Description

[Technical Field]

[0001] The present invention relates to a switch clasp, which is an electrical switch capable of acting as a clasp, or a clasp capable of acting as an electrical switch. As a non-limiting example, the switch clasp may find application in clothing or a bag, where the action of opening and closing the clasp can trigger an electrical signal. The switch clasp also provides the function of a clasp that allows the clothing or bag to be fastened or fastened; for example, in a bag, the clasp may hold a closure flap in a closed position. However, the switch clasp may also serve to temporarily fasten any article or part of an article to another part of an article or any other article, and provide an indication via an electrical signal of whether the article is fastened or not. [Background technology]

[0002] Chinese Utility Model No. 210696397 discloses a magnetic clasp used to secure the closure flap of a bag, such as a shoulder bag. The clasp in Chinese Utility Model No. 210696397 includes a male part and a female assembly. The male part includes a protrusion incorporating a magnet of a first polarity and a mount for attaching the male part to a membrane, such as the closure flap, of the bag. The female assembly includes a socket incorporating a magnetic element of a second polarity and a mount for attaching the female assembly to the body of the bag. To close the flap against the body, the flap is manipulated to engage with the protrusion of the socket, where it is held by magnetic attraction. Opening the bag is easily achieved by applying sufficient force in a direction that overcomes the magnetic attraction. Chinese Utility Model No. 21069639 does not disclose an electrical switch.

[0003] There are many other known types of clasps that include male and female parts, such as "latch" and "snap" clasps, in which the male and / or female parts elastically deform to allow the male part to fit into the female part and then "snap" back to their original shape or a shape close to their original shape, thereby securing the male and female parts relative to one another. Another example clasp type is a rotor clasp, in which one of the male and / or female parts includes a "rotor" that is rotatable so that the relative positions of the male and female parts are fixed.

[0004] Clasps are used to fasten two items together. Typically, clasps are used to fasten closure flaps on bags such as handbags, shoulder bags, or backpacks. Clasps are also used to fasten opposite sides of a bag or opposite sides of a garment. Summary of the Invention [Means for solving the problem]

The fastening means can also or instead have features such as holes that may be threaded to accept screws or machine screws or rivets. The fastening structure may be adapted for fastening by adhesive or welding.

[0027] The switch clasp was originally envisioned as a fastener for a bag closure having a body and some form of closure flap, so that the items held together by the clasp would be parts of a single item, although the items to which the parts are fastened may be entirely separable.

[0028] The sensor is preferably located on only one of the first and second components. This means that electrical contacts for the sensor readout are required on only one item, minimizing the steps required to install the switch clasp and connect it to a readout device that responds to the electrical signal. A preferred form of sensor is a monostable microswitch or magnetic proximity switch, i.e., a Hall or reed switch. For some clasps, a rotary switch can be used to position the circuit normally open or closed in a first condition and close the circuit in a second condition, depending on use. The readout device will depend on the intended purpose of the switch clasp, but a light or alarm may be useful. Thus, in applications where the switch clasp is a clasp for a handbag, opening the clasp could activate a light inside the body of the bag to illuminate the contents, or the switch clasp could sound an alarm in the event of unauthorized opening.

[0031] Figure 1 shows a perspective view of a switch clasp according to a first embodiment, and Figures 2 and 3 show a side view and a side cross-sectional view of the switch clasp assembly of Figure 1, respectively.

[0032] The switch clasp of the first embodiment has a first part provided by a female assembly (also referred to as the "female part") 1 and a second part provided by a separable male part 2. The female assembly 1 comprises a housing 3, a permanent magnet 4 providing an attraction portion, a float 5, a microswitch 6, a circuit board 7, a cap 8 and a staple 9 providing a fastening structure. In other embodiments, the switch 6 is not a microswitch.

[0033] The housing 3 includes a cylindrical outer wall 10 extending from the outer edge of an annular top plate 11. A cylindrical inner wall 12 extends from an axial opening 13 formed in the top plate 11 to provide an annular magnet chamber within which an annular magnet 4 is secured. The depth of the inner wall 12 is significantly shallower than the depth of the outer wall, approximately one-quarter in this example, and the depth of the magnet 4 is approximately twice as deep as the depth of the inner wall. The magnet 4 may be secured to the magnet chamber by adhesive or by forming a retaining rib 14 on the outer wall 10 that presses the magnet against the housing during assembly (i.e., the retaining rib 14 extends radially inward from the outer wall 10 and abuts the underside of the magnet 4 to secure the position of the magnet 4). Additionally or alternatively, the magnet 4 may be secured within the magnet chamber by magnetic attraction to the housing 3. In embodiments including the retaining rib 14, the distance between the rib 14 and the top plate 11 is equal to the depth of the magnet 4.

[0034] Housing 3 can be formed from or include any suitable rigid material. Housing 3 can be formed from or include a metal, such as copper. Housing 3 can be formed from or include any suitable plastic. In some embodiments, housing 3 is formed from or includes a malleable rigid material. In some embodiments, housing 3 is formed from or includes a malleable rigid material that is ferromagnetic or paramagnetic (i.e., experiences a positive magnetic attraction to a permanent magnet).

[0035] The housing 3 may be waterproof. The female part 1 of the switch clasp may be waterproof to protect the internal circuitry from water.

[0036] The switch clasp may have an operating temperature of -15°C to 100°C. The switch clasp may be configured to withstand temperatures of -15°C to 100°C. The switch clasp may be configured to protect internal circuit components from temperature damage at temperatures of -15°C to 100°C.

[0037] The float 5 comprises a thin disk 5a, from which a cylindrical boss 15 extends axially, forming a sliding fit with the annulus of the magnet 4. The radius of the cylindrical boss 15 is substantially equal to the radius of the axial opening 13 so that the cylindrical boss 15 can slide freely within the opening 13. A through-hole 16 may be formed in the axis of the float 5. A monostable microswitch 6 is mounted below the float 5. The switch 6 has two switch states, on and off. As shown in FIG. 3 , the actuator pin 17 of the microswitch is biased by a spring 17a to press against the underside of the float 5, thereby pressing the float 5 against the magnet 4. The through-hole 16 may be configured to maintain magnetic flux lines passing therethrough. The microswitch 6 is mounted on a disk-shaped circuit board 7, providing electrical contacts 18. The switch 6 is soldered to the circuit board 7.

