The release mechanism may be operated using two different movements and/or two different hands. The zip restraint may be biased towards either position, while a holding structure that holds it in the active position may also be included. A locking mechanism (120, fig.6), a sound and/or a light output, and connectivity to a processor, speaker, display, power supply and/or microphone may be provided. The zip restraint and/or zip pull-tab 16 may comprise a cover. Applications may include baggage, luggage, clothing and/or camping.

Description

Zip restraint

Field of the invention

The present invention relates to a zip restraint as well as an object comprising the zip restraint and a method of operating the zip restraint.

Backoround to the Disclosure

Zips are a convenient way to implement closable pockets on bags and clothing. However, while they are convenient, zips are insecure and can generally be opened with relative ease, either intentionally or unintentionally. For bags, pockets and other items with zips this can result in problems such as theft and pick-pocketing as well as the accidental exposure of items that may be harmful, dangerous, or embarrassing.

Solutions to this problem have previously been proposed. Notably, for zip arrangements that use two pull-tabs, locks are available that attach to the pull-tabs and secure the pull-tabs together. With such arrangements, the pull-tabs cannot be separated and so an associated pocket cannot be accessed.

However, such an arrangement is not user friendly, not least because it substantially increases the time needed for the rightful owner of a bag to access the bag. Therefore, an improved solution is desired.

Description of the preferred embodiments

Referring to Figure 1, there is shown an image of a zip (or zipper). The zip comprises two rows of interleaving teeth 12 and a slider 14 that is attached to the rows of teeth. The slider can be moved in a first direction (up with respect to Figure 1) to bring the separated teeth together and 'zip', or close, the zip or in a second direction (down with respect to Figure 1) to separate the connected teeth and 'unzip', or open, the zip.

To help a user of the zip to move the slider 14, zips typically comprise a pull-tab 16 that is connected to the slider.

Typically, zips comprise retaining boxes at one or more of the ends of the zip to ensure that the slider 14 cannot detach from the rows of teeth 12. Equally, only one of the rows of teeth may be associated with a retaining box so that the slider can be detached from the other row of teeth.

Zips may comprise a single slider or may comprise a plurality of sliders; where a plurality of sliders are used, a first slider is typically arranged to open a zip when it is moved in a first direction and a second slider is typically arranged to close the zip when moved in this first direction. Therefore, the sliders must be separated to access a cavity secured by the zip. Different arrangements are used for different purposes: often (but not always) items of clothing use zips with a single slider; and often (but not always) bags use zips with two sliders.

Zips are a convenient way of securing cavities (e.g. pockets). To secure a cavity, a row of teeth is attached to either side of an opening of the cavity (e.g. using tape). The slider is attached to a first end of each row of teeth and the slider can then be moved along the rows of teeth to connect the teeth and to thereby close the zip and secure the cavity. To access the cavity, the slider is moved in the opposite direction so that the rows of teeth are separated, the zip is opened, and the cavity is accessible.

Zips enable quick and easy access to cavities, while allowing users to secure a cavity to prevent items from falling out of the cavity.

However, zips can be operated easily and quietly by pickpockets. So while zips offer some (albeit imperfect) protection against accidental removal of objects from a cavity, they offer little protection against intentional malicious removal of objects. Furthermore, zips are vulnerable to being inadvertently opened if the slider is knocked against another object. Yet further, zips may be opened by young children thereby exposing embarrassing/harmful items or by parties wishing to encroach on a person's privacy (e.g. to access a personal diary or a phone).

Therefore, users often wish to lock zips to prevent them from being opened. A conventional method of locking a zip with two sliders involves placing a separate lock (e.g. a padlock) through the eyelets of the pull tabs of each slider. With such a method a pickpocket is able to move both sliders along the rows of teeth but is not able to separate the sliders to gain access to the cavity.

While this can be an effective method of locking a zip, it requires the zip to have two pull tabs. Furthermore, this method tends to substantially increase the time it takes for a rightful owner to access a cavity (since that owner must unlock the lock), and therefore the use of such locks is rare.

