Description
BACKGROUND INFORMATION
[0001] 1. Field of the Invention
[0002] The invention relates to the field of article carriers and,
particularly, to cases or carriers for handheld electronic devices.
More particularly, the invention relates to tethered holders, which
facilitate retrieval of such devices from a larger storage
area.
[0003] 2. Description of the Prior Art
[0004] Handheld electronic devices are ubiquitous in today's world.
People routinely carry PDAs, cell phones, pagers, and other
devices. For the sake of simplicity, reference shall be made to a
cell phone hereinafter, although it is understood that this term is
also representative of PDAs, pagers, and other handheld electronic
devices. Men typically carry such devices, when not in use, in
their pants pocket or clipped to their pants belt, so they are
generally readily accessible. Women, on the other hand, generally
carry such devices in a handbag. When the phone rings, the user
then has to quickly locate the cell phone in the handbag and
retrieve it before the caller has given up and terminated the call.
The problem with storing a cell phone in a handbag is, that the
phone, being small and denser than other objects in the handbag,
sinks to the bottom of the bag. Depending on the size and contents
of the bag, it may take some time to locate and retrieve the
device. The same problem applies when carrying the cell phone in a
back pack, tote bag, book bag, or other large carrier.
[0005] One solution to the problem above is to attach a tether to
the device. Many embodiments of a spooled tether are known.
Typically, a case for the handheld electronic device is attached to
a belt. Also attached to the belt is a spooled tether case. The end
of the tether is attached to the electronic device. The tether is
generally spring-biased to retract automatically into its case.
This allows the tether to remain on the device during use, yet
allow sufficient freedom of movement so that the device can be used
comfortably for its intended function. That is, the device can
comfortably be raised to the ear or held in the hand. This system
also works well for key rings, which are attached to the end of the
tether and are carried close to the spooled tether case.
[0006] This type of tether system is not particularly suitable for
use with cell phones that are stored in a handbag or other type of
bag. If the spooled tether case is attached to some strap or loop
in the bag, the user is forced to use or at least respond to a call
on the cell phone in close proximity to the bag, and this is not
always convenient.
[0007] What is needed, therefore, is a device for tethering a
handheld electronic device to a handbag or tote bag for quick
retrieval, that will instantly allow untethered use of the
device.
BRIEF SUMMARY OF THE INVENTION
[0008] The invention is a tethered holster for holding a handheld
electronic device. The handheld electronic device may be a cell
phone, PDA, pager, or other device that is typically carried in a
handbag, back pack, book bag, or tote bag, and that is typically
held by the user during use. The term "cell phone" or "phone" is
used hereinafter as representative of handheld electronic devices.
The holster is adapted to hold the handheld electronic device
securely, while providing ready access to the operational features
of the device. A tether is releasably attached to the holster. A
cell phone user generally wants to be able to respond to an
incoming call quickly and to use the phone without being restrained
in freedom of movement. For this reason, the tethered holster
according to the invention has a instant-release button that
immediately releases the end of the tether from the holster.
[0009] The tethered holster comprises a shell or case that holds
the cell phone or electronic device, such that it may be used while
still held in the shell. A tether is releasably attachable to a
catch device on the shell. The other end of the tether may be
attached to or wrapped around another object, such as the strap or
handle of a handbag, backpack, etc., so as to tether the case to
the object. This allows the user to quickly locate the proximal end
of the tether and to pull on it to retrieve the shell or case that
is attached to the distal end. The distal end of the tether has a
post with an anchor head that is releasably restrained within the
catch device. The catch device is spring loaded, so that the catch
is biased to a catch position that secures the anchor head within
the catch device. A catch release, such as a push-button, works
against the spring bias to open the catch. An ejection spring
placed beneath the catch forces the anchor head out of the catch
device when the catch release is actuated. In this manner, the
tether is quickly released from the shell by the push of a button,
so that the user may use the cell phone in the shell, without any
restraints on personal movement.

DETAILED DESCRIPTION OF THE INVENTION
[0036] The present invention will now be described more fully in
detail with reference to the accompanying drawings, in which the
preferred embodiments of the invention are shown. This invention
should not, however, be construed as limited to the embodiments set
forth herein; rather, they are provided so that this disclosure
will be complete and will fully convey the scope of the invention
to those skilled in the art.
[0037] FIGS. 1 and 2 show a holster 1000 according to the
invention, for holding a small handheld electronic device ED. The
holster 1000 is constructed to allow ready access to the
operational features of the electronic device ED while it is held
in the holster. The holster 1000 has a case 100 formed of side
walls 102, a bottom wall 104, a back wall 112, and a catch device
200 mounted on the back wall. A continuous lip 106 on the edge of
the back wall 112 and side walls 102 defines a storage area 108 on
the case 100.
[0038] FIG. 3 shows a tether 400, which has a tether line 420, the
ends of which are captured in a tether post 410. A post end 412 has
an anchor head 414. FIG. 4 is a perspective view of the catch
device 200, shown without the case 100. The catch device 200
comprises a catch 260 for releasably holding the anchor head 414
and a catch release 220. The anchor head 414 is shown captured in
the catch 260. The catch release 220 in the embodiment shown is a
button 230, which, when pushed, opens the catch 260, allowing the
tether 400 to be quickly and easily released from the case 100.