[0038] The electrical contacts 18 align with openings 19 formed in the cap 8, allowing connections to be made with conductors of an external circuit. The electrical contacts 18 are conductive locations on the circuit board 7 that align with the openings 19. The external conductors may be provided to provide a means for electrical conduction between the electrical contacts 18 and external circuit components. For example, the electrical contacts 18 may be configured to electrically connect the circuit board 7, along with the microswitch 6 mounted thereon, to an external circuit. The external circuit may include a power source such as a battery. The external circuit may include one or more output devices such as an LED, a light bulb, a buzzer, a speaker, a vibration means, a silent alarm, a location means, etc. The external circuit components may be configured to provide further electronic processing or communication with an external device such as a smartphone. The electrical contacts 18 are electrically connectable to an external circuit via conductive wires (e.g., copper wires) threaded through the openings 19. In other embodiments, instead of conductive wires, a ribbon cable or any other suitable means may be used to connect the circuit board 7 to the external circuit.

[0039] In other embodiments, such as the embodiment shown in Figure 7, the power supply and output device are integral with the female part 1 of the clasp, and in such embodiments, there may be no external circuitry. In such embodiments, openings 19 and electrical contacts 18 may be omitted. In other embodiments, only one of the power supply or output device is integral with the female part 1, and external circuitry is still required.

[0040] The cap 8 is a disk of plastically deformable material, such as metal or plastic, that is machined, for example by stamping, to form a pair of rims into protruding staples 9 to provide fastening structure for the female part 1. In some embodiments, the staples 9 are separate components that are connected to the cap 8. In such instances, the staples 9 may be connected to the cap 8 via adhesive, screws, or any other suitable means. The cap 8 is secured to the open bottom of the housing 3 with a deforming clip mechanism 20 that protrudes from the lower edge of the outer wall 10. During assembly, the circuit board 7 abuts against a first side of the cap 8, and the deforming clip mechanism 20 abuts against the periphery of the second side of the cap 8.

[0041] To disassemble the female part 1, the cap 8 is removed. To remove the cap 8 from the housing 3, the user applies force to the cap, which in turn applies force to the deformation clip mechanism 20. The user may apply force to the cap 8 via the staples 9. In some embodiments, the cap 8 includes a retainer (not shown) that allows the user to firmly grip the cap 8 in order to apply force to the cap 8.

[0042] As best seen in FIG. 3, the cap 8, circuit board 7, microswitch 6, float 5 and magnet 4 form an interference fit within the housing 3 such that each of the components is held in a fixed position relative to one another.

[0043] In other embodiments, such as those shown in FIGS. 8-16, the cap 8 may be replaced by a cover 26 .

[0044] The male part 2 is formed from a cylindrical protrusion 21 having dimensions that fit into the opening 13. The protrusion 21 is concentrically attached to a disk 22 made of a ferromagnetic or paramagnetic material, such as steel, that is attracted to the annular magnet 4. The disk 22 acts as a complementary attraction. In a variant, the disk 22 may be a permanent magnet to increase the force of attraction between the disk 22 and the magnet 4. A staple 23 is secured to the backside of the disk 22 by spot welding to provide a fastening structure for the second male part. In other embodiments, the staple 23 is secured to the backside of the disk 22 by adhesive or any other suitable means.

[0045] The shape and size of the disc 22 of the male part 2 is substantially the same as the shape and size of the top surface 11 of the housing 3 of the female part 1. However, this is not required.

[0046] 1-3, the protrusion 21 is shown concentrically mounted on the disk 22, but it is not necessary for the protrusion 21 to be central. In other embodiments, the protrusion 21 may be mounted anywhere on the disk 22. Similarly, the opening 13 in the female part 1 is not limited to being a central opening; it just needs to be configured to accommodate the protrusion 21.

[0047] In use, the female assembly 1 is secured to an article or portion of an article, such as the body of a handbag, by passing the rim of the staple 9 through the skin (also referred to as the "web") of the bag. The male part 2 is secured to another article or portion of the article, such as the closure flap of a bag, by passing the rim of the staple 23 through a corresponding skin of the flap. The male and female parts 2,1 can be used in place of a standard clasp. The male and female parts 2,1 can be secured to opposite sides of a bag, such as a handbag, to provide a fastening means for the bag. The male and female parts 2,1 can each be secured to the bag and the closure flap of the bag, or vice versa, to provide a fastening means for the bag.

[0048] In some embodiments, one or both of the staples 23,9 are replaced with alternative fastening structures. In some embodiments, adhesive may be used to fasten the male and / or female parts 2,1 to the relevant portions (e.g., skins, closure flaps) of an article (e.g., bag, garment, etc.). In some embodiments, the disk 22 may include a plurality of stitching holes configured to allow the male part 2 to be sewn to its respective portion. In some embodiments, the cap 8 may include a plurality of stitching holes configured to allow the female part 1 to be sewn to its respective portion.

[0049] When the male part 2 is brought close to the female part 1, the force generated by the magnet 4 attracts the disk 22, causing the protrusion 21 to be drawn into the opening 13 until the disk 22 contacts the top plate 11 of the housing 3. The depth of the protrusion 21 pushes the float 5 to overcome the depth of the magnet 4. The protrusion 21 therefore displaces the float 5 from the magnet 4 to the extent necessary to switch the state condition of the microswitch 6 (i.e., turn the switch on / off). Figures 4-6 show the male part 2 housed inside the female part 1 (i.e., the male part 2 and female part 1 are engaged).

[0050] The provision of float 5 ensures that the action of spring 17a provides a continuous compressive force that biases circuit board 7 and cap 8 against retaining clip 20 to hold each in place. Float 5 is not a required feature of the present invention and is omitted in other embodiments, such as the embodiment of Figure 7.

[0051] If the terminals 18 (also referred to as "electrical contacts") of the microswitch 6 are connected in a control circuit, a change in the state of the microswitch 6 can be used to turn a light on or off within the handbag or to sound an alarm indicating unauthorized opening of the clasp if the alarm is not deactivated first. The switch 6 can be used as part of any external circuit. The switch 6 can be used to switch an external circuit connected to it via the contacts 18. The external circuit can be housed in the same item as the clasp (e.g., the external circuit can be housed within or connected to the bag).

[0052] 1-6 show the male part 2 with a cylindrical protrusion 21 and the female part 1 with a circular opening 13, in other embodiments, the protrusion 21 and opening 13 can have any other shape, so long as the protrusion 21 is configured to fit within the opening 13. For example, the opening 13 can be square, rectangular, triangular, etc.

