The present invention relates to an article for securing
a continuous pipe to a wall or the like, this article comprising a
pipe clamp that encircles the pipe and a carrier that is connected
to the clamp arms of the pipe clamp and is arranged on the wall.
In order to secure a continuous pipe at a specific
distance from a wall, it is known that the pipe can be encircled
by a pipe clamp, a bracket can be secured between the clamp arms
of the pipe clamp by a screw, the bracket then being secured to
the wall by any means desired, if necessary with the incorporation
of a bend. However, an article of this kind entails a
disadvantaye in that the pipe can only be rotated through a
speciflc angular range ln the plane of the bracket that is secured
between the clamp arms of the pipe clamp, whlch is a partlcular
disadvantage when inclined, curved or angled runs of pipe are to
be installed.
It is the alm of the present invention to create an
article of the type descrlbed in the introduction hereto, that
makes lt posslble to rotate the plpe freely about the transverse
a~ls that passes through the carrier, and also ensures rapld
connectlon between the clamp arms of the plpe clamp and the
carrler, and at the same tlme ensures rellable adjustment and
release ln the desired positlon of the plpe relative to the
carrler.
The lnventlon provides an artlcle to secure a continuous
pipe to a wall or the llke r comprising a plpe clamp having arms
that encircle the pipe and a carrier that is connected to the
clamp arms of the pipe clamp, characterized in that the free end
r

of the carrier or of the clamp arms of the pipe clamp is provided
with a frusto-conical detent; in that the detent is snapped at i~s
end face into a correspondingly formed, annular groove in the
opposite inner side of the clamp arms of the pipe clamp, or in the
opposite inner sides of clamp arms of the end area of the carrier;
and in that the snap connection thus formed can be tlghtened by
means of a screw that connects the clamp arms of the pipe clamp or
the clamp arms of the end area of the carrier, respectively, said
snap connection when loosened permitting rotation of the pipe
clamp and pipe about said carrier.
In an advantageous configuration the detent is
configured so as to have a truncated conical cross-section, with
an undercut on its wide end that enters into engagement behind a
corresponding step in the groove, which is configured so as to be
of a reversed truncated conical cross-section. Thls slmpllfies
the snap-fastening procedure and increases the clamping area.
In order to further increase the clamping area and
simpllfy the lnsertion process, in one embodiment it ls preferred
that the truncated conical detent of the carrier become a
similarly conflgured plug portion on its wide end, while forming
the undercut; a retaining rod of the carrier connects to this wide
end; an insertion opening that is of corresponding truncated
conical cross-section and that extends into the groove is formed
in the end face of the clamp arms of the pipe clamp. It is
expedient for the detent and the plug portion of the carrier be
configured as a separate, one-piece component secured to the
associated face of the retaining rod of the carrier by means of a

screw.
In any other embodiment of the present invention lt is
advantageously arranged that the outer side of the clamp arms of
~ ~9~32~i~
the pipe clamp extend from the undercut of the truncated conical
detent (which is divided because of the gap between the clamp arms)
parallel to the conical outer side of the detent; and that an
insertion opening that is of a corresponding truncated conical
cross-section be formed in the clamp arms of the end area of the
carrier.
According to a further advantageous development, the screw
that connects the clamp arms of the pipe clamp, or the clamp arms
of the end area of the carrier, respectively, is an hexagon-socket
set screw, the head of which rests in a screw-head countersink in
one clamp arm, the threaded stem of which passes through a bore
that is associated with this screw-head countersink, across the
gap between the clamp arms, and then engages in a threaded bore
in the other clamp arm.
In order that the groove can be produced in the component
that contains it in a simple manner in a moulding process, in an
advantageous version the circular groove in the inner sides of the
clamp arms is formed in conjunction with a transverse through
opening of trapezoi.dal cross-section that extends at right-angles
to and in the centre of the gap between the corresponding clamp
arms.
It is pre:Eerred that the retaining rod of the carrier be
bent to form a right-angle and, on its end face that is -to be
proximate to a wall of metal, is formed as a threaded pin that is
screwed into a matching threaded hole in the wall. As an alternative
to this, the retaining rod of the carrier can be relatively short
1~982~
and straight and, at its end face that is to be proximate to a wall
of wood, is formed as a wood screw. In a further advantageous
alternative, in the configuration of the carrier where the opposite
clamp arms make a direct transition to become a short retaining
rod of the carrier, a bore that is on the axis of the groove
extends from the groove through -the retaining rod, in which the
bore is necked down, and accommodates a screw that is screwed into
an anchor that is set in the wall.
In order to achieve an article that is both light and
weather-resistant, all the components thereof are of aluminum.
The underlying concept of the present invention will be
described in greater detail below on the basis of the drawings
appended hereto, wherein:

