10 Claims, 5 Drawing Figures DISPOSABLE FLOOR DISPENSER FOR BIRD CAGE BACKGROUNDOF THE INVENTION Disposable floor dispensers are known, a disposable floor facilitating cleaning of bird .cages. Known dispensers commonly hold a roll of floor-material wound on a reel, the reel being mounted in the dispenser which is fittedexternally of the cage. A portion of the floor material is unwound from the reel and passes through a wall of the cage, extends across the cage leaving the cage'at an opposite wall either to be wound on a further reel, or to be disposed of. Priorart dispensers are commonly relatively large, comparedto the cage itself, are fitted externally of the cage, and often they cannot be adapted easily to an existing cage.

SUMMARY OF THE INVENTION I The invention contemplates a floor dispenser that can be fitted within a cage without structural modifications to the cage. The dispenser houses a roll of floor material mounted on a spindle, outer ends of which are secured in walls of the cage,

A lower edge of a side member of the dispenser has a resilient,

DETAILED DISCLOSURE FIGS. 1 and 2 A common bird cage 10 has a roof 11, front and

rear side walls

12 and 13 and right hand and left hand end walls and 15. Flanged

end plates

16 and 17 are provided adjacent the end walls 14 and and extend upwards from a base 18 of the cage. The base 18 has short upwardly extending flanges designed 19 through 22, which accept lower edges of the walls 12 through 15, which walls are of ordinary bird cage wire grill construction.

A dispenser or accessary 24, according to the invention, for a disposable floor has a top cover 25' and a side member 26, the dispenser extending between the

side walls

12 and 13 and being fitted at one end of the cage, adjacent the end wall 15. FIG. 3

The dispenser 24 contains a roll 27 of disposable floor material, an unrolled portion of which is designated 28, and

extends between the flanges 19 through 22 (FIGS. 2 and 3) with an outer end 30 projecting beyond the flange as shown. The floor material can be paper which will absorb moisture to some extent, or can be a flexible plastic sheet. The floor material lies on a slidable floor tray 31, the end 30 passing through a gap 29 between the floor tray and the flanges 20. The tray 31 has peripheral bent-up edges, 31.1 through.31.4, three only being shown in FIG. 3.

The roll 27 is mounted on a spindle 33 supported at its ends by portions of the wire grill of the side walls, later described with reference to FIG. 4. The spindle serves as a means to mount the roll of disposable floor material permitting unrolling of floor material from the roll.

The cover of the dispenser has a flange 35 projecting downwardly from an edge 34, and is held adjacent the flanged end walls 17 of the cage by a magnet 36. Two magnets can be used to hold the cover 25, one at each outer end. An edge 38 parallel to the edge 34 projects beyond the side member 26 forming an eave which protects the roll 27 from bird droppings and other foreign matter.

The side member 26 has an upper edge 40 adjacent the cover 25, and a lower edge 41 spaced from the floor 31 by a distance 42, of the order of half an inch. A flexible flap 43 extends downwards from the edge 4] bearing against the floor "31. The floor material 28 is unwound from the roll 27 and passes between the flap 43 and the floor 31. The flap is urged against the floor material with sufficient force to prevent inadvertent unrolling of the roll and to produce a drag on the floor material as it is unwound, unwinding being effected by pulling the end in a direction shown by an arrow 32. The side member 26 is held in place by means later described. FIGS. 4 and 5, with references to FIG. 3

To facilitate fitting of the roll 27 and to reduce soiling, a carton 51 can be used to contain the roll. The carton. is generally square in section and encloses the roll, a closed end 52 of the carton being provided with a hole 53 to accept an outer end 55 of the spindle 33. A longitudinal slot 54 (broken outline) in a lower wall 57 of the carton, permits withdrawal of floor material from the carton.

The end 55 of spindle 33 has a diametric slot of sufficient f width to accept a cage wire element 58 of the side walls 12, the slot being similar to that of a common perch. An opposite end of the spindle protrudes similarly from the carton, the spindle 33 being jammed between opposite sidewire of the cage.

When using a carton, an alternative side member 60 is used in the dispenser. The member 60 has an upper end edge 61 extending outwards of the walls of the cage and a cut-out portion 62 forming a tongue 63. The member 60 has a lower edge 66 spaced above the tray 31, similar to the edge 41, and a flap 64, similar to the flap 43, both as described in FIG. 3. An end edge 63;] o1 the tongue 63 is held adjacent an inner face of the flange 19 as will be explained. An opposite end (not shown) of the side member 60 has a similar end edge, a cut-out portion, andtongue. When the side member 60 is fitted as shown in FIG. 5, the cut-out portion 62 accepts a protruding lip 65 of the flange 19. Spacing between end edges of the tongues of the member 60is somewhat greater than spacing between inner faces of the inner flanges 19 and 22 so that, when fitted, the side member 60 is bowed slightly, which bowing increases effective stiffness of the member 60 The tray 31 (FIG. 3 only) has the peripheral bent-up edge 31.] at an end of the tray external of the cage and the edge 31.3 at an opposite end having an upper edge 73. When the tray 31 is withdrawn from under the member 60 the upper edge 73 clears the lower edge 66 of the member 60, and the flap 64 bends upwards to permit the lip 31.1 to pass. Bending the flap 64 tends to produce. an upward force on the flap 64, which upward force is restricted by the tongue 63 being forced against the lip 65.