[0053] Although Figures 1 to 6 show the male and female parts 2,1 having a circular cross section (ie they are substantially cylindrical), in other embodiments they may have any other cross-sectional shape.

[0054] As briefly described above, Figures 4-6 correspond to Figures 1-3, but with male part 2 connected to female part 1. As shown in Figure 6, spring 17a is compressed via actuator pin 17 to change the switch state (i.e., on / off, open circuit or closed circuit) of microswitch 6. Actuator pin 17 is held in a compressed position via protrusion 21, which is then held in place by the magnetic force between magnet 4 and disk 22. The magnetic force between magnet 4 and disk 22 is strong enough to compress spring 17a by an amount sufficient to change the state of switch 6.

[0055] The switch 6 described above and shown in FIGS. 1-6 is a push button switch. The switch state of the switch 6 may be changed (i.e., turn the switch on / off) by compressing the actuator pin 17. In other embodiments, any other suitable type of switch 6 may be used. In some embodiments, such as the embodiment of FIG. 11, the switch 6 is a lever switch, and the protrusion 21 is configured to actuate the lever to change the switch state of the lever switch (i.e., turn the switch on or turn the switch off).

[0056] In other embodiments, the switch 6 may be configured to detect the presence of the magnet 4. In such embodiments, the switch 6 may be located on either the male part 2 or the female part 1, with the magnet located on the opposite side. In such embodiments, the switch 6 may be a Hall Effect sensor or a reed switch. Such embodiments are described later in this specification, for example, with reference to Figures 16 and 17.

[0057] As explained above, electrical contacts 18 allow switch 6 to be electrically connected to external circuitry, which may include one or more output devices. Connecting the male and female components 2,1, and therefore activating switch 6, may activate or deactivate one or more output devices.

[0058] 7 shows an exploded side view of the female part 1 of a switch clasp according to another embodiment. The male part (not shown) of this embodiment is substantially equivalent to the male part 2 of the embodiment of FIGS.

[0059] The circuit board 7, microswitch 6 and magnet 4 are identical to the corresponding components in the embodiment of Figures 1-6, but without the float. When assembled, the actuator pin 17 of the microswitch 6 extends into the opening in the magnet 4, and in use, the protrusion 21 of the male part 2 applies force directly to the actuator pin 17, rather than the float, to operate the switch 6. In other embodiments, the switch 6 may be any other suitable type of switch, such as a lever switch, as previously described.

[0060] The female part 1 comprises an output device 101 and a battery 103. The battery is a coin cell in this embodiment, but in other embodiments it can be any other type of battery or power source. In the embodiment of Figure 7, there are three output devices 101, but in other embodiments there may be one output device, two output devices, or any other number of output devices.

[0061] During assembly, the output device 101 is attached to and / or electrically connected to the circuit board 7 (e.g., the output device 101 can be soldered to the circuit board 7). The battery 103 is attached to and / or electrically connected to the circuit board 7. The battery 103 provides power to the circuit board 7 and other circuit components in the female part 1. In the embodiment shown in FIG. 7 , the cap 8 includes battery contacts 105. The battery contacts 105 are configured to hold / secure the battery 103 in place relative to the circuit board 7 during assembly such that when a user disassembles the female part 1 and removes the cap 8, the battery 103 is released and can be replaced. Alternatively, or additionally, the battery contacts 105 can provide an electrical connection between the battery 103 and the circuit board 7.

[0062] Unlike the embodiment of FIGS. 1-6, cap 8 does not have opening 19 because output device 101 and battery 103 are housed within housing 3 of female part 1. Because both battery 103 and output device 101 are contained within female part 1, the need to connect the clasp to any external circuit components is eliminated. For example, circuit board 7 can be used to provide a circuit with battery 103, output device 101, and switch 6 in a simple series circuit. In such an embodiment, activating switch 6 (via protrusion 21 of male part 2) turns output device 101 on and off. Output device 101 can be a light bulb, LED, audio device, etc. In other embodiments, cap 8 still has an opening, allowing female part 1 to be connected to external circuit components to provide additional functionality.

[0063] The outer wall 10 of the housing 3 includes a slot 104. The slot 104 prevents the outer wall 10 from blocking the output of the output device 101. For example, in embodiments where the output device 101 is an LED or a light bulb, the slot 104 allows light to pass away from the housing 10 to illuminate the area surrounding the female part 1 of the switch clasp. In embodiments where the output device 101 is a buzzer, speaker, or any other type of audio device, the slot 104 allows sound to pass through unimpeded. In other embodiments, the housing 3 may include multiple slots 104. In other embodiments, the housing 3 includes one or more alternatively shaped passageways instead of the slot 104. For example, the housing 3 may include one or more holes of any shape and size.

[0064] In other embodiments, the female part 1 may include the battery 103 without also including the output device 101, or vice versa. In such embodiments, the cap 8 includes one or more openings 19 that allow connection to external circuitry.

[0065] Another embodiment of the invention is shown in Figures 8-10, which differs from the embodiment of Figures 1-6 in that the float 5 is omitted, as are the staples 9. The male part 2 of the switch clasp is the same as in the embodiment of Figures 1-6.

[0066] Instead of staples 9, the female part 1 is adapted to be secured to the web (also referred to herein as "skin") in use by an annular flange 24 that extends around the periphery of the housing 3. The flange 24 cooperates with a flange 25 formed on an elastically deformable, monostable cover 26 to clamp the web therebetween, thereby providing a fastening structure. The cover 26 is dome-shaped. The cover 26 in the embodiment of Figures 8-10 is used in place of a cap.

[0067] The cover 26 includes resiliently deformable clasp teeth 100 that are used to clamp the flanges 24, 25 together. The housing 3 includes internal ribs 102 configured to engage the clamping teeth 100 to secure the position of the cover 26 relative to the housing 3. During assembly, the clasp teeth 100 engage with the internal ribs 102 formed on the housing 3 to securely secure the position of the flanges 24, 25 relative to one another. The internal ribs 102 are radial protrusions that extend inward from the outer wall 10 of the housing 3. The clasp teeth 100 are configured to enter the housing 3 and engage with the internal ribs 102. Each clasp tooth 100 includes a hook portion that "engages" the internal ribs 102 when the hook portion is positioned between adjacent internal ribs 102.

