Description
TECHNICAL FIELD
[0001] The invention relates to an actuation apparatus for a
functional device, having a pressure actuation element which is
connected to an axially displaceable control element, wherein the
control element has an application location which can be moved into
an active connection with the functional device or which is in an
active connection with the functional device in the position for
use. The functional device may be in particular a sanitary
functional device. For example, the actuation apparatus can be
configured to control a valve, in particular to move it into an
open position or into a closed position. Other functional units may
be, for example, a sanitary fitting and/or a toilet tank of a
toilet. By pressing the pressure actuation element, a pressing
force can be transmitted to the functional device via the control
element and the application location.
[0002] The invention further relates to the use of an actuation
apparatus for controlling a functional unit.
[0003] Finally, the invention relates to a method for producing an
actuation apparatus for a functional device.
BACKGROUND
[0004] Actuation apparatuses of the type mentioned in the
introduction have the disadvantage that the assembly and in
particular a correct orientation of a facing or a housing relative
to the actuation apparatus is often difficult to carry out.
Generally, the pressure actuation element is inserted in an opening
of the facing or the housing in the assembled state so that a
millimetre-precise orientation of the actuation apparatus and the
facing or the housing relative to each other is necessary.
SUMMARY
[0005] Consequently, the problem addressed by the invention is to
provide an actuation apparatus with properties for use which are
improved with respect to previously known actuation
apparatuses.
[0006] This problem is solved according to the invention by an
actuation apparatus having one or more of the features disclosed
herein.
[0007] In particular, an actuation apparatus of the type mentioned
in the introduction is proposed according to the invention in order
to solve the above-mentioned problem, wherein at least one
deformable compensation element is arranged or constructed between
the pressure actuation element and the application location,
wherein a position change of the pressure actuation element
relative to the application location in a radial direction is
possible as a result of the compensation element. The compensation
element allows the pressure actuation element to be subsequently
orientated correctly relative to an opening within a wall, for
example, of a housing and/or of a facing. Consequently, simpler
assembly of the actuation apparatus is possible because the
actuation apparatus and the housing and/or the facing can be
installed with greater tolerances during the precise arrangement
thereof.
[0008] Alternatively or additionally, in particular an actuation
apparatus of the type mentioned in the introduction is proposed
according to the invention in order to solve the above-mentioned
problem, wherein the compensation element fixes the control element
for different radially offset relative arrangements of the pressure
actuation element and the application location in a radially
play-free manner relative to each other. As already described
above, it is thereby possible to subsequently orientate the
pressure actuation element correctly relative to an opening within
a wall, for example, of a housing and/or a facing. Furthermore, in
the solution described it is not necessary or provided for a play
to be configured between the control element and the pressure
actuation element and/or between the control element and the
compensation element. Instead, the compensation element allows the
position of the pressure actuation element to be freely adjusted
relative to the application location.
[0009] Advantageous embodiments of the invention which can be
combined alone or in conjunction with the features of other
embodiments optionally together with the above features are
described below.
[0010] According to a preferred embodiment of the actuation
apparatus, there may be provision for the at least one compensation
element to be in the form of an insertion element, in which a free
end of the control element can be inserted at different positions
and can be radially fixed or in which a free end of the control
element is inserted at different positions in the position for use
and is radially fixed. In this case, it may be particularly
preferable for insertion and fixing which are both central relative
to a geometric centre of the pressure actuation element and also
decentralised to be possible. Consequently, it is possible to
connect the pressure actuation element to the control element by
means of a practically free selection of position and to orientate
it correctly.
[0011] In order to allow particularly simple assembly, there may be
provision according to an advantageous embodiment for the at least
one compensation element to be constructed from a deformable mass,
in particular from a mass which is deformable in a reversible or
non-reversible manner.
[0012] Alternatively or additionally, there may be provision for
the at least one compensation element to have a plurality of
resilient bristles and/or bristle bundles which are bent when a
free end of the control element is introduced. In particular, the
bristles and/or bristle bundles can be configured in such a manner
that a retention force acts on the control element as a result of
the bristles and/or bristle bundles. The pressure actuation element
can thereby be fixed on the control element in the position for
use.
[0013] According to another advantageous embodiment, there may be
provision for the pressure actuation element to comprise a cap in
which the at least one compensation element is at least partially
received. Therefore, the cap can act as a counter-bearing when the
control element is introduced into the compensation element.
Alternatively or additionally, the cap may form a stop face for the
control element.
[0014] According to another advantageous embodiment, there may be
provision for a position change of the pressure actuation element
relative to the application location in a radial direction to be
prevented after the control element is introduced into the at least
one compensation element by a retention force which is produced by
the at least one compensation element. Consequently, it is possible
to prevent a user of a functional device who is actuating the
actuation apparatus from releasing or displacing the pressure
actuation element inadvertently.
