PORTABLE KEY ASSEMBLY
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
The present invention generally relates to an apparatus used to open a lock. More
particularly, the present invention relates to a portable key and method of its use.
i o DESCRIPTION OF PRIOR ART
A key is a frequently used article in daily life. Generally, a key comprises a key body
and a key handle. The key body is used to lock and unlock a lock. The width of the key
handle is typically greater in magnitude than the width of the key body. Thus, the key
15 handle functions, in part, to increase the turning torque of the key body during unlocking
movement. The key handle may further function to provide certain convenient carrying
means as may be taught or defined by certain key accessories such as a key ring, a key chain,
or a key case as connected or coupled to the key handle by way of a punched hole on the key
handle. A disadvantage of the enlarged key handle is that the enlarged key handle
0 simultaneously expands the volume of the key thereby occupying a relatively larger space
and often results in a key bunch that is out of order, and/or inconvenient to carry after
connecting with other key accessories.
The prior art thus perceives a need for a key assembly having locking/unlocking key
structure with otherwise bulky handle structure removed. A key having an abbreviated
handle may thus function to occupy a relatively smaller space and provide for or enable a
relatively compact and tidy key bunch and/or key-carrying means
SUMMARY OF THE INVENTION
It is thus an object of the present invention to overcome the above-mentioned
shortcomings, in part, by reducing the volume of a single key and thus enabling compact key
bunch storage and transport. For example, when the key is connected with or coupled to
other key accessories, the resulting assemblage may provide a convenient-to-carry and
easy-to-use set of keys.
The invention thus essentially provides a key body comprising a lock fastener set at one
end of the abbreviated key handle of the key body. It is contemplated that the lock fastener
may be defined by an elastic snap fastener set on the abbreviated key handle. It is further
contemplated that when used in combination with other keys of the same sort, the resulting
key set may be carried with certain key-carrying means having certain cooperative lock
fastening means. Certain key carrying accessories may be defined by a plate key card, a
flexible key strap, an elastic key clip and any number of key cases.
The method of using the key contemplated by the present invention is contemplated to
comprise the steps of connecting and/or fastening the key via certain lock fastening means
incorporated into the construction of key itself or certain key accessories for the convenience
of using and carrying.
A further usage may be defined by methodology after connecting the key with other keys
or key accessories. In this regard, it is contemplated that the post-connect methodology may
be defined by turning the key utilizing the connected keys and or key accessories as torque
arms, thereby enhancing or easing unlocking movement of the key.
Thus, this portable key can be connected and overlapped in face-to-face or side-by-side
adjacency with other keys or key accessories so that they are compactly combined, not easily
lost, and convenient to carry, hi addition, with the moment arm extension formed by
connecting this portable key with other keys or key accessories, the turning torque of the key
handle is enlarged so that the portable key can function properly even if the key handle is
shortened and the volume of the whole key is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
Referring now to the drawings, the preferred embodiment of the present invention
generally concerns a key Al as illustrated and referenced in Figure Nos. 1 - 3 and 7 - 9. In
a first implementation as illustrated or depicted in Figure No. 1, key Al comprises an elastic
snap fasteners 1 fixed on the flake key handle 2 at one end of the key body 3. Preferably,
the elastic snap fasteners 1 may comprise cooperative male and female mating structure,
which are convenient to connect and fasten with other portable keys A2 and key accessories
outfitted with cooperable elastic snap fastener(s) 1. Other portable keys A2 cooperable with
key Al are illustrated and referenced in Figure Nos. 2, 7, and 8. From an inspection of the
noted figures, it will be seen that the width of the abbreviated key handle 2 is approximate to
that of the key body 3. As compared to state of the art keys of the general sort, it should be
understood that the width and length of the key handle 2 is greatly reduced.
In a second implementation of the present invention as generally depicted in Figure No. 2,
several portable keys Al and A2 may be connected or overlapped together for the
convenience of using or carrying the same. The portable keys Al and A2 maybe connected
via the lock fastener 1 on the flake key ring or key handle. It is contemplated that an
alternative lock fastener 1 of the present invention may comprise a magnetic member, via
which, several portable keys may be connected or overlapped in face-to-face or side-by-side
relation so as to form a compact integration, for the convenience of using or carrying.
