Collecting device for refuse, dust etcetera

A refuse collector including a casing for a receptacle and a holder for a magazine of hose-shaped material in which the holder is movably mounted in relation to a support. The hose-shaped material is drawn from the holder into the casing to form a receptacle. The holder may be moved in relation to the support so as to enable a filled receptacle to drop out of the bottom of the casing. When the filled receptacle is discarded, the material stored in the holder is drawn into the casing and is ready to receive more refuse. In one embodiment, the holder is pivotally mounted to the support while in a second embodiment the holder may be moved vertically with respect to the support.

The present invention relates to a collecting device for refuse, dust 
etcetera. 
One object of the invention is to provide a collecting device in which the 
receptacle for the refuse etc. is produced from a long, hose-shaped 
packaging material and in which several bags can be produced consecutively 
by drawing a sufficient length of packaging material from a magazine or 
storage of such material. 
Another object of the invention is to provide a collecting device 
comprising a casing or other protecting structue for the receptacle and/or 
the magazine, said casing or at least part thereof being shiftable from a 
first position in which the collecting device is used for receiving refuse 
etc, to a second position for providing a sufficient passage or space for 
the removal of the filled receptacle from the collecting device. 
Preferably the magazine is ring-shaped, surrounding a passage through which 
the refuse etc. is thrown into the receptacle. In such a magazine the 
packaging material which is preferably a plastic e.g. polyethylene, film 
is folded together with the folds extending in the circumferential 
direction of the hose. The magazine may be provided at the exterior of 
said casing or within the casing, which is preferably pivotally mounted on 
a supporting structure therefor.

