attachment 14 is placed in thesecond cavity 78, theshoulders 80 of thecollar attachment 14 push the spacedarms 64 of theslider 60 as the slider progresses towards thebutton 28 and the spaced arms slidingly engage thewalls 66 of thesecond housing portion 56. Once thelugs 50 of thearms 39 engage the radially outwardly projectingtabs 68 of theslider 60, thearms 39 pivot radially inward and rest against thestops 64. Theclaws 42 of thearms 39 clip around theshoulder 80 of thecollar attachment 14, securing thecollar attachment 14 into thesecond cavity 78 defining a latched position. Thus, thecollar attachment 14 is latched in place. - A button assembly which includes a
button 28, allows a user to release the first part from the second part, for example, release the pet collar from the leash, thebutton 28 is depressed. Thepillar 32 extends through theopening 30 to contact thebeaks 48. As thepillar 32 extends further into themain chamber 38, thearm spring 54 is compressed as theshaft 53 is pushed through thewasher 52 and thearms 39 pivot outwardly about the pivot points 44. With theclaws 42 of thearms 39 no longer clipped around theshoulders 80 of thecollar attachment 14, the bias of theslider spring 58 pushes theslider 60 away from thebutton 28, and thecollar attachment 14 is pushed away from thebutton 28 and out of thesecond cavity 78. - In an alternate embodiment of the invention shown in
FIGS. 5 and 6 , afirst magnet 86 may be affixed to the first part and specifically third portion of thehousing 80 via a chemical adhesive or the like. Additionally, the second part orcollar attachment 14 may be provided with asecond magnet 88. The attraction between the poles of first 86 and thesecond magnet 88 guide and engage thecollar attachment 14 into thesecond cavity 78. - Referring to
FIGS. 7-10 , a pet leash connector for attaching a leash to an animal is generally designated 10. Referring now toFIGS. 11 and 12 , thepet leash connector 110 is provided in two parts and includes agrabber 112 and adangle 114. - Grabber Description: The
grabber 112 has ahousing 116 connected to afirst loop 118, such as a wire-formed ring used to attach thegrabber 112 to a leash (not pictured). While depicted as a semicircle, it is contemplated that thefirst loop 118 can be a full circle, any partially circular shape, a circular shape with a flat portion, or the like or may also be a permanent part of thegrabber 112. Attachment of thefirst loop 118 to afirst portion 120 of thehousing 116 is accomplished via insert molding, mechanical capture, a chemical adhesive, or the like. Opposite thefirst loop 118, thehousing 116 is configured for receiving thedangle 114. - The
first portion 120 of thehousing 116 defines acavity 126 dimensioned for receiving abutton 128. Anaxial opening 130 in thefirst portion 120 of thehousing 116 slidingly accommodates acenter plunger 132 of thebutton 128. Abutton spring 134 disposed on theplunger 132 biases thebutton 128 to a rest position. Additionally, thebutton 128 has a radially outwardly projectingkeeper 136 which, in the rest position, engages aninterior surface 137 to retain thebutton 128 in thehousing 116. When the user presses thebutton 128 and overcomes the force of thebutton spring 134, theplunger 132 projects through theopening 130 into amain chamber 138 in thehousing 116. - Attached to the
housing 116 are twoarms 139, each located in themain chamber 138 and having afree end 140 with aclaw 142, apivot point 144 with abeak 148, and ashoulder 150 generally between the free end and the pivot point. Asingle arm 139 is also contemplated. In a preferred embodiment of the invention, thearms 139 are made of aluminum. However, thearms 139 can be made from a variety of other metal and non-metal materials as known in the art. Impinging on thebeaks 148 and thearms 139 arerubs 153 withguide arms 115 which are both part of theplunger body 132. - The area between the
main chamber 138 of thegrabber 112 and thesecond cavity 178 of thegrabber 112 contain apocket 117 in which resides apermanent grabber magnet 186. In a preferred embodiment of the invention thegrabber magnet 186 is in the shape of a doughnut or ring so that theplunger 132 may pass through it and assist in pushing out thedangle 114 in the release cycle. Locatingpins 172 help to align the the two halves of thegrabber 112 body when it is assembled. - Under normal conditions, i.e. when pressure has not been applied to the