[0015] In order to be able to better prevent the actuation element
from tilting when it is actuated by a user, there may be provision
according to an advantageous development for the control element to
extend through the compensation element in the position for use.
Consequently, a hole can really be formed in the compensation
element with the control element by a displacement of material
and/or bristles being brought about. A connection which can be
configured in a particularly simple manner and which is
nevertheless stable can thereby be produced between the pressure
actuation element and the control element.
[0016] According to another advantageous embodiment, there may be
provision for the at least one compensation element to be
constructed as a portion of the control element. In particular, the
at least one compensation element can be inserted as a portion into
a control rod of the control element. This embodiment can be
implemented alternatively or additionally to the construction
variant described above. It has the advantage that the pressure
actuation element practically orientates itself correctly during
assembly, for example, when it is inserted into a recess of a
facing and/or a housing provided therefor.
[0017] In order to be able to achieve an even simpler assembly,
there may be provision according to a development for at least
partial bending of the control element to be possible in the region
of the at least one compensation element, in particular at least
partial bending of a or the control rod of the control element, so
that the portion of the control element placed after the
compensation element is orientated at an angle obliquely relative
to a straight portion of the control element. Preferably, the
control element can be bent in such a manner that an end, which is
connected to the pressure actuation element, of the control element
is not located on a linearly extending longitudinal axis of a
non-deformed portion of the control element, by which portion the
application location is formed.
[0018] In order to configure the best possible force transmission
from the pressure actuation element to the control element, there
may be provision according to an advantageous development for a
stop face, in particular a stop face which is constructed on an
inner side of the cap, of a cap of the pressure actuation element,
for example, the already previously mentioned cap of the pressure
actuation element, to be constructed to be non-planar. In
particular, the stop face may have a concave curvature.
[0019] According to another advantageous embodiment, there may be
provision for the at least one compensation element, such as, for
example, a compensation element which is in the form of a part of
the control element, to be constructed as a restoring element,
preferably as a spring. Consequently, the provision of an
embodiment which is relatively simple and cost-effective to produce
is possible.
[0020] In order to fix a radial position of the application
location, there may be provision for the actuation apparatus to
have at least one guide for the control element. In particular,
this may be a guide for the portion of the control element which
has the application location. Thus, a radial position of the
application location may be non-variable as a result of the guide.
Alternatively or additionally, the compensation element can be
configured in such a manner that a radial position of the
application location cannot be changed by the compensation element.
Thus, a displacement of the pressure actuation element relative to
the application location cannot inadvertently be brought about.
[0021] The invention further relates to the use of an actuation
apparatus as described and/or claimed herein in order to control a
valve and/or a sanitary fitting and/or a toilet tank. Precisely in
the case of sanitary functional devices, in which at least
partially a layer of plaster is applied during assembly of a facing
and/or a housing, it is often difficult or impossible to carry out
subsequent fine orientation between the actuation apparatus and the
facing and/or the housing by the position of the application
location or the position of the opening for the pressure actuation
element to be adjusted relative to each other. Therefore, the
actuation apparatus according to the invention is particularly
suitable for use in such functional devices.
[0022] The invention further relates to a method for producing an
actuation apparatus for a functional device, for example, the
actuation device described and/or claimed herein, wherein a
pressure actuation element is orientated by means of a deformable
compensation element radially relative to an application location
of a control element. As already explained in detail above in
relation to the actuation apparatus, it is also possible by means
of the method according to the invention to carry out a simple,
subsequent orientation of the pressure actuation element. This is
particularly helpful when an opening of a facing and/or a housing
is also installed in a fixed manner and/or in the position in a
non-variable manner and the orientation of the pressure actuation
element is subsequently carried out.
[0023] According to an advantageous development, there may be
provision for a free end of a control element to be introduced into
the compensation element at a central and/or decentralised position
and fixed in this position in order to orientate the pressure
actuation element. Consequently, it is possible in a particularly
simple manner to allow a rapid assembly and/or correct orientation
of the components of the actuation apparatus by means of a free
relative arrangement between the control element and the pressure
actuation element.
[0024] According to another advantageous development, there may be
provision for the control element to be bent at a compensation
element which is inserted into the control element in order to
orientate the pressure actuation element. Consequently, it is
thereby possible to allow rapid assembly and/or correct orientation
of the components of the actuation apparatus.

DETAILED DESCRIPTION
[0036] FIGS. 1 to 10 show different construction variants of an
actuation apparatus according to the invention which are generally
designated 1. However, the invention is not limited only to the
embodiments shown in the Figures.
