Bar antenna holder
Abstract
To a cabinet to which an antenna is desired to be attached,
there is fastened a fixing member which has an arc housing formed
in the front wall and a through aperture at the bottom to admit an
arm plate. Through said through aperture is inserted the arm plate
which is provided at one end thereof with a cylindrical supporting
body. The cylindrical supporting body contains therein a socket
adapted to receive a cylindrical holding member. The cylindrical
holding member through which an antenna is passed and held in
position is set into rotatable engagement with the socket of said
cylindrical supporting body. When the cabinet is to be moved or
packed, the antenna can be stowed in close proximity to the cabinet
by pushing the arm plate through the aperture. When the antenna is
put to use, it is suitably separated from the cabinet by pulling
the arm plate out through the aperture so that it can be turned and
set into a desired direction in which the highest effects of
reception are obtained.

Description
BACKGROUND OF THE INVENTION
This invention relates to an apparatus for holding in position the
bar antenna which is intended for use with receivers such as radio
sets and stereophonic sets.
Heretofore, most bar antennas designed for use with receivers have
generally been fixed stationarily inside the cabinets of such
receivers. With a view to improving the effects of reception,
however, the practice of fastening bar antennas to the outer face
of cabinets in enjoying widespread acceptance.
Various holder systems designed to permit bar antennas to be held
on the outside of cabinets have been proposed and put to use. These
conventional systems are invariably designed for immobilized
fixation and, therefore, have suffered a disadvantage that the
direction of reception becomes fixed. Further because they cannot
be retracted into a safe position, protruding antennas become
obstacles or suffer damage when the systems are to be packed at the
time of conveyance.
In view of the drawbacks mentioned above, the present invention
aims to provide a bar antenna holder system which permits the bar
antenna to be held freely movably relative to the cabinet so that
it may be stowed in a state of intimate contact with the cabinet
proper as when the cabinet is transported, separated away from the
cabinet proper to obtain improved effects of reception at the time
of service and turned and set in any freely selected direction in
which the desired reception is obtained under the most advantageous
conditions without reference to the direction in which the cabinet
is placed.
SUMMARY OF THE INVENTION
To attain the objects described above in accordance with the
present invention, there is provided a bar antenna holder system
which comprises in combination a fixing member composed of an
adapter plate piece and an arc housing formed on the front wall of
said adapter plate piece and incorporating an aperture perforated
at the bottom of said arc housing, a supporting member composed of
an arm plate adapted to be freely inserted in or extracted out
through the aperture of said fixing member and a cylindrical
supporting body provided at one end of said arm plate and adapted
so as to engagingly stowed into said arc housing by having said arm
plate slid in through said aperture and a cylindrical holding
member provided exteriorly with a fastener for rotatable engagment
with the supporting body of said supporting member and interiorly
with a hole adapted to permit a bar antenna to be passed
therethrough and held in position. When the cabinet is to be
removed or packed, the bar antenna can be stowed in close proximity
to the cabinet by having the arm plate slid inward through the
aperture. when the cabinet is to be put to use, the bar antenna can
readily be drawn out of the cabinet by sliding the arm plate out
through the aperture and it then can be turned and set in any
desired direction for the best effects or reception.
With the above and other objects in view which will become apparent
in the following detailed description, the present invention will
be clearly understood in connection with the accompanying
drawing.

DETAILED DISCRIPTION OF THE INVENTION
The illustrated embodiment represents one typical example of the
present invention. The invention will be described herein below by
reference to the drawings, wherein 1 denotes a fixing member
adapted to be fastened directly by means of screws to a cabinet A
such as of a stereophonic receiver and 2 denotes a supporting
member adapted to cause a holding member 3 holding a bar antenna B
in position thereon to be supported freely extractably against said
fixing member.
The fixing member 1, as illustrated, has an adapter plate piece 4
shaped in an angular section to facilitate attachment to the
cabinet A and has an arc housing 5 formed integrally with a front
wall 4a vertically rising from said adapter plate piece. At the
bottom, the fixing member has a through aperture perforated in such
way that the aperture opens in the direction of the opening
including the chord of the arc housing and, at the same time,
pierces rearward along the lower face of the bottom wall 4b of said
adapter plate piece.