[0039] FIGS. 4A-9B illustrate the construction and various features
of the catch device 200 and FIG. 10 is a partial assembly drawing,
showing the internal catch components in their assembled position.

the catch release 220, and FIG. 4D a cross-sectional view showing
the anchor head 414 of the tether post 410 held in the catch 260.
The catch 260 and the catch release 220 are enclosed in a housing
300 that comprises an upper housing 310 and a backplate 330. The
catch release 220 includes the button 230 that is spring biased by
a first spring 232 to hold the catch 260 in a restraining position.
A more detailed discussion of the cooperation among the various
components to actuate the catch 260 and the catch release 220
continues below, after the individual components have been
explained.
[0040] FIGS. 5-5B show the inside of the upper housing 310, which
has a button aperture 332 that provides access to the button 230
and a post aperture 336 into which the tether post 410 is inserted
into the catch 260. Mounting holes 302 are provided for mounting
the catch device 200 to the case 100.
[0041] FIG. 6 shows the underside of the button 230, which has a
first push block 234 and a post 232A on which the first spring 232
is assembled. FIGS. 6A-6C illustrate the contours of the button 230
and push block 234.
[0042] FIG. 7 is a perspective view 330 and FIG. 7A a top plane
view of the backplate 330. The backplate 330 has various features
that are constructed to hold a slider assembly 270, which will be
described in connection with FIGS. 8-8B below. Mounting holes 332
are provided, for attached the catch device 200 to the case
100.
[0043] FIG. 8A is a top plane view of the slider assembly 270,
which is assembled on and slides along the backplate 330 to open or
close the catch 260. The slider assembly 270 comprises a slider
body 278, a leaf spring 274 that extends across a slider aperture
271, cam surfaces 276, a second push block 275, and a second
biasing spring 272. FIG. 8C shows the contour of the leaf spring
274. FIG. 8 is a perspective view of the slider body 278, shown
from its underside, without the leaf spring 278 and the second
biasing spring 272 assembled.
[0044] FIGS. 9-9C illustrate a post prong 240 which has a recess
240A, a spring receiving groove 240B for retaining a third biasing
spring 242, and a push surface 246. A pair of prongs 240 is
assembled within the upper housing 310. During assembly, the prongs
240 are held in place by a lubrication substance that is applied to
a surface of the prong, which is then pressed against the inner
surface of the housing 310. Once the housing 310 is assembled on
the backplate 330, the confines of the housing 310 and backplate
330 serve to hold the prongs 240 in their operative positions. The
lubrication serves as a glide adhesive: it initially holds the
prongs in position, yet allows the prongs to slide between a catch
position and a release position, to be discussed with reference to
FIG. 10.
[0045] FIG. 10 is a partial assembly drawing of the catch device
200, with the upper housing 310 removed, and which illustrates the
catch and catch-release operations of the catch device 200. The
slider 278 is assembled on the backplate 330, such that it is
movable in the longitudinal direction, indicated by a first
directional arrow A1. The catch release elements that are assembled
in the upper housing 310 are shown with dashed lines, superimposed
over the slider assembly 270. The button 230 with its first push
block 234 is positioned above the second push block 276 on the
slider 278. The pair of prongs 240 are movably retained within the
upper housing 310. A third biasing spring 242 on each prong 240
biases the prongs toward the center of the catch device 200. The
recesses 240A are dimensioned such, that they encompass the
diameter of the tether post 410, yet are narrower than the diameter
of the anchor head 414. Pressing on the button 230 forces the first
push block 234 against the second push block 275 on the slider 278.
This pushes the slider assembly 270 upward, that is, in the
direction against the second biasing spring 272. In so doing, the
cam edges 276 of the slider body 278 push against the push surfaces
246 on the prongs 240, which forces them to move in a lateral
direction indicated by directional arrow A2, that is, away from the
center and toward the sides of the catch device 200. This
effectively widens the area between the prong recesses 240A, so
that the anchor head 414 on the tether post 410 can escape the
catch 260. The leaf spring 274 has an upward bias, up toward the
upper housing 310, and serves as an ejection spring. When the
prongs 240 are opened, so as to release the anchor head 414, the
ejection spring 274 pushes the anchor head 414 upward and out of
the catch 260.
[0046] To capture the tether 400 in the catch device 200, the user
need only insert the anchor head 414 in the post aperture 336 and
push slightly. The anchor head 414 and the edges of the recess 240A
on the prongs 240 are contoured such, that the downward force on
the prongs 240 forces them apart. The anchor head pushes past the
opening formed by the recesses. The prongs 240, being spring biased
toward the center of the device, snap to their catch position, in
which the anchor head 414 is held in the catch device 200 by the
prongs 240.
[0047] It is understood that the embodiments described herein are
merely illustrative of the present invention. Variations in the
construction of the catch device and phone holster may be
contemplated by one skilled in the art without limiting the
intended scope of the invention herein disclosed and as defined by
the following claims.
