of the bottom of the expandable air bag 3 is provided with an annular fastening groove 31, the bottom shell 11 is provided with a round hole 14, and the fastening groove 31 is fastened to the bottom shell 11 via the round hole 14. (The fastening groove 31 can be rotated in the round hole 14, so that the angle of the mobile phone can be conveniently adjusted when the mobile phone is clamped). As the com­bination of the size of the bottom of the fastening groove 31 and the magnet outer base 1 is utilized, fingers can be utilized to hold the portion between the bottom of the air bag 3 and the magnet outer base 1, consequently, the magnet holder is held by the fingers, and when the magnet holder and the mobile phone are combined, the mobile phone can be conveniently fixed and moved; and by the combination of the fastening groove 31 and the round hole 14, the connec­tion between the expandable air bag 3 and the magnet outer base is realized.

FIG. 7 illustrates a closed magnet holder. In order to have a good experience when holding the magnet holder by the fingers, the exterior edges of both the lower shell 11 and inner base 2 of the present embodiment are shaped like circular arcs to define a gap where a user's fingers can grip and expand the magnet holder. By utilizing the circular arc-shaped structures of the bottom shell 11 and the inner base 2, the fingers can be prevented from being scratched when holding the magnet holder, so that the safety of the user is guaranteed, and practicability and experience are enhanced.

In order to affix the expandable air bag 3 onto the inner base 2, the upper portion of the expandable air bag 3 of the exemplary embodiment is provided with an annular fasten­ing ring 32, the inner base 2 comprises a collar 21 hooping the outside of the fastening ring 32 and a top cover 22 nested inside the collar 32 and used for fixing the fastening ring 32 to the collar 21. A friction fit between the top cover 22 and the collar 21 can be utilized to fix the fastening ring 32, thus affixing the expandable air bag 3 and the inner base together.

In order to conveniently fix the expandable air bag 3 and the inner base 2, preferably, the inner wall of the collar 21 of the present embodiment is provided with a plurality of L-shaped limit slots 23, the top ends of the limit slots 23 communicate with the inner surface of the collar 21, a plurality of fastening projections 24 which are aligned with the limit slots 23 are formed on the circumferential wall of the top cover 22, the fastening ring 32 is provided with a plurality of fastening holes 33 which are aligned with the fastening projections 24, and after passing through the fastening holes 33, the fastening projections 24 are fixed in the limit slots 23. Thus, after the fastening projections 24 pass through the fastening holes 33, the fastening projec­tions 24 are pressed into the limit slots 23 from the inner ends of the limit slots 23, and then, by rotating the top cover 22, the expandable air bag 3 and the inner base 2 can be affixed.

In order to ensure the expanding and contraction of the expandable air bag 3, the expandable air bag 3 of the present embodiment is provided with air holes 34. The arrangement of the air holes 34 ensures that air can get into and out of the expandable air bag 3 in the process of contraction and expanding. Applicant's exemplary devices can have various numbers of airholes, e.g., 6 airholes, depending on the applications, material thicknesses, structural rigidity and response times needed.