[0068] 11, there are multiple internal ribs 102 that allow the clasp teeth 100 to be inserted at various distances into the housing 3. The ability to secure the clasp teeth 100 to any of the multiple internal ribs 102 on the housing 3 allows the flanges 24, 25 to be secured at various distances relative to one another, thereby allowing the flanges 24, 25 to clamp various materials of different thicknesses.

[0069] In other embodiments, the clasp teeth 100 and internal ribs 102 can be replaced with corresponding threaded portions on the housing 3 and cover 26 .

[0070] The dome-shaped cover 26 can be temporarily deformed, such as by finger pressure, to activate the second microswitch 27. Alternatively, the dome 26 can have a hole through which the actuator of the switch 27 extends, allowing the user to activate the switch 27. The second microswitch 27 is located on the opposite side of the circuit board 7 from the first microswitch 6 and is positioned substantially at the central axis of the switch clasp. The second microswitch 27 therefore provides additional logic to the switch clasp; for example, an alarm that would otherwise be activated by releasing the clasp can be deactivated by pressing a button formed by the cover. In other embodiments, the second microswitch 27 is used to deactivate an LED or other output device or external circuit component. In the embodiment of FIGS. 8-10, the second microswitch 27 is a pushbutton switch. In other embodiments, the second microswitch 27 is a lever-activated switch. In some embodiments, the female part 1 includes the cover 26 but does not include the second microswitch.

[0071] In some embodiments, as described with respect to other embodiments, circuit board 7 is connected to external circuit components via suitable conductive means (e.g., conductive wire, conductive ribbon). In some examples, conductive means passes between flanges 24, 25 to provide electrical connection between circuit board 7 and external circuit components / devices. In other embodiments, cover 26 includes one or more holes through which conductors can extend.

[0072] Figure 11 shows an embodiment of a switch clasp that is substantially similar to the embodiment of Figures 8 to 10. Figure 11 shows an exploded side view of the female part 1 of the switch clasp. The male part 2 (not shown) of the switch clasp of this embodiment is the same as that in the first embodiment of Figures 1 to 6.

[0073] As shown in the embodiment of Figures 8 to 10, the switch clasp includes a dome-shaped cover 26 together with flanges 24, 25. The switch clasp of Figure 11 does not include a second microswitch.

[0074] Figure 11 shows resiliently deformable clasp teeth 100 formed on and extending from domed cover 26. Upon assembly, clasp teeth 100 engage internal ribs 102 formed within housing 3 to securely secure flanges 24, 25 in position relative to one another, as in the embodiment of Figures 8-10.

[0075] In the embodiment of Figure 11, switch 6 is a lever switch rather than a push button switch. When male part 2 is inserted into female part 1, the magnetic force between magnet 4 and disc 22 causes protrusion 21 to actuate the lever of switch 6, changing the switch state.

[0076] In some embodiments, one or more output devices 101 are mounted on and / or electrically connected to the circuit board 7. The one or more output devices 101 may include one or more of a light, buzzer, alarm, speaker, etc. In the example of FIG. 11, the output device 101 is preferred and the second microswitch 27 is omitted. However, in other embodiments, the switch clasp may include the second microswitch 27 as well as one or more output devices 101. In embodiments including the output device 101 within the female part 1, the circuit board 7 may be connected to external circuitry to provide power (e.g., the circuit board 7 may be connected to a battery).

[0077] Figures 12 and 13 show side cross-sectional views of a clasp switch according to another embodiment. The embodiment of Figures 12 and 13 is generally similar to the embodiment of Figures 8-10, except that the second microswitch 27 is eccentrically mounted to the circuit board 7 near the periphery of the cover dome 26. The inner surface of the cover dome 26 is formed with a shoulder 28 that creates a space between the circuit board 7 and the cover 26 just large enough to accommodate the microswitch 27 in a relaxed state when the cover 26 is in a stable state. With this configuration, only minimal movement of the cover 26 is required to depress and activate the second microswitch 27. This reduces the required deformation of the cover 26, thereby increasing the durability of the cover 26.

[0078] The embodiment of Figures 12 and 13 also differs from the embodiment of Figures 8-10 in that the coin cell battery 103 is connected to the circuit board 7 via battery contacts 105. This is not a required feature, and instead an external power source may be connected to the circuit components within the female part 1.

[0079] FIG. 14 shows a side cross-sectional view of a switch clasp according to another embodiment.

[0080] The female part 1 of this embodiment is generally similar to the female part 1 in the embodiment of Figures 8-10 and 12-13, except that the microswitch 6 is of a lever-actuated type instead of a push-button type. Instead of using clip teeth 100, the cover 26 is provided with a threaded sleeve 29 that supports the circuit board 7. The threaded sleeve 29 facilitates fastening of the cover 26 to a corresponding threaded outer wall 30 of the housing 3 through which the flange 24 extends. The flange 25 clamps the web against the flange 24 when the cover 26 is screwed onto the housing 3 through a correspondingly sized hole in the web.

[0081] Figure 15 shows an exploded perspective view of a switch clasp according to another embodiment. The embodiment of Figure 15 is substantially similar to the embodiment of Figure 14, except that the sleeve 29 is not threaded. Instead, the sleeve includes clasp teeth 100. The housing 3 includes a plurality of annular ribs 102 extending inwardly from the outer wall 10. The clasp teeth 100 are configured to engage the annular ribs 102 to clamp the flanges 24, 25 together.

[0082] 14 and 15, the female part 1 comprises a coin cell battery 103 and an output device 101. In such an embodiment, there is no need to connect the circuit board 7 or the switch 6 to external circuit components.

[0083] 16 shows an alternative switch clasp according to another embodiment of the present invention. The switch clasp comprises a male part 2 and a female part 1.

[0084] The female part 1 comprises a housing 3 and a cover 26. The housing 3 comprises a flange 24 and the cover 26 comprises a flange 25. As described with respect to other embodiments, the flanges 24 and 25 sandwich a material / web therebetween. The female part 1 comprises a circuit board 7 housed between the cover 26 and the housing 3.

[0085] The female part 1 includes a switch 6 adjacent to an opening 13 formed in the housing 3. The switch 6 is a reed switch or a magnetic sensor such as a Hall effect sensor.

