Feb. 19, 1957 w. L. PAUL DUST BAG AND STAND FOR MQPS Filed May 22, 1953 2,781,536 DUST BAG AND STAND FOR MOPS Wanda L. Paul, New York, N. Y. Application May 22, 1953, Serial No. 356,632
1 Claim. (Cl. 15-104 This invention relates to dust bags and holders therefor and more particularly to bags adapted to enclose a mop while the latter is shaken.
One object is to provide a container in which a mop may be shaken to free it from dust and which will confine the dust to a small space.
Another object is to provide a simple stand for said container and which may be folded to a compact form for storage when not in use.
Another object is to provide said container with a removable component wherein the dust will accumulate in a more or less compact mass.
To attain these objects and other objects that will be appreciated as the description proceeds, I employ a stand having two pairs of legs, the two pairs being connected by toggle members which members are so attached to the leg pairs that stability of the stand is obtained. Depending from the upper part of the stand is a bag selectively covered by a pair of half-doors between which a mop handle may pass.
Fig. 1 is a perspective of the bag and erected stand;
Fig. 2 is a side view of the assembly of Fig. 1 shown in collapsed condition;
Fig. 3 is a plan of the bag and erected stand;
Fig. 4 is a fragmental side view of the stand;
Fig. 5 is a perspective of the bag as assumed when the stand is erect;
Fig. 6 is a fragmental side view of the lower end of the bag and associated parts;
Fig. 7 shows a modification of the parts of Fig. 6;
Fig. 8 is a side view of a modification of the bag;
Fig. 9 is a plan of the bag of Fig. 8; and
Fig. 10 shows details of the bag of Figs. 8 and 9.
The invention comprises a stand 10 having four in- Wardly'leaning corner legs 11, the front and adjacent pair each being secured fast together respectively by lower and top rungs 12 and 14 to form front and rear stand sections 15 and 16. The sections 15 and 16 are connected to each other at their lower ends at each side by toggle strips 18 and 18a pivoted together as at 19 and to the respective legs of the sections as at 20 and 21. Upward motion of the zone of the pivot 19 is permitted as in Fig. 2 but downward motion slightly past straight line alinement is prevented by a stop hook 22 on an extension 24 of the strip 18.
The upper ends of the sections are connected together in a somewhat similar fashion but with certain important details added to impart rigidity to the stand as described below. The inner faces of the legs of the two sections 15 and 16 are smooth as at 25 and are adapted to be engaged by the end faces 26 of a toggle bar 28, 28a which in substantially horizontal straight condition abuts snugly against said faces 25.
The bar is fastened to the two sections by hinges 29 under the bar at the faces 26. The height or depth of the bar, when in raised position as in Fig. 4, prevents further angular motion between the leg and the elevated bar and so imparts rigidity to the stand. The bar breaks 2,781,536 Patented Feb. 19, 1957 at its middle at a hinge 30 on the top face of the bar, the two inner ends being adapted to abut each other as at 31 Fig. 4 when in erected position.
The above described construction permits the bar 28, 28a to break downwardly with nothing mentioned thus far to hold it erected. The bar is held erected by means of a toggle lock 32 on the outer face of the bar and adapted to break upwardly and having its arms pivotally mounted on the bars 28, 28a as at 34 and 35. Downward movement of the lock'past alinement is prevented by means 36 similar to stop 22. I
A square dust bag 38 of flexible material such as cloth hangs within the legs, top rungs and bars by suspension straps 39 and 40 folded over the bars and rungs respectively and having snap fasteners 40'. Lower straps 41 on the bag passing around the legs and through staples 42 keep the bag distended.
The bottom of the bag is provided with an opening 43 having an elastic or drawstring 44 constricting the opening over a funnel member 45 having a long bayonet slot 46 in the stem 48 thereof. A dust receiving can 49 is fitted onto the stem and held thereon by engagement of a detent 50 in the slot.
The stand is covered by a pair of mating half doors or lids 51' each provided with hinge hasps 52 hooked or looped over the top rungs 14 between the straps 40. The inner margin of each door is provided with a semicircular opening or slot 54 and the marginal portions are long enough to extend over the bars 28 and 28a.
In another form of the invention as shown in Fig. 7 a funnel member 45' may be provided with a threaded stem 48 for holding a fruit jar 49'.
In still another form of construction the bag may be spherical as shown at 38' Figs. 8, 9, and 10 and provided with large slit 51 at the top or near the pole opposite the member 45'. The material of the bag 38' may be stilfened to preserve it in distended form as shown, though this is not entirely necessary as explained below.
A semi-circular bushing 52 having inner and outer flanges 52a, 52b is let into the marginal portion 54 of each side of the slit and shown upwardly turned in Fig. 10 and a half ring 55 applied to the portion to clamp same against the bushing to provide a half neck to the bag. The bushing 52 and half ring 55 are held together by fingers 56. Two of such devices form the whole neck.
If desired the funnel stem member may be connected to a hose member of a vacuum cleaner (not shown) to draw a current of air through the bag. The bag 38 need not be supported but may be held in the hand by the neck made up of the bushings 52. If a vacuum cleaner is connected to the stem 48' the bag will tend to collapse but this increases air velocity past the mop if the latter is within the bag. Alternate shaking of the mop and the use of the vacuum is a satisfactory operation.
In all forms of the invention a mop head may be inserted into the bag and the latter substantially closed leaving the handle protruding whereby the mop may be shaken vigorously without danger of dust escaping into the general atmosphere.
I claim as my invention:
A dust receptacle and collapsible mount therefor comprising a stand having four inwardly leaning corner square legs; upper and lower rungs securing the front pair of legs together to form a front section and similar rungs forming a back section; upwardly breaking toggles connecting the lower parts of the sections together; downwardly breaking toggle bars joining the upper portions of the sections together, the ends of the bars when the latter are in substantially straight horizontal distended position snugly abutting against the legs; locks for maintaining the bars in straight position; a dust bag the bounds of the upper ruhgsand bars; straps seeured to the upper margins of the bag and disposed over the rungs and bars for suspending the bag therefrom; apairof lids each covering about half the Bag and hinged" on respec- 5 tive upper rungs, the free marginal portions oi the lids meeting and each provided with a. semi-eircu larwslot to provide a round hole adapted to receive a mop handle;
a funnel member in the bottom portion of the bag and having a stem portion opening therebelow, and a eol1ect- 10 ing vessel removably secured to said stern portion.
