1. Field of the Invention
The present invention relates to securing hand held personal articles and more particularly for tethering personal electronic devices such as cell phones, pagers and PDA'S.
2. Description of the Related Art
Personal hand held electronic devices such as cell phones, pagers, and PDA's have become very popular in recent years. These devices are designed to be highly portable and capable of being carried by their owners throughout the day. When not in use, it is desirable to keep these devices conveniently within arms reach while at the same time not having to hold the devices. They can be held on the owner's body by a clip mount, holster or storage pocket. For example, cell phones made by Nokia can come with a clip mount that attaches to the user's belt or waste band and has a notch that mates with a pivoting ball on the back of the phone. The ball is inserted within the notch and the ball and notch combination holds the phone to the clip mount.
One disadvantage of most conventional clip mounts, holsters and storage pockets, is that the electronic device that they are holding can be jarred loose and fall to the ground where it can be lost or damaged. Also, when the electronic devices are removed from their clip mount, holster or storage pocket for use, they can be dropped. This can also result in the devices being lost or damaged.
Retractable tether apparatuses are available that have a line/tether that can be pulled from the apparatus' housing and when released, the line/tether automatically retracts into the housing. These apparatuses can be used with hand held electronic devices to prevent them from falling to the ground if they are dropped or jarred loose. One such device is disclosed in U.S. Pat. No. 5,938,137 to Poulson and comprises a leash attached to the cell phone case and a spring retractable leash cord in a housing pivotally attached to the user's belt. This arrangement helps prevent dropping and damage to a cell phone in a case clipped to the belt. The leash housing is pivotally attached to a locking belt hook that cannot easily be accidentally removed.
One disadvantage of these apparatuses is that they comprise a separate device that is usually mounted to user adjacent to the mounting point for the electronic device. This results in an additional device that is mounted to the body, that is then attached to the electronic device that is also mounted to the body by a separate clip mount, holster or storage pocket. This arrangement can be bulky and difficult to use.
U.S. Pat. No. 6,206,257 discloses a swivel belt clip with bi-directional action, comprising a releasable holder for a portable communication device that includes a base clip adapted to secure to a belt in a horizontal orientation. An article clip is secure to a portable communication device. The base clip includes a channel and a locking tab extends into an opening in the channel bottom. Two user engageable release tabs adjacent the channel opposite ends are adapted to move the locking tab in response to movement of one release tab toward the other. The article clip includes a locking head adapted to slide in the channel, with the locking head adapted to receive the locking tab when the two are aligned to hold the article in the clip. Movement of the release tabs disengage the locking tab from the locking head so that the article can be removed from the clip.
One embodiment of a tethering system according to the present invention comprises a tether housing having an internal tether that is extendable from the tether housing under a pulling force and retracts into said tether housing when the pulling force is removed. A mounting apparatus is included that is integral to the tether housing and arranged to mount the tether housing. A holstering system is included and is integral to the tether housing and arranged to allow a personal device to be mounted to the tether housing with the tether attached to the personal device. The tether is extendable to allow use of the personal device while also preventing the personal device from falling to the ground when the tether housing is mounted.
Another embodiment of a tethering system according to the present invention comprises a housing having front and back surfaces and a tether internal to the housing. A spring is also internal to the housing and arranged to allow the tether to be extended from the tether housing against the force of the spring, with the spring urging the tether to retract into the housing. A mounting apparatus is included on the back surface of the tether housing and is arranged to mount the tether housing to a person. A holstering system is included on the front surface of the tether housing and arranged to allow a personal device to be mounted to the tether housing with the tether attached to the personal device. The tether is extendable to allow use of the personal device by the person. The spring and tether also prevents the personal device from falling to the ground.
These and other further features and advantages of the invention will be apparent to those skilled in the art from the following detailed description, taken together with the accompanying drawings, in which:
The present invention provides an improved security-tethering system that can be used in many different applications, but is particularly adapted for use with hand held personal electronic devices.