[0037] The actuation apparatus 1 is used to be able to operate a
sanitary functional unit. For example, it is possible to activate
an actuation mechanism therewith. Examples of sanitary functional
units may be, for example, a valve and/or a sanitary fitting and/or
a toilet tank.
[0038] The actuation apparatus 1 has a pressure actuation element 2
and a control element 3 which is brought into cooperation with the
pressure actuation element 2 in the position for use. A pressing
force which is applied by a user via the pressure actuation element
2 can be transmitted to the functional device by the control
element 3. To this end, the control element 3 has an application
location 4 in order to be able to connect the actuation apparatus 1
to the functional device.
[0039] If the actuation apparatus 1 is connected to the functional
device, the application location 4 with the functional device can
be displaced into an active connection so that a force transmission
is possible. There are known from the prior art a large number of
known application locations 4, such as different mechanical,
electronic, pneumatic and/or magnetic connections which are not
listed in detail herein.
[0040] The application location 4 may, for example, be constructed
at an opposite end to a free end 8 of the control element 3, which
free end 8 is connected to the pressure actuation element 2.
[0041] The actuation apparatus 1 has at least one compensation
element 5 which allows a plurality of different radial relative
arrangements of the pressure actuation element 2 in relation to the
application location 4.
[0042] Consequently, the compensation element 5 is arranged and/or
constructed between the application location 4 and the pressure
actuation element 2.
[0043] As a result of the compensation element 5, a position change
of the pressure actuation element 2 relative to the application
location 4 in a radial direction 6 is possible. Furthermore, the
compensation element 5 serves to fix the pressure actuation element
2 in a relative position in a radially play-free manner within an
opening provided therefor. This position change can be achieved in
different manners, as described below.
[0044] According to a construction variant shown in FIGS. 1 to 4,
the compensation element 5 may be in the form of an insertion
element 7. Consequently, a free end 8 of the control element 3
which is in the form, for example, of a pin, can be introduced into
the insertion element 7 and at least radially fixed therein. No
play is formed in a radial direction 6 between the pressure
actuation element 2 and/or the compensation element 5 and the
portion of the control element 3 introduced therein.
[0045] The portion of the control element 3 introduced into the
insertion member 7 may further have a rotation prevention member
21. In this case, for example, the rotation prevention member 21
can be constructed in that the portion has at least partially a
non-round cross section. In particular, the portion may have a
cross-like or star-like cross section.
[0046] Consequently, it is possible to introduce the control
element 3 both in a central position 19 and in a decentralised
position 20 with respect to a geometric centre 9 of the pressure
actuation element 2.
[0047] For example, the compensation element 5 may have a
deformable mass 10 which is preferably reversibly deformable or may
be produced from such a mass 10. The portion of the control element
1 provided for introduction into the compensation element 5 can
consequently be constructed to be stiffer than the mass 10 so that
a displacement and/or penetration of the mass is produced during
introduction.
[0048] Alternatively or additionally, the at least one compensation
element 5 may have a plurality of resilient bristles and/or bristle
bundles which are bent when a or the free end 8 of the control
element 3 is introduced. Consequently, a retention force can act on
the control element 3 and can fix it in its position as a result of
the bristles or bristle bundles.
[0049] The actuation apparatus 1 further has a cap 11. The cap 11
may be configured, for example, as a pressure actuation element 2,
for example, by a user being able to apply a pressing force to an
outer side of the cap 11. The pressure actuation element 2 may be,
for example, in the form of a push-button, a button and/or a
lever.
[0050] FIGS. 1 to 4 show that the compensation element 5 is at
least partially inserted into the cap 11. After the control element
3 is introduced into the compensation element 5, consequently, the
control element 3 is also partially introduced into the cap 11.
[0051] There is constructed at an inner side of the cap 11 a stop
face 12, against which the control element 3 strikes when it is
introduced into the cap 11 to the maximum extent. As a result of
the stop face 12, an axial position of the control element 3 can be
fixed relative to the cap 11.
[0052] The compensation element 5 produces a retention force which
acts counter to a position change in a radial direction after the
pressure actuation element 2 has been orientated relative to the
control element 3.
[0053] FIGS. 5 to 8 show an additional embodiment of an actuation
apparatus 1 which has a control element 3, in which a compensation
element 5 is inserted as an intermediate portion. The regions of
the control element 3 before and/or after the compensation element
5 can instead be constructed to be stiff. Preferably, consequently,
the control element 3 can be bent particularly only in the region
of the compensation element 5, preferably bent in a reversible
and/or non-destructive manner. Therefore, the at least one stiff
region serves to be able to axially transmit the necessary
actuation force. Consequently, the correct orientation of the
control element 3 is carried out once during assembly by means of
bending in the region of the compensation element 5. In the
assembled state, however, the control element 3 preferably does not
bend any further. The actuation function thereby remains
available.
