7 Claims. (Cl. 248—349)
This invention relates to a theft-proof television swivel
and more particularly to a swivel mounting for television
receivers, or the like, of such construction as to prevent
an unauthorized removal.
Heretofore, and this is particularly true in motels and
in some hotels, smaller sized television sets are so at
nut 18, which abuts the outer end portion of the sieeve 16
and is also ?xedly secured thereto in any suitable fashion
such as by the Welds 20.
At the same time the nut 18 loosely engages the under
surface of the base plate 11 so that in effect the said base
plate 11 is loosely mounted as indicated at 21 with re
spect to the swivel assembly, including the sleeve 16, disc
14 and the nut 18.
A series of equally spaced radial notches 22 are formed
in the peripheral edge of the nut 18 for cooperative regis
try with the projection 34 at the end of the arm 32 of
the spanner wrench 31, whose inner curvature as at 33
substantially corresponds to the outer curvature of the
nut 18 for operation in a manner hereafter described.
A series of bores 23 are formed partly through the
tractive that they are oftentimes carried off by the guests. 15
The primary object of the present invention is to pro

By this construction it is apparent that in view of the
limited and reduced height for the disc-like nut 13, the
base plate 11 is so close to the support 26 as to positively
preclude manual application or access to the fasteners

television receiver from its swivel mounting or from the
support 26 of the furniture. The only means by which
this can be achieved is the application of a special type
of spanner wrench, such as is shown in FIG. 3, normally