Referring to Figure 2, there is shown a zip restraint according to the present disclosure The zip restraint 100 is arranged to attach (typically releasably) to the material to either side of the rows of teeth of a zip and to hinder or prevent the movement of the slider along these rows of teeth. The zip restraint could equally be called a zip lock, zipper lock, or zippy lock.

To prevent the movement of the slider 14 along the rows of teeth 12, the zip restraint typically comprises a body that is located over the zip when the zip restraint is attached to an object; this body obstructs the slider and thereby prevents the operation of the zip. Additionally, or alternatively, the zip restraint may use a pinching mechanism to hinder the movement of the slider.

The zip restraint is typically used to prevent the opening of the zip. It will be appreciated that the zip restraint can equally be used to prevent the closure of the zip.

Referring to Figures 3a and 3b, there is illustrated the operation of an embodiment of a zip restraint according to the present disclosure.

Figure 3a shows a zip before the zip restraint 100 is applied to the zip. As can be seen, with this situation, the slider 14 is able to move along the rows of interleaving teeth 12 in order to operated (e.g. open or close) the zip.

Figure 3b shows the zip after the zip restraint 100 has been applied. As show, the zip restraint straddles the zip and attaches to the material to either size of the zip. The zip restraint comprises a pinching mechanism that is arranged to pinch the zip so as to hinder or prevent the movement of the slider 14 along the rows of interleaving teeth 12 as the slider approaches the zip restraint. The zip restraint (and the pinching mechanism) may be size so as to pinch the material (e.g. the tape) directly adjacent the rows of teeth, or the zip may be sized so as to pinch to material further from the zip.

The zip restraint 100 may comprise an attachment structure for attaching the zip restraint to the material; for example, the zip restraint may comprise an adhesive structure, or a clip that attaches the zip restraint to the material. Typically, the zip restraint is attached to the material using the pinching mechanism. In such embodiments, the pinching mechanism is used both to attach the zip restraint to an object and to pinch the zip so as to hinder the movement of the slider 14. By using the pinching mechanism to serve both of these purposes, a compact zip restraint can be provided.

In embodiments with a separate attachment mechanism, the zip restraint may be sized so that the zip can be operated when the pinching mechanism is in an inactive position. Then when the zip restraint is moved to an active position, the pinching mechanism prevents the movement of the slider 14 and the operation of the zip. Such embodiments enable the zip restraint to remain attached to an object for ease of use.

As shown in Figure 3b, the zip restraint 100 may be arranged so that the pinching mechanism does not enclose the rows of interleaving teeth. It will be appreciated that the reach of the pinching mechanism may be varied and that the zip restraint may be designed so that when the zip restraint is attached to an object the pinching mechanisms extend at least partially between the rows of interleaving teeth of the zip and the remainder of an object. Such embodiments provide a secure attachment, since the rows of interleaving teeth interact with the pinching mechanism to hinder removal if the zip restraint is detached when the pinching mechanism is in an active position.

In this regard, the zip restraint 100 is arranged to be placed around an object and the pinching mechanism is arranged to move between an inactive position, where the pinching mechanism does not grip the object, and an active position, where the pinching mechanism grips the object.

Referring to Figure 4, there is shown a first embodiment of the zip restraint 100. In this embodiment, the pinching mechanism comprises a first arm 102 and a second arm 104, where the first arm and the second arm are associated with, respectively, a first button 112 and a second button 114.

The first arm and the second arm are biased towards an inactive position by a biasing mechanism 108, such as a spring.

In use, a user places the zip restraint 100 around a zip and then presses the first button 112 and the second button 114 to move the first arm 102 and the second arm 104 together to an active position in which the arms pinch the material around the zip. This both attaches the zip restraint to an object associated with the zip and prevents the movement of the slider 14 along the rows of teeth 12 of the zip.

