Definitions

• 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 forwards facing side so as to present a pair of somewhat yielding wings distending the bag open ⁇ ing approximately into the same rectangular shape.
• a flap cover is applicable which may be mounted on the suspension rack or possibly directly on the kitchen cupboard door.
• 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.
• 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 with ⁇ it particular suspension measures, such as perforations in the bag wall-
• 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.
• 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 stretch- _; ing effect the said holders can further open and close the bag, thereby saving an extra cover.
• the two holders are displaceable towards and away from each other and spring-biassed 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 spaced 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.
• Fig. 1 illustrates the embodiment in a perspective view
• Fig. 2 the left part of the rack in Fig. 1, seen from above and substantially in section.
• the illustrated rack is designed so that bags for kitchen refuse can be suspensed thereon and it comprises a mounting plate 1 to be fastened with screws on a vertical surface, for instance on the inside of a cupboard door.
• the plate carries two brackets 2 and 3, at least one of which being preferably adjustable along the plate as indicated by the double-arrows 4 so as to adjust the distance between the said two brackets according to the size of the bag to be suspended.
• the two brackets may be alike as to structure, but symmetrically designed, and their details appear from Fig. 2.
• the bracket comprises a box- shaped housing 5 accommodating a supporting arm or lever 6, appropriately made from spring steel, provided with a bushing 7 at its one end while its other end engages a slit in the rear wall 8 of the housing, said rear wall being secured to the mounting plate 1 in a
• the arm or lever 6 can be pivoted somewhat to the left by rotating a spindle 9 by a handle 10.
• Said spindle 9 is accommodated in the side walls of the hous- ing 5 and retained against axial displacement by means of a pair of stop rings 11.
• the spindle carries a cam 12 -which is fixed to the spindle so as to rotate therewith and presents a cylindrically arched abutting surface 13 for a loose cam 14 provided with a projection 15 having a non-circular cross-section and extending through an oblong hole 16 in the support ⁇ ing arm. or lever 6, thereby preventing the loose cam * from rotating about the axis of the spindle 9.
• a pres ⁇ sure spring 17 urges the lever rod against the loose cam 14, which is thereby at the same time urged against the cam 12.
• a rotational movement of the spindle 9 and .thus also of the cam 12 consequently results in a dis ⁇ placement to the left of the cam 14 bringing along the lever 6 by pivoting it about the bearing point at the ' rear wall 8 of the housing.
• the lever may simultaneous ⁇ ly be displaced a little at the bearing point so as to allow the bushing 7 of the lever when swinging to follow a straight line instead of a circular arc.
• the abutting surface 13 between said two cams 12 and 14 need of course not be cylindrically arched as it may as well be roof-shaped or plane and form an angle different from 90° with the axis of the spindle 9.
• Either of the brackets 2 and 3 accommodates a holder consisting of two pieces of bar material, forming alto- gether a pair of tongs or scissors with two limbs 18 and 19, 20 and 21, respectively.
• the two associate limbs are integral with a respective one of two vertical bar sections 18a, 19a which extend downwardly through a guide slit 22, Fig. 1, in the upper wall of bracket housing 5 and are journalled in laterally abutting rela ⁇ tionship in the aforementioned bushing 7, beneath which said sections continue into control levers 18b and 19b pointing towards the ends of the bracket housing 5 and resting on its bottom.
• control levers 18b and 19b engage inclined guide slots 23 and 24 at the bottom of the housing so that the control levers convert the dis ⁇ placement of the bushing 7, referred to above, into a rotation of the bar pieces, thereby swinging the limbs 18 and 19, 20 and 21, respectively, from the open position as shown in Fig. 1, towards each other to the assembled or collapsed position shown in dotted lines in Fig. 2.
• a bag can be suspended in the same way as is the case with ordinary racks with a frame-shaped carrier, the top edge of the bag being everted or folded over the limbs 18-21, following which, the top of the bag is kept stretched and distended approximately in rhomboid shape.
• the handle 10 and thus also the spindle 9 common to the two brackets 2 and 3 are rotated through an angle of less than 90 , so that the two scissors- or tonglike holders 18,19 and 20,21 are folded up and displaced as explained above, thereby closing the mouth of the bag.
• the edge portion of the bag shall then remain in a stretched position which according to the illustrated embodiment is ensured by moving the ends of the four limbs 18-21 pependicularly to the connecting line between the vertices of the two holders, as indicated by the arrow 25 in Fig. 2.
• the said rotation of the spindle 9 may be effected manually, but in case the rack is mounted on a cupboard door the rotation may as well be effected automatically when opening and closing the door, the handle 10 being then adapted to engage and disengage an operating member designed and mounted in an appropriate manner.
• the handle may be connected with a pedal.
• Fig. 1 illustrates parts of a pair of vertical rack braces 26 supporting a support, not shown, for the bag bottom. As mentioned above such a bottom support may as well be adjustable according to the size of the bag.
