Description
The present invention relates to a garbage bag holder for mounting
on one of two cupboard parts movable relative to each other and
having a polygonal rod system consisting of mutually articulated
rods and adapted to carry a garbage bag at its open end and to
assume, on the one hand, an open position in which the garbage bag
is kept open and, on the other hand, a closed position in which the
bag is kept pressed flat at its open end.
Garbage bag holders of this kind which, for instance, are known
from British Pat. specification No. 1,073,895, may, in theory, be
mounted on any kind of wall which does not have to be one of two
cupboard parts movable relative to each other, for example a
cupboard door. One of the rods in the rod system is fixed on the
wall and the rod system is opened or closed by another rod being
moved manually away from or towards the fixed rod. Means may be
provided for keeping the rod system in the closed position.
In contradistinction to this, the garbage bag holder according to
the invention is characterized in that two components of the rod
system are each coupled to one of the movable cupboard parts.
Hereby is achieved that the rod system, and with it the garbage
bag, are opened and closed automatically by moving the two cupboard
parts relative to each other, for instance, by opening and closing
a cupboard door, which amounts to a considerable facilitation in
the use of the garbage bag holder.
It is remarked that a garbage bag holding frame having a rigid,
preferably rectangular frame, e.g. of plastic-coated steel wire, is
known, to which a garbage bag may be fixed. The opening and closing
of the bag takes place by means of a lid that is hinged in the
frame and which can be moved between a position in which it rests
on top of the frame and an approximately vertical position. The lid
can be opened and closed by opening and closing the cupboard door,
e.g. by means of a cord. The amount of garbage that can be put into
the bag in such a garbage bag holder is smaller than the amount
that can be put into the bag in a holder according to the invention
or in the known holder first mentioned, since above the frame there
must be a vacant space which renders the movement of the lid
possible. This means a reduction of the possible height of the
garbage bag, which height, in frames having a rod system is, to all
intents and purposes, determined solely by the height of the
cupboard door.
The rod system in the garbage bag holding frame may be of many
different shapes. It may, for instance, be quadrangular, pentagonal
or hexagonal and it can be equilateral or comprises rods of various
lengths. Those components of the rod system which are coupled to
the movable cupboard parts, may be the rods of the rod system or
pivot joints. The coupling may be effected at one of the vertices
of the rod system or one of the rods may be rigidly connected with
the door or the frame. On of the connections is, by way of
preference, easily releasable.
In the case in which one of the rods of the rod system is fixed to
one of the movable cupboards parts, a particularly simple
construction is obtained, in that in conformity with an embodiment
of the holder according to the invention, spring means are
incorporated into the rod system for influencing the rod system
towards the open or the closed position, and in that there is a
stop for the rod system intended for being fixed to the other
cupboard part. If the rod system is influenced towards the open
position by the spring means, a disconnection of the coupling
between the other cupboard part and the rod system takes place
automatically when the two cupboard parts are moved a certain
distance from each other.
As a consequence of the movement of the bag at its open end, which
occurs with each opening and closing of the bag, special measures
are needed for ensuring that the bag, despite its simple mounting,
is held securely in the rod system without being torn apart.
According to the invention, the rod system may have a plurality of
projections of rounded-off cross section for engagement with a
corresponding number of holes punched in advance in the garbage
bag.
The invention also relates to a garbage bag for use in the garbage
bag holder according to the invention, which bag is characterized
in that near the open end it has a plurality of holes of such a
shape and spaced apart in such a way that it is easy to hook the
bag on to the projections of the rod system, in addition to which
the circumference of the bag at the open end corresponds
approximately to the total length of the rod system. A secure
fixing of the bag on the frame, as well as an effective closing of
the bag is achieved hereby, the bag fitting tightly against the rod
system essentially without any creases.
In the following, the invention is explained in greater detail with
reference to the diagrammatical drawing, in which
FIGS. 1 and 2 show a garbage bag holder according to the invention
fixed to a cupboard door and seen from above and from the side,
respectively,
FIG. 3 a detail of the rod system in the holder shown in FIGS. 1
and 2.