The first arm 102 and the second arm 104 are arranged so that as the first arm and the second arm are pushed together towards the active position, a hook of each arm passes into a hole 106. Therefore, when the first button 112 and the second button 114 are released, the arms abut the sides of the hole so that the biasing mechanism 108 is not able to push the arms back to the inactive position. Therefore, the pinching mechanism remains in the active position and the zip restraint is attached to the object.

So that the pinching mechanism can be returned to the inactive position, the zip restraint comprises a release button 116. The release button is capable of pushing the hooks of the arms through the hole 106 so that the force applied by the biasing mechanism 108 can move the first arm 102 and the second arm 104 to the inactive position. The zip restraint can then be removed from the object.

More generally, the active position is typically a stable position, wherein a force is required to move the pinching mechanism out of the activation position. More specifically, in order to move the pinching mechanism out of the activation position a release mechanism must be operated. Typically, the zip restraint comprises a biasing mechanism that, when the pinching mechanism is away from an active position, acts to move the pinching mechanism to an inactive position.

To hold the pinching mechanism in the active position, the zip restraint 100 typically comprises a holding structure and/or holding mechanism (e.g. the hole 106). It will be appreciated that other holding structures are possible (e.g. ratchets, levers, detents, etc.). The holding structure may be operated by the release mechanism (e.g. the holding structure may comprise a ratchet that is turned by the release mechanism) or the holding structure may be a passive component such as the hole.

Typically, the release mechanism 116 (and/or the holding structure) is arranged so that a threshold magnitude, distance, angle, and/or duration of force is required to move the pinching mechanism out of the active position. With the embodiment of Figure 4, the portions of the arms that protrude through the hole 106 may be sized so that the release button 116 must be pressed a threshold distance to displace these arms from the hole. This prevents the inadvertent operation of the release mechanism.

To move the pinching mechanism out of the active position, the release mechanism 116 may be arranged to require one or more of: a force with a magnitude of at least 5N, at least 10N, at least 25N, at least 50N, at least 75N, and/or at least 100N; a force that is applied for at least one second, at least two seconds, at least five seconds and/or at least ten seconds; a force that is applied over: a distance of at least 10mm, at least 20mm, at least 50mm, and/or at least 100mm; and/or an angle of at least 30 degrees; an angle of at least 60 degrees; an angle of at least 90 degrees; an angle of at least 180 degrees; and/or an angle of at least 360 degrees.

A threshold magnitude may be implemented by using a stiff button that requires a certain force to push. A threshold duration may be implemented using a timer (e.g. so that a user might need to hold down a button for a certain amount of time), this may require the zip restraint to comprise a power source. Equally, a threshold duration may be implemented mechanically (e.g. using a wheel that is turned to operate the release mechanism and determining a max rate of turning of the wheel). A threshold distance may be implemented as described above with the arms 102, 104 and the hole 106. A threshold angle may be implemented using release mechanism that is a cog and/or wheel.

In some embodiments, the release mechanism comprises a liveness detector (e.g. a projected capacitive screen) that can distinguish between a live touch and an inanimate object such as a wall. This further prevents inadvertent operation of the release mechanism.

It will be appreciated that the embodiment of Figure 4 is exemplary and that the features may be modified without straying from the scope of the disclosure.

In general, the zip restraint 100 comprises at least one of: -An attachment mechanism for attaching the zip restraint to an object.

A pinching mechanism for attaching the zip restraint to an object and/or for hindering the movement of a slider of a zip. Typically, the attachment mechanism and the pinching mechanism are combined into a single mechanism that both attaches the zip restraint to an object and pinches a zip of that object. Equally, the attachment mechanism and the pinching mechanism may be separate mechanisms so that the user can move the pinching mechanism between the inactive and active positions without the zip restraint detaching from the object.

-An activation mechanism that moves the pinching mechanism from an inactive position to an active position (e.g. the first button 102 and/or the second button 104).

