Abstract

A support frame for a flexible refuse receptacle comprises a first frame portion 16 having brackets 12 for mounting the support frame on a trolley, wall or upright frame. A second frame portion 17 is movably attached to the first frame portion 16 by means of screwing bolts 9 and nuts 10. The second frame portion is attachable to the first frame portion at various positions so as to adjust the size of the aperture formed by the two frame portions for receiving the flexible refuse receptacle. The second frame portion is pivotable relative to the first frame portion for ease of attachment of the flexible refuse receptacle to the frame; the flexible defuse receptacle being held relative to the support frame by a friction fit therebetween. <IMAGE>

Description

SPECIFICATION Easy-stretch-bin This invention relates to a domestic (or industrial) refuse container Refuse containers are well known to everyone, and are made in many shapes and sizes, most of which have some form of lid or cover, they can stand upright on the ground, or either secured to wall, or as a trolley with wheels to enable it to be pushed around. The refuse container described as EASY-STRETCH-BIN, consists of a rectangular shaped lid which is hinged to a supporting "S" shaped brackets, these brackets in turn are attached to a solid steel bar rectangular "L" shaped each end, the full rectangular shape in turn supporting a plastic (or other material) bag. Being of simple construction, the manufacturing cost is much lower than other refuse containers and easier to make, therefore less expensive to purchase.

According to the present invention, there is a rectangular steel bar frame half of which is "L" shaped, and the other half is "U" shaped steel bar. The two halves are joined together by means of a bolt each side, back and front of the frame, enabling the "U" shaped steel bar to move freely up and down, whereas the "L" shaped supporting bar and frame remains stationary. This enables a plastic bag or the like to be fitted easily when the movable bar is sufficiently raised, then folding the bag outwardly and over the bar steel frame, and then pulling back the "U" shaped movable frame into the horizontal position, this stretches the rim of the bag very tightly and firmly, preventing the bag from falling away from the frame, and likewise supporting easily the refuse contents in the bag which is hanging from the steel frame bar.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1. shown in perspective, a top elevation, showing lid and hinges, the front and side of supporting bar, and an "S" bracket which attaches the unit to a wall or stand.

Figure 2. Illustrates the underside elevation, showing the complete supporting steel bar which holds the bag (not shown) to which are attached the "S" bend brackets which supports the whole unit when fixed to wall or stand, the lid is shown in background, and the two bolts supporting the "U" shaped movable steel bar.

Figure 3. shows the rear side of the unit, showing the i'S" bend brackets for ataching to a wall or stand, attached to which are the "L" shaped steel bar and the "U" shaped steel bar the latter is attached by means of two bolts, one at the back as shown in drawing, and the other is in front (not shown in this drawing) Figure 4. Illustrates a side elevation in a horizontal position showing the "S" bend attached bracket to the supporting steel bar, showing the two bolts for the movable "U" steel bar, also showing an attached bag, and lid and hinges.

Figure 5. This is a slightly enlarged section of the supporting bar steel frame, showing the method by which the "U" shaped steel bar is attached to the main "L" shaped steel bar frame, the latter is in a fixed position, whereas the former is movable. The position of the fixing bracket is shown for attaching to a wal or stand. A bag with a smaller or larger aperture can be fitted to the bar steel frame whereby the ends of the movable "U" shaped arm is extended each side, and a number of extra clearance holes are drilled in it, by means of this, the securing bolts holding the "U" shaped movable steel bar can be adjusted to take a smaller or larger bag, as shown in the drawing.

Figure 6. This shows an exploded part of the securing nut and bolt which holds together the "L" shaped stationary steel bar and the attached "U" shaped movable shaped steel bar, it will be seen that the latter has a clearance hole, allowing free movement of the "U" shaped steel bar, either up or down.

Refering to the drawings No.2335, Figs. 1 to 6. giving full details. According to the size of the refuse containing unit, ligher or heavier material may be used, such as steel or any other suitable material for either the bag frame support or the "S" bend supporting brackets.

The "S" angled supporting brackets are preferably welded to the "L" shaped nonmovable part of the frame shown in Fig. 4. of sections 11, 12, 14, and 15, The "S" angled brackets, two of which support the frame, these are shown supporting the "L" shaped section in Fig. 3, 4, and 5, of sheet Nos. 1, and 2, sections 12, 14, 16, and 25, also section 18, allows the lid together with section 15, to stand approximately 25.MM. away from the wall. The section 18, shown in Fig.

4, is off-set about 6.5, MM. from the wall, the top of which supports the hinge and lid, section 20, and 21, shown in Fig. 1. of No.1.

sheet.

The frame itself consists of two separate parts, there is the "L" shaped steel bar section 16, of Fig. 5, which is the non-movable part that is rigidly attached by welding to the two of the units supporting "S" bend steel brackets, sections 12, 14, 15 and 18, of Fig.

4.

The movable steel bar section 17, of Fig. 5, is shown in a semi upward swing from the horizontal position, also sections 24, of Fig. 5, shows a number of clearance holes drilled at the open ends of the steel bar section 17, in Fig. 5, this enables, the securing bolt 9, shown in Fig. 6, to be removed from each side of the unit, and then replaced in other holes required in order to enlarge the size of the aperture of the rectangular steel bar unit, or likewise decrease its aperture, enabling smaller or larger bags to be fitted. It is preferable for the purpose of economy to have only one single hole each side of section 17, with bolt 9, of Fig. 5, as a standard unit.

The "U" shaped steel bar section 17, of Fig. 5, is attached by means of bolt 9, together with 19, washers, into the threaded part of 16, and 23, through the clearance hole of 24, and the locking nut 10, securing the assembly securely to 16, sections shown in Figs. 5, and 6.

This allows a plastic bag, or any other suitable material, to be placed through the centre of the steel metal bars sections 16, and 17, with the latter movable arm raised upwards to approximately 45 degrees, the open end of the plastic bag can then be folded outward and over the edges of the steel bar frame 16, and 17, sections for approxibately 25-30, MM. When the correct size plastic bag, and of course the correct texture and thickness, using the movable steel bar 17, section, the latter steel arm may be pulled down to the 180 degrees horizontal position thereby stretching the bag very firmly at its open end, easily holding the weight of a normal dustbin load.

It will be seen that by this method that the movable arm section 17, moves freely because of the clearance hole drilled at section 24, Fig. 6. but when the bag is stretched by the arm 17, being pulled down it holds firmly in the horizontal position. The lid section 21, shown in Fig. 1-4, can be made of any suitable material, but preferably steel or mirrored finished stainless steel. The "EASY-STRETCH BIN" unit can be attached either to a wall, onto a stand, or as a trolly on wheels. Removing the bag shown in section 22, Fig. 4, is very simple indeed, the arm of section 17, shown Fig. 3, and 5, is raised from the 180 degrees horizontal position, to approximately 45 degrees position, illustrated by section 17, in Fig. 5. Referring again to the lid shown in section 21, Fig. 1-4, it will be seen that the lid 21, overlaps the unit steel bar frame, in this instance by approximately 20-30, MM.

shown in Fig. 2, this allows easy access to the aperture of the bin, and also protects rain from getting into the interior of the bin. The width of the overlapping lid section 21, shown in Fig. 2, will vary according to the size of bag. unit held by steel bars-frame in either smaller or larger size units, making the interior of the plastic bag 22, completely weatherproof.
