[0001] The present invention relates to a public sanitary facility, comprising a housing
intended for placing underground, and a wall adapted to collect urine, which wall
is mounted on the housing for pivoting between an underground rest position and an
above-ground position of use.
[0002] Such a sanitary facility is described in Netherlands patent
1032131 of applicant.
[0003] The known public sanitary facility can be placed ready for use as required in rapid,
simple and safe manner. A temporary toilet facility can hereby be provided in public
spaces without any permanent change to the street scene, whereby the problem of public
urination can be solved satisfactorily.
[0004] In the retracted situation the known sanitary facility takes up only minimal space
under the ground and can be placed at any location despite the possible presence in
the ground of objects such as conduits for water or electricity.
[0005] The present invention relates to an improvement to the known public sanitary facility.
[0006] The public sanitary facility according to the invention has for this purpose the
feature that the housing also comprises a floor which is movable between a rest position,
in which the floor is situated in the housing, and a position of use in which the
floor is situated substantially parallel to street level.
[0007] The movable floor has the significant advantage that in the position of use there
are no longer any height differences between the surrounding level (referred to here
with the term street level) and the walkable surface of the public sanitary facility
according to the invention. This enhances safety for users, this being of great importance
in public spaces.
[0008] In a first preferred embodiment of the public sanitary facility according to the
invention the sanitary facility is adapted for simultaneous movement of the floor
and pivoting of the wall. The public sanitary facility can hereby be placed into the
position of use in one movement, and likewise disappear underground again in one movement.
One central drive moreover suffices for the purpose of performing this movement, which
saves production costs.
[0009] According to a practical development of this first preferred embodiment, the floor
comprises at least two floor parts which are pivotally connected. A first floor part
is provided with guide means, wherein a guide rail is arranged in the housing for
guiding the guide means. A second floor part is mounted fixedly on the wall. According
to this further development, the floor as it were co-displaces during the pivoting
of the wall under the influence of the central drive. The floor is hereby embodied
mechanically in robust and reliable manner and produces a surface which any user can
walk on safely.
[0010] According to a further preferred embodiment, means for cleaning the sanitary facility
are arranged in the floor. These cleaning means co-displace with the floor during
displacement between the rest position and the position of use. As a result the public
sanitary facility according to the invention can be cleaned hygienically in reliable
manner in a short period of time.
[0011] In a further preferred embodiment the floor is adapted such that it serves in the
position of use as closing element of the housing. Using the floor the hollow housing
is immediately covered and secured in the position of use.
[0012] In an elegant preferred embodiment the wall is provided with one or more walk-in
positions, each with a receptacle for human excrement and/or urine, which is connected
to a waste pipe for connection to a sewage system. The housing with one or more walk-in
positions gives a user privacy, this being perceived as important in public spaces.
Owing to the movable floor and the hollow housing, the space required for accommodating
the one or more walk-in positions with receptacle can be created while the depth of
the housing remains the same.
[0013] In yet another preferred embodiment one of the sides of the wall is situated during
operation substantially parallel to street level in the underground rest position.
In the rest position the public sanitary facility according to the invention is immediately
covered and secured by means of the closing wall. The wall is preferably embodied
so as to be passable for traffic. In the rest position the public sanitary facility
can advantageously be integrated inconspicuously into the street scene without forming
an obstacle for traffic.
[0014] The public sanitary facility according to the invention is preferably adapted such
that the wall stands substantially perpendicularly of the street level in the above-ground
position of use thereof. In this embodiment the public sanitary facility can very
well be placed close to the wall of a building such that in the position of use the
urinal wall extends parallel to the wall of the building. The public sanitary facility
according to the invention will also not then form an obstacle for traffic in the
position of use.
[0015] The invention will now be discussed in more detail with reference to the drawings,
in which
Figure 1 shows a schematic cross-section of a preferred embodiment of a sanitary facility
according to the invention in the position of use;
Figure 2 shows a schematic cross-section of the sanitary facility of figure 1 in rest
position.
Figure 3 shows a schematic cross-section of the sanitary facility of figure 1 in a
position between the rest position and the position of use; and
Figure 4 shows a schematic top view with broken-away parts of the sanitary facility
of figure 2.
[0016] Figure 1 shows a schematic cross-section of a sanitary facility according to the
invention in the form of a urinal 1 in a first preferred embodiment.