A release mechanism (e.g. the release button 116) that moves the pinching mechanism from an active position to an inactive position. The activating mechanism and the release mechanism may be combined into a single mechanism. The release mechanism may be arranged to prevent accidental operation of the release mechanism; for example, the zip restraint may comprise a cover for covering the release mechanism (e.g. a hinged flap and/or the release mechanism may be located in a recess of the zip restraint.

In some embodiments, the release mechanism requires two different movements to operate (e.g. twist and then pull). Such a mechanism prevents inadvertent release of the zip restraint and also prevents rapid operation by a pickpocket. The two movements may comprise movements in different directions and/or angles. Equally, the two movements may comprise movements with two different forces and/or accelerations. In some embodiments, the different movements comprise movements to unlock a locking mechanism and then to deactivate the activation mechanism (e.g. the first movement may involve operating a combination lock). In some embodiments, the two different movements are performed by two different hands; for example, the release mechanism may comprise two component parts that must be operated simultaneously, where these components parts may be located on different portions of the zip restraint 100 so that they cannot be operated with a single hand.

Typically, the zip restraint 100 further comprises a biasing mechanism 108 that is arranged to bias the pinching mechanism towards the inactive position.

Referring to Figures 5a and 5b, there is shown a second embodiment and a third embodiment of the zip restraint 100.

The second embodiment, as shown in Figure 5a, comprises a fixed second arm 104 as well as a moveable first arm 102 that is moved towards an active position by a user pressing the first button 112. In the active position the moveable first arm cooperates with the (fixed) second arm to pinch the material to either side of a zip.

As with the first embodiment, the first arm 102 is locked in the active position by a hook of the first arm passing through a hole 106 and abutting a side of the hole. The first arm can be returned to an inactive position by a user pressing a release button 116 that pushes the hook back through the hole so that a biasing mechanism 108 is able to force the first arm towards an inactive position.

In the third embodiment, as shown in Figure 5b, the release mechanism is combined with the activation mechanism (e.g. the release button 116 is combined with the first button 112). A user pressing the first button a first time secures the first arm 102 (and the pinching mechanism) in the active position. A user pressing the first button a second time releases the first arm so that the biasing mechanism is able to return the first arm (and the pinching mechanism) to the inactive position.

Such a combined activation/release mechanism may work by rotating the first arm 102 as the first button 112 is pushed so that when the first button is released a protrusion of the first arm fits into a recess of the zip restraint (which recess keeps the first arm in the active position). When the first button is pushed again, the first arm is rotated further so that when the first button is released the protrusion of the first arm is outside of the recess and the first arm is able to return to the inactive position. Such combined activation and release mechanisms are well known in other areas of technology and are, for example, commonly found in pens. It will be appreciated that many other mechanisms of securing and releasing components (using either a single activation/release mechanism or separate activation and release mechanisms) are known and may be used with the zip restraint.

The use of buttons for the activation mechanism and/or the release mechanism provides a low profile mechanism that leads to a compact zip restraint. However, other components may be used to move the pinching mechanism between the active and inactive positions, for example: levers or cam levers, cogs or wheels, spring loaded components, and flexible materials (e.g. metals or plastic).

The zip restraint 100 as disclosed provides a device that is able to prevent the undesired opening of a zip while being simple for a user to attach and remove. Furthermore, unlike many conventional zip restraints, the zip restraint disclosed herein is suitable for use with zips with a single slider and can be easily moved between objects so that a user is able to quickly and easily secure zips even on new items.

In order to increase the security provided by the zip restraint 100, many embodiments of the zip restraint comprise further components/features. For example: The zip restraint 100 may comprise a locking mechanism, such as a biometric scanner (e.g. a fingerprint scanner or a camera capable of facial identification), a key lock, a combination lock, or a dial lock. The locking mechanism requires knowledge, material, and/or time to operate. Typically, the locking mechanism requires a factor which is known only by the user (so that a pickpocket is not able to operate the locking mechanism). Equally, the locking mechanism may require time to operate; for example the locking mechanism may require a plurality of different movements to operate so that a pickpocket is not easily able to operate the locking mechanism without being detected (and the simple presence of such a locking mechanism would act as a deterrent).