[0086] The male part 2 carries an annular magnet 4 adjacent to a protrusion 21. In use, the protrusion 21 of the male part 2 enters the opening 13 of the female part 1 and the magnetic sensor 6 detects the presence of the magnet 4 and generates a signal to, for example, activate one or more output devices or provide a signal to external circuitry. The housing 3 includes or is made of a magnetic material so that when the housing 3 is adjacent to the magnet 4, it experiences a positive attractive force on the annular magnet 4.

[0087] Figure 17 shows an alternative switch clasp according to another embodiment of the present invention. The switch clasp comprises a male part 2 and a female part 1. The switch clasp of this embodiment differs from the previously described embodiments mainly in that the male part 2 comprises a switch 6. In this embodiment, the switch 6 is a magnetic sensor such as a reed switch or a Hall effect sensor.

[0088] The female part 1 includes an annular magnet 4 surrounding a central opening 13. The male part 2 includes a housing 47 formed from or including a paramagnetic and / or ferromagnetic material such that it is subject to an attractive force when brought into proximity with the annular magnet 4 of the female part 1. The housing 47 of the male part 2 defines a protrusion 21 configured to fit within the opening 13 of the female part 1. The male part 2 includes a circuit board 7 secured in place by the housing 47. A switch 6 is mounted to the center of the circuit board 7. The switch 6 is mounted to the circuit board 7 such that the switch 6 extends into the protrusion 21.

[0089] Male part 2 includes cover 26. Cover 26 includes a male-threaded sleeve that engages with a female-threaded sleeve portion of housing 47. A user can rotate and remove cover 26 to access circuit board 7 and any components mounted thereon. Cover 26 includes flange 25, and 47 includes flange 24. Flanges 24, 25 are configured to clamp a material or web therebetween, as in the previous embodiments.

[0090] As the protrusion 21 of the male part 2 enters the opening 13 of the female part 1, the magnetic sensor 6 detects the presence of the annular magnet 4 and generates a signal to, for example, activate one or more output devices or external circuit components. The housing 47 is formed from or includes a magnetic material so as to be subjected to a magnetic attractive force when in proximity to the magnet 4. The magnetic attractive force between the housing 47 and the magnet 4 results in coupling between the male part 2 and the female part 1.

[0091] 18 shows a cross-sectional side view of a switch clasp according to another embodiment. The embodiment of FIG. 18 comprises a female part 1 and a male part 2.

[0092] The female part 1 is formed from a generally annular housing 3, in which an inner wall 12 extends gradually downward from the edge of the housing 3 to form an opening 13. An elastically deformable spring clip 31 is threaded through the opening formed in the inner wall 12. A side wall 30 of the housing 3 extends downward from the edge of the housing to form a chamber in which the microswitch 6 is housed, with the actuator of the microswitch 6 positioned on the axis of the opening 13. A housing base 32 extends from the side wall 30, whereby the microswitch 6 is fixed between the base 32 and the lower edge of the wall (inner wall) 12 of the opening.

[0093] In the embodiment of Figure 18, the switch 6 is a push button switch. In other embodiments, a lever switch can be used.

[0094] The circuit board 7 is disposed in the chamber between the microswitch 6 and the base 32. The circuit board 7 is in electrical communication with the microswitch 6. In some embodiments, the switch 6 is soldered to the circuit board 7. Although not shown in FIG. 18 , the female part 1 includes openings that allow for the connection of conductors to provide electrical communication between the circuit board 7 and external circuitry. In some embodiments, the openings are formed in the base 32. In other embodiments, the openings are formed in the sidewall 30. While conductors are not shown in FIG. 18 , they are substantially similar to those shown in the embodiments of FIGS. 19 and 20 , which are described in more detail below. As described with respect to other embodiments, conductors can be used to connect the switch 6 to external circuitry. The external circuitry may include a power source and / or one or more output devices.

[0095] The male part 2 comprises a disk 22 having a rim 33 formed by folding back the circular edge of the disk 22. The centre of the disk 22 is plastically deformed into a pin 34 having an outer shape and diameter similar to the inner diameter of the opening 13 in the female part 1. The pin 34 is formed with a reduced diameter necked area so that when the pin is pressed into the opening 13, the necked area cooperates with a spring clip 31 to capture the pin 34 and press the end of the pin 34 against the actuator (or lever) of the microswitch 6. The spring clip 31 holds the male part 2 in the female part 1. A user can apply force to the male part 2 to elastically deform the clip 31, allowing the male part 2 to be released from the female part 1.

[0096] Fastening structures are provided by openings through each of the female and male parts 1 and 2, which, in use, allow thread to be passed through to secure the parts to their respective opposing webs. The fastening structures are not shown in Figure 18, but they are equivalent to the fastening structures 106 shown in the embodiment of Figure 20, described later in this specification.

[0097] The microswitch 6 is preferably connected to an external circuit component (not shown) via a circuit board 7. When the male part 2 is pushed into the female part 1 to depress an actuator (or lever) of the microswitch 6, one or more output devices of the external circuit component may be activated. For example, the external circuit component may include a light as an output device, and the male and female parts 2, 1 of the switch clasp may be secured to opposite sides or parts of a bag or opposite sides of a garment.

[0098] Figure 19 shows a side cross-sectional view of a switch clasp according to another embodiment, and Figure 20 shows an exploded perspective view of the embodiment of Figure 19.

[0099] The embodiment shown in Figures 19 and 20 is generally similar to the embodiment shown in Figure 18, except that the axially mounted microswitch 6 has been removed and instead a Hall effect sensor 35 has been mounted on the top side of the circuit board 7. The Hall effect sensor is soldered to the circuit board 7. A round permanent magnet 36 is fixed to the edge 33, allowing the Hall effect sensor 35 to sense movement of the male part 2 mating with the female part 1. An output is provided from the circuit board 7 via a conductor 37. In an alternative embodiment, the Hall effect sensor 35 could be replaced by a reed switch. The conductor 37 provides an electrical connection between the Hall effect sensor / reed switch and external circuitry, which may include an output device and / or power source as described with respect to the other embodiments.

[0100] As shown in Figure 20, the circuit board 7 and the male and female components 2,1 include fastening structures 106 and the male and female components 2,1. It is optional for the circuit board 7 to include fastening structures. In the embodiment of Figure 18, the circuit board 7 does not include fastening structures 106.

[0101] For clarity, the components in Fig. 20 are not shown in the same order as they are assembled in Fig. 19. Although the circuit board 7 and Hall effect sensor 35 are shown on the outside of the female part 1 in Fig. 20, this is solely for clarity. As shown in Fig. 19, when assembled, the circuit board 7 and Hall effect sensor 35 are inside the female part.