[0017] Urinal 1 has a housing 2 intended for placing underground. The height of housing
2 is less than the generally usual depth for placing of underground conduits. In the
Netherlands this depth amounts to about 40 to 50 cm. Housing 2 can further take any
suitable form. The shown rectangular form of receptacle is for instance very suitable,
but serves only by way of illustration.
[0018] A wall 3 adapted to collect urine is mounted on housing 2. The wall is pivotable
between the shown above-ground position of use and an underground rest position as
shown in figure 2. In the above-ground position of use the urinal wall stands substantially
perpendicularly of street level S. In the underground rest position the upper side
3b of the urinal wall lies substantially parallel to street level S. Wall 3 hereby
also serves in advantageous manner as cover for closing the housing. Wall 3 is provided
with a finish on the side 3b visible in the rest position. This finish preferably
corresponds with the appearance of the pavement at that position, so that cover 3
can be integrated inconspicuously into the pavement. For the sake of clarity the figures
show urinal 1 without this finish.
[0019] Urinal 1 is provided with a floor consisting of two parts 10A and 10B. Parts 10A
and 10B are connected by means of hinge 10C. Part 10B is connected to housing 2 by
means of a hinge 23. The same hinge 23 connects wall 3 to housing 2. Floor part 10B
is fixedly connected to wall 3. Floor part 10A is provided at one outer end with guide
means 11, for instance guide rollers. Housing 2 takes an at least partially hollow
form and is provided with a rail 22 for guiding the rollers 11.
[0020] Wall 3 can be a urinal wall as described in the above stated Netherlands patent.
In the shown preferred embodiment however, the interior 30 of wall 3 is provided with
one or more walk-in positions. Each walk-in position has a base 10B and a urine basin
4 which can be connected to the sewage system by means of a waste pipe 6. In the shown
preferred embodiment urinal 1 has one walk-in position. The number of walk-in positions
can however be increased, for instance to two. The design of the interior 30 of wall
3 preferably corresponds to the design of the housing of the public sanitary facility
described in European patent
1232313 of the same applicant. This housing has generally cylindrical features with semicircular
forms.
[0021] The interior 30 thus takes an at least partially hollow form. Received therein are
a pair of mounting shoes 31, each serving as point of engagement for the drive, which
comprises a pair of hydraulic cylinders 13. Hydraulic cylinders 13 further each support
in hollow housing 2, preferably on the rear wall thereof.
[0022] Figure 3 illustrates the movement made by urinal 1 from the rest position to the
position of use, and vice versa. It can be clearly seen that cylinders 13 push wall
3 upward and herein co-displace the fixed floor part 10B. Floor part 10A is automatically
co-displaced here by hinge 10C and is guided upward along rails 22.
[0023] In the position of use the floor is supported on the front side by roller guides
11 which rest on the horizontal part of rail 22, and on the rear side at the position
of hinge 23. Cylinders 13 support the floor indirectly by supporting wall 3.
[0024] During the reverse movement (from position of use to rest position) cylinders 13
pull wall 3 with floor part 10B downward and herein force co-displacement of floor
part 10A.
[0025] The operation of the movement of the wall can take place both manually and automatically.
In both embodiments it is important that the operative has a clear overall view of
the situation at the particular location before placing the urinal in the position
of use or the rest position, so as to avoid hazardous situations for bystanders.
[0026] Figure 4 shows a schematic top view of urinal 1 in the rest position of figure 2.
Wall 3 has been omitted for the sake of clarity. Drainage means 6 can preferably be
connected by means of a connection 7 to a sewage system at the location. An electrical
connection 8 connectable to the local mains electricity provides the necessary electric
power. Lighting 5 is preferably arranged in the urinal, for instance by means of LEDs.
[0027] Further provided is a water connection 9 which connects the urinal to the local water
supply system. Spray nozzles 12 for cleaning the urinal are incorporated in floor
part 10A. The spray nozzles are activated automatically during movement of urinal
1 from the rest position to the position of use. Spray nozzles 12 are preferably controlled
for a predetermined period of time using a time switch. Since floor part 10A moves
relative to wall 3, spray nozzles 12 likewise move relative to interior 30, whereby
an excellent cleaning can take place.
[0028] Diverse materials are suitable for the sanitary facility according to the invention,
including metal (in particular stainless steel) and plastic.
[0029] It is expressly noted that the invention is not limited to the described and shown
preferred embodiment. The invention extends generally to any embodiment which falls