The locking mechanism is arranged so that the locking mechanism must be operated to operate the release mechanism and to move the pinching mechanism from the active position to the inactive position. The locking mechanism may be a part of the release mechanism (so that any of the features described with reference to a locking mechanism may be implemented as a part of a release mechanism) and/or the release mechanism may comprise a locking mechanism; for example where the locking mechanism comprises a biometric scanner, the operation of the scanner may move the pinching mechanism to the inactive position. The locking mechanism may also be a separate mechanism, so that the user may operate the locking mechanism to access the release mechanism (e.g. the locking mechanism may comprise a flap that covers the release mechanism); this is of particular benefit when the locking mechanism is operated automatically (e.g. using a proximity sensor or a facial scanner).

In various embodiments, the locking mechanism comprises one or more of: * A combination lock where the dials need to be correctly lined up in order for the release button 116 to be operated. In some embodiments, the operation of the combination lock also operates the release device (e.g. the release button may automatically pop open when the dials are correctly lined up.

* A dial lock where a protrusion of a dial need to be correctly lined up with a recess. More specifically, to operate the dial lock, a dial of the dial lock must be rotated to a position where a protrusion of this dial lines up with a recess of a base of the dial lock. The dial may then be pulled or pushed to operate the locking mechanism. Equally, the dial may comprise a recess and the base may comprise a protrusion.

* A lock and key.

* A biometric lock (e.g. a lock that requires facial recognition or a fingerprint).

* An electronic lock (e.g. that can be unlocked via an application).

* A voice controlled lock.

* A puzzle lock (e.g. where only a user knows the solution to the puzzle). This may for example, comprise a puzzle in which a puzzle piece needs to be placed in a certain position to operate the lock.

- The zip restraint 100 may be arranged to provide a output (e.g. a notification or a sensory output such as a noise, a vibration, or a light) when the release mechanism and/or the locking mechanism is operated so that a user is alerted if a pickpocket attempts to access their bag. This may comprise, for example, the zip restraint comprising a noise-making mechanism or the pinching mechanism being arranged to rapidly move from the active position to the inactive position and to impact a surface at the inactive position. The zip restraint may be arranged to make a loud noise when the release mechanism is operated quickly but not to make a loud noise when the release mechanism is operated slowly (e.g. when a user smoothly presses and releases the release button 116). This enables a user who is able to take their time to quietly remove the zip restraint. Similarly, the zip restraint may be arranged to make a (loud) noise when a locking mechanism is incorrectly operated (e.g. when an incorrect code is input to a combination lock) and/or when an attempt is made to remove the zip restraint without operating the release mechanism and/or the locking mechanism. Where the output comprises a noise, the zip restraint may be arranged to output a noise greater than 50dB, greater than 60dB, greater than 70dB, greater than 80dB, greater than 90dB and/or greater than 100dB.

The zip restraint 100 may comprise one or more of: a processor, a power source (e.g. a battery), a communication interface (e.g. a Bluetooth® interface, or a 3G, 4G, or 5G interface), a sensor, a microphone, and a speaker. Such components may enable the zip restraint 100 to communicate with a further device, such as a user's smartphone or smartwatch, to operate the pinching mechanism, the release mechanism, the locking mechanism, and/or the noise-making mechanism. In a practical example, the user may connect their phone to the zip restraint so that the pinching mechanism moves to the inactive position when the user unlocks their phone and/or when the user enters a certain location. This enables the user to set the pinching mechanism to unlock automatically when the user returns home. Similarly, the user may configure the pinching mechanism to move between the active position and the inactive position based on a voice command. The zip restraint may be arranged to transmit a signal to a separate device (e.g. a user's smartphone) when the pinching mechanism and/or the release mechanism is operated; for example, a user's smartphone or smartwatch may vibrate when the pinching mechanism is moved from the active position to the inactive position.

