Meader, 3301 Woodbine Sh, Chevy Chase, Md. Filed .Ian. 19, 1962, Ser. No. 167,261 Ciaims. (Cl. 250-51) This invention relates to the sterilization of articles and deodorization of air, and more particularly to a device for supporting and sterilizing articles such as a plurality of toothbrushes, a drinking container, and/or the like, and for deodorizing the surrounding air.

The present device utilizes as a sterilizing and deodorizing source electrically actuated lamps or bulbs of the type adapted to emit electromagnetic waves of a germicidal frequency and to generate a gas capable of deodorizing air diffused therewith. Lamps or bulbs of this type are well-known and one embodiment thereof is produced by Westinghouse Electric Corporation under the trademark Sterilamp as disclosed in the Westinghouse publication, Sterilamp Germicidal Ultraviolet Tubes and their Application. As set forth in the above-mentioned publication, lamps of this type have been used in a variety of different applications, both for personal protection, product protection, animal protection and air duct irradiation. The patented literature contains numerous proposals of devices utilizing lamps of the type mentioned above for sterilizing various articles and for deodorizing room air.

One of the most concentrated areas needing sterilization and deodorization in any dwelling place is the bathroom. There have been many proposals and actual devices produced commercially to, in some way, alleviate this condition utilizing as the sterilization and deodorization source lamps of the type mentioned above. For example, lamps of this type have been mounted in fixtures in the ceiling or on the upper portion of the wall which will serve to emit sterilizing rays in the upper portion of the room and to generate a germicidal deodorizing gas, such as ozone, which will diffuse with the air throughout the room.

In general it can be stated that devices of this type, while serving to freshen the air, do not have the ability to completely sterilize those articles in the room which require a concentrated dosage of the germicidal rays in order to effect complete sterilization. Efforts in this regard have also been proposed and indeed some devices have been actually produced. For example, ultraviolet rays adapted to impinge upon a toilet seat when disposed in its raised position have been utilized to good advantage.

Of the articles contained in most bathrooms, the two which present the most severe conditions requiring sterilization are toothbrushes and drinking containers. The drinking containers in the bathroom are usually used by several different people, several times each day; and toothbrushes are likewise frequently used. Both of these articles may sometimes constitute aggravated carriers of germs which, due to their frequency of use may be undesirably spread among the different occupants of the dwelling.

There have been numerous proposals in the patented literature dealing with the sterilization of toothbrushes by the use of germicidal lamps. In general, the devices proposed have embodied closed housings similar to medicine cabinets and the like in which the toothbrushes are stored for sterilization. These devices have the disadvantage that they require considerable space, or alternatively, severely limit the amount of medicine cabinet space provided, and do not provide for convenient access to the toothbrushes. Moreover, where a closed housing is utilized to sterilize articles the cost of the device is increased by the necessity to provide parts such as doors, drawers, trays or the like which must be frequently and easily moved. Finally, a closed housing structure prevents the diifusion of the deodorizing gas generated by the lamps into the surrounding air to effect deodorization of the room.

Accordingly, an object of the present invention is the provision of a device for supporting and sterilizing articles such as tooth brushes, drinking containers and/or the like in readily accessible positions and for deodorizing the surrounding air.

Another object of the present invention is the provision of a device of the type described which is capable of rapidly and completely sterilizing the articles supported thereby.

Another object of the present invention is the provision of a device of the type described which functions as a convenient night light.

A further object of the present invention is the provision of a device of the type described which substantially confines the sterilizing ultraviolet rays within the vicinity of the articles supported thereby, so as to insure against excessive exterior exposure of the rays.

Still another object of the present invention is the provision of a device of the type described in which access to the lamps within the housing means of the device for purposes of replacement is sufficiently diflicult to prevent access by small children.

Still another object of the present invention is the provision of a device of the type described having improved means for supporting a plurality of toothbrushes in positions of easy accessibility while at the same time insuring rapid and complete sterilization thereof.

Still another object of the present invention is the provision of a device of the type described in which the toothbrush supporting means is easily removable for purposes of cleaning.

Still another object of the present invention is the provision of a device of the type described having improved means for supporting a drinking container in a position of easy accessibility while at the same time insuring rapid and complete sterilization thereof.

Still another object of the present invention is the provision of a device of the type described which is simple in construction, effective in operation and requires a minimum of maintenance.

These and other objects of the present invention will become more apparent during the course of the following detailed description and appended claims.

The invention may best be understood with reference to the accompanying drawings wherein an illustrative embodiment is shown.

