DESCRIPTION:
BRIEF SUMMARY
This invention relates to a suspension rack for bags and sacks, in particular refuse disposal bags for domestic purposes, comprising a circumferentially discontinuous carrier which is substantially horizontal in the position of use and is adapted to engage an everted or folded portion of the bag at its open end and to secure the bag by stretching or distending said portion.
The most widespread racks of this type are made from plastic coated wire forming both said carrier and a support for the bag bottom and, moreover, a pair of braces connecting said carrier and said support, the braces comprising eyes to be used when fastening the rack, for instance on a kitchen cupboard door. The carrier forms a substantially rectangular frame with a gap in the fowards facing side so as to present a pair of somewhat yielding wings distending the bag opening approximately into the same rectangular shape.
Filling the bag with kitchen refuse is generally done at some or many times and it may therefore be desired that the bag is kept closed between the individual fillings. For this purpose a flap cover is applicable which may be mounted on the suspension rack or possibly directly on the kitchen cupboard door. However, such a cover cannot be expected to shut tightly odourless on the suspended bag and requires, moreover, an extra manipulation when disposing a portion of refuse.
To eliminate such drawbacks a more complicated suspension rack has been developed which instead of a yielding carrying frame is provided with a pair of jaws with pins to engage perforations in the bag sides. Said jaws may be moved towards and away from each other--either manually or automatically by closing and opening the cupboard door on which the rack is mounted--and are thus able to keep the bag closed between the fillings by squeezing its mouth together. From consumer's point of view this rack suffers, however, from the inconvenience that it requires special bags that are not alone of a given size (the same applies to the first mentioned rack), but which must further be provided with perforations at the mouth in order to be hooked on the jaws.
The present invention provides a suspension rack that is not only adapted to efficiently keep the suspended bag or sack closed between the fillings by squeezing its mouth portion together, i.e. without the use of an extra cover, but which may as well be used for bags or sacks of varying size and without particular suspension measures, such as perforations in the bag wall.
This has been achieved in that the said carrier comprises two opposed, scissorslike holders, the limbs of which are movable between an open, V-like position in which they distend the mouth of the bag into rhomboid shape, and an assembled position in which the mouth or top portion of the bag while still being stretched is kept closed by collapsing.
In this case the fastening of the bag or sack is--as for the first mentioned rack--effected by distending or stretching its top portion which is a condition if said special suspension measures of the bag shall be avoided, but while maintaining the stretching effect the said holders can further open and close the bag, thereby saving an extra cover.
To ensure an efficient fastening of the bag or sack it is according to the invention preferred that the two holders are displaceable towards and away from each other and spring-biased in the last mentioned direction to ensure the stretching of the top portion of the bag.
The fact that the carrier is constituted by two holders entails the particular advantage that one and the same rack may be used for bags or sacks within a great variety of sizes, namely by providing the two holders in a respective one of two brackets mounted on a common base, said brackets being spaded adjustably apart. If the rack is associated with a support for the bottom of the bag or the sack, such support should also be adjustable according to the size of the bag, in particular to its height.
