Abstract
A vacuum waste collection system is provided with an under-the-counter receptacle that can be used to remove dust, etc., that is swept into it. The door on this receptacle is spring loaded so that it opens by contact from a foot, making it unnecessary for the householder to bend over to use the system.
Description
_ 2 _ This invention relates to a receptacle for receiving waste that does not entail the transport of the normal hose and wand tools to the site being cleaned.
Suction pick up devices to receive sweepings from a floor are known. For example, there are three prior patents to an inventor Bierstock, namely Canadian patents 642,539, 670,879 and 675,552. The first two patents relate to suction devices for use with cannister vacuums and the third comprehends central vacuum systems. Patent 670,879 shows a number of nozzle embodiments , many of which move into the room in use .
In Figures 1 to 5 a stationary device is shown, but this version does not include a seal when not in use.
In patent 642,539, no stationary devices are taught. A valve structure is provided at the outlet, which can be moved between three different positions by manipulation of a toe-operable handle 326. When the device is not in use the valve is open. To use the device the valve is slid to one side, with the vacuum on, which seals the outlet. This causes the nozzle 202 to extend outwardly. When finished the valve is slid to the other side, sealing the outlet but causing the nozzle to retract. The extension and retraction is accomplished by a series of tubes which preferentially direct the vacuum.
Patent 675,552, teaches using the moveable nozzle with a central vacuum source. However, in this design the nozzle extends and retracts by means of an electro-mechanical actuator. A valve, to close the outlet is taught. The valve is opened and closed in response to the movement of the nozzle by the actuator.

Description of the Preferred Embodiments In Figure 1 a hose 1 leading to a central vacuum suction system (not shown) terminates at a nozzle box 2 that converts the shape of the passageway for air flow (shown by arrows A) from a rectangular to a circular shape. The nozzle box 2 has side walls 2a, a base 2b and a roof 2c; in this sense the nozzle box is a prefabricated unit which is sized and shaped to be simply and easily placed in an aperture in a wall of a building as shown in the Figures. The hose 1 terminates at a circular hose outlet end 3 of the nozzle box 2 with a sealed joint . As shown in Figures 1, 2 and 3 , the outlet is above floor level in this embodiment. A
rectangular end 4 of the nozzle box 2 provides an opening or orifice 5 that serves as an inlet for dust and waste. The dimensions of the rectangular orifice 5 are selected to maintain high speed air flow when the vacuum collection system is operating e.g., the cross-sectional area of the inlet and outlet orifices is on the order of that of a cross-sectional area of the hose 1.
While the inlet orifice 5 may be of a limited height vis: 3/4 inches high with a width of 10 inches, it is preferably set in a frame or box 6 that extends upwardly to a height of , for example : 3 inches , above the bottom of the orifice 5. This frame 6 serves to support a hinge 7 for a door 8 which serves as one form of closure for this receptacle. It also contains an electrical contact switch 9 and a door latch receptacle 10 whose functions are described subsequently.
The nozzle box 2 and frame 6 are preferably immovably mounted in the rear wall of the kick space 11 located under a typical kitchen counter 12 adjacent to a floor 15. Mounting holes M are shown in Figure 3.
Once the nozzle box 2 is mounted at floor level beneath the counter 12, the door or closure 8 may be attached by spring-loaded hinges 7 to the frame 6.
The hinges 7 may be attached to either the left or right side of the frame 6 to provide for it to swing open about a vertical axis on either side of the orifice 5.
The door 8 carries a gasket 13 (shown in dotted outline in Figure 2) to assure an air tight seal of the orifice when the door 8 is closed. Alternately, the gasket may be mounted to the nozzle box 2 as shown as 13' in 5 Figure 2. In either case gasket 13 or 13' is mounted so as to form an airtight seal between the closure 8 and the nozzle box 2 when the closure 8 is in the closed position. This gasket 13 or 13' ensures that the vacuum in the attached hose network is not degraded when this trash receiver is not being used.
Beneath the door 8, a sloping chamfered edge 14 is preferably provided in the event that the bottom edge of the orifice 5 is not aligned with the floor 15.
This chamfered wedge 14 leading up to the orifice 5 may be part of the frame 6 or can be attached separately after the nozzle box 2 is installed in the kick space 11. The sloped edge 14 directs waste from the floor surface up to the opening to permit said waste to be drawn through the opening by the suction from the central vacuum suction system.
The door 8 carries a foot contact latch 16 which engages with a complementary door latch receptacle 10. This latch 16 is of the type that will release when contacted or tapped, as by a foot. The hinge 7 for the door 8 is preferably spring-loaded by a spring 17 which acts to swing the door 8 open about the vertical axis when the latch 16 is released and to hold the door in the open position against the air flow as shown in Figure 2. The door latch receptacle 10 may be made adjustable in its position and orientation to accommodate the reversal of the latch 16 when the door 8 is converted from left to right side opening.
The door 8a may alternately be hinged to swing upwards as shown in Figure 7. In this configuration the nozzle box 2a is installed forwardly of the rear wall 18 of the kick space 11 and above the floor 15 and is modified to provide a downwardly directed hose connection at 3a which penetrates the floor 15. A
baffle plate 17 helps direct waste downwardly through, for example, a 2" vacuum connector.
In operation, a user who has collected waste on the floor as by sweeping need merely press against the contact latch 16 to open the door 8. The electrical contact switch 9, previously held in an "off" position by the door 8 in its closed condition, is released by the opening of the door 8 and switches to an "on"
condition. This starts-up the motor in the central vacuum cleaning system to produce a suction through the orifice 5. The waste is then directed to the orifice 5 where it is removed by the air flow A. When finished, the closure 8 is pushed closed by the user.
Another alternate variation of the invention shown in Figures 8 and 9 utilizes the standard portable vacuum cleaner 18 as the suction source. Conveniently, this unit is stored in a cupboard or cabinet proximate to the waste receptacle as, for example, under a counter 12. It is stored with its normal hose 19 connected to a pipe 20 leading to the nozzle box 2. It is also stored with its electrical plug engaged in a power outlet controlled by the power switch 9, or by a wireless switching control 20.
In this manner, the normal vacuum cleaner, while in storage will serve to operate the waste receptacle outlet of the invention.
The foregoing has constituted a description of specific embodiments showing how the invention may be applied and put into use. These embodiments are only exemplary. The invention in its broadest, and more specific aspects, is further described and defined in the claims which now follow.
These claims, and the language used therein, are to be understood in terms of the variants of the invention which have been described.

condition. This starts-up the motor in the central vacuum cleaning system to produce a suction through the orifice 5. The waste is then directed to the orifice 5 where it is removed by the air flow A. When finished, the closure 8 is pushed closed by the user.
Another alternate variation of the invention shown in Figures 8 and 9 utilizes the standard portable vacuum cleaner 18 as the suction source. Conveniently, this unit is stored in a cupboard or cabinet proximate to the waste receptacle as, for example, under a counter 12. It is stored with its normal hose 19 connected to a pipe 20 leading to the nozzle box 2. It is also stored with its electrical plug engaged in a power outlet controlled by the power switch 9, or by a wireless switching control 20.
In this manner, the normal vacuum cleaner, while in storage will serve to operate the waste receptacle outlet of the invention.
The foregoing has constituted a description of specific embodiments showing how the invention may be applied and put into use. These embodiments are only exemplary. The invention in its broadest, and more specific aspects, is further described and defined in the claims which now follow.
These claims, and the language used therein, are to be understood in terms of the variants of the invention which have been described. They are not to be restricted to such variants, but are to be read as covering the full scope of the invention as is implicit within the invention and the disclosure that has been provided herein.