The zip restraint 100 may be arranged to provide an output (e.g. a notification or a sensory output) in dependence on the pinching mechanism being operated when a user is more than a threshold distance from the zip restraint (the distance of the user may, for example, be determined based on the location of a user's smartphone) and/or in dependence on a context of the user. For example, the zip restraint may provide an output if the pinching mechanism is operated while the user is travelling or moving or if the user is in a certain location.

Typically, the zip restraint 100 comprises a keyring and/or another external attachment mechanism that enables the user to secure the zip restraint when the zip restraint is removed from the object.

Typically, the zip restraint 100 is sized compactly so that the zip restraint hinders the movement of the slider 14 even when the pinching mechanism is in the inactive position (and. In such embodiments, the zip restraint is arranged to be removed from the object so that the zip can be operated). In some embodiments, the zip restraint 100 is sized to allow the passage of the slider when the pinching mechanism is in the active position. More specifically the zip restraint may be sized so that the slider (and the pull-tab 16) is able to move along the rows of teeth 12 when the pinching mechanism is in the inactive position and is prevented from moving only when the pinching mechanism is in the active position. This may comprise the zip restraint comprising elongated columns that are joined by a connecting portion, where, in use, the connecting portion is far enough from the zip to allow the slider to comfortably pass between the columns.

In order to enable easy movement of the zip, the zip restraint 100 may be provided in two parts (e.g. where one part of the zip restraint is located to each side of the zip). Such an arrangement risks the user losing one of these parts, so such an arrangement is particularly beneficial where the zip restraint is integrated with an object. In such an embodiment, the user can leave the zip restraint on an object and simply operate the pinching mechanism whenever they wish to secure the zip. The slider 14 (and the pull-tab 16) are able to pass between the two parts of the zip restraint when the pinching mechanism is in the inactive position. When the pinching mechanism is in the active position, the pinching mechanism prevents the slider from moving along the zip.

Typically, the pinching mechanism comprises two components (e.g. two arms) that are arranged to be located to either side of a zip. In some embodiments, the pinching mechanism comprises a single component, e.g. a single arm, that is located to a single size of a zip. Such embodiments typically comprise a separate attachment mechanism to ensure that the zip restraint can be securely attached to an object.

The present disclosure extends to an object (e.g. a bag or a garment) that comprises the zip restraint 100. The zip restraint may be a removable component or may be an integral part of the object. In such embodiments, the zip restraint is typically arranged so that the slider can pass along the zip when the pinching mechanism is in the inactive position.

Referring to Figure 6, there is shown an exemplary locking mechanism that is a dial lock 120.

A dial 122 of the dial lock 120 comprises a protrusion 124. A base 126 of the dial lock comprises a recess 128. In order to operate the dial lock (e.g. to press the dial lock), the dial must be rotated until the protrusion lines up with the recess.

Such a locking mechanism may be combined with the release button 116 so that pressing the dial 122 operates the release mechanism.

As mentioned above, the dial lock 120 could be modified so that the dial 122 comprises a recess that must be aligned with a protrusion in the base 126 to enable the pressing (or pulling) of the dial.

Typically, the recess 128 is obscured. For example, a portion of the dial 122 of the dial lock 120 may protrude through a shroud that obscures the recess 128. The shroud may comprise a series of characters, symbols, or colours that help a user to align the protrusion 124 with the recess 128. A pickpocket who is unaware of the relationship between the characters and the alignment position will not be easily able to align the protrusion with the recess.

For embodiments where further security is desired, a dial lock with a plurality of dials may be provided, e.g. three dials could be located on a single base that has three separate recesses, or a dial could be provided with a plurality of staggered protrusions.

Referring to Figures 7a, 7b, and 7c there is shown a fourth embodiment of the zip restraint 100.

In the fourth embodiment, the biasing mechanism 108 comprises a first ball plunger that biases the first arm 102 of the zip restraint towards an inactive position. The holding structure 106 comprises a second ball plunger that is arranged to extend into a cavity in the active position.

