An arrangement in a waste container furnished with replaceable refuse sack
(6) and having a body supporting the refuse sack from the inside, the
purpose of which is to keep by use refuse sack (6) open substantially in
its largest size, when the refuse sack (6) is together with the said body
fitted into a bin construction suitable for the purpose. The inside body
is formed of walls of plate construction or, for instance, of net
construction (2, 3), of which at least one wall (3) is movable in order
to increase the volume formed by means of said walls.
1. An arrangement in a waste container furnished with replaceable refuse
sack (6) and having a body supporting the refuse sack from the inside,
the purpose of which is to keep by use the refuse sack (6) open
substantially in its largest size, when the refuse sack (6) is together
with the said body fitted into a container construction suitable for the
purpose, characterized in that the inside body (2),(3) is formed of plate
walls or, for instance, walls of net construction, of which walls at
least one wall (3) is movable outwards by means of gravitation force in
order to increase the volume formed by said walls.
2. An arrangement according to claim 1 characterized in that movable wall (3) is fitted to move outwards or inwards by means of gravitation force, whereby the fastening of said wall (3) to other body wall (2) is arranged, for instance, by means of an oblong diagonally directed hole (4) and a fixing means (5) moving in it.
3. An arrangement according to claim 1 characterized in that the container construction comprises a supporting bottom part and when the body parts (2,3) locating inside the refuse sack is lowered onto said bottom part the lowering causes between the body parts (2),(3) a mutual motion in vertical direction, wherein at least one wall (3) of the walls moves also sideways due to the diagonal directed hole (4).
4. An arrangement according to claim 1 characterized in that it comprises two movable walls (3) in the opposite sides of said refuse sack and the walls is arranged to move towards each other when the walls (3) is lifted up by means of grip taken from the other body parts (2).
5. An arrangement according to claim 1 characterized in that movable body parts (3) are fitted to move away from each other when lowered them down onto to the bottom part of the container construction by arranging movable wall (3) at first to touch the bottom part and the later lowering of the other body part (2) down towards the bottom part causes, due to the diagonal mutual fastening, a transversal motion to the wall (3).
6. An arrangement according to claim 1 characterized in that the transversal motion of the wall (3) is arranged to make the residue sack (6) to strain around the body parts (2), (3).
7. An arrangement according to claim 1 characterized in that residue sack (6) forms at least partly the outer surface for the container mantle.
The invention relates to an arrangement in a waste container
furnished with replaceable refuse sack and having a body supporting the
refuse sack from the inside, the purpose of which is to keep the refuse
sack by use open substantially in its largest size, when the refuse sack
is together with the said body fitted into a waste container construction
suitable for the purpose.
In known refuse bins the refuse sack is replaced inside the container body, whereby the refuse sack gets supported from the outside by use. In known solutions the body supporting the refuse sack from the outside is usually a solid wall of plate structure. The filled refuse sack is lifted from refuse bin or the container mantle or bottom is detachable, whereby the refuse sack can be removed without lifting it. By use the refuse sack is hidden inside the container.
When it is wanted to do a refuse sack embodiment, where the sack is visible, the wall that supports the sack may not be outside the sack. The supporting walls must be placed inside the refuse sack. If the replaceable refuse sack works also as advertising surface having advertising printings, the sack surface must be quite smooth and not creased, in other words, stretched to proper tightness.
Known are arrangements to facilitate removal off and fitting of the refuse sack. onto the body, for instance from patent publications GB 109676, U.S. Pat. No. 3,983,914, U.S. Pat. No. 4,037,778, U.S. Pat. No. 6,179,150 and U.S. Pat. No. 6,367,747.
The motive of the invention is to present a body supporting a refuse sack to be placed into a refuse sack, which body independently and automatically stretches the advertising surfaces of the refuse sack, whereby the refuse sack is still easily replaceable. The invention is characterized in that the inside body is formed of walls of plate structures or for instance of net structures, of which at least one wall can be moved by means of the force of gravity in order to increase the volume formed by means of said walls.
Characteristic for the other embodiments of the invention is that what is presented in the dependent claims.
The advantage of the arrangement according to the invention is that the refuse sack can be made an easily fitted and easily emptied sack although it is in usable position tense by means of bodies inside the refuse sack. By means of the arrangement at least a part of the bodies can be made movable as much as needed so that the refuse sack gets more tense by use and that on replacing the sack so much slack is formed that the refuse sack is easily put to rest on the body parts and removed from them. The shift of body parts to broader or the narrower position simply takes place automatically by means of gravitation, when another body is lifted.
In the following the invention is disclosed with reference to the enclosed drawing, where
FIG. 1 shows a body meant to support a refuse sack placed in a waste container.
FIG. 2 shows body 1 shifted into broader position,
FIG. 3 shows a portion of the refuse sack made tense by means of the body parts.
FIG. 1 shows the body to be fitted in refuse bin in order to support the refuse sack. The body is made of an upper frame 1, from which opposite walls 2 go downward. Other walls 3 are loose from upper frame 1 and fixed to walls 2 by means of oblong diagonally fitted holes 4 and screws 5. Thus walls 3 can move outward and upwards from the FIG. 1 position as much as the distance of hole 4. Body parts 2 and 3 get inside the refuse sack. In an advantageous embodiment the refuse sack getting around the body parts remains for the most part visible and works as replaceable, when having advertising printings.
In FIG. 2 the body parts 2 and 3 have got upward and at the same time drawn away from one another. This-happens, for instance, if body parts are placed on an even cover, whereby their bottom edges get on same height, which means upward rise of parts 3. The enlargement part of FIG. 2 shows a diagonally directed groove 4 for screw 5, the large screw-head does not fit through groove 4.
In FIG. 3 the body parts inside refuse sack 6 are at their most extensive, whereby parts 3 stretch the refuse sack into a square form The printings on the refuse sack surface get then quite visible.
Instead of plate constructions parts 2 and 3 can be nets, especially sheets of net. Instead of square construction the body construction can be round or of some other shape.
Most suitably the body can be without bottom, whereby refuse sack 6 is removed pulling downwards and the refuse inside parts 2 and 3 fell at the same time into the refuse sack at the. The body parts are then in the position of FIG. 1. In this position also a new refuse sack 6 is mounted as replacement. In one embodiment still another refuse sack is placed inside the body parts, whereby a double protection for the residue is achieved.
