(01. 155-53625) .
The invention aims to provide a novel bathtub
attachment embodying both a seat to overlie the
tub side wall, and a grab rail to assist when
entering and leaving the tub.
6 ;
In carrying out the above end, a further object
is to provide a simple and inexpensive, yet an
ef?cient and reliable clamping means for e?ec
tively clamping the attachment to the tub side
wall.
10: Another object is to provide unique means for
rotatably mounting the seat if desired.
With the foregoing in view, the invention re
sides in the novel subject matter hereinafter de
scribed and claimed, description being accom
l?iplished by reference to the accompanying .draw
clamps I2, said ends of said grab rail being pref-'
erably extended laterally in the same direction as
shown at I8 and integrally joined to said legs
I6. The crown portions I5 of the two clamps |2
are preferably provided with rubber buttons or
the like I9 to rest on the tub rim, and the outer
tons 20 to abut the outer side of the usual double
walled tub. The legs I6 of theclamp members .1

the clamp member 2 I, the clamp I2 may be tightly
engaged with the tub side wall. Then by tighten- j
ing the nut 26, the ?anges 23 are inwardly moved
into tight frictional engagement with the leg I6
to hold said clamp- member in operative position.
If desired, a screw 29 may be carried by the clamp
member 2| to abut the lower end of the leg I6
for forcibly sliding said member 2| downwardly.
In the present showing, the screw 29 is threaded 45
upwardly through a bottom flange 3|] which ex

may either be of ?xed or non-rotatable type.
To facilitate lifting and release of the clamp
Each clamp I2 comprises a crown portion I5 to
extend over the tub side wall, an inner vertically
elongated leg I6 rigidly joined to one end of the
55 crown portion I5, and an outer vertically elon
member 2| when the attachment is to be removed
from the tub, I have shown a handle 32 on one
of the ?anges 23 but the use of such a handle is,
of course, optional.

In Figs. 6 and 7, two clamps l28L support a
stationary or rotatable seat I4a and the inner
legs l6st of these clamps are integrally connected
by means of a grab rail 13*‘. The outer legs I'Ia
6 of the clamps lla are each provided with‘ an inte
gral horizontal extension 33 to underlie the rolled
rim 34 of an older type of bathtub, said exten
sion 33 having an upstanding lug or the like 35
which assists in providing a seat 36 for the lower
10
edge of said rim. :Ahorizontally swingable arm,
novel and advantageous provision has been made
for carrying out the objects of the invention, and
while preferred details have been disclosed, vari
ations may of course be made within the scope
of the invention as claimed.