[0102] 19 and 20, the circuit board 7 is not positioned relative to the base 32 during assembly. Instead, the circuit board 7 is positioned near the top plate (in the perspective of the figures) of the female component 1. The circuit board 7 has a central opening configured to allow the interior wall 12 of the female component 1 to pass through. The side walls 30 provide surfaces that support and maintain the position of the circuit board 7. These features ensure that the circuit board 7 and the Hall effect sensor 35 are in close proximity to the top plate of the female component 1, which in turn can make it easier for the Hall effect sensor 35 to detect the magnet 36 when the male component 1 enters the female component 2.

[0103] 21 to 23 and 24(a) and (b) show another embodiment of the switch clasp, in which the sensor assembly is located in the male part 2 instead of the female part 1.

[0104] The male part 2 comprises a generally rectangular housing 3 which incorporates a circuit board 7 containing a potentiometer 39. The potentiometer 39 is attached to the circuit board 7. A coin cell 38 is attached to the circuit board 7. The potentiometer 39 is coupled to a rotor 40 via a shaft 41. A back surface 107 of the housing 3 can be secured to a web by staples, stitching or any other conventional means. The web is secured between the back surface 107 and the remainder of the housing 3.

[0105] The female part 1 has a generally rectangular ring with a central through opening 108 that can accommodate the housing 3 of the male part 2. The length, width, and depth of the opening 108 are substantially equal to the length, width, and opening of the housing 3 of the male part 2. Although the female part 1 is described as having a "rectangular" ring, in other embodiments, the female part 1 can have any shape, so long as the central opening 108 is configured to accommodate the housing 3 of the male part 2. When the female part 1 is attached to an article (e.g., a closure flap, the side of a bag, or other article), a hole is punched in the article to align with the opening 108. The female part 1 is then secured to the article using staples, stitches, or any other conventional means.

[0106] The female part 1 also includes a retaining portion 109. In other embodiments, the female part 1 does not include a retaining portion. The retaining portion 109 is a recess formed along the inner edge of the top surface 112 of the ring. The retaining portion 109 is centrally located along the length of the ring. The retaining portion 109 extends downward from the top surface 112 of the ring. The retaining portion 109 has a depth that is less than the height of the ring; in the embodiment shown in FIG. 16, the retaining portion 109 has a depth that is approximately equal to one-third the height of the ring. The width of the retaining portion is substantially equal to the width of the rotor 40.

[0107] In use, the switch clasp is locked (i.e., the male and female parts 2, 1 are locked) by placing the housing 3 in the ring (i.e., placing the housing 3 in the opening 108 so that the entire depth of the housing 3 is within the opening 108) and rotating the rotor 40 from the inserted condition shown in Figures 21 and 23 to the locked condition shown in Figure 22. In the inserted condition, the male part 2 is configured so that the rotor 40 is aligned parallel to the housing 3 (i.e., the length of the rotor is parallel to the length of the housing 3). In the locked condition, the male part 2 is configured so that the rotor 40 is aligned perpendicular to the housing 3 (i.e., the length of the rotor 40 is perpendicular to the length of the housing 3). When the male part 2 is placed in the opening 108 and the rotor 40 is rotated to the locked condition, the underside of the rotor 40 rests against the top surface 112 of the ring, attracting the parts together. When the user releases the male and female parts 2,1 after securing the clasp, the male part 2 partially extends from the female part 1 (i.e., a portion of the housing 3 extends from the opening 108, but most of the housing 3 remains within the opening 108) so that the underside of the rotor 40 abuts against the top surface 110 of the retaining portion 109. The sidewalls 111 of the retaining portion 109 abut the sides of the rotor 40, preventing accidental rotation of the rotor 40. To release the connection between the male and female parts 2,1, the user inserts the housing 3 completely into the opening 108, pushing the rotor 40 out of the retaining portion 109 and freeing it to rotate, and then the user rotates the rotor 40 back to the inserted condition.

[0108] Rotation of the rotor 40 is sensed by a change in the resistance of the potentiometer 39, and the engaged or disengaged condition is determined by the current or voltage across the potentiometer, whose correlation to the condition is output on the output conductor 37. The potentiometer acts as a switch controlling one or more output devices. The output conductor 37 may connect circuitry in the male part 2 to external circuitry. As in other embodiments, the external circuitry may include one or more output devices and / or a power source. In one example, a switch clasp is used to activate one or more output devices, for example, to illuminate the interior of a bag / purse. In such an example, the male and female parts 2,1 are connected to opposite sides of the bag. When the rotor 40 is in the inserted condition, the potentiometer may turn on the light. When the rotor 40 is rotated 90° to the locked condition and the male and female parts 2,1 are securely connected together (as shown in FIG. 16), the potentiometer may turn off the light.

[0109] In other embodiments, a rotary switch may be used instead of the potentiometer.

[0110] In some embodiments, the male part 2 comprises a battery 38 attached to the circuit board 7. In some embodiments, the male part 2 comprises an output device 101 in electrical communication with the circuit board 7. In some embodiments, the conductor 37 may be omitted because the male part 2 comprises a self-contained circuit.

[0111] Figures 25(a) and (b) show exploded side and perspective views of a switch clasp according to another embodiment. Figure 26 shows a side cross-sectional view of the same embodiment. The embodiment is most similar to the embodiment of Figures 21-23 and 24(a) and (b), however, engagement or disengagement of parts 1 and 2 is sensed by a Hall Effect sensor 35 mounted on circuit board 7 of male part 2, which senses the presence or absence of a magnet 36 mounted on female part 1. In other embodiments, Hall Effect sensor 35 may be replaced by a reed switch.

[0112] The connection and locking between the male part 2 and the female part 1 is the same as in the embodiment of Figures 21 to 24. The male part 2 comprises a housing 3 and a rotor 40, and the female part 1 comprises a central opening 108 adapted to receive the housing 3 as described above.

[0113] In the embodiments of Figures 25(a) and (b) and 26, the female part 1 comprises a magnet 36. In the embodiment shown, there are two magnets 36 located at opposite ends of the ring. In other embodiments, the female part 1 may comprise a single magnet or any number of magnets.

