Description
FIELD OF THE INVENTION
[0001] The present invention relates to an auxiliary support rack
and particularly to an auxiliary support rack for a portable
electronic device attachable to a human body to facilitate
one-finger operation without griping the handset with another
palm.
BACKGROUND OF THE INVENTION
[0002] With development of mobile technology portable electronic
devices now have been widely used in people's daily life. However,
used for a prolonged period of time user's hand muscles are easily
fatigued. This is an issue yet to be resolved.
SUMMARY OF THE INVENTION
[0003] The present invention aims to provide an auxiliary support
rack for portable electronic devices that is attached to the front
side of the torso of a human body. It includes an openable dock, a
clamp swivel assembly and a lanyard. The openable dock includes a
first plate which has an installation portion and a second plate.
The clamp swivel assembly includes a rotary tray coupled with the
installation portion and swivelable against the first plate, a gear
set installed on the rotary tray, two clamp members engaged with
the gear set to be moved, therewith to clamp the a portable
electronic device and a latch release member engaged with the gear
set to restrict and release rotation of the gear set. The lanyard
includes two anchor ends fastened to the openable dock and a neck
dangling section hung on a human neck.
[0004] In one embodiment of the invention the first plate includes
a first latch portion corresponding to a first hinge portion, the
second plate includes a second latch portion, set corresponding to
a second hinge portion, to latch with the first latch portion.
Moreover, the first plate includes two lanyard anchor portions
faced the second plate and spaced from each other to anchor the
lanyard. The first plate includes two lanyard directing portions
faced the second plate and spaced from each other to direct the
lanyard. In addition, the second plate includes two anti-skid
members in contact with the front side of the human torso. The
installation portion includes a plurality of positioning struts
jutting toward the rotary tray, and the rotary tray includes a
plurality of positioning indentations corresponding to the
positioning struts for latching therewith. The second plate further
includes a storage portion faced the first plate to hold a
plate-shaped object, and also includes an anchor portion jutting
toward the first plate to press the plate-shaped object. The latch
release member includes a jutting teeth portion to engage with the
gear set, a push portion jutting through the rotary tray and
depressible by users, and an elastic press portion to provide an
elastic press force to keep the jutting teeth portion to maintain
the engaged condition with the gear set. Furthermore, each clamp
member includes a gear rack engaged with the gear set and an
elastic butting portion connected to the rotary tray to provide an
elastic butting force. Through the structure set forth above sore

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] Please referring to FIGS. 1, 2 and 3, the present invention
aims to provide an auxiliary support rack for portable electronic
devices that can be hung on the neck of a human body and attached
to the front side of the human torso. The auxiliary support rack
comprises an openable dock 1, a clamp swivel assembly 2 and a
lanyard 3. The openable dock 1 includes a first plate 11 and a
second plate 12 hinged on the first plate 11. The first plate 11
includes a first hinge portion 111, a first latch portion 112
corresponding to the first hinge portion 111, an installation
portion 113 faced another side of the second plate 12, two lanyard
anchor portions 114 faced the second plate 12 and Spaced from each
other to anchor the lanyard 3, and two lanyard directing portions
115 faced the second plate 12 and spaced from each other to direct
the lanyard 3. The installation portion 113 includes a plurality of
positioning struts 116 jutting toward the clamp swivel assembly 2.
The second plate 12 includes a second hinge portion 121 hinged on
the first hinge portion 111, a second latch portion 122
corresponding to the second hinge portion 121 and latchable with
the first latch portion 112, a storage portion 123 faced the first
plate 11, an anchor portion 124 jutting toward the first plate 11
and two anti-skid members 125 located at the bottom side of the
second plate 12. The anti-skid members 125 can be in contact with
the front side of the human torso to provide a friction force.
[0012] In addition, the clamp swivel assembly 2 includes a rotary
tray 21 coupled with the installation portion 113, a gear set 22
coupled with the rotary tray 21, two clamp members 23 engaged with
the gear set 22 to be moved therewith, and a latch release members
24 engaged with the gear set 22 to restrict and release rotation of
the gear set 22 to adjust the relative distance of the two clamp
members 23. The rotary tray 21 includes a plurality of positioning
indentations 211 corresponding to the positioning struts 116 to
form latching therewith. The latch release member 24 includes a
jutting teeth portion 241 engaged with the gear set 22, a push
portion 242 jutting through the rotary tray 21 and depressible by
users to move the latch release member 24, and an elastic press
portion 243 to provide an elastic press force to keep the jutting
teeth portion 241 and the gear set 22 in the engaged condition. The
gear set 22 includes three gears, in which the middle gear has two
rows of wheel gears abreast with each other. One row of the wheel
gears is engaged with other two gears, while other row of the wheel
gears is collaborated with the jutting teeth portion 241 to form a
ratchet gear function. Each clamp member 23 includes a gear rack
231 engaged with the gear set 22 and an elastic butting portion 232
connected to the rotary tray 21. The lanyard 3 includes two anchor
ends 31 connected to the openable dock 1 and inserted into the two
lanyard anchor portions 114 for anchoring, and a neck dangling
section 32 located between the two anchor ends 31 to be hung on the
neck of the human body.
[0013] Please referring to FIGS. 4A and 4B, when in use, a user
flips the first plate 11 or the second plate 12 open, and the first
plate 11 and the second plate 12 swivel about the first hinge
portion 111 and the second hinge portion 121 as a hinge center,
meanwhile the first latch portion 112 and the second latch portion
122 are latched with each other at varying flipped angles to form
positioning against each other. Next, the user can swivel the
rotary tray 21 against the first plate 11 about the installation
portion 113 as a swivel center such that the positioning
indentations 211 can be latched with the positioning struts 116,
then the rotary tray 21 and the first plate 11 can be positioned
against each other at different swivel angles.
[0014] Furthermore, the elastic butting portion 232 can push the
two clamp members 23 outward through an elastic butting force, and
the elastic press portion 243 keeps the jutting teeth portion 241
and the gear set 243 in the engaged condition through an elastic
press force. When the user wants to install the portable electronic
device on the auxiliary rack, the user needs merely placing the
portable electronic device between the two clamp members 23 and
moving toward the two clamp members 23 to form clamping thereof.
Meanwhile, the gear set 22 is driven by the gear racks 231 and
moves. When the two clamp members 23 are moved close to the
portable electronic device and stop the movement the gear set 22
also stops movement. Then the jutting teeth portion 241 is engaged
with the middle gear to form a ratchet gear function to keep the
two clamp members 23 at a distance matching the portable electronic
device without being pushed outward by the elastic butting force of
the elastic butting portion 232, therefore can clamp the portable
electronic device. When the user wants to remove the portable
electronic device from the auxiliary support rack the user needs
merely to push the push portion 242 to overcome the elastic press
force of the elastic press portion 243, then the jutting teeth
portion 241 escapes the middle gear of the gear set 22, and the two
clamp members 23 are pushed outward by the elastic butting force of
the elastic butting portion 232 and return to their original
positions. The storage portion 123 can hold a plate-shaped object.
The anchor portion 124 can push the plate-shaped object while it is
held in the storage portion 123. The two lanyard directing portions
115 can direct the lanyard 3 in a direction remote from the
portable electronic device.