It is contemplated that when using a certain key Al to unlock a lock, key Al may be
turned with the key body 3 separated from the key bodies 3 of other keys A2 to a certain
angle, and the key Al may then be inserted into the lock. To key body 3 of key Al , other
keys A2 may be connected, which keys A2 then become moment or torque arm extension(s)
of the key handle 2 of key Al . When key Al is turned, its moment torque can thus be
enlarged or increased by way of keys A2, making the unlocking and locking more
convenient.
In a third implementation as illustrated and referenced in Figure No. 3, the portable key
Al may be connected and fastened with the lock fastener 5 fixed on a plate key card 4 in
face-to-face relation to use or carry together. Key plate 4 is preferably rectangular, with a
line of lock fasteners 5 fixed on opposite edges of the portable key, which may effectively
function to connect a key Al or keys Al with the corresponding lock fasteners 5 for the
purpose of using and carrying. When wanting to turn a selected key Al (i.e. for example,
when unlocking a lock), one need only turn or pivot the key body 3 of the portable key Al to
the outside of the key plate 4 as generally depicted in Figure No. 3 at 10. Once pivoted to
such an orientation, the key plate 4 may thus function as a moment or torque arm extension of
the key handle 3, thereby enlarging the moment torque of the selected portable key Al . The
lock fastener 1 on this portable key Al and the lock fastener 5 on the key plate 4 may be
cooperable female and male snap fasteners.
In a fourth implementation of the present invention, as generally depicted in Figure No. 4,
key Al may be connected and/or fastened with the lock fastener(s) 5 on either end of the
flexible key strap 6 in face-to-face relation for the purpose of using and carrying. When so
coupled or connected, the flexible key strap 6 may be used to hang and carry the keys Al.
When the user is desirous of utilizing the key for unlocking and/or locking operations, the
user may turn or pivot the portable key Al so that a certain angle extends intermediate the
key strap 6 and the key body 3 of the key Al . Thus, the key strap 6 may be used as a
moment or torque arm extension of the key handle 2 of the portable key Al, enlarging the
moment torque of the portable key.
In a fifth implementation of the present invention as generally depicted in Figure No. 5, it
is contemplated that the key Al may be connected and/or fastened to either of certain lock
fastener(s) 5 formed on both ends of a V-shaped elastic key clip 7 in face-to-face relation for
the purpose of using or carrying. It is contemplated that the elastic key clip 7 may be
clamped on a carrying object. When the user is desirous of utilizing the key for unlocking
and/or locking operations, the user may turn or pivot the portable key Al so that a certain
aEngle extends intermediate the key clip 7 and the key body 3 of the key Al . The elastic clip
7 may then be used as the moment or torque arm extension of the key handle 2 of the portable
key Al thereby enlarging the moment torque of the key Al.
In a sixth implementation of the present invention as generally depicted in Figure No. 6,
it is contemplated that a key Al or keys Al may be connected and/or fastened via the key
handle(s) 2 with lock fastener (s) 5 on a first key case 8 in face-to-face relation. The key
case 8 is connected with lock fastener(s) 5 on a fastener strap 9 via its lock fastener 5. Via
the fastener strap 9, the key case 8 may be attached to the human body, such as around a
user's wrist (in much the same manner as a wristwatch). When the user is desirous of
utilizing the key Al for unlocking and/or locking operations, the user may turn or pivot the
portable key Al so that a certain angle extends intermediate the longitudinal axis of the key
case 8 and the key body 3 of the key Al . The key case 8 may thus be used as the moment or
torque arm extension of the portable key Al for enlarging or increasing the moment torque of
the portable key Al .
In a seventh implementation of the present invention as generally depicted in Figure No.
7, it is contemplated that a key Al and/or key A2 may be connected and/or fastened to a tie
clip type structure 11, which tie clip structure 11 may then be simultaneously worn as a tie
clip and function as a key-carrying device or assembly. It is contemplated that the tie clip
structure 11 may be connected to a key Al or key A2 with certain lock fastener(s). Via the
tie clip structure 11, the key Al or A2 may be attached in adjacency to a human body, such as
at or around a user's tie. When the user is desirous of utilizing the selected key for
unlocking and/or locking operations, the user may turn or pivot the portable key so that a
certain angle extends intermediate the longitudinal axis of the tie clip structure 11 and the key
body 3 of the key Al or key A2. The tie clip structure 11 may thus be used as the moment
or torque arm extension of the portable key Al or key A2 for enlarging or increasing the
moment torque of the selected portable key.