In the tethering system 10, the holstering attachment 14 can be arranged in many different ways and as shown in
The system's retractable tether apparatus 12 has a housing 16 that houses the line/tether (“tether”) that protrudes from the housing through opening 17. The housing 16 also includes an internal spring that biases the tether to retract back into the housing 16. A lanyard attachment 18 (shown in
As shown in the embodiment of
It can be appreciated that tethering systems according to the present invention incorporate a retractable tether apparatus 12 and electronic device holstering system 14 in one assembly, with the holstering system 14 being integral with one of the surfaces of the retractable tether's housing 16. The tethering system 10 can be mounted on the user's belt or waste band and an electronic device can be mounted to the holstering system 14 so that the electronic device is securely mounted to the tethering system 10. The tether from the retractable tether apparatus 12 is attached to the electronic device and retracts from the tether housing 16 when the electronic device is in use. If the electronic device is dropped during use or is jarred from the holstering system 14, the tether does not retract from the tether apparatus 12 under the weight of the electronic device. This prevents the electronic device from falling to the ground. By incorporating the holstering system and tether into one device, a tethering system is provided that is less bulky and easier to use.
The lanyard loop 24 provides for a section of line between the electronic device 20 and lanyard attachment 18 so that the tether can be in its fully retracted position when the electronic device 20 is mounted to the system 10, while at the same time not placing tension on lanyard loop 24. This allows the electronic device 20 to be mounted to the tethering system without placing stress on the tether or lanyard attachment 18 and not pulling the electronic device 20 from the holstering system on the tethering system housing. This makes the system 10 easier and more convenient to use and extends the life of the system components.
The lanyard loop 24 can be attached to the electronic device in different ways such as to a ring on the device's protective case, or directly to the pivoting ball connector type mount. In electronic devices that do not have these attachment features, the lanyard loop 24 can be attached in other ways according to the present invention.
Referring again to
The holstering system 14 can also include a holds pin, which is known in the art and is arranged to holds the pivoting ball within the holstering system 14. To remove the cell phone from the holstering system 14 for use, a lever on the attachment 14 is activated to retract the pin and release the pivoting ball. The phone can then be removed from the holstering system 14 and pulled to the user's ear. The tether is pulled from the retractor housing 16 under the pulling force, but the tension required to extend the tether is not so great that it interferes with the use of the phone. If the phone is dropped at any point during is use, the tether prevents it from falling to the ground. When the phone is done being used it is moved back to the tethering system 10 where it can be remounted in the holstering system 14. The tether automatically retracts into the housing. When not in use, the device is securely mounted to the front of the tethering system.
During use of the tethering system 10 the lanyard attachment 18 and tether extend upward from the housing, which is particularly convenient for devices that are used above the mounting point of the system 10, such as with cell phones. In other embodiments, the line/tether can protrude outward from the housing and away from the user, which is particularly convenient for devices used at approximately the same height as the mounting point for the tethering system 10. For example, when a PDA is used it is held in front of the user, which can be more compatible with an outward protruding tether. The tethering system 10 can also include a disconnect means so that the electronic device 22 can be detached from the lanyard attachment 18. In another embodiment, the tethering system 10 is arranged so that it can also rotate about the user's belt or waste band by the clip 19.
The holstering system 46 is U-shaped and sized to fit the same pivoting ball used for the Nokia type holstering attachments. It is, however, longer than the Nokia type attachments and does not have a retaining pin. The holstering system 46 has three mounting points to the housing 42 with the first and second mounting points 48, 50 near the base of holstering system 46, and the third attachment point 52 being at one of the legs of the holstering system 46. The other leg 54 is not attached to the housing 42, but instead serves as a “living hinge” to hold the pivoting ball in the holstering system 46. As the pivoting ball passes into the attachment 46 the pivoting ball forces the leg 54 to flex out, increasing the size of the opening in the holstering system 46. As the pivoting ball passes through the opening, the leg 54 flexes back in, reducing the size of the opening. This reduction in the size of the opening helps hold the cell phone in the holstering system 46 when the cell phone is not in use. If the jarring force is great enough to force the pivoting ball past the leg 54, the holstering system 46 will not be damaged and the tether prevents the phone from falling to the ground.
Tethering system 10 and 40 also include a ratchet lock system that allows the tether to be retracted and held at its retracted length with no retracting bias on the tether. To release the tether so that it retracts, it is pulled, which releases the ratchet lock. The housings 16 and 42 each include a ratchet lock on/off lever 19, 55 that allows for the user to disable the ratchet locking system. When the system is disabled, the bias remains on the tether when the phone is in use.
Although the present invention has been described in considerable detail with reference to certain preferred configurations thereof, other versions are possible. As described above, different holstering attachments can be used with different electronic devices. Also, different retractable tether apparatus can be used in accordance with the present invention. Therefore, the spirit and scope of the invention should not be limited to the preferred versions in the specification.