Referring now more particularly to the drawings, there is shown in FIGURE 1 thereof a device for supporting and sterilizing a plurality of toothbrushes and a drinking container and for deodorizing the surrounding air embodying the principles of the present invention, which is generally designated by the numeral 10. The device comprises a housing, generally indicated at 12, which may be of any desirable construction and made of any desirable material. As shown, there is provided a bottom wall 14 of rectangular configuration having a front Wall section 16 extending upwardly from the front edge thereof, the front wall section 16 having an inwardly extending downwardly and rearwardly inclined flange 18 formed thereon. The bottom wall 14, front wall section 16 and flange 18 may be made of any suitable material and, as shown, they are formed of a single piece of sheet metal bent into the proper configuration. Fixedly secured, as by welding or the like, to opposite ends of the bottom wall 14, front wall section 16, and flange 18, is a pair of

upright end walls

20 and 22 which likewise may be of any suitable material and, as shown, are of sheet metal construction. Extending between the end walls 20 and '22 at a position above the flange 18 is a thin front wall section 24 having its ends suitably fixed to the associated end walls as by welding or the like.

The inner edge of the flange 18, the lower edge of the front wall section 24 and the adjacent edges of the end walls define a horizontally extending opening 26 for receiving a toothbrush support in the form of a removable tray, generally indicated at 23. It will be noted that each of the end walls has an angle iron section welded thereto providing a flange 30 extending rearwardly and downwardly from the flange 18 so as to support the tray 28 at its ends within the housing.

The housing 12 also includes a back wall or panel 32 which likewise may be made of any suitable material and, as shown, is of sheet metal construction. The back wall is detachably secured to the bottom and end walls by any suitable means such as a bottom flange 34 on the back wall which engages the rear marginal edge portion of the upper surface of the bottom wall and a pair of inwardly turned vertically disposed flanges 36 formed on the end walls. Suitable fastening elements, such as countersunk bolt assemblies 38, extend through the back panel and the flanges 36 to detachably fixedly secure the back wall with the bottom and end walls.

Carried by the back wall is a pair of electrical socket fixtures or units 40 of conventional design. Any suitable means may be provided for mounting each of the socket units on the back wall and, as shown, such means includes opposed sheet metal brackets 42 welded or otherwise secured to the back wall 32 and providing substantially circular openings to receive and support the socket units. Threaded within the socket units is a pair of lamps or bulbs 44 which are of the type adapted to emit electromagnetic rays of a germicidal frequency and to generate a germicidal gas capable of deodorizing air difiused therewith. Lamps of this type usually require a starting device, such as the ballast 46 shown in FIG- URE 4. In accordance with usual practice, the lamps 44 are connected in series with each other and with the ballast 46 and, if desired, an on and olf switch 48 may also be connected in series to control the circuit.

As shown, the circuit includes a dual lead insulated cord 50 having a male outlet 52 connected at one end thereof. The cord extends through a suitable eyelet 54 in the end wall 22 of the housing and one lead of the cord is connected with one contact of the switch 48 while the other lead is connected with one contact of one of the socket units. The other contact of the one socket unit is interconnected with a contact of the other socket unit by a lead 56, and a lead 58 is connected with the other contact of the other socket unit and extends to one contact of the ballast 46 as shown in FIGURE 4. Finally, the other contact of the ballast is connected to one end of a lead 69, the opposite end of which is connected to the other contact of the switch. It will be understood that the circuit may also have connected in series or parallel therewith an outlet socket (not shown) which may be suitably mounted in a wall of the housing for exterior use, as by an electric shaver or the like.

The housing also includes a wall unit, generally indicated at 62, which is preferably made of an interiorly beaded translucent material such as polyethylene, nylon, high impact polystyrene or the like. The wall unit 62 includes a pair of horizontal top wall sections 64 and a central top wall section 66 which is inclined downwardly and forwardly. The inner edge of each horizontal top wall section is connected with the adjacent edge of the inclined top wall section by an upright triangular wall section 68'. Extending downwardly from the forward edges of the horizontal top wall sections, inclined top wall section and triangular Wall sections is a front wall section 70, the lower edge of which is arranged to extend in overlapping relation to the front wall section 24 previously described. The wall unit is secured to the upper forward portion of the

end walls

20 and 22 by any suitable means, such as a pair of fastening elements preferably in the form of countersunk bolt assemblies 72 extending through the horizontal top wall sections and a pair of flanges 74 extending inwardly from the upper edge of the end walls.

Formed in the inclined top wall section 66 of the unit 62 is an open-ing 76 which is preferably circular in configuration and of a size to receive therein a drinking container such as a container C as shown in FIGURES 1 and 7. Preferably, the unit 62 includes an integral depending annular wall or lip portion 78 which serves to prevent direct visibility through the opening 76 of the filaments of the lamps 44, as best shown in FIGURE 3.

