[0001] This invention refers to a lavatory seat with back board for public lavatories, offices,
etc., adapted for distributing and placing lavatory seat sheets made of paper or similar
material. This invention intends to resolve, in a practical and functional manner,
the problem which arises in public and/or communities water closets with ensuring
hygienically safe seats of the water closet bowl. This solution has been studied in
many practical trials and considering its rather simple, it is believed that it can
have a wide range of application. Essentially, the invention foresees that the usual
lavatory seat, only slightly modified, is linked together and attached to the back
board by a hinge. The back board is rather thick, it leans against the wall and it
contains a pile of of hollow punched paper (or other appropriate material) sheets
suitable to act as seat covers. The lavatory seat sheets have rubber in specified
areas which have the function of making it possible to automatically detach a single
sheet and assure a certain antislip effect in coming in contact with the lavatory
seat.
[0002] The lavatory seat, according to the invention, is represented as a non-exhaustive
example in the following design, the figures of which demonstrate:
Fig.1 - A perspective view, in the standard position, of the lavatory seat properly
installed and one embodiment of the back board hinged to the lavatory seat containing
a pile of hollow punched lavatory seat sheets. The lavatory back board is leaned against
the nearby room wall - not shown - and shows the lavatory seat sheets ready for individual
withdrawl from the pile.
Fig.2 - A view halfway through the operation of deataching a lavatory seat sheet,
during which the lavatory seat is raised operating on the suitable anteriorly applied
handle.
Fig.3 - A view at the end of the phase represented in fig.2, where a small plaque,
with an adhesive surface, that is part of said handle, touches the corrisponding rubber
area found on the lavatory seat sheets.
Fig.4 - A view during the phase of lowering the lavatory seat with the lavatory seat
sheet adhering to it in the correct position.
[0003] As clearly shown in the said figures, the invention is based on a normal lavatory
seat (1) for lavatories in which anteriorly a handle (2) for raising the lavatory
seat is applied. A back board (3) is hinged posteriorly to the lavatory seat, it has
a certain deepness in order to contain a certain number of hollow punched lavatory
seat sheets (4) of paper or other material with similar characteristics. For reasons
described further on, the handle (2) for raising the lavatory seat has on its upper
surface an adhesive area shaped as a rectangular plaque housed in a proper housing
cavity foreseen on the lavatory seat. The handle is attached to the lavatory seat
with screws (5) which also have the function of fixing two pads (6) of auto-adhesive
or rubber strips with long lasting properties. The lavatory back board (3), as shown
in the figures, possesses an adequate form to the lavatory seat (1) and it has peripheriacally
a rather high border which acts as a place holder for the pile of lavatory seat sheets
that it contains. This is further assured by an appropriately shaped protrusion (7)
which originates from the central zone of the back board in order to act on the internal
hole in the hollow punched lavatory seat sheets (4).
[0004] The whole is finished by a couple of supports or pins (8) applied to the internal
border of the back board (3) in order to be easily replaced. These supports (8) have
the function of holding the remaining lavatory seat sheets (4) when an individual
seat is withdrawn. The ideal protrusion of the supports with respect to the functioning
may depend on the inclination that the back board (3) assumes when leaning against
the wall. Therefore the supports can be substituted with others of varying lengths.
[0005] According to another characterizing embodiment of the invention, the hollow punched
lavatory seat sheets (4) are singularly treated with rubber latex applied on areas
as followed: on the anterior zone (9) with a rectangular surface which sticks (fig.3)
to the adhesive pads (6) of the plaque of the lifting handle (2) and on the two central
zones (10 and 11) in the curved shape of the oval hollow punched sheets. This assures
the robustness of the structure of the paper material of the sheet and also an antislip
function when in contact with the lavatory seat (1) which assures a correct positioning
of the sheet in the withdrawing and utilization phases. It is important to underline
furthermore that the latex in such areas comes from a rather elastic and resistant
film which keeps the skin of the buttocks from coming in contact with the lavatory
seat in case the lavatory seat sheet rips.
[0006] All of the above as described and represented, susceptible to changes and perfectioning,
being the fundamental concept of the invention and realization with the materials
and dimensions held to be most appropriate.
1. Lavatory seat for public lavatories, offices, etc., adapted for distributing and
placing lavatory seat sheets made of paper or other similar material, characterized
by the fact that it is linked together by a hinge to the back board of appropriate
shape which is leaning against a wall, the lavatory back board is rather thick so
that it can contain a certain number of lavatory seat sheets of hollow punched paper,
sheets that at each raising of the lavatory seat are withdrawn one by one.
2. Lavatory seat as claimed in claim 1, characterized by the fact that anteriorly,
in the appropriate lowered position, the lavatory seat has a protruding handle for
raising the seat, the handle, which on its rectangular base has one or more holding
pads of adhesive material which coincide with the corrisponding zone of the hollow
punched lavatory seat sheets traeted with rubber latex.
3. Lavatory seat as claimed in claims 1 and 2, characterized by the fact that the
relative hinged back board has at its center a shaped protrusion raised from it which
acts on the internal hole of the hollow punched lavatory seat sheets to hold them
in place.
4. Lavatory seat as claimed in claims 1 to 3, characterized by the fact that the hinged
back board, has superiorly, on the internal part of its border, a couple of replaceable
supports or pins protruding from it which have the function of holding in place, up
to a certain limit, the lavatory seat sheets, at the moment of withdrawl of an individual
sheet, by the holding pads foreseen anteriorly on the actual lavatory seat.
5. Lavatory seat as claimed in claims 1 to 4, characterized by the fact that the lavatory
seat paper sheets destined to be withdrawn by the lavatory seat when it is raised
completely, have on each sheet a small zone treated with rubber latex positioned in
such a way as to come in contact with the holding pads foreseen on the plaque that
is found on the handle which protrudes from the anterior part of the lavatory seat.
6. Lavatory seat as claimed in claims 1 to 5, characterized the fact that the lavatory
seat paper sheets, close to the hollow punched oval internal hole, in at least two
other areas, have on each one areas treated with rubber latex which have an antislip
function and act also as a reinforcement of the paper fiber of which the sheets are
made.