[0054] Consequently, it is possible to bend the control element 3
in the region of the compensation element 5. In other words, the
compensation element 5 separates the control element 3 into a
portion 15 which is bent relative to a longitudinal axis (reference
axis) 17 (of a linear portion 16) and a straight, non-bent portion
16, wherein the bent portion 15 is redirected through an angle 14
relative to the non-bent portion 16. The application location 4 can
be constructed on the non-bent portion 16. The straight portion 16
and/or the reference axis 17 may be located at an output side of
the actuation apparatus 1. The portions 16, 17 which are separated
from each other by the compensation element 5 can be constructed to
be stiffer than the compensation element 5. Preferably, the
portions 16, 17 can be constructed in a stiff manner so that they
do not bend when used correctly, in particular do not bend in a
radial direction, and are therefore used to transmit force in an
axial direction via the output side. Accordingly, the reference
axis 17 corresponds to a longitudinal axis 17 of a linearly
extending and/or non-redirected control element 3. By redirecting
the control element 3 via the compensation element 5, it is
possible to configure a contact point between the control element 3
and the cap 11 in a central position 19 of the cap 11 or at least
practically central position 19 of the cap 11. Therefore, a better
force transmission is possible, particularly when a pressing force
is applied.
[0055] In this instance, the control element 3 has a control rod
13, wherein the compensation element 5 is in the form of an
intermediate piece of the control rod 13. In order to achieve the
deformability of the compensation element 5, the control element 5
can be constructed to be thinner at least partially in the region
of the compensation element 5 and/or can have a diameter which is
reduced in terms of cross section. In particular, at least one
material recess, by which the compensation element 5 is
constructed, can be provided on the control element 3.
[0056] In this construction variant, a stop face 12 is also formed
by the cap 11. The stop face 12, which is also formed at the inner
side of the cap 11 in this case, of the cap 11 of the pressure
actuation element 2 is constructed in a non-planar manner, in
particular constructed in a concave manner. In this case, a lowest
point of the cap is arranged centrally, preferably wherein a
geometric centre 8 of the pressure actuation element 2 and the
lowest point are located on a common axis, in particular located on
the longitudinal axis 17 (of a non-bent control element 3) or
located on an axis parallel with the longitudinal axis 17. This
embodiment has the advantage that the pressure actuation element 2
is orientated relative to the application location 4 during
loading. A contact point (or a contact face) between the stop face
12 and the free end 8 of the control element 3 is no longer located
on the longitudinal axis 17 when the control element 3 is
redirected through an angle 14 by means of the compensation element
5, as can be seen in FIGS. 6 and 7. The contact point and/or the
contact face may preferably be located at the lowest region of the
cap 11 in this case.
[0057] The compensation element 5 is preferably in the form of a
restoring element 18 so that a pressing pressure of the control
element 3 on the stop face 12 can be developed by the restoring
force of the restoring element 18, preferably by which restoring
force even better fixing is possible.
[0058] The actuation apparatus 1 may further have a housing and/or
a cover and/or a facing, wherein an opening and/or a recess for the
pressure actuation element 2 is provided therein, wherein a change
in the relative position between the pressure actuation element 2
and the application location 4 of the control element 3 can be
achieved by the above embodiments of the compensation element 5 so
that a play-free arrangement of the pressure actuation element 2
inside the opening is possible. Therefore, there may be provision
for a spacing between the pressure actuation element 2 and the edge
of the opening to be completely uniform.
[0059] The construction variant of FIGS. 9 and 10 constitutes a
combined version of the construction variants of FIGS. 1 to 8.
Furthermore, FIGS. 9 and 10 additionally also illustrate a
connection means 22, at the output side of the control element 3,
which may generally also be part of the actuation apparatus 1 and
via which an axial force transmission is possible. FIG. 9 shows the
non-mounted state and FIG. 10 shows the mounted state. For example,
the connection means 22 may be a snap-fit connection. Consequently,
pressure forces and tensile forces can be transmitted via the
control element 3. Furthermore, a snap-fit connection can be
configured in a particularly simple manner without tools being
necessary for this.
[0060] Consequently, the invention particularly relates to an
actuation apparatus 1 for a functional device having a pressure
actuation element 2 for carrying out a pressing movement which is
connected to an axially adjustable control element 3, wherein the
control element 3 comprises an application location 4 which can be
displaced into an active connection with the functional device or
which is in an active connection with the functional device in the
position for use, wherein at least one compensation element 5 is
arranged or constructed between the pressure actuation element 2
and the application location 4, wherein a position change of the
pressure actuation element 2 relative to the application location 4
is possible in a radial direction 6 as a result of the compensation
element 5.
