Universal connector for remote
control vehicles
Abstract
A connector for use with a remote controlled apparatus comprising a base adapted to receive a control member and a contact surface adapted to slidingly receive a latch. Two fingers extend outwardly from the base and the latch has opposingly located deformable prongs which engage a pin and two arms which engage a contact surface found on the base. The latch is slidingly operable on the contact surface of the base between a locked and an unlocked position. In the locked position, the fingers of the base and the pin form a closed, unopenable structure. In the unlocked position, the fingers and the pin form an openable structure.

Description
BACKGROUND OF THE INVENTION
The present invention relates to a universal connector that is
used to link various components of a remote controlled vehicle
such as hobby aircraft together. More specifically, the present
invention concerns a U-shaped connector that includes a self-contained
latch which coacts with a pin.
SUMMARY OF THE INVENTION
In remote control aircraft, as well as other hobby vehicles, a
number of moving parts need to be linked together in order to
operate the device. To do this, connectors are often used which
link moving parts such as a servo arm to the control horn of a
flap.
However, by design, the parts of a remote control vehicle are
often reduced in size, and as a result, the components are often
difficult to manually manipulate and are difficult to keep from
losing. This is especially true with respect to retaining pins
and locking clips.
The present invention is designed to provide a more user friendly
connector in which the latch or locking clip forms part of the
connector. This makes the device easier to use and reduces
incidence of losing the small sized clips during use.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Set forth below is a description of what are currently believed
to be the preferred embodiments or best examples of the invention
claimed. Future and present alternatives and modifications to the
preferred embodiments are contemplated. Any alternates or
modifications in which insubstantial changes in function, in
purpose, in structure or in result are intended to be covered by
the claims of this patent.
As shown in FIGS. 1 and 2, the present invention includes a base
10, which includes an aperture 12 which is sized to receive a
control rod (not shown). Typically, the control rod is self-tapping,
and thus, locks into position within aperture 12.
Extending outwardly from base 10 are fingers 14 and 16. As shown
in FIG. 3 channel 18 is formed in finger 16 by L-shaped walls 20
and 22. Of course, channel 18 may be located on finger 14 as well.
Since base 10 may be made of plastic, its components may be
simply created as a single molded unit. However, as shown in FIG.
4, angled or radius portions 202A and 202B may be added to the
juncture where the fingers joint the base. Increasing the
material or mass used in this location reduces unwanted breakage
during the use of the fingers.
Located within channel 18 is a latch 24 having a handle 26. Latch
24 also includes a slit 28 and aperture 30 which separates
opposingly located prongs 32 and 34. As shown in FIG. 1, latch 24
is also operable between a locked and unlocked position. Latch 24
may also include on it imprinted identification 203 which
identifies the size of the control rod which would fit within
aperture 30.
Located on fingers 14 and 16 are apertures 40 and 42. The
apertures are aligned so that pin 50 may be inserted into the
apertures. As is also shown in FIG. 2, the diameter of the
aperture located on finger 14 is larger than the aperture located
on finger 16.
As shown in FIG. 2, pin 50 includes a head 52, a first portion 54
which is sized to fit within aperture 42. Also included is an
internal stop 56 and second portion 58 which is sized to fit
within aperture 40. Pin 50 also has a terminal end 62 which
includes an annular groove 60.
In use, the aircraft piece to be connected is inserted between
fingers 14 and 16 so that pin 50 may be inserted through an
aperture in the aircraft component. To do this pin 50 is inserted
into apertures 40 and 42. As shown in FIG. 2, head 52 engages
wall 51 of finger 14 and acts as a stop when pin 50 is fully
inserted.
Internal stop 56 is also positioned to engage inner surface or
wall 53 of finger 16. This engagement assists in properly
aligning groove 60 by causing lower edge 63 of groove 60 to be
flush with wall 55 of finger 16.
Once groove 60 is properly positioned, latch 24 may be slidingly
moved from an unlocked position into a locked position. When
operated to secure pin 50, the first portion to engage pin 50 is
V-shaped notch 61. As latch 24 is pressed against pin 50, the
engagement forces prongs 32 and 34 to spread apart so that pin 50
may be received by aperture 30. Slit 28 permits this spreading or
deformation to occur. Once aperture 30 is positioned around
groove 60 of pin 50, prongs 32 and 34 snap inwardly resulting in
the upper and lower surfaces 70 and 71, respectively, to seat
within groove 60. This engagement prevents pin 50 from
disengaging latch 24 which locks the pin into position. To unlock
this pin, the opposite steps are used.
Latch 24 is also frictionally fitted within channel 18 and
slidingly engaged by walls 20 and 22. This arrangement permits
latch 24 to articulate within channel 18 while still being
secured to base 10. This makes the latch easier to use and
reduces the incidence of losing a free-standing clip or latch.
Also making the device easier to use are the two different sized
apertures in the fingers and two stops, 52 and 56, on the pin.
This arrangement acts to consistently place the groove in a
proper alignment so as to receive latch 24. Again, when dealing
with small parts, this ability to achieve proper alignment makes
the device easier to operate. Thus, not only may the present
invention be beneficially used with remote-controlled aircraft,
the invention is also useful with other hobby type vehicles such
as cars, boats, sailboats, and helicopters as well.
Another way to make the device is to employ latch 124 as shown in
FIGS. 6-10. In this embodiment, base 100 includes rounded distal
end portion 102, which defines a contact surface that is adapted
to receive control rod 103. Base 100 also includes opposingly
located arms 200 and 201 and pin 205 as shown in FIGS. 6 and 11.
Pin 205 is stepped in configuration and may be permanently
mounted to one of arms 200 or 201. In the embodiment shown, pin
205 is mounted to arm 201 and arm 200 includes an aperture 210
which receives pin 205.
Arm 200 is movable so that it may be lifted off of pin 205 to
allow pin 205 to be placed inside an object to be connected. The
arm and pin arrangement forms a clip-like structure which is
designed to releasably engage other objects. In a locked
position, the clip-like structure cannot be opened. In an
unlocked position, the clip-like structure may be opened by
lifting one of the arms off of the pin.
Latch 124 is of a similar design as described above but includes
two opposingly located curved arms 130 and 131. Each arm extends
inwardly and together form a circular-like arc which is about 320
degrees. That the arms do not form a complete circle leaves
aperture 105. As will be described in more detail below, this
arrangement allows latch 124 to engage rod 103.
In operation, latch 124 is affixed by locating rod 103 in
aperture 105. Next latch 124 is mounted to base 100 by sliding it
into engagement with portion 102 as shown in FIG. 7 through the
use of handle 158. Because the inner contact surface 150 defined
by arms 130, 131 and latch 124 forms a shape which releasably
mates with the shape of distal portion 102 of base 100, the latch
is held in place on the device and able to engage pin 133. Once
pin 133 is engaged, the arm and pin engagement is locked in place
and the resulting clip cannot be opened. While circular shapes
are shown, other contact surfaces having shapes which would
produce a snug or friction fit would be equally suitable. By
configuring the latch and base in this manner, the incidence of
losing the latch during use is reduced.
While the preferred embodiments of the present invention have
been illustrated and described, it will be understood by those of
ordinary skill in the art that changes and other modifications
can be made without departing from the invention in its broader
aspects. Various features of the present invention are set forth
in the following claims.