button 128, thebutton spring 134 biases the plunger away from thesecond cavity 178 and engages therubs 153 against thebeaks 148, pushing them towards thebutton 128, keeping thearms 139 in a closed position. This closed position is the natural state for thegrabber 112 whether thegrabber 112 is already latched to adangle 114 or waiting for adangle 114 to be latched. - Dangle Description: The
dangle 114 hasshoulders 180 and guidance shapes 182, which guide thedangle 114 into thesecond cavity 178. Asecond loop 184, is attached with a split ring or the like to the collar of an animal (not pictured), is attached to thedangle 114 via insert molding, a chemical adhesive, or the like. While depicted as a semi circle, it is contemplated that thesecond loop 184 can be a full circle, any partially circular shape or the like. In a preferred embodiment of the invention, thedangle 114 contains apermanent magnet 185 in the shape of a doughnut or ring with a beveled hole to accept aflat head screw 190 for attachment to thedangle 114. However, thepermanent magnet 185 may also be a thin circular disc without a hole and which is held in place with adhesive (tape, epoxy or the like). The magnet and screw head may be covered with asticker 187 or the like for cosmetic appearance. - Dangle Release Cycle: When the user wants to release the already latched
dangle 114, the user presses thebutton 128 to release thedangle 114. When thebutton 128 is pressed, the plunger rubs 153 contact theshoulders 150 causing thearms 139 to pivot outward and thejaws 142 to spread apart so that thedangle 114 is released from thejaws 142.Stops 116 prevent thearms 139 from spreading further than necessary. As theplunger 132 extends further into themain chamber 138, the farther portion of theplunger 18 pushes through the hole in thegrabber magnet 186 to eject the dangle, lessening the magnetic attraction force betweengrabber magnet 186 anddangle magnet 185. Thedangle 114 can thus be easily removed from thegrabber 112. The released state is shown inFIG. 14 and the fully pressedbutton 128 state is shown inFIG. 15 . - Dangle Latch Cycle. As the
dangle 114 moves in proximity of thesecond cavity 178, thedangle magnet 185 andgrabber magnet 186 begin to attract. This magnetic attraction begins to forcefully convey thedangle 114 into thegrabber cavity 178. As thedangle 114 meets thejaws 142 of thearms 139, the magnetic attraction pulls thedangle 114 into thecavity 178 which spreads thejaws 142 open, causing thebeaks 148 of thearms 139 to press against the plunger, thereby overcoming the force of thespring 134. As thedangle 114 continues into thecavity 178 of the grabber so that theshoulder 180 of thedangle 114 moves inward past thejaws 142 of thegrabber 112, thejaws 142 are no longer held open by thedangle 114 and thespring 134 force on thebeaks 148 causes the arms to return to their resting position thereby latching thedangle 114. The latched state is shown inFIG. 13 . - Referring to
FIGS. 16-19 , a pet leash connector for attaching a leash to an animal is generally designated 10. Referring now toFIGS. 20 and 21 , thepet leash connector 210 is provided in two parts and includes agrabber 212 and adangle 214. - Grabber Description: The
grabber 212 has ahousing 216 connected to afirst loop 218, such as a wire-formed ring used to attach thegrabber 212 to a leash (not pictured). While depicted as a D-ring, it is contemplated that thefirst loop 218 can be a full circle, any partially circular shape, a circular shape with a flat portion, or the like or may also be a permanent part of thegrabber 212. Attachment of thefirst loop 218 to afirst portion 220 of thehousing 216 is accomplished via insert molding, mechanical capture, a chemical adhesive, or the like. Opposite thefirst loop 218, thehousing 216 is configured for receiving thedangle 214. - The
first portion 220 of thehousing 216 defines acavity 226 dimensioned for receiving abutton 228. Twoopenings 180 degrees opposed expose thebutton 228 on either side of thegrabber 212 in thefirst portion 220 of the housing for ease of accessibility to thebutton 228 by the user from either side of thegrabber 212. Abutton spring 234 disposed on thebutton 228 biases thebutton 228 to a rest position. When the user slides thebutton 228 forward and overcomes the force of thebutton spring 234, a dangle release cycle is initiated, described later in the text. - Attached to the
