This invention relates to smokeless ashtrays and more particularly to ashtrays which stay cleaner than conventional smokeless ashtrays and which have filters that are easier to replace than on conventional smokeless ashtrays.
An example of a smokeless ashtray is found in U.S. Pat. No. 4,671,300. As with the inventive ashtray, the patented ashtray uses a filter to create the smokeless effect. However, in the ashtray of U.S. Pat. No. 4,671,300, the chore of replacing the filter requires a minor amount of dismemberment of the ashtray and more manipulation of the spent filter than most people find acceptable, especially since the spent filter is covered with tobacco "tar". This "tar" can easily dirty ones hands, along with depositing nicotine stains on them. Another problem with U.S. Pat. No. 4,671,300 is that the fan provided in such ashtrays to draw the smoke also tends to draw ashes (and sometimes butts) from the tray, deliver them out the bottom of the ashtray, and deposit them on a supporting surface, such as a table or desk top on which the ashtray is resting.
Another consideration is a need to be compatible with equipment already in the field. For example, many stores have in stock a large supply of filters for the ashtray of U.S. Pat. No. 4,671,300, which they want to sell. Therefore, although the preferred filter location is in the ashtray lid, it is desirable to also provide an ashtray which accepts the existing filters. Moreover, it is always possible that some users may prefer the existing in-base filter system and wish to continue using it.
Accordingly, an object of the invention is to provide a new and improved smokeless ashtray. Here, an object is to make the filters of these ashtrays easier and more convenient to replace than with prior art smokeless ashtrays. Still another object is to eradicate some of the tendencies of the prior art smokeless ashtrays to scatter ash and sometimes butts over an area adjacent to the ashtray.
A further object of the invention is to provide an ashtray which may use filters taken from the existing supply of in-base filters. Here, an object is to provide an alternative in-base filter for those who may prefer this alternative.
Other objects of the invention are to provide a more compact ashtray which encloses the debris, ashes and butts, and to reduce odor in the vicinity of the ashtray.
In keeping with an aspect of the invention, these and other objects are accomplished within a box-like structure having a lid for enclosing the interior of the ashtray when not in use. The fact that the contents of the ashtray are entirely enclosed already provides some insurance that the odor of the ashes and butts will not reach the area surrounding the ashtray if it is not emptied after use. In addition, the cover of the ashtray contains a filter which may be replaced quickly and easily from a convenient work position. The ashtray's fan draws smoke into the filter but is not close enough to the debris in the ashtray to suck in the ashes or butts, as is sometimes a recurrent problem with prior art smokeless ashtrays.
A preferred embodiment of the inventive smokeless ashtray is seen in the attached drawings, in which:
FIG. 1 is a perspective view of the inventive ashtray in a closed condition;
FIG. 2 is a side elevation of the ashtray with the lid partially open;
FIG. 3 is a plan view looking down on the top of the inventive ashtray;
FIG. 4 is a cross-section of the closed ashtray taken along line 4--4 of FIG. 3;
FIG. 5 is a cross-section of the closed ashtray taken along line 5--5 of FIG. 3;
FIG. 6 is a cross-section, also taken along line 5--5 of FIG. 3, with the lid open;
FIG. 7 is a fragment of FIG. 6 showing a lid-controlled switch for operating the motor; and
FIG. 8 is a fragment taken from FIG. 6 which shows an inbase filter surrounding the motor, as an alternative to the inlid filter disclosed in FIG. 6.
FIG. 1 shows the inventive smokeless ashtray having a top lid 20 and a base 22 mounted on a pedestal 24. The top includes a groove or protrusion 26 which may be used to lift the lid. The ashtray operates only when the lid is in a raised position. When the lid is in a closed position, as shown in FIG. 1, the ashes, butts, etc. are enclosed and, therefore, the area surrounding the ashtray is fairly odor-free.