The pipe clamp 2 has a rounded part 1 that encircles the
pipe 3. The clamp arms 2a, 2b of the pipe clamp have a gap 4 between
them and are joined to each other in the area that is adjacent to the
pipe 2 by a screw 5. The head 6 of this screw 5, which is a hexagon-
socket set screw, is accommodated in a counter-sunk bore 7 in clamp
arm 2a having a section 8 for the threaded stem 9 of the screw 5
extending from the recess 7. Opposite this bore 8, in clamp arm 2b
there is a threaded bore 10, into which the threaded stem 9 of the
screw 5 is engaged.
On the inner sides 11 of the clamp arms 2a, 2b is a
circular groove 12 of truncated conical cross-section. An insertion
opening 14 extends from the broad end of the groove 12, to the end
face of the clamp arms 2a, 2b, this opening also being of truncated
conical cross-section, to define a step 13. The outer sides of ~he
groove 12 and of the inser~ion opening 1~ are parallel. The circular
groove 12 in the inner sicles 11 of the clamp arms 2a, 2b of the pipe
clamp 2 is formed in conjunction with a continuous transverse opening
15 of trapezoidal cross-section that extends at right-angles and
centrally in the gap 4 between the clamp arms 2a, 2b.
The end of the ca.rrier 16 for the pipe clamp 2 is shaped
as a truncated conical detent 17 ~Figure la) having an undercut
portion 18. This detent 17 is of a truncated conical form that is
the reverse of the groove 12. This makes a transition from the
undercut 18 of the detent 17 in a similarly configured plug section
19, i.e., the plug section 19 is also of truncated conical cross-
section. A retaining rod 20 of the carrier 16 is connected to the
broad side of the plug section 19. Since the groove 15 matches
B

the detent 17 and the insertion opening 14, a snap connection 21
can be produced between them by simply inserting these parts into
each other; when this is done, the undercut 18 of the detent 17
snaps into place behind the step 13 in the groove 12. When the
screw 15 is not tightened, the pipe clamp 2 with the pipe that it
encircles can thus be rotated through 360 degrees around the axis
22 that passes through the carrier 16, i.e., the longitudinal axis
23 of the pipe 3 can be rotated through the angular range ~h
(Figure 2). As soon as the pipe 3 has been rotated into its final
position, the screw 5 is tightened, which means that the snap
fastening 21 and the pipe clamp 2 are both fixedly secured.
The detent 17 and the plug section 19 are formed as a
separate one-piece unit 24 that is secured to the retaining portion
20 of the carrier 16 by an hexagon-socket set screw 25. The head
of this set screw 25 is set flush with the narrow end of the detent
17, whilst its threaded stem engages in a threaded blind bore 26
in the end of the retaining rod 20. On the underside of the unit
24 there is a recess 27 to accommodate the end face oE the retain-
ing rod 20. In this way, the unit 24 can be Eirmly attached to
the retaining rod 20.
The other end of the retaining rod 20 that is bent at right-
angles (Figure 1) carries an integral threaded pin 28 that can be
screwed into suitable threaded bore 29 in a metal wall 30. The
shoulder 31 of the retaining rod 20 is then flush with the wall 30.
In order to make it easier to screw the carrier 16 into the wall
30, the retaining rod 20 has two flats 32 on opposite sides of and
close to the threaded pin 28, and these can accommodate an open-
ended wrench.

In the embodiment shown in Figures 3 and 4, which is
essentially the same as that of Figures 1 and 2, the retaining rod
is straight and relatively short; the end that is proximate to the
wall, which in this instance is of wood, is formed as a wood screw
33 that can be screwed into the wall.
In thls case, too, the pipe 3 enclosed within the pipe
clamp 2 can be moved freely through the angular range ~v (Figure
4) about the axis 22, i.e., the longitudinal axis 23 of the pipe
3 can be rotated through 360 degrees about the transverse axis 22
of the pipe clamp 2.
The embodiment of the article as in Figure 5 is configured
similarly to the article shown in Figure 3, albeit with the
difference that the detent 15 is arranged at the free ends of the
clamp arms 2a, 2b of the pipe clamp 2 and the groove 12 is in the
inner sides of the clamp arms 16a, 16b of the end area of the
carrier 16. The clamp arms 16a, 16b are conflgured as are the
clamp arms 2a, 2b of the pipe clamp 2 as in Figure 3, and are also
connected to each other by a screw 5. Also the case of the
embodiment shown in Figure 5, the pipe 3 can be rotated about the
axis 22 as desired, because of the snap fastening 21 between the
pipe c]amp 2 and the carrier 16. A continuous bore 34 extends
from the groove 12 in the clamp arms 16a, 16b of the carrier 16
through the retalning rod 20, the bore 34 being stepped so as to
accommodate a screw 35. The screw 35 engages in an anchor 36 that
is inserted in a blind bore 37 in a concrete wall 30.

~The precedi.ng description, based on the drawings appended
hereto, reveals in detail the particularly simple and practical
design of the article according to the present invention, which is
extremely reliable despite its simplicity. Even though the invention
has been described only on the basis of a small number of
embodiments, there are many possibilities open to the expert to
modify these within the framework of the appended claims, these
possibilities being clear from the description. For example rather
than being on the carrler 16 the frusto-conical detent can be
provided on the pipe clamp and received in a groove or recess defined
in clamp arms (not shown) of the carrier 16.