Referring now to the drawings, numeral 1 designates a base plate for 
carrying the refuse bin and forming, together with two vertical columns 2 
mounted on the base plate, a supporting structure or frame for the refuse 
bin. The refuse bin includes a casing 3 which may be cylindrical, e.g. 
circularly cylindrical, in shape. The casing, alternatively, could be 
conically tapering in an upward direction, or have any suitable other 
shape. The casing is made of a rigid material and may consist, for 
instance, of sheet-metal, plastic material, wire netting or the like. The 
casing is open at both top and bottom ends. 
The casing is provided with projecting brackets 4 by which the casing is 
pivoted to the columns 2 by a shaft 5 passed through aligned holes 6 
formed in the brackets 4. 
Disposed within the top portion of the casing is a storage or magazine of a 
hose-shaped flexible packaging material such as a plastic-sheet material 
in an annularly collapsed or folded condition with the folds extending 
circumferentially of the hose. The hose-shaped material is designated by 
11 and the magazine by 12. The hose-material storage is accomodated in a 
cylindrical space between the inner wall surface of the casing and a 
tubular member 7 comprising a cylindrical body portion 8 and a horizontal 
flange portion 9, the latter being supported on a plurality of studs 10 
mounted on the inner wall surface of the casing. From the hose-material 
magazine 12, the hose material 11 is extended across the top edge of the 
tubular member 7 and downward into the casing 3 within which the 
hose-shaped sheet-material will form a receptable or bag for receiving 
refuse. The bag is supported by the inner wall surfaces of casing 3 and, 
as also seen in FIG. 1, there is normally an air-filled space between the 
casing and the bag, this space being adapted to serve as a heat insulation 
to prevent the bag and its contents from becoming excessively heated, e.g. 
when the casing is exposed to intense radiant solar heat. 
In the drawing, the refuse is designated by 13, and it may be pointed out 
in this connection that, owing to the support afforded by the inner wall 
surface of casing 3, the plastic-sheet refuse bag will stand even 
sharp-edged objects, such as thin cans, plastic bottles etc., thrown down 
into the same, without tearing. 
A handle 16 is mounted on the bottom end portion of the casing for 
facilitating pivoting the casing into an upper position in which the same 
is inclined relative to its normal position shown in FIG. 1. FIG. 3 
illustrates the casing when pivoted into such upper or inclined position. 
The pivoting of the casing into its upper position as shown will 
facilitate removal of the filled refuse bag from within the casing. In 
response to such removal, a fresh length of hose material will 
automatically be pulled out from within the storage 12 to form a new 
refuse bag. After removal of the filled refuse bag, the hose material is 
cut off, for instance at the line designated by C in FIG. 3, after which, 
if desired, the refuse bag may be closed at the line designated by A, and 
the hose-material length intended to form the new refuse bag is closed, 
for instance at the line designated by B. The closure of the refuse bag 
and the extended hose material length can most suitably be carried out by 
tieing knots, plastic tapes or clamps or the like. 
As seen in the drawing, the shaft 5 about which the casing 3 is pivoted is 
so disposed that, when swinging the casing upwardly, its bottom end, at 
every point thereof, will move more or less in an upward direction. This 
will enable the bottom edge of the casing in its normal position to 
closely engage the base plate 1 of the supporting frame, thereby 
preventing the refuse bag disposed with the casing from being accessible 
from outside, e.g. by rats or other vermin. 
Designated by 17 is a supporting leg for retaining the casing in its 
upwardly pivoted position. The pivot of the casing may also be placed at 
such a position that the casing remains in its latter position by gravity 
action. 
The refuse bin shown in the drawing would suitably be provided with a 
cover, not shown, which may be detachable or hinged to the casing 3 in a 
conventional manner. 
The hose-shaped plastic-sheet material 11 to form the refuse containers or 
bags may suitable be made of polyethylene which will not leave any harmful 
residues or gases when burnt. 
In the drawing, the magazine or storage 12 is mounted inside the casing 3, 
but, obviously, the magazine 12 could be mounted outside the casing, as 
well. 
The embodiment of FIGS. 4 and 5 comprises a base plate 21 and a vertical 
column 22 mounted on this plate. The refuse bin casing 23 having within 
its top portion 24 a storage or magazine for hose-shaped plastic material 
as described in connection with the embodiment of FIGS. 1 to 3, is 
provided at its bottom portion with a bracket member 25 having a hole 
fitting the column 22, whereby the casing 23 is displaceable along the 
column. In its normal position according to FIG. 4, the casing 23 occupies 
a lower position having its bottom edge 26, defining the bottom opening of 
the casing, closely adjacent to the base plate 21. FIG. 5 shows how the 
casing has been shifted by being displaced upward, thereby spacing the 
casing opening defined by the bottom edge 26 from the base plate 21, so 
that the bag 28 is easily accessible for removal thereof from within the 
refuse bin. The operations of raising the casing and of lowering the same 
after removal of the refuse bin are facilitated by handles 27. 
The invention is not restricted to the embodiments here shown, since these 
are susceptible of various variations and modifications within the scope 
of the invention. 
Thus, where the refuse collecting device is to be placed in a special 
protecting room therefor or the refuse receptacle can be left unprotected 
for other reasons the casing may be omitted or the height thereof so as to 
cover only the magazine. Though, according to the shown embodiments, the 
casing of the collecting device is shiftable in its entirety if is to be 
understood that this is not always necessary, since it may be sufficient 
if part of the casing, for instance the lower part thereof situated below 
the magazine is shiftable in the manner stated. 
The supporting structure for the film magazine holder means may be a frame 
supported from the ground as shown in the drawings but may also be in the 
form of a bracket or the like secured to a wall, pole etc. 
The thickness of the plastic film to be preferably used in the device 
according to the invention can be less than the wall thickness of ordinary 
plastic bags for the same purpose mainly since the receptacle is not 
suspended at its upper edge and since the knots provided on the 
hose-shaped material make possible an even distribution of stressing 
forces in the film. Moreover, where a receptacle protecting casing is 
provided this will lessen the requirements as to the film thickness. 
The collecting device according to the invention can be used for many 
different products, primarily for refuse of all types in private houses in 
the community and in the industry, but also for other products and 
articles of different types for which the collecting device according to 
the invention can serve as a temporary container or storage means.