[0114] Instead of a potentiometer, the male component 2 includes a Hall Effect sensor 35 or reed switch. In use, a user places the housing 3 within the opening 108, causing the Hall Effect sensor 35 to detect the presence of the magnet 36. The Hall Effect sensor 35 sends / generates an electrical signal in response to detecting the magnet 36. In one example, the Hall Effect sensor 35 acts as a switch. In such an embodiment, the Hall Effect sensor 35 may act as an open circuit when the male and female components 2,1 are connected and as a closed circuit when the male and female components 2,1 are separated, or vice versa. This can be used to illuminate an area with an output device 110, such as a light bulb or LED, when the male and female components 2,1 are separated. Additionally or alternatively, the Hall Effect sensor 35 may generate and / or transmit a signal to an external circuit for further processing.

[0115] Figures 27(a) and (b) and Figure 28 show an alternative embodiment of a switch clasp according to an embodiment of the present invention. This embodiment is substantially similar to the switch clasps of Figures 21-24 and 25-26. Figure 27(b) shows a cross section of the male part 2 of the embodiment of Figure 27(a), allowing the internal components to be seen.

[0116] The male part 2 comprises a rotor 40 which, together with the opening 108 in the female part 1, provides a locking mechanism as described in the previous embodiment. The rotor 40 is connected to a rotating part 45 which rotates together with the rotor 40. The male part 2 comprises a spring 47 which is compressed between the top side of the housing 3 and the rotating part 45 such that the spring 47 exerts a force on the rotating part 45 to maintain abutment between the rotating part 45 and the printed circuit board 7.

[0117] 28, the rotating portion 45 includes a conductive portion 46. The conductive portion 46 extends across the diameter of the rotating portion 45. In use, as the rotor 40 is rotated between the inserted condition and the locked condition, the conductive portion 46 rotates relative to the PCB 7. Electrical contacts or electrodes are disposed on the PCB 7. The positions of the electrical contacts / electrodes are configured such that a circuit can be "open" or "closed" depending on the orientation of the conductive portion 46.

[0118] For example, when rotor 40 is in the inserted condition, conductive portion 46 may establish an electrical connection to complete a circuit (i.e., electrical contacts may touch conductive portion 46) and provide power to one or more output devices. Rotating rotor 40 to a locked configuration may break the circuit and remove power to one or more output devices. Thus, rotor 40 acts simultaneously as a locking mechanism and a switch.

[0119] Figure 29 shows a side cross-sectional view of a switch latch / clasp according to another embodiment of the present invention. Figure 30 shows a perspective view of the switch latch of Figure 29, but with the male and female parts 2, 1 disengaged. The embodiment shown in Figures 29 and 30 shows a latch in the form of a wedge where the male part 2 is forced into the female part 1, deforming the wedge surface 41 upon engagement with the hoop 42. The stress applied by the deformation attracts the male part 2 to the female part 1.

[0120] The male part 2 incorporates a magnet 36. The male part 2 comprises a base within which the magnet is housed. The male part 2 comprises a wedge portion extending from the base. The wedge portion comprises an elastically deformable wedge surface 41. The wedge surface 41 is sloped such that the height of the wedge portion decreases as it extends away from the base.

[0121] The female part 1 has a base that houses a circuit board 7. The circuit board 7 supports a coin cell 38 and a Hall effect sensor 35 such that the circuit electronics on the circuit board 7 are responsive to the proximity of the male part 2 in an engaged condition, or its absence in a disengaged condition. The female part 1 includes a hoop 42 extending from the base.

[0122] In use, the male part 2 is urged by the user towards the female part 1, forcing the wedge portion into the hoop 42. The wedge surface 41 deforms as it contacts the hoop 42, allowing the wedge portion to pass further through the hoop 42. The abutment of the hoop 42 with the deformed wedge surface 41 provides friction that prevents the male part 2 from sliding off the female part 1 without an external force applied by the user.

[0123] 29 and 30, the female part 1 also houses an output device 101. In the embodiment shown, there are three output devices 101, but in other embodiments there may be one output device 101 or any number of output devices 101. As with the other embodiments, the output device may be an LED, a light bulb, a buzzer, etc. The output device is mounted on the circuit board 7 opposite the coin cell 38 and Hall effect sensor 35.

[0124] When the male part 2 is secured in the female part 1 (via the hoop 42), the magnet 36 is sufficiently close to the Hall effect sensor 35 to enable the Hall effect sensor 35 to transmit / generate a signal. As in other embodiments, the Hall effect sensor 35 can act as a switch, for example, to control one or more output devices 101. In some embodiments, the Hall effect sensor 35 can be replaced with any other type of switch, such as a reed switch, that is capable of detecting the presence of the magnet 36.

[0125] In some embodiments, the coin cell 38 and / or the output device 101 are omitted from the female part 1. In such embodiments, the coin cell and / or the output device may form part of the external circuitry. In such embodiments, the circuit board 7 and switch 6 are connected to the external circuitry via conductors 37 in other embodiments described herein.

[0126] Figures 31 and 32 show side cross-sectional views of a switch latch / clasp according to another embodiment. The switch clasp of Figures 31 and 32 is substantially similar to the switch clasp of Figures 29 and 30, but it includes a switch 6 instead of a Hall effect sensor. The embodiment shown in Figure 31 has a hollow male part 2 providing a chamber 43 in which a microswitch 6 with a lever actuator is mounted on a circuit board 7.

[0127] In the disengaged condition (shown in FIG. 31 ), the microswitch 6 is pressed against the inner chamber surface below the wedge surface 41 (i.e., the lever of the switch 6 is in contact with the wedge surface 41). When the male part 2 is pressed into the female part 1, as shown in FIG. 32 , the hoop 42 deforms the wedge surface 41, displacing the tip of the microswitch lever. The circuit board 7 is responsive to the microswitch 6 to indicate the engaged and disengaged conditions. Displacing the lever of the microswitch 6 changes the switch condition. As with other embodiments described herein, the switch 6 can be used to turn one or more output devices on and off. As with other embodiments, the output devices may be integral to the male or female parts 2, 1, or may be part of an external circuit.

[0128] Figure 33 shows a side view of a switch clasp according to another embodiment of the present invention. The switch clasp comprises a male part 2 and a female part 1. The circuit components in the male and female parts 2, 1 can be equivalent to the circuit components in the switch clasp of Figures 29-30 or 31-32.