housing 216 are twoarms 239, each having afree end 240 with aclaw 242, apivot point 244 with abeak 248, and ashoulder 250 generally between the free end and the pivot point. Asingle arm 239 is also contemplated. In a preferred embodiment of the invention, thearms 239 are made of aluminum. However, thearms 239 can be made from a variety of other metal and non-metal materials as known in the art. Impinging on thebeaks 248 and thearms 239 arerubs 253 built as part of thebutton 228. - The area between the
main chamber 238 of thegrabber 212 and thesecond cavity 278 of thegrabber 212 contain apocket 217 in which resides apermanent grabber magnet 286. In a preferred embodiment of the invention thegrabber magnet 186 is in the shape of a solid disc. - Under normal conditions, i.e. when pressure has not been applied to the
button 228, thebutton spring 234 biases thebutton 228 against thebeaks 248 of thearms 239, keeping thearms 239 in a closed position. This closed position is the natural state for thegrabber 212 whether thegrabber 212 is already latched to adangle 214 or waiting for adangle 214 to be latched. - Dangle Description: The
dangle 214 hasshoulders 280 and guidance shapes 282, which guide thedangle 214 into thesecond cavity 278. Asecond loop 284, is attached with a split ring or the like to the collar of an animal (not pictured), is attached to thedangle 214 via insert molding, a chemical adhesive, or the like. While depicted as a semi circle, it is contemplated that thesecond loop 284 can be a full circle, any partially circular shape or the like. In a preferred embodiment of the invention, thedangle 214 contains apermanent magnet 285 in a solid thin disc shape which is held in place with adhesive (tape, epoxy or the like). - Dangle Release Cycle: When the user wants to release the already latched
dangle 214, the user slides thebutton 228 in the direction of the dangle to release thedangle 214. When thebutton 228 is slid, the button rubs 253 contact theshoulders 250 causing thearms 239 to pivot outward and thejaws 242 to spread apart so that thedangle 214 is released from thejaws 242.Stops 216 prevent thearms 239 from spreading further than necessary. Thedangle 214 can thus be easily removed from thegrabber 212. The released state is shown inFIG. 23 and the fully slid releasedbutton 228 state is shown inFIG. 24 . - Dangle Latch Cycle: As the
dangle 214 moves in proximity of thesecond cavity 278, thedangle magnet 285 andgrabber magnet 286 begin to attract. This magnetic attraction begins to forcefully convey thedangle 214 into thegrabber cavity 278. As thedangle 214 meets thejaws 242 of thearms 239, the magnetic attraction pulls thedangle 214 into thecavity 278 which spreads thejaws 242 open, causing thebeaks 248 of thearms 239 to press against thebutton 228, thereby overcoming the force of thespring 234. As thedangle 214 continues into thecavity 278 of the grabber so that theshoulder 280 of thedangle 214 moves inward past thejaws 242 of thegrabber 212, thejaws 242 are no longer held open by thedangle 214 and thespring 234 force on thebeaks 248 causes the arms to return to their resting position thereby latching thedangle 214. The latched state is shown inFIG. 22 . - Alternate Dangle Design:
FIG. 25 shows an alternate version of the dangle, with an integratedspring wire clip 390. This alternate dangle design could be used for less permanent applications, where ease of attaching and removing the dangle is required. - The
alternate dangle 314 hasshoulders 380 and guidance shapes 382, which guide thedangle 314 into thesecond cavity 278 of thegrabber 212 similarly to the way dangle 214 is guided. A hook feature, 384, in conjunction with aspring wire 390 is latched onto the collar ring of an animal (not pictured), and is retained byspring wire 390.Dangle 314 allows for less side to side motion thandangle 214 and reduces the possibility of thedangle magnet 385 becoming affixed to other magnetic metal objects, such as tags, hanging off the collar which can impede the attachment of thegrabber 212 to thedangle 314. In a preferred embodiment of the invention, thedangle 314 contains apermanent magnet 385 in a solid thin disc shape which is held in place with adhesive (tape, epoxy or the like). - Obviously, many modifications and variations of the present invention are possible in light of the above teachings. Thus, it is to be understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically described above.