FIG. 2 shows the lid 20 partially raised to reveal several notches 28, 30, which are notches of different sizes, used to support a cigarette, or a cigar, respectively. The ashes deposited from such cigarettes and cigars are caught in a dish-shaped member 40 (FIGS. 4-6). The periphery of pedestal 24 (FIG. 2) contains air discharge ports 32, 34, 36, 38.
FIG. 3 is a top plan view which shows a position of two drycell batteries 42, 44, a filter 46, a fan 48, and a motor 50 used to drive the fan. The hinges 52, 54 mount lid 20 on the base 22 so that it may swing between a closed position (FIG. 5) and an open position . .(FIG. 6).!..
The lid construction is best seen in FIGS. 4, 5, 6. A first and outer part 56 of the lid is a closed box-like member which fits fairly closely over upstanding rim 59. The somewhat tight fit efficiently closes in and contains the odor of the ashtray debris. A second and inner part of the lid is a perforated, somewhat dome-like member 58 having one or more capture tabs 60 on one side. A plurality of keeper holes 62 are formed on the other side of member 58. These keeper holes 62 receive embossments 64 on the outer lid member 56 in order to lock the dome-like member 58 in place. A small space 66 between outer and inner lid parts 56, 58 enables a user to insert a fingernail and pull keeper hole 62 away from embossment 64, thereby removing the inner lid part 58 and exposing a filter 46.
The filter 46 uses an activated charcoal and is made of substantially the same material as that described in U.S. Pat. No. 4,671,300. When the inner lid part 58 is removed, the filter 46 is also easily removed from outer lid part 56, so that it all but falls out. When a new filter is installed it is simply pushed into outer lid part 56, with almost no force necessary to push this filter into place. In fact, only enough friction is needed to hold it in place while the inner lid part 58 is returned to lock it in place. In order to so return lid part 56, the capture tabs 60 are slipped behind a duct wall 70 on the outer lid part 56. Then, the upper portion of inner part 58 is pushed inwardly until the keeper holes 62 snap over the embossments 64. At this point, the filter installation has been completed, and the installer is unlikely to have dirtied his hands if he has been reasonably careful.
The lower or hinged side or outer lid part 56 is an air duct 72 which terminates in a toe 74, best seen in FIG. 7. The duct extends an enclosed air path from filter 46 to a motor and fan compartment 76. . .Toe 74 engages a ledge 78 (FIG. 7) which holds the lid in the upright slightly over center position, under the force of gravity..!. When the ledge is engaged, a set of contacts 80 close to start the motor 50 and therefore, at the same time, fan 48. The fan 48 draws air through an air path including filter 68, duct 72 and out the outlet ports 32-38. In doing so, any smoke from cigarettes or cigars is pulled into the air path through perforated dome 58. The draft of air created by this operation of the fan is relatively remote from the tray 40; therefore, the debris contained in the tray is neither attracted into the air path nor discharged from the ports 32-38 and onto the surface below the ashtray.
While the foregoing specification has described a battery driven D.C. motor, it should be understood that the invention also contemplates a use of other suitable power sources. For example, a standard 110 volt electrical cord may take power from a suitable wall outlet. On the other hand, an adapter may be used to power the motor from an automobile battery, as by plugging into a cigarette lighter socket. Still another suitable power supply may utilize a wall transformer which is mounted on a wall outlet and which may furnish any suitable D.C. voltage, such as 3V, 9V, etc. Any combination of these or other power supplies may be used.
FIG. 8 shows an alternative way of providing for an in-base filter of the type shown in U.S. Pat. No. 4,671,300 so that all filters in the field will not be made obsolete. More particularly, the tray 40 may be lifted out of the base and filter 84 may be dropped into the space surrounding motor 50 and contained within box 86. Of course, there is no reason for providing two filters, one in the lid and one in the base, however, the user may do so, if he wishes.
Those who are skilled in the art will readily perceive how to modify the invention. Therefore, the appended claims are to be construed to cover all equivalent structures which fall within the true scope and spirit of the invention.