herein and still achieve Applicant's intended purpose.
Therefore, such disclose fastening methods should not be
construed as limited.
Applicant's airbag at a minimum has a contracted position
(FIG. 7) and an expanded position (FIG. 8). FIG. 8 illustrates
how the magnet holder expands into an expanded position
along a first axis 10. It can also have a half-expanded
position that is similar to the expanded position along the
first axis 10 but does not extend as far. It can also have a
pivot position where the device can be used to support a
mobile device at a surface at a transverse angle to the mobile
device. The pivot position is not fully expanded along the
first axis 10. For example, the pivot position can hold a
mobile phone in a good position on a countertop for viewing
a movie so that the user does not have to hold the mobile
device. Additionally or alternatively, if the magnet holder is
magnetically mounted on a metal surface, the pivot position
can hold the mobile device in a position that is not parallel
to the metal surface.
In order to conveniently affix the magnet holder onto the
mobile phone, a double-sided adhesive tape (not shown) or
a magnet (not shown) can be arranged on the inner base 2 of
the present embodiment. 3MTM 300LSETM is an example
adhesive that could be used.
The expandable airbag can be made of soft materials that
preferably mold easily. For example, Applicant uses thermoplastic polyurethanes for the expandable air bag. Similar
performing materials could be used.
Disclosed throughout this specification are the creation
and connections of components that individually or in 30
combination can comprising methods of manufacturing in
various forms to put together the inner base, the magnet
outer base and the air bag. For example, each fastening
means disclosed herein can be construed as a method step of
performing the step of fastening.
The hard components can be a variety of materials.
Applicant prefers materials that mold easily and are economical and a good tradeoff between strength and weight.
For example, polycarbonate or ABS plastics can be used for
the inner base and the outer magnet base (excluding the
magnet inserts themselves). Similar performing materials
could be used.
In order to conveniently affix and mount the magnet insert
13, an attaching layer 15 is arranged on the bottom of the
lower shell 11 of the present embodiment, the bottom shell 45
11 is provided with a through hole 16 along a vertical
direction, and the magnet insert 13 is arranged in the through
hole, with the bottom attached to the attaching layer 15. By
utilizing the through hole to mount the magnet insert 13 and
the attaching layer 15 to cover the lower ends of the magnet 50
insert, the magnet insert 13 is further fixed; and the attaching
layer 15 may be arranged as a double-sided adhesive tape to
further ensure the affixing of the bottom shell 11.
Magnet insert 13 can be a plurality of magnet inserts. For
example, four 11 mm diameter N50 neodymium magnet 55
discs can be used as shown in FIG. 11. FIG. 12 illustrates
how the plurality of magnet inserts 13 are arranged with
alternating polarities in a molded part around the opening
connecting with the expandable air bag. This configuration
of magnet inserts next to a metal plate helps to build a strong
60magnet within a slender profile magnet outer base. Other
numbers or shapes or sizes or thicknesses or materials of
magnet inserts can be used, depending on the applications.
In one exemplary embodiment, the metal plate is disposed
inside and supported by a circumferential lip 18 extending 65
from the interior of the outer magnet base. Additionally, this
lip 18 can support an exterior portion of each of the plurality

8 
of magnet inserts that is unsupported by the metal plate. This
lip 18 can be molded into the plastic parts, as can the magnet
insert receiving areas to create a strong part with immobile
interior components and strong magnetic force. The circum-
5 ferential lip 18 and the magnet insert holes can be molded as
part of the lower shell of the magnetic outer base, as shown
in the device 5 of FIGS. 9 and 10.
FIG. 13 illustrates the magnet holder mounting a phone to
a front metal panel of a refrigerator. Instead of a refrigerator,
10 a user can magnetically mount the phone wherever it makes
sense, such as a metal toolbox, a metal dishwasher panel, a
car panel, a metal chalk board or wherever else the user may
be working that day. The convenience of Applicant's magnet
holder allows a variety of uses that any related art does not.
15 Although not shown, internal components can contain
glue or other fasteners for the purpose of adhering them
together and creating a robust device.
Applicant can also include an additional metal piece
containing adhesive or a magnet-mountable car interior
20 mount in a kit. Additionally or alternatively, the kit could
contain a phone or a phone case or other phone accessories.
Although the present disclosure has described various
embodiments and examples, it will be understood by those
skilled in the art that the present disclosure extends beyond
25 the specifically disclosed embodiments to other alternative
embodiments and/or uses of the present disclosure and
obvious modifications and equivalents thereof. Additionally,
the skilled artisan will recognize that any of the above-
described methods can be carried out using any appropriate
apparatus. Any equivalent structure or equivalent process
variation made by utilizing the contents of the description
and drawings or direct or indirect application in other related
technical fields shall be included within the scope of claims