In a like manner, in order to prevent direct visibility through the toothbrush supporting tray opening 26, there is provided a housing wall member 80 having a vertical flange 82 rigidly secured, as by welding or the like, to the interior surface of the front wall section 24, a horizontal flange 84 extending inwardly therefrom for engaging the lower edge of the front wall section 70 of the wall unit 62 and a downwardly and inwardly inclined flange or wall portion 86 which serves to prevent direct vision of the filaments of the lamps 4-4 through the opening 26.

Disposed below the drinking container receiving opening 76 and the lower edge of the annular lip is a pair of downwardly and forwardly inclined strap members 88 which constitute means for engaging the drinking container and supporting the same in proper relation within the opening 70. The strap members 88 may be mounted within the housing in any suitable manner, and, as shown, they are provided with rearward depending bent portions 90 which are fixed to the back wall as by welding or the like.

In a like manner, the toothbrush supporting tray is provided with suitable means for supporting a plurality of toothbrushes T therein. As best shown in FIGURE 6, the tray '28 is of shallow partitioned construction and includes a bottom wall 92 having a lower inclined upright wall 94 and a plurality of forwardly and rearwardly extending partition walls 96 defining a central compartment 98 and three toothbrush receiving compartments 100 on each side thereof. The partition members defining the central compartment 98 have their upper ends interconnected by an inclined wall section 102 which is provided with a handle 104 to facilitate movement of the tray into and out of the housing. It will be noted that the upper ends of the toothbrush receiving compartments are open.

Operation The present device is arranged to be utilized in the bathrooms of dwelling homes, hotels, motels and the like. Preferably, the lamps are continuously actuated although it will be understood that the user may control the actuation of the same by turning the switch 48 Whenever desired. While any lamp of the type described may be utilized, a specific example of a preferred lamp is the 7491-1 lamp manufactured by Westinghouse Electric Corporation and sold under the trademark Odorout. Each of these lamps has a rated wattage of 3 /2 watts, an operating amperage of 0.350 amps, an operating voltage of to 12 volts, a starting voltage of 24 volts, and an average rated life of approximately 4,000 hours when burned at 8 hours the start at 80 F. or more temperature and under specified test conditions, as noted in the above-mentioned Westinghouse publication so that a pair of such lamps can be operated continuously for an extended period of time at a very low cost.

It will be understood that a lamp of the type mentioned above is capable of generating electromagnetic rays having wave lengths of ultraviolet frequency equivalent to 2537 Angstrom units. Approximately 95% of the ultraviolet radiations from lamps of this type are in the 2537 Angstrom unit region. This is the region in the ultraviolet spectrum which is near the peak in germicidal effectiveness. Each 794H lamp has a rated ultraviolet output of 0.1 total watts and 1.2 microwatts per square centimeter at one meter from the lamp. In addition, the lamp is capable of producing shorter wave length ultraviolet rays of 1850 Angstrom units. This latter wave length has the power of generating ozone in the air, which is a form of oxygen and is a germicidal agent in itself. Each 794H lamp has a ozone generating rating of 0.023 gr./hour.

Utilizing two lamps of this type, complete sterilization of toothbrushes can be achieved in a matter of two or three hours, while complete sterilization of a drinking container is achieved in less than 1O minutes. Ozone distribution in the surrounding air of a bathroom of average size sufiicient to deodorize the same is accomplished in a relatively short period of time. Moreover, this deodorization is maintained so long as the lamps remain actuated without generating a concentration of ozone in the air beyond a permissible amount under normal conditions.

The present device is constructed so as to provide for optimum ease and convenience in supporting the toothbrushes and drinking container while at the same time presenting these articles to the source of sterilizing rays and sterilizing gas in such a way as to effect rapid and complete sterilization thereof. As best shown in FIG- URE 8, it will be noted that the toothbrushes are supported in the tray 28 with the brush ends disposed in a position of exposure to the direct ultraviolet rays of the lamps. The opposite ends or handle ends of the toothbrushes extend outwardly of the housing, as shown in FIGURE 1, so that they may be easily and conveniently grasped by the user. Thus, the toothbrush supporting tray 28 provides for convenient access to the toothbrushes and permits the user to remove the toothbrushes fro-m supported relation and place the toothbrushes in supported relation without the necessity of opening doors or any other manipulation. When the toothbrushes are in supported relation they are presented to the sterilizing source in a most advantageous manner as close as possible to the source without the necessity of providing obstructing parts between the source and the brushes. The angle at which the toothbrushes are supported as shown in the drawings is approximately 10 and this is regarded to be an optimum position for achieving the results set forth above.