[0129] The wedge surface 41 of the male part 2 includes a lip 44. As the male part 2 is pressed into the female part 1, the hoop 42 deforms the wedge surface 41, allowing the male part 2 to extend into the female part 1 and the lip 44 to pass through the hoop 42. Once the lip 44 has passed through the hoop 42, the wedge surface 41 elastically returns to its original shape (i.e., the deformation is reversed). The lip 44 forms a surface that abuts against the side of the hoop 42 to prevent the male part 2 from disengaging from the female part 1.

[0130] Figures 34(a-c) show a zip clasp according to another embodiment of the present invention. These figures show the underside of the zip as it moves from a closed configuration in Figure 34(a), through an intermediate configuration in Figure 34(b), to an open configuration in Figure 34(c). The zip includes a pull tab 112 configured to connect two sets of teeth 113, 114, as in a conventional zip. The two sets of teeth 113, 114 can be attached (e.g., by stitching) to the fabric 116 of an article such as a bag, as in a conventional zip.

[0131] The conductive tracks 111 are positioned adjacent to and extend parallel to the pairs of teeth 113, 114. The conductive tracks 111 are formed from or include a flexible conductive material. In some embodiments, the conductive tracks 111 are formed from or include conductive ink, conductive thread, or any other conductive flexible material. In some embodiments, the conductive tracks 111 adjacent to a first pair of teeth 113 are separated from the conductive tracks 111 adjacent to a second pair of teeth 114, thereby forming two separate circuits. In some embodiments, the conductive tracks 111 form a single set of conductive tracks (i.e., the conductive tracks 111 adjacent to each pair of teeth 113, 114 are connected and coupled to form a continuous conductive track).

[0132] The Hall effect sensor 35 is connected to conductive tracks 111. Conductive tracks 111 are also connected to external circuit components (not shown) including one or more output devices and a power source such as a battery.

[0133] The pull tab 112 includes or is a magnet (i.e., the pull tab 112 is made of or includes a magnetic material). When the zip is closed (or opened), the pull tab 112 passes in proximity to a Hall Effect sensor 35, which generates an output signal. The output signal is used to control one or more output devices, such that the zip is configured to act as a switch. For example, the zip may be used to turn on a light when the zip is opened and turn off the light when the zip is closed.

[0134] In the embodiment of Figure 34, there are two Hall Effect sensors 35. In such an embodiment, one Hall Effect sensor 35 may be used to detect when the zip is in the closed configuration and the other Hall Effect sensor 35 may be used to detect when the zip is in the open configuration. In other embodiments, the zip clasp may include one Hall Effect sensor or any number of Hall Effect sensors. In some embodiments, one or more of the Hall Effect sensors 35 may be replaced by any component / circuitry suitable for detecting the presence of a magnet, such as a reed switch.

[0135] Figures 35(a-c) show a zip clasp according to another embodiment of the present invention. The zip clasp in the embodiment of Figure 35 is substantially similar to the zip clasp in the embodiment of Figure 34. Figures 35(a)-(c) show the underside of the zip as it moves from a closed configuration in Figure 35(a), through an intermediate configuration in Figure 35(b), to an open configuration in Figure 35(c). The zip includes a pull tab 112 configured to connect two sets of teeth 113, 114, as in a conventional zip.

[0136] The two sets of teeth 113, 114 can be connected to an article such as a bag in the same manner as a conventional zipper. A conductive track 111 is positioned adjacent to the sets of teeth 113, 114 and extends parallel to the sets of teeth 113, 114. The conductive track 111 is formed from or includes a flexible conductive material. The two sets of teeth 113, 114 are also formed from or include a conductive material. Alternatively, the majority of the teeth can be formed from or include a non-conductive material, with only the teeth described below with respect to the operation of the switch being formed from or include a conductive material.

[0137] The conductive track 111 is divided into two sections 111-1 and 111-2. The sections 111-1 and 111-2 of the conductive track 111 are connected to a pair of adjacent teeth 113-1 and 113-2 of the first set of teeth 113. The first section 111-1 of the conductive track 111 is connected to tooth 113-1. The second section 111-2 of the conductive track 111 is connected to tooth 113-2. As shown in FIG. 35(c), when the zip is in the open configuration, the teeth 113-1 and 113-2 are not in electrical contact with each other. The conductive track 111 forms an open circuit when the zip is in the open configuration.

[0138] When the zip pull tab 112 connects the two sets of teeth 113, 114, tooth 114-1 is positioned between teeth 113-1 and 113-2. Tooth 114-1 is made of or includes a conductive material, thus providing an electrical connection between teeth 113-1 and 113-2. Electrically connecting teeth 113-1 and 113-2 electrically connects the first and second sections 111-1, 111-2 of the conductive track 111. The connection between the two conductive track sections 111-1, 111-2 can be used to activate or deactivate an output device, allowing the zip to act as a switch.

[0139] In some embodiments, the conductive track 111 forms part of a circuit that activates an output device (e.g., lights up a light bulb / LED) or generates a signal for further signal processing by external circuit components. In such embodiments, closing the zip (and thus electrically connecting the two conductive track sections 111-1, 111-2) completes the circuit and provides power to the output device. In contrast, opening the zip to break the connection between conductive track sections 111-1, 111-2 removes power from the output device. In other embodiments, the reverse may be true: breaking the electrical connection between tines 113-1 and 113-2 (by opening the zip) may activate the output device (e.g., lights up a light bulb / LED).

[0140] In some embodiments, conductive track 111 is divided into more than two sections. In such embodiments, each section is connected to a conductive zip tooth, thereby forming a switch similar to teeth 113-1, 113-2, and 114-1 described above. The use of additional switches in such embodiments can be used to control additional output devices.

[0141] In the embodiment of Figures 34 or 35, the conductive track 111 can be protected by the fabric 116 to which the pair of teeth 113, 114 are connected. As shown in Figures 36(a) and 36(b), the fabric 116 is folded and the fold connects to the teeth 113, 114. The conductive track 111 can be placed on the surface of the folded fabric 116 inside the fold, as shown in Figure 36(a). Figure 36(a) also shows the connection 115 between one of the teeth 113 and the conductive track 111. Folding the fabric 116 before connecting to the teeth 113, 114 can help protect components such as the conductive track from the zipper pull tab.

[0142] In some embodiments, output devices and / or connections to external circuitry may be placed between the folded sides of the fabric 116. The fabric 116 may include one or more holes through which an output device can provide an output. The folded fabric 116 may also cover and protect the PCB and / or any other components.