The member 60 is bent to produce a horizontal step 67 which carries the lower wall 57 of the carton, supporting the carton above the tray 31, to provide clearance for the upper edge 73 of the lip 71, when inserting or withdrawing the tray. The step 67 also prevents rotation of the carton, the carton tending to rotate in a direction of an arrow 68 when floor material is withdrawn from a roll. The tendency above produces a downward force on the side member 60 being resisted by the lip 65.

Thus vertical movement of the member 60 is restricted by the lip 65 in the cut-out portion 62. Horizontal movement of the member 60 is restricted by the carton and a wire element 70 of the cage side wall, which element is held adjacent the side member 60.

The side member 26 (FIG. 3) has similar end edges, cut-out portions and tongues (not shown). However the step 67 of the member 60 is not required on the member 26 as the roll is fitted without a carton, the roll 27 hanging freely and being free to rotate. Any drag occuring during unrolling is reduced, the roll requiring support only from the spindles jammed between the side walls.

OPERATION To fit the roll of floor material into the dispenser, the roll is threaded onto the spindle and the spindle is jammed between the side walls of the cage at the position as shown. The side member is elastically deformed slightly to fit between the flanges 19 and 22, and the cut-out portions accept the protruding lips. If a carton is used, the lower wall of the carton rests on the step 67 of the member 60, otherwise the roll 27 hangs freely as in FIG. 3. The portion 28 of the floor material is unrolled under the flap 43 and spread across the floor tray 31, the outer end 30 extending through the gap 29 between the floor 31 and the flange 20. The top cover 25 is placed on top of the side member, the magnets 36 holding it against the end wall 15. The cage is now ready for use.

When the portion 28 of the floor material is soiled, it is replaced by gripping the end 30 to the edge 31.3 and pulling the tray, and with it the floor material, in the direction of the arrow 32. Unsoiled floor material is unrolled from the roll, sliding under the flexible flap, which produces a drag on the floor material. The edge 31.1 of the tray passes under the flap, and the tray is withdrawn completely from the cage, relative positions of the tray and soiled floor material being substantially unchanged.

The soiled portion of the floor material is removed and the tray reinserted into the cage, passing underneath the unsoiled portion of floor material. The edge 31.1 bends the flap as it passes underneath, the tray being slid into operative position. Thus, when operative, a length of unsoiled floor material extends from the dispenser to the edge 31.3 of the tray, forming a clean floor.

When the carton is used, it rests on the step 67, little difficulty being experienced in reinserting the tray under the dispenser. If no carton is used, the roll of floor material hangs freely, being easily displaced by the edge 31.1, permitting insertion ofthe tray.

ALTERNATIVES AND EQUIVALENTS As described, the dispenser 24 has two elements, namely the top cover 25 and the side member 26. A two-element dispenser is more adaptable than a one-element dispenser if the dispenser is to be used with more than one type of cage where there is likely to be dimensional differences between cages. If the elements are made ofa relatively soft plastic, it is generally quite easy for an owner, with a small amount of modification, to fit a dispenser to a particular cage.

However, if the dispenser is to be used in one size of cage only, a one-element dispenser can be used, that is the top cover 25 and the side member 26 are integral, dispensing with the eave as formed by the edge 38.

Means alternative to the magnets can be used to secure the dispenser to the cage, for instance clips moulded in the top cover and adapted to fit around elements of the walls of the cage. The particular means of securing the housing inside the cage is immaterial to the invention, as is the number of elements from which the dispenser is made.

If the side member is made of a suitable flexible material, the flexible flap can be integral with it: or the flap can be made of a strip of sponge-like material. Any flap similar to the above, which can be urged against the floor to produce a drag on the floor material, and that can be displaced upwards by the edge of the tray, serves as a means to reduce inadvertent unrolling.

The roll 27 is wound anti-clockwise, that is, the portion 28 extends from a right hand side of the roll as seen in FIG. 3; when the roll is unwound, the carton has a tendency to rotate clockwise as above, and to be pulled downwards onto the tray. The step 67 serves as a means to hold the carton clear of the tray 31, and as a means to prevent rotation of the carton in the direction of the arrow 68 (FIG. 5), when the floor material is pulled from the roll. Other means to hold the carton clear of the tray and to prevent rotation are known, such as pegs (not shown) protruding inwards from the side member 60 in which instance the step 67 can be eliminated. With this alternative, the side member 60 would be similar to the side member 26, but would have pegs as described.

Many common cages are fitted with a slidable floor tray to facilitate cleaning, the tray having peripheral bent-up edges as described. With this type of tray, if the tray is not withdrawn concurrently with the floor material, particulate matter on the disposable floor would be trapped by the edge 31.3. With some cages, a flat tray is fitted, peripheral bent-up edges being eliminated, and with this type of tray, the soiled floor material can be withdrawn through the gap 29 whilst the tray remains in the cage, particulate material being fed out of the cage on the soiled floor material.