The supporting member 2 to be fastened to said fixing member is
composed of an arm plate 7 in the shape of a strip of plate and a
cylindrical supporting body 8 provided at the rear end of said arm
plate. It is to adapted as to be fastened onto the fixing member by
having said arm plate inserted past the opening of said arc housing
5 and through the aperture 6 formed at the bottom of said arc
housing.
In the case of the illustrated embodiment, the arm plate for
insertion through the aperture is provided at the forward end
thereof with a pair of clicks 7', 7' inclined backward and formed
integrally with the plate. When the arm plate is in the process of
going through the aperture, these clicks are so deformed as to
advance and reach the rear side of the aperture. Once the clicks
have gone past the aperture, they serve to prevent the arm plate
from being completely pulled out through the aperture. Thus, said
arm plate is permitted to provide free sliding motion through the
aperture in the range corresponding to the length from the
supporting body 8 and the clicks 7', 7'. Said supporting body 8 is
so shaped that its outside diameter equals the inner diameter of
the arc housing of the fixing member. When said arm plate is slid
inward through the aperture, therefore, the supporting body forces
its way through the opening of the arc housing and snaps into
intimate engagement with the inside of the housing. Therefore, said
supporting member 2 permits the supporting body 8 to be pulled out
away from the fixing member 1, with due guidance afforded by the
arm plate inserted through the aperture. On the other hand, when
the supporting member is pushed in toward the fixing member, the
supporting body 8 is drawn in until it forces its way through the
opening of the arc housing and finally stows itself in engagement
with the housing.
The holding member 3 serving to hold the bar antenna relative to
the supporting member 2 which is attached to the fixing member as
described above has a cylindrical shape. On the outside of said
holding member is planted a fastener 9 which is adapted to permit
engagement with the supporting body 8 of said supporting member.
The fastener 9 thus formed is composed integrally of a base 9a
shaped so as to have a diameter equalling the inside diameter of
the supporting body 8, a shaft 9b having a smaller diameter and
formed protrudingly from the center of said base and a head 9c
formed at the forward end of said shaft. The fastener downwardly
confronts said supporting member. It is fastened to the supporting
member by allowing the head 9c of the fastener to advance past an
annular step 8' formed along the inside of said supporting body and
come into engagement with the farther side of said annular step and
at the same time causing the base 9a of the fastener to come into
snug contact with the opening of the supporting body. Once the
holding member 3 is thus fastened in position, therefore, the head
9c of the fastener which is now in engagement with the annular step
8' prevents the holding member from being readily separated from
engagement and at the same time enables the holding member to be
freely rotated while in a fastened state.
In order for the bar antenna to be held in position on this holding
member, it is required only to be pushed into the cylinder proper
of this member at one end of the opening thereof.
The holder system of the present invention which comprises the
fixing member 1, the supporting member 2 and the holding member 3
as described above is fastened to a given cabinet by placing the
adapter plate piece 4 of said fixing member at a lower corner
portion of the cabinet as shown in FIG. 4 and driving the screws
10, 10 through the bottom wall 4b of said adapter plate piece 4.
Since the supporting member which is engaged with the fixing member
is freely slidably disposed relative to the aperture 6 and
therefore can freely be pulled out away from the fixing member as
explained previously, the holding member 3 fastened to said
supporting body 8 can be pulled out far from said cabinet. Further
since said holding member is freely rotatably supported relative to
the supporting member, there is enjoyed an advantage that the
holding member now in a position separated from the cabinet permits
the bar antenna held thereon to be turned freely and set to a
direction in which the reception is obtained under the best
conditions.
In addition to permitting the supporting member to be pulled out
freely, the apparatus of the present invention enables the
supporting member to be pulled in so that the supporting body 8 of
said supporting member is engagingly stowed within the arc housing
5 of the fixing member and is prevented from being released to move
at random, thus allowing the bar antenna position on the supporting
member to be held in intimate contact with the side wall of the
cabinet. When the cabinet is placed in a packing case at the time
of conveyance, for example, this intimate contact permitted by the
present apparatus proves advantageous because the bar antenna
neither offers obstacle nor sustains damage in transit. The
component members of the present apparatus are formed of a plastic
material and, therefore, enjoy the advantage of low cost and rich
utility.