FIG. 4 in perspective another detail of the rod system in the
closed position corresponding to FIG. 2, and
FIG. 5 a part of a garbage bag for use in the holder shown.
In the shown embodiment of the garbage bag holder, an annular
member is constituted of a rod system which, in the embodiment
shown, comprise six rods 1-6. The rods are articulated with each
other, so that the rod system can be in an open position, as shown
in FIG. 1, or in a closed position, as indicated in FIG. 2. The rod
1 is fixed, for instance by being screwed, on a cupboard door 7,
which is hinged to a frame 8 underneath a kitchen table 9.
In two of the pivot joints of the frame, e.g. pivot joints 10 and
11, a spring 12 is fitted, vide FIG. 3, which influences the rod
system in the direction of the open position shown in FIG. 1. Pivot
joints 10 and 11 have movement -limiting members, e.g. projections
13 and 14 on the rods 3 and 5 which, in the open position, abut
against parts of rods 2 and 6, so that it is impossible for the
springs to open the rod system beyond the position shown in FIG.
1.
On the topmost horizontal part of the frame 8, an elongated plate
15 having a longitudinal slit 16 is mounted, in which a pin 17 is
fitted which can be adjusted to any desired position in the slit.
When the cupboard door 7 is closed, that is to say, moved from the
position shown in FIG. 1 to the position shown in FIG. 2, the rod 4
will come to abut against the pin 17 and by continuous movement of
the door, the rod system will be deformed and will finally assume a
position in which all rods lie parallel, in that the rod 4 abuts
against rod 1, rod 3 against rod 2 and rod 5 against rod 6. The pin
17 is adjusted in such a way that this position of the rod system
is obtained at the very moment when the door is closed completely.
When the door is reopened, the rod system will again be brought
into the position shown in FIG. 1 by means of the springs 12.
The rods 2 and 6 each have a projection 18 and 19, which comes to
abut against the inside of the cupboard door 7 when the rod system
occupies the position shown in FIG. 2.
In the rod system, the open end of a garbage bag 20, e.g. a plastic
bag, is suspended. In order to ensure the attachment of the bag on
the rod system, the latter has a plurality of projections 21 which
engage corresponding holes 22 in the bag, vide in particular FIGS.
4 and 5.
The bottom of the bag is supported by a tray 23, which is fixed to
the door 7. When the holes 22 are to be punched in the bag, same is
expediently folded in such a way, vide e.g. FIG. 5, that it is
possible to punch several holes in the bag with a single punch.
With the kind of bag that is shown in FIG. 5, the rod system may be
so arranged that the two pivot joints 10 and 11 are moved inwards,
that is to say, towards each other, when the rod system moves from
the open position the closed position.
In the embodiment shown in the drawing, the cross section of the
individual rods is roughly U-shaped. It is possible to employ rods
having other cross sections. The rod system does not necessarily
have to consist of six rods as in the embodiment shown. The
employment of other numbers of rods is also possible. The spring
force in the pivot joints may be such that it forces the rod system
towards the closed position. The connection between the rod system
and the frame 8 has in such a case to be of such a kind that the
frame is forced towards the open position against the spring force
when the door is opened. The rod system need not be fixed to the
door 7 by means of one of its rods, as one of the pivot joints may
be connected to the door. In this case, one of the other pivot
joints can, for instance, be connected with the frame 8.
It is not necessary for the projections to have the shape shown in
the drawing, they may be of any other shape that is suitable for
holding the garbage bag. Nor do the holes have to be of the shape
shown. All that is required is that they be suitable for being
fitted on to the projections of the rod system.
The annular member does not have to be constituted of a rod system
with pivot joints. Its deformability may be obtained be a material
which in itself is elastically deformable, e.g. plastic material.
It is also possible to replace the pivot joint of the rod system
with such a material.