Referring to Figure 7a, the first ball plunger 108 biases the first arm towards the inactive position. In this inactive position, the second ball plunger 106 is compressed by a portion of the zip restraint 100.

Referring to Figure 7b, a user is able to move the first arm 102 towards the active position against the bias of the first ball plunger 108. This movement causes the second ball plunger 106 to reach the cavity and to expand into the cavity so as to hold the first arm, and the pinching mechanism, in the active position.

Referring to Figure 7c, when the user wishes to remove the zip restraint 100, the user depresses the second ball plunger 106 to move the second ball plunger out of the cavity. The first ball plunger 106 then acts to return the first arm 102, and the pinching mechanism, to the inactive position.

To hinder accidental or malicious depression of the second ball plunger 106, the zip restraint may comprise a cover that can be placed over the second ball plunger (e.g. a cover that is arranged to move over the second ball plunger as the first arm 102 is moved to the active position).

Alternatives and modifications It will be understood that the present invention has been described above purely by way of example, and modifications of detail can be made within the scope of the invention.

For example, while the activation mechanisms and release mechanisms considered in the detailed description have primarily comprised buttons, it will be appreciated that many other mechanisms are usable (e.g. pincers, cogs, deformable materials). It will also be appreciated that many arrangements of the activation and release mechanisms are possible, e.g. these mechanisms may be located on various parts of the zip restraint 100.

For example, the arms of the pinching mechanism may each be connected to a cog that can be turned in a first direction to move the arms towards the active position and that can be turned in a second direction to move the arms towards the inactive position. The cog may comprise a ratchet that is associated with a locking mechanism so that the cog can only be moved in the second direction by operating the locking mechanism.

Equally, the pinching mechanism may comprise a clip, so that a user is able to squeeze the two ends of the clip to move the pinching mechanism to an inactive position and the user can then place the pinching mechanism on an object and release the clip.

While the detailed description has primarily considered a pinching mechanism that is biased away from an active position, in some embodiments the pinching mechanism is biased towards the active position. In such embodiments, the user is able to operate a release mechanism to move the pinching mechanism to the inactive position. The user can then place the zip restraint 100 over a zip and release the release mechanism so that the pinching mechanism returns to the active position.

While the detailed description has primarily considered a pinching mechanism that comprises one or two arms, it will be appreciated that the pinching mechanism may comprise ay number of arms (e.g. the pinching mechanism 3, 4, 5, or 6 arms). Furthermore, the pinching mechanism may use other methods of pinching, such as one or more fans that pinch material using high powered jets of fluid.

In some embodiments, the zip restraint 100 comprises a slider attachment for attaching to the slider 14 and/or to the pull-tab 16. This enables the zip restraint to be attached to the slider when it is not in use so that it does not get lost. Furthermore, this enables the zip restraint to be attached to the slider and/or the pull-tab when the pinching mechanism is in the active position to hold the slider in place. So the zip restraint may be placed to one side of the slider so that the pinching mechanism prevents the slider from moving in a first direction (e.g. towards the zip restraint) and so that the slider attachment prevents the slider from moving in a second direction (e.g. away from the zip restraint).

In some embodiments, the zip restraint 100 comprises a component for covering the pull-tab 16. For example, the zip restraint may be sized so that the body of the zip restraint covers the pull-tab when the zip restraint is attached to an object. Equally, the zip restraint may comprise a separate pull-tab cover that can be placed over the pull-tab once the zip restraint has been attached to this object. The pull-tab cover may be associated with the activation mechanism and/or the locking mechanism so that the removal of the pull-tab cover from the pull tab is dependent on the operating of one or both of these mechanisms. Such a pull-tab cover is of particular benefit for zips with sliders that are not able to move when the pull-tab is in a downwards position.

Reference numerals appearing in the claims are by way of illustration only and shall have no limiting effect on the scope of the claims.