It will be noted that the brush ends of the toothbrushes are disposed within the housing when supported in proper relation and thus are maintained in a sterilized zone rather than in the surrounding air. While there is adequate air circulation through the interior of the housing to permit the toothbrushes to dry quite rapidly, the immediate air surrounding the toothbrushes is sterilized so as to prevent any re-contamination. It will be understood that the tray 28 itself is removable from the housing solely for the purpose of cleaning and that, under normal conditions, it would not be necessary to effect such removal for cleaning purposes except at infrequent intervals.

The opening 26 provided in the housing, as well as the open forward ends of the toothbrush compartments of the tray 28, provide an inlet for the surrounding air to enter the interior of the housing as shown by the arrows in FIGURE 7. The lamps 44- also give olf some heat and, as a result, there is established within the housing a thermally induced circulation from the inlet through the interior of the housing and upwardly and outwardly of the housing through the container receiving opening 76. This circulation enhances the generation of ozone by the lamps and has the effect of distributing the ozone generated into the surrounding air in a rapid manner. In addition, as

shown in FiGURE 7, the container receiving opening 76 is preferably of a size greater than the size of the container C to be supported therein. Thus, even when a container is supported within the opening there is an ample outlet for the passage of the ozone diffused air from the interior of the housing into the surrounding air to effect deodorization thereof. It will also be noted that the support of the container C within the device in inverted relation achieves several advantages. First, by supporting the container within the opening 76, which constitutes the outlet for the ozone diffused air, the ozone generated within the housing will pass upwardly into the interior of the container, thus achieving a more effective sterilization of this hard-to-reach area. In a like manner, the ozone passing by the exterior of the container will hasten sterilization of the exterior thereof. Second, the area of the container in greatest need of sterilization is the exterior marginal portion adjacent the open end which is engaged by the lips of the user and it will be noted that the strap members 88 are disposed below the depending lip 78 approximately one inch, so as to present this area of the container for exposure to the direct ultraviolet rays emitted by the lamps 44. This insures rapid and complete sterilization of this critical area of the container by concentrating the rays thereon. Finally, another advantage of supporting the container in inverted relation is that any residual liquid therein will drain out into the central compartment 98 of the tray 28, thus insuring that the container will be dry and sterile in a short period of time. In this regard, it will be noted that the container is supported in an inclined plane disposed at an angle of approximately 11 with respect to the horizontal. This inclination, which is regarded to be an optimum, facilitates the drainage of the liquid from the container into the central tray compartment and at the same time stably supports the container and presents the upper closed end portion thereof, which extends above the top wall sections 64 and 66 of the housing, in a most convenient position of access.

Another significant feature of the present construction is that the housing provides wall means which positively prevent direct vision of the filaments of the lamps either through the openings 26 or 76 or from any exterior position of normal use. The housing, as described above, is particularly adapted to be mounted on a vertical wall and for this purpose it will be noted there is provided in the back wall a pair of key-shaped knockout portions 196 shown in dotted lines in FIGURE 3,

through which suitable fastening elements (not shown) may extend to secure the same to the vertical wall surface. It will also be understood that the bottom wall may be provided with suitable rubber grommets or the like (not shown) enabling the device to be conveniently supported on a horizontal surface. In both instances the housing 12 provides a complete blockage of direct rays outwardly of the housing. As is well-known, continned exposure to direct ultraviolet rays may produce transitory conditions such as reddening of the skin and irritation of the eyes. The present structure thus prevents exterior exposure of these direct rays. Moreover, access to the lamps 54- for replacement purposes can be obtained by simply removing the fastening elements or bolts 72 which secure the Wall unit 62 in the upper forward portion of the housing. The manipulation of these bolts provides simplicity of access when appropriate tools are at hand while, at the same time, preventing easy access to the exposed lamps by small children.

It will be understood that the present structure constitutes a device which, as indicated above, may be either mounted on a wall or supported on a horizontal surface and under these circumstances it is preferable to provide a housing which is completely enclosed except for the inlet and outlet openings provided. It will be understood, however, that the device is susceptible to being installed as built-in equipment, such as in new construction, in Whcih case some of the walls of the device may be provided by the built-in structure itself. In any event, it is highly desirable that the filaments of the lamps be protected against direct visibility from any position exterior of the housing when the device is properly installed.

Finally, by utilizing a translucent plastic material in the wall unit 62, there is provided adequate safeguards against exterior exposure of the direct ultraviolet rays while, at the same time, permitting exterior visibility of the violet light emitted by the bulbs. Thus, the present device provides an effective night light for the bathroom. In this regard, the interior surface of the plastic material may be beaded in a known manner, to diffuse this light over the area of the wall unit to enhance the effect.

It thus will be seen that the objects of this invention have been fully and efiectively accomplished. It will be realized, however, that the foregoing specific embodiment has been shown and described only for the purpose of illustrating the principles of this invention and is subject to extensive change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