In an eighth implementation of the present invention as generally depicted in Figure No.
8, it is contemplated that a key Al and/or key A2 may be connected and/or fastened to a
pocket clip type structure 12, which pocket clip structure 12 may then be simultaneously
worn as a pocket clip and function as a key-carrying device or assembly. It is contemplated
that the pocket clip structure 12 may be connected to a key Al or key A2 with certain lock
fastener(s). Via the pocket clip structure 12, the key Al or A2 may be attached in adjacency
to a human body, such as at or around a user's shirt pocket. When the user is desirous of
utilizing the selected key for unlocking and/or locking operations, the user may turn or pivot
the portable key so that a certain angle extends intermediate the longitudinal axis of the
pocket clip structure 12 and the key body 3 of the key Al or key A2. The pocket clip
structure 12 may thus be used as the moment or torque arm extension of the portable key Al
or key A2 for enlarging or increasing the moment torque of the selected portable key.
In a ninth implementation of the present invention as generally depicted in Figure No. 9,
it is contemplated that a number of keys Al may be connected and/or fastened to a second
key case 13 (akin to a business card carrying case), which key case 13 may be used to house
and carry keys Al as generally depicted. It is contemplated that the key case 13 may be
connected to a plurality of keys Al with certain lock fastener(s). When the user is desirous
of utilizing the selected key for unlocking and/or locking operations, the user may turn or
pivot the portable key so that a certain angle extends intermediate the key case 13 and the key
body 3 of the selected key Al . The key case 13 may thus be used as the moment or torque
arm extension of the portable keys Al for enlarging or increasing the moment torque of the
selected portable key.
Other types of proprietary key-carrying devices are contemplated that do not necessarily
function as a moment or torque arm extension, but instead function to simply and
conveniently store or house a plurality of keys Al . Li this regard, it is contemplated that
certain key-housing means usable in combination with a key or keys Al may be defined by a
third key-carrying case or key pouch 14 as generally depicted in Figure No. 10; a fourth
key-carrying case or wrist-mountable case 15 as generally depicted in Figure No. 11; or a
fifth key-carrying case or billfold type case 16 as generally depicted in Figure No. 12.
While the above description contains much specificity, this specificity should not be
construed as limitations on the scope of the invention, but rather as an exemplification of the
invention. For example, it is contemplated that the essence of the present invention teaches
a portable key assembly (such as key Al) comprising a primary key body (such as key body
3), a primary key-borne lock fastener (such as lock fastener 1), and a primary, two-sided,
abbreviated key handle (such as key handle 2). The lock fastener is essentially set on the
key handle at one end of the key body.
The portable key assembly is pivotally fastenable to select key-attachment structure (such
as at least one second key assembly or key A2 identical to the first key assembly or key Al or
any number of key accessories). It is contemplated that the select key-attachment structure
functions to provide a torque arm relative to the key body for increasing torque for locking
and/or unlocking key movement. The select key-attachment structure may thus be defined
by at least one second portable key assembly identical to the portable key assembly and
matable thereto via the key-borne lock fasteners, or the select key-attachment structure may
be a select key accessory, in which case the select key accessory is outfitted with an
accessory-borne lock fastener (such as lock fastener 5). The accessory-borne lock fastener
is matable with the key-borne lock fastener for attaching the key assembly to the select key
accessory. The select key accessory may be selected from the group consisting of a key
card (such as key card 4), a key strap (such as a key strap 6), a key clip (such as clip 7, or
structure(s) 11, 12) and a key case (such as cases 8, 13 14, 15, or 16).
The key-borne lock fastener may be defined by an elastic snap fastener or a magnetic
member with opposing matable fastener ends. If the lock fastener is an elastic snap fastener,
the fastener ends are exposed on opposite sides of the two-sided key handle and may be
defined by a male fastener and a female fastener. It should be further understood that the
key handle has a certain handle width and the key body has a certain body width, the handle
width being substantially equal in magnitude to the body width.
Accordingly, although the invention has been described by reference to certain
preferred and alternative embodiments, it is not intended that the novel disclosures herein
presented be limited thereby, but that modifications thereof are intended to be included as
falling within the broad scope and spirit of the foregoing disclosure, the following claims and
the appended drawings.
